Abstract
A tablet counter. Generally disk-shaped tablets on a horizontal circular table are swept to the edge by a rotating arm. A chamfer at such edge tips them edgewise into a vertical opening formed between inner and outer cylindrical walls at the periphery of the table. The opening is of a width to hold the tablets in vertical rolling position and contains one or more helical ramps forming chutes along which the tablets roll to and past a counting device and thence to a receptacle through a gate controlled by such device.

10 Clairm, 5 Drawing Figures mammals 8 km sum 1 or 3 rr'n \ ATTORNEYS PATENTEU M13 3 I973 SHEET 3 OF 3 INVENTOR WILLI AM GEORGE ROAST ATTORNEYS APPARATUS FOR DELIVERING TABLETS AND THE LIKE BACKGROUND OF THE INVENTION ing devices are available, and for efficient use of such devices it is necessary for a succession of single tablets to be passed rapidly past the counting head.
SUMMARY OF THE INVENTION According to the present invention there is provided apparatus for delivering a succession of single tablets to a counting device which apparatus comprises a horizontal circular table having a downwardly sloping periphery, and at least one chute forming at least part of a helix concentric with the circular table, of a diameter substantially equal to that of the table and disposed below the table in a position to receive tablets edgewise from the sloping edge of the table and of a width to hold the tablets in vertical edgewise position to roll down the chute. A vertical drive shaft passing centrally through the table carries at least one arcuate rotor arm adapted to sweep substantially the whole of the upper surface of the table on rotation of the shaft, and motor means is connected to the drive shaft and adapted to rotate the shaft.
The arcuate rotor arm desirably has a radius of curvature substantially the same as the radius of the circular table, and is rotated about the drive shaft so that the convex side of the rotor art is the leading edge. Tablets, which must be generally in the form of discs, when placed on the table will lie on their flattened sides and on rotation of the rotor arm are swept to the edge of the table and on to the downwardly sloping edge. The outward momentum of the tablets and the downward slope causes them to fall over the edge and in doing so rotate or tip through 90 to fall edgewise in the helical chute which is of a width to hold them in edgewise rolling position. The tablets then roll on their edges down the chute which leads past the counting head of a counting device and thence to a suitable receptacle.
The helical part of the chute desirably runs downwardly in the opposite direction to the direction of rotation of the rotor arm. Thus, if the chute forms a left hand helix, the rotor arm rotates in a clockwise direction viewed from above, and if the chute forms a right hand helix, the rotation of the rotor arm is in a counter-clockwise direction viewed from above.
DESCRIPTION OF PREFERRED EMBODIMENTS The invention will now be further described with reference to the accompanying drawings, in which:
FIG. 1 is a plan view of one embodiment of the invention;
FIG. 2 is a side view, partly cut away, of the apparatus shown in FIG. 1;
FIG. 3 is a side view, partly cut away, of a modification of the apparatus shown in FIGS. 1 and 2 together with an electronic counting device;
. in FIG. 3; and
FIG. 5 is a side view of a further modification in which an apparatus like that of FIG. 3 is provided with a mechanical counting device.
FIGS. 1 and 2, in which the same reference numerals denote the same parts, a circular table 10 having a chamfered periphery 11 is formed by one end face of an inner cylinder 12. A rotor arm comprising two arcuate arms 13 and 14 is fixedly mounted on a shaft 15 which may be driven in a counter-clockwise direction (FIG. 1) by a variable-speed electric motor16. The arcuate rotor arms 13 and 14 have a radius of curvature equal to the radius of the inner cylinder 12.
The inner cylinder is closely surrounded by a coaxial outer cylinder 18 and the space between the inner and outer cylinders is chosen to be slightly greater than the thickness, but less than the diameter, of the tablets 5 which are to be used with the apparatus. Between the inner and outer cylinders is a spiral chute or raceway 19 ending in a straight raceway 20 which leads to a counting device (not shown).
In operation, tablets 5 are fed to the table 10. Rotation of the arms 13 and 14 results in'the tablets being swept to the chamfered edge 11 where the tablets turn on to their edges as they drop into the raceway 19. The tablets travel down the raceway 19 and emerge on raceway 20 as a single stream sufficiently spaced to enable them to-be counted electronically.
It will be appreciated that in theembodiment shown in FIGS. 1 and 2 the helical raceway 19 must make at least one complete circuit of the inner cylinder 12 in order to catch all the tablets falling from the table 10. Although it has not been shown for the sake of clarity, in practice a plurality of raceways, for example four, might be used, in which case each raceway need only continue to follow a helical path around the inner cylinder until that raceway reached a point belowthe' start of the next raceway.
The raceways would conveniently emerge through the outer cylinder 18 adjacent one another.
The angle of descent of the raceways should be large to obtain a rapid throughput of tablets, but not so large that some tablets will drop a great distance to reach the raceway, because of the risk of tablet fragmentation. Increasing the number of raceways will reduce the maximum possible drop of the tablets and thereby enable steeper gradients to be used, and will allow an increase in the rate of delivery and counting of tablets.
The apparatus shown in FIGS. 3 and 4 is essentially the same as that shown in FIGS. 1 and 2, having a table 30 with a chamfered periphery 31, an inner cylinder 32, an outer cylinder 33 and a helical chute or raceway 34. However, a single rotor arm 35 is shown. The apparatus is shown set up for use with a photoelectric counting head 36 which is connected to an electronic counter 37 on which the apparatus stands. The raceway 34 runs past the counting head 36 and leads to a receptacle 38. The reference numeral 39 denotes a deflector plate which is used to transfer the flow of tablets from the receptacle 38 to another receptacle 38', and may be actuated in response to the count registered on the head 36. Alternatively, a simple gate may be used to close the chute 34 for a pre-set time between counts to enable the receptacle 38 to be changed.
FIG. 5 shows a tablet feeding device like that shown in FIG. 3 but adapted to feed a linear counter, having a table 40 with a chamfered periphery 41, an inner cylinder 42, an outer cylinder 43, helical raceways 44 a, b, and c, and a single rotor arm 45. There is also shown a storage hopper 49 from which tablets can be fed to the table 40 below the hopper. Each raceway 44 leads to a straight or sloping chute 46. Chutes 46 a, b, c, are shown, and are connected respectively to the helical raceways 44 a, b, and c. In the chutes 46 are an upper division plate 47 and a lower division plate 48. The chutes 46 and division plates 47 and 48 form a mechanical linear counter. The lower division plate 48 is fitted near the end of the raceways 46, and the upper division plate 47 is fitted at for example 25 or 50 tablet diameters from the lower division plate.
The counting operation comprises'closing the lower division plate 48 and opening the upper division plate 47, and allowing the tablets to fill the raceways between the two division plates. The upper division plate 47 is then closed between the 25th and 26 or 50th and 51st tablets and the lower division plate is thereafter opened, allowing 25 or 50 tablets from each raceway 46 to fall into a receptacle or receptacles. lf there are, for example, raceways 46, 250 or 500 tablets can be counted in one operation.
