Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rope winding device for winding a branch rope and a pulling rope connected to the branch rope in order to draw a fish caught on a hook at the tip of the branch rope to a fishing boat in a longline fishing method such as tuna.

[0002]

[Prior art]

 In the longline fishing method, generally, a trunk line with a large number of branch lines, each of which has fishing baits attached to the fishing hooks at its tip, is attached at intervals to extend from the fishing boat into the sea and left for a predetermined time. Then, the tuna that migrates underwater catches on the hook to eat the bait. Therefore, while removing the branch rope, the trunk rope was pulled up to the fishing boat by the hoisting machine, and the branch rope of the fishing hook on which the tuna was caught was removed from the trunk rope and then connected to a pull rope of 100 to 300 m long. Depending on the resistance of the tuna, the branch line or the pulling line is manually pulled out or pulled in while pulling the branch line gradually and waiting for the tuna to weaken, and when the tuna weakens, it is pulled to the side of the fishing boat and pulled up to the fishing boat. Was doing.

However, when the pulling rope and the branch rope are manually pulled out or pulled in like this, it takes a lot of physical strength of the worker to pull one tuna into the fishing boat, and the harvesting efficiency is high. It was bad.

Therefore, conventionally, a branch line is connected to a pulling rope that is wound around a winding drum, and the winding drum is rotated in the feeding direction or the pulling direction of the rope according to the resistance of the tuna to pull the rope. Waiting for the tuna to weaken by pulling out and pulling in the ropes and branches, when the tuna weakened, it was moved to the side of the fishing boat and pulled up to the fishing boat.

By driving the take-up drum around which the pull rope is wound so that the tuna can be moved closer to the port side of the fishing boat, the worker's physical power is not consumed so much, so that the harvesting efficiency can be improved manually. Can be improved.

[0006]

[Problems to be solved by the device]

 By the way, in order to bring the tuna to the port side of the fishing boat by using the pull line that is wound around the winding drum as described above, it is necessary to connect the branch line to this pull line. To do this, one worker pulls up a considerable length of branch line so that it can be slackened on the fishing boat, and the other end of the branch line is taken up by another worker at the base of the branch line. The tip of the wound pull rope was connected by a clip.

When the branch rope is connected to the pull rope in this way, the branch rope that is slack on the fishing boat after the connection is not put into the sea once and then wound on the take-up drum from the pull rope. There was a possibility that the branch rope was entangled and could not be wound properly on the winding drum.

[0008] However, once the branch rope loosened on the fishing boat after being connected in this way is put into the sea once, the tension state of the branch rope is released, so that the tuna comes off the hook and the tuna swims relatively freely. There was a risk that the tuna would be cut by the screw of the fishing boat because it could be turned.

[0009] Furthermore, since the branch rope is wound up on the take-up rope take-up drum, the branch rope can be used next time after being taken out from the take-up drum into the sea. It had to be wound around, and the work was complicated.

The present invention overcomes the above-mentioned problems of the conventional ones, can connect a branch rope and a pulling rope without slackening the branch rope on a fishing boat, and further, when pulling a fish, the branch rope is connected. It is an object of the present invention to provide a rope winding device capable of winding a single rope in an orderly manner.

[0011]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the rope winding device of the present invention comprises a pulling rope winding portion and a branch rope which is connected in the axial direction of the pulling rope winding portion and wound up. A winding drum that has a branch rope winding part that can be separated and taken out and that rotates in both directions; and a pull rope and a branch rope that is connected to the tip of the pull rope from both ropes. When the load is within the range not exceeding the set value, and when it exceeds the set value, the draw-out and draw-out mechanism and the pull-in rope and the branch line drawn in by the draw-in and-out mechanism include the pull-in rope. And a traverse mechanism that reciprocates in the axial direction of the winding drum so that the branch rope is wound around the branch rope winding portion, and that guides the pulling rope and the branch rope. Is characterized.

[0012]

[Action]

 According to the rope winding device of the present invention having the above-described configuration, the branch rope of the fishing hook on which fish such as tuna is caught is removed from the trunk rope, and then the base end portion of the branch rope is pulled in by the feeding mechanism. The branch rope and the pulling rope are made into one rope by holding the branch rope and connecting the tip end of the pulling rope unwound from the winding portion of the winding drum to the base end of this branch rope. . When the load from the rope, which changes depending on the resistance of the fish, does not exceed the set value, the draw-out mechanism pulls in the branch rope or pulling rope and winds it on the take-up drum, and when it exceeds the set value. The branch line or the pulling line may be fed from the take-up drum, and the branch line may be gradually taken up on the take-up drum to bring the fish closer to the side of the fishing boat and pulled up.

On the other hand, regarding the pulling rope and the branch rope on the winding drum, the pulling rope is wound around the pulling rope winding portion of the winding drum by the action of the traverse mechanism, and the branch rope is changed to the winding drum. Since it is wound around the branch line winding section, the branch line can be taken out from the branch line winding section and used as it is next time as long as the puller rope and the branch line are separated.

[0014]

【Example】

 Hereinafter, the present invention will be described with reference to the embodiments shown in the drawings.

FIGS. 1 to 3 show the entire rope winding device according to the present invention. The rope winding device is installed on the deck of a longline fishing boat (not shown).

The rope winding device has a first housing 11 installed on a base 10, and inside the first housing 11, it projects upward as shown in detail in FIG. A motor 12 having an output shaft 13 is supported. The output shaft 13 is provided with a clutch 14 for cutting off the torque transmission of the motor 12 when the load is larger than a set value. A rotating shaft 15 extending upward is connected to the clutch 14, and the rotating shaft 15 is rotatably supported by a bearing member 16 attached to the first housing 11.

At the upper end of the rotary shaft 15, a take-up drum 17 whose axial direction is the vertical direction shown in FIGS. 1 to 3 is supported so as to rotate integrally with the rotary shaft 15. The winding drum 17 has a cylindrical lower part of the puller rope winding portion 18 in the lower half thereof. As shown in FIG. A pull rope RS is wound in advance toward the upper part. Above the puller rope winding portion 18, a truncated cone-shaped branch rope having a hollow inner portion whose lower end has the same diameter as the outer diameter of the puller rope winding portion 18 and gradually reduces the outer diameter toward the upper portion. The take-up portion 19 is continuously provided, and as shown in FIG. 5, the branch rope RB connected to the pulling rope RS is wound from the lower end portion to the upper portion thereof. It is supposed to be done. A plurality of slits 20, 20 ... That reach from the upper end to the lower end of the branch rope winding portion 19 are formed at intervals in the circumferential direction. Each slit 20 is for inserting the hand when removing the branch line RB from the branch line winding portion 19 and allowing the branch line RB to move upward.

On the side of the winding drum 17, there are provided a pull rope RS and a branch rope RB in which the base end of the branch rope RB is connected to the tip of the pull rope RS and integrated. A pulling rope RS and a traverse mechanism 21 for guiding the pulling rope RS and the branching rope RB to wind the branch rope RB so as to be located in the branch rope winding portion 19, respectively. There is.

The traverse mechanism 21 is located at substantially the same height as the rotary shaft 15 in parallel with the rotary shaft 15 and is rotatably supported by a bearing member 22 mounted on the first housing 11. It has a shaft 23. Sprockets 24 and 25 are fitted to the upper end of the rotary shaft 15 and the upper end of the rotary shaft 23, respectively, so as to rotate together, and a chain 26 is wound around the sprockets 24 and 25. The rotation of the rotating shaft 15 is transmitted to the rotating shaft 23.

At the upper end of the rotary shaft 23, a screw shaft 27, which is dimensioned so as to reach from the lower end to the upper end on the side of the winding drum 17, is attached so as to extend in the vertical direction. There is. A guide shaft 28 extending parallel to the screw shaft 27 is fixedly provided near the screw shaft 27 so as to be supported by the first housing 11.

A piece member 29 is fitted on the screw shaft 27 and the guide shaft 28 so as to be able to move back and forth along the shafts 27, 28. The piece member 29 has a through hole (not shown) in which the screw shaft 27 is loosely inserted and a through hole 30 in which the guide shaft 28 is inserted relatively densely. In addition, a driven member (not shown) having a ball protruding from it which can be fitted in a valley of a male screw (not shown) of the screw shaft 27 can be brought into contact with and separated from the screw shaft 27 in the piece member 29. It is arranged as follows. The driven member is urged by a coil spring (not shown) in a direction to be screwed into the male screw of the screw shaft 27. Furthermore, a T-shaped handle 31 protruding rearward is provided at the rear end of the driven member, and by pulling the handle 31 against the elastic force of the coil spring, the driven member is Is released from screwing with the screw shaft 27. By releasing the driven member from being screwed with the screw shaft 27, the piece member 29 can be moved in the axial direction of the screw shaft 27 without rotating the screw shaft 27.

A horizontal axis first guide roller 32 that guides a pulling rope RS or a branch rope RB from a pulling and feeding mechanism 34, which is described later, around the piece member 29, and from the first guide roller 32. And a second guide roller 33 which hangs the pulling rope RS or the branch rope RB and guides the winding for winding on the winding drum 17, respectively. Both of these guide rollers 32 and 33 similarly pull out the pulling rope RS or the branch rope RB when the pulling rope RS or the branch rope RB is fed from the winding drum 17 to the pull-in feeding mechanism 34. I will guide you. The movement of the bridge member 29 with the rotation of the screw shaft 27 is performed by the pulling rope RS on the pulling rope winding portion 18 of the winding drum 17 and the branch rope RB on the winding drum 1. The pitch of the male thread of the screw shaft 27 is set so that the male thread of each of the seven branch rope winding sections 19 is wound.

The pulling-out / feeding-out mechanism 34 has a second housing 35 installed on the base plate 10, and an end of the second housing 35 has a horizontally protruding output shaft (see FIG. A motor 36 having (not shown) is supported. A transmission shaft (not shown) extending in the second housing 35 is connected to the output shaft of the motor 36, and the end of the transmission shaft is connected to the motor 36 when the load is larger than a set value. A clutch (not shown) is installed to cut off torque transmission. The clutch drum 37 is connected to the output side of the clutch so as to be driven by the motor 36 after being decelerated via a pinion and a gear that mesh with each other.

The sandwiching drum 37 is composed of two drum halves 38A and 38B whose opposing surfaces are formed in a flat truncated cone shape, and both drum halves are substantially V-shaped. When the pulling rope RS or the branch rope RB is sandwiched between the annular slopes 39A, 39B of 38A, 38B, the pulling rope RS or the branch rope RB moves inward in the radial direction between the annular slopes 39A, 39B due to the tension. It is firmly sandwiched between the annular slopes 39A and 39B, and is conveyed as the drum halves 38A and 38B rotate. The one drum half body 38B can be brought into contact with and separated from the other drum half bodies 38A and 38B by an adjusting mechanism (not shown). As a result, the pulling rope RS or the branch rope RB holds the drum half. The strength of the load acting on 37 can be adjusted.

The pulling rope RS or the branch rope RB is guided to the second housing 35 near the holding drum 37 between the holding drum 37 and the first guide roller 32 of the traverse mechanism 21. A guide roller is rotatably attached.

Next, the operation of this embodiment having the above-mentioned configuration will be described.

A trunk rope (not shown) having a large number of branch ropes RB each provided with fishing baits attached to the fishing hooks at their tips at intervals is made to extend from the fishing boat into the sea, and after leaving for a predetermined time, the trunk rope is wound. For the branch line RB that holds the fishing hook on which the tuna is hooked by a barge, pull the base end of the branch line RB onto the ship after removing it from the trunk line, and then feed it out. Both of the piece member 29 of the traverse mechanism 21 which is wound around the holding drum 37 and the guide roller 40 of the traverse mechanism 21 and is positioned near the boundary between the pulling rope winding portion 18 and the branch rope winding portion 19 of the winding drum 17. While being wound around the guide rollers 32 and 33, the base end of the branch rope RB is pulled by the snap 41 (FIG. 5) of the take-up drum 17 and the pull-hand rope RS previously wound around the rope take-up portion 18. Connect to and pull rope R Make S and branch rope RB into one continuous rope.

Then, the motor 12 for rotating the winding drum 17 in the winding direction and the motor 36 for rotating the sandwiching drum 37 in the drawing direction of the pulling rope RS and the branch rope RB are respectively driven.

Then, in a state where the resistance of the tuna is not large, both the clutch 14 that transmits the torque of the motor 12 for the winding drum 17 and the clutch (not shown) that transmits the torque of the motor 36 for the sandwiching drum 37. The torque of the motors 12 and 36 is transmitted to the winding drum 17 and the holding drum 37. Therefore, the sandwiching drum 37 is rotationally driven to draw in the branch rope RB (or the pulling rope RS when the base end of the branch rope RB is also fed by the resistance of the tuna). At the same time, the winding drum 17 is driven to rotate, the screw shaft 27 of the traverse mechanism 21 is rotated, and the piece member 29 is lifted, so that the winding drum 17 winds the branch rope RB. The branch rope RB, which is rotated in the take-up direction and pulled in by the holding drum 37, is taken up on the branch take-up portion 19 of the take-up drum 17.

In this way, while the branch rope RB is wound around the branch rope winding portion 19 of the winding drum 17, the resistance of the tuna increases, and the clutch 14 for the winding drum 17 and the When the clutch (not shown) for the sandwiching drum 37 exceeds the set value, the torque of each motor 12, 36 is not transmitted to the winding drum 17 and the sandwiching drum 37 due to the action of both clutches. The winding drum 17 and the sandwiching drum 37 are in a freely rotating state. As a result, the branch rope RB is fed out by rotating the winding drum 17 and the holding drum 37 in the direction opposite to the winding direction by the resistance of the tuna. At this time, the screw shaft 27, the drive of which is transmitted by the winding drum 17 and the chain 26, rotates in the direction in which the piece member 29 is lowered, and the second guide roller 33 is wound around the winding drum 17. Since the rope RB or the pulling rope RS is always opposed to the height of the tip, the branch rope RB or the pulling rope RS can be stably delivered from the winding drum 17.

Then, in such a state, when the resistance of the tuna becomes small and the clutch 14 for the winding drum 17 and the clutch (not shown) for the holding drum 37 fall below a set value, the motor The torques 12 and 36 are transmitted to the winding drum 17, the screw shaft 27, and the sandwiching drum 37, and the branch rope RB or the pulling rope RS retracted by the sandwiching drum 37 is wound up on the winding drum 17 again. Go.

In this way, depending on the resistance of the tuna, the tuna gradually weakens as the branch rope RB or the pulling rope RS is pulled in or fed out repeatedly. Therefore, the branch of the winding drum 17 is gradually weakened. The length of the branch rope RB wound around the rope winding section 19 gradually increases, and finally the tuna can be brought closer to the port side of the fishing boat. Therefore, the tuna may be pulled up there.

On the other hand, regarding the pull rope RS and the branch rope RB on the winding drum 17, the pull rope RS is wound by the pull rope winding portion 18 of the winding drum 17 by the action of the traverse mechanism 21 and branches. Since the rope RB is wound around the branch rope winding portion 19 of the winding drum 17, it is only necessary to release the snap and separate the pulling rope RS and the branch rope RB from each other. The outer diameter of the portion 19 is made smaller toward the upper side, and moreover, since the branch rope winding portion 19 of the winding drum 17 is formed with a plurality of slits 20, any one of the slits 20 can be touched. The branch rope RB can be easily pulled out from the branch rope winding section 19 by inserting the above and lifting the branch rope RB upward from the lower end thereof. Further, in this state, the branch rope RB is gathered in a coil shape, and therefore can be directly used for the next use.

As described above, according to this embodiment, since the branch rope RB is connected to the pulling rope RS while the branch rope RB is retracted by the holding drum 37, the branch rope RB is loosened on the fishing boat. It is possible to connect the branch line RB and the pull line RS without the need. Therefore, there is no risk of the tuna coming off the hook or being cut by the screw of the fishing boat.

Further, since the branch rope RB extracted from the branch rope winding portion 19 of the winding drum 17 has a coil shape until then, it is not necessary to perform any special work and is ready for the next use. You can

It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made as necessary.

[0037]
