An object moving system (60) having a frame (62), an object movement imparting assembly (76) having at least a first part (78) through which an object (68) can be moved and a second part (80), a plurality of pulleys (122,124,126,128,130) on the object movement imparting assembly, first and second drives (104,106) each selectively operable in forward and reverse directions, and an elongate drive element (112). The object movement imparting assembly is guided selectively in first and second opposite directions (82,84) in first and second paths relative to the frame. The first part of the object movement imparting assembly is guided selective in third and fourth opposite directions (86,88) in third and fourth paths relative to the second part of the object movement imparting assembly. The first and second paths are transverse to the third and fourth paths, respectively. The elongate drive element is trained around the plurality of pulleys and operably connected to the first and second drives so that simultaneous operation of the first and second drives and variation of the drive directions of the first and second drives allows the elongate drive element to be moved so as to cause the object movement imparting assembly to move in the first and second paths and the first part of the object movement imparting assembly to move in the third and fourth paths to thereby controllably reposition an object through the first part of the object movement imparting assembly. <IMAGE> |
