A system for rejection of tablets produced in a rotary tablet press comprises pan ejection nozzle for sorting out defective tablets. The ejection nozzle is supplied with compressed gas through a supply line having an inlet end for connection with a source of compressed gas and an outlet end communicating with the ejection nozzle. The supply line is provided with a control valve controlled by a control unit in order to open the supply line when a defective tablet has been detected by the control unit. Furthermore, the supply line is provided with a sensor arranged between the control valve and the inlet end of the supply line and adapted to detect a variable indicative of a gas flow through the control valve in order for the control unit to generate an error signal in the case of malfunction of the control valve.

System for rejection of tablets produced in a rotary tablet press and a method of rejection of tablets

A rotary tablet press comprises a rotary system constituted by a turret and a drive shaft arranged in a housing for rotation of the turret. The turret includes a die table and a number of punches are guided in the turret. The turret is connectable to the drive shaft by a coupling including a first coupling part and a second coupling part which are interconnectable by clamping elements engageable between the coupling parts by at least one pneumatic actuator situated in the rotary system.

Rotary tablet press

The rotary tablet press comprises a housing, in which a compression unit ( ) is detachably mounted. The compression unit ( ) comprises a die table ( ) with punches ( ), a feeding device for the supply of material to be compressed into the dies ( ), and a tablet discharge device for removal of compressed material in the form of tablets. The compression unit ( ) encloses each die opening and its corresponding first punch end ( ) in a chamber, the feeding device and the tablet discharge device are enclosed, the feeding device communicates with an inlet for detachable connection with an external supply channel, and the tablet discharge device communicates with an outlet.
