Definitions

  • the present invention relates to a forming machine for essentially parallelepiped boxes.
  • a forming machine is a machine adapted to manipulate a cut cardboard box, so as to open said box which at entrance has a closed configuration.
  • a box In closed configuration or prior to forming, a box is essentially flat (flattened) and thus adapted to be transported because the occupied volume is limited.
  • a box In open or formed configuration, a box is three-dimensional or squared, having the surfaces of the box been manipulated so as to identify a central space to be subsequently closed.
  • Said machine further folds the lower flaps so that a subsequent taping machine may seal the lower part of the open box, which thus takes a configuration adapted to accommodate filling material.
  • Forming machines of various type are known, for example those described in US-3608440 , US-3739696 , EP-0260794 and EP-0834395 .
  • a forming machine for essentially parallelepiped boxes, comprising a base frame which supports flattened box collection means, forming means adapted to convert said flattened boxes into parallelepiped boxes provided with lower and upper flaps, flap closing means adapted to close the bottom of the box by folding said lower flaps, characterised in that said forming means comprise a front forming assembly and a rear forming assembly displaceable from a home position to a working position in which they engage the flattened box to respectively square with a synchronised movement a front side and a rear side of the box itself, and further subsequently displaceable again to home position so as to allow the horizontal displacement of the formed box towards an outlet arranged beyond said front forming assembly.
  • a system for preparing essentially parallelepiped boxes 1 to accommodate filling material, the boxes having lower, front 120, rear 121, right side 122 and left side 123, and upper 124 flaps comprises a forming machine 100 which collects flattened boxes 1 from a feeding machine 101, and sends boxes 1 in open or formed (squared) configuration to a taping machine 102 (figure 1).
  • Feeding machine 101 (figures 2-3) comprises a frame 23 which supports a supporting chain 2 of boxes 1 to be formed held in vertical position by adjustable contrasts 3 integral with a pushing carriage 4 mobile along guides 10.

  • Said pushing assembly 4 advances in synchronicity with boxes 1 maintaining them in vertical position by means of ratchets 11 meshing with chain 2, releasable by means of a lever 16, to front supporting springs 12.
  • the feeding machine further comprises box advancement stopping limit stops 13, limit stops 14 indicating the depletion of boxes 1 which activate an indicating lamp 15, and limit stop 17 for stopping the advancement of pushing carriage 4.
  • Adjustment components 103 adapt feeding machine 101 to the different dimensions of box 1.
  • Forming machine 100 comprises a collection carriage 27 which supports mobile withholding suction caps 28, a front forming assembly 200 and a rear forming assembly 201.
  • Rear forming assembly 201 comprises mobile rear forming suction caps 29 supported by a mobile frame 50 by means of rear arm 81.
  • Said withholding suction caps 28 are actuated by a pneumatic cylinder 84 fastened to collection carriage 27 by means of rear fastening 85 (figure 18).
  • Front forming assembly 200 comprises front forming suction caps 37 fastened to a mobile front arm 38 integral with a frame 39 by means of a pin 44.
  • Said front arm 38 is actuated by a pneumatic control assembly 105, comprising pneumatic cylinders 41 and 46, a magnetic sensor 49, and an accelerator/decelerator device 106 (figure 8) described in Italian patent application MI2006A000211 by the same Applicant.
  • Frame 50 supports, by means of crossbar 51, a rear flap closing assembly 52 and an ejector assembly 53.
  • Rear arm 81 on which rear forming suction caps 29 are fastened (figure 10), is connected to an ejector cylinder 82, with magnetic sensor 88, integral with crossbar 51 by means of a support 83 (figure 17).
  • Said frame 50 is rotationally controlled about a pin 55 by means of a pneumatic cylinder 56 (figure 6).
  • Rear flap closing assembly 52 comprises a rear flap closing lever 60 integral with a support 59 by means of a pin 61 and actuated by a pneumatic cylinder 107 (figure 11).
  • the enabling of magnetic sensors 64-66 activates a pneumatic cylinder 67 which is fastened to frame 68 by means of a rear attachment 69 and a supporting plate 70.
  • a roller holder plate 71 which supports front flap closing rollers 72 is fastened on the front side of said pneumatic cylinder 67 (figure 12).
  • a magnetic sensor 73 controls the activation by means of a pneumatic cylinder 77 (figures 14-15), with magnetic sensor 80, of a right longitudinal flap closing lever 74 fastened by means of a pin 75 to a support 76 integral with collection carriage assembly 27.
  • Forming machine 100 further comprises a left side flap closer 92 (figure 6 and 16) and adjustment means which adapt forming machine 100 to the different dimensions of box 1.
  • Taping machine 102 comprises side conveyor belts 89 actuated by a motor assembly 90, and a taping assembly 91 (figure 16).
  • Said taping machine 102 further comprises adjustment means 111 to adapt said machine 102 to the various dimensions of formed box 1.
  • boxes 1 to be formed are supportingly inserted on chain 2 of feeding machine 101 and are induced to advance by means of control assembly 7 which turns splined shaft 8, which advances chain 2 by means of pinion 9.
  • boxes 1 are maintained in vertical position by means of contrasts 3.
  • Said contrasts are integral with pushing carriage 4, guided by dedicated guides 10, which, by means of ratchets 11 meshing with chain 2, advances in synchronicity with boxes 1 maintaining them in vertical position and accompanying them to the front support springs 12.
  • Boxes 1 are made to advance, as described above, until the first box 1 actuates one of the two stopping limit stops 13. Whenever the forming machine collects a box 1, and both limit stops 13 are clear, control assembly 7, which advances boxes 1 until one of the two limit stop 13 is engaged again, is actuated. During use of feeding machine 101, when boxes 1 are reduced in quantity and clear a suitable indicating limit stop 14, an indicating lamp 15 is activated. By means of the rotation of lever 16, ratchet 11 may be released from chain 2 and stop pushing carriage 4 so as to load other boxes 1. If feeding machine 101 is not refilled, at the end of boxes 1, a suitable limit stop 17 will stop the advancement of pushing carriage 4.
  • forming machine 100 is arranged with collection carriage assembly 27 in the position of figure 4, i.e. with mobile withholding suction caps 28 and rear forming suction caps 29 in contact with the first box to be formed 1.
  • the suction caps are actuated by a vacuum system (not shown in the figures).
  • front forming suction caps 37 are made to adhere to front wall 130 of box 1 by rotating frame 39, fastened to collection carriage 27 by means of pin 44 (figure 7).
  • This control is activated by magnetic sensor 45 arranged on pneumatic cylinder 41 and is performed by pneumatic cylinder 46 fastened to collection carriage 27.
  • a suitable magnetic sensor 49 arranged on pneumatic cylinder 46 controls the opening or squaring of box 1 (figure 10).
  • the opening of box 1 occurs by returning front forming suction caps 37 to initial position and by rotating rear forming suction caps 29 by means of rear arm 81.
  • Rear forming suction caps 29 perform the forming step of box 1 by rotating frame 50.
  • rear lower flap 121 of box 1 is further closed by means of rear flap closing assembly 52 (figures 10-11).
  • rear flap closing lever 60 rotates from vertical position to horizontal position by means of pneumatic cylinder 107. With this movement, during the rotation of frame 50, rear flap closing lever 60 folds lower rear flap 121 of box 1 inwards.
  • pneumatic cylinder 67 which moves rollers 72 is activated by means of the enabling of magnetic sensor 64 arranged on front box opening pneumatic cylinder 46, of magnetic sensor 65 arranged on rear box opening pneumatic cylinder 56 and of magnetic sensor 66 arranged on rear flap closing pneumatic cylinder 107.
  • rollers 72 meet front lower flap 120 of box 1, folding it towards the inside thereof.
  • Pneumatic cylinder 67 having reached end of stroke, activates magnetic sensor 73 which controls the activation of right longitudinal flap closing lever 74 and the return to initial position of front flap closing rollers 72.
  • Said lever by means of pneumatic cylinder 77, rotates from home position to horizontal position, as shown in figure 15, folding right side flap 122 of box 1. Simultaneously to the movement of right longitudinal flap closing lever 74, the vacuum to front forming suction caps 37 is deactivated, and mobile front arm 38, onto which said suction caps are fastened, returns to start of cycle position by means of the action of pneumatic cylinder 41.
