Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insulating tube insertion device for inserting a soft insulating tube of a predetermined length into a part of a rectangular electric wire.

In general, fitting a cylindrical soft material insulating tube with a built-in soft material such as non-woven fabric and reinforced with insulating tape to the outer periphery of a rectangular electric wire with a rectangular cross section is a matter of This was extremely difficult because the margin of error was only a few percent. One method is to insert an insulating tube into a two-piece guide that has the same shape as the rectangular cross-sectional flat wire.

Attempts were made to insert a rectangular electric wire into this continuous tube, but the structure became complicated and it was difficult to put it to practical use.

The present invention was made in view of the above-mentioned situation, and an object of the present invention is to provide an insulating tube insertion device that can smoothly and efficiently insert an insulating tube of a predetermined length into a part of a rectangular electric wire. .

The insulating tube insertion device of the present invention is made by inserting a soft insulating tube of a predetermined length into a part of a rectangular electric wire, and includes means for fixing the rectangular electric wire on a frame, and an insertion end of the rectangular electric wire that is inserted at an angle. Hold and fix the insulating tube that has been cut and has its tip side facing downward and the end of the rectangular electric wire is placed on one side; and the insulating tube is held and fixed in a predetermined position with the ends of the rectangular electric wire and the insulating tube overlapped. an inclined plate attached so as to be tiltable at an angle of , and the inclined plate is moved in a direction to further deepen the fitting with the end portions of the rectangular electric wire and the insulating tube fitted together by the angle tilting of the inclined plate; and means for moving the inclined plate in a direction to further deepen the fit after returning the inclined plate to the position before the tilting. That is, the end of the insulating tube whose end has been cut diagonally is positioned downward, and the end of the rectangular electric wire is placed thereon, and the insulating tube is tilted through an inclined plate, thereby separating the ends of the rectangular electric wire and the insulating tube. The parts are fitted together, the fitting is further deepened in this state, and then the fitting is deepened further with the inclined plate returned to the state before tilting and insertion is made.

An embodiment of the insulating tube insertion device of the present invention will be described below with reference to FIGS. 1 to 8. Figure 1 is a plan view of the insulating tube insertion device, Figure 2 (2) is a front view of Figure 1, Figure 3 is a 7-inch lower chart of the operation of the device in Figure 1, Figure 4 (A),
(B) and (C) are respectively block diagrams of the circuits of each part of the device in FIG. 1, FIG. 5 is a detailed view of section A in FIG. 1, FIG. 6 is a sectional view of FIG. FIG. 8 is an explanatory diagram of insertion of an insulating tube.

In Figures 1 and 2, 1 is the base, and base 1
In this case, a squerier driven by a pulse motor 4 fixed to the frame 7 is screwed together and guided by a sliding guide 5. It is moved to a predetermined position and stopped by a pulse. Further, a tilted plate 9 is provided on the base 1 so as to be rotatable about a guide shaft 8. The tilted angle of the tilted plate 9 is maintained by a tilted cylinder 10, and the tilted angle is detected by a tilted position sensor 11. , is performed by the return position sensor 12.

A pair of clamp fittings 13 are mounted on the inclined plate 9 to clamp the soft insulating tube 24 cut to a predetermined length to be coated.
．． 14 are connected to the sensor 1 through linear guides 15 and 16, respectively.
7, a clamp cylinder 19 with a sensor 18, and a clamp cylinder 20 connected in a planar position. Further, a wire positioning cylinder 22 for positioning the rectangular electric wire m21 is mounted on the base 1, and a wire positioning lamp cylinder 23 for preventing the rectangular electric wire 21 from moving when inserting the insulating tube 24 is mounted on the frame 7. It is provided.

FIG. 3 shows a flowchart: ``Operating condition setting'' after ``Operating preparation'' is a control block shown in FIG. This is a block for setting the value of s, @82lS3 of the movement amount setting value preset counter 25. However, the control circuits for the pulse motor 4, the tilt cylinder 9, and the clamp cylinders 19 and 20 are each simple circuits as shown in FIG.

Next, the operation will be explained using the flowchart of FIG. 3 with reference to FIGS. 1, 2, and 4. Clamp cylinder 1
3. An insulating tube 24 with the opposite end of the flat electric wire 21 cut diagonally and the tip facing the lower side is supplied between 3.14 and clamped by the clamp cylinder 19.20, and the flat electric wire is attached to the upper surface of the lower end of the insulating tube 24. Attach it as shown in FIGS. 5 and 6 so that the end of 21 is placed on it. Next, the tilt plate 9 is tilted around the guide shaft 8 by the tilt cylinder 10, and the tilt angle is detected by the tilt position sensor 11.
These controls are performed by the circuit shown in the block diagram of FIG. 4(b). Since the insulating tube 24 is tilted by the above operation, the oblique insulating tube 24 comes to cover the upper side of the terminal of the rectangular electric wire 21. That is, the end of the insulating tube 24 is inserted into the terminal of the rectangular electric wire 21.

While maintaining the above state, the base 1 is moved by a set movement amount S1 in the insertion direction (direction of deepening the fitting) by the pulse motor 4. As a result, completely insulated tube 2
4 is inserted into the end of the rectangular electric wire 21, the next step is to tilt the tube back, that is, move the tilt plate 9 to the tilt cylinder 10.
Even if the sensor 12 is returned to its pre-tilt position, the so-called flat position, the insulating tube 24 is still attached to the rectangular electric wire 21.
I can't get away from it. After this tube tilt return process, the clamp fittings 13 and 14 are unclamped, and the base 1 is moved by a set movement amount S in the insertion direction by the pulse motor 4 while checking with the sensor 18. As a result, the seventh
Insulating tube 2 inserted into rectangular electric wire 21 as shown in the figure
4, and clamp the insulating tube 24 again between the clamp fittings 13 and 14. Thereafter, the pacer 1 is moved by the pulse motor 4 by a set movement amount S3 in the insertion direction. That is, the insulating tube 24 is inserted into a predetermined position and formed as shown in FIG. 8, and the insertion operation is completed, and these controls are performed according to the block diagram of () 1 in FIG. 4.

As described above, the insulating tube insertion device of this embodiment has a simple structure, and can smoothly and efficiently insert a soft insulating tube of a predetermined length into a rectangular cross-section flat electric wire using the flat electric wire as a guide, and can be automated. be.

As described above, the insulating tube insertion device of the present invention has the effect of smoothly and efficiently inserting an insulating tube of a predetermined length into two parts of a rectangular electric wire.
