Description

TECHNICAL FIELD The present invention relates to a winding machine, and more particularly to a winding machine suitable for use in manufacturing a coil.

“Prior Art” Conventionally, as a winding machine used for manufacturing a stator and a coil of a stepping motor, for example, a winding machine having a structure shown in FIG. 7 is known.

A winding machine 1 shown in this example has a movable rod 3 provided with a head 2 for sending out a linear body A (conductor wire) in a state where sliding along the length direction and rotation around an axis are allowed. The swing rod 4 is attached integrally to the base C, and the swing rod 4 orthogonal to the lengthwise direction is integrally provided at the intermediate portion of the movable rod 3, and the universal joint 5 is slidably attached to one end of the swing rod 4. The drive shaft 6 is rotatably attached to the base C along a direction orthogonal to the movable rod 3, and the drive shaft 6 is connected to the universal joint 5 at one end of the drive shaft. A connecting rod 7 that regulates a distance L ₁ between the rotation axis of the drive shaft 6 and the axis of the swing rod 4 is integrally provided with a bolt 8.

In the conventional winding machine 1 having such a configuration, the drive shaft 6 is rotated so that one end of the swing rod 4 is rotated along the rotation axis of the drive shaft 6 as shown by an arrow (a) in FIG. When the head 2 is also pivotally moved, the head 2 (specifically, the core of the motor) W that is arranged to oppose the head 2 has a linear condition (specifically, A conducting wire A to be wound around the core is wound around the core.

That is, with the turning movement of the swing rod 4 described above,
The movable rod 3 to which the swing rod 4 is attached is
As shown by arrows (b) and (c) in FIG. 7, the movable rod 3 is reciprocally moved by a predetermined distance in the longitudinal direction and is reciprocally rotated about the axis by a predetermined angle. The head 2 attached to the head is pivotally moved in substantially the same manner as the swing rod 4, as shown by the arrow (d) in FIG. Therefore, by installing the core W in the center of rotation of the head 2 and fixing the end of the linear body A pulled out from the head 2 to the core W, the linear body A is sequentially transferred from the head 2. It is wound around the outer circumference of the core material W while being pulled out.

"Problems to be Solved by the Invention" The present invention is intended to solve the following problems in the above-described conventional techniques.

That is, in order to tightly wind the linear body A around the core W, the lead-out position of the linear body A of the head 2 is relatively moved in the longitudinal direction of the core W so that the linear bodies A are aligned. Need to wrap.

However, in the winding machine 1, since the lead-out position of the linear body A in the head 2 is fixed, it is a problem that the range is limited when performing the above-described aligned winding.

On the other hand, in order to solve the above-mentioned problems, it has been attempted to move the core material W in the length direction with respect to the fixed head 2. In such a method, the core material W is Since the moving mechanism for moving the core material W must be provided together with the aligning mechanism with the head 2, it is not an effective solution because it complicates the entire apparatus. Especially, in the stator of the stepping motor,
In the case of winding the wires, since the core as the core material W is radially provided, the stator is intermittently rotated to sequentially align each core with the head 2 and Since the winding must be performed, the above-mentioned problems become more remarkable.

"Means for Solving Problems" The present invention is to provide a winding machine capable of effectively solving the above-mentioned problems in the prior art. In the winding machine, the winding machine is slidable on a base. And a rotatably mounted main rod, a head provided at one end of the main rod for radiating the conducting wire, the head being movably provided in the radial direction around the main rod, and the base. A drive shaft provided along the direction orthogonal to the main rod, and converting the rotation of the drive shaft into a reciprocating motion in the length direction of the main rod and a reciprocating motion around the shaft, thereby causing the nozzle to rotate around the core. And a traverse mechanism that adjusts the winding distance of the conducting wire by adjusting the protrusion amount of the nozzle, and the motion converting mechanism is configured to move the drive shaft. The traverse mechanism includes a connecting rod that swivels as a center, and a swinging rod that has one end connected to the tip of the connecting rod via a universal joint and the other end fixed to the main rod. A sub rod that is coaxially and frictionally fitted so as to be relatively rotatable, and is provided between one end of the sub rod and the nozzle, and converts relative rotation of the sub rod and the main rod into movement of the nozzle in the direction. And a cam member that engages with the other end of the sub rod to restrict the rotation of the sub rod within a predetermined range.

[Operation] According to the above configuration, as the drive shaft rotates, the axial direction and the axial motion are transmitted from the swing rod connected to the connecting rod via the universal joint to the main rod. Further, by restricting the rotation of the sub rod within a predetermined range by the cam, the sub rod rotates relative to the main rod in a region where the rotation of the sub rod is restricted, and this rotation is mediated by the rack and pinion mechanism. Is converted into a reciprocating motion of the nozzle, and the dynamic drawing position from the nozzle moves in the length direction of the core.

The engaging pin 31 protruding in the radial direction is inserted into the. By rotating the cam cylinder 30, the cam member 19 engages the engagement pin 31 with the side wall surface of the opening 30a to restrain the rotation of the sub rod 17.

Next, the operation of the winding machine 10 of the present embodiment configured as described above will be described below.

First, as shown in FIG.
The core material W (stator X) which is inserted into the (sub rod 17) and the head 13 and is drawn out through the nozzle 12 and has one end facing the vicinity of the nozzle 12 (stator X
Attached to the core Y).

Next, the drive shaft 14 is rotationally driven to move the universal joint 26 attached to the connecting rod 27 and the swing rod 22 fitted in the universal joint 26, as shown by the arrow A in FIG.
Swivel around 14 axes of rotation. By this,
The main rod 11 is reciprocated along its length as shown by arrow B in FIG. 1, and is reciprocated about the axis at a predetermined rotation angle (θ) as shown by arrow C in FIG. By doing so, the nozzle 12 of the head 13 can be swiveled around the core Y as shown by the arrow D in FIG. When the head 13 is pivotally moved in this way, one end of the linear body A is attached to the core Y, so that the linear body A is sequentially pulled out from the nozzle 12 while the outer periphery of the core Y is being pulled out. Wrapped around.
Further, in this embodiment, since the two nozzles 12 are provided, the linear body A can be wound around the two cores Y at the same time.

On the other hand, as described above, during the winding process, the nozzle
As shown in FIG. 5, 12 is swung at the same angle as the turning angle θ of the mail rod 11, and the sub rod 17 is frictionally fitted to the main rod 11 and is turned integrally by the friction force. Therefore, the engagement pin 31 provided on the sub rod 17 is also swung at the same angle θ as the nozzle 12.

Here, when the number of turns of the nozzle 12, that is, when the winding of the linear body A is made to a desired amount, the cam cylinder 30 is rotated in a predetermined direction by a predetermined angle. For example, when the cam barrel 30 is rotated from the position shown in FIG. 5 by an angle β as shown in FIG. 6,
The main rod 11 continues its rotation, but the sub rod 17
Is restrained from rotating by engaging the engaging pin 31 with the side wall of the opening 30a of the cam cylinder 30 in one of the swinging directions thereof, whereby the sub rod 17 is protected against the frictional force. On the contrary, the cam barrel 30 is rotated relative to the main rod 11 by the rotation angle β. After such relative rotation, the engagement between the engaging pin 31 and the side wall of the opening 30a is released, so that the sub rod 17 is again caused by frictional force together with the main rod 11 as shown in FIG. As shown by the chain line in FIG. On the other hand, when the main rod 11 and the sub rod 17 are relatively rotated in this manner, the drive gear 28 and the canter gear 29 of the gear group 18 are relatively rotated as indicated by the arrows in FIGS. 3 and 4. At the same time, the counter gear 29 and the rack 24 are moved relative to each other, and as a result, the nozzle 12 is moved in its longitudinal direction, in this embodiment, into the head 13 as shown by the arrow E in FIGS. 2 and 3. It can be moved backwards.

Therefore, by controlling the rotation angle of the cam barrel 30, as shown in FIG. 2, the drawing position of the linear body A of the nozzle 12 is sequentially moved in the length direction of the core Y. , The linear body A is aligned and wound.

It should be noted that the shapes, sizes, combinations and the like of the respective constituent members shown in the above embodiment are merely examples, and can be variously changed based on design requirements and the like.
