Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for aligning randomly thrown fish bodies with their heads at the top.

Conventional devices of this type are, for example,
As disclosed in Publication No. 110999, a rocking plate that swings back and forth in the left-right direction and a frame body that aligns the head-to-tail direction of fish bodies are provided above the rocking plate, and fish bodies that are randomly introduced are placed in a frame. By passing the body through it, the cranio-caudal direction is aligned, and then by swinging on the rocking plate, those whose heads are facing right will move to the right, those whose heads are facing left will move to the left, and the left and right sides will be moved separately. The fish were then guided to the fish processing equipment provided for processing.

An object of the present invention is to provide a fish head alignment device with a simple structure that allows the randomly thrown fish bodies to advance along the circumferential direction toward the head and takes them out from an arbitrary direction.

FIG. 1 shows a plan view of an embodiment of the present invention, and FIG.
The figure shows a cross-sectional view.

A substantially arcuate side wall 2 is placed on a substantially semicircular fish body mounting table 1.
A, 2B, and 2C are provided concentrically, and arcuate strips 3A, 3B are formed inside each side wall. Both ends 4A, 4B of each of these strip-shaped parts 3A, 3B
The angle formed by 5A and 5B is 180° and each is open, and below the belt conveyor 6 for carrying out runs in the direction of the arrow, and a guide fence 7 for maintaining the orientation of the fish on the belt conveyor. are placed in parallel.

Further, in the center of the fish body mounting table 1, there is provided a belt conveyor 13 for loading fish bodies from above.

A vertical shaft 8 is located approximately at the center of the concentric side wall of the fish mounting table 1, and the shaft 8 is driven to swing by a motor 9 via a crank mechanism 10. Rollers 12, 12 supported by radial shafts are disposed at appropriate positions on the base 11, and the fish body mounting table 1 is placed on these rollers 12, 12. Further, a rubber plate 1 having an uneven surface is provided on the top surface of the fish body mounting table 1 and the inner surface of the arc-shaped side walls 2A, 2B.
8 is attached.

Next, the action will be explained. The fish body mounting table 1 is connected to the motor 9
Fish bodies are randomly placed onto the fish loading table from the carry-in conveyor 13 while the fish bodies are being swung. When introduced, a fish whose head is in the direction of arrow A will move along the side wall in the direction of arrow A, and a fish whose head is in the direction of arrow B will move along the side wall in the direction of arrow B.
Proceed with your head in the direction of. The reason why the fish moves with its head first is due to the interaction between the uneven rubber plate 18 provided on the top surface of the mounting table and the inner surface of the side wall, and the scales of the fish. This is because the resistance is small, and even if you try to move in the opposite direction, the resistance of the scales is large. Furthermore, a fish body whose head-to-tail direction is radial when introduced is always swung in either direction A or B due to the rocking. This is because the force acting on the head of the fish is greater than the tail, and the head tilts in the direction of the first half-cycle of rocking when the fish is introduced. In this way, the fish advances along the arcuate side wall, falls onto the belt conveyor 6 from both ends, and is conveyed on the belt conveyor with the fish head at the top.

As another embodiment of the present invention, an arcuate fish-mounting platform of about 180 degrees is installed at a high position, and spiral-shaped slides that gradually descend are attached to both ends of the platform, and both the fish-mounting platform and the slide are connected to a single platform. By reciprocating the angle around the axis, the angle formed by both ends of the arcuate strip is set to be 360° or more, preferably an integral multiple of 360° or more, and various fish processing devices are installed on the way the fish descend the slide. The present invention can be practiced as follows. According to such an embodiment, it is possible to obtain a fish processing machine with a small installation floor area.

As is clear from the above description, according to the present invention, it is possible to take out randomly placed fish with their heads aligned in the same direction by using an extremely simple structure of swinging the fish body mounting table.
