When the dressed fish body b reaches the conveyor belt drum 12, the holding belt 14 is released,
In addition, the interval between the protrusions of the belt naturally increases. In addition, when the holding belt 14 is separated from the fish body b, the fish body b acts to weaken the force held by the transport belt 11, so that the fish body b falls naturally to the discharge shooter 19.

Thus, the fish with a high yield, whose head and internal organs have been removed, are discharged from the discharge shooter 19 and have high value as a dress product.

[0037]

Since the present invention is configured as described above, it has the following effects. Since the transport device 1 does not need to align the cutting positions of the fish at the time of supplying the fish at all, even an inexperienced person can easily supply the fish, and by further increasing the length of the transport device 1, a plurality of workers can carry the fish in parallel. It is possible to supply. Further, since the processing speed can be controlled, the processing capability can be further increased by increasing the speed of fish processing.

The transport belt 11 and the holding belt 14
Is a mechanism that corrects not only the fish body but also the posture,
There is no need to arrange them in an accurate posture when feeding fish.

Further, the rotary blade 21 cuts from the back meat behind the fish head a to the hard spinal cord, and has a structure in which the internal organs are separated from the torso b while being attached to the head a without cutting.
There is no tearing in the cut, and the product value increases. Moreover,
Since the rotating blade 21 can change the inclination angle depending on the type of fish, the back meat having product value does not adhere to the head a side, and a dress product with a high yield can be obtained.

The separation device 5 and the separation notch 23
As a result, since the head is cut away from the spine to the spinal cord behind the head of the fish, the head is separated while the internal organs are attached to it, so that a dress product of excellent quality is obtained.
