Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire rod traverse mechanism that is particularly suitable for a winding machine that winds a bobbin having a split horizontal winding. It is an object of the present invention to provide a traverse mechanism that can be reliably guided and has a simple structure.

That is, the traverse mechanism according to the present invention is characterized in that a sleeve having a hook is movably attached to the outer periphery of a chuck that rotates while holding a bobbin, and the wire is guided by the hook. be.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings, taking as an example a case where a high frequency coil is wound around a bobbin.

FIG. 1 shows a high-frequency coil in which a plurality of annular winding grooves 11 are formed on a bobbin 1 before being wound.

Reference numeral 12 denotes a vertical groove for traverse provided to cross the plurality of winding grooves 11, and in the illustrated coil, four vertical grooves 12 are provided around the bobbin 1.

2 is a base to which the bobbin 1 is fixed, and 3 is a terminal provided on the base 2 as a shield.

FIGS. 7 and 8 show the high frequency coil installed in a winding machine equipped with a traverse mechanism according to the present invention. In this example, a winding machine equipped with two chucks is shown. FIG. 2 is an enlarged view of the chuck portion. In FIGS. 7, 8, and 2, reference numeral 4 indicates a rotatable chuck that holds the bobbin 1 at its front portion, and 5 indicates a substantially cylindrical sleeve attached to the outer periphery of the chuck 4.

The rear of the chuck 4 is connected to a rotating shaft 45, which is driven by a motor (not shown). A spring 55 (FIG. 7) is attached to the inside of the sleeve 5, and this spring 55 pushes the sleeve 5 in the X direction to keep it in close contact with the front surface of the push plate 72 at all times. The sleeve 5 has two rods 7
The chuck 4 can be moved and stopped with high precision in the axial direction of the chuck 4 in the x-X' direction by means of a pulse motor 80 via the press plate 72 and the rear plate 74 which are connected at the 0-point. That is, the male screw 82 fixed to the rotating shaft of the pulse motor 80
is engaged with a female screw 76 formed in the center of the rear plate 74, so that it is pushed by the push plate 72, which moves in accordance with the rotation of the pulse motor 80, and moves in the x-X' direction. A gear 53 is provided at the rear of the sleeve 5, and this gear 53 meshes with a rack 90 having a planar gear.

The rack 90 is connected to a piston rod 94 of an air cylinder 92, and by moving the rod 94 in the Y-Y direction, the sleeve 5 is spread around the axis of the chuck 4. There is a notch 5 at the tip of the sleeve 5.
0 is formed, and the sleeve 5 is provided with a side surface portion 51 along the wisteria direction so as to face this notch portion 501,
A hook portion 52 protruding in a direction intersecting the axis is formed at one end of the side surface portion 51.

Next, the operation of the traverse mechanism of the present invention will be explained.

First, the chuck 4 is rotated to wind the wire 6 into the first winding groove 11. At this time, the gear 53 at the rear of the sleeve 5 engages with the rack 90 and is held so as not to rotate. When the winding to the first winding groove 11 is completed, the pulse motor 80 is rotated to move the sleeve 5 forward in the right direction (X' direction) and cover the bobbin 1 as shown in FIG. . At this time, the wire rod 6 being drawn out from the unillustrated feeding drum is made to pass through the inside of the notch 50 of the sleeve 5. The notch 50 of this embodiment is pre-formed to a size that does not cover all the winding grooves 11 of the bobbin 1 even when the sleeve 5 covers the lower end of the bobbin 1. Next, the rod 94 of the air cylinder 92 is
By retracting the sleeve 5 in the direction ', the sleeve 5 is rotated in the direction of the arrow (Fig. 3), and then by retracting the sleeve 5 to the left (X direction), the longitudinal groove 12 is moved as shown in Fig. 4. The wire rod 6 is engaged with the fishing part 52 directly above. Then, by rotating the pulse motor 80, the sleeve 5 is further moved to the left (x direction), and the second winding groove 11 to be wound next is moved.
When the copper part 52 reaches the position shown in FIG. 5, the sleeve 5 is stopped. Thereafter, the chuck 4 is slightly rotated to guide the wire 6 into the second winding groove 11 via the vertical groove 12. The above operation is automatically performed using a pulse motor, a air cylinder, or a cam. It will be automatically guided into the winding groove 11.

After this, the rod 94 is moved forward in the Y direction to release the engagement between the fishing part 52 and the wire rod 6, and the sleeve 5 is returned to the left as shown in FIG. 6 by the pulse motor 80, or As shown in FIG. 3, the chuck 4 is rotated while the wire rod 6 passes near the center of the notch 50,
Just wrap wire 6 around 1. Furthermore, the third winding groove 11
If you want to wind the wire continuously, repeat the above operation. When the lead of the wire rod 6 after winding is pulled out toward the terminal 5 through the vertical groove 12, the side surface 51 of the sleeve 5 facing the notch 5 can be used as a guide. In addition, although the above-mentioned example explained the case where a high frequency coil is wound, the present invention can of course be applied to other coils, transformers, etc. that have divided winding grooves on the bobbin. As described above, the traverse mechanism of the winding machine according to the present invention is a winding machine that winds a wire around a bobbin having a plurality of winding grooves and a vertical groove that crosses the winding grooves, and the traverse mechanism holds one end of the bobbin at the tip. A chuck that can rotate around the same axis as the central axis of the lever bobbin, and a cylindrical part with an inner diameter slightly larger than the diameter of the bobbin, which is attached to cover the outer circumference of the chuck and rotates around this axis. The sleeve is movable and can be moved in all directions on the axis up to the bobbin, and has a notch and a hook at the tip of the sleeve, and the fishing part engages the wire rod during winding to move the sleeve. This structure is designed to guide the wire to a predetermined position on the bobbin.

According to the present invention, since the traverse mechanism can be configured extremely compactly, it is possible to arrange a large number of chucks adjacently at narrow intervals.

Further, since the copper portion is provided close to the winding groove, the wire can be guided with high precision, and even with a split winding groove bobbin having a narrow winding groove width, accurate traverse operation can be obtained.
