MONITORING SYSTEM FOR TRANSPORT CHAINS FOR CONVEYORS OF ARTICLES

摘要

Monitoring system for a conveyor of articles (100). The conveyor of articles comprises at least one transport chain (105) adapted to be moved along a movement direction, and a guide structure (132) of the transport chain comprising a lower guide element (135) adapted to support the chain from below and a higher guide element (140) adapted to insist on the chain from above and facing toward the lower guide element. The system comprises at least one first magnetic field generator element (155) located in a first guide element, at least one magnetic field sensor (160) located in a second selected guide element for sensing the magnitude of a measure magnetic field, and processing means (165) for quantifying a reduction of the overall thickness of the chain based on a time variation of the measure magnetic field.

1. A monitoring system for a conveyor of articles, said conveyor of articles including at least one transport chain adapted to be moved along a movement direction when the conveyor of articles is in operation, and a guide structure for the transport chain including a lower guide element adapted to support the chain from below and a higher guide element adapted to guide the chain from above and facing toward the lower guide element, said lower guide element and said higher guide element being static with respect to the movement of the transport chain along the movement direction, said monitoring system comprising:
at least one first magnetic field generator element generating a first magnetic field, said first magnetic field generator element being located in a first selected guide element selected from said higher guide element and said lower guide element; at least one magnetic field sensor located in a second selected guide element selected from said higher guide element and said lower guide element being different from the first selected guide element for sensing the magnitude of a measure magnetic field, said measure magnetic field ensuing at least in part from the first magnetic field, and a processing unit for quantifying a reduction of the overall thickness of the chain further to the operation of the conveyor based on a time variation of the measure magnetic field.
