Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scallop ear-hanging machine, and more particularly to a scallop ear-hanging machine which is preferably used when retaining a scallop juvenile on a culture rope. .

[0002]

2. Description of the Related Art Conventionally, various kinds of scallop shell ear suspension machines have been proposed. For example, in a scallop ear-hanging machine disclosed in Japanese Patent Laid-Open No. 63-123326 and the like, a through hole is coaxially formed by using a drill in the aquaculture rope and the scallop, and the through hole is inserted into the through hole. The end of the thread is bound with a thread to prevent the scallop from sticking to the aquaculture rope, so that the scallop is suspended from the aquaculture rope.

[0003]

By the way, the scallop has a tendency to close its mouth by the impact when adjacent scallops are shaken by the flow of the tide in the sea and the adjacent scallops collide with each other. Therefore, if the scallops were easily shaken by the current of the tide and suspended from the ear so that they would hit each other, the time for which the mouth was closed would increase and the amount of nutrients and oxygen contained in seawater could be taken into the body. There is less and the growth of scallops slows down. In addition, scallops have the habit of swimming around in the sea by blowing out the sucked water. Therefore, in order to grow the scallops to a sufficiently large size in the cultivation of scallops, the scallops should be fixed to the aquaculture rope so that they cannot move easily so that they do not move around and consume unnecessary energy. Is desirable.

[0004] However, in the conventional scallop shell ear suspension machine, the scallop shell is suspended by a long thread penetrating the aquaculture rope, and is also used for ear suspension. The yarn has the flexibility to be easily bent. As a result, the scallops that are suspended by the conventional scallop ear suspension are suspended by the long and flexible thread on the aquaculture rope. There is a problem that they are easily rocked and hit each other or move around themselves, which slows down their growth. Therefore,
Although it is possible to shorten the length of the thread used for hanging the ear, in the conventional ear-hanging machine for scallops, there are problems with the mechanism of positioning the scallops with respect to the aquaculture rope and the thread for hanging the ears. Due to a mechanical problem that binds both ends together, the length of the thread used to suspend the ears cannot be shortened.

It is projected into the inside of the head casing 44 and abuts against one end of the pull rod 51 from above in the length direction thereof. By moving the bolt 53 back and forth with respect to the head casing 44, the pull rod 51 is resisted against the elastic force of the return spring 52.
It is provided for adjusting the initial position of the cutter 45, that is, for aligning the guide hole 45b with the through hole 47a by changing the stop position.

Further, the cutting mechanism 6 is reciprocally moved in the vertical direction by a predetermined stroke by the drive mechanism 8, and this stroke is, as shown in FIG. 7, the upper end portion of the cutting mechanism 6. Is the highest position to be inserted into the through hole 11d formed in the link plate 11 of the transport mechanism 3 and the lowest position to form a gap into the upper end of the cutting mechanism 6 into which the thread crushing mechanism 7 described later can enter. It is set at intervals.

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
It is provided above and below the transport mechanism 3. Since the pair of thread crushing mechanisms 7 have substantially the same structure, the lower thread crushing mechanism 7 will be described in detail. As shown in FIGS. 5 and 7, the thread crushing mechanism 7 disposed below is provided with a drive shaft 55 projecting from the base 2 toward the transport mechanism 3 and opened and closed by the drive shaft 55. It is provided with a pair of pressing claws 56 (see FIGS. 11 and 12).

Next, the operation of the scallop ear suspension of this embodiment having the above-described structure will be described.

First, as shown in FIG. 3, the aquaculture rope P is inserted into the guide groove 11c of the link plate 11 located in the carrying section 3a of the carrying mechanism 3. Next, the transport conveyor 12 of the transport mechanism 3 is intermittently moved by the connection pitch of the link plate 11, and the transport unit 3
The pair of scallops A is inserted into the link plate 11 located at the upstream end of a from both sides of the link plate 11 as shown in FIG.
As shown in FIG. 5, one of the pair of ears of each scallop A is positioned so that one of the ears is in close contact with above or below the aquaculture rope P, and as shown in FIG. The plate 11 is positioned 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 is supported by the lower guide plate 17, and the pressing lever 13 constituting the upper part is guided by the upper guide plate 18. Since the upward rotation is restricted, the scallop A is inserted into the accommodating recess 11b of the link plate 11 by elastically deforming the brush 14 attached to the presser lever 13 by the above-described insertion operation. It 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 positioned and held at the above-described position. Such scallop A insertion work 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 continuously transferred to the transport mechanism 3. Installing. In this embodiment, since the left and right accommodation recesses 11b of the link plate 11 are provided with a height difference, one of the pair of scallops A has an ear of one of the scallops located above the aquaculture rope P. Thus, the work of positioning so that the ear of the other scallop is located below the aquaculture rope can be easily performed.

By the way, in general, scallops have front and back sides, one of which has a blackish appearance, while the other has a whitish appearance. Then, when positioning the scallop on the link plate 11 as described above,
Utilizing this property, the scallop A placed on the upper placing surface of the link plate 11 is placed on the lower placing surface of the link plate 11 on the contrary, so that its blackish color is on the front side. Place the placed scallop A so that its whitish color is on the front side. Then, of the pair of ears of the scallop A, the ears farther from the heart of the scallop are overlapped with the aquaculture rope P. Therefore, since the through hole formed by the perforation mechanism 4 is formed in the ear of the scallop that is far from the heart, the adverse effect of forming the through hole affects the heart of the scallop. This can be prevented, and thus the survival rate of the scallop after the ear hanging work can be significantly increased.

The scallop A and the aquaculture rope P, which are positioned and mounted on the link plate 11 as described above, are
Along with the intermittent movement of the transport conveyor 12, the punching mechanism 4, the threading mechanism 5, or the thread cutting mechanism 6 is sequentially opposed to and stopped at that position. And
While the movement of the transport conveyor 12 is stopped,
The punching mechanism 4, the threading mechanism 5, the cutting mechanism 6, and the thread crushing mechanism 7 are operated.

Each of these individual operations will be detailed below. The piercing mechanism 4 includes a scallop A and a culture rope P.
While the transport conveyor 12 in which is positioned is transported, as shown in FIG. 13, it is positioned at the highest position by the action of the cam 28, and the upper and lower thread crushing mechanisms 7 move the squeezing claws 56 thereof. It is held open. 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 driven to rotate by the electric motor 21.

The drill guide 20 comes into contact with the upper surface of the upper scallop A on which the guide cylinder 30 at the tip thereof is positioned below to prevent the drill guide 20 from descending (see FIG. 14). In the drill 19, 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 guide 20 is moved relative to the drill guide 20 and is further lowered. 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. 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 highest position and is in the standby state.

When the punching work 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. Through hole 4 formed in 47
7a is located at a position coaxial with and close to the through holes formed in the scallop A and the culture rope P.

Here, although the cutting mechanism 6 is stopped from moving upward, the threading mechanism 5 is subsequently moved upward, so that the guide pipe 41 is guided into the guide hole of the cutter 45 as shown in FIG. A predetermined length is inserted into 45b from below. By this operation, the thread S remaining in the cutter 45 is pushed upward, and as shown in FIG. 16, the thread S penetrates both scallops A and the aquaculture rope P and is above it. Is projected to.
In this way, the thread S is pushed upward because frictional resistance is given to the thread S at the curved portion of the guide pipe 41, and the frictional resistance prevents the thread S from slipping into the guide pipe 41. Because it is done.

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

Then, 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 thread S is pulled out from the guide pipe 41 by the descending amount of the threading mechanism 5. 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 moved by the swinging means 46.
17 is rotated as shown by the arrow in FIG. 17, so that 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 cutting mechanism 6 and the threading mechanism 5 by a certain amount, as shown in FIG. 18, the lower ends of the threads S penetrated by both the scallops A and the culture rope P are moved. , Exposed from the cutting mechanism 6. Next, the lower thread crushing mechanism 7 is actuated to squeeze and deform the lower end portion of the thread S into a flat shape as shown by the broken line in FIG. By this, the thread S
Both ends of the scallop 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. Thereafter, the upper and lower yarn crushing mechanisms 7 release the yarn S and the transport mechanism 3 is operated by one pitch, so that the link plate 11 at the subsequent stage is fed between the punching mechanism 4 and the cutting mechanism 6. The scallop A is sequentially fixed to the aquaculture rope P by the same action.

On the other hand, the link plate 1 on which the scallop A, which has been fixed to the aquaculture rope P as described above, is placed.
1 and a pressing lever 13 for pressing the scallop A
Is disengaged from the both guide plates 17 and 18, and the link plate 11 is wound around the pulley 9 at the front in the conveying direction as shown in FIG. 4, and the pressing lever 13 is Since the upward rotation is free, the elastic force of the brush 14 that has been elastically deformed in the initial stage of the winding on the pulley 9 causes the brush 14 to slightly rotate upward, and the link plate 11 is rotated. As is further wound around the pulley 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 conveyor 12.

When the aquaculture rope P on which the scallops A are suspended as described above is extended in the vertical direction, the scallops A are shown in FIG.
As shown in FIG. 3, the thread S penetrating the aquaculture rope P is suspended in a state of being respectively locked at both ends. At this time, in the present embodiment, the bending rigidity of the thread S is increased so that the thread S can be easily inserted into the through holes formed in the scallop and the culture rope P. The thread S passed through the
As shown in FIG. 3, the rod extends substantially horizontally and in a rod shape. As a result, the scallops that are respectively suspended at both ends of the thread S cannot move around the aquaculture rope P even if they are shaken by the tide in seawater, and thus do not collide with each other. . Further, since the aquaculture rope P functions as a cushion, the impact of the scallops hitting the aquaculture rope P is extremely small. Therefore, the scallops A hung on the aquaculture rope P by the scallop ear suspension of this embodiment do not close their mouths due to the impact of hitting each other, so that they sufficiently absorb oxygen and nutrients in seawater. It will be possible to grow faster. If the length of the thread S that suspends the scallop A from the aquaculture rope P is further shortened, for example, as shown in FIG. 15, a pair of scallops A are aquacultured with the aquaculture rope P being sandwiched between their ears. It can be hung on the rope P. As a result, a pair of scallop A
As shown in FIG. 4, since the body portion of the scallop can be brought into close contact with the aquaculture rope P, the movement of the scallop A can be further reduced, thereby suppressing wasteful energy consumption of the scallop. Its growth can be accelerated even further.

According to the scallop shell lifting machine of the present embodiment thus configured, the transport mechanism 3 is provided with a plurality of link plates 11 and a presser lever rotatably mounted on these link plates 11. 13 and the link plates 11 are connected endlessly and wound between a pair of pulleys 9 and 10. The scallop A is horizontally placed between the link plate 11 and the presser lever 13. Since the scallop A is held and conveyed, its positioning is easy when the scallop A is mounted on the conveyance mechanism 3, and
The positional deviation is suppressed even during transportation. Therefore, workability is greatly improved. Further, the position accuracy of the piercing at the time of the piercing work in the subsequent stage is improved, and it becomes possible to pierce the two overlapping scallops A and the culture rope P with a continuous through hole reliably. Is securely fixed to the aquaculture rope P.

Further, it becomes possible to dispose the punching mechanism 4, the threading mechanism 5, the cutting mechanism 6, the thread crushing mechanism 7 and the like in the vertical direction with respect to the transport mechanism 3.
Horizontal expansion of the device is suppressed, and as a result, space can be saved when installing the device. on the other hand,
In the case where the installation space can be sufficiently secured, the mounting area of the scallop A on the transport conveyor 12 can be set to be long by lengthening the transport unit 3a of the transport mechanism 3, and thus the transport mechanism 3 The transport speed is increased and the work efficiency is improved.

Further, even when the scallop A, which has been fixed to the aquaculture rope P, is separated from the transport mechanism 3, after the link plate 11 is wound around the pulley 9, a holding lever for holding the scallop A is held. Since 13 is rotated by its own weight to release the holding of the scallop A, the smooth separation is performed.

Moreover, in the present embodiment, the cutting mechanism 6
Therefore, when the thread S is cut, the cut end thereof is slanted to have a sharp shape, so that when the thread S is inserted into the scallop A or the culture rope P, smooth and reliable insertion becomes possible,
From this point as well, the reliability of the work is secured.

The shapes, sizes, etc. of the constituent members shown in the above embodiment are merely examples, and can be variously changed based on design requirements and the like. For example, in the above-described embodiment, an example in which the transport mechanism 3 is intermittently moved and the scallop A and the aquaculture rope P are pierced and threaded and fixed when the transport mechanism 3 is stopped has been described. Alternatively, the following configuration can be adopted. That is, the transport mechanism 3 is moved at a constant speed, and the above various operations are performed while the various devices such as the punching mechanism 4 and the threading mechanism 5 are moved following the movement direction of the transport mechanism 3. . Even in the case of such a configuration, since the above-mentioned various devices can be arranged along the vertical direction, the movement space of these various devices is almost equal to the transport mechanism 3.
It is limited only to the upper part of the, and the expansion of the installation area in the horizontal direction is suppressed as much as possible.

FIGS. 19 and 20 show a second embodiment of the present invention. In this embodiment, there are a large number of 20 pieces of 6 nylon nylon Tegus thread having a diameter of 0.34 mm. Brushes 14 that are planted on the inside of the vertical plane (link plate 1
The guide groove 11c of No. 1) is inclined. With this configuration, when the scallop A on the link plate 11 is clamped by the pressing lever 13, the inclination of the brush 14 causes the scallop A to move the scallop A to the link plate 11.
The scallop A acts on the link plate 1 because it acts toward the guide groove 11c of the link plate (toward the central portion in FIG. 19).
It is further prevented from separating to the side of 1.

21 and 22 show a third embodiment of the present invention, in which the pressing lever 13 of the above embodiment is used.
Is connected to the link plate 11 at the front end in the conveying direction by a connecting pin 16 so as to be rotatable in the vertical direction. In the plane orthogonal to the transport direction of the link plate 11, the link plate 11 is rotatably attached within a range of a predetermined angle in the vertical direction (a range of a horizontal position and a position inclined upward by 60 degrees). In addition, as shown in FIG. 22, in the present embodiment, the pair of left and right scallops A is a line with respect to the center line m (culture rope P) of the link plate 11 in plan view (as viewed from above). It is placed in a symmetrical position. That is, the pair of scallops A are positioned so that their respective body parts are laterally distributed with respect to the aquaculture rope P when viewed from the axial direction of the through hole through which the thread S bored in the aquaculture rope P is inserted. It With this configuration, similarly to the above embodiment, the scallop A is securely sandwiched between the link plate 11 and the pressing lever 60 via the brush 14, and the scallop A is smoothly moved in a predetermined posture and position. Can be held at.

When positioning the pair of scallops A, as shown in FIG. 22, the scallop A should be positioned so that the boundary between the ears and the body of the scallop A extends substantially parallel to the aquaculture rope P. For example, the bulge of the body of the scallop A can be prevented from coming into contact with the culture rope P. As a result, the ears of the scallop A can be surely brought into close contact with the aquaculture rope P, and thus the length of the thread S that suspends the scallop A from the aquaculture rope P can be shortened.
