Robot positions bank vault cash trays with high accuracy
The 5-axis VEROX robot designed for the Central Bank of Lebanon is proven to give fully automatic tray handling in bank vaults and has high security features such as a vision system to recognise the tray identification marks. A drive network supplied by Lenze allows high precision positioning for the 5-axes with easy integration from the matched drives and controllers.
Handling cash trays with high precision, the rail-mounted robot delivers the high levels of security required to handle banknotes and cash in bank vaults. The robot uses Lenze controllers, servo drives and geared motors which readily combine together to create a simple yet high-performing drive system.
The VEROX is a 5-axis robot handles trays of banknotes and cash weighing up to 50kg. It moves linearly on rails up to 30m and has a 2.5m vertical reach. Gripper arms reach out 1050mm to grasp the trays in left, central or right orientation. The trays can then be transported to a storage location or to the bank access point. VEROX is already successfully in service and there is strong interest from other European banks.
Using a Lenze drive system allowed easy integration and compact dimensions. A 3200 C DIN rail mounted controller connects by EtherCAT to servo drives of the Lenze 8400 TopLine series. These drives were developed by adding servo technology to the 8400 frequency inverters with the advantages of economy and small size. Geared servo motors with low backlash use synchronous motor technology with resolver feedback. Even with a horizontal speed of 1.5m/s, the Lenze system achieves positional accuracy of ±0.1mm. This same high level of accuracy is also achieved on the vertical and reach axes to ensure cash trays are delivered with precision.
