High-throughput optimizing lumber edger with optical board scanning technology, electro servo sizing system, automated board alignment, 29HP or 40HP electric power, up to 460 ft/min variable feed speed, 19 - 11/16" max material width, and up to 1 - 3/4" max material thickness.
The Optimizing Edger uses optical scanning technology to achieve high precision and low waste edging of boards. The entire edging process is automated. First, each board is scanned. The profile of each board is then analyzed by a computer, which decides on the best product to maximize recovery. Decisions are based on both volume recovery and product value. After scanning, the boards pass through an alignment station and then are sawn. The EA3000 is capable of handling up to 25 boards per minute and is the ideal machine to edge boards coming from the Resaw. Electric servo sizing system achieves any width of cut without complication. Parallel PLC / computer control systems allow the machine to be switched over to manual mode with a single button. Online support allows our technicians to dial into your machine to troubleshoot it remotely. Overall, the Optimizing Edger is a simple, robust and automated solution to your edging needs.
Outfeed automatically separates waste from finished material.
Optimization
PC vision based optimization system calculates the best cut size for each board.
Hook-stops
The boards are carried on a cross transfer
with hook-stops. Dual limit switches facilitate
straightening of boards that arrive skewed. An
optional integrated flipper allows an operator
to flip boards in the wane up position. In addition, the hook stops on the cross transfer
effectively create a buffer so that several boards can be lined up and ready to be edged.
Board Alignment
With boards queued up, a set of speedup chains conveys the board onto the center
chain. Clamps and alignment arms center the board while top press rolls engage,
keeping the board firmly on the ramps when the centering arms release.
Two or Three Blades
The EA3000 features two or three (optional) independent blades which can be set asymetrically within the cutting window, thereby compensating for the exact position of the board relative to the cut zone. This feature greatly reduces the complexity of the infeed system while still achieving excellent sawing solutions.
With the edger set up to make precise cuts, the pneumatically-actuated feed chain engages the board and sends it through the sawing head. The board remains aligned as it travels through the optimized cutting unit resulting in cuts that are accurate relative to the board’s position.
On the outfeed, the wane is separated into a chute and a tailing chain conveys the board onward. Boards are then graded and stacked, ready for kiln drying or dispatch.
Scanning System
Using 6 cameras (1) and LED light bars (2), the EA3000 automatically identifies board dimension, shape, color, and grade; as well as unwanted visual defects.
The vision-based scanner easily locates bark and other characteristics which is not possible
with a geometric scanner. The simple to use industrial computer and windows-based software
identifies where the independently movable blades are placed to ensure the highest value
final product is produced. The net result is that recovery improves, product value improves
and down grade and re-work are reduced.
The EA3000 will edge dimensional lumber as well as random widths with the added
functionality of setting width priorities. Ready to achieve any cut without complication,
a signal is sent to the servo electric drives which move the blades to the intended position.
