Definitions

  • the invention relates to a method for the orderly storage, storage and allocation of individual flat workpieces, preferably plastic bags, wherein the bags individually manufactured by a manufacturing machine according to the inventive method are stored so that they are stored in order, then individually and automatically to one Bag to be allocated to automatic filling machine.
  • the invention also relates to the devices required to carry out the method.
  • the bags are manufactured with an overlap at the mouth opening of the bag, which have two holes for receiving the bags, for example on pins, the bags being stacked, fixed with brackets or a stitching and thus placed in boxes.
  • Methods are also known in which, for example, by means of complex stacking and depositing devices Belt and belt conveyors equipped with tongs and grippers, the individual bags are fed loose and successively, for example, to a winding device, in order to be able to be stored wound up in roll form.
  • a considerable disadvantage of the above-mentioned methods is that a great deal of manual effort is required to fill the bags, in particular because the bags of flexible film which are stacked one on top of the other are only vacuumed with great effort due to static charge due to gluing, but also due to heavy sliding. Are stackable and the individual stacks themselves always tend to become so disordered that orderly storage and transfer of the individual bags from the stack to a filling machine, for example, is only possible manually.
  • Another disadvantage is that bags stacked one above the other, for example with a bottom fold or about a cord hem or other closing devices on the mouth of the bag can only be stacked in very small numbers, since the uneven bag thickness quickly makes the stack itself very uneven, so that orderly removal and continuous operation on the filling machine are not possible. For example, it is not uncommon for a pressure already applied to the bag to be applied in the stack in such a way that an orderly allocation is made very difficult.
  • a further disadvantage of bags bundled with an overlapping flap is that for removal from the stack the bags are either provided with perforations along the flap of the bags, or the perforation has to be specially designed for tearing. If this perforation is too weak, the individual bag is difficult to separate from the stack; if it is too strong, there is a risk that the next or even several bags will also be separated. Here, then, considerable demands are placed uality both to the execution as q and to the films.
  • Another disadvantage of stacking the bags on pens is the considerable outlay in regulating and control devices for placing the bags on the pens, since both the longitudinal and transverse directions of the bag must be positioned, and the perforation partly symmetrical on the bag, on the other hand in Ab-. depending on the position of the pins must be attached in order to automatically attach the bags. Furthermore, considerable effort is required to remove, secure and pack the stack of bags.
  • the winding of the bags one after the other with or without a carrier tape to a roll has the disadvantage that for Achieving clean windings requires a certain train which can be controlled according to the roll diameter, ie the individual bags are subjected to different loads within the roll, which leads to the bags being warped and wrinkled. If the rolls are wound too loosely, there is a risk of the entire roll falling apart, for example during transport, if the rolls are rolled too tightly, the bags will crumple or stick together, or the print will be damaged.
  • a further disadvantage is that individual bags cannot be sorted out within the roll or can also be checked without the entire roll being destroyed. The packaging and transportation of larger rolls is also cumbersome and time-consuming and therefore expensive. Thus, great technical effort when winding or putting down the bags, but also high demands on the film quality, lead to the costly procedure.
  • the invention is therefore based on the object of providing a method with which flat workpieces, in particular plastic bags, which have been prefabricated by a machine and ejected at a specific direction and speed, can be sequentially detected, stored and stored in a selectable large number in an orderly state , in particular bags with different thicknesses, such as bags with a bottom gusset or cord hem on the bag mouth, can also be processed, in addition, different formats can be run without long changeover times and in which the device can easily be used by others in a similar manner at any time Bag manufacturing machines can be coupled.
  • this object is achieved in that the bags, prefabricated by a known manufacturing machine and ejected at a specific speed and direction, in which, according to the method, protrudes beyond the one, preferably lower, side wall, individually and in succession, approximately against a stop transversely to Direction of ejection aligned, then put down and is preferably attached by welding in the region of the lower protruding side wall, then a certain preferably constant distance in the direction transverse to the direction of ejection and opposite to the opening direction of the bag, so that the next bag then on the pre-placed Bag is placed so that this can be attached with its beginning portion of the protruding side wall along the opening of the bag with the end portion of the protruding side wall of the pre-placed bag, then both bags connected to each other as which are transported so far that the end region of the protruding side wall of the last bag placed is again in the area of the fastening device in order to reattach the next bag thereon, so that in the further course of the
  • the ejected, aligned and deposited bag manufactured, ejected, aligned and deposited according to the proposed method can be fastened, for example, on a carrier tape and can be transported further as proposed, in such a way that the next bag on the carrier tape is fastened and transported in the manner according to the invention can be, so that in the further progress a kind of storage tape from scales attached to each other bags.
  • the fastening of the individual bag along the bag opening takes place in the region of the preferably lower projecting side wall in such a way that the fastening area is shorter than the bag width and corresponds approximately to the later package width.
  • the holes can also be produced in a simple manner by welding, so that the fastening of the bags and the punching can be carried out simultaneously.
  • the storage tape formed from the individual bags which are fastened to one another can be handled in a wide variety of ways without the individual bag in the dressing being able to become disordered.
  • the storage tape can be stored in a zigzag position in a transport box or rolled up and banded in handy sections or even wound up into a storage roll.
  • the individual bag can always be removed in an orderly manner at one end of the storage tape.
  • Another advantage is that finally long storage tapes can be reassembled into a continuous storage tape after being removed from the carton by simply connecting the end of one section of the storage tape to the beginning of the next, for example by sticking it with adhesive tape or welding it together1 , and so the filling machine does not have to be stopped.
  • Another advantage of the storage tape produced in accordance with the method is that the individual bags fastened in an orderly manner to one another can be safely and automatically allocated to the filling machine.
  • the foremost pouch can be securely grasped in an orderly position at the beginning of the storage tape and the pouch can thus be removed without the next pouch being carried along or shifted, specifically in that, depending on the scale-like arrangement, the following pouch is safe for so long can be held until the present bag can be completely removed.
  • the front bag in a simple manner, for example by Ab tear a previously attached perforation line along the mouth of the bag, but can also be removed by welding or cutting, whereby the following bags always remain in the dressing and can be reliably held mechanically, so that no high demands are placed on the quality of the perforation line or on the film Need to become.
  • Another advantage of the method according to the invention is that the additional device required for the production of the storage tape can be used very simply and very universally on all known production machines.
  • the known devices for forming stacks etc. are always much more complex in that both longitudinal and transverse pouches must be positioned in order to reliably stack the bags congruently.
  • it is only necessary to align in the transverse direction advantageously by means of a simple stop.
  • the allocation in the longitudinal direction of the bag by means of a printing marker device means that there is no need for precise positioning in the longitudinal direction of the bag when the storage tape is formed.
  • the effort for aligning and depositing the ejected bags is low in that after aligning the stationary stop, the bags only a small distance, about two to three pouch thicknesses, has to be moved in the depositing direction, which means that the pouch can hardly move until it is fastened, while when forming a stack the pouch has to be moved at least the later stack thickness
  • a further advance of the method according to the invention is that the scale-like attachment of the bags to the storage tape results in different thicknesses in the bag, caused, for example, by an inlaid bottom fold or a cord hem on the bag mouth or an inserted reinforcement of a grip hole, etc., without influencing the is the number of pieces that can be stored, while, for example, a stack of bags of unequal thickness leads to an increasing deformity of the stack, which either makes it difficult to allocate them safely, forces the number of pieces to be reduced or even makes reliable stacking of the bags impossible at all.
  • the invention also relates to storage tapes produced by this method.
  • a first bag 1 is just leaving the machine, followed by bag 2 via the pair of rollers 3 belonging to the manufacturing machine at speed and direction E, in such a way that the bag mouth 4 formed from the upper side wall 5 and the protruding lower side wall 6 approximately as is the case with most known manufacturing processes.
  • This bag 1 is now aligned by means of a stop 14 in the storage tape formation direction G, is deposited by means of a depositing device 13 like the previously drawn-in bag 11 such that the region 8 of the projecting lower side wall 6 by means of a fastening device 7 at the end region of the projecting lower side wall 6 of the previously placed bag 12 can be fastened, preferably by welding, the fastening length 8 preferably being shorter than the bag width and approximately corresponds to the later pack width.
  • the bags 11 and 12 which are fastened to one another, are transported together with the storage belt 15 by a distance A in the direction G, the distance A being essentially dependent on the length of the protruding side wall and on desired distance of the bags in the storage belt 15 is determined and freely selectable, so that the bag 2 can now be ejected, aligned, stored, fastened and transported further. It is irrelevant whether the individual bags are attached approximately point-wise, linearly or approximately by stapling or gluing.
  • the perforation 10 is made approximately together with the fastening, for example by welding, and this, for example, with the fastening device moving along and with a continuously driven transport system 17, 18.
  • the storage tape 15 formed in this way can now be interrupted, if desired, placed in boxes or rolled up in bundles or otherwise handled for further transport, in which case the last end of the storage tape generated in each case in the direction of the bag opening approximately for allocation the filling machine passes on, the storage tape from the individual sections can be put together again endlessly.
  • FIG. 2 shows the method according to the invention for forming the storage belt 15 by means of carrier tape 20.
  • this bag 1 is aligned and deposited with the depositing device 13 so that it comes to lie in accordance with the drawn bag 11 and by means of fastening device 7 along the fastening line 8, which in turn is shorter than the bag width, fastened on the carrier belt 20, which is transported from a feed roller 19 via the deflecting roller 18 from the feed roller 17 in direction G, then together with the carrier belt in direction G transported further until the next following bag can just be fastened again with its projecting lower side 6 on the conveyor belt, so that in the further course a storage belt 15 is formed from individual bags fastened to one another.
  • FIG. 3a with associated section FIG. 3b shows the storage tape 15 produced by the method according to the invention according to FIG. 1, the last bag 30 deposited here having the beginning area of its projecting lower side wall 6 with the end area of the projecting side wall of the previously placed bag 31, preferably by welding along the attachment zone.
  • FIG. 4a with an associated section along AA shows the storage tape 15 correspondingly produced according to FIG. 2, the last bag and the protruding side wall 6 of the last deposited and aligned individual bag 40 being attached to the carrier tape 20, preferably along the bag mouth 39 and along the fastening zone 8, preferably by welding , wherein the carrier tape can advantageously be made narrower than the bag width.
