- the present invention relates to a method for dividing a stack of sheets into reams of a predetermined number of sheets.
- Paper of a certain quality is known to have a uniform thickness. Stacks of paper of the same quality only differ in height if there are air gaps between individual sheets. Therefore, for stacking stacks of paper, it is known to compress the paper at one point with a certain surface pressure in order to then draw conclusions about the number of sheets based on the stack height. To separate a ream of a predetermined number of sheets, it is known to pierce the paper stack from the top edge of the paper stack at a height corresponding to the predetermined number of sheets and thereby separate the ream above it with a predetermined number of sheets from the remaining remaining stack.
- EP 1 264 792 A1 proposes a device for dividing a stack of sheets into individual sheets Number of sheets to use a sword to pierce the stack to be divided at a specified height from the top edge of the stack.

- the manipulation devices 11 are designed to transport a previously separated giant 3 with the gripping devices 8 in a first, linear transport direction 12, in the present case frontally forward, that is to say in the transverse direction of the stack 2.
- the first transport direction 12 runs essentially in a horizontal plane parallel to the side edges of the ream 3 or the stack 2. Accordingly, within the first transport direction 12, there is a relative movement of the ream 3 to the remaining stack 6, without there being any significant lateral overlap of the Giant 3 comes opposite the remaining stack 6.
- the manipulation devices 11 are also designed to move the gripping devices 8 laterally, that is to say in the longitudinal direction of the stack 2, in at least one second, also linear transport direction 13.
- the second transport direction 13 is aligned in a horizontal plane transversely to the first transport direction 12.
- the gripping device 8 can be moved in both transport directions 12, 13 described before the ream 3 is gripped and the ream 3 is transported with the manipulation device 11.
- the directions of movement 14, 15 of the two gripping devices 8 therefore correspond to the transport directions 12, 13 when transporting reams.
- At least one gripping device 8 can be moved laterally in the direction of movement 13 relative to the other gripping device 8.
- both gripping devices 8 can be moved laterally relative to one another in relation to the first direction of movement 14. This makes it possible to change the distance between the gripping devices 8 when changing the format of the stack 2 and adjust it to the new sheet format.
- the distance between the gripping devices 8 can be reduced and, conversely, increased if the stack 2 has a larger sheet format.
- the forks 9 of the gripping devices 8 can always be aligned parallel to the side edges of the giant 3 in the longitudinal direction.
- two gripping devices 8 are provided, with the lifting device 4 being arranged between the gripping devices 8.
- a separate manipulation device 11 is assigned or assigned to each gripping device 8 and the lifting device 4.
- the manipulation devices 11 are identical or have the same design.
- the manipulation devices 11 in the present case are articulated arm robots, the kinematics of which are made up of several arm members 16, 16a, 16b, 19, 21, 23 that are connected to one another in an articulated manner, with a gripping device 8 or the lifting device 4 being connected or held on a lowest arm member 16a is.
- the arm members 16, 16a, 16b, 19, 21, 23 can be rotated or pivoted relative to one another via rotation or pivot axes 16c, 17, 18, 20, 22, 25.
- the lowest, free arm member 16, together with the gripping device 8 or the lifting device 4, is connected to the second arm member 16a so that it can rotate or pivot about the rotation or pivot axis 16c.
- the second arm member 16a is rotatably or pivotally connected to the third arm member 16b about the rotation or pivot axis 18.
- the third arm member 16b is rotatably or pivotally connected to the fourth arm member 19 about the rotation or pivot axis 20.
- the fourth arm member 19 is connected to a fifth arm member 21 so that it can rotate or pivot about the rotation or pivot axis 22.
- the fifth arm member 21 is connected to a sixth arm member 23 so that it can rotate or pivot about the rotation or pivot axis 25. This achieves three-dimensional mobility of the gripping devices 8 and the lifting device 4.
- the gripping devices 8 and the lifting device 4 can be moved or moved in further directions of movement beyond the directions of movement 14, 15 shown in FIG or below, that is, in the vertical direction.
- the sixth arm member 23 is used to attach the articulated arm robot to a holding geometry of a carrier 24, for example via a screw connection.
- the articulated arm robot is a functional unit or assembly, wherein the movement sequences of the arm members 16, 16a, 16b, 19, 21, 23 are controlled and/or regulated with a control and/or regulating device, not shown.
- the pivot axis 25 is aligned obliquely backwards, for example by approximately 45 °, in the direction of a frame frame 26 with, for example, 4 vertical frame profiles 25a.
- the gripping devices 8 and the lifting device 4 can be pivoted into the interior of the frame frame 26. This ensures largely free access to the stack of sheets 2.
- Fig. 10 shows the device 1 according to the invention in a waiting and / or lifting position of the gripping devices 8 and the lifting device 4, the fork 9 and the lifting means 5 being arranged at a minimum height by pivoting up the lower arm members 16, 16a, 16b if necessary , which is a maximum Stack height, which corresponds to the height of the stack 2 before dividing the stack into a giant 3 predetermined number of sheets, exceeds by at least a quarter, preferably half of the stack height, more preferably at least 0.75 of the stack height.
- the gripping devices 8 and the lifting device 4, in particular the fork 9 and the lifting means 5, can be raised to an overhead height. It is not excluded that the gripping devices 4 and/or the lifting device 8 can be further raised with the manipulation devices 11, in particular in such a way that they are in a position that projects beyond the carrier 24.
- the manipulation devices 11 are held on the carrier 24, the carrier 24 being designed as a side arm on the frame frame 26.
- the carrier 24 protrudes or cantilevers over the stack 2 at least in some areas, preferably essentially.
- the adjusting device 27 can have a motor and a threaded spindle for height adjustment. If the carrier 24 is in the lower position, it is an operating or operational position. To maintain this position, locking means can be provided, for example extendable cylinders, in order to create a positive connection between the frame frame 26 and the carrier 24.
- the adjusting device 27 is preferably designed for vertical adjustment of the carrier 24 relative to the frame frame 26.
- the adjusting device has the adjustment device for guiding the carrier 24 relative to the frame frame 26
- the device 1 also has two camera devices 29.
- the camera devices 29 are held on the carrier 24.
- the camera devices 28 are aimed at the top of the ream 3 and monitor the position of the ream 3 relative to the remaining stack 6 during ream formation and/or ream transport.
- the image data recorded with the camera devices 28 can in particular serve as an input variable for a control and/or regulating device of the device 1, on the basis of which the manipulation devices 11 are controlled for moving the gripping devices 8 and/or lifting device 4.
- a counting device with a counting disk as lifting means 5 is provided as a lifting device 4.
- the counting device is rotatable and/or pivotable about the rotation and/or pivot axis 17 on the first arm member 16 of an articulated arm robot provided as a manipulation device.
- 11 manipulation device 25 rotation and/or pivot axis
- first transport direction 30 25a frame profile 13 second transport direction 26 frame frame
