Description

Technical Field

[0001] The embodiments of the present application relate to the field of cable production, and in particular to a detection method and related equipment for a wire drawing machine cable arrangement mechanism. Background Art

[0002] In cable production, a wire drawing machine is a device that pulls a cable of one specification wire diameter into a smaller wire diameter specification. It is generally composed of three major mechanisms: multi-stage drawing, winding, and wire arrangement. The moving speed of the wire arrangement mechanism on the lead screw is determined by the speed of the winding shaft on the winding mechanism, so as to ensure that the cable is evenly arranged on the winding shaft. In addition, since the width of the winding shaft is limited, the wire arrangement must be able to change the moving direction on the lead screw when it reaches the boundary of the winding shaft, otherwise it will cause abnormal overlapping winding at the boundary or exceed the winding shaft, resulting in abnormal situations such as scrapping the wire. The existing wire arrangement mechanism relies on the left or right limit sensors installed at both ends to detect whether the wire arrangement has reached the boundary of the winding shaft for reversing, but there is no related abnormality detection function.

[0041] It should be noted that the descriptions involving "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] It should be noted in advance that in the existing technical solution, since the boundary detection only relies on limit sensors, if the limit sensor signal fails during production, if the alarm is not sounded in time to stop the machine and allow manual timer intervention, it will cause great property losses.

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] To solve the technical problems mentioned above, please refer to Figure 1 , Figure 1 The present invention is a flowchart of a method for detecting a wire arrangement mechanism of a wire drawing machine disclosed in an embodiment of the present application, including steps 101 to 103.

[0045] 101. Obtain the actual rotation speed value of the winding mechanism, and calculate the real-time linear speed value of the wire arrangement mechanism moving on the screw rod according to the actual rotation speed value.

[0046] It should be noted that this embodiment is mainly used in wire drawing machines. Among them, the wire drawing machine includes a multi-stage drawing mechanism, a winding mechanism and a wire arranging mechanism. Furthermore, it can also be considered that the lead screw (referring to the single-head lead screw also located in the wire drawing machine). Among them, the winding mechanism and the wire arranging mechanism are mainly used in this embodiment. The winding mechanism also includes a winding reel, a frequency converter, etc. The wire arranging mechanism also includes a frequency converter and a limit sensor.

[0047] Specifically, the wire drawing machine needs to obtain the actual rotation speed value of the winding mechanism, and then, based on the actual rotation speed value, the real-time linear speed value of the wire discharging mechanism moving on the screw rod can be calculated.

[0048] In one specific embodiment, the frequency converter of the wire arranging mechanism (i.e., the first frequency converter described above) can obtain the actual rotation speed value of the winding reel of the winding mechanism, and then, combined with the moving pitch when the winding reel rotates one circle, the linear speed of the wire arranging mechanism on the screw rod at this time can be obtained, that is, the real-time linear speed value.

[0049] 102. During the detection cycle, the current moving distance of the wire arrangement mechanism and the lead screw is calculated according to the real-time linear velocity value.

[0050] Furthermore, within the detection cycle, the current moving distance of the wire arrangement mechanism on the lead screw can be calculated according to the real-time linear velocity value obtained above.

[0051] In one specific embodiment, the distance moved by the cable arrangement mechanism may be calculated based on the linear velocity (real-time linear velocity value) of the cable arrangement mechanism during the current detection cycle, thereby obtaining the current moving distance.

[0052] Furthermore, its detection period is a fixed sampling period in the frequency converter (the specific time will be Figure 2 Detailed description), and its current moving position should not contact the limit sensor on the left or right side of the cable arrangement mechanism.

[0053] 103. If the current moving distance is greater than the preset width threshold, the wire drawing machine system is stopped.

[0054] Furthermore, when the current moving distance is greater than the preset width threshold, the wire drawing machine system can be stopped. It should be noted that the preset width threshold is associated with the width of the take-up reel of the take-up mechanism.

[0055] In one specific embodiment, after obtaining the moving length of the wire arrangement mechanism on the screw rod at this time, the ratio between the moving length of the wire arrangement mechanism on the screw rod and the set wire take-up reel width can be compared. Furthermore, when the current moving distance is greater than the wire take-up reel width (preset width threshold), the system can alarm and stop the wire drawing machine.

[0056] A detection method for the wire arranging mechanism of a wire drawing machine disclosed in this embodiment does not require the addition of additional sensors and mechanical costs. By setting a width threshold, the moving distance of the wire arranging mechanism is calculated, and then the abnormality of the wire arranging mechanism is detected, thereby effectively solving the problem of scrapping the wire when the winding mechanism is abnormal.

[0057] For further explanation Figure 1 For the detection method shown, see Figure 2 , Figure 2 This is a flow chart of another method for detecting a wire arrangement mechanism of a wire drawing machine disclosed in an embodiment of the present application, including steps 201 to 208.

[0058] 201. Determine the maximum operating frequency and the number of motor poles of the running motor of the winding mechanism, and determine the reduction ratio of the reduction box of the winding mechanism.

[0059] In this embodiment, steps 201 to 203 are the same as those described above. Figure 1 Specifically, it is necessary to first determine the maximum operating frequency and the number of motor poles of the running motor of the winding mechanism, and then determine the reduction ratio of the reduction box of the winding mechanism. It should be noted that the reduction box is used to drive the winding reel and the running motor of the winding mechanism, and the winding reel is used to drive the wire arrangement mechanism and the lead screw to move.

[0060] In one of the specific embodiments, the maximum speed of the winding reel needs to be calculated first. The maximum speed of the winding reel is determined by the maximum speed of the running motor of the winding mechanism and the reduction ratio of the reduction box. Therefore, it is necessary to determine the maximum operating frequency and the number of motor pole pairs of the running motor of the winding mechanism, as well as the reduction ratio value of the reduction box of the winding mechanism. It should be noted that the number of motor pole pairs is determined by the characteristics of the running motor. At the same time, the maximum frequency set by the frequency converter can also be set manually.

[0061] 202. According to the maximum operating frequency and the number of motor pole pairs, the maximum speed value of the operating motor of the winding mechanism is determined, and the maximum speed value of the winding reel is calculated according to the maximum speed value and the reduction ratio value.

[0062] Furthermore, the maximum speed value of the operating motor of the winding mechanism can be calculated according to the maximum operating frequency and the number of motor pole pairs, and the maximum speed value of the winding reel can be calculated according to the maximum speed value and the reduction ratio value.

[0063] In one of the specific embodiments, in the process of calculating the actual speed of the winding mechanism, the formula is known: motor speed = 60×F / P. Wherein, F is the operating frequency, and P is the number of motor pole pairs. Since the maximum frequency F_MAX set by the inverter of the winding mechanism (i.e., the second inverter mentioned above) is manually set according to the situation, the maximum speed of the winding mechanism motor is: 60×F_MAX / P. The maximum speed of the winding reel is determined by the maximum speed of the winding mechanism motor and the reduction ratio of the reduction box, so the maximum speed of the winding reel SJ_MaxRpm (in revolutions per minute) = the maximum speed of the winding mechanism motor / the reduction ratio of the reduction box.

[0064] 203. The output port signal simulated by the second frequency converter of the winding mechanism is collected through the input port simulated by the first frequency converter of the cable arrangement mechanism, and the actual speed value of the winding reel is calculated according to the output port signal and the maximum speed value.

[0065] Furthermore, the output port signal simulated by the second frequency converter of the winding mechanism can be collected through the input port simulated by the first frequency converter of the cable arrangement mechanism, and then the actual speed value of the winding reel can be calculated based on the output port signal and the maximum speed value.

[0066] In one specific embodiment, the first frequency converter of the cable arrangement mechanism can collect the output port signal simulated by the second frequency converter of the winding mechanism through the analog input port, wherein the simulated output port signal is: 0~10v corresponds to 0~SJ_MaxRpm. Therefore, the speed of the winding reel obtained by the cable arrangement mechanism is: SJ_Rpm=SJ_MaxRpm×AI / 10. Among them, AI in the formula represents the voltage value actually collected by the analog input port, and its voltage range is 0~10V. The second frequency converter of the winding mechanism quantifies the speed of 0~SJ_MaxRpm to 0~10v output through the analog output port. Then, the actual speed value of the winding reel at this time can be obtained.

[0067] 204. Set a preset pitch distance of the winding mechanism on the screw rod.

[0068] In this embodiment, steps 204 to 205 are the same as those described above. Figure 1 The step 102 in the embodiment is similar. Specifically, it is necessary to first set the preset pitch distance of the winding mechanism on the screw rod. It should be noted that the preset pitch distance is used to represent the pitch distance moved on the screw rod when the winding reel of the winding mechanism rotates one circle.

[0069] In one of the specific embodiments, since the winding shaft rotates one circle, the winding mechanism must move a set pitch on the lead screw, and then the set pitch is defined as a preset pitch distance PX_Step (unit: mm).

[0070] 205. Calculate the preset pitch distance and the actual rotation speed value to obtain the real-time linear speed value.

[0071] Then, the preset pitch distance and the actual rotation speed value can be calculated to obtain the real-time linear speed value of the wire arrangement mechanism on the screw rod.

[0072] In one specific embodiment, the preset pitch distance and the actual speed value obtained above are combined to obtain the formula: SG_LineSpeed ​​= SJ_Rpm x PX_Step / 60, wherein SG_LineSpeed ​​is the real-time line speed value (in mm / s) described above.

[0073] For example, if SJ_Rpm = 60 rpm (i.e. 1 revolution per second), PX_Step = 2 mm, then SG_LineSpeed ​​= 60×2 / 60 = 2 mm / s. It is not difficult to understand that the above is only an example of one of the specifically achievable linear speed values, but not a limitation on this value, and will not be described in detail later.

[0074] Furthermore, it is possible to select to execute step 208 or step 206 according to the real-time situation.

[0075] 206. If any detection cycle is reached, the real-time moving distance of the wire arrangement mechanism on the screw rod within the detection cycle is obtained according to the detection cycle and the real-time linear velocity value, and all real-time moving distances are accumulated in all detection cycles to obtain the current moving distance.

[0076] Furthermore, when any detection cycle is reached, the real-time moving distance of the wire arrangement mechanism on the screw rod during the detection cycle can be obtained based on the detection cycle and the real-time linear speed value, and all real-time moving distances are accumulated in all detection cycles to obtain the current moving distance.

[0077] In one of the specific embodiments, at any time, it is necessary to determine whether the limit sensor on the left or right side is triggered. Specifically, when the frequency converter of the cable arrangement mechanism does not detect that the limit sensor on the left or right side is touched, the length of the cable arrangement mechanism moving on the screw rod can be calculated according to the real-time linear speed value obtained in the above steps and the fixed sampling period T (in ms), that is, the real-time moving distance. Specifically, PX_DltLen=SG_LineSpeed×T. Among them, PX_DltLen is the real-time moving distance mentioned above, in units of 0.001mm. Then, it is executed once for each sampling period, that is, the cable movement length is accumulated, and PX_Length=PX_DltLen+PX_Length. Among them, the PX_Length is the current moving distance described above. For ease of understanding, the following examples are given. For example, if the sampling period is T = 4ms, SG_LineSpeed ​​= 2mm / s, then PX_DltLen = (4 / 1000s) × 2mm / s = 0.008mm. That is, PX_Length increases by 0.008mm every 4ms sampling period.

[0078] Furthermore, if the wiring mechanism has arrived within the sampling period (or the total calculation period), the execution ends.

[0079] 207. When the current moving distance is greater than the preset width threshold, an alarm is triggered and the wire drawing machine system operation is stopped.

[0080] Furthermore, based on step 206, when the current moving distance is greater than the preset width threshold, an alarm is processed and the operation of the wire drawing machine system is stopped.

[0081] In one of the specific embodiments, it is necessary to compare the movement length of the wire arrangement mechanism on the screw rod and set the width of the wire reel. Specifically, if PX_Length> the preset width threshold, an alarm can be issued to stop the wire drawing machine. Furthermore, the preset width threshold can be the sum of the wire reel width and the detection threshold. The detection threshold is freely set according to the site. Increasing this value will improve the anti-interference ability of fault detection and increase the delay of fault reporting.

[0082] For example: Example 1: The width of the take-up reel is 300mm, and the detection threshold is 0mm. Example 2: The width of the take-up reel is 300mm, and the detection threshold is 2mm. Example 3: The width of the take-up reel is 300mm, and the detection threshold is 5mm. That is, the width of the take-up reel is determined by the physical properties of the take-up reel, and the detection threshold can be set manually. The larger the setting, the less likely it is to report a fault.

[0083] 208. If at any time, the first frequency converter of the wire arrangement mechanism detects that the limit sensor of the wire drawing machine system is triggered, the current moving distance is cleared.

[0084] Corresponding to step 206, when the first frequency converter of the wire arrangement mechanism detects that the limit sensor of the wire drawing machine system is triggered at any time, the current moving distance can be cleared.

[0085] In one specific embodiment, when the inverter of the cable arrangement mechanism detects the left or right limit sensor at any time, the above PX_Length length is cleared and the process ends.

[0086] The detection method of the wire arranging mechanism of a wire drawing machine disclosed in this embodiment does not need to add additional sensors and mechanical costs, thereby solving the problem that when the left or right limit sensor fails, the wire arranging mechanism cannot be reversed and runs in one direction for a long time, thereby causing the wire to be scrapped due to abnormal wire winding on the wire winding reel, thereby improving the feasibility of the solution.

[0087] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
