2.2 Theory of Operation
The Rotorspray 97115 is clamped in a fixture. The stationary applicator is clamped in the holder
4
of the rotorspray so that the tip of the flexible dispensing needle is directed at the inside of the
wetting holes on the rotor disc
6
.
The Loctite
®
Controller 97123 controls:
– The switching on of the rotorspray.
– The dispensing after the rated rotor speed is reached and during the preselected dispensing time.
– The switching off of the rotorspray.
As long as the stationary applicator valve is open, the product is dispersed through the wetting
holes by centrifugal force and uniformly distributed onto the cylindrical inner surface of the part.
In conjunction with an advancing slide, the dispensing is performed depending on the switching on
of the rotorspray:
– At the end of the advancing movement (bead dispensing) or
– During the advancing movement (area dispensing).
The drive assembly of the rotorspray has longitudinal play of 5 mm. Within this distance,
unintentional contact with an obstacle can be compensated without the rotor disc or the drive
assembly and its shaft being damaged. Furthermore, the drive assembly is so constructed that in
case the product flows back, the drive assembly and the rotor housing cannot glue together.
With longitudinal play and with the special construction of the drive assembly, a perfect function
is guaranteed.
When a disturbance occurs in a dispensing sequence:
– The dispensing sequence is interrupted.
– The rotorspray is switched off.
– The 97123 Controller signals a error message with a beeping tone (see Section 7).
