Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette manufacturing equipment, and in particular relates to a method for correcting equipment parameters. Background Art

[0002] The tobacco density at the end of the cigarette is one of the important factors affecting the physical and chemical indicators and sensory quality of cigarettes. Both domestic and imported cigarette making machines carry out multi-dimensional inspections on the ends of cigarettes from physical to visual. According to the process flow, the cigarette making machine can detect the tobacco density at the ends of cigarettes at three workstations. The first workstation uses an ultra-precision microwave end density detector, the second workstation uses a photoelectric empty end detector, and the third workstation uses a visual detector for the ends of cigarettes.

[0003] However, when a short end appears at the end of a cigarette, it is impossible to know the root cause of the short end. Summary of the invention

[0009] In some embodiments, the root cause of empty cigarettes is determined based on the cigarette status and the data combination relationship, including: if the cigarette status is normal, and the first set value is normal, the first real-time value is normal, the second set value is normal, the second real-time value is normal, the third set value is abnormal, and the third real-time value is normal, then it is determined that the root cause of empty cigarettes is an abnormal setting of the visual detector at the cigarette end; if the cigarette status is normal, and the first set value is normal, the first real-time value is normal, the second set value is normal, the second real-time value is normal, the third set value is normal, and the third real-time value is abnormal, then it is determined that the root cause of empty cigarettes is a failure of the visual detector at the cigarette end.

[0010] In some embodiments, the root cause of the empty cigarettes is determined based on the cigarette status and the data combination relationship, including: if the cigarette is truly empty, and the first real-time value, the second real-time value, and the third real-time value are all abnormal, determining that the root cause of the empty cigarette is a malfunction of the suction belt and the weight control actuator.

[0030] The root cause of the empty cigarettes is determined based on the cigarette status and the data combination relationship, including: if the cigarettes are truly empty, and the first real-time value, the second real-time value, and the third real-time value are all abnormal, determining that the root cause of the empty cigarettes is a malfunction of the suction belt and the weight control actuator.

[0031] The root cause of cigarette shorts is determined based on cigarette status and data combination relationship, including: if the cigarette is truly short, and only the second real-time value and the third real-time value are abnormal, determining that the root cause of the cigarette shorts is a mechanical failure from the SE microwave back end to the MAX short detection.

[0032] Determining the root cause of the empty cigarette according to the cigarette status and the data combination relationship includes: if the cigarette is truly empty and only the third real-time value is abnormal, determining that the root cause of the empty cigarette is a failure of a component between the MAX empty detection and the end visual detection, as shown in the determination table.

[0033]

[0034] As can be seen from the above table, cases 1 to 7 are conclusions obtained when the cigarette is normal, that is, the empty head of the cigarette is a false empty head, which is caused by a component failure or an incorrect setting of the set value. Cases 8 to 10 are conclusions obtained when the cigarette is truly empty, and the three detectors are finally confirmed to be normal, and the reasons for the vacuum head of the cigarette are obtained. Therefore, through the technical means involved in the present disclosure, the root cause of the empty head of the cigarette can be accurately determined.

[0035] Case 1: The three set values ​​and the corresponding real-time values ​​are all normal, the cigarette is normal, and the three detectors are normal.

[0036] Case 2: Only the setting value of the ultra-precision microwave end density detector is abnormal, and the cigarette is normal, then it is determined that the setting value of the ultra-precision microwave end density detector is set incorrectly.

[0037] Case 3: Only the real-time value of the ultra-precision microwave end density detector is abnormal, and the cigarette is normal, then it is determined that the hardware of the ultra-precision microwave end density detector is faulty.

[0038] Case 4: Only the setting value of the photoelectric empty cigarette detector is abnormal, and the cigarettes are normal. It is determined that the setting value of the photoelectric empty cigarette detector is set incorrectly.

[0039] Case 5: Only the real-time value of the photoelectric short-end detector is abnormal, while the cigarettes are normal. This indicates that the hardware of the photoelectric short-end detector is faulty.

[0040] Case 6: If only the setting value of the visual detector at the end of the cigarette is abnormal and the cigarette is normal, it is determined that the setting value of the visual detector at the end of the cigarette is abnormal.

[0041] Case 7: If only the real-time value of the visual detector at the cigarette end is abnormal and the cigarette is normal, it is determined that the hardware of the visual detector at the cigarette end is faulty.

[0042] Case 8: There is a real empty end in the cigarette, all three detectors are normal, and the real-time values ​​of the three detectors are abnormal, then it is determined that the suction ribbon and weight control actuator are faulty.

[0043] Case 9: There are real short ends in the cigarette, and only the real-time values ​​of the photoelectric short end detector and the visual detector at the end of the cigarette are abnormal. This indicates that there is a mechanical failure from the back end of the SE microwave to the MAX short end detection, such as the cigarette cutting in two, the turning drum, etc.

[0044] Case 10: There is a real empty end in the cigarette, and only the real-time value of the visual detector at the end of the cigarette is abnormal. It is determined that the component between the MAX empty end detection and the end visual detection is faulty.

[0045] It should be noted that the normal range of the setting value of the ultra-precision microwave end density detector is 290~300. When the real-time value is lower than 270, it is judged to be abnormal.

[0046] The normal setting range of the photoelectric cigarette empty detector is 1.7~2.0. When the real-time value is lower than 1.5, it is judged to be abnormal.

[0047] The normal range of the setting value of the cigarette end visual detector is 80%~95%. When the real-time value is lower than 75%, it is judged to be abnormal.

[0048] This technical means can determine the root cause of short cigarettes.
