| 20090099687 | Method and apparatus for continuous motion tipping of tip-on products onto continuously moving base products - A method and apparatus to facilitate accurately matching and placing non-uniformly spaced tip-on products from a friction feeder onto non-uniformly spaced base products that are traveling on a base conveyor while both the friction feeder and the base conveyor are continuously moving. Using encoders on the conveyor drive motors to track conveyor position and electronic sensors to detect the arrival on tip-on products and base products at predetermined points along their respective conveyors, a programmed microcontroller implements an algorithm for adjusting the speed of the sheet feeder's discharge conveyor so that the tip-on product and base product arrive at a matchpoint simultaneously. | 04-16-2009 |
