for a patent on a method and device for tying sausage casings

There are various methods and devices for unilateral Closing thin-walled sausage casings known in which one end of a tube section with Using a thread is tied (German Patent 926 295, DAS 106Ί 841). Here is a Thread that is cut in a predetermined length to tie a loop. mechanically around the to be tied End tied and the thread ends are then manually knotted into the loop. A machine is used for this Procedure not yet found.

Methods and devices for one-sided closing of thin-walled sausage casings are also known, where the folded end of the hose is closed with a metal clip. It is known to insert a loop in the clip fastener (German

Patents 835,266, 932,651, 964,570 and DAS 1 023 693). These clip closures can only be used to a limited extent because they are not the have the required strength.

In contrast, it is the purpose of the invention, a process or to create a device * that makes it possible to to create an absolutely firm tie knot with a loop, the length of which can be varied within wide limits is . The tying and tying of the loop should be feasible in a fully automatic workflow be .

This is achieved by the invention in that the sausage casing end is tied with double string is short and the two twine on one side of the tie knot made in a known manner are cut off, while on its other side an elongated end is formed on each of the two twine and these elongated ends of the string are knotted into a loop.

The elongated ends of the string can be knotted together during the binding process.

The invention also relates to an apparatus to carry out the procedure outlined above. the The invention is based on known binding devices and binding machines with the aim that the device according to the invention should also be suitable for subsequent installation in known binding machines.

Thus, a device for carrying out the method explained above is based on a known binding machine in which one prepares the tie knot and puts it around the folded sausage fillet Winding head and one the twine through a guide and hold eel nrich "; and a tensioning device for pulling the tie knot in a predetermined length past the winding head, as well as a Scissors that cut the string are provided. According to the invention, two thread bobbins are to be provided be, the thread pliers, the guide and holding device and the tensioning device for two parallel strings and the winding head to form a common tie knot with the two twine, furthermore the pad pliers with two in Vorziehrichtunpc with one Spaced behind one another arranged pairs of jaws, each of which takes up both twine,

and there should be an additional one to be introduced into the distance between the two pairs of jaws * of the thread pliers Knot ties may be provided.

This creates a fully automatic loop of the desired length at the same time as it is tied created forming device that does not have any significant makes additional machine effort necessary, which is not more difficult to operate. ^ sv.Oise than the well-known binding machines and which are characterized by particular operational reliability.

The device according to the invention can by exchange only a few machine parts and retrofitted by adding a few parts in known binding machines will.

It has been shown that in one of the prior art for tying the sausage casing end with only A tying device built into a thread on the thread tongs, the guiding and holding devices and the tensioning device no changes needed to be pre-arranged, to grab two threads instead of one, or to guide, hold or tension them. But it was necessary

that the distance between the guide device and the holding device was enlarged to take into account the fact that the thread pliers, as already said and will be explained further below, has two pairs of jaws instead of one and therefore takes up more space. It was also necessary to have the thread run-up curves on the winding head, through which the threads ST their movement direction get forced to change, as required by the juxtaposition of the two threads became. This inevitably resulted in a minor but necessary change to the parts of the winding head, which control its movements, through which it releases the path for the thread pliers and in the working position returns.

It had also proven to be useful to arrange the thread scissors so that the threads could be cut through going on inside the winding head. It was also advantageous to measure the length of the travel of the thread pliers within certain limits to be able to change arbitrarily, so that with the device loops of different Length could be tied.

the thread tongs 3 move from position B to position A shown in dashed lines, there picks up the thread 2 and moves with the thread 2 into position B. The clamping jaws ¹ J prevent the thread from deviating to the side and also cause a slight thread tension. Before the thread pliers 3 executes the movements explained above, the thread holder 5, the guide 6 and the winding head 7 have moved downwards in order to clear the path for the thread pliers 3. After the thread pliers 3 has reached position B again, thread holder 5, guide 6 and winding head 7 move upwards and remain in their original position. Thereafter, the winding head 7 forms the tie knot in a known manner by rotating. The amount of thread required for this is in turn withdrawn from the bobbin 1. After the binding process has been prepared, a pre-pleated hose section 9 is brought from pliers 8 into the winding head 7, the pliers 8 traveling from D to E, opening and closing again after enclosing the hose section.

At the same time pull the thread retraction rollers 11a and 11b the excess pad back in the direction of the bobbin 1 and thereby close the tie knot. To the binding

To increase the strength, the pad is firmly clamped by the suture holder 5 and the suture pliers 3, where the pad pliers still cover a short distance from B to C and thereby tighten the knot. Then the pad is cut by pad scissors 10, thread pliers 3 and 8 pliers open, and the hose section 9 is ejected from a machine part not shown.

After the knot has been formed, the pliers 8 pull the pre-pleated hose section 9 into the winding head 7. The winding head releases the pre-formed tie knot.

With the device it occasionally happens that only one of the two threads is in the desired manner is firmly knotted. As was also found in the context of the present invention, the occurrence succeeds to prevent this error if one of the pair of rollers serving as a clamping device, that is, of the Yarn retraction rollers 11a and 11b, at least one roller is articulated in such a way that the roller gap is wedge-shaped can be tapered. As has been recognized, the error is based on the occasional irregular Thickness of the binding threads and occurs when those located in the gap between the thread retraction rollers Sections of the two binding threads differ in thickness from one another to such an extent that the thread with the thinner part in the case of rigid mounting of the pair of rollers is not clamped sufficiently by this and consequently the knot tied with this thread will not be tightened. The aforementioned articulated Storage of at least one of the rollers allows the roller pair even if the thickness of the two is very irregular Binder threads remain fully effective.

One embodiment of the articulated roller assembly is in fl. 'la shown and their effectiveness in Fig. ^ b

illustrated. In this embodiment, the lower roller 11b of the two pad retraction rollers 11a and 11b is fixedly mounted and driven. The upper roller 11, however, is mounted so that it can not only perform the required for regulating the roller pressure moves from top to bottom, but it is also, as shown, such pendulum suspension, that, in the passing through the axes of both rollers level can commute. If the parts of the two threads that are finely clamped between the two rollers are of the same thickness, then they prevent the upper roller 11a from swinging out of the normal position, and the gap between the two rollers is consequently of the same width (FIG. 4a). But if the parts of the pinched between the rollers threads 2a and 2b different from each other, thickness, it comes automatically to the example shown in Fig. ¹ Jb swinging out of the upper roller 11a, is obtained by which that both the thicker thread 2a and the thinner threads 2b remain clamped evenly and strongly.
