This invention relates generally to the field of mechanical systems for providing reciprocating, linear motion for a movable structure or work piece relative to a fixed structure or work piece. More particularly, the invention relates to a drive mechanism providing reciprocating, linear motion from rotational motion of a motor, using a novel cable or wire rope drive mechanism. The invention is susceptible to many possible uses and installations, examples being drive systems for use in automated instruments for processing biological samples, and stacking systems for stacking cards or card-like bodies in a tray, which happen to be of particular applications presently employed by the present inventors. However, other possible uses of the invention in different types of machines and systems will be apparent to persons skilled in the art from the following detailed description, and thus the invention relates, primarily, to reciprocating drive mechanisms for a moveable work piece. [0002]

Drive mechanisms for providing reciprocating, linear movement of a moveable work piece relative to a stationary work piece or structure are known. An example is described in the patent of Clifford W. Karl et al., U.S. Pat. No. 5,674,454, assigned to the assignee of the present invention. Generally, the "454 patent describes a stacking system for stacking flat, thin, card-like objects in a magazine. The stacking system has a moveable push plate that is used to stack the objects in the magazine. In FIG. 7 of this patent, a motor has a pinion gear with teeth which engage complementary teeth of a push rack that is coupled to the push plate. The rotation of the motor causes the push rack to move back and forth in a linear fashion, causing a push plate to move back and forth relative to the magazine and thereby providing a mechanism for stacking the objects in the magazine. [0004]

Other drive systems known in the art include Levine et al., U.S. Pat. No. 5,854,075, which describes a drive belt system for moving a carriage assembly relative to a magazine containing a plurality of slides. Other patents describing belt-type drive systems include Seto et al., U.S. Pat. No. 5,660,793; and Shindo et al., U.S. Pat. No. 5,470,533. Porte et al., U.S. Pat. No. 5,073,342, describes a simple reciprocating piston-acruated transfer mechanism. Forsstrom, U.S. Pat. No. 3,221,781 contemplates a similar type of arrangement for moving sample carriers about an analytical instrument. Other reciprocating belt and paddle-based drive mechanisms are described in the patent of William E. Seaton et al., U.S. Pat. No. 5,736,102, which is also assigned to the assignee of the present invention. [0005]

While the drive mechanism of the type described in the above-cited are work satisfactorily for many applications, the present invention is considered to be an improvement over these and other types of systems. The present drive mechanism and method is believed to provide improved reliability in extended use, and decrease the amount of maintenance for the user. Further, the design is quiet in operation. The design is easy to assemble and less costly to manufacture than systems based on the design of the above-cited Karl et al. patent. [0006] SUMMARY OF THE INVENTION

In a first aspect, a drive mechanism for providing reciprocating, liner motion for a movable work piece relative to a stationary work piece is provided. The drive system includes a motor rotating a drum in forward and reverse directions about a first fixed axis. The motor is fixedly mounted with respect to the stationary work piece, such as to a housing or other structure. The system further includes an elongate, substantially non-flexible cable having first and second ends, which are fixed with respect to the stationary work piece. The cable, which in a preferred embodiment takes the form of a wire rope, further comprises an intermediate portion extending between said first and second ends, with the intermediate portion being wound around the drum. [0007]

The drive mechanism of the invention can be installed in any type of system that may benefit from quiet, reliable operation of a reciprocating linear drive mechanism. Preferred embodiments would be in automated biological sample testing instruments, and in stacking systems for flat, thin card-like objects. However, the invention is not limited to such systems. [0010]

In another aspect of the invention, a method is provided for moving a moveable work piece relative to a stationary work piece using an elongate, substantially non-flexible wire rope or cable, the cable having a first end and a second end and an intermediate portion between the first and second ends. The method includes the step of attaching the first and second ends of said cable to a structure fixed with respect to the stationary work piece. The method includes the step of winding the intermediate portion of the cable about a drum coupled to a motor, with the motor fixed with respect to the stationary work piece. The intermediate portion of the cable is further wound around the first and second bearings, with the first and second bearings mounted to the moveable work piece such that the first bearing is positioned between the first end of the cable and the drum and the second bearing is positioned between the second end of the cable and the drum. The method includes the step of rotating the drum, whereby the step of rotating causes the first and second bearings to move relative to the drum and thereby move the moveable work piece relative to the stationary work piece.[0011]
