The device for treating substrates 1 with a separating device 2, with which processed substrate 1 can be separated into at least one waste part 9 and at least one blank 10, can be designed as an independent machine and in this case has a feed system for substrate 1 that is not described in detail .

According to a further embodiment, the separating device 2 is part of a substrate-processing machine, in particular a sheet-processing machine, and is operated inline with the aggregates of the sheet-processing machine. In particular, a sheet-fed printing press is provided as the sheet-processing machine, such as is used, for example, in 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 machine includes a feed system for substrates 1, also referred to as feeder 7. Substrates 1 are in particular sheet-shaped workpieces made of paper, cardboard, cardboard, corrugated cardboard, plastic or the like, which are preferably printable or printed. The substrates 1 are present as a stack in the feeder 7 of the sheet-fed printing press and are separated by it and fed via an acceleration system 8 to the aggregates of the sheet-fed printing press downstream of the feeder 7 . The sheet-fed printing press comprises at least one, preferably several, printing units 6. The printing units 6 each comprise, in particular, a printing cylinder 41 and a sheet-guiding cylinder 42, preferably embodied as a transfer drum 42. A rubber-blanket cylinder 43 carrying a rubber blanket is assigned to the printing cylinder 41, 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 6, substrate sheet 1 is guided in a manner known per se by the sheet holding systems provided on impression cylinder 41 and sheet-guiding cylinder 42, printed in the printing gap formed between impression cylinder 41 and blanket cylinder 43 and then to the subsequent unit of the sheet-fed printing press, e.g. in the form of the next printing unit 6, passed. One or more processing units 46 can be formed after the printing unit(s) 6 or between the printing units 6. The processing units 46 preferably comprise two processing cylinders, one of which, preferably the lower one, has a sheet holding system and the other, preferably the upper one, has a tool carrier. The processing cylinders are associated with one another to form a cylinder gap. At least one of the processing cylinders carries a tool. In the simplest case, a pair of processing cylinders is created by the pressure cylinder 41 and blanket cylinder 43 of a printing unit 6 is formed. In this case, a printing unit 6 serves as a processing unit 46. In this case, the clamping device for the rubber blanket is used to fasten the tool on the rubber blanket cylinder 43.

The processing cylinders can be designed in many different ways. According to one embodiment, which is particularly suitable for punching and perforating applications, the upper processing cylinder is designed as a solid magnetic cylinder or carrier cylinder with magnet segments for receiving magnetic sheets or magnetic sheets and the lower processing cylinder as a surface-hardened cylinder or with a hardened sheet metal attached.

According to another embodiment, which is particularly suitable for embossing or creasing or grooving applications, the upper processing cylinder is a solid 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 elevator carriers that act mechanically, in particular with a positive or non-positive fit. 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 1, which can be embodied as a sheet-processing machine or can be a component thereof, 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 1 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 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 .
The counter-cylinder 98 is assigned to the processing cylinder 97 in such a way that when the processing cylinder 97 deflects, as occurs when processing substrate sheet 1 in the gap between the two processing cylinders 96, 97, the force of the resulting bending force of the second processing cylinder 97 causes the 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 first and of the second processing cylinder 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 bearer ring is approx. 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 makes it possible to arrange an elevator on the counter cylinder 98 to ensure that this is in surface contact, in particular rolling contact, with the processing cylinder 97 or with the tool arranged on its surface, even when the tool is arranged on the second processing cylinder 97 and the thickness of the tool can vary . 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 exchange of tool parts, the device for treating substrates 1 comprises a processing unit 46 with two interacting processing cylinders 96, 97, between which the substrate 1 can be inserted. The substrate 1 is processed as it passes through tool parts from the group of cutting tools, stamping 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 exchange of tool parts, the device for treating substrates 1 comprises a separating device with a transport cylinder 3 and a stripping cylinder 4, between which the substrate 1 can be inserted. The substrate 1 is separated into at least one waste part 9 and at least one blank 10 by at least one elevator 5 as it passes through the cylinder gap between the transport cylinder 3 and the stripping cylinder 4 . The transport cylinder 3 and/or the stripping cylinder 4 are designed as magnetic cylinders. A peeling device 103 for peeling off the at least one elevator 5 is assigned to the transport cylinder 3 and/or the stripping cylinder 4 . See in particular 47 and 48 . The stripping device 103 can be set on and/or off the cylinder to which it is assigned and which is designed to carry a lift 5 , in particular the processing cylinder 96 , 97 or the transport cylinder 3 or the stripping cylinder 4 . The peeling device 103 has a peeling edge 104 . When the peeling device 103 is placed on the respective cylinder, the peeling edge 104 extends preferably 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 3 or stripping cylinder 4. 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 mechanism 46 or a separating mechanism 2.2, which protects the operator from injuries caused by the rotating cylinder or avoids or reduces noise or dust emissions. 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 5 in place. The holding element can act pneumatically or magnetically or be designed in another suitable manner, e.g. in the form of a step or pawl.

In order to ensure that the peeling device 103 grips an edge of the tool part or the at least one dressing 5, the tool part or the at least one dressing 5 can be lifted off manually. According to an advantageous alternative, an ejector is configured for this purpose, which is assigned to the processing cylinder 96, 97 and/or the transport cylinder 3 and/or the stripping cylinder 4 and which is used to at least partially lift tool parts or the at least one elevator 5 from the surface of the Processing cylinder 96, 97 or the transport cylinder 3 or the stripping cylinder 4 is formed.

Preferably, a drive acting on the processing cylinder 96, 97 and/or the transport cylinder 3 and/or the stripping cylinder 4 is provided, with which a drive controller interacts. The drive control causes the processing cylinder 96, 97 and/or the transport cylinder 3 and/or the stripping cylinder 4 to be automatically positioned in a position in which one end of a tool part or of the at least one elevator 5 is opposite the peeling device 103 and/or is in the Effective range of the peeling device 103, in particular the peeling edge 104 is located. After positioning, the drive control cause the processing cylinder 96, 97 and/or the transport cylinder 3 and/or the stripping cylinder 4 to rotate in such a way that the other end of the tool part or of the at least one elevator 5 is opposite the peeling device 103 and/or is in the effective range of the peeling device 103. During the twisting, the peeling device 103 peels the tool part or the at least one dressing 5 from the respective cylinder surface. Between the positioning and turning of the processing cylinder 96, 97 and/or the transport cylinder 3 and/or the stripping cylinder 4, the ejector is used to at least partially lift the respective tool part or the at least one elevator 5 from the surface of the processing cylinder 96, 97 or the transport cylinder 3 or the stripping cylinder 4 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 or tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools or grooving tools.

For all of the described embodiments with a film application unit 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, for example for the production of envelopes, the cutting or punching lines or material tears as a result of cutting or punching in the substrate 1 would appear on the inside of the envelopes, where they would be less disruptive than on the outside.

In the following, a preferred method for treating sheet-like substrates 1 is described, which with one of the versions according to the 33 until 46 can be carried out.

The procedure is as follows.
In a punching process step, window-shaped areas are punched in the substrates 1, with material connections being retained. In a separating process step, which preferably immediately follows the punching process step, the window-shaped areas are broken out of the substrates 1, with the material connections being severed so that window-shaped recesses are formed in the substrates 1. In a process step of coating, which preferably immediately follows the process step of separating, the substrates 1 are coated with adhesive in the adjoining area of 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 1, in each of which at least one window-shaped area is arranged, further material connections between the blanks 10 and between blanks 10 and waste parts 9 being retained. In the case of windowed envelope production, such a blank 10 would represent an unfolded envelope. After window application, the substrates 1 are either placed directly on a stack or on a conveyor belt 29, 30, alternatively, before being placed, the further material connections between the panel 10 or between the panel 10 and the waste parts 9, e.g. the outer frame, can be separated in a further separating process , to be severed. It is also possible to print the substrates 1 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.

Another embodiment relates to a method for treating sheet-like substrates 1.

The procedure is as follows.

A respective substrate sheet 1 is separated from a stack formed from substrate sheet 1 by a feeder 7, then embossed and/or dried in a first processing unit 46, then grooved or punched and/or punched 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 1 is preferably printed in one or more printing units 6 and/or varnished in one or more coating units between the separation in the feeder 7 and the treatment 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 1 or blanks 10 are preferably deposited in a delivery 99 or on a conveyor belt 29, 30 in a stack or as a sequence, shingled or not.

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 the processing of materials by pressure with appropriate tools genes understood, the material being shaped and / or deformed in relief.

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

Perforating is the processing of materials by pressure with appropriate tools, with a large number of mostly linearly arranged holes being made in 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 in any order with other plants to implement changed production processes. 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 2.2, 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, transfers the substrate 1 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 film applicator unit or window applicator unit 85, after going through various processing stages, either substrate sheets 1 (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 downstream 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 1, in particular benefit 10, can be connected to the downstream conveyor belt 18 and 19 is described. The device comprises a circulating conveyor belt 29, 30, which conveys the substrates 1, in particular blanks 10, in at least one path, preferably in an imbricated stream, against at least one stop 77 for depositing the substrates 1 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. For handling, in particular moving, the stack carrier 78, a transport device 79 is provided, with which the stack carrier 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 sheet 1 or panel 1 conveyed by the conveyor belt 29. 30 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. If a gap is to be formed in the imbricated stream, for example because 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 further conveys substrate sheets 1 as a result of its movement, these are accumulated on the cylinder 83 or roller. The roller 83 or roller can be mounted in a stationary or rotatable manner and is preferably braked in the latter case.

The transport device 79 is designed to move the stack carrier 78 into one or more positions in which the stack carrier 78 and the at least one 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 side by side on the conveyor belt 29, 30 transversely to the transport direction 74 of the substrate sheet 1 or the panel 10. More preferably, each group stops 77 have 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 1 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 formed, with which at least one separating element 81 can be positioned on the substrates 1 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 separating elements 81 are preferably sheet-like materials that can be inserted between stacks of blanks to spatially separate them from one another. 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 20 until 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 1 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. In the further course, the stack of substrate sheet 1 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 1 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 1 or panel 10 has reached a sufficient height, the stops 77, if they were shifted with the stack carrier 78, are shifted back vertically to their starting position. The stack carrier 78 is displaced vertically to its starting position and horizontally by a distance which corresponds to the length of the substrate sheets 1 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 1 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 1 or panel 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 1 or blanks 10, once or several times, until a further stack or further stacks are formed with the desired height, which, viewed in the transport direction 74, lie one behind the other and possibly also next to one another ( 25 ).

At this point in the process, the feed device 80 can be used. This detects the uppermost separating element 81 of the separating elements th 81 formed stack 82 and transports it over the stack formed on the stack carrier 78 from substrate sheet 1 or panel 10, where it is released and arrives for deposit on the respective uppermost substrate sheet 1 or panel 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 1 or blanks 10 are formed on the new stack level. For this purpose, the stack carrier 78 is positioned in relation to its vertical position by the transport device 79 in such a way that the new stack level is below the release level of the transport 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 )

When the conveyor belt 29, 30 is circulating, substrate sheets 1 or blanks 10 are then conveyed onto the separating element 81 and are aligned laterally by the stops 77 and preferably also in the transport direction 74. In the further course, the stack of substrate sheet 1 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 1 or blanks 10 without vertical movement. When the stack of substrate sheet 1 or panel 10 has reached a sufficient height, the stops 77, if they were shifted with the stack carrier 78, are shifted back vertically to their starting position. The stack support 78 is displaced vertically to the position it occupied at the beginning of the formation of the first stack on the separating element 81 and horizontally by a distance which corresponds to the length of the substrate sheets 1 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 1 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 1 or copy 10 can be formed on the separating element 81 ( 31 ). If a sufficient number of stacks of substrate sheets 1 or blanks 10 have been formed on the stack carrier 78, the loaded stack carrier 78 is transported away and replaced by a new stack carrier 78 that can receive it.

The sequence of the works of the sheet-fed press results from the technological requirements. One or more processing units 46 are preferably formed after one or more printing units 6 . In the case of several printing units 6, these are usually equipped with different tools 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 6 . Alternatively, one or more processing units 46 can also be interposed between one or more printing units 6 . The sheet-fed printing press preferably also includes one or more varnishing units, which are preferably connected downstream of the printing units 6 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 structure as the sheet-fed printing press described, minus the printing units 6 .

Following the printing units 6 or the processing units 46, the separating device 2 is formed. The separating device comprises a transport cylinder 3. The transport cylinder 3 is double-sized, ie it transports two substrate sheets 1 per revolution. However, the invention is not limited to a double-sized version of the transport cylinder 3. 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 3 there is a sheet holding system for fixing the front edges of the sheet-like substrate 1, in particular a gripper system (in the case of a double-sized system, two sheet holding systems are formed). The gripper system is preferably designed as a suction gripper 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 3 is a multiple of its extent in the circumferential direction. The extent of the suction area of the suction gripper system 17 in the circumferential direction of the transport cylinder 3 is preferably 15 mm. The suction area can be a continuous opening extending across the width of the transport cylinder 3 or a multiplicity of suction openings lying next to one another be educated. The extension of the suction area in the axial direction of the transport cylinder 3 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 feed path of the suction air for the suction openings which are on the outside in relation to the center of the transport cylinder 3. The adjustability of the extension of the suction area has the advantage that suction air consumption is minimized. The transport cylinder 3 also preferably has means (in the case of a double-sized system, two fixing means are formed) for fixing an interchangeable elevator 5 . The means for fixing are preferably designed as clamping grippers. With them, a respective lift 5 can be fixed at the rear edge and at the front edge. The means for fixing the front edge of the dressing 5 are preferably formed by the clamping element front edge 22 (also referred to as the clamping jaw) and the further clamping element 24 (also referred to as the impact) 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 3 . The clamping element 22 is firmly connected to a lever 21 which is mounted on the base body of the transport cylinder 3 such that it can pivot about a pivot point 34 . The lever 21 is braced by an energy accumulator 23, preferably designed as a spring, in such a way 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 3 . The 3 shows the front edge clamping gripper with the front edge of the lift 5 fixed, ie in the closed state. The 4 shows the front edge clamping gripper with the front edge of the elevator 5 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 3 . 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 3 . 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 22 of the clamping element on the other front edge clamping element 24 or the lift 5 . The rear edge of the packing 5 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 .

For tensioning the elevator 5, 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 3 . The carriage 49 preferably carries the tensioning shaft 50 and the toggle lever 51 in addition to the rear edge of the clamping gripper. Then the carriage 49 is 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 5, they preferably carry positioning pins or are preferably associated with 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 3 preferably has first and second openings 12, 13 which, when the elevator 5 is fixed, are at least partially covered by the openings that can be formed in the elevator 5. 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 following context, air is understood to mean all forms of system air, ie in particular blown air or suction air, which are suitable In particular, physical effects such as force are to be exerted 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 by the first and second air supply means 14, 15 and, in particular, together with all the means which 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 3. The first and second openings 12, 13 are preferably arranged alternately in the circumferential direction of the transport cylinder 3 or in the axial direction of the transport cylinder 3. 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 outer surface of the transport cylinder 3 preferably results in a fine-meshed network of elements with which any openings formed in the elevator 5 can be supplied with air. The arrangement of the openings in the lift 5 takes place in accordance with the arrangement of the waste part or waste parts 9 on the one hand and the panel 10 on the other. For example, in the area of those first openings 12 that are formed in the area of the panel, openings can be formed in the lining 5, while all second openings 13, which are formed in the area of the panel 10, have no openings in the lining 5 opposite. The same applies analogously to the area of waste parts 9, in which case the second openings 13 are opposite openings in the lift 5, while the first openings 12 are covered by closed areas of the lift 5. Through these measures, benefit 10 and waste parts 9 can be treated differently or fixed on the lateral surface of the transport cylinder 3 or its elevator 5 .

The details of the air supply to the first and second openings 12, 13 are particularly shown in FIGS 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 3 or assigned to it. Two rotary slides or two rotary inlets are preferably formed on opposite end faces of the transport cylinder 3 . At the in the 5 , 6 and 7 In the example shown, the rotary slide or the at least one rotary inlet comprises a disk 18 which is assigned to one of the end faces of the transport cylinder 3 . A plurality of groove-shaped recesses 19 , 56 , 57 are formed in the disc 18 , which preferably extend in the shape of a segment of a circle, coaxially with the axis of rotation 16 of the transport cylinder 3 . 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 disc 18 facing the transport cylinder 3 . 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 3. 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 in terms of their distance (radius) to the axis of rotation 16 of the transport cylinder 3 with openings 58 formed in the end face of the transport cylinder 3. Each of the openings 58 in the end face of the transport cylinder 3 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 3 or with the suction gripper system 17. Of course, this only applies as long as the respective opening of the respective recess 19, 56 and 57 depends on the angular position of the Transport cylinder 3 opposite. At the in 2 In the embodiment shown, the recesses 57 closest to the axis of rotation 16 of the transport cylinder 3 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 disk 18 is stationary relative to the transport cylinder 3, which rotates about the axis of rotation 16 in the operating state. By extending the recesses 19, 56 and 57 in the circumferential direction of the Transport cylinder 3 areas of suction or blast air are determined, which are formed on the lateral surface of the transport cylinder 3 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 3 is used for fixing and the blowing area for repelling blanks 10 or waste parts 9. 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 suction air supply to blowing air supply when the respective first openings 12 reach a first release point as a result of the transport cylinder 3 rotating about its axis of rotation 16 . More preferably, the second air supply means 15 switch the air supply of the second openings 13 off or from suction air supply to blowing air supply when the respective second openings 13 reach a second release point as a result of the transport cylinder 3 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 3 . The transport cylinder 3 is preferably rotatably mounted in the same frame to which the torque arm 20 is articulated.

To shift the areas of suction or blown air, which are formed on the lateral surface of the transport cylinder 3 in relation to the angle of rotation, adjusting elements 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 8th 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 3 . In this embodiment, too, the recess 57 is supplied with air by a third supply connector 55 . The recess 57 is formed on the side of the disk 18 facing the transport cylinder 3 . 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 3, the recess 57 corresponds to one or more openings 58 formed in the end face of the transport cylinder 3. 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 3 opposite. In other words, the length and position of the angular range in which suction air is applied to the suction pad system 17, i.e. 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 outer surface of the transport cylinder 3 . The suction gripper system 17 is preferably assigned to the means for fixing the elevator 5 in place. In particular, the suction gripper system 17 can be mounted on the means for fixing the elevator 5 . The means for fixing the elevator 5 in place and thus also the suction gripper system 17 are preferably mounted such that they can be moved, in particular pivoted. 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 4 is arranged adjacent to the transport cylinder 3 . Like the transport cylinder 3, the stripping cylinder 4 is rotatably mounted. The stripping cylinder 4 is used to break out waste parts 9 or 10 blanks. The stripping cylinder 4 preferably has third openings 32 . Third air supply means are provided for supplying the third openings 32 with air.

Like the transport cylinder 3, the stripping cylinder 4 can also be double-sized or single-sized. In the case of a double-sized design of the stripping cylinder 4, its circumference or diameter corresponds to the circumference or diameter of a double-sized transport cylinder 3. The stripping cylinder 4 is preferably designed to be single-sized. In terms of its construction, the stripping cylinder 4 preferably resembles the transport cylinder 3 in many features, so that for the description of the structure of the stripping cylinder 4 reference is made to the explanations regarding the structure of the transport cylinder 3 . This applies in particular to all assemblies of the transport cylinder 3 or the stripping cylinder 4 for which structural differences or an absence are not expressly pointed out. The nature of the stripping cylinder 4 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 the transport cylinder 3, the stripping cylinder 4 does not include a sheet holding system for fixing the front edges of the sheet-like substrate 1.

Like the transport cylinder 3 , the stripping cylinder 4 preferably has means for fixing an exchangeable elevator 5 . The means for fixing are preferably designed as clamping grippers. With them, a respective lift 5 can be fixed at the rear edge and at the front edge. The means for fixing the front edge of the dressing 5 are preferably formed by the clamping element front edge 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 4 . 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, for example in the form of compressed air, to the actuating element 25, the gap formed between the clamping element front edge 22 and the further clamping element 24 can be enlarged and Switching off the overpressure on the actuating element 25 are reduced, which corresponds to the jamming of the elevator 5. The 10 shows the clamping gripper of the stripping cylinder 4 front edge with a fixed front edge of the elevator 5, ie in the closed state.

The rear edge of the packing 5 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, ie the front edge clamping gripper or the rear edge clamping gripper, can be displaced in the circumferential direction of the stripping cylinder 4 for tensioning the elevator 5 . 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 slide 49 that can be displaced in the circumferential direction of the stripping cylinder 4 . The carriage 49 preferably carries the tensioning shaft 50 and the toggle lever 51 in addition to the rear edge of the 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 5, they preferably carry positioning pins or are preferably associated with positioning elements. The position ing 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. Thus, as an alternative to the formation of non-positively acting elements, it also proves to be advantageous if the elements for fixing the front edge and/or the elements for fixing the rear edge are formed for the form-fitting fixing of elevators 5 . In this case, in particular, hook-shaped or claw-shaped retaining elements can be formed, which correspond to recesses that are formed in the elevator 5 or engage in retaining rails that are firmly connected to the elevator 5.

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 4, which can be covered by a channel cover.

The stripping cylinder 4 preferably has third openings 32 which, when the dressing 5 is fixed, are at least partially covered by the openings that can be formed in the dressing 5 . 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.e. in particular blown air or suction air, which are suitable in particular for exerting a physical effect such as force and which can be characterized by at least one of the parameters static pressure, dynamic pressure or volume flow. 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 surface area of the stripping cylinder 4 . The third openings 32 are preferably in the form of grooves or holes. The arrangement of third openings 32 in the lateral surface of the stripping cylinder 4 preferably results in a fine-meshed network of elements with which any openings formed in the elevator 5 can be supplied with air. The arrangement of the openings in the lift 5 takes place in accordance with the arrangement of waste part or parts 9 on the one hand or panel 10 on the other hand. For example, in the region of those third openings 32 that are formed in the region of use, openings can be formed in the elevator 5. This proves to be advantageous if the stripping cylinder 4 is to be used to transport the panel 10.

If the use of the stripping cylinder 4 for transporting waste parts 9 is provided, openings in the elevator 5 are preferably formed in the region of those third openings 32 which are formed in the region of waste parts 9 . Through these measures, blanks 10 or waste parts 9 can be treated differently or fixed on the outer surface of the transport cylinder 3 or its elevator 5 . The release of the blanks 10 or waste parts 9 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 3. 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 3 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 4 . A recess X is formed in the disk 18 and preferably extends in the shape of a segment of a circle, coaxially with the axis of rotation of the stripping cylinder 4 . 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 4 . 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 . Each recess corresponds in terms of its distance (radius) to the axis of rotation of the stripping cylinder 4 with openings 58 formed in the end face of the stripping cylinder 4. Each of the openings 58 in the end face of the transport cylinder 3 communicates via additional lines either with a single or part or all third openings 32 in the lateral surface of the stripping cylinder 4. 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 4.

The disc 18 is stationary relative to the stripping cylinder 4, which rotates about its central axis in the operating state. The extent of the recesses in the circumferential direction of the stripping cylinder 4 determines areas of suction or blast air that are formed on the outer surface of the stripping cylinder 4 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 extent of 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 4 is used for fixing and the blowing area for removing blanks 10 or waste parts 9.

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. Preferably, the third air supply means 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 by rotation of the stripping cylinder 4 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 4 . The stripping cylinder 4 is preferably rotatably mounted in the same frame to which the torque support 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 4 in relation to the angle of rotation, actuators for rotating the disc 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 4 in the region of the stripping cylinder 4 in which the disk 18 is associated with it.

The stripping cylinder 4 and the transport cylinder 3 preferably each carry a lift 5 for treating substrates 1, in particular for separating or breaking out processed, i.e. cut or cut through, ridged or perforated substrate 1 into at least one waste part 9 and at least one panel 10. When separating or breaking out, 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 9 and at least one benefit 10 are torn. For this purpose, one of the elevators 5 can be designed as a female mold and the other elevator 5 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 1 and form tools. The die has a base plane and areas that are recessed relative to the base plane or other recesses. Die and patrix are arranged on the transport cylinder 3 or stripping cylinder 4 in such a way that the raised areas of the patrix 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 3 or the stripping cylinder 4 and the patrix on the other cylinder. The other cylinder in this sense is the cylinder cooperating with the cylinder carrying the matrix (transport cylinder 3 or stripping cylinder 4). The matrix is preferably arranged on the transport cylinder 3 and the patrix on the stripping cylinder. The above-described pair of tools male and female preferably differs from male and female tool pairs as they are used for cutting or perforating, e.g. on the processing cylinders upstream of the cutting device 2 . 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, the patrix is included at least on the side facing the matrix provided with an elastic coating or formed from an elastic material.

When separating or breaking out, waste parts 9 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 9 or the blanks 10 are preferably pressed by the male mold into the recessed areas or the further recesses of the female mold. In the case of using a male mold with an elastic surface, the waste parts 9 are pressed into the recessed areas or the further recesses of the female mold, whereby the surface of the male mold expands in these places, 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 3 is not assigned a stripping cylinder 4, with the waste parts 9 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 cutting lines. The separating device 2 is preferably designed in such a way that it acts exclusively on that side of the processed substrate 1 which faces the transport cylinder 3 , while the substrate 1 is being transported on the transport cylinder 3 . In a preferred embodiment, the separating device 2 is formed from raised areas and areas of the surface of the transport cylinder 3 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 3 is assigned an interchangeable dressing 5, with the raised areas of the surface of the transport cylinder 3 being replaced by the dressing 5 and the recessed areas of the surface of the transport cylinder 3 being replaced by the lateral surface of the transport cylinder 3 in the area of openings formed in the dressing 5 are formed. 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 3 . 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 realize the relative movement of the waste parts 9 and blanks 10 relative to one another, the transport cylinder 3 can be assigned a lift 5 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 9 and blanks 10 relative to one another, i.e. in particular pulls the waste parts 9 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 9 are supported on the base plane of the matrix. 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 9 facing transport cylinder 3 . 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 9 facing the transport cylinder 3.

When separating the substrate sheets 1 into waste parts 9 and copies 10, problems arise, particularly in environments with low humidity, which are caused by undesirable electrostatic charges on the waste parts 9 and/or copies 10 and/or the surfaces of the transport cylinder 3 and/or stripping cylinder 4. As a result of the electrostatic charges, waste parts 9 and/or blanks 10 adhere to the surfaces of transport cylinder 3 and/or stripping cylinder 4. In these cases, the effect of gravity is usually not sufficient to remove waste parts 9 and/or blanks 10 from the cylinder surface or .to be removed from the tools 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 2 to be formed which comprises a transport cylinder 3 and a stripping cylinder 4 assigned to it, with the transport cylinder 3 and/or the stripping cylinder 4 being assigned an antistatic device 95 is ( 9 ). The transport cylinder 3 preferably has means for fixing an interchangeable dressing 5, and openings 12, 13 which, when the dressing 5 is fixed, are at least partially covered by openings that can be formed in the dressing 5, with air supply means 14, 15 for supplying the openings 12, 13 with air are provided. The antistatic device 95 preferably comprises at least 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 the transport cylinder 3 and/or stripping cylinder 4 or the tools 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 process the value of the applied voltage as a system parameter 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 4 over its length and/or in the axial direction of the transport cylinder 3 over its length.

Furthermore 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 3 and/or the lateral surface of the stripping cylinder 4.

As an alternative or in addition to the design of the separating device 2 with an antistatic device 95, the tools or tool parts used, such as dies and male dies, and/or the cylinder surfaces of transport cylinder 3 and/or a stripping cylinder 4 assigned to it can also be antistatic, in particular with electrically conductive materials. be formed.

According to another preferred embodiment, with or without a stripping cylinder 4, a circulating conveyor belt 29 is assigned to the transport cylinder 3, as shown in particular in FIG 11 or 12 . is evident. The conveyor belt 29 is preferably arranged above the transport cylinder 3 . The conveyor belt 29 is assigned to partially wrap around the transport cylinder 3, preferably forming a wrap angle. As an alternative to this, the transport belt 29 can also be associated with the transport cylinder 3 , forming a tangent point 36 . More preferably, the tangent point 36 is formed in the 12 o'clock position of the transport cylinder 3 . 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 hanging transport of use and/or waste parts 10, 9.

The conveyor belt 29 has in particular the function of processed substrate sheets 1, waste parts 9 or blanks 10 at the tangent point 36 or in the area of the wrap around the conveyor belt 29 in order to take over the transport cylinder 3 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 further conveyor belt 30, in which functionally processed substrate sheets 1 or blanks 10 and/or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30. More preferably, the further conveyor belt 30 is designed for horizontal transport of blanks and/or waste parts 10, 9.

It goes without saying that instead of the additional conveyor belt 30, another suitable transport system can also be configured that accepts processed substrate sheets 1 or blanks 10 and/or waste parts 9 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 assigned directly to the transport cylinder 3, i.e. forming a transfer area or transfer point between the transport cylinder 3 and the other transport system for processed substrate sheets 1 or panels 10 and/or waste parts 9. 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 . illustrated embodiment two processing cylinders, between which the substrate 1 can be inserted, wherein the substrate 1 undergoes processing when passing through effective tool parts in the cylinder gap from the group of cutting tools, punching tools, grooving tools, perforating tools. 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 1 to the transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, holds the processed substrate sheet, in particular the cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and has indentations at the points at which it acts on the blank 10 Mistake. Perforations are made on the one hand in the area of the panel 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 5, ie closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, ie closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3, the blanks 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, make contact with the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The residual webs that the waste parts 9 connect to the frame or to good parts 10, torn. Preferably at the 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 9, which fixes the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. 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 9 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 3 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 3 in the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away hanging therefrom. The transfer of the blanks 10 from the transport cylinder 3 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 9 reach the release point D, the negative pressure present at the second openings 13 in the area of the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This results in the waste parts 9 being released or in an active repulsion of the waste parts 9 which can be received by a waste container. In the area of the release point D, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17 in addition to the waste parts 9 .

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 1 to transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular suction gripper system 17 of the transport cylinder Ders 3 takes over the processed, in particular cut substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and has indentations at the points at which it acts on the blank 10 Mistake. Perforations are made on the one hand in the area of the panel 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 5, ie closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, ie closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3, the blanks 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, make contact with the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The residual webs that the waste parts 9 connect to the frame or to good parts 10, torn. The elevator 5 fixed on the stripping cylinder 4 has openings that correspond to the third openings 32 of the stripping cylinder 4 . The openings are formed in the region of the dressing 5 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 4 reach the tangent point B and face a respective panel 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force effect is developed that lifts the blanks 10 off the surface of the transport cylinder 3 . The negative pressure at the third openings 32 of the stripping cylinder 4 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 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e. for a few angular degrees, in particular 10 degrees of the rotary movement of the transport cylinder 3. This measure additionally supports the separation of blanks 10 and waste parts 9, since these are actively moved in different directions, at least for a short time. Preferably at the 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 9, which fixes the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. 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 9 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 3 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 3 in the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away hanging therefrom. The transfer of the blanks 10 from the transport cylinder 3 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 9 reach the release point D, the negative pressure present at the second openings 13 in the area of the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This results in the waste parts 9 being released or in an active repulsion of the waste parts 9 which can be received by a waste container. In the area of the release point D, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17 in addition to the waste parts 9 .

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 1 to the transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, holds the processed substrate sheet, in particular the cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings. The openings are introduced at the points in the elevator 5 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 3, 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 benefit 10 or only the waste parts 9 or the benefit 10 and the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. As a result of the further rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 pass the tangent point B. The waste parts 9 or the blanks with other elements do not come into contact at the tangent point B. When the respective benefit 10 and the respective waste parts 9 reach the transfer point or transfer area C between the transport cylinder 3 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 benefit 10 and the waste parts 9 are no longer fixed and are thus released. The fixing of the front edges of the substrate sheet 1 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 9 and the frames of the substrate sheets 1, including the front edges of the substrate sheets 1, which are still connected to one another by the remaining webs (complete sheets), are removed from the transport cylinder 3 in 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 the blanks 10 and the waste parts 9 and the frames of the substrate sheets 1 including the front edges of the substrate sheets 1 as a whole sheet from the transport cylinder 3 to the transport belt 29 can be supported 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 the stripping cylinder 4, 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 3 . The conveyor belt 29 is assigned to the stripping cylinder 4, 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 4, 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 4 and the stripping cylinder 4 is assigned to the transport cylinder 3 in the 12 o'clock position of the transport cylinder 3 . 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 4 . 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 sheet 1, waste parts 9 or blanks 10 in the transfer point 38 or transfer area between the conveyor belt 29 and the stripping cylinder 4 from the stripping cylinder 4 and transporting them further. Another transport system can be connected to the conveyor belt 29 , for example in the form of a further conveyor belt 30 . Preferably between between the conveyor belt 29 and the further conveyor belt 30 an overlapping area is formed, in which functionally processed substrate sheets 1 or blanks 10 and/or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30. It goes without saying that instead of the additional conveyor belt 30, another suitable transport system can also be configured that accepts processed substrate sheets 1 or blanks 10 and/or waste parts 9 from the conveyor belt 29. In addition to the conveyor belt 29, another transport system 76 can also be assigned directly to the transport cylinder 3, i.e. forming a transfer area or transfer point between the transport cylinder 3 and the other transport system 76 for processed substrate sheets 1 or panels 10 and/or waste parts 9. 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 5 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 blown air supply when the respective third openings 32 reach a third release point as a result of rotation of the stripping cylinder 4 about its axis of rotation, in particular the transfer point or transfer area between the stripping cylinder 4 and the 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, it being possible for the at least one rotary slide or the at least one rotary inlet to be formed on the end face of the stripping cylinder 4 . Like the transport cylinder 3 , the stripping cylinder 4 preferably has means for fixing an exchangeable elevator 5 . The means for fixing are preferably designed as clamping grippers. With them, a respective lift 5 can be fixed at the rear edge and at the front edge. The means for fixing the front edge of the dressing 5 are preferably formed by the clamping element front edge 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 4 . 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 packing 5 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 4 are in 10 and the associated description, to which reference is made in connection with the exemplary embodiment described. An elevator 5 with openings is preferably fixed on the stripping cylinder 4 . The openings in the lining 5 of the stripping cylinder 4 correspond to the third openings 32 of the opening cylinder 4. The openings are preferably formed in the area of the lining 5 where it is not raised and interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and face a respective panel 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force effect is developed that lifts the blanks 10 off the surface of the transport cylinder 3 .

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 1 to the transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, holds the processed substrate sheet, in particular the cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and has indentations at the points at which it acts on the blank 10 Mistake. Perforations are preferably made on the one hand in the area of the panel 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 5, ie closed. On the other hand, openings are preferably also in the area of the waste parts 9 introduced at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the region of the waste parts 9 being covered by the elevator 5, that is to say they are closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3, the blanks 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, make contact with the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The residual webs that the waste parts 9 connect to the frame or to good parts 10, torn. The elevator 5 fixed on the stripping cylinder 4 has openings that correspond to the third openings 32 of the stripping cylinder 4 . The openings are preferably formed in the region of the dressing 5 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 4 reach the tangent point B and are opposite a respective panel 10 at the tangent point B or directly in front of it, a negative pressure is applied to them. As a result of this negative pressure, a force effect is developed that lifts the blanks 10 off the surface of the transport cylinder 3 . The negative pressure present at the first openings 12 of the transport cylinder 3 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 3 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 9 are held on the surface of the transport cylinder 4 and transported past the tangent point B, while the blanks 10 are transferred from the transport cylinder 3 to the stripping cylinder 4 at the tangent point B. As a result of its rotation, the stripping cylinder 4 transports the blanks 10 fixed by vacuum further in the direction of the conveyor belt 29 until they reach the transfer point or transfer area E of the stripping cylinder 4 and the conveyor belt 29 . In the transfer point or transfer area E of the stripping cylinder 4 and the conveyor belt 29, a suction effect is preferably exerted on the side of the blank 10 facing away from the stripping cylinder 4 by the transport 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 4 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 the 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 9, which fixes the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. 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 9 at the target point A or immediately thereafter. When the waste parts 9 reach the release point D, the negative pressure present at the second openings 13 in the area of the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This results in the waste parts 9 being released or in an active repulsion of the waste parts 9 which can be received by a waste container. In the area of the release point D, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17 in addition to the waste parts 9 .

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 1 to the transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, holds the processed substrate sheet, in particular the cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs Transport cylinder 3 carries an elevator 5. The elevator 5 has openings. The openings are introduced at the points in the elevator 5 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 3, 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 benefit 10 or only the waste parts 9 or the benefit 10 and the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. When the respective blanks 10 and the respective waste parts 9 reach the tangent point B as a result of the further rotation of the transport cylinder 3, 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 benefit 10 and the waste parts 9 are no longer fixed and are thus released. The fixing of the front edges of the substrate sheet 1 by the gripper system 17 is also canceled at the tangent point B. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite a respective panel 10 at the tangent point B or directly in front of it, a negative pressure is applied to them. As a result of this negative pressure, a force effect is developed that lifts the blanks 10 off the surface of the transport cylinder 3 . The negative pressure present at the first and/or second openings 12, 13 of the transport cylinder 3 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 9 and the frames of the substrate sheets 1, including the front edges of the substrate sheets 1, which are still connected to one another by the remaining webs (complete sheets), are removed from the transport cylinder 3 at the tangent point B lifted and transferred to the stripping cylinder 4. The transfer of the blanks 10 and the waste parts 9 and the frames of the substrate sheets 1 including the front edges of the substrate sheets 1 as a whole sheet from the transport cylinder 3 to the stripping cylinder 4 can be supported by applying an 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 4 transports the complete sheets fixed by vacuum further in the direction of the conveyor belt 29 until they reach the transfer point or transfer area E of the stripping cylinder 4 and the transport belt 29 . In the transfer point or transfer area E of the stripping cylinder 4 and the conveyor belt 29, a suction effect is preferably exerted on the side of the whole sheet facing away from the stripping cylinder 4 by the transport 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 4 to the conveyor belt 29 at 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 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 4, a peeling device 31 (also called a peeling device) is assigned to the transport cylinder 3, as shown in particular in FIG 14 is evident. The peeling device 31 preferably has a contact surface which extends in the direction of a virtual tangent applied to the transport cylinder 3 . 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 assigned to the transport cylinder 3, preferably in its 12 o'clock position or viewed in the direction of rotation of the transport cylinder 3, 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 3 .

The transport cylinder 3 and the optional stripping cylinder 4 can be designed according to those embodiments of transport cylinder 3 and stripping cylinder 4, as they are particularly in connection with the objects according to FIG 9 until 13 have already been described.

The peeling device 31 has the particular function of lifting processed substrate sheets 1, waste parts 9 or blanks 10 with the aid of the peeling device 31 from the surface of the transport cylinder 3 or the surface of the elevator 5 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 further conveyor belt 30, in which processed substrate sheets 1 or blanks 10 and/or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30.

It is self-evident that instead of the additional conveyor belt 30 another suitable transport system can also be configured, which takes over the processed substrate sheet 1 or panel 10 and/or waste parts 9 from the conveyor belt 29 .

Instead of the further conveyor belt 30, a container for receiving waste parts 9 can also be arranged under the conveyor belt 29.

In addition to the conveyor belt 29, another transport system 76 can also be assigned directly to the transport cylinder 3, i.e. forming a transfer area or transfer point between the transport cylinder 3 and the other transport system 76 for processed substrate sheets 1 or panels 10 and/or waste parts 9. 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 1 is preferably part of a sheet-fed printing press. The sheet-fed printing press can include one or more printing units 6 . More preferred are the in 14 . illustrated embodiment two processing cylinder upstream, between which the substrate 1 can be inserted, the substrate 1 undergoes processing when passing through effective tool parts in the cylinder gap from the group of cutting tools, punching tools, grooving tools, perforating tools. 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 1 to transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and has indentations at the points at which it acts on the blank 10 Mistake. Perforations are made on the one hand in the area of the panel 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 5, ie closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, ie closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which presses the blanks 10 on the lateral surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3, the blanks 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, make contact with the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The residual webs that the waste parts 9 connect with the frame or with good parts (panel) 10, torn. Preferably at the 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 9, which fixes the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. 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 9 at the target point A or immediately thereafter. As a result of the rotation of the transport cylinder 3 , the blanks 10 and the waste parts 9 are transported past the target point B until they finally reach the transfer point F between the transport cylinder 3 and the peeling-off device 31 . Before the respective blanks 10 reach the transfer point F between the transport cylinder 3 and the peeling-off device 31, the first air supply means 14 of the transport cylinder 3 switched 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 are pushed off the surface of the transport cylinder 3 or its elevator 5 to the extent that the overpressure builds up at the first openings 12 . At least the front edges of the blanks 10 , viewed in the direction of rotation of the transport cylinder 3 , protrude beyond the peeling device 31 in the radial direction of the transport cylinder 3 . The peeling device 31 aims into the gap formed between the front edges of the blanks 10 and the surface of the transport cylinder 3 or its elevator 5. As a result of the rotation of the transport cylinder 3, 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 9 terminated when the release point D is reached, but the lifting of the waste parts 9 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 1 is preferably also released by the gripper system 17 in addition to the waste parts 9 .

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 1 to transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings. The openings are introduced at the points in the elevator 5 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 3, 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 benefit 10 or only the waste parts 9 or the benefit 10 and the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. As a result of the further rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 pass the tangent point B. The waste parts 9 or the blanks 10 do not come into contact with other elements at the tangent point B. The stripping cylinder 4 is turned off from the transport cylinder 3. When the respective blanks 10 and the respective waste parts 9 reach the transfer point F between the transport cylinder 3 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. 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 9 and the frames of the substrate sheets 1 including the front edges of the substrate sheets 1, which are still connected to one another by the remaining webs (full sheet ), are no longer fixed and are thus released at the transfer point F and preferably lifted off the surface of the transport cylinder 3 or the elevator 5 in a targeted manner. The fixing of the front edges of the substrate sheet 1 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 3, the complete 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 1 to transport cylinder 3 at the tangent point A between transport cylinder 3 and the upstream sheet transport cylinder cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and waste parts 9 and blanks 10 connected to it by so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and is provided with indentations at the points where it acts on panel 10. Perforations are made on the one hand in the area of the panel 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panel 10 being covered by the elevator 5, ie closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, ie closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or are located exactly at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which vacuums the blanks 10 on the lateral surface of the transport cylinder 3 or fixed to elevator 5. As a result of the further rotation of the transport cylinder 3, the blanks 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, make contact with the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The residual webs that the waste parts 9 connect to the frame or to good parts 10, torn. The elevator 5 fixed on the stripping cylinder 4 has openings that correspond to the third openings 32 of the stripping cylinder 4 . The openings are formed in the region of the dressing 5 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 4 reach the tangent point B and face a respective panel 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force effect is developed that lifts the blanks 10 off the surface of the transport cylinder 3 . The negative pressure at the third openings 32 of the stripping cylinder 4 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 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e. for a few angular degrees, in particular 10 degrees of the rotary movement of the transport cylinder 3. This measure additionally supports the separation of blanks 10 and waste parts 9, since these are actively moved in different directions, at least for a short time. Preferably at the 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 9, which fixes the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. 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 9 at the target point A or immediately thereafter. As a result of the rotation of the transport cylinder 3 , the blanks 10 and the waste parts 9 are transported past the target point B until they finally reach the transfer point F between the transport cylinder 3 and the peeling-off device 31 . Before the respective blanks 10 reach the transfer point F between the transport cylinder 3 and the peeling-off device 31, the first air supply means 14 of the transport cylinder 3 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 are pushed off the surface of the transport cylinder 3 or its elevator 5 to the extent that the overpressure builds up at the first openings 12 . At least the front edges of the blanks 10 , viewed in the direction of rotation of the transport cylinder 3 , protrude beyond the peeling device 31 in the radial direction of the transport cylinder 3 . The peeling device 31 aims into the gap formed between the front edges of the blanks 10 and the surface of the transport cylinder 3 or its elevator 5. As a result of the rotation of the transport cylinder 3, 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 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 9 terminated when the release point D is reached, but the lifting of the waste parts 9 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 1 is preferably also released by the gripper system 17 in addition to the waste parts 9 .

Instead of the conveyor belt 29, the transport cylinder 3 can also be assigned a further transport system 76 directly, i.e. forming a transfer area or transfer point between the transport cylinder 3 and the further transport system 76 for processed substrate sheets 1 or panels 10 and/or waste parts 9. 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 1 in place. 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 which 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 1 are arranged. The substrates 1 are conveyed by the gripper bridges in the direction of transport to the delivery stack stored on, for example, a pallet or another type of transport base. 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 a safe transport of the substrates 1 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 across the width of the machine. Blow 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 1 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 1 from sticking together on the delivery stack, in the area of the delivery 99 there is preferably an unspecified release agent application device, in particular a powder device, preferably combined with a device for sucking off the powder.

In front of the delivery stack there is a braking device, not designated further, for decelerating the substrates 1 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 1, decelerated by the braking device, come into contact with front stops and are thus 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 1 to be processed lie as a substrate sheet stack in the feeder 7 and are separated from this substrate sheet stack and fed one after the other either to one or more printing units 6 and printed in them or, if no printing units 6 are provided, fed directly to the processing unit 46. The substrate sheets 1 are processed in processing unit 46. For this purpose, the substrate sheets 1 are introduced one after the other into a cylinder gap formed between two processing cylinders and punched in such a way that a stamped sheet (processed substrate sheet 1) is produced from each substrate sheet 1, which consists of at least one blank 10 and at least a waste part 9 and a frame enclosing it, the panel 10, waste part 9 and frame adhering to one another via material connections that are not 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 now processed substrate sheets 1 are preferably transferred to the transport cylinder 3 by a sheet transport cylinder at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system 17, in particular the suction gripper system 17, of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The transport cylinder 3 preferably carries an elevator 5. The elevator 5 has openings. The openings are introduced at the points in the elevator 5 at which openings 12, 13, in particular first and/or second openings 12, 13, are formed. Preferably, when the openings 12, 13 due to the rotation of the transport cylinder 3 to have passed the tangent point A 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 reduces the benefit 10 or only the waste parts 9 or the benefits 10 and the waste parts 9 is fixed to the lateral surface of the transport cylinder 3 or to the elevator 5. As a result of the further rotation of the transport cylinder 3, the waste parts 9, which are preferably fixed by the negative pressure, reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The material connections that have not been completely severed, the connecting the waste parts 9 to the frame or panel 10, separated, that is torn. It goes without saying that the raised areas of the elevator 5 can alternatively also be designed as recessed areas. In this case, the corresponding areas of the stripping cylinder 4 are preferably raised. The decisive factor is that the raised or recessed areas on the transport cylinder 3 and a demolition cylinder 4 assigned to it are designed in such a way that the material connections that are not completely severed are separated, that is, torn.

As a result of the rotation of the transport cylinder 3 , the blanks 10 and the waste parts 9 are transported past the target point B until they finally reach the transfer point F between the transport cylinder 3 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 9 reach the transfer point F between the transport cylinder 3 and the further transport system 76, the first and/or second air supply means 14, 15 of the transport cylinder 3 maintain the supply of suction air to the first and/or second openings 12, 13. Only when the waste parts 9 reach the release point D is the suction air supply to the first and/or second openings 12, 13 canceled or preferably switched to blown air supply, so that the waste parts 9 are released or preferably actively ejected.

In connection with the separating processes between the transport cylinder 3 and the stripping cylinder 4, it has proven to be advantageous in preferred embodiments to only remove selected material connections that have not been 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 panels 10 connected to it to maintain stability. Accordingly, it is preferably provided that the incompletely severed material connections between the rear frame part in the transport direction of the frame and the panel 10 are removed between the transport cylinder 3 and the stripping cylinder 4 and the incompletely severed material connections between the front frame part in the transport direction of the frame and the 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, between the transport cylinder 3 and the stripping cylinder 4 , the material connections that are not completely severed are maintained between a plurality of blanks 10 .

The method described above can be carried out in particular using one of the described embodiments of the device for treating substrates 1, in particular using the 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 3, which in its basic structure in the 2 illustrated transport cylinder 3 may correspond, so hereby in particular on the 2 and the associated parts of the description and in addition to the 3 until 8th including associated parts of the description. The transport cylinder 3 can be assigned a stripping cylinder 4, which in its basic structure in the 10 shown demolition cylinder 4 may correspond, so hereby on the 10 and the associated parts of the description.

The transport cylinder 3 and/or the stripping cylinder 4 preferably have means for fixing an exchangeable lift 5 in place.

In the case of a preferred embodiment with a transport cylinder 3 without an associated stripping cylinder 4, the means for feeding the replaceable elevator 5 are to the transport cylinder assigned to the 3. In the case of a further preferred embodiment with a transport cylinder 3 with associated stripping cylinder 4, the means for feeding the exchangeable packing 5 are associated with the transport cylinder 3 or the stripping cylinder 4 or both the transport cylinder 3 and the stripping cylinder 4.

The means for feeding the interchangeable dressing 5 include, if they are assigned to the transport cylinder 3, a pressing means 60 that can be selectively placed on and off the transport cylinder 3, in particular pivoted on and off, and if they are assigned to the stripping cylinder 4, a pressure means 60 on the stripping cylinder 4 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 3 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 roller is freely movable or, in a preferred embodiment, is motor-driven. More preferably, the roll or cylinder can also be assigned a motor that drives and/or brakes the roll 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 elevator 5 preferably include a guide roller 66, 67 and/or a guide rail 68, 69. More preferably, the at least one guide roller 66, 67 is associated with 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 5 can also include a store 72, 73 which is able to accommodate a plurality of elevators 5. The store 72, 73 is designed to store at least one elevator 5, while at least one other elevator 5 is arranged on the transport cylinder 3 or the stripping cylinder 4, with which the elevator 5 stored can be exchanged in alternation. The store 72, 73 is preferably able to accommodate, in addition to a lift 5 to be supplied, also a lift 5 which has been removed or is to be removed. The store 72, 73 preferably has different storage locations for an elevator 5 to be supplied and an elevator 5 to be removed.

Furthermore, the means for feeding the interchangeable dressing 5 can also have a device for pre-positioning, in particular positioning pins. The device for pre-positioning is preferably assigned to the memory 72, 73.

In order to arrange a dressing 5 on the transport cylinder 3 , the transport cylinder 3 is first rotated into a receiving position provided for receiving the dressing 5 . The rotation of the transport cylinder 3 can take place with the aid of an individual drive assigned to it or via a gear train which drives the transport cylinder 3 with other cylinders and drives it with a main drive. In the pick-up position, the means for fixing the front edge of the interchangeable dressing 5 are at least approximately opposite the store 72 . The lower edge of the elevator 5 to be fed (which corresponds to the front edge when it is fixed on the transport cylinder 3) 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 associated with the positioning in the elevator 5 correspond. If positioning pins are formed, the positioning recesses in the elevator 5 face the positioning pins and the elevator 5 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the elevator 5, the lower edge of the elevator 5 is released from the rail 72 by the rail 72 being pivoted or twisted by a motor or the front edge of the elevator 5 being lifted off the rail 72 manually. The pivotably mounted guard 70, 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 5 can be fed to the means for fixing the elevator 5. Once the leading edge of the elevator 5 has passed the access opening cleared by the guard 70 and guide roller 66, the guard 70 is pivoted back to its original position manually or by a motor such that the guide roller 66 contacts the elevator 5 and thus the elevator 5 on its way is guided to the nip formed between the jaw 22 and the cuff 24. The elevator 5 is preferably fed in by the force of gravity or, alternatively, motor-driven or manually. If the leading edge of the lift 5 the clamp gap has been reached, the lever 21 is pivoted and the front edge of the elevator 5 is thus fixed between the clamping jaw 22 and the impact 24 . The transport cylinder 3 is then rotated counterclockwise by a motor. When the front edge of the dressing 5 has moved under the pressure roller 60 as a result of the rotation of the transport cylinder 3, the linear drive 64 is activated. The linear drive 64 pivots the pressure lever 62 until the pressure roller 60 comes into contact with the elevator 5 and presses it against the outer surface of the transport cylinder 3 . The transport cylinder 3 is then rotated further counterclockwise by a motor and the packing 5 is pressed onto the outer surface of the transport cylinder 3 in the area of influence of the pressure roller 60 until the rear edge of the packing 5 reaches the clamping gap formed between the clamping jaw 47 and the impact 48. When the trailing edge of the dressing 5 is introduced 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 5 is to be removed from the transport cylinder 3 again, the pressure roller 60 remains pivoted away from the transport cylinder 3 . Either the leading edge or the trailing edge of the elevator 5 is released from the transport cylinder 3 and the transport cylinder 3 is then rotated so that the elevator 5 is conveyed in the direction of the store 72 again. Finally, the edge of the elevator 5 that was still fixed up to that point is released.

The arrangement of an elevator 5 on the stripping cylinder 4 is comparable to the arrangement of an elevator 5 on the transport cylinder 3, so that reference is preferably made to this unless differences are expressly described.

In order to arrange an elevator 5 on the stripping cylinder 4 , the stripping cylinder 4 is first rotated into a receiving position provided for receiving the elevator 5 . The turning of the stripping cylinder 4 can take place with the aid of an individual drive assigned to it or via a gear train which drives the stripping cylinder 4 with other cylinders and into which a main drive drives. The stripping cylinder 4 is preferably driven by an individual drive, whereas the transport cylinder 3 is driven via a gear train which drives the transport cylinder 3 to other cylinders and into which a main drive drives.

In the pick-up position, the means for fixing the rear edge of the interchangeable dressing 5 are at least approximately opposite the store 73 . The elevator 5 to be fed stands with its lower edge (which corresponds to the rear edge when it is fixed on the stripping cylinder 4) on a store 73 comprising holding pins 5 correspond. If positioning pins are formed, the positioning recesses in the elevator 5 face the positioning pins and the elevator 5 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the elevator 5, the bottom edge of the elevator 5 is released from the retaining pins by retracting the retaining pins or 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 5 can be fed to the means for fixing the elevator 5.

Once the trailing edge of elevator 5 has cleared the access opening provided by guard 71 and guide roller 67, guard 71 is pivoted back to its original position manually or by a motor such that guide roller 67 contacts elevator 5 and thus elevator 5 on its way is guided to the nip formed between the jaw 22 and the cuff 24. The elevator 5 is preferably fed in by the force of gravity or, alternatively, motor-driven or manually. When the rear edge of the elevator 5 has reached the clamping gap, the pneumatic muscle 25 is relaxed and the rear edge of the elevator 5 is thus fixed between the clamping jaw 22 and the impact 24 . The stripping cylinder 4 is then rotated clockwise by a motor. When the rear edge of the dressing 5 has moved under the pressure roller 61 as a result of the rotation of the stripping cylinder 4, the linear drive 65 is activated. The linear drive 65 pivots the pressure lever 63 until the pressure roller 61 comes into contact with the elevator 5 and presses it against the lateral surface of the stripping cylinder 4 . The stripping cylinder 4 is then rotated further in a clockwise direction by the motor and the packing 5 is pressed onto the outer surface of the stripping cylinder 4 in the area of influence of the pressure roller 61 until the front edge of the packing 5 reaches the clamping gap formed between the clamping jaw 47 and the impact 48. When the leading edge of the dressing 5 is introduced 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 5 is to be removed from the stripping cylinder 4 again, the pressure roller 61 remains pivoted away from the stripping cylinder 4 . Either the leading edge or the trailing edge of the elevator 5 is from the out breaking cylinder 4 is released and the breaking cylinder 4 then rotates, so that the elevator 5 is conveyed back in the direction of storage 73 . Finally, the edge of the elevator 5 that was still fixed up to that point is released.
