6.2 handling warning

If the user doesn’t operate the machines properly or the machine doesn't work normally, the

system will give the hint of , which shows that something is going wrongly. Then,
Click the prompt into alarm interface which will display concrete alarm content, the
warning relieves and the alarm prompt will disappear.
The common contents of warning generally fall into the following types:
●Operation movement is insufficient.
When the machine woks smoothly, if one valve doesn’t work or works overtime
(exceed 3 seconds), the machine will stop working and system will give the
warning of insufficient movement of operation.
Solutions: 1: See from the state displaying interfaces to check whether the body of
valve gives off output signals.
2: Check whether the pressure is normal.
3: check whether the magnetic switch for detecting position is in it place, and
whether it works well.
●Servo driver Warning
When the screen interface prompts that the warning comes from servo driver, observe the
sign displayed on the servo driver panel firstly to find out the concrete cause.
The common cases of servo driver warning are:

● Synchronous signal warning
When the machinery works normally, as servo goes forward for one time, the chain
should stop correctly at the original position and the synchronized signal of bottle
blowing should detect the target accurately. If there is no signal, the system will give
warning.
Warning indicates: 1. synchronous magic eye of bottle blowing is off the ball
2. Chain blocking
3. Failing to detect every bearing that passes.
7. Test signal calibration
7.1 blowing simultaneously with the blowing test
With the use of two detection switches, identify whether the mold is in the blank tube
or not and judge mold which number mold is entered.
Prerequisite: the machine must be in original location
Requirements:
1,.To guarantee the signal you should get the blowing machine to the first left one of
the heating group.
2. Ensure detection switch can detect each of the chain bearing accurately.
1. At this time, blowing electric eye detected the middle of the first two sets of
heating, and air.
2. Ensure that the blowing test can accurately detect every blank tube.

are tight enough, setting parts are in the right position, etc. 
1.1.2 Oiling to the wrinkled part and places need to oiling, especially to the eight
linear bearings for opening and closing moulds.
1.1.3Checking with safety gate and switch: make sure all the gates are in good
condition. Make sure if the limit switch of safety gate is running correctly by showing
of the delays. Check all the emergency switches are running well.
1.1.4 Open the valve under air loop and air filter, then push out water and foreign
matter.
1.1.5 The power of accessories should be go through before main machine in
principle. After the power of accessories is on, check the running condition and
initialization of all accessories (tem. etc).
1.1.6 Running conditions and supplying efficiency to main machine (water, air,
etc), play important roles in running of main machine. Besides opening, please check
if these machines are in good conditions when running.
1.1.7 There are differences on installing of accessory machines, according to the
different specifications supplied by the suppliers. For detailed information, please
refer to the constructions of the machine. The main points to the following items,
Cooling water: check the tem. and flux of the cooling water;
Compressor: check the pressure and volume of the air supplied to the extrusion
machine. There are two systems, high/low pressure;
Water chiller (if used): check the tem. and flux of the water.
The above loops must not leak.
1.1.8 By manual maintaining, check whether the running of bottom base and

63
dying assembly of extrusion moulds are well or not.
1.1.9 Check if the faces of moulds are in good condition in visual observation.
Make sure there is no dewing, rust, foreign matter.
1.1.10 Check if springs parts of machines of the mould guide rail are in good
condition.
1.1.11 Check the initialization of heating machine and check if the machine is
running well.
1.2. Daily checking items (when running)
The checking items when the machine is running
1.2.1. Check the pressure of working air and blowing air. If the air pressure
changes, the running of machine and blowing result will be affected. In this situation,
we can check if air supplying, air tank or filter machine are working well.
1.2.2. Check if there are abnormal sounds and librations at each part of the
running machines.
1.2.3. Do eye survey to the working condition of cylinder (driving devices).
1.2.4. Do eye survey to the working condition of perform, as well as the bottles’
carrying, supplying and fetching part.
1.2.5. Do eye survey to the working condition of servo motors. (transport part for
blowing)
1.3. Running finished
After a day or a week’s working, when running finished, please clean up each
part of the machine and its surroundings. This will avoid many potential problems. If
you have any problem or question, please check immediately.
1.4. Weekly checking items
The following items need to be checked every week. Do shut the power when
checking.
1.4.1. Add lubricant to the machines
Refer to the manual.
1.4.2. Die devices of blowing moulds
Check if the install of extension rod is tight enough. If the front of extension rod

64
out of shape or broken, it will affect bottle shaping. If necessary, change the parts.
1.4.3 Checking the heating machine
Check if there are breakages on the quartz heating machine, if the wire of heating
machine is ok. Check if the screws are tight enough, if there are broken wires. Clean
up the deflection plate. The dirt will cause bad heated perform and damage of heating
machine and deflection plate.
1.4.4 Check the installation of the moulds and machines. Check if the screws are
tightly put.
1.4.5 Clean up all the parts of the moulds. Check if there are damages and
deformations.
1.5. Monthly checking items
The following items need to be checked every month. Do shut the power when
checking.
1.5.1 Check the screw and nut of moved part and installation screw of moulds’
part. Check they are tight enough. In order to know the situation of screw as soon as
possible, please mark the screw place in paint. When find laxation, screw it down at
once and make the same mark.
1.5.2 Check and clean up every silencers of air loop. If the jam cannot be
removed after cleaning up, then change parts. If parts are not changed, the running
condition of air machines is likely to be undesirable.
1.5.3 Checking the assorted pipes
Check if the interface leaks air and if the parts are broken. Check if surfaces of
assorted pipes are broken, crooked or cracked.
1.5.4 Add grease lubricant to interface of moulds.
