Definitions

  • the invention relates to a device for removing, erecting and transferring folding box sleeves according to the preamble of the main claim.
  • a device of this type is already known from US Pat. No. 4,211,153, but in which the rotor rotates about a fixed axis.
  • the suction cups are fastened to radially movable supports which are guided in the links of the rotor.
  • a complicated mechanism with a pawl controls a relative movement between the rotor and carriers during each rotation step of the rotor, so that these are adjusted radially.
  • the inventive device for removing, erecting and transferring folding box sleeves with the characterizing features of the main claim has the advantages that its construction is relatively simple and that a very high output can be achieved with it.
  • the magazine can be arranged in front of the conveyor for the erected folding boxes, so that the conveyor track of the conveyor is freely accessible from above.
  • FIG. 1 shows a device for removing, erecting and transferring folding box sleeves in a side view in a first position
  • FIG. 2 shows the device according to FIG. 1 in a side view in a second position.
  • a cartoning machine not shown, has a conveyor chain 10 with driver pairs 11, 12 which feed folding boxes 1 to various processing stations in a horizontal conveyor track.
  • the step-by-step conveyor chain 10 runs via a deflection section into the horizontal conveyor track, at the beginning of which a transfer station 13 for the folding boxes is arranged.
  • the device for removing, erecting and transferring the folding boxes 1 is arranged between the removal end 16 and the transfer station 13. It has a rotor 20 with three suction cups 21, 22, 23 which protrude radially at equal angular intervals and which is gradually rotated clockwise by 120 °.
  • the rotor 20 is rotatably mounted on a pivotable arm 24, the pivot axis 25 of which is located below the removal end 16 of the magazine 15.
  • the swivel arm 24 is connected to a crank 27 by a coupling 26. When the crank 27 rotates, the rotor 20 is pivoted back and forth on an arc between the removal end 16 of the magazine 15 and the transfer station 13.
  • the rotor 20 is rotated clockwise by 120 ° in each case via two belt drives, one of which has a driving wheel 31 on a gear 30, a driven wheel 32 on the pivot axis 25 and a toothed belt 33 and the other one with the driven wheel 32 connected driving wheel 34, a driven wheel 35 connected to the rotor 20 and a toothed belt 36.
  • the gear 30, which is driven by the packaging machine via a toothed belt drive 38, sets the crank 27 in uniform circulation, so that the crank 27 executes one revolution per cycle of the conveyor chain 10. It drives the rotor 20 step by step, so that its pause in rotation essentially coincides with the pivoting movement of the rotor 20 away from the removal end 16 of the magazine 15 towards the transfer station 13. Due to these drives, the suction cups 21, 22, 23 move on a self-contained path, which is composed of several sheets, as shown in broken lines in FIG.
  • the suction device 21 moves from a point 41 during the pause in rotation of the rotor 20 by pivoting the arm 24 from top dead center to bottom dead center on a circular arc to a point 42, wherein he has a folding box 1 from the magazine 15 takes. While the arm 24 swings back again from the bottom dead center to the top dead center, the pivoting movement of the rotor 20 is superimposed on a rotary movement by 120 °, so that the suction device 21 moves from point 42 on an arc to a point 43.
  • the second suction device 22 moves from point 43 to a point 44 and from there likewise on an arc to a point 45 in the area of the transfer station 13.
  • the third suction device 23 moves on an arc to a lower one Point 46 and from there on a relatively flat long arc back to point 41 on the magazine 15.
  • the arc shape of the path of the suction cups 21, 22, 23 from one of the points 41 to 46 is further influenced by the fact that when the arm 24 is pivoted one of the Drive generated by the gear 30 superimposed rotary motion.
  • the suction device 21 detects the foremost flat-lying folding box 1 in the magazine 15 in the region of the point 41 and pulls it away from the removal end 16 of the magazine, the upper edge thereof against a stop surface 50 strikes and something is retained on it so that the folding box 1 partially opens ( Figure 2).
  • this folding box 1 is then brought to a point in which the suction device 21 is located at point 43.
  • the folding box 1 previously removed from the magazine 15 by the suction device 22 becomes during the pivoting movement of the arm 24 from point 43 to point 44 and from there during the rotary movement of the rotor 20 and the return stroke of the arm 24 into the transfer station 13 to point 45 brought.
  • a counter suction device 52 moves on a lever 53 against the wall 7 of the folding box 1, which is opposite the wall 6, on which the suction device 22 engages.
  • the detected folding box 1 is opened and broken so that the tensions in the edges are released so far that the folding box 1 assumes a rectangular cross section.
  • This erection and counter-breaking of the folding boxes 1 can support a fixed stop switch 54 in the conveying path of the folding box 1 or even carry it out automatically.
  • a head flap 2 protruding from the folding box 1 is bent upwards by a fixed switch 55.
  • the folding box 1 strikes with its front wall 8 in the conveying direction against a stop plate 56, so that it essentially maintains its rectangular cross section.
  • the sucker 23 presses the folding box 1 on an arc between points 45 and 46 obliquely downward between two drivers 11, 12 of the conveyor chain 10 during the oscillating movement of the arm 24 from the upper position to the lower position
  • Movement of the suction device 23 with a folding box 1 for inserting the folding box between two drivers 11, 12 of the conveying device 10 comprises a vertical and a horizontal component.
  • the horizontal component corresponds to the horizontal inlet movement of the drivers 11, 12, the conveyor chain 10 when it enters the transfer station 13, so that the side walls 8, 9 of the folding boxes 1 are inserted smoothly between the drivers 11, 12 which are partially spread out when they enter the transfer station 13 .
  • the transfer station 13 is also assigned two vertical fingers 57, 58, which bend projecting side tabs 3, 4 on the side walls of the fat chutes) 1 (FIG. 2). Shortly before the arm 24 reaches its lower dead position, the vacuum on the suction device 23 is switched off, so that the folding box 1 inserted between the drivers 11, 12 is released by the suction device 23. Then the suction device 23 returns from the point 46 during a rotating step of the rotor 20 and the return movement of the arm 24 to the point 41 at the removal end 16 of the magazine 15. In this way, the removal, the erection and the transfer of folding boxes 1 are repeated with each work cycle of the device and the conveyor of the cartoning machine.
  • the rotor 20 rotates in the area of the transfer station 13 counter to the conveying direction of the conveying device 10, it is possible to arrange the magazine 15 in front of the conveying device 10 so that it does not cover the conveying device 10.
  • the folding boxes 1 introduced in the transfer station 13 between two drivers 11, 12 of the conveyor chain 10 rest with their lower wall 7 on horizontal rails 60 and slide on them during the conveyance by the drivers 11, 12.
  • a horizontal switch 59 is arranged at the level of the rails 60, which bends the securing tab 5 downward.
  • the control of the vacuum for the suction cups 21, 22, 23 is carried out by a rotary slide valve, known per se, not shown, arranged coaxially with the rotor 20, in such a way that the respective suction cups 21, 22, 23 a negative pressure is switched on and maintained until the relevant folding box 1 is inserted on the transfer station 13 between two drivers 11, 12.
  • suction units In addition to three suction units, only two or more than three can be arranged on the rotor 20, in which case the respective angle of rotation of the rotor 20 is adapted accordingly.
  • the arrangement of more than two suction units has the advantage that there are one or more intermediate stations at which devices for treating the folding boxes, such as breaking or edging, forced opening, marking, gluing, etc. can be arranged.
