Possible causes:

  • Check the blank cutting tolerances and blank squareness.
  • Adjust the rollformer (roller shaft clearance and spring pressure) according to the manual.
  • Control if there is a high difference in the tin plate hardness, by rollforming 10 bodies without welding. Put them on the floor in line and compare the difference in the rollforming overlap.
  • Check if the destacking process is going well. Make sure the tin plate is guided tight, and the separating air is positioned well.
  • Control the timing of the tin plate transport in between two transport fingers.
  • Make sure that the guidance channel is properly adjusted. The intersection to the precalibration of the calibration crown is most important.
  • Check the position of each (inside and outside!) transport finger compared to rollformed canbody.
  • Check the offset of each finger pair itself. Move the canbody slowly forward (X1 and X6 by slow mode function) and observe eventual shaking of the canbody until the welding point.
  • If a third finger exists: The third finger must be 0.5 mm behind the upper main pusher fingers!
  • Reset the calibration crown completely. Make sure that each precalibration roller is turning easily! If needed lubricate their shafts slightly and clean the roller afterwards. Make sure that these rollers are as close as possible to each other!
  • Measure the speed of the flat belt in the calibration crown:
    The speed must be absolutely identical with the copper wire speed!
  • Measure the overtravel: Short can heights shall have 1 mm overtravel.
  • The center of the diabolo roller (equal to the center of calibration crown) shall be 1–2 mm before the welding center.

This is the result of a wrong flexer setting!

Open the rollformer and you undo the screw on the right handside of the “Flexer”.  

Measure with a ruler the actual position of the flexing wedge.

On the other side of the flexer, you can alter the position of flexer with the M8 screw. Choose a lower position for less flexing.

NOTE:
With more flexing the sheet comes out of the flexer station with less prebending.

If you do less flexing, means that the sheet comes out of the flexer station with more prebending.

NOTE:
After adjusting the flexer, you might have to adjust the rounding slighty!
For more information regarding the flexer and rollformer setting check our manual book 2 chapter 5.4.

P03 = positioning countering error

Possible causes:

  • Resolver on the backside of the bodytransport motor is damaged.
    • Check if the bearings are worn out!
  • Resolver is not fixed well on the shaft.
    • Fix it!
  • Wire break in the cable between resolver and servo controller.
    • Check the cable!

The recipe helps to adapt the speed of the incoming can into welding roller and the actual welding speed. In the best case, those speeds are equal.

Below you find a table of this recipe in steps of 10 mm in can height.

 

Turn the wheel of the synchrostar, so that the pusher finger is as close to the welding roll as possible .

 

Now measure the distance from the top of the pusher finger to the center of the welding roll.

Distance = Can height – Overtravel

Example:
Can-height: 122 mm, Over-travel: 4.8 mm

Distance: 117.2 mm
