US Patent 10035661 Systems and methods for sleeve detection

A device, system, and method for detecting a covering sleeve on a container. A sleeve detection system includes a conveyor, a height profile acquisition device, and a processor in communication with the height profile acquisition device. The height profile acquisition device is configured to acquire height profiles of a tray traveling on the conveyor. The processor is configured to analyze height profiles received from the height profile acquisition device to determine a sleeve status of the tray. In some embodiments, a light gate is disposed across the conveyor and configured to detect the presence of a tray on the conveyor approaching the height profile acquisition device.
