Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a series of eel processing devices such as an automatic eel supply device, an eel perforation device, an automatic eel cutting device, and an adsorption device with a built-in eel.

[0002]

2. Description of the Related Art The processing of live eels, especially the back-cleavage incision work of live eels, is a labor-intensive operation, and even a skilled cook can process 30-50 kg or 300-400 fish per day. The ratio of labor costs to the price of processed eels is enormous. Therefore, various methods and devices for dorsal dissection of live eel have been proposed.

For example, in the method for cutting continuous eel back cracks disclosed in Japanese Examined Patent Publication No. 53-18440, a live eel is introduced into a predetermined position of a guide tube and then energized to be in a temporary dead-rigid state. The needle is pierced and the eel is transported downward to cut the back fissure leaving the abdomen with a rotary cutter for back fissure cutting.

Further, Japanese Patent Publication No. 57-1974 discloses that
The eel is sandwiched between a pair of left and right holding belts and transferred, and a notch reaching the lower part of the spine of the eel is made by a standing blade arranged between the holding belts, and then a lower guide is slidably contacted with the lower part of the eel spine. The invention has disclosed an invention of an eel processing device that incises the eel by cutting both sides of the spine of the eel from the left and right with a pair of left and right fillet knives inclined toward the upper end toward each other.

[0005]

However, in any of the above-mentioned methods of the present invention, a notch reaching the spine of the eel is made by a single centrally placed cutter or cutting blade for back cleaving, and then the center of the eel. Left and right sides of the spine of the eel are cut in a V shape from the left and right with a pair of left and right skeleton cutting cutters or fillet knives inclined toward each other, leaving a lot of meat on the spine. As a result, eels are incised, resulting in a poor product yield. In addition, the internal organs of eel, especially the liver, are separated from the meat along with the bone, but they are severely damaged and lose their value as commercial products.

Furthermore, since the live eels are processed in the energized asphyxia state, in the latter invention, it is necessary to manually set the eels in the asphyxia state on the conveyor, which makes automation and continuation of the work difficult, and it is unnecessary. Requires human labor. In addition, when the live eel is brought to a state of electrical asphyxia, the workability is improved because the eel does not move, but there is a drawback in that the taste of the eel decreases and the slime appears on the body surface, which interferes with the subsequent work.

The present invention has been made to solve the above-mentioned problems of the conventional live eel processing apparatus.
A continuous automated processing device for live eels that can improve product yield to the same level as manual work, use edible parts without waste, and remove eel internal organs without damaging the eels The purpose is to provide.

The opening / closing door 22 on the outlet side of the eel supply pipe 2
4 can take out the eel one by one from the eel separation pipe 16.

The suction mouthpiece 36 of the live eel perforation device has a suction hole 40 having an eel head-shaped space 38 therein and a suction hole 42 communicating with the tip of the head-shaped space 38 of the suction hole 40.
Therefore, the head of the eel supplied from the eel automatic supply device is sucked into the suction hole 40. The suction hole 40 is provided with a through hole 46 penetrating it laterally. Since the perforation needle 52 is inserted into this through hole 46 and the perforation cylinder 52 is pushed from behind by the perforation cylinder 54,
The head of the eel is fixed to the mouthpiece 36 by a perforation needle 52.

The eel whose head is fixed to the mouthpiece 36 is fixed on the cooking table by the eel fixing device 100 of the automatic eel cutting device. Plate cam 88 for blade up / down and plate cam 90 for blade rotation
Is set at a predetermined position by the air cylinder 86, and the blade front-rear plate cam 98 is set at a predetermined position by the air cylinder 96, the blade vertical shaft 68, the blade rotating shaft 70, and the blade front-back shaft 92 are respectively attached to the tips. Since the attached rollers 82, 84 and 94 are pressed against the plate cams, the blade 72 attached to the blade unit 66 is set at a predetermined height and a predetermined blade angle at a predetermined front and rear position. It

Then, the gear 64 is driven to drive the chain 62.
Since the moving frame 56 moves when the tape is wound, the blade unit 66 moves while being guided by the rail 60. When the blade unit 66 moves, the rollers 82, 84 and 94 attached to the tips of the blade vertical shaft 68, the blade rotating shaft 70 and the blade front and rear shaft 92 respectively move the blade vertical plate cam 88 and the blade rotating plate cam 90. And the blade front / rear plate cam 98, so that the blade up / down plate cam 8 moves.
The cutting depth of the cutting tool 72 is adjusted by 8, the cutting angle of the cutting tool 72 is adjusted by the cutting tool rotating plate cam 90 device, the cutting front and back positions of the cutting tool are adjusted by the cutting tool front and back cutting plate cam 98, and the eel is placed along the spine. You can make an incision without damaging the internal organs. In this embodiment, the plate cam is used to adjust the cutting angle and the cutting depth of the blade 72, but a servo motor may be used instead of the plate cam.

When the eel is incised, the suction plate 104 is held downward by the elevating device of the adsorption / separation device of the eel, and descends toward the internal organs. The suction plate 104 has a recess 106 into which an eel is embedded and a suction hole 108 communicating with the recess 106.
Since the eel internal organs are adsorbed, the front and back of the internal organs are cut by the cutting blades 112 that elastically project downward at both ends of the suction plate, and the eel internal organs are adsorbed and separated.

[0033]

[Effects of the Invention] Since one eel thrown into the hopper of the automatic eel feeder feeds into each eel separation pipe, one eel is taken out by the eel supply pipe sequentially connected to the outlet of the eel separation pipe. You can The suction mouthpiece of the live eel perforation device can adsorb the head of the eel, so by inserting a perforation needle into the through hole provided in the mouthpiece,
The eel can be perforated automatically without requiring human intervention. A blade unit of the automatic eel cutting device is attached to the blade unit so that it can be moved vertically downward and freely rotatable, and if this blade unit is horizontally moved by a horizontal movement device along a fixed eel, the blade unit will move horizontally. Since the cutting depth of the cutting tool is adjusted by the cutting tool vertical movement device, the cutting angle of the cutting tool is adjusted by the cutting tool turning device, and the cutting position of the cutting tool is adjusted by the cutting tool longitudinal movement device. The incision can be made along the spine without damaging the internal organs. The adsorption disc of the eel internal adsorption and separation device is provided with a recess into which the built-in eel is inserted and a suction hole communicating with the depression, so that the eel internal is adsorbed and elastically protrudes downward at both ends of the adsorption disc. The cutting blades cut the front and back of the internal organs, and the eel internal organs are adsorbed and separated.
