Method and device for cutting slaughtered chicks into parts.

5

The invention relates to a method for cutting slaughtered chicks into parts, wherein they are suspended from the legs on a transport system and are transported via various processing stations, where parts of the animals are cut off.

In the known method of cutting slaughtered animals into sections, cutting at the various processing stations was performed by butchers cutting off parts by hand, for example parts of the breast. Since this known method, because it was largely carried out by hand, was expensive, possibilities have been sought for at least part of the method using machines. to be carried out. ·. = ·

The object of the present invention is now to cut the breast meat by mechanical means.

For this purpose, the slaughtered chickens and suspended from the legs on the conveying system are brought back to a horizontal position approaching the horizontal position by means of an obliquely sliding chute during transport, and are subsequently transported in substantially this position between two blades rotating at some distance from each other. .

According to the method according to the invention, preferably the animals are divided into weight classes of-4.00 grams difference for cutting and the knives and the distance from back to sternum for each weight class are set in a predetermined anatomically determined position. . In this way it is possible to. obtain high cutting precision. For this purpose, the distance between the rotating knives is adjustable, for instance between 10 and 30 mm × 20 mm is a common size. Likewise, the chute is adjustable in height, as is the suspension height 8204223 ♦ t \ '... -2- of the transport system relative to the blades.

The invention further provides a device for carrying out the method, which device comprises a transport system with which slaughtered animals can be transported hanging on the legs 5 past processing stations, which are arranged such that parts of the slaughtered animals can be removed.

The processing station according to the invention comprises: a. An ascending gutter, seen in transport direction, in which an animal can be transported back to back; b. behind the highest part of the gutter two blades that can rotate in the opposite direction, practically horizontally; c. guides for bringing and / or keeping the animal to be transported and to be divided into a fixed position.

15 To obtain the required accuracy during cutting and / or a good adaptation to the weight class, one or more of the following dimensions can be set: 1; * a. the distance between the rotatable knives is such that the position remains symmetrical with respect to the gutter; b. the highest position of the trough relative to the plane of the blades; c. the distance between the suspension points (hooks) of the transport system in relation to the plane of the blades.

25 A V-shape of the gutter is good. The adjustability of the blades, of the gutter and of the suspension device serves, as already mentioned, to obtain an optimum effect with regard to the weight class (in other words to the size of the slaughtered animal). It is thus possible to remove parts of the breast with optimum effect.

The invention is explained with a drawing.

This shows with:

Figure 1. a side view of the processing station; Figure 2. a front view of the same processing station.

Both figures show with 1 a V-shaped gutter, in which the slaughtered animal, which according to figure 2 with the legs on 8204223 * 'V ♦. Hooks 2 of a schematically indicated transport device 3 hangs, gradually being brought into a more horizontal position according to the transport device indicated by an arrow.

Just beyond the end of the trough 1 are two blades 5 and 4 rotatable in opposite directions, which can be driven by Q, motors 5 and $. These knives cut off parts of the chest during transport.

As already mentioned, setting different distances is essential for optimal effect. These distances tO are determined anatomically and depend on the weight class / size. Therefore, the distance between the blades 4 and 4a mutually symmetrical with respect to the trough 1 is adjustable, for example from 10 mm to 30 mm, by means of a spindle 6 with handwheel and sliding blocks 7 and 7, with which the motors 15 5 and 5a and thus the knives 4 and 4a can be moved opposite to the gutter 1.

Likewise, the highest position of the gutter 1 is adjustable with the aid of a sliding piece 8. The same applies to the hooks 2, for which the height adjustment of the transport device 3 at the location of the knives 4 and 4a is adjustable by means of a diagrammatically indicated height adjustment device 9. '

In order to place or keep the animal in the correct position in the gutter during transport, a guide 10, 10a is provided on both sides above the gutter 1. A guide may also be present at the location of the knives 4 and 4a to keep the animal fixed transversely during cutting. It goes without saying that during transport the animal must hang in the correct position in front of the present device, that is to say with the back facing the chute 1. Of course, knives and motors must be shielded and plates 11 are present for cut parts to guide and dispose of.

The described device can in principle also be used as a so-called "line cutter". The position of the animal relative to the scoring knives must then be different, which is mainly found in a different position 8204223 * I * -4.- of the gutter and a different distance between the knives.
