Someone that makes conveyors just called me to argue about a smema problem we had with his conveyor and our machine. He caught me off guard and I wasn't the person that handled the problem so I stumbled through this initial conversation. Now that I

I started writing a long winded explanation about SMEMA and realised that it is just as easy to write about this as it is to talk about it on the phone. It just so happens that I have recently gone through this process so I believe that your vendor

Here is how smema works: Machine A has a board to give to machine B. Machine A has an opto or a relay that will turn on or close when it is ready to pass this board to machine B. This is the "board available from previous" signal, telling machine B

Exactly. Poor Olas is pulling his hair out over an issue that has no business being "standardized". The SMEMA guys with apparently way too much time on their hands couldn't simply stop at the communications protocol and leave it at that....they had t

You should not be worried about these points in the SMEMA standard. You need to make it work for your application. If you are running really small boards, keep the gap between conveyors and the lead-in as tight as you can. If you are using large pane

I have a couple of questions about the SMEMA conveyor (standard 1.2); I posted the question to them but had no answer. SMEMA says: 5) Maximum gap. The maximum gap between the in-line machine track ends is 0.375� I would suppose this gap refers to th

Always happy to share information. Perhaps other viewers on this thread, can get some ideas of "how to". /Sincerely Ps. There is a so called "standard height" which the conveours/machines from different manufactories must be able to reach; without r

Conveyors are connected to machines with SMEMA cable interfaces; any edge conveyor manufacturer will have this interface.

SMEMA is not just conveyor height. It also is Conveyor width, Edge Clearance, Tooling pins, Maximun Machine gap, and Lead in of conveyor. Additional, SMEMA is a machine communications Protocol for machine to machine or machine to conveyor communicati
