Automatic Storage And Retrieval System For Warehouse
The present invention relates to an automatic storage and retrieval system for extracting
individual storage elements from locations in a two dimensional array and replacing each extracted element into any other vacant location in that array or in some other location, possibly a second two dimensional array opposed to the first array and spaced from it by a distance only slightly greater than the length of the element. The present invention specifically relates to a system in which the bins are engaged by the extractor element along their sides.. The automatic storage and retrieval system of claim 1 further including a second two-dimensional array of bins having at least one vacant location; wherein the control means causes the platform means to bring the selected, extracted bin to a position adjacent the vacant location in the second array and then directs the extracting means to insert the selected bin into the vacant location.
The automatic storage and retrieval system of claim 2 wherein the length of the chain drive is adjusted so that the limits of travel of the finger block means is substantially equal to the distance along the length of the bin between the pairs of engageable means.
control means for causing the platform means to move horizontally and vertically to a position with respect to the array where the extracting means is adjacent the selected bin; for then directing the arms to move toward and around the bin sufficiently to bring the retractable bin engaging means into alignment with the engageable means on the selected bin; for then causing the retractable bin engaging means to engage the bin; for then directing the extracting means to extract the selected bin from the array; and for then directing the platform means to move horizontally and vertically to another desired location with the selected bin.
The present invention relates to automatic storage and retrieval system in which elements such as storage bins are arranged in a densely packed, two dimensional array from which arrangement they are extracted in random or at lest irregular sequences. It specifically relates to such a automatic storage and retrieval system in which the extractor engages the bins along their sides for purposes of removal and reinsertion.
