[0049] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0050] Example 1:

[0051] like Figure 1 As shown in the diagram, this embodiment of the invention provides a structural schematic of a water tank wire drawing and take-up machine. The take-up machine includes a tension component, a monofilament 5, a guide wheel 6, a take-up I-beam reel 7, a left reversing sensor 8, and a right reversing sensor 9. The tension component includes a tension swing rod 1, a counterweight 2, an eccentric circular sensing block 3, and a distance sensor 4. The monofilament 6 is wound around the take-up I-beam reel 7 via the tension swing rod 1 and the guide wheel 6. The outer diameter of the eccentric circular sensing block 3 changes according to the circumferential angle. Therefore, when the tension swing rod 1 swings, the distance detected by the distance sensor 4 changes, thereby converting the tension parameter. The tension swing rod 1 is adjusted by the counterweight 2 to maintain it in a target state, which is generally a horizontal state.

[0052] like Figure 2 and Figure 3 As shown, based on the above-mentioned take-up machine, this embodiment of the invention provides a method for drawing and laying steel cord wires, including:

[0053] Step S1: Obtain the tension parameters of the tension component.

[0054] The distance sensor acquires sensing data, which reflects the analog value of the position of the tension lever, and serves as the tension parameter.

[0055] Step S2: Using the moment when the cable guide wheel reverses direction as the time base point, extract the maximum and minimum values ​​of multiple tension parameters before and after the time base point.

[0056] Step S3: Calculate the parameter differences between the maximum and minimum values ​​and the tension threshold, respectively.

[0057] Step S4: Determine the fault based on the parameter difference, and control the line take-up based on the determination result.

[0058] Specifically, fault diagnosis based on parameter differences includes:

[0059] The reversing moment of the cable guide wheel is divided into the left reversing moment and the right reversing moment;

[0060] Let the parameter difference corresponding to the left commutation time be denoted as , For the first The parameter difference between the maximum and minimum values ​​corresponding to each left-side reversal moment and the tension threshold;

[0061] The parameter difference corresponding to the right-side commutation time is denoted as... , For the first The parameter difference between the maximum and minimum values ​​corresponding to each right-side reversal moment and the tension threshold;

[0062] If the parameter difference If the value is greater than or equal to the scrap threshold, it is determined that there is a severe bulge on the left half of the take-up reel; if the parameter difference is greater than or equal to the scrap threshold, it is determined that there is a severe bulge on the left half of the take-up reel. If the value is greater than or equal to the scrap threshold, it is determined that there is a severe dent on the left half of the take-up reel;

[0063] If the parameter difference If the value is greater than or equal to the rework threshold, it is determined that there is a slight bulge on the left half of the take-up reel; if the parameter difference is greater than or equal to the rework threshold, it is determined that there is a slight bulge on the left half of the take-up reel. If the value is greater than or equal to the rework threshold, it is determined that there is a slight dent on the left half of the take-up reel.

[0064] If the parameter difference If the value is greater than or equal to the scrap threshold, it is determined that there is a severe bulge on the right half of the take-up reel; if the parameter difference is greater than or equal to the scrap threshold, it is determined that there is a severe bulge on the right half of the take-up reel. If the value is greater than or equal to the scrap threshold, it is determined that there is a severe dent on the right half of the take-up reel;

[0065] If the parameter difference If the value is greater than or equal to the rework threshold, it is determined that there is a slight bulge on the right half of the take-up reel; if the parameter difference is greater than or equal to the rework threshold, it is determined that there is a slight bulge on the right half of the take-up reel. If the value is greater than or equal to the rework threshold, it is determined that there is a slight dent on the right half of the take-up reel.

[0066] Specifically, line control based on the judgment results includes:

[0067] Initialize the number of scrap checks at the left and right commutation times. ;

[0068] If the first If the judgment result corresponding to the left-side reversal moment is severe bulging or severe depression, then let ,otherwise, ;

[0069] If the first If the judgment result corresponding to the right-side reversal moment is severe bulging or severe depression, then let ,otherwise, ;

[0070] If the number of scrapping checks or If the number of scrap cycles reaches the threshold, the take-up machine will alarm and stop.

[0071] This take-up control system can predict when a finished reel will become unusable and issue an early warning to stop the machine. Only a few layers of monofilament on the take-up surface need to be processed, and the reel can still be used as a semi-finished product, eliminating waste and the need for scrap disposal processes.

[0072] Specifically, line control based on the judgment results includes:

[0073] Number of rework checks for initializing the left and right commutation times. ;

[0074] If the first If the discrimination result corresponding to the left-side reversal moment is a slight bulge or a slight depression, then let ,otherwise, ;

[0075] If the first If the judgment result corresponding to the right-side reversal moment is a slight bulge or a slight depression, then let ,otherwise, ;

[0076] If rework is required, the number of times should be checked. or If the rework threshold is reached, the take-up reel will require a second rework.

[0077] After determining that the take-up reel requires secondary rework, the next step is to determine the acceptable length of rework. ;

[0078] If the number of meters to be reworked The number of rework checks or When the rework threshold is reached, the take-up machine will alarm and stop.

[0079] If the number of meters to be reworked The number of rework checks or When the rework threshold is reached, obtain the number of meters of line taken up by the take-up reel at the current moment. ;

[0080] like If the winding machine alarms and stops, it will stop; otherwise, it will continue winding until the winding length reaches the specified value. When the winding machine alarms and stops, it will shut down. For the first The length of the rework section is the length of the finished twisted strand.

[0081] By using this take-up control, if it is predicted that a second rework is required, the specified number of meters of semi-finished products can be produced based on the meter values ​​set for multiple rework meter segments, thereby improving the efficiency of the semi-finished filaments in the subsequent twisting process and the yield of the twisted finished product.

[0082] During the production process, if the linear speed of the monofilament fluctuates (the monofilament has a low number of layers wrapped on the upstream traction wheel of the drawing machine, causing slippage), the tension swing arm will move up and down, and will be predicted to be scrapped or reworked, thus avoiding inefficient and energy-intensive production.

[0083] The method provided by the embodiments of the present invention can achieve significant results by upgrading the electrical control of existing winding machines at low cost, and various parameters can be changed and adapted according to the equipment status, production specifications and semi-finished product inventory.
