Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a snap holding device for holding a snap attached to the end of a branch line in order to attach it to the main line in the tuna longline fishing method.

[Conventional technology and problems]

Traditionally, when attaching a snap to a main line thrown into the sea, a worker grasps the main line in one hand and attaches the snap to the main line in the other hand.

However, such manual snap-fitting work takes a long time, and there are concerns about injury.

In order to overcome these drawbacks of conventional manual work, the applicant has already proposed a snapping machine that automatically attaches the snap to the main line. The clamping hands are gradually attaching the clamped snaps to the main rope, which is under tension.

Incidentally, the snaps are conveyed by inserting their lower parts into recesses formed at intervals in the traveling direction on one side of the pitch conveyor that is driven intermittently, and the snapping hands grip the snaps in this state. However, if the gripping hand deviates from the predetermined position of the snap, the snap cannot be attached to the main rope.

However, the snaps are not always inserted into the recesses of the pitch conveyor so that they are in contact with the bottom of the recess, and sometimes the snaps are inserted away from the bottom of the recess. If the snap is spaced apart from the bottom of the recess, the position of the snap gripped by the gripping hand will shift, and there is a possibility that the snap cannot be attached to the main line.

[Purpose of invention]

In view of these points, it is an object of the present invention to provide a snap holding device that can always hold a predetermined portion of a snap.

[Summary of the idea]

The present invention comprises a pair of hand members disposed so as to be openable and closable, and a clamping hand that clamps a snap facing upward from a concave portion of a conveyor, and a clamping hand that is disposed above the clamping hand so as to be movable up and down, and that is used for the closing operation of the clamping hand. The present invention is characterized in that it has a positioning member that descends synchronously and pushes the upper end of the snap that the two hand members are trying to grip, thereby lowering the snap to a predetermined position.

[Example of idea]

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

FIGS. 1 and 2 show the tip of the snap attachment device, and a rotating body is supported on an elevating cylinder (not shown), and a telescopic cylinder is protruded from this rotating body. A substrate 1 is provided protrudingly from the tip. A cylinder 2 projecting laterally is provided on the base plate 1, and a piston 4 is disposed within a cylinder chamber 3 formed within the cylinder 2 so as to be movable in a horizontal direction. Note that the cylinder 2 is formed with a pair of ports 5A and 5B for supplying fluid pressure into the cylinder chamber 3. A piston rod 6 is protruded from the piston 4 and extends beyond the tip of the cylinder 2.

As shown in detail in FIG. 4, at the tip of the cylinder 2, a pair of brackets 7A, 8A, 7B, 8B are vertically spaced apart and protrude so as to be positioned on the left and right sides of the piston rod 6. A support pin 9A is bridged between the left pair of brackets 7A and 8A, and another support pin 9B is bridged between the right pair of brackets 7B and 8B. and,
These support pins 9A, 9B have a holding hand 1.
Base portions 12A and 12B of a pair of hand members 11A and 11B constituting 0 are rotatably pivoted. Further, a support pin 13 is protruded from the tip of the piston rod 6, and this support pin 13
The base end portions 14 of the hand members 11A and 11B are
A and 14B are supported. Therefore, by moving the piston rod 6 back and forth, both hand members 11A and 11B are opened and closed mutually. The hand members 11A, 11B have recesses 15A, 15B formed on mutually opposing sides for stably holding the middle portion of the snap S.

A support pin 16 is bridged between the pair of upper brackets 7A and 7B, as shown in detail in FIG. 17 base portions 18 are pivotally connected to each other so as to be swingable. Therefore, the positioning member 17 moves up and down with respect to the holding hand 10. As shown in FIG. 1, the lower surface of the positioning member 17 is formed with a receiving portion 19 having a semicircular arc cross section that abuts the upper surface of the snap S to lower the snap S to a predetermined position. On the other hand, a support pin 20 extending in the vertical direction is protruded from the middle part of the piston rod 6 on the outside of the cylinder 2, and a fork-shaped base end 21 of the positioning member 17 is attached to the support pin 20. Supported. Therefore, as the piston rod 6 moves back and forth, the positioning member 17 rotates and moves up and down. Note that when the piston rod 6 is retracted the most into the cylinder 2, the clamping hand 1
The position of the receiving portion 19 of the positioning member 17 is selected so that the receiving portion 19 of the positioning member 17 holds the snap S at a predetermined position.

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

Snap S is intermittently transported along with a branch rope with bait attached to the end for fishing at the tip.
They are inserted one by one into recesses formed in the pitch conveyor. With respect to such a snap S, the holding hand 10 which is in an expanded state is brought close to the snap S as shown by the chain line in FIG. When fluid pressure is supplied into the cylinder chamber 3 from the port 5A in this state, the piston rod 6 moves to the right in FIGS. Hold S. As the hand members 11A and 11B clamp the snap S, the positioning member 17, which is shown by the chain line in FIG. 1, rotates counterclockwise in FIG. 1 to the position shown by the solid line. Therefore, even if the lower end of the snap S does not reach the bottom of the pitch conveyor recess, the positioning member 17
Since the hand members 11A and 11B are in contact with the upper surface of the hand members 11B and are pushed downward, the portion of the snap S held between the hand members 11A and 11B is always kept at a predetermined position. As a result, the snap S can be stably attached to the main rope by the gripping hand 10.

[Effect of idea]

As explained above, the snap clamping device according to the present invention includes a pair of hand members arranged to be openable and closable, a clamping hand that clamps the snap facing upward from the recess of the conveyor, and The positioning member is arranged to be movable up and down and descends in synchronization with the closing operation of the clamping hand, and the above-mentioned two hand members push the upper end of the snap to be clamped, thereby lowering the snap to a predetermined position. The snap can be positioned by the positioning member when the snap is held by the holding hand, and therefore the snap can always be held at a predetermined position, and the snap can then be stably attached to the main line. It has the effect of being able to
