CONVEYOR WITH INDEPENDENT CONTROL OF MULTIPLE PALLETS

摘要

Apparatus for detecting the position of a moving element relative to a stationary element, said apparatus comprising: a plurality of linear encoder readers spaced generally along the stationary element at fixed positions relative thereto; a device readable by the linear encoder readers, the readable device being mounted on the moving element and having a length which is greater than the spacing between any given pair of adjacent linear encoder readers; guide means for aligning the readable device in order to interact with the linear encoder readers; and processing means, connected to each linear encoder reader, for associating the readable device with only one linear encoder reader in a state of interaction with the readable device at any time and for resolving and providing a reading of the overall positio n of the moving element based on the fixed position of the associated linear encoder reader and a relative position of the readable device in relation to the associated linear encoder reader.
