Abstract:
1. Machine for filling capsules ( 2 ) with powdery pharmaceutical products, each capsule ( 2 ) comprising a bottom ( 3 ) and a cap ( 4 ) for closing the bottom ( 3 ), the machine comprising a conveyor device ( 21 ) to continuously move forward each bottom ( 3 ) along a determined path (P); a tank ( 60 ) containing at least a pharmaceutical product; at least a dosing wheel ( 10 b ) mounted to continuously rotate around a first rotation axis ( 12 ); at least a dosing device ( 36 ), which comprises two dosing elements ( 47 , 87 ) engaged with each other, and is moved forward by the dosing wheel ( 10 b ) in the first place through a sampling station of a determined amount of pharmaceutical product from the tank ( 60 ) and then along a portion of the path (P) in phase with a relative bottom ( 3 ) to transfer the pharmaceutical product inside the bottom ( 3 ); an actuating device ( 40 , 90 ) to axially move the dosing elements ( 47 , 87 ) in a direction ( 13 ) parallel to said axis ( 12 ) and comprising a first cam ( 41 ) and a first tappet ( 44 ) supported by a first said dosing element ( 47 ) and engaged with the first cam ( 41 ); a stopping element ( 86 ); and pushing means ( 89 ) to move and, normally, to keep a second said dosing element ( 87 ) in contact with the stopping element ( 86 ); the two dosing elements ( 47 , 87 ) being mobile in said direction ( 13 ) with respective identical laws of motion only under the thrust of the first tappet ( 44 ) and defining between them, when the second dosing element ( 87 ) is in contact with the stopping element ( 86 ), a dosing chamber ( 59 ) having a determined volume; the machine being characterized in that the actuating device ( 40 , 90 ) further comprises a first actuating member ( 98 ), which is mounted in said sampling station, is mobile in said direction ( 13 ) to move the second dosing element ( 87 ) with respect to the first dosing element ( 47 ) and to compact the pharmaceutical product inside the dosing chamber ( 59 ), and is mounted to swing, under the thrust of the second dosing element ( 87 ) and against the action of a relative shock-absorbing device ( 94 ) around a second rotation axis ( 12 ) parallel to said direction ( 13 ).
