摘要:
A method of manufacturing of strengthened glass containers, and more particularly a method of thermally strengthening glass containers in a glass container manufacturing line at a location intermediate the hot end and the cold end. Glass containers formed at an I. S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers are subjected to a unique rapid thermal strengthening cooling process in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers.
摘要:
A pneumatic machine control unit for an I.S. machine having at least one machine section for processing a gob of molten glass into a selected bottle. The section is supplied by a plurality of pneumatic lines at different pressures. A pneumatic supply input line supplies a manifold which is connected to a plurality of output lines. An electronically settable pressure regulating device is situated in each output line and a control is provided for setting the electronically settable pressure regulating devices either in response to operator inputs or from retrieved pressures from a database.
摘要:
A shear mechanism for shearing discrete gobs from at least one runner of molten glass has a shear assembly which is displacable back and forth along a pair of guide rails. The assembly has at least one shear supported on an arm which has a bearing at one side which is operatively associated with one of the guide rails. The support bearing has a lower bearing surface which engages the bottom of the guide rail and an upper bearing surface which supports the top surface and the lower bearing surface can be displaced away from the guide rail by operating a release which is located on the top of the bearing.

A blow head is displaced to the “on” position where its lower portion engages the top of a blow mold. Final blow begins and before final blow is completed, the blow head is raised a selected distance and final blow is exhausted between the O.D. of the formed finish and the upwardly defined annular recess in the lower portion of the blow head. The annular recess is concavely curved to direct exhaust air at the finish to cool the finish.

A parison is blown in the blow mold of an I.S. machine and a control determines the time of the event by defining a local minimum in the pressure vs. time plot.
摘要:
A control system for controlling the operation of the shears of a glassware forming machine. The control system incorporates sensors which produce signals representative of predetermined shear positions in each shear cycle, and in particular, makes use of the correlation between the duration of a Zero Crossover Signal and the point of maximum overlap of the shears. The system adjusts the time of deactuation of a fluidic drive assembly, and therefore, the overlap displacement, if the termination of the Zero Crossover pulse falls outside a defined "deadband". The Zero Crossover signal may also be monitored to provide alarm signals or shut the system down.

The displacement of the plungers in a multi-gob individual section glass forming machine is monitored so that the location of the plungers, when each mold cavity has completely filled (parison formation point), can be determined. The desired location for the parison formation point for each plunger can be selectively chosen and the occurrence of these parison formation points can be synchronized to achieve fuller control over the parison formation process.
摘要:
A blow mold assembly for an I.S. machine for blowing a parison of glass and cooling the blown parison into a formed bottle which can be removed from the blow mold. A blow head is lowered onto a blow mold and final air is applied. A predetermined time after the blow head engages the top surface of the blow mold the blow head is lifted a selected vertical distance above the top surface of the blow mold to an exhaust position allowing cooling air to escape from the blow mold. The selected vertical distance is selected so that at least a minimum pressure will continue within the formed bottle. The blow head is maintain at the exhaust position for a predetermined time and then retracted. The selected vertical distance and the predetermined time can be set as desired.
摘要:
A takeout mechanism for an I.S. machine grips a formed bottle at the blow station and carries the bottle to a first position spaced above a deadplate. The bottle is held at this position for a period of time and then is lowered to a position proximate the deadplate whereupon it is released.
