Description

Description: TECHNICAL FIELD The present invention relates to a device for uniformly winding dragnet fishing gear around a winding reel.

[Prior Art and its Problems] In fishing boats that operate using a dragnet, there is a means for directly winding the dragnet on a reel. This means is roughly classified into a ship equipped with only reels, a means for uniformly winding a dragnet on the reel by the operation of the ship, and a winch for dragnet fishing as disclosed in JP-A-56-51936. There was a means.

In the former, the device itself is simple, but with this method,
When the sea is frosted or there are many other fishing boats in the surroundings, it is difficult to operate the boat, it is difficult to wind the net evenly on reels, and there is a disadvantage that auxiliary work by manpower is required.

Further, in the latter of the prior art shown in FIGS. 13 to 15, more specifically, in the means by means of the device disclosed in Japanese Patent Laid-Open No. 56-51936, moving the dragnet to the center of the reel is a shift mechanism. However, it is impossible to move the reel from the center to the outside. For this reason, since the net is not wound evenly on the reel, an excessive force is applied to the net, causing the net to break, or as shown in FIG. However, it is necessary to increase the winding volume of the reel, which causes a problem that the equipment cost increases.

The object of the present invention was made in view of the above circumstances, and provides a device capable of uniformly winding reeling nets by solving the problems of the prior art by a simple and rational means. It is something to do.

[Means for Solving the Problems] The structure of the present invention for solving the problems of the prior art has the left and right ends independently and vertically on the upper side of the reel for winding dragnet fishing gears in the direction of the net. Alternatively, a meshing member movable in the front-back direction is provided.

This means that the take-up reel on the early side can be temporarily stopped, or the number of revolutions can be adjusted, or the reel on the early side can be temporarily stopped when the dragnets cannot be wound evenly on the left and right. It is designed to be wound evenly. The reel mechanism B is configured as described above.

Next, the shifter mechanism C for dragnets will be described with reference to FIGS. That is, the drive shaft 19 is horizontally mounted on the upper portion of the frame body 11 on the winding guide side of the dragnet.
A forward / reverse feed spiral groove 20 is provided in a range facing the width of the two take-up reels 9 and 10 of 19, and the both forward / reverse feed spiral grooves 20 have pins built in a holder 21 although not particularly shown. When the drive shaft 19 rotates in one direction, the pins pass through the spiral groove 20 and the shifter members 7 and 8 reciprocate along the drive shaft 19. Since this type of shifter mechanism is publicly known, detailed description thereof will be omitted, but it is desirable that the right and left can be driven separately.

On the lower side of the holder 21, two guide rolls 22 and 23 which are erected parallel to each other are provided at a required interval, that is, an interval through which the sequins can pass. , 2
The lower end of 3 is attached to another holder 24, and this holder 24 is connected to a guide rod 25 provided in parallel with the drive shaft 19.

Further, in the shifter mechanism C of the present invention, the guide rolls 23 located on the opposite sides, that is, inside, are not fixedly supported between the upper and lower holders 21 and 24,
The upper end of this inner guide roll 23 is the shaft fixed to it.
It is pivotally attached to the upper holder 21 by 26, and the lower end is engaged with the U-shaped groove 27 provided in the lower holder 23. And, this guide roll 23, as shown in FIGS. 14 and 15,
At the preparatory stage for winding the dragnets near the end of winding the dragnets, the shaft 26 is rotated about 90 ° upward to make it escape from the guide range of the dragnets. Therefore, the shifter mechanism C of the dragnet is configured as described above.

Next, the drag net shifter mechanism D is configured as follows. The shifter mechanism D is installed between the reel mechanism B and the shifter mechanism C of the dragnet as shown in FIGS. 3 and 4, but can be installed on the upper side of the shifter mechanism C. Therefore, the installation location is not limited to the illustrated position.

28 is a frame which is installed on the upper side of the reel mechanism B and which is vertically installed on the deck so as to face the deck with a space slightly larger than the width of the outer flanges 13 and 14 of the take-up reels 9 and 10. Vertical guide slots 29 are formed in each of them. A bearing member 30 is provided in each of the guide elongated holes 29 so as to be movable up and down, and a meshing roll 31 is provided between the bearing members 30.
Is bridged over. Then, the above-mentioned bearing members 30
Cylinders 32a and 32b for vertically moving the meshing roll 31 are respectively interposed between the outer end of the pedestal and the pedestal supporting the frame 28 or the deck. The shifter mechanism D of the dragnet is constructed as described above.

[Explanation of operation] After the net has been towed for a suitable time in the state shown in FIG. 1, the take-up device A is driven to perform the take-up net. In FIG. 13, the take-up reel 9 and the take-up reel 9 are shown in FIG. The state close to the end of the winding is shown, and 33 shown in the figure is a play wire,
Goes to the stern and connects the dragnet 2 and the hand rope 4 in order to remove it from the dragnet 2. The pulling net 2 is evenly wound in order on the left and right take-up reels 9 and 10 by the left and right movements of the guide rolls 22 and 23 of the shifter mechanism, and the inner side provided on the take-up reels 9 and 10, and The outer flanges 13 and 14 prevent the edges of the winding layer from collapsing.

Then, from the state shown in FIG. 13, continue to the left and right play wires.
33, the hand rope 4 is also wound around the take-up reels 9 and 10,
As shown in the figure, when the net body 6 is pulled close to the winding device A, the guide rolls 2 of the shifter mechanism C for pulling nets
After moving 2, 23 separately to the outer flange 13, 14 side ends of the take-up reels 9, 10, rotation of both take-up reels 9, 10, and
The rotation of the drive source 19 is stopped, the guide roll 23 of the shifter mechanism C is rotated upward, and the guide roll 23 is escaped out of the guide range of the drag nets, and both guide rolls are moved.
22 and 23 are located outside, and the shift action by the drive of the drive shaft 19 is stopped.

By the above, the winding of the dragnets is completed, and then the winding of the dragnets is started. The operation will be described with reference to FIGS. 6a, 6b and 6c. FIG. 6a shows a state in which the meshing roll 31 is set in the horizontal direction, and FIG. 6b shows the expansion / contraction action of the cylinders 32a, 32b. The state of being set diagonally so that the right side is the upper side, Fig. C is the expansion and contraction action of the cylinders 32a, 32b,
It shows a state in which the meshing roll 31 is obliquely set so that the left side of the drawing is the upper side.

In the case of Fig. A, the net does not move in either the left or right direction, but due to the movement of the ship 1 etc.
There is no guarantee that it will be wound as shown.

Therefore, when the net shifts, by setting either the right or left side of the net separating roll 31 as the upper position as shown in Fig. B, c, the net moves to the take-up reel while moving in the higher direction of the net separating roll 31. It is wound up. The reason for this can be explained by the Bekult diagram corresponding to the b and c diagrams. That is, R is a drag force against the tension of the drag nets, and the axial direction component F of the R netting roll 31 is the netting force, and this F is the force and direction in which the net moves. The mesh moves to the right in the drawing in FIG. b, and to the left in the drawing in c. Therefore, due to the tilting action of the meshing roll 31, the drag nets are uniformly wound on the winding reel.

Note that FIG. 7 shows an upper winding method in which the drag nets are wound from above the take-up reel through the lower side of the net drag roll 31, and FIG. It shows a lower winding method in which the winding reel is wound from the lower side through the upper side, and its adoption is arbitrary.

[Embodiment 2] (Figs. 9 and 10) Figs. 9 and 10 show a second embodiment. In this embodiment, the first embodiment is such that the left and right ends of the meshing roll are moved up and down by a cylinder. In contrast to the one in which the roll posture is moved horizontally, to the right, and to the left to shift the dragnets, the meshing roll 31a always maintains the horizontal state, and when viewed in plan, the axis line of the meshing roll 31a is changed. It is intended to shift the dragnets to the left and right depending on the posture parallel to the axes of the take-up reels 9 and 10 and the posture in which both axes intersect.

FIG. 9 is a plan view of the shifter mechanism E of the dragnet, and FIGS.
FIG. 7C is an explanatory flow diagram showing a shift of the network. The shifter mechanism E of FIG. 9 is configured as follows. That is, 34 is
A pedestal whose center is rotatably mounted on a deck by a shaft 35 and which is provided on the upper side of the take-up reel. On both ends of the pedestal 34, the outer flanges 13 of the take-up reel B, A frame (36) is hung vertically with a space slightly larger than the space (14), the meshing roll (31a) is mounted between the upper ends of the frame (36), and the pedestal (35) is provided between one end of the pedestal (34) and the deck. A cylinder 37 that rotates around the center is provided.

[Description of Action] The action of this embodiment will be described with reference to FIGS.
In the figure a in which the axis of the meshing roll 31a is parallel to the axis of the take-up reel due to the action of the cylinder 37, the net does not move in either the left or right direction, but due to the movement of the ship 1 etc. There is no guarantee that it will be wound up as shown in Figure a. Therefore, when the net shifts, by the action of the cylinder 37, one end of the net handling roll 31a is moved toward the take-up reel direction and the other end is separated as shown in FIG.
The net is wound on the take-up reel while moving in the direction closer to the take-up reel. The reason can be used by the Bekult diagram corresponding to the b and c views. That is, the axial component F of the mesh separating roll 31a with respect to the drag force R against the tension of the drag nets is the mesh separating force, and this F is the force and direction in which the mesh moves. Therefore, the drag nets are uniformly wound on the winding reel by the action of shifting the end of the meshing roll 31a in the front-rear direction.
Also, in this embodiment, similarly to the first embodiment, as shown in FIGS. 7 and 8, upper winding means and lower winding means can be arbitrarily adopted.

[Third Embodiment] (Figs. 11 and 12) This embodiment is a combination of the first and second embodiments described above. Fig. 11 is a front view of the shifter mechanism F,
This figure is a plan view of the same as above. In this embodiment, cylinders are connected to the left and right ends of the mesh separating roll of the second embodiment as in the first embodiment, and both ends of this mesh separating roll move up and down. It was made possible. Therefore, although details of the structure are omitted, in the figure, 34a is a pedestal, 35a is a shaft that rotatably supports this pedestal 34a with respect to the deck, 28a is a frame, 37a is a cylinder, 29a is a guide slot, and 30a is The bearing member 31b is a meshing roll. The shifter mechanism F is configured as described above.

[Explanation of Action] The action of the third embodiment is a combination of the shift actions shown in the first and second embodiments. That is, when the axes of the meshing roll 31b are parallel to each other when viewed from the front and the plane, the mesh is shown in FIG.
As shown in FIG. 10A, the film is wound without moving in either the left or right direction. Further, as shown in FIGS. 6b and 10c, by taking the posture of the meshing roll 31b, the net moves to the right side of the drawing, and also in FIGS. 6c and 10b. By taking the posture of the net handling roll 31b in this way, the net is moved to the left in the drawing.

[Effects of the Invention] According to the configuration of the present invention as described above, the following effects can be obtained.

(A) As in the prior art, since the net is not damaged and the net is not wound side by side, it is not necessary to increase the reel winding volume, and the size can be reduced.

(B) Up and down of the left and right ends of the meshing member (roll) and /
Or, the net can be moved smoothly in the shift direction only by shifting in the front-back direction, the structure is simple, and the efficiency of winding processing of the dragnet can be improved, which in turn increases the fishing efficiency of the dragnet. Therefore, the fishing efficiency can be improved.
