It is characterized by being arranged horizontally or vertically in a state in which the tracing roller lines up the surface of the fish body being fed on the surface plate, and the truncated conical cutter cuts out the fins of the fish body. The skin removal device has a plurality of cutters arranged at different angles on the surface plate for cutting and removing the skin of the fish body, a control means for controlling each cutter in the cutting direction, and a control means for controlling each cutter in the cutting direction. is equipped with a sensor roller that detects the skin curve of the fish body in the feeding direction, and the control means controls each cutter in the cutting direction based on the skin curve detected by the sensor roller, The surface blood removal device has a substantially cylindrical cutter rotated by a motor arranged parallel to the surface plate and slightly protruding toward the fish body side than the surface plate,
The cutter is characterized in that its position can be adjusted in the cutting direction, and that the rear part of the cutter on the surface plate is interlocked with the cutter so that its surface is always flush with the cutting edge surface of the cutter. .

[Effect]

In the automatic processing apparatus for frozen fish bodies according to the present invention, the fish bodies placed on the surface plate are sent along the surface plate by the feeding mechanism, and are sequentially processed by the vertebral bone removal device, the fin removal device, the epidermis removal device, and the surface blood removal device. At this time, the vertebral bones of the fish are removed by the vertebral bone remover, the fins of the fish are removed by the fin remover, the epidermis of the fish is removed by the skin remover, and the surface blood is removed by the surface blood remover. Surface blood is removed.

Hereinafter, the operation of the fish body feeding mechanism and each device (vertebral bone removal device, fin removal device, epidermis removal device, and surface blood removal device) will be specifically explained.

(1) Fish feeding mechanism The fish placed on the surface plate is pushed by a fish pusher fixed to the conveyor and moved on the surface plate. When the fish reaches a predetermined position near each device, the fish holding roller descends to hold the fish, and during this time each device processes the fish. When the fish passes the fish holding roller, the fish holding roller rises and prepares for the next fish.

(2) Vertebral bone removal device The vertebral bone portion of the fish body on the surface plate is cut and removed diagonally using a tip saw placed at an angle. The amount of the cut is adjusted by adjusting the position of the tip saw in the direction of the cut.

(3) Fin removing device When a fish with fins is sent over a surface plate, a tracing roller placed near the surface plate is pressed against the surface of the fish and traces the surface of the fish. On the other hand, a truncated conical cutter adjacent to the tracing roller cuts the fish body according to the tracing roller and removes the fins of the fish body.

(4) Skin removal device When a fish body with skin is fed over a surface plate, a sensor roller detects the skin curve of the fish body in the feeding direction. Control means for each cutter controls each cutter in the cutting direction based on the skin curve of the fish body detected by the sensor roller. That is, when the fish body passes, each cutter advances and retreats in the cutting direction to cut and remove the skin of the fish body at a constant depth following the curved surface in the feeding direction of the fish body. A plurality of cutters are arranged at different angles, and each cutter shares a different angle range of the skin. Therefore, when the fish body passes through all the cutters, the epidermis is completely removed.

(5) Surface blood removal device When a fish with surface blood is sent over a surface plate,
The surface blood of the fish body is removed by a substantially cylindrical cutter disposed parallel to the surface plate and slightly protruding toward the fish body side from the surface plate. The amount of cut made by the cutter can be finely adjusted by adjusting the position of the cutter. When the cutter is finely adjusted in the cutting direction of the cutter, that is, in the direction of adjusting the cutting amount, the rear surface plate also moves in the same direction and the same distance in conjunction with the cutter, and the surface of the rear surface plate moves in the direction of the cutter. It is kept in the same plane as the cutting edge surface. That is, as shown in FIG. 23, the surface of the rear surface plate 12a is always aligned with the cutter 425.
It is kept on the same plane as the cutting edge surface. Due to this,
Blood on the surface of the fish body 17 is uniformly removed without tilting when passing through the cutter. Incidentally, as shown in FIG. 22, when the rear surface plate 22 is on the same plane as the front part of the cutter on the surface plate (the right part in FIG. 22), when the fish body 17 passes the cutter 425, Fish holding roller 2 in front of the cutter
1a rises and the fish holding roller 2 behind the cutter
When 1b descends, the fish body 17 tilts back and forth, and the blood on its surface cannot be removed uniformly.

It is placed so that it protrudes slightly to the side. The cutter 425 is preferably a helical cutter. This is because the depth of cut of the cutter 425 is small, for example, about 2 mm, so by using a helical blade, chips are continuously generated and can be easily discharged. The chips slide down the chute 426 below the cutter 425 and are discharged. Note that when the cutter is arranged parallel to the vertical surface plate 13 as shown in FIG.
It is expressed as 25'. ), each fish body pusher 18' is a vertical rod-shaped body, and the passage window 1 formed on the horizontal surface plate 12 is

〔Effect of the invention〕

According to the present invention, since the fish processing work is automated, the operator is freed from harsh and dangerous work, and the efficiency of the fish processing work is dramatically improved.
Furthermore, the labor cost required for fish processing work is significantly reduced, making it possible to reduce work costs.

(1) Fish Feeding Device According to the present invention, a fish placed on a surface plate is pushed by a fish pushing tool and moves on the surface plate, and is held down by a fish holding roller during processing work. That is, during the processing operation, the fish body is reliably conveyed while being held down. Therefore, it becomes possible to perform fish processing work reliably.

(2) Vertebral bone removal device Vertebral bones are removed using a tip saw, resulting in a cleaner cut surface compared to manual cutting, which increases the commercial value of the fish. In addition, since the tip saw can be adjusted in position in the direction of the cut, it can sufficiently accommodate variations in the position, size, etc. of vertebrae in the fish body.

(3) Fin removal device In the fin removal device, the fish body is profiled, so the fins are precisely cut. Additionally, compared to manual cutting, the cut surface is more beautiful and the product value is improved.

(4) Skin removal device Because the skin is always removed at a constant depth regardless of the shape of the fish body, the cut surface is finished more neatly than when done manually, increasing product value and reducing the yield of removal work. improves.

(5) Surface blood removal device Surface blood is removed by a roughly cylindrical cutter rotated by a motor, resulting in a cleaner cut surface than when done manually, and increasing the commercial value of the fish. Furthermore, since the surface of the rear surface plate is kept flush with the cutting edge of the cutter, the surface blood is removed uniformly, and the yield of the removal work is also improved. In addition, since the amount of cut of the cutter can be finely adjusted, even if there is variation in the thickness of the surface blood on the fish body, this can be adequately coped with.
