Description

The present invention relates to a device for stripping the foliate fat layer of the abdomen from the skeleton of a carnivorous animal that has been slaughtered and has its internal organs removed and whose abdominal cavity has been opened, for example, the carcass of a pig.

What must be done in the processing of edible pig skeletons is the removal of the two fat layers on the left and right that appear along the inner surface of the half-body skeleton. These fat layers are also called "leaf lard" because of their leaf-like shape that grows from a relatively narrow part near the lower end of the skeleton with its hind legs suspended.

Reef lard is removed by grabbing the lower edge of the fat layer and then pulling upwards from the inside of the skeleton. An instrument using this method is shown in Patent Document 1, which is coupled with a vertical piston mechanism with an upward force to remove the leaf lard from the skeleton. One of the difficulties in this process is that as the width of the reef lard increases, it becomes increasingly difficult to separate the reef lard from the skeleton. This has the problem that when the force to pull the leaf lard is increased, the relatively narrow peeling start end of the leaf lard is sometimes torn.

It is described in Patent Document 2 that a solution to this problem is an automatic positioning lard removing device provided with a rotary drive head that wraps lard around the head. The wrapping action prevents the lard from breaking at the starting point of winding, making it an instrument that gradually provides better grip as the lard is wound. However, the problem with this fixture is that the lard must be removed from the fixture by sliding or winding the lard and pulling out the end of the head, or by manually rewinding.

Removing the lard wrapped by pulling it out of the head from the end of the instrument causes some problems. A significant problem is that this removal method limits the shape of the head. The head should be relatively smooth and shaped so that the lard can slide and be removed. This contradicts the requirement that the lard stick to the head in order to wrap the lard over the head. The instrument described in this patent document employs evacuation to adhere the lard to a relatively smooth head. Not only does this require a separate vacuum device, but the vacuum line extending to the head increases costs and complicates the device, limiting its means when setting it non-automatically.

In the automated process, it is necessary to relocate the instrument to the component that grips the lard in order to pull the lard from the end of the head. This takes time and delays the processing process. Further, it takes more time to manually rewind the lard from the head after the process is completed.

In Patent Document 3, the tool for removing the revers from the carcass (the body of the edible beast with the internal organs) is a head for mechanically engaging the lard, for rotating the head in the forward and reverse directions. Reversible drive device, trigger coupled to start rotating the head forward to operate the reversible drive device to wind the lard around the head, controller coupled to the trigger, automatically reverse rotation of the drive device After the trigger is released, it is equipped with a controller that rotates the head in the opposite direction so as to rewind the lard from the head. The head is preferably tuned to engage the lard and is disclosed with a plurality of hooks that position the head to prevent damage to adjacent meat.

As a device for removing abdominal fat or a layer of leaf fat from meat, for example, the device described in Patent Document 1 is a gripping device for grasping the abdominal fat or the layer of leaf fat and a device for pulling the fat layer away from the abdominal wall. It is equipped with a pulling device. And this gripping device is provided with at least one suction opening. The pulling device also comprises a rotationally driveable hoisting mandrel provided with at least one suction opening, which hoisting mandrel is abdominal fat or leaf fat gripped by the suction opening during rotational driving. Is guided by the rail 6 to wind up and remove the layer.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. For convenience, similar configuration requirements will be described with the same reference numerals.
As shown in FIG. 1, the foliate fat layer peeling device of the present invention is configured to peel off the clamp unit 1 and suspend it from a driving cylinder 13 via a suspension chain 12. At the upper end of the peeling drive cylinder 13, a pulley 13a that can move on the rail 14 that is bearing on the rail rotation shaft 14a and is rotatably attached to the left and right is attached to the lower end of the support column 15. The rail 14 is provided with a brace 16 so that the horizontal state of the rail 14 can be finely adjusted by adjusting the length of the turnbuckle 16a.

As shown in FIGS. 1 and 2, the clamp unit 1 handled manually is positioned by grasping the main gripping hand (handle) 6 and the auxiliary handle (stick) 5. The rear main gripping hand 6 is provided with a trigger 7, and the clamp 2 is opened and closed by pulling the trigger 7.

The clamp unit 1 is a device for peeling the foliate fat layer L from the pork carcass C hung by the hook 17 shown in FIGS. 10 and 11. In this case, the thoracic cavity and abdominal cavity of the pork carcass C are opened and the intestine is removed. The clamp unit 1 is guided by a rail 14 extending in a horizontal state by the upward movement of the peeling drive cylinder 13 in a state where the lower end portion of the foliate fat layer L is sandwiched by the clamp 2.

That is, the foliar fat layer peeling device of the present invention is a device for peeling and removing the foliate fat layer L from the carcass C of a meat animal whose abdominal cavity is pre-cut, and is a clamp unit that grips the foliate fat layer L. 1 and a peeling drive cylinder 13 which is a traction means for pulling the foliate fat layer L away from the abdominal wall, and a trigger 7 which can be pressed by a human finger to open and close the clamp 2 in which the clamp unit 1 opens and closes pneumatically. It is a thing. In this embodiment, air pressure is used as the driving pressure for the cylinder 13 and the clamp unit 1, but hydraulic pressure such as other gas or hydraulic pressure may be used.

The clamp unit 1 will be described in detail with reference to FIGS. 2 to 3.
The clamp 2 of the clamp unit 1 has a substantially horizontally long rectangular shape, and is composed of a movable blade 2a and a fixed blade 2b provided so as to be vertically openable and closable. Engagement groove 2c is engraved on the inner surface of the movable blade 2a and the fixed blade 2b so that the end portion of the foliate fat layer L can be reliably grasped. That is, by providing the uneven teeth 2c over the entire peripheral surface of the fixed blade 2b and by providing the stepped portion 2d on the back side of the meshing portion of the lower teeth, the teeth can be more reliably sandwiched. (See FIG. 7). Here, one end of the clamp movable lever 3A is fixed to the movable blade 2a and the fixed blade 2b, and the other end is by a clamp support shaft 3b, a link fulcrum 3c, a link fulcrum 3e, a link bar 3d, and a lever fixing arm 4 which are link mechanisms. It is connected to the clamp fixing washer 9a of the clamp rotation holder 9.
The uneven teeth 2c may be provided over the entire peripheral surface of both the upper and lower clamps 2a and 2b, and the step portion 2d on the back side of the meshing portion may also be provided on either one of the upper teeth or the lower teeth. It can be selected and adopted as appropriate.

A frame 8 equipped with a clamp drive cylinder 10 that can move the clamp 2 by air pressure is connected to the rear portion of the clamp rotation holder 9 via a frame fixing washer 9b. A main gripping hand 6 is attached to the lower side of the frame 8, and a trigger 7 that can be pressed by a human finger that opens and closes the clamp 2 is provided in the vicinity thereof.

The clamp 2 and the frame 8 are orthogonal to each other in the longitudinal direction thereof, that is, they are usually arranged in a T shape, but as shown in FIGS. 5 and 6, a bush (thrust) arranged inside the clamp rotation holder 9 is arranged. The clamp 2 and the frame 8 are rotatably connected to the left and right with the bearing) 9c as a boundary (see FIG. 3).

Here, FIG. 5 shows a method in which only the upper clamp movable lever 3A is movable and the lower clamp fixing lever 3B is fixed. In this case, an auxiliary lever 3a is required to move only the clamp movable lever 3A according to the protruding operation and the immersion operation of the cylinder rod 10a, but there is an advantage that positioning when sandwiching the lower end of the foliate fat L becomes easy. There is. On the other hand, in FIG. 6, since the pair of upper and lower clamp movable levers 3A are movable both up and down, the auxiliary lever 3a becomes unnecessary.

FIG. 9 shows another embodiment of the clamp unit 1, in which only the upper clamp movable lever 3A shown in FIG. 5 is movable, and the lower clamp fixing lever 3B adopts a link mechanism to be fixed, and the blade is used. The tip edge surfaces of 2a and 2b are greatly curved. As shown in FIG. 8 (b), the tip edge portions of the blades 2a and 2b of the clamp 2 may have a linear shape, but as shown in FIG. 8 (a), it is preferable to have a curved shape, that is, a curved shape. .. This is because the end portion of the foliate fat L inside the carcass is inclined, so that the end face of the foliate fat L can be grasped as a whole by abutting the tip of the clamp 2 along the curve. The blades 2a and 2b of the clamp 2 are not all but partly formed to be curved in a vertical cross-sectional view. Further, the tips of the blades 2a and 2b of the clamp 2 include not all but a part thereof being formed to be curved in a plan view.

12 to 15 show other embodiments of the entire foliar fat layer stripping device, and for convenience, the same components as in Example 1 will be described with the same reference numerals.

In this embodiment, as shown in FIGS. 12 and 13, the clamp unit 1 is fixed to the liner 19 which is slidably fitted to the rod rail 18 which can be separated from the trigger 7 and extends in the vertical direction. It is fixed via.

Then, as shown in FIGS. 14 (a) and 15 (a), when the trigger 7 is pulled to clamp the lower end of the foliate fat L, it is peeled off as shown in FIGS. 14 (b) and 15 (b). After the clamp unit 1 suspended from the drive cylinder 13 grips the end portion of the foliate fat layer L, only the clamp unit 1 portion is pulled up along the rod rail 18 as it is.

At this time, the peeling drive cylinder 13 and the clamp unit 1 are held by the clamp 2 at the lower end portion of the foliate fat layer L, and the rail 14 extends horizontally due to the upward movement of the peeling drive cylinder 13. Be guided. After the foliate fat layer L has been peeled off and removed, when the trigger 7 is returned, the clamp is released and the rod rail 18 is moved downward to return to the original position. In the figure, 18a is the upper stopper of the liner 19, and 18b is the lower stopper of the main gripper 6.

As shown in FIGS. 16 to 18, the rod rail 18 uses a pipe having a circular or rectangular cross-sectional shape, but a prismatic pipe having a rectangular cross-section is desirable in consideration of preventing the main gripper 6 from being used. Further, the rod rail 18 may have a solid rod shape instead of a pipe shape.
