Abstract:
A machine (100) for the treatment of pharmaceutical products (P) comprises a pan (2) that revolves about an axis of rotation (X) and a dispensing unit (3) designed to disperse a coating material inside the pan (2) over a mass (M) of the products (P) located in the pan (2). The pan (2) has an opening (7) for feeding the products to be treated (P) into the pan (2), and an opening (8) for feeding the products (PT) already treated with the coating material out of the pan (2), the infeed opening (7) and the outfeed opening (8) being separate and independent of each other. A portion (K) of the inside surface of the pan (2) is equipped with at least one helical flow regulating fin (4, 5, 6) designed to facilitate inflow (F3) of the products to be treated (P) into the pan (2) during the feeding of the products (P) into the pan (2) through the infeed opening (7) when the pan (2) itself revolves in a first direction of rotation (F1), and to cause outflow (F4) of the treated products (PT) from the pan (2) during the outfeed of the treated products (PT) from the pan (2) through the outfeed opening (8) when the pan (2) itself revolves in a second direction of rotation (F2), opposite to the first direction of rotation (F1).
Abstract:
A tablet press machine (100) comprises: a hopper (1) for feeding a powder or granular product (2) to a first disc (3a) that rotates about an axis (X) and is equipped with evenly distributed holes or dies (3); a second and third disc (4, 6) that are positioned above and below the first disc (3a), respectively, rotate about the axis (X) and support respective pluralities of upper and lower reciprocating punches (5, 7). The punches (5, 7) are driven towards and away from each other when they are aligned with the dies (3) in such a way as to compress the product (2). Each of the punches (5, 7) comprises a cylindrical shank (8), one end of which is equipped with a working head (10) and sealed protection means (11) acting on the cylindrical shank (8) itself. The sealed protection means (11) comprise, for each punch (5, 7), a concertinaed sleeve (12) covering the cylindrical shank (8) and having an annular portion (13) constituting its far end relative to the working head (10), forming an annular seal and providing also a removable element used to attach support means (14) that protrude from the respective disc (4, 6). The near end (15) of each concertinaed sleeve (12) relative to the working head (10) presents an enlarged annular portion (16) that engages with a matching annular groove (17) in the cylindrical shank (8) to provide a tight seal.
Abstract:
A capsule filling machine (1) for the production of hard gelatine capsules (C) of the type with a capsule lid and a capsule body and containing a product, preferably a pharmaceutical product, comprises at least a first station (2), rotating with a stepping motion, for supporting and moving at least one capsule body (3) to a second station (4) for feeding and dosing the product, the second station (4) rotating with a stepping motion synchrozised with that of the first station (2) and having at least one cylindrical hole (5) containing a dose (6) of the product; between the first station (2) and the second station (4) there being slide means (7) for supporting and moving the capsule body (3) between a first operating position, in which the capsule body (3) is distanced from a lower end (5a) of the cylindrical hole (5), and a second operating position, in which the capsule body (3) is exactly below the lower end (5a) of the cylindrical hole (5), allowing the dose of product (6) to be released into the capsule body (3); the slide means (7) comprising a first and a second support (8, 9) operating in conjunction with one another, the first support (8) being carried by the first station (2), rotating and supporting a capsule body (3); the second support (9) being carried by the second station (4), rotating and, in the first operating position, located below the end (5a) of the cylindrical hole (5) to close the end (5a); there also being drive means (10) acting on at least the first support (8) to move the first support (8) towards the second support (9) with both radial and transversal motion until the first support (8) gradually makes contact with the second support (9), with a consequent thrust by the first support (8) on the second support (9) pushing the second support (9) back away from the first operating position to the second operationg position, allowing the dose (6) to be released into the capsule body (3).
Abstract:
Respective secondary thrusters (70, 71) are added to the primary horizontal thruster (7) and primary vertical thruster (12) of a guiding device of the known type and the guide channel (6) is provided with dimensions such that the steps of guiding and feeding the capsule (C) are performed with minor successive displacements of the said capsule (C). The primary vertical thruster (12) operates, in a position distant from the sleeve (13) of the capping machine so as to allow discarding and free removal of the defective capsules (C) which have a double lid (C2) or the capsule parts which reach this thruster. The last section (206) of the guide channel (6) inside which the secondary vertical thruster (71) operates, has a width slightly smaller than that of the upstream section (106) of the said channel so as to retain firmly the end of the defective capsule (C) having lids (C2) on opposite ends of a base (C1). Such a defective capsule (C), which is arranged horizontally or inclined by the primary horizontal thruster (7), is then acted on by the tip (112) of the primary vertical thruster (12) and by a face (171) of the secondary vertical thruster (71) which discard this defective capsule (C) from the bottom of the guide channel (6). On the other hand, a capsule (C) correctly fitted with a lid (C2) and oriented vertically by the primary vertical thruster (12) remains inside the guide channel (6), is then displaced inside the latter by the secondary horizontal thruster (70) and then a leading face (271) of the secondary vertical thruster (71) acts on this capsule and accompanies the said capsule (C) during the complete stroke for insertion inside the sleeve (13) of the capping machine.
Abstract:
A carousel carries a holder with product to be dosed and includes a lower disc fitted with peripheral sets of dosing holes into which plungers insert and press in successive stages doses of product. The carousel also includes fixed bodies and radially moveable bodies with seatings for supporting tops and bottoms of capsules. Lower bodies support extensions that close the lower ends of dosing holes in the successive stages, and opposing members are provided to support the moveable assemblies. With only one dosing disc, it is possible to form doses of product of different densities and masses and of different heights by varying the heights of the sets of plungers. A chamber defined by a sweeper wall and containing no product is provided with a plunger station that completes the pressing of this final quantity of product, before a subsequent plunger station discharges the product into the capsule bottoms.
Abstract:
An ejection and conveying device mounted in a rotary pressing tabletting machine having matrices supported by a rotating table, whereinto upper punches and lower punches enter and come out, while tablets come out at an ejection station; the device includes a plate fastened to the machine and positioned under the table. Part of the plate is located under the machine's ejection station, while a rotating disk is placed inside a raised border of the plate and has a plurality of hollows whereinto the ejected tablets fall so that the tablets are drawn by the disk up to be positioned above one or more holes made in the bottom of the plate and from which holes discharge channels depart. The tablets pass through the holes and are brought away by the channels.
