Description

The present invention relates to a setting of a yarn breakage detection device and a method for executing a yarn breakage detection process in a creel device, and a yarn breakage detection device in a creel device.

In a preparation stage of a warp beam used for a loom or the like, yarns are drawn all at once from a large number of yarn feeders mounted on a creel device and wound around the beam by a winding device or the like. Even if one of the many yarns drawn from the creel device breaks, the number of yarns wound around the beam will be insufficient. Therefore, it is necessary to detect the yarn breakage for all the yarns in the winding process. There is. In addition, when a yarn breakage occurs, it is desirable that an operator can identify which yarn breakage has occurred in order to repair the yarn breakage.

Therefore, a yarn break sensor is provided for each of a large number of support members for supporting a plurality of yarn feeders, and signals from the yarn break sensors are paralleled to a plurality of controllers provided for each row of the support members. Further, the thread break information from each controller is monitored and processed by the central processing unit.

By the way, the creel device has a number of support members according to the number of support members so that a large number of yarn feeders can be inserted. And the rows are arranged in a number of rows. Specifically, for example, the creel device is provided with 1000 support members so that 1000 yarn feeders can be mounted, and this support member is provided over 100 rows with 10 as one row. And the like. In the case of the example, the number of the above-described controllers, that is, 100 is provided.

In general, serial communication is used for transmission / reception of data between a large number of controllers and the central processing unit as seen in Patent Document 1. However, when serial communication is used for data transmission / reception, there are the following problems.

(1) Each control device and central processing unit must be equipped with a communication IC, and a communication protocol must be created, which complicates the hardware and software, and increases the cost of the device. .

(2) When a yarn breakage occurs in any of the yarn feeders, the transmission of data to the central processing unit depends on the polling cycle even if the controller corresponding to the yarn feeder row receives a yarn breakage signal. Therefore, depending on the timing of yarn breakage with respect to the polling cycle, the yarn breakage detection by the central processing unit may be delayed.

As described above, even when any one of the many drawn out from the creel device is cut, it is necessary to stop the winding. Moreover, if the winding is not stopped immediately upon detecting the yarn breakage, the yarn end of the broken yarn may be caught in the take-up beam, or it may be entangled with another yarn and cause further yarn breakage. As a result, there is a problem that the subsequent thread breakage repair work becomes difficult.

To solve the problem (2), according to the technique of Patent Document 1, when data to be transmitted is generated in addition to the serial communication line, the controller (slave station) is connected to the central processing unit. It is disclosed that a bus request line for requesting transmission immediately to the (master station) is provided. According to the configuration, for example, when the above-described thread breakage occurs and it is necessary to immediately transmit a thread breakage signal from the corresponding slave station to the master station, the sensor outputs the signal regardless of the polling cycle. Since the slave station that has received the thread break signal can immediately notify the master station to that effect, the problem of delay in detecting the thread break by the master station can be avoided.

In the technique described in the above prior art, when data to be transmitted immediately to the master station is generated in each slave station, a transmission request is made from the slave station to the master station through the bus request line described above. Since the subsequent data communication is performed by the serial communication described above, the above problem (1) still remains.
Japanese Patent Laid-Open No. 5-78925

Accordingly, an object of the present invention is to provide a central controller for monitoring the yarn breakage of the entire controller and the plurality of controllers provided corresponding to the plurality of sensors for each of the plurality of support member rows for supporting the yarn feeder. In a creel yarn breakage detecting device connected to a processing device, the configuration of the device is simplified and the cost of the device can be kept low.

Based on the above problems, the present invention includes a plurality of support members arranged in parallel in the vertical direction in order to support a large number of yarn feeders, and a plurality of support members provided corresponding to each support member. A creel device comprising a yarn break sensor, a plurality of controllers that receive signals from the yarn break sensors in the corresponding row, and a central processing unit that is connected to the plurality of controllers and monitors yarn breaks in the entire creel device In the yarn breakage detecting device, a central processing unit and a plurality of controllers are connected in series by a first transmission line, and the central processing unit and an input port of each controller are connected by a bus by a second transmission line. Yes.

Then, at a predetermined timing, the central processing unit sets the output state of the signal output to each controller via the second transmission line as one of a plurality of modes including initial setting and yarn breakage detection. A command signal for causing the most upstream controller to execute processing corresponding to the mode is output via the first transmission line.

Each controller is set to a predetermined mode based on the output state of the signal from the central processing unit in the second transmission line, and from the central processing unit or the upstream controller via the first transmission line. A predetermined process corresponding to the mode is executed in accordance with the output command signal, and a command signal for causing the controller connected downstream to execute the same process is output.

Further, in the yarn breakage detecting device in the creel device of the present invention, the output port in each of the controllers can output a signal in parallel, and each controller and the central processing unit can be connected via the output port. It is assumed that the bus is connected by a third transmission line, and each controller obtains predetermined information regarding the mode in accordance with a command signal from the central processing unit or the upstream controller, and a signal corresponding to the information. May be output to the central processing unit via the third transmission line.

Furthermore, the predetermined information can be information based on a signal from the yarn break sensor. Each controller determines the process to be executed according to the set mode even if the command signal from the central processing unit or the upstream controller is the same signal, and the process according to the mode. Can be performed.

According to the present invention, data transmission / reception is not performed between the central processing unit and each controller using serial communication as in the prior art. Necessary information can be exchanged between the processing device and each controller.

That is, the central processing unit simply switches the output state of the signal in the second transmission line in order to switch the mode of each controller, and the command signal is a simple signal such as a one-shot trigger signal (pulse signal). It is only necessary to output the necessary information, and on the premise of the output state (mode state) of the signal in the second transmission line to each controller, the necessary information is transmitted by the input of the simple command signal described above. Can be done. Therefore, a simple configuration in terms of hardware and software can be achieved, and the apparatus cost (cost) can be kept low.

[Mechanical configuration of the creel device 1]
1 to 4 show a mechanical configuration of a V-shaped creel device as an example of a creel device 1 to which the present invention is applied. 1 to 4, the creel device 1 has machine frames 3 having a V-shape in plan view so as to support a large number of yarn feeders 2, and are attached to these machine frames 3. The yarn feeder frame 3b thus provided has a plurality of rows of support members 3a arranged in parallel in the vertical (vertical) direction.

That is, the support members 3a are arranged in the creel device 1 in a multistage multi-row shape. In the creel device 1 of this embodiment, 10 support members 3a are provided for each row in the vertical direction, and N rows of the support members 3a are provided in the horizontal direction, for a total of 10 × N yarn feedings. It shall be comprised so that the body 2 can be supported. In the warping process, a necessary number of yarn feeders 2 are arranged at appropriate positions with respect to the 10 × N support members 3a.

The yarn 4 as the yarn drawn out from all the yarn feeders 2 passes through a plurality of yarn breakage sensors 9 provided corresponding to the respective support members 3a, and then joins at the position of the heel 5 to obtain a predetermined value. It becomes one sheet-like thread having a width. The sheet-like yarn 4 is wound around a winding beam 8 of a winding device 7 through a plurality of guide rolls 6.

The yarn breakage sensor 9 is provided for each of the ten support members 3a in each row, and the yarn 4 is guided through a member that contacts and guides the yarn 4 drawn from the yarn feeder 2 mounted on the corresponding support member 3a. And the like that detect the vibration and movement of the yarn accompanying the pulling of the yarn, or the one that detects the tension of the yarn 4. In this embodiment, a controller 11 is provided for each row of the support members 3a, and ten yarn breakage sensors 9 in each row are connected to the controller 11 provided corresponding to the row. It shall be. Therefore, the number of controllers 11 matches the number N of columns. The yarn break sensor 9 and the controller 11 constitute a part of the yarn break detection device 10.

[Electrical configuration of the yarn breakage detection device 10]
Next, FIG. 5 shows an electrical configuration of the yarn breakage detecting device 10. The creel device 1 includes a yarn breakage detecting device 10 for detecting the yarn breakage of a large number of warp yarns 4 drawn out from all the yarn feeders 2 that are set.

As shown in FIG. 5, the yarn breakage detection device 10 includes a central processing unit 12 in addition to a plurality (10 × N) of yarn breakage sensors 9 and a plurality (N) of controllers 11. The yarn breakage sensor 9 is provided for each support member 3a, detects the withdrawal of the yarn 4 from the yarn feeder 2 mounted on the support member 3a, and outputs a signal indicating it. The controller 11 in each row receives signals from ten yarn break sensors 9 in the corresponding row. In addition, the central processing unit 12 is connected to all the controllers 11 and monitors the yarn breakage of the entire creel device 1.

In FIG. 5, # 1, # 2,..., #N are unit numbers corresponding to the controllers 11 in each column, and are also address numbers of the controllers 11 at the same time. These controllers 11 include an input port 15, an output port 18, a control unit 16, a storage unit 17, and a display lamp 21. The central processing unit 12 is provided with a display device 20.

The central processing unit 12 and the N controllers 11 are connected in series by a first transmission line 13. That is, the input port 15 of the controller 11 of # 1 is connected to the central processing unit 12, and the output port 18 of the controller 11 of # 1, # 2,. Are connected to the input port 15 of the controller 11 of # 2,. The output port 18 of the #N controller 11 is connected to the central processing unit 12.

The first transmission line 13 outputs a command signal when the central processing unit 12 requests each controller 11 for information such as the number of yarns and yarn breakage. The command signal output from the central processing unit 12 via the first transmission line 13 is first input to the input port 15 of the controller 11 of # 1, and then to the downstream controller 11 after # 2. On the other hand, similar signals are sequentially input from the output port 18 of the controller 11 on the upstream side to the input port 15. Therefore, here, the controller 11 of # 1 closest to the central processing unit 12 becomes the controller 11 on the most upstream side.

The central processing unit 12 and each controller 11 are bus-connected by one (1 bit) second transmission line 14 for setting the operation mode, and for setting the operation mode from the central processing unit 12. The signal is input in parallel to the input port 15 of the controller 11 of # 1, # 2,..., #N using the second transmission line 14 as a common signal transmission path.

The second transmission line 14 includes the number of effective yarn break sensors 9 (number of yarns) to be described later, the operation mode for executing the detection / setting operation of the position (thread position), and the yarn break position detecting operation to be described later. It is assumed that each controller 11 is set to one of the modes depending on the output state of the line signal. In the following, it is assumed that each controller 11 is set to the yarn position setting mode when the output state of the signal in the second transmission line is OFF, and is set to the yarn break position detection mode when ON. .

In this way, the input port 15 of each controller 11 has a signal from the central processing unit 12 or the upstream controller 11 via the first transmission line 13 and a center via the second transmission line 14. In addition to signals from the processing device 12, signals from the yarn breakage sensors 9 of the ten yarn feeders 2 in each row are input in parallel, and the input processing is performed.

Further, the output port 18 of each controller 11 is also bus-connected to the central processing unit 12 by a third transmission line 19. The third transmission line 19 is provided to send, for example, a stop signal accompanying yarn breakage or a signal indicating information on the yarn break position from each controller 11 to the central processing unit 12. Note that a display 20 is attached to the central processing unit 12.

The effective position setting of the yarn break sensor 9 (position setting of the loaded yarn feeder 2) is a matter of initial setting performed before starting the continuous operation of the creel device 1. In addition to this, there are address setting and stage number setting. The address setting for each controller 11 is set so that each controller 11 exchanges various signals with the central processing unit 12 while identifying itself using the address set for each controller 11. There are various methods for setting the address. For example, a hardware setting device such as a dip switch is incorporated in each controller 11, and the operator can manually set the device by operating each setting device.

As another initial setting item, the number of stages for setting the number of yarn feeders 2 that can be mounted in each row, that is, the number of support members 3a (number of stages) to the controller 11 is also set. The method for setting the number of stages is not particularly limited, and may be set by a manually operated switch incorporated in each controller 11 as in the address setting. As described above, in this example, each controller 11 is provided for each row of support members 3a and the number of support members 3a arranged in the vertical direction (the number of steps) is ten. For this reason, 10 which is the number of this supporting member 3a is set to the controller 11 of each row | line | column as a step number.

The purpose of setting the number of stages is to let each controller 11 know the number of support members 3a (number of stages) in each row, that is, the number of yarn break sensors 9 connected to each controller 11. With the detection of the position and number of effective thread break sensors 9, each controller 11 can compare the number of thread break sensors 9 connected to itself with the number of effective thread break sensors 9 therein. This is because it is possible to visually recognize the coincidence / mismatch between the two by turning on the display lamp 21 attached to the controller 11. This is because an abnormality (for example, forgetting to set the yarn supplying body 2 or an abnormality in the yarn supplying body 2 or the yarn breakage sensor 9) in the row where the yarn supplying bodies 2 are supposed to be set on all the support members 3a. ) Is effective in grasping when it occurs.

As described above, after address setting or the like is performed at the initial setting stage, an operation for setting the position of the effective thread breakage sensor 9 is executed. In this embodiment, in addition to the operation for setting the position of the effective thread break sensor 9, the number of the effective thread break sensors 9 (number of threads) is detected, and the number of threads detected by each controller 11 is detected. The operation of comparing the total number with the set value is executed in the central processing unit 12. Hereinafter, both of these operations are collectively referred to as “yarn number / position detection operation”, and an operation mode for executing the operation is referred to as a yarn number / position detection mode.

In this yarn number / position detection operation, each controller 11 is set to the yarn number / position detection mode. As described above, this mode setting is switched by the output state (ON / OFF) of the signal from the central processing unit 12 in the second transmission line 14, and in this example, the signal on the line is OFF. It is sometimes assumed that the yarn number / position detection mode is set. In the present embodiment, another mode to be switched, that is, an operation mode set when the signal on the line is ON, is accompanied by the occurrence of yarn breakage of the yarn 4 pulled out from the yarn feeder 2. A mode for executing a yarn break position detecting operation to detect the position is set. Hereinafter, the yarn number / position detection operation and the yarn break position detection operation will be described in detail.

[Thread number / position detection]
The position (yarn position) of the effective thread break sensor 9 for each controller 11 is set out of a plurality (10 in this embodiment) of thread break sensors 9 to which the controller 11 is connected. This is performed in order to grasp the position (stage position) of the yarn break sensor 9 corresponding to the yarn feeder 2.

That is, as described above, when the creel device 1 is provided with the support member 3a of 10 stages × N rows, the creel device 1 can be mounted with a maximum of 10 × N yarn supplying bodies 2. It has become. However, this is only the maximum number that can be mounted, and the number of yarn feeders 2 that are actually placed on the creel device 1 is almost less than 10 × N. When the number of the yarn feeding bodies 2 to be set is small, there is a portion on the creel device 1 where the yarn feeding body 2 is not set on the support member 3a.

On the other hand, the yarn breakage sensors 9 are provided corresponding to all the support members 3a, and are installed on the creel device 1 by the same number as the support members 3a (= the maximum number of yarn feeders 2 that can be mounted). ing. Accordingly, the yarn break sensor 9 is also present at a position where the yarn feeder 2 is not set. Therefore, when the yarn break sensor 9 is in an operating state, its output signal always indicates a yarn-free state (thread break state). It will be a thing.

Here, it is conceivable that the yarn break sensor 9 provided corresponding to the support member 3a on which the yarn feeder 2 is not mounted is inactivated by a switch operation or the like. Since it involves a switch operation, it is a heavy burden on the operator and operation mistakes are likely to occur. Therefore, when detecting the yarn breakage performed during the continuous operation of the creel device 1, the yarn breakage sensor 9 that does not correspond to the yarn feeder 2, that is, the yarn breakage sensor 9 that is not effective is not deactivated but is activated. It is preferable to exclude the signal while keeping the state.

For this reason, by setting (storing) the thread breakage sensor 9 that is not valid among the yarn breakage sensors 9 in the corresponding row connected to each controller 11 at that position, the yarn breakage detection is performed. During this, the signal from the thread breakage sensor 9 which is not effective can be ignored.

In addition, whether or not the yarn breakage sensor 9 has normally detected the withdrawal of the yarn 4 from all the yarn feeders 2 that have been set up by grasping the number of effective yarn breakage sensors 9 (number of yarns) in advance. It can be determined whether or not.

That is, all of the predetermined number of yarn feeders 2 are set, the yarn 4 is normally pulled out from the set yarn feeders 2, and all the yarn break sensors 9 are operating normally. In this case, it is sufficient to detect and set the position of the effective yarn breakage sensor 9 described above. However, depending on the case, the number of the yarn supplying bodies 2 is less than the expected number due to forgetting the setting of the yarn supplying bodies 2 or the yarn supplying bodies 2 are all set normally, but the yarn supplying bodies are not provided. 2 and the yarn break sensor 9 itself may not be able to detect the withdrawal of the yarn 4 for a specific yarn feeder 2. Furthermore, there is a case where a signal indicating that the yarn break sensor 9 corresponding to the position where the yarn feeder 2 is not set has detected the withdrawal of the yarn 4 is output due to an abnormality or disturbance of the yarn break sensor 9 itself. is there.

When all are normal, the number of effective thread break sensors 9, that is, the number of thread break sensors 9 that detect the withdrawal of the thread 4 should match the planned number of yarn feeders 2 to be set. It is. Therefore, by counting the number of effective yarn breakage sensors 9 and comparing the counted value with the planned number of yarn feeders 2 (the number of set values), all of the yarn feeders 2 are installed without omission, and It can be determined whether or not the withdrawal of the warp 4 from the loaded yarn feeder 2 is normally detected by the corresponding yarn break sensor 9.

[Thread count / position detection flow]
FIG. 6 shows the procedure of the above-described yarn number / position detection operation. In FIG. 6, the yarn number / position detecting operation is executed after completion of address setting for each controller 11 in the initial setting stage.

The central processing unit 12 starts a yarn number / position detection operation (START) at a predetermined timing, for example, at the time of completion of address setting or completion of setting of the number of stages, and outputs a signal on the second transmission line 14. Is set to OFF. The controller 16 of each controller 11 determines whether or not the yarn number / position detection mode is in effect from the signal output state (OFF) in the second transmission line 14 (step 301), and the output state is OFF. Based on this, the yarn number / position detection mode is turned ON to prepare for the operation (step 302). If the output state of the signal in the second transmission line 14 is ON, the yarn number / position detection mode is turned OFF, and the process is terminated (END) (step 308).

Along with this, the yarn break sensor 9 is activated, and the winding device 7 starts operation at a speed lower than the normal operation speed, and each yarn break sensor 9 detects whether or not the yarn 4 is pulled out. Start (step 303). The yarn break sensor 9 detects the withdrawal of the yarn 4 by its vibration and movement, and outputs a signal indicating it to the corresponding controller 11, and the detection signals of the plurality of yarn break sensors 9 in each row are: The signals are input in parallel to the input ports 15 of the corresponding controllers 11. Each controller 11 monitors the signal from each thread break sensor 9 in the corresponding row in the controller 16 and the output signal does not detect the withdrawal of the yarn 4 (specifically, a predetermined value) It is determined that the withdrawal of the yarn 4 from the yarn feeder 2 corresponding to the yarn breakage sensor 9 has not been detected because the vibration or movement of the yarn 4 is not detected.

As described above, in this embodiment, the winding device 7 is operated at a low speed in the yarn number / position detecting operation. This is because, at the initial setting stage, the yarn 4 is not normally drawn out from all the yarn feeders 2 that are to be set yet, and the yarn 2 drawn out at the initial stage is not a normal number. This is because there are not many cases. Specifically, at the initial setting stage, if the number of the drawn yarns 2 is not a regular number, a process is performed in which the yarns 2 are separated from the yarns 2 that can be properly wound and discarded. Accordingly, when the winding device 7 is operated at a high speed at the initial setting stage, such yarn removal (yarn waste) increases. For this reason, in order to reduce the amount of such yarn removal, the winding device 7 is operated at a low speed to perform the yarn number / position detection operation. However, when it is not necessary to consider the amount of yarn removal, the winding device 7 may be operated at a speed close to or equal to the speed during normal operation in the yarn number / detection operation.

Next, the controller 16 of each controller 11 receives a command signal for instructing detection of the number of yarns and its position output from the central processing unit 12 or the upstream controller 11 via the first transmission line 13. It is determined whether or not it has been done (step 304). Here, the command signal is a simple pulse signal (trigger signal of one shot pulse). When the pulse-like command signal is input from the central processing unit 12 or the upstream controller 11, the control unit 16 of each controller 11 detects the rising edge of the pulse and receives the input ( Command signal ON), the process proceeds to the next step (step 305). When the input of the command signal is not confirmed (when the command signal is OFF), the process returns to the previous step (step 304), and the step is repeated until the input of the command signal is confirmed. That is, in a state where the detection of the yarn 4 by the yarn break sensor 9 is continued, a standby state is prepared for the input of a command signal from the upstream side (step 303).

The controller 16 of each controller 11 holds the number of yarn breakage sensors 9 (number of yarns) and the position (yarn position) that detect the withdrawal of the yarn 4 when the rising edge of the command signal pulse is detected. This is stored in the storage unit 17 (step 305).

Next, each controller 11 outputs a pulse train signal including the same number of pulses as the number of yarns as a signal corresponding to the number of yarn breakage sensors 9 (number of yarns) stored in the above step 305 as its output port 18. To the central processing unit 12 via the third transmission line 19 (step 306).

Then, each controller 11 is a signal (output end signal) indicating that its own yarn number / position detection operation has been completed at the point where the output of the pulse train signal indicating the number of yarns to the third transmission line 19 has been completed. ), The same one-shot pulse signal as the input command signal is output to the downstream controller 11 (step 307), the yarn number / position detection mode is turned off (step 308), and the processing operation of itself is performed. finish.

When the output end signal is output from the upstream controller 11, the downstream controller 11 determines that this is a command signal for instructing detection of the number of yarns and the position of itself, and performs the same processing as described above. Execute.

In this way, the yarn number / position detection operation described above is executed in order from the # 1 controller 11 on the most upstream side, and the effective yarn breakage of the yarn breakage sensors 9 in the corresponding row is sent to each controller 11. The sensor 9 is set according to its position, and the number of effective yarn breakage sensors 9 from each controller 11 to the central processing unit 12, that is, the number of yarns 4 drawn from the yarn feeders 2 in the corresponding row. A pulse signal indicating the number of yarns 4 (number of yarns) detected by the yarn break sensor 9 is output. When the output end signal is output to the central processing unit 12 from the #N controller 11 on the most downstream side, the central processing unit 12 determines that the processing operation has been executed in each controller 11. Then, the subsequent comparison operation is executed.

In the comparison operation in the central processing unit 12, as described above, it is determined whether or not the total number of yarns detected by each controller 11 matches the planned number of yarn feeders 2 to be set. It is. Therefore, the number (total number) of yarn feeders 2 to be set is input to the central processing unit 12 as a set value in advance. The central processing unit 12 incorporates the number of pulses of the pulse train signal indicating the number of yarns sequentially output from the upstream controller 11 via the third transmission line 19 as described above (= detected value of the number of yarns). Counting is performed by a counter (not shown), and this counting is continued until the output end signal is output from the most downstream #N controller 11. When the output end signal is output from the #N controller 11 on the most downstream side, the count value up to that point is compared with the set value. , It is determined that all the yarn breakage sensors 9 to be activated are operating normally, and that all of the scheduled yarn feeders 2 are normally set and pulled out normally, and the yarn number / position detecting operation is normally performed. It can be determined that the operation has been completed, and the next operation can be performed. If the comparison results do not match, there is a possibility that either the yarn break sensor 9 or the yarn feeder 2 is abnormal. For this reason, there is a possibility that each yarn feeder 2 is checked or there is a possibility of a detection error, so it is conceivable to try again the above-described yarn number / position detection operation.

In the course of the above-described yarn number / position detection operation, each controller 11 compares the number of support members 3a (number of stages) in the corresponding row with the number of effective yarn breakage sensors 9 (number of yarns). The comparison result can be displayed by a display lamp 21 attached to the controller 11 so that the comparison result can be visually recognized. This is because, in the creel device 1, the yarn feeder 2 is generally loaded from the side closer to the winding device 7, and in such a case, as a result of the comparison operation by the central processing unit 12, This is effective for finding out which part is abnormal when the detected value of the number of yarns does not match the set value.

Specifically, as described above, in the creel device 1 including N × 10 support members 3a, the total number of yarn feeders 2 to be set is [10 × (N−5) +4]. Suppose that the yarn feeders 2 are packed in order from the row of the support members 3 a closer to the winding device 7 on the creel device 1. In this case, the yarn feeders 2 are not installed at all in the four rows far from the winding device 7 on the creel device 1, and the yarn feeders 2 are provided only on four of the ten rows in the fifth row. It will be set up. Therefore, in this case, for the five rows far from the winding device 7 on the creel device 1, the number of yarn feeders 2 set (number of effective yarn breakage sensors 9 / number of yarns) and the support member 3a Therefore, the display lamps 21 attached to the controllers 11 corresponding to this column are in a display state (for example, turned off) indicating that they do not match. Further, for the (N-5) row from the side closer to the winding device 7, the yarn feeders 2 are set on all the support members 3a, and therefore the display lamp 21 attached to the controller 11 corresponding to this row is Then, a display state (for example, lighting) indicating that the detected number of yarns and the number of support members 3a coincide with each other is set.

As a result of the comparison operation by the central processing unit 12, if the count value does not match the set value, forgetting to set the yarn supplying body 2 or an abnormality has occurred in one of the yarn supplying bodies 2 or the yarn breakage sensor 9. It is judged. When this abnormal part is in the (N-5) row from the side closer to the winding device 7, the display lamp 21 that should be lit (from the side closer to the winding device 7 in the (N-5) row). Any one of the indicator lamps 21) attached to each controller 11 corresponding to each row of the support member 3a is turned off, so that it is possible to easily grasp which row has an abnormality and easily find the abnormal portion. Can be done. Moreover, when the said abnormal location exists in five rows far from the winding device 7, all the display lamps 21 corresponding to the said (N-5) row will be in a lighting state. From the display state of the display lamp 21, it can be understood that the abnormal part is in the five rows far from the winding device 7, and the operator only has to examine the above five rows. It is easy to find abnormal parts.

(Thread break position detection)
As described above, when the setting of the position of the effective yarn break sensor 9 with respect to each controller 11 is normally completed, it is determined that the initial setting has been completed, and the central processing unit 12 determines that the creel device 1 and the winding device 7 and the like. Start operation. While the creel device 1 is in operation, the withdrawal of the yarn 4 from the corresponding yarn feeder 2 by each yarn break sensor 9 is detected, and the yarn break is monitored. When the yarn break is detected, the central processing unit 12 stops the operations of the creel device 1 and the winding device 7 and performs a yarn break position detection operation.

The yarn break position detecting operation here refers to a yarn feeder in which the yarn breakage occurs when the yarn 4 pulled out from one of the yarn feeders 2 is operating during operation of the creel device 1. This is an operation performed to detect the position of 2. In the above yarn breakage detection, each controller 11 monitors the output signals of a plurality (10) of thread breakage sensors 9 connected via the input port 15, and the output signals indicate a thread breakage. Each controller 11 outputs a signal indicating yarn breakage detection to the central processing unit 12 when confirming this state.

(Thread break position detection flow)
FIG. 7 shows an operation procedure for detecting the yarn break position. In FIG. 7, after the start of the thread break position detection operation (START), it is first determined whether or not the initial setting has been completed (step 401), and the above address setting and the position of the effective thread break sensor 9 are determined. If it is determined that the initial setting such as setting has not been completed (NO), the yarn breakage detection is not executed and the process is terminated (END). When it is determined that the initial setting has been completed (YES), the operation of the creel device 1 and the winding device 7 is started as described above, and the process proceeds to the next step. The control unit 16 determines the output state of the signal on the second transmission line 14 from the central processing unit 12 in that state (step 402).

In step 402, under the condition that the initial setting is in the completed state, the output state of the signal in the second transmission line 14 is determined by each controller 11 and the output state of this line signal is OFF. Each controller 11 is not set to the yarn breakage position detection mode, and proceeds to the next step to monitor the yarn breakage of the yarn 4 drawn from the yarn feeder 2 by the output signal from the yarn breakage sensor 9. (Step 403). Here, the yarn breakage monitoring is performed in the state where the output state of the signal in the second transmission line 14 from the central processing unit 12 is OFF, but the output state of the signal in the second transmission line 14 is as follows. This is the same as the output state indicating the yarn number / position detection mode. However, in this case, a condition is added that the initial setting is completed as described above, and under this condition, even if the output state of the signal in the second transmission line 14 is also OFF, Each controller 11 is not set to the yarn number / position detection mode, and is in a state of performing yarn breakage monitoring.

As a result of monitoring the signal from the corresponding thread break sensor 9 by each controller 11, if it is detected that the signal from any one of the thread break sensors 9 indicates a thread breakage, the thread break is detected. The controller 11 immediately outputs a pulse-like signal indicating the occurrence of yarn breakage via the third transmission line 19 in order to immediately notify the central processing unit 12 of the occurrence of yarn breakage (step 404). Note that this pulse-shaped signal is a simple pulse signal (trigger signal) that does not include position information or the like.

When the pulse signal is input via the third transmission line 19 while monitoring the yarn breakage, the central processing unit 12 determines that the yarn breakage has occurred and stops the winding device 7 and the like. The drawing of the yarn from the yarn feeder 2 is stopped, and the signal output state in the second transmission line 14 is set to a state indicating the yarn break position detection mode, that is, an ON state.

The controller 11 that has detected the yarn breakage determines whether or not the output state of the signal in the second transmission line 14 in the control unit 16 is a state (ON) indicating the yarn breakage position detection mode (step 405). If the signal on the second transmission line 14 is ON, the thread break position detection mode is set (step 406).

Here, as described above, when the central processing unit 12 sets the output state of the signal in the second transmission line 14 to the ON state indicating the yarn break position detection mode, all of the controllers other than the controller 11 that has detected the yarn break. Similarly, the controller 11 is set to the yarn break position detection mode (step 406 '). Each controller 11 requests output of the yarn break position from the central processing unit 12 or the upstream controller 11 via the first transmission line 13 in the state set in the yarn break position detection mode. It prepares for the output of the command signal (steps 407, 407 '). The command signal for requesting output of the yarn break position can be, for example, a pulsed command signal (a trigger signal for one shot pulse).

In this state, the central processing unit 12 outputs a command signal requesting the output of the yarn break position described above, and the controller 11 that detects the yarn break is connected to the upstream controller 11 (the most upstream controller 11). In this case, when the command signal is received from the central processing unit 12) (step 407), the controller 11 detecting this yarn breakage detects the rising edge of the pulse, and at that time, first corresponds to its own address. As a signal, for example, a pulse train signal including a number of pulses matching the address is output (step 408).

Next, at a predetermined time interval, a signal indicating the number of stages of the yarn break sensor 9 that has detected the yarn break (position of the yarn feeder 2 where the yarn break has occurred = thread break position) is output (step 409). This signal may be the same pulse train signal as described above.

The predetermined time interval is for distinguishing between the signal indicating the address and the signal indicating the yarn break position. For example, the time interval is set to 300 msec, and the counter of the central processing unit 12 If no new pulse is input when the time exceeds 300 msec, the count is set to end once. By doing so, first, when all the pulses corresponding to the address are input, the count is once stopped, the count value is reset after being stored, and then the count of the pulse corresponding to the thread break position is started. Is done. In this case, of course, the pulse period of the pulse train signal corresponding to the address and the yarn break position is set shorter than 300 msec.

The controller 11 that has detected the yarn breakage in this way outputs a signal including its own address and yarn break position as information as described above, and then, as a signal indicating the end of yarn break position output, The same pulse-like signal is output to the controller 11 on the downstream side (step 410), and the yarn break position detection operation ends (END).

The controller 11 on the downstream side determines that the signal indicating the end of the yarn break position output output from the controller 11 on the upstream side is a command signal for requesting the output of the yarn break position with respect to itself, and is similar to the above. Execute the process. However, the controller 11 that has not detected the yarn breakage does not output the signal including its own address and information on the yarn breakage position as described above even if the command signal is received in step 407 ′. Only the signal indicating the end of the cut position output is output to the downstream side, and the end of the yarn break position detection operation (END) is reached (step 410 ').

Here, as described above, the pulse-like command signal for requesting the output of the yarn break position output from the central processing unit 12 or the upstream controller 11 in this yarn break position detection operation is the number of yarns / position described above. This is a one-shot pulse trigger signal that is the same as the command signal that commands the detection of the number of yarns and their position in the detection operation, and there is no difference between these command signals. Therefore, each controller 11 has a function of determining the processing content according to the operation mode set at that time.

Specifically, when the command signal is input in the yarn number / position detection mode state, each controller 11 determines that the yarn number / position detection operation starts, and in the yarn break position detection mode state, When the command signal is input, it is determined that the command is for outputting yarn breakage information. Accordingly, the command signal for each controller 11 may be a signal that triggers execution of a predetermined process corresponding to the mode, and the processing content is determined on the controller 11 side. A signal output from the first transmission line 13 through the first transmission line 13 may be a simple signal such as a pulse signal.

When the command signal is output from the #N controller 11 on the most downstream side, the central processing unit 12 determines that the detection of the yarn break position has ended, and the signal output state in the second transmission line 14 again. Does not indicate the yarn break position detection mode.

The central processing unit 12 is provided with a display 20 and displays information (address and number of steps) relating to the above-described thread breakage. The operator can easily identify the yarn feeder 2 that has been broken by reading this information. For this reason, repair work can be performed quickly. In addition, after the yarn break repairing work is completed, the winding device 7 and the like starts regular operation again by the operation of the operator. Further, the information on the thread break is stored as data in the central processing unit 12 as necessary, and information for a plurality of past times can be confirmed.

The present invention is not limited to the above-described embodiments, and can be modified and implemented. In the above embodiment, various modes are set according to the signal output state in the second transmission line 14. However, the mode setting is not necessarily determined only by the signal output state in the second transmission line 14. For example, it may be determined in combination with another precondition. That is, even if the output state of the signal in the second transmission line 14 is the same, different modes may be set depending on the premise thereof, for example, whether or not the initial setting is completed.

Moreover, in the said Example, although the controller 11 shall be provided corresponding to each row | line | column of the supporting member 3a, it is not restricted to this, The controller 11 has multiple rows | lines by the row | line | column of the supporting member 3a, for example, It may be provided every two or three rows. Furthermore, the number of support members 3a corresponding to each controller 11 is not limited to the same number, but for example, the number of support members 3a corresponding to two adjacent controllers 11 and 11 is different. It may be.

When a plurality of columns correspond to each controller 11, the effective position of the thread break sensor 9 is set by a combination of a column and a position (for example, the m-th row of the corresponding n-th column). ) Or a simple serial number (for example, when two rows of thread breakage sensors 9 correspond to the controller 11, 1 in order from the top of the row close to the winding device 7). To 20) may be set. In the case where the continuation number is set as described above, the central processing unit 12 can grasp from the position number how many rows and what number of stages the thread breakage sensors 9 correspond to the controller 11. Thus, it is preferable to set information on the number of columns and the number of stages corresponding to each controller 11.

In the above embodiment, the number of the second transmission line 14 is one (1 bit), and two modes can be set according to the output state (ON / OFF) of the signal from the central processing unit 12. The number of the second transmission lines 14 is two (2 bits), and four modes can be set by combining the output states (ON / OFF) of the signals from the central processing unit 12 in both the second transmission lines 14 and 14. It is good. For example, in the above-described embodiment, the address setting and the stage number setting are manually set by a switch operation or the like. However, these are also automatically set, and one second transmission line 14 and the other second transmission line are set. Each output state of the signal on the transmission line 14 is an address setting mode when ON-ON, a stage number setting mode when ON-OFF, a thread number detection mode when OFF-ON, and a thread breakage when OFF-OFF. A detection mode can be considered.

FIG. 8 shows an example in which the number of second transmission lines 14 is two (2 bits) and four modes can be set. The address setting mode when the signal output state of one of the two second transmission lines 14 is ON-ON, the stage number setting mode when ON-OFF, the number of yarns when OFF-ON It is conceivable to use a thread breakage detection mode when the detection mode is OFF-OFF. Therefore, if there are two second transmission lines 14, in addition to the yarn number detection operation and the yarn breakage detection operation described above, the address setting operation and the stage number setting operation can be automatically performed by a program.

[Address setting flow]
FIG. 9 shows an operation order of automatic address setting. The automatic address setting for each controller 11 is performed at the initial stage of the initial setting, and is automatically started when the power of the creel device 1 is turned on.

In FIG. 9, when the power of the apparatus is turned on, the central processing unit 12 starts an automatic address setting operation (START). First, the signal output state in the second transmission line 14 indicates the address setting mode. A state, that is, each output state of signals in one and the other of the two second transmission lines 14 and 14 is set to ON-ON. The controller 16 of each controller 11 determines whether or not it is the address setting mode from the output state of the signals on the two second transmission lines 14 and 14 (step 101), If the output state is ON-ON, it is determined that the address setting mode is indicated (YES), and the address setting mode is set to ON (step 102). On the other hand, when the signal output state on the two second transmission lines 14 is not the address setting mode (NO), the controller 11 is set to another mode (step 110).

When the address setting mode is set to ON, each controller 11 clears the address stored up to that point in the storage unit 17 and resets a counter (not shown) built in the control unit 16 (counting). 0) (step 103), and waits for the output of a signal from the central processing unit 12 or the upstream controller 11 transmitted via the first transmission line 13.

Thereafter, the central processing unit 12 sends a signal including information corresponding to the address to the # 1 controller 11 on the most upstream side via the first transmission line 13, that is, the address of the controller 11 of # 1. The pulse train signal corresponding to is output. In this example, it is assumed that the pulse train signal output via the first transmission line 13 includes a number of pulses that matches the address of the controller 11 that is the output destination. In this example, as described above, the addresses of the controllers 11, # 1, # 2,..., #N are set to 1, 2,. Therefore, the signal output from the central processing unit 12 to the controller 11 of # 1 is a pulse train signal having 1 pulse.

Next, the controller 11 of # 1 determines the input of the pulse train signal from the central processing unit 12 (step 104). In other words, if the detection of the rising edge of the pulse is not confirmed (NO), the standby state is continued to prepare for the pulse train signal from the central processing unit 12. On the other hand, if the detection of the rising edge of the pulse is confirmed (YES), in the next step, the count value 0 of the counter built in the control unit 16 is determined based on a predetermined calculation rule (in this example, +1). +1 is added to (step 105).

Next, an operation for confirming the number of pulses included in the output pulse train signal is performed. Specifically, it is determined whether or not a predetermined time has elapsed from the time when the rising edge of the pulse is detected (step 106). If the predetermined time has not elapsed (NO), the rising edge of the pulse is detected again. It is confirmed whether or not (step 107).

The predetermined time is set to an appropriate time value based on the pulse period of the pulse train signal, and is set to a time longer than the pulse period of the pulse train signal. Specifically, for example, when the pulse period of the pulse train signal is 10 msec, the predetermined time may be 20 msec. Therefore, when the number of pulses included in the pulse train signal is 2 or more, the detection of the rising edge of the pulse is confirmed again before the predetermined time elapses (step 107), and the process returns to the previous step again (step 106).

However, in the case of the controller 11 of # 1, since the number of pulses included in the pulse train signal from the central processing unit 12 is 1, the rise of the next pulse is not detected even after a predetermined time has elapsed. Accordingly, it is determined in step 106 that a predetermined time has elapsed (YES). As a result, the control unit 16 in the # 1 controller 11 determines that the output of the pulse train signal from the central processing unit 12 has been completed, and proceeds to the next step, and stores the count value 1 up to that time in the storage unit 17. And stores 1 in the storage unit 17 as the address of the controller 11 # 1 (step 108).

Next, the controller 11 of # 1 uses the information related to the address of the input signal, that is, the number of pulses of 1 and the address of the controller 11 of # 2 on the downstream side based on the calculation rule described above. Corresponding information (2) is obtained, and a pulse train signal including this information, that is, a pulse train signal having two pulses, is output to the input port 15 of the controller 11 # 2 via the output port 18 (step 109). ). When this output is completed, the # 1 controller 11 determines that its own address setting is completed, turns off the address setting mode, and ends the address setting operation (step 110).

Thereafter, each controller 11 on the downstream side recognizes its own address by the input pulse train signal as well as the controller 11 of # 1 described above, stores the address, and further controls the downstream side. Information corresponding to the address of the device 11 is obtained based on the set operation rule, and a pulse train signal including the information is output to the controller 11 on the downstream side. In this way, the address for each controller 11 is automatically set sequentially from the upstream side to the downstream side.

According to the above processing operation, the #N controller 11 on the most downstream side outputs a pulse train signal having a pulse number N + 1 to the central processing unit 12 via the first transmission line 13. Therefore, the central processing unit 12 has a function of discriminating the pulse train signal returned from the #N controller 11, and within a predetermined time from when the pulse train signal is first output to the # 1 controller 11. It can be determined whether or not the pulse train signal having the number of pulses N + 1 is input from the #N controller 11.

If any one of the controllers 11 is abnormal or if an error such as a count error or a calculation error occurs in the processing related to the address setting, a signal is input to the central processing unit 12 within the predetermined time described above. In some cases, the number of pulses may be small even if a signal is input within a predetermined time. In such a case, the central processing unit 12 executes the address setting operation again, or informs the operator of the fact by an alarm or warning display. If it is a simple processing error, there is a possibility that the normal address can be set by re-execution. Therefore, the address setting operation may be executed again and an alarm or the like may be output when the same state is still reached.

Here, the information corresponding to the address included in the signal is the number of pulses in the pulse train signal. However, the present invention is not limited to this. For example, the pulse width (time from the rise to the fall of the pulse) or the pulse period (continuous 2 The time from the rise of the first pulse of one pulse to the rise of the second pulse). For example, if the pulse width (pulse interval) is 1/1000 to 9/1000 msec, the address can be set as 1, and if it is 10/1000 to 19/1000 msec, the address can be set as 2,. In this case, the above-described calculation rule is set with respect to time, for example, +10 msec. The present invention is not limited to any of the above cases, and any form of signal may be used as long as it can indicate an address in a simple form.

In the above example, regarding the serial connection of the controller 11 by the first transmission line 13, the controller # 1 closer to the central processing unit 12 is connected to the upstream side in the signal transmission direction on the first transmission line 13. However, the present invention is not limited to this, and the #N controller 11 far from the central processing unit 12 may be the upstream side. When the #N controller 11 is on the upstream side, the #N controller 11 farthest from the central processing unit 12 becomes the most upstream controller 11, and the first transmission line 13 is connected from the central processing unit 12 to the first transmission line 13. First, the signal sent through the controller 11 is input to the input port 15 of the farthest #N controller 11. The signals output from the upstream #N controller 11 via the first transmission line 13 are sequentially sent to the downstream controller 11, that is, the controller 11 closer to the central processing unit 12. Will be.

In addition, as in the above example, the address of the controller 11 on the most upstream side is set to the smallest value 1, and the address is set so that the value sequentially increases toward the downstream side. The reverse may be possible. For example, when the #N controller 11 farthest from the central processing unit 12 is set to the most upstream side as described above, the address is not set to 1, but is set to N + 1, and the downstream side thereof is set to N + 1. The addresses of the controller 11 may be N-1, N-2,. That is, the above-described calculation rule is to add the predetermined calculation value 1, but not limited to this, the predetermined calculation value may be subtracted. An arithmetic rule may be set so that multiplication or division is performed to obtain the address of the controller 11 on the downstream side.

If the same calculation rule is uniformly set for all the controllers 11, the addresses set in the respective controllers 11 are inevitably sequentially according to a predetermined rule from the upstream side to the downstream side. Different values. As described above, the addresses set in the respective controllers 11 need only have different values sequentially with a predetermined rule in the arrangement order, and any calculation rule may be used.

[Set the number of steps]
As described above, the number of stages is the number of yarn supplying bodies 2 that can be mounted in each row in the creel device 1, that is, the number of support members 3a for supporting the yarn supplying bodies 2 in the vertical direction. This is performed following the normal address setting. The purpose of setting the number of stages is that when the controller 11 grasps the number of stages of the creel device 1, it is determined that there is an abnormality in comparison with the set value of the number of threads and the count value in the above-described setting of the number of threads (position). This is so that the location can be easily found when it is done.

Specifically, in the process of setting the number of yarns and the position, each controller 11 outputs a pulse train signal corresponding to the number of valid yarn breakage sensors 9 in the corresponding row. Make a comparison. And only when both correspond, for example, the display lamp 21 attached to the controller 11 is lit.

In this case, in the above-described case, the five rows far from the winding device 7 on the creel device 1 have no yarn feeder 2 or only a part thereof, so that the corresponding controller 16 The display lamp 21 is not turned on. However, the display lamps 21 in other columns should be lit.

If the set value of the number of yarns (number of yarn feeders 2) does not match the count value as a result of the above-described detection of the number of yarns, an abnormality (yarn feeder 2) is detected in any one of the yarn feeders 2 or the yarn breakage sensor 9. It is determined that the device has also been forgotten). In this case, since the display lamp 21 is not turned on in that row, if the row in which the yarn supplying body 2 is present and the display lamp 21 of the controller 16 is not turned on is checked, the abnormal portion can be easily found. Can look into.

[Step number setting flow]
FIG. 10 shows an operation sequence for setting the number of stages. In FIG. 10, after starting the stage number setting program (START), the central processing unit 12 first determines whether or not the initial address setting has been normally completed (step 201). If the address setting is not completed (NO), the program is not executed and the process is terminated (END). If the address setting is normally completed (YES), the process proceeds to the next step, and the controller 11 determines the signal output state on the two second transmission lines 14 (step 202). ). If it is determined that the signal output states of the two second transmission lines 14 are not in the state indicating the stage number setting mode (NO), the program ends with the stage number setting mode turned OFF (step 210).

As a result of the determination in step 202, when it is determined that the signal output state on the two second transmission lines 14 and 14 is the state (YES) indicating the stage number setting mode, each controller 16 is set to the stage number setting mode ON. Then, each controller 11 clears the number of stages stored in the storage unit 17 so far and resets the counter of the control unit 16 (step 204), and the central processing unit 12 through the first transmission line 13. Or it prepares for the output of the signal from the controller 11 of the upstream side.

Next, a signal including information corresponding to the number of stages is output from the central processing unit 12 to the # 1 controller 11 on the most upstream side via the first transmission line 13. In this example, a signal including information corresponding to the number of stages is a stage number pulse command including a number of pulses that matches the number of stages. That is, as described above, when the number of stages is 10, the number of pulses of the stage number pulse command is 10 pulses. The number of stages is preset in the central processing unit 12 by the operator.

The controller 11 of # 1 determines whether or not a stage number pulse command is input (205). In other words, if the detection of the rising edge of the pulse has not been detected (NO), the standby state is continued to prepare for the pulse train signal from the central processing unit 12. When the detection of the rising edge of the pulse is confirmed (YES), +1 is added to the count value of the counter of the control unit 16 in the next step (step 206).

Next, as in the address setting, an operation for confirming the number of pulses included in the output pulse train signal is performed. Specifically, it is determined whether or not a predetermined time has elapsed from the time when the rising edge of the pulse is detected (step 207). If the predetermined time has not elapsed (NO), the rising edge of the pulse is detected again. It is confirmed whether or not (step 208).

If it is determined in step 207 that the predetermined time has elapsed (YES), the counting of the number of pulses included in the stage number pulse command has been completed. Therefore, the control unit 16 counts the previous count value (+10 ) To the storage unit 17, and the storage unit 17 stores and holds the count value output from the control unit 16 as the number of stages in the column (step 209). As a result, the maximum number of rows in the column corresponding to the controller 11 is set. Note that the “number of stages” here is the number of yarn supplying bodies 2 that can be mounted in each row in the creel device 1, and is different from the number of yarn supplying bodies 2 that are actually set.

Further, the controller 11 of # 1 performs a first transmission from the output port 18 of a signal including the same number of pulses as the number of stages set therein, that is, a pulse signal having the same number of pulses as the input pulse train signal. The data is output to the input port 15 of the downstream # 2 controller 11 via the line 13 (step 210).

Each downstream controller 11 after the # 2 controller 11 stores and holds the number of stages in each storage unit according to the input stage number pulse command, as well as the above-described # 1 controller 11, and at the downstream side. A pulse train signal (stage number pulse command) including the same number of pulses is output to the controller 11. In this way, the number of stages is automatically set for each controller 11 sequentially from the upstream side to the downstream side.

The #N controller 11 on the most downstream side outputs a pulse train signal including the number of pulses equal to the number of stages to the central processing unit 12 through the first transmission line 13 by the above processing. The central processing unit 12 determines that the number of stages has been normally set for each controller 11 by inputting this pulse train signal within a predetermined time, and determines the output state of the signal in the second transmission line 14 as the number of stages. Assume that the setting mode is OFF, that is, corresponds to another mode (step 211).

The present invention is not limited to the so-called V-shaped creel device 1 shown in FIG. In the example of FIG. 1, the warp row is divided and arranged in two yarn feeder frames 3b, but in this case, the parallel connection of the controller 11 by the first transmission line 13 is connected to the yarn feeder frame. The central processing unit 12 can be provided for each yarn feeder frame 3b. That is, the two first transmission lines 13 are connected to the central processing unit 12, and each first transmission line 13 connects the controllers 11 corresponding to one yarn feeder frame 3b in series. Alternatively, all of the controllers 11 corresponding to each yarn feeder row may be connected in series by the first transmission line 13. In this case, connection is made in units of the yarn feeder frame 3b so that the controller 11 corresponding to the yarn feeder row at the end of one yarn feeder frame 3b and the feed of the end of the other yarn feeder frame 3b are connected. The controller 11 corresponding to the yarn body row may be connected, or may be connected in the order corresponding to the position of the yarn body row irrespective of the yarn body frame 3b.
