RollerDrive control

Wilmington, N.C. — Interroll Corporation has partnered with Holjeron to develop a new series of intelligent RollerDrive control products that utilize Interroll’s high-quality RollerDrives and Holjeron’s innovative sensorless ZonelinkÒ Low Pressure Accumulation (LPA) control module. The result is a conveyor system that provides enhanced control capability, improved diagnostics with a lower installed cost. The LPA concept allows for low pressure accumulation, eliminating the added cost of external sensors and the associated installation components.

“To meet the growing demands of intelligent conveying systems, we have combined the best technologies of two of the major players in motorized driven rollers, Interroll’s RollerDrive and Holjeron’s Zonelink. This creates a superior MDR system that is a proficient alternative to today’s existing conveyor technologies,” said Ken Bobick, Product Manager for the RollerDrive at Interroll.
The ZoneLink-based Powered Roller Controller (PRC) senses the presence of a load by measuring current drawn by the RollerDrive. This enables the ZoneLink LPA to control downstream and upstream zones in a low pressure accumulating fashion. Each unit of the motorized driven roller system provides an input for a sensor for entry and exit control, a driver for the motorized driven roller, and two (2) RJ-45 ports for connecting to adjacent zones. ZoneLink PRC’s can be configured to run in single accumulation or train mode, and can also be manually controlled through the ZoneLink serial port.

Interroll’s HTBL RollerDrives reduce noise emissions to as low as 50 dBA when the RollerDrive is mounted in the structural frames, making it the quietest MDR in the industry. The RollerDrive HTBL can move up to 500 pounds with speeds ranging to 250 feet per minute.

The combination of Interroll RollerDrive and Holjeron ZoneLink controls will offer yet another alternative with improved capability to address the increasing demands for MDR solutions in any material handling application where accumulation or general transport is required, including postal and parcel distribution, warehouse conveying and order picking, distribution centers, packaging, and the pharmaceutical industry.
