Description

[Detailed Description of the Invention] The present invention relates to a snap removal machine for removing a clip to which a branch line is attached from the main line after fishing in tuna longline fishing.

In order to remove the snap from the mainline after tuna fishing, conventionally, the snaps were removed manually from the mainline that was being hoisted at high speed, or from the stationary mainline that had been wound onto the line hauler for hoisting the mainline. I was trying to remove it.

However, manually removing the snap from the main line that is being hoisted at high speed is dangerous and may cause injury, and it is difficult to remove the snap from the main line once it has been hoisted onto the line hauler. If the snap has been deformed after passing through the hoisting roller of the line hauler, or if the main line and branch line are entangled with each other, it may be difficult to remove the snap and separate the branch line from the main line. It becomes difficult.

In view of these points, the present invention was made with the purpose of providing a snap removal machine that can reliably remove the snap from the main rope. This device is provided with a V-roller for erecting the attached snap, and a gripping device movably arranged to grip the snap erected by the V-roller.

The present invention will be explained below with reference to embodiments shown in the drawings.

FIGS. 8A to 8F show the process of removing the snap 38 from the main line 37 using the snap removing machine according to the present invention. This snap 38
has the shape shown in Figure 9, and the branch rope 3
9 is connected to the proximal end 38a, and this proximal end 38
Two elongated members 38 that can swing around a as a fulcrum
It consists of b. The tip portions of the elongated member 38b are bent to each other so as to be able to grip the main rope 37, forming a head 38c for gripping the main rope 37. Such a snap shape is conventionally known and is described, for example, on page 102 of the Japanese Fishing Boat Encyclopedia (December 28, 1972, written by Toshito Tsuya, published by Seizando Shoten Co., Ltd.).

First, as shown in FIG. 8A, the piston rod 12 of the telescopic cylinder 11 of the gripping device 2 is extended to position the claw members 21A, 21B of the hand 13 above the V-roller 1. At this time, V roller 1
is rotating in the running direction of the main rope 37. By driving a line holer (not shown), the V of this V roller 1 is
The main rope 37 runs along the groove 1a, but as shown in Fig. 8B
As shown in the figure, when the snap 38 attached to the main rope 37 rides on the V groove 1a of the V roller 1, the V
The roller 1 stops its rotation, and both side walls of the V-groove 1a come into sliding contact with the snap 38.
will run in an upright position. This effect will be explained in more detail using FIG. 9. The main line 37 to which the snap 38 is attached is always under tension because it is pulled by the line hauler during hoisting.
Therefore, when the main rope 37 passes over the V-roller 1, the head 38c of the snap 38 is strongly pressed against the bottom of the V-roller 1 by the main rope 37. As a result, the head 38c of the snap 38 through which the main rope 37 is inserted comes into contact with the bottom of the V-roller 1, and the snap 38 itself becomes erect. Then, the snap 38 in the upright state is connected to the expanded claw members 21A of the hand 13,
When the tongue 29 contacts the contact surface 30 facing between the tongues 21B and 21B, the load of the main rope 37 running through the snap 38 acts on the contact surface 30, causing the tongue 29 to move backward. When pushed, the links 27A and 27B, which are connected by the tongue piece 29 and the pin 26, change from a straight state to a slightly bent state. Then, the claw members 21A and 21B, which were in the expanded state against the compression coil springs 25 due to the straight links 27A and 27B, are no longer connected to the compression coil springs 2.
5, both claw members 21A, 21B
is rapidly closed by the action of the compression coil spring 25, and the abutting surface 30 of the tongue 29 grips the snap 38 which is received therein.

Then, as shown in FIG. 8C, the hand 13 moves back about 35 degrees counterclockwise while gripping the snap 38 due to the drive of the swing motor 4 of the gripping device 2.
At that position, the swing motor 4 is lowered by driving the lifting cylinder 5, and the hand 13 is also lowered accordingly. Then, since an opening (not shown) is formed in the snap 38 held by the hand 13 by the grip of the hand 13, the snap 38 is opened by lowering the hand 13.
will be removed from the main rope 37.

Next, as shown in FIG. 8D, the telescopic cylinder 11 is driven to shorten the hand 13.
so that it cannot come into contact with the V-pulley 1, and drive the swing motor 4 to move the hand 13 clockwise approximately.
Rotate 125 degrees. Then, in this position, the piston rod 3 of the expansion cylinder 31 of the hand 13
Both links 27A, 27 are in a bent state with 2 extended.
Push B from the back to release the compression coil spring 25.
Both links 27A, 27B are brought into a straight state against the force, and both claw members 21A, 21B are separated. Then, the snap 38 held between the claw members 21A and 21B naturally falls and is stored in a predetermined snap receiver (not shown). In addition,
When both links 27A and 27B are brought into a straight state by the piston rod 32 of the expansion cylinder 31,
This piston rod 32 is shortened and both links 27
Make sure that A and 27B can be bent.

Thereafter, the swing motor 4 and the lifting cylinder 5 are driven to move the hand 1 as shown in FIG. 8E.
3 is raised and positioned opposite to the V roller 1. Further, in this position, the telescopic cylinder 11 is driven, so that the hand 13 faces above the V-roller 1, as shown in FIG. 8F, in preparation for the snap 38 that will travel next.

As described above, according to this embodiment, the snap 38 attached to the main line 37 can be automatically removed during high-speed hoisting, so damage to the snap 38 can be prevented.

The branch rope removed from the main rope 37 together with the snap 38 is wound onto a plant reel (not shown).

As explained above, the snap removal machine according to the present invention includes a V roller that faces the running position of the main rope and raises the snap attached to the main rope, and a device that can grip the snap that has been raised by the V roller. It has a movably arranged gripping device that allows the snap to be automatically and reliably removed from the mainline, without risking injury to the worker or damage to the snap. It has practical effects.
