Description
- The present application claims the benefit of priority under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 63/348,445, entitled INKJET MODULE WITH PRINTHEAD NEST ASSEMBLY, filed Jun. 2, 2022; U.S. Provisional Application No. 63/348,449, entitled PRINTING UNIT WITH TANDEM INKJET MODULES, filed Jun. 2, 2022; U.S. Provisional Application No. 63/377,240, entitled PRINTING UNIT WITH TANDEM INKJET MODULES, filed Sep. 27, 2022; and U.S. Provisional Application No. 63/476,671, entitled PRINTING UNIT WITH TANDEM INKJET MODULES, filed Dec. 22, 2022, the contents of each of which are hereby incorporated by reference in their entirety for all purposes.
- The present application is related to U.S. application Ser. No. ______ (Attorney Docket No. FXB027US), entitled INK DELIVERY SYSTEM WITH FILTER PROTECTION, filed on even date herewith, the contents of which is hereby incorporated by reference in its entirety for all purposes. This related application has been identified by its Attorney Docket No., which will be substituted with a corresponding US application No., once allotted.
- This invention relates to inkjet modules for use in modular single pass print systems. It has been developed primarily for facilitating printhead replacement in a robust inkjet module, whilst ensuring secure datuming of the printhead.
- Inkjet printers employing Memjet® page wide technology are commercially available for a number of different printing applications, including desktop printers, digital inkjet presses and wide format printers. Memjet® printers typically comprise one or more stationary inkjet printhead cartridges having a length of at least 200 mm, which are user replaceable. For example, a desktop label printer comprises a single user-replaceable multi-colored printhead cartridge, a high-speed inkjet press comprises a plurality of user-replaceable monochrome printhead cartridges aligned along a media feed direction, and a wide format printer comprises a plurality of user-replaceable printhead cartridges in a staggered overlapping arrangement so as to span across a wide format page width.
- Analogue printing presses are conventionally used for relatively long print runs in which the cost of producing dedicated printing plates is economically feasible. Increasingly, industrial print systems use single-pass digital inkjet printing for relatively shorter print runs. Digital inkjet printing avoids the high set-up costs of producing printing plates and allows each print job to be tailored to a particular customer. Desirably, web feed systems for existing analogue print systems should be adaptable to enable ‘drop-in’ inkjet modules in place of, for example, offset printing stations. It is therefore desirable for inkjet modules to occupy minimal space with respect to a media feed direction, whilst allowing full color printing at high speeds with optimum print quality.
- Inkjet printheads need to be replaced periodically and it would be desirable to enable printhead replacement with a high degree of reliability and accuracy so as to minimize alignment errors, especially in print systems having a plurality of printheads aligned along a media path. It would further be desirable to protect sensitive electronics, delivering power and data to the printhead, from ink mist during printing.
- U.S. Pat. No. 10,293,609 describes a full color page wide printhead having two rows of chips receiving ink from a common manifold.
- U.S. Pat. No. 10,967,638 describes a print module having a pivotable printhead carrier for printhead removal and replacement via sliding longitudinal insertion of the printhead through an access opening at one end of the printhead carrier.
- U.S. Pat. No. 10,647,137 (the contents of which are incorporated herein by reference) describes a print module which is liftable upwards from a sleeve for printhead removal and replacement.
- In one aspect, there is provided a printhead nest assembly for facilitating printhead replacement, said printhead nest assembly comprising: a nest configured for detachable fastening to a printhead carrier; and a replaceable printhead nestably secured within the nest, the nest enveloping all sides of the printhead, wherein the nest is configurable in open and closed positions, the nest allowing removal of the printhead therefrom only in the open position and only when the printhead nest assembly is detached from the printhead carrier.
- The printhead nest assembly, which is typically mounted to an underside of the printhead carrier, enables users to replace printheads in the inkjet module without requiring overhead access to the printhead carrier. The printhead nest assembly provides a convenient unit for replacing printheads, firstly, within the nest and thence within the inkjet module. The printhead is removable from the nest only when the printhead nest assembly is detached from the printhead carrier (i.e. wholly separated from the printhead carrier about all sides, such that the printhead nest assembly can be handled by a user as a discrete unit). Furthermore, the printhead nest assembly provides accurate and repeatable datuming of the printhead, as well as protection of sensitive electronic components from ink mist, as will be described in further detail below.
- As used herein, the term “inkjet module” is taken to mean an assembly of components, which includes an inkjet printhead, such as an elongate printhead configured for single-pass printing (known in the art as a “page wide” or “line head” printhead). The inkjet module typically also includes maintenance components and/or ink delivery components to provide a fully integrated inkjet system. The inkjet module may itself be a component of a modular print system, which may comprise, for example, a plurality of inkjet modules. Inkjet modules may be, for example, aligned along a media feed direction for very high-speed printing, or a plurality of inkjet modules may be positioned in a staggered overlapping arrangement across a media feed path for wide-format printing.
- As used herein, the term “ink” is taken to mean any printing fluid, which may be printed from an inkjet printhead. The ink may or may not contain a colorant. Accordingly, the term “ink” may include conventional dye-based or pigment-based inks, infrared inks, fixatives (e.g. pre-coats and finishers), 3D printing fluids, solar inks, and the like.
- As used herein, the term “mounted” includes both direct mounting and indirect mounting via an intervening part.
- Specific embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings, in which:
-
FIG. 1 is a top front perspective of an inkjet module in a printhead lowered position; -
FIG. 2 is a bottom rear perspective of the inkjet module shown inFIG. 1 ; -
FIG. 3 is a top front perspective the inkjet module is a printhead raised position; -
FIG. 4 is a perspective of part of the inkjet module with a bracket shown in transparency to reveal a sleeve bushing; -
FIG. 5 shows part of a printhead carrier with a printhead nest assembly removed; -
FIG. 6 is a top perspective of the inkjet module showing the lift mechanism; -
FIG. 7 shows the inkjet module with an end wall removed to reveal a capping assembly and cap cover; -
FIGS. 8A-8C are side views of engagement between a cam guide of the capping assembly with a rocker arm of the cap cover; -
FIG. 9 is top perspective of a printhead nest assembly in a closed position; -
FIG. 10 is a top perspective of the printhead nest assembly in an open position; -
FIG. 11 is a bottom perspective of the printhead nest assembly shown inFIG. 8 ; -
FIG. 12 is a perspective of a printhead being inserted into a nest; -
FIG. 13 shows the nest in isolation in an open position; and -
FIG. 14 is a plan view of part of the nest. -
FIGS. 1 to 7 show an integratedinkjet module 1 suitable for use in industrial printing systems. Theinkjet module 1 is a self-contained unit comprising anelongate printhead 3 configured for single-pass printing, as well as requisite components for capping, wiping and delivering ink, power and data to the printhead in a compact, fully integrated assembly. Theprinthead 3 contains two rows ofbutting print chips 5 mounted on a singular uniform ink manifold, as described in U.S. Pat. Nos. 10,293,609 and 10,967,638, the contents of which are incorporated herein by reference. - The
inkjet module 1 may be used singly or as a modular component of a single pass printing system comprising a plurality of such inkjet modules. For example, inkjet modules may be fully aligned in a stacked arrangement along a media feed path or positioned in a staggered overlapping arrangement across a wider media feed path. Hence, theintegrated inkjet module 1 allows facile construction of single pass printing systems in a versatile and scalable manner. By way of example only, Applicant's co-filed U.S. application Ser. No. ______ (Attorney Docket No. FXB029US) entitled “PRINTING UNIT WITH TANDEM INKJET MODULES” describes a high-speed industrial printing unit incorporating an opposing pair ofsuch inkjet modules 1. - The
inkjet module 1 comprises achassis 10 having anelongate base plate 12 with arear wall 14 and a pair ofopposite end walls 16 extending upwards from the base plate. Aside from providing thechassis 10 with structural rigidity, therear wall 14 also serves as a support for mounting various fluidic components (e.g.,pinch valves 15 and pumps 17) and electronic components (e.g., module controller PCB 19) on both its front and rear faces. Openings in therear wall 14 allow fluidic connections from the rear face of theinkjet module 1, without requiring overhead access. - The
base plate 12 is generally C-shaped having a pair oftransverse arms 18 extending from opposite ends of alongitudinal base member 20 along a nominal x-axis of theinkjet module 1. An openlongitudinal slot 22 is defined between thetransverse arms 18 at a front side of theinkjet module 1. The openlongitudinal slot 22 extends parallel with a longitudinal axis along a nominal y-axis of theinkjet module 1 and is configured for receiving theelongate printhead 3. Thus, theprinthead 3 is asymmetrically positioned in theinkjet module 1 towards a front side thereof, allowing proximal positioning of printheads from oppositely oriented inkjet modules. Theprinthead 3 may be either lowered through theslot 22 for printing or raised above thebase plate 12 for maintenance (e.g., capping and/or wiping). - A pair of
posts 24 extend upwards from thetransverse arms 18 of thebase plate 12 at opposite ends of the openlongitudinal slot 22. Eachpost 24 is anchored to thebase plate 12 at a lower end thereof and secured to arespective end wall 16 at an upper end thereof. A pair ofbrackets 26 are slidably engaged with theposts 24 viarespective sleeve bushings 28 inserted in each bracket. Eachsleeve bushing 28 is slidably movable relative to arespective post 24 allowing vertical linear movement of thebrackets 26 towards and away from thebase plate 12 along a nominal z-axis of theinkjet module 1. Aflanged portion 29 at a lower end of eachsleeve bushing 28 is fastened to eachbracket 26 and datums its respective bracket against thebase plate 12 in the printhead lowered position (FIG. 1 ). - An
elongate printhead carrier 30 is fixedly supported between thebrackets 26 and is linearly slidably movable with the brackets. Theprinthead carrier 30 comprises spaced apart front andrear carrier plates 32 interconnecting thebrackets 26 and defining acavity 34 therebetween for housing electronic components supplying power and data to theprinthead 3. Abrace 38 interconnects upper parts of thecarrier plates 32, while a pair of datum blocks 40 interconnect lower parts of the carrier plates. The datum blocks 40 are positioned at opposite longitudinal ends of theprinthead carrier 30 towardsrespective brackets 26. The bracedprinthead carrier 30, in combination with thesleeve bushings 28, posts 24 andchassis 10 provide a robust support structure for theprinthead 3. Theprinthead 3 is itself secured within acomplementary nest 102 to form a printhead nest assembly 100 (seeFIG. 9 ), which is mounted to the datum blocks 40 viascrew fasteners 42 engaged with the nest. - The
printhead 3 is linearly slidably movable towards and away from thebase plate 12 between a printing position (FIG. 1 ) and a maintenance position (FIG. 3 ) by means of a lift mechanism operatively connected to eachbracket 26. As best shown inFIG. 6 , the lift mechanism comprises a pair oflead screws 44 rotatably mounted to thebase plate 12 and extending upwards parallel with theposts 24. Eachlead screw 44 hasrespective lead nut 46 fixedly connected to a respective bracket via alead nut connector 48. The lead screws 44 are rotatable by means of an interconnecting pulley belt assembly operatively 50 connected to acommon lift motor 52. Accordingly, theprinthead 3 may be moved between raised and lowered positions by actuation of thelift motor 52, which rotates the leads screws 44 simultaneously via thepulley belt assembly 50, thereby lifting or lowering theprinthead carrier 30 connected to thelead nuts 46 via thebrackets 26. - As best shown in
FIG. 3 , theinkjet module 1 comprises awiper carriage 54, having amicrofiber wiping web 56, parked at one end of thelongitudinal slot 22. In the printhead raised position, thewiper carriage 54 is movable longitudinally along the length ofprinthead 3 by means of awiper movement mechanism 57 mounted on alongitudinal wiper support 55 in order to wipe ink and debris from the printhead face. In the printhead lowered position (FIG. 1 ), one of thebrackets 26, having abracket roof 27 and bracket sidewalls 29, shields thewiper carriage 54. Thus, thebracket roof 27 and bracket sidewalls 29 provide at least some protection from ink mist and/or debris that may contaminate thewiper carriage 54 via an open front face of theinkjet module 1 during printing. - The
inkjet module 1 further comprises a cappingassembly 60 which is parked towards therear wall 14 and linearly slidably movable towards and away from theprinthead 3 along transverse capper rails 62 by means of rack-and-pinion mechanism 64. The capping assembly comprises 60 acapper base 66 slidably engaged with the capper rails 62, aperimeter printhead capper 68 mounted on the capper base, and cam guides 70 mounted fast with the capper base at opposite ends of the printhead capper. In its parked (covered) position shown inFIG. 3 , theprinthead capper 68 is covered with acap cover 72 pivotally mounted to therear wall 14 of thechassis 10. Thecap cover 72 takes the form of a rigid plate, which seals against aperimeter seal 69 of theprinthead capper 68 and maintains a humid environment within the printhead capper whenever the printhead capper is not being used for capping theprinthead 3. Thewiper movement mechanism 57 is mounted on thewiper support 55, which is fixedly attached to therear wall 14 directly above thecap cover 72. - For printhead capping, the capping
assembly 60 is laterally moved away from thecap cover 72 into alignment with theprinthead 3, and the printhead is gently lowered onto theprinthead capper 68 into a capped position using the lift mechanism. With the printhead raised, transverse movement of the cappingassembly 60 back towards therear wall 14 engages arear cam surface 73 of the cam guides 70 with anengagement node 77 ofrespective rocker arms 74 at each end of the cap cover. Therocker arms 74 are pivotally mounted to therear wall 14 and allow thecap cover 72 to pivot upwards on engagement with the cam guides 70, thereby enabling the cappingassembly 60 to slidingly traverse under the cap cover. Once the cappingassembly 60 has reached its rearmost parked position, thecap cover 72 pivots back downwards, by virtue of the profile of the cam guides 70 androcker arms 74, into the covered position in which theprinthead capper 68 is covered by the cap cover. -
FIG. 8A shows therear cam surface 73 of thecam guide 70 engaged with anengagement node 77 of therocker arm 74 as the cappingassembly 60 approaches therear wall 14.FIG. 8B shows therocker arm 73 pivoted upwards as the capping assembly transitions towards its covered position.FIG. 8C shows the cappingassembly 60 in its rearmost parked position with therocker arm 74 pivoted back into a horizontal plane and theprinthead capper 68 covered by thecap cover 72. For printhead capping, the cappingassembly 60 slides from its parked position shown inFIG. 8C towards theprinthead 3. Afront cam surface 75 of thecam guide 70 engages with theengagement node 77 of therocker arm 74 in order to pivot the rocker arm upwards and allow sliding movement of the capping assembly towards theprinthead 3. - As foreshadowed above, and referring now to
FIGS. 5 and 6 , theprinthead carrier 30 defines acavity 34 between front andrear plates 32 thereof. Thecavity 34 houses asupply module 80, which includes front andrear PCBs 82 for supplying power and/or data to theprinthead 3. A coolingfan 84 is positioned between thePCBs 82 for cooling electronic components with cool air drawn into thecavity 34 from an upper side of theprinthead carrier 30. Thebrace 38, which defines a roof portion of theprinthead carrier 30, has an open truss structure, which allows circulation of cool air through thecavity 34 and between thePCBs 82. Thesupply module 80 further comprisesink couplings 86 for engagement withcomplementary ink ports 88 at opposite ends of theprinthead 3. Thesupply module 80 forms ink and electrical connections with theprinthead 3 upon installation of the printhead (secured in its printhead nest assembly 100) onto theprinthead carrier 30, as will be explained in more detail below. -
FIGS. 9 and 10 show theprinthead nest assembly 100 in isolation. As shown inFIG. 9 , the nest is in its closed position with theprinthead 3 nestably secured within thenest 102 and enveloped about all sides by the nest. InFIG. 10 , thenest 102 is in its open position, which allows removal of theprinthead 3 from the nest, but only when theprinthead nest assembly 100 is fully detached from theprinthead carrier 30. In other words, theprinthead 3 must be united with thenest 102 to form theprinthead nest assembly 100 before the printhead (e.g. a replacement printhead) can be installed in theinkjet module 1 by fastening thenest 102 to theprinthead carrier 30. - The
nest 102 is configured for detachable fastening to theprinthead carrier 30 via the pair ofscrew fasteners 42, which extend vertically through a height of theprinthead carrier 30. Eachscrew fastener 42 has ascrew lever 43 at one end which is user-accessible fromabove printhead carrier 30 and a screw tip projecting through a recessedopening 41 in a respective datum block 40 (FIG. 5 ). An upper surface of thenest 102 has a pair of datum pins 104 configured for complementary engagement with the recessedopenings 41 of the datum blocks 40. For installation of theprinthead nest assembly 100, eachscrew fastener 42 is screwed through ahollowed bore 105 of arespective datum pin 104 and into a threadednut insert 106 of thenest 102. Thus, theprinthead nest assembly 100 may be firmly secured to theprinthead carrier 30 with accurate datuming controlled by complementary datuming engagement between the datums pins 104 and the recessedopenings 41 in eachdatum block 40. Thenest 102 enables the use of relatively large datum pins 104, separate from theprinthead 3, for highly accurate and repeatable datuming between theprinthead carrier 30 and theprinthead nest assembly 100. - Screw fastening of the
printhead nest assembly 100 to theprinthead carrier 30 via the datum blocks 40 simultaneously forms ink and electrical connections between theprinthead 3 and thesupply module 80.Ink ports 88 at opposite ends of theprinthead 3 are raised into engagement withink connectors 86 of thesupply module 80. Likewise,electrical contacts 109 extending along opposite longitudinal sides of theprinthead 3 are brought into electrical contact withcomplementary PCB contacts 89 ofrespective PCBs 82 in thesupply module 80. Spring-biasedPCB mounting plates 90 of thesupply module 80 allow thePCBs 82 to flex laterally away from each other while theprinthead 3 is raised between the PCBs during installation of theprinthead nest assembly 100. The spring bias provides reliable electrical connections, while the requisite insertion force (for both the ink and electrical connections) is provided by thescrew fasteners 42, which are readily operable by the user using the screw levers 43. Accordingly, this arrangement obviates the movable supply assembly and two-staged ink and electrical connections, described in U.S. Pat. No. 10,967,638. - The
printhead nest assembly 100 may be fastened to theprinthead carrier 30 either in the printhead lowered (FIG. 1 ) or printhead raised position (FIG. 3 ), depending on whichever configuration is more accessible in a particular modular set-up of theinkjet module 1. As shown inFIG. 5 , theprinthead nest assembly 100 has been removed in the printhead lowered position. - Referring now to
FIGS. 10 and 13 , thenest 102 is configurable in a nest open position for printhead removal and insertion. Thenest 102 comprises first and second longitudinal side bars 110 and 112 extending parallel with opposite longitudinal sides of theprinthead 3 and a pair of shorter transverse end bars 114 interconnecting each end of the longitudinal side bars to define a rectangular (oblong)nest cavity 115. The firstlongitudinal side bar 110 and end bars are fixed 114, while the secondlongitudinal side bar 112 is movable towards and away from the first longitudinal side bar between the open and closed positions. - Each
end bar 114 has adowel pin 116 received the movable secondlongitudinal side bar 112. Sliding movement of the secondlongitudinal side bar 112 relative to the fixed dowel pins 116 provides relative linear movement of the second longitudinal side bar towards and away from the firstlongitudinal side bar 110. - Movement of the second longitudinal side bar is 112 effected by means of a locking mechanism, which configures the
nest 102 in either the closed or open positions. The locking mechanism comprises a pair of nest levers 120, each nest lever being pivotally attached to arespective end bar 114 and having a pivot axis perpendicular to a horizontal plane of the nest (i.e. parallel to a direction of droplet ejection from the printhead 3). Eachnest lever 120 defines acam slot 122 engaged with arespective follower pin 124 extending parallel with the pivot axis at opposite ends of the secondlongitudinal side bar 112. Pivoting motion of eachnest lever 120 away from itsrespective end bar 114 moves the secondlongitudinal side bar 112 linearly away from the firstlongitudinal side bar 110, by virtue of the cam engagement between thecam slots 122 and follower pins 124, in order to open thenest 102. Conversely, pivoting motion of eachnest lever 120 towards respective end bars 114 moves the secondlongitudinal side bar 112 linearly towards the firstlongitudinal side bar 110 to lock thenest 102 closed. Eachnest lever 120 has a finger-grip portion 126 at an opposite end from the pivot axis for user actuation of the locking mechanism. - In its closed position, the
nest 102 is configured to form an ink mist seal around theprinthead 3. The ink mist seal inhibits the ingress of ink mist into thesupply module 80 and thereby protects sensitive electronic circuitry on thePCBs 82 from fouling by any ink mist generated during printing. The ink mist seal comprises a pair of opposed first and secondlongitudinal lips 130 projecting inwardly towards the printhead from respective first and second longitudinal side bars 110 and 112. Eachlip 130 is engaged with alongitudinal edge region 132 of theprinthead 3 to form part of the ink mist seal. - To insert the
printhead 3 into thenest 102, the nest is firstly configured into its open position as shown inFIG. 13 . The printhead is then laterally guided into theopen nest cavity 115 at an oblique angle (FIG. 12 ) towards the firstlongitudinal side bar 110. A firstlongitudinal flange 134 at one side of theprinthead 3 is initially held at an angle below thelongitudinal lip 130 of the firstlongitudinal side bar 110 so as to overlap with the lip, and then the printhead is rotated about its longitudinal axis into a plane parallel with a plane of the nest.Printhead datums 136 at opposite ends ofprinthead 3 engage withcomplementary nest datums 138 to provide accurate and repeatable positioning of the printhead within the nest (FIG. 14 ). - With the
printhead 3 properly positioned inside the open nest (FIG. 10 ), the nest levers 120 are pivoted inwards so as to close the secondlongitudinal side bar 112 and lock thenest 102 into its closed position, thereby forming the locked printhead nest assembly 100 (FIG. 9 ). Closure of thenest 102 moves thelongitudinal lip 130 of the secondlongitudinal side bar 112 towards theprinthead 3 to complete the ink mist seal with eachlongitudinal flange 134 of the printhead positioned beneath and overlapping with its respective longitudinal lip. - The complete
printhead nest assembly 100 may then be secured to theprinthead carrier 30 using thescrew fasteners 42 as described above. For printhead removal, the reverse procedure is followed whereby theprinthead nest assembly 100 is detached from theprinthead carrier 30, the nest opened using the nest levers 120, and theprinthead 3 removed obliquely from theopen nest 102. - It will, of course, be appreciated that the present invention has been described by way of example only and that modifications of detail may be made within the scope of the invention, which is defined in the accompanying claims.
