Definitions
- the present invention relates to a forming machine for cardboard boxes or the like.
- Present-day packaging technology uses cardboard boxes which are pre-finished and pre-glued, but still folded, and which are unfolded from a rhomboid shape, i.e. are opened and glued, only at the time when they are to be filled. In this way unnecessary transportation and storage costs, due to the unused volume present inside the empty boxes, are avoided.
- the boxes have a square-shaped central body which is closed at the top by four upper flaps - the lid - and at the bottom by four lower flaps - the base. Since the boxes used have a rectangular cross-section, the flaps are not all the same; both the lid and the base each consist of two small flaps onto which the two larger side flaps are closed and fixed.
- a feeding device designed to remove individually the boxes from the store and convey them to an opening device provided with suction-cup gripping members which open the cardboard box; - a flap-folding device;
- a press designed to press the base for correct gluing thereof .
- Opening of the cardboard boxes is performed by suction cups and guides which act on the external surfaces of the cardboard box.
- the suction cups may be divided up into several groups which are in turn mounted on arms or mechanisms in general which during their movement draw along part of the cardboard box or with the aid of the guides perform the expansion or unfolding from a rhomboid shape thereof .
- the cardboard box is completed by folding over the flaps of the base, after application of a layer of glue, and then compressing them together by means of the press.
- This solution of the known type although functioning in a satisfactory manner, however is unable to achieve a cardboard-box forming speed greater than about 30 units per minute since it does not operate continuously.
- the operation of the suction cups of these machines requires the use of costly and complex pumps for generating the vacuum.
- suction cups and the presence of extraneous solid particles - such as, for example, residue from the processing of the cardboard box or cardboard dust - greatly affect the action of the suction cups, reducing the operating capacity thereof. This causes malfunctions such as jamming or the like and therefore requires continuous monitoring of the state of wear and cleanliness of the suction cups so as to avoid costly machine stoppages.
- the presence of the suction cups is therefore a source of both direct and indirect costs which have a negative effect on the use of the machine .
- Similar machines are also known, in which opening of the cardboard box is performed not by the suction cups but by strong jets of air which are blown laterally into the flattened cardboard box and force it to open owing to the force of the air pressure.
- the object of the present invention is therefore that of overcoming the said drawbacks of the devices of the known type by providing a machine for forming cardboard boxes which is able to open the cardboard boxes continuously and at higher speeds than those which are currently achieved, without this thereby resulting in excessively complex or difficult operation thereof.
- a further object is that of providing a machine which is extremely simple from a constructional and functional point of view and is able to manipulate cardboard boxes without altering or damaging the surface thereof .
- continuous operation is obtained by performing opening of the cardboard boxes in an exclusively mechanical manner by means of introduction of a suitable opening member inside the cardboard box, causing it to pass through an opening obtained by bending slightly the two small flaps of the same side of the flattened cardboard box, i.e. one of the lid and one of the base.
- the two small flaps bend during their rotational movement also the two larger flaps of the opposite side
- the rotation of the flaps is performed making use of the pre-formed folding lines so as not to damage the cardboard box in any way (the step involving formation of the base nevertheless envisages bending the flaps along these folding lines; rotation therefore does not produce any visible deformation) .
- the machine comprises on each side of the box a cam which is arranged along the rectlinear trajectory followed by the flaps and which acts on the smaller of the two flaps, rotating it slightly together with the larger of the two flaps on the opposite side, which is forced to follow the rotation thereof.
- a V-shaped opening is formed between the short superimposed portions of the two larger flaps, which allows easy introduction of any member inside the box so as to force opening thereof.
- insertion of the opening member between the flaps is performed - on each side - by inserting said member in a direction of introduction parallel to the direction of fowards movement of the flaps.
- the opening member comprises a flat lever mechanism which is opened in the manner of a compass as soon as the action of the cams ceases, namely as soon as the opening member is located underneath the two larger flaps of the base and the lid of the cardboard box.
- a flat lever mechanism which is opened in the manner of a compass as soon as the action of the cams ceases, namely as soon as the opening member is located underneath the two larger flaps of the base and the lid of the cardboard box.
- the feeding movement of the boxes is obtained by means of a pushing tooth which also performs the function of extracting the boxes from the store. It is able to assume two positions: a first flat position for removing one cardboard box at a time from the stacking store and a second raised position for pushing the cardboard box, acting on a larger surface so as not to damage the edge thereof .
- the tooth may also be provided with a small wheel or the like which is located on its upper rear surface and is designed to prevent the rear surface of said tooth, during the step of removal of the boxes from the store, from scratching or in any case damaging the cardboard box located immediately above the one which is being extracted.
- Closing of the flaps may be performed by a fixed front flap-closing device which closes the front side flap, the bottom flap and the upper flap, while the rear side flap may be closed by a rotating rear flap-closing device provided with a pusher arm and a flat half-piece in the form of a helix.
- the pusher arm causes closing of the small rear flap, while the helix keeps the large flap slightly raised so that it is unable to interfere with the small flap.
- the front flap-folding device may also be constructed in the form of a fixed contact element which intercepts and closes the front flap, making use exclusively of the feeding movement of the cardboard box.
- the large flap on the opposite side may be guided, in a similar manner, by a fixed guide which keeps it always folded towards the outside of the travel surface of the central body of the cardboard boxes. This solution allows closing of the flaps on the moving boxes in an extremely simple and low-cost manner.
- Pressing of the base may be obtained by means of the association of a conveyor belt, the feeding surface of which is arranged parallel to the base of the box and cooperates with a thrusting piston which presses against the inner base of the box. Said piston moves forwards, parallel to the box, at the same speed as the latter and the supporting conveyor belt, so as not to interfere with the feeding movement of the cardboard box.
- the presser piston may be mounted on a slide moved along a closed-path guiding rail formed with a U-shaped recess in the section where the action on the base of the box is envisaged. In this way the piston travels parallel to the box and enters into the box only in the space intended for pressing of the base.

- FIG. 2 shows a schematic view from above of the machine according to Figure 1, with some details removed so that others may be more clearly visible;
- FIG. 3 to 9 show in sequence the steps of opening of a box;
- FIG. 10 to 12 show schematically the stages of insertion of the opening member inside the flattened box;
- FIG. 13 shows a constructional variant of the device which pushes the cardboard boxes;
- - Figure 14 shows the separating member operating in the store ;
- FIG. 15 shows a constructional variant of the upper member for opening the cardboard boxes.
- the forming machine 1 comprises essentially:
- a member 16 for opening the cardboard box 3 movable between a first closed condition C where it is inserted inside said opening 18 and a second open position D where it at least partially opens the cardboard box 3 from the inside;
- a flap-folding device 6 which is designed to rotate and close the four flaps 8, 9 so as to create a base 14 of the cardboard box 3 ; - a device for applying glue or the like 7 onto the flaps 8, 9 of the base 14;
- the device 4 for extracting and pushing the cardboard boxes 3 comprises a pushing tooth 10 movable between a first lowered position A, where it projects with respect to the surface 11 supporting the cardboard boxes 3 by a thickness S equal to the thickness of the flattened cardboard boxes 3 and a second position B for pushing the cardboard boxes 3 during the following opening steps, where it projects by a greater amount with respect to the surface 11 and has a pushing surface 19 sufficient not to damage the boxes 3.
- the tooth 10 is formed substantially in the manner of an "L" and its movement from the first lowered position into the second pushing position is performed by suitable actuating members not shown.
- the tooth 10 also has on its rear surface 20 a small wheel 21, the function of which is to keep the rear surface 20 inside store 2 at a distance from the cardboard box 3 ' which is stacked immediately on top of the one being extracted. In this way scratching and damaging the cardboard boxes 3 ' with the rear surface 20 of the pushing tooth 10 is avoided.
- the tooth 10 is moved along a closed trajectory which extends from store 2 to the press 12, by means not described since they form part of the known art.
- a displacement member 15 is arranged at the exit from the store 2, said member being composed of a rotating shaft 22 which has a horizontal axis perpendicular to the feeding movement of the cardboard boxes 3 and on which two cams 23 are keyed.
- Each of the two cams 23 acts, upon actuation, causing rotation of the smaller of the two upper flaps 8' downwards.
- the action of the cam 23 bends the flap 8 ' downwards slightly, causing it to rotate about a pre-formed folding line 24 connecting it to the central body 27 of the cardboard box 3. This latter central body 27 is supported by the supporting surface 11 with respect to which the flaps 8, 9 protrude.
- the flap 8' rotating downwards, pushes with it also the larger of the two lower flaps 8" so that the flaps 8' and 8" are displaced with respect to the larger of the upper flaps 9" and the smaller of the lower flaps 9'.
- the opening 18 is therefore located in the cardboard box section where the two large separated flaps 8" and 9" are partially superimposed.
- the member 16 for opening the cardboard box 3 comprises, on each side, at least one thin blade 25 which is arranged slightly below the surface 11 and parallel to the latter and which has, hinged with it, an arm 26 which can be actuated so as to rotate about an axis substantially parallel to the surface 11.
- the two blades 25 are arranged downstream of the cams 23, in alignment with the opening 18 between the flaps 8,9, so that the cardboard boxes, moving forwards, cause the flaps 8', 9' and 9" to pass above and the flap 8" to pass below the blades 25.
- the blade 25 may also be inclined slightly so as to be arranged parallel with respect to the lowered flaps 8 ' and 8". In this way it is easier to intercept the opening 18.
- the surface 11 supporting the cardboard boxes 3 has arranged above it an intercepting arm 28 ( Figure 7) , which is movable between a first intercepting position E where it stops the forwards movement of the front and upper edge 29 of the half-open box so as to force the total opening thereof and a second retracted position F where it moves outside the trajectory of the box 3 so as to allow the forwards movement thereof.
- an upper friction guide 30 is provided, said guide being suspended from a plurality of springs 31 so as to rest lightly on the upper side 32 of the open box. The frictional force generated by sliding of the cardboard boxes along the guide 30 is sufficient to keep them open.
- the upper rear edge of the open boxes is able to be pushed by a pushing serration 56 which moves forwards at the same speed as the tooth 10.
- a flap-folding arrangement 6 is located downstream of the opening member 16 and comprises a rotating flap- folding device 6' and a fixed flap-folding device 6".
- the fixed flap-folding device 6" consists of a plurality of fixed contact guides 33 which force the flaps 8,9 passing through them to follow the preset closing trajectories .
- the rotating flap-folding device 6' comprises an arm 34 which rotates about an axis perpendicular with respect to the support surface 11 and which has, integrally associated with it, a helically inclined segment 25 which precedes it angularly and is designed to move the upper flap 9" away before the rotating arm 34 pushes and closes the rear side flap 8'.
- This device which is extremely simple from a constructional point of view, prevents the rear flap 8 ' from being able to interfere with the upper flap 9" during the step involving closing of the base .
- the lower flap 8" may also be moved away by a second helix 35 but, more simply, it may be kept constantly inclined downwards by a suitable guide which prolongs the action of the blade 25. In this way the lower flaps 8" which remain bent downwards and which pass underneath a suitable guide also help confer stability on the box moving forwards at a fast speed.
- the press 12 presses the outer flaps 8" and 9" against the inner flaps 8 ' and 9 ' so as to ensure the correct distribution of the glue and perfect gluing of the base.
- Said press essentially consists of: - a thrusting piston 36 slidably associated with a support 37 moved by a chain 38 which extends along a closed path;
- the opening member 16 which is closed in its position C, is arranged underneath the surface 11 exactly so as to be located with its thin blade 25 in front of the opening 18.
- the action of the cams 23 ceases when the blade 25 is arranged at least partially into the opening 18.
- the small upper flap 8' freed from the pressure exerted by the cam, reassumes, as a result of the resilience of the cardboard box, its initial horizontal position, therefore being realigned again with the front flaps 9 which are located above the blade 25. In this situation, therefore, the blade 25 presses the larger of the two lower flaps 8" downwards, while the remaining flaps 8', 9', 9" remain higher than the blade
- opening of the opening member 16 is activated and the latter rapidly assumes its open position D ( Figures 5 and 6) .
- the cardboard box 3 or its upper front edge comes into contact with the intercepting arm 28 which stops the travel thereof.
- the opening member closes again, reassuming its initial position C, and inserts itself between the lower flap 8" and the rear flap 8 ' .
- the cardboard box 3 Owing to the relative speed which is thus created between the two opposite sides, the upper side relative to the bottom side, the cardboard box 3 is fully opened, bringing its upper side into contact with the friction guide 30 which keeps the cardboard box 3 open.
- the intercepting arm 28 is now also retracted and thus frees the cardboard box 3 from its blocking action.
- the cardboard box 3 moves forwards further, as illustrated in Figure 9, and continues its travel towards the flap-folding device 6.
- application of the glue in the hot state onto the flaps is performed.
- the fixed flap-folding device 6" acts on the front flap 9', closing it, while the rotating flap- folding device 6', after lifting the upper flap 9", also closes the rear flap 8 ' .
- the gluing step continues in the press 12 where the base of the box 3 is compressed between the thrusting piston
- the thrusting piston 36 guided by the support 37, is pushed towards the inside of the box 3 by the slide 40 which, causing it to be displaced in the support 37, guides it along a U-shaped trajectory.
- the trajectory followed by the piston causes it emerge, at the end of the pressing stage, from the cardboard box 3, leaving it free for the manipulating operations which follow.
- the constructional variant, illustrated in Figure 13 shows an alternative embodiment of the device which is responsible for extracting the cardboard boxes 3 from the store 2 and pushing them along their trajectory.
- This alternative device 104 comprises a separating member 50 which lifts slightly the pack of cardboard boxes 3 of the store 2, which are arranged above the cardboard box 3 to be extracted, so as to create a vertical aperture sufficient to allow an upper end of a vertical pushing arm 51 to pass through.
- the pushing arm 51 is pivotably hinged with an underlying drive chain 53, the trajectory of which extends, underneath the support surface 11, along a substantially vertical plane, and is kept in position by a second arm 54 which is also pivotably hinged with the chain 53.
- the pushing arm 51 is pivotably hinged in turn with the second arm 54 and forms an acute angle with it .
- the kinematic mechanism thus realized keeps the pushing arm 51 perpendicular with respect to the support surface 11 and causes it to extracted finally downwards, by means of translation, keeping it parallel with itself at least in the section where it is contact with the cardboard box which it pushes, as can be clearly seen from the sequence shown in Figure 13.
- the upper end of the pushing arm 51 has, mounted pivotably rotatably on it, an anti-scratch wheel 121 which has the function of keeping the cardboard box to be extracted separated from the remaining boxes stacked in the store 2, preventing scratching of the bottom surface of the cardboard boxes located above.
- the separating member 50 ( Figure 14) may comprise a pair of pushers 52 which are located on the sides of the cardboard box and which are shaped substantially in the form of a wedge . These pusher devices 52 may be made to perform a to-and-fro movement by suitable pusher members
- Figure 15 shows a constructional variant of the upper member which is responsible for completing opening of the cardboard boxes 3.
- the intercepting arm 28 with a curtain-type member 55 consisting of a plurality of strips of resilient material which are suspended in the vicinity of the upper friction guide 30.
- the dimensions and the characteristics of the material of the strips are chosen so as not to damage the surface of the cardboard boxes, while ensuring correct opening thereof.
- excellent results are obtained using strips of plastic material with a width of about 3-7 centimetres.
- fixing of the bases of the cardboard boxes may be performed using means other than the glue described herein, such as staples, metal fasteners or the like.
- Opening of the cardboard box may be performed by acting simultaneously on both sides of the cardboard box in a symmetrical manner (as illustrated) or by acting exclusively on only one of the sides of the cardboard box, for example the side which will form the base of the cardboard box.
- the opening member may act exclusively on the flaps or may, by means of a small additional traslatory movement, act directly on the central body of the cardboard box.
- the cams may also be replaced by other members which are able to obtain the displacement described.
- the invention therefore achieves the objects mentioned.
