Hi
Have an application where there is one product conveyor and 1 box conveyor (where the products are placed).I have one contanier where I have defined the pattern in the box.
The box is tracked(200mm) to the stop position and most of the products are placed at the stop position.
If I let the box go to the stop position without the robot placing any products in it the box stops at the correct position (defined as stop in the conveyour area) but if the robot do place products before the box has reached the stop position the box goes some 50-100mm longer than defined in stop!!!
But isn’t the value you define in Start/Stop always a fixed distance to the baseframe?? and if that’s the case I still doesn’t understand why the conveyor stops at different positions.
The process is always supervising the current first unused item in the queue.
If the Stop limit is set to 100 and the Start limit is -100, the conveyor will stop when the current first item in the queue passes 100 mm beyond the center of the robot and restart again when the first current item in the queue is more then 100 mm from the center of the robot.
What happens in you case is that you place the first one on the fly, the supervision will switch over to be made on the second item in the container, which have now become the first unused item in the queue.
Ok I understand the behaviour now.
Just one more question, what is stopping the conveyour in my case? The box has paste the stop point and there are no other boxes on the conveyor.
