Systems and methods are disclosed for monitoring the productivity, operability, and safety conditions of factory machinery and particularly unitizers. The system monitors factory machines such as a unitizer in a corrugated box factory, using one or more sensors to determine whether and how efficiently the machinery is operating, to determine if any conditions of the machinery require immediate attention, and to determine if a safety violation has occurred with respect to the machinery. The system appropriately notifies a factory manager of issues that arise. In addition, the system aggregates data about past performance and safety violations and generates reports about the aggregated data to help factory managers maximize productivity of the monitored machinery. The disclosed system is particularly advantageous in that it enables improvement of the productivity of the factory as a whole.
