Muting system is sensible about access

An Omron Scientific Technologies product story

The IMS safety muting system easily integrates into nearly any entrance and exit conveyor system application, and is engineered to distinguish between materials and people entering a dangerous area.

The IMS safety muting system easily integrates into nearly any entrance and exit conveyor system application, and is engineered to distinguish between materials and people entering a dangerous area.

This differentiation is achieved by arranging the muting sensors such that only a very particular combination of signals triggered by incoming material allows the system to enter a safety-muted state.

In the past, several components were required to create a safety barrier that would differentiate material from people.

Additionally, these systems required complex wiring and programming.

The IMS provides all of the necessary components in a single package, wired and assembled on a robust platform for easy installation and use.

With the IMS, an immediate machine stop is triggered if the proper sensor sequence or combination does not occur, eg if a person has entered the access area.

If, however, a product is passing by on a conveyor, the system detects this without interrupting the workflow by muting, or temporarily inhibiting the operation of the safety system so that manufacturing operations continue normally.

For example, in packaging lines where a conveyor carries palletised loads into or out of packaging machines, the pallet must be allowed free flow into and away from the packaging machine area.

Personnel are blocked from the entry and exit points of the danger area as the pallet is conveyed to and from the machine.

However, during nonhazardous times of operation the entrance and exit are freely accessible to fork lift trucks and other personnel.
