Abstract

A conveyor apparatus for advancing articles in a direction of conveyance, including a conveyor track on which the articles are supported; an endless driven conveyor element and an article carrier device including an article carrier element pivotally supported on the endless driven conveyor element. The article carrier element is adapted to engage and thus convey, or be disengaged from an article on the conveyor track. The article carrier element comprises a pivotal lever and a carrier lug formed on the pivotal lever. The latter has an activated pivotal position in which the carrier lug is adapted to be brought into and maintained in a force-transmitting engagement with one of the articles and a deactivated pivotal position in which the carrier lug is maintained disengaged from the articles. A force-exerting device urges the pivotal lever into the activated position. There is further provided a contact element on the pivotal lever downstream of the carrier lug as viewed in the direction of conveyance. The contact element is arranged for being depressed by a downstream situated object for causing a rotation of the pivotal lever into the deactivated position.
