Description

[Detailed Description of the Invention] [Background and Object of the Invention] The present invention relates to an automatic wire winding method and a winding device, and particularly to a winding bobbin having a tapered body that automatically winds a wire rod. The present invention relates to an automatic wire winding method and a winding device suitable for various cases.

When winding a wire onto a winding bobbin with a normal diameter using a winding device, the traverser of the winding device is moved between both sides (flanges) of the winding bobbin at a constant speed or at a speed proportional to the wire speed. A method of winding the wire while moving the winding position by reciprocating the wire is generally adopted. In addition, when performing such winding, an aquiyum dancer is installed on the winding line of the wire, and the tension fluctuation of the wire is detected by the positional displacement of the aquiyum dancer, and the winding bobbin is adjusted based on this detection signal. The tension of the wire is controlled to an appropriate state by controlling the rotation speed of the wire.

However, when such a winding device is used to wind a wire rod at high speed on a tapered winding bobbin,
Since tension fluctuations occur continuously due to changes in the winding bobbin's body diameter, the rotational speed control of the winding bobbin by the aquiyum dancer cannot be quickly controlled, and as a result, the aquiyum dancer fluctuates violently up and down, causing the roll of the wire to change. Automatic winding of the wire was difficult because of unwinding, breakage, or taper. Conventionally, when winding a wire onto a tapered winding bobbin, a traverser is manually moved while the wire is running at a low speed, or the direction of movement of the wire is controlled manually instead of the traverser. do,
As shown in FIG. 3, the wire rod 11 was wound parallel to the axial direction of the winding bobbin 10. However, when manually winding wire rods, etc., there are problems of inefficiency, such as a heavy human burden and the inability to perform high-speed winding.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic wire winding method that eliminates the drawbacks of the prior art described above and can automatically wind a wire around a tapered winding bobbin.

[Summary of the Invention] The first invention relates to an automatic wire winding method that achieves the above object, and is characterized in that the winding start position is set at the smaller diameter of a winding bobbin having a tapered body. Then, the traverser is moved from this winding start position toward the larger side via a drive mechanism to wind the wire on the winding bobbin, and in the process of winding the wire, the diameter of the body of the winding bobbin changes. Detecting the degree of increase in the winding diameter of the wire based on the positional displacement signal of an aquiyum dancer provided on a wire rod running line, and inverting the traverser to the winding start position based on the positional displacement signal of the aquiyum dancer. When the traverser reaches the winding start position, it issues a limit signal and reverses the traverser again from the winding start position towards the larger body diameter of the winding bobbin. The wire rod is wound by repeating a series of such reciprocating movements.

According to the winding method with such a configuration, the traverser immediately reverses itself when the winding diameter increases beyond a predetermined value in the process of moving from the smaller diameter side of the winding bobbin (winding start position) to the larger body diameter side. When the traverser reaches the winding start position, the winding bobbin reversely moves again to the side with the larger body diameter, and by repeating this process, the wire can be wound while gradually lengthening the movement stroke of the traverser, and the winding bobbin Even if the winding bobbin is tapered, the winding layer that is substantially parallel to the axial direction of the winding bobbin can be formed from the side with the smaller body diameter of the winding bobbin. Therefore, since the wire is wound along these parallel winding layers, the rotational speed of the winding bobbin can be stably controlled by the aquiyum dancer without the aquiyum dancer fluctuating violently. can.

A second invention relates to a winding device that embodies the above-mentioned winding method, and in the winding device that winds a wire rod, a winding bobbin having a tapered body and an axial direction of the winding bobbin are provided. A traverser that moves back and forth via a drive mechanism, an aquiyum dancer that is installed on a wire rod running line and moves up and down in response to changes in the wire winding diameter of the winding bobbin, and a position that detects the positional displacement of this aquiyum dancer. a detecting means; a limit switch that issues a limit signal when the traverser reaches one end of the smaller body diameter of the winding bobbin; A control signal is sent to the drive mechanism of the traverser to cause the traverser to move toward the larger side, and a control signal is sent to the traverser to reversely move the traverser from the current position to the side with the smaller body diameter when the position displacement signal of the aquium dancer is input. The device is characterized by comprising a traverser control means for sending data to the mechanism.

According to such a configuration, the reciprocating movement control of the traverser performed by the automatic winding method described above is performed by a limit switch provided on the smaller diameter side of the winding bobbin (winding start position) and an accumulator dancer. This can be done through the position displacement detection means of the limit switch and the traverser control means that drives and controls the traverser by inputting the limit signal of the limit switch and the position displacement signal of the acquisition dancer, thereby gradually lengthening the reciprocating stroke of the traverser. The wire rod can be wound so as to be substantially parallel to the axial direction of the winding bobbin.

[Example] An example of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a schematic diagram showing an embodiment of an automatic winding system applied to the wire winding method of the present invention. In the figure, 1 is a wire to be wound, and 2 is a winding for winding the wire 1. The winding bobbin 2 has a conductor 3 formed in a tapered shape as shown in FIG. 2, and is configured to rotate via a winding rotation device (not shown). .

Reference numeral 4 denotes a traverser that reciprocates in the axial direction of the winding bobbin 2 via a drive mechanism (not shown).
A limit switch 5 is attached to one end corresponding to the smaller diameter of the body.

6 is a line pulley installed on the wire running line, 7
is an Akyum dancer. When the winding amount of the wire rod 1 to be wound on the winding bobbin 2 changes and tension fluctuation occurs in the wire running line, the Aquium dancer 7 moves upward or downward, and outputs a signal corresponding to this positional change. The winding rotation control means (not shown) accelerates and decelerates the rotational speed of the feed and winding bobbin 2. Furthermore, a proximity switch 8 is installed in the Achilles dancer 7 to detect a change in the position of the Achilles dancer 7. The proximity switch 8 moves the accumulator dancer 7 from a reference position [a position (zero position) in which the rotation of the winding bobbin 2 is not accelerated or decelerated in the rotation control of the winding bobbin 2] to a position direction in which the rotation of the winding bobbin 2 is decelerated. This detects the displacement of the Akyum dancer 7 when the
For example, it is installed at a position where the aquiyum dancer 7 is displaced when the wire rod winding amount of the winding bobbin 2 increases by several meters.

Reference numeral 9 denotes a traverser control means for controlling the drive mechanism of the traverser 4. The traverser control means 9 inputs a linear velocity signal of the wire rod 1 and moves the traverser 4 in the axial direction of the winding bobbin 2 at a speed proportional to this linear velocity signal. It has a speed control function for reciprocating the winding bobbin 2, and also has a control function for inputting a limit signal from the limit switch 5 of the traverser 4 to drive and control the traverser 4 from the smaller to the larger body diameter of the winding bobbin 2. It has a control function that when a position signal of the accumulator dancer 8 detected by the proximity switch 8 is input, a reversal signal is outputted to reversely move the traverser 4 from the current position to the side with the smaller diameter of the winding bobbin 2.

Next, a specific example of a method for automatically winding a wire using such an automatic winding system will be described.

When winding the wire 1, first place one end of the winding bobbin 2 with the smaller body diameter at the winding start position S.
Attach one end of the wire rod 1 to the winding start position S,
When the winding bobbin 2 is rotated, the traverser 4 is moved from the winding start position S to the side of the winding bobbin 2 with a larger diameter via a drive mechanism. When the traverser 4 is moved, the wire 1 is moved along with the winding bobbin 2.
The winding diameter gradually increases in accordance with changes in the body diameter of the winding bobbin 2.
Then, due to the increase in the winding diameter of the wire rod 1, the wire rod 1
The winding speed of the wire rod 1 increases, and the tension of the wire rod 1 on the wire rod travel line increases. akyum dancer 6
Due to this tension variation, the position of the winding bobbin 2 is displaced in a direction (for example, upward) in which the rotational speed of the winding bobbin 2 is controlled to be decelerated.

When the proximity switch 8 detects such a positional displacement of the aquium dancer 7 and activates the traverser control means 9, the traverser 4
The drive mechanism is reversely controlled, and the traverser 4 is reversely moved to the winding start position S side.

By this first movement stroke of the traverser 4, the layer 1a having the narrowest width of the winding layer is first formed on the side of the winding bobbin 2 having a smaller body diameter. In addition, due to the reverse movement of the traverser 4 toward the winding start position S side, the second
A winding layer 1b is formed. When the traverser 4 reaches the winding start position S, the limit switch 5
The traverser 4
, the traverser 4 is moved again to the larger diameter side of the winding bobbin 2, and the wire rod 1 is moved.
wind it up. During the moving process of the traverser 4, a third winding layer 1c is formed, and this winding layer 1c
When the wire rod 1 reaches the tapered surface of the winding bobbin 2 during the formation process and the winding diameter increases due to a change (increase) in the body diameter of the winding bobbin 2, the position of the accumulator dancer 7 is again displaced. Then, as described above, when the positional displacement of the accumulator dancer 7 is detected by the proximity switch 8 and the traverser 4 is reversely moved to the winding start position S side via the traverser control means 9, the winding layer 1d is is formed, and thereafter, the wire rod is wound by repeatedly performing such a series of winding operations.

Through such reciprocating drive control, the traverser 4 moves while gradually lengthening the reciprocating stroke as shown by arrow A in FIG. 2, thereby moving the winding position of the wire rod. It is possible to form winding layers 1a, 1b, 1c, . . . that are substantially parallel to each other.

Therefore, according to this embodiment, since the wire can be wound while forming a winding layer that is substantially parallel to the axial direction of the winding bobbin 2, the accumulation dancer 7 does not fluctuate violently and the Youmu dancer 7
The rotational speed of the winding bobbin 2 can be controlled in a stable manner, and as a result, the wire rod 1 can be prevented from unrolling, wire breakage, or unwinding of the wire rod due to the taper, and the wire rod can be wound around the tapered winding bobbin. Can be automatically wound.

[Effects of the Invention] As described above, according to the present invention, the wire rod can be automatically wound around the tapered winding bobbin in a stable state, so the work efficiency of the winding work can be greatly improved. In addition, the human burden can be significantly reduced.
