BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish processing apparatus which cuts both sides of a fish body along its middle bone and separates it into a middle bone part and meat parts on both sides thereof. .

[0002]

2. Description of the Related Art Conventionally, when fish are processed and sold, a portion including a middle bone and a portion of fish meat attached to the middle bone, that is, a middle bone is removed from a fish body, and meat on both sides of the middle bone is removed. We take out only the parts, so-called three-piece processing, and put the meat parts in trays and put them out in stores. At this time, the method of processing the fish body is to place the fish body on a cutting board, cut off the head of the fish body with a kitchen knife by hand, insert the kitchen knife from the tail on one side while holding the fish by hand, and put the meat on one side Disconnect. Next, the fish body is turned over, a kitchen knife is inserted from the tail on the other side, the meat portion is cut off, two meat portions are taken out, and the middle bone portion is discarded.

[0003]

However, in the above-mentioned conventional method, since a fish knife is manually put into a kitchen knife and lowered into three pieces, it takes a lot of trouble and time to process a large amount of fish, and the cost is low. There was a problem that becomes high. Also, when processing a large amount of fish, many workers line up in front of the cutting board and process the fish on the cutting board, so there is a problem that a large processing plant is required and high equipment costs are required. . The present invention has been made in view of such circumstances, the processing of automatically lowering the fish to three pieces,
An object of the present invention is to provide a fish processing apparatus capable of processing a large amount of fish in a small space processing plant at a low cost.

As shown in FIG. 2, the cutting means 40 comprises two thin rotary blades 42 each having a saw blade 41 on the outer periphery, for example, having a thickness of about 0.1 mm and a diameter of about 25 to 100 mm. A pair of circular saw blades 43 are provided so as to partially overlap each other and arranged in the front-rear direction. The circular saw blade pair 43 is, for example, 2 to 2 around the lower discharge port 32.
They are arranged on the left and right with a gap of about 5 mm. The clearance on the outlet side of the inclined guide plate 35 is a circular saw blade pair 43.
It is desirable that the gap be substantially the same as the gap. The pair of circular saw blades 43 is driven to rotate by a rotation driving unit 50 including an air motor or an electric motor capable of rotating at a high speed of, for example, about 10,000 to 30,000 revolutions per minute. Each is rotated in the direction of winding inward. Therefore, as shown in FIG. 3, the front rotary blades 42 of both the left and right circular saw blade pairs 43 are driven in the same direction by the left rotary driving unit 50, and the rear rotary blade 42 is in the opposite direction to the front side. Is driven by the rotation driving means 50 on the right side.

Outside the lower portion of each pair of circular saw blades 43, there is provided a separating member 60 having a slide-shaped inclined surface extending obliquely downward from the side of the pair of circular saw blades 43 toward the outside. The middle bone portion 21 and the left and right meat portions 22 cut by the cutting are separated and dropped. Between the separating member 60 and the pair of circular saw blades 43, a resin gap crushing material 61 is provided. The gap crushing material 61 is made of resin such as vinyl chloride, ethylene tetrafluoride resin (trade name Teflon), nylon (trade name) resin, and the like, even when it comes into contact with the rotating pair of circular saw blades 43, for example. The pair of circular saw blades 43 is provided at an end portion of the separating member 60 facing the outer side surface of the pair of circular saw blades 43 so that the pair of circular saw blades 43 and the gap crushing material 61 are slightly in contact with each other or have almost no gap. Circular saw blade pair 43
A plate-shaped scattering prevention member 70 for preventing the outside of the middle bone portion 21 cut by the pair of circular saw blades 43 before and after the outside.
Is provided.

Here, the operation of the fish processing apparatus 10 according to one embodiment of the present invention will be described. The head of the fish body 20 is removed in advance in a separate process, and when the fish body 20 is thrown in from the inlet 31 of the guide hopper 30, the fish body is fed together with the water supplied into the cylindrical guide hopper 30 from the water supply unit 33. 20 is oriented vertically so that, for example, the tail portion 23 faces downward, it is slid and sent to the lower outlet 32.
The fish body 20 pushes and spreads the pair of inclined guide plates 35 against the springs 34 by its own weight and the flow of water, and the lower part 23 of the fish body 20 is discharged in a state where the tail 23 follows the flat exit of the inclined guide plate 35. It falls from the exit 32. Falling fish body 20
Are the saw blades 41 of the pair of circular saw blades 43 which are provided from the tail 23 and immediately below the lower discharge port 32 and rotate inward each other.
, And the rotary blade 42 is drawn downward by the rotation of the rotary blade 42 inwardly of each other.

The fish body 20 enters the gap between the two pairs of circular saw blades 43 arranged on the left and right from the tail portion 23, and is watered by the pair of circular saw blades 43 rotating on both sides of the middle bone portion 21 following the tail portion 23. In the folded state, it is smoothly cut in the longitudinal direction along the middle bone portion 21, and the middle bone portion 21 falls downward from the gap between the pair of circular saw blades 43. The meat portions 22 on both sides of the middle bone portion 21 are separated and taken out of the pair of circular saw blades 43, respectively. Therefore, when a plurality of fish bodies 20 are continuously put into the guide hopper 30, the fish bodies 20 dropped from the lower discharge port 32
Is automatically cut continuously by the pair of circular saw blades 43,
The middle bone portion 21 and the meat portion 22 are separated. Both meat parts 22

When the middle bone portion 21 falls downward from the gap between the left and right circular saw blade pairs 43, the middle bone portion 21 tends to fly outside the circular saw blade pair 43. However, since the plate-shaped scattering prevention members 70 are provided on the front and rear sides of the pair of circular saw blades 43, the middle bone portions 21 scatter on the front and rear sides of the pair of circular saw blades 43, and are placed on the separation member 60 and the products are separated. Mixed into the meat part 22
Contamination of the surroundings can be prevented.

The meat portion 22 is separated from the pair of circular saw blades 43 by the separating member 60. If there is a gap between the pair of circular saw blades 43 and the separating member 60, the gap of the meat portion 22 The portion may enter and bite, and the meat portion 22 may accumulate on the separation member 60 without falling down from the separation member 60. However, even if it comes into contact with the rotating pair of circular saw blades 43, the resin-made gap crushing material 61 that has little friction.
Is attached to the end of the separating member 60 facing the pair of circular saw blades 43, so that no gap is formed between the separating member 60 and the pair of circular saw blades 43. 2
2 can be prevented from accumulating, and the meat portion 22 can be smoothly sent to the next step. In the description of the operation of the fish processing apparatus according to the above-described embodiment, the case where the fish is cut from the tail has been described. However, a flat fish can be cut from the head.
