Abstract: Embodiments herein describe a DTG printing environment that uses autonomous robots to move garments between DTG processing stages (e.g., retrieval stages, pretreatment stages, printing stages, drying stages, etc.). Doing so removes the dependency of DTG printing process on the stage that consumes the most time. In one embodiment, the DTG processing stages or the autonomous robot include an actuator for moving the garment and the DTG processing stage closer together. In one embodiment, the processing stage includes a lift (e.g., an actuator) that lifts a detachable carrier from the robot on which the garment is mounted. The lift can level and rotate the detachable carrier to provide a fine alignment between the garment and the DTG processing stage. While a lift is specifically disclosed, in other embodiments, the actuator could be disposed on the robot to lift up the garment.

Abstract: Embodiments provide for a conveying system to move multiple articles from one location to another. The conveying system may use a transport device to grasp each article from an initial location, rotate the articles away from the initial locations, move the articles linearly, and rotate the articles to destination locations. Rather than moving each article one-by-one, in the embodiments described herein, the conveying system can move multiple articles simultaneously to various locations where each location may contain a different process to perform on the article. Moving multiple articles simultaneously shortens the time required to process the articles.
