Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of use" The present invention relates to a method of excising a head from a fish.

“Prior Art” For example, in Japanese Examined Patent Publication No. 60-28252, as a conventional example, a mark for head position alignment is provided on a conveyor for transporting fish bodies, and the head cutting scheduled position is aligned with the mark to convey the fish bodies. Describes a method of feeding into the processing device to cut the head and processing.

[Problems to be Solved by the Invention] As in the above method, it is prudent to align a large amount of fish transferred by a conveyor with a mark provided on the conveyor, and avoid an error caused by fatigue. If it is not possible to do so, the internal organs will be mixed in the pickpocket to deteriorate the quality, and the head cutting position will be roughly estimated, so if you try to avoid the drop in quality of the pickpocket, it is inevitable. It would result in an extra cut of the head.

That is, in order to accurately determine the cutting position of the head, it is necessary to look at the upper surface of the fish body and accurately position the head cutting scheduled position that is known above the conveyor vertically above the mark. Assuming that the fish body is extended upward by the thickness of the fish body, it is necessary to perform a judgment work to match the position of the assumed mark with the head cutting planned position on the upper surface of the fish body, and the judgment work makes the operator tired, Further, the fatigue causes the work to be performed with a rough estimate, resulting in inaccuracy and the above-mentioned drawbacks.

According to the present invention, when a fish body is placed on a conveyor, an irradiation line indicating the position where the cutter descends directly onto the fish body is provided so that the operator's judgment work is unnecessary and the fatigue is removed. In addition, by providing accurate head cutting work, it is possible to prevent the deterioration of the quality of the fish body from which the head has been removed, and to prevent the deterioration of the yield of the processed part by removing the head more than necessary. Is.

[Means for Solving the Problems] A fish body moving belt conveyor having a large number of fish placing trays opening at both left and right side edges of the first belt is fixed to the outer surface of the first belt, and is provided above the belt conveyor. , A second belt for pressing the fish body parallel to the first belt, and the tensioned portions of the first and second belts facing each other are movably movably in the same direction and at the same speed, and one side of the first belt. A cutter is provided outside the edge, and a light emitting area is provided on the vertical surface from the front part of the conveyor to at least the cutter along the first belt side edge on the side where the cutter is provided, and the light emitting area is on the fish body. The irradiation line displayed on the head is aligned with the planned head cutting position, the fish is placed on the plate, and the fish is sandwiched between the belt conveyor and the second belt to be transferred. Along the irradiation line, fish with the above cutter Separate the head from the body.

[Operation] As shown in FIG. 2, the fish body is placed on the placing table so that the irradiation line 17 is positioned on the neck of the fish body, and the irradiation line 17 is kept on the plate of the belt conveyor so that the irradiation line 17 does not come off from the fish neck. Move to.

Then, the upper surface of the fish placed on the plate is pressed by the lower belt portion of the second pressing belt that is annularly stretched above the conveyor, and the fish is clamped and transferred to the right in FIG. . During the transfer, the cutter cuts its head at a position along the irradiation line displayed on the fish neck. The fish body whose head is cut off falls into the bucket 19 from the end of the belt conveyor.

"Example" 1 is a fish head excision machine, in which the frames 2, 2 are provided in parallel on the left and right, and shafts 4, 3 in which pulleys 3, 3 are fitted between the front and rear parts of the vertical middle of the frame, 4 is installed, and the first belt 5 is hung between the pulleys to form a belt conveyor 6. On the outer surface side of the first belt, a large number of fish placing trays 7 that open the left and right side edges of the first belt are fixed at equal intervals, and both ends are fixed to the left and right frames on the transfer start side by the conveyor. The fish mounting plate 8 is installed. When the fish placing plate pushes the fish to the transfer starting end side of the conveyor while the fish is placed on the plate, the fish placing plate rides on the plate 7 which has been moved by the belt rotation at the transfer starting end and remains on the rear side of the conveyor. It is provided to be transferred to.

Above the belt conveyor, a second belt 9 for pressing the fish body placed on the plate is provided in parallel with the first belt 5 of the conveyor. The belt comprises pulleys 11 and 11 of shafts 10 and 10 installed between the front and rear parts above the frames 2 and 2.
It has been suspended in the meantime. As shown in the figure, between the upper and lower portions of the second belt, the left and right ends of the second belt are fixed to the mounting plate 12, and a mounting plate 12 is provided. A spring 13 protruding downward and rearward from the mounting plate ... A roller 14 attached to the lower end. It is possible to press the fish body with certainty by pressing the upper part of the second belt 9 against the upper surface of the second belt 9.

The cutter 15 is provided outside one side edge of the first belt. The cutter is for cutting and removing the fish head that is placed on a plate and is sandwiched between the upper and lower belt portions and transferred backward, and in the illustrated example, it moves up and down and when it descends, Although it is provided so as to cut off the fish head, it may be a rotary wheel type cutter. As shown in FIG. 3A, the cutter that moves up and down in the illustrated example has a blade surface of V
It is preferable that the cutter has a U shape or a U shape shown in FIG.

On the side of the belt conveyor where the above-mentioned cutter is provided, along the side edge of the belt, there is a light emission area on the side edge and on the vertical plane outside the belt.
Form 16 from top to bottom. The light emission area is provided so that a straight irradiation line 17 is displayed on the upper surface of the article part in the area, and the light emission area 17 extends from the side of the fish mounting plate 8 to at least the cutter 15 within the area. And The light emitting region 16 formed on the vertical plane may be formed by irradiating the laser light 18 from above the front of the fish head excision machine 1 as shown in the figure. The light is preferably colored light so that the irradiation line 17 can be easily seen.

Reference numeral 19 denotes a bucket for storing fish bodies, which is provided below the transfer end of the belt conveyor. However, depending on the case, a second belt conveyor may be provided instead of the bucket and the bucket may be transferred to the next fish processing step.

[Advantages of the Invention] The present invention is configured as described above, and is a fish moving belt in which a large number of fish placing trays 7 having both left and right edges of the first belt 5 open are fixed to the outer surface of the first belt. The conveyor 6 is provided, and the second belt 9 for pressing the fish is hung above the belt conveyor in parallel with the first belt so that the tensioned portions of the two belts facing each other can move in the same direction and at the same speed. Since the fish body placed on the dish is sandwiched between the belt conveyor and the second belt to be transferred, the fish body is dislocated from the dish 7 or displaced during the transfer. In addition, the cutter 15 is provided outside one side edge of the first belt 5, and the light emitting area 16 is provided on the vertical plane from the front part of the conveyor to the cutter along the side edge of the first belt on the side where the cutter is provided. , Each of which has its light emission area Since the irradiation line 17 is directly displayed on the upper surface, the irradiation line 17 displayed on the fish body indicates the cutter descending position as it is, and therefore the cutting at the fish head cutting planned position is the irradiation displayed on the fish body. It suffices to place the fish body on the plate 7 so that the line 17 is located at the position where the fish head is to be cut. Therefore, the fish head of the fish body is vertically above the mark displayed on the conveyor as in the above-mentioned conventional example. Since it is not necessary to judge whether or not the cutting position is located, it is possible to reduce the fatigue of the operator and to accurately cut the fish head at the planned cutting position, thus damaging the internal organs and degrading the quality of the fish body, Further, by removing the head excessively because of fear of deterioration in quality, it is possible to prevent deterioration in yield.
