Product description UA05
Utilization
The axis was designed for automatic coating with powder applicators. The
axis can position the automatic powder gun in the corresponding position
for the required coating condition to the object by the corresponding axis
control unit. The gun axis is installed in a horizontal position, other
positions after consultation with Gema Switzerland GmbH only.
Depending on the design of the applicators, this unit may be used with all
types of powder coating.
Reasonably foreseeable misuse
–
Operation in rooms with gases
–
Incorrect setting of the mechanical travel distance limiters
–
Incorrect programming of the front and rear turning points
–
Use in connection with not permissible control units
–
Loading the carriage with more weight than allowed (see "Technical
Data")
–
Operation without the proper training
–
Operating the axis without the protective fence
Function
The gun axis is a feeding axis. The axis carries out a linear, oscillating
backwards and forwards motion in the horizontal direction (called U
motion), in order to adjust the gun position to the parts to be coated. The
movement sequences (travel distance and travel speed) are controlled by
the axis control unit.
During reverse motion, the gun is blown off using the integrated blow-off
device (
5 ).
The gun holders are pressed onto the carriage ( 2 ) with the fastener ( 3 ).
The carriage ( 2 ) is moved backwards and forwards on the linear guide
unit by a drive belt ( 4 ) inside the axis. The drive unit ( 1 ) and the electrical
connection are installed in the axis rear part. A pulse generator, which is
installed in the motor case, enables the exact positioning of the carriage.
The power supply is located in a separate control cabinet. One power unit
is needed for each axis.
If the power is interrupted, the motion of the carriage is stopped
momentarily.
To ensure that the gun axes cannot become a hazard during normal
operation, the axes are shielded by a protective fence that is 2.3 m high.
The fence has doors that are released by the control unit to allow
authorized technical personnel access to the axes.
