ABSTRACT:
A device is provided for testing the integrity of each container in a conveyed sequence of containers by individually applying pressure internally of each, sensing that pressure and generating a signal having a magnitude corresponding to the value of that pressure, comparing that signal magnitude to a selected threshold signal value, providing an output control signal indicative of the achievement of that signal magnitude and setting an enablement device in one of two states corresponding to the presence and absence, respectively, of that output control signal. One of those states corresponds to an unacceptable container condition and the other to an acceptable container condition. If the unacceptable container condition or reject state exists, a reject cycle is enabled over at least an enabling duration sufficient to clear the container or broken portion thereof from the position it occupies in the sequence. The reject apparatus enabled during the reject cycle is constrained to apply a reject force such as a jet of air over the space occupied by the unacceptable container as well as space upstream therefrom within the extent of the reject cycle to clear from the conveyor all debris associated with the unacceptable container. A counter is provided in several embodiments for determining the number of acceptable containers in a give sequence. A mechanical reject device extends and retracts within the selected enabling duration while the air is enabled for the duration of the reject cycle to purge the conveyor surface.
