Abstract
Abstract A method and apparatus for orienting rotationally symmetrical articles and containers having an orientation reference index thereon. An infeed mechanism successively delivers containers to a rotary starwheel, preferably having a plurality of container pockets spaced about its periphery. An arcuate guide is concentric with and spaced radially outwardly from the periphery of the starwheel. A mechanism is provided within each pocket to maintain the entering containers initially in a radially extended position, in rolling engagement with the arcuate guide. A detector senses the index on the rotating container, and sends a pulse to delay circuitry. Depending upon a number of operational parameters, including overall speed of the orienter, the viscosity of the product within the containers, and whether the containers are full of product or not, the control pulse is accordingly delayed. The delayed control pulse then deactivates the mechanism, radially withdrawing the container farther into the pocket against a brake shoe. The oriented containers are subsequently labelled, packaged, or otherwise processed.
