Abstract: An auto sort and label (ASL) system includes a conveyor, a controller, a sensor, and a label, print, and apply (LPA) system. The conveyor conveys articles through the ASL system. The sensor is positioned along the conveyor and identifies an article. The controller receives sensor data from the sensor. The LPA is positioned alongside the conveyor and prints labels in sequence with the corresponding article as it travels along the conveyor and applies the labels to the corresponding articles as the article passes the LPA. The controller controls the conveyor such that a gap and/or pitch between a first article and a second article is adjusted to an optimal distance to match the operation capability of the LPA. The controller verifies placement and contents of the label upon the article as defined by sensor data and accepts or rejects the labeled article for further handling based on the verification.
