Abstract

A drive mechanism for driving a plurality of components arranged in a ring shape to move back and forth in a radial direction, the drive mechanism is disposed in an annular disk, each component has a shoulder, the drive mechanism includes: a circular body coaxial disposed on the annular disk; a drive wheel rotatably disposed coaxially with the circular body; a cam ring disposed coaxially with the drive wheel, having a diameter smaller than that of the drive wheel, and including at least one cam; a plurality of pushing elements provided for contacting the shoulder of the respective components and each having a driven portion abutted against the cam ring, so that the pushing elements are moved toward or away from the axis, and the pushing elements contact the shoulders to drive the components to move in the radial direction or in the direction of the axis.

Claims9

Dependent claims

A drive mechanism for driving a plurality of strip members or transfer members arranged in a ring shape to move back and forth in a radial direction, the drive mechanism being disposed in an annular disk having a plurality of guide channels for accommodating the strip members or transfer members, each of the strip members or transfer members having a shoulder, the drive mechanism comprising:

a circular body coaxial with and disposed on the annular disk;
a drive wheel rotatably disposed coaxially with the circular body;
a cam ring disposed coaxially with the drive wheel, having a diameter smaller than a diameter of the drive wheel, and including at least one cam;
a plurality of pushing elements provided for contacting the shoulders of the respective strip members or transfer members, each of the pushing elements being substantially in the form of a circle segment and able to move towards or away from an axis around which the annular disk, the circular body, the drive wheel and the cam ring are coaxially arranged;
wherein each of the pushing elements has a driven portion abutted against the at least one cam of the cam ring, so that the pushing elements are driven to move toward or away from the axis, the pushing elements are used to contact the shoulders to drive the strip members or transfer members that are arranged in a ring shape to move in the radial direction or in the direction of the axis.

A drive mechanism for driving a plurality of strip members or transfer members which are in the longitudinal form arranged in a ring shape to move back and forth in a radial direction, the drive mechanism being disposed in an annular disk having a plurality of guide channels for accommodating the strip members or transfer members, each of the strip members or transfer members having a shoulder, the drive mechanism comprising:

a circular body coaxial with and disposed on the annular disk;
a drive wheel rotatably disposed coaxially with the circular body;
a second cam ring disposed coaxially with the drive wheel, and having a diameter smaller than a diameter of the drive wheel;
a plurality of drive members provided for contacting the shoulder of the respective strip members or transfer members, each of the drive members being substantially in the form of a circle segment and able to move towards or away from an axis around which the annular disk, the circular body, the drive wheel and the second cam ring are coaxially arranged;
a plurality of levers arranged corresponding to the drive members, and each have one end pivotally connected to the second cam ring and another end connected to the drive wheel in a controllable manner, and a portion between the two ends of each of the levers is abutted against a corresponding one of the drive members.
characterized in that:
the drive members are driven to move toward or away from the axis, and the drive members are used to contact the shoulders to drive the strip members or transfer members to move in the radial direction or in the direction of the axis.
