The chain conveyor comprises a roller chain and a supporting rail adapted to vertically support the roller chain. The roller chain is provided with a plurality of roller members which are connected to each other by means of strap members. In order to laterally guide the roller chain with respect to the supporting rail, discrete guide elements are provided. These guide elements comprise a guide cam which protrudes the strap members of the upper run of the roller chain downwards towards the supporting rail. Moreover, the guide elements comprise supporting pin members which laterally project from the guide elements. The guide elements are located between the roller members and fixed to the strap members. The guide cam engages a longitudinal groove provided at the top of the supporting rail, while the lateral supporting pin members vertically support the lower run of the roller chain with the help of auxiliary rail members provided on the supporting rail.
L'invention concerne un transporteur à chaîne qui comporte une chaîne à rouleaux (6) et un rail porteur (5) pour soutenir verticalement ladite chaîne à rouleaux (6). Cette dernière (6) comporte une pluralité de rouleaux porteurs reliés les uns aux autres par l'intermédiaire d'attaches (1). Des éléments de guidage (2) séparés servent au guidage latéral de la chaîne à rouleaux (6). Ces éléments de guidage (2) sont pourvus d'une came de guidage (21) qui dépasse des attaches (1) du brin supérieur (6a) de la chaîne vers le bas en direction du rail de guidage (5). Les éléments de guidage (2) comportent en outre des ergots porteurs (22, 23) qui dépassent latéralement des attaches (1). Les éléments de guidage (2) sont placés entre les rouleaux porteurs sur les attaches (1). La came de guidage (21) s'engage dans une rainure de guidage (54) de la face supérieure du rail de guidage (5) et les ergots porteurs (22, 23) soutiennent le brin inférieur (6b) de la chaîne verticalement sur les rails auxiliaires (52, 53).
