Definitions

  • the invention relates to a device for spreading the filling openings of bags of film material or the like connected to one another in a band-like manner, consisting of two transport belts, between which the bags are guided with their opening edges and which are each guided by at least one compensation roller that can be moved in the bag transport direction, and consisting of a between the opening edges engaging spreading arrangement, which comprises two flexible elements, each fixed at one end and movably mounted at the other end, which, together with the associated conveyor belts, grasp the opening edges of the respective bag and can be moved outwards by means of adjusting means.
  • the flexible expansion elements consist of link chains which are stretched outwards to form the filling opening on the respective bag.
  • the actuating means which excite the respective link chain consists of a bracket provided with a pull rod which engages the chain approximately in the middle of the filling opening and pulls it outwards perpendicularly to the transport direction of the band-like bags.
  • the flexible elements are formed by two essentially parallel elastic lamellae, which are connected at their ends by joints lying between the lamellae, of which one joint is stationary and the other joint is arranged on a carriage movable in the direction of the first joint, and that the compensation rollers are located on a carrier which can be moved together with the carriage and which is connected to the carriage by means of a differential gear.
  • the articulated axes are arranged with respect to the lamellae in such a way that a sufficient lever arm is ensured which inevitably leads to the lamellae spreading apart.
  • any preselectable tensioning force between the conveyor belts and the spreading lamellae can be set independently of the opening width.
  • the frictional force exerted on the opening edges of the bags can be kept at a desired low value when passing through the opening edges between the conveyor belts and the spreading lamellae, so that there is little stress on the bag material even at high transport speeds. This also leads to high operational reliability of the device according to the invention at high transport speeds.
  • This device is also characterized by a simple structure and great operational reliability.
  • the opening and closing movement of the slats can be achieved with extremely simple components.
  • the control of these components poses no problems.
  • the object of the invention is to develop the above-mentioned device in such a way that clogging of the filling opening is avoided with certainty.
  • a rotating part in particular as a roller, is arranged, which is rotatably mounted on an axis aligned essentially parallel to the conveying device of the filling material and is driven counter to the filling direction of the filling material.
  • this role is assigned to a filling shaft with a rigid filling opening.
  • the counter-driven roller ensures that the jam is loosened and the blockage is released so that a continuous filling process is ensured.
  • the roll on the filling material has a concave, rotationally symmetrical lateral surface, the contour of which is adapted to that of the filling opening and the filling shaft connected thereafter.
  • the contour of the roller can be aligned with the substantially vertical wall of the filling shaft located above the respective opening edge or, if necessary, protrude a little into the filling shaft.
  • a cover plate is arranged between the roller and the conveyor belt, which is attached on the one hand to the filling shaft and on the other hand partially overlaps the contour of the roller.
  • the device for spreading the filling openings of a longitudinally folded film strip divided into individual bags comprises a mounting frame 1 on which two guide devices 2 are arranged parallel to each other and to the transport direction of the film strip, on which a slide 3 can be displaced by means of, for example, a pneumatically acting actuating device 4.
  • the film strip is transported by means of two parallel conveyor belts 9 which capture and guide the opening edges of the film strip.
  • the transport belts 9 are driven or guided by means of correspondingly arranged ones Pulleys which are mounted on the mounting frame 1 accordingly. While the pulleys 6 are driven, for example by means of an electric motor 5, the pairs of pulleys 7 and 8 run freely. Pulleys (not shown) can also be freely rotated on the carriage 3.
  • the conveyor belts 9 can follow the described movements of the slats 11, they are guided around compensation disks 10, which are mounted on a carrier 18 which can be displaced along the guide rods 2.
  • the synchronization of the movement of the displaceable carrier 18 with respect to the movement of the carriage 3 takes place by means of a lever 19 which is rotatably connected on the one hand to the mounting frame 1 and on the other hand interacts with the carriage 3 by means of two coupling rods 20 and 21.
  • the coupling rod 20 is articulated on a carrier of the slide 3 and the lever 19, the coupling rod 21 on the lever 19 and the carrier 18.
  • the points of engagement of the coupling rods 20 and 21 on the lever 19 are selected such that the transport belts are kept taut during the opening and closing movement of the plates 11.
  • bags made of foil material can be processed precisely, but also from other suitable materials, e.g. Nets or the like.
  • the lateral surface of the rotationally symmetrical body has a concave generatrix 26, which is preferably adapted to the contour of the opening edge.
  • the generating line 26 is preferably aligned with the one opening edge of the extremely spread filling opening 24. However, the generating line 26 can also protrude a little into the filling opening.
  • FIGS. 1 and 2 the device shown in FIGS. 1 and 2, insofar as it relates to the filling area, is arranged under a filling shaft 27, the cross-sectional area of which is essentially adapted to the cross-section of the filling opening 24.
  • the roller 23 is shown in cross section, it being assumed that the roller is mounted with its axis in the walls of the filling shaft.
  • the roller 23 is part hidden behind the wall 28 of the filling shaft, which has the contour of an opening edge of the filling opening.
  • a conveyor belt 29 is located diagonally above the roller 23 and runs shortly before the roller 23 via a deflection roller 30.
  • the conveyor run of the conveyor belt 29 moves in the direction of the filling shaft and conveys the material to be filled in.
  • the roller 23 moves according to the arrow C in the opposite direction to this, ie against the filling direction of the filling material.
  • a cover plate 31 adjoins the conveyor belt 29, which lies closely above the roller and is adapted to the concave contour of the roller 23 with regard to its lower edge. This means that only the upper sector a of the roller 23 is exposed and can act on the filling material.
  • filling material If filling material is brought in by means of the conveyor belt 29, it falls onto the cover plate 31 and from there via the sector a of the roller 23 into the filling shaft 27 and from there through the filling opening into the bag 22.
