Definitions

  • the invention relates to a device for feeding empty bags a packaging machine with a bag stack feed, the at least has a holder for fastening a stack of bags according to the preamble of claim 1.
  • the empty bags are in stacks of about 50 to 100 pieces are summarized by means of a chain conveyor of the packaging machine fed.
  • the chain conveyor has bolts that as Serve holders and on which the stack of bags are hung. For this are the bags on their opening side with a protruding tab provided the corresponding holes corresponding to the bolts having.
  • the stack of bags is fed into the packaging machine with the chain conveyor into where the bags are filled individually and from Stack to be torn off. If a stack is torn empty, it drives Chain conveyor one cycle further and introduces the next stack of bags the packaging machine.
  • GB-A-1 188 352 discloses a device for feeding stacks of bags known to a packaging machine that a plurality of has tray-like carriers, each with the holder for attachment a stack of bags are provided as well as with the bag stack feed are releasably connected.
  • tray-like carriers By providing a larger number of tray-like carriers, can Several stacks of bags each for feeding to the packaging machine be prepared so that the operator only works again are needed when all carriers are empty. You can also larger stacks of bags are placed on the tray-like carriers so that the cycle time until the next stack of bags is introduced extended.
  • the memory is replaced by an exchangeable magazine formed in which several carriers can be accommodated simultaneously. So that is it is possible to prepare an appropriate magazine with filled carriers and replace the entire magazine on the machine. This requires considerably less time than exchanging each carrier individually.
  • the carrier is emptied in the packaging machine, and again separated from the bag stack feed. He can be stored again in a memory. It can be the memory for the empty carrier is the same memory, from which the full carrier was removed, but it is advantageous if the empty carrier after stack of bags is removed from it is stored in a further memory.
  • the respective stores can be moved transversely to the storage or retrieval direction, so that both the storage, as well as outsourcing at the same place in the device is possible.
  • the straps can always be straight into the memory be moved in or out of the memory without first need to be redirected on their way to their storage space.
  • the storage device can be a belt conveyor, for example act with two or four on the sides or corners of the wearer attacking conveyor belts move synchronously and the carriers crosswise can be pulled out to this direction of movement. It is but also possible, the individual carriers in the memory directly on top of each other to stack and not to hold on separate slide-in rails. However the carriers cannot separate from each other with separate slide-in rails snag so that they serve operational safety.
  • the carriers for the stack of bags are particularly characterized by that their length can be changed. This has made stacks out Bags with bottom fold have the advantage that the carrying length of the carrier so can be adjusted so that the thicker end of the bag on which the bottom fold is not on the carrier. This prevents that at the end of the stack there is a bulge projecting upwards forms when transporting the stack of bags into the packaging machine and could cause difficulties when filling the bags.
  • the carrier can consist of a smooth sheet that through slidable parts can be shortened, such as from the GB-A-2 088 334 is known.
  • are individual to adjust the carrying length Grate bars can be added on a base frame of the carrier or remove. It has the rust-like formation the advantage that the lying on the carrier Bag through a side retracting into the carrier Machine fork can be reached, so that the Then lower the beam and use a new, full one Bag carriers can be replaced without interrupting operations to cause because in the exchange period the remaining bags on the machine fork lie, be filled.
  • the carrier On the holder for attaching a stack of bags the carrier is advantageously a extending substantially perpendicular to the beam Pen that can be changed in length. Especially this pin can counteract the change in length Have spring element. In cooperation with a corresponding stop on the packaging machine is thus guaranteed that during the stack of bags is processed, the upper edge of the pen does not exceed the level of the top bag. This prevents the pen from entering the interior of the bag protrudes and to be inserted into the bag Can tear open products.
  • Figure 1 shows a feed device according to the invention from empty bags to a packaging machine, not shown.
  • the feeder is through a Protective grille 1 protected against accidental contact.
  • a magazine trolley as shown at the front with reference number 3, be driven into the device.
  • This magazine trolley shows in pairs on its narrow sides mutually assigned slide-in strips 4 on the tray-like described in more detail below Carrier 5 are pushed.
  • the tray-like carriers are checked beforehand by an operator with empty bags busy.
  • the correspondingly filled, inserted into the machine The carriage is then lifted by a 6th raised so that the bottom beam in the direction of the arrow 7 can be removed from the magazine trolley in order to use the To connect the bag stack feed to the packaging machine.
  • An infeed conveyor belongs to the stack of bags 8, which here as a linear longitudinal conveyor is formed, but also by a belt or Chain conveyor could be formed.
  • the carrier is along this infeed conveyor 8 the arrow direction 9 in a packaging machine, not shown introduced. There the carrier is in a bag removal position transported and the on the carrier located bags are filled and from Carrier removed by tearing.
  • the emptied carrier is then again along the direction of the arrow 10 conveyed back by the infeed conveyor 8 and as indicated by arrow 11 in another Magazine car 12 introduced, which also has a corresponding lifting device 13 in height to the Infeed conveyor is customizable.
  • the magazine trolley 12 is lowered or raised so that an empty tray-like carrier after the others placed on a pair of slide-in strips becomes.
  • the first magazine wagon lowered so far by the lifting device 6 that the the next carrier covered with bags removed and into the Packaging machine can be introduced.
  • the empty one Carrier becomes second magazine car 12 again transported.
  • the lifting device 13 places it on the floor and the magazine cart 12 can be operated by an operator be moved out of the device and through an empty magazine cart can be replaced.
  • FIG. 2 and 3 is a corresponding tray-like Carrier 5 shown.
  • the carrier has one rust-like bottom, which consists of several individual bars 14, which rest on a base frame 21.
  • This Individual rods 14 are laterally on pressure pieces at their ends 15 stored so that they can be easily installed or removed can be. This allows the support length adjust the carrier to the bags used. It should be borne in mind that the bags are attached to their closed end usually have a bottom fold and therefore are thicker there than on their other, open end. Because of the length adjustability the thicker end of the wearer hangs freely below and there is no bulge.
  • the tray-like carrier has at its front end Retaining pins 16 in which the stack of bags is suspended becomes. These retaining pins 16 are vertically resiliently mounted. As shown in Figure 4, the Carrier 5 namely during the processing of the bags gradually raised by a cam 17, so that the upper bag level always remains constant, So in the area of the filling mouth 18. Instead of one Cam would also be a spindle or the like possible.
  • the holding pins 16 When lifting, the holding pins 16 also travel upwards and would be less after processing Project the bag into the inside of the bag, i.e. the inside tear open the bag of products to be inserted. Therefore, a stop 19 for these retaining pins 16 intended. He is on the drawing with the filling mouth 18 and is located below the feed path 20 for the products to be packaged. It also hinders not opening the top bag because the top one Bag film is a little shorter than the lower one so not at all up to the holding pins and their stop protrudes. Thus the upper bag film can pass through a suction bar, not shown, or the like be lifted up while the one above lower bag wall still between stop 19 and retaining pins 16 remains fixed. After filling the The bag is then torn away, in the figure 4 So to the left, the film completely from the Holding pins is torn off. That it destroys it is not critical, because the edge of the bag is then is welded and separated.
  • the empty worked carrier is then lowered from the packaging machine, back into the appropriate magazine for empty carriers transferred and then together with this magazine for refilling moved out of the device.
  • FIGS. 6 and 7 there is a resilient holding pin 16 shown in more detail.
  • the holding pin is in a guide 22 out.
  • a dowel pin sits in this guide 23, which protrudes through two slots 24 of the holding pin 16.
  • Located in the hollow interior of the holding pin 16 a spring 25 between the dowel 23rd and the closed cover of the holding pin 16 sits.
  • the holding pin 16 is lowered, the slots slide 24 along the dowel 23 down, thereby the Spring 25 is compressed.
  • the spring 25 pushes him therefore back to its original position.
