Tablet counting machine is used in pharmaceutical industry. Tablets are placed in the hopper. Crossing through the initially adjusted vibrating feed in plate, tablets in the hopper will continuously do the forward vibration along the vibrating rail until they fall down through the frontal photoelectric inspecting channel. As a result, photo electric sensor is touched and begins to count tablets. As soon as medical grains reach the scheduled quantity, plc will give a signal to electro-pneumatic valve so as to close the feed opening. Then, counted grains will fall into the outgoing bottles and the course of tablet counting is finished. As long as any inaccurate counting happens, this machine can pick out the bottle automatically, ensuring its 100% precision for every bottle.
