Description

[Detailed Description of the Invention] The present invention relates to 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 fishing in tuna longline fishing.

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 holds the snap in an upright position.

By the way, the snap 2 attached to the main rope 1
As shown in FIGS. 1 and 2, 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 securely grip the snap with the hands of the above-mentioned snap removal machine, it is necessary to raise the snap.

In view of these points, the present invention was made with the purpose of providing a snap erecting device that can reliably erect the snap attached to the main rope. A slit plate provided with a slit wide enough to prevent passage is provided on a rotatable lever, and the slit plate is moved between a position facing the running path of the main line and a position where it is retracted in the pulling direction of the main line. movable, and a cylinder device for rotating the lever is connected to the lever,
The snap is made to stand in close contact with the slit plate.

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

3 and 4 show the snap erecting device of the present invention, with a bracket 5 on the base 4.
A guide member 6 is provided to protrude through. This guide member 6 is shaped like a gutter having a bottom wall 7 and both side walls 8, 8, and the main rope 1 is guided along the bottom wall 7.
The guide member 6 faces the travel route of the main rope 1 so that the main rope 1 travels. The main rope 1 is designed to run from left to right in FIG. 3, and the distance between the side walls 8, 8 of the guide member 6 is such that it widens on the upstream side in the running direction of the main rope 1. There is.

A bell crank-shaped lever 10 that can rotate about a horizontal axis 9 is disposed within the base 4.
As shown in detail in B and C, a slit plate 11 having a vertical slit 12 formed at the middle position in the left-right direction of the upper end portion is attached.
By the rotation of the slit plate 11, the slit 12 faces the rear end side of the guide member 6.
In the pulling direction of the main rope 1, the reel 1 can take a position away from the running path of the main rope 1.

Details of the slit plate 11 are shown in FIGS. 5A, B, and C.
The width of the slit plate 12 is set to a size that allows the passage of the main rope 1 and prevents the passage of the snap. A round bar 13 having a U-shape in plan is protruded from the front surface of the slit plate 12 at a position corresponding to the lower end of the slit 12, so that it will not break even if the main rope 1 comes into contact with it. Further, a support plate 14 welded to the round bar 13 and the slit plate 12 is disposed inside the round bar 13, and is adapted to receive the snap 2. In addition, a pair of guide plates 15, 15, which also serve as reinforcement, are protruded from the slit plate 12 above the round bar 13 at intervals on the left and right.
designed to prevent falls. Furthermore, a reinforcing plate 16 is provided protruding from the slit plate 12 below the round bar 13.

Returning to FIG. 3, a pneumatic cylinder device 17 is installed on the side of the base 4, and a cylinder 18 of this pneumatic cylinder device 17 extends in the vertical direction, and its lower end is connected to the base. It is pivotally attached to a bracket 19 of the stand 4 by a pin 20 so as to be swingable. A piston rod 21 projects from the upper end of the cylinder 18, and the other end of the lever 10 is connected to the piston rod 21. Therefore, by applying pneumatic pressure to the pneumatic cylinder device 17, the lever 10 can take the forward position shown by the solid line in FIG. 3 and the retracted position shown by the chain line. The cylinder 18 is normally supplied with air pressure that urges the piston rod 21 in a direction to retract it, and can also be supplied with air pressure in a direction to pull out the piston rod 21 if necessary.

An engaging portion 22 is protruded from the lever 10 on the side where the piston rod 21 is connected, and when the lever 10 is rotated to the solid line position, the engaging portion 22 engages the damper 23 provided on the base 4. It is designed to prevent the generation of noise by coming into contact with the Further, an engaging portion 24 is provided protrudingly provided on the back of the slit plate 12 of the piston rod 21, and when the lever 10 is rotated to the chain line position, this engaging portion 24 is provided on the base 4. It comes into contact with an elastic member 25 such as rubber to prevent the generation of noise.

In addition, the slit plate 11 on the running route of the main rope 1
A hand 26 of a snap removing machine that grips the snap 2 is located above the snap holder.

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

Normally, the piston rod 21 is retracted into the cylinder 18 by the air pressure acting on the pneumatic cylinder device 19, the lever 10 takes the solid line position in FIG.
The vehicle is facing the driving route of Therefore, the main rope 1 passes through the slit 12. and,
When the snap 2 attached to the main rope 1 reaches the slit plate 11 from the guide member 6, since the snap 2 cannot pass through the slit 12 of the slit plate 11, it comes into contact with the front surface of the slit plate 11 and stands up. The hand 26 grips the snap 2 at the same time as the snap 2 is raised. And this hand 26
grips the snap 2, the pneumatic cylinder device 1
Air pressure is supplied to the cylinder 18 of No. 7, the piston rod 21 is extended, the lever 10 is rotated from the solid line position to the chain line position, and the slit plate 11 is retracted.
Therefore, there is no possibility that the slit plate 11 will obstruct the downward movement of the hand 26. In addition, since the round bar 13 comes into contact with the main rope 1 when the slit plate 11 etc. is rotated, there is no fear that the main rope 1 will be broken. After that, when the removal work of the snap 2 by the hand 26 is completed, the cylinder 1 of the pneumatic cylinder device 17 is
8 is supplied with air pressure, the piston rod 21 is retracted into the cylinder 18, and the lever 10 returns to the solid line position.

Note that the parts that cannot pass through the slit 12 of the slit plate 11, such as the knot of the main rope 1,
When it comes into contact with the slit plate 11, the slit plate 11 and the lever 10 rotate against the air pressure of the pneumatic cylinder device 17 due to the resistance, and take the retracted position shown by the chain line.

According to this embodiment, the snap 2 attached to the main rope 1 is raised up against the slit plate 11, so that the hand 19 of the snap removal machine
This allows the snap 2 to be reliably grasped and removed from the main rope 1.

As explained above, the snap erecting device according to the present invention has a slit plate provided with a slit having a width that allows the passage of the main line and prevents the passage of the snap, and that protrudes from a rotatable lever. The plate is movable between a position facing the travel path of the main rope and a position where it retreats in the direction of tension of the main rope, and a cylinder device is connected to the lever to rotate this lever, so that the snap is brought into contact with the slit plate. At the very least, the snap can be easily erected, and the snap removal machine can securely grip the snap, which is an excellent effect.
