Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for skinning a cow carcass in a slaughterhouse.

[Conventional technology and problems]

BACKGROUND OF THE INVENTION Conventionally, there are two methods for disassembling a cow after slaughter at a slaughterhouse, as described below.

The first method, which has been practiced for a long time, is to slaughter a living cow and then perform operations such as removing the internal organs, removing the head, and skinning the cow while the carcass is lying on the floor. This method involves lowering the cow carcass to the floor and hoisting it back onto the hanging rail for subsequent work, which requires a lot of time. Processing time cannot be accelerated. Furthermore, in such a method, the above-mentioned processing operations are carried out with the cow carcass lying on the floor, resulting in contamination of the cow carcass, which poses a major hygiene problem.

In order to solve these problems, a second means as described below was developed. That is, this method is a means for processing a cow carcass while suspended from a rail, and hygiene and work efficiency have been significantly improved through assembly line work and division of processing work.
In particular, by dividing the work, it became possible to use machines efficiently in each work process, so the overall processing time was significantly shortened.

However, in this mechanization, there is a big problem in the use of various skinning machines in the process of skinning cow carcasses. This is because the various skinning machines that were technologically introduced from other countries completely ignore the actual situation of domestic meat production and the special characteristics of Wagyu beef, and focus solely on the efficiency of skinning. These skinning machines pull and peel the skin with a force greater than that of a cow carcass, so the fat layer and meat layer of the cow carcass separate, creating a gap, and the fat is removed from the carcass. Since a large amount of carcass adheres to the skin that has been removed from the carcass, not only does the yield of meat become poor, but the appearance of the carcass also deteriorates.

In addition, when washing the carcass with water, the fat layer is pulled with great force during skin removal, so there are some spots where water can penetrate into the fat layer, like water bladders. Since the carcass is carried away with the carcass still attached to the skin, there is a problem in that the surface of the carcass becomes uneven, making it even more difficult to drain the carcass.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and it solves the problems of the conventional technology by simple and rational means. Alternatively, the cow carcass can be neatly skinned by hand using an air knife, and the work can be performed on a work floor in a fixed position while rotating the cow carcass at the required angle using a horizontally rotating rail. It is an object of the present invention to provide a working device that allows for easy peeling work by lifting and lowering, with high efficiency, without compromising commercial value, and with a high yield.

[Structure of the idea]

The structure of the present invention that solves the problems of the conventional technology is as follows:
After slaughtering a cow, at least both hind legs of the decapitated cow carcass are suspended from a trolley that runs along a rail line constructed in a building, and the above rail line system is used. A separated horizontal rotating rail section of a required length is provided in this rail line at a desired location, and this horizontal rotating rail section is provided above this horizontal rotating rail section and is A cow carcass skinning workshop is provided, which is suspended from a rotating body with a speed reducer motor that rotates by a required angle by manual operation, and the cow carcass is raised and lowered by manual operation from the cow carcass skinning workshop. It is characterized by the provision of a work floor.

〔Example〕

The details of the embodiments will be explained with reference to the drawings.

Figure 1 is a partially cutaway front view, Figure 2 is a side view of the same as above, Figure 3 is a plan view of the same as above, Figure 4 is a partially cutaway side view of the main part, and Figure 5 is an example of the arrangement of the peeling device. FIG.

Reference numeral 1 denotes a plate-shaped rail with a vertically long cross-sectional shape, and this rail 1 is installed in a building, and as shown in FIG. 5, with a cow carcass 2 suspended by a trolley 3, It is used to transport carcasses to the processing workplace. As shown in FIG. 1, horizontal rotating rail portions 1a separated from the rail 1 by a required length are provided at required locations on the rail line constituted by the rail 1.

On the other hand, a frame 5 mounted on a beam 4 bridged over the building is placed above the horizontal rotating rail portion 1a. A guide rail 6 having a ring-shaped planar shape is provided inside the frame 5, and a rotating body 7 having a cross-shaped planar shape is provided on the guide rail 6. Mount the wheel 8. The horizontal rotating rail portion 1a is suspended from the lower side of one of the cross-shaped members constituting the rotating body 7 via a rail hanger 9, and the horizontal rotating rail portion 1a is connected to the rotating body 7. This allows them to rotate together.

On the frame 5, there is a motor 1 with a speed reducer that can be operated manually by the worker on the work floor, which will be described later.
0 is provided, and its drive shaft 11 is connected to the center of the rotating body 7. Figure 4 shows a generally used trolley 3, which has rolling wheels 3b that roll while engaged with the rail 1 against the main frame 3a, and a cow carcass 2 at the lower end.
and a hook 3c that is pierced through the foot of the person.

Although not particularly shown, when the trolleys 3 on which both legs of the cow carcass 2 are suspended enter the area of the horizontal rotating rail section 1a, the trolleys 3 do not come off the horizontal rotating rail section 1a. Of course, it is necessary to provide a stopper mechanism on the lower surface of the rotary body 7 to make this happen, and also to provide a regulating member to align the horizontal rotating rail portion 1a with the axis of the rail 1 after the peeling work is completed. Of course. Since the stopper mechanism described above can be of a structure that is generally used in other parts of this type of rail line, a detailed explanation will be omitted.

Reference numeral 12 denotes a stand erected on the floor at a position corresponding to the horizontal rotation rail portion 1a;
A work floor 13 is attached which can be raised and lowered as desired by means of a lifting device (not shown) built into the work floor 2. The lifting and lowering of the work floor 13 and the rotation of the speed reducer-equipped motor 10 are performed by manual operation by the worker on the work floor 13, that is, by a switch mechanism provided on the stand 12. Further, in the front part of the work floor 13, there is an arcuate recess 13a into which the cow carcass 2 can fit.
is formed.

[Effect]

Next, the peeling work will be explained.

A cow carcass 2 that has been slaughtered and whose internal organs have been removed, or whose viscera have not been removed and whose head has been removed, is sent to a work site with its hind legs suspended from a rail 1 by a trolley 3, as shown in the figure. It will be done. When both trolleys 3 intervene in the horizontal rotating rail section 1a,
A stopper mechanism prevents both trolleys 3 from moving outward. Then, a worker gets on the work floor 13 and moves the knife up and down while moving the work floor up and down.
Alternatively, remove the skin using an air knife or the like.
After a part of the skin has been removed, the rotating body 7, the horizontal rotating rail section 1a, and the cow carcass 2 are manually operated.
is rotated by a desired angle to remove the skin from the unpeeled portion.

〔effect〕

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Since the cow carcass is suspended on rails and the skin is skinned manually, there is no unsanitary contamination like in the past, and there is no fat or fat on the skin like in mechanical skinning. It is possible to obtain a carcass with high yield and high commercial value without removing the meat quality.

(b) Since the cow carcass can be rotated by the horizontal rotation rail part by the desired angle of the work, the operator can skin a large cow carcass in a fixed position, and Since the work floor can be raised and lowered at will, skinning work from high to low places on cow carcasses can be done in a comfortable posture, reducing worker fatigue.
Good work efficiency.
