Description
- The present invention relates to the technical field concerning the machines or automatism used for packaging articles into carton boxes, particularly refers to a machine for packaging articles inside boxes made from a flat blank or a flat tubular blank.
- Packaging machines for various shaped articles are known, constituted by the following elements: a packaging carton magazine; a group for picking up the cartons; a forming group fit for erecting boxes from flat blanks or flat tubular blanks; a stacker group for articles to be packaged, displaced vertical o lateral with respect the operative axis of the machine; a group for inserting the grouped articles into boxes; a group for picking up the formed boxes; a group for closing the inner flaps of boxes; a group for gluing the flaps; a group for closing the external flaps and finally a group for exiting the boxes so packaged.
- The main drawback of the known machines consists in using several devices, and therefore several machines, for handling the flat blanks or the flat tubular ones, so that these machine are fed with a single type of blank and therefore are not versatile at all.
- Further drawback of the known machine is that the blank picking group and the box forming group are slidingly supported below these latter so that, when the articles to be packaged or the boxes are broken, the picking and forming groups and the related carriages are dirty so that the machine must be stopped for a long time for removing the broken articles, for cleaning said groups and for restarting the machine.

- figure 10 and 11 show each a schematic view of the machine operative cycle using two different flat blanks.
- With reference to figures 1 to 6,
numeral 1 refers to a machine forpackaging articles 2 insideboxes 4 made from a blank 3. - The blank has a series of longitudinal 3a and transversal 3b scores and a series of
cuts 3c defining front 8a and rear 8b wings andlateral end flaps 9, lower 9a and upper 9b. - This machine essentially includes a
magazine 5, a mechanical handling means 10 and afinal closing station 30, an exit station 6 of the formed boxes and an unit fit to control and command the synchronous moving of the all operating elements of themachine 1. - The
magazine 5, designed to contain a plurality ofblanks 3 stacked in such a way to be picked up from the stack bottom, is provided with regulating means of the width in such a way to adjusted for the different size of the blanks stored therein. - In particular in figures from 2A to 3B is shown an handling means 10, fit for picking up flat tubular shaped
blanks 3 from themagazine 5, which is supported in a rotating way by acarriage 7 sliding on a series ofguides 11 parallel to the operative axis of themachine 1 in such a way that the handing means 10 extends from theguides 11 and can alternatively slide among themagazine 5 and the exit station 6. - The handling means 10 includes a pivoting
body 12 pivoted to thecarriage 7 and supporting at the upper end abase 13 provided with first suction means 15 of the suction cup type, to which pivoting erectingmembers 14 are hinged, provided with second suction means 16 of suction cup type. - Rotating means 20 include a
base 21a fixed to the handling means 10 and amovable base 21b supported in a sliding way by this latter and fit to be spaced from thefixed base 21a by virtue of known spacing means, of a driven screw type, or moved manually by means of an hand wheel, and on the basis of different operative needs depending on the side wall transversal size of each blank 3. - The bases, fixed 21a and movable 21b, support in a rotating way respectively an inner 22a and outer 22b brackets, fit for folding respectively the
rear wings - Figures 4A and 4B show said
closing station 30 that includes aframe 38 supporting a double couple ofconveyors 55 fit for carrying saidbox 4 in correspondence of the passage from the feeding condition I to the exit station 6. - The
closing station 30, shown in figures 4A and 4B, further includes lower folding means 40 that are constituted by a couple offirst plates 41 hinged to the sides of eachconveyor 55 and are fit to tilt theside flaps 9, lower 9a, during the passage from a non interference horizontal condition NI to an interference condition II with these latter. - The distances between the
first plates 41 and thesecond plates 51 are adjustable according to the longitudinal size (height) of the box side walls, by means of known devices of a powered screw type or manually operated by a hand wheel screw type. Similarly, thefirst plates 41 and thesecond plates 51 are mutually spaced according to the transversal size (thickness) of the blank side walls. - The upper folding means 50 are constrained in a sliding way to the
frame 38 throughvertical guides 39 and can be spaced from the lower folding means 40 according to the side wall size of each blank 3 adjacent to the one that touches theconveyors 55. - Fixed folding means 35 are in the
closing station 30, and are constituted by a couple ofcurved brackets 35a placed between the same station and the hand means 10, having the curved edge facing this latter. - The
closing station 30 further includes agluing group 60, placed downstream the fixed folding means 35 and upstream the lower 40 and upper 50 folding means, and are fitted to sprinkle with glue thefront 8a and rear 8b wings of the blank 3 erected in an unclosed box by the handling means 10. - The operation of the
machine 1 is controlled by the running software program executed by the control and command unit and includes the following sequence of operative conditions. - At first the handling means 10 is displaced into the picking up condition P, in which the
suction cup base 13, when activated, engages the end blank 3 of the stack in the magazine 5: in particular thepivoting body 12 is rotated of about 80° with respect to the vertical axis, so that thebase 13 is parallel to the plane formed by theflat blanks 3 stacked in themagazine 5. - Therefore during the passage from the tilting condition R, the handling means 10 is moved toward the
closing station 30 and rotate its head until thebase 12 become vertical and the blank is horizontal. Thepivoting erecting members 14 are then activated and tilted onto the side wall of the blank 3 adjacent to the one horizontally hold by thesuction base 13. The second suction cup means 16 are then activated and, with an opposite movement, thepivoting erecting members 14 come back orthogonal to thebase 13 and the blank 3 is erected by stretching along thelongitudinal scores 3a. - The command unit therefore drive the handling means into the forming condition F in which the folding means 22 tilt the outer
rear wing 8b of the blank 3, by pivoting the movableouter base 21b. A this moment, as schematically shown in figure 4, thearticles 2 are inserted, in a known way, by means of pushing means into the erected blank box up to thewing 8b. - Under the direct control of the command unit, the following operation are sequentially activated: activation of the
fixed base 21b of the rotating means 20 for folding the innerrear wing 8b; activation of the feeding condition I in which the handling means 10 put thebox 4 into theclosing station 30, that, through its movement toward theclosing station 30, cause thefront wings 8a interfere with the fixed folding means 35, that fold them inwards the erected blank box; activation of thegluing group 60 that sprinkle warm glue on thefront 8a and rear 8b wings; activation of the lower 41 and upper 51 plates that fold thelateral flaps 9, respectively lower 9a and upper 9b, against thewings - Now the
box 4 is fully formed and filled witharticles 2 and then it is carried from theclosing station 30 to the exit station 6 by activating theconveyors 55. - It is important to notice the extreme versatility of the
machine 1 and in particular the hand means 10, by virtue of its extension from the its moving members (i.e.,guides 11 supporting the carriage 7), keeps free, checkable, clean and clearable the underlying portion from anything, for instance accidental asbroken boxes 4 and/orarticles 2 during the forming condition F of the blank 3 and/or during the box filling with said articles. - Besides the "handling" of the blank 3, of the erected blank, of the formed and filled box with the
articles 2, is always operated by the handling means 10 without transferring the blank and the successive filled box to other members (for example conveyor chains, shapes, forming heads, etc.) so that the secure keeping of the blank-box and then its "squaring" is guarantied during each operative step of forming-filling-carrying of thebox 4. That means the safe handling of the blank-box and then the reduction of themachine 1 failure, the increase of its reliability and, mainly, the independence from the quality and the type of the blank carton: indeed it can be used thin paperboard for small boxes till very thick corrugated cardboard. - A second embodiment of the
machine 1 is shown in figures from 6A to 11, in which the mechanical hand means 11 and theclosing station 30 include further members fit for forming theboxes 4 made fromflat blanks 3 with which it is possible to make the so-called "wrap" package, as shown in figure 11. - The mechanical hand means 10 provides that the
base 13 is hinged not only with thepivoting erecting members 14, called rearpivoting erecting members 14b, but also with a further frontpivoting erecting members 14a, having second suction cup means 16. These pivoting erecting members, frontal 14a and rear 14b, are coplanar with thebase 13 and are fit to engage the wall of free blank in themagazine 5, by means of thesecond suction cups 16, in correspondence of the picking up condition P. - In this case, the
closing station 30 further includes free wheel means 90 connected to theframe 38 of thestation 30 and fit to fold the side wall, so providing thecover 18 of said blank formed during the passage of thebox 4 through saidclosing station 30 toward said exit station 6. At least afolder 95 is provided, hinged at theframe 38 facing the handling means 10 and fit to tilt thefree wing 18a of saidcover 18 onto a side wall of said blank 3. - The
closing station 30 comprises besides thefirst gluing group 60, fit to sprinkle thefront 8a and rear 8b wings with glue, also asecond gluing group 65 fixed to theframe 38 by means of abar 66, vertically movable, by virtue of a motor drive 67, so to be placed in correspondence of the free tab18a of thecover 18 for sprinkling glue thereon. - About this second embodiment, the operation of the machine are the same for forming the boxes so called "American" carried out from a closed flat tubular blank, with the difference that the mechanical hand means 10 pass from the picking up condition P to an extraction condition E, in which said pivoting
body 12 is horizontal and thebase 13 and the erectingmembers base 13 and said blank 3 is "U" shaped. - Besides the
cover 18, still erect in the loading condition C ofarticles 2 inside this "U" blank-box, is pull down over this latter by means of the free wheel means 90 and finally thefrontal folder 95 presses thefree edge 18a of thecover 18 onto the adjacent side wall, after glue sprinkling inside saidfree edge 18a due to thesecond gluing group 65. - The commands and controls for making these operations are controlled by the control and command unit software that commands the actuators for synchronising their activation and deactivation.
- The figure 10 shows a third embodiment of
machine 1 in which theblanks 3 have a couple of laterallower flaps 9 havingfree edge 9c designed to form a so-called "display" box. - In this third embodiment, the
machine 1 has ashape 80, see figures 7A-8C, sliding vertically through lift means 81 fixed to theframe 38 of the same station, and the upper folding means 50 have hingedplates 51 fit to tilt inwards the "U" blank during the passage through theclosing station 30 for tilting thefree edge 9c. - The operation of the
machine 1 according to this third embodiment is similar to the second embodiment with the difference that at the end of the forming condition F of the blank 3, this latter is "U" shaped and the lateralrear wings 8b are both folded by means of rotation of the inner 22a and outer 22b brackets. Another variant is that, after the condition F, a further condition FF is carried out, by means of the control and command unit, in which the mechanical hand means 10, during the movement inside theclosing station 30, let thelateral front wings 8a to tilt; therefore, when theclosing station 30 is reached, it release the "U" folded blanks with thelateral front 8a and rear 8b wings tilted, in such a way that theshape 80 is inserted into said "U" from the top so to be a shape for thebox 4 and the lower folding means 40 tilt thelateral flaps 9 towards saidshape 80. - The
shape 80 is then raised from the blank-box and the mechanical hand means 10 carries back the so formed box in correspondence of the loading condition C of the articles inside therein. - A this moment, the control and command unit operate again the mechanical hand means 10 that releases the
box 4 filled witharticles 2 onto theconveyors 55 for completing the closing steps of thebox 4 through the glue sprinkling on thefree edge 18a of thecover 18 by means of thesecond gluing group 65 and the upper folding means 50 fold inwards said free edge of theside flaps 9 and the free wheel means 90 tilt thecover 18 and finally thefrontal folder 95 folds thefree edge 18a onto the side wall of the box, as for the second embodiment of themachine 1. - It is advantageous to notice that the mechanical hand means 10, since operated by said control and command unit, is stopped and moved in any direction between said
magazine 5 and saidstation 30, in such a way to make themachine 1 extremely versatile, so, for example, to displace the blank or the box to be formed or just formed in front of eventual labelling or control stations, etc. - The main advantage of the invention is to provide a machine for packaging articles inside boxes made by a mechanical hand device designed to avoid the machine stops in correspondence of articles and/or boxes breaking during the packaging.
- Further advantage is to provide a machine constituted by a reduced number of functional group, and fit to work with both a flat blank and a flat tubular blank.
- Another advantage is to provide a machine fit for working with any type of blank carton because it is provided with a single mechanical hand and forming device of the box that avoids the passage of the box from a group to another in correspondence of the forming and the filling of this latter.
