Liebherr-Verzahntechnik GmbH has further developed its rotary loading system (RLS) for automated and order-specific machine loading. It features an additional load category for transportation weights up to 2,000 kg, greater storage density, and wider interference diameters.
The RLS consists of a round storage shelf, lift module, set-up station, and optional storage tower. It operates as a transportation and storage system upstream of the workpiece machining process and guides workpieces into the machining process automatically. It can automate up to two machining centers, can be flexibly configured, and offers a high storage density with minimal footprint. This makes it economically suitable for automated manufacturing.
The RLS system architecture is based on a modular platform. All of the platform's basic modules can be individually configured for the required load category so the RLS can be precisely tailored to the appropriate production environment. The lift module loads components fully automatically into the storage shelf, which is available with two to four levels. The manufacturer-independent design also enables the system to connect to a wide range of machining centers.
What is new is an additional size capable of carrying a transportation load of up to 2,000 kg, adding an additional weight category to the 800 and 1,500 kg variants already available. This enables larger and heavier workpieces to be efficiently integrated into the automated manufacturing process. The maximum interference diameters have also been expanded from 900 to 1,400 mm so the system can be optimally adjusted to the workpiece spectrum.
The ergonomic, modular designed set-up station has been completely revised. It offers options with manual or electrical rotary units and clamping hydraulics can be integrated, presenting the new opportunity to position workpieces right on the set-up station using a precision bearing. This was previously only possible on freely positionable set-up stations, but the function is now available on enclosed set-up stations as well.
The reason for this enhancement is the growing demand from customers whose machines now machine larger and heavier workpieces with higher dimensions. This demand did not require a new design, but involved maximizing the advantages to the customer by optimizing use of space and higher transportation weights. The aim is to reduce production costs and be able to respond to market fluctuations quickly while simultaneously offering ease of operation, process reliability, and quality.
The RLS remains manufacturer independent and, as before, can be combined with diverse machining centers.
