PAC brings glue application under central control

Mecasysteme (www.meca-pac.com) of France understands this fundamental fact of the machine-building scene, and its BTM 12 tray former illustrates how the firm’s designs take ease of changeover into account.

Used primarily in the fresh produce sector, the BTM12 erects corrugated trays from flat blanks and glues them with hot melt emitted by as many as eight nozzles. Until recently, the gluing process was controlled by a module that was entirely independent from the machine’s automation system. Technical manager Philippe Ternois wanted to integrate the gluing control module into the automation system. Knowing about the integrated automation platform offered by B&R (www.br-automation.com), he decided to work with the B&R France team to find out how to integrate the gluing module and, at the same time, ensure fast, accurate, and reliable glue application.

The controls components Ternois selected for his particular application were the B&R PC-based Power Panel 220 as the central control unit together with the X2X bus and X20 IO modules. The Power Panel automation platform is a good example of what has come to be known as a “Programmable Automation Controller,” or PAC. It combines the touchscreen display of HMI, the logic of a PLC, and the motion control of a PC all in one multidisciplined controller.
