Definitions

• FIG. 3 BY 1 A 7'TORNEYS COVER DISPENSER This invention relates to an improved apparatus for individually and separately dispensing a disc-shaped article.
• Another known machine has a plurality of rollers on which an edge of the disc shaped articles contact. The rollers rotate thereby rotating the contacting articles. Means in contact with the article stack move the articles longitudinally along the rotating rollers to a position at which dispensing means causes an individual article to be ejected from the article stack.
• This type of machine comprises a large number of moving parts that are subject to malfunction and breakage, are expensive and difficult to construct, and require considerable labor expenditures to properly adjust and maintain for uniform operation.
• FIG. 1 is a diagrammatic front view of the apparatus of this invention.
• FIG. 2 is a diagrammatic plan view of the apparatus shown in FIG. 1.
• FIG. 3 is a diagrammatic sectional view taken along lines III-III of FIG. 2.
• the improved apparatus has a frame 2 with spaced-apart first and second sidewalls 4, 6.
• a power source 8 is associated with the frame 2 and connected to a roller 10.
• the roller 10 has a longitudinal axis, first and second ends 12, 14, and extends between the sidewalls 4, 6 of the frame 2.
• the roller is operably connected to the power source 8 and rotatably attached at the first and second ends 12, I4 to the respective sidewalls 4, 6 for rotation about the longitudinal axis by the power source 8.
• a stabilizing rod 16 with first and second ends 18, 20 is attached to and extends between the spaced-apart respective sidewalls 4l, 6 of the frame 2.
• the roller 10 (better seen in FIG. 3) is positioned at a lower elevation than the stabilizing rod 16, laterally spaced therefrom, and is substantially parallel to said rod 16.
• a guiding rod 22 having first and second ends 24, 26 is attached at the first end 24 to the first sidewall 4, extends substantially parallel relative to the roller 10 toward the second sidewall 6, and terminates at the second end 26 at a location spaced from the second sidewall 6 a distance in the range of between one to less than two times the thickness of a single disc 27 that is dispensed by the apparatus.
• the guiding rod 22 is at a higher elevation and is spaced a lateral distance from the roller 10 in an opposed direction from said roller 10 relative to the lateral displacement ofthe stabilizing rod I6.
• the guiding rod 22, roller 10, and stabilizing rod 16 are spaced relative to one another and to a disc-shaped object 27 such that the guiding rod 22 and roller 10 contact a circumferential edge ofa disc 27 positioned thereon and support said disc 27 as the stabilizing rod 16 contacts the edge and maintains said disc 27 against lateral movement in a direction from the roller I0 toward the stabilizing rod 16.
• the stabilizing rod I6 to function with maximum capabilities to prevent the above described lateral movement of the disc 27, it is preferred that the stabilizing rod 16 be within a horizontal plane passing through the center of a disc that is operably positioned upon the roller 10 and the guiding rod 22.
• the lateral and vertical displacement of the guiding rod 22 relative to the roller 10 is also dependent upon the diameter of the disc 27 to be dispensed by the apparatus.
• roller 10 and guiding rod 22 be relatively positioned such that a downwardly extending vertical plane passing through the center of a disc 27 separates the roller 10 and the guiding rod 22 and is laterally spaced from the guiding rod 22 a greater distance than said plane is spaced from the roller I0 and an angle as measured from the center of the disc 27 from the roller 10 to the guiding rod 22 is less than
• the guiding rod 22 supports a portion of the weight of each disc 27, provides greater flexibility in loading a plurality of stacked disc 27 upon the roller I0 and guiding bar 22, and maintains the moving discs 27 against lateral movement in a direction from the roller 10 towards the guiding rod 22.
• the roller 10 rotates the disc 27 in a direction from the roller 10 toward the guiding rod 22. Frictional forces exerted on the discs 27 by the guiding rod 22, when rotating the disc as described above, also causes the discs 27 to be urged toward the roller 10 thereby tending to prevent vertical movement of the discs 27 relative to the roller 10, excessive wear on or damage to the discs 27, and increases the force of contact between the discs 27 and the roller 10.
• each rod have a longitudinal axis and be rotatable about their respective longitudinal axis in response to movement ofa disc 27 in contact therewith.
• a ramp 28 having an upper surface 30 is preferably positioned between a second sidewall 6 and the second end 26 of the guiding rod 22 and attached to the second sidewall 6 of the frame 2 at the lower elevation than a disc 27 resting upon the roller 10 and extends downwardly therefrom.
• An improved apparatus for maintaining and individually dispensing a plurality of articles having a power source, a frame with spaced-apart sidewalls, and a stabilizing rod with first and second ends attached to and extending between the respective sidewalls of the frame for contacting and maintaining a plurality of disc-shaped articles against lateral movement in a direction from a roller toward the stabilizing rod, the improvement comprising:
• a single roller having a longitudinal axis, first and second ends, and extending between the sidewalls of the frame and being at a lower elevation than the stabilizing rod is connected to the power source and rotatably attached at the first and second ends to the respective sidewalls for contacting a circumferential edge of a plurality of articles and supporting and rotating said articles;
• a guiding rod having first and second ends and being at a higher elevation and laterally spaced a distance from the roller in an opposed direction from the roller relative to the stabilizing rod and in contact with and at a lower elevation than a portion of a disc-shaped article resting upon the roller is attached at the first end to the first sidewall, extends substantially parallel relative to the roller toward the second sidewall, and terminates at the second end at a location spaced from the second sidewall a distance in the range of between one to less than two times the thickness ofa single disc for contacting and supporting a plurality of disc-shaped articles moving in contact with the roller, guiding the articles toward the second sidewall, preventing lateral movement of the articles from the roller toward the guiding rod, and releasing individual articles for lateral movement by the roller to a location spaced from the apparatus.
• An apparatus as set forth in claim 1, wherein a downwardly extending vertical plane passing through the centerline of a disc supported by the roller and guiding rod separates the roller and guiding rod and is laterally spaced from the guiding rod a greater distance than said plane is spaced from the roller and an angle as measured from the center of the disc from the roller to the guiding rod is less than 3.
• An apparatus as set forth in claim 2, wherein the stabilizing rod is within a horizontal plane passing through the centerline of the disc.
• An apparatus as set forth in claim 1, including a ramp having an upper surface positioned between the second sidewall and the second end of the guiding rod is attached to the second sidewall of the frame at a lower elevation than a disc resting upon the roller and extends downwardly therefrom.
