AUTOMATIC BEAD DISPENSING
IMPORTANT : Check that the parameters have been preset
according to the kind of REGULEX® proportioning gun.
- Display on the screen
'AUTO MODE'.
The robot has control of the REGULEX® proportioning gun.
Three functions are performed successively during the automatic mode :
Filling - Regulation - Extrusion.
Filling :
The REGULEX® chamber is filled by servo-controlling the piston raising the pressure in the chamber.
The piston reaches the Top Position (this parameter is defined depending on the bead length and
section).
During the filling, the LED is ON. When the filling is completed, the LED goes out.
Regulation :
The system regulates the pressure to reach the desired value, corresponding to the last stored flow.
When the correct pressure and position are reached, the 'READY' LED lights up.
A 'READY' signal is sent to the robot.
The REGULEX® outlet valve stays closed.
Extrusion :
The robot controls the seal extrusion.
The REGULEX® outlet valve opens. The 'EXTRUSION' LED lights up.
Dispensing of the bead.
IMPORTANT
During programming of the material bead trajectory, start the dispensing cycle of the
bead where it has the most constant diameter.
At the end of bead :
- Keep a constant bead flow rate at the end of the trajectory,
- Program a NO flow condition before passing over the bead,
- Program the outlet valve to close.
CAUTION
Before moving or disconnecting any cables connected to the REGULEX® control
unit, you must switch off the control unit.
