Description

[Detailed Description of Device] a. Purpose of the Invention (Industrial Application Field) This invention relates to a device for manufacturing small fish, mainly eel opening.

(Prior Art) Conventionally, the opening of small fish is generally abdominal opening, and in particular, it is preferred that the shark has a shape in which the lips are left in a circular shape without being incised, and most of them are manually done with a kitchen knife.

However, in recent years, a machine-opening device has been developed, and its processed opening pearls are found in the market.However, the lips are cut open and the shape when dried is bad, so the commercial value of the product decreases, and consumers especially cooked food. Demand at shops and inns does not grow.

(Problems to be solved by the invention) Therefore, even if the object of the invention is a mechanical opening device, the lips of the small fish having a body length of about 10 to 25 cm are not opened but left in a circular shape, and the body is completely removed. It is necessary to make a deep cut so that it can be opened.

B. Configuration of the Invention (Means for Solving the Problems) In order to achieve the above-mentioned object, the invention is a pair of holding type conveyors for holding a fish body from both sides on a fish body supporting member composed of a horizontal guide plate member or a belt conveyor. In the device equipped with a single rotating disc cutter for opening inserted between the pair of holding type conveyors, the pair of holding type conveyors is provided with an uneven shape with ridges in the vertical direction. An L-shaped bent fish pushing-up member is provided immediately below the rotary disc cutter, and the bent portion has a concave upper portion, and the fish frame pushing member is attached to the machine frame or a supporting member mounted on the machine frame. It is equipped with a shaft that is tiltable at right angles to the carrying direction of the sandwich type conveyor and can be tilted, and in the normal position, one piece of the L-shaped bent fish pushing-up member on the unloading side is immediately carried by the rotary disk cutter. At the position where the fish passes, the standing piece stands up, the other piece becomes substantially flush with the fish body supporting member, and when the fish passes, the standing piece on the carry-out side of the fish body pushing-up member falls in the carry-out direction, and the other piece rotates. The opening device for small fish is characterized in that it is elastically biased so as to stand up within a range where it does not come into contact with the disc cutter.

In order to achieve the above-mentioned object, the end surface of the carry-in side piece of the fish pushing-up member of the small fish opening device of the present invention is V-shaped.
It may be characterized in that a V-shaped guide groove is engraved.

In order to achieve the above object, the rotary disk cutter of the small fish opening device of the present invention is a first rotary disk cutter, and the cutting edge angle is 35 ° to 45 °.
At least two second cutters are sequentially installed in series between the pair of holding type conveyors on the upstream side of the rotary disk cutter, and the tip angle of the second rotary disk cutter is sharper than that of the rotary disk cutter. It is preferable that the rotary disk cutter on the upstream side has a sharp edge angle.

(Operation of the Invention) In the present invention configured as described above, a large number of small fish of approximately the same size are prepared, and the device of the present invention is operated to place the belly of the small fish in contact with the upper surface of the fish body supporting member. Feed one by one between the holding type conveyors with the head on top and the head first, and adjust the cutting depth of the rotary disc cutter to the depth of the lips without cutting the lips.

By doing so, the small fish are incised from the ventral side of the head of the small fish to the lips by the rotary disc cutter, and then the lip portion passes through the rotary disc cutter portion, and the unloading side of the standing fish body pushing-up member. Since the fish hits one piece and is conveyed further downstream by the pair of sandwich type conveyors of the fish body, the fish body pushing member rotates forward about its shaft, and the carry-in side piece lying horizontally on the carry-in side. Starts to stand up, and the head part of the whole fish body is slipped and lifted along the direction of the uneven ridges of the pair of holding type conveyors, and the rotary disk cutter is cut deeply into the fish body by that amount.

Thus, the fish body is incised from the base of the head to the trunk to a position close to the spine, and is carried out from the pair of sandwich type conveyors, and the portion near the tail does not change its vertical position, and the fish body pushing-up member. Is guided to the end surface of the carrying-in side piece and cut to the vicinity of the dorsal fin by the rotary disk cutter, and finally the fish body is sent out from the carrying-out end of the pair of holding type conveyors. When the fish passes, the fish pushing-up member returns to its original position by the restoring force of the tension spring, and when the next fish passes, the same action is repeated.

According to the second aspect of the invention, when the fish body pushing-up member is tilted, the center of the fish body is guided to the center between the pair of holding type conveyors by the groove of the end surface of the upstream side piece, and the tail portion is accurately reached. It is opened by a rotating disk cutter.

According to the third aspect of the invention,
When the cutting depth of the rotary disk cutter is sequentially shallower than that of the rotary disk cutter on the downstream side, and the fish bodies are sequentially supplied between the pair of holding type conveyors, the fish bodies are divided into the second and the first.
Each time it passes through each rotating disk cutter, it is gradually cut deeper and opens.
