Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a warp tying machine. Background Art
[0002] In the related art, a warp tying machine is used to connect the warp yarns that are about to run out on a loom and the warp yarns on a new warp beam by tying knots, so that the loom can continue production. The yarn taking device of the warp tying machine includes two parts fixedly connected to each other. When the yarn taking device approaches the yarn curtain, each part of the yarn taking device can take out a yarn from the yarn curtain to prepare for the knotting step in the subsequent process. However, in the existing yarn taking device, during the yarn taking process, due to process errors or yarn quality, a certain part of the yarn taking device may take multiple yarns or fail to take any yarns in one yarn taking step; when multiple yarns are taken, the multiple taken yarns will be tied together with the yarn taken by the other part of the yarn taking device, and the tied yarn may be uneven in thickness, thus affecting the subsequent process and the weaving effect; when a part of the yarn taking device fails to take a yarn, the other part will release the taken yarn because it cannot tie a knot, and then take the yarn that has been taken during the subsequent yarn taking process of the yarn taking device until both parts of the yarn taking device take yarns. The repeated taking of the same yarn by the yarn taking device in the above process will damage the yarn, resulting in a decrease in the quality of the yarn and also affecting the subsequent process and the weaving effect. Summary of the Utility Model

For this purpose, the utility model provides a warp tying machine, which can avoid the negative impact on the weaving effect caused by too many or too few yarns taken by the yarn taking device, thereby enhancing the working stability of the warp tying machine.
[0004] The warp tying machine according to the first aspect embodiment of the utility model is used to take and tie the yarns on the yarn curtain in the first direction of the warp tying machine, and includes:
[0005] A frame;
[0006] 14. The yarn taking device of claim 13, wherein the first yarn taking module and the second yarn taking module are both movably connected to the frame; the first yarn taking module has a first predetermined position and a first yarn taking position, the first yarn taking position being located on one side of the first predetermined position in the first direction, the first yarn taking module being able to take yarn when moving from the first predetermined position to the first yarn taking position, and being able to release yarn during the process of moving from the first yarn taking position to the first predetermined position; the second yarn taking module having a second predetermined position and a second yarn taking position, the second yarn taking position being located on one side of the first predetermined position in the first direction, the second yarn taking module being able to take yarn when moving from the second predetermined position to the second yarn taking position, and being able to release yarn during the process of the second yarn taking module moving from the second yarn taking position to the second predetermined position;

[0008] A detection device, wherein the detection device signal is connected to the first driving module and the second driving module, and the detection device is used to detect the yarn taking quantity of the first yarn taking module and the second yarn taking module; the first driving module drives the first yarn taking module to move to the first predetermined position and enter the first in-place state when the yarn taking quantity detected by the detection device is equal to the first preset quantity, and drives the first yarn taking module to take yarn again after releasing the yarn when the yarn taking quantity of the first yarn taking module detected by the detection device is not equal to the first preset quantity; the second driving module drives the second yarn taking module to move to the second predetermined position and enter the second in-place state when the yarn taking quantity of the second yarn taking module detected by the detection device is equal to the second preset quantity, and drives the second yarn taking module to take yarn again after releasing the yarn when the yarn taking quantity detected by the detection device is not equal to the second preset quantity;
[0009] A knotting device is used for knotting the yarn taken by the first yarn taking module and the yarn taken by the second yarn taking module when the first yarn taking module is in the first position and the second yarn taking module is in the second position.
[0010] According to the warp tying machine of the embodiment of the present utility model, it has at least the following beneficial effects: The driving module can drive the yarn taking module to move back and forth between a predetermined position and a yarn taking position, and when the yarn taking module moves from the predetermined position to the yarn taking position, it can approach the yarn on the yarn curtain and take the yarn. During the process of the yarn taking module moving from the yarn taking position to the predetermined position, it can release the yarn. Then both the first yarn taking module and the second yarn taking module can perform repeated yarn taking operations. The detection device is used to detect the number of yarns taken by the first yarn taking module and the second yarn taking module. The first driving module drives the first yarn taking module to move to a first predetermined position and enter a first in-position state when the number of yarns taken detected by the detection device is equal to a first preset number, and drives the first yarn taking module to release the yarn and then take the yarn again when the number of yarns taken detected by the detection device is not equal to the first preset number.

Since the first yarn taking module and the second yarn taking module are respectively driven by different driving modules, when the number of yarns taken by one yarn taking module is not the preset number, it will not affect the other yarn taking module to enter the in-position state, thereby avoiding the repeated yarn taking operation of the yarn by a certain yarn taking module when the other yarn taking module does not take the correct number of yarns, and further avoiding the wear of the yarn during the repeated yarn taking process. The knotting device of the warp tying machine can knot the yarn taken by the first yarn taking module and the yarn taken by the second yarn taking module after each yarn taking module enters the in-position state. Since each yarn taking module needs to enter its respective in-position state after taking the corresponding preset number of yarns, the situation that the warp tying machine knots yarns with the number not matching the preset number can be avoided, enhancing the consistency of the knotting process, and further enhancing the working stability of the warp tying machine.

When the number of yarns taken detected by the first identification module is not equal to the first preset number, the first driving module drives the first yarn taking module to release the yarn and then take the yarn again. The second identification module is used to detect the number of yarns taken by the second yarn taking module. The second driving module can drive the second yarn taking module to move to the second predetermined position and enter the second in-position state or drive the second yarn taking module to release the yarn and then take the yarn again according to the number of yarns taken detected by the second identification module.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
[0040] Please refer to Figures 1-4 as shown, where Figure 1 , Figure 2The first yarn taking module 210 is located at a first predetermined position, and the second yarn taking module 220 is located at a second predetermined position; the utility model discloses a warp tying machine 20, which can tying the warp curtain 10 in the first direction (i.e. Figures 1-4 The utility model warp tying machine 20 comprises a frame 100, a yarn taking device 200, a driving device 300, a detection device 400 and a knotting device 500.
[0041] The yarn taking device 200 includes a first yarn taking module 210 and a second yarn taking module 220; the first yarn taking module 210 and the second yarn taking module 220 are both movably connected to the frame 100; the first yarn taking module 210 has a first predetermined position and a first yarn taking position, the first yarn taking position is located on one side of the first predetermined position in the first direction, the first yarn taking module 210 can take yarn when moving from the first predetermined position to the first yarn taking position, and can release yarn in the process of moving from the first yarn taking position to the first predetermined position; the second yarn taking module 220 has a second predetermined position and a second yarn taking position, the second yarn taking position is located on one side of the second predetermined position in the first direction, the second yarn taking module 220 can take yarn when moving from the second predetermined position to the second yarn taking position, and can release yarn in the process of moving from the second yarn taking position to the second predetermined position.
[0042] Those skilled in the art can realize the yarn taking and releasing actions of the yarn taking module of the utility model according to the yarn taking structure commonly used in the prior art. For example, in some embodiments, the yarn taking module includes a clamping jaw that can be opened and closed and a connecting rod mechanism that is connected to the clamping jaw with a transmission; when in a predetermined position, the clamping jaw of the yarn taking module is in an open state; in the process of the entire yarn taking module moving from the predetermined position to the yarn taking position along the first direction, the connecting rod mechanism drives the opened clamping jaw to close and clamp the yarn 11 on the thread curtain 10 to take the yarn; when the entire yarn taking module moves back to the predetermined position from the yarn taking position in the reverse direction of the first direction, the connecting rod mechanism drives the clamping jaw to open and release the yarn. In other embodiments, the yarn taking module includes a clamping jaw and a servo motor that is connected to the clamping jaw with a transmission, and the servo motor drives the clamping jaw to open in the process of the entire yarn taking module moving from the predetermined position to the yarn taking position along the first direction, and drives the clamping jaw to close when the entire yarn taking module moves back to the predetermined position from the yarn taking position in the reverse direction of the first direction.
[0043] As a preferred method of taking yarn, in some embodiments, the first yarn taking module 210 includes a suction nozzle, and when the first yarn taking module 210 moves from the first predetermined position to the first yarn taking position, the suction nozzle can suck the yarn 11; through the above scheme, compared with the traditional scheme of using a clamp to clamp the yarn 11, using a suction nozzle to suck the yarn 11 can avoid the mechanical structure in the first yarn taking module 210 causing wear to the yarn 11 during the yarn taking process, thereby ensuring the quality of the yarn 11 taken by the first yarn taking module 210. In other embodiments, the second yarn taking module 220 includes a suction nozzle, and when the second yarn taking module 220 moves from the second predetermined position to the second yarn taking position, the suction nozzle can suck the yarn 11, and the above scheme can correspondingly ensure the quality of the yarn 11 taken by the second yarn taking module 220.
[0044] The utility model uses a driving device 300 to drive the yarn taking module to move between the predetermined position and the yarn taking position. The driving device 300 includes a first driving module 310 and a second driving module 320. The first driving module 310 is connected to the first yarn taking module 210 by transmission, and the first driving module 310 can drive the first yarn taking module 210 to move back and forth between the first yarn taking position and the first predetermined position; the second driving module 320 can drive the second yarn taking module 220 to move back and forth between the second yarn taking position and the second predetermined position. Since the yarn taking module can take yarn when it moves from the predetermined position to the yarn taking position, and the yarn taking module can release yarn when it moves from the yarn taking position to the predetermined position, the driving device 300 can drive the first yarn taking module 210 and the second yarn taking module 220 to perform repeated yarn taking operations through different driving modules.
[0045] The detection device 400 is signal-connected to the first driving module 310 and the second driving module 320 , and is used to detect the yarn taking quantity of the first yarn taking module 210 and the second yarn taking module 220 .
[0046] Regarding the specific scheme of detecting the number of yarns by the detection device 400, in some embodiments, the detection device 400 includes a photoelectric gate module, which can count the yarns 11 passing through the photoelectric gate, and judge the number of yarns taken by the yarn taking module in one yarn taking process by the number of times the yarn 11 passes through the photoelectric gate when the yarn taking module moves from the yarn taking position to the predetermined position. In other embodiments, the detection device 400 includes a visual recognition module, which uses image recognition to identify the number of yarns 11 taken by the first yarn taking module 210 and the second yarn taking module 220; compared with other detection schemes of the detection device 400, the use of the visual recognition module to detect the number of yarns has a higher judgment accuracy.
[0047] It should be noted that the detection device 400 can identify the number of yarns taken by the first yarn taking module 210 and the second yarn taking module 220 respectively. Therefore, the first driving module 310 can be driven separately according to the number of yarns taken by the first yarn taking module 210 detected by the detection device 400, and the second driving module 320 can be driven separately according to the number of yarns taken by the second yarn taking module 220 detected by the detection device 400.
[0048] For the detection signal sent by the detection device 400, when the number of yarns taken by the yarn taking module detected by the detection device 400 is not equal to the preset number, the driving module drives the yarn taking module to release the yarn and then take the yarn again, so as to eliminate the situation where the number of yarns taken by the yarn taking module is incorrect due to unexpected situations. On the other hand, when the number of yarns taken detected by the detection device 400 is equal to the first preset number, the first driving module 310 drives the first yarn taking module 210 to move to the first predetermined position and enter the first in-position state; when the number of yarns taken by the second yarn taking module 220 detected by the detection device 400 is equal to the second preset number, the second driving module 320 drives the second yarn taking module 220 to move to the second predetermined position and enter the second in-position state. Since the first yarn taking module 210 does not perform the yarn releasing action after receiving the detection signal of the detection device 400, when the first yarn taking module 210 is in the first in-position state, it is not only located at the first predetermined position, but also remains in the state of having taken the yarn 11. Similarly, when the second yarn taking module 220 is in the second in-position state, it is located at the second predetermined position and remains in the state of having taken the yarn 11.
[0049] Since the first yarn taking module 210 and the second yarn taking module 220 are driven separately by different driving modules, when the number of yarns taken by one yarn taking module is not the preset number, it will not affect the other yarn taking module to enter the in-position state, thus avoiding the repeated yarn taking operation on the yarn 11 by one yarn taking module when the other yarn taking module does not take the correct number of yarns 11, and further avoiding the wear of the yarn 11 during the repeated yarn taking process.
[0050] When the first yarn taking module 210 is in the first in-position state and the second yarn taking module 220 is in the second in-position state, the knotting device 500 is used to knot the yarn 11 taken by the first yarn taking module 210 and the yarn 11 taken by the second yarn taking module 220. Please refer to Figure 1 As shown, the first yarn taking module 210 that has taken the yarn is located at the first predetermined position, and the second yarn taking module 220 that has taken the yarn is located at the second predetermined position, that is, the first yarn taking module 210 is in the first in-position state and the second yarn taking module 220 is in the second in-position state. The knotting device 500 arranged on the left side of the yarn taking device 200 can knot the yarns 11 of the first yarn taking module 210 and the second yarn taking module 220.
[0051] After each yarn taking module of the knotting device 500 of the warp tying machine 20 enters the in-place state, it can knot the yarn 11 taken by the first yarn taking module 210 and the yarn 11 taken by the second yarn taking module 220. Since each yarn taking module needs to enter its own in-place state after taking a yarn 11, the situation that the warp tying machine 20 knots multiple yarns 11 can be avoided, the consistency of the knotting process is enhanced, and further the working stability of the warp tying machine 20 is enhanced.
[0052] Without departing from the inventive concept of the present utility model, those skilled in the art can adjust the specific values of the first preset quantity and the second preset quantity according to actual needs to achieve different knotting effects of the warp tying machine 20.
[0053] Further, please refer to Figure 2 As shown, in some embodiments, the detection device 400 includes a first identification module 410 and a second identification module 420. The first identification module 410 is used to detect the quantity of yarn taken by the first yarn taking module 210. The first driving module 310 drives the first yarn taking module 210 to move to a first predetermined position and enter a first in-place state when the quantity of yarn taken detected by the first identification module 410 is equal to the first preset quantity, and drives the first yarn taking module 210 to release the yarn and then take the yarn again when the quantity of yarn taken detected by the first identification module 410 is not equal to the first preset quantity. The second identification module 420 is used to detect the quantity of yarn taken by the second yarn taking module 220. The second driving module 320 can drive the second yarn taking module 220 to move to a second predetermined position and enter a second in-place state or drive the second yarn taking module 220 to release the yarn and then take the yarn again according to the quantity of yarn taken detected by the second identification module 420. Through the above solution, the detection device 400 can detect the quantity of yarn respectively through the first identification module 410 and the second identification module 420, avoid the first driving module 310 driving the first yarn taking module 210 to act according to the quantity of yarn taken by the second yarn taking module 220, and avoid the second driving module 320 driving the second yarn taking module 220 to act according to the quantity of yarn taken by the first yarn taking module 210, thereby enhancing the working stability of the warp tying machine 20.
[0054] It has been mentioned above that the detection device 400 can detect the quantity of yarn through the visual recognition module included therein. As a preferred solution, both the first identification module 410 and the second identification module 420 are visual recognition modules. Using the visual recognition modules of the first identification module 410 and the second identification module 420 to detect the quantity of yarn can further improve the detection accuracy of the first identification module 410 and the second identification module 420.
[0055] Without departing from the inventive concept of the present utility model, those skilled in the art can adjust the specific position where the recognition module recognizes the number of yarns. It should be noted that the driving module should perform or stop yarn feeding according to the detection result of the recognition module only after the recognition module has completed detection, so as to avoid the recognition module being unable to recognize the yarn 11 taken by the yarn taking module.
[0056] Further, please refer to Figure 2 As shown, in some embodiments, the first recognition module 410 is arranged facing the first yarn taking module 210 located at the first predetermined position; the second recognition module 420 is arranged facing the second yarn taking module 220 located at the second predetermined position. Through the above solution, since the yarn taking module located at the predetermined position is far from the yarn 11 on the yarn curtain 10, the yarn on the yarn curtain 10 is not likely to interfere with the detection result of the recognition module, thereby further improving the detection accuracy of the first recognition module 410 and the second recognition module 420.
[0057] Further, in some embodiments, the first yarn taking module 210 further has a first detection position, and the second yarn taking module 220 further has a second detection position; in the first direction, the first detection position is located between the first predetermined position and the first yarn taking position, and the second detection position is located between the second predetermined position and the second yarn taking position; the first yarn taking module 210 passes through the first detection position during the process of moving from the first yarn taking position to the first predetermined position, and the first recognition module 410 is arranged facing the first yarn taking module 210 located at the first detection position; the second yarn taking module 220 passes through the second detection position during the process of moving from the second yarn taking position to the second predetermined position, and the second recognition module 420 is arranged facing the second yarn taking module 220 located at the second detection position. Compared with the solution where the recognition module detects the yarn taking module located at the predetermined position, the recognition module can recognize the number of yarns 11 taken by the yarn taking module earlier when detecting at the detection position, improve the efficiency of sending detection signals, and thus improve the overall working efficiency of the warping machine 20.
[0058] Further, please refer to Figure 2As shown, in some embodiments, the detection device 400 includes a plurality of first identification modules 410. The plurality of first identification modules 410 are all visual identification modules. The plurality of first identification modules 410 are arranged obliquely relative to each other. When the number of yarns detected by the plurality of first identification modules 410 is different, the first yarn taking module 210 is driven by the first driving module 310 to release the yarn and then take the yarn again. When only one first identification module 410 is provided, several yarns 11 taken by the first yarn taking module 210 may overlap when observed from a certain angle due to accidental factors, resulting in the number of yarns detected by a certain first identification module 410 observed from a certain angle being inconsistent with the actual number of taken yarns, and further possibly causing the first driving module 310 to perform incorrect actions. When a plurality of first identification modules 410 are provided, the number of yarns detected by a certain first identification module 410 observed from a certain angle will be inconsistent with the number of yarns detected by another first identification module 410. When the number of yarns detected by the plurality of first identification modules 410 is different, the first driving module 310 drives the first yarn taking module 210 to release the yarn and then take the yarn again, ignoring the influence of accidental factors and avoiding incorrect actions of the first driving module 310.
[0059] In some other embodiments, the detection device 400 includes a plurality of second identification modules 420. The plurality of second identification modules 420 are arranged obliquely relative to each other. When the number of yarns detected by the plurality of second identification modules 420 is different, the second driving module 320 drives the second yarn taking module 220 to release the yarn and then take the yarn again. The above solution can correspondingly avoid incorrect actions of the second driving module 320.
[0060] Further, please refer to Figure 2 、 Figure 3 As shown, in some embodiments, the first yarn taking module 210 is arranged above the second yarn taking module 220, and the first identification module 410 is arranged above the first yarn taking module 210; the second identification module 420 is arranged below the second yarn taking module 220. Since the yarn curtain 10 in the prior art usually has yarns 11 arranged in upper and lower layers, the above solution of arranging the first yarn taking module 210 and the second yarn taking module 220 in upper and lower positions respectively can be adapted to the yarn curtain 10 in the prior art. Arranging the first identification module 410 and the second identification module 420 on one side close to the corresponding yarn taking module also makes the identification result less likely to be affected by the yarns 11 taken by the other yarn taking module.
[0061] Further, the frame 100 includes a shielding portion 110 disposed between the first yarn taking module 210 and the second yarn taking module 220; in the up and down direction, the projections of the first yarn taking module 210, the second yarn taking module 220, and the shielding portion 110 overlap each other. Through the above solution, when the first identification module 410 detects the number of yarns of the first yarn taking module 210, the shielding portion 110 can shield the yarns 11 taken by the second yarn taking module 220, preventing the first identification module 410 from including the number of yarns of the second yarn taking module 220 in the total number of yarns taken by the first identification module 410; when the second identification module 420 detects the number of yarns of the second yarn taking module 220, the shielding portion 110 can shield the yarns 11 taken by the first yarn taking module 210, preventing the second identification module 420 from including the number of yarns of the first yarn taking module 210 in the total number of yarns 11 taken by the second identification module 420, thereby improving the detection accuracy of the first identification module 210 using the visual identification module and the second identification module 220 using the visual identification module.
[0062] As a preferred solution, a light source is provided inside the shielding portion 110 for illuminating the first yarn taking module 210 and the second yarn taking module 220. When the first identification module 410 detects the yarns 11 of the first yarn taking module 210, the light source inside the shielding portion 110 can illuminate the yarns 11 taken by the first yarn taking module 210 and the second yarn taking module 220, thereby improving the detection accuracy of the first identification module 210 using the visual identification module and the second identification module 220 using the visual identification module.
[0063] Further, please refer to Figure 1 、 Figure 4 As shown in the figures, in some embodiments, the warping machine 20 further includes a moving device 600 connected to the frame 100, and the moving device 600 can drive the frame 100 to move in the first direction after the knotting device 500 knots. Through the above solution, the moving device 600 can drive the driving device 300, the yarn taking device 200, and the detection device 400 on the frame 100 to move in the first direction, and the predetermined position and the yarn taking position of the yarn taking module also move the same distance in the first direction together with the moving device 600, so that the yarn taking module can take the remaining yarns 11 on the yarn curtain 10, and further enable the warping machine 20 to take and knot the remaining yarns 11 on the yarn curtain 10.
[0064] The above has described the embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
