Definitions

  • the subject of the present invention is a device for correcting rollers or strip for lateral alignment, during shaping, of articles in sheets or sheets partially folded in a folder-gluer; machine commonly used in the packaging industry for making, for example, cardboard boxes from plate elements cut out.
  • such machines generally consist at least of a feeder feeding the production of the boxes cut by cut from of a pile, of a breaker pre-crushing the 1st and 3rd folds at 180o then opening to again the cutting, of a module of folding machines with hooks which fold 180o the front legs then the rear legs of the cutout, of a gluing station, a folding machine with propellers and conical rollers for folding the 2nd and 4th folds of the cutting, of a presser which compresses the 2nd and 4th folds and deposits the boxes in tablecloth, and finally a receiving module which receives the boxes while now pressed to allow the glue to dry.
  • the conveying of the cuts from one station to another is done at using belt conveyors which, by friction, grab the cut either between lower and upper belts, i.e. between belts lower and upper support rollers. It is common for such lower and upper conveyor devices are associated with means to orient the articles in a determined position at the entrance of the production line. In the case of folder-gluers, it is indeed each of the cutouts must be perfectly aligned according to one of its lateral sides in an orientation parallel to the direction of its conveying before undertaking any folding operation.
  • this alignment lateral is made at the entrance of the machine, generally by the feeder which introduces the cutouts one by one on the belt conveyors in a position already perfectly aligned laterally, no device ensuring specifically this alignment is only planned along the path of the cutting in modules or stations located downstream of the feeder, where the scrolling items have already been partially shaped by the folder-gluer.
  • the reason for this state is that in a production process such as previously described, the cut, once properly aligned, can be transformed into a box state without the folding or gluing operations disrupt its lateral alignment.
  • the Swiss patent application No 1997 1274/97 proposes a roller conveyor device modifying the manufacturing method by pivoting, one by one in the horizontal plane scrolling elements of low specific mass.
  • this invention once the front legs of the cutout were folded by the front hooks, it just repeat the same operation for the rear front legs after having took care to rotate the cutout on itself by half a turn in a horizontal plane.
  • This alternative meets a double criterion aimed at improving production, on the one hand by halving the number of passages necessary for the realization of certain boxes with complicated folding, and on the other hand, by endeavoring to reduce the costs of manufacture of such machines.
  • the present invention provides a corrective device for restoring alignment initial side of any article in sheet or plate partially folded and / or glued, having undergone a pivoting in the horizontal plane during shaping in a folder-gluer.
  • the present invention relates to a corrector to rollers or strip of the aforementioned type and in accordance with what the claim 1.
  • the use of a single lower conveyor in combination with an intangible support capable of pressing the cutout on the lower conveyor only allows get rid of any mechanical constraint within the cut between its different parts.
  • the immaterial support means in question is given by a source creating depression or overpressure atmospheric, respectively below or above the scrolling article on the lower conveyor only.
  • this new device corrector also guarantees, thanks to independent training of its lower carrier, maintaining a transition zone in which cuts can be decelerated to reduce the distance separating them. Indeed, given the rarely circular geometry of the cutouts shaped, it is necessary that the spacing between them has been more important in the area of their pivoting, within the previous module, that everywhere else in the production line. However, in order to optimize the subsequent rate of production of the boxes, it is of course advantageous to be able to find the initial spacing of the cutouts as it was before their introduction into the swivel module.
  • the corrective device according to the invention also ensures that action by independent adjustment of his training speed. The scrolling articles will thus be able to undergo a deceleration during lateral realignment, without fear of any damage of their previously folded parts.
  • Figure 1 provides a general view of the correction device 1 mounted between frames 2 (C.C.) and 3 (C.O.C.) of the folder-gluer, downstream of a pivot module 4 for turning the articles 8 in the plane horizontal in accordance with the new manufacturing method mentioned above.
  • the direction of movement of the articles 8 scrolling above each of these devices 1 and 4 is given by the direction indicated by the arrow 5, and the axis 9 defined the initial virtual line against which said articles 8 fell previously supported in their upstream path before their rotation in the conveyor device 4.
  • the device corrector 1 is based on a lower structure 6 transversely sliding, consisting of two rectangular cheeks 10 and 11, arranged vertically in their length on either side of the longitudinal axis 7 of the corrector 1.
  • two crosspieces 12 and 13 are screwed, by their ends, to the cheeks 10 and 11 by pairs of screw 14.
  • the along these, two longitudinal crosspieces 15 and 16 screwed by a plurality of screws 17 against the interior blanks of these cheeks.
  • the upper part 26 of the device 1 mobile part in rotation in a horizontal plane around a pivot point 30.
  • the structure forming the base of that upper part consists mainly of two side members 31 and 32 respectively placed on the driver side and on the side opposite driver. These beams are separated upstream by a plate 33 arranged horizontally and screwed into each of them by pairs of screw 34, and downstream by a spacer 35 screwed at its ends by screws 36 and crossed in its middle part by the pivot point 30.
  • the pivoting mechanism is actuated by the rotation of a steering wheel 46 disposed on the driver side upstream of the corrector device 1 on the upper part 26 ( Figure 2).
  • This flywheel is pinned on a through screw 47 first of all a stop ring 48 arranged in the spar 31, then a stud threaded 49 constituting a support element which cannot deviate transversely of axis 7.
  • this stud comprises at its base a axis 50 passing first through the plate 33 secured to the pivoting part upper 26, then the plate 41 rigidly fixed to the sliding part lower 6 ( Figure 4).
  • the latter is pierced with a comfortable rectangular opening 51 of length equal to the maximum stroke which the upper part 26 can pivot the lower part 6 ( Figure 2). So that the screw 47 can induce movement of rotation of the upper part 26 while remaining integral with the latter, it is necessary that the threaded stud 49 can, through its axis 50, to both turn on itself and move across the plate 41 in a longitudinal movement along the axis 7 of the correction device. To do this, the axis 50 is held in its vertical plane by a circlip 52 while being able to move longitudinally through an oblong opening 53 formed in the plate 41 along the axis 7.
  • Locking the upper part 26 in an oblique position axis 55 is illustrated in Figure 5 and obtained by tightening two brackets 60 and 61 between them, one secured to the upper part and the other to the part of the corrective device.
  • the upper bracket 60 is screwed into the spar 31 by two screws 62, and the lower bracket 61 is made secured to the cheek 10 by two screws 63.
  • the conveying of the scrolling articles 8 is ensured by a plurality of rollers 70 aligned side by side and resting at their ends in ball bearings 71 and 72 housed in the upper part of the side members 31 and 32.
  • a screw 73 makes it possible to fix the corresponding span of the roller 70 in the bore of the bearing 71 as shown in Figure 4.
  • each bearing 72 is held axially from each of its sides by a stop plate 74 screwed to the side member 32 by a plurality of screws 75.
  • a screw 76 maintains a pulley 77 on the bearing surface each roller 70.
  • Two bent protective sheets 78 and 79 are fixed on along each spar 31 and 32 and constitute a security guard against the exposed side portions of the rollers.
  • Figure 3 makes it possible to follow, in phantom, the winding course a belt 80 running around the pulleys 77, and around a plurality of return pulleys 82. Each of these is fixed to the side member 32, opposite driver side, by a screw 83 passing through its ball bearing 84.
  • the entire roller drive device 70 is located on the side opposite conductor outside the cheek 11 and the side member 32.
  • the belt 80 is set in motion by the rotation of a drive pulley 85 of large diameter, mounted on at least one ball bearing 86 itself crossed by a hexagon drive axle 87. The latter is maintained in its ends by ball bearings, housed against the frames 2 and 3 of the folder-gluer, and driven in its C.O.C.
  • an extendable protection 90 fixed against the faces interior of frames 2 and 3, covers the drive axis 87 in both areas outside the cheeks 10 and 11.
  • a second protection 91 consisting of a trapezoidal sheet held against the cheek 11 by spacers 92, completely hides the belt drive 80 and This prevents any dangerous access to the moving part ( Figures 1 and 5).
  • the belt 80 passes through a tension pulley 93 adjustable in position in the horizontal plane using an adjustment screw 94. This tensioning pulley can freely slide along the beam 32 in a groove 95 to bear, by tensioning the belt, against the screw setting 94.
  • the latter is supported by a tapped stud 96 fixed by two screws against the outer face of the beam 32.
  • FIGS. 1 and 4 show a longitudinal guide rail 100, welded against the lateral edges of two metal tabs 101 each pierced with a oblong opening 102 which precisely allows this rail to be positioned different distances from the frame 2, in an orientation parallel to the axis 7 of the folder-gluer.
  • the inner edge of this rail should merge with axis 9 materializing the virtual line against which the line must be aligned corresponding edge of each of the articles leaving the correcting device.
  • Two knobs 103 ensure the tightening of the guide rail after have it positioned correctly by means of two strips graduated by example.
  • Each of the knobs 103 is screwed, on the driver's side or the other, in a support 104 fixed on a spacer 105 by two screws 106.
  • the spacer 105 is fixed by two screws 107 on the crosspiece 15 or 16 respectively through the cheek 10 or 11.
  • a fan 110 centered on axis 55, is placed just below the rollers 70 so as to create a tacky suction source the scrolling elements 8 against the upper surface of the rollers.
  • suction source 110 is fixed under a perforated sheet 111, bent upward at its ends, and occupying all the available space between the beams 31 and 32.
  • Brackets 112 and fixing screws 113 hold the perforated sheet against the faces interior of the side members 31 and 32.
  • a second sheet 114 perforated and retractable, is placed above the scrolling articles on the rollers 70, and makes it possible to avoid the natural raising of their parts previously folded.
