Description

State of the art

The present invention relates to an arrangement for selectively packing a plurality of elements, in particular flexible bags, from above or from the side into a box, in particular into a box. Furthermore, the present invention relates to a cassette for packing a plurality of elements, in particular flexible bag, in a laterally open or sideways tilted box, in particular in a carton. Moreover, the invention relates to a method for packing a plurality of elements, in particular flexible bag, in a laterally open or sideways tilted box, in particular in a carton.

The carton packers known in the art are often designed for a very specialized application, thereby offering no flexibility for future types of packaging and applications. The previously known systems usually have no modular structure. As a result, different shunting and layering of bags in the box can be realized very difficult, or only with considerable effort. Previously known systems offer by design no way to put the bags either horizontally or vertically in the boxes. In addition, the non-modular systems do not allow format change with respect to the box or with respect to the bag. In the case of the non-modular packaging systems, such a format change is extremely complicated and involves the replacement of heavy and bulky components. In addition, the machines on the market sometimes operate over very long distances, through which the elements to be packaged have to be transported into the boxes. Thus, high travel speeds and correspondingly large drives are necessary, which do not work more energy efficient. Furthermore, the required footprint for the line integration is very large.

Disclosure of the invention

The arrangement according to the invention for selectively packing a plurality of elements from above or from the side into a box enables a simple, cost-effective and robust cardboard box packer which, thanks to its modular construction, allows a large number of shunting and layer patterns and allows its flexibility to be extended to other types of packages later. This is made possible by an arrangement for selectively packing a plurality of elements, in particular flexible bags, from above or from the side into a box, comprising: a box inlet for feeding the boxes continuously, a loading station offset to the box inlet, a box outlet for discharging the boxes A cassette for receiving all the elements of a box, and a loading device for canceling at least one element outside the loading station and for inserting the at least one element from above into the box or into the cassette. The arrangement for loading the box from above is adapted to move the open-top box by means of a first displacement device from the box inlet to the loading station and to pack the box on the loading station, and wherein the arrangement for packing the box from the side is adapted to leave the laterally open box or tilted box to the side of the box inlet, to load the cassette on the loading station and move the elements by means of a pressure plate from the cassette into the box.

The dependent claims show preferred developments of the invention.

The arrangement according to the invention makes it possible, in particular, to pack stand-up pouches, pillow bags and doy-style packings into the usual cartons and trays. A simple and fast format change is possible. Thus, for a change from the horizontal layering of the bags (packing the boxes from above) to the vertical layering of the bags (packing the boxes from the side), only the cassette must be pushed onto the loading station.

It is always possible to load the boxes with a drop height of zero. This means that the elements do not need to be dropped but can always be dropped from the top. In addition, the invention allows a very small footprint for the entire system, which has very short travels result.

The arrangement according to the invention has a structured structure and is divided into clearly defined module areas. Thus, the arrangement is divided into the box inlet, the loading station, the box outlet and the loading device. Both the loading of the boxes from above and the packing of the boxes from the side are carried out with one and the same loading device.

In an advantageous embodiment, it is provided that the pit inlet comprises a first linear transport device offset in parallel with the loading station. In addition, the loading station preferably has a second linear transport device for transporting the boxes under the loading device and / or for transporting the packed boxes to the box outlet. As a result, the boxes can be moved from the pit inlet to the parallel transport device of the loading station. On the transport device of the loading station, the boxes are moved one step further under the loading device, loaded there and then by means of the transport device of the loading station further transported. This is followed by a new shift to parallel offset box outlet.

Moreover, it is preferably provided that the loading station comprises a changer device for exchanging the cassette under the loading device and / or for exchanging different cassettes under the loading device. For a packing of the boxes from the side of the boxes remain on the linear transport route of the pit inlet. At the loading station is a cassette, which is equipped from above with the loading device. In order to allow easy replacement of the cassettes, the changer device is provided.

Furthermore, a second displacement device is preferably provided for displacing the boxes from the loading station to the box outlet. This second displacement device is necessary when the boxes are moved for loading from the top of the loading station and are equipped there directly by means of the loading device.

For the loading of the boxes from the side, either the boxes can already be arranged in the tilted, laterally open state on the pit inlet, or it is preferably provided a tilting device for tilting the boxes on the pit inlet.

Furthermore, according to the invention, a cassette for packing a plurality of elements, in particular a flexible bag, is provided in a box that is laterally open or sideways tilted. The cassette comprises two opposing side walls, a pressure plate located between the side walls and a bottom. The floor is in particular perpendicular to the pressure plate and to the side walls. The pressure plate is in particular also perpendicular to the side walls. The pressure plate is displaceable in a direction parallel to the side walls feed direction. Likewise, the bottom plate is displaceable in the direction of loading. The cassette is used to be filled from above with the elements. Opposite the pressure plate, the box to be filled is arranged. After the finished filling of the cassette, the pressure plate is moved together with the bottom plate in the box. This allows the elements to be transferred from the cassette to the box.

It is preferably provided that the pressure plate and the bottom plate are independently displaceable. This makes it possible that the pressure plate and the bottom plate are simultaneously pushed into the carton. Then the bottom plate is pulled out first and then the pressure plate. This will ensure that items are properly placed in the box.

In addition, it is preferably provided that one of the pressure plate opposite wall of the cassette comprises a plurality, in particular four, outwardly hinged wings. The wings are adapted to keep the box, in particular the flaps of a carton, open.

In a preferred embodiment, this cassette according to the invention is used in the arrangement according to the invention described above.

The invention further relates to a method for packing a plurality of elements, in particular flexible bags, into a laterally open or sideways box, comprising the steps of: loading a cassette from above with a plurality of elements, the cassette having two opposite side walls, one between the two Side walls arranged pressure plate, and a bottom plate comprises, moving the bottom plate and the pressure plate including the plurality of elements in the box, the two side walls remain fixed, retracting the bottom of the box, and retracting the pressure plate after the bottom, in particular completely, was withdrawn ,

Embodiment of the invention

The 1 to 6 show an embodiment of the inventive arrangement 1 , In the 5 and 6 In addition, a cassette according to the invention 16 . 25 explained in detail.

The 1 and 2 show the arrangement 1 during a boxing session 3 , here executed as boxes, with elements 2 from above. The order 1 includes a pit entry 4 , designed as a linear transport device, one to the box inlet 4 parallel offset loading station 5 and one to the loading station 5 parallel staggered box outlet 6 , The loading station 5 and the pit exit 6 are also designed as linear transport devices. The transport devices of the pit inlet 4 and the pit exit 6 are collinear with each other. At the pit inlet 4 there is a first displacement device 8th to move the boxes 3 from the pit inlet 4 on the loading station 5 , At the loading station 5 there is a second displacement device 9 to move the boxes 3 from the loading station 5 on the pit exit 6 ,

Furthermore, the arrangement shows 1 a product infeed 10 for feeding the elements 2 on a product feed line 11 , The product feeding line 11 is designed as a linear transport device and is parallel to the loading station 5 arranged. The product feeding line 11 transports the several elements 2 in the area of a loading device 7 , The loading device 7 includes several suction pads 14 , With these suction pads 14 picks up the loading device 7 at the same time several of the elements 2 and lifts those elements 2 from the product delivery line 11 at.

The loading station 5 transports the box to be loaded 3 under the scope of the loading device 7 , The Elements 2 be from the loading device 7 outside the loading station 5 addressed. Then the loading device lifts 7 the Elements 2 and transport it over the box 3 on the loading station 5 , At appropriate position moves the loading device 7 the Elements 2 down and set the elements 2 in the box 3 from. This process is repeated until the box 3 with the desired number of elements 2 is filled. Then the loading station transports 5 The box 3 to the second displacement device 9 , The second displacement device 9 shifts the box 3 on the pit exit 6 ,

The 3 and 4 show the arrangement 1 while packing the boxes 3 of the page. This left the boxes 3 while packing on the pit inlet 4 , In this embodiment, for this purpose, in particular an intermediate transport route 15 as part of the pit inlet 4 used. This intermediate transport route 15 extends the linear transport device of the pit inlet 4 to a seamless transition to the pit outlet 6 , Further, for this type of packaging, the first displacement device 8th at the same time as tilting device for the boxes 3 educated. Alternatively, a separate tilting device may be provided. By means of the tilting device, the boxes 3 tilted so that they are open at the side and over the horizontal loading direction 27 can be packed.

For packing the boxes 3 from the side is on the loading station 5 by means of a changer device 17 a cassette 16 substitute. The cassette 16 is then on the loading station 5 under the loading device 7 ,

Here comes the same loading device 7 as well as in the previously described packing of the boxes from above for use. However, here by means of the loading device 7 first the cassette 16 packed from above. After the complete loading of the cassette 16 become the elements 2 along the feed direction 27 from the cassette 16 in the box 3 postponed. Following this are the boxes 3 preferred on the pit exit 6 turned back again.

5 shows the cassette 16 in detail. The cassette 16 includes a horizontal bottom plate 18 , On this floor plate 18 be by means of the loading device 7 the Elements 2 filed or layered. Side of the bottom plate 18 There are two vertical side walls 20 . 21 , Between the two side walls 20 . 21 is one to the bottom plate 18 vertical pressure plate 19 arranged. The push plate 19 opposite wall comprises four hinged wings 22 , At these hinged wings 22 is during the loading process, the opening of the box 3 , Furthermore, the cassette includes 16 a first drive 23 for moving the pressure plate 19 in the direction of loading 27 and a second drive 24 for moving the bottom plate 18 also in loading direction 27 , By means of the two drives 23 . 24 can the bottom plate 18 and the push plate 19 be moved independently of each other.

As in the 3 and 4 shown is the cassette 16 by means of the loading device 7 with the elements 2 loaded. Then the wings open 22 such that the wings 22 on the insides of the flaps of the box 3 issue. At the same time, the bottom plate 18 and the push plate 19 including the elements 2 in the direction of loading 27 move into the box. After that, initially only the bottom plate 18 out of the box 3 withdrawn. Then the pusher plate 19 out of the box 3 withdrawn.

6 shows the other cassette 25 which is essentially constructed like the cassette 16 , However, the cassette can 25 differ from their sizing and thus allows the Bepackung with other elements 2 or for other boxes 3 , As in the 3 to 6 can be seen, includes the loading station 5 the changer device 17 , designed as two parallel guide rods. This changing device 17 allows a simple and fast insertion of the corresponding cassette 16 . 25 under the loading device 7 , This is a quick change between the different cassettes 16 . 25 or between the different packaging variants, namely the packing of the boxes from above and the packing of the boxes from the side, possible.

According to the 1 to 4 be the pit entry 4 and the pit exit 6 also as a vertical line 12 designated. According to the loading of the boxes 3 or the cassette 16 . 25 by means of the loading device 27 exclusively from above. As a result, the loading station 5 in combination with the loading device 7 as a horizontal line 13 designated. In the horizontal packaging, that is the packing of the boxes from above, are the bags (elements 2 ) horizontally layered in the box 3 , That is, the box 3 can stand under the loading device 7 to be brought. In addition the box runs 3 standing in the pit inlet 4 first on the vertical line 12 in the arrangement 1 , From there will be the box 3 on the horizontal line 13 deported. On this horizontal line 13 the box is running 3 under the loading device 7 , After filling the box is running 3 Continue and get back to the vertical line 12 moved on the box 3 then the arrangement 1 leave. Through the machine control, the bags (elements 2 ) to the, depending on the loading pattern, intended position in the box 3 to be brought.

In the vertical packaging, ie the packaging of the boxes from the side, the bags (elements 2 ) in the box 3 , To now the same loading device 7 to be able to use the box for loading 3 turned. This is the box 3 not necessarily completely turned horizontally, but for example only about 75 °. This will ensure that the contents of the filled box 3 can not slip. The process looks like this:

The box 3 runs standing, so with the opening up, in the pit inlet 4 on the vertical line 12 in the plant 1 one. The box remains 3 on the vertical line 12 and is rotated about the horizontal axis by means of the tilting device. In this rotated state, the box is running 3 down to the height of the loading station 5 , The loading device 7 now filled a cassette 16 . 25 after a certain shunting pattern. Is the cassette 16 . 25 filled, the complete maneuvering is done with the pusher plate 19 in the rotated box 3 postponed. The box 3 this is done with the four wings 22 (also known as mouthpiece) held open. The Elements 2 be on the bottom plate 18 lying together with the pressure plate 19 in the rotated box 3 carried. The bottom plate 18 gets out of the box first 3 pulled, then follows the pressure plate 19 , This ensures that the elements 2 in the box 3 do not fall apart. The filled box 3 will now be transported to the return station, where the box 3 is turned back into the standing position. When standing, the box leaves 3 the order 1 ,

The cassette 16 . 25 can preferably be mounted horizontally or inclined by a certain angle. The inclination has the advantage that the elements 2 , in particular bags, when loading the cassette 16 . 25 at the pressure plate 19 are supported. As a result, geometrically imprecise bags can be processed.

The cassette 16 . 25 is open in the loading process at the top. This makes it possible to use the elements 2 with the loading device 7 to load and even re-press something to better fill the cassette 16 . 25 and thus the box 3 to reach.
