Description

[0001] The present invention relates to a method for the production of a box made of sheet material from corrugated cardboard from a scrap comprising a series of at least four rectangular panels ending in a rectangular fastening wing and side extensions designed to at least partially form the bottom of the box, wherein it is made to fold automatically by folding those panels and extensions around the insert of the shape of the complementary interior of the box, the end panel of the series of panels and wings on one side, and the adjacent extensions on the other hand, where they are attached by gluing to form a box.

[0002] It also refers to the execution of a polygonal box.

[0003] Many devices and methods are already known for forming corrugated cardboard boxes around the insert.

[0004] This includes document FR 2767282 which describes the process according to the preamble of patent claim 1.

[0005] Such procedures generally involve bringing the clip onto the insert empirically and adjustably, then wrapping around the insert with a degree of freedom sufficient to position the clip such that the fold lines between the extensions are opposite the edges of the insert.

[0006] Such placement of the clippings around the insert can be performed without too much precision of placing the clippings on the sides of the insert considering the adjustments that will be made during wrapping.

[0007] However, such methods, if tolerant in clipping placement, have disadvantages when it is desirable to change the size of the insert in order to move from one box of the first volume to the box of the second volume.

[0008] They actually require the movement of the elements, wrapping and adhering the wings to the side of the adjacent panel, during the formation of the box, devices (cylindrical pressure plate, stop) to complete the wrapping, so that they can be placed in front of the new edge that closes the box on itself.

[0009] In other words, such devices, if they allow working with systems for capturing clippings with relative precision, cause problems when it is necessary to change the size of the inserts.

[0010] This invention aims to provide a method and a device that are better than those previously known by the requirements of practice, in particular to enable overcoming these means for untimely movement of various elements of compression and complicated bending from the state of the art, while at the same time enabling a high speed, for example greater than 40 or 50 packages formed per minute and an affordable price and obtaining high compactness in the machine.

[0011] For this purpose, this invention in particular starts from the idea of no longer forming a box around the insert so that the side of placing and/or removing the clip is always in the same plane in relation to the frame of the device, as in the state of the art, but to place the clip in relation to the edge or edges corresponding to the glued wing which remain fixed in relation to the frame of the machine (or what is the same for the supply warehouse) regardless of the size of the insert.

[0012] That is, a place is selected for the reference edge of the insert around which the folding of the wing will occur, which forces the cutting machine to place the cut on the insert at different levels and in different planes in the x, y, z coordinate system fixed to the frame of the device.

[0013] This is particularly possible thanks to the method and device according to the present invention, which enable very high precision in taking the clip and its perfectly controlled implementation at the level of placing the clip on the insert.

[0014] In other words, there is no longer a plane for supplying a fixed cut in relation to a reference that represents the frame of the machine, with a folding edge of the wing whose place will change depending on the size of the box, but there is a fixed edge of folding the wing in relation to the frame and the supply position of the variable cutting.

[0015] For this purpose, the present invention in particular provides a method for the production of a box made of sheet material from corrugated cardboard scraps comprising a series of panels comprising at least four rectangular main panels ending in a rectangular fastening wing, which are interconnected by mutually parallel first folding lines, and a first set of side extensions located on one side and connected to the main panels via other folding lines perpendicular to the first folding lines and made to at least partially form the bottom box, said box being made to be automatically assembled by folding said panels and extensions of said first set around an insert of a shape complementary to the interior of the box, an end panel of a series of panels and wings on the one side, and adjacent extensions on the other side, where they are glued together to form said box, in which process

the clipping is removed from the flat pile by lifting the topmost clipping from the constant-height vertical storage with the clipping pile,

after gluing the wings and extensions, the said clip is placed in a predetermined place, and the main panel adjacent to the main panel to which the fastening wing is connected directly or indirectly through the intermediate panel, is placed exactly against the lower or upper side of the insert, so that the lower or upper edges of the insert are exactly against the first fold lines of the facing clip, then the said adjacent panel adheres to the insert by moving up or moving down,

and the panels automatically bend around the edges of the insert, and it is characterized by that

that the wing, previously glued, adheres to the side edge of the adjacent panel by pressing the said wing around the reference edge of the insert on the opposite side to the said lower or upper side, and that in order to form a box of dimensions and/or shape different from that previously configured, the size of the insert is changed while the position of the reference edge of the insert around which the wing is bent remains unchanged in a position that is fixed in relation to the storage.

[0016] Therefore, the folding line of the wing with the adjacent panel coincides with the lower or upper edge of the insert, which is called the reference edge below.

[0017] In preferred embodiments, one and/or another of the following provisions is used:

- the position (pi) of the uppermost clip is measured by a telemetry means, the trajectory of the destacker is calculated as a function of said position (pi) and the movement of said destacker between the clip capture position and the lowered position is initiated, the trajectory for the next (pi+1) clip position during the movement time is calculated, and so on;

the cut on top of the pile is brought to a predetermined height (constant level),

said cut is separated from the rest of the pile by a pre-removal means,

said clip is pushed into its center and kept separate from the rest of the pile in a gripping position,

the pre-removal agent is retracted,

said scrap is picked up by vacuuming with the aid of a destacker,

said clip is moved by said destacking means to place it in a predetermined location,

and the cycle of upper stages repeats with the next uppermost slice.

[0018] By bringing the cut to a predetermined place, the intention is to deposit it precisely directly on the insert or to a place where it will allow its subsequent movement on the insert, without lateral movement in its longitudinal movement thanks to the guides and longitudinal stops located as needed and within reach of the expert to release the removal means from the pile and allow them to take the next cut. - the reference edge that determines the reference edge of the insert is the lower edge of the insert, and the predetermined place is the upper plane of the insert, whereby the panel, adjacent to the panel to which the fastening wing is connected directly or indirectly, is placed on the upper side of the insert;

- the reference edge that determines the reference edge of the insert is the upper edge of the insert, and the predetermined place is formed by the surface located exactly opposite the lower side of the mentioned insert, whereby the panel, adjacent to the main panel to which the fastening wing is connected directly or indirectly, adheres to the lower side of the mentioned insert;

- the cut is pushed with the help of the first set of stops at the reference height X of the pile, and the uppermost cut is separated from the next cut by the second set of stops at the height Y which is at a vertical distance of between 1 and 20 mm from the reference X;

- the pile is retained when the cut at the bottom of the pile reaches a predetermined level, and a new pile is automatically placed in place under the remaining part of the previous pile to ensure continuity of removal from the pile;

- the procedure includes more than thirty cycles per minute;

- separation of the uppermost cut from the rest of the pile is assisted by blowing air over the top of the cut.

[0019] The present invention also provides an apparatus for producing a box of sheet material from corrugated cardboard using the process as described above.

[0020] Also provided is a device for producing a box made of sheet material from corrugated cardboard from a scrap comprising a series of panels comprising at least four rectangular main panels ending with a rectangular fastening wing, which are interconnected by mutually parallel first fold lines, and a first set of side extensions located on one side and connected to the main panels via other fold lines perpendicular to the first fold lines and made to at least partially form the bottom of the box, wherein said box made to be automatically assembled by folding said panels and extensions of said first set around an insert of a shape complementary to the interior of the box, an end panel of a series of panels and wings on the one side, and adjacent extensions on the other side, where they are glued together to form said box, wherein said device comprises

storage for vertical storage of flat cuttings, means for removing the uppermost cutting from said storage by suction,

glue applicator,

a robotic arm for horizontally placing the main panel adjacent to the main panel to which the fastening wing of said captured clip is connected directly or indirectly on the reference surface, means for placing in a predetermined place the main panel adjacent to said main panel to which the fastening wing is connected directly or indirectly exactly against the lower or upper side of the insert, so that the lower or upper edges of the insert are exactly against the first lines of the facing clip, and means for automatically bending the panel around the edges of the insert, and which is characterized by the fact that it includes a means for adhering the pre-glued wing to the side edge of the adjacent panel, by pressing said wing around the reference edge of the insert on the side opposite to said lower or upper side, and that when the reference edge defining the reference edge of the insert is fixed in relation to the frame of the device, it is either the lower edge or the upper edge of the insert.

[0021] When it comes to the lower edge, the predetermined place is the upper plane of the insert, and the means for placing in the predetermined place comprises an arm with suction heads for lowering the main panel adjacent to the main panel to which the fastening wing on the upper side of the insert is connected.

[0022] When it comes to the upper edge, the predetermined place is formed by a surface located exactly opposite the lower side of the said insert, and the means for placing the panel adjacent to the panel with which the fastening wing is connected on the lower side of the said insert includes a conveyor belt with lateral and longitudinal cutout stops.

[0023] Advantageously, the device includes means for telemetric measurement of the position (pi) of the uppermost cut and means for calculating the trajectory of the means of removal from the pile as a function of said position (pi) designed to initiate the movement of said means of removal from the pile between the position of catching the cut and the position of placing it on a predetermined work station, and for calculating the trajectory for the next position (pi+1) of the cut and so on during the time of movement.

[0024] Conveniently, it includes a lifting platform for lifting the stack up to the plane for receiving the uppermost cut,

pre-removal means adapted to separate the uppermost cut from the rest of the pile and means for pushing said cut to shake and hold it apart from the rest of the pile in a position to be gripped by the remover from the pile after withdrawal of the pre-removal means.

[0025] In a preferred embodiment, a means for holding the pile in the upper position when the cut at the bottom of the pile reaches a predetermined level is provided together with a means for automatically placing a new pile. Also advantageously, the upper position holding means includes free stops which pivot between a position in which they slide along the pile and a position in which they carry the bottom of the pile under the action of gravity when they reach the last cut of the pile.

[0026] Advantageously, the device comprises an aid to separate the uppermost cut from the rest of the stack by blowing air over the upper side of the cut, for example through nozzles inclined relative to the surface of the uppermost cut at a relative pressure of between 1 and 2 bar.

[0027] Thanks to this invention and its high precision (which is achieved in particular by the vertical storage that enables the optimization of the system for removing scraps from the pile when properly stacked vertically), it has become possible to greatly simplify the machines and to limit their size.

[0028] Proper vertical stacking means matching with the placement tolerance in the lateral displacement of the pieces plus or minus 1 cm, which is generally the case with the pieces on a pallet that circulates in the usual way for transport.

[0029] Therefore, a system is provided that allows one take of each cut from the pallet or vertical storage correctly assembled, and it will also be possible to perform a series of operations on the cuts between their transfer from the vertical storage and their placement below or on the insert, such as for example to register the bar code, sign, place the RFID chip or bend the wings of the centered cuts on the panels or extensions, to allow the correct placement of the lower box in relation to the upper box when stacked one by one to the other.

[0030] Advantageously, the scrap storage is designed to receive a loaded pallet, for example by simply pushing it onto a lifting platform. Thus, it is suitable to move said pallet and the clippings carried thereon vertically upwards to a viewing and grasping plane, with for example a visual detection means enabling activation and/or stopping of destacking sequences.

[0031] This invention will be more clear after reading the following description of exemplary embodiments which are given below as non-limiting examples.

[0032] Refers to the accompanying draft in which:

Fig. 1 is an axonometric view of an example of an octagonal section, before and after folding of the centering wing, which can be used with the method and/or device according to the present invention.

Fig. 2 and 3 are schematic views, respectively side and axonometric, of the device according to an example of the implementation of this invention.

Fig.4 and 5 schematically show from the front the reference edges fixed in relation to the frame, in the case of the lower edge (Fig.4) and the upper edge (Fig.5), according to the present invention.

Figs. 6 to 10 show side views of the advancing means, the pre-removal means and the de-stacking means according to an exemplary embodiment of the present invention particularly described herein. Fig. 11 to 13 show the final stages of the formation of the box that includes one example of the embodiment of the present invention.

[0033] Fig.1 shows a cut 1 of sheet material from corrugated cardboard comprising series 2 of eight rectangular panels ending with a rectangular wing 3 attached by gluing to the adjacent panel.

[0034] The rectangular panels are connected to each other by mutually parallel first bending lines 4, whereby the panels are formed by four rectangular main panels 5, 6, namely two larger panels 5 and two smaller panels 6 separated in pairs by four intermediate identical panels 7.

[0035] The section 1 also includes a first set or assembly 8 of side extensions located on one side and connected to the main panels via other bending lines 9 perpendicular to the first bending lines 4 and made to at least partially form the bottom of the box, the intermediate panels having no extension.

[0036] The cut 1 also includes a second set 10 of extensions substantially identical to the first set 8 of extensions to form the upper part of the box.

[0037] The extension on both the first and the second sets, namely the extensions 11 and 12 respectively of the sets 8 and 10, are on both sides 13 of the position at least partially inclined towards the outer side of the extension from the second lines 9 of bending or the third lines 14 of bending that connect the extensions of the second set 10 corresponding to the main panels.

[0038] Each set of extensions 8 and 10 also includes other lateral rectangular extensions 15 connected to the small panels via second fold lines and third fold lines.

[0039] In the embodiment described in particular with reference to Fig. 1, extensions 11 and 12 further include respective elements 16 and 17 that will enable the centering of two boxes that are formed in relation to each other, within the framework of superimposing one in relation to the other.

[0040] More precisely, the extensions 11 include, for example, recesses 16, for example square, and the extensions 12 opposite the other set include side wings 18 of a shape complementary to the recesses 16, which, once bent and glued to the corner of the opposite extension (as presented in the second part of Fig. 1 with 19), will allow them to fit into the recesses 16 of the extensions 11 while superimposing one box on another.

[0041] Such an assembly enables mutual centering of the boxes and prevents their relative sliding, especially during their transport on the pallet.

[0042] The second set of 10 extensions serves to form the upper part of the box.

[0043] Fig. 2 shows a device 20 according to one exemplary embodiment of the present invention, for the production of a box from a sheet of corrugated cardboard from a pile 21 of clippings 22 of the type described with reference to Fig. 1 .

[0044] The stack 21 is vertical to a constant level 23.

[0045] It includes a means that allows to remove the uppermost cut 24 in the manner that will be described below, by vertically lifting (arrow 25) and then moving it horizontally (arrow 26) towards means 27, 28 for applying glue by applying the respective lines of glue from below and above in a manner known per se, and to place said cut just above the insert 29. In this embodiment, panel 5 adjacent to the panel 6, with which the fastening wing 3 is connected, is placed exactly opposite and faces the upper side 30 of the insert, so that the upper edges 31, 32 of the insert are exactly opposite the first lines 4 of the folds of the opposite edge.

[0046] Then (in Fig. 2 ) the adjacent panel adheres to the insert by moving up or down (arrow 33). After the automatic bending of the extensions 6, 7 which rotate around the insert by pressing the means 34, known in itself, the wing 3 previously glued with glue 28, adheres to the side edge of the adjacent panel 7 by pressing the said wing around the reference edge of the insert on the opposite side to the said upper side 30 via pressure cylinders 35.

[0047] Fig.3 shows the lower pressure plate 36 made to extend vertically in order to make the lower panel adhere to the lower side of the insert. Other pressure cylinders 37 are provided for the average expert to complete the wrapping. The vertical stack 22 of clippings includes means 38 for preliminary removal, said means 39 for removal from the pile provided by a system consisting of a partially horizontal arm 40 having, for example, branches 41 parallel to each other, a supply of compressed air and the position of suction heads 42, namely, six suction heads (two per arm) for suction capture.

[0048] Fig. 4 and 5 show schematically the principle applied in this invention.

[0049] Fig.4 shows the case in which the cutout 43 is fed from above so that the main adjacent panel 44 is placed precisely on the upper side 45 of the insert 46.

[0050] When the main panel 47 is folded down (arrow 48), the wing 49, which is adjacent to it, is placed on the 50 side towards the corner 51 of the insert located on the other side.

[0051] After wrapping the other two main panels, the last intermediate panel 52 is placed so that the bending line 4 is between the fastening wing 50 on one side and the last intermediate panel 52 on the other side, or against the edges 53, which will thus always be placed in the same place in relation to the frame 54, regardless of whether the insert is a large insert 55 or a small insert 56.

[0052] In this way, all sizes between the small insert 56 and the large insert 55 can be adjusted (see arrows 57), whereby the edge or reference edges 53 remain fixed in relation to the frame.

[0053] In contrast, the clips 43 or 58, of larger or smaller dimensions depending on the size of the insert, are placed at a different place in relation to the frame.

[0054] Such a differential placement is only possible thanks to the high precision obtained in the capture and subsequent placement by the same machine of the cut from the vertical storage on the insert.

[0055] Fig.5 shows another example of the execution of reference edges. Here, the cutouts 59 or 60 are inserted from below, and the edge, corner or reference edge 61 is placed on top of the insert.

[0056] Regardless of whether the insert is a small insert 62 or a large insert 63, the reference edge 61 will always remain in the same place relative to XYZ which is attached to the frame.

[0057] In this way, the fastening wings can be pressed by a pressing means 65 (eg, automatically controlled and/or driven by motors in a manner known per se) which is always in the same place without the need for adjustment and/or displacement.

[0058] In fact, this invention is possible thanks to the high precision in handling the cuttings placed on the insert and/or under the insert.

[0059] In the scouting example described in more detail (see Fig. 6 to 10), this is particularly preferred by means 66 for advancing the stack 22, which includes means for pre-removal.

[0060] In a preferred embodiment, the means of advancement includes a lifting platform 67 (two corners) for horizontally carrying the last cut at the bottom of the pile 21 of cuts 22, and a crane 68 for vertical movement, controlled by a controller 69 that allows lifting the platform programmed according to the removal of cuts, for example every four cuts. This command is controlled by the optical means 70 for measurement. More specifically, this optical means is connected in a manner known per se to a means 71 for telemetric measurement (pi) of the uppermost clip 72 and a means 73 for calculating (microprocessor) the trajectory of the de-stacking means 39 as a function of said position (pi), designed to initiate the movement of said de-stacking means between the gripping position (plane 74) of the clip and the position of placing it on a predetermined workstation, here in this case on the insert, and to during the movement time (in the masked time) the trajectory for the next position (pi+1) of the slice is calculated and so on.

[0061] The diagram as a function of time is, for example, of the following type:

- initialization with the selection of displacement values in the format stored in the database,

- the movement of the robotic arm in the reference warehouse and in the function of moving from the format,

- reading telemetry from the initial position if necessary and/or calculating the initial position, - calculating the current trajectory

- alignment to a reference from the snippet store,

- when the position is reached, then calculation down to the slice according to previously determined values or according to telemetrically determined values,

- suction with suction heads to extract the cutting,

- execution of the trajectory if there was a reading of the telemetry height,

- calculating the return trajectory and otherwise retrieving the trajectory parameters in the database, - breaking the vacuum to drop the clip at the appropriate place,

- execution of the return trajectory,

- and restarting the cycle.

[0062] Means 75 for pre-removal includes a horizontal robotic arm 76 equipped with at least four suction heads 77 for removing clippings 72, wherein the arm is attached to a vertical bar 78 eccentric to the stack, located next to it.

[0063] The rod 78 is guided and attached by a bushing 79 to a chain 80 which operates between position 81 in the phantom in Fig.6 and position 82 in the phantom in Fig.7, grasping and shaking the uppermost cut by means 83 for pushing, position 84 (Fig.8) placing the cut on said means 83 for pushing, for grasping in the plane 74 and position 85 (Fig.9) shaking at a height and laterally enabling the de-stacking means 39 to pick up the clippings 72.

[0064] More specifically, the pushing means 83 includes on both sides of the volume occupied by the pile 22, pipes 86, for example, formed by two pipes having a C-shaped cross-section whose branch opening is located on the side of the pile.

[0065] In these tubes are placed, so that they move translationally and parallel to the branches of the C-shape, respectively, at least two sliding stops 87 formed with metal wings provided in the upper part 88 of the stop 89 to limit the periphery 90 of the clip 72, in order to precisely center it, and keep it on the said stops in a limited position when it moves from its shaking position.

[0066] The stops 87 are, for example, actuated by a system of small spring-return cylinders (not shown) to return to the nominal shaking position at rest.

[0067] They are controlled by the controller 69 to move said stops between their limiting position and shaking position.

[0068] In order to measure the operation of the means for pre-removal and removal from the pile, the pile 22 of cuttings is raised and the platform formed by the supports 67 supporting the last cutting 91. It reaches a point where it is in a position that can automatically start the means 92 for holding the pile in the upper position.

[0069] This means, for example, includes free stops 93 that rotate between position 94 (see Fig. 6 to 9) and position 95 (see Fig. 10) in which they carry the bottom of the pile under the influence of gravity.

[0070] More specifically, the holding means 92 comprises stops 93 formed by a free part which can rotate with respect to an axis 96 integrally with a rod 97 for adjusting the height attached to the frame 98 of the device.

[0071] The stops represent an end stop 99 made to slide along the edge of the pile 100, wherein the stop 99 has, for example, a substantially triangular cross-section forming a point of contact with the edge of the pile.

[0072] When the top of the stopper 99 is no longer in contact with the edge of the pile, because it is too high, the said edge no longer holds and the stopper rotates around its axis 96 under the influence of gravity.

[0073] Then it is adjusted to be placed in the position 101 of the horizontal stop, in which the last cut 102 is at rest, releasing the platform formed by the support 67.

[0074] It is also possible to lower it by activating the crane for vertical displacement to its initial lower position. It can then be replaced on the platform with a new batch of clippings, for example, by pressing on the palette.

[0075] It is then sufficient to raise the pile until it comes into contact with the stops 93, which will then rotate until the last cut of the rest of the pile from above comes into contact with the first cut of the pile from below.

[0076] Therefore, the pile was completely reconstructed without interrupting the loading to make the boxes according to the present invention.

[0077] In order to facilitate the separation of the uppermost cut at high speed, air blowing nozzles (not shown) which are inclined in relation to the surface of the uppermost cut, and which blow air over the upper side of the cut, e.g. under a relative pressure between 1 and 2 bar.

[0078] In the following, the execution of the method and device according to the present invention will be described with reference to Figs. 2, 3 and 4 and 11 to 13.

[0079] From the storage 21 comprising a vertical stack 22 of scraps, the uppermost scrap 24 is brought to a predetermined height (Fig. 2), then said scrap is pushed to its center and kept separated from the rest by means of pre-removal as indicated above and, after withdrawing the means of pre-removal, the scrap (Fig. 2) is grasped by suction by means of removal from the pile and to move the scrap to place it on the station for wrapping around the insert.

[0080] More specifically, the device comprises an arm 40 which allows the placement of the clip in one movement after its lifting, in the assembly station above the insert (Fig. 11).

[0081] The cut 24 or 43 (see Fig. 4) is then placed very precisely on the insert, and more specifically the panel 44 is placed on the upper side 45 of the insert, where the bending lines are placed above the edges of the insert thanks to the high precision obtained, on the one hand, due to the initial starting position of the cut which is on a perfectly calibrated vertical pile and, on the other hand, the ability to achieve perfect placement and movement in tens of millimeters in coordinate system OXYZ in relation to the frame of the device.

[0082] Further, and as shown in Fig. 12 and 13, wrapping is performed around the insert by lowering the lower panel 44' with the pressure plate 36 against the upper panel 44, then by adhering the wings 50 to the intermediate panel 52 around the two lower edges 53 of the insert.

[0083] According to this invention, they are always placed in the same place in relation to the frame, so that (see Fig. 4 ) when the insert is reduced to become smaller (eg insert 56 in Fig. 4 ) in order to adapt to different smaller cuts, the reference edges 52-53 are always maintained in the same place, which greatly facilitates the operation of the device and especially allows to avoid movement in the height of the cylinders 65 and other pressure plates.

[0084] When the assembly and bending of the extensions on the side 110 of the insert is completed, the box 111 is ejected as shown in Fig.3.

[0085] When the stack reaches the upper position, the lower section of the stack exceeds a certain level, the controller detects the inclination of the stop in a manner known by itself.

[0086] Without stopping the device, which continues to empty the stack over the stop, the carriage is lowered and moved into position to receive the new stack that is waiting.

[0087] It is then pushed automatically in a known manner to place it in place below the remainder of the previous stack.

[0088] Then a new pile is raised to integrate with the rest of the previous pile, thus avoiding any break in the continuity of the box formation.

[0089] As it is and as it follows from the foregoing, this invention is not limited to the exemplary embodiment that is specifically described. On the contrary, it includes all variants and, in particular, pieces of different shapes.
