Definitions
- This invention relates to a printer of the type used to print images onto textiles, such as a printer for printing labels for attachment to garments, and to an ink cartridge for such a printer.
- a printer of the type used to print images onto textiles
- ink cartridge for such a printer.
- textile printer will be used herein to refer to a printer for printing images onto textiles.
- Textile printers may be used to print images onto a range of textiles of various sizes, and in particular may be used to print images onto labels for garment.
- Such labels will generally provide information regarding the make of a garment, the type of textile from which the garment has been made, and washing instructions for the garment. It is therefore important that printed labels of this type are able to endure high temperatures during washing, for example, and that images printed onto the labels remain visible and legible generally for the life of the garment to which they are attached.
- Liquid inks are generally not suitable for use in textile printers, as the liquid ink would tend to run and fade on the textile onto which it had been applied.
- Fabrics that may be employed in textile printing include polymers, such as various polyesters and polyamides. More specifically, such fabrics include polyester, polyester satin, nylon, cotton, self-adhesive satins, lace, twill, GroGrain and imitation leather materials.
- a known textile printer comprises a central drum rotatable about an axis.
- a textile to be printed is fed onto the drum in such a manner that it extends around at least a portion of the circumference of the drum.
- the central drum rotates the textile is fed over the drum enabling a continuous strip of textile to be printed.
- a print cylinder rotatable about an axis is positioned so that, in use, a circumferentially outer surface of the print cylinder just touches a circumferentially outer surface of the central drum.
- the axis of the print cylinder is spaced apart from, and substantially parallel to the axis of the central drum.
- the circumferentially outer surface of the print cylinder is shaped to apply a particular impression onto a textile extending around the central drum.
- the surface of the print cylinder may be directly contoured to provide the required impression, or a relief image plate made from any suitable material, such a photopolymer material, may be applied to the print cylinder.
- ink In order to translate an impression onto a textile extending around the central cylinder, ink must be applied to the print cylinder. It is known to apply ink to a print cylinder by means of an anilox roller.
- An anilox roller has a surface comprising a plurality of small cavities adapted to hold the ink. Ink is initially applied to the anilox roller through use of an ink duct and the surface of the anilox roller absorbs ink from the duct.
- the anilox roller is positioned so that, in use, its axis is substantially parallel to the axis of the print cylinder, it is spaced apart from the central drum, and its circumferential outer surface just touches the circumferential outer surface of the print cylinder. In use, the anilox roller is rotated as the print cylinder rotates, thus coating the print cylinder with ink.
- the print cylinder rotates as the central drum rotates. Since the print cylinder is positioned so that its outer surface just touches the outer surface of the central drum, rotation of the print cylinder and the central drum will result in an impression being translated onto the textile passing over the outer surface of the central drum. The circumference of the print cylinder will determine the repeat length of the impression translated onto the textile.
- Such an adjustment may be time consuming, since it is not only necessary to adjust the position of the print cylinder in a direction that is perpendicular to the axis of the print cylinder, but it is also necessary to adjust the print cylinder in a direction parallel to the print cylinder axis, to ensure appropriate lateral positioning of the print cylinder relative to the central drum.
- the adjustment process must also take into account the variable size of different print cylinders.
- the print cylinder will be supplied with ink of a particular colour by the anilox roller, which is itself supplied by ink from the ink duct. If, therefore, the textile is to be printed with more than one colour, more than one print cylinder must be used.
- the textile printer will comprise three print cylinders spaced apart circumferentially around the central drum. Each print cylinder will have associated with it, an anilox roller and ink duct.
- the image When a textile is printed with an image having more than one colour, the image will be printed in stages. At each stage a portion of the image in a particular colour will be translated onto the fabric by a particular print cylinder. The complete image will be produced once each printing cylinder has contacted the portion of the textile being printed. Thus, if an image containing three colours is to be printed onto a textile, the complete image will be produced once the portion of the textile being printed has received an impression from all three printing cylinders.
- each print cylinder In order to ensure that the different colours are applied to the appropriate parts of the textile relative to the other colours, it is necessary to ensure that the individual print cylinders are in register with one another. In order to ensure that each print cylinder is in register with other print cylinders, each cylinder may have to be rotated a predetermined distance relative to the central drum. This process is time consuming and requires a high level of skill. In particular, it is necessary to move each print cylinder in turn out of contact with the central drum, rotate the print cylinder a small amount, reposition the print cylinder, and check whether the print cylinder is now in register. If the print cylinder is still not in register, the process must be repeated until it is.
- a further problem with known textile printers is that each time a print cylinder is removed from the textile printer, for example, for cleaning, it is necessary to accurately reposition the print cylinder when the cylinder is replaced in the textile printer for further use.
- GB 0 9365 relates to a printing machine and particularly to a printing machine operating with fatty inks or colours and by means of impression rollers, upon paper, textile fabrics, floor coverings, metal sheets and the like.
- the printing machine comprises a frame or frames on which all the parts of the machine which, upon a change of colour or ink or design are required to be removed or cleaned, are supported.
- the frame or frames are detachable from the main framework of the printing machine so that when a change of colour or design is necessary, the frame containing the relevant parts may be detached from the machine and immediately replaced by another frame with components attached thereto which are ready to be used.
- European patent application No. 0096646 relates to a process and a device for pre-positioning several inking stations forming part of a printing machine.
- the invention relates particularly to the pre-positioning of printing cylinders such as the plate cylinder and screen cylinder / fountain cylinder assemblies of a printing machine, in particular a flexographic printing machine.
- a textile printer comprising:
- the print cylinder retainer comprises a first retaining portion forming part of the first retaining arm, and a second retaining portion forming part of the second arm.
- the print cylinder adjuster further comprises a clamp for clamping the print cylinder in position within the print cylinder retainer.
- the clamp comprises a first clamp portion moveable within the first retaining portion, and a second clamp portion moveable within the second retaining portion.
- the print cylinder retainer further comprises a first and second clamp portion activator for causing movement of each clamp portion within a respective retaining portion.
- each clamp portion activators comprises a pneumatic cylinder forming part of a respective retaining arms.
- the print cylinder adjuster further comprises a first adjustment arm, and a second adjustment arm, the first adjustment arm being attachable to the first retaining arm, and the second adjustment arm being attachable to the second retaining arm, the first and second adjustment arms allowing further adjustment of the print cylinder when the print cylinder is held in position in the print cylinder retainer by the clamp.
- a print cylinder is held in position relative to the central drum. Accurate positioning of the print cylinder is possible since the retaining arms restrict any lateral movement of the print cylinder.
- the first and second retaining arms are configured so that the position of the print cylinder may be adjusted by movement of the print cylinder either towards or away from the central drum by movement of the print cylinder along each of the retaining arms and within the print cylinder retaining portions.
- the first side of the print cylinder is substantially coplanar with the first side of the central drum
- the second side of the print cylinder is substantially coplanar with the second side of the central drum
- the central drum rotates about a shaft, and an end of the first retaining arm is, in use, in contact with a first end of the shaft, and an end of the second retaining arm is, in use, in contact with a second end of the shaft.
- each of the first and second retaining arms extend substantially radially from the axis of the central drum. This positioning of the first and second arm facilitates positioning of the print cylinder and ensures that the print cylinder is appropriately aligned with the central drum.
- the printer further comprises a cartridge comprising a chambered ink duct, an ink roller attached to the ink duct, and an attachment for removably attaching the cartridge to the textile printer.
- the ink duct and ink roller are formed into a single cartridge which cartridge is removably attachable to a printer. This means that the process of removing an ink roller for cleaning or repair is greatly simplified.
- the ink roller and ink duct are contained within a single cartridge, it is not necessary to accurately position the ink roller relative to the ink duct, since the dimensions of the cartridge will ensure that the ink roller is appropriately positioned relative to the ink duct.
- the ink roller comprises an anilox roller.
- the cartridge comprises an attachment extending from a side of the cartridge.
- the attachment is receivable within the printer to which the cartridge is to be installed thus allowing easy attachment and removal of the cartridge from the printer.
- the chambered ink duct comprises a hopper having at least one open face.
- the open face of the hopper allows ink to be poured into the hopper either manually or through an automated process.
- the cartridge further comprises a tray for collecting unused ink.
- the tray may be emptied when the cartridge is removed from the printer.
- the cartridge is attachable to the print cylinder retainer. This ensures that the cartridge is appropriately aligned with the print cylinder.
- the first and second attachment portions are receivable in the first and second retaining portions respectively of the print cylinder retainer.
- the print cylinder comprises a gear mechanism contained within a gear housing, which gear housing is rotatably movably attached to the printer, the printer further comprising a gear housing adjuster engageable with the gear housing for causing rotational movement of the gear housing, thereby causing corresponding rotational movement of the print cylinder.
- gear mechanism By means of the gear mechanism, it is possible to rotate the print cylinder relative to the central drum. In a printer comprising more than one print cylinder, such movement of one of the print cylinders will cause relative movement of that print cylinder relative to the second print cylinder. Such movement may be used to bring the two print cylinders into register with one another.
- the gear housing comprises a worm wheel
- the gear housing adjuster comprises a worm threadably engageable with the worm wheel of the gear housing.
- the worm may be operated by any desirable mechanisms such as a control knob. Operation of the control knob will cause rotation of the worm which in turn will cause rotation of the gear housing.
- the print cylinder comprises an output shaft, and an input gear attached to the output shaft, which input gear is engageable with a plurality of planet gears which in turn are engageable with a ring gear enclosed within the gear housing.
- an embodiment of a printer according to the present invention is designated generally by the reference numeral 2.
- the printer 2 is particularly suitable for printing images in the form of text or other graphics onto a continuous strip of textile material.
- the continuous strip of material to be printed is fed onto the central drum, and once printed, will be cut to form individual labels for attachment to garments.
- the labels will typically indicate washing instructions and material composition of the garment to which they are attached.
- the printer comprises a front plate 3 and a back plate 5.
- the printer comprises a central drum 4 rotatable about a central shaft 6, and two print cylinders 8. Associated with each print cylinder 8 is an anilox roller 10. Each of the print cylinders will transfer an image in a particular colour onto the strip of material.
- printer 2 comprises two print cylinders 8 in order to print two colours onto the material. However, if more colours are to be printed onto the strip of material, the printer 2 would have more print cylinders. Similarly, if the material is to be printed with one colour only, the printer would have a single print cylinder.
- the printer cylinder 8 is supported between the front plate 3 and back plate 5 by means of the central shaft 6 which is attached to each plate 3, 5.
- the anilox roller 10 associated with each print cylinder forms part of an ink cartridge 12 shown in more detail in Figures 3a , 3b , 3c and 4 .
- the cartridge 12, in addition to the anilox roller 8, comprises a chambered ink duct 14, comprising a hopper tray 15 into which ink may be poured either manually, or by an automated process.
- the print cylinder 8 In order to print an image having a particular colour onto material passing around the circumference of the central drum 4, the print cylinder 8 is rotated as the central drum rotates, causing the material to be printed to pass between the central drum 4 and the print cylinder 8.
- the anilox roller 10 is also rotated, causing ink contained in the hopper tray 15 to be transferred onto the surface of the anilox roller.
- the surface of the anilox roller is formed with small engraved cells which enable the anilox roller to retain a predetermined amount of ink in the indentations.
- the size of the cells may vary from roller to roller, but typically will have a diameter of between 5 and 50 microns.
- the print cylinder 8 and anilox roller 10 are positioned so that, in use, the anilox roller 10 is in contact with the print cylinder 8, and the print cylinder 8 is also in contact with the central drum 4 or, in use, with a material to be printed.
- each of the central drum 4, print cylinder 8 and anilox roller 10 comprises a drive gear 60, 62, 64 respectively. In use the central drum drive gear 60 and the print cylinder drive gear 62 will engage with one another. The print cylinder drive gear 62 will also engage with the anilox roller drive gear 64. This ensures that rotation of the central drum 4, print cylinder 8 and anilox roller 10 is synchronised.
- print cylinder 8 and anilox roller 10 rotate, ink from the hopper tray 15 transfers to the anilox roller 10, and then to the print cylinder 8.
- the surface of the print cylinder 8 is contoured so that when the material passes between the central drum and the print cylinder 8, an impression is transferred onto the material.
- the positions of the print cylinder 8 and the anilox roller can be adjusted relative to one another and to the central drum 4 as will be described in more detail below, in order that a predetermined level of pressure is applied by the central drum 4 and the print cylinder 8 onto material passing over the central drum 4, and between the anilox roller 10 and the print cylinder 8.
- the ink cartridge 12 further comprises an attachment for allowing removable attachment of the cartridge 12 to the textile printer 2.
- the attachment comprises a first attachment portion 18 extending from a first side 20 of the cartridge 12, and a second attachment portion 22 extending from a second side 24 of the cartridge 12.
- Each of the attachment portions 18, 22 comprises two attachment rollers 26 which are receivable within a roller receiving portion of printer 2 as will be described in more detail hereinbelow.
- the cartridge 12 also comprises an anilox roller adjustment in the form of screws 28 for adjusting the position of the ink roller relative to the chambered duct.
- the cartridge 12 further comprises a tray 30 for collecting any ink not adhering to the surface of the anilox roller 10.
- the printer 2 further comprises a print cylinder adjuster 32 in the form of a pair of spaced apart retaining arms 34, 36 and adjustment arms 65, 66.
- the print cylinder adjuster 32 further comprises receiving portions 38 for receiving the print cylinder 8, and also for receiving the attachment rollers of the ink cartridge 12.
- the arms 34, 36 are each shaped to receive the print cylinder 8.
- the axes of each of the central drum 4, print cylinder 8, and anilox roller 10 will all be substantially parallel to one another.
- the adjustment arms 65, 66 are pivotably attached to the front plate 3 and the back plate 5 respectively, at pivot points 67, 68.
- the print cylinder adjuster 32 further comprises clamp 69 operated by a pneumatic cylinder 40 forming part of a respective arm 34,36. In use, when print cylinder 8 is to be positioned relative to the central drum 4, the print cylinder will be positioned between adjustment arm 34, 35 in receiving portions 38. Print cartridge 12 will also be positioned between the arms 34, 36 in the receiving portion 38.
- the clamp 69 will be caused to move towards the print cartridge 12 engaging with the attachment rollers 26, causing the ink cartridge 12 to bear down on bearings 70 of the print cylinder 8.
- the position of the print cylinder may be adjusted by means of impression adjuster screws 42.
- the screws 42 are connected to rods 71 which are each operably connected to a respective arm 65,66 causing the arms to pivot about pivot points 67, 68.
- Each adjustment arm 65, 66 is moveably attached to a respective arm 34, 35, by means of a pin 72 retained in a slot 73. Movement of the arms 65, 66 causes movement of the receiving portion 38.
- Each of the arms 34, 36 has a first end 42 and a second end 44.
- the second ends 44 of each of the arms 34, 36 abut with the central shaft 6 of the central drum 4. This means that each of the arms 34, 36 extends substantially radially from the shaft 6.
- the length of the print cylinder 8 is approximately the same as the length of the central drum 4 and the portions 40 are positioned so that when a cylinder 8 is held in position between the portions 40, sides 46 of the print cylinder 8 are coplanar with sides 48 of the central drum 4.
- print cylinders of different diameters may easily be positioned correctly relative to the central drum 4 since once a print cylinder 8 is positioned within the arms 34, 36 the sides of the print cylinder 46 will be positioned appropriately relative to the sides 48 of the central drum.
- a print cylinder 8 is retained between arms 34, 36, only movement that is possible is in a direction substantially perpendicular to the axis of the central shaft is possible.
- movement is effected by adjusting the adjustment arms 65, 66 via the impression adjuster screw 42. This in turn results in movement of the print cylinder and print cartridge 12 in a direction either towards or away from the central drum 6 in a direction that is substantially perpendicular to the axis of the central shaft 6.
- the printer 2 comprises two print cylinders 8 each with an associated anilox roller 10.
- the printer 2 is therefore set up to print two different colours on to a continuous strip of material extending round the central drum 4.
- Each print cylinder comprises a print registration adjusting gearbox 50 that extends through a back plate 5 of the printer 2.
- the print registration adjusting gear box 50 comprises an outer casing 54 enclosing an input gear 56 attached to an output shaft 57 of the print cylinder 8, and planet gears 58 orbiting the input gear.
- the gear box comprises a ring gear 59, and the planet gears 58 are in engagement with the ring gear.
- An outer surface of the casing 54 is gearcut to form a worm wheel.
- the gear box 50 further comprises a worm 60 threadably engageable with the threaded outer surface of the gear casing 50.
- the outer casing 50 associated with the particular printer cylinder 8 is rotated by turning knob 62 which causes the worm 60 to rotate. Due to the threaded engagement of the worm 60 and the casing 50, rotation of the worm causes corresponding rotation of the outer casing.
- the planet gears 58 When the outer casing is rotated, the planet gears 58 will move with the outer casing and will cause rotation of the output shaft of the print cylinder 8 through their engagement with the input gear 56 and the ring gear 59. The adjustment may thus be carried out without having to move the print cylinder away from the central drum.
Description
- This invention relates to a printer of the type used to print images onto textiles, such as a printer for printing labels for attachment to garments, and to an ink cartridge for such a printer. The term "textile printer" will be used herein to refer to a printer for printing images onto textiles.
- Textile printers may be used to print images onto a range of textiles of various sizes, and in particular may be used to print images onto labels for garment. Such labels will generally provide information regarding the make of a garment, the type of textile from which the garment has been made, and washing instructions for the garment. It is therefore important that printed labels of this type are able to endure high temperatures during washing, for example, and that images printed onto the labels remain visible and legible generally for the life of the garment to which they are attached.
- In order produce labels meeting these requirements, it is known to use high viscosity inks to print images onto textiles. Liquid inks are generally not suitable for use in textile printers, as the liquid ink would tend to run and fade on the textile onto which it had been applied.
- Fabrics that may be employed in textile printing include polymers, such as various polyesters and polyamides. More specifically, such fabrics include polyester, polyester satin, nylon, cotton, self-adhesive satins, lace, twill, GroGrain and imitation leather materials.
- A known textile printer comprises a central drum rotatable about an axis. A textile to be printed is fed onto the drum in such a manner that it extends around at least a portion of the circumference of the drum. As the central drum rotates the textile is fed over the drum enabling a continuous strip of textile to be printed.
- A print cylinder rotatable about an axis, is positioned so that, in use, a circumferentially outer surface of the print cylinder just touches a circumferentially outer surface of the central drum. In use, the axis of the print cylinder is spaced apart from, and substantially parallel to the axis of the central drum. The circumferentially outer surface of the print cylinder is shaped to apply a particular impression onto a textile extending around the central drum. In this respect, the surface of the print cylinder may be directly contoured to provide the required impression, or a relief image plate made from any suitable material, such a photopolymer material, may be applied to the print cylinder.
- In order to translate an impression onto a textile extending around the central cylinder, ink must be applied to the print cylinder. It is known to apply ink to a print cylinder by means of an anilox roller. An anilox roller has a surface comprising a plurality of small cavities adapted to hold the ink. Ink is initially applied to the anilox roller through use of an ink duct and the surface of the anilox roller absorbs ink from the duct. The anilox roller is positioned so that, in use, its axis is substantially parallel to the axis of the print cylinder, it is spaced apart from the central drum, and its circumferential outer surface just touches the circumferential outer surface of the print cylinder. In use, the anilox roller is rotated as the print cylinder rotates, thus coating the print cylinder with ink.
- In use, the print cylinder rotates as the central drum rotates. Since the print cylinder is positioned so that its outer surface just touches the outer surface of the central drum, rotation of the print cylinder and the central drum will result in an impression being translated onto the textile passing over the outer surface of the central drum. The circumference of the print cylinder will determine the repeat length of the impression translated onto the textile.
- In order to ensure an appropriate quality of print, it is necessary to ensure that the relative position of the print cylinder and the central drum is such that a predetermined pressure is applied to the textile during the printing process. This is achieved by adjusting the printing cylinder relative to the central drum.
- Such an adjustment may be time consuming, since it is not only necessary to adjust the position of the print cylinder in a direction that is perpendicular to the axis of the print cylinder, but it is also necessary to adjust the print cylinder in a direction parallel to the print cylinder axis, to ensure appropriate lateral positioning of the print cylinder relative to the central drum. In addition, the adjustment process must also take into account the variable size of different print cylinders.
- In use, the print cylinder will be supplied with ink of a particular colour by the anilox roller, which is itself supplied by ink from the ink duct. If, therefore, the textile is to be printed with more than one colour, more than one print cylinder must be used. Thus if a textile is to be printed with three colours, the textile printer will comprise three print cylinders spaced apart circumferentially around the central drum. Each print cylinder will have associated with it, an anilox roller and ink duct.
- When a textile is printed with an image having more than one colour, the image will be printed in stages. At each stage a portion of the image in a particular colour will be translated onto the fabric by a particular print cylinder. The complete image will be produced once each printing cylinder has contacted the portion of the textile being printed. Thus, if an image containing three colours is to be printed onto a textile, the complete image will be produced once the portion of the textile being printed has received an impression from all three printing cylinders.
- In order to ensure that the different colours are applied to the appropriate parts of the textile relative to the other colours, it is necessary to ensure that the individual print cylinders are in register with one another. In order to ensure that each print cylinder is in register with other print cylinders, each cylinder may have to be rotated a predetermined distance relative to the central drum. This process is time consuming and requires a high level of skill. In particular, it is necessary to move each print cylinder in turn out of contact with the central drum, rotate the print cylinder a small amount, reposition the print cylinder, and check whether the print cylinder is now in register. If the print cylinder is still not in register, the process must be repeated until it is.
- A further problem with known textile printers is that each time a print cylinder is removed from the textile printer, for example, for cleaning, it is necessary to accurately reposition the print cylinder when the cylinder is replaced in the textile printer for further use.

GB 0 9365 - The printing machine comprises a frame or frames on which all the parts of the machine which, upon a change of colour or ink or design are required to be removed or cleaned, are supported. The frame or frames are detachable from the main framework of the printing machine so that when a change of colour or design is necessary, the frame containing the relevant parts may be detached from the machine and immediately replaced by another frame with components attached thereto which are ready to be used.

- Advantageously, the first side of the print cylinder is substantially coplanar with the first side of the central drum, and the second side of the print cylinder is substantially coplanar with the second side of the central drum.
- Preferably, the central drum rotates about a shaft, and an end of the first retaining arm is, in use, in contact with a first end of the shaft, and an end of the second retaining arm is, in use, in contact with a second end of the shaft.
- This means that each of the first and second retaining arms extend substantially radially from the axis of the central drum. This positioning of the first and second arm facilitates positioning of the print cylinder and ensures that the print cylinder is appropriately aligned with the central drum.
- Preferably, the printer further comprises a cartridge comprising a chambered ink duct, an ink roller attached to the ink duct, and an attachment for removably attaching the cartridge to the textile printer.
- By means of the present invention the ink duct and ink roller are formed into a single cartridge which cartridge is removably attachable to a printer. This means that the process of removing an ink roller for cleaning or repair is greatly simplified. In addition, because the ink roller and ink duct are contained within a single cartridge, it is not necessary to accurately position the ink roller relative to the ink duct, since the dimensions of the cartridge will ensure that the ink roller is appropriately positioned relative to the ink duct.
- Preferably, the ink roller comprises an anilox roller.
- Advantageously, the cartridge comprises an attachment extending from a side of the cartridge. The attachment is receivable within the printer to which the cartridge is to be installed thus allowing easy attachment and removal of the cartridge from the printer.
- Preferably, the chambered ink duct comprises a hopper having at least one open face. The open face of the hopper allows ink to be poured into the hopper either manually or through an automated process.
- Conveniently, the cartridge further comprises a tray for collecting unused ink. The tray may be emptied when the cartridge is removed from the printer.
- Advantageously, the cartridge is attachable to the print cylinder retainer. This ensures that the cartridge is appropriately aligned with the print cylinder.
- In an embodiment of the cartridge having first and second attachment portions for attaching the cartridge to the printer, the first and second attachment portions are receivable in the first and second retaining portions respectively of the print cylinder retainer.
- Preferably, the print cylinder comprises a gear mechanism contained within a gear housing, which gear housing is rotatably movably attached to the printer, the printer further comprising a gear housing adjuster engageable with the gear housing for causing rotational movement of the gear housing, thereby causing corresponding rotational movement of the print cylinder.
- By means of the gear mechanism, it is possible to rotate the print cylinder relative to the central drum. In a printer comprising more than one print cylinder, such movement of one of the print cylinders will cause relative movement of that print cylinder relative to the second print cylinder. Such movement may be used to bring the two print cylinders into register with one another.
- Advantageously, the gear housing comprises a worm wheel, and the gear housing adjuster comprises a worm threadably engageable with the worm wheel of the gear housing.
- The worm may be operated by any desirable mechanisms such as a control knob. Operation of the control knob will cause rotation of the worm which in turn will cause rotation of the gear housing.
- Advantageously, the print cylinder comprises an output shaft, and an input gear attached to the output shaft, which input gear is engageable with a plurality of planet gears which in turn are engageable with a ring gear enclosed within the gear housing.
- The invention will now be further described by way of example only with reference to the accompanying drawings in which:
-
Figure 1 is a schematic representation of a printer according to an embodiment of the invention; -
Figure 2 is a schematic representation of a part of the printer ofFigure 1 ; -
Figures 3a ,3b and 3c are schematic representations of an ink cartridge according to an aspect of the present invention, forming part of the printer ofFigure 1 ; -
Figure 4 is a sliced view of the ink cartridge ofFigure 3 ; -
Figure 5 is a schematic representation of a part of the printer ofFigure 1 showing the ink cartridge ofFigure 3 mounted in an adjustment mechanisms; -
Figure 6 is a rear view of the printer ofFigure 1 showing two gear mechanisms according to an aspect of the invention; and -
Figures 7 to 9 are schematic representations of one of the gear mechanisms shown inFigure 6 . - Referring to the Figures, and initially to
Figures 1 and2 , an embodiment of a printer according to the present invention is designated generally by the reference numeral 2. The printer 2 is particularly suitable for printing images in the form of text or other graphics onto a continuous strip of textile material. The continuous strip of material to be printed is fed onto the central drum, and once printed, will be cut to form individual labels for attachment to garments. The labels will typically indicate washing instructions and material composition of the garment to which they are attached. - The printer comprises a front plate 3 and a
back plate 5. - The printer comprises a
central drum 4 rotatable about a central shaft 6, and twoprint cylinders 8. Associated with eachprint cylinder 8 is ananilox roller 10. Each of the print cylinders will transfer an image in a particular colour onto the strip of material. In this example, printer 2 comprises twoprint cylinders 8 in order to print two colours onto the material. However, if more colours are to be printed onto the strip of material, the printer 2 would have more print cylinders. Similarly, if the material is to be printed with one colour only, the printer would have a single print cylinder. - The
printer cylinder 8 is supported between the front plate 3 andback plate 5 by means of the central shaft 6 which is attached to eachplate 3, 5. - The
anilox roller 10 associated with each print cylinder forms part of anink cartridge 12 shown in more detail inFigures 3a ,3b ,3c and4 . Thecartridge 12, in addition to theanilox roller 8, comprises a chambered ink duct 14, comprising ahopper tray 15 into which ink may be poured either manually, or by an automated process. In order to print an image having a particular colour onto material passing around the circumference of thecentral drum 4, theprint cylinder 8 is rotated as the central drum rotates, causing the material to be printed to pass between thecentral drum 4 and theprint cylinder 8. Theanilox roller 10 is also rotated, causing ink contained in thehopper tray 15 to be transferred onto the surface of the anilox roller. The surface of the anilox roller is formed with small engraved cells which enable the anilox roller to retain a predetermined amount of ink in the indentations. The size of the cells may vary from roller to roller, but typically will have a diameter of between 5 and 50 microns. - The
print cylinder 8 andanilox roller 10 are positioned so that, in use, theanilox roller 10 is in contact with theprint cylinder 8, and theprint cylinder 8 is also in contact with thecentral drum 4 or, in use, with a material to be printed. In addition, each of thecentral drum 4,print cylinder 8 andanilox roller 10 comprises adrive gear drum drive gear 60 and the printcylinder drive gear 62 will engage with one another. The printcylinder drive gear 62 will also engage with the aniloxroller drive gear 64. This ensures that rotation of thecentral drum 4,print cylinder 8 andanilox roller 10 is synchronised. - As the
central drum 4,print cylinder 8 andanilox roller 10 rotate, ink from thehopper tray 15 transfers to theanilox roller 10, and then to theprint cylinder 8. The surface of theprint cylinder 8 is contoured so that when the material passes between the central drum and theprint cylinder 8, an impression is transferred onto the material. - The positions of the
print cylinder 8 and the anilox roller can be adjusted relative to one another and to thecentral drum 4 as will be described in more detail below, in order that a predetermined level of pressure is applied by thecentral drum 4 and theprint cylinder 8 onto material passing over thecentral drum 4, and between theanilox roller 10 and theprint cylinder 8. - The
ink cartridge 12 further comprises an attachment for allowing removable attachment of thecartridge 12 to the textile printer 2. In this example, the attachment comprises afirst attachment portion 18 extending from afirst side 20 of thecartridge 12, and asecond attachment portion 22 extending from asecond side 24 of thecartridge 12. Each of theattachment portions attachment rollers 26 which are receivable within a roller receiving portion of printer 2 as will be described in more detail hereinbelow. - The
cartridge 12 also comprises an anilox roller adjustment in the form ofscrews 28 for adjusting the position of the ink roller relative to the chambered duct. - The
cartridge 12 further comprises atray 30 for collecting any ink not adhering to the surface of theanilox roller 10. - The printer 2 further comprises a print cylinder adjuster 32 in the form of a pair of spaced apart retaining
arms adjustment arms - The print cylinder adjuster 32 further comprises receiving portions 38 for receiving the
print cylinder 8, and also for receiving the attachment rollers of theink cartridge 12. - The
arms print cylinder 8. When thecartridge 12 and theprint cylinder 8 are each held in position by thearms central drum 4,print cylinder 8, andanilox roller 10 will all be substantially parallel to one another. - The
adjustment arms back plate 5 respectively, at pivot points 67, 68. The print cylinder adjuster 32 further comprisesclamp 69 operated by apneumatic cylinder 40 forming part of arespective arm print cylinder 8 is to be positioned relative to thecentral drum 4, the print cylinder will be positioned betweenadjustment arm 34, 35 in receiving portions 38.Print cartridge 12 will also be positioned between thearms - Once the
print cylinder 8 and theprint cartridge 12 are in position between thearms clamp 69 will be caused to move towards theprint cartridge 12 engaging with theattachment rollers 26, causing theink cartridge 12 to bear down onbearings 70 of theprint cylinder 8. - In order to adjust the position of the print cylinder relative to the
central drum 4, and thus to control the pressure exerted on the central drum by theprint cylinder 8, the position of the print cylinder may be adjusted by means of impression adjuster screws 42. Thescrews 42 are connected to rods 71 which are each operably connected to arespective arm - Each
adjustment arm respective arm 34, 35, by means of apin 72 retained in aslot 73. Movement of thearms - Each of the
arms first end 42 and asecond end 44. The second ends 44 of each of thearms central drum 4. This means that each of thearms print cylinder 8 is approximately the same as the length of thecentral drum 4 and theportions 40 are positioned so that when acylinder 8 is held in position between theportions 40, sides 46 of theprint cylinder 8 are coplanar with sides 48 of thecentral drum 4. - When it is desired to replace the
print cylinder 8 in order to, for example, clean the cylinder, or replace the cylinder with a different cylinder having a different diameter, for example, it is necessary to first to remove theink cartridge 12 by sliding the ink cartridge along thearms central drum 4 and then to remove theprint cylinder 8. When thecylinder 8 is replaced, or a new cylinder is positioned between thearms print cylinder 8 by adjusting theadjustment arms arms pneumatic cylinders 40, and clamp 69, print cylinders of different diameters may easily be positioned correctly relative to thecentral drum 4 since once aprint cylinder 8 is positioned within thearms print cylinder 8 is retained betweenarms adjustment arms impression adjuster screw 42. This in turn results in movement of the print cylinder andprint cartridge 12 in a direction either towards or away from the central drum 6 in a direction that is substantially perpendicular to the axis of the central shaft 6. - In the illustrated example, the printer 2 comprises two
print cylinders 8 each with an associatedanilox roller 10. The printer 2 is therefore set up to print two different colours on to a continuous strip of material extending round thecentral drum 4. - It is therefore necessary to ensure that the two
print cylinders 8 are in register with one another. If the two cylinders are not in register with one another, the two colours will not be appropriately positioned relative to one another in the image to be printed onto the continuous strip. - Each print cylinder comprises a print
registration adjusting gearbox 50 that extends through aback plate 5 of the printer 2. - The print registration
adjusting gear box 50 comprises an outer casing 54 enclosing aninput gear 56 attached to anoutput shaft 57 of theprint cylinder 8, and planet gears 58 orbiting the input gear. In addition the gear box comprises aring gear 59, and the planet gears 58 are in engagement with the ring gear. An outer surface of the casing 54 is gearcut to form a worm wheel. Thegear box 50 further comprises aworm 60 threadably engageable with the threaded outer surface of thegear casing 50. - In order to ensure that the two
print cylinders 8 are in register with one another, it may be necessary to rotate one or both of theprint cylinders 8 relative to thecentral drum 4 and also to theother print cylinder 8. In order to rotate a print cylinder in this way, theouter casing 50 associated with theparticular printer cylinder 8 is rotated by turningknob 62 which causes theworm 60 to rotate. Due to the threaded engagement of theworm 60 and thecasing 50, rotation of the worm causes corresponding rotation of the outer casing. - When the outer casing is rotated, the planet gears 58 will move with the outer casing and will cause rotation of the output shaft of the
print cylinder 8 through their engagement with theinput gear 56 and thering gear 59. The adjustment may thus be carried out without having to move the print cylinder away from the central drum. - By means of the gear mechanism of the print cylinder, it is possible to rotate the
print cylinder 8 by a small measured amount in order to ensure registration between theprint cylinders 8.
