Placing items on a palette

Hi,

I am a beginner and this question might be a really simple one, but couldn't get an answer upon browsing the forums. I am trying to use ASRS vehicle to retrieve items(flowitem type1) from a rack and place it on the palette(flowitem type2) that is temporarily stalled on a conveyor. I got all the logic around it except for placing the item onto the palette. How to

1) define the number of items the palette can hold
2) achieve placement of items on the palette
3) Move ASRS tray to Unload the item at the point where pallette is present


Attached is the model. Please help.

thanks

Hi,

I think the easiest way to do this would be to use a combiner. It´s a standard object and most thinks are available on it´s GUI.

Only setting the place of items on the palet would be very difficult by using this solution.
If you really need it and standard functions of combiner doesn´t satisfy you, there is another way by using the command moveobject()
But this will mean you have to set position and size of Item by coding with using setloc() and setsize().

Flexsim Help shows very well, how to use all these commands;-)

Thanks very much Sebastian! I was able to use a label to define pallet size and the command moveobject to place items on palette. I am still looking to do task 3) which is having the tray move close to pallet present on conveyor while unloading to look realistic.

I believe the FRUNLOAD command has an argument that refers to the input port of object(in my example it is conveyor) to perform unloading. If I want to unload directly onto a item(in my ex it is pallet) present on the object, simply changing the destination to pallet is giving errors.If you run the model, it does indeed goes near the pallet for unloading but halts due to errors. Please advise.

Hi,
now I understand what you are talking about with point 3).
I but think this happens because your ASRS has to bring Items to conveyor. And this way to it´s standard entry position.
I see following 2 solutions:

1. Use a queue as destination of all items that leave rack. This Queue you can set at position for your pallet. Maybe you want to set position dynamicaly with setloc() again.

2. Try out to send ASRS to a destination and not to an object. For this you can use Tasktype: TASKTYPE_TRAVELTOLOC.
