JPH057440A - Apparatus for pulling float of round haul net - Google Patents

Abstract

PURPOSE:To effectively pull floats of a round haul net by rotatably attaching a supporting arm formed into an inverted Q shape to a trolley device movable on a rail provided on the broadside and oppositely installing rotating rollers having protrusions at the respective arm tips on the same axial center with a clearance. CONSTITUTION:A supporting arm 13 rotatably formed into an inverted Q shape is attached to a trolley device 4 movable on a rail 3 provided on the broadside. A rotating roller 20 in a truncated conical form, having rope reels 17 and 3 or more protrusions 16 is rotatably installed on one side of the supporting arm. A rotating roller in a truncated conical form having 3 or more protrusions 16 is oppositely attached to the other rotatably installed tip on the same axial center as that of the aforementioned roller with a clearance. Thereby, parts of floats 26 of a round haul net 24 are effectively pulled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traction device for a float of a lathe used for netting a lathe.

[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.

Especially, in the part where the float corresponding to the upper end of the lathe is attached, the float is rugged and difficult to fold, and the nets are continuously fed out from the net-sewing rollers that are hung up to a higher position. You have to be careful. In addition, because it is heavy, it often shakes greatly due to the swing of the ship, and it is dragged,
It is a very dangerous work such as being repelled.

For the purpose of saving labor and improving safety of the net-sorting work as described above, an automatic net-sorting device for a purse seine fishing boat has been invented, for example, in Japanese Patent No. 1086112, but the floating portion is still present. Currently, it is 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. A) A trolley device movably provided on a rail provided on the port side is provided with a swivel base rotatably provided around a rotation axis. B) Attach the link arm that is rotatable by the expansion and contraction of the cylinder to the bearing provided on the swivel base. C) Attach a reverse Ω type support arm to the upper end of the link arm. D) At one end of the support arm, a rotary roller having a truncated cone shape and having at least three protrusions on the surface is rotatably attached by a hydraulic motor, and a rope reel is provided at the base of the roller. E) The other end of the support arm is rotatably provided in the middle part by expansion and contraction of a hydraulic cylinder, and the tip of the arm has a truncated cone shape and a rotary roller having at least three protrusions on the surface, Install it so that it faces the same axis as the above-mentioned rotating roller. F) The gap between the rotating rollers is provided so that the upper end of the lathe can pass through. It is provided as described above.

1 is a front view of the present invention, and FIG. 2 is a central longitudinal sectional view. The trolley device 4 is movably mounted on a rail 3 formed by parallel pipes provided on a side wall 2 beside the screen 1.

In the trolley device 4, the rail 3 is supported by tapered wheels 5 provided inside, and a swivel base 8 is fixed to the upper end of a rotary shaft 7 attached to a bearing 6 provided at the front part.

The bearing 9 provided on the swivel base 8 includes a shaft 10
A link arm 12 is attached, which is rotatably provided by expanding and contracting the hydraulic cylinder 11 around.

On the upper end of the link arm 12, a support arm 13 formed in a reverse Ω shape is fixedly attached at the central portion.

A rotary roller 15 rotatably provided by a hydraulic motor 14 is attached to one end of the support arm 13.

The rotary roller 15 is formed into a truncated cone shape having a large diameter on the rear side and a smaller diameter on the front side, and three protrusions 16 are arranged evenly on the side surface of the tapered roller. A rope reel 17 is attached to the rear surface of the roller 15.

The other side of the support arm 13 has a shaft 18
Is provided so as to be rotatable by expanding and contracting the hydraulic cylinder 19, and the rotary roller 15 is provided at the tip of the arm 13.
In the same manner as above, the rotary roller 20 provided in the shape of a truncated cone and having at least three protrusions 16 on the surface is made to face the same axis as the rotary roller 15 and is rotatably attached by the hydraulic motor 14. is there.

Although the gap between the rotary rollers 15 and 20 is adjustable by expanding and contracting the hydraulic cylinder 19, it is possible to pass at least the upper end of the lathe even in the minimum state. It is as a structure.

FIG. 3 is an explanatory view showing a usage state of the present invention. A net 24 pulled up from the sea by a net hauler 22 and a netting roller 23 from the stern 21 side
Comes down on the mesh stand 1 from the meshing roller 23.

At this time, the gap between the rotating rollers 15 and 20 of the float pulling device 25 is widened so that the upper end of the net 24 is floated by the float 2.
When 6 is also passed through and then closed again, the part of the float 26 is caught between the rotating rollers 15 and 20.

When the float traction device 25 is rotated in this state, the float 26 is pulled by the projection 16 and is sequentially pulled. At this time, the net 24 covers the rollers 15 and 2 respectively.
It naturally falls from the gap between 0s.

[0019]

As described above, since the float is pulled by the pulling force of the rotating roller and sequentially drops, the person who works the mesh does not have to pull and support the float portion in this state. Since it is enough to fold and stack the floated part and the part of the net that falls naturally, the risk is very small and the work can be done with simple force, so the number of workers in charge is It is possible to reduce it.
