Description

  The present invention relates to an apparatus for automatically removing slime on a fish surface.

  A conventional fish slime removing device is disclosed in Patent Document 1. In this technology, the upper and lower belt conveyors that convey fish are provided so that the conveying direction is reversed, and the fish is inverted at the end position of the upper belt conveyor and transferred to the beginning of the lower belt conveyor. A plate is provided, and a rotating brush for scraping the slime is provided above each belt conveyor.

  According to this technology, while transporting fish in a horizontal position on the upper belt conveyor, the slime on one side is removed with a rotating brush, and the fish is reversed with a reversing plate and transferred to the lower belt conveyor. It is said that the fish on the other side can be removed with a rotating brush while the lower belt conveyor conveys the fish in a lying position.

  By the way, in the said technique, since the slime was removed one side at a time, there existed a problem that efficiency was bad and the apparatus enlarged. In addition, since the rotating brush is in a fixed position, depending on the size and outer shape of the fish, the hair tip may hit the surface too much and damage the surface, or may hit the surface weakly, resulting in insufficient removal of slime.

And pivotally supported at the tip of the cylinder 33a. In an unloaded state, the cylinders 33a and 33b are extended, the link plate 33c is raised to the uppermost position, and the left and right lower blades 33 are rotated in the approaching direction. When the fish F being conveyed comes into contact with the lower blade 33, the cylinders 33a and 33b contract and the left and right lower blades 33 rotate in the opening direction while descending. In FIG. 9, the upper blade 31 and the middle blade 32 are not shown.

  Hereinafter, the slime removal of the fish F will be described. When the operation panel 51 is operated to drive the front and rear conveying devices 20 and the fish F is raised and put into the insertion port 13 with the head facing forward, as shown in FIG. It is supported by the fish receiver 25, and both sides of the fish F are sandwiched between the belt surfaces of the left and right belt conveyors 21 and sent out.

  When the fish F comes into contact with the upper blade 31, the middle blade 32 and the lower blade 33, the fish F pushes the upper blade 31, the middle blade 32 and the lower blade 33 up and down and left and right by the feeding force of the belt conveyor 21, and moves backward. During the passage of the fish F, the blade tips of the upper blade 31, the middle blade 32, and the lower blade 33 are in contact with both surfaces of the fish F, and the slime is continuously scraped off. At this time, the upper blade 31, the middle blade 32, and the lower blade 33 freely move forward and backward by the expansion and contraction of the cylinders 31 b, 31 d, 32 a, 33 a, and 33 b according to the contour of the fish F, and the blade tip is always on the surface of the fish F. The slime is uniformly removed by contact with a certain force.

  The shapes of the upper blade 31, the middle blade 32, and the lower blade 33 do not completely match the cross-sectional outline of all the fishes F that are trying to remove slime, but the surface of the fish F has elasticity, so When the blade 31, the middle blade 32, and the lower blade 33 are in contact with each other, the surface of the fish F is slightly elastically deformed, and the blade tip is in wide contact with the surface of the fish F and is removed without leaving any waste. The back fin passes through the gap between the left and right upper blades 31 and does not interfere during conveyance. In addition, when watering means for applying water to the portion where the upper blade 31, the middle blade 32, and the lower blade 33 are in contact with each other during the removal of slime is provided, the scraped slime component is removed from the surface of the fish F, the upper blade 31, and the middle blade 32. And can be easily washed off from the lower blade 33.

  FIG. 11A shows the slime removal of the body of the fish F. Since the body portion has a large cross-sectional outer shape, the upper blade 31, the middle blade 32, and the lower blade 33 are greatly expanded vertically and horizontally. FIG. 11B shows the slime removal of the tail of fish F. Since the tail portion has a small cross-sectional outer shape, the upper blade 31, the middle blade 32, and the lower blade 33 are close to each other. As described above, the upper blade 31, the middle blade 32, and the lower blade 33 remove the slime on both sides at once while responding to the undulation of the outer shape of the passing fish F. The scraped slime component falls on the pan 40, and the fish F from which the slime has been removed is sent out by the belt conveyor 21 on the rear side and discharged from the discharge port 14.

  The technique of the present invention is useful for removing slime such as yellowtail and yellowtail, but can be applied to the removal of slimy fish by replacing the blade with a shape that follows the cross-sectional outline of the fish to be removed.
