Description

Technical Field

[0001] The present invention relates to a tipping paper hemming detection device and method for a super-high-speed cigarette making machine, belonging to the technical field of quality detection of cigarette-making equipment. Background Art

[0002] Both the PROTOS-M5 cigarette making machine and the PROTOS-M8 cigarette making machine are composed of a VE (tobacco forming machine), an SE (cigarette rod forming machine), and a MAX (filter rod assembling machine). In the filter rod assembling machine, tipping paper is used to wrap the filter rod and assemble the filter rod to the end of the cigarette rod. However, during the assembling production process, due to factors such as uneven force on the material and incomplete coincidence of the positions between the coils, the tipping paper will be offset during the splicing process. The offset tipping paper will be subjected to a lateral force exerted by a side stop when passing through the positioning device, which is likely to cause the hemming of the tipping paper, ultimately resulting in quality defects in the filter rod, and further affecting the subsequent processes of the cigarette.

[0003] Currently, in order to prevent the cigarette with the tipped paper hemmed from flowing into the subsequent processes, the existing technology is to install two fiber optic sensors above the edge of the tipping paper, and the output signal borrows the input point of the glue sensor near its installation position. After determining that it is hemmed through the detection data, the hemmed cigarette is removed by the rubbing and splicing drum removal mechanism, so as to realize the removal and alarm shutdown functions of the cigarette making machine. However, this method is likely to cause confusion between the two alarms of cigarette hemming and glue failure, and for the overall offset of the tipping paper without hemming, it will cause a large number of misremovals, resulting in a large number of normal cigarettes being removed, ultimately reducing the production yield rate and increasing the production cost of the enterprise. Summary of the Invention

[0004] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a tipping paper hemming detection device and method for a super-high-speed cigarette making machine, which can effectively prevent the misremoval of cigarettes caused by the overall offset of the tipping paper, etc., thereby accurately detecting the hemming of the tipping paper, ensuring the production yield rate of cigarettes, and reducing the production cost of the enterprise.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is: a tipping paper hemming detection device for a super-high-speed cigarette making machine, including a laser width measuring sensor, a mounting bracket, a rotary encoder, a data processing device, an operation display unit, a photoelectric coupler I, a photoelectric coupler II, and a photoelectric coupler III;

[0006] A tipping paper width detection point is provided between the tipping paper positioning device and the auxiliary conveying roller of the filter rod assembling machine. The laser width measuring sensor is fixed directly above the tipping paper width detection point through the mounting bracket, and the detection direction of the laser width measuring sensor is vertically directed towards the tipping paper width detection point, for real-time detecting the width value of the tipping paper passing through the tipping paper width detection point and feeding it back to the data processing device;

[0007] The rotary encoder is installed on one of the active tipping paper conveying rollers to record the number of rotations of the active tipping paper conveying roller and feed back pulse signals to the data processing device;

[0008] The data processing device is placed in the electric control box of the filter rod making and tipping machine. The data processing device is electrically connected to the operation signal sending port, the alarm shutdown receiving port, and the tipping drum rejection mechanism of the ultra-high-speed cigarette making machine control system through optoelectronic coupler 1, optoelectronic coupler 2, and optoelectronic coupler 3 respectively. The data processing device is used to receive the real-time tipping paper width value fed back by the laser width measuring sensor and the operation signal fed back by the operation signal sending port, and transmit them to the operation display unit for real-time display. At the same time, compare this value with the stored tipping paper hemming rejection threshold value. According to the comparison result, start to receive the pulse signal fed back by the rotary encoder, and then send a control signal to make the tipping drum rejection mechanism perform the rejection operation on the cigarettes, and send a signal to the alarm shutdown receiving port.

[0009] Further, the data processing device is a PLC controller.

[0010] Further, the operation display unit is a touch display screen.

[0011] A working method of the tipping paper hemming detection device of an ultra-high-speed cigarette making machine, the specific steps are as follows:

[0012] A. First, set a marking point on the tipping paper, run the ultra-high-speed cigarette making machine at a low speed to start transporting the tipping paper. When the marking point reaches the tipping paper width detection point, the data processing device controls the rotary encoder to start counting the number of rotations of the active tipping paper conveying roller where it is located until the marking point reaches the tipping drum rejection mechanism and then stops counting. At this time, the counted value is N, and store this value in the data processing device;

[0013] B. According to the specified width of the tipping paper used in actual production, determine that the template tipping paper width is equal to the tipping paper specified width minus 0.1 mm, and then make a template tipping paper. Place the template tipping paper at the tipping paper width detection point, measure the width of the template tipping paper through the laser width measuring sensor, and use this measured value as the tipping paper hemming rejection threshold value, and feed it back to the data processing device for storage, thus completing the initial data setting process of the tipping paper hemming detection device;

[0014] C. After the ultra-high-speed cigarette making machine starts to work normally, when the data processing device receives the high-level operation signal fed back by the operation signal sending port and the rotary encoder feeds back the number of rotations of the active tipping paper conveying roller, determine that the tipping paper hemming detection signal is valid, and the laser width measuring sensor starts to continuously detect the tipping paper passing through the tipping paper width detection point;

[0015] D. The data processing device displays the feedback real-time tipping paper width value through the operation display unit, and at the same time compares this real-time value with the tipping paper hemming rejection threshold value;

[0016] If the real-time value exceeds the tipping paper hemming rejection threshold value, it indicates that the tipping paper has not been hemmed, and the normal operation of the super-high-speed cigarette making machine is maintained;

[0017] If the real-time value does not exceed the tipping paper hemming rejection threshold value, it indicates that the tipping paper has been hemmed. At this time, the data processing device starts to receive the pulse signal feedback from the rotary encoder to count the number of rotations of the tipping paper active conveying roller. When the count value reaches N - 1, the data processing device issues a control signal to make the tipping drum rejection mechanism start to work and continuously reject 5 cigarettes; after completing one rejection operation, it continues to operate normally;

[0018] E. If the continuous rejection time of the tipping drum rejection mechanism in a certain time exceeds 5 seconds, it indicates that the tipping paper hemming is longer. At this time, the data processing device sends a signal to the alarm shutdown receiving port. Then, when the super-high-speed cigarette making machine control system receives this signal, the equipment stops, and at the same time, the fault information is displayed through the operation display unit.

[0019] Compared with the existing fiber optic sensor edge detection technology, the present invention combines a laser width measuring sensor, a rotary encoder, a data processing device, and an operation display unit. First, the rejection threshold value is set, and then the width value of the tipping paper is collected by the laser width measuring sensor, and the two are compared. If the width value does not exceed the rejection threshold value, it indicates that the tipping paper at the current tipping paper width detection point has been hemmed. Then, according to the counting method of the rotary encoder, it is determined that the tipping paper with hemming reaches the tipping drum rejection mechanism. At this time, the tipping drum rejection mechanism is controlled to reject the cigarettes made from the tipping paper with hemming, so as to ensure the subsequent processes of the cigarettes; in addition, if the continuous rejection work of the tipping drum rejection mechanism lasts for more than 5 seconds at a time, it indicates that the length of the tipping paper hemming is longer. At this time, the super-high-speed cigarette making machine control system receives the signal sent by the data processing device, stops the equipment, and at the same time, the fault information is displayed through the operation display unit. Therefore, the present invention uses the original equipment of the super-high-speed cigarette making machine, only needs to add a few devices, can accurately detect the situation of the tipping paper hemming, and perform corresponding rejection work; and because it detects the width of the tipping paper, it can effectively prevent the mis-rejection of cigarettes caused by phenomena such as the overall deviation of the tipping paper, ensure the production yield of cigarettes, and reduce the production cost of enterprises.

At this time, the counted value is N (thereby determining the transport distance between the tipping paper width detection point 4 and the tipping drum rejection mechanism 6), and store this value in the data processing device;

[0033] B. According to the specified width of the tipping paper 7 used in actual production, determine that the template tipping paper width is equal to the tipping paper specified width minus 0.1 mm, and then make a template tipping paper; place the template tipping paper at the tipping paper width detection point 4, measure the width of the template tipping paper through the laser width measuring sensor 1, and use this measured value as the tipping paper hemming rejection threshold value, and feedback it to the data processing device for storage, thereby completing the initial data setting process of the tipping paper hemming detection device;
