Definitions

  • the invention relates to the field of ink-jet printers used for colour, printing of large format articles used, in particular, in the advertisement industry.
  • a specific feature of the utilization of ink-jet printers used for colour printing of large format articles is the production of large size images (up to tens of square meters) of sufficiently high quality at relatively low cost, which is attained by creating highly-productive machines with relatively low resolution of the produced images (usually 18-36 lines per inch). In a principle respect these devices are not distinctive over ordinary printers that are widely used as documenting devices in personal computers (PC).
  • PC personal computers
  • a typical representative of such devices is an ink-jet printing head and a printer comprising a paper feeding device, a carriage executing reciprocal movement along a paper substrate, and a removable jet head with a reserve of ink that is mounted on the carriage (EP, A2 0400652, 1990, B 41 J 2/07).
  • the head is made in the form of an autonomous unit having an electronic unit in which information relating to the mutual positioning of the drawing nozzles in the head is entered. These nozzles are used by the control program of the PC when information is fed from the PC to the printer.
  • the process of drawing is carried out by supplying energy to each nozzle of the head in the form of an electrical pulse which is converted into heat sufficient to discharge a portion of ink from the nozzle. Furthermore, a system for synchronizing the position of the head relative to the substrate and the information being presented is used in the printer.
  • an intermediate unit for storing the information to be applied makes it possible to separate in time the generation of images in a PC (for example, by scanning photographic images and then editing them, or producing images by machine graphic methods, etc.) and their transfer to the substrate. Furthermore, the volume of the information stored in the device only depends on its own capabilities and is in no way related to the PC, which makes it possible to use this device in network systems.
  • ink cartridges directly on the carriage simplifies the construction of the device, ensuring at the same time the possibility of obtaining a larger volume of graphic material without frequently recharging the device.
  • an intermediate service cartridge ensures a constant level of the ink, which promotes effective operation of the jet elements and a high quality of the images being reproduced.
  • a device serves to obtain a direct image on one side of a sheet and a mirror image on the other side, which makes it possible to obtain a high quality image on a semi-transparent material (US, A 5376957, 1994, B 41 J 2/045).
  • This device is provided with an ink-feeding mechanism with two carriages positioned on opposite sides of a substrate. Control of the operation of the device and, in particular, the carriages and heads, is carried out with the aid of a unit for control and storage of the direct and mirror images being formed.
  • a scanner By means of a scanner, information is entered into a computer which edits the image and encodes the print density of each colour in the form of electrical current pulses of different width, which control electric valves of the atomizers of the jet heads of each colour, which are on the ink-jet printing device.
  • the density of each colour is determined by the width of the pulse generated by the PC.
  • the air stream entering the working nozzle of the jet element consists of two streams: one - continuous, creating a constant stream of air in the nozzle, which ensures that the ink in the supply channel does not dry and hinders the formation of parasitic drops at the end of that channel, and the second - controlled with the aid of an air valve which opens an additional stream of air, ensuring the supply of ink to the substrate in accordance with the width of the control pulses.
  • the substrate is heated with spiral heaters which are mounted below and above the carriages in the direction of movement of the substrate. Sponges are also disposed on the carriages, the sponges wiping the substrate before the ink is applied thereon, this ensuring removal of foreign contaminants and also enhancing application of the ink onto the substrate.
  • Reciprocal movement of the carriages presumes acceleration to the nominal speed, braking and stopping for each working cycle, which reduces the productivity of the device and requires increased power of the drive mechanisms and corresponding braking dampers. Furthermore, with horizontal positioning of the heads of different colours from the left to the right and from the right to the left, the sequence in which the primary colours are applied is disturbed, which results in "striping" (by shade) of the obtained images. There is also a problem in obtaining quality two-sided images, the solution to this problem not being found in prior art. In particular, different heads, positioned on different carriages, are used in the making of direct and mirror images. It is virtually impossible to ensure their complete identicality in operation. Therefore, when two-sided images are being produced, distortions inevitably occur in the colour reproduction, and this affects the quality of the article.
  • a large format ink-jet colour printer which comprises a substrate feeding system, an ink feeding mechanism which is movable along a closed guiding rail relative to the substrate, this making it possible for heads to travel around the substrate on two sides, and a printer control unit.
  • Shafts in the substrate feeding system are positioned in a vertical plane, wherein tensioning shafts, connected to reversible motors by means of magnetic clutches, are positioned above and below the feeding shaft provided with a reversible motor.
  • the ink feeding mechanism movable along the closed guiding rail is provided with at least one carriage with brushes for supplying electric power, with a receiver to be filled with air from an external source by means of a rapidly-released catch, with a controller provided with a transceiver, and with an optical sensor electrically coupled to the controller.
  • the guiding rail is provided with busbars for supplying electric power and with a hatched ruler for exactly positioning the carriage.
  • electrical valves connected to the printer control unit are mounted between the charging cartridges, positioned on the carriage and having a level sensor, and the rapidly-released catches of the system for recharging those cartridges. The rapidly-released catches are positioned in places where the guiding rail turns.
  • the carriages move at a constant speed, which reduces the power of the drive mechanisms and eliminates the need for dampers, since movement of the carriages takes place in one direction (for example, in the clockwise direction), removes the question of "striping" in the obtained images, and the colour palette of the direct and mirror images is also the same. Wherein, full autonomy of the carriage is ensured upon its movement over the working sections of the substrates.
  • the printer may have a second substrate feeding system, independent of the first, wherein both parallel positioned substrate systems are encompassed by the closed guiding rail.
  • a second substrate feeding system independent of the first, wherein both parallel positioned substrate systems are encompassed by the closed guiding rail.
  • FIGS 1, 2, 3, 4, 5 illustrate the construction of the device.
  • the large format ink-jet colour printer (Fig. 1) consists of a frame (1), rollers (2) for feeding a carrier, tensioning shafts (3), a feeding shaft (4), guiding rollers (5), pressing rollers (6), a receiving shaft (7), a carriage (8), a guiding rail (9).
  • the tensioning shafts for the substrate are connected to reducers (11) and reversible electric motors (10) by means of magnetic clutches (12).
  • the shafts for receiving and feeding the substrate are connected to reversible drive electric motors via reducers (not shown in Fig. 1).
  • the carriage (8) (Fig. 2) is placed on the closed guiding rail (9) to which copper busbars (14) are secured by means or supports (13) made or a nonconductor.
  • the ink feeding mechanism is shown in Fig. 3.
  • an electric drive control unit (20) for communication over a radio channel with a control unit (not shown in the Fig.) and for ensuring operation of all units of the carriage in the process of developing images
  • an optical densor (22) for positioning the carriage relative to the substrate along a hatched ruler (23) positioned on the guiding rail
  • a brush holder (24) with brushes (15) for supplying power to the carriage are disposed on the carriage (8).
  • Diagrams showing the positioning of rapidly released connectors used to recharge the carriages with air and ink are shown in Fig. 4.
  • the air recharging system includes a pipe (25), a supply coupling (26) with a movable tip (27) sitting on the coupling with the possibility of rotating thereon, a carrier (28) on which a rapidly-released catch (29) for butt-joining and disengaging with a pipe (30) for charging the carriage receiver is secured. In the initial position the carrier (28) is held by a spring (31) secured on the movable tip (27).
  • the ink recharging system is set up in a similar manner, except that ink charging electric valves (33), connected to the charge cartridges for the ink (19), are mounted on a carrier (32).
  • Rapidly-released catches (34) are secured to a lower (output) part of the electric valves (33) and during the recharging are located opposite the necks of the charging cartridges (19) and the assembly of heads with cartridges for ink (18), which are disposed on the carriage (8).
  • the device operates in the following manner.
  • the feeding shaft (4) moves the substrate one working step equal to the width of a line of the image being produced.
  • the controller (21), disposed on the carriage enters the working zone in the process of movement of the carriage, it effects autonomous control of the process of putting the information (in this case by operation of the jet elements) onto the substrate.
  • the control unit of the device determines the condition of the device, effects control of the operation of the air and ink recharging systems, effects movement or the substrates, carries out additional servicing actions, determines the working capacity of the device, tests separate units, brings out a message to the operator onto the reproducing system and effects the subsequent operation cycle.
  • the device in accordance with the described algorithm may effect the structuring of images from two sides, both with the aid of one carriage and with the aid of two or more, and where there are two independant systems for feeding substrates, the device has the possibility of effecting the structuring of images on two substrates.
  • the general diagram of a device with two systems for feeding a substrate and with two carriages is shown in Fig. 5.
  • the proposed technical solution makes it possible to create large format printers for producing printed articles, in particular, in the production of outside advertising objects.
  • Realization of this invention enhances the quality of a produced article (i.e. the quantity of an image) and increases the productivity of printers by at least two times.
