DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic processing apparatus for small fish, and more particularly to an automatic processing apparatus for automatically and continuously cutting and separating a head from a body of a fish such as a firefly, a holly, a haze, and a mullet. Available to

[0002]

2. Description of the Related Art Conventionally, the work of removing the head and internal organs of fish is
In manual work, the head was first cut off, and then the abdomen was cut open to remove internal organs. Alternatively, in mechanical work, move the cutter from top to bottom like a guillotine to cut off the head and remove the internal organs attached to the head, or from the base of the head to the end of the abdomen containing the internal organs It was cut diagonally and straight to remove most of the sarcasm. As a device used for the production, Japanese Patent Publication No. 4-656
No. 53, the fish head and internal organs removal device described in
There is a fish head and abdominal cavity resection device described in -15031.

[0003]

However, in the former device described in the above publication, the head and internal organs are cut off when the cutting speed of the cutter is high, and the spinal cord cannot be cut off when the cutting speed is low. The fish are coarse and the intermittent cutting process makes it impossible to treat fish continuously. Thus, the latter device has a problem in that the yield is very poor because it cuts not only the internal organs but also a large part of the abdominal sarcasm of fish whose head is larger than the body length.

Accordingly, it is an object of the present invention to remove the head and internal organs of fishes, especially small ones, without cutting off the stomach, and to continuously finish the cut surface of the head into an orderly cut, which can be easily performed even by an inexperienced person. It is intended to obtain a head and internal organs removal device.

[0005]

According to a first aspect of the present invention, there is provided a supply apparatus 1 for transporting and supplying a fish head a in a predetermined direction.
And a transport device 4 for rotating and transporting the fish body from a terminal end of the supply device 1 to a predetermined position, a cutting device 5 for cutting and separating the head a of the fish body on the transport device 4, and An automatic processing device for small fishes, comprising a discharge device 6 for discharging fish bodies from the transport device 4.

Further, the invention of claim 2 has a configuration of an automatic processing apparatus for small fish, in which the feeding device 1 is provided with a feeding device 2 for intermittently transferring one pitch at a constant timing.

Further, according to the invention of claim 3, when the fish is transferred from the supply device 1 to the transporting device 4, the positioning device 3 for automatically pushing in the cutting position while automatically positioning the cutting position of the fish is provided. The configuration of the processing device.

According to a fourth aspect of the present invention, there is provided an automatic transfer system for small fishes, wherein the transport device is provided with a transport device for rotating and transporting one pitch at a time in synchronization with the transport timing of the supply device. The configuration of the processing device.

Further, according to the invention of claim 5, a small cutting blade 29 is provided which presses the torso b of the fish body in synchronism with the stop timing of the transport device 4 and simultaneously cuts and separates the head a. The configuration of the automatic fish processing device is adopted.

[0010]

The automatic processing apparatus for fish according to the present invention is used as follows. That is, simply aligning the head a of the fish body in a certain direction and feeding the same into the supply device 1 allows a dress product to be obtained continuously automatically.

Further, since the feed speed can be freely changed, the speed can be adjusted in accordance with the feeding speed. However, if the feeding is not completed in time, no problem occurs in the processing step. The feeding speed of the supply device 1 can be further increased by a plurality of workers, and in that case, it is preferable that the supply device 1 be made long in advance.

Next, the positioning device 3 transfers the fish to the transfer device 4 while pushing out the head a of the fish that has been thrown into one fish from the supply device 1. At this time, since the pushing tool has a cushion, the inertia of the fish body is killed immediately before stopping at the cutting position, and the fish acts to stop at the accurate cutting position.

When the cutting blade 29 is pressed down on the rotating disk of the transfer device 4, the cutting device 5 slides the upper surface of the rotating disk from the center to the outer periphery. It works so as to separate the trunk part b without splitting it while being attached to the part a.

Since the cutting blade 29 has a structure in which the blade 30 and the notch 46 are appropriately combined, the cutting device 5 is used.
When the fish is depressed, the fish cuts only the spinal cord from the opercular gland to the base of the pectoral fin, and keeps the internal organs from being cut.

The transporting device 7 includes the transporting device 4.
Since the L-shaped partition piece fixed on the rotating disk is caught by the pulling action claw and the stop action piece, the transfer device 4
Rotate one pitch at a time, or stop exactly at the cutting position of the spinal cord.

The inserted L-shaped plate 37 includes a drive arm 40 and a stopper 42.
Stopped at the correct position.

[0040]

Since the present invention is configured as described above, it has the following effects. The supply device 1 does not need to align the cutting positions of the fish at the time of feeding the fish, so even an unskilled person can easily feed the fish. Moreover, by increasing the length of the supply device 1 so that a plurality of workers can input fish in parallel and increasing the speed of fish processing, it is possible to easily increase the processing capacity per time.

Further, since the cutting device 5 is a mechanism for pressing the fish body b, the fish body b is hardly damaged, and is highly valuable as a dress product.

Further, the cutting blade 29 cuts only the hard spinal cord of the fish body and does not cut the internal organs, but is separated from the torso b while being attached to the head a. In addition, a dress product with a high yield can be obtained.

Further, since the cutting blade portion 29 is symmetrical, there is no need to align the dorso-ventral direction of the fish, the mechanism of the apparatus is simplified, and there is no need to align the dorsal and ventral directions when the fish is inserted. Even inexperienced people can handle it.

Further, since the transporting and feeding device 7 can accurately determine the stop position of the transporting device 4, the cutting device 5 can precisely cut only the spinal cord.
