Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for bundling young scallops and other shellfish for cultivation.

Cultivation of scallops, etc. is carried out as shown in Figure 1, which is called the ear hanging method.

First, on a rope f1 with a length of about 7 to 8 m, two young shellfish 2 are placed in each location at intervals of about 0 to 15 cIn, and each rope has about 120 to 140 pieces. Two young shellfish are tightly attached.

The upper ends of the ropes 1 to which the young shellfish 2 are tightly attached are each tightly attached to the horizontal rows 13 provided below the sea surface S, and the ropes 1 are tied at approximately 250 mm intervals at approximately 70 mm intervals.
The horizontal rope is vertically installed, and both ends of the horizontal rope have 4 weights each at the lower end.
It is supported by a vertical rope 4 and an inclined rope 5 provided with a + 5 a, and a floating ball 6 is tightly attached to the horizontal rope to give it buoyancy. The young shellfish layered in the above device are then grown by plankton in the sea and cultured until they reach a predetermined thickness.

However, the work of tying 2 tons of young shellfish to the rope 1 was mostly done by hand, resulting in extremely poor work efficiency, and moreover, the work had to be completed between December and April, which is not suitable for aquaculture. Most of the winter was spent on this work, and improvements were strongly desired.

In other words, the conventional binding method, as shown in Figure 2, is to use a rope l that creates a gap when untwisted, and to insert the rope 7, which has been cut to approximately 30 cWL, into the untwisted gap. Wind the rope around knot 7.
A is provided and its central portion is tied to the rope 1.

Next, one end of the ear 2a of the young shellfish 2 is drilled,
The young shellfish 2 are tied to the rope 1 by inserting both ends of the strings 7 into the holes of the young shellfish and providing knots 7b and 7b, respectively, to prevent the young shellfish 2 from falling off.

On the other hand, when removing the grown shellfish from the rope, a special handling tool (not shown) is attached to the rope 1, and by pulling one end of the rope, the claws 7 are torn off.

In this case, the rope 1 is used repeatedly for many years, but because the knot 7a in the center remains, it cannot be removed by simply pulling it out, and the rope 7 cannot be removed by untying or cutting. It wasn't easy.

Moreover, seaweed and other small shells adhere to the extra prongs protruding from the tips of the knots 7b and 7b, and the knots 7a and 7b, which eat plankton and hinder the growth of the cultivated scallops. There were various drawbacks.

Therefore, the present invention is aimed at improving the drawbacks of the conventional type, and involves perforating one end of the ear of the young shellfish and the rope, respectively.
The present invention is a method for binding young shellfish to a rope by inserting a wire such as a wire rod into the hole and joining both ends of the wire to form a ring, and a device for automatically performing this method.

This not only dramatically improves the efficiency of tying, but also allows you to easily pull out the remaining strands from the rope after handling the grown scallops, and removes excess strands and knots. Therefore, it is an object of the present invention to provide a method and apparatus that can be expected to have effects such as alleviating the factors that hinder the growth of scallops due to the above-mentioned reasons.

Embodiments of the present invention will be described below with reference to the drawings.

A support 12 is erected on the base 11, and a base plate 13 is integrally attached to the support.

The pace plate 13 is provided with a rope 1 in the horizontal direction.
A guide tube 15 for guiding the rope 14 is provided.
A device is provided on the tip side where the young shellfish 16 are moved intermittently to a length corresponding to the interval at which the young shellfish 16 are bound.

Although not shown, the device is equipped with two gripping pieces that can be opened and closed using, for example, a cylinder, and these gripping pieces grip both sides of the rope and advance the gripping pieces in the horizontal direction using a special cylinder that has been tied in one place. Then, the q-de is pulled, and after moving forward a predetermined distance, the gripping piece is opened, and the gripping piece is moved back to its original position, and the gripping piece grips the rope again.

In addition to the cylinder, the above-mentioned device can be achieved by various structures using known means such as a rack and pinion that are linked together overnight.

Next, a punching device is provided in the center of the base plate 13.

The apparatus includes a rotating drill 17a and a guide member 17b' for guiding the drill, and the drill is moved up and down perpendicularly to the passage of the rotor 14 by suitable lifting means (not shown).

Next, adjacent to the path of the rope 14, a device for storing young shellfish 16 is provided. This device has each pedestal 18 formed with a curved surface that fits the surface of the shellfish so that it is easy to place two young shellfish on each.
．． 19, and a backing plate 20 for supporting these pedestals and for positioning by bringing the edges of the shell into contact. In this case, the positional relationship is to place two young shellfish on each pedestal.
8.19, the rope 14 is placed in parallel in such a way that it is clamped between the ears on one side of exactly two young shellfish,
Furthermore, the drill 17a is configured to descend exactly to the ear on one side of each young shellfish.

The apparatus for storing young shellfish 16 may include a pedestal 18 as necessary.
．． A mechanism for sliding the shell 19 is provided to ensure accurate positioning depending on the size of the shell, and a holding mechanism such as a spring means is provided to prevent the shell from moving during drilling.

Next, a device for intermittently feeding out a wire rod to a predetermined length is provided across the path of the rope 14 and facing the drill 17a. The device includes a guide tube 22 that guides the tube 21;
Although not shown, a mechanism having almost the same structure as the device for intermittently moving the rope 14 is provided, and is linked to the rise of the drill 17a into the hole of the young shellfish 16.16 and the low f14 drilled by the drill 17a. Then, a wire rod such as a wire rod 21 is fed out to a predetermined length and inserted.

Next, a guide device is provided that guides the distal end of the thread 21 inserted into the perforation in an arc shape so that it overlaps the proximal end. The device includes an engaging rod 22 having a concave portion 22ae at its tip, and a pinion 23a carved in a part of the curved surface of the engaging rod 22.
A rotary cylinder 23 that rotates along the outer periphery of a guide cylinder 15 connected to the base of the rack 24 that meshes with the pinion 23a that is given reciprocating motion by a cylinder (not shown) or the like.
It is made up of.

The distal end portion of the engaging rod 22 including at least the recessed portion 22a is formed of a conductive material, and the distal end of the barb 21 inserted through the perforation is projected into the recessed portion. As the rack 24 moves forward, the engagement rod 22 rotates about 180 degrees while guiding the thread 21 engaged in the recess 23a in an arc through the rotary cylinder 23 equipped with a pinion 23a that engages with the rack 24, and the proximal end of the thread is rotated approximately 180 degrees. Polymerize on the side.

As another embodiment of the guide device, for example, although not shown, a guide member made of synthetic resin or the like having a guide groove may be provided along the arc shape.

Next, a device for joining the polymerized wires will be explained.

At the position where the engagement rod 22 is rotated approximately 180 degrees, there is a recess 22a.
An electrode rod 25 is provided with a convex portion 25a that fits into the electrode rod 25. At least the tip of the electrode rod 25 including the convex portion 25a is made of a conductor, and the rest is made of an insulator, and an electrode piece 26 made of the same conductor is provided on the insulator side.

A predetermined voltage is applied between the electrode piece 26 and the conductor portion at the tip of the electrode rod 25.

Further, at the position where the engaging rod 22 rotates and comes into contact with the electrode rod 26, the concave portion 22a made of a conductive material and the convex portion 25jL formed at both ends are fitted, so that the engaging rod 22 The electrode piece 26 and the tip of the electrode rod 25 are short-circuited and energized via the electrode piece 26 and the tip of the electrode rod 25.

Therefore, the overlapping wires 21 held between the recess 22a and the protrusion 25a are heated and fused by the electric current.

It should be noted that the time required for contacting and fusing the locking rod 22 with the electrode rod 25 is determined, and after this predetermined time, the cylinder (not shown) moves the rack 24 backward, so that the locking rod 22 returns to its original state. It is configured to rotate and return to the position. Other examples of joining wire rods such as wire rods include attaching an appropriate amount of adhesive and joining the wire rods, or attaching other joining members to join the wire rods.Next, by the above-mentioned fusion bonding, 2 young shellfish 16.16 and rope 14
A device for cutting this annular portion from the side from which the string is fed out will be explained.

In this embodiment, as the device, a cutter 27 is installed adjacent to the feeding portion of the thread 21.

As a result, when the rope 14 is towed by the device for transferring the rope 14 explained at the beginning, the rope 21 is moved to the cutter 27.
It will be cut at

The cutter may be provided on the bottom of the backing plate 20, and instead of cutting the rope by the traction force when pulling the rope as described above, a movable cutter may be attached to the bottom of the backing plate to cut the rope. It is also possible to consider a configuration in which it is cut off before being towed.

Although a detailed explanation will be omitted, the following steps are performed: the descending movement of the drill 17a, the upward movement of the drill 17a after drilling, the feeding out of the thread 21, and the movement of the rack 24 for superimposing the tip of the thread 21 inserted into the hole toward the proximal end side. A series of operations such as forward movement, backward movement of the postmortem rack 24 that has been thermally fused, and pulling of the rope 14 to which the young shellfish are tied are performed by hydraulic or pneumatic equipment and motors that drive them, and electricity that controls them. This is done by a circuit.

In this case, it goes without saying that it is possible to select and implement the series of operations as appropriate whether to repeat them as 1 kl cycles or to complete them every 1 cycle.

The device of the present application is as described above, and its operation will be explained next.

First, pass the rope 14 through the guide tube 15, and
The tip of the rope 14 is gripped by a gripping piece of a device (not shown) for transferring the entire rope across the rope 14.

Next, after each of the two young shellfish 16, 16 is mounted on the pedestal 18, 19, the start switch of a series of electric control circuits is turned on.

In this case, for example, two sets of microswitches are provided in a part of the device for storing young shellfish, which are activated by each young shellfish being accommodated.
The start switch may be turned on when both microswitches are activated.

When the start switch is turned on, the motor is started to rotate the drill 17a, and the elevating means moves the drill 17a down to drill holes in the young shellfish 16 and the row f14, respectively, and then the drill 17a moves up again.

Then, in conjunction with the upward movement of the drill 17a, the device for feeding out the wire rod is operated, and the thread 21 is fed out a predetermined length and inserted into the hole, and its tip is attached to the recess 22 of the engagement rod 22.
protrudes into a. At this point, a cylinder (not shown) that drives the rack 24 is activated, and when the rack 24 is advanced, the rotating cylinder 23 provided with the meshing hinion 23a and the engaging rod 22 connected thereto rotate about 18,011 times. The tip of the barb 21 protruding into the recess 22a is guided in an arc shape in a locked state, and when the engagement rod 22 abuts the electrode bar 25, it overlaps with the proximal end of the barb 21.

The voltage applied between the electrode piece 26 provided on the electrode rod 25 and the convex portion 25a of the electrode rod made of a conductive material is conducted through the recessed portion 22a of the engaging rod also made of a conductive material, and the energization is conducted. The stream heats and fuses the polymerized tegus.

The engaging rod 22, which had been in contact with the electrode rod 25 for the time required for the fusion, returns to its original position as the rack 24 moves backward, and at this point, a cylinder (not shown) that moves the rope 14 is driven. When the rope is pulled to a predetermined length, the feed side of the thread 21 is cut by the cutter 27.

As a result, as shown in FIG.
16.16 pieces of young shellfish will be tied together in a ring shape with tegus 21.

Thereafter, by repeating the same operation, two young shellfish are bound at each predetermined interval of the rope.

In this embodiment, two young shellfish are tied at one location, but it is also possible to tie one shell or three or more at one location, if necessary.

According to the above-described invention, all this type of binding, which was conventionally done manually, can be done automatically, so work efficiency is dramatically improved, and this surplus time can be used for other tasks. Therefore, it can contribute to increasing the income of aquaculture farmers and ensure stable quality. In addition, unlike the conventional method, there are no extra wires that remain unless cut later to make three knots and knots at both ends, so plankton are eaten by seaweed and other small shells that attach to these wires during aquaculture. The growth of cultured shellfish is not hindered.

Furthermore, when handling a grown shellfish to remove it from the rope, since there is no knot and the wire is simply inserted, the wire can be easily pulled out from the rope, improving work efficiency and making it easier to use the rope repeatedly. can be easily done.
