California Redwood Company. (ex Simpson Timber Company)
Korbel, California
Project:
From concept to commissioning, this 14-month redwood and fir planer mill project started with the removal of all the existing mechanical equipment. Pacificon was responsible for the design, documentation, programming, fabrication, supply and on-site commissioning of all control system equipment including PLC panels, operator consoles and junction boxes.
Details:
A partial list of equipment and documentation supplied.
3 Controllogix PLC’s were used in the Planer Infeed Area, Trim-Sort Line and
Package Handling areas
2 additional ControlLogix PLC’s were used for specialized motion control for
servo drives and hydraulic linear positioners
2950 I/O points in nine 17-slot racks & 18 Flex I/O drops on Ethernet I/O network
interfaced to consoles, panels, MCC’s
34 VFD's were controlled by an embedded Ethernet interface module in each VFD
150 standard drives were each controlled by a DeviceNet E3 Plus module
10 MCC's interfaced to PLC via 10 EtherNet to DeviceNet (EN2DN) converters
7 Panelview 400 Plus HMI’s with Ethernet interface for local status and alarm messages
An RSView32 operator interface was used for sorter setup and troubleshooting
Controllogix PLC communicated to the CNM Linear Optimizer via ControlNet interface
600+ AutoCAD drawings
Notes:
A new "Skip-a-Lug" feature was added to provide an empty lug for Cut-in-Two Board Trim Solutions.
Several high-performance servo motors on a SERCOS network were used to control the
“soft coupled” TRIM-SORT lugged transfers. The 3 Grader Stations were also controlled with "Soft-Coupled" servo drives.
A fully automated Tray unloading feature was provided to automatically sequence loads into position for the high-speed lumber stacker.
The high-speed lumber stacker was controlled by a linear positioner for the hoist and a servo motor for the forks. The servo motor controlled forks was a new design from CNM that we successfully commissioned on-site.
The client had an existing Inventory Tracking and Shift Reporting system they wanted to retain. We provided all the nessesary communication for this in-house system.
