    [0002] SYSTEM AND METHOD OF DECORATING SUITCASES AND LUGGAGE ITEMS
    [0004] OBJECT OF THE INVENTION
    [0006] The present invention relates to the technical field of digital printing and more specifically to a system for digital printing and drying in line, in a single pass, of suitcases and luggage items, especially rigid or semi-rigid, made of materials such as ABS ( Acrylonitrile Butadiene), PC (Polycarbonate), PP (Prolippropylene), PET (Polyethylene Terephthalate), among others; and a method for digital printing of suitcases and luggage items.
    [0008] BACKGROUND OF THE INVENTION
    [0010] Today the number of people traveling has increased. This change in people's mentality is due, among other factors, to the cheaper airline tickets, the improvement of infrastructures for cars and trains, the greater access to information available thanks to the internet, social media, etc.
    [0012] Based on the growing use of means of transport, the consumption of suitcases and luggage items has increased, essential for people who travel to transport their belongings comfortably. Inside the luggage items are for example backpacks, toiletry bags, etc.
    [0014] Likewise, the concept of travel and the ways of traveling have been adapted to the needs of society and more and more travelers are traveling as a family, or accompanied by young children. In this sense, consumer needs have allowed the development of small suitcases and luggage items that can be transported by children themselves with their belongings. The fact that each child carries their own suitcase or item of luggage allows them to work on their independence and their responsibility when preparing the suitcases for the trip and taking care of their own luggage.
    [0015] On the other hand, in today's society there is a growing demand for personalized or customizable objects. More specifically, most users want to be able to create exclusive designs tailored to their own tastes.
    [0017] Likewise, without the need to demand complete customization, users do adapt quickly to different fashions and the concept of “fast fashion” is increasingly extended in which different trends are quickly adapted to consumer objects , so that users can change objects based on trends from season to season.
    [0019] The materials that predominate lately refer to those used in suitcases and completely rigid or semi-rigid luggage items, which provide a certain degree of flexibility, such as ABS (Acrylonitrile Butadiene), PC (Polycarbonate) or PP (Polypropylene) among others, which provide greater content security, and four wheels for greater comfort on the move. On these materials, it is necessary to include the different colors, designs, brands, prints or customizations required to adapt to the consumer's taste.
    [0021] In order to incorporate a design in a suitcase or rigid luggage items, whether made of ABS or PC, according to traditional manufacturing systems, it is used to engrave it on plates or molds, which are subsequently applied on a sheet. The film is integrated into the surface of the product during the manufacturing process, where it is swollen and formed by heat, thus giving rise to the final format of suitcases and luggage items.
    [0023] One of the problems derived from traditional methods and systems is that it is not possible to ensure homogeneous runs, since when the material swells by heat and is deposited on the mold to take shape, and then return to its cold state, it is often distorts the design. For images of people or characters, for circles, shields or other designs that require precision, this is a problem because normally the distortion is considerable and the final effect is not acceptable.
    [0025] On the other hand, each color that incorporates the design has high costs that, multiplied by an average of about ten colors that each suitcase and / or luggage item usually has, makes the average design costs per product very high, regardless of the production quantities that are made. The problem of high costs for each design would not be such if the runs were made for large quantities, but this is not the current reality, so costs make the production of designs for small runs on many occasions unfeasible.
    [0027] Another added problem refers to versatility and flexibility burdened by manufacturing times. Traditional methods and systems imply a preparation, adjustment and production time, for a single sample, which can be between 15 days and a month.
    [0029] Additionally, it is important to note that users, when acquiring a suitcase or luggage item, demand that it be in perfect condition. Thus, it is necessary that any system or method of manufacturing or customizing suitcases and luggage items has the necessary means to ensure that the suitcase or luggage item is kept in perfect condition during said operations and allows design variations to taste.
    [0031] In summary, currently the integration of design, color, pattern or customization during the manufacturing process of rigid or semi-rigid suitcases and luggage items is a long and expensive process that makes the sector not very versatile in adjusting designs to parameters of precision, flexibility, speed, simplicity and cost that are required today. In addition, it is currently necessary to produce many different designs quickly, which is lacking in the state of the art to achieve a unique, personalized product that meets the quality standards demanded by consumers.
    [0033] State-of-the-art documents are known in which suitcase printing can be made in systems and with static methods, while the market needs point to dynamic systems and methods that allow a more versatile and faster printing.
    [0035] DESCRIPTION OF THE INVENTION
    [0036] The present invention describes a system and method for stamping suitcases and luggage items in digital printing and drying in line, in a single pass. It is an online digital printing system for suitcases and luggage items that is a dynamic solution for the decoration of toiletry bags and all kinds of luggage. It is a mass production system that allows the printing of suitcases and luggage items of individualized form, thus achieving greater versatility. A method for digital printing of suitcases and luggage items is also proposed.
    [0038] It is a dynamic printing system, where each suitcase and luggage item is transported individually by a printing line such that it can be printed one by one, thus achieving greater versatility, by allowing different types of exclusive decorations.
    [0040] The system has a traceability and monitoring system for each suitcase and luggage item, a color printing module for suitcases and luggage items online and means for moving suitcases and luggage items that are synchronized with each other to avoid possible bumps between suitcases and luggage items.
    [0042] In cases where there are blockages in production lines, many products can collide or touch and become marked. If there is any rub or blow between the suitcases and / or luggage items and these become marked or deformed, they can no longer be sold. To avoid this, the moving means comprises a plurality of individual conveyors, so that a single suitcase or item of luggage is located on each conveyor at any one time. Said individual conveyors are arranged forming a linear path of passage of suitcases and luggage items.
    [0044] Thanks to the traceability and tracking system, it is possible to control the position of each suitcase and luggage item in the system precisely and in real time, and associate each of said suitcases and luggage items with an image to be printed and / or some different image colors. Thus, the versatility of the system is greatly increased by allowing a different image to be printed on each suitcase and item of luggage that passes through the printing module.
    [0046] Said traceability and monitoring system can be automated or manual. Thus, in a preferred embodiment, it may comprise the use of individual item identification codes. In another preferred embodiment, the traceability and monitoring system and process does not use said codes, but rather an operator who personally controls the type of printing of each item.
    [0047] The system also allows double-sided printing on suitcases and luggage items. To do this, the system includes two exit lanes to which suitcases and luggage items are directed after passing through the printing module. Depending on the identification code associated with each suitcase and item of luggage, or at the discretion and instructions of the operator, it is sent to an exit lane for semi-finished products or a final exit lane. The exit lane for semi-finished products receives suitcases and luggage items that have already been printed on one side but will also be printed on the other side. The final exit lane receives suitcases and luggage items that have already been double-sided, or suitcases and luggage items that only need one-sided printing.
    [0049] It is essential that the suitcase and luggage items moving through the system and entering the printing module have at least one flat side or one flat section on one side on which to print. Said flat side, or flat section of a side, is the printing side on which the image is to be printed. The suitcase or luggage item is arranged in a position where, upon entering the printing module, the printing side (where there is a printing area in which the image is to be printed) is facing heads printing of said printing module.
    [0051] This flat face (or flat section for printing) must always be at a certain height relative to the print heads that must be within a printing tolerance. It is a necessary condition to guarantee a correct printing process. The area of the suitcases or luggage items in which the printing is to be made must always be in a single printing plane.
    [0053] The system is specially designed to be used with suitcases and rigid or semi-rigid luggage items, so it can be used without the need for additional molds or supports. However, in an embodiment in which it is desired to print small-sized suitcases and luggage items, the system comprises coupling means intended to receive said suitcases and luggage items and keep them in a fixed position. These coupling means can be supports, in the manner of trays. The size of the supports depends on the size of the individual conveyors, such that they are configured so that a single support is on an individual conveyor at any one time.
    [0054] One or more suitcases or luggage items can be arranged on the supports, depending on their size. For this, each support comprises at least one housing configured to receive a suitcase or luggage item.
    [0056] It may also be necessary to use these coupling means (supports or buckets) in cases where the suitcases and luggage items have a flat face but it is not arranged parallel to an upper surface of the individual conveyors and therefore will not be perpendicular. to the print heads. In these cases, the housings of the coupling means (supports or buckets) can have a special configuration to achieve that, when positioning the suitcases or luggage items in them, the flat face or flat section of one face is arranged in a a correct printing plane.
    [0058] The system may comprise a preparation module, prior to the printing module, in which the suitcases and luggage items are placed, each suitcase positioned or the luggage accessories positioned on an individual conveyor, and where it is associated with each suitcase or item. of luggage its corresponding identification code generated by the traceability and tracking system. In this preparation module, suitcases and luggage items are placed on racks when necessary.
    [0060] The system may comprise at least one height detector, configured to detect the height of suitcases and luggage items. Said height detector can be arranged prior to the printing module or at its entrance and have the function of adjusting the height of the heads to the suitcase or travel item to be printed, in order to obtain an optimal printing result.
    [0062] In a preferred embodiment, the system comprises an artificial vision system configured to detect quality failures. The artificial vision system can be arranged in the printing module or, for example, form part of an inspection module, arranged after the printing module. The artificial vision system is configured to scan the face of the suitcase or luggage item on which the impression has been made to detect if there are errors, for example, in the application of colors, or in the shapes of the image, etc.
    [0064] In another embodiment, the system also comprises a protection module. This protection module can comprise an automatic device for placing film that selects the type of film, generally plastic, to be applied based on the information in the identification code. In general, this protective film ensures the integrity of the suitcase or luggage item.
    [0066] The traceability and tracking system can generate and be based on, as previously described, a unique two-dimensional code associated with each suitcase or luggage item. This generated code, called an identification code, is stored in a remote database. The identification code can include data such as the total dimensions of the suitcase and luggage items, if it is to be printed on one side or on two sides, what is the image to be printed, the color profile to be used in printing, the type of suitcases and luggage items that it is (and that defines which exit lane it is sent to), the date / time / encrypted batch data and / or empty fields that can be filled in by the system itself later, such as which one is the printed side and whether the print quality is acceptable or not.
    [0068] In an exemplary embodiment, the traceability and tracking system generates a label with the identification code, configured to be removably attached to suitcases and luggage items (such that it can be removed when the printing process is finished). Preferably, the tag is always placed on suitcases and luggage items in the same position.
    [0070] Said system comprises, in this embodiment, a first code reader configured to read the identification code of each suitcase or luggage item and send the corresponding work order (with the data obtained from said identification code) to the traceability system and tracking, the means of movement and the printing module.
    [0072] The first code reader is arranged at the entrance of the printing module or before said printing module in order, based on the information of the identification code, to calibrate certain parameters of the printing module, such as the height and lateral compensation. of the print heads (which depend on the measurements of each suitcase and luggage item), the image to be printed and the color profile to be used.
    [0074] A second code reader is located at the output of the printing module and / or the output of the inspection module and / or the output of the protection module. As described In advance, based on the information in the identification code, the suitcase or baggage item is sent to the exit lane for semi-finished products (if another side of the suitcase or baggage item has to be printed) or sent to the final exit lane .
    [0076] In cases where suitcases and baggage items are sent to the semi-finished goods exit lane, each suitcase and baggage item is turned over and placed in the picking module again. In a preferred embodiment, said operation can be carried out by an operator. In this way, the suitcase or luggage item is again passed through the printing module to make printing on an additional printing side.
    [0078] Preferably, the system comprises a lateral band, which acts as a guide for the suitcase or luggage item along the linear path of passage of suitcases and luggage items. In this case, all the suitcases or luggage items to be printed must have a flat side face, which is at least the height of the side strip, to be able to position the identification code. If the use of a support is necessary, the suitcase or luggage item housed in the support must be at least that high.
    [0080] The system may additionally comprise an antistatic bar configured to discharge from the suitcases or luggage items any possible accumulation of static electricity caused, especially, by the previous removal of the protective film.
    [0082] In the printing module there are means for adjusting the height and position of the printing heads that are in charge of raising or lowering the heads and moving them linearly to the right or left until they are in the desired position with respect to the suitcases and luggage items. to print. This regulation is carried out automatically based on the information of the identification code of each suitcase or luggage item. It is essential that the height of suitcases and luggage is maintained during printing to ensure correct printing quality.
    [0084] The printing module can also comprise a primer unit, a color unit, an effect unit and one or more drying units depending on the needs. The at least one drying means may preferably be a drying lamp.
    [0085] In the primer unit a line of nozzles is extended to make a white primer or base on the suitcases and luggage items that need it, which are suitcases or luggage items of dark colors. This white primer must be exactly the same as the image to be printed so that there are no white outlines without color.
    [0087] The color unit contains the print heads. It is set to print the image in color.
    [0089] In an exemplary embodiment, printing is performed by four-color techniques using CMYK inks or OVG inks. For this, the system comprises CMYK color lines and / or OVG ink lines. The system could also comprise two heads with SPOT colors (predefined colors, that is, printing is done directly with these colors and not with the basic colors: magenta, yellow and cyan).
    [0091] In this color unit there are a plurality of color bars, which have an electronics section in which the connections to the traceability and monitoring system are established, a head bar and a main ink tank. It may also comprise an automatic cleaning zone. Said color bars are preferably removable, to ensure easy replacement in the event of a failure. By removing each color bar, you have access to the corresponding print head attached to it in order to perform maintenance operations. In addition, the main tanks can be filled continuously, without having to stop production.
    [0093] Glossy effects, varnishes, etc. can be applied to the effect unit, which is part of the printing module. In this way, different shades, brightness, or a feeling of thickness is achieved in different areas of the image.
    [0095] One or more drying lines are located in the system, for example a first drying line located between the primer line and the four-color lines, a second drying line between the CMK color lines and the OVG inks, a line drying at the end of the color and before the finishes, as well as a final. Whenever a print or finish is applied, it is necessary to have drying media. In a particular realization of the Invention, the drying line may comprise a drying tunnel, for example by UV (ultraviolet) rays to fully fix the printing ink.
    [0097] It is also an object of the present invention a method for digital printing of suitcases and luggage items comprising at least the steps of: placing suitcases and luggage items on individual conveyors; assign an identification code to each suitcase and luggage items; detecting the presence or absence of suitcases and luggage items on each of the individual conveyors and synchronizing the movement of the individual conveyors.
    [0099] In the event that the presence of the item to be printed is not detected on a second individual conveyor, a step is carried out of moving the suitcase or item of luggage that is on a first individual conveyor towards said second individual conveyor, so that the suitcases and items of luggage move along the linear path of the system.
    [0101] In the event that the presence of the item to be printed is detected on a second individual conveyor, if the conveyor belt is moving to move the suitcases and luggage items to the next individual conveyor, a step of moving the suitcases and luggage items is performed from a first individual conveyor (prior to the second individual conveyor) to said second individual conveyor; if said second individual conveyor is stopped, a step of stopping the first individual conveyor is performed.
    [0103] The method also comprises the step of collecting and recording information for each suitcase and baggage item entered into the system. This action can be carried out by an operator, or in a preferred embodiment it is possible to automate the process, reading the identification code of each suitcase and luggage item and storing the associated information; and when a suitcase or item of luggage arrives at the printing module, printing an image on said suitcase or item of luggage based on its identification code (or based on the action of the operator, who controls it manually).
    [0105] Preferably, in this embodiment in which a tracking and traceability system is used, the method also comprises a step of reading the identification code of the suitcase or luggage item as it exits the print module. This stage makes it possible to determine whether the suitcase or the item of luggage is sent to an exit lane for semi-finished products, from where it will be collected to be placed back in a loading module / preparation module or at the entrance of the printing module; This action can be carried out by an operator or it can be systematized. This occurs in cases where, depending on the identification code, the suitcase or luggage item is to be printed on more than one side. In this case, these are suitcases and luggage items that have already been printed on one side of the print and are now to be printed on one additional side of print.
    [0107] As previously described, in cases where suitcases and luggage items are only going to be printed on one side, or when they have already been printed on both sides, the printing code is read at the output of the printing module. identification and the suitcase or item of luggage is sent to a final exit lane.
    [0109] The method may also comprise subsequent steps of checking the quality of the printing and / or the placement of a protective film.
    [0111] In the event that the method is used for printing suitcases and small-sized or specially shaped luggage items, this method comprises a step of placing the suitcase or luggage item on a support designed for this purpose, which ensures the position. of the suitcase or item of luggage throughout the journey and prevents such luggage and small items of luggage from colliding with each other and shifting during movement of the system.
    [0113] It is therefore a system that allows linear digital printing of suitcases and luggage items without necessarily having to do batch printing. When each suitcase or luggage item is associated with an identification code, when said suitcases and luggage items arrive at the printing module, the corresponding image is printed / stamped, which may vary between suitcases and items. consecutive luggage. The system allows users to meet the demands of quality and variability of user designs, avoiding scratches or bumps on suitcases or luggage items and providing a wide variety of models.
    [0114] In the same way, the described method allows online digital printing of suitcases and luggage items, ensuring correct print quality and avoiding possible damage to suitcases or luggage items during the entire printing procedure. The method adapts each impression to the corresponding suitcase or luggage accessory based on the identification code associated with it.
    [0116] BRIEF DESCRIPTION OF THE FIGURES

    [0126] DETAILED DESCRIPTION OF THE INVENTION
    [0127] The present invention discloses a method and a system for digital printing of suitcases and luggage items and drying line, in a single pass, with which the personalized stamping of suitcases and luggage items is achieved while protecting said suitcases and luggage items. baggage from possible knocks to ensure correct quality of the final printed suitcase or baggage item.
    [0129] Figure 1 shows a top view of the digital printing system for suitcases and luggage items (1) while, in Figure 2, the system is shown in an elevation view.
    [0130] The system comprises means for generating the identification code of each suitcase and luggage items (1) configured to generate a unique two-dimensional code associated with each suitcase and luggage item (1). Through this code, suitcases and luggage items (1) are fully located in the system during the entire time they are in it. The unique code data is stored in a remote database.
    [0132] In addition to allowing the traceability of suitcases and luggage items (1), the code includes the characteristics of the suitcases and luggage items (1) that will be necessary during decoration operations. That is, the code can include information on the size of the suitcase or luggage item (1), on the image to be printed on said suitcases and luggage items (1), information on whether it is printed on one side. or two, etc.
    [0134] The system comprises a printing module (2) configured to print an image on the suitcases and luggage items (1) based on the identification code associated with said suitcases and luggage items (1) and a traceability and tracking system configured to determining the position of each suitcase and baggage item (1) in the system from its identification code as previously described.
    [0136] Likewise, the system comprises moving means configured to move the suitcases and luggage items (1) along the system. The displacement means comprise a plurality of adjacent individual conveyors (3), forming a linear path of passage of the suitcases and luggage items.
    [0138] Figure 1 shows an embodiment in which the system comprises a loading module (14) configured to receive suitcases and luggage items (1), followed by a preparation module (15) in which assigns the identification code to each suitcase and luggage item (1), before the printing module (2) configured to print the corresponding image on each suitcase and luggage item (1); a rear inspection module (13), configured to scan the suitcases and luggage items (1) and determine if the printing has been correct; a protection module (12) with at least one automatic positioning device configured to apply a protective film, which is preferably plastic, on suitcases and luggage items (1) and exit rails (7, 8) for removal of suitcases and luggage items (1).
    [0139] In figure 2 the same system has been represented but in an elevation view.
    [0141] In Figures 3A-C an individual conveyor (3) is shown in different views. More specifically in figure 3A an individual conveyor (3) can be seen in a perspective view in which a frame (4) is observed, an individual conveyor belt (5) extending along an upper surface of the frame (4) and a motor (6).
    [0143] As can be seen in figure 3B, which is a top view of the individual conveyor (3), it may comprise more than one conveyor belt (5) in the event that these have a width less than that of the upper surface of the frame (4 ) or for example due to other geometric motifs. The motor (6), which is an individual motor for each conveyor (3), controls the movement of the conveyor belt or belts (5). Figure 3C shows an elevation view of the individual conveyor (3) in which the frame (4) and the motor (6) are clearly seen.
    [0145] Likewise, each individual conveyor (3) comprises a sensor for the presence of suitcases and luggage items.
    [0147] An essential feature of the present invention is that the individual conveyors (3) are synchronized with each other such that suitcases and luggage items (1) found on a first individual conveyor (3) only move to a second individual conveyor ( 3) adjacent to it when it is detected that the suitcases and luggage items (1) arranged on said second individual conveyor (3) are moving or have moved to the next individual conveyor (3) or have been removed from the system, thus avoiding possible knocks between suitcases and luggage items (1).
    [0149] Thus, if the presence of a suitcase or luggage item (1) is detected on a subsequent individual conveyor (3), the passage of suitcases and luggage items (1) found on the individual conveyors (3) is stopped or delayed ( 3) prior to those involved in the traffic jam, slowing down the movement to prevent suitcases and luggage items (1) from coming into contact with each other.
    [0151] Preferably, when the printing system comprises a monitoring and traceability system, the latter system comprises a first code reader arranged prior to the printing module (2) or in this, configured to read the identification code of suitcases and luggage items and send the information to a remote database. Reading the identification code prior to entering the printing module (2) makes it possible to adapt the variable parameters of the components of the printing module to each specific suitcase and luggage item (1) to be decorated.
    [0153] Likewise, the system preferably comprises two exit rails (7, 8), as seen in Figure 1, arranged behind the printing module (2). These lanes are an exit lane for semi-finished products (7), to which suitcases and baggage items to be printed on two sides are sent, and a final exit lane (8), to which suitcases are sent and luggage items that only print on one side or those that have already been printed on two sides.
    [0155] Preferably, the system comprises a second code reader configured to obtain the identification code information for each suitcase or baggage item and, depending on it, direct the suitcases and baggage items to the semi-finished products exit lane (7) or to the lane end outlet (8). In an exemplary embodiment, the second code reader is arranged at the output of the printing module (2).
    [0157] Thanks to the fact that the system sends the suitcases and luggage items directly to one or another exit lane (7, 8), operators do not have to be aware at all times of which suitcases and luggage items are already finished and which ones still need to be rotated to be reprinted. In addition, human errors are avoided due to lack of knowledge or ignorance. Operators know directly that suitcases and luggage items found in the semi-finished products exit lane (7) have to be reloaded into the loading module (14) (or at the entrance of the printing module (2) if the system does not have a loading module (14) or a preparation module (15)). Likewise, suitcases and luggage items (1) that the system has sent to the final exit lane (8) are already removed from the system.
    [0159] In a preferred embodiment, the system also includes a height detector, arranged prior to the printing module (2) or at its entrance, configured to adjust the height of the heads to the suitcase or travel item to be printed, in order to obtain an optimal printing result.
    [0160] As previously described, the position of the print heads is regulated automatically. For this, the system comprises means for adjusting the height and position of the printing heads configured to raise and lower the print heads and move them linearly to the right or left until they are positioned in a desired position with respect to the suitcases and luggage items to to print. This allows printing on suitcases and luggage items (1) of different heights and / or different dimensions of the printing side. In addition, by positioning the head in the specific area in which you want to print, it is not necessary that all suitcases and luggage items (1) have the image printed in the center but it can be printed, for example, near a corner of the suitcase or luggage item (1).
    [0162] The printing module (2) may also comprise a primer unit configured to spread a primer layer on the printing side of the suitcase or luggage item (1).
    [0164] The printing module (2) further comprises a color unit with at least one color bar comprising an electronics section configured to connect with the traceability and monitoring system, printing heads and a main ink tank.
    [0166] Additionally, the printing module (2) may comprise an effect unit configured to perform additional digital printing on the image printed on the suitcase or luggage item (1). Likewise, the printing module (2) preferably has a drying unit with UV ray generation devices configured for drying and fixing the ink of the printed image.
    [0168] To ensure a correct quality of the suitcases and luggage items (1) coming out of the system, the system may comprise artificial vision means configured to scan the printing side of each suitcase and luggage item (1) and detect possible failures of Print. These artificial vision means can be housed in the printing module (2) or in an inspection module (13) arranged behind the printing module (2). In cases where the system includes a second code reader, this may be arranged at the outlet of the inspection module (13).
    [0169] As shown in the example of figure 1, the system can also comprise a protection module (12) in which there is an automatic device for placing a protective film on the printing side of the suitcases and articles of luggage (1). In the event that the system comprises a second code reader, this can be arranged at the output of the protection module (12).
    [0171] Figure 4 shows a side band (9) that can form part of the system and has a certain height, and acts as a guide for suitcases and luggage items (1) along the system.
