To Cull or Not to Cull (at the Saw)
S
hould we cull lumber at the saw? That is the question posed by Joe Kannapell, P.E. in The Last Word in the July issue, “Where to Cull Lumber.” As Joe discusses: “So where in the process should we cull lumber? To minimize touches, it can be done when the bands are broken on a fresh Edmond Lim, P.Eng. LimTek Solutions Inc. bunk of lumber.” He goes on to say, “A better method may be for a linear saw operator to observe each board on the live deck. The operator has the best vantage point from which to cull lumber, and he can do it while boards are cycling into the saw’s infeed.” However, Joe surmises, “having the saw operator manage your culling may run contrary to the ‘right the first time’ principle...”. Whether it is a component saw or a linear saw, the sawyer always has the “last look” to re-crown or re-orient the lumber, and the sawyer also needs to check the work of the lumber picker to make sure the lumber size, length, grade, and piece count matches the order of the cutting list. If the sawyer has to cull any lumber, this will affect saw productivity by having to replace the culled lumber and will also result in ongoing extra effort to clear the saw area of culled lumber. The first picture shows an overview of the Enventek Lumber PickLine consisting of the SmartConveyor feeding the saw and the PickLine lumber trough loaded with full bunks of lumber to efficiently feed the SmartConveyor. The lumber on the front deck is ready for the sawyer to have the “last look.” Culled lumber stays out at the Lumber PickLine, which can be dealt with more productively away from the saw. (Note the dense lumber storage shed in the first picture used only to replenish the bunks on the PickLine lumber trough. Lean Manufacturing Tip: Avoid using dense lumber storage for picking lumber, with or without a PickLine.)
Enventek Lumber PickLine
An outdoor PickLine with dense storage is an easy upgrade decision backed up with an accelerated ROI as no roof is required and the PickLine itself sits on existing forklift paths.
