Abstract

PURPOSE:To reduce manpower by controlling a traverse driving source during a fixed period of time since a reference point mark disposed on the drum flange surface is detected to automatically wind a cable round a drum in line. CONSTITUTION:A drum 1 is rotatably disposed on a truck 5 through a roller 4. The truck 5 is placed on rails 6 mounted along the axis of the drum 1 to move to the right or the left by a traverse driving source 7 mounted on the truck 5. A cable A is drawn out from a fixed guide device 8 and taken up round the drum 1. In this case, a reference point mark 9 is put to the outside surface of one drum flange 2, and a detector 10 for the mark is disposed on the side of the drum on the truck 5. The reference point mark 9 is mounted on a virtual line (m) connecting a virtual point (a) corresponding to a start point for switching the cable A with the center (c) of the drum flange 2. The driving source 7 is controlled during a fixed period of time since the reference point mark 9 is detected.

Description

Detailed Description of the Invention (a) Industrial Application Field This invention is an automatic cable winding device, particularly an automatic cable winding device using a traverse method, in which the cable winding point is automatically detected and the cable winding drum is It is designed to control the traverse of the

(b) Prior Art FIG. 1 shows a state in which cable A is wound around a drum 1 using the traverse method.

The cable A is supplied from a fixed position, passes through the lead separator 3 from the part in contact with the drum flange 2 on the right side, and is gradually wound up toward the drum flange 2' on the left wheel. The cable A goes around the drum 1 for most of the part, and the drum tsuba 2,
2/, so there is no need to traverse the drum 1, but since the part from 1/4 to IA circumference becomes the winding part B, in order to perform aligned winding, it is necessary to traverse the drum 1 by the amount of winding. 1 must be traversed. For this reason, conventionally, workers constantly monitored the deviation of the angle of cable winding, and when they detected deviation in the direction of increasing the angle, they operated the switch button on the traverse motor to cause the drum to traverse a certain amount. Ta.

(c) Problems to be Solved by the Invention As mentioned above, in the past, winding was done manually by detecting the deviation of the angle and driving and stopping the traverse motor. I needed it.

SUMMARY OF THE INVENTION An object of the present invention is to automatically detect the cable winding point and control a traverse drive source such as a traverse motor, thereby reducing manpower.

In order to solve the above-mentioned problems, the present invention provides a reference point mark on an imaginary line connecting an imaginary point on the drum flange surface corresponding to the cable winding start point and the center of the drum flange. A detector for the reference point mark is provided opposite the drum flange, and the traverse drive source is driven for a predetermined period of time when the detector detects the reference point mark.

(E) Embodiment FIGS. 2 and 3 show embodiments of the present invention, in which the drum 1
is rotatably mounted on a truck 5 via rollers 4, the drum 1 is rotated by a drum motor installed on the truck 5, and the truck 5 is placed on a rail 6 provided in the axial direction of the drum 1, A traverse drive source 7 installed on the swan 5 moves the cart 5 to either the left or right.

The cable A is pulled out from the fixed guide device 8 and wound around the drum 1, and the cable A has the above-mentioned winding portion B.

The above structure is the same as the conventional case, but in the case of the present invention, the base point mark 9 is provided on the outer surface of one drum collar 2,
Further, the detector 10 is placed on the trolley 5 on the side of the drum 11.
It is placed above.

The base point mark 9 is provided on the imaginary line m connecting the center C of the drum flange 2 and the imaginary point 3 corresponding to the cable winding start point on the outer surface of the drum flange 2 . Base point mark 9
is, for example, a reflecting mirror, and the detector 10 corresponding thereto is constituted by a mirror reflection type beam switch. In addition, the reference point mark 9 and the detector 10 may be combined in various ways, such as a light emitting element and a light receiving element, a mechanical protrusion and a switch driven by the protrusion.

When the base point mark 9 is detected by the above detector 10,
An electric circuit is provided so that the traverse drive source 7 starts driving. The driving source 7 is stopped after being driven by the width of the winding portion B, and the stopping point is determined by counting the number of rotations of the driving source 7 or by checking the reference point mark 9.
Similarly, if the virtual point corresponds to the end point of the winding, then the center C
This can be done by, for example, providing an end point mark 9' on the virtual line n connecting these points and detecting this with the detector 10.

Note that the above control is not sufficient for the folded portion of the cable A in contact with the Y-ram collar 2.2', so conventional manual control is used. In addition, if the traverse speed is not appropriate in a portion other than the folded portion, overrun or insufficient traverse will occur, so the traverse speed is set to an appropriate speed to ensure aligned winding.

In this case, a microcomputer may be installed and the traverse speed may be controlled according to the calculation results.

Also, when the winding layer changes, the base point mark 9 and the end point mark 91
However, this deviation can be absorbed by making a correction at the beginning of winding each layer.

(→ Effects As mentioned above, this invention detects the reference point mark on the drum flange surface and controls the traverse drive source for a predetermined period of time from that point. Except for automatically aligned winding.

Therefore, it is possible to save labor in cable winding work.
