Hipak 2675/2670 Calibration procedure
As with any electro-mechanical machine, the electronics and mechanics have to be synchronised to
gain maximum performance and accuracy.
The following are instructions for calibrating a Hipak machine with ‘Generation 7’ touch screen
control system. This should normally only be carried out when the machine is first built but,
following servicing, repairs or software upgrades, some further calibration may become necessary.
Calibrating box sizes should always be carried out in the following order:
1.
‘Encoder Setup’ – Set panel sizes but ignore panel 1.
2.
‘Offset – Blade to Sensor 2’ – Set panel 1.
To enter ‘Engineering Setup’ screen:
Select ‘Configure System’, ‘Engineering Parameters’ and Enter Password………
‘Running Parameters’
Running Speed – This shows the speed selected by the operator from the
‘Run’ screen.
Jog Speed – This shows the speed selected by the operator from the ‘Manual
Jog’ screen.
Offset Distance – This is the distance in mm from main blade to sensor 2. Adjusting this offset will
change the length of the first panel of each box.
Nominal setting is 75mm. A larger offset will give a longer first panel.
Number of Boxes to Service – This is set to remind the operator when a service is due.
When the system boots up the screen will show ‘Service Due at……’. The set number will reduce
by the number of boxes made until, at zero, the screen will show ‘Service Due’. Nominal setting is
500,000 which is the average production for six months.
The ‘Service Complete’ button should be pressed, after servicing, to reset.
Move Adjustment Percentage – This is used to set the ratio of the linear movement of the corrugated
board to the number of turns of the motor, which affects the last panel of a box. Under normal
conditions the board travel is monitored by both the surface encoder and the motor encoder with
constant comparisons and corrections electronically. When a box is made with a glue flap of less
than 50mm, the last panel is measured only by the motor encoder and so this has to be calibrated
correctly to take account of any tolerances in the manufacturing process of the knurled roller or
pulleys.
Nominal setting is 0.0. A positive setting will give a longer panel. Negative will be shorter.
