Definitions
- the invention relates to a method and a device for separating unsized paper blocks with cardboard spines from a stack comprising a plurality of paper layers and cardboard intermediate sheets which are cut flush with their cutting surfaces.
- the paper layers each contain a counted number of paper sheets and are separated from one another by the intermediate cardboard sheets forming the back of the cardboard in the finished block. The separation is necessary for the further assembly of the paper blocks. So far, it was carried out by hand and was therefore labor intensive.
- the invention is based on the object of developing a method and a device which enables automation of the separation process.
- the solution according to the invention is based on the knowledge that the cardboard interleaves have, due to their inherent rigidity when bending, a multiple greater elastic restoring force than the paper layers, so that in the case of bending blades in a stack, entire layers are preferably returned to the stack under the action of the restoring force of the adjacent cardboard interleaf Valves.
- By suitably aligning and positioning bending forces acting on the cut surface of a stack it is achieved according to the invention that the last paper layer covered by a cardboard end sheet is spread apart from the rest of the stack. By penetrating the resulting gap, the paper block thus separated can be separated from the stack and fed to the further processing stations.
- the stack is advantageously pressed or held against the abutment during the bending process. In the case of higher stacks, this can only be done by acting on the dead weight. Expediently, however, the stack is additionally clamped in the vicinity of the abutment between two of its cut surfaces.
- the paper block can be peeled off from the rest of the stack for this purpose by engaging in the gap.
- the paper block it is also possible for the paper block to be gripped in the area of the gap by a gripper and removed from the rest of the stack, preferably pulled off or lifted off.
- an additional hold-down force is exerted on the bent paper layers, which is less than the restoring force of the cardboard intermediate sheets, but greater than that of the paper layers .
- a particularly light bending sheet with the lowest bending forces is possible in the area of the corners of the protruding stack part.
- the stack is located in a downwardly open shaft, which is bordered by vertical boundary walls or edges and which is at the bottom is limited by a carriage that can be moved horizontally back and forth on the machine frame.
- the carriage has abutment rollers for the stack and a device for peeling off the paper blocks bent by the separating head.
- at least one separating member which can be inserted into the gap formed by the separating head by moving the carriage, is preferably arranged as a roller or pair of rollers.
- two alternatingly operable separating heads are arranged on opposite sides of the stack, while the carriage has two roller groups as an abutment, which are arranged mirror-inverted to one another in the direction of displacement with respect to a transverse center line and separated from one another by a central gap.
- the abutment rollers that symmetrically delimit the gap also form the separating elements that can be moved into the gap.
- a conveyor device that receives and transports the separated paper blocks is arranged below the carriage.
- the separating device consists essentially of a arranged on a machine frame 31, downwardly open shaft 11, a horizontally back and forth under the shaft with pneumatic means 36, 42 carriage 18 and two arranged on opposite sides of the shaft 11, alternately with pneumatic means 56, 58 actuable separating heads 50.
- the shaft 11 can be loaded with a paper stack 10 via a feed conveyor, not shown, which can be controlled by a light barrier which responds to the height of the remaining stack in the shaft 11.
- the stack 10 lies at its lower end covered by a cardboard end sheet on the abutment-forming rollers 20, 22 of the carriage 18.
- the rollers 20, 22 of the carriage are mounted in a frame 24, which in turn is mounted such that it can be moved back and forth with liners 28 on running shafts 30 extending between the cross members 32, 34 fixed to the housing.
- the carriage is moved pneumatically with the aid of the pneumatic cylinder 42 arranged on a yoke 40, the piston rod 44 of which is connected directly to the carriage 18.
- the yoke 40 in turn, can be displaced to a limited extent along the running shafts 30 with the aid of the pneumatic cylinder 36 arranged on the machine-fixed crossmember 32 and its piston rod 38.
- the separating head 50 can be displaced linearly via the tabs 52 on the rod 54 under the action of the pneumatic cylinder 56 and is arranged on the machine frame so as to be pivotable about the axis of rotation 62 by means of the pneumatic cylinder 58 and the piston rod 60 articulated on the joint 61 on the displacement device.
- an opening 48 for the passage of the separating heads 50 is left out by using shortened abutment rollers.
- the rollers 20, 22 are arranged on the frame 24 in a mirror-symmetrical manner to form two roller groups 19 with respect to the transverse center line. Between the mutually facing rollers 20, which have a smaller diameter than the other rollers, there remains a gap 46, the significance of which for the separation of the paper blocks is explained in more detail in the following functional description in the context of FIGS. 3a to f.
- the stack 10 to be separated into paper blocks with cardboard backing consists of a large number of paper layers 12 which are cut flush with the edges and are separated from one another by intermediate cardboard sheets 14.
- the separating process takes advantage of the fact that the cardboard intermediate sheets have a much greater elastic restoring force than the paper layers due to their higher inherent rigidity during bending.
- the two separating heads take their retracted initial position, while the carriage standing on the left is in its end position with the yoke 40 advanced, in which the one separating roller 20 of the left roller group 19 into the previously by the Left separating head 50 engages formed gap 15 and the stack 10 rests on the right roller group 19.
- the carriage 18 is subsequently moved in the direction of the arrow 80, the paper block 12 'is peeled off from the stack 10 by the separating roller 20 and passes through the gap 46 in the carriage 18 into the ejection tray 68. From there, the paper block is conveyed with the aid of a conveying device 70 fed to the further processing stations.
- the carriage 18 finally arrives in the right end position shown in FIG. 3b, in which both the small pneumatic cylinder 36 and the large pneumatic cylinder 42 are fully extended and the straightening blocks 26 strike against the left-hand cut surface of the stack 10.
- the left roller group 19 forms the abutment on which the stack 10 rests so that the right stack part protrudes freely over the pair of rollers 20 forming the abutment edge.
- the separating head 50 is now displaced downwards in the direction of the arrow 82 against the cut surface of the projecting stack part, down to the position shown in FIG. 3c.
- the paper layers touched by the separating head are bent downward to form a gap 15 and leafed through under the action of the restoring force of the intermediate cardboard sheets 14 until in the lower end position only one paper layer 12 'with the cardboard end sheet 16 6 is bent downwards and the second last paper layer with the associated cardboard intermediate sheet 14 for Stack is folded back.
- a brush 64 arranged in this way on the separating head and engaging in the gap 15 ensures that the paper sheets of the bent paper layer 12 'are held down. 3c, the separating head 50 extends through the cutout 48 in the carriage 18.
- the separating head 50 is then pivoted with the aid of the pneumatic cylinder 58 about the axis 62 in the direction of the arrow 86 into the vertical position shown in dashed lines in FIG. 3d. There it is no longer in engagement with the paper stack and can therefore be moved into the upper end position with the help of the pneumatic cylinder 56 in the direction of arrow 88 in accordance with the state shown in FIG. 3e and then with the help of the pneumatic cylinder 58 in the direction of arrow 90 in the 3f inclined starting position can be pivoted.
- the carriage is then moved to the left in the direction of arrow 92 by means of the pneumatic cylinder 42.
- the bent paper block 12 'with the end sheet 16 is peeled off the stack and passes through the gap 46 into the collecting trough 68 underneath.
- the right roller group 19 then forms the abutment , on which the stack 10 rests with a stack part which projects freely to the left over the roller 20 forming the abutment edge. From here, the separating and separating process described above is repeated, this time under the action of the left separating head 50, until after the individual process steps have been completed, the state shown in FIG. 3a is reached again.
