Abstract
In an apparatus (1) for the severing of gobs from one or more strands (2;3) of molten glass, the severing of each gob is effected by a shear blade pair (5;6). A shear blade (7,8;9,10) of each shear blade pair is arranged on an associated, pivotably mounted shear arm (11;12). The two shear arms (11;12) are coaxially and freely pivotably mounted relative to each other on a common column (13). Each shear arm is pivotably drivable synchronously in relation to the other by its own separate drive means (24;25).
Claims18
Apparatus for the severing of glass gobs from one or more strands of molten glass, each strand having a longitudinal axis, said apparatus comprising:
- a pair of shear blades for effecting the severing of each gob;
- a pair of shear arms, each shear blade of said pair of blades arranged on a respective shear arm of said pair of shear arms;
- a common column on which said pair of shear arms are coaxially and freely pivotally mounted, said common column having a longitudinal axis;
- and
- a powered electric servodrive for pivotally driving said pair of shear arms in synchronism with each other, wherein each said shear arm has a separate said electric servodrive associated therewith.
An apparatus for severing glass gobs from at least one strand of molten glass, each strand having a longitudinal axis, said apparatus comprising:
- first and second shear blades;
- first and second shear arms, said first blade arranged on said first shear arm, said second blade arranged on said second shear arm;
- a common column on which said first and second shear arms are coaxially and pivotally mounted to be pivotally moveable about said column, said common column having a longitudinal axis;
- and
- a separate first and second electric servodrive coupled to each said shear arm to pivotally move said first and second shear arms, respectively, in synchronism with each other to sever the glass gobs.
An apparatus for moving at least one pair of cooperating shear blades to sever glass gobs from at least one strand of molten glass, each strand having a longitudinal axis, said apparatus comprising:
- first and second shear arms, each said shear arm designed to hold at least one shear blade;
- a common column on which said first and second shear arms are coaxially and pivotally mounted to be pivotally moved about said column, said common column having a longitudinal axis;
- and
- first and second drives associated with said first and second shear arms respectively to pivotally move said first and second shear arms in synchronism with each other, each said drive comprising an electric servodrive and a coupling rod, said rod having one end coupled to be moved by its associated said servodrive and another end coupled to move its associated said shear arm.
