Description

The invention relates to a method for folding a material section, which may be, for example, a printed paper sheet and in particular has been produced according to the below-mentioned production or separation process. In this case, a folding member is pressed in the region of a Sollfalzlinie against the cut material portion. Furthermore, the invention relates to a corresponding device for folding the material portion with a folding tool, which is engageable in the region of the Sollfalzlinie with the material portion in engagement. For this purpose, the folding tool is associated with a gripper or other driver for interaction. The driver is by means of an adjusting device with the material portion in operative connection settable or solvable by this.

Finally, the invention relates to a cutting and folding arrangement for sheet or sheet-like material, for example, printed paper web or printed paper sheet, wherein the aforementioned separating and folding devices are used.

In a method for producing individual, format-appropriate material sections, in particular paper sheets, from a web-like, for example printed object (object web), in particular a paper, cloth, plastic or metal foil web, at least one cutting means is used, with the individual of the object web Material sections are separated and then removed from the cutting means. In the course of the cutting process or the actuation of the cutting means while at least one driver is brought into engagement with the object web. In a corresponding device for separating individual, format-appropriate material sections of a web-like object (object web), a can be brought into operative connection with the object web cutting tool, and one or more transport or conveying means are arranged. The latter are designed to remove the separated material portion after the separation process by the cutting tool. The Transport or conveying means comprise at least one driver (4, 6, 20), which is designed to engage with and / or to detect the object web (1).

Folders are known, for example, for web offset presses. There is especially the execution as Klappenfalzapparat common. From a former, a strand or object web first passes into a cross cutter, which consists of an example, two-piece cutting blade cylinder, which operates against a three-piece folding blade. The latter is equipped for this purpose with three cutting strips made of elastic, but durable material. The cutting knife is toothed like a saw and performs a punching cut, in which the bow ends therefore also appear toothed after the cut. Characteristic of the Klappenfalzapparat is the type of fold by means of folding blade and jaw. For this purpose act after the cut, for example, a three-piece folding blade cylinder and a two-piece jaw cylinder together. The Klappenfalz arises because at the point of contact of folding blade and jaw cylinder the folding blade cam-controlled emerges from the periphery of the cylinder while a example multi-layered, cut strand package (bows) pushes into the likewise cam-controlled open jaw. The jaw, which consists of a sprung steel strip with counter bar, closes immediately and holds the (folded) product as the cylinder continues. After the folding operation, the jaw opens in turn cam-controlled, and in grooves of the cylinder engaging Abstreiferzungen remove the folded product from the cylinder surface and let it fall by gravity and centrifugal force with the Falzrücken leading into a paddle wheel, where the product is braked between the curved blades and designed scaled (see. Kipphahn (Editor): Handbook Print Media, Springer Verlag 2000, page 298-300 ).

In EP 0 335 190 B1 a folder with collecting and folding cylinder is disclosed. In addition to this cylinder, a cutting cylinder and a jaw cylinder are still arranged.

In EP 1 247 757 A1 a sheet-fed folding device is described with a saddle-shaped folding blade on which the signatures are folded in a continuous. The folding blade has a stationary, inner guide member which cooperates with an outer follower folding member in the form of a revolving conveyor belt for folding the signatures.

DE 29 17 616 C2 describes a folding blade drive having a traveling linear motor. For each stroke movement of the motor secondary part of a folding blade is pressed down and with him a sheet to be folded between two folding rollers with fixed axes of rotation. The two opposite folding rollers transport the folded sheet on. A substantially similar fold arrangement is also in DE 198 43 872 A1 disclosed.

DE 10 2008 012 812 A1 describes a folding machine for a printing press. The folding machine includes, among other things, a folding cylinder, a holding cylinder, a conveyor belt section, a chopper folding device, two folding rollers and unloading conveyors. At the periphery of the folding cylinder, two pairs of folding blades are provided at intervals of approximately 180 °. Further, at the periphery of the folding cylinder, a needle device for web conveying and a separating blade for severing the web are provided. The folding cylinder pushes the needles of the needle device onto the top of the web and rotates while holding the web. The chopper folder includes, among other things, a chopper sword which is vertically reciprocated at a predetermined timing by a looping motion of a chopper arm.

In DE 100 55 582 A1 An apparatus and method for cutting a web for use in web-fed rotary presses is described. It should be possible to cut a web into signatures of variable section length. For this purpose, the device is provided with a plurality of linearly movable cutting elements for cutting the web in signatures and a plurality of gripper elements which cooperate with the cutting elements. The cutting elements are in Signature cutting area moved in a straight line in the web direction. The signatures are taken and the length of the signatures changed by controlling the distances between the cutting elements. Since the cutting elements and the gripper elements can enter the signature cutting area in a controlled manner, the signature length can be changed by controlling the distance between successive pairs of cutting and gripper elements in the signature cutting area.

DE 200 00 554 U1 describes a cutting press for cutting workpieces out of a foil. About a press table a height-adjustable cutting tool is arranged. On both sides of the press table shelves are provided for cut by the cutting tool punched parts. Two cutting tools are rigidly connected to each other and together can be moved transversely so that one tray is covered by a cutting tool when the other cutting tool is located above the press table. This should enable automatic stamped part removal at the highest possible production speed.

The German Patent 840,551 discloses an apparatus for incrementally advancing and periodically cutting a packaging tape in an automatic folding machine. After each cut-off operation and before subsequent advances, the portion of the tape to be cut by the following cut-off operation is automatically returned by an adjustable amount. Further, means for carrying out a control movement of constant amplitude and a loop-shaped slide rail are provided whose position is arbitrarily adjustable during operation. In the slide a shoe is arranged to perform reciprocating movements in the slide rail. This shoe transmits a component of the reciprocation to organs which engage the band for its return.

DE 101 33 213 A1 describes a separator for plate-shaped components. The separating device has a table-like shape. In the table top is a pivotable about its vertical axis turntable let in, which has a cutting gap, so that the cutting and breaking tools acting from above and from below onto the plate-shaped component to be separated carry out a longitudinal movement along the cutting gap. This should also allow an oblique to the transport direction of the component running section. The plate-shaped components are moved on an air cushion floating over the table surface.

From the GB 11,336 A AD 1914 a folding mechanism for printing machines is known, which has a folding knife. The folding knife inserts a bow into a gripping device and a reciprocating gripper folds the bow.

Especially in rotationally driven folders with rotating Schneidmesser-, Falzmesser- and Falzklappenzylindern results from the definition of the scope of the folding blade a determination on a specific, integer multiple of the folding format to be produced (section length). In particular, the folding blade cylinder and the cutting blade cylinder are realized as rotating components with fixed circumferential ratios. These are aligned with the associated jaw cylinder to a print format. The folding format or the section length, which is determined according to the distance of the cutting tools on the circumference of the cutting cylinder, so it is fixed once for the press once and then can not be changed.

In contrast, the folding method specified in claim 1 with the corresponding folding device according to claim 6 are proposed. In claim 12, an arrangement with a combination according to the invention of the severing or cutting device is defined with the folding device. Optional, preferred embodiments and embodiments of the invention will become apparent from the dependent claims.

The prior art design with cylinders whose circumferential proportions and arrangement of tools on peripheral portions define the machinable format is achieved by an assembly of tools and replaced tool carriers on linear guides and cross tables. These lie according to a preferred embodiment in pairs opposite each other and are each arranged next to the material web / object web. So their mutual, especially alternating action on the web is possible. On the basis of the optional use of multi-linear guides integrated in cross tables, arcuate movements can also be realized for the tool carriers. These can be synchronized in sections with the transport speed of the material web.

By in the invention, the coupling of a peripheral speed of a cylinder, such as cutting blade or folding blade, is resolved to the transport speed of a web, can be any variable section lengths or folding formats realize. This is made possible by the free movement control of the tools that are currently not in contact with the material web (for example, cutting knives, grippers or point needles) as well as their carriers and drive systems.

In the application of printing presses, the object to be processed can be taken from a known funnel apparatus. At the end of the severing and folding process, the folded products can be routed in the usual way to a paddle wheel or a belt delivery. With the invention, therefore, a flexibility of the folding system or apparatus can be achieved without changes to upstream or downstream system components are required.

The separating and folding arrangement according to the invention is suitable for any materials, in particular for those which can be transported only by application of a tensile force (for example paper, cloth, films).

The solution according to the invention is characterized in particular by the following aspects:

The invention provided for acting on the object path, according to the invention linearly guided tool elements are arranged in pairs, along and on both sides of this object path. Thereby, a mutual engagement, for example in the push-pull method, allows the tool elements on the object path. Only during the period of engagement in the object or material web, the relevant tool element must be moved synchronously to this. The linear guides for the folding blades and jaw grippers are also located on the left and right or on both sides of the (already cut) material section.

The drive system of the folding system according to the invention is realized essentially by linear drives. The corresponding linear axes or guides can be superposed on each other via several linear drives. As a result, curve-like movements or curved trajectories can be realized in one plane (according to the type of cross tables known per se). By superimposing, for example, two linear movements, a tool which is carried and guided in a two-axis guidance system, for example a cross table, executes any, even curved, curved movement path in a plane. There are sections of the movement path in which the tool held on the cross table should be in engagement with the material web. On these sections, the tools must move synchronously to the transport direction of the material or object web, otherwise they will tear them apart. On tracks without intervention, the tools can move asynchronously, since they are moved, for example, counter to the transport direction of the material or object web.

In the context of the invention, the tools for processing the object web or the separated material section are variably positioned by means of the linear drives replacing the Schneidmesser- and folding blade. The latter carry, for example, a cutting blade and the corresponding counter element, the cutting bar. The cut products (material section) are guided between parallel linear drives, for example with puncturing needles. When replacing the folding blade according to the invention and the other folding rollers by gripper or other Tool elements on linearly guided tool carriers can be realized by using the cross table principle even arcuate paths in sections synchronously to the material web or the material section.

The Schneidmesser-, Falzmesser- and Falzklappenzylinder used in per se known folders are inventively replaced by an arrangement with multiple linear drives. In particular, if these are provided with sliding carriage, can be realized by variable control different motion profiles, from which different section lengths or variable Falzformate can be derived. On the basis of the invention, the motion control for the object path or material section tools takes place independently of the object path, if they are not in engagement with the object path. This can be exploited to achieve flexibility and variability. Compared with the prior art, the following advantages can be achieved with the invention:

The folding format or the section length can be adjusted flexibly according to the user requirements. The section length can be changed even while production is running and can even be adjusted in a wide range.

With the replacement of the cylinders by linear drives, a reduction of the moving masses and thus a faster machine standstill is achieved. The security level is thus increased. In the case of a web break or web break (i.e., the object web is intentionally severed by separate elements in front of the folder), the linearly moving tool web engaging tool elements can be quickly opened and released from the object web. This reduces the amount of waste produced.

The movement principle generally used according to the invention is the synchronized, alternating holding and pulling the object web. The retention can be realized by puncturing needles, vacuum chambers, electrostatic membrane converters or even adhesive elements.

For supporting and guiding the object path tools and engagement elements, multi-axis drive and / or guide systems, in particular cross tables, can be used with several combined linear axes or guides. These run at an angle to each other, preferably 90 °, so that the plane of movement of the relevant, carried on the example cross table tool element is perpendicular to the plane which is defined by the transport direction of the material or object web and its width. The guided by multi-axis drive and / or guide systems tool elements can perform arcuate movements. Suitably, these systems, such as cross tables, arranged in pairs on both sides of the object path and can perform movements both synchronously and asynchronously to the object trajectory. A further preferred embodiment is that the multi-axis drive and / or guide systems, such as cross tables, are fixed to the frame with their respective longer axis. This minimizes the dynamic stresses caused by movement of the other axle and the tool parts carried thereon as well as the inertial forces to be overcome.

In order to achieve a coupling element between an active surface of the object web tool and the cross table or other multi-axis guide system, strips are arranged as support elements or other linear tool holders according to an optional invention example. Above this, e.g. Point needles or cutting or gripping elements each extend over the entire width of the material or object web. In the prior art, these strips are the respective tool holders on the tool-carrying cylinders of the folder.

In the context of the folding system according to the invention, a folding system control is provided which controls the movements of all cooperating in the folding machine axes simultaneously and has an interface to another higher-level control system of an entire system or machine, for example, higher-level printing machine. Through the interface can be a data communication between the Create folding system control and the higher-level machine control. As a guide, for example, the location of marks on the object web, which may be real (printed) or virtual, ie data technology implemented by software markers used. The term "virtual marking" comes from the context of the virtual leading axis known per se in modern printing presses, ie means a position marker that indicates the location of the web at a specific time and then from there via the location-time functions or the associated first three derivatives (speed, acceleration and jerk) of the local positions of the individual drives are determined. This marker, which can be visualized as a print mark on the material web, is renewed at regular intervals and, if necessary, corrections are calculated.

In the context of an optional invention training, the movement profile of the linear guides or linear axes is influenced with ramped inlets and outlets to bring about a synchronization on the position and speed of the object trajectory. Thus, a so-called "hacking" of the object web tools in the material or object web can be prevented. The web movement variables (web travel, web speed, web acceleration and web pressure) of the linear axes and guides are selected so that a so-called "flying" positioning of the tools to the material web is made possible, ie an asynchronous approach of a tool to the material web. From the engagement of the tool in the material or object web, the tool movement is synchronized with the movement of the material or object web to operate.

Servo linear drives are preferably used for the linear and XY stage axes. However, within the scope of the invention, ball-roller, roller-screw, threaded-spindle, spindle, rack-pinion, toothed-belt drives or even pneumatic or hydraulic drives would be practicable.

To prevent the collision of a specimen trajectory tool with an adjacent specimen trajectory tool, there is an optional Embodiment in a movement section "Platzschaffen". This means the movement of a tool and a tool carrier to avoid an adjacent tool.

Further details, features, advantages and effects, feature combinations and feature sub-combinations based on the invention will become apparent from the following description of preferred embodiments of the invention and the drawings. These show in each case a schematic side view in

• FIG. 1 the Gesamtfalzsystem with arranged in series separation device and subsequent folding device
• FIG. 2 an alternative embodiment of the separation device.

According to FIG. 1 In a transport direction A, a material or object web 1, for example printing material web, is supplied to the folding apparatus or system according to the invention. On both sides of the object web 1 cutting means 5, 7 are arranged in the transport direction A first, each of a fixedly supported lifting magnet 2 in a transverse direction Q transversely to the object web transport direction A with a predetermined movement stroke linearly back and forth are displaced. The cutting means 5, 7 comprise a cutting tool carrier 5 and one in the direction of the object web 1 projecting cutting blade 7. The mutual cutting means 5, 7 are arranged and driven along a linear guide axis y parallel to the transverse direction Q, alternately with the object web 1 this cutting to be brought into engagement in order to repeatedly cut and / or regularly cut off sheets or material sections 11 cut therefrom in a predetermined section length (folding format).

Furthermore, on each side of the object web 1 or of the cut material sections 11 or bows, a respective entraining device 4, 6 is arranged. The entrainment device comprises at least one puncturing needle 6 projecting towards the object web 1 and at least one cutting bar 8, which serves as a Counterelement associated with the aforementioned cutting blade 7. For this purpose, the cutting bar 8 can be formed elastically pressed by the cutting blade tip. The respective drivers 4, 6 are on a two-axis linear drive 2, 10, 9 in the manner of a cross table both along the object web 1 or cut sheets 11 and the material sections (linear guide axis x) and perpendicular thereto (linear guide axis y) adjustable. The two adjustment axes x, y are preferably located according to the cross table principle in a common plane and perpendicular to each other. The linear guide axis y perpendicular to the object web 1 or the cut sheet or material section 11 is realized by a solenoid 2 as the first linear drive. This adjusts the carrier 4 for the puncturing needle 6 and the cutting bar 8 with a predetermined movement stroke in such a way that the puncturing needle 6 can pierce the object lane and carry it along in the direction of the linear guide axis x along the object lane 1 or the material section 11. At the time of actuation of the cutting blade 7, the cutting bar 8 is available as a counterhold for the tip of the cutting blade 7, which separates the material sections or sheets 11 by means of adjustment by the lifting magnet 2.

To realize the driving function is parallel to the transport direction A extending linear guide axis x, along which a carriage 10 in a guide bed of a linear motor 9 controlled back and forth is movable. In this carriage 10, in turn, said lifting magnet 2 is mounted so as to be displaceable in a controlled manner perpendicular to the transport direction A (parallel to the above-mentioned transverse direction Q) in order to realize the linear guide axis y. The cutting strip 8 can be brought into engagement with the object web 1 or the cut material section 11 via the linear guide axis y in the position assigned to the opposite cutting blade 7 and the puncturing needle 6. By means of the linear guide axis x parallel to the transport direction A, the puncturing needle 6 can be actuated to remove the cut-off material section 11 from the cutting means 5, 7.

The double-sided two-axis linear drives 2, 10, 9, a pair of rollers 13, 14 is arranged downstream. Between the two rollers 13, 14 of the cut material portion is guided, with the respective driver 4, 6 can solve this. One of the two rollers is designed as a tension roller 13 and preferably driven by a servo motor with angle sensor. The second roller operates as a guide roller 14 and is linearly adjustable via a correspondingly adapted lifting magnet 3. The adjustment stroke runs in a linear guide axis y perpendicular to the transport direction A. Thus, the cut material portion 11 can be firmly grasped and guided in the pair of rollers. The roller pair 13, 14 is still a light sensor 15, for example, a light barrier downstream. This is designed to detect an initial edge of the cut sheet or material section 11 and deliver a corresponding output signal to a controller. If this control links this light sensor signal with the angular position value output by the angular position sensor of the servo drive of the tension roller 13, the controller can determine the position of the material section 11 and influence or readjust it by changing the speed or acceleration, for example.

Subordinate to the light barrier sensor are pneumatic suction and blowing elements 16 and 17, which serve to hold and guide the material section 11 for the subsequent folding by means of the folding blade 18 in a conventional manner. The latter is in turn displaceable via a linear drive in the form of a solenoid 2 in the transverse direction Q perpendicular to the transport direction A with a predetermined stroke. The displacement corresponds to the above-mentioned linear guide axis y. The displacement stroke of the folding blade 18 is dimensioned and aligned such that the folding blade tip between two guide strips 19 abuts the cut material section 11 in the region of a Sollfalzlinie in the receptacle of a gripper 20 into it. The latter can be actuated by a gripper actuator 21 for opening and closing. The gripper actuator 21 is mounted on a carriage 10 which is mounted according to the linear guide axis y and transverse direction Q perpendicular to the transport direction A in a linear motor 9 adjustable. The latter is fixedly supported.

The gripper 20 is a sheet delivery 22 downstream. By opening the gripper 20 by means of its actuator 21, the folded sheet 12 can fall on the sheet delivery 22 and be transported away.

To the movement of the overall arrangement after FIG. 1 the following is executed:

According to the in FIG. 1 drawn position are located just with respect to the transport direction A to the left of the object web 1 located cutting means 5, 7 and the right of the object web 1 located driver 4, 6 respectively in engagement with the object web. Complementary to this, the cutting blade carrier 5 with the cutting blade 7 has been retracted so that there is sufficient space for the right-hand driver 4, 6 in the case of the right-hand cutting means 5, 7. Conversely, the linksbefindliche cutting means 5, 7 is extended by the associated lifting magnet 2, while the left-handed two-axis linear drive 10, 9, 2 so far removed from the cutting point of the left-hand driver 4, 6 that the cutting process by the left-hand cutting means 5, 7 not disturbed. If the severing of the material section 11 from the continuous object web 1 is completed, the left-hand cutting means 5, 7 are again moved away or retracted by the associated lifting magnet 2 in the transverse direction Q, while the driver 4, 6 still in engagement with the severed material section 11 the right side is moved by means of its associated two-axis linear drive 9, 10, 2 from the cutting point in the direction of the actual folding station. Thus, alternately the left-hand cutting means 5, 7 and the right-hand driver 4, 6 on the one hand and the right-hand cutting means 5, 7 and the left-hand driver 4, 6 on the other hand with the material to be machined (object web 1, material portion 11) into engagement. Each in push-pull the two-sided two-axis linear drives 10, 9, 2 for the opposite-phase method of the associated driver 4, 6 and the two-sided cutting means lifting magnets 2 for the out of phase extension and retraction of the cutting means 5, 7, which coordinates of a folding control is.

In the course of further transport of the cut material sections 11 on the pair of rollers 13, 14 of the material section 11 enters the region of the folding blade 18 with associated, open and foldable gripper 20. This transport movement can be targeted by means of the draw roller 13 with extended by 3 in Control mounted roller 14 in operative connection with the light sensor 15 control, with the position of the material portions 11 can be calculated based on the output signals of the light sensor 15 and integrated in the servo drive of the tension roller 13 angle encoder in the control and taken into account. As a result, when the material portion 11 is pushed by the folding blade 18 in the gripper 20, so coordinated the hitherto applied guide roller 14 by means of the corresponding controlled lifting magnet 3 retract, so that sufficient material for the generation of the signature is free.

The embodiment according to FIG. 2 is different from the after FIG. 1 on the one hand by the special design of the cutting blade 7, by the blade shaft expires via a curved guide shoulder 24 in a pointed cutting edge 23. On the other hand, the puncture needle is after FIG. 1 replaced by an openable and foldable gripper 26, which is designed to detect the bent by the cutting edge 23 and the curved guide shoulder 24 of the cutting blade 7 out the starting edge of the separated material portion of the object web 1. To open and close the gripper 26 in turn serves a gripper actuator 21, which according to the gripper actuator of the folding blade associated gripper 20 FIG. 1 can be the same. Incidentally, the above statements apply to FIG. 1 here accordingly.
