Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flexible endless ring body, particularly a flexible endless hanging ring that can be easily connected to and released from an object, can provide sufficient tightening force, and has the required tensile strength. The present invention provides a method for manufacturing. For example, when setting up a seaweed cultivation net, attach several floating balls to the main net,
Work is carried out to expand appropriate areas of the main network. Floating balls usually require a distance of about 3m, so one side
For a 20m aquaculture net, nearly 30 floating balls would have to be attached to the main net at sea, and the bulky floating balls would need to be removed when transporting and storing the net. In the method of directly hanging the main net around the floating balls, the floating balls cannot be removed and are easy to break at the worn parts of the floating balls and the main net, so a separate tethering net is hung around the floating balls and this The method of tying it to a net is used, but if it is tied sufficiently so that it does not shift its position, it will be difficult to untie the knot when removing it. Attaching and removing these floats is difficult work, especially at sea in winter.
In order to make this process even a little easier, so-called satsuma processing is used to process the net into an annular shape, but not only does this process require considerable skill and time, but the diameter of the joint becomes thicker, and this part cannot be manufactured locally. Not only does this hinder workability, but the strength is inevitably reduced due to the binding of fibers. One of the main objects of the present invention is to construct a flexible endless hanging ring suitable for such uses using continuous yarn, and to produce an endless ring of arbitrary length, thickness, and strength relatively easily and economically. A method is disclosed.

The endless ring manufactured by the manufacturing method of the present invention is made by passing one end of the ring into the other end in the same way as in the case of satsuma processing, so-called chi-yoke hanging.
It can be easily attached by simply hanging the ring on the object and pulling it, and the stronger the tension, the stronger the binding.
Furthermore, since the two filaments are hung together, sideways shifting is prevented, and it can be easily removed by loosening the tension. In addition to the above-mentioned uses, the endless ring which is a feature of the present invention can be used, for example, to hook timber to a slider in work such as sliding timber cut from a mountain down a cable. It is also suitable for cases where

The details of the present invention will be explained below based on the drawings.

The endless rings 2, 2'... are all obtained by twisting continuous threads into an endless shape by the method of the present invention, and the length and thickness of the rings are determined by adjusting the device and depending on the continuous threads that are the raw material. The thickness of the strands and the number of twists are arbitrarily selected, and the number of twists of the final product is arbitrarily selected depending on the number of repetitions of the second step, third step, etc. described above. Also, the strength of the continuous yarn, the number of twists,
Design conditions such as the number of twists and layers are selected depending on the strength required by the final product, but these conditions are naturally set to the minimum from the viewpoint of strength efficiency, flexibility, and economy. Furthermore, in order to increase the durability of the product, it is desirable to perform waterproofing, oil-proofing, and/or wear-proofing treatment at an appropriate time.

The basic principle of the method of the present invention for producing endless rings is:
Forming a ring corresponding to the desired ring body circumference at the end of the continuous yarn, twisting the ring continuously with the yarn while rotating the ring, and stopping the rotation when the desired thickness is reached, A first step of cutting the continuous yarn and intertwining its ends by an appropriate method, such as sewing several times in the diametrical direction of the ring body, to form an endless ring of one strand made of endless yarn; The second step is to remove it from the circumferential thread, wind a part of the endless ring in a spiral shape, and form a second endless ring passing through it using the same operation. This process includes the third and subsequent steps for obtaining a ring.
The details of this method will be explained below based on the front model diagram, FIG. 6. Continuous yarn 1 wound on carrier 3
The terminal is pulled out through the tension adjustment part 4, and the nozzle 5, winding rollers 6, 6', circumference setting guide 7,
Mooring guide 8, adjustment guide roller 9, twisting mechanism 1
0 center, through the snail wire 3', and tied with the continuous yarn 1 near the nozzle 5 to form a ring shape. Next, the winding and feeding rollers 6, 6' and the twisting mechanism 10 are rotated in conjunction with each other, and the above-mentioned The continuous yarn 1 is supplied while going around the annular body and twisted at the nozzle point.The line connecting the nozzle 5 and the take-out point of the continuous yarn 1 is the nozzle 5.
The angle between the perpendicular line and the perpendicular line is approximately equal to the angle between the perpendicular line and the line connecting the nozzle 5 and the snail wire 3', but as the twisting progresses, the annular body returning to the nozzle 5 Since the snail wire 3' becomes thicker, it is desirable to move the position of the snail wire 3' accordingly and make the above two angles smaller. Note that the continuous yarn 1 itself is twisted by the rotation of the twisting mechanism, but if desired, the carrier 3
Adjust by rotating. The circumference of the annular body is
By moving the mounting position of the circumference setting guide roller 7 up and down, the circumference can be changed within a considerable range.
If more extensive changes are required, the roller 7,
The mooring guide 8 and the adjustment guide roller 9 may be used as one and moved to any horizontal position. The adjusting guide roller 9 not only changes the direction of the annular body, but also allows it to be moved up and down so that the tension during operation can be adjusted. Next, one important point in the manufacturing method of the present invention is that a part of the endless ring 2 formed in the first step is spirally wound, and the second endless ring 2'
For this purpose, a mooring guide 8 as shown in Fig. 7A is suitable, and Fig. 7B shows the endless ring 2 obtained in the first step being wound around the cylinder 8' in a spiral shape. The winding direction is naturally opposite to the twisting direction of the ring 2. To pass through this spiral winding to form the ring 2' in the second step, the end of the continuous thread 1 is hooked onto, for example, a needle-like jig and passed through the cylinder 8', as in the first step. Just form the first ring. The length of this cylinder 8' is determined by the amount of spiral winding, and the greater the amount (number of times) of spiral winding, the greater the number of twists when the spiral winding is stretched around the entire circumference of the completed endless ring. Although it will increase,
As is known from FIG. 7B, it is impossible in principle to spirally wrap the entire circumference of the ring 2, and furthermore, in the third step, as shown in FIG. It must be the same number as the number of spiral turns,
Similarly, the more steps are added, the thicker the base material to be spirally wound. Therefore, the number of initial spiral turns must be determined in advance. The cylinder 8' and the communication opening groove provided in the bottom plate 8'' for supporting the cylinder 8' are necessary in order to take out the ring body at the end of each process. Pry up the upper part of the ring (strand) and take it out from the opening groove in the straight part of the last manufactured ring (strand).

Providing such an opening groove in the twisting mechanism 10 is another important requirement for realizing the method of the present invention in which the formed ring body is easily taken out and subjected to the next step. FIG. 8 shows one configuration example of a suitable twisting mechanism 10.
The cylindrical bearing 11 is composed of a bearing 11' and a bottom plate 11'', and an opening groove communicating between the two is provided in the same way as the mooring guide 8, and the opening groove of the bottom plate 11'' matches the opening groove of the mounting frame 11 and is fixed. be done. gear 1
2 is provided with a bearing 12', the inner diameter of which is slightly larger than the outer diameter of the barrel 11' of the cylindrical bearing 11, and the gear 12 and the barrel 12' are also provided with a communicating opening groove. A movable tongue piece 15 is provided on one side of the gear 12.
is rotatably provided, and when the gear 12 rotates and the movable tongue piece 15 rotates in the direction of the rotation center of the gear 12, the side wall of the tongue piece that coincides with the tooth surface of the gear has a The same tooth pattern as the teeth is engraved, and the gear 1
The gear teeth of the tongue piece 15 compensate for the lack of gear teeth in the opening groove portion provided in the gear 12 and the tongue piece 15.
Smooth rotation is obtained by the intermediate gear 16 having a wall thickness approximately equal to the sum of the thicknesses of the intermediate gear 16. A cylindrical socket 13' is provided at the center of the rotating arm 13, and its inner diameter is slightly larger than the outer diameter of the shaft cylinder 12' of the gear 12. A key groove corresponding to the protrusion is provided. The rotary arm 13 and the cylindrical socket 13' are provided with communication opening grooves, just like the cylindrical bearing 11 and the gear 12. Note that a carrier 3 around which the continuous yarn 1 is wound and a tension adjustment section 4 are attached to one end of the rotating arm 13, and a snail wire 3' is attached to the other end, and the snail wire 3' is the same as described above. In order to match the twist angle when the ring body becomes thicker, it is desirable that the ring body be mounted so as to be movable in the direction of the center of rotation. Finally, cylindrical pin 1
4 is a cylinder whose outer diameter is slightly larger than the inner diameter of the shaft cylinder 11' of the cylindrical bearing.One part of the wall of the cylinder is cut in the longitudinal direction to make the diameter freely compressible. , rotary arm 13 are stacked and assembled in this order, and then the shaft cylinder 11' is assembled from above.
It is pushed into the shaft while compressing its diameter to form a shaft cylinder in which the gear 12 and the rotating arm 13 rotate. To take out the ring body after the process is completed, first pull out the cylindrical pin 14 from the shaft tube 11', widen the cut in the cylinder wall, remove it from the ring body through it, and then remove it from the ring body.
Next, the cylindrical bearing 11, the gear 12, and the rotating arm 13
If all the communication opening grooves of the ring body are aligned, the ring body can be easily taken out of the device. Of course, the width of these opening grooves is made slightly larger than the thickness of the ring of the final product.
Note that the nozzle 5 is split into two parts, so that one side can be removed by removing the bolt, so when removing the ring body, do this at the same time.

We have developed a method for producing a material that is extremely useful in industry, as it allows the production of a hanging ring that can be easily attached to an object and automatically tightened by pulling and pulling up, and that can be easily removed from the object after the work is completed. This is what we provide.
