5.3 CHECKING OPERATION
(References in figure 6.1)
The instructions for setting the operating parameters, stated in this paragraph, are given in the Instructions B manual.
CONDITIONS
- Machine on
PROCEDURE
The operations described in this paragraph serve to check machine operation before starting the production run.
- Turn the mode selector (19-23) on the control panel to SET-UP.
- Open the guards of the forming unit and turn the handwheel for manual movements.
- Make sure there are no obstructions by allowing the forming drum to complete at least one full turn.
- Close the guards of the forming unit and turn the mode selector on the control panel to MAN.
- Press button 2 to start the temperature regulator for the extruder and dies.
- Make sure the coolant does not leak in any part of the machine (extruder, metering pump, forming unit, hydraulic
power unit).
The pre-set temperatures are related to the inert plastic compound fed to the extruder before the conveyor. The
temperatures flash on the “HEAT SYSTEM” page of the control unit.
- Make sure the charge pressure of the hydraulic accumulators is correct (low pressure = 2.5 MPa = high pressure =
9.0 MPa - actuator return circuit = 1.5 MPa).
- Start the hydraulic power unit by pressing key 8.
- Activate the high pressure circuit with key 10.
All the actuators will move up except for those found near the control cams for the hydraulic valves.
- Make sure the pressure in the high pressure circuit corresponds to that required as stated on the “Data Sheet”.
- Activate the low pressure circuit with key 16 and inactivate the shut-off system for the actuator drive circuit by using
key 11.
- Make sure the pressures in the low pressure circuit and actuator return circuit are as prescribed (see “Data sheet”).
- Make sure there are no oil leaks.
- Set the speed of the main motor to about 20% (see Instructions B).
- Start the main motor with key 3 and make sure the actuators run correctly while the drum is turning.
- Increase the speed until the desired production output (caps/min.) is reached.
- Make sure the actuators operate properly by referring to the control unit display and adjust the flow rate of the low
and high pressure circuits (see “Data Sheet”).
- Inactivate the high pressure circuits (key 10) and actuators (key 11).
- Wait until all the actuators have moved down and stop the forming unit (key 7)
- Inactivate the hydraulic power unit by pressing key 12.
- When the temperatures stop flashing on the “HEAT SYSTEM” page of the control unit display, start the plasticization
unit by using key 9.
- Make sure the extruder and metering pump can turn freely.
- Inactivate the plasticization unit by using key 13.
