Apparatus and methods for the random spin printing of capsules

Claim 2

In a capsule turning apparatus, the combination which comprises: a continuously rotatable capsule transporting cylinder having a plurality of spaced-apart capsule cavities having radially extending pocket portions arranged to receive the capsules in upstanding positions therein, means for rotating said cylinder, means providing a plurality of elongated transverse pocket portions which extend in a direction arranged generally axially with respect to said cylinder, each said transverse pocket portion intercommunicating with one of said radially extending pocket portions by way of a shaped transfer surface, and means for causing tilting movement of said capsules out of said upstanding position in said radially extending pockets and into said transverse pocket portions and thereby transferring said capsules, while said cylinder is rotating, from said radially extending pocket portions to said transverse pocket portions.

Claim 3

The apparatus defined in claim 1 wherein said radially extending pocket portions and said transverse pocket portions are portions of the same capsule cavities.

Claim 4

The apparatus defined in claim 1 wherein a conveyer means is provided under said transversely arranged pocket portions for receiving said transversely arranged capsules by gravity

Claim 5

The apparatus defined in claim 3 wherein a printing means is provided in cooperation with said conveyor means to apply printed indicia to said capsules as said capsules are forwarded on said conveyor.

Claim 6

In a capsule orienting and turning apparatus, the combination which comprises: a continuously rotatable capsule transporting cylinder having on its surface a plurality of spaced-apart pockets for the capsules, means rotating said cylinder to move said pockets arcuately from positions facing open upwardly to positions facing open downwardly, means for feeding a plurality of capsules for reception in said pockets while said pockets are open upwardly, each said pocket having an elongated pocket portion for receiving said capsule therein with the capsule axis in a first position substantially upright and perpendicular to the direction of capsule movement, and each said pocket having a laterally extending elongated pocket portion disposed generally in an axial direction with respect to said cylinder, arranged to carry the capsule disposed in a second position crosswise of the direction of its movement and also crosswise of said first position, and shifting means, operative while the capsule pockets are moving, to shift said capsule from said first position to said second position.

Claim 7

In a capsule orienting and turning apparatus, the combination which comprises: a continuously rotatable capsule transporting cylinder having on its surface a plurality of spaced-apart pockets for the capsules, means rotating said cylinder to move said pockets arcuately from positions facing open upwardly to positions facing open downwardly, means for feeding a plurality of capsules for reception in said pockets while said pockets are open upwardly, each said pocket having an elongated pocket portion for receiving said capsule therein with the capsule axis in a first position substantially upright and perpendicular to the direction of capsule movement, and each said pocket having a laterally extending elongated pocket portion disposed generally in an axial direction with respect to said cylinder, arranged to carry the capsule disposed in a second position crosswise of the direction of its movement and also crosswise of said first position, and shifting means, operative while the capsule pockets are moving, to shift said capsule from said first position to said second position.

Claim 8

The apparatus defined in claim 5 wherein said shifting means includes means forming a passage arranged to carry high velocity fluid.

Claim 9

The apparatus defined in claim 6 wherein said fluid is air.

Claim 10

In a method of printing capsules which are randomly arranged in a container, said capsules having body portions and cap portions, the steps which comprise: separating the capsules from one another, arranging them at substantially equal spacing with their axes disposed radially in an annulus, and moving them continuously along said annulus, some with caps up and some with caps down, directing a stream of air against the upper portions of all of the capsules while they are moving along said annulus to swing all said capsules to an axial direction with respect to said annulus, with the cap and body portions arranged at random, depositing said capsules in spaced arrangement on a flat, moving support with the capsule axes maintained in said axial direction, and printing upon the capsules so arranged and while moving upon said support.

Claim 11

In a method of printing capsules which are randomly arranged in a container, said capsules having body portions and cap portions, the steps which comprise: separating the capsules from one another, arranging them at substantially equal spacing with their axes disposed radially in an annulus, and moving them continuously along said annulus, some with caps up and some with caps down, directing a stream of air against the upper portions of all of the capsules while they are moving along said annulus to swing all said capsules to an axial direction with respect to said annulus, with the cap and body portions arranged at random, depositing said capsules in spaced arrangement on a flat, moving support with the capsule axes maintained in said axial direction, and printing upon the capsules so arranged and while moving upon said support.

Claim 12

In a method of printing capsules which are randomly arranged in a container, said capsules having body portions and cap portions which are of greater transverse dimension than said body portions, the steps which comprise: separating the capsules from one another, arranging them with their axes disposed radially in an annulus and moving them in a path along said annulus, turning the capsules while moving along said path to an orientation with their axes in an axial direction with respect to said annulus, containing said capsules in said path while swinging them through an arc of 180°, releasing said capsules after they have moved through said arc onto a moving support, maintaining said capsules in a rotatable condition in said axial direction on said support, and then contacting said capsules with a printing surface which is moving in the same direction but faster than the speed of movement of the capsules, thereby rotating said capsules while they are being printed.

Claim 13

In a method of printing capsules which are randomly arranged in a container, said capsules having body portions and cap portions which are of greater transverse dimension than said body portions, the steps which comprise: separating the capsules from one another, arranging them with their axes disposed radially in an annulus and moving them in a path along said annulus, turning the capsules while moving along said path to an orientation with their axes in an axial direction with respect to said annulus, containing said capsules in said path while swinging them through an arc of 180°, releasing said capsules after they have moved through said arc onto a moving support, maintaining said capsules in a rotatable condition in said axial direction on said support, and then contacting said capsules with a printing surface which is moving in the same direction but faster than the speed of movement of the capsules, thereby rotating said capsules while they are being printed.
