TUBING BUNDLE INSTALLATION
Typically, the tubing bundle is pulled through
the robot arm from the robot wrist side. Keep
the bundle taped except for the bundle that
will be inside the arm. Pull the tubing through
the wrist and arm, leaving about 250mm (10-
inch) of tubing sticking out the front of the
wrist plate (see Figure 6).
Fasten the cable bundle at the exit of the arm.
Push the robot spacer plate and applicator
mounting plate to the robot wrist plate aligning
the top dead center marks of the spacer plate
and robot wrist plate. Fasten using appropri-
ate screws. Installing the tubing bundle in this
fashion will increase tubing bundle life signifi-
cantly.
BUNDLE LUBRICANT
When the tubing bundle is installed, it should
be lubricated with a generous amount of lub-
ricant to increase the service life of the tubes.
A recommended lubricant is Shell Alvania EP
#02. There are other lubricants that are
available for use. Prior to using a lubricant,
insure it is silicone free, resists heat break-
down, and is compatible with the materials it
will contact. It is recommended that tubing
bundles be re-greased every six (6) months
maximum.
INTERLOCKS
The following system interlocks are required
to prevent equipment damage:
1. Bearing air should remain on at all
times and should be shut off only by
turning off the main air to the pneu-
matic control cabinet.
> When the turbine air is turned off, the tur-
bine will continue to operate or "coast down"
for about two minutes. Provisions should be
made to assure that the operator waits at least
three minutes, after shutting off the turbine air
and before shutting off the main air supply.
> The bell cup must be removed when making
flow checks. If the paint is turned on when the
bell is mounted and the turbine shaft is not
rotating, paint will enter the shaft and possibly
damage the air bearing. Material flow checks
(flow rate verification) must be made with the
bell cup off and the turbine not rotating. Nor-
mally pneumatic interlocks will not allow the
paint to trigger on when the turbine air is off.
> The high voltage and/or coating material
must never be turned on unless the bell cup is
mounted on the motor shaft and the turbine is
rotating.
