Spoilboard cover for unused sections?3/23
We have a 5x10 table Weeke Vantech with an auto push off. when we run 4x8 sheets, the operator puts laminate pieces over top of areas on the spoilboard that aren't being used, to increase vacuum. between putting these on, then stopping the push off cycle to take them back off, I'm guessing this adds at least a minute or two to our cycle time for every sheet.
What are others doing? I haven't tried just running the sheet with the rest of the spoilboard bare, but I do have 4 10hp pumps, maybe it would be fine? If not, what about some kind of masking film we can put down on the strips of spoilboard that aren't used for 4'x8' sheets that the pusher can go over?
Try contact paper.
Gary, I have the exact same machine, push off and 5 x 10. We run it all the time with nothing on the remainder of the table. If needed we put a 2 x 8 on the side and let the sweep push it off. Our machine is set to push about 2" in because we had an issue a while back where the push off grabbed the spoil board and made a bit of a problem.
Rebuild and configure your plenum so that you have one or more zones that cover that 48x96 area, and separate zones for the areas that are commonly unused.
Then you can open or close valves to shut off air flow from the un-used zones altogether.
Thanks to all for your responses. I'll try the contact paper and see how it goes. Reconstructing the plenum isn't an option on this machine, unless you want to carve out steel, aluminum and phenolic.
If that machine has a matrix table just grid off sections. We have multiple grids laid out on our CabMaxx table and the operator uses the vacuum lift to move the spoilboard and remove or replace plugs as required. You can make as many grid patterns as you need. This works much better than covering the top of the board, we tried that.
I have a 4x10 table, we run 4x8 and just gasket off the last 2'. We can run a 4x10 or 4x8 spoil board no problem. In your case run the full size board and u won't have any issue with the push off.
Clear packing tape works well. The cheapest kind can be plowed over with the fly cutter ... but Id try a piece first to make sure its not sticking to your cutter.
