A automatic storage and retrieval system such as can be used as a parking bay structure
is provided which comprises a hydraulically operated skip hoist system and which includes a skip hoist shaft and a skip which is hoistable up and down the shaft. A plurality of parking bays are located around the skip hoist shaft. A pair of shuttles are located on the skip and are moveable relative to the skip for positioning vehicles on and removing vehicles from the parking bays. The shuttles are located on a rotunda on the skip which is rotatable about a vertical axis for rotating the shuttles to align the shuttles with the parking bays surrounding the skip hoist shaft.pallet racking
(a) a plurality of storage bins arranged in spaced fashion in a first two-dimensional array, each bin having a first pair of engageable means on each side wall near a first end of the bin and a second pair of engageable means on each side wall near the opposite end of the bin;push back racking
(b) means for extracting any selected bin from the array by engaging that pair of engageable means on the selected bin located nearest the front of the array, the extracting means including a frame and parallel arms spaced apart by a distance greater than the bin width, the arms being capable of joint movement with respect to the frame in a direction perpendicular to the plane of the array to a limit position where the arms extend part way along the sides of a selected bin, each arm having associated therewith bin engaging means capable of movement along the arm and having retractable means for engaging the engageable means on any selected bin and thereby withdrawing that bin from the array and onto the frame; Share:
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 present invention relates to automatic storage and retrieval systems 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 system in which the extractor engages the bins along their sides for purposes of removal and reinsertion.drive in racking
