Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for preventing catch from being caught in the hoisting drum when hoisting line of a line hauler, pole-and-line fishing machine, etc.

[Conventional technology]

In the pole-and-line fishing method for squid, for example, in the case of a small boat,
As shown in FIG.
1, and one machine can operate using four lines. In the figure, 22 is a winding drum for winding up the line 23, 24 is an engine room, and 25 is a fish hold.

When it is necessary to hoist the line, it is necessary to collect all the fishing equipment on board as the fishing grounds move, or when a squid gets hooked during fishing, the hoisting is entrusted to a line hauler and other There may be cases where adjustment work is required.

The most difficult point in squid fishing using a conventional line hauler fishing machine is that the hooked squid is pulled up by the take-up drum at a constant speed. The purpose is to prevent

Currently, line haulers are commercially available that operate an electromagnetic clutch when a squid is caught in order to prevent squid from getting caught in the line, but these have the problems of being complicated and expensive.

[Problem that the invention attempts to solve]

This invention solves these conventional problems and
It is an object of the present invention to provide an automatic guide line release device that can prevent squid from getting caught without using an expensive and complicated mechanism such as an electromagnetic clutch.

[Means for solving problems]

In the present invention, the distance between a pair of press-contact type winding drums for winding up the thread and the thread guide arm in front of the drum is narrower than the diameter of the eggplant ring attached to the thread, and the upper side is on the side of the winding drum. Two curved yarn handling arms are arranged facing toward the winding drum, and the base end of the yarn handling arms is centered on a spindle that is inclined at a required angle with respect to the direction perpendicular to the center of the thread. This is an automatic thread removal device that is fixed to a rotating plate that can be tilted to the side.

[Effect]

In the present invention, the thread is passed between a pair of press-contact type winding drums and the winding drum is driven, and when the thread is being wound up, when the place where the eggplant ring is provided comes to the thread handling arm, the eggplant ring cannot pass between the two thread handling arms,
The eggplant ring is caught between two thread handling arms.
On the other hand, since the yarn is wound up by the winding drum, the two yarn handling arms tend to lean toward the winding drum. The two yarn handling arms are fixed to a rotary plate that can tilt around a spindle tilted at a required angle, so that when the two yarn handling arms tilt toward the winding drum, they simultaneously move toward the outside of the winding drum. The movement increases as the inclination of the thread handling arm increases, and as the eggplant ring slips out of the upper end of the thread handling arm, the thread is finally removed from the winding drum. Therefore, even if the winding drum continues to rotate, the thread that was being wound by the winding drum comes off, and winding of that thread is stopped. The line tries to be returned overboard due to the weight of the catch, but the eggplant ring gets caught between the two line handling arms.
The path will not turn back any further.

As a result of the above, it is possible to prevent catch such as squid from being caught in the winding line without affecting the winding of other winding lines being wound up by the hoisting drum.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings. 1 and 2 are front and plan views of an embodiment of the device of the present invention. In these figures, 1 is the main body of the line hauler, 2 and 3 are a pair of press-contact hoisting drums, 4 is a guide arm, and 5 is a
1 is a thread handling arm, 6 is a guide roller, 7 is a thread, 8 is an eggplant ring, 9 is a sutte needle, 10 is a thread storage box, 11 is a rotary unit that attaches the base end of the thread handling arm 5 so that it can tilt freely. board, 12 is thread handling arm 5
It is a restoration spring.

In the present invention, as shown in detail in FIG. 3, the spindle of the rotating plate 11 of the thread handling arm 5 is inclined by θ with respect to the direction perpendicular to the threads. When the arm 5 is tilted toward the take-up drum 2, the tip of the arm 5 is deviated outward from the thread threading direction.

The operation of this embodiment will be explained below. The thread 7 passed between the two guide arms 4 and the thread handling arm 5 is wound up by the winding drums 2 and 3, and when the eggplant ring 8 comes, the eggplant ring 8 passes between the guide arms 4. It passes through and comes between the thread handling arms 5. Since the distance between the thread handling arms 5 is set narrower than the diameter of the eggplant ring 8, when the eggplant ring 8 is further wound up, the rotary plate 11 that fixes the thread handling arm 5 is tilted, and the third The thread handling arm 5 tilts as shown in the figure. During this tilting, the tip of the thread handling arm 5 shifts outward from the threading center of the thread 5, so the eggplant ring 8 moves along the space between the thread handling arms 5 to the upper part of the arm, and finally The guide yarn 5 is separated from the outer peripheral surface of the winding drum 2 to the outside.

When the eggplant ring 8 is removed from between the thread handling arms 5,
Since the thread handling arm 5 is no longer loaded, it returns to its original vertical position due to the restoring force of the restoring spring 12. On the other hand, the thread 7 which has lost its winding power tries to return to the sea, but at this time, as shown in Fig. 4, the eggplant ring 8 gets caught between the thread handling arms 5, It is possible to prevent the thread 7 from falling into the sea. After that, the winding drums 2 and 3 continue to rotate, and the other thread continues to be wound up by the other winding drums 2 and 3.

When the line hauler main body 1 is driven to operate, for example, four line threads by one electric motor, the above-mentioned automatic line removal device is provided for each of the winding drums 2 and 3. Therefore, even if one to three road threads come off each drum 2, 3 and the winding stops, it will not affect the winding of other road threads, so each sailor can carry out four windings by himself. can be operated sequentially and continuously.

[Effect of idea]

As described above, the present invention provides the following effects.

(1) Simply install a tilting thread handling arm;
It is possible to prevent squid and the like from being caught in the hoisting drum without requiring a complicated mechanism such as a conventional electromagnetic clutch.

(2) A pair of pressure-contact type winding drums are used as the winding drums, and the yarn is removed while the winding drums are rotating, so other winding drums driven by the same winding drum or the same drive source cannot be used. There is no effect on the winding of other threads being wound on the drum, and the original safe continuous operation can be made possible.

(3) When the thread comes off the hoisting drum, the eggplant ring catches it between the thread handling arms, preventing it from falling into the sea and keeping it in that state until the sailor starts operating the thread. .
