This invention relates to a removing method and an automatic removing device.

(Conventional technology) When making eel flakes or canned fish, etc., if the fish is processed without removing its internal organs, the fish will not only rot easily, but the meat will smell and taste bad, reducing the value of the product. . Therefore, in order to make high-quality bonito flakes and canned fish, it is necessary to remove the internal organs before processing the fish.

However, in the past, there was no suitable machine for removing the head and internal organs of the fish, so workers inserted a ring with a cutting edge and removed the fish.
After holding the fish by its tail and cutting the abdomen with the cutting blade, the head is picked up from the ventral side and removed from the body, the internal organs are pulled out from the abdominal cavity with the head still attached, and the head and internal organs of the fish are removed by hand. ing.

(Problems to be Solved by the Invention) In the above-mentioned conventional manual work, the worker's fingers are damaged, making it impossible to continue working for a long time, and the work efficiency is poor (and recently, The current situation is that there is a shortage of such workers and it is becoming difficult to secure workers, which is a problem.

Ru.

At an intermediate position during the transfer, the fish (A) moves to the guide blade (6).
), the small fish (a) passes under the guide blade (6) without hitting the guiding blade (6), as shown in Figure 6.

However, the larger the fish (A) becomes, the more the guiding blade (6)
Since the guide blade (6) is guided to make a deep cut into the fish (A), the fish (A) is guided into the fish (A) within the guidance range W. Depending on the cutting depth (d) and (e), the fish (b) moves in the following direction depending on the cutting depth (d) and (e), and regardless of the size of the fish (a), the cutting edge (9)
, is in a fixed position opposite α[.

As shown in Figure 8 (bl), when the fish (A) enters and passes between the upper and lower cutting blades (9) and ClO, the boundary between the body and the head of the fish (A) is the cutting edge (9), C1
The cut is made as shown in Fig. 9 in the cutting direction (to) shown by the solid line in Fig. 11, and the spine (as shown in Fig. 8 (C1)
The middle part where the fish (b) and esophagus (c) are located is left intact, and the meat on both sides of the fish (a) is cut to approximately the same depth.

Next, when the cut portion passes through the bending passage 07J between the head pressing piece (11) and the lower base plate (8), the first
As shown in Figure 0, the spine (b) is broken and separated by the head-depressing piece OI) and the lower platen (8), while the esophagus e→, which is strong and rubbery and has a large tensile strength, is not torn and is slightly inserted into the abdominal cavity. It is pulled out from inside, adapts to the bending passage α■, and passes through the bending passage αa.

Thereafter, the esophagus (/→) moves along the upper edge of the lower platen (8) within the passage α■, and the fish (A) is transported.

At the rear end of passage 0, the body and head of the fish (a) are placed on the stand (3) and the head, respectively, with the esophagus (c) of the fish (a) caught on the upper edge of the lower table plate (8). Since the receiver is pushed downward by the stand (4) K, the viscera is pulled out from the abdominal cavity with the viscera still attached to the head, and the body of the fish (A) and the head with the viscera are separated as shown in Figure 12. The body is an endless conveyor (37+
It falls upward and is conveyed to the rear of the machine by the endless conveyor I3η, and the visceral head falls on one side of the lower bed plate (8).

At that time, depending on the type and size of the fish (A), the guide blade (6) can be moved into the fish (A) by operating the bolt device and adjusting the shaft control vertically or rotationally. Fish by notch (a)
The length of guidance in the forward direction changes to determine the type of fish (a),
Regardless of the size, etc., the boundary between the body and the head of the fish (A) is always in a fixed position facing the cutting blade (9) and α.

Also, depending on the type of fish (A), if the bolt e11 is operated to rotate the drive chain wheel to one side or the other as appropriate, the endless conveyor band (2) with the stand (4) will rotate accordingly. As the body moves, the correspondence relationship between the body part (3) and the head holder (4) changes, so as shown in Fig.
) and the head rest are placed side by side on the stand (4), the angle of inclination of the fish (A) with respect to the direction of movement of the fish (A) changes. Therefore, the cutting direction of the fish (a) is adjusted in accordance with the type of fish (a) in such a way that it is easy to pull out the internal organs and the yield is good.

(Effect of the invention) This invention has the following remarkable effects.

(1) When the fish are placed one after another on the endless conveyor belt, with the body part placed on the stand and the head holder placed on the stand, the fish will be transferred automatically, and the fish's head and internal organs will be attached to the body while the fish's internal organs are attached to the head. This improves work efficiency.

(2) During the transfer of fish, the upper guide blade, which is inclined in the direction of fish movement, cuts into the fish and automatically moves the fish in the forward direction according to the depth of the cut. The larger the fish, the more it moves depending on its size, and regardless of the size of the fish, the boundary between the fish's body and head is always in the fixed position and fed between the upper and lower cutting blades.

Therefore, regardless of the size of the fish, the fish is always cut at the boundary between the body and the head and the head is removed along with the internal organs. can do.

(b) Regardless of the size of the fish, the head is removed from each fish so that as little flesh as possible is left on the head to increase the yield of the body.

(3) Manpower is saved.

(4) No technology is required, it is easy to use, and anyone, even amateurs, can work properly.

(5) Work can be done uniformly from beginning to end, and the product is clean.
