Abstract
The present invention relates to a roto-linear mechanism for a glassware forming machine adapted to be connected to a funnel-holding arm, a shutter arm, an arm for a blowing head or a similar mechanism, to simultaneously perform an axial and radial movement to each of such arms from a first position to form glass articles to a second position outside the forming process thereof.

A method of operating a rotolinear mechanism for a glassware forming machine, the rotolinear mechanism comprising a first housing, a shaft located within the first housing, a cam follower means attached to an outer periphery of the shaft, a linear actuating means located within and associated with the shaft, a second housing connected to the first housing, and a cam profile associated with the second housing, the method comprising:
- connecting an operating arm to a lower end of the first shaft;
- coupling a drive means to the linear actuating means;
- and
- actuating the drive means to impart a rotational movement to the linear actuating means, causing the shaft to rotate and the operating arm to move in an angular direction with respect to a vertical centerline extending through the rotolinear mechanism, and to cause the shaft and operating arm to subsequently move in a downward vertical direction,
- wherein movement of the shaft in the downward vertical direction and causes the operating arm to be positioned adjacent to a mold for forming glassware.
A method of forming glassware using a glassware forming machine comprising:
- providing a rotolinear mechanism comprising a first housing, a shaft located within the first housing, a cam follower means attached to an outer periphery of the shaft, a linear actuating means located within and associated with the shaft, a second housing connected to the first housing, and a cam profile associated with the second housing;
- mounting the rotolinear mechanism above a glassware forming mold;
- connecting an operating arm to a lower end of the first shaft;
- coupling a drive means to the linear actuating means;
- and
- actuating the drive means to impart a rotational movement to the linear actuating means, causing the shaft to rotate and the operating arm to move in an angular direction with respect to a vertical centerline extending through the rotolinear mechanism, and to cause the shaft and operating arm to move in a downward vertical direction,
- wherein movement of the shaft in the downward vertical direction and causes the operating arm to be positioned adjacent to a mold of the glassware forming machine.
A rotolinear mechanism for a glassware forming machine adapted to be connected to an operating arm for simultaneously performing an axial and radial movement to the operating arm from a first position for forming articles to a second position outside of a forming mold for forming the articles, the rotolinear mechanism comprising:
- a first housing having an open lower end:
- a shaft located within the first housing and configured to internally slide in the first housing;
- a cam follower means attached to an outer periphery of the shaft,
- a linear actuating means located within and associated with the shaft, the linear actuating means having an upper end and a lower end;
- a drive means coupled to the upper end of the linear actuating means;
- a second housing connected to the first housing;
- and
- a cam profile associated with the second housing, the cam profile defining a path that includes a curved section and a vertical section, wherein
- actuation of the drive means imparts a rotational movement to the linear actuating means and causes the shaft to rotate by following such that the cam follower means follows along the path of the cam profile, causing the shaft to rotate and the operating arm to move in an angular direction with respect to a vertical centerline extending through the rotolinear mechanism, and to cause the shaft and operating arm to subsequently move in a downward vertical direction such that the operating arm is positioned adjacent to the forming mold for forming glassware.
