Picking speed

Posted in: , on 20. Jul. 2006 - 00:03

We are building a system of conveyors (15) total for the sorting of non-ferrous scrap. We are trying to standardize the conveyors and use the same gearbox and therefore same belt speed across the board. The capacity is not that high so slow belt speeds won't kill me. The problem is that some of the conveyors are stacking, some are feeding and some are picked off of by personel.

My question is, what is the optimum belt speed for manual picking off of a moving belt. What is the maximum recommended speed? What is the optimum belt height. The material being picked off is mostly small (less than 6" accross) and for the most part can be handled with one hand. The maximum reaching distance is about 30"

I appreciate any help anyone can give me.

Thanks,

Slow belt speeds might not kill the pickers either.

Even if the material can be handled with one hand its might be a good idea to fully enclose the belt edges & roller ends. That way if one hand gets tired there just might be another one available. Belts are lethal!!

Now examine the reach again. Thirty inches is not on.

Belt speed must be as slow as possible with 1 lump depth of burden. So if your lump is 6" then that will be your bed depth.

Use a flat belt. The Old Gits used to put little wing idlers at the end of longer centre rolls. But they didn't use the guards that you will have to supply these days & which will also keep the bits on the slow moving belt. Clearly safety pays dividends.
