Description

[Detailed Description of the Invention] The present invention relates to an intermediate stop device for a branch line winding device for tuna longline.

In tuna longline fishing, ropes called main lines are suspended in the sea using floats at predetermined intervals, and ropes with fishing hooks called branch lines are suspended from the main lines at predetermined intervals and can be removed. At the same time, the tuna caught on the branch ropes are removed and stored, and the branch ropes are wound up one by one and stored.

A winding drum rotated by an electric motor is used to wind up the branch rope.

It is equipped with a hydraulic pump driven by an electric motor, and guides the branch rope through a guide roller that is raised and lowered by the hydraulic pressure, so that the branch ropes adjacent to the surface of the winding drum are wound closely together. I'm guiding you.

If the branch rope itself becomes tangled while being wound up using such a branch rope winding device, the electric motor is temporarily stopped, and then the tangles are removed. The branch rope is unraveled, and the hydraulic motor is driven again to wind the branch rope.

However, when the electric motor is stopped, the hydraulic pump is stopped and no hydraulic pressure is supplied, and therefore no hydraulic pressure is supplied to the guide rollers that are raised and lowered by hydraulic pressure, causing the guide rollers to descend and rewind. Even if you start taking
The branch line winding restart position is lower than the winding stop position.
The branch ropes will be wrapped overlappingly throughout this shifted range.

FIG. 1 illustrates an example of a conventional branch rope winding device of this kind. In the figure, the reference numeral 1 indicates a starboard side plate, and at the top corner thereof there is a first plate for guiding a branch line 2. The guide roller 3 is horizontally suspended, and the horizontal part 1a at the top of the starboard side plate 1
A second guide roller 4 is vertically rotatably supported on the shaft.

Further, a pair of brackets 5 are fixed to the horizontal portion 1a of the starboard side plate 1, and a winding drum 7 is attached to the other end of these brackets 5 via a gear box 6.

The winding drum T consists of a plurality of pillars 7a separated from each other, and the outer peripheral surface of these pillars 7a becomes the winding surface of the branch rope 2,
In addition, the diameter of the circle inscribed in the distal end of each strut 7a is smaller than the diameter of the circle inscribed in the proximal end.

An electric motor 8 for driving is attached to the lower end of the gear box 6, a hydraulic cylinder 9 is fixed near one base of the bracket 5, and an elevating guide roller 11 is attached to the upper end of the rod 10. It is rotatably supported via a support frame 12.

As is clear from the plan view of FIG. 2, the elevating guide roller 11 is inclined at a predetermined angle with respect to the starboard side plate 1Vc so as to be perpendicular to the obliquely guided branch line 2.

The reference numeral 13 is an operation handle, which is used to control the winding drum 7.
Start and stop.

Reference numeral 14 denotes a hydraulic pump, which supplies hydraulic oil to the hydraulic cylinder 9IF through a pipe 15 and is driven by the electric motor 8.

As shown in FIG. 2, a hydraulic operating device 14a is provided at one end of the gear box 6, and this hydraulic operating device 14a is connected to a shaft 13a rotated by the operating handle 13 and fixed to the shaft end. It is operated by the rod 13b.

When winding up the branch rope 2 based on such a structure, the operating handle 13 is operated, the hydraulic operating device 14a is activated, the winding drum I is rotated, and the elevating guide roller 11 is raised at the same time.

The branch line 2 is then wound onto the winding drum I adjacently.

If a tangle 2a occurs in the middle of the branch line 2 during this winding, the operating handle 13 is operated to stop the hydraulic operating device 14a and the tangle 2a is loosened. falls, and as shown in FIG. 1, the branch line 2 becomes slack, and the position at which the winding is stopped and the position at which the winding is restarted are significantly different from each other.

As a result, even if the winding is restarted, the winding cannot be continued from the position at which the winding was stopped, and the windings end up being wound overlapping each other.

SUMMARY OF THE INVENTION An object of the present invention is to provide an intermediate stop device for a tuna longline branch line winding device configured to prevent a guide roller from descending even if the electric motor for winding the branch line winding drum stops.

Hereinafter, details of the present invention will be explained along with embodiments shown in the drawings.

FIG. 2 and subsequent figures illustrate one embodiment of the present invention, in which the same parts as in FIG. 1 are designated by the same reference numerals.

In this embodiment #lc, a guide shaft 16 is provided parallel to the rod 10 of the hydraulic cylinder 9.

The upper end of this guide shaft 16 is fixed to the support frame 12 of the elevating guide roller 11, and the middle part thereof is slidably fitted into a guide 17 fixed to the side surface of the hydraulic cylinder 9, as shown in FIG. There is.

The guide shaft 16 is of course formed into a cylindrical shape, and on its side surface there are ratchet teeth 18 arranged at a predetermined pitch on the same straight line.
are formed in large numbers.

On the other hand, a support plate 19 is attached to the bolt 2 on the inner surface of the bracket 5.
0, and a bearing plate 21 is fixed to this support plate 19 in a state where it is jointly fastened with a pin 20.

A support tube 22 is fixed to the bearing plate 21 at right angles, that is, while maintaining a horizontal state, passing through the bracket 5, and a rotary shaft 23 is rotatably supported in the support tube 22.

One end of the rotating shaft 23 has ratchet teeth 1 of the guide shaft 16.
A ratchet 24 having an acute angle that engages with the handle 8 is fixed, and a handle 27 is fixed to the other end via a boss 25 and a bolt 26.

The handle 27 is heavy and applies a rotational force to the rotating shaft 23 in a direction in which the ratchet 24 moves away from the ratchet teeth 18.

Next, the operation of this embodiment configured as above will be explained.

First, the operator operates the operating handle 13 to operate the hydraulic device 14a and rotate the winding drum I.

Then, the branch rope 2 is wound tightly adjacent to the winding drum I as the elevating guide roller 11 rises.

If the branch rope 2 becomes tangled during winding, the operating handle 13 is operated to stop the hydraulic operating device 14a, and at the same time the handle 27 is rotated to move the ratchet 24 to the guide shaft 16 (D/ Ffxt meshes with teeth 18.

Then, the rod 10 of the hydraulic cylinder 9 whose hydraulic oil was cut off
When the lowering is slightly lowered, the ratchet tooth 18
and ratchet 24 are completely engaged.

Since the length of the ratchet 24 is longer than the distance between the rotating shaft 23 and the valley of the ratchet teeth 18, the lowering of the guide shaft 16 is stopped, the lowering of the rod 10 is also stopped, and the elevating guide The roller 11 is held almost in its original position t-i=.

Therefore, even while untangling the tangle 2a, the upper end of the lifting guide roller 11 maintains the winding stop position as shown in FIG. 3, and even when winding is restarted, the branch rope 2 can be wound without overlapping. can.

By the way, when winding is restarted, hydraulic oil is supplied to the hydraulic pump 14 and at the same time, hydraulic oil is also supplied to the hydraulic cylinder 9, and the rod 10 starts to rise.

The ratchet 24 is therefore disengaged from the ratchet teeth 18.

At the same time, the ratchet 24 is rotated in the direction away from the ratchet teeth 18 by the weight of the handle 27, and the constraint relationship between the ratchet 24 and the ratchet teeth 18 is broken.
The rod 10 can be moved up and down freely.

As a result, the branch ropes 2 can be reliably wound in close contact with each other.

As is clear from the above description, according to the present invention, the elevating guide roller that guides the branch rope is configured so that it can maintain the branch rope guiding position when the winding drum is stopped. Even if the supply of hydraulic oil to the hydraulic cylinder for driving the lifting guide roller is cut off while the branch rope is being loosened, the lifting guide roller will not descend.

Therefore, even when winding of the branch ropes is restarted, the branch ropes do not overlap with respect to the winding drum, and the adjacent branch ropes can be reliably wound in close contact with each other.
