Description

Technical Field

[0001] The invention relates to a stack cutting device having a first stack positioning device and a method for cutting a stack of individual sheets by means of the stack cutting device. Background Art

[0002] Stack cutting devices are used in particular for cutting stacks of individual sheets into stacks of printed sheets. Such stacks of printed sheets are, for example, stacks of securities, in particular stacks of banknotes. Alternatively, such stacks of printed sheets can also be stacks of labels or business cards. Devices are known by which the corresponding stacks of individual sheets are first cut at their edges and then cut into intermediate stacks, in particular in the form of strips, which are then cut into stacks of printed sheets.

[0003] DE 195 15 705 C1 discloses a stack cutting device having a stack support surface and a rotary punch pivotable about a vertical pivot axis for pivoting a stack of individual sheets, the rotary punch additionally being movable horizontally by means of a horizontal drive for horizontally displacing the stack of individual sheets.

[0004] Individual sheets that are stacked as flat as possible may lie in a wavy shape. In a stack of sheets, the sheets below are pressed flat by the layers above them. As a result, the sheets lying on top may be more wavy than the sheets lying below. The more wavy sheets have less horizontal stretch. If the edge of the entire stack is now cut off, less material may be cut from the top sheet than from the bottom sheet.

[0005] DE19843011A1 discloses a stack cutting device with a first stack positioning device, which has a cutting device for a stack of single sheets of paper, the cutting device having a tool beam with a tool, and the stack positioning device having a pivotable and vertically movable upper rotating punch and a horizontal drive device for moving the stack of single sheets of paper in a horizontal direction pointing from the upper rotating punch to the tool.

[0006] DE10124068A1 discloses a stack cutting device having an upper pressure plate on which an upper rotary punch is elastically supported. The rotary punch can be lowered onto the stack alone or together with the pressure plate. In addition, a clamp loading station is also arranged.

[0007] EP 1 593 467 A1 discloses a stack cutting device having an upper rotary punch and a lower rotary punch, which can be moved together in the horizontal direction in order to move a clamped stack of individual sheets in the horizontal direction.

[0008] A stack cutting device is disclosed by EP1504860A1, wherein the stack is moved to different knives on a circular trajectory without changing its orientation. In addition, a feeding device and a discharging device are also disclosed. Summary of the invention

[0009] The object of the present invention is to provide a stack cutting device having a first stack positioning device and a method for cutting a stack of individual sheets by means of the stack cutting device.

[0010] According to the invention, this object is achieved by a stack cutting device having a first stack positioning device and a method for cutting a stack of individual sheets by means of a stack cutting device.

[0011] The stack cutting device with a first stack positioning device has at least one first cutting device for cutting at least one stack of individual sheets, the stack cutting device has at least one supporting device with a first stack supporting surface, and the first stack positioning device has an upper rotating punch, which can be pivoted about a pivot axis which is particularly vertically oriented and can be moved in the vertical direction, the lower contact surface of the upper rotating punch is preferably arranged above the first stack supporting surface, and the first stack positioning device has at least one first horizontal drive for moving the at least one stack of individual sheets along and / or against the first horizontal direction. The first stack positioning device has at least one upper pressing element different from the upper rotating punch, in particular an upper pressing element, which can be moved in the vertical direction and is arranged to be movable along and / or against the first horizontal direction by means of at least one first horizontal drive, in particular in order to move the stack of individual sheets along and / or against the first horizontal direction. This offers the advantage that the stack to be cut can be handled very precisely, since a large number of work steps, such as cutting, turning or linear movement, can be performed without completely releasing the stack. This increases the accuracy of the transport and also allows the position of the sheet stack to be inferred solely from the movement of the corresponding components.

[0012] The first stack positioning device has at least two upper pressing elements, in particular gripper upper parts, which are different from the upper rotating punch, and the upper pressing elements can be moved with respect to the vertical direction and are arranged to be able to move along and / or against the horizontal direction by means of at least one first horizontal drive device, in particular with a stack of single sheets along and / or against the first horizontal direction. This provides the advantage that a more precise translation is achieved. In addition, the desired pivoting movement can be performed, for example, during the translation. In an alternative or additional improvement, the stack cutting device is preferably characterized in that the first upper pressing element, in particular the first of the at least two upper pressing elements, is arranged so that the upper pressing element can be moved along and / or against the first horizontal direction by means of the first horizontal drive device, and the second upper pressing element, in particular the second of the at least two upper pressing elements, is arranged to be able to move along and / or against the first horizontal direction by means of the second horizontal drive device. This enables the stack of single sheets to be aligned particularly quickly and accurately at a small inclination angle.

[0013] In an alternative or additional improvement, the stack cutting device is preferably characterized in that the first stack positioning device has a lower rotary punch that can be pivoted about a pivot axis and, for example, moved in the vertical direction. The upper contact surface of the lower rotary punch is further preferably arranged at the highest level of the first stack support surface. In an alternative or additional improvement, the stack cutting device is preferably characterized in that the first stack support surface has a lower rotary punch recess, in which the lower rotary punch is at least partially arranged. This increases the precision of the pivoting process, because the stack can be held between two elements that move together.

[0014] In an alternative or additional improvement, the stack cutting device is preferably characterized in that the first stack positioning device has at least one lower pressure element, in particular a gripper lower part, which is different from the lower rotary punch, and the lower pressure element is arranged to be able to move along and / or against a first horizontal direction, in particular to move the single-sheet stack along and / or against the first horizontal direction by means of at least one horizontal drive. For example, at least one lower pressure element can be moved with respect to the vertical direction. Then, each two pressure elements can, for example, form a corresponding gripper, which makes it possible to increase the precision of the translation process. In an alternative or additional improvement, the stack cutting device is preferably characterized in that each upper pressure element and the lower pressure element correspond to each other and together form a stack gripper, and the respective upper pressure element and the respective lower pressure element that together form the respective stack gripper are arranged to be able to move together along and / or against the first horizontal direction.

[0015] In an alternative or additional development, the stack cutting device is preferably characterized in that the stack cutting device has at least one first upper pressure plate, which is arranged to be movable in a vertical direction, and further preferably characterized in that at least a portion of the at least one first upper pressure plate is arranged in front of the upper rotary punch in a first horizontal direction, and at least a portion of the at least one first upper pressure plate is arranged in the first horizontal direction behind the upper rotary punch. This makes it possible to flatten the previously wavy upper layer of the sheet stack. As a result, the sheet is cut off by the respective cutter to a length that is preferably as large as possible, regardless of the height of the respective sheet in the sheet stack.

[0016] In an alternative or additional improvement, the stack cutting device is preferably characterized in that the minimum distance between the upper rotating punch and the corresponding at least one upper clamping element is a maximum of 100 mm, further preferably a maximum of 50 mm, further preferably a maximum of 30 mm, further preferably a maximum of 20 mm, further preferably a maximum of 10 mm, further preferably a maximum of 5 mm, and even further preferably a maximum of 2 mm, and / or the minimum distance between the lower rotating punch and the corresponding at least one lower clamping element is a maximum of 100 mm, further preferably a maximum of 50 mm, further preferably a maximum of 30 mm, further preferably a maximum of 20 mm, further preferably a maximum of 10 mm, further preferably a maximum of 5 mm, and even further preferably a maximum of 2 mm.

[0017] In particular, the stack cutting device realizes a method for cutting a stack of single sheets of paper by means of a stack cutting device, wherein the stack of single sheets of paper is first placed on a first stack supporting surface of a first supporting device, and in a first feeding process, the stack of single sheets of paper is moved along or against a first horizontal direction directed from the upper pressing elements to the first cutting device by means of at least two upper pressing elements acting vertically from above on the stack of single sheets of paper, and then, in a first lowering process, the upper rotating punch is lowered in such a way that the lower contact surface of the upper rotating punch comes into contact with the stack of single sheets of paper, and then, in a first releasing process, at least two upper pressing elements are moved upward and released from The upper rotating punch is lifted off the stack of single paper sheets, then, in a first pivoting process, the upper rotating punch is pivoted about the vertical pivot, thereby causing the stack of single paper sheets to pivot about the vertical pivot, then in a second lowering process, at least two upper pressing elements move downward and come into contact with the stack of single paper sheets, then in a second releasing process, the upper rotating punch moves upward and is lifted off the stack of single paper sheets, then, in a second feeding process, the stack of single paper sheets is moved along or against a first horizontal direction by means of at least two upper pressing elements, in particular vertically acting on the stack from above, and then, in a first cutting process, sub-stacks are cut out from the stack of single paper sheets by means of a first cutting device.

[0018] In an alternative or additional improvement, the method is preferably characterized in that, after the second feed process and before the first cutting process, during a flattening process, the upper rotary punch and / or the first upper pressure plate is lowered from above onto the stack of single sheets and comes into contact with the stack of single sheets.

[0019] In an alternative or additional development, the method is preferably characterized in that, during at least one operation, the stack of single sheets is moved along or against a first horizontal direction by means of at least two upper pressure elements and its orientation is changed in this process in that the at least two upper pressure elements are moved along or against the first horizontal direction to different extents while they move the stack of single sheets.

[0098] In an alternative or additional improvement, the stack cutting device 01 is preferably characterized in that the second cutting device 14 has at least one second upper pressure plate 64, which is arranged to be movable about the vertical direction V. The second upper pressure plate 64 is used in particular to compact the single-sheet stack 26 and / or the intermediate stack 28 to be cut, thereby ensuring that the individual single sheets 71 are layered as evenly as possible. The second upper pressure plate 64 is especially to be distinguished from the second cutting aid 24 and the at least one upper pressure element 58.

The working width of the first cutting device 13 is preferably greater than the working width of the second cutting device 14.

[0102] Preferably, the stack cutting device 01 is a stack cutting device 01 for producing stacks of securities. Such a stack of securities and / or the underlying sheet stack 26 preferably has a height of at least 10 mm, more preferably at least 20 mm and / or preferably at most 80 mm, more preferably at most 60 mm, more preferably at most 50 mm.

[0103] With the stack cutting device 01, a method of cutting a single-sheet stack 26 by means of the stack cutting device 01 can be performed. Here, the single-sheet stack 26 is first placed on the first stack support surface 04 of the first support device 11. For example, the single-sheet stack 26 is first placed in such a way that, when viewed in the direction of the conveying stroke, the front gripper edge 72 is in front. (This is also shown as an example in Figure 7a .) Preferably, the four edges are trimmed first. Here, it is advantageous that the corner 74 connecting the front gripper edge 72 of the single sheet 71 to the lateral gripper edge 73 of the single sheet 71 is used as a reference and is only changed with the last two cuts. For this reason, the single-sheet stack 26 is preferably first rotated by 180° and then conveyed into the first cutting device 13. (This is also shown as an example in Figure 7b .) Then, preferably, the first edge is cut there. Then, the stack is preferably rotated by 90° or slightly more. If necessary, a translational movement of the single-sheet stack 26 is now performed in order to correctly adjust the position of the single-sheet stack 26 relative to the first cutting tool 18. Thereafter, the first side edge can be cut. (This is also shown in Figure 7c by way of example.) Subsequently, the single-sheet stack 26 is further rotated by 90° or slightly less. Now, for example, the front gripper edge 72 is in front when viewed in the direction of the conveying stroke and can be cut after the translational movement of the single-sheet stack 26 to correct the position. (This is also shown in Figure 7d by way of example.) Subsequently, the single-sheet stack 26 is further rotated by 90° or slightly less. After a further translational movement, the lateral gripper edge 73 can now be cut. (This is also shown in Figure 7e by way of example.) For example, the single-sheet stack 26 is cut into a relatively small trapezoidal shape in this way. The above rotational movements are performed, for example, by means of at least one rotational punch 08; 29.

[0104] Subsequently, for example, the sheet stack 26 is cut into a plurality of intermediate stacks 28. For this purpose, the sheet stack 26 is transported, for example, in a first horizontal direction F. If necessary, the sheet stack is slightly rotated before and / or after and / or during the transport. For example, the rotation before or after the transport can be carried out by means of at least one rotary punch 08; 29. ​​The rotational movement during the transport in the first horizontal direction F can be achieved, for example, by an uneven, in particular different-length feed, by means of two upper pressing elements 31; 32 and / or two stack grippers 38; 39. It is therefore preferred that during at least one operating process, in particular a feed process, the sheet stack 26 is moved along or against the first horizontal direction F by means of at least two upper pressing elements 31; 32 and is thereby changed in terms of its orientation in that the at least two upper pressing elements 31; 32 are moved along and / or against the first horizontal direction F with different lengths when they move the sheet stack 26. Then, the intermediate stack 28 is cut. The sequence of feeding and cutting and optionally rotating in between is preferably carried out several times in succession, so that the entire sheet stack 26 is finally divided into a plurality of intermediate stacks 28. (This is also for example also in Figures 7f to 7i ) These intermediate stacks 28 are, for example, of slightly trapezoidal design and / or can then be cut into sheet stacks 27 , in particular stacks of securities, by means of at least one second cutting device 14 .

[0105] The method is described in more detail below, for example using the preferred stack cutting device 01. In a first feed process, the sheet stack 26 is moved by means of at least two upper pressure elements 31; 32 acting vertically from above on the sheet stack 26 along and / or against a first horizontal direction F directed from the upper pressure elements 31; 32 to the first cutting device 13. For example, the start of the first feed process is also Figure 8a In Figure 8a 39 fixes and / or presses, except for the first stack support surface 04, the sheet stack 26 is preferably only fixed and / or pressed by the stack gripper 38; 39. Figure 8a The situation shown is basically equivalent to Figure 7a The end of the first feeding process will be equivalent to something like Figure 8b Preferably, the upper rotary punch 08 is then lowered in a first lowering process in such a way that its lower contact surface 36 comes into contact with the sheet stack 26. The result of the first lowering process is also, for example, Figure 8b In Figure 8bIn the embodiment of the present invention, in addition to the first stack support surface 04, the sheet stack 26 is preferably held and / or pressed by upper holding down elements 31; 32 or stack grippers 38; 39 and by at least one rotating punch 08; 29. ​​At least two upper holding down elements 31; 32 are moved upwards and lifted off the sheet stack 26. In addition to the first stack support surface 04, the sheet stack 26 is preferably held and / or pressed only by at least one rotating punch 08; 29.

[0106] Preferably, in particular, in the first pivoting process, the upper rotary punch 08 is then pivoted about the vertical pivot 07 and the sheet stack 26 is thereby pivoted about the vertical pivot 07.

[0107] Preferably, in particular subsequently during the second lowering process, at least two upper pressing elements 31; 32 move downwards and come into contact with the sheet stack 26.

Preferably, in the second feed process, the sheet stack 26 is then fed by at least two upper hold-down elements 31; 32 in or against the first horizontal direction F. The result of this second feed process is also shown as an example Figure 8e In.

In this case, i.e., in particular after the second feed process, in a first cutting process, sub-stacks 42 are cut out from the sheet stack 26 by means of the first cutting device 13. The sub-stacks 42 correspond, for example, to the edge regions removed during the edge trimming process.
