Definitions

• the invention relates to a device for transferring bags having a pouring spout to a rotary star, wherein a guide rail which interacts with the pouring spouts is provided for displaceably receiving the bags and has a removal end.
• the bags in question are used as packaging for pourable or flowable, ie fillable goods. They usually consist of a multilayer plastic composite material. 'For Such bags especially as a stand-up pouches used increasingly as they offer significant advantages due to their flexible outer shell during transport of the full bags and disposal of the empty bags. Depending on the use, the bags are made with or without a spout.
• bags are filled with or without a spout
• a system for transporting bags without a spout, which also includes the transfer to one or more rotating stars, is known, for example, from PCT-EP 00/04541, which also goes back to the applicant.
• a system for transporting bags which are provided with a spout is known, for example, from PCT-EP 02/10483, which also goes back to the applicant.
• the present invention has for its object to provide a device for transferring bags having a spout to a rotary star, which simplifies the transfer and at the same time ensures high clock frequencies.
• the previously derived and demonstrated object is achieved in that a slide-over device is provided which grips the bags on the spout in the region of the removal end of the guide rail, and a drive which drives the slide-over device between a removal position at the removal end of the guide rail and a transfer position on the circular path the receiving elements of the rotary star moves.
• the pusher is preferably provided with an active mechanical gripping mechanism which, in particular, forms a size-variable gap from which the spouts of the bags can be picked up.
• the gap can be designed in such a way that the spout can be gripped in an upper region, in particular in the region of the thread, and a lower region remains free for reception in the corresponding receiving element of the rotary star.
• the active mechanical gripping mechanism enables the bags to be gripped on the spout first, then moved to the transfer position on the circular path of the receiving elements of the rotary star and released there, with the mechanical gripping mechanism actively moving in order to clamp and release the spouts.
• Gripping mechanism works in a passive manner, that is, a fixed, the shape of the spout has a corresponding opening into which the spout of the bag to be transferred is pressed and held there in a force-locking manner.
• the corresponding receiving element of the rotary star would have to pull the bag out of the fixed opening of the passive gripping mechanism with force.
• the pusher can consist of an upper part with a downwardly directed end piece and a lower part which is displaceably mounted relative to the upper part, the gap for gripping the spout being formed between the downwardly directed end piece and the lower part. If the downward end piece of the upper part and the lower part are moved towards one another, the spout of a bag can be clamped between the two elements. Accordingly, the spout is released again when the two elements are moved apart.
• the lower part is advantageously mounted on a rail, which is fixed relative to the upper part, in particular is directly connected to it.
• the drive which moves the pusher back and forth, acts on the lower part of the pusher. Since the lower part is slidably mounted relative to the upper part, a spout is automatically clamped as soon as the drive moves the lower part in the direction of the downward end piece of the upper part and is moved without delay to the transfer position on the circular path of the receiving elements of the rotary star. If the drive then moves the lower part again in the opposite direction, the clamped spout becomes again Approved. If the lower part is pulled back even further, for example against a stop connected to the upper part, the same drive simultaneously moves the upper part and thus the entire pusher back into its starting position.
• the next spout can then be inserted from the guide rail into the then open gap between the downward directed end piece and the lower part.
• the main advantage of this variant is therefore that the back and forth movement of the pusher and at the same time an active gripping of the same are controlled with a single drive.
• the drive of the pusher is mechanically coupled to the drive or the central axis of the rotary star. In this way, no separate motor or control is required to drive the pusher. For example, when the speed of the rotary star changes, the speed of the pusher is automatically changed accordingly.
• the drive of the pusher is preferably designed such that a continuous rotary movement of the central axis of the rotary star is converted into a clocked to and fro movement of the pusher, in particular the lower part of the pusher.
• the drive can also be designed such that there is a pause between the forward movement of the pusher and the forward movement. This pause then leaves the corresponding receiving element of the rotary star a certain amount of time to remove the spout from the pusher or the pusher a certain amount Time to pick up a new spout from the guide rail.
• the pusher drive is advantageously designed such that the transfer device achieves 220 to 280 cycles per minute, in particular 250 cycles per minute.
• a double cam preferably driven by the drive or the central axis of the rotary star, is provided, for example, via a pinion and a chain wheel, which interacts, for example, via a linkage with a rocker, which in turn is also connected, for example, via a linkage to the pusher, particularly to the lower part of the About slide.
• the pusher is arranged transversely to the guide rail in which the bags are slidably suspended via their pourers.
• the pusher it is also conceivable to arrange the pusher at an angle to the guide rail. This only depends on how the removal end of the guide rail, the transfer position on the rotary star and the guide rail are arranged relative to one another. The shortest transfer path and thus the highest clock frequency is achieved by arranging the guide rail and the pusher at right angles to one another.
• the pusher is preferably spaced from the removal end of the guide rail by less than one pouring spout. This ensures that the bags remain securely on the guide rail and not accidentally at the removal end of the guide rail can fall down.
• a pivotable closure element can also be provided, which alternately opens and closes the guide rail in the working cycle and in this way forms an additional safety mechanism for protecting the bag from unintentionally falling out of the rail.
• a clocked linear drive which shifts the bags in the guide rail in the direction of the pusher.
• the linear drive preferably comprises an insertion finger, which presses the bags located in the guide rail in the direction of the pusher.
• the device according to the invention for transferring bags with spouts to a rotary star has an advantageous embodiment in that the rotary star is provided with a plurality of inner carousels.

• Fig. 3 is an enlarged side detailed view of a spout gripped by the pusher.
• FIG. 1 of a device according to the invention for transferring bags 1 with spouts 2 to a rotary star 3 has a guide rail 4 which interacts with the spouts 2 for displaceably receiving the bags 1 in the indicated direction of advance.
• a clocked linear drive 5 is provided which includes an insertion finger 6, the insertion finger 6 applying pressure to a large number of bags 1 located in the guide rail 4 in the direction of advance, that is to say in the direction of the pusher 7.
• the pusher 7, after having gripped a bag 1, is driven by a drive 9 from a removal position 10 at the removal end 8 of the guide rail 4 moved to a transfer position 11 on the circular path of the receiving elements 12 of the rotary star 3.
• the rotary star 3 is one which has twelve inner carousels 13 at the same distance on its outer circumference, each of these inner carousels 13, which itself rotate, having four recording elements 12.
• Each of these receiving elements 12 takes over a bag 1 on the spout 2 from the pusher 7.
• the pusher 7 is at the moment when a receiving element 12 of the rotary star 3 detects a spout 2.
• the side view shown in Fig. 2 shows the slide 7 and its drive 9.
• the slide 7 consists of an upper part 14 and a lower part 15 which is mounted displaceably relative to the upper part 14. Between a downward end piece 16 of the upper part 14 and the lower part 15, a gap 17 is formed, in which the spout 2 of a bag 1 is located at the moment shown.
