Description

[Detailed Description of the Invention] The present invention relates to a skin peeling machine for fish bodies such as Alaska pollack.

Generally, in order to skin a large number of fish bodies, first cut the fish body into three pieces using a fillet machine, remove the part with the back bone, and obtain two fillets with skin on one side. It is widely practiced to peel off the skin using a peeling machine.

Conventionally, this type of peeling machine has an edge roller rotatably disposed on the machine base, with its upper layer slightly protruding from the top surface of the phyto supply table, and the phyto peeling machine is placed between knives close to the upper layer. There is a known structure in which the fillet is fed downward while sliding into contact with the feed table, but the fillet machine described above cuts the fish body into three pieces and carries it out of the fillet machine with the skin facing upward. In order to process the phyto in the peeling machine, it is necessary to invert the phyto so that its skin is facing downwards before feeding it to the peeling machine. It is not possible to fully automatically perform the process of cutting the three pieces of skin and then peeling the skin in conjunction with This had the disadvantage that work efficiency was significantly reduced.

Further, the peeled skin adheres to the edge roller and is removed from the edge roller below the machine stand, but it is difficult to completely remove the peeled skin.

In order to eliminate these drawbacks, the present invention continuously supplies phyto on the belt conveyor with the skin facing upward, and the phyto is placed close to the top of the belt conveyor during its conveyance. To provide a fish body skinning machine characterized by being configured so that the skin can be peeled off at a high yield with a sharp edge roller and a knife, and the peeled skin can be instantly separated from the edge roller to perform continuous and automatic skinning.

The water is then rotated to the upper and lower water pipes 25.
．． It will erupt from 27.30.

In this state, if the phyto a of the fish cut into three pieces by the fillet machine is sequentially fed onto the belt conveyor 2,
Phyto-a is transported with its skin side facing upward,
When the edge roller 6 reaches the position, the edge roller 6 is forcibly pressed by the pressure roller 19 just before reaching the knife 13.
The knife 13 is forced into contact with the lower part of the front part of the knife and is held between the edge roller 6 and the belt conveyor 2, and the knife 13 instantly bites into the skin part.

By this knife 13, the skin of the phyto a is peeled off from the upper surface of the tip of the knife 13 and the edge roller 6 side, and is caught on the edge 6b' of the edge roller 6 and attached to the roller piece 6b of the edge roller 6, and the skin is peeled off. The phyto a passes through the knife 13 in an instant while slidingly contacting the lower surface thereof, and is conveyed rearward by the belt conveyor 2.

The peeled skin adheres to the roller piece 6b of the edge roller 6 and is sent forward from above by the rotation of the edge roller 6. At this time, the water jetted from the spout hole 27 provided at the rear of the lower water pipe 25 pushes the edge roller The jetted water is forced into the space 8 between the roller pieces 6b and 6b of the edge roller 6, and the pressure prevents the skin from adhering to the roller part 6a of the edge roller 6. The scraper piece 9b is reliably scooped up from the edge roller 6 by the scraper piece 9b of No. 9, and furthermore, the scraper piece 9b is
When the skin is pushed upward and separated from the edge roller 6, it is urged forward by the centrifugal force of the roller and is smoothly and instantaneously fed into the receiving tray 10.

As described above, in the present invention, a plurality of disk-shaped edge roller pieces 6b are arranged above the conveyor belt 2 at appropriate small intervals from the conveyance surface of the conveyor 2, and the central axis 6a is arranged at small intervals 6a.
An edge roller 6 fixed to a is rotatably arranged,
A comb-shaped scraper 9 inclined downward toward the front end is provided in front of the edge roller 6, and the rear end of each scraper 9 is inserted into the front part of the small space 6a between the edge roller pieces 6b, 6b. A knife 13 is disposed behind the scraper 6 so that its cutting edge is close to or in contact with the lower peripheral surface of the edge roller 6, and a water pipe 25 is disposed below the scraper 9 so that the spout holes 26 and 27 are connected to the edge roller 6. A leather catcher 10 is connected to the base end of the scraper 9, and a pressure roll 19 is pressed against the lower surface of the conveyor 2 below the edge roller 6. Since the present invention relates to a fish body skinning machine made of fish, the edge roller 6 and the knife 13 are disposed above the conveyor belt 2 to perform the skinning process with the phyto skin of the fish facing upward. Therefore, by continuously feeding the fillet carried out from the fillet machine onto the belt conveyor 2, it can be processed continuously and automatically without the need for manpower, and work efficiency can be significantly improved. Furthermore, when being conveyed to the edge loaf 6 position, the phyto a is reliably and forcibly pressed against the edge roller 6 by the pressing roller 19 that presses against the lower surface of the belt conveyor 2, and is held between the roller 6 and the belt conveyor 2. In this state, the knife 13 can bite into the skin along the underside of the phyto a, and while maintaining the biting state, the knife 13 can cut the skin into the knife 13 accurately by the pulling force generated by the progress of the belt conveyor 2. It is possible to instantly peel off the skin along its entire length with a good yield by pulling it out in the same direction.

Further, the peeled skin adheres to the edge roller 6, but the water jetted from the water pipe 25 toward the edge roller 6 makes it easy to remove it from the lodge roller 6, so that it can be surely removed by the scraper 9. Furthermore, this scraper 9 can also be pushed up by the water jetted from the water pipe 25 and smoothly fed into the tray 10 without causing it to come into close contact with the scraper 9, thereby eliminating the need for work due to adhesion of the skin to the edge roller 6 or scraper 9. This eliminates stoppages and enables continuous peeling.
