Abstract

PURPOSE:To facilitate the operation of binding cables together with binding material and use the binding material independently of the contour and outside diameter dimension of the cables to be bound together. CONSTITUTION:The cables 5 to be bound together are retained in a cable retaining hole between a main body part 1 and an opening/closing reverse head part 4, binding material 9 is fed from a reel 9a by feed rollers 10 and is guided and reversed by a reversing groove 4a provided in the inner surface of a cable retaining groove on the side of the reverse head part forming the cable retaining hole. The reversed binding material is retained by a retaining part 12 and, by a fusing part 6, the binding material between the cable retaining hole and the retaining part 12 is forced against the binding material 9 between the cable retaining hole and the feed rollers to attain the fusion therebetween.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable bundling device for wrapping a plurality of wires such as electric wires around a wire to be bound with a tape-shaped or string-shaped tying material and further tightening to tie the wire to be bound. Regarding vessels.

2. Description of the Related Art FIG. 6 shows a wire fastener (trademark) 50 which is a conventionally used binding material. In order to bind the bundled wires 5 with this wire fastener 50 as shown in FIG. 7, hold one end 53 of the wire fastener 50 with one hand,
Holding the other end 51 with another hand and moving it as shown by an arrow 54, a loop is formed so that the wire 5 to be bound enters, and the end 51 is inserted into a hole 52 provided in the end 53 and temporarily fixed. Hole 52
When the end 51 side of the wire fastener 50 is inserted into the wire fastener 50 for a sufficient length, the leaf spring provided in the hole 52 engages with the unevenness provided on the surface of the wire fastener 50, and the end 51 of the wire fastener 50 The structure is such that the side does not return in the direction of coming out of the hole 52.

In the conventional cable tying device, the wire fastener 50 in the state shown in FIG.
The end 53 was pushed in the opposite direction to tighten the bundled wire 5, and then the surplus portion of the wire fastener 50 on the end 51 side was cut off.

[0004]

In the above-mentioned conventional cable tying device, the wire fastener is manually wound around the wire to be bound in advance and temporarily fixed, and then the wire fastener is tightened using the cable tying device to remove the excess portion. The work up to the temporary fixing for cutting is largely dependent on the manual work of a person, and a large number of man-hours are required to perform a large number of bindings. Also, the wire fastener used as a binding material has a different length depending on the outer diameter size and shape of the wire to be bound, so it is necessary to use different types depending on the wire to be bound. There was a problem such as the need to manage.

When it becomes necessary to bind the inner portion of an electric device such as a computer or a switch, both hands must be put in the inner portion of the device to handle the wire fastener, and the work must be performed. There was a risk that the hands would be injured by the internal edges of the device. In addition, if the working posture becomes bad, it becomes difficult to handle the wire fastener, which may cause binding failure.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is an external perspective view of an embodiment of the present invention. As shown in FIG. 2, the reversing head part 4 is connected to the main body part 1 by a hinge 8 so as to be openable and closable, and the main body part 1 and the reversing head part 4 are opened and closed so as to form a bound wire holding hole 15 when closed. Bundled wire holding grooves 15a and 15b are provided on the surface. 3 is a plan view of the main body portion 1, FIG. 4 is a perspective view showing the relationship between the welding portion 6, the fixing portion 7, the wire 5 to be bound, and the binding material 9a. FIG. It is a block diagram shown.

In order to perform the binding according to this embodiment, first, the reversing head portion 4 is opened and the wire 5 to be bound is held in the wire holding groove 15 to be bound.
After being placed in a, the reversing head unit 4 is closed and the bundled wire 5 is taken into the bundled wire holding hole 15. The binding material 9 is fed from the reel 9 and is fed out until the leading end is nipped by the pair of feeding rollers 10.

When the switch 2 is pressed, the following operations are continuously performed by the control of an electric circuit (not shown). The delivery roller 10 is driven to move the binding material 9 into the binding material through hole 1b (see FIG. 4).
(Refer to FIG. 4), passing in front of the fixing portion 7 and holding the bundled wire holding groove 15
The direction is reversed by being guided by the reversing groove 4a provided on the inner surface of b, and passes through in front of the welding portion 6 and between the pair of holding portions 12, and reaches to the front of the sensor 11. When the front end of the binding material 9 is optically detected by the sensor 11, for example, the feeding roller 10 is stopped and the pair of holding portions 12 cause the binding material 9 to bind.
Is driven so as to sandwich. Next, the welding portion 6 moves toward the fixing portion 7 while pushing the binding material 9 on the welding portion 6 side.
At this time, the binding material 9 that passes through the outer periphery of the wire to be bound 5 is placed in the reverse groove 4
It comes off from a and the wire to be bound 5 is wound and tightened. In this state, the two binding materials 9 on the welding portion 6 side and the fixing portion 7 side are sandwiched between the welding portion 6 and the fixing portion 7 to be welded by ultrasonic vibration, and finally a cutting portion provided in contact with the lower surface of the welding portion 6 6
a is further advanced to the fixed portion 7 side, and the binding material 9 around which the wire 5 to be bound is wound is separated from the reel 9a side by a blade formed at the tip of the cutting portion 6a.

A cord 3 for supplying electric power to the welding portion 6 and the like is connected to the main body portion 1.

In this embodiment, the tip of the binding material 9 is attached to the sensor 1.
1, the feeding roller 10 is stopped, but the binding material 9 having a length from the cut portion by the cutting portion 6a to the lower end of the holding portion 12 is fed for each binding operation.
You may make it send out by 0.

The present invention can be implemented without the inversion groove 4a. However, in this case, a sufficient gap is required between the bound wire 5 and the inner surface of the bound wire holding groove 15b so that the binding material 9 can pass therethrough.

[0016]

As described above, according to the present invention, after the wire to be bound is housed between the main body portion and the reversing head portion which opens and closes,
Since the binding material is automatically fed out and wrapped around the wire to be bound, the binding work can be done easily without the need for temporary fixing by hand like the cable binding device using the conventional wire fastener.

Further, since the binding material fed out from the reel-shaped binding material is cut and used, it is not affected by the outer diameter dimension of the wire to be bound, and it is not necessary to use different length types like wire fasteners. Can be done.

Furthermore, the binding of the wires to be bound such as the wiring provided in the inner part of the electric device is performed by the reversing head section.
Since a plurality of bundled wires can be gathered and the work can be performed with one hand, the work becomes easy.
