ABSTRACT:
Methods and apparatus for counting tablets and feeding a predetermined number of tablets to a bottle are disclosed. The present invention creates a fluidized bed of tablets above a plurality of slat bars, each of which comprises a plurality of cavities having a vacuum port connected to a source of negative pressure. The vacuum draws individual tablets down from the fluidized bed and into the cavities in the slat bar, thereby ensuring efficient and complete filling of each cavity with a tablet. Upon exit from the fluidized bed, the vacuum flow is disconnected and, in certain embodiments, a positive airflow may be flowed through the vacuum ports to eject the tablets into means for feeding the tablets into bottles.
