Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for performing three-grated fish so that the abdomen does not touch the body.

[0002]

2. Description of the Related Art An apparatus for sandwiching a fish body between the back and the abdomen and cutting two blades along the back bone and the abdomen along the midbone to lower the fish into three blades is disclosed in Japanese Patent Laid-Open No. 2-234634. Bulletin,
It is publicly known by others, and it is possible to divide a fish body into a middle bone and both bodies.

However, in the above-mentioned device, since the abdomen of the fish is cut out together with both bodies, in the present day when a fillet without abdomen is required, the abdomen must be scraped off from both bodies using a kitchen knife. is there.

[0004]

The problem to be solved by the present invention is that it is not possible to prevent the abdomen from sticking to the body of three grated fish.

[0005]

According to the present invention, a plate is inserted into the abdominal cavity of a fish body from which the internal organs have been removed, and the abdomen is pressed against the plate from both sides by means of a member so that the left and right abs are parallel. After correction, cut a thin knife along the abdomen to the abdomen, and also cut a thin knife along both sides of the midbone on the dorsal side. How to cut into one piece and two pieces on both sides of your body,
And a plate that is inserted into the abdominal cavity of the fish from which the internal organs have been removed, a restraining member that presses the left and right abdomen against the plate from both sides to correct the left and right abdomens in parallel, and cuts the abdomen along the abdomen to cut the abdomen. The problem is solved by a structure provided with a blade for separating the bone from the body and a blade for cutting the middle bone from the body by cutting into the back along the middle bone.

[0006]

According to the method and apparatus of the present invention described above, a plate is inserted into the abdominal cavity of a fish body which has been pretreated for removal of internal organs as shown in FIG. When the left and right abdomen are pressed down, the abdomen deforms due to pressure and adheres to the inserted plate, so that the abdomen inside the abdomen is also stretched straight along the plate surface and parallel to each other. Corrected, the cross-sectional shape of the fish body is a, b,
Even if the positions of C and D are different as shown in FIG. 5, the shape of the abdomen is uniformized due to the above-mentioned correction action, and if the fish body is bent, this should also be straightened. Be corrected.

Then, a pair of blades are cut into the abdomen on both sides along the outside of the abdomen, and a pair of blades are cut in the back along both sides of the spine. Since the bones and the body of the back are separated by a knife, three pieces of fish are automatically cut into one piece, which remains with the middle bones, spine and abdomen connected, and two pieces on both sides with no bones. It is done.

FIG. 8 is a schematic side view of a continuous device using a conveyor.

In the figure, reference numeral 1 denotes a fish body, and a spinal column 2 passes through the central portion thereof, and a row of vertebral bones 3 is projected from the spinal column 2 on the back side and the ventral side, and the abdominal cavity c extends along the inner wall thereof. Two rows of abdominal bones 4 are protruding.

Reference numeral 5 denotes a plate to be inserted into the abdominal cavity c of the fish body 1, which is placed with its thickness slightly thinner than that of the spine 2.
It is formed so that the outer sides of the abdominal bones 4 and 4 are aligned with the outer side of the spinal column 2 when the abdominal bones 4 and 4 are pressed against both sides thereof, and this plate 5 is used for a conveyor chain or a turntable described later. Install.

Reference numerals 6 and 6 are a pair of restraining members for restraining the abdominal portion b of the fish body 1, which are made of a plate material having a length and a width matched with a portion of the abdominal bone 4, which can be swung to the advancing / retreating means 7, 7. When you attach the shaft 8 to and move it toward the fish body 1 side by the advancing and retracting means 7 and 7,
The left and right abdominal parts b and b are uniformly pressed against the plate 5 from the chest side to the abdominal end regardless of the change in the cross-sectional shape of each part, and the curved abdominal parts b and b are deformed straightly. Also straighten the abs 5, 4 and correct them so that they are parallel to each other.
