with several nozzle lanes, top view; in fig. 3 - the same, but with one strip of nozzles, forks on the side; in fig. 4 is a nozzle strip connected to an ink supply system and a pattern control unit, forked in & 5 - nozzle; in fig. 6 is a time diagram illustrating the sequence of actions of paint currents on pile tiles; in fig. 7 is a block diagram of electronic registration equipment; in fig. 8 is a flowchart of rice control; in fig. 9 is a timing diagram of a control pattern of a pattern; in fig. 10 is a block diagram of a control panel; in fig. 11 is a block diagram of one distributor of the pattern control unit; in fig. 12 is a block diagram of the control circuit of the nozzle run time; in fig. 13 is a block diagram of the control loop splitting. The installation for applying patterns to the tile tiles comprises a table 1, from which the pile tiles 2 are fed to the lower end of the inclined conveyor 3, where the tiles are painted using the programmed work of the Multiple Strips 4 nozzles 5. The tiles 2 are transported by conveyors 6 and 7, driven by The engines 8 and 9 move into the steam chamber 10, where the paints are closed with the painted tiles. The steam chamber 10 that has passed past, is pressed through the water sink 11 to remove excess loose red paint and then pass through the air DRYING 12 to the receiving unit. in table 13, where okr.ashennye tiles are added. The conveyor system may be used to move other materials, such as continuous or wide pile carpets. For an endless conveyor, 3 chains and sprockets (not shown) can be adapted to transmit rotational movement to shafts 14, 15. Shaft 15 is set in motion by engine 16. To paint carpet tiles 2 of rectangular OR square fiber, on the surface of conveyor 3 there are a number of separators of separators 17, which precisely position the tiles — at a certain distance of OTHER on the carrier plates of the conveyor. While the conveyor is moving, the tiles run successively under the same strips of 4 nozzles 5 (Fig. 5), five strips 4 are located at some distance from each other along the path of the conveyor and stretched across its entire width. FIG. Figures 3 and 4 show only one strip of 4 nozzles 5, with each strip of nozzles essentially having the same designs of nozzle holes 18, arranged along polo ct # and positioned so as to direct paint in the form of narrow streams. Each nozzle strip includes a paint supply manifold 19. (FIG. 3) connected to the nozzle holes 18. In the collector 19, the liquid ink comes from the collection / collection of Torah 20 for the storage of paint. From collector-collector 20, pump 21 supplies liquid paint to collector 19 and nozzle holes 18. During operation, liquid paint is continuously displaced in the form of jets from holes 18 to the material to be painted. At right angles to the outlet 18 of each nozzle 5 there is a means for deflecting the flow of paint from the pile tile 2, which is a pipe 22 with an outlet 23 through which air is fed (Fig. 5), where the tube is associated with a separate mechanism controlling the means for diverting the flow of paint. The latter is made in the form of a solenoid valve 24 (figure 4). Solenoid valves pass air from the air compressor 25. Since each nozzle opening of each nozzle strip is equipped with a solenoid valve and an individual air supply, each paint flow can be individually controlled. The valves are controlled by a pattern control block 26, which causes the air flow to collide with continuously flowing paint streams and deflect them into the receiving bath 27, from which the paint is again directed through pipe 28 to the collector-collector 20. The pattern control block 26 includes a digital switching device with a storage device for a picture in the form of a magnetic tape (not shown in the drawing). In general, to print repeating patterns, the magnetic tape can be equipped with: repeated sequential information that is transmitted to the solenoid valves 24 until the desired number of tiles 2 are printed. In this case, a series of ten tiles can be placed at some distance from each other. a friend on the conveyor belt and the control unit of the pattern 26 will start to act as soon as the front leading edge of the first pair of tiles 2 is located under the first band 4 of the fsuncture 5. Then the information from the magnetic tape is entered into the switch unit 26 to set the solenoid valves 24 in the on or off position. Each solenoid valve 24 is normally in the open position for supplying air flow to collide with inadvertently flowing paint and deflect all of them simultaneously into a bath of 27 lanes 4 for subsequent return to the system.

As soon as the first pair of tiles passes under the first strip 4 of the nozzle 5 | And the pattern control block 26 is turned on, certain normally open solenoid valves 24 are closed, then the corresponding flows do not deflect, but fall directly onto the pile tiles 2. Thus, when switching in the desired dKe, in the off or on position of the solenoid valves 24 on the pile tiles 2, as they pass, a printed colorful pattern is obtained.

Continuous use of the paint device may slightly change the speed of the conveyor 3 transferring the pile tiles 2, which may cause the colorful patterns once placed on the tiles to not coincide with the material to be painted. A device is provided for adjusting the position of the conveyor with a starting point for signals from the pattern control unit to the air valves.

The control system includes a synchronous switch 29, a converter 30 and an electronic recording system 31. The switch 29 periodically interlocks with the finger 32 of a mechanical switch mounted on the edge of the conveyor 3, while the converter 30 is operatively connected to the shaft 15 to convert the mechanical movement of the conveyor 3 into electrical impulses normally sent every millimeter.

Converter 30, which may be mechanical, optical or electromagnetic, is mechanically connected; it is connected to shaft 15 through gear 33 to obtain the desired number of pulses per centimeter of movement of the conveyor 3. In the present example, converter 30 has such a transmission to send 10 electric pulses per centimeter of the way.

The signals from transducer 30 come through electronic recording system 31 to control block figure 26, when conveyor 3 moves tiles 2 past 4 nozzle strips 5. The activation signals of individual streams of stripe 4 nozzles 5 to the pile tile 2 are sent after tile 2 reaches a certain , a pre-selected distance relative to the position of the strip 4 nozzles 5. Usually, if it is desirable to put a pattern on a pile tuft carpet, having a series of tufts that are 2.5 mm apart from each other, both in transverse and and in the longitudinal direction, the spacing of holes 18 -4 strip 5 between the centers of the nozzles must be 2.5 mm, and a registration system for signal | actuation pattern control unit should send a signal to the four set centimeter path of the conveyor 3.

The pattern control unit has a means of applying ink streams to the pile fabric at selected intervals during the time interval corresponding to the 2.5 mm conveyor movement path. As soon as the pattern control unit (FIG. B) receives the setting signal E from the recording system 31 /, it sends command signals to close the selected air valves and paint on the pile carpet with the corresponding dye flows.

The length of time that any of the air valves can remain closed (thereby ensuring that the paint stream does not deflect air) can be varied within a period of time using a suitable device, such as an analog or digital software device.

The duration of the active period of time T, during which one of the selected valves 24 can act fixedly from the beginning of operation and equally during each time interval T, even if the time interval can vary. In a selected period of time, when the pattern control unit can send command signals by valve 24 of any strip 4 nozzles 5, the longest period of time, which can be chosen shorter than the shortest time interval I, and can have a value during each interval р this time Q. The Q. time satisfies the valve response rates, the electronic time relay setting error, and the conveyor speed changes.

For example, the conveyor and nap fabric can be moved at such a speed that the setting signals are sent to the pattern control unit at nominal intervals T equal to 82 ms. The fixed time period T within this interval, during which dye can be applied to the nap fabric, is set to 25 milliseconds, with actual application times within this period programmed for the operating cycle / on / off. The time period T may be divided into a number of time intervals, for example, 31, and a signal may be sent to each air valve so that the valve can remain closed for a selected number of such time intervals C, which is the operating time, Included. Values which valve 24 is open for -,) tilt (paint flow, will turn off the operating time in the time period. The 5th advantage is when it is desirable to mix paints from different strips of 4 nozzles 5 in place. E If two strips of 4 nozzles 5 initially contain blue and yellow paint, different shades of green color can be obtained by sequential application of paint to the same place on the carpet, i.e. a small amount of paint from one strip of nozzle that produces a current of blue paint and a small amount of paint from another strip of forms of cyfrOK, injecting a stream of yellow paint. -, IF you do not mix on the spot while painting, and the paint is produced when applying the desired colors in selected areas from a single strip of A drawing containing the desired color that is selected for action can remain closed for the entire time period T. The length of the time period must be chosen before Yachala is based on the character of nap fabric, in ffOCtH and the speed of the outflow of paint, etc. . to ensure that the amount of paint applied to the fabric is sufficient to completely cover the desired strand or strand to the base without being impregnated or flowing into adjacent areas. The specific size and distance between the holes 18 of the nozzles 5, the viscosity of the paints used, the amount of paint applied to a specific pile of fabric, etc. can be varied depending on the individual characteristics of the underlying color. The experience of applying patterns to pile fabrics shows that the desired results are achieved for carpets having a specific weight and pile height in the range of from 15. to 45 ounces per square meter (from 500 to 1500 grams per square meter) and from 0.125 inch to 1.5 inches (from 3.3 mm to 3.8 mm), respectively. The nozzle 5 should be located at a distance of 2.5 to the size of the holes 18 from 0.25 mm to 0.65 mm (with a ratio of the diameter of the nozzle to its length from 5 to 13). In addition, it was found that when staining tfdspOB, a high ratio of S on the bottom is obtained with colors from 50 to 1000. The pressure in the paint streams can vary from 8 to 15 pounds per square meter 1) (from 0.56 up to 1.05 kg / cm). The exact time intervals T between the unlocking signals E, the time periods T, during which they are from the unit

8 1 of the pattern control signals can be sent to the valves 24, and constant periods of time Q in the operating cycle can vary depending on many parameters, for example, Carpet speed, density and type. tufted in carpet, from VISCOSITY and applied paint pressure, from minimum valve switching speed, etc. The dyeing machine was also used to apply patterns to nap fabrics moving at a speed of 9 M / ceKf with a 300 | -unity increase, which weights compared to the weight of the nap threads due to liquid dye. The time interval between the trigger pulses E must be 16.5 milliseconds. The time period T, during which signals can be sent to start operation of the injectors 5, should have a duration of 15 milliseconds, leaving a constant Q period of 1.5 milliseconds. This will ensure a minimum amount of time constant, depending on the valve response time, equal to 1.5 milliseconds (the response speed of the air valves), provided that the valves must be in and off during the entire on-off period of time T. Preferably 9 takes, at least, at least about 5% of the size of the entire interval I between the trigger pulses. As mentioned earlier, the nap fabric 2 moves along a sloping path during the application of paint streams. The used angle of inclination is chosen so as to obtain an equilibrium between the harmful effect of gravity on the directional flow of paint and the scattering of small particles of paint after it is applied to the pile surface while maintaining a sufficient distance between. 4 nozzles 5 and a nap surface provided that under the force of gravity the outflow oV of the recirculation catching bath 27 nozzles 5 to the carpet 2 is performed. It is advisable to use nakloi angles from 15 to 50 from the horizontal, while the 25 ° angle is optimal . Synchronous switching off, the telegraph 29 of the recording syrtem 31 is triggered by using finger 32 of switch 33 as soon as the first carpet tile 2 on conveyor 3 reaches the strip of 4 nozzles 5 and triggers 34.35 and counters blocks in the comparator counters 36 returns to their original position. 37.38. Each pulse from the converter 30 causes the trigger 34 to begin transmitting oscillations from the synchronizer 39. The pulses from the synchronizer 39 arrive at the comparator counters 36 and 37

Comparison block comparator

36 is manually set to a number (shown on the adjustable; manually numeric indicator 40, like 10), which allows this number of pulses from the synchronizer 39 to enter the comparators 36 and 37 before the blocks of the counter 36 and trigger 34 return to their original position, thereby oscillation synchronizer 39.

 The comparison block of the counter-compressor 37 is set to a number (shown on the manually adjustable digital indicator 41, as 25), which allows this number of pulses from the UT-39 to enter the counter 37 block before applying a pulse from the comparator counter 37. This pulse is CJfnaeT to the counter-comparator 38 back to set to the original position of the counter-comparator

37 and to the control unit of pattern 26. When a pulse arrives from the 1K-comparator score 37, block 26 sends one of the pattern signals stored in it to instantly turn on one or more solenoid clathgans 24, which allow

 If the corresponding paint streams hit carpet tiles 2. When the counter-comparator 38 receives a certain number of pulses from the counter-compass 37 (shown on a manually adjustable digital indicator 42, like 980), it sends a signal to the trigger 35 to set it on and off addition valve. 43, preventing further transmission. These signals or impulses to the control unit of the pattern of the comparator counter 37. This setting of the indicator 42 is selected in accordance with the number of tiles or the length of the tile 2, painted during one cycle of operation of the control block 26 of the pattern.

The number of pulses per centimeter sent by transducer 30 is multiplied by a counter-comparator 37. The impulse ratio (per centimeter) is taken with a factor of 10/15. This Ratio can be set by adjusting the indicators 40 and 41 so that the pattern matches exactly with the tiles 2. Thus, the coefficients can be corrected when the conveyor 3 is worn.

The main control panel 44 has an input 45, connected to the computer 46, an input line 47 from the electronic recording system 31 and has an output along the lines; 48 to the calculating machine 46. The control panel 44 has eight additional outputs connected respectively via electrical conductors 49 to eight distributors 50. The eight strips of 4 nozzles 5 are connected respectively to the distributors 50 via m or 51 and each includes se t

, connecting pZhIyel 52 strips of 4 nozzles 5, connected to the board 53 soyoil Gdpaya 24 through the conductor 54.

Each BOC: E MI 4 forsuno 5 strips includes 1560 nozzles, controlled by 1560 solenoid valves. The picture information supplied from the solver-decider 46 is a group of 8x1568 bits and clock pulses.

When the conveyor 3 is moved 2.5 mm, the electronic recording system 31 sends an unlocking impulse to the control panel 44, to Topai 3afeM 3anp FH eaeT from the number-solving machine 46 one of the groups of picture data. After this, a sequential flow of information containing information about the drawing and synchronizing pulses, which are fed through line 45 to the control panel, starts from the computer. 44.

The control panel 44 decomposes the information and synchronizing clocks Iraks1 :: vmr) G568 bits, each of which transmits 1 edn1i from eight distributors 50. The first 1560 bits in each group relate to the picture information for each of the 1560 nozzles in the strip 4 nozzles 5 / while the last eight bits or syllable are not used in the normal cycle mode.

The control panel 44 may include two lines 55 and 56, through which information about the figure and the synchroaire is obtained from the calculating machine 46. The clock pulses are applied to the first decryptor 57-. The information in Figure 6 is transmitted to the second decoder 58.

Decoders 57 and 58 from address counter 59 through lines 60 and 61 receive address information and route the received bits to eight appropriate allocators on line 62.63 in accordance with the information addresses. The address counter 59 performs its own midrange: as a certain number of synchronization pulses go to panel 44 to identify lines 62.63, and the same delivers a certain number of information bits and synchronization pulses to each of these lines. In order to perform unit counting, the address counter 59 of line 56 is also connected to a single-stable multivibrator 64, the output positive impulse of which is fed to a counter 65 counter. When the comparator counter 65 counts to a constant number, the output pulse is transmitted to the vein | TilNE-I 66, the other input of which is connected to the multivibrator 64. The output of the valve 66 is connected to the counting input of the address counter 59 for a sequential counting by one. When the counting machine 46 no longer receives synchronization pulses, indicating that all the information about the drawing has arrived, then the counter 59 returns to its original position. Thus, line 56 is also connected via line 6-7 to a newly unlocking multivibrator 68, the OUTPUT of which is connected to the main input of the counter 59. The multivibrator 68 continuously unlocks and thus does not provide a negative output signal (restoring the original position) until sync-synchronization impulses are no longer received at its input. Moreover, the counter 65 returns to its original position after it has completed the specified count. Thus, the output of the valve 66 is also connected to a single-stable multivibrator 69. The output of a single-stable multivibrator 69 is connected to the non-OR 70 valve, the second input of which through the line 71 is connected to the output of the newly unlocking multivibrator 68. The output of the valve 70 is fed to the main restoration input in the original the position of the counter 65; The decoder 58 directs the received information through different lines 63 to feed to the corresponding distributors 50. The first 1568 bits (FIG. 9) of the serial information flow are directed to the first distributor, the second bit 1568 - a second distributor, and so on. In the end, the counter 59 will calculate one by one all 1568 sync bits. The decoder 57 is the same. In this way, it directs synchronizing pulses along lines 62 separately to each strip of 4 nozzles 5. Informator and synchromesh; 3; nozzles; syphonics are assigned to eight groups of 1568 bits each. The function X1 of each distributor 50 is to group each of the obtained groups into thirteen subgroups of 120 bits in each subgroup, each corresponding to a width of 120x2.5 mm, i.e. 1, the width of the conveyor 3 is used. T: the same technique for unfolding as in FIG. 10, and therefore not described in detail. Each of the two decoders (one for information and one for synchronization and Pulses have fourteen output lines 71 72 (Fig. 11 and 13). The first 120 bits are fed to the first output lines, the second 120 bits to the second lines, etc. The last eight bits information and synchronization from the group of 1568 bits received in one distributor are supplied to the fourteenth lines 71, 72 of two decoders. With information about the drawing and synchronization pulses for a strip of 4 nozzles 5, now grouped into thirteen groups of 120 bits each, the distributor 50 stored These bits in rows of thirteen groups of shift registers.Each register in the group can store four bits i, information about the drawing and therefore information received on any one line 71 from the information decoder (not shown, but briefly described), comes in thirty registers, 120 bits of the shift registers .In Fig. 11, only two registers 73,74 are shown. The first shift register 73 receives information via line 71, which is synchronized using synchronization pulses through line 72 and inverter 75. Each of thirty The shift register has four output lines 76 for each of the four stored bits, each connected to one input of four operational differential amplifiers 77, respectively. A fourth stage of the first shift register 73 is connected to the input of the second / shift shift register and so more to have the ability to enter 120 bits in thirty registers. Each of the operational amplifiers 77 has a second input connected to the selector line 78, applying an operating voltage through the amplifier output line 79 to the various solenoid valves 24 during a certain and variable start-up time in accordance with the information stored in the registers. For example, the four bits stored in register 73 represent a logical element O or i and can correspond to levels from 0 to +5 V. Each operational amplifier 77 sends a signal to the output depending on whether the voltage level is higher or lower. in line 76 as compared to the voltage level in the selector line 78. If the information bit voltage exceeds the voltage in the selector line, then only at the amplifier output there will be such a signal that the solenoid can operate, and the dye can get through the corresponding nozzle vy Cove. The duration of the switch on or the time of active work, set by the voltage of the selector line, will regulate the amount of dye applied to the carpet. In addition, during insertion of the bits in the shift registers, none of the solenoid valves will control the pattern information, therefore during this insertion a sufficiently high level of voltage in the selector line is provided to protect the amplifiers 77 from altering and triggering the solenoid valves.

FIG. 12 shows thirteen power devices 80 for solenoid valves, one for each of the thirteen groups of 120 bits stored in the valve 50. Each locking device includes an operational amplifier 81, whose input is connected to a manual switch 82 having contacts 83, 84 and 85. The input of each amplifier 81 is connected to a +3 V source, provided by five diodes 86. The other input of each amplifier 81 is connected via line 87 to the output of the НЁ-И 88 valve, whose one input is connected to a turn-off relay 89 of a strip of 4 injectors 5 and whose other the input is connected to the output of the multivibrator 90. From the output of the locking devices 80, a search is made for the selector line 78, which is connected to the operational amplifiers 77 of each of the thirteen groups of 120 bits.

When entering information, the re-unlocking multivibrator 91 continuously produces unlocking by means of synchronization pulses arriving on line 62. Corresponding to start-ups, the 1st multivibrator 90 is not unlocked. Therefore, the NOT-AND gate 88 is not open and the output of line 87 leading to the corresponding amplifier 81 will be maintain the voltage of +5 V. As this voltage exceeds the voltage of +3 V applied to the other input of the amplifier 81, the voltage at the output of these amplifiers will be +15 V. Accordingly, the voltage of +15 V will be applied through 78, through contacts 83.85 to one of the inputs of amplifiers 77. Since the voltages associated with the information bits do not exceed +5 V, operational amplifiers 77 cannot change state to open the solenoid valves information. In addition, a relatively high 15V voltage in the selector line 1 will prevent the amplifiers 77 from switching during information input due to noise in the circuit. Manual switch 82 can have its own contacts. 183 and 84 are closed for locking at a voltage of +15 V in the shift register line 92 and thus one section of the strip 4 of the nozzles 5.

After the information has been entered, the synchronization pulses no longer go to the re-unlocking multivibrator 91, therefore, the output signal for starting the multivibrator 90 is provided with a negative transition of such a signal. Then the multivibrator 90 applies a starting pulse through a line, 92, the duration of which is proportional to the charge accumulated in capacitor 93. This charge is obtained through a resistance 94 through a line 95. (Line 95 is connected to a switching attenuator (not shown), which

can be switched to provide voltage variation so that the duration of the starting pulse can be selected in the range from 4.5 to 12 m Ci or in the range from 4.5 to 47 ms.

The starting pulse is applied as a single signal to the input of the valve 88, which, when the turn-off relay 89 is closed, the strip 4 of the nozzles 5 will open to provide a signal

Inlet O in line .87. Because

The voltage is less than +3 V supplied by source 96, then the amplifier 81 will change the mode to generate a voltage of +2 V. Therefore

a selector signal of +2 V is applied by do lines 78 to one input of each amplifier 77 (Fig. 11). Since the other input of each amplifier 77 is fed O or +5 V,

appropriate information about the pattern stored in the shift registers, then for the amplifiers 77, the mode will be set depending on this information. For greater assurance that the nozzles 18 of the 4 nozzle strip 5 will not

controlled in accordance with the figure information, until all the shift registers of the 4-nozzles strip 5 are fully loaded, the output of the first unlocking multivibrator 91 is of such duration that after the termination of the synchronization pulses, approximately 25 microsec passes: d.p delay of unlocking the multivibrator 90.

Line 79 of the outputs of the amplifiers 77 (FIG. 11) is connected to transistor drivers in the circuit 53 of the solenoid valve. Each driver device has a solenoid valve coil in its collector circuit to turn on this valve when the corresponding information bit

equals

while the voltage on the selector line is 2 volts.

If the conveyor belt is moving relatively fast, then it is possible that the control panel, 44 (FIG. 8), requires new information about the figure L of the counting machine.

46 at a time when the dispenser 50 is applying a dye to the pile carpet in accordance with previously obtained information about the figure. This condition is known as speeding when a relatively long time for starting or operating the nozzles 5 is set. Conveyor 3 can be moved 2.5 mm to cause flow from

the electronic registration system 31 (Fig. 2) of the unlocking pulse on the control panel 44, so that new information about the pattern is required, while the multivibrator 90 For the operation of the nozzle 5 generates a working impulse from

a long period of time along line 92. -, the protection circuit against speeding 1g: b1 includes a single-stable

multivibrator 97 having an input connected to the output of the valve and an output connected via line 99 to the warning circuit 100. The valve 98 receives at the input a synchronization pulse via line 62 and a second signal at the input, which is a starting pulse from the multivibrator 90. If both, synchronization and start-up, pulse, arrive at the valve 98, then the strip 4 nozzles 5. Operation 6-day distributor receives new information. Under this condition, the valve 98 will be open to provide an output pulse, whose negative conversion will unlock the multivibrator 97.

The output signal from the multivibrator 97 will go to the warning circuit 100, which includes the first

and the second transistors IQl and 102. The transistor rccrates to power a warning device, such as a lamp 103. When the operator sees,

That lamp has 103, then it can either increase the working period

or reduce the speed of the conveyor belt. . - Pry; The% above explanation refers to the normal duty cycle. In hard work, when the line of carpet tiles is under the strip of nozzles 5, a certain equal amount of dye is applied through the holes 18, in accordance with the picture information stored in the counting machine 46. However, when designing the pattern, it may be necessary to apply different concentrations paint-on a given line of carpet tiles. For example, it may be necessary to apply on the outside of the pattern of this line a weak

its color & YOU, and on the inner parts of the picture it is necessary to apply a thicker green color. This difference in shade can be made using the split loop operation now described.

In FIG. Figure 13 shows the cycle control chain to provide both normal and split cycle operation. This goal is only required for splitter 1 shown in Fig. 8. The 3K trigger104 has its inputs 3 and K connected to one fourteenth line 71 or a counting input connected to the fourteenth of the synchronization lines 72. The individual 71.72 lines transmit eight redundant and / or synchronization bits, i.e. byte pok azanny fyg.9. Stew

trigger 104, the signal is fed to a single-stable multivibrator. 105, 1 6th sends an output pulse on line 106. Duration or

The width of the output pulse of the multi-vibrator 105 is equal to the maximum operating time of any distributor. This is achieved by charging the capacitor 107 through the resistance 108 from a switchable attenuator (not shown), and is also charged as the capacitor 93 of the multivibrator 90 (Fig. 12).

The output signal from the multivibrator 105 (Fig. 13) is fed to another single-wall multivibrator 109, which negatively transforms the signal on line 106. The output signal of the multivibrator 109 is fed to the 48 line going to the calculating machine 46 to report additional information drawing of each of the eight distributors. In response, the counting machine 46 sends a block of information about the pattern in response to either the pulse E from the registration system shown in FIG. 7 or the pulse from the multivibrator 109.

During a normal operating cycle, eight synchronized bits for each eight groups of 1568 bits have a value of how it is shown (FIG. 9). These eight bits are sent through the fourteenth line 71 to the trigger 104. Since these bits have the value O, the trigger 104 does not change its mode and does not issue the output-. the output signal for actuating the multivibrator 105. Accordingly, the multi vibrator 1 € 9 is not open and there is no need for additional information about the pattern before receiving the next pulse E from the registration system 31.

When splitting the work cycle, the type of information includes odd and even cycles, in which the odd cycle must have at least one, and preferably all eight, synchronization bits in 11 11 I

The eight synchronization bits of the even cycle are all about

During the odd or first cycle of the split cycle, the information bit M enters the 3-K inputs, and the trigger 104 is unlocked using a synchronizer, thereby triggering the trigger of the multivibrator 105. Then the multivibrator 105 generates a signal whose duration is equal to the maximum time p & bots of any distributor 50 which is given by the capacitor 107. This signal undergoes a negative transformation when the multivibrator 109 is unlocked. Then the unlocking pulse is provided for the required figure information for even cycle vsehraspredolyteley 50.

Then, the counting machine 46 sends an additional pattern information block with synchronization bits, which are all. Oh, so there is no additional demand for information about the pattern until the registration system 31 sends the next pulse E. If the working cycle is odd, the cycle of information about the pattern carries information about applying a certain amount of dye to the carpet tile. During the even cycle, the pattern information carries information about applying additional dye to the required areas of this line of carpet tile, thereby increasing the concentration in these areas and providing different shades of a certain color. With a split duty cycle, an even cycle information may not be required, since any of the valves 50 operates in accordance with the odd cycle information stored in the shift registers. In other words, the even cycle information must be entered into registers before the odd cycle information is used to apply the required amount of dye. To prevent this, the output pulse from the multivibrator 105 has a width equal to the maximum working time of any distributor and the advantage arising from this fact is that it creates a drooping pr, approximately 1 ms before entering information into the eight distributors 50. Moreover, the information decomposed by the control panel 44 is first (entered into the distributor 1 and takes about 1 ms to do so. Then the decomposed information is entered into the distributor 2 and this takes another millisecond, etc., t. i.e., an approximate delay in 8. ms is between the inflator time 1 and 8. For example, if the maximum operating time of the splitter 50 is 10 ms and it is set for the distributor # 3, then no even cycle information will be perceived by distributor # 3, before it finishes working. When distributor # 1 is an odd-cycle formation, the multivibrator 105 will send an output pulse having a duration of 10 ms. After 2 ms of the work of the distributor C, the distribution (Fig. 8) will be loaded with information and will begin operation within 10 ms. After six elapsed milliseconds, the And distributor may be ready to receive information of the even cycle (if its working time is only 8 ms. However, the remaining 105 duration of the pulse 105 oracle will still be 2 ms and 4 ms of the distributor 3. Then, after a 2 msec interval, the multivibrator 108 will open and an even cycle information will be required, and the distributor 3 will have only 2 msec of working time. Hci will end, after another 2 msec the even cycle information will be entered into reg distributor # 3 immediately after the end of work on the odd-cycle information. With such a split working cycle and in view of the latency time when the pattern information is stored in the registers of eight distributors 50, even-cycle information may be required despite the fact that the last distributors work according to the information of an odd cycle. This makes it possible to obtain the desired pattern with a very high degree of accuracy, since the conveyor will move almost an infinitely small distance before n additional dye to increase the concentration of certain areas along a predetermined line of a carpet tile. The continuously operating strips of the 4 nozzles 5 (Fig. 2) can be separated from each other, for example, by 25 cm. Therefore, information about the pattern on the magnetic tape in the counting machine 46 can be separated from each other by a distance equal to the time it takes for a carpet tile line to move 25 cm from one distributor lane to another. Thus, if the nozzle strip # 1 causes a red dye, and the nozzle strip # 2 is a green dye and two adjacent areas on the carpet tile line get red and green dye , Respectively, then the information stored in a. calculating machine 46 should be placed as follows, so that these areas were under the nozzle strip # 1. The red dye will be applied to one area, and after moving the tile line by 25 cm, the green dye is applied to another area. The invention can be used to apply any desired pattern to a fabric. It is particularly suitable for applying irregular geometric patterns, such as oriental or floral patterns, which require the creation of separate colored areas of small irregular sizes. . Textile material can be a long pile of fluffy carpet material that can be cut into many individual rugs. Although the invention has been described with reference (Oh, the particular difficulties arising from the picturesque dyeing of pile fabrics and especially carpets, it is obvious that the dyeing unit can be used to satisfactorily paint other porous materials, such as sheets of main yarn, woven, knitted and nonwoven fabrics, etc.

With a split work cycle or with the continuation of it, described with reference to Fig. 6, a plurality of analog synchronizers can be used, they are included in the operation one per. others to establish working times for two or more segments into which the period T is divided.
