Hello!

I’m brainstorming how to replace the outfeed table on my rip saw with a catch bin.

I’m installing a power feeder on my table saw to make milling large quantities of stock much easier. I’m ripping 16’ boards @ 2” and 1.5”. I’m excited to have the feeder setup to make ripping a few hundred board feet of material easier and SAFER!

Question is: has anyone ever seen a setup where the work piece coming off the table falls into a bin so you can keep ripping without stopping to move the work piece out of the way? I’m imagining a scenario where the leading edge of the 2nd work piece pushes the first one off the end of the table into the bin. The problem is, the 16’ rip is so long that the far end would fall as soon as it clears the feeder such that the 2nd piece would not cleanly push the first out of the way.

Anyone have any ideas on how I could build a bin that would guide my workpiece off the tool and into a pile?

Thanks!

Automating wood handling is relatively easy. Just need lots of volume to justify cost of all conveyors and equipment. This commercial equipment site might give you some ideas:
https://www.tsman.com/saw/tsmfg-saw.htm

My suggestion:
If your ripped width is always similar size, and only couple inches wide; build a narrow flat out feed with sloped table attached to one side. Once board is finished, push closest end to saw (with push block through a side fence) down the slope. When the next board feeds out, it pushes the previous one down the slope rest of way. Commercial line would use 90 degree conveyor to drive each board sideways onto the chute. Make slope panel 8-16” long terminating into catch bin. Wouldn’t make the catch bin more than 12-16” deep to avoid damage during slide/drop. Use removable sides (or U shaped guides) with internal raised supports and you can use shrink wrap or banding to tie up the bundle, before removal.

This is basically how a production out feed conveyor/stacker works. They are commonly used on 4 head molder when producing T&G flooring (they stop the fall to interlock several boards on ramp, then drop entire panel. On production straight line saw, or painting lines; the output bin is replaced with a conveyor to move boards into separate grading and stacking machine. Tons of options if you can justify the costs.

Best Luck.
