Patent number: 5507128Abstract: Tandem magazines store tray blanks of different size for loading product in different pack patterns. Each magazine has a depending cam device that engages unique lugs on the tray conveyor to allow the lowermost blank to be received on the tray conveyor, and then to be gripped by the unique lug for transport downstream toward the load station. Since only one magazine is used at one time these cam devices can be deactivated as desired. One of the two blank withdrawing means associated with each magazine is located under the tray blank conveyor and operates in timed relationship with it. The blank withdrawing means are also selectively deactivated for the same reason.Type: GrantFiled: November 10, 1994Date of Patent: April 16, 1996Assignee: Standard-Knapp, Inc.Inventors: Lloyd D.

Patent number: 4551964Abstract: Cardboard packing cases, which have been loaded with bottles or the like, are fed to apparatus for severing the top flap connecting tabs at diagonally opposite corners of the case. These tabs are provided to hold the top flaps of the case in place during loading, but must be severed prior to closing and/or gluing of the top flaps at a succeeding stage in the packing of the product. The apparatus includes an infeed station where the cases are separated, by slowing each case on a flight bar conveyor having its flight spaced less than the length of the case, and then accelerating the case on the infeed conveyor to match the speed of a pocket chain conveyor. The case has its forward end lifted, and opposite corners tilted, on this pocket chain conveyor to spread the top flaps at the two corners of the case without connecting tabs. Guide plates on either side of the pocket chain conveyor serve to guide the case so that fixed knives cut both tabs without necessity for turning the case through 90 degrees.Type: GrantFiled: November 30, 1984Date of Patent: November 12, 1985Assignee: Standard-Knapp, Inc.Inventor: Lloyd D. Johnson

Patent number: 4494355Abstract: A case feeding apparatus moves open cases onto a lift table where each case is moved upwardly onto the funnel portion of a shifting grid structure so that a slug of articles can be deposited therein. Line pressure advances the cases toward a retractable stop and side belts move the cases individually into an intermittently operated pair of case conveyors capable of handling cases of different size. Arrival of a case at the lift table triggers both the raising and lowering of the lift table and an indexing device controls the case conveyor cycle. The cases have their side flaps folded down by side guides to maintain the case in laterally centered positioned on the lift table and each case conveyor has either pusher lugs or leading lugs to control case position longitudinally.Type: GrantFiled: March 19, 1982Date of Patent: January 22, 1985Assignee: Standard-Knapp, Inc.Inventors: Lloyd D. Johnson, Jack H. Lewis

Patent number: 4048783Abstract: Articles are fed in a plurality of lanes from an infeed conveyor, across a deadplate, and into a grid which has lane defining structure adapted to expand and to hold the articles while the grid is inverted. After a charge is formed in the grid, means is provided for holding back articles on the deadplate and for retracting the grid slightly to separate articles in the grid from those on the deadplate. Riding strips, or rails, support the articles in the grid, and latch means provided in part on a vertically reciprocable yoke, and in part on these rails is latched by rotation of the grid and unlatched in response to reset or return motion of the retractable grid. After rotation and retraction of the grid, the articles are released, and the yoke and the rails push the articles out of the grid. The rails and grid are then reset, the unlatched yoke raised, and the holdback releases the articles for loading a succeeding charge without the necessity for return rotational motion of the rails and grid.Type: GrantFiled: November 19, 1976Date of Patent: September 20, 1977Assignee: Emhart Industries, Inc.Inventors: John L.
