Packaging & Automation    |   home      back to     Carton Magazine Loader   Principal Features Langenpac has developed a highly reliable Automatic Carton Magazine Loader designed for high speed packaging applications that would require constant operator attention to maintain the stock of cartons in the carton magazine infeed. In these high speed environments, blank cartons (as well as product) must be continuously fed into the cartoner in order to maintain productivity levels; failure to feed cartons in time will stop production. The Langenpac Automatic Carton Magazine Loader provides a carton buffer that is able to continuously feed blank cartons into the carton magazine infeed without the need for constant operator attention. By automatically loading carton blanks into the cartoner, the Automatic Carton Magazine Loader is able to reduce the number of machine operators, allow existing operators to perform more skilled tasks, as well as reduce the physical strain of lifting carton boxes. The optional Automatic Carton Magazine Loader is recommended for higher speed cartoners such as our Chinook horizontal cartoners, and/or when carton thickness exceeds a point where manually loading cartons becomes difficult to handle or unsafe. Performance Parameters The carton blanks, supplied in trays, are placed on 2 roller conveyors which are at two different heights. The heights of the both roller conveyors is about 750 and 1100 mm. Trays are placed upright on the roller conveyors. These two conveyors act as a buffer and can accumulate and stock multiple trays of carton blanks. A lifting device will receive the trays from both levels. The lifting movement is driven by two linear units. During lifting, a rotation unit performs a 180º rotation, thereby flipping the trays over, and onto a transfer unit. A servo-enabled transfer unit moves the trays towards the extended conveyor of the carton magazine and into the carton feeder. Empty trays are automatically discharged. Each tray could store approximately 250 blanks, based on a blank thickness of 3 mm and a tray length of approx. 750 mm. Depending on the average speed of the cartoner and size of the cartons, operators typically have 30 minutes before they will need to reload the trays of carton blanks.
