In the embodiment, the difference is about 2 mm. The circular saw cutter 23 may be integrally fixed to the rotary disk cutter 15a (or 15b), or may be equipped with a separate driving means 35 so that the circular saw cutter 23 can be rotated at different rotational speeds. Belong to. Further, the shape of each cutting edge of the circular saw cutter 23 may be asymmetrical or symmetrical in the rotational direction.

Operation of the embodiment In the aspect of the first aspect of the invention, the included angle α of the pair of rotary disk cutters 15a, 15b is determined according to the size of the fish species. That is, a large fish body has a large included angle α, and a small fish body and a long elongated body has a included angle α of 5 ° to 20 °.

Thus, the holding belt conveyor 13, the pair of rotary disk cutters 15a and 15b, and the circular saw cutter 2 are provided.
3 is rotated in the forward direction, and the fish is fed between the holding belt conveyors 13 so that the lower side of the fish contacts the support surface 11, the fish body A produces a pair of rotary disc cutters 15 on both sides of the middle bone.
Simultaneously with the division by a and 15b, the mid-bone portion located in the middle is crushed and ground by the circular saw cutter 23 in sequence, and when the full length of the fish body is opened, the mid-bone portion is completely removed.

[0015] are then attached <br/> pressure is even more of a following structure in FIG. That is, a slit 26 into which a lower cutting cutter 25, which will be described later, can be inserted is formed in a portion of the support base 10 just below the rotary disk cutters 15a and 15b, and the width B is approximately the thickness of the fish body. There is no particular limitation as long as it is narrower, but it is preferable that the thickness is smaller than the thickness of the fish A.

In the lower cutting cutter 25, a pair of second rotary disk cutters 27 having the same diameter are provided on a common rotary shaft 29.
a and 27b are provided, and the tip circle 2 from this outer diameter in the middle
8a is slightly smaller (about 3 to 10 mm), and a second circular saw cutter 28 having a thickness slightly thicker than the upper circular saw cutter 23 is provided, and a bearing 31 supporting this rotating shaft 29 is an arm whose vertical position can be adjusted. The lower cutting cutter 25, which is provided on the member 33, is capable of projecting and retracting the lower cutting cutter 25 from the lower side of the support base 10 with respect to the support surface 11 and at the same time as the upper rotary disk cutters 15a and 15b. It is a position that can be wrapped on the outer side of.

As for the operation of the added portion, if the lower cutting cutter 25 is submerged under the support base 10 and operated, the same operation as the embodiment is achieved. Slit the lower cutting cutter 25
6, projecting above the support base 10 to bring the second rotary disk cutters 27a, 27b and the peripheral disk edges of the upper rotary disk cutters 15a, 15b located on the support base into close contact with each other, When the fish A is driven and fed, the fish A is divided into left and right parts, and the middle bones and the upper and lower rotating disk cutters 15a, 15b and 27a, 27b.
The skin between the parts sandwiched between them is also completely crushed and removed.

[0016]

In the present invention configured and acting as described above, at the same time when the fish body A is opened, the mid-bone portion is crushed and scraped off by the circular saw cutter 23, so that the mid-bone portion is particularly erected. There is no need, and there is no need for a separate medullary bone removing device on the downstream side, so that the device can be simplified, the length of the holding belt conveyor 13 can be short, and the device itself can be downsized.

Further, since the bones and a part of the fish meat are crushed in the middle bone portion, it can be recovered and used as a raw material for a kneaded food as a food, a sludge feed or the like. When the included angle α of the rotary disk cutters 15a and 15b is within the above range, the amount of fish meat attached and removed together with the mid bone is small and the included angle is small. Is often scraped off, resulting in poor yield.

Effects of Embodiments When the support surface 11 is the flat belt conveyor 12, the fish body conveyance resistance is small. On the contrary, in the case of the flat belt conveyor 12, the fish body conveyance resistance is small. On the contrary, if the support base 10 without the flat belt conveyor 12 is stationary, the structure is simple.

The circular saw cutter 23 is a rotary disk cutter 15.
In the case of the embodiment fixed to a (or 15b), the transmission means of the circular saw cutter 23 is not particularly required. In the example in which the circular saw cutter 23 is located coaxially with the rotary disk cutter 15a (or 15b) and the independent rotation speed can be selected by the separate drive means 35, the type, shape, bone or meat of the fish body can be selected. The number of revolutions of the circular saw cutter 23 can be selected according to the nature and freshness, and the shape of each blade of the circular saw cutter 23 can also be selected according to the type and purpose of the fish.

2 and 3, the rotary disk cutters 15a and 15b are provided with a pair of third rotary disk cutters 34, which are slightly overlapped with the rotary disk cutters 15a and 15b, so that the rotary disk cutters 15a are Immediately before being cut open with the pair of third rotary cutters 34, first, the cuts along both sides of the middle bone are made by the pair of third rotary cutters 34, so that the rotary disc cutters 15a, 15b can be easily cut, and the open or cut can be made more neatly.

In addition, as shown in FIGS. 3 and 4, a slit 26 is provided in the support base 10, and a second rotary cutter 27a,
27b and the second circular saw cutter 28 is provided on the slit 26 so that the second cutter 27a and 27b can be freely retracted and retracted.
By slightly wrapping it with 5b, the fish A can be completely divided into left and right.

When the width B of the slit 26 is narrower than the thickness of the fish body A, there is no possibility that the fish body A will drop suddenly even when the fish body A is held by the pair of holding belt conveyors 13 and conveyed. Further, in the case where the lid 32 can be attached to and detached from the slit 26, when the lid 32 is fitted into the slit 26, the position of the fish body A becomes more stable when implemented as the first invention (see FIG. 1).
