FIGS. 6, 7 and 8 are three schematic side views, with parts shown as cross-sectional views and parts removed for the sake of clarity, of the feeding assembly ofFIG. 1 illustrated in three different operating positions. - With reference to
FIGS. 1 and 2 , denoted as a whole by reference numeral 1 is a feeding assembly todose tablets 2, in particular micro-tablets of pharmaceutical products, incapsules 3, each of which comprises a substantially cup-shaped bottom 4 and alid 5 to close thebottom 4. - The feeding assembly 1 defines part of a
machine 6 forfilling capsules 3, and comprises adosing wheel 7 provided with adistribution platen 8, which is mounted so as to rotate continuously about an axis ofrotation 9 substantially parallel to avertical direction 10, and is limited by a flatinner bottom wall 11 that is substantially perpendicular to theaxis 9. - The
platen 8 is provided with a plurality ofgroups 12 ofdosing holes 13 that pass through thewall 11 parallel to thedirection 10. Thegroups 12 are obtained along a perimeter edge of theplaten 8, and are evenly distributed around theaxis 9. - The
wheel 7 further comprises anupper trimming disc 14, which is fixed to aframe 15 of themachine 6, extends above theplaten 8, has an annular shape, and is radially limited by aninner wall 16, the distance of which from theaxis 9 increases in adirection 17 of movement of theplaten 8 about theaxis 9. - In particular, the distance of the
wall 16 from theaxis 9 ranges from a minimum value, in correspondence to which theholes 13 are covered by thedisc 14, and a maximum value, in correspondence to which thedisc 14 extends outside theplaten 8 and is radially staggered with respect to thegroups 12 ofholes 13. - The
groups 12 ofholes 13 are moved by theplaten 8 around theaxis 9 and through adosing station 18, in the area of which thedisc 14 is provided with aslot 19 suitable to allow afirst control device 20 mounted upstream of thestation 18 in thedirection 17 to check for the presence oftablets 2 in each hole and asecond control device 21 mounted downstream of thestation 18 in thedirection 17 to check for the absence oftablets 2 in theholes 13. - As illustrated in
FIGS. 3, 5 and 6 , thewheel 7 further comprises alower closing disc 22, which is mounted under theplaten 8 coaxially with theaxis 9, is coupled in an angularly fixed manner to theplaten 8 and which, in correspondence with eachgroup 12 ofholes 13, has anopening 23 obtained through thedisc 22 in thedirection 10. - The
disc 22 supports a plurality ofclosing plates 24, which are evenly distributed around theaxis 9, and are equal in number to the number of thegroups 12, and each of which has a respective plurality oftransfer holes 25 equal in number to the number of theholes 13 in agroup 12 ofholes 13. - The
plates 24 are coupled to thedisc 22 in a sliding manner so as to move radially between a closing position (FIG. 6 ), in which therespective holes direction 10 to prevent thetablets 2 from disengaging theholes 13, and an opening position (not illustrated), in which therespective holes direction 10 to allow thetablets 2 to fall out of theholes 13. - Each
plate 24 is moved to its closing position, and normally kept in that position, by aspring 26, which is interposed between theplaten 8 and theplate 24, and defines part of anoperating device 26 a configured to move theplates 24 between their opening and closing positions. - The
device 26 a further comprises acam 27, which is mounted in the area of thestation 18; and, for eachplate 24, arespective cam follower 28. - The
cam follower 28 comprises a supportingbracket 29 coupled in a rotating manner to theplate 24 so as to rotate, with respect to theplate 24, about afulcrum axis 30 crosswise to thedirection 10; and a cam follower roller bearing 31 coupled in a rotating manner to thebracket 29 so as to rotate, with respect to thebracket 29, about an axis ofrotation 32 parallel to thedirection 10. - The
cam follower 28 is mobile about theaxis 30 between a lowered operating position (FIGS. 6 and 7 ), in which the roller bearing 31 intercepts thecam 27 in order to move therespective plate 24 to its opening position, and a raised rest position (FIG. 8 ), in which the roller bearing 31 avoids thecam 27 in order to keep therespective plate 24 in its closing position and so prevent thetablets 2 from being fed into therespective bottom 4. - With reference to
FIG. 4 , on the outside of thedosing station 18, theopenings 23 are closed by anannular disc 33, which is fixed to theframe 15 under thedisc 22, extends around theaxis 9, and has, in the area of thedosing station 18, anopening 34 that passes through thedisk 33 in thedirection 10 to permit the passage of thetablets 2. - The
disc 33 closes eachopening 23 to define arespective suction chamber 35, which is moved by thewheel 7 about theaxis 9, and is suitable to be connected by means of at least onesuction channel 36 passing through thedisc 22 to apneumatic manifold 37 provided in thedisc 33. - The
manifold 37 extends around theaxis 9 at an angle of less than 360°, and is shaped to connect thechambers 35 to a pneumatic suction device of a known type that is not illustrated here upstream and downstream of thestation 18 in thedirection 17. - In connection with the above description, it is important to note that the
cam followers 28 are moved from their lowered operating positions to their raised rest positions by a jet of compressed air delivered against thecam followers 28 through anoutlet hole 38 obtained in thedisc 33 upstream of thestation 18 in thedirection 17. - The
cam followers 28 are moved from their raised rest positions to their lowered operating positions by a contact roller (not illustrated) mounted along the path of movement of thecam followers 28 about theaxis 9. - As illustrated in
FIGS. 6 to 8 , the wheel further comprises afeeding drum 39, which is coupled in an angularly fixed manner to theplaten 8, and comprises, in turn, for eachgroup 12 ofholes 13, arespective feeding channel 40, which extends below thedisc 33 to transfer thetablets 2 from theholes 13 into therespective bottom 4. - Each
channel 40 comprises, in succession and starting from therespective opening 23, aninput segment 41, which is funnel-shaped and converges downwards, and is obtained in an upper disc angularly integral with theplaten 8; a vibratingintermediate segment 43 obtained in anintermediate disc 44 hooked to thedisc 42 by means of a plurality offlexible hooking tongues 45; and anoutput segment 46, which faces therespective bottom 4, and is obtained in alower disc 47 angularly integral with thedisc 42. - To prevent the
tablets 2 from getting jammed in thesegments 43, thedisc 44 is made to vibrate by means of avibrating device 48, which is mounted on theframe 15 by means of the interposition of adamping device 49, and imparts a vibrating motion to a supportingbracket 50, on which aroller 51 is mounted in a rotating manner and arranged so as to come into contact thedisc 44. - Each
segment 46 is provided with a capacitive transducer 52 (described and illustrated in patent application WO-2006/035285-A2 filed by this same Applicant, the content of which is fully incorporated in this patent application), which defines, with thecapacitive transducers 52 of theother segments 46, part of aweighing system 53 further comprising aprocessing unit 54 connected to thecapacitive transducers 52. - The
bottoms 4 are moved in succession through thestation 18, each in phase with arespective feeding channel 40, by apocket conveyor 55 extending across themachine 6. - The
conveyor 55 is wound in a loop about a plurality of spools (of which only thespool 56 on thewheel 7 is illustrated inFIG. 6 ), and is provided with a plurality ofpockets 57, which are substantially cup shaped with the concavity upwards, are evenly distributed along theconveyor 55, and each of which is designed to receive arespective bottom 4 arranged inside therespective pocket 57 with its concavity upwards. - In use, when the
wheel 7 rotates about theaxis 9, thetablets 2 contained in theplaten 8 are arranged inside theholes 13 which are gradually uncovered by theinner wall 16 of thetrimming disc 14. - The
holes 13 are filled upstream of thedosing station 18 and of thecam 27 in thedirection 17 and starting from an instant in which theplates 24 are arranged in their closing positions, thesuction chambers 35 are closed by thedisc 33 so that thetablets 2 can be sucked into theholes 13, and thecam followers 28 are arranged in their lowered operating positions. - The
groups 12 ofholes 13 are moved in succession into theslot 19, under thecontrol device 20 in order to check for the presence of thetablets 2 in eachhole 13 of eachgroup 12, and through thestation 18. - In the area of the
dosing station 18, eachgroup 12 ofholes 13 and therespective feeding channel 40 are moved in phase with arespective bottom 4, therespective cam follower 28 engages thecam 27 to move therespective plate 24 into its opening position, and thetablets 2 contained in theholes 13 fall due to the force of gravity first through the opening 23 in thedisc 22 and theopening 34 in thedisc 33, and then along thechannel 40 and into thebottom 4. - Downstream of the
station 18 in thedirection 17, eachcam follower 28 disengages thecam 27 to allow therespective spring 26 to move therespective plate 24 back into its closing position, and thegroups 12 ofholes 13 are moved in succession under thecontrol device 21 in order to check for the absence oftablets 2 in theholes 13. - In connection with the above description, it is important to note that each
pocket 57 is associated with a lower pushingmember 58, which lifts therespective bottom 4 into theoutput segment 46 to allow the respectivecapacitive transducer 52 first of all to measure the weight of thebottom 4, and then the weight of thebottom 4 with thetablets 2 it contains, and to allow theprocessing unit 54 to calculate the weight of thetablets 2 contained in thebottom 4 as the difference between the two values. - As described above, the dosing of the
tablets 2 in thebottoms 4 is prevented by the selective activation of the jet of compressed aid that is delivered through theoutlet hole 38 and by the consequent movement of thecam followers 28 into their raised rest positions. - Since the
closing plates 24 are made to move around theaxis 9 with thedistribution platen 8 and, thus, with thegroups 12 ofdosing holes 13, and since the movement by theplates 24 from their closing positions to their opening positions is relatively small, the integrity of thetablets 2 is not undermined by the relative motion of theplaten 8 and theplates 24.
