An inserter/extractor apparatus for inserting and extracting objects from bins located at different heights in a carousel including a vertical frame and an inserter/extractor carriage that is vertically movable along the frame and has a pair of gripping pads that have opposed, high friction gripping surfaces. The gripping pads are movable along a first horizontal axis from a retracted position in which said gripping pads and carriage are free to move vertically along the frame without interference with the bins to an extended position in which the gripping pads are even with a bin. The gripping pads are movable with respect to each other along a second horizontal axis that is transverse to the first horizontal axis from open positions spaced from each other by a distance larger than the largest dimension of an object to positions spaced from each other by a distance less than the smallest dimension for an object. The gripping pads apply a predetermined force to an object between them when stopped from further movement along the second horizontal axis by the object between them.

An inserter/extractor and carousel apparatus for inserting and extracting boxes from bins located at different heights comprising a frame that faces said bins and extends vertically along said heights, and an inserter/extractor carriage that is vertically movable along said frame to positions corresponding to said heights, said carriage including a pair of gripping pads that have opposed, high friction gripping surfaces of sufficient area to engage the sides of boxes therebetween and are carried by said carriage, said gripping pads being movable along a first horizontal axis from a retracted position in which said gripping pads and carriage are free to move vertically along said frame without interference with said bins to an extended position in which said gripping pads are even with a said bin, said carriage including means for moving said gripping pads with respect to each other along a second horizontal axis that is transverse to said first horizontal axis from open positions spaced from each other by a distance larger than the largest dimension of a said box to positions spaced from each other by a distance less than the smallest dimension for a said box, said gripping pads applying a predetermined force to a said box between them when said gripping pads are stopped from further movement along said second horizontal axis by said box between them, further comprising a carousel of said bins, said carousel comprising tracks providing a path of travel in an endless loop, said loop having an insertion/extraction station at which said bins face said frame, vertical support members disposed on said tracks for travel around said loop, vertical groups of bins, each bin being respectively connected to said vertical support members at different heights along respective vertical axes, each said bin having a back wall, two side walls, and a substantially flat, straight and immovable shelf that extends from said back wall to a location substantially in front of said side walls in cantilever fashion beyond said side walls so as to permit said gripping pads to move over a portion of said shelf that extends beyond said side walls without contacting said side walls and to grip portions of said boxes extending beyond said side walls over sufficient area so as to be able to frictionally engage said sides of said boxes and slide said boxes over said shelves along said first axis, said gripping pads being movable along said second horizontal axis over said shelf at said location from positions outside of said side walls to positions at the sides of said box so as to frictionally engage the sides of a said box.
