After the contact, only the drill 19 descends against the elastic force of the compression spring 36, and when the drill 19 rises, the drill 19 separates from the scallop A and then the drill guide 20 separates from the scallop A. Relative movement such as separation is performed.

Next, the threading mechanism 5 will be described together with the thread cutting mechanism 6. As shown in FIG. 1, the threading mechanism 5 and the thread cutting mechanism 6 are disposed inside the conveyor 12 as described above. The thread cutting mechanism 6 is arranged so as to be substantially coaxial with the boring mechanism 4.

First, the threading mechanism 5 will be described in detail. The threading mechanism 5 is attached to the feed head 40 which is reciprocally moved in the vertical direction by the drive mechanism 8 and is attached to the feed head 40. The guide pipe 41 is provided as a guide means through which the yarn S is inserted. The guide pipe 41 is curved inside the feed head 40 from a substantially horizontal direction to a vertical direction. As shown in FIGS. 2 and 3, it is rotatably mounted on the base 2 via a bracket 42 and extends to the vicinity of a drum 43 around which the yarn S is wound. The yarn S pulled out from the base is guided to the outside of the base 2 and, as shown in FIG. 7, is guided to the cutting mechanism 6 by the vertical portion.

Then, the feed head 40 is moved toward the cutting mechanism 6, whereby the vertical portion of the guide pipe 41 is inserted into the cutting mechanism 6 from below, and the length corresponding to the movement amount is obtained. The yarn S is sent to the cutting mechanism 6.

The feeding operation of the yarn S is performed by the check mechanism C provided inside the feeding head 40.

Next, the non-return mechanism C will be described with reference to FIG. 19. In the horizontal portion of the guide pipe 41, which is located inside the feed head 40, a cutout is formed over about half the circumference of the peripheral wall. 41a is formed, and the surface of the thread S guided in the guide pipe 41 is exposed through the notch 41a.

It is provided so as to project forward in the bending direction (left side in FIG. 19), and its protruding end, that is, the swinging end is brought into contact with the thread S exposed from the notch 41a, whereby It is configured by a locking member 71 that holds the thread S between it and the guide pipe 41, and a spring 72 that biases the locking member 71 toward the thread S.

According to the check mechanism C, in order to insert the thread S drawn out from the guide pipe 41, the feed head 40 is moved upward as shown by an arrow (a) in FIG. When the yarn S is moved, the yarn S resists friction with the inner wall of the hole to be inserted and moves so as to be returned to the inside of the guide pipe 41. The elastic force of the spring 72 also assists the locking member 71 to swing in the direction of the arrow (d) in the drawing, and the thread S is clamped between the swing end and the guide pipe 41. The movement of the yarn S described above is restricted. Further, when the feed head 40 is moved in the arrow (B) direction in FIG. 19 and the thread S is not relatively moved in the pull-out direction, the locking member 71 is moved according to the movement of the thread S. By swinging the spring 72 in the direction against the elastic force of the spring 72 (the direction indicated by the arrow (C) in FIG. 19) to loosen the clamp of the yarn S, the withdrawal of the yarn S can be facilitated. It is supposed to do.

On the other hand, the cutting mechanism 6 is separated from the threading mechanism 5 by a head casing 44 which is reciprocally moved up and down by a predetermined stroke by the drive mechanism 8 and a head casing 44 of the head casing 44.

And means 46.

More specifically, as shown in FIGS. 7 to 9, the head casing 44 has a lid 47 at the upper end thereof, and the lid 47 is coaxial with the drill 19. Thus, the through hole 47a is formed, and the inner surface is formed with a recess 47b having a funnel-shaped inner surface continuous with the through hole 47a as shown in FIG.

The through hole 47a is formed in the radial direction with respect to the apex of the recess 47b, as shown in FIG.

The cutter 45 is formed in a columnar shape, and is mounted in the head casing 44 so that its rotation axis passes through the top of the recess 47 b.

Further, as shown in FIG. 7, the cutter 45 is formed with a convex portion 45a having a conical outer surface whose upper end is brought into sliding contact with the inner surface of the concave portion 47b of the lid 47, and A guide hole 45b, which is communicated with a through hole 47a formed in the lid 47 by the rotation thereof, is formed at a position deviated from the rotation axis in the radial direction, and is inserted between the guide hole 45b and the bottom surface of the head casing 44. By the elastic force of the disc spring K, it is constantly pressed toward the lid 47.

Then, on the contact surface between the convex portion 45a of the cutter 45 and the concave portion 47b of the lid 47, the vicinity of the peripheral edge of the through hole 47a and the guide hole 45b is inside the guide hole 45b and the through hole 47a. The cut surface of the thread S that is inserted into the thread S is cut, and the cut end of the thread S that is cut has a sharp shape inclined in the length direction (see FIG. 7).

In the present embodiment, the yarn S is supplied to the cutter 45 along the winding direction of the yarn S as indicated by the arrow (e) in FIG. In order to cut the slanted cutting surface of the thread S so as to face the inside of the winding direction of the thread S, the biasing direction of the through hole 47a and the guide hole 45b described above is inside the winding direction with respect to the rotation axis. Has been done.

On the other hand, the swinging means 46 connected to the cutter 45 extends from the head casing 44 to the inside of the base 2, and is inside a hollow elevating arm 48 connected to the drive mechanism 8. As shown in FIG. 10, the pull rod 51 is connected to the swinging end of a link 49, which is provided at the lower end of the cutter 45 so as to project in the radial direction, via a spherical joint 50. When the pull rod 51 is constantly pressed, the return spring 52 that rotates the cutter 45 so that the guide hole 45b of the cutter 45 and the through hole 47a of the head casing 44 are aligned with each other, and the drive mechanism. 8 is driven by 8 to rotate the cutter 45 in the opposite direction to the above-mentioned direction, thereby shifting the through hole 47a and the guide hole 45b to cut the yarn S. It is composed of a link mechanism (not shown).

As shown in FIGS. 8 to 10, bolts 53 are screwed on the side wall of the head casing 44, and movement is restricted by a nut 54 brought into contact with the outer wall surface of the head casing 44. Has been done.

Then, as shown in FIG. 10, the bolt 53 is projected into the inside of the head casing 44 and abuts against one end of the pull rod 51 from the front in the longitudinal direction thereof.

By moving the bolt 53 forward and backward with respect to the head casing 44, the stop position of the pull rod 51 is changed against the elastic force of the return spring 52, and the cutter 45 is moved. Is provided to adjust the initial position of the guide hole, that is, to align the guide hole 45b with the through hole 47a.

Further, the cutting mechanism 6 is reciprocally moved in the vertical direction by a predetermined stroke by the drive mechanism 8, and the stroke thereof is the upper end of the cutting mechanism 6 as shown in FIG. The highest position where the part is inserted into the through hole 11d formed in the link plate 11 of the transport mechanism 3, and the lowest position where a clearance is formed at the upper end of the cutting mechanism 6 so that a thread crushing mechanism 7 described later can enter. It is set by the distance from the position.

Further, the thread crushing mechanism 7 will be described. As shown in FIG. 5, the thread crushing mechanism 7 is provided so as to project from the base 2 toward the transport mechanism 3, and is provided above and below the transport mechanism 3.

Since the pair of thread crushing mechanisms 7 has substantially the same structure, the lower thread crushing mechanism 7 will be described in detail.

As shown in FIG. 5 and FIG. 7, the thread crushing mechanism 7 arranged below has a drive shaft 55 projecting from the base 2 toward the transport mechanism 3, and the drive shaft 55. It is provided with a pair of pressing claws 56 that are opened and closed (see FIGS. 11 and 12).

As shown in FIGS. 7, 11, and 12, the drive shaft 55 is a hollow outer shaft 57 and a solid outer shaft 57 that is fitted in the outer shaft 57 so as to be rotatable relative to each other. The inner shaft 58 and the inner shaft 58, and the pressing claws 56 are individually provided at one end of each of the outer shaft 57 and the inner shaft 58 along the tangential direction from the vicinity of the substantially outer peripheral surface of each shaft 57, 58. It is provided integrally with.

The other end of each of the shafts 57 and 58 is connected to a link mechanism (not shown) operated by the drive mechanism 8 inside the base 2 by this link mechanism. By being relatively rotated in the opposite direction around the axis, the pressing claw 56 is swung as shown by the chain line in FIG. 12, and the tips thereof are brought into pressure contact with each other. The yarn S located between the pressing claws 56 is squeezed from the radial direction to be flattened.

Further, the squeezing claws 56 are separated from each other, and a space for allowing the upward movement of the cutting mechanism 6 is formed between them, as shown in FIG.

On the other hand, as shown in FIG. 5, the upper thread crushing mechanism 7 in the upper thread crushing mechanism 7 has the tip of the squeezing claw 56 separated from each other, as shown in FIG. A space for allowing the downward movement of 30 is formed.

Therefore, the thread crushing mechanisms 7 contact the pressing claws 56 after the boring mechanism 4 is moved up and the cutting mechanism 6 is moved down. The operation timing is set so as to squeeze the thread S.

Next, the operation of the present embodiment configured as described above will be described. First, as shown in FIG. 3, in the guide groove 11c of the link plate 11 located in the transport section 3a of the transport mechanism 3, as shown in FIG. Insert the aquaculture rope P.

Next, the transport conveyor 12 of the transport mechanism 3 is intermittently moved by the connecting pitch of the link plate 11, and at the same time, the link plate 11 located at the upstream end of the transport unit 3a has both sides thereof. The scallop A is inserted from the section to locate the ears of each scallop A at the upper part and the lower part of the aquaculture rope P, respectively, and as shown in FIG. It is aligned above the through hole 11c.

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 pressed against 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 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 3 a 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 conveyer 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 descending, and the drill 19 is driven to rotate 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 cylinder 30 at the tip thereof is positioned below and the lowering thereof is blocked (see FIG. 14). When the compression spring 36 of the differential mechanism 32 provided between the drill guide stay 31 and the motor stay 24 is compressed, the drill 19 moves relative to the drill guide 20 and is further lowered. Be done.

As a result, the drill 19 penetrates the guide cylinder 30 and then sequentially processes 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.

After the completion of the punching work, the punching mechanism 4 is again raised to the maximum raised position and brought into a standby state.

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 as shown in FIG. The through hole 47a formed in the body 47 is positioned coaxially and close to the through hole formed in the scallop A and the culture rope P.

Here, the raising of the cutting mechanism 6 is stopped, but the threading mechanism 5 is subsequently raised, and as shown in FIG. 16, its guide pipe 41 guides the cutter 45. A predetermined length is inserted into the hole 45b from below.

During such a thread S insertion operation, the thread S is not returned into the guide pipe 41 due to the action of the check mechanism C incorporated in the feed head 40, and is projected from the guide pipe 41. The insertion operation described above is performed with the length maintained.

By this operation, the yarn S remaining in the cutter 45 is pushed upward, and as shown in FIG. 16, the yarn S causes the two scallops A and the culture rope P to be moved. As described above, the thread S from the guide pipe 41 is kept constant in length so that the thread S can be inserted into the scallop A and the culture rope P without fail. And the length becomes uniform.

When the thread S is made to project above the upper scallop A as described above, first, the upper thread crushing mechanism 7 is actuated, and the thread S made to project by the pressing claw 56. The tip of the thread S is gripped, and the tip of the thread S is squeezed into a flat shape as shown by a broken line in FIG.

Next, as shown in FIG. 17, the threading mechanism 5 is lowered.

With the lowering of the threading mechanism 5, since the tip of the thread S is gripped 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.

During such pulling-out operation of the thread S, the locking member 71 of the check mechanism C provided in the feed head 40 is swung so as to loosen the grip of the thread S, so that the thread S can be smoothly pulled out. The operation is performed.

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

Therefore, at the time of inserting the thread S described above, depending on the curl of the thread S and the direction of the cut surface, the penetration hole formed in the through hole 47a and the scallop A or the culture rope P is formed. The sharp tip is urged away from the inner wall surface of the hole to prevent the sharp tip from being caught, and a smoother insertion operation can be obtained.

By further lowering the cutting mechanism 6 and the threading mechanism 5 by a certain amount, as shown in FIG. 18, the lower end of the thread S penetrated by both the scallops A and the culture rope P is reached. The part is exposed from the cutting mechanism 6.

Next, by operating the lower yarn crushing mechanism 7, the lower end portion of the yarn S is squeezed and deformed into a flat shape as shown by the broken line in FIG.

As a result, both ends of the thread S are pressed and deformed into a flat shape, and the scallops A are prevented from being separated from the thread S. As a result, the scallops A are fixed to the aquaculture rope P. It

Thereafter, 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 holding 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 ear-hanging machine of the present embodiment thus configured, when the thread S 1 is inserted, the return mechanism C built in the feed head 40 ensures that the thread S returns. The thread S having a predetermined length is inserted into the scallop A and the culture rope P, whereby the scallop A is securely fixed to the culture rope P.

Further, also when pulling out the thread S from the feed head 40, the non-return mechanism C loosens the clamping of the thread S to enable smooth pulling out, and from this point also, the insertion operation of the thread S is ensured. And

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

[Effect of the device]

 As described above, the scallop ear-hanging device according to claim 1 of the present invention is configured such that the thread is passed through the ear of the scallop at a predetermined working position, and the thread is fixed to the aquaculture rope so as not to come off. In the scallop ear-hanging machine, a guide means for guiding the yarn to the insertion position is provided, and the yarn is intermittently fed by moving the guide device toward and away from the insertion position. A threading mechanism is provided, and the threading mechanism is provided with a non-return mechanism that allows movement of the thread in the feeding direction and restrains movement of the thread in the drawing direction. It has the following excellent effects.

When inserting the thread, the non-return mechanism surely prevents the thread from returning and allows the thread of a predetermined length to be inserted into the scallop or the culture rope. Can be reliably fixed.

Further, also when pulling out the yarn, it is possible to loosen the pinching of the yarn by the non-return mechanism and to smoothly pull out the yarn. From this point as well, it is possible to ensure the thread insertion operation. ..

Moreover, since the thread is directly inserted through the scallop and the aquaculture rope, the inner diameter of the holes bored therein can be made equal to or slightly larger than the outer diameter of the thread. As a result, the gap between the thread and the scallop can be reduced, and thus the scallop can be reliably prevented from coming off.

Further, in the scallop ear-hanging machine according to claim 2, the check mechanism according to claim 1 is provided so as to be swingable in the vicinity of the thread guiding means, and the swinging end portion thereof swings. It is characterized in that it is constituted by a locking member which is brought into contact with the yarn in front of the moving center in the yarn feeding direction, and an elastic member which urges the locking member toward the yarn. It has the following excellent effects.

The elastic member presses the locking member against the thread to prevent the thread from returning, and at the time of the drawing operation, the pressing force on the thread can be immediately released to make the drawing operation smooth. Therefore, it is possible to further secure the action and effect achieved by the first aspect.
