DESCRIPTION:
BRIEF SUMMARY
The invention relates to an automatic machine for packaging tablets in gelatine capsules. The covers which constitute the capsules are initially separate from one another and are located in bulk in respective stations of the machine which uses in part the concepts of European application EP-A-0 615 739 and to which the broadest reference is made. The machine is equipped with groups of bushes located on the periphery of a turntable or on a transfer which, with an intermittent movement, causes the same bushes to interact in succession with the following operating stations: a station which feeds into the bushes a bottom cover of the capsules, hereinafter called in short "base", orientated with the mouth upwards; a station which feeds the tablets into the bushes, above the base; a station which feeds into the bushes the closing cover of the capsules, hereinafter called in short "lid", orientated with the mouth downwards; a station which checks the correct presence in the bushes of the assembly of the base, of the tablet and of the lid and which signals any anomalies to a processor which controls the functioning of the machine; a station which subjects the assembly of the base, of the tablet and of the lid to a suitable compression in the axial direction to cause the tablet to enter into the base and into the lid and become enclosed in these two components; a station which takes care of the ejection from the bushes of the tablets enclosed in the gelatine capsules and which, on signalling from the presence checking station, is capable of sorting the correctly packaged product from that which is defective; a station which takes care of the cleaning of the bushes before these are to be introduced into a new work cycle.
Major characteristics of the invention, and the advantages which derive therefrom, will appear more clearly from the following description of a preferred embodiment of the same, illustrated purely by way of non-limiting example in the figures of the attached ten plates of drawings, in which:
FIG. 1 is a diagrammatic plan view of the machine in the turntable version;
FIG. 2 is a lateral view with parts in section of the station which feeds the base of the capsules;
FIG. 3 is a view in frontal elevation of the intermediate part of the station in FIG. 2;
FIG. 4 illustrates further details of the station in FIG. 2, sectioned along line IV--IV;
FIGS. 5 and 6 illustrate an enlarged detail of the station in FIG. 2, with the different arrangement with which the bases of the capsules can arrive in the seat of the orientation device;
FIGS. 7 and 8 illustrate a further, enlarged detail of the station in FIG. 2 and demonstrate the different manner of operating the orientation device;
FIG. 9 is a plan view from above of the seats of the orientation device of the station in FIG. 2;
FIG. 10 is a diagrammatic view in perspective of the station for feeding the tablets;
FIGS. 11, 12, 13, 14, 15 and 16 are lateral views with parts in section of the end structure of the station in FIG. 10, depicted in the same number of work phases;
FIG. 17 illustrates laterally with parts in section the station for feeding the lids of the capsules;
FIG. 18 illustrates laterally with parts in section and in the work position the station which detects the presence or absence in the support bushes of the base, of the lid and of the interposed tablet;
FIG. 19 illustrates laterally with parts in section and in the work position the station for inserting and enclosing the tablet in the base and in the lid of the capsule;
FIG. 20 illustrates laterally with parts in section and in the active condition the station for discharge of the packaged tablet by the support bushes;
FIG. 21 illustrates laterally with parts in section and in the active condition the station for cleaning the bushes.
It can be seen from FIG. 1 that the machine comprises groups of bushes 1 for support of the covers of the capsules and of the tablets to be packaged, located in quantity and with an order which is predetermined and may also be different from that illustrated,
