Device for producing core tablets and coated core tablets (double-core or multi-core tablet)

摘要

Device for producing core tablets with a rotary tablet press, which has a revolving rotor (11) with a die plate (10), wherein the die plate is provided with a plurality of die openings (12) distributed over its circumference, and with at least one core depositing device with a rotatably drivable core distributor disk (15) which is provided at its circumference with a plurality of core receiving units (16) whose trajectory (26) overlaps with a trajectory (27) of the die openings (12) at at least one transfer point (28) The core receiving units (16) each have at least two receiving pockets (22) for receiving core inserts (23) whose arrangement and distance from each other within the respective core receiving unit (16) is such that the in the receiving pockets (22) of a core receiving unit (16) recorded core depositors (23) in the overlapping area (28) both movement paths (26, 27) can be transferred jointly into a single die opening (12), wherein the receiving pockets (22) are designed as tooth spaces (34) formed by a sawtooth-like configuration of the outer periphery (33) of the core distribution disc (15) and the receiving pockets (22) tooth spaces (34) forming a core receiving unit (16) have a tooth face (35) which is approximately concave in the direction of rotation (20) of the core distributor disc (15) for substantially positive engagement of a core insert (23) and an outer circumference lying in the direction of rotation (33) of the core distribution disc (15) under a first curvature (37) radially inwardly drawn and under opposite, second curvature (38) in the tooth surface (35) transition tooth back (36), characterized in that in the direction of rotation (20 ) the Kernverteilerscheibe (15) respectively arranged at the front tooth gaps (34 a) within a core receiving unit (16) in Umfa Longitudinal tooth back (36 a) than the direction in the direction of rotation (20) behind it (s) tooth gap (s) (34 b) have.
