Description

  TECHNICAL FIELD The present invention relates to a culture shell lifting pin extraction device for extracting a cultured shell suspension pin that locks a cultured shell such as a scallop shell to a rope after harvesting the shellfish.

  In general, for example, in the case of aquaculture of scallops as a cultured shell, as shown in FIG. 11 (a), a resin hanging pin 1 having wedge-shaped locking portions 2 at both ends is provided, for example, with a diameter. A large number (for example, 75 to 120) of ropes R having a length of about 6 mm to 9 mm and a length of about 10 m to 15 m are inserted at a predetermined interval, and a pair of retaining pins 3 are obliquely raised at the center of the suspension pin 1. The rope R is positioned, and the suspension pin 1 is prevented from coming off and held on the rope R. For example, a dedicated insertion device is used for insertion of the suspension pin 1 (for example, described in JP-A-2002-272305).

  Then, as shown in FIG. 11 (b), a hole Sa is opened in advance in the ear part of the scallop larvae S, and the engaging part 2 of the suspension pin 1 held by the rope R is inserted into the hole Sa, so that the larvae S is suspended by being latched to the latching portion 2 of the hanging pin 1. And the rope R which suspended this juvenile S is hung on a culture shelf, it puts in the sea, culture | cultivates for a required period, and is made to grow.

  When the scallop S grows and becomes an appropriate size, the rope R is pulled up, and the shell S is pulled from the suspension pin 1 by using a dedicated device or manually, and harvested. At the time of this removal, the engaging portion 2 of the suspension pin 1 is removed from the hole Sa of the scallop S, or the suspension pin 1 is cut, or the suspension pin 1 is removed from the rope R. Then, as shown in FIG. 12, after removing the shell S, the rope R holds the suspension pin 1 that remains without being pulled out of the rope R and the suspension pin 1 that is partially cut off. It becomes a state.

JP 2002-272305 A

  By the way, the rope R after the shell S has been removed remains with the suspension pin 1 held, and cannot be reused as it is. Therefore, the rope R can be discarded or removed. Used for reuse. When the rope R is reused, the suspension pin 1 must be removed. As described above, although there is a device for insertion into the rope R, there is no removal device. Therefore, there is a problem that work is complicated and workability is poor.

  The present invention has been made in view of the above-mentioned problems, and it is possible to automatically extract a suspension pin from a rope after removing a shell, and to improve the workability of the suspension pin for cultured shellfish. An object is to provide a sampling device.

  In order to achieve such an object, the pulling device for a cultured shell suspension pin according to the present invention includes a plurality of suspension pins for a cultured shell that are inserted and held in a rope and are held and suspended on the rope. In the extraction device for the cultured shell suspension pin after removing the shell from the suspension pin for cultured shells, the tensile transport for pulling and transporting the rope into which the suspension pins are inserted along the longitudinal direction of the rope And a holding mechanism for holding the protruding portion of the hanging pin protruding from the rope being pulled and transported by the pulling and transporting mechanism, and pulling the hanging pin from the rope by the tensile force of the pulling and transporting mechanism. .

Thus, when pulling the suspension pin from the rope, if the rope is pulled and transported along the length of the rope by the tension transport mechanism, the holding mechanism protrudes from the rope during the tension transport of the rope. Hold it. Therefore, a tensile force acts strongly on the suspension pin with respect to the rope due to the tensile force of the tensile conveyance mechanism, whereby the suspension pin is pulled out from the rope.
For this reason, it becomes possible to automatically extract the suspension pin from the rope after the shell is removed, and the workability can be greatly improved as compared with the manual operation.

  And, if necessary, the holding mechanism is provided with an outer peripheral portion that has a rotation axis in a direction perpendicular to the pulling and conveying direction of the rope and a plurality of extending portions of the projecting pins protruding from the rope during the pulling and conveying, in order. A holding pulley, a rotating pulley having a rotation axis in a direction perpendicular to the direction of pulling and transporting the rope, and a protrusion of the suspension pin that is wound around the holding pulley and the rotating pulley and faces the outer periphery of the holding pulley. And an endless holding belt that holds the portion together with the outer peripheral portion of the holding pulley.

Accordingly, when the rope is pulled and conveyed along the longitudinal direction of the rope by the tension conveying mechanism, the protruding portion of the hanging pin enters between the holding pulley and the holding belt during the tensile conveyance of the rope. Thereby, the protrusion part of a suspension pin is clamped by a clamping pulley and a clamping belt, and is moved according to the locus | trajectory of the outer peripheral part of a clamping pulley. Since the rope is pulled and transported by the tension transport mechanism, a tensile force acts strongly on the suspension pin with respect to the rope, whereby the suspension pin is pulled out from the rope. Then, the suspension pin is conveyed while being held by the holding pulley, and when the holding belt is separated from the holding pulley, the holding is released and discharged.
In this case, the suspension pin is pulled out by the holding pulley and the holding belt, so that the suspension pin can be held and pulled immediately in response to the sequentially moving suspension pins. As a result, it is possible to reliably pull out, and the processing speed is greatly improved.

  Moreover, it is set as the structure which provided one pair of the said holding mechanism in the conveyance direction both sides of the said rope carried by tension | pulling as needed. As a result, when the projecting part of the hanging pin is on the left and right of the rope, even if one projecting part disappears due to cutting and only the other has a projecting part, it can be gripped by either gripping mechanism, The suspension pin is pulled out.

  Further, if necessary, a guide for guiding the rope so that a protruding portion of the suspension pin provided on the upstream side of the holding pulley of the holding mechanism and protruding from the rope can enter between the holding pulley and the holding belt. The structure is equipped with a mechanism. The rope is guided in advance by the guide mechanism so that the projecting portion of the suspension pin can enter between the retaining pulley and the retaining belt, so that the projecting portion of the suspension pin is securely retained by the retaining pulley and the retaining belt. As a result, the suspension pin is reliably pulled out.

In this case, it is effective that the guide mechanism includes a pair of guide plates that face each other with the rope interposed therebetween and form a gap through which the protruding portion of the extending portion protruding from the rope can pass. Since the guide mechanism is a simple mechanism in which the rope is sandwiched between the guide plates, the manufacturing becomes extremely easy.
In this case, it is effective that the one guide plate can be opened and closed with respect to the other guide plate. Since the guide plate is opened and closed, the rope can be easily attached, and the rope can be surely positioned in the guide plate.

  In addition, if necessary, the tension conveying mechanism is connected to a main roller on which the rope is wound and rotated, and the rope wound on the main roller is pressed against the main roller to cooperate with the main roller. And a pressing roller for pulling and conveying the rope. Thereby, the rope is pulled and conveyed while being pressed by the pressing roller by the rotational force of the main roller. Since it is pressed by the pressing roller, it is reliably pulled and conveyed.

Moreover, it is set as the structure provided with the rope support body which supports the said rope in the upstream from the holding position of the said suspension pin by the said holding mechanism as needed, and provides tension | tensile_strength to this rope. The rope can be securely tensioned and transported in the stretched state, so that it can be prevented from being bent or twisted in the middle of transportation, and the tension transportation can be reliably performed to pull out the suspension pin. be able to.
In this case, it is effective that the rope support is composed of a tension roller around which the rope is wound. In addition to the tension roller, it is effective to provide a support rod that is provided upstream of the tension roller and supports the rope as the rope support.

  According to the pulling device for a cultured shell suspension pin of the present invention, when the suspension pin is pulled out from the rope, the rope is pulled and transported by the tension transport mechanism, and the projecting portion of the suspension pin protruding from the rope is gripped only by the gripping mechanism. Therefore, it is possible to pull out the suspension pin from the rope by applying a strong tensile force to the suspension pin against the rope, so that the suspension pin can be automatically removed from the rope after removing the shell. Workability can be greatly improved compared to work.

  In addition, if the holding mechanism is constituted by a holding pulley and a holding belt, and the pulling of the suspension pin is performed by holding with the holding pulley and the holding belt, the suspension pin that moves sequentially is immediately supported. It can be held and pulled, so that it has good responsiveness, can be pulled out reliably, and the processing speed can be greatly improved.

As shown in FIG. 5, a gap through which the rope R can pass when the rope R is mounted is provided between the one pulley pulley 26 and the other pulley pulley 36.

  Next, the power transmission system of the holding mechanisms 20 and 30 will be described. As shown in FIGS. 3 and 10, a chain transmission mechanism 50 is provided on the motor shaft 18 of the electric motor 17. Specifically, as shown in FIG. 10, the chain transmission mechanism 50 includes a chain 51 formed of an endless timing belt, a main sprocket 52 that is provided on the shaft of the electric motor 17 and is engaged with the endless chain 51. The machine base 5 is provided with an adjustable axial position, and a chain 51 is wound around and meshed to adjust the tension of the chain 51. The tension adjusting sprocket 53 meshes with the outer periphery of the chain 51 and the one holding mechanism 20 described above. A supporting sprocket 54 is provided which is provided on a rotating shaft 24 to which the holding pulley 21 is fixed and rotates the holding pulley 21 through the rotating shaft 24.

As shown in FIG. 10, when the electric motor 17 rotates, the motor shaft 18 rotates, the main roller 11 rotates through the rotating shaft 16, and the rope R is pulled and conveyed.
Further, when the motor shaft 18 rotates, the rotating shaft 24 of the sub sprocket 54 is rotated via the main sprocket 52 and the chain 51 of the chain mechanism 50, thereby rotating the one holding pulley 21.
Further, when one holding pulley 21 is rotated, the rotational force is transmitted to the other holding belt 33 via the one holding belt 23, the one rotating pulley 22, and the other rotating pulley 32. The other holding pulley 31 is rotated by the holding belt 33.

As shown in FIGS. 1 and 6 to 9, the guide mechanism 60 is provided upstream of the holding pulleys 21 and 31 of the holding mechanisms 20 and 30, and the protruding portion 4 of the hanging pin 1 protruding from the rope R holds the guide mechanism 60. The rope R is guided so that it can enter between the pulleys 21 and 31 and the holding belts 23 and 33. Specifically, the guide mechanism 60 faces up and down across the rope R, and forms a gap e (FIG. 9) through which the protruding portion 4 of the suspension pin 1 protruding from the rope R can pass. It is configured with. One guide plate 61 is attached to the other guide plate 62 so as to be openable and closable. That is, the lower guide plate 62 is fixed to the machine base 5, and the upper guide plate 61 is rotatably attached to the lower guide plate 62 through a hinge by operating the lever 63. Each guide plate 61, 62 is formed such that its tip is positioned immediately before the holding pulleys 21, 31 of the holding mechanisms 20, 30. Further, a concave portion 64 (FIG. 8B) into which the rope R is slidably fitted is formed at the center of each guide plate 61,62. Accordingly, the rope R is sandwiched between the concave portions 64 and slides on the concave portion 64, and the protruding portion 4 of the hanging pin 1 protruding from the rope R is formed between the guide plates 61 and 62 on the left and right sides of the concave portion 64. The posture is regulated and guided by the gap e. In this case, since the guide mechanism 60 is a simple mechanism in which the rope R is sandwiched between the guide plates 61 and 62, the manufacturing becomes extremely easy.
A support rod 65 (FIG. 2) on which the rope R is supported protrudes from the rear ends of the upper guide plates 61 and 62. By supporting the rope R on the support rod 65, the upper guide plates 61 and 62 are closed by the own weight of the rope R.

  A rope support that supports the rope R and applies tension to the rope R upstream of the holding position of the suspension pin 1 by the holding mechanisms 20 and 30 and upstream of a position where the guide mechanism 60 is located. 70 is provided. As shown in FIGS. 5 and 6, the rope support 70 is composed of a tension roller 71 around which the rope R is wound and the rope R is in sliding contact. The tension roller 71 is provided integrally with the rotary pulleys 22 and 32 between the pair of rotary pulleys 22 and 32 described above. That is, since the tension roller 71 is also rotated by the rotation of the rotary pulleys 22 and 32, a sliding resistance acts more strongly on the rope R, and a tensile force in the direction opposite to the conveying direction is generated. Is done.

  In addition to the tension roller 71, a support rod 72 that supports the rope R and is provided on the machine base 5 on the upstream side of the tension roller 71 as the rope support 70. The support rod 72 is provided with a guide rod 73 extending integrally from the base end portion and parallel to the support rod 72. The rope R is inserted between the support rod 72 and the guide rod 73. When the rope R passes between the support rod 72 and the guide rod 73, the kinking of the rope R is corrected, and the posture of the rope R is stabilized. Further, since the sliding resistance of the rope R with respect to the support rod 72 causes a tensile force in the direction opposite to the conveying direction, this also applies tension to the rope R.

Therefore, when the suspension pin 1 is extracted from the rope R by the cultured shell suspension pin extraction device K according to this embodiment, it is performed as follows.
First, the upper guide plate 61 is opened through the lever 63. In this state, the electric motor 17 is started, the rope R is passed between the support rod 72 and the guide rod 73, between the one holding pulley 21 and the other holding pulley 31, and between the one pulley 26 and the other idler pulley. The rope R is passed between the vehicle pulley 36 and the rope R is placed on the tension roller 71, and the pressing roller 12 is manually separated from the main roller 11 against the urging force of the coil spring 15, and the main roller 11 Place the rope R on the top.

Then, when the pressing roller 12 is free, the pressing roller 12 is pressed against the main roller 11 by the urging force of the coil spring 15 and grips the rope R. Thus, the rope R is pulled and conveyed while being pressed by the pressing roller 12 by the rotational force of the main roller 11. In this case, since the rubber ring 13 is attached to the main roller 11, the frictional resistance is increased, so that the tensile conveyance is reliably performed.
Further, when the rope R is pulled, the rope R comes into contact with and pushes the support rod 65 provided on the upper guide plate 61, so that the upper side can be operated without operating the lever 63. The guide plate 61 is pulled and closed. Accordingly, the rope R slides between the concave portions 64 of the guide plates 61 and 62. In this case, since the guide plate 61 is opened and closed, the rope R can be reliably positioned in the guide plates 61 and 62.

Thereby, the rope R is pulled and conveyed along the longitudinal direction of the rope R. In this conveying process, the protrusion 4 of the suspension pin 1 inserted into the rope R is guided by the gap e between the guide plates 61 and 62 of the guide mechanism 60 to correct its posture, and the tips of the guide plates 61 and 62 are corrected. Go downstream from the section.
And when the protrusion part 4 of the suspension pin 1 protrudes to the other holding mechanism 30 side, as shown in FIG. 8, there are the holding pulley 31 and the holding belt 33 of the other holding mechanism 30. It enters between the holding pulley 31 and the holding belt 33. Thereby, the protrusion part 4 of the suspension pin 1 is clamped by the clamping pulley 31 and the clamping belt 33, and is moved upward according to the locus of the outer peripheral part of the clamping pulley 31. Since the rope R is pulled and conveyed toward the main roller 11 by the tension conveying mechanism 10, a tensile force acts strongly on the hanging pin 1 against the rope R, whereby the hanging pin 1 is pulled out from the rope R. It is. The suspension pin 1 is conveyed while being held on the upper side of the holding pulley 31, and the holding belt 33 is released from the holding pulley 31 on the upper side away from the holding pulley 31. Discharged.

In this case, the rope R is guided in advance by the guide plates 61 and 62 of the guide mechanism 60 so that the protruding portion 4 of the suspension pin 1 can enter between the holding pulley 31 and the holding belt 33. Thus, the protruding portion 4 of the suspension pin 1 is clamped by the clamping pulley 31 and the clamping belt 33, and the suspension pin 1 is reliably pulled out.
Further, in this case, there is a tension roller 71 and a support rod 72 as a rope support 70 that supports the rope R on the upstream side of the holding position of the suspension pin 1 by the holding mechanism 30 and applies tension to the rope R. The rope R can be reliably tensioned and transported in an extended state, so that it is prevented from being bent or kinked during transport, and the tension transport is reliably performed, and the suspension pin 1 is pulled out. Can be performed reliably.

  Further, in the case where the protruding portion 4 of the extending portion 1 protrudes to one holding mechanism 20 side and the other holding mechanism 30 side is cut and has no protruding portion 4, as shown in FIG. When the protruding portion 4 of the suspension pin 1 protruding toward the holding mechanism 20 exits the guide plates 61 and 62, the holding pulley 21 and the holding belt 23 of one holding mechanism 20 are present there. And the holding belt 23. Thereby, the protrusion part 4 of the suspension pin 1 is clamped by the clamping pulley 21 and the clamping belt 23, and is moved upward according to the locus of the outer peripheral part of the clamping pulley 21. Since the rope R is pulled and conveyed toward the main roller 11 by the tension conveying mechanism 10, a tensile force acts strongly on the hanging pin 1 against the rope R, whereby the hanging pin 1 is pulled out from the rope R. It is. Then, it is conveyed while being held on the upper side of the holding pulley 21, and the holding belt 23 is released on the upper side away from the holding pulley 21, so that it is dropped below the machine base 5 and discharged.

In this case, the rope R is guided in advance by the guide plates 61 and 62 of the guide mechanism 60 so that the protruding portion 4 of the suspension pin 1 can enter between the holding pulley 21 and the holding belt 23. Thus, the protruding portion 4 of the hanging pin 1 is held by the holding pulley 21 and the holding belt 23, and the extending portion 1 is reliably pulled out. As described above, since the holding mechanisms 20 and 30 are provided on the left and right sides, even when the hanging pin 1 protrudes on the left and right sides of the rope R, one side is cut and the other side is not provided. Since the protrusion 4 can be pulled out, the suspension pin 1 can be pulled out reliably.
Further, in this case, there are a tension roller 71 and a support rod 72 as a rope support 70 that supports the rope R and applies tension to the rope R on the upstream side of the holding position of the suspension pin 1 by the holding mechanisms 20 and 30. Therefore, it is possible to reliably apply tension to the rope R and to convey the rope R in an extended state. Therefore, it is possible to prevent a situation where the rope R is bent or kinked during the conveyance, and the tension pin 1 is reliably conveyed. Can be reliably pulled out.

Further, the pulling-out of the suspension pin 1 is held by the holding pulleys 21 and 31 and the holding belts 23 and 33, so that the suspension pin 1 can be held and pulled immediately in response to the sequentially moving suspension pins 1. Therefore, the responsiveness is good and the extraction can be surely performed, and the processing speed is greatly improved.
In this manner, the hanging pins 1 are sequentially pulled out in the process of pulling and transporting the rope R. When the drawing of one rope R is completed, the guide plate 61 of the guide mechanism 60 is opened again by operating the lever 63, and the processing for the next other rope R is performed in the same manner as described above.
