Definitions

  • the invention relates to a device for forming stacks from successively conveyed flat workpieces, preferably bags, with an up and down moving stamp of the workpieces from their conveying plane onto a stacking plate or the stack pressing on it, in which the stacking plate is under pressure the deposited workpieces can be lowered and lifted according to the growing stack height.
  • the object of the invention is therefore to provide a device of the type specified at the outset, in which the stamp always applies approximately constant force to the workpieces to be stacked.
  • this object is achieved in a device of the generic type in that the stacking plate can be lowered against the force of a brake.
  • the stacking plate is thus supported on a brake which holds it with approximately constant force, so that the stacking plate can be pressed down by the stamp with constant force in accordance with the increasing stack height.
  • Conventional brakes with adjustable braking force can be used as the brake.
  • the stacking plate is expediently provided with at least one support or column guided vertically in a guide or bore fixed to the frame, on which a brake shoe engages with adjustable braking force.
  • the stacking plate can also be provided with a special rod or a strip on which brake shoes engage.
  • the stacking plate can or the like by a pneumatic cylinder. be raised, which raises it after formation and acceptance of a finished stack to form a new stack.
  • the Pneumatic cylinder engages on a support column connected to the stacking plate, which is guided in a guide of the frame and on which the brake shoes act.
  • the guide can consist of a bore of a guide piece fixed to the frame, which is provided with a transverse bore opening into the bore, in which the brake shoe is guided.
  • the brake shoe is expediently supported in the bore via a compression spring on an adjusting screw.
  • a row of needles fixed to the frame and penetrating the stacking plate into bores can be provided, onto which the stamp pins the workpieces to be stacked.
  • the needles can be heated to block the stack.
  • a conveyor 1, the bags 12 to be stacked are fed from a transfer conveyor, not shown, in the usual manner.
  • the conveyor device 1 consists of two perforated endless conveyor belts 2 which run around at a distance from one another and run over deflection rollers, of which only the deflection roller 3 is shown.
  • the two conveyor belts 2 rotating in parallel planes are perforated, the lower strands of the two conveyor belts running in a known manner over suction boxes 4.
  • In the Conveying device 1 is therefore a suction belt conveyor which conveys the lower strands.
  • the deflection roller 3 is held by the two side walls, of which only the side wall 5 is shown, and is mounted in these. Furthermore, an axis 6 and a shaft 7 are rotatably mounted in the side walls, wherein the shaft 7 can be rotated back and forth by means of a device, not shown.
  • Parallel links are placed on both the axle 6 and the shaft 7, the lower link being freely rotatable on the axle 6 and the upper link non-rotatably connected to the shaft 7.
  • the free ends of the parallel link 8 carry a plunger 9 which extends through the space between the two conveyor belts 2. With the lower end of this plunger 9, a holder 10 is connected, which carries a plate 1.
  • Both the holder 10 and the plate 11 are dimensioned so that they can be moved from the position shown in Figure 1 through the space between the two conveyor belts 2, the position shown in Figure 2.
  • the plate 11 presses an incoming bag 12 down onto a stacking table 13.
  • This stacking table is fastened to a support column 14, at the end of which is remote from the stacking table 12, the piston rod 15 of a pneumatic cylinder 16 engages.
  • the pneumatic cylinder 16 is firmly connected to a cross member 17.
  • a holding plate 18 is supported on the pneumatic cylinder 16, on which two supports 19 and 20 rest, which are firmly connected to a guide piece 21.
  • the support column 14 is guided in this guide piece.
  • the guide piece 21 is provided with a horizontally running bore, into which a Wroclaw piece 21, which partially surrounds the support column 14, is inserted.
  • the pressure with which the brake piece 24 rests on the support column 14 can be adjusted via a screw 22 and a spring 23. Pneumatics during the stacking process cylinder 16 is depressurized, so that regardless of the height of a package 24, the force to be applied by the parallel core 8 always remains the same. The force that the parallel links have to exert only has to be so great that it overcomes the friction between the brake piece 21 and the support column 14.
  • a row of needles 26 is provided on a traverse 25, which can protrude through holes provided in the stacking table 13 as well as in the stacking plate 11 and thereby connect the individual bags 12 of a package 24 to one another and block them together when the needles are heated.
  • the plate 11 is raised into the position shown in FIG. 1 and the piston 15 is extended. As a result, the bags are stripped from the needles 26 and can be removed from the stacking table.
