Log deck and green chain

@Red Beard  I saw that set up but since I work alone I don't think it would work very effectively for me. I need a place for slabs to accumulate. I'm hoping to only have to move to the edger once or twice a day. The spiral rules seem to have more hangups also than a sweep or popup table.

The following video shows a linebar working. I'd expect  a wiper bar to be set up like that except that the rams would get set up lower under the rollcase. By setting them low you can go either straight ahead down the rollcase, push (in that video) left.... but you can also set the bar left and pull material back to the right hand side over where those rams are placed. And air rams rather than hydraulic - they need to move fast.

What I love is the simplicity compared to tilt tables, and I suspect it will outlive them a while too because there's not much there to wear out... couple cylinders and some bearings or teflon blocks.

[PAmizerman]

That just might be doable say_what
It would take less steel and air cylinders.
It would also shove everything straight off without it getting catywompus.

@Percy could you take some close up pics of your kickers for us? What did you use in the way air cylinders and how are they attached?

Sure.  I'll do that tomorrow.(pics)
 My stuff is pretty crude but it works well.  The air cylinders are 80mm x 500 mm. There are two for each wiper. Rough math tells me they push near 1000 lbs at 120 Psi. The motion of my wiper is an arc as the whole abortion pivots on two vertical shafts about 8 feet apart. Pics coming....?

OK Here is a short video I made today....Im not the best speaker/splainer so...

Show Me for PAmizerman - YouTube



 
THe business end of the air cylinder




 
Different shot of the same thing



 
This is the arm that goes to the wiper itself...



 
The anchor end of the cylinder.....made outta old fine adjust outriggers offa the LT70
The rod you see going over the cylinder is a link(tie rod) from both wiper pivots. If I had built this completely out of metal, it probably wouldnt be needed.




 
THis is a Jake switch off an old log truck. It has three connections, ground, normaly open and normaly closed...With a little pondering, and some household light switches and a battery, you can power the 12 controlled  volt air switches so the wiper can be a two way thing...

Ask me any questions about this and Ill do my best....

Percy - on the mud flap how did you set it so flitches would pass by even though they push the flap?  Would 2"  - or whatever size the flap is set for - always trip the flap and under that will pass by?

I wired it all to a control panel at my remote station. I can switych on for left, or right or strait thru.....if I remember...heh...There was a learning curve.....I have it set very sensitive as my ajustable activator is a piece of licence plate... :D

[Southside]

Ahhh - That makes sense, must be quite the pile of wires running back and forth!!  

[PAmizerman]

Thanks Percy that video really helped me understand a lot better. Thanks for taking the time to do it!!

[YellowHammer]

Thanks for posting the videos and the explanation.

Actually, its not as many as you think. I have two separate wipers, the two way one I showed in the vid and another  farther down the roll case that only goes one way. The whole system is done with a 7 wire log trailer chord. And three householed light switches with enclosure(Ill take a pic today). One of the light switches is the one with the extra terminal. You could use a simpler switch at the mudflap and a bosch type 5 pin relay and get the same results. I was worried that after 60 feet from the battery, the electric over air switches might not function properly....but they work fine.

No problem. I have more fun building this stuff than milling....Sometimes I build stuff that dont need building ;D...but this system is a time saver for me. I cut alot of bridge timbers (8x10x16, 3x10x16,10x10 etc). I can load up the log deck, and cut maybe 2000 bdft of afforementioned stuff before I have to leave the operator station, cept for rolling logs into loader. Cutting smaller works well too. 8 footers are my least favorite and 10s can be a pain too.I need to modify my output conveyor with a roller of sorts to assist with this. The super LT70 and WM4500 have way more return speed than my old coffin dodger 2003 LT70 which gives the dragged back piece more inertia avoiding this minor hangup....

@Percy  so where the swing arm bolts up through the wiper, that is the only attachment point? Do you have a piece of plate steel welded to the arm then attached to the wooden wiper? 
What keeps the wiper from pivoting on the bolt that runs up through it?

There is pretty much an identical scenario to the one shown here but at the opposite end of the wiper..  If the distance between the center of each pivot is 8 feet(cant remember exactly), then the holes in your wiper where it sets on the end of the swingarm should be the same. If you notice in the pics, the piece that the business end of the air cylinder hooks up to goes past the center of the pivot. What you dont see is a 3/4 inch metal rod that goes to the other identical setup. So I have the wiper as a link between both setups and this metal rod. My wiper just sits on a 3/4 inch bolt welded to the end of the swingarm. A washer is welded at the appropriate height to keep the wiper from rubbing on the rollers etc. The distances from from center of pivot to center of wiper bolt is important as is the distances for the extra rod I have. The reason I added the extra rod was to keep everything in line when most of the wiper push is at one end for whatever reason..If you build out of steel and use bushings at all pivots and accurate measurments, and built nice and beefy, you would not need that extra rod I speak of.... I hope I answered your question... :D

[PAmizerman]

I believe I understand. So there are two cylinders on each wiper? That makes more sense.

[PAmizerman]

I reread that again. So only one cylinder per wiper but hooked to another pivot point to keep everything swinging semi parallel to the roll case?

[Percy]

Two cylinders per wiper. Ima lousy splainer bear with me 😳

[Percy]

You seem pretty articulate. Let me know what you need to see and I'll take pics of it

[PAmizerman]

I'm not very good at visualizing. I do good with pics and hands on. I think I got it now! It's also been a long day :D. My brain shut down for the day! Thanks Percy

[Percy]

My drawing skills approach my ability to explain properly....Maybe it will help...this is top view

[YellowHammer]

Thanks

[PAmizerman]

Yep that helps 
Thanks

[PAmizerman]

@Percy do you need both cylinders to function properly?
 Or do you have two just to move the really heavy stuff?

[Peter Drouin]

Nice set up Percy.
