Abstract

La présente invention concerne un mécanisme de restriction de transport pour restreindre des produits à transporter. Le mécanisme de restriction de transport comprend un élément de restriction de transport qui permet le passage de produits ayant une hauteur égale ou inférieure à une hauteur prédéfinie, tout en attrapant les produits ayant une hauteur dépassant la hauteur prédéfinie et en restreignant leur mouvement en aval par rapport à la direction de transport. Le mécanisme de restriction de transport prend en charge de manière sollicitée, avec une force de sollicitation prédéfinie, l'élément de restriction de transport à une position de restriction correspondant à la hauteur prédéfinie et supporte l'élément de restriction de transport de sorte que l'élément de restriction de transport puisse être déplacé vers le haut et vers l'aval par rapport à la direction de transport par une force externe qui dépasse la force de sollicitation et est orientée en aval par rapport à la direction de transport et puisse revenir à la position de restriction lorsque la force externe cesse.
