Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping device for winding a tape around a short cable.

[0002]

2. Description of the Related Art A conventional taping device for winding a tape around a short cable generally winds the tape by rotating the tape around the cable while feeding the cable, and there are horizontal and vertical devices.

FIG. 4 is a schematic view of a conventional short cable taping apparatus. The outline of a horizontal general device is shown. The short cable 21 around which the tape 22 is wound passes through the center of the tape rotating unit 23 and the slit pipe 24 and is sent from right to left in FIG. At the same time, the tape rotating unit 23 containing the tape 22 rotates around the cable 21. The tape 22 is wound around the cable 21 via the slit pipe 24 so that the tape 22 is wound at a constant pitch and in an orderly manner. The cable sent and wound with the tape is taken by a cable take-up device.

[0004]

The conventional short taping device for a short cable has the following problems.

[0005] (1) To send out a cable, a cable take-up device is required. Therefore, (a) a lead wire is required at the end of the cable.

(B) If a lead wire is not used, a wasted cable length increases.

(C) The entire taping device becomes large, the installation space is large, and the price is high.

(2) The apparatus becomes complicated due to the presence of the tape rotating section. When the tape runs out, the apparatus must be stopped, and the setup time for tape replacement is long.

(3) When a lead wire is used, twisting occurs at a connection portion with the cable, and taping pitch disturbance occurs.

Accordingly, an object of the present invention is to solve the above-mentioned disadvantages of the prior art, and (1) the installation space is small and inexpensive; (2) the wasted cable length is short; and (3) the tape exchange setup. An object of the present invention is to provide a taping device for a short cable in which time is short and (4) taping pitch is not disturbed.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a cable rotating device that rotates while holding both ends of a cable, and a tape feeding device that feeds a tape to the cable and moves the tape in the longitudinal direction. Device.

The cable rotating device includes a fixed chuck, a tension chuck, a scroll chuck, a chuck rotation drive, a chuck rotation shaft, and a chuck rotation motor.

The tension side chuck section, scroll chuck and chuck rotation drive section are configured to be movable left and right.

[0014] The chuck rotation driving section is constituted by a spline or a key.

The above-mentioned tape feeding device comprises a tape feeding section, a traversing drive section, and a traversing motor.

The tape feeding section includes a tape holder,
It consisted of a tape guide and a slit pipe.

The tape holder, the tape guide and the slit pipe are installed on the same base so that they can be traversed by a linear guide.

The chuck rotation motor and the traversing motor are variable speed motors whose rotation speed can be set arbitrarily.

[0019]

FIG. 1 shows an embodiment of a short cable taping device according to the present invention.
(A) is a plan view and (b) is a front view. The apparatus includes a cable rotating device that rotates while holding both ends of a cable, and a tape feeding device that sends a tape to the cable and is movable in a longitudinal direction. The cable rotation device includes a fixed-side chuck section 3, a tension-side chuck section 4, a scroll chuck 5, a chuck rotation drive section 6, a chuck rotation motor 7, and a chuck rotation shaft 8. The tape feeding device includes a tape feeding unit 10, a traversing drive unit 15, and a traversing motor 16.

The short cable 1 has a fixed side chuck 3
And the scroll chuck 5, and the tension side chuck portion 4 and the scroll chuck 5. Since the rotation of the chuck rotation motor 7 is transmitted to the fixed-side chuck portion 3 and the tension-side chuck portion 4 via the chuck rotation shaft 8 and the chuck rotation drive unit 6, the cable 1 rotates. In this case, since the shaft is driven, the rotation speeds of the fixed chuck 3 and the tension chuck 4 are the same.

Since the tape 2 cannot be wound neatly unless tension is applied to the cable 1, the tension side chuck portion 4, the scroll chuck 5, and the chuck rotation drive portion 6 are configured to be slidable left and right. The chuck rotation drive unit 6 at that portion uses a spline or a key, and can be driven even when slid.

FIGS. 2A and 2B are enlarged views of the cable rotating device of FIG. 1, wherein FIG. 2A is a front view and FIG. 2B is a side view. The axis of the fixed-side chuck portion 3 and the scroll chuck 5 is constituted by a chuck portion hollow shaft 9, and the cable 1 can pass through the inside of the chuck portion hollow shaft 9. The position of the cable 1 is adjusted by the scroll chuck 5 so that the cable 1 is positioned exactly at the center of the chuck hollow shaft 9.

As described above, the rotation of the chuck rotation shaft 8 is transmitted to the scroll chuck 5 via the chuck rotation drive unit 6, and the cable 1 is rotated because the scroll chuck 5 and the cable 1 are fixed. It has a structure that can be used.

FIGS. 3A and 3B are enlarged views of the tape feeding device of FIG. 1, wherein FIG. 3A is a plan view and FIG. 3B is a side view. The tape 2 is held by a tape holder 11, sent out at a constant tension, and has a structure that can be adjusted to an appropriate angle by a tape guide 12. At the winding point of the tape, a slit pipe 13 is provided so that the cable 1 can be prevented from swaying and can be wound neatly at a constant pitch. The same effect can be obtained by pressing with a die instead of the slit pipe.

The tape holder 11 and the tape guide 12
And the slit pipe 13 are installed on the same base,
The linear guide 14 is configured to smoothly move in the lateral direction. The lateral movement is performed by a traversing drive unit 15 and a traversing motor 16.

Note that the chuck rotation motor 7 and the traversing motor 16 each use a variable speed motor whose rotation speed can be arbitrarily set. Therefore, the rotation speed of the cable 1 is set to N
Assuming that t and the tape traversing speed are Vt, the taping pitch P is given by P = Vt / Nt, where Nt and Vt can be set arbitrarily, so that the taping pitch can also be set arbitrarily according to the above equation.

[0027]

According to the present invention, there is provided a short cable taping device comprising: a cable rotating device for holding and rotating a cable;
The following effects are exhibited by providing the tape feeding device capable of feeding the tape to the cable and moving in the longitudinal direction.

(1) No cable take-up device is required,
Since only the cable rotates, the device is small and inexpensive, and the installation space is small.

(2) The wasted cable length is short.

(3) The setup time for tape exchange is short.

(4) There is no disturbance in taping pitch.
