2. Description of the Related Art Carp obtained by inland water fishing and inland water culture fishery is eaten by simmering bones and sliced slices of liver, but when it is cooked in large quantities at fishery processing plants, etc. In the process of processing the fillet, not only the fish body including hard parts such as scales and spine must be trimmed to the same size regardless of the fish shape, it is not only quick and Processing technology that safely processes large quantities is required. This carrot cutting work is a tough task for cooks due to the large size of the fish.It requires not only cooking techniques but also considerable physical strength, and concentrates nerves to make vivid cuts. In order to ensure that there is no shortage of processing or accidents due to long-term work, it is essential to secure sufficient personnel as a cooking worker. Not only is the population aging, but also because the number of young and middle-aged people who are cooking is decreasing, it is extremely difficult to secure the number of skilled cooks in line with the heyday of shipment. Therefore, establishment of a new marine processing technology that can solve such a situation is an important issue.

[0003] Such a problem is not limited to only one carp, but is common to all large fish such as salmon, trout, and bonito, and the fish body becomes curved and narrow from the middle of the trunk to the caudal fin side. Because of the shape of the fish, if the body and caudal fin are cut at the same interval, the cuts will not be aligned properly, which not only reduces the commercial value, but also the caudal fin Unlike the roasting of the torso, there is a problem that the fleshy part is hidden and the appearance is bad when serving dishes, so in addition to the work of changing the interval according to the fish shape , Requires a special processing technique of cutting obliquely on the side of the caudal fin, and furthermore, when cooking the simmered carp, it is necessary to cut the bones, scales, liver, etc. at once with the fish, Advanced cooking techniques In both cases, high-performance knifes and other cooking utensils must be prepared, and it is quite difficult to turn those operations into humans and try to mechanize them. In fact, there is almost no proposal for a typical mechanical device.

The present invention has been made in view of the above situation,
Judging whether it is not feasible to realize a practical mechanical device for improving the efficiency and safety of cooking fish, especially large fish, we started developing and researching it quickly and conducted trial and error for a long time. As a result of repeating many prototypes and experiments, this time, we finally succeeded in realizing a new fish round slice direction and a new fish round slice device used for it. The structure will be described in detail together with the embodiment shown in FIG.

A plurality of fish support bases which are arranged in parallel while securing the insertion portion for the cutting blade portion are provided,
The cutting blade portion was combined with the fish support base as a group directed in a predetermined direction at a predetermined interval capable of being inserted into all or some of the insertion portions from above or from the side. Above, the fish support table is provided with a moving mechanism that can move to the cutting blade side, and at least the cutting blade section is inserted into the insertion portion of the fish support table up to a predetermined position where the fish body can be sliced and cut at any time. The invention further includes a fish roasting device having a gist of the present invention.

Similarly, the fish body has a concave-shaped fish receiving surface which can be supported in the form of a support by shifting the fish body at least from the middle of the trunk to the side of the caudal fin. In addition, a plurality of fish support bases arranged in parallel while securing an insertion portion for the cutting blade part of a predetermined gap are provided between each other, and the cutting blade part is located above the fish support base. Alternatively, all of the insertion portions from the side, or combined as a group of a certain direction at a predetermined interval that can be inserted into some selected ones, and the cutting blade portion can be moved to the fish body support stand side A fish rotatable device having a cutting mechanism formed so that at least a cutting blade portion is inserted into a predetermined position at which the fish body can be rotatable and cut at any time into the insertion portion of the fish support base is also included.

The fish supporter has a function of supporting the fish in a desired posture, and secures an insertion portion having a predetermined gap into which the cutting blade is inserted to a position where the supported fish can be cut. It should have a fish receiving surface that securely holds the fish in the desired posture, and a fish cross section with its head cut off is brought into contact with the head of the fish so that the fish in the body length direction It is desirable to provide a positioning portion for positioning of, or to have a height adjustment mechanism to adjust the height of the fish receiving surface, and, if necessary,
It is extremely convenient to provide a holding mechanism for holding down the fish placed on the fish receiving surface from above and temporarily fixing it.

[0014] Further, the fish supporter may have a structure in which the distance between adjacent fish receiving surfaces can be changed as appropriate so that the size of the fish in the full length direction can be adjusted according to the length of the fish. In addition to the structure divided from the central part in the width direction, it can be configured to be able to change and adjust the interval according to the width of the fish, in addition to being able to hold and sandwich the fish, cutting the fish In the middle, the fish body is kept in a temporary fixed state continuously, and after cutting is completed, the cut fish body is dropped on the table arranged below,
It is also possible to add a configuration capable of being detached.

The fish receiving surface forms a part of the structure of the above-described fish support, and has a function of holding the fish to be sliced so as not to hinder the insertion of the cutting blade portion. It should be a structure that can securely hold each part of the fish body during the cutting of the fish body by the part, and it is desirable to have a concave longitudinal section formed according to the fish size, It is also possible to hold the fish body so that the back or abdomen is directed upward, or to hold the abdomen and back in a horizontal direction.

Not even.

The insertion portion for the cutting blade portion is formed with a small space between the fish support bases so as not to hinder the access of the cutting blade portion, and is held on the fish support base. To a position where the fish body can be completely cut, the function of enabling the movement of the cutting blade portion is achieved, and a predetermined gap that is formed in parallel between a plurality of fish body support bases is provided. Even when the cutting blade part rotates or reciprocates and passes, it must be set to a distance that does not contact the fish support base, and when the cutting blade part finishes cutting and moves backward However, the gap should be designed so that the cut fish cut does not accidentally fall into the gap, and basically, it should be set to be somewhat narrower than the cut to be cut. Become.

When this fish body support is incorporated into a cutting blade that only moves up and down at a predetermined position, or when the cutting blade is used with a mechanism that walks together,
It must be formed as a structure having a moving mechanism that translates the fish body support base toward the cutting blade side, and interferes with each cutting blade corresponding to each of the insertion parts for the cutting blade. A drive mechanism that allows a movement that can be inserted without performing, and that is sufficient to move the fish support and has sufficient driving force to cut the placed fish;
For example, it is realized by a device using a driving source such as a motor, or a device that reciprocates using a fluid pressure such as an air cylinder or a hydraulic cylinder.

The cutting blade portion has a function of completely cutting the fish body in a round slice. Usually, the cutting blade portion is a group directed in a predetermined direction at a predetermined interval that can be inserted into the insertion portion from above or from the side of the fish body support base. Although it should be combined as a thing, in some cases, it is composed of only one piece, which is repeatedly moved to the position of each insertion part of the fish support base, and repeatedly operated to stop It must be capable of cutting vivid cuts like hard knives, such as hard parts such as scales and spine, and soft parts such as built-in, for example, formed in a long blade shape,
It can be cut while reciprocating or at once,
Alternatively, it is possible to move while rotating a sharp circular edge formed in a circular disk shape and cut it at a time, as shown in the examples described later, A rotary blade having a large number of saw blades with a rounded sword shape may be employed so that cutting can be realized with smooth strokes as much as possible.

The cutting blade portion may be combined with a structure in which the fish support base is fixed (including a structure that moves to a predetermined position and becomes fixed), or a mechanism in which the fish support base moves together. In such a case, it is necessary to incorporate a moving mechanism that enables the cutting blade portion to move toward the fish body support base side, and it does not hinder cutting driving of the cutting blade portion. It is desirable to use a drive source provided separately from the cutting drive mechanism portion, and should exert sufficient cutting force and movement amount, as in the case of the fish body support table described above. A known driving source such as a motor, an air cylinder, and a hydraulic cylinder can be employed. In the following, the structure of the present invention will be described in detail, together with the embodiment shown in the drawings.
