More specifically, the cam 28 lowers the punching mechanism 4 from the highest position L1 to the lowest position L2 between the time T0 and the time T1, and holds it at the lowest position L2 until the time T2. However, the profile is such that it returns from the lowest position L2 to the highest position L1 until time T3, and during the latter half of the time T0 to T1 the scallop A and the culture rope R by the piercing mechanism 4 are reached. Corresponds to the step of perforating.

Further, the cam 64 moves the threading mechanism 5 from the lowest position L3 to the highest position between the time T4, that is, the time before the end time T1 of the punching process and the time T5 immediately before the time T3. The profile is such that the position is moved to the position L4, and further after time T6 when a predetermined time has elapsed from time T5, the position is moved again toward the lowest descent position L3.

Then, between the time T1 and the time T2, the contact plate 81 of the threading mechanism 5 contacts the cam follower 26 of the punching mechanism 4 at the time when the curve A and the curve B intersect. The threading mechanism 5 and the boring mechanism 4 are moved after the time when the curve A and the curve B intersect between the time T2 and the time T3.

At this time, in the transfer conveyor 12 of the transfer mechanism 3, the link plate 11 constituting the lower part thereof is supported by the lower guide plate 17, and the pressing lever 13 constituting the upper part has the upper guide. Since the upward rotation is restrained by being guided by the plate 18, the scallop A is elastically deformed by the insertion operation described above while the brush 14 attached to the presser lever 13 is elastically deformed. It is inserted into the accommodation recess 11b.

As a result, the scallop A is brought into pressure contact with the accommodating recess 11b of the link plate 11 by the elastic force of the brush 14 and is positioned and held at the position as described above.

The insertion work of the scallop A as described above is sequentially performed on the link plate 11 that is sequentially sent to the upstream side of the transport unit 3a by the intermittent movement of the transport conveyor 12 described above, and the scallop A is transported by the transport mechanism 3. Install continuously to.

The scallop A and the aquaculture rope P, which are thus positioned and placed on the link plate 11, are sequentially moved along with the intermittent movement of the transport conveyor 12, the boring mechanism 4, the threading mechanism 5, or It is opposed to the thread cutting mechanism 6 and stopped at that position.

Then, while the movement of the transport conveyor 12 is stopped, the punching mechanism 4, the threading mechanism 5, the cutting mechanism 6, and the yarn crushing mechanism 7 are operated.

Each of these individual operations will be detailed below. The piercing mechanism 4 is located at the highest position by the action of the cam 28 while the conveyor 12 on which the scallop A and the culture rope P are positioned is conveyed, as shown in FIG. The upper and lower thread crushing mechanisms 7 are held with their pressing claws 56 opened.

As a result, the cam 28 is operated, the drill guide 20 and the drill 19 of the drilling mechanism 4 start to descend, and the drill 19 is rotationally driven by the electric motor 21.

Then, the drill guide 20 comes into contact with the upper surface of the scallop A on the upper side where the guide tube 30 at the tip thereof is positioned below and the lowering thereof is prevented (see FIG. 16). The drill 19 is moved relative to the drill guide 20 by compressing the compression spring 36 of the first differential mechanism 32 provided between the drill guide stay 31 and the motor stay 24. It is further lowered.

As a result, the drill 19 is passed through the guide cylinder 30 and then sequentially processed into the upper scallop A, the aquaculture rope P, and the lower scallop A located below the guide cylinder 30. Then, as shown in FIG. 5, continuous through holes are formed in them.

When the boring operation is completed in this way, the cutting mechanism 6 and the threading mechanism 5 located below the link plate 11 are raised by the cam 63, and as shown in FIG. The through hole 47a formed in the lid 47 of the mechanism 6 is positioned coaxially and close to the through holes formed in the scallop A and the aquaculture rope P, and the third differential mechanism is provided. An abutting plate 81 constituting 80 is brought into contact with the cam follower 26 of the boring mechanism 4.

Here, the raising of the cutting mechanism 6 is stopped by being brought into contact with the stopper 76 that constitutes the second differential mechanism 70. Following this, the threading mechanism 5 is stopped. As shown in FIG. 18, the guide pipe 41 is raised and inserted into the guide hole 45b of the cutter 45 from below under a predetermined length.

By this operation, the yarn S remaining in the cutter 45 is pushed upward, so that the yarn S causes the two scallops A and the cultivating rope P to be moved as shown in FIG. It penetrates and is projected above it.

Then, in such a thread S inserting operation, the third differential mechanism 80 causes the threading mechanism 5 and the punching mechanism 4 to move integrally, so that the tip of the thread S is lowered to the lowest position. The drill 19 and the thread S are raised at the same time while being brought close to the tip of the drill 19 in the position and maintaining the brought relative distance.

By such an operation, as the drill 19 is pulled out, the thread S is inserted so as to be replaced with the drill 19, and until the thread S is completely inserted, both scallops A and The displacement of the aquaculture rope P is prevented by the drill 19, so that the aquaculture rope P is securely inserted.

When the thread S is projected above the upper scallop A as described above, first the cam 28 moves the punching mechanism 4 to the highest position, and then the upper thread crushing mechanism 7 is moved. Is operated, the tip of the projected thread S is gripped by the pressing claw 56, and the tip of the thread S is further operated by the operation of the upper thread crushing mechanism 7 as shown by a broken line in FIG. It is pressed flat.

Next, as shown in FIG. 19, the threading mechanism 5 is lowered.

With the lowering of the threading mechanism 5, since the tip of the thread S is grasped by the upper thread crushing mechanism 7, the lowering amount of the threading mechanism 5 from the guide pipe 41 is equal to that of the guide pipe 41. Be withdrawn.

After that, the cutting mechanism 6 and the threading mechanism 5 are lowered by a slight amount in synchronization with each other, and then the cutter 45 is rotated by the swinging means 46 as shown by an arrow in FIG. As a result, the thread S is sharply cut at the inclined contact surface between the cutter 45 and the lid 47 of the head casing 44.

By further lowering the threading mechanism 5 by a certain amount, the action of the second differential mechanism 70 causes the threading mechanism 5 and the cutting mechanism 6 to descend to the lowest position. As shown in FIG. 20, the lower end portion of the thread S penetrated by both the scallops A and the culture rope P is exposed from the cutting mechanism 6.

Then, the lower yarn crushing mechanism 7 is operated to squeeze and deform the lower end portion of the yarn S into a flat shape as shown by the broken line in FIG.

As a result, both ends of the thread S are squeezed and deformed into a flat shape to prevent the scallops A from separating from the thread S, and as a result, the scallops A are fixed to the aquaculture rope P. It

After this, the upper and lower thread crushing mechanisms 7 release the thread S, and the transport mechanism 3 is operated by one pitch, so that the link plate 11 at the subsequent stage is punched by the punching mechanism 4 and the cutting mechanism. Then, the scallop A is sequentially fixed to the aquaculture rope P by the same action.

On the other hand, as described above, the link plate 11 on which the scallops A that have been fixed to the aquaculture rope P are placed, and the pressing lever 13 that presses the scallops A are the guide plates 17 described above. .18, the link plate 11 is wound around the pulley 9 on the front side in the transport direction as shown in FIG. 4, and the presser lever 13 is rotated upward. Since it is in the free state, the elastic force of the brush 14 which has been elastically deformed at the initial stage of winding the pulley 9 causes the link plate 11 to be slightly rotated upward, so that the link plate 11 is further rotated. As it is wound around 9, the pressing lever 13 rotates in the direction away from the link plate 11 by its own weight.

As a result, the grip of the scallop A by the link plate 11 and the pressing lever 13 is naturally released, and the scallop A and the aquaculture rope P are smoothly separated from the transport conveyor 12.

According to the scallop shell ear suspension device of the present embodiment thus configured, the main part of the thread crushing mechanism 7 for squeezing the thread S 1 is arranged in the base 2 and the base 2 Since only the tip of the drive shaft 55 that constitutes the thread crushing mechanism 7 is exposed to the outside of the base, only a portion exposed to seawater is required. As a result, the base 2 is exposed to the outside. It is only costly to take anticorrosion measures in the small area.

Further, the drive shaft 55 is constituted by a hollow outer shaft 57 and an inner shaft 58 which is relatively rotatably fitted in the outer shaft 57, and the pressing claw 56 is formed by these shafts 57, 58. Since it is attached to the tip of the pressing claw 56, the movement of the pressing claw 56 is in the circumferential direction of the shafts 57 and 58, thereby reducing the operating range of the pressing claw 56 and when the pressing claw 56 is in the non-pressing position. In addition, a space is formed between the squeezing claws 56, so that the operation areas of other devices can be easily secured.

Therefore, it is possible to avoid interference between the thread crushing mechanism 7 and other various devices as much as possible, and the degree of freedom in the layout of the device is significantly improved.

It should be noted that the shapes, dimensions, etc. of the respective constituent members shown in the above embodiment are merely examples, and can be variously changed based on design requirements and the like.
