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 tub-
ing 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 appropriate screws. Install-
ing the tubing bundle in this fashion will increase
tubing bundle life significantly.
Figure 6: Tubing Bundle Installation
BUNDLE LUBRICANT
When the tubing bundle is installed, it should be
lubricated with a generous amount of lubricant to
increase the service life of the tubes. A recom-
mended 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 breakdown, 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 mainair
to the pneumatic control cabinet.
> When the turbine air is turned off, the
turbine 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. Normally pneumatic interlocks
will not allow the paint to trigger on when the
turbine air is off.
