Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aligned winding device for manufacturing coils, transformers, etc. by a winding shaft rotation method, and particularly aims to improve alignment.

In the conventional aligned winding method, the copper wire is controlled by the supply side of the copper wire or the shape of the winding frame. Since the traverse is delayed by a predetermined amount, the traverse width must be made larger than the reel width or the wire guide roller must be temporarily stopped, making adjustments difficult and making it difficult to absorb variations in wire diameter. had.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 1 to 4.

In Figures 1 and 2, 1 is a winding shaft that holds a bobbin 2, 3 is a winding motor that drives the winding shaft 1,
4 is a tail stock for preventing center shift of the winding shaft 1; 5 is a bearing that holds the winding shaft 1; 6
is a plate holding the tailstock 4 and bearing 5. 7 is an air cylinder for swinging the plate 6 around the fulcrum pin 8; 9 is a bearing that holds the plate 6; 10 is a flexible joint that can transmit power even when the plate 6 swings; 11 is a It is a spline shaft that can transmit power even when the plate 6 swings. 12 is a spline bearing;
13 and 14 are timing pulleys for transmitting the power of the winding motor 3; 15 is a timing belt that transmits power between the timing pulleys 13 and 14; 16 is a bearing that holds a spline bearing; 17 is a plate The cam followers 18 and 18' supporting the plate 6 are stoppers for the plate 6 to swing through a certain angle. 19 is bobbin 2
21 is a ball screw that moves the slider 22 holding the guide roller 19 at a constant pitch; 23 is a ball screw 21 that guides the copper wire 20;
24 is a traverse motor that drives the ball screw 21, 25 and 26 are timing pulleys for transmitting the power of the traverse motor 24, and 27 is a timing belt that transmits power between the timing pulleys 25 and 26. A traverse device is constructed from the above, and 28 is a base holding the above-mentioned parts.

In the above configuration, to explain the operation, bobbin 2
The copper wire 20 is held in a part of the bobbin 2, and the winding of the copper wire 20 on the bobbin 2 is started by starting the winding motor 3. The traverse motor 24 starts rotating in synchronization with the winding motor 3, the slider holding the guide roller 19 feeds the copper wire 20 at a fixed pitch, and the bobbin 2 is moved at a fixed angle by the air cylinder 7. Swing and start aligning winding. The direction in which the bobbin 2 swings is as shown in FIG.
When the copper wire 20 traverses to the right, it swings downward to the right, and as shown in FIG. 4, when the copper wire 20 traverses to the left, it swings upward to the right. If the bobbin diameter is D and the copper wire diameter is d, the swing angle may be set near θ where θ=tan ⁻¹ (2d/D). As described above, by setting the swing angle of the bobbin 2, the copper wire 20 can be wound in alignment while following the copper wire that was first wound.

Therefore, since the copper wire 20 is closely wound, it is possible to easily wind the wire in alignment, which is effective in improving quality.

In addition, in the above embodiment, the traverse device is
Although a ball screw is used, a cam may also be used, as long as the guide roller moves at a constant speed.

As described above, according to the present invention, by swinging the bobbin at the return section of the copper wire, braking is simplified and aligned winding is easily possible, which is effective in improving alignment and improving quality. It is.
