JPH0416143A - Removing method for fish gut - Google Patents

Abstract

PURPOSE:To carry out efficiently the removal of fish gut, etc., by rotating a belt while holding a fish body in a specific fashion to carry it backward during which it is cut open and its gut, etc., is removed. CONSTITUTION:For removing the gut, etc., of a fish, the belts 4, 4 of respective belt rotating mechanisms are rotated in advance, and in such a state that the head of the fish is removed or not removed, the fish body is put through a sticking rod 6 in a normal attitude, i.e., from the mouth to anus with its belly downward. Thence, when the fish body is pressed against the front of the gap of the facing belt part with its attitude kept as it is, the body is gripped into the gap with its normal attitude and carried backward as it is with the belt rotation. During the carriage, in the case of a fish with roe, the roe is removed with the first and second rotating wheels 9, 10 followed by removing the gut with the third, fourth and fifth rotating wheels 11, 12, 13; then, the resultant body is released from the gripping by both the belt parts and put, via a chute 16, into a basket 17. For a roe-free fish, similar operations may be made; although a roe-scraping operation is not made because of no roe.

Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a method for automatically removing fish internal organs and the like.

"Conventional technology" Traditionally, fish internal organs were removed manually.

``Problem to be solved by the invention'' The conventional method of manually removing fish internal organs, etc., although accurate, had the disadvantage of being inefficient.

The present invention is provided so that the above-mentioned work can be carried out efficiently by digging.

``Means for Solving the Problem J'' A pair of left and right belt rotating mechanisms are used to pass the belt between pulleys fitted on a vertical shaft. A first rotary ring for laparotomy is provided at the lower rear of the stabbing rod, which is formed so as to be able to move rearward at the same speed while maintaining a gap, and protrudes from within the front lower part of the gap to the front of the gap. At the bottom of the above-mentioned gap, a second rotary wheel for scraping out fish roe and a rotary wheel of the same number for removing the roe are arranged rearward one after another, and the above-mentioned piercing rod is used to reach the anus from the mouth side. Penetrate the fish body into an upright position,
The mouth side is inserted into the gap between the front ends of both belt parts, and the belt rotates while the fish body is being held in place. While the fish body is being transported backwards, the belly is opened using each of the rotating wheels and the internal organs etc. are removed. Features.

``Example'' 1.1 is a belt rotation mechanism provided as a pair of left and right, in which pulleys 3, 3 are fitted onto vertically provided shafts 2, 2, and a belt 4° 4 is strung between the pulleys. I did it,
The opposing belt portions of each mechanism are configured to be movable rearward as shown to the right in the figure at the same speed while maintaining a gap for holding the fish body between the belt portions. Flanges 4 are attached to the top and bottom of each pulley to prevent the belt from being pulled out from each pulley.

A pedestal 5 is placed horizontally below the gap, and a stab rod 6 projects from within the front lower part of the gap above the front part of the pedestal toward the front of the gap. As shown in FIGS. 3A and 3B, the piercing rod is formed so as to be able to pierce the fish body from the 70 part side to the anus, and in the case of an egg-bearing fish, the ovarian follicle 8 is removed by the piercing. Provided so that the rod can be pushed upwards. It is preferable that the stabbing rod has an inverted U-shape and a groove is vertically provided on its lower surface as described later.

At the lower rear of the stabbing rod 6, there is provided a first rotary wheel 9 for abdominal dissection of a fish body, the outer periphery of which is a blade. The rotary ring is preferably provided so that its outer peripheral cutting edge enters shallowly into the groove on the lower surface of the stabbing rod.

Behind the stabbing rod 6 and below the above-mentioned gap, there are a planar-shaped second rotary wheel 10 for scraping out follicles, a third rotary wheel 11 for incising internal organs, and a fourth rotating wheel for scraping internal organs. The wheel 12 and the fifth rotary wheel 13 for removing internal organs are sequentially arranged rearward.

The second rotary wheel 10 is shaped like a brush as shown in the figure, the third rotary wheel 11 is a disk with blades attached to its outer periphery, and the fourth rotary wheel 12 is a circular disk with blades attached to its outer periphery. Further, the fifth rotary ring 13 is a disk having brushes arranged around its outer periphery.

Since the second rotary wheel 10 is used to remove the follicle without damaging it, the outer circumference of the tip of the brush has a larger outer diameter than the first rotary wheel 9 for incising the belly of the fish. Also, the third, fourth,
Each of the outer circumferential circles of the fifth rotating ring has a larger outer diameter than the outer circumferential circle of the second rotating ring so that the outer circumference reaches the upper part of the fish belly. Each of these rotating wheels is fitted onto the shaft 14...
Each shaft may be supported by a frame (not shown) provided on the left and right sides of the belt rotation mechanisms 1, 1 described above, or when the pedestal 5 is provided as described above, each shaft may be mounted below the pedestal. The shaft is placed horizontally, and long holes 15 are formed in each rotary wheel for insertion and for taking out excised follicles or internal organs.

To remove internal organs, etc., first remove the belt 4 of each belt rotation mechanism described above.
, 4, and then, as shown in Figures 3A and 3B, with the head not removed or with the head cut off, place the fish body on the piercing rod 6 in a normal position from the mouth side to the anus. In other words, stab the fish with its belly facing down.

Next, when the fish body is pushed into the front end of the gap between the opposing belt parts in that position, the fish body is caught in the gap in its normal posture, and is sent backward as the belt rotates, and during the transfer, the fish body is fertilized. If it is a fish, the first and second rotating wheels9.10
After the follicle is removed at 3rd, 4th, and 5th rotating wheels 11.
12.13, the viscera is removed and released from the grip by the rear belt section of the evisceration, and then the chute 16
It is housed in the brush 7117 via. The same procedure may be applied to eggless fish, however, in this case, since they do not have ovarian follicles, they are not scraped out. The number of the third to fifth rotating wheels described above can be increased or decreased as appropriate by changing the shape of the rotating wheels.

"Effect of the Invention J The present invention has the above-mentioned configuration, and has a vertical shaft 2.2.
A pair of left and right belt rotation mechanisms 1.1 for passing a belt 4 between pulleys 3, 3 fitted on the Since it is formed so that it can move backward at high speed, it is possible to automatically transport the fish from the front end to the rear end between the opposing belt parts while maintaining the erect posture of the fish by holding the belt parts. Since the stabbing rod 6 is protruded from the front lower part of the clamping gap to the front of the gap, and the first rotating shaft 9 for fish abdomen dissection is provided at the rear and lower part of the original vibration, the piercing rod 6 is inserted so as to penetrate from the mouth 1ltIl side to the anus. By penetrating the fish,
In the case of egg-bearing fish, the follicles can be pushed upwards by the piercing rod, so that the first rotating wheel does not damage the follicles and prevent the roe from being dispersed.

Furthermore, as described above, the fish is stabbed in an upright position with the stabbing rod, and the fish is inserted from the mouth side into the gap between the front ends of the belt parts facing each other, and the fish is held between the front ends of the belt parts, and the belt rotates while being held. During the backward transport of the fish body, the abdomen is opened using each rotary wheel and the follicles and internal organs are removed, making it easy to remove them.
