Operation 1 In this particular invention, the rotary disc cutter is rotated at high speed, and the fish body is placed sideways between a pair of fish feeding guide members, with the tail of the horse mackerel at the head, and then fed into the rotary disc cutter in one direction. At this time, the tail of the fish is placed on the fish feed-out guide member in advance, and the fish body in the scale guide groove portion or the carry-in edge portion of the fish feed-out guide member is lightly pressed downward by hand or with a suitable suppressing member.

In this way, the hard scale part near the caudal fin is curved convexly downward, and the hard scale part is pushed into the scale guide 171y, and the scales in this part are lower than the rotary disc cutter, and the fish body is transported. Accordingly, the scales are cut off by the peripheral edge of the rotary disc cutter, and when the hard scale part passes through the peripheral edge part, the suppressing force applied to the fish body is released, and the fish body is guided to be rapidly sent out one by one. The scales are guided and sent out by a member, and only the scales fall downward from the scale discharge [1] in the scale guide groove.

The width of the fish body that has passed through the hard scales is wider than the scale guide groove, so even if the above-mentioned suppressing force is applied continuously, the fish body will hardly curve downward in a convex manner. The fish meat part cranial to the head is not removed.

1) Remove the hard scales from both the left and right sides of the horse mackerel in the same way.

In the invention of claim 2, there is only one rotary disc cutter for cutting off the scales, and the direction of rotation thereof is not particularly limited.

In the third aspect of the invention, when the two rotary disc cutters are rotated, they rotate in opposite directions. The direction of rotation of these is preferably the forward direction in the fish feeding portion.

Then, as in the specific invention, when the mackerel is guided by the fish feeding guide member and fed in, the hard scales are cut off by the two rotary disc cutters and the scales are removed downward from the discharge port.

In the invention set forth in claim 4, the pair of fish feeding guide members are used by moving and fixing the interval widely to roughly match the fish width of the school of fish to be fed.

In the invention of claim 5, the fish feeding guide member is moved back and forth in the transport direction and adjusted to a position where the scales can be completely removed.

It will be pushed into 2.

Other operations are the same as the device of this invention.

(Configuration of Embodiment 2) This is an embodiment according to claims 3 to 5, and FIG.
This is shown in FIG.

The same reference numerals as in the first embodiment indicate the same structural members or parts and perform the same functions.

The difference is that there are two rotary disk cutters 15a and 15.
b are fixed to separate vertical shafts 12a and 12b, and these vertical shafts 12a and 12b are mounted on the machine frame 13 parallel to each other and symmetrically with respect to the direction in which the fish are carried in, and the two rotary disc cutters The peripheral edges of the cutters 15a and 15b overlap each other and are provided very close to each other, and the two rotary disk cutters 15a and 15b are fixed to the vertical shafts 12a and L2b so as to rotate in opposite directions. The gears 32a and 32b having the same number of teeth are meshed with each other.

The scale cutting position is located at the intersection point P of the peripheral edges 17a and 17b of the two rotary disk cutters 15a and 151), where the direction of rotation coincides with the fish loading direction, that is, in the forward direction. A fish feeding guide member 18 and an opening inner groove 22 are provided toward this (see FIG. 4).

The fish delivery guide member 25 is attached to the table 10 so that its carry-in edge 26 is parallel to the line connecting the two vertical shafts 12a12b when viewed from above. As in the first embodiment, the safety cover 31 is fixed to the table so as to completely cover the other parts except for the intersection of the peripheral edges 17a and 17b.

The operation of the second embodiment is the same as that described in claims 3 and 5, so a description thereof will be omitted.

In each example, one table is provided with one set of rotary disk cutter, fish feed guide member, opening inner groove, and fish feed guide member, but two sets of the table of Example 1 or Example 2 are shown. Alternatively, the devices of Example 1 and Example 2 can be arranged side by side, and only these tables can be used as a single common table, so that workers of 2 or more places can work at the tables A and - at the same time. Even if there is one, it is included in the embodiment of this invention (see FIG. 6).

C. Since the specific effect invention is configured and works as described above, the jlA is laid down on its side and positioned between the pair of fish feeding guide members with the tail at the top, and the tail is attached by lightly touching the root part. When the fish is fed while being pressed against the table surface, the protruding hard scales B near the tail of fiA located on the lower side will be lower than the peripheral edge of the rotary disc cutter, and as the fish is fed, the scales B will be It was cut out with a rotating disc cutter.

The fish falls to the lower side of the top plate from the outlet of the opening inner groove, and is guided by the fish delivery guide member and moves upward, and the fish meat part and scales B are completely separated.

In addition, when the hard MB is removed using a rotary disc cutter, even if the fish body receives force in a direction different from the feeding direction due to the rotational force of one cutter, the fish body is supported by the fish feeding guide member, so the fish body will not move on the table surface. It does not move from side to side, and the 13 parts of the fish's hard scales that protrude downwards fit into the inner groove of the fish.

Since the fish body easily curves downward and convexly, and 16 parts of the fish are supported by the fish delivery guide member, the scales B can be cut with almost no lateral pressure applied to the rotating rotary disc cutter, and the scales B can be suppressed. It is safe whether the method is manual or mechanical.

Furthermore, since the width of the opening inner groove is wider than the width of the hard scale B and narrower than the width of the fish body, only the hard scale B portion fits into the opening inner groove, and only this part is removed. , even the fish flesh will not be cut off indiscriminately.

In the apparatus described in claim 2, since there is only one rotary disc cutter, the structure is extremely simple, the cost of the apparatus is low, and the cost for cutting scales does not increase.

In the device described in claim 3, since the scales B are cut from both sides by the rotary disc cutter that rotates in opposite directions, the force on the fish body in a direction different from the transport direction due to the rotation of the rotary disc cutter is canceled out. Since only the force in the transport direction is applied, the fish body does not shift from side to side, and almost no force is required for transport. In the fourth aspect of the present invention, the distance between the pair of fish feeding guide members can be adjusted to an optimum value depending on the size of the fish school.

In the fifth aspect of the present invention, since the fish feeding guide member can be moved in the direction in which the fish is carried in and taken out, the scales B can be adjusted by adjusting the movement according to the type and size of the mackerel A.
can be removed to minimize the amount of fish meat removed.

(Effects unique to the embodiment) In the first embodiment, the effects of the first, second, fourth, and fifth claims are achieved.

In the second embodiment, the effects described in claims 1, 3, and 5 are achieved.

In the two embodiments described above, at least the two sides of the fish feed-out guide member 25 on the carry-in side are formed with a sloped surface 27 that is sloped low, so that when the fish tail part is pressed against this part, The fish body surface that comes into contact with this part is sloped low on the carry-in side following this slope 27, and the part of the hard scales B is curved convexly. Therefore, not only does the pressing force not act on the rotary disc cutter 15 or 15a and 15b at all, but also because the position of the pressing hand or the suppressing member is above the fish feed guide member 25, the area around the rotary disc cutter 15 that rotates by mistake. Contact Edge 17.

It is safe because there is no risk of injuring the hand or damaging the peripheral edge 17.
