Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for activating a loom set in a leveling state by unifying operation procedures regardless of the cause of stop.

[0002]

2. Description of the Related Art JP-A-4-91257 and JP-A-4
Japanese Patent Publication No. -41735 and Japanese Patent Publication No. 61-22049 disclose that the opening pattern of the electronic dobby device is changed to a plain weave pattern and the loom is moved to the closing angle in order to realize the leveling state. According to these techniques, since the loom is on standby in the leveling state while the loom is stopped, there is an effect that the warp spread during the stop can be suppressed, and the occurrence of a weft bar due to this can be prevented.

[0003]

However, on the other hand, there are the following problems. The worker who arrives at the loom waiting in the leveling state operates the return button, reverse rotation button, operation button, etc. for leveling release to release the leveling state and perform necessary repairs such as weft repair and warp repair. I was working and was starting the loom. In this case, since the operation procedure differs depending on the cause of the stop, the worker must determine the cause of the stop and operate the loom according to the required procedure. However, since there are many operation buttons and the operation procedure differs depending on the cause of the stop, the operator tends to make an erroneous operation due to a mistake in judgment. This caused a weaving step. Under such circumstances, an operation procedure that does not require intervention of the operator's judgment is desired.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to unify the procedure of the starting operation regardless of the cause of the stop of the loom, and prevent the operator from making a mistake and the occurrence of a weaving bar.

[0005]

In view of the above object, the present invention is a method of setting a shed device in a leveling state and waiting while a loom is stopped, and operates a button for canceling the leveling regardless of the cause of the stop. Afterward, paying attention to the common operation procedure of operating the operation button for starting the loom, for example, after canceling the leveling by operating the return button, it is determined whether the cause of the stop is weft stop or other After a proper sequence is selected and executed according to the cause of the stop other than the stop, the loom is set in a state in which it can be started according to the operation of the operation button. Specifically, it can be summarized in the following three inventions.

Let
After that, when the operation button is operated, the sequence for automatically starting the loom and then starting the loom is executed.For causes other than the weft cause, after releasing the leveling state, the loom is started to the starting position. Automatically rotate until
After that, when the operation button is operated, the sequence for activating the loom is executed as it is.

The starting method of the second invention is provided with a return button for returning from the leveling state to the normal opening state in a system in which the shedding device is set to the leveling state and the loom is on standby while the loom is stopped. , First, when the return button is operated, it is determined whether the cause of the stop at that time is the weft cause or another cause, and if it is the weft cause, the loom is automatically rotated to the outlet opening position after the leveling state is released. The sequence is executed, and when the cause is other than the weft cause, the sequence for canceling the leveling state is executed, and after these executions, when the operation button is operated, the loom is automatically rotated to the start position, and then the loom To start.

According to a third aspect of the present invention, in the method of setting the shedding device in the leveling state and waiting the loom while the loom is stopped, the operation button is operated when returning from the leveling state to the normal shed state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the relationship between the main parts of a loom 1 and a control device 2. On the input side, the control device 2 has a weft-causing sensor 3 such as a weft-insertion feeler, a trans-cause sensor 4 such as a dropper device, other stop-causing sensors 5, an operation button (switch) 6, a stop button (switch) 7, a leveling device. 10
Setting button (switch) 8, return button (switch) for
9. In addition to the rotation detector 18 connected to the main motor 15, the electronic dobby device 19 and the weft automatic restoration device 22 are connected, and at the output side, the electronic dobby device 19, the beating control device 11, the weft insertion device. Control device 12, delivery control device 1
3, the winding control device 14, the rotation control unit 16 of the main motor 15 connected to the main shaft 17, the braking device 21, the weft automatic restoration device 22, and the like. Although not shown, on the input side, other operation buttons such as a reverse rotation button and a forward rotation button are also connected.

The electronic dobby device 19 is provided with a large number of solenoids driven by a memory and electronic circuits as described in, for example, Japanese Patent Laid-Open No. 4-91257, and has a preset opening pattern. The solenoid group is operated based on the program to drive the opening device 20 accordingly. The opening device 20 vertically moves the heald frame in accordance with the operating state of the solenoid group to realize a desired opening pattern. Normally, the output of the electronic dobby device 19 is given to the shedding device 20 at a timing that precedes the actual shedding pattern realized by one cycle, centering on the warp cross timing near the warp closing period.

Next, FIGS. 2, 3 and 4 show flow charts of a method for starting a loom corresponding to the first, second and third inventions, respectively. These start-up programs are stored in advance inside the control device 2 and are started with the leveling state as the start condition.

In these start-up programs, the control device 2 rotates the main motor 15 and drives the main shaft 17 when the operation command from the operation button 6 is input.
In synchronization with this, the reeding movement, the weft insertion movement, the feeding movement and the winding movement are executed to weave.

When the weft insertion failure occurs as the weft cause or the warp breakage occurs as the warp cause while the loom 1 is in operation, the weft cause sensor 3 or the warp cause sensor 4 outputs a signal of a stop command and the control device 2 is operated. Send to. Of course, when the cause of stop other than this is detected by the stop cause sensor 5,
Alternatively, even when the operator sets the stop button 7 to the on state, the stop command is given to the control device 2.

At this time, the control device 2 prevents the weft insertion by the weft insertion control device 12 in the cycle next to the cycle in which the cause of the stop occurs, and activates the braking device 21 of the main shaft 17,
After stopping at about 260 degrees and giving a leveling command to the leveling device 10, the loom 1 (spindle 17) is automatically reversed to about 300 degrees, and the leveling state is set at that position to stand by. Note that, in order to realize the leveling state, a known method as described in the section of the related art can be adopted, but a specific method in this embodiment is
It will be described later.

After that, when the worker arrives, necessary repairs such as the weft yarn and the warp yarn are performed based on the starting method of the present invention. When the automatic weft repair device 22 is attached, the control device 2 reverses the loom 1 up to about 180 degrees of the weft-causing cycle without operating the leveling device 10, and the automatic weft repair device 22 is operated there. To operate. If the restoration is successful, the loom 1 is started up as it is after being reversed up to about 300 degrees. When the restoration is unsuccessful, the control device 2 gives a leveling command to the leveling device 10, and then automatically causes the loom 1 to reversely or normally rotate up to about 300 degrees, set the leveling state and wait. Also in this case, when the worker arrives after that, the weft is repaired based on the starting method of the present invention.

In the starting method of FIG. 2, the program is started on condition that the opening device 20 is set to the leveling state, and first, it is judged whether or not the return button 9 is set to the ON state. The leveling device 10 releases the leveling state when the setting operation is performed in the ON state. Next, it is judged whether the cause of the stop is a weft cause or another cause, and a sequence corresponding to the cause of the stop is selected. Note that the leveling state can be released by a known method. For example, it can be realized by returning the previously changed opening pattern for leveling (for example, a plain weave pattern) to a normal opening pattern for weaving and rotating the loom 1 by a predetermined amount.

When the cause of the stop is the weft cause, the loom 1 is moved to the exit position of the cycle (for example, 1 when the defective weft exists).
Automatically rotate to (about 80 degrees) and stop there. When the operator repairs the weft and then the operation button 6 is turned on, the starting position (for example, near 300 degrees)
After the loom 1 is automatically rotated and stopped, the loom 1 is automatically started, and a series of starting operations is completed. Cause of stop = latitude? When the cause of the stop is other than the weft cause in the step of 1, the loom 1 is automatically rotated to the start position and stopped. When the cause of the stop is due to the cause, the repair is performed by the worker at this stop position. After that, when the operation button 6 is set to the ON state, the loom 1 is started as it is, and the series of operations is ended. The warp repair may be performed when the loom 1 is in the leveling state immediately after the worker arrives. This is because, in general, warp repair is performed by setting the warp yarn in the closed state, and thus the warp repair can be performed at an arbitrary time when the warp yarn is in the closed state in the course of the series of operations described above.

According to this start-up method, regardless of the cause of the stop, the start-up operation is always performed after the return button 9 is operated, and then the operation button 6 is operated. It is possible to prevent a weaving step from occurring due to a mistake in judgment. The stop due to the weft cause includes not only the stop due to the weft insertion failure but also the case where the automatic weft repair device 22 is attached and the repair of the device fails.

Next, in the starting method of FIG. 3, when the cause of the stop is the weft cause, the starting operation is performed by the same operation procedure as the operation of FIG. However, the cause of the stop = latitude? 2), when the cause of the stop is a cause other than the weft cause, unlike the case of FIG. 2, the step of stopping the starting position is not performed, and immediately shifts to the determination of the ON state of the operation button 6, and the following program is executed. I will do it. In this embodiment, when the cause of the stop is the cause, the warp repair is preferably performed when the loom 1 is in the leveling state. This is because, unlike the starting method shown in FIG. 2, when the operation button 6 is operated, the loom 1 is located at the outlet opening position (near 180 degrees) and it is difficult to perform warp repair.

In this start-up method, in addition to the effect of FIG. 2, the sequence when the operation button 6 is operated is the same regardless of the cause of the stop, so unexpected operation causes
It is preferable from the point of view of safety, since there is no danger of workers being confused.

In the starting method shown in FIG. 4, the operation of the return button 9 for canceling the leveling in the starting method is changed to operate the operation button 6 instead. is there. That is, the return button 9 is omitted,
The function of the return button 9 is also used by the operation button 6. When the operation button 6 is operated, the leveling state is released and the cause of the stop = weft? When the cause of the stop is other than the weft cause in the step, the process directly moves to the step of stopping the loom 1 at the starting position, and when the cause of the stop is the weft cause, the operation button 6 is turned off after stopping at the outlet opening position. Judgment is made,
After confirming that the operation button 6 has been turned off once and then determining whether the operation button 6 is turned on, the process proceeds to the step of stopping the starting position. In addition, in this embodiment, when the cause of the stop is the cause, the warp repair is performed when the loom 1 is in the leveling state. This is because the loom 1 is automatically started after the operation button 6 is operated to cancel the leveling.

According to this starting method, the leveling can be released and the starting operation can be performed by a unified operating procedure in which only the operation button 6 is always operated regardless of the cause of the stop. Therefore, it is possible to prevent the occurrence of a weaving step.

As described above, in the start-up method shown in FIGS. 2, 3 and 5, the cause of stop = latitude? All of the determinations are made after the leveling is released, but instead of this, the determination may be made when the return button 9 or the operation button 6 is operated to release the leveling.

[0024]

[Specific Example of Startup Sequence] FIGS. 5, 6 and 7 show specific examples of the startup sequence according to the cause of the stop in the above-described startup method of FIG. In each of these figures, the diagonal lattice-shaped figure in the upper part is a replica of the actual shed pattern of the warp, and the symbols ○, ×, and △ in the shed indicate normal weft insertion, weft stop, and weft stop, respectively. This indicates the occurrence of the cause of warping and the prohibition of weft insertion.

In these starting sequences, the loom 1
Is stopped due to the occurrence of the stop cause, the loom 1 is automatically set to the leveling state, and the arrival of the worker is waited in this leveling state. Therefore, after the loom 1 is stopped, the solenoid selection output of the electronic dobby device 19 is reversed, and then the loom 1 is automatically reversed to set the leveling state within one revolution of the loom 1. This inversion pattern will be described in detail with reference to FIG. The return operation for returning from the leveling state to the normal opening state, that is, the release of the leveling state is performed by turning on the return button 9.

When it is necessary to remove the defective weft yarn due to the weft cause, the stop position at the time of reverse rotation is the exit opening position near 180 degrees, and when the cause is other than the weft cause, the stop position is 30.
It is a closed position near 0 degree.

In these sequences, the idle driving is adopted for the purpose of compensating for the lack of repulsive force at the time of starting. It should be noted that a specific example of this idle driving will be described in detail later. When the operation button 6 is turned on, if the stop angle is 180 degrees, automatic reverse rotation is performed up to the start angle of 300 degrees, and if the stop angle is 300 degrees, the step of the electronic dobby device 19 is immediately performed. Is returned by a value corresponding to the number N of times of idle driving performed at the time of starting.

The return operation of this step is realized by the control device 2 to the electronic dobby device 19 by a serial method of sequentially applying a required number of pulses or by a necessary bit pattern by a parallel method. After that, the feeding operation and the winding operation are stopped by a predetermined pick corresponding to the number N of blank hits, only the opening movement and the repulsion movement are operated without weft insertion, and then the normal operation state is entered.

Next, a specific description will be given based on each drawing. As mentioned above, in these figures, the diagonal grid-like figure in the upper part is a copy of the actual opening pattern of the warp thread, and the symbols ○, ×, and △ in the opening indicate normal weft insertion and weft insertion, respectively. The cause of stop or warp stop is shown and weft insertion is prohibited. As an example, the number of blank hits (N) at the time of startup is one.

(1) of FIG. 5 [Starting sequence at the time of warp stop] This sequence shows an example when the cause of stop of the warp stop occurs. The sequence at this time is as follows. The blanking operation at startup will be described later in detail.

During normal operation of the loom → Generation of cause of warpage → Stop command → Prohibition of weft insertion in the cycle next to the cause of stop → 260
Stop near level → leveling command → automatic reverse rotation (leveling operation) → stop (standby) at 300 degrees (starting angle) → manual maintenance by workers → return button operation by workers → automatic 1
Forward rotation (leveling release operation) → Stop at 300 degrees → Automatic reverse rotation → Stop at 300 degrees in defective cycle → Operation button operation by worker → Return of predetermined step (1 step) of solenoid selection opening pattern of dobby device → Starting the blanking in a predetermined step (1 step) (Continuing the opening / beating motion + inactivating the weft insertion / feeding / winding motion) → Passing 0 degree of the defective cycle → Resuming normal operation

In this sequence, the manual maintenance by the worker is performed in the leveling state, but instead of this, it may be performed at the starting angle position of 300 degrees after the leveling state releasing operation.

5 (2) [weft stop (without automatic weft repair)]
Starting Sequence at Time] This sequence shows an example when the weft automatic restoration device 22 is not attached and the cause of the stop of the weft stop occurs. The sequence at this time is as follows.

During normal operation of the loom → Occurrence of weft stop cause → Stop command → Prohibition of weft insertion in the cycle next to stop cause → 260
Stop near-> leveling command-> automatic reverse rotation (leveling operation)-> stop at 300 degrees (starting angle) (standby)-> return button operation by worker-> automatic 1-turn forward rotation (leveling release operation)-> stop at 300 degrees → Automatic reversal → Stop at 180 degrees (outlet opening angle) in weft insertion failure cycle → Manual weft repair by worker → Operation button operation by worker → Automatic reversal → 300 in the cycle one cycle before the stop cause cycle Stop → return of the predetermined step (1 step) of the solenoid selection opening pattern of the dobby device → start of idle driving of the predetermined step (1 step) (continuation of opening / beating motion + weft insertion / feeding / winding motion failure) Operation) → 0 degree of weft failure cycle → Restart normal operation

[3] of FIG. 5 [weft stop (without automatic weft repair)
+ Starting Sequence at the Time of Warp Stop] This sequence shows an example when the causes of stop of the weft stop and the warp stop occur simultaneously in the same cycle. The sequence at this time is as follows.

During normal operation of the loom → Occurrence of weft stop cause / warp stop cause → Stop command → Prohibition of weft insertion in the cycle next to stop cause → Stop near 260 degrees → Leveling command → Automatic reverse rotation (leveling operation) → Stop (standby) at 300 degrees (starting angle) → Manual maintenance by the worker → Return button operation by the worker → Automatic 1 rotation forward rotation (leveling release operation) → 30
Stop at 0 degree → Automatic reverse rotation → 180 in bad weft insertion cycle
Degree stop (opening opening angle) → Manual weft repair by the worker → Operation button operation by the worker → Automatic reverse rotation → Stop at 300 degrees in the cycle one cycle before the stop cause cycle → Dobby device solenoid selection opening pattern Predetermined step (1
Step) return → Pre-determined step (1 step) idle driving start (continuation of opening / beating motion + weft insertion / feeding out)
Winding motion not working) → 0 degree of bad cycle / weft cycle → Normal operation restart

As described above, when the causes of the stop of the weft stop and the warp stop occur at the same time, the sequence is the same as that of FIG. 5 (2) in the case of the weft stop. In this sequence as well, similar to the example of (1) in FIG. 5, the manual maintenance by the worker may be performed after the leveling state releasing operation.

6 (1) [weft stop (successful automatic weft repair)]
Starting sequence in case of]] This sequence shows an example in which the weft automatic repairing device 22 is attached, the cause of the stop of the weft stop occurs, and the automatic repairing operation is successful. The sequence at this time is as follows, and since the leveling operation is not performed, it is outside the scope of the present invention.

During normal operation of the loom → Generation of cause of weft stop → Stop command → Prohibition of weft insertion in the cycle next to the cause of stop → 260
Stop nearly every time → Automatic reverse rotation → 1 of cycle causing stop
Stop at 80 degrees (outlet opening angle) → automatic weft repair operation → automatic reverse rotation → stop at 300 degrees in the cycle one cycle before the stop cause cycle → predetermined step (1 step) of the solenoid selection opening pattern of the dobby device Return → Start of idle driving at a predetermined step (1 step) (continuation of opening / repulsion movement + inoperability of weft insertion / feeding / winding movement) → 0 degree pass of weft failure cycle → Restart normal operation

(2) of FIG. 6 [weft stop (automatic weft repair failure)
Starting Sequence at Time] This sequence shows an example when the cause of stop of the weft stop occurs and the weft repair fails by the weft automatic repairing device 22. The sequence at this time is as follows.

During normal operation of the loom → Occurrence of cause of weft stop → Stop command → Prohibition of weft insertion in the cycle next to the cause of stop → 260
Stop nearly every time → Automatic reverse rotation → 1 of cycle causing stop
Stop at 80 degrees → Automatic weft repair operation → Automatic weft repair failure → Automatic forward rotation → Stop at 300 degrees → Leveling command → Automatic reverse rotation (leveling operation) → Stop at 300 degrees (starting angle) (standby state) → By worker Return button operation → Automatic 1 rotation forward rotation (leveling release operation) → Stop at 300 degrees → Automatic reverse rotation → Stop at 180 degrees (outlet opening angle) in a weft insertion failure cycle →
Manual weft repair by worker → Operation button operation by worker → Stop at 300 degrees in the cycle one cycle before the stop cause cycle → Return the predetermined step (1 step) of the solenoid selection opening pattern of the dobby device → predetermined step (1 step) blanking start (continuation of opening / reeding movement + inactivation of weft insertion / feeding / winding movement) → 0 degree pass of defective weft cycle → restart of normal operation

As a result of failure in weft repair, this sequence is equivalent to the case where the automatic weft repair device 22 is not attached, and after the operation of the return button 9, it is the same as the sequence shown in FIG. 5 (2).

6 (3) [weft stop (successful automatic weft repair)]
+ Start sequence at the time of warp stop] In this sequence, the causes of stop of the weft stop and the warp stop occur simultaneously in the same cycle and the weft repair is performed by the automatic weft repair device 2
2 shows an example of a successful case. The sequence at this time is as follows.

During normal operation of the loom → Occurrence of weft stop cause / warp stop cause → Stop command → Prohibition of weft insertion of the next cycle of stop cause → Stop near 260 degrees → Automatic reverse rotation → 180 degree cycle of stop cause cycle Stop at (outlet opening angle) → automatic weft repair operation → automatic forward rotation → stop at 300 degrees → leveling command → automatic reverse rotation (leveling operation) → stop at 300 degrees (starting angle) (standby) → manual operation by a worker Repair → Return button operation by worker → Automatic 1-turn forward rotation (leveling release operation) → Stop at 300 degrees → Automatic reverse rotation → Stop at 300 degrees in the cycle one cycle before the stop cause cycle → Operating button by worker Operation → Solenoid selection of the dobby device Return of the predetermined step (1 step) of the opening pattern → Start of idle driving of the predetermined step (1 step) (Continuation of opening / beating motion + weft insertion / feeding out) Non-operation of the take-up exercise) → Kay weft 0-degree passing bad cycle → normal operation resumes

This sequence is equivalent to the case where weft stop does not occur as a result of successful weft repair, and after the operation of the return button 9, it is the same as the sequence shown in FIG. 5 (1).

7 (1) [weft stop (automatic weft repair failure)]
+ Start sequence at the time of warp stop] In this sequence, the causes of stop of the weft stop and the warp stop occur simultaneously in the same cycle and the weft repair is performed by the automatic weft repair device 2
2 shows an example of a failure. The sequence at this time is as follows.

During normal operation of the loom → Cause of weft stop / cause of warp stop → Stop command → Prohibition of weft insertion in the cycle next to the cause of stop → Stop near 260 degrees → Automatic reverse rotation → 180 degree of cycle causing stop cause Stop at (outlet opening angle) → automatic weft repair operation → automatic weft repair failure → automatic forward rotation → stop at 300 degrees → leveling command → automatic reverse rotation (leveling operation) → 3
Stop (standby) at 00 degrees (starting angle) → Manual repair by workers → Return button operation by workers → Automatic 1 rotation forward rotation (leveling release operation) → Stop at 300 degrees → Automatic reverse rotation → Weft insertion defective cycle At 180 degrees (outlet opening angle) → Manual weft repair by worker → Operation button operation by worker →
Automatic reverse rotation → Stop at 300 degrees in the cycle one cycle before the stop cause cycle → Return of the predetermined step (1 step) of the solenoid selection opening pattern of the dobby device → Preliminary step start (1 step) Continuation of repulsion movement + deactivation of weft insertion / feeding / winding movement) →
Passing 0 degree of weft failure cycle → restart normal operation

This sequence is equivalent to the case where the automatic weft repair device 22 is not attached as a result of weft repair failure, and after the return button 9 is operated, it is the same as the sequence shown in FIG. 5C.

Next, FIG. 8 shows a specific example of this embodiment for realizing the leveling state. That is, in this example, the leveling state is realized with a small rotation amount of the loom 1 by instructing an opening pattern which is the current solenoid selection opening pattern output from the electronic dobby device 19 and which is reversed. It is a thing. In this figure, the actual opening pattern is 5 → 6 → 1 → 2 → 3 → 4 → ・
Is set as a state of 6 cycles, that is, one repetition every 6 rotations of the loom 1. In the electronic dobby device 19, the solenoid selection opening pattern always precedes the actual opening pattern by one cycle, and the period in which the signal of the solenoid selection opening pattern is output is from the closing operation of a certain cycle to the next cycle. The movement is limited to a predetermined period of movement to the opening operation, that is, only near the warp cross timing.

In FIG. 8, the cause of the stop occurs in the actual shedding pattern 2, the stop signal is output in the latter half of the cycle, the braking operation starts from there, and the loom is near the end of the cycle of the next actual shedding pattern 3. Shows an example of stopping. At this stop position, the solenoid selection opening pattern is 5.

Here, FIG. 9A shows an example of the setting state of the normal shed pattern for weaving, which is composed of six heald frames H1 and H1.
2, ... H6. In the figure, the shaded portion indicates the upper position of the heald frame, and the non-hatched portion indicates the lower position of the heald frame.
In the process of changing from the pattern 1 to the pattern 6, the two heald frames are always set in the lower position and the other ones are set in the upper position.

As described above, the control device 2 sets the leveling state by reversing the loom 1 by one rotation during the leveling operation, but prior to that, the current solenoid selection opening pattern 5 is changed to the current actual opening pattern 3 Change to the inversion pattern 3 of. In the drawing, the inverted pattern 3 is displayed with a bar above the numeral. FIG. 9B shows a reverse pattern with respect to the normal opening pattern. The reversal pattern referred to here means that the vertical relationship of the heald frame of the normal opening pattern is reversed.

Therefore, the control device 2 is the electronic dobby device 1
After reversing the solenoid selection opening pattern of 9, the loom 1 is rotated about one revolution. By the reverse rotation of one rotation at this time, the actual opening pattern 3 changes according to the reverse pattern 3. This allows all heald frames H
1, H2, ... H6 move up and down. That is, in the normal actual opening pattern 3, four heald frames H1 and H
2, H3, H6 are set to the upper side, and the other two heald frames H4 and H5 are set to the lower side, but in the reversing process of one rotation, the upper heald frames H1, H2 are set by the reversing pattern 3. , H3, H6 move downward and the lower heald frames H4, H5 move upward, so that the upper and lower heald frames intersect with each other near the angular position of the loom 1 (for example, 30
(0 degree), all the heald frames H1, H2, ..., H6 can be set at the leveling position, that is, in the middle between the upper and lower sides.
Such a function is not limited to the normal opening pattern which is repeated once every 6 cycles, and is the same as the plain weaving opening pattern as shown in FIG. 9C and other opening patterns. In order to release the leveling state, the loom 1 is rotated by a predetermined amount after returning the solenoid selection opening pattern from the inversion pattern for leveling to the predetermined normal opening pattern for weaving, as in the conventionally known method. Can be realized by

As already described in the section of the prior art, in order to realize the leveling state, the solenoid selection opening pattern of the electronic dobby device 19 is changed from the normal opening pattern for weaving to the plain weaving pattern for leveling. ,
In the known leveling method of moving the loom 1 to the closing angle, at least one cycle, that is, one or more rotation operation of the loom 1 is required to align all the heald frames in line. On the contrary, the same amount of rotation of the loom was required to restore the leveling state to the normal open state. Therefore, in the process of realizing the leveling state, 2
Since more than one beating motion is unavoidable, the beating motion at the time of reverse rotation has different motion characteristics such as acceleration from the normal beating motion in the normal direction. Was becoming. Also, with such forward and reverse rotation,
Since many rotation amount operations are required, the operation rate of the loom 1 is also reduced. On the other hand, in the case of the leveling method of reversing the solenoid selection opening pattern corresponding to the current actual opening pattern as in this embodiment, the minimum leveling motion and the complete leveling state with a small rotation amount are used. As a result, the occurrence of weaving bars can be prevented and the operation rate does not decrease.

Next, FIGS. 10, 11 and 12 show an example of the idle driving method for each of the stop and the stop. In these figures, when passage failure / weft insertion failure occurs as the cause of stop in the actual opening pattern 2, a stop signal is output, the braking operation is started from that point, and weft insertion is blocked in the next actual opening pattern 3. Then, the loom 1 stops near the end of the cycle of the actual shedding pattern 3. It should be noted that these figures are for explaining only the blanking start-up method, and for convenience of explanation, the start-up method of the invention according to this application, that is, the procedure for canceling the setting of the leveling is omitted. .

In the case of the warp stop shown in FIG. 10, when the loom 1 reverses up to nearly 300 degrees of the actual shedding pattern 2 to repair the warp, the electronic dobby device 19 detects the reversal and the solenoid selection shed pattern 5 is detected. Is returned to the solenoid selection opening pattern 2 which is the previous step by 3 steps, and is moved backward. After that, for example, when the loom 1 is started after four idle runs, the solenoid selection opening pattern 1 at the current stop position is
The solenoid selection opening pattern 6 is set by returning only one step.

A normal weaving movement is started from the actual shedding pattern 3 after giving an operation command to the loom 1 and performing four idle runs. During the four blank driving periods, the electronic dobby device 19 changes the solenoid selection opening pattern in the order of 6 → 1 → 2 → 3 in synchronization with the rotation of the main shaft 17, and the solenoid selection opening pattern 3 and the first ones are changed. In the normal cycle of, the regular actual opening pattern 3 is set. As a result, the phase of the opening and the phase of the fabric structure match each other regardless of the blank firing. Therefore, the actual opening pattern 3 is formed subsequently to the actual woven fabric weave structure in which the actual opening pattern 2 has already been formed, and a normal continuous weave structure is formed.

Next, in the case of the stop due to the weft stop in FIG. 11, the weft is reversed from the stop position of the loom 1 only 1.5 times to repair the weft, and the weft is repaired in the open state. By doing so, it stops near 300 degrees of the cycle of the actual opening pattern 1. During this time as well, the solenoid selection opening pattern is reversed in the order of 2 → 1 → 6 as described above.

Here, the solenoid selection opening pattern is set in the opposite direction by one step in correspondence with the four times of idle driving, and is set to the solenoid selection opening pattern 5. At the time of subsequent activation, the regular weaving movement is started from the actual shedding pattern 2 after four idle shots.

The example shown in FIG. 12 is an example in which when the vehicle is stopped after the stop, the number of blank shots is set to 6 and the engine is started. In this case, the solenoid selection opening pattern is the current 1 to 4
It is set in the opposite direction for 3 steps. In the case of 6 times of idle driving, the number of idle driving matches the number of 1 repeating steps of the actual shedding pattern and the solenoid selection shed pattern. Therefore, the actual shedding pattern during the blanking operation is the normal shed pattern during weaving. Can be made continuous with the same opening pattern. By the way, in FIG. 10 and FIG. 11, the actual opening patterns at the initial stage of the idle driving are 3 → 6 and 2 respectively.
→ 5, which results in a result different from the normal shed pattern during weaving, and it is expected that weaving bars will occur due to this, but this has the effect of preventing this.

FIG. 13 shows a starting method by reverse run idle driving in the case of a stop. In this reverse reverse idle driving start method, the loom itself is reversed in the idle driving state four times, and then idle driving is performed four times at the time of starting, and then the regular weaving movement is started from the actual shedding pattern 3. It In this start-up method, the weaving condition is generated because the condition of the cloth fell changes due to blanking during reverse rotation.

The above-mentioned method of starting the blank driving can be applied to the starting method of the invention according to this application. That is,
In the starting method of the invention according to this application, when the operation button 6 is set and operated at the time of starting the loom, the current solenoid selection opening pattern is changed to a value in consideration of the number of times of idle driving in idle driving. After that, if the blanking operation is performed a predetermined number of times, an actual shedding pattern continuous with the state of the fabric can be realized in the process of shifting from the blanking operation to the regular weaving operation.

In the above-described embodiment, when the cause of the stop is other than the weft cause, for example, when the vehicle is stopped or stopped by the stop button 7, the operator operates the operation button 6 after releasing the leveling state by operating the button. However, instead of this, the button operation for canceling the leveling state is omitted, and the operation button is operated directly from the leveling state, and the leveling state is released in the process of the blank driving after that. It is also possible to do so (see FIG. 14).

[0064]

According to the first aspect of the invention, regardless of the cause of the stop, the start operation is always performed after the operation of the return button after the operation of the return button. It is possible to prevent the occurrence of steps.

In addition, in the second invention, in addition to the same effect as in the first invention, the sequence when the operation button is operated is the same regardless of the cause of the stop. There is no fear of confusion, and the stability of operation can be secured.

Further, according to the third aspect of the invention, the leveling cancellation and the starting operation are performed by the unified operation procedure of always operating only the operation button regardless of the cause of the stop. It is possible to prevent the occurrence of a weaving step.
