The Saw Control unit is the catalyst in
identifying areas of non-production and
non-recovery. It will act as a
non-partisan "fair-play-referee" in
identifying problem areas, both
personnel and machine related. It helps
key disciplines eliminate hours of
non-productive labor spent trying to pin
point sawing problems. The System is
designed to be user friendly, allowing
all users easy access to information and
encouraging interaction between each
department. |
Benefits for Mill Management |
| |
 |
Aids in Safety by
alerting of machine or saw problem
|
|
|
Gives overall "picture"
of how the mill is cutting
|
|
|
Allows for production
to be based on Quality and Quantity
|
|
|
Aids in reducing
fall-down grade
|
|
|
Allows mill maintenance
to be scheduled
|
|
|
Assists in reducing
unscheduled saw changes
|
|
|
Assists in reducing
target sizes and perhaps kerf size
|
|
|
Aids in increasing saw
blade life
|
|
|
Aids in rating job
performance of mill personnel
|
|
|
Benefits for Safety |
| |
|
|
Allows for safer work environment in
and around the bandmill |
|
|
Warns of excessive mill and saw
vibration |
|
|
Warns when saw has lost tension |
|
|
Warns when saw has extreme cracks |
|
|
Warns of bearing failure |
|
|
| |
"Display of BAD bearings on
scope" |
|
The Mill Safety
lights feature from Saw Control consists of a visual display on the
mill floor. In a nut shell the Saw Control will have an alarm set
point established for allowable vibration, and anytime the vibration
duration limit is exceeded the output circuit will be activated.
|
|
|
Benefits for Filers and Maintenance |
| |
|
|
Alerts guide buildup and /or guide
wear problems |
|
|
Aids in determining saws for correct
tension, tire and tooth shape |
|
|
Alerts of bad saws or guides without
culling wood |
|
|
Warns of bearing problems |
|
|
Shows saw cracks |
|
|
Shows dull/sharp saws |
|
|
Assists in training of new filing
personnel |
|
|
Aids in targeting maintenance of
band-mill and carriage |
|
|
Assists in evaluating saw filing
equipment |
|
|
Gives overall "picture" of alignment
in real-time |
|
|
Assists in sorting out machine
alignment and saw-tooth problems |
|
|
Aids in getting mill maintenance and
filers working together |
|
|
|
Benefits for Production Personnel |
| |
|
|
Allows
operators to "push" to the maximum feed allowed (within parameters
set by the mill) |
|
|
Aids in
reducing "miss-cuts" |
|
|
Gives
"picture'' of problems that occur |
|
|
Logs
Every cut made |
|
|
Allows
for schedule saw changes and/or guide replacement |
The greatest benefit seems to be the filing personnel calling for saw
changes on their own. Also the ability to know if the "snaking" is due
to a weak saw or trash buildup on the guide. These events result in
steady production and balance work loads in the filing room.
|
|
|
Benefits for Quality Control |
| |
|
|
Alerts operator and /or
displays lights when miss-cuts are occurring
|
|
|
Deviation determined by
parameters set / tolerance allowed
|
|
|
Monitors EVERY cut made
|
Aids in determining where problems occur - saws or feed-works
With the light display visible on the mill floor QC will be alerted
when sawing begins to exceed acceptable sizing. This allows QC to
focus on size and grade issues from multiple machine centers with
confidence that out of spect lumber will not be found down line in the
process.
|
|
|
Benefits for Machine Operators and
Sawyers |
| |
|
|
Alerts when problem
log being cut
|
|
|
Allows maximum feed
speed on good saws
|
|
|
Warns of poor
performing saw
|
|
|
Aids in determining if
/ when saw change is necessary
|
|
|
Warns when there is
guide buildup and/or wear
|
|
|
Assists in training of
new operators
|
