Modeling a double screw buffer

Solution Partner Legend Solution Partner Legend

Hello,

 

This is probably a simple question, but how would one most accurately model a double screw, i.e. "serpentine" buffer as pictured in the attachment?

 

Is it possible to model with only one buffer object, or would a combination of buffer objects be needed? As expected, when the first MU enters the buffer (in real life) it takes some time before it reaches the end. But as the buffer fills over time, the time it takes for each MU to exit increases. Is this situation best solved with a Dwell Time and buffer type Queue?

 

Thank you.

If a abstract representation is sufficient you can use the buffer. For a more realistic (also optical e.g. 3D) representation you can use a accumulating line.

But wouldn't the buffer need a dwell time? If I only insert a buffer, the MU moves directly from the buffer to the succeeding station instead of simulating its travel along the buffer (taking time to exit).

Thank you also for the advice regarding 3D representation Smiley Happy

in tab times you can set a dwell time for each part in the buffer. The parts are available after this dwell time. Set the eventcontroller to realtime to see the effect.
