Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for pulling a spinner of a lathe, which is used when the lathe is lifted.

[0002]

2. Description of the Related Art In the purse seine fishery, nets thrown for catching are caught by using a net hauler and a derrick boom installed on the stern of the purse seiner or a net handling roller suspended on a marine crane. The fish are sequentially rolled up on the deck, and they are sequentially folded and arranged on the net stand provided on the rear deck by the hands of the workers, and are piled up and sorted, and ready for the next casting.

[0003]

However, in this work of net-sorting by the human power of the worker, in order to obtain the traction force for pulling up the net from the sea, the net finely squeezed by the rollers is manually forced. It is a very difficult labor to unfold and carefully fold it, and because the direction of lifting the net is on the port side of the stern, the hull is likely to lose its balance, so the worker's scaffolding is also unstable, and the work of meshing is performed. Making it difficult.

[0004] Among them, the part where the sinker, which is the lower end of the lathe, is attached, because the sinker is made of lead, it is very heavy and rugged and difficult to fold. From the meshing roller suspended at a higher position. Since the nets are unrolled one after another, you must be careful not to get crushed under the floor. In addition, since it is very heavy, it often swings greatly due to the swing of the ship, and at that time, it may be dragged or repelled, which is a very dangerous work.

For the purpose of labor saving and improvement of safety of the above net-sorting work, an automatic net-sorting device for a purse seine fishing boat has been invented, for example, in Japanese Patent No. 1086112. At present, the work is still supported by the hands of several workers. Therefore, the development of a mechanical device that effectively pulls the float portion of the net has been a challenge.

[0006]

The present invention has the following constitution in order to solve the above-mentioned problems. That is, a trolley device movably provided on a rail provided on the port side is provided with an arm portion capable of raising and lowering the main body about a vertical axis.

A hydraulic cylinder is attached to a clevis fitting provided on an arm portion having a valve box at the base portion, connected to a bearing of a trolley device, and the arm portion is attached so as to be lifted and lowered by expanding and contracting the cylinder.

A bearing is provided on the upper end of the arm portion so that a roller portion is rotatably attached. The roller portion is provided with a hydraulic motor on the rear surface of the roller support base, and is evenly arranged on the circumference on the front surface. A rotary roller having three protrusions is rotatably attached by the hydraulic motor.

A protective pipe is attached to the roller supporting base around the roller rear plate, and guide rods slightly protruding from the upper surface of the roller are inclined forward on both sides of the roller on the protective pipe. It is installed.

The gap between the rotary roller and the guide rods on both sides is provided so that the lower end of the lathe and the sinker mounting portion can pass through.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of the present invention, and FIG. 2 is a side view (partially sectional view). On a rail 2 installed in the front-rear direction on the port side 1 of the hull, a pipe portion 4 is supported by moving wheels 3 attached in two steps, and a trolley device 6 provided slidably by a pulley 5 provided inside. , The bearing 7 and the rod receiver 8 are mounted.

The bearing 7 has a valve box 9 at its base.
The arm portion 10 provided with is attached so that the entire arm portion 10 can be elevated about the elevation axis 11.

Clevis metal fitting 1 provided under the arm portion 10
1 is equipped with a hydraulic cylinder 12, and the cylinder 1
The rod fitting 13 of 2 is the rod holder 8 of the trolley device 6 described above.
, And the arm portion 10 can be lifted up and down by expanding and contracting the cylinder 12.

A bearing 14 is provided on the upper end of the arm portion 10, and the bearing 14 is pivotally attached by manually adjusting a stopper pin 15.

A roller support 17 is attached to the bearing 14 by means of a shaft 16, and the support 17 is attached manually so that it can be adjusted back and forth.

A hydraulic motor 18 is attached to the rear surface of the roller support 17, a front plate 19 is provided on the front surface and a rear plate 20 is provided on the rear surface, and three projections 21 are evenly arranged on the outer circumference of the roller. Tow roller 22 having
Is rotatably attached by the hydraulic motor 18 to form a roller portion 23.

A protective pipe 24 is attached to the roller supporting base 17 around the roller rear plate 20.
The protection pipe 24 has guide rods 25 on both sides of the roller 22 that slightly protrude from the roller front plate 19 from the upper side.
Is tilted forward and installed.

The gap between the traction roller 22 and the guide rods 25 on both sides is provided so that the lower end of the lathe can pass through.

FIG. 3 is an explanatory view showing a usage state of the present invention. A net 29 pulled up from the sea by a net hauler 27 and a net separating roller 28 from the stern side 26
Comes down on the mesh stand 30 from the meshing roller 28.

At this time, the lower end of the lathe 29 is passed together with the sinker 32 through the gap between the front plate 19 of the pulling roller 22 of the sinker pulling device 31 and the guide rod 25, and the pulling roller 22 is rotated as it is to project. Body 21 and protrusion 21
It will be in a state where the sinker mounting part is caught between.

When the sink pulling device 31 is rotated in this state, the sink 32 is pulled by the projection 21 and is sequentially pulled. At this time, the lower end portion of the pulled net 29 naturally falls from the gap between the front plate 19 and the guide rod 25.

[0022]

As described above, since the sinker is pulled by the pulling force of the pulling roller and sequentially falls, the person who works the mesh in this state must pull and support the very heavy sinker portion. However, since it is only necessary to fold the retracted sinker part and the part of the net that naturally falls and stack it, there is very little danger and the work can be done with simple force, so it is in charge It is also possible to reduce the number of workers involved.
