ASYMMETRIC ARTICLE HANDLING AND ORIENTATION
First Claim
1. An article handing apparatus comprising a puck for handling articles of asymmetric configuration wherein said puck includes:
- an upper puck plate having a recess for receiving an article and formed to prevent article rotation in said plate;
a lower puck plate secured to said upper puck plate for rotation therewith;
said plates spaced away from each other.

Abstract
An asymmetric article-carrying puck is driven by a linear star conveyor through an angular rotation orienting section to orient the pucks and articles therein irrespective of random initial orientation. In one embodiment, an upper puck plate carries the article while a separated lower puck plate defines a rotational orienting circular gear rack with a rotation-stopping bridge, separating ends of the rack and inclined from a base of one end tooth in the rack to a crest of another end tooth in the rack. The lower puck plate can be a combination of two circular plates with the circular gear rack interposed therebetween and within the periphery of the circular plates. Pucks can be accumulated in mutual engaged positions and separated by the linear star into preselected pitch while transported and turned. Integral pucks can be used. The structural details and methods are disclosed.

8. An article handling apparatus comprising an article holding circular puck, said puck comprising:
-
an elongated circularly disposed rack comprised of a plurality of teeth and a non-toothed bridge extending between ends of said rack; said bridge having a bridge surface facing radially outwardly and inclined in a radial outward direction from a base of a tooth at one end of said rack toward a crest of another tooth at another end of said rack. - View Dependent Claims (9, 10)

13. A method of orienting, around a vertical axis, an asymmetric article including:
-
capturing said article in an upper plate of a puck; transporting said puck in a downstream direction; engaging recessed puck teeth in a portion of said puck with teeth of an elongated rack disposed in the path of said recessed puck teeth and turning said puck and article; disengaging said recessed puck teeth from said elongated rack teeth and retaining said puck and article in a fixed angular orientation corresponding to said disengagement of said teeth; and thereafter holding said puck and article against further rotation while transporting said puck and articles in a downstream direction. - View Dependent Claims (14, 18)

15. A method of orienting an asymmetric article about an axis and comprising the steps of:
-
carrying an article in a puck having a recessed circular gear of radially extending teeth; engaging said teeth on an elongated orientation rack and turning said puck;
engaging crests of teeth on said rack with a surface of a bridge formed in said gear; andpreventing further rotation of said puck. - View Dependent Claims (16, 17)
