Definitions

  • the invention relates to a device for removing V-shaped folding products positioned in a carrier structure.
  • Devices are already known from DE patents 36 21 832, 36 21 834, 36 21 822, in which folded products can each be positioned open upwards in a V-shape. It is also known from these patents to remove the folded products from the carrier structures, for example for storage or to mix folded products or to insert other folded products therein.
  • folded products 1 shows two multi-page sheets each folded, hereinafter referred to as folded products 1, 2, with pages 3 and 4 formed by a longitudinal fold and pages 5 and 6, respectively, and open pages 7 and 8 or 9 and 10.
  • the folded products 1 , 2 are different in height due to the different side designs at their four corners 11 to 14 and 15 to 18. If they were simply stacked on top of one another in accordance with the generally known prior art, these differences would add up, so that the stack becomes unstable, slips or tips over a certain height.
  • FIG. 2 shows how, after rotation of a folded product 1 by 180 ° and subsequent stacking, different corners come to lie on top of one another, as a result of which the differences in height and thickness differ compensate. If, in succession, every second folded product 2 is rotated by 180 ° in the direction of arrow 19 and, in addition, the folded products 1, 2 are inserted in a zigzag shape in the middle in the direction of arrows 20 and 21 according to the invention (FIG. 3 4, this results in the stable shape of a stack 22 shown in FIG. 4.
  • This stack 22 offers, for later sheet removal, access to closed folding edges 5 and 6, respectively, with the folding products 1, 2 opening in the middle.
  • FIGS. 5 to 18 A particularly advantageous possibility is described below with the aid of FIGS. 5 to 18, according to which folded products 1, 2 are combined in a zigzag-shaped carrier structure 23 as a preliminary step to the stack formation according to the invention, with folded products 1 opening upward in a V-shape are in the support structure 23 and are rotated 180 ° from a support structure 23 'folded products 2 placed on the folded products 1 in the support structure 23 or inserted like a comb.
  • Support structures of this type are known, for example, from DE patent 36 21 832.
  • FIGS. 5 and 6 schematically show the device for transferring folded products 2 from a carrier structure 23 'into the carrier structure 23 having the folded products 1.
  • the support structures 23, 23 ' as can be seen from FIGS. 5 and 6, are initially positioned in storage cartridges 24, 24' and are pulled out of these with the aid of preferably rotating drive devices 25, 25 'and 26, 26' and in cassette-shaped supports 27 and 27 'positioned. Due to the on the support structures 23, 23 'arranged tongues 28, 28' when pulling apart the support structures 23, 23 'the folding products located therein are opened in a V-shape upwards.

  • clamping beams 35, 35 ' are positioned above the support structures 23, 23', the function of which results from FIGS. 9 to 12.
  • FIG. 10 shows a side view of FIG. 9 again.
  • 9 shows a top view of a clamping bar 35.
  • the clamping beams 35, 35 'each comprise a carrier 36 which carries 37 rails 38 and 39 in guides.
  • Grippers 40, 41 are attached to the latter.
  • the rails 38 and 39 are moved in opposite directions against the pressure of a spring 43, for example a gas spring, by means of a pivot lever 42 with the aid of levers 44 and 45, as indicated by arrows 46, 47 in FIG. 9.
  • a spring 43 for example a gas spring
  • FIG. 11 which shows an enlarged section of FIG. 9
  • a pivoting lever 42 is brought into the position shown in FIG. 11 against the pressure of the spring 43 by a stationary pneumatic cylinder 48 or its piston the clamping bar 35 is arranged.
  • the pivot lever 42 can be locked by a bolt 49, which is moved by the piston of a stationary pneumatic cylinder 50 against the pressure of a spring 51 into the position shown in FIG. 11.
  • the pivoting lever 42 remains in its position after retracting or after the pneumatic piston 48 or the pneumatic piston 50 has been drawn in, since the spring 43 presses the pivoting lever 42 against the bolt 49.
  • the pneumatic piston 48 is moved against the pivot lever 42 and this is thus pressed into the position 42 ', the bolt 49 is released and pressed by the spring 51 into the position shown.
  • the spring 43 can move the rails 38, 39 in opposite directions in the direction of the arrows 52 and 53, so that the grippers 40, 41 are pressed against one another. This means closing the grippers 40, 41 with the aid of the spring 43.
  • arcs or can be between the grippers 40, 41 Folded products are held while the clamping beams 35, 35 'as a whole are moved by means of pins 54, 55 in guides 56, 57 by drives, not shown here.

  • the grippers 40', 41 ' dip into the support structure 23' and thereby capture the V-shaped folding products held open upwards in this by the tongues 28 'when the pneumatic piston 59 indicated in FIG. 7 , which corresponds in its function to the piston 48 (see FIGS.
  • the two-part support structures 23' can be moved laterally outwards, as indicated by the arrows 33, 34 in Fig. 7.
  • the tongues 28 ' release the folded products 2.
  • the tensioning beam 35 ' is now moved upwards with the V-shaped upwardly hanging folding products 2 in the direction of arrow 60 along guides 56, 57 and then in the direction of arrow 61 into the upper left position shown in FIG. 7 brought.
  • the clamping bar 35 'with the folded products 2 is located directly above the storage structure 23, in which the folded products 1 are also openly positioned in a V-shape, which is possible with the aid of the tongues 28 arranged on the support structures 23.
  • Below the clamping bar 35 ' is a second clamping bar 35 in the waiting position.
  • Both clamping beams 35 'and 35 are located according to FIG. 7 on an annular track or guide 62 which has a diametrically arranged guide.
  • the clamping bar 35 which is in the waiting position with the grippers open can be raised, so that its upward-pointing grippers 40, 41 each have one of the ones on the clamping bar 35' from below. hanging folded products 2 can capture.
  • the stationary piston 48 indicated in FIG. 7 is used in order to release the grippers 40, 41 from below for the purpose of detecting the folded products 2, so that the grippers 40, 42 are closed as a result of the spring action already described.

  • FIG. 24 shows a top view of FIG. 23.
  • the transport device 75 consists of two in total Gripper chains 76, 77, which can be roller chains, for example, and which run in guides 78, 79.
  • Their driver bolts 80 carry guide rollers 81 and drivers 82.
  • Gripper carriers 83 are screwed onto the latter.
  • Each gripper finger 84 is fixedly attached to a gripper carrier 83, while a second gripper finger 85 is pivotally mounted and can be controlled via a support roller 86 against the force of a compression spring 87 supported on the gripper carrier 83.
  • roller chains 76, 77 are supported on guide tracks 89, 90 by way of their guide rollers 81.
  • the carrier 27 with the carrier structures 23 that have moved apart is positioned under the transport device 75 such that, when moving upward in the direction of an arrow 74, preferably the sheet half of a leading folded product 2 penetrates centrally into a first opened folded product 1 (see FIG. 20) , wherein the sheet half of the folded product 1 also centrally between half of the leading, ie on the transport device 75 (Fig. 20) hanging folding product 2 is introduced.
  • a continuous i.e. receive a continuous arrangement of comb-like folded products 1, 2, so that a bumpless stacking and unstacking is possible, as described below.
  • a rail 91 with drivers 92 is lowered in such a way that it grips all the required gripper fingers 85 on its rear cam 94 with a movement in the direction of arrow 93 and thus opens for the takeover.
  • the rail 91 moves back into its starting position shown in FIG. 20 and the carrier 27 with the support structures 23 is likewise moved into the starting position shown in FIGS. 5 and 6, where after the emptied support structures 23 have been moved away, everything is ready for a new working cycle with the aid of a drive 26.
  • FIG. 25 shows a complete stack and the start of a stack 99 to the right of this stack already in a somewhat exploded view.
  • the interlocked folded products 1, 2 virtually form an endless, zigzag-shaped chain.
  • the grippers 84, 85 are kept closed by the tension of the compression spring 87. Only in the area of the lower deflection wheel 97 for the chains 76, 77 are the grippers 84, 85 opened by the curve 88 and place the folded products 1, 2 held in them cleanly on the stack 99 with the aid of a wiping tongue 98.
  • a tongue 101 should be temporarily pushed into position 101 'in order to positively influence the beginning of the stack, so that the first folded product is already deposited exactly on the pallet 96 or on the stacking table 110.
  • the positioning of the transport device 75 enables the stacks 99 to be produced to be formed close to one another on the pallet 96.
  • a sensor 102 is provided for this purpose, which scans the stack height and a sensor 103 measures the distance to the stack.
  • a sensor 104 detects the distance to the pallet and a sensor 105 detects the side edge of the stack (FIG. 28).
  • the constant stack height measurement controls the feed or the height of the lower deflection wheel 97 in the direction of an arrow 106 during stacking.
  • the position of the steering wheel 27 is adapted to the respective height of the stack when stacking and also when stacking.
  • a length compensation for the chains is required for this purpose, for which a deflection wheel 107 is provided, which moves during the movement of the deflection wheel 97 in the direction of arrow 106 for length compensation from its initial position 107 'in the direction of arrow 108.
  • the drive of the transport device 75 is initiated via a drive wheel 109.
  • the distance measurement to pallet 96 is used to determine the stack height, i.e. to determine the time at which a batch is finished, after which a next batch is started.
  • the table 110 on which the pallet 96 stands is moved in the X-Y direction via feed drives (not shown), i.e. in the direction of arrows 111, 112 (FIG. 28).
  • feed drives not shown
  • the sensor 105 controls the lateral distance to the stack 99 so that the transport device 75 or the gripper chain 75 always runs in the middle of the stack.
  • a controlled pickup 113 (FIGS. 26, 27) advantageously serves to pick up the sheet at the closed fold edge. It is driven cyclically via a crank mechanism 114 and is suspended at one end with a bearing pin 115 in a longitudinal guide 116, while the other, tapering end engages under an arch edge and thus raises it at the level of the grippers 84, 85. Here they slide between the open grippers 84, 85, the tongue 98 preventing an excessively large projection.
  • the shorter gripper finger 85 viewed in the direction of rotation 117, runs ahead and thus past the edge of each folded product which is only picked up by the trailing, longer gripper finger 84.
  • Each folded product is then inserted deep between the open grippers 84, 85 as the process progresses.
  • the course of the sheet edge or the edge of the folded product is indicated in FIG. 27 by a circular arc 118.
  • the special design of the pick-up 113 also allows the last half of the sheet to be picked up from the pallet surface.
  • the sensor 104 constantly scans the pallet surface.
  • the first receiving edge of a folded product when destacking at the beginning (fresh) sheet stack preferably consists of a closed folded edge, i.e. from a fold back.
  • the last half of the sheet to be recorded is forced to open to the front (FIG. 27).
  • the recording is only supported here in this last half of a folded product by a pivotable bracket 119 with a spherical head 120 which penetrates from the curvature 121 of the last half of a folded product into its position 119 'or 120' and enables secure recording ( 27, 28). You can then begin to destack another sheet stack.
  • edges of a folded product to be picked up are always closed folded edges or folded backs, and on the other hand, as a result of this comb-like connection or concatenation when storing the folded product and when picking up the folded products by grippers with the help of opposing ones closed arch edges 122 tensile forces in the direction of arrow 123 arise, which always press the front edge of a folded product against the tongue 98 and thereby enable exact and safe stacking with a clean stack edge of the folded product tray and a secure pick-up of the folded products with the aid of the grippers 84, 85 when processing a stack 99.
