This Glass/Plastic casepacker utilizes four separate
motion axis' to separate, control, and 'pack' bottles into cardboard
trays. Due to unreliable and foreign built motion modules and
controllers, it was desired to replace and upgrade the system
using Allen-Bradley components for maintenance and operational
Two motion axes provided separation of the desired # of 'rows'
per case. This was accomplished by a set of fingers on each servo
that help the backpressure off each set of bottles while the second
fingers kept the forward set together. The third axis controls
the set after it leaves the fingers and pulses at measured lengths
to allow sleeves to be inserted between the bottles. The forth
axis was used to drive a blank underneath each set of bottles
and into the gluing section for a 'wraparound' tray.
The existing Modicon program was modified to interact with the
A/B processor to provide specific parameters for each different
case setup and encoder feedback for the machine speed. The A/B
Controllogix program was written to interface with the motion
axes. A Prosoft MB+ card was used to provide the communications
between the two PLC platforms.
