Description

Technical Field

[0001] This invention relates to the field of enameled wire production technology, and in particular to a winding control method, system and storage medium. Background Technology

[0002] In recent years, the take-up machine part of the felt coating type enameling machine (hereinafter referred to as "felt machine") has gradually evolved from "manual reel changing" to "machine reel changing".

[0003] Manual reel changing requires the operator's movements to keep pace with the enameled wire's travel speed, sequentially performing actions such as wire capture, wire breakage, and reel changing. Successful reel changing heavily depends on the operator's skill, especially at higher travel speeds where the operator's speed cannot keep up, easily leading to failed reel changes. For travel speeds exceeding 220 m / min, operators capable of successfully changing reels are extremely rare.

[0004] Machine reel changing involves the machine performing actions such as catching the line, breaking the line, and changing the reel. Machine reel changing is further subdivided into "automatic reel changing" and "manual reel changing." Automatic reel changing requires setting an accurate target length. When the taken-up length reaches the target length, the reel changing program starts, and the take-up machine performs the actions of catching the line, breaking the line, and changing the reel in one smooth motion. Manual reel changing requires the operator to visually estimate that the reel is nearly full, then click the "manual reel changing" button, and the take-up machine then performs the actions of catching the line, breaking the line, and changing the reel in sequence.

[0005] However, the existing method of setting a target length has obvious drawbacks. If the target length is not set accurately, it can lead to premature reel changing resulting in insufficient weight, or delayed reel changing resulting in excessive weight. Because enameled wire specifications and reel models vary, the target length when the reel is nearly full differs for different specifications and models. In some cases, to avoid excessive weight due to inaccurate target length settings, people choose to set a very large target length, thus avoiding automatic reel changing. When the reel appears nearly full, they then click the "manual reel change" button, essentially abandoning "automatic reel changing" and reluctantly opting for "manual reel change." Summary of the Invention

[0006] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide a take-up control method, system and storage medium, which solves the problems of high operator skill requirements for manual reel changing of enameled wire and inaccurate reel changing program start-up by setting target length in machine reel changing.

[0007] The technical solution adopted by this invention to solve its technical problem is: a wire take-up control method, comprising:

[0009] Obtain target line information and determine target conductor weight correction factor and enamel film weight correction factor;

[0010] The total weight of the target line body is calculated in real time using a formula.

[0011] When the total weight of the target line body is detected to have reached the set target weight, the reel changing procedure is initiated.

[0019] The take-up speed is obtained by multiplying the take-up reel speed by the take-up speed correction factor.

[0020] Get the timing, and multiply the take-up speed by the timing to get the take-up length L.

[0021] As a further improvement to the present invention, it also includes:

[0022] After determining the target conductor weight correction factor and the varnish weight correction factor, the target length is calculated.

[0023] When the wire length L is detected to have reached the target length, the reel-changing procedure is initiated.

[0024] As a further improvement of the present invention, the determination of the target length specifically includes:

[0025] Calculate the unit weight of the target wire and the unit weight of the enameled wire;

[0026] The corrected weight of the target wire is obtained by multiplying the unit weight of the target wire by the target conductor weight correction factor and the unit weight of the enameled wire by the enameled wire weight correction factor.

[0027] The target length is determined by the ratio of the target weight to the target line correction weight.

[0028] As a further improvement of the present invention, the take-up reel information includes the model number, and the target weight is determined based on the model number of the take-up reel.

[0029] As a further improvement of the present invention, the traction wheel shared by multiple machine heads is identified as the take-up wheel, and a speed measuring probe is installed on the traction wheel to measure the speed of the take-up wheel.

[0030] As a further improvement of the present invention, the linear speed of the guide wheel of the machine head is determined to be the speed of the take-up wheel.

[0031] This invention provides a take-up control system, comprising:

[0035] The processing module is used to start the reel-changing program when it detects that the total weight of the target line has reached the set target weight, or when it detects that the take-up length of the target line has reached the target length of the set target weight.

[0036] As a further improvement to the present invention, it also includes:

[0037] The third acquisition module is used to acquire the take-up length L of the target line in real time.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0050] In order to solve the technical problems in the prior art, the present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0051] like Figures 1 to 3As shown in the figure, this embodiment of the invention discloses a wire take-up control method, including the following steps:

[0052] S10: Obtain information about the take-up reel and determine the target weight;

[0053] The take-up reel information includes the model and target weight. The target weight can be basically determined by the reel model, as each model is associated with a unique target weight. Alternatively, the target weight can be determined based on a custom target weight setting for the reel. Different reels have different target weight setting fluctuation values. The target weight is determined by combining the original target weight with the fluctuation value.

[0054] In practical applications, felt making machines use PT-25, PT-15, and PT-10 reels, with corresponding full-load weights of 25kg, 15kg, and 10kg respectively. Once a specific reel model is selected, only the corresponding value needs to be set. For example, if a PT-25 reel is selected, the target weight can be set to 25kg.

[0055] This embodiment allows for intuitive weight setting. If the spool capacity permits, the setting value can be increased. For example, if a PT-25 spool is selected, the target weight can be set to 25-27 kg.

[0056] Information about the take-up reel can be obtained through image recognition, manual input, or other methods. When changing to different models of take-up reels, the target weight setting needs to be adjusted accordingly.

[0057] S20: Obtain target line information and determine target conductor weight correction factor and enamel film weight correction factor;

[0058] The target wire information includes the target wire specifications, target conductor density, target conductor diameter, enamel film density, and enamel film diameter. The system pre-sets target conductor weight correction factors and enamel film weight correction factors for different wire specifications.

[0059] This embodiment uses a target conductor weight correction factor to compensate for the weight of the target wire when it is not covered with enamel film, and also uses an enamel film weight correction factor to compensate for the weight of the enamel film, making the real-time weighing of the enameled wire more accurate.

[0060] S31: Use the formula to calculate the total weight of the target line body in real time;

[0061] In step S31 of this embodiment, the total weight of the target line body is calculated using the weighing formula M = ρ 导体 ×0.25×π×d 2 ×L×α+ρ 漆膜 ×0.25×π×(D 2 -d2 The specific meanings of the symbols in the formula are as follows: )×L×β

[0062] M represents the weight of the enameled wire, i.e., the total weight of the target wire body, in kg (kilograms).

[0063] ρ 导体 For the target conductor density, in the example, the copper conductor is taken as 8.9 g / cm3;

[0064] ρ 漆膜 For example, the density of the paint film is 1.4 g / cm³.

[0065] d is the diameter of the target conductor, in mm (millimeters);

[0066] D is the diameter of the enameled wire, i.e., the diameter of the target wire body, in mm (millimeters);

[0067] L represents the length of the enameled wire, i.e., the target wire length, in meters (m).

[0068] α is the target conductor weight correction factor, which has no unit and can be manually assigned a value of 0.000 to 2.000, with a default value of 1.000; β is the coating weight correction factor, which has no unit and can be manually assigned a value of 0.000 to 2.000, with a default value of 1.000; π is set to 3.1415926.

[0069] In practical applications, parameters such as conductor size, outer diameter of enameled wire, density of target conductor, and diameter of enamel film are given on the programmable logic controller (PLC) via a touch screen HMI.

[0070] On the programmable logic controller (PLC), design an online weighing formula to calculate the sum of the weight of the copper conductor and the weight of the enamel film from the start of winding up a coil of wire to the present.

[0071] When switching from producing enameled copper wire to enameled aluminum wire, online accurate weighing can be achieved by modifying the correction factor α without altering the basic PLC formula. Similarly, when switching between products with higher and lower coating densities, online accurate weighing can also be achieved by modifying the correction factor β without modifying the basic PLC formula.

[0072] Specifically, in this embodiment, both the target conductor weight correction factor and the varnish film weight correction factor are used to compensate for the calculated total weight of the target line.

[0073] Of course, in step S31 of this embodiment, the specific adjustments can be made according to different specifications of enameled wire. Either the target conductor weight correction factor or the enamel film weight correction factor can be used to compensate for the calculated total weight of the target wire. When only the target conductor weight correction factor is used to adjust the weighing formula, the enamel film weight correction factor is 0. Similarly, when only the enamel film weight correction factor is used to adjust the formula, the target conductor weight correction factor is 0.

[0074] This embodiment employs a multi-parameter correction weighing formula, making real-time weighing of enameled wire more accurate. Specifically, the weighing formula is based on parameters such as the conductor diameter d, the outer diameter D, and the winding length L, and adds the target conductor weight correction coefficient α and the enamel film weight correction coefficient β obtained in step S20 to perform multi-dimensional error correction, making real-time weighing of enameled wire more accurate.

[0075] The take-up speed is based on the speed of the traction wheel. Adding the target conductor weight correction factor and the varnish weight correction factor can, to some extent, be regarded as compensation for the error of the traction wheel speed.

[0076] Furthermore, the formula for calculating the length of enameled wire on the programmable logic controller (PLC) is L = v × T. The length of the wire taken up is L, which is the speed at which the wire is taken up from the start of winding up a coil until the current time.

[0077] In some implementations, such as Figure 4 As shown, the calculation of the take-up length L in step S31 specifically includes:

[0078] S311: Get the speed of the take-up reel;

[0079] In step S31, the speed of the take-up reel can be the speed of the traction reel or the linear speed of the guide wheels of each machine head. A speed measuring probe can be installed on the traction reel of the enameling machine to measure the speed of the traction reel. The method and device for obtaining the speed are existing technologies and will not be described in detail here.

[0080] Next, the speed of the traction wheel or the linear speed of the guide wheel is converted from an analog quantity to a digital quantity for subsequent digital calculations.

[0081] S312: Obtain the take-up speed correction coefficient, which is derived from a value preset by the system.

[0082] S313: The take-up speed is obtained by multiplying the take-up reel speed by the take-up speed correction factor;

[0083] The take-up speed is only a numerical value used to calculate the "take-up length in meters". In other words, correcting the take-up speed does not affect the actual rotation speed of the take-up reel.

[0084] The take-up speed is generally obtained by multiplying the measured linear speed of the traction wheel of the enameling machine by a correction factor. The enameling machine is a multi-head production line with slight differences in speed between the heads. The 12 heads on one side share a single traction wheel, and the enameled wire also slides relative to each other on the traction wheel.

[0085] Furthermore, it is possible to measure the linear velocity of the guide wheel used by each tractor head upstream of the traction wheel and multiply it by a correction factor to obtain the take-up speed. In this way, the take-up speed measured by each tractor head is more accurate than the actual speed, and thus the real-time take-up length of each tractor head calculated by increasing the take-up speed correction factor is more accurate.

[0086] S314: Get the timer, which is derived from the timer. The time elapsed from the start of the current time when the first coil was closed;

[0087] S315: The take-up length L is obtained by multiplying the take-up speed by the timing, also known as the take-up meter length.

[0088] The speed of the traction wheel is constant, which determines that the winding speed is also constant. Therefore, the real-time winding length L can be obtained by multiplying the winding speed by the timing.

[0089] In this embodiment, a winding speed correction coefficient is used to correct the displayed winding speed value based on the speed of the traction wheel of the felt machine, thereby improving the accuracy of the winding length measurement.

[0090] Furthermore, the take-up speed correction factor is manually assigned a value of 0.000 to 2.000, with no unit.

[0091] Generally, by setting a correction factor for the take-up speed, the take-up speed is kept consistent with the speed of the traction wheel, or the take-up speed is 1% faster than the speed of the traction wheel, i.e., the negative difference method. When the take-up speed is 1% faster than the speed of the traction wheel, the time to reach the target weight in real time is 1% earlier, and the actual weight is about 1% less than the target weight. After the weight is removed from the rack, the actual weight is about 99% of the target weight.

[0092] Compared to existing machines that use a set target length for reel changing, the target length varies for different specifications and different reel models when the reel is nearly full. To avoid setting the target length too high to prevent overweight, the online precise weighing method in this embodiment can be applied to reel changing operations for different specifications of enameled wire and different reel models. It introduces at least one of the following: take-up speed correction coefficient, target conductor weight correction coefficient α, and enamel film weight correction coefficient β, which effectively avoids overweight and accurately starts the reel changing procedure.

[0093] In some implementations, after performing steps S10 and S20, step S31 is not performed; instead, step S32 is performed to determine the corresponding target length based on the set target weight.

[0094] Step S32 specifically includes: calculating the target length by calling the formula based on the target line information, target conductor weight correction coefficient and varnish weight correction coefficient from step S20.

[0095] Furthermore, such as Figure 5 As shown, determining the target length L0 includes:

[0096] S321: Calculate the unit weight of the target line body, i.e., M1 = ρ 导体 ×0.25×π×d 2 ;

[0097] S322: Calculate the unit weight of enameled wire, i.e., M2 = ρ 导体 ×0.25×π×d 2 ;

[0098] S323: Calculate the corrected weight of the target wire by multiplying the unit weight of the target wire by the target conductor weight correction factor and the unit weight of the enameled wire by multiplying the enameled wire weight correction factor.

[0099] S324: Determine the target length as the ratio of the set target weight to the target line body correction weight.

[0100] Specifically, the formula for calculating the target length L0 is:

[0101] L0=M0 / (ρ 导体 ×0.25×π×d 2 ×α+ρ 漆膜 ×0.25×π×(D 2 -d 2 )

[0102] ×β), where M0 is the set target weight.

[0103] S41: When the real-time weight of the target line body is detected to have reached the set target weight, the reel changing procedure is started.

[0104] S42: When the real-time take-up length of the target line is detected to reach the target length of the set target weight, the reel-changing program is started.

[0105] This embodiment employs a target weight setting method, which initiates the reel-changing procedure once the real-time take-up length reaches the target length corresponding to the set target weight, or once the real-time target total weight of the line reaches the set target weight. After the reel-changing procedure is initiated, the take-up machine sequentially performs actions such as line capture, line breakage, and reel changing in one continuous process.

[0106] On the programmable logic controller (PLC), design an online weighing formula to calculate the sum of the weight of the copper conductor and the weight of the enamel conductor from the start of winding up a coil of wire to the present.

[0107] The target weight M0 is input to the PLC (Programmable Logic Controller) via HMI (Hybrid Mobile Interface). When the online weighing M ≥ the target weight M0, the PLC outputs a signal, the relay is energized, the take-up reel is automatically switched, the take-up of this reel ends, and the take-up of the next reel begins, thus achieving weight control.

[0108] Alternatively, the target weight M0 can be set on the PLC (Programmable Logic Controller) via HMI (Handheld Interface). The PLC calculates the target length L0 using a formula. When the real-time take-up length L ≥ the target weight L0, the PLC outputs a signal, the relay is energized, the take-up reel is automatically switched, the take-up of this reel ends, and the take-up of the next reel begins, thus achieving weight control.

[0109] like Figure 4 As shown, the total weight of the target line body calculated in step S31 specifically includes:

[0110] S316: After step S35, calculate the weight of the target conductor with a take-up length of L;

[0111] The target conductor weight in step S36 is calculated after compensation using a target conductor weight correction factor. The specific weighing formula is: M1 = ρ 导体 ×0.25×π×d 2 ×α×L;

[0112] S317: Calculate the weight of the paint film with a take-up length of L;

[0113] The paint film weight in step S37 is calculated after compensation using a paint film weight correction factor. The specific weighing formula is: M2 = 0.25 × π × (D 2 -d 2 )×β×L;

[0114] S318: The total weight of the target wire body with a take-up length of L is the sum of the weight of the enamel film with a take-up length of L and the weight of the target conductor with a take-up length of L.

[0115] When executing the weighing formula, an example is as follows: Figure 2 The diagram shows unit conversions and the main calculation process. The remaining calculations are based on the formulas. The specific meanings of the markings in the diagram are as follows:

Then: A = 0.0001165.

[0131] The difference between the square of the outer diameter of the enameled wire and the square of the diameter of the copper conductor is obtained.

[0132] Based on the same inventive concept, embodiments of the present invention also provide a take-up control system, comprising:

[0133] The first acquisition module is used to acquire information about the take-up reel and determine the target weight.

[0134] The second acquisition module is used to acquire target line information and determine the target conductor weight correction factor and enamel film weight correction factor.

[0135] The calculation module is used to call formulas to calculate the total weight of the target line body in real time;

[0136] The processing module is used to start the reel-changing program when the total weight of the target line body reaches the set target weight.

[0137] In an alternative implementation, the processing module is also configured to initiate a reel-changing procedure when it detects that the take-up length L has reached the target length.

[0138] Furthermore, the calculation module is also used to calculate the target length, specifically:

[0139] Calculate the unit weight of the target line body M1 = ρ 导体 ×0.25×π×d 2 ;

[0140] Calculate the unit weight of enameled wire M2 = ρ 导体 ×0.25×π×d 2 ;

[0141] The corrected weight of the target wire is obtained by multiplying the unit weight of the target wire by the target conductor weight correction factor and the unit weight of the enameled wire by the enameled wire weight correction factor.

[0142] The target length is determined by the ratio of the target weight to the target line correction weight.

[0143] In some implementations, it also includes:

[0144] The third acquisition module is used to acquire the take-up length L of the target line in real time.

[0145] The calculation module is also used to call the formula M = ρ 导体 ×0.25×π×d 2 ×L×α+ρ 漆膜 ×0.25×π×(D 2 -d 2 The total weight of the target line body is calculated by multiplying L by β.

[0146] Wherein, α is the target conductor weight correction factor, with a value range of 0.000 to 2.000; β is the coating weight correction factor, with a value range of 0.000 to 2.000.

[0147] In some implementations, the third acquisition module is also used to acquire the take-up reel speed, the take-up speed correction coefficient, and the timing; the calculation module is also used to calculate the take-up speed by multiplying the take-up reel speed by the take-up speed correction coefficient, and to calculate the take-up length L by multiplying the take-up speed by the timing.

[0148] Based on the same inventive concept, this embodiment of the invention also proposes a computer storage medium, the storage medium including a stored program, and a processor executing the program to implement the above-described wire take-up control method.

[0149] The main functions of this invention are:

[0150] 1. This invention adopts the target weight method and abandons the target length method, making the target setting value more intuitive and convenient.

[0151] 2. This invention employs a take-up speed correction coefficient, based on the speed of the felt machine's traction wheel, to correct the displayed take-up speed value, thereby improving the accuracy of the take-up length measurement. Generally, by setting the correction coefficient, the take-up speed is made to match the traction wheel speed, or the take-up speed is 1% faster than the traction wheel speed.

[0152] 3. This invention employs a multi-parameter correction weighing formula, making real-time weighing of enameled wire more accurate. The multi-parameter correction weighing formula is based on parameters such as the conductor diameter, outer diameter, and take-up length, and adds copper conductor weight correction coefficients and enamel film weight correction coefficients to perform multi-dimensional error correction, resulting in more accurate real-time weighing of the enameled wire. Since the take-up speed is based on the traction wheel speed, adding copper conductor weight correction coefficients and enamel film weight correction coefficients can, to some extent, be seen as compensation for traction wheel speed errors.

[0153] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions can be stored as one or more instructions or codes on or transmitted via a computer-readable medium.
