How to inspect a large corrugated sheet offline
Offline inspection of a large corrugated sheet has to be able to say which sheet in this stack it was, not only flash on a screen. The sheet is wide, so cover the barcode, the product name, and a whole missing color first.
Offline inspection of a large corrugated sheet has to be able to say which sheet in this stack it was, not only flash on a screen. The sheet is wide, so cover the barcode, the product name, and a whole missing color first. Loosen the flute to the signed sample. An offline look needs a stack number.
Why it is judged this way
If a board is put on the inspection table with no sheet number, a later complaint cannot be traced back. A number can be inkjetted or scanned as the sheet comes onto the table. However fast the inspection is, if the original sheet cannot be found, the offline station was only a glance.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| There is a sheet number or a stack number | It can be traced | Keep only a shift pass |
| The barcode is damaged or a whole color is missing | Take that sheet out | Pass it because offline is too slow |
| The flute false-alarms | Loosen the texture to the signed sample | Switch the whole machine off |
At job change or when a roll is opened
- Before the sheets go on, set how this stack is numbered.
- Pull one missing print and confirm the alarm.
- The pass record has to include the number.
