ASRS: control the placement logic

[chanykE2WUT]

[ FlexSim 18.0.2 ]

Hi

I would like to get the ASRS extension to move to 0.5 m above the placement location in the cell of a rack before travel to the exact location in the cell for placement.

Is there any advise how can I achieve it?

Thanks

David

The best way to do it would be to use a travel-to-loc task. If you're using Process Flow, just use a Travel to Loc task with the x,y,z coordinates relative to the cell. And set the Z travel to go to the height you'd like.

If you're using the 3D model's logic to handle the task. Just use the custom task template and insert a travel-to-loc task prior to the Load/Unload task where it travels to the Z location height that you want.

Thanks for your advise. I have tried to use PF to do it. But it seems not working. Did I missed out something? I have attached the model for you to take a look. Thanks

So I apologize, but with the ASRS vehicle, it requires the Offset travel to be loaded. In the case of your model, this causes the Load task's automatic coordinates to go through instead of the custom one. So instead of using a load task we're going to use two extra activities instead. A Travel to Loc like I stated, but we'll also need to use a custom Place Offset task. (If you read the documentation on it, it explains how to use the Place offset task, but essentially it allows us to force the ASRS to move to the "unloading" coordinates that we designated with the Travel to Loc.) Then finally instead of using the "unload" task, we'll just use Move Item activity. Since the Travel to Loc, and the Place Offset already handled the travel and unload animation.

Here's an updated version of the model:

Thanks for your model. Can I move the extension say 0.3 above the placement then lower by 0.3 to place? It seems that I cannot use Travel to Loc to achieve this.
