Definitions
- the present invention relates to a device for separating and opening a sack stacked on a sack stack, with a first carrying device rotating over deflecting rollers, preferably with two chains or toothed belts rotating in parallel and at a distance from one another, the cross bars forming sections with one another by means of at least one contact surface are connected, the uppermost sack in each case of a sack stack being raised by means of a suction device and being driven underneath by the first carrying device and being transported further, according to the preamble of claim 1.
- a disadvantage of these known devices is the fact that only a limited throughput is possible, since these chain conveyors can only be operated at low speed, since the sacks to be conveyed only rest on the chain conveyor and therefore there is a risk, particularly in the case of light sacks, that they are caused by the air stream falls off the chain conveyor.
- the space required for such solutions is high, since the chain conveyor only allows the sack to be detached from the sack stack, but then only conveys it to a subsequent transfer station without further positioning.
- the aim of the present invention is therefore a device of the type mentioned, which prevents the disadvantages described above, is simple in construction, allows an increase in the throughput of the sacks to be separated, and conveys the separated sack to a filling position after removal from the sack stack to block the separation process.
- the present invention aims to implement the separation, turning, positioning and opening of a sack regardless of the type of sack (upholstery sack, gusseted sack, etc.), the type of sack material (film, fabric or paper) and the sack format in the smallest possible space.
- the bag By clamping the bag between two carrying devices, the bag can be transported and deflected very quickly without the risk of the bag falling off the carrying device. At the same time, the deflection allows the sack to be transported from the first carrying device to the second carrying device and thus in the most confined space the sack is transferred and positioned for filling.
- the bag to be transported can be transported further by means of the second carrying device, whereas the first carrying device is in turn moved to the receiving position of the next bag to be separated.
- claims 4 and 5 enable the sack to be filled to be transferred to a sack spreading device without mechanically complicated transfer devices.
- Fig.l is a schematic view of a device according to the invention at the start of the separation process
- FIG. 3 shows a schematic view of a device according to the invention during the lifting of an uppermost sack
- FIG. 4 shows a schematic view of a device according to the invention when the bag is deflected and clamped
- FIG. 5 shows a schematic view of a device according to the invention after the bag has been deflected
- FIG. 6 shows a schematic view of a device according to the invention during the further transport of the sack
- FIG. 7 shows a schematic view of a device according to the invention during the positioning of the sack
- FIG. 8 shows a schematic view of a device according to the invention during the opening of the sack
- a stock of sacks is stored in a stack 2.
- This transport device consists of circumferential traction elements 9 (e.g. chains, toothed belts or the like) which are connected to one another in accordance with FIG. 2 by cross bars 10 which exceed the bag width.
- circumferential traction elements 9 e.g. chains, toothed belts or the like
- elastic supporting elements for example in the form of flat ovals, are slid onto these transversely arranged connecting rods 10. Similar to a checkerboard pattern, these oval support elements are alternately connected to two transverse bars 10 and thus form a braid-like open, but nevertheless coherent and thus continuous support surface.
- the lifting device 5 equipped with a plurality of suction pads 4 together with the bag 3 lifted from the bag stack 2 has reached its upper end position, the circulating transport device 8 is moved such that it is between the raised bag 3 and the bag stack 2 is pushed.
- the raised sack 3 with the area that was previously placed on the sack stack 2 now comes to the rotating transport device 8 lie and is thereby separated from the stack of bags 2 and thus isolated.
- the suction grippers 4 are now depressurized, as a result of which the sack 3 is released and now comes to lie completely on the rotating support elements 11.
- the suction cups can be subjected to a brief counter pressure pulse.
- the circumferential support device 8 consisting of the traction elements 9, the cross bars 10 and the connecting oval 11 is driven over the driven deflection roller (deflection drum) 13a, which has special flanges 25 on the sides, which ensure the synchronous driving of the traction elements 9 ensure driven and thus the bag 3 is drawn into a wedge gap.
- this wedge gap is formed on the one hand from the rotating first support device 8 and on the other hand also from the second support device 14 also running over the deflection roller 13a.
- the sack 3 is now received uniformly between the elastic support elements 11 of the first support device 8 and the second support device 14 and deflected via the deflection drum 13a. Due to the open surface structure of the carrying device 8 and the elasticity of the carrying elements 11, bags of different thicknesses can be picked up and transported without conversion measures.
- the sack held in this way between elastic support elements 11 of the first support device and the second support device 14 is guided over the deflection drum 13a and is now first picked up by the second support device 14 in accordance with FIG. 5 with the bag opening ahead and subsequently transferred continuously to a third support device 15 ,
- the first carrying device 8 continues to run synchronously with the deflecting roller 13a and the second carrying device 14 and thereby ultimately releases the bag 3 completely.
- constricting and tensioning rollers 16a, b, c form the turning station for the second carrying device 14.
- the sequence control of this positioning movement is carried out by checking the bag position by means of sensor 20, thereby ensuring an exact feeding of the bag 3 is possible in the transfer position on the support table 19 by controlling the support device - geared motor 17.
- Suction pads 22 are lowered onto the sack 3, which is positioned on the support table 19 in accordance with FIG. 7, via an angle lever kinematics 21.
- the sack 3 is now opened according to FIG
- the bag 3 can be taken over by means of a suitable swivel gripper 23.
- the opening movement of the sack 3 is supported by the rigid suction grippers 24 arranged in the front part of the storage table.
- the opened sack 3, taken over by the swivel gripper 23, can now be pushed directly onto a filling nozzle in the filling station.
- the particular advantage of using a separately driven take-over conveyor in the form of a third carrying device 15 results from the fact that the necessary position for opening and putting on the bag 3 can be approached in a controlled manner regardless of the frictional relationships between the bag material and the support table. This takes place on the one hand through the separate drive of the third carrying device and on the other hand through the use of corresponding sensor elements 20, which are suitable for detecting the sack position on the support table 19. In this way it is possible to reliably sacks of various designs and material quality in the for . To bring open position required and thus higher throughputs • the bag - filling machine to achieve.
- Another significant advantage of the present invention is based on the fact that the circumferential first carrying device is not guided around the sack magazine 1 as is customary in other methods, but can be arranged as an independent unit above the sack magazine 1. This makes it possible to implement a solution that is independent of the magazine height and that also requires a significantly smaller installation space.
- the carrying device is no longer guided around the sack magazine has the decisive advantage that it provides magazine solutions are realizable, which enable continuous system operation by swiveling out and / or pulling out the magazine below the singling station.
- magazine solutions are realizable, which enable continuous system operation by swiveling out and / or pulling out the magazine below the singling station.
- the entire installation space below the singling station is open on all four sides, and thus the magazines can be supplied or removed via these open sides.
