Abstract
Abstract A bottle-spotting device which rotates a bottle about its vertical longitudinal axis as it is conveyed along a conveyor path and engages a spot on the bottle to precisely orient that bottle. Friction rails on one side of the conveyor path cooperate with pusher elements mounted on a pair of endless chains on the opposite side of the conveyor path to impart rotation to the bottle. A bottle-spotting lug is mounted on one of the endless chains and is adapted to engage the spot on the bottle and stop rotation once the bottle has rotated to the desired position. A star wheel is used to feed the bottles into the spotting device at a metered rate. A switching circuit is provided for starting the spotting operation only when a predetermined number of bottles are ready for a spotting operation.
