Device for manufacturing packages

The invention relates to a device for producing packaging of disk-shaped, cut food or the like.

In the document FR-A 2,691,440 a packaging for food is described, wherein the product to be packaged, which for example consists of slices of ham, is formed into coils, which are arranged side by side in the package. The packaging consists of a beaker-shaped bottom part which is closed by a film. The mentioned document does not describe how the winding may be formed by mechanical means. If the winding formed by hand, resulting in a considerable amount of work.

In the document US-A 5,012,726 an apparatus is described, said dough disks are formed into a roll. The dough is thereby transported on a conveyor belt and passed to a rotating winding device by a soft-like sheet piece with its front end. This winding apparatus comprises a winding mandrel, which is formed by two parallel aligned to the axis of rods. In this way the dough disks can be wound up and subsequently be subjected to further processing, for example, a baking process is supplied.

The document US-A 4,470,792 describes another winding device for the production of sponge rollers. By means of a baffle, the zoom out on a conveyor belt dough portions of a winding device supplied, which is formed by cylindrical pins. By means of a belt arrangement, the dough portions are guided around the winding mandrel several times to form single winding.

The invention is based on the object to provide a device for producing packages of disc-shaped, cut foods or the like, with which it is possible, for example, ham slices completely wrap to mold, so that from these winding a package can be formed.

The object is achieved by the device according to claim. 1

If only two rods used, as is known per se, arises in view of the consistency of the material to be cut to be processed no sufficient zylinderische shape of the coil. Rather, the height of the wound material to be cut is then substantially smaller than the width dimension.

In a further embodiment of the invention provides that the winding mandrel provided for conveying in the discs conveyor by the losing end of the conveyor and the bars having the disks supporting slide. It has been found that generally a small gap between the emitting end of the conveyor and the bars is inevitable, since space for the formation of the package must be left. For thin slices, there is now a risk that these adhere to the conveyor and do not enter between the rods. This prevents the above-mentioned slide.

The slideway can be formed in various ways. In a preferred embodiment of the invention, the slideway consists of rods and the conveyor is made up of circulating belts, straps or the like, wherein the rods between the belts, straps or the like are arranged. The slide can, for example, be configured to advance and retreat in the conveying direction, so that the slide may be substantially effective in the interstices between the rods only at the moment of insertion of the discs. If the slide is retracted, the winding can be formed. Also, the arrangement of a resilient slideway is possible, which is then pushed away in each case during the winding operation of the rods. The slide may, in particular rest on the bars, so that it is ensured that even thin slices reach the desired location between the rods.

In a further feature of the invention, the package is arranged below the winding device and the winding device, the winding sets in the package may fall off or the winding in the package or in the provided there wells.

It is noted that FIGS. 3, 4 and 5 show the formation of a winding mandrel, which is characterized by the inventive design of the mandrel, as applicable in the claim 1, is different.

The device shown in FIG. 1 consists essentially of the cutting machine 10, the conveyer 11, the winding device 1, a further conveyor 12 and packaging machine 3.

The cutting machine 10 cuts of a material to be cut from 14 individual slices 15, which fall on the conveyor 11th This conveyor is in the embodiment shown as a conveyor belt dargestellt.Es but can also be another conveyor, for example, a transport plate or similar device, be provided.

Behind the winding device 1, which will be described in greater detail below, enter the locally manufactured winding 16 on the conveyor 12 which preferably has recesses 17 which are adapted to the size of each winding 16th

The conveyor 12 is also shown in the embodiment shown as a conveyor belt. Again, other funds are used, if desired.

The winding 16 in the troughs 17 are conveyed to the packaging machine 3 and there packaged in a conventional manner. The insertion of the winding 16 in the packaging machine can be automatically performed, but it is also possible to supply the winding by hand, the packaging machine.

The packaging machine 3 produces, as known per se, packaging 13, namely a shell 18 which is closed by a sealed-lid 19th The dish takes adjacent the winding 16. It is also possible to mold in the shell 18 trough-like depressions. 4

FIGS. 3, 4 and 5 illustrate a winding device 2, in which the individual windings are each wound on a winding mandrel 20. On the rotator 21 six mandrels 20 are mounted rotatably on each. The direction of rotation of the mandrels 20 is indicated by the arrow 22, the direction of rotation of the rotary means by the arrow 23. In order to achieve the rotation of the mandrels 20 about the axis 35, carrying the pins 20, for example, a gear wheel 29, which rolls on the stationary ring gear 30 , The mandrel 20 can, if desired, also be driven in the reverse direction. Each mandrel is provided with a bracket 24, as is apparent from FIG. 5. In the gap between the bracket 24 and the mandrel 20, the front end of the disk 15 is inserted, which is conveyed forward on the conveyor eleventh The mandrel 20 is also surrounded by a part-cylindrical shell 25, which facilitates the winding operation.

The orientation of the feeding-in direction of the discs 15 to the pins 20 and the alignment of the mandrels 20 to the carrier 21 may also be angled to achieve helical winding sixteenth

If the respective winding mandrel reaches a position, which is marked by the reference numeral 26, the stripping device 27 in function (cf. Fig. 4.) Occurs, which strips the molded winding from the mandrel 20, so that it in one of the wells 17 of the conveyor 12 arrives. The revolving roller 28 of the conveyor 12 is disposed coaxially with the rotator 21st

The device shown in FIG. 6 consists essentially of the conveyor 11 and the winding device 1. The conveyor 11 comprises an endless conveyor which consists of the two roller assemblies 44, 45 which serve to guide cords or ribbons. 8 It can be 44 driven via the shaft 46, for example, the rear roller assembly. The frame of the conveyor is designated by 47th In the frame 47 a number of rods 48 is further mounted, whose rear ends are connected by a cross member 49 with each other. At the Traverse sits 49 a bracket 50 which is engaged by a not shown drive. This drive can impose a movement according to the double arrow 51 the rods.

The front ends of the rods 48 together form a slide 9. When the slide is pushed 9 forward protrude the ends of the rods in the spaces between the rods 32 of the winding apparatus into it, as is apparent in particular from the illustration of Fig. 7. In this way it is prevented that the discs 15, which are conveyed forward by the belts 8 to fall into the gap 42nd reach the discs 15 in this manner secure the space between the bars 32. The conveying in of the discs 15 should be effected as far as, that the rods 32 detect during the winding operation the disc beginning safe and form the winding.

As is apparent in particular from FIG. 6, the ends 33 of the rods 32 are held by a carrier 34 which is in turn connected to the shaft 5.

To form a roll is carried out as follows. In one position of the device, as 6 and 7 can be seen for example from the FIG., A plate 15 is conveyed forward so that it reaches with its front end between the rods 32. Now, the slide 9, consisting of the front ends of the rods 48, is retracted. The shaft 5 carries out several turns, so that from the disc, a winding is formed. The hold-6, which is supported by a frame part 7 and is slightly resilient construction, presses against the outer periphery of the package and ensures that a compact winding possible is obtained.

The direction of rotation of the shaft 5 can rotate clockwise or counterclockwise while. Is the wrapping done formed, the shaft 5 is retracted to the rods 32 in the direction of arrow 36, ie, the bars 32 are removed from the inside of the reel. For this movement, it is advantageous if a scraper 27 is provided, which excludes the entrainment of the roll. It is noted that this stripper 27 is shown only in the diagram of FIG. 7 and 8. The scraper 27 can be for example a ring which is axially fixed. In cross-like design, the wiper will rotate with the rods.

Are the bars 32 withdrawn, 16 drops of the winding formed in one of the wells 41 of the tray 18th

In FIG. 8 is a modification of the invention is shown. There are the rods 48 forming the slide is replaced by a slideway 9 that are formed from a resilient rod or from a plurality of such resilient rods. These rods are supported by the Traverse 31st In the formation of the mold according to Fig. 8 it is not necessary to retract the slide. Both in one as in the other direction is the slide which is resting with their front ends on one of the rods 32, dodge.
