  • the first cut pushes, driven by the chain 2, against a broad role 6 and against a small cylinder 7.
  • the roller 6 forms the upper front stop for the first cut and the small one Cylinder 7 forms the lower stop.
  • the role 6 is connected to the frame 1 via an L-shaped lever 8. Of the small cylinder 7 is attached to a tiltable lever element 9, which has a slight deflection of the cylinder 7 in the direction of the arrow 3 forward and downward allowed.
  • the blank removal device 11 Compared to the blank magazine, which in its entirety with 10 is the blank removal device 11 arranged. This has four in particular Suction pads 12, of which only the two in side view front can be seen. These suction pads 12 set in the shown position on the foremost blank.
  • the Suction pads 12, which are not shown in the drawing pneumatic connections connected to a vacuum pump are attached to a head part 13 of the feed device, which has an axis 14 with a shaft 15 is rigidly connected. This shaft 15 is provided laterally in two Rails 16 positively guided. With a backward movement of the suction gripper head 13, the suction grippers 12 are first moved back in the direction of arrow 3 in the lower section of the positive guide 16. The rails 16 move in their central section in a straight line up and go in its end section back into the horizontal.
  • the front flat blank is removed as follows.
  • the suction pads 12 take the foremost blank.
  • the suction cup head 13 tilts the lower lever element 9 with the Cylinder 7 off, so that the front blank in its lower Area becomes vacant.
  • the cylinder 7 goes again back to its starting position.
  • the flat cut always stands with its upper section a few more centimeters, for example up to 20 centimeters or even more, above the roll 6 in the blank magazine.
  • the suction cup head 13 Through the Backward movement and the beginning tilting of the suction cup head 13 also becomes the top section of the foremost blank pulled out of the magazine 10 with its back rubs against the next cut and its front side itself rolls off the roller 6.
  • the choice of the cylinder 7 and the tilt angle should get caught prevent the lower end of the first blank.
  • the provision an upper roll 6 reduces to the first blank attacking forces and simplify its removal.
  • the roller 6 can also be a simple cylindrical or elliptical shaped stop can be provided, which is a light Allows the front blank to slide off.
  • the roll 6 a tilt stop accordingly to provide the lower cylinder 7 and its lever element 9, wherein here the tilting away as just moving away from the stop surface of the foremost blank can be designed. Then after loosening the bottom section of the front one The upper section is then loosened, i.e. of the Contact pressure of the blank magazine taken, so that, too against the stop roller 6, the foremost blank removed can be.
  • FIG. 2 shows the device from FIG. 1 in a front view from the direction of the next workstation, being here only the relevant features are shown. This is here for one the upper roller 6 with the lever 8 by two angles 21 and 22 indicated corner guides for the magazine and here two short cylinders 7 which are part of the tilting device 9 are. All features from Fig. 1 are given the same reference numerals featured.
  • the axis 14 can be clearly seen, to which the four suction cups 12 are attached.
  • the axis 14 is connected via a lever 23 to the short shaft 15, which in the positive guidance 16 slides.
  • With the reference numeral 24 is the Drive designated for the movement of the suction pads 12.
  • This device allows an increased delivery clock rate the cardboard boxes. This requires a safe and quick one Function of magazine 10.
  • FIG. 3 shows the magazine 10 with a pressure device 30.
  • the individual cuts are densely packed vertically in the Magazine 10 and are moved forward using chain 2.
