An arm 24 projecting in the direction of the fixed rod 12 and curved in the lower direction is set to the frame unit 2 so that the top part of the arm 24 may come almost on an extension line of the fixed rod 12. A contact part 25 is set to the top part of the arm 24 so as to face to the engagement piece 15 and a rod 1a of the air cylinder 1 is connected through a string 18 to the tilting rod 14. A fixture piece 7 is fixed to the frame unit 2 and a mechanical valve involving a push bottom switch 8a is attached to the fixture piece 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for peeling the scapula from the shoulder meat of edible animals such as pigs.

[0002]

2. Description of the Related Art Conventionally, the work of peeling off the scapula from the shoulder meat of pigs, which are food animals, first cuts the tendon by inserting a knife or the like from the joint part, and then separates the bone and meat from the scapula. It is done by inserting a stick into the back of the and raising this stick by hand.

[0003]

As described above, since the conventional peeling work is performed by the worker himself and requires a great deal of force, the physical burden on the worker is immeasurable, and There was a problem that anyone other than boys could not adapt to this work. For this reason, there has been a long-felt demand for the development of a device that can easily separate the scapula of the scapula. In view of the above problems in the prior art, the present invention reduces the physical burden on the operator, and even a person other than a young boy can easily perform the scapula peeling work of an edible animal. The purpose is to provide a device.

[0004]

Therefore, according to the present invention, a scapula peeling device for an edible animal is provided with a cylinder device, a frame body coaxially provided at the tip end of the cylinder device, and a tip end of the frame body. A fixed rod that extends in a right-angled direction and is fixed, a tilting rod that is tiltably connected to the fixed rod, a locking piece provided at the tip of the tilting rod, and a substantially extending line of the fixed rod. With a contact portion provided to face the locking piece, a cord body that connects the rod of the cylinder device and the tilting rod, and a valve device that operates by a switch operation and sucks the rod of the cylinder device. It is designed to be configured.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of a scapula peeling device for an edible animal according to the present invention, FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a sectional view taken along line III-III of FIG. 1, and FIG. 4 is an enlarged view around a tilting rod. A front view, FIG. 5 is a plan view thereof, and FIG. 6 is a side view of a locking piece.

As shown in FIG. 1, the air cylinder 1 includes
A cylindrical frame 2 is attached coaxially with the air cylinder 1, and a rod 1a of the air cylinder 1 is expanded and contracted in the frame 2. The air cylinder 1 is provided with a connecting portion 3, a vertically movable chain 5 is connected to the connecting portion 3, and the apparatus main body A is hung in a work space so that the apparatus main body A can be used only during work. It is designed so that you can bring it to your workbench.

As shown in FIGS. 1 and 3, an L-shaped attachment piece 7 is fixed to the frame body 2 in the middle thereof, and the attachment piece 7 is a mechanical valve having a push button switch 8a. 8 is attached. Then, the push button switch 8a is pushed and the mechanical valve 8 is operated to drive the air cylinder 1 to suck the rod 1a. A first grip portion 27 is provided at the tip of the mounting piece 7,
The first grip portion 27 can be held by the right hand when the scapula B is peeled off.

As shown in FIGS. 1, 4 and 5, an L-shaped connecting piece 9 is fixed to the end of the frame body 2, and the connecting piece 9 has bolts 10 and 11. Fixed rod 1 through
2 is attached. A pin 13 is installed on the tip of the fixed rod 12, and a tilting rod 14 is attached to the pin 13.
The base end of the is pivotally supported. The tip of the tilting rod 14 is provided with a hook-like locking piece 15 (see FIG. 6) that can rotate in a direction substantially perpendicular to the tilting rod 14, and the locking piece 15 allows the shoulder blade B side. The joint part "b" is locked (FIGS. 4 and 5). Further, the tilting rod 14 is provided with a roller 1 via a pin 16 at the tip thereof.
7 is rotatably attached so that a cord 18 to be described later can be attached to the roller 17.

As shown in FIGS. 1 and 2, the air cylinder 1
The rod 1a is provided with a cord locking portion 19 at the tip thereof, and a pin 20 is provided on the cord locking portion 19. A roller support 21 is provided in the middle of the connecting piece 9, and a roller 23 is rotatably attached to the roller support 21 via a pin 22. A ring-shaped cord body 18 is attached to the pin 20, and the cord body 18 passes under the roller 23 and is provided at the tip of the tilting rod 14.
It is attached to 7. As a result, the air cylinder 1
When the rod 1a is sucked, the cord 18 is pulled rightward in FIGS. 1 and 4, and the tilting rod 14 can be tilted in the standing direction (two-dot chain line in FIGS. 1 and 4). As described above, the string 18 that connects the tip of the rod 1a and the tip of the tilting rod 14 is passed under the roller 23 located below the rod 1a. Even when sucking and pulling the cord 18, since only a vertically downward force acts on the rod 1a and no bending force acts, the rod 1a may be damaged even after long-term use. There is no.

As shown in FIG. 1, the frame 2 is provided with an arm 24 projecting toward the fixed rod 12 and curved downward, and the tip end of the arm 24 is fixed to the fixed rod 1.
It is located on the extension line of 2. In the arm 24,
A contact portion 25 is provided so as to face the locking piece 15, and the joint portion d on the humerus D side can be brought into contact with the contact portion 25 (FIGS. 4 and 5). ). still,
The arm 24 is provided with a second grip portion 26 so that the second grip portion 26 can be held by the left hand when the scapula B is peeled off.

Next, the operation of peeling the scapula from the shoulder meat using the apparatus of this embodiment will be described. First, shoulder meat E
Place on a workbench and insert a knife or the like from the joint to cut the tendon. Next, the joint portion d on the humerus D side is brought into contact with the contact portion 25 at the tip of the arm 24, and the joint portion b on the scapula B side is locked by the locking piece 15. When the tilting rod 14 is fixed to the scapula B in this way, the right hand holds the first grip 27 and the left hand holds the second grip 26. Then, the push button switch 8a of the mechanical valve 8 is pushed and operated by the thumb of the right hand. Then, the mechanical valve 8 operates, the air cylinder 1 is driven, and the rod 1a is sucked. As a result, the cord 18 is pulled rightward in FIGS. 1 and 4, and the tilting rod 14 tilts in the standing direction (two-dot chain line in FIG. 4). By the tilting motion of the tilting rod 14 in the upright direction, the shoulder blade B fixed to the tilting rod 14 by the locking piece 15 is separated from the shoulder meat E. With the above, the work of peeling the scapula B from the shoulder meat E is completed. In this way, the scapula B can be peeled off by a simple operation,
A person other than a young boy can easily perform the peeling work of the scapula B.

[0012]

As described above, according to the present invention, the scapula peeling device for edible animals is provided with a cylinder device, a frame coaxially provided at the tip of the cylinder device, and a direction substantially perpendicular to the tip of the frame device. A fixed rod that extends and is fixed to the fixed rod, a tilting rod that is tiltably connected to the fixed rod, a locking piece provided at the tip of the tilting rod, and the locking rod on a substantially extended line of the fixed rod. The contact portion is provided to face the piece, a cord body that connects the rod of the cylinder device and the tilting rod, and a valve device that operates by a switch operation to suck the rod of the cylinder device. As a result, the scapula can be peeled off from the shoulder meat by a simple operation, so that an excellent effect that even a person other than a young boy can easily perform the scapula peeling work.
