How to simulate workpiece carriers?

Creator
Creator

Hello community,

 

I want to add workpiece carriers (in german: werkstückträger) to my simulation.

Each workpiece carrier can hold one part. The Amount of carriers is limited and they will pass the simulation in a cycle (no carrier should leave the simulation).

What do you think is the best possibility to build this in plant simulation?

An second entity and a large amount of assembly and dismantle stations (for every station where the part is processed without the carrier?

 

Thank you very much.

you could use a little bit of SimTalk to avoid additional stations.
But, if the carrier keeps at the machine (empty) while the part is processing, you need not to separate the part from the carrier. You can keep them together until the drain, there you need to unload the carrier and send the carrier back to the source. There you can use an assembly station to load the carrier anew (e.g. to limit the parts inside the system). Keep it simple...

Hello Steffen,

 

thank you very much for your reply.

Your book helped me a lot to understand plant simulation and the examples are very useful.

 

You would use a second entity as a carrier and not a container?

Are there any advantages/ disadvantages?

I would use the container, but I would transfer the container (with part) into the machine.
The disadvantage is, that you loose some statistics of the part e.g. dwell-time. This you need to program via the container (e.g. calculate the time from loading to unloading).
