Box scanning capacity: max amount for box scanner/sorting (1 box/sec)

Hi,

Can I set a maximum amount on a DP (box sorting).

The actual scanner can only proces 360 items/hour, so it needs 1 second per box.

When there is more than 1 box per second the box should not be sorted.

Software Version:

FlexSim 24.1.0

@Roos_UTI, you need to be precise. You want to skip items in an interval of ten seconds or do you want to keep an ratio of 360 items passing in an hour?

You reset a label value in an interval of 10 seconds by message, looped process flow or repeating custom event. When an item passes this decision point it will set a different value at your label. This value indicating that any other passing item is diverted to a different destination. Elapsed interval will reset label value, which allows a passing of a single item again.

A constant rate of 360 items allowed to pass, depends on a knowledge of average capacity of items in an hour. Otherwise you will let pass first 360 items and divert the rest of incoming items until an hour elapses..

@Joerg Vogel mostly answered this in this comment. Though I think rather than resetting the ability to scan in a fixed interval, it should be based on the item since the last scan. Otherwise two items following each other closely could both the scanned when the reset cycle lines up correctly.

In the attached model, I set a label on the DP to the current time after an item is scanned (color changes and item is send to respective conveyor). Whenever an item arrives, the trigger code first checks this label and if the difference between it and the current model time is less than one second, ends the code execution before any of the other things happen by returning a 0 (Code Snippet).
