Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention makes it possible to securely and firmly attach a sub-rope to a main rope made by twisting at least two or more single yarns together, and to automate the entire process. The possible attachment of the sub-rope to the main rope in a stranded form relates to a method.

(Problems to be Solved by the Invention) Conventionally, as well-known methods for attaching a sub-rope to a main rope, one end 18 of a sub-rope 12 is tied to an outer peripheral surface 17 of a main rope 9 as shown in FIG.
Alternatively, there is an attachment method in which one end 18 of the sub rope 2 is fastened to the outer circumferential surface 17 of the main rope 9 with a folding clasp 15.

However, in the above conventional method, if the knot or clasp 15 of the sub-rope 2 becomes loose, the sub-rope 2 becomes attached to the main row 19.
Since the sub rope 2 slips on the outer peripheral surface 17 of the main rope 9 and moves carelessly, there is a problem in that the sub rope 2 cannot be reliably fixed and attached to a predetermined location on the main rope 9.

Therefore, for example, in a fishing method where a large number of sub-rope fishing lines are attached to the main rope at predetermined intervals and suspended in the sea, if the fishing lines are attached to the main rope using the conventional method described above, the knots in the fishing lines will gradually loosen. This causes problems such as the fishing line slipping on the main rope, and as a result, the fishing line gets swept away by the current and comes to one end of the main rope, or the fishing lines get entangled with each other.

Furthermore, in the conventional method described above, the process of tying the sub-rope to the main rope is complicated and requires manual labor, so there is a problem in that the work efficiency is extremely low.

The present invention was invented in view of the above problems, and its purpose is to securely and firmly attach the sub-rope to a predetermined location on the main rope without causing any slippage, and to make the attachment process fully automated. The point is that it can be achieved.

(Means for Solving the Problems) The present invention achieves the above object by utilizing the fact that most of the main rope is composed of several single yarns twisted together to maintain its strength. It was invented to solve the problem, and the gist of its structure is that when attaching the subrow 12 to a part of the main rope 9, which is made up of at least two or more single yarns 8 twisted together, the attachment is At the same time or after compressing both sides 10a, 10b of the point 10 in the direction opposite to the original twist of the main rope 9, this attachment creates a gap 13 between the respective single threads 8 of the point 10, and then The sub-rope 2 is separately attached to the main rope 9 by inserting it into the gap 13 created at the point 10, and then the attachment is carried out by untwisting the point IO and connecting the end 4.4a of the sub-rope 2 to the main rope 9. Fold back toward the main body 2a side of the sub-rope around the end 4.4a of the sub-rope.
The sub rope 2 is attached to the main row 19 by integrally fixing the main rope 2a and the main rope 2a.

(Function) Therefore, in the method of attaching the sub-rope to the twisted main rope characterized by the above-mentioned configuration, the sub-rope is attached by holding down both sides lQa, 10b of the sub-rope attachment point 10 on the main row 19. 10 is twisted in the direction opposite to the twisting of the main rope 9 and compressed at the same time or after that, the attachment is performed so that the at least two twisted single threads 8 at the point 10 are untwisted and pushed outward respectively. Therefore, the above attachment can easily and smoothly create the gap 13 between the single yarns 8 at the location 10.

In addition, for the attachment that has occurred as described above, the sub rope 2 is separately inserted into the gap 13 of the point 10 so as to be perpendicular to the main rope 9, and then the attachment is done by untwisting the point 10, so that the sub rope 2 is connected to the main rope 9. The sub-rope 2 is integrally sandwiched between the twisted single yarns 8, 8, .

Furthermore, the end portion 4.4a of the sub-rope 2 is folded back around the main rope 9 to separate the end portion 4.4a of the sub-rope and the main body 2a.
In order to fix the sub-rope 2 integrally, the sub-rope 2 is tied around the single thread 8 of the main rope 9 in a substantially ring shape. Also, it is possible to reliably prevent the sub rope 2 from coming off from the main rope 9.

(Example) Hereinafter, embodiments of the present invention will be described according to an example shown in the drawings.

First, as shown in FIG. 1, the sub-roll 12 pulled out from the roll 1 is passed through the open cutter 3, then bent and transferred by 90 inches, and its one end 4 is clamped and fixed with the clamp 5.

Next, as shown in FIG. 2, the intermediate point 6 of the sub-rope 2 stretched between the cutter 3 and the clamp 5 is latched and pressed by a presser needle 7, and the sub-rope 2 is moved to the right in the figure.

At the right side position, a main rope 9 made of three single yarns 8 twisted together is stretched so as to be perpendicular to the transport direction of the sub rope 2, and the main rope 9 is connected to the sub rope as shown in FIG. One side 10a of the sub rope attachment point lO perpendicular to 2 is moved by the moving clamp 11, and the other side lOb
is clamped and fixed by a rotating clamp 12.

Then, to attach the sub rope 2 to the main rope 9, the sub rope 2 is moved straight to the point 10, and at the same time, as shown in FIG. said moving clamp 1
1 to the swing clamp 12 side. At this time, the single thread 8. is attached at point 10 by means of the pivoting clamp 12.
8... are untwisted, and at the same time the single yarns 8.8... are pushed outward by the pressure of the movable clamp 11, so that the twisted single yarns 8.8... at the location 10 are attached. A difficult gap 13 will be created between the two.

Then, the sub-rope 2 transferred by the pusher needle 7 is inserted into the gap 13 created in this way, as shown in FIG. He draws out 12.

After pulling out the sub-rope 2 to a predetermined length in this way, the cutter 3 is closed and the sub-rope 1 is pulled out as shown in FIG.
At the same time, the fixation of the clamp 5 is released, and the fixation of the movable clamp 11 and the swing clamp 12 to the main row 19 is also released, and both clamps 11 and 12 are returned to their original positions. At this time, the main rope 9
returns to its original twisted state, and the sub-rope 2 is integrally fixed between the single yarns 8, 8, and so on.

Thereafter, as shown in FIG. 7, both ends 4. of the sub rope 2.
4a to the sub rope body 2a with the main rope 9 as the center.
It is folded back to the side and both ends 4.4a are fastened to the sub-rope main body 2a with clasps 15.

After attaching the sub-rope 2 to the main row 19 as described above, the main rope 9 is transported a predetermined distance, and a new sub-rope attachment point 10 is set, and one end 4 of the sub-rope 2 cut by the cutter 3 is again The above-described installation starts the process again with a 90'' bend.

Then, the main rope 9, to which the sub ropes 2, 2... are attached at predetermined intervals, is moved to the roll 16 as shown in FIG.
It is then rolled up.

Therefore, according to this embodiment, all the steps can be performed in series by mechanical equipment without the need for manpower, so that the work efficiency can be dramatically improved.

In addition, the sub rope attached to the main rope is integrally sandwiched between the twisted single threads 8 and 8 of the main rope 9, so it may slip and move along the single threads 8. It can be reliably attached to the predetermined position of the main rope 9 without having to do anything.

Furthermore, both ends 4.4a of the subrow 12 are attached to the main rope 9.
Fold around the center and attach both ends 4.4a to the sub-rope main body 2a.
Since the sub-rope 2 is fastened with the clasp 15, the sub-rope 2 is tied around the single thread 8 of the main rope 9 in a substantially ring shape, so even if a great force is applied to the sub-rope 2, This will surely prevent it from slipping out from the main rope.

In the above embodiment, when transferring the sub-rope to the main rope, one end of the sub-rope is fixed and the intermediate point of the sub-rope is pressed and transferred with a presser needle. Without limitation, for example, one end of the sub-rope may be hooked with a pusher or the like and transferred to the main rope as it is.

In addition, the main rope is not limited to three single threads twisted together as in the above embodiment, but may be composed of at least two or more guard threads twisted together, and the material of the single threads is not limited. .

Furthermore, the means for attaching the sub rope on the main rope to create a gap at the point is to fix both sides of the point with clamps, twist it with one clamp, and then compress it with the other clamp, as in the above example. For example, twisting and compression may be performed at the same time, or twisting and compression may be performed using only one clamp, and the rotating angle of the rotating clamp may not be <180° as in the above embodiments. The angle can be arbitrarily set depending on the number of single yarns, the twisting state, etc. The point is that the attachment on the main rope can be done by pressing both sides of the part and compressing the part at the same time or after twisting the part in the opposite direction to the twisting of the main rope.

Furthermore, in the above embodiment, the end of the sub-rope is folded back and fastened to the sub-rope main body with a clasp, but in order to further strengthen the attachment, the end is wound around the main rope several times and then tightened. You may wear it.

Further, in the above embodiment, all the work processes are automated, but the present invention is not limited to this, and flexibility may be given to the work process by including manual work in some steps. You can also do everything manually.

In addition, the design of the material of the sub-rope, the specific configuration of each mechanical device when the present invention is carried out automatically, etc. can be changed within the intended scope of the present invention.

(Effects of the Invention) As mentioned above, the present invention focuses on the fact that most of the main ropes are made of single threads of Miki or more twisted together, and first, the sub-rope is attached to the main rope by holding both ends of the part. Attachment can easily create a gap between the single threads at the point by compressing the point at the same time as or after the twisting of the main rope in the direction opposite to the twist of the main rope, so that the sub-rope can be inserted into the gap. By inserting the single yarn, untwisting the single yarn, and folding and fixing the end of the sub-rope, the sub-rope is integrally sandwiched between the twisted single yarns and is firmly tied in a substantially ring shape. Therefore, the sub-rope can be securely and firmly attached to a predetermined location on the main rope, without the sub-rope slipping on the outer circumferential surface of the main rope and moving carelessly, or coming off even if a great force is applied to the sub-rope, as in the past. The conventional method of mounting, which allows the device to be fixedly attached, has achieved an extraordinary effect that was not possible at all.

In particular, the most important step of the present invention, which is the step of inserting the sub-rope between the single threads of the main rope, is easily and uniformly performed as described above, so it is possible to do so by operating a mechanical device. The entire process can be automated in a series, which has the effect of dramatically improving work efficiency.
