Abstract

PURPOSE:To perform stable alignment winding through execution of rapid coping with a hourly changing cable winding position by detecting a root part based on a picture on which the winding state of a lower layer cable is photographed and winding an upper layer cable along the root part. CONSTITUTION:When a traverser 7 to wind a cable 2 is moved from the right to the left, a projecting device 5 performs oscillation following movement of the traverser. The illuminated spot especially in the vicinity of a winding point of the cable 2 is photographed by a photographing camera 8 to detect a root part B, i.e., a boundary portion between cables 2b and 2c at a lower layer cable adjacent to a forwardmost winding part 2a of an upper layer cable, from a picture. A control part detects a right edge part B of a small dark part B in a dark region as the root part when the traverser 7 is moved in a dark region where a dark part region having a wide width in a direction Y and a dark part region having a narrow width are brought into contact with each other. The position of the traverser 7 is controlled so that a distance W between the root part B and the flange side of a bobbin 1 coincides one by one with a distance D between the traverser 7 and the flange.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an aligned winding method for cables in which the cables are wound in a correctly aligned state when the cables are wound around a bobbin.

[Conventional technology]

When winding a cable around a bobbin, take into consideration workability when unwinding the cable, and make sure to wind the cable in an orderly manner in the correct alignment (hereinafter referred to as alignment) so that the cable can be unraveled smoothly. It is an important issue to make the paper roll (called "rolling").

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

[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 vehicle to run aground. That is, as shown in FIG. 5, for example, this means that the cable 1
01 is wound and the final winding is performed in the winding part, a part where the distance W between the final winding of the cable 101 and the inner wall surface 100a of the collar part 100 does not have enough space to wind the cable 101, In other words, if there is even a part of the cable whose brim distance W is smaller than the cable diameter d, part of the cable 101 will climb up one stage during the final winding operation. If this condition is left as is, there is a risk that the cable will become undulated or tangled, causing the cable to become uncoiled and winding. This has become a problem.

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

In view of the above-mentioned circumstances, the present invention provides an aligned winding method for cables that can perform aligned winding while appropriately correcting and controlling the position of the cable winding point according to the winding strength of the lower layer portion of the cable. The purpose is to

[Means to solve the problem]

That is, in the cable winding method of the present invention, illumination light is projected into an area where the cable is to be wound, including the cable winding point on the body of the bobbin on which the cable is wound, and the illumination light is used to shape the cable. The area near the cable winding point, including the dark area in the lower layer that is formed in response to the noise, is imaged, and predetermined arithmetic processing is performed based on this captured image to form a boundary between cables in the lower layer near the cable winding point. The troughs are detected and positioning is performed one by one so that the cable winding points coincide with each other along the locus of the troughs.

[Effect]

The cable winding method of the present invention detects valleys in the cable winding state of the lower layer, that is, depressions between cables, and winds the next layer of cable toward the detected valleys. This allows the cables to be wound in a stable manner at all times and wound in an aligned manner.

〔Example〕

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

FIG. 1 shows a method for winding a cable in an aligned manner according to the present invention. This method involves winding a cable 2 wound around a bobbin 1 as shown in FIG. 2 in an aligned manner on the upper layer thereof. This step consists of a first step 3, a second step 4, a third step 5, and a fourth step 6.

The first step 3 is to illuminate the wrapped cable 2, and in this embodiment, a light projecting device 5 as shown in FIG.
．． 6, illumination light is projected onto the wrapped cable 2 at a specific angle in one direction. The light projecting device 5 projects illumination light from an oblique direction toward an area near the current winding point of the wound cable 2 on the bobbin 1, which changes every moment, so as to match the unevenness of the cable 2 as shown in FIG. In this embodiment, the traverser 7 that wraps around the cable 2 operates when it moves from the right to the left, and follows this movement to perform a swinging motion. ing. Note that the light projection device 6 is activated when the traverser 7 moves in the opposite direction to perform a similar operation.

The second step 4 is to take an image of the illuminated wrapped cable 2, particularly in the vicinity of the wrapping point (within the dashed line area in FIG. 3), using the imaging camera 8 shown in FIG. One for tape recorders is used.

In the third step 5, the valley B, that is, the boundary region between the cable 2b and the cable 2C in the lower layer cable adjacent to the first winding portion 2a of the upper layer cable in FIG. 3 is detected from the image captured by the imaging camera 8. and
It is comprised of a control section (flash) using a microprocessor or the like that performs predetermined image processing based on the image signal captured by the imaging camera 8. And this control department is
As shown in FIG. 3, this is a dark area where a large dark area in the Y direction (hereinafter referred to as a large dark area α) and a small width dark area (hereinafter referred to as a small dark area β) are in contact with each other. When the traverser 7 moves leftward (rightward), the left end (right end) edge B of the small dark area β in the dark area is detected as a valley.

In the fourth step 6, the cable 2 is wound in line with the valley B, and in this embodiment, the cable 2 is wound around the valley B and the bobbin 1.
The position of the traverser 7 is controlled so that the distance from the traverser 7 to the brim successively matches the distance W to the brim.

In addition, in this embodiment, the winding state of the cable 2 in the lower layer has been described as that in which the cable 2 is wound in close contact with the adjacent cable without any gap, but for example, as shown in FIG. If the winding condition of the midway (lower layer) cable 2 is disturbed during winding toward the front, the following method is used to deal with it. That is, in this case, when winding the next (upper layer) cable 2' to the left, some valleys (marked with
When it is displaced in a direction (rightward) opposite to the winding direction (in this case leftward) in a certain forehead area (γ) and approaches the first winding part by a certain distance or more, the detection data in that area (7) is In addition to cutting, a smooth curve (marked with O) may be used to connect the valley portion detected after passing through this region (r).

〔effect〕

As described above, according to the method for winding cables in an aligned manner according to the present invention, an image is taken of the lower layer cable winding state, a valley is detected based on the captured image, and the upper layer cable is wound along the valley. Since the cable is wound in the cable, it is possible to quickly cope with the ever-changing cable winding position and perform stable aligned winding.
