Definitions

  • ABSTRACT Apparatus and method for separating spool-shaped articles having defective flanges from similar articles which are substantially free from flange defects includes translating the articles in an axial direction over an opening of predetermined width less than the flange diameter between members supporting the article by contact at the flange perimeter, and rotating the articles about the core axis so that the articles with defective flanges are rotated into a position in which the flange dimension is insufficient for the flanges to support the articles. The defective articles thereby fall through the opening whereas the articles substantially free from flange defects will not.
  • the apparatus desirably includes track means which defines the opening, supply means for supplying the articles to the track for travel in an axial direction, and means, advantageously vibrational means, for moving and rotating the articles.
  • a T TOR/VEYS SPOOLING GAUGE AND REJECT SYSTEM This invention relates to devices for detecting peripheral defects in spool-shaped articles. In one of its aspects this invention relates to devices for separating spool-shaped articles having flanges with peripheral continuity from similar articles except having at least one flange with a peripheral defect.
  • one object of the present invention is to provide a relatively inexpensive device capable of detecting minor defects in flanges, which device is capable of separating articles with defective flanges from spool-shaped articles substantially free of flange defects.
  • Another object is to provide a relatively inexpensive device capable of accurately detecting defects in flanges of spoolshaped articles which device is relatively free from moving mechanical parts which are subject to mechanical failure.
  • Still another object of the present invention is to provide a relatively inexpensive device which is capable of efficiently checking a large number of spool-shaped articles to determine whether any of such articles have a peripherally defective flange and to separate those having such defects from those substantially free from defects.
  • Yet another object of the-present invention is to provide methods and apparatus for separating plastic spools which can be effectively used in packaging photosensitive elements from spools having flanges with significant peripheral defects.
  • spool-shaped articles having an axially extending core and substantially completely formed flanges extending radially therefrom are separated from similar articles except having at least one peripherally defective flange, by moving the articles in an axial direction over a reject opening of predetermined width (less than the normal flange diameter) between two support members which support the articles by contacting the flange perimeter, and, as such spools are moved, rotating the articles about their axis.
  • the defective articles are thus rotated into a position in which the flange diameter through the defect in the defective article is insufficient for the flange to be supported by the support members thereby letting the defective article fall through the opening.
  • Articles which are substantially free from flange defects are carried along the support members to a separate destination.
  • the apparatus advantageously includes a track means which includes support members which are mounted in spaced parallel relationship which defines the width of the reject opening and arranged to support the articles by their flanges for movement of the articles in an axial direction along the length of the opening, and means for rotating and moving the articles along the opening.
  • FIG. 1 is a perspective view of apparatus according to one highly advantageous embodiment of the present invention.
  • FIGS. 2, 3, and 4 are fragmentary cross sections through the apparatus showing successive positions of a spool having a defective flange as it moves through and is rejected by the apparatus;
  • FIG. 5 is a diagrammatic plan view of the apparatus of FIG. ll.
  • FIG. 1 depicts an apparatus for separating spool-shaped articles having defective flanges from similar spools which are substantially free from defects.
  • a bar of rectangular cross section, and 16 a plate having a substantially vertical surface 18, are mounted in spaced parallel relationship by end plates 20 and 22 to form a track.
  • the distance between edge 114 of support member 12 and sub stantially vertical surface 18 of support member 16 defines the width of reject opening 3% through which spools (or spoolshaped articles) with defective flanges fall.
  • Vibrator 32 is linked to support members 12 and 16 by rigid linking member 30.
  • Vibrator 32. is advantageously an in-line vibrator (e.g.,, Syntron in-line vibrator) which vibrates in the direction of arrow 26 as shown in FIG. 5.
  • Rigid linking member 30 connects support members 12 and 16 diagonally to the direction of vibration (also shown in FIG. 5) and skewed with respect to the plane of vibration.
  • the direction of vibration is thus skewed with respect to the plane of intended spool travel and thus applies a force which has longitudinal and transverse components in the intended plane of spool travel and a component perpendicular to the plane of spool travel. Accordingly, the spools are rotated about their axes and moved along the track. Vibrator 32 is fixed in position by vibrator mount 34', thus providing more accurate control of the extent and direction of the vibration.
  • Linking member 30 is advantageously mounted rigidly but adjustably to the support members. The slope of the plane of intended spool travel may thus be controlled by adjusting the slope of support members 112 and 16 so that gravity can assist the travel of the spools along the support members to a desired amount.
  • the extent of vibration and slope and length of the track is controlled to maximize efiiciency of the apparatus and to assure that the spools are rotated the desired amount for the specified length of the track and yet that the spools move along the support members at a rapid rate.
  • a slope of 10 to 30 from horizontal is usually sufficient with the ends of support members which are attached to facing member 20 being the higher end.
  • Support members 12 and 16 are attached to facing members 20 and 22 with corner 14 of the rectangular cross section of bar 12 pointed toward substantially vertical (within about 10) surface 18 so that the distance between corner 14 and surface 18 defines the width of reject opening 38.
  • the width of opening 38 can, of course, vary depending upon the size of the spool flanges and the radial dimension of the flange defect which is tolerated.
  • One of the outstanding advantages of the present invention is the ease with which the device can detect relatively minor flange defects and separate spools having such defects from completely formed spools.
  • corner 14 is, for example, spaced 0.975 inch from surface 118. It is quite apparent from the foregoing that for reli able separation of completely formed spools from incompletely formed spools, this distance should be carefully controlled to assure that the support members are parallel at least to within predetermined toleration limits.
  • spools are fed by feeder 10, which can be any type of mechanism that will orient spools for travel in an axial direction, for example, a Syntron bowl vibrational unit, through an orifice defined by end plate 20.
  • feeder 10 can be any type of mechanism that will orient spools for travel in an axial direction, for example, a Syntron bowl vibrational unit, through an orifice defined by end plate 20.
  • vibrator 32 which is linked to support members 12 and 14 by rigid linking member 30, applies a force which is skewed with respect to the plane of intended spool travel.
  • the spools are thereby moved in an axial direction away from the supply means, or orifice in facing member 20, along support members 12 and 16 and are rotated about their axis.
  • the spools having no significant peripheral defects are advantageously rotated at least 360 during the travel along the track defined by support members 12 and 16.
  • Completely formed spools, spools with no significant peripheral defects are fed by the track through facing member 22 at exit opening 24 to the desired receptacle.
  • a spool having at least one incompletely formed flange, (a flange with a peripheral defect, as flange 13) is supported in a manner similar to spools with completely formed flanges, as shown in FIG.
  • An apparatus for separating spool-shaped articles having respective axially extending cores and at least two extending completely formed circular flanges attached to said respective cores and extending radially therefrom from similar articles which have peripherally incompletely formed flanges said apparatus comprising, in combination:
