DESCRIPTION:
BRIEF SUMMARY
SPECIFICATION
The invention relates to a depilation device as part of a slaughtering line, especially for the slaughtering of hogs, consisting of a depilation beater consisting of elastomeric material with preferably embedded strength carriers, said beater substantially being a rectangular basic body, with a starting zone A, an end zone B, and a center zone C, whereby the starting zone A is thicker than the end zone B, and additionally, bores are present within zones A and B; a screw-on zone made of metal, to which the thicker zone A of the basic body is screwed, whereby the depilation beater is rigidly joined by means of the bores and a screw-bolt system, as well as by a clamping plate; a stop, against which the depilation beater supports itself via the baffle stool at extreme deformation; as well as of angle-shaped scrapers made of metal, which are arranged on the front side (working side) of the depilation beater within zone B whereby a solid anchoring is accomplished by means of the bores and a rivet joint (U.S. Pat. No. 2,604,656).
A device is also known from US-A-15 318 (FIGS. 1 to 3), in which the depilation beater has, on the front side (working side) where the scrapers are located, a belly-shaped elevation, namely within the zone of the stop present on the back side. Said elevation is fitted with hollow chambers extending in the cross direction of the beater, and/or with slots arranged in the longitudinal direction of the beater. Said hollow chambers or slots are intended to facilitate the bending deformation. It is a drawback here that the weakening of the material caused by the hollow chambers or slots leads, at extreme bending deformation, to the formation of cracks on both sides, thus rendering the depilation beater unusable, which is illustrated particularly by FIG. 3 of US-A-15 318.
In the meantime, a change has been made in that the basic body of the depilation beater is designed in such a way that its starting zone A is thicker than its end zone B, whereby reference is made to U.S. Pat. No. 4,907,317 (FIG. 1) with respect to said basic concept. In this connection, longitudinally and diagonally extending reinforcing ribs are arranged on the working side, where the scrapers are located, namely in the center zone C.
With the devices shown in the three aforementioned published references, which describe the ready-for-operation condition, the depilation beater, however, does not have any baffle stool, whose presence is of important significance within the framework of the device according to the invention.
Now, the object of the invention is to make available a baffle stool that it not subject to any wear (e.g. formation of cracks) even at extreme bending deformation.
This object is achieved by a depilation device in that at least one fluted groove extending in the transverse direction is present within the zone of the beginning of the baffle stool.
Usefully, the baffle stool has a plurality of fluted grooves, particularly two to five fluted grooves. Furthermore, it is advantageous in this connection if the fluted grooves have a varying depth and/or width, whereby the depth and the width increases toward the end of the baffle stool.
The invention is now explained on an exemplified embodiment by reference to the schematic drawings, in which:
FIG. 1 shows the back side of the depilation beater with the integrated baffle stool;
FIG. 2 shows the front side of the depilation beater with scrapers arranged whereon;
FIG. 3 shows a lateral view of the device ready for operation; and
FIG. 4 shows a lateral view of the depilation beater with the fluted grooves according to the invention.
FIG. 1 shows a depilation beater (1) made of elastomeric material (rubber or rubber-like material) with embedded strength carriers, said beater being a substantially rectangular basic body (2) with the zones A (starting zone), B (end zone) and C (center zone). On its back side (shown here), the depilation beater has, within zone C, a baffle stool (3), which is designed as one piece with the basic body (2) as an understru
