Description

[Detailed description of the invention] This invention splits dried fish, especially dry sub-ice fish, Alaska pollock, etc., passes between a preload roller and a preload receiving roller, expands into a roughly V shape, and then is pressed in a drum-shaped manner. This invention relates to a dry fish butterfly opening device that spreads its wings like a butterfly by passing between a roller and a drum-shaped pressure roller.

Generally, after removing the head and internal organs, the animal is dried naturally or using a hot air dryer.

However, as ice fish and Alaska pollack dry, their entire bodies become wavy or curved, so they are shaped into straight shapes using shaping rollers, and then these ice fish and Alaska pollack are processed by hand (cottage industry). Then, they were torn apart using a specially shaped knife.
Several slices of torn ice fish, Alaska pollock, etc. are stacked on top of each other, then folded and pushed open like a butterfly.The pieces are then opened one by one and lined up for packaging.

Dried fish processed in this way is not productive and efficient because it is done manually, and the processing fee increases year by year, making it expensive.

In addition, since it is impossible to mass-produce it by hand, it becomes an expensive dried fish and is preventing its widespread use.

In addition, during manual processing, fish bones can cause injuries, which poses a safety problem.

The technical problem of this invention is that dry fish such as ice fish and pollack are automatically torn by a rotating cutter, and then the torn dry fish is automatically passed between two rollers. The reason is that it can be expanded and packaged immediately as it is.

The structure of the present invention, that is, the technical means for solving the above technical problem is as follows.

A rotary cutter fixed to a shaft held in a machine frame to tear the center of the dried fish between the running clamping belts in the direction of the fish axis, and a shaft arranged parallel to the shaft of the rotary cutter at a required interval. a preload roller attached to the shaft, a preload receiving roller attached to a shaft opposite to the lower side of the preload roller, a drum-shaped pressure roller attached parallel to the shaft of the preload roller, and the pressure roller. The dry fish butterfly opening machine consists of a drum-shaped pressure receiving roller attached to a shaft placed opposite to the bottom of the dry fish butterfly opening machine.

The above technical means works as follows.

The dry fish that travels while being held between the left and right holding belts has a splitting function in which the center is torn straight in the fish axis direction by a rotating cutter that can move up and down, and the open belly side of the torn dried fish is cut into an annular shape by a pressing roller. At the same time as it is pressed by the protruding part, it expands into a substantially V-shape while supporting the back side of the dried fish by the annular recess of the pressure-receiving roller disposed directly below the pressing roller, and then expands into a drum-shaped shape. It spreads between the pressure roller and the drum-shaped pressure roller, and then sends it out to the chute side, so a two-stage uniform pressing force is applied to the abdomen side and back side of the dry fish, and the butterfly with its wings spread. It is practical because one machine can have both the function of pushing the machine open.

In addition, the dried fish is simply fed between the clamping belts from the table and is automatically torn and opened, which increases production and reduces processing costs. The situation has improved further, which is good for business.

Next, a preferred example of the present invention will be described based on the drawings.

Reference numerals 10 and 10 denote left and right clamping belts that run while clamping dried fish. 11 is driven via worm gears 15, 15 of a shaft 14 whose one end is connected to a motor 13.
Rotate.

The preload receiving roller 18 is rotated via the gear 17 that meshes with the gear 16.

The preload receiving roller 18 and the preload roller 19 are driven via gears (not shown) on the motor 13 side.

20 is a shaft on which a drum-shaped pressure receiving roller 21 is inserted and fixed, and this shaft 20 is attached to frames 22, 2.
3 through bearings 24 and 25, and a gear 26 integrally formed with the pressure roller 21 is fixed to one end of the shaft 20.
And a chain sprocket 27 outside the frame 22.
are each locked.

The chain sprocket 27 is driven via a chain sprocket 29 fixed to one end of the shaft 28 of the preload receiving roller 18 and a chain 31 extending from a lower chain sprocket 30. A gear 32 meshing with a gear 26 formed integrally with the preload receiving roller 21 is formed integrally with a drum-shaped pressure roller 33 at one end of the preload receiving roller 21 and is fixed to a shaft 34 .

Both ends of the shaft 34 are provided with bearings 35 and 36 which are fitted into U-shaped grooves on the inner walls of the frames 22 and 23.
held through.

Directly connected to the shaft 34 on the drum-shaped pressure roller 33 side, the shaft 20 side of the drum-shaped pressure receiving roller 21 is connected via a bracket 38 to coil springs 37, 37.
are locked and fixed, so the drum-shaped pressure receiving roller 21 is always pulled downward, so that when the dry fish passes between the upper and lower rollers, the fish is in an open state. Alternatively, the pressure roller 33 is configured to be able to rise depending on the wall thickness.

Reference numeral 39 denotes a cutter drive motor, and a rotary cutter 44 is attached to the tip of a shaft 43 that rotates from the drive motor 39 via a pulley 40, a belt 41, and a pulley 42.

Reference numbers 45, 45 in the drawings are automatic centripetal rollers, 4
Numerals 6 and 46 are adjustment bolts for adjusting the positions of the guide pulleys 12 and 12, 47 is a table on which the dry fish 48 as the workpiece is placed, and 49 is a chute for discharging the expanded dry fish 48.

The effect will be explained.

The dry fish 48 running while being held between the left and right holding belts 10 is torn by the rotating cutter 44 and is also cut by the preload roller 19 and the preload receiving roller 1.
8, the dried fish 48 separated between the rotating preload receiving roller 18 and the preload roller 19 is pressed by the annular protrusion of the preload roller 19 on the open abdomen side, and at the same time is pressed by the annular recess of the preload receiving roller 18. The dried fish supported by the back side is fed into the V-shaped expanded state between the drum-shaped pressure roller 33 and the drum-shaped pressure receiving roller 21 in the next step.

The dry fish between the rollers 33 and 21 is further pressed from above and below, forming a flat shape like a butterfly spreading its wings.
Sent to the shoot side.
