Abstract
The invention concerns an apparatus for applying closures to containers. Each closure is carried to a respective container in a chuck of a closure holder mounted on a closure conveyor. The holder has an axially movable spindle which is yieldably moved from a retracted position to an extended position as the closure conveyor moves. The spindle may be selectively rotated while in extended position, by a pulley which is coupled to it by a clutch. The closures are applied to containers moving on a straight run of a container conveyor. The closure conveyor carries the closures along a linear path parallel to the containers while the spindles are sequentially extended to apply the closures.
Claims36
A closure holder for a capper, comprising
- a closure holder support mountable in a closure conveyor,
- a closure holder body mounted to said support,
- said body mounting a spindle having a closure-receiving chuck at one end thereof, said spindle mounted for rotation and axial movement in said body,
- a rotatable pulley for applying rotation to said spindle,
- a cam follower for following a cam,
- means coupling said spindle to said cam follower and yieldably biasing said spindle to follow movement of said cam follower to extend said spindle, and
- means for moving said spindle toward a retracted position, movement of said cam follower from a starting position yieldably moving said spindle to an extended position, said spindle being rotatable as it is moving toward said extended position.
Apparatus for applying closures to containers, comprising,
- a conveyor for moving containers in a row along a straight line path of movement,
- an endless closure conveyor in the form of a loop, said closure conveyor mounting closure holders for movement along a run parallel to said path,
- each closure holder receiving a closure from a source and, while on said run, applying said closure onto a container while said container is moving along said path, each said holder comprising,
- a chuck for telescoping around a closure at said source, said chuck being axially movable between extended and retracted positions,
- means for extending said chuck from said retracted position to apply said closure onto a container, said chuck extending means being spring biased so that said chuck is extended resiliently.
