Abstract
A food product stacker includes a support moveable between a support position and a release position. A machine vision system includes an imaging device and a processor. The imaging device has a field of view encompassing the support platform and is configured to capture an image of the substrate supporting the food product on the support platform, to process the image and determine a position of the substrate on the support platform, and to provide an offset output signal corresponding to the position of the substrate on the support platform. A stacking conveyor is positioned support and is configured to receive the substrate and food product when the support is moved to the release position. The stacking conveyor is moveable in response to the offset output signal. Methods of stacking substrates supporting a food product are also provided.
