How to make object on the conveyor snap to indexing rotary?

I tried to make an animation for bottle filling automation.
when the object smoothly can move on the spinning conveyor, it wont snap/stick to the indexing rotary which will be used as a grabber to place the object to each process (filling water, dropping bottle cap, screw down the bottle cap, and so on).

Maybe try disabling friction on the indexing rotary?

A litte forcefield in the gap to suck the bottle in maybe.
I guess the mesh collision shape is set to mesh!?

nope. still the same

i have no clue about forcefield to suck.
yes, it is set to mesh.

Are the blue transparent borders also collision objects? That may help

Here is a tutorial for forcefields:
