Chain conveyor changeable between a stretched configuration and a compact configuration

摘要

Conveyor for transporting articles such as a chain conveyor that can be changed between a stretched configuration and a compact configuration, the chain being formed from a plurality of articulated links. Each link includes a trolley provided with lateral guide mechanism cooperating with a track defining a predetermined trajectory, a support carrying a nozzle for the releasable attachment of an article, the support mounted rotatably with respect to the trolley between a straight position corresponding to the deployed configuration of the chain, and an oblique position, corresponding to the compact position of the chain and in which the support is inclined with respect to the straight position; and an actuator coupled to the support, capable of driving the support in rotation from its straight position to its oblique position, and reciprocally.

1. A chain conveyor for transporting articles with a chain that can be changed between a stretched configuration for transporting articles according to a first maximum spacing, and a compact configuration for transporting articles according to a second minimum spacing, the chain being formed from a plurality of articulated links the chain conveyor having an oblong closed loop with a rectilinear advance side parallel to a return side, the advance side defining a longitudinal rectilinear trajectory for the articles, wherein each link comprises:
a trolley provided with lateral guide rollers cooperating with a track defining a predetermined trajectory of the articles; a support defining an axis of orientation, said support being mounted rotatably with respect to the trolley around a principal axis between a straight position corresponding to the stretched configuration of the chain and in which the axis of orientation is collinear to the trajectory, and an oblique position, corresponding to the compact configuration of the chain and in which the axis of orientation is inclined with respect to the straight position and thus with respect to the trajectory, the support having at least one nozzle for the releasable attachment of an article; an actuator coupled to the support, suitable for driving said support in rotation from the straight position to the oblique position, and reciprocally.
