Arrangement for packing boxes 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. This can be different

Shunting and layering of bags in the carton are very difficult, or only with considerable effort, realized. 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. This means that high traversing speeds and correspondingly large drives are necessary, which are no longer necessary energy efficient work. 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 allows a multitude of maneuvering and layer patterns due to its modular structure and its flexibility allows it to be extended to other types of packaging later.

This is made possible by an arrangement for selectively packing a plurality of elements, in particular a flexible bag, from above or from the side into a box, comprising: a box inlet for continuously feeding the boxes, a loading station offset to the box inlet, a box outlet for

Removing the boxes, a cassette for receiving all the elements of a box, and a loading device for lifting 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 a

Packing the box from above is adapted to move the open-topped 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 formed, the to leave the box open at the side or the box tilted sideways on the box inlet, to load the cassette on the loading station and to move the elements out of the cassette into the box by means of a push plate.

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 ones

Boxes and trays. A simple and fast format change is possible. So, for a change from the horizontal layering of the bags (packing the boxes from the top) to the vertical layering of the bags

(Packing the boxes from the side) only the cassette are 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 boxing of the boxes from above and the boxing of the boxes

Embodiment of the Invention FIGS. 1 to 6 show an embodiment of the invention

Arrangement 1. In Figures 5 and 6 is beyond a

Cassette 16, 25 according to the invention explained in detail.

Figures 1 and 2 show the arrangement 1 during a package of boxes 3, here executed as boxes, with elements 2 from above. The order

1 comprises a box inlet 4, designed as a linear transport device, a loading station 5 offset parallel to the box inlet 4 and a box outlet 6 offset in parallel with the loading station 5. The loading station 5 and the box outlet 6 are likewise designed as linear transport devices. The transport devices of the box inlet 4 and the box outlet 6 are collinear with one another. At the pit inlet 4 is a first

Transfer device 8 for moving the boxes 3 from the box inlet 4 to the loading station 5. At the loading station 5 is a second

Displacement device 9 for moving the boxes 3 from the loading station 5 to the box outlet 6.

Furthermore, the arrangement 1 shows a product inlet 10 for feeding the elements 2 onto a product feed line 1. The product feed line 11 is designed as a linear transport device and is arranged parallel to the loading station 5. The product feed line 1 1 transports the several elements 2 into the region of a loading device 7. The loading device 7 comprises a plurality of suction grippers 14. With these suction grippers 14, the loading device 7 simultaneously grips a plurality of the elements 2 and lifts these elements 2 from the

Product feed line 1 1 on. The loading station 5 transports the box 3 to be loaded under the

Area of action of the loading device 7. The elements 2 are picked up by the loading device 7 outside the loading station 5. Then the loading device 7 raises the elements 2 and transports them via the box 3 on the loading station 5. The corresponding position moves the

Loading device 7, the elements 2 down and sets the elements 2 in the box 3 from. This process is repeated until the box 3 is filled with the desired number of elements 2. The loading station 5 then transports the box 3 as far as the second transfer device 9. The second transfer device 9 moves the box 3 onto the box outlet 6.

Figures 3 and 4 show the arrangement 1 during the loading of the boxes 3 from the side. In the process, the boxes 3 remain on the pit inlet 4 during packing. In this embodiment, in particular an intermediate transport path 15 is used as part of the pit inlet 4. This intermediate transport path 15 extends the linear transport device of the box inlet 4 to a seamless transition to the box outlet 6. Furthermore, the first displacement device 8 is simultaneously designed as a tilting device for the boxes 3 for this type of packing. Alternatively, a separate tilting device may be provided. By means of the tilting device, the boxes 3 are tilted such that they are laterally open and can be packed over the horizontal loading direction 27.

For loading the boxes 3 from the side, a cassette 16 is loaded onto the loading station 5 by means of a changer device 17. The cassette 16 is then located on the loading station 5 below the loading device 7.

Here comes the same loading device 7 as well as in the previously described Bepackung the boxes from above used. However, the cassette 16 is initially packed by means of the loading device 7 from above. After the cassette 16 has been completely packed, the elements 2 are moved along the direction of loading 27 from the cassette 16 into the box 3. Following this, the boxes 3 are preferably turned back on the pit outlet 6 again. FIG. 5 shows the cassette 16 in detail. The cassette 16 comprises a horizontal base plate 18. The elements 2 are deposited or layered on this base plate 18 by means of the loading device 7. Laterally of the bottom plate 18 are two vertical side walls 20, 21. Between the two side walls 20, 21 a to the bottom plate 18 vertical pressure plate 19 is arranged. The the

Pressure plate 19 opposite wall comprises four hinged wings 22. These hinged wings 22 is during the loading process, the opening of the box 3. Furthermore, the cassette 16 includes a first drive 23 for moving the pressure plate 19 in the feed direction 27 and a second drive 24th to move the bottom plate 18 also in

Loading direction 27. By means of the two drives 23, 24, the

Base plate 18 and the pressure plate 19 are moved independently. As shown in Figs. 3 and 4, the cassette 16 is replaced by means of

Loading device 7 loaded with the elements 2. Then, the wings 22 open so that the wings 22 abut the inner sides of the flaps of the box 3. Then, at the same time, the bottom plate 18 and the pressure plate 19 together with the elements 2 in the loading direction 27 are moved into the box. Following this, initially only the bottom plate 18 out of the box

3 retired. Then, the push plate 19 from the box 3rd

withdrawn.

FIG. 6 shows the further cassette 25, which is essentially constructed like the cassette 16. However, the cassette 25 can deviate from its dimensioning and thus allows the packaging with other elements 2 or for other boxes 3. As in FIGS. 3 to 6 see, that includes

Loading station 5, the changer device 17, designed as two parallel guide rods. This changing device 17 allows a simple and quick 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

Bepackungsvarianten, namely the packing of the boxes from above and the packing of the boxes from the side, possible. According to FIGS. 1 to 4, the box inlet 4 and the box outlet 6 are also referred to as the vertical line 12. According to the invention, the loading of the boxes 3 and the cassette 16, 25 by means of the loading device 27 takes place exclusively from above. As a result, the loading station 5 in combination with the loading device 7 is referred to as a horizontal line 13. In the case of the horizontal packaging, ie the loading of the boxes from above, the bags (elements 2) lie horizontally layered in the box 3. That is, the box 3 can be placed standing under the loading device 7. For this purpose, the box 3 runs standing in the pit inlet 4 first on the vertical line 12 in the arrangement 1. From there, the box 3 is pushed onto the horizontal line 13. On this horizontal line 13, the box 3 passes under the loading device 7. After filling the box 3 continues to run and is moved back to the vertical line 12, on which the box 3 then leave the assembly 1. About the machine control, the bags (elements 2) to, depending on

Loading pattern, provided position in the box 3 are brought.

With the vertical packing, thus the packing of the boxes from the side, the bags (elements 2) stand in the box 3. To the same now

To be able to use loading device 7, the box 3 is rotated for loading. The box 3 is not necessarily turned completely horizontally, but for example only by about 75 °. This ensures that the contents of the filled box 3 can not slip. The process looks like this:

The box 3 runs upright, so with the opening up, in the pit inlet 4 on the vertical line 12 in the system 1 a. The box 3 remains on the vertical line 12 and is rotated by the tilting device about the horizontal axis. In this rotated state, the box 3 runs up to the height of the loading station 5. The loading device 7 now fills a cassette 16, 25 for a particular Rangiermuster. If the cassette 16, 25 filled, the complete maneuvering with the pressure plate 19 is moved into the rotated box 3.

The box 3 is this held open with the four wings 22 (also known as mouthpiece). The elements 2 are supported on the bottom plate 18 together with the pressure plate 19 in the rotated box 3. The

Bottom plate 18 is first pulled out of the box 3, then follows the pusher plate 19. This ensures that the elements 2 in the box 3 do not fall apart. The filled box 3 is now transported further to the reversing station, where the box 3 is turned back to the standing position. When standing, the box 3 leaves the arrangement 1.

The cassette 16, 25 may preferably be mounted horizontally or inclined at a certain angle. The inclination has the advantage that the elements 2, in particular bags, are supported on the pusher plate 19 when the cassette 16, 25 is loaded. As a result, geometrically imprecise bags can be processed. The cassette 16, 25 is open in the loading process above. This makes it possible for the

To load elements 2 with the loading device 7 and even something

nachzupressen to achieve a better degree of filling of the cassette 16, 25 and thus the box 3.
