  • a drive mechanism indicated at 10 for providing reciprocating, liner motion for a movable work piece 12 relative to a stationary work piece or structure 14 is provided.
  • the drive mechanism includes a motor 16 rotating a drum 18 in forward and reverse directions about a first axis 20.
  • the motor 16 is fixedly mounted with respect to said stationary work piece 14, either directly or indirectly.
  • An elongate, substantially non-flexible cable such as a wire rope 22 is provided.
  • the wire cable 22 has a first end 24 attached to the stationary work piece 14 and a second end 26 which is also fixed with respect to the stationary work piece 14.
  • the cable 22 further comprises an intermediate portion 28 extending between the first and second ends 24 and 26.
  • the intermediate portion 28 is wound around the drum 18, for example with three wraps around the barrel of the drum as shown.
  • a first bearing 30 is coupled (e.g., fixedly mounted either directly or indirectly) to the movable work piece 12.
  • the first bearing is positioned relative to the cable such that the intermediate portion 28 of the cable 22 is wound over or around the first bearing 30.
  • the first bearing 30 is positioned along the cable 22 between the first end 24 of the cable and the drum 18, as shown in Figure 1.
  • a second bearing 32 is also coupled to the movable work piece 12. The second bearing is positioned relative to the cable 22 such that the intermediate portion 28 of the cable passes is wound over the second bearing 32 with the second bearing 32 being positioned along the cable 22 between the drum 18 and the second end 26 of the cable 22, as shown.
  • the cable is sufficiently stretched taught (or a tension spring 36 is installed) such that rotation of the drum 18 in forward and reverse directions moves the wire rope and hence the first and second bearings 30 and 32 relative to the drum 18, thus moving the moveable work piece 12 relative to the stationary work piece 14.
  • This action is shown in Figures 2A, 2B and 2C.
  • counterclockwise rotation of the drum 18 (as viewed from above) pulls the wire rope in a direction to cause the first bearing 24 to move closer to the drum 18 to the left, while reeling out more wire rope and allowing the second bearing 32 to move to the left as well. Since the first and second bearings 30 and 32 are mounted to the moveable work piece, the moveable work piece 12 of FIG.
  • a tension spring 36 is coupled to the first end of cable 22, applying a tension to the cable 22.
  • the tension spring 36 has a loop 38 which is anchored to a post 42.
  • the second end of the cable is anchored in any suitable fashion to the fixed work piece, such as by forming a loop in the end 26 of the cable and likewise placing it over a fixed post.
  • Figure 5 shows how the ends of the cables are formed in a presently prefe ⁇ ed embodiment, with the first end 24 having a metal eye 44 that is swaged or crimped onto the cable 22, and the eye 42 hooks onto the end of the tension spring 36 of FIG. 2A.
  • FIG. 3 is a perspective view of an embodiment of the invention in which the reciprocating drive mechanism 10 of the present invention is used to move a push plate 50, connected to the reciprocating or moveable work piece 12, back and forth to stack cards or card-like objects in a magazine.
  • the overall magazine support structure is shown in FIGs. 14 and 15 and will be described subsequently.
  • the drive system 10 is intended to replace the rack and pinion reciprocating drive mechanism described in the Karl et al. patent, U.S. Patent No. 5,674,454, cited previously.
  • the motor 16 comprises a stepping motor whose operation is governed by firmware or software for the stacking disposal system, the details of which are not particularly pertinent.
  • the motor 16 is mounted by means of a set of screws 52 to a stationary motor mount assembly 54 comprising the fixed or stationary part of the drive system.
  • the motor mount assembly 54 includes flanges 56 with screw holes 56 that are used to mount the entire drive system 10 to the instrument incorporating the stacking assembly.
  • FIG. 3 also shows as optical interrupt sensor 60 that is incorporated at the top of the upper portion of the motor mount assembly 54.
  • the optical interrupt sensor 60 detects when a portion of the moveable paddle mount 12 has traveled sufficiently towards the left in the FIG. 3 such that the extreme left-hand portion of the paddle mount passes in-between the detector and emitter of the sensor 60. This signifies that the motor 16 has moved the paddle mount 12 and push plate 50 to a home position (or, equivalently, any given predetermined position).
  • FIG. 3 also shows an overtravel stop screw 62 that is placed directly above the moveable paddle mount 12. As shown best in FIG. 4, as the motor 16 drives the paddle mount 12 to the right, the corner 66 of the paddle mount 12 abuts the stop screw 62, preventing further movement of the paddle mount and paddle 50 to the right.
  • FIGs. 3 and 4 also show a lower post 64 fixed with respect to the motor mount assembly 54. The loop 46 (FIG. 5) in the second end 26 of the cable 22 is placed over the lower post 64, thereby fixing the second end of the cable 22.
  • FIG. 3A illustrates in simplified form the operation of the structure of FIG. 3.
  • FIG. 6 is a partially exploded view of the drive system of FIG. 3.
  • the moveable work piece or paddle mount 12 carries the two bearings 30 and 32, and the push plate or paddle 50 is in turn mounted to the paddle mount 12.
  • the paddle mount 12 is mounted to a translating portion 80 of a linear bearing 82 by means of screws 72.
  • the linear bearing 82 comprises a stationary portion 84 that is attached to the motor mount assembly 54 by means of screws 74 and the translation portion 80.
  • the translating portion 80 of the linear bearing 82 can translate back and forth along a direction defined by the groove 86 in the stationary portion 84.
  • the bearings 30 and 32 each comprise a two-piece flanged ball bearing that is affixed to the moveable work piece or paddle mounting plate 12 by means of a screw or other equivalent type of fastening means 70 and a lock washer 90. It will be apparent from FIG. 7 that the linear bearing 82 and paddle mounting plate 12 must be secured in place to the motor mount assembly 54 prior to the insertion of the motor 16 into the motor mount assembly 54, as the drum 18 fits in front of the paddle mount 12 with the paddle mount 12 sandwiched between the drum and the rear face or wall 92 of the motor mount assembly 54 when the entire unit is assembled.
  • FIGs. 8 and 9 are additional perspective views of the entire drive mechanism in an assembled condition, with the cable 22 of FIG. 3 omitted for purposes of better illustrating the rest of the components of the system 10.
  • FIG. 10 is an end view of the assembled drive system 10 (without the cable 22) as seen from the left hand side of FIG. 3, looking toward the sensor 60 and the rest of the components.
  • FIG. 11 is another side elevational view as shown in FIG. 4, but with the cable omitted in order to better illustrate the rest of the components.
  • FIG. 12 is a top plan view of the drive mechanism 10 of FIGS. 3-11.
  • FIG. 13 is a bottom plan view of the drive mechanism 10. Referring now to FIGs.
  • the drive system 10 is used to move the push plate 50 back and forth, so as to push a test sample card 100 into a removable magazine (not shown) for storing the cards 100.
  • the magazine rests on a magazine support assembly 102.
  • a spring loaded bar 104 keeps the cards that have been loaded into the magazine stacked in the magazine.
  • the drive system 10 operates in a forward direction to move the push plate 50 towards the bar 104, and in the process moves the test sample card placed immediately in front of the push plate over a pair of resilient snap elements in the side of the magazine, and into a stacked condition in the magazine, as described in the Karl et al. '454 patent.
  • the present invention provides smoother, quieter and more reliable operation of the drive system for the push plate 50, reduces user maintenance of the drive system, and is considered easier to manufacture and less costly as compared to alternative prior art designs. Further details on the construction and operation of the magazine support structure 102 and the stacking process for stacking cards are set forth in the Karl et al. '454 patent.
  • the method comprises the step of attaching the first and second ends of the cable to a structure fixed with respect to the stationary piece 14/54, as indicated by making loops in the end of the cable and securing the loops to posts 42 and 64 as indicated in FIG. 4, either directly or with the use of a tension spring 36.
  • the method further includes the step of winding the intermediate portion of the cable 22 about a drum 18 coupled to a motor 16, with the motor fixed with respect to the stationary piece 14/54 as indicated in FIGS. 4 and 14.
  • the method further includes the step of further winding the intermediate portion of the cable 22 around first and second bearings 30 and 32.
  • the first and second bearings 30 and 32 are mounted to the moveable work piece 12 (as shown in FIG. 6), such that the first bearing 30 is positioned relative to the cable 22 between the first end 24 of the cable 22 and the drum 18 and the second bearing 32 is positioned relative to the cable 22 between the second end 26 of the cable 22 and the drum 18.
  • the method includes the step of rotating the drum 18 (as indicated in FIGS. 2 A, 2B and 2C), whereby the step of rotating causes the first and second bearings to move relative to the drum and thereby move the moveable work piece 12/50 relative to the stationary work piece 14/54.
  • drum 18 rotates about a first axis 20 (FIG. 2A). As shown in
  • the cable is wound about the first and second bearings 30 and 32 such that rotation of the drum 18 about the first axis 20 causes the moveable work piece 12/50 to move in a linear direction defined by the linear bearing 82 of Fig. 7 in a direction that is orthogonal to the first axis, i.e., the axis of the motor 16 and drum 18.
  • the moveable work piece 12/50 piece reciprocates back and forth along a path defined by the linear bearing 82, and rotation of the drum 18 in clockwise and counterclockwise directions causes the moveable work piece 12/50 to translate back and forth along the path defined by the linear bearing 82.
  • the method of the present invention includes the step of providing an optical sensor 60 in close proximity to the moveable work piece 12, and detecting with the optical sensor 60 the position of the moveable work piece 12/50 relative to the stationary work piece 14/54 to thereby detect when the moveable work piece has reciprocated in the path back to a predetermined or home position.
  • the present invention is not considered limited to the illustrated embodiment. Rather, the principles of operation of the invention are applicable to other mechanical systems having the need for linear reciprocating motion. While the presently contemplated best mode for practicing the invention is in the context of stacking test sample cards, the invention can be used for stacking other types of substantially flat and thin card-like objects. Other drive systems found in automatic biological sample testing instruments are possible candidates for implementation of the invention. Accordingly, the true scope of the invention is to be determined by reference to the appended claims, interpreted by the foregoing description.

Abstract

L'invention concerne un mécanisme d'entraînement permettant d'obtenir un mouvement linéaire de va-et-vient pour une pièce à usiner mobile par rapport à une pièce à usiner fixe. Le système d'entraînement comprend un moteur faisant tourner un tambour dans les sens avant et arrière autour d'un premier axe. Le moteur et le tambour sont montés fixes par rapport à la pièce à usiner fixe, tels que par rapport à un logement ou à une autre structure. Le système comprend également un câble long sensiblement non flexible présentant une première et une seconde extrémité fixées par rapport à la pièce à usiner fixe. Le câble comprend également une partie intermédiaire s'étendant entre les première et seconde extrémités, la partie intermédiaire étant enroulée autour du tambour. Des premier et second paliers sont prévus lesquels sont montés sur la pièce à usiner mobile. Le premier palier est positionné par rapport au câble de manière que la partie intermédiaire du câble soit enroulée sur le premier palier, et le premier palier étant positionné entre la première extrémité du câble et le tambour. Le second palier est positionné par rapport au câble de manière que la partie intermédiaire du câble soit enroulée sur le second palier, le second palier étant positionné entre le tambour et la seconde extrémité du câble. La rotation du tambour dans des sens soit dextrorsum soit senestrorsum fait déplacer au câble les premier et second paliers vers l'arrière et vers l'avant par rapport au tambour, provoquant ainsi un mouvement de va-et-vient linéaire de la pièce à usiner mobile par rapport à la pièce à usiner fixe.
