Precautions while Robot is Running 1

Installing Protective Equipment

• Workers who engage in this operation shall be install protective equipment, such as helmet, protective shoes, gloves and protective glasses.
• When treating grease, make sure to wear gloves and protective glasses to prevent the grease from adhering to skin and eyes.

Precautions for Transportation and Installation

• When transportation or installation of the robot (except robots whish is allowed to handle one person, such as light-weight robot), be sure to work two or more people. Use crane or lift to avoid excessive manual handling.
• Wire must be fixed to the hoisting bolt (eye bolt). If other than the hoisting bolt is used, it may cause a serious damage.
• Do not stay under the robot during operation.
• When moving the robot, if you hold the robot over the jacket to lift up, the jacket may slip, causing the robot to drop. Be sure to take the robot jacket off before moving the robot to another location.

Creation of Working Regulations and Assuring Worker Adherence

When entering the robot's restricted space to perform teaching or maintenance inspections, set "working regulations" for the following items and ensure workers adhere to them.

1. Operating procedures required to run the robot.
2. Robot speed when performing teaching.
3. Signaling methods to be used when more than one worker is to perform work.
4. Steps that must be taken by the worker in the event of a malfunction, according to the contents of the malfunction.
5. The necessary steps for checking release and safety of the malfunction status, in order to restart the robot after robot movement has been stopped due to activation of the emergency stop device
6. Apart from the above, any steps below necessary to prevent danger from unexpected robot movement or malfunction of the robot.
   • Display of the control panel.
   • Assuring the safety of workers performing jobs within the robot's restricted space.
   • Maintaining worker position and stance

     Position and stance that enables the worker to confirm normal robot operation and to take immediate refuge if a malfunction occurs.

   • Implementation of measures for noise prevention
   • Signaling methods for workers of related equipment
   • Types of malfunctions and how to distinguish them

Please ensure "working regulations" are appropriate to the robot type, the place of installation and to the content of the work.

Be sure to consult the opinions of related workers, engineers at the equipment manufacturer and that of a labor safety consultant when creating these "working regulations".

Display of Operation Panel

To prevent anyone other than the worker from accessing the start switch or the changeover switch by accident during operation, display something to indicate it is in operation on the operation panel or teach pendant. Take any other steps as appropriate, such as locking the cover.

Safety Installation and Operation of the Hand (end-effector)

When install or operate the hand(end-effector), make sure that power loss, changes of air or power supply do not cause hazardous conditions. Also, please be aware that residual energy might exist inside the device.

Ensuring Safety of Workers Performing Jobs Within the Robot's Restricted Space

When performing jobs within the robot's restricted space, take any of the following steps to ensure that robot operation can be stopped immediately upon a malfunction.

1. Ensure an overseer is placed in a position outside the robot's restricted space and one in which he/she can see all robot movements, and that he/she is devoted solely to that task.
   • An emergency stop device should be activated immediately upon a malfunction.
   • Do not permit anyone other than the worker engaged for that job to enter the robot's restricted space.
2. Ensure a worker within the robot's restricted space carries the portable emergency stop switch so he/she can press it (the emergency button on the teach pendant or mini-pendant) immediately if it should be necessary to do so.

When the optional robot protective jacket for food processing is used, be sure to turn off the robot controller before entering the robot workable space for putting the robot jacket on, taking it off, cleaning, or checking for any dirt.

Inspections Before Commencing Work Such as Teaching

Before starting work such as teaching, inspect the following items, carry out any repairs immediately upon detection of a malfunction and perform any other necessary measures.

1. Check for any damage to the sheath or cover of the external wiring or to the external devices.
2. Check that the robot is functioning normally or not (any unusual noise or vibration during operation).
3. Check the functioning of the emergency stop device.
4. Check there is no leakage of air or oil from any pipes.
5. Check there are no obstructive objects in or near the robot's restricted space.
6. In case of emergencies, worker shall carry emergency stop switches (for teach pendant and mini-pendant, emergency stop buttons) to be able to press immediately.
7. Make sure that no one exists inside the safety fence except for who engages operation.
