© Server system for rubberized sheets.
00
© A system and apparatus for accurately delivering
rubberized sheets from a supply, roll of stock material containing an intervening liner to an assembly
station for subsequent assembling into an air spring
or similar article of manufacture by eliminating the
heretofore formation of a "free loop" therein. The
supply roll and a liner take-up reel are rotatably
mounted on a carriage transversely movable with
respect to the longitudinal motion of the stock material. A hugger device has a plurality of timing belts
which frictionally engage the liner at the take-up reel
and winds the liner onto the reel at a constant linear
speed regardless of the diameter of the reel and
collected liner to move the rubberized sheet at a
controlled rate toward the assembly station. The
motion profile of the timing belts is controlled by a
servo drive motor and the belts engage an arcuate
portion of the circumference of the take-up reel to
provide positive frictional drive engagement therewith. The carriage is moved along a pair of tracks by
a ballscrew mechanism for bringing the cartridges of
stock material and take-up reel into position with the
timing belts and assembly station. An optical edge
detection device and encoder, in conjunction with a
motion controller, accurately control and regulate the
system.
