Description

The invention relates to a method for dyeing a porous textile material, in particular a pile or pile fabric or carpet in a pattern in which the fabric is in at least one row extending transversely to the movement of the fabric of paint nozzles is moved past and one from each paint nozzle continuously emerging jet of dye with dye liquid according to the movement of the fabric and the pattern to be formed directed onto the fabric and directed away from the fabric.

The invention further relates to a device for carrying out the method with a conveyor for moving the substance, at least one row arranged transversely to the conveyor of paint nozzles, a device for pumping the dye liquid in continuous jets of paint from the paint nozzles and deflection devices individually assigned to each paint nozzle, the

from a pulse device that responds to the movement of the conveyor, are controlled by a pattern controller and the paint jets are normally transported by the conveyor Distract fabric.

Porous textiles, such as pile and pile fabrics or poly and pile carpets or tiles have long been colored with natural and synthetic colors; in particular is It has long been known to use colored fabrics Color patterns. In the past, stamps with punch holes that corresponded to the pattern were used to form the pattern have shaped protrusions covered with paint and pressed onto the fabric. The speed of production of the pattern could then be increased by developing it can be increased by printing presses. In such roller printing machines the moving fabric comes in repeated contact with engraved metal rollers, each of which printed a different color on the fabric to form the desired pattern.

Recently it has been proposed to dye or print porous textile fabrics with patterns by following a predetermined program of staining solution consisting of color rays on the surface of the under openings from which the color rays emerge, be directed along moving fabric. Suggestions for such methods and devices for their implementation are described, for example, in US Pat. Nos. 2,804,764 and 3,502,044 and GB-PS 978,452. In general, such an apparatus comprises a plurality of nozzle bars extending along the direction of movement of the fabric are spaced from one another and each have a row of to the

Have fabric-directed nozzles. Each such nozzle can be electrically, pneumatically or mechanically controlled dye liquid spray onto the moving substance, the sequence of spraying using programmable control devices, to which the required data is entered, for example via punched tape, magnetic tapes and the like, is controlled.

In DT-ES 1 460 349 there is a sample injection printing device described, in which from the nozzles continuously color jets emerge with coloring solution, which can be deflected by means of a deflection device, for example a compressed air nozzle so that they only get onto the fabric temporarily. The deflected ink jet is directed into a collecting trough where the staining solution is returned to a storage container. The deflection of the individual color rays or the impact the compressed air nozzles with compressed air is controlled by a programmable control device.

In practice, there are numerous problems associated with spray printing patterns onto porous fabrics:

For the formation of fine or complex patterns there is both a small distance between adjacent ones Nozzles as well as a very precise control of the points at which the ink jets reach the fabric is required. When injection printing highly porous fabrics, such as Pile and pile carpets are, there is also a precise control of the amount of dye solution that gets onto the fabric required so that the dye solution penetrates into the depth of the fabric in a defined manner and no undesirable Coloring intensity fluctuations occur. Further it is important to avoid that the dye solution, which reaches precisely defined surface elements of the fabric, does not diffuses into neighboring surface elements.

The invention has the purpose of providing colored carpets in one of the carpets made with different colored fibers or yarns to create a comparable variety of patterns and fineness, using single-colored fibers or yarns for their manufacture can be.

The invention is based on the object of developing a method of the type described at the beginning in such a way that patterns can be formed in a fineness as can be achieved by conventional manufacturing processes of the textile fabrics with use can be achieved by yarns in different colors,

or, for example, as with conventional Axminster / Wiltron weaving processes.

This object is achieved according to the invention in that the selective deflection of the color rays during repetitive Cycles of data blocks with pattern data is controlled, each cycle by moving the fabric by a predetermined amount Track is triggered, all color rays within each cycle hit the fabric for a predetermined period of time can be directed and are actually directed to the fabric according to the pattern data during these time periods ^ and a rest period is maintained within each cycle during which all paint rays are deflected away from the fabric.

With this method, a certain area of the fabric can be applied by repeated, intermittent application of dye solution to be colored. For example, if there is a continuous line of color along the fabric under a certain ray of color is to be formed, the jet of paint does not hit the fabric along the entire length of the line, but is Applied in individual amounts by periodically deflecting the jet of paint according to the movement of the material will. This enables very precise control of the amount of dye, those on the fabric

applied and minimizes the possibility of that the dye gets into the wrong place due to incorrect movement of the material during the application of dye. Furthermore, the invention has the advantage that on a "continuous" colored line that in conventional Coloring process observed increase in intensity from the beginning and end of the line towards the middle largely suppressed will.

The rest time is advantageously at the end of each cycle.

One or more color beams can occur within one or more predetermined time periods during one or more predetermined time segments are directed to the fabric. This ensures that there are also shades of color or mixed colors can be formed by multiple coloring of a surface element.

The color rays ground from one in each time segment Data block controlled from a data source determining the pattern and the data block for the first time segment is retrieved from the data source upon initiation of the cycle and each data block with the exception of the last data block of a cycle controls the fetching of the data block for the following one Time segment.

The rest time is advantageously at least as long as the recovery time of the color beam deflection device. In order to it is achieved that after a new cycle has been initiated, all color deflection devices for converting the new data block to be ready.

- 6 509828/0781

45 453

The predetermined time periods are advantageously approximately the same length in each cycle.

The duration of the time period is adjustable.

The predetermined distances that determine the initiation of the cycles are essentially of the same length. This achieves that changes in speed in the movement of the substance largely.without influence on the amount of dye remain, which is applied to a surface element of the fabric.

In a further development of the method, several rows of paint nozzles are used, which are separated from each other in the direction of movement of the fabric are removed and in which the deflection of the color beams of each row is controlled in the way they are for each cycle is defined.

Advantageously, the color rays become pattern data in each time period or each time segment thereof from a block which are made available in serial form from the data source, with the Bits belonging to color nozzles are combined into groups which are distributed to registers which correspond to the rows and Have stages that correspond to the paint spray openings of the row, with the bit reaching each stage deciding whether the paint jet from the associated paint nozzle hits the fabric or not.

Each color beam in each time period or each time segment of the time period is controlled by an associated data bit and a logical product of this data bit and one the duration of the time period or the time segment of the period determining time pulse is formed so that the color

45 453 - 7-

ray can only reach the substance at one value of the data bit and then only during the time pulse.

The color jets from the color nozzles are continuously released under pressure.

Advantageously, the predetermined route is preselected in such a way that it has the dimensions of a mesh or with the distance between adjacent poles of the fabric in the direction of movement of the fabric coincides.

The time period is chosen so that enough dye solution reaches one stitch or one pile of the fabric essentially des.en full depth to color.

The number of color rays in a row is essentially equal to the number of meshes or poles of the fabric across the direction of movement.

In a preferred embodiment of the method, the porous material is a sheet of pile or pile carpet several individual carpets can be cut, with the special pattern corresponding to the individual carpet Pattern is, and the entire pattern is applied to successive areas of the sheet of pile or pile carpet, while this is constantly under the paint spray openings and then through a sequence of finishing Processes in motion.

A device for carrying out the described method is characterized according to the invention by the pulse device that generates trigger pulses, the successive, mark cycles of operation corresponding to movement of the conveyor a distance, and the pattern control device, controls the deflectors according to stored data to allow selected color beams during a or multiple time segments arrive on the fabric within each cycle. and a timer device that the

5 0 3828/0781

45 453

The duration of each time segment is determined to be shorter than the duration of a cycle and independent of any Changes in the duration of a cycle is fixed.

With this device thus get within each cycle, i.e. the movement of the fabric by a predetermined one Route, individual color beams according to the pattern data for a given period of time Material.

Advantageously, the device further has a data source with data blocks, each of which is assigned belongs to a: time segment, a storage device in the pattern controller for storing a block of data and a 'responsive to each trigger pulse emitted by the pulse device. Device that causes a new data block is transferred from the data source to the storage device.

Furthermore, the pattern control device advantageously has a device that acts on selected data blocks is responsive to cause another block of data from the data source to be placed in the storage device is transmitted to create a succession of two or more time segments within a cycle, where the period of time required by the succession of time segments is less than the duration of a cycle is. With this design it is achieved in a simple manner that shades of color can also be formed.

The pattern control device has circuitry that enables the transfer of n data to any deflection device prevented as long as the deflection device is controlled and enables the associated color beam hits the fabric.

A further development of the device is characterized in that the pattern control device for each paint nozzle stores a data bit, the value of which decides whether the associated color beam remains deflected or is open the fabric can hit that the timer device generates a time pulse which determines the duration of a time segment / and that a device for forming logical Products between the timing pulses and the data bits are provided to generate signals that the deflection devices individually controls, so that each color beam only for one value of the associated data bit and then only can get on the fabric during the time pulse.

Fig. 1 illustrates a pattern injection printing apparatus for forming of colored patterns on porous textile fabrics, in particular on pile and pile fabrics and pile and pile carpets and tiles. The "device is here based on the printing of carpet tiles 11 stored on a storage table 10. Instead of those stored on the storage table 10 Carpet tiles 11 could just as well be used a supply roll with a continuous carpet web that goes through the entire device is moved. The carpet tiles 11 are by hand or by a suitable, not shown mechanical device placed on the lower end of an inclined conveyor 12 of a paint application area 14, in which the carpet tiles using the programmed actuation a plurality of nozzle bars 16 are spray-printed. The nozzle bars preferably do not spray

divergent rays of color from dye liquid onto the surfaces of the carpet tiles as they move through the Move paint application area 14 through. The carpet tiles that are dyed in a pattern and applied by the dye are calibrated 14 are transported by further conveyors 18, 20, which are driven by motors 22, 24- into a steam chamber 26, in which they are used to fix the ones on them Dyes are exposed to a steam atmosphere Carpet tiles 11 leaving steam chamber 26 are transported through a water washing device 28 to remove excess, unfixed dye from the tiles to remove, and then pass through a hot air dryer 30 on a collecting table 32, on which they are by hand or by another suitable device, not shown, can be stacked for subsequent further use.

Fig. 2 shows an enlarged plan view of the paint application area 14 according to FIG. 1 and shows the endless conveyor 12, the chains and drive wheels (not shown), which are mounted on rotatable shafts 34, 36, the shaft 36 being driven by a motor 38. To the Spray printing of carpet tiles of rectangular or square shape is the surface of the endless conveyor 12 with several separating rods or spacers 40 are provided, which the tiles in precise spatial alignment with one another align with the conveyor. During the movement of the conveyor, the carpet tiles arrive essentially in sequence identical nozzle bars 16 past, five of which 42, 44, 46, 48, 50 are shown schematically and each other extend along the path of movement of the endless conveyor over its full width.

As can best be seen from FIGS. 4 and 4, the only represent a single nozzle bar 42, each nozzle

- 13 - 45 453

bar a large number of ^ individual paint nozzles 52, the are arranged along the nozzle bar in such a way that they do not diverge or focus color jets on the surface the carpet tiles passing by. Each nozzle bar has a dye solution supply line 54 (Fig. 5), which is connected to the paint nozzles 52 and from its own storage tank 56 via a pump 58 is supplied with coloring liquid. In operation, dye liquid is continuously in non-divergent color rays sprayed from the paint nozzles 52 onto the fabric to be printed.

In addition to and at right angles to each nozzle 52, an outlet 61 of an air supply line 62 (FIG. 5) is arranged according to FIG. 5. A separate solenoid valve 64 is arranged in each air supply line 62. The solenoid valves are operated by a compressor 66 supplied with air. In FIGS. 2 and 3, the solenoid valves for each nozzle bar are with a single symbol 64 shown. However, this is to be understood in such a way that each nozzle bar has its own for each individual color nozzle Solenoid valve with an associated air supply line is provided so that the individual color jets are controlled individually can be. The solenoid valves are controlled by a pattern controller 68 such that normally Air jets hit against the continuously flowing color jets and the color jets into a collecting or collecting trough 95 lead, from which the dye solution is returned to the storage tank 56 via a line 95a.

The pattern control device 68 for actuating the solenoid valves comprises a digital switching device with magnetic tape transport to store the pattern information. The magnetic tape can be used to print repetitive patterns be provided with a repeating sequence of information,

- 14 509828/0781

- 14 - 45 453

which is transmitted to the solenoid valves "until a certain Number of carpet tiles is spray-printed. In the present In this case, a series of ten tiles (5 pairs) can be spaced apart on the conveyor belt and the pattern controller is initially actuated when the leading edge of the first tile comes under the first nozzle bar 42 is located. The information from the magnetic tape and the switching device is then used to turn it on and off the solenoid valves are used to dye the carpet tiles sequentially in the desired pattern while they move along below the nozzle bars.

In operation of the device, if the pattern control device 68 does not provide any information for the solenoid valves of the nozzle bar, constantly emitting dye solution under pressure each paint nozzle 52 is sprayed onto the fabric to be printed. Each solenoid valve is normally open so that constantly hit air jets against the continuously flowing color jets and at the same time bring them into the collecting troughs direct the nozzle bar for reuse. As soon as the first tile in the row of tiles to be printed is the first nozzle bar happens and the pattern control device is operated, a certain number of the normally open Solenoid valves closed so that the associated color rays are not deflected, but directly onto the fabric meet. In this way, by turning the solenoid valves on and off in a desired sequence, a printed Patterns are formed on the fabric as the fabric moves.

As the injection pressure inking machine continues to be used, the speed of the conveyor that carries the Textile material is transported, something can change or its position can otherwise change, which causes could that the color pattern to be formed on the tiles

509828/0781

is incorrectly aligned with the material to be printed on. Therefore, means are provided with which the location of the conveyor and starting the triggering of the signals from the pattern controller 68 for the solenoid valves with each other can be correlated. As shown schematically in FIGS. 2 and 4, these means have a synchronizing switch 70, a transducer 72 and an electronic pulse device 74. The synchronization switch 70 comes with periodically a mechanical finger 76 attached to the edge of the conveyor 12, while the transducer 72 engages with it the shaft 36 works together to convert the mechanical movement of the conveyor 12 into electrical line impulses, which are nominally generated every millimeter.

As can best be seen from FIG. 2, the transducer 72 can operate mechanically, optically or electromagnetically mechanically connected to the shaft 36 via gears 78, a desired number for every centimeter of advancement of the conveyor of impulses to be emitted. In the example described, the gears are chosen so that every 1 cm movement of the conveyor 10 distance impulses are emitted.

From the signal transmitter 72 route pulses are sent to the pulse device, from where trigger signals are then sent to the pattern control device 68. The pulses are used to fire the individual colored jets of the nozzle bar are only sent to the fabric when the fabric has moved by a predetermined, has moved the selected distance relative to the position of the nozzle bar. In a typical example, if you have a pile carpet to be colored with a pattern with a pole row spacing of 2.5 mm in the transverse and longitudinal direction, the paint nozzles of the nozzle bar a distance of 2.5 mm, measured from the center. The trigger signal from the pulse device, which activate the pattern controller would be set to produce four trigger signals for every inch of movement of the conveyor.

5098 28/078 1 - 16

The pattern control device has means with which the fabric during a time interval that of movement of the conveyor by 2.5 mm, can be exposed to color jets for certain periods of time. Like on As best seen in the timing plot of Fig. 6, after receiving a trigger signal E from the pulse device 74- has received into a state offset to send control signals to close certain air valves and the corresponding color beams get on the carpet. The length of time an air valve remains closed (and therefore no diverting air on the ink jet) -can within a period of time by suitable means, such as a analog or digital timer.

The duration of the active time period D, in which certain valves can be operated, is at the beginning of the operation and is the same in every time interval I, even if the time intervals I can change. When choosing a period of time during which the pattern controller can send control signals to the valves of each nozzle bar, the longest selectable time period is shorter than the shortest time interval I that is expected to the extent that which leaves a quiescent time Q during each interval, the quiescent time Q being long enough for valve switching times faulty electronic timers and changes in the speed of the conveyor are taken into account.

For example, the conveyor and the fabric with move at such a rate that triggers nominally every 82 milliseconds to the pattern controller be sent. The specified time period T within this interval, in the dye solution on the fabric surface can be applied, is set to 25 milliseconds, with the actual application times within

509828/0781

- 17 - 4-5 4-53

programmed in an on-off cycle operation halfway through this period will. The time period T can be divided into a number of time segments C, for example 31? be parted, and each air valve can be controlled in such a way that for a certain number of such time segments C, which forms an on-time of the operation, stay closed. The remaining segments where the valve is open to deflect the paint jet should constitute the off-time of the operation within the on-off time period T. This way of working is particularly advantageous if "in situ" mixing of the staining solutions from different nozzle bars is desired. For example, if two nozzle bars contain the primary colors blue and yellow, different shades of green can be achieved by adding sequentially staining solution is applied to the same stain of the carpet, with some staining solution from a nozzle bar the blue ink jet and some staining solution from one other nozzle bar contributes the yellow paint jet.

If "in situ" mixing is not used in staining, but is colored by the fact that desired coloring solutions on selected areas from only one nozzle bar, the one the desired color can be applied, the selected, to be operated air valves remain closed during the entire time period T. The length of the time period would at the beginning of the dyeing process according to the properties of the fabric, the viscosity and the flow rate of the dye jets, etc. adjusted to ensure that the amount of dye solution applied to the fabric sufficient to cover a given pole or poles to their base without penetrating into adjacent surfaces.

The respective size and spacing of the paint nozzles _f

the viscosity of the dye solutions used, the amount applied to a particular core of the fabric Staining solutions, etc. depend on the respective properties

- 18 - 4-5 453

of the fabric to be dyed. Experience in spray printing of patterns on pile or pile carpets shows that for

Carpets with a density of about 500 to 1500 g / m and a pile height of about 3.2 to 3.8 mm, a distance between the paint nozzles of about 2.5 mm and an opening size of about 0.25 to 0.65 mm (with a ratio of nozzle length to diameter of 5 x 13) gives good results in dyeing. In addition, viscosities of the dye solutions between about 50 and 1,000 have been found to be very effective for dyeing carpets. The prints used by the

Color rays can vary from about 0.56 to 1.05 kp / cm.

The exact intervals between trigger pulses E, the time periods T, during which the signals from the pattern controller are sent to the valves and the rest times Q within an actuation cycle depend on many influencing variables, for example the speed of the fabric, the density and the type of pile yarns used in a carpet, the desired distance between the smallest coloring solutions applied to a pole, the viscosity and the pressure of the application, the minimum valve switching times etc. With the device described, the fabric was 9 m de minute moved further to apply a 330% absorption of dye liquid, based on the weight of the pile yarns, the minimum distance between the applied dye liquids being 2.5 mm along the fabric; the time between successive trigger pulses E was 16.5 milliseconds. The time period T during which actuation signals could be sent was 15 milliseconds, so that a rest time Q of 1.5 milliseconds remained. This idle time is sufficient for a valve switching time of 1.5 milliseconds (the switching time of the described solenoid valves) if the valves in the entire on-off cycle time period T in the off position remains. The rest time is preferably Q

at least 5% cLeJr time period I between successive ones Trigger pulses. ,

As described, the fabric moves along an inclined path during exposure to the color jets. The angle of inclination used is chosen so that a compromise between the opposing influences of the Gravity on the direction of the dye jet and the running or distribution of the dye solution after application to the fabric surface is achieved, with enough space remaining between the nozzle bar and the fabric surface for drainage to allow the dyeing liquid from the collecting trough due to gravity and a possible dripping of the dyeing solution from the nozzle bar onto the fabric or carpet. Angles between 15 and 50 ° to the horizontal can be used be, an angle of about 25 ° is particularly advantageous.

Fig. 7 shows the pulse device 74 ·. When the synchronizer switch 70 from finger 76 at the moment in which the The first carpet tile on the conveyor reaches the nozzle bar 4-2, when finger 76 is actuated, it sets flip-flops 65 »67 and counter parts from counters / comparators 71, 73, 75 back. Each pulse emitted by the transducer 72 sets the flip-flop 65 so that a clock 6Sa begins to oscillate. Impulses from the clock 69 to the counters / comparators 71 and 73 The comparator part of the counter / comparator 71 is manually open a number set (on a manually adjustable digital indicator 71a shown as 10), which allows this number of pulses coming from the clock 69a to be entered into the counter / Komperato- ' ren 71 and 72 before the counter part 71 and the Flip-Flop 65 can be reset and in this way the oscillation of clock 69 is stopped.

The comparator part of the counter / comparator 73 is set to one Number (on a manually adjustable digital indicator 73a

shown as 25), this number of clock pulses allows to get into the counter part of the counter / comparator 73 before the counter / comparator 73 emits a pulse will. This pulse goes into counter / comparator 75, and back to reset counter / comparator 73, and as Trigger pulse to pattern controller 68. Upon receipt of a trigger pulse from counter / comparator 73, the sends Pattern controller 68 one of its stored pattern signals to momentarily switch off one or more solenoid valves, whereby the corresponding color rays hit the carpet tiles. When the counter / comparator 75 has a certain Number of pulses from the counter / comparator 73 (shown on a manually adjustable digital display 75a than 980), it sends a signal to the flip-flop 67 to set it and to block an AND gate .77, thereby preventing further such signals or pulses from being sent from counter / comparator 73 to the pattern controller 68 are transferred. This setting on the indicator 75a is according to the number of tiles or the length of the textile material to be printed in an operational sequence of the operation of the pattern control device is selected.

The number of distance pulses emitted per centimeter by the transducer 72 is multiplied by the counter / comparator 71 and then divided by the counter / comparator 73 by, in the example described, the pulse rate (per cm) by a factor 10/25 to decrease. This ratio can be adjusted by adjusting the indicators 71a and 73a so that the Pattern fits exactly into the tiles. ' In this way, factors such as wear of the conveyor 12, for example, are compensated.

Fig. 8 is a block diagram of the pattern controller 68. A main control panel 80 has one attached to a computer 69 connected input 84 and a line 86 coming from the electronic pulse device and supplied via a

An output is a line 85 to the computer 69. The control panel 80 has 8 additional outputs which are connected to 8 distributors 82 via conductors 81. 8 nozzle bars, such as the nozzle bar 42, are connected via lines 96 to the corresponding manifolds, with each nozzle bar has a nozzle bar connection panel 98, which with a Conductor 102 is connected to a solenoid valve card 100.

Each of the 8 nozzle bars has 1560 nozzles or exit openings which are controlled by 560 solenoid valves. The pattern word or pattern data output by the computer 69 comprise blocks of 8 × 1568 bits and time pulses or data. Clock pulses.

When the conveyor 12 has moved 2.5 mm, the electronic pulse device 74 sends an off pulse to the control panel 80, which then requests a block of sample data from the computer 69 via line Q ^. The computer 69 then supplies at its output a serial bit stream with pattern data, which include time pulses, which is fed to the control panel 80 via the line 84.

Figure 9 shows the format of a serial word from computer 69 for normal cycling. The control panel 80 demultiplexes the word and the time pulses into 8 groups of 1568 bits each, each group being sent to one of the 8 distributors 82 is transmitted. The first 1560 bits of each group contain pattern information for each of the 1560 nozzles in a nozzle bar, while the last 8 bits or the byte are not used in normal cycle operation.

Fig. 10 schematically shows the circuitry of the control board 80 for demultiplexing the pattern data and clock pulses. The control panel 80 includes a pair of lines 84a and 84b which receive pattern data and clock pulses from the computer 69, respectively. The time pulses are fed to a red decoder 118.

The sample word is fed to a second decoder 138.

Each decoder 118, 138 receives from an address counter
140 via lines 142 or 144 address information and forwards the received bits via lines 146, 148 according to the address information to the 8 distributors. The address counter
140, after receiving a predetermined number of timing pulses from control panel 80, counts up by one to identify one of lines 146, 148 and thereby apply a number of data bits and clock pulses to those lines. In order to advance the address counter 140, the line 84b is additionally connected to a monostable multivibrator 152 whose positive output pulse is connected to the counter / comparator

For this purpose, the line 84b is additionally connected to a retriggerable multivibrator 182 via a line 183, the output of which is connected to a main back part input of the counter 140. The multivibrator 182 retriggers continuously - and thus does not generate a negative output (reset) signal until no clock pulses are received at its input. Furthermore, the counter 160 is reset after it
has reached a fixed count. The output of the
Gate 176 is fed to a monostable multivibrator 188.
The output of the monostable multivibrator 188 is fed to a NOR gate 192, which as a second input via a line 184 is the output of the retriggerable multivibrator

182 receives. The output of gate 192 is with the main back The input of the counter 160 is connected.

The decoder 138 directs the received data to the various Outputs 148 for transmission to the appropriate distributors 82. As can be seen from the format of the word of Fig. 9, become the first 1568 bits of a serial bit stream forwarded to the first distributor, the second 1568 bits the second distributor, etc. To this end, the counter 140 is incremented by one every 1568 time bits. The decoder similarly directs the clock pulses to lines 146 which are individually associated with the nozzle bars.

When the pattern data and clock pulses are demultiplexed into 8 groups of 1568 bits, the function of each distributor lies 82 is to decode each received group into 13 subsets of 120 bits each, each one width of 120 χ 2.5 mm across the width of the conveyor 12. For this purpose, the same demultiplexing technique is used as in FIG. 10, which is therefore not shown in more detail. Short has each of two decoders (one for data and one for clock pulses) 14 output lines 224, 226 (Figures 11 and 13) · The first 120 bits are fed to the first output lines, the second 120 bits to the second output lines and so on. the Last 8 bits of the data and clock pulses of group 1568 bits received from a distributor become the 14th output lines 224, 226 of the two decoders switched on.

The pattern data and TaKtulse for a nozzle bar are now grouped into 13 groups of 120 bits per group. The distributor 82 stores these bits in a series of 13 groups of shift registers. Each register in a group can have 4 Store bits of pattern data; the data of each line 224 from the data decoder (not shown, but briefly described)

- 24 08: 328/078 1

- 24 - 45 453

are then shifted into 30 registers, which together make up 120 bits form comprehensive shift register. In Fig. 11, only two of the registers 288, 290 are shown. The first shift register 288 receives pattern data over line 224, with line 224 passing through line 226 and inverter 292 received clock pulses is clocked. Each of the 30 shift registers has 4 output lines 296 for each of the 4 stored Bits connected as an input to 4 associated operational differential amplifiers 298. The fourth Stage of the first shift register 288 is connected to the input of the second shift register, etc., so that the 120 Bits are shifted into the 30 registers. The second entrance each operational amplifier 298 is connected to a signal line 302 with a voltage which is used to via an output line 304 of the amplifier the various Solenoid valves have a predetermined and adjustable "firing time" according to the pattern information stored in the registers to operate.

The 4 bits stored in the shift register 288 represent a logical zero or a logical one, for example and can correspond to 0 volts or 5 volts. The output voltage each operational amplifier 298 depends on whether the voltage on line 296 is greater than or less than the voltage of the signal line 302. Only when the voltage of the data bit exceeds the voltage of the signal line is the output value of an amplifier so that a solenoid valve is actuated and dye solution through an associated nozzle the carpet tile gets. Also the length of the actuation or the "fire" time during which the voltage of the signal line controls the amount of dye solution applied to the carpet tile. Furthermore, it should be during loading of the bits in the shift registers no solenoid valve is controlled by pattern data; therefore is during this charging period the voltage in the signal line is high enough to

509828/0781 ~ ²⁵ "

- 25 - Λ5 45.3 ■

prevent amplifiers 298 from changing state and operate the solenoid valves.

In Pig. 12 shows the circuit with which the voltages suitable for carrying out the two-level operations are generated on the signal line. The I ¹ Ig. FIG. 12 shows 13 identical cutoffs 306 for the solenoid valves, one for each of the 13 groups of the 120 bits stored in a distributor 82. Each switch 306 has an operational amplifier 308, the output of which is connected to a manually operated switch 310 with contacts 310a, 310b and 310c. One input of each amplifier 308 is connected to a voltage source which supplies + 3 volts and is formed by five diodes 316. The other input of each amplifier 308 is connected via a line 318 to the output of a NAND gate 320, one input of which is connected to a switch-off relay 322 for a nozzle bar and the other input of which is connected to the output of an "I" your "multivibrator 278 The output of the switch 306 is the signal line voltage on line 302 which is applied to the operational amplifiers 298 of a corresponding one of the 13 groups of 120 bits.

During charging, a retriggerable multivibrator 268 is continuously retriggered by timing pulses from line 146. Accordingly, the fire multivibrator 278 is not triggered. The NAND gate 320 therefore does not become transparent and the associated amplifiers 308 via line 318 supplied voltage is + 5 volts. Because the + 5 volts input voltage is greater than the +3 volt voltage at the other input of amplifier 308, the output voltage is this amplifier +15 volts. Accordingly, over output line 302 is fed through contacts 310a, 310c to one of the inputs of amplifiers 298 +15 volts. Because the

509 828/0781

- 26 - 45 453.

The voltage of the data bits does not exceed 5 volts Operational amplifier 298 does not change state to operate the solenoid valves while charging. Further The relatively high voltage of +15 volts in the signal line also prevents noise in the circuit causes amplifiers 298 to switch while charging. The contacts 310a and 310b of the manually operated Switch 310 can be closed to, a shift register turn off and put a portion of a nozzle bar by means of the 15 volts on a line 326 out of service.

After loading, the retriggerable multivibrator 268 no more time pulses received; this creates an output signal that the multivibrator 278 at its negative Signal transition fires. The multivibrator 278 then generates a fire pulse in the line 286, the duration of which is proportional to the charge stored in a capacitor 280 and received from a line 284 through a resistor 282 will. The line 284 is connected to a switchable amplifier (not shown) which can be switched can to generate a charging voltage such that the duration of the "fire" pulse is a preselected value within a Range from 4.5 "to 12 milliseconds or within a range from 4.5 to 47 milliseconds.

The fire pulse is fed to an input of gate 320, which is actuated when the switch-off relay 322 is closed and an output pulse of 0 volts in the line 318 generated. Because this voltage is less than the +3 volts supplied by voltage source 312, the amplifier changes 308 its state and generates + 2 volts. As a result, each of the amplifiers is connected to one input via line 302 298 (Fig. 11) is supplied with a + 2 volt signal. Because at the other input each of the amplifiers 298 is 0 or + 5 volts, according to the pattern stored in the shift registers

509828/0781 -27-

. - 27 - 45 453

data prevail, the amplifiers 298 switch their states according to these data. To further ensure that the paint nozzles 52 or-Spritzöffnun ^ n of a nozzle bar 42 cannot be controlled according to the pattern data, if not all shift registers of the associated nozzle bar are fully loaded, the output signal of the retriggerable Multivibrators 268, a duration of about 25 microseconds, after no more timing pulses are received to delay the triggering of the multivibrator 278.

The outputs 304 from amplifiers 298 (Fig. 11) are connected to transistor drives in the solenoid valve card 100 (Fig. 8), each of which is the winding of a solenoid valve has in its collector circuit to switch off this solenoid valve, when the corresponding data bit is a "one" and the voltage on the signal line is 2 volts.

If the conveyor is moving relatively quickly, the control panel 80 may receive new pattern data from the computer 69 requests, while a distributor 82 is still causing the staining solution according to the data previously requested originating pattern data is applied to the carpet tile. This condition is known as "over speeding" and can occur when a relatively long actuation or firing time is set. That is, the conveyor 12 can moved 2.5 mm further so that the recorder 74 generates a trigger pulse for the control panel 80, which then requests new pattern data, while the fire multivibrator 278 generates a fire pulse of relatively long duration via line 286. This undesirable condition can be determined by a speed shown in FIG. 12 and can can be corrected by either reducing the speed of the conveyor or reducing the activation or firing time.

5098 2 8/0781

- 28 - 45 453

The overspeed protection circuit has a monostable multivibrator 34-4, the input of which has the output of a NAND gate 346 and its output a line 350 is connected to a warning circuit 352. Gate 34-6 receives clock pulses and clock pulses on line 146 the fire pulse from the multivibrator 278 via a second input.

If the gate receives both clock pulses and fire pulses, this indicates that a nozzle bar is at the same time Time at which the distributor receives new sample data. Under this condition gate 34-6 is actuated and delivers an output pulse, the negative transition of which denotes the Multivibrator 34-4 triggers. The output signal of the multivibrator 344 is then fed to warning circuit 352, which includes first and second transistors 354 and 356. The transistor becomes conductive to operate a warning device such as lamp 358. When an operator sees that lamp 358 is on, he can reduce the firing time or the speed of the conveyor.

The above statements related to normal cycle operation. In this operation, if there is a line a carpet tile is located under a nozzle bar, a predetermined, equal amount of dye solution through the paint nozzles 52 applied in accordance with the pattern data stored in the computer. However, it can be with a sample design It may be necessary to apply different concentrations of color to a given line of carpet tile. For example the outer areas of a design on a given line may require a lighter green color, while the inner areas need a darker green. This different shading is shown in the following Reached the partial cycle operation to be described.

Fig. 13 shows the cycle control circuit for. To adjust either normal or partial cycle operation. This circuit is only required for the distributor 1 according to FIG. The J and K inputs of a J-T-K flip-flop 360 are aligned with the The fourteenth of the data lines 224 is connected and the T or trigger input is connected to the fourteenth of the clock lines 226 tied together. The special lines 224, 226 shown in FIG are shown, each transmit the 8 additional or Synchronization bits (i.e. the byte) according to Fig. 9. The The output of the flip-flop 360 becomes a monostable multivibrator 364, which generates an output pulse via line 366. The duration or width of this output pulse of the multivibrator 364 is equal to the maximum activation time of a manifold 94 and is obtained by a capacitor 368 through a resistor 370 from a switchable amplifier, not shown, in a manner similar to that the capacitor 280 of the multivibrator 278 (see Fig. 12) is charged. -. ■ ■

The output of the multivibrator 364 is fed to a further monostable multivibrator 370, which is fed by the negative Transition of the signal on line 366 is actuated. The output of the multivibrator 370 is fed to line 85 (cf. also Fig. 8), which leads to the computer to request additional sample data for each of the 8 distributors. The computer places a block of pattern data on both a pulse E from the recorder of Fig. 7 and a Pulse from multivibrator 73 available.

During normal cycle operation, the 8 sync bits for each of the 8 groups of 1568 bits are all logical Zero as shown in FIG. These 8 bits are fed to the flip-flop 360 through the fourteenth line 224. Because they are all zero, flip-flop 360 does not change

- 30 509828/0781

- 30 - 45 453

its state and there is no output signal that the Multivibrator 364 activated. The multivibrator becomes accordingly 370 is not triggered and no request for further pattern data is supplied until the next pulse E from Register device 74- appears.

In partial cycle operation, the data format contains odd and even cycles, in which at least one and preferably all 8 synchronization bits of the odd cycle represent a logical one. The 8 synchronization bits of the even Cycle are zero.

During the odd or first cycle of the partial cycle, a one and the flip-flop appear at the J-K terminals is triggered at the D-terminal by the clock pulse, whereby the Flip-flop triggers the multivibrator 364. The multivibrator 364 then generates a signal, the duration of which is equal to the maximum activation time of a distributor 82, as reported by Capacitor 368 is given. At its negative transition, this signal triggers the multivibrator 370, which triggers a trip Pulse to request pattern data for the even cycle for all manifolds 82 is generated.

The computer 69 then provides an additional block of pattern data, the sync bits of which are all zero, that no further request for pattern data is made until

The registration device 7 ^ triggers another pulse E generated.

In partial cycle operation, the odd cycle contains from Pattern data Information with which a predetermined amount of dye solution is applied to a line of a carpet tile will. During the even cycle, the pattern data contain information to make additional staining solution necessary To apply areas of such a line of a carpet tile, whereby the concentration in these areas is increased and

509828/0781 -31-

- 31 - 45 453

different shades of a special color arise. . '

In partial cycle operation, the even cycle data should cannot be requested while a distributor 82 is still available in accordance with the data stored in the shift registers of the odd cycle fires. Otherwise, cycle pattern data has just become pushed into the register before the data of the odd cycle to apply the required amount of Staining solution can be used. To prevent this, the output pulse of the multivibrator 364 has a width that is the same is the maximum activation time of any distributor, taking advantage of the fact that when loading of the data in which there is a delay of about 1 millisecond in the 8 splitters 82.

The demultiplexed from the control panel 80 is somewhat more precise Information first loaded into 'the distributor 1. this takes about 1 millisecond. Then the demultiplexed Data loaded into distributor 2, which takes another millisecond. This continues, so that a total of about 8 There is a millisecond delay between loading distribution lists 1 and 8. For example, if the maximum actuation time of a manifold 82 is 10 milliseconds and for the Distributor 3 is set, then no data belonging to the even cycle are received from this distributor 3 before he's finished firing. When the distributor 1 receives the odd cycle data, the multivibrator generates 364 an output pulse with a duration of 10 milliseconds. When the dispatcher 1 fires for 2 milliseconds, the dispatcher will 3 and starts firing for 10 milliseconds. After 6 more milliseconds, the distributor 1 can straighten out for charging Cycle data (if its activation time is only 8 milliseconds) ready; However, there are still 2 milli-

- 32 509828/0781

- 32 - 45

Seconds pulse duration from the multivibrator 364- (and 4-milliseconds Firing time in the distributor 3). To. The multivibrator 370 will then be triggered for 2 more milliseconds and it will be straight Cycle data requested, whereby the distributor 3 only left a 2 millisecond firing time ". Finally, after 2 more milliseconds just shifted cycle data into the register of distributor 3, especially when it is firing the has finished odd cycle data. With this partial cycle operation and with consideration of the time delay when saving of pattern data in the registers of the 8 distributors 82, cycle data can be requested while the latter Distributor still firing the odd cycle data. This makes possible, that the desired pattern is resolved very precisely because the conveyor moves only a very small distance before further staining solution is applied to the concentration along certain areas of a given line to increase on the carpet tile.

The nozzle bars 4-2 to 50 are constantly in operation and can, for example, be 25 cm apart. As a result, the pattern data in computer 69 must be on the magnetic tape a distance equal to the time it takes for a carpet tile to move 10 inches from one nozzle bar to the next. Therefore, if the nozzle bar Λ applies red coloring solution and the nozzle bar 2 applies green coloring solution and two adjacent areas of a line are to receive red and green coloring solution, the data stored in the computer are so removed that if these areas are under the nozzle bar 1, red coloring solution is applied to one area and when the line of the tile moves 25 cm further green dye solution is applied to the other areas.

The invention can be used to apply any desired pattern to a fabric and is particularly useful for applying non-geometric patterns, for example oriental or floral pattern suitable for the very detailed colored areas with small irregular ones Dimensions require.

The textile material can also be a strip of pile or pile carpet from which several individual carpets or bridges are cut. The pattern can then be a single one Carpet-like pattern that is applied to subsequent lengths of the web as it extends moved continuously under the paint nozzles.

The invention can also be used for dyeing other porous textile fabrics, for example chained fabrics, woven, knitted or knitted and non-woven fabrics, etc. can be used.

The use of an analog timer to control the duration of the fire was explained with reference to FIG. In partial cycle operation or its further expansion, as explained with reference to FIG. 6, several analog timers can be used, which are switched into operation sequentially in order to set different firing times for the two or more time segments, into which the time period T is divided.
