    DESCRIPTION Machine to print simultaneously on two parallel surfaces. OBJECT OF THE INVENTION The present invention describes a printing machine for printing decorative elements, graphics or informational legends simultaneously on two parallel side surfaces 5 of a three-dimensional object. The printing machine of the invention can also be used with a wide range of products. It has a special application in the printing of packaging, in particular cardboard packaging. 10 TECHNICAL PROBLEM TO BE RESOLVED AND BACKGROUND OF THE INVENTION In the state of the art, there are an infinity of printing machines and printing methods used by these machines. Although the progress in the printers sector has been quite significant in terms of the versatility of the printers, their accessibility and handling by personnel who do not need to have great qualification, approaching any type of users, there are still certain needs that remain unresolved, presenting a series of shortcomings in the technological advancement of the sector. Thus, printers are known for printing on both sides of a flat surface. These 20 printers are focused on printing two-dimensional elements, typically paper, and have undergone considerable progress. However, the printing of three-dimensional objects has not undergone the advance of two-dimensional printers and, despite being a growing need in the industry, 25 presents a series of shortcomings such as the limitation to the printing of graphics on a single surface already the need to specifically regulate the format by locating the heads in the desired area so that the printing matches the object on which the printing is to be performed. 30 To adapt printing to other surface formats, the printer must be pre-regulated. If you need prints on two opposite surfaces of an object, you must resort to the use of another printer arranged on the opposite side, so that each printer works on a surface of the object. All this complicates and slows down the printing processes, especially when it comes to packaging, where the volume of units to be printed is usually quite high. 5 In the current state of the art, for the printing of boxes or packaging, usually of cardboard, graphic or printing companies are used that, since they are large runs, perform printing using conventional techniques, such as flexography, pad printing, screen printing, gravure printing , etc. 10 These large runs determine the versatility when changing the packaging design or modifying it due to a product change, due to the large volumes of stock models of the different models and type of products that are packed. fifteen In addition, there is currently a tendency to use, even at points of sale, bulk product boxes or secondary packaging, such as retail displays, for which it is recommended that they incorporate some type of decoration or graphic identifying the content. The machine of the invention allows us to carry out the decoration of the packaging up to 20 degrees of extreme customization, since it is possible to decorate pre-decorated containers or boxes, but in which specific graphics can be applied for different types of products, avoiding manufacturer of multiple stocks, allowing to work with smaller runs and without resorting to other customization methods such as adhesive labels. 25 The present invention solves these problems that are not yet solved in the present state of the art, presenting a printing machine that prints simultaneously on two surfaces, achieving high performance in the printing of objects and a multi-format adaptability through modification of the structure of the machine so that it prints on any size or shape of 30 surface, in a fast and simple way. Devices capable of decorating packaging with the adaptability and versatility mentioned are not known in the state of the art. DESCRIPTION OF THE INVENTION The present invention describes a machine for printing simultaneously on two parallel surfaces of a three-dimensional object. The printing machine comprises a conveyor belt, a centering station, a printing zone and a control unit. 5 The conveyor belt has the function of transporting the objects to be printed and comprises extension means for varying the height of the conveyor belt with respect to the printheads. 10 The centering station incorporates two centering structures located symmetrically with respect to the longitudinal axis of the conveyor belt that overlaps longitudinally with the conveyor belt. The function of the centering station is to receive the objects to be printed and center them on the conveyor belt. For this, the centering structures incorporate centering elements on which the objects slide while they are moved by the conveyor belt. The centering structures have the capacity to move in the direction of approach and distance between them by means of an adjustment device that can be connected to each of the centering structures or to the assembly, so that they move simultaneously. The centering structures also incorporate extension means to vary the height of the guiding elements. twenty The printing area incorporates two mobile bases, each with at least one printhead. The mobile bases are located on each side of the conveyor belt and have the capacity to move in the two directions perpendicular to the longitudinal axis of the conveyor belt by means of an actuator and an elevator, respectively. The assembly formed by the actuator and the elevator can act on each of the mobile bases or on the two mobile bases at the same time if they are properly connected. The control unit incorporates means for acquiring dimensional data of the object 30 to be printed that have an impact on the performance of the devices that influence the configuration of the centering station and the mobile bases. It also receives data from photocells for the activation of printheads and light emitters.BRIEF DESCRIPTION OF THE FIGURES To complete the invention that is being described and in order to help a better understanding of the characteristics of the invention, according to a preferred example of realization thereof, a set of drawings is attached where, with illustrative character and non-limiting, the following figures have been represented: - Figure 1 represents a top front perspective view of the printing machine of the invention. - Figure 2 represents a plan view of the printing machine of the invention. 10 Below is a list of the references used in the figures: 1.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION 25 The present invention describes a printing machine for printing simultaneously on two parallel side surfaces of a three-dimensional object. As shown in Figures 1 and 2, the printing machine of the invention comprises a conveyor belt (1), preferably located in a horizontal position, through which the objects to be printed are to be moved. The objects enter the conveyor belt (1) through a centering station (2), which overlaps with it, consisting of two centering structures (3) located symmetrically with respect to the longitudinal axis of the conveyor belt (1) . The centering structures (3) are positioned in symmetry with respect to the longitudinal axis of the conveyor belt (1) and diverge substantially in the mouth to create a wider entrance, so as to facilitate the entry of the objects intended to be printed. Each of the centering structures (3) comprises a series of guiding elements 5 (4) for positioning the object to be printed. The guiding elements (4) located in the centering structures (3) can be, for example, horizontal rows with a plurality of rollers positioned with the axes vertically, so that the products slide laterally along the surface of the 10 rollers while they are transported by the conveyor belt (1) and remain centered in the desired position. In one embodiment, adjustment devices (7) activate the linear displacement of the centering structures (3) along guides, so that they approach or move away from each other depending on the transverse dimension between the surfaces to be printed on the object. In another embodiment, in pursuit of the effect that the object to be printed is centered with respect to the longitudinal axis of the conveyor belt (1), the centering structure (3) is joined, so that a single adjustment device (7) acts on the centering structures (3), which move symmetrically. In another embodiment, the structures (3) of the centering station (2) have the capacity to be resized in height by means of extension means, not shown in the figures, which activates the spacing between the guiding elements (4 ) along some guides depending on the height of the object to be printed. In another embodiment, the printing machine of the invention incorporates extension means, not shown in the figures, for the activation of the displacement in height of the conveyor belt (1), along guides, providing a variation in height of the conveyor belt (1) that allows the printing machine to adapt to objects of different heights. The printing machine comprises a printing zone in which there are two groups of heads (6) located in two mobile bases (5). Although each group can be formed by a single head (6), it will preferably be formed by several heads that will be aligned, preferably, in the direction of movement of the conveyor belt (1). The mobile bases (5) are located on both sides 5 of the conveyor belt (1), facing each other and, although without having to be in symmetry, symmetrically separated from the longitudinal axis of the conveyor belt (1). In one embodiment, each of the mobile bases (5) incorporates an actuator (8) and an elevator (9) as means for activating the movement along guides in the two directions perpendicular to the longitudinal axis of the conveyor belt (1), respectively, directions which, preferably, are horizontal and vertical, respectively. In another embodiment, chasing, as has been considered with the 15 centering structures (3), the effect that the object to be printed is located centered with respect to the longitudinal axis of the conveyor belt (1), the bases mobile (5) are joined, so that a single actuator (8) and a single elevator (9) act on the mobile bases (5), which move in each of the two directions symmetrically with respect to the longitudinal axis of the conveyor belt (1). twenty The printing machine of the invention also incorporates light emitters (10) which, preferably, will be ultraviolet and will be activated once printing has been carried out. Preferably they will be located in each of the mobile bases (5) The light emitters (10) are activated for curing the ink in cases where 25 is printed on a poorly porous surface and the ink requires a drying treatment. or additional cure. For this reason, they must be positioned at a place after the printhead groups (6) in the direction of advance of the conveyor belt (1). For the activation of the print heads (6) and the light emitters (10), the printing machine of the invention comprises a photocell (11) that detects the arrival of an object to be printed. The photocell (11) is located in a rail, preferably parallel to the conveyor belt (1) and fixed to a mobile base (5), so that it can be moved to determine the proximity to which it should be located with respect to the heads (6) print. Although a single photocell (11) is usually sufficient, two photocells (11), each on a mobile base (5), can be included to activate the heads (6) and light emitter (10) located in the respective side of the conveyor belt (1). 5 The transverse dimension of the object between the two parallel surfaces to be printed together with the vertical dimension of the surfaces to be printed are fundamental data for programming the printing machine of the invention that give it the versatility sought. From this data, the adjustment devices (7) of the centering station (2), the moving means of the mobile bases (5), both the actuator 10 (8) and the elevator (9) are programmed, and the means for extending the conveyor belt (1) or the existing centering structures (3), depending on the embodiment, so that they are positioned in the right place for printing the object in question. It should be noted that the movement and position of the structures (3) of the centering station 15 (2) are independent with respect to those of the movable bases (5) of the print heads (6). In the same way, the movement and position of both the structures (3) of the centering station (2) and the mobile bases (5) are totally independent with respect to the conveyor belt (1). This allows the structures (3) of the centering station (2) and the mobile bases (5) to be located in the position 20 required in each situation, giving them absolute freedom of movement. The heads (6) have the capacity to move vertically along the entire height of the object to be printed, and can even print at the zero level of the object, at the level of the conveyor belt (1). For this reason, the width of the conveyor belt (1) has a measure 25 smaller than the width of the object to be printed, which protrudes from the conveyor belt (1) on both sides. For the same reason, the centering station (2) is located before the head groups (6), in the direction of advance of the conveyor belt (1), so that they do not interfere with each other. In one embodiment, the heads (6) are aligned but positioned alternately, the ink projection zones being at different heights. The printing machine of the invention also comprises a control unit by means of which all the information related to the positioning and activation of the different electronically controlled devices is processed. 5 The control unit comprises means for acquiring data of the object to be printed, mainly in terms of dimensions. In this way, the information is sent to the control unit by, for example, reading the object by an artificial vision device, reading an identifying code or by transmitting the data from an external device or from a base of data. 10 This information determines that the printing machine modifies its printing parameters in terms of the object to be printed, affecting the need for action on the devices that influence the positioning of the centering station (2) and the mobile bases (3 ), in particular, of the adjustment devices (7) of the 15 centering structures (3) and of the actuators (8) and the elevators (9) of the movable bases (5) and of the extension means of the centering structures (3) or conveyor belt (1). The light emitters (10) are also connected to the control unit, which will be activated 20 depending on the type of packaging to be printed, as previously mentioned, and the photocells (10), which will determine the activation time of the printheads (6). On the other hand, the printing machine can also be programmed to modify only the reason to be printed in cases where the same object is supplied for different situations, such as printing the same message in different languages. The present invention should not be 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.
