Definitions

  • the invention relates to a magazine for cardboard blanks or the like with removal suction devices for removing the bottom blank in each case from a stack, this bottom blank resting on its one boundary edge on a transverse leg of an angular stop and providing further support for the edge facing away from it is.
  • the invention has for its object to design a magazine of the type mentioned so that accidental removal of several blanks is avoided.
  • a very advantageous further embodiment of the invention resides in the fact that a pivotably mounted lever is provided which can be pivoted against the bottom blank and at least slightly lifts it up.
  • This lever further loosens the blank stack and also ensures that the airflow from the air nozzle becomes even more effective.
  • a further advantageous embodiment of the invention results if the negative pressure acting on the take-off suction cups is controlled as a function of their speed and switches off earlier at a higher speed.
  • the further support of the bottom blank is designed as a roller bearing.
  • a magazine 1 with a magazine is designated, which is equipped with a number of cardboard blanks 2 and is open both above and below.
  • a take-up suction device 6 pivotably mounted on a lever arm 5, which takes up contact with the bottom carton blank 2 and pulls it out of the stack and places it on a transport chain 7 which passes underneath the magazine.
  • a further lever 8 is pivotally mounted, which is pivotable against the bottom carton blank and slightly raises it.
  • An air nozzle 9 visible in FIG. 2 is incorporated into the angular stop 3 and is connected to an air supply line 10. This air nozzle 9 directs an air flow between the individual cardboard blanks.
  • the take-off suction device 6 and the lever 8 work in the same cycle, but the lever 8 has a slight advance in order to loosen the cardboard blanks before the bottom suction device is gripped by the take-off suction device. At the same time, air flows out of the air nozzle 9 between the blanks that have already been loosened, whereby the loosening is additionally supported.
  • the negative pressure acting on the suction cup (several cut-off cups can also be arranged parallel to one another with correspondingly large cuts) is controlled as a function of the actuation speed of the suction cups and is switched off earlier as the speed increases.
