Abstract:
In combination, a work piece positioning device for a robot and an adjustable shelving unit comprising:a shelf frame having an aperture therein for receiving at least one shelf; an elongated first member attached to the shelf frame adjacent the aperture and including a longitudinal channel therein having a C-shaped transverse cross-section; an elongated second member attached to the shelf frame adjacent the aperture, the second member being spaced from and parallel to the first member, the second member including a longitudinal channel therein having a C-shaped transverse cross-section; a shelf positioned in the aperture between the first and second members and including opposite first and second side edges adjacent the first and second members respectively; spring nut mounting means attached to the shelf adjacent the first and second side edges and inserted into spring biased frictional sliding engagement within the C-shaped channel of the first member and the C-shaped channel of the second member respectively so as to slidingly, pivotally, and releasably clamp the shelf in a given height and angular position relative to the first and second members; whereby the height and angle of the shelf with respect to the first and second members are adjustable by unclamping the spring nut mounting means from the first and second channel members and moving the shelf from a first position to a second position, thence clamping the spring nut mounting means to the first and second channel members.
