EA005436B1 - Clipping apparatus - Google Patents

Abstract

The invention relates for sealing paste-like materials in tubular casing. Preferable usage - meat and milk industry, sausage casing. Can be further applied for packing in a string net and for fastening bag's necks. Technical features improved by the invention comprise increasing safety and quality of casing clipping, as well as increasing life time of the apparatus by excluding friction of plates therebetween and providing a stable and optimum gap between the plates. The inventive apparatus, as well as its prototype, comprises two co-inserting packs of plates with V-shaped cuts, one of them has an element connecting its plates with at least one cut along the packs motion direction for passing and guiding a plate of the other pack, wherein one of packs comprises a matrix for bending clips. The following features are added to the apparatus: the pack plate with the matrix has two plates disposed on the matrix side forming together with two said elements disposed on opposite sides of these plates a box-shaped structure inside which an outer plate of the other pack may pass along the elements slots. The improved clipping apparatus design provides for plates stability against pressure upon them by filled casing during the clipping operation thus excluding their deviation and friction therebetween, as well as maintaining a stable gap between the plates. At that the packs width is stable, since thin plates are used in the box-shaped structure.

Description

The invention is used to seal pasty materials in a tubular sheath. The primary field of application is the meat and dairy industry, the manufacture of sausages. It can also be used for packaging in the net and for fastening the neck of the bags.

Clippers [1] are known in the art with two packs of plates with U-shaped cutouts that move rectilinearly towards each other. In one package there is a matrix for bending metal clamps around the neck of the loafs obtained by clamping a filled sleeve shell. To prevent the cut of the shell by the plates in such devices, it is necessary to ensure a stable gap between the pinching edges of the plates. In this clipper, this is ensured by rounding off the radii at these edges. However, it does not provide the rigidity and resistance of the plates to the pressure of the compressible shell on them, the package plates without a matrix encircle the package plates with the matrix, come into contact with them and, therefore, rely on them with significant pressure from the side of the compressible shell. With intensive use of the device, this leads to the erasure of the plates against each other - as a result, the edges are sharpened, come closer to each other and cut the shell. When creating a clipper at the same time superimposing two clamps, the width of the packet of plates and the compressible region of the shell increases, which leads to additional difficulties, because it is difficult to use plates with a large thickness that were used in the prototype.

The technical problem solved by this invention is to increase the reliability and quality of the clamping of the shell, as well as increasing the life of the device by eliminating the possibility of friction of the plates against each other and ensuring a stable and optimal gap between the plates.

Like the prototype, the inventive device includes two stacked plates of plates with U-shaped cuts, one of which has an element connecting the plates of this package with at least one groove in the direction of movement of the packets for the passage and direction of the plate of the other package, in one of the packages is a matrix for bending clips.

The following features are added to the aforementioned features of the device: in the package of plates with a matrix there are two plates located on one side of the matrix and forming, together with the two above-mentioned elements located on opposite sides of these plates, a box-shaped form inside which the outer plate of another package can pass through the grooves of the elements .

The improved design of the clamping device ensures the stability of the plates against the pressure on them of the filled shell during clamping, which eliminates their deviation and friction with each other, and also guarantees a stable gap between the plates. At the same time, the width of the packages practically does not increase, since thin plates are used in the box form.

The following is a description of the device clamping with two dies, made in accordance with the claimed design.

The device is illustrated by drawings, where in FIG. 1 shows a device with open packs of plates;

in FIG. 2 - device with closed packages of plates - the shell is not shown for clarity;

in FIG. 3 - device with closed packs of plates and pinched filled shell arrows show the pressure on the plates from the side of the shell;

in FIG. 4 shows a box shape separately;

in FIG. 5 - a package with matrices from the side of the U-shaped cuts.

The clamping device for the clipper includes the first 1 and second 2 packs of plates 3 with U-shaped cutouts 4. In the first pack are two matrices 5 for bending the clamps. Near each matrix 5, on the opposite sides of the first packet 1, there are two plates 3 fastened by elements 6 having longitudinal grooves 7 in the direction of movement of the packets 1, 2 and forming box-shaped forms together with elements 6. Edges 7 of the elements 6 enter edges the outer plates 3 of the second package 2. Additionally, in FIG. 3 shows the shell 9.

The device operates as follows.

With the open position of the packages 1, 2 of the plates 3, the filled shell 9 enters the region formed by the U-shaped cutouts 4 of the plates 3, after which the packages 1 and 2 converge. Due to the box-shaped form 8, the outer plates 3 of the first packet 1 withstand pressure from the side of the compressible shell 9 and do not deviate. The outer plates 3 of the second package 2 also do not deviate, since they have a large thickness, and their edges are located in the grooves 7 of the elements 6, which also provides a gap between the plates 3 in a box-shaped form 8 and the plate 3 of the second package 2 passing between them.

The described design guarantees stable quality of clamping and ensures long-term operation of the device without wear of the parts on which it depends.
