Machine Guarding

Here, a combination of the Omron Scientific Technologies, Inc. MicroSafe light curtain and OptoFlex accessory mirrors provide four sided guarding of an automated machine used to manufacture computer disk drives.

Hydraulic Press Guarding

Here, a FlexSafe safety light curtain provides an “L” shaped optical pattern protecting machine operators from a hydraulic press. The horizontal section prevents the operator from standing between the machine hazard and the vertical section without being detected.

Stamping Machine Guarding

A single MicroSafe Flexible system provides three-sided guarding around the hazardous machine. With Omron STI's exclusive Individual Beam Indicators, installation and alignment is simple and easy.

Perimeter Guarding

The cost effective Perimeter Access provides guarding of robot centers and large automated machinery. The Omron STI OptoFlex corner mirrors direct the infrared beams to four sides of a machine.

Silicon Wafer Quality Control Stand

Full wafer trays are placed in the work cell by the operator reaching through a MicroSafe safety light curtain. Access to the hazardous robot is additionally guarded by hard guarding on three sides which has been interlocked with the MC magnetically coded safety switches. In order to assure that the robot will not start with someone in the enclosure, Omron STI Universal Safety Mats are used inside the perimeter. The hinged guard below the safety light curtain is interlocked using an HP6009 hinge-pin operated safety switch.

Process Systems Involving

Non-Electrical Hazards
Processes often involve energy sources that cannot be isolated by opening an electrical circuit. Many times pressure, chemical, or thermal hazards can be isolated by means of a valve lock. Closing the valve allows the master key to be released. The master key is inserted into a key exchange unit that then releases the door access keys.

Plastic Molding Machine

This plastic molding process presents both heat and pinch-point hazards. In order to keep personnel away from hot equipment used to melt plastic pellets, hinged hard guards are held in place by solenoid-locking safety switches which hold the guards closed until the machine control system determines that the temperature has cooled to a safe point. Additionally, personnel are protected from a point of operation hazard using an Omron STI safety light curtain.

Transfer Robot Guarding

This large industrial robot is used to transfer work in process from one conveyor to another. Moving quickly, it has the potential to seriously injure personnel. Omron STI Universal Safety Mats in conjunction with Omron STI safety mat controllers are designed to protect workers by sending a stop signal to the robot to cease hazardous motion.
