Problem about Separator

Hi,All
There is a problem about Separator when I'm simulation. The flow is described as:
1. use combiner to pack two BasicBoxes on one pallet;
2. send the loaded pallet to a separator through a conveyor;
3. the separator unpack one of the BasicBoxes, then send it to port1, the remainder (a pallet with only one BasicBox) is sent to port2.
The problem is it always unpack the both two BasicBoxes and keep nothing on the pallet.
I tried many ways but failed. Is there any one help me? Thank you.

It sounds like you're using the default "Split or Unpack Quantity" option to unpack the "Entire Contents". Use the option "By expression" and define the unpack quantity to be 1.

Thank you.
Maybe my description is not very clear. In step 1, I pack the two BasicBoxes together, then pack them with the pallet, after the two operations, I use a separator to unpack one of the Basicbox.
And I am sure, I chose the method 'Unpack Quantity of 1', but failed. It always unpack the two boxes.

Wutian,

Could you please post your model, then one of us can take a look to see what is going on.

OK, I just attach my model. I'm using version 3.5. Please help me checking it. Thank you.

Wutian,

May I first propose you update to the latest version (4.32) because you don't have to compile anymore (with new models that is)

I checked your model but why do you use the first combiner (combiner3) because that one puts 1 box in the other and on the second combiner where you put the boxes on the pallet you only let 1 box come in. So on the conveyor after the combiner, your pallet looks like the attached bitmap.

So as you can see there is only 1 box in the pallet so only 1 can come out and then the pallet is empty. If you remove the first combiner and let the source simply generate 2 products and on the main combiner say that you want to receive 2 from the input port 2, your model should work.

Steven

Steven, thank you for your reply.
Yes, as you say, the model does work. But packing the two Boxes is necessary. Maybe I have to change my way.

A Separator's functionality is easy to duplicate with code. You could just use a regular Processor, then put the following statement in the OnProcessFinish trigger to move out the inner-most box:

moveobject(first(first(item)), outobject(current, 2), 1);

The only thing you need to be aware of is that the moveobject() command doesn't wait for availability, but simply moves the flowitem immediately.

Hi, Cliff. I can split the box as you told me. Thank you.
