Description

The present invention relates to a shell hanging pin removing device for removing a shell hanging pin inserted in a rope from the rope.

In ear-hanging aquaculture of scallops, as shown in FIG. 1 (b), a large number of scallops are hung on a culture rope having a length of 10 to 15 m along the length direction. In order to hang scallops on a farming rope, for example, a shell hanging pin (generally called an age pin) having a shape as shown in FIG. 1 (a) is used (for example, Patent Document 1). The shell hanging pin usually has wedge-shaped locking portions that rise diagonally toward the central portion in the length direction of the pin at both ends and near the center. The locking portions at both ends prevent the shell from coming out of the pin, and the locking portion in the center prevents the pin inserted into the rope from being biased.

The aquaculture rope is pierced with shell hanging pins at regular intervals, and one or two scallops with holes in the ear pieces are hung on both sides of the pins protruding from the aquaculture rope. The shell hanging pin is usually made of resin. Generally, about 100 shell-hanging pins are inserted into one aquaculture rope at intervals of about 10 to 12 cm. At the time of shipment of scallops, the scallops can be removed from the shell-hanging pins by tearing the shell-hanging pins while pulling the aquaculture rope strongly with a special machine.

The shell-hanging pin remains on the culture rope from which the scallops have been removed, and it is necessary to remove the shell-hanging pin from the culture rope in order to reuse the culture rope. The work of removing the shell hanging pin from the aquaculture rope was once done manually, but there was a problem that the work was complicated and the workability was poor. For the purpose of solving such a problem, for example, as shown in Patent Documents 2 to 4, a device for automatically removing a shell hanging pin from a farming rope has been proposed.

In each of the devices proposed in Patent Documents 2 to 4, the shell-hanging pin is cultivated by pulling the culturing rope at a constant speed and sandwiching the shell-hanging pin from one side or both sides by a dedicated method. It is to be removed from.

The device proposed in Patent Document 2 is configured to sandwich the protruding portion of the shell hanging pin protruding from the aquaculture rope between the outer peripheral portion of the pulley and the belt. The sandwiched shell hanging pin is pulled out from the aquaculture rope by the force that the aquaculture rope is pulled by the tension transport mechanism.

The device proposed in Patent Document 3 is a device in which a drum-shaped rotor having a slit into which a protruding portion of a shell hanging pin can enter is rotatably provided in a cover. The shell hanging pin having the protruding portion in the slit is removed from the aquaculture rope by being pulled between the rotor and the cover by the rotation of the rotor.

The device proposed in Patent Document 4 is a shell-hanging pin from a farming rope by pulling a shell-hanging pin between a helical gear, a rubber roller, a resin roller, or the like and a side wall of a rope passage by rotation of the gear or the roller. Is to remove.

Japanese Unexamined Patent Publication No. 2015-198636 Japanese Unexamined Patent Publication No. 2006-115806 Japanese Unexamined Patent Publication No. 2009-1598772 Japanese Unexamined Patent Publication No. 2012-005357

In the prior art including the techniques shown in Patent Documents 2 to 4 described above, a gear, a rubber roller, a gear, a rubber roller, in which a shell hanging pin protruding from the aquaculture rope is arranged at any position around the transport path of the aquaculture rope. It is configured to be pulled out from the aquaculture rope by using a pull-out part such as a rubber belt or a pulley.

However, with these conventional techniques, only 80 to 90% of the pins can be removed, and there is a problem that residual pins are always generated. In particular, as shown in FIG. 2, the shell hanging pin is torn off by a strong force when the scallop is removed, so that the tip is extended and thinned (P1 in FIG. 2), or it is cut and shortened. (P2 in Fig. 2), bent near the aquaculture rope due to the weight of the scallops (P3 in Fig. 2), or deviated from the original mounting state (P4 in Fig. 2). In many cases, the scallop hanging pin is not removed from the aquaculture rope because the scallop hanging pin passes through without touching the pull-out portion, or the force is insufficient even if it is pinched in the pull-out portion.

Large fishermen may use as many as 5 million shell-hanging pins annually, and even mid-sized fishermen may use as many as 2 million shell-hanging pins. Even if 10% of the pins remain on the aquaculture rope when the shell hanging pins are removed by the conventional technique, the number is 200,000 to 500,000. The remaining shell-hanging pins have to be removed manually using pliers, which is a heavy burden for fishermen.

Further, when the aquaculture rope is wet or dirty, or when a plurality of aquaculture ropes are connected, it is difficult to use such aquaculture rope as it is by the prior art. In the prior art, dirty ropes need to be pre-cleaned and wet ropes need to be dried to some extent. Further, in the prior art, a step of setting the culture rope in the device is required, and the existence of the step is also one of the factors that reduce the workability of removing the shell hanging pin.

An object of the present invention is to provide a removing device capable of easily and surely removing all shell hanging pins from aquaculture rope.

In the above task, two rotating bodies having protrusions arranged non-linearly in the direction of the rotation axis, which are formed so as to bite into the shell hanging pin, are arranged as close as possible, and the shell hanging pin is inserted. This can be solved by running the aquaculture rope close to these two rotating bodies.

The present invention provides a shell-hanging pin removing device for removing a shell-hanging pin inserted in a rope from the rope. This device has a first rotating body and a second rotating body arranged in close proximity to the first rotating body.

It is arranged so as to be substantially parallel to the central axis of the first rotating body. One or both of the plurality of first protrusions and the plurality of second protrusions are arranged so as to be arranged non-linearly with respect to the length direction of the central axis of the first and second rotating bodies. .. The rope into which the shell-hanging pin is inserted is configured to run in close proximity to the first and second rotating bodies and approximately parallel to the central axis of the first and second rotating bodies, and therefore for aquaculture. The shell hanging pin inserted in the rope is inserted between the first protrusion and the second protrusion, and is pulled out from the aquaculture rope as the two rotating bodies rotate.

In one embodiment, the plurality of first protrusions are preferably arranged irregularly with respect to the central axis direction of the first rotating body, and the plurality of second protrusions are the second rotating body. It is preferable that they are arranged irregularly with respect to the central axis direction of. The first rotating body and the second rotating body are close to each other so that the distance between the first protrusion and the second protrusion when they are closest to each other is narrower than the thickness of the thinnest portion of the shell hanging pin. It is preferable that they are arranged. It is preferable that each of the plurality of first and second protrusions has a tip portion formed at an acute angle so as to bite into the shell hanging pin at the front portion in the rotation direction.

In one embodiment, the first rotating body has a first disk body and a plurality of first protrusions arranged at intervals in the circumferential direction on the outer peripheral surface of the first disk body, respectively. A plurality of first disks having the same can be formed as a first disk laminate formed by being laminated in the length direction of the rotation axis. Similarly, the second rotating body has a plurality of second rotating bodies, each of which has a second disk body and a plurality of second protrusions arranged at intervals in the circumferential direction on the outer peripheral surface of the second disk body. The second disk can be a second disk laminate formed by being laminated in the length direction of the rotation axis.

In one embodiment, the device may further include a protective section to protect the rope traveling in close proximity to the first and second rotating bodies from contact with the first and second rotating bodies. This is good. The protective portion has a gap formed so as to extend substantially parallel to the central axis of the first and second rotating bodies, and the gap is between the first rotating body and the second rotating body. It is preferable that it is arranged at a position corresponding to.

The protective portion preferably has two plate-like bodies, each of which has an edge extending parallel to the central axis of the first and second rotating bodies. The edges of the two plate-shaped bodies are arranged adjacent to each other with a gap and close to the first and second rotating bodies, and each of the plate-shaped bodies has a cross-sectional shape in the direction across the edges. It is preferable to have a substantially F-shaped shape.

In one embodiment, the device preferably further comprises a holding member for pressing the rope against the gaps in the protective section. The pressing member is preferably a rod-shaped member that extends in a direction that crosses the gap of the protective portion and can move in a direction away from the gap.

According to the apparatus according to the present invention, even a shell hanging pin that could not be removed by the prior art and remained on the culture rope can be reliably removed from the culture rope, so that the remaining pin can be manually removed after the fact. Since the removal step is not required, the work load can be reduced and the removal work time can be shortened. In addition, since this device has a simple structure, it does not require the pre-cleaning process that was required for conventional devices with a complicated structure, and even if it is a wet culture rope or a culture rope with foreign matter attached. , Can be used.

By flipping the lever 63 around the fulcrum 64 in the direction of the arrow, the pressing member 65 can be moved in the direction away from the aquaculture rope R.

[How to use the device]
Hereinafter, a method of using the shell hanging pin removing device 1 according to the present invention will be described.
FIG. 8 shows the usage state of the shell hanging pin removing device 1. First, the motor 3 of the shell hanging pin removing device 1 is operated to rotate the disk laminates 44a and 44b of the pin removing unit 4 in opposite directions. The direction of rotation is, for example, the direction of the arrows shown in FIGS. 6 and 8.

By tilting the lever 63 of the rope holding portion 6 in the direction of the arrow shown in FIG. 7, the holding member 65 is moved upward. After moving the pressing member 65 upward, the aquaculture rope R in which the shell hanging pin P is inserted is arranged along the gap 52 between the plate-shaped bodies 51a and 51b of the protective portion 5. Next, by returning the lever 63 of the pressing portion 6, the pressing member 65 is arranged so as to cross the aquaculture rope R. The culture rope R is pressed against the gap 52 by the force of the spring 62 of the pressing portion 6.

Next, the culture rope R is moved in the direction indicated by the white arrow in FIG. The aquaculture rope R is assumed to be moved by an operator in this embodiment. However, for example, a device for winding the aquaculture rope R is arranged on the downstream side in the moving direction of the aquaculture rope R, and a guide device for guiding the aquaculture rope R to the gap 52 of the protection portion 5 is arranged on the upstream side in the moving direction of the aquaculture rope R. By doing so, it is possible to remove the shell hanging pin P while automatically moving the aquaculture rope R.

When the culture rope R moves along the gap 52, the shell hanging pin P inserted into the culture rope R enters the gap 52 as shown in FIG. 6 (b), and the two disks of the pin removal unit 4 enter the gap 52. It is sent between the laminated bodies 44a and 44b. The shell hanging pin P sent between the disk laminates 44a and 44b is surely pulled out from the aquaculture rope R by the non-linearly arranged protrusions 444a and 444b of the disk laminates 44a and 44b.

That is, by arranging the protrusions 444a and 444b so as to be arranged in a non-linear manner and so as to be close to each other, for example, at a position where the tip portions 448a and 448b face each other, Both tip portions 448a and 448b bite from both sides of the shell hanging pin P and pull the pin P downward, and the protection portion 5 stops the aquaculture rope R which is exerted a downward force by pulling the pin P. As a result, the shell hanging pin P can be reliably pulled out from the aquaculture rope R. In another place, for example, at a position where the tip portion 448a of the disk laminate 44a and the valley 446b of the disk laminate 44b face each other, the tip portion 448a bites into the shell hanging pin P and the pin P is inserted into the valley 448b. The shell-hanging pin P can be reliably pulled out from the aquaculture rope R by pulling it downward while feeding it into the cage and stopping the aquaculture rope R to which a downward force is applied by the pin P being pulled. .. As described above, since the mechanism when the shell hanging pin P is pulled downward by the rotation of the disk laminates 44a and 44b varies in the length direction and the circumferential direction of the disk laminates 44a and 44b, the aquaculture rope. At any position between the movement of R and the movement of the shell hanging pin P from the front end to the rear end of the disk laminates 44a and 44b, the shell hanging pin P is surely removed from the aquaculture rope R. Become.

The shell hanging pin P removed from the aquaculture rope R falls downward from between the disk laminates 44a and 44b, and from the pin discharge port 23 provided in the housing 2 below the disk laminates 44a and 44b. , Is discharged to the outside of the device 1.
