Detailed Description of the Invention [Industrial applications]

TECHNICAL FIELD The present invention relates to a cord tying method and a device for tying a string of ropes, cords, and the like, which can be continuously provided with a “hitoe knot” knot.

[Prior art and its problems]

A string-like object such as a rope or a string in which a "hitoe knot" knot is continuously provided is used in various fields.
For example, it is used as an escape rope in an emergency such as a fire. In this case, the knot becomes a catch when caught on the rope, so there is an advantage that it can be safely escaped without the risk of slipping off. Further, in order to improve the quality of fruits such as mandarin oranges, it is also used as a hanging string for lifting the branches of fruit trees to improve the sun exposure to the fruits. In this case, hang a string provided with a knot from a hanging rope erected above the fruit tree, hang one end of the hook on the knot and hang the other end of the hook on a branch, Since the knot is continuously provided, there is an advantage that the hanging height of the branch can be arbitrarily set by re-hooking the hook. However, since the work of continuously providing the knots on the string has conventionally been performed manually, it is troublesome and inefficient. For this reason,
Especially in the case of a string for hanging a branch, instead of providing a knot on the string, a method of applying molten resin at an appropriate interval and curing it to make a continuous hump was sometimes taken, There was a problem that it was difficult to make a uniform hump and the cost was high.

[Purpose of the present invention]

It is an object of the present invention to provide a device capable of mechanizing the work of continuously providing a string-like knot of a string. Further, this makes it possible to inexpensively mass-produce a string-like object having a continuous knot.

(Operation) FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, and FIG. 8 are explanatory views showing a process of hooking a string on a winding tube. Each of FIGS. 3 to 8 shows the apparatus according to FIG. 1 as viewed from the opposite side. FIG. 9 is a plan view of an essential part showing how the string-like object is engaged, and FIG. 10 is an explanatory view showing a final step for obtaining the string-like object in which knots are continuously provided. The operation of this embodiment will be described with reference to FIGS. The front side of the string 5 is passed through the guide rings 233 and 234, and further inserted into the feeding pipe 216 of the crank plate 214, and the tip end side is the winding pipe 10.
It is easily tied to the tip of the. Also, the string 5
In this state, the tension of required strength is applied in the direction of arrow t. The drive shaft 220 is driven to rotate the disks 223 and 226 at the same rotational speed in the direction of arrow x in FIG. 2, and the hooking recess 229 of the string hooking plate 227 causes the leading end of the feeding pipe 216 of the crank plate 214 to orbit. Position so that it corresponds to the plane. (See FIG. 3) The drive shaft 210 is driven, the disk 212 is rotated, and the crank plate 214 is rotated in the arrow y direction. At this time, since the front end side of the string-like object 5 is tied to the winding tube 10, the string-like object 5 is unreeled from the unreeling tube 216 while being hooked into the hooking concave portion of the string hanging plate 227.
It is wound once around 229, and the crank plate 214 stops at a predetermined position. (See FIGS. 3 to 4) The drive shafts 220 and 225 are driven to rotate the disks 223 and 226, and the string hooking plate 227 rotates in the arrow z direction while hooking the string-like object 5 in the hooking recess 229. . At this time, since there is a slight gap between the string hook plate 227 and the tip end of the winding tube 10 so that the string object 5 cannot pass through, the string object 5 is the male screw portion of the tip end of the winding tube 10. It is wrapped around 13. (See FIGS. 5 to 6) When the string hook plate 227 is further rotated in the direction of arrow z,
Is released from the hook recess 229, and the knot portion of the string 5 is tightened by the tension in the direction of the arrow t shown in FIG. (7th

It is pushed into the space 141 between the outer tube 14 and the outer tube 14, and the knots are sequentially aligned. Also, handle 19
Are sequentially rotated in a predetermined direction to rotate the winding tube 10. At this time, since the overlapped portion 50 has entered the feed groove portion 140 of the outer tube 14, the string-like object 5 wound around does not rotate in the circumferential direction, and only the wound tube 10 rotates. As a result, the cord-like material 5 wound around is fed to the base end side of the winding tube 10 by the feeding action by the rotation of the male screw portion 13. By repeating the above steps 1 to 5, the cord-like material 5 is wound around the winding tube 10 as shown in FIG. Then, the overlapping portion 50 of the string 5 enters the feeding groove portion 140 as shown in the figure. After the certain amount of the string-like object 5 is wound, the string-like object 5 is cut on the front side of the feeding pipe 216. Then, the pull-out member 6 having the hook 60 at the tip end is inserted into the hollow portion 100 from the base end side of the winding tube 10 and the tip end of the cut portion of the string 5 is bound to the hook 60. Then, the handle 19 is rotated in the opposite direction to the above to rotate the winding tube 10. Also at this time, similarly, since the overlapping portion 50 has entered the feeding groove portion 140 of the outer pipe 14, the wrapped string-like object 5 does not rotate in the circumferential direction, and only the winding pipe 10 rotates. As a result, the wound string-like material 5 is sent to the tip side of the winding tube 10. at the same time,
As shown in FIG. 10, when the pull-out member 6 is pulled out toward the base side of the wrapping tube 10, the knots 50 are continuously formed on the string-like object 5 at substantially constant intervals. The present invention is not limited to the illustrated embodiments, and various modifications can be made within the scope of the claims.
