Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic carcass cutting machine developed for the purpose of mechanically cutting carcasses, which had conventionally been done manually.

The carcasses of pigs and cows obtained by dissecting the skin etc. are
It is divided into three parts: , middle (Para), and lower (Ude). Previously, the students had to leave the school hanging on a conveyor and use a handsaw or knife to first cut off the udes, then cut the paras, and then remove the peaches by hand. This work was hard work because the carcasses were heavy, and one person could normally process about 60 animals in half a day. The factory, which processes about 360 cows in half a day, required about five workers.

The present invention enables the above-mentioned work to be carried out by one person with heavy labor, and its structural features include supporting the feed rail in the route of the carcass transport trolley, A chucking device is provided on the feed rail so that it can move forward and backward while holding the back part of the carcass, and rotary saw teeth are provided that can be adjusted at positions to divide the carcass into three parts: the top, the bottom, and the thigh.

The stones are explained in detail using the drawings below.

FIG. 1 is a front view of the device, and FIG. 2 is a left side view. In this device, the carcasses (indicated by two-dot chain lines) (1) are suspended in pairs on hangers (4) by trolley rails tv (2) K t Ketatoro IJ- (3) running on the top of the device. It is transported in a suspended state from 11 to the left in Figure 1. The hanger (4) is a square shaped fitting with carcass locking ends at both ends. Such a hanger is used to transport the carcass (1) to the front of the chucking device (6) of the present device while being hooked onto a hook (5) provided on the trolley (3).

At this point, connect the hook (5) of the trolley (3) to the hanger (
4) and allow the chucking device (6) to feed the carcass (1). For this purpose, the hanger receiving cylinder a4) (see Figure 2) installed on the top of the chucking frame (9) of the chucking device (color) operates, and the hanger receiving lever (a4) connected to it operates with the axis αe as its fulcrum. Rotate to a nearly horizontal position and lift the hanger. In this state, when the hook release cylinder αη, which is also attached to the top of the chucking frame (9), is activated, the shaft (to)
extends and pushes the hook (5) outwardly and removes it from the hanger (4).

The chucking device (color) has the function of moving toward the rotating sawtooth (7) while holding the carcass, thereby enabling stable cutting. Therefore, the chucking device has the following structure. First, trolley rail (2)
A horizontal horizontal feed rate tv (8) in the longitudinal direction is provided in the main body position below the trolley rail μ in the route of the trolley, and a chucking frame (
9) For K, install one wooden chuck arm at the top and two at the bottom (1
0a), (10b), and (10C) are provided in pairs on the left and right sides, respectively. These chuck arms (j Qa) ~ (10
C) has three cylinders (
11a) to (11C). The compressed air necessary for opening and closing the cylinders (11a) to (11C) is opened and closed by operating the operation button (a). Then, when the worker presses one of the operation buttons (2), the para part of the carcass is held. In this state, the upper part of the device (top right of Figure 1)
It is sent in the direction of the rotating sawtooth by a head feeding cylinder (to) provided at K.

In addition, the shaft tip of the head feed cylinder (to) is fixed to the top of the chucking frame (9).
The chucking device (6) can be moved forward or backward by operating the head feed cylinder (2). At the bottom of the chucking device decoy, as shown in Figure 1, there is a tank for compressed air that is sent to the various cylinders used in this device.

At approximately the center of the head feed cylinder (to) and the device described below, a band-shaped rotating sawtooth (7) is stretched between the drive wheel holder and the driven wheel lv@.

The drive wheel 1L/Kan is driven by the motor 1L and reduction gear 4 on the front of the device. The driven wheel A/@ is supported toward the main body of the device by a serrated cylinder.

The endless band-shaped rotating sawtooth (7) stretched between the drive wheel lv) and the driven wheel A'@1) can divide the carcass (1) into six parts, each into rub, para, and thigh.

When carcass (1) is divided into three parts, the quality of each divided part is different, so it is necessary to adjust the cutting position as much as possible according to the difference in quality. Therefore, we created a structure in which both the lower and upper cutting lines can be adjusted vertically or tilted. Therefore, four lower cutting line adjustment rollers (E) are provided at the front and lower parts of the device body, and these rollers (To) (C) can be adjusted up and down, respectively, by upper cutting line adjustment cylinders (E) and (E) attached to the main body. There is. Similarly, an upper cutting line adjusting roller v)@ is provided for adjusting the upper cutting line, and is moved up and down by an upper cutting line adjusting cylinder cls@.

The carcass (1) held in the chucking device (6) is moved to the rotary sawtooth (7) section by operating the compressed pneumatic feed to the head feed cylinder (to) at the top of the device. At this point, it will be cut by rotating saw teeth.

The bottom rub (1a) then falls to the bottom, and the unloading board -
is carried out to the front of the device.

The carry-out plate bell is a plate body that can be rotated by a fulcrum, and when the rub (1a) falls by a carry-out cylinder provided on one side, the carry-out plate is rotated to carry out the rub (1a).

The rib meat (1b) and the thigh meat (1C) are also cut along the upper cutting line at the same time when cutting the love r1a) meat. The thigh meat (1C) is on the hanger (4
), so it won't fall, and the head feed V
Operate the cylinder α and move the chucking device (9) to the first position.
Move it to the right side of the figure and place the chucking device on the roller conveyor for conveying thin meat installed on the right side of this device! ! When (6) has advanced, operate the V-linders (11a, 1 to (11Q)) for moving the chuck arms (10a) to (10C) to open the chuck arms (10a,) to (10C), Parameat (
1b) is placed on a roller conveyor and conveyed.

Directly above the roller conveyor, a thigh meat conveyor sleeve is provided on an inclined surface. A hanger receiving lever is rotatably provided at the tip of the thigh meat conveying rail, and is rotated in the vertical direction by a lever operating cylinder 035). When the lever (4) with the thigh meat (1C) suspended reaches this position, operate the lever operation lever ■ to make the hanger receiving lever diagonally upward, and press the hanger receiving cylinder α When the hanger (4) is turned downward, the hanger (4) will be locked to the hanger lever with the thigh meat (1C) suspended. The meat is then transported along the slanted thigh meat transport rail.

The operation of the chucking device (6) for receiving the carcass (1) from the trolley (3), the operation of receiving the hanger (4) from the hook (5) by turning the receiving lever, and the chucking device (6) in the direction of the rotating sawtooth. ) and various operations for transporting cut rubs, thighs, and buffed meat are all performed by cylinders. These cylinders can be operated by a worker using the operation box Q according to the timing of their operation.
By pressing the operation button provided at 361 or by pressing the button provided for operating the chuck arm described above, the electromagnetic valves etc. can be opened and closed to perform the respective operations.

However, these cylinder operations and rotary saw blade operations are controlled by a box ■! The advantage of the present invention is that it can be operated almost without human intervention due to the automatic circuitry built into it. It is one. The automatic circuit for this purpose is constructed by employing ON-OFF control circuits conventionally incorporated in various automatic devices in accordance with the above-mentioned operation, so a description thereof will be omitted.

Although the present invention has a complicated structure as described in detail above, when it is used, it is simply a matter of operating a switch, and the continuous cutting work is a heavy labor of simply monitoring, and it can be carried out by only one worker. Capable of cutting carcasses. Therefore, it greatly contributes to improving work efficiency and hygiene.
