Definitions

  • the invention relates to a device for the stacked stacking of bags made of plastic film and a method for operating such a device according to the features of the respective preamble of the two independent claims.
  • a device and a method for stacking bags made of plastic film are already known from DE 10 2011 1 3 569 A1.
  • the device has at least one traction means, preferably one or two toothed belts, wherein the device has at least one so-called cassette tray on which the bags can be placed flat on each other and which can be fastened to the traction means, wherein the cassette tray at least one means for clamping the launched Bag has.
  • the cassette sheets 8 are mounted, wherein three Kassettenbieche 8 are arranged at a distance side by side to form grooves 9. It has surprisingly been found in practice that the grooves 9 are not required.
  • the known cassette sheets 8 have an approximately U-shaped cross section, so that it results in a complex geometry with side walls and intermediate spaces, which makes the production consuming. A flat bearing surface is not given.
  • the overall structure of this known cassette tray 6 becomes even more complex in that the unit 10 with its cassettes 8 is mounted on a T-slot plate 3, wherein the T-slot plate 3 in turn is attached to the toothed belt 2 (see also Figure 14 together with the associated description DE 10 2011 113 569 A1).
  • the invention is therefore based on the object, the known device and the known method in terms of flexibility in the storage of plastic bags after they have been produced in a corresponding device to increase.
  • the device has at least one carrier, on which the bags are placed flat on each other, wherein the carrier is attached to the traction means, in particular a toothed belt, and that the at least one carrier at least one driver to take along the bag having.
  • both the carrier and the driver in their geometry can be made much simpler to realize the so-called cassette tray.
  • the carrier is designed for this purpose and is used so that the bags produced on it are placed directly on a flat support surface, thereby saving on the known cassette tray a component.
  • the carrier realizes a substantially completely flat support surface for the first bag, which is deposited there directly.
  • the flat support for the following bags is maintained in an advantageous manner, so that they can not deform disturbing in Aufiage Scheme, as in the Cassette storage due to the recesses forming the recesses according to the prior art is the case.
  • the carrier is designed substantially flat to form a flat bearing surface of the bag and / or the driver of the driver has an L-shape.
  • the substantially flat bearing surface of the carrier is optionally interrupted only by a narrow groove, in particular a T-slot (will be described below). The width of the groove does not cause deformation of the bags when placed on the carrier.
  • the device has two carriers arranged one behind the other, wherein a driver is arranged on each carrier.
  • the arrangement of the driver on the carrier is flexible, so that the driver can be moved relative to the longitudinal axis of the carrier.
  • two carriers, which adjoin one another and in which each carrier has a driver form a tray for receiving a plurality of stacked plastic bags. Due to the movable arrangement of drivers on their carrier any format of plastic bags can be adjusted. It is possible that the carriers are built narrow, so that a higher variety of formats is obtained. This is of particular advantage in the case of small bag formats, since the narrow construction ensures that the stacked plastic bags hang down laterally against the carrier.
  • the carrier has at least one groove, in particular a T-shaped groove which is viewed in its cross section, which cooperates with a fastening means, in particular a screw, and the driver. The extending in the direction of the longer longitudinal axis of the rectangular support surface of the carrier groove cooperates with the fastening means.
  • the head of a screw engages the T-slot in such a way that the screw in the groove is longitudinally displaceable for format adjustment but not rotatable about its own axis.
  • the threaded portion of the screw projects beyond the support surface and extends through the driver , More precisely through an opening (hole) in a foot of the wearer, wherein the foot rests flat on the support surface of the wearer.
  • a nut is screwed and tightened to set the driver in its desired position on the carrier for Formateinsteliung or loosened to move the driver relative to the carrier for the purpose of format change.
  • the L-shaped driver offers the advantage that it forms on the one hand a foot with an opening for the screw, wherein the foot is arranged directly on the carrier, and on the other hand has a projecting leg from the foot, which limits and guide for forms the bag to be placed and collected.
  • more than one extending in the longitudinal direction of the carrier groove may be provided, in which case the two or more than two grooves are arranged parallel to run in the carrier.
  • the tray according to the invention for the Kunststoffbeutei can be provided with known stacking pins, stacking sheets or other conventional Stapelhiifen and then works as a known pin stacker with inventive flexible storage for the plastic bag.
  • the tray according to the invention can also collect plastic bags that have no hole.
  • it has the advantage that due to the flat support of the stacked bags on the at least one carrier, the product can not be damaged or changed.
  • the drivers are arranged off-center with respect to the center axis of the carrier, so that the stacking position (also called saddle position) can be adjusted off-center to the stack of plastic bags.
  • FIGS. 1 to 5 An exemplary embodiment of a device according to the invention for the stacked stacking of bags made of plastic film is shown in FIGS. 1 to 5.
  • a device 1 is shown in various views for packet-stacking bags made of plastic film (not shown), the device 1 having at least one traction means, preferably a toothed belt 2.
  • the device 1 has at least one driver 3, preferably a plurality of consecutively arranged driver 3, which are attached directly or indirectly to the traction means.
  • FIG. 4 shows a partial view of the device 1, wherein it can be seen that the traction means (toothed belt 2) at least one, shown here several successively arranged narrow-building support 4 drives.
  • a driver 3 is arranged at a respective carrier 4.
  • each carrier 4 has its own driver 3. It is also conceivable that more than one driver 3, for example two drivers 3, are arranged on a carrier 4. It is important that each driver 3 is designed to be longitudinally adjustable relative to its associated carrier 4. Due to the flexible division of each driver 3 on its carrier 4 (or the distance between two drivers 3 on their common carrier 4), the support format for the plastic bag to be stacked can be adjusted.
  • the carriers 2 are, as shown, fiach founded and have a rectangular shape, wherein the upwardly facing surface forms the support area for the bags to be stacked, the bags are gradually placed after their preparation on the Aufiage Scheme.
  • a first bag is placed directly flat on the support area of the carrier 2 and the following bags are deposited au the previously pre-loaded bag until a stack of predetermined number of bags is formed, which can be removed.
  • the short side of the flat carrier (for example, with a height of 30 millimeters, preferably a maximum of 20 millimeters, more preferably less than 11 millimeters) is, for example, in the ratio 1: 3 to the long side.
  • the carrier 4 has at least one T-slot, which cooperates with a screw and the driver 3.
  • the extending in the direction of the longer longitudinal axis of the rectangular bearing surface of the support 4 T-groove cooperates with the fastening means.
  • the head of the screw engages in such a way in the T-slot, that the screw in the T-slot for the purpose of format adjustment is longitudinally displaceable, but not rotatable about its own axis.
  • the threaded portion of the screw protrudes beyond the bearing surface of the carrier 4 and extends through an opening (bore) in a foot of the driver 3, wherein the foot rests flat on the support surface of the carrier 4.
  • a nut is screwed and tightened to set the driver 3 in its desired position on the carrier 4 for the purpose of format setting or relaxed to move the driver relative to the carrier for the purpose of format change.
  • the traction means in particular the toothed belt 2, takes in a suitable manner each carrier 4, that is, the carrier 4 are driven and moved by the traction means. This is done by a drive 5 shown schematically.
  • the driver 3 has an L-shaped cross-section.
  • the one leg which forms a foot, with which the driver 3 rests directly on the support surface of the carrier 4, is preferably shorter than the upwardly projecting leg.
  • Same or reverse aspect ratios are also conceivable.
  • the protruding free end of a driver 3 may be chamfered (as in the left-hand carrier 3 in Figure 5) or not (as in the right-hand carrier 3 in Figure 5).
