Abstract
A vacuum driven pill counter includes a counter housing with a pill discharge aperture formed therein. An integrally formed vacuum drum is rotatably positioned in the housing and the vacuum drum includes a front wall, a rear wall, and a perimeter wall. The front wall of the vacuum drum has a plurality of pill apertures formed therein. A vacuum source communicates with the housing such that the vacuum sources is capable of drawing a vacuum through the pill apertures formed in the vacuum drum and a torque source is operatively connected to the vacuum drum in order to rotate the vacuum drum. A pill shelf is positioned adjacent to the front wall of the vacuum drum and a pill separator removes pills retained on the pill apertures while a pill sensor detects pills which are removed by the pill separator and exit the discharge aperture. Additionally, the pill counter may include a pill feeder. The pill feeder has a frame with a top and bottom aperture and with the bottom aperture being positioned over an opening in the counter housing. A pill reservoir is positioned on the frame to allow pills to flow into the top aperture of the frame. A feed gate positioned within the frame is slidably movable between the top and bottom apertures.
