Abstract
Abstract Capsule 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, randomly with respect to whether the cap portions are at the top or bottom, and an air jet shifts all of the capsules in a sidewise direction, with the caps and body portions at random.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
236 words
In a pharmaceutical capsule transporting apparatus of the type having a continuously rotatable capsule transporting cylinder having a plurality of elongated upstanding spaced apart pockets, each pocket having a radially extending portion arranged to receive and transport a capsule in an upstanding position therein, means for rotating the cylinder, a conveyor carrying a plurality of capsule carriers, and means for transferring capsules from the cylinder pockets to the capsule carriers, the improvement comprising: (a) a hopper having an opening therein, the opening located adjacent the capsule transporting cylinder to deliver capsules to the radially extending portion of each pocket; (b) a plurality of holes, each of which extend through inner portions of the capsule transporting cylinder into the capsule pockets; (c) a vacuum chest located adjacent to the inner surface of the cylinder and communicating with the pockets through the holes to assist in the delivery of the capsules from the hopper into the radially extending portion of each cylinder pocket in such manner that substantially an entire capsule is received in the radial portion; (d) a perpendicular portion in each pocket being connected to the radial portion by means of a curved surface, the perpendicular portion being generally perpendicularly disposed with respect to the radial portion; and (e) fluid jet means spaced close to the transport cylinder to shift the capsules from the radial portion of each pocket into the perpendicular portion of the pocket.

Claim 3
Dependent Claim
34 words
Improved apparatus as recited in claim 1 further including a rotatable brush positioned adjacent the cylinder and downstream from the hopper to straighten out any capsules that might be lying in an angular position.
Claim 4
Dependent Claim
13 words
Improved apparatus as recited in claim 1 wherein said vacuum chest is stationary.
Claim 5
Dependent Claim
52 words
Improved apparatus as recited in claim 1 wherein said means for transferring capsules from the cylinder pockets to the capsule carriers includes a source of warm air located adjacent the cylinder to assist in gravity release and transfer of the capsules from a bottom portion of the cylinder onto the capsule carriers.
Claim 6
Dependent Claim
33 words
Improved apparatus as recited in claim 4 wherein said pockets are arranged in a plurality of adjacent rows, each said row of pockets extending across said transporting cylinder in the axial direction thereof.
Claim 7
Dependent Claim
51 words
Improved apparatus as recited in claim 5 further comprising means for preventing premature falling of said capsules out of said pockets, said means being located adjacent said transporting cylinder and extending circumferentially from a location proximate to said fluid jet means to a location proximate the bottom of said transporting cylinder.
Claim 8
Dependent Claim
25 words
Improved apparatus as recited in claim 6 wherein said means for preventing premature falling of said capsules out of said pockets comprise a curved plate.
Claim 9
Dependent Claim
44 words
Improved apparatus as recited in claim 5 wherein a plurality of separate fluid jet means are provided, said fluid jet means being positioned in a row, said row disposed substantially crosswise of said transporting cylinder and in the axial direction of said transporting cylinder.
