Description

The invention relates to a processing machine with at least one processing unit and a method for processing a substrate according to the preamble of claim 1 and claim 12.

During punching, substrate sheets pass through a cylinder gap between cylinders that carry effective tools or tool parts (e.g. cutting tools, punching tools, creasing tools, perforating tools, scribing tools, embossing tools or grooving tools). In a rotary die cutter, a die cylinder works against a counter die cylinder.

In sheetfed presses, the anvil cylinder is equipped with gripper systems that are located in a cylinder channel. If the die cylinder is equipped with clamping devices for the die, this also has a channel. If the die cylinder is a magnetic cylinder, the clamping device and thus the cylinder channel are omitted. During the punching process, both cylinder surfaces face each other from the beginning to the end of the sheet and the cylinders can build up the necessary punching pressure. At least one of the two cylinders in contact has a cylinder channel. In the area of the cylinder channel, the two cylinders are not in contact. As soon as the cylinders come into contact again, cylinder start-up vibrations occur, since a sudden force is applied to the two cylinders, in particular due to the pressure required for punching. This leads to vibrations that can have a negative impact on the punching result.

through the DE 10 2018 219 712 A1 such a rotary punch is known. Especially the document also discloses a magnetically designed punching cylinder without a cylinder channel.

the DE 101 47 486 A1 discloses a punching or cutting device with a magnetic cylinder and a suction device arranged next to the magnetic cylinder for sucking off punched-out pieces of material.

The pamphlet DD1 16 783 A1 relates to an anvil cylinder for punching machines with a tubular outer surface of great hardness with an axially running recess for receiving the gripper device. It cannot be inferred from the document that a contact element is provided on the trailing edge, which is arranged to widen the surface of the cylinder barrel.

The pamphlet DE 10 2009 039 553 A1 discloses a punching machine with an anvil cylinder, a protector plate being provided on the anvil cylinder. There is no indication of a contact element on the trailing edge, which is also arranged to widen the surface of the anvil cylinder.

The object of the invention is to provide a processing machine with at least one processing unit and a method for processing a substrate.

The object is achieved according to the invention by the features of claim 1 and claim 12.

The advantages that can be achieved with the invention are, in particular, that cylinder start-up vibrations, which have a harmful effect on the punching pressure and thus on the punching result, are avoided on the sheet. If at least one cylinder channel to another cylinder or another cylinder channel is arranged opposite, the punching pressure is zero. As soon as the cylinders come into contact again, cylinder start-up vibrations occur, since a sudden force is applied to the two cylinders, in particular due to the pressure required for punching. As a result, the rotary sheet punching process is characterized by a constant change in punching pressure between zero and the set punching pressure. This change in punching pressure corresponds to a change in force, which entails a constant change in cylinder deformation. A steep increase in force after passing through the channel phase leads to a short cylinder start-up oscillation, which has a damaging effect on the punching pressure and thus on the punching result. Cylinder vibration can be terminated and/or reduced by the invention before the punching process begins. Even at a high punching speed, cylinder start-up vibrations can be prevented.

Another advantage that can be achieved with the invention is that the start of punching does not have to be moved backwards by preventing cylinder start-up oscillations. In particular, there is only a small amount of material waste despite the high punching speed. In particular, this is achieved in that cylinder start-up vibrations are relocated in front of the beginning of the sheet by means of a start-up element. A typical start of punching of 13 mm to 17 mm on the substrate can also be further reduced by the invention. Another advantage that can be achieved with the invention consists in particular in the fact that set-up work can be saved. Previously, a machine operator had to carry out such setup work in the area of cylinder start-up vibrations on the punching plates.

A further advantage that can be achieved with the invention consists in particular in the fact that the punching quality can be ensured at higher speeds.

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.

The device for processing substrates 01 with a separating device 02, with which the processed substrate 01 can be separated into at least one waste part 09 and at least one panel 10, can be embodied as an independent machine and in this case has a feed system for substrate 01, which is not described in detail .

According to a further embodiment, separating device 02 is part of a substrate-processing machine, in particular a sheet-processing machine, and is operated inline with the units of the sheet-processing machine. As a sheet-processing machine, a sheet-fed printing machine is provided in particular, as z. Am 1 is shown. The invention is described below using the example of a sheet-fed printing press, in particular an offset sheet-fed printing press, with this description also being intended to apply mutatis mutandis to other sheet-processing machines and to an embodiment of the device as an independent machine.

The sheet-fed printing press includes a feed system for substrates 01, also referred to as feeder 07. Substrates 01 are understood to mean, in particular, sheet-shaped workpieces made of paper, cardboard, cardboard, corrugated cardboard, plastic or the like, which are preferably printable or printed. The substrates 01 are present as a stack in the feeder 07 of the sheet-fed printing press and are separated by it and fed to the units of the sheet-fed printing press downstream of the feeder 17 via an acceleration system 08. The sheet-fed printing press comprises at least one, preferably a plurality of, printing units 06. The printing units 06 each comprise, in particular, a printing cylinder 41 and a preferably acting transfer drum 42 formed sheet guiding cylinder 42. The impression cylinder 41 is associated with a blanket cylinder 43 carrying a blanket and this in turn is assigned a plate cylinder 44 carrying a printing plate. The plate cylinder 44 is in contact with an inking unit 45 and preferably also with a dampening unit. In printing unit 06, substrate sheet 01 is guided in a manner known per se by the sheet holding systems provided on impression cylinder 41 and sheet guiding cylinder 42, is printed in the printing gap formed between impression cylinder 41 and blanket cylinder 43, and is fed to the subsequent unit of the sheet-fed printing press, e.g. B. in the form of the next printing unit 06 handed over. One or more processing units 46 can be configured downstream of the printing unit(s) 06 or between the printing units 06. The processing units 46 preferably comprise two processing cylinders 96, 97, one of which, preferably the lower one, has a sheet holding system and the other, preferably the upper one, has a tool carrier. The sheet holding system of the processing cylinder 96 can be designed as a clamping gripper system or as a suction gripper system. It is functionally and preferably identical to the gripper system (clamping gripper system or suction gripper system) of the transport cylinder 03, to the description of which reference is made.

The processing cylinders are associated with one another to form a cylinder gap. At least one of the processing cylinders carries a tool 116. In the simplest case, a pair of processing cylinders is formed by the impression cylinder 41 and blanket cylinder 43 of a printing unit 06. In this case, a printing unit 06 serves as the processing unit 46. In this case, the clamping device for the rubber blanket is used to fasten the tool 116 on the rubber blanket cylinder 43.

The processing cylinders can be designed in many different ways.

According to an embodiment particularly suitable for die-cutting and perforating applications, the upper processing cylinder is in the form of a solid magnetic cylinder or carrier cylinder designed with magnet segments for holding magnetic sheets or magnetic sheets and the lower processing cylinder as a surface-hardened cylinder or with a hardened sheet metal attached thereto.

According to another embodiment, which is particularly suitable for embossing or creasing or grooving applications, the upper processing cylinder is a full magnetic cylinder or carrier cylinder with magnet segments for receiving magnetic sheets or magnetic sheets and the lower processing cylinder is a surface-hardened cylinder or with a hardened sheet metal attached or formed with a sheet of hard rubber/plastic.

In all of the cases mentioned, the lower processing cylinder can be provided with tool carriers or lift carriers that act mechanically, in particular in a positive or non-positive manner. The non-positively acting tool carriers or elevator carriers are designed in particular to act magnetically.

According to a further preferred embodiment, the device for treating substrates 01, which can be embodied as a sheet-processing machine or can be part of it, in particular a processing unit 46, comprises a first and a second processing cylinder 96, 97. Between the first and a second processing cylinder 96 , 97, substrate sheets 01 can be inserted, which are processed as they pass through the cylinder gap between the processing cylinders 96, 97. The first processing cylinder 96 has a sheet holding system. The first and/or the second processing cylinder 96, 97 have a tool carrier for receiving a tool 116 or a tool part, which preferably comes from the group of cutting tools, stamping tools, creasing tools, perforating tools or grooving tools. On the side facing away from the first processing cylinder 96 , the second processing cylinder 97 is assigned a counter-cylinder 98 which is in surface contact with the second processing cylinder 97 .

Counter cylinder 98 is assigned to processing cylinder 97 in such a way that when processing cylinder 97 deflects, as occurs when processing substrate sheet 01 in the gap between the two processing cylinders 96, 97, the force of the resulting bending force of second processing cylinder 97 causes counter cylinder 98, preferably in its center or close to its center.

From a geometric point of view, the centers of the first and second processing cylinders 96, 97 and the counter cylinder 98 preferably lie on an imaginary straight line, or the centers of the second processing cylinder 97 and the counter cylinder 98 lie on a straight line that is opposite to a straight line on which the centers of the the first and second processing cylinders 96, 97 are inclined by an angle of less than or equal to 10 degrees.

The counter cylinder 98 can have the same diameter as the second processing cylinder 97.

Likewise, the counter-cylinder 98 and the second processing cylinder 97 can have bearer rings which are in rolling contact with one another. It is also possible that the surface contact between the anvil cylinder 98 and the second processing cylinder 97 is limited to the contact between the bearer rings. In this case, at least one bending of the second processing cylinder 97 is counteracted in the areas between its bearing points in a frame wall and the bearer ring adjacent to the respective bearing point.

The use of bearer rings is known in printing machine construction. The bearer rings on printing presses are placed on the sides of the printing cylinders. The Schmitz ring is intended to prevent Schmitz. It is made of tempered steel and is ground with high precision round and true to size. The Schmitz ring is about 1-4 cm wide and rolls either on the foundation rail or on the bearer ring of the counter cylinder. The circumference of the bearer ring is exactly the circumference of the elevator or it has exactly the circumference of the mold, depending on which machine part it is attached to. The bearer ring is an element of the restricted guidance on printing machines with a central drive and compensates for minor bearing inaccuracies as well as uneven input and output from the gear drive of the printing machines.

In the case of the formation of bearer rings, a device for adjusting the pressure between the bearer rings by shifting the counter-cylinder 98 and/or the second processing cylinder 97 is advantageously provided.

The counter-cylinder 98 is preferably associated with a device for fixing an elevator. This enables a dressing to be arranged on counter cylinder 98 to ensure that it is in surface contact, in particular rolling contact, with processing cylinder 97 or with the tool 116 arranged on its surface, even when tool 116 is arranged on second processing cylinder 97, the thickness of which can vary , stands. A device for tensioning the packing in the circumferential direction of the counter-cylinder 98 is preferably also assigned to the counter-cylinder 98, which can form a structural unit with the device for fixing a packing.

In particular for the use of a profiled dressing, for example in the form of a matrix, it has proven to be advantageous if the counter cylinder 98 has a register system for positioning a dressing on the counter cylinder 98 .

According to a further preferred embodiment, which facilitates the replacement of tool parts, the device for treating substrates 01 comprises a processing unit 46 with two interacting processing cylinders 96, 97, between which the substrate 01 can be inserted. The substrate 01 is processed as it passes through tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools or grooving tools that are effective in the cylinder gap between the processing cylinders 96, 97. At least one of the processing cylinders 96, 97 is designed as a magnetic cylinder. A peeling device for peeling off at least one tool part is assigned to the processing cylinder 96, 97 designed as a magnetic cylinder.

According to a further preferred embodiment, which facilitates the replacement of tool parts, the device for treating substrates 01 comprises a separating device with a transport cylinder 03 and a stripping cylinder 04, between which the substrate 01 can be inserted. As it passes through the cylinder gap between the transport cylinder 03 and the stripping cylinder 04, the substrate 01 is separated into at least one waste part 09 and at least one blank 10 by at least one elevator 05. The transport cylinder 03 and/or the stripping cylinder 04 are designed as magnetic cylinders. A peeling device 103 for peeling off the at least one dressing 05 is assigned to the transport cylinder 03 and/or the stripping cylinder 04. See in particular Figure 47 and Figure 48 . The peeling device 103 is designed to be able to be placed on and/or off the cylinder to which it is assigned and which is designed to carry a packing 05, in particular the processing cylinder 96, 97 or the transport cylinder 03 or the stripping cylinder 04. The peeling device 103 has a peeling edge 104 . When the peeling device 103 is placed against the respective cylinder, the peeling edge 104 preferably extends tangentially or approximately tangentially to the periphery of the cylinder to which it is assigned, i.e. in particular to the processing cylinder 96, 97, transport cylinder 03 or stripping cylinder 04. It also proves advantageous if the peeling device 103 forms a structural unit with a guard 70, 71. The protection 70, 71 can be, for example, any part of the housing of a processing unit 46 or a cutting unit 02.2 that protects the operator from injury from rotating cylinders or noise or Dust emissions avoided or reduced. It is also possible to assign the peeling device 103 to parts of the plate changing unit or the elevator changing device.

If the peeling device 103 forms a structural unit with a protection 70, 71, the structural unit can fulfill the function as a peeling device 103 in one position and as a protection 70, 71 in another position.

The peeling device 103 preferably has a holding element for fixing the tool parts or the at least one dressing 05 in place. The holding element can act pneumatically or magnetically or be designed in some other suitable way, e.g. B. in the form of a stage or latch.

In order to ensure that the peeling device 103 grips an edge of the tool part or the at least one dressing 05, the tool part or the at least one dressing 05 can be lifted off manually. According to an advantageous alternative, an ejector is configured for this purpose, which is assigned to processing cylinder 96, 97 and/or transport cylinder 03 and/or stripping cylinder 04 and which is used to at least partially lift tool parts or the at least one elevator 05 from the surface of the Processing cylinder 96, 97 or the transport cylinder 03 or the stripping cylinder 04 is formed.

A drive which acts on the processing cylinder 96, 97 and/or the transport cylinder 03 and/or the stripping cylinder 04 and with which a drive controller interacts is preferably provided. The drive control causes the processing cylinder 96, 97 and/or the transport cylinder 03 and/or the stripping cylinder 04 to be automatically positioned in a position in which one end of a tool part or of the at least one elevator 05 is opposite the peeling device 103 and/or is in the Effective range of the peeling device 103, in particular of the peeling edge 104 is located. After positioning, the drive controller can rotate the processing cylinder 96, 97 and/or the transport cylinder 03 and/or the stripping cylinder 04 in such a way that the other end of the tool part or the at least one elevator 05 is opposite the peeling device 103 and/or is in the effective area of the peeling device 103 is located. During the twisting, the peeling device 103 peels the tool part or the at least one dressing 05 from the respective cylinder surface. Between the positioning and turning of the processing cylinder 96, 97 and/or the transport cylinder 03 and/or the stripping cylinder 04, the ejector is used to at least partially lift the respective tool part or the at least one elevator 05 from the surface of the processing cylinder 96, 97 or the transport cylinder 03 or the stripping cylinder 04 is preferably activated.

In the above context, a magnetic cylinder is understood to mean all types of cylinders or drums that exert a magnetic force on adjacent ferromagnetic elements in the area of their periphery, in particular on tools 116 or tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools or grooving tools . Such a cylinder can be designed as a full magnet cylinder or cylinder with embedded magnet segments or as a carrier cylinder for magnet segments or magnet sheets arranged on it, which applies to the design as a drum in the analogous sense.

According to a further preferred embodiment, the device for treating substrates 01, which can be embodied as a sheet-processing machine or can be a component thereof, comprises units that are preferably embodied as printing units 06 and processing units 46, as well as other units that are arranged individually or in groups in any order could be.

For all described versions with a film applicator or

Window application unit 85, it makes sense if a turning device is arranged directly or indirectly in front of the unit in which the adhesive is applied. This has the advantage that z. B. for the production of envelopes, the cutting or punching lines or material tears as a result of cutting or punching in the substrate 01 would appear on the inside of the envelopes, where they are less disruptive than on the outside.

A preferred method for treating sheet-shaped substrates 01 is described below, which uses one of the versions according to 33 to 46 can be carried out.

The procedure is as follows.

In a punching step, window-shaped areas are punched in the substrates 01, with material connections being retained. In a separating method step, which preferably immediately follows the punching method step, the window-shaped areas are broken out of the substrates 01, with the material connections being severed so that window-shaped recesses are formed in the substrates 01. In a coating process step, which preferably immediately follows the separating process step, the substrates 01 are coated with adhesive in the area adjacent to the window-shaped recesses. In a window application process step, film sections whose extent is greater than the extent of the window-shaped recesses are positioned over the window-shaped recesses and fixed with the adhesive.

In the punching process step, blanks 10 are preferably punched into the substrates 01, in each of which at least one window-shaped area is arranged, with further material connections between the blanks 10 and between blanks 10 and waste parts 09 being retained. In the case of production of envelopes with

window, such a benefit 10 would represent an unfolded envelope.

After window application, the substrates 01 are either placed directly on a stack or on a conveyor belt 29, 30; B. the outer frame are severed. It is also possible to print the substrates 01 before the punching process step. The method steps described are preferably carried out in consecutive units of a sheet-processing machine, in particular a rotary printing machine.

A further embodiment relates to a method for treating sheet-shaped substrates 01.

The procedure is as follows.

A respective substrate sheet 01 is separated from a stack formed from substrate sheets 01 by a feeder 07, then embossed and/or dried in a first processing unit 46, then creased or punched and/or kiss-cut in a second processing unit 46, and then in a third processing unit 46 punched and/or punched and/or perforated and/or embossed and/or grooved. The respective substrate sheet 01 is preferably printed in one or more printing units 06 and/or varnished in one or more coating units between being separated in the feeder 07 and being processed in the first processing unit 46. Alternatively or additionally, the printing and/or varnishing in at least one printing or varnishing unit can also take place between the treatment in two of the processing units 46 and/or after the treatment in the last processing unit 46. After separation, the sheet-like substrates 01 or blanks 10 are preferably stacked in a delivery 99 or on a conveyor belt 29, 30 or deposited in succession, scaled or unscaled.

In this context, cutting is understood to mean, in particular, the complete mechanical separation of an unpunched material by pressure, with shear stresses predominantly acting. The cutting process can be done with a knife cut, or with a shear cut, or with a burst cut principle.

Punching is understood to mean in particular the dividing of materials in a parting line that deviates from a straight line. Preferably, the production of cutouts and blanks with self-contained boundary lines is considered. In some cases, however, open cuts are also made by punching, e.g. B. the rounding of corners and register punching.

Embossing is understood to mean the processing of materials by pressure with appropriate tools 116, the material being shaped and/or deformed in a relief manner.

Grooves mean the processing of materials by pressure with appropriate tools 116, with elongated, narrow indentations being made in the surface of the material.

Perforating is understood to mean the processing of materials by pressure with appropriate tools 116, with a large number of holes, usually arranged in a line, being introduced into the material. The distances between the holes are preferably the same.

To carry out the individual process steps of the described process, an independent plant is preferably provided in each case, which can be combined with other plants in any order to implement changed production processes can be combined. For this purpose, the works preferably have independent frame walls. In particular, the punching process step or the punching and cutting process steps are carried out with a punching unit, the cutting process step with a cutting unit 02.2, the coating process step with a coating unit 88.2, the window application process step or the coating and window application process steps with a window application unit 85. Each of the plants mentioned, with the exception of the last plant, hands over the substrate 01 to the plant following it after at least one process step has been carried out.

Depending on the machine configuration implemented in each case, with or without foil applicator unit or window applicator unit 85, after going through various processing stages, either substrate sheets 01 (panels 10 connected to one another via residual webs, with or without a frame) are present, which are stacked in a delivery 99, or blanks are punched out 10, which are preferably conveyed on a conveyor belt 30 from the machine. These blanks 10 are preferably divided into streams of blanks which are laterally spaced from one another. For this purpose, several pairs of bugs are arranged following the conveyor belt 30, with each pair of rollers being arranged diverging from the other pairs of rollers, ie with a different lateral angular position. The pairs of rollers each form a nip and rotate at a peripheral speed that is greater than the speed of the conveyor belt 30. The panels 10 lying next to one another and one behind the other are conveyed by the conveyor belt 30 into a respective nip. The respective blanks 10 are then grasped in the roller gap, accelerated to the peripheral speed of the rollers and spaced apart from one another in accordance with the alignment of the roller pair. The pairs of rollers can be displaced transversely to their transport direction 74 for positioning on the blanks 10 . After the pairs of rollers, a conveyor belt is arranged that picks up and transports away the blanks 10 that are now laterally spaced apart from one another. The subordinate Conveyor belt preferably runs at a speed that is less than the peripheral speed of the pairs of rollers.

A device for treating, in particular depositing, substrates 01, in particular panels 10, can be connected to the downstream conveyor belt, which is described below in particular with regard to the 18 and 19 is described. The device comprises a circulating conveyor belt 29, 30, which conveys the substrates 01, in particular blanks 10, in at least one path, preferably in an imbricated stream, against at least one stop 77 for depositing the substrates 01 on a stack carrier 78. The stack carrier 78 can be a commercially available pallet or a system pallet such as is used in logistics systems in print shops or in the area of further processing. A transport device 79 is provided for handling, in particular moving, the stack support 78, with which the stack support 78 can be moved under the at least one stop 77 and/or the conveyor belt 29, 30 in such a way that the substrate sheets 01 or blanks conveyed by the conveyor belt 29. 30 move 10 on the stack carrier 78. The transport device 79 is designed for the vertical and horizontal displacement of the stack carrier 78 . The conveyor belt 29, 30 is associated with a device for forming a gap in the imbricated flow 83, which is preferably designed as a roller 83 or roller. The roller 83 or roller is arranged to be displaceable, for which purpose it is preferably mounted on levers at the end. Should a gap be formed in the shingled stream, e.g. B. the stack carrier 78 has to be relocated or replaced, the roller 83 or roller is relocated or pivoted until it is in surface contact with the conveyor belt 29, 30. If the transport belt 29, 30 continues to convey substrate sheets 01 as a result of its movement, these are backed up on the cylinder 83 or roller. The roller 83 or roller can be mounted in a fixed or rotatable manner and is preferably braked in the latter case.

The transport device 79 is designed to move the stack carrier 78 in one or more positions in which the stack carrier 78 and the at least a stop 77 and/or the stack carrier 78 and the conveyor belt 29, 30 overlap. A plurality of stops 77 are preferably arranged in groups next to one another on the conveyor belt 29, 30 transversely to the transport direction 74 of the substrate sheet 01 or the blank 10. More preferably, each group of stops 77 has either two side stops or two side stops and one back stop. Each group of stops preferably forms a kind of pocket, which is aligned on the conveyor belt 29, 30 by lateral positioning of the stops 77 on the stream(s) of substrate sheet 1 or panel 10.

The stops 77 are designed to be vertically movable. One or more drives are designed for the synchronous displacement of the stops 77 . The transport device 79 preferably has a drive which is designed for the discontinuous or continuous displacement of the stack carrier 78 . The transport device 79 is preferably designed to move the stack carrier 78 in and counter to the transport direction 74 of the transport belt 29, 30. More preferably, the transport device 79 is designed to move the stack carrier 78 in the transport direction 74 of the transport belt 29, 30 depending on the extension of the substrates 01 or panels 10 in the transport direction 74 of the transport belt 29, 30. More preferably, the transport device 79 is designed to implement a movement cycle that includes a first and at least one further movement of the stack carrier 78 in the transport direction 74 of the conveyor belt 29, 30, with the stack carrier 78 between its first and its at least one further movement with respect to the transport direction 74 of the conveyor belt 29, 30 is stationary.

Furthermore, a feed device 80 can be provided, with which at least one separating element 81 can be positioned on the substrates 01 carried by the stack carrier 78. The feed device 80 comprises a separating device, which separates the separating elements 81 from a stack 82 formed from a plurality of separating elements 81 . The separators 81 are preferably sheet-like materials that can be inserted between benefit stacks for spatial separation of the same from each other. The feed device 80 can be formed by a horizontally displaceable frame, the underside of which is associated with vertically displaceable suckers or other suitable fixing elements. It is also possible to design the feed device 80 with rigid suckers or other suitable fixing elements, provided that the frame allows a vertical movement for lifting a respective separating element 81 .

Preferred movement sequences, which the stack carrier 78 realizes through the action of the transport direction 74, are to be described below, in particular with regard to the Figures 20 to 32 be described as an example.

First, the stack carrier 78 is positioned by the transport device 79 in relation to the conveyor belt 29, 30 in such a way that, in relation to its vertical position, it has the smallest possible distance from its underside. In relation to its horizontal position, it is positioned in such a way that blanks 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited on the stack carrier 78. When the conveyor belt 29, 30 is circulating, substrate sheets 01 or blanks 10 are then conveyed onto the stack carrier 78 and are aligned laterally by the stops 77 and preferably also in the transport direction 74. As the process progresses, the stack of substrate sheet 01 or panel 10 grows, as in 21 shown. The stack carrier 78 is preferably lowered. The stops 77 can be lowered synchronously with the lowering movement of the stack carrier 78 . Alternatively, the stack carrier 78 can also be positioned from the start at such a vertical distance from the conveyor belt 29, 30 that it is able to receive a sufficient quantity of substrate sheets 01 or blanks 10 without vertical movement. In 21 only one stack is recognizable. In addition to this, several other adjacent stacks can be formed at the same time. When the stack of substrate sheet 01 or benefit 10 has reached a sufficient height, the Stops 77, if they were shifted with the stack carrier 78, shifted back vertically to their original position. The stack carrier 78 is displaced vertically into its starting position and horizontally by a distance that corresponds to the length of the substrate sheets 01 to be deposited plus a distance value. The chronological sequence of the shifting of the stack carrier 78 and the stops 77 is irrelevant, provided that collisions are avoided. The displacement preferably takes place synchronously. During the displacement of the stack carrier 78, the device for forming a gap in the imbricated stream 83 is activated, so that no substrate sheets 01 or blanks 10 are fed to the stack carrier 78 during this time. After the device for forming a gap in the imbricated stream 83 has been deactivated, the next stack of substrate sheet 01 or blank 10 can be formed on the stack carrier 78 ( 24 ).

The processes are then repeated, as described for the formation of the first stack of substrate sheets 01 or blanks 10, once or several times, until a further stack or further stacks of the desired height are formed, which, viewed in transport direction 74, are one behind the other and possibly also next to each other ( 25 ).

At this point in the process, the feed device 80 can be used. This grasps the uppermost separating element 81 of the stack 82 formed from separating elements 81 and transports it over the stack of substrate sheet 01 or blank 10 formed on stack carrier 78, where it is released and is deposited on the respective uppermost substrate sheet 01 or blank 10 ( 26 ). The surface of the separating sheet 81 subsequently takes the place of the surface of the stack carrier 78 and thus forms the new stack level.

In a next step, a single stack or a series of stacks of substrate sheets 01 or blanks 10 are formed on the new stack level. For this purpose, the stack carrier 78 is in relation to its vertical position of the transport device 79 such positioned so that the new stack level is below the release level of the conveyor belt 29, 30. In relation to its horizontal position, it is positioned in such a way that blanks 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited on the separating element 81 ( 28 ).

With conveyor belt 29, 30 revolving, substrate sheets 01 or blanks 10 are then conveyed onto separating element 81 and are aligned laterally by stops 77 and preferably also in transport direction 74. As the process progresses, the stack of substrate sheet 01 or panel 10 grows as in 29 shown.

The stack carrier 78 is preferably lowered. The stops 77 can be lowered synchronously with the lowering movement of the stack carrier 78 . Alternatively, the stack carrier 78 can also be positioned from the start at such a vertical distance from the conveyor belt 29, 30 that it is able to receive a sufficient quantity of substrate sheets 01 or blanks 10 without vertical movement. When the stack of substrate sheets 01 or panel 10 has reached a sufficient height, the stops 77, if they were moved with the stack carrier 78, are moved back vertically to their starting position. The stack carrier 78 is shifted vertically into the position it held at the beginning of the formation of the first stack on the separating element 81 and horizontally by a distance that corresponds to the length of the substrate sheets 01 to be deposited plus a distance value.

During the displacement of the stack carrier 78, the device for forming a gap in the imbricated stream 83 is activated, so that no substrate sheets 01 or blanks 10 are fed to the stack carrier 78 during this time. After the device for forming a gap in the imbricated stream 83 has been deactivated, the next stack of substrate sheet 01 or copy 10 can be formed on the separating element 81 ( 31 ).

Is there a sufficient number of stacks of substrate sheet 01 or blank 10 on the Formed stack carrier 78, the loaded stack carrier 78 is transported away and replaced by a new receptive stack carrier 78.

The sequence of the works of the sheet-fed press results from the technological requirements. One or more processing units 46 are preferably configured downstream of one or more printing units 06. If there are several printing units 06, these are usually equipped with different tools 116 from the group of cutting tools, punching tools, creasing tools, perforating tools or grooving tools. Likewise, one or more processing units 46 can precede one or more printing units 06. Alternatively, one or more processing units 46 can also be interposed between one or more printing units 06. The sheet-fed printing press preferably also includes one or more coating units, which are preferably located downstream of the printing units 06 or are connected to the processing units 46.

A substrate-processing machine, in particular a sheet-processing machine, which is not a printing press, can have the same design as the sheet-fed printing press described, minus the printing units 06.

The separating device 02 is formed downstream of the printing units 06 or the processing units 46. The separating device comprises a transport cylinder 03. The transport cylinder 03 is double-sized, ie it transports two substrate sheets 01 per revolution. However, the invention is not limited to a double-sized version of the transport cylinder 03. The invention is described below using a single-sized system. This description is also representative of the double-sized system or multi-sized system in analogous correspondence. In the area of the lateral surface of the transport cylinder 03, there is a sheet holding system for fixing the front edges of the sheet-like substrate 01, in particular a gripper system (in the case of a double-sized system, two Bow holding systems trained). The gripper system is preferably designed as a suction gripper system 17, also referred to as a suction system 17, and is supplied by air supply means. The suction gripper system 17 is designed to generate a suction area whose extent in the axial direction of the transport cylinder 03 is a multiple of its extent in the circumferential direction. The extension of the suction area of the suction gripper system 17 in the circumferential direction of the transport cylinder 03 is preferably less than 20 mm, more preferably less than 15 mm, more preferably less than 10 mm. The suction area can be formed by a continuous opening that extends across the width of the transport cylinder 03 or by a large number of suction openings located next to one another. The at least one suction opening is arranged to fix the front edge of the substrate 01 in such a way that, when the dressing 05 is fixed, it is spaced apart from the dressing 05 in the circumferential direction of the transport cylinder 03. The extension of the suction area in the axial direction of the transport cylinder 03 is advantageously designed to be adjustable. For this purpose, adjusting means 28, in particular in the form of shut-off valves, can be provided, in particular in the supply path for the suction air for the outer suction openings in relation to the center of the transport cylinder 03. The adjustability of the extension of the suction area has the advantage that suction air consumption is minimized. The transport cylinder 03 also preferably has means (in the case of a double-sized system, two fixing means are formed) for fixing an interchangeable elevator 05. The means for fixing are preferably designed as clamping grippers. A respective dressing 05 can be fixed with them at the rear edge and at the front edge. The means for fixing the front edge of the dressing 05 are preferably formed by the front edge clamping element 22 (also referred to as the clamping jaw) and the further clamping element 24 (also referred to as the overlay) which interacts correlatively with this to form a clamping gap. The other clamping element 24 is mounted firmly on the base body of the transport cylinder 03. The clamping element 22 is firmly connected to a lever 21 which is mounted on the base body of the transport cylinder 03 so that it can pivot about a pivot point 34 . The lever 21 is preferably a spring formed force accumulator 23 braced such that the clamping gap formed between the clamping element 22 and the further clamping element 24 closes. The spring 23 is designed as a compression spring and is supported with one end on the lever 21 and with its other end on the head of a screw screwed into the base body of the transport cylinder 03 . the 3 shows the front edge clamping gripper with the front edge of the elevator 05 fixed, ie in the closed state. the 4 shows the front edge clamping gripper with the front edge of the elevator 05 released, ie in the open state. The front edge of the clamping gripper is opened against the force of the spring 23 . The force required to open the front edge of the clamping gripper is preferably applied by an actuating element 23 which can be designed in particular as a pneumatic muscle 23 . The actuating element or the pneumatic muscle 23 preferably acts on a further lever 33, one end of which is supported on a fixed point of the transport cylinder 03. Under the force of the actuating element 23, which can be designed in particular as a pneumatic muscle 23, the further lever 33 can be pivoted about the aforementioned fixed point. If it is designed as a pneumatic muscle 23, compressed air is applied to it, under the effect of which it expands, with the further lever 33 being pivoted. The pivoting movement of the further lever 33 is limited by a wall formed on the transport cylinder 03 . The further lever 33 acts on a ball 35 which is formed between the further lever 33 and the lever 21 and shifts it. With the displacement of the ball 35, the lever 21 and with it the clamping element front edge 22 is also displaced. If the actuating element 23 is actuated in the opposite direction, or if the pneumatic muscle 23 is depressurized, ie switched without force, the force of the force accumulator 23, in particular of the spring 23, shifts the lever 21, the ball 35 and the further lever 33 back in the direction of their Starting position until the movement is limited by striking the front edge clamping element 22 against the other front edge clamping element 24 or the elevator 05. The rear edge of the elevator 05 can be fixed between a rear edge clamping element 47 and a further rear edge clamping element 48, the together form another clamping gap. The force required to close the trailing edge clamping gripper is applied by a rotatable tensioning shaft 50 which acts on the trailing edge clamping element 47 via a toggle lever 51 .

In order to tension elevator 05, at least one of the clamping grippers, ie the front edge clamping gripper or the rear edge clamping gripper, can be displaced in the circumferential direction of the transport cylinder. In the 3 and 4 the rear edge of the clamping gripper can be moved. In particular, the rear edge of the clamping gripper is mounted on a carriage that can be displaced in the circumferential direction of the transport cylinder 03. In addition to the rear edge clamping gripper, the carriage 49 preferably also carries the tensioning shaft 50 and the toggle lever 51. To tension the elevator 05, it is first fixed at both ends by the front edge clamping gripper and the rear edge clamping gripper. The carriage 49 is then moved clockwise, which is effected by a further actuating element 52, which can also be designed as a pneumatic muscle.

Irrespective of the type of design of the means for fixing the elevator 05, they preferably carry positioning pins or are preferably assigned positioning elements. The positioning pins or positioning elements can in particular be assigned directly to the further clamping element front edge 22 .

The transport cylinder 03 preferably has first and second openings 12, 13 which, when the dressing 05 is fixed, are at least partially covered by the openings that can be formed in the dressing 05. The openings 12,13 are connected to air supply means 14,15. In particular, first air supply means 14 are provided for supplying the first openings 12 with air and second air supply means 15 for supplying the second openings 13 with air. In the context below, air is understood to mean all forms of system air, ie in particular blown air or suction air which are suitable in particular for physical effects such as e.g. B. Force action exercise and which can be characterized by at least one of the parameters static pressure, dynamic pressure or volume flow. In particular, the chemical composition of the air or its moisture content is not important. Such air is generated in a manner known per se using compressors, compressors, vacuum pumps, suction pumps or similar components. The aforesaid air generators can be comprised of the first and second air supply means 14, 15 of the transport cylinder and in particular together with all the means that supply the air to the openings 12, 14 and/or control the supply form the air supply means 14, 15.

The first and the second openings 12, 13 can preferably be supplied with air independently of one another. Preferably, the air supply to either the first or the second openings 14, 15 or both openings 14, 15 is switchable. Switchability in this sense means, in particular, switching between suction air and blast air, it not being important which type of air supply is switched to which type.

The first and the second openings 12, 13 are formed in the lateral surface of the transport cylinder 03. The first and second openings 12, 13 are preferably arranged alternately in the circumferential direction of the transport cylinder 03 or in the axial direction of the transport cylinder 03. The first and/or the second openings 12, 13 are preferably designed in the form of grooves or holes. The arrangement of the first and second openings 12, 13 in the lateral surface of the transport cylinder 03 preferably results in a fine-meshed network of elements with which any openings formed in the elevator 05 can be supplied with air. The openings in the elevator 05 are arranged in accordance with the arrangement of the waste part or parts 09 on the one hand and the blank 10 on the other. For example, in the region of those first openings 12 that are formed in the region of the panel, openings can be formed in the elevator 05 are, while all second openings 13, which are formed in the area of benefit 10, no openings in the elevator 05 opposite. The same also applies analogously to the area of waste parts 09, in which case the second openings 13 are opposite openings in the elevator 05, while the first openings 12 are covered by closed areas of the elevator 05. Through these measures, blanks 10 and waste parts 09 can be treated differently or fixed on the lateral surface of the transport cylinder 03 or its elevator 05.

The details of the air supply to the first and second openings 12, 13 are particularly shown in FIGS figure 5 , 6 and 7 shown. The air supply means 14, 15 for supplying the first and second openings 12, 13 preferably comprise one or more rotary valves or rotary inlets. The rotary slides or rotary inlets are preferably formed on the end face of the transport cylinder 03 or are assigned to it. Two rotary slides or two rotary inlets are preferably formed on opposite end faces of the transport cylinder 03. At the in the figure 5 , 6 and 7 In the example shown, the rotary slide or the at least one rotary inlet includes a disk 18, which is assigned to one of the end faces of the transport cylinder 03. A plurality of groove-shaped recesses 19, 56, 57 are formed in the disk 18, which preferably extend in the shape of a segment of a circle, coaxially with the axis of rotation 16 of the transport cylinder 03. The recess 19 is supplied with air via a first supply socket 53 , the recess 56 via a second supply socket 54 and the recess 57 via a third supply socket 55 . The recesses 19, 56 and 57 are formed on the side of the disk 18 facing the transport cylinder 03. They extend in different radii in the shape of a segment of a circle, coaxially to the axis of rotation 16 of the transport cylinder 03. Each of the recesses 19, 56 and 57 does not have to be continuous in the circumferential direction of the disk 18 but rather can be perforated, so that several on the same radius viewed in the circumferential direction of the disk 18 successive recesses 19, 56 and 57 form. The recesses 19, 56 and 57 correspond with respect to their distance (radius) from the axis of rotation 16 of the transport cylinder 03 with openings 58 formed in the end face of the transport cylinder 03. Each of the openings 58 in the end face of the transport cylinder 03 communicates via additional lines either with a single or part of the first openings 12 or with a single or part of the second openings 13 in the lateral surface of the transport cylinder 03 or with the suction gripper system 17. Of course, this only applies as long as the respective opening is opposite the respective recess 19, 56 and 57, depending on the angular position of the transport cylinder 03. At the in 2 In the exemplary embodiment shown, the recesses 57 closest to the axis of rotation 16 of the transport cylinder 03 supply the suction gripper system 17, the recesses 56 adjacent to these supply the second openings 13, and the recesses 19 adjacent to these supply the first openings 12.

The disc 18 is stationary relative to the transport cylinder 03, which rotates about the axis of rotation 16 in the operating state. Due to the extension of the recesses 19, 56 and 57 in the circumferential direction of the transport cylinder 03, areas of suction or blown air are determined, which are formed on the lateral surface of the transport cylinder 03 in relation to the angle of rotation.

Superimposed on these effects, the areas of suction or blown air can also be determined by the type of air supply or by switching it on or off. Thus, the area supplied in its extension by the same air supply means 12 or 13 corresponding to the recesses 19, 56 can be shortened in that the air supply is switched off in relation to the angle. Likewise, an area supplied over its extent by the same air supply means 12 or 13 corresponding to the recesses 19, 56 can be divided into at least one suction area and at least one blowing area by switching the air supply between a suction air supply and a blown air supply. The suction area on the lateral surface of the transport cylinder 03 is used for fixing and the Blowing area for repelling blanks 10 or waste parts 09. It goes without saying that the air supply for the first openings 12 is preferably independent of the air supply for the second openings 13.

According to a preferred embodiment, the first and/or the second air supply means 14, 15 are designed to switch off the suction air supply or to switch between the suction air supply and the blower air supply depending on the angular position of the openings 12, 13 supplied in each case. The first air supply means 14 preferably switch the air supply to the first openings 12 off or from the suction air supply to the blowing air supply when the respective first openings 12 reach a first release point as a result of the transport cylinder 03 rotating about its axis of rotation 16 . More preferably, the second air supply means 15 switch the air supply to the second openings 13 off or from the suction air supply to the blowing air supply when the respective second openings 13 reach a second release point as a result of the transport cylinder 03 rotating about its axis of rotation 16.

The disk 18 is preferably connected to a frame via a torque support 20 and is rotatably mounted on the transport cylinder 03. The transport cylinder 03 is preferably rotatably mounted in the same frame to which the torque arm 20 is articulated.

In order to shift the areas of suction or blowing air, which are formed on the lateral surface of the transport cylinder 03 in relation to the angle of rotation, actuators for rotating the disk 18 can be provided.

In order to facilitate assembly, the disk 18 preferably has a recess which allows the disk 18 to be displaced radially in the sense of displacement for the purpose of replacement.

Instead of a disc 18, several discs 18 can be provided. In the case of several disks 18, the recesses 57 for supplying the suction pad system 17 are formed in one of the disks 18 and the recesses 19 and 56 for supplying the first and second openings 12, 13 are formed in the other disk 18.

The details of the supply of the suction gripper system 17 are shown in a preferred variant in 8 shown. In the exemplary embodiment shown, the disk 18 is used to supply the first and the second openings 12, 13 and to supply the suction pad system 17.

As an alternative to this, the disk 18 can also exclusively have a groove-shaped recess 57, which preferably extends in the shape of a segment of a circle, coaxially to the axis of rotation 16 of the transport cylinder 03. In this embodiment, too, the recess 57 is supplied with air by a third supply nozzle 55 . The recess 57 is formed on the side of the disk 18 facing the transport cylinder 03 . The recess 57 is preferably continuous or interrupted in the circumferential direction of the disc 18 so that several recesses 57 or sections of the recess 57 lying one behind the other viewed in the circumferential direction of the disc 18 are formed on the same radius. In terms of its distance (radius) from the axis of rotation 16 of the transport cylinder 03, the recess 57 corresponds to one or more openings 58 formed in the end face of the transport cylinder 03. The or each opening 58 communicates with the suction gripper system 17 via additional lines. Of course, this only applies as long as the respective opening 58 of the recess 57 depending on the angular position of the transport cylinder 03 opposite. In other words, the length and position of the angular range in which suction air is applied to the suction pad system 17, ie the suction pad system 17 develops a holding effect, is determined by the extent and position of the recesses 57.

It goes without saying that the air supply of the suction gripper system 17 is not limited to the described embodiment with disks 18 . The air supply of the suction pad system 17 can also be realized with other known embodiments of an air supply that can activate and deactivate the suction air applied to the suction pad system 17 in cycles sufficiently quickly.

The suction gripper system 17 is formed in the area of the lateral surface of the transport cylinder 03. The suction gripper system 17 is preferably assigned to the means for fixing the dressing 05 in place. In particular, the suction gripper system 17 can be mounted on the means for fixing the elevator 05. The means for fixing the dressing 05 in place, and thus also the suction gripper system 17, is preferably mounted so that it can move, in particular pivot. The suction gripper system 17 can in particular be assigned to the front edge 22 of the clamping element. It is also advantageous to arrange the suction pad system 17 together with the clamping element 22 on the lever 21 .

According to a preferred embodiment, a stripping cylinder 04 is arranged adjacent to the transport cylinder 03 . Like the transport cylinder 03, the stripping cylinder 04 is rotatably mounted. The stripping cylinder 04 is used to break out waste parts 09 or blanks 10. The stripping cylinder 04 preferably has third openings 32. Third air supply means are provided for supplying the third openings 32 with air.

Like the transport cylinder 03, the stripping cylinder 04 can also be double-sized or single-sized. In the case of a double-sized design of the stripping cylinder 04, its circumference or diameter corresponds to the circumference or diameter of a double-sized transport cylinder 03. The stripping cylinder 04 is preferably designed to be single-sized. In terms of its structure, the stripping cylinder 04 preferably resembles the transport cylinder 03 in many respects, see above that to describe the nature of the stripping cylinder 04, reference is made to the statements on the nature of the transport cylinder 03. This applies in particular to all assemblies of the transport cylinder 03 or the stripping cylinder 04 for which no structural differences or absence are expressly pointed out. The nature of the stripping cylinder 04 is described below using a single-sized system. This description is also representative of the double-sized system or multi-sized system in analogous correspondence. In contrast to transport cylinder 03, stripping cylinder 04 does not include a sheet holding system for fixing the front edges of sheet-type substrate 01.

Like the transport cylinder 03, the stripping cylinder 04 preferably has means for fixing a replaceable packing 05. The means for fixing are preferably designed as clamping grippers. A respective dressing 05 can be fixed with them at the rear edge and at the front edge. The means for fixing the front edge of the dressing 05 are preferably formed by the front edge clamping element 22 and the further clamping element 24 interacting correlatively with this to form a clamping gap. The front edge clamping element 22 is mounted on the base body of the stripping cylinder 04 . The further clamping element 24 can in particular be formed as a leaf spring assembly. Adjacent to the further clamping element 24 is arranged a control element 25 preferably designed as a pneumatic muscle. The control element is preferably connected to an air supply, with which an overpressure can be applied to the control element 25 . When overpressure is applied, the actuating element 25 expands, bearing against the further clamping element 24 and deforming it. As a result of the deformation, in particular the bending of the further clamping element 24, its extent changes in the direction of the clamping element front edge 22. By applying an overpressure z. g. in the form of compressed air on the actuating element 25, the gap formed between the front edge of the clamping element 22 and the further clamping element 24 can be enlarged and reduced when the overpressure on the actuating element 25 is switched off, which corresponds to the binding of the elevator 05. the 10 shows the clamping gripper of the stripping cylinder 04 front edge with the front edge of the elevator 05 fixed, ie in the closed state.

The rear edge of the dressing 05 can be fixed between a rear edge clamping element 47 and a further rear edge clamping element 48, which together form a further clamping gap. The force required to close the trailing edge clamping gripper is applied by a rotatable tensioning shaft 50 which acts on the trailing edge clamping element 47 via a toggle lever 51 .

At least one of the clamping grippers, i.e. the front edge clamping gripper or the rear edge clamping gripper, can be displaced in the circumferential direction of the stripping cylinder 04 in order to tension the dressing 05. In the 10 the rear edge of the clamping gripper can be moved. In particular, the rear edge of the clamping gripper is mounted on a carriage 49 that can be displaced in the circumferential direction of the stripping cylinder 04. In addition to the rear edge clamping gripper, the carriage 49 preferably also carries the tensioning shaft 50 and the toggle lever 51. To tension the elevator 05, it is first fixed at both ends by the front edge clamping gripper and the rear edge clamping gripper. Subsequently, the carriage 49 is displaced counterclockwise, which is effected by a further actuating element 52, which can also be designed as a pneumatic muscle.

Irrespective of the type of design of the means for fixing the elevator 05, they preferably carry positioning pins or are preferably assigned positioning elements. The positioning pins or positioning elements can in particular be assigned directly to the further clamping element front edge 22 .

It goes without saying that the elements described for fixing the front edge and the elements for fixing the rear edge can also be designed in a different way. So it turns out to be an alternative to the formation of non-positive acting elements is also advantageous if the elements for fixing the front edge and/or the elements for fixing the rear edge are designed for the form-fitting fixing of elevators 05. In this case, in particular, hook-shaped or claw-shaped retaining elements can be formed that correspond to recesses that are formed in the elevator 05 or engage in retaining rails that are firmly connected to the elevator 05.

The front edge of the clamping gripper or the rear edge of the clamping gripper are preferably mounted in a channel of the stripping cylinder 04, which can be covered by a channel cover.

The stripping cylinder 04 preferably has third openings 32 which, when the dressing 05 is fixed, are at least partially covered by the openings that can be formed in the dressing 05. The third openings 32 are connected to third air supply means. In the following context, air is understood to mean all forms of system air, i. H. in particular blown air or suction air, which are particularly suitable physical effect such. B. to exert force and which can be identified by at least one of the parameters static pressure, dynamic pressure or flow rate. Such air is generated in a manner known per se using compressors, compressors, vacuum pumps, suction pumps or similar components.

The third openings 32 can be supplied with suction air. The air supply is preferably designed to be switchable. Switchability in this sense means, in particular, switching between suction air and blast air, it not being important which type of air supply is switched to which type.

The third openings 32 are formed in the lateral surface of the stripping cylinder 04. The third openings 32 are preferably in the form of grooves or holes. Through The arrangement of third openings 32 in the lateral surface of the stripping cylinder 04 preferably results in a fine-meshed network of elements with which any openings formed in the packing 05 can be supplied with air. The openings in the elevator 05 are arranged in accordance with the arrangement of the waste part or parts 09 on the one hand or blank 10 on the other. For example, openings can be formed in elevator 05 in the area of those third openings 32 that are formed in the area of the panel. This proves to be advantageous if the stripping cylinder 04 is to be used to transport the panel 10.

If the demolition cylinder 04 is to be used to transport waste parts 09, openings in the lift 05 are preferably formed in the area of those third openings 32 that are formed in the area of waste parts 09.

Through these measures, blanks 10 or waste parts 09 can be treated differently or fixed on the lateral surface of the transport cylinder 03 or its packing 05. The release of the blanks 10 or waste parts 09 can be assisted by applying blown air to the third openings 32 .

The details of the air supply to the third openings 32 are not shown separately and are described below with reference to the design of the air supply means 14, 15 on the transport cylinder 03. The air supply means for supplying the third openings 32 preferably comprise a rotary valve or a rotary inlet. The rotary slide or the rotary inlets are preferably formed on the end face of the transport cylinder 03 or assigned to it. The rotary slide or the at least one rotary inlet preferably includes a disk 18, which is assigned to one of the end faces of the stripping cylinder 04. A recess X is formed in the disk 18, which preferably extends in the shape of a segment of a circle, coaxially to the axis of rotation of the stripping cylinder 04. The recess is supplied with air via a fourth supply nozzle 53 . The recess is formed on the side of the disk 18 facing the stripping cylinder 04. The recesses are not continuous in the circumferential direction of the disc 18 but rather can be perforated, so that several recesses lying one behind the other are formed on the same radius viewed in the circumferential direction of the disc 18 . In terms of its distance (radius) from the axis of rotation of the stripping cylinder 04, each recess corresponds to openings 58 formed in the end face of the stripping cylinder 04. Each of the openings 58 in the end face of the transport cylinder 03 communicates via additional lines either with a single or part or all of the third openings 32 in the lateral surface of the stripping cylinder 04. Of course, this only applies as long as the respective opening 58 is opposite the respective recess depending on the angular position of the stripping cylinder 04.

The disc 18 is stationary relative to the stripping cylinder 04, which rotates about its central axis during operation. The extent of the recesses in the circumferential direction of the stripping cylinder 04 determines areas of suction or blast air that are formed on the lateral surface of the stripping cylinder 04 in relation to the angle of rotation.

Superimposed on these effects, the areas of suction or blown air can also be determined by the type of air supply or by switching it on or off. In this way, the area supplied by the third air supply means corresponding to the recess can be shortened in that the air supply is switched off in relation to the angle. Likewise, an area supplied in its extent by the third air supply means corresponding to the recesses can be divided into at least one suction area and at least one blowing area by switching the air supply between a suction air supply and a blown air supply. The suction area on the lateral surface of the stripping cylinder 04 is used for fixing and the blowing area for removing blanks 10 or waste parts 09.

According to a preferred embodiment, the third air supply means are designed to switch off the suction air supply or to switch between the suction air supply and the blower air supply depending on the angular position of the third openings 32 supplied in each case. The third air supply means preferably switch the air supply to the third openings 32 off or from suction air supply to blown air supply when the respective third openings 32 reach a third release point as a result of the rotation of the stripping cylinder 04 about its central axis.

The disk 18 is preferably connected to a frame via a torque support 20 and is rotatably mounted on the stripping cylinder 04 . The stripping cylinder 04 is preferably rotatably mounted in the same frame to which the torque arm 20 is articulated.

In order to shift the areas of suction or blown air that are formed on the outer surface of the stripping cylinder 04 in relation to the angle of rotation, actuators for rotating the disk 18 can be provided.

In order to facilitate assembly, the disk 18 preferably has a recess which allows the disk 18 to be displaced radially in the sense of displacement for the purpose of replacement. The recess has an extent that is greater than the diameter of a pin of the stripping cylinder 04 in the region of the stripping cylinder 04 in which the disk 18 is associated with it.

The stripping cylinder 04 and the transport cylinder 03 each carry a lift 05, preferably for treating substrates 01, in particular for separating or stripping processed substrates 01, i.e. substrates 01 with ridges or perforations that have been cut or cut through, into at least one waste part 09 and at least one blank 10. During separation or breaking out are remaining holding webs or Material connections or intentionally not completely cut through material connections, in particular fibers or fiber bundles in the area of cutting lines between waste part 09 and at least one benefit 10 torn. For this purpose, one of the linings 05 can be designed as a female mold and the other lining 05 as a male mold. The patrix has a base plane and areas that are raised relative to the base plane. The raised areas act on the substrate 01 and form tools 116. The die has a base plane and areas that are recessed relative to the base plane or other recesses. The die and the die are arranged on the transport cylinder 03 or the stripping cylinder 04 in such a way that the raised areas of the die are opposite the recessed areas or the further recesses of the die. The patrix forms a kind of counterpart to the matrix. The matrix is arranged either on the transport cylinder 03 or the stripping cylinder 04 and the patrix on the other cylinder. The other cylinder in this sense is the cylinder that cooperates with the cylinder carrying the matrix (transport cylinder 03 or stripping cylinder 04). The matrix is preferably arranged on the transport cylinder 03 and the patrix on the stripping cylinder. The male and female tool pair described above preferably differs from male and female tool pairs as they are used for cutting or perforating, e.g. B. on the processing cylinders upstream of the separating device 02. The structural design of the patrix is determined by its function of only pressing the elements to be separated or broken out into the recessed areas or the further recesses of the matrix. Accordingly, the raised areas of the patrix can also have significantly smaller extensions than the corresponding depressed areas or further recesses of the matrix. In particular, a flexographic printing plate can be used as the patrix.

In an alternative embodiment, the patrix does not have any areas that are raised relative to the base plane, but rather a base plane that is raised overall. In this case is the patrix is provided with an elastic coating at least on the side facing the matrix or is formed from an elastic material.

When separating or breaking out, waste parts 09 and blanks 10 are moved relative to one another, with residual webs or individual fibers or fiber bundles being torn in the area of the cutting lines. For this purpose, either the waste parts 09 or the blanks 10 are preferably pressed by the male mold into the recessed areas or the other recesses of the female mold. If a male mold with an elastic surface is used, the waste parts 09 are pressed into the recessed areas or the further recesses of the female mold, with the surface of the male mold expanding at these points, while in areas of the surface outside the recesses or further recesses in the the die, the substrate is pressed against the surface of the die.

According to a further preferred embodiment, the transport cylinder 03 is not assigned a stripping cylinder 04, with the waste parts 09 and blanks 10 also being moved relative to one another in this embodiment and residual webs or individual fibers or fiber bundles being torn in the area of the cutting lines. The separating device 02 is preferably designed in such a way that it only acts on the side of the processed substrate 01 that faces the transport cylinder 03, while the substrate 01 is being transported on the transport cylinder 03. In a preferred embodiment, the separating device 02 is formed from raised areas and areas of the surface of the transport cylinder 03 that are recessed relative to the raised areas. First openings 12 , which can be operatively connected to first air supply means 14 , are more preferably assigned to the recessed areas. The first air supply means 14 are preferably designed to supply suction air. More preferably, the lateral surface of the transport cylinder 03 is assigned an interchangeable dressing 05, with the raised areas of the surface of the transport cylinder 03 being covered by the dressing 05 and the recessed areas of the surface of the transport cylinder 03 are formed by the outer surface of the transport cylinder 03 in the area of openings formed in the packing 05. Second openings 13, which are in operative connection with second air supply means 15, can be formed in the raised areas and/or the recessed areas of the surface of the transport cylinder 03. Furthermore, the first and/or the second air supply means 14, 15 can be switchable between a suction air supply and a blown air supply.

In order to implement the relative movement of the waste parts 09 and blanks 10 relative to one another, the transport cylinder 03 can be assigned a lift 05, which is designed in particular in the manner of a matrix and has recessed areas or further openings. In the area of the recessed areas or other openings, a negative pressure is applied via the first and/or second openings 12, 13, which moves the waste parts 09 and blanks 10 relative to one another, i.e. in particular pulls the waste parts 09 into the recessed areas or the other openings , while the panels 10 are supported on the base plane of the die. As an alternative to this, it can also be provided that the blanks 10 are pulled into the recessed areas or the further openings, while the waste parts 09 are supported on the base plane of the die. In other words, the separating process is preferably effected solely by the force of the negative pressure present in the recessed areas or other openings or the suction air on the sides of blanks 10 or waste parts 09 facing transport cylinder 03. In this case, openings are preferably arranged in the area of the recessed areas. These ensure that the negative pressure present at the first and/or second openings 12, 13 can spread to the side of the blank 10 or waste parts 09 that faces the transport cylinder 03.

When separating the substrate sheets 01 into waste parts 09 and copies 10, problems arise, particularly in environments with low humidity, which are caused by unwanted electrostatic charging of the waste parts 09 and/or copies 10 and/or the surfaces of the transport cylinder 03 and/or stripping cylinder 04 are caused. As a result of the electrostatic charges, waste parts 09 and/or blanks 10 adhere to the surfaces of transport cylinder 03 and/or stripping cylinder 04. In these cases, the effect of gravity is usually not sufficient to remove waste parts 09 and/or blanks 10 from the cylinder surface or to be removed from the tools 116 or tool parts fixed on the cylinder surfaces, in particular male and female molds.

According to a further embodiment, which serves in particular to avoid problems caused by electrostatic charges, provision is made for a separating device 02 to be formed, which comprises a transport cylinder 03 and a stripping cylinder 04 assigned to it, with an antistatic device 95 being assigned to the transport cylinder 03 and/or the stripping cylinder 04 is ( 9 and Figure 49 , where at the Figure 49 the transport cylinder 03 is shown as an example). The transport cylinder 03 preferably has means for fixing an interchangeable dressing 05 in place, as well as openings 12, 13 which, when the dressing 05 is fixed, are at least partially covered by openings that can be formed in the dressing 05, with air supply means 14, 15 for supplying the openings 12, 13 with air are provided. The antistatic device 95 preferably includes at least one electrode connected to at least one high voltage source. The high voltage source can be a positive or a negative high voltage source. Alternatively, the high-voltage source can be switched between an operating mode as a positive and an operating mode as a negative high-voltage source. The high-voltage sources can be connected via a controller to a sensor that detects the voltage present on the surfaces of transport cylinder 03 and/or stripping cylinder 04 or the tools 116 or tool parts attached to them. The controller is preferably designed to activate the positive or negative high-voltage source on a case-by-case basis or to switch the switchable high-voltage source depending on the sign of the applied voltage. The controller can also use the value of the pending 12 Voltage as a system parameter process and control at least one high-voltage source depending on this system parameter. The high-voltage sources described preferably supply a pulsed or an unpulsed DC voltage.

The electrode of the antistatic device 95 preferably extends in the axial direction of the stripping cylinder 04 over its length and/or in the axial direction of the transport cylinder 03 over its length.

According to a further development, the antistatic device 95 comprises a brush, the brush comprising a cylindrical or a strip-shaped base body, which is designed in particular to be electrically conductive. Bristles 105 are assigned to the base body. In the case of a cylindrical configuration, the base body can be rotatably mounted.

In this case, the bristles 105 are preferably arranged in a uniformly distributed manner on the lateral surface of the base body. If the base body is in the form of a strip, it is fixed in at least one operating position in relation to the surface of the cylinder to which it is assigned (transport cylinder 03 or stripping cylinder 04).

The bristles 105 are preferably formed from an electrically conductive material such as metal. A carbon compound can also be used as the material of the bristles 105 . The bristles 105 are more preferably formed from intertwined fibers or fiber bundles. These can be arranged in a row next to each other. Preferably, several of the described rows of intertwined fibers or fiber bundles are arranged one behind the other, viewed in the direction of rotation of the transport cylinder 03 or stripping cylinder 04.

As an alternative to the assignment of bristles 105, a cloth 105 be assigned, which has electrically conductive fibers. The fibers can be woven into the cloth 105 or attached to the cloth 105, e.g. B. be connected by an adhesion promoter. In the further developments in which bristles 105 or a cloth 105 are assigned to the base body, the bristles 105 or cloth 105 form the electrode or are connected to the electrode.

The embodiments of antistatic devices 95, which are equipped with bristles 105 or a cloth 105, are arranged in relation to the transport cylinder 03 or stripping cylinder 04 in such a way that they touch the lateral surface of the respective cylinder. A device is preferably provided with which the antistatic device 95 can be switched between an operating position in which the bristles 105 or the cloth 105 touch the lateral surface of the respective cylinder and a parking position in which the bristles 105 or the cloth 105 do not touch the lateral surface of the respective cylinder touch, is relocatable.

In addition or as an alternative to this, it is preferred in such developments that the antistatic device 95 comprises a blowing device that generates a volume flow of a gaseous medium ionized by at least one electrode in the direction of the lateral surface of the transport cylinder 03 and/or the lateral surface of the stripping cylinder 04.

As an alternative or in addition to forming the separating device 02 with an antistatic device 95, the tools 116 or tool parts used, e.g. B. female and male mold, and/or the cylinder surfaces of transport cylinder 03 and/or a stripping cylinder 04 assigned to it are designed to be antistatic, in particular with electrically conductive materials.

According to another preferred embodiment, with or without a stripping cylinder 04, a circulating conveyor belt 29 is assigned to the transport cylinder 03, as shown in particular in FIG 11 or 12 . is evident. The conveyor belt 29 is preferably arranged above the transport cylinder 03. The conveyor belt 29 is assigned to partially wrap around the transport cylinder 03, preferably forming a wrap angle. As an alternative to this, the conveyor belt 29 can also be assigned to the transport cylinder 03, forming a tangent point 36. More preferably, the tangent point 36 is formed in the 12 o'clock position of the transport cylinder 03. The extent of the conveyor belt 29 is determined by the arrangement of deflection rollers. The conveyor belt 29 preferably has a horizontally extending transport area 37 . The conveyor belt 29 can in particular be designed as a suction belt. More preferably, at least in the transport area 37 , suction air is applied to the transport belt 29 . It follows from this that the conveyor belt 29 can be designed for the suspended transport of blanks and/or waste parts 10, 09.

The conveyor belt 29 has the particular function of taking over the processed substrate sheet 01, waste parts 09 or blanks 10 at the tangent point 36 or in the area where the conveyor belt 29 wraps around it, in order to take over the transport cylinder 03 from it and transport it further.

Another transport system can be connected to the conveyor belt 29 , for example in the form of a further conveyor belt 30 . An overlapping area is preferably formed between the conveyor belt 29 and the additional conveyor belt 30, in which functionally processed substrate sheets 01 or blanks 10 and/or waste parts 09 can be transferred from the conveyor belt 29 to the additional conveyor belt 30. More preferably, the further conveyor belt 30 is designed for the horizontal transport of blanks and/or waste parts 10, 09.

It goes without saying that instead of the additional conveyor belt 30, another suitable transport system can also be embodied that accepts processed substrate sheets 01 or blanks 10 and/or waste parts 09 from the conveyor belt 29.

Instead of the further conveyor belt 30, a container for receiving waste parts can also be arranged under the conveyor belt 30.

In addition to the conveyor belt 29, another transport system 76 can also be attached directly to the transport cylinder 03, i. H. forming a transfer area or transfer point between the transport cylinder 03 and the further transport system for processed substrate sheets 01 or blanks 10 and/or waste parts 09. This further transport system 76 is preferably designed as a sheet-guiding cylinder or sheet-guiding drum or chain conveyor system with gripper bridges or conveyor belt.

The operation of an embodiment as preferably defined by the 11 or 12 . illustrated can be described as follows. The illustrated embodiment of the device for treating substrates is preferably part of a sheet-fed printing press. The sheet-fed printing press can include one or more printing units. More preferred are the in 11 or 12 . The embodiment shown has two processing cylinders, between which the substrate 01 can be inserted, with the substrate 01 being processed upstream as it passes through tool parts from the group of cutting tools, stamping tools, creasing tools and perforating tools that are effective in the cylinder gap. One of the processing cylinders is in 11 or 12 . shown as a semicircle. The processing cylinder is preferably designed as a sheet transport cylinder and has a sheet holding system. The sheet transport cylinder transfers a processed substrate sheet 01 to the transport cylinder 03 at the tangent point A between the transport cylinder 03 and the sheet transport cylinder upstream. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 01, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 03, holds the processed substrate sheet, in particular the cut substrate sheet 01 takes over. the Substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries an elevator 05. The elevator 05 has openings and is provided with indentations at the points at which it acts on the blank 10 . On the one hand, openings are made in the area of the panel 10 at the points in the elevator 05 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 05, that is to say they are closed. On the other hand, openings are also made in the area of the waste parts 09 at the points in the elevator 05 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 09 being covered by the elevator 05, i.e. being closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 03 or exactly at the tangent point A, the first air supply means 14 applies a vacuum to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 03 or on the elevator 05 fixed. As a result of the further rotation of the transport cylinder 03, the blanks 10 fixed by the vacuum and the waste parts 09 reach the tangent point B, which is formed between the transport cylinder 03 and the stripping cylinder 04. At the tangent point B, the raised areas of the elevator 05, which is arranged on the stripping cylinder 04, make contact with the surfaces of the waste parts 09 and press the waste parts 09 into the depressions of the elevator 05 fixed on the transport cylinder 03. The residual webs that the waste parts 09 connect to the frame or to good parts 10, torn. Preferably at tangent point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09, which fixes the waste parts 09 to the lateral surface of the transport cylinder 03 or to the elevator 05. As an alternative to this, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09 at the target point A or immediately thereafter. When the respective benefits 10 reach the transfer point or transfer area C between the transport cylinder 03 and the conveyor belt 29, the first Air supply means 14 preferably disabled. The negative pressure in the area of the first openings 12 is no longer present and the blanks 10 are no longer fixed and thus released. As a result of the negative pressure preferably applied to the conveyor belt 29, the blanks 10 are lifted from the transport cylinder 03 in the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away hanging from it. The transfer of the blanks 10 from the transport cylinder 03 to the transport belt 29 can be assisted by applying excess pressure to the first openings 12. The supply of the first openings 12 is preferably switched over from negative pressure to positive pressure when the first openings reach the transfer point or transfer area C in the area of the respective panel 10 . The blanks 10 can preferably be transported away with the additional conveyor belt 30 . For this purpose, the conveyor belt 29 conveys the blanks 10 to the further conveyor belt 30 and transfers the blanks 10 to the further conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated, so that the blanks under the effect of gravity or by additional suction on the another conveyor belt 30 fixed on this and transported away by this. When the waste parts 09 reach the release point D, the negative pressure present at the second openings 13 in the region of the waste parts 09 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. As a result, the waste parts 09 are released or the waste parts 09 are actively repelled, which can be picked up by a waste container. In the area of release point D, the front edge of the substrate sheet 01 is preferably also released by the gripper system 17 in addition to the waste parts 09.

The further operation of an embodiment as preferably by the 11 or 12 . illustrated can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 01 to the transport cylinder 03 at the tangent point A between the transport cylinder 03 and the upstream sheet transport cylinder processed substrate sheet 01, while the gripper system, in particular the suction gripper system 17 of transport cylinder 03, takes over the processed, in particular cut, substrate sheet 01. The substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries a packing 05. The packing 05 has openings and has indentations at the points at which it acts on the board 10 Mistake. On the one hand, openings are made in the area of the panel 10 at the points in the elevator 05 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 05, that is to say they are closed. On the other hand, openings are also made in the area of the waste parts 09 at the points in the elevator 05 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 09 being covered by the elevator 05, i.e. being closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 03 or exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 03 or on the elevator 05 fixed. As a result of the further rotation of the transport cylinder 03, the blanks 10 fixed by the vacuum and the waste parts 09 reach the tangent point B, which is formed between the transport cylinder 03 and the stripping cylinder 04. At the tangent point B, the raised areas of the elevator 05, which is arranged on the stripping cylinder 04, come into contact with the surfaces of the waste parts 09 and press the waste parts 09 into the depressions of the elevator 05 fixed on the transport cylinder 03. The residual webs that the waste parts 09 connect to the frame or to good parts 10, torn. The elevator 05 fixed on the stripping cylinder 04 has openings that correspond to the third openings 32 of the stripping cylinder 04 . The openings are formed in the area of the dressing 05, in which the latter is not raised or interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 04 reach the tangent point B and at the tangent point B face a respective panel 10, a negative pressure is applied to them. As a result of this negative pressure, a force is developed that lifts the blanks 10 off the surface of the transport cylinder 03 . The negative pressure at the third openings 32 of the stripping cylinder 04 is deactivated as soon as they have left the area of the tangent point B again or a few angular degrees, in particular 10 degrees, thereafter. Preferably, the negative pressure present at the first openings 12 is deactivated when the respective first openings 12 are in the area of the tangent point B. This ensures that the respective panel 10 is briefly lifted from the surface of the transport cylinder 03 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 04, i.e. for a few angular degrees, in particular 10 degrees of the rotary movement of the transport cylinder 03. This measure additionally supports the separation of blanks 10 and waste parts 09, since these are actively moved in different directions, at least for a short time. Preferably at tangent point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09, which fixes the waste parts 09 to the lateral surface of the transport cylinder 03 or to the elevator 05. As an alternative to this, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09 at the target point A or immediately thereafter. When the respective blanks 10 reach the transfer point or transfer area C between the transport cylinder 03 and the transport belt 29, the first air supply means 14 are preferably deactivated. The negative pressure in the area of the first openings 12 is no longer present and the blanks 10 are no longer fixed and thus released. As a result of the negative pressure preferably applied to the conveyor belt 29, the blanks 10 are lifted from the transport cylinder 03 in the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away hanging from it. The transfer of the blanks 10 from the transport cylinder 03 to the transport belt 29 can be assisted by applying excess pressure to the first openings 12. The supply of the first openings 12 is from negative pressure Overpressure is preferably switched over when the first openings in the area of the respective benefit 10 reach the transfer point or transfer area C. The blanks 10 can preferably be transported away with the additional conveyor belt 30 . For this purpose, the conveyor belt 29 conveys the blanks 10 to the further conveyor belt 30 and transfers the blanks 10 to the further conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated, so that the blanks under the effect of gravity or by additional suction on the another conveyor belt 30 fixed on this and transported away by this. When the waste parts 09 reach the release point D, the negative pressure present at the second openings 13 in the region of the waste parts 09 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. As a result, the waste parts 09 are released or the waste parts 09 are actively repelled, which can be picked up by a waste container. In the area of release point D, the front edge of the substrate sheet 01 is preferably also released by the gripper system 17 in addition to the waste parts 09.

Another mode of operation of an embodiment as preferably defined by the 11 or 12 . illustrated relates to whole-sheet processing or whole-sheet inspection and will be described below. The sheet transport cylinder transfers a processed substrate sheet 01 to the transport cylinder 03 at the tangent point A between the transport cylinder 03 and the sheet transport cylinder upstream. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 01, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 03, holds the processed substrate sheet, in particular the cut substrate sheet 01 takes over. The substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries an elevator 05. The elevator 05 has openings. The openings are introduced at the points in the elevator 05 at which the first and/or second openings 12, 13 are formed. If the first and/or second openings 12, 13 as a result of the rotation of the transport cylinder 03 have passed the tangent point A or exactly at the tangent point A, the first and/or second air supply means 14, 15 apply a negative pressure to the first and/or second openings 12, 13 applied, which fixes only the panel 10 or only the waste parts 09 or the panel 10 and the waste parts 09 on the outer surface of the transport cylinder 03 or on the elevator 05. As a result of the further rotation of the transport cylinder 03, the blanks 10 and the waste parts 09 pass the tangent point B. The waste parts 09 or the blanks with other elements do not come into contact at the tangent point B. When the respective blanks 10 and the respective waste parts 09 reach the transfer point or transfer area C between the transport cylinder 03 and the transport belt 29, the first and/or second air supply means 14, 15 are preferably deactivated. The negative pressure in the area of the first and/or openings 12, 13 is no longer present and the blanks 10 and the waste parts 09 are no longer fixed and are thus released. The fixing of the front edges of the substrate sheets 01 by the gripper system 17 is also canceled at the transfer point or transfer area C. As a result of the negative pressure preferably applied to the conveyor belt 29, the blanks 10 and the waste parts 09 and the frames of the substrate sheets 01, including the front edges of the substrate sheets 01, which are still connected to one another by the remaining webs (complete sheets), are removed from the transport cylinder 03 at the transfer point or transfer area C lifted, fixed to the underside of the conveyor belt 29 and transported away from this hanging. The transfer of blanks 10 and waste parts 09 and the frames of substrate sheets 01, including the front edges of substrate sheets 01, as a whole sheet from transport cylinder 03 to transport belt 29 can be assisted by applying overpressure to the first and/or second openings 12, 13. The supply of the first and/or second openings 12, 13 is preferably switched over from negative pressure to positive pressure when the first and/or second openings 12, 13 reach the transfer point or transfer area C.

The complete sheets can preferably be transported away with the additional conveyor belt 30 . For this purpose, the conveyor belt 29 conveys the complete sheets to the further conveyor belt 30 and transfers the complete sheets to the further conveyor belt 30. For the transfer, the negative pressure applied to the transport belt 29 is preferably deactivated, so that the complete sheets are subjected to the effect of gravity or by an additional suction effect on the further conveyor belt 30 are fixed on this and transported away from this.

According to another preferred embodiment with a stripping cylinder 04, a circulating conveyor belt 29 is assigned to the stripping cylinder, as shown in particular in FIG 13 is evident. The conveyor belt 29 is preferably arranged above the transport cylinder 03. The conveyor belt 29 is assigned to the stripping cylinder 04, preferably forming a transfer point 38 or transfer area. More preferably, the conveyor belt 29 is arranged so that it partially wraps around the stripping cylinder 04, forming a wrap angle. The transfer point 38 or the transfer area is particularly preferably formed in the 8 o'clock position of the stripping cylinder 04 and the stripping cylinder 04 is assigned to the transport cylinder 03 in the 12 o'clock position of the transport cylinder 03. The extent of the conveyor belt 29 is determined by the arrangement of deflection rollers. The conveyor belt 29 preferably has a first transport area 39, which extends at least approximately tangentially to the stripping cylinder 04. More preferably, the first transport area 39 is inclined at an angle of between 30 and 60 degrees to the horizontal. The conveyor belt 29 preferably has a second transport area 40 which runs at least approximately horizontally, in particular exactly horizontally. In particular, the conveyor belt 29 is a suction belt and the first transport area 39 is an area in which suction air is present on the conveyor belt 29 . The conveyor belt 29 has in particular the function of taking over the processed substrate sheets 01, waste parts 09 or blanks 10 at the transfer point 38 or transfer area between the conveyor belt 29 and the stripping cylinder 04 from the stripping cylinder 04 and transport further. Another transport system can be connected to the conveyor belt 29 , for example in the form of a further conveyor belt 30 . An overlapping area is preferably formed between the conveyor belt 29 and the additional conveyor belt 30, in which functionally processed substrate sheets 01 or blanks 10 and/or waste parts 09 can be transferred from the conveyor belt 29 to the additional conveyor belt 30. It goes without saying that instead of the additional conveyor belt 30, another suitable transport system can also be embodied that accepts processed substrate sheets 01 or blanks 10 and/or waste parts 09 from the conveyor belt 29. In addition to the conveyor belt 29, a further transport system 76 can also be assigned directly to the transport cylinder 03, i.e. forming a transfer area or transfer point between the transport cylinder 03 and the further transport system 76 for processed substrate sheets 01 or copies 10 and/or waste parts 09. This further transport system 76 is preferably designed as a sheet-guiding cylinder or sheet-guiding drum or chain conveyor system with gripper bridges or conveyor belt. The stripping cylinder 05 preferably has third openings 32 and third air supply means for supplying the third openings 32 with air. The third air supply means can preferably be switched between a suction air supply and a blown air supply. In particular, the third air supply means are designed to switch between suction air supply and blown air supply depending on the angular position of the third openings 32 supplied in each case. More preferably, the third air supply means are designed to switch the air supply of the third openings 32 from suction air supply to blowing air supply when the respective third openings 32 reach a third release point as a result of the stripping cylinder 04 rotating about its axis of rotation, in particular the transfer point or transfer area between stripping cylinder 04 and conveyor belt 29 The third openings 32 can be in the form of grooves or holes. The third air supply means preferably comprise a rotary slide or a rotary inlet, with the at least one rotary slide or the at least one rotary inlet on the end face of the Stripping cylinder 04 can be formed. Like the transport cylinder 03, the stripping cylinder 04 preferably has means for fixing a replaceable packing 05. The means for fixing are preferably designed as clamping grippers. A respective elevator 05 can be fixed with them at the rear edge and at the front edge. The means for fixing the front edge of the dressing 05 are preferably formed by the front edge clamping element 22 and the further clamping element 24 interacting correlatively with this to form a clamping gap. The front edge clamping element 22 is mounted on the base body of the stripping cylinder 04 . The further clamping element 24 can in particular be formed as a leaf spring assembly. Adjacent to the further clamping element 24 is arranged a control element 25 preferably designed as a pneumatic muscle. The control element is preferably connected to an air supply, with which an overpressure can be applied to the control element 25 . The rear edge of the dressing 05 can be fixed between a rear edge clamping element 47 and a further rear edge clamping element 48, which together form a further clamping gap. The force required to close the trailing edge clamping gripper is applied by a rotatable tensioning shaft 50 which acts on the trailing edge clamping element 47 via a toggle lever 51 .

Further preferred details of the stripping cylinder 04 are in 10 and the associated description, to which reference is made in connection with the exemplary embodiment described. An elevator 05 with openings is preferably fixed on the stripping cylinder 04 . The openings in the lining 05 of the stripping cylinder 04 correspond to the third openings 32 of the opening cylinder 04. The openings are preferably formed in the region of the lining 05, in which it is not raised and interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 04 reach the tangent point B and are opposite a respective panel 10 at the tangent point B, a vacuum is applied to them. As a result of this negative pressure, the blanks 10 are lifted off the surface of the transport cylinder 03 power unfolds.

A preferred mode of operation of an embodiment as preferably defined by the 13 illustrated can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 01 to the transport cylinder 03 at the tangent point A between the transport cylinder 03 and the sheet transport cylinder upstream. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 01, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 03, holds the processed substrate sheet, in particular the cut substrate sheet 01 takes over. The substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries a packing 05. The packing 05 has openings and has indentations at the points at which it acts on the board 10 Mistake. Perforations are preferably made on the one hand in the area of the panel 10 at the points in the lining 05 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the lining 05, ie closed. On the other hand, openings are preferably also made in the area of the waste parts 09 at the points in the elevator 05 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 09 being covered by the elevator 05, i.e. being closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 03 or exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 03 or on the elevator 05 fixed. As a result of the further rotation of the transport cylinder 03, the blanks 10 fixed by the vacuum and the waste parts 09 reach the tangent point B, which is formed between the transport cylinder 03 and the stripping cylinder 04. At the tangent point B, the raised areas of the lift 05, which is arranged on the stripping cylinder 04, make contact Surfaces of the waste parts 09 and press the waste parts 09 into the recesses of the elevator 05 fixed on the transport cylinder 03. The residual webs that connect the waste parts 09 to the frame or to good parts 10 are torn. The elevator 05 fixed on the stripping cylinder 04 has openings that correspond to the third openings 32 of the stripping cylinder 04 . The openings are preferably formed in the area of the dressing 05 in which the latter is not raised or interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 04 reach the tangent point B and are opposite a respective panel 10 at the tangent point B or directly in front of it, a vacuum is applied to them. As a result of this negative pressure, a force is developed that lifts the blanks 10 off the surface of the transport cylinder 03 . The negative pressure present at the first openings 12 of the transport cylinder 03 is preferably deactivated when the respective first openings 12 are in the area of the tangent point B. This ensures that the respective panel 10 is lifted off the surface of the transport cylinder 03 under the effect of the negative pressure at the third openings 32 of the stripping cylinder. The negative pressure applied to the second openings 13 is preferably maintained when the respective second openings 13 pass the tangent point B. As a result, the waste parts 09 are held on the surface of the transport cylinder 04 and transported past the tangent point B, while the blanks 10 are transferred at the tangent point B from the transport cylinder 03 to the stripping cylinder 04. As a result of its rotation, the stripping cylinder 04 transports the blanks 10 fixed by the vacuum further in the direction of the conveyor belt 29 until they reach the transfer point or transfer area E of the stripping cylinder 04 and the conveyor belt 29 . In the transfer point or transfer area E of the stripping cylinder 04 and the conveyor belt 29, a suction effect is preferably exerted on the side of the blank 10 facing away from the stripping cylinder 04 by the conveyor belt 29, which is preferably designed as a suction belt. In addition, when the respective third openings 32 reach the transfer point or transfer area E, the negative pressure applied to them is deactivated. An overpressure can preferably be built up at the third openings 32 following the deactivation of the underpressure. The respective blanks 10 are transferred from the stripping cylinder 04 to the conveyor belt 29 in the transfer point or transfer area E by the force effects described. The conveyor belt 29 runs on deflection rollers, at least one of which is driven, and transports the blanks 10 preferably to a stacking device or storage device, not shown. After the transfer point or transfer area E has been passed through the third openings 32, the negative pressure applied to them can be deactivated. The deactivation ends at the latest when the third openings 32 enter the tangent point B again. Preferably at tangent point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09, which fixes the waste parts 09 to the lateral surface of the transport cylinder 03 or to the elevator 05. As an alternative to this, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09 at the target point A or immediately thereafter. When the waste parts 09 reach the release point D, the negative pressure present at the second openings 13 in the region of the waste parts 09 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. As a result, the waste parts 09 are released or the waste parts 09 are actively repelled, which can be picked up by a waste container. In the area of release point D, the front edge of the substrate sheet 01 is preferably also released by the gripper system 17 in addition to the waste parts 09.

Another mode of operation of an embodiment as preferably defined by the 13 . illustrated relates to whole-sheet processing or whole-sheet inspection and will be described below. The sheet transport cylinder transfers a processed substrate sheet 01 to transport cylinder 03 at the tangent point A between transport cylinder 03 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 01, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 03 takes over the processed, in particular cut, substrate sheet 01. The substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries an elevator 05. The elevator 05 has openings. The openings are introduced at the points in the elevator 05 at which the first and/or second openings 12, 13 are formed. When the first and/or second openings 12, 13 have passed the tangent point A or exactly at the tangent point A as a result of the rotation of the transport cylinder 03, the first and/or second air supply means 14, 15 at the first and/or second openings 12, 13, a negative pressure is applied, which fixes only the blanks 10 or only the waste parts 09 or the blanks 10 and the waste parts 09 on the lateral surface of the transport cylinder 03 or on the elevator 05. When the respective blanks 10 and the respective waste parts 09 reach the tangent point B as a result of the further rotation of the transport cylinder 03, the first and/or second air supply means 14, 15 are preferably deactivated. The negative pressure in the area of the first and/or openings 12, 13 is no longer present and the blanks 10 and the waste parts 09 are no longer fixed and are thus released. The fixing of the front edges of the substrate sheet 01 by the gripper system 17 is also canceled at the tangent point B. When the third openings 32 of the stripping cylinder 04 reach the tangent point B and are opposite a respective panel 10 at the tangent point B or directly in front of it, a vacuum is applied to them. As a result of this negative pressure, a force is developed that lifts the blanks 10 off the surface of the transport cylinder 03 . The negative pressure present at the first and/or second openings 12, 13 of the transport cylinder 03 is preferably deactivated when the respective first and/or second openings 12, 13 are in the area of the tangent point B. As a result of the negative pressure that is preferably present at the third openings 32, the blanks 10 and the waste parts 09 and the frames of the substrate sheets 01, including the front edges of the substrate sheets 01, which are still connected to one another by the remaining webs (complete sheet), are separated from the transport cylinder at the tangent point B 03 and transferred to the stripping cylinder 04. The transfer of blanks 10 and waste parts 09 and the frames of substrate sheets 01, including the front edges of substrate sheets 01, as a whole sheet from transport cylinder 03 to stripping cylinder 04 can be assisted by applying overpressure to the first and/or second openings 12, 13. The supply of the first and/or second openings 12, 13 is preferably switched over from negative pressure to positive pressure when the first and/or second openings 12, 13 reach the tangent point B. As a result of its rotation, the stripping cylinder 04 transports the whole sheets fixed by the vacuum further in the direction of the conveyor belt 29 until they reach the transfer point or transfer area E of the stripping cylinder 04 and the transport belt 29. At the transfer point or transfer area E of stripping cylinder 04 and conveyor belt 29, a suction effect is preferably exerted on the side of the whole sheet facing away from stripping cylinder 04 by conveyor belt 29, which is preferably designed as a suction belt. In addition, when the respective third openings 32 reach the transfer point or transfer area E, the negative pressure applied to them is deactivated. An overpressure can preferably be built up at the third openings 32 following the deactivation of the underpressure. The full sheets are transferred from the stripping cylinder 04 to the conveyor belt 29 at the transfer point or transfer area E as a result of the force effects described. The conveyor belt 29 runs on deflection rollers, at least one of which is driven, and preferably transports the complete sheets to a stacking device or storage device, not shown. After the transfer point or transfer area E has been passed through the third openings 32, the negative pressure applied to them can be deactivated. The deactivation ends at the latest when the third openings 32 enter the tangent point B again.

According to another preferred embodiment, with or without a stripping cylinder 04, a peeling device 31 (also called a peeling device) is assigned to the transport cylinder 03, as shown in particular in FIG 14 is evident. The peeling device 31 has preferably a bearing surface that extends in the direction of a virtual tangent applied to the transport cylinder 03. The support surface can be aligned horizontally. The peeling device 31 is further preferably associated with a circulating conveyor belt 29, which can be designed as a suction belt circulating over deflection rollers. The peeling device 31 is preferably assigned to the transport cylinder 03 in its 12 o'clock position or viewed in the direction of rotation of the transport cylinder 03, directly adjacent to its 12 o'clock position. The conveyor belt 29 preferably has a transport area 37 which is horizontal or inclined at an angle of less than 10 degrees with respect to the horizontal. According to a preferred embodiment, the support surface formed on the peeling device 31 and the transport area 37 lie in one and the same virtual plane. More preferably, the support surface and the transport area 37 extend in the direction of a virtual tangent applied to the transport cylinder 03.

The transport cylinder 03 and the optional stripping cylinder 04 can be designed according to those embodiments of the transport cylinder 03 and stripping cylinder 04, as they are used in particular in connection with the objects according to FIG Figures 9 to 13 have already been described.

The peeling device 31 has the particular function of lifting processed substrate sheets 01, waste parts 09 or blanks 10 with the aid of the peeling device 31 from the surface of the transport cylinder 03 or the surface of the elevator 05 assigned to it and feeding them to the conveyor belt 29, which transports them away.

Another transport system can be connected to the conveyor belt 29 , for example in the form of a further conveyor belt 30 . An overlapping area is preferably formed between the conveyor belt 29 and the additional conveyor belt 30, in which processed substrate sheets 01 or blanks 10 and/or waste parts 09 can be transferred from the conveyor belt 29 to the additional conveyor belt 30.

It goes without saying that, instead of the additional conveyor belt 30, another suitable transport system can also be embodied that accepts processed substrate sheets 01 or blanks 10 and/or waste parts 09 from the conveyor belt 29.

Instead of the further conveyor belt 30, a container for receiving waste parts 09 can also be arranged under the conveyor belt 29.

In addition to the conveyor belt 29, another transport system 76 can also be attached directly to the transport cylinder 03, i. H. forming a transfer area or transfer point between the transport cylinder 03 and the further transport system 76 for processed substrate sheets 01 or blanks 10 and/or waste parts 09. This further transport system 76 is preferably designed as a sheet-guiding cylinder or sheet-guiding drum or chain conveyor system with gripper bridges or conveyor belt.

The operation of an embodiment as preferably defined by the 14 illustrated can be described as follows. The illustrated embodiment of the device for treating substrates 01 is preferably part of a sheet-fed printing press. The sheet-fed printing press can include one or more printing units 06. More preferred are the in 14 . In the embodiment shown, two processing cylinders are arranged upstream, between which the substrate 01 can be inserted, with the substrate 01 being processed as it passes through tool parts from the group of cutting tools, stamping tools, creasing tools, and perforating tools that are effective in the cylinder gap. One of the processing cylinders is in 14 . shown as a semicircle. The processing cylinder is preferably designed as a sheet transport cylinder and has a sheet holding system. The sheet transport cylinder transfers a processed substrate sheet 01 to the transport cylinder 03 at the tangent point A between the transport cylinder 03 and the upstream sheet transport cylinder of the sheet transport cylinder releases the processed substrate sheet 01, while the gripper system 17, in particular the suction gripper system 17, of the transport cylinder 03 takes over the processed, in particular cut, substrate sheet 01. The substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries a dressing 05. The dressing 05 has openings and has indentations at the points at which it acts on the blank 10 Mistake. On the one hand, openings are made in the area of the panel 10 at the points in the elevator 05 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 05, that is to say they are closed. On the other hand, openings are also made in the area of the waste parts 09 at the points in the elevator 05 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 09 being covered by the elevator 05, i.e. being closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 03 or exactly at the tangent point A, the first air supply means 14 applies a vacuum to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 03 or on the elevator 05 fixed. As a result of the further rotation of the transport cylinder 03, the blanks 10 fixed by the vacuum and the waste parts 09 reach the tangent point B, which is formed between the transport cylinder 03 and the stripping cylinder 04. At the tangent point B, the raised areas of the elevator 05, which is arranged on the stripping cylinder 04, make contact with the surfaces of the waste parts 09 and press the waste parts 09 into the depressions of the elevator 05 fixed on the transport cylinder 03. The residual webs that the waste parts 09 connect with the frame or with good parts (panel) 10, torn. Preferably at tangent point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09, which fixes the waste parts 09 to the lateral surface of the transport cylinder 03 or to the elevator 05. As an alternative to this, the negative pressure can be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09 can also be applied at tangent point A or immediately thereafter. As a result of the rotation of the transport cylinder 03, the blanks 10 and the waste parts 09 are transported past the target point B until they finally reach the transfer point F between the transport cylinder 03 and the peeling device 31. Before the respective blanks 10 reach the transfer point F between the transport cylinder 03 and the peeling device 31, the first air supply means 14 of the transport cylinder 03 are switched over from a suction air supply to a blown air supply. The negative pressure in the area of the first openings 12 is reduced, so that the blanks 10 are no longer fixed and, to the extent that the positive pressure builds up at the first openings 12, are pushed off the surface of the transport cylinder 03 or its packing 05. As a result, at least the front edges of the blanks 10, viewed in the direction of rotation of the transport cylinder 03, protrude beyond the peeling device 31 in the radial direction of the transport cylinder 03. The peeling device 31 aims into the gap formed between the front edges of the blanks 10 and the surface of the transport cylinder 03 or its elevator 05. As a result of the rotation of the transport cylinder 03, the blanks 10 are pushed onto the support surface of the peeling device 31 until they enter the detection area of the conveyor belt 29, which causes the benefit 10 to be transported away. Unlike the first openings 12, the negative pressure applied to the second openings 13 is maintained by the second air supply means 15 when the second openings 13 pass the tangent point B until they reach the release point D. When the release point D is reached, the negative pressure present at the second openings 13 is deactivated. In a preferred embodiment, an overpressure can also be applied to the second openings 13 when the second openings 13 reach the area of the release point D. With the method steps mentioned, not only is the fixing of the waste parts 09 terminated when the release point D is reached, but the lifting of the waste parts 09 is preferably supported with pneumatic means in addition to the force of gravity. In the area of the release point D, in addition to the waste parts 09 preferably also the front edge of the substrate sheet 01 is released from the gripper system 17.

Another mode of operation of an embodiment as preferably defined by the 14 illustrated relates to whole-sheet processing or whole-sheet inspection and will be described below. The sheet transport cylinder transfers a processed substrate sheet 01 to transport cylinder 03 at the tangent point A between transport cylinder 03 and the upstream sheet transport cylinder cut substrate sheet 01 takes over. The substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries an elevator 05. The elevator 05 has openings. The openings are introduced at the points in the elevator 05 at which the first and/or second openings 12, 13 are formed. When the first and/or second openings 12, 13 have passed the tangent point A or are located exactly at the tangent point A as a result of the rotation of the transport cylinder 03, the first and/or second air supply means 14, 15 at the first and/or second openings 12, 13, a negative pressure is applied, which fixes only the blanks 10 or only the waste parts 09 or the blanks 10 and the waste parts 09 on the lateral surface of the transport cylinder 03 or on the elevator 05. As a result of the further rotation of the transport cylinder 03, the blanks 10 and the waste parts 09 pass the tangent point B. The waste parts 09 or the blanks 10 do not come into contact with other elements at the tangent point B. The stripping cylinder 04 is separated from the transport cylinder 03. When the respective blanks 10 and the respective waste parts 09 reach the transfer point F between the transport cylinder 03 and the peeling-off device 31, the first and/or second air supply means 14, 15 are deactivated or preferably switched to blown air supply switched. The negative pressure in the area of the first and/or second openings 12, 13 is no longer present and the blanks 10 and the waste parts 09 and the frames of the substrate sheets 01, including the front edges of the substrate sheets 01, which are still connected to one another by the residual webs (full sheets ), are no longer fixed and are thus released at the transfer point F and preferably lifted off the surface of the transport cylinder 03 or the elevator 05 in a targeted manner. The fixing of the front edges of the substrate sheets 01 by the gripper system 17 is also canceled at the transfer point or transfer area C. As a result of the rotation of the transport cylinder 03, the whole sheets are then pushed over the support surface of the peeling device 31 until they reach the effective range of the transport belt 29, from which they are transported away.

The operation of an embodiment as preferably defined by the 15 illustrated can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 01 to transport cylinder 03 at the tangent point A between transport cylinder 03 and the upstream sheet transport cylinder cut substrate sheet 01 takes over. The substrate sheet 01 preferably comprises an edge and waste parts 09 and blanks 10 connected to it by so-called residual webs. The transport cylinder 03 carries a dressing 05. The dressing 05 has openings and has indentations at the points at which it acts on the blank 10 Mistake. On the one hand, openings are made in the area of the panel 10 at the points in the elevator 05 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 05, that is to say they are closed. On the other hand, openings are also made in the area of the waste parts 09 at the points in the elevator 05 at which second openings 13 are formed, the first openings 12 being in the area of the waste parts 09 covered by the elevator 05, that is closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 03 or are located exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which vacuums the blanks 10 on the lateral surface of the transport cylinder 03 or fixed to elevator 05. As a result of the further rotation of the transport cylinder 03, the blanks 10 fixed by the vacuum and the waste parts 09 reach the tangent point B, which is formed between the transport cylinder 03 and the stripping cylinder 04. At the tangent point B, the raised areas of the elevator 05, which is arranged on the stripping cylinder 04, make contact with the surfaces of the waste parts 09 and press the waste parts 09 into the depressions of the elevator 05 fixed on the transport cylinder 03. The residual webs that the waste parts 09 connect to the frame or to good parts 10, torn. The elevator 05 fixed on the stripping cylinder 04 has openings that correspond to the third openings 32 of the stripping cylinder 04 . The openings are formed in the area of the dressing 05, in which the latter is not raised or interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 04 reach the tangent point B and are opposite a respective panel 10 at the tangent point B, a vacuum is applied to them. As a result of this negative pressure, a force is developed that lifts the blanks 10 off the surface of the transport cylinder 03 . The negative pressure at the third openings 32 of the stripping cylinder 04 is deactivated as soon as they have left the area of the tangent point B again or a few angular degrees, in particular 10 degrees, thereafter. Preferably, the negative pressure present at the first openings 12 is deactivated when the respective first openings 12 are in the area of the tangent point B. This ensures that the respective blank 10 is briefly lifted from the surface of the transport cylinder 03 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 04, i.e. for a few angular degrees, in particular 10 degrees of the rotary movement of the transport cylinder 03. By this measure, the separation of Benefits 10 and waste parts 09 are additionally supported, since these are actively moved in different directions, at least for a short time. Preferably at tangent point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09, which fixes the waste parts 09 to the lateral surface of the transport cylinder 03 or to the elevator 05. As an alternative to this, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 09 at the target point A or immediately thereafter. As a result of the rotation of the transport cylinder 03, the blanks 10 and the waste parts 09 are transported past the target point B until they finally reach the transfer point F between the transport cylinder 03 and the peeling device 31. Before the respective blanks 10 reach the transfer point F between the transport cylinder 03 and the peeling device 31, the first air supply means 14 of the transport cylinder 03 are switched over from a suction air supply to a blown air supply. The negative pressure in the area of the first openings 12 is reduced, so that the blanks 10 are no longer fixed and, to the extent that the positive pressure builds up at the first openings 12, are pushed off the surface of the transport cylinder 03 or its packing 05. As a result, at least the front edges of the blanks 10, viewed in the direction of rotation of the transport cylinder 03, protrude beyond the peeling device 31 in the radial direction of the transport cylinder 03. The peeling device 31 aims into the gap formed between the front edges of the blanks 10 and the surface of the transport cylinder 03 or its elevator 05. As a result of the rotation of the transport cylinder 03, the blanks 10 are pushed onto the support surface of the peeling device 31 until they are in the Get into the detection area of the conveyor belt 29, which causes the benefit 10 to be transported away. Unlike the first openings 12, the negative pressure applied to the second openings 13 is maintained by the second air supply means 15 when the second openings 13 pass the tangent point B until they reach the release point D. When the release point D is reached, the negative pressure present at the second openings 13 is reduced disabled. In a preferred embodiment, an overpressure can also be applied to the second openings 13 when the second openings 13 reach the area of the release point D. With the method steps mentioned, not only is the fixing of the waste parts 09 terminated when the release point D is reached, but the lifting of the waste parts 09 is preferably supported with pneumatic means in addition to the force of gravity. In the area of the release point D, the front edge of the substrate sheet 01 is preferably also released by the gripper system 17 in addition to the waste parts 09.

Instead of the conveyor belt 29, a further transport system 76 can also be assigned directly to the transport cylinder 03, i.e. forming a transfer area or transfer point between the transport cylinder 03 and the further transport system 76 for processed substrate sheets 01 or copies 10 and/or waste parts 09. This additional transport system 76 is preferably designed as a sheet-guiding cylinder or sheet-guiding drum or sheet-guiding system, in particular a chain conveyor system with gripper bridges, or a conveyor belt. An embodiment with a chain conveyor system with gripper bridges as part of the delivery 99 of a sheet-fed printing press is in 17 shown.

The chain conveyor system contains traction means which are moved via drive and deflection means and which drive gripping devices, in particular gripper bridges, for conveying the substrate. The gripping devices have fixing elements for taking over and fixing the sheet-like substrates 01. In particular, clamping and/or suction grippers can be used as fixing elements for gripping the edges of the substrate. In developments that are not shown, additional gripping devices are provided for the rear edges of the substrate. The sheet conveyor system designed here as a chain conveyor system contains chains that are laid over chain wheels and are driven by them and are guided in laterally arranged guide rails (not shown), on which gripper bridges for transporting the substrates 01 are arranged. The gripper bridges pick up the substrates 01 in Transport direction promoted to the display stack stored on, for example, a pallet or some other type of transport document. The gripper bridges preferably contain leading edge clamping grippers which have gripper fingers which interact with gripper bridges and which are arranged at a distance from one another on a gripper shaft and can be controlled by the latter.

A substrate guide device and, for example, a dryer are provided in the delivery 99 for safe transport of the substrates 01 held by the gripper bridges. The substrate guide device has substrate guide plates facing the gripper bridges, which are provided with blast air nozzles and extend over the width of the machine. Blower boxes are arranged under the substrate guide plate, via which the blown air nozzles are supplied with blown air, so that a supporting air cushion is formed between the substrate guide plate and the substrates 01 transported by the gripper bridges. In order to be able to control heating of the substrate guide plate in the area of the dryer, a coolant circuit can be integrated. In order to prevent the substrates 01 from sticking together on the delivery stack, a release agent application device, in particular a powder device, preferably combined with a device for sucking off the powder, is preferably provided in the area of the delivery 99.

In front of the delivery stack there is a braking device, not designated further, for decelerating the substrates 01 released by the gripper bridges. The braking device can contain rotating suction rings and/or circulating suction belts or can be designed as a follow-up gripper system. The substrates 01, decelerated by the braking device, come into contact with front stops and are placed in an aligned manner on the delivery stack. The delivery stack is preferably lowered by a stack lifting drive by the thickness of the deposited substrate, so that the surface of the stack always assumes an approximately constant level.

Another mode of operation of an embodiment, as preferably defined by the 17 illustrated will be described below. The substrates 01 to be processed lie as a stack of substrate sheets in feeder 07 and are separated from this stack of substrate sheets and fed one after the other either to one or more printing units 06 and printed in them or, if no printing units 06 are provided, fed directly to processing unit 46. The substrate sheets 01 are processed in processing unit 46. To do this, the substrate sheets 01 are inserted one after the other into a cylinder gap formed between two processing cylinders and punched in such a way that a punched sheet (processed substrate sheet 01) is produced from each substrate sheet 01, which consists of at least one panel 10 and at least a waste part 09 and a frame enclosing it, the panel 10, waste part 09 and frame adhering to one another via material connections that have not been completely severed. The processing cylinders can be designed as tool-carrying punching cylinders or embodied by impression cylinders 41 and blanket cylinders 43 of a sheet-fed printing press. The substrate sheets 01 that have now been processed are preferably transferred to the transport cylinder 03 by a sheet transport cylinder at the tangent point A between the transport cylinder 03 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 01, while the gripper system 17, in particular the suction gripper system 17, of the transport cylinder 03 takes over the processed, in particular cut, substrate sheet 01. The transport cylinder 03 preferably carries an elevator 05. The elevator 05 has openings. The openings are introduced at the points in elevator 05 at which openings 12, 13, in particular first and/or second openings 12, 13, are formed. Preferably when the openings 12, 13 have passed the tangent point A as a result of the rotation of the transport cylinder 03 or are located exactly at the tangent point A, the first and/or second air supply means 14, 15 apply a negative pressure to the openings 12, 13, which Blank 10 or only the waste parts 09 or the blank 10 and the waste parts 09 are fixed to the lateral surface of the transport cylinder 03 or to the elevator 05. As a result of the further rotation of the transport cylinder 03, the waste parts 09, which are preferably fixed by the vacuum, reach the tangent point B, which is formed between the transport cylinder 03 and the stripping cylinder 04. At the tangent point B, the raised areas of the dressing 05, which is arranged on the stripping cylinder 04, come into contact with the surfaces of the waste parts 09 and press the waste parts 09 into the depressions of the dressing 05 fixed on the transport cylinder 03. The material connections that have not been completely severed, the connect the waste parts 09 to the frame or panel 10, separated, i.e. torn. It goes without saying that the raised areas of the dressing 05 can alternatively also be in the form of recessed areas. In this case, the corresponding areas of the stripping cylinder 04 are preferably raised. The decisive factor is that the raised or recessed areas on the transport cylinder 03 and on a stripping cylinder 04 assigned to it are designed in such a way that the material connections that are not completely severed are separated, i.e. torn.

As a result of the rotation of the transport cylinder 03, the blanks 10 and the waste parts 09 are transported past the target point B until they finally reach the transfer point F between the transport cylinder 03 and the further transport system 76. At the transfer point F, the frames with the blanks 10 adhering to them exclusively via incompletely severed material connections are transferred to a stacker, in particular a delivery 99, more preferably a respective gripper bridge of the delivery 99, from which they are preferably transported to a stack carrier and stacked.

When the waste parts 09 reach the transfer point F between the transport cylinder 03 and the further transport system 76, the first and/or second air supply means 14, 15 of the transport cylinder 03 maintain the supply of suction air to the first and/or second openings 12, 13. Only when the waste parts 09 reach the release point D is the suction air supply to the first and/or second Openings 12, 13 repealed or preferably switched to blown air supply, so that the waste parts 09 release or are preferably actively repelled.

In connection with the separating processes between the transport cylinder 03 and the stripping cylinder 04, it has proven to be advantageous in preferred embodiments to only remove selected material connections that are not completely severed and to maintain others in a targeted manner in order to provide the necessary for the further transport of the frame and the panel 10 associated with it to maintain stability. Accordingly, it is preferably provided that between transport cylinder 03 and stripping cylinder 04, the incompletely severed material connections between the rear frame part in the transport direction of the frame and panel 10 are removed and the incompletely severed material connections between the front frame part in the transport direction of the frame and panel 10 are maintained. Furthermore, the incompletely severed material connections between the frame parts that are on the side in the transport direction of the frame and the panel 10 can also be eliminated.

More preferably, the incompletely severed material connections between a plurality of blanks 10 are maintained between the transport cylinder 03 and the stripping cylinder 04.

The method described above can be carried out in particular using one of the described embodiments of the device for treating substrates 01, in particular using the in 17 illustrated and in relation to 17 described device are carried out.

Another preferred embodiment is in particular in 16 shown and will be further described below. The embodiment includes a transport cylinder 03, which in its basic structure corresponds to that in FIG 2 illustrated transport cylinder 03 may correspond, so hereby in particular the 2 and the associated parts of the description and in addition to the 3 to 8 including associated parts of the description. A stripping cylinder 04 can be assigned to the transport cylinder 03, which in its basic structure corresponds to that in FIG 10 illustrated stripping cylinder 04 may correspond, so that hereby on the 10 and the associated parts of the description.

The transport cylinder 03 and/or the stripping cylinder 04 preferably have means for fixing an exchangeable packing 05 in place.

In the case of a preferred embodiment with a transport cylinder 03 without an associated stripping cylinder 04, the means for feeding the replaceable packing 05 are associated with the transport cylinder 03. In the case of a further preferred embodiment with a transport cylinder 03 with an associated stripping cylinder 04, the means for feeding the replaceable packing 05 are assigned to the transport cylinder 03 or the stripping cylinder 04 or both to the transport cylinder 03 and to the stripping cylinder 04.

The means for feeding the interchangeable dressing 05, if they are assigned to the transport cylinder 03, comprise a pressing means 60 that can be selectively attached to and removed from the transport cylinder 03, in particular pivoted on and off, and if they are assigned to the stripping cylinder 04, a pressing means 60 that is attached to the stripping cylinder 04 pressing means 61 that can be selectively switched on and off, in particular that can be swiveled on and off. The pressing means 60, 61 is preferably designed as a roller or cylinder. The roller or roller can have an elastic surface, in particular a rubber surface. The roller or roller is rotatably mounted and can extend over the entire width of the respective cylinder (transport cylinder 03 or stripping cylinder 4) or only over part of its width. Likewise, the roller can be formed by a plurality of rollers which are aligned with one another with respect to their axis of rotation. The roll or cylinder is free movable or, in a preferred embodiment, motor-driven. More preferably, the roller or cylinder can also be assigned a motor that drives and/or brakes the roller or cylinder. A suitable braking device, for example in the form of a friction brake, can also be assigned to the roller.

The roll or roller is preferably mounted on a displaceable pressure arm 62, 63, which is assigned a drive means 64, 65, preferably in the form of a linear drive 64, 65, more preferably in the form of a pneumatic cylinder 64, 65 or electric linear motor. The pressing arm 62, 63 can be pivoted about a pivot point.

The means for feeding the interchangeable dressing 05 preferably comprise a guide roller 66, 67 and/or a guide rail 68, 69. More preferably, the at least one guide roller 66, 67 is assigned to a movably mounted guard 70, 71. The protection 70, 71 can be assigned a sensor that detects its position.

The means for supplying the interchangeable elevator 05 can also include a store 72, 73 that is able to accommodate multiple elevators 05. The store 72, 73 is designed to store at least one elevator 05, while at least one other elevator 05 is arranged on the transport cylinder 03 or the stripping cylinder 04, with which the elevator 05 stored can be exchanged in alternation. The store 72, 73 is preferably able to accommodate a lift 05 that has been removed or is to be removed in addition to a lift 05 that is to be supplied. The store 72, 73 preferably has different storage locations for an elevator 05 to be fed in and an elevator 05 to be removed.

The means for feeding the interchangeable dressing 05 can also have a device for pre-positioning, in particular positioning pins. the Device for pre-positioning is preferably assigned to memory 72, 73.

To arrange a dressing 05 on the transport cylinder 03, the transport cylinder 03 is first rotated into a receiving position provided for receiving the dressing 05. The transport cylinder 03 can be rotated using an individual drive assigned to it or via a gear train which drives the transport cylinder 03 to other cylinders and into which a main drive drives. In the receiving position, the means for fixing the front edge of the interchangeable dressing 05 are at least approximately opposite the store 72. The lower edge of the elevator 05 to be fed (which corresponds to the front edge when it is fixed on the transport cylinder 03) stands on a store 72 designed as a rail 72, preferably an angle rail. According to a preferred embodiment, the store 72 has positioning means, for example in the form of positioning pins assigned to the positioning recesses in the elevator 05 correspond. If positioning pins are formed, the positioning recesses in the packing 05 are opposite the positioning pins and the packing 05 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the elevator 05, the bottom edge of the elevator 05 is released from the rail 72 by the rail 72 being pivoted or twisted by a motor or the front edge of the elevator 05 being lifted off the rail 72 manually. The guard 70, which is pivotably mounted and which preferably carries a guide roller 66 at the end, is pivoted manually or by motor, resulting in an access opening through which the elevator 05 can be fed to the means for fixing the elevator 05. As soon as the front edge of the elevator 05 has passed the access opening provided by the guard 70 and the guide roller 66, the guard 70 is pivoted back to its starting position manually or by a motor so that the guide roller 66 contacts the elevator 05 and thus the elevator 05 on its way is guided to the nip formed between the jaw 22 and the cuff 24. The feed of the elevator 05 is preferably carried out by the action of Gravity or alternatively motor driven or manual. When the front edge of the dressing 05 has reached the clamping gap, the lever 21 is pivoted and the front edge of the dressing 05 is thus fixed between the clamping jaw 22 and the stop 24 . The transport cylinder 03 is then rotated counterclockwise by a motor. When the front edge of the dressing 05 has moved under the pressure roller 60 as a result of the rotation of the transport cylinder 03, the linear drive 64 is actuated. The linear drive 64 pivots the pressure lever 62 until the pressure roller 60 comes into contact with the elevator 05 and presses it against the lateral surface of the transport cylinder 03. Transport cylinder 03 is then rotated further in a counterclockwise direction by a motor, and in the process the packing 05 is pressed onto the outer surface of transport cylinder 03 in the area of influence of pressure roller 60 until the rear edge of packing 05 reaches the clamping gap formed between clamping jaw 47 and stop 48. When the rear edge of the packing 05 is inserted into the nip, the tensioning shaft 50 is rotated and the nip is thus closed. The pressure roller 60 is then pivoted away. If the elevator 05 is to be removed from the transport cylinder 03 again, the pressure roller 60 remains pivoted away from the transport cylinder 03. Either the front edge or the rear edge of the dressing 05 is released from the transport cylinder 03 and the transport cylinder 03 is then rotated, so that the dressing 05 is conveyed in the direction of the store 72 again. Finally, the edge of the elevator 05 that was still fixed up to that point is released.

The arrangement of a dressing 05 on the stripping cylinder 04 is comparable to the arrangement of a dressing 05 on the transport cylinder 03, so that reference is preferably made to this unless differences are expressly described. To arrange a dressing 05 on the stripping cylinder 04, the stripping cylinder 04 is first rotated into a receiving position provided for receiving the dressing 05. The turning of the stripping cylinder 04 can be done with the help of an individual drive assigned to it or via a gear train that rotates the Stripping cylinder 04 connects to other cylinders in terms of drive technology and into which a main drive drives. The stripping cylinder 04 is preferably driven by an individual drive, whereas the transport cylinder 03 is driven via a gear train which drives the transport cylinder 03 to other cylinders and into which a main drive drives.

In the receiving position, the means for fixing the rear edge of the interchangeable dressing 05 are at least approximately opposite the store 73. The lower edge of the elevator 05 to be fed (which corresponds to the rear edge when it is fixed on the stripping cylinder 04) stands on a storage device 73 comprising holding pins. According to a preferred embodiment, the holding pins are designed as positioning means in the form of positioning pins, which are provided with positioning recesses in the elevator 05 correspond. If positioning pins are formed, the positioning recesses in the packing 05 are opposite the positioning pins and the packing 05 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the dressing 05, the lower edge of the dressing 05 is released from the retaining pins by retracting the retaining pins or by manually lifting the trailing edge off the retaining pins. The pivotably mounted guard 71, which preferably carries a guide roller 67 at the end, is pivoted manually or by motor, resulting in an access opening through which the elevator 05 can be fed to the means for fixing the elevator 05.

As soon as the rear edge of elevator 05 has passed the access opening provided by guard 71 and guide roller 67, guard 71 is pivoted back to its initial position manually or by a motor, so that guide roller 67 contacts elevator 05 and thus elevator 05 on its way is guided to the nip formed between the jaw 22 and the cuff 24. The elevator 05 is preferably fed in by the force of gravity or, alternatively, driven by a motor or manually. When the trailing edge of elevator 05 den Once the clamping gap has been reached, the pneumatic muscle 25 is relaxed and the rear edge of the elevator 05 is thus fixed between the clamping jaw 22 and the impact 24. The stripping cylinder 04 is then rotated clockwise by a motor. When the rear edge of the dressing 05 has moved under the pressure roller 61 as a result of the rotation of the stripping cylinder 04, the linear drive 65 is actuated. The linear drive 65 pivots the pressure lever 63 until the pressure roller 61 comes into contact with the elevator 05 and presses it against the lateral surface of the stripping cylinder 04. The stripping cylinder 04 is then rotated further in a clockwise direction by a motor, and in the process the packing 05 is pressed onto the outer surface of the stripping cylinder 04 in the area of influence of the pressure roller 61 until the front edge of the packing 05 reaches the clamping gap formed between the clamping jaw 47 and the impact 48. When the front edge of the dressing 05 is inserted into the nip, the tensioning shaft 50 is rotated and the nip is thus closed. The pressure roller 61 is then pivoted away. If the elevator 05 is to be removed from the stripping cylinder 04 again, the pressure roller 61 remains pivoted away from the stripping cylinder 04. Either the front edge or the rear edge of the elevator 05 is released by the stripping cylinder 04 and the stripping cylinder 04 then rotates so that the elevator 05 is conveyed back in the direction of the store 73 . Finally, the edge of the elevator 05 that was still fixed up to that point is released.

Another preferred embodiment is in particular in figure 50 shown and will be further described below. The embodiment comprises a conveyor system with chains 106 circulating in pairs, which circulate over front and rear sprockets 107, 108, which are also arranged in pairs. The conveyor system is preferably part of the delivery 99 of a sheet-processing machine, in particular a sheet-fed printing machine, and is preferably arranged downstream of a sheet-guiding cylinder 41 of the sheet-processing machine. Between the pairs of chains 106 is at least one gripper system 17 z. B arranged in the form of a gripper bridge 17. Preferably between the chains 106 are a plurality of Gripper systems or gripper bridges 17 are arranged which, viewed in the transport direction 74, have a constant distance from one another, which is preferably slightly larger than the maximum format of sheet-shaped substrate that can be processed with the sheet-processing machine, in particular sheet-fed printing press. The gripper systems or gripper bridges 17 also extend transversely to the transport direction 74 over the maximum sheet format that can be processed. The gripper systems or gripper bridges 17 preferably comprise gripper fingers arranged next to one another on a gripper shaft, each of the gripper fingers forming a clamping gap with an associated gripper pad, in which the front edge of a sheet-shaped substrate can be fixed. Each gripper shaft is preferably assigned a roller lever, which interacts with a cam that is fixedly or movably mounted on the frame of the conveyor system, such that the gripper shaft rotates and the clamping gap is opened when the roller lever interacts with the curve.

The conveyor system is designed in such a way that the at least one gripper system or gripper bar 17 takes substrate 01 from a sheet-guiding cylinder 41 and conveys it along a conveying path to a delivery pile, above which the respective substrate 01 is released for placement on a delivery pile. The conveying path corresponds to the path covered by the leading edge of a respective substrate sheet 01 fixed by a gripper bridge on its way from a sheet-guiding cylinder 41 to the point at which the leading edge is released again by the gripper system or the gripper bridge 17. A separating device 02 is arranged in the area of the conveying path, with which the substrate 01 can be separated into at least one waste part 09 and at least one blank 10. Separating device 02 comprises a transport cylinder 03 arranged below the conveying path and a stripping cylinder 04 assigned to it and arranged above the transport path.

The structure of the stripping cylinder 04 is 10 and the up 10 related parts of the description can be removed.

The structure of the transport cylinder 03 in the device according to figure 50 is in the Figures 2 to 8 shown in detail and the associated parts of the description, with the difference that the transport cylinder 03 according to figure 50 preferably not the one in the Figures 2 to 8 shown gripper system 17 has. In the embodiment according to figure 50 its function is taken over by the gripper bridge 17.

The transport cylinder 03 has first openings 12 and/or second openings 13 . According to a preferred embodiment, first air supply means 14 are provided for supplying the first openings 12 with air. According to a further embodiment, first air supply means 14 for supplying the first openings 12 and second air supply means 15 for supplying the second openings 13 are provided. The first air supply means 14 supplies the first openings 12 independently of the supply of the second openings 13 by the second air supply means 15.

More preferably, the first and/or the second air supply means 14, 15 can be switched between a suction air supply and a blown air supply.

According to another preferred embodiment, the first and/or the second air supply means 14, 15 are designed to supply air depending on the angular position of the openings 12, 13 supplied in each case. The stripping cylinder 04 can have third openings 32 which can be supplied with air by third air supply means. If the in figure 50 If the illustrated embodiment of the device for treating substrates 01 is associated with or downstream of a sheet-fed printing press or part of the same, the sheet-guiding cylinder is a printing cylinder 41 of a sheet-fed printing press or a cylinder that interacts with a printing cylinder 41 of a sheet-fed printing press. Alternatively, the sheet-guiding cylinder can also be one of two interacting processing cylinders 96, 97, which carry a tool 116 from the group of cutting tools, stamping tools, creasing tools, perforating tools or grooving tools and form a cylinder gap into which the substrate 01 can be inserted for the purpose of processing it.

According to another embodiment, a revolving conveyor belt 29 aligned in the direction of transport 74 is assigned to the transport cylinder 03 . Instead of a conveyor belt 29, several conveyor belts 29 can be provided. A peeling device 31 is preferably arranged between the transport cylinder 03 and the transport belt 29 .

An adjusting device is also preferably provided, with which the distance between the transport cylinder 03 and the stripping cylinder 04 can be adjusted by moving the transport cylinder 03 or by moving the stripping cylinder 04 or by moving the transport cylinder 03 and the stripping cylinder 04. The adjustment device can be designed to implement a first adjustment range of 0 to 5 mm and/or a second adjustment range of 5 to 10 mm and/or a third adjustment range of 50 to 100 mm.

The adjusting device is preferably capable of fine-tuning the relative positions of the interacting cylinders 03, 04 in relation to one another, as well as moving the transport cylinder 03 and the stripping cylinder 04 in and out relative to one another for the purpose of starting up or shutting down the separating device 02. The adjusting device is preferably designed to adjust transport cylinder 03 and stripping cylinder 04 during sheet travel. As a result of this measure, the delivery 99 can be switched over from a separating operation to a full-sheet delivery, also known as a normal delivery. The stripping cylinder 04 preferably has a recess the size of which corresponds at least to the extent of a gripper bridge 17. For driving the stripping cylinder 04 and the transport cylinder 03, one or more drive means are provided which enable a synchronized movement of the two cylinders 03, 04 in relation to one another. At least one drive means for driving the stripping cylinder 04 is configured to be synchronized with the movement of the at least one gripper system 17. This drive means implements such a rotational movement of the stripping cylinder 04 that the at least one gripper system 17, in particular the gripper bar 17, moves within the recess formed in the stripping cylinder 04 when passing the stripping cylinder 04.

At least one of the processing cylinders 96, 97, preferably the lower processing cylinder 96, has a sheet holding system for fixing the leading edges of sheet substrate 01 in place. The sheet holding system of the processing cylinder 96 can be designed as a clamping gripper system or as a suction gripper system. Its function is comparable in particular to the gripper system (clamping gripper system or suction gripper system) of the transport cylinder 03 and can be designed like this.

Each of the processing cylinders 96, 97 has means for fixing an exchangeable dressing 05, which can be designed in particular as a tool 116 or counter-tool.

The frame includes lateral frame walls 109, 110 in which the bearing points 111, 112 are formed. The bearing points 111, 112 are preferably designed as multi-ring bearings, in particular three-ring bearings 113.

The adjusting device 113 enables the cylinder gap between the processing cylinders 96, 97 to be adjusted, e.g. g. to adapt to the thickness of the substrate 01 to be processed. The adjustment device 113 is designed in particular in such a way that the distance between the processing cylinders 96, 97 in the area of the frame wall 109 close to the drive can be adjusted independently of the distance between the processing cylinders 96, 97 in the area of the frame wall 110 remote from the drive is. In other words, the adjusting device 113 can be used to produce or compensate for an inclined position of the processing cylinders 96, 97 in relation to one another.

The processing cylinders 96, 97 are driven on one side, ie a drive torque is only introduced at one end of the respective processing cylinder 96, 97. A common drive with a gear train comprising drive gears 115 or several individual drives can be used for driving be provided. If drive gears 115 are provided, one drive gear 115 is preferably arranged on a leg of the respective processing cylinder 96, 97, preferably outside the frame or in a cavity of the frame.

The drive gears 115 of the two processing cylinders 96, 97 preferably mesh with one another and are preferably connected to a drive motor, which can be designed as a central drive, via further gear elements (not shown), in particular gears. In Figure 51 the upper of the two drive gears 115 is represented by a perspectively distorted circle. Regarding their position in relation to the drive, the z. B. can be embodied by the drive gears 115, a distinction can be made between a frame wall 109 close to the drive and a frame wall 110 remote from the drive. The device for treating substrates can include a temperature control device 114 or a plurality of temperature control devices 114 . According to one embodiment, the temperature control device 114 can be designed for the sole purpose of temperature control of the frame wall 109 close to the drive, ie without temperature control of the frame wall 110 remote from the drive. In this case, the other frame wall 110 has no temperature control device 114 . According to a further embodiment, the temperature control device 114 can be designed to control the temperature of the frame wall 109 close to the drive and to control the temperature of the frame wall 110 remote from the drive. The one or more temperature control devices 114 are designed in particular for temperature control of the respective frame wall 109 near the drive and/or the frame wall 110 remote from the drive between the bearing points 111, 112 of the processing cylinders 96, 97.

The one or each temperature control device 114 preferably comprises one or more cooling devices and/or one or more heating devices. The one or more cooling devices and/or the one or more heating devices are designed to control the temperature of the frame wall 109 close to the drive independently of the temperature control of the frame wall 110 remote from the drive and are preferred, but not mandatory exclusively, between the bearing points 111, 112 of the processing cylinders 96, 97 are arranged.

More preferably, the at least one temperature control device 114 comprises one or two control loops, with which the temperature of the frame wall 109 close to the drive can be regulated independently of the temperature of the frame wall 110 remote from the drive. The control circuits are designed in a manner known per se and each include a temperature sensor, a controller and a controlled system. The respective temperature sensor is assigned to the respective frame wall 109, 110 in such a way that it detects the temperature of the respective frame wall 109, 110 in the area between the bearing points 111, 112. The temperature forms the controlled variable of the respective control circuit.

A setpoint value for temperature control of the frame wall 109 near the drive to a temperature greater than the temperature of the frame wall 110 remote from the drive is preferably input to the temperature control device 114 . The setpoint forms the reference variable of the respective control circuit. The temperature control device 114 can also be input with a further setpoint value for temperature control of the frame wall 110 remote from the drive to a temperature lower than the temperature of the frame wall 109 near the drive, which can form the reference variable of a further control loop.

The desired value and the further desired value represent the temperature or the state that occurs when the processing cylinders 96, 97 are permanently driven.

A preferred method for operating a device for treating substrates 01, in particular one as described above, is presented below.

The preferred method is based on the knowledge that non-uniform deformation of the device for treating substrates 01 as a result of frictional heat does not necessarily have to be avoided.

Targeted non-uniform heating can produce a state of deformation of the device for treating substrates 01 that corresponds to the state of deformation that would result from continuous operation of the device for treating substrates 01 as a result of non-uniform application of heat, or that is at least approximate to this state of deformation.

According to the preferred method, one of the frame walls 109 or both frame walls 109, 110 are tempered, preferably before start-up or after a longer downtime. The tempering takes place in such a way that the frame wall 109 close to the drive is heated to a temperature above the temperature of the frame wall 110 remote from the drive. Then the distance between the processing cylinders 96, 97 is adjusted. This is preferably done in such a way that the distance has the same values everywhere, or the processing cylinders 96, 97 are aligned parallel to one another. The substrate 01 can then be introduced and processed between the processing cylinders 96, 97. During the tempering of the frame wall 109 near the drive, the frame wall 110 remote from the drive is preferably tempered to a temperature below the temperature of the frame wall 109 near the drive. The temperature of the frame wall 110 remote from the drive is preferably above the ambient temperature. In particular, to support the tempering or preheating can also during the tempering Processing cylinders 96, 97 are driven. More preferably, the frame wall 109 near the drive is tempered to a setpoint for tempering the frame wall 109 near the drive and the frame wall 110 remote from the drive is tempered to a further setpoint different from the setpoint for tempering the frame wall 109 near the drive, the setpoint for tempering the frame wall 109 near the drive and the further Target value represents the temperatures that occur when the processing cylinders 96, 97 are permanently driven in the respective frame wall 109, 110, in particular at an ambient temperature between 17 and 23 degrees Celsius, e.g. B. due to the frictional heat of the drive and / or the bearing points 111, 112 and / or other influences. In the ideal case, the desired value and the further desired value are selected in such a way that the temperatures set for the two frame walls 109, 110 remain constant in continuous operation without the need for temperature control by the temperature control device 114 in this state. This condition is reached when the amount of heat supplied by friction is equal to the amount of heat dissipated to the environment as a result of the temperature gradient of the frame walls 109, 110 to the environment.

The device for treating substrates 01, comprising a processing unit 46, can have a device as in Figure 54 processing cylinders 96, 97 shown.

The roughness of the surface of the counter-punching plate or the lateral surface of the other processing cylinder 96, 97 is specifically adjusted in such a way that during a punching process, small material bridges remain between the areas of the sheet-like substrate 01 separated by the punching process, which correspond to the surface structure of the counter-punching plate or the lateral surface of the other Processing cylinder 96, 97 form stochastically distributed small breakpoints or act in the manner of breakpoints.

The size of the breakpoints can be defined by selecting the roughness. If the ceramic layer is applied to the stamping counter plates with a ceramic coating system, the size of the material bridges or the breakpoints of the breakpoint group can be determined by selecting the grain size of the ceramic material. This makes it easy to create and use counter-surfaces for punching different material groups. For example, when paper or cardboard is used as the substrate, the mating surface will have a different, in particular higher, roughness than when processing in-mould label material. In comparison with the roughness of the surface of the counter-punching plate, the roughness of punching contours formed on the punching tools is preferably smaller. The roughness of the punching contours formed on the punching tools is preferably in the range of Rz0.1 to Rz10. Like the counter-punching plate, the punching tools can consist of a ceramic material or a ceramic-coated material. In this case, too, their punching contours have a lower roughness than the roughness of the surface of the counter-punching plate. The punching tools can also consist of tool steel or hard metal or another suitable material.

The plate with the permanently assigned punching tools can also have creasing tools in addition to the punching tools.

The processing cylinder 96, 97, the lateral surface of which is assigned to the counter-punching plate, preferably carries a sheet holding system for fixing the front edges of the sheet-like substrate 01.

The device described for treating substrates 01 can be part of a sheet-processing machine, in particular a rotary printing press or an offset rotary printing press.

The processing cylinder 96, which is preferably embodied as a punching impression cylinder 96, preferably has at least one, more preferably at least two, cylinder channels 133. The at least one and/or each cylinder channel 133 preferably has a front edge 134 or leading edge 134 and a rear edge or trailing edge 135. In particular, the leading edge 134 forms a channel start and is arranged further forward in the direction of rotation for the at least one punching impression cylinder 96 . In particular, the trailing edge 135 forms a cylinder channel end and is preferably further to the rear along the intended direction of rotation and/or the rearmost edge of a cylinder channel 133. In one embodiment, the second processing cylinder 97, which is preferably embodied as a punching cylinder 97, also has at least one cylinder channel 133 with the same designation of the edges . More preferred is the at least one punching cylinder 97 is designed as a magnetic cylinder without a cylinder channel 133. An elevator 05 then preferably holds magnetically on the punching cylinder 97. Such a cylinder channel 133 ensures that the surface of a cylinder barrel is reduced. In particular, such a cylinder channel 133 can be seen as a recess in a cylinder barrel. The at least one sheet holding system embodied as a gripper system is preferably arranged in the at least one cylinder channel 133. Such a counter-pressure cylinder 96 preferably has a circumference that is at least twice the length of a substrate sheet 01. In particular, the at least one counter-pressure cylinder 96 therefore preferably has a second cylinder channel 133. The at least one anvil cylinder 96 has at least one non-contact section with at least one cylinder channel 133. The non-contact portion is disposed so as not to make contact with the punch cylinder 97 during operation.

At least one stop element 136 arranged directly on the trailing edge 135 is arranged in order to shift and/or reduce cylinder start-up vibrations, in particular on the substrate to be processed. Such a contact element 136 is arranged, for example, to enlarge the surface of the cylinder barrel of the at least one counter-punch cylinder 96 . In particular, the at least one stop element 136 is arranged on the trailing edge 135 in the direction of rotation and/or in the circumferential direction, enlarging the surface of the cylinder barrel of the anvil cylinder 96. The at least one contact element 136 is arranged so that it widens the surface of the cylinder barrel of the at least one counter-punch cylinder 96 in the intended direction of rotation. In particular, the surface is expanded over the trailing edge 135 of the respective cylinder channel 133 . For this purpose, the at least one contact element 136 preferably has at least one contact surface 142, which restores the surface of the cylinder barrel of the at least one counter-punch cylinder 96 reduced by the recess of the at least one cylinder channel 133 in some areas. It is important that the surface of the cylinder barrel is expanded, particularly in the direction of rotation away from the trailing edge. At least one Contact element 136, in particular contact surface 142 directed furthest outward, preferably has the same outer diameter as counter-punch cylinder 96. The at least one stop element 136 continues the cylinder surface. For example, such a stop element 136 protrudes at least 5%, more preferably 10%, into the recess of the at least one cylinder channel 133. The surface and/or the contact surface 142 that increases the surface of the cylinder barrel is preferably curved in accordance with the surface of the cylinder barrel and/or has the same curvature as the cylinder barrel. In particular, this ensures a constant increase in the surface area of the cylinder barrel. The at least one anvil cylinder 96 has at least one approach section. The at least one contact surface 142 of the at least one contact element 136 is arranged in the contact section. The curvature of the contact surface 142 preferably corresponds to a curvature of the lateral surface of the counter-punching cylinder 96. The curvature of the contact surface 142 preferably deviates from the curvature of the lateral surface by less than 10%.

The at least one stop element 136 is arranged, for example, centrally in the transverse direction and/or the axial direction, in particular in the inner 30% of the width, the transverse direction and/or the axial direction of the at least one cylinder channel 133. The at least one stop element 136 is preferably arranged at a channel end and/or the trailing edge 135 by means of fastening means 141. The at least one sheet holding system designed as a gripper system preferably has a plurality of grippers in the transverse direction. In particular, the at least one stop element 136 is preferably arranged between one of the grippers and/or between the grippers in the transverse direction. The at least one contact element 136 is preferably arranged in the circumferential direction between the trailing edge 135 and the gripper system. In a further preferred embodiment, several stop elements 136 are arranged, preferably in the transverse direction in the cylinder channel 133 . The plurality of contact elements 136 are preferably each arranged between grippers and preferably arranged on the trailing edge 135 . At the points where contact elements 136 are arranged, the grippers of the gripper system must give way in the case of adjacent sheet guiding cylinders 42. In particular, a number of contact elements 136 is thus limited. In particular, it may be the case that, depending on the embodiment, the grippers have to be removed accordingly even if the sheet guiding cylinders 42 are arranged beforehand. This means that the grippers of the adjacent sheet guiding cylinders 42 are removed in the area in which the contact elements engage. To do this, individual grippers can be removed from the gripper system. It must also be ensured that the substrate 01 is adequately held.

In contrast, at least one elevator 05, in particular tool 116, is preferably arranged on the at least one punching cylinder 97. In particular, the at least one dressing 05 is designed to match the at least one contact element 136, in particular in terms of shape. The at least one dressing 05 preferably has at least one tab 137 embodied as element 137. A packing 05, which is arranged on the at least one punching cylinder 97, has at least one element 137 that comes into contact with the at least one contact element 136. The at least one tab 137 preferably protrudes from the dressing 05 in the direction of rotation. In particular, the at least one tab 137 has at least one contact surface 138. In particular, the contact surface 138 is the surface that comes into contact with the surface of the at least one and/or the plurality of stop elements 137 . At least the at least one contact surface 138 is therefore preferably outside of the region of elevator 05 and/or tool 116 that produces the die-cut image. At least the at least one contact surface 138 is preferably further forward in the intended direction of rotation of the at least one die-cutting cylinder 97 and in particular in front of the remaining surface of the elevator 05 and/or tool 116. Thus, after a cylinder channel 133 and/or the cylinder channels 133 have passed through, the at least one contact surface 138 of the at least one packing 138 and the surface of the at least one contact element 136 come into contact first. The contact surface 138 of the at least one tab 137 and a surface of the Cylinder barrel is arranged in the direction of rotation to take place before contact of the remaining surface of the dressing 05 and the remaining surface of the cylinder barrel. In a preferred embodiment, the at least one punching counter-pressure cylinder 96 has as many tabs 137 as associated contact elements 136. In particular, four contact elements 136 and associated four tabs 137 are preferably arranged. The at least one lift also has register holes 140 . At least the outermost tabs 137 preferably have such register holes 140. One of register holes 140 is preferably designed as a round hole and one as a transverse hole. In particular, precise application of a dressing 05 through register holes 140 is ensured. In a first embodiment, the inner tabs 137 also have register holes 140 of this type. In a further preferred form, only the outermost tabs 137 each have a register hole 140 .

The at least one contact surface 138 preferably has at least one punched pattern 139 and/or shaped elements 139. In particular, punched pattern 139 means a pattern which is scratched into and/or applied to contact surface 138 . In particular, the best possible reduction in cylinder start-up vibrations is possible. For example, the contact surface 138 can have parallel lines in a vertical and/or horizontal arrangement. Such form elements 139 can be included in a file of a punching layout and thus easily integrated into the manufacturing process of the punching plates. During operation, the contact surface 142 is arranged on the at least one contact section of the at least one anvil cylinder 96 so that it comes into contact with the contact surface 138 of the at least one tab 137.

The at least one anvil cylinder 96 has at least one punching section with at least one support surface 143 provided for substrate 01. The seating surface 143 is the surface provided for a substrate during stamping. In the punching section, a punching surface 144 of the elevator 05 is arranged so that it comes into contact with the depositing surface 143 for a substrate 01. The start-up section of the anvil cylinder 96 is the Stamping section, preferably arranged directly upstream. The at least one approach section is arranged downstream of the at least one contactless section, preferably directly.

The cylinder start-up vibration, in particular the maximum of a cylinder start-up vibration, is shifted at least partially before arrival of a substrate 01 by means of the at least one stop element 136 and/or the cylinder start-up vibration on the substrate 01 is reduced. During operation and/or during rotation, the at least one punching cylinder 96 and at least one counter-punching cylinder 97 are at least temporarily out of contact through the at least one cylinder channel 133, in particular when passing through the at least one non-contact section. When the at least one following approach section makes contact again, in particular when there is cylinder contact between the at least one punching cylinder 96 and the at least one counter-punching cylinder 97, vibrations occur, in particular cylinder approach vibrations. In particular, the at least one contact surface 142 comes into contact with the at least one contact surface 138 during operation. In particular, cylinder start-up vibrations mean vibrations that have a maximum and then decay. The maximum is preferably very close to the contact surface and then decays along the circumference. At least a first cylinder contact of the at least one punching cylinder 96 and the at least one counter-punching cylinder 97 after passing through at least one cylinder channel 133 by means of at least one stop element 136 takes place earlier, in particular before the punching surface comes into contact with the substrate 01. In particular, the at least one tab 137 and the at least one contact element come into contact before substrate 01 arrives in the cylinder gap. The at least one first cylinder contact of the at least one punching cylinder 96 and the at least one counter-punching cylinder 97 takes place earlier, after they have passed through at least one cylinder channel 133, before a surface of a dressing 05 designed for punching comes into contact with a substrate 01 by means of the at least one stop element 136. In operation, at least one part and/or one Tab 137 of at least one dressing 05 in front of the remaining surface of a dressing 05 in contact with at least one run-up element 136. In operation, after the at least one run-up section has been run through, the at least one punching section follows. In the at least one stamping section, a substrate 01 is stamped on the at least one storage surface 143 using the at least one stamping surface 144 of elevator 05. In at least one punching section, a cylinder start-up vibration has at least partially subsided. As a result of the contact between the at least one tab 137 and the at least one stop element 136, a cylinder start-up vibration is shifted at least partially before a substrate 01 arrives in the cylinder gap. In particular, the cylinder start-up vibrations that affect the substrate are significantly reduced.

After the at least one punching section, the at least one substrate 01 is guided on to at least one sheet guiding cylinder 42.
