[0002] In industrial production, the roll diameter measurement of coiled materials (such as paper, film, metal strip, etc.) is an important link. Traditional roll diameter measurement methods mainly rely on manual measurement, contact sensors or ultrasonic sensors.

Contact sensors need to contact the surface of the coil, and long-term use can easily cause sensor wear, affecting measurement accuracy, and requires regular maintenance and replacement, increasing production costs.

[0025] Please refer to Figure 1 , Figure 1 which is a schematic framework diagram of the coil material device provided by the embodiments of the present application.

[0026] In some embodiments, the coil material device includes a reel assembly 100, a swing rod assembly 200, an induction assembly 300, and a controller 500. The controller 500 is communicatively connected to the reel assembly 100, the swing rod assembly 200, and the induction assembly 300. The induction assembly 300 is arranged on the reel assembly 100 to sense the motion state of the reel assembly 100, and the swing rod assembly 200 is connected to the reel assembly 100.

[0027] It should be noted that the reel assembly 100 in the embodiments of the present application includes a plurality of winding and unwinding reels and a reel main shaft. During the unwinding process of the coil material device, the coil material is placed on the reel main shaft, and the unwinding process of the coil material is realized through the mutual cooperation of the plurality of winding and unwinding reels.

[0028] In some embodiments, the reel assembly 100 further includes an unwinding groove for guiding the movement of the coil material during unwinding, enabling the coil material to move along a predetermined path during unwinding, preventing the coil material from shifting or wrinkling during unwinding, thereby ensuring the flatness and unwinding quality of the coil material and ensuring that the coil material can be evenly and stably unwound.

[0029] The coil material device described in the embodiments of the present application is to more clearly illustrate the technical solutions of the embodiments of the present application and does not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Those skilled in the art will know that with the evolution of the coil material device and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are equally applicable to similar technical problems.

[0030] Those skilled in the art can understand that Figure 1 the coil material device shown in

[0031] Please refer to Figure 2 , Figure 2 which is a flowchart of the specific method of the coil diameter measurement method provided by the embodiments of the present application, applicable but not limited to Figure 1 the coil material device in

[0032] Step S101: Set a preset induction position on the reel assembly 100, control the rotation of the reel assembly 100 to drive the swing of the swing rod assembly 200, determine the swing arc length of the swing rod assembly 200, and record the induction signal and the number of inductions when the induction component 300 senses the preset induction position.

[0033] In step S101 of some embodiments, the embodiments of the present application first set a preset induction position on the reel assembly 100, that is, the position that the subsequent induction component 300 needs to sense. At the same time, control the rotation of the reel assembly 100. Due to the connection relationship between the reel assembly 100 and the swing rod assembly 200, the swing rod assembly 200 will swing as the reel assembly 100 moves during the rotation of the reel assembly 100. At this time, determine the swing arc length of the swing rod assembly 200 to facilitate the subsequent determination of the real-time coil diameter, and at the same time, be able to detect the tension change of the coil material on the reel assembly 100 in real time, avoiding problems such as wrinkling, breaking or loosening of the coil material due to uneven tension, and record the induction signal and the number of inductions when the induction component 300 senses the preset induction position, which is convenient for subsequent determination of the coil diameter value through the induction signal and the number of inductions.

[0034] Step S102: When the number of inductions reaches the preset number, determine the rotation duration according to the induction signals of two adjacent times.

[0035] In step S102 of some embodiments, when the number of inductions reaches a preset number, the rotation duration is determined according to two adjacent induction signals, so as to be able to determine the interval duration between two preset induction positions sensed by the reel assembly 100.

[0036] It should be noted that the preset number can be set by the user according to their needs. Among them, the preset number is greater than or equal to two, that is, the number of inductions of the induction component 300 to the preset induction position is greater than or equal to two.

[0037] It is worth noting that when the number of inductions does not reach the preset number, the reel assembly 100 will continue to be controlled to rotate at this time, so as to sense the preset induction position through the induction component 300 until the number of inductions reaches the preset number.

[0038] Step S103, obtain the rotation angle of the reel assembly 100, and determine the initial reel diameter value according to the swing arc length and the rotation angle.

[0039] In step S103 of some embodiments, the rotation angle of the reel assembly 100 is obtained. Specifically, the drive motor in the reel assembly 100 in the embodiments of the present application records the rotation angle of the rotating shaft assembly, and determines the initial reel diameter value according to the swing arc length and the rotation angle, so as to determine the initial reel diameter value, ensure the accuracy of subsequent reel diameter calculation, and reduce the cumulative error.

[0040] Step S104, determine the target reel diameter value according to the initial reel diameter value, the number of inductions, and the rotation duration.

[0041] In step S104 of some embodiments, the target reel diameter value is determined according to the initial reel diameter value, the number of inductions, and the rotation duration, so as to realize the real-time measurement of the reel diameter of the coil material. The accurate measurement and real-time measurement of the reel diameter can be directly realized through the initial reel diameter value, the number of inductions, and the rotation duration, without the need for redundant sensors for measurement, without contacting the surface of the coil material, avoiding the problem of sensor wear, and reducing the maintenance cost.

[0042] Please refer to Figure 3 , Figure 3 is a flowchart of a specific method for recording the induction signal and the number of inductions when the induction component 300 senses the preset induction position provided by an embodiment of the present application. In some embodiments, the method includes but is not limited to steps S201 to S202.

[0043] It should be noted that the reel assembly 100 includes a reel main shaft, the preset induction position is the position at the preset origin on the reel main shaft, and the induction component 300 includes an inductor. The inductor is separated from the preset origin by a first preset distance to record the position of the preset origin through the inductor.

[0044] It can be understood that the preset origin in the embodiments of the present application can be the physical origin of the reel main shaft or a custom virtual origin, and the first preset distance can be set according to the needs of the user so that the sensor can approach the preset origin. The embodiments of the present application do not make specific limitations on the setting of the preset origin and the first preset distance.

[0045] Step S201, within the first preset scanning period, sense the preset origin through the sensor and record the first sensing signal generated by the sensor.

[0046] Step S202, record all the first sensing signals generated by the sensor within the first preset scanning period to obtain the sensing signals, and record the number of times the sensor generates the first sensing signal to obtain the sensing times.

[0047] In steps S201 to S202 of some embodiments, during the process of recording the sensing signals and the sensing times when the sensing component 300 senses the preset sensing position, the sensor in the embodiments of the present application is set at a position of the first preset distance from the preset origin of the reel main shaft. During the rotation of the reel main shaft, the sensor will record the position of the preset origin and generate a sensing signal to latch the rotation time. Specifically, in the embodiments of the present application, the preset origin is sensed through the sensor within the first preset scanning period. Each time the sensor senses the preset origin, it will generate a first sensing signal. At this time, record the first sensing signal generated by the sensor, and then record all the first sensing signals generated by the sensor within the first preset scanning period to use all the first sensing signals as the sensing signals, and record the number of times the sensor generates the first sensing signal to obtain the sensing times, which is convenient for subsequent determination of the reel diameter value through the sensing signals and the sensing times.

In some embodiments, the method includes but is not limited to steps S301 to S302.

[0050] It should be noted that the reel assembly 100 includes a pay-off groove, the preset sensing position is the position at the connecting shaft of the pay-off groove, and the sensing component 300 includes a sensing piece, and the sensing piece is separated from the connecting shaft by a second preset distance to record the position at the connecting shaft through the sensing piece.

[0051] It can be understood that the connection shaft in the embodiment of the present application is the bearing connection part of the unwinding groove, and the second preset distance can be set according to the needs of the user so that the induction sheet can approach the connection shaft. The present application embodiment does not make specific limitations on the setting of the connection shaft and the second preset distance.

[0052] Step S301, within the second preset scanning period, the connection shaft of the unwinding groove is sensed by the induction sheet, and the second induction signal generated by the induction sheet is recorded.

[0053] Step S302, record all the second induction signals generated by the induction sheet within the second preset scanning period to obtain the induction signal, and record the number of times the induction sheet generates the second induction signal to obtain the induction times.

[0054] In steps S301 to S302 of some embodiments, during the process of recording the induction signal and the induction times when the induction component 300 senses the preset induction position, the induction sheet in the embodiment of the present application is set at a position of a second preset distance from the preset origin of the main shaft of the reel. During the rotation of the reel assembly 100, the induction sheet will record the position of the connection shaft of the unwinding groove and generate an induction signal to latch the rotation time. Specifically, in the embodiment of the present application, the preset origin is sensed by the induction sheet within the second preset scanning period. Each time the induction sheet senses the position of the connection shaft, a second induction signal will be generated. At this time, the second induction signal generated by the induction sheet is recorded, and then all the second induction signals generated by the induction sheet within the second preset scanning period are recorded, so as to use all the second induction signals as the induction signal, and record the number of times the induction sheet generates the second induction signal to obtain the induction times, which is convenient for subsequent determination of the reel diameter value through the induction signal and the induction times.

[0055] It can be understood that the induction sheet in the embodiment of the present application can be an electromagnetic induction sheet, a capacitive induction sheet, etc., and the second preset scanning period can be five seconds, ten seconds, twenty seconds, etc. The present application embodiment does not make specific limitations.

[0056] Please refer to Figure 5 , Figure 5 which is a flowchart of a specific method for determining the swing arc length of the swing rod assembly 200 provided by the embodiment of the present application. The method includes but is not limited to steps S401 to S403.

[0057] It should be noted that the swing rod assembly 200 includes a swing rod member and a sensor. Among them, the sensor can be a proximity switch, a photoelectric sensor, an ultrasonic sensor, etc., to realize non-contact measurement of the swing rod member.

[0058] Step S401, control the reel assembly 100 to rotate to drive the swing rod assembly 200 to swing, and sense the swing angle of the swing rod member during the swing process through the sensor.

[0059] Step S402: Determine the length of the strip during the rotation of the coil around the reel assembly 100 according to the swing angle.

[0060] Step S403: Determine the swing arc length of the swing rod assembly 200 according to the strip length.

[0061] In steps S401 to S403 of some embodiments, during the process of controlling the rotation of the reel assembly 100 to drive the swing of the swing rod assembly 200 and determining the swing arc length of the swing rod assembly 200, in the embodiments of the present application, first control the rotation of the reel assembly 100 to drive the swing of the swing rod assembly 200, and sense the swing angle of the swing rod member during the swing through a sensor. The non-contact measurement of the swing angle is realized through the sensor, and further the real-time recording of the swing angle of the swing rod member is realized, improving the measurement accuracy of the swing angle. Then, determine the length of the strip during the rotation of the coil around the reel assembly 100 according to the swing angle, so as to obtain the change of the strip during the rotation of the coil around the reel assembly 100, and further ensure the flatness and stability of the coil during the winding and unwinding process. After that, determine the swing arc length of the swing rod assembly 200 according to the strip length. Specifically, use the length of the strip moved during the rotation of the reel assembly 100 as the swing arc length of the swing rod assembly 200, so as to be able to detect the change of the tension of the coil on the reel assembly 100 in real time, and avoid problems such as wrinkles, breaks or slack of the coil due to uneven tension.

[0062] In some embodiments, during the process of determining the length of the strip during the rotation of the coil around the reel assembly 100 according to the swing angle, in the embodiments of the present application, the corresponding relationship between the swing angle and the strip length can be preset in advance, and then compare the swing angle with the preset corresponding relationship, and select the strip length corresponding to the swing angle, so as to realize the determination of the strip length. In addition, in the embodiments of the present application, the length of the swing member can also be obtained, and then the strip length can be calculated according to the length of the swing member and the swing angle, so as to realize the accurate determination of the strip length. The embodiments of the present application do not make specific limitations on the method for determining the strip length.

Specifically, the coil radius value is determined by the ratio of the swing arc length to the rotation radian. After that, the initial coil diameter value is determined based on the coil radius value. Specifically, the coil radius value is multiplied by 2 to obtain the initial coil diameter value, realizing the determination of the initial coil diameter value, ensuring the accuracy of subsequent coil diameter calculations, and reducing the cumulative error.

[0071] Step S602: Determine the target linear speed according to the initial coil diameter value and the motor speed.

[0072] Step S603: Determine the target rotation duration according to the number of induction times and the rotation duration.

[0073] Step S604: Determine the target coil diameter value according to the target rotation duration and the target linear speed.

[0074] In steps S601 to S604 of some embodiments, in the process of determining the target coil diameter value according to the initial coil diameter value, the number of induction times, and the rotation duration, the embodiment of the present application first obtains the motor speed of the drive motor in the reel assembly 100, then determines the target linear speed according to the initial coil diameter value and the motor speed, thereby obtaining the overall machine linear speed of the coil device, and then determines the target rotation duration according to the number of induction times and the rotation duration. Specifically, the embodiment of the present application can multiply the number of induction times by the rotation duration to determine the target rotation duration, thereby obtaining the time for the reel assembly 100 to rotate one week. After that, the target coil diameter value is determined according to the target rotation duration and the target linear speed. Specifically, the target coil diameter value can be obtained by directly multiplying the target rotation duration by the target linear speed, or can be obtained by integrating the target rotation duration and the target linear speed, realizing the accurate and real-time measurement of the coil diameter without the need for redundant sensors for measurement.

[0075] It is understandable that the process of determining the target coil diameter value will be specifically described in the embodiments of the present application below, and will not be elaborated herein.

[0076] Please refer to Figure 8 , Figure 8 which is a flowchart of a specific method for determining the target coil diameter value according to the target rotation duration and the target linear velocity provided by the embodiments of the present application. The method includes but is not limited to steps S701 to S702.

[0077] Step S701: Multiply the target rotation duration and the target linear velocity to obtain the circumference, and obtain the target coil diameter value according to the circumference and the pi.

[0078] In step S701 of some embodiments, in the process of determining the target coil diameter value according to the target rotation duration and the target linear velocity, the embodiments of the present application may first multiply the target rotation duration and the target linear velocity to obtain the circumference, and obtain the target coil diameter value according to the circumference and the pi. Specifically, multiply the target rotation duration by the target linear velocity to obtain the circumference, and then divide the circumference by π to obtain the target coil diameter value, so as to realize the real-time measurement of the coil diameter of the coil material, and can directly realize the accurate measurement and real-time measurement of the coil diameter through the rotation duration and the linear velocity, without the need for redundant sensors for measurement.

[0079] Step S702: Integrate the target rotation duration and the target linear velocity to obtain the target coil diameter value.

[0080] In step S702 of some embodiments, in the process of determining the target coil diameter value according to the target rotation duration and the target linear velocity, the embodiments of the present application may also integrate the target rotation duration and the target linear velocity to obtain the target coil diameter value, so as to reduce the problem of inaccurate coil diameter calculation caused by measurement errors and calculation errors, and improve the accuracy of coil diameter calculation.

[0081] Please refer to Figure 9 , Figure 9 which is a flowchart of a specific method for the coil diameter measurement method provided by another embodiment of the present application. The method includes but is not limited to step S801.

[0082] It should be noted that step S801 occurs after determining the target coil diameter value according to the initial coil diameter value, the number of induction times, and the rotation duration.

[0083] Step S801: Perform a limiting operation on the target coil diameter value based on a preset coil diameter limit value.

[0084] In step S801 of some embodiments, after determining the target coil diameter value based on the initial coil diameter value, the number of inductions, and the rotation duration, the embodiments of the present application further perform a limiting operation on the target coil diameter value based on a preset coil diameter limit value to achieve filtering processing of the target coil diameter value, preventing abnormal fluctuations in the calculated or measured coil diameter value, thereby affecting the stability and control accuracy of the system. Specifically, the coil diameter limit value in the embodiments of the present application includes a maximum limit value and a minimum limit value. The preset coil diameter limit value is compared with the target coil diameter value. When the target coil diameter value is greater than the maximum coil diameter value, the target coil diameter value is restricted; when the target coil diameter value is less than the minimum limit value, the target coil diameter value is also restricted; when the target coil diameter value is greater than or equal to the minimum limit value and less than or equal to the maximum limit value, the current target coil diameter value is maintained, thereby keeping the tension of the material constant. By limiting the processing, sudden changes in the coil diameter value are avoided, and the stability and reliability of the system are improved.

[0085] It should be noted that the coil diameter limit value in the embodiments of the present application can be set by the user according to their needs, and the embodiments of the present application do not make specific restrictions.
