“The line should have been taking 12 seconds to produce one part, but the machines were taking much longer. The old solution was a physical guard that took 2 additional seconds to cycle. That is why we had to find an alternative.”
Safety curtains allow operators unobstructed access without sacrificing safety. Once the light curtain is interrupted (i.e. by a person or an object), it will automatically stop the machine. “Compared to the old system, where the operator had to wait until the door closed completely before starting the cycle, the benefits are clear”.
While the Bosch Toluca plant also uses curtains made by other suppliers, Mr. Martínez noted that the difference with the KEYENCE curtains is their durability. “Although KEYENCE safety curtains operate basically like other safety curtains, we chose KEYENCE because it has a line that is suitable for heavy-duty environments. This means that we can guarantee if our operators hit, scrape, or even spill something on the curtains, they do not need to worry about causing damage and can continue working undisturbed.”
Another area of value is the service and technical support provided by a local KEYENCE specialist whenever requested. KEYENCE safety specialists offer detailed information, advice and solutions for any type of application to ensure the equipment is used in the safest and most efficient manner.
In summary, by implementing the KEYENCE GL-R series, Bosch was able to improve production efficiency while not sacrificing safety.
