Abstract
An I.S. machine has a blow station where a parison is blown into a bottle. The parison is blown with a blow head at the “on” position on the blow mold and following the blowing of the parison, the blow head is lifted away from the blow mold. The spacing between the blow head and the mold is defined by a Pressure Profile which is responsive to the sensed pressure within the mold.
Claims20
A method of introducing cooling air into glass containers at a blow station of an I.S. Machine, comprising:
- displacing the position of a blow head between a first on blow mold position and a second off blow mold position;
- displacing a cooling tube operatively associated with the blow head between a first up position and a second down position independently of the displacement of the blow head;
- providing a source of pressurized air to the cooling tube for both blowing a parison into a glass container and for cooling a glass container subsequent to it having been blown;
- sensing the pressure within the blow head;
- and
- controlling the position of the blow head according to a selected pressure profile as a function of pressure sensed within the blow head by displacing the blow head to space it from the blow mold to maintain the pressure sensed within the blowhead at the selected pressure profile over time.
A method of introducing cooling air into glass containers at a blow station of an I.S. Machine, comprising:
- varying the position of a blow head between a first on blow mold position and a second off blow mold position;
- displacing a cooling tube operatively associated with the blow head between a first up position and a second down position;
- providing a source of pressurized air to the cooling tube for both blowing a parison into a glass container and for cooling a glass container subsequent to it having been blown;
- sensing the pressure within the blow head;
- and
- controlling the position of the blow head and the position of the cooling tube as a function of a control algorithm.
