Description

Technical Field

[0001] This invention relates to the field of tobacco technology, and in particular to a microwave foreign matter removal method and system for cigarette making machines. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Foreign matter in cigarettes is a quality defect in the tobacco product manufacturing process, which has a significant impact on the quality and sensory characteristics of cigarettes. Since non-tobacco substances inevitably mix in during the cigarette production process, it is necessary to accurately remove cigarettes containing non-tobacco substances during the cigarette production process.

[0004] Currently, cigarette rolling machines commonly use microwave detection systems for cigarette weight control. The principle is to detect the moisture content of the cigarette stick through a resonant cavity and calculate its density. Theoretically, this detection method is equally effective for detecting non-tobacco substances in the cigarette stick. However, current microwave detection technology does not effectively output and utilize the detection signals for non-tobacco substances, and does not exchange foreign object signals with the main cigarette rolling machine system.

[0005] Secondly, in order to capture foreign object signals, a high-speed processing module must be used. The paper "Design of Online Foreign Object Removal System for Cigarettes Based on Microwave Detection" introduces a signal processing method based on a microcontroller. However, with the continuous increase in the speed of cigarette rolling equipment, this signal processing method can no longer meet the requirements of high-speed signal processing. At the same time, the removal method described in the paper requires the addition of a synchronous removal mechanism, which is not only costly but also no longer feasible on current cigarette rolling machines. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes a microwave foreign object removal method and system for cigarette rolling machines. By marking, synchronizing, transferring, and shifting the foreign object cigarette, the system moves the foreign object cigarette to the removal valve, where it is directly removed using the removal valve built into the rolling machine. This eliminates the need for additional removal ports and improves the accuracy of foreign object cigarette removal.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a microwave foreign object removal method for a roll-to-roll machine, comprising:

[0009] The machine acquires the shaft encoder signal and microwave foreign object signal of the cigarette machine. Based on the number of incremental pulses of the shaft encoder signal corresponding to the detection of the microwave foreign object signal, the machine marks whether the foreign object is located in the front or rear row of the double long cigarettes.

[0010] The dual clock pulse signal and multiple clock pulse signal of the receiving and loading machine are acquired. Based on the shaft encoder signal of the cigarette machine and the dual clock pulse signal of the receiving and loading machine, the pulse rhythm of the two signals is consistent to complete the synchronization and data shifting of the cigarette machine and the receiving and loading machine.

[0011] The single clock pulse signal is obtained from the dual clock pulse signal and multiple clock pulse signals of the receiving and loading machine. The detection data of the cigarette machine's process cycle is obtained and synchronously buffered into the receiving and loading machine's data shift register at the junction of the cigarette machine and the receiving and loading machine. The position of the foreign object marker is synchronously transmitted to the receiving and loading machine's data shift register based on the single clock pulse signal.

[0012] The detection data is buffered and stored in the receiving machine data shift register according to the process cycle of the receiving machine until the foreign object marker position moves to the rejection valve, thereby controlling the start of the rejection valve to remove the foreign object cigarette.

[0013] As an alternative implementation, a double-long cigarette is composed of two single cigarettes arranged one after the other. In the shaft encoder signal, a double-long cigarette corresponds to M pulses, and a single cigarette corresponds to M / 2 pulses. The incremental pulse number is divided by M to determine the number of revolutions of the shaft encoder, thereby locating the double-long cigarette where the foreign object is located. Then, based on the comparison result between the remainder and M / 2, it is determined whether the foreign object is in the front or back row of the double-long cigarette, where M is a positive integer.

[0014] As an alternative implementation, one revolution of the shaft encoder includes 2M incremental pulses; when the remainder is less than or equal to M / 2, the foreign object is located on the front single cigarette of the double long cigarette; otherwise, the foreign object is located on the rear single cigarette of the double long cigarette.

[0015] As an alternative implementation, for every 2N multi-channel clock pulse signals generated, one dual clock pulse signal is generated simultaneously, where N is a positive integer.

[0016] As an alternative implementation method, the pulse number ratio of dual-clock pulse signal, multi-channel clock pulse signal, and single-clock pulse signal is 1:20:2.

[0017] As an alternative implementation, at the cigarette rolling machine, the detection data corresponding to the process cycle of the cigarette rolling machine is acquired and cached in the cigarette rolling machine data shift register to complete the acquisition and shifting of the cigarette rolling machine detection data. When the junction of the cigarette rolling machine and the receiving and loading machine is reached, the detection data in the cigarette rolling machine data shift register is synchronously cached in the receiving and loading machine data shift register. The receiving and loading machine data shift register receives the detection data from the cigarette rolling machine and completes the acquisition and shifting of the receiving and loading machine detection data.

[0018] As an alternative implementation method, the shift is performed by moving the pointer. The data acquisition point changes with the clock pulse beat, and the data is directly filled into the changed pointer buffer. The pointer in the buffer is automatically incremented by 1 at the rising edge of each dual clock pulse signal, that is, it moves one position to the right. Then, new data is filled into the new data acquisition point, and the pointer moves in a circular cycle.

[0019] Secondly, the present invention provides a microwave foreign object removal system for a roll-to-roll machine, comprising:

[0020] The marking module is configured to acquire the shaft encoder signal and microwave foreign object signal of the cigarette machine, and mark the foreign object as being in the front or rear row of the double long cigarettes based on the number of incremental pulses of the shaft encoder signal corresponding to the detection of the microwave foreign object signal.

[0021] The acquisition module is configured to acquire the dual clock pulse signal and multiple clock pulse signal of the receiving machine. Based on the shaft encoder signal of the cigarette machine and the dual clock pulse signal of the receiving machine, the two signal pulse beats are consistent to complete the synchronization and data shifting of the cigarette machine and the receiving machine.

[0022] The synchronization module is configured to obtain a single clock pulse signal based on the dual clock pulse signal and multiple clock pulse signals of the receiving and loading machine, acquire the detection data of the cigarette machine's process cycle, and synchronously buffer it in the receiving and loading machine's data shift register at the junction of the cigarette machine and the receiving and loading machine. It also synchronizes the position of the foreign object marker to the receiving and loading machine's data shift register based on the single clock pulse signal.

[0023] The rejection module is configured to cache detection data into the receiving machine data shift register according to the receiving machine process cycle, until the foreign object marker position moves to the rejection valve, thereby controlling the start of the rejection valve to reject the foreign object cigarette.

[0024] Thirdly, the present invention provides an electronic device including a memory and a processor, and computer instructions stored in the memory and running on the processor, wherein the computer instructions, when executed by the processor, perform the method described in the first aspect.

[0025] Fourthly, the present invention provides a computer-readable storage medium for storing computer instructions, which, when executed by a processor, perform the method described in the first aspect.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention proposes a microwave foreign object removal method and system for cigarette making and sealing machines. It calculates incremental pulse signals and indication signals using shaft encoder signals, and employs microwave detection technology to collect microwave foreign object signals, thus marking foreign cigarettes. Data synchronization between the cigarette making machine and the sealing machine is achieved through dual-clock pulse signals and multi-channel clock pulse signals for synchronous removal of foreign cigarettes. Simultaneously, data transfer and shifting are completed through data shift registers in both the cigarette making and sealing machines until the foreign cigarette moves to the removal valve. The removal is then performed directly using the built-in removal valve of the cigarette making and sealing machine, eliminating the need for additional removal ports. This achieves real-time displacement and removal of cigarettes during production, improving the accuracy of foreign cigarette removal and expanding the foreign object removal function of the cigarette making machine.

[0039] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0040] Example 1

[0041] This embodiment provides a microwave foreign object removal method for a roll splicing machine, such as... Figure 1 As shown, it includes:

[0042] The machine acquires the shaft encoder signal and microwave foreign object signal of the cigarette machine. Based on the number of incremental pulses of the shaft encoder signal corresponding to the detection of the microwave foreign object signal, the machine marks whether the foreign object is located in the front or rear row of the double long cigarettes.

[0043] The dual clock pulse signal (DCP pulse signal) and multi-channel clock pulse signal (MCP signal) of the receiving and loading machine are acquired. Based on the shaft encoder signal of the cigarette machine and the dual clock pulse signal of the receiving and loading machine, the pulse rhythm of the two signals is consistent to complete the synchronization and data shifting of the cigarette machine and the receiving and loading machine.

[0044] The single clock pulse signal is obtained from the dual clock pulse signal and multiple clock pulse signals of the receiving and loading machine. The detection data of the cigarette machine's process cycle is obtained and synchronously buffered into the receiving and loading machine's data shift register at the junction of the cigarette machine and the receiving and loading machine. The position of the foreign object marker is synchronously transmitted to the receiving and loading machine's data shift register based on the single clock pulse signal.

[0045] The detection data is buffered and stored in the receiving machine data shift register according to the process cycle of the receiving machine until the foreign object marker position moves to the rejection valve, thereby controlling the start of the rejection valve to remove the foreign object cigarette.

[0046] In this embodiment, the oversampling module (EL1262 module) based on Beckhoff motion control system realizes real-time acquisition of high-speed signals. The signal processing speed is better than that of the processors currently used. The SE axis encoder signal, TEWS microwave foreign object signal, dual clock pulse signal (DCP pulse signal) and multi-channel clock pulse signal (MCP pulse signal) are acquired through the digital input module. The rejection valve is controlled through the digital output module.

[0047] The digital input module uses an EL1262 module with 8 digital input points to connect the SE axis encoder signal, TEWS microwave foreign object signal, dual clock pulse signal (DCP pulse signal), and multi-channel clock pulse signal (MCP pulse signal) to the acquisition module; the digital output module uses an EL2262 module with 8 digital input output points to realize the control signal output of the rejection valve.

[0048] TEWS microwaves determine the density of tobacco by detecting the moisture content of the tobacco sticks. The density of non-tobacco substances (including but not limited to metals, rubber, plastics, cotton and linen fibers, nylon, etc.) in tobacco sticks differs significantly from the density of the tobacco sticks themselves. In theory, TEWS microwave detection has the ability to detect foreign objects in tobacco. In this embodiment, TEWS microwaves are used to monitor changes in the moisture density of the tobacco sticks, extract abnormal density signals, and identify non-tobacco substances.

[0049] As an alternative implementation method, the microwave detection system used includes, but is not limited to, the TEWS MW3011 / MW3012 series.

[0050] In this embodiment, as Figure 2 The diagram shows the correspondence between the shaft encoder signal and the cigarette. Based on the shaft encoder signal, the number of incremental pulses for each cigarette is calculated. A double-long cigarette (i.e., a double-long cigarette composed of two single cigarettes arranged one after the other) requires 128 pulses. One revolution of the shaft encoder = 2 * double-long cigarettes = 256 incremental pulses = one indicator pulse. Therefore, each single cigarette = 64 incremental pulses. In a double-long cigarette, the first 64 incremental pulses correspond to the front row of cigarettes, and the last 64 incremental pulses correspond to the back row of cigarettes. The front and back rows of cigarettes can be determined by calculating the number of incremental pulses.

[0051] Therefore, the distinction between the front and rear rows of cigarettes containing foreign objects is achieved by using microwave foreign object signals and the incremental pulse count of the cigarette. The specific implementation process is as follows: Figure 3As shown, when a microwave foreign object signal is detected, the number of incremental pulses of the shaft encoder at the corresponding moment is determined. Then, according to the relationship that "one rotation of the shaft encoder = 2 * two long cigarettes = 256 incremental pulses = one indicator pulse", the number of incremental pulses is divided by 128 to determine the number of rotations of the shaft encoder, and then the location of the foreign object in the two long cigarettes is determined. Based on the remaining number of incremental pulses (less than half a rotation, the number of pulses in the cigarette where the foreign object is located = the number of incremental pulses), based on the above relationship, it is determined whether the foreign object is in the front or back row of the two long cigarettes.

[0052] In this embodiment, by acquiring the shaft encoder pulse signal and dual-clock pulse signal of the cigarette rolling machine, and based on the complete consistency of the pulse beats (cycles) of the shaft encoder pulse signal of the cigarette rolling machine and the dual-clock pulse signal of the loading machine, the synchronization and data shifting and transmission of the equipment between the cigarette rolling machine and the loading machine are completed. For data shifting and handover, see [link to relevant documentation]. Figure 6 In general, the SE data shift and MAX data shift are synchronized. Each position of the equipment has a defined workstation, and the data is output as soon as it reaches the fixed position of the valve.

[0053] Based on the above, the relationship between the cigarette machine and the assembly machine can be derived by taking one double-long cigarette as the benchmark. The relationship is based on the relationship between the cigarette machine and the assembly machine. The relationship is based on the relationship between the cigarette machine and the assembly machine. The relationship between the two machines can be derived by taking one double-long cigarette as the benchmark. The cigarette machine and the assembly machine can then be used for synchronous calculation.

[0054] According to the production process of cigarette rolling equipment, the tobacco strips are cut into single, long, filterless cigarettes. These single cigarettes are then split in half, separated, fitted with filters, wrapped, and cut into individual finished cigarettes. The single cigarettes are the basic production pulse provided by the cigarette rolling equipment. The cigarette rolling machine operates on a linear motion; the tobacco is drawn into long strips by negative pressure and cut into individual single cigarettes by a cutting motor. The machine is equipped with a shaft encoder, which generates pulse signals whenever it runs automatically. The single cigarettes produced by the machine enter the receiving machine. After being cut into individual single cigarettes, the linear motion is changed from lateral to longitudinal by a spider-hand mechanism. The single cigarettes are passed one by one on the drum of the receiving machine. A timing disc is installed behind the drum. During machine operation, each single cigarette moving from one slot to another generates a DCP pulse. For every double-length cigarette produced by the cigarette rolling machine, the receiving machine also delivers one double-length cigarette, so the two are synchronized, and the corresponding pulses can be obtained through the shaft encoder and the timing disk.

[0055] For cigarette rolling equipment, the equipment length and the length of the double-length cigarettes are fixed. Each station on the machine body from rolling to cigarette outlet is fixed. The microwave position and the rejection valve position are fixed, meaning the number of double-length cigarettes from the microwave to the rejection valve is fixed. A data shift register with a length greater than N is designed. The data starting point is defined as buffer array 0, where an initial value variable is inserted. The buffer is a data group structure, and the array internally defines a single cigarette data structure variable, defining all production condition data and quality inspection data contained in a single cigarette. Referring to the cigarette rolling machine production control process, the software is designed to internally define different insertion point positions. The microwave data insertion point is 45, meaning the foreign object cigarette signal insertion point is 45. A moving pointer is used; the foreign object cigarette data buffer pointer changes with the clock pulse, incrementing by 1 on each rising edge of the DCP until the data output point, i.e., when it shifts to the sampling gate cigarette bar, the data insertion point at the sampling gate cigarette bar is 86. The significance of this data handover is that foreign cigarette samples can be taken at the sampling gate, and the rejection valve will not remove the foreign cigarette after sampling.

[0056] The single clock pulse signal for a single cigarette is calculated based on the dual clock pulse signal and multiple clock pulse signals of the receiving machine. The receiving machine's data shift register shifts in accordance with the clock pulse signal. In order to correctly start the rejection valve to remove foreign cigarettes at the rejection valve data output point, the receiving machine's data shift register needs to shift the number of slots from the sampling gate to the rejection valve by 179 (for external discharge, the number of slots increases by 1), that is, 86+179=265, and the rejection valve data insertion point is 265.

[0057] The single-clock pulse signal is a clock pulse for a single cigarette. Combined with incremental pulses, it marks the front and rear rows of cigarettes containing foreign objects. This distinction is then made in the data shift register of the receiving machine for removal. The single-clock pulse signal equals 10 * multiple clock pulse signals. These multiple clock pulse signals affect the removal time and position of a single cigarette, as well as the start and hold times of the removal valve. All these factors influence the correct removal of foreign cigarettes.

[0058] Understandably, the above descriptions such as microwave data insertion point 45, data insertion point 86 at the sampling gate smoke bar, number of slots from the sampling gate to the rejection valve 179, and rejection valve data insertion point 265 are all examples based on standard models and are not representative. Each device has its own unique characteristics. Of course, the above parameters can also be set and controlled on the host computer interface.

[0059] In this embodiment, the single clock pulse signal of a single cigarette is calculated based on the dual clock pulse signal and multiple clock pulse signals of the receiving machine, in order to be used for subsequent synchronization and shift calculations.

[0060] Specifically:

[0061] The timer dial causes the proximity switch to generate an MCP pulse signal. One rotation of the timer dial equals 20 MCP pulse signals, which is equivalent to one double-long cigarette. The proximity switch generates a DCP pulse signal. One rotation of the timer dial equals one DCP pulse signal, which is equivalent to one double-long cigarette.

[0062] The SCP pulse signal is calculated from the DCP pulse signal and the MCP pulse signal; 1 double-long cigarette = 1 DCP pulse signal = 2 SCP pulse signals = 20 MCP pulse signals.

[0063] Therefore, by using the above relationships, the rising and falling edges of the DCP, MCP, and SCP pulse signals can be calculated for synchronization and shift calculations.

[0064] In this embodiment, data synchronization between the cigarette making machine and the receiving machine is achieved based on synchronization pulse signals (i.e., dual clock pulse signals and multi-channel clock pulse signals). By constructing a data shift register for the cigarette making machine and a data shift register for the receiving machine, data handover and shifting for each process cycle are completed, thereby achieving synchronous removal of foreign cigarettes.

[0065] Based on the production process of the cigarette making machine, the cigarette production process from tobacco shredding to the cigarette outlet is taken as a main line. A data shift register is designed for the main line. According to the cycle pulse of cigarette production, the data shift register is driven to move sequentially. Equipment detection data and process data are located at different data acquisition points on the main line. Relevant data is collected and written to the buffer at each pulse beat.

[0066] For the auxiliary materials in cigarette production, including cigarette paper, filter tip, and tipping paper, three branch lines are designed. Similarly, three branch line data shift registers are designed. According to the input situation, the data shifts with the pulse beat and finally inserts the relevant auxiliary material data at the data intersection point and merges into the main line's data shift register.

[0067] According to the equipment operation logic, the cigarette making machine is divided into two parts: the cigarette making machine and the receiving and loading machine. Therefore, there are two main data shift registers: the cigarette making machine data shift register and the receiving and loading machine data shift register. According to the process cycle of the cigarette making machine, the detection data of the corresponding process cycle is obtained and cached in the cigarette making machine data shift register, thus completing the data acquisition and shifting of the cigarette making machine part. When the handover point between the cigarette making machine and the receiving and loading machine is reached, the data of the cigarette making machine part is synchronously cached in the receiving and loading machine data shift register. The receiving and loading machine data shift register receives the data of the cigarette making machine part and completes the acquisition and shifting of the receiving and loading machine data.

[0068] like Figure 4 As shown, when data moves to a certain point, it enters other data shift registers, completing the data exchange. Figure 5As shown, a moving pointer method is used, where the data insertion (acquisition) point changes with the clock pulse. Data is directly filled into the changed pointer buffer to achieve data exchange. The pointer of the data buffer is automatically incremented by 1 at the rising edge of each DCP pulse signal, that is, it moves forward by one bit. Then, new data is filled into the new data acquisition point. The buffer pointer moves in a circular cycle, and the data output point acquires the data output from the buffer area at the new pointer position.

[0069] like Figure 6 As shown, when the insertion of a foreign object signal collected at the microwave location is offset to the sampling gate cigarette bar, the data displacement register of the cigarette machine outputs to the data displacement register of the receiving machine to complete the synchronization between the two. Then, according to the process cycle of the receiving machine, the detection data is buffered into the receiving machine data shift register until it is offset to the insertion point of the rejection valve, thereby controlling the start of the rejection valve to remove the foreign object cigarette.

[0070] In addition, this embodiment can also complete data interaction with the human-computer interaction system, including parameter setting, rejection quantity statistics, etc., and the human-computer interaction system displays and feeds back real-time data such as foreign object cigarette rejection statistics.

[0074] The acquisition module is configured to acquire the dual clock pulse signal and multiple clock pulse signal of the receiving machine.

The data acquisition point changes with the clock pulse beat. The data is directly filled into the changed pointer buffer. The pointer in the buffer is automatically incremented by 1 at the rising edge of each dual clock pulse signal, that is, it moves one position to the right. Then, new data is filled into the new data acquisition point. The pointer moves in a circular loop.

6. A microwave foreign object removal system for a coil splicing machine, characterized in that, include: The marking module is configured to acquire the shaft encoder signal and microwave foreign object signal of the cigarette machine, and mark the foreign object as being in the front or rear row of the double long cigarettes based on the number of incremental pulses of the shaft encoder signal corresponding to the detection of the microwave foreign object signal. The acquisition module is configured to acquire the dual clock pulse signal and multiple clock pulse signal of the receiving machine. Based on the shaft encoder signal of the cigarette machine and the dual clock pulse signal of the receiving machine, the two signal pulse beats are consistent to complete the synchronization and data shifting of the cigarette machine and the receiving machine. The synchronization module is configured to obtain a single clock pulse signal based on the dual clock pulse signal and multiple clock pulse signals of the receiving and loading machine, acquire the detection data of the cigarette machine's process cycle, and synchronously buffer it in the receiving and loading machine's data shift register at the junction of the cigarette machine and the receiving and loading machine. It also synchronizes the position of the foreign object marker to the receiving and loading machine's data shift register based on the single clock pulse signal. The rejection module is configured to cache detection data into the receiving machine data shift register according to the receiving machine process cycle until the foreign object marker position moves to the rejection valve, thereby controlling the start of the rejection valve to reject the foreign object cigarette. A double-long cigarette is composed of two single cigarettes arranged one after the other. In the shaft encoder signal, a double-long cigarette corresponds to M pulses, and a single cigarette corresponds to M / 2 pulses. Dividing the incremental pulse number by M determines the number of revolutions the shaft encoder has made, thereby locating the double-long cigarette where the foreign object is located. Then, based on the comparison result between the remainder and M / 2, it is determined whether the foreign object is in the front or back row of the double-long cigarette. M is a positive integer. One revolution of the shaft encoder includes 2M incremental pulses; when the remainder is less than or equal to M / 2, the foreign object is on the front single cigarette of the double long cigarette; otherwise, the foreign object is on the rear single cigarette of the double long cigarette.
