TECHNICAL FIELD OF THE INVENTION The present invention relates to a method of tying splicing threads to the ends of the cut warp threads during weaving when the warp threads are broken, and passing the splicing threads through a belt or reed.

BACKGROUND ART When the warp threads are cut during weaving, the loom automatically stops upon receiving a warp stop signal from a loomper device or the like.

At this time, the weaver takes out the cut warp threads from a large number of warp threads, ties a splicing thread to the end of the cut warp thread, and repairs it by passing it through a belt or reed, and sets the loom in a state where it can be restarted. . In this way, conventional warp repair work relies entirely on the manual labor of craftsmen.

supported by the belt 112 by a bracket) 119;
A motor 116 allows it to move forward or backward.

Next, FIG. 9 shows the electrical connection relationship between the controller 170 and the functional members. The controller 170 has a built-in program for executing the method of the present invention, and is connected to the dropper device 5, yarn sensors 29, 30, etc. on the input side, as shown in FIG. On the output side, it is connected to controllers 171, 172, .

These controllers 171, 172, . . . 190 are assembled as on/off control elements such as rotation control, on/off or switching control of a pressurized air source, and solenoids, depending on the object to be controlled.

Effect of the Invention The automatic warp repair device 1 is controlled by a controller 170. Therefore, the controller 170 stores in advance a program necessary for a series of operations based on the automatic warp repair method of the present invention. This series of operations is executed in the steps shown in FIG.

When the warp yarns 2 are cut during weaving, the dropper 11 at the position corresponding to the cut warp yarns 2a, 2b falls and comes into contact with the electrode bar 14, as shown in FIGS. 2 and 11(a). 5 generates an electrical stop signal and generates a stop signal to the control system of the loom. For this reason,
The rotation of the loom is automatically stopped at the appropriate stop angle for the next weft cycle.

When the rotation of the loom stops, for example,
The No. 1 automatic warp yarn scrap removal device automatically detects the position of the dropped dropper 11 while moving, and then grasps the dropper 11 and reciprocates it in the weaving width direction to remove the cut warp yarns. 2a, 2b
By displacing the normal warp yarns 2 adjacent to each other to the weaving end side, a space is formed between the cut warp yarns 2a and 2b, and after setting them in a state where they can be easily taken out, the warp yarns 2 are cut from among the many warp yarns 2. Take out the warp threads 2a.

Controller 170 then starts the program of FIG.

First, the controller 170 inputs a warp yarn breakage position signal from the above-mentioned warp yarn breakage automatic take-out device or other known warp yarn breakage position detection device.
2 drives the drive motor 54, and the belt separating device 5
0 to the position of the dropper 11 in the fallen state, where the controllers 185, 186 and the air cylinders 59.
By the operation 60, the separation members 63 and 64 are raised between the two warp yarns 2 adjacent to the left and right sides of the cut warp yarn 2a12b. At this time, since the belt separating device 50 is located on the side of the drawer 11, it is easily inserted between the warp yarns 2 that were displaced when the previously cut warp yarns 2a were taken out. Furthermore, the controller 183,184 and the air cylinder 5
5.56, the separated members 63, 64 in the raised state are moved away from each other. As a result, the dropper 11, belt 7, and reed feathers that are pushing the normal warp yarns 2 through them move in a direction away from the cut warp yarns 2a, 2b, making it easy to take out the ends of the cut warp yarns 2a, 2b. Set to .

At this time, the belt detection device 100 is also moved to the position of the dropper 11 in the fallen state, similarly to the belt separation device 50, by rotating the pair of pulleys 101 using a drive motor (not shown).

When such separation processing is completed, controller 1
After confirming that the warp breakage position signal is input, 70 starts the motor 20 for position control and controls its rotation amount by the controller 171, thereby moving the bracket 3 to the standby position on the weaving end side. from the position to the position of the dropper 11 in the dropped state, and align the suction tube 21 with the end of the cut warp yarn 2a in the above-mentioned taken out state,
By setting the controller 172 to the ON state, an air flow in the suction direction is generated inside the suction tube 21, and a suction operation is started. Due to this airflow, the ends of the cut warp yarns 2a enter the interior of the suction tube 21, as shown in FIG. 12(a), and finally reach the predetermined position of the knock 22. This condition is detected by turning on the thread sensor 29 and is given to the controller 170 as a command for the next step. The suction tube 21 may be made vertically movable by an actuator, and the suction tube 21 may be lowered during suction to directly suction the cut warp yarns 2a that can be easily taken out by the automatic warp yarn piece retrieval device.

Next, controller 170 operates controller 178,
By the operation of the air cylinder 34 in the almost vertical state, the clamper 25 in the raised position is lowered, the splicing thread 23 is pulled out from the splicing thread bobbin 24, and the opening position of the suction tube 21 is moved as shown in FIG. 12(b). After moving it close and confirming completion of the descent, the controller 176 drives the solenoid 32 and sets the clamper 25 to the open state. At this time, the ends of the joining yarns 23 are guided to a predetermined position of the knotter 22 by the air flow of the suction tube 21, similarly to the ends of the cut warp yarns 2a. This condition is confirmed by turning on the thread sensor 30 and is given to the controller 170 as a signal to proceed to the next step.

Therefore, the controller 170 raises the clamper 25 using the controller 178 and the air cylinder 34 and then operates the controller 173 and the knotter 22 to
As shown in FIG. 12(c), the ends of the cut warp yarns 2a and the ends of the joining yarns 23 are set in a connected state.

Thereafter, the controller 170 stops the suction operation of the suction tube 21 after an appropriate period of time has elapsed, and instead causes the suction vibrator 33 to be operated by the controller 177, and also controls the air cylinder 40 and its controller 181.
As shown in FIGS. 12(c) and 12(d), the suction vibrator 33 is moved forward from the retreated position, and the connecting thread 23 is sucked in and held by the air flow in the suction direction from the middle, as shown in FIGS. 12(c) and 12(d). Around this time, the air flow in the suction tube 21 is interrupted, so the cut warp yarns 2a and splicing yarns 23 in the connected state naturally fall due to gravity and fly out from the inside of the suction tube 21. This can be confirmed by turning off both 29 and 30.

After confirming this, the controller 170 moves the suction vibrator 33 backward after a predetermined period of time has elapsed, closes the clamper 25 after a predetermined period of time has elapsed, and moves the suction vibrator 33 between the joint pobin 24 and the suction vibrator 33 The connecting thread 23 is held again, and then the suction operation by the suction vibrator 33 is stopped.

Next, the motor 93 is turned on, and the belt separation device 50 and the belt detection device 100 move forward in the direction of the cut warp yarns 2a, and after a while, the motor 93 is turned off, so that these devices move a predetermined amount of movement. move and stop.

At this time, the separating members 63 and 64 move close to the belt 7 while remaining in the raised state, so that the distance between the belts 7 on both sides of the cut warp yarns 2a and 2b, and the distance between the cut warp yarns 2a and 2b, as shown in FIG. The distance between the reed feathers through which the warp yarns 2 adjacent to 2b are inserted is further increased. Next, the motor 104 is turned on and rotates in the forward direction, so the sensor 108.
109 both move forward in the direction of the belt 7.

During this forward movement, when the sensor 109 is turned on,
Since the sensor 109 detects that the belt frame 44 is approaching the first belt frame 44, the controller 170 causes the motor 1 to
Counting is started to detect the rotation amount of 04.

Thereafter, when the sensor 108 is turned on, it means that the belt 7 has been detected, the controller 170 stops counting, and calculates the frame number of the belt frame 44 from the counted rotation amount.

For example, if the amount of rotation of the motor 104 necessary to move one belt frame 44 is stored in advance, and the number of times the amount of rotation of the motor 104 counted is the number of times the amount of rotation recorded above is calculated. Desired.

As a result, the identification code 45 of the belt 7 through which the cut warp yarns 2a, 2b are inserted is detected. Next, the controller 170 uses the contents of the storage device 46 and the determined identification code 4.
5, by determining whether the warp threads 2 passing between the same reed blades as the cut warp threads 2a and 2b are left or right, the conditions for the subsequent positioning of the threading device are set. Then, the motor 104 is turned on in the reverse direction, the sensors 108 and 109 are moved backward, and if necessary, the drive motor (not shown) is turned on and the belt detection device 2 is turned on.
After shifting only 100 in the weaving width direction,
), input the position of the cut warp yarns 2as2b, move the pair of expanding members 43 provided between the belt 7 and the reed 8 to that position, and further increase the spacing between the reed feathers by using the adjacent warp yarns 2. Preferably enlarged. Although the pair of enlarged members 43 are not shown, the separating members 63 and 64
It is supported by, for example, the bracket 51 by the same support mechanism as .

Next, the controller 170 drives the air cylinder 39 with the scraper 180, converts the linear movement of the cylinder rond into a rotational movement of the air cylinder 34 with the rack 37 and pinion 38, and moves the clamper 25 to the suction vibrator after the movement. 5, and then drive the air cylinder 34 to move the clamper 25 along with the splicing thread 23 to the suction vibro 5.
After confirming the completion of the descent or from the start of the descent, the suction action by the suction vibro 5 is started, and then the cutter driver 42 is operated, and the splicing thread 23 is cut by the cutter 41. The splicing thread is cut between the bobbin 24 and the clamper 25. One of the splicing threads 23 after being cut is sucked and held by the suction vibrator 33. This condition is detected by turning on sensor 66.

In this way, the end of the connecting thread 23 is positioned between the clamper 25 and the suction vibro 5.

At this time, the splicing yarn 23 having a length sufficient to reach the front of the weave is suctioned into the suction vibro 5 from the suction vibro 5.

Next, controller 170 outputs a start signal to control device 120. As shown in FIG. 13, this control device 120 is composed of a feed controller 130, a pulse generation circuit 132, a first counter 134, a gate circuit 136, a second counter 1401, a comparison circuit 142, and a setting circuit 144. ing.

When the feed controller 130 receives the start signal, it first turns on the motor 113 via the controller 189 and moves the threading device 110 in the weaving width direction at a relatively high speed. At this time, the feed controller 130 sends a pulse signal from the pulse generation circuit 132 representing the amount of rotation of the motor 113 to the first counter 1.
The information is input sequentially through 34. Then, when the count value of the first counter 134 reaches a preset value corresponding to a position slightly before the warp thread breakage position,
The feed controller 130 outputs an "H" level signal to the gate circuit 136 and sets the motor 113 to a low speed. After that, when the sensor 118 passes the first reed, the gate circuit 1
36 is opened and then closed again at the rising edge of the detection signal output when approaching an adjacent reed blade, during which the reference pulse from the pulse generating circuit 132 is sent to the input terminal of the second counter 140.

Therefore, the second counter 140 measures the interval between the reed blades by counting the number of the reference pulses, and outputs the measured value to the comparison circuit 142. then the second
The counter 140 sequentially measures the distance between adjacent reed blades each time the sensor 118 passes through the reed blade, and outputs the value to the comparison circuit 142.
Each time a measured value is input, it compares the measured value with the reference value set by the setting device 144, and when the measured value exceeds the reference value, it sends an “H” level signal and outputs it to the controller 130. . The feed controller 130 inputs and stores the count value of the first counter 134 at that time, that is, the rotation amount of the motor, every time the signal from the comparison circuit 142 is input, and receives the signal from the comparison circuit 142 twice. At the time of input, the driving of the motor 113 is stopped. Then, feed controller 1
30 inputs the previously performed conditions from the controller 170, determines the liquid state between the two liquid states through which the cut warp yarns 2a and 2b are inserted, and determines the corresponding rotation amount stored above. Reverse the motor so that In this way, by detecting locations with large gaps and further determining the location through which the cut warp threads 2a and 2b are inserted based on the previous conditions, the liquid position of the cut warp threads can be determined accurately and quickly. can be determined.

When the positioning of the threading device 110 is completed, the controller 170 then operates the cutter 67 via the controller 187 to cut and remove the cut warp yarns 2b between the reed 8 and the belt 7. Note that when the positioning of the threading device 11O is completed, the amount of rotation of the motor 113 is used as the amount of rotation for positioning other devices.

After this, the controller 170 turns on the motor 116 in the normal rotation direction, advances the hooked needle 117, and inserts it into the through hole of the belt 7 from the liquid state. Then, by rotating the motor 116 in the reverse direction, the needle 117 is retracted. During the forward movement, the hooked needle 117 enters the through hole of the belt 7 through the expanded liquid state, hooks the splicing thread 23 stretched in the direction intersecting the hook, and connects the clamper 25 and the suction vibro 5. By retreating while locking the splicing thread 23 positioned in the figure 7 shape, the splicing thread 23 is guided between the through hole of the belt 7 and the liquid state, and the retraction is completed.

After that, the suction vibro 5 stops the suction operation, the clamper 25 releases the joining thread 23, and then the air cylinder 39
is activated, and the air cylinder 34 is also returned to its original position. Furthermore, the clamper 25 is returned to its original position by the operation of the air cylinder 34.
Next, the knock 22, the belt separating device 50, and the expanding member 43
, the belt detection device 100 and the threading device 110 both perform the return operation, completing the series of operations.

When passing the hooked needle 117, it is preferable to align the position of the belt 7 in a straight line between the liquid states.As a technique for this purpose, there are techniques such as those disclosed in Japanese Patent Application Laid-open No. 50-20067 and Japanese Utility Model Publication No. 29-17172. Just apply the device.

That is, by supporting the above-mentioned device with the same structure as the belt separating device 5o, it is possible to move in the weaving width direction. If the device is operated after positioning the device by rotating the drive motor based on the amount of rotation of the motor 113 input from the control device 120, the belt 7 can be positioned and fixed with high precision. can.

This threading device 110 may be located in front of the liquid state,
Alternatively, it may be provided at the rear of the belt 7. The piecing thread 23 thus passed through the liquid state by the threading device 110 and guided near the fabric front is processed by the device proposed by the applicant (the device of Japanese Patent Application No. 1988-298805). For example, complete automation is possible, even down to the automatic restart of the loom.

In this embodiment, the °2
It is assumed that the warp threads 2 of the book are regular with respect to each other, in particular with respect to the numbering of the belt frame 44.

For this reason, an identification code 45 corresponding to the number of the belt frame 44 is given to the belt 7, which is the member through which the warp threads 2 are inserted, and all the droppers 11 are The identification code 45 of the dropper 11 may be stored for each warp thread 2 inserted between the same liquids, and the identification code of the dropper 11 through which the cut warp thread is inserted may be detected when the thread breaks. . According to this method, even if the warp yarns 2 inserted between the same liquid state do not have the above-mentioned regularity, the warp yarns 2 inserted in the liquid state through which the cut warp yarns 2a and 2b are inserted can be identified. be able to.

Further, in the above embodiment, both of the warp yarns 2 adjacent to the cut warp yarns 2a and 2b are moved, but in addition to this, the cut warp yarns 2a and 2b are inserted from the identification code 45 into the same liquid space as the cut warp yarns 2a and 2b. The condition may be that the warp threads 2 are determined and moved only, and positioned at a location with a large liquid spacing.

Furthermore, in the above embodiment, by directly measuring the distance between the liquids, a location with a large gap between the liquids is detected; however, the present invention is not limited to this. The two are moved in the weaving width direction while detecting the amount of light passing between the liquids, and by comparing whether or not the light amount exceeds a predetermined value, it is possible to detect a location where the gap between the liquids is large. You can.

Although the belt separating device 50 is movable between the dropper device 5 and the belt 7, the present invention is not limited to this, and a plurality of belt separating devices 50 fixed in two directions of the warp may be provided. Furthermore, since the reeds may easily spread depending on the yarn type, fabric structure, etc., it is also possible to provide only one belt separating device 50 fixedly at any position, preferably on the romper device 5 side.

Furthermore, although the above embodiments are based on the assumption that two warp yarns 2 are inserted between the liquids, the present invention can be applied even when three or more or only one warp yarn is inserted.

When one warp thread 2 is passed through the reed, the pair of separation members 63 and 64 spread out at least one of the two normal warp threads 2 on both sides of the cut warp threads 2a and 2b, and separate the cut warp threads. This increases the distance between at least one of the reed blades 2a and 2b adjacent to each other. Thereafter, the spread reeds are detected by the sensor 118, and if one of them is moved, the positional relationship of the moved adjacent warp yarns 2 with respect to the cut warp yarns 2a, 2b is the condition, and if both are moved, the reed feathers are detected by the sensor 118. , can be used to identify the reeds of the cut warp yarns 2a, 2b, subject to the moving direction of the sensor 118. Therefore, it is possible to position and move the threading device with the same accuracy as in the above embodiment. Further, the operation of widening the interval between the reed blades can also be realized by providing a tapered member in the threading device 110 so as to be able to move forward and backward, and inserting this into the liquid space.

Effects of the Invention In the present invention, by moving the warp yarns adjacent to the cut warp yarns, the distance between the reed blades through which the cut warp yarns should be passed again or the adjacent reed blades is increased, and this is detected. Since the threading device is positioned, the positioning can be performed with high precision and quickly. Furthermore, when a plurality of warp yarns are inserted between one liquid, the interval between the reed feathers to be threaded can be directly expanded, so that the warp threads can be threaded easily after repair. In addition, when a warp thread breaks, it is easy to identify the warp thread that has been inserted between the same liquids as the cut warp thread by simply detecting the identification code of the member through which the cut thread was inserted, rather than actually detecting the warp thread. becomes.
