Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for uniformly winding seine fishing gear onto a take-up reel.

[Conventional technology and its issues]

In fishing boats that operate using seine nets, there is a method for winding the seine nets directly onto a reel. Broadly speaking, these methods can be divided into methods in which the boat is equipped with only a reel and the seine is evenly wound onto the reel by the ship's maneuvering, and a method for using seine fishing gear as shown in Japanese Patent Application Laid-open No. 56-51936. This method uses a winch.

The former is a simple device, but with this method, when the sea is dry or there are many other fishing boats around, it becomes difficult to maneuver the boat and it is difficult to wind the net evenly on the reel. There are problems such as the need for auxiliary work through input.

Further, in the latter method, although it is possible to move the seine to the center of the reel by means of a shift mechanism, it is impossible to move the seine from the center of the reel to the outside. For this reason, the net is not wound evenly on the reel, which causes excessive force to be applied to the net, causing the net fabric to tear.Also, because the net is wound unevenly on the reel, it is necessary to increase the winding capacity of the reel. This poses a problem in that equipment costs increase.

The purpose of the present invention was to solve the problems of the prior art by a simple yet rational means, and to provide a winding net that can uniformly wind up seine on a reel. The aim is to provide the equipment.

[Means to solve the problem]

The structure of the present invention, which solves the problems of the prior art, is that on the upper side of the reel for winding the seine fishing gear, in the direction of lifting the net,
A main net handling member E that can reciprocate over a required range along the axial direction of the reel, and a follower net handling member F that can be connected to and separated from the main net handling member E at an appropriate interval. Net sorting device D consisting of a set
is arranged.

〔Example〕 Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of the entire net lifting device, FIG. 2 is a perspective view of the main parts of the device of the present invention, and FIG. 3 is a partially omitted front view of the same main parts.

FIG. 1 shows a net lifting device (winch) A, which includes seine fishing gear, more specifically, seine fishing gear,
and a reel mechanism B for reeling seine fishing gear, a seine shift mechanism C for shifting seine lines left and right, and a seine shift mechanism C for shifting seine lines left and right, which is the object of the present invention, so that they are evenly wound onto the reel. Net shift mechanism D
It is composed of:

The reel mechanism B is constructed as follows. That is, a main shaft 2 is horizontally supported on a frame main body 1 mounted on the deck, and two take-up reels 3 and 4 are rotatably supported on the main shaft 2 and are pivoted close to each other. There is. And each take-up reel 3, 4
Large-diameter outer flanges 3a, 4a are provided on the outside.

The towline shift mechanism C is based on the above-mentioned Japanese Patent Application Laid-Open No. 1983-
Since it has the same structure as that disclosed in Publication No. 51936, a detailed explanation of the structure will be omitted. In the figure, 6 is a left and right frame, 7 is a drive shaft that is mounted like a bridge between the upper ends of the frame 6, and has forward and reverse feed spiral grooves (not shown) on the left and right sides with the center as a boundary, and 8 and 9 are drive shafts. A set of two guide rolls are provided to the drive shaft 7 and move symmetrically by the left and right forward and reverse feed spiral grooves, and a pull rope is interposed between the two guide rolls 8 and 9 to perform shifting. The reel is designed to wind the towline uniformly around the reel while rotating the reel.

The configuration of the seine shift mechanism D will be explained with reference to FIGS. 2 and 3. Reference numeral 12 denotes a pair of left and right frames erected on the deck with a width interval of the reel mechanism B on the upper side of the reel mechanism B in the net lifting direction. A drive shaft 14, which is rotatably driven by a shaft (omitted) and provided with a forward and reverse feed spiral groove 13 over a required length, is supported like a bridge and parallel to the take-up reel axis of the reel mechanism B. has been done. This drive shaft 14 includes a drive shaft 1
Pin 1 invaginated into forward/reverse feed spiral groove 13 provided in 4
Holder 16 with pin 5 and holder 17 without pin are inserted, and holder 1 with pin 15 is inserted.
6 is configured to reciprocate along the forward/reverse feed spiral groove 13 by the rotational drive of the drive shaft 14, and the holder 17, which does not have a pin, is loosely fitted onto the drive shaft 14.
It is designed to be able to move horizontally freely.

Note that the thickness of the net bundle varies depending on the type and configuration of seine fishing gear, so by making the rotation of the drive shaft 14 variable, the rotation of the drive shaft 14 can be adjusted according to the thickness of the net bundle. It is desirable to change the net fishing gear so that it can be wound evenly around the reel.

Although not particularly shown, the length of the drive shaft 14 and the shape of the forward/reverse feed spiral groove 13 are formed to be larger than the reel width, so that the drive shaft 14 can be used in conjunction with the variable speed action. It is also possible to wind the net fishing gear evenly by using the winding method.

Reference numeral 18 denotes a long guide groove that is provided on the deck parallel to the axis of the drive shaft 14 and has approximately the same length as the drive shaft 14.
Slide members 19 and 20 corresponding to 6 and 17 are recessed. And both the holders 16 and 17 mentioned above
Guide rolls 21 and 22 made of pipes, round bars, or the like are vertically installed between the slide members 19 and 20 corresponding to the slide members 19 and 20.

In addition, the holder 16 with the pin 15 and the corresponding slide member 19 have locking holes 23, respectively.
24 and a holder 17 without the other pin, and a corresponding slide member 20.
are provided with hook members 25 and 26 that engage with the locking holes 23 and 24. And, due to the structure of the holder 16 with the pin 15, the corresponding slide member 19, and the guide roll 21,
The main net sorting member E is configured, and also includes a holder 17 without a pin, and a corresponding slide member 2.
0. The structure of the guide roll 22 constitutes the follow-up net sorting member F. The seine shift mechanism D is configured as described above. Further, the connecting means for the main net sorting members E and F may be a connecting means other than the hook members 25 and 26, so that
It is not specific to the example means.

[Explanation of action]

The winding action of seine fishing gear will be explained using the above embodiment.

The draglines on both sides of the seine pulled up from the ship's slipway are moved by the dragline shift mechanism C shown in Figure 1.
While being sequentially unwound by the winding reels 3 and 4, the winding reels 3 and 4 are wound up in an orderly manner. When the seine has finished winding and the seine has come close to the reel mechanism B, both guide roll sets of the seine shift mechanism C are retracted to the left and right sides, and then the seine is freed as shown in Figure 3. The follow-up net sorting member F that moves to the main net sorting member E
While moving in the direction, the seine is sandwiched between both members E and F, and the hook member 25 of the follow-up net handling member F is
26 is fitted into and engaged with the locking hole 23 of the holder 16 of the main screen handling member E and the locking hole 24 of the slide member 19, thereby integrating both the screen handling members E and F. In this state, the drive shaft 14 is driven to rotate, and the main net handling member E is reciprocated to uniformly wind up the net along the width of the reel mechanism B.

[Effect of idea]

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Unlike the prior art, there is no damage to the net, and
Since there is no lopsided winding of the net, there is no need to increase the winding volume of the reel, and the reel device can be made more compact.

(b) There is no need to maneuver the vessel to deal with the movement of the vessel due to waves, etc., and the seine nets pulled up from the slipway are shifted while being held between a set of net handling members, regardless of the attitude of the vessel. Uniform winding can be achieved.

(c) Since the follower net sorting member is free from the drive shaft, it can be quickly evacuated to the side after use by hand, improving the work efficiency of seine fishing gear such as casting nets and hauling nets. can be improved.
