Definitions

  • This invention relates to a modular printer.
  • the invention relates particularly, but not necessarily exclusively, to a modular commercial printer for effecting high speed, digital, photographic quality, commercial printing.
  • the invention relates specifically to a loading mechanism for loading print media into a modular commercial printer.
  • the document DE 184 440 C discloses a mechanism for feeding sheets in a printing press, having the features of the preamble of Claim 1.
  • the applicant has also proposed a commercial printer using a number of floor mounted printers having pagewidth print heads.
  • This commercial printer is intended for extremely high production rates such as up to five 180 page documents per second.
  • the applicant has recognised a need for a commercial printer which occupies a smaller volume and which has a lower throughput rate but of the same quality as the applicant's previously proposed Memjet commercial printer.
  • a print media loading mechanism for a printer, the loading mechanism being configured to feed print media in a feed direction and including:
  • Each belt may pass over a pair of spaced rollers, the rollers of one of the belts being in alignment with the rollers of the other of the belts so that rotational axes of said aligned rollers extend parallel to each other and are spaced from each other in said direction transverse to the feed direction. More particularly, a roller of each belt may be arranged at an upstream region of the belt with a second roller being arranged at a downstream region of the belt.
  • upstream region is meant that region of the belt closer to an inlet end of the printer and a “downstream region” of the belt means that region of the belt adjacent an exit region of the printer.
  • first rollers of each belt may be arranged in vertically aligned relationship with the second rollers of each belt also being arranged in vertically aligned relationship.
  • the displacement means may act on the aligned rollers of the belt for urging said aligned rollers towards each other when print media is to be loaded and for moving said aligned rollers away from each other when loading has been completed.
  • the displacement means may include an elongate drive member and a pair of driven members wherein each driven member is arranged proximate a respective end of the drive member, the drive member being operable to displace the driven members to effect displacement of said aligned rollers in said direction transverse to the feed direction, the driven members being connected by a connector to their associated, aligned rollers.
  • an elongate drive member with its associated driven member is arranged on each side of the belt.
  • the drive member may be a worm screw
  • each driven member may be a traverser block mounted to be displaceable along the worm screw on rotation of the worm screw
  • each connector may be a scissors connector connecting each traverser block to its associated, aligned rollers.
  • reference numeral 10 generally designates a printer, in accordance with the invention.
  • the printer 10 is a modular printer to be used in combination with other, identical printers, as will be described in greater detail below for effecting high speed, digital, photographic quality, commercial printing.
  • Arrays of the printers 10 can be combined to provide scalable printing systems. However, single printers 10 may also be used individually, if desired.
  • the printer 10 comprises a housing 12.
  • the housing 12 is made up of an upper cover 14, a lower cover 16 ( Figure 9 ), a first side wall 18 and a second, opposed side wall 20 ( Figure 9 ).
  • Each side wall 18, 20 terminates in an end cap or cheek molding 22.
  • Each cheek molding 22 is the same to reduce the costs of production of the printer 10.
  • Each cheek molding 22 has a slot in which an application-specific insert 24 is received.
  • the housing 12 surrounds a frame 26. Internal components of the printer 10 are supported on the frame 26.
  • each cheek molding 22 at each end of the housing 12 support a guide roller 28 adjustably between them.
  • each cheek molding 22 defines an arcuate slot 30 within which an axle of its associated roller 28 is received.
  • the printers 10 are stacked together to form a stack 40.
  • the stack 40 is arranged on a support table 42.
  • a lowermost printer 10 in the stack 40 is locked to the table 42 by means of locking feet 44 of the printer 10.
  • the locking feet 44 of each subsequent printer 10 in the stack 40 are received in associated holes 46 in a top of a subjacent printer 10.
  • Each locking foot 44 has a bayonet fitting so that, when the foot 44 is inserted into one of the holes 46 of the subjacent printer or the table 42, as the case maybe, a quarter turn of the foot 44 locks the upper printer 10 with respect to the subjacent printer 10 or the table 42.
  • the printers 10 when stacked horizontally, may be offset with respect to each other by locking the locking feet 44 of one printer 10 into the appropriate holes 46 of the subjacent printer.
  • a plurality of serially aligned holes 46 is arranged adjacent each cheek molding 22.
  • the offset stacking of the printers 10 allows print media, such as paper 48, to be fed from unwinders (not shown) into each of the printers 10 at a predetermined angle and to be fed out of the printers 10 at a suitable exit angle. If the paper 48 is to be fed in and out of the printers 10 horizontally, the printers 10 of the stack 40 are vertically aligned with respect to each other.
  • FIG 6 another embodiment of the stack 40 is shown.
  • the printers 10 are arranged vertically and are spaced horizontally with respect to each other.
  • paper 48 is fed into each printer 10 at an upper end of the printer and is fed out, after printing, through a bottom of each printer 10.
  • the stack 40 is supported on a framework 49 with the printer at one end of the stack 40 being locked to an end plate 51 of the framework 49 via its locking feet 44.
  • Adjacent printers 10 in the stack 40 are locked together by inserting the locking feet 44 of one printer 10 into the appropriate holes 46 of the adjacent printer 10.
  • a control console 54 is provided for controlling operation of the printer stack 40.
  • Each printer 10 communicates with its controller and with other printers in the stack 40 via a USB2 connection 50 received in a double USB port arrangement 52.
  • the port arrangement 52 has an inlet port and an outlet port for enabling the printers 10 of the stack 40 to be daisy-chained together and to communicate with each other.
  • Each printer includes a print engine 56 made up of a pair of opposed print head assemblies 54 for enabling double-sided printing to be effected.
  • the print head assembly 54 ( Figure 11 ) of the print engine 56 of the printer 10 can print in up to twelve colors.
  • each print head assembly 54 is a duplexed print head so that, if desired, six colors, duplicated, can be printed by each print head assembly 54.
  • Ink is fed to the print engine 56 via an ink coupling box 58.
  • the coupling box 58 supports twelve ink couplings 60 thereon.
  • Ink hoses 64 are coupled to the coupling box 58 via the couplings 60 and communicate with the print head assemblies 54 of the print engine 56 via an ink connector 62 ( Figure 9 ).
  • a power connection port 66 is also supported on the ink coupling.
  • the port 66 is received through an opening 68 in one of the inserts 24 of one of the cheek moldings 22.
  • the same insert 24 supports an air coupling 70.
  • An air hose 72 ( Figure 7 ) feeds air to the print head assemblies 54 of the print engine 56 to maintain print head nozzles (not shown) of the print head assemblies 54 free of debris and foreign matter.
  • a roller assembly 74 is mounted at an inlet end of the printer 10.
  • the roller assembly 74 includes a drive roller 76 and a driven roller 78.
  • the drive roller 76 is driven by a drive motor 80 supported on a metal bracket 82.
  • the metal bracket 82 is mirrored by a corresponding bracket 84 at an opposed end of the roller assembly 74.
  • the brackets 82 and 84 are supported on the frame 26.
  • roller assembly 86 is provided at an outlet end of the printer 10.
  • the roller assembly 86 has a drive roller 88 driven by a drive motor 90 and a driven roller 92.
  • the rollers 86 and 92 are supported between metal brackets 94 and 96.
  • the brackets 94 and 96 are secured to the frame 26.
  • the bracket 94 also supports the motor 90.
  • the drive roller 76 drives the driven roller 78 via a set of helical gears 132.
  • a similar arrangement applies in respect of the roller 88 and 92 of the roller assembly 86.
  • the print engine 56 is supported by a chassis comprising a pair of opposed metal brackets 100, 102 mounted downstream (in a direction of feed of the paper) of the roller assembly 74.
  • Each metal bracket 100, 102 supports one of the print head assemblies 54 of the print engine 56.
  • the print engine 56 is shown in greater detail in Figures 10 to 12 of the drawings. As described above, the print engine 56 comprises two print head assemblies 54. The print head assemblies 54 are arranged in opposed relationship to enable double sided printing to be effected. In other words, the paper 48 passes between the print head assemblies 54.
  • the brackets 100, 102 support the print head assemblies 54 and position the print head assemblies 54 approximately 0.75mm apart from the web of paper 48. This distance is automatically adjusted by the brackets 100, 102 to maintain constant spacing with varying paper thickness.
  • print heads of the print head assemblies 54 are so designed as to allow for close proximity to the rollers 76 and 78 resulting in a closely controlled paper to print head gap.
  • Each print head assembly 54 comprises a first print head 104 and a second, adjacent print head 106.
  • Each print head 104, 106 is made up of two modules 104.1 and 104.2 and 106.1 and 106.2, respectively.
  • the modules 104.1 and 106.1 are coupled together and are controlled by a first printed circuit board (PCB) 108.
  • the modules 104.2 and 106.2 are coupled together and are controlled by a second printed circuit board (PCB) 110.
  • PCB's 108 and 110 communicate with print head chips 112 of the print heads 104 and 106 via flex PCB's 114.
  • These flex PCB's 114 terminate in terminal pads 116 on moldings 118 of the modules 104.1, 104.2, 106.1 and 106.2 of the print heads 104 and 106.
  • the terminal pads 116 communicate with corresponding pads (not shown) of the PCB's 108, 110.
  • the moldings 118 are mirror images of each other, each having ink inlets 120 at a free end thereof. Ink is fed in at one end of interconnected moldings 118 only so that the inlets 120 not being used are plugged by appropriate plugs.
  • the PCB's 108, 110 are mirror images of each other. This reduces the cost of production of the printer 10 and also enables rapid and easy assembly of the printer 10.
  • the PCB's 108 and 110 communicate with each other via a serial cable 122.
  • One of the PCB's 108, 110 is connected via a connector 124 to the USB circuit board 98.
  • Each PCB 108, 110 includes two print engine controllers (PEC's) 126 and associated memory devices 128.
  • the memory devices 128 are dynamic random access memory (DRAM) devices.
  • each print head assembly 54 is supported on the frame 100, 102 via an end plate 130 ( Figure 13 ).
  • the print engine 56 is shown in greater detail in Figure 11 of the drawings.
  • the print engine 56 comprises the two print head assemblies 54.
  • each print head assembly 54 comprises two print heads 104, 106.
  • Each print head 104, 106 has a print head chip 112 associated therewith.
  • the print head chips 112 of the print heads 104, 106 are supported along a longitudinal edge portion of the moldings 118.
  • the edge portion of each molding 118 which carries the print head chip 112 is arcuate.
  • the arcuate portion of each molding 118 has a radius of curvature which approximates that of the radius of the rollers 76, 78.
  • This design of the print heads 104, 106 allows for close proximity of the print head chips 112 to the rollers 76, 78 resulting in a closely controlled paper to print head gap. In so doing the printhead chip 112 prints in a portion of the paper, which is taut, resulting in a more accurate deposition of ink drops on the paper 48.
  • an air channel 138 is arranged adjacent each print head chip 112 for feeding air to the print head chip 112 from the air hose 72.
  • each print head assembly 54 can print the twelve "colors" having the appropriate "colors” charged into the galleries 136 of the print heads 104, 106. Where six "colors" are to be printed, these are normally cyan, magenta, yellow and black. The remaining galleries 136 then have an ink fixative and a varnish. Where twelve "colors” are to be printed, the "colors” are cyan, magenta, yellow, black, red, green, blue, either three spot colors or two spot colors and infrared ink, and the fixative and the varnish.
  • the printer 10 is designed so that, where six "colors" are to be printed, the printer can print at a printing speed of up to 1,360 pages per minute at a paper speed of 1.6 m/s. Where twelve "colors" are to be printed, the printer 10 is designed to operate at a printing speed of up to 680 pages per minute at a paper speed of 0.8 m/s.
  • the high speed is achieved by operating the nozzles of the print head chips 112 at a speed of 50,000 drops per second.
  • Each print head module 104.1, 104.2, 106.1, 106.2 has six nozzle rows per print head chip 112 and each print head chip 112 comprises 92,160 nozzles to provide 737,280 nozzles per printer. It will be appreciated that, with this number of nozzles, full 1600dpi resolution can be achieved on a web width of 18.625 inches. The provision of a web width of this dimension allows a number of pages of a document to be printed side-by-side.
  • the amount of memory 128 installed on each board 108, 110 is application dependent. If the printers 10 are being used for unchanging pages, for example, for offset press replacement, then 16 megabytes per memory module is sufficient. If the amount of variability on each page is limited to text, or a small range of variable images, then 16 megabytes is also adequate. However, for applications where successive pages are entirely different, up to 1 gigabyte may need to be installed on each board 108, 110 to give a total of 4 gigabytes for the print engine 56. This allows around 2,000 completely different pages to be stored digitally in the print engine 56. The local buffering of the data also facilitates high speed printing by the printers 10.
  • the spacing between the print engine 56 and the exit roller assembly 86 is approximately one metre to allow for a one second warm-set ink drying time at a web speed of the paper 48 of approximately 0.8 metres per second.
  • the fixative is used in one of the ink galleries 136.
  • warm air is blown into the interior of the printer 10 from a source (not shown) connected to an air inlet 140 ( Figure 1 ) via an air hose 142.
  • the air inlet communicates with a metal air duct 144 ( Figure 9 ) which blows the warm air over the paper 48 exiting the print engine 56.
  • Warm air is exhausted from the interior of the printer by means of vents 146 in the side wall 20 of the housing 12 of the printer 10.
  • the printer 10 includes a print media loading mechanism 150 for loading the paper 48 into the interior of the printer 10.
  • the loading mechanism 150 comprises a pair of opposed endless belts 152 (shown more clearly in Figures 15 to 18 of the drawings). Although not illustrated as such, these belts 152 are foraminous to enable the warm air ducted in through the duct 144 to be blown through the belts 152 over both surfaces of the paper 48, after printing, in use.
  • Each belt 152 passes around a pair of spaced rollers 154.
  • the rollers 154 are held captive to be vertically slidable in slides 156.
  • the slides 156 are mounted on the frame 26 of the printer 10.
  • Each roller 154 is mounted at one end of an arm 158.
  • the opposed end of each arm 158 is connected at a common pivot point 160 to a traverser block 162 so that the arms 158 are connected to their associated traverser block 162 scissors-fashion.
  • the traverser block 162 is, in turn, mounted on a lead or worm screw 164.
  • the worm screw 164 is rotatably driven by a motor 166 supported on a bracket 168.
  • the rollers 154 are driven by a motor 170 ( Figure 18 ).
  • the mechanism 150 When it is desired to load paper 48 into the printer 10, the mechanism 150 is operated by a paper load button 172 ( Figures 1 and 8 ). This causes the roller motor 170 to be activated as well as the motor 166. Rotation of the motor 166 causes the traverser blocks 162 to move in the direction of arrows 174 to bring the belts 152 into abutment with each other. A leading edge of the paper 48 is fed between the belts 152, is grabbed by the belts 152 and is fed through the printer 10 to exit through the exit roller assembly 86. Once the paper 48 has been loaded, the direction of the motor 166 is reversed so that the traverser blocks move in directions opposite to that of arrows 174 causing the belts 152 to move to the position shown in Figure 16 of the drawings. Thus, during printing, the belts 152 are spaced from, and do not bear against, surfaces of the paper 48.
  • a modular printer which can print at commercial printing speeds is provided for the printing of documents.
  • Several modules can be arrayed in combination with inserting machines for published documents, such as magazines, with variable paper weights.
  • print module redundancy allows paper splicing on a stopped web with no down time as the other printer modules in the stack 40 take up printing of the pages which would normally be printed by the out of operation printer 10.
  • Each printer 10 is provided with its document printing requirements over the USB2 communications network (or optional Ethernet) from a work station such as the console 54.
