Abstract

PURPOSE:To securely and automatically bundle a plurality of wire materials without loosening. CONSTITUTION:An adhesive tape 2 is applied along the outer periphery of the side face of a plurality of wire materials 4 by making use of a leaf spring effect of a couple of right and left pushing up leaf springs 18, 19. Both ends of the adhesive tape 2 are folded in turn by the right and left pushing springs 21, 21 so as to lap over each other hereafter. In this way, the surrounding part of the wires can be completely lapped and hence, the wire materials are not slackened owing to the bundling force.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for binding a plurality of wire rods and automatically binding them using an adhesive tape.

[0002]

2. Description of the Related Art FIGS. 3 and 4 show an example of a conventional apparatus capable of performing neck sealing processing for bags and binding processing for wire rods. In the drawings, 1 has a main body and 2 has an adhesive surface on one side 2a. Adhesive tape 3, groove wheel, 4 wire rod, 5 upper mover, 6 spring, 7 cutter, 8 lower mover, 9 spring, 10 roller, 1a wire rod insertion port.

Next, the operation will be described. When the adhesive tape 2 is previously inserted between the groove wheel 3 and the mover 5 and the wire 4 to be bound is pushed from above the insertion opening 1a, as shown in FIG. The wire 4 is wrapped with the adhesive tape 2 between the groove 3 and the mover 5. Furthermore, FIG. 4 (B)
When the wire rod 4 kicks the mover 8 by pushing the wire rod 4 downward as shown in FIG. 4, the mover 8 turns and the attached cutter 7 cuts the wire rod 4 to a predetermined size. As shown in FIG. It becomes a united form.

[0004]

In the conventional method for binding wire rods as described above, since both ends of the adhesive tape are not wrapped, the binding force is low and play occurs in the bound wire rods.
There was a problem of falling apart.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a method for firmly binding a plurality of wire rods.

[0006]

According to a method of binding a wire rod according to the present invention, a pair of right and left push-up leaf springs are used to attach adhesive tapes along the outer periphery of a plurality of wire rods, and then both ends of the adhesive tape are alternately attached. By affixing it on the upper surface of the adhesive tape, both ends of the adhesive tape can be wrapped and bound, and the binding force is strengthened.

[0007]

In the method of binding a wire rod according to the present invention, since the adhesive tape can be attached along the outer circumference of a plurality of wire rods by using a leaf spring and both ends of the adhesive tape can be wrapped and bound, the binding force becomes strong.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 1, 2 is an adhesive tape having an adhesive surface 2a on one side, 11 is a left roller, 12 is a right roller, 1
3 is a left arm, 14 is a right arm having a cutter 14a at its tip, 15 is a tape feed bar, and 16 is a tape retainer. In FIG. 2, 4 is a wire rod, 17 is a push-up member in which a left push-up leaf spring 18 and a right push-up leaf spring 19 are arranged in an eight shape, and 20 and 21 are a left push spring and a right push spring.

Next, the operation procedure of the automatic wire rod binding method will be described. First, the fixed-size cutting of the adhesive tape 2 will be described with reference to FIG. (A) is the initial state, the adhesive tape 2
Is not gripped between the roller and the arm. As shown in (B), the left roller 11 and the right roller 12 are raised, and the left arm 1
3. The right arm 14 descends, and the adhesive tape is on standby. In (C), the adhesive tape 2 is pulled out to the left by advancing the tape feed bar 15 while the adhesive tape 2 is clamped by the tape retainer 16. In (D), the left roller 11 on the tip end side of the adhesive tape 2 descends and the left arm 13 rises to grip the tip end of the adhesive tape 2. In (E), the tape feed bar 15 retracts, the adhesive tape 2 remains without being retracted while being held by the left roller 11 and the left arm 13, and only the tape feed bar 15 retracts. In (F), the right roller 12 descends and the right arm 14 rises to clamp the right end of the adhesive tape, and at the same time, the adhesive tape 2 is cut by the cutter 14a attached to the right arm 14 to cut the adhesive tape to a predetermined size. Complete the work.

Next, a method of binding the wire 4 will be described with reference to FIG. (A) shows a state in which the adhesive tape 2 is cut into a predetermined size and both ends are gripped by the method of FIG. 1, and the push-up member 17 is installed below the adhesive tape 2. In (B),
The left push-up leaf spring 18 and the right push-up leaf spring 19 are lifted to push up the adhesive tape 2, and both ends of the adhesive tape 2 are removed from the roller and the arm, respectively, and are attached along the left and right side surfaces of the wire 4. The extra adhesive tape on both left and right ends is in a state of standing upright. In (C) and (D), after the push-up member 17 descends, the left pressing spring 20 first advances and the left end of the adhesive tape 2 is attached along the upper surface of the wire 4. In (E), after the left pressing spring 20 moves backward, the right pressing spring 21 moves forward, and the right end of the adhesive tape 2 is stuck along the upper surface of the wire rod 4, that is, the left end of the adhesive tape. Be done. (F) shows a state in which the binding work of the wire 4 is completed.

Embodiment 2. In the above embodiment, if the pitch of the left and right rollers 11 and 12 and the stroke of the tape feed bar 15 are variable, the size of the wire 4 is not limited, and a strong binding is possible.

[0012]

As described above, according to the present invention, the leaf spring effect allows the adhesive tape to be tightly attached to the wire material and the both ends of the adhesive tape can be wrapped so that the binding force is strengthened. It has an excellent effect that the wire rod of is not scattered.
