Description

Machine for the automatic tying of meat-filled intestines using a String or the like.

The invention relates to a machine for automatically tying meat-filled intestines, e.g. sausages or the like., By means of a string or similar fastening means.

At present, meat-filled intestines, e.g. sausages or the like, are closed by means of a string with the formation of knots only possible by tying by hand. One is content with a mechanical or machine closure with a clasp without a knot. However, such a procedure has disadvantages insofar as when the sausages are deposited etc. the volume of the contents decreases and the closure can loosen, which over time leads to a Impairment of the quality of the contents of the intestine leads.

The invention is now based on the object of proposing a machine that uses fully automatic binding of a twine with knot formation, with the performance increased considerably compared to tying by hand shall be.

To solve this problem is according to the invention a Proposed machine of the type mentioned, which is characterized by an opening through which the Meat-filled intestine passes through, a device that moves the intestine along the route where the severance payment is provided "or the bindings are provided, compresses and the meat filled into the intestine from this section pushes out, through a spindle or bobbin on which the string is wound, through elements that the Guide the coil around a section of the compressed intestine while keeping the string in a closed position Arrange a polygon or a closed curved line in such a way that the coil forms knots at the end of its movement can pass through, as well as through a device for tightening the twine after the knot has been formed by rotation the coil on its own axis.

A machine according to the invention allows fully automatic Tying off intestines that are filled with meat by means of a string to form knots so that the Advantages of the known closure by hand result, but faster work is possible. After the closure the string is led out along the intestine at the appropriate places.

Further features, details and advantages of the invention emerge from the following description of a preferred one Embodiment based on the drawing and from the further claims. Show it:

As can be seen from the drawing is1 ^, the machine an opening 10 (Figures 1, 2 and 3) through which the meat-filled intestine passes through it. Two interlocking

609842/0217

Jaws 6, 6 '(Figures 2 and 5) serve to hold the intestine in the piece xy (Figure 7)> in. which the extension (s) 21 should take place (s), to squeeze, so that from this piece of intestine xy the meat is removed and it is prepared for binding will. Each of the jaws 6, 6 'consists of a certain number of removable plates, the number is chosen depending on the length of the piece xy (Figure 7) of the intestine to be compressed.

The machine further comprises a bobbin 1 carrying the string and guide elements for the same, which are formed by a housing 11 which has two parallel, annular walls which are provided with a radial incision at point 15 (FIG. 3). The guide members also comprise two forks 3 and 3 ¹ (Figures 3 and 4), which rotate in opposite directions and can thus approach one another or spread apart, moving through the incision 13 to a piece of string that goes from the intestine to the coil 1 runs to give a polygonal, in particular triangular course (see FIGS. 8, 9), which is absolutely necessary for the formation of a node. There are also organs 4 and V provided, which cause a rotation of the bobbin 1 about its own axis in order to pull the string taut. With the help of elements 2, 12, the coil 1 is moved upwards inside the housing 11, whereupon it falls down again under its own weight, so that it is again in the starting position. During this movement, the bobbin 1 passes through the triangle of string in order to completely form the knot.

The machine according to the invention works as follows: First, the through the opening 10 (Figures 1, 2, 3, 4) passing through intestines by means of the interlocking,

6098A2 / 0217

V-shaped jaws 6, 6 '(Figures 1 and 5) pressed together. A pneumatic piston 8 is used for this purpose (FIGS. 1 and 2).

The bobbin 1 with the wound-up string coming from the intestinal piece xy (FIG. 7) is then set in rotation about its own axis, as a result of which the string 18 (FIG. 3) is pulled taut. This rotational movement is effected by two conical punch 4- ^1, 4 "(Figures 1 and 2) which in turn are driven by means of a friction mechanism 4 and shifted axially by means of the moving piston 9 through the lever system 24th

As soon as the stamps 4 ¹ , 4 ″ are switched off again, ie lifted off the spool and returned to their starting position, the two forks 3, 3 ^{1 come} into action, which rotate against each other, which is caused by two interlocking gears 15. When stepping out of the forks 3> 3 ¹ from the radial incision 13 of the guide housing 11, these place the piece of string 18 as shown in FIG.

Now the coil 1 is lifted up inside the guide housing 11 by means of the elements 2 and 12, with a Circular arc-shaped path HKL (Figure 3) passes through, whereupon it is released and by its own weight along the Arc path LMN falls down to return to the starting position H.

During this movement, the coil passes through the dashed lines in Figure 9 indicated web, they (are when the forks 3> _t 3 'is replaced or bogenlinienformige route by another device) by the polygon 3, 10, 3 ¹ passes, whereby the The node is formed. This is then tightened in that the spool 1 is set ^{in rotation about its own axis by means of the device from parts 4, 4 1} , 4 ″ and 9 (FIG. 2) in the manner described above.

- D -

After the intestine has been tied once on the right and once on the left (double knot as indicated in FIG. 7), the piston. Cylinder units 5 actuated intestinal support tongues 5 ¹ (Figure 4) in action. The two pieces of string 18 'and 18 "(FIG. 7) coming from the knot must of course lie against the intestine.

It is possible to replace the two forks 3, 3 ¹ (Figure 8), which create the polygonal (triangular) thread course, with a mechanism ζμ fulfilling the same purpose, e.g. by a lever rotatably mounted at one end, which at the other end with an eyelet is provided through which the twine runs, this lever causing the twine to run in the shape of an arc instead of a polygon.

Furthermore, the pneumatic units 4, 8, 14 etc. can be replaced by hydraulic or mechanical elements and it may determine the shape and arrangement of the devices described above, as well as the mechanism by which they are confirmed deviate from the ones presented here within the scope of the claims.
