Abstract
The present invention pertains to the field of ink jet printers used for colour printing of large format articles. This invention is used for improving quality and for increasing the yield of printers and comprises successively applying primary colours, suppressing colour aberrations when printing a semi-transparent material on both sides, precise ly positioning the head when printing an image on the substrate and eliminating the lines connecting the carriage to the systems supplying control signals, air and inks. To this end, the carriage with the jet heads is moved in one direction along a closed guiding rail which is fitted with a hatched ruler for precise positioning, wherein the heads will thus bypass the substrate on both sides while information is transmitted fro m the device control unit to the carriage using a radio transceiver. The printer can further be equipped with two independent and parallel substrate feeding systems for performing a one-sided printing on two substrates at the same time.
Description
LARGE FORMAT INK-JET COLOUR PRIr.ITER
Field of the Invention The inverition rE~iates to the field of ink-jet printers used for colour printing of large format articles used, in particular, in the advertisement industry.
Background Art A specific feature of the utilization of ink-jet printers used for colour printing of large format articles is the ;producaion 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 riot distinctive over ordinary printers that are widely used as documenting devices in personal computers (PC) .
typical re~reser~tative of such devices- is an ink-jet printing head and a printer cornpri~ing a paper feeding device, a carriage executing reciprocal movement along a paper substrate, and a removable jet head with a reserve of ink that i~a mounted on zhe car_wiage (EP, ?~2 X400652, 1990, B 41 ,T 2/07) . The head is made in the form of an autonomou:5 unit having an electronic unit in which information relating to the mutual p ositioninu of the drawing nozzles ir: the head is entered_ these ,.
nozzles are used by the control program of the PC when-information is feed ~ro:m the PC to the prir_ter .
The prOCesS Of drawing is carried out by supplying energy to each ;ZOZZle~ of the head in the form of an S electrical pulse which is ccnverted into heat sufficient to discharge a portion of ink from the nozzle.
Furthermore, a system for synchronizing the position of the head relativ~s to the substrate anti the information being presented is used in the printer.
From a principlsa point of view, all printers operate according to t:zis arrangement,. differing only by the method of applying the image (eithe~~ by heat, or hydraulic impact, or b.Last of air, etc _ ) _ z~ll of the basic: elements of such printers are present in the device: disclosed in the patent US, A
4999651, 1991, G Ol D :15/16. In a colour recorder, in k cartridges are positioned on a common carriage that effects reclproc_al mo~rement. There are also intermediate wor~:ing cartridges in which the level of the ink is maintained virtually constant, which ensures the highest quality of the ~mages being reproduced.
Furthermore, the device contains an electronic unit which holds the i:magn b eir_g reproduced in its memory and controls the oper~~tion modes of Lhe device.
The presence of ein intermediate unit for Stori.rig the information to be applied makes it possible to separate in time the generation of images in a PC (for example, by scanning photographic imagas and then Editing them, or producing images by machine graphic methods, etc.) and their transfer to tr.e substrate.
3 _ Furthermore, the volume of the informzstior: stored in the device only depends or~ its own capabilities and is in no wc~y related to the PC, which makes it possible to use this device in network systems.
The presencE~ of ink cartridges d~~ectly on the carriage simplifies t;he construction of the device, ensuring at the same tame the possibility of obtaining a larger volume of graphic material without frequently recharging the device., As already noted above, the presence of an intermediate service cartridge er_sureS a constant level of the ink, which promotes effective operation of the jet elements and a high duality of the images being reproduced.
A device is known that 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 or.~ a semi-transparent material (US, A
5376957, 1994, B 41 J 2/095) . This device is provided with an ink-feeding mechanism with two carriages 2o positioned on opposite sides of a substrate. Control of the operation of tree device and, in p~.rticular, tr.e carriages and heads, is carried out with the aid of a unit for control and storage of the dire~~t and mirror images being formed. Hy means of a Scanner, ?S information is er..tered into a computer wh ich edits the image and encodes> the print density of each colour in the form of els:ctrical current pulses of different width, which control e7_ectric valves of the atomizers ef the jet heads of each colour, which are on. the ink-jet 30 printing device. Thus, the density of each colour is ~.
determined by the - width of the pulse ge_zerated by the FC. Specific features of the operation of ink-jet e-~ements of the heads are that the air stream entering the working nozzle of the jet element consists of twe S streams : one - continuous, creating a cor_stant s Cream of air in the nozz7_e, which ensures that the ink ir: the supply channel does not dry and hir_ders the formation of parasitic drops at the end of that channel, and the seccnd - controlled with the aid of an air valve which cpens ar_ additional si~ream of air, ensur=ng the supply ef ink to the substrate in accordance with the width of the control pul;;es. In order to ensure reliable adhesion arid drying and to exclude smearing of the ink, 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 ~~hereon, this ensuring removal of foreign contaminants and also enhancing application of the ink onto the ~ubstrate.
However, ths~ presence of lines in each moving car riage should be noted in This construcv.ion . These lines consist of a plurality of electrical cables, for control of the valves in the heads, amd tubes for feeding zhe ink. Th:~s line increases as the width of the substrate, along which the carriage moves, increases, and this line has to move toge~:.her with the carriage, which creates a number of technological difficulties and :reduces the reliability of operation of the device. -_ 5 -. Reciprocal movement of the carriages presumes acceleration to ~~he nominal speed, braking and stopping fox each working cycle, which reduces the productivit y of the devioe and requires increased power of the drive mechanisms and corresponding braking dampers.
Furthermore, with horizontal positioning of the heads of different colour;; from the left to the right and from the right to the left, the sequence in which the primary colours are applied is disturbed, whiciZ results in "striping" (by shade) of the obtained irnag8s. There is also a problem in obtaining quality- two~sided images, the solution. to this problem not being found in prior art. In particular, dzfferen~ heads, positioned on different carriages, a re used in the making of d~.rect ar.d mirror image's . It is virtually impossibly to ensure ~cheir 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:.
Disclosure of the Invention The problems be:W c~ solved in the invention are the fcllow.ing:
- liquidatio:n of the lines connecting the carriage to the systems for supplying control signals, air and ink:
- ensure the suc:Cessive application o- the primary colours - suppression of colour aberrations where printing -a semi-transparent substrate on both sides:
- ensure the precise application of the ink onto the substrate;
- ensure the possibility of simultaneously performing one-sided printing on two substrates.
In order t o achieve the aforesaid technical results, the construction of a large format ink-jet colour printer is proposed which comprises a subsi:rate 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 con trol unit. Shafts. in the substrate feedi.zg system are positioned in a vertical plane, wherein tensioning shafts, connected ._o reversible motors by means of magnetic clutches, are positioned above ~~nd 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 rE~eiver -~o 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 ?5 coupled to the contr oiler. The guiding rail is provided with busbars for supplying elect=is power and with a hatched ruler for exactly positioning the carriage. Wherein, 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. In order to increase the productivity there may be two and more of such carriages. 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. Thus, an image may be obtained simultaneously on two substrates which are inside the closed guiding rail, this substantially expanding the consumer properties of the device and enhancing its productivity.

at least one ink feeding mechanism that is movable along a closed guiding rail for moving relative to a substrate;

Hest Method of Carrying Out the Invention The large format ink-j et colour printer ( Fig . 1 ) consists of a frame (1) , rollers (2) for feeding a carrier, tension=~ng 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 mcvtors (10) by means of magnetic clutches ( 12 ) . Th~a shafts for receiving and feeding the substrate are connected to reversible drive elec:tz:ic motors via r~ducExs (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 of supports (13) made of a nonconductor. Electrical current is applied to the busbars. By means of brushes (15), electric current is applied to the power supply of the carriage (not shown in the Fig.) and to other power consuming devices. The ink feeding mechanism i.s shown in Fig. 3. A:~ electric drive ( 16 ) f or ensuring movement of the carriage ( 8 ) , a receiver (17) for storing high pressure air for ensuring operation of the jet elements, an assembly of heads (18) with jet elements and charge cartridges (19) for storing ink with level sensors (not shown in Fig. 3), an electric drive control unit (20), an electronic controller (21) 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 sensor (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 connections 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 arm (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 arm (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 i0 .
charging cartridges (19) and the assembly o' heads with cartridges for :ink (L8) , which are disposed or: the carriage ( 8 ) _ The device o~~erates in the following manner.
In accordance with commands from the control unit of the device, th.e feeding shaft (4~ moves the substrate one working step eaual to the width of a line of the image being produced, When the position of the carriage (8) in the process of its uniform movement is in the inoperative zon.e3 of the device ( Zones I and II, See Fig_ 2), recharging of the carriages with air and ink is Carried out, and also information, which should be reproduced on the substrate, is transmitted over the radio channel. When 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 o:f putt:ing the information (in this case by operation of the _jet elements) onto the substrate.

Gdhere there is one substrate present, 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 independent systems for feeding substrates, the device has the possibility of effecting the stew cturing of images on two substrates.
Tr.e general diagram of a device with two systems for feeding a substrate and with two carriages is shown in Fig. S.

- ensure the suc:Cessive application o- the primary colours - suppression of colour aberrations where printing -a semi-transparent substrate on both sides:
- ensure the precise application of the ink onto the substrate;
- ensure the possibility of simultaneously performing one-sided printing on two substrates.
In order t o achieve the aforesaid technical results, the construction of a large format ink-jet colour printer is proposed which comprises a subsi:rate 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 con trol unit. Shafts. in the substrate feedi.zg system are positioned in a vertical plane, wherein tensioning shafts, connected ._o reversible motors by means of magnetic clutches, are positioned above ~~nd 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 rE~eiver -~o 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 ?5 coupled to the contr oiler. The guiding rail is provided with busbars for supplying elect=is power and with a hatched ruler for exactly positioning the carriage. Wherein, 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. In order to increase the productivity there may be two and more of such carriages. 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. Thus, an image may be obtained simultaneously on two substrates which are inside the closed guiding rail, this substantially expanding the consumer properties of the device and enhancing its productivity.
