    CARDBOARD BOX CORNER FORMING MOUNTING MACHINES DESCRIPTION
    OBJECT OF THE INVENTION
    image2 The present invention relates to a cardboard box corner shaper from a die cut sheet in an assembly machine. In the die-cut sheet, tabs are defined which, after being folded, define a reinforcement that is positioned in each of the corners of the box.
    The shaper is formed by a folding mechanism that is responsible for lifting the flange and folding it around the fixing plate in collaboration with a fixing mechanism for establishing the folding areas of the flanges. Subsequently, the two mechanisms are removed and the box is assembled.
    The shaper acts outside the mold, prior to the box mounting operation, so it is applicable to any box mounting system and regardless of the type of cardboard used.
    The invention also describes the corner forming procedure.
    image3
    It finds special application in the field of the industry of the mechanisms for the manufacture of cardboard boxes by folding. TECHNICAL PROBLEM TO BE SOLVED AND BACKGROUND OF THE INVENTION
    A variety of devices are known in the current state of the art in relation to the formation of cardboard boxes. These devices normally start from cardboard sheets that have previously been die-cut and marked in the positions of subsequent folding, so as to facilitate the process in the box-mounting machine.
    In the state of the art, assembly machines can be found that form boxes with all kinds of configurations, and may include, for example, covers, openings, handles or folded areas to facilitate storage at height.
    image4
    image5
    One of the most critical parts of the box, however, are the corners, since an open corner means total breakage of the box with the possibility of loss of content.
    image6 To avoid this problem, there are assembly machines that configure boxes with reinforced corners.
    Document ES-2536581_P represents a sample of this technology where a cardboard box mounting machine is described that incorporates four corner devices
    image7 mobile to have the ability to adapt to different sizes of boxes.
    The commonly applied reinforcement is simple, created by means of flanges that protrude from two parallel lateral faces of the box and that incorporate glue so that, once folded 90 degrees, they are pressed against the adjacent faces in the mold and
    image8 form the box. Another type of known reinforcement consists of a flange of greater dimensions that incorporates two folds to form a "V" with a flap, so that a triangular structure is configured and the flap serves to join adjacent faces using a glue that incorporates .
    image9 These reinforcements are created by mechanisms that, through various operations, configure the shape of the flanges that will later be attached to the adjacent face, forming the reinforced corner.
    However, the reinforced corner configuration implies that the mounting machines
    image10 are increasingly complex, influencing not only the initial cost of the machine, but also more complex maintenance.
    The present invention comes to solve this problem, which is not solved in the present state of the art, presenting a mechanism with the ability to create corners
    image11 reinforced in a cardboard box by a single operation, with the consequent savings in terms of both the cost of manufacturing the assembly machine and maintenance.

    In order to achieve the objectives and resolve the aforementioned drawbacks, the invention provides a new cardboard box corner former in forming machines, starting from a die-cut cardboard sheet in which tabs are defined to form the corners and located in areas two parallel sides of the box once assembled. The tabs are intended to be folded by means of a folding mechanism in collaboration with a fixing mechanism, by means of which the folding areas of the tabs are established so that finally said tabs are attached to the adjacent faces of the box once assembled.
    The main novelty of the inventive shaper is the fact that it is characterized by the fact that it comprises a bending mechanism that in turn comprises a vertically movable frame, which is provided with a horizontal beam, at each of whose ends it comprises a bending head, which It includes a plate, for bending the tab of two corners of the same side of the box. The plate is attached to a gear to provide it with an angular bending movement of the flange.
    These characteristics give the bending mechanism a configuration that allows the two corners to be formed in a single operation of vertical movement, up / down, of the frame and angular movement, forward / reverse, of the plate.
    In the preferred embodiment of the invention, the plate is configured by means of a thrust wing intended to bend the flange, and a pressure wing designed to configure the folding of the flange by pressure through one face. In addition, the gear is configured to provide the plate, through an arm, with a ninety-degree rotational movement. This configuration allows bending of the flanges, according to an "L" configuration, in collaboration with the fixing mechanism, as described in the embodiment of the invention.
    The invention provides that the plate is replaceable to be able to mount a plate with a configuration adapted to the different bends that are desired to be made in the flanges, such as a triangular folding, etc.
    Also in the preferred embodiment, the bending heads are located in respective oblong holes in the beam and positioned symmetrically with respect to the fixing mechanism, so that the position of each bending head is variable to adjust it to the dimensions of the box to be shaped.
    image21
    image22
    To facilitate the adjustment of the position of the bender heads, they are expected to be
    image23 mechanically linked in such a way that they move symmetrically with respect to the fixing mechanism, which facilitates and simplifies their adjustment to adapt to the different sizes of boxes.
    In relation to the fixing mechanism, it should be noted that it comprises a presser, by means of which the cardboard sheet is immobilized in the assembling machine and it also comprises two fasteners, by means of which the bending area of the two flanges is defined. corners of the same side of the box. Thus the bending of the eyelashes is carried out by means of the bending mechanism in the areas established by the fasteners.
    The invention provides that the two fasteners of the fastening mechanism are arranged in a strip by which they have the ability to slide and position symmetrically with respect to the presser, to allow their position to be adjusted adapting to the different dimensions that the boxes may have.
    To facilitate the adjustment of the fasteners, they have been mechanically arranged so that they move symmetrically with respect to the presser, which considerably simplifies this operation.
    In the preferred embodiment, the fastener has a rectangular configuration with a height that defines the fold area of the flange.
    Since most of the boxes are made up of four corners, the invention envisages that it comprises two folding mechanisms to activate them simultaneously and form the four corners of a box in a single operation.

    image36 DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    As indicated, the present invention relates to a cardboard box corner former from a die-cut sheet (1) located in an assembly machine.
    The forming of the corners consists of the creation of reinforcements by means of the bending of tabs (2) enabled on the die-cut sheet (1). Despite the fact that the configuration of this reinforcement can be made by printing various shapes or geometries, such as a triangular turret, on the flange, in the embodiment example an "L" configuration has been chosen. To carry out this configuration, the flange (2) is divided into three parts, with the lower and intermediate parts, the two closest to the cardboard sheet (1), folded one on top of the other, in a position perpendicular to the sheet (1) and the upper part resting on the cardboard sheet (1). Subsequently, in the assembly of the box and, once in the mold, the upper part of the flange (2) will be joined to the cardboard sheet (1) by the area of the adjacent lateral face. For a stable assembly, the cardboard sheet (1) incorporates glue in previously established areas where the different parts will be joined. Logically, when speaking of bonding by glue, it is done in the most open way known, and can be any type of adhesive, silicone, glue, etc.
    Knowing this configuration, the areas where glue is incorporated can be found either in the body of the cardboard sheet or in the tabs (2), this being indifferent.
    In the assembling machine there is a space in which the cardboard sheets (1) are stored and transported individually and horizontally to the forming area before being introduced into the mold pushed vertically by a pusher piston (12).

    image44
    The shaper of the invention incorporates two folding heads (6) since a mounted box will have at least two corners. A clamping mechanism (3) collaborates with the bending heads (6), as will be described.
    Figure 1 shows the forming area of a cardboard box mounting machine. In this figure you can see a cardboard box mounting machine, where you can see a pusher piston (12), one of the directing elements (11) to direct the cardboard sheet (1) to be mounted towards the mold, one of the bending heads (6) and the fixing mechanism (3) for bending the flanges (2) that will form the corners.
    Figure 2 shows the assembly machine of figure 1 in a working situation in which a die-cut cardboard sheet has been inserted to work on it. In this figure you can see the fixing mechanism (3) in the working position.
    The fixing mechanism (3) comprises, as main elements, a presser (4), in charge of fixing and releasing the cardboard sheet (1) in the assembling machine and two fixers (5), symmetrically located with respect to the presser (4) and located limiting the bending line of the tabs (2).
    In the figure it is represented how, on the one hand, the clamp (4) has been deployed to fix the position of the cardboard sheet (1). On the other hand, the clamp (4) has also been deployed to limit and define the folding position of the flanges (2).
    This position is acquired by the fixing mechanism (3) once it has been detected that there is a sheet (1) in position to be mounted. The elements of material control and determinants for the different stages of shaping the box have not been represented in the figures nor described as being common elements of the state of the art.
    In this figure 2 it can be seen how the presser (4) is basically made up of a platform (17) attached to a vertical cylinder (18) that receives energy to transmit movement. The vertical cylinder (18) is pneumatic, but could be electric or hydraulic. The presser (4) has a vertical linear movement, towards the sheet (1) to immobilize it and in the opposite direction to release it, having only the extended and retracted positions.
    image45
    image46
    On the other hand, each one of the fasteners (5) is basically composed of a projection that ends in a plate, of a certain size, moved by a pneumatic activating mechanism (13) that, as in the case of the presser (4 ), it could also be electric or hydraulic. The function of the clamp (5) is to act as a stop to facilitate the folding movement of the flange (2) once the folding head (6) is activated. The movement of the clamp (5) is linear and horizontal, having only the extended or retracted positions to
    image47
    image48 be positioned on the sheet (1) or outside it, respectively. The movement of the clamps (5) is synchronized with that of the clamp (5).
    The position of the two fasteners (5), located on each side of the presser (4), can be adjusted depending on the size of the cardboard sheet (1) to be handled. Regulation can
    image49 be done independently on each of the fasteners (5) or, preferably, on both at the same time, for which they must be mechanically connected.
    To do this, in figure 2 and, in more detail in figure 1, it can be seen how the activating mechanisms (13) of the fasteners (5) can be positioned along a
    image50 longitudinal strip (14), so that this regulation can be carried out.
    Although it may be the case that it is necessary to mount open boxes on one side, for which a single former is needed, in the assembly machine two formers are typically arranged, acting on two of the parallel sides of the sheet (1), and so ride
    image51 a box closed by its four sides.
    A bending head (6) is shown in detail in figure 3. Two bending heads (6) are fixed to a horizontal beam (15a) which, as indicated, always go in pairs and, due to the symmetry of the boxes, positioned in symmetry with respect to a fixing mechanism (3). As shown, the bending heads (6) are fixed to the beam (15a) in respective oblong holes (16), so that their position may vary. This is because the folding heads (6) can be used for boxes of different sizes. The position of each bending head (6) can be obtained manually and independently for each one of them although, preferably, the
    image52
    image53
    Positioning is done by electrical means and in unison, for which the two bending heads (6) are mechanically linked, so that there is no possibility of positioning errors.
    image54 Figure 4 shows one of the folding heads (6) acting on the flange
    (2) corresponding. This figure represents a subsequent phase to that represented in the figure
    2. This means that the bending heads (6) will only act once the fixing mechanism (3) has been extended.
    It can be seen that the folding head (6) has emerged from under the sheet (1), pushing it to position the tab (2) vertically.
    In figure 3 a bender head (6) is enlarged to see its components in detail. It comprises a plate (7) connected to a body by means of an arm (10) which, together with gears, gives it the possibility of a rotational movement. The plate (7) is configured by two wings (8, 9), a push wing (8) that acts on the flange (2) and is in contact with the flange (2) at all times in the folding process, and a pressure wing (9), in charge of maintaining the proper shape in the reinforcement configuration that is created.
    image55
    As shown in the enlarged area of figure 1, the pressure wing (9), in the rest position, is in a horizontal position, with the connection to the arm (10) made on the upper face. The push wing (8) protrudes upwards.
    The bender heads (6) have a linear vertical movement from a rest position in a lower position, to an activated position in a higher position, where it is in the working position. In this position the plate (7) is activated to proceed to the folding of the tabs (2) by means of the rotation movement. The vertical movement of the bender heads (6) is carried out by means of the vertical movement of the frame (15).
    The bending heads (6) carry out the movement from the rest position to the working position once the fasteners (5) have been extended. In this movement, each bending head (6) pushes a flange (2), through the thrust wing (8) of the plate (7),
    image56
    image57
    to leave it upright. The bending of the flange (2) is carried out aided by the corresponding clamp (5). In this movement the arm (10) has not yet been activated to move the plate (7). Once the tab (2) has been lifted in a vertical position, the plate (7) is activated, which rotates by pushing the tab (2) with the push wing (8) to proceed to fold it around the clamp (5). The movement of the plate (7) continues while the upper part of the flange (2) comes into contact with the cardboard sheet (1) and begins to fold. At the same time, the intermediate part is folded over the fastener (5) and is pressed by the pressure wing (9) of the plate (7) until the plate (7) reaches its final position in which the intermediate part the flange (2) is positioned along the clamp
    (5)  and the upper part of the flange (2) is positioned on the cardboard sheet, with the configuration in the form of "L".
    image58
    Once the corner reinforcement has been formed, the plate (7) returns to its collected position and the folding heads (6) return to their lower resting position, withdrawing from the sheet (1). For its part, the activating mechanism 13 removes the fasteners (5) in synchronization with the turning of the thrust wing (8), that is, when the thrust wing begins to rotate, the fasteners (5) are removed, and the presser (4) is activated to release the sheet. This can be seen represented in figure 6, where the cardboard sheet (1) is left with the tabs (2) folded.
    image59
    From this moment, the pusher piston (12) comes into action, which pushes the sheet (1) towards the mold aided by the directing elements (11) for mounting the box.
    Figure 7 represents the box entering the mold to be assembled with the tabs (2) already formed and the rest of the box is made in a conventional way, so it is not described as it is not the object of the invention.
    It should be noted that the present invention is limited to the embodiment described herein. Other configurations can be made by those skilled in the art in view of the present description. Accordingly, the scope of the invention is defined by the following claims.
