Description

  The present invention is a carcass such as cattle and pigs dismantled for food, and is transported to each processing station by a carcass transporting trolley that runs on a rail that is hung by a crotch and is installed near the ceiling of a processing facility. In particular, the present invention relates to an apparatus used in a processing line for performing a disassembly process, and more particularly to an apparatus for removing thigh meat from a crotch.

  In the slaughterhouse, in order to suspend and transport the carcass in the carcass transporting trolley, the lower ends of the two arms that extend obliquely downward with the apex angle in between are formed in an outwardly upward bowl shape. A crotch is used. And the top part of this crotch is suspended and supported by the trolley for carcass conveyance, and also a limb leg is pierced and conveyed to the right and left buttocks of the crotch. Only the pair of split thigh meat portions are conveyed in a suspended state to the disassembly station at the end of the processing line.

  Therefore, in the last disassembling operation, it is necessary to remove the pair of thighs that have been suspended and conveyed from the crotch from the crotch, and this has been done manually.

  Naturally, the removal work of the heavy thigh meat suspended in such a high place is dangerous and heavy labor, and its mechanization was envied. Therefore, for example, in the carcass removing section in which the carcass hung from the left and right hips of the crotch suspended from the carcass transporting trolley is transported, the left and right V to be engaged with the left and right inclined arms of the crotch respectively. An upper and lower two-level locking member having a letter-shaped locking groove on a horizontal line, an openable and closable clamp arm that presses and fixes the crotch against each locking groove of the upper and lower two-level locking member, and the crotch A carcass removing member that is supported so as to be able to reciprocate in the direction in which the carcass hung on the collar is removed from the collar along the outer periphery of the bend of the collar, and drive means for reciprocating the carcass removing member An apparatus for removing carcass from the crotch has been proposed (see Patent Document 1).

  However, since the carcass removing apparatus disclosed in Patent Document 1 operates above the thigh meat that has been conveyed, there is a concern that the meat may be contaminated due to falling oil, accumulated dust, rust, or the like attached to the apparatus. Therefore, it is necessary to clean frequently, but the conventional apparatus has a complicated structure, and there is a problem that the manufacturing cost, initial cost, and running cost increase.

  Therefore, the inventors can not only improve the safety of work and significantly reduce human labor, but also perform the work with a simple apparatus structure and without requiring a lot of labor for cleaning management. A possible “animal thigh meat removal device from the crotch” has been proposed (see Patent Document 2).

This device includes a liftable chute disposed below a crotch suspended from a carcass transporting trolley that runs on a built-in rail, and an up-and-down chute disposed on the chute and the top of the crotch. A guide portion that is formed in a convex shape having a larger apex angle than the corner and guides the thigh flesh away from the buttocks of the crotch by pushing up the thigh meat while avoiding the crotch as the chute rises Furthermore, the following excellent effects can be obtained by providing a crotch presser ring that presses the arm of the crotch from above and restricts the movement of the crotch as the chute rises.
(1) The safety of thigh meat removal work can be improved, and human labor can be significantly reduced.
(2) It is possible to prevent the meat from being contaminated by the falling of foreign matters such as oil, dust and rust.
(3) The apparatus structure is simple, and the manufacturing cost, initial cost and running cost are both economical.
(4) With the crotch arm presser ring, it is possible to correct the shift due to the weight difference between the left and right thighs suspended from the crotch, and the crotch is steady, and the rising guide part interferes with the crotch. Crotch can be avoided without this.

  Normally, the size of thigh meat (hereinafter simply referred to as “meat pork”) that is removed at the livestock breaking station is about 50 cm long, but it is a large size of breeding pigs and sows that are over 70 cm long. Thigh meat (hereinafter referred to as Onuki) may be processed. At that time, at a meat processing center where the height of the thigh meat transport rail (ie, ceiling height) is not sufficient, the crotch position is changed upward to ensure the height from the floor to the bottom of the thigh meat. I am doing so.
