    CROSS REFERENCE TO RELATED ORDERS
    [0001] This application claims priority from North American Interim Application No. 61 / 704,407, entitled Printing System, filed September 21, 2012 and to US Provisional Application No. 61 / 704,406, entitled large format printer, filed 21 of September 2012, each of which are incorporated herein in their entirety by this reference. FIELD OF THE INVENTION
    [0002] The invention relates to the field of printers. More particularly, the invention relates to structures and fastening devices that enable the accurate installation, removal and reinstallation of modular print bar systems in a print environment. BACKGROUND OF THE INVENTION
    [0003] Conveyor belt systems have long been used to transfer objects such as materials, objects, substrates, and work pieces. In such environments, the transfer belt is suspended between a plurality of rollers, one of the rollers, i.e. a drive roller, is typically connected to a drive mechanism, eg a motor, such that the movement of rotation of the drive mechanism in rotational movement results in a rotational movement of the drive roller, which moves the belt in relation to the rollers, providing linear movement.
    [0004] Printing systems often use conveyor belt systems to transfer workpieces such as but not limited to flexible substrates, eg paper or film, or rigid substrates eg ceramic tiles. In a printing system, ceramic tiles are arranged on top of a conveyor belt, and are moved through a printing zone, which typically includes a plurality of print bars, each of the print bars comprising a plurality of print heads that are configured to controllably deliver ink onto the ceramic tiles as they are moved through the print zone.
    [0005] In such systems, it is typically critical that the location of a workpiece in relation to each print zone is known, such that the ink jet for each print bar, and for each of the print heads , on each print bar, is properly delivered to the piece.
    [0006] The required resolution of delivered ink has increased over time, such that demands for greater accuracy can extend beyond the accuracy with which workpieces can be located and moved, particularly within a working environment. production, in which workpieces are often required to be accurately moved through one or more printing zones while delivering ink to the workpieces.
    [0007] For printing systems in which the print bars are removable, it is necessary to accurately position the print bars in relation to the transfer belt, and with respect to other print bars, in which each of the print bars defines accurately a corresponding print zone, such that the print heads associated with each of the jet print bars can accurately the workpieces.
    [0008] It has previously been time-consuming and expensive to install or replace one or more print bars within such a printing system, which often results in accurately significant downtime.
    [0009] Therefore, it would be advantageous to provide structures and/or systems that are configured to provide an accurate installation, removal and reinstallation of one or more print bars within such print system. The development of such structures and/or systems would constitute an important technological advance.
    [0010] Printing systems often require multiple inks, coatings, enamels, or other liquids to be blasted onto a workpiece in a production environment. The cost and space required for these installations are often substantial.
    [0011] Furthermore, the needs in such manufacturing environments change frequently, as in the short term, for example, different projects or production shifts, and/or the long term, for example, changing product lines or business strategies . Conventional printing systems are not easily reconfigured to meet these needs.
    [0012] Therefore, it would be advantageous to provide advanced printing structures and systems that are highly configurable, to meet any of the short- or long-term needs of a manufacturing facility. The development of such structures and/or systems would constitute an important technological advance.
    [0013] In addition, it is often necessary to perform one or more print bars in a printing system. If one or more print bars are in need of a given service, the printing system is normally turned off, until such time as all print bars are again ready for use.
    [0014] Therefore, it would be advantageous to provide structures and printing systems that provides decreased service time. The development of such structures and/or systems would constitute an important technological advance.
    [0015] Thus, it would be advantageous to provide structures and systems that provide one or more redundant print bars(s), so that the system is configured to switch between print bars as needed or desired, and in which at least one The print bars can be removed from an active line and repaired or replaced, while the print system can continue to operate, transitioning between different print bars. The development of such structures and/or systems would constitute an important technological advance.
    [0016] Some background can be found such as JP 2002 240260 which refers to a printer designed in such a way that consumables such as ink cartridges and ink ribbons can be readily replaced. Consumables are provided in a cartridge tray that can be inserted and removed from the printer body. Consumables can be detachably attached to the cartridge tray and therefore can be easily changed simply by pulling the cartridge tray out of the printer body.
    [0017] Historically, printing systems required that various inks, coatings, enamels and other liquids be injected into workpieces. Replacing these materials can be costly as they may require an entire print bar to be removed and then reinstalled. The present invention was developed in an effort not only to decrease the time required to replace materials, but also to ensure that print bars are properly reinstalled after replacement.
    [0018] A new aspect of the present invention is that a pair of attachment structures are provided for attaching a print bar to a chassis of a print system. The first fastening structure may comprise (i) a sliding assembly that allows the print bar to be slidably moved relative to the chassis between a first position, in which the print bar is aligned with a corresponding housing, and a second position, in which the print bar is released from the corresponding compartment; and (ii) an alignment mechanism for positioning the print bar with respect to the corresponding compartment. The alignment mechanism may comprise (i) an attachment platform that has one or more holes defined therein and (ii) one or more alignment pins that are configured to slidingly engage the holes when the print pair is moved to the first position. Meanwhile, the second attachment structure may comprise (i) a latch which is attached to the chassis; (ii) an actuator that is attached to the print bar; and (iii) a pin mechanism, affixed to the latch or actuator, which is configured to lock the latch and actuator together when the print bar is in the first position. SUMMARY OF THE INVENTION
    [0019] Enhanced fastening systems and associated structures are configured to provide accurate installation, removal and reinstallation of printbar systems in a print environment. In an exemplary embodiment, the connecting system comprises one or more corresponding fastening assemblies comprising tabs and pins, wherein the latches are fixedly disposed relative to the print bar guides, and wherein each of the bars The printout is slideable relative to a corresponding bar tab printout. When a print bar is aligned alignably with respect to a corresponding print bar guide, a corresponding pin is capable of being secured to the closure, precisely affixed to the print bar relative to the print bar guide.
    [0020] The clamping mechanism provides repeatable registration of the print bar in relation to the print system. In some embodiments of the system, the improved connection system comprises actuators, for example pneumatic actuators or electric actuators, with which to engage or disengage the pins with respect to the latches. The system can preferably be configured to provide any automatic engagement or disengagement of the actuators. BRIEF DESCRIPTION OF THE DRAWINGS

    [0039] Figure 1 is a schematic diagram of an exemplary modular printing system 10 having a conveyor assembly 14 for transporting one or more WP workpieces in relation to an array 40 of one or more print bars 42. Figure 2 is a side view 60 of an improved exemplary modular printing system 10. Figure 3 is a detailed partial perspective view 80 of an exemplary conveyor assembly 14 associated with an improved modular printing system 10.
    [0040] The exemplary conveyor assembly 14 seen in Figure 1 comprises a transfer belt 18 extending between a plurality of rollers 16, eg 16a, 16b, which are rotatably mounted relative to a chassis 12. It should be understood that the modular exemplary improved printing system 10 seen in Figure 1 presents a simplified view of the printing system 10. For example, the conveyor assembly 14 may further comprise one or more additional rollers, such as a tension roller 52 is related to a tensioning mechanism 72 (Fig. 2), and/or the transfer rollers 16 and belt 18 may further comprise a belt locking mechanism 96 (Fig. 3), such as, but not limited to, a plurality of teeth 96 which gear. Similarly, the improved printing system 10 preferably comprises additional structures and mechanisms to provide better dimensional tolerances whether in installation, operation, or longevity.
    [0041] The exemplary conveyor assembly 14 seen in Figure 1 is typically operated by a drive mechanism 26, which controllably rotates one of the rollers 16, eg 16-A, thus producing the movement of the transfer belt 32, through which one or more WP workpieces, eg ceramic WP tiles, are moved in a controlled manner, such as to be operated in one or more locations with respect to system 10. Although exemplary printing system 10 is described herein with respect to one or more WP workpieces, eg ceramic WP tiles, it is to be understood that the structures and systems described herein can be easily applied by a printing system 10 associated with other workpieces or substrates such as such as, but not limited to, any of paper, film, textile, or other articles of manufacture.
    [0042] The drive mechanism 26 typically comprises a drive motor 142 (Fig. 6) and a coupling mechanism, e.g. a transfer unit 144 (Fig. 6), wherein the drive motor 142 is moved in a controlled manner via a controller 20, for example a programmable logic controller (PLC). Motor mechanism 26 may preferably comprise one or more improved structures to provide highly accurate and repetitive location and motion.
    [0043] The improved modular system 10 may preferably include an encoder 28 so as to provide precise controlled movement 32 of the transfer belt 18 via the drive mechanism 26. The controller 20 typically comprises one or more processors 22, eg 22a-22e, and may also comprise storing 24 eg memory, such as by, but not limited to, storing any of the operational parameters, thresholds, operational history, and/ or screening. Controller 20 is typically configured to control all movements and operations in print system 10, such as, but not limited to, movement of transfer belt 18 via drive mechanism 26, and coordinate operations of print bars 42, for example, 42a-42h.
    [0044] As also seen in Figure 1, a display 34 and a user interface 36 are also typically connected to the controller 20 so as to provide input to a user USR user, eg an operator, and/or the provide information to the USR user. Thus, printing system 10 may further comprise a communications link 46, through which controller 20 may preferably be configured to transmit an output signal 48 and/or receive an input signal 50.
    [0045] The exemplary improved modular printing system 10, seen in Figure 2 and Figure 3, is configured to print on ceramic WP tiles, and may preferably comprise one or more workpiece guides 98 (Fig. 3), upstream of one or more of the print bars 42, such as in the inlet area 86 (FIG. 3) of the transfer belt 18. Ceramic tiles WP that are placed on the transfer belt 18 may initially not be located with a great degree of precision, and/or can be twisted, ie rotated. The workpiece guides 98 ensure that the WP tiles are in the proper place, on the transfer belt 18, for example in the middle, and that the WP tiles are acceptably linear, for example within an acceptable range.
    [0046] The improved exemplary printer modular system 10 seen in Figure 2 and Figure 3 may preferably comprise an improved tension adjustment mechanism 72 for the transfer belt 18. For example, as during any initial setup, belt replacement, or other service, a thread, i.e. screw guide mechanism 102 (Fig. 4) can be rotatably moved so as to provide fine adjustment of the linear distance between rollers 16, for example , 16a, 16b, to obtain a desired tension in the transfer belt 18, as recommended by the manufacturer of the transfer belt 18.
    [0047] Likewise, for the adjustment of parallelism between the rollers 16, the tensioning mechanism 72 may preferably comprise a pair of guide screws 102, for example 102a, 102b, on opposite sides of at least one of the rollers 16, for example 16a or 16b. One or both guide screws 102, e.g. 102a and/or 102b, may preferably be adjustable to achieve parallelism between roller 16 and transfer belt 18, i.e. to achieve 90 degrees between roller axis 16 and the longitudinal axis of the transfer belt 18.
    [0048] In some embodiments, a screw guide assembly 102 associated with a first roller 16, eg 16a, can be considered a primary or main guide mechanism 102, which can be adjustable for parallelism when the corresponding roller 16 is free for adjustment either by parallelism or by tension, i.e. not locked, such as when the position of the opposite roller 16, eg 16b, is maintained. Similarly, the opposite roller 16, eg 16b, can be adjustable for any parallelism or tension, i.e. not locked, such as when the position of the opposite roller 16, eg 16a, is maintained. The USR operator can then determine when cylinder 16 is aligned with workpiece guide 98, which ensures that transfer belt 18 is parallel to opposite roller 16 and aligned with transfer belt 18.
    [0049] Once the transfer belt 18 is set in parallel, with the proper tension, the screw guide mechanism 102 is tightened, and the part guide 98 is put back in place. Upon completion, the USR operator can start up the improved modular printing system 10 in a test mode so as to confirm that the guide is not getting hot, eg from excessive friction. If not, the optimized modular printing system 10 can be placed in or returned to service. If the temperature of work guide piece 98 increases excessively during the test, the operator or USR service personnel may repeat one or more of the procedures as needed and retest.
    [0050] When the transfer belt 18 and rollers 16 are considered to be both parallel and properly tensioned, the USR operator may preferably dial 112 (Fig. 5), both the transfer belt 18 and the guide of the work piece 98, and then rotatably moving, i.e. before, the transfer belt 18 from one part of the system to another part of the system, for example at opposite ends 86, 88, at which time the location of the mark 112 can be determined and compared to the expected location, whereby the difference is calculated, for example, in millimeters. The calculated difference gives an indication as to whether there is any slippage in transfer belt 18, ie to confirm that there is no problem with the installation during operation.
    [0051] After installation, the owner or operator USR will normally not need to reset the tolerance, as rollers 16 and transfer belt 18 are dimensionally stable, such as for the expected life of transfer belt 18, for example, which can have an operating life of up to or greater than about two years.
    [0052] An exemplary printing operation is also seen in Figure 2, in which a print job 66, as received from a remote terminal, for example a designer or artist, arrives at a host computer 62, which may be associated with controller 20. In some embodiments of the system, print job 66 comprises a print job 66 in tagged image file format (TIFF).
    [0053] The host computer 62 then normally produces, i.e. RIPs, an image file tracker of the received print file 66, whereby the host computer 62 makes appropriate separations 64, which are assigned to one or more channels 68, eg 68a-68h, as far as necessary to print the image. Each of the channels 68, eg 68a-68h, are sent to a corresponding server computer or processor 70, eg 70a-70h, associated with each print bar 42, eg 42a-42h, for printing respective colors or other coatings on the WP workpieces. The server computers or processors 70 may be independent or integrated with the corresponding print bars 42. The different print bars 42, e.g. 42a-42h, are controlled by the respective server computers 70, wherein each auxiliary computer 70, e.g. , 70a, operates in conjunction with a respective print bar 42, e.g., 42a, i.e. a channel for each server computer 70.
    [0054] While the host computer 62 is doing the RIP, the printing system 10 is typically configured to work with the graphics that are uploaded to the servers 70. When each of the server computers 70 has the information for its respective bar At print 42, the server computer 70 is connected, for example, via an HPC card, to each of the print heads 82 (Fig. 3, Fig. 6, Fig. 15). In some embodiments of printing system 10, each printhead 82 has a dedicated HPC board for local processing.
    [0055] Controller 20 can be preferably configured, via programmed processors 22, eg 22a-22e, to provide integral printer management capabilities, and/or to optimize printer capabilities across all of its options. Controller 20 and processors 22 may preferably be remotely upgradeable, such as via communications link 46, which allows the USR operator to handle all elements quickly and intuitively.
    [0056] The improved modular printing system 10 may preferably comprise additional features, such as any of a tone adjustment system (TAS), calculated linearization capabilities, and/or calculated ink consumption capabilities. The Tone Adjustment System (TAS) can preferably be based on an intuitive interface, as shown 36, which guides the USR user through the process of studying and applying changes in tone or intensity, if applied to a model. This feature allows for adjustments or variations to existing models in the Enhanced Modular Printing System 10, without the use of additional external software, or extensive knowledge of color management.
    [0057] The electronic design of the improved modular printing system 10 may preferably be based on the distribution of modular components, thus facilitating future improvements and allowing complete accessibility. The electronics of the improved modular printing system 10 offer high performance, using the main computer 62 to upload image files 66 and server computers 70 that manage the printing of the files 66. The result is increased graphic variability and manufacturing without to stop. The improved electronic design makes it possible to choose between several printing options, and simultaneously use different print heads 82 in the same printing system 10, for example some for decoration and for applying other effects such as, but not limited to, effects in three dimensions (3D).
    [0058] Figure 3 is a detailed partial perspective view of an exemplary conveyor assembly 80 14 associated with an improved modular printing system 10, wherein the transfer belt moves in a displacement direction 32 with respect to an X axis. , 92X, a Y axis, 92Y and a Z axis, 92z. The exemplary print bars 42 seen in Figure 3 are fixedly locked with respect to chassis 12, such as through fastening structures 150 (Fig. 6-15), such as comprising a fixed portion 162 (FIG. 7) and a movable portion 164 (FIG. 7), which are configured to be lock-alignable and with respect to each other, and may be located on one or both sides 152a, 152b (Fig. 6, Fig. 7) of chassis 12, such as through, but not limited to, fixed anchor plates 99.
    [0059] Figure 4 is a plan view 100 of an exemplary improved modular printing system 10, wherein each of the print bars 42 is aligned at a position 103a and locked with respect to chassis 12.
    [0060] Figure 5 is a plan view 120 of an exemplary modular reinforcement of the printing system 10, in which one of the print bars 42, eg 42d, is located in a release position 103c, relative to the chassis 12 , as well as with respect to a print bar housing 124, and where the other print bars 42 are affixed aligned 103a with respect to their respective print bar guides associated with chassis 12. The plurality of print bars 42, eg 42a-42h, seen in Figure 4 and Figure 5 comprises separate, i.e. independent, modular print bars 42.
    [0061] Figure 6 is an end view 140 of an exemplary improved modular printing system 10, where one of the print bars 42 is located in an aligned and locked position 103a with respect to chassis 12. Figure 7 is a view of end 160 of an exemplary improved modular printing system 10, wherein one of the print bars 42, eg 42d (Fig. 5), is located in a release position 103c, with respect to chassis 12. When a print bar 42 is located in a release position 103c, the print bar 42 released can be fully accessed, such as to perform both daily operations and/or preventive maintenance work, such as with a maintenance system 156. Also, the printer 10 may preferably continue to function while specific tasks are performed on one or more of the print bars 42. As seen in Figure 6 and Figure 7, each of the print bars 42 may comprise give a frame of print bars 154.
    [0062] The improved print bar 42 seen in Figure 6 and Figure 7 therefore provides sliding movement for removal and installation to provide easy access to both the printhead frame 154 and the head maintenance system 156 associated with each print bar 42. Similarly, the improved modular print system 10 has separate print bars 42 for different colors of ink or other coatings 90, such that each color or coating corresponds to a separate printhead frame. , head maintenance tray, and vacuum anti-vacuum system 302 (FIG. 14).
    [0063] Some exemplary embodiments of the improved modular printing system 10 comprise a ceramic decoration ceramic Model C3 multipurpose printer, eg, CRETAPRINTER® or CRETACOMPAT®, available from EFI Cretaprint, Inc., of Foster City, CA, USA, which are currently configured to hold up to eight 42 print bars, eg 42a-42h, for special finishing and decoration purposes. Such modular printing systems 10 are highly configurable, and provide precise transport of WP workpieces, for example, up to 0.3mm accuracy, in colors that are separated up to 2800mm.
    [0064] Embodiments of the reinforced modular printing system 10 that are configured to hold a plurality of print bars 42 may preferably provide a large number of configuration options to better satisfy the requirements of the USR user. For example, the USR user can easily configure the enhanced modular 10 printing systems based on • the number of decoration bars 42; • in the number of special application bars 42; • in print width 104 (Fig. 4); • print characteristics suitable for any of the resolution, speed and ink discharge conditions; and / or • in the print direction.
    [0065] In some embodiments of the enhanced modular printing system 10, the USR user can initially select a configuration that best suits their current production needs and then, if necessary or desired, the USR user can expand the system 10, for example, by adding and/or replacing print bars 42, and/or by adding a specified print width 104.
    [0066] For example, in some embodiments of the CRETAPRINTER® 10 system, the print width 104 can be increased in multiples of 70mm up to a maximum of 1120 mm, while in some embodiments of the CRETACOMPAT® 10 system, the print width 104 can be increased in multiples of 70mm up to a maximum of 700mm.
    [0067] Once the setting has been chosen, this can be increased (or decreased as desired or required) both in print width 104 and in the number of bars 42, as shown: • 3 print bars 42, per example, for trichromatic ceramic printing; • 4 print bars 42, eg for four-colour ceramic printing; • 6 print bars 42, eg for hexachromatic ceramic printing; and / or • 8 printing bars 42, eg for double-coloured ceramic printing.
    [0068] In this way, a USR ceramics manufacturer can select a configuration that best suits their current production needs, and can then optimize the enhanced modular printing system 10 as their needs change, thereby maximizing the value of their initial investment.
    [0069] In some embodiments of the enhanced modular printing system 10, a USR user may preferentially print four to eight colors, each with an associated print bar 42, to decorate WP ceramic tiles. Within a given improved modular printing system 10, printheads 82 may preferably be supplied by one or more manufacturers, for example, Toshiba, Xaar, Fuji / Dimatix, and/or Konica / Minolta. Although different print bars 42 may include print heads 82 from different manufacturers, the print heads 82 within a print bar 42, for example 42a, are generally configured with a plurality of print heads 82 from the same manufacturer, wherein the print heads 82 are configured as an installation from a chosen manufacturer within the corresponding print bar 42.
    [0070] In some exemplary embodiments of system 10, the USR user can preferably designate zero to three print bars 42 for generating applications other than decoration. In embodiments of the current system, printheads 82 for purposes other than decoration comprise Fuji-Dimatix printheads, available from Fuji Photo Film Co., Ltd. Corp, of Tokyo, Japan.
    [0071] In some embodiments, the improved modular printing system 10 may preferably be configured with electronics and software to operate with different print heads 82 in the same system 10. For example, one or more of the print bars 42 can be configured with printheads 82, eg 42a-42f, per print, while one or more of the other print bars 42, eg 42g-42h, can be configured with printheads 82 having a strong discharge of paint, for example, to apply special coatings, such as, but not limited to, preparations for coatings, enamels, colored clear or translucent coatings, and/or protective coatings. Some embodiments of the improved modular printing system 10 can preferably be configured to apply at least two different glazes on the same WP ceramic tile so as to obtain different effects depending on where the different glazes are applied.
    [0072] The enhanced modular printing system 10 can therefore be configured or reconfigured to meet any of a factory's current or future needs. For example, the compact modular chassis 12 allows the enhanced system 10 to be quickly and easily installed on site, and also easily allows for subsequent upgrades as needed or desired. Thus, the USR user can easily maintain and/or upgrade the enhanced modular printing system 10. For embodiments of the enhanced modular printing system 10 that are configured to print on WP ceramics, the systems 10 can easily be configured to apply a wide variety of ceramic and special effects decorations, while fitting within the physical space of a factory.
    [0073] Some embodiments of the improved modular printing system 10 may comprise one or more symmetrical components, such as, but not limited to, chassis 12, print bars 42, or electrical and/associated switchgear, as easily configured for any Required belt direction 32, wherein the WP workpieces, eg ceramic tiles 42, can move 32 in any direction, eg with respect to the X axis 92x. For example, in the improved modular printing system 10 seen in Figure 4, the transfer belt 32 can be configured to move the ceramic tiles 32 WP from right to left, or alternatively, from left to right, such as. as needed or desired by the USR user.
    [0074] Some embodiments of the improved modular printing system 10 may preferably be configured to protect the print heads 82 associated with one or more of the print bars 42. For example, the exemplary print bar 42 seen in Figure 15 it further comprises a height sensor 332, for example a dual laser sensor-332 at the input of the print bar 42, which is configured to detect both the position and thickness of each workpiece WP. The height sensor 332 is configured to send a signal to a mechanism 336 that is configured to move at least a portion of the print bar 42 vertically 338. The configuration can preferably be used to: • protect a print bar 42, when not ejecting ink; or • move at least a portion of the print bar 42 vertically to fit the print bar 42 with the detected height of a WP workpiece.
    [0075] During these operations, print bars 42 that are not currently used for applying any decoration or special effect can preferably be configured to remain above and protected.
    [0076] Figure 6 also shows an exemplary drive mechanism 26, end roller 16 and conveyor assembly 14 for an improved modular printing system 10 of exemplary ceramic tile. Partial cross-sectional view of transfer belt 18 of Figure 3 reveals that conveyor assembly 14 typically comprises a support transfer belt 94 located between rollers 16, such as to support the weight of one or more workpieces. WP, for example, WP ceramic tiles.
    [0077] In some embodiments of the improved modular printing system 10, the drive motor 142 is preferably chosen to reduce or eliminate electrical noise, for example, radio frequency (RF) noise, which may otherwise mode to interfere with the operation of electronic equipment associated with the improved modular printing system 10. For example, drive motor 142 may comprise a preferably brushless motor 142 to provide accurate continuous operation. Thus, encoder 28 (Fig. 1) may preferably be chosen to provide accurate continuous operation of drive motor 142, while reducing or eliminating RF noise.
    [0078] The drive motor 142 can preferably be specified for a wide variety of applications so as to provide stepwise, i.e. start and stop, motion, or continuous motion. For example, in the exemplary improved modular printing system 10 described herein, such as for printing on WP ceramic tiles, drive mechanism 26 is typically required for transporting large numbers of WP ceramic tiles, which are generally large. and heavy. A current embodiment of the improved modular printing system 10 is configured to move ceramic tiles WP at a constant speed, where the maximum speed of the conveyor belt 18 is about five meters per minute. As such, drive mechanism 26, comprising drive motor 142 and transfer unit 144, are rated to controllably bring transfer belt 18 and workpieces 18 up to speed, maintaining a constant speed over a cycle of rated operation, for example, up to 100 percent of full capacity and bringing system 10 to a halt.
    [0079] In addition to the rated power for the drive motor 142 and the transfer drive 144 to take a line to maintain constant speed and that speed, it should be understood that the system 10 and combined mass of a large number of WP ceramic tiles, for example, up to about 500 kg at a time typically result in significant inertia, with which drive mechanism 26, transfer belt 18, and other components associated with conveyor assembly 14 are configured. to manipulate, such as for starting, constant running, and stopping.
    [0080] In addition to the performance requirements for the drive mechanism 26, the transfer belt 18 is also configured to be suitably strong in all operating conditions, preventing deformation or bending. Likewise, all other hardware related to the enhanced modular printing system 10 is configured to meet all operating requirements.
    [0081] While the exemplary improved modular printing system 10 disclosed herein may preferably be configured to operate at a constant belt speed, it is to be understood that the improved modular printing system 10 may be suitably configured for other types of operations, such as for systems that may require staggered operation, in which the drive motor 142 may preferably be configured to turn on and off. In such applications, the drive motor 142 can preferably be controlled with pulse width modulation (PWM).
    [0082] Some embodiments of the improved modular printing system 10 are powered via an uninterruptible power supply (UPS), wherein the enhanced modular printing system 10 isolates the external current, as for any of the controllers 20, sensors, bars electronic printers, associated computers, memories, or other sensitive electronic devices. The operation of the drive mechanism 26 is controlled via the controller 20, such as by any start, run and stop of the conveyor facility 14.
    [0083] The use of uninterruptible power supply (UPS) helps to avoid variations in voltage spikes and maintains power at a consistent level. Print system 10 can therefore move at a constant rate, independent of input feed fluctuations, whereby print system 10 can coincide with electronic print heads 82. Thus, just as in a customer facility , after loss of input power, the UPS can preferably be configured to provide a sufficient time, such as turning off the production machine, for example, to avoid problems with electronic components, computers and heads.
    [0084] Print bar fastening systems and associated structures. Figure 8 is a schematic view of an exemplary print bar fastening structure 180 150 in a release position 183c, which corresponds to a release position 103c of a print bar 42 relative to a print bar housing 124 Figure 9 is a schematic view of an exemplary print bar 200 fastening structure 150 in an aligned position 183b, corresponding to an aligned position 103b of a print bar 42 with respect to a print bar guide 124. Figure 10 is a schematic view 220 of an exemplary print attachment structure 150 in an aligned and locked position 183a, corresponding to a locking position 103a of a print bar 42 relative to a print bar guide 124.
    [0085] The exemplary print bar 42 seen in Figure 8 comprises one or more alignment pins 184 having a tapered profile 185, wherein the alignment pins 184 extend axially from the print bar 42, i.e. perpendicular to the longitudinal axis, eg perpendicular to the X axis, 92X, of the transfer belt 18. The exemplary alignment pins 184 seen in Figure 8 are affixed to and extend from a print bar 186. The exemplary attachment plate print bar 42 seen in Figure 8 is movable transversely 202 (FIG. 9), 208 (FIG. 9) with respect to chassis 12, for example, parallel to a Y axis, 92Y, such as by means of movement of one or further slider mechanisms 122, which may preferably be mounted to a print bar frame 154 associated with each corresponding print bar 42. A lock mechanism 194 is also mounted on print bar 42, and comprises a pin mechanism 198 and an actuator 196, for example, a pneumatic actuator or an electric actuator 196 196, where the pin mechanism 198 is movable 224 (Fig. 10) between a released position and a locked position, in response to movement 262 (FIG. 12) of actuator 196. The exemplary actuator 196 seen in Figure 8 is pivotally connected to print bar 42, such as through a pivot of assembly 198. Fixed portion 162 of the exemplary fixture structure 150 seen in Figure 8 comprises a latch mechanism 192 that is fixedly connected with respect to chassis 12, where latch mechanism 192 is configured to receive at least a portion of the latch mechanism. pin 198.
    [0086] As seen in Figure 9, the print bar 42 is slidably movable 202 relative to the chassis 12. The tapered profile 185 of the AIDS alignment pins 184 in alignment between the alignment pins 184 and the holes 182 having associated shafts 282 (FIG. 13), such that the alignment pins 184 are configured to easily move into the corresponding alignment holes 182. While the tapered profile 185 shown in Figure 8 illustrates an exemplary profile 185 that can be used to align the alignment pins 184 and the alignment holes 182, it is to be understood that other profiles 185, for example tapered or rounded profiles 185, can preferably be used to ensure accuracy and repeatability of the sliding movement of the print bars 42 with respect to a corresponding print compartment 124.
    [0087] Once the alignment of pins 184 enters the alignment holes 182, the print bar 42 is configured to reach an aligned and lockable position 103b, where the print bar 42 is accurately positioned within a corresponding print compartment 124, such as with respect to an X axis, 92X, a Y axis, 92Y and a Z axis, 92Z. The an aligned and lockable position 103b seen in Figure 9 corresponds to a position where a portion of the print bar 42, e.g. print bar clamp plate 186, contacts a fixed part of the print system 10, for example, a fixed fixture plate 99.
    [0088] When print bar 42 is in the aligned and lockable position 103b with respect to chassis 12, pin mechanism 198 is lockable relative to latch mechanism 192. For example, the exemplary actuator 196, seen in Figure 10, is configured, such as in response to manual or automated control 22, to controllably move pin mechanism 198 relative to latch mechanism 192 to precisely lock print bar 42 for printing a corresponding guide 42.
    [0089] Similarly, from a locked position 183a, the exemplary actuator 196 seen in Figure 10 is configured, such as in response to a manual or automated control 22, to controllably move the pin mechanism 198 with respect to the latch mechanism 192, for unlocking the print bar 42 with respect to its corresponding print guide 42, wherein the print bar 42 can be moved 208 (FIG. 9) to a released position 183c (Fig. 8).
    [0090] Figure 11 is a first perspective view 240 of an exemplary locking mechanism 150. Figure 12 is a second perspective view 260 of an exemplary locking mechanism 150. Figure 13 is a third perspective view 280 of an exemplary locking mechanism 150. Since registration of the print bars 42, eg 42a-42h, with respect to the print system 10 and for the other print bars 42 is critical, the securing mechanisms 150 are configured to accurately lock down the print bars 42 in the respective print guides 124, while simultaneously providing access to the print bars 42, as needed or desired. Each of the print bars 42 may preferably have at least two locking and aligning mechanisms 150, such as on opposite sides 152a, 152b of the chassis 12, where the print bars 42 are precisely compressed on the other side. of the transfer belt 18, to provide accurate registration of the print heads 82 with respect to the printing system 10.
    [0091] The alignment and locking mechanisms 150 therefore allow the print bars 42 to be easily removed, for maintenance, and returned for service. Once installed in-line with respect to the printing system 10, the locking mechanisms 150 can be easily actuated, such as pneumatically or electrically, to precisely lock the print bars 42 to the respective print compartments 124, so that the bars prints 42 can be put back into service, while inherently maintaining print quality to print bars 42.

Such WP ceramic coatings enter the printing system 10 at elevated temperatures, for example, around 150 degrees Celsius. WP ceramic tiles are generally processed with water and/or steam, such that as with tiles entering the printing system 10, which is commonly residual moisture G which, if not removed, can be problematic for subsequent operations. for example, the delivery of jetting 84 of oil-based ink 90. Thus, the moisture L can continue to be degassed from the WP ceramic tiles as they are transported on the transfer belt 18, which can cause further problems .

As seen in Figure 15, a WP workpiece entering the print zone of the print bar 42 may have residual moisture G in or around the WP workpiece. The first moisture removal chamber 304a, positioned upstream of the print bar 42, is configured to remove moisture G prior to ink delivery 84 (FIG. 3) from the printheads 82. A second ink removal chamber moisture 304b, positioned downstream of print bar 42, is configured to remove moisture L and/or other ink delivery contaminants 84 after print heads 82, such as prior to the arrival of part 42 on one or more print bars. later printing 42.

Each of the moisture removal pressure chambers 302 is connected, for example, 312, 316 (FIG. 14) to provide conduits for removing moisture L, such as in a common collector 318 which is connected to a vacuum source 320, whereby moisture G and other contaminants can be effectively removed from the printing environment 10. As described above, the moisture removal chamber 304 can pre preferably be configured to provide a desired pressure differential, i.e. consistent in region 322, to adequately remove moisture G and other impurities.

For example, the height 362p of the improved vacuum pressure chamber 304 in the far end 308p is less than height 362a of improved vacuum pressure chamber 304 at near end 308a. Likewise, the width 364 of the improved vacuum pressure chamber 304 can be configured throughout the suction region 322. While the exemplary improved moisture removal chamber 304 seen in Figure 17, is shown generally as a planar conduit, for example, having a rectangular cross section at one or more points across the suction region 322, it is to be understood that other cross sections may be provided, such as, but not limited to, other polygonal or curved surfaces and/or cross sections.
