Belt Receive
Description
This project was done for Quad/Tech. In general, magazine finishing machines
use lugged conveyor belts to move magazines down the line. The lugs provide
a very precise method of tracking the location of each magazine and where used
to trigger events such as caliper checks. Some processes, however required
that a belt be used to move the books. These where used for folded mailers.
Up until this time, the two methods had been used seperatly. Either a machine
was lug driven (custodial) or belt driven (non custodial). On a belt driven
machine, cameras were required to trigger events. The goal of this project was
to allow a custodial section to run into a non custodial section.
Challenges
This was an extremely challenging problem. The entire infrastructure was build
with the two different machine times in mind. There were no allowances for
using a different type of tracking on either. Custodial systems required an
encoder to signal interrupt that woke up process along the line while non
custodial section used camera to trigger events but otherwise had not tracking.
A number of people where required to make the modifications neccesary to get
this project working.
Results
This was a successful project and was used in plants in Virginia to perform
print on folded mailers.
