Abstract
A method and apparatus are provided whereby a generally tubular container is formed on a mandrel with an end member being sealed to the container sidewall to form an open-topped container. The open-topped container is subsequently conveyed through one or more finishing stations for appropriate finishing of the container's open end in order to ready the container for filling and acceptance of a closure. As the open ended container is conveyed incrementally to and received at one or more finishing stations, the bottom of the container is gripped while appropriate modifications are made to the top thereof.
Claims16
Container finishing apparatus comprising:
- at least one receiving station for receiving a supply of open-topped containers;
- conveyor means associated with each said receiving station for incrementally advancing each container received at said associated receiving station in a generally straight path along a container line to at least one subsequent container finishing station;
- container finishing means located at at least one of said subsequent container finishing stations for performing a finishing operation on a container located at said one of said subsequent container finishing stations so as to provide a finished container;
- gripping means operatively related to each said conveyor means for grasping a container at said one of said subsequent container finishing stations and substantially eliminating movement of said thus grasped container at said one of said subsequent container finishing stations, each said gripping means comprising:
- two generally parallel gripping members located respectively at each side of said respective container line, each said gripping member being adapted to mate with the other said gripping member on the opposite side of said respective container line to define jaw means for grasping a container at said one of said subsequent container finishing stations and substantially eliminating movement of said thus grasped container at said one of said subsequent container finishing stations;
- first means operatively related to each said gripping member located at a first side of each container line for moving each gripping member operatively related thereto between a first withdrawn position whereby containers can be moved by said conveyor means operatively related thereto along the generally straight path of the container line adjacent thereto and a second gripping position whereby said jaw means grasps a container;
- and
- second means operatively related to each said gripping member located at a second side of each container line for moving each gripping member operatively related thereto between a first withdrawn position whereby containers can be moved by said conveyor means operatively related thereto along the generally straight path of the container line adjacent thereto and a second gripping position whereby said jaw means grasps a container;
- and
- discharge station means associated with each of said conveyor means for receiving finished containers from said conveyor means and appropriately disposing of said containers thus received.
