SPI is a single
pass inspection system for the automated high-speed verification and
certification of labels for security sensitive industries, including
pharmaceuticals. |
 |
|
| |
|
SPI inspects, repairs, re-inspects,
slits and rewinds all in one pass. SPI is equipped with an active
web storage accumulator located on the exit side of the vision system.
When a fault is detected a signal is generated for the machine to
stop with a controlled deceleration. The machine then reverses and
the fault is placed on the editing table located before the vision
system. During this process the slitting and rewinding sections of
the machine remains frozen. There is no reversing of the web in this
zone. The material needed to reverse and place the fault is taken
from the active web accumulator. This feature ensures the integrity
and quality of slitting and the finished roll is uncompromised. |

Once the fault is edited
by the operator, the machine start mode is activated and processing
resumes. The fault is re-inspected by the vision system. The forward
motion of the unwind, inspection and accumulator sections start and
when the accumulator reaches a predetermined position, the slitting
and rewind sections start and the machine resumes full production
speed. View more details

DUAL PASS INSPECTION
(DPI) SECURITY, SLITTING AND REWINDING |
 |
|
|
|
|
In the dual pass mode, the
bi-directional inspection machine reverses the web to the operator
correction position when faults are detected. The web is then re-inspected
to ensure that the necessary corrections have been performed. |
|
|
| |
|
When the entire web has been
verified to be 100% correct, the machine enters a uni-directional
mode to perform the finishing functions of slitting and rewinding.
This non-stop second pass improves slitting accuracy and ensures rewind
roll tension consistency. View
