Description

Technical Field

[0001] The invention relates to the technical field of enameled wire production, and in particular to a wire take-up control method, system and storage medium. Background Art

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

[0003] Manual reel change requires the operator to keep up with the speed of the enameled wire, and to successively perform actions such as catching the wire, breaking the wire, and reel change. The success of reel change is highly dependent on the operator's personal skills, especially when the line speed is fast, the operator's operation speed cannot keep up, and the reel change operation is very likely to fail; for line speeds above 220m / min, operators who can successfully implement reel change are rare.

[0004] Machine reel change means that the machine performs actions such as catching the wire, breaking the wire, and changing the reel. Machine reel change is further divided into "automatic reel change" and "manual reel change". Automatic reel change requires setting an accurate target length. When the length of the wire collected reaches the target length, the reel change program starts, and the wire take-up machine successively performs actions such as catching the wire, breaking the wire, and changing the reel in one go. Manual reel change requires the operator to visually check that the wire is close to full, and then click the "manual reel change" button, and then the wire take-up machine successively performs actions such as catching the wire, breaking the wire, and changing the reel.

[0005] However, the existing method of setting the target length has obvious shortcomings. If the target length is not set accurately, it will cause the reel to be changed in advance and underweight, or the reel to be changed later and overweight. Due to the various specifications of enameled wires and the various types of take-up reels, the target lengths of different specifications and different take-up reels are different when they are close to full. In order to avoid overweight caused by inaccurate target length setting, the target length is set to a large value to avoid automatic reel change. When the reel is close to full, the "manual reel change" button is clicked. This means that the "automatic reel change" is abandoned and the "manual reel change" is selected. Summary of the invention

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

[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

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

[0051] like Figures 1 to 3As shown above, the embodiment of the present invention discloses a line taking-up control method, comprising the following steps:

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

[0053] The take-up reel information includes model and target weight. The target weight can be basically determined by the take-up reel model. Each model is associated with a unique target weight. The corresponding target weight can also be determined according to the custom target weight of the take-up reel. The target weights of different take-up reels have different set floating values. The target weight is determined based on the original target weight and the set floating value.

[0054] In actual applications, the types of felt machine take-up reels include PT-25, PT-15, PT-10, etc., and the full reel weights correspond to 25kg, 15kg, and 10kg respectively. After deciding to use a certain type of reel, you only need to set the value of the corresponding model. For example, if you decide to use the PT-25 reel, you only need to set the target weight to 25kg.

[0055] The weight is set intuitively in this embodiment, and if the capacity of the wire drum allows, the set value can be increased. For example, if the PT-25 wire drum is determined to be used, the target weight only needs to be set to 25-27 kg.

[0056] The information of the take-up reel can be obtained by image recognition, manual input, etc. If a take-up reel of a different model is replaced, the target weight needs to be adjusted accordingly.

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

[0058] The target wire body information includes the target wire body specification, the density of the target conductor, the diameter of the target conductor, the paint film density, and the paint film diameter. The system pre-sets the target conductor weight correction coefficient and the paint film weight correction coefficient corresponding to wire bodies of different specifications.

[0059] This embodiment uses the target conductor weight correction coefficient to compensate for the weight of the target wire body when it is not coated with a paint film, and also uses the paint film weight correction coefficient to compensate for the paint film weight, so that the real-time weight measurement of the enameled wire is more accurate.

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

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

[0062] M is the weight of the enameled wire, that is, the total weight of the target wire, in kg (kilogram);

[0063] ρ 导体 The target conductor density is 8.9 g / cm3 for copper conductor.

[0064] ρ 漆膜 is the paint film density, for example, 1.4g / cm3;

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

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

[0067] L is the length of the enameled wire, that is, the target wire length, in m (meter);

[0068] α is the target conductor weight correction coefficient, without unit, manually assigned value 0.000~2.000, default 1.000; β is the paint film weight correction coefficient, without unit, manually assigned value 0.000~2.000, default 1.000, π value is set to 3.1415926.

[0069] In actual applications, parameters such as conductor size, enameled wire outer diameter, target conductor density, and paint film diameter are given on the programmable controller PLC through the touch screen HMI.

[0070] On the programmable controller PLC, an online weighing formula is designed to calculate the sum of the copper conductor weight and paint film weight from the start of winding a reel of wire to the current state.

[0071] When the production of enameled copper wire is changed to enameled aluminum wire, accurate online weighing can be achieved by modifying the correction coefficient α without modifying the basic PLC formula. When switching between varieties with higher paint film density and those with lower paint film density, accurate online weighing can also be achieved by modifying the correction coefficient β without modifying the basic PLC formula.

[0072] Specifically, in this embodiment, the target conductor weight correction factor and the paint film weight correction factor are simultaneously used to compensate for the calculated target wire body total weight.

[0073] Of course, in step S31 of this embodiment, according to the specific adjustment of different specifications of enameled wires, only the target conductor weight correction coefficient or only the paint film weight correction coefficient can be used to compensate the calculated target wire total weight. When only the target conductor weight correction coefficient is used to adjust the weight formula, the paint film weight correction coefficient is 0. Similarly, when only the paint film weight correction coefficient is used to adjust the formula, the target conductor weight correction coefficient is 0.

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

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

[0076] Furthermore, a calculation formula for the length of the enameled wire is designed on the programmable controller PLC as L=v×T. The time from the start of winding a coil of wire to the current timing is multiplied by the winding speed, which is also the winding length L.

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

[0078] S311: Obtaining the speed of the take-up wheel;

[0079] The speed of the take-up wheel in step S31 can be the speed of the traction wheel, or the linear speed of the independent guide wheels of each head. A speed measuring probe can be installed on the traction wheel of the enameling machine to measure the speed of the traction wheel. The speed acquisition method and device are prior art and will not be described in detail here.

[0080] Then the traction wheel speed or guide wheel linear speed is converted from analog to digital for subsequent digital calculations.

[0081] S312: Obtaining a correction coefficient for the take-up speed, where the correction coefficient for the take-up speed is derived from a value preset by the system;

[0082] S313: multiplying the take-up wheel speed by the take-up speed correction coefficient to obtain the take-up speed;

[0083] The take-up speed is only a digital quantity used to calculate the "take-up length in meters", that is, the correction of the take-up speed does not affect the actual speed of the take-up reel;

[0084] Generally, the measured line speed of the enameling machine traction wheel is multiplied by the correction coefficient as the take-up speed. The enameling machine is a multi-head production, and the speeds between the heads are slightly different. The 12 heads on one half share a traction wheel. At the same time, the enameled wire also slides relatively on the traction wheel.

[0085] Furthermore, it is possible to consider measuring the linear speed of the guide wheel used by each head upstream of the traction wheel and multiplying it by the correction coefficient as the take-up speed. In this way, the take-up speed measured by each head is more accurate than the actual one, and then the real-time take-up length of each head calculated by adding the take-up speed correction coefficient is more accurate.

[0086] S314: Get timing, which comes from a timer Count the time from the beginning of the reel reeling to the current time;

[0087] S315: The take-up speed is multiplied by the time to obtain the take-up length L, also known as the take-up length in meters.

[0088] The traction wheel speed is uniform, which determines that the take-up speed is also uniform. Therefore, the real-time take-up length L is obtained by multiplying the take-up speed by the timing.

[0089] In this embodiment, a take-up speed correction coefficient is used to correct the take-up speed display value based on the traction wheel speed of the felt machine, thereby improving the accuracy of the take-up length in meters.

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

[0091] Generally, by setting the take-up speed correction coefficient, the take-up speed is kept consistent with the traction wheel speed, or the take-up speed is 1% faster than the traction wheel speed, that is, the negative difference method, the take-up speed is 1% faster than the traction wheel speed, the real-time weight reaches the target weight 1% earlier, the real weight is about 1% less than the target weight, and after the disc is unloaded, the real weight is about 99% of the target weight.

[0092] Compared with the existing machine reel changing which adopts the setting target length, the target lengths of different specifications and different take-up reel models are different when they are close to full. In order to avoid overweight, the target length is set too large. The online precise weighing method of this embodiment can be applied to the reel changing operations of enameled wires of different specifications and different take-up reel models, and at least one of the take-up speed correction coefficient, the target conductor weight correction coefficient α and the paint film weight correction coefficient β is introduced to effectively avoid overweight and accurately start the reel changing program.

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

[0094] Step S32 specifically includes: according to the target line body information, the target conductor weight correction coefficient and the paint film weight correction coefficient in step S20, a formula is called to calculate and obtain the target length.

[0095] Furthermore, if Figure 5 As shown, the determination of the target length L0 includes:

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

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

[0098] S323: Calculate the sum of the target wire unit weight multiplied by the target conductor weight correction coefficient and the enameled wire unit weight multiplied by the enameled wire weight correction coefficient to obtain the target wire body correction weight;

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

[0100] Specifically, the target length L0 is calculated as:

[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 it is detected that the real-time weight of the target line body reaches the set target weight, the disc changing program is started.

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

[0105] This embodiment adopts the method of setting the target weight, and can start the reel-changing program when the real-time wire length reaches the target length corresponding to the set target weight, or when the real-time target wire total weight reaches the set target weight. After the reel-changing program is started, the wire-taking machine successively performs the actions of catching the wire, pulling the wire, and changing the reel, all in one go.

[0106] On the programmable controller PLC, an online weighing formula is designed to calculate the sum of the copper conductor weight and the paint film conductor weight from the start of winding a reel of wire to the current time.

[0107] The target weight M0 is given on the PLC (programmable controller) through the HMI (touch screen). When the online weighing M≥the target weight M0, the PLC (programmable controller) outputs a signal, the relay is energized, the take-up reel is automatically changed, the current reel is taken up and the next reel starts to take up, thus achieving weight control.

[0108] The target weight M0 can also be given on the PLC (programmable controller) through the HMI (touch screen), and the PLC (programmable controller) calculates the target length L0 through the formula. When the real-time wire-reeling length L≥the target weight L0, the PLC (programmable controller) outputs a signal, the relay is energized, the wire-reeling reel is automatically changed, the wire-reeling of the current reel ends, and the wire-reeling of the next reel begins, thus realizing weight control.

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

[0110] S316: After step S35, the target conductor weight of the collected line length L is calculated;

[0111] The target conductor weight in step S36 is calculated after compensation using the target conductor weight correction coefficient. The specific weight calculation 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 by using the paint film weight correction coefficient for compensation. The specific weight calculation formula is: M2 = 0.25 × π × (D 2 -d 2 )×β×L;

[0114] S318: The target total wire weight of the collected wire length L is the sum of the paint film weight of the collected wire length L and the target conductor weight of the collected wire length L.

[0115] When executing the weight formula, the example Figure 2 As shown, it represents the unit conversion and the main calculation process. The rest of the calculation process is based on the formula. The specific meanings of the symbols in the attached figure are as follows:

[0116] Multiply by the square of the copper conductor diameter. The square of the copper conductor diameter comes from

[0117] Multiply by the copper weight correction factor. The copper weight correction factor is derived from

[0118] Multiply by the constant (A). The constant (A) is the constant obtained by multiplying the copper density by the unit conversion. If: the unit of copper conductor weight is kg, the unit of copper density is g / cm 3 , the unit of copper conductor diameter is mm, the unit of time is s, the unit of speed is m / min, then: A=0.0001165.

If: the unit of the paint film weight is kg, the unit of the paint film density is g / cm 3 , the unit of the outer diameter of the enameled wire and the diameter of the copper conductor is mm, the unit of time is s, the unit of speed is m / min, then: B=0.00001836.

[0131] Subtract the square of the copper conductor diameter from the square of the enameled wire outside diameter to get the difference between the two.

[0132] Based on the same inventive concept, an embodiment of the present invention further provides a line-receiving control system, comprising:

[0133] The first acquisition module is used to obtain the take-up reel information and determine the set target weight;

[0134] The second acquisition module is used to obtain target line body information and determine the target conductor weight correction coefficient and the paint film weight correction coefficient;

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

[0136] The processing module is used to start the disc changing program when it is detected that the total weight of the target line body reaches the set target weight.

[0137] In an alternative implementation, the processing module is further configured to start the reel changing procedure when it is detected that the line taking-up length L reaches a target length.

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

[0139] Calculate the target line unit weight 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 target wire body corrected weight is obtained by calculating the sum of the target wire body unit weight multiplied by the target conductor weight correction coefficient and the enameled wire unit weight multiplied by the enameled wire weight correction coefficient;

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

[0143] In some implementations, further comprising:

[0144] The third acquisition module is used to obtain the reel 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 )×L×β to calculate the total weight of the target line;

[0146] Among them, α is the target conductor weight correction factor, ranging from 0.000 to 2.000; β is the paint film weight correction factor, ranging from 0.000 to 2.000.

[0147] In some embodiments, the third acquisition module is also used to obtain the take-up wheel speed, the take-up speed correction coefficient and the timing; the calculation module is also used to calculate the take-up wheel speed multiplied by the take-up speed correction coefficient to obtain the take-up speed, and calculate the take-up speed multiplied by the timing to obtain the take-up length L.

[0148] Based on the same inventive concept, an embodiment of the present invention further proposes a computer storage medium, wherein the storage medium includes a stored program, and a processor executes the program to implement the above-mentioned line-reeling control method.

[0149] The main functions of the present invention are:

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

[0151] 2. The present invention adopts a take-up speed correction coefficient, based on the felt machine traction wheel speed, to correct the take-up speed display value, thereby improving the accuracy of the take-up meter length. In general, by setting the correction coefficient, the take-up speed is kept consistent with the traction wheel speed, or the take-up speed is 1% faster than the traction wheel speed.

[0152] 3. The present invention adopts a multi-parameter corrected weight formula to make the real-time weight of the enameled wire more accurate. The multi-parameter corrected weight formula is based on parameters such as the enameled wire conductor diameter, the enameled wire outer diameter, and the length of the wire taken up in meters. The copper conductor weight correction coefficient and the paint film weight correction coefficient are added to perform multi-dimensional error correction, making the real-time weight of the enameled wire more accurate. Since the take-up speed is based on the traction wheel speed, adding the copper conductor weight correction coefficient and the paint film weight correction coefficient can also be regarded as compensation for the traction wheel speed error to some extent.
