The disclosure relates to a turning device and a method for turning containers, wherein the containers are received between two turning conveying devices. The turning conveying devices are rotated about an axis of rotation in order to turn the containers. Furthermore, the disclosure relates to a transfer device and a method for transferring an article from a receiving container to a transferring container, wherein a receiving container is put over a transferring container at a put-over station in order to form a turning pair. The turning pair is turned by the turning device. Subsequently, the transferring container can be removed from the receiving container at a removal station in order to transfer the article to the receiving container.

In a roller conveyor system in which a product is being conveyed on rollers, a rotational arrestor may be used to dampen and/or stop rotation of rollers after a camera captures an image of the product where such image will be used to predict a location of the product at a subsequent time for picking or other manipulation. The rotational arrestor may comprise a shortened or limited-length traction bar that allows the rotational friction of the rollers to dampen and/or stop rotation of the rollers when the traction bar is not interacting with the rollers.
