Description

  The present invention relates to a pneumatic tuck-in in a woven cloth movable pile loom and a striking position changing pile loom.

  In the pile loom, the relative distance between the woven fabric's pre-weaving position and the striking position is different between the loose pick and the first pick. On the other hand, in loose picking, the relative distance is large although it varies depending on the desired pile length.

  The pile loom includes a so-called woven cloth moving type pile loom. In order to make the relative distance different between the loose pick and the first pick, the woven cloth is changed every time the loose pick is changed to the first pick or from the first pick to the loose pick. In the publication of Patent Document 1, a servo motor is provided as a dedicated actuator for driving a woven cloth moving device that is a terry motion member in order to move the woven cloth. The servo motor is controlled by a control device different from the control device of the loom motor, and changes the number of wefts of loose pick and first pick constituting one unit pile formation cycle during loom operation, that is, It is possible to change the terry mode, making it possible to obtain pile fabrics with different textures and different designs. Further, the pile loom includes a so-called beating position change type pile loom in addition to the woven cloth moving type pile loom. By making the beating position different between the loose pick and the first pick, The relative distance is increased.

Further, a tuck-in ear may be formed as an ear tissue in the pile fabric. In the gazette of Patent Document 2, in order to obtain a good-looking tuck-in ear, tuck-in is performed in a plurality of times in one unit pile formation cycle, and at least one of them is tuck-in a plurality of weft ends together. In each tuck-in, air is jetted from a nozzle disposed near the end of the woven fabric toward the warp opening, and the weft ends are folded back into the woven fabric.

  However, in the weaving type pile loom, when tuck-in is performed in a plurality of times and the terry mode is changed during operation, the upper warp with the warp opening expanding toward the delivery side as the woven fabric moves. The lower warp crossing position, that is, the pre-weaving position formed by striking the first pick and the warp intersecting position formed by striking the loose pick move relative to the nozzle that ejects the tuck-in air. The space into which the folded weft ends are inserted moves. For this reason, depending on the terry mode, it becomes difficult to insert the weft end into the warp opening, and a tack-in error occurs, which impairs the pile fabric quality. Also, in the beating position change type pile loom, tuck-in is performed in multiple times, and when changing the terry mode during operation, the loose pick is beaten with the change of the beating position. The warp crossing position moves to the weaving machine delivery side with respect to the pre-weaving position formed by striking the first pick and moves with respect to the nozzle, and the space where the folded weft ends are inserted is delivered. Move to the side. Therefore, after the loose pick is described in detail, it is difficult to insert the weft end into the warp opening after the loose pick is beaten, and a tack-in error is likely to occur, and the pile fabric quality is impaired.

  In view of the above-mentioned problems of the prior art, an object of the present invention is to obtain a pile fabric of a tuck-in ear that can be tucked in even if the terry mode is changed during operation in a pile loom and that has a good appearance. is there.

  The present invention is a terry motion member that changes a relative position between a pre-weaving position and a striking position for pile formation, and forms a unit pile formation cycle with a terry motion member driven by a dedicated actuator. A setter in which a plurality of terry modes in which at least one of the number of loose picks and the number of first picks are different are set as control data, and terry motion control for controlling the actuator based on a terry mode changed while the loom is operating A pile loom including a device and an air-type tuck-in device that forms an ear tissue by folding the tip of the weft yarn by air injection, the operation of which is controlled by the tack-in control device is assumed.

  In order to achieve the above object, the pneumatic tack-in apparatus according to the present invention is a pile loom which is premised on the above-described setting, and the setting device further includes the number of picks in one unit pile formation cycle and tack-in during the cycle. A tuck-in mode that includes a specific pick to be performed as information, and a plurality of tuck-in modes in which at least one of the number of picks and the specific pick is different from each other are associated with a corresponding terry mode among the plurality of terry modes. Set as control data, information on the number of repetitions of each terry mode and the execution order of each terry mode are set as control data, and the tuck-in control device is an air type based on a tuck-in mode that is changed during loom operation. It is characterized by controlling the tuck-in device.

  In the pneumatic tuck-in device in the pile loom according to the present invention, when the control data is executed at the same terry mode at different times, a plurality of the same terry mode are executed at different times. One tuck-in mode may always be set for the terry mode. In addition, when the same terry mode is executed at different times, the control data is the same terry mode, and different tuck-in modes may be set for specific terry modes executed at different times. Good.

  According to the pneumatic tuck-in device in the pile loom according to the present invention, the tuck-in time in the cycle, that is, the loose pick and the first pick pick in the cycle, the air is jetted from the nozzle and the weft end is folded back to the woven fabric. However, since the pick for executing the tuck-in is set for each terry mode as the tuck-in mode, the tuck-in mode suitable for the terry mode can be changed in accordance with the change of the terry mode during the operation of the loom. As a result, even if the terry mode is changed during operation on the pile loom, tuck-in is executed with a pick suitable for each terry mode, so that tuck-in mistakes are suppressed and a good-looking tuck-in ear is formed, and high A quality pile fabric can be obtained. Also, the terry mode and the tuck-in mode corresponding to the terry mode are both controlled in a programmable manner, and a pile fabric having a desired texture and a good-looking tuck-in ear are obtained by corresponding to the repetition of a plurality of different terry modes. be able to.

  If only one tuck-in mode is set for the same terry mode, the setting can be facilitated. In addition, even if the terry mode is the same, if a different tuck-in mode is set for a specific terry mode, weaving conditions such as weft type, fabric structure, density, etc., even in the same terry mode Can be set to the optimum tack-in mode according to the weaving conditions.

Including.

  As a method for inputting control data, in this embodiment, terry mode information is input to the steps constituting one unit pile formation cycle. For example, in the example of FIG. 5, terry mode 2L1F information is input to steps 1 to 6, terry mode 3L2F information is input to steps 7 to 11, and terry mode 2L1F information is input to steps 12 to 14, respectively. Then, information on the terry mode 3L1F is input to each of the steps 15 to 22, and information on the terry mode 2L2F is input to each of the steps 23 to 26. Enter the terry mode information. The setter 14 is automatically set with a pick at each step of a unit weaving cycle, that is, a loose pick or a first pick. That is, loose pick in steps 1, 2, 4, 5, 7, 8, 9, 12, 13, 15, 16, 17, 19, 20, 21, 23, 24, steps 3, 6, 10, 11, First picks at 14, 18, 22, 25, and 26 are automatically set.

  As another control data input method, the terry mode and the number of repetitions until a unit weaving cycle is configured may be input in the weaving order. For example, in the example of FIG. 5, the terry mode 2L1F is input twice, the terry mode 3L2F once, the terry mode 2L1F once, the terry mode 3L1F twice, and the terry mode 2L2F once. Accordingly, as in the above-described method, the picker at each step of one unit weaving cycle, that is, a loose pick or a first pick is automatically set in the setting device 14.

  Further, as a method of inputting further control data, a loose pick or a first pick may be input for each of steps 1 to 26 forming a unit weaving cycle. For example, in the example of FIG. 5, based on the information that the terry mode 2L1F is repeated twice in steps 1 to 6, a loose pick is input in steps 1, 2, 4, and 5, and a first pick is input in steps 3 and 6. . Based on the information that the terry mode 3L2F is woven once in steps 7 to 11, a loose pick is input to steps 7, 8, and 9, and a first pick is input to steps 10 and 11. Based on the information that the terry mode 2L1F is woven once in steps 12 to 14, a loose pick is input to steps 12 and 13, and a first pick is input to step 14.

Based on the information that the terry mode 2L2F is woven once in steps 23 to 26, a loose pick is input in steps 23 and 24, and a first pick is input in steps 25 and 26.

  As shown in the table of FIG. 4, the setter 14 has a NO. Applied to the terry mode 2L1F. No. 1 applied to 1 tuck-in mode and terry mode 2L2F No. 2 applied to 2-tuck-in mode and terry mode 3L1F No. 3 applied to 3 tuck-in mode, terry mode 2L3F No. 4 applied to 4 tuck-in mode, terry mode 3L2F No. 5 applied to 5 tuck-in mode and terry mode 4L1F No. 6 applied to 6 tuck-in mode, terry mode 2L4F No. 7 applied to 7 tuck-in mode, terry mode 3L3F No. 8 applied to 8 tuck-in mode and terry mode 4L2F Nine tuck-in modes are registered, and only one tuck-in mode is registered for each terry mode of a plurality of different terry modes, and these registered tuck-in modes form one unit of pile formation. The number of picks in the cycle and at least one of the specific picks that are tucked in during the cycle are different from each other. NO. In the 1 tuck-in mode, 3 picks are registered as the number of picks in one unit pile formation cycle, and 1 L, that is, the first loose pick is registered as a specific pick to be tucked in during the pile formation cycle. NO. In the 2-tuck-in mode, the number of picks in one unit pile formation cycle is 4 picks, and the specific picks that are tucked in during the pile formation cycle are the first L and second F, that is, the first loose pick and the second first pick. Two picks are registered respectively. In the other tack-in modes, the number of picks in one unit pile formation cycle and a specific pick to be tacked in during the pile formation cycle are registered.

  In the present embodiment, as shown in the table of FIG. 4, only one tuck-in mode is registered for one terry mode, so that the execution time, that is, the steps to be executed are different from each other. In the same terry mode, one tuck-in mode is always set and the tuck-in mode is specified. Therefore, in the present embodiment, the operation for setting the tack-in mode as the control data for each terry mode can be omitted because the tuck-in mode is automatically set as the control data in accordance with the setting of the terry mode. That is, with the setting of the terry mode, for the terry mode 2L1F in steps 1-6 and 12-14, the tuck-in mode in which tuck-in is executed with the first loose pick, and for the terry mode 3L2F in steps 7-11 Is a tuck-in mode in which tuck-in is performed with the first, third loose pick, and second first pick, tick-in with the first and third loose picks for the terry mode 3L1F in steps 15 to 22, and terry in steps 23 to 26 For the mode 2L2F, a tuck-in mode for executing a tuck-in by the first loose pick and the second first pick is set. As a result, as indicated by a check mark in the table of FIG. 5, the tuck-in is executed as control data in steps 1, 4, 7, 9, 11, 12, 15, 17, 19, 21, 23, and 26. Is set.

  In the setting device 14, the operation pick in the weft cutting mode, that is, the pile forming cycle of one unit of the counter yarn feeding side cutter 2 is set as control data, and is sucked and held by the ejector 4. In the set step, the weft ends Ya are cut by the counter feed yarn cutter 2 one or more at a time, and are cut to a certain length until they are tucked in at the latest.

  In steps 27 and later, by setting the number of repetitions of one unit of weaving cycle, loose pick or first pick in each step, execution or non-execution of tuck-in, and operation or non-operation of the counter-feeding cutter 2 are performed. Operation is set automatically.

  Based on the step signal from the mode selection control device 11, the setter 14 reads, from the control data, loose pick or first pick, execution or non-execution of tuck-in, and operation or non-operation of the counter yarn feeding side cutter 2, A loose pick signal or a first pick signal is output to the mode selection control device 11, and a tack-in execution signal and a weft cutting signal are output in the tuck-in execution step and the counter feed yarn cutter 2 operation step. Is output.

  The mode selection control device 11 branches and outputs the spindle rotation angle signal from the main control device 16 to the terry control device 15 as a terry motion control device, and also outputs a loose pick signal or a first pick signal from the setting device 14. Is output. Further, the mode selection control device 11 branches and outputs the spindle rotation angle signal from the main control device 16 to the tuck-in control device 10, and executes or does not execute tuck-in from the setting device 14, and counter feed yarn. Based on the operation or non-operation signal of the side cutter 2, a tuck-in execution signal and a weft cutting signal are output.

  In this embodiment, the loom moving device 17 is provided as a terry motion member, and the servo motor SM is provided as a dedicated actuator for driving the terry motion member and drives the loom moving device 17. The terry control device 15 as the terry motion control device controls the rotation angle of the servo motor SM based on the loose pick signal or the first pick signal from the mode selection control device 11 and the spindle rotation angle signal. That is, the terry control device 15 is based on the previous pick signal (loose pick signal or first pick signal), and when the current pick signal is shifted from the loose pick to the loose pick, the transition is from the loose pick to the first pick. The first pick signal, the first pick signal at the time of transition from the first pick to the first pick, and the loose pick signal at the time of transition from the first pick to the loose pick are determined. In the case of the first pick signal when moving from the loose pick to the first pick and the loose pick signal when moving from the first pick to the loose pick as described in the table of FIG. When the rotation angle is reached, the servo motor SM is driven to set the rotation angle of the servo motor SM to a predetermined value.

  As a result, the woven fabric C is transferred from the loose pick to the first pick (step indicated as advance in the table of FIG. 5) and from the first pick to the loose pick (FIG. 5). The step described in the table as “reverse”), when the main spindle rotation angle is reached, it moves so as to approach and match the striking position and to move away from the striking position. The so-called complete beating is executed in the beating of the ball, and the so-called partial beating is executed in the loose picking. In particular, the warp of the first first pick transferred from the loose pick, that is, the strike of the first first pick, causes the warp W to form a loop and form a pile.

  The tack-in control device 10 operates the air-type tack-in device 30 based on the tack-in execution signal, the weft cutting signal, and the main shaft rotation angle signal from the mode selection control device 1, that is, an electromagnetic wave connected to a high-pressure air supply source (not shown). The on-off valves 7, 8, 9 are opened when a predetermined main shaft rotation angle is reached, and high pressure air is supplied to the tack-in nozzle 1 a, auxiliary nozzle 1 b and gripping nozzle 1 c to inject air. Further, the tack-in control device 10 excites the rotary solenoid 3 to operate the counter yarn feeding side cutter 2 when a predetermined main shaft rotation angle is reached based on the input weft cutting signal and main shaft rotation angle signal.

  FIG. 2 shows a state in which one unit pile forming cycle is a weft insertion of three weft yarns, that is, a state of weaving a three pick pile formed by three picks, and the terry mode is 2 loose. Pick, 1st pick, that is, 2L1F is selected, and shows the state when weft Y is inserted in the second loose pick. Similarly to the yarn feeding side cutter 12, the counter yarn feeding side cutter 2 is driven at every rotation of the loom at a predetermined main shaft rotation angle, for example, 35 °, and the weft end Ya is cut to a predetermined length. Until it is tucked in, it is locked in the gripping hole 1d by the air jetted from the gripping nozzle 1c toward the gripping hole 1d. In the weft cutting mode of this embodiment, the counter yarn feeding side cutter 2 is driven at a predetermined main shaft rotation angle, for example, 35 °, and cuts the weft ends Ya one by one, like the yarn feeding side cutter 12. However, it is also possible to reduce the number of operations of the counter yarn feeding side cutter 2 by cutting a plurality of weft ends Ya together at a predetermined pick in the pile forming cycle. This is effective when the weft Y is a thin yarn, and the number of operations of the counter-feeding cutter 2 can be reduced without causing a cutting error.

  In the example shown in the table of FIG. 5, terry mode 2L1F, that is, 2 loose pick, 1 first pick pile formation in steps 1-6 and steps 27-32 after one unit weaving cycle of steps 1-6. The cycle is set, and three weft ends Ya are tucked together in the first L, that is, the first loose pick. 1 tuck-in mode is set. As described in the table of FIG. 5, in the first loose pick step, the servo motor SM has a complete spindle rotation Cc that is completely beaten as described above at a predetermined spindle rotation angle, for example, 60 °. The rotation angle at the complete beating position is changed to the rotation angle at the partial beating position so as to move from the beating position to the partial beating position to be a partial beating and to move backward with respect to the beating 6.

  In Steps 1, 4, 27, and 30, tuck-in is executed as marked by "Le", and in Steps 4 and 30, each weft of the first loose pick and the second loose pick in the previous pile formation cycle is executed. The end Ya is locked to the gripping hole 1d by the air sprayed from the gripping nozzle 1c toward the gripping hole 1d, and the injection of air from the gripping nozzle 1c is stopped, and the auxiliary nozzle 1b and auxiliary Following the nozzle 1b, air is ejected from the tack-in nozzle 1a at a predetermined main shaft rotation angle. Thereby, each weft end Ya of the first loose pick and the second loose pick is folded back to the woven fabric C together with the weft end Ya of the first first pick immediately after cutting by the cutter 2, Then, it is inserted into the warp opening that spreads from the pre-weaving Cc to the delivery side, that is, tucked in. As described in the table of FIG. 5, in the first first pick step, at a predetermined main shaft rotation angle, for example, 60 °, the servo motor SM advances the pre-weaving Cc with respect to the kite and moves the partial kite. The rotation angle at the partial strike position is changed to the rotation angle at the complete strike position so as to move from the strike position to the complete strike position. The three weft ends Ya that have been tucked in by the first hit of the first pick and the wefts Y of the first loose pick, the second loose pick, and the first first pick are beaten by the front weave Cc and completely It is beaten to form a new pre-woven Cc of the woven fabric C, and a tuck-in ear Cb is formed on the woven fabric C.

  In this way, the weft end Ya of the previous pile forming cycle is tucked in by the first loose pick, and more specifically, it is folded back and tucked in when the weft Y of the first loose pick is inserted. Since the weft end Ya is tucked in by the first loose pick, the pre-weaving Cc moves backward relative to the reed 6 and moves relative to the tack-in nozzle 1a. Accordingly, the insertion space of the weft end Ya formed in the warp opening connected to the moving weft Cc is expanded, and the weft end Ya is easily tucked in. In any of the terry modes, the weft end Ya is not tucked in when the weft Y of the first first pick is inserted. At the time of weft insertion of the first first pick weft Y, the weaving front Cc is moving from the partially beaten position to the fully beaten position toward the kite 6, and the warp opening is that of the loose pick previously inserted. The yarn is restricted by the weft Y and spreads from the weft Y toward the reed 6 and moves toward the reed 6 along with the movement of the cloth Cc and moves relative to the tack-in nozzle 1a. Accordingly, when tucking in when the weft Y of the first first pick is inserted, the weft end Ya is inserted into the insertion space of the reduced weft end Ya, resulting in the weft end Ya not being inserted into the warp opening. It is not preferable because a tack-in mistake is likely to occur. According to the present invention, since the tack-in mode is registered in the setting device 14 by eliminating the tack-in mode in which the tack-in is performed in an unpreferable pick of one unit pile formation cycle, the tack-in mistake can be avoided. A high quality woven fabric can be obtained.

  In the setter 14, as control data, a terry mode, a tuck-in mode, and a weft cutting mode are set for each step of weft insertion, and a moving amount of the woven cloth C, that is, a driving amount of the servo motor SM is set. May be. For example, in the terry mode that has a large number of loose picks such as 5L2F and 6L1F that are not registered in the setting device 14 in this embodiment, the woven cloth C may be moved in multiple times. You may divide into 1st loose pick and 3rd loose pick, respectively, and may move by 1/2 each. The pile formed by the subsequent first first picking is formed with two peaks, and the woven fabric C has a special texture.

  6 and 7 show a second embodiment according to the present invention. FIG. 6 is a table showing the tuck-in mode for each terry mode registered in the setting device 14, and two tuck-in modes are registered for each terry mode except for the terry mode 3L3F. FIG. 7 is a table showing an example of control data set in the setting device 14. In this embodiment, except for the terry mode 3L3F, a plurality of tuck-in modes are registered for each terry mode. Therefore, it is necessary to set the tuck-in mode for each terry mode as control data. In the example, different tuck-in modes are set for specific terry modes that are executed at different times in the same terry mode. That is, in the example of FIG. 7, the terry mode 2L1F is set as a specific terry mode that is executed at different times in the same terry mode, and for the terry mode 2L1F, steps 1 to 6 and steps 12 to 14 are mutually connected. Each time is set at a different time, that is, a different step. 1 tuck-in mode and NO. Different tack-in modes of the two tack-in modes are set. Thereby, even in the same terry mode, when weaving conditions such as different weft types are different, a tuck-in mode suitable for the weaving conditions is set as control data.

  8 and 9 show a third embodiment of the present invention, which is applied to a hammering position change type pile loom. The striking position change type pile loom has a striking member (not shown) for directly driving the scissors 6 using a link mechanism as a terry motion member, and a servo motor SM is provided as a dedicated actuator for driving the striking member. . In the first pick, the rotation angle of the servo motor SM is set to be large, and when the rivet is beaten, the heel 6 reaches the pre-weaving Cc of the woven fabric C, which is a so-called complete beating. In the loose pick, the rotation angle of the servo motor SM is set to be small. At the time of hammering, the hammer 6 does not reach the pre-weaving Cc of the woven fabric C, so-called partial hammering. After partial beating, the warp opening extends to the heel side while being regulated by the loose picked weft Ya. After complete beating, the warp opening as the insertion space of the weft end Ya spreads toward the heel side from the pre-weaving Cc, whereas after partial beating, the warp opening as the insertion space becomes the loose pick weft Ya. The upper warp and the lower warp produced by the restriction are spread from the crossing position toward the delivery side, move to the delivery side after complete beating, and it becomes difficult to tack-in by the tack-in nozzle 1a. Therefore, in the next pick after the first pick, that is, the first loose pick, the second first pick, the third first pick,..., The tuck-in is surely executed, while the next pick after the loose pick, that is, In the second loose pick, the third loose pick,..., The first first pick, a weft end Ya that is not inserted into the warp opening is likely to occur, which is not preferable. In this embodiment, since the tack-in mode is registered in the setting device 14 by eliminating the tack-in mode in which the tack-in is performed in an unpreferable pick of one unit pile formation cycle, it is possible to avoid a tack-in error.

  FIG. 8 is a table showing the tuck-in modes for each terry mode registered in the setting device 14, and a plurality of different tuck-in modes are registered depending on the terry mode as in the second embodiment.

  FIG. 9 is a table showing the control data set in the setting device 14. Depending on the terry mode, a plurality of different tuck-in modes are registered, so it is necessary to set the tuck-in mode for each terry mode as control data. In the example of FIG. Different tuck-in modes are set for specific terry modes executed at different times. That is, in the example of FIG. 9, the terry mode 2L2F and the terry mode 2L3F are set as specific terry modes that are executed at different times in the same terry mode. The terry mode 2L2F is set at different times of steps 1 to 8 and steps 19 to 22, that is, different steps. 2-tuck-in mode and NO. Different tack-in modes of the three tack-in modes are set respectively. Thereby, even in the same terry mode, when weaving conditions such as different weft types are different, a tuck-in mode suitable for the weaving conditions is set as control data. Similarly to the terry mode 2L2F, the terry mode 2L3F is set at different times of steps 14 to 18 and steps 23 to 27, respectively, and NO. 6 tuck-in mode and NO. Different tack-in modes of the 5-tuck-in mode are set.

  In the control data shown in FIG. 9, in steps 1 to 8, terry mode 2L2F is set, and NO. Tack-in is set in two tuck-in modes, that is, the first loose pick and the second first pick. In steps 9 to 18, the terry mode 2L3F is set, and NO. Tack-in is set in the six tack-in modes, that is, the first loose pick and the second first pick. In steps 19 to 22, the terry mode 2L2F is set, and NO. Tack-in is set only in the three-tuck ink-in mode, that is, only in the first loose pick, and four weft ends Ya are tucked together. Tacking in a large number of weft ends Ya in this way is applied when the weft Y is thin or the like, and even if a large number of weft ends are tucked in, the unevenness of the tuck-in ear Cb becomes large and the appearance is poor. Applies when there is nothing. In Steps 23 to 27, the terry mode 2L3F is set, and no. Tack-in is set in five tuck-in modes, that is, the first loose pick, the second first pick, and the third first pick. Steps 1 to 27 are one unit weaving cycle, and the steps after step 28 are set by the number of repetitions of one unit weaving cycle, so that loose pick or first pick in each step, execution or non-execution of tuck-in, The operation or non-operation of the counter yarn feeding side cutter 2 is automatically set.
