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.

Possible Cause (CM16 / S, X8):

  1. Check air supply for the cylinder.
  2. Eject cylinder must push the canbodies inthe center, the can must move verticallyaway from eject cylinder.
  3. Second light barrier is always ON.Sensor dirty or bad adjustment.
    LED on light barrier must be ON without can, OFF if a can is detected.
  4. Control wiring of first and second light barrier according electrical diagram.
  5. Make sure the faulty can is really ejected, means does not touch the edge of the bin and jumps back.
    => Use a fixed channel underneath the eject station, instead of a mobile bin!

Adjustment of the light barrier distance to eject cylinder might be wrong.

Wrong adjustment of the transport belt speed.

NOTE:
The ejected can should whether touch the can before nor the following.

Eject pulse cylinder has to fit to production speed:

Recommendation: 150-200msfor<100cpm 100-150msfor100-200cpm

80-100msfor200-400cpm

Place a canbody between the second light barrier and check the LED „LD3“ on the eject print (inside the Pacemaker).
Must be „ON“.

The autoreset needs to be “OFF”. Therefore the can memory will not be reset automatically.

Check, if your hardware parameters are set correctly, according to one of the three layouts.

Possible Cause (Pacemaker):

  1. Check air supply for the cylinder.
  2. Second light barrier is always ON.
    Sensor dirty or bad adjustment.
    LED on light barrier must be ON without can, OFF if a can is detected.
  3. Adjustment of the light barrier distance to eject cylinder might be wrong.

  4. Wrong adjustment of the transport belt speed.

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!
