Electrostatic Technology, Inc Trickle Impregnation System
14 Serial #18028
6 MECHANICAL FUNCTION: SEQUENCE AND DESCRIPTION
6.1 LOAD AREA
Parts are automatically placed on a load ramp where they are cycled through a
separator and loaded onto the E.T.I. Roto-Flo Conveyor via an escapement device.
The conveyor moves parts through each station of the Trickle Impregnation System.
NOTE : The drive system is located at this station.
6.2 INDUCTION HEATER STATION
This Induction Heater is a 100 kHz/30 kW unit. The Induction Heater raises the
temperature of each part to approximately 350° F. The hood for this module must be
closed to allow the unit to operate.
Adjustment controls for the Induction Heater is located on the Operator Control
Panel. For information on temperature adjustment, refer to the Heuttinger Induction
Heater manual in the Manufacturer’s Manual Section of this Manual.
6.3 RESIN TRICKLE STATION
After the parts are heated they are conveyed through the Trickle Station. Four
pairs of resin deposition nozzles are mounted on a traverse assembly that
consists of a plate riding on a pair of shafts with ball bushings. The trickle plate
is driven by a ball screw/servo motor arrangement so that it exactly follows the
speed of the rotating armatures for 7.5 inches (3 pitches of the transport screw) to
allow time for the resin to trickle onto the parts as they rotate. The four pairs of
nozzles will trickle resin onto four (4) parts at a time for 18 seconds (6 seconds
per pitch) and then will retract to the home position. A Fiber Optic Sensor will
signal when the process is to start again.
The Trickle Station will be supplied with two 5-gallon stainless steel reservoirs
with handles, each with a pneumatically driven stirring bar, 2 peristaltic pumps
and two sets of supply tubing. This redundancy allows the Operator to continue
running while one system is being filled and/or cleaned. It also includes
stainless steel troughs and shielding around the trickle traverse assembly
designed to contain and collect un-deposited resin and return it to the reservoir.
Tubes will be adjustable in and out and feed tubes will be of a “tube within a
tube” design.
6.3.1 Resin Level Sensor
A Resin Level Sensing Unit (Ultrasonic Level Sensor) located on top of the
Resin Holding Tank will light a Blue Warning Light if there is a “LOW RESIN”
condition in the Holding Tank.
