Definitions

  • the invention relates to a device for suctioning and applying a blank from cardboard or the like.
  • the suction cups With a plurality of suction cups and a rotating and transport device for the suction cups and the cuts, the suction cups being fastened to a shaft which can be rotated with its two end sections an eccentric drive or a corresponding eccentric bearing is mounted, both of which are rotatably seated on a lever arm pair, both arms of the lever arm pair being fixedly mounted on a likewise rotatable and driven shaft, on which a wheel is also mounted via a ball bearing, which stands still and is connected to the eccentric drive via a gear ratio.
  • the suction cups are attached to pivotally mounted lever arms, only participate in their pivoting movement between 60 ° and 90 ° and are able to deposit a cardboard blank from a stack onto a station immediately below.
  • the suction cups grip the blanks from below, remain on their underside and require space at the storage station in order to be able to deposit the blank.
  • Such a device is known from FR-A-2 487 310, which takes up a lot of space due to its gear device.
  • the invention has for its object to provide a device of the type mentioned, with which even relatively large blanks can be manipulated without the need to create space in the storage station for the suction cups and their carriers.
  • the device designed in this way can suck off blanks at any point on a circular path and likewise place the blank at any point on this circular path from the inside without thereby requiring a great deal of space for the moving device or for manipulating the blanks.
  • FIG. 1 denotes a device which has three pairs of lever arms 2, of which only three lever arms 4, 5, 6 combined on a common carrier 3 can be seen.
  • Each lever arm 4, 5 or 6 carries an eccentric drive 7 which is connected to a plurality of suction cups 9 via a shaft 8.
  • the carrier 3 sits firmly on a further rotatably mounted shaft 10, which in turn is driven.
  • FIG. 3 the device 11 is shown in FIG. 2 in longitudinal section, the attachment of the suction cups 9 to the shaft 8 is visible, which has a U-shaped course.
  • One angled end of the shaft 8 is supported on the eccentric drive 7, while the other angled end is supported on an eccentric bearing 17.
  • These eccentric bearings 17 are in turn rotatably attached to lever arms 14 and 15 of a carrier 23.
  • the eccentric bearing 7 is connected via a pin 18 to a gear 19, which in turn is connected via a toothed belt 20 to a further gear 21 which sits on the shaft 10 via a ball bearing and does not rotate with it.
  • a further gear wheel 24 is arranged around the pin 18 and has no connection with the pin, but is rigidly connected to the lever arm 4 or 5.
  • This gearwheel 24 is connected via a toothed belt 25 to a gearwheel 26 which is seated on the bearing journal 27 of the one end of the U-shaped shaft 8.
  • Corresponding pins 28 and bearing pins 37 are provided in the lever arms 14 and 15, respectively.
  • the suction devices 9 are connected via lines 29 and 30 to a vacuum pump, not shown, and are supplied by this with the vacuum required for suctioning blanks 31.
  • the entire device is rotated via the shaft 10 into the position required in each case, in which either a blank is to be suctioned off or applied. Simultaneously with this rotary movement, the suction cups 9 perform a lifting movement which extends between the two end positions A and B.
  • the movement of the blank 31 held by the suckers 9 during the rotational movement of the device indicated by the arrow P is shown in the two exemplary embodiments according to FIGS. 1 and 2.
  • the blank is always within the boundary lines of the entire device, the suction cups 9 always pointing outwards.
  • the blanks are also always within the limits of the device, but during the rotational movement the suction cups are turned inwards, so that the blanks are still further inside the device.
  • the size of the individual gears and thus the gear ratio present is adapted to the given requirements.
