Abstract
Description
Technical Field
[0001] This application relates to the field of textile equipment, and more particularly to a control method and apparatus for a false twist texturer. Background Technology
[0002] In the existing textile industry, a false-twist texturer is a machine that increases the elasticity of formed yarn. To stretch and false-twist the yarn, from the raw yarn to its winding after false-twist, a false-twist texturer typically includes, in sequence, a first conveying unit group, a first heating unit group, a cooling unit group, a false-twist device group, a second conveying unit group, a network pressurizing device group, an auxiliary second conveying unit group, and a winding device group. For example, at least one spindle in each of the first, second, and auxiliary second conveying unit groups (one spindle corresponds to one yarn, and each yarn passes through the first conveying unit, first heating unit, cooling unit, false-twist device, second conveying unit, network pressurizing device, auxiliary second conveying unit, and winding device during its forward movement) is equipped with a guide disc (godet) equipped with a motor. Thus, during yarn conveying, the overall controller sends an instruction signal to the motor of the guide disc at that at least one spindle, and the motor provides the rotational speed for yarn conveying.
[0003] Currently, after the false twist texturer is started up, before entering the production state, each yarn usually needs to be manually processed to start the yarn. That is, each yarn is hung at multiple transmission points that the yarn passes through during the conveying process, such as the first conveying device, the second conveying device, and the false twister.
[0004] It should be noted that the above description of the background technology is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background technology section of this application. Summary of the Invention
[0005] The inventors discovered that in the existing process of yarn starting process, since the false twist texturer enters a high-speed operation state at each transmission point after startup, manual starting process may be difficult, the success rate of starting process is low, and the time consumption is long, thus affecting the production efficiency of false twist texture process of yarn.
[0006] To address at least one of the aforementioned problems or other similar issues, embodiments of this application provide a control method and apparatus for a false twist texturer, which can improve the success rate of yarn start-up processing, thereby increasing the production efficiency of false twist texturer processing of yarn.

The control method includes: adjusting the draft ratio between the first conveying device and the second conveying device using a first controller that individually controls the motors at the at least one conveying device, based on received instruction information indicating that the false-twist texturing machine has entered the starting process; and setting the false-twist texturing machine to a production state based on received first instruction signal indicating that the starting process has been completed.
[0008] According to a second aspect of the present application, a control device for a false twist texturer is provided, wherein at least one of a first conveying device and a second conveying device, through which each yarn passes during its forward movement, is individually equipped with a motor. The control device includes: a first adjustment unit, configured to adjust the draft ratio between the first conveying device and the second conveying device using a first controller that individually controls the motors at the at least one conveying device, based on received indication information indicating that the false twist texturer has entered a starting state; and a setting unit, configured to set the false twist texturer to a production state based on received first indication signal indicating that the starting process has been completed.
[0009] The beneficial effects of the embodiments of this application are at least as follows: by adjusting the draft ratio between the first conveying device and the second conveying device using a first controller that individually controls the motor of at least one of the first and second conveying devices before the yarn is subjected to the yarn-making process, the transmission speed of the yarn to be subjected to the yarn-making process can be reduced, thereby increasing the success rate of the yarn-making process and thus improving the production efficiency of the yarn for false twisting and texturing.

[0023] The embodiments of this application will now be described with reference to the accompanying drawings.
[0024] First aspect of the embodiments
[0025] An embodiment of the first aspect of this application provides a control method for a false twisting deformation machine.
[0026] In current false twist texturers, the first conveying device group, the false twister group, and the second conveying device group are usually driven by a centralized motor during the conveying process of the yarn through them. However, in the embodiments of this application, at least one of the first conveying device group, the false twister group, and the second conveying device group is driven by a single electric motor. For a single-motor drive, a guide disc can be installed at each spindle position in the first and second conveyor groups. For example, the first and second conveyor groups each have 12 spindle positions (that is, the first conveyor group includes 12 first conveyors, and the second conveyor group includes 12 second conveyors; each spindle position corresponds to one yarn). Then, 12 guide discs are installed in the first and second conveyor groups respectively (guide disc Gt1 is installed in the first conveyor, and guide disc Gt2 is installed in the second conveyor). Each guide disc that each yarn passes through during its forward movement in the false twist texturer is equipped with a small motor (for example, with a power of approximately 40W). That is, each guide disc at each spindle position in the first and second conveyor groups of the false twist texturer is equipped with a motor (such a guide disc is called a godet). Each yarn must pass through at least two guide discs respectively located at the first and second conveyor groups, as well as the false twister, during its forward movement.
[0027] The above description specifies the case where guide discs are provided at the spindle positions in the first and second conveying device groups. However, this application is not limited to this. Any yarn conveying mechanism provided at each spindle position in the first and second conveying device groups can be included in this application. For example, in addition to providing guide discs at each spindle position in the first and second conveying device groups, each spindle position can also have a clamping roller structure with a separate motor, or any other conveying mechanism with a separate motor. In other words, this application can be realized by providing a separate motor for at least one of the first and second conveying devices that each yarn passes through during its forward movement.
[0028] In the embodiments of this application, a guide disc may be provided at at least one spindle position in the first conveying device and the second conveying device. That is, each yarn may be conveyed through one guide disc (e.g., a guide disc only provided in the second conveying device or a guide disc only provided in the first conveying device) or two guide discs (a guide disc provided in both the first and second conveying devices).
[0029] In the case where each yarn is conveyed through only one guide plate, the other conveying devices through which the yarn passes (e.g., the first conveying device and the auxiliary second conveying device) can be clamping roller structures. For example, if the guide plate is only provided at the second conveying device, then the yarn conveying structure of the first conveying device is a clamping roller structure; or, if the guide plate is only provided at the first conveying device, then the yarn conveying structure of the second conveying device is a clamping roller structure.
[0030] When each yarn is conveyed through two guide discs, the remaining conveying devices through which the yarn passes (e.g., an auxiliary second conveying device) can be clamping roller structures. For example, if guide discs are provided at both the first and second conveying devices, then the yarn conveying structure of the auxiliary second conveying device is a clamping roller structure.
[0031] Among them, the conveying device group equipped with guide rollers is collectively referred to as G (for example, the first conveying device group is G1, the second conveying device group is G2, etc.), and the conveying device group equipped with clamping rollers is collectively referred to as W.
[0032] The clamping roller mechanism is typically a centralized motor drive, meaning that instead of a separate motor for each spindle position on the conveying device, a single main motor provides centralized drive for all spindle positions. However, this application is not limited to this. For example, the clamping roller mechanism may also have a separate motor at each spindle position, with independent control of the motor at each spindle position.
[0033] The following description uses the guide disc as an example to illustrate the conveying mechanism at each spindle position in the first and second conveying device groups.
[0034] Figure 1 This is a schematic diagram of a control method for a false twisting texturing machine according to an embodiment of the first aspect of this application.
[0035] like Figure 1 As shown, the control method for a false-twist texturing machine may include:
[0036] 101. Based on received instruction information indicating that the false-twist texturing machine should enter the starting process, the draw ratio between the first and second conveying devices is adjusted using a first controller that individually controls the motors of at least one of the first and second conveying devices; and
[0037] 102. Based on the received first indication signal indicating that the raw head processing has been completed, the false twisting texturer is set to production state.
[0038] Therefore, according to the above embodiments, by adjusting the draft ratio between the first and second conveying devices using a first controller that individually controls the motors of at least one of the first and second conveying devices before the yarn start-up process, the transmission speed of the yarn requiring start-up process can be reduced, thereby increasing the success rate of the start-up process and thus improving the production efficiency of the yarn for false twisting and texturing.
[0039] In this embodiment, each yarn in the false-twist texturing machine needs to pass through at least one guide disc (at the first conveying device and / or the second conveying device) during its forward movement. Each guide disc's motor is equipped with a controller (the controllers of the motors at the first and second conveying devices are referred to as the first controller). That is, the first controller has a one-to-one relationship with the motor; the first controller individually controls the motor connected to it, thus each guide disc is individually driven by its connected first controller. Such a guide disc with an individually configured controller is called a smart godet.
[0040] In the embodiments of this application, the controller can be implemented by, for example, a PLC, which can be electrically connected to the motor or integrated with the motor.
[0041] In this embodiment of the application, the controller configured on each motor can obtain instruction signals from the main controller of the false twist texturing machine, thereby controlling the speed of the motor connected to it, and can also feed back the operating parameters of the motor connected to it to the main controller of the false twist texturing machine, such as the current value and voltage value of the motor.
[0042] In this embodiment, after adjusting the draft ratio between the first and second conveying devices in step 101, the operator can be informed in various ways that the manual topping process can begin. For example, the main controller issues a command signal to instruct the operator that the false twisting machine can enter the manual topping process (e.g., the main controller can issue a command signal by issuing a flashing light indicator, a display command, or a voice command). At this time, the manual topping process begins. Alternatively, the operator can directly enter the manual topping process within a predetermined time (e.g., 5 seconds) after issuing the command to adjust the draft ratio between the first and second conveying devices (e.g., the second indication signal hereinafter). After the manual topping process is completed, the main controller receives a feedback signal (first indication signal) indicating that the topping process is complete.
[0043] In this embodiment, since there is a speed difference between the first conveying device and the second conveying device, for example, the speed at the transmission point of the first conveying device is usually lower than the speed at the transmission point of the second conveying device, there is a draw ratio between the first conveying device and the second conveying device. By adjusting the draw ratio between the first conveying device and the second conveying device, there is no excessive draw between the first conveying device and the second conveying device, which is beneficial to the operation of the head processing.
[0044] Figure 2 yes Figure 1 A schematic diagram illustrating the specific implementation method of step 101.
[0045] like Figure 2 As shown, adjusting the draw ratio between the first conveying device and the second conveying device (step 101) may include:
[0046] 201, sending a second indication signal to indicate the adjustment of the draw ratio between the first conveying device and the second conveying device; and
[0047] 202. According to the second indication signal, reduce the rotation speed of the second conveying device and / or increase the rotation speed of the first conveying device so that the draw ratio between the first conveying device and the second conveying device is adjusted to a preset draw ratio.
[0048] In this embodiment of the application, in 201, for example, after receiving the instruction information that the false twist texturer is entering the starting process, the main controller of the false twist texturer can send a signal (second instruction signal) to the first controller of the motor at the first conveying device and / or the second conveying device to adjust the draw ratio between the first conveying device and the second conveying device.
[0049] Specifically, when a guide roller is provided at the first conveying device (e.g., a guide roller is provided only at the first conveying device, or a guide roller is provided at both the first and second conveying devices), the main controller can send a second indication signal to the first controller of the motor of the guide roller at the first conveying device. Then, in step 202, the first controller of the motor of the guide roller at the first conveying device increases the speed of the motor of the guide roller at the first conveying device according to the signal. Alternatively, when a guide roller is provided at the second conveying device (e.g., a guide roller is provided only at the second conveying device, or a guide roller is provided at both the first and second conveying devices), the main controller can send a second indication signal to the first controller of the motor of the guide roller at the second conveying device. If an indication signal is received, in step 202, the first controller of the guide roller motor at the second conveying device reduces the speed of the guide roller motor at the second conveying device according to the signal. Alternatively, if guide rollers are provided at both the first and second conveying devices, the main controller can send a second indication signal to both the first controller of the guide roller motor at the first conveying device and the first controller of the guide roller motor at the second conveying device. In this case, in step 202, the first controller of the guide roller motor at the first conveying device increases the speed of the guide roller motor at the first conveying device according to the signal, and simultaneously, in step 202, the first controller of the guide roller motor at the second conveying device decreases the speed of the guide roller motor at the second conveying device according to the signal. This achieves the purpose of adjusting (reducing) the draw ratio between the first and second conveying devices.
[0050] In this embodiment of the application, before the raw yarn processing, the draft ratio between the first conveying device and the second conveying device needs to be adjusted to a pre-set draft ratio. For example, the pre-set draft ratio can be pre-set according to the different yarn varieties.
[0051] Figure 3 yes Figure 1 A schematic diagram illustrating the specific implementation method of step 102.
[0052] like Figure 3 As shown, setting the false-twist texturing machine to production status (step 102) may include:
[0053] 301, Send a third indication signal to indicate that the false twist texturing machine has entered the production state;
[0054] 302. According to the third indication signal, increase the speed of the second conveying device and / or decrease the speed of the first conveying device so that the draw ratio between the first conveying device and the second conveying device is adjusted to the production state draw ratio.
[0055] In this embodiment of the application, in 301, for example, the main controller can send a third indication signal to the first controller of the motor of the guide disc at the first conveying device and / or the first controller of the motor of the guide disc at the second conveying device, based on the acquired first indication signal, to indicate that the false twist texturing machine has entered the production state.
[0056] Specifically, if in step 202 the draw ratio between the first and second conveying devices is adjusted by increasing the speed of the guide roller motor at the first conveying device, then the main controller can send a third instruction signal to the first controller of the guide roller motor at the first conveying device. In step 302, the first controller of the guide roller motor at the first conveying device will then reduce the speed of the guide roller motor at the first conveying device according to this signal. Alternatively, if in step 202 the draw ratio between the first and second conveying devices is adjusted by decreasing the speed of the guide roller motor at the second conveying device, then the main controller can send a third instruction signal to the first controller of the guide roller motor at the second conveying device. In step 302, the first controller of the guide roller motor at the second conveying device will then reduce the speed of the guide roller motor at the second conveying device according to this signal. The controller can either increase the speed of the guide roller motor at the second conveyor, or, if in step 202 the draw ratio between the first and second conveyors is adjusted by both decreasing the speed of the guide roller motor at the second conveyor and increasing the speed of the guide roller motor at the first conveyor, then the main controller can send a third instruction signal to both the first controller of the guide roller motor at the first conveyor and the first controller of the guide roller motor at the second conveyor. In step 302, the first controller of the guide roller motor at the first conveyor will decrease the speed of its motor according to the signal, and simultaneously, in step 302, the first controller of the guide roller motor at the second conveyor will increase the speed of its motor according to the signal. This achieves the goal of adjusting the draw ratio between the first and second conveyors to the normal production draw ratio.
[0057] In this embodiment of the application, each yarn in the false twist texturer needs to pass through a false twister during its forward movement. Alternatively, each false twister that the yarn passes through during its forward movement can be equipped with a separate motor, and the motor at the false twister is also equipped with a controller to control it individually (the controller of the motor at the false twister will be referred to as the second controller). That is to say, the second controller and the motor at the false twister have a one-to-one relationship. The second controller controls the motor connected to it individually, so each false twister is driven individually by the second controller connected to it.
[0058] In the embodiments of this application, for certain special yarn products, simply adjusting the draw ratio between the first and second conveying devices may not be sufficient to effectively improve the efficiency of raw yarn processing, for example, for fine denier porous yarn. In this case, such as Figure 1 As shown, prior to step 102, the control method may further include:
[0059] 103. Based on the received instruction information, a fourth instruction signal is sent to instruct the speed of the false twister in the false twist forming machine to be reduced, so as to reduce the speed of the false twister to a preset speed by using a second controller that individually controls the motor located at the false twister.
[0060] Therefore, for certain special yarn products (e.g., fine denier porous yarn), by adjusting the draw ratio between the first and second conveying devices and reducing the speed of the motor at the false twister, the efficiency of the raw yarn processing can be improved.
[0061] In this embodiment of the application, in step 103, for example, after receiving the instruction information that the false twisting machine has entered the starting process, the main controller of the false twisting machine can also send a signal (fourth instruction signal) to the second controller of the motor at the false twister to reduce the speed of the motor at the false twister; the second controller of the motor at the false twister reduces the speed of the motor at the false twister according to the signal.
[0062] In this embodiment, such as Figure 3 As shown, setting the false-twist texturing machine to production status (step 102) may also include:
[0063] 303. Based on the third indication signal, increase the rotation speed of the false twister to the production speed.
[0064] In this embodiment, at step 301, for example, the main controller can also send a third indication signal to the second controller of the motor at the false twister to indicate that the false twisting machine has entered the production state, based on the acquired first indication signal; then at step 303, the second controller of the motor at the false twister increases the speed of the motor at the false twister according to the signal. This achieves the purpose of adjusting the speed of the motor at the false twister to the normal production speed.
[0065] In the embodiments of this application, such as Figure 1 As shown, prior to step 102, the control method may further include:
[0066] 104. Use the wire probe sensor in the false twisting texturer to determine whether the raw wire processing has been completed.
[0067] In this embodiment, a probe sensor installed before the winding device in the false twist texturer can be used to obtain a signal indicating whether the starting process has been completed; for example, when the probe sensor determines that the starting process has been completed, it sends a first indication signal to the main controller to indicate that the starting process has been completed. The probe sensor can determine that the starting process has been completed in a manner that is based on existing technology.
[0068] In the embodiments of this application, the method of determining whether the head growth process has been completed is not limited to using the indication signal sent by the probe sensor. For example, the completion of the head growth process can also be indicated by the operator's input operation. For example, after the operator completes the artificial head growth process, he / she presses the button indicating that the head growth process is completed, thereby sending a first indication signal to the main controller to indicate that the head growth process is completed.
[0069] In the embodiments of this application, such as Figure 1 As shown, prior to step 101, the control method may further include:
[0070] 105, Receive instruction information for instructing the false twisting machine to enter the head processing.
[0071] In this embodiment of the application, step 105 may include various indication methods, such as receiving an input operation command; receiving a start signal sent by a tension sensor in the false twist texturing machine; and receiving a yarn breakage signal fed back by the false twist texturing machine during the production process.
[0072] Specifically, before entering the production state after being powered on, the false twist texturer first enters the yarn-forming process state. At this time, the main controller can cause the false twist texturer to enter the yarn-forming process state based on the yarn-forming signal sent by the tension sensor (for example, the tension sensor can be a tension sensor for detecting yarn tension installed between the second conveyor and the false twister); or, based on the operation command input by the operator, the false twist texturer can enter the yarn-forming process state; or, if the false twist texturer receives a yarn breakage signal during the production process (for example, the yarn breakage signal can be sent to the main controller by the tension sensor installed between the second conveyor and the false twister, or it can be sent to the main controller by the yarn detection sensor), then it indicates that the yarn re-enters the yarn-forming process state, and then proceeds with the subsequent yarn-forming process.
[0073] In the embodiments of this application, the false twisting machine is not limited to being instructed to enter the starting process in the above three ways. For example, the false twisting machine can also enter the starting process state by the main controller receiving the power-on signal of the false twisting machine.
[0074] The above method will be illustrated below by taking a specific example of the process of a single yarn (fine denier porous yarn) advancing in a false twist texturer. In the example below, each spindle in the conveying device of the false twist texturer is equipped with a smart godet (i.e., a guide disc with a controller that individually controls its motor). The false twister through which the yarn passes is also equipped with a motor equipped with a second controller. Hereinafter, the guide discs at the first conveying device will be referred to as guide discs Gt1, the motors of guide discs Gt1 will be referred to as M1, and the controller (first controller) that individually controls motor M1 will be referred to as C1. The guide discs at the second conveying device will be referred to as guide discs Gt2, the motors of guide discs Gt2 will be referred to as M2, and the controller (first controller) that individually controls motor M2 will be referred to as C2. The motors at the false twister will be referred to as M6, and the controller (second controller) that individually controls motor M6 will be referred to as C6.
[0075] Figure 4 This is a flowchart of a control method for a false twisting texturing machine according to an embodiment of the first aspect of this application.
[0076] 401, Receive instruction information for instructing the false twisting machine to enter the head processing.
[0077] For example, the main controller of the false twist texturer can receive the instruction information through the operation command input by the operator; or, it can obtain the instruction information through the start-up signal sent by the tension sensor in the false twist texturer; or, it can trigger the false twist texturer to enter the start-up state by receiving a re-spinning signal that a yarn has broken during the production process.
[0078] 402, according to the instruction information, reduce the speed of the second conveying device and / or increase the speed of the first conveying device to adjust the draw ratio between the second conveying device and the first conveying device to a preset draw ratio; and reduce the speed of the motor at the false twister.
[0079] For example, the main controller of the false twist texturing machine can send an indication signal (second indication signal) to the controller C1 of the motor M1 of the guide disc Gt1 at the first conveying device to increase the rotational speed of the motor M1 of the guide disc Gt1 at the first conveying device; or it can send an indication signal (second indication signal) to the controller C2 of the motor M2 of the guide disc Gt2 at the second conveying device to decrease the rotational speed of the motor M2 of the guide disc Gt2 at the second conveying device; or it can send an indication signal (second indication signal) to the controller C1 of the motor M1 of the guide disc Gt1 at the first conveying device. The system sends an indication signal (second indication signal) to increase the rotational speed of the motor M1 of the guide disc Gt1 at the first conveying device, and also sends an indication signal (second indication signal) to the controller C2 of the motor M2 of the guide disc Gt2 at the second conveying device to decrease the rotational speed of the motor M2 of the guide disc Gt2 at the second conveying device; furthermore, the main controller of the false twisting machine can send a signal (fourth indication signal) to the controller C6 of the motor M6 at the false twister to decrease the rotational speed of the motor M6 at the false twister, so that the controller C6 decreases the rotational speed of the motor M6 at the false twister.
[0080] 403, Send a command signal to instruct the false twisting machine to enter the artificial head-forming process stage.
[0081] For example, after adjusting the draw ratio between the first and second conveying devices to a preset draw ratio, and after reducing the speed of motor M6 at the false twister to a preset speed, the main controller indicates, for example, through indicator lights, that the false twisting machine can enter the artificial head forming process stage.
[0082] 404, determine whether the head generation process is complete. If it is determined that the head generation process is complete, proceed to 405; if it is determined that the head generation process is not complete, then perform a loop check.
[0083] For example, the completion of the yarn-generating process is determined by whether a yarn has passed through the yarn-detecting sensor. Once the completion of the yarn-generating process is confirmed, a signal indicating completion (first indication signal) is sent to the main controller.
[0084] 405, Send a signal (third indication signal) to indicate that the false twist texturing machine has entered the production state.
[0085] For example, the main controller of the false twist texturing machine can send an instruction signal (third instruction signal) to the controller C1 of the motor M1 of the guide roller Gt1 at the first conveying device to reduce the rotational speed of the motor M1 of the guide roller Gt1 at the first conveying device; or it can send an instruction signal (third instruction signal) to the controller C2 of the motor M2 of the guide roller Gt2 at the second conveying device to increase the rotational speed of the motor M2 of the guide roller Gt2 at the second conveying device; or it can send both an instruction signal (third instruction signal) to the controller C1 of the motor M1 of the guide roller Gt1 at the first conveying device to reduce the rotational speed of the motor M1 of the guide roller Gt1 at the first conveying device and an instruction signal (fourth instruction signal) to the controller C2 of the motor M2 of the guide roller Gt2 at the second conveying device to increase the rotational speed of the motor M6 of the guide roller Gt2 at the second conveying device; and the main controller of the false twist texturing machine can send a signal (third instruction signal) to the controller C6 of the motor M6 at the false twister to increase the rotational speed of the motor M6 at the false twister.
[0086] 406. According to the third indication signal, increase the speed of the guide disc Gt2 motor at the second conveying device and / or decrease the speed of the guide disc Gt1 motor at the first conveying device to adjust the draw ratio between the second conveying device and the first conveying device to the production state draw ratio; and increase the speed of the motor at the false twister.
[0087] For example, the controller C1 of the motor M1 of the guide roller Gt1 at the first conveying device reduces the speed of the first conveying device according to the third indication signal; or the controller C2 of the motor M2 of the guide roller Gt2 at the second conveying device increases the speed of the second conveying device according to the third indication signal; or the controller C1 of the motor M1 of the guide roller Gt1 at the first conveying device reduces the speed of the first conveying device according to the third indication signal, and the controller C2 of the motor M2 of the guide roller Gt2 at the second conveying device increases the speed of the second conveying device according to the third indication signal; and the controller C6 of the motor M6 at the false twister reduces the speed of the motor M6 at the false twister according to the third indication signal.
[0088] In the embodiments of this application, the above embodiments describe the case where the false twist texturing machine is equipped with only a first conveying device and a second conveying device. However, this application is not limited to this. For example, when there is a second auxiliary conveying device in the false twist texturing machine, when performing the head-raising process on the transmission point of the second auxiliary conveying device, the rotational speed at the second auxiliary conveying device can also be reduced, thereby improving the success rate of the head-raising process at the second auxiliary conveying device.
