Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to a large number of fish fed onto a conveyor, and is used to transport fish whose dorsal and ventral sides are oriented in a direction different from that of other fish. The present invention relates to a dorsal-ventral inversion method and device for inverting a fish body in the correct direction.

Conventional configuration and its problems When processing fish bodies, it is necessary to feed a large number of fish bodies to the oscillator with their heads facing forward, and also to feed the heads with their dorsal and ventral directions facing the same direction. By automatically supplying fish to a fillet machine through cutting and viscera removal processing, it is being developed to enable complete automation from the supply of fish to predetermined processing.

In such a device, although it is possible to direct the heads of all the fish in the same direction using the oscillator, it is difficult to align their dorsal and ventral directions in the same direction.

For this reason, the inventors of the present application
1' As described in Publication No. 0, by moving the longitudinal center of the fish body in sliding contact with the ridge corner of a separator having a triangular cross section, the back or abdomen can be placed in the same direction on both sides of the separator. We have developed a device that allows the object to fall while pointing towards the enemy.

However, according to this device, although it is possible to make the postures of about 9g% of fish bodies the same, there are a few fish bodies with bad postures.
If this is fed as it is to the fillet machine side, the back will be facing downward and processing will be impossible. Therefore, the current situation is that fish in such bad postures have been manually removed from the conveyor while they are being transported by the conveyor. This is a major barrier to smooth efficiency.

Purpose of the Invention The present invention is intended to solve the above-mentioned problems, and is intended to solve the problem of fish bodies being sent by a conveyor with their heads facing in a certain direction, but with the dorsal and ventral direction facing in a different direction from other fish bodies. The present invention provides a dorsal-ventral reversal method for a fish body, which detects the posture of the fish body, and automatically changes the posture to the correct posture during transportation, and a device therefor.

Structure of the Invention In order to achieve the above object, the present invention comprises: a detection device for discriminating and detecting the dorsoventral direction of a fish body in close proximity to a conveyor; and a reversing mechanism having a protrusion body activated by detection by the detection device. are arranged in sequence, and when a fish in an incorrect posture that has been detected by the detection device reaches the reversing mechanism, the protrusions are made to protrude in a direction crossing the direction of transport of the fish.

The fish body (at) in the incorrect posture is conveyed downward along the drive sprocket wheel (2) and comes into contact with the front surface of the fish body (at), and its tip slightly pierces the end (FIG. 7).

This protrusion body (b) protrudes in a direction opposite to the fish body transport direction and diagonally intersects with the transport direction, and the fish body (a)
The center of gravity of the fish body (-) rotates in the mounting tray (4) as the fish body moves (downward movement), centering on the puncture point (fathom), and )
is flipped downward and assumes a normal posture.

This reversal time is a short time (usually about 0,2 seconds) until the nine mounting plates (4) move within l pitch, that is, reach the position of the mounting plate (4) adjacent to the front. The protrusion time of the protrusion body (19) is also the same, and the magnet switch α → is de-energized between the capes and returns to its original position by the force of the spring @υ ◎ The fish body thus assumes its normal posture. (=) is the guide plate (
6) The fish is sent downward along the inner surface of its lower periphery, and, like the fish in its normal position from the beginning, it leaves the mounting plate (4) and enters the chute) with its abdomen (0) facing downward. This is what is fed onto the conveyor (■) of the fillet machine (■).

In addition, in the above embodiment, the fish body reversal mechanism (t)
was arranged at the position of the semicircularly curved guide plate (6), and the fish's own weight was also utilized to perform the reversal.
The present invention is not limited to this, and the present invention is not limited thereto, and the present invention can be arranged above the transport conveyor (5) at a suitable location, and follow the movement of the fish body around the piercing point of the protrusion body. , the fish body can be turned over.

Effects of the Invention As described above, according to the present invention, when a fish body is being transported by a conveyor, a fish body in an incorrect posture with its dorsoventral direction opposite to that of other fish bodies is detected, and the reversing mechanism is activated. By activating the fish body, the dorsoventral direction can be automatically reversed to the correct posture, and this action can be performed instantly and accurately, allowing fish bodies with incorrect postures to be removed manually. It is possible to place all fish bodies in the correct posture on each fish body tray on the transport conveyor without removing the fish bodies, and therefore it is possible to fully automate the process from supplying fish bodies to the filleting machine and further processing thereafter. At the same time, the processing capacity can be improved.
