Description

Technical Field

[0001] This invention relates to the field of turntable technology, and more specifically to a weighing system and its application for a double-roller turntable. Background Technology

[0002] Chinese patent CN 210012446 U discloses a cable turntable status detection device, which includes a cable, a cable turntable, a motor for driving the cable turntable to rotate, and a brush that cooperates with the motor. The side of the cable turntable has a column, and a first arc-shaped guide mechanism and a second arc-shaped guide mechanism are symmetrically distributed on the column, gradually moving away from the column from top to bottom. The free end of the cable passes through a cable slip ring. A first direction limit switch and a second direction limit switch are respectively distributed on the first arc-shaped guide mechanism and the second arc-shaped guide mechanism.

[0003] In the existing technology, the weighing system for turntables has the problem of occupying a large space when it adopts a single roller structure, while when it adopts a double roller structure, the turntable needs to rotate, which makes it inconvenient to wire the load cells installed on it. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned above in the background art, and to propose a weighing system and its application for a double-roller turntable.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A weighing system for a double-roller turntable, characterized in that it comprises:

[0007] The base has a ring structure, and a double roller mechanism is provided on the top surface of the base. Multiple double roller mechanisms are arranged in a ring array, and are denoted as i. A turntable is installed on the double roller mechanism.

[0008] The double-roller mechanism includes:

[0009] Support rollers are installed on both sides of the support rollers, and a base is installed on the top of the support rollers. The support rollers are rotatably connected to the base, and the base is connected to the turntable.

[0010] A weighing sensor is installed on the base 1.

[0011] As a further embodiment of the present invention: where i is a positive integer, i = 1, 2, 3...n.

[0012] As a further embodiment of the present invention: two weighing sensors 3 are provided, and the two weighing sensors 3 are arranged adjacent to each other.

[0013] An application of a weighing system for a double-roller turntable includes the following:

[0014] The data acquisition module obtains the real-time weight data of the turntable when it is retracting the cable, and marks it as the weighing value Zci;

[0015] The weighing module obtains the weighing value Zci from the acquisition module, adds them together, and calculates the weight value GX of the turntable when winding the cable.

[0016] The storage module acquires and saves the weighing value Zci of the weighing sensor during the weighing period.

[0017] The analysis module obtains the weighing value Zci from the storage module and analyzes the cable quality by measuring the quantity of the weighing value Zc during the cable winding process.

[0018] As a further aspect of the present invention: the obtained cable weight value Gx is compared with the cable weight threshold.

[0019] If the value is greater than 1, a shutdown signal will be generated.

[0020] If it is less than, an entanglement signal is generated.

[0021] As a further aspect of the present invention, the specific working process of the analysis module is as follows:

[0022] The weight of the cable when the double roller mechanism rotates one revolution is calculated using the formula ZXQ=Zci*i, and recorded as the cable weight value per revolution ZXQ.

[0023] Compare the obtained cable weight value ZXQ per loop with the range of cable weights per loop.

[0024] If the weight value ZXQ of each loop of cable is greater than the weight range of each loop of cable, a signal indicating that the weight of that loop of cable is relatively heavy is generated.

[0025] If the weight value ZXQ of each loop of cable is within the range of the weight of each loop of cable, a qualified signal for that loop of cable is generated.

[0026] If the weight value ZXQ of each loop of cable is less than the weight range of each loop of cable, a signal indicating that the weight of that loop of cable is relatively light is generated.

[0027] The signals indicating that the cable loop is heavier or lighter are marked as unqualified signals.

[0028] As a further aspect of the present invention: when a signal indicating that the cable is defective is received, the standard value of the cable weight ZXB is obtained;

[0029] The weight difference of the measured segment of the cable loop is calculated using the formula CQYi=Zci-ZXB and recorded as the loop segment difference CQYi.

[0030] Compare the obtained segment difference value CQYi with the segment difference value range;

[0031] If the segment difference CQYi is greater than the segment difference range, a signal indicating that the cable segment is heavier is generated.

[0032] If the segment difference CQYi is within the segment difference range, the cable segment is considered qualified.

[0033] If the segment difference CQYi is less than the segment difference range, a signal indicating that the cable segment is lighter is generated.

[0034] The beneficial effects of this invention are:

[0035] The weighing system for the double-roller turntable of the present invention has the advantage of saving space compared with the single-roller weighing system by setting two roller structures; however, the setting of the weighing sensor in this weighing system requires the existing double-roller turntable to rotate during the weighing process, which leads to the problem of inconvenient wiring of the weighing sensor.

[0036] The application of the weighing system for the double-roller turntable of this invention obtains real-time cable weighing data and performs real-time calculation and analysis on the weighing data to obtain the cable weight data, and achieves real-time online monitoring of the turntable during the winding process, avoiding overload when the turntable is wrapped, which may cause the turntable to malfunction.

[0037] The measurement data obtained by the weighing sensor is then analyzed on a holistic basis for each loop. When a fault is detected, the cable of that loop is analyzed segment by segment to determine which specific area has a quality problem. Therefore, the application of this weighing system can quickly and accurately mark the faulty area, making it easy to find the fault after winding. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see Figure 1-3 As shown, the present invention is a weighing system for a double-roller turntable, including a base 1 and a double-roller mechanism 2;

[0046] The base 1 is a ring structure and is installed on the weighing platform. A double roller mechanism 2 is set on the top surface of the base 1. Multiple double roller mechanisms 2 are arranged in a ring array and are denoted as i, where i is a positive integer, i = 1, 2, 3...n. A turntable is installed on the double roller mechanism 2.

[0047] The double roller mechanism 2 includes a roller 22, a base 23, and a base 23. Rollers 22 are installed on both sides of the roller 22, and the base 23 is installed on the top of the roller 22. The roller 22 is rotatably connected to the base 1, and the base 23 is connected to the turntable.

[0048] Among them, a weighing sensor 3 is provided on the base 1. There are two weighing sensors 3, and the two weighing sensors 3 are arranged adjacent to each other.

[0049] The weighing system for the double-roller turntable of the present invention has the advantage of saving space compared with the weighing system with a single-roller 22 by setting two rollers 22. However, the setting of the weighing sensor 3 in this weighing system requires the existing double-roller turntable to rotate during the weighing process, which leads to the problem of inconvenient wiring of the weighing sensor 3.

[0050] Example 2

[0051] Based on the above embodiment 1, the present invention provides an application of a weighing system for a double-roller turntable, comprising:

[0052] The data acquisition module obtains real-time weight data of the turntable during cable winding.

[0053] Since the turntable rotates along the base 11 via the double roller mechanism 2, the weighing sensor 3 will measure the weighing value Zci for each rotation of (360 / i)°.

[0054] The weighing module obtains the weighing value Zci from the acquisition module, adds them together, and calculates the weight value GX of the turntable when winding the cable.

[0055] The obtained cable weight value Gx is compared with the cable weight threshold.

[0056] If the cable weight value Gx is greater than the cable weight threshold, it means that the weight of the cable winding on the turntable is too large and exceeds the turntable's bearing capacity, generating a stop signal.

[0057] If the cable weight value Gx is less than the cable weight threshold, it means that the weight of the cable being wound on the turntable is too small and does not exceed the turntable's bearing capacity. The winding work can continue and a winding signal will be generated.

[0058] The cable weight threshold is set by technicians based on actual production, and the cable weight threshold is preferably no more than 8-10% of the actual standard load capacity of the turntable.

[0059] The storage module acquires and saves the weighing value Zci of the weighing sensor 3 during the weighing period.

[0060] The analysis module obtains the weighing value Zci from the storage module and analyzes the cable quality by measuring the quantity of the weighing value Zc during the cable winding process of the turntable.

[0061] The specific working process of this analysis module is as follows:

[0062] Step 1: Obtain the weighing value Zci in the storage module, and calculate the cable weight when the double roller mechanism 2 rotates one revolution using the formula ZXQ=Zci*i, and record it as the cable weight value ZXQ per revolution;

[0063] Step 2: Compare the obtained weight value ZXQ for each loop of cable with the range of weight values ​​for each loop of cable;

[0064] If the weight value ZXQ of each loop of cable is greater than the weight range of each loop of cable, it indicates that the weight of the loop of cable is too heavy, and a signal indicating that the weight of the loop of cable is too heavy is generated.

[0065] If the weight value ZXQ of each loop of cable is within the range of the weight of each loop of cable, it means that the weight of the loop of cable being wound meets the requirements, and a qualified signal for the loop of cable is generated.

[0066] If the weight value ZXQ of each loop of cable is less than the weight range of each loop of cable, it means that the weight of the loop of cable is too light, and a signal indicating that the weight of the loop of cable is too light is generated.

[0067] The signals indicating that the cable loop is heavier or lighter are marked as unqualified signals for that loop of cable.

[0068] Step 3: When a signal indicating that the cable is defective is received, obtain the standard cable weight value ZXB;

[0069] The weight difference of the measured segment of the cable loop is calculated using the formula CQYi=Zci-ZXB and recorded as the loop segment difference CQYi.

[0070] The standard value for cable weight is obtained in the following way:

[0071] Obtain the standard weight value ZB per meter of this type of cable, and then obtain the length value LL of the two spaced double roller mechanisms 2; calculate the standard weight value ZXB of the cable using the formula ZXB=ZB*LL;

[0072] Step 4: Compare the obtained segment difference value CQYi with the segment difference range;

[0073] If the coil segment difference CQYi is greater than the coil segment difference range, it indicates that the weight of that section of cable is too heavy, and a signal indicating that the cable section is too heavy is generated.

[0074] If the coil segment difference CQYi is within the coil segment difference range, it means that the weight of the coil segment of cable is qualified and the generated cable segment is qualified.

[0075] If the coil segment difference CQYi is less than the coil segment difference range, it indicates that the weight of that section of cable in the wound coil is too light, and a signal indicating that the weight of that section of cable is too light is generated.

[0076] When a signal indicating that the cable segment is heavier or lighter is received, the abnormal cable segment is marked using coordinates (x, y); where x represents the number of turns of the cable on the turntable, and y represents the specific cable segment area within that turn.

[0077] The application of the weighing system for the double-roller turntable of this invention obtains real-time cable weighing data and performs real-time calculation and analysis on the weighing data to obtain the cable weight data, and achieves real-time online monitoring of the turntable during the winding process, avoiding overload when the turntable is wrapped, which may cause the turntable to malfunction.

[0078] Then, by analyzing the measurement data obtained by the weighing sensor 3, each loop is analyzed as a whole. When a fault is detected, the cable of that loop is analyzed segment by segment to determine which specific area has a quality problem. Therefore, the application of this weighing system can quickly and accurately mark the area where the fault occurs, making it easy to find the fault after winding.

[0079] The working principle of the present invention: The weighing system for the double-roller turntable of the present invention has the advantage of saving space by setting two rollers 22 structure compared with the single-roller weighing system; however, the setting of the weighing sensor 3 in the weighing system requires the existing double-roller turntable to rotate during the weighing process, which leads to the problem of inconvenient wiring of the weighing sensor 3.

[0080] The application of the weighing system for the double-roller turntable of this invention obtains real-time cable weighing data and performs real-time calculation and analysis on the weighing data to obtain the cable weight data, and achieves real-time online monitoring of the turntable during the winding process, avoiding overload when the turntable is wrapped, which may cause the turntable to malfunction.

[0081] Then, by analyzing the measurement data obtained by the weighing sensor 3, each loop is analyzed as a whole. When a fault is detected, the cable of that loop is analyzed segment by segment to determine which specific area has a quality problem. Therefore, the application of this weighing system can quickly and accurately mark the area where the fault occurs, making it easy to find the fault after winding.

[0082] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
