METHOD FOR PRODUCING MULTILAYER TABLETS WITH TABLET CORES, AND ROTARY PRESS FOR THE SAME

摘要

The invention relates to a method for producing multilayer tablets with the use of tablet cores, so-called core tablets, on a rotary press, comprising the steps feeding of tablet cores 21, transfer of the tablet cores with a core-inserting device 20 to a die opening 9 in a die plate (2), finishing of a tablet and removal or discharge of the tablet from the rotary press. The invention further relates to a rotary press for producing core tablets of this type. In order to achieve a more reliable process control in the production of core tablets, according to the invention the position of the tablet core 21 in the die or die opening 9 is registered with an optical system 10 after the transfer station 25. Since, with the optical system 10, the position of each tablet core or the actual fill state of each die opening 9 is registered behind the transfer station 25 and, where necessary, is further processed with an image-analyzing device and/or with a processor, a positioning adjustment and a separating out of bad tablets can be automated.
