What I get paid for:

[Keith Wilson]

This just showed up; thought it might be of some interest. The video shows the 'sandwich maker', a custom door assembly machine I designed a while ago, maybe six or eight years, for the Oshkosh Door Company. There's a roll-coater upstream that puts glue on the top surface of the door skins, and downstream it runs thought a ten-roller pneumatic press to stick it all together. Fairly straightforward, really, about one door a minute; the cute part is that it handles a wide range of sizes with not much changeover. It really should have had an automated stacker at the output end, but they didn't want to spend the money. They're selling the line, apparently, and this is a video from the machinery broker, so it might disappear once it's sold.

Good stuff.
I work with some automation products, but in applications which barely scratch the surface of what the tech can really do. Every so often I come upon a system that goes deep beneath that surface and I'm blown away.

Slow.

[CWSmith]

That's very cool and surprisingly calm. Thank you for sharing that.

[L.W. Baxter]

clever. and nice and quiet for an industrial process. like making copies. [insert snl clip]

[L.W. Baxter]

Slow.

probably just exactly as fast as it needs to be. there are things happening before and after. no sense speeding one automated process that outpaces any others.

[TomF]

very cool. Thx Keith!

[Jim Mahan]

Nice.

[CWSmith]

Slow.

I'll bet that faster would dent the edges of the skins and produce sloppy placements that result in a poorer product. A faster conveyor would probably require a longer oven to heat the glue which adds cost. I'll bet the speed is right for the process.

[Keith Wilson]

Slow.

I prefer 'stately'. The speed is determined by the roll coater applying the glue upstream. And faster costs more.

Well... you gonna show the the edge banding? The hole cutting? The finishing?
Or you gonna leave us hanging?



Thanks for sharing.

I didn't have anything to do with that, and that's the only video I know about. Edge-banding is pretty standard equipment; this was a complete one-off. I didn't even see the finishing section, in fact; that was at the other end of the factory

Very impressive but I didn't realize slab doors were a thing any more.

[bluedog225]

Very cool

[David G]

Nifty materials-handling gizmo.

I assume it's not precise enough that the skins are applied net/net... but require later trimming. That seems like it would be a huge ask.

Am I seeing that right... the company is building solid-core doors with OSB edging? That would be hugely lame.

Thanks for sharing. Production engineering is always interesting for me.


WAIT!!! Are you telling us you don't get paid just for showing up with your inspirational good looks and charming personality?

[sandtown]

Brag much ??

Humor alert - just kidding.

Thanks for the interesting post !!

I use an expired credit card to spread Titebond II. Kind of messy and it always feels hurried. Once I cut notches in the edge of the card. Not worth it that I saw.
