Description

Technical Field

[0001] This application relates to, but is not limited to, the field of spinning production technology, and in particular to a control method, spinning production system, and equipment for a spinning production system. Background Technology

[0002] Melt spinning refers to the process where fiber-forming polymers are molten at a temperature 10 to 40 degrees Celsius above their melting point to form a relatively stable spinning melt. This melt is then extruded through a spinneret and shaped. The melt jet cools and solidifies in air or a liquid medium to form a semi-finished fiber. After further processing such as stretching and heat setting, it becomes the finished fiber. Among the main types of synthetic fibers, polyester, nylon, and polypropylene are all produced by melt spinning. Therefore, melt spinning is one of the most important methods in the spinning and forming of synthetic fibers.

[0003] In the melt spinning process, the processing steps such as melt jetting, cooling and solidification, stretching and heat setting need to ensure stable frequency. In existing melt spinning machines, it is difficult to keep the working frequency of the flow pump used for melt jetting and the roller used for stretching coordinated and stable, which makes it easy for the filament to break or entangle during the spinning process, resulting in poor filament quality and low production efficiency of existing melt spinning machines. Summary of the Invention

[0004] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0005] This application provides a control method, a spinning production system, and equipment for a spinning production system, which can improve the quality of spinning and the efficiency of spinning production.

[0006] To achieve the above objectives, this application proposes a control method for a spinning production system. The spinning production system includes a control module, an injection module, a stretching module, a winding module, and an alarm module. The injection module, the stretching module, the winding module, and the alarm module are electrically connected to the control module. The control method for the spinning production system includes: sequentially sending control signals carrying their respective target operating frequencies to the injection module, the stretching module, and the winding module to receive target feedback signals corresponding to each of the injection module, the stretching module, and the winding module; determining the operating state of the spinning production system based on each feedback signal; when the operating state is a fault state, controlling the alarm module to issue an alarm message; when the operating state is a normal state, controlling the injection module to inject spinning melt into the stretching module according to the corresponding target operating frequency, controlling the stretching module to stretch the spinning melt according to the corresponding target operating frequency to obtain a spun yarn, and controlling the winding module to wind the spun yarn according to the corresponding target operating frequency to obtain a spun yarn roll.

[0007] In some embodiments, the target operating frequency corresponding to the injection module is a first operating frequency, and the target feedback signal corresponding to the injection module is a first feedback signal. The step of sequentially sending control signals carrying their respective target operating frequencies to the injection module, the stretching module, and the winding module to receive the target feedback signals corresponding to each of the injection module, the stretching module, and the winding module includes: the control module sending a control signal carrying the first operating frequency to the injection module to adjust the operating state of the injection module; receiving the first feedback signal from the injection module; determining a first adjustment operating frequency based on the first feedback signal; and sending a control signal carrying the first adjustment operating frequency to the injection module until the operating state of the injection module meets a preset first target state.

[0009] In some embodiments, the spinning production system further includes a first timer electrically connected to the control module, the target operating frequency corresponding to the stretching module being a second operating frequency, and the target feedback signal corresponding to the stretching module being a second feedback signal. The step of sequentially sending control signals carrying their respective target operating frequencies to the jetting module, the stretching module, and the winding module to receive the target feedback signals corresponding to each of the jetting module, the stretching module, and the winding module includes: the control module sending a control signal carrying the second operating frequency to the stretching module to adjust its operating state; receiving the second feedback signal from the stretching module and determining its operating state based on the second feedback signal; and when the operating state of the stretching module is abnormal, controlling the alarm module to sound an alarm and controlling the first timer to start timing until the operating state of the stretching module is normal.

[0010] In some embodiments, the target operating frequency corresponding to the winding module is a third operating frequency, and the target feedback signal corresponding to the winding module is a third feedback signal. The step of sequentially sending control signals carrying their respective target operating frequencies to the jetting module, the stretching module, and the winding module to receive their respective target feedback signals includes: the control module sending a control signal carrying the third operating frequency to the winding module to adjust its operating state; receiving the third feedback signal from the winding module and determining its operating state based on the third feedback signal; determining the actual amount of raw material in the spinning roll based on the operating state of the winding module; and controlling the alarm module to sound an alarm when the actual amount of raw material is less than a preset full roll amount.

[0011] In some embodiments, the spinning production system further includes a second timer electrically connected to the control module. The operating state of the winding module includes a winding frequency. The determination of the actual raw material quantity of the spinning roll based on the operating state of the winding module, and controlling the alarm module to sound an alarm when the actual raw material quantity is less than a preset full roll quantity, includes: determining a first winding moment of the winding module using the second timer when the winding frequency begins to decrease; determining a second winding moment of the winding module using the second timer when the winding frequency stops decreasing; determining the actual raw material quantity of the spinning roll based on the first winding moment and the second winding moment; and controlling the alarm module to sound an alarm when the actual raw material quantity is less than the preset full roll quantity.

[0013] To achieve the above objectives, a second aspect of this application proposes a spinning production system, comprising a jetting module, a stretching module, a winding module, an alarm module, and a control module. The jetting module, the stretching module, the alarm module, and the winding module are electrically connected to the control module. The jetting module is used to jet spinning melt onto the stretching module. The stretching module is used to stretch the spinning melt to obtain a spun yarn. The winding module is used to wind the spun yarn to obtain a spun yarn roll. The control module is used to execute the control method described in the first aspect.

[0016] The embodiments of this application include at least the following beneficial effects: Before spinning in the spinning production system, the control module sequentially sends control signals for their respective target operating frequencies to the jetting module, stretching module, and winding module. Based on their respective target operating frequencies, the jetting module, stretching module, and winding module adjust their working states. The control module receives the target feedback signals after adjustment from the jetting module, stretching module, and winding module. Based on each target feedback signal, it compares it with the corresponding target operating frequency, enabling the control module to identify whether there is a communication anomaly in the jetting module, stretching module, or winding module. During the spinning process in the spinning production system, the control module can acquire and control the working state of the jetting module, thereby controlling the volume of the spinning melt jetted by the jetting module per unit time, thus controlling the fineness of the spun yarn. The control module acquires and controls the working state of the stretching module, enabling it to control the stretching frequency and stretching strength of the spinning melt, thereby adjusting the physical structure of the spun yarn and improving its strength and elasticity. By acquiring and controlling the working status of the winding module and adjusting its winding speed to match the jetting speed of the jetting module and the stretching frequency of the stretching module, the system can effectively reduce yarn breakage and improve the stability of the spinning production system. During spinning, when the target feedback information from the jetting, stretching, and winding modules indicates a fault in the spinning system, the alarm module will sound an alarm, promptly notifying staff to adjust and repair the system. This prevents yarn breakage caused by incoordination among the three modules and reduces the cost of continuing to jet the spinning melt after a breakage. Furthermore, by analyzing the target feedback information from the jetting, stretching, or winding modules, the system can easily determine the location and cause of the fault, enabling timely troubleshooting and repair, thus improving the maintenance efficiency of the spinning production system.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] In the description of this application, "several" means one or more, "multiple" means two or more, "greater than", "less than", "exceeding" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself.

[0030] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] To facilitate understanding of the technical solutions provided in the embodiments of this application, some key terms used in the embodiments of this application will be explained below:

[0032] Melt spinning is a highly efficient and continuous chemical fiber production technology. It involves heating and melting polymer raw materials into a melt of a certain viscosity, then using a spinning pump to uniformly deliver the melt to a spinneret. The melt is extruded through fine holes in the spinneret to form a fine filament stream. These filament streams are rapidly cooled and solidified in air to form nascent fibers with a certain strength and elasticity. Subsequently, through subsequent processes such as stretching, cooling, oiling, and winding, chemical fibers with specific properties are finally produced. This method is suitable for a variety of polymers that can melt without decomposing, such as polyester, polypropylene, and nylon, and has the advantages of high production efficiency, short process flow, and simple equipment.

[0033] In the melt spinning process, the processing steps such as melt jetting, cooling and solidification, stretching and heat setting need to ensure stable frequency. In existing melt spinning machines, it is difficult to keep the working frequency of the flow pump used for melt jetting and the roller used for stretching coordinated and stable, which makes it easy for the filament to break or entangle during the spinning process, resulting in poor filament quality and low production efficiency of existing melt spinning machines.

[0034] Based on this, embodiments of this application provide a control method for a spinning production system, a spinning production system and equipment, which can improve the quality of spinning and the efficiency of spinning production.

[0035] The control method, spinning production system and equipment of the spinning production system provided in this application are specifically described through the following embodiments. First, the control method of the spinning production system in the embodiments of this application is described.

[0036] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, Figure 1 This is an optional flowchart illustrating a control method for a spinning production system provided in an embodiment of this application. The control method can be executed by a server, a terminal, or a combination of both. The control method includes, but is not limited to, the following steps S110 to S140:

[0038] Step S110: Control signals carrying their respective target operating frequencies are sent sequentially to the injection module, stretching module and winding module to receive the respective target feedback signals from the injection module, stretching module and winding module.

[0039] Step S120: Determine the operating status of the spinning production system based on the feedback signals from each target;

[0040] Step S130: When the operating status is a fault state, the control alarm module issues an alarm message;

[0041] Step S140: When the operating state is normal, the spraying module sprays the spinning melt to the stretching module according to the corresponding target operating frequency, the stretching module stretches the spinning melt according to the corresponding target operating frequency to obtain a spinning strip, and the winding module winds the spinning strip according to the corresponding target operating frequency to obtain a spinning roll.

[0042] Based on this, before spinning in the spinning production system, the control module sequentially sends control signals for their respective target operating frequencies to the jetting module, stretching module, and winding module. According to their respective target operating frequencies, the jetting, stretching, and winding modules adjust their operating states. The control module receives the target feedback signals from these modules after adjustment and compares them with their corresponding target operating frequencies. The control module can then identify whether there are any communication anomalies in the jetting, stretching, or winding modules. During the spinning process, the control module can acquire and control the operating state of the jetting module, thereby controlling the volume of the spinning melt jetted per unit time, thus controlling the fineness of the spun yarn. The control module can also acquire and control the operating state of the stretching module, controlling the stretching frequency and tensile strength of the spinning melt, thereby adjusting the physical structure of the spun yarn and improving its strength and elasticity. Finally, the control module can acquire and control the winding module's operating state. By adjusting the winding speed of the winding module to match the jetting speed of the jetting module and the stretching frequency of the stretching module, the overall working status of the spinning system can be improved, thus reducing yarn breakage and enhancing the stability of the spinning production system. During spinning, if the target feedback information from the jetting, stretching, and winding modules indicates a fault in the spinning system, the alarm module will sound an alarm, promptly notifying personnel to adjust and repair the system. This prevents yarn breakage caused by incoordination among the three modules and reduces the cost of continuing to jet the spinning melt after a breakage. Furthermore, by analyzing the target feedback information from the jetting, stretching, or winding modules, the location and cause of the fault can be easily determined, enabling timely troubleshooting and repair, thus improving the maintenance efficiency of the spinning production system.

[0043] Additionally, refer to Figure 2 In one embodiment, the target operating frequency corresponding to the injection module is a first operating frequency, and the target feedback signal corresponding to the injection module is a first feedback signal. Figure 1Step S110 in the illustrated embodiment includes, but is not limited to, the following steps:

[0044] Step S210: The control module sends a control signal carrying a first operating frequency to the injection module to adjust the working state of the injection module;

[0045] Step S220: Receive the first feedback signal from the injection module;

[0046] Step S230: Determine the first adjustment operating frequency based on the first feedback signal, and send the control signal carrying the first adjustment operating frequency to the injection module until the working state of the injection module meets the preset first target state.

[0047] Understandably, the jetting module is a crucial component in the spinning production system. It is used to jet the spinning melt into the stretching module. The working state of the jetting module determines the quality of the spinning melt. By adjusting the first operating frequency of the jetting module, the flow rate of the spinning melt jetted by the jetting module per unit time can be controlled, thereby controlling the fineness of the spun yarn.

[0048] In one specific embodiment, the injection module includes a first frequency converter and a melt flow pump. The melt flow pump is electrically connected to the first frequency converter, and the melt flow pump and the first frequency converter are respectively electrically connected to a control module. The first frequency converter is used to receive a first operating frequency and control the first actual frequency of the melt flow pump according to the first operating frequency.

[0049] Based on this, the control module sends a first operating frequency to the first frequency converter, which controls the first actual frequency of the melt flow pump according to the first operating frequency. Secondly, the control module also acquires the first feedback signal of the melt flow pump. Based on the first feedback signal, the control module can determine the first actual frequency of the melt flow pump and determine a first adjustment operating frequency to adjust the first actual frequency of the melt flow pump, thereby making the spinning quality more in line with expectations. Furthermore, the control module can also determine the first adjustment operating frequency according to the needs input by the operator, thereby enabling the spinning production system to produce more diversified spinning products.

[0050] Additionally, refer to Figure 3 In one embodiment, the first feedback signal includes the first feedback operating frequency, the first feedback operating current, and the first feedback operating voltage of the injection module. Figure 2 Step S230 in the illustrated embodiment includes, but is not limited to, the following steps:

[0051] Step S310: Obtain the target injection frequency, target injection current range, and target injection voltage range;

[0052] Step S320: When the first feedback operating frequency is not equal to the target injection frequency, the first adjustment operating frequency is determined according to the target injection frequency, and the control signal of the first adjustment operating frequency is sent to the injection module.

[0053] Step S330: When the first feedback operating current deviates from the target injection current range or the first feedback operating voltage deviates from the target injection voltage range, the control alarm module will issue an alarm.

[0054] In one specific embodiment, the spinning production system further includes a fifth frequency converter whose operating frequency can be accurately controlled. The control module and the melt flow pump are electrically connected to the fifth frequency converter. Figure 3 In step S310, the target injection voltage range and the target injection current range are determined by the following steps:

[0055] First, the control module sends the target injection frequency to the fifth frequency converter;

[0056] Then, the fifth frequency converter controls the melt flow pump to spray at the target spray frequency;

[0057] Then, the control module obtains the target injection current range and target injection voltage range of the melt flow pump under the operating state of the target injection frequency.

[0058] It is understandable that for a specific target injection frequency, the corresponding target injection current range and target injection voltage range are usually unknown. Therefore, by setting a fifth frequency converter to control the melt flow pump to inject at the target injection frequency, and by obtaining the first actual current and first actual voltage of the melt flow pump at this time through the control module, the target injection current range and target injection voltage range of the melt flow pump at the target injection frequency can be determined.

[0059] Additionally, refer to Figure 4 In one embodiment, the spinning production system further includes a first timer, which is electrically connected to the control module. The target operating frequency corresponding to the stretching module is a second operating frequency, and the target feedback signal corresponding to the stretching module is a second feedback signal. Figure 1 Step S110 includes, but is not limited to, the following steps:

[0060] In step S410, the control module sends a control signal carrying a second operating frequency to the stretching module to adjust the working state of the stretching module.

[0061] Step S420: Receive the second feedback signal from the stretching module and determine the working status of the stretching module based on the second feedback signal;

[0062] Step S430: When the working state of the stretching module is abnormal, the alarm module is controlled to sound an alarm and the first timer is controlled to start timing until the working state of the stretching module is normal.

[0063] Specifically, the stretching module includes a second frequency converter and a stretching roller. The second frequency converter is electrically connected to the control module and the stretching roller respectively. The stretching roller is also electrically connected to the control module. The control module controls the stretching roller to rotate at a second operating frequency through the second frequency converter.

[0064] In one specific implementation, the control module determines a second adjustment operating frequency based on a second feedback signal and sends the second adjustment operating frequency to the stretching module to adjust the working state of the stretching module.

[0065] Specifically, the control module controls the stretching speed of the stretching module through the second operating frequency, and the second feedback signal includes the actual stretching speed of the stretching roller, the second actual frequency, the second actual current, and the second actual voltage.

[0066] In one specific implementation, Figure 4 Step S420 in the process specifically includes:

[0067] First, the control module acquires the actual stretching speed of the stretching roller, the second actual frequency, the second actual current, and the second actual voltage.

[0068] Then, when the actual stretching speed deviates from the preset target stretching speed range, the second actual frequency deviates from the preset target stretching frequency range, the second actual current deviates from the preset target stretching current range, or the second actual voltage deviates from the preset target stretching voltage range, the stretching module is determined to be in an abnormal state.

[0069] Understandably, the stretching roller is used to stretch the spinning melt, making the structure of the spun yarn more compact and improving its strength and elasticity. During the normal operation of the spinning production system, while the jetting module sprays the spinning melt onto the stretching module, spun yarn of the same mass enters the winding module. The total mass of the spun yarn in the stretching module should remain stable. However, when yarn breakage occurs between the stretching module and the winding module, the yarn becomes entangled on the stretching module. As the weight of the stretching module gradually increases, the mass of the stretching roller also gradually increases. Under the premise of maintaining the second actual stretching speed, the second actual current and the second actual voltage gradually increase, which can easily damage the stretching module. Therefore, by acquiring the second actual stretching speed, second actual frequency, second actual current, and second actual voltage of the stretching roller through the control module, it is possible to determine whether the yarn on the stretching roller is entangled. An alarm module can then be activated to promptly notify the staff for maintenance.

[0070] In one specific implementation, Figure 4The illustrated embodiments also include:

[0071] First, the stretching operation current and stretching operation voltage are obtained. When the difference between the second actual current and the stretching operation current is greater than a preset stretching current threshold, or the difference between the second actual voltage and the stretching operation voltage is greater than a preset stretching voltage threshold, the first stretching moment is determined by the first timer.

[0072] Then, when the difference between the second actual current and the stretching operation current is less than a preset stretching current threshold, or the difference between the second actual voltage and the stretching operation voltage is less than a preset stretching voltage threshold, the second stretching moment is determined by the first timer.

[0073] Then, the stretching loss time is determined based on the first stretching time and the second stretching time, and the first loss of raw material is determined by the stretching loss time and the first operating frequency.

[0074] It should be noted that a spinneret is installed at the outlet of the melt flow pump. After the melt flow pump stops spraying the spinning melt and a period of time has passed, the cooled spinning melt remaining on the spinneret changes the shape and size of the spinneret. The spinneret needs to be replaced before restarting the melt flow pump.

[0075] After determining the first amount of raw material lost each time, the first amount of raw material lost is stored in the raw material loss table. The control module obtains the first loss cost of replacing the spinneret and calculates the second loss cost based on the first amount of raw material lost in the raw material loss table. By comparing the first loss cost and the second loss cost, it determines whether to shut down the melt flow pump to minimize cost loss.

[0076] Additionally, refer to Figure 5 In one embodiment, the target operating frequencies corresponding to the winding module are the third operating frequency and the fourth operating frequency, respectively, and the target feedback signals corresponding to the winding module are the third feedback signal and the fourth feedback signal, respectively. Figure 1 Step S110 includes, but is not limited to, the following steps:

[0077] In step S510, the control module sends a control signal carrying the third and fourth operating frequencies to the winding module to adjust the working state of the winding module.

[0078] Step S520: Receive the third feedback signal and the fourth feedback signal from the roll-up module, and determine the working state of the roll-up module based on the third feedback signal and the fourth feedback signal.

[0079] Step S530: Determine the actual amount of raw material in the spinning roll based on the working status of the winding module. When the actual amount of raw material is less than the preset amount of raw material in the full roll, control the alarm module to sound an alarm.

[0080] Specifically, the winding module includes a winding roller and a third frequency converter. The winding roller is used to wind the stretched spun yarn into a spun yarn roll. The target operating frequency of the winding module includes the third operating frequency of the winding roller. The control module controls the winding roller to rotate at the third operating frequency through the third frequency converter. Furthermore, the target feedback signal of the winding module includes the third feedback signal of the winding roller. The control module also determines the working state of the winding roller through the third feedback signal.

[0081] Furthermore, the winding module also includes a grooved roller and a fourth frequency converter. The grooved roller is used to control the routing, shaping, and hardness of the spun yarn on the winding roller. The target operating frequency corresponding to the winding module also includes the fourth operating frequency corresponding to the grooved roller. The control module controls the grooved roller to rotate at the fourth operating frequency through the fourth frequency converter. In addition, the target feedback signal corresponding to the winding module also includes the fourth feedback signal corresponding to the grooved roller. The control module also determines the working status of the grooved roller through the fourth feedback signal.

[0082] Understandably, the third feedback signal includes the third actual frequency of the winding roller, and the fourth feedback signal includes the fourth actual frequency speed of the grooved roller. By acquiring the fourth actual speed of the grooved roller and the third actual speed of the winding roller, the third adjustment operating frequency corresponding to the winding roller and the fourth adjustment operating frequency corresponding to the grooved roller are determined based on the third actual frequency and the fourth actual speed. Adjusting the winding roller through the third adjustment operating frequency and adjusting the grooved roller through the fourth adjustment operating frequency can ensure the coordination between the jetting module, the stretching module, and the winding module, reducing the risk of yarn breakage during spinning. At the same time, by controlling the forming process at both ends of the spinning roll through the grooved roller, the spinning roll is prevented from having protruding or collapsed shoulders, reducing the generation of fuzz. This makes the tension of the spinning roll more stable and less prone to yarn breakage during the unwinding process in subsequent processes, thus improving the quality of spinning.

[0083] Additionally, refer to Figure 6 In one embodiment, the spinning production system further includes a second timer, which is electrically connected to the control module. The operating state of the winding module includes the winding frequency. Figure 5 Step S530 includes, but is not limited to, the following steps:

[0084] Step S610: When the winding frequency begins to decrease, the first winding moment of the winding module is determined by the second timer;

[0085] Step S620: When the winding frequency stops decreasing, the second winding moment of the winding module is determined by the second timer;

[0086] Step S630: Determine the actual amount of raw material in the spinning roll based on the first and second roll-to-roll times. When the actual amount of raw material is less than the preset amount of raw material in the full roll, the alarm module will sound an alarm.

[0087] Understandably, the control module controls the winding rotation speed of the winding module by controlling the winding frequency.

[0088] Understandably, as the winding module winds the spun yarn, the diameter of the winding roller continuously increases. However, since the first actual frequency of the jetting module and the actual stretching speed of the stretching module remain stable, based on the mathematical relationship between angular velocity and linear velocity, it can be known that if the length of the spun yarn wound per unit time remains constant, i.e., the circumferential linear velocity of the winding roller remains constant, the angular velocity of the winding roller needs to continuously decrease. In other words, the third actual frequency of the winding roller needs to continuously decrease. That is, when the spun yarn begins to enter the winding module for winding, the winding frequency needs to continuously decrease, i.e., the actual winding angular velocity of the winding module needs to continuously decrease.

[0089] Therefore, by acquiring the winding frequency of the winding module, when the winding frequency begins to decrease, it indicates that the spinning strip has begun to be wound. When the winding frequency stops decreasing, it indicates that the spinning strip has been wound. The continuous winding time is calculated using the first and second winding times. The actual linear velocity of the spinning strip is rated using the actual jetting frequency of the jetting module. The actual amount of raw material is determined by the continuous winding time and the linear velocity of the spinning strip. Thus, the amount of raw material consumed by the spinning roll can be obtained. When the actual amount of raw material is less than the preset amount of raw material for the full roll, it indicates that there is an abnormal spinning loss problem in the spinning production system. The control alarm module will sound an alarm and notify the staff to inspect and repair the spinning production system. This can reduce spinning loss in a timely manner and improve the production efficiency of the spinning production system.

[0090] Additionally, refer to Figure 7 In one embodiment, Figure 6 The control method shown also includes, but is not limited to, the following steps:

[0091] Step S710: When the winding frequency begins to decrease, the third winding moment of the winding module is determined by the second timer;

[0092] Step S720: Determine the amount of raw material lost during winding by the second winding time and the third winding time.

[0093] Specifically, when the winding frequency stops decreasing, it indicates that the winding roller has stopped winding the spun yarn. At this time, the spinning production system may be undergoing maintenance or the spinning spool may be being disassembled on the winding roller. When the winding frequency starts decreasing again, the third winding time is determined. The winding loss time can be determined by the second and third winding times. The amount of winding loss material is determined by the winding loss time and the first operating frequency. After each determination of the winding loss material amount, the amount of winding loss material is also stored in the material loss table.

When the winding frequency stops decreasing, the melt flow pump is compared with the first and third loss costs to determine whether to shut down the melt flow pump to minimize cost loss.
