Method and apparatus for sorting tablets at a rotary press for making tablets

An apparatus for sorting tablets at a rotary press for making tablets, comprising:

• a wiper is provided associated with a die plate of a rotor of said rotary press,
• said wiper directing the tablets ejected from die bores of the die plate from the upper side of the die plate into a good-channel, and
• wherein, in the rotary direction of the rotor, a bad-channel is provided in front of the good-channel,
• said bad-channel being provided with an associated nozzle,
• the air blast of said nozzle being directed into the bad-channel, and
• wherein further a monitoring device at the rotary press monitors at least one property of the tablet and generates a bad-signal, if the desired property of a tablet is not fulfilled,
• and a control unit for the nozzle activates the nozzle in accordance with the bad-signal,
• characterized in that a first nozzle (2), located at the entrance of the bad channel, and is provided in the direction of the air stream in front of the nozzle (5), generating an air stream directed into the bad-channel (7), and
• further wherein the good-tab1ets from the die plate are directed into a good-channel by the wiper, and in that a second air stream is directed into the good-channe1, which accelerates the good-tablets into the good-channel.
