Plate advance problem

Anyone have any ideas about this problem....1st unit advances twice as much material as needed for every job. Im thinking it is a software problem?
Maybey reinstall footprint?

 

Hi Anthony, mostly the loses of plate material, are due to the pressman mistakes, when they are convinced they are saving some material.
If you don't make any tricks, and you are sure the error is related to the press itself. Just interchange Power board from unit number 1, with any other one and see if the error has moved. It is the only one board that could cause to long spooling.

Good idea! I should have known that. Nine out of ten times when the plate does not advance at all it is the power drive board.
I will give it a try and let you know.
cheers....

 

If that does not work try removing the roll, cut a new tab, measure it and put in the correct measurements. Sometimes the wrong info is input when installing a partial roll and the machine does not know how much to advance the material. The power driver board has no logic on it and only provides power. If there is a problem it would probably be related to the Logic Boards.

 

It's true Paul, but I've never have had any issue with the logic boards, and very often with the power boards.
It is firing the latch that unlock the full roll, and when this output is not switched off in time, it could spool more as it should. It could be mechanical problem as well in the electro valve that move this latch.

Removed the roll took a new measurment and reinstalled the roll.So far so good. It is is spooling the correct amount of material for each job. Im getting old and rusty, I should have tried this first. Im spending to much time behind a desk. Thanks Paul and Jan I appreciate your help.

 

Paul,
On the yellow unit only, a full roll will waste about 11-plates as it over advances sometimes. When we try to manually advance the plate and restart the plating process it will again do another advance while running before the imaging starts. all other units will work fine in both automatic and manual advance modes. any Ideas?

 

Jan,
Which part is the electrovalve? Our problem is the yellow unit overspills and it says there are 11 pate left but we ran out due to overspooling randomly.

 

Hi Ronrogers,
just try to put the fresh roll of plates, (could be the used one) and very important reset the counter. All problems with to long spooling are related to the mixed regimes at plates advance: once manualy and then automaticaly. You can run both of them but never one by one on th same roll.
When you chose to spool manually, you have to reset the counter after each spooling by hand.
Only the plate for the first job, after roll exchange remain unspooled on the cylinder, so you have to simulate exanging roll after every manual spooling.

<translated> Hello, We have a problem with our QUICKMASTER 46-4 PRO. We can no longer unwind reels of cyan group plates. It's totally blocked. Someone would have any idea ?

 

Hi sir
Good day
I recommend you to test the pneumatic clamping module :1) adjustment cloth brake 2) check hose connection.

 

The pneumatic plate clucth may be failing, as well as perhaps the plate motor tracking not work, in any case there are a number of steps to be able to verify that it happens. I recommend you to try to move the plate manually, you may see the plate very stressed.
