Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to a method and system for controlling the operation of tobacco leaf processing procedures. Background Technology

[0002] In the tobacco processing stage, tobacco packs and stems are processed separately into leaf shreds and stem shreds using an assembly line. These are then blended together in a specific ratio and flavored to produce finished tobacco shreds for cigarette making. The entire tobacco processing process is divided into several major stages depending on the processing task, such as leaf pretreatment, leaf feeding, leaf shred processing, blending, flavoring, and storage / pneumatic conveying. These major stages are typically separated by large-capacity storage tanks. Each major stage is further divided into several sub-stages, usually separated by small-capacity temporary storage tanks and feeding elevators. Each sub-stage can be controlled independently.

[0003] In actual production, the process from the start of "joint start-up" to the stop of "joint shutdown" often relies on field operators sending commands to the central control system. Furthermore, for sub-process segments where processing tasks have been completed, the "stop" operation for each sub-process segment is typically only performed after the completion of the next major process segment. In other words, by the time the last sub-process segment finishes production before stopping the machine, several preceding sub-process segments have already been running idle for a considerable period. Therefore, under the current operating method, the timeliness of stopping sub-process segments cannot be guaranteed, inevitably leading to "ineffective operation" of the equipment, wasted energy, and increased production costs in the tobacco production process. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that sub-processes in existing tobacco leaf processing procedures cannot be stopped in a timely manner upon completion of their processing tasks. This invention provides a method and system for controlling the operation of tobacco leaf processing procedures. The control unit can detect the production parameters of the corresponding sub-process to determine whether the sub-process has completed its processing task, enabling the control unit to promptly stop the sub-process, thereby reducing energy waste and lowering production costs.

[0005] To address the aforementioned technical problems, embodiments of the present invention disclose a method for controlling the operation of a tobacco leaf processing step, the tobacco leaf processing step including a storage tank discharge section, a cutting section, and a drying section, the method comprising:

[0006] Based on the storage space of each processing device in the tobacco leaf processing process, the tobacco leaf processing process is divided into at least two sub-processes; wherein each sub-process includes at least one processing device.

[0007] Obtain material information for the current sub-process and the downstream adjacent sub-process, and compare the two material information. When the two material information are consistent, the current sub-process triggers the "same" instruction.

[0008] The production parameters of the processing device are acquired by the control unit corresponding to each sub-process; each sub-process is equipped with a corresponding control unit so that the stopping action of each sub-process can be controlled by controlling each control unit.

[0009] Determine if the production parameters meet the preset conditions; if so, after extending the preset time for the current sub-process, trigger the "production stop" command; each sub-process has a corresponding preset time to ensure that all materials in the current sub-process are delivered to the next sub-process;

[0010] The current sub-process is being executed according to the "production stop" instruction.

[0011] By employing the above technical solution, the tobacco leaf processing steps are subdivided into corresponding control units. Material information for the current sub-step and its downstream adjacent sub-steps is acquired and compared. The control unit then collects the production parameters of the current sub-step and determines whether these parameters meet preset conditions. When the production parameters meet the preset conditions, a "production stop" command is triggered after a preset time extension, causing the current sub-step to execute the command. This control and operation method solves the problem of sub-steps running idle when there are no processing tasks, thus reducing energy waste and lowering production costs.

[0012] According to another specific embodiment of the present invention, the embodiment of the present invention discloses that the step of obtaining the production parameters of the processing device collected by the control unit corresponding to each sub-process includes:

[0013] When monitoring the discharge section of the storage tank, the production parameters are set to the running status, empty tank signal, and bottom band encoder value.

[0014] When monitoring the shredding section, the production parameters are set to running status, cabinet empty signal, and moisture meter value;

[0015] When monitoring the drying section, the production parameters are set as follows: operating status, cabinet empty signal, bottom encoder value, moisture meter value, electronic scale flow rate and cumulative quantity.

[0016] According to another specific embodiment of the present invention, the step of determining whether production parameters meet preset conditions includes:

[0017] Determine if the running status is "running";

[0018] Determine if the cabinet empty signal is "1";

[0019] Determine if the value of the underband encoder is greater than the preset value;

[0020] Determine if the moisture meter reading is greater than the upper limit; if so, trigger the "material output" signal.

[0021] Determine if the moisture meter reading is below the lower limit.

[0022] Determine if the flow rate of the electronic scale is 0 and if the cumulative amount is greater than the preset cumulative value.

[0023] According to another specific embodiment of the present invention, the material information disclosed includes material production batch number information.

[0024] According to another specific embodiment of the present invention, the preset time is set based on the material conveying distance and conveying speed between each sub-process.

[0025] The present invention also discloses a system for controlling the operation of a tobacco leaf processing step, used to implement the method for controlling the operation of the tobacco leaf processing step mentioned in the above embodiments, comprising:

[0026] The sub-process division module is used to divide the tobacco leaf processing process into at least two sub-processes based on the storage space of each processing device in the tobacco leaf processing process; wherein each sub-process includes at least one processing device.

[0027] The first data acquisition module is used to acquire material information of the current sub-process and the downstream adjacent sub-process, and compare the two material information. When the two material information are consistent, the current sub-process triggers the "same" instruction.

[0028] The second data acquisition module is used to acquire the production parameters of the processing device collected by the control unit corresponding to each sub-process; wherein, each sub-process is equipped with a corresponding control unit so as to control the stopping action of each sub-process by controlling each control unit;

[0029] The judgment module is used to determine whether the production parameters meet the preset conditions; if so, after the current sub-process is extended by the preset time, the "production stop" command is triggered; each sub-process is set with a corresponding preset time to ensure that all materials in the current sub-process are delivered to the next sub-process.

[0030] The production control module is used to execute the current sub-process according to the "production stop" instruction.

[0031] By adopting the above technical solution, a system for controlling the operation of the tobacco leaf processing process is constructed by setting up a sub-process division module, a first data acquisition module, a second data acquisition module, a judgment module, and a production control module. The control and operation system of this invention solves the problem of sub-processes running idle when there are no processing tasks, thereby reducing energy waste and lowering production costs.

The detection device is installed on each processing device and is used to monitor the operating status of the processing device.

[0033] According to another specific embodiment of the present invention, the present invention discloses that the detection device and the control unit are connected by wired or wireless means to enable real-time transmission of production parameters.

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0046] Please see Figure 1 , Figure 1 The diagram shows an overall flow chart of a method for controlling the operation of a tobacco leaf processing step according to an embodiment of the present invention.

[0047] like Figure 1 As shown, an embodiment of the present invention provides a method for controlling the operation of a tobacco leaf processing step. The leaf processing step 300 includes a storage tank discharge section 301, a cutting section 302, and a drying section 303. The method may include steps 101, 102, 103, 104, 105, and 106.

[0048] Step 101: Based on the storage space of each processing device in the tobacco leaf processing process, the tobacco leaf processing process is divided into at least two sub-processes; wherein each sub-process includes at least one processing device;

[0049] Step 102: Obtain the material information of the current sub-process and the downstream adjacent sub-process, and compare the two material information. When the two material information are consistent, the current sub-process triggers the "same" instruction.

[0050] Step 103: Obtain the production parameters of the processing device collected by the control unit corresponding to each sub-process; wherein, each sub-process is set up with a corresponding control unit so as to control the stopping action of each sub-process by controlling each control unit;

[0051] Step 104: Determine whether the production parameters meet the preset conditions;

[0052] Step 105: If yes, after the current sub-process is extended by the preset time, a "production stop" command is triggered; each sub-process has a corresponding preset time to ensure that all materials in the current sub-process are delivered to the next sub-process.

[0053] Step 106: The current sub-process is executed according to the "Production Stop" instruction.

[0054] The applicant has fully considered the problems that arise during the tobacco leaf processing step. By subdividing the tobacco leaf processing steps and their corresponding control units, and by acquiring and comparing material information between the current sub-step and downstream adjacent sub-steps, the applicant uses the control unit to collect production parameters for the current sub-step and determine whether these parameters meet preset conditions. When the production parameters meet the preset conditions, a "production stop" command is triggered after a preset time extension, causing the current sub-step to execute the command. This control and operation method solves the problem of sub-steps running idle when there are no processing tasks, thus reducing energy waste and lowering production costs.

[0055] Furthermore, the step of acquiring the production parameters of the processing device collected by the control unit corresponding to each sub-process includes:

[0056] When monitoring the discharge section 301 of the storage tank, the production parameters include the operating status, the empty tank signal, and the bottom encoder value;

[0057] When monitoring the shredding section 302, production parameters include operating status, cabinet empty signal, and moisture meter reading;

[0058] When monitoring the drying section 303, the production parameters include operating status, cabinet empty signal, bottom encoder value, moisture meter value, electronic scale flow rate and cumulative amount.

[0059] Furthermore, the step of determining whether the production parameters meet the preset conditions includes:

[0060] Determine if the running status is "running";

[0061] Determine if the cabinet empty signal is "1";

[0062] Determine if the value of the underband encoder is greater than the preset value;

[0063] Determine if the moisture meter reading is greater than the upper limit; if so, trigger the "material output" signal.

[0064] Determine if the moisture meter reading is below the lower limit.

[0065] Determine if the flow rate of the electronic scale is 0 and if the cumulative amount is greater than the preset cumulative value.

[0066] In some embodiments, the preset value can be set according to the specific processing device and the total amount of material; the upper limit value and the lower limit value can be set according to the actual production requirements, the upper limit value can be set to 0.8 and the lower limit value can be set to 0.1; the preset cumulative value can be set according to the total amount of material in the current production batch.

[0067] Specifically, the material information includes the material production batch number.

[0068] In practice, the preset time is set based on the material conveying distance and conveying speed between each sub-process.

[0069] In a specific example, the operation of the leaf filament processing step is controlled. During actual production, the material has already passed through this monitored step to ensure precise control of the step's operation and shutdown. For example... Figure 3As shown, the leaf processing step includes a storage tank discharge section 301, a shredding section 302, and a drying section 303. The storage tank discharge section 301 includes a leaf storage tank 3011, a leaf storage tank bottom belt, and a first conveyor belt. A first photoelectric switch is installed inside the leaf storage tank 3011, and a first bottom belt encoder is installed on the leaf storage tank bottom belt. The shredding section 302 includes a first temporary storage tank 3021, a shredder 3022, a first temporary storage tank bottom belt, and a first moisture meter 3023. A second photoelectric switch is installed inside the first temporary storage tank 3021, and a second bottom belt encoder is installed on the first temporary storage tank bottom belt. The drying section includes a second temporary storage tank 3031, a second temporary storage tank bottom belt, an electronic scale 3032, a drying machine 3033, and a second moisture meter 3034. A third photoelectric switch is installed inside the second temporary storage tank 3031, and a third bottom belt encoder is installed on the second temporary storage tank bottom belt.

[0070] When monitoring the discharge section 301 of the storage tank, firstly, the production batch number information of the discharge section 301 and the shredding section 302 is compared. When they match, it indicates that the two sections produced the same batch of tobacco leaves, triggering the "same batch number" signal. Secondly, the control unit corresponding to the current storage tank 3011 collects the operating status of the discharge section 301 and the value of the first bottom band encoder associated with the current storage tank 3011, as well as the empty signal of the first photoelectric switch. When the value of the first bottom band encoder is greater than the preset value and the empty signal is "1", it indicates that the material has been completely discharged from the storage tank 3011, triggering the "material discharged from the tank" signal. Finally, when the discharge section 301 is in "operating", the bottom band of the first temporary storage tank 3021 is in "operating", "same batch number", and "material discharged from the tank", the control unit automatically triggers the "production stop" command after a preset time delay, automatically stopping the processing device in the discharge section 301.

[0071] When monitoring the shredding section 302, firstly, the production batch number information of the shredding section 302 and the drying section 303 is compared. When they match, it indicates that the two sections produced the same batch of tobacco leaves, triggering the "same batch number" signal. Secondly, the control unit corresponding to the first temporary storage cabinet 3021 collects the operating status of the shredding section 302 and the values ​​of the second bottom-band encoder associated with the first temporary storage cabinet 3021, as well as the cabinet empty signal of the second photoelectric switch. When the value of the first bottom-band encoder is greater than the preset value and the cabinet empty signal is "1", it indicates that the material has been completely removed from the first temporary storage cabinet, triggering the "material removed from cabinet" signal. Then, when the shredding section 302 is in "running" and the moisture content after shredding is greater than the upper limit, the "material output from shredding section" signal is set. When the "production start" or "production stop" signal is generated, the signal is reset. Finally, when the shredding section is in "running", the bottom belt of the second temporary storage cabinet 3021 is in "running", the batch number is the same, the material in the cabinet has been exhausted, the shredding section has output material, and the moisture content after shredding is lower than the lower limit, after a preset delay, the control unit automatically triggers the "production stop" command to automatically stop the processing device in the shredding section 302.

[0072] When monitoring the drying section 303, firstly, the production batch number information of the drying section 303 is compared with that of the downstream adjacent process. When the two match, it indicates that the two sections are producing the same batch of tobacco leaves, triggering the "same batch number" signal. Secondly, the cumulative value of the electronic scale is set according to the current production batch of tobacco leaves. When the actual cumulative value passing through the electronic scale 3032 is greater than the preset cumulative value and the flow rate of the electronic scale 3032 is "0", it indicates that the material has passed through the electronic scale 3032, triggering the "electronic scale material completed" signal. Then, the control unit corresponding to the second temporary storage cabinet 3031 collects the operating status of the drying section 303 and the second temporary storage cabinet 3031. The value of the third bottom belt encoder associated with 031 and the cabinet empty signal of the third photoelectric switch are used to determine whether the material has been completely removed from the second temporary storage cabinet 3031. When the value of the third bottom belt encoder is greater than the preset value and the cabinet empty signal is "1", it means that the material has been completely removed from the second temporary storage cabinet 3031, triggering the "material removed from cabinet" signal. Finally, when the drying section 303 is in "running", the rear belt of the drying machine 3033 is in "running", the electronic scale has removed all material, the material removed from the cabinet has been removed, and the moisture content after shredding is lower than the lower limit, the control unit automatically triggers the "production stop" command after a preset delay, automatically stopping the processing device in the drying section 303.

[0073] like Figure 2 As shown, embodiments of the present invention also provide a system for controlling the operation of a tobacco leaf processing step, used to implement the method for controlling the operation of a tobacco leaf processing step provided in the above embodiments, including: a sub-process division module 201, a first data acquisition module 202, a second data acquisition module 203, a judgment module 204, and a production module 205.

When the two material information are consistent, the current sub-process triggers the "same" instruction.

[0076] The second data acquisition module 203 is used to acquire the production parameters of the processing device collected by the control unit corresponding to each sub-process; wherein, each sub-process is provided with a corresponding control unit so as to control the stopping action of each sub-process by controlling each control unit;

[0077] The judgment module 204 is used to determine whether the production parameters meet the preset conditions; if so, after the current sub-process is extended by the preset time, the "production stop" command is triggered; wherein, each sub-process is set with a corresponding preset time to ensure that all materials of the current sub-process are delivered to the next sub-process;

[0078] The production control module 205 is used to execute the current sub-process according to the "production stop" instruction.
