Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a device for efficiently and labor-savingly extracting the so-called pin bones attached to the backbone of fish such as salmon, with the fish flesh still attached. be.

[Conventional technology]

Conventionally, when processing fish such as salmon to make a processed food such as smoked salmon, the pin bones exposed to the outside of the fish meat, which is cut into three pieces during the processing process, are removed by an operator using tweezers. I grabbed the books one by one and pulled them out.

[Problem that the invention aims to solve] Normally, salmon have around 50 pin bones attached to their dorsal side along their spine, but there are at least 25 pin bones that actually need to be removed. However, it took a considerable amount of effort to remove all the pin bones with tweezers.

In other words, the base of the pin bone is attached to the fish body, so if you continue to pull it out with tweezers, you will need both the force to grip the bone and the force to pull it out at the same time, which may cause your hands to hurt or cause injury to people. Sometimes I even developed tendonitis.

SUMMARY OF THE INVENTION In view of the above-mentioned problems that occur in the conventional pinbone extraction operation using tweezers, the present invention aims to provide an apparatus for efficiently extracting pinbones from fish.

[Means to solve the problem]

The configuration of the present invention, which was made to solve the above problems, is that two clamping pieces each having a claw-shaped tip are attached to the front end side of a vertically elongated cylindrical grip part so as to be openable and closable. A switch operated via an operating lever is attached to the side of the rear end of the gripping part, and by operating the lever, the gripping piece is closed with compressed gas supplied from the rear end of the gripping part. It is characterized in that the pin bone is held and removed.

[Effect]

The gripping piece in the device of the present invention has an appropriate width and is forcibly opened and closed by compressed gas, so the claw at the tip can easily and quickly pin-bone the fish.
Moreover, it can be gripped securely and firmly.

As described above, the pin bone extraction device A, which is an example of the present invention, is formed by 1 to 8. Next, the operation mode thereof will be explained.

The pin bone extraction operator lightly grasps the grip part 1 with one hand, places the opened grip pieces 3, 3 in a position where the claws 3a, 3a at the tips can grip the tip side of the fish's pin bone, and then operates the operating lever 7. When it is closed, the pressure switch 6 is activated and the compressed gas that is constantly supplied to the supply pipe 5 is supplied to the air cylinder in the grip part 1, which activates the rod and the link and the gripping pieces 3, 3 are moved. When it is closed, the claws 3a, 3a strongly pinch the tip of the pin bone.

In this state, if the operator moves back the extraction device A of the present invention, the pinbone can be easily extracted from the spine and body.

Since the extraction device A of the present invention is as described above,
This device A is one of the commercially available air tools.
For example, by modifying the cutting blade portion of the air nipper into a clamping piece 3 having a claw portion 3a, it can be formed at low cost.

FIG. 3 shows another example of the device of the present invention, which is equipped with a plurality of the above-mentioned pin bone extraction devices A, and is capable of distributing and supplying compressed gas to each of these devices A. This will be explained next.
