Definitions
- the present invention included in the International Classification B 30b, refers to the technology of packaging machines and specifically to high-performance tablets' compressing machines.
- the compressing equipment In the previous state of the art can be found several different models of tablets' compressing machines.
- the compressing equipment consists of two opposite pistons, vertically set up above and below the peripheral zone of a rotating horizontal disc equipped with peripheral piercing holes filled with doses of powder to be compressed.
- This traditional configuration entails considerable structural hassles, causing troubles to the operation and the maintenance of the machine.
- the main flaws of the traditional compressing machines can be charged on the fact that the traditional equipment, consisting of two long vertical compressing pistons, requires a troublesome precision in order to ensure the coaxiality necessary to center the peripheral holes of the main disc.
- Figure 1 presents a general scheme of the basic kinematisms of the compressing machine, consisting in a main wheel externally provided with a set of four operating devices that perform,
- main wheel is also internally provided with a set of four equipments that, in synchronized combination with the external devices, co-operate in performing all the steps of the continuous operative loop.
- Figure 2 shows in greater detail the external devices and the equipment inside the main wheel, combined in order to perform the feeding phase of the single doses of powder to be compressed.
- Figure 3 shows an enlarged radial section of the devices and the instruments to set the exact
- Figure 4 shows the external devices and the internal equipment to grade and adjust the first compression phase.
- Figure 5 is a enlarged radial section of the devices and instruments for the first compression.
- Figure 6 shows the external devices and the internal instruments to grade the second compression phase.
- Figure 7 is a enlarged radial section of the devices and instruments that adjust the second compression phase.
- Figure 8 shows the devices that perform the phase of the selective final expulsion of the compressed tablets.
- Figure 9 is a enlarged radial section of the devices and instruments for the expulsion of the compressed tablets.
- Figure 10 represents a set of four mechanisms inside the main wheel.
- Figure 11 shows an enlarged radial section of the operation of the return tracks, specially outlined in order to allow the internal movements of the compressing pistons.
- Figure 12 is a general perspective view of the compressing machine in one of the possible configuration of structural lay-out.
- 4 indicates the external roller that performs the selective expulsion of the compressed tablets.
- 5 indicates the main wheel peripherally equipped with a set of small cylinders, inside which small pistons slide, whose radial movements are controlled from inside by the action of a four equipment operative set.
- 17 indicates the eccentric device that sets the compression grade of the first compressing phase.
- 21, 22, 23 and 24 indicate the profiled tracks that connect and guide the return excursions to the inside of the compressing pistons.
- 25 indicates the expulsion cells of the selected tablets.
- 29 indicates the single powder dose after the first compression.
- 1, 2, 3 and 4 constitute the set of four operative devices set up on the outside of the main wheel and that 11, 12, 13 and 14 constitute the set of four instruments co-operating from the inside of the main wheel.
- 11, 12, 13 and 14 constitute the set of four instruments co-operating from the inside of the main wheel.
- 21, 22, 23 and 24 indicate the
- the number of the compressing pistons (15) is just half of the double set of compressing opposite pistons that is usually provided in the traditional compressing machines.
- the characteristic guide zone of the counterfoil (15) has a diameter much bigger than the tablets' diameter, this ensuring a greater
