Safely covering all the bases: The Sick microScan3

Dr Martin Kidman, Sick UK machinery safety specialist, FS engineer (TŰV Rheinland) explains how advances in laser scanning technology are making machinery safety systems more adaptive and responsive

simultaneously, all with easy machine integration. Reducing the number of scanners on or around a machine has also been a key technology driver, including the ability for the scanners to provide additional ‘non-safe’ accurate measurement data output for navigation on mobile vehicles. Safety laser scanners are used in both

stationary and mobile machinery for the non- contact, two-dimensional monitoring of hazardous points, protective areas, and access points. When integrated into a functional safety system, they can trigger a machine, or vehicle, to safely slow down and/or stop as soon as they detect a person, part of a body, or an unexpected obstacle inside a protective field.

Safety laser scanners for safe collaborative robot applications

If there has ever been a rapid ‘revolution’ along the road to Industry 4.0, it has surely been in the advances made in mobile automation and robotics. There

has been a huge proliferation in the type and versatility of mobile machines, such as automated guided vehicles, carts, forklifts and platforms. At the same time, the scope for industrial robots of all kinds to ‘collaborate’ with human counterparts has exploded, as well as their ability to replace humans in repetitive machine tending tasks.

S4 June 2019 | Machine Safety To support this rapid

and diverse development, safety laser scanning technology has been called upon to enable adaptive and dynamic safety systems that protect people, avoid damage and collisions, while facilitating the continuation of productive working.

Safety laser scanners have needed to offer

greater product variety, increased detection ranges and quicker response times, as well as the ability to monitor complex field sets

Investment in high-

performance safety laser scanning technologies is more than rewarded in increased productivity

A safety laser scanner is a Type 3 device according to the harmonised standard EN 61496-1. When a safety function includes a Type 3 safety laser scanner, the maximum Performance Level (PL) or Safety Integrity Level (SIL) that can be achieved is PLd (EN ISO 13849) or SIL2 (IEC 62061). Critically, investment in high-performance safety laser scanning technologies is more than rewarded in increased productivity, by avoiding costly downtime associated with

detected. Using a more responsive sensor, and one that allows several warning and protective fields to be set up, can reduce the protective space needed around a robot to allow it to slow down and stop in time as someone approaches it.

Sick’s microScan3 safety laser scanner has consistently raised the bar for performance

unnecessary stops. Faster response times are also essential if vehicles are to travel at higher speeds while still slowing and stopping safely when a person or object is
