INVENTORS PAUL ULICKY y BENJAMIN A. KSIONZAK United States Patent Office 3,331,057 Patented May 28, 1963 3,091,067 AUTOMATIC TABLET FILLER Paul Ulicky and Benjamin A. Ksionzak, Kenmore, N.Y., assignors to Strong-Cobb-Arner Co. Inc., Buffalo, N.Y., a corporation of New York Filed Dec. 3, 1959, Ser. No. 857,203 4 Claims. (Cl. 53-244) This invention relates to an apparatus for inserting a predetermined number of objects into suitable containers, and particularly to an apparatus for filling a predetermined number of medicinal tables into a container, such as a bottle.
In the packaging of medicinal tablets, one of the steps in the procedure is to segregate the desired number of tablets from a bulk quantity and to insert these into a suitable container, such as a glass bottle. Hitherto in the art, complex machines have been made which perform this step. One method is to provide a circular table with a plurality of holes and rotate the table over the containers dropping the tablets therein. Such machines are complex and the operator cannot tell the beginning of the cycle of filling and thus a new cycle may begin to overflow the bottles.
An object of this invention is to provide a means of filling suitable containers with a predetermined number of tablets.
Another object of this invention is to provide a means of filling suitable containers with a predetermined number of tablets which is automatic.
Still another object of this invention is to accurately fill a container with a pre-determined number of tablets and move said container to the next step.
Further objects and features of the invention will become apparent to one skilled in the art from a reading of the following description in conjunction with the accompanying drawings, in which:
FIGURE 1 is a plan view of an embodiment of this invention.
FIGURE 2 is a front view of the embodiment shown in FIGURE 1.
FIGURE 3 is a partial side view illustrating the operation of this invention.
FIGURE 4 is an enlarged sectional view of the hopper showing a form of modification.
With reference to FIGURES 1, 2, and 3, legs 11 sup- 1 port angle irons 12. Angle irons 12 form a bed or support for conveyer belt 13 as best shown in FIGURE 3. Conveyer belt 13, actuated by any suitable power means, carries suitable containers 16 to and from the apparatus. Guide rails 15, supported by supports 14, guide and hold containers 16. Guide rails 15 may be adjustable up and down supports 14 to accommodate diflerent size containers. Stops 27 allow a predetermined number of bottles to stop under filling tubes 21. Stops 27 may be of the conventional solenoid actuated type and also may be adjustable for different size containers.
Supports 18 hold hopper 20 and tray guideway 32 in place. Angle iron 17 is fastened to hopper 20 and is provided with holes to accommodate adjustable screws and nuts 19. Thus the height of the hopper above tray 23 may be varied.
Tray guideway 32 may be formed of angle iron. Glass, or any other suitable material, plate 22 is fastened to tray guideway and forms a table under hopper 20. Perforated tray 23 rests on glass plate 22 and is slidable along plate 22.
Perforations or holes 33 in perforated tray 23 are formed in equally spaced rows. The number of holes in a row parallel to guideway 32 determine the number of tablets which will fill container 16. Thus, if a row parallel to guideway 32 contains holes, 30 tablets will fill container 16. The size and number of holes 33 will accommodate any size of number of tablets which container 16 is to hold. The number of holes perpendicular to guideway 32 will determine the number of containers 16 to be filled with one operation.
Air cylinders 24 are mounted on the outside of tray guideways 32 by angle irons and bolts 26. The rods of air cylinders 24 are positioned to extend in the direction of the conveyer belt and containers. Bar 29 is connected between air cylinders 24 and fastened to perforated tray 23. Air cylinders 24 are controlled by the control 28 conveniently mounted on angle iron 12.
Air cylinders 24 move perforated tray 23 laterally over plate 22 and under hopper 20. Filling tubes 21, formed from metal tubing or any suitable tubing, are mounted over conveyor belt 13 in such a manner to allow a tablet to drop into container 16. The top of filling tubes 21 are flush with plate 22.
FIGURES l, 2, and 3 best illustrate the operation on the apparatus. When a sufiicient number of bottles 16 collect on conveyor belt 13, an operator actuates solenoid stops 27. Stops 27 allow the correct number of containers 16 to be carried by conveyer belt 13 into a position such that all containers are directly under their re spective filling tubes 21. At this point in the cycle, the tray is in a forward position. When the containers are in their respective positions, the operator actuates stops 27 which prevent the exit of containers 16 from the filling station or the entry of additional containers to the filling station.
The operator then actuates air cylinders 24 by control 28. Air cylinders 24 pull connecting bar 29 back, and hence, tray 23 follows. As tray 23 passes under hopper 20, tablets fall onto tray 23 and into perforations or holes 33. Holes 33 are just large and deep enough to hold one tablet. The height of hopper 20 may be adjusted by adjustable screw 19 so as to prevent any tablets from escaping the hopper unless they are in holes 33.
Plate 22 prevents tablets from falling to the floor. As the tray is in its backmost position, the operator again actuates air cylinders 24 which move the tray slowly to the front of the machine carrying tablets forward. As each hole 33 of tray 23 passes from the end of plate 22 to filling tubes 21, the tablets drop through filling tubes 21 into containers 16.
When tray 23 reaches its initial starting position, containers 16 contain a predetermined number of tablets corresponding to the number of holes 33 which pass over filling tubes 21. The number of filling tubes 21 corresponds to the number of containers 16 filled in one cycle. The operator now stops tray 23 by control 28 which stops air cylinders 24. The operator actuates stops 27 allowing the filled containers to be carried to the next station and empty containers 16 to enter the filling station. The cycle is now complete and ready to begin again.
FIGURE 4 shows a modification of the present invention. Hopper 20 may be provided with counter-rotating brushes 31 which are driven by a suitable means such as gears 30. Counter-rotating brushes 31 are desirable when used with uncoated tablets to help the tablets into holes 33 and prevent the escape of tablets from hopper 20 unless they are properly in holes 33.
It is to be understood that the present invention may be fully automatic, thus eliminating the operator. In such a modification solenoid stops 27 and air cylinder control 28 could be controlled by any suitable automatic timing device. With such an automatic apparatus, tray guideway 32 could be extended and another filling station complete with filling tubes 21, conveyer belt 13, and guideways 15 added. Thus, the present invention would provide a predetermined number of tablets to fill a suitfor conveying containers to and from said apparatus; a
plate secured to said frame above said conveyer system, a perforated tray slidably resting on said plate, a hopper secured to said frame above said perforated tray, and power means comprising air cylinders for sliding said tray back and forth on said plate in a direction transverse to said conveyer system.

3. A counting and packaging apparatus for dispensing a predetermined number of tablets into each of a predetermined number of containers, said apparatus comprising a frame, a conveyer system for said containers including a conveyer belt, guide rails, and stops, a plate mounted on said frame above said conveyer system, a perforated tray slidably resting on said plate having a predetermined number of holes therein, each being adapted to contain and convey a single tablet, an adjustable hopper secured to said'frame above said perforated tray and an air cylinder for sliding said tray back and :forth along said plate in a direction transverse to said conveyer belt; I
