ASRSvecycle send port error!

Hi.

When I play the file, it stops once in the middle, even though there is room for entry. If you look closely at the movement, you can see that it is waiting to put the item in a full port, not an empty port.

1. I want to send it straight to the empty port, is there a good way?
I've been forced to create a PE block and blocked the port, but it doesn't work.

2. And, if you look at ASRSvecycle1, there seems to be buffering for about 7 seconds before loading. I didn't give loading time to ASRSvecycle1, so why is this?

3. Finally, when I see the ASRSvevehicle1 device when unloading an item, it returns to the home as soon as it unloads the item. I also need the condition of returning to the home, but I want to implement the appearance of returning to the home after a certain time has passed since unloading an item, or after a certain distance has passed.

I'm not sure what it means.


I made modeling in a free version, so I don't have a license.

In your picture I can’t count at any exit transfer a number of output ports larger than three. In your code you divert items in default case to port numbers in a range of 4 to 6. If this default case gets executed than the involved item will not released. And this can cause that your will get into a stop.

I know. The above model has some of the whole off. And since the station on the line connected to the source sets the label to 1, it's not a problem.


The current problem is that, despite the fact that there is a situation where one item can fit in the sink line, there is a momentary stop because ASRS is trying to move the item to the side where the line is full.


If you look at the code now, you can see that when the label is 1, it is duniform(1,2). As far as I know, the probability is 50-50, I would like to change this code to first available code among 1 and 2.

@kimsh, please give us the whole situation you want to accomplish:
  • how many types are available to be diverted?
  • which ports they go to?
  • is it a ratio, a statistical distribution or a port by other condition you send them to?

please be precise, what you want an answer for.

Try it with input pull option in entry transfers of your conveyors:

Pull Requirement an Array or Range of Values allowed to enter.
