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.
Claims14
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, the shaft having a hollow passage formed from a top of the shaft to about half of a total length of the shaft, a cam follower means attached to an outer periphery of the shaft and located below an open lower end of the first housing, a linear actuating means located within and associated with the shaft, the linear actuating means located within and ending in the hollow passage of the shaft at a location above the cam follower means, 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 shaft, wherein the lower end of the shaft extends beyond the open lower end of the first housing;
- 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 a first 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 causes the operating arm to be positioned adjacent to a mold for forming glassware enabling the operating arm and mold to cooperate to form the 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, the shaft having a hollow passage formed from a top of the shaft to about half of a total length of the shaft, a cam follower means attached to an outer periphery of the shaft and located below an open lower end of the first housing, a linear actuating means located within and associated with the shaft, the linear actuating means located within and ending in the hollow passage of the shaft at a location above the cam follower means, 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 shaft, wherein the lower end of the shaft extends beyond the open lower end of the first housing;
- 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 a first 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 causes the operating arm to be positioned adjacent to a mold of the glassware forming machine enabling the operating arm and mold to cooperate to form the glassware.
