  • the invention is a pneumatic container conveyance system for moving containers through processing steps. More particularly, the invention is a pneumatic conveyance system that allows vertical removal of containers from above the container line.
  • Related Art [0002] Many foods, drinks, household products, and other fluids are currently packaged in plastic containers. During container manufacture, as well as subsequent processing, such as storage and retrieval of empty containers, and filling and packaging of containers, efficient systems for conveying containers are required. Retrieval systems interact with conveyance systems to gather, stack and store empty containers for use during operational interruptions and to make up for peak demand or for transferring filled or empty containers to different process stages.
  • One type of existing system for accomplishing these objectives utilizes table top conveyors, on which containers stand, and lane changing devices such as gates and diverters.
  • transition points e.g., gates, diverters and feed points
  • container designs do not run efficiently on table top conveyors due to instability of top heavy, empty containers or the inability of the containers to remain upright at top line speeds. Transferring containers from an air conveyor to table top conveyor requires additional floor space and control equipment, further increasing system complexity.
  • An alternative to a table top conveying system is a pneumatic conveyer.
  • Existing air conveyor designs typically use a plenum and rail arrangement as exemplified in, for example, U.S. Patent No.
  • a plenum is constructed to contain and direct pressurized air.
  • the plenum is located above the rails on which the container is moved.
  • a neck support section and air channeling louvers are mounted to the bottom of the plenum.
  • the neck support section holds the container by the neck flange and the louvers channel pressurized air onto the neck or finish of the container to provide the motive force.
  • Containers move along the length of the neck support rails as a reaction to the motive force of the pressurized air.
  • Such plenum designs may incorporate features such as dump gates and articulating neck guides.
  • a dump gate is an articulating section of neck support rails used to clear line jams.
  • a system will be built that can sense an interruption in container travel, caused by, for example, a stuck or damaged container, and clear itself by articulating the neck support rails open far enough to allow a section of containers to "dump" out, thus clearing the jam.
  • Typical articulation distances are 12 mm to 15 mm.
  • Quick change neck guides use an arrangement in which the neck guides can be opened or closed to change center distance in a precision manner. This can be accomplished in either an automated manner by, for example, an actuator attached to the neck guides, or by manual adjustment of the neck guides. A change in spacing of the neck guides allows containers having different neck sizes to be run on the same piece of equipment.
  • Typical articulation distances are no more than 10 mm to 15 mm.
  • a pneumatic conveyor system that includes a pair of neck guides, one or both of which is moveable, for example by a connected actuator, relative to a container being conveyed.
  • the neck guides include a neck support rail for holding a suspended container as it is being conveyed; and a plenum with a means for diverting the flow of pressurized air out of the plenum, for example a louver, to provide a motive force for conveying the container along the neck support rail.

  • the body plenum can be connected to one or more actuators for horizontal or vertical movement of the body plenum.
  • a method for conveying containers along the conveyance system is also provided. After the container is released by moving the neck guides, it can be transferred to a second conveyor system. Examples of transferring the containers include placing the container on a table top conveyor; moving the container with a robotic arm or gripper; and moving the container with a vacuum cup.
  • the table top conveyor can be part of the base plate.
  • the apparatus also provides methods for removing a container from a conveyance system facilitated by the absence of a plenum above the conveyance system.
  • the container can be removed by moving the neck guides by an amount sufficient to remove the bottle through an opening between the neck guides. Removal can also include raising the base support plate to come in contact with the container in order to support the container when the neck guides are moved.
  • the base support plate can be raised further by an amount sufficient to raise the neck of the container above said neck guides to facilitate removal of the container.
