DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An outline of the structure of a back-and-bellied fish aligning apparatus according to the present invention will be described with reference to FIGS. FIG. 1 is a top view of the spine alignment device for fish, FIG. 2 is a front view, and FIG. 3 is a right side view of the spine alignment portion.

The apparatus 1 for aligning the head of a fish body and sending the fish F in two directions by aligning the head of the body F, and receiving the fish F sent from the head direction aligning section 3 to adjust the spine of the fish body. It comprises a rear-to-back direction aligning unit 5 to be aligned, and a transport unit 7 for transporting the fish body F sent from the rear-to-back direction alignment unit 5 and aligned.

The head-direction aligning section 3 is composed of a reciprocating rotary table 31 into which the fish is put, and an outer guide 32 and an inner guide 33 for guiding the movement of the fish.

The back-to-back direction aligning section 5 includes a polygonal roller 51.
, A cylindrical brush 52, and an outlet chute 53, and two sets are provided corresponding to the outlets of the head direction aligning section 3.

The transport section 7 is an apparatus for transporting the fish F to the fish processing apparatus, and includes a plate conveyor 71 and the like.

On the upper surface of the reciprocating rotary table 31, fine concave and convex portions like the surface of a rough top belt and fine grooves radially provided from the center of the circle to the outer periphery are formed. The reciprocating rotary table 31 rotates and reciprocates around a rotating shaft 34 driven by driving means such as a motor (not shown) fixed to the lower surface. Outer circumference guide 32
Is provided in the shape of a circular wall surrounding the periphery of the reciprocating rotary table 31 and has an outlet partially extending toward the back-to-back direction aligning portion 5. The inner peripheral guide 33 is provided in a U-shaped wall shape disposed on the center side of the reciprocating rotary table 31, and extends toward the dorsal and abdominal direction alignment portion 5.

The polygonal roller 51 has a polygonal shape composed of a fish catching portion 511 composed of linear vertices extending in the direction of the rotation axis, and a portion 512 having a small frictional resistance composed of a flat portion formed between adjacent vertices. It is configured as a rotating roller. The polygonal roller 51 has an octagonal prism shape made of, for example, polyethylene, and has a diameter of 100 mm and a height of 100 mm, for example.

The rotating brush 52 is provided with a brush made of, for example, a fiber made of nylon having a long hair length of 0.5 mm and a length of 40 mm, and has a height of 100 m.
m, having an outer diameter of 100 mm, and is rotated by a rotating shaft 55. The polygonal roller 51 and the cylindrical brush 52 are arranged to face each other at an interval slightly smaller than the minimum width of the fish to be processed, and rotate in opposite directions so that the fish are sandwiched in the dorso-ventral direction and sent to the transport unit 7 side.

The plate conveyor 71 is an ordinary plate conveyor used in a fish processing apparatus.

The operation of the fish aligning apparatus having such a configuration will be described with reference to FIG. First, the fish body F thrown into the head direction aligning unit 3 from the left side of the figure is placed on the reciprocating circular table 31 that rotates and reciprocates. It is sent and distributed in the head direction by the friction different depending on the direction of the fin and the fin, and the head is aligned and discharged to the upper and lower outlets in the figure, and the outer peripheral guide 32 and the inner peripheral guide 33
Is supplied to the dorsal and ventral direction aligning section 5 one by one. That is, the fish body F is sent to the dorsal and abdominal direction aligning section 5 along the outer circumference guide 32 with the head side first.

The polygonal roller 51 and the long-haired cylindrical rotary brush 52 of the dorsal-ventral alignment unit 5 rotate at about 300 revolutions / minute, respectively, and have an interval slightly smaller than the minimum width of the fish to be processed. , And can be taken in without adjusting the interval according to the fish and without damaging the fish irrespective of the freshness and thawing state of the raw material.

In the back-to-back direction alignment unit 5, the back-to-back direction of the fish is aligned according to the principle described later,
Is discharged.

The fish discharged to the transport section 7 is placed on the plate conveyor 71 and transported in the same direction of the head and the dorso-ventral as shown in the figure.

FIG. 5 shows the back-to-belly alignment operation in the back-to-belly alignment unit 5.
This will be described with reference to FIG. FIGS. 5A to 5F are diagrams for explaining the relationship between the fish body and the polygonal roller 51 and the cylindrical rotary brush 52 in the dorsal and abdominal direction aligning section 5 in time sequence. The bottom view is the view seen from the discharge direction.

The fish F sent from the head alignment unit 3 to the dorso-ventral alignment unit 5 with the head at the head hits the polygonal roller 51 and the cylindrical rotary brush 52 (FIG. 5).
(A)).

When the head of the fish F is drawn between the fish catching portion (corner) 511, which is a linear vertex extending in the direction of the rotation axis of the polygonal roller 51, and the cylindrical rotary brush 52, the spine of the fish returns. Regardless of which side of the belly is facing left or right, the cross section of the fish body and the action of the cylindrical rotary brush 52 always stand up with the belly side down and the back side up (FIG. 5B).

Further, when the polygonal roller 51 and the cylindrical rotary brush 52 continue to rotate and draw in the fish F, the cylindrical rotary brush 52 presses the fish against the polygonal roller 51,
Due to the cross-sectional shape of the fish body whose abdomen is narrow, the back side of the fish body is inclined toward the rotating brush 52 (FIG. 5C). Sardine saury
The cross section of small fish such as mackerel is thicker on the dorsal side than on the ventral side,
The fish body always leans to the brush side.

When the fish F comes into contact with the flat portion 512 having a small frictional resistance formed between the polygonal roller 51 and the adjacent vertices, the frictional resistance between the fish F and the flat portion 512 is reduced, and the rotation is reduced. By the driving force of the brush 52, the fish body is vigorously sent out to the outlet chute 53 (FIG. 5D).

Since the back side of the fish body F is already inclined to the rotating brush 52 side, all the fish body F sent out comes out with its back toward the cylindrical rotating brush 52 side (FIG. (E)).

In the above description, the rotary roller 51 is a polygonal roller. However, when the rotary roller 51 disposed opposite to the cylindrical rotary brush 52 has a cylindrical shape, the frictional resistance of the surface is constant. There is a possibility that the speed at which the fish is sent out is low and the direction of the back and belly is reversed. However, when the shape of the rotating roller 51 is a polygon (for example, an octagon) as in the present invention, as shown in FIG. 5D, the flat portion 512 of the rotating roller 51 and the cylindrical rotating brush 52 are formed. Due to the difference in frictional resistance, the fish body F is sent vigorously while being tilted, and at the exit, the belly always comes out toward the cylindrical rotary roller 52 side.

Actually, the success rate of the fish fed into the back-to-back alignment device was measured. When the cylindrical rotary brush 52 and the octagonal rotary roller 51 were used, 100% of the success rate was obtained. Success rate was obtained. However, the cylindrical rotary brush 52 and the square rotary roller 51
When (1) was used, the uptake of fish F shown in FIGS. 5 (A) and (B) was poor, and the success rate was reduced. On the other hand, when the cylindrical rotary brush 52 and the rotary roller 51 were combined with a cylindrical roller, the slippage was poor and the success rate was about 60%.

In the above description, an example was described in which a reciprocating rotary table was used as the head direction aligning unit. For example, a fish aligning and projecting device disclosed in Japanese Utility Model Laid-Open Publication No. 1-38744,
A left-right vibration type head alignment device such as a fish head tip turning device disclosed in Japanese Utility Model Laid-Open No. 6-23476 can be used. In this case, the dorsal and abdominal direction aligning portions may be provided on the respective fish body sending mouth sides.

[0031]

According to the present invention, the polygonal rotary roller 51 and the cylindrical rotary brush 52 are rotated in about 300 rotations (per minute), respectively, in directions opposite to each other (the side to guide to the outlet). It is rotating, and its interval is set slightly smaller than the minimum width of the fish to be processed, so that unlike the conventional device, without adjusting the interval according to the fish, and aligning the back and belly Fish F can be sent out.

Further, since the interval between the rotating rollers is not adjusted by using a spring or the like, there is no danger of damaging the fish depending on the freshness and thawing state of the raw material.
