Abstract

PROBLEM TO BE SOLVED: To mechanize binding of two times by using one piece of string. SOLUTION: While a ring of one or more winds is being formed by means of one guide, guides 6 are caused to intersect each other, and further the guides 6 are twisted so as to be wound round each other. A predetermined part of the guide 6 is cut to provide a gap, while the forward end of a piece of string A is gripped so that the string A is pulled along the guides 6 so as to intersect as is the case with the guide 6 and is twisted and drawn out of the gap, thereby forming first binding. In the following step, two guides A18 are twisted so as to be wound round each other, each guide A18 is cut at a predetermined point to form a gap A, and a piece of string B24 having the first binding is grasped at a predetermined point. Each point of the string B24 grasped is pulled along each guide A18 and intersects as is the case of each guide A18 and is twisted so as to be pulled out of the gap A, thereby forming a second binding.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to tying a string in the field of packaging.

[0002]

2. Description of the Related Art Double tying of a string according to the present invention has conventionally been performed manually.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the labor that has conventionally been done manually.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to form a loop of one or more turns with one guide, cross the guides, and twist the guides so that the guides are wound around each other. , Make a gap by cutting a predetermined part of the guide, grasp the end of the string that is continuously connected, the string is pulled along the guide, intersect like the guide, twisted, and slipped out of the cut gap Then, the first tying is performed, and in the next step, the two guides A are crossed, twisted so that the guides A are wound around each other, and a predetermined portion of each guide A is cut to form a gap. First, each predetermined portion of one string having a first string knot is grasped, and each portion of the grasped string is pulled along each guide A, and each guide A
Crosses, twists and escapes from the cut gap,
This is to perform the second tying.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a wire 3 is passed through a tube 2 which bends freely, and a grip 1 is attached to the tip of the tube. A string grip portion in which the string 4 is sandwiched between the grip fitting 1 and the tube 2 so that the string 4 can be gripped. Next, as shown in FIG. 2, there is a guide 6 in which a notch 7 is open so that a part of the pipe is cut and a string that has entered the pipe is removed. The guide 6 is provided with a leaf spring 8 that repels the cord with a predetermined force so that the string does not come off from the point 7. The metal fitting 1 and the tube 2 can be moved by grasping the inside of the pipe. As shown in FIG. 3, in the first tying device, the guides 6 are crossed while making one or more loops with one guide 6, and further twisted so that the guides 6 are wound around each other. A gap 9 is made by turning the guide so that it faces outward from the center of the ring, and cutting a predetermined portion of the guide 6. Next, as shown in FIG. 5, the grip fitting 1 and the tube 2 are inserted from one end 10 of the guide 6, and the guide 6 is inserted.
, The string A15 pulled out from the opposite end 11 and pulled by the string supply / cutting means 14 is gripped by the grip 1 and the tube 2. The grip A is gripped by the grip 1 and the tube 2 along the guide 6. The string A 15 is pulled by returning to one end 10, and the string A 15 intersects the guide 6 while being pulled inside the guide 6, and is twisted so as to wind around each other.
Through the notch 7, and also through the cut gap 9 of the guide 6, and cut by the string supply cutting means 14, and the string A1
5 can make the first knot in the loop of the guide 6 as shown in FIG. Next, as shown in FIG. 7, in the second tying device, two guides A18 having the same shape and action as the guide 6 in FIG.
18 are wound around each other so that one end A20 of each guide A18 is opposite to each other, and each opposite end A21 of each twisted guide A18 is 90 ° from each other.
The guide A18 is bent in the same direction, and a predetermined portion of each guide A18 is cut to form a gap A19. As shown in FIGS. 8 and 9, each of the grip fittings 1 and the tube 2 are put into each of the guides A18 from one end A20, and are put out from the opposite ends A21 of each of the guides A18. In the middle of the string, the first tied string B24 is gripped at predetermined points of the string B24 supplied by the string transfer means 26 with the gripping metal fittings 1 and the tube 2, respectively. Each gripper 1 and tube 2 are connected to one end A along each guide A18.
20, each portion where the string B24 is gripped is crossed in the same manner as each guide A18 while being pulled through each guide A18, twisted so as to be wound around each other, and cut out from the notch 7 of each guide A18. Missing, and each guide A
The string B24 is a double tying device for a string, which can also be tied out of the cut gap A19 of 18 and a second tie as shown in FIG. 10 on the first tie. In the second tying device, when the supplied string B24 is long,
Each of the cords outside of each location 29 gripped by each of the grip fittings 1 and the tube 2 is broken into two, and each of the folded two strings is left as two strings by the action of the second tying device. By tying, a bow can be formed on the first tie as shown in FIG. Next, when the product 30 is to be tied, the product 30 is put into the loop of the guide 6 and the double tying device of the string works as described above, so that the product can be tied as shown in FIG. 6, 10, 11, and 12
The knot is a figure in which the strings are loosely tied for clarity, and is originally tightly tied. Next, in a guide or the like having the same operation as that of the embodiment, a steel material or the like can be formed by groove processing or bending processing instead of a pipe shape.

According to the present invention, it is possible to reduce the labor of the person by making mechanized what has conventionally been done by the hand of the person, and to make uniform knots.
