Description

The present invention relates to a lifting net auxiliary roller device used when a fishing net dropped in the sea is lifted by a lifting net provided at the tip of a tilting mast, and a lifting net method using the same.

Conventionally, the work of lifting a fishing net requires many workers, and is a heavy work, so the work is reduced significantly by automating the lifting net work and shortening working hours. A lifting machine and its operation method are disclosed (for example, refer to Patent Document 1).
By the way, for example, in an overseas purse seine fishing boat, in order to lower and stack a fishing net at a predetermined position of a net using a lifting net machine, a tilting mast attached to the tip is tilted. In addition, the fishing nets are spread from the bow side toward the stern side while being spread sequentially through the hoist of the hoist. Therefore, at the beginning of stacking, the tilting angle of the tilting mast with respect to the horizontal direction is maximized (indicated by a two-dot chain line in FIG. 1 for reference), and the tilting angle of the tilting mast is reduced as the fishing net approaches the stern side. (For reference, this is indicated by the solid line in FIG. 1).

Japanese Unexamined Patent Publication No. 2000-350535 (FIGS. 1 and 3)

However, the conventional lifting netting machine and the lifting netting method still have the following problems to be solved.
At the beginning of the lifting net work, the lifting net machine is at the highest position above the platform (for example, 15-18 m high), so during stormy operations, the fishing net is driven by strong winds (for example, wind speed 10-15 m / sec). Therefore, the work of spreading and arranging the fishing nets descending under the lifting machine is a heavy labor, and the work of stacking the fishing nets cannot be carried out smoothly, takes time, and in some cases can be a dangerous work. It was. Moreover, since the positions of the center of gravity of the lifting net and the tilting mast are increased, there is a problem that the stability of the ship is deteriorated.
It has been proposed to change the position of the lifting netting machine by providing a linear guiding mechanism that moves the lifting netting machine from the front part of the mast to the middle part, but the linear guide mechanism is attached to the front part of the tilting mast. However, there was a problem that the position of the center of gravity became high and the hull became unstable.
