Description

[Detailed description of the device]

[0001]

[Industrial field of application] This is a bone and meat separation method used to separate bones from meat for cut-off sections of pigs, cattle, whales, fish, etc. Regarding the machine.

[0002]

2. Description of the Related Art Conventionally, for example, as a bone-flesh separating tool for a rib of a pig, a loop made of Tegus is attached to a handle,
It is generally used that an operator holds the above-mentioned handle and hooks the loop on the tip of the abdominal bone, and then pulls the handle strongly to squeeze the bone with the loop, thereby separating the bone bound to the meat. ing.

[0003]

However, since the conventional bone-and-mesh separating device requires a considerable amount of force for the separating work, many workers have the drawback of damaging their shoulders and elbows. It was rare.

The object of the present invention is to obtain a power-driven bone and meat separator that enables the health of workers to be maintained.

[0005]

As a means for solving the above-mentioned problems, the present invention is to install a loop made of a flexible wire in a guide tube so that the loop can be moved forward and backward from the tip of the guide tube. The bone meat separator is proposed in which the base of the inner loop is connected to a loop traction fluid pressure cylinder, and the reaction force receiving locking member at the time of the above-mentioned loop traction is projectingly provided at the tip of the above-mentioned guide cylinder. An embodiment of the present invention will be described below with reference to the drawings.

EXAMPLE In FIG. 1, a rectangular parallelepiped slide piece (2) is slidably inserted into a rectangular guide tube (1) having both ends closed, and one side portion of the slide piece (2) is inserted. , The base of the loop (3) made of high-strength flexible wire having appropriate rigidity such as Tex, steel wire, etc. is connected,
The loop (3) extends through the front end plate (4) of the guide tube (1) and the tubular cover (5) provided on the front surface of the front end plate (4) and extends toward the front of the guide tube (1). When the above loop (3)
Has a length such that the slide piece (2) partially projects from the cover (5) even when the slide piece (2) is retracted to the rearmost part, and the cover (5) is provided below the front end cover (5) of the guide tube (1). ) And a reaction force receiving locking plate (6) that hangs at a right angle and a pressing plate (7) with a lip (8) that extends forward at a right angle to the locking plate (6) and has an appropriate width. The L-shaped member is fixed, and locking projections (9) are formed on the lower side of the reaction force receiving locking plate (6) as shown in FIG.

A support leg (1) is provided on the upper surface of the guide tube (1).
0) and (10) are provided in a protruding manner, and a hollow cylindrical handle (11) is fixed to the supporting leg.

In this case, the entire guide tube (1) is made to have such a size and weight that an operator can hold the handle (11) and freely carry it.

The traction drive device for the loop (3) is as follows. In FIG. 1, as an example, the case (13) is attached to the lower surface of the work table (12) on which the bone and meat separation work is to be performed.
And install the air cylinder (14) in the case (13).
Is installed and one end of a flexible rod (15) such as a steel wire is connected to the tip of a piston rod (14 ′) of the cylinder (14), and the flexible rod (15) is connected to the case (1).
The brackets (16) and (17) of 3) are slidably mounted in a flexible tube (19) having one end connected to the bracket and the other end connected to the rear end plate (18) of the guide tube (1). The other end of the flexible rod (15) is inserted through the guide tube rear end plate (18) and connected to the other side of the slide piece (2).

As an air supply circuit for the air cylinder (14), a direction switching valve (20) for supplying air to the cylinder (14) is attached to a side portion of the cylinder (14), and the direction switching valve is also provided. A pilot air switching valve (21) for operating (20) is attached to the front end of the handle (11), and a lever (22) for operating the pilot air switching valve (21) is attached to the handle (11). A spring (23) is provided which extends downwards and constantly springs the lever (22) in the valve closing direction.

The air sent from the air source through the hose (24) passes through the branch pipe (25), the hose (26) and the air direction switching valve (20) and the pilot air switching valve (21).
Respectively, and a hose (27) is further connected from the pilot air switching valve (21) to the air directional switching valve (20), and from the air directional switching valve (20) to the rod side of the cylinder (14) and. Hoses (28) and (29) are connected to the head side, respectively. Details of these air circuits are as shown in FIG.

The operation of the above example is as follows. An example of separation of bone meat from the abalone bone in the pork loin portion will be described. First, the loin portion (A) is placed on the work table (12) with the ribs facing upward as shown in FIG. Then, the operator holds the handle (11) and lifts the entire guide tube (1), and attaches the L-shaped reaction force receiving locking plate (6) to the spine of the spine (a) and the holding plate (7). Abutting on the spine (a) respectively, in that state, the tip of the loop (3) is hooked on the tip of the rib (b) as shown in FIG. 4, and then the lever (22) of the pilot air switching valve (21). When the valve is pulled, the switching valve (21) is switched, and the air of the air source is supplied to the hose (2
4), through (26) to (27), the air direction switching valve (2
0) to switch the switching valve (20) so that the air of the air source is sent from the pipe (25) through the hose (28) to the rod side of the cylinder (14) to move the piston of the cylinder (14). Retracting, thereby pulling the flexible rod (15) to slide the slide piece (2) backwards in the guide tube (1), with which the loop (3) moves backwards along the ribs (b). Pulled and squeezed the avalanche bone (b) to separate it from the meat. Meanwhile, the locking plate (6) locks on the spine (a) and receives the tensile reaction force of the loop to effectively perform the separating action.

Then, when the lever (22) is released, the pilot switching valve (21) is switched to the original closed state by the spring (23), which acts on the air directional switching valve (20). The air in the hose (27) that had been used is discharged, and the air directional control valve (20) is switched to the original state,
Then, the air of the air source is sent from the pipe (25) through the hose (29) to the head side of the cylinder (14) to advance the piston, thereby advancing the slide piece (2) through the flexible rod (15). Then, along with this, the loop (3) is pushed out forward from the front end of the guide tube (1) for a long time.

When the work of separating one rib is completed, the loop (3) is hung on the next rib and the same operation is repeated.

EFFECTS OF THE INVENTION According to the bone-flesh separator of the present invention, it is possible to strongly separate the bone-flesh by using the pressure fluid as a power, thereby maintaining the health of the worker.
Moreover, in operation, by locking the reaction force receiving locking member in place, it is possible to receive the reaction force at the time of pulling the loop and perform an effective separation operation.
