Description

[Technical Field]

[0001] The present invention relates generally to the technical field of equipment for producing packaging boxes, and more particularly to an assembly for automatically folding corners of boxes.

[0002] The present invention also relates to a method for automatically folding in the aforementioned corners. [Background technology]

[0003] The use of boxes obtained by starting with modules or sheets made of flat, relatively rigid, layered material, such as paper or cardboard, which are suitably shaped and folded along crease lines, has long been known in the packaging industry.

[0004] In particular, the sheet has a generally rectangular shape in plan view, allowing for the formation of a bottom wall, a top wall, and a plurality of side walls along respective longitudinal and transverse fold lines.

[0005] The side walls are folded together to form a box, which is closed at the top by a top wall joined to one of the side walls.

[0006] An example of this type of box is represented by the FEFCO 410 standard, in which at least two walls of the box are provided with at least one wing designed to fold in to form respective corners of the box.

[0007] Generally, boxes of this type are obtained by using a machine equipped with means for feeding corrugated cardboard sheets and means for cutting, scoring and folding the sheets along the longitudinal and transverse directions, respectively.

[0008] Furthermore, the corners of the box are formed using a pair of pneumatic devices designed to fold in each wall and each wing of the box, and a pressing device adapted to apply pressure to the contact surfaces between the walls and the wings to bond them together.

[0009] A first drawback of such known machines is the insufficient effectiveness of the pneumatic and pressing devices, which leads to longer production times.

[0010] Furthermore, such machines are unable to provide adequate pressure distribution to the contact surfaces, as their effectiveness depends on the quality of the cardboard and crease lines used.

[0011] In an attempt to at least partially overcome these drawbacks, machines and assemblies have been developed for automatically folding corners of boxes, comprising devices for folding at least one wall and each wing.

[0012] U.S. Pat. No. 3,451,317 discloses a machine for producing boxes in which a creased sheet is conveyed by an advancing means to a processing station adapted to form the corners of the box.

[0013] The station comprises a pair of rollers suitable for simultaneously lifting the side walls of the box to position it at least partially vertical, and a lifting element suitable for simultaneously folding at least one wing portion of the bottom wall towards the vertical side wall.

[0014] The adhesive device then establishes each corner of the box by applying a suitable adhesive to the opposing surfaces to hold the vertical walls firmly in contact with the associated wings.

[0015] WO2012117339 discloses an assembly for forming corners of a box, provided with a pair of rotating elements adapted to rotate the side walls of the box vertically and to rotate the respective wings horizontally to place them in contact along a contact surface.

[0016] U.S. Pat. No. 3,196,761 discloses an assembly for automatically folding corners of boxes made of layered material, the assembly comprising one or more folding means for folding wings designed to form the corners of the box, and a motor system mechanism adapted to connect such folding means.

[0017] A drawback of such known solutions is that the corners of the boxes do not have a stable structure and tend to bend and deform over time, especially during the required moving and transport steps.

[0018] Furthermore, the rollers, lifting elements, and rolling elements described above do not provide adequate pressure distribution to the flaps to be folded as the box height varies.

[0019] The endless drawbacks of such solutions are the low efficiency and long production times, which are major disadvantages. [Prior art documents] [Patent documents]

S The second wing W2 is overlapped by a pair of side walls P L2 and perpendicular to the two wings W1 and W2, respectively, and the side wall P L1 and a third wing portion W3 that can be superimposed on the first wing portion W1.

[0042] In the example shown in FIG. 1, each corner C of the box B is connected to a side wall P L1 The first wing portion W1 is attached to the bottom wall P F The second wing W2 may be formed by overlapping the first wing W1 with the second wing W2.

[0043] As better shown in Figures 2 and 3, the assembly 1 can be set up at a forming and closing station 2 of an automatic machine 3. The automatic machine 3 starts from a continuous cardboard module and further comprises a cutting and creasing station, suitable for obtaining boxes B.

[0044] The machine 3 is provided with advancing means 4 for advancing the box B along a predetermined folding and forming path in the automatic machine 3 and assembly 1 for each corner C of the box B, which may speed up the production time of the box B.

[0045] In the embodiment shown in the figures, the machine 3 comprises four assemblies 1 according to the invention. The two assemblies 1 shown in Figures 2 and 3 are arranged on the side wall P L1 The first wing portion W1 is attached to the bottom wall P F On the other hand, two other assemblies 1 (not shown) arranged in a mirror image with respect to these two assemblies 1 are adapted to overlap the second wing portion W2 of the other side wall P L1 The first wing portion W1 is connected to the bottom wall P F The second wing W1 is adapted to overlap the other portion of the second wing W2.

[0046] Obviously, the other four assemblies 1 are attached to the top wall P of the box B, which is not shown. S It can be provided for the other corner C in the

[0047] In a preferred embodiment of the present invention, the assembly 1 comprises a first folding means 5, which folds the side wall P of the box B along the first fold edge T1. L1 , P L2 The first wing portion W1 in at least one of the above is folded in.

[0048] The first folding means 5 comprises a rotation device 6 for at least one leaf 7 that is substantially horizontal. The leaf 7 is rotated by the side wall P L1 , P L2 The first wing W1 of the box B is folded toward the closed compartment of the box B by the side wall P L1 , P L2The first wing W1 is preferably adapted to interact with the first wing W1 by contacting it.

[0049] Advantageously, as better shown in FIGS. 4 and 5, the side wall P L1 , P L2 To position the first wing W1 substantially perpendicular to the side wall P L1 , P L2 The rotation device 6 positions the leaves 7 so that they form a predetermined angle of at least 90° with respect to the axis of rotation.

[0050] Preferably, at least one leaf 7 may be made of a harmonic metal material.

[0051] As better shown in Figures 8 to 10, the rotation device 6 comprises a shaft 8 rotatable about a substantially vertical axis Y, to which the leaves 7 are welded or fixed.

[0052] The shaft 8 is driven in rotation by automatic rotation means 9, of a type selected from the group consisting of a compressed air cylinder or a camshaft with a suitably configured cam.

[0053] In the embodiment shown in the figures, the automatic rotation means 9 are of the type of compressed air cylinders, which are adapted to push the propelling member 10. The propelling member 10 comprises a first contact portion 11 and a second contact portion 12 suitable for interacting with the first end 8' of the shaft 8.

[0054] The first end 8' may comprise a plate-like element 13. The plate-like element 13 has a third contact portion 14 and a fourth contact portion 15 that are substantially perpendicular to the shaft 8 and designed to interact with the first contact portion 11 and the second contact portion 12, respectively, of the propulsion member 10, thereby causing the shaft 8 and the at least one leaf 7 to rotate.

[0055] In other words, the first contact portion 11 of the propulsion member 10 interacts with the third contact portion 14 of the plate-like element 13 to fold the first wing portion W1 towards the closed compartment of the box B, while the second contact portion 12 of the propulsion member 10 interacts with the fourth contact portion 15 of the plate-like element 13 to position the leaf 7 in its initial position and distal from the first wing portion W1.

[0056] Advantageously, at least one abutment device 16 may be provided, as shown in Figures 5 and 8, which is L1 , P L2 and to enhance the formation of corner C of box B along first fold edge T1.

[0057] Furthermore, the second folding means 17 is F or upper wall P S The second wing portion W2 of at least one of the first and second fold edges T2 is provided for folding in along the second fold edge T2.

[0058] The second folding means 17 comprises a pushing device 18 selected from the group consisting of a wheel or roller, a shaped sheet, a bristle brush, or similar contact means.

[0059] In the embodiment shown in the figures, as better shown in FIGS. 6 and 7, the pushing device 18 is of the roller type, which is moved vertically and pushes the bottom wall P F or upper wall P S The second wing W2 is pressed against the bottom wall P F The second wing W2 is folded toward the interior compartment of the box B at a predetermined angle of at least 90° relative to the first wing W1 and positioned so that it contacts the first wing W1.

[0060] The pressing device 18 is pressed against a pair of plates 19, preferably made of harmonic material, thereby causing the plates 19 to always maintain contact with the second wing portion W2 when the second wing portion W2 is folded in.

[0061] Preferably, an applicator (not shown) is provided for applying adhesive to at least one of the first wing portion W1 and the second wing portion W2 to enable them to adhere to each other.

[0062] Advantageously, as will be further explained below, the assembly 1 comprises a mechanical kinematic mechanism 20 connecting the first folding means 5 and the second folding means 17 adapted to align and simultaneously fold the first wing portion W1 and the second wing portion W2, and thus the corner portion C of the box B.

[0063] As better shown in Figures 8 to 12, the assembly 1 has a substantially horizontal first guide portion 21 and a substantially vertical second guide portion 22, which are suitable for guiding the first sliding portion 23 and the second sliding portion 24, respectively, which are connected to each other by a motor system mechanism 20, thereby facilitating the simultaneous operation of the first folding means 5 and the second folding means 17.

[0064] The first guide member 21 and the second guide member 22 may be selected from the group consisting of one or more raceways, a recirculating ball screw, a cylindrical drum cam, or similar means.

[0065] Additionally, the motor mechanism 20 may be of a type selected from the group consisting of a connecting rod crank, a swing flute, a pinion and rack, or a belt mechanism.

[0066] In the embodiment shown in the figures, the first guide part 21 and the second guide part 22 are of the track type, and the kinematic mechanism 20 is an articulated mechanism comprising an arm 25 having two ends 25', 25'' hinged to the first sliding part 23 and the second sliding part 24, respectively.

[0067] The kinematic mechanism 20 further comprises a connecting rod 26 having two ends 26', 26'', each hinged to the second slide 24 and to an outer end 27' of a crank 27 having an inner end 27'' driven in rotation by motor means 28 of known type.

[0068] In use, the rotational movement of the crank 27 is converted into a vertical reciprocating movement of the second slide 24, which, via the arm 25, causes the first slide 23 to reciprocate horizontally.

[0069] As shown in the figure, the rotating device 6 is pressed against the first sliding portion 23, moving at least one leaf 7 along the first guide portion 21 and away from the first wing portion W1, thereby enabling the pushing device 18 to fold the second wing portion W2 onto the first wing portion W1 without overlapping the leaf.

[0070] As a result, the mechanical movement system mechanism 20 is suitable for cyclically and sequentially moving the first sliding part 23 and the second sliding part 24, respectively, between the first end position A1 and the second end position A2, and between the first end stroke position B1 and the second end stroke position B2.

[0071] The assembly 1 comprises a central control unit, not shown, which is adapted to coordinate the movements of the abutment device 16, the automatic rotation means 9 and the motor means .

[0072] In other words, when the second slide 24 is in the first end stroke position B1, the first slide 23 is in the first end position A1, and the central control unit is activated to operate the components of the assembly 1, which are moved in the following order: - actuating the abutment device 16, as shown in Figure 8; 9 and 10, the automatic rotation means 9 presses the first contact portion 11 of the propelling member 10, which interacts with the third contact portion 14 of the plate-like element 13, causing the shaft 8 and the leaf 7 to rotate towards the closed compartment of the box B and against the side wall P L1 , P L2 fold in the first wing portion W1 of one of the wings; 11 and 12, the motor means 28 move the second sliding part 24 vertically towards the second end stroke position B2, and via the motor system mechanism 20, they move the first sliding part 23 horizontally towards the second end position A2, thereby driving the first folding means 5 together with the first sliding part 23; As shown in Figures 11 to 13, the pushing device 18 is F or upper wall P S interacting with the second wing portion W2 of the box B, thereby folding the second wing portion W2 towards the closed compartment of the box B; As shown in Figures 12 and 13, the second contact portion 12 of the propulsion member 10 interacts with the fourth contact portion 15 of the plate-like element 13, causing the shaft 8 and the leaf 7 to rotate in the opposite direction and distal to the folded first wing portion W1.

[0073] At this point, the corner C of box B is fully folded and the advancing means 4 of machine 3 moves box B out of forming station 2 so as to fold the corner C of the following box B.

[0074] In an alternative embodiment, not shown, the automatic rotation means 9 is of the camshaft type, suitably configured and driven by a mechanical kinematic mechanism 20 .

[0075] It is clear that the interconnection between the first folding means 5 and the second folding means 17 via the motor system mechanism 20 facilitates the accuracy of registration between the first wing portion W1 and the second wing portion W2, as well as the alignment of the folding means 5, 17.

[0076] In a preferred embodiment of the present invention, as shown in the figures, the first folding means 5 comprises two leaves 7', 7" spaced apart from each other along the shaft 8. The leaf 7' is adjacent to the second wing W2 and is shorter than the other leaf 7", with the leaf 7" being in a distal position relative to the second wing W2.

[0077] Thus, when the pushing device 18 is actuated along the surface of the second wing portion W2 to slide the first sliding portion 13 towards the second end position A2, the leaf 7' moves away from the corner C of the box, while the other leaf 7'' can remain in contact with the first wing portion W1, as better shown in Figures 6 and 11.

[0078] It is clear that assembly 1 folds in corners C of box B, making it possible to provide an appropriate pressure distribution regardless of the height of box B, ensuring the creation of a box with a particularly stable and durable structure.

[0079] According to another particular aspect of the present invention, there is provided a method for automatically folding corners C of a box B using an assembly 1, the method comprising: The abutment device 16 is attached to the side wall P of the box B. L1 , P L2 and actuating at least one of the The side wall P of the box B L1 , P L2 activating the first folding means 5 along the first fold edge T1 for the first wing W1 in at least one of the connecting the first folding means 5 to the second folding means 17 via a mechanical movement system 20 so as to align and fold the corners C of the box B; operating the first sliding portion 23 along the first guiding portion 21 to move the first folding means 5 away from the first wing portion W1; The second sliding portion 24 is operated along the second guide portion 22, and the second folding means 17 is moved along the second fold edge T2 to the bottom wall P of the box B. F or upper wall PS activating for at least one second wing portion W2 of the Folding the second wing portion W2 onto the first wing portion W1; Includes:

[0080] With reference to the above, it is clear that the assembly and method for automatically folding corners of boxes according to the invention have achieved their predetermined objectives, in particular that they make it possible to provide an appropriate pressure distribution regardless of the height of the box, so that the box is particularly stable and durable.
