Description

[Detailed description of the invention]

The present invention relates to a method for applying dyes or other liquids to moving textile materials, and more particularly to imprinting various patterns on the material and eliminating unimprinted spaces between different patterns on the material. Regarding the method for. The invention also relates to products having a certain number of different patterns. Textile fibers and textile materials have long been colored with natural and synthetic dyes, and in particular are imprinted and patterned by applying colored decorations to the surface of the material with limited repeating shapes and colors. . Coloring of such woven fabrics is carried out in various ways. Early forms of printing used circular blocks filled with colored paste and pressed onto cloth. Subsequently, the speed of printing was increased with the development of roll printing, a technique in which a moving fabric is brought into contact with successive engraved metal rolls, each containing a different dye, to form the desired pattern. The fabric is also printed by sequential contact with screens, each having a pattern of pores and carrying dye of a particular color. One drawback of conventional printing methods by machines using rolls or screens is that printing short lengths of one pattern is not economically viable. The time and expense required to assemble and operate a machine with rolls or screens per pattern requires that a certain minimum number of this one pattern be printed for the process to be profitable. If a consumer places an order below this minimum number,
Either they have to decline the order, or they have to create a facility to store the patterned fabric they produce as inventory. Similarly, machines using rolls and screens have increased printing speeds, but still require considerable time to assemble and disassemble such machines. Once a machine is assembled to print repeats of one pattern, it is difficult to rapidly change over to a new pattern. Thus, for example, if a customer's urgent order for printing short lengths of various patterns has to be fulfilled, this cannot be accomplished within the required period of time. The earlier application, US Patent Application No. 683,224 (US Pat. No. 4,033,154) filed on May 4, 1976, describes a woven fabric printing apparatus. This equipment includes an electronic control unit and is used with a jet printing machine having a series of gun bars, each gun bar having a number of dye injection holes extending across the width of the endless conveyor. . The gun bars are spaced apart along the conveyor and the textile material is conveyed by the conveyor and as it passes through each gun bar, dye is applied thereto to form the pattern. For each periodic train request, which is a request for data for all gun bars used to print a pattern, the electronic controller receives pattern data for all gun bars from the computer. The controller analyzes the data and sends it to each gun bar to control its multiple injection holes. Thus, each gun
The bar applies dye to different rows of fabric according to the pattern information it receives, and once a row of fabric has passed under all gun bars, the desired color is stamped for that row. It is stamped. The device described in this earlier application has been in use for more than a year for producing and selling patterned woven fabrics. In this use, the device prints a predetermined number of repeats of the desired pattern. Although not described in the prior application, to complete the last row of the last repeat of the pattern, this last row first passes through gun bar #1, which applies the color defined by the pattern data to the row. It is taken as a section along the line.
When this last row is then moved towards gun bar #2, gun bar #1 does not make any impressions since it has completed the last row, but the other gun bars Continuing to print the row on the material that precedes the row. When such a last row reaches gun bar #2, it receives color from this gun bar to the different sections of that row, and then while this row continues to move towards gun bar #3, the gun Bars #1 and #2 do not print since the last row has passed through these two gun bars. However, gun bars other than #1 and #2 are printing columns preceding the last column. This process begins with the last column passing through the last gun bar,
This continues until all gun bars are no longer imprinted in their respective colors. Similarly, when starting to print the first repeat of a pattern, the gun bar is activated to print each color only when the first row of this first repeat passes under the gun bar. Apply to this first row according to the pattern data. Thus, the gun bars are sequentially deactivated or activated, respectively, when completing the printing of the last repetition or beginning the printing of the first repetition. An advantage of the prior art apparatus is that short lengths of one pattern can be printed economically and that one can quickly and economically switch from printing one pattern to another. This is because there is no need to assemble and disassemble the machine, including the gun bar, each time a new pattern is desired. The data for the different patterns is stored in a computer, which is programmed accordingly to perform the required number of repetitions for each pattern, such as a predetermined number of repeats of one pattern, then a predetermined number of repeats of the other pattern. The printing data is output until the number of repetitions is printed. Since only this programming is required, it is economical to print each of the various patterns in short bursts, and it is possible to quickly switch from printing one pattern to another. However, a drawback of this prior device is that as a result of the sequential stopping of the gun bars, gun bar #1 is unable to print a new pattern until the last gun bar used to print the previous pattern has finished printing. This means that the printing process cannot be started. A length of fabric equal to the sum of the problem distances of all the gun bars used in the pattern thus remains unprinted, resulting in wasted fabric. Such waste cannot be ignored. For example, a machine may be programmed to repeatedly print five different patterns three times each, and the dimensions of each pattern are 9′×
Suppose it is 12′. The sum of the distances between all gun bars used is approx. for each three repeated impressions.
Assuming 8' to 9', the waste of dough corresponds to about one repeat. The present invention has the advantage of eliminating this waste by printing the first repeat of a new pattern immediately after the last repeat of a previously printed pattern. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a new method for printing various patterns on fabric without wasting fabric between different patterns. Another purpose is to simultaneously print two different patterns on the fabric when switching from one pattern to another. Yet another object is to simultaneously print at least two different patterns in such a way that the two different patterns are formed on the fabric without any loss of fabric or gaps between the patterns. Yet another object is to store and process data for at least two different patterns in such a way that the two different patterns are formed on the fabric without loss of fabric or gaps between the patterns. Yet another object is to provide novel products, such as fabrics, with different patterns extending along the length of the material. These and other objectives are achieved by storing at least two different patterns of data in one or more mass storage means within the computer. A first buffer within the computer stores a number of columns of first pattern data for a number of column requests, each column having data for a gun bar. A second buffer within the computer stores a number of columns of second pattern data for a number of column requests, each column also having data for a gun bar. The machine storage system disclosed in the electronic control system of the prior application applies a gun to one row of requests for applying color on fabric.
Temporarily stores one column of data for the bar. In operation, one section of the first pattern data from the mass storage means is transferred to the first buffer means. For each movement of the scheduled amount of cloth, a column request is generated and one column of data for the gun bar is
From the damping means, this data is passed to machine storage, from where this data is used to control each gun bar, i.e. to "fire" the gun bar or fire each of the fabrics under the gun bar according to the data. Output for applying dye to columns.
While the first pattern is being repeatedly generated by continuously loading the first buffering means with the first pattern data, the second pattern data is prepared for transfer to the machine storage for each column request. . A counter can count the number of repeats of the first pattern to be formed. When the last row of the last repeat of the first pattern is completed by gun bar #1, the data for gun bar #1 is transferred from the second buffer to the machine.
data for the remaining gun bars is transferred from the first buffer means to machine storage, thereby controlling the gun bars to produce different patterns simultaneously. This process continues such that as the first row of new patterns is moved under additional gun bars, more and more data is transferred from the second buffer and less data is transferred from the first buffer. do. When such a first row passes the last gun bar, data is retrieved only from the second buffer means, and the first buffer means is such that when the last line of the last repeat of the second pattern passes the last gun bar #1 Similarly, when passing through the machine, the data of the third pattern is sent to the machine.
Prepared to be sent to storage. A second counter counts the number of repetitions of the second pattern and determines when to switch to produce a new pattern. An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a jet type printing apparatus for printing patterns on textile products such as pile carpets. The apparatus has a source roll 10 from which the rolls of pile carpet 12 are unwound in succession onto a feed roll 14 and then onto the upper end of an endless inclined conveyor 16 of a jet dyer 18, where the carpet is subjected to a number of applications. Appropriately imprinted by means or programmed action of jet gun bar 20, the gun bar distributes a stream of dye or other liquid onto carpet 12 as it passes. The imprinted carpet leaving the dyeing machine 18 passes over rollers 22, 24 and into a steam chamber 26 where the carpet 12 is exposed to a steam atmosphere which causes the dye to set on the fabric material. The carpet is then conveyed to a wash room 28 to remove excess dye, then passed through a hot air dryer 30 and wound onto take-up rolls 32, and the dried carpet is stored for subsequent use. Further details of the apparatus that may be helpful in understanding the invention are shown in FIGS. 2-4. FIG. 2 is a schematic enlarged plan view of the jet dyeing machine 18, in which the endless conveyor 16 moves in the direction of the arrow, its support chains and sprockets (not shown) are appropriately supported on rotating shafts 34, 36, and the conveyor 16 moves in the direction of the arrow. One 36 is driven by a motor 38. During conveyor travel, the carpet 12 is provided with substantially identical gun bars 20 spaced apart along the conveyor transition path and extending across its width.
each gun bar containing a different color of dye or other liquid. Although eight such gun bars (#1 to #8) are shown in the drawings, any number of gun bars may be used depending on the number of colors required for the pattern. Although only one gun bar 20 is shown in Figures 3 and 4 for clarity, it can be seen that each gun bar delivers dye in a thin stream to the surface of the carpet 12 passing nearby. It has a number of individual injection holes 40 along its length that are positioned to face each other. Each gun bar 20 has a dye supply manifold 42 (FIG. 4) communicating with the injection holes 40, which is supplied with liquid dye from a respective dye reservoir 44. A pump 46 pressurizes and delivers liquid dye from the reservoir 44 to the manifold 42 and injection holes 40. During operation, the liquid dye is continuously discharged as a small stream or jet from the injection hole 40 towards the material to be printed. Disposed orthogonally adjacent each injection hole 40 is an outlet 48 of an air supply tube 50, each tube 50 connecting to an individual solenoid valve 52 (FIG. 4). The solenoid valve 52 is suitably supported within the jet dyer 18 and is supplied with air from an air compressor 54 (FIG. 4). Although the valves for each gun bar are shown in Figures 2 and 3 by a single valve symbol 52, the solenoid valves and individual air supply lines are designed so that each individual flow of dye is individually controlled. , are provided for each injection hole of each gun bar as shown in FIG. The solenoid valve 52 is controlled by a pattern controller or electronic controller 56 to impinge a normally directed air stream against the continuously flowing dye stream.
The dye stream is caused to be deflected into a collection box or trough 58 from where the dye is recycled to reservoir 44.
A control device 56 for operating the solenoid valve receives pattern data from a computer 60;
the computer stores data for at least two different patterns and provides a repeating array of data for one pattern, which is sent to a solenoid valve until the desired number of repeats have been printed;
A repeating sequence of data for the other pattern is then applied to the solenoid valve until the desired number of repeats have been printed. The control device 56 controls the carpet 12
passes under the gun bar 20 when the computer 60
is activated periodically to request pattern data from. The pattern data is processed by controller 56 and sent to solenoid valve 52 which opens and closes the valve to print the desired pattern on carpet 12 passing under gun bar 20. Assuming that the electronic control unit 56 is not processing any pattern data in the operation of the apparatus of FIGS. 2-4, the dye stream under pressure is supplied as a continuous stream from each injection hole 40 toward the carpet. .
However, all solenoid valves 52 are normally open to provide impinging airflow to the continuous dye flow, and all dye flow is connected to the trough 5 for recirculation.
Deflect into 8. As the carpet 12 passes under the gun bars 20, the electronic controller 56 is activated periodically so that some of the normally open solenoid valves 52 for each gun bar are closed in accordance with the pattern data. The responsible dye stream impinges directly on the carpet without being deflected. Thus, by opening and closing the solenoid valves in the desired sequence, the desired dye pattern is placed on the carpet as it passes under gun bar 20. The dye must be placed in the exact desired location on the carpet for good pattern formation and matching. This means that when the carpet moves a predetermined amount on the conveyor 16, the computer 6
This is accomplished by periodically activating the controller 56 to request pattern data from zero. The apparatus for enabling data requests to the electronic controller 56 is shown in FIGS. 2-4 and is operatively coupled to the rotary shaft 36 via a gear 64 for converting the mechanical motion of the conveyor 16 into electrical signals. a converter 62;
It consists of an electronic recording device 66. Details of the device enabling electronic control unit 56 are disclosed in US Pat. No. 3,894,413 (July 15, 1975). As shown therein, the transducer 62 and the recording device 66 are connected to each tenth of the conveyor 16.
It functions to generate an enable pulse every inch (2.5 mm) of movement, which pulses are sent to the controller 56. The device 56 is thus enabled to request and receive pattern data for dispensing dye on each 1/10 inch movement of the conveyor 16. The control device 56 is disclosed in the aforementioned earlier application, U.S. Patent No.
4033154 and is described in detail therein. Essentially, for each 1/10 inch movement of conveyor 16, in response to an enable pulse, device 56 receives from computer 60 one block or group of pattern data as a serial bit stream, the group consisting of eight bits. Each subgroup is distributed to one of each of the eight gun bars #1 to #8. Each subgroup consists of a number of bits equal to the number of valves 52, whereby each bit controls the opening and closing of a valve. Thus, each subgroup contains pattern data for a different row of carpet 12 under a respective gun bar 20. The present invention for printing at least two patterns on a carpet 12 with no gaps between the different patterns uniquely processes data within a computer 60 and transmits the data as a serial bit stream from the computer 60 to an electronic control unit. 56 in a timely manner. That is, the computer 60 has two
When data is stored for two different patterns and when switching from printing one pattern to another, the computer transfers several groups of data to the control unit 56, each such group having data for both patterns. It has subgroups of data for each. Thus, whether the control device 56 receives a group of data from a computer for printing one pattern, as described in the prior application, or it receives a group of data for printing two different patterns at the same time. At this point, device 56 functions and operates to distribute data to the gun bar. Therefore device 5
It is recognized that further details of No. 6 are not necessary for an understanding of the invention. FIG. 5 schematically shows an example in which the device of the prior US Pat. No. 4,033,154 has been in use for more than one year. This figure is described as having a pattern requiring eight colored gun bars. Inside the computer 60, a mass storage device 68, such as a disk, stores pattern data for a pattern to be printed. The pattern data is logically grouped by pattern rows on disk 68, i.e. each row on the disk contains data for gun bars #1-#8 and thus for a different pattern row on the carpet. It has a group of data. Each gun bar is adapted to print substantially simultaneously. Therefore, the data in a group for each gun bar must be for each pattern row on the carpet defined by the distance between the gun bars. For example, if the distance between the gun bars is 150 pattern rows, one group in one row on the disk is gun bar #1 data for pattern row 1400, pattern row
Gun bar #2 data for 1250, pattern row 1100
It consists of gun bar #3 data for pattern row 950, gun bar #4 data for pattern row 950, etc. This means that the pattern is at least 1400 pattern rows long. Computer 60 has within its core a buffer 70 which temporarily stores a section of data consisting of several groups of data sent to the buffer from disk 68. Each data group consists of eight subgroups A-H for respective gun bars #1-#8. Upon receiving each column request (i.e., enable pulse) from storage 66, controller 56 requests data from computer 60, and a group of data is then sent from buffer 70 to machine storage 72 within device 56. ,
Data is temporarily stored here and then sent to the gun bar. The machine storage 72 corresponds to the distributor of the prior application. There are two counters 76 inside the computer 60,
There are 78. Counter 76 is set to a count equal to the maximum number of columns from disk 68 that can be stored by buffer means 70, and the count is decremented by one each time a column of data is sent to machine storage 72. Counter 78 is set to a count corresponding to the number of repeats of the pattern to be printed, and the count is decremented by one each time the last section of pattern data is used to complete the pattern. Similarly, the computer program causes each gun bar to stop applying dye to the carpet when the last repeat of the pattern is being completed by subtracting the submersible material stored in the buffer means 70. Clearing data from one or more of groups A-H in a timely manner. In operation, assume that a section of data from disk 68 is stored in buffer means 70. When conveyor 16 moves 1/10 of an inch, controller 56 receives a request for a column from recorder 66 and sends a signal on line 84 requesting data from the computer. At this time, a group of data is transferred as a whole in a serial bit stream from buffer means 70 to machine storage 72, which in turn transfers the data to each gun bar #1.
~ Send to #8. This group of data
After being sent to storage 72, counter 76 is decremented by one. Whenever counter 76 is zero, thus indicating that all data in buffer 70 has been used, pattern data from the next section on disk 68 is sent to buffer 70. . Whenever the last section of pattern data on disk 68 is used, the count in counter 78 is decremented by one. When counter 78 indicates a need for a greater number of pattern repeats, the first section of pattern data is sent to buffer means 70 and the same process continues for printing another repeat. If counter 78 is equal to zero, this indicates that the last repeat is being printed and that the gun bar should be stopped from "firing" in sequence. This sequential termination of firing is performed by buffering means 70 before the data is sent to machine storage 72.
This is accomplished by a computer program that timely clears the data within. Thus, if the last pattern row of the last iteration just passed gun bar #1, the next group of data to be sent to storage 72 in a row request would be 0 joining subgroup A and subgroup B Data remains in ~H. Thus, gun bar #1 does not fire, while the other gun bars are firing and applying dye to the rows on the carpet preceding such last row according to the pattern data. 0 is forced into subgroup A only in each group stored in buffer means 70 until the last column of the last iteration passes through gun bar #2. 0 is then added only to subgroups A and B of each group, causing gun bar #2 to also stop firing, while the other gun bars #3 to #8 continue to fire according to the pattern data. This process continues until the last row of the last iteration passes gun bar #8, at which point all gun bars stop firing. The computer is then programmed to prevent data from being sent to storage 72 even if a queue request is issued due to continuous movement of conveyor 16, unless a new pattern is to be printed. All solenoid valves 52 are thus returned to their normally open condition, preventing dye from impinging on the carpet 12. If desired, the mass storage means 68 of FIG.
Pattern data regarding at least one other pattern to be printed is also stored. When the last repetition of the first pattern has been printed and all gun bars have stopped firing in sequence, the buffer means 70 prints a new pattern by sequentially starting to fire the gun bars. The pattern data to start the process will have been accumulated. When the first row on the carpet of the first repeat passes gun bar #1, subgroup A is sent from buffer means 70 to storage 72 and then to gun bar #1. Since subgroups B to H will have been cleared from the data in buffer means 70, gun bars #2 to
#8 does not fire. This continues until the first row of the first repeat of the new pattern passes under gun bar #2, at which point storage 72 receives subgroups A, B from buffer means 70 and transfers them to gun bars #1, #2. are fired respectively, and the other gun bars do not fire because subgroups C to H are cleared with 0, and in the same manner, the necessary gun bars fire according to the data they receive, completing the start. It continues until Thus, when switching from printing one pattern to another, the conveyor 16 moves continuously to generate queue requests, but the various patterns are not printed at the same time. The result of sequential cessation of gun bar firing is 6A.
As shown in the figure. There is a gap on the pile carpet equal to the distance between gun bar #1 and gun bar #8, resulting in material loss. When starting different patterns, there is a gap between the first repeat of this pattern and the last repeat of the previous pattern. FIG. 6B illustrates the advantages of the present invention. When switching from printing one pattern to printing another pattern,
There is no loss because there is no need for blank spaces on the carpet at the joints of the pattern. However, in the present invention, small gaps can be provided between different patterns to allow cutting without damaging any of the patterns. Figures 7, 8 and 9 schematically illustrate various modes of operation of the method of the invention. In order to print a certain number of repetitions of one type of pattern, a mass storage means or disk 6 is used.
8. Buffer means 70 and counters 76, 78 and zero source 80 and counter 82 as shown in FIG.
(calculates the number of gun bars used for pattern imprinting) is used. Source 80 is a number of logic zeros stored in the core, which number is equal to the number of data elements that make up the firing instructions for one gun bar. In addition, a second mass storage means 86, such as a disk or the like, for storing data for other patterns; other buffering means 88 for temporarily storing sections of data from the disk 86;
A counter 90 for counting the number of columns of data in the buffer means 88, a counter 92 for counting the number of repetitions required for other patterns, and a gun used for printing other patterns. A counter 94 is also used to count the number of bars. FIG. 7 shows a mode of operation for printing several repetitions of one type of pattern. This one pattern uses, for example, eight different colors, so data is required for eight gun bars #1-#8.
Assume that a section of data from disk 68 has been stored in buffer means 70 and gun bar starting has been completed. When conveyor 16 moves 1/10 inch, controller 56 receives a row request from recording device 66 and sends a signal on line 84 to computer 6.
0 to request one group of data. At this time, one column of subgroup data A of the data in buffer means 70 for gun bar #1 is sent to machine storage 72. Once this operation is complete, subgroup data B in this row for gun bar #2 is sent to machine storage 72;
Once data B is stored in storage 72, subgroup data C is then sent to storage 72, and so on until all columns or groups of data have been sent to storage 72. This effect should be contrasted with what has been described above with respect to FIG. 5, where all data in buffer means 70 was simultaneously transferred to storage 72 upon receiving a queue request. The transfer of each subgroup's data from the buffer means 70 to the storage 72 is monitored by a counter 82 which determines the number of gun bars used to print a particular pattern, i.e. the subgroup's data A~
It is set to a count corresponding to the number of H's. As each subgroup is transferred to storage 72, counter 82 is adjusted accordingly, and when it indicates that all data in a group has been transferred to storage 72, counter 76 is The subgroup or column data is transferred from the buffer means 70 to the machine.
The storage 72 is emptied, the buffer 70 is adjusted to indicate that it is completely empty, and a new section of data is selected from the disk 68 and sent to the buffer 70. When the last row of the last repeat of the pattern being printed passes under gun bar #1 and no new pattern is requested, gun bars #1 through #8
It's time to start sequentially stopping them from firing. Now, instead of clearing the data for the appropriate gun bar in the buffer means 70 as was done in the case of FIG. That's what I do. Thus, when the last row of the last repeat passes only through gun bar #1, source 8
0 provides a 0 to the section of storage 72 storing data A, and data B-H from buffer means 70 are sent to the remaining sections of storage 72. This continues until the last column passes through gun bar #2, at which point source 80 supplies zeros to the section of storage 72 storing data A and B, and sections C-H are removed from buffer means 70. Pattern data is received and so on until source 80 supplies zeros to all sections of storage 72, thus sequentially stopping firing of all gun bars #1 through #8. FIG. 8 shows the mode of operation when a switch from one pattern to another is required. Prior to switching, a type of pattern repeat occurs in the same manner as described with respect to FIG. While one pattern is being formed by the gun bar, another pattern is being prepared by sending a section of data therefor from disk 86 to buffer means 88. When the last row of the last repeat of a pattern is completed by gun bar #1, data A for gun bar #1 is sent from buffer means 88 to machine storage 72 while the remaining Data B-H for gun bars #2-#8 are sent from buffer means 70. As already mentioned about the effect in Figure 7, the data is
The data is sent from the buffer means 88, 70 to the storage 72 in subgroups. This continues until the last row of the last repeat of one pattern is completed by gun bar #2, at which point data A and B are sent from buffer means 88 and data C-H are sent to buffer means 7.
0 to the storage 72. This process continues such that the last repeat of the first pattern is located under an increasingly fewer number of gun bars and the first repeat of the second pattern is located under an increasingly larger number of gun bars. As this occurs, more and more pattern data is taken out from the buffer means 88, and conversely, less and less pattern data is taken out from the buffer means 70. Figure 8 shows an example in which one type of pattern uses all eight gun bars, and another type of pattern uses only four gun bars. Therefore, buffer means 88 only stores data of the four subgroups A-D. 8th
The figure also shows an example where one type of pattern is under gun bars #5-#8 and another type of pattern is under gun bars #1-#4. Therefore, at this point, the information for the four gun bars is stored in the buffer means 88,
70 respectively. Figure 9 shows an example where one type of pattern is moving under gun bars #6 to #8 and the first repeat of the other type of pattern is moving under gun bars #2 to #5. .
Gun bar #5 must not fire at this point. This is because the other pattern rows below this gun bar have already received their required colors from gun bars #1-#4. Similarly, Gun Bars #6-#8 must complete one type of pattern and Gun Bar #1 must begin firing for the next repetition of the other type of pattern. Therefore, at this point data A-D are sent from buffer 88 to storage 72 for gun bars #1-#4, source 80 provides 0 to storage 72 for gun bar #5, and data F ~H is sent from buffer means 70 to storage 72 for gun bars #6-#8. Thus, at this point, gun bars #1 to #4
and #6 to #8 fire according to data for other types of patterns and one type of pattern, respectively, and gun bar #5 does not fire due to data from source 80. When the pattern of other species moves under gun bar #6,
Storage 72 stores data A to D in gun bar #1.
.about.#4 from buffer means 88, 0 from source 88 for gun bars #5 and #6, and data GH from buffer means 70 for gun bars #7 and #8. This process continues until the last row of the last repeat of the first pattern finally passes gun bar #8, at which point storage 72 transfers only data A-D to buffer 8.
Receive from 8 for Gun Bars #1 to #4. In such a case, source 80 does not supply a zero for gun bars #5 to #8, but these gun bars do not fire as if they had received a zero. This is because the solenoids 52 for these gun bars are in their normally open position. After switching from printing one type of pattern to another type of pattern, the other type of pattern is printed a predetermined number of times in the same manner as for the previous pattern. The counter 94 receives data A to D of subgroups of the group in the buffer means 88.
, and the counter 90 is adjusted to one group of data being transferred to the storage 72.
When counter 90 indicates that buffer 88 is nearly empty, a new section of data from disk 86 is sent to buffer 88. Each time the last section of this data is used, counter 92 is decremented by one, and when this counter indicates that the last section of the last repeat of the other pattern has been used, the gun bar is 0 from source 80 to storage 72 at the appropriate time as already mentioned.
By forcing them to join, the firing is stopped sequentially. In the above example, when switching patterns, there is a switch from using a large number of gun bars (8 pieces) to a small number of gun bars (4 pieces), and the source 8
0 had to be supplied during switching. However, if there is a change from using a smaller number of gun bars to a larger number of gun bars when switching patterns, source 80 supplies 0 during the change as it does when the reverse is true. There's no need to. Similarly, in the present invention at start-up (as at all other times) the source 80 does not clear data from the buffer means 70 as described with respect to FIG. Instead, only data for subgroups is stored in storage 72 depending on the number of gun bars that the first column of the first iteration passes.
sent to. According to the invention, therefore, the source 80
provides 0 only when sequentially stopping gun bar firing and when switching from using a larger number of gun bars to a smaller number, with one exception as described below. be. What has been described above is a mode in which no gap is created on the carpet when switching from one type of pattern to another. However, the present invention has the ability to create a specific amount of white space between patterns. Several rows of white carpet between the patterns can be used for cutting to separate the different patterns. This specific amount may occur by delaying the sending of data for the new pattern to gun bar #1 to storage 72 when a pattern switch occurs. In lieu of such data, source 80 can supply a zero to storage 72 to prevent gun bar #1 from printing a new pattern for a predetermined amount of pattern rows on the carpet, e.g., 30. . Although the two large-capacity storage means 68 and 86 were described above, the pattern data can be stored permanently in a single large-capacity storage means, but the data for each pattern can be accessed as appropriate. section to the buffer means 70,88. Further, although two different patterns of printing have been described, any number of different patterns of printing are possible, as will be described later. Additionally, although buffer means 70 and 88 are shown as single elements, they each consist of two buffers. Each of these two buffers takes turns as both an input buffer and an output buffer. When data is sent from a buffer to storage 72, it is an output buffer, and when data is ready to be transferred from disk to the buffer, it is an input buffer. Next, the present invention will be explained in more detail with reference to Tables 1 to 4 and the flowcharts shown in FIG. 10 and below. Tables 1-4 are tables and lists of variables used in processing pattern data according to the present invention. The first table is a pattern table listing specific items used for each pattern stored on the disk 68. This pattern chart is inserted into the computer 60 before starting the first printing of the desired pattern, and contains five entries (1) to (5) of digital words representing specific information for each pattern as follows. I have it too.

[Table] (1) is the number of gun bars used, (2) is the disk address, (3) is the length of the pattern, (4) is the number of repeats, (5)
is the width of the pattern. The number of gun bars used is the maximum number of gun bars that will receive pattern data from disk 68 to print a particular pattern. For example, if the pattern requires only three colors, the dyes would be stored in gun bars #2, 3, and 6, respectively. Therefore, the number of gun bars used is six. In addition to the above three pattern data, pattern data for #1, 4, and 5 is also stored on the disk 68. However, the pattern data for the latter three is to prevent gun bars #1, 4, and 5 from firing, and they are all 0. Gun bars #7 and 8 receive no pattern data and are not activated to fire. Why gun bars #1, 4, 5 instead of #7-8?
The reason why must receive 0 as pattern data is as follows. With reference to FIG. 7, data is sent, for example, from buffer means 70 to machine storage 72 sequentially gun bar by gun bar. If the buffer had data only for gun bars #2, 4, and 6, the data for gun bar #2 would be sent to location A of storage 72, and then the data for #3 would be sent to location A of storage 72. It will go into the B position and then #6 data will go into the C position. Thus, cancer
Bars #1-3 end up receiving data intended for #2, 3, and 6. By preparing 0 as part of the pattern data, #2, 3, and 6 that are scheduled to fire will fire, and #1, 4, and 5 will not fire. Since storage 72 has stored the proper pattern data for gun bars #1-6, no pattern data is needed in the storage locations corresponding to G and H, so gun bars #7-8 will not fire. The width of the pattern is the word count times the number of gun bars used. The word count is constant and equal to the number of computer words consisting of the number of bits required to control valve 52 for one gun bar. Therefore, the word count is, for example, the number of words comprising subgroup A.

TABLE Table 2 is an output table containing the information necessary to send the "current" column or group of data from the output buffer to storage 72 when a column request is received. For example, in the pattern table (Table 1), 6
Two patterns can be set, but in the output table, pattern #1 and pattern #2 (for example, pattern #4 in the pattern table) can be set.
Only the information for the two patterns (patterns 1 and 5) is shown. Both patterns #1 and #2 have four entries (1)-(4) of digital words representing certain information. (1) is the number of gun bars that output, and is the number of gun bars that receive pattern data from the output buffer. (2) is the column address, which represents the location in the output buffer of the first word of the particular column of data at the time the column request is made (this column is referred to as the "current" column). (3) is the word count for one gun bar, and (4) is the first gun bar to output, the first gun bar in the current row to receive the pattern. For example, in FIG. 9, when the first pattern is below gun bars #6-8, the number of gun bars to be output is 3, and the first gun bar to be output is #6. The second pattern is now below gun bars #2-5, and the number of gun bars output for this pattern is 4 (3 #2-4 for the first repeat, #3 for the second repeat). 1), the first gun bar to output is #1. Table 3 Variables/counters for pattern #1 and pattern #2 (1) Number of repeats (2) Number of first column in input buffer (3) Pattern length (4) Disk address (5) Number of Columns Requested Table 3 is a list of variables/counters for Pattern #1 and Pattern #2, each in digital words (1) number of repeats, (2) first column in the input buffer. number, (3) pattern length, (4) disk address,
(5) Represents the number of columns requested from the output buffer. (2) is the number of the first column or group of data in the section sent from the disk 68 to the input buffer; for example, the first column is the number of columns of data stored in the disk for a particular pattern. It could be number 50. The number of rows requested after the input buffer switches to become the output buffer may be 52. Of the information in Table 3, everything except the pattern length is a variable. In order to simplify the explanation, FIGS. 7 to 9 are illustrated and explained as including counters 76, 78, 82, 90, 92, and 94, but in reality, counters 78 and 92 are included.
Only a counter that can count the number of printed repetitions,
The other "counters" are not counters, and in standard computer program practice, the information on these "counters" is when the buffer is empty, 76, 90,
and a value representing a means for determining 82,94 how much data to output to storage 72. Table 4 System variables (1) Stop counter (2) Start counter (3) Stop length (4) Start length (5) Pointer to current pattern #1 in pattern table (6) Stop Data flag (7) Stop request flag (8) Start request flag (9) Pointer to input buffer (10) Pointer to output buffer (11) Delay length (12) Delay count Table 4 A list of system variables located within the computer 60 that includes (1) counts of stop and (2) start counters (not shown), (3) stop length, and (4) start length. . These lengths vary depending on the number of gun bars used for a particular pattern, and the information stored in the start and stop counters is
It is used to start each gun bar that prints a pattern and to stop printing such a pattern. (4) The start length is the number of rows on the carpet that the first row of the pattern must pass through gun bar #1 before passing through the last gun bar; (3) The stop length is the number of rows on the carpet that the pattern must pass through before it passes through the last gun bar. the gun before the last row passes the last gun bar.
The number of rows on the carpet that bar #1 should pass through. For example, to start or stop the pattern printed by gun bars #1-5 (assuming each gun bar is 150 pattern rows apart), the length of start and stop is 4 x 150 = 600 rows. be. As each of the first 600 rows passes under gun bar #1, the starting count on the start counter is decremented by 1, and when it reaches a count of 600, it is fully started and starts from gun bar #1 to
5 fires. As each of the first 600 columns following the last column of the last repeat pass through gun bar #1, the stop counter decrements by 1, and when it reaches a count of 600, it stops completely and passes through gun bar #1. 1 to 5 do not fire. The system variables further include (5) pointer to the current pattern #1 in the pattern table, (6) stop data flag, (7) stop request flag, (8) start request flag, and (9) input buffer. (10) output buffer pointer, (11) delay length, and (12) delay count. FIG. 10 shows in a flowchart the preparation for printing the first repeat of the first pattern and the start of a program for maintaining the input buffers of buffer means 70, 88 full of pattern data. disk 6
For example, 100 patterns can be stored on 8. Prior to starting, the operator selects a certain number of these patterns and sets up a pattern table with five entries for each. After completing the pattern chart, the program will start.
First, the system is initialized (100). Set the current pattern #1 pointer to point to the first pattern in the pattern chart. The input and output buffer pointers of means 70, 88 are initialized so that each points to one of the four buffers. Set the start and stop counter to -1 so that there is no start or stop at this point. Clears the stop data flag so that data is sent from the output buffer when a queue request is received, and clears start and stop request flags that are controlled by the operator. When starting any pattern at any time, this pattern is treated as pattern #2 (102). After the start is completed, this pattern is treated as pattern #1 (with one exception, which will be described later).
Therefore, after the machine has been initialized (block 100), the first pattern in the pattern chart is treated as the second pattern during start-up of the dyeing machine 18 (block 102). Therefore, the pointer for the current pattern #1 is reset to point to the temporary pattern number 0 (does not exist) in the pattern table. The start counter is then set to 1, indicating that pattern #2 is to be started (104). The first pattern in the pattern chart is now initialized as pattern #2 (106), which is performed by the subroutine of FIG. That is, the entry for pattern #2 in the output table is set (block 106a). The number of gun bars set to output=0 ensures that the gun bars do not fire at this point. The word count is recorded in the output table and the first gun bar to output is set equal to #1 for when to begin printing repeats of pattern #2. The number of repetitions for this pattern #2 is set, for example, in a repetition counter 78 (block 10
6b), this information is obtained from the pattern chart. A copy of the pattern length and disk address is then made from the pattern table for later use (block 106).
c). The number of columns to be requested from the output buffer from buffer means 70 is set to -1, and the number of first columns in the input buffer of buffer means 70 is set to 0 (block 106d). Information about the disk transfer is then awaited (block 106c) so that the disk transfer of the data to the input buffer of the buffer means 70 can occur at an appropriate time. This includes populating the list with the disk address copied for pattern #2 and the buffer address that tells where buffer means 70 is located within the core of computer 60. The subroutine is thus completed and the program returns to the main program (block 106).
f). As shown in FIG.
The step is to obtain a column address for pattern #2 for column output (108). This is the first
This is executed by another subroutine shown in FIG.
The number of columns to be requested in the output buffer of means 70, which was set to -1 in block 106d of FIG. 11, is increased by 1 to 0 (reference numeral 108a). If the number of columns to be requested in the output buffer of the means 70 (or 88) is equal to the number of the first columns in the input buffer (these are the input and output buffers during initialization, These pointers are switched so that the output buffer becomes the input buffer and vice versa (108b).The adjustment of the number of columns (108c) can be done, for example
This means that the input buffers, which can have 33 rows of abilities, must be kept full at all times.
If, for example, the pattern length were 100, the output buffer could store columns 98-100 and columns 1-30 for the end of one repeat and the beginning of the next. When we read this data from the output buffer, the number of columns we need to request goes from 98 to 130. The next section of data stored in the input buffer begins at column 31. Therefore, instead of increasing the number of required columns to 131, we adjust it to 31. Next, the number in the first column in the input buffer and the disk address are calculated (108d) as follows.
This is to determine where within disk 68 a new section of data should be sent. The number of columns is the number of the first column in the output buffer + the number of columns of data that can be stored in the output buffer (if the first column is 0 and the number of columns that can be stored is 33, then the input The number of the first column in the tubatua is
33). The disk address is equal to the first disk address given to the pattern chart + (pattern width x number of first columns in input buffer). This determines how many words down the disk from the first disk address is the first word of the new section of data to be sent to the input buffer. The transfer from the disk 68 to the input buffer of the means 70 is then set (108e) to begin with the calculated first column number, and this is set to include the calculated disk address and buffer address or other data. waiting (108(f)) to transfer the section of There are two waits for disk transfer of data to the two buffers.The column address for the current column stored in the output buffer is then computed (108).
g). Calculating the column address is done by knowing the number of the first column in the output buffer and the number of columns to be requested when a column request is received. The column address is obtained by subtracting the number of first columns in the output buffer from the number of columns to be requested (obtained from 108a) and multiplying this by the width of the pattern. So, for example, if the number of first rows is 50 and the number of rows to be requested is 60, the difference is 10, multiplied by the width of the pattern. For the beginning of the first pattern (block 106), these two numbers are zero. This gives the position of the first word of the current column in the buffer. The buffer address is then added to such number to give the absolute location of the first word within the core. Then, enter the column address in the output table (108h) and return to the main program (108h).
08i). Returning again to FIG. 10, the starting length for pattern #2 is set, and its value is shown in block 110. Next, set the number of gun bars to output for pattern #2 on the output table (1
12). When the first row of the first repeat of pattern #2 passes under gun bar #1, only this gun bar should receive pattern data. Therefore, in such a case, from 70 output buffers, 1
There is data that is sent only to one gun bar. The program then enables the computer to receive a start-stop interrupt initiated by the operator pressing a start or stop button (block 114). Before continuing, the program waits (block 11) to see if the operator has pressed the start button to begin printing the pattern.
6) If there is no start, the program continues to wait.
If there is a start and the disk 68 is not busy transferring data to one of the buffers 70 and the transfer of data from the disk 68 is already requested, then for pattern #2 the transfer of data from the disk is Transfer is initiated (block 118) (at the first start of the first pattern in the pattern chart, transfer is only made for pattern #2, but at other times pattern #1 and/or pattern #2). The transfer is required by the presence of the disk address and buffer address created by the standby effect described above, so that when the transfer begins,
One of the means 70 specified by one of the standby effects
Data will be transferred to two buffers. When the transfer begins, the disk is set to busy (block 1
12), the computer is enabled to process the queue request interrupt (block 122), and the program then waits for any interrupt (block 124). The interrupt can be a signal that a disk transfer is complete, or a queue request, or the result of an operator pressing a start or stop button. Block 118, 120, 122, 124, 1
The loop containing 30 is a loop that is executed when a return from an interrupt occurs to see if a disk transfer is requested. Therefore,
When an interrupt occurs, the program can be at any point in the loop, and execution of the loop is temporarily halted. As soon as the interrupt is processed and returns from the interrupt, execution of the loop continues. As shown in Figure 10, when the disk transfer is complete and there are no errors in the transfer, such as when one of the wait operations has finished processing, the disk is then set to uncongested (block 126) and the returns (block 128). If there is an error, a message will be printed and
The program is stopped (block 132). If there is a return from interrupt after the disk transfer is complete for one wait action (block 128), the disk will become uncrowded and the other Transfer is requested. Therefore, the transfer is initiated by another waiting action (block 11).
8), the disk is set to congested (block 1
20), the line handling the queue request interrupt is enabled (block 122) and waits for another interrupt (block 124). If the disk is busy but no transfer is requested, no transfer is initiated and the program waits for an interrupt (block 124). About the start of the first pattern in the pattern chart
When the disk transfer of is completed, the buffer of means 70 has the data accumulated for pattern #2;
Computer 60 is ready to process a queue request when it is received. The flowchart for handling a queue request interrupt is shown in 13.
Shown in Figures A, B, and C. If a queue request is received, the queue request is inhibited, and the queue request is inhibited, assuming that the transfer of data from the output buffer of means 70 to machine storage 72 is halted due to the stall data flag. The flag is cleared (block 132). There is then a wait for start (block 134), which occurs when the operator presses the start button (described below with respect to FIG. 17A). A start results in a return from interrupt (block 136). If there is no stop data flag, its start is 1
The column data should be transferred from the output buffer of the means 70 to the machine storage 72 (block 138). The interrupt is simulated (block 137). Here the program is
Now you are ready to output one column like this,
This is illustrated in Figure 14, a flowchart for outputting one column from the output buffer. In the discussion of this flowchart, assume a start condition and remember that at the start of the first pattern in the pattern chart there is no pattern #1 and the gun bars are turned on sequentially. At the start of the first pattern, there is no data to be output to the machine thread 72 for pattern #1, this information is obtained for pattern #1 from the output table, and the gun information to be output is
The number of bars is shown as 0 (block 112). There is data to be output to machine storage 72 for pattern #2, and this information is obtained for pattern #2 from the output table, indicating that the number of gun bars to be output is one (block 112). Therefore, the output of the subgroup of data for gun bar #1 begins, beginning with the column address obtained from the output table for pattern #2 (block 140). The output buffer pointer then points to the next subgroup of data in this column by calculating the column address for the next subgroup (block 142). The next column address for this subgroup is now equal to the column address for the current subgroup plus the word count. After pointing to the next data subgroup, upon return from the interrupt (block 144), the gun is removed from the output buffer of means 70.
Waits for the transfer of the current subgroup of data to machine storage 72 for bar #1 to be completed. Means 70 per gun bar #1 for pattern #2
From the output buffer to machine storage 7
When the transfer of data to 2 is completed, there is a data interrupt as shown in FIG. At this point, the program determines whether data must be sent to machine storage 72 for any other gun bars. At this point in the start, the output table for pattern #2 indicates the number of gun bars to be output as 1, and this number is decremented by 1 as data output begins (block 140). Therefore, the number of gun bars to be output in the output table is 0, indicating that all data for pattern #2 has been transferred to machine storage 72. If all data in the current column of the output buffer has not yet been transferred to machine storage 72, the output table will not set the number of gun bars to be output to 0 (as will be clear from the explanation below). block 14) and this additional data is transferred to machine storage 72 (block 14).
0,142,144), a data interrupt will occur after each transfer is completed. When all data in the current column has been sent from the output buffer of means 70 to machine storage, the next problem is that some logic 0 is
It depends on whether it is requested by. As previously mentioned, this is only necessary when changing from a pattern using many gun bars to a pattern using fewer gun bars, or when stopping the pattern. Therefore, no zero is required from source 80 at the start of pattern #2. The next question is whether there is any data required from machine storage 72 for pattern #1. At the start of the first pattern, there is no pattern #1, and the number of gun bars to be output for it is 0 (block 11
The answer from 2) is NO, resulting in a return from interrupt (block 146). The program continues as shown in FIG. 13A while data is being sent from the output buffer of means 70 to storage 72. At this point in time at the start, the gun bar stop is not proceeding, so the process stop does not work (block 148). However, assuming there is no delay in progression (this delay is used to create small gaps between different patterns, as explained below), the initiation will proceed (block 150) and the flowchart for this will be described below. It is shown in FIG. The start counter is checked to see if it is zero, indicating that the start should begin, but this counter was initially set to 1 (block 104), thereby indicating that the start is in progress. shows. Since the starting counter is not zero, this counter is checked to determine when to fire the next gun bar (block 152). As mentioned above, one row on the carpet is Gun Bar #1.
The starting counter increments by 1 each time it passes through. The gun bars are 150 pattern rows apart, so the gun bars are 150 pattern rows apart.
After bar #1 starts firing, when it reaches a count of 150, it will indicate that gun bar #2 should fire pattern data. Thus, after gun bar #1 begins firing, gun bar #2 will not fire until the starting counter reaches 150, and the counter will fire as each row of carpet passes gun bar #1. Increase by 1. (Block 154) There is one exit for each increment of the starting counter (Block 156) and the program continues (Block 15).
(from 0). After exiting block 150 (Figure 13A), the program checks whether a stop is in progress. Since a stop is not currently in progress and a start is in progress, the program continues as shown in Figure 13C to obtain a new column address to output another column of data when the next column request is received. . The first decision box in Figure 13C asks if pattern #1 is the same as pattern #2. At the first start of pattern #2 to be printed, pattern #2
is not the same as pattern #1 (non-existent), and the answer is no. (Even when switching from printing one pattern to printing pattern #2 is not the same as pattern #1) Therefore, a temporary pointer used only in block 160 (not mentioned previously) is set to point to current pattern #2 in the pattern chart (block 158). Similarly, when the printing of one pattern is completed, the pattern stops, and the printing of another pattern begins, the temporary pointer is set to the current pattern in the pattern table. However, if the operator stops the process in the middle of executing a pattern, he must start the process with the same pattern to complete the pattern. Pattern #1 and pattern #2 will be the same under this condition. Therefore, a temporary pointer is set to current pattern #1 in the pattern chart (block 159). The manner in which a column address is thus pointed to by such a temporary pointer (block 16
0) It can be obtained by the routine shown in FIG. Referring to Figure 12, if the number of columns in the first column in the input buffer is not equal to the number of columns to be requested in the output buffer, the program returns the new column address in the output buffer. Proceed directly to the calculation of (block 108g). The new column address is then entered into the output table (block 108h) (starting pattern #2).
for). Get this new column address (block 16)
0), it is determined whether the end of one repeat is being printed, as shown in FIG. 13C. This is determined by comparing the number of rows to be requested to the pattern length of pattern #2. If they are equal, it is the end of the repeat and the repeat counter is decremented by one to indicate that another repeat is being printed (buffer 162) and a return from interrupt (block 164). If it is not the end of the repeat, the repeat counter is not decremented and returns from the interrupt. In this routine, gun bar #1 is started and new column addresses are continuously calculated, but this routine is performed for the first 149 pattern columns. When the starting counter registers a count of 150, gun bar #2 will change to gun bar #1.
With this, preparations for launch are completed. Therefore, referring to FIG. 15, it is now time to start the next gun bar, but this is not the end of the starting motion, nor is it past the end of the starting motion. Subsequently, the number of gun bars to be output in the output table for pattern #2 is increased by one (block 157), the start counter is advanced by one (block 154), and the number of gun bars to be output is increased by one (block 157).
6). Block 152, 154, 156, 157
The above procedure shown in is carried out for the next 149 pattern rows and thereafter, and finally the start operation comes to an end. In this way, if pattern #2 has 8 guns
When requesting a bar, the output table reads 8 when the first pattern row passes under gun bar #8. After the end of the start operation and after the output table has been adjusted to record the number of gun bars to be output (block 166), if no stop is in progress, the start counter = -1, it is set and the stop and start request flags are cleared (block 1
68). This is done prior to the production process of multiple iterations of pattern #2. The pointers are then exchanged so that pattern #2 is processed the same as pattern #1 and the next pattern to be performed in the pattern chart is set up as pattern #2 (block 17).
0). It is ready to switch to printing another pattern when the last repeat of the pattern currently being printed is completed. New pattern #2, like pattern #2 described above, is then initialized as shown in FIG. 11 and ready for data transfer from the output buffer of means 88 to machine storage 72 ( Block 172). The program then exits (block 174) from block 150 (FIG. 13A) and, assuming no stop or start is in progress, the column address for pattern #1 is transferred from the output buffer of means 70 into this buffer. The accumulated data is acquired in preparation for transfer to machine storage 72 (block 176). Once again, this column address is obtained as shown in the flowchart of FIG. Then 13th A, B
Referring to the diagram, after obtaining the column address, if a stop is not in progress, the machine is not at the end of a repeat of pattern #1, and a start is not in progress, an interrupt is issued at block 130 to process a disk transfer. (block 178). If a stop is not in progress and the machine is at the end of a repeat, counter 78 is decremented by one to indicate that the repeat is complete (block 180). If counter 78 is not 0 after being decremented by 1, another repeat of the pattern should be printed, and if no stop is requested and no start is in progress, any necessary disk transfers are performed. There is a return from the interrupt (block 178) to perform the change. If, after decrementing the counter 78 by 1, it is 0, then the predetermined number of repetitions of pattern #1 have been printed and the program prepares the data for switching to printing a new pattern. The stop length for pattern #1 (this is the pattern whose last repeat is now being printed) is set and is equal to (gun bar number used for pattern #1) x (two guns).・Number of pattern rows between bars) is equal to (block 182). The program sets the stop request flag to enable the stop operation and the stop counter is set to 0 (block 1
84). the stop is not requested by the operator,
Also, if all the patterns listed to be printed on the pattern table have not yet been printed, the delay length and delay counter are set to create a small gap between different patterns, if desired.
A start request flag is set to enable starting (block 186). The starting length of the new pattern (pattern #2) is set (block 18).
8), return from interrupt (block 178)
becomes. Since at this point the stop counter has already been set to zero (block 184), referring to FIG. 16, the start counter is set to zero in preparation for starting a new pattern to be printed. The last pattern line of the last repeat of pattern #1 passes through gun bar #1. Therefore, in the output table, the number of gun bars to be output for pattern #1 is reduced by one. Similarly, since gun bar #1 is not firing for pattern #1, the gun bar that should output for this pattern is gun bar #2, so this entry in the output table is incremented by one ( Block 1
92). The stop counter is then incremented by one to indicate that the stop is progress (block 194). The program then exits from block 148 (block 196) and, referring to FIG. 13A, if the start of a new pattern is not in progress and a stop is in progress due to a delay in progress to create a gap between different patterns. For example, the column address for pattern #1 is obtained to output the new column for the last iteration (block 176). This results in a return from the interrupt (block 178) to process the new queue request. Referring again to FIG. 16, if printing is stopped at the end of the last repeat, the stop counter will be ≠0 when the last row of this repeat passes gun bar #1. A stop counter is checked to determine if it is time to stop firing gun bar #2 (block 198). When the stop counter reaches 150, it is time to stop firing gun bar #2. Therefore, gun bar #2 is never closed for the first 150 rows counted by this stop counter. For each column, the stop counter is incremented by one and the program exits block 148 (block 196) to process the next column request. When gun bar #2 is fully closed and not at the end of the stop motion, the output table is adjusted (block 1
92) Indicates that the number of gun bars to be output is decreased by 1 and increased by 1 for the pattern where the first gun bar to be output is stopped. If it is the end of the stop operation, that is, all gun bars have stopped firing, the number of gun bars to output is set to 0 (block 200) and the output for the now closed pattern is set to zero. Indicates that no further data is available from Tutbatshua. The stop counter is set to -1 to indicate that no stop is in progress and the stop request flag has been cleared prior to any other stop request flag that may occur after restarting (block 2).
02). Then, if no initiation is requested, no further data should be sent to the gun bar. Therefore, the stop data flag is set to ensure that data is stopped (block 204) and the program then exits (block 196). If a start is requested after setting the stop counter to -1, the program exits (block 196). This start is now being processed (Figure 15), and since the start counter is now 0, the output table for pattern #2 is changed to show the number of gun bars to output for pattern #2. Gun bar #1 is adjusted to 1 (block 157) prior to this pattern being used at the start. Referring to FIGS. 13A and 13B, assume that the machine is printing a repeat of a pattern that is not the final repeat and the operator presses the stop button. The stop request flag is not checked until the end of the iteration, at which point counter 78 (or 92) is decremented by one (block 180). Since this counter is equal to 0 and a stop is requested, the start length and stop length are set equal to each other (block 2
06). These lengths will be the same because the pattern that was stopped is the same pattern that will be started to complete the process the next time the operator presses the start button. The stop counter is set to 0 to initiate a stop (block 208) and pattern #2 is set the same as pattern #1 to restart the same pattern (block 210). This pattern #2 is initialized as shown in FIG. 11 for restart. Repeat counter 78 for pattern #1 is then set to the count in one of 92 to the other counter for pattern #2 to complete the process as a pattern with the desired number of repeats (block 212). ). After setting these repeat counters, referring to Figure 13C, since pattern #2 is the same as pattern #1, the temporary pointer is set to current pattern #1, which is the previously stopped pattern. (Block 15
9). The program then continues as shown in this Figure 13C. Upon return from the interrupt (block 164), any disk transfers are processed. If the operator has pressed the start button, a queue request interrupt is received and the request is processed as shown in Figure 13A. The program continues according to block 150 since a repeat restart may be in progress. If so, pattern #1 in relation to Figure 14
The situation in which there is no data to be output from the output buffer to the machine storage 72 has already been described. We will not discuss the situation when pattern #1 is to be printed and therefore there is data to be output in response to a queue request. A pointer is set to point to the accumulation in the output buffer of pattern #1 data into the subgroup of data to be output. This subgroup is located by a column address equal to (column address for subgroup A) + [word count x (gun bar to be output - 1) (block 216). This sets the pattern #1 data. The location of the data in the current column to be sent to the first gun bar that fires the source 80 is then given.
must apply zero to any of the gun bars. sauce 80
The number of gun bars that receive 0 from is (first gun bar to output for pattern #1) - (number of gun bars for printing pattern #2) - 1 (block 218). ). For example, as shown in Figure 9, if pattern #1 uses 8 gun bars, pattern #2 uses 4, and pattern #1 is below gun bars #6-8. Pattern #2 is cancer.
If it is below bars #1-4, the first gun bar to output for pattern #1 is the gun bar.
In bar #6, the number of gun bars printing pattern #2 is four. Therefore, the above equation is 6-4-1,
This means that only one gun bar receives 0 from source 80 at this point. In this example, it is gun bar #5. Continuing with the example above, there is data to be output for pattern #2, and four gun bars #1 to #4 should receive the data, so the program transfers the data from the output buffer to the machine storage. Blocks 140, 142, 14 until sent to 72
4, a data interrupt occurs as each of the four subgroups of data is sent to storage 72. Next, Gun Bar #1
When all ~4 data have been transferred, there is one gun bar that must receive a zero, so the source 80 outputs a zero for one gun bar (block 220) and returns from the interrupt. returns (block 222) and a zero interrupt is generated and processed as described below. With the above example in mind, after source 80 completes outputting zeros (only gun bar #5 receives those zeros at that time), a zero interrupt is generated and the machine returns to complete the last iteration of pattern #1. There is data that must be output to storage 72. Therefore, all cancers
Since there is no zero to the bar and there must be an output of data to gun bars #6 to #8, the program first transfers data for one gun bar (#6 in the example above), Starting with the column address (block 226). A pointer to the output buffer then points to the next subgroup of data to be output for pattern #1 determined by the new column address (block 228). When this data for gun bar #6 is stored in machine storage 72, a data interrupt occurs and the process is stored in machine storage because all data for pattern #1 has not yet been transferred from the output buffer. 72
block 22 until it is filled with suitable data.
6,230 and 228. After processing according to block 228 and after all data for pattern #1 has been transferred to machine storage 72, there is a return from interrupt (blocks 230 or 232, respectively). As another example, if the last repeat of pattern # that uses eight gun bars is below gun bars #7 and #8, and pattern uses only four gun bars #1-#4. The first repetition of #2 is Gun Bar #3~
Assuming it is under #6, two gun bars #5
and #6 must receive 0 from source 80. Therefore, under this condition, source 80 supplies a zero to gun bar #5, and after the zero interrupt occurs, the source is not outputting a zero for all gun bars. Therefore block 2
20, where the source is another gun.
Outputs 0 to bar (#6). Then there is a return from the interrupt (block 22).
2). As already mentioned, the invention can tolerate small gaps (or loss of material) between the two patterns, and this is achieved in the following way. 10th
As shown in block 104 of the diagram, the starting counter is set to 1.
In addition to being set to , a delay counter (not shown) within the computer is set to -1 to indicate that the delay is not progressing during program initiation. As shown in FIG. 13B, the repeat counter is 0 and not all patterns have been completed. That is, if another pattern is to be printed, the delay counter is set to 0, indicating that the delay for the start of the new pattern should be initialized, and the delay length is set to the desired predetermined number of pattern rows. , for example 25 columns i.e. 2.5
Inch equivalent, set equal to. This number means that 25 rows of material are printed on Gun Bar #1 after Gun Bar #1 prints the last row of the last repeat and before it prints the first row of the first repeat of a new pattern. means passing through. Referring now to Figure 13A, after block 148, the delay is in progress since the delay length has been set. If it is not the end of the delay (the delay counter has not reached 25), the delay counter is incremented by one (block 151) and the program bypasses block 150 to avoid processing the start of a new pattern. This continues until the delay counter is advanced to 25, at which point the delay ends. Therefore, the delay counter is set to -1 (block 135) and since the start is now in progress, the start is processed as shown in block 150. As also mentioned above, as soon as the start of a pattern is completed, this pattern is treated as pattern #1 rather than pattern #2. However, there is one exception to this rule, and that is from printing patterns that use more gun bars to printing patterns that use fewer gun bars.
This occurs when switching to printing using a bar. As shown in FIG. 8, the start of the second pattern is completed before the last repetition of the first pattern is completed. The first pattern must continue to be treated as pattern #1 until the last iteration is completed.
Therefore, a delay is added to switch the handling of the second pattern from pattern #2 to pattern #1. This is the 15th
After executing as shown and increasing the number of gun bars to be output for pattern #2 (block 166), the program does not continue with blocks 168 and 170 as it is in stop progress. Returning to 154, the start counter is incremented, thereby delaying treating the second pattern as pattern #1 until the last repeat of the previous pattern has been printed. FIG. 13A shows a block 137 that simulates an interrupt. When the "Output 1 Row" (block 138) routine is in operation, there is a return from the interrupt to output data to each gun bar except gun bar #1. An interrupt is thus simulated to output data to gun bar #1. Thus, to allow processing of the next column while the current column is being output, an interrupt condition is simulated before going to block 138, causing data to be transferred for gun bar #1. As soon as there is a first entry into the column output routine (block) and the output of the current column is started (block 140 or 220 or 226) and a new column address is calculated (block 142 or 228),
Return from interrupt (block 144 or 2)
22 or 146 or 230), the program resumes operation immediately after block 138. Then (until the next queue request is received), the queue output routine operates on real, not simulated, interrupts. FIGS. 17A and 17B respectively show flowcharts for processing the aforementioned start request interrupt and stop request interrupt initialized by the operator. When the operator presses the start button,
The start request flag is set (block 23).
4) indicates that a start is requested and returns from the interrupt (block 23).
6). Similarly, pressing the stop button sets the stop request flag (block 232), indicating that a stop was requested, and returns from the interrupt (block 240).
