Further, the rotary knife 2g with a cover in the kidney epidermis cutting device G is attached to the tip of the rotary lever 1g so that it is tilted with the lower end facing the conveying direction of the conveying device C when the rotary lever 1g is lowered. The upper end of the rotating lever 1g is rotatably supported by a pin 51g, and the lower end is urged by a spring 52g to rotate in the opposite direction to the conveying direction of the conveying device C. , and is attached to the rotating lever 1g so that rotation due to this biasing force is restricted by a stopper 53g. Therefore, with the lower end of the rotary knife 2g with a cover in contact with the spine 1x, the spring 52g follows the unevenness of the spine 1x as the fish is transported.
The tip thereof moves up and down while rotating in the conveying direction of the conveying device C against the urging force of. The rotary knife with cover 2g itself has a downwardly convex cylindrical curved body 32g.
The rotating knife 3g is provided at the lower end of the rotating shaft 33g, and the cover 4g covers the rotating shaft 33g.A cutting edge 31g is formed on the upper periphery of the cylindrical curved body 32g. The diameter of the cover 4g is the same as the cutting edge 31.
The lower end is formed with a downwardly convex curved surface which is larger than the diameter of g. Further, as shown in FIG. 17, the cutting edge 31g is positioned inside a common tangent line 34g between the surface of the cylindrical curved body 32g and the surface of the lower end of the cover 4g. Cover 4g and cylindrical curved body 3 are shaped like this.
By forming 2g, when the rotary knife 2g with a cover descends in an inclined state as described above and the tip of the cylindrical curved body 32g reaches the spine 1x, the surface of the lower end of the cover 4g and the cylindrical curved body 32g The contact portion of the kidney 112x against the surface of the kidney 112x is depressed, and only the relatively raised kidney epidermis 3x is cut in contact with the cutting blade 31g, and the abdominal cavity wall is not cut. Then, such cutting of the kidney epidermis 3x is carried out from the throat to the anus of the fish by transporting the fish by the transport device C, and the rotary knife 2g with a cover is moved by the rotary lever 1g regardless of the size of the fish. Before rising, the kidney epidermis 3x, which is difficult to remove near the anus with large irregularities where the spine lx rises, is further tilted against the spring 52g due to the abdomen near the anus of the fish being transported, and the lower end of 4g is covered. The guiding action allows for reliable cutting and smooth removal from the abdominal cavity. At this time, the shapes of the cover 4g and the cap-shaped curved body 32g as described above prevent the surface of the ventral tube near the anus from being cut by the cutting blade 31g. Incidentally, the tip of the cap-shaped curved body 32g is provided with a pointed portion 35g that contacts the backbone 1x of the fish body. Also, in Figure 16, 36
g is an air motor that rotates the rotary knife 3g at high speed.

Furthermore, the kidney removal device H in the automatic processing device is capable of damaging the kidneys of a fish in a laparotomy state in which the kidneys are semi-dressed, the internal organs other than the kidneys are removed from the abdominal cavity, and the epidermis of the kidneys is cut. As shown in Figures 19 and 20 in detail, a kidney removal and cleaning rod is attached to the tip of a rotary lever 1h for vertically moving the kidney removal and cleaning rod. Double cleaning rod-shaped body 2
h is provided so that its lower portion is rotatable in the conveying direction of the conveying device C against the urging force.

The rotary lever 1h in the kidney removal device H rotates about a shaft 13h in conjunction with a cam 12h via a cam lever 11h, and due to the rotation, the tip of the kidney removal and cleaning rod 2h is moved into the fish body. The body is lowered from above the open abdomen of the fish toward the spine lx (Fig. 18) near the throat of the fish, and while this downward state is maintained, the fish is transported from the throat to the anus, and the kidney 2x (the kidney 2x) located above the spine 1x. (Fig. 18) is removed by the kidney removal/washing rod 2h, and after the abdominal cavity is washed, the kidney is lifted up. That is, the lowering and raising of this rotary lever 1h is performed intermittently by adjusting the shape and rotational speed of the cam 12h, and with this rotation, the rod-shaped body for kidney removal and cleaning 2h, as mentioned above, the throat is positioned at a predetermined position regardless of the size of the fish, and the tip is aligned with the position of the throat of the fish being transported, and the tip is inserted from above the open abdomen to the kidney at the throat, regardless of the size of the fish. 112x, and maintains this downward state until the kidney 112x up to the anus is removed by transporting the fish body, regardless of the size of the fish body, and then rises. In addition, the tip of the rod-shaped body 2h for kidney removal and cleaning should be attached to the spine 1, which extends from the throat to the anus, regardless of the size of the fish.
In order to reach x, the cam groove of the cam 12h was formed deep and wide, and cam levers 11h were provided on both sides of the rotating lever 11h so that the tip of the rotating lever 1h could rotate downward as shown in FIG. When the tip of the cam lever 11h is loose in the cam groove, the springs 14h and 14h force the tip of the kidney removal and cleaning rod 2h to the spine lx for a long time and reliably. It is best to press them together. If you do this, the spring 14h.

By adjusting the biasing force 14h, it is possible to obtain an appropriate downward pressure for the kidney removal/washing rod 2h regardless of the size of the fish.

The kidney removal and cleaning rod 2h in the kidney removal device H includes a rod 3h having a water supply channel 31h, a nozzle portion 4h provided at the lower end of the rod 3h, and a nozzle portion 4h provided on the back surface of the nozzle portion 4h. It consists of a kidney removal plate 5h. The rod 3h is provided at the tip of the rotary lever 1h so that its lower part can be tilted toward the conveying direction of the conveying device C against the urging force, and the water supply channel 31h connects the hose 32h. It is connected to a washing water pressure pump (not shown) through the pipe. Further, the nozzle portion 4h has a bulged surface with a convex curved surface so that the excretion from the abdominal cavity can be easily and smoothly. Nozzle holes 41h, 41h, ...
are opened in a vertical line on the surface of the bulge. or,
The kidney removal plate 5h is made of a flexible material so as not to damage the abdominal cavity wall, and is fixed to the flat part on the back side of the nozzle part 4h by a restraining plate 54h. The lower end of the kidney removal plate 5h is the kidney 111i2x.
The nozzle part 4 has a shape that allows it to be scraped off.
It is located below the lower end of h. According to the kidney removal and cleaning rod-like body 2h configured in this way,
Since the rotating lever 1h is maintained in the downward rotating state as described above, as the fish is transported by the transporting device C, the kidney 2x is moved from the throat of the fish toward the anus without damaging the abdominal cavity. Scrape the kidney with a kidney removal plate 5h, and at the same time inject the inside of the abdominal cavity with nozzle holes 41h, 41h.

The high-pressure washing water sprayed from ... can wash the abdominal cavity without damaging it. Regardless of the size of the fish, the kidney removal and cleaning rod 2h is further tilted against the spring 52h by the vent near the anus of the fish being transported, before the rotating lever 1h is raised. Especially spine 1
Even the kidney which is difficult to remove in the vicinity of the anus where there is a large unevenness where x is raised can be removed by the kidney removal plate 5h by the guiding action of the convexly curved swelling part of the nozzle part 4h and removed from the abdomen into the indoor bath.

Although two kidney removal devices are provided, it goes without saying that there is no limit to the number of kidney removal devices.

Next, the processing of a fish body by the visceral cutting device of the present invention having the above-mentioned configuration will be explained based on the automatic processing of a fish body by the above-mentioned automatic processing device.In such automatic processing,
By simply feeding the fish body into the supply path 1b in an easy manner as described below, that is, by simply feeding the fish body with its abdomen facing upward and towards its head, the fish body can be kept in a well-positioned state regardless of its size. The fish bodies are automatically supplied to the transport device C, and are automatically and continuously processed while being transported.

That is, as described above, the size of the fish supplied to the supply path 1b with the abdomen facing upward and the head facing forward is detected by the guide levers 2b, 2b in the supply positioning device B, and the size of the fish is detected by the guide levers 2b, 2b of the supply positioning device B. The tip of the fish head is received by the fish head tip receiving plate 3b which rotates in the feeding direction as described above in response to the detection, and the throat of the fish is positioned at a predetermined position regardless of the size of the fish.

Regardless of the size of the fish, when the throat of the fish is positioned at a predetermined position in this manner, the brake of the stop lever 4b in the supply positioning device B is released in synchronization with the transport device C, as described above. As a result, the tip receiving plate 3b of the fish body curved portion is pushed open and the fish is fed to the starting end of the transport device C.

As described above, the fish fed to the transport device C is fed to a predetermined position, that is, with the abdomen facing upward and the head facing forward, the throat is positioned at a predetermined position regardless of the size of the fish. It is transported in a fixed manner.

The fish body is being transported while being positioned and fixed by the transport device C.
By passing under the semi-dress cutter, the semi-dress cutter cuts the fish from its throat to its anus, regardless of its size, as described above.

The fish body that has been cut into semi-dressed pieces during transport is transferred to the abdominal opening device E.
At the start of passage, as mentioned above, the abdominal opening levers 3e and 3a descend and open and close in time with the semi-dress cutting part of the fixed fish body, and hold only the abdominal cavity regardless of the size of the fish body. As a result, the abdomen is opened without the internal organs being scraped up, and the abdominal opening levers 3e and 3g, which move together with the transport device C, maintain this position thereafter.

In this way, the abdominal opening state of the fish is maintained by the abdominal opening levers 3e, 3e, and the fish is being transported by the transporting device C with the throat positioned and fixed at a predetermined position regardless of the size of the fish. At the time point A is reached, as mentioned above, the tip is devised so as not to cut the abdominal cavity wall, and at the same time as the fish is being transported, the tip is inserted from above the base of the stomach into the abdominal cavity regardless of the size of the fish. Regardless of the size of the fish, the covered rotary knife 4a, which descends until it touches the wall and immediately rises, cuts off the stomach without injuring the abdominal cavity and leaving a part of the base of the stomach pouch, regardless of the size of the fish.

Next, when the fish being transported in an open state with the base of the stomach pouch partially cut off reaches the viscera removal device F, the throat is positioned and fixed at a predetermined position regardless of the size of the fish, as described above. Regardless of the size of the fish, the clamping lever 21.21 lowers sufficiently from above the stomach pouch in time with the fish being transported, and then immediately rises, so that the stomach pouch is firmly clamped and connected to the stomach pouch, regardless of the size of the fish. Visceral organs other than the kidneys are removed from the abdominal cavity along with the WI# membrane.

In this way, by cutting the base of the stomach pouch and removing a portion of it, then grabbing the stomach pouch and removing the internal organs connected to it, damage to the ovaries can be reduced, and kidney removal and abdominal cavity cleaning can be easily performed. It can be implemented to

Next, when the fish body is being transported in an open state with the kidneys remaining, when it reaches the kidney epidermal cutting device G, the tip part is devised so as not to cut the abdominal cavity wall, and the fish body is cut as described above. Regardless of the size of the fish, the throat is positioned and fixed at a predetermined position, and in time with the fish being transported, the tip descends from above the throat until it comes into contact with the spine, regardless of the size of the fish, and this contact state is maintained during transport. Regardless of the size of the fish, the covered rotating knife 2g, which rises after maintaining the fish, completely cuts the epidermis of the kidney, making it easy to remove the kidney in the next step. .

After that, the fish body being transported in an open state with the epidermis of the kidney cut off, when it reaches the kidney removal devices H, H, moves smoothly along the spine regardless of the size of the fish body, as described above. The tip is designed so that it can smoothly escape from the anus position of the open abdomen, and the throat is positioned and fixed in a predetermined position regardless of the size of the fish. The rod-like body 2h for kidney removal and washing descends from above until the tip touches the spine regardless of the size of the fish body, maintains this contact state regardless of the size of the fish body being transported, and then rises to clean the fish body. Regardless of the size, the kidney is completely removed and the abdominal cavity is washed without damaging the abdominal cavity. In this case, if the epidermis of the kidney is not sufficiently cut in the previous step, it will be difficult to remove the kidney only by spraying high-pressure washing water.

The fish body, from which the kidneys have been removed and the abdominal cavity has been washed, is discharged from the transport device C and becomes a valuable semi-dressed product.

Although it is preferable that the internal organ cutting device of the present invention be incorporated into an automatic processing device as described above, it goes without saying that it can be used alone without being incorporated in this manner.

〔Effect of the invention〕

Like an ironworker, the fish visceral cutting device of the present invention can cut off the base of the stomach pouch leaving only a part of it, regardless of the size of the fish, without damaging the abdominal cavity. The subsequent post-processes, especially the visceral removal process, can be carried out easily, and this has a great effect that can contribute to the automation of the manufacturing process of semi-dressed products.
