ABSTRACT:
A slat-type article counting machine includes slats provided with cavities which carry the articles, an exact count of which are designed to be discharged into bottles or containers. Each cavity defines a hole which penetrates the entire slat depth. Two pairs of scanners are mounted to the machine, one for detecting missing articles from cavities and the other for detecting articles wedged or blocked therein. A pair of scanners comprises sensors which include an array board having multiple light-emitting diodes which project light beams through the holes provided in the cavities to thereby strike photoelectric cells mounted to another array board, which photoelectric cells generate signals which cooperate with sensing and logic circuits for effecting visual and audible means for indicating miscounts due to empty or blocked cavities. A wide range of auxiliary operations and functions may additionally be initiated by the signals.
