Problems solved by technology

[0004] The above patent documents disclose different meter counting devices, and they all have a common deficiency: the twisted cables are all directly contacted with the drive wheel connected with the meter counter, and the meter counter is driven to measure, and the meter is measured by applying pressure. Clamp the cable to reduce the meter counting error, the final meter counting accuracy is not ideal, and the excessive pressure is applied, which will easily cause the cable to be flattened, deformed and damaged

Embodiment 1

[0019] Such as figure 1 with figure 2 As shown, the device of this embodiment includes two wheels (1), two wheels (2) and a meter counter (3). The cable to be measured first passes through the gap between the two wheels (1) to eliminate The vertical jitter generated when the cable travels, and then the cable passes through the gap between the two wheels (2), eliminating the horizontal jitter generated when the cable travels, and the cable is pulled out to drive the meter counter Count the meters.

[0020] In this embodiment, two wheel rollers (1) are used at the wire inlet end, which can ensure that the vertical direction jitter of the cable can be eliminated regardless of whether the wire is fed from the upper end or the lower end of the wheel roller (1).

[0021] In this embodiment, the length of the Ф8.16mm steel strand is measured. The measured value is 2500m, and the actual measured value is 2500.5m. Comparing the two data, the error of meter counting is 0.02%.

Embodiment 2

[0023] Such as image 3 with Figure 4 As shown, the device of this embodiment includes four wheels (1), four wheels (2) and a meter counter (3). The cable to be measured first passes through the gap between the two wheels (1) to eliminate The cable jitters in the vertical direction, and then the cable passes through the gap between the two wheels (2), eliminating the cable jitter in the horizontal direction. After the cable is pulled out, the meter counter is driven to count the meters. After the meter counter (3) passes through the gap between the two wheels (2) and the two wheel rollers (1), the jitter of the cable is further eliminated and the meter counting is accurate.

[0024] In this embodiment, the length of the steel-cored aluminum stranded wire with Φ9.0mm is measured. The measured value is 4000m, and the actual measured value is 4000.6m. Comparing the two data, it is found that the meter counting error is 0.015%.

Embodiment 3

[0026] Such as Figure 5 with Image 6 As shown, in this embodiment, the cable to be tested first passes through a member (4) fixed on the bracket. The member (4) has a circular hole (5) with the same diameter as the cable in the direction of the cable travel. After the cable passes through the circular hole (5), the jitter is eliminated, and then the cable clings to the upper surface of the meter counter (3), and the friction force drives the meter counter to rotate for meter counting. The cable pull-out end is set at the same position The symmetrical member (4) with round holes (5) at the inlet end can eliminate jitter at the inlet and outlet ends of the cable, and ensure the accuracy of meter counting to the greatest extent.

[0027] In this embodiment, the length of the steel-cored aluminum stranded wire of Φ9.0mm is measured. The measured value is 3000m, and the actual measured value is 3000.7m. The two data are compared, and the meter counting error is 0.023%.

Abstract

The invention discloses a method for reducing error of a meter counter by eliminating jitter of a cable and aims at providing a method which can reduce the error of the meter counter. The method is realized by the following technical proposals: the meter counter is fixed between a wire stranding device and a wire winding machine, the cable penetrates a hole or a seam with slight bigger diameter before the measurement of the cable, and the measurement is further carried out by the meter counter after eliminating the jitter of the cable. In order to lead the cable to pass through the meter counter more smoothly and further reduce the error of the meter counter, the method can lead the cable to penetrate the hole or the seam with the slight bigger diameter after the measurement for further eliminating the jitter of the cable, thereby improving the precision of the meter counter of the cable. The method can effectively eliminate the jitter of the cable and lead the cable to drive the meter counter to measure under the smooth state, thereby greatly reducing the error of the meter counter; and the contrast of data measured by the method with the data obtained by actual measurement obtains the result that average error of the meter counter by utilizing the method for measurement is not more than plus or minus 0.02 percent.

Description

Technical field [0001] The invention relates to a length measurement method, and more particularly to a method for reducing meter counting errors by eliminating cable jitter during meter counting. Background technique [0002] In the production of cables, the wires are drawn according to a certain size and specifications, and then sent to the stranding machine to be stranded, and then wound on the wire reel. The finished product is obtained by dividing the reel. The cable metering device is usually set in the stranding machine. Between the equipment and the take-up reel, because the measurement is performed at high speed, there is an error in the cable meter counting process. The size of the error is directly related to the manufacturer’s benefit, reputation and user’s economic benefits. Try to minimize the cable meter The error has a very realistic and positive meaning. [0003] Various types of meter counting devices that have been reported and used at present usually use the fo...
