Leuze Electronic Safe navigation in automated-guided solutions
Sensor specialist Leuze Electronic has worked with the optical sensor manufacturer Owen/Teck to develop specialised, cost-efficient custom solutions.
Leuze Electronic says it offers effective and safe, sensor solutions for continuous conveyors, high-bay storage devices and automated guided vehicles (AGVs).
An example presented recently at Logimat was Leuze's RSL 400 navigation system – a safe scanner that combines safety technology with superior measuring output in a single device, which ensures reliable AGV guarding and navigation simultaneously. According to Leuze, the navigation can also control collision-free and easily adapted routes when multiple vehicles are in use, making the system very flexible.
Another system, the OGS 600 with edge detection and control signal transmission enables flexible optical guidance. In production and storage areas, OGS 600 enables cost-efficient vehicle automation for the transportation of materials and goods.
Its compact design and its low minimum distance to the ground of 10mm means it can be integrated into flat vehicles. Models with different detection widths and response times cover a wide range of possible applications - also on tight curves and at high speeds, thereby enabling speedy and reliable object detection even under difficult conditions. This guarantees a seamless production process - man and machine are protected.
Another highlight was the company's "Smart Process Gating" (SPG) developed on the basis of its MLC 530 safety light curtains. This is a muting process that functions without the use of signal-emitting sensors won the 2019 GIT Security Award and has been nominated for the "Best of Industry AWARD 2019" presented by "MM MaschinenMarkt". "Smart Process Gating" makes muting processes for intralogistics, the automotive industry and packaging industry less expensive, simpler and safer. Previously, muting processes with muting sensors were required in order to clearly identify when transported goods are approaching a protective field at material locks and to bridge the passing of these goods through the protective field at the correct moment. As a result of the SPG method developed by Leuze electronic, signal-emitting sensors are no longer needed, which means that conveyor systems can be made more compact. The risk of misalignment or damage to the sensors is therefore eliminated as are the costs for their maintenance and servicing. Furthermore, the purchasing costs, the wiring and risk of manipulation are reduced, which increases the availability of the complete safety device. Particularly in the case of typical intralogistics applications, the height of the protective device is entirely dependent on the safety-related requirements. Synchronisation beams do not have to be taken into consideration. With SPG, the first muting signal comes from the process control (PLC), while the second is generated by the protective field itself. SPG requires a detailed knowledge of the process, so that the necessary PLC control signals are made available in the expected time window, the company explained.
