ABSTRACT:
Appratus for automatically removing stuck and down ware from an automatic glassware forming machine conveyor produces a first signal for each item of normal ware, stuck ware and down ware which is conveyed past an inspection location. Each of the first signals has a duration corresponding to the time required for passage of the corresponding item past the inspection location. In order to prevent the generation of spurious first signals, two spaced radiant energy beams are sensed which are directed transversely across the transport path of the wares and which are in coplanar alignment perpendicular to the transport path of the wares. A first one of the beams is aligned with the bases of upright wares and the other of the beams is aligned above the first beam. The first signal is produced if either of the beams is interrupted. The apparatus also produces a second signal simultaneously with the production of each of the first signals, the second signals having a predetermined duration corresponding to the time required for a normal upright and spaced item of ware to be conveyed past the inspection location. The generation of a reject signal during the duration of each of the second signals is inhibited and a reject signal is generated if a first signal is present after the termination of the corresponding second signal, which actuates a signal responsive automatic ware removal mechanism.
