DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for a frozen fish body which performs a laparotomy process, a filleting process and the like without completely thawing the frozen fish body.

[0002]

2. Description of the Related Art Heretofore, in order to process fish into three pieces, first, the head is cut, an abdominal laparotomy is performed, and after removing internal organs, a filleting process is performed. As such a processing device, for example, a pair of left and right fish transport belts that transport the fish while holding the fish with the cut head thereof facing the transport direction, and a fixed interval along the transport belt during the transport. There is generally known a filleting machine including a circular laparotomy cutter, a viscera removing means, a fillet knife, and a separate knife which are sequentially disposed for each case.

[0003]

However, when the frozen fish is directly supplied to the above-mentioned processing apparatus, the fish meat is hardened by freezing and the surface is smoothed and slippery. When performing laparotomy processing, the cutting resistance is large and the resistance overcomes the pinching force of the transport belt, and the fish body is pushed upward while slipping on the pinching surface of the transport belt or deflected backward to accurately perform the laparotomy process. Cannot be performed. Such a problem also occurs at the time of removing internal organs or filling processing. Therefore, it becomes difficult to treat the frozen fish with the processing apparatus as described above, and the above-described treatment must be performed after the fish have been completely thawed, which is troublesome and affects the meat quality of the fish. there were.

[0004] On the other hand, if pins are projected from the opposite surface of the conveyor belt at small intervals, and the pins are conveyed while piercing both sides of the frozen fish body, the fish body is firmly fixed by the pins. It is fixed, and it is possible to reliably process in a state where a predetermined posture is maintained without causing a slip even during processing with the above-described open-cut cutter or the like, but if the fish body is divided into left and right fillets by a separator knife after fillet processing. However, since each fillet remains in a state of being pierced by the pin, these fillets must be separated from the transport belt, and the processing is extremely difficult. In addition, since the pin pierces the most noticeable meat portion of the fish, there is a problem that the commercial value is significantly reduced.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a frozen fish processing apparatus capable of processing frozen fish reliably and efficiently without lowering its commercial value. It is in.

In this state, the piercing of the frozen fish body with the lower knife is performed to sequentially perform the laparotomy process, the internal organs removing process by the internal organs removing member, and the filleting process by the fillet knife.

[0008]

The frozen fish body is conveyed forward with the back portion facing upward and the cutting head side facing the conveying direction, while holding the frozen fish body by the conveying belt. When the frozen fish reaches the lower knife disposed on the way of transport, the pin of the transfer means disposed above the lower knife pierces the back of the frozen fish, and the pin moves in the same direction and at the same speed as the transport belt. Then, the frozen fish body is passed along the lower knife while firmly maintaining the frozen fish body on the predetermined conveying path together with the conveyor belt, and the frozen fish body is pressed against the lower knife by the transfer means at the time of passing the frozen fish body without delusion of the frozen fish body. Cuts the abdomen of the frozen fish precisely.

Next, the opened frozen fish bodies are sequentially sent to processing means such as a viscera removing member and a fillet knife by a transport belt.
In the same manner as described above, the internal organs removing process and the filleting process are reliably performed in a state in which the pin of the transfer means pierced into the back portion maintains a constant posture without slipping to the holding surface of the transport belt. After the fillet processing, the pins of the transfer means move upward and are pulled out from the back of the frozen fish, and the frozen fish are separated into left and right fillets by the front separator knife while being sandwiched by the transport belt, and separated from the transport belt. I do.
