Description

Field of technique

[0001] The present invention relates to a unit and a method for canning (ie arranging within boxes) objects, in particular packaged food products, such as disposable capsules (containing infusion and / or extraction products such as for example coffee, tea, etc., or soluble products, or food products in general, such as jams, creams) or disposable packages of melted cheese, etc.).

[0002] It should be noted that the expression "packaged food products" in the present description, here and hereinafter, refers to products intended for food consumption arranged in suitable packages (so-called primary packaging), of various types and types .

State of the art

[0003] For example, in the case of products of the packaged cheese type, the package consists of a portion of sheet (compatible with food products) enveloping and enclosing the food product.

[0004] On the other hand, for products of the packaged coffee type, the package consists of an envelope containing the coffee powder (so-called capsule).

[0005] The known disposable capsules containing infusion and / or extraction products, used in beverage production machines.

[0006] In the sector in question, namely that of producing capsules, so-called "cartoning machines" of the horizontal type are known.

[0007] A cartoning machine of the horizontal type typically comprises a conveyor belt for cartons on a horizontal plane, already set to volume and pre-glued, and a capsule loading device arranged alongside the conveyor belt. Pushing devices suitably synchronized and phased with the carton conveyor belt push the capsules inside the cartons along a direction parallel to the longitudinal direction of the carton. Such horizontal cartoning machines are generally very long and bulky.

[0008] Cartoning machines of the vertical type are also known, comprising a handling device which moves the boxes already set to volume and pre-glued arranged vertically, and a device for inserting vertically. These vertical type machines are not generally used to insert the capsules inside the boxes, as it is difficult to manage stacks of capsules, or objects in general, arranged vertically.

[0009] A particularly felt need to date is that of having a cartoning machine capable of simultaneously inserting a plurality of objects, for example packaged food products, in a particularly simple and fast way and which is capable of also to operate with boxes obtained and formed starting from flat blanks, which are cheaper than pre-glued blanks.

[0010] In particular, a particularly felt need is that of having a cartoning machine capable of simultaneously inserting a plurality of objects coming from different feeding lines, which has particularly reduced dimensions.

Purpose of the invention

[0011] The object of the present invention is therefore to make available a boxing unit and method that are capable of inserting single-dose capsule-type products into boxes in a particularly simple and fast way.

[0012] A further object of the present invention is therefore to make available a boxing unit and method that is capable of simultaneously inserting a plurality of objects from different supply lines while having particularly reduced dimensions.

[0013] Yet another object of the present invention is therefore to make available a unit and a canning method which are capable of inserting objects, preferably packaged food products (even more preferably of the single-dose capsule type) into the interior of boxes made from flat blanks.

[0014] Yet another object of the present invention is therefore to make available a canning unit which can constitute a valid and effective alternative to the cartoning machines of the existing type.

[0015] Another object of the present invention is to make available a boxing unit of reduced overall dimensions.

[0068] Each capsule insertion device 28 is adapted to hold and move a group of capsules, suitable to be inserted inside the same box.

[0069] Figure 2 shows four capsule insertion devices 28, therefore suitable for inserting groups of capsules into respective boxes.

[0070] It should be noted that, preferably, the plurality of capsule insertion devices 28 is supported by (hooked to) the same support element 58; therefore, preferably, they are moved (vertically or with a horizontal movement followed by a vertical movement) at the same time.

[0071] Alternatively, each insertion device 28 can be operated autonomously.

[0072] It should be noted that, in this way, several groups of products are handled simultaneously (which will fill different boxes, in particular each group of products taken from a filling device 28 will fill a box).

[0073] Preferably, each movable element 29 of each insertion device 28 is equipped with a gripper or one or more suction cups, configured to hold (and move) the capsules.

[0074] With reference to another aspect of the invention, the unit 1 also comprises a station ST5 for closing said blank SB folded to volume arranged on the second receiving seat S2 and containing said capsules to define a box S.

[0075] Preferably, the closing station ST5 comprises a fixed abutment element 30 (of the upper faces of the blank SB) and a movable abutment element 31 (of the upper faces of the blank SB), schematised in Figure 2.

[0076] The closing station ST5 is operationally active in a third predetermined angular position PA6 of said second receiving seat S2 along the movement path of the second seat S2, downstream of the insertion station ST4.

[0077] According to another aspect of the invention, the unit 1 also comprises a first station ST6 for gluing first portions of said blank SB folded to volume arranged on the second receiving seat S2 and containing said capsules, operationally active in a predetermined fourth position of said second receiving seat S2 along the movement path (preferably said predetermined fourth position along the movement path is subsequent to, or partially coincident with, the third position in which the blank is closed or the one in which it is the closing station ST5 is operational).

[0078] It should be noted that, preferably, said first gluing station ST6 provides for gluing together the first and second upper faces SB4 and SB5.

[0079] Therefore, preferably, the first gluing station ST6 comprises a first glue dispensing (or releasing) device 33.

[0080] Preferably the first glue distribution (release) device is movable (preferably along a direction parallel to the first axis X1).

[0086] Said second glue release device 34 is adapted to distribute (release) glue at the third and fourth lateral faces, indicated with SB12 and SB13.

[0087] According to another aspect, the station ST1 for transferring a blank SB from a magazine 4 for feeding blanks SB to said first receiving seat S1 comprises a transfer arm 10.

[0088] The transfer arm 10 preferably comprises a plurality of prongs 11.

[0089] Said prongs 11 are configured (sized and shaped) to pass through the aforementioned cavities 6 defined by the projections 5.

[0090] The transfer arm 10 is movable between a position for withdrawing the blank SB from the feed magazine 4 and a position for releasing the blank SB on said first receiving seat S1 (illustrated in Figure 2), in which said prongs 11 they are arranged inside the aforementioned cavities 6.

[0095] It should be noted that each first suction cup 13A is substantially activated, at the transfer station ST1, in phase relation with the suction cups 12 of the transfer arm 10: in particular, the first suction cup 13A is activated when the suction cups 12 of the arm they are deactivated and the prongs 11 are inserted inside the cavities 6, so as to allow the transfer of the blank SB from the arm 10 to the first seat S1.

[0096] During the transfer of the blank SB from the arm 10 to the first seat S1 the first suction cups 13A of the projections 5 are aligned with the suction cups 12 of the arm 10.

[0097] According to another aspect, the bending station ST2 comprises a die 14, radially movable between an inoperative position away from the first seat S1 (illustrated with dashed lines in Figure 2) and an operative position (illustrated with solid lines in Figure 2) approached to the first seat S1 in which it finds the faces of the blank SB to make a folding.

[0098] It should be noted that this matrix 14 is configured to operate substantially in cooperation with the projections 5, so as to cause a pre-forming of the blank (ie a volume up of the blank SB, in an almost definitive configuration).

[0099] Said die 14 is carried by an arm 19, moved by means of an actuator.

[0100] Preferably, the arm 19 is guided along a predetermined rectilinear trajectory.

[0101] Furthermore, preferably, the arm 19 is an articulated arm.

[0102] The matrix 14 is well illustrated in Figures 3 to 5.

[0103] It should be noted that, preferably, the matrix 14 comprises a first element 14A, adapted to abut the first side face SB2 to bend it (90 °) and a second element 14B able to abut the second lateral face SB3 to operate it a fold (90 °).

[0105] In particular, a first group of further abutment elements of the matrix 14 is active in correspondence with the faces SB10, SB8 and SB6 of the blank SB, to substantially effect a 90 ° bending thereof while a second group of further abutment elements is active in correspondence with the faces SB11, SB7 and SB9 of the blank SB, to substantially effect a 90 ° bending thereof.

[0106] It should be noted that preferably some protrusions 5, in particular the end ones, can be equipped with a retaining element 32 (see Figures 3 and 4): this element 32 is able to hold in position respectively the face SB8 or the face SB9 once it has been bent following the movement of the die 14.

[0107] It should be noted in particular that, in correspondence with the bending station ST2, the blank is substantially bent to be configured as shown in Figure 12: in particular the faces SB2 and SB3 are arranged substantially at 90 ° with respect to the face SB1 while the faces SB10 and SB6 are bent substantially at 90 ° so as to be arranged internally to face SB8 and faces SB11 and SB7 are bent at 90 ° so as to be arranged internally to face SB9 (see Figure 12).

[0108] As regards the faces SB8 and SB9, they are bent at an angle of less than 90 ° and are hooked to the retaining element 32.

[0109] According to another aspect, the unit 1 comprises a deformation (ie yielding) station ST8, operationally active at a predetermined angular position of said first receiving seat S1.

[0110] This deformation station ST8 is operationally active on the first upper face SB4 and on the second upper face SB5, so as to untie connection hinges between the same first upper face SB4 and the second lateral face SB3, and between the same second upper face SB5 and the first side face SB2. (as shown in figure 2).

[0111] More precisely, advantageously, the deformation station ST8 facilitates the subsequent final closing step.

[0112] It should be noted that, according to another aspect, to be sure that the preformed blank SB is perfectly open at the filling station ST4, the unit 1 comprises the station ST10 for opening the upper flaps of the box already described above .

[0113] It should be noted that, preferably, the suction cups 13B and 13C are activated (to hold the blank SB) at the bending station ST2, so as to retain (against the projections 5) the side faces SB2 and SB3 of the blank (pushed from the matrix 14 against the lateral faces of the projections 5).

[0114] The aforementioned angular position of rotation of said first receiving seat S1 in which the deformation station ST8 is operationally active is preferably subsequent (or coincident in a variant not shown) to the second angular rotation position PA2 in which the ST2 bending station.

[0115] Preferably, as illustrated, the deformation station ST8 comprises at least a first and a second abutment element (20,21), movable between an inoperative position away from said first seat S1 (2) and an operative position approached to said first seat S1 in which said abutment elements (20,21) abut the first and second upper faces SB4 and SB5 of the blank SB to yield the connecting hinges with the second lateral surface SB3 and the first lateral surface SB2, respectively.

[0116] According to another aspect, the aforementioned station ST3 for transferring the blank SB folded to volume from the first receiving seat S1 to the second receiving seat S2 comprises a transfer unit 15, movable between an abutment and withdrawal position of the blank SB folded to volume at the first receiving seat S1 and a release position of the blank SB folded to volume at the second receiving seat S2.

[0117] Preferably, the transfer assembly 15 comprises a transfer member provided with a plurality of prongs 22.

[0118] The prongs 22 are equipped with respective suction cups 26, which can be activated to hold the blank SB.

[0119] The prongs 22 are configured to fit into cavities formed between the second reception seats S2.

[0120] More precisely, it should be observed that both the projections 23 and the projections 24 define between them a plurality of circumferential cavities, into which the prongs 22 can be inserted.

[0121] Therefore, the prongs 22 are inserted in the cavities formed between the second receiving seats S2, with the suckers 26 alternating with the suckers 27 of the bottom wall 25 of the second receiving seat S2.

[0122] In particular, once the prongs 22 have been inserted into the cavities, the suction cups 27 of the projections 23,24 and of the bottom wall 25 of the second seat S2 are activated to allow the blank S2 to be retained inside the second seat S2 (and the suction cups 26 of the prongs 22 are deactivated).

[0123] It should be noted that the so-called external surface of the blank SB rests on the lateral walls of the projections 23 and 24 and on the bottom wall 25 which in combination define the second reception seat S2.

[0124] According to yet another aspect, unit 1 further comprises a station ST9 for releasing the box S, formed starting from the blank SB and containing the products, operationally active at a predetermined angular position of the second seat S2 (subsequent to the position of the first gluing station ST6 and preferably following the second gluing station ST7).

[0125] The release station ST9 comprises a pickup arm 40 of the box S containing the products, adapted to transfer the box S to a subsequent line, or warehouse, or container (not shown).

[0126] It should be noted that, preferably, the first rotating member 2 is driven in step.

[0127] Furthermore, preferably, the second member 3 is stepped.

[0128] In the presence of independently motorized carriages, the constant pitch drive of the second member 3 is not necessary.

[0129] It should be noted that the first rotating member 2 and the second member 3 are operated in a suitable phase relationship.

[0130] The invention will now be better described, with reference to the insertion of a group of capsules inside a box formed starting from a blank SB.

[0131] The arm 10, at the transfer station ST1, picks up a blank SB from the feed magazine 4: it should be noted that the suction cups 12 of the prongs 11 are operative on the so-called "internal" surface of the blank SB.

[0132] The arm 10, after having picked up a blank SB, is moved, advantageously linearly, towards the first seat S1.

[0133] More precisely, the tines 11 of the arm 10 are inserted between the projection 5 and the projection 5 (ie between the projections 5 defined along a direction parallel to the first axis X1 of rotation), that is to say in the cavities 6.

[0134] It should be noted that, in this phase, the suckers 13A of the projections 5 are activated and the suckers 12 of the arm 10 are deactivated: in this way the blank SB is held only by the suckers 13A of the projections 5.

[0135] At this point, having completed the transfer of the blank onto the first seat S1, the rotating member 2 is moved, preferably by one step, so as to bring the seat S1 which holds the blank SB in correspondence with the bending station ST2 ( also called box pre-forming station).

[0136] At the bending station ST2, the first and second lateral faces SB2 and SB3 are substantially bent at 90 ° due to the movement of the die 14 and the abutment between the die 14 and said faces (SB2 / SB3).

[0137] More precisely, the elements 14A and 14B of the matrix meet, fold and bring the first and second lateral faces SB2 / SB3 into contact with the lateral walls of the protrusions 5 or in contact with the suction cups 13B and 13C (which are activated to hold the first side face SB2 and the second side face SB3, respectively).

[0138] It should also be noted that the further abutment elements 14C, 14D and 14E provide for the bending of the faces SB6, SB7, SB8, SB9, SB10 and SB11, respectively.

[0139] The blank SB is, at the end of the movement of the die 14, configured as shown in Figure 12.

[0140] Note that, in the bending station ST2, the seventh side face SB10 and the ninth side face SB6 are arranged inside the fifth side face SB8, as well as the eighth side face SB11 and the tenth side face SB7 are internally arranged to the sixth side face SB9.

[0141] It should also be noted that the movement of the matrix 14 causes the coupling of the fifth side face SB8 and of the sixth side face SB9 to the two respective holding elements 32, so as to maintain the folding configuration illustrated in Figure 12.

[0142] It should therefore be observed that the fifth, seventh and ninth side faces SB10, SB8, SB6 (and, in the same way, the sixth, eighth and tenth side faces SB11, SB9 and SB7) are preferably held in position by the element 32 of detention.

[0143] Once the aforementioned step is completed at the bending station ST2, the advancement of a step is carried out and the blank SB is taken to the subsequent deformation (or yielding) station ST8 of the first and second lateral faces SB4 and SB5.

[0144] It should be observed that, in correspondence with the deformation station ST8, the abutment elements (20,21) are moved from the inoperative position away from said first receiving seat S1 to the operative position approached to said first receiving seat S1, in the abutment elements (20, 21) meet the first and second upper faces SB4 and SB5 (as visible in Figure 2).

[0145] Subsequently, the rotating member 2 is rotated to bring the seat S1 with the blank SB folded to volume at the second transfer station ST3 of the blank SB.

[0146] It should be noted that, in this second station ST3 for transferring the blank SB, the transfer unit 15 is moved from the position for abutment and withdrawal of the blank SB folded to volume in correspondence with the first reception seat S1 to the release position of the blank SB folded to volume in correspondence with the second reception seat S2.

[0147] In this way, the transfer unit 15 transfers the blank SB from the first receiving seat S1 to the second receiving seat S2.

[0148] The activation of the suckers 27 of the second receiving seat S2 causes the blank SB to be retained inside the second receiving seat S2.

[0149] Note that the second member 3 moves the second seat S2, containing the blank SB, from the position (so-called "first predetermined position PA4") in which it received the blank SB from the first member 2 to the position in which it is operationally active the ST10 station for opening the upper edges of the box (walls SB4, SB5 of the blank).

[0150] At this station ST10 for opening the upper edges of the box (walls SB4, SB5 of the blank), the upper walls of the box or of the blank SB are found and opened (in this way it is certain that the internal compartment of the capsule loading box is completely open at the next station ST4 for inserting capsules).

[0151] It should be noted that the opening station ST10 is arranged between the blank transfer station ST3 SB and the inserting station ST4; in the example illustrated the opening station ST10 is located between the second curvilinear portion 54 and the first rectilinear portion 51.

[0152] The member 2, by continuing to advance the seat S2 along the movement path, makes the seat S2 reach the capsule insertion station ST4. At the capsule insertion station ST4, the capsule insertion device 28 is activated to release a row of capsules inside the box.

[0153] More precisely, the support element 58 is moved vertically, which determines the vertical movement, simultaneously, of all the insertion devices 28.

[0154] It should therefore be observed that, at the filling station ST4, the simultaneous filling of a plurality of boxes is carried out, each arranged under a device 28 for insertion inside respective second seats S2.

[0155] Advantageously, the insertion device 28 is adapted to insert the caps inside the blank SB according to a (vertical) insertion direction which is perpendicular to a longitudinal direction of the box S. This allows extremely short strokes to be obtained, therefore reduced insertion times.

[0156] It should therefore be observed that the blank SB is loaded with a predetermined number of capsules.

[0157] Subsequently, the second member 3 is kept further active to advance the blank SB along the movement path to the closing station ST5.

[0158] The first and second upper faces SB5 and SB4 are folded at this closing station ST5.

[0159] Note that the bending of the first and second upper faces SB5 and SB4. it can also take place in different positions of the movement path of the second seat S2.

[0160] In particular, it should be noted that the second upper face SB5 is folded by means of the fixed element 30, while the first upper face SB4 is folded by means of the mobile abutment element 31.

[0161] Preferably, the first upper face SB4 is folded by means of the mobile abutment element 31 in a position of the second seat S2 along the movement path further upstream (with reference to the movement of the second seat S2) with respect to the position in which the second upper face SB5 is folded by means of the fixed element 30.

[0162] It should be noted that the movable abutment element 31 is movable between an inoperative position of non-interference with the first upper face SB4 and an operative position of interference with the (and abutment of) the first upper face SB4.

[0163] In a subsequent angular position (or according to a different variant, in the same angular position in which the closing station ST5 is operative), the first and second upper faces SB5 and SB4 are substantially glued together.

[0164] More precisely, as illustrated in Figure 2, the first gluing device 33 distributes a layer of glue on the first upper face SB4, even more precisely on an external surface of the first upper face SB4.

[0165] The first device 33 is preferably movable (preferably parallel to the direction of the first axis X1 of rotation) to distribute a layer of glue in a plurality of points (continuous or discontinuous) of the external surface of the first upper face SB4.

[0166] Alternatively, the first device 33 can be fixed, for example with a plurality of glue dispensing points.

[0167] It should be noted that the third and fourth lateral faces SB12 and SB13 are inserted inside the fifth SB8 and sixth SB9 lateral faces respectively.

[0168] It should be noted that, preferably, the unit 1 also comprises an abutment device 35 for the first SB5 and the second SB4 upper face, operating downstream of the first gluing station ST6.

[0169] This device 35 is preferably movable between a position of non-interference with the first SB4 and the second SB5 upper face and an operating position, in which it encounters the second upper face SB5 to push it into contact with the first upper face SB4, in the final closing position.

[0170] It should be noted that the unit 1 may also comprise an element (not shown) or guide, suitably shaped, configured to keep the second upper face SB5 in contact with the first upper face SB4 in the final closing position, arranged and operative downstream of the mobile feedback device 35.

[0171] Preferably, said abutment guide element or guide is operative on the second upper face SB5 during the rotation of the second member 3 towards the release station.

[0172] In the next step, the blank SB is brought to the second gluing station ST7.

[0173] At this second gluing station ST7, the second glue release device 34 glues the fourth side face SB13 on the sixth side face SB9 and the third side face SB12 on the fifth side face SB8.

[0174] It should be noted that the unit 1 preferably also comprises a pair of abutment elements, acting on the fifth and sixth side faces SB8 and SB9 after gluing by the second gluing device 34, to maintain the fifth and the sixth side face SB8 and SB9 respectively pressed against the third side face SB12 and the fourth side face SB13 (in order to allow adhesion by the glue).

[0175] It should be observed that the blank SB put to volume, containing the capsules and closed by gluing (thus defining a package or box S) is brought to the release station ST9.

[0176] The pick-up arm 40, in this release station ST9, grasps the box S and detaches it from the second seat S2 (in correspondence with this grasping operation, the suction cups 27 operating on the second seat S2 are deactivated).

[0177] Preferably, at the release station ST9, at least one sensor 59 is provided which is suitable for verifying one or more parameters inherent to the box.

[0178] Preferably, said sensor 59 is a camera.

[0179] Preferably, said camera allows to detect the closure and / or the correct gluing and / or verify the affixing of the marking and / or the presence and / or the shape of the box.

[0180] With reference to figures 10 to 16, it should be noted that these figures represent the folding, closing, gluing steps performed in the different stations of unit 1.

[0181] Advantageously, the boxing unit 1 for packaged food products allows to insert, inside different boxes, products coming from several feeding lines (L1, L2, L3, L4) (these products can be the same or different).

[0182] It should in fact be observed that, preferably, the insertion devices 28 are operationally active for the release of capsules simultaneously on several underlying boxes.

[0183] In this way, where there are several lines (L1, L2, L3, L4) for feeding packaged products, it is possible to pack them by means of a single product canning unit 1 as described above.

[0184] It should be noted that, in this way, the spaces on the floor are reduced and the operational flexibility of the machine is also increased, as it is possible to fill boxes with different products at the same time (for example some boxes with products from the first line , other boxes with products from the second supply line, and so on).

[0185] It should be noted that a machine is also defined for making boxes containing disposable capsules containing product, preferably disposable capsules containing infusion or extraction product, comprising a plurality of stations configured to operate in phase, including at least: a station for feeding rigid bodies inside corresponding seats of a transport element; a station for filling the rigid bodies with a predetermined quantity of product; a station for closing the rigid bodies, in particular of an upper mouth of the rigid body, with a section of closing sheet for forming capsules; an outlet station which picks up the capsules from the respective seats of the transport element; And the canning unit 1 described above.

[0186] In addition to the stations listed above, the machine for making capsule boxes can comprise further stations, such as, for example, one or more weighing stations, one or more cleaning stations, one or more control stations, and , depending on the type of capsules to be packaged, one or more stations for applying filter elements.

[0187] It should be noted that, advantageously, as illustrated in Figure 2, each second seat S2 is defined by elements 100A and 100B facing each other laterally.

[0188] These elements 100A and 100B, according to a non-limiting embodiment, are movable in reciprocal moving away / approaching, so as to allow the box arranged between them to be unloaded more easily and safely.

[0189] With reference to Figure 2, it should be noted that the product supply lines L1, L2, L3, L4, L5 terminate, at the insertion devices 28, in a product release region (below the support element 58).

[0190] The canning unit 1 comprises, in correspondence with said product release region, a plurality of channels (each associated with a line L1, L2, L3, L4, L5), which can be opened and closed at the bottom or with a bottom openable and closable.

[0191] It should be noted that the insertion devices 28 are active in correspondence with said channels.

[0192] More precisely, said channels are defined by lateral sides 44 (defining a lateral containment surface of the articles PR) and by one or more bottom elements 43 (defining a lower supporting surface of the articles PR).

[0193] Preferably, said bottom elements 43 are movable between a closing position of the bottom of the channel, in which they support the articles PR present in the channel, and an opening position of the bottom of the channel, in which they allow the insertion devices 28 to move the articles PR vertically (passing through the region in which the bottom elements 43 are arranged in the closed position).

[0194] More precisely, when the bottom elements 43 are in the closing position of the bottom, the articles PR coming from the supply lines are inserted inside the channel and the insertion devices 28 subsequently take them out, by means of the suckers 29.

[0195] On the other hand, when the bottom elements 43 are in the opening position of the channel bottom, the insertion devices 28, which have already picked up the articles PR by means of the suction cups 29, are moved vertically to release the articles PR into the underlying second ones seats S2 in transit in the straight section 51 of the transport element 50.

[0196] Figure 2 illustrates two bottom elements 43 for each channel. Preferably, said elements 43 of Figure 2 are movable horizontally, in mutual approach (closing position of the bottom of the channel) or moving away (opening position of the channel).

[0197] An advantage of the present invention consists in having made available a canning unit 1 which is particularly simple to use and which can constitute a valid alternative to the canning machines / units of the existing type.

[0198] A further advantage of the present invention is that of making available a machine 1 which is particularly fast, capable of operating at particularly high operating speeds, and of reduced bulk.

[0199] A method of canning packaged food products (in particular of capsules containing extraction and infusion products) is also defined, comprising the following steps: prepare a planar SB blank provided with a plurality of side faces (SB2, SB3, SB6, SB7, SB8, SB9, SB10, SB11, SB12, SB13), with at least one upper face (SB4, SB5) and a lower face or bottom (SB1); providing a first rotating member 2 provided with at least one projection 5 (defining a first receiving seat S1); provide a second member 3 equipped with at least a second receiving seat S2 (preferably defined by a pair of projections (23, 24) and by a bottom wall 25 interposed between said projections (23,24)) and an element 50 of transport to which said at least one second receiving seat S2 is fixed, said transport element 50 developing to define a closed loop movement path of the second receiving seat S2 having at least a first rectilinear portion 51; coupling said blank SB, preferably in planar configuration, to the projection 5 in a first predetermined angular rotation position of the first receiving seat S1; folding at least one side face (SB2, SB3, SB6, SB7, SB8, SB9, SB10, SB11, SB12, SB13) into a second angular position of rotation of the first receiving seat S1 by means of a matrix 14; transferring said blank SB from the first rotating member 2 to the second member 3, at a third angular rotational position PA3 of the first receiving seat S1 and a first angular rotational position PA4 of the second receiving seat S2; inserting said packaged food products inside the blank SB with the blank (SB) held in the second seat S2; close, advantageously by gluing, the blank SB to define a box S.

[0200] Advantageously, the step of closing the blank SB comprises the step of folding a first and a second upper face (SB4, SB5), and possibly other side faces, and gluing them, so as to close the blank containing the food products packaged and define a box S.

[0201] According to another aspect, the step of transferring the blank from the first rotating member 2 to the second member 3 comprises a step of arranging the blank SB inside the second seat S2 so that the surface of the blank SB which faces towards when the blank SB is coupled to the projection 5 of the first receiving seat S1, the outside faces the inside of the second receiving seat S2.

[0202] According to another aspect, the method comprises a step of yielding at least one connection hinge between upper faces and respective side faces of the blank SB.

[0203] According to this aspect, preferably the method comprises a step of deforming connecting hinges between a first side face SB2 and second upper face SB5, and second side face SB3 and first upper face SB4.

[0204] Advantageously, the step of inserting the packaged food products inside the blank SB provides for inserting the packaged food products according to an insertion direction which is perpendicular to a longitudinal direction of the box S.

[0205] A further or second embodiment will now be finally described (illustrated in Figures 17 to 19), alternative to the first embodiment.

[0206] It should be noted that, according to this second embodiment, each first seat S1 is movable between a first and a second position. Preferably, each first seat S1 is radially movable with respect to the first axis X1 of the first rotating member 2.

[0207] Preferably, each projection 5 which defines the first seat S1 is movable along an arm 41.

[0208] Each arm 41 is carried radially by the first rotating member 2.

[0209] Preferably, each first seat S1 is radially movable with respect to the first axis X1 of the first rotating member 2 between a first position close to the rotation axis X1 of the first rotating member 2 and a position away from the rotation axis X1 of the first rotating part 2.

[0210] As can be seen from figures 17 to 19, the first seat S1 is arranged in the position away from the axis of rotation X1 of the first rotating member 2 in correspondence with the first position PA1, where the blank is transferred from the magazine 4 to the first S1 location itself.

[0211] In particular, in correspondence with the first angular position PA1, in order to transfer the blank from the magazine 4 to the first seat S1 itself, the first seat S1 is moved so that it is arranged in the removed position: in this removed position the suction cups arranged on the upper face of the first seat S1 are in fact in contact with the surface of the blank SB, so as to be able to hold the blank itself.

[0212] The first seat S1 is then moved towards the first approached position, thus taking the blank from the feed magazine 4. Basically, in the embodiment illustrated in figures 17 - 19, the first seat S1 in the first angular position PA1 defines the first transfer station ST1.

[0213] It should be noted that, following the transfer of the blank from the magazine 4 to the first seat S1 itself, the first seat S1 is moved from the position away from the position approached to the first axis of rotation X1.

[0214] It should also be noted that, according to the embodiment illustrated in figures 17 - 19, the abutment elements 20 and 21 are associated with (ie carried by) each first seat S1.

[0215] In particular, each first seat S1 is equipped with its own feedback elements 20 and 21.

[0216] It should be noted that, according to this embodiment of figures 17 - 19, the matrix 14 can be stationary, i.e. fixed to the frame, or it can be mobile (preferably radially with respect to the rotation axis X1 of the first rotating member 2 ). It should be noted that, in the case in which the matrix 14 is stationary, the first seat S1 is moved at the station ST2 from the approached position to the removed position, so as to bring the blank SB into contact with the matrix 14 itself. It should also be noted that in this case the bending of the faces to allow the blanking SB to be made up is done according to the same methods illustrated and described above with reference to the first embodiment.

[0217] Following the volume up of the blank SB by means of the matrix 14 (mobile or stationary), the abutment elements 20 and 21 can advantageously operate, to deform the upper faces SB4, SB5 of the blank itself, or in other words to yield the connecting hinges between the first upper face SB4 and the second side face SB3, and between the second upper face SB5 and the first side face SB2.

[0218] The abutment elements 20, 21 can operate in any angular position of, that is, along any arc traveled by the first seat S1, downstream of the bending station ST2 and upstream of the second transfer station ST3.

[0219] In the embodiment of figures 17 - 19, therefore, each pair of folding elements 20, 21 defines the deformation station ST8.

[0220] It should also be noted that, preferably, after the volume of the blank SB has been made up, the first seat S1 is moved from the removed position to the approached one.

[0221] It should also be noted that, in correspondence with the second transfer station ST3, the first seat S1 is moved from the approached position to the distanced one, so as to release the blank SB which has been set up in the second seat S2 (see figures 17 - 19).
