DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a live fish tightening processing machine which is used for simply and efficiently processing (stabbing) live fish.

[0002]

2. Description of the Related Art When a large number of live fish are processed, if they are relatively large, such as bream, it takes time and effort to close the fish, so it is necessary to efficiently perform this process. .

[0003] For this reason, a simple processing apparatus in which a live fish is moved to a tightening place in a fixed posture in the past has been devised and used.

[0004]

The conventional processing apparatus described above cannot be used yet, for example, it cannot be used unless the size of the fish to be processed is substantially the same as that planned at the time of design. is there. SUMMARY OF THE INVENTION It is an object of the present invention to provide a live fish tightening processing machine which is more versatile than the conventional one, and which can perform the processing accurately and simply.

[0005]

In order to achieve the above object, in the present invention, a pair of endless belts are disposed so as to be opposed to each other so as to be accessible by elasticity, and a narrow fish forced conveying path is provided between the belts. And a fish size discriminating device is provided in the middle of this conveyance path, and the movement of the head of the fish conveyed to a certain position by the belt slightly ahead of the end of the forced fish conveyance path is temporarily determined. There is provided a position regulating device to be regulated, and further, a blade robot which operates so as to appropriately insert the blade into a specific portion of the fish in relation to the size information of the size identification device is provided.

At this time, the position control device is formed of a pair of plate members for holding the right and left heads of the fish from both sides and a support member for supporting the chin portion of the fish via a slope.

[0007]

In the fish forced conveyance path, the live fish supplied to the conveyance start end is pinched from both sides by a pair of endless belts and moved to the vicinity of the conveyance end. In connection with this movement, the position regulating device regulates and fixes the head of the fish in a fixed position, and then the knife robot pierces the vertebrae of the fish with the knife. Thereafter, the regulating operation of the position regulating device is released, and the endless belt sends out the processed fish further forward.

In the restricting operation state of the position restricting device, the pair of plate members and the support member fix the head of the fish at a precise fixed position.

A description will be given of an example of use of the product of the present invention configured as described above and its operation. An operator operates the control panel 30 to input information on the type of fish to be processed, the blade 29, and the like, and to operate each section. State.

Thereafter, the live fish are brought into a swimming posture and inserted horizontally between the belts 11a and 11b on the supply side of the fish forced conveyance path 14 from the head. The fish w thus supplied is pulled in by the pair of belts 11a and 11b which are in a circling state by the rotation of the driving rollers 7a and 7b, and is forcibly conveyed forward by the moving force of the belts 11a and 11b. At this time, since the pair of belts 11a and 11b are brought close to each other by air pressure, regardless of the thickness of the fish w, the fish w
The right and left sides are closely attached to each other to give an appropriate conveying force.

During the transportation of the fish by the forced fish transportation path 14,
As shown in FIG. 2, the back is in contact with the abutment plate 18, which is raised in accordance with the size of the fish w, so that the light-shielding plate 19 is also raised by a size corresponding to the amount of rise. The light shielding plate 19 raised in this manner is detected by a specific optical sensor of the detector 20. Therefore, the plurality of optical sensors of the detector 20 are in a detection operation state according to the size of the fish w. The state is determined by the control panel 30, and the size of the fish w is identified.

When the fish w in the transport path 14 reaches the vicinity of the position regulating device 21, the sensor 31 detects this and sends a detection signal to the control panel 30. It is stopped and the forced transportation of the fish s is stopped.

In connection with this, the position restricting device 21 performs the restricting operation, that is, the pair of plate members 22a and 22b which have been separated from each other are moved closer by the operation of the air cylinder 24, as shown in FIG. Sandwich the head of fish w
Subsequently, the support plate 23 at the evacuation position p indicated by the imaginary line is swung around the axis 26 by the operation of the encylinder 25, and the jaw portion of the fish s is supported on the slope s of the support member 23.

On the other hand, while the position regulating device 21 operates, the blade robot device 27 operates to move the blade 29 to a specific position in a specific posture based on the size information of the fish size identifying device 15. The cutting tool 29 is caused to protrude toward the head of the fish w whose position has been regulated by the regulating operation of the position regulating device 21. Thereby, the knife 29 is fish w
The vertebral part of the occipital region is accurately pierced, and the fish w instantly dies.

The blade 29 is immediately pulled out. In connection with this, each part of the position regulating device 21 returns to the unregulated state, and then the motor 4 is rotated again to rotate the belt 1.
1a and 11b move to transport the fish w further forward and drop it from the slope 2.

Thus, one set of processing ends.
Thereafter, this is repeated.

[0027]

According to the present invention constructed as described above, it is possible to carry out the tightening process accurately, irrespective of the size of the fish, and by only a simple manual operation of supplying the fish to a fixed position. It is.

According to the second aspect, the head of the fish can be mechanically and reliably fixed at a fixed position.
