Description

The present invention relates to an apparatus for adjusting a loom (pre-weaving) position before restarting a loom after yarn repair, in other words, when the loom stops.

When the weaving machine is stopped, if the weft is pulled out of the weaving port by the weft repairing operation, the weaving port position is changed by the amount of the weft being pulled out. Therefore, it is necessary to adjust the weaving port position before restarting the loom. For this reason, usually, the operator manually rotates the winding motor and the delivery motor to restore the loom position to the position immediately after the loom stops. When this weaving position is not accurately restored, a stop stage occurs in the woven fabric.

For example, the technique of Patent Document 1 discloses that each time a switch is pressed, the take-up motor and the feed motor are rotated by the amount of movement of one pick unit to move the weaving position. According to the technology, even if we try to adjust the weaving position after removing one weft, the weft actually does not move by the amount of movement of one pick unit due to factors such as warp tension, but actually the weft Since it is not inserted, even if the weaving position is moved by one pick unit, the weaving position cannot be accurately restored. In addition, when a plurality of wefts are pulled out, the error in the length between the picks further increases, making it more difficult to restore the weaving position.

Further, the technique of Patent Document 2 discloses that the winding motor and the feeding motor are rotated while the switch is kept pressed, and the weaving position is adjusted by visual measurement. According to the technique, since the operator cannot grasp the rotation amount of the motor during adjustment, it is very difficult to accurately adjust the weaving position.

From the above situation, there is a drawback that it is difficult to prevent the occurrence of a stop stage because any of the above-described means for adjusting the weaving position cannot be accurately restored.
Japanese Patent Publication No. 3-67132 Japanese Utility Model Publication 1-39727

Accordingly, an object of the present invention is to prevent the occurrence of a stop stage when the loom is restarted by making it possible to accurately adjust the position of the weave after the weft repair.

Based on the above-mentioned problems, the present invention provides a dedicated winding motor and a warp beam for rotating the surface roll, which are provided separately from the main motor for driving the main shaft based on the rotation command when the loom stops. At least one of the dedicated delivery motors to be driven to rotate, and when having one, the dedicated motor, and when having both, at least one of the dedicated motors, while the loom is stopped In the weaving position adjusting device driven independently from the main shaft of the loom based on the rotation command, the weaving position adjusting device includes a manual operation device that generates the rotation command based on a manual operation, and a manual operation device A drive control device that drives the dedicated motor by a rotation amount corresponding to an amount including a value after the decimal point of one pick independently from the main shaft by outputting one rotation command; Characterized Mukoto (claim 1).

The drive control device calculates the amount of rotation of the delivery motor based on the change in the diameter of the warp wound around the warp beam and the weft density (Claim 2), or the amount of rotation of the take-up motor is surface roll. Is calculated based on the diameter and the weft density (claim 3).

The amount of rotation of the motor by one rotation command can be set individually in either the number of wefts removed at the time of weft repair or the number of times of weaving of the loom (Claim 4), or It can be set according to the opening pattern of the warp.

The drive control device automatically sets the amount of rotation corresponding to the number of times the loom is delivered while the loom is stopped, and automatically drives the motor by the set amount of rotation. An indicator is attached to the drive control device, and the indicator displays a history of the amount corresponding to the amount of rotation of the motor in units of picks or mm for each rotation command from the manual operation device. ). Note that “stopped” specifically refers to the case where the weaving operation is stopped.

According to the first aspect, the number of rotations in which the operator presets the rotation amount in units of less than one pick, specifically in units of picks or mm, according to the weft density, warp tension value, etc., and withdraws the weft at the time of weft repair. If the above operation is performed with a switch or the like according to the number of times the loom is fed, the position of the weaving mouth is moved by the amount corresponding to the amount including the value after the decimal point of one pick by the motor. It is possible to accurately restore the loom position immediately before stopping the loom while grasping the rotation amount. As a result, the stop stage can be prevented. Further, since the position of the weaving opening can be finely adjusted by the amount of rotation corresponding to the amount including the value after the decimal point of the pick, even when the number of operations of adjusting the weaving edge is wrong, the stop stage can be minimized. The number of times of squeezing is the number of times that the weft is exposed in the opening by reversing the main shaft once.

According to claim 2 and claim 3, the amount of rotation is calculated based on the change in the winding diameter of the warp and the weft density that change during weaving, and on the basis of the diameter and the weft density of the surface roll. The weaving position can be adjusted accurately.

According to the fourth aspect of the present invention, the amount of rotation of the motor can be individually set in detail individually in either the number of wefts removed at the time of repairing the wefts or the number of times of weaving of the loom. Actually, as the number of wefts removed at the time of weft repair increases, the error of the weaving position gradually increases. Specifically, the length between the wefts in each weft insertion becomes longer than the length corresponding to one pick. For example, the first pick, 1.1 picks, second pick 1.2 picks, third pick 1.3 picks, etc., so as the number of wefts removed or the number of times the loom is fed out, the level is increased with respect to the first rotation amount. Therefore, the weaving position can be restored more accurately.

According to the fifth aspect, since the degree of the influence of the warp tension by the opening pattern is large, the position of the weave can be adjusted more accurately by setting according to the opening pattern.

According to the sixth aspect, since the operator automatically adjusts the weaving position without manual operation, the operator's weaving position adjustment work can be simplified and the burden on the operator can be reduced.

According to claim 7, since the amount corresponding to the rotation amount in units of pick or mm for each rotation command from the manual operation device, in other words, for each operation is displayed as a history, The number of adjustments of the weaving position and the amount corresponding to the rotation amount of each motor for adjusting the weaving position can be easily grasped.

FIG. 1 shows a main part of a loom 1, a loom control device 2, and a loom position adjusting device 10 according to the present invention. In FIG. 1, the warp 3 is sent out as a sheet from the warp beam 4, passes through the tension roll 5, forms an opening 8 by the vertical movement of the reed 6, intersects the weft 7 at that position, and is woven by the reed 9. It is beaten in the mouth 11 and becomes a woven fabric 12. The woven fabric 12 is wound around the outer periphery of the cross beam 13 while being wound around the two rolls 21 and the surface roll 22.

The warp beam 4 is controlled by a delivery control device 14 and a delivery motor 15. In other words, the feed control device 14 detects the tension of the sheet-like warp 3 at the position of the tension roll 5 by the tension detector 20, and the winding diameter of the warp 3 by the warp beam 4 (warp beam 4) by the winding diameter detector 16. ), And the delivery motor 15 is driven by the drive amplifier circuit 17 in accordance with the detected tension information (tension signal) and the winding diameter information (winding diameter signal), and the rotation of the delivery motor 15 is controlled by the encoder 18. The amount of rotation of the delivery motor 15 (the delivery amount of the warp 3) is controlled while confirming under feedback control. The rotation of the delivery motor 15 is transmitted to the warp beam 4 by a reduction gear 19 having a large reduction ratio. Note that the winding diameter can be calculated by acquiring the rotation amount of the feeding motor 15 by the feeding control device 14 without using the winding diameter detector 16, for example.

The surface roll 22 is driven by a winding motor 23 and a speed reducer 24, and rotation control of the winding motor 23 is performed by a winding control device 25. The winding control device 25 drives the winding motor 23 by the drive amplification circuit 27 in synchronization with the rotation of the main shaft 26 of the loom 1, and confirms the rotation of the winding motor 23 by the encoder 28 under feedback control. However, the rotation amount of the winding motor 23 (the winding amount of the woven fabric 12) is controlled. Although not shown, the cross beam 13 is driven by a known device. Thus, the delivery motor 15 and the winding motor 23 are provided and driven independently of the main motor (31) that drives the main shaft (26).

Further, the rod 6 is driven by an opening drive mechanism 29, and the opening drive mechanism 29 is controlled by an opening control device 30 that synchronizes with the rotation of the main shaft 26. The main shaft 26 is driven by a main motor 31, and its rotation is detected by an encoder 38, and the detected rotation signal is sent to the winding control device 25 and the opening control device 30.

The loom control device 2 includes a storage device 32 and a drive control device 33 in addition to the above-described delivery control device 14, take-up control device 25, and opening control device 30. The storage device 32 stores the rotation amount data input by the setting device 34. In order to move the position of the weave 11, the drive control device 33 gives a calculation unit 36 for calculating the sending amount of the warp 3 and the winding amount of the woven fabric 12 and gives a rotation command for the sending amount to the sending motor 15. In addition, a command device 37 is provided for giving a winding amount rotation command to the winding motor 23. The weaving condition data, the delivery amount data, the winding amount data, and the like can be displayed on the display unit 35 as necessary.

The loom adjustment control device 10 includes a part of the storage device 32 and the drive control device 33 of the loom control device 2, and includes a manual operation device 40 in addition to the setting device 34 and the display device 35 described above. In order to generate a rotation command based on a manual operation when the loom 1 is stopped, the manual operation device 40 has five switches, that is, an operation switch 41, a loom adjustment forward rotation switch 42, a loom adjustment reverse rotation switch 43, a loom normal rotation switch. 44. A loom reverse switch 45 is provided.

The operation switch 41 is pressed (ON) when the operation of the loom 1 is started. The loom forward rotation switch 44 is used for weaving to wind the sheet of warp 3 around the surface roll 22 and the cross beam 13 when the machine is in progress. In weaving, weft insertion is performed manually for several picks. The loom reverse switch 45 is used to reverse the main shaft 26 of the loom 1 by a certain amount each time it is pressed once when the weft 7 is repaired. In this embodiment, each time the loom reversing switch 45 is pressed once, the main shaft 26 reverses by one rotation, and the number of times the loom reversing switch 45 is pressed is defined as the number of times of extraction.

Each time the weaving head adjustment forward rotation switch 42 is pressed once, at least one of the feeding motor 15 and the winding motor 23 is rotated by a predetermined rotation amount, which will be described later, and the position of the weaving mouth 11 is changed to the winding side direction. This is used when moving a predetermined amount. Each time the weaving head adjustment reversing switch 43 is pressed once, at least one of the sending motor 15 and the winding motor 23 is reversely rotated by a predetermined rotation amount, which will be described later, and the position of the weaving mouth 11 is set in the direction of the sending side. Used when moving by a predetermined amount. It should be noted that the weaving edge adjustment forward rotation switch 42 and the weaving edge adjustment reverse rotation switch 43 can also be configured as one common weaving edge adjustment switch that moves the position of the weaving hole 11 in one direction.

Data for moving the position of the weave 11 is individually set by the setting unit 34 as a sending amount indicating the rotation amount of the sending motor 15 and as a winding amount indicating the rotation amount of the winding motor 23. When the position of the weaving port 11 is moved, only the feed motor 15 or the take-up motor 23 may be rotated, or the send motor 15 and the take-up motor 23 may be rotated simultaneously.

The setting device 34 includes a numerical value input device such as a numeric keypad, and includes a calculator or a program for inputting a numerical signal from the numeric keypad and outputting the numerical content to the storage device 32. When the operator inputs the weaving conditions such as the weft density and the opening pattern in addition to the feeding amount and the winding amount by operating the numerical input device of the setting device 34, the operator or program in the setting device 34 Obtains the parameters of the sending amount, the winding amount, and other weaving conditions, and stores the obtained parameters in the storage 32. The delivery amount and winding amount are in units of picks or mm.

When the operator presses the operation switch 41 to input an operation command to the loom control device 2, the loom control device 2 activates the main motor 31, and the feed control device 14, winding according to the set weaving conditions. The take control device 25 and the opening control device 30 are operated to perform weaving. As described above, the feed control device 14 performs feedback control on the feed motor 15, and the winding control device 25 performs feedback control on the winding motor 23. The opening control device 30 outputs an opening command to the opening driving mechanism 29 according to the set opening pattern, and drives the eaves 6. During weaving, all the switches of the manual operation device 40 are interlocked and do not react even if pressed by mistake.

The first embodiment is an example in which the rotation amount less than one pick, in other words, the rotation amount smaller than the rotation amount of the dedicated motors (15, 23) corresponding to the distance between the adjacent wefts 7 is set to be changeable. Here, both the sending amount and the winding amount are set to 0.7 picks. In this case, the amount of movement for moving the position of the weave 11, that is, the amount of rotation of the feed motor 15 and the take-up motor 23 are both the amount of rotation equivalent to 0.7 picks. If either the sending amount or the winding amount is set to 0, the corresponding sending motor 15 or winding motor 23 does not rotate.

FIG. 2 shows a flowchart of the loom adjusting operation when the loom 1 is stopped. This flowchart of the weaving adjustment operation can cope with a cause of stoppage such as a weft insertion trouble or a warp trouble. When a weft insertion trouble occurs, the loom 1 stops, and when a defective weft 7 is pulled out for repair, the weaving port 11 moves forward from the normal position. The adjustment reverse switch 43 is pushed. On the other hand, when the weft 11 is retracted from the normal position by manual weft insertion or the like when repairing a warp trouble such as warp breakage, the operator rotates the weft adjustment forward as a weft adjustment switch. The switch 42 is pushed.

The following description assumes a weft insertion trouble as an example, and assumes that the weaving port 11 moves forward. Therefore, the weaving port adjustment switch in FIG. Of course, when the loom 11 is retracted due to a warp trouble or the like, the weaving mouth adjustment switch corresponds to the weaving mouth adjustment forward rotation switch 42.

The loom adjusting operation in FIG. 2 is in a state where it can be started during the weaving operation of the loom 1. If the loom 1 stops during weaving due to a weft insertion trouble or the like, the process proceeds to step 1.

In step 1, the stop state is displayed on the display 34 as “stop” as shown in the upper right of FIG. Here, when the operator removes a plurality of wefts 7, for example, three from the weaving mouth 11 to repair the weft 7, the operator remembers the number of wefts 7 to be removed, that is, three, and the current position of the weaving mouth 11. In response to the forward movement, first, the weaving adjustment reverse switch 43 is pressed once.

In step 2, was the weaving adjustment switch input? When the answer is Y (yes), that is, when the weaving adjustment reverse switch 43 is pressed (turned on), the process proceeds to step 3. In step 2, when N (no), the process proceeds to step 6, where are the delivery motor 15 and the take-up motor 23 rotating? When the answer is N, the process returns to step 2; when the answer is Y, the process jumps to step 7.

In step 3, the calculator 36 calculates the rotation amount of the feed motor 15 corresponding to the feed amount based on the detected value of the current winding diameter of the sheet-like warp 3 and the set value of the weft density, and calculates the surface. Based on the diameter of the roll 22 and the set value of the weft density, the rotation amount of the winding motor 23 corresponding to the winding amount is obtained by calculation. In addition, although the winding diameter of the warp yarn 3 with the warp beam 4 decreases as the weaving progresses, the diameter of the surface roll 22 does not change.

In the next step 4, the command device 37 gives a rotation command to the delivery control device 14 based on the calculated rotation amount for sending, and gives a rotation command to the winding control device 25 based on the calculated rotation amount for winding. The feed motor 15 and the take-up motor 23 are rotated by a specified rotation amount.

When the feed motor 15 and the take-up motor 23 are rotating as in step 5, the display 35 displays “in operation” on the upper right as shown in FIG.

In the subsequent step 7, when the rotation of the feed motor 15 and the take-up motor 23 is completed, the result is Y, and in step 8, the display 35 displays “stop” in the upper right as shown in FIG. Assuming that each rotation amount of the sending motor 15 and the winding motor 23 corresponds to the “first sending 0.7 winding 0.7” pick, a history of the amount corresponding to the rotating amount is displayed together with the total value in pick units. . This completes the step by one operation of the weaving adjustment reverse switch 43.

In the same manner as described above, the operator repeats the above steps by pressing down the weaving adjustment reverse switch 43 by the number of wefts 7 to be removed. Each time the weaving adjustment reverse switch 43 is pressed, as shown in FIG. 5, the amount corresponding to the rotation amount of the feed motor 15 and the rotation amount of the winding motor 23 when the weaving adjustment reverse switch 43 is pressed. A history of the corresponding amounts is displayed, and the total of the amounts corresponding to the rotation amounts after the loom 1 is stopped is also displayed. Further, only the sum of the amounts corresponding to the rotation amounts of the sending motor 15 and the winding motor 23 may be displayed.

The weaving adjustment switch (weaving adjustment switch (weaving adjustment forward rotation switch 42, weaving adjustment reverse rotation switch 43) is pressed again while the sending motor 15 and the winding motor 23 are rotating. When the mouth adjusting forward rotation switch 42 / weave opening adjusting reverse switch 43) is pressed, a rotation command is continuously sent from the commanding device 37 to the sending control device 14 and the winding control device 25, and the motor (sending motor 15 / winding control) is sent. A command signal is sent to the motor 23). For this reason, the motors (the delivery motor 15 and the take-up motor 23) continue to rotate with the rotation amount increased by the number of times the weaving adjustment switch is pressed.

In addition, the rotation amount corresponding to the amount including the value after the decimal point of one pick to be set is, for example, 0.8 picks in units of 0.1 picks, 1.1 picks, or 0.65 in units of 0.01 picks. You may set it as a pick. Further, when the rotation amount is less than one pick, it can be set as a fixed value by the manufacturer. When set as a fixed value, setting at 1 / integer of 1 pick, such as 0.25 pick and 0.5 pick, is preferable so that cutting is good. In the case of a fixed value, the rotation amount is stored in the storage device 32, and the setting device 34 is unnecessary. The set value is preferably set to a value around one pick that spans one pick such as 0.8 pick and 1.1 pick.

When the weft 7 is repaired, in order to make it easier to remove the weft 7, the main shaft 26 of the loom 1 is reversely rotated by the loom reverse switch 45 and the reed 9 is retracted. In this case, the operator removes the weft 7 Depending on the number of loom reversing switches 45 pressed during weft repair instead of the number of wefts, the weaving adjustment reversing switch 43 as a weft opening adjusting switch may be pressed. For example, if the loom reverse switch 45 is pressed three times to pull out three wefts, that is, if the lead-out is performed three times, the weft adjustment reverse switch 43 may be pressed three times after the weft repair. Depending on the loom 1, the loom reverse switch 45 may be pressed several times for one weft 7 in order to reverse the main shaft 26 by one rotation. In this case, the operator rotates the loom reverse switch 45 by the loom reverse switch 45. The main shaft rotation number is remembered, and the weaving adjustment reverse switch 43 is depressed by the number of times that the main shaft rotation frequency reaches one rotation.

It is also within the scope of the present application to set the sending amount and winding amount by the setting device 34 in units of mm. For example, if the length corresponding to one pick is 2 mm, and set as 0.5 mm, 1 mm, 3 mm, etc., these values are converted to the number of picks, 0.25, 0.5 pick, 1.5 pick, respectively. This is because these values correspond to quantities including values after the decimal point of one pick.

Also, the weaving adjustment switch (weaving adjustment forward rotation switch 42 and weaving adjustment reverse rotation switch 43) may be interlocked while the motors (15, 23) are rotating. For example, when the motors (15, 23) are rotating, the display 35 displays “in operation” on the upper right as shown in FIG. 3. From this time, the weaving adjustment switch (42, 43) is interlocked. After the motors (15, 23) have finished rotating and “Stop” is displayed on the display 35 in the upper right as shown in FIG. 4, the interlock of the weaving adjustment switches (42, 43) is released. Then, the weaving adjustment may be accepted.

The second embodiment is an example in which the second and subsequent rotation amounts are automatically set to the rotation amount corresponding to the actual length between the wefts based on the first rotation amount. The amount of rotation is individually determined, for example, the amount of rotation when the first yarn is extracted and the rotation when the second yarn is extracted, either in the number of extracted wefts 7 at the time of repairing the weft yarn or the number of extractions of the loom 1 The amount of rotation may be set separately, or the amount of rotation at the first mouth-out and the amount of rotation at the second mouth-out may be set separately. In detail, you may set so that it may become large in steps. For example, assuming that the first rotation amount is equivalent to 0.7 pick, the second rotation amount is 0.7 pick × 1.1, and the third rotation amount is 0.7 pick × 1.2. In this way, when the first rotation amount is set, the second and subsequent rotation amounts are automatically set so as to increase stepwise. Alternatively, the first rotation amount may be 0.7 picks, the second rotation amount may be 0.8 picks, and the third rotation amount may be 0.9 picks.

FIG. 6 shows a history display of the amount corresponding to the rotation amount with the increase of the predetermined pick (0.1 pick) in the sending amount and the winding amount. The operator may manually input an amount corresponding to the rotation amount as described above.

Rotation amount of each number of either the number of wefts removed multiple times or the number of times of weaving of the loom 1 is set in advance, and the amount of rotation is rotated at a time by one operation of the weaving adjustment reverse switch 43 You may let them. For example, by setting an amount corresponding to each rotation amount for three wefts to be removed, the operator pulls out the three wefts 7 and then presses the weaving adjustment reverse switch 43 once to remove the wefts. You may adjust the weave 11 for three pieces.

The third embodiment is an example in which the rotation amount is automatically or manually set according to the opening pattern. For example, in the opening pattern, if the top dead center and the bottom dead center continue alternately on the heel 6 for each pick, the tension of the warp 3 tends to increase. Therefore, in the opening pattern, for example, the top dead center and the bottom dead center alternate. The rotation amount is increased by multiplying the set rotation amount by a predetermined ratio in accordance with the number of times following. In addition, the opening pattern here means the opening pattern at the time of weaving adjustment.

The fourth embodiment is an example in which the drive control device 33 automatically calculates an appropriate amount of rotation and rotates each motor (15/23). The drive control device 33 stores the number of times the loom reverse switch 45 is pressed while the loom 1 is stopped (when wefts are repaired), and corresponds to one press of the set loom adjustment switch. Based on the amount of rotation, the amount of rotation for rotating each motor (15, 23) is calculated to automatically set the amount of rotation, and each motor (15, 23) is automatically rotated before the loom 1 is restarted. The memory 32 may store the number of times the loom reverse switch 45 is pressed, and the drive control device 33 may call the number of times the loom reverse switch 45 is pressed from the memory 32.

In the case of a loom in which the loom reverse switch 45 is pressed a plurality of times for one weft 7 in order to reverse the main shaft 26 by one rotation, the number of main shaft rotations reversed by the loom reverse switch 45 is stored in the memory 32. In addition, the number of rotations is automatically set according to the number of times that the number of rotations of the spindle reaches one rotation. As described above, the number of spindle rotations may be converted from the number of times the machine reverse rotation switch 45 is pressed.

The present invention can be applied to both the delivery motor 15 and the take-up motor 23, and can also be applied to only one of the send motor 15 and the take-up motor 23. As is apparent, the weaving adjustment switch is a general term for the weaving adjustment reverse switch 43 and the weaving adjustment forward switch 42. When the loom 11 moves forward while the loom 1 is stopped, the loom 11 is returned to the normal position by operating the weaving adjustment reverse switch 43 before restarting. When the weaving port 11 moves backward, the weaving port 11 is returned to the normal position by the operation of the weaving port adjusting forward rotation switch 42 before restarting.

The present invention is also applicable to a loom that drives the surface roll 22 by the main motor 31 that drives the main shaft 26 without using the dedicated winding motor 23. In this case, weaving position adjustment is performed by driving the delivery motor 15.
