Abstract

PURPOSE:To uniformize a flange side distance throughout a whole periphery and to prevent the occurrence of running aground and the drop of a cable by calculating a deviation between adjoining flange side distances measured at measuring points of a preceding winding, and effecting fuzzy control of a winding correcting means depending upon whether a calculating result is higher or lower than a set reference value. CONSTITUTION:Flange side distances D1, D2... between measuring points N1, N2..., set at intervals of a specified distance throughout the whole peripheral surface of a preceding winding, of the edge part of a cable 6 and a flange part 1a toward which winding is about to progress are measured one by one. From data of the flange side distances D1, D2..., a deviation between the flange side distances of adjoining measuring points is computed one by one. Based on deviations DELTAn1, DELTAn2..., winding scheduled points C1, C2,... are computed and set one by one so that a flange side distance of each measuring point of the subsequent winding of the cable 6 is uniformized, and the winding locus of the winding scheduled points of a subsequent winding is decided. The magnitude of the operation speed and an operation amount of a winding correcting means for the cable 6 is regulated depending upon whether a value between a decided winding scheduled point position and a subsequent winding scheduled point exceeds a predetermined reference value S.

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 bobbins.

[The issue we are trying to solve]

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. 4, for example, when the cable 101 is wound up to the vicinity of the collar 8100 and the final winding is performed at the wrapped portion, the final winding of the cable 101 and the collar 10 are performed.
0 If there is any part where the distance W between the cable 101 and the inner wall surface 100a does not have enough space for winding the cable 101, that is, the part where the edge distance W is smaller than the cable diameter d, the final winding During the work, a part of the cable 101 ends up climbing 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.

Various attempts have been made to prevent this phenomenon from occurring, but no effective solution has been found, and this remains a major problem.

In view of the above-mentioned circumstances, the present invention has been developed to correct the winding near the brim of the cable, and to perform aligned winding without causing partial depression or heaping up in the final winding of each layer of cable brim winding. The purpose is to provide a method for correcting the condition.

[Indispensable means to solve problems]

That is, the method of correcting the brim-wrapped state of a cable according to the present invention is as follows:
The flange distance between the bobbin flange over the entire circumference of the front winding and the current insertion point of the cable is measured at each measurement point set at a predetermined interval, and based on this measured data, each adjacent flange distance is measured. The deviation between the distances is calculated, and the expected winding point is calculated to equalize the edge distance at each measurement point in the next winding from the current winding point, and the winding locus is determined. When the scheduled point position has a larger deviation from the next scheduled wrapping point than a predetermined reference value, the cable wrapping correction means is quickly activated, and when the deviation is small, the cable wrapping correction means is actuated. is operated slowly to equalize and correct the edge distance over the entire circumference.

[Effect]

The method for correcting the brim-wound condition of a cable according to the present invention is to calculate the difference (deviation) between the brim-edge distances measured at each measurement point in the front winding, and calculate the difference (deviation) between the brim distances measured at each measurement point in the front winding. When the deviation is larger than the reference value, the cable entrapment correction means is operated quickly to correct the scheduled entrapment point by a certain amount, and when the deviation is smaller than the reference value, the entrapment correction means is operated slowly to correct the cable entanglement by a certain amount. By winding the cable while correcting the planned point, in other words, by performing fuzzy control with the winding correction means, it is possible to effectively prevent the cable from running aground or becoming stuck near the brim.

〔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 winding state of a cable according to the present invention, and as shown in FIG. The first step 2 and the second step 3
, a third step 4, and a fourth step 5.

In the first step 2, measurement points (N, ,
N,...) and the flange 1a (see Figure 2) that will no longer be caught (edge distance>D,, D2...)
・is successively measured, and in this embodiment, the brim distance is calculated from the image taken by the imaging camera.

In the second step 3, from the data about each edge distance (Dl, D2...) calculated in the first step, each adjacent measurement..., for example, N, and N2°, N2, N,, N3
and N4. The brim distances D1 and D2. D
, and D3. D, and D4. ...Distance differences (hereinafter referred to as deviations), that is, D2-D, (-8n2), D3

.

The third step 4 is based on the deviations Δn+, Δn2+ Δn3+, etc. calculated in the second step 3, as shown in FIG. Planned involvement points (CI, C2, C3) that can even out the distance
,...) are sequentially calculated and set to determine the winding locus drawn by each scheduled winding point of the next layer winding. It is designed to be operated by a microprocessor.

In the fourth step 5, the position of each scheduled wrapping point determined in the third step 4 is determined based on whether the position of each scheduled wrapping point is larger or smaller than a predetermined reference value (S) between the next scheduled wrapping point. The operation speed and the amount of operation of the entrainment correction means 6 are adjusted.

In this embodiment, a turntable (circuit) equipped with the bobbin 1 shown in FIG.
A motor (circuit) is used to rotate the
Fuzzy control is provided by the microprocessor.

Next, we will explain the third part about the brim roll correction method according to this embodiment.
A detailed explanation will be given with reference to the drawings.

For example, in Fig. 3, as shown in N, → N2, the distance difference between adjacent measurement points in the previous winding, that is, the deviation (Δn2
) is larger than the reference value (S), the next planned winding point C2 is set at a position that reduces this deviation.

In other words, the planned winding points should generally be separated by the radius dimension (r) of the cable 6 when the deviation in the flange distance between adjacent measurement points is 0, that is, when they are parallel to the flange. However, since the deviation (Δnz) at point N2 is extremely large, fuzzy control is applied to the previous motor so that it is separated by a distance d from the measurement point N at the previous round when winding the next round. The motor is quickly rotated by a predetermined angle.

Note that the separation distance d2 from the measurement point N2 of the expected winding point C2 is uniquely determined by, for example, the following calculation formula.

For example, like N2 → N3, the distance difference between adjacent measurement points in the previous winding, that is, the deviation (Δn,) is the reference value (S
), the planned winding point C5 is set by taking this deviation into consideration as is.

In this case, fuzzy control is applied to the previous motor to rotate it slowly and by a predetermined angle so that the cable 6 is separated by a distance d from the measurement point N3 at the previous winding.

Note that the separation distance d from the measurement point N of the planned winding point C5 is uniquely determined by the following arithmetic expression %.

〔effect〕

As explained above, according to the method for correcting the brim-wound state of a cable according to the present invention, the difference (deviation) between adjacent brim distances measured at each measurement point in the previous winding is calculated. Depending on whether this deviation is larger or smaller than a preset reference value, the winding correction means is fuzzy controlled, thereby making the brim distance approximately equal over the entire circumference, and reducing the length of the cable at that point. It is possible to effectively prevent the vehicle from running over or falling.
