Description

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

When winding a wire onto a normal cylindrical winding bobbin 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 winding speed. Generally, a method of rewinding the material by reciprocating it is employed. 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 wire at high speed on a tapered winding bobbin, tension fluctuations occur continuously due to changes in the body diameter of the winding bobbin. The rotational speed control of the winding bobbin was not able to respond quickly, and as a result, the accumulator dancer fluctuated violently up and down, causing the wire rod to come off the roll, and winding to break due to breakage or taper, making it difficult to automatically wind the wire. . Conventionally, when winding a wire onto a tapered winding bobbin, a traverser is manually moved while the wire is fed at a low speed, or the direction of movement of the wire is controlled manually instead of the traverser. Then, as shown in FIG. 3, the wire rod 12 was wound so as to be parallel to the axial direction of the winding bobbin 11. 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-mentioned object. A member to be detected is provided facing in the axial direction of the take-up bobbin, and a detector for detecting the member to be detected is installed on the traverser side of the take-up device, and the traverser is placed in the direction of the take-up bobbin from the side with the smaller body diameter. The winding bobbin is moved to the larger side via a drive function, and winding of the wire is started from the side with the smaller body diameter of the winding bobbin. Detecting the provided member to be detected, and using the detection signal of the detector to reversely move the traverser to the winding start position of the wire rod to wind the wire rod, and when the traverser reaches the winding start position of the wire rod, A limit signal is issued to reversely move the traverser again toward the larger body diameter of the winding bobbin, and this reverse movement moves the traverser to the winding position where the wire on the winding bobbin is not yet wound. When the detected member is exposed at the winding position, the detected member is detected through the detector of the traverser, and the traverser is reversely moved to the winding start position of the wire;
By repeating such reciprocating movement of the traverser, the wire rod is wound onto the winding bobbin.

According to the winding method with such a configuration, at the beginning of winding the wire, the moving traverser reverses itself in a short stroke, and thereafter, in the stroke in which the traverser moves from the smaller to the larger body diameter of the winding bobbin. Since the reversal control is performed when the wire reaches the winding position where it has not yet been wound, by repeating this reversal control, the winding bobbin that can wind the wire while gradually lengthening the travel stroke of the traverser becomes tapered. Even if the winding layer is substantially parallel to the axial direction of the winding bobbin, the winding layer can be formed to be gradually longer from the side with the smaller body diameter of the winding bobbin.

Therefore, since the wire is wound along such a directional winding layer, 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, a member to be detected is axially oriented on the outer circumferential surface of a tapered body. a traverser that reciprocates in the axial direction of the take-up bobbin via a drive mechanism; a detector attached to the traverser to detect the detected member of the take-up bobbin; A limit switch provided on the traverser that emits a limit signal when the end of the winding bobbin with a smaller body diameter is reached, and when this limit signal is input, the traverser is moved from the end of the winding bobbin with a smaller diameter to the end with a larger diameter. A control signal that sends a control signal for moving the traverser to the drive mechanism of the traverser, and when a detection signal of the detected member by the detector is input, the traverser is reversely moved from the current position to the side with a smaller body diameter of the winding bobbin. traverser control means for sending the traverser to the drive mechanism of the traverser.

According to such a configuration, the reciprocating movement control of the traverser performed by the wire winding method described above is performed by the detection member provided by the winding bobbin, the detector mounted on the traverser, and the detector provided on the traverser. This can be done automatically using a signal generating mechanism consisting of a limit switch and a traverser control means that processes the signals of these signal generating mechanisms to control the reciprocating stroke of the traverser.

[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. As shown in FIG. 2, the winding bobbin 2 has a tapered body 3, and a reflective tape 4 is provided on the outer peripheral surface of the body 3 in the axial direction. Since the winding bobbin 2 rotates at high speed via a rotation mechanism (not shown), the reflective tape 4 does not need to be attached to the entire circumferential surface of the body 3; for example, one or a few strips of the reflective tape 4
may be provided on the outer peripheral surface of the body 3.

Reference numeral 5 denotes a traverser that reciprocates in the axial direction of the winding bobbin 2 via a drive mechanism (not shown).
A limit switch 6 is attached to one end corresponding to the smaller diameter of the body. Further, the traverser 5 is equipped with a reflective photoelectric switch 7 for detecting the reflective tape 4 on the winding bobbin 2 (arrow X in FIG. 2).

8 is a line pulley installed on the wire running line, 9
is an Akyum dancer, and the Akyum dancer 9 fluctuates either up or down when the winding amount of the wire rod 1 wound on the winding bobbin 2 changes and tension fluctuation occurs in the wire running line. A signal corresponding to the positional fluctuation is sent to a winding rotation control means (not shown) to accelerate or decelerate the rotational speed of the winding bobbin 2.

10 is a traverser control means for controlling the drive mechanism of the traverser 5, and the traverser control means 10
has a speed control function of inputting a linear velocity signal of the wire rod 1 and moving the traverser 5 in the axial direction of the winding bobbin 2 at a speed proportional to this linear velocity signal,
It has a control function that inputs the limit signal of the traverser 5 to drive and control the traverser 5 from the smaller to the larger body diameter of the winding bobbin 2, and further inputs the detection signal of the reflective photoelectric switch 7 of the traverser 5. It has a control function to reversely move the traverser 5 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.
Then, one end of the wire rod 1 is attached to the winding start position S.

In addition, the reversal time constant of the traverser control means 10 (the time from when the reflective photoelectric switch 7 of the traverser 5 detects the reflective tape 4 to when the traverser 5 is controlled to reverse drive) is set to an appropriate value. The reversing operation is set to be slightly delayed from the detection operation of the reflective photoelectric switch 7.

After setting such a winding setup, the traverser 4 is moved from the winding start position S to the winding bobbin 2 with a larger body diameter via the drive mechanism. In this first movement process of the traverser 5, the winding bobbin 2
Since the outer peripheral surface of the detected member 4 is not yet covered by the wire 1, the reflective photoelectric switch 7 immediately touches the detected member 4.
However, as mentioned above, the inversion time constant of the traverser control means 10 is set appropriately so that the inversion operation of the traverser 5 is slightly delayed from the detection operation of the reflective photoelectric switch 7. After the wire 1 is slightly wound around the winding bobbin 2, the traverser 5 reversely moves to the winding start position S side.

This reversal movement causes the traverser 5 to reach the winding start position S while the wire is wound onto the upper layer of the first winding layer 1a (second winding layer 1b). When the traverser 5 reaches the winding start position S, the drive mechanism of the traverser 5 is controlled via the traverser control means 10 which operates by inputting the limit signal of the limit switch 6 and the limit signal.
is again moved to the winding bobbin 2 which has a larger body diameter, and the wire rod 1 is wound up. That is, during the movement of the traverser 5, the reflective photoelectric switch 7 attached to the traverser 5 does not react in the area where the wire 1 is already wound (the area where the reflective tape 4 is covered with the wire 1). First, the wire rod 1 is wound up while the traverser 5 moves toward the side with a larger body diameter (the winding layer 1
c). When the traverser 5 reaches the outer peripheral surface of the winding bobbin 2 on which the wire 1 has not yet been wound, the reflective photoelectric switch 7 detects the reflective tape 4 and winds the traverser 5 via the traverser control means 10. Move it inverted to the starting position S side. As mentioned above, this reversing operation is slightly delayed from the detection operation of the reflective photoelectric switch, so the moving stroke of the traverser 5 becomes longer than the moving stroke of the previous stage, and the width of the wound layer gradually increases accordingly. The winding bobbin 2 becomes longer as the body diameter increases.

Thereafter, as the series of reversal movements A are repeated, the winding layers 1d, 1e, etc. of the wire 1 are formed one after another, and by the time the winding is completed, the winding layers 1d, 1e, etc. are approximately parallel to the axial direction of the winding bobbin 2. The winding layers 1a, 1b,
1c, 1d, 1e... are formed.

Therefore, according to this embodiment, since the wire rod 1 can be wound up while forming a winding layer substantially parallel to the axial direction of the winding bobbin 2, the accumulator dancer 9 provided on the wire rod running line can be wound violently. The rotational speed of the winding bobbin 2 can be controlled in a stable manner by the acquisition dancer 9 without fluctuations,
As a result, the wire can be automatically wound onto the tapered winding bobbin while preventing the wire 1 from coming off the roll, breaking, or unwinding due to taper.

[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.
