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 transport 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 tension the respective link chain outwards 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.
- an essentially oval filling opening can be formed, which enables the opening edges of the bags to be opened and closed uniformly without abrupt deflections.
- this device permits a high transport speed of the bags and thus a high filling speed without fear of an inadmissible material loading of the bags.
- the opening edges of the bags between the slats and the associated transport belts also run in without any major change in direction and therefore without any problems. The same applies to the leakage of the bag after it has been filled.
- the hinge 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. This is achieved in that the joints are arranged between the slats. This inevitably results in a sufficient lever arm between the respective hinge axis and the lamellae, so that when the hinge points approach each other, the lamellae reliably spread 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 the bag material is subjected to little stress even 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.
- At least the surface of the roller can be made of rubber or plastic, or it can be equipped with bristles that are closely arranged.
- the surface of the roller can also be designed to be uneven in such a way that the surface is provided with rotationally symmetrical circumferential grooves.
- the device for spreading the filling opening of a longitudinally folded film strip divided into individual bags comprises a mounting frame 1, on which two parallel to each other and for the transport direction of the film strip are arranged guide devices 2, on which by means of a z. B. pneumatically acting actuator 4, a carriage 3 is displaceable.
- 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 pulleys which are mounted on the mounting frame 1 accordingly. While the pulleys 6 z. B. driven by an electric motor 5, the pulley pairs 7 and 8 run freely. Pulleys (not shown) can also be freely rotated on the carriage 3.
- a spreading arrangement is provided, which is formed by two slats 11 arranged parallel to one another and to the transport direction of the film strip or the individual bags.
- the slats 11 come to lie between the opening edges of the respective individual bag and clamp them in cooperation with the assigned transport belts 9.
- the slats are hinged together at their two ends by means of joints 12 and 13. While the hinge 12 is arranged in a fixed position on the assembly frame 1, the hinge 13 is assigned to the slide 3 and moves with the slide 3.
- the filling opening of the respective bag is spread apart in that the slide 3 and thus the hinge 13 in Transport direction of the film strip is shifted in the direction of the joint 12, whereby the slats 11 are spread apart.
- the conveyor belts 9 make this movement due to an arrangement to be described in more detail. Due to the separation of the slats 11 and the transport belt 9, the opening edges of the bag, which are clamped between the components mentioned, are also moved apart, whereby the filling opening is formed on the bag. After filling, the filling opening of the bag is closed again by the slats 11 and together with them the transport belts 9 being moved towards one another again by the carriage 3 being moved back with the joint 13 being carried along. The filled and then closed again in the manner described is pulled off from the slats 11 by the transport belts 9 and the next bag to be filled is pushed onto the slats 11 with its opening edges.
- the transport belts 9 can follow the described movements of the slats 11, they are guided around compensation rollers 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 in turn is rotatably connected 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.
- the transport belts 9 are additionally guided in the area of the slats 11 by means of guide disks 15 which are mounted on arms 15a pivotably arranged on the mounting frame 1, which are under the action of springs 14 so that the guide rollers 15 are always pressed in the direction of the slats 11.
- a spreading member 17 is provided on both the inlet side and the outlet side. While the inlet-side expansion member 17 widens in a wedge shape, the outlet-side expansion member 17 tapers accordingly in the transport direction. To further improve trouble-free running-in of the opening edges of the bags between the slats 11 and the associated transport belts 9, it is advisable to arrange a V-shaped strip 16 made of elastic material around the respective expansion element 17. This can also run between the slats 11 and the associated conveyor belt 9.
- bags made of film material can be processed exactly, but also from other suitable materials, e.g. B. networks or the like.
- FIG. 3 there is a roller 23 above one opening edge of the filling opening 24, which is rotatably mounted on an axis 25 which is aligned essentially parallel to the conveying direction of the film material.
- 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.
- 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 partially 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 over a deflection roller 30 shortly before the roller 23.
- 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, that is. H. against the filling direction of the product.
- the conveyor belt 29 is followed by a cover plate 31, which lies closely above the roller and is adapted to the concave contour of the roller 23 with respect 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.
