Abstract

A rotary rivet dispenser for feeding slug rivets to an injector mechanism on the head of an automatic riveting machine. A rotary rivet slug container with an inner scoop aligns rivet slugs in the container for movement into a delivery tube by gravity feed assisted by intermittent air pressure.

Claims

1. A rotary dispenser of cylindrical objects comprising:

a housing, means for rotating said housing, a pickup tube within said housing and terminating at one end in a scope having a cradle thereon, said scoop being positioned against an inner wall of said housing for receiving said objects in the cradle thereof as said housing is rotated, said housing having a baseplate through which said pickup tube extends, said cradle having an arcuate cutout therein adjacent said baseplate whereby objects misaligned in said scoop and cradle fall out as said housing is rotated, said housing being rotatable about a nonhorizontal axis, said housing being rotatably and pivotally mounted on support arms on a mounting frame having an end of a delivery tube affixed thereto, said pickup tube having a lower end extending from said housing and along the rotational axis thereof, said pickup tube lower end being in alignment with said delivery tube upper end to pass said objects therethrough, said housing having an aperture therein, means projecting an airstream through said aperture upon each revolution of said housing, said scoop being at its uppermost position during its rotation when said airstream passes through said aperture to pressurize said housing and thereby propel objects on said cradle into said pickup tube.

2. A rotary dispenser as in claim 1 wherein said housing is also pivotally mounted on said mounting frame and wherein said housing may be pivoted to a vertical position with said pickup tube lower end extending upward, an object container cup detachably affixed to said housing to supply said housing with objects to be passed through said pickup tube, and wherein a lock crank releasably retains said housing in pivotal position wherein said pickup tube and said delivery tube are aligned.

3. A rotary dispenser as in claim 2 wherein said housing has spring-pressed detent means thereon, and said cup has an annular groove thereon, said detent means engaging said groove when said container cuP is positioned on said housing.
