Definitions

  • the invention initially relates to a process for the continuous production and handling up to the filling of bags, in particular automatic bags made of a thermoplastic plastic film, with at least one hanging hole being made in the area of a filling opening in the bags and holding the bags together in batches and singularly for filling and afterwards be closed
  • a feeder device for example, is a pen stacking device that moves in the horizontal direction and picks up the separated bags on stacking pens.
  • a problem with all bag making machines with a downstream collecting or stacking device is to adapt the performance of the stacking and collecting device to the continuously operating bag welding machine in such a way that cycle interruptions in the bag production or very few cycle failures occur while a finished bag is out of the bag Stacking station removed and an empty stacking device is inserted into the stacking station.
  • the stack of bags is lifted from the stacking pins of the stacking device and is placed on the legs of the bowel with the bags now lying loosely on top of one another, or the legs of the bowel are inserted into hollow-groove-like recesses in stacking pins of the stacking device and the stack of bags is removed in this way. Then the stack of bags has to go through the legs of the bow 2
  • a transfer device of the prescribed type can be seen, for example, from DE 38 34 1 1 5 C 1.
  • the invention is based on the object of proposing a method of the type mentioned at the outset which ensures easier handling in the logistical sequence between the production and filling of bags consisting of a thermoplastic plastic film web, in particular automatic bags, and ensures an improved quality of bag stacks formed from several bags .
  • a device is to be created which, in a particularly simple manner, enables the bags in the bag stack to be optimally processed for the purpose of filling them.
  • this object is achieved in that, during the manufacturing process, the stacked bags are blocked together in places near their filling opening and in that the stack of bags in a preparation position of a feed station of a filling station, preferably an automatic packing machine, preferably a feeding station, by means of holding elements cooperating with the suspension hole or holes held in place and then the blocking of the stack of bags is released, after which the individual bag in one of the preparation positions Downstream filling position of the filling station is filled and thereby released from the holding elements and finally closed by the filling movement.
  • a feed station of a filling station preferably an automatic packing machine, preferably a feeding station
  • Optimal conditions in the logistical process can be achieved in particular if two blocking sections and two hanging holes are provided in an upper flap protruding on one side in the area of the filling opening of each bag, the distance between the essentially punctiform blocking sections being greater than the distance between the receiving holes.
  • the interlocking sections are attached to the edge of the upper flap with a semi-circular shape in cross-section, the semi-circular course of the interlocking sections being limited by a perforation line introduced into the stack of bags.
  • the idea according to the invention can be realized particularly easily if the device for feeding blocked stacks of bags into a filling station, preferably an automatic packaging machine, is characterized by a bag clamping device and a blocking slug clamping device which can be moved relative thereto.
  • the bag clamping device and the blocking slug clamping device can each have an upper and lower clamping member.
  • the clamping members of the blocking slug clamping device can be designed as clamping pliers movable in an open position and clamping position. The adjusting movement of the clamping pliers of the locking block clamping device takes place essentially in the vertical direction.
  • FIG. 1 shows a side view of a bag manufacturing machine
  • FIG. 2 shows a perspective illustration of an individual bag
  • FIG. 3 shows a corresponding representation of a stack of bags consisting of several bags
  • FIG. 4 shows a top view of a filling station with a feed station in a preparation position
  • Figure 5 on an enlarged scale a part of a deblocking device.
  • a bag manufacturing machine 1 is shown schematically, which is designed and set up for the production of bags, in particular so-called automatic bags.
  • the bag making machine includes an unwind stand 2 with a winding roll 3 made of a thermoplastic film.
  • the latter can for example, be designed as a tubular film web 7.
  • the tubular film web 4 is guided within a processing stand 5, which is only indicated schematically, via drive rollers and tensioning rollers, not shown, accommodated therein.
  • the processing stand can have 5 side or bottom fold insertion devices 7.
  • a hole punching device 9 is arranged behind the processing stand 5.
  • the hole punching device 9 is followed by a cross welding separating device 11 and a transfer device 12, to which a stacking device 13 with a pin stacking device 14 is finally connected. Finally, an interlocking station 15 is arranged in the area of the pen stacking device 14. This can be followed by an unillustrated unloading station for blocked stacks of bags.
  • Such stack of bags 6 are shown in more detail in FIG. 3. As can be seen there, these consist of a predetermined number of individual bags 8, as is shown in FIG. 2.
  • the individual bag 8 has in the area of a filling opening 1 6 a one-sided protruding upper flap 1 7, in which two suspension holes 1 8 are punched, to which tear-off perforation slots 21 are assigned at a short distance in the direction of the outer edge 1 9 of the upper flap 1 7.
  • the stack of bags in the blocking station 15 in the region of the upper link 17 are provided with blocking sections 22 which extend over the entire height of the stack and hold the individual bags 8 together in the stack.
  • the interlocking sections 22 are each delimited by a perforation line 23 which extends in a semicircle to the edge 1 19 of the upper link.
  • Such blocked stacks of bags are packed in outer cartons (not shown) and then transported to the packaging companies. To get a quick one there
  • FIG. 4 shows part of a filling station 24 which has a support surface 25 on which the stack of bags 6 can be transported in the direction of arrow 26.
  • the transport initially takes place from a pre-setting position 27 of a feed station 28 into a filling position 29, in which the bags are filled with a product, for example a bread or a similarly hard-shaped object in the manner described in more detail below, or ultimately also with flexible materials 6
  • the front ends of the bags 8 are fixed in the area of the upper flap 17 by a lower clamping member 35 and an upper clamping member 36 of a bag clamping device 37.
  • a lower clamping element 38 and an upper clamping element 39 of a blocking element clamping device 41 are placed in the area of the blocking elements 34 and this blocking element clamping device 41 is moved downwards according to the arrow 42 relative to the fixed clamping device 37 for the bags, so that due to the occurring ones Shear force the interlocking slugs 34 are removed from the bag package.
  • the interlocking plugs 34 can also be removed from the bag package in that the interlocking plugs 36 are not formed by a perforation. In this case, however, the interlocking slugs must be cut in the preparation position from

Abstract

L'invention concerne un procédé et un dispositif permettant la production et la manipulation continue de sacs (8), notamment de sacs d'appareils automatiques, réalisés dans une bande de plastique thermoplastique, ces sacs étant manipulés jusqu'à leur remplissage. Pour simplifier la manipulation des sacs (8) dans le déroulement logistique entre la production et le remplissage et pour obtenir une meilleure qualité des piles de sacs (6), les sacs sont attachés (22) par places puis stockés dans la zone d'un appareil automatique d'emballage par des éléments de maintien (31) coopérant avec des trous de suspension (18). Ensuite, l'attache (22) de la pile de sacs (6) est retirée. Les sacs (8) sont alors remplis, détachés des éléments de maintien (31) par le mouvement de remplissage puis fermés. Les sacs (8) sont individualisés de façon appropriée par un appareil de détachement situé dans la zone de l'appareil automatique d'emballage.
