why item on conveyor cant resume?

As said, I'm trying to make a model that when the flowitems arrive on DP, the conveyor below will rotate 180 degrees by its center so items on cv can change the direction. However when debuging the model, the flowitem can't resume on the conveyor. It seems like when finishing rotation, the items arrive on the DP again so it pull the event-trigge source again and continue the kinematics. Can u tell me how to fix it. Thanks.

Could you clarify what your goal is? Should the items rotate by 180° and continue moving in the same direction as before or should they stop at the decision point, rotate and move back in the direction they came from?

Generally I would recommend against rotating the conveyor itself. From looking at the process flow pictures you know how to change the movement direction of the conveyor (set the speed to a negative value). To rotate an item, use the respective pick option in a decision point/photo eye trigger.

To not have the trigger fire again after the conveyor has changed movement direction, you can use a condition that checks in which direction the item is currently moving.

Sorry I dont make it clear. Actually it can change the directions of item by 180 degrees by rotating the cv. In other words, item goes in the cv from one side, after rotating, the item goes out the cv through the same side as where it went in. Some items in factory require exact directions forward, so there are some equipments like thisto realize it. I made the item rotating itself by animation editor, but rotating the cv is more similar to real situation.

I understand, but then why do you also have the "reverse cv speed" activities? If you both rotate the conveyor and switch the movement direction, those two things would cancel each other out and the item would resume in the same overall direction as before.

If you prefer the visual of rotating the conveyor itself I would still recommend to not actually rotate the conveyor itself but rather place it inside another object (like a plane) and rotate that. Since the conveyor is normally defined by a start and end point and not by a single point plus rotation value, I fear rotating the conveyor might have unforeseen consequences.

The link below is an older post that shows how something like this can be done with a custom object, rather than trying to use a conveyor.
