The invention relates to a device for dividing packages from a filled tube or from sausages from a strand of sausage filled with one piece of sausage by closing scissor arms which rotate around an axis They can be pivoted towards one another and are angled to form a receiving recess.

Such devices are known from DE-PS 10 99 438 and DE-AS 15 86 210. the However, the first-mentioned known device has the disadvantage that it is used to form a plait-like Pinch-off point, as it is necessary for setting a locking chamber, only for hoses or strands are suitable up to a limited diameter. Namely, if strands of larger diameter - for example over 55 mm - which have to be tied off like a braid, are very long closing distances required, which have the disadvantage that either more time is required for the constricting process or when faster closing the constriction would take place too suddenly, reducing the risk of Hose damage would be caused. In addition, this would become an undesirably large one Lead dimensioning of the constriction and drive units. According to DE-AS 15 86 210 by arranging further scissor arms which can be pivoted about their own axes towards the pinch point be resolved. It has been shown that with such a device, although all occurring Hoses or strand diameters can be properly pinched off that the required constructive However, effort is relatively large and that the additional scissor arms also an additional Require set-up and maintenance effort. That being said, the device works that way more complicated and therefore more prone to failure. μ

From FR-PS 14 54 225 it is when using two scissor arms to close sausages known that in the closed state the constriction point with the center of the sausage passage opening coincides in the open state, so that in both situations the same distance from the pivot axes is present. Therefore, there are essentially the same disadvantages as in the aforementioned prior art Technology. From FR-PS 14 54 225 it is also known that the scissor arms are also in full when open, overlap at the ends of their tips which are angled towards one another.

The task, therefore, is a task according to the aforementioned DE-AS 15 86 210, in which the receiving recess through to the seer arms displacer edges located is limited and when the seer arms are open, an approximately circular one Has constriction residue opening so that it can also be used for strands with a larger diameter are suitable without the structural effort increasing disproportionately and without the closure paths and the closing times have to be selected disproportionately larger.

According to the invention, this object is achieved in that the scissor arms are also fully open State overlap at the ends of their tips angled towards one another and that the The center of the sausage passage opening is further away from the pivot axis of the scissor arms than the center of the constriction opening in the closed state. It has surprisingly been shown that by the measures according to the invention not only the difficulties mentioned in two-armed Pairs of scissors can be overcome in a simple manner, but also the risk of damage of the hose or strand no longer exists at the constriction point.

In a further development of the inventive concept, it has proven to be advantageous if at the end of the Tip of one of the scissor arms angled towards each other a guide for the one with this cooperating second scissor arm is provided.

Further details and advantages of the invention are illustrated in the figures Embodiments explained in more detail. It contains

From Fig. 1 it can be seen that in the conventional devices, the scissor arms 2, 2 'with their tips 16 and 17 stand apart when fully open. The scissor arms angled to form receptacles 1.1 ' 2, 2 'are 3 μm to encompass a certain imaginary circular opening cross section Opened 85 degrees, with the through the pivot point 4 and the bottom 18, 18 'of the receiving troughs I, 1' laid Straight lines are used. The displacement edges 6, 7 and 8, 9 of a scissor arm are here Executed largely at the same distance from an arc, which is at the distance of the reasons 18, 18 'from Pivot point 4 runs around this. In the completely closed state, the reasons 18, 18 'are included

'the point 19 together, which is at the same time the center point of the imaginary circular opening cross-section 3. \ The distance between pivot point 4 - center is 19 mm in the selected comparison example 145th This ^known: design leads, among other things, that the inner and outer ι shear angle 5, 5 'are not elected evenly \ can and DNSS example in halbgesehiussenep. i State there are considerable differences Γ (cf. 100 degrees / 120 degrees).

Smaller than the distance " b " between the center 19 of the sausage passage opening and the point of rotation 4. In addition are the ends 12,13 of the angled towards each other

ι Tips of the scissor arms 2, 2 'also overlapping in the fully open state and with a guide 14 educated. Together with a changed contouring of the displacement edges 6, 7, 8, 9, the measures according to the invention result in the following advantages:

a) the opening angle can be reduced from 85 to 70 degrees,

! b) the inner and outer shear angles 5, 5 'remain the same over the entire sealing path,

c) the closing path or the closing process is corresponding to the smaller opening angle shorter,

d) the overlapping scissor arms 2,2 'are not larger than the ones that do not overlap after can because of aer us di'iniicrem Μηι ^ ιϊ?.!

3 shows that in a conventional device the distance from the center 19 of the öffnun.frsqiii r section 3 - Pivot 4 would have to be increased from 145 to 168 mm in order to work on the smaller one

ίο opening angle of 70 degrees and the same shear angle 5, 5 'to come. Of course, the shear arms 2, 2 'also have to be enlarged accordingly, which ultimately also leads to larger drive units, because heavier parts have to pass through one larger way to be moved.

A comparison of FIGS. 4 and 5 shows further advantages of the inventive device over the conventional device when using two axially displaceable pairs of scissors 20, 21 for attaching two locking clips 10, 11 at the same time. While according to FIG. 4, the scissor arms are comparatively thick will.; -, nuts, so that they are not bent during the closing process, they can be chosen thinner thanks to the U-shaped guide 14. The consequence of this is that the closure clip 10 can be placed much closer to the filled hose section 15 to be closed, as a result of which a more plump filling is achieved and the risk of air inclusions is avoided. The difference can easily be seen by comparing the dimensions χ and y.

F i g. 6 finally shows an enlarged illustration of the detail "A" from FIG. 5 with the two scissor arms 2, 2 'and the guide 14 in section.
