サーボ3000を使うと、印刷機内の紙パス分で見当が合います。 –
実際にどの機械に搭載しても最少の基材長で見当合せが終了します。
Many presses starting up will have color “pull out” as the press ramps to
speed, then slowly regains registration.
This happens each time a roll is
changed, waste matrix removed, material splice comes through, etc. Any material
used beyond press length is unnecessary.
The Servo 3000 also helps in areas harder to
quantify such as reduction in make-ready time and material, and the ability to
run the roll down to the core. Plus you get every benefit of having a
re-register system.
Information needed:
You will be entering your own
company data into the calculator and much of the information you already know.
Some of the data will require press observation – i.e. how many times does my
press start/stop in one day? Finally you will need to know two key pieces of
information as follows:
How much material is in the press from the first print
unit?
To determine this with the press stopped, flag the roll at the
production rewind and mark the web with a marker at the first print unit. Run
the press until the mark is at the rewind. Remove the material by hand between
the mark and the flag. Measure the material using a tape measure.
How much material is wasted to get the press into register
after a restart?
To determine this with the press stopped, flag the
roll at the product rewind. Run the press until it is back in register and
flag the product rewind a second time. Remove the material between the flags by
hand and measure with a tape measure.
Definitions and
Formulas
Described below is how we calculated your information and the
formulas we have used.
Daily Savings
Daily footage saved = Feet wasted to get press in
register - material feet in press
x stops per day x per shifts per
day
Cost of daily footage saved = cost per MSI
x daily saved MSI
Daily save MSI = Daily footage saved x web
width ÷ 1000
Time/Minutes Saved = Daily footage saved
÷ Average press speed
Overhead cost Saved = Press overhead ÷ 60 x
Minutes saved
Summary Overview: Projections are based on a 20 day work month, 40 hours work
shift. All time calculations are converted to hours. |
