2. Description of the Related Art Such a device itself is NL-A-8.
It is known from 602219 (corresponding to EP-A-0,258,939).

While this known device works well enough in practice, the problem that the position of the tail of the fuselage is not accurately determined when the device is actuated and, or additionally, a cylindrical cutter The depth of penetration depends on the relative position of the torso with respect to the device, which can be excessive, which can lead to rectal damage and fecal leakage. Sometimes.

[0004]

The object of the present invention is to eliminate these problems.

[0005]

SUMMARY OF THE INVENTION According to the invention, the above object is achieved by adjoining the end of one guided carrier which is movable parallel to the direction of movement of said cylindrical cutter, adjacent said cylindrical cutter. Achieved by a pressure element arranged, which is a U-shaped pressure stirrer for gripping around and pushing down on the tail.
irrup).

Preferably, the pressure stirrup member is housed inside the support stirrup member around an axis of rotation that lies at right angles to the longitudinal axis of the carrier and has a downwardly flanged end edge. , Further separated from the carrier by spring tension.

In one of the preferred embodiments, two pressure plates are mounted on the carrier, with a pressure stirrer member between them, and arranged at right angles to the direction of movement of the carrier. ..

Moving with a portion of the carrier inside the functional unit, indicating the relative position of the carrier with respect to the functional unit, limiting the travel of the positioning element relative to the functional unit. A first element forming a reference is preferably mounted on the elongated carrier which is guided longitudinally inside the functional unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A functional unit 2, which is the subject of a device as described in NL-A-8602219, has one frame 4 and is a rotary drive blade type cutter 10 housed in a housing 12.
Is supported in the frame so as to move in the direction of arrow 6 under the action of the operating cylinder 8. Below this cutter 10 there is one spherical positioning and closing element 14 for insertion into the rectum of the animal carcass. This element 14 is mounted on an elongated carrier rod 16 and can be moved in the direction of arrow 6, independent of the movement of the cutter 10. A cylindrical cutter 18 is concentrically arranged around the carrier rod 16 and is housed in a protective sleeve 20. The cutter and sleeve are fixed to the frame 4 and thus move with the frame 4.
The movement of the carrier rod 16 is transmitted to a rod 22 (see FIG. 3) which is in line with the carrier rod 16, the rod 22 having a stop member 24 at its rear end, which stop member 24 is provided with said stop member 22. Placed at right angles to, its function will be described in more detail below.

The movement of the carrier rod 16 and thus of the rod 22 is caused by proper control by an air cylinder (not shown).

Up to this point, the device according to the invention is
-Generally in agreement with the device known from 8602219. However, one of the major differences with this known device is the presence of the carrier 28 mounted in the frame 4.
This carrier 28 is slidable in the direction of arrow 6 and is connected to a rod 30 which is guided on the right side in the frame and thus follows the movement of the carrier 28.
It has two rods 26a and 26b. The rod 30 comprises two stop members. The first stop member is shown at 32 and interacts with stop member 24 on rod 22. The second stop member is shown at 34 and forms one follower cam. The follow-up cam 34 interacts with the control roller 36 of the switch 38. switch
38 is connected to the carrier rod 16 of the positioning element 14,
If it is activated, it stops its movement. The purpose of these two stop members and how they actuate will be explained in more detail below.

As shown in FIGS. 2a, 2b and 2c, the support rod 26
Each of a and 26b has one pressure plate on its front end.
Hold 40a and 40b. When the cutting unit is moved towards the animal torso, these pressure plates 40a, 40b will rest on the torso at positions on either side of the anus of the torso, as will be described below. These pressure plates 40a, 40b
Is a U-shaped stirrup member 44 via the connecting plates 42a, 42b.
Hold. A second U-shaped stirrup member 46 is accommodated in this stirrup member 44, and legs 48a, 48b of the stirrup member 46 are accommodated.
Are connected to holding plates 42a, 42b via connecting plates 50a, 50b so as to pivot about axes 52a, 52b. The front ends 54a, 54b of the legs 48a, 48b are bent downwards and the two tension coil springs 56a, 56b pull the stirrup member 46 in the direction of arrow 58.

The device of the present invention operates in much the same manner as the known device described above, but as a result of the presence of the movable tail pressure stirrer member 46 and the control function performed by its carrier, There are differences. The manner of operation of the device of the present invention will be described with reference to Figures 4a to 4f.

These figures show a pig's torso 70 suspended by hind legs 72, which has a flank 74, anus 76 and pubis.
It has a 78, a rectum 80, a spine 82, and a tail 84. Figure 4a shows
The situation where the functional unit 2 is moved in the direction of arrow 86 toward the body is shown. FIG. 4b shows how the movement is stopped when the unit 2 is at a certain distance from the fuselage and has reached the position shown. At this time, the stirrup member 46 puts the tail 84 in a downward fixed position so that the pressure plates 40a, 40b press against the fuselage and the tail 84 cannot impede subsequent operations. By moving in the direction of the arrows 88, 90 shown in Figure 4c,
The positioning and closing ball 14 seeks the anus. Upon finding the anus, this ball 14 enters the rectum (driven by an air cylinder not shown) until it reaches the position shown in Figure 4d. The distance that the ball 14 enters the rectum is determined by the distance that the carrier 28 is pushed back into the functional unit 2. The stop member 32 (FIG. 3) moves to the right in this case, while the stop member 34 connected to the carrier rod 16 moves during the movement of the positioning ball until the stop member 24 abuts on the stop member 32. Move to the left. This stroke of the locator ball 14 is indicated by "b" in Figure 4e. Finally, the entire functional unit comprising the rotary drive cylindrical cutter 18 and the rotary drive blade cutter 10 has moved forward over a distance indicated by "a" in Fig. 4e, which distance "a" also , The carrier 28 is determined by the distance it has been pushed back into the functional unit 2. Since the stop cam 34 also moves to the right with this carrier, this stop cam interacts with the feeler 36 as described above. This feeler 36 moves to the left with the functional unit and is connected to a switch (not shown), which the feeler 36 has a projection 34 on.
When it hits, the movement of the functional unit is stopped.
Finally, the cutting blade 10 along with its carrier 10a moves forward in the direction of arrow 90, cutting the pubis 78 in the process.

Thereafter, these various components return to their initial position.
