Description

Technical Field

[0001] The present application relates to the technical field of fineness detection, and in particular to a fineness detection system and method. Background Art

[0002] Fiber fineness is a parameter that characterizes the thickness of the fiber. Its deviation directly affects the difficulty of subsequent fiber processing and the use value of the fiber products. Therefore, it is necessary to test the fineness.

[0003] Since the existing high-performance polyethylene fiber production line only has the function of producing and winding fibers, the existing fineness detection requires that the fiber roll be manually removed for weighing after the fiber is wound up, and the fineness is calculated based on the manually recorded breakpoint information and the fiber length of the fiber roll. However, the manual recording of breakpoint information is prone to the risk of information recording errors in large-scale production, which affects the calculation accuracy of the fineness. In addition, since the existing manual fineness detection needs to be carried out after the fiber roll is manually removed for weighing, and the calculation cannot be completed on the production line, the fineness detection efficiency is reduced. Therefore, how to improve the fineness detection accuracy and detection efficiency has become an urgent problem to be solved. Summary of the invention

[0049] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0050] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application.

[0052] The first aspect of the present application provides a fineness detection system. The block diagram of the fineness detection system is as follows: Figure 1 As shown, the fineness detection system includes:

[0053] At least one length measuring device 101, at least one controller 102, a computer 103 and an electronic scale 104,

[0054] The length measuring device 101 is in communication connection with the controller 102, and the controller 102 and the electronic scale 104 are both in communication connection with the computer 103. The length measuring device 101 is deployed at the target fiber bundle outlet of the fiber production line, and the electronic scale 104 is deployed at the winding mechanism of the fiber production line;

[0055] The length measuring device 101 is used to collect the fiber length and fiber output rate of the fibers output from the target fiber bundle outlet; and send the fiber length and fiber output rate corresponding to the target fiber bundle outlet to the controller 102;

[0056] The controller 102 is used to receive the fiber length and the fiber output rate, and record the breakpoint information corresponding to the target fiber bundle outlet based on the fiber output rate and the fiber length; and send the fiber length and breakpoint information corresponding to the target fiber bundle outlet to the computer 103;

[0057] The computer 103 is used to send a weight measurement instruction to the electronic scale 104 when the fiber length reaches a preset length;

[0058] The electronic scale 104 is used to measure the weight of the fiber roll of the winding mechanism in response to the weight measurement instruction sent by the computer, and send the weight of the fiber roll to the computer 103;

[0059] The computer 103 is also used to calculate the fineness of the fibers output from the target fiber bundle outlet according to the fiber length, breakpoint information and the fiber roll weight sent by the electronic scale 104.

[0060] It should be noted that, in actual application scenarios, the length measuring device 101 may be of various types, including but not limited to: a photoelectric wire detection sensor, a photoelectric tachometer, a speed and length measuring sensor, and the like.

[0061] It should be noted that, in actual application scenarios, the controller 102 may be a programmable logic controller (PLC) configured with a breakpoint detection program. In actual application scenarios, a fiber production line may be configured with multiple fiber bundle outlets, and there may be multiple length measuring devices 101. In order to reduce costs, the controller 102 may be configured with multiple data transmission interfaces, so that each length measuring device 101 is connected to the controller 102 through different data transmission interfaces, thereby using one controller 102 to detect and record the breakpoint information of multiple fiber bundle outlets.

[0062] It should be noted that, in actual application scenarios, the computer 103 may be an electronic device configured with a corresponding program to realize the control of the electronic scale 104 and the fiber size calculation function. The computer 103 may also provide an object linking and embedding process control (OLE for Process Control, OPC) protocol interface to facilitate data calls by third parties (such as quality regulators, downstream fiber users, upstream quality control parties, etc.).

[0063] The present application configures a fiber fineness detection system including at least one length measuring device, a controller, a computer and an electronic scale, and uses the controller to record breakpoint information based on the fiber length and fiber output rate collected by the length measuring device, thereby avoiding the risk of information recording errors that may occur in the existing method of manually recording breakpoint information in large-scale production. Subsequently, by configuring the computer to calculate the fiber fineness output from the target fiber bundle outlet according to the fiber roll weight, fiber length and breakpoint information sent by the electronic scale, the present application can complete the fiber fineness calculation on the production line without removing the fiber roll from the production line, thereby improving the fiber fineness detection efficiency. It can be seen that the present application improves the fineness detection accuracy and detection efficiency.

[0064] In one possible implementation, the above Figure 1 The titer detection system shown also includes:

[0065] A two-dimensional code printing device, the two-dimensional code printing device is communicatively connected with the computer;

[0066] The two-dimensional code printing device is used to generate a finished fiber information two-dimensional code of the fiber roll based on at least the outlet identification, fiber length, fineness and fiber weight of the target fiber bundle outlet sent by the computer.

[0067] It should be noted that, in actual application scenarios, in order to prevent the fiber roll from being damaged during the offline and transportation process, a paper roll is usually sleeved on the winding shaft of the winding mechanism so that the fiber is wound around the wall of the paper roll, thereby preventing the handling equipment from contacting the fiber roll and causing damage to the fiber roll. However, this also causes the weight of the fiber roll obtained by the electronic scale 104 to include the weight of the paper roll, which in turn affects the accuracy of determining the fiber fineness. Therefore, before fiber production, it is necessary to measure the weight of the paper roll when it is not in use, so that the computer 103 removes the weight of the paper roll from the weight of the fiber roll when calculating the fineness, thereby improving the calculation accuracy of the fineness. Therefore, the above-mentioned two-dimensional code printing device can also be configured to communicate with the electronic scale 104, and generate a two-dimensional code including the weight of the paper roll based on the weight of the paper roll sent by the electronic scale 104. The production staff pastes the two-dimensional code on the inner wall of the paper roll, so that after the paper roll is installed on the winding shaft, the weight of the paper roll is entered into the computer 103 using a code scanning device connected to the computer 103 for subsequent fineness calculation.

[0068] It should be noted that in actual application scenarios, finished fiber information is key data in the subsequent fiber use process. However, due to the possible differences in the data management systems used by fiber producers and fiber users, the product fiber information provided by the producer needs to be exported from the producer's data management system, processed, and then poured into the user's data management system before it can be used. However, by configuring the above-mentioned QR code printing device, this application can store the finished fiber information in the finished fiber information QR code. The user only needs to scan the finished fiber information QR code through the scanning device to obtain and use the finished fiber information, thereby improving data usage efficiency.

[0069] It should be noted that in actual application scenarios, the finished fiber information in the above-mentioned finished fiber information QR code may include, in addition to the above-mentioned export mark, fiber length, fiber fineness and fiber weight,: winding time, unwinding time, paper roll weight, fiber roll weight, breakpoint information, etc.

[0070] In one possible implementation, the above Figure 1 The titer detection system shown also includes:

[0071] Protocol conversion gateway, the length measuring device 101 is connected to the controller 102 through the protocol conversion gateway;

[0072] The protocol conversion gateway is used to convert the fiber length and fiber output rate in the first communication protocol format sent by the length measuring device 101 into the fiber length and fiber output rate in the second communication protocol format recognizable by the controller 102.

[0073] It should be noted that in actual application scenarios, since the controller 102 can be a custom-developed programmable logic controller, in order to meet the high time sensitivity and multiple data inputs of fiber production, bus technology is usually used for communication. The length-measuring device 101 is mostly a sensor that has completed basic configuration, and mostly uses a serial communication protocol. Therefore, the present application converts the fiber length and fiber output rate in the first communication protocol format sent by the length-measuring device 101 into the fiber length and fiber output rate in the second communication protocol format that can be recognized by the controller 102 by configuring a protocol conversion gateway. While achieving communication protocol compatibility, it avoids program adjustments to the length-measuring device 101 and the controller 102, thereby reducing the difficulty of application. Among them, the above-mentioned protocol conversion gateway can be a gateway device that converts the serial communication protocol Modbus to the automation bus protocol (PROFINET).

[0074] In one possible implementation, the above Figure 1 The titer detection system shown also includes:

[0075] At least one reset switch, the reset switch is electrically connected to the controller 102, and the reset switch has a corresponding relationship with the length measuring device 101;

[0076] The reset switch is used to send a reset trigger signal to the controller 102, so that the controller 102 resets the fiber length and fiber output rate collected by the length measuring device 101 corresponding to the reset switch to zero.

[0077] It should be noted that in actual application scenarios, after the production of one fiber roll is completed, the fiber roll needs to be removed from the winding mechanism and replaced with a new paper roll before the next fiber roll can be produced. However, during this process, the controller, the length-counting device and the fiber production line are not shut down. If the fiber roll production is started directly at this time, the length-counting device will accumulate the fiber length of the current fiber roll based on the fiber length of the fiber roll that has been produced. At the same time, it will also cause a long period of blankness in the appearance rate of the current fiber roll, affecting the calculation accuracy of the fineness of the current fiber roll. Therefore, the present application configures the above-mentioned reset switch, and configures the reset switch to send a reset trigger signal to the controller 102, so that the controller 102 sets the fiber length and fiber output rate collected by the length-counting device 101 corresponding to the reset switch to zero, thereby avoiding the influence of data accumulation on the calculation accuracy of fineness.

[0078] In a possible implementation, the reset switch may be a button switch that sends high and low level signals. Under normal operating conditions, the reset switch continuously sends a low level signal to the controller 102. When a reset is required, the production personnel press the reset button of the reset switch, so that the reset switch sends a high level signal to the controller 102, so that the controller 102 responds to the high level signal and the communication interface corresponding to the reset switch, determines the length measuring device 101 corresponding to the communication interface, and sends a reset signal to it, so that the length measuring device 101 sets the collected fiber length and fiber output rate to zero.

[0079] In one possible implementation, the above Figure 1 The titer detection system shown also includes:

[0080] An audible and visual alarm device, the audible and visual alarm device is electrically connected to the controller 102;

[0081] The sound and light alarm device is used to send out a sound and light alarm signal in response to the alarm trigger signal generated by the controller 102 when a breakpoint is detected.

[0082] It should be noted that, in actual application scenarios, the above-mentioned sound and light alarm can be configured in a one-to-one correspondence with the length measuring device 101, and the corresponding relationship between the sound and light alarm and the length measuring device 101 is stored in the controller 102. Since when the controller 102 detects a breakpoint, it indicates that the fiber bundle is broken, and the production personnel need to repair the breakpoint at this time. Therefore, the present application configures the sound and light alarm to respond to the alarm trigger signal generated by the controller 102 when the breakpoint is detected, and sends out a sound and light alarm signal to indicate the location of the breakpoint, thereby assisting the production personnel to quickly determine the breakpoint location and repair it, thereby improving production efficiency.

[0083] It should be noted that in actual application scenarios, the structural schematic diagram of the fiber size detection system provided by the first aspect of the present application and any possible implementation thereof can be as follows: Figure 2 As shown:

[0084] Assume that the fiber production line is configured with 8 fiber bundle outlets, numbered 01 to 08. Assume that two fiber bundle outlets share a protocol conversion gateway. Figure 2 The fiber size detection system shown includes: 8 length measuring devices 21, 4 protocol conversion gateways 22, 1 controller 23, 8 sound and light alarms 24, 8 reset switches 25, 1 computer 26, 8 electronic scales 27, 1 wireless barcode scanner 28 and 1 QR code printing device 29.

[0085] The length measuring devices 21 are respectively deployed at the exit positions of each fiber bundle. The length measuring devices 21 are connected to the controller 23 through the corresponding protocol conversion gateway 22, the sound and light alarm 24 is electrically connected to the controller 23, the reset switch 25 is electrically connected to the controller 23, the controller 23 is electrically connected to the computer 26, the wireless barcode scanner 28 is connected to the computer 26, the electronic scale 27 is connected to the computer 26, the electronic scale 27 is connected to the two-dimensional code printing device 29, and the two-dimensional code printing device 29 is connected to the computer 26. Among them, the above-mentioned sound and light alarm 24 can display the number of the corresponding length measuring device 21, and the reset switch 25 is marked with the number of the corresponding length measuring device 21.

[0086] In a possible implementation, only one electronic scale 27 may be provided. However, when only one electronic scale 27 is provided, production personnel are required to place the fiber roll or paper roll on the electronic scale 27 for weighing during use.

[0087] The second aspect of the present application provides a fineness detection method, which is applied to the fineness detection system as in the first aspect of the present application and any possible implementation thereof, such as Figure 3 As shown, the fineness detection method includes:

[0088] S301, the length measuring device collects the fiber length and fiber output rate of the fibers output from the target fiber bundle outlet, and sends the fiber length and fiber output rate corresponding to the target fiber bundle outlet to the controller.

[0089] S302, the controller records the breakpoint information corresponding to the target fiber bundle outlet based on the fiber output rate and the fiber length; and sends the fiber length and breakpoint information corresponding to the target fiber bundle outlet to the computer.

[0090] S303: When the fiber length reaches a preset length, the computer sends a weighing instruction to the electronic scale.

[0091] S304, the electronic scale measures the weight of the fiber roll of the winding mechanism in response to the weight measurement instruction, and sends the weight of the fiber roll to the computer.

[0092] S305, the computer calculates the fineness of the fibers output from the target fiber bundle outlet according to the fiber length, breakpoint information, and fiber roll weight sent by the electronic scale.

[0093] It should be noted that the present application records the breakpoint information by configuring the controller based on the fiber length and fiber output rate collected by the length measuring device, thereby avoiding the risk of information recording errors that may occur in the existing method of manually recording breakpoint information in large-scale production. Subsequently, by configuring the computer to calculate the fiber fineness output from the target fiber bundle outlet based on the fiber roll weight, fiber length and breakpoint information sent by the electronic scale, the present application can complete the fineness calculation on the production line without removing the fiber roll from the production line, thereby improving the fineness detection efficiency. It can be seen that the present application improves the fineness detection accuracy and detection efficiency.

[0094] In a possible implementation, the controller records the breakpoint information corresponding to the target fiber bundle outlet based on the fiber output rate and the fiber length, including:

[0095] When the controller detects that the fiber output rate of the target fiber bundle outlet at the first moment is 0, the controller records the time when the first breakpoint is generated;

[0096] When the controller detects that the fiber output rate of the target fiber bundle outlet at the second moment is 0, the controller records the second breakpoint generation time when the second breakpoint is generated, and the second moment is later than the first moment;

[0097] When the difference between the second breakpoint generation time and the first breakpoint generation time is less than the preset time threshold, the controller uses the difference between the fiber length at the first moment and the fiber length at the second moment as the fiber subtraction length;

[0098] The controller records the breakpoint information corresponding to the target fiber bundle outlet including the first breakpoint generation time, the second breakpoint time and the fiber reduction length.

[0099] It should be noted that in actual application scenarios, when a breakpoint occurs, the fiber bundle on the side of the breakpoint close to the winding mechanism continues to move toward the winding mechanism due to the traction of the winding shaft, while the fiber bundle on the side of the breakpoint close to the target fiber bundle outlet is not pulled by the winding shaft and cannot continue to move toward the winding mechanism. At this time, the length measuring device cannot detect the fiber bundle, and the fiber output rate is 0. Therefore, the present application realizes automatic detection of fiber bundle breakpoints by configuring the controller to record the moment when the breakpoint is generated when the fiber output rate is monitored to be 0.

[0100] It should be noted that in actual application scenarios, since too many consecutive breakpoints will affect the strength of the fiber bundle, the production staff will remove the fiber bundle between two breakpoints with a smaller interval when repairing, thereby reducing the breakpoints. However, the present application configures the controller to calculate the difference between the moment when the second breakpoint is generated and the moment when the first breakpoint is generated, and compares the difference with the preset time threshold, thereby marking the breakpoints with a smaller interval, and by configuring the difference to be less than the preset time threshold, the difference between the fiber length at the first moment and the fiber length at the second moment is used as the fiber subtraction length, thereby recording the length of the fiber bundle removed by the production staff, and then deducting the length of the removed fiber bundle from the total length of the fiber roll when calculating the fiber density, thereby improving the accuracy of the fiber density calculation.

[0101] In one possible implementation, the above Figure 3 The fiber size detection method shown also includes:

[0102] At least one reset switch sends a reset trigger signal to the controller, so that the controller resets the fiber length and fiber output rate collected by the length measuring device corresponding to the reset switch to zero.

[0103] In a possible implementation, the computer calculates the fineness of the fibers output from the target fiber bundle outlet according to the fiber length, breakpoint information, and fiber roll weight sent by the electronic scale, including:

[0104] The computer determines the difference between the fiber roll weight and the fiber roll paper tube weight as the fiber roll net weight;

[0105] The computer determines the difference between the fiber length and the subtracted length of each fiber in the breakpoint information as the net fiber length;

[0106] The computer obtains the quotient of the net weight of the fiber roll divided by the net length of the fiber, and determines the product of the quotient and a preset coefficient as the fineness of the fiber output from the target fiber bundle outlet.

[0107] In one possible implementation, the above Figure 3 The fiber size detection method shown also includes:

[0108] The protocol conversion gateway converts the fiber length and fiber output rate in the first communication protocol format sent by the length measuring device into the fiber length and fiber output rate in the second communication protocol format recognizable by the controller.
