Description

Detailed Description of the Invention

Industrial application fields

  The present invention relates to a net processing apparatus used for a fishing net fishing boat.

  In the purse seine fisheries, nets thrown into the sea for fishing are lifted from the stern of the net boat onto the deck using a lifting device such as a net holer or a net hoist, and the rear deck is handled by several workers. On top of the platform, the stacks are folded in order from the bow side to the stern side, and are taken in order.

  In these netting work, the net holer attached to the stern mentioned above, the netting device suspended at the tip of the derrick boom or marine crane, etc. are used. Most of the work is done manually by workers.

Problems to be solved by the invention

Action

In the use of the net processing apparatus in the present invention, the center of the roller frame, the separating arm and the horizontal roller is opened in the arrow A, and the net is introduced into the net processing apparatus.

  The part opened after the net enters the network processing device is closed by an arrow B to close the network processing device.

  The vertical roller of the port side float pulling device is raised in the direction of arrow C to guide the float, and the roller is lowered to arrow D to hold the float.

  Subsequently, similarly, the vertical roller of the starboard side sash pulling device is raised to introduce the sword portion, and the cover is lowered to hold the sword portion. This operation may be performed in the reverse order of the float part and the sink part or simultaneously.

  The center portion of the net is arranged almost evenly on the horizontal roller, and in that state, the horizontal roller is pressed by the presser roller, and the pulling device and the horizontal roller are rotated to start the netting operation.

  When the net is twisted and becomes a cocoon state, the net is twisted by raising the arm to the arrow F while extending the rolling arm to the arrow E, and at the same time, the entire net may be expanded to the left and right.

  If the net to be lifted is biased to either side, tilt the roller frame to the side opposite to the biased side, control the left and right rotation of the horizontal roller to slow the biased side, and rotate the lesser side faster good.

  The tension of the horizontal roller and the traction roller is generated by accelerating the rotation of the horizontal roller rather than the turning point of the traction roller of each traction device, preventing the twisting and entanglement of the net in the float and sink. Is possible.

  In the method of lifting the net while passing through a narrow gap between adjacent rollers as in the traction device, or the method of lifting the net while sandwiching the net, the relative rotational speed of the roller tip is different from the peripheral part. Since it differs from the central part, it is easy to cause a meshing or entrainment phenomenon.

  However, at this time, the tip of the roller can be flexibly expanded and contracted to easily pass the meshes and lumps of the net that are generated by the relative speed difference. To prevent.

  In other words, because the roller tip can slide freely, the tip of each roller slides in the direction in which it can operate even if it passes between rollers while the towing net is solid or twisted. Then, after passing through that portion, it returns to the normal state again, and the lifting net can be continued.

The invention's effect

  Since the net processing device is suspended at the tip of the bendable boom, it is possible to move the lifting net device back and forth by folding the boom according to the loading space of the net stand, and effectively It is possible to promote semi-automation in lifting net work such as loading work, which is extremely effective for labor saving and safety improvement.

  Furthermore, by moving the net processing device back and forth on rails attached to the left and right sides of the hull, the main body of the net processing device can be prevented from swinging, which can greatly contribute to safety work.
