conveyor cleaning system

[engineer983]

I am in the plastics industry and have a problem. The problem is we have a certain brand of injection machine that leaks hydraulic fluid from day one. Getting rid of the presses is not an option, I wish. No matter what we do we cannot prevent oil from getting onto the conveyor where the parts are dropped onto. A pick in place robot is not an option either. So, here is my question. Have any of you used a GOOD conveyor cleaning system. It would have to be 36" wide at least 12' long. All the vendors I have talked to so far say they have a cleaning system that will work good for a while, but will just begin to smear the oil all over the conveyor. Thanks a head of time for your input.

You write:
"No matter what we do we cannot prevent oil from getting onto the conveyor where the parts are dropped onto."
Why cannot you collect the leaks one by one or on a common tray and dispose of the oil before it reaches the conveyor?
Do you really think that a cleaning system employing solvents or emulsifiers in detergent liquids would not interfere with your production line?
Could you drop your plastic parts on a chute taking them away to bins or to a different separate conveyor that will not be contaminated?

Could you run the return through an open tank of solvent? There are several companies that make part cleaners with filters and skimmers for removing oil. There would be some solvent on the conveyor but it might not be as detrimental to your parts as the oil.

This does seem like a lot of trouble to go through over some hydraulic leaks. Can you change the design of the press or the leaking component? If there is not a major warranty issue I would go for changing the press design.

It's always best to solve the actual problem rather than add complications that allow the problem to be tolerated.

Fix the hydraulic leaks.

Or, if it is guaranteed going to leak, make it leak where you want it to leak, not where it wants to leak.

I am afraid that anyone who ever owned Stock Coal Feeders would tell you that hoping to fix the gearbox leaks vs. putting a catch pan; well, the catch pan wins every time. Some think it is a std part of the feeder.
