  • a solution for setting the punches (221; 321) in motion along this circular path is to use a drive plate (222; 322) mounted in rotation with respect to the frame 1, integral and coaxial with respect to the rotary plate (21 ; 31).
  • a drive plate (222; 322) is for example provided with through openings arranged at its periphery, these through openings being intended to receive the punches (221; 321) of the set of punches (22; 32).
  • the punches (221; 321) are therefore driven in rotation by the drive plate (222; 322), in synchronization with the corresponding die (210; 310), the punches (221; 321) also being able to slide in the openings provided at the periphery of the drive plate (222; 322) so that the compaction ends of the punches (221; 321) can be inserted into the corresponding die (210; 310).

  • the compaction phase during which the punch (221; 321) is moved so as to be inserted into the corresponding die (210; 310) to reduce the volume confinement, until a final compaction volume (Vf) is reached where a final compressive force can be applied for example.
  • Vf final compaction volume
  • the compaction volume corresponds to the desired final volume for the tablet.
  • the compaction volume is slightly less than the volume end sought for the tablet; this is the case, for example, when the compounds compressed in tablet form still exhibit a certain elasticity.

  • the compaction can be finalized by applying a final compressive force to the powder mixture confined in the die, and there can be provided to do this a compaction roller 224 arranged in the cam track of the control cam.

  • the backpressure assembly (23; 33) arranged on the side of the turntable (21; 31) opposite to the side where the punches (221; 321) are arranged has the function of closing the dies (210; 310) when the phase of compaction begins and in particular when the punches (221; 321) of the set of punches (22; 32) enter the respective dies (210; 310).
  • the backpressure assembly is therefore (23; 33) designed to alternately close the dies and create with the punch associated with the die a closed compaction volume.

  • the compression plate (231; 331) occupies a reduced space with respect to the rotary plate (21; 31) since it is not necessary for it to come and close all the dies (210; 310) of said rotary plate (21; 31), in particular it occupies a reduced surface area compared to the surface of the turntable (21; 31).
  • the compression plate (231; 331) is mounted on a support (232; 333) which is fixed relative to the frame 1, so that the compression plate (231; 331) alternately covers a number of dies (210; 310) adjacent due to the rotation of the turntable (21; 31).

It can be seen that according to this example, the final compaction volume (Vf) is reached when the punch 221 is on the compaction roller 224 which imparts the final compaction force to the powder mixture used to form the tablet.

  • the fact of reducing the speed of rotation of the turret reduces the tangential speed and increases the action times of the various functions of the press device (the functions representing angular sectors of the rotary table), which is particularly advantageous.
  • the proposed press device also has advantages in terms of size. Indeed, in addition to the fact that it is not necessary to provide additional equipment for handling and / or refocusing the shelves, the proposed configuration makes it possible to have a number of stations per set of compaction (equivalent to the number of dies per turret) smaller compared to a press with a single compaction assembly and two outlets, for example, which is larger and includes a large number of stations.
