I created a mechanism for moving objects from the chest to the funnel, and then to the trolley, then from the trolley to the lower funnel and to the chest. It didn’t work, the objects got stuck in the funnel. It turned out when the blocks (on the side) next to the funnel did NOT ACCEPT objects, I myself can’t build a mechanism. To clarify the situation, let's say a funnel at coordinates 3 -1 3, and a block at coordinates 4 -1 3. And while the block exists at these coordinates, the funnel DOES NOT ACCEPT or SEND resources.
