Definitions

  • the present invention relates to a machine for forming boxes, of the type now known as a "quadrangular" machine, in particular for producing packing boxes from paper or cardboard blanks.
  • Prior art box production devices substantially consist of machines which fold a blank to form the lateral walls of a box and of sealing heads which seal together the corners formed between the initially open lateral walls of the box.
  • the box corners are usually sealed by sealing heads with "V"-shaped pressers extending parallel with the lateral walls of the box. Said pressers are fed along the bisecting lines of the base of the box until they make contact with the end portions of the lateral walls, so that they are placed over the corner of the box.
  • the sealing heads then apply heat-sealing strips or tapes to the corners in contact and, by means of the pressers, join said strips to the corners, making the lateral walls of the box integral with one another.
  • GB 325741 describes a quadrangular machine in which the opposite sealing heads can be rotated about a shared axis, so that it is easy to change the size, that is to say, vary the dimensions of the box, and/or pass from a square shape to a rectangular shape and vice versa.
  • EP 1609585 describes a machine with sealing heads able to oscillate relative to an axis in order to vary the approach direction.
  • the sealing heads are mounted in pairs on opposite parallel sliding cross-members, angled according to a first direction and able to move relative to one another in a perpendicular direction.
  • US 2641973 describes a machine with sealing heads arranged in pairs, in such a way that each pair of heads can be slided in perpendicular directions.
  • the sealing heads are adjusted by moving the cross-members and therefore the sealing heads along the cross-members to position the pressers at the corners of the boxes, then making the heads oscillate until the desired approach angle is found.
  • the technical purpose of the present invention is to propose a quadrangular machine which is free of the above-mentioned disadvantages.
  • the present invention has for an aim to provide a machine for producing boxes which allows the production of boxes with any plan extension and preferably boxes with more than four sides.
  • the machine 1 comprises a base frame 2 and at least one turret 3, but usually a plurality of turrets, associated with the frame 2.
  • Each turret 3 comprises a sealing head 4, or presser, designed to stably join the corners of a box being formed by applying a heat-sealed or glued material tape to the corner.
  • Each sealing head 4 preferably has an angular profile with an amplitude that differs according to the angle of the corner formed by the lateral walls of the box.
  • the head 4 opening will be 90°, whilst for boxes with a regular hexagonal plan the opening will be 120°.
  • the sealing heads 4 may be removably associated with the turret 3, so that, depending on the angle formed by the corner of the box to be formed, the most suitable sealing heads 4 can be mounted on the turrets 3.
  • the machine 1 also comprises means 5 for feeding a blank (schematically illustrated in Figure 2 ) acting on the base frame 2 to feed a blank to a start of forming table 30 in a position between the sealing heads 4.
  • a blank (schematically illustrated in Figure 2 ) acting on the base frame 2 to feed a blank to a start of forming table 30 in a position between the sealing heads 4.
  • blank in the context of this invention, refers to a sheet of paper or plastic material 31 comprising a plurality of pre-creasing lines 32 along which the blank is folded to create the box being formed.
  • the means 5 preferably comprise a stepping elevator 50 with a pick up mechanism (of the known type) which picks up blanks 31 one after another from the elevator 50 and feeds them to a conveyor belt 51 which in turn places the blanks on the table 30.
  • a pick up mechanism of the known type
  • the machine also comprises a counter-mould 10 having the same shape and size as the base wall 34 of the box to be produced and vertically movable driven by an actuator 33.
  • the counter-mould 10 performs a downstroke until it is positioned over a base section 34 of the blank on the table 30, and drags down the blank until it is positioned on a box forming table 6 below the table 30 and around which the various turrets 3 are located.
  • the blanks are folded by the combined action of the counter-mould 10 and folder elements 7, schematically illustrated in Figure 4 , positioned at and outside the sides of the base section of the box so as to intercept the downstroke of the sides 35 and fold them against the mould 10.
  • the box closing or sealing step begins, carried out in the known way as the turret 3 sealing heads 4 place strips 52 of heat-sealed or glued material along the open corners 49.
  • the machine 1 also comprises a turret holder unit 13 associated with each turret 3 and comprising a "cross carriage” type mechanism consisting of two slides 38, 39 which can slide relative to one another.
  • Each turret holder unit 13 can therefore slide in an adjustable way along two directions B, C perpendicular to one another (respectively horizontal/vertical with reference to Figure 5a ) relative to the base frame 2 and the position of the mould 10, so that they adapt to the dimensions of the box to be formed and to the positions occupied by the vertices of the corners 49 of the box to be sealed.
  • each turret holder unit 13 is mounted on a cross-member 53 moved by screws 75 and in a direction C along guides 54 fixed on the frame 2.
  • each unit 13 slides in the direction C together with the respective cross-member 53 (first controlled movement), and can also be moved independently in directions B, C (second controlled movement) relative to the position of the cross-member 53, thanks to the slides 38, 39.
  • first guide means 14 for example worm screws angled in the direction B and acting on the slide 38 and associated with the cross-member 53 so that the first slide 38 can slide in an adjustable way on linear prismatic guides located on the cross-member 53.
  • said means consist of a movable adjusting screw 14' integral with the screw 14 and engaging in a bushing 77 integral with the slide 38 (movement B).
  • the movement in direction C is adjusted by second guide means 15, for example a worm screw angled in the direction C, associated with the slide 38 and engaging with the slide 39 in such a way that the second slide 39 can slide in an adjustable way on linear prismatic guides 40 located on the slide 38, for movement of the slides 38 and 39 relative to one another in direction C.
  • second guide means for example a worm screw angled in the direction C, associated with the slide 38 and engaging with the slide 39 in such a way that the second slide 39 can slide in an adjustable way on linear prismatic guides 40 located on the slide 38, for movement of the slides 38 and 39 relative to one another in direction C.
  • the rotation of the screws 14, 15, 75 and the movement of the cross-members 53 can be adjusted and controlled automatically or manually with each size change-over for the boxes being produced, depending on the selected machine operating mode.
  • each unit 13 is therefore capable of two movements in direction B, one approach movement controlled by the screw 14 and one adjusting movement controlled by the screw 14', and two movements in direction C, one approach movement controlled by movement of the cross-members 53 and one additional adjusting movement controlled by the screw 15.
  • a turret 3 is rotatably connected on the unit 13 relative to the position of the counter-mould 10 and therefore of the box 36, so that it can define a plurality of directions A1 - An for the sealing head 4 to approach the box being formed, as is schematically illustrated in Figure 3 .
  • the turrets 3 have pins 41 which engage with circular slots 42 made in the upper surface of the slide 39 and positioned in a circle preferably with a centre R coinciding with the vertex of the sealing head 4 profile.
  • each rotary turret may be adjusted and angled according to one of the approach directions A, guaranteeing that the machine 1 can produce boxes with corners having different amplitudes and orientation, depending on the shape of the box base wall.
  • the sealing head 4 may also be able to slide relative to the turret 3 along each approach direction A to perform the operating stroke.
  • each turret 3 comprises an actuator cylinder 12 on which the sealing head 4 is removably connected.
  • Said actuator 12 therefore allows the sealing head 4 to slide along the approach direction relative to which the turret 3 is angled, to guarantee that the sealing head 4 makes contact with the corner to be sealed, applying the necessary pressure on the heat-sealing tape.
  • Each turret 3 also comprises means 18 for feeding sealing tapes to each sealing head 4.
  • the feed means 18 are of the known type consisting for example of wheels 60 positioned on each turret 3 and continuously feeding a measured length of sealing tape 43 between the sealing head 4 and the corner of the box to be sealed in combination with a pressure wheel 61.
  • each sealing head may have independent feed means, allowing them to feed different lengths of sealing tape for corners of different heights on the same box.
  • said tape is applied by heat-sealing the tape on the corner of the box by heating the sealing head 4.
  • a tape comprising a surface on which there is a layer of adhesive material which is activated by the heat produced by the sealing head 4.
  • the machine 1 also comprises means 20 for extracting the formed box, that is to say the box with the sealed corners, acting on the box to move it away from the forming table 6.
  • the extracting means 20 comprise an extractor element which intercepts the box to move it away from the forming table 6.
  • the element 20 advantageously comprises a suction cup 21 at one end of a rod 22 guided by vertical guides 47 and moved vertically by a drive unit 46.
  • the box being formed has its base 36 on the operating table 6, and the open corners 49 positioned at a distance from the centre O of the base 36 equal to a generic value b, c, respectively in directions B and C.
  • FIGS 5a and 5b show this step from above.
  • this movement occurs with an approach motion consisting of a first movement of the cross-members 53 in direction C, then independent adjustment in directions C, B of each turret 3 by the adjusting means 14, 40 acting on the slides 38, 39.
  • Figure 5b shows the advantage gained from independent adjustment of all of the units 13, allowing sealing of boxes with any irregular plan (for example without axes of symmetry), in which the amplitude of the coordinates (b, c) of the corners 49 to be sealed may be significantly different from one another, both for quadrangular and generically polygonal boxes.
  • the head 4 actuators 12 can perform the operating stroke in direction A and seal the open corners with the heat-sealing tapes.
  • the angular orientation of the heads 4 is given not by an adjustment, but by the preset position of one or more heads, angled without the possibility of oscillating so as to make the direction A of the operating stroke coincide with the best bisecting line of the corner 49 for sealing a predetermined corner of the box.
  • a set of one or more heads 4 may be installed, set up to have operating directions with different angles and corresponding to the geometry of the box to be formed.
  • the suction cup 21 makes contact with the base wall of the box 36 and stably connects with it to allow the formed box to be moved from the forming table 6 to an extraction table 45, so that another blank 31 can be fed and a new box formed.
  • Each blank 31 consists of a single body comprising a polygonal base 34 and a number of individual walls 35/35' overall equal to the number of sides of the base 34.
  • each wall 35 of the blank 31 is joined to the base 34 by a fold line 32 in such a way that once the blank has been folded in the quadrangular machine, the sealing heads can seal the four open corners 49 to obtain a box closed at all its corners, on the base and lateral.
  • the blanks of the invention illustrated by way of example in Figures 7a - 7c , have at least one side 55 of the base 34 free, and at least one wall 35' joined both to the base 34 by a first fold line 32 and to at least a second wall 35 by a second fold line 56 converging with and at a right angle to the line 32, so as to constitute at least one multiple part 57.
  • the blank 31 has a pentagonal base 34 joined by two fold lines 32 to two multiple walls 57 consisting respectively of two and three adjacent walls 35/35'.
  • the blank has a hexagonal base 34, joined by two fold lines 32 to two symmetrically opposite multiple walls 57, both consisting of three adjacent walls 35/35'.
  • the blank has an octagonal base 34, joined by two fold lines 32 to two multiple walls 57 joined to two opposite sides of the base 34 and each consisting of three adjacent walls 35/35'.
  • the blank is completed by two single walls 35 joined to the opposite sides of the base 34 at right angles to the sides joined to the multiple walls.
  • the number of multiple walls 57 is determined in such a way that folding the blank 31 on the counter-mould 10 results in the formation of a box with a number of open corners 49 less than or equal to four and therefore suitable for sealing in a quadrangular machine.
  • the independence of the sealing head movements makes it easy for the sealing heads to approach the open corners 49, whatever the polygonal geometry of the box.
  • Figure 8 is a schematic illustration of the folding step immediately before sealing of the corners of an octagonal blank with a machine in accordance with the invention.
  • the folding means comprise a contact profile 7 at a first wall 35' for folding the wall 35' on a side 70 of the counter-mould 10 during its downstroke, and additional contact profiles 72 acting at the walls 35 which are open at an angle.
  • the contact 7 preferably consists of a bar positioned above folding profiles 72 in turn consisting of curved tubular elements with a stretch 73 acting in the vertical direction on the wall 35 and a second stretch 74 acting in a direction at a right angle to the angled side 71 of the mould 10.
  • Figure 8 illustrates the case of an octagonal box, but it shall be understood that the same solution may be applied to boxes with more than four sides, in which the sides of the base form included angles a with different amplitude.
  • Figures 10 - 12 illustrate a polygonal blank in accordance with the invention, in detail an octagonal blank 81, and a polygonal box 88 obtained from the blank.
  • the blank 81 comprises a base 80 and peripheral sections 82 positioned at corresponding sides 83 of the base 80 intended to constitute the walls of the box 88 when lifted.
  • each lateral section 82 is joined to sides 83 which are adjacent to the same included side 86, and each lateral section 82 consists of a central portion 84 joined to the side 83 and lateral portions 85 which can be opened by turning relative to the central section 84 and are smaller than the included side 86, preferably half the size of it.
  • Figure 11 provides a schematic illustration of the blank folding step, in which the folders 7 lift the sections 82, folding them relative to the sides 83, to form the box 88.
  • the lateral portions 85 are folded relative to the portion 84 so as to drawn near one another along intermediate lines M of the wall of the box 88, that is to say, not coinciding with the corner of the box, and preferably coinciding with the median line of the wall.
  • a seal S is applied, for example a heat-sealed strip of the type already described, using sealing heads 4 with a 180° flat pressure profile, that is to say, suitable for appropriately pressing the sealing strip S on the walls of the box rather than at the corners.
  • the blank is a regular octagon, therefore the heads 4 can have a shared approach direction L passing through a centre C of the base so as to apply a balanced stress on the structure of the machine which supports it during the sealing step.
  • the lines L may also not pass through the geometric centre C of the box.
  • a method according to the invention for producing packing boxes with a polygonal plan having a base and lateral sections which can be folded relative to the base comprises:
  • the method preferably involves making at least two seals positioned at the ends of one or more shared lines (L), at right angles to one another if necessary.
