Abstract
A method and apparatus for selectively directing work objects wherein the work objects are passed along a path of travel, predetermined characteristics of the work objects are sensed and work objects having the predetermined characteristics are diverted from the path of travel successively to alternate sides of the path of travel without movement in a return direction intermediate diversion of successive work objects.
Claims3
A method for selectively directing work objects, comprising passing said work objects along a primary path of travel;
- individually sensing predetermined characteristics of said work objects;
- and individually selectively diverting said work objects from said primary path of travel at predetermined locations in accordance with said predetermined characteristics of the work objects sensed in said sensing step to alternate sides of said primary path of travel without returning to a start position prior to diverting each successive work object, wherein said diverting includes contacting successive adjacent work objects passing along said primary path of travel, having said predetermined characteristics for diverting at said predetermined locations, in successive swaths of movement in substantially opposite directions across said primary path of travel to divert said successive adjacent work objects to opposite sides of said primary path of travel and wherein said contacting of said successive adjacent work objects is achieved by moving a work object contact member in a first direction to divert a first of said work objects to a first side of said primary path of travel and subsequently by moving said work object contact member in a second direction substantially opposite to said first direction to divert a second of said work objects to a second side of said primary path of travel substantially opposite to said first side of the primary path of travel;
- and collecting said work objects diverted from said path of travel to said first and second sides thereof for delivery to a common destination by establishing substantially continuous secondary paths of travel substantially parallel to and on opposite sides of said primary path of travel disposed individually to receive work objects diverted from said primary path of travel and by establishing a substantially continuous tertiary path of travel beneath said primary path of travel and substantially transversely related thereto in receiving relation to said secondary paths of travel to receive said work objects from the secondary paths of travel for delivery to a common collection point.
An apparatus for selectively directing work objects comprising a conveyor operable to transport a plurality of work objects thereon successively through a work station;
- means for detecting predetermined characteristics of said work objects as they are transported on the conveyor through said work station;
- and means operably connected to said detecting means in said work station operable to divert each work object passing through the work station, having said predetermined characteristics, from the conveyor in a first direction of movement and subsequently to divert the next successive work object so detected in a second direction of movement and wherein said second direction of movement is substantially opposite to the direction of said first direction of movement, said diverting means includes a diverting member mounted above said conveyor for movement in said first and second directions of movement without movement in a return direction after movement in either of said first or second directions of movement and said diverting means further includes a solenoid, mounted above the work object transport conveyor, a drive shaft having a pair of oppositely extending drive end portions and said drive shaft selectively driven in opposite directions and said diverting member is borne by a diverting assembly mounted on the drive shaft of the solenoid and the detecting means is operably connected in actuating relation to said solenoid for movement of the diverting member in said first and second directions of movement.
