Abstract

PURPOSE:To obtain an apparatus for slicing a salmon body into three slices along the backbone and capable of easily dividing the meat from bones by using a lower cutter, an upper cutter and an inclined cutter. CONSTITUTION:Head, guts, tail, dorsal fin and anal fin are removed and the dressed headless fish body is transferred with a pair of right and left endless belts 120 extended between pulleys. A lower cutter 130 to incise the tail part of the headless fish body and an upper cutter 150 to incise the back of the body are placed between the endless belts 120 at prescribed distance on the axial line of the endless belt 120. A pair of right and left inclined cutters 180 to cut off the middle bone from the body are placed in such a manner as to position the tip ends of the blades on nearly the same axial line as those of the above upper and lower cutters 130, 150. The headless fish body is guided with a slitted guide member 107 placed between the endless belts 120 and between the upper and the lower cutters 130, 150.

Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is applicable to three types of salmon, in which fish bodies such as salmon and trout can be divided into meat parts and bone parts using a lower cutter, an upper cutter, and an inclined cutter. The purpose of the present invention is to provide a sheet-grating device.

``Prior Art'' A device for cutting fish bodies such as salmon and trout into three pieces is, for example, as shown in FIGS. 1 and attached to the shaft 2 so as to face each other, and the first cutter 1
, 1', second cutters 3, 3' are attached to the shaft 4 at a distance corresponding to the thickness of the dorsal fin.

A fish body guide rail 5 is provided in the gap between the first cutters 1 and 1'.
A dorsal fin suppressing member 6 is provided above the dorsal fin suppressing member 6 for regulating the position of the dorsal fin.

Therefore, when the fish body 7 whose head has been cut off in advance and whose internal organs have been cut off by opening its abdomen is fed while being held between conveyor belts 8 and 9, the dorsal fin portion is first cut off by the second cutter. is cut, and the first cutter separates the left and right body and the bone part, and the bone part passes between the first cutters and hits the separator 10 and falls down, so it is separated into the bone part and the body part. Ru.

``Problem to be Solved by the Invention'' However, since the first cutter and the second cutter are attached to the shaft with a required spacing left and right, the portion of the meat that is shaved off from the portion of the meat that corresponds to the required spacing. Because some parts of the cutter fall together with the bones, the yield rate is extremely poor. At the same time, it takes considerable skill to feed the dorsal fin, tail fin, etc. straight into the left and right centers of the first and second cutters. It takes.

Therefore, a fish body is prepared in advance with its head, internal organs, dorsal fin, tail, and anal fin removed, and the fish body is moved by an endless belt that transports it at the required speed and a guide member that guides the fish straight. The lower part of the abdomen is cut into the rear part of the fish body using the lower cutter, and the back part of the moving fish body is cut with the 8-part cutter.Finally, the middle bone is separated from the fish body using the left and right inclined cutters, and at the same time, the half body is formed on the left and right sides. The technical problem of the present invention is to minimize the number of perches and at the same time remove the dorsal fin, tail, etc. in advance so that even an inexperienced person can easily feed the fish.

"Means for Solving the Problems" The configuration of the present invention for solving the above technical problems is as follows.

That is, the pretreated headless fish body is run through a three-piece grating device for salmon, which has been pretreated by cutting off the head, removing internal organs, cutting off the tail, and cutting off the dorsal and anal fins. Endless belts are provided on the left and right sides via a boob, and a lower cutter for cutting the rump of the fish body and an upper cutter for cutting the back of the fish body are provided between the endless belts at a predetermined interval on the same axis as the endless belt. , and an adjustment mechanism is provided on the frame side to enable height adjustment of these upper and lower cutters, and furthermore, in order to separate the backbone from the fish body, the cutting edges of the left and right inclined cutters are approximately on the same axis as the upper and lower cutters. Located in
The salmon is characterized in that a height adjustment mechanism is provided on the frame side, and a guide member with a slit for guiding the movement of the fish is provided between the endless belt and between the upper cutter and the lower cutter. The purpose of the present invention is to provide a three-piece grater device.

``Function'' Since the head, internal organs, tail, and dorsal fin and anal fin are removed from the fish body in advance, it can be easily placed on the guide member between the left and right endless belts, and the lower cutter and upper cutter are the same. Because it is set on the axis and slightly offset from the center of the fish body, the cutting edge of the double force blade comes into contact with one side of the backbone and the rear part of the fish's abdomen (butt part). Then, an incision is made into the back of the fish body, and the middle bone is smoothly removed from the fish body using the left and right slanted cutters.

"Effects of the Invention" (1) 8 The fish bodies fed into the device of the present invention have been pre-processed by cutting off their heads, removing internal organs, cutting off their tails, and cutting off their dorsal and anal fins. The cut is made along the upper and lower cutters provided, and the back bone is separated from the fish body using an inclined cutter, and at the same time it is divided into left and right pieces, resulting in a higher yield compared to conventional two-piece cutters. Since the fins and anal fins have been removed, the cutter can cut easily and the fish body can be fed between the endless belts.
This method has advantages such as not requiring skilled workers.

(2) The first raised part of the guide member with slits attached to the loading side plate can receive and stop the butt of the pretreated fish body, so the fish body can be fed straight between the endless belts. A slit is formed in the rear inclined surface of the second raised part of the guide member with a slit, and since the rotary blade of the lower cutter protrudes from the slit, the open abdomen of the fish held by the end schelt is cut open. At the same time that the fish is held in the horizontal part of the second raised part, the tail part is cut straight without bending.Furthermore, since the horizontal part of the second raised part does not catch the entire fish body, the cut of the upper cutter is cut in the horizontal part of the second raised part. It's done smoothly.

(3) You can easily adjust the height of the upper and lower cutters and the angle of the inclined cutter by operating the handle of the adjustment mechanism provided on the frame side and the handle on the cutter side, so you can smoothly grate three pieces of fish. It can be carried out.

(4) The centering roller for heald spacing adjustment that actively presses against the left and right endless belts is constantly pulled inward by a spring by an arm fixed to the shaft of the roller. The left and right endless belts can be expanded or contracted depending on the size of the fish to be fed.

It is clear that the present invention can be modified in various ways without departing from the spirit described in the claims, and these modifications are within the scope of the copyright of the present invention.
