Abstract

PURPOSE:To perform alignment winding preventing the occurrence of a partial drop and winding aground during transfer to a next layer by suppressing a gap between cables of adjoining windings to a specified value and setting a distance between a final winding cable and a bobbin flange part to a value specified times as large as a cable diameter. CONSTITUTION:First, in a specified region, i.e., a parallel winding regulating area, spaced away from a flange part 3a of a bobbin 3 by a given distance, a flange side distance between each winding of a cable 4 having a winding diameter D and a flange part 3a is kept in a specified state, i.e., levelled in a parallel winding state. Measurement of operation and the magnitude of an operation amount of a winding correcting means for the cable 4 are regulated depending upon whether each winding scheduled position where a flange side distance at each measuring point at the subsequent peripheral winding of the cable 4 wound therefrom is uniformed is higher or lower than a reference value S predetermined between the winding scheduled position and a winding scheduled point next to the subsequent winding scheduled point. As correction is made in a state that a gap W between cables 4 of adjoining windings is set to a value within 1/5D of the diameter D of the cable 4, a flange side distance W of the cable 4 of a final winding is set to a value being approximate 1/2D throughout a whole periphery.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a method for measuring the winding state of a cable at the edge of the bobbin, which can correct the winding state of the cable at the edge of the bobbin when the cable is wound around the bobbin. It is about the method.

[Conventional technology]

When winding a cable around a bobbin, consider the workability when unwinding the cable, and in order to unwind the cable smoothly, wind the cable in the correct order (hereinafter referred to as "aligned winding"). It is an important issue to make this happen.

Therefore, various means and methods have been proposed and developed to wind cables in an aligned manner around such boheens.

[Problem to be solved]

However, when winding cables around this bobbin in an aligned manner, the bending tendency of the cable itself, changes in diameter dimensions, deformation of the diameter cross section, flatness of the bobbin flange, and installation conditions may cause problems, especially at the brim. This is a troublesome problem as it often causes the phenomenon of sticking up. That is, as shown in FIG. 8, for example, when the cable 101 is wound up to the vicinity of the flange 100 and the final winding is performed in the winding layer portion, the final winding of the cable 101 and the flange 100 are performed.
If there is even a part where the distance W between the inner wall surface 100a and the cable 101 does not have enough space for winding the cable 101, that is, there is a part where the edge distance W is smaller than the cable diameter d, the final winding work will be difficult. At this time, a part of the cable 101 climbs up one level. If this condition is left as it is, there is a risk that the cable will become undulated or tangled, making it impossible to wind it in an aligned manner. It's becoming a problem.

Therefore, although various attempts have been made to prevent such phenomena from occurring, no effective solution has yet been found, and this remains a major problem.

In view of the above-mentioned circumstances, this invention secures a predetermined width of brim space at the final winding of each layer while sequentially correcting the winding within a predetermined area near the brim of the cable, thereby making it easier to transfer to the next layer. The object of the present invention is to provide a method for correcting the brim of a cable, which allows the cable to be wound in an aligned manner without causing any part of the cable to fall in or stick up.

[Means to solve the problem]

That is, the method for correcting the edge of a cable according to the present invention is such that when the cable is wound toward the edge of the bobbin, the winding position is adjusted so that the gap between the cables does not widen more than a predetermined value with respect to the cable diameter. At the same time, the winding position is successively corrected so that the distance between the cable and the flange becomes 172 times the cable diameter at the final winding of each layer.

[Effect]

The cable brim correction method of the present invention suppresses the gap between adjacent windings of the cable within a certain value, and
The distance between the final winding cable and the bobbin flange is set to half the cable diameter, so that when winding the cable to the next layer, the cable will partially drop at or near the first winding part. It is possible to perform aligned winding while preventing the windings from stacking up or climbing up.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a method for correcting the brim of a cable according to the present invention, which consists of a first step 1 for performing parallel winding, and a constant distance between the brim in the final winding. and a second step 2 of aligning the two.

In the first step 1, the flange 3a is applied to each layer of winding of the cable 4 (diameter D) to be wound within a certain area (parallel winding adjustment area) spaced a predetermined distance from the flange 3a of the bobbin 3 shown in FIG. (hereinafter referred to as the flange distance) is in a constant state, that is, parallel winding. A winding state correction method is adopted.

(In addition, in this Figure 2, for convenience of explanation, the cable 4
The diameter is indicated by a single line. ) That is, this method is
As shown in FIG. 3, step 1-a step 5 and step 1-b
Step 6, 1-0 step 7, 1-d step 8
It is composed of.

Step 1-a step 5 consists of measurement points (N
,,N,,...) and the flange 3a (see Figure 4) that is about to be rolled in (edge distance) W
r, W2, . . . are sequentially measured, and in this embodiment, the brim distance is calculated from an image captured by an imaging camera.

In the 1-b step 6, in the 1-a step 5,
From the data about each calculated brim distance (W,, W2...), each adjacent measurement point, for example N1 and N2
．． N2 and N3. N, and N4. The brim distance W, and W2, W2 and Ws, and W3 and W.

Each distance difference (hereinafter referred to as deviation), that is, W2 Wl (=ΔT12), Ws

. . . is calculated sequentially, and in this example,
This is done using a microprocessor.

The 1-c step 7 calculates the deviation Δn + + Δn 2 + Δn 3 + calculated in the 1-b step 6.
・、.

Based on..., as shown in Fig. 5, the planned winding point (C,...
C,, O3...) are sequentially calculated and set to determine the winding locus drawn by each winding scheduled point of the next layer winding.In this embodiment, the second step 3 is The planned winding point along with the deviation is calculated by the microprocessor.

The 1-d step 8 determines whether the position of each scheduled entrapment point determined in the 1-c step 7 is larger or smaller than a predetermined reference value (S) between it and the next scheduled entrapment point. Accordingly, the operation of the cable 4 entanglement correction means is measured and the magnitude of the operation amount is adjusted. That is, in this step 8, when the deviation is larger than the reference value (S), the operation of the entrainment correcting means is controlled to be fast and large, and when the deviation is small, it is controlled to be slow and small, thereby controlling the operation of the entrainment correction means for all the same volumes. The edge distance W is made substantially constant (parallel winding). In this embodiment, a motor (circle) for rotating left and right a turntable (circuit) on which the bobbin 3 shown in FIG. It is designed to be fuzzy controlled.

In the second step 2, as shown in FIG. 6, the gap (W) between each winding of the cable 4 is 1/
The brim distance W of the final cable 4 is approximately 1/2D over the entire circumference while being modestly corrected within 5D. In this example, as shown in the following table, each winding center position (0) is set at a predetermined distance (W) from the brim edge.
In other words, in FIG. 7, the shaded area (S, , S2...
), the position of the winding point for each cable 4 is controlled within the limit adjustment range in FIG. 2.

Table Next, the second step 2 of this embodiment will be explained in detail with reference to the previous table and FIGS. 2 and 7.

In addition, in the brim edge correction method in this embodiment, as shown in FIG. It is assumed that

The brim correction method in the second step 2 is performed as shown in FIG. 7, as shown in FIG.
, the allowable area (S) is 1/5 the distance between each cable 4.
In order to keep it within D, it is set so that it narrows as it approaches the final volume.In other words, as shown in Figure 2, it is set to narrow from the last volume (n) to the 6th volume (nth
-5 turns), the flange distance (W) is 6.0D ~
7. The winding center position (O3) can be freely set anywhere within the OD range (free adjustment range). That is, no matter where the winding center position is set at least in the area to the left of the free adjustment area in FIG. 2, the cable 4 of each winding is within the diagonal line shown in FIG. By gradually narrowing down the center position O, it is possible to reliably secure the brim distance W to 1/2D in the final winding.

Therefore, for example, if the center position of the cable of winding n-5 is at 6.9D as shown in Fig. 2, the center position of cable 4 of each winding should be placed within the shaded area shown in Fig. 7. By doing this, for example, the gap between each winding cable 4 can be reduced to 0.
By winding the cable so as to set it to 18D, the distance (W) at the brim of the final cable 4 can be secured by just 0.5D.

〔effect〕

As explained above, according to the cable brim correction method according to the present invention, the gap between adjacent windings of the cable can be suppressed within a certain value, and the distance between the last winding cable and the bobbin collar can be reduced. It is set to half the cable diameter, and this effectively prevents the cable to be wound in the next layer from partially falling down at or near the beginning of winding, and ensures that the winding is done in an aligned manner. You will be able to do this.
