Definitions

  • This invention relates to a gluing device for a box forming machine and to a related gluing method.
  • the invention relates to the technical field of industrial processing of sheets of paper or cardboard for forming finely finished, quality boxes.
  • These boxes are made from specially shaped sheets, called blanks, consisting of a base and a plurality of segments (or panels) connected to the base and foldable relative to it to make up a sidewall of the box.
  • the number of segments of the blank is equal to the number of sides of the base and each segment is connected to a respective side of the base.
  • This type of blank may be generally referred to as “petalled”, like a flower.
  • Blanks of other shapes are also used, however.
  • the number of segments may be equal to (or greater than) the number of sides of the base, but the number of segments connected directly to the base may be less than the number of sides of the base since some of the segments may be connected to other segments.
  • the blank is referred to as "H-shaped” or “T-shaped” or “cross-shaped”, depending on the configuration adopted by the blank when it is laid out flat.
  • the segments are greater in number than the sides of the base, some of the segments are associated with other segments and are foldable sideways to cover the same face of the sidewall of the box, each enclosing a respective vertical edge of that face.
  • the industrial process starting with the blank and ending with the finished box comprises two distinct steps: a step of forming the box, followed by a step of covering the box by applying a covering sheet to it.
  • This invention relates specifically to the step of forming the box.
  • the forming step in turn comprises two successive steps: a first step of folding, followed by a step of sealing or closing.
  • the segments of the blank (which is laid out flat to start with) are folded about the perimeter of the base to form the sidewall of the box.
  • the sidewall of the box defines as many lateral edges as there are corners of the base.
  • At least two are defined by a pair of adjacent lateral borders belonging to consecutive folded segments.
  • box forming machines usually comprise a vertically movable die which is operatively coupled to an inner surface of the base (or of the sidewall of the box) to fold the segments of the blank by causing them to interact with fixed contact members.
  • a step of sealing follows by which the open lateral edges of the box sidewall are joined (that is, closed).
  • sealing occurs by applying sealing strips (called “stay tapes”) to the open lateral edges in order to close them.
  • box forming machines usually comprise sealing heads having respective sealing tape dispensers and applicator elements ("pressers") designed to apply strips of sealing tape to corresponding open lateral edges of the box.
  • the sealing heads can move towards and away from the box between a non-interference position where they are clear of the box and a sealing position where they operate on the corresponding open lateral edges to press the tapes against respective lateral edges of the box, thereby sealing them.
  • the function of the die is that of defining a constraining element operatively inserted snugly into the space inside the box during the action of the pressers, thereby preventing the pressers from deforming the sidewall of the box.
  • hot-melt glue is distributed along the vertical edges of the sidewall of the box, in the interstices formed by the borders of the pairs of segments placed side by side. In practice, this forms a bead of glue which joins the end borders of the joined segments to form the corresponding edges of the sidewall.
  • the pressers are then moved forward to abut against the edges, with the further important function of cooling the glue.
  • the solution which involves spreading hot-melt glue along the gap formed by the borders of the folded segments to form the edges of the sidewall of the box avoids the use of the stay tapes, thereby improving the aesthetic appearance of the box, but is inconvenient because it is particularly complicated (and hence relatively unreliable).
  • the complication is due, for example, to the need to cool the glue and the difficulty of spreading the glue precisely in the interstices.
  • the free sides of some lateral segments are bevelled to define oblique faces contained in the thickness of the blank.
  • the glue is spread on all the oblique faces defined by the bevels (and thus along all the sides of the base and along the sides of the segments) when the blank is laid out flat horizontally (and thus, before the segments are folded to form the vertical edges of the box).
  • a supporting structure configured to enable the blank to move in a feed plane along a longitudinal feed direction to convey it to a gluing station.
  • This method has a twofold advantage: on the one hand it allows production of boxes whose sharp edges have none of the aesthetic flaws due to the stay tapes, and on the other, it avoids the complications associated with spreading hot melt glue along interstices of vertical edges.
  • the gluing system of the special V-grooved blank described in patent document US6029884 has some limitations which make it unsuitable for use in an automatic box forming machine.
  • US2007/199648A discloses a method for producing blanks from cardboards.
  • This invention has for an aim to provide a blank gluing device for an automatic box forming machine which overcomes the above mentioned disadvantages of the prior art.
  • Another aim of this invention is to provide a blank gluing device for an automatic box forming machine which is particularly rapid.
  • a further aim of this invention is to provide a method for gluing flat blanks which is particularly precise and suitable for use in a box forming process implemented by automatic machinery.
  • the gluing device is a gluing device for a box forming machine and is configured to apply liquid glue to a flat blank of paper or cardboard having a base and a plurality of segments connected to the base and foldable to form a box sidewall, where the free sides of the segments, designed to be joined to form the edges of the box sidewall, are bevelled to define oblique faces contained in the thickness of the segments.
  • the gluing device comprises:
  • the supporting structure comprises:
  • the guides are configured to support the end portions of blank segments and, in particular, the guides are spaced from each other to define an empty space between them.
  • the predetermined direction of moving the at least one nozzle is perpendicular to the longitudinal blank feed direction defined by the supporting structure.
  • the device preferably comprises a pair of nozzles which are spaced along the longitudinal direction.
  • the pair of nozzles is positioned at a variable distance along the axis parallel to the longitudinal blank feed direction defined by the supporting structure. This makes changeover particularly easy.
  • the positioning means are provided with adjusters which make changeover of the device particularly quick and easy, as described in more detail below.
  • the locking means are important for the precision and reliability of the device.
  • the locking means guarantee that while the glue is being spread the blank does not undergo deformation or bending (moving under the force of gravity outside the feed plane) which would prevent the glue from being correctly spread on the oblique faces of the edges (it should be noted that the V-shaped grooves formed on the blank weaken it and make it particularly susceptible to such deformation).
  • the gluing device is enabled and the system for applying stay tapes is disabled.
  • the blank is of a traditional type (without V-shaped grooves)
  • the gluing device is disabled and the system for applying stay tapes is enabled.
  • the invention also provides a gluing method for applying liquid glue to a flat blank of paper or cardboard having a base and a plurality of segments connected to the base and foldable to form a box sidewall, where the free sides of the segments, designed to be joined to form the edges of the box sidewall, are bevelled to define oblique faces contained in the thickness of the segments.
  • the method comprises the following steps:
  • the numeral 1 in the drawings denotes a box forming machine according to this invention.
  • the forming machine 1 is a machine for forming boxes of paper or cardboard from flat blanks 2 (of paper or cardboard), having a base 3 and a plurality of segments 4 connected to the base 3 and foldable to form a box sidewall.
  • the forming machine 1 is set up to use special blanks 2 having the features described below (illustrated in Figures 6 and 7 ).
  • the free sides of the segments 4, which are intended to be joined to form the sidewall of the box, are bevelled to define oblique faces 5 contained in the thickness of the segments 4.
  • this special blank (hereinafter referred to simply as "blank”, for short) is made from a sheet on whose top face V-shaped grooves are formed (for example by cutting) along straight trajectories comprising (defined by) the sides of the base 3.
  • the sides of the base 3 and the sides of the segments 4 connected to corresponding sides of the base 3 are also bevelled to define oblique faces contained in the thickness of the base 3 and of the segments 4, respectively.
  • these oblique faces 5, 6 are inclined at an angle of approximately 45 degrees to the plane defined by the blank 2. That way, when the segments 4 are folded relative to the base to form a right angle, the lateral oblique faces 5 of the segments 4 and the oblique faces 6 of the base 3 come into contact with each other.
  • the forming machine 1 (illustrated schematically in Figure 1 ) comprises:
  • the manipulating means comprise a die 8 shaped to snugly occupy the inside of the box and connected to a motor-driven shaft 9 which moves it along a predetermined vertical axis (according to a substantially known method).
  • the invention has for an object the gluing device 10 as well as the forming machine 1 which incorporates the device 10.
  • the device is designed to be connected to a traditional forming machine 1 in order to modify it to make it particularly suitable for forming boxes from the (special) blanks 2.
  • the gluing device 10 comprises:
  • the supporting structure 11 is illustrated in detail in Figures 4 , 8 and 9 .
  • the supporting structure 11 comprises a first and a second guide 14 positioned longitudinally in the feed plane of the blank 2 to define the longitudinal direction of movement of the blanks 2.
  • Each guide 14 is shaped in such a way as to prevent transversal movements of the blank 2 (that is, movements perpendicular to the longitudinal direction of movement and contained in the feed plane).
  • each guide 14 is shaped to slidably support a portion of the blank 2. More specifically, the guide 14 is shaped in such a way as to slidably support a lateral end portion of one of the segments 4 of the blank 2.
  • each guide 14 has an L-shaped or C-shaped profile, the guides 14 being opposed to one another.
  • each guide 14 comprises a ledge 15, which lies in the feed plane, for slidably supporting the lateral portions of the blank 2.
  • each guide 14 comprises a wall 16 perpendicular to the ledge 15 (and to the feed plane).
  • the supporting structure 11 also comprises brackets (not illustrated) for connecting the guides 14 to a frame of the machine 1.
  • the guides 14 and, more generally speaking, the supporting structure 11
  • the forming machine 1 (that is, the gluing device 10) also comprises a pushing element (not illustrated, of per se known type, consisting for example of a finger connected to an actuator) movable longitudinally between the guides 14 to move the blank forward along the guides 14 towards the gluing station.
  • a pushing element not illustrated, of per se known type, consisting for example of a finger connected to an actuator
  • the predetermined longitudinal position is, more specifically, a position of alignment with a predetermined reference axis perpendicular to the feed plane and consisting preferably of the axis (vertical) along which the die 8 moves.
  • the positioning means 17 comprise at least one second pusher 19 positioned at a predetermined distance from the first pusher 18 along the longitudinal direction, the first pusher 18 and the second pusher 19 operating on corresponding borders of segments 4 of the blank 2 (resting on the ledges 15 of the guides 14) from longitudinally opposite sides, that is, in such a way that the first pusher 18 and the second pusher 19 are positioned downstream and upstream of the blank 2 positioned in the gluing station, relative to the advancing direction of the blank along the longitudinal direction.
  • the blank 2 positioned in the gluing station is longitudinally interposed between the first pusher 18 and the second pusher 19.
  • the positioning means 17 of the supporting structure 11 comprise a pair of first pushers 18 and a pair of second pushers 19.
  • the positioning means 17 comprise a total of four pushers operating on both the segments 4 (transversely opposed and resting on the ledges 15 of the guides 14), on the opposite transversal sides of the selfsame segments 4.
  • the second pushers 19, too, are preferably associated with the guides 14.
  • the pushers 18 and 19 are configured to interact with corresponding transversely positioned borders of the blank segments 4 resting on (the ledges 15 of the) guide 14.
  • the pushers 18 and 19 are movable longitudinally between an extended position where they abut against the borders of the blank 2 when the blank 2 is at the predetermined longitudinal position and a withdrawn position where they are away from the blank 2.
  • the pushers 18 and 19 are shown in the extended position in Figure 8 and in the withdrawn position in Figure 9 .
  • the ends of the first pushers 18, that is the pushers 18 positioned downstream define flat portions 20 positioned perpendicularly to the feed plane (to provide a better grip on the borders of the segments 4).
  • the second pushers 19, that is, the pushers 19 located upstream (of the blank 2 positioned in the gluing station), have teeth 21 (pivotally connected to the end of a stem, that is, of a piston, of a corresponding second pusher 19) which are movable between a first operating position where they are spaced from the feed plane of the blank 2 so as not to interfere with blank feed, and a second operating position where they intersect the feed plane so as to define an abutment for the transversal border of the blank 2.
  • the teeth 21 of the second pushers 19 oscillate freely. That way, the blank 2 itself, as it advances along the longitudinal direction towards the gluing station, moves the teeth 21 to the first operating position. Then, once the blank 2 has passed them, the teeth 21 return to the second operating position by gravity (the second operating position being a position of equilibrium into which the teeth 21 tend to move when no external forces are applied to them).
  • the second pushers 19 are also equipped with stops 22.
  • the teeth 21 abut against the stops 22 when they are at the second operating position.
  • the stops 22 are configured to prevent the teeth 21 from rotating in response to a pushing action (for example from the blank 2) backwards away from the gluing station along the longitudinal direction.
  • any other suitable system may be used to allow the teeth 21 to move from the second operating position to the first only when the blank 2 passes as it advances towards the gluing station, preventing this movement in response to a force tending to move the blank backwards in the opposite direction.
  • This adjustment system has two functions.
  • a first function is that of aligning the positioning means 17 relative to a vertical axis (that is, perpendicular to the feed plane which the guides 14 lie in) of the forming machine 1, for example, relative to the vertical axis of movement of the die 8.
  • a second function is that of adjusting the distance (along the longitudinal direction) between the first pushers 18 and the second pushers 19, in order to adapt the positioning means 17 to different box sizes.
  • the pushers 18 and 19 have a predetermined stroke (length of movement of the stem, or piston, relative to the cylinder).
  • the predetermined stroke (fixed) is determined during a preliminary step of calibrating the gluing device 10 (described in detail below).
  • the supporting structure 11 comprises locking means 26 operating on the blank 2 for holding the blank in place so it is in the same plane as the feed plane while it is in the predetermined longitudinal position (determined by the positioning means 17).
  • the jaws of the locking means 26 are configured to interact with the ledges 15 so as to press the lateral end portions (of the segments 4) of the blank 2 (these end portions being operatively interposed between the jaws 27 and the ledges).
  • the jaws 27 are connected to corresponding actuators 28.
