Description

Technical Field

[0001] The invention belongs to the technical field of automatic monitoring of cigarette production, and in particular relates to a device and method for automatically calculating consumption of tipping paper auxiliary materials. Background Art

[0002] In the cigarette production process, tipping paper is a key packaging material, and accurate monitoring of its consumption is crucial for material management and cost control. The existing tipping paper auxiliary material consumption is mainly counted and calculated by material planners, and the calculation basis is the number of tipping paper rolls consumed by the unit each month (4,500 meters per roll) divided by the unit's output in that month.

[0003] Currently, cigarette equipment calculates the consumption of tipping paper on a monthly basis based on output and the number of rolls of tipping paper consumed. It cannot calculate the consumption of tipping paper on a daily basis or by production shift, and cannot meet the monitoring needs of modern cigarette production lines. Summary of the invention

[0004] The purpose of the present invention is to provide a device and method for automatically calculating the consumption of tipping paper auxiliary materials. By installing paper feed roller pulse detection, metal sensor, PLC and human-machine interface, automatic and accurate calculation of tipping paper consumption can be achieved to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

[0006] An automatic measuring device for tipping paper auxiliary material consumption includes a paper feed roller pulse detection device fixedly arranged on the tipping paper feed roller;

[0007] A first metal sensor, the first metal sensor is fixed on an L-shaped bracket, the L-shaped bracket is fixed on the back plate of the device, and the first metal sensor is used to capture the pulse signal generated by the paper feed roller pulse detection;

[0008] a second metal sensor, the second metal sensor being matched with the paper pressing roller;

[0009] The photoelectric switch is arranged at the front end position where the tipping paper enters the tipping paper feeding roller, and is used to detect the tipping paper;

[0011] Furthermore, the paper feed roller pulse detection is a metal strip welded on the tipping paper feed roller.

[0012] Furthermore, the first metal sensor is a high-frequency metal sensor.

[0013] Furthermore, the distance between the tip of the first metal sensor and the paper feed roller pulse detection is 2 mm.

[0014] Furthermore, the host computer includes a touch screen or a computer interface.

[0017] S2, if there is paper on the tipping paper feed roller, determine whether the paper pressing roller is pressed down, if so, proceed to step S3;

[0018] S3, judging whether the tipping paper feed roller pulse is detected, if so, the pulse counter is incremented by 1;

[0019] S4, reading the tipping paper feed roller diameter reference, and calculating the tipping paper consumption;

[0020] S5. Read the system time and shift time. If the system time = shift time, reset the rising edge steps S1 to S4 until the system time = shift time. The output signal controls the pulse counter to zero and the process ends.

[0021] Furthermore, in step S4, the calculation formula for the consumption of tipping paper is:

[0022] L = n × π × Ф, where n is the total number of pulses and Ф is the diameter of the tipping paper feed roller.

[0023] Furthermore, in step S5, during the reset rising edge process from step S1 to step S4, if the system time is ≠ the shift change time, the pulse counters are not cleared.

[0033] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0034] like Figure 1 and Figure 2 As shown, the present application provides an automatic measuring device for tipping paper auxiliary materials, including a paper feed roller pulse detection 3, which is fixed on the tipping paper feed roller 1. The paper feed roller pulse detection 3 of the present application is a metal strip, which is directly welded on the tipping paper feed roller 1 and is tightly fixed with the tipping paper feed roller 1 to ensure that the two rotate synchronously. The paper feed roller pulse detection 3 of the present application is welded on the side wall of the tipping paper feed roller 1 near the end. Such a setting can ensure that the input of the tipping paper 5 is not hindered and is not within the range of the tipping paper 5 to avoid affecting or damaging the tipping paper.

[0035] In the present application, the first metal sensor 6 is fixed on the L-shaped bracket 4, and the L-shaped bracket 4 is fixed on the back plate of the device. The first metal sensor 6 is used to capture the pulse signal generated by the paper feed roller pulse detection 3. In order to ensure the accuracy of signal capture, the distance between the end of the first metal sensor and the paper feed roller pulse detection is 2mm. When the pressing roller 2 and the tipping paper feed roller 1 rotate synchronously, the tipping paper 5 is pressed for transportation. Every time the tipping paper feed roller 1 rotates one circle, the first metal sensor 6 is triggered once by the paper feed roller pulse detection 3 to generate a high-level signal. At the same time, the first metal sensor 6 transmits the high-level signal to the PLC controller 7 for processing.

[0036] The present application also includes a second metal sensor 9, which cooperates with the paper pressing roller 2 to detect whether the paper pressing roller is in the working position. A photoelectric switch 10 is arranged at the front end position where the tipping paper enters the tipping paper feeding roller 1 to detect the tipping paper.

[0037] The first metal sensor 6, the second metal sensor 9 and the photoelectric switch 10 are all connected to the PLC controller 7 by electrical signals, and the PLC controller 7 is connected to the host computer 8 by electrical signals. The PLC controller of the present application is the core of the entire measurement system, and is responsible for receiving and processing the pulse signal transmitted by the metal sensor. The host computer 8 adopts a touch screen or a computer interface to provide an intuitive and easy-to-use operation interface. The interface displays the consumption of tipping paper calculated by the PLC, and allows the user to input parameters such as the diameter Ф of the tipping paper feed roller and the shift setting. At the same time, it can provide additional functions such as historical data query and abnormal consumption alarm prompt.

[0038] The PLC has a preset algorithm program that can calculate the actual consumption of tipping paper based on the total number of pulses n received and the diameter Ф of the tipping paper feed roller input by the user, using the formula "consumption = n × π × Ф", and send the information to the host computer for display based on shift settings, abnormal consumption alarms, etc.

[0039] At the same time, the consumption of equipment's kraft paper can be collected in real time through Ethernet. If there is any abnormality, the equipment management personnel can intervene in time to effectively reduce material consumption.

[0040] like Figure 3 As shown, the present application also provides a method for automatically calculating the consumption of tipping paper auxiliary materials, using any of the above-mentioned automatic calculation devices for the consumption of tipping paper auxiliary materials, and adopting the following steps:

[0041] S1. The tipping paper feed roller is started, and the photoelectric switch detects whether there is paper on the tipping paper feed roller. If no tipping paper is detected, the process returns to determining whether the tipping paper feed roller is started.

[0042] S2. If there is paper on the tipping paper feed roller, determine whether the paper pressing roller is pressed down. If so, go to step S3, if not, end.

[0043] S3. Determine whether the tipping paper feed roller pulse is detected. If so, add 1 to the pulse counter. Otherwise, end.

[0044] S4. Read the tipping paper feed roller diameter reference and calculate the tipping paper consumption. The calculation formula of the tipping paper consumption L is:

[0045] L = n × π × Ф, where n is the total number of pulses and Ф is the diameter of the tipping paper feed roller.

[0046] S5. Read the system time and shift time. If the system time = shift time, reset the rising edge steps S1 to S4 until the system time = shift time. The output signal controls the pulse counter to zero and the process ends.

[0047] The judgment of the first system time = shift time in step S5 is to determine whether to calculate the tipping paper consumption L by shift. Of course, in other embodiments of the present application, it can also be calculated by day by modifying the shift time to day.

[0048] The next system time=shift time in step S5 means that when the system time is not equal to the shift time, steps S1 to S4 are repeated and the pulse counter is incremented by 1 each time until the system time=shift time is reached.

[0049] In step S5, during the reset rising edge step S1 to step S4, if the system time ≠ shift time, the pulse counter will not be cleared. This means that when the equipment fails and stops, if the counter is cleared, the total amount of tipping paper consumption cannot be accurately obtained.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
