Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weaving machine operating method and a weaving machine operating apparatus for starting a steady operation after displacing the cloth fell position to a desired position when the operation of the loom is started.

[0002]

2. Description of the Related Art When a cause of a stop occurs in a loom, for example, as shown in FIGS. 1 to 3, braking is performed after the cause of the stop and the loom is stopped in the cycle next to the cycle in which the cause of stop occurs. Then, a waiting method of the loom is adopted in which the main shaft angle is reversed to a predetermined value and the weaving step due to the warp elongation due to the warp opening state is suppressed. Then, after the stop cause repair work is performed, the loom is restarted. Typical methods for starting a loom when the loom is restarted after the cause of the stop is repaired are as follows (1) a normal starting method and (2) a starting method with reverse rotation (Japanese Patent Laid-Open No. 61-124651). ,
(3) The 60 ° start method is known. The outline of each activation method is as follows.

(1) Ordinary start-up method: This ordinary start-up method is a very ordinary start-up method for a general loom.
As shown in, the loom is stopped and waiting at the main spindle angle of 300 °, which is the warp closing state of the stop cause cycle.
Depending on the cause of the stop, for example, if it is a non-weft insertion error such as warp breakage, it is activated by the activation method A11, and if it is a weft insertion error, it is activated by the activation method A12.

In the starting method A11, since the cause of the stop is not the weft insertion error, the weft inserted immediately before the stop is properly inserted and does not need to be removed. Therefore, when the operator presses the operation button after repairing the cause such as warp breakage, the operation shifts to the normal operation as it is, and the weft insertion is started corresponding to the rotation of the main shaft. The starting angle of the main shaft at this time is 300 °.

In the starting method A12, since the cause of the stop is a weft insertion error, it is necessary to remove the weft inserted into the weft just before the stop. Therefore, the operator operates the reverse rotation button to reverse the spindle angle of 180 °, which is close to the warp maximum opening of the cycle causing stop, to remove and repair the defective weft causing the stop, and then to operate the button again. Thus, the main shaft angle in the warp closing state in the cycle before the stop cause cycle is reversed to 300 °. After that, when the operation button is pressed, the operation shifts to the normal operation as it is, and the weft insertion is started corresponding to the rotation of the spindle.

(2) Starting method with reverse rotation
No. 1-124651); this starting method is also called reverse rotation start or idle start, and it is to eliminate the beating force shortage at the time of starting the loom as a measure for preventing the weft.
As shown in FIG. 2, the loom stops and waits at a main spindle angle of 300 °, which is the warp closing state of the stop cause cycle, and if there is a non-weft insertion error according to the cause of the stop, the starting method A21 is used. If the weft insertion error has occurred, it is activated by the activation method A22.

In the starting method A21, since the cause of the stop is not the weft insertion error, the weft inserted immediately before the stop is properly inserted and does not need to be removed. Therefore, when the operator presses the operation button after repairing the cause of stop such as warp breakage, the first angle (for example, 120 °) in the stop cause cycle or the first angle in the cycle before this is generated. After reversing, the normal operation is started from the reverse position without weft insertion, and the weft insertion is started when the first position to be wefted is reached. At this time, the starting angle of the spindle is set to 120 ° or any other angle.

In the starting method A22, since the cause of the stop is a weft insertion error, the weft inserted immediately before the stop must be removed. Therefore, the operator operates the reverse rotation button to reverse the spindle angle of 180 °, which is close to the warp maximum opening of the cycle causing stop, to remove and repair the defective weft causing the stop, and then to operate the button again. Thus, the main shaft angle is reversed to 300 °, which is the warp closing state in the cycle before the stop cause cycle. After that, when the operation button is pressed, the steady operation is performed from the reverse position after reversing to the first angle (for example, 120 °) in the cycle causing the stop or the first angle in the cycle earlier than this. Instead, start with a blank shot, and start wefting when the first position for wefting is reached. It should be noted that it is possible to arbitrarily set the above-described reverse rotation position, that is, how many cycles before the stop cause generation cycle the reverse rotation is performed, and the first angle is not limited to 120 ° and is arbitrarily set.

(3) 60 ° start method: This starting method is a measure for preventing the occurrence of twill pillows in the twill structure such as 2/1. This is a starting method with the number of hits suppressed as much as possible. As shown in FIG. 3, the loom stops and stands by at a spindle angle of 60 ° in the cycle following the cycle causing the stop, and if there is a non-weft insertion error depending on the cause of the stop, the loom is started by the starting method A31. , If weft insertion error, start method A
41 or the activation method A42.

In the starting method A31, since the cause of the stop is not the weft insertion error, the weft inserted immediately before the stop is properly inserted and does not need to be removed. Therefore, the worker
After repairing the cause such as warp break, press the operation button,
From the standby position, weft insertion is performed and normal operation begins.

In the starting method A41, since the cause of the stop is a weft insertion error, the weft inserted immediately before the stop must be removed. Therefore, the operator operates the reverse rotation button to reverse the spindle angle of 180 °, which is close to the warp maximum opening of the cycle causing stop, to remove and repair the defective weft causing the stop, and then to operate the button again. Thus, the main shaft angle of the stop cause generation cycle is reversed up to 60 °. After that, when the operation button is pressed, normal operation starts while wefting is started from this spindle angle.

Also, instead of the above-mentioned starting method A41, a starting method 42 can be adopted. The starting method 42 corresponds to the case where the cause of the stop is a weft insertion error.
Similar to No. 41, the weft thread inserted just before the stop needs to be removed. Therefore, the operator operates the reverse rotation button to reverse the spindle angle to 180 °, which is a state close to the maximum warp opening in the stop cause cycle. Then, after removing the defective weft caused by the stop and repairing it, press the one weft insertion button to insert one weft, and then press the operation button to correct it to 300 ° within the cycle causing the stop. Turn over and start normal operation with weft insertion from that position.

In the starting methods A41 and A42, the starting angle of the main shaft is 60 °, which is a position where the opening amount is stable in both upper and lower directions and the weft insertion can be started immediately.
It is not limited to 60 ° as long as this condition is satisfied.

It should be noted that in FIG. 1 to FIG. 3, the starting method A1
1, A12, A21, A22, A31, A41, A42
Indicates a unique number, which will be used later when specifying the starting method (starting program) in the description of the present invention. By the way, there are startup methods (startup programs) other than those shown in FIGS. 1 to 3, and these are A11, A12, A21,
After A22, A31, A41, A42, ..., An
It is represented as n.

The storage device 33 stores the program of the starting method based on the operating method of the loom of the present invention, and also the loom 1
The data necessary for the start control of the above is stored and these are input to the main controller 31 when necessary. In addition, the setting device 34 sets the control start angle, the reverse rotation stop angle, the presence or absence of weft insertion, the steady operation start angle, and other control device data as start control data, and inputs the data to the main controller 31. .

In the setting stage of the control of the loom 1 in FIG. 5, the selector 32 is operated by the operator's selection operation or by the automatic selection operation according to the cause of the stop of the loom 1.
A starting method at the time of starting the operation of the loom 1 is specified. At this time, the selector 32 sends a selection signal of a start program corresponding to the specified start method to the main controller 31 and the displacement amount setter 35. The main controller 31 reads out a boot program corresponding to the specified boot method from the storage device 33,
Prepare to execute the read startup program.

Further, the displacement amount setter 35 sends out a signal of the displacement amount of the cloth fell position corresponding to the starting program of the starting method specified based on the storage form of the displacement amount of the cloth fell position in FIG. It is sent to the cloth fell position controller 40 on the side and the cloth fell position controller 41 on the winding side. Here, the cloth fell position controller 40 on the sending side and the cloth fell position controller 41 on the winding side prepare for the subsequent operation start based on the received signal of the displacement amount of the cloth fell position.

For example, consider a case where the above-mentioned 60 ° start method is used as the starting method for eliminating the twill pillow and the starting method is selected according to the cause of the stop. That is, the start method A31 is stored in the storage device 33 in response to the non-weft insertion error and the start method A41 is stored in the storage device 33 in response to the weft insertion error. Also, the displacement amounts F31, R31 and F41 at the cloth fell position corresponding to the starting methods A31 and A41,
R41 is set in the setter 35, respectively.

When the loom 1 causes a stop of a non-weft insertion error such as a warp break during operation, the main controller 31
Stops the loom 1 according to a standby method stored in advance. Specifically, braking is started immediately after the cause of the stop is generated, and the loom 1 is stopped in the cycle next to the cycle where the cause of the stop is generated. In order to avoid unnecessary beating, 6
Reverses to 0 ° and enters the standby state. On the other hand, a stop cause signal is input to the selector 32, and the selector 31 outputs a selection signal for selecting the starting method A31 corresponding to the input, to the main controller 31 and the cloth fell position controller 40. , 41.

When the arriving operator repairs the warp break and turns on the operation button 36 and sends an operation signal to the main controller 31 as an operation operation signal, the main controller 31 activates the drive motor 26 by the spindle controller 29. Before the operation, that is, in the period of preparation for operation, an operation preparation signal is sent to the cloth fell position controller 40 on the sending side and the cloth fell position controller 41 on the winding side. During this operation preparation period, the cloth fell position controller 40 on the sending side and the cloth fell position controller 41 on the winding side are provided.
Drive the delivery motor 16 as the cloth fell position displacing means and the winding motor 19 as the cloth fell position displacing means based on the signal of the displacement amount of the cloth fell position, respectively. 13 is rotated in a predetermined direction, and the position of the cloth fell 9 corresponding to the selected starting method A31 is displaced by the displacement amounts F31 and R31.

When the position of the cloth fell 9 is displaced by the amount of displacement during the operation preparation period, the cloth fell position controller 4 on the sending side
The 0 and the take-up side cloth fell position controllers 41 stop the driving of the feed motor 16 and the take-up motor 19, respectively.

After the lapse of the operation preparation period, the main controller 31 sends an operation signal to the main spindle controller 29 to start the drive motor 26 by the main spindle controller 29 based on the start program of the specified starting method. Then, the steady operation is started. When shifting to this steady operation, the delivery controller 15
Drives the feed motor 16 by tension control, and the take-up controller 18 takes in the rotation signal from the rotation detector 23 and drives the take-up motor 19.

On the other hand, when a weft insertion error occurs during operation, the main controller 31 reverses to 60 ° of the stopped cycle according to the stored standby method similarly to the former, and enters the standby state. On the other hand, the selector 31 sends to the main controller 31 and the cloth fell position controllers 40 and 41 a selection signal for selecting the starting method A41 in response to the input of the cause of the stop.

When the operator arrives, the reverse button 36 is pressed to remove the weft insertion error yarn. When a reverse rotation signal is sent to the main controller 31 as a reverse rotation operation signal, the main controller 31 reverses the rotation up to 180 ° in the stop cause cycle according to the startup program A41. After that, when the operator removes the weft insertion error yarn and presses the reverse rotation button 36 again, the reverse rotation signal is input to the main controller 31 again, and the main controller 31 follows the program at 60 ° of the cycle of cause of stoppage. Stop. Then, when the operator presses the operation button 36, the main controller 31 causes the cloth fell position controller 40 on the sending side and the cloth fell position controller 41 on the winding side before the steady operation is started, that is, during the operation preparation period. Send a driving preparation signal to. Therefore, the controller 40 and the controller 41 drive the feed motor 16 and the winding motor 9 in accordance with the set displacement amounts F41 and R41 of the cloth fell position corresponding to the start method selection signal to change the cloth fell position. Displace.

The above embodiment can be modified as follows. In the above-mentioned start-up program A41, the series of spindle drive steps from the repair of the cause of the stop until the start of the steady operation is step-processed by the push button operation, but it may be automatically performed after the first push button operation. Further, the timing of displacing the cloth fell position, in other words, the output timing of the start preparation signal is not limited to immediately before the start of steady operation, and may be performed at any time between the standby state and the start of steady operation. Good. The above is the same for other startup programs.

Regarding the start program to be used,
Although the activation methods A31 and A41 are selected, the invention is not limited to this selection, and the activation methods (1), (2), and (3) can be arbitrarily selected from different classifications. For example, two different classifications such as the starting method A11 and the starting method A31, and the starting methods A21 and A31 may be selected as the stopping cause and the weaving conditions such as the fabric and the shot density. Further, regarding the starting methods (2) and (3), that is, the starting program (starting program) having a different first or second main spindle angle is selected for the starting program accompanied by inching or reverse rotation to the first or second main spindle angle. You can also In this way, the displacement amount of the cloth fell position may be set corresponding to the selected starting method (starting program).

According to such a start-up method, the amount of displacement of the cloth fell position that suits each start-up method (start-up program) is set during the operation preparation period, and after that, the steady operation is started. Even if the method (startup program) is changed, the weft can be reliably prevented.

By the way, the specific example of FIG. 5 is a preferred embodiment based on the operating method of the loom of the present invention.
The feeding motor 16 for the warp yarn 2 and the winding motor 19 for the woven fabric 8 are simultaneously driven. However, the operating method of the loom of the present invention is at least the delivery motor 16 for the warp yarns 2.
Alternatively, it can be carried out by driving the winding motor 19 for the woven cloth 8.

Next, FIG. 7 shows a specific example of the feed-out controller 15 and the cloth-feed position controller 40 on the send-out side. In FIG. 7, during the operation preparation period, the displacement amount setter 35 outputs the signal of the displacement amount of the cloth fell position corresponding to the starting program of the selected starting method based on the stored contents of FIG. It is sent to the displacement amount signal generator 53 in the cloth fell position controller 40. The displacement amount signal generator 53 corrects the displacement amount of the cloth fell position by the winding diameter when the operation preparation signal and the start method selection signal are input, and, if necessary, stops the stop time from the stop time calculator 54 ( (Elapsed) time signal is input, the displacement amount of the cloth fell position is corrected by the stop (elapsed) time, an appropriate displacement amount of the cloth fell 9 is set, and the signal of the appropriate displacement amount of the cloth fell position is corrected. It is fed to the plus side input end of the reverse counter 55.

Therefore, the speed command signal as the output of the forward / reverse counter 55 is sent to the drive amplifier 52 via the contact 49 and the addition point 51 which are in the ON state during the preparation for operation. The contact 49 is in the ON state during the operation preparation period before shifting to the steady operation. The drive amplifier 52 drives the feed motor 16 by the signal of the speed command at this time, and moves the position of the cloth fell 9 by an appropriate displacement amount of the cloth fell.

The rotation of the feed motor 16 is detected by the rotation detector 56, and is sent to the minus side input end of the forward / reverse counter 55 as a rotation amount signal. Therefore, when the feed motor 16 rotates by a predetermined amount of position displacement of the cloth fell, the output of the forward / reverse counter 55 (speed command signal) becomes zero, and the drive amplifier 52 stops driving the feed motor 16. .

When the operation preparation period elapses and the operation shifts to steady operation, the delivery controller 15 performs tension control on the warp yarns 2 to deliver the warp yarns 2. For example, the tension is detected at the position 4 of the back roll. The tension of the warp yarn 2 is detected by the device 28. The detected tension is added as a negative signal to the target tension signal set by the target tension setter 42 at the addition point 43, and is sent to the tension controller 44 as a tension deviation. Here, the tension controller 44 is
PID control is performed to generate a speed command signal proportional to the tension deviation and output it to the addition point 45.

On the other hand, the basic speed generator 46 generates a basic speed command signal based on the weaving conditions such as the rotation speed of the loom 1 and the weft driving density, and outputs it to the addition point 45. Therefore, the winding diameter corrector 47 receives the signal of the sum of the speed command proportional to the tension deviation and the basic speed command, and the winding signal of the warp yarn 2 detected by the winding diameter detector 27 is added to this sum signal. Based on the above, necessary correction calculation [(speed command proportional to tension deviation + basic speed command) / winding diameter] is performed to generate the final speed command signal, and the contact 4
8 and the addition point 51, and then sends to the drive amplifier 52. Contact point 4
8 is turned on by the operation signal. Therefore, during the steady operation of the loom 1, the drive amplifier 52 drives the feed motor 16 by the final speed command signal.

Next, FIG. 8 shows a specific example of the winding controller 18 and the cloth fell position controller 41 on the winding side. In FIG. 8, during the operation preparation period before steady operation,
The displacement amount setter 35 sends a signal of the cloth fell position displacement amount corresponding to the starting program of the selected starting method to the displacement amount signal generator 59 in the cloth fell position controller 41 on the winding side. The displacement amount signal generator 59, when the operation preparation signal and the start-up method selection signal are input, outputs a displacement amount signal at the cloth fell position suitable for the selected start-up method to the plus / minus counter 55 of the forward / reverse counter 55 via the addition point 58. Side input end.

The forward / reverse counter 60 includes the displacement amount signal generator 5
The signal of the displacement amount of the cloth fell position from 9 is input, and an output for winding is generated and sent to the drive amplifier 61. Therefore, the drive amplifier 61 moves the cloth fell 9 by driving the winding motor 19 by an amount corresponding to the displacement amount of the cloth fell position suitable for the selected starting method during the preparation for starting. . The basic speed generator 57 does not output the basic speed signal during the operation preparation period.

The rotation of the winding motor 19 is detected by the rotation detector 62, and is sent to the minus side input end of the forward / reverse counter 60 as a rotation amount signal. Therefore, when the winding motor 19 rotates by a predetermined displacement amount at the cloth fell position, the output of the forward / reverse counter 60 (speed command signal) becomes zero, and the drive amplifier 61 drives the winding motor 19. Stop. As described above, the cloth fell position controller 41 on the take-up side is selected by driving the take-up motor 19 by an amount corresponding to an appropriate displacement amount of the cloth fell position during the operation preparation period. The cloth fell 9 is moved to a position suitable for the starting method.

When the operation preparation period elapses and the operation shifts to steady operation, the basic speed generator 57 in the winding controller 18
Takes in not only the rotation (speed) signal of the main shaft 23 from the rotation detector 23, but also a driving density signal and the like to generate a basic speed signal for winding. It is being sent to the positive input end.
At this time, the displacement amount signal generator 59 does not generate an output. The forward / reverse counter 60 includes a basic speed generator 57.
The signal for the basic speed from the input terminal is used as an input to generate an output for winding, which is sent to the drive amplifier 61. Therefore, the drive amplifier 61 winds the woven fabric 8 following the progress of weaving by driving the winding motor 19 during steady operation.

By the way, the displacement amount of the cloth fell position is set corresponding to the starting method (starting program). Specifically, (a) in order to reflect the warp shed condition until steady operation, In order to reflect the stop angle due to jogging or reverse rotation, the angle to start steady operation, and (b) the cause of stoppage,
Information on whether or not the weft yarn woven immediately before is removed at the time of repairing the cause of the stop, and information on whether or not the weft yarn is put in before the steady operation thereafter, (c) Reed In order to reflect the beating condition, the presence or absence of repulsion due to inching or reversal until steady operation, the number of repulsions with repulsion, and (d) warp elongation (movement amount of the front position) with the passage of time. ) Is set from the standpoint of, for example, the stop time or the time from the stop to the normal operation.

The displacement amount signal generators 53 and 59 use the circuits shown in FIGS. 8 and 9 described later in order to set the displacement amount of the cloth fell position from the above viewpoint, or these are taken into consideration. It is configured using a circuit that generates a displacement amount signal of an empirical value. Further, the displacement amount of the cloth fell position can be either a displacement to the winding side (feed) or a displacement to the delivery side (return), and further, it is possible.
As described in Japanese Patent No. 3749, warp 2 and reed 6
In consideration of the frictional resistance with the heddle 5 and the heddle 5 or the like, it is also possible to drive by combining the displacement to the winding side (feed) and the displacement to the delivery side (return) with time.

FIG. 9 shows the displacement signal generator 5 at the cloth fell position.
3 or a specific example of the displacement amount signal generator 59 is shown.
In FIG. 9, the selector 63 receives the start method selection signal,
One of the plurality of signal generators 64 provided corresponding to the plurality of starting methods is selected and output to the multiplier 65. here,
When receiving the operation preparation signal, the multiplier 65 performs displacement (calculation) of the target displacement amount of the cloth fell position set in the displacement amount setter 35 and the signal from the selected signal generator 64. Generate a quantity signal. According to this, it is not necessary to set the cloth fell displacement amount for each starting method, and the setting work is simplified.

Next, FIG. 10 shows another specific example of the displacement amount signal generator 53 or the displacement amount signal generator 59 at the cloth fell position. In FIG. 10, the parameter generator 66 receives the selection signal of the starting method, and from the above viewpoint, (a) data of the angle at which the operation stops due to inching or reverse rotation, data of the angle at which the steady operation is started, and (b) cause of stoppage. Data of whether the weft yarn woven immediately before is removed at the time of restoration of No. 3, and data of whether weft insertion is performed thereafter until reaching steady operation, (c) steady operation Data of the number of beatings is sent to the function generator 67 when the beating is caused by inching and reversing. In addition to the data of (a), (b), and (c) above, the function generator 67 uses the remaining 1
From one viewpoint (d) stoppage time or the time from the stop to the start of steady operation, data from the time generator 68 is fetched,
With respect to these data, a function signal that is proportional, inversely proportional, exponentially increasing or decreasing, or quadratic or n-dimensionally changing is generated and output to the multiplier 69. Here, the multiplier 69, when receiving the operation preparation signal, calculates (multiplies) the target cloth fell movement amount set in the displacement amount setter 35 and the signal from the selected function generator 67. Generate a displacement amount signal. This also eliminates the need to set the amount of displacement of the cloth fell position for each starting method, and simplifies the setting work using complicated data.

As described above, the cloth fell position displacing means need not be the feeding movement of the warp threads 2 or the winding movement of the woven cloth 8 but only one of them. Also,
The cloth fell position displacing means is configured to feed the warp yarn 2 and to move the woven cloth 8
In addition to the means involved in the winding movement of the cloth, the cloth cloth may be configured to directly change the cloth fell position, for example, a driving mechanism in the front-rear direction of the back roll 4, a cloth moving mechanism of the pile loom, or the like.
