DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
1 is that the shaft center of the shaft portion main body 52 and the shaft center CL of the insertion portion 53 at the front portion are coaxial, and the insertion portion 53 is formed by thinning the distal end portion of the shaft member having a predetermined diameter, and the rear end portion of the distal end portion is formed. The locking piece 54 is provided so as to be bent backward and upward. When the juvenile cultivated scallop is locked to the rope by using the locking device 51, there are the following inconveniences. That is, as shown in FIG. 8, the scallops 61 and 62 are arranged on the left and right of the rope 63, and the ears 61a of the scallop 61, the predetermined portion 63a of the rope 63, and the ears 62a of the scallop 62 are arranged in this order by the drill 64. Locking holes 61b, 63b, 62b
To drill.

At present, this work is automated by an automatic machine. In this way, one scallop 61
From the above, the rope 63 and the scallop 62 are drilled in this order by the drill 64 with an automatic machine or the like. After punching, the locking tool 51 is inserted into the locking hole 62b from the side of the scallop 62 on the opposite side so that the insertion portion 53 at the tip end thereof comes first. This state is also shown in FIG. The locking tool 51 is inserted and set in the scallop 61, the rope 63, and the scallop 62 by an automatic machine or the like.

Specifically, the rear portion (base portion) of the locking tool 51 is picked up by a clamp or the like of an automatic machine (not shown), and the scallop 62 is
The insertion portion 53 at the tip of the locking tool 51 is passed through the hole locking 62b. Then, the insertion portion 53 of the locking tool 51 is passed through the locking holes 63b of the ropes 63 that are parallel to and adjacent to the scallop 62. After that, the locking hole 6 of the scallop 61 adjacent to the outside thereof
The insertion portion 53 is sequentially passed through 1b. The locking piece 54 has the locking hole 6
When passing 1b, the locking piece 54 releases the restraint by the locking hole 61b. The locking piece 53, which has been released from the restraint by the locking hole 61b, stands up and faces the outside of the locking hole 61b, and the locking piece 53 is hooked on the outer peripheral portion of the locking hole 61b and locked, so that the locking shell 61 is removed from the scallop 61. Stop escaping, scallop 6
1 to the rope 63. On the other hand, at the rear end of the shaft body 52 of the locking tool 51 that has already passed through the locking tool 51, a separate locking part is provided to prevent the other scallop 62 from slipping out of the locking tool 51. Scallops 61 and 62 on the left and right of the rope 63
Will be locked and held via the locking tool 51.

As described above, the locking tool 51 is attached to the scallop 62.
When the locking piece 54 is inserted into the locking hole 62b of the
When it enters 2b, the locking piece 5 stands up so that it tilts backward and upward.
No. 4 bends by contracting and sliding down the hole 62b. By this reaction, the insertion portion 53 at the tip portion is bent back upward. Since the axial center CL of the insertion portion 53 and the axial center CL of the shaft portion main body are coaxial, a locking hole 62 of the scallop 62 is provided.
When it passes b, it turns upward. By the way, rope 6
Since 3 is a knitted body of fibers, the inner periphery of the locking hole 63b is a roughened surface as shown in the drawing, and the fiber is broken and protrudes to the inner peripheral surface of the locking hole 63b. .

On the other hand, the locking hole 63b of the rope 63 is bored at the same level as the locking hole 62b on the upstream side of the insertion side of the locking tool 51, and therefore the fiber breaking portion is exposed. The tip portion 5 of the insertion portion 53 of the locking tool 51 is inserted into the stop hole 62b.
When 3a enters, since the tip portion 53a is bent upward, it is caught on the inner surface of the locking hole 63b of the rope 63, and the insertion portion 53 of the locking tool 51 can be inserted into and passed through the locking hole 63b of the rope 63. It is difficult to do it smoothly. As a result, from the state of FIG. 9, the rope 63 is pressed rightward in the figure to bend,
The positioning of the scallop 61 on the downstream side with the locking hole 61b may be hindered. Alternatively, as shown by an imaginary line a in FIG. 9, it may be bitten in the locking hole 63b to incompletely insert the locking tool 51. The above work is often automated by an automatic machine to save labor, and the work of setting the locking device on the scallop and rope becomes incomplete, causing a failure of the automatic machine and stopping the work. However, it causes inconvenience in the work because it causes frequent inspection work. In addition to the above, if you try to force the locking tool to pass through the hole of the rope, the locking tool will be damaged, and the locking tool will be wasted, which is also economically undesirable. There is also the inconvenience.

The present invention has been made to solve such problems. As described above, the object of the present invention is to arrange the scallops on the left and right (when the ropes are arranged horizontally, arrange the scallops on the top and bottom, or on the left and right) as described above, and use an automatic machine to respectively When piercing the holes coaxially and then inserting the locking device with an automatic machine in the order of scallop, rope, and scallop, the automatic insertion of the locking device can be performed smoothly, easily, and reliably. It is possible to smoothly, easily, and reliably perform the locking and holding of the work, improve workability, and eliminate wasteful maintenance work, thereby improving work efficiency and rationalization. Further, waste such as breakage of the locking tool is eliminated.
As a whole, the work efficiency can be improved, and economically advantageous work and locking tools can be used.

[0009]

[Means for Solving the Problems] Means for solving the above-mentioned problems are as follows: the center of the shaft portion of the insertion shaft portion at the tip of the locking portion provided at the front portion of the shaft body of the locking tool, A locking tool for scallop aquaculture, in which the phase is shifted so as to be biased in the direction opposite to the locking piece outward in the radial direction with respect to the center of the shaft of the main body. Further, the bottom surface of the insertion shaft portion of the locking portion and the bottom surface of the shaft portion main body have the same continuous surface, and the insertion shaft portion of the distal end portion of the locking portion has an outer diameter gradually decreasing in the direction of the distal end portion. It forms a substantially spear shape, and the phase of the shaft portion of the substantially spear-shaped insertion shaft portion is displaced radially outward with respect to the center of the shaft portion main body in a direction opposite to the locking piece. And a large-diameter shaft portion at the rear portion of the shaft portion main body to form a rear locking portion, which is a locking tool for scallop cultivation.

[0010]

According to the above means, the axial center of the insertion portion of the distal end portion is biased outward with respect to the axial center of the shaft portion main body of the locking tool and in the direction opposite to the locking piece, and the phase shifts. . Therefore, when inserting the insertion part of the locking tool into the locking hole of the scallop on the upstream side that is inserted into the locking hole of the rope, the locking hole and the locking piece interfere, and the tip of the insertion part reacts with each other. Even if it faces upward, the axial center of the insertion portion is biased downward, so the insertion portion bends upward from this downward facing axial center, and the inner circumference of the locking hole of the adjacent coaxially arranged ropes Bending does not occur while it interferes with the parts. Therefore, the approximate center of the rope locking hole,
The insertion portion of the locking tool passes through, and the insertion section passes through the locking hole of the rope without contact of the locking tool insertion section with the inner peripheral portion of the rope hole locking hole. Therefore, in the order of the upstream scallop locking hole, the adjacent rope locking hole, and the downstream scallop locking hole, the locking tool can smoothly and easily pass these locking holes. .

Fig. 7 is an explanatory view showing a state in which the scallop is locked on the scallop and the scallop is cultivated. Fig. 7 is an enlarged view of the tip of the conventional locking device. Fig. 8 shows the scallop, perforating the rope, and inserting the conventional locking device. 9A and 9B are explanatory diagrams for pointing out a problem that occurs when a conventional locking tool is inserted into a rope.

In FIG. 1, reference numeral 1 denotes a locking tool, and the locking tool 1
Is made of resin or the like, and includes an elongated shaft body 2. At the rear end of the shaft body 2, a large diameter rear locking portion 3 is provided.
It is formed to have a predetermined length in the axial direction, and a neck portion 4 having a small diameter is formed at a boundary between the shaft body 2 and the rear locking portion 3, and the neck portion 4 forms the shaft body 2 and the rear locking portion 3 at the neck portion 4. And are continuous.

An insert portion 5 is formed at the front end of the shaft main body 2 so that the diameter of the distal end portion is successively reduced. Insertion part 5
In the embodiment, the upper end of the tip is inclined downward, the distal end portion 5a is arcuate downward, and the lower surface 5b of the insertion portion 5 is
It forms the same surface as the lower surface 2b of the shaft body 2 continuously. Then, the shaft center CL ₂ of the insertion portion 5 is displaced from the shaft center CL ₁ of the shaft body 2 in the radial direction to the lower side in the figure, opposite to the protruding direction of the locking piece 6 described later. Set to. That is, with respect to the axial portion center CL ₁ of the shaft main body 2, shank center CL ₂ of the insertion portion 5, the locking piece 6 is set Shifts caused the phase to the opposite side. For example, when the diameter of the shaft body is D, this phase shift causes the shaft center CL ₂ of the insertion portion 5 to shift about 3 / 8D with respect to the shaft center CL ₁ .

A locking piece 6 is provided so as to be inclined rearward and upward at the front portion of the shaft body 2 and at the rear portion of the insertion portion 5 described above. The locking piece 6 is formed so that the rear end portion 6a is curved and slightly inclined rearward and upward, and is inclined frontward and downward toward the front portion. The locking piece 6 has a notch 7 so that the upper half portion between the front end portion 2c of the shaft body 2 and the rear end portion 5c of the insertion portion 5 is inclined forward and downward in the axial direction.
Then, the upper piece of the cutout portion 7 is formed by inclining and bending rearward and upward. The locking piece 6 and the insertion portion 5 described above constitute a locking portion 8, and the shaft body 2, the rear locking portion 3, and the front locking portion 8 are all integrally molded of resin or the like.

As shown in FIG. 3, the above-described locking tool 1 is formed as a multi-molded plate 11 in which both ends are connected by connecting plates 9 and 10 and a large number are simultaneously molded. Therefore, as shown in FIG. 3, a large number of locking tools 1, ... Are continuously provided in a vertical direction between the left and right connecting plates 9 and 10 and are supplied, and the left and right connecting plates 9 and 10 are connected by an automatic machine or the like. , The front and rear ends of the locking tool 1 ... Are separated and removed to obtain the locking tool 1 alone as shown in FIG.

The locking and holding of the scallop on the rope by the locking tool 1 will be described with reference to FIG. As shown in FIG. 4, similarly to the above, the rope 12 is sandwiched between the left and right sides (when the ropes are arranged horizontally, the scallops are arranged vertically or horizontally).
The scallops 13 and 14 are arranged on the scallops 13 and 14 and the drill holes 13a and 14a of the scallops 13 and 14 and the predetermined holes 12a of the rope 12 are engaged with the locking holes 13b and 12b in the same manner as above.
14b is coaxially drilled. After that, for example, in the locking hole 13b formed in the ear portion 13a of the right scallop 13, the locking tool 1
The tip portion 5a of the insertion portion 5 at the tip of is inserted and the locking portion 8 is inserted in the rope direction.

The insertion part 5 of the locking tool 1 is inserted into the locking hole 13b, slides in the locking hole 13b, and the tip of the insertion part 5 is located on the back side of the locking hole 13b (right side in FIG. 4). When is pushed out, the locking piece 6 faces the locking hole 13b. The locking piece 6 abuts on the ceiling of the inner circumference of the locking hole 13b and is elastically deformed to be in a reduced diameter state and advances in the locking hole 13b. By the engagement of the locking piece 6 with the locking hole 13b, the locking piece 6 is pressed downward as shown by the arrow b in FIG. 4, and is moved and deformed in the direction of the notch 7. By this reaction, the distal end portion of the insertion portion 5 is lifted upward as shown by an arrow c in FIG.

By the way, since the shaft center CL ₂ of the tip insertion portion 5 of the locking tool ₁ is set so that the phase shifts downward with respect to the shaft center CL ₁ of the shaft body 2, Bend upward with the center CL _{2 of} the shaft portion, which is biased downward, as the axis center. As a result, bending of the upper insertion unit 5 compares to that axial center of the conventional insertion portion coincides with the axial center of the shaft main body, the axial center CL ₂ of the insertion portion 5 is biasing downward Therefore, the amount of upward bending is extremely small.

Therefore, in the layout of the automatic machine, the rope 1
The scallops 13 and 14 are arranged close to each other on the left and right of 2 (when the rope is arranged horizontally, the scallops are arranged above and below the rope), and then the locking tool 1 is inserted. When performing, under this state, at least a part of the locking piece 6 of the locking tool 1 remains in the locking hole 13b of the scallop 13 on the upstream side of the rope 12, and under this state, the insertion part 5 of the locking tool 1 is inserted. Tip part 5a
However, even when it faces the locking hole 12b of the rope 12 as shown in FIG. 4, the insertion portion distal end 5a faces the center of the locking hole 12b of the rope 12 and enters. As a result, the scallop 13 on the upstream side is arranged close to the rope 12, and the locking tool 1 is passed through the locking hole 13b from the scallop 13 on the upstream side.
Even if the locking tool insertion portion 5 enters the locking hole 12b of the adjacent rope 12, there is no possibility that the tip portion 5a is caught in the locking hole 12b of the rope 12, and the tip portion 5a is It can be inserted into the locking hole 12b of the rope 12 without touching and without touching.

After that, the locking piece 6 smoothly penetrates into the locking hole 12b of the rope 12, and the locking piece 6 passes through the locking hole 13b of the scallop 13 in the same state as that of the rope 12. 1
2b, the locking hole 14b of the scallop 14 on the downstream side is inserted and passed, and the scallops 13 and 14 are locked and held by the locking tools 1 on both sides of the rope 12 as shown in FIG. It will be. A plurality of locking tools for locking and holding the scallops on the rope are locked and held at a predetermined pitch in the length direction of the rope 12, and after that, the ropes are put into the sea to wait for the growth of the scallops.
Perform scallop aquaculture.

FIG. 5 shows another embodiment of the present invention. In the present embodiment, the insertion portion 5 formed at the tip of the shaft portion 2
Was formed substantially on a spear so that the top and bottom were narrowed forward, and the tip portion 5a was formed to be sharp with a small arc. According to this,
Even if the tip portion 5a touches the locking hole 12b of the rope 12, it does not get caught on the inner circumference of the locking hole 12b because it is arcuate. As in the above, the shaft center CL ₁ of the shaft body 2 is
When, the shank center CL ₂ of the insertion portion 5, polarized in the opposite side with respect to the axial portion center CL ₁ of the shaft main body 2, shank center CL ₂ of the insertion portion 5 is lower, i.e. the locking piece 6 The phases are deviated toward each other. The eccentricity is, for example, when the diameter of the shaft body 2 is D, from the shaft center CL ₁ to the shaft center CL of the insertion portion 5.
₂ is offset downward by about 1 / 4D. In this way, the shape of the insertion portion may be set.

[0022]

As apparent from the above, according to the present invention,
Place the scallops on both sides of the rope (if the ropes are placed horizontally, the scallops will be placed on the top and bottom of the rope, or on the left and right), and make holes for the scallops and the rope to lock afterwards. When the scallops are automatically attached to the rope by the automatic machine through the locking holes by passing the tools through the locking holes, the procedure is as follows. That is, when the locking tool is inserted into the scallop locking hole on the upstream side, when the locking piece enters, the warping of the locking piece due to the reaction of the push-down action of the locking piece due to the entering of the locking hole, Due to the upward bending of the insertion portion, the axis center of the insertion portion is biased toward the side opposite to the warp direction with respect to the axis center of the shaft body so as to shift the phase as described above. As a result, the amount of bending upward of the insertion part of the tip of the locking tool into the locking hole of the rope becomes small, and the scallop on the upstream side of the locking tool insertion,
Even if the ropes are arranged close to each other and the locking holes are coaxially arranged, when the locking member passes through the upstream scallop locking hole, the insertion part may get caught in the locking hole of the rope. The rope locking hole can be inserted and passed smoothly, easily, quickly, and surely.

Therefore, the assembling work for locking and holding the scallop on the rope can be carried out smoothly, surely, and easily, and the workability can be improved, and in the past, the hook of the locking tool has been caught in the rope locking hole. Troublesome work such as stop of work, correction of the position of the locking tool, removal of the broken locking tool, and complicated maintenance work are eliminated, and workability can be greatly improved in this respect as well. In addition, the rope is caught in the rope locking hole of the locking tool,
Since the damage of the locking tool due to the like is eliminated, it is also advantageous in this respect, economically advantageous, and in addition to the above, as a whole, economically advantageous scallop assembly can be performed, and the present invention is greatly effective.
