Definitions

  • the invention relates to a device for producing and transporting stacks of film sections, in particular of plastic bags, with a step-by-step conveying device in which the film sections can be stacked on stacking pins.
  • Devices of this type are e.g. known from DE-OS 23 32 925, DE-GM 81 28 146, DE-PS 31 38 221 and US-PSn 4 252 333 and 3 555 977, both as single pins or as according to the US-PS as stacking pins 3 555 977 the legs of U-shaped brackets can also be used.
  • DE-OS 30 26 494 is concerned with the task of enabling fully automatic operation by using a rotary table-like stacking device.
  • the invention is based on the object of enabling a fully automatic removal of the stacks from the stack conveying device.
  • the invention is based on the known method, in which the transported stacks are attached to the legs of U-shaped brackets.
  • the stacking pins in the stacking device are formed by the legs of detachable brackets, only the stack formed in accordance with feature c) has to be removed from the stacking device together with the bracket in the removal station. It is therefore no longer necessary to move the stack from the stacking pins to the legs of U-shaped brackets, which is the main difficulty in the known devices when removing the stack from the conveyor track.
  • the invention also consists in specifying a device with the features mentioned at the beginning, with which the inventive method can be carried out in a simple manner.
  • the invention now achieves, in a surprisingly simple manner and with simple constructive means, that the stack of bags that has been moved into the removal station does not have to be lifted off the stacking pins and placed on a bracket.
  • the stirrups previously used for storing the stacks can now be fed to the stack conveying device in the stirrup delivery station and held there in the stacking position by the holding device.
  • the release device provided in the removal station, the holding device can be easily released and the stack held together by the bracket can be removed.
  • the invention also makes it possible to simplify the removal process even further in that a plug-on station is arranged between the stacking station and the take-off station next to the stacking conveyor device and is provided for plugging stacking lock washers onto the legs of the brackets. Because the stack is removed from the stacking conveyor together with the stacking pins formed by the legs of the clamped brackets, the locking washers can be attached to the stacking conveyor device before the stack is removed.
  • the stirrups lie on the saddle with the legs hanging down by means of the stirrup web, particularly easy handling of the stirrups when delivering to the stacking conveyor device is achieved.
  • the saddle can be designed as a molded part interacting with pulling strips and a hold-down device, by means of which a bracket can be bent from a piece of wire. To form this piece of wire, the end of a wire can be pulled over the saddle by a supply roller, cut from the wire and bent into a U-shaped bracket by means of the pulling strips and the hold-down device.
  • the first exemplary embodiment of a device according to the invention for producing and transporting stacks of plastic bags 11, which are provided with stack holes 12 (FIG. 2) at their opening edge, has the following stations in FIGS. 1 to 10: a welding station 13, in which the bags 11 (Fig.2) are made by making welds in a plastic web 11 'and by separating them, a stacking station 14, in which the bags are stacked into bags 15, and a take-off station 22, in which the stacks 15 can be removed from a stacking conveyor 21 during its standstill.
  • a bag conveyor 16 feeds the individual bags 11 separated in the welding station to the stacking station 14 one after the other and supports them there.
  • An impeller 17 in the stacking station 14 has vanes which are each formed by at least two suction arms 18, which extend radially from the impeller hub 19 and which are intended, when the impeller 17 is rotated, to remove the bags 11 fed by the bag conveyor 16 one after the other to take off this.
  • the stacking conveyor device 21 removes the stack of bags 15 stacked in the stacking station 14 step by step.
  • the stacking conveyor device 21 has carrier plates 23 which are connected at intervals from each other to a link 24 (see FIG. 1a) of an endless roller chain 25 which can be driven step by step by a drive motor 26 via a drive wheel 27.
  • Each carrier plate 23 carries under a cover plate 30 a detachable holding device shown in FIGS. 3, 4 and 5, which has a U-shaped bracket 29, the two legs 31 and a web 20 connecting them, releasably but firmly in a stacking position , in which the two legs 31 abut abutment surfaces 95, which are formed by the right end face in FIG. 3 of the support plate 23, and thus project upwards as stacking pins, so that in the stacking station the bags fed from the impeller from above onto these legs 31 can be stacked as stacking pins.
  • FIGS. 3, 4 and 5 On each carrier plate 23 of the stack conveyor 21 there is a holding device, which is shown in FIGS. 3, 4 and 5, FIG. 5 also showing a release device for releasing the holding device in the removal station 22.
  • the carrier plate 23 is arranged via a wedge-shaped spacer 32 on a base plate 33 lying horizontally in the upper and lower run of the stacking conveyor device, which is connected directly to the chain link 24 of the roller chain 25.
  • the carrier plate 23 with the cover plate 30, the spacer 32 and the base plate 33 with the chain link 24 form a transport link 91 of the stack conveyor 21.
  • each transport member 91 to form a releasable holding device for the bracket 29 are in each transport member 91 as tendons on the support plate 23 on the facing away from each other Sides of the strips 34 are arranged with the arms 37 and 38.
  • the arms 37 run parallel to the strips 34 and are connected at their ends to the support plate 23 so as to be pivotable about axes 39.
  • the angle levers 37, 38 form clamping surfaces 42 and insertion surfaces 43 which interact with the clamping jaw surfaces 35.
  • the arms 37 of the two angle levers are pressed in the direction of the strips 34 by springs 44.
  • the insertion surfaces 43 of the two angle levers diverge on the side facing away from the carrier plate 23 and are arranged such that when the legs 31 of a bracket 29 are brought up to the carrier plate 23 from above in FIG. 5, the arms 37 of the two angle levers 37, 38 be pushed apart. This opens a space between the clamping jaw surfaces 35 and clamping surfaces 42 for receiving the legs 31, in which the legs 31 are clamped by the force of the springs 44.
  • the clamping surfaces 42 of the two angle levers converge towards the side facing away from the carrier plate 23, so that they accommodate the receiving space close the legs 31 outwards when the angle levers 37, 38 of the action of the springs 44 are released.

  • the release device 60 has two angle levers with arms 45 and 46 which are pivotally mounted in their apices about axes 40. At the ends of the arms 45 there are rollers 47 which are provided as actuators for the interaction with the arms 38 of the angle levers 37, 38.
  • pins 49 of a link guide 51 engage in slots 48 and are fastened to the end of a piston rod of a lifting cylinder 52.
  • the arrangement is such that when the piston rod of the lifting cylinder 52 is extended, the angle levers 45, 46 are pivoted about their axes 40 so that the rollers 47 act as actuators on the arms 38 of the angle levers 37, 38 and the arms 37 about their axes 39 pivot away from the strips 34 so that the spaces in which the legs 31 of the bracket 29 are located open to the outside.
  • the stack in the removal station can be removed from the clamping device by simply pulling the stack.
  • the web of the bracket 29 is located in the removal station 22 at a distance below the stack, so that when the stack is pulled the bracket is tilted somewhat and is therefore easily pulled out of the tensioning device becomes.

  • This push-on device has two (FIG. 1) essentially vertical storage shafts 63, in which a supply of stacking lock washers 62 are arranged one above the other. Each storage shaft 63 opens into a horizontal feed channel 64, on the bottom of which the column formed by stacking lock washers 62 is supported, so that the lowest disk 62 is entirely in the feed channel 64.
