Abstract
Glass containers are pushed from an infeed conveyor through an arcuate path to a cross conveyor by pushers which have L-shaped fingers which are advanced to an advanced position to engage the containers and which can automatically reorient to maintain the container perfectly centered within the fingers until the container is displaced to a deposit location. The fingers are then pivotally displaced away from the container and subsequently repositioned at the advanced position.
Claims4
A transfer mechanism for transferring containers from an infeed conveyor to a cross conveyor comprising
- a conveyor,
- a plurality of pushers secured to said conveyor for engaging glass containers at a pick-up location on the infeed conveyor and pushing the engaged containers onto the cross conveyor at a deposit location, each of said pushers including
- a finger assembly having L-shaped finger means for engaging a container and having first and second roller means,
- means for mounting said finger assembly for pivotal displacement between advanced and retracted positions,
- guide rail means extending in the direction of motion of said conveyor from a third location proximate said deposit location to a location proximate said pick-up location location for engaging said first roller means and positioning said pusher at said advanced position at said pick-up location, and
- cam groove means extending from a location proximate said deposit location to a location beyond said third location for engaging said second roller and displacing said finger assembly from said advanced position to said retracted position when the engaged container has been displaced to said deposit location.
