Therefore, not only is it necessary to be skilled in adjusting the pressing force of the winding pressure roller and the interlayer paper pressure roller, but also the adjustment work inevitably takes time.
[0008] In addition, when the winding operation of the wire is performed while the adjustment of the pressing force of the winding pressure roller and the interlayer paper pressure roller is incomplete, the position of the front end of the interlayer paper may deviate during the winding of the wire. In this case, it is necessary to temporarily stop the winding frame and manually adjust the position of the front end of the interlayer paper. Therefore, in order to wind a winding, the necessary man-hours inevitably increase, and the manufacturing cost of the winding inevitably increases.
[0009] Furthermore, in the conventional winding device, delicate adjustments are required every time a new winding is wound, and manual adjustment is required in the middle, so the adjustment and monitoring of the winding device are always arranged, Operators who manually adjust the winding state of the interlayer paper are indispensable, and it is difficult to automate the winding work

A bobbin winder can wind interlayer windings and insert interlayer paper to an interlayer without deviation of a front position of the interlayer paper or without wrinkle of the interlayer paper. The bobbin winder is provided with a guide device (310) which comprises a guide plate (312) placing the interlayer paper (L) in a top so as to guide; a pair of end face guide members (313) installed on the guide plate and limiting the position of two ends in the width direction of the interlayer paper on the guide plate; a pair of pressing rollers (315) respectively supporting the front end parts of the pair of end face guide members; under the state of moving the guide device (310) to a position of a bobbin frame (100), the interlayer paper is supplied to the bobbin frame by the guide device (310), the guide device (310) is exerted force by a cylinder (327); under the state of pressing the interlayer paper to the bobbin frame side; the bobbin is rotated and the interlayer paper L is wound on the bobbin frame when the guide device is along the bobbin frame.
Description
technical field [0001] The present invention relates to a winding device for winding a winding for electrical equipment having a structure in which layers of windings are wound and an interlayer paper is inserted between the winding layers. Background technique [0002] Generally, the primary-side winding of a transformer such as a columnar transformer has a structure in which multiple layers are wound and interlayer paper is inserted between the layer windings for insulation. As disclosed in Patent Document 1, a winding device for winding such a winding includes: a winding frame driving device having a main shaft concentrically holding the winding frame and a rotary drive device for rotationally driving the main shaft; Between the source and the reel driving device, the direction parallel to the axis of the main shaft is used as the traverse direction, and the traverse mechanism is used to traverse the wound conductor wound on the reel. [0003] Usually, the legs of the tr...
