2012-10-16 - Demos to highlight systems that respond to the food manufacturing and packaging industry’s demand for increased machine safety
ABB Jokab Safety, a leading supplier of machine safety equipment, will exhibit an array of electronic safety components and mechanical interlock switches at Pack Expo 2012, October 28-31 at McCormick Place in Chicago (Booth # N-4533). The ABB Jokab display will highlight innovatively designed safety systems that respond to the increasing demand from the food manufacturing and packaging industry for highly effective, failsafe safety measures. “While the food industry is rightfully calling for the highest levels of machine safety, they also seek increased diagnostics and flexible systems that are easy to operate,” said Lloyd Sinnott, business development manager for ABB Jokab Safety. “Jokab’s enhanced visual and electronic device feedback delivers easy diagnosis and increased uptime, and the increased connectivity allows for easier assembly and maintenance.” The highlights of the Jokab exhibit include:
Eden Non-Contact Safety Sensors
Eden — Adam and Eva — is a non-contact safety sensor for use on interlocked gates and hatches. The non-magnetic, non-contact closure technology provides for the highest levels of safety, with built in diagnostics and quick disconnect. The maximum sensing distance between Adam and Eva is currently 15 mm ± 2 mm. Up to 30 Eden Safety Sensors can be connected in series and still achieve the same safety level in the safety circuit. It is also possible to connect safety light beams and E-stops in the same safety circuit. The Eden sensor surpasses traditional interlock methods, providing value to OEMs and end-users alike. The Eden E encapsulated IP67K version is available for even the harshest environments.
The small modular illuminated emergency stop system, developed to fulfill the need for a small and easy to install E-stop, features built-in diagnostic information in a ready-to-mount package. The size of the device makes it possible to be installed wherever needed; and with M12 connections or cable and centralized mounting holes, Smile is very easy to install, especially on aluminum extrusions. Quick connect cabling increases value to both OEMs and end users by decreasing installation time, and providing operators system status feedback at-a-glance.
Designed with packaging and food processing markets in mind, the new generation of mechanical and magnetic interlock switches offers more flexible mounting and increased ranges, giving value to the OEM when deciding how to mount. Food grade stainless steel switches available in many footprints provide flexible solutions for the packaging and food and beverage marketplace.
Pluto Safety PLC
Pluto is an “all-supervisor” system in which the inputs and other information are shared via the databus, providing simplified design and the highest level of safety. The key difference between Pluto and conventional safety PLCs is that there is no "supervisor-subordinate" relationship between the units connected to the safety bus. Each Pluto is a “supervisor” unit and can see the other Pluto’s inputs and outputs, thereby able to make decisions about its own safety environment. Several safety sensors can be connected to one input while still achieving the upmost safety. The flexible scalable modular design allows the system designer many options when creating the blueprint for the safety system.
