Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cable winding drum for winding a cable onto a winding drum.

(Prior Art) In a conventional cable winding drum, a groove is provided on the outer circumferential surface of the winding drum so that the cables are wound in an aligned state.

(Problems to be solved by the invention) When winding cables in an aligned manner by providing grooves on the outer peripheral surface of the winding cylinder as in the conventional method, grooves matching the outer diameter of the cables are required. However, there was a problem in that it was not possible to wind cables with different outer diameters, and it lacked versatility.

(Means for Solving the Problems) The present invention addresses the above-mentioned problems, and includes a winding drum with a smooth outer circumferential surface and a tapered roller. and a tapered roller support device that supports the tapered roller near the outer circumferential surface of the take-up cylinder substantially parallel to the rotational center axis of the take-up cylinder so as to be able to approach and separate from the outer circumferential surface of the take-up cylinder; The present invention is characterized in that it includes a tapered roller biasing means for biasing the tapered roller in the direction of the outer circumferential surface of the winding cylinder via the winding cylinder.

An object of the present invention is to provide a cable winding drum that is versatile.

(Function) The cable winding drum of the present invention is constructed as described above, and when the cable is wound onto the winding drum by driving the winding drum in the winding direction, the cable is moved in the direction of the winding drum. The cable is passed between the tapered roller that is energized by the cable and the rotating take-up cylinder, and the tapered roller that is in contact with the cable is rotated.
Push the cable on the smooth outer circumferential surface of the winding cylinder toward the small diameter part of the tapered roller, move it to one side of the outer circumferential surface of the winding cylinder, and wind it up.The cable that follows is moved in the same way on the outer circumferential surface of the winding cylinder. and wind it up in an aligned state.

Further, one end of the rotation center shaft 8 is fixed to the center of the winding drum 2, and a circular plate 10 is fixed to the other end of the rotation center shaft 8. The disc 10, the rotation center shaft 8, and the winding cylinder 2 are flexibly connected to the drive sprocket 8 so as to rotate following the drive sprocket 8. Further, the drive sprocket 8 is driven by a rotary drive device (not shown).

Next, the operation of the cable winding drum shown in FIGS. 1, 2, and 3 will be explained in detail. Winding cylinder 2
When the cable 1 is wound onto the winding cylinder 2 by driving the cable 1 in the winding direction, the winding cylinder 2 is rotated and the tapered roller 6 which urges the cable 1 in the direction of the winding cylinder 2 is rotated. The tapered roller 6 in contact with the cable 1 is rotated, and the cable 1 is
The tapered roller 6 is rolled over the smooth outer peripheral surface of the winding cylinder 2.
The cables 1 are pushed in the direction of the small diameter part, moved to one side of the outer peripheral surface of the winding cylinder 2, and wound up.The subsequent cables 1 are similarly moved on the outer peripheral surface of the winding cylinder 2, and wound in an aligned state.

(Effect of the invention) The cable winding drum of the present invention drives the winding drum in the winding direction as described above, and when winding the cable onto the winding drum, biases the cable in the direction of the winding drum. The cable is passed between the tapered roller that is holding the cable and the rotating take-up cylinder, and the tapered roller that is in contact with the cable is rotated to push the cable onto the smooth outer peripheral surface of the take-up cylinder toward the small diameter part of the taper roller. The cable is moved to one side of the outer circumferential surface of the winding drum and wound up, and subsequent cables are similarly moved on the outer circumferential surface of the winding drum and wound in an aligned state, providing versatility to the cable winding drum. It has a lasting effect.
