    Trends in machine safety: From hardware to software

    In automation technology and in mechanical engineering, functions are increasingly being shifted from hardware to software. This also applies to machinery safety. Aside from software-based safety concepts, however, classical safety devices are still being employed – though these have new mechanical and sensor combinations. As a provider of systems and solutions for machine safety,Schmersal thereby offers everything from one

  • Door shut for cool processes

    Solenoid interlock in a deep freeze system for blood plasma

    The doors of a plate freezer which, through contact cooling, cool down freshly obtained blood plasma to a core temperature of -30°C in no time are monitored reliably with Solenoid interlocks from Schmersal. In this case, the safety switchgear units serve not so much as a means of personal protection but process safety instead.

    Safety for intralogistics

    Based in Ludwigsburg, Weinmüller Formen- und Werkzeugbau, develops and makes moulds for complex components made from pressure cast aluminium, such as transmission casings, oil sumps and engine parts. The precision moulds weigh more than 50 t – and even larger units are being called for. Alongside this is the rising demand for pressure cast tools. The heart of the system is a position switch with safety function from the new PS 116 series that Schmersal presented last year.

  • Rewriting the rules for machine safety

    What will the new Operational Safety Ordinance change?

    The new version of the German Operational Safety Ordinance (BetrSichV) will mean machine operators will need to gear up to changes in the rules on machine and plant safety. These include the obligation to check safety gear regularly and adapt it to the
    state-of-the-art where necessary.

  • To good cooperation between people and robots

    Safety Services - even for virtual safety fences

    Until now, the rule in automated production was that the working areas of people and robots are strictly separated and robots carry out their work behind safety fences. This rule is increasingly being broken, and for a good reason. When people and robots work together, both can contribute their own strengths - people have intelligence, judgement and flexibility, robots have power and untiring performance when lifting and moving loads.

  • Hold closed doors and flaps

    Hygiene-relevant safety technology in dairy product packaging

    The bottling, filling and packaging of dairy products is a sophisticated undertaking. The processing of food products such as milk and yoghurt etc places the most demanding requirements on hygiene. At the same time though, flexibility is required to reflect faster product cycle turnarounds and the importance of packaging as a marketing Instrument in the sector. With the Combiseptic 81, Gasti has developed an unusually adaptable cup filling and sealing machine with which innovative product ideas can be realised. Schmersal has contributed here with its safety technology which is just as flexible as it is hygienic.

  • Two new standards

    DIN EN ISO 14119 and the Operational Safety Ordinance

    In April and June 2015 the transition periods for two new German regulations on machine safety end. The standard DIN EN ISO 14119 is directed at the (electrical) designers and describes the
    design of guards and the choice of safety switches and interlocks, while the new Operational Safety Ordinance (BetrSichV) is intended more for the owners. Both emphasise the importance of tampering protection.

  • „Safety Services“ at work

    Machine owners must ensure the safety of the plant and machinery used by their employees.

    A “siting” in the sense of a uniform safety-relevant evaluation with the aim of identifyingweak points can be useful here. This gives owners the peace of mind of knowing their machines comply with current standards and regulations and that their employees can work safely with them.

  • Outwitting the protection system

    It’s a fact that protective equipment for plant and machinery is regularly tampered within factories.

    This is because it often hinders people’s jobs. Hence the designer must make surehis design reduces the risk of tampering. There are numerous methods available to him which he can and must use.
