[0028] Figure 1 The following is a flow chart of a method for detecting the remaining amount of a coil provided in an embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a method for detecting the remaining amount of a coil, which is applied to a system for detecting the remaining amount of a coil. The system includes a feeder and a distance measuring device. The feeder includes a roller, which is used to carry the coil. The distance measuring device is arranged toward the roller and is used to measure the distance from the outermost layer of the coil to the distance measuring device. The method may include the following steps.

[0029] Step S101, after detecting that a coil is loaded onto a feeder, obtaining coil information of the coil and a first distance collected by a distance measuring device;

[0030] Step S102, while the feeder is feeding the coil, obtaining a second distance collected by the distance measuring device;

[0031] Step S103: determining the remaining amount of the coil according to the first distance, the second distance and the coil information.

[0032] It can be understood that the coil remainder detection system is an intelligent system that integrates a feeder, a distance measuring device and a data processing unit. It is designed to monitor and manage the use of coils in real time to ensure the continuity and efficiency of the production process. Among them, the feeder includes a roller, which serves as a load-bearing and transmission component for the coils. The design of the roller should ensure that the coils remain stable during the feeding process to avoid sliding or deformation. Preferably, the roller can adopt a combination of a tapered shaft and a sliding sleeve. The shaft body is designed to be tapered, and the outer diameter can be adjusted by the sliding sleeve, so that it can adapt to coils of different sizes and inner diameters. This system calculates the coil remainder of the coil during the feeding operation by accurately measuring the distance from the outermost layer of the coil to the distance measuring device, combined with the initial parameters of the coil, such as thickness, width and inner diameter. Preferably, an alarm can be issued when necessary to remind the operator to replace the coil in time.

[0033] Specifically, after detecting that a coil has been loaded onto the feeder, the processor can obtain coil information. This information may include, but is not limited to, the initial total thickness, initial total length, initial weight, inner diameter, thickness, and width of the coil. This coil information can be input by a staff member. Simultaneously, the processor obtains the first distance measured by the distance measuring device after the coil is loaded. This distance represents the initial distance from the outermost layer of the coil to the distance measuring device before consumption begins. The outermost layer of the coil is the layer away from the axis.

[0034] Furthermore, during the process of the feeder feeding the coil, the second distance collected by the distance measuring device is continuously or periodically obtained. The second distance changes continuously as the coil is consumed, representing the distance from the current outermost layer of the coil to the distance measuring device. The second distance collected by the distance measuring device increases as the coil is consumed. Then, based on the second distance collected in real time, the known coil information and the first distance, the remaining coil amount can be calculated. The remaining coil amount can be the remaining weight of the coil, the remaining volume of the coil or the remaining length of the coil. In one example, the real-time remaining total thickness of the coil can be determined based on the real-time collected second distance combined with the first distance and the initial total thickness of the coil. The remaining volume of the coil can be calculated based on the real-time remaining total thickness, the inner diameter of the coil and the width of the coil.

[0035] In another example, the initial volume of the coil can be calculated based on the initial parameters of the coil, and the remaining weight of the coil can then be determined based on the initial volume, remaining volume, and initial weight of the coil. In yet another example, the remaining length of the coil can be determined based on the initial volume, remaining volume, and initial length of the coil. In this way, the above method enables real-time and accurate monitoring of the remaining coil, allowing workers to promptly understand the remaining coil status and load materials in a timely manner, thereby improving production efficiency.

[0036] The above technical solution is applied to a system for detecting the remaining amount of coiled material. The system includes a feeder and a distance measuring device. The feeder includes a roller for carrying the coiled material. The distance measuring device is arranged toward the roller and is used to measure the distance from the outermost layer of the coiled material to the distance measuring device. After detecting that the coiled material is loaded onto the feeder, the coiled material information of the coiled material and the first distance collected by the distance measuring device are obtained. Then, during the process of the feeder feeding the coiled material, the second distance collected by the distance measuring device is obtained. Finally, the remaining amount of the coiled material is determined based on the first distance, the second distance and the coiled material information. This application can automatically monitor the remaining amount of the coiled material in real time during the operation of the feeder, and the monitoring results are highly accurate.

[0037] In an embodiment of the present application, an information identification code is set on the coil, and the system may further include a scanning device for scanning the information identification code on the coil to obtain the coil information of the coil; obtaining the coil information of the coil may include: obtaining the coil information of the coil collected by the scanning device.

[0038] It is understood that in order to achieve automated collection of coil information, an information identification code for recording coil information is provided on the coil in the embodiment of the present application. The information identification code can be a barcode, a QR code, etc. At the same time, the coil residual material detection system has a new scanning device, which can be used to scan the information identification code on the coil to automatically obtain the coil information.

[0039] In this way, by adding information identification codes to the coils, adding scanning devices and optimizing system processes, the automatic collection of coil information and real-time and accurate monitoring of coil remainder are achieved, effectively improving production efficiency and resource utilization.

[0040] In an embodiment of the present application, the coil information includes the initial total thickness of the coil and the inner diameter of the coil; the coil remainder is determined based on the first distance, the second distance and the coil information, including: determining the remaining total thickness of the coil based on the first distance, the second distance and the initial total thickness of the coil, the remaining total thickness of the coil being the difference between the sum of the first distance and the initial total thickness of the coil and the second distance; determining the coil remainder based on the remaining total thickness of the coil and the inner diameter of the coil.

[0041] It can be understood that the initial total thickness of the coil refers to the total thickness of the coil before use, the inner diameter of the coil refers to the radius of the hollow circle of the inner layer of the coil, and the width of the coil refers to the width of the coil sheet. After measuring the first distance using a distance measuring device and obtaining the second distance in real time during the feeding operation, the remaining coil amount can be determined based on the first and second distances combined with the coil information of the coil. Specifically, the remaining total thickness of the coil is first determined based on the first distance, the second distance, and the initial total thickness of the coil. Considering that the distance measuring device measures the distance from the outermost layer of the coil to the distance measuring device, and the initial total thickness of the coil is the total thickness from the inner surface of the coil to the outermost layer, the remaining total thickness of the coil = (first distance + initial total thickness of the coil) - second distance. Furthermore, based on the calculated remaining total thickness of the coil and the known inner diameter of the coil, the remaining coil amount is further determined. In one example, the remaining annular area can be calculated using the remaining total thickness and the inner diameter, and then combined with other coil information to calculate the remaining coil amount according to needs.

[0042] It's important to note that when calculating the remaining total thickness of a coil, the accuracy of the distance measuring device must be ensured, and any deformation of the coil due to use must be considered. Furthermore, the calculation method or parameter settings can be adjusted to suit different testing requirements, depending on the specific application scenario and coil type.

[0043] In this way, the coil remainder detection system can realize accurate monitoring and management of coil remainder, thereby improving production efficiency and resource utilization.

[0044] In an embodiment of the present application, the coil remainder is the remaining volume of the coil, and the coil information also includes the coil width; the coil remainder is determined based on the remaining total thickness of the coil and the inner diameter of the coil, including: determining the remaining volume of the coil based on the remaining total thickness of the coil, the inner diameter of the coil and the width of the coil.

[0045] It is understood that the remaining coil volume can be the remaining coil volume. Coil information can also include the initial total coil thickness, coil inner diameter, and coil width. Specifically, since the inner layer of the coil is a hollow circle, the current outer diameter of the coil can be obtained based on the remaining total coil thickness and coil inner diameter. Then, the remaining coil volume can be determined based on the coil inner diameter, current outer diameter, and coil width.

[0046] In an embodiment of the present application, the coil remainder is the remaining weight of the coil, and the coil information also includes the initial weight of the coil; the coil remainder is determined based on the remaining total thickness of the coil and the inner diameter of the coil, including: determining the initial cross-sectional area of the coil based on the inner diameter of the coil and the initial total thickness of the coil; determining the remaining cross-sectional area of the coil based on the remaining total thickness of the coil and the inner diameter of the coil; determining the remaining weight of the coil based on the remaining cross-sectional area, the initial cross-sectional area and the initial weight of the coil.

[0047] It is understood that coil information can also include the initial total thickness, inner diameter, and initial weight of the coil. Specifically, since the inner layer of the coil is a hollow circle, the initial outer diameter of the coil can be derived from the initial total thickness and inner diameter of the coil. The initial cross-sectional area of the coil can then be determined based on the inner diameter and initial outer diameter. Similarly, after calculating the remaining total thickness of the coil, the remaining cross-sectional area of the coil can be calculated based on the remaining total thickness and inner diameter of the coil. If the remaining coil weight is the remaining weight of the coil, the remaining coil weight can be determined based on the remaining cross-sectional area, the initial cross-sectional area, and the initial weight of the coil. The remaining coil weight is the product of the ratio of the remaining cross-sectional area to the initial cross-sectional area and the initial weight of the coil.

[0048] In an embodiment of the present application, the coil remainder is the remaining length of the coil, and the coil information also includes the initial length of the coil; the coil remainder is determined based on the remaining total thickness of the coil and the inner diameter of the coil, including: determining the initial cross-sectional area of the coil based on the inner diameter of the coil and the initial total thickness of the coil; determining the remaining cross-sectional area of the coil based on the remaining total thickness of the coil and the inner diameter of the coil; determining the remaining length of the coil based on the remaining cross-sectional area, the initial cross-sectional area and the initial length of the coil.

[0049] In one example, the coil information may further include the initial coil length. If the coil remainder is the remaining coil length, the remaining coil length is the product of the ratio of the remaining cross-sectional area to the initial cross-sectional area and the initial coil length.

[0050] Alternatively, to more intuitively represent the remaining coil, the remaining ratio can be used: coil remaining = remaining volume / initial volume × 100%. This allows real-time monitoring of the coil consumption ratio and remaining ratio.

[0051] In this way, the coil remainder detection system of this embodiment can achieve accurate monitoring and management of the coil remainder, thereby improving production efficiency and resource utilization, and reducing waste and costs.

[0052] In an embodiment of the present application, the system may further include an alarm device, and the method may further include: when it is detected that the remaining amount of the coiled material is less than a preset amount, outputting an alarm message through the alarm device.

[0053] As will be appreciated, to further enhance the functionality and practicality of the coil remaining amount detection system, an alarm device has been added to the coil remaining amount detection system in the embodiments of the present application. The processor can compare the coil remaining amount calculated in real time with a preset coil remaining amount and, if it detects that the coil remaining amount is less than the preset amount, output an alarm message through the alarm device. The preset coil remaining amount can be determined based on actual operating conditions. In one example, the alarm message can be output using sound, text, or light. This allows operators to be promptly alerted to take appropriate measures, thereby avoiding production interruptions or waste of resources.

[0054] In one example, when monitoring the remaining amount of coiled materials, the consumption rate of different coiled materials is different. Therefore, the coil remaining amount monitoring threshold can be set through experiments based on the properties of the coiled materials themselves and recorded in the information identification code. For example, the corresponding remaining volume threshold, remaining weight threshold, and remaining length threshold are set. When the remaining amount of coiled materials is less than the corresponding threshold, an alarm message is output through the alarm device to prompt the operator to load the materials in time and improve work efficiency.

[0055] In a specific embodiment of the present application, a system and method for detecting the remaining amount of a feeder coil based on a high-precision laser ranging sensor and an intelligent gateway are provided. The system includes a high-precision laser ranging sensor, a scanning gun and an intelligent gateway. The high-precision laser ranging sensor and the scanning gun both communicate with the intelligent gateway, and a QR code that records the coil information is provided on the coil.

[0056] Specifically, after the coil is loaded onto the feeder, the coil's QR code can be scanned with a scanner to obtain coil information, including the initial total thickness, initial weight, inner diameter, foil thickness, and foil width. Simultaneously, a high-precision laser distance sensor is installed to measure the first distance to the coil's outermost foil layer. After the feeder begins feeding, the high-precision laser distance sensor measures the second distance from the coil's outermost foil layer to the laser distance sensor in real time. Since the coil is a hollow circle and is mounted on a roller, the roller drives the coil to roll and feed. The first distance measured by the laser distance sensor plus the initial total thickness of the coil, minus the second distance, yields the real-time total thickness of the coil. The real-time outer diameter of the coil is the real-time total thickness plus the inner diameter of the coil.

[0057] Furthermore, the intelligent gateway can obtain the initial coil information of the coil scanned and the distance information measured by the laser ranging sensor. Based on the above data, the volume change of the coil can be calculated in real time, thereby inferring the remaining coil amount. When the remaining coil amount is less than the preset lower limit, the warning light will be used to alert on-site workers to change the material of the feeder in time. At the same time, all real-time calculated coil amount data will be stored by the intelligent gateway or reported to the upper application system.

[0058] An embodiment of the present application also provides a processor configured to execute the method for detecting the remaining amount of coiled material in the above embodiment.

[0059] The present application also provides a system for detecting the remaining amount of a coiled material, which may include:

[0060] Feeder, the feeder includes rollers, the rollers are used to carry the coils;

[0061] a distance measuring device, disposed toward the roller and used to measure the distance from the outermost layer of the coil to the distance measuring device;

[0062] The processor in the above embodiment.

[0063] Specifically, the coil remainder detection system is an intelligent system that integrates a feeder, a distance measuring device and a processor. It is designed to monitor and manage the use of coils in real time to ensure the continuity and efficiency of the production process. The feeder includes rollers, which serve as the load-bearing and transmission components of the coils. The design of the rollers should ensure that the coils remain stable during the feeding process and avoid sliding or deformation. The distance measuring device is set towards the rollers and is used to measure the distance from the outermost layer of the coil to the distance measuring device. The distance measuring device can communicate with the processor and send the collected data to the processor. The processor, as a data processing unit, can process the received data according to a preset program to determine the coil remainder. This system calculates the coil remainder of the coil during the feeding operation by accurately measuring the distance from the outermost layer of the coil to the distance measuring device, combined with the initial parameters of the coil, such as thickness, width and inner diameter. Preferably, an alarm can be issued when necessary to remind the operator to replace the coil in time.

[0064] In the embodiment of the present application, an information identification code is provided on the coil, and the system may further include:

[0065] The scanning device is used to scan the information identification code on the coil to obtain the coil information of the coil.

[0066] It is understood that, in order to achieve automated collection of coil information, the coil in the embodiment of the present application is provided with an information identification code for recording the coil information. The information identification code can be a barcode, a QR code, etc. The coil residual material detection system also includes a scanning device that can be used to scan the information identification code on the coil to automatically obtain the coil information. Preferably, the scanning device can be a mobile scanning device, such as a barcode scanner, to enhance the flexibility of the system.

[0067] In this way, by adding information identification codes to the coils, adding scanning devices and optimizing system processes, the automatic collection of coil information and real-time and accurate monitoring of coil remainder are achieved, effectively improving production efficiency and resource utilization.

[0068] In an embodiment of the present application, the system may further include: an alarm device for outputting alarm information.

[0069] As will be appreciated, to further enhance the functionality and practicality of the coil remaining amount detection system, embodiments of the present application incorporate an alarm device, which can communicate with the processor. The processor can compare the coil remaining amount calculated in real time with a preset coil remaining amount and, if it detects that the coil remaining amount is less than the preset amount, send an alarm command to the alarm device. Upon receiving the alarm command, the alarm device can output an alarm message. The alarm message can be output in the form of sound, text, or light. This allows operators to be promptly alerted to take appropriate measures, thereby avoiding production interruptions or waste of resources.

The barcode scanner, high-precision laser ranging sensor, and alarm device all communicate with the processor via an intelligent gateway. This allows for real-time and accurate monitoring of the feeder's coil remaining, as well as alarm and information reporting, by adding a high-precision laser ranging sensor and intelligent gateway.
