Reducing case packer cost and complexity

Brenton engineers did everything they could to make a faster and simpler case packer. Creativity—and new technology—were the keys.

Drives are integrated directly with the motors outside of the control cabinet.

The task faced by Brenton Engineering was to design the next generation of its BrentonPro Series of case packers. “We asked our customers how we could improve the machine. The feedback was to make it a faster and simpler all-servo machine,” said Mike Grinager, vice president of technology for the company. “With the new design we did everything we could to reduce the complexity of the machine. We took out the pneumatics, which was the most expensive aspect of the machine, and our engineers removed more than 200 moving parts, reducing costs by one third. Plus, the integrated servo motors and drives that we now use require less space than even the smallest motors we used previously,” said Grinager.


The new BrentonPro Mach-2 case packer is an all-servo-driven, side-load case packer. It employs an IndraDrive Mi integrated motor/drive platform with Sercos distributed input/output (I/O), an IndraMotion MLC motion logic controller, and the IndraControl VEP40 human machine interface (HMI)—all from Bosch Rexroth. According to Grinager, the multi-axis machine reaches speeds of up to 25 cases per minute and can accommodate a variety of cases. Types include RSC, HSC, tray, wraparound, knock-down and harness for cartons, bottles, cans and tubs.
