4.2 Essential precautions for the linear conveyor module
The linear conveyor module is a YAMAHA robot so safety measures must be followed and safety equipment
must be installed just as required for other YAMAHA robots.
This section describes essential precautions for handling the linear conveyor module. Precautions for each
stage in the robot life cycle are listed from the next section, so be sure to read the whole section of “Safety
Instruction” in this manual.
Slider ejection 1.
w
DANGER
The slider and workpieces ejected at high SPEED from the linear conveyor module may strike persons, causing
serious and POSSIBLY fatal injuries. Please comply with the following points.
• Do not enter or allow the face and hands to intrude anywhere along the line where the linear conveyor guide
rail may extend (not only ejection side of the conveyor but also the insertion side).
• If ejecting the slider on the linear conveyor, then install a suitable ejection mechanism (device to catch and
stop the ejected slider).
• Install a structure and a mechanism to catch and retain the slider on the side where the slider is inserted.
• Install a safety enclosure outside the linear conveyor movement range. Design the safety enclosure so that the
slider and workpieces from the linear conveyor are not ejected outside of the enclosure.
Preventing electrical shock 2.
w
DANGER
Always comply with the instructions in this manual when installing, operating and inspecting the linear conveyor
module. Failure to do so may lead to electrical shock, serious injury or even death. Please comply with the
following items:
• Read and FOLLOW the instructions in this manual when grounding the linear conveyor module and installing
the termination module.
• Do not touch the motor of the linear conveyor module when it is on.
• Always comply with the instructions in the manual when performing maintenance and be sure to turn off the
power before starting maintenance tasks.
• If cracked or broken plastic motor parts are found, stop using the linear conveyor module immediately and
turn off the power.
Strong magnetic field 3.
w
WARNING
The linear conveyor module contains powerful permanent magnets and electromagnets that generate strong
magnetic fields. Always comply with the precautions listed in this manual when using the linear conveyor
module. Those persons wearing medical electronic devices such as cardiac pacemakers or hearing aids are at
particular risk of major injury or even death.
• Always attach the magnet protective cover (supplied) when handling, shipping or storing the slider when
removing it from the linear conveyor module’s guide rails.
• Do not approach the motor of the linear conveyor module while the power is on. (Stay at least 100mm away.)
• Do not attempt to disassemble the linear conveyor module (including surrounding covers).
• Do not place any tools near the slider magnets and the linear conveyor motor while the power is on.
High temperature hazard 4.
w
WARNING
The motor for the linear conveyor module is mounted on the module, and so it is easy to come into contact with.
To allow heat generated during operation to DISSIPATE, install the module on a base made from good heat
conducting material such as metal.
The motor reaches high temperatures during and IMMEDIATELY after operation, so touching it at those times may
cause burns.
Before touching the motor, first turn off the controller power, then wait a while and check that the temperature
has DROPPED sufficiently.
