2. Description of the Related Art Conventionally, there has been known a traveling drive device and a winding device for winding a wire rope around a winding drum and winding and unwinding the rope at the same time by rotating the winding drum. If there is no groove for the rope, the ropes may interfere with each other during winding and unwinding and the ropes may be twisted or the winding may become irregular and the ropes may be easily damaged or stop functioning. Was. In addition, there is a practical drive 5-52854 (bending feed device) for the traveling drive device that winds the rope in the middle of the rope while keeping the rope stationary and unwinds it at the same time, winding the fixed wire around the capstan and moving it. However, even with multiple wires, the possibility of slippage could not be completely eliminated. Further, JP-A-5-12589 (synchronous lifting device) has a structure in which when winding a wire in a winding cylinder, the wire is supported movably in the axial direction in synchronization with the rotation of the winding cylinder, but is wound in parallel only in one direction, In the case of moving in the opposite direction, there were problems such as no action force other than gravity acting and compactness. Next, the present inventor applied for a friction winding type drive device of Japanese Patent Application No. 2001-254044. With this method, the random winding of the rope was solved, but there were still problems left to solve the damage of the rope. The present invention seeks to remedy the above problems and provide further applications.

[0003]

SUMMARY OF THE INVENTION The problems to be solved by the present invention are to solve the above-mentioned problems, to prevent the ropes from being wound up and fed out from interfering with each other to prevent the ropes from being damaged, and in any direction. It is to provide a drive device that is safer, simpler, quieter, and has new functions.

The structure of the present invention, which has solved the above-mentioned problems, is a winding cylinder for winding two ropes stretched along a passage, and having a shaft center perpendicular to the passage. Two tensioned ropes are fixed to one end side and the other end side of the winding cylinder in the axial direction, respectively, and are wound around the winding cylinder in opposite directions so as not to overlap toward the center of the winding cylinder. In a device in which the other end of each of the ropes is connected to both ends of the passage so that the winding drum moves axially every rope diameter or more per rotation of the winding drum in synchronization with the rotation of the winding drum, The length of the rope from one end to one end of the winding drum and the length of the other rope from the other end of the passage to the other end of the winding drum are substantially the same, and one or more ropes are provided near the winding drum. There is a rotatable intermediate wheel, and each of the ropes from one end and the other end of the passage is After being wound within at least one lap, it is wound on the winding cylinder, and further, two or more guide rails along the passage and two or more series of the rails that move in parallel or face each other along the guide rail. In a traveling drive device that includes a winding drum type driving device and is guided by the guide rail and has a transportation facility such as a chair or a container attached thereto, if one winding drum is rotated, a toothed wheel or a screw By interlocking the rotation and axial movement of the other winding cylinder, in addition, the diameter of the winding cylinder is tapered from one end to the other end of the winding cylinder, and a displacement measuring machine is provided at one end of the passage. Then, one end side of the rope was fixed and controlled by the information from the displacement measuring machine.
