Abstract

La présente invention concerne un dispositif d'impression de comprimés (1) pourvu d'un mécanisme de transport annulaire (20), d'une partie d'impression (30) et d'un mécanisme de retournement (70). Le mécanisme de transport annulaire (20) transporte un comprimé (9) le long d'un trajet de transport annulaire tout en retenant le comprimé (9) par aspiration. La partie d'impression (30) imprime une image sur une surface du comprimé (9) au niveau d'une position de traitement sur le trajet de transport du mécanisme de transport annulaire (20). Le mécanisme de retournement (70) retourne le comprimé (9) à l'envers au niveau d'une position de retournement sur le trajet de transport du mécanisme de transport annulaire (20). Ce système permet une impression sur les deux surfaces du comprimé (9) au niveau de la même position de traitement sur le trajet de transport. Grâce à ce système, il est possible de réduire le nombre d'éléments nécessaires dans le dispositif et d'augmenter la compacité du dispositif.
