Definitions

  • the invention first relates to a method for stacking Bag made of a plastic film, in particular loop handle carrier bags, the finished welded bags or carrier bags individually in the form of scales filed, then grouped into stacks and finally one Storage are fed.
  • the invention has for its object a method of the type mentioned to propose and to create a device suitable for carrying it out, due to the or even with a comparatively high machine performance easier and more precise handling when collecting and stacking in packages of loot, bags or sacks is guaranteed, especially also if these plastic objects made of relatively thick plastic sheeting are manufactured.
  • This object is achieved in procedural terms in that the bags or carrier bags, one after the other, after a seam welding process and then transported in scales on top of each other, after which a gap in the shingled stream automatically due to an automatically triggered signal is generated and then in groups according to the respective gap summarized bags or carrier bags as stack packages immediately or indirectly to a removal area designed as a buffer section.
  • the cooling section to a certain extent represents, so that the welds have enough time to cool, which causes unwanted gluing and welding of the bags and carrier bags can be prevented in the area of their welds.
  • the additional cooling measure contributes to the fact that afterwards the bags or carrier bags are overlapping in a scaly shape be transported.
  • the storage device an intermittent transporting suction belt conveyor with at least twice the width of a bag or a carrying bag corresponding conveyor line, a subordinate and a scale flow belt conveyor controlled by a measuring device and a cooperating collating device and an immediate or indirectly connected take-off belt conveyor.
  • this preferably has several at a distance from each other arranged, endlessly rotating suction belts with funnel-shaped in a belt coating trained suction holes. It has been shown that through such a particularly high holding effect is achieved in the form of funnel-shaped suction bores.
  • the storage device such as. B. the suction belt conveyor and the shingled belt conveyor are coordinated.
  • the suction belt conveyor with an approximately the width of a Bag or a carrier bag corresponding conveyor section up to the area of the scale flow belt conveyor preferably arranged transversely to the suction belt conveyor which extends an endlessly revolving, depending on one by the Triggered triggering device with a periodically higher briefly higher Feed speed movable conveyor belt, above which a to End-to-end drive means belonging to the collating device, preferably a toothed belt is arranged on which a bearing block with a Area of the respective gap in the shingled stream in this retractable collecting finger is attached.
  • a further relief is if the take-off belt essentially parallel and slightly offset in the longitudinal direction to the conveyor belt of the Scale flow belt conveyor is arranged and further in the by the offset exposed area a transverse transport device is arranged, which is preferably has a gripper which can be actuated by a pneumatic cylinder-piston unit.
  • a finished stack can be relatively easily each Scale flow belt conveyor on the removal belt of the removal belt conveyor transport. Due to the offset of the two belts of the shingled belt conveyor and the take-off conveyor, there is an ideal opportunity in the freed Room an additional device, such as. B. a folding device and here in particular a folding device for a Z-shaped folding of the stack package generated in each case to accommodate.
  • Such a folding device has, for example, one on a first Locking arm fastened to the swivel arm and movable from above towards the stack and one attached at a distance to a second swivel arm from below Time delay to the locking rod on the folding rod acting on the stack package.
  • the storage device initially points behind a welding device 10 (FIG. 6) of a production machine, not shown Suction belt conveyor 1, the several spaced apart, endless encircling suction belts 2.
  • the suction belts 2 have a coating (FIG. 7) 3, in which funnel-shaped suction bores 4 are arranged.
  • loop handle carrier bags 5 are in the Way fed to the suction belt conveyor 1 that the carrier bags 5 on the lower strand of the Suction belts 2 individually one behind the other over at least two, preferably at least three times the width of a carrier bag
  • the section that serves as the cooling section is conveyed intermittently by the suction belt conveyor become.
  • a conveyor belt 6 of a scale flow conveyor 7 into it.
  • the loop handle carrier bags 5 with their Loop handle 8 ahead on the endlessly rotating conveyor belt 6 of the scale flow belt conveyor 7 filed in a stream of shingles.
  • a measuring device 12 On the side of the scale belt conveyor facing the suction belt conveyor 1 7 is a measuring device 12, for example an incremental encoder provided, the task of which is to drive the conveyor belt 6th to act on the scale stream conveyor 7 in such a way that the conveyor belt 6 after a certain preselectable number of carrier bags placed in a scale form 5 the conveyor belt 6 is accelerated forward so that in the shingled stream a gap designated 13 arises. In this way, the carrier bags grouped together.
  • a collating device 14 Above the conveyor belt 6 of the scale flow belt conveyor 7, a collating device 14 is arranged.
  • the collator 14 has an endlessly driven drive means, preferably a toothed belt 15 on which a bearing block 16 with one in the respective gap in the scale finger retractable collecting finger 17 is provided. With the help of Collector finger 17, the z.
  • a drive motor 18 is provided for driving the toothed belt 15.
  • the collating device 14 is shown in FIG. 2 for the sake of clarity omitted, as well as a transverse transport device 19 ( Figures 1 and 5), the is arranged behind the scale flow belt conveyor 7.
  • the cross transport device 19 is used to feed the individual stack packages to a take-off belt conveyor 21 transport, which is explained in detail in the manner described in more detail below becomes.
  • the transverse transport device 19 has a pneumatic cylinder 22 (see Figure 5) back and forth adjustable gripper 23.
  • the folding device has two swivel arms 26, 27, each extending substantially horizontally Pivot bearings 28, 29 can be pivoted over an area shown in FIG can.
  • Cylinder-piston units 31, 32 serve as the swivel drive the free end of the swivel arm 26, a locking rod 33 is provided by can be moved up to the stack is seated at the free end of the swivel arm 27 a folding rod 34 which can be moved up to the stack package from below and used at different times to the locking rod 33. This happens in the individual in such a way that first the locking rod 33 from above into the dash-dotted lines shown position is brought to a certain extent to represent a system or lock for the stack.
  • the Swivel arm 27 moves in the specified sense from below, the end part of the Package is folded around the locking rod 33. So the two rods are different long bags or tote bags can be customized, like the one in the drawing is indicated, the pivot bearings 28, 29 can be adjusted.
  • the pivot bearing 28 is on a substantially horizontal Slidable bearing carriage 35 arranged via a handwheel 36 and a Adjustment rod 37 is displaceable.
  • the pivot bearing 29 of the pivot arm 27 is on the other hand, displaceable on an inclined surface 38 by means of an adjustment slide 39 stored.
  • the respective end positions of the swivel arm 27 are through on the adjustment slide 39 arranged stops 41, 42 limited.
  • the individual stack packs 25 are spaced apart to each other on a comparatively large length and as Buffer section trained removal belt 43 of the removal belt conveyor 21, from where the stack packages can be packed by hand.
