Issue
I need to separate bundles with a stacker or push bar according to what the data says.
How do I do that?
Define the bundle end in your data
Here you see the standard bundle defined as 20, that means that the biggest bundle in the stacker is 20.
If the bundle from the data is 18 the controller will make one bundle of 18.
If the bundle from the data is 23 the controller will make one bundle of 12 and one of 11. This is because the minimum bundle is 5, that is, the stacker needs 5 to time before it pushes out the bundle.
If the bundle from the data is 26 the controller will make one bundle of 20 and one of 6.
Define your Stacker
A standard stacker is a stacker that takes a bundle exit signal (here output 3) and a stacker turn signal (here output 4). Below they are defined as a pulse.
A Harris stacker or a pusher normally expects that pulse just before the product falls into the stacker basket, thus, you need a shaft encoder that follows the product in the stacker.
A Sitma stacker expects the ZIP change on the machine, after the bagging, you can set it in the Sitma controller.
The Müller Martini stacker is a serial interface, not a signal interface but the serial command to push the bundle comes before the product falls into the stacker basket, thus, you need a shaft encoder that follows the product in the stacker.
