Description

Technical Field

[0001] The invention relates to the technical field of comprehensive cigarette testing, and more specifically, to an automatic comparison method for instrument differences and brand differences of a filter rod comprehensive testing bench. Background Art

[0002] Cigarette filter rods are one of the important components of cigarettes. The fluctuation of their physical indicators will directly affect the quality of cigarettes. The cigarette filter rod comprehensive test bench is a special instrument for measuring the physical indicators of filter rods. It uses a sampling tube to sample and analyze the filter rods at the outlet of the forming machine every 12-13 seconds, and displays the results of various physical indicators such as filter rod weight, suction resistance, circumference, roundness, length, etc. on the screen, so that machine operators and filter rod in-process inspectors can timely grasp the quality of filter rods and make corresponding adjustments to the fluctuation of filter rod quality.

[0003] In the actual production process, the filter rod forming workshop usually has two types of comprehensive test benches: online testers and offline testers. The KC offline comprehensive test bench is the benchmark instrument, and the physical indicators of the filter rods measured are standard values. The online comprehensive test bench is responsible for real-time detection of the physical indicators of the filter rods produced by each machine. The forming machine operator dynamically adjusts the equipment and operating parameters by observing the fluctuations of the physical indicators of the filter rods measured by the online comprehensive test bench, thereby controlling the physical indicators of the filter rods within the workshop's internal control range. However, in reality, there is usually an instrument gap between the machine's online comprehensive test bench and the KC offline comprehensive test bench. After the filter rods are produced, there will be a gap in the detection indicators due to inconsistent curing time. The existence of the gap will cause the online comprehensive test bench and the KC offline comprehensive test bench to obtain different physical indicator results when testing the same batch of filter rods, misleading the operator to adjust the equipment and operating parameters, thereby producing unqualified filter rods.

[0004] Therefore, there is an urgent need for an automatic comparison method for the instrument gap and brand gap of a filter rod comprehensive test bench. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic comparison method for the instrument gap and brand gap of a filter rod comprehensive test bench to solve the problems in the above-mentioned prior art, and to calibrate the instrument gap and brand gap of the comprehensive test bench, thereby ensuring that there is no detection gap regardless of manual detection or automatic detection.

[0012] After the measurement is completed, using the offline comprehensive test bench as a reference instrument, comparing the difference between the first measurement result and the second measurement result to obtain a first difference;

[0013] The first difference is used as the instrument bias value and input into the online comprehensive test bench to complete the instrument gap calibration.

[0014] The automatic comparison method of the instrument gap and brand gap of the filter rod comprehensive test bench as described above, wherein preferably, the brand gap calibration specifically includes:

[0015] During the normal production process of the molding machine, the online comprehensive test bench uses a sampling unit to sample the newly produced filter rods, measure the various physical indicators of the filter rods, and retain the third measurement results;

[0028] At present, the calibration method of the integrated test bench mainly uses a standard calibration rod for manual calibration. After calibration, the comparison result is the instrument gap. This method calibrates the instrument gap by inputting the deviation of the results of the same batch of cured filter rods measured on the KC offline integrated test bench and the online integrated test bench into the online integrated test bench to ensure that the KC offline integrated test bench is used as the benchmark, and the test data of other online detection instruments is consistent with that of the KC offline integrated test bench. The disadvantage of this calibration method is that it can only calibrate the instrument gap during manual comparison, but cannot calibrate the gap before and after curing, that is, the brand gap.

[0029] like Figure 1 As shown, the automatic comparison method of the instrument gap and brand gap of the filter rod comprehensive test bench provided in this embodiment specifically includes:

[0030] Step S1, instrument gap calibration: use the offline comprehensive test bench and the online comprehensive test bench to measure the physical indicators of the filter rod sample after complete curing, and according to the difference between the two measurement results, use the offline comprehensive test bench as the reference instrument to calibrate the instrument gap of the online comprehensive test bench.

[0031] In one embodiment of the method for automatically comparing instrument differences and brand differences of a filter rod comprehensive test bench of the present invention, step S1 may specifically include:

[0032] Step S11, taking a filter rod sample after complete solidification and measuring various physical indicators of the filter rod on an offline comprehensive testing bench, and retaining the first measurement result.

[0033] Step S12: Take the same sample to the online comprehensive test bench to measure various physical indicators of the filter rod, and retain the second measurement result.

[0034] Step S13: After the measurement is completed, the offline comprehensive test bench is used as a reference instrument to compare the difference between the first measurement result and the second measurement result to obtain a first difference.

[0035] Step S14: taking the first difference as the instrument bias value and inputting it into the online comprehensive test bench to complete the instrument gap calibration.

[0036] Step S2, brand gap calibration: During the normal production process of the molding machine, the physical indicators of the newly produced filter rods are measured using the online comprehensive test bench, and the physical indicators of these samples are measured using the offline comprehensive test bench in multiple time periods. Based on the difference in the measurement results corresponding to the online comprehensive test bench and the offline comprehensive test bench, the brand gap calibration is performed on the online comprehensive test bench using the offline comprehensive test bench as the reference instrument.

[0037] In one embodiment of the method for automatically comparing instrument differences and brand differences of the filter rod comprehensive test bench of the present invention, the step S2 may specifically include:

[0038] Step S21: During the normal production process of the molding machine, the online comprehensive test bench uses a sampling unit to sample the filter rods just produced, measures various physical indicators of the filter rods, and retains the third measurement result.

[0039] Step S22: Take out the sampled samples, divide them into multiple time periods, use an offline comprehensive test bench to measure various physical indicators of these samples, retain multiple measurement results, and take the average as the fourth measurement result.

[0040] Specifically, there are five time periods, namely: taking it to the offline integrated test bench for measurement immediately after the online integrated test bench measurement, taking it to the online integrated test bench and the offline integrated test bench for measurement after one hour, two hours, six hours, and twenty-four hours of curing respectively.

[0041] Step S23: using the offline integrated test bench as a reference instrument, comparing the difference between the fourth measurement result corresponding to the offline integrated test bench and the third measurement result corresponding to the online integrated test bench to obtain a second difference.

[0042] Step S24: input the second difference as the brand deviation into the online comprehensive test bench to complete brand gap calibration.

[0043] The automatic comparison method between the instrument gap and the brand gap of the filter rod comprehensive test bench provided in the embodiment of the present invention uses the offline comprehensive test bench as a reference instrument to calibrate the instrument gap and the brand gap of the online comprehensive test bench respectively, so as to realize the automatic comparison between the instrument gap and the brand gap, and avoid misleading the operator to adjust the equipment and operating parameters due to the existence of the instrument gap and the brand gap, thereby producing unqualified filter rods.
