Definitions

  • the present invention relates to the feeding of rivets or other fasteners or similar articles to riveting or other fastener inserting means.
  • the rivet blanks having heads at one end of each are commonly fed to the riveting apparatus by passing them downwardly through a feed tube and thence laterally to rivet receiving fingers which support the same and insert them through holes in workpieces to be riveted. Passage of the rivet blanks downwardly through the feed tube may be by gravity alone or by air pressure against rivet blanks downwardly through the feed tube.
  • the individual rivets are fed usually downwardly through a feed tube and come to rest upon side rail formations from which they are moved laterally to conventional rivet holding fingers.
  • the present invention provides means to prevent cocking of rivet blanks in the feed tube which interferes with feeding thereof and also makes it possible to employ the rivet feeding mechanism in any orientation, including an upside-down orientation with respect to conventional downwardly moving rivet blanks.
  • the present invention relates entirely to means for preventing cocking of the rivet blanks in their passage through the feed tube and insuring their axial alignment regardless of the position or orientation of the feed tube.
  • an air jet arrangement which surrounds the feed tube and includes a series of circumferentially spaced air passages which are each directed angularly toward the feed tube axis and in the direction of movement of the individual rivets whereby they form a conical air pressure pattern which acts against the shanks of the individual rivets and thus maintains them in axial alignment in the feed tube.
  • Fig. 1 the numeral 10 designates generally the upper anvil structure of a riveting machine which structure is conventional and well known.
  • the anvil., per se, is designated 11 and extends downwardly into a pair or rivet receiving fingers 12 which is likewise conventional in the riveting machine art.
  • the individual rivets, designated 13, are moved laterally to a position between the fingers 12 with the heads of the rivets uppermost and the shank portions extending downwardly as shown in dot and dash lines at 13 in Fig. 1.
  • the position of individual rivets prior to their horizontal movement to the rivet fingers is shown in full lines in Fig. 1.
  • the present invention provides means to maintain individual rivets in vertical alignment and prevent cocking thereof in the feed tube and also provides for feeding rivets in proper axial orientation in any position of the rivet feeding mechanism, including an upside-down position in which case the rivets would be blown upwardly through the feed tube 15 by air pressure.
  • Fig. 3 As illustrated in Fig. 3 on a somewhat enlarged scale the lower end of tube 15 fits within a collar 16 the interior of which forms a continuation of the feed tube 15. Collar 16 is supported upon a horizontally extending bracket 18 which is attached to the riveting machine. Referring particularly to Fig. 1, rivets 13 having heads at their upper ends drop downwardly so that the rivet heads normally rest upon spaced ledges 20 formed by a slot 21 in bracket 18 as shown in Fig. 2.
  • a bar 24 is longitudinally slidable in slot 21 and has a V-shaped nose portion 25 adapted to engage successive rivets on ledges 20 and move them horizontally to engagement with conventional receiving fingers 12.
  • Bar 24 is fixed to a piston 26 and an air pressure connection 27 moves piston 26 and bar 24 against the resistance of a coil spring 28.
  • the novel portion of the present rivet feeding apparatus is best shown in Figs. 3 and 4 and in the present instance takes the form of a beveled annular groove 30 in collar 16 and a series of circumferentially spaced downwardly extending angular passages 31.
  • the beveled groove 30 is closed by a collar 32 and a source of air pressure is introduced to groove 30 by a connection 33.
  • air is projected in a downwardly conical path as shown by the dot and dash lines in Fig. 3 and impinges against the shanks of rivets 13 to urge such shanks toward a coaxial position with respect to feed tube 15 and collar 16.
