Abstract
A device for the shaping of glass bodies, in particular of pharmaceutical vials, comprises a clamping chuck for holding a glass body, a rotary drive for driving the clamping chuck rotatingly, further at least one heat source for heating a glass body held within the clamping chuck, and further a controller which is coupled to the rotary drive so that the clamping chuck can be driven at variable rotational speed.
Claims13
A device for the forming of glass bodies, comprising a plurality of processing stations, each processing station comprising:
- a clamping chuck for receiving a glass body;
- a rotary drive for driving said clamping chuck rotatingly at a rotational speed;
- a controller being coupled to said rotary drive allowing to control said rotational speed of said rotary drive continuously between a minimum value and a maximum value so that said rotational speed of said rotary drive of said plurality of processing stations are controlled independently from each other;
- and
- at least one handling device configured to remove the glass body from one of said plurality of processing stations that performs a first processing step on the glass body and to transfer the glass body to a different one of said plurality of processing stations that performs a different processing step on the glass body,
- wherein at least one of said plurality of processing stations further comprises at least one heat source for heating the glass body.

A device for the forming of glass bodies, comprising:
- a clamping chuck for receiving a glass body;
- a rotary drive for driving said clamping chuck rotatingly at a rotational speed;
- a controller being coupled to said rotary drive allowing to control said rotational speed of said rotary drive continuously between a minimum value and a maximum value;
- a shaping body being arranged to advance against the glass body in a radial direction to close a bottom of the glass body;
- and
- at least one heat source for selectively heating the glass body received within said clamping chuck,
- wherein said clamping chuck and said heat source are configured for being positioned in an axial direction with respect to each other.

A device for the forming of a glass body, comprising:
- a plurality of processing stations, each processing station comprising a clamping chuck for receiving the glass body and a rotary drive for driving said clamping chuck rotatingly at a rotational speed;
- a controller coupled to said rotary drive of all of said plurality of processing stations, said controller being configured to control the rotational speed of each rotary drive continuously between a minimum value and a maximum value;
- and
- at least one handling device configured to remove the glass body from one of said plurality of processing stations and to transfer the glass body to a different one of said plurality of processing stations,
- wherein said plurality of processing stations comprises at least two processing stations that further comprise at least one heat source for heating the glass body,
- wherein the rotational speed of said rotary drive of said at least two processing stations is controlled independently from each other, and
- wherein said controller controls said clamping chucks to a standstill and said at least one handling device is configured to remove and transfer the glass body between said plurality of processing stations only when said clamping chucks are at said standstill.

A device for the forming of glass bodies, comprising:
- a clamping chuck for receiving a glass body;
- a rotary drive for driving said clamping chuck rotatingly at a rotational speed;
- a heat source for selectively heating the glass body received within said clamping chuck;
- a shaping body being arranged to advance against the glass body in a radial direction to from a closed bottom on the glass body and to retract from the glass body after closing said closed bottom;
- and
- a controller being coupled to said rotary drive and said shaping body, said controller being configured to increase said rotational speed of said rotary drive after retraction of said shaping body from said closed bottom so that said closed is a flat bottom with even material thickness.
