  • Device of controlling interval of articles on belt conveyer
    Patent number: 4120393
    Abstract: A device for controlling the interval between articles on a belt conveyer which includes forming the conveyer with a plurality of spaced belts, gates beneath the belts and movable upwardly between the belts and a control device for controlling the gates to regulate the intervals between articles carried by the conveyer. gates lift the articles from the belts and periodically redeposit them on the belts in response to a signal generator resulting in the release of uniformly spaced articles. The circuit further includes an article sensor for each gate and a further emergency sensor detecting an additional article when the system is already filled to capacity causing interruption of the motion of the belts.
