Reducing downtime with machine safety

Today’s manufacturers are under pressure to be more flexible, reduce downtime, increase efficiency and, above all, keep personnel safe. These efforts are complicated by yet another requirement: the successful management of external influences. These factors are difficult to predict, and when their true effects become known, effective adaptation can be a challenge. Fortunately, the right machine safety technology can help companies reduce the impact of unforeseen events and keep productivity levels high. In this white paper, we’ll examine how this works, with a focus on key features of machine safety solutions provided by Omron.

Omron helps Kerry Foods meet new safety standard

When Kerry Foods set out to meet CAN/CSA Z434 for their palletizing robot cell, it turned to Omron. Our successful solution included:

  • Full risk assessment by Omron TUV engineers to create a safe cell for palletizing robot
  • Six F3SG-RA safety light curtains with Bluetooth to allow for collaboration and movement of operators
  • G9SP safety controller and NB human-machine interface for on the spot programming
  • TL4019 safety interlock switches for swinging doors
  • Safety training seminars

There are 3 major types of machine guarding equipment:

  1. Safety Door Switches -- These are required when a  machine has a movable guard as access to the dangerous area. Monitoring the door will allow shut off the power when the guard is open or removed.
  2. Electro-sensitive protective device**(ESPE)** -- These detect a presence in their protected field and doesn't require any action from the machine operator. There are different types of devices as safety light curtains and safety scanners.
  3. Pressure-sensitive machine safeguarding products -- These include safety mats, edge, and bumpers.

Monitoring the position of a door or guard is a key element in machine safety. There are 3 major types of door switches:

  1. Tongue-operated Interlocks -- These require a dedicated tongue and can prevent easy cheating of the switch.
  2. Guard Locking Interlocks -- These prevent workers from entering in hazardous machine areas. They detect whether or not fences or doors are not opened and, if opened, stop machines before operators are injured.
  3. Non-Contact Door Switches -- This type does not utilize the mechanical operating method as opposed to the cam operated and/or tongue-actuated switches. As a result, they are unlikely to suffer from the mounting limitation compared to the other switches because of the easy positioning during installation.

CIP Safety (Common Industrial Protocol Safety) is an extension added to the CIP application layer to provide safety services on CIP-based networks such as DeviceNet and EtherNet/IP. The protocol has been developed according to IEC61508 and ISO 13849:1 and is approved by an independent Notified Body (TÜV).

CIP Safety over EtherNet/IP provides a scalable, modular, network-independent safety protocol that supports multicast messaging for faster response and ensures transmission integrity by detecting errors and allowing devices to take appropriate actions. This protocol is commonly used in systems where there is a need to integrate safety devices from different manufacturers to a single platform, like robots and encoders, to develop a safety solution while reducing wiring efforts.

A forcibly guided relay has a forced guided mechanism that prevents that normally open and normally closed contacts are closed simultaneously. This mechanical link between contact pairs is guaranteed over the whole lifetime. Thanks to this feature, it provides an easy way to design circuits with self- monitoring capabilities, according to international safety standards.
