Definitions

  • the invention relates to a device for erecting folding boxes according to the preamble of the main claim.
  • DE-OS 27 20 902 discloses a folding box erecting device with a suction gripper that swings back and forth between a magazine and the conveying device of a cartoning machine, which in each case removes a flat-lying folding box from the magazine and pulls it into the conveying device.
  • a fixed switch presses against an abutting folding edge of the folding box that is being passed, so that it opens and stands up.
  • This very simply designed device works reliably with common folding box formats and an output of up to 250 boxes per minute.
  • the safe opening of the folding boxes is no longer guaranteed if they are relatively flat or high, or consist of a little stiff packaging material. It is therefore desirable to design the known device with which folding boxes with a critical width / depth ratio can be erected and transferred and in which a higher output is possible.
  • a safe opening of the folding boxes is achieved in that the folding boxes removed from the magazine are first transferred in front of a suction cup, which the flat-lying folding boxes by negative pressure on the one Holds the attack side of the erecting suction gripper opposite side until the reciprocating erecting suction gripper has gripped the other side of the respective folding box and opened it by moving it away from the holding suction device.
  • this known device is not very efficient.
  • a slide is in fact arranged, which pushes the bottom folding box lengthwise out of the magazine with drivers. The sliding of the folding boxes on mounting rails and the rubbing on the following one, which remains in the magazine, on the one hand does not allow a high feed rate and on the other hand can leave traces of grinding on high-quality coated folding boxes.
  • the invention has for its object to provide a carton erecting device for high-speed cartoning machines, which ensures the safe opening of the cartons with high output, even if they have critical dimensions and consist of less rigid material.
  • the folding box erecting device according to the invention with the characterizing features of the main claim has the advantage that when the task is solved, its structure is very simple and the effort is very low, since only the transfer device and the feed device require a drive. Since the ends of the arcuate path of the transfer device transversely to the level of the magazine and that of the Hal Te responded run, a gentle removal of the cartons from the magazine is guaranteed and also inevitably a partial opening of the cartons gripped by the holding device by the swinging transfer device possible if the negative pressure is not switched off at the reversal dead center, but only after covering a portion of the arcuate return path.
  • the invention also offers the advantage that the device known from DE-OS 27 20 902 can be upgraded to higher performance and reliability.
  • FIG. 1 shows a known folding box erecting device in a side view
  • FIG. 2 shows a folding box erecting device according to the invention in a side view
  • FIGS. 3 to 6 show the folding box erecting device according to FIG. 2 simplified in different working positions in a side view.
  • FIG 1 The illustrated in Figure 1, by the DE-OS 27 20 902 known Faltschachtelaufrichtvoriques a magazine 12 for receiving a supply of flattened folded boxes 1 above a with drivers 1 3 equipped endless conveyor chain 14 of a cartoning machine.
  • the inclined magazine 12 has at its lower, open end protruding lugs 15, on which the bottom folding box 1 rests.
  • a feed device 16 with at least one suction device 17 is arranged so that it can be swung up and down.
  • the suction device 17 is seated at the free end of an arm 18, through which air is drawn off and which is fastened to the coupling 19 of a four-bar crank mechanism 20.
  • the crank mechanism 20 has a crank 21 and a link 22, both of which are connected to the coupling 19 in an articulated manner.
  • the crank 21 is continuously driven by one revolution in the direction of the arrow 23, so that the suction device 17 runs through a drop-shaped path 24 in the direction of the arrows 25.
  • a fixed switch 26 extends obliquely downward from the front side of the magazine 12 in the conveying direction of the conveyor chain 14 and then runs parallel at a distance from the height of the folding box 1 from the guide rails 27 carrying the folding boxes.
  • the suction device 17 detects the lowermost folding box 1 at its bottom 2 in the area near the folding line 7 to the front side 3 of the folding box 1 by connecting negative pressure via a control valve (not shown).
  • a control valve not shown
  • the folding box 1 Due to the pull exerted by the suction device 17 on the floor 2 and the pressure exerted by the switch 26 on the folding edge 6 between the front side 3 and the upper side 4, the folding box 1 is opened and erected on its way to the conveyor chain 14, where it finally has its rectangular shape obtained between two spread drivers 13 and taken away by them for filling and closing.
  • the folding boxes 1 are erected in a single movement on the way from the magazine 12 to the conveyor chain 14, in the device according to the invention according to FIG. 2 they are first turned from the magazine 1 to a holding device 30 by means of a Transfer device 31 and then transferred from there to the conveyor chain 14 by the known feed device 16. Since the feed device 16 of the device according to FIG. 2 is constructed and operates in the same way as that according to FIG. 1, simplicity is assumed for its parts and for the conveyor chain and its parts used the same reference numerals for the sake of convenience.
  • the holding device 30 is arranged in the region of the top dead center of the suction device 17 of the feed device 16. It has a stationary suction gripper directed obliquely downwards in the form of at least one suction pad 32, which is intermittently connected to a vacuum source via a control valve (not shown).
  • the suction device 32 is fastened to a carrier 33, on which a pusher 34 is also rotatably mounted about an axis lying next to the suction device 32 such that the pusher 34 is limited by a compression spring 35 from the plane of the suction device 32 by a stop 36 Angle in the direction of the feed device 16 is pivotable.
  • the magazine 12 which holds the supply of folding boxes is arranged obliquely next to the holding device 30, its lower output side being in a plane substantially parallel to the holding plane of the holding device 30.
  • the transfer device 31 has a suction gripper in the form of at least one suction device 37, which is directed at the free end of a hollow rod 38 against the underside of the magazine 12 and the holding device 30.
  • a suction gripper in the form of at least one suction device 37, which is directed at the free end of a hollow rod 38 against the underside of the magazine 12 and the holding device 30.
  • the suction device 37 can be connected to a vacuum source.
  • the rod 38 is fixedly connected to the coupling 41 of a four-bar linkage 40 that, in addition to the coupling 41, has a rocker arm 42 and a link 43.
  • the rocker 42 is pivoted in cycles by an angular range of approximately 200 °.
  • the suction device 37 moves back and forth on an arcuate path curve 44 with dead centers on the underside of the magazine 12 and in the holding plane of the suction device 32 of the holding device 30, the end regions of the path curve 44 being essentially perpendicular to the underside of the magazine 12 and to the holding plane of the holding device 30 (FIG. 3).
  • the crank mechanism 20 moves the suction device 17 of the supply device 16 against the holding device 30.
  • the suction device 17 detects the partially opened folding box 1 temporarily held by the suction device 17 of the holding device 30 at the bottom 2 thereof (FIG. 6) and pulls it between a pair of drivers 13 of the continuously running conveyor chain 14, this folding Box 1 is pressed on the folding edge 6 by the switch 26 and erected ( Figures 3 and 4).
  • the holding device 30, which brings the feeding device 31 to a folding box 1 and which engages each other with the suction pads 17 and 37 of the transfer device 31 and the feeding device 16 on the top 4 of the folding box 1 and holds it against partial opening, ensures that the folding boxes are opened securely , even if they are made of less rigid cardboard. Furthermore, the partial opening of the transferred folding box 1 by the returning transfer device 31 increases the performance of the device according to the invention compared to the known one.
  • the position of the magazine can also be steeper or flatter than shown and that it can be easily moved in accordance with the format of the folding boxes. It is essential in another arrangement of the magazine that the end sections of the trajectory of the suction gripper of the transfer device run essentially perpendicular to the magazine end side and to the holding plane of the holding device.
