[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide mechanism for a cable of a self-propelled truck moving while pulling the cable along a rail laid three-dimensionally.

[0002]

2. Description of the Related Art FIG. 5 is an overall view of a self-propelled trolley moving along a three-dimensionally laid rail. A rail 2 is laid three-dimensionally, and a self-propelled trolley 4 is movable along the rail 2. It has a running device 12, and a cable 7 whose tip is attached to the self-propelled device 12 is guided in a guide roller unit 1 provided on the side surface of the rail 2.

FIG. 6 shows an example of a conventional cable guide mechanism. The required number of guide roller units 13 are fixed to the rail 2.
The cables 4 and 15 are arranged so that the cable 7 does not fall off according to the state of the rail 2 (so that the cable 7 is pressed against the guide roller 14 or 15 by the tension of the cable 7). The cable 7 passes beside the guide rollers 14 and 15, and is held by a cable holding bracket 16 of an appropriate shape fixed to the carriage 4 to prevent interference with the guide rollers 14 and 15.

FIGS. 7 and 8 (a), 8 (b) and 8 (c) show another example of a conventional cable guide mechanism, in which a guide roller 17 is also required above the cable 7. FIG. In this case, since the guide roller 17 and the cable holding bracket 16 interfere with each other, the guide roller 17 is supported by the holding bracket 19 via the spring 20 on the bracket 18 fixed to the rail 2. The structure is such that the roller unit 13 can move up and down.

FIGS. 8A and 8B show a cable holding bracket 16.
A guide plate 21 as shown in FIG. 8C is provided, and the cable tip 22 reaches the guide roller 17 (FIG. 8).
(a)), and further, the guide roller 17 is moved to the guide plate 21.
After the cable tip 22 has passed, the guide roller 17 is pushed by the spring 20 to return to the original position (FIG. 8C), and the cable 7 is moved to the guide roller unit 13 (FIG. 8C). Will be retained.

[0006]

As described above, in the conventional cable guide mechanism, since a floating device using a spring is provided on a guide roller that interferes with the end of the cable, the structure is complicated and causes a failure. And the cost was high.

[0007]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. In a self-propelled bogie that runs while pulling a cable along a three-dimensionally arranged rail, the self-propelled bogie runs along the side of the rail. A required number of guide roller units each with a cable guide fitting are provided, and the guide roller unit is rotatably mounted on a fixed shaft on a self-propelled carriage. The cable penetrates a U-shaped pipe fitting guided by the cable guide fitting, and the center of the cable is a guide roller. It is a cable guide mechanism for a self-propelled bogie arranged at the center.

[0008]

Since the cable guide mechanism according to the present invention is configured as described above, the guide roller side needs only a simple cable guide fitting, and the self-propelled trolley side has a swinging U-shaped cable holding fitting. In addition, a guide roller that interferes with the traveling of the self-propelled carriage can be avoided. Since the swing mechanism of the swing U-tube type cable holding bracket naturally returns to the vicinity of the neutral position due to the tension of the cable, no special resetting device is required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. 1 is a plan view, FIG. 2 is a side view, FIG. 3 is a view taken along the line XX in FIG. 1, and FIG. 4 is a view taken in the direction in which the guide roller of FIG. In FIG. 1, a required number of guide roller units 1 are fixed along the side surface of the rail 2, and a cable guide fitting 3 is a steel wire formed into a mountain shape, and both ends are fixed to the side surface of the rail 2.

In FIG. 2, a self-propelled carriage 4 is provided with a swinging U-shaped pipe type cable holding bracket 5 (hereinafter abbreviated as a U-shaped pipe) around a rotating shaft 6 fixed to the self-propelled carriage 4. Attached so that you can swing. A cable 7 for driving and controlling the self-propelled carriage 4 penetrates through the U-shaped tube 5, and the self-propelled carriage 4 moves by pulling the cable 7. The self-propelled trolley 4 is self-propelled as shown in FIG. At this time, the self-propelled carriage 4 and the cable drum 8 are controlled so that an appropriate tension always acts on the cable 7.

In FIG. 1 and FIG. 2, the center line of the cable 7 is arranged so that its axis coincides with the center of the roller groove of the rollers 9 and 10 whose axes are orthogonal to each other. Mounted to match center level.

The self-propelled carriage 4, ie, the U-shaped tube 5 moves in the direction of the arrow, and when the U-shaped tube 5 comes into contact with the cable guide fitting 3, the tip of the U-shaped tube 5 moves along the cable guide fitting 3, The cable 7 is also bent as shown by the dotted line. After passing through the cable guide fitting 3, the cable 7 returns to the center of the roller grooves of the rollers 9 and 10 by the tension of the cable 7 again. Thus, even when the self-propelled carriage 4 moves, the cable 7 is connected to the rollers 9 and 1 while the guide roller unit 1 is avoided by the U-shaped tube 5.
0 can guide you. In the U-shaped tube 5, the cable 7 is conducting, and the tension acting on the cable 7 provides a restoring force to the neutral point. It substantially coincides with the traveling direction of the traveling vehicle 4.

FIG. 3 shows the arrangement of the rollers 9 and 10 in the case of FIG. 1. In this case, the arrangement is for straight traveling, turning right, and descending. FIG. 4 shows an example of the arrangement opposite to that of FIG. A roller 11 is provided on the opposite side of the roller 10 described above.

By arranging the rollers in this manner, the cable 7 is constantly pressed against the roller by the tension acting on the cable 7, so that the cable 7 is guided without falling off the roller.

[0015]

[Effects of the Invention] As described above, the cable guide mechanism of the present invention has a simpler structure, less failures, and
Production costs are also low. Maintenance is also easy.
