Description

[Detailed description of the invention] [Field of industrial application] The present invention is a snap erecting device used in a snap removal machine for removing a clip to which a branch line is attached from the main line after the end of fishing in tuna longline fishing. Regarding.

[Conventional technology and problems]

In order to remove the snaps from the mainline after tuna fishing, conventionally, the snaps have to be removed manually from the mainline that is being hoisted at high speed, or from the stationary mainline that has 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, a snap removing machine that can reliably remove the snap from the main line has been proposed, and this snap removing machine has a hand that maintains the snap in an upright position.

By the way, the snap 2 attached to the main rope 1
As shown in FIGS. 5 and 6, the connected branch ropes 3 are slanted so that their upper ends are pulled backwards with respect to the main rope 1 because they receive resistance from the seawater. Therefore, in order to reliably maintain the snap with the hand of the above-mentioned snap removal machine, it is necessary to raise the snap.

[Purpose of invention]

In view of these points, the present invention allows the snap attached to the main rope to be reliably erected.
Moreover, it is an object of the present invention to provide a snap erecting device that can easily deal with rope tangles.

[Summary of the idea]

The present invention provides a support frame that is movable up and down by a first cylinder device with respect to the base, and this support frame is provided with a slit having a width that allows the passage of the main rope and prevents the passage of the snap. The slit plate is movably arranged between a position facing the running path of the main rope and a position where it is retracted in the pulling direction of the main rope, and a second cylinder device is arranged to move the slit plate. .

[Example of idea]

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

FIG. 1 shows an embodiment of the present invention, in which a snap erecting device 10 has a base 11, and on the top of this base 11 there are two guide sleeves 12, 12 extending in the vertical direction. It is installed protrudingly. On the other hand, above the base 11, a support frame 13 that can move up and down with respect to the base 11 is provided, and the guide sleeves 12, 1 are mounted on this support frame 13.
Two rods 14, 1 are slidably inserted into 2.

It is designed to guide the ascent and descent of 3. Furthermore, a first cylinder device 15 is provided protrudingly on the bottom surface of the base 11, and this first cylinder device 1
The piston rod 16 of No. 5 is attached to the support frame 13.
Therefore, the support frame 13 is moved up and down with respect to the base 11 by driving the first cylinder device 15 . Note that a skirt member 17 is provided vertically at the lower end of the support frame 13 so as to be able to cover the lower part of the support frame 13.

At the front of the upper part of the support frame 13, as shown in detail in FIGS. 2 and 3, a bracket 18 is provided.
A guide member 19 is provided to protrude through. This guide member 19 includes a bottom wall 20, both side walls 21,
21, and has a support frame 1.
The guide member 19 can face the running route of the main rope 1 so that the main rope 1 runs along the bottom wall 20 when the main rope 3 is at the highest position. This main rope 1 is designed to run from left to right in FIG. 2, and the distance between both side walls 21, 21 of the guide member 19 is such that it widens on the upstream side in the running direction of the main rope 1. There is.

The support frame 13 has a bell crank-shaped lever 2 that can rotate about a horizontal axis 22.
3 is disposed, and a pedestal 24 is provided protruding from one end of this lever 23, as shown in FIG.
A support plate 26 is supported on the pedestal 24 by a support shaft 25 and is rotatable in the horizontal direction. A guide roller 28 is disposed on one side of the support plate 26 and is rotatable by a support shaft 27, and a vertical slit is provided in front of the support plate 26 at an intermediate position in the left-right direction of the upper end. 30 is formed on the slit plate 2
9 is installed. The extension line of the slit 30 of this slit plate 29 faces the guide member 19 and is located in the tangential direction of the guide roller 28.

Two brackets 31, 31 are hung in parallel on both sides of the lower end of the support frame 13,
A second cylinder device 33 is pivotally attached to the brackets 31, 31 by a pin 32. This second
A piston rod 34 of the cylinder device 33 extends upward and is pivotally connected to the other end of the lever 23. Therefore, the lever 23 is rotated by the drive of the second cylinder device 33, and the slit plate 29 is rotated.
The slit 30 can take a position facing the rear end side of the guide member 19 or a position where it retreats from the travel path of the main rope 1 in the direction in which the main rope 1 is pulled. The damper 35 that the lever 23 comes into contact with when the slit plate 29 is in the upright position, and the damper 36 that the pedestal 24 comes into contact with when the slit plate 29 is in the retracted position are connected to the inclination of the support frame 13. It is provided on the plate 37.

The width of the slit 30 of the slit plate 29 is set to a size that allows the passage of the main line 1 and prevents the passage of the snap 2. On the front surface of the slit plate 29 at a position corresponding to the lower end of the slit 30, a round bar 38 having a U-shape in plan is provided so as to protrude downward from the front, so that it will not break even if the main rope 1 comes into contact with it. It's summery. Further, a support plate 39 welded to the round bar 38 and the slit plate 29 is stretched inside the round bar 38, and is adapted to receive the snap 2. Further, a reinforcing rod 40 is installed between the slit plate 29 and the round bar 38.

In addition, the slit plate 29 on the running route of main rope 1
A hand 42 of a snap removing machine 41, which grips the snap 2, is facing above.

Next, the operation of the embodiment described above will be explained.

Under normal conditions, the fluid pressure acting on the first cylinder device 15 causes the piston rod 16 to extend upward, and the support frame 13 assumes a raised position relative to the base 11, while the fluid pressure acting on the second cylinder device 33 The piston rod 34 contracts, and as a result, the support frame 13 and the lever 23 move to the first position.
In the figure, the slit 30 of the slit plate 29 faces the running route of the main line 1, as shown by the solid line. Therefore, the main rope 1 passes through the slit 30. At this time, the guide roller 28 rotates following the extending direction of the main rope 1. When the snap 2 attached to the main rope 1 reaches the slit plate 29 from the guide member 19, the snap 2 cannot pass through the slit 30 of the slit plate 29, so it comes into contact with the front surface of the slit plate 29 and stands up. Ru. At the same time as this snap 2 stands up, the hand 42
grasp. When the hand 42 grips the snap 2, fluid pressure is supplied to the cylinder device 23, the piston rod 34 extends, and the lever 2
3 rotates from the solid line position to the chain line position, and the slit plate 29 retreats from the running path of the main rope 1. Therefore, there is no possibility that the slit plate 29 will hinder the downward movement of the hand 42. Note that when the slit plate 29 etc. is rotated, the round bar 38 comes into contact with the main rope 1, so
There is no risk that main rope 1 will break. Thereafter, when the removal operation of the snap 2 by the hand 42 is completed, fluid pressure is supplied to the cylinder device 33, the piston rod 34 contracts, and the lever 23 returns to the solid line position.

In addition, if the part of the branch rope 3 that is tangled with the main rope 1 is about to pass, the worker who is visually observing this will be able to
Fluid pressure is supplied to the cylinder device 15, and the piston rod 16 is contracted to move the support frame 13 into the first position.
Lower it to the position indicated by the chain line in the figure. Then, since the slit plate 29 is attached to this support frame 13, this support frame 13 also lowers.
The slit plate 29 is retracted from the travel path of the main rope 1, allowing the worker to untangle it in a sufficiently open space. Then, once the tangle is resolved, the support frame 13 can be returned to the solid line position in FIG. 1 using the first cylinder device 15.

According to this embodiment, the snap 2 attached to the trunk rope 1 is raised up against the slit plate 29, so the hand 42 of the snap removal machine 41 can securely grip the snap 2 and remove the trunk. It can be removed from the rope 1, and once the tangle between the main rope 1 and the branch rope 3 has passed, the slit plate 29 can be lowered together with the support frame 13 and the tangle can be disposed of in a wide space.

[Effect of idea]
