. 40 l Q I! l i IN VENTOR DONALD F. STEWART AGENT This is a continuation, of application Ser. No. 880,030, filed Nov. 26, 1969, now abandoned.
BACKGROUND OF THE INVENTION This invention relates to a device for feeding a measured volume of powder into a receiver and, in particular, to a volumetric powder feeding device which does not alter the bulk density of the powder being fed.
Introduction of a measured charge of powder into a receiver involves withdrawing a measured aliquot of the powder from a bulk supply and transferring it to the receiver. Various techniques and devices have been developed to make such transfer in commercial processes at high production rates, with an accurately measured and uniform volume being delivered in each instance. One example of such transfer is in the production of pharmaceutical capsules. Vacuum-pressure operated powder feeding devices are available in a variety of designs for this purpose. These devices are capable of metering the charge accurately but they change the bulk density and flow characteristics of the powder. Auger loaders, on the other hand, do not affect these characteristics of the powder, but they are incapable of metering the charge accurately. With increasing frequency, available powder feeding devices have been found to be incapable of meeting the requirements of special applications, such as the ability to charge a volume of powder without alteration of its bulk density. Devices available heretofore have not been able to transfer at a high production rate a uniform and accurately measured volume of powder without altering the bulk density characteristics thereof.
SUMMARY OF THE INVENTION According to the instant invention, there is now provided a device for charging into a receiver a uniform and accurately measured volume of powder without alteration of the bulk density of the powder, which device is capable of filling the receivers at a high rate of production. This device comprises a horizontally disposed base plate having an upper feed surface and a lower surface, and a dispensing aperture extending therethrough with a volume equal to the volume of the powder to be charged into the receiver. Cooperating with the lower surface of the base plate is a means for alternately opening and sealing the lower extremity of the dispensing aperture. There are also provided a means for drawing the powder along the feed surface to introduce it into the dispensing aperture and means for adjusting the level of the introduced powder to the level of the feed surface. After introduction and adjustment of the level of the powder in the dispensing aperture, the lower extremity of the aperture is opened and the powder is charged into the receiver below without alteration of its bulk density characteristics.
The instant device is suited to filling receivers at a high rate of production by providing a plurality of dispensing apertures in the base plate and opening and closing means, powder drawing means, and level adjusting means cooperatively associated therewith.
BRIEF DESCRIPTION OF THE DRAWINGS For a better understanding of the instant invention, reference is made to the accompanying drawings, wherein:
FIG. 1 is a top plan view of a powder feeding device of the instant invention with the doctoring blade not shown and the sliding plate in the closed position;
FIG. 2 is a sectional view of the embodiment of FIG. 1 along 2-2 with the doctoring blade shown;
FIG. 3 is a sectional view of the embodiment of FIG. 1 along 33 with the sliding plate in the closed position; and
FIG. 4 is a sectional view of the embodiment of FIG. 1 along 3-3 with the sliding plate in the open position.
DETAILED DESCRIPTION OF THE INVENTION The powder feeding device of the instant invention enables one to charge a measured volume of powder into a receiver accurately, uniformly and without alteration of the bulk density characteristics of the powder. It is also suited to charging a large number of receivers simultaneously and is capable of production rates far in excess of volumetric powder feeding devices available heretofore, especially those which do not alter bulk density during the charging process. With reference to FIG. 1 wherein is illustrated a top plan view of a preferred embodiment of the instant device, there is provided a horizontally disposed base plate 10 through which a plurality of dispensing apertures l 1 extend. The volume of apertures 11 equals the volume of powder to be charged. Mounted beneath base plate 10 is sliding plate 12, which is in sealing engagement with lower surface 14 of base plate 10. Associated with each dispensing aperture 11 is a passage 13 extending through sliding plate 12, such that when sliding plate 12 is in the closed position (as illustrated in FIGS. 1-3), passages 13 are each misaligned with their associated dispensing aperture 11 and when sliding plate 12 is in the open position (as illustrated in FIG. 4) passages 13 are each aligned with their associated dispensing aperture 11. With reference to FIG. 2, sliding plate 12 engages the lower surface 14 of base plate 10 so as to seal the lower extremity of dispensing apertures 11 when in the closed position. The powder to be charged is maintained at one end of hopper 20 of which plate 10 forms the base. With sliding plate 12 in the closed position, powder 21 is drawn along the upper feed surface 15 of base plate 10 by means of doctoring blade 23 (which is actuated by reciprocating means not shown). Charges of powder 24 are thereby introduced into dispensing apertures 11 and made level with feed surface 21. Sliding plate 12 is then moved to the open position, as illustrated in FIG. 4, by hydraulic cylinder 25 so that passages 13 become aligned with their associated dispensing apertures 11 and the aliquots of powder are introduced through funnels 30 into the receivers 31 waiting below. The bulk density characteristics of the powder as introduced into the receivers do not vary substantially from those of the powder in the hopper. I
In practicing the instant invention, it is advantageous to provide receivers 31 as a plurality of properly positioned preformed blisters in an endless strip 32 of material such as polyethylene, polyvinyl chloride, sheet metal, etc. This strip 32 rests beneath funnels 30 on supporting member 33 which, in the illustrated embodiment, preferably consists of three individual supports 34, 3S and 36, positioned to form longitudinal channels 37 and 38 for the respective rows of receivers 31. Supporting member 33 is provided with leveling screws 40 to adjust its position with respect to funnels 30.
Between each cycle of the powder feeding operation, strip 32 is advanced by means of sprocket 41 engaging sprocket holes 42 to bring a new set of unfilled receivers into position beneath funnels 30 and to advance the previously filled receivers 43 out of the powder feeding device for further operations. Sprocket 41 is intermittently rotated by means not shown in timed relation with the operating cycle. If necessary, funnels 30 are disengaged from receivers 31 prior to advancing strip 32 and are then reengaged for the next cycle.
A variety of means can be provided for alternately opening and closing the lower extremity of the dispensing apertures, e.g., individual gates for each aperture mounted on the lower surface of the base plate, or a sliding plate as illustrated in the accompanying drawing. The latter means is especially preferred due to its suitability to increased production rates by increasing the number of passages therethrough cor responding to the increased number of dispensing apertures.
It is also preferred to provide a doctoring blade engaging the feed surface of the base plate as the means for drawing powder therealong and for adjusting the level of the powder in the dispensing apertures. By this single operation in combination with movement of the sliding plate between the open and closed positions, the instant device is able to deliver simultaneously to a great number of receivers the specified volume of powder without altering its bulk density.
It is a feature of the instant invention that it provides a method of feeding powder which is suited to either manual, semi-automated or fully automated operation and permits varied rate of operation without loss of efficiency. Additionally it is possible to expand the capacity of the powder feeding device as desired by increasing the number of dispensing apertures in the base plate. In contrast with other powder feeding devices, this expansion of capacity requires no increase in number of parts, either stationary or moving, nor any increase in complexity of operation.
