In this case, it is desirable that a cushion material such as rubber is adhered to the inner surface of the supply pipe so that the body of the raw eel is not damaged by the supply pipe being too closed. In this state, as shown in the vertical cross-sectional view of FIG. 4B, the dorsal fin projects from the upper slit 21a and the lower slit 2
1b, the lower end of the abdomen protrudes slightly, and the head and neck protrude from the front end of the supply pipe 21.

When the supply pipe 21 is closed, the frontmost block among the multiple holding blocks 60 arranged on the peripheral portion of the rotary drum is positioned on the extension line of the supply pipe and is on standby. . A head stopper 41 extending in the direction crossing the peripheral edge of the rotary drum is provided at the front end of the most up-to-date holding block, and raw eel enters the supply pipe and moves forward, and the head of the eel is the head stopper. The supply pipe is adapted to be closed as described above when it comes into contact with.

After the supply pipe is closed in this way, a so-called perforation is performed in which the head of the raw eel is pierced with a needle in order to fix the head of the raw eel to the cutting edge holding block. For this reason, a piercing needle protrudes inward from the inner surface of the state-of-the-art holding block, and the holding block can be freely opened and closed in the radial direction of the body of the eel.

Here, the holding block 60 and its opening / closing mechanism will be described with reference to FIG. The holding block 60 has a pair of L-shaped cross-sections 60a, 60a disposed on the periphery of the drum 30 so as to face each other, and the lower surfaces of these holding pieces are attached along the outer peripheral side of the rotary drum. It is slidably mounted on the receiving plate 32. A recess 32a having an arcuate cross section is formed on the upper surface of the receiving plate 32 along its longitudinal direction, and this recess is for accommodating and stably holding the lower trunk of the eel.

In the position where the cam surface of the fixed cam 38 protrudes toward the rotary drum, as shown in FIG. 5A, the lower portion of the one holding lever 44 is pushed toward the rotary drum 30 so that the shaft 43 is centered. The upper part swings toward the fixed frame 2 side. On the other hand, the other holding lever 44 has gear teeth 44a, 44
Due to the engagement of a, the upper portion swings toward the rotary drum side against the tension spring 42. Thereby, both holding pieces 60a,
60a move in a direction to isolate each other. On the other hand, when the cam surface of the fixed cam 38 is recessed toward the fixed frame 2, the holding levers 44, 44 are rotated in the direction approaching each other by the tension spring, and the upper end The holding pieces 60a, 60a move so as to hold the eel. In the present embodiment, thirteen holding blocks 60 having the same configuration as those described above are provided close to each other and over substantially half the circumference of the rotary drum. The cam surface of the fixed cam 38 for opening and closing the holding block is closed when each of the holding blocks 60 passes through the distal end of the supply pipe 21, and expands when reaching above a discharge chute 5 described later. It is formed to open. In addition, the above-mentioned holding piece 6

It is pivotally attached to the base of the perforation lever 40 via. The tip of the perforation lever 40 is attached to the shaft portion 52c of the bearing block attached to the fixed frame 2 so as to rotate together with the shaft portion 52c.

With the above construction, when the perforation lever 40 is rotated in the direction of the arrow in FIG. 5B, the dog-legged lever 49 is rotated counterclockwise via the link 49b, and the sliding movement is caused accordingly. The rod 48 moves to the outside of the fixed frame 2 by the action of the spring 49a, and the inner end of the sliding rod moves so as to be flush with the cam surface of the fixed cam 38. Since the driven roller 47 is in pressure contact with the inner end of the sliding rod, the driven roller 47 moves on the same plane as the cam surface with the movement of the sliding rod 48, and the driven roller 47 is attached. The holding lever 44 and the other holding lever opposing the holding lever 44 mutually rotate in the direction of holding the eel by the action of the spring 42. At this time, the piercing needles attached to the cutting-edge holding block pierce the head of the eel from both sides to perforate the eel's head and fix it to the cutting-edge holding block.

As described above, it is possible to prevent the raw eel from moving by itself by making a perforation on the head of the eel, and the eel placed on the receiving plate 32 is rotated by the rotary drum 30.

Although the present invention has been described with reference to the above preferred embodiment, the present invention is not limited to this embodiment, and various modifications can be made. For example, in driving the rotating drum, the driving motor may be omitted, a gripping member or the like may be provided on the outer side of the rotating drum, and the rotating drum may be driven manually without using electric power. In this case, the purchase cost and the running cost can be reduced.

If necessary, the rotation speed of the drive motor 3 can be adjusted, and the rotation of the rotary drum 30 can be controlled to obtain a desired incision separation speed. Incision separation work can be realized and high quality eel can be supplied.

In the eel cutting device of the present embodiment described above, it is easy to cut only the body below the neck without cutting the head, and as a result, the head is halved as in the conventional case. It is possible to enhance the commercial value of the eel cut by the device of the present invention as compared with the cut eel. In addition, the eel can be paralyzed by cutting the neck to facilitate the subsequent pinching by the pinching block, and further, the eel bleeding can be promoted to maintain a good taste.

The dorsal fin of the eel can be held between the divided supply pipes to keep the eel in a predetermined posture, and the incision work thereafter can be performed accurately and reliably.

In addition, since the above-mentioned device is configured to have a cutter for separation with built-in bone and a driving mechanism for the cutter for separation, since the method of spraying water or the like is not used when separating the spine and built-in from the eel, water pressure to the eel is not used. It is possible to prevent deterioration of meat quality due to absorption of water and water.

Further, in the above apparatus, since the holding block is provided with the holding block, the holding block can correspond to the thickness dimension of the body of the eel, and can hold the eel in close contact with the body without substantially adjusting it. In addition, it is not necessary to increase the elastic force of the elastic member as in the conventional case, and the eel can be held and conveyed without being damaged, and the deterioration of eel quality can be prevented.

Furthermore, in the above apparatus, a plate-shaped stopper is provided in the lateral direction at the front end of the most up-to-date holding block, and the head end of the eel is brought into contact with the inner surface of the eel head. Since the perforating needle to be fixed is configured to project inward, the eel can be firmly fixed to the holding block by perforation, and the eel can be reliably pulled out onto the drum by the rotation of the holding block.

Further, in the above apparatus, since the receiving plate mounted along the outer peripheral side of the rotary drum is provided with the concave portion, the lower portion of the eel is allowed to enter thereinto, and the entire neck portion is cut when the neck portion is cut. It becomes easy to cut so as not to be cut off and to open so that the body is accurately positioned and not completely divided into two when the body is incised.

Further, in the above apparatus, since the eel neck cutting cutter is provided, the neck portion is surely cut by the turning operation of the operating lever.

Furthermore, in the above-mentioned device, since the pair of leading edge holding levers is configured to be opened more largely than the holding levers of other subsequent holding blocks, the leading edge holding block is provided with a piercing needle. With the provision, it is possible to prevent the puncture needle from entering the leading edge of the holding block.

Further, in the above-mentioned apparatus, since the supply pipe can be opened and closed by turning the operation lever, the opening and closing operation of the supply pipe can be performed by turning the operation lever. It becomes easy to link with driving of the cutting cutter or perforation operation. When the gripping block travels below the supply mechanism, the supply mechanism is configured to swing to a position that does not hinder the travel of the gripping block, so that the gripping block does not collide with the supply mechanism and the rotating drum rotates continuously. Can be possible.

Further, in the above apparatus, since the cutting edge of the eel barrel cutting cutter is constructed so that the cutting edge is thrown into the eel barrel in response to the cam means provided coaxially with the rotating drum, The operation to separate the eel bone and the internal organs afterwards becomes easy.

Furthermore, in the above apparatus, since the eel body incising cutter is composed of two cutters which are arranged at different positions in the rotation direction of the rotary drum, the two cutters are arranged on the periphery of the rotary drum. Since the installed mechanisms do not overlap, the structure can be simplified and the adjustment becomes easy.

[0095]

In the eel cutting device of the present invention, since the body is cut while the eel is being rotated and conveyed as the rotary drum rotates, the eel cutting device is compact and does not require a large installation area. Since it is relatively simple, the manufacturing cost is low, and it can be installed in retail stores.

Further, since the eel body incision cutter and its drive mechanism are provided, it is possible to make an incision with almost no damage to the spine of the eel and the built-in or meat portion, and the yield of the obtained meat portion can be improved.

Further, since the cutter for separating bones and the drive mechanism therefor are provided, it is possible to separate the bones and the internal organs from the eel body without damaging the spine, the internal organs and the flesh. Therefore, since the built-in pieces are hardly damaged and the meat pieces and the liquid in the inside adhere to the meat parts, it is possible to obtain a high quality eel body.

Further, the eel cut and separated by this device is recovered as an eel for broiled eel, and the obtained internal organs can be used as a material for cooking such as liver sucking and the spine as a delicacy material.

Further, according to the present invention, the eel body incision cutter and its drive mechanism, or the bone-containing separation cutter and its drive mechanism are used for eel body incision according to the type and size of the eel. There is no need to attach the cutting edge of the cutter or fine-tune the movement trajectory each time, and extremely easy operability can be realized.
