Description

ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an improvement of a winding machine which is suitable for winding a stator of a motor.
BACKGROUND OF THE INVENTION
With regard to a winding machine for a stator of an inner rotor type motor, a servo mechanism of a winding machine which moves a nozzle in triaxial directions is disclosed in Japanese Patent Laid-Open Publication No. Hei 10-271774 published by the Japanese Patent Office in 1999. The servo mechanism moves in three dimensional directions a nozzle which feeds a wire for winding and precisely controls a position of a wire feeding end of the nozzle, thereby enabling well-ordered winding saving a high space factor.
The traxial servo mechanism is constituted such that each lengthwise, lateral, and vertical movement mechanism is piled one after another. Therefore, a movement mechanism situated at the lowest position has to move other upper movement mechanisms when it moves, whereby its movement becomes slow.
For example, the lengthwise movement mechanism supports the lateral movement mechanism in such a manner that the lateral movement mechanism can move lengthwise, and the lateral movement mechanism supports the vertical movement mechanism in such a manner that the vertical movement mechanism can move lateral. Further, the vertical movement mechanism supports a nozzle section in such a manner that the nozzle section can move vertically, whereby the nozzle section can move three dimensional directions. In this case, however, the lengthwise movement mechanism has to move the lateral movement mechanism and the vertical movement mechanism together with the nozzle section, and the lateral movement mechanism has to move the vertical movement mechanism together with the nozzle section. Therefore, a lengthwise movement of the nozzle caused by the lengthwise movement mechanism and a lateral movement of the nozzle caused by the lateral movement mechanism cannot be high-speed.
It therefore an object of the present invention to enable high precision and high speed winding of a winding machine.
SUMMARY OF THE INVENTION
In order to achieve the above object, this invention provides a winding machine which winds a winding section of a work in such a manner that a nozzle for feeding wire rods goes around the winding section, the winding machine comprising: a nozzle section which has a nozzle for guiding wire rods; at least three movement mechanisms for moving the nozzle section in three dimensional directions; and a connecting section for directly connecting two movement mechanisms out of the at least three movement mechanisms with the nozzle section, respectively, in such a manner that any one of the two movement mechanisms does not restrict movement of the nozzle section in a direction of movement of the other movement mechanism, wherein the two movement mechanisms are movably supported by the remaining movement mechanism.
A winding machine which winds a wire around a winding section of a work in such a manner that a nozzle for feeding wire rods goes around the winding section, the winding machine comprising; first and second movement mechanisms for moving the nozzle; a first connecting section for connecting the first movement mechanism and the nozzle in such a manner that relative displacement of the first movement mechanism and the nozzle in a first direction is allowed; and a second connecting section for connecting the second movement mechanism and the nozzle in such a manner that relative displacement of the second movement mechanism and the nozzle in a second direction being at right angles to the first direction is allowed.
The winding machine further comprises a third movement mechanism for moving the first movement mechanism and the second movement mechanism in a third direction which is at right angles to the first direction and the second direction.
The winding section has a horizontal center axis, and it is set such that the first direction and the second direction are at right angles to the horizontal center axis and the third direction is parallel to the horizontal center axis.
