Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a large-capacity wire winding machine suitable for continuously winding thin wire such as enameled wire over a long period of time.

Conventionally, large-capacity filament winding machines that wind thin filaments have rotated the winding bobbin, but with this type of system, the winding diameter changes over a wide range and minutely, and therefore the winding diameter changes over a wide range and minutely. The rotational speed of the take-up bobbin also changes over a wide range and minutely.

However, changing the rotational speed of the winding bobbin over a wide range and minutely requires a complex and expensive drive control circuit, and if the minute changes have poor followability with the winding diameter, wire breakage accidents may occur. There were some drawbacks that could easily occur. SUMMARY OF THE INVENTION An object of the present invention is to provide a filament winding machine that winds a thin filament with constant tension without rotating a winding bobbin.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a wire winder 10 according to an embodiment of the present invention. A machine frame 16 is provided with a base 14 on which a winding bobbin 12 is detachably mounted.

An upper frame 20 is attached to the machine frame 16 via a support 18,
A guide means 22 consisting of a guide roller supported near the central axis of the winding bobbin 12 is provided on the upper frame. The filament body 24 is guided by the winding bobbin 12 by this guide means.
guided downward from the central axis of Striatal attachment means 2
6 is an inverted L rotating around the outer periphery of the winding bobbin 12, which has a hollow rotating shaft 28 that rotates around the central axis of the winding bobbin 12 and a boss 30a attached near the lower end of the hollow rotating shaft.
A guide member 32 consisting of a guide roller that guides the twill body 24 from the guide means 22 so as to be wound around the winding bobbin 12 is attached to the tip of the arm 30.

The hollow rotating shaft 28 is flanged to a hollow main shaft 36 attached to the upper frame 20 via a bearing 34, and a pulley 36a is integrally formed on the hollow main shaft 36. A torque motor 38, which is a rotational drive source, is attached to the upper frame 20', and its output booley 38a and a pulley 36a of the hollow main shaft 36 are connected to each other.
A belt 39 is stretched between the two. Therefore, when the torque motor 38 rotates, the arm 30 rotates, and the filament 24 is wound around the winding bobbin 12 by a guide roller serving as a guide member 32 that rotates while revolving around the winding bobbin 12. Note that the filament 24 reaches the guide member 32 of the wire winding means 26 from the guide means 22 through a through hole 28a provided in the inside of the hollow main shaft 36 and the flange of the hollow rotating shaft 28. The traverse means 4 includes a cross-screw shaft 42 that extends inside the rotating shaft 28 and is arranged on the central axis of the take-up bobbin 12, and a traverse claw 4 that is attached to the boss 30a of the arm 30 by a screw 44 and meshes with the cross-screw shaft 42.
It consists of 6. As shown in the figure, the cross screw shaft 42 is supported by the hollow rotary shaft 28 via upper and lower bearings 48, 48', and a lower end extension 42a extending from the lower bearing 48' has a keyway 50' for carrying a key ( A rotation stopper 52 having a rotation stopper (not shown) is fixed by a threaded screw 64, and a kerating pin 56 that fits into the kernel hole of the winding bobbin 12 is attached to the base plate portion of the rotation stopper 52. Therefore, the cross screw shaft 42 is fixed to the winding bobbin 12 in alignment with its central axis, and the hollow rotating shaft 28
Rotate around. As shown, the traverse pawl 46 passes through a vertical guide groove 58 (see FIG. 2) of the rotating shaft 28, and can move up and down with respect to the rotating shaft.
Next, to explain the operation of the above-mentioned wire winding machine, first, loosen the thumbscrew 54, raise the rotation stopper 52, and move the winding bobbin 12 upward.
is mounted on the base 14, the rotation stopper 52 is lowered, the kerating pin 56 is inserted into the kerating hole of the winding bobbin, and the wing screw 5 is inserted.
Tighten 4.

Next, the filament 24 is fixed to the winding bobbin 12 through the guide member 22, the through hole 28a, and the guide member 32 of the winding means. When the post-rotation drive source 38 is rotated, the guide member 32 of the winding means 26 rotates while revolving around the winding bobbin 12 and winds the filament 24 around the winding bobbin. As the traverse means 4 rotates the rotating shaft 28, the traverse pawl 46 rotates along the upward thread of the cross screw shaft 42, so that the arm 30 and the guide member 32 to which the traverse pawl 46 is attached gradually rise. When the traverse pawl 46 reaches the upper end of the screw of the cross screw shaft, it rotates along the downward screw, so that the arm 30 and the guide member 32 gradually descend. In this manner, the guide member 32 reciprocates along the axis of the pick-up bobbin to distribute the filament 24.
FIG. 3 shows another embodiment of the present invention. In this embodiment, a hollow rotating shaft 28 is attached to an intermediate cylinder 6 fixed to a hollow main shaft 36 so as to be slidable in the axial direction.
It is biased upward by a spring 62 disposed between the lower end spring receiver 60a and the upper end spring receiver 28b of the hollow rotation shaft 28, but during winding, the kerating pin 56 of the rotation stopper 52 is pressed against the kerating of the winding bobbin. It is held in this operating position by a follow-up bolt 64 which descends against a spring 62 to engage the hole and is screwed from the intermediate tube 60.

Further, in this embodiment, the hollow rotating shaft 28 and screw shaft 4
A speed reducer 66 is provided between the rotary shaft 28 and the cross screw shaft 62 to rotate the cross screw shaft 62 at a reduced speed in the same direction as the rotating shaft 28. In this way, the traverse movement of the arm 30 and the guide member 32 is performed at a pitch smaller than the pitch of the cross screw shaft 42.
When the hollow rotating shaft 28 , that is, the arm 30 rotates once around the winding bobbin 12 , the arm 3 rotates by the outer diameter of the filament 24 .
The pitch of the cross screw shaft 42 is determined so that the pitch of the cross screw shaft 42 can be raised. For this reason, it is necessary to reduce the pitch of this cross screw shaft 42 as the outer diameter of the filament body 24 becomes smaller. However, when the pitch of the cross screw shaft 42 is decreased, the engagement state between the thread groove and the traverse pawl 46 The traverse claw 46 may come off the thread groove, resulting in an uneven traverse amount of the arm 30. Also, since there are two notches per pitch, the strength of the threaded portion may be weakened. Furthermore, since thread cutting becomes troublesome, there is a limit to reducing the pitch of the cross screw shaft 42.
However, when the cross screw shaft 42 is decelerated and rotated in the same direction as the rotation shaft 28 by the reducer 66 as shown in the figure, for example, the cross screw shaft 42 is rotated in the same direction as the rotation shaft 28.
When rotating at a speed of 1'2 of the speed of
In other words, the pitch of the screw shaft 42 can be set to twice the pitch of the traverse motion. Similarly, the cross screw shaft 42 is rotated 3/3 in the same direction for one rotation of the arm 30.
After four revolutions, the traverse movement will be performed at a pitch of 1'4 relative to the pitch of the cross screw shaft 42. In this way, the arm 30 can be traversed at a small pitch without reducing the pitch of the cross-screw shaft 42, and therefore the traverse pawl 46 does not come off the thread groove, and the strength of the cross-screw shaft 42 is reduced. This also makes thread cutting easier. The reducer 66 is
In the illustrated embodiment, an internal gear 68 provided at the lower enlarged end of the hollow rotating shaft 28, a stationary gear 70 provided at the detent 52, and a space between the internal gear 68 and the stationary gear 70. This is a planetary gear mechanism 73 consisting of a planetary gear 72 and a planetary gear 72 arranged as shown in FIG. It is attached to the lower end flange 42a of the threaded shaft 42. Therefore, when the hollow rotary shaft 28 rotates, the planetary gear 72 revolves while rotating, decelerating the cross screw shaft 42, and rotating in the same direction. Note that the rotation stopper 52 is supported by the cross screw ball 42 by a bearing 74. According to the present invention, as described above, the winding bobbin is fixedly mounted on the base, and the filament is wound by the winding means having the guide member that revolves around the winding bobbin. Since the filament can be wound with a constant tension and a heavy winding bobbin drive source and its speed control circuit are not required, the equipment cost is low and the linear speed can be increased.

The winding bobbin can be easily attached and detached because the rotating shaft does not pass through the winding bobbin and there is nothing around the winding bobbin that will obstruct the attachment and detachment. Furthermore, since the winding means is traversed by the traverse means using its rotational force, a separate traverse drive source is not required, and the pitch can be made finer by a reduction gear. Suitable for large-capacity winding.
