Description

The present invention relates to a dyeing apparatus, a dyeing unit, a dyeing / embroidery system, and an adjustment method in the dyeing apparatus.

Commercial automatic embroidery devices have already been commercialized and become widespread, but with conventional automatic embroidery devices, when embroidering multiple colors, embroidery pattern information is created for each color and the needle thread is set to the specified color. Since it needs to be replaced accordingly, a large embroidery device was needed to hold the needle threads of multiple colors. If you try to embroider using a continuous color tone change (gradation) with such a device, you have to prepare the needle thread according to the number of slightly different color tones and embroider while exchanging the needle thread sequentially. Therefore, there was a limitation on the color of the needle thread, which restricted the expressiveness of the embroidery.

Therefore, in recent years, a system has been known in which the needle thread is dyed so as to give a color that changes in the transport direction using inkjet technology, and the dyed needle thread is used in an embroidery machine or a sewing machine to embroider.

Further, in Patent Document 1, in a device having a dyed portion and an embroidered portion, the transport speed of the dyed portion provided on the upstream side of the embroidered portion may be slower than the fluctuating embroidery speed in the embroidered portion. As a countermeasure against this, a technique has been proposed in which a sufficient length of dyed thread is stored in a thread pool and the dyed thread is kept waiting in front of the embroidery portion.

However, in Patent Document 1, the speed difference between the needle thread and the bobbin thread can be eliminated by storing the dyed needle thread in the thread pool in front of the embroidery portion to lengthen the path length, but the needle thread in the embroidery portion Since the position of the color shifts, the color of the needle thread dyed by the color detection part is detected immediately before the embroidery part, and the desired needle thread comes to the proper position of the embroidery pattern. Was wound by a winding device. Therefore, in Patent Document 1, a thread pool and a winding device are required for the alignment of the needle thread, and the device has become complicated and large in size.

Therefore, in view of the above circumstances, the present invention determines the speed difference between the needle thread and the bobbin thread in the embroidery device when a continuous needle thread whose color changes is used in the connected embroidery device without increasing the size of the device. It is possible to provide a dyeing apparatus capable of suppressing the misalignment of the color of the needle thread while eliminating the problem.

In order to solve the above problems, in one aspect of the present invention, the dyeing device is connected to the embroidery device.
A dyeing part that dyes threads based on the dyeing data,
A transport path that changes the path length of the thread from the dyeing section to the embroidery device according to the operation of the embroidery device.
A transport control unit that adjusts the transport speed of the yarn in the transport path according to the change in the path length is provided.
The dyeing section dyes the yarn at a dyeing speed that matches the adjusted transport speed.
Provided is a dyeing apparatus.

According to one aspect, when a continuous thread whose color changes in the connected embroidery device is used in the dyeing device, the speed difference between the needle thread and the bobbin thread in the embroidery device is eliminated without increasing the size of the device. However, the misalignment of the needle thread color can be minimized.

The inlet and outlet of the variable transport path PL are sandwiched by nip rollers 61 and 66 while applying pressure, forming a closed transport path system. The transfer roller 67 is a roller outside the variable transfer path PL.

In the variable transport path PL, the dancer roller 65 provided in the vicinity of the upstream side of the outlet side nip roller 66 can be moved up and down. As the dancer roller 65 moves up and down, the total length of the path length of the variable transport path PL changes.

Further, in the path length variable transport unit 106, a position detection sensor 60 composed of, for example, a linear encoder is provided in the vicinity of the dancer roller 65. The position detection sensor 60 is an example of the position detection means, and by detecting the position of the dancer roller 65, the amount of the path buffer by the dancer roller 65 can be known and the path length can be calculated.

The central nip roller 63 is configured by sandwiching the thread N between the central drive roller 631 and the nip roller 632, and the central motor 69, which is a drive motor, is connected to the central drive roller 631. The central motor 69 drives the drive roller 631 to rotate at a transfer speed instructed by the arithmetic mechanism 108 (see FIG. 5). The inlet side motor 68 and the central motor 69 serve as a driving unit for the path length variable transport unit 106 for transporting the needle thread.

The central drive roller 631 driven by the central motor 69 rotates at a slightly faster speed than the inlet side, and can be conveyed between the inlet side nip roller 61 and the central nip roller 63 without slack.

The outlet-side nip roller 66 is provided in the vicinity of the embroidery device 2 and serves as a downstream end of the variable transport path PL. The outlet side nip roller 66 is composed of two rollers 661 and 662 which are a pair for sandwiching the thread N, and no driving force is applied. Therefore, the outlet-side nip roller 66 carries out the thread N in a form of being pulled by the embroidery device 2 by the amount consumed by the embroidery device 2.

In the variable transport path PL having such a configuration, the dancer roller 65 moves up and down according to the pulling force from the embroidery device 2, so that the cumulative amount of thread consumption of the embroidery device 2 and the thread N transported by the inlet side nip roller 61 are transferred. The difference in the cumulative total of is the change in the path length. As a result, in the transfer from the dyeing unit 103 to the embroidery device 2, changes in the tension of the needle thread such as slackening and dragging of the needle thread immediately before the embroidery device 2 do not accumulate.

In the present invention, on the premise that the path length in the variable transport path PL changes according to the operation of the embroidery device 2, the thread transport speed in the variable transport path PL is adjusted, and the next time in the dyeing device 1. Correct the data length of the staining data of. Therefore, while keeping the tension of the needle thread supplied to the embroidery device 2 side constant by changing the transport path length and adjusting the transport speed, the position of the color boundary in the needle thread is adjusted by adjusting the dyeing data length, and the embroidery device 2 It is possible to suppress the deviation between the embroidery position and the dyeing position in.

Further, the embroidery device 2 includes an embroidery image acquisition unit 24, a calculation mechanism 25, a drive driver 26, a drive motor 27, a needle vertical drive unit 281 and a bobbin thread rotation drive unit 282 as parts related to drive control. , X-axis drive unit 283, Y-axis drive unit 284, and stitch counter 29.

The embroidery image acquisition unit 24 is, for example, a communication unit with an external device, acquires an embroidery image (embroidery file) that is the source of embroidery data, and outputs the embroidery image (embroidery file) to the calculation mechanism 25. Alternatively, the embroidery image acquisition unit 24 may be an operation panel or the like, and in the case of the operation panel, the embroidery image is directly input by the operation of the operator.

The calculation mechanism 25 creates embroidery data based on the embroidery image and outputs the embroidery data to the drive driver 26. Further, the calculation mechanism 25 calculates the thread consumption based on the embroidery data and the progress status (stitch data) of how many stitches have been advanced detected by the stitch counter 29, and outputs the thread consumption to the calculation mechanism 108 of the dyeing apparatus 1. do.

Here, the embroidery image is image data (image information, embroidery design data) that is a manuscript of an embroidery pattern on a cloth. In the present embodiment, the calculation mechanism 25 decomposes the embroidery image into each color (RGB value), and based on the size of the embroidery pattern on the cloth, the color of the thread used and the color of the thread so that the embroidery image can be sewn in a smooth order. The continuous length of each color on the thread is determined, and the embroidery data is created so as to form a stitch on the cloth using the thread of the determined color.

Here, the embroidery data is "data that combines data of coordinates for moving the needle and items to be implemented at those coordinates". Specifically, the matters to be implemented at those coordinates are
(1) Insert the needle into the cloth, entangle it with the bobbin thread, return the needle to the surface of the cloth again, and then move it to the position where the needle should be inserted next.
(2) Ending or interrupting embroidery (including switching to another needle and cutting the thread to move to a distant place where the embroidery is not continuous),
(3) Moving to the initialization position (alignment position),
Etc. are included. Further, as the embroidery data file, formats such as ".dst" and ".pes" are generally known.

The drive driver 26 drives and controls the drive motor 27 based on the embroidery data.

The needle vertical drive unit 281 is a so-called balance, and drives the vertical movement of the needle 21 through which the needle thread N is passed by converting the rotary motion of the upper shaft connected to the drive motor 27 into a vertical motion.

The bobbin rotation drive unit 282 rotates the bobbin thread rotating body 22 in conjunction with the vertical movement of the needle 21 by the rotational movement of the upper shaft and the lower shaft connected via the belt cam crank.

The X-axis drive unit 283 and the Y-axis drive unit 284 are stage movement drive units (cloth feed units), and are interlocked with the vertical movement of the needle 21 and the rotation of the bobbin thread rotating body 12 by the rotational movement of the lower axis. Then, the movement of the stage 23 on which the cloth C is placed is driven in the X direction and the Y direction. At this time, as a method of feeding the cloth C, the entire stage 23 may be moved, or the feed dog provided in the hole formed in the stage 23 may be moved.

The needle up / down drive unit 281, the bobbin thread rotation drive unit 282, the X-axis drive unit 283, and the Y-axis drive unit 284 are drive mechanisms 28 that are driven in conjunction with one drive motor 27. Therefore, the rotation of the drive motor 27 causes the needle 21 to move up and down, the bobbin thread rotating body 22 to rotate, and the cloth C to move XY on the stage 23. For example, one vertical movement of the needle 21 is linked to one or an integral number of rotational movements of the bobbin thread rotating body 22.

The stitch counter 29 is a sensor that detects the vertical movement of the needle 21, and is provided on a needle rod that holds the needle 21, for example, and corresponds to how many times the needle 21 has moved up and down, that is, how many stitches have advanced. Detect the number.

(Dyeing / transport control block)
Here, the details of the control of staining and transport in FIG. 5 will be described with reference to FIG. FIG. 6 is a functional block diagram of a portion related to dyeing / transport control in the first control example of the dyeing / embroidery system 3 of the first embodiment.

The calculation unit 811, the embroidery data length calculation unit 812 for each transport predetermined length, the embroidery data length deviation amount calculation unit 813, and the dyeing data length correction value setting unit 814 function as the dyeing / transport adjustment unit α.

On the other hand, the calculation mechanism 25 of the embroidery device 2 has an embroidery data creation unit 501, a stitch position calculation unit 502, a current embroidery position grasping unit 503, and an assumed thread consumption calculation unit 504 in an executable manner.

In the dyeing data processing unit 107 of the dyeing device 1, the embroidery image acquisition unit 701 communicates with the embroidery device 2 to acquire the embroidery image and the embroidery data.

The dyeing data creation unit 702 creates dyeing data (initial dyeing data) based on the embroidery image and the embroidery data. Specifically, the dyeing data creation unit 702 includes information on the blending amount of each KCMY color used for dyeing to realize the color of the thread and the dyeing continuation length of each color in the ejection head of KCMY, which are included in the embroidery data. Create staining data.

The dyeing data adjusting unit 703 sets a correction value for each detection timing set in the dyeing data length correction value setting unit 814 of the arithmetic mechanism 108 for the data length in the dyeing data (initial dyeing data) created by the dyeing data creation unit 702. Increase or decrease with to create staining data with the next data length corrected. Then, the created dyeing data is output to the dyeing control unit 815 of the arithmetic mechanism 108.

Further, the embroidery data creation unit 501 of the calculation mechanism 25 of the embroidery device 2 creates embroidery data based on the embroidery image which is the acquired image data. The embroidery data is data in which the coordinates for moving the needle and what to do at that position are paired as described above.

The stitch position calculation unit 502 acquires stitch data (number of stitches), which is data of how many stitches are output from the stitch counter 29, that is, which stitch (stitch) is currently being sewn, in real time. Calculate the stitch speed.

The current embroidery position grasping unit 503 is a stitch position calculation unit, and calculates the current embroidery position (stitch position), which is the extent to which the embroidery is recommended from the embroidery data and the stitch data.

At the start of embroidery, the estimated thread consumption calculation unit 504 predicts the thread consumption rate (estimated thread consumption) in the embroidery device 2 based on the embroidery data.

Here, in the dyeing apparatus 1 of the first control example of the present invention, the position detection by the position detection sensor 60 and the adjustment of the data length of the next dyeing data based on the position detection are performed for each predetermined transport length of the thread. Will be executed. The predetermined transport length (predetermined length) of the thread, which is the reference for executing the path length detection, is divided into a number according to the total data length of the dyeing data (initial dyeing data) created by the dyeing data creation unit 702. The divided data length (reference staining data length) is set by the predetermined length setting unit 801 of the calculation mechanism 108 so that the divided data length (reference staining data length) can be appropriately adjusted. Alternatively, the reference predetermined length may be set to a length predetermined by the apparatus.

The transport amount predetermined length counting unit 802 counts the transport amount of the needle thread to be conveyed by the rotary encoder 613 provided on the inlet side nip roller 61 when the needle thread is conveyed at the set transfer speed. In the transport amount predetermined length counting unit 802, the transport amount of the counted needle thread reaches the predetermined length set by the predetermined length setting unit 801 and the transport amount of the yarn by the inlet side nip roller 61 reaches the predetermined length. Each time, the position detection sensor 60 is notified as the detection timing.

The position detection sensor 60 detects the vertical position of the dancer roller 65 for each predetermined transfer length of the yarn notified by the transfer amount predetermined length counting unit 802.

The path length calculation unit 803 of the calculation mechanism 108 adds the vertical position of the dancer roller 65 detected by the position detection sensor 60 and the path lengths of other parts of the variable transport path PL to obtain the path length of the variable transport path PL. Calculate the total length.

The initial path length storage unit 804 stores the path length of the variable transport path PL immediately before the start of staining as the initial path length. The path length deviation amount calculation unit 805 calculates the deviation amount of the detected path length of the variable transport path PL from the initial path length at the predetermined length transport timing of the yarn this time.

The previous path length storage unit 806 stores the path length of the detected variable transport path PL at the predetermined length transport timing (detection timing) of the current thread, and the path length is the previous one at the next detection timing. It is referred to as the path length.

The path length change amount calculation unit 807 calculates the path length of the variable transport path PL detected at the current detection timing, which is different from the path length of the variable transport path PL detected at the previous detection timing, from the previous time. Calculated as the amount of change in path length.

The predetermined length transport time calculation unit 810 calculates the transport time for transporting the yarn by a predetermined length. At the initial detection timing, the transport speed is an initial value, so the predetermined length transport time is a specified value. From the second time onward, in the previous (n-1) detection timing, the correction was made based on the next (n) transfer speed adjusted by the transfer control unit 809, which corresponds to the interval between the current and previous detection timings. Calculate the time required to feed the needle thread to the specified length at the transport speed (hereinafter referred to as the adjusted transport time).

The estimated thread consumption calculation unit 811 for each predetermined length is a thread consumption calculation unit that calculates and calls the estimated thread consumption used by the embroidery device during the detection timing. Specifically, the estimated thread consumption calculation unit 811 for each predetermined length calculates the predetermined length transfer time at the current detection timing among the estimated thread consumption calculated by the estimated thread consumption calculation unit 504 of the embroidery device 2. The estimated needle thread consumption (estimated thread consumption on the embroidery device 2 side while feeding a predetermined length) is calculated by the transfer time (adjusted transfer time) required for the next transfer period calculated by the unit 810. Further, the needle thread consumption amount calculated at the previous detection timing and assumed in the current transport period (adjusted transport time) is called at the current detection timing and output to the transport speed correction value calculation unit 808.

The transport speed correction value calculation unit 808 is assumed by the amount of deviation from the initial path length, the amount of change from the previous path length, and the current adjustment transport time calculated by the assumed thread consumption calculation unit 811 for each predetermined length. Based on the needle thread consumption (estimated thread consumption between the previous and current detection timings), the correction value for the future needle thread transfer speed is calculated. In this way, the transport speed of the needle thread is corrected to adjust the transport time (adjustment transport time) for feeding the predetermined length of the needle thread.

The transfer control unit 809 sets the transfer speed of the needle thread so as to reflect the correction value set by the transfer speed correction value calculation unit 808 after the first detection timing during dyeing. Further, at the start of dyeing, the transfer control unit 809 calls the estimated consumption amount predicted from the embroidery data in the embroidery device 2, and sets the transfer speed (initial value) so that the transfer amount corresponds to the estimated consumption amount. Set. Then, the transport control unit 809 drives and controls the inlet side motor 68 and the central motor 69 at the set transport speed (initial value or corrected transport speed). The transfer speed correction value calculation unit 808 and the transfer control unit 809 function as the transfer speed control unit.

Further, the information on the transfer speed by the transfer control unit 809 is also notified to the dyeing control unit 815 together with the signal information of the rotary encoder 613. The dyeing control unit 815 discharges the liquid for dyeing to the discharge heads 30Y to 30K according to the transport speed, that is, the dyeing unit 103 is made to discharge the needle yarn at a dyeing speed that matches the adjusted transport speed. The discharge head control unit 816 and the head driver 39 are controlled so as to be dyed.

The embroidery data length calculation unit 812 for each predetermined transfer length calls the stitch position of the current embroidery position grasping unit 503 of the embroidery device 2 at the current detection timing, and during the current transfer period (between the previous and current detection timings). The embroidery data length used in the embroidery device 2 is calculated. The embroidery data length used is also called the embroidery data consumption amount and indicates the progress of the embroidery data.

The embroidery data length deviation amount calculation unit 813 has the embroidery data length used in the current transport period calculated by the embroidery data length calculation unit 812 for each transport predetermined length, and the estimated thread consumption calculation unit 504 of the embroidery device 2. The amount of deviation of the embroidery data length is calculated by comparing with the embroidery data length assumed in this transportation period.

The dyeing data length correction value setting unit 814 is calculated by the estimated thread consumption calculation unit 811 for each predetermined length, and the needle thread consumption amount estimated during the called current adjustment transfer time (between this time and the next detection timing). The next dyeing data length correction value is set based on the estimated thread consumption used in (1) and the deviation amount of the embroidery data length calculated by the embroidery data length deviation amount calculation unit 813. Further, in the dyeing data length correction value setting unit 814, as an adjustment of the data length of the dyeing data used in the transport period until the next detection timing, the first part of the dyeing data length corresponding to the predetermined length of the next yarn is used. Is set to be corrected for increase / decrease. The method of correcting the data length of the staining data will be described in detail together with FIG.

The dyeing data adjusting unit 703 increases or decreases the dyeing data length corresponding to the predetermined length with the correction value set by the dyeing data length correction value setting unit 814, creates the dyeing data in which the data length is corrected, and controls the dyeing. Output to unit 815.

The dyeing control unit 815 receives the corrected dyeing data from the dyeing data adjusting unit 703, generates discharge data for each color corresponding to the discharge heads 30Y to 30K based on the dyeing data, and responds to the transport speed. Adjust the discharge timing.

The head control unit 816 outputs the discharge data for each color generated by the dyeing control unit 815 at the adjusted discharge timing, and drives and controls the head driver 39.

The head driver 39 drives the ejection heads 30K to 30Y so as to eject ink from the nozzles 31 of the ejection heads 30K to 30Y to the thread N being conveyed at a timing corresponding to the conveying speed.

(flowchart)
First, with reference to FIG. 7, the entire flow during dyeing in the dyeing apparatus 1 of the present invention will be described. FIG. 7 is an overall flow chart of dyeing in the present invention.

In step S11, the dyeing device 1 acquires the embroidery image and the embroidery data from the embroidery device 2.

In step S12, the dyeing data processing unit 107 creates dyeing data (initial dyeing data) based on the embroidery image and the embroidery data.

In step S13, in the first control example, the arithmetic mechanism 108 sets a predetermined length (specified length) for dividing the staining data for adjustment. This predetermined length is used in the first control example to specify the timing of position detection and data adjustment.

In step S14, the dyeing device 1 acquires the estimated thread consumption from the embroidery device 2.

In S15, the calculation mechanism 108 sets the initial value of the transport speed based on the assumed yarn consumption.

Further, in step S16, the position detection sensor 60 detects the position of the dancer roller 65, and the arithmetic mechanism 108 calculates the path length of the variable transport path PL based on the position and uses that value as the initial value of the path length. Remember as.

Note that FIG. 7 shows an example in which the detection and calculation of the initial value of the path length of S16 is performed after S12 to S15, but the detection and calculation of the initial value of the path length of S16 is carried out from S12 to S15. It may be carried out in parallel with, or it may be carried out before S12 to S15.

In step S17, the yarn transfer is started at the initial value of the transfer speed set in S15, and the dyeing operation based on the dyeing data and the embroidery operation based on the embroidery data are started.

In step S18, control during the dyeing operation is performed. The control during the dyeing operation will be described in detail with reference to FIGS. 8, 11 and 13.

In step S19, all the dyeing data is completed, and the dyeing and transporting operations and the embroidery operation in the dyeing apparatus 1 are completed.

Here, the details of the control during the dyeing operation in the first control example will be described with reference to FIGS. 8, 9, and 10. FIG. 8 is a detailed flowchart relating to the control during the dyeing operation in the first control example of the present invention. This flowchart is a detailed flowchart of step S18 in FIG. FIG. 9 is a table showing a specific example of control according to the flow of FIG. The numerical values in parentheses in the flow of FIG. 8 correspond to the lines of FIG. FIG. 10 is a diagram showing an example of adjusting the staining data.

In step S701 of FIG. 8, when the needle thread is conveyed by a predetermined length (specified length) from the time when the transfer is started by the start of dyeing of S17, it is assumed that the current detection timing has been reached, and the process proceeds to S702.

In step S702, the transport path length at the current detection timing is calculated. Specifically, the position detection sensor 60 detects the position of the dancer roller 65 to calculate the path length of the variable transport path PL at the current detection timing.

In step S703, it is determined whether or not the transport path length calculated in S702 is the same as the initial value set in S16 of FIG. In the same case (YES in S703), the transport path length this time proceeds to S707 assuming that there is no deviation from the initial value.

If the current transport path length is different from the initial value (NO in S703), it is assumed that the current transport path length deviates from the initial value in step S704, and the amount of deviation from the initial value of the current transport path length is calculated. After the calculation, the process proceeds to S707.

In the numerical value of the deviation amount of the path length shown in the sixth row of FIG. 9, a negative value means that the position of the dancer roller 65 detected by the position detection sensor 60 has moved upward from the initial value, and is positive. The value of means that the position of the dancer roller 65 detected by the position detection sensor 60 has moved downward from the initial value.

In step S705, it is determined whether or not the transport path length calculated in S702 is the same as the transport path length calculated at the previous detection timing. At the first detection timing, the path length calculated at the previous detection timing, which is the comparison target, is the initial value of the transport path length, and at the second and subsequent detection timings, the comparison target is the previous detection timing. It is the calculated path length. If the current path length is the same as the previous time (YES in S705), the process proceeds to S707 assuming that the current transport path length has not changed from the previous time.

If the current transport path length is different from the previous transport path length (NO in S705), it is assumed that the current transport path length has changed from the previous time in step S706, and the current transport path length is changed from the previous transport path length. After calculating the amount of change in, the process proceeds to S707.

In the numerical value of the amount of change in the path length shown in the 7th row of FIG. 9, a negative value means that the position of the dancer roller 65 detected by the position detection sensor 60 has moved upward from the previous time, and is positive. The value means that the position of the dancer roller 65 detected by the position detection sensor 60 has moved downward from the previous time.

In step S707, the needle thread length consumed by the embroidery apparatus 2 in the current transport period, which is transported at the initial transfer speed at the first detection timing, triggered by the receipt of the deviation amount and the change amount of the transfer path length. Calculate the needle thread consumption. At the second and subsequent detection timings, the needle thread consumption amount calculated by the calculation of the previous detection timing and assumed by the embroidery device in the next transfer period is called (see step S709). Then, the calculated or called needle thread length consumed by the embroidery device in the current transport period is sent to the transport speed correction value calculation unit 808.

Note that FIG. 9 shows an example in which the calculation or calling of the needle thread consumption amount in the current transport period of S707 is performed after S702 to S706, but the calculation or calling of the needle thread consumption amount of S707 is performed. , S701 may be carried out in parallel with S702 to S706, or may be carried out before S702 to S706, triggered by the transfer of the needle thread to a predetermined length in S701.

In step S708, the transport speed correction value calculation unit 808 calculated the deviation amount from the initial value of the current transport path length calculated in S704, the change amount of the current transport path length calculated in S706 from the previous time, and S707. The time required to feed the needle thread to the specified length by correcting the thread transfer speed at the specified length until the next detection timing according to the upper thread length consumed by the embroidery device 2 during the current transfer period. To adjust.

Here, the calculation of the correction value of the yarn transport speed in S708 will be described using the table of FIG. 9 as an example. In this control example, since the calculation for correction is performed every time the yarn is conveyed by a predetermined length, the yarn transport length until the next detection is always constant. In FIG. 9, the predetermined yarn transport length is shown in the first line as a reference value “10”, and the reference value 10 will be described below as an example.

The thread transport speed correction value calculated in S708 is shown in the numerical value in the fifth row of the table of FIG. 9, and can be expressed by the following formula.
Thread transfer speed time correction value = [A] + [B]
[A] = Time required to send a predetermined length (set value) ÷ (upper thread consumption of embroidery machine (corrected predicted value) + amount of change in path length from the previous time) x amount of change in path length from the previous time [B] = Time required to send a predetermined length (set value) ÷ (upper thread consumption of embroidery machine (predicted value after correction) + amount of change in path length from the previous time) x deviation from the initial value of the path length amount

Further, the amount of deviation from the initial value of the current transport path length calculated in S704 used for calculating the thread transport speed correction value corresponds to the numerical value in the sixth row of the table in FIG. 9, and the current transport in S706. The amount of change in the path length from the previous time corresponds to the numerical value in the 7th row of the table in FIG. 9, and the thread length consumed by the embroidery device during the current transport period calculated in S707 is the 10th row in the table in FIG. It corresponds to the numerical value of the eye.

Therefore, the transfer speed correction value (upper thread transfer time correction value) set after each detection timing, which is shown in the fifth line of FIG. 9, is
[(Next value on the 2nd line) / {(Current value on the 10th line) + (Current value on the 6th line)} x (Current value on the 6th line)] +
It is calculated by [(next value on the 2nd line) / {(current value on the 10th line) + (current value on the 6th line)} × (current value on the 7th line)].

When the numerical value of the thread transport speed correction value in FIG. 9 is applied to the above formula and examined,
The transport speed correction value set after the first detection is [12 / {10+ (-0.2)} x (-0.2)] + [12 / {10+ (-0.2)} x (-0.2)] = -0.489996.
The transport speed correction value set after the second detection is [8 / {9 + 0.1} x 0.1] + [8 / {9 + 0.1} x (-0.1)] = 0. Will be.
The transport speed correction value set after the third detection is [10 / {10 + 0.2} × (0.2)] + [10 / {10 + 0.2} × 0.1] = 0. It becomes 2941176.
The transport speed correction value set after the fourth detection is [8 / {10.5 + (-0.1)} x (-0.1)] + [8 / {10.5 + (-0. 1)} × 0] = −0.076923.
The transport speed correction value set after the fifth detection is [12 / {9.7 + 0.1} × (0.1)] + [12 / {9.7 + 0.1} × 0.1. ] = 0.244898.

Returning to FIG. 8, in step S709, the estimated thread consumption calculation unit 811 for each predetermined length is assumed by the embroidery device 2 in the next transfer period in the time required to feed the needle thread to the specified length at the corrected transfer speed. Calculate the needle thread consumption. That is, the assumed yarn consumption calculation unit 811 for each predetermined length has a predetermined length, a time corresponding to the transport speed, and a transfer speed between the current time and the next detection timing for transporting the yarn at the transport speed adjusted for the next time. , Calculate the estimated thread consumption used in the embroidery device 2.

In step S710, it is determined whether or not the needle thread consumption assumed by the embroidery apparatus in the next transport period is the same as the predetermined length of the needle thread, that is, the predetermined dyeing data length. In the same case (YES in S710), it is assumed that the needle thread consumption assumed by the embroidery device in the next transport period is the same as the specified length of the needle thread, and the process proceeds to S715.

If the adjusted needle thread transfer amount is different from the specified needle thread length (NO in S710), the process proceeds to step S711, and the difference between the needle thread consumption amount assumed by the embroidery device and the specified length of the needle thread in the next transfer period. Is calculated, and the process proceeds to S715.

Further, in step S712, in parallel with S708 to S711, the embroidery data is consumed by the embroidery device 2 during the current transport period (the period during which the transport time corresponding to the corrected transport speed has elapsed) between the current and previous detection timings. Calculate the amount. Specifically, the embroidery data length calculation unit 812 for each predetermined length of transport calls the stitch position of the current embroidery position grasping unit 503 of the embroidery device 2 at the detection timing, and the embroidery data used indicating the progress of the embroidery data. Calculate the length (embroidery data consumption).

In step S713, it is determined whether the embroidery data length consumed in the current transport period calculated in S712 is the same as the assumed embroidery data length, that is, whether the embroidery position is as expected. If it is as expected, the embroidery data length consumed by the embroidery device during this transport period is assumed to be as expected, and the process proceeds to S715.

In step S714, the embroidery data length deviation amount calculation unit 813 has the thread consumption amount (embroidery data length) assumed by the embroidery device 2 of the embroidery data length consumed in the current transport period between the previous detection timing and the current detection timing. Calculate the amount of deviation from. The deviation amount of the embroidery data length used calculated in S714 is shown in the 11th line of FIG. 9, and the deviation amount at the initial timing is “−0.1”.

In step S715, according to the difference between the needle thread consumption amount estimated by the embroidery device and the specified length of the needle thread in the next transport period calculated in S711, and the deviation amount from the assumption of the embroidery data length calculated in S714. Then, the dyeing data correction value in the next transport period is calculated.

The correction value of the staining data length calculated in S715 is shown in the numerical value in the 8th row of the table of FIG. 9, and can be expressed by the following formula.
Dyeing data length correction value = {(specified length)-(thread consumption estimated in the next adjustment transfer time)}-(deviation in the consumed embroidery data length)

Further, the difference between the needle thread consumption amount assumed by the embroidery device in the next transport period calculated in S711 and the specified length of the needle thread used in the calculation of S715 is {(next time in the first row) in the table of FIG. Numerical value)-(next numerical value in the 10th row)}, the amount of deviation from the assumed embroidery data length consumed calculated in S714 corresponds to the current numerical value in the 11th row of the table in FIG. ing.

Therefore, the staining data correction value set after each detection timing shown in the 8th row of FIG. 9 is {(next numerical value in the 1st row)-(next numerical value in the 10th row)}-(11) in the table. It is calculated by the current numerical value of the line).

In FIG. 9, when the staining data correction value is calculated by applying the above formula,
The staining data correction value set after the first detection is (10-9)-(-0.1) = 1.1.
The staining data correction value set after the second detection is (10-10) -0 = 0.
The staining data correction value set after the third detection is (10-10.5) -0 = -0.5.
The staining data correction value set after the fourth detection is (10-9.7) -0.2 = 0.1.
The staining data correction value set after the fifth detection is (10-10.1) -0 = -0.1.

Note that FIG. 9 shows the detection and correction for 6 times, but in the subsequent control as well, the next time as appropriate is used by using the path length and the thread consumption estimated in the adjusted transfer time at each detection timing. Correct the transport speed. Then, the dyeing data length is appropriately corrected according to the amount of thread consumption expected in the next adjusted transport time using the transport speed and the deviation amount of the embroidery data length consumed this time.

Returning to FIG. 8, in step S716, the correction of the dyeing data in the next transport period is reflected according to the dyeing data correction value. Specifically, depending on the staining data correction value, the first data of the staining data in the next transport period is deleted, or dummy data is added immediately before the staining data.

Here, a method of adjusting the staining data length will be described with reference to FIG. 10. In FIG. 10, (a) shows a case where the next assumed upper thread consumption is longer than the upper thread transfer specified length, and (b) shows the case where the next assumed upper thread consumption is longer than the upper thread transfer specified length. Also shows a short case. The next estimated yarn consumption amount means the estimated yarn length consumed by the embroidery apparatus 2 in the time (adjusted transport time) required to feed the needle yarn to the specified length at the corrected transport speed next time. Further, FIG. 10 shows a case where there is no deviation in the embroidery data length used at the current detection timing.

Here, since the dyeing unit 103 performs dyeing according to the transport speed, the specified length of the needle thread = the reference dyeing data length.

As shown in FIG. 10A, when the next assumed yarn consumption amount is shorter than the needle yarn transport specified length, dyeing data is added in the next transport period. Specifically, dummy data is added to the beginning of the dyeing data in the next transport period in which the needle thread is transported by the specified length at the adjusted transport speed. The dummy data is data of the same color as the first color of the next data.

On the other hand, as shown in FIG. 10B, when the next assumed yarn consumption is longer than the needle yarn transport specified length, the dyeing data length is reduced in the next transport period. Specifically, the first data of the dyeing data is deleted in the next transport period in which the needle thread is transported by the specified length at the adjusted transport speed.

It should be noted that such correction of the dyeing data length is performed when the same color continues for a certain length or longer (for example, the needle thread transport specified length or longer), rather than the dyeing in which a plurality of colors are frequently switched for each short length. It is effective for.

Returning to FIG. 8, in step S717, in the next transport period, the transport at the adjusted transport speed, the dyeing at the dyeing speed according to the adjusted transport speed, and the embroidery data based on the corrected dyeing data. Perform embroidery based on. At this time, as necessary, as a reflection of the control, the dyeing data is conveyed to the inlet-side nip roller 61 during transfer by reflecting the increase / decrease adjustment of the transfer speed, and the data length is adjusted in the dyeing unit 103. The dyeing operation is performed based on the above.

Then, in step S718, when the needle thread is conveyed to a specified length, that is, when the amount conveyed by the inlet-side nip roller 61 reaches the next predetermined length, it is assumed that the next detection timing has been reached, and the process returns to the front of S702. S702 to S717 are carried out in the same manner as in the transport period of the above, the transport speed is adjusted, and the staining data is corrected to reflect it. Then, the dyeing operation, the transport operation, and the embroidery operation according to the dyeing data or the adjusted dyeing data are executed until the dyeing data is completed in step S719.

When all the dyeing data is completed in step S719, the process returns to S19 in FIG. 7, and the dyeing / transporting operation in the dyeing apparatus 1 and the embroidery operation in the embroidery apparatus 2 are terminated.

As described above, in the dyeing apparatus in this control example, the transfer speed of the needle thread is adjusted by using the transfer of the needle thread to the specified length as a trigger, thereby eliminating the speed difference between the needle thread and the bobbin thread in the embroidery device. It is possible to suppress color misalignment. Furthermore, in consideration of the adjusted transport speed, the dyeing data length is adjusted for each predetermined length transport according to the expected thread consumption for the next time and the amount of deviation from the assumed embroidery data length for embroidery. While it is not conspicuous, the lack of staining data is replenished and corrected, and the surplus data is truncated and corrected. This makes it possible to minimize the amount of thread color deviation in the embroidery device without causing a cumulative error between the thread consumption on the embroidery device side and the thread dyeing length.

(Second control example)
FIG. 11 is a detailed flowchart relating to the control during the dyeing operation in the second control example of the present invention. In the above first control example, the dyeing data length is corrected by using the deviation amount from the needle thread transport specified length of the next assumed thread consumption amount and the deviation of the embroidery data length. The cumulative value is used in setting the correction value for the staining data length. Hereinafter, only the differences from FIG. 8 will be described.

In this control example, in step S809, the estimated thread consumption calculation unit 811 for each predetermined length is assumed by the embroidery device by the next transfer period in the time required to feed the needle thread to the specified length at the corrected transfer speed. Calculate the cumulative needle thread consumption. Specifically, the estimated yarn consumption calculation unit 811 for each predetermined length has the predetermined length, the time corresponding to the transport speed, and the current and next detection timings for transporting the yarn at the transport speed adjusted for the next time. The estimated cumulative thread consumption used by the embroidery device during the period is added to the cumulative thread consumption up to this time, and the estimated cumulative thread consumption until the next detection timing is calculated.

In step S810, it is determined whether or not the cumulative needle thread consumption assumed by the embroidery apparatus by the next transfer period is the same as the cumulative needle thread length, that is, the cumulative predetermined dyeing data length. In the same case (YES in S810), it is assumed that the cumulative needle thread consumption assumed by the embroidery device 2 by the next transport period is the same as the specified length of the accumulated needle thread, and the process proceeds to S815.

If the cumulative needle thread transfer amount up to the next time is different from the specified length of the needle thread accumulated up to the next time (NO in S810), the process proceeds to step S811, and the cumulative amount assumed by the embroidery device 2 until the next transfer period is reached. The difference between the needle thread consumption and the cumulative needle thread specified length up to the next time is calculated, and the process proceeds to S815.

In step S815, the difference between the needle thread consumption amount assumed by the embroidery device 2 and the specified length of the needle thread in the next transport period calculated in S811 and the deviation amount from the assumption of the embroidery data length calculated in S814 Accordingly, the staining data correction value in the next transport period is calculated. The subsequent flow is the same as that of the first control example.

As described above, in the dyeing apparatus in this control example, the transfer speed of the needle thread is adjusted by using the transfer of the needle thread to the specified length as a trigger, thereby eliminating the speed difference between the needle thread and the bobbin thread in the embroidery device. It is possible to suppress color misalignment. Furthermore, in consideration of the adjusted transport speed, the dyeing data length can be adjusted for each predetermined length transport according to the cumulative estimated thread consumption until the next time and the amount of deviation from the assumed embroidery data length. , While it is not noticeable as embroidery, the missing part of the dyeing data is replenished and corrected, and the surplus data is cut off and corrected. This makes it possible to minimize the amount of thread color deviation in the embroidery device without causing a cumulative error between the thread consumption on the embroidery device side and the thread dyeing length.

(Third control example)
FIG. 12 is a functional block diagram of a portion related to the control of the dyeing / embroidery system of the third control example of the first embodiment. In the first control example and the second control example, the detection timing is that the needle thread is conveyed by a specified length, but in the third control example, the subsequent control is performed with the lapse of a specified time as the detection timing. Only the differences from FIG. 6 will be described below.

Further, the calculation mechanism 108β of the second control example includes a specified time setting unit 817, a specified time counting unit 818, a path length calculation unit 803, an initial path length storage unit 804, a path length deviation amount calculation unit 805, and a previous path length storage unit. 806, path length change amount calculation unit 807, transport speed correction value calculation unit 808β, transport control unit 809β, thread transport amount calculation unit 819 for each specified time, estimated thread consumption calculation unit 820 for each specified time, embroidery data length for each specified time It has a calculation unit 821, an embroidery data length deviation amount calculation unit 813β, a dyeing data length correction value setting unit 814β, a dyeing control unit 815, and a discharge head control unit 816.

Staining data adjustment unit 703 of the staining data processing unit 107, specified time setting unit 817, specified time counting unit 818, path length calculation unit 803, initial path length storage unit 804, path length deviation amount calculation unit 805 of the calculation mechanism 108β. , Previous path length storage unit 806, path length change amount calculation unit 807, transport speed correction value calculation unit 808β, transport control unit 809β, specified time per thread transport amount calculation unit 819, specified time per estimated thread consumption calculation unit 820, The embroidery data length calculation unit 821, the embroidery data length deviation amount calculation unit 813β, and the dyeing data length correction value setting unit 814β function as the dyeing / transport adjustment unit β.

In the dyeing apparatus 1 of the third control example of the present invention, the position detection by the position detection sensor 60 and the adjustment of the data length of the next dyeing data based on the detection are executed at predetermined time intervals. The specified time, which is the reference for executing the path length detection, is set by the specified time setting unit 817 of the arithmetic mechanism 108β. Alternatively, the reference specified time may be set to a time specified in advance by the apparatus.

The specified time counting unit 818 counts the time from the time of the start of transportation or the time of the previous detection timing. When the counted time reaches the specified time (predetermined time), the specified time counting unit 818 notifies the position detection sensor 60 as the detection timing each time the specified time is reached.

The position detection sensor 60 detects the vertical position of the dancer roller 65 at predetermined time intervals. Using the detection result, the path length calculation unit 803, the initial path length storage unit 804, the path length deviation amount calculation unit 805, the previous path length storage unit 806, and the path length change amount calculation unit 807 are carried every specified time. The path length is calculated, and the amount of deviation from the initial value of the transport path length for each specified time and the amount of change in the transport path length for each specified time from the previous time are calculated.

The yarn transfer amount calculation unit 819 for each specified time calculates the yarn transfer amount in the specified time, which is the current transfer period. At the initial detection timing, the transfer speed is the initial value, so the thread transfer amount for each specified time becomes the specified value. From the second time onward, the needle thread is corrected at the current transport period based on the next (n) transport speed adjusted by the transport control unit 809β at the previous (n-1) detection timing. Calculate the transport amount (transport length) when the product is transported for the specified time.

The estimated thread consumption calculation unit 820 for each specified time is the estimated thread consumption calculation unit 819 for each specified time at the detection timing of the estimated thread consumption calculated by the estimated thread consumption calculation unit 504 of the embroidery device 2. The estimated needle thread consumption (estimated thread consumption on the embroidery device 2 side while feeding the thread for a specified time) corresponding to the calculated transport amount is calculated. Further, the needle thread consumption amount calculated at the previous detection timing and assumed in the current transport period (specified time) is called at the current detection timing and output to the transport speed correction value calculation unit 808β.

The transport speed correction value calculation unit 808β is assumed by the amount of deviation from the initial path length, the amount of change from the previous path length, and the current specified time calculated by the estimated thread consumption calculation unit 820 for each specified time. Based on the amount of yarn consumed, the correction value for the transport speed of the needle yarn in the future is calculated. As described above, in this control example, the transport length of the yarn transported in the specified time is adjusted by correcting the transport speed of the needle thread.

During dyeing, the transfer control unit 809β sets the transfer speed of the needle thread so as to reflect the correction value set by the transfer speed correction value calculation unit 808β after the first detection timing.

The embroidery data length calculation unit 821 for each specified time calls the stitch position of the current embroidery position grasping unit 503 of the embroidery device 2 at the current detection timing, and calculates the embroidery data length used in the transport period which is the specified time this time. calculate.

The embroidery data length deviation amount calculation unit 813β is the embroidery data length used in the current transport period calculated by the embroidery data length calculation unit 821 every specified time, and the estimated thread consumption calculation unit 504 of the embroidery device 2 this time. The amount of deviation of the embroidery data length is calculated by comparing with the embroidery data length (current embroidery position) assumed in the transport period of.

The dyeing data length correction value setting unit 814 transports the yarn having a length corresponding to the transport speed for the specified time at the transport speed adjusted for the next time calculated by the assumed yarn consumption calculation unit 820 every specified time. The next dyeing data length correction is based on the assumed thread consumption used by the embroidery device 2 and the amount of deviation of the embroidery data calculated by the embroidery data length deviation amount calculation unit 813β between this time and the next detection timing. Set the value.

Then, the staining data adjusting unit 703 increases or decreases the staining data length corresponding to the specified time with the correction value set by the staining data length correction value setting unit 814β, creates the staining data in which the data length is corrected, and stains. Output to the control unit 815. Then, the head control unit 816 and the head driver 39 use the corrected dyeing data to cause the discharge heads 30K to 30Y to dye the yarn at a dyeing speed that matches the transport speed adjusted at predetermined time intervals.

Here, the details of the control during the dyeing operation in the third control example will be described with reference to FIGS. 13 and 14. FIG. 13 is a detailed flowchart relating to the control during the dyeing operation in the third control example of the present invention. This flowchart is a detailed flowchart of step S18 in FIG. FIG. 14 is a table showing a specific example of control along the flow of FIG. 13. The numerical values in parentheses in each step of the flow of FIG. 13 correspond to the lines of FIG.

In the third control example, since the position of the dancer roller 65 is detected and the path length is calculated at the timing when the specified time elapses, the method of calculating the transport speed and the staining data using the path length is different from the flow of FIG. .. Further, in the overall flow to which the detailed flow of FIG. 13 is applied, a specified time is set in S13 instead of the predetermined length setting of S13 in FIG. 7 as a preparation before the dyeing operation.

In step S901 of FIG. 13, from the time of the start of transport due to the start of dyeing of S17, after transporting for a specified time, it is assumed that the current detection timing has been reached, and the process proceeds to S902.

In steps S902 to S906, similarly to FIG. 8, the transport path length, the amount of deviation from the initial value of the transport path length, and the amount of change of the transport path length from the previous time are calculated.

In step S907, with the receipt of the deviation amount and the change amount of the transport path length as a trigger, at the first detection timing, the needle thread length consumed by the embroidery apparatus 2 in the current transport period transported at the initial transport speed. Calculate the value. In the second and subsequent detection timings, the needle thread consumption estimated by the embroidery device is called for the transport length corresponding to the next transport period calculated at the time of the calculation of the previous detection timing (step). See S909). Then, the calculated or called needle thread length consumed by the embroidery device in the current transport period is sent to the transport speed correction value calculation unit 808β.

In step S908, the transport speed correction value calculation unit 808β determines the amount of deviation from the initial value of the current transport path length calculated in S904, the amount of change in the current transport path length calculated in S906 from the previous time, and in S907. By correcting the thread transfer speed in the next specified time according to the calculated upper thread length consumed by the embroidery device 2 during the current transfer period, the transfer length of the needle thread transported in the specified time) is adjusted. ..

Here, in this control example, the correction value of the transport length of the needle thread to be conveyed in the specified time is calculated by the following formula.
(Thread transport length correction value) = (Amount of deviation from the initial value of the path length) + (Amount of change of the path length from the previous time)

Further, the amount of deviation from the initial value of the current transport path length calculated in S904 used for the calculation in S908 corresponds to the numerical value in the sixth row of the table in FIG. 14, and the previous transport path length in S906 is the previous value. The amount of change from is corresponding to the numerical value in the 7th row of the table of FIG.

Therefore, the thread transport length correction value set after each detection timing shown in the 5th line in FIG. 14 is calculated by {(the current value in the 6th line) + (the current value in the 7th line)}. ..

When the numerical value of the thread transport length correction value shown in the fifth row of the table of FIG. 14 is applied to the above formula and examined, it is examined.
The thread transport length correction value set after the first detection is (-0.2) + (-0.2) = -0.4,
The thread transport length correction value set after the second detection is (-0.1) +0.1 = 0,
The thread transport length correction value set after the third detection is 0.1 + 0.2 = 0.3,
The thread transport length correction value set after the fourth detection is 0+ (-0.1) =-0.1,
The thread transport length correction value set after the fifth detection is 0.1 + 0.1 = 0.2.

Returning to FIG. 13, in step S909, the assumed thread consumption calculation unit 820 for each specified time feeds the needle thread for the specified time and the corrected transfer length at the corrected transfer speed, and the embroidery device in the next transfer period. Calculate the expected needle thread consumption (adjusted needle thread transfer amount) in.

In step S910, it is determined whether or not the needle thread consumption assumed by the embroidery device in the next transfer period is the same as the corrected thread transfer length. In the same case (YES in S910), it is assumed that the needle thread consumption assumed by the embroidery device in the next transport period is the same as the corrected feed thread transfer length, and the process proceeds to S915.

If the adjusted needle thread transfer amount is different from the corrected needle thread transfer length (NO in S910), the process proceeds to step S911, and the needle thread consumption amount assumed by the embroidery device in the next transfer period is corrected. After calculating the difference from the feed length of the needle thread, the process proceeds to S915.

Further, in step S912, in parallel with S908 to S911, the embroidery data consumption amount in the embroidery apparatus 2 at the specified time between the current detection timing and the previous detection timing is calculated.

In step S913, it is determined whether the embroidery data length consumed in the current transport period calculated in S912 is the same as the assumed embroidery data length (10th line in FIG. 14), that is, whether the embroidery position is as expected. .. If it is as expected, the embroidery data length consumed by the embroidery device during this transport period is assumed to be as expected, and the process proceeds to S915.

In step S914, the embroidery data length deviation amount calculation unit 813β calculates the deviation amount of the embroidery data length consumed in the current transport period from the thread consumption amount (embroidery data length) assumed by the embroidery apparatus 2. The deviation amount of the embroidery data length used calculated in S914 is shown in the 11th line of FIG. 14, and the deviation amount at the initial timing is “−0.1”.

In step S915, the dyeing data length correction value setting unit 814β has the difference between the needle thread consumption assumed by the embroidery device 2 in the next transport period calculated in S911 and the corrected feed thread length, and S914. The dyeing data correction value in the next transport period is calculated according to the amount of deviation from the assumption of the embroidery data length calculated in.

The correction value of the staining data length calculated in S915 is shown in the numerical value in the 8th row of the table of FIG. 14, and can be expressed by the following formula.
Dyeing data correction value = (corrected thread transport length)-(corrected thread transport length assumed when transporting needle thread consumption (corrected predicted value)-(from the assumption of data consumption of the embroidery machine) Misalignment)

Further, (corrected yarn transport length) used for the calculation in S915 corresponds to the numerical value in the third row of FIG. 14, and (the needle thread consumption amount assumed when transporting the corrected yarn transport length). (Corrected predicted value) corresponds to the numerical value on the 10th line, and (Difference from the assumption of data consumption of the embroidery machine) corresponds to the numerical value on the 11th line.

Therefore, in FIG. 14, the dyeing data correction value set in after the needle thread transport length correction after each detection timing shown in the 5th line is (the next numerical value in the 3rd line)-(10th line). Next time numerical value)-(this time numerical value on the 11th line)}.

When the numerical values of the staining data correction values in the table of FIG. 14 are applied to the above formula and examined,
The staining data correction value set after the first detection is 9.4-9- (-0.1) = 0.5,
The staining data correction value set after the second detection is 9-9-0 = 0,
The staining data correction value set after the third detection is 10.7-11-0 = -0.3,
The staining data correction value set after the fourth detection is 11.1-11- (0.2) =-0.5,
The staining data correction value set after the fifth detection is 10.2-10-0 = 0.2.

Note that FIG. 14 shows the detection and correction for 6 times, but in the subsequent control as well, the path length at the detection timing for each specified time and the thread consumption assumed at the specified time this time are used. Correct the next thread transfer length as appropriate. Then, the dyeing data length is appropriately corrected according to the deviation between the thread consumption amount assumed in the next transfer period using the thread transfer length and the embroidery data consumption amount.

Returning to FIG. 8, in step S916, the correction of the dyeing data in the next transport period is reflected according to the dyeing data correction value. Specifically, depending on the staining data correction value, the first data of the staining data in the next transport period is deleted, or dummy data is added immediately before the staining data.

Here, since the dyeing data length = the thread transport length, in this control example, the next dyeing data is increased or decreased according to the dyeing data correction value for the dyeing data having the same length as the thread transport length. In FIG. 14, the value obtained by adding the dyeing data correction value in the 8th row to the thread transport length after the next correction shown in the 3rd row is the next corrected dyeing data length shown in the 4th row. ..

In step S917, in the next transport period, transport at the adjusted transport speed, dyeing at the dyeing speed according to the adjusted transport speed based on the corrected dyeing data, and embroidery based on the embroidery data are performed. do.

Then, in step S918, when the specified time has elapsed from S902, it is assumed that the next detection timing has been reached, and the process returns to the front of S902, and S902 to S917 are carried out in the same manner as in the current transport period to adjust the transport speed. And correct the staining data to reflect it. Then, the dyeing operation, the transport operation, and the embroidery operation according to the dyeing data or the adjusted dyeing data are executed until the dyeing data is completed in step S919.

When all the dyeing data is completed in step S919, the process returns to S19 in FIG. 7, and the dyeing / transporting operation in the dyeing apparatus 1 and the embroidery operation in the embroidery apparatus 2 are terminated.

As described above, in the dyeing apparatus in this control example, the path length is calculated by using the specified time as a trigger, and the thread transport length in the specified time is adjusted to eliminate the speed difference between the needle thread and the bobbin thread in the embroidery device. At the same time, it is possible to suppress the misalignment of the color of the needle thread. Furthermore, in consideration of the adjusted transport speed, the dyeing data length is adjusted at specified time intervals according to the expected thread consumption for the next time and the amount of deviation from the assumed embroidery data length, which makes it stand out as embroidery. Before that, the lack of staining data is replenished and corrected, and the surplus data is truncated and corrected. This makes it possible to minimize the amount of thread color deviation in the embroidery device without causing a cumulative error between the thread consumption on the embroidery device side and the thread dyeing length.
