Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention provides a wire feeding pitch of a feeding bobbin that automatically guides a feeding line to a feeding bobbin that feeds a wire wound on a winding surface of a bobbin. The present invention relates to an automatic speed following line guide device.

[0002]

[Prior art]

 Conventionally, when a wire is fed from this type of feeding bobbin, the feeding point of the wire reciprocates in parallel along the feeding bobbin surface in accordance with the feeding of the wire.

In particular, as shown in FIG. 7, as the feeding point of the wire w moves from the center of the winding surface of the feeding bobbin 21 to the end, the feeding direction of the wire w with respect to the feeding bobbin 21 gradually increases. The wire w becomes sharp, and the wound wire w may be entangled or snagged on an adjacent wire to be unwound, thereby hindering the smoothness of the unwinding operation, or distorting the wire or damaging the surface.

[0004] In order to solve the obstacle, it is only necessary to make the direction of feeding the wire w as perpendicular to the feeding surface as possible. For this purpose, the position of the sheave 22 that first guides and supports the unwound wire w may be set at an infinite position from the unwinding bobbin 21, but in reality, as shown in FIG. It will be set as far away as possible.

[0005] In this case, there is a disadvantage that the structure is inevitably increased in size, and therefore a large installation space is required for installation.

[0006]

[Problem to be solved by the invention] Therefore, the present invention is to make it possible to always make the direction of the wire fed from the wire feeding point reciprocating in parallel along the surface of the feeding bobbin perpendicular to the feeding bobbin. The gap between the sheave that first guides and supports the unwound wire and the unwinding bobbin can be reduced, which contributes to downsizing of the structure and the installation space, as well as distortion and surface distortion of the wire. The purpose of the present invention is to obtain an automatic follow-up line speed guiding device for a wire feeding pitch speed of a feeding bobbin so as not to damage the feeding bobbin.

[0007]

 The present invention has been made in view of the above point of view, and is installed in parallel with a required interval with respect to a feeding bobbin mounting shaft for mounting a feeding bobbin on which a wire is wound in a bobbin winding space. And a reciprocating device that can reciprocate with respect to the driving rotary shaft, wherein the reciprocating device has an inner ring surface having an inner diameter larger than the diameter of the driving rotary shaft. The rotating shaft is penetrated into the inner space of the inner ring surface of the plurality of rotating wheels, and the portions where the inner ring surfaces of adjacent rotating wheels press against the rotating shaft are on opposite sides. The gear is coaxial with a mounting shaft for rotatably mounting the rotating wheel to a body so that the rotating wheel can be interlocked at a supplementary angle, which is always a symmetric angle with respect to the rotating shaft. Is fixed, one of the rotating wheels A distal end of a shaking rod having a required length oriented in a direction substantially parallel to the rotating surface of the rotating wheel is fixed, and a leading portion for inserting a wire is provided at the tip of the shaving rod. It is an object of the present invention to provide a wire feeding pitch speed automatic following line guide device for a payout bobbin, in which a lead-out portion is disposed at a part of a vessel where is located.

[0008]

[Embodiment of the invention]

 Hereinafter, the configuration of the present invention will be described in detail with an operation with reference to the drawings. First, FIGS. 1 to 4 show one embodiment of the present invention. A feeding bobbin 1 on which a wire w is wound around a winding space of a bobbin is rotatably attached to an attachment shaft 2 thereof. ing.

A driving rotary shaft 3 of a reciprocating movement device A which can reciprocate in parallel at a required interval with respect to the feeding bobbin mounting shaft 2 is provided.

The reciprocating device A includes a plurality of rotating wheels 5 having an inner ring surface 4 having an inner diameter larger than the diameter of the driving rotating shaft 3. It is penetrated, and the inner ring surface 4 of the adjacent rotating wheel 5 is set stepwise so that the portions where the inner ring surface 4 is pressed against the rotating shaft 3 are on opposite sides, and the rotating wheel 5 is attached to the rotating shaft 3. On the other hand, a gear 7 is fixed coaxially with a mounting shaft 6 for rotatably attaching the rotating wheel 5 to the body 8 so that the rotating wheel 5 can be interlocked at a supplementary angle which is a symmetrical angle.

[0011] To one of the rotating wheels 5 of the reciprocating device A, a distal end portion of a shaving rod 9 having a required length oriented in a direction substantially parallel to the rotating surface of the rotating wheel 5a is fixed. I have. Accordingly, the intersecting direction and the intersecting angle of the rotating wheel 5a to which the shaking rod 9 is fixed with respect to the driving rotary shaft 3 are changed in conjunction with the swing direction of the shaking rod 9 and the amplitude thereof.

An introduction portion 10 through which a wire w is inserted is provided at the tip of the shaking rod 9. The wire w introduced into the introduction portion 10 is led out from a lead-out portion 11 provided at a portion of the body 8 where the rotating wheel 5a fixed to the shaking bar is located.

The wire w led out from the lead-out section 11 of the container 8 passes through a guide bobbin 12 such as a pulley fixed to a required position at the end of the wire direction, and is taken up by a winding bobbin (not shown). ).

A pulley 13 is fixed to one end of the driving rotary shaft 3, and a motor 15 is connected to the pulley 13 via a belt 14. Therefore, the driving rotational force of the motor 15 is interlocked with the pulley 13, whereby the driving rotary shaft 3 is integrally rotated.

When the drive rotary shaft 3 rotates, the portions of the inner wheel surfaces 4 of the adjacent rotary wheels 5 that are in pressure contact with the drive rotary shaft 3 are set in steps so as to be opposite to each other. Since the wheels 5 are always interlocked with each other at symmetrical supplementary angle positions, each of the rotating wheels 5 moves in a direction determined by the direction of rotation of the driving rotary shaft 3. Therefore, the reciprocating device A integrated with the rotating wheel 5 moves in the same direction.

In this case, if the rotation speed of the driving rotary shaft 3 is fixed, the moving speed of the reciprocating device A increases as the intersection angle of the rotating wheel 5 with the driving rotary shaft 3 increases. As the intersection angle decreases, the moving speed decreases.

In the above configuration, prior to the start of operation, the pitch speed at which the wire w fed from the feeding bobbin 1 is released along the feeding bobbin surface and moves, and the movement of the reciprocating device A in the same direction. Initially, the speed is synchronized so that the wire w is wound on the winding bobbin from the introduction portion 10 of the rod 9 via the guide portion 12 of the body 8 through the guide wheel 12. .

The feeding operation of the wire w is started from the above-described initial setting state. Then, when the motor 15 is driven and the winding bobbin is rotated by driving the mounting rotary shaft (not shown) in use, tension is applied to the wire w and the wire w To the take-up bobbin while releasing.

FIG. 5 shows a state in which the feeding pitch speed of the wire w fed from the feeding bobbin 1 and the moving speed of the reciprocating device A in the same direction are synchronized in the feeding process of the wire w. As shown, the rod 9 is oriented in a predetermined direction by the action of the predetermined line tension. As a result, the crossing direction and the crossing angle of the rotating wheel 5 with respect to the driving rotating shaft 3 are constant.

In the above-described rewinding process, the wire w to be unwound is entangled or caught on the adjacent wire being wound, and the timing of the unwinding operation is shifted, so that the reciprocating device A When a delay occurs with respect to the moving speed, as shown in FIG. 6, the stable transmission state is broken, and the wire w generates more tension and the reciprocating device A Moves ahead.

In the state described above, the shaking rod 9 is swung in a direction corresponding to the change in the transmission line tension, and is displaced in a direction to maintain a balance. As a result, the crossing angle of the rotating wheel 5 with respect to the driving rotating shaft 3 is shifted in a direction orthogonal to the direction, and the moving speed of the reciprocating device A is reduced or stopped. This automatically adjusts the wire feeding direction from the wire feeding point that moves in parallel along the feeding bobbin surface so that it is always substantially perpendicular to the feeding bobbin. Automatically waits momentarily until recovery.

When the above-mentioned trouble is solved, the normal operation is restored to the initial state and the transmission of the wire w is automatically continued.

Thereafter, the same operation is performed to automatically follow the feeding direction of the wire fed to the feeding bobbin so as to always be perpendicular to the feeding surface and send the wire.

[0024]

[Effect of the invention]

 As is apparent from the above description, according to the present invention, the wire feeding point moving in parallel along the feeding bobbin surface and the reciprocating device for guiding and supporting the wire fed from the wire feeding point are parallel to each other. Since the wire can be moved synchronously, the wire feeding direction from the wire feeding point can always be substantially at right angles to the feeding bobbin, so that even when the wire is entangled or caught, it is quickly loosened and smoothly. The transmission line will be restored, so that the wire will not be distorted or damaged.

Further, the distance between the feeding bobbin and the sheave can be reduced, thereby contributing to downsizing of the structure and narrowing the installation space.
