摘要
Jar caps of the vacuum-indicating, flip panel type are classified and sorted according to panel flexure characteristics. Two different positions of each panel are induced by successively establishing high- and low-pressure differentials across the panel. In each case the panel position is compared to the norm therefor. A memory device information retrieval element is correspondingly conditioned to signalize either deviance or freedom therefrom in respect of both induced positions. The memory device is then investigated and the cap is classified accordingly. Apparatus is provided for automatically classifying and sorting caps. The caps are serially fed to a carrier which traverses a series of cams. The cams actuate switches controlling vacuum, sensing, and memory device components. The memory device retrieval element controls an ejector according to the mode prevailing. The ejector discharges caps from the carrier at different locations according to whether a particular cap is rejected or accepted with respect to both comparisons.
