DESCRIPTION OF THE PREFERRED EMBODIMENTS The work of peeling the skin (2) of a carcass (1) such as a cow is performed while the carcass (3) is suspended with its head (3) down. This is performed through the steps of the first to third stages (see FIG. 1). Carcass (1) is the first stage (4)
As (pre-processing), the skin around the hind leg, the front leg, and the neck is peeled off with a knife, and the skin of the abdomen (5) of the carcass is split along the height direction.

In a second step (6), the other parts are peeled off using the gripper (8) supporting the frame (7) and the backrest (9), leaving the back skin of the carcass.

In the third stage (10), the peeled skin is connected to a rope (11) such as a chain, and the rope is wound down by a winding drum (12) to remove the peeled skin. Peel off.

The peeling operations of the first to third stages are performed using a work table (13) as described later.

The first and second stages are described with reference to FIG.
This will be described with reference to FIGS. The frame body (7) has an upper rail (14) having an I-shaped cross section and a lower rail having a T-shaped cross section.
A pair of columns (16), (16) supported by (15), and the columns (16),
(16) It has the frames (17) and (18) passed between them.

A wheel (19) is provided on the upper part of the columns (16), (16).
The column is supported by being suspended from an upper rail (14), and a roller (20) is provided below the column to allow the frame to run. The upper rail
(14) is fixed to a support rail (21) supported on the ceiling.

In front of the frame (right side in FIG. 2), a carcass moving rail (22) fixed to the support rail (21) is provided. Trolley traveling along (23)
Then, the carcass (1) is hung using a hanging tool (24) such as a bifurcated hook so that the carcass can be transferred to the front of the frame.

The carcass (1) transferred to the front of the frame (7)
, The back is located on the side of the frame, and the backrest (9) is applied to the back of the carcass.

At this time, the contact member (2) of the backrest (9)
The frame (7) is moved in the horizontal direction so that (5) and (25) are located substantially at the center of the back of the carcass, and the backrest (9) supported by the frame is moved vertically. Move and adjust. After adjusting the horizontal position of the frame (7), a bolt (28) is passed through a screw portion (27) of a support rod (26) provided at a lower portion of the frame, and the bolt is fixed to a fixing member ( 85) and fastened with a lock nut (29).

In the illustrated example, the backrest (9) can be moved in the left and right direction (in FIG. 2) by a hydraulic cylinder (30) and a guide rod (31) provided on the back side, and a frame body is provided. (7) A hydraulic cylinder having one end connected to a frame (33) movably provided in a vertical direction via a guide rod (32), and the other end connected to the frame (17) of the frame. (3
5) makes it possible to move up and down. The backrest (9) is supported by the frame (33) and the support member (34).

The pretreatment of the first stage of peeling and the second stage of peeling are performed with the backrest (9) applied to the back of the carcass (1).

In the peeling of the second stage, the skin end formed by tearing the abdomen of the carcass is gripped by the gripper (8), and the hydraulic cylinder (36) on the back side of the gripper is operated to cut the skin end. Pull to the back of the carcass and peel. In addition, when gripping the skin end by the gripper (8),
The gripper (45) is closed by operating a hydraulic cylinder (44) provided on the gripper.

In this case, since the backrest (9) is provided on the back of the carcass, the skin on the back of the carcass remains without peeling.

Hydraulic cylinder (36) on the back side of the gripper
Is a frame of the frame (7) with one end on the gripper and the other end on the frame.
It is connected to a support plate (37) fixed to (33). The support plate is provided with a support member (38).

The gripper (8) is connected to the balancer (42) via the pulleys (40) and (41) supported by the frame (39) by a wire (43) and suspended in a suspended state. Has become.

Next, the peeling of the third stage will be described with reference to FIGS. By operating the hydraulic cylinder (44) provided on the gripper (8), the grip portion (45) holding the skin is opened. Then, the gripper (8) and the backrest (9) are moved to the left (in FIG. 5) by operating the hydraulic cylinder (30) and the hydraulic cylinder (36), respectively.

In this state, a part of the peeled skin on the foot side is grasped, and this part is put into the loop (47) of the shackle chain (46) as shown in FIG. When the shackle chain is used, the skin is not damaged, so that the quality of the skin is not deteriorated.
The hook (48) of this shackle chain (46) is engaged with and connected to a rope (11) such as a chain that can move vertically in the vicinity of the back of the carcass, and The body is wound downward by the winding drum (12) and the remaining skin is peeled. The winding drum is driven by a driving device (49) including a hydraulic motor and a speed reducer such as a worm gear or other driving devices.

One end of the cable body (11) is fixed to the hook (50) of the support rail (21), and the other end is connected to pulleys (51), (52),
(53) through the contact members (25), (2) of the backrest (9)
5), it is wound around a winding drum (12) via a guide drum (54), and the other end is fixed to the winding drum. The pulleys (51) and (52) serve as moving pulleys.

The guide drum (54) is provided with a concave portion (55) substantially around the central portion thereof, and guides the rope such as the chain into the concave portion.

Although the guide drum is provided in the embodiment, the guide drum may be omitted. At this time, the width of the winding portion of the winding drum is narrowed, and the rope is moved substantially in the center of the drum. It is good to wrap around.

In the shackle chain (46), a string, a wire, a hook or other connecting means can be used in place of the shackle chain. If these are made of stainless steel, they do not rust and are therefore sanitary.

The operations in the first to third stages are shown in FIGS.
This is performed using a work table (13) as shown in FIG. Workbench
(13) a work table (57) with handrails (56), a lift (58) for supporting the work table so as to be able to move up and down, and a carcass suspended and supported by the work table. And a slide table (59) formed so as to be able to be extended to the vicinity of both sides of the slide table.

As shown in FIG. 10, a ramp (62) having a handrail (60) and a step (61) is provided on a side surface of the work table. Instead of this ramp, a ladder is provided. Is also good.

The work table is raised and lowered by pressing a foot switch (63) provided on a work table (57) and operating a hydraulic cylinder (64) of a lift (58).

A method of extending the slide table (59) will be described with reference to FIGS. 9, 11, and 12. The slide table (59) includes a floor plate (65), an operation frame (67) containing a hydraulic cylinder (66), and a linear rail fixed to the outer surface of the operation frame with bolts (68) and nuts (69). This linear rail is provided with a frame of the work table (57).
(71) Linear guide bearing (7
3) is engaged. The hydraulic cylinder (66) in the operation frame
Has one end on the support plate (74) provided on the operation frame and the other end on the floor plate (6
Connected to 5).

Feeding out and out of the slide table
Is a switch (75) fixed to the handrail (56) of the work table
To operate the hydraulic cylinder (66) in the operation frame (67). At this time, the upper side of the handrail (86) provided on the slide table (59) is the handrail (5) of the work table (57).
6) Insertion guide to upper side.

The floor plate (76) of the slide table has its tip bent obliquely upward and a round bar (77) is fixed to the upper edge of the floor plate, so that it is safe to prevent workers from sliding down. Is being planned.

The operation of the gripper (8), the backrest (9), the winding drum (12) and the like is performed by an operation panel (78) located on a work table (13). In the hydraulic path,
Hydraulic tank, hydraulic pump, control panel, modular hydraulic valve
(79), a relay box (80), and the like. The modular hydraulic valve (79) is provided on a gantry (87) fixed to the frame.

A water sprinkler (81), a water-soap tub
A hand washer (83) and a shower (84) provided with (82) are provided and can be used to remove stains on hands and the like before and after peeling.

[0035]

According to the present invention, since the work table having the work table, the lift and the slide table is provided, the slide table can be peeled off as close to the carcass as possible when peeling. Therefore, work is easy.
