摘要:
An end effector apparatus for attachment to an industrial robot for transferring prepressed windshields to an autoclave tub. Vacuum cups engage and secure the windshield to the end effector for transfer of the windshield from an upender conveyor to the tub. A combination spacer clip sensing device and spacer clip retaining device senses the presence of a spacer clip on the top edge of the windshield and holds the clip in place during transfer.
摘要:
Intersecting first and second scores in a glass sheet are simultaneously opened by imposing deeper first scores in the glass sheet than second scores. A bending moment force applied to a second score opens the second score and the resulting shock from opening the second score opens portions of the intersecting first scores.
摘要:
A spacing conveyor section includes a plurality of shafts each having a spring mounted thereon and a plurality of spaced donut rolls mounted on the spring. Glass sections having their leading edges transverse to the sheet movement path and generally aligned with one another are advanced onto the spacing rolls. Thereafter the springs are stretched to increase the distance between sides of adjacent sections. The sections are then advanced along the spacing conveyor section into downstream work positions.
摘要:
A cutting fluid is disclosed comprising one or more halogenated hydrocarbons dissolved in one or more paraffin, naphtha, or aromatic solvents. Use of the cutting fluid produces a glass edge with increased edge strength compared with a cut edge produced by dry scoring. The cutting fluid is completely evaporative, leaving no residue, thus eliminating the need for washing. Further, use of the cutting fluid extends the useful life of the cutting tool. Blends are formulated to meet specific evaporation rates required by variations in wareroom equipment and practices.
摘要:
A glass sheet is cut while at a temperature at about its annealing point temperature by scoring the glass sheet along a line of cut and imparting a bending moment to the glass along the scored line to open the glass. The glass sheet remains at its elevated temperature throughout the cutting operation to reduce or eliminate additional heating required for subsequent processing.
摘要:
A glass ribbon moves downstream under a pair of scoring wheels to score the bulb edges of the ribbon and thereafter past a cross scorer to laterally score the ribbon. As the ribbon moves further downstream the scores at the bulb edge move under (1) a plurality of hot airstreams which propagate the fissure depth of the score and (2) under a cold airstream to concentrate the stress field about the score line to prevent premature severing of the bulb edges due to mechanical vibrations generated during subsequent opening of the lateral score.
