Chesapeake Display & Packaging
CDP manufacturers advertising displays within their production
facilities throughout the country. Their displays in retail
markets typically accomodate items like batteries, candy products,
cosmetics, etc. They produce these graphic displays after
intense market research based on their customers needs and
specifications. They use a manual intensive workforce to assemble
and prepare these displays, receive and distribute product,
load the displays and prepare them for shipment. As with any
manual process, the time spent at each workstation dictates
the overall efficiency of the entire assembly line. CDP engineers
approached Piedmont Automation about controlling multiple
pacing conveyors to move components between the respective
workstations. By using pacing conveyors, workers have ample
time for assembly and the entire line is paced to be more
efficient. And because their customers all have different
needs, they also required that the pacing conveyor controls
be flexible, and mobile so they could configure the lines
for each product requirement.
Typically, material handling systems are fixed and centralized.
However, CDP has multiple facilities where their conveyors
are located and they needed to be configurable. Our team conceived
and implemented small individual control systems for each
conveyor providing adjustments for conveyor speed and dwell
time. Furthermore, we designed each system to act as a master,
or slave, which allows it to set the pace of the assembly
line, or follow the pace of another conveyor. The modularity
and dynamics of this control scheme gave CDP the flexibility
they needed to customize their material handling system on
an as needed basis.
Now they could group conveyors in any fashion necessary
to meet production needs, and what started out as a prototype
project turned into nearly 100 systems over an aggressive
- Simply control philosophy.
- Configurable & dynamic to meet production needs.
- Operator settings for speed and dwell time.
- Pre-wired cables and connectors for quick configuration
- Automation Direct PLC & other discrete controls for
- Designer PLC Software
Client Comments: "The design team at Piedmont Automation
really impressed me with their imagination and ingenuity.
Not only did they meet our difficult requirements, but they
were also very responsive to our aggressive delivery schedule."
