Description

Technical Field

[0001] The invention belongs to the technical field of cigarette monitoring, and in particular relates to a cigarette paper auxiliary material consumption calculation device and method. Background Art

[0002] With the digital transformation and development of cigarette manufacturing enterprises, digital control of all production links is required. In the cigarette production stage, it is necessary to accurately calculate the consumption of cigarette paper and the output of cigarettes, so as to optimize the preparation of cigarette auxiliary materials and the calculation method of output consumption. In the current cigarette manufacturing field, there is no effective and accurate method to calculate the consumption of cigarette paper auxiliary materials. The approximate auxiliary material consumption can only be calculated by the approximate number of cigarette paper rolls consumed (4000-6000 meters per roll). For example, production is carried out according to three shifts, A, B, and C, every day. The three shifts use a total of 35 rolls of cigarette paper every day. The auxiliary material planner manually counts the number of cigarette paper rolls consumed by the unit on that day, and uses this as the basis for calculating the auxiliary material consumption on that day. This calculation method cannot effectively calculate the residual auxiliary materials on the cigarette machine. Therefore, the current calculation of cigarette paper consumption has the following defects:

[0003] (1) The existing consumption calculation of cigarette paper auxiliary materials mainly relies on the statistics of material planners, which is relatively cumbersome and complicated. It needs to be counted and calculated for each unit, which consumes manpower.

[0004] (2) The method for calculating the consumption of cigarette paper auxiliary materials can only roughly calculate the consumption of cigarette paper auxiliary materials of a unit on a given day. It cannot accurately calculate the consumption of each shift and cannot implement consumption statistics according to the shift, which is not conducive to the calculation of overall output, quality and consumption.

[0005] (3) The consumption calculation method for cigarette paper auxiliary materials can only count and summarize the auxiliary material consumption table for each unit, but cannot implement the viewing of consumption data, which is not conducive to the management of production ingredients, etc. Summary of the invention

[0006] The purpose of the present invention is to provide a device and method for calculating the consumption of cigarette paper auxiliary materials, which can determine whether the cigarette paper is in use by collecting paper break detection signals, and determine the cigarette paper conveying length by using the cloth pulley high-speed pulse sensor signal, thereby obtaining cigarette paper consumption data, which can be calculated accurately to cm units, so as to solve the problem that the consumption of cigarette paper auxiliary materials cannot be accurately calculated and cannot be accounted for according to production shifts.

[0039] 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.

[0040] like Figure 1 and Figure 2 As shown, the present application provides a cigarette paper auxiliary material consumption calculation device, including a tipping paper consumption calculation device and a cigarette paper consumption calculation device.

[0041] The tipping paper consumption calculation device of the present application includes a paper supply roller 9, a first metal sheet 11, a first metal sensor 14, an L-shaped bracket 12, a second metal sensor 17, a paper pressing roller 10 and a first photoelectric sensor 18. The first metal sheet 11 is a metal strip, which is directly welded to the paper supply roller 9 to ensure the synchronization of the two. The first metal sheet 11 of the present application is welded to the side wall near the end of the paper supply roller 9. Such a setting can ensure that the input of the tipping paper 13 is not hindered and is not within the range of the tipping paper to avoid affecting or damaging the tipping paper.

[0042] The first metal sensor 14 is fixed on the L-shaped bracket 12, and the L-shaped bracket 12 is fixed on the back plate of the cigarette making machine. The first metal sensor 14 cooperates with the first metal sheet 11 to capture the pulse signal generated by the paper feeding roller. In order to ensure the accuracy of signal capture, the distance between the end of the first metal sensor 14 and the first metal sheet 11 is 2mm. When the paper pressing roller and the paper feeding roller rotate synchronously, the tipping paper is pressed for transportation. Every time the tipping paper feeding roller rotates one circle, the first metal sensor is triggered by the first metal sheet once, generating a high-level signal. At the same time, the first metal sensor transmits the high-level signal to the PLC controller 15 for processing.

[0043] In the present application, the second metal sensor 17 is arranged on the back plate of the cigarette making machine and cooperates with the paper pressing roller 10 to detect whether the paper pressing roller 10 is in the working position. The first photoelectric sensor 18 is arranged at the front end position where the tipping paper enters the paper feeding roller.

[0044] The first photoelectric sensor is arranged at the front end position where the tipping paper enters the paper feeding roller, and is used for detecting the tipping paper.

[0045] In the present application, the cigarette paper consumption measuring device includes a second metal sheet 2, a cloth belt wheel 1, a third metal sensor 3, a tensioning wheel 4, a lower guide roller 5, a left guide roller 6, a right guide roller 7 and a second photoelectric sensor 8. The cloth belt wheel 1 is installed on the cigarette making machine, and the second metal sheet 2 is an arc-shaped metal sheet, which occupies one-third of the arc of the outer circle of the cloth belt wheel. The second metal sheet 2 is installed on the outer circle of the cloth belt wheel 1, and the third metal sensor 3 is installed on the base of the cigarette making machine. The end of the third metal sensor 3 corresponds to the cloth belt wheel 1, and the distance between the end of the third metal sensor 3 and the cloth belt wheel 1 is 3-5mm. The tensioning wheel 4, the lower guide roller 5, the left guide roller 6 and the right guide roller 7 are all arranged on the cigarette making machine above the cloth belt wheel side, the tensioning wheel is arranged between the lower guide roller and the cloth belt wheel, the lower guide roller is arranged at the lower right of the left guide roller, the lower guide roller, the left guide roller and the right guide roller are used to support the cloth belt to rotate counterclockwise, and the second photoelectric sensor is installed on the base of the cigarette making machine at the lower right of the right guide roller.

[0046] In the present application, the first metal sensor 14 , the second metal sensor 17 , the first photoelectric sensor 18 , the third metal sensor 3 and the second photoelectric sensor 8 are all electrically connected to the PLC controller 15 , and the PLC controller 15 is electrically connected to the industrial computer 16 .

[0047] In the present application, the first metal sensor, the second metal sensor and the third metal sensor are all high-frequency metal sensors.

[0048] In the present application, a touch screen is included, and the touch screen is connected to the PLC controller and the industrial control electromechanical signal respectively.

[0049] 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 industrial computer 16 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, allowing the user to input parameters such as the diameter Ф of the tipping paper feed roller and the shift setting, and can also provide additional functions such as historical data query and abnormal consumption alarm prompt.

[0050] 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.

[0051] The PLC controller communicates with the touch screen via RS485. The touch screen can set the "fabric pulley diameter benchmark" according to the cloth pulley size of different units. The touch screen can display the real-time "cigarette paper consumption" data of the shift, and has corresponding "start" and "reset" buttons for calibrating the cloth pulley diameter and manually clearing the consumption data of cigarette paper auxiliary materials. The PLC controller interacts with the industrial computer in real time through the network cable, transmits auxiliary material consumption to the industrial computer, and the industrial computer calibrates the system time of the touch screen and PLC controller in real time.

[0053] S1, press the start button to determine whether the cigarette paper auxiliary material consumption calculation device is in the start state, if so, proceed to step S2;

[0054] S2, determine whether tipping paper and cigarette paper are detected, if yes, proceed to step S3. Specifically, in step S2, if tipping paper is detected, the following steps are adopted:

[0055] S21, judging whether the paper pressing wheel is pressed down, if so, proceeding to step S22;

[0056] S22, determine whether the paper feed roller pulse is detected, if so, add 1 to the first pulse counter.

[0057] When cigarette paper is detected, it is determined whether a cloth belt wheel pulse is detected. If a cloth belt wheel pulse is detected, the second pulse counter is incremented by 1.

[0058] S3, the first pulse counter and the second pulse counter are increased by 1 respectively;

[0059] S4, reading the diameter of the paper supply roller and the diameter of the cloth belt wheel respectively;
