NORD Drivesystems to showcase solutions for materials handling at Drives & Controls
Published: 18 March 2016 - Rachael Morling
On Stand D526, NORD Drivesystems will showcase a large fully functional conveyor technology demonstration rig that brings together a selection of its geared motors and decentralised frequency inverters and starters. These are well proven for materials handling applications in packaging machinery and intralogistics industries such as baggage handling.
With Profibus communication and fully synchronised control across the entire multi-axis system, the demonstration rig displays the diversity of features and functions available from NORD’s electronic and mechanical drive technology. The walk-around rig includes a combination of general purpose and closed loop positioning-capable inverter controlled geared motors. These drive belt and roller conveyors linked with mechanical elevating elements that interact with machine control components such as proximity sensors and light barriers - to load, transport and stack sample crates.
For the left and right load pickup axes, NORD SI series universal worm geared motors are controlled with motor-mounted SK 135E soft starters. This decentralised configuration includes actuation via Profibus where sensors are used to monitor the position of the crates which are stopped by switching off the soft starter.
The lower roller conveyor features a high-efficiency NORDBLOC.1 bevel geared motor driven by an SK 180E frequency inverter – an economic general purpose combination for simple speed control of horizontal conveyors. With material position detected via a light barrier, directly connected to the inverter with information transmitted to the controller via Profibus.
The upper belt conveyor displays more sophisticated control with a SK 200E series inverter and NORDBLOC.1 bevel geared motor. Contactless backing up of crates via sensors directly wired to the inverter allows the stopping position of the crates to be set via the inverter over the communication bus and also handles synchronisation with the load pick-up inverter for transferring the crates into the lifting equipment.
For the elevating axes at both ends of the rig, SK 200E inverters and NORDBLOC.1 bevel geared motors fitted with a CANopen absolute encoder demonstrate the POSICON positioning option available in the range. The raising and lowering function includes a motor mounted brake and brake management on the inverter, with further external proximity switches installed on the elevators for safety purposes. Brake management is taken care of via an 180VDC output and the high overload potential is countered with a brake resistor.
NORD will also feature other smart control solutions for synchronous and induction motors along with many examples of its comprehensive range of gear units which are available for power outputs from 0.12 to 2,200 kW.
