Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing corrugated sheets starting from a reel of cardboard, and to the field of manufacturing or packaging boxes made of corrugated cardboard for packing articles, i.e., the field of packing one or more articles in boxes using packing cardboard, or packing one or more articles. The present invention relates to machines for obtaining strips or sheets of corrugated cardboard for packing or packing articles in boxes using corrugated cardboard, and to machinery for packing or packing articles, as well as related operating methods. More specifically, the present invention relates to a machine for packing or packing articles and a machine for supplying corrugated cardboard to the machine for packing or packing articles. This corrugated cardboard is generally a single-layer corrugated cardboard sheet, but in some cases it is also a single-sided corrugated cardboard sheet.

Background Art

[0002] In the present invention, standard corrugated cardboard, also known as single-layer corrugated cardboard, generally means cardboard with an outer layer of two smooth cardboard sheets and a corrugated layer of cardboard inserted between them. On the other hand, the term single-sided corrugated cardboard means cardboard having two layers: namely, a corrugated layer of cardboard and a generally smooth cardboard layer. As an example, FIG. 1 shows the corrugated layer of cardboard. FIG. 2 shows a smooth cardboard layer and a corrugated layer of cardboard with a top covered with an adhesive facing the smooth cardboard layer. FIG. 3 shows a corrugated layer of cardboard inserted between two layers of smooth cardboard with a top covered with an adhesive such as, for example, a vinyl-based adhesive and / or a hot-melt adhesive.

[0003] It is known that single-layer or single-sided corrugated cardboard can be obtained by starting from a reel of smooth cardboard in a system or line extending horizontally for tens of meters. Solutions that utilize the unfolding of cardboard strips, with the aim of ensuring production speed and good manufacturing quality, are suitable for continuous production and / or large batch production, but due to their dimensions and cost, they are difficult to integrate into industrial equipment upstream of one or more machines for packaging articles. Examples of similar devices are described in European Patent No. 0146441 and European Patent Application Publication No. 2460651.

[0004] French Patent No. 362835 describes a binding machine for obtaining single-layer corrugated cardboard, starting from a first reel of single-sided corrugated cardboard and a second reel of smooth cardboard.

[0005] A machine described in British Patent Application Publication No. 132725 is also known, which is not arranged in a line and starts with first and second reels of smooth cardboard to produce a reel of single-sided corrugated cardboard; this reel is positioned high and the cardboard passes through corrugated rollers with adhesive applied to the top before being bonded with the smooth cardboard coming from the other reels.

[0006] Cardboard products obtained using the machines mentioned and other known machines are transported to the apparatus in the form of sheets, reels, fanfolds, blanks, or flat boxes to be formed. In this apparatus, machinery for boxing the articles is set up and arranged inside one or more warehouses, and the articles are then assembled to form boxes or packaging.

[0007] The need to reduce box size and / or cardboard consumption has led to the introduction of machinery for forming boxes, where each cardboard box or packaging is based on the articles that must be enclosed or directly wrapped using packing cardboard.

[0008] European Patent Application Publication No. 2890554 describes a method and machinery for packaging articles, beginning with continuous cardboard strips. The cardboard strips are stored on suitable reels or in continuous sheets of corrugated cardboard folded in an accordion manner, known as a fanfold, as mentioned above. The cardboard strips, unwound from the reels or drawn from the fanfold, are cut and slit according to the dimensions of the articles.

[0009] European Patent Application Publication No. 3867053 describes a machine that can be used upstream of machinery for packaging articles, which obtains cardboard strips by joining cardboard sheets together in a continuous manner.

[0010] European Patent Publication No. 3947167, European Patent Publication No. 3464074, and European Patent Publication No. 4117995 describe machinery and methods for boxing articles, starting from strips or fanfolds.

[0011] European Patent Application Publication No. 4157726 describes a packaging machine that wraps a strip around an article to form a package containing the article.

[0012] European Patent Application Publication No. 3947166 relates to a method, machine, and machine equipment for obtaining a box starting from a die-cut blank of cardboard, and for boxing multiple articles.

[0013] International Publication No. 2023 / 002396 describes machinery and methods for forming boxes to be adapted to their respective contents.

[0014] Managing reels made of single-layer corrugated cardboard, such as fanfold or formed boxes, is particularly economically challenging and / or requires careful preparation and / or continuous supply, and / or results in significant space occupied both during storage and transport due to the volume of empty space in the corrugated cardboard.

[0015] Furthermore, in the case of fanfolds, the resulting packaging may have several undesirable folds that coincide with the original folds of the "bellows"; such folds are aesthetically inferior and / or weaken the packaging itself in terms of providing inferior protection to the contents. In the case of forming boxes, the dimensions of the base can only be customized through another operational step, starting with the selection of the box to be formed in the warehouse.

[0016] The machinery for boxing or packaging goods using corrugated cardboard, described in International Publication No. 2014 / 119439, begins by creating blanks from multiple strips coming from each reel, and moves these blanks as they are being formed on a conveying means equipped with a roller conveyor.

[0017] International Publication 2014 / 119439, like U.S. Patent Application Publication 2018 / 117870, describes the use of pressure rollers to join overlapping corrugated cardboard layers together. However, these two documents do not clearly explain how high-quality corrugated cardboard can be obtained using appropriately sized machinery and continuous production stoppages, which are not provided in the case of the machinery described in European Patent No. 0146441 and European Patent Application Publication No. 2460651, and are difficult to manage. Therefore, the need for machinery with these features is clear. This is especially true because the applicant is unaware that machinery such as that described in International Publication 2014 / 119439 is available on the market.

[Figure 25] This figure shows another embodiment of the machinery and equipment for boxing or packaging articles using corrugated cardboard according to the present invention. [Modes for carrying out the invention]

[0033] Referring to the attached diagram, reference number 10 indicates a machine for supplying corrugated cardboard to a machine (100) for boxing or packaging goods (P).

[0034] These reference numbers are included to facilitate understanding of the invention, but are not intended to limit the scope of the invention.

[0035] Embodiments of machine (10) are: - A first reel unwinder (1) for unwinding a first strip (N1) from a first reel (B1) of cardboard; - A second reel unwinder (2) for unwinding a second strip (N2) from a second cardboard reel (B2); - Adhesive dispenser (4) for applying adhesive (A) to one side of a cardboard strip; - A pressing machine (5) equipped with a first pressing belt (51) that presses the strip and pulls the strip out in the pulling direction (T); -A first path (11) in the first strip (N1) leading from the first unwinder (1) to the presser (5); - The second path (12) in the second strip (N2) leading from the second unwinder (2) to the press (5); - A control unit (10a) that controls the pressing machine (5), It is equipped with.

[0036] The path between the first path (11) and the second path (12) crosses the adhesive dispenser (4) so ​​that the adhesive dispenser (4) applies adhesive (A) to the first strip (N1) or the second strip (N2).

[0037] The first path (11) and the second path (12) are joined in front of or in the press (5) so that the adhesive (A) is inserted between the first strip (N1) and the second strip (N2).

[0038] The pressing machine (5) is equipped with a second pressing belt (52) above a first pressing belt (51), or a first pressing roller (53) and a second pressing roller (54) positioned above the first pressing belt (51) and spaced apart from each other in the pulling direction (T). Thereafter, the first pressing belt (51) and the second pressing belt (52) press against each other to pull out the first strip (N1) and the second strip (N2) together in the pulling direction (T) to form corrugated cardboard. Alternatively, the first pressing belt (51) and the first pressing roller (53), and the first pressing belt (51) and the second pressing roller (54) press against each other to pull out the first strip (N1) and the second strip (N2) together in the pulling direction (T) to form corrugated cardboard.

[0039] The control unit (10a) is configured to receive a continuous value which is the desired length of the corrugated cardboard whenever a desired length of corrugated cardboard is supplied from the presser (5) at the outlet, and to stop and restart the first presser belt (51) and the second presser belt (52), or to stop and restart the first presser belt (51), the first presser roller (53), and the second presser roller (54).

[0040] The machine (10) described above can make corrugated cardboard, i.e., corrugated cardboard strips and / or corrugated cardboard sheets, and facilitates the provision of a machine for boxing or packaging articles (P) using corrugated cardboard, as required and necessary.

[0041] For example, the machine (10) makes it possible to continuously produce three or more corrugated cardboard sheets (F), each having a different length (L) from the preceding and succeeding one.

[0042] The stopping and restarting between the first corrugated cardboard sheet (F) and the second corrugated cardboard sheet (F) allows for cutting the corrugated cardboard sheet (F) from a non-moving corrugated cardboard strip. More preferably, cutting is possible by positioning the press (5) horizontally or slightly inclined, i.e., without a downstream storage path that could negatively affect the quality of the product. Furthermore, this allows for consideration of time requirements imposed downstream from a machine (100) for boxing or packaging articles (P), such as in the machinery (1000) of the present invention.

[0043] In the embodiment shown in Figure 17, the pressing machine (5) is capable of drawing out adjacent strips at the same speed by pressure determined by the distance between the first pressing belt (51) and the second pressing belt (52), which are moved by their respective rollers. This pressure also allows for the equalization of layer formation in order to obtain high-quality corrugated cardboard.

[0044] In the embodiments shown in Figures 4 and 9, the second pressure belt (52) does not press or pull together with the first pressure belt (51) along its entire length, but presses or pulls together only the first portion (t1) and the second portion (t2).

[0045] In the embodiment shown in Figure 10, the upper pressure belt, i.e., the second pressure belt (52), is replaced by a first pressure roller (53) and a second pressure roller (53) spaced apart from each other in the withdrawal direction (T) to achieve the same effects as those in Figures 4 and 9.

[0046] As will become clear from the following description, the embodiments in Figures 4, 9, and 10 facilitate the placement of the heater (50) in a particularly efficient and effective manner.

[0047] The presence of the pressing machine (5) described above, and the control unit (10a) that controls the pressing machine (5) in a manner that stops and restarts production, enables cutting of the formed corrugated cardboard, which can be done in the same machine (10) or in a downstream machine, thereby obtaining corrugated cardboard sheets (F) of the desired length (L). Furthermore, the above configuration makes it possible to maintain a good quality level of corrugated cardboard compared to that obtained using the machine described in International Publication No. 2014 / 119439 or U.S. Patent Application Publication No. 2018 / 117870.

[0048] More specifically, as shown in Figure 16 as an example, the press (5) may comprise a first press belt (51) and a second press belt (52), which are spaced apart and facing each other to press and move a first strip (N1), a second strip (N2), and a third strip (N3). Generally, the first press belt (51) and the second press belt (52) engage with their respective rollers, at least one of which is powered or rotated by a motor, generally an electric motor. Control of each powered roller and / or motor allows the first press belt (51) and the second press belt (52) to be stopped and restarted, thereby enabling the production of corrugated cardboard to be stopped and restarted, as well as enabling the advance of the corrugated cardboard to finally cut the corrugated cardboard sheet (F).

[0049] Figure 11 shows the operation of another embodiment, which can also be used in Figures 4, 9, 13, and 17. It is known how these operations enable the same speed of withdrawal between the first pressure belt (51) and the second pressure belt (52), or between the first pressure belt (51), the first pressure roller (53), and the second pressure roller (54).

[0050] Figures 16 and 17, and Figures 12 and 13 show the first strip (N1), the second strip (N2), and the third strip (N3), representing the first route (11), the second route (12), and the third route (13), respectively. The reference numbers are substantially interchangeable.

[0051] As shown in Figures 8 and 9, the second pressing belt (52) can follow the path while maintaining pressing and pulling in the first portion (t1) and the second portion (t2), which allows the heater (50) to be introduced.

[0052] The same effect can be achieved using a first pressure roller (53) and a second pressure roller (54) spaced apart from each other in the pull-out direction (T), as shown in Figure 10 as an example. Figure 10 shows the adjustment of the distance between the first pressure belt (51) and the first and second pressure rollers (53 and 54); the rollers are hinged to a frame and set to rotate by actuators. In the example of Figure 10, there are two actuators for each roller.

[0053] The machine (10) preferably: -A heater (50) between the first strip (N1) and the second strip (N2), positioned above the first pressure belt (51) and directly facing the first pressure belt (51), such that it does not come into contact with the first pressure belt (51), i.e., does not come into contact with the first strip (N1) in the example of Figure 4, and / or preferably - A moving device (55) moves the heater (50) away from the first pressure belt (51) or perpendicularly toward the first pressure belt (51). It is equipped with.

[0054] While heating means are known to be used with known types of presses, the configuration of the heater (50) as taught herein, located above the first press belt (51), between the first press belt (51) and the second press belt (52), or between the first press roller (53) and the second press roller (54), brings many benefits to the machine (10).

[0055] Heating the space between the pressurized first portion (t1) and second portion (t2), either by using a second pressure belt (52) or by using a first pressure belt (53) and a second pressure roller (53), improves the quality of the corrugated cardboard produced downstream of the stopping and restarting of the presser (5), for example, by enabling wider distribution of adhesive (A).

[0056] Especially in the case of vinyl-based adhesives, faster drying of adhesive (A) allows for greater production speed and / or smaller dimensions.

[0057] The adhesive properties of adhesive (A) can be reactivated, particularly when using an adhesive known as a heat-soluble adhesive (A). Specifically, due to the above configuration, by stopping the manufacturing process, the adhesive properties can be reactivated in the region where adhesive (A) has dried without the first strip (N1) and the second strip (N2) coming into contact with each other.

[0058] For these advantages, there are corresponding disadvantages: overheating of the first strip (N1) and the second strip (N2) when stopped, as well as overheating of the components of the machine (10). In detail, it is very difficult to completely block the heat flow, which carries the risk of deterioration or damage to the corrugated cardboard at the exit. Therefore, it is preferable to provide a moving device (55) that reduces or eliminates the aforementioned negative effects by moving the heater (50) away from the first strip (N1) and the second strip (N2).

[0059] Preferably, the control unit (10a) is configured to control the mobile device (55) and to operate the mobile device (55) between stopping and restarting.

[0060] According to the second configuration, the control unit (10a) distinguishes between a temporary stop that does not require the heater (50) to move and a stop that does require the heater to move. For example, the control unit (10a) can be configured using a maximum waiting time. If the maximum waiting time is exceeded or is expected to be exceeded, the control unit (10a) decides to move the heater (50) away and then move it closer before resuming the drawer.

[0061] In another configuration, the control unit (10a) can command the movement of the heater (50) each time. For example, if there is a machine for boxing or packaging goods (P) that obtains a box every 3 seconds, downstream of it, within this time interval, pulling out, separating, moving, and possibly cutting with a cutter (6) may be performed.

[0062] The choice of configuration also depends on the type of corrugated cardboard being processed, the type of adhesive used, and the operating temperature.

[0063] As shown in the embodiments of Figures 4, 9, and 10, the second pressure belt (52) preferably cooperates with the first pressure belt (51) for the first portion (t1) and the second portion (t2) which are separated from each other in the withdrawal direction (T), and the heater (50) is located between the first portion (t1) and the second portion (t2) or between the first pressure roller (53) and the second pressure roller (54) so ​​as to equally determine the two separated portions.

[0064] The resulting prototype demonstrates how these components improved the quality of the manufactured corrugated cardboard.

[0065] The heater (50) preferably comprises a plurality of heating strips (50a), as shown in example in Figure 8. The heating strips (50a) are preferably perforated.

[0066] Figures 7 to 9 show examples of how the moving device (55) may be constructed according to several forms. In a preferred embodiment, the moving device (55) includes a bridge above the presser, which is fixed to a frame and supports one or more actuators, two linear actuators in the case of Figures 7 and 8. The ends of the two linear actuators are connected to the heater (50) in order to move the heater (50). In another embodiment, as shown as an example in Figure 9, it is possible to utilize the vertical movement of a second presser belt (52) which can be used to determine the distance to the first presser belt (51). For example, Figure 7 shows three of four actuators which lift the second presser belt (52) relative to the first presser belt (51). By fixing the heater (50) to the frame of the second presser belt (52), it is possible to obtain the movement shown in Figure 9 and, of course, the return to the proximity position.

[0067] The movement of the second pressing belt (52) with the heater (50) is made possible by the presence of a second pressing machine visible on the right in Figure 9, which limits the effect of separation between the first pressing belt (51) and the second pressing belt (52). The different movements performed in the embodiments of Figures 7 to 10 allow for a reduction in the length of the machine (10) compared to the embodiment of Figure 9, eliminate the need for the presence of a second pressing machine, and enable the production of corrugated cardboard of better quality.

[0068] The machine (10) of the present invention allows the use of different types of adhesive dispensers (4). For example, the embodiment in Figure 4 shows the use of a sprayer (44) for applying a heat-soluble adhesive (A), the embodiment in Figure 13 shows the use of a coating roller (42), and the embodiment in Figure 20 shows the use of a nozzle (41) for spraying.

[0069] The machine (10) preferably includes a moving device (45), and further: - The adhesive dispenser (4) is equipped with an application roller (42) for applying adhesive (A); - The moving device (45) moves the application roller (42) between an operating position for applying adhesive (A) and a stationary position further away from the path of the strip to which the adhesive (A) is applied; - The control unit (10a) is configured to control the moving device (45) and to activate the moving device (45) to move the coating roller (42) to a stationary position if, for example, a stop timeout followed by a maximum waiting time has not been performed or should not be included; the maximum waiting time may be a few tenths of a second. The control unit (10a) may be configured to activate the moving device (45) at each stop. That is, one of the two above-described configurations of the moving device (55) may also be replicated in the moving device (45).

[0070] As has already been made clear, the adhesive dispenser (4) can be configured to dispense vinyl-based adhesive or heat-melt adhesive.

[0071] In the reference art, the use of roller-type adhesive dispensers is known, for example, as shown in Figures 12 and 16: the applicator roller (42) of the adhesive dispenser (4), or the applicator roller (82) of the second adhesive dispenser (8), which will be mentioned below, generally receive adhesive (A) from separate rollers immersed in a tank, preferably a vinyl-based adhesive.

[0072] When the adhesive dispenser (4) utilizes an adhesive application roller (42), higher quality corrugated cardboard can be obtained by applying adhesive (A) to the top of the second strip (N2). The same consideration can be applied to the second adhesive dispenser (8) when it is equipped with an application roller (82).

[0073] The machine (10) preferably includes a counter roller (43) on the applicator roller (42) of the adhesive dispenser (4). This facilitates the application of adhesive (A) to the top of the second strip (N2), as shown in Figure 19. Also visible in Figure 19 are the passages for the first strip (N1), the second strip (N2), and the third strip (N3) between two plates located downstream of the counter roller (43) and in front of the presser (5).

[0074] Replacing the roller-type adhesive dispenser with a spray-type adhesive dispenser (4) significantly simplifies the use of the machine (10) and the machinery (1000) because it provides easier management of the ready-to-use adhesive (A) that is collected in the tanks into which each of the other rollers is immersed, as is the case with the roller-type adhesive dispenser (4). Separately, the spray-type adhesive dispenser (4) collects substantially the amount of adhesive (A) in use from the tanks sequentially, reducing the risk of adhesive (A) degradation, clogging, or clumping. Similar considerations apply to the sprayer (44) that applies the heat-melt adhesive (A).

[0075] This is extremely important for the purposes of the present invention.

[0076] The adhesive dispenser (4) preferably includes a nozzle (41) for spraying adhesive (A), which is configured to spray adhesive (A) to one side of the cardboard strip.

[0077] The second adhesive dispenser (8) is also preferably of the spray type; the second adhesive dispenser (8) preferably comprises a nozzle (81) for spraying adhesive (A), which is configured to spray adhesive (A) onto one side of the cardboard strip.

[0078] The nozzle (41) of the adhesive dispenser (4), or the nozzle (81) of the second adhesive dispenser (8), can spray adhesive or other adhesives, such as heat-activated adhesives, without contacting the strip.

[0079] Figures 20–23 show a variation of machine (10) in Figure 17, using a spray adhesive dispenser. The spray adhesive dispenser can apply adhesive (A) to corrugated or smooth strips, and some tests have shown that better products are often obtained by applying adhesive (A) to smooth strips. In fact, when adhesive (A) is sprayed onto corrugated strips, some of the adhesive (A) spreads into the depressions between the peaks, creating deposits and / or a lack of uniformity, which do not occur when sprayed onto smooth strips.

[0080] As shown in Figure 23 as an example, the adhesive dispenser (4) preferably includes a nozzle (41), and the adhesive dispenser (4) traverses a first path (11), thereby distributing the adhesive (A) onto the first strip (N1), at least in its operating state.

[0081] As shown in Figure 21 as an example, the second adhesive dispenser (8) preferably includes a nozzle (81), and the third path (31) crosses the second adhesive dispenser (8), thereby dispensing the adhesive (A) onto the third strip (N3).

[0082] However, as shown in Figures 20 and 22: - The second adhesive dispenser (8) is equipped with a nozzle (81), and the second path (12) crosses the second adhesive dispenser (8), thereby the second adhesive dispenser (8) applies adhesive (A) to the second strip (N2), and / or - The adhesive dispenser (4) is equipped with a nozzle (41), and the first path crosses the adhesive dispenser (4), thereby the adhesive dispenser (4) applies adhesive (A) to the second strip (N2).

[0083] Figure 4 shows an example of a sprayer (44) for a heat-soluble adhesive (A).

[0084] Various types of adhesive dispensers (4) are interchangeable, although each has its own relative advantages and disadvantages, because some embodiments work well with one type of adhesive (A) rather than the other. For example, the variations in Figures 22 and 23 are also applicable to the embodiment in Figure 13.

[0085] This specification describes examples of two main versions of the machine (10): the first, which can be seen in particular in Figures 17 and 24, and the second, which can be seen in particular in Figures 4, 13, and 25. The first main version enables the production of single-layer corrugated cardboard starting from a reel of smooth cardboard, or enables production using single-sided corrugated cardboard when the first path (11) and adhesive dispenser (4) are stopped. The second main version, also known as a binder, enables the production of single-layer corrugated cardboard starting from a reel of smooth cardboard and a reel of single-sided corrugated cardboard, or enables production using single-sided corrugated cardboard starting from a reel of smooth cardboard and a reel of corrugated cardboard.

[0086] The main first version of machine (10) is: - A third reel unwinder (3) for unwinding a third strip (N3) from a third cardboard reel (B3); - A corrugation machine (7) for corrugating cardboard strips; - A second adhesive dispenser (8) for applying adhesive (A) to one side of a cardboard strip; -Means for pressing cardboard strips together (9); - The third path (13) of the third strip (N3) leading from the third unwinder (3) to the presser (5), To further prepare.

[0087] The second path (12) crosses the corrugating machine (7) so that the corrugating machine (7) processes the second cardboard strip (N2).

[0088] The path between the second path (12) and the third path (13) crosses the second adhesive dispenser (8) so that the second adhesive dispenser (8) applies adhesive (A) to the second strip (N2) or the third strip (N3).

[0089] The second path (12) and the third path (13) are joined before or on the pressing means (9) so that the adhesive (A) is inserted between the second strip (N2) and the third strip (N3).

[0090] In particular, the pressing machine (5) mentioned above is configured to press and pull out the first strip (N1), the second strip (N2), and the third strip (N3) together, thereby forming corrugated cardboard.

[0091] As illustrated in Figure 17, the machine (10) of the present invention can produce two of the most commonly required types of corrugated cardboard, and it can be used to produce another type of corrugated cardboard, namely single-layer corrugated cardboard and single-sided corrugated cardboard, which are commonly required in corrugated cardboard sheets (F). These can be produced in a system with one or more mechanical equipment for boxing or packaging articles using corrugated cardboard, as shown in Figures 24 and 25, near the following uses.

[0092] The corrugating machine (7) preferably comprises a first corrugating roller (71) and a suction-type second corrugating roller (72). The pressing means (9) comprises a roller (91) that cooperates with the second corrugating roller (72) and presses the second strip (N2) and the third strip (N3), thereby coupling with the second strip (N2) held by the suction of the second corrugating roller (72) at least initially.

[0093] In this way, a clearer and more precise bond can be obtained between the second strip (N2) and the third strip (N3).

[0094] One or both, and generally both, of the first corrugating roller (71) and the second corrugating roller (72) are heated. Failure to heat them may negatively affect not only the corrugation of the second strip (N2) but also the action of the adhesive (A).

[0095] The arrangement shown as an example in Figure 16 allows for limiting the length of the machine (10) and positioning the first reel (B1), the second reel (B2), and the third reel (B3) close to the floor, facilitating loading, unloading, and starting.

[0096] The first unwinder (1), the second unwinder (2), and the third unwinder (3) are preferably arranged adjacent to each other so that each reel (B1, B2, B3) occupies volume (V), and the corrugating machine (7), adhesive dispenser (4), and second adhesive dispenser (8) are arranged to ensure volume (V), that is, they are on the opposite side of volume (V) from the floor, as shown in the example in Figure 16.

[0097] Similar to Figure 4, Figure 12 shows another unwinder. It can act as a substitute for the second unwinder (2), taking into account that it generally consumes the second reel (B2) faster than the first reel (B1). In this case, it is preferable to place the first unwinder (1), the second unwinder (2), and the other unwinder adjacent to each other so that each reel (B1, B2) occupies the first volume, and the adhesive dispenser (4) and presser (5) are positioned to ensure the first volume, i.e., they are on the opposite side of the first volume (V) from the floor, as shown as an example in Figure 4.

[0098] As can be seen in the exemplary rectangle shown in Figure 16, the first cardboard reel (B1), the second cardboard reel (B2), and the third cardboard reel (B3) are generally made from smooth cardboard; these are smaller and less expensive than single-sided corrugated cardboard reels, assuming the same dispensing conditions.

[0099] The machine (10) of the present invention has a limited size and may occupy a space of 5 to 10 meters, generally about 6.5 meters, in the embodiment of Figure 17, for example. However, the machine (10) as shown in the embodiment of Figure 4 does not require a suction conveying belt (10b) between the presser (5) and the cutter (6), and can be made even more compact, up to or near the sum of the dimensions of the first reel (B1), the second reel (B2), and another reel, which substantially appears to occur in the case of Figure 4 or Figure 12. As in Figure 4, the presence of the heater (50) helps to reduce the length of the machine (10).

[0100] A machine (10) which may be a machine for supplying corrugated cardboard sheets (F) preferably includes a cutter (6) for cutting corrugated cardboard strips to obtain corrugated cardboard sheets (F), and a control unit (10a) stops the press (5) and controls the cutter (6) so that the cutter (6) cuts corrugated cardboard sheets (F) of a desired length (L).

[0101] Thus, the machine (10) for obtaining corrugated cardboard sheets (F), which are generally single-layer corrugated cardboard, facilitates the provision of machinery and equipment for boxing or packaging articles (P) using corrugated cardboard, as required and necessary.

[0102] The attached diagram shows a cutter (6) with a movable blade that follows a transverse path with respect to the withdrawal direction (T). However, other known types of cutters (6) can be used, for example, those with a blade that is movable vertically in cooperation with a counter blade.

[0103] Depending on the integration level of machine (10) associated with machine (100) downstream, the cutter (6) may not be present or may be integrated into the downstream machine, as shown below in relation to the machine equipment (1000).

[0104] Many variations of the control unit (10a) are known, and for example, the control unit (10a) may comprise a programmable logic controller, a single-board computer, or a more complex industrial control system.

[0105] The first unwinder (1) preferably includes a motor for unwinding a first reel (B1) of cardboard, and the control unit (10a) controls the motor of the first unwinder (1) based on a desired length value.

[0106] For example, Figure 16 shows the motor-driven roller (1a) of the first unwinder (1). Similarly, the second unwinder (2) and the third unwinder (3) can also be equipped with motors for unwinding the second reel (B2) and the third reel (B3) of cardboard, respectively. For example, Figure 16 shows the motor-driven roller (2a) of the second unwinder (2) and the motor-driven roller (3a) of the third unwinder (3).

[0107] The control unit (10a) also controls, preferably, the motor of the second unwinder (2), and optionally the motor of the third unwinder (3), based on a desired length value.

[0108] The present invention also relates to machinery (1000) for boxing or packaging articles (P) using corrugated cardboard.

[0109] Embodiments of the mechanical equipment (1000) are: - A machine (10) for supplying corrugated cardboard according to the present invention; - A machine (100) for boxing or packaging goods (P), equipped with a cardboard box entrance (101), It is equipped with.

[0110] The cardboard inlet (101) is located downstream of the cardboard supply machine (10) to receive the cardboard.

[0111] The machinery (1000) of the present invention does not require a reel of single-layer corrugated cardboard, a stack of corrugated cardboard sheets (F) i.e., a fanfold, or any other type, but directly receives strips or sheets (F) of corrugated cardboard at the outlet of a machine (10) for supplying corrugated cardboard. Thus, this machine directly services a machine (100) for boxing or packaging articles (P).

[0112] For example, various machines (100) for boxing or packaging articles (P) are known, realized in accordance with one or more of the documents in European Patent Publication No. 3947167, European Patent Publication No. 3464074, European Patent Publication No. 4117995, European Patent Publication No. 3947166, International Publication No. 2023 / 002396, and European Patent Publication No. 4157726, and are referred to herein and / or incorporated in accordance with specific standard requirements. Those skilled in the art will understand how corrugated sheets (F) can be replaced by sheets obtained by cutting fanfolds or corrugated sheets (F) joined together, by strips, or by appropriately cutting out corrugated sheets (F) to obtain blanks.

[0113] For example, the machinery (1000) shown in Figures 24 and 25 uses a machine (100) for boxing or packaging articles (P), as described in European Patent Application Publication No. 3947167, behind the cutter shown in Figure 3 of European Patent Application Publication No. 3947167. The corrugated cardboard supply machine (10), also shown in the same figure, has already produced corrugated cardboard sheets (F).

[0114] Again, as an example, the machine (10) for supplying corrugated cardboard can replace the reel visible in Figure 1 of European Patent Application Publication No. 4157726. In this case, more advantageously, a single-sided type of corrugated cardboard strip can be produced, preferably.

[0115] The machinery (1000) simplifies the supply of reels and, in particular, avoids the use of corrugated cardboard reels, or in some cases, restricts the use of single-sided corrugated cardboard. Storing smooth cardboard reels instead of corrugated cardboard reels can also reduce warehouse volume and result in economic savings.

[0116] If the machine (10) does not have a cutter (6), it is preferable that the machine equipment (1000) has a dedicated cutter for cutting corrugated strips to obtain corrugated cardboard sheets (F), which may be exactly the same as the cutter (6) or of any known type. The control unit (10a) stops the press (5) and controls the dedicated cutter so that the cutter cuts a corrugated cardboard sheet of a desired length (L).

[0117] If a cutter (6) is present, it is preferable to position the entrance (101) of the corrugated cardboard adjacent to the cutter (6) so that the corrugated cardboard crosses the entrance (101) before the cutter (6) cuts the corrugated cardboard sheet (F) or a continuous corrugated cardboard sheet (F), more preferably before the cutter cuts the corrugated cardboard sheet (F).

[0118] The machinery (1000) described above can produce boxes or customized packaging, thereby reducing the volume and / or material consumption of the packaging, as will be explained in more detail below.

[0119] A machine (10) for supplying cardboard and a machine (100) for boxing or packaging articles (P) are preferably in contact.

[0120] Thus, the overall size of the machinery (1000) is reduced, and the strips or corrugated sheets (F) do not need to be transported along a long path that could cause damage. Damage can easily occur if the adhesive (A) is not fully diffused or completely dried.

[0121] It should be noted that obtaining packaging or a box, or packaging or a box obtained, may derive advantages from corrugated cardboard in which the adhesive (A) has not been completely diffused or dried, and that after deformation, the adhesive may diffuse or dry to reach a final shape for protecting one or more articles (P).

[0122] A machine (100) for boxing or packaging articles (P) preferably includes means for determining a desired length of corrugated cardboard sheets (F) at an entrance based on one or more articles (P) to be boxed or packaged; this determining means sends a continuous value of the desired length to a control unit (10a).

[0123] As described above, the mechanical equipment (1000) of the present invention allows for significant customization in the manufacture and packaging of boxes, reducing volume and material usage. Many means are known for determining desired lengths, starting with a computer program or software that estimates the desired length based on the dimensions of one or more articles to be boxed or packaged. More known are scanners or sensor means that can measure or determine the dimensions of one or more articles (P) together.

[0124] Figures 24 and 25 show examples of scanners (104).

[0125] The machinery (1000) also includes an entrance (102) and an exit (103) for the goods when boxing or packaging.

Includes.

[0131] In this way, after proper cutting, it is possible to obtain a second single-layer corrugated cardboard sheet without any waiting period that would negatively affect the quality of the product, the integrity of the product, the integrity of the components, or the operability of the machine (10) when forming the corrugated cardboard.

Includes.

[0133] The moving device (45) and the moving mechanism (55) can clearly coexist, thereby enabling the above-described steps to be integrated between stopping and restarting.
