Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to seed insertion winding device and the winding method of laver network for winding the seaweed network long.
[0002]
[Prior art]
Nori culture is carried out by placing a laver net in the ocean. Therefore, before laver nets are stretched over the ocean, the laver nets are seeded. There are several methods for attaching seeds, but as a typical method, a large number of bags such as plastic bags are attached to a laver net, and oyster shells that are seeded with seeds are put into the bags in advance. It has been known. When the seaweed net thus seeded is stretched in the ocean, the seaweed seed attached to the oyster shell jumps out of the bag and adheres to the seaweed net. And this nori seed grows, and nori leaves used as raw materials, such as a sheet-like dry nori, are grown up.
[0003]
Conventionally, the introduction of oyster shells, which are seeds attached to bags, spreads a long belt-like laver net on land, and a large number of workers (generally about 20-30 people) are placed around this laver net. I was standing. When the oyster shell was put into the bag, the laver net was rolled into a roll and the rolled laver nets were loaded onto a laver ship and transported to the marine aquaculture site.
[0004]
[Problems to be solved by the invention]
The addition of oyster shells to the bag must be completed in a short time (preferably within 5 minutes). This is because if this takes a long time, the quality of the laver seed will deteriorate. For this reason, conventionally, as described above, a large number of people of about 20 to 30 are mobilized and the seeding operation is performed in a short time.
[0005]
Thus, since the conventional method has to mobilize a large number of workers, it requires a great labor cost and labor. In addition, as described above, when the seeding is finished, the laver net that has been spread out must be rolled up and rolled up, but it is difficult to roll the laver net into a compact roll, and the laver net is loose. It was inevitable that it was wound up. Therefore, the roll diameter of the wound nori net increased, and it was difficult to load on the nori ship. In addition, it takes time to wind in a roll.
[0006]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a laver net winding device and a winding method that can perform a laver net winding operation such as a seed putting operation in a short time with a small number of people.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a laver net winding device, FIG. 2 is a perspective view of a main part of the laver net winding device, FIG. 3 is a front view of laver net winding means, and FIG. FIG. 5 is a side view of the winding unit.
[0010]
In FIG. 1 and FIG. 2, a rod 2 is attached to a long belt-like laver net 1 with a pitch, and a large number of seed bags 3 such as plastic bags are attached. In FIG. 1, 5 is a wound body obtained by winding the laver net 1 in a roll shape. Reference numeral 6 denotes a wound body obtained by winding the laver net 1 fed from the wound body 5 into a roll shape by a winding means 20 described later. Note that the rod 2 and the bag 3 are not necessarily attached to the laver net 1.
[0011]
In FIG. 1, the wound body 5 is disposed in the placement portion 7. The arrangement portion 7 of the present embodiment is formed by adjusting an endless belt 9 on two pulleys 8 on the left and right sides, and the wound body 5 is arranged in a valley portion of the endless belt 9. Between the wound body 5 and the wound body 6, a shaft 10 serving as a guide for feeding the laver net 1 is horizontally disposed. The arrangement portion 7, the shaft 10, the winding means 20, and the like are attached to a frame (not shown).
[0012]
Next, the winding means 20 of the laver net 1 will be described with reference to FIGS. 2 and 3. Two winding means 20 are provided on the left and right so that both sides of the laver net 1 can be held. The winding means 20 includes a motor 21 as a power unit, a spline shaft 22 that rotates by being driven by the motor 21, a rotating body 23 attached to the spline shaft 22, a holding unit 24, and the like. The rotating body 23 is slidable in the width direction of the laver net 1 along the spline shaft 22 (see arrow A in FIG. 3).
[0013]
A plurality of (two in this embodiment) pins 25 protrude from the front surface of the rotating body 23, and the pins 25 are removably inserted into holes 26 formed in the back surface of the holding portion 24. The rotating body 23 and the holding unit 24 are detachably connected. A plurality of pin-shaped retainers 27 (two in this embodiment) protrude from the front surface of the retaining portion 24. In the present embodiment, a rotating unit that rotates by driving of the motor 21 is configured from the rotating body 23, the holding unit 24, and the like.
[0014]
As shown in FIG. 3, both end portions of the rod 2 are inserted between the holders 27 and held by the holding portion 24. The rotating body 23 can be moved forward and backward along the spline shaft 22. However, if the rotating body 23 is separated from the holding portion 24 by retracting the rotating body 23 toward the motor 21, the retainer 27 is moved to the rod body 2. It is possible to remove the holding portion 24 from the rod body 2 by pulling it out from the end portion of the rod body 2. As will be described later, desirably, the rod body 2 serves as a winding shaft when the laver net 1 is wound by the holding portion 24.
[0015]
It is conceivable that a winding shaft driven by the motor 21 is provided separately without using the rod body 2 as a winding shaft, and a laver net is wound around the winding shaft. In this case, when the winding (seeding) is completed, the winding shaft must be pulled out from the center of the roll-shaped laver net wound around the winding shaft, which is troublesome and difficult. On the other hand, if the rod body 2 is used as a winding shaft for the laver net 1, such a pulling operation is unnecessary, and it is only necessary to remove the holding portion 24 from the rod body 2, which is extremely advantageous in terms of operation.
[0016]
In this embodiment, two motors 21 are arranged on the left and right. However, the number of motors is one, and the rotation of this motor may be made to rotate the two right and left holding parts 24 by a transmission belt or the like. Well, the motor transmission system can be designed freely. Further, the specific structure of the holding portion is not limited to the present embodiment, but the end portion of the rod body 2 is inserted / removed between the holders 27 composed of a plurality of pins as in the present embodiment. With this structure, the holding portion 24 can be easily attached to and detached from the rod body 2.
[0017]
Further, as shown in FIG. 2, coupling means such as a string 15 or a hook may be provided on both sides of the laver net 1 and the both sides of the laver net 1 may be held by the holding unit by this coupling means. Such a coupling means may be provided on the holding portion side so that the laver net is coupled and held. Moreover, you may hold | maintain both sides of the laver net 1 directly with a holding | maintenance part. As described above, the holding unit may indirectly hold both sides of the laver net 1 via the rod 2 or directly hold both sides of the laver net 1 without the rod 2. The holding mode of the both sides of the laver net 1 by the holding part may be freely determined. However, in any case, as described above, it is desirable to use the rod 2 as a winding shaft of the laver net 1.
[0018]
In FIG. 1, reference numeral 40 denotes a wound body of a rope 41 as a string-like body. The rope 41 is unwound from the wound body 40, and is supplied onto the laver net 1 around the rolls 42, 43, 44 that are guide portions. The roll 43 serves as a tension applying unit that applies tension to the rope 41. The roll 43 applies tension to the rope 41 by its own weight or the spring force of a spring (not shown). If tension is applied to the rope 41 in this way, the rope 41 can be easily wound together with the laver net 1. The winding body 40, the rolls 42 to 44, and the like constitute supply means for the rope 41 that is a string-like body. Of course, the supply means of the string-like body is not limited to that of the present embodiment.
[0019]
In FIG. 2, the tip of the rope 41 is attached to the tip of the laver net 1 or the like. Reference numeral 45 denotes an attachment portion. The tip of the rope 41 may be attached to the rod 2 or the like. The rope 41 is preferably on the center line in the longitudinal direction of the laver net 1, supplied along the longitudinal direction of the laver net 1, and taken up by the winding means 20 together with the laver net 1. In the state where the winding is completed, the rear end portion 41 ′ of the rope 41 extends outward from the wound body 6 of the wound nori net 1 as shown in FIG. The wound body 6 obtained by winding the laver net 1 in a roll shape is transported to the ocean by a ship and stretched on the ocean. In this case, the operator holds the rear end portion 41 'in his hand, If the roll-shaped wound body 6 is rewound, the operator can unfold the laver net 1 in a sheet shape on the ocean without difficulty.
[0020]
In FIG. 4 and FIG. 5, two short tubes 28 are mounted on the front surface of the holding portion 24 so as to hold the holding element 27 therebetween. Reference numeral 50 denotes an abutting member, one end portion of which is a two-legged mounting portion 51 which is detachably inserted into the short tube 28, and the other end portion is bent into a key shape. The contact portion 52 is formed. The projecting length L from the winding center NA of the contact member 50 can be freely adjusted by changing the insertion depth of the mounting portion 51 into the short tube 28 so as to correspond to the winding diameter of the laver net 1. It has become. That is, the contact member 50 is attached to the rotating part including the holding part 24 so that the protrusion length L can be adjusted.
[0021]
As shown in FIG. 5, if the winding diameter D of the laver net 1 becomes larger during the winding of the laver net 1 by the winding means 20, the winding operation of the laver net 1 is interrupted and the short pipe 28 is The mounting part 51 is inserted, and the contact part 52 is brought into contact with the outer peripheral surface of the laver net 1 during winding. Then, the winding operation is resumed, and the laver net 1 is further wound on the contact portion 52. When the winding of the laver net 1 is completed, the mounting portion 51 can be removed from the short tube 28, and the abutting portion 52 can be easily pulled out from the laver net 1 wound in a roll shape.
[0022]
The reason for mounting the contact member 50 is as follows. That is, in FIG. 5, when the total length of the laver net 1 is long and the winding diameter of the wound body 6 wound around the winding means 20 is increased, the winding force by the holding portion 24 is applied to the central shaft portion of the wound body 6. It becomes concentrated and the central axis portion is strongly squeezed, making it difficult to wind the laver net 1 further. Therefore, by installing the contact member 50 in the middle of the winding operation as described above and thereafter winding it on the contact portion 52, the laver net 1 can be removed even if the winding diameter is increased. It can be wound smoothly. Of course, specific examples of the abutting member and the mounted portion are not limited to the present embodiment, and in short, if the winding diameter of the laver net increases, it can be further wound on it. That's fine.
[0023]
This laver net winding device has the above-described configuration, and the seeding method will be described next. First, in FIG. 1, the worker H feeds the tip of the laver net 1 from the wound body 5, rotates the shaft 10, and holds both ends of the leading rod body 2 with the retainers 27 of the holder 24 ( (See also FIG. 3). This leading rod 2 serves as a winding shaft for winding the laver net 1. Of course, as described above, both sides of the laver net 1 may be directly held by the holding part without using the bar 2, and in this case, the bar 2 also winds the laver net 1. It becomes a winding shaft.
[0024]
Next, the worker H is located in the vicinity of both sides of the laver net 1. The number of workers H is, for example, about 2 to 4 people. Therefore, the laver net 1 is slowly wound while the motor 21 is driven to rotate the holding portion 24. In this case, the rope 41 is also wound together with the laver net 1.
[0025]
In this way, while slowly winding the laver net 1, the worker H puts the oyster shell K to which the laver seed is attached into the bag 3. As the winding diameter of the laver net 1 increases, it is desirable to control the rotational speed of the motor 21 so that the rotational speed of the winding means gradually decreases. In this way, the laver net 1 is kept at a constant speed. Alternatively, the seeding operation can be performed while winding at a substantially constant speed. When the winding diameter of the laver net 1 is increased, the contact member 50 is mounted as described above during the winding operation, and the laver net 1 is wound on the contact part 52.
[0026]
In FIG. 1, when the laver net 1 is wound while the wound body 6 is rotated in the arrow B direction, the wound body 5 is rotated in the arrow C direction. Here, if there is no arrangement | positioning part 7, the winding body 5 will roll to the side (arrow D direction) because of the reaction force of the feeding of the laver net 1 to this arrow C direction. Therefore, in the present embodiment, the winding body 5 is arranged in the valley portion of the endless belt 9 of the arrangement portion 7 to prevent the winding body 5 from rolling in the direction of the arrow D so that stable work can be performed. ing. That is, the endless belt 9 of the arrangement portion 7 also serves as a rolling prevention means for preventing the wound body 5 from rolling sideways.
[0027]
When the laver net 1 is wound up and the seeding is finished, the holding portions 24 are removed from both ends of the rod 2 or both sides of the laver net 1. The contact member 50 is also extracted from the roll-shaped laver net 1. Then, the wound body 6 of the laver net 1 wound in a roll shape is loaded on a laver ship, transported to the ocean, and stretched on the breeding ground. In this case, as described above, the operator holds the rear end portion 41 ′ of the rope 41 extending from the wound body 6 of the laver net 1 in his hand and reverses the wound body 6 while rewinding. The seaweed net 1 is developed into a sheet in the ocean.
[0028]
In each figure, the laver net 1 is wound up by the winding means 20, but the laver net 1 is rolled up to form a roll-shaped wound body 5. The laver net 1 may be wound while being wound by the winding means 20, and in this way, the efficiency of the seeding work is greatly improved.
[0029]
FIG. 6 is a side view of an arrangement portion of a wound body according to another embodiment of the present invention, and shows another form of rolling prevention means. The placement portion 30 is formed by protruding a stopper 32 having a triangular cross section on a base plate 31 on which the placement portion 30 is placed. Therefore, the stopper 32 prevents the wound body 5 from rolling laterally (in the direction of arrow D) during the above-described seeding operation. Thus, various design changes are possible for the present invention.
[0030]
Further, the method of using the laver net winding device of the present invention is not limited to the above-described embodiment, and can be used for maintenance such as repair of laver nets in addition to the above-mentioned seeding. In this case, in FIG. 1, the operator is located on the side of the laver net wound by the winding means and repairs the broken laver net. Of course, in this case, the rods and bags need not be attached to the laver net.
[0031]
【The invention's effect】
As described above, according to the present invention, the seeding operation can be performed in a short time by a small number of people while winding the laver net. It can also be used for many purposes such as maintenance work for laver nets. Further, by winding the string-like body together with the laver net, it is possible to easily develop the laver net in the ocean. Further, by providing the abutting member, even when it is a long laver net and its winding diameter becomes large, it can be smoothly wound up.
