ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to tablet filler devices having enhanced quality control features. These tablet filler devices include a starwheel for filling which relies upon a stepper, tablet counting motor, tablet inspection mechanisms, unacceptable tablet ejection, counting confirmation sensors and closed system filling stations. These devices have high speed qualities, quality control redundancies and fool-proof aspects at the filling stations.
2. Information Disclosure Statement
The following patents are representative of the state of the art of filler devices:
U.S. Pat. No. 3,871,295 describes a capsule orienting and turning apparatus and method for use in a spin printing procedure in which a printing roll moves at a greater speed than the capsule, thus causing the capsule to rotate about its own axis while it is being printed. Many capsules, randomly arranged in a hopper, are picked up in a rotary conveyor which arranges them first in vertical arrangement relative to the path of movement of the conveyor, some capsules upright and some inverted, and an air jet shifts the body portions of the upright capsules in the machine direction so that the cap portions can subsequently be shifted in a sideways direction by a subsequent sideward-directed air jet. Those capsules which are inverted are not affected by the first air jet because of a barrier which prevents their movement; the cap portions of these inverted capsules are blown sideways by the sidewardly directed air stream. In this way, the positions of the capsules are rectified, with all of the cap portions on one side of the predetermined path and all of the body portions on the other side of the predetermined path.
U.S. Pat. No. 3,889,591 describes a branding machine for automatically printing indicia on tablets, pills, candies or any other products of any similar shape and/or size, which comprises a hopper unit, a feed unit including at least one rotary drum having the periphery formed with a plurality of radially inwardly recessed receptacles arranged in at least one row and a printer unit. The receptacles are successively communicated with a vacuum source for receiving the products therein under suction at first, then with a source of compressed air for posture correction of said products within the associated receptacles, again with the vacuum source for holding the posture-corrected products in a definite posture thereby to enable them to be printed by the printing unit, and finally with the compressed air source for successively ejecting the printed products on to a subsequent processing station. A method for reproduction of the indicia on the products.
U.S. Pat. No. 3,925,960 describes a machine for filling containers with discrete articles comprising a series of elongated slat members movable in a closed path, a portion of the slat members having an outer surface with a multiplicity of spaced apart cavities therein. The path comprises spaced apart cavity charging and discharging stations. Means at the charging station deposit articles in the cavities. The slat outer surfaces tilt at the discharge station for the simultaneous discharging of articles. Container delivery means continuously feed containers at a predetermined uniform speed along a line parallel to the direction of elongation of the slat members and below the level of slat members at the discharge station. A first set of stationary article-guiding chutes is disposed in side-by-side relation at said discharge station, each chute having an upper inlet and tapering to a narrowed outlet. A second set of chutes is supported for movement in a closed path, each chute being generally vertically disposed and having an upper inlet wider in the direction of chute travel than any first set chute outlet and a lower outlet smaller than its inlet. The closed chute path includes a portion extending the full length of the slat members with chutes in that path portion aligned with the container feeding line and the first set chute outlets. Drive means are provided for driving the container delivery means, for driving the chutes such that each chute moves with its outlet aligned with a moving container, and for driving the slat members.
U.S. Pat. No. 4,231,462 describes a turning and orienting apparatus of the type adapted to transport capsules in a plurality of pockets or the like, which pockets are formed in a continuously moveable transport conveyor, and wherein said apparatus is further adapted to rectify the capsules, which have body portions and cap portions of greater transverse dimensions than the body portions, and wherein a vacuum is provided to shift the capsules into the desired rectified position, a capsule portioning guide is provided to retain each capsule in its pocket immediately prior to its being subject to the vacuum. The capsule positioning guide then releases the capsule as it subjected to the vacuum. In a preferred embodiment of the invention, the capsule position is pivotally mounted adjacent the capsule transport conveyor so that it can be easily moved out of its operative condition adjacent the transport conveyor for easy cleaning thereof.
U.S. Pat. No. 4,377,971 describes an apparatus which is disclosed which transports and rectifies objects, such as pharmaceutical capsules, and prints appropriate indicia on the objects. The apparatus comprises a two-drum system, the first drum being used to shift objects from a radial to a longitudinal position, and then to reorient some of the capsule so that, when the capsules are delivered to a second drum, the cam drum, all capsules are pointing in the same direction. The system takes advantage of gravity for rectification. Spin printing means are provided to print indicia on the rectified objects, as the objects travel along the periphery of the cam drum. A process for operating the apparatus is disclosed.
U.S. Pat. No. 4,394,933 describes a capsule orienting apparatus in which misoriented asymmetric capsule inadvertently passed by a rectifying unit are segregated from properly oriented capsules. Capsules are delivered by a rectifying drum to capsules carrying pockets in a segregating drum which have recessed portions sized to loosely receive properly oriented capsules and tightly receive misoriented capsules. As the loosely held, properly oriented capsules pass a discharge point, they are released. The tightly held, misoriented capsules remain in the segregating drum past the discharge point and are ejected from the segregating drum downstream from the discharge point.
U.S. Pat. No. 4,582,201 describes a product transporting apparatus for transporting solid products of generally similar shape and/or size successively from a take-in station towards a take-out station, which has first and second rotary drums rotatable in the opposite directions to each other. The first and second rotary drums are of identical construction each having at least one circumferentially row of tubular receptacles protruding radially outwardly from the outer periphery of the respective drum and circumferentially equally spaced from each other. The products can be successively supplied onto the first rotary drum and held by suction in position on the tubular receptacles then communicated with a vacuum source at the take-in station, which are in turn transported, during the rotation of the drums, to the transfer station where they are released from the receptacles on the first drum then communicated with a compressed air source, onto the respective tubular receptacles on the drum then communicated with the vacuum source. The products so transferred onto the secondary drum are then transported in a similar fashion towards the take-out station where they are successively released from the second rotary drum onto a subsequent processing station.
U.S. Pat. No. 4,619,360 describes a product transporting apparatus for transporting solid products of generally similar shape and/or size successively from a take-in station towards a take-out station, which comprises first and second ro
