Abstract:
1. A load storage apparatus comprising: a rack including at least one load support, the load support including a detection part; a transferrer including a carrier for transferring loads to and from the load support of the rack by means of transfer that includes movement relative to the load support of the rack, the carrier including a load supporting plate and a detector; the detector for detecting the detection part of the load support of the rack; and a learning system; wherein the learning system measures a distance for which the carrier moves from a reference position toward the load support until the detector detects an associated detection part; wherein the leaning system, based at least in part on the measured distance, computes a distance for which the carrier moves from the reference position to a position to load and unload the load support; wherein the learning system stores the computed distance as a learned distance for the load support; and wherein the carrier can move on the basis of the learned distance to operate for the load support; and wherein the detector is fitted detachably to the load supporting plate of the carrier so as to be detached except for a time of learning operation; and a positioner for positioning a load on the carrier, the positioner capable of positioning the detector on the carrier.
