Every employer has a responsibility of keeping his/her workers safe especially those that operate automated machines. In connection to that many manufacturing companies ensure their devices are equipped with sensor-based safety gadgets that meet ANSI, ISA, ISO, and OSHA standards.
Below we highlight some of the technologies for automated machine safety;
Light curtain is an elongated photoelectric sensor having a transmitter and receiver. Simply standing too close to the curtain causes the proximity sensor to shut off the machine. When the spindle stops, the doors locking mechanism is released. When installing this device speed is paramount for early detection of danger; hence if the company is using a VPN, it needs to test VPN speed for prompt responses.
The use of light curtains has become popular with manufacturers in many industries because they are known to be an effective method of replacing hard guarding. You can find light curtains in automotive OEMs and Tier 1s and Tier 2s.
Depending on what needs to be detected resolution 12-14 mm detects fingers, 30mm is standard for hand detection and 100-300 mm to detect people.
A laser scanner is used to guard large danger zones that are either stationery or mobile. It is an optoelectronic device using a diffused reflection of emitted light to detect the presence of a person or object in a secured area.
Laser Scanners are generally used for large guarding applications because they are easily programmable, cost-effective and robust. The laser scanner is compact but can offer 5.5-meter scanning range and 275-degree scanning angle for an area to be guarded.
This scanner has an interactive display that provides text, graphical and diagnostic information during operation others have an in-built camera that captures images and videos when a person or object enters the protected area.
Users of this scanner include manufacturers of tires for agricultural machines, automotive and many more.
Stay In Control
SC26-2 and XS26-2 safety controllers are designed to send data to connected devices through the profinet communication protocol. Users of this device include automotive OEMs and Tier 1s, food and beverage companies and medical device manufacturers. When configured to 256 virtual status outputs, they send non-safety status signals to PLCs, light indicators and similar devices.
OMRON NX-SL5 series safety controller connects using a CIP Safety Ethernet/IP connection. It is known to be robust, compact and easily adapts to applications involving safeguarding devices.
Functional safety encoders can generate information about position, angle, and counts on mechanical and electrical safety. They are frequently used to monitor motors in conveyor and material handling systems.
In Conclusion, these technologies are more accessible and cost effective to implement and maintain. They protect workers from severe cuts, fractures, crushed organs, dislocations and amputations of body parts because of industrial accidents. Also, it reduces the risks of fines for manufacturing companies that occur when a worker is injured while on the line of duty.
Everyone planning to enter the manufacturing industry should consider investing in these devices for maximum safety of his workers.
