Wire coiling device and wire coiling method

Abstract

The invention provides a wire winding device and a wire winding method. When a wire is wound on a spool, the wire can be smoothly wound onto the spool with a uniform winding diameter and without a winding tensioning member. The wire winding device comprises a reciprocating member for enabling lateral movement of the wire or the spool; a wire winding member for winding the wire on the spool; a length measuring roller for measuring the length of the wire wound around the spool; a measuring member for measuring the angle of rotation of the spool; and a lateral movement turning position control member for calculating the average winding diameter (RC) of the central portion of the spool and the average winding diameter (RE) at both end portions of the spool, and determining the lateral movement turning position according to the difference value (delta S) between the product of the average winding diameter (RE) with the measurement area width (WE) of the average winding diameter at the end portions of the spool and the product of the average winding diameter with the measurement area width (RC) of the average winding diameter at the end portions of the spool.

Description

technical field [0001] The present invention relates to a wire coiling device and a wire coiling method for winding a wire around a reel by moving the wire or the reel laterally (Japanese: トラバース). Background technique [0002] Conventionally, in the technology of winding a wire such as a steel wire around a reel, a device for winding the wire is used. In order to arrange the wire in an orderly manner and to wind it flat, a position near the flange portion of the reel set by the operator is used. Move the direction change (Japanese: トラバースターン) position laterally to turn the wire back, and repeat this operation to perform wire coiling. [0003] When such a winding device is used to wind the wire rod around the reel, the coiled shape of the wire rod in the cross section in the width direction of the reel may sometimes have a thicker winding diameter or a smaller winding diameter. Here, the thicker winding diameter refers to a phenomenon in which the wire rod is wound more near ...

Problems solved by technology

Furthermore, in order to apply the coiling tensioner to an existing coiling device that does not have a coiling tensioner, it is necessary to newly add a coiling tensioner and a corresponding control system, and there is also a problem in terms of cost.

[0015] On the other hand, according to the study of the present inventors, when comparing the maximum value and the minimum value of the synchronous pulse ratio at the central part and both ends of the reel like the automatic lateral movement device disclosed in Patent Document 2, sometimes It is impossible to accurately grasp the amount exceeding the average winding diameter of the central part of the reel in the width direction near the end of the reel, and the amount smaller than the average winding diameter of the central part of the reel, and it is difficult to determine the appropriate lateral movement and redirection position

In addition, it has also been found that if it is difficult to accurately grasp the amount exceeding the average winding diameter of the central portion of the reel and the amount smaller than the average winding diameter of the central portion of the reel, there is a problem that the number of times of lateral movement and direction change until an equal winding diameter is obtained increases. question
