Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for detecting abnormal operation of a traverser used when winding a filament such as an electric wire onto a drum.

To wind a long wire such as an electric wire onto a drum, the winding position is sequentially reciprocated from one end of the drum to the other so that the wire is evenly wound around the drum. A traverser is used to move it. Various mechanisms have been proposed and put into practical use as mechanisms for reciprocating the winding position of the traverser, but the main advantage is that the traverser can be moved around the screw shaft due to the advantage that the width of movement and the pitch of movement can be arbitrarily selected. The traverser is supported and moved reciprocally by reversibly rotating the screw shaft, but there are cases where the traverser overruns due to wear or damage to parts, or becomes unable to move due to slipping or sticking. Such problems are likely to occur, and there is a risk that the filament may be wound unevenly or cut.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a detection method capable of eliminating the drawbacks of the prior art as described above, monitoring the operation of a traverser, and preventing the occurrence of failures due to abnormal operation.

The gist of the present invention is to provide detection means at both end positions of the reciprocating movement of the traverser, and to detect whether the traverser moves between the detection means within a predetermined time. An embodiment will be described with reference to the drawings.

First, a description will be given of the detection device used in the embodiments of the invention.The detection device is a device that reciprocates parallel to the winding drum 2 of a drum 1 for winding a long filament such as an electric wire and a distance corresponding to the width of the drum 1. established,
Limit switches 4 are installed at both ends of the movement of the traverser 3 for reciprocating the winding position of the filament on the drum 1 to detect the arrival of the traverser 3.
a and 4b are provided, respectively.

When the limit switches 4a and 4b as detection means are operated by the traverser 3,
As will be described later, the timers 5 are activated. The timer 5 is preferably connected to means (none of which are shown) for notifying the occurrence of an abnormality so as to stop the line, mainly the winding operation, when an abnormality occurs in the operation of the traverser 3, which will be described later. There is.

Next, the abnormality detection method of the present invention performed using the detection device configured as described above will be explained. The time required to travel between both ends of the movement of the timer 5
After setting in advance, the winding operation of the filament is started.

For example, when the traverser 3 is operated to move from the moving end on the side where one limit switch 4a is provided to the moving end on the other limit switch 4b side, the traverser 3 first moves from the moving end on the side where one limit switch 4a is provided.
is activated to start timer 5. timer 5
When the traverser 3 is moved to the opposing moving end within the set time, the limit switch 4b is activated, the timer 5 stops counting, and is activated to start counting from the initial state, and then the traverser 3 is reversed. When the user moves and operates the limit switch 4a, the timer 5 is similarly displayed and restarted, and this operation continues until the wire winding operation is completed. The fact that the limit switches 4a, 4b are operated alternately within the set time means that the traverser 3 moves in a predetermined manner and is normally operating the winding operation.

On the other hand, if an abnormal operation occurs, such as when the movement of the traverser 3 overruns, slips, or stops due to sticking, etc., the traverser 3 switches each limit switch 4a.
The time required to operate 4b and 4b will be longer than the set time of the timer 5, but in such a case, the line will be stopped when the timer 5 finishes counting, and the drum 1 will be evenly distributed to the winding drum 2. It is possible to reliably and early prevent problems such as obstruction of uniform winding of the wire and breakage of the filament.

Similarly, even if for some reason the width of movement of the traverser becomes shorter than the predetermined movement interval, or the movement of the traverser is biased, the timer will stop counting if only one limit switch is activated. and does not perform a restart, therefore stopping the line at the end of the timer's timing.

As described above, according to the present invention, the operating state of the traverser is determined by measuring the time required for the traverser to move using the detection means provided at both ends of the traverser's movement, and comparing it with the time set in a preset timer. By constantly monitoring the line and stopping the line when a difference occurs between the time required for moving the traverser and the time set on the timer, it is possible to reliably prevent problems in the winding operation at the beginning.
