Description

Technical Field

[0001] This application belongs to the technical field of cable processing auxiliary devices, and particularly relates to a meter counter system. Background Technology

[0002] Cable length measurement is often required during cable production. Existing cable metering systems mainly utilize the friction between the cable and the measuring wheel to rotate the measuring wheel, and then calculate the actual length of the cable based on the number of rotations of the measuring wheel.

[0003] In actual production, after prolonged use, gaps often appear between the pressure roller and the cable being measured, causing the cable and the measuring roller to not fit tightly together, or insufficient friction between the measuring roller and the cable causes slippage between the cable and the measuring roller, resulting in a decrease in measurement accuracy.

[0004] Therefore, there is an urgent need for a new meter counter system to solve the problem of decreased measurement accuracy caused by gaps between components, wear and tear during use, and slippage in existing meter counters. Utility Model Content

[0005] This application provides a meter counter system that can solve the problem of decreased measurement accuracy caused by gaps between components, wear and tear during use, and slippage in existing meter counters.

[0006] This application provides a meter counter system, including: A marking device, installed on the cable production line, is used to mark the surface of the cable at preset time intervals. An identification device is installed between the marking device and the traction device of the cable production line, with the identification end of the identification device facing the cable. The identification device is used to identify markings on the cable; and The data processing device is electrically connected to the identification device, the marking device, and the rotary drive device in the traction device. The data processing device can receive the marking data collected by the identification device and the operating data of the rotary drive device, and determine the time interval based on the marking data identified by the identification device. The data processing device can determine the cable speed based on the marking data, operating data, the drum diameter in the winding device, and the cable diameter, thereby determining the cable length.

[0007] Optionally, the meter counter system also includes a distance measuring device with its measuring end facing the drum. The distance measuring device is used to measure the real-time distance between the distance measuring device and the cable surface when the drum is winding the cable.

[0014] Optionally, the data processing device is a programmable logic controller.

[0015] Optionally, the meter counter system may also include a meter counter.

[0016] The meter counter system provided in this application, when in use, uses a marking device to mark the cables running on the cable production line at fixed intervals. The identification device captures the marks and transmits them to the data processing device. The data processing device calculates the actual time interval based on the mark data transmitted by the identification device, and calculates the cable running speed by combining the operating data of the rotary drive device, the drum diameter, the drum working surface length, and the cable diameter.

[0028] Currently, existing meter counters suffer from reduced measurement accuracy due to gaps between components, wear and tear during use, and slippage.

[0029] To address the aforementioned problems, one embodiment of this application provides a meter counter system, such as... Figure 1 As shown, the meter counting system includes a marking device 1, an identification device 2, and a data processing device 3. The marking device 1 is installed on the cable production line and is used to mark the cable surface at preset time intervals. The identification device 2 is installed between the marking device 1 and the traction device of the cable production line, with the identification end of the identification device 2 facing the cable. The identification device 2 is used to identify the markings on the cable. The data processing device 3 is electrically connected to the identification device 2, the marking device 1, and the rotary drive device in the traction device. The data processing device 3 can receive the marking data collected by the identification device 2 and the operating data of the rotary drive device, and determine the time interval based on the marking data identified by the identification device 2. The data processing device 3 can determine the cable speed based on the marking data, operating data, the diameter of the drum 41 in the winding device 4, and the cable diameter, thereby determining the cable length.

[0030] The meter counter system provided in this application uses a marking device 1 to mark the cables running on the cable production line at fixed intervals. The identification device 2 captures the marks and transmits them to the data processing device 3. The data processing device 3 calculates the actual time interval based on the mark data transmitted by the identification device 2, and calculates the cable running speed by combining the operating data of the rotary drive device, the diameter of the drum 41, the working surface length of the drum 41, and the cable diameter. Combined with the number of marks captured by the identification device 2, the cable length is accurately calculated, thus achieving accurate measurement of the cable length. Because this application uses the above-mentioned non-contact cable method for cable length calculation, no material is consumed and the measurement is accurate.

[0031] Specifically, the cable speed when the drum 41 winds the first layer of cable can be calculated by using the operating data of the rotary drive device and the diameter of the drum 41. By combining the cable diameter and the axial length of the working surface of the drum 41, the number of layers of cable wound on the drum 41 and the actual diameter of the drum 41 can be calculated. Combined with the operating speed of the rotary drive device, the cable speed can be calculated in real time. The time interval and the real-time cable speed when the current mark passes the identification device 2 are determined based on the markings of the marking device 1 and the number of marks passed by the identification device 2, as well as the cable length when passing the corresponding number of marks.

[0032] It should be noted that the above-mentioned operating data includes the rotational speed of the output shaft of the rotary drive device. The above-mentioned data processing device 3 receives operating data, marking data, drum 41 diameter data, drum 41 working surface axial length data and cable diameter data, and determines the time interval, the real-time speed of the cable when the current mark passes the identification device 2, the number of marks passing the identification device 2, and the length of the cable when passing the corresponding number of marks. These are functions that the data processing device 3 itself has.

[0033] Understandably, the data processing device 3 is capable of receiving manually input data on the diameter of the drum 41, the axial length of the working surface of the drum 41, and the cable diameter.

[0034] It should also be noted that the above calculation methods are all mathematical means or calculation methods commonly used by those skilled in the art, and will not be elaborated on further here.

[0035] In some embodiments of this application, such as Figure 2 As shown, the meter counter system also includes a distance measuring device 5. The measuring end of the distance measuring device 5 faces the drum 41. The distance measuring device 5 is used to measure the real-time distance between the distance measuring device 5 and the cable surface when the drum 41 is winding the cable. The distance measuring device 5 is electrically connected to the data processing device 3.

[0036] The aforementioned distance measuring device 5 is used to measure the real-time distance between the distance measuring device 5 and the outer cable during the cable winding process of the drum 41 and transmit it to the data processing device 3. The data processing device 3 calculates the real-time diameter of the drum 41 and the cable as a whole during the cable winding process based on the real-time distance data, calculates the real-time speed of the cable by combining the running speed of the rotation drive device, and calculates the time by combining the number of marks transmitted by the marking device, thereby obtaining the cable length.

[0037] It should be noted that the functions of the data processing device 3 itself include receiving real-time distance data transmitted by the ranging device 5 to calculate the real-time diameter, combining the running speed of the rotating drive device to calculate the real-time speed, combining the marking data transmitted by the marking device to perform time calculation, and calculating the cable length.

[0038] In some embodiments of this application, such as Figure 3 As shown, there are multiple ranging devices 5, which are spaced apart along the axial direction of the drum 41.

[0039] The aforementioned distance measuring device 5 is equipped with multiple devices to further ensure data accuracy. Since the cable is wound layer by layer on the drum 41, when a layer is not completely wound, the overall diameter of the cable and the drum 41 is still at the current layer. The data that affects the overall linear speed of the cable and the drum 41 is the diameter of the current layer. Therefore, the data processing device 3 will select the real-time distance data with the smallest value among the multiple distance measuring devices 5 for calculation, which can better measure the cable length.

[0040] It should be noted that the data processing device 3 has the function of receiving real-time distance data from multiple ranging devices 5 and taking the smallest value among these real-time distance data for calculation.

[0041] In some embodiments of this application, the ranging device is a laser rangefinder, the laser emitting end of the laser rangefinder is oriented toward the outer diameter of the drum, and the line of the laser emitted by the laser emitting end is perpendicular to the axis of the drum 41 and intersects the axis of the drum.

[0042] Because laser rangefinders on the market offer high cost-effectiveness, the above-mentioned ranging device saves production costs for laser rangefinders while ensuring measurement accuracy.

[0043] In some embodiments of this application, the marking device is an inkjet printer.

[0044] The aforementioned inkjet printer can be the inkjet printer that comes with the meter counter system of this application, or it can be an inkjet printer in a cable production line that needs to print on the cable and print at fixed time intervals.

[0045] In some embodiments of this application, the identification device is a vision device.

[0046] The aforementioned identification device is a vision device, which can effectively identify the marked data. It only needs to be able to identify the existence of the marked data and does not require excessively high precision. Using a vision device can save production costs while completing the identification of the marks.

[0047] For example, the vision device described above can be an industrial camera.

[0048] In some embodiments of this application, an illumination source (not shown) is also included to provide auxiliary illumination for the identification device.

[0049] The aforementioned lighting source is used to provide illumination for the vision device and ensure its normal operation.

[0050] For example, the lighting source described above can be an LED light.

[0051] In some embodiments of this application, as shown in the figures, the meter counter system further includes a display device (not shown in the figures), which is electrically connected to the data processing device.

[0052] The aforementioned display device is capable of receiving and displaying cable length data, real-time cable data, etc., transmitted by the data processing device 3.

[0053] For example, the display device described above is a display.

[0054] It should be noted that transmitting cable length data and real-time cable data to the display device is a function inherent to the data processing device itself.

[0055] In some embodiments of this application, the data processing device is a programmable logic controller.

[0056] The programmable logic controller (PLC) has excellent reliability and stability in industrial environments, strong resistance to electromagnetic interference, and can operate continuously for long periods in a workshop environment. In addition, the PLC's computing power is sufficient to meet the data processing requirements of this application. Furthermore, the PLC has powerful integrated control capabilities and can simultaneously connect to multiple devices such as the aforementioned marking devices and identification devices. Moreover, the PLC adopts a modular structure, which is easy to expand and maintain.

[0057] In some embodiments of this application, the meter counter system also includes a meter counter (not shown in the figures).

[0058] The aforementioned meter counter is a commonly used meter counter in the prior art, used to measure cable length. The meter counter is used to assist in cable length measurement, as well as to measure cable length during the maintenance or repair of marking devices, identification devices, and data processing devices.

[0059] It should be noted that the above-mentioned meter counter is a commonly used device in this field, and its specific structure, installation position in the cable production line, and usage method will not be described in detail here.

[0060] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
