Continuous pick in conveyor fails with processors

Hi, Everyone. Please check the model I attached.

I want to continuous pick the item from multi-exitTransfer in conveyor. It works well if downstream objects are queues. But fails with processors. After taking one item the operator can only pick item in the last exitTransfer.

Could anyone give me an advice?

Any suggestion will be appreciated!

It looks like not the destination object type but the long distance of the operator's walking.

The fail of picking up in the wide range transfer is the operator's taking time to the exit zone.

Thanks for your reply.

You can see the first 3 operator do pick one item from the conveyor at first. But when it start accumulate at the end of conveyor, only the last operator keep working. I think it's more than the distance question.

The pic shows that even such close, the fist operator would not pick the item.

It works well if the downstream objects are queues which is what I really feel confused.

Could you set the capacity of the processors high, e.g. 100. Then test your model again. The standard capacity is 1 for the processor. The capacity of queue is 1000. As long as 1 item belongs to the processor none taskexecuter can transport items to this processor at all, if the standard capacity is set.

Thanks @Jörg Vogel.

I had tried to set the capacity big enough for solving this question. And It works well.

But I still wonder why the capacity is 1 would make it work weird. I try to set Inter-arrvialtime bigger(like exponential(0.0, 30, 0)) to ensure only one item can show in the conveyor, And only the last operator was moving items.
