Description
- The present invention relates to a capsule filling machine for the production of hard gelatin capsules containing pharmaceutical material.
- In particular, the pharmaceutical material in the hard gelatin capsules of the type with a capsule lid and a capsule body to which the present invention advantageously refers is in the form of particles, that is to say, micro-tablets or pellets.
- Generally speaking, a capsule filling machine of the known type currently used basically comprises a central turret or carrousel rotating with discontinuous or stepping motion and equipped with a plurality of operating units located along the edge of the turret and driven by the turret by means of reciprocating drive parts.
- Each operating unit on the turret comprises a slide supporting element for holding one or more capsules to be carried to a plurality of work stations in which successive operating steps take place, in accordance with a known method. For example, closed capsule feed and angled positioning, subsequent opening of each capsule, that is to say, separation of the capsule body from the capsule lid, feeding a quantity of pharmaceutical material into the capsule body, then closing each capsule body with the relative capsule lid and, finally, discharge of the closed filled capsule obtained in this way.
- In this process cycle, dosing units of known type, each comprising a hollow punch which forms a cylinder and houses a piston (normally pneumatically driven), pick up the pharmaceutical material by lowering the cylinder into a tank containing the material which is attached to the turret, together with an upward movement of the piston to allow dosing, that is to say, to allow the pharmaceutical material to be held in the cylinder previously immersed in the tank.
- The cylinder is then lifted out of the tank and, after a scraping or brushing step to remove any excess micro-tablets, the piston downstroke is activated to push the product, dosed according to the volume of the cylindrical chamber, into the capsule body, aligned in succession with the corresponding cylinder.
- At present, the above-mentioned dosing units are used for efficient, precision dosing of pharmaceutical material in powder form, whilst if capsules are to be filled with particulate material such as micro-tablets or pellets, dosing is not as precise.
- Whilst the piston can pick up precise and constant volumes of powdered pharmaceutical material in the hollow cylinder, in the case of micro-tablets, the piston cannot exert sufficient pick up force on the micro-tablets to guarantee a given and constant number of micro-tablets which will then be released into each capsule body.
- The aim of the present invention is to produce a capsule filling machine which can overcome the above-mentioned disadvantage of the prior art.
- In particular, the aim of the present invention is to produce a capsule filling machine which guarantees high precision dosing.
- Another aim of the present invention is to propose a capsule filling machine which, together with the above-mentioned precision dosing, continues to guarantee the reliability, productivity and safety levels required of such machines, as well as the production speed typical of current capsule filling machine, in particular of high productivity continuous-motion capsule filling machines.
- Accordingly, the present invention provides a capsule filling machine for the production of hard gelatin capsules of the type with a capsule lid and a capsule body containing particles of pharmaceutical material, in particular micro-tablets or pellets, the machine comprising a first rotary carrousel, which supports a plurality of slide units for picking up and handling the capsules in order to open then close the capsules by separating then joining the capsule lids and the capsule bodies; a second carrousel, which rotates in such a way that it is synchronised with the first carousel, having a plurality of reciprocating doser means moving between a first operating position in which the doser means are designed to pick up pharmaceutical material from a tank containing the material which is attached to the machine and a second operating position in which they release the material into the capsule bodies. The machine is characterised in that the doser means each comprise a hollow nozzle with a plurality of seats on its edge for picking up and holding the particulate pharmaceutical material, each seat communicating with pneumatic means. The pneumatic means comprise pneumatic vacuum means which, in the first operating position, suck up and hold individual particles of the pharmaceutical material in respective seats of the nozzle, and pressurised pneumatic means which generate a flow that discharges the particles from the seats in the second operating position to allow the above-mentioned release of material into the capsule bodies.
- The features and advantages of the invention are more clearly illustrated in the detailed description which follows, with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention without limiting the scope of the inventive concept, and in which:
-
FIG. 1 is a diagram illustrating the operating cycle of a capsule filling machine made according to the present invention; -
FIGS. 2 and 3 are side views with some parts cut away and others in cross-section of a detail of the capsule filling machine made according to the present invention in two different operating configurations; -
FIG. 4 is a front view with some parts in cross-section of a detail of a particular component of the capsule filling machine illustrated inFIGS. 2 and 3 ; -
FIG. 5 is a cross-section of the component illustrated inFIG. 4 ; -
FIG. 6 is a detail of a part of the capsule filling machine illustrated inFIG. 1 . - With reference to
FIG. 1 , the capsule filling machine disclosed, labelled 10 as a whole, is used for filling capsules C of the known type with a capsule lid and a capsule body, labelled 13 and 14 respectively, with given quantities ofparticles 12 of pharmaceutical material, specifically pharmaceutical micro-tables 12 or pellets. - As illustrated in
FIGS. 1, 2 and 3, thecapsule filling machine 10 comprises a first carrousel 2 rotating about a vertical axis Z in the direction indicated by the arrow L and havingradial arms slide units 3 for picking upcapsule bodies 14 of capsules C and moving them in a horizontal direction, and atank 11 with a known, substantially toroidal shape, located at the base of thecapsule filling machine 10 and designed to hold a mass of micro-tablets 12 supplied from afeed hopper 30. - The
machine 10 also comprises a second carrousel 4 (FIG. 2 ), also rotating about the vertical axis Z, again in the direction indicated by arrow L inFIG. 1 and synchronised with the first rotary carrousel 2. Thecarrousel 4 is equipped with a plurality of micro-tablet 12 doser means 21. - As illustrated in
FIGS. 2, 3 and 6, the doser means 21 are mobile in a vertical direction parallel with the axis Z alternatively between a first, pick up operating position (FIGS. 2 and 6 ), in which themeans 21 are inside thetank 11 containing the micro-tablets 12 for picking up quantities consisting of a given number ofindividual micro-tablets 12 and, a second operating position for releasing the quantities of micro-tablets 12 into thecapsule body 14 of a capsule C (FIG. 3 ). - According to a known method, illustrated in
FIGS. 1, 2 and 3, the first rotary carrousel 2 picks up the capsules C from an upper hopper (of the known type and not illustrated), containing the empty capsules C, then the capsules C are individually placed in the pick up means 3, each of the means comprising twobushings capsule lid 13 from therelative capsule body 14, filling thecapsule body 14 with a quantity of micro-tablets 12 by means of thedosers 21, closing thecapsule body 14 with thecapsule lid 13 and, finally, discharge of the finished capsule C from thecapsule filling machine 10 at an outfeed and unloading zone S (FIG. 1 ). - As is better illustrated in
FIG. 4 , each of the doser means 21 comprises acylindrical rod 20 with afree end 20 a having a plurality of seats oropenings 25 on the edge, for picking up and holding individual micro-tablets 12. - Each of the
openings 25 on the edge is also controlled by pneumatic means 24 (FIG. 2 ), specifically pneumatic means 24 a for generating a vacuum and pneumatic means 24 b for generating a pressurised air jet. The means 24 a are designed so that, in the first operating position, they pick up by suction a given number of micro-tablets 12 held incorresponding openings 25 on the edge, whilst the means 24 b are designed so that, in the second operating position, they discharge and release the micro-tablets 12 into acapsule body 14 thanks to a pneumatic thrust coming out of theopenings 25. - More specifically, each opening 25 preferably has dimensions corresponding to the dimensions of the micro-tablets 12 contained in the
tank 11. In this way, positioning and holding theindividual micro-tablet 12 at the opening 25 results in precision sealed closing of the opening 25. - Again as illustrated in
FIG. 4 , eachopening 25 is preferably circular in shape, so that it forms a cylindrical cavity communicating with the pneumatic means 24 throughpipes 27. - As is better illustrated in
FIG. 4 andFIG. 5 , theopenings 25 on the edge are arranged in such a way that they are separated by angular spaces which are equal and relative to a longitudinal axis Z′ of thecylindrical rod 20. They are arranged in two or more adjacent horizontal planes. - The angular spaces separating the openings preferably have an angle α of around 120° between one opening 25 on the edge and the next.
- The pneumatic means 24 also comprise a central channel 18, inside the
cylindrical rod 20, for the circulation of air, whether pressurised or forming a vacuum, to theopenings 25 on the edge by means of thepipes 27. - The above-mentioned free pick up
end 20 a consists of anozzle 22 with a tubular body whose centralcylindrical cavity 23 has a constriction at the end, designed to form the central channel 18 for the passage of air forming a vacuum. - The top of the
nozzle 22 with the tubular body is, in turn, attached to a vertical hollow rod, forming thecylindrical rod 20, by a connectingzone 26. - As illustrated in
FIG. 2 , thehollow rod 20 is connected to selection valve means 50 controlling the pneumatic means 24. - The selection valve means 50 are preferably located on the
second carrousel 4 and connect the suction means 24 a to theopenings 25 in the first, pick up operating position illustrated inFIG. 2 , that is to say, with thenozzle 22 immersed in the mass of micro-tablets 12 contained in thetank 11 and, alternatively, switch to the connection between theopenings 25 and the pressurised air means 24 b, in the second operating position in which themicro-tablets 12 are released in to thecapsule body 14 by pneumatic discharge of the micro-tablets 12. - In particular, to allow a correct release of the micro-tablets 12 into the
capsule body 14, thearm 2 a of the first carrousel 2 (FIGS. 2 and 3 ) has achamber 19 which is substantially funnel-shaped, designed to engage with thenozzle 22 in the second, release operating position, allowing and facilitating micro-tablet 12 infeed into thecapsule body 14. - Operation of the
capsule filling machine 10 described so far can be easily inferred from the description above. - With micro-tablet 12 feed into the
tank 11 guaranteed by suitably loading theturret 30, thecapsule filling machine 10 automatically performs all of the guided capsule C filling operations, according to the successive steps of opening, filling, closing and, finally, discharge from themachine 10. - In particular, the filling step is performed by means of an operation whereby a predetermined number of micro-tablets 12 is picked up from the
tank 11. - This is done by lowering the
hollow rod 20, equipped with thenozzle 22, into the mass of micro-tablets 12, then activating the suction means 24 a designed to create a vacuum with a predetermined value, so that thenozzle 22 attracts and holds micro-tablets 12 at theopenings 25. - The
rod 20 is then lifted in the known way to the position illustrated inFIG. 3 , and thebushing 17 with thecapsule body 14 is moved horizontally to bring the capsule body precisely into position below the funnel-shaped chamber 19. - At this point, the selection valve means 50 switch the
hollow rod 20 connection from the suction means 24 a to the pressurised air means 24 b. - This causes the release of each of the micro-tablets 12 held in the
relative opening 25 into the funnel-shaped chamber 19 and, from here, into thecapsule body 14 of the capsule C being filled. - At this point the
bushing 17 supporting thecapsule body 14 is again moved, to the position illustrated inFIG. 2 , continuing the rotary path illustrated in the diagram inFIG. 1 with theupper bushing 15. - Therefore, the machine described above achieves the preset aims thanks to a simple feed nozzle structure which allows precise dosing of the number of micro-tablets to be inserted in the capsules. During testing, optimum dosing results were obtained with a number of
openings 25 for eachnozzle 22, and therefore, a number of micro-tablets 12, varying between thirteen and thirty. - Thanks to the construction of the pick up nozzle, the precise and constant number of micro-tablets 12 which fills the
capsule body 14 of each capsule C is precisely determined by the number ofopenings 25 in thenozzle 22, since a single micro-tablet 12 is held by suction in eachopening 25. - Obviously, varying the number of openings in the pick up means varies the number, and therefore the dosage, of the micro-tablets.
- The dimensions of the openings may vary, as may the profile of the cavities formed by the openings in the nozzle body.
- In addition to the total number of openings in each nozzle, the number of openings distributed in each plane and, therefore, their angular distribution, may also vary. There may be alternative embodiments of the nozzle body, including the connecting zone and the lower channel.
- The pneumatic means for suction and pressurised air connected to the hollow rod may be of various types and powers, depending on the applications.
- The invention described can be subject to other practical application modifications without thereby departing from the scope of the inventive concept as described in the claims.
