Can be prevented from falling downward, and more stable entrainment can be performed.
[0031]
Further, in the vicinity of the base end portion 28b of the rod portion 28, a U-shaped line regulating portion 32 is formed so as to protrude upward so as to straddle both sides of the V shape formed by the rod portion 28. The line upward restriction portion 32 can prevent the purse line 14 from being detached upward, and can perform more stable entrainment.
[0032]
Accordingly, the purse line 14 passes over the holding plate 30 via the tip 28a of the rod portion 28 and is wound on the three-way roller portion 22 side while being regulated by the line regulating portion 32. The parsing ring 13 attached to the parsing line 14 via the ring suspension rope 11 is sequentially passed through the rod portion 28 as shown in FIG. Can be automatically stored.
[0033]
A locked portion 33 that secures a reference position in the vertical direction of the rod portion 28 is formed at the base end portion of the rod portion 28 that is rotatably supported by the bracket 27. On the rotating arm 25 corresponding to 33, a locking portion 34 is formed for abutting and locking the locked portion 33. Therefore, the locking position of the rod portion 28 by the locked portion 33 and the locking portion 34 is the normal position in the vertical direction of the rod portion 28 during operation.
[0034]
In FIG. 1, the locking position of the rod portion 28 is a position rotated about 50 ° downward from the horizontal position indicated by the one-dot chain line in FIG. 1, but it is not necessary to be limited to this. Various values may be selected according to the design concept.
[0035]
Next, a turning net operating method using the ring holder according to the present invention to which the ring holder 16 is applied will be described.
[0036]
In the present embodiment, it is assumed that the ring holder 16 is fixed in the vicinity of the purse winch 47 installed on the hull port as shown in FIG.
[0037]
First, in the initial state, it is assumed that the rod portion 28 is held at the locking position by the locking portion 34 and the locked portion 33 and holds the initial position. Further, the rod portion 28 does not rotate in the horizontal direction at all, and as shown in FIG. 2, the rod portion 28 is positioned in a state where the longitudinal direction of the rod portion 28 and the axial direction of the lateral roller 23 are orthogonal to each other. To do. At this time, it is assumed that the fishing net 35 has not yet been thrown into the lathe 1.
[0038]
Furthermore, in the present embodiment, the lathe 37 shown in FIG. 7 is used from the viewpoint of reducing the weight of the lathe 37 and further reducing the personnel and cost required for operation. The swirl net 37 is formed in such a manner that the mesh 38 of the body net portion in a predetermined range on the major side is larger than the mesh 38 on the fish catch side excluding this range. The side end portion is connected to the position of the body net portion corresponding to the boundary between the body net portion in a predetermined range on the major side and the body net portion on the fish catching side.
[0039]
Next, when starting the throwing net from the initial state, as shown in FIG. 8, the resistor 40 is floated on the sea to secure a predetermined throwing net position, and the fishing boat 35 is advanced to circulate around the fish school 10. The lathe net 37 is fed out to the sea sequentially from the end on the fish catch side.
[0040]
When the fishing boat 35 goes around the fish school 10 and the bow reaches the position of the resistor 40, the movement of the fishing boat 35 is terminated, and the resistor 40 is taken in on the port side of the bow as shown in FIG.
[0041]
Thereafter, the standing net 41 arranged on the stern starboard brings the triangular net 42 attached to the fish catching side of the swirl net 37 close to the hull and connects it to the stopper hook 43.

And after completion | finish of the said throwing net | network, as shown in FIG. 10, the winding of the purse line 14 and the preparation of a lifting net are performed. That is, the major rope 46 is clamped by the ball roller 44 as the lifting net means disposed on the stern side.
[0043]
Further, the purse line 14 is pulled up from the tip 28 a of the rod portion 28 of the ring holder 16 to the position of the purse winch 47 installed on the hull port via the holding plate 30 and the three-way roller portion 22. Connected to the wound purse line main rope 48.
[0044]
Next, as shown in FIG. 11, the leading net is lifted by driving the ball roller 44 while winding the purse line 14 by driving the purse winch 47.
[0045]
At this time, the purse line 14 is held in a predetermined winding direction by the rod portion 28, the holding plate 30, the line restricting portion 32, and the three-way roller portion 22, so that the purse line 14 can be stably wound.
[0046]
In addition, since the purse line 14 is penetrated by the purse ring 13 connected to the lathe 37, the purse line 13 penetrated through the purse line 14 in turn with the rod part 28 as the purse line 14 is wound. It is accommodated so as to be penetrated by. For this reason, the purse ring 13 can be stored automatically and efficiently simultaneously with the winding of the purse line 14, and the personnel and power required for the ring winding work can be reduced.
[0047]
Furthermore, the winding direction of the purse line 14 is not always the direction in the initial state shown in FIG. 2, that is, the direction orthogonal to the longitudinal direction of the hull from the bow to the stern. There is a possibility of displacement from the initial state to the left and right in FIG.
[0048]
In such a case, since the rod portion 28 can be appropriately rotated left and right by the rotation arm 25, the purse line 14 can be properly wound in accordance with the position of the school of fish 10 and the like. The ring 13 can be stored properly. Further, since it is possible to prevent a large force from acting in the left-right direction perpendicular to the longitudinal direction of the rod portion 28 from acting on the rod portion 28, the ring holder 16 can be prevented from being broken.
[0049]
When the winding of the purse line 14 is completed, the rod part 28 of the ring holder 16 has a plurality of purse rings 13 engaged with the purse line 14 in the state adjacent to each other in the rod part 28. It is stored so as to penetrate.
[0050]
After the winding of the purse line 14 is completed, the rod portion 28 is rotated from an initial position (operation position) in the vertical direction to, for example, a position indicated by a two-dotted line in FIG. 1 (position at an elevation angle of 10 °). Ring winding is completed.
[0051]
Next, after the ring winding is completed, the fish catching side of the swirl net 37 raised to the hull port along with the purse line 14 is kept pulled up to the hull, and the stern side is used for fetching the fish in the next process. Migrate to At this time, it is necessary to feed out the purse line 14 to the stern side by rotating the purse winch 47 in a direction opposite to the rotation direction at the time of the entrainment as the turning net 37 moves to the stern side. In this case, since the rod portion 28 can be turned 90 ° from the initial state to the stern side as shown in FIG. 12 by the turning arm, the purse line 14 and the purse ring 13 penetrating the purse line are attached to the stern. It can be fed smoothly to the side.
[0052]
Therefore, according to the present embodiment, as the purse line 14 is caught, the purse ring 13 can be automatically accommodated by penetrating the rod portion 28, thereby reducing the manpower and cost required for ring winding. can do. Further, since the direction of the rod portion 28 can be changed by the support portion by the rotating arm 25 or the bracket 27, the properness of the purse ring 13 is determined according to the distance and direction of the fish school 10 when the purse line 14 is caught. Can be stored.
[0053]
Furthermore, it is possible to smoothly perform the preparation work for pumping the fish in the next process of the ring winding, thereby improving the efficiency of the entire operation.
[0054]
In addition, this invention is not limited to the thing of the said embodiment, A various change is possible as needed.
[0055]
For example, the present embodiment can exhibit a suitable effect even when applied to a lathe 1 having a conventional general configuration.
[0056]
