Definitions

  • Appl' (L915 Strip feeding apparatus of the kind in which a pair of opposed rollers successively flex toward each other opposed regions of 52] CL 242/210 242/192 242/195 the flange members of a rotating reel as those regions are 51] Int Cl Gubls/66 lb 15/32 respectively rotated past the rollers, includes a pair of flange- Field of Search I i I l 242/192, flexing rollers which are movable relative to each other to vary the distance therebetween and thereby provide flexing engagement selectively with reels of difierent flange member spacing.
  • the present invention relates to the unwinding of strip material from a reel or other support for use at a predetermined location and, more particularly, to apparatus for supporting rolls of convoluted strip material of different widths and for feeding a leading strip portion from a roll so supported. Moreover, this invention relates to strip handling apparatus of the kind which transversely flexes successive regions of the outermost convolution of a roll of strip material to effect feeding of the leading strip end along a guide path from such roll and which is improved to handle strip material of different widths.
  • This localized flexing of the reel flanges imparts a transverse pinching force to successive portions of the outermost convolution of strip material wound on the reel and, thereby, causes the outermost strip convolution to rotate with the reel.
  • this localized pinching of the outermost strip convolution bows it transversely, thereby causing the pinched strip portion to assume a longitudinally straight condition due to resistance of the strip material to be flexed simultaneously both along and transverse to its longitudinal axis.
  • the pinching of successive trailing portions of the outermost strip convolution thus causes the leading end to move tangentially outward from the strip roll and into contact with a generally annular strip guide surface of the magazine. Because successive portions of the outermost strip convolution are continuously held between successive opposed regions of the reel flanges, the leading strip end is moved with the rotated reel and along the strip guide surface. As the leading end of the strip is moved in contact with this guide surface, it is directed by such surface to an exit channel in the magazine and passes therethrough for use at a predetermined location.
  • strip feeding apparatus of the kind previously described has been recently devised for use with a plurality of strip bearing reels of respectively different flange member spacing.
  • This last-mentioned strip feeding apparatus is disclosed in commonly assigned copending U.S. Pat. application Ser. No. 730,523 and achieves its versatility by means of a roller assembly on which is disposed several pairs of opposed rollercam surfaces. The cam surfaces comprising the individual pairs of such surfaces are spaced apart by different predetermined distances respectively corresponding to the different predetermined widths of strip material intended for use.
  • roller assembly is mounted so that each pair of roller-cam surfaces can be moved along a path substantially normal to the axis of rotation of a selected reel for flexing engagement of a cam surface pair, in the manner previously described, with the spaced flange members of a particular strip bearing reel to which such pair corresponds. While this strip feeding apparatus is adapted for use with strip material of different widths, it will be appreciated that the adaptability of such apparatus as to the number of different width strips that can be handled thereby is generally limited to the number of discrete pairs of cam surfaces disposed on the roller assembly.
  • Another important object of the present invention is to provide an improved strip handling apparatus for feeding strip material from a reel to a location spaced from the reel, such apparatus being adapted for use with reels whose respective flange members are spaced apart from one another by different distances so that each reel can support strip material of a corresponding different width.
  • Still another object of the present invention is to provide a strip handling apparatus of the kind which transversely flexes successive regions of the outennost convolution of a roll of strip material to effect feeding of the leading strip end along a guide path from the roll and which is improved over such apparatus heretofore known to provide a greater versatility regarding the number of different width strips that can be handled thereby.
  • a strip feeding apparatus of the kind in which successive opposed regions of the flanges of a reel rotating in an unwinding direction are flexed toward each other to impart a transverse pinching force to successive portions of the outermost convolution of strip material wound on the reel, is provided with an improved structure adapted to perform the foregoing flange-flexing function upon several reels of respectively different flange spacing.
  • This improved structure comprises a pair of opposed flange-flexing members movable relative to each other to vary the distance therebetween for engagement selectively with the differently spaced flanges of the various reels. Furthermore, the pair of flange-flexing members are biased for movement toward each other so that when such members are respectively engaged with the flanges of a rotated reel successive flange regions of the reel will be flexed toward each other to effect strip feeding.
  • FIG. I is a plan view of the improved strip feeding apparatus according to a preferred embodiment of the present invention illustrated in cooperation with a magazine-reel unit in which is wound, on the reel, a roll of strip material of a first width;
  • FIG. 2 is a partial front elevation view of the strip feeding apparatus and magazine-reel unit shown in FIG. 1, cross-sectioned along the line 2-2 of FIG. 1 and showing a novel roller assembly of the apparatus in a position to effect feeding of the leading strip end off the reel;
  • FIG. 3 is a partial front elevation view of the roller assembly depicted in FIG. 2, showing the position of such assembly upon initial contact with the reel;
  • FIG. 4 is a partial front elevation view of the roller assembly previously shown, though illustrated in cooperation with a reel whose flanges are spaced apart to support a roll of strip material of a second width which is narrower than the first strip width depicted in FIGS. 1-3 and showing the position of such assembly upon initial contact with the reel;
  • FIGS. 5 and 6 are partial front elevation views similar to FIG. 4 showing the roller assembly as it moves upon rotation of the reel from the initial position shown in FIG. 4 to the strip feeding position shown in FIG. 6;
  • FIGS. 7 and 8 are partial front elevation views of the improved strip feeding apparatus according to a modified embodiment of the present invention illustrated in cooperation with a reel whose flanges are spaced apart to support a roll of strip material of a third width which is intermediate the first and second strip widths respectively depicted in FIGS. 1-3 and 4-6, showing a modified roller assembly as it moves upon rotation of the reel from the initial position shown in FIG. 7 to the strip feeding position shown in FIG. 8.
  • FIGS. 1 and 2 there is shown one embodiment of a strip feeding apparatus 10, certain features of which are more fully disclosed in commonly assigned copending U.S. Pat. application Ser. No. 730,523, entitled Film Threading Apparatus, filed in the name of Elmer O. Wangerin on May 20, 1968, now U.S. Pat. No. 3,556,435, and commonly assigned U.S. Pat. No. 3,528,628.
  • those features of the apparatus 10 which have heretofore been disclosed include a strip supply reel spindle 11 rotatably mounted on a stationary support plate 12 and a strip guide channel 13 defined by opposed wall members 14 and 15 and by idler roller 16.
  • Such a unit 17 comprises a strip supply reel 18 of the standard type laterally enclosed by a magazine 19 provided with an internal rib 20 projecting inwardly from and spaced between the peripheral edges of the upper and lower flange members 21 and 22 of the reel.
  • a cylindrical strip guide surface 23 of the rib 20 laterally surrounds a roll of convoluted strip material 24 wound about the hub member 25 of the reel 18 between the reel flanges 21 and 22. As shown in FIG. 1 this surface 23 surrounds the convoluted strip roll 24 except in the region of a strip exit throat 26, which extends through the magazine 19 to define the only passageway through which strip material can be fed from the reel 18.
  • the reel 18 When the magazine-reel unit 17 is installed on the strip feeding apparatus 10, the reel 18 is supported by the spindle 11 and is engaged by the spindle splines 27 so that rotation of the spindle is imparted to the reel. Furthermore, opposed support lugs 28 and 29 located on the support plate 12 receive a base portion 30 of the magazine 17 therebetween to maintain the magazine in a fixed position in which it is concentric with the reel 18 and in which the strip exit throat 26 is aligned with a corresponding end of the strip guide channel 13.
  • FIGS. 1 and 2 a pair of 32. These members are located adjacent the installed magazine-reel unit 17 on a common axis of rotation parallel to the rotational axis of the spindle 11.
  • the pair of rollers 33 and 34 of the idler assembly 32 are mounted for rotation about a shaft 35 and are resiliently biased to move along the same shaft toward each other and toward a shaft lug 36 (separating the rollers) by helical compression springs 37 and 38.
  • the roller shaft 35 is supported by spaced bars 39 and 40 which are pivotally connected to the stationary plate 12 by a connecting rod 41. Accordingly, the roller assembly 32 can be pivoted within the confines of a plate aperture 42 and can be likewise pivoted in a manner such that the upper and lower rollers 33 and 34 are movable into and out of lateral engagement with the peripheral edges respectively of the upper and lower reel flanges 21 and 22 of the installed magazine-reel unit 17.
  • a helical tension spring 43 interconnecting the plate 12 and the roller assembly 32 resiliently biases the assembly for such pivotal movement toward the installed magazine-reel unit 17, but otherwise allows the roller assembly to be manually pivoted away from the installed magazine-reel unit to permit removal of the unit from the spindle 11.
  • roller assembly 44 which is a modification of the roller assembly 32 shown in FIGS. I6 and whose like parts are referenced by the same numerals as in the example of the roller assembly 32.
  • the modified roller assembly 44 is generally distinguished from the previously described roller assembly 32 in that its lower roller member 45 is not movable along the roller shaft 35; but, instead, is rotatably mounted interjacent the shaft lug 36 and the support bar 40 which, in this instance, is located within a recess 46 in the stationary plate 12.
  • modified roller assembly 44 is mounted for pivotal movement about the rod 41 and is limited in such movement by the confines of plate recess 46 in much the same way as the roller assembly 32 is limited during pivotal movement thereof by the confines of plate aperture 42.
  • roller assemblies 32 and 44 are equally adapted for use with several strip bearing reels whose respective flange members are spaced apart from one another by different distances so that each reel can support strip material of a corresponding different width.
  • the flange members 21 and 22 of reel 18 are spaced apart from one another to support strip material 24 with a width of 35mm; whereas, in the magazine reel-unit 61 the flange members 47 and 48 of reel 49 (FIGS.
  • the magazines 19, 55 and 56 are each provided with a narrowed rib portion respectively shown as 58 in FIGS. l-3, 59in FIGS. 4-6 and 60 in FIGS. 7-8, which is laterally aligned with a corresponding pair of upper and lower reel flanges respectively shown as 21 and 22 in FIGS. 1-3, 47 and 48 in FIGS. 4-6 and 51 and and 52 in FIGS. 7-8.
  • These narrowed rib portions are disposed on the magazines so that when a magazinereel unit is installed on the strip feeding apparatus 10 in the manner previously described such portion will be located adupper and lower roller members 33 and 34 of a roller assembly jacent the pair of rollers of a roller assembly.
  • the installed magazineyreel unit 17 is located with its narrowed rib portion 58 adjacent the roller members 33 and 34 of roller assembly 32. Accordingly, the roller members of a roller as sembly can be moved past the narrowed magazine rib portion of an installed magazine-reel unit to contact opposed peripheral regions of the reel flanges of such unit.
  • the pair of rollers 33 and 34 are provided with two opposed conical surfaces 63 and 64 coaxial with the roller shaft 35 and divergent with respect to each other outwardly from the shaft.
  • the influence of spring 43 acting on the roller assembly 32 serves to position the assembly so that the conical surface 64 of the lower roller 34 (once moved past the narrowed magazine rib portion 59) is in flexing contact with the peripheral edge of the lower flange member 48 of the reel 49, see FIG. 4.
  • roller as sembly 32 Upon continued driving rotation of the reel 49, roller as sembly 32 is progressively moved by the force of spring 43 toward the reel so as to continually induce the lower roller 34 to be further lowered along the roller shaft 35 until opposed cylindrical lip surfaces 67 and 68 of the upper and lower rollers 33 and 34 engage and, thereby, flex toward each other successive opposed peripheral regions of the reel flanges 47 and 48, see FIG. 6.
  • the upper and lower flange members of reel 49 are flexed toward each other because of the combined urging of spring 43 on the roller assembly 32 and the opposed urging of springs 37 and 38 on the upper and lower rollers 33 and 34.
  • the leading strip end will be fed along the strip guide surface 23 of the magazine and, thence, successively through the strip exit throat 27 and the strip guide channel 13 to a predetermined location (not shown) at which the strip material 50 can be utilized for its intended position, see FIG. 1.
  • the pair of rollers 33 and 34 will continually move away from each other along the roller shaft 35 (against the opposed urging of springs 37 and 38) as the roller assembly 32 is progressively moved by the force of spring 43 toward the rotating reel.
  • their respective cylindrical lip surfaces 67 and 68 engage and, thereby, flex toward one another successive opposed peripheral regions of the reel flanges 21 and 22 so that the leading end of 35mm strip material 24 will be fed from the rotating reel as shown in FIG. 1 and fully described hereinbefore.
  • both the upper and lower roller members 33 and 45 of the modified roller assembly 44 are adapted to make initial contact respectively with the upper and lower reel flanges of an installed one of the 8mm, 16mm and 35mm strip bearing magazine-reel units 61, 62 and 17 so that the upper roller member can be raised along the roller shaft in the manner previously described; whereas, for the same purpose, only the lower roller member 35 of the roller assembly 32 need make initial contact with the lower reel flange of an installed magazine-reel unit, as illustrated by the example shown in FIGS. 4-6. Consequently, the lower roller member 45 of the modified roller assembly 44 is shown in FIGS.
  • modified roller assembly 44 might be adapted to flex only the upper flanges 47, 51 and 21 of the reels 49, 53 and 18, in whichcase the lower reel flanges 48, 52 and 22 could be supported by a substantially flat (as opposed to conical) annular roller member (not shown) of the same assembly.
  • strip feeding apparatus of the kind which transversely flexes successive regions of the outermost convolution of a roll of strip material to effect feeding of the leading strip end along a guide path from the roll and which is improved over such apparatus heretofore known to provide a greater versatility regarding the number of different width strips that can be handled thereby.
