Stamp handling
July 1st 2007 Stephen Mayer
International's PAC-24 has
been designed and
developed specifically for
the United States Postal
Service (USPS) in Kansas
city, using Festo
components throughout.
The machine
automatically peels the
stamps from their backing
sheets and affixes them to
the target material
individually, in a line, or in a
grid, depending on the
customer's requirements.
In all, the PAC-24 is
equipped with 10 Festo
electrical servo drives, which
are mainly used for the X-Y
tables, the backing sheet
removal coordination
system, and positioning the
tamping cylinder. All of these
drives, together with the
system's four CPX valve
terminals, are under Profibus
coordination and control. To
maximise machine
throughput there are two
mirror-imaged stamp feeder
stations on the PAC-24,
arranged either side of the
central indexing envelope
feeder conveyor. Finished
envelopes are transferred via
a camera checking station
to a collating conveyor More articles from Festo Limited: |
