T-ROC, a high-quality automated box-making company based in Kansas City, built the first state-of-the-art, heavy-duty, automated box-making machine in 1995. To help companies improve their bottom lines through better shipping efficiencies and carrier costs, T-ROC needed a simple and automatic way to measure items and determine the size of boxes for their machines to make, sometimes in lot sizes of one, and capable of loading the appropriate dimensions into the board feeder and box maker. With FedEx and UPS both charging based on box size and weight, the solution needed to enable machines to make exactly the right size box and communicate information for cost-effective shipping decisions.
In partnership with T-ROC, Power Motion helped develop a made-to-measure box machine using a high-speed Mitsubishi Electric iQ-F PLC connected via RS-485 with a Banner MINI-ARRAY. Items to be packed are set on a sizing table and scanned with a mini-array scanner that feeds an iQ-F series PLC capable of high-speed calculations. The machine is controlled by an FX5 controller and 2 axes of servo communicating via RS-485 to Banner arrays. An encoder measures height, and Banner outputs connected to high-speed inputs record encoder count and communicate when no beams are blocked. A GOT interface uses the MES option to send box and material size and weight to an SQL database, where they are compared to common shipping carriers’ rates.
With an economical cost, this solution provides measurement of different part sizes to precisely determine box size, interfacing successfully with new and existing box machines. The user can quickly size boxes without manual guesswork, achieving more efficient packing and less wasted material. Sending information to the SQL database allows selection of the best carriers and shipping prices, resulting in substantial cost savings. Wireless communication from the sizer to the box machine allows for flexible placement and workflows.
