[0004] Field of technique
[0005]
[0006] The present invention concerns a machine and a box forming method useful for forming boxes of rectangular or octagonal configuration with a fully or partially closed bottom and an open top provided with a reinforced edge from a plurality of folded and stacked boxes. vertical position.
[0007] Background of the Invention
[0008]
[0009] Boxes of rectangular or octagonal configuration are known that have side walls, a totally or partially closed bottom formed by several flaps that extend from lower edges of the side walls folded and glued together, and an open upper part delimited by edges. upper side walls.
[0010]
[0011] It is usual that, during the production of such boxes, to facilitate transportation and storage, a plurality of folded and stacked boxes are available which must be individually unfolded and conformed to the aforementioned rectangular or octagonal configuration with the bottom partially or totally closed and top open. Folded boxes can be stacked horizontally or vertically.
[0012]
[0013] Each box is made up of a die-cut sheet made of corrugated cardboard or similar and provided with split lines that define a plurality of panels corresponding to the side walls and to the bottom flaps, where the panels corresponding to the side walls are connected to each other by its lateral edges forming a strip, and where the lateral edges of the first and last panels of the strip are also connected to each other so that the strip constitutes a closed ring.
[0014]
[0015] In the folded position, the closed ring is flattened so that one half of the panels overlap the other half of the panels. It is usual that in the folded position, and depending on the box configuration, the creased lines that define one half of the panels do not coincide with the creased lines that define the other half of the panels.
[0016] Boxes of this type, which are called "pallet boxes" or "palots", once formed, are stackable, but they are not stacked directly on top of each other, but each box is arranged on a pallet forming a set of box and pallet, and the box and pallet assemblies are stacked on top of each other. The compressive strength of the box in the vertical direction is high since the corrugated cardboard grooves are oriented in the vertical direction. However, the resistance to expansion is lower, so it is convenient to provide a reinforcement at the upper edges of the side walls along the open upper part.
[0017]
[0018] This top reinforcement can be provided by providing the box with top flaps that extend from the top edges of the side walls and folding and gluing these flaps against an interior or exterior surface of the side walls in order to double the thickness of the material from the side walls along a strip adjacent to the open top of the box.
[0019]
[0020] Document ES 2660059 A1 discloses a box-forming machine comprising a support structure, a folded box magazine configured to house a plurality of folded and stacked boxes vertically, a forming station configured around a vertical axis and which includes an operational space dimensioned to house a box during its formation, an openable deployment device to hold a box from the folded box warehouse and deploy it to a rectangular configuration and place it in an intermediate station, and a translation device operable to move the box in the rectangular configuration from the intermediate station to the operational space of the forming station.
[0021]
[0022] The machine described in the cited document ES 2660059 A1 further has a bottom shaping device having bottom flap benders configured to fold longitudinal and transverse bottom flaps of the box during translation thereof from the intermediate station to the operational space , and a clamp located at the forming station above the operational space, where the clamp is operable to move along a vertical axis aligned path between a position outside the operational space and a position within the operational space to press the transverse and longitudinal bottom flaps of the box, which have been previously glued, against the bottom flap benders.
[0023] A drawback of the machine described in the cited document ES 2660059 A1 is that it does not include an upper flap folding device that allows folding of upper flaps to provide the box with additional reinforcement along a strip of the side walls of the box adjacent to the open top.
[0024]
[0025] Another drawback of the machine described in the cited document ES 2660059 A1 is that the arrangement of the intermediate station and the configuration of the lower flap benders so that they fold the transverse and longitudinal lower flaps of the box during the translation of the box from the intermediate station to the operational space makes the floor space occupied by the machine very large and the machine is especially bulky.
[0026]

[0082]
[0083] Detailed description of some embodiment examples
[0084]
[0085] Referring firstly to Figs. 1, 2 and 3, reference sign 100 generally designates a box forming machine according to an embodiment of the present invention, comprising a support structure 23 incorporating a folded box store 1 and a forming station 5.
[0086]
[0087] The folded box store 1 is configured to house a plurality of boxes 50 folded and stacked vertically. The shaping station 5 is configured around a vertical axis Z and comprises an upper shaping device 6 supported on the support structure 23, a lower shaping device 24, and an operational space 28 located between the upper shaping device 6 and the lower shaping device 24. Operational space 28 is dimensioned to house a box 50 during shaping it in shaping station 5.
[0088]
[0089] Fig. 6 shows a corrugated cardboard die-cut sheet or the like corresponding to the flat development of a box 50 capable of being formed with a machine according to the present invention. The die-cut sheet comprises split lines defining a plurality of panels corresponding to side walls 51 and lower and upper flaps 52, 53, 54.
[0090]
[0091] More particularly, the panels of the die-cut plate include eight side walls 51 connected consecutively by their side edges forming a strip. A longitudinal bottom flap 52 and a transverse bottom flap 53 extend from alternate side wall bottom edges 51, and from upper edges of the side walls 51 extend upper flaps 54.
[0092]
[0093] From a side edge of one of the side walls 51 located at one end of the strip extends a connecting flange 55 intended to be attached, for example by adhesive, to the side edge of the other of the side walls 51 located at the other end of the strip so that the die plate strip constitutes a closed ring of octagonal configuration, as shown in Fig. 7. Optionally, the closed ring can go through a rectangular configuration before adopting the octagonal configuration.
[0094]
[0095] The closed ring of each box 50, when arranged in the folded position in the folded box magazine 1, is flattened so that one half of the panels are superimposed on the other half of the panels. Since in the example shown the panels corresponding to the side walls 51 have different widths, the vertical slit lines defining one half of the panels do not coincide with the vertical slit lines defining the other half of the panels.
[0096]
[0097] For the formation of the box 50 from the closed ring shown in Fig. 7 it is necessary to apply glue on some external surfaces of the longitudinal bottom flaps 52 or of the transverse bottom flaps 53, consecutively folding the longitudinal and transverse bottom flaps 52, 53 and pressing them against each other to join them together to form a totally or partially closed bottom, as well as applying glue on inner surfaces of the upper flaps 54, folding the upper flaps 54 inwards and pressing them against inner surfaces of the side walls 51 to form a reinforcement along a strip of side walls 51 adjacent to an open top of box 50.
[0098]
[0099] The machine includes a deployment and translation device 27 configured to hold a box 50 of the folded box warehouse 1, unfold it and place it in a rectangular configuration in the operational space 28 of the forming station 5.
[0100]
[0101] The deployment and translation device 27 comprises a gripping member 2 provided with suction cups 3 supported by an arm 15 connected to a carriage 16 driven by an actuator, such as a motor 29 in cooperation with a movement transmission mechanism, to move in a transverse X direction along a guide transverse 4 between a position adjacent to the folded box warehouse 1 and a position adjacent to one side of the operating space 28 opposite the folded box warehouse 1. The arm 15 is extendable in a longitudinal direction Y to move the finished box 50 from the space Operational 28 from forming station 5 to an exit conveyor 17.
[0102]
[0103] The upper shaping device 6 is centered with respect to the vertical axis Z and has a frame 25 coupled to a first upper vertical guide 7. The frame 25 is driven by an actuator, such as motor 30 in cooperation with a motion transmission mechanism , so that it can move in a path aligned with the vertical axis Z between a position outside of operational space 28 and a position within operational space 28.
[0104]
[0105] The frame 25 has installed side gripping walls 11 arranged to exert back pressure on interior surfaces of the side walls 51 of the box 50 during the shaping of the box 50 in the shaping station 5. The side gripping walls 11 are expandable and are configured and actuated to expand box 50 from within from rectangular configuration to octagonal configuration by expansive movement of the side sucker walls 11. Fig. 1 shows a box 50 arranged in the octagonal configuration in the operational space 28 of the station conformation 5.
[0106]
[0107] As shown in Fig. 4, in the illustrated embodiment, the side end walls 11 of the upper shaping device 6 are grouped into two subsets 11a, 11b coupled to longitudinal expansion guides 31 and actuators, such as for example pneumatic cylinders. 32, are connected to each of the two subassemblies 11a, 11b and to the frame 25, so that an activation of the pneumatic cylinders 32 moves the two subassemblies 11a, 11b of lateral end walls 11 with respect to the frame 25 in opposite directions in the longitudinal direction Y. The lateral end walls 11 are configured to expand the box 50 from the rectangular configuration to the octagonal configuration as a result of the expansive movement of the lateral end walls 11. Alternatively, the expansion guides 31 could be transverse to effect the movements of two subsets 11a, 11b of side end walls 11 with respect to the frame 25 in opposite directions in the transverse X direction.
[0108] Fig. 5 shows an alternative embodiment in which the side end walls 11 of the upper shaping device 6 are grouped into four subsets 11a, 11b, 11c, 11d coupled to oblique expansion guides 33 inclined both with respect to the transverse direction X as regards the longitudinal direction Y. The four subsets 11a, 11b, 11c, 11 d are actuated by respective actuators, for example by pneumatic cylinders 32, so that they are movable with respect to the frame 25 in opposite directions in some directions obliques with components in the combined transverse and longitudinal X, Y directions. Other alternative mechanisms for moving the four sub-assemblies 11a, 11b, 11c, 11d of side end walls 11 in the aforementioned oblique directions will readily occur to one skilled in the art.
[0109]
[0110] At a lower end of the sub-assemblies 11a, 11b of lateral nose walls 11, a clamp 8 (Fig. 3) is fixed, which moves together with the frame 25 in the direction of the vertical axis Z between a position outside the operational space 28 and a position within the operating space 28. In an alternative embodiment, not shown, the clamp 8 is operable to move independently of the frame 25, for example by actuation of an actuator along a vertical guide device.
[0111]
[0112] As shown in Figs. 1, 2 and 3 On an upper part of the sub-assemblies 11a, 11b of the side suction walls 11 an upper gluing device is installed that includes a plurality of upper glue application nozzles 12 arranged to apply glue on inner surfaces of the upper flaps 54 of box 50 during movement of frame 25 relative to box 50. The top glue application nozzles 12 are grouped into two subgroups and each subgroup of top glue application nozzles 12 is installed in one of the two subsets 11a , 11b of side dolly walls 11.
[0113]
[0114] In the embodiment shown in Fig. 5, the top glue application nozzles 12 are grouped into four subgroups and each subgroup of top glue application nozzles 12 is installed in one of the four subsets 11a, 11b, 11c, 11d of side dolly walls 11.
[0115]
[0116] The upper shaping device 6 further comprises an upper bender bracket 18 which is annular in shape and which is arranged around the path of the frame 25 and of the sub-assemblies 11a, 11b of the end walls. side 11. The upper bender bracket 18 is coupled to a second upper vertical guide 13 and is driven by an actuator, such as a motor 26 in cooperation with a motion transmission mechanism, to move along a path aligned with the vertical axis Z between a position outside of operational space 28 and a position within operational space 28.
[0117]
[0118] A plurality of upper flap benders 14 are installed in the upper bender bracket 18, which are mounted in such a way that they can pivot about respective horizontal axes parallel to the side sucker walls 11 under the actuation of actuators, such as pneumatic cylinders (not shown), for bending the previously glued upper flaps 54 of the box 50 and pressing them against the inner surfaces of the side walls 51 of the box 50. As an example, the upper flap benders 14 can be based on a mechanism such as that described in patent ES 2432097 B1, by the same applicant.
[0119]
[0120] With this arrangement, the upper bender bracket 18 is movable independently of the frame 25 and the side sucker walls 11 are movable along the vertical axis Z through the upper bender bracket 18 of annular configuration. In an alternative embodiment (not shown), the top bender bracket 18 is attached to the frame 25 of the top shaping device 6 and is arranged around the sub-assemblies of side sucker walls 11 so that it moves together with the frame 25.
[0121]
[0122] As Fig. 3 best shows, the lower shaping device 24 is located in the shaping station 5 below the upper shaping device 6 and the operating space 28, and centered with respect to the vertical axis Z. The shaping device Bottom 24 comprises a bottom gluing device and bottom flap benders 9, 10.
[0123]
[0124] The bottom gluing device includes a bottom nozzle holder 19 coupled to a bottom vertical guide 20 and actuated by an actuator 37 so that it can move along a path aligned with the vertical axis Z between a position outside of operating space 28 and a position within operational space 28, and a plurality of lower glue application nozzles 21 located in the lower nozzle holder 19 and arranged to apply glue on exterior surfaces of the longitudinal bottom flaps 52 of the box 50 during a movement of the lower nozzle support 19 relative to the box 50.
[0125]
[0126] The bottom flap benders 9, 10 are installed in a bottom bender bracket 34, which is attached to the support structure 23. Each of the bottom flap benders 9, 10 is rotatably connected to the bottom bender bracket 34 by a horizontal pivot shaft 35, and an actuator, such as a pneumatic cylinder 36, is connected to each of the lower flap benders 9, 10 and to the lower bender bracket 34, so that an actuation of the cylinders Tires 36 pivots the bottom flap benders 9, 10 from a vertical idle position or tilted below the pivot shafts 35 (not shown) to a horizontal active position (shown in Fig. 3) to fold the transverse bottom flaps and longitudinal 52, 53 of the box 50 and pressing them against the clamp 8 of the upper shaping device 6 in order to form the partially closed bottom of the box 50 .
[0127]
[0128] In the embodiment shown in the Figures, the bottom gluing device is configured to apply glue on the outer surfaces of the longitudinal bottom flaps 52 of the box 50 and the pneumatic cylinders 36 of the bottom flap benders 9, 10 are controlled to bend first the longitudinal bottom flaps 52 and then the transverse bottom flaps 53.
[0129]
[0130] In an alternate embodiment (not shown) the bottom gluing device is configured to apply glue to outer surfaces of the transverse bottom flaps 53 and the pneumatic cylinders 36 of the bottom flap benders 9, 10 are controlled to first fold the bottom flaps transverse 53 and then the longitudinal bottom flaps 52.
[0131]
