DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish body which has been cut so that the cut surface of the fish body is exposed to the outside, regardless of the posture of the fish body, after the fish body has been pinched and cut while being transported. The present invention relates to a fish processing apparatus that guides a fish fillet.

[0002]

2. Description of the Related Art Conventionally, fish bodies, such as cod and horse mackerel, are cut and cut by a pair of conveyor belts and conveyed, and a single piece called a harass cutter provided in the middle of the conveyance path is used. The abdomen of the fish body is cut in a head-to-tail direction by a pair of rotary blades, and the internal organs in the abdominal cavity of the opened fish body are scraped off by a gutting pulley and provided downstream of the gutting pulley in the transport direction. By cutting both sides of the middle bone of the fish from which the internal organs have been removed by a pair of rotating blades in a craniocaudal direction, a residue portion including a middle bone, a tail fin, a dorsal fin and a spine, and two cuts on both sides thereof Is used.

[0003] This fish processing apparatus is also called a three-sheet grater and can continuously process a plurality of fish. The cuts obtained by such a fish processing apparatus fall on a flat chute provided below the end of each conveyor belt, and are supplied to another fish processing apparatus such as a subsequent peeling machine, and are fly-fed. And boiled food.

[0004]

In the above prior art,
The outer peripheral surface of each conveyor belt is formed on a wavy or rough surface where concave grooves and ridges extending in the width direction alternately in the circumferential direction are formed in order to prevent the sandwiched fish body from shifting or sliding down. Therefore, the fish body is nipped by each transport belt by a large frictional force during transport, even if a large force acts on the fish body in a direction opposite to the transport direction by the rotational force of the gut pulley and the rotary blade, The fish body is prevented from shifting between the transport belts. However, at the end portion of each conveyor belt, when the facing lining portions of the conveyor belts are separated from each other and the sandwiching state of the fish is released, the two cuts from which the residue portion has already been removed are: Since the transport belts are transported in close contact with each other by an adhesive force or a frictional force, a penetrating force is applied in a direction in which each transport belt opens, and supplied in a state of being thrown onto the chute, so to speak, on the chute. Frequently, it is mounted with the cut surface down and the skin up.
Therefore, the cuts are mounted on the chute and the transport conveyor connected to the chute with the cut surface facing downward and the skin facing upward. for that reason,
The operator manually turns the cut over so that the cut surface is directed upward and the epidermis is directed downward, and visually observes whether or not foreign matter such as bone fragments or scales is attached to all the cuts. Must be removed and the foreign material must be manually removed from the fillet to which it is attached. In order to save labor in the work of checking and removing such foreign matter, it is preferable to eliminate the above-mentioned reversal work.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a fish processing apparatus capable of improving the efficiency of the fish processing work by eliminating the manual reversal of the fish fillets.

[0006]

According to the present invention, there is provided a fish body in which a fish body is sandwiched from both sides in the thickness direction and is carried downstream in the carrying direction by a carrying means, and the fish body is cut in a head-to-tail direction along the carrying route. In the processing apparatus, at a terminal end on the downstream side in the transport direction of the transport unit, there is provided a fillet guide unit having a guide surface curved so that each cut surface of the fish body facing each other faces upward. It is a fish processing device. According to the present invention, the fish transported downstream in the transport direction is
It is nipped from both sides in the thickness direction by well-known conveying means such as each conveying belt or a conveying chain. The posture of the fish transported by such a transport means is such that the head is directed downstream in the transport direction, the tail is directed upstream in the transport direction, the back is upward, and the abdomen is downward, so to speak, the fish is head. When transporting fish with the tail direction horizontal, or in a so-called vertical fish processing device that transports fish from above to below, the fish is transported to the downstream side in the transport direction with the tail upward and the vicinity of the head downward. Therefore, the posture of the fish body in the present invention at the time of transport may be any posture regardless of whether it is up and down of the back and belly, and before and after the head and tail. The fish conveyed by the above-mentioned conveying means, both sides or one side of the middle bone are cut in the craniocaudal direction, and the cuts that have been cut or separated or opened without being separated are along the guide surface of the cut guide means. The posture is guided and the posture is changed so that the cut surface faces upward. By such a cut guide means, all cuts of a large number of fish continuously conveyed by the transfer means are surely opened without manual operation, and guided so that the cut face always faces upward. Therefore, the worker only needs to visually check the cut surface to check whether foreign matter such as bone fragments or scales is attached, and improve the efficiency of fish processing work. it can.

According to the present invention, the fillet guide means having a guide surface in which the contact portion on the back of the fish body is inclined more outward than the contact portion on the abdomen as the downstream side in the transport direction is provided, The fish cuts conveyed by the conveying means to the downstream side in the conveying direction can be always aligned with the cut surface facing out, and can be carried out. This eliminates the need to turn over the fish and improves the efficiency of fish processing.

Claims (1)

(57) [Claims] 1. A fish processing apparatus for sandwiching a fish body from both sides in a thickness direction of the fish body and transporting the fish body to a downstream side in a transport direction by a transport means, and cutting the fish body in a head-to-tail direction along the transport path. A fish body processing apparatus, characterized in that a cut piece guiding means having a guide surface which is curved so that each cut surface facing each other faces upward is provided at an end portion on the downstream side in the transport direction.
