Description

Technical Field

[0001] This invention relates to the field of tobacco production technology, and in particular to a method, apparatus, equipment and medium for batch switching control of materials in a tobacco production line. Background Technology

[0002] Material batch switching is necessary during tobacco production, and the mixing of different batches can easily occur during this process, affecting product quality. Therefore, precise control of material batch switching is crucial. Existing technologies often employ a rigid section control method centered on key processing units such as dryers and rehumidifiers. These units are bundled with upstream and downstream conveying, metering, and feeding equipment into a fixed control unit for unified start-up and shutdown. During material batch switching, cleaning and preparation for the next batch can only begin after all equipment within each control unit has been emptied and shut down. Because it is difficult for each control unit to accurately determine the material emptying status in real time, material batch switching operations can only be performed using conservative strategies such as extending emptying time and adding fixed delays to reduce the probability of mixing problems. This approach not only fails to fundamentally eliminate the safety hazards of mixing but also wastes time, leading to a decrease in the overall efficiency of material batch switching in the tobacco production line. Summary of the Invention

[0003] This invention provides a method, apparatus, equipment, and medium for controlling material batch switching in a tobacco production line, in order to solve the problem of low efficiency in material batch switching in tobacco production lines.

A material handling device is configured between the third and fourth storage units in the plurality of first storage units. The material handling device includes at least a material processing device and a material metering device. The third and fourth storage units are adjacent first storage units in the plurality of first storage units along the production sequence of the tobacco production line. The second storage unit is used to receive and output the first material. The first material is the material obtained after being processed by the material handling device corresponding to the second storage unit. The material handling device corresponding to the second storage unit is the material handling device between the fifth storage unit and the second storage unit in the tobacco production line. The fifth storage unit is a first storage unit located upstream of and adjacent to the second storage unit in the tobacco production line. In response to a material batch switching request from the tobacco production line, based on the material level status of at least one second storage unit and the first status of the material handling equipment corresponding to the second storage unit, the material handling equipment corresponding to the second storage unit is controlled to perform a material batch switching operation. The material batch switching operation is used to indicate switching from the first batch of materials to the second batch of materials for material processing. The first status of the material handling equipment corresponding to the second storage unit is used to indicate whether the material handling equipment corresponding to the second storage unit has completed the processing of the first batch of materials.

[0005] According to another aspect of the present invention, a material batch switching control device for a tobacco production line is provided, comprising: A storage unit determination module is used to determine at least one second storage unit from a plurality of first storage units in a tobacco production line. A material handling device is configured between a third storage unit and a fourth storage unit in the plurality of first storage units.

The third storage unit and the fourth storage unit are adjacent first storage units in the plurality of first storage units along the production sequence of the tobacco production line. The second storage unit is used to receive first material and output the first material. The first material is material obtained after being processed by the material handling device corresponding to the second storage unit. The material handling device corresponding to the second storage unit is the material handling device between a fifth storage unit and the second storage unit in the tobacco production line. The fifth storage unit is a first storage unit located upstream and adjacent to the second storage unit on the tobacco production line. The material batch switching module is used to respond to the material batch switching request of the tobacco production line, and control the material processing equipment corresponding to the at least one second storage unit to perform a material batch switching operation based on the material level status of the at least one second storage unit and the first status of the material processing equipment corresponding to the second storage unit. The material batch switching operation is used to indicate switching from the first batch of materials to the second batch of materials for material processing, and the first status of the material processing equipment corresponding to the second storage unit is used to indicate whether the material processing equipment corresponding to the second storage unit has completed the processing of the first batch of materials.

This improves the continuous operation capability and equipment utilization rate of the tobacco production line, thereby enhancing the stability and production efficiency of tobacco production.

[0015] Figure 1 This is a flowchart illustrating a material batch switching control method for a tobacco production line according to an embodiment of the present invention. This embodiment is applicable to situations where batch switching operations are performed on materials processed in a tobacco processing production line. The method can be executed by a material batch switching control device for the tobacco production line, which can be implemented in hardware and / or software. This material batch switching control device can be configured in any electronic device with network communication capabilities. Figure 1 As shown in the figure, a material batch switching control method for a tobacco production line provided by an embodiment of the present invention may include: S110. At least one second storage unit is determined from a plurality of first storage units in the tobacco production line. A material handling device is configured between the third and fourth storage units in the plurality of first storage units. The material handling device includes at least a material processing device and a material metering device. The third and fourth storage units are adjacent first storage units in the plurality of first storage units along the production sequence of the tobacco production line. The second storage unit is used to receive the first material and output the first material. The first material is the material obtained after being processed by the material handling device corresponding to the second storage unit. The material handling device corresponding to the second storage unit is the material handling device between the fifth storage unit and the second storage unit in the tobacco production line. The fifth storage unit is a first storage unit located upstream and adjacent to the second storage unit in the tobacco production line.

[0016] The first storage unit is a device on the tobacco production line used for temporary storage, buffering, or feeding of materials. Material handling equipment exists between two adjacent first storage units along the production sequence of the tobacco production line. For example, the first storage unit can be a feeder, temporary storage cabinet, raw material storage cabinet, or finished tobacco storage cabinet in the tobacco production line. The second storage unit can refer to a storage unit selected from multiple first storage units on the tobacco production line for receiving and outputting the first material. That is, material handling equipment exists upstream of and downstream of the second storage unit in the tobacco production line.

[0017] In this embodiment, the multiple first storage units of the tobacco production line can refer to all equipment used for material storage in the tobacco production line, or it can refer to a portion of the equipment used for material storage in a pre-selected portion of the tobacco production line. The pre-selected equipment used for material storage in the tobacco production line includes at least a starting storage unit, a ending storage unit, and at least one second storage unit. The starting storage unit of the tobacco production line is the storage unit at the beginning of the tobacco production line used for feeding raw materials, and the ending storage unit is the storage unit at the end of the tobacco production line used for storing finished products. For example, the starting storage unit of the tobacco production line can refer to a material preparation cabinet, a stem cabinet, etc., and the ending storage unit of the tobacco production line can refer to a finished product storage cabinet, a stem cabinet, etc.

[0018] Material handling equipment can refer to equipment arranged along the production sequence of a tobacco production line between two adjacent first storage units for processing and metering materials. In this embodiment, the material handling equipment includes at least material processing equipment and material metering equipment. Material processing equipment can refer to equipment that processes materials, such as stem pressing machines, shredders, and drying machines; material metering equipment can refer to equipment that meters and / or controls the flow rate of materials, such as metering belts.

[0019] Based on the storage unit layout of the tobacco production line, at least one second storage unit is determined among the multiple first storage units of the tobacco production line. At the same time, the configuration relationship of material handling equipment between adjacent storage units is clarified, the correspondence between the material handling equipment of the second storage unit and the fifth storage unit upstream of the second storage unit is defined, and the source and physical processing affiliation of the materials received and output by the second storage unit are determined, thereby establishing the corresponding association between the storage unit and the material handling equipment.

[0020] By identifying the second storage unit and clarifying its correspondence with upstream and downstream storage units and material handling equipment, the control boundary of material handling and circulation is clearly defined, providing accurate execution objects and control basis for subsequent material batch switching control.

[0021] S120. In response to a material batch switching request from the tobacco production line, based on the material level status of at least one second storage unit and the first status of the material handling equipment corresponding to the second storage unit, control the material handling equipment corresponding to at least one second storage unit to perform a material batch switching operation. The material batch switching operation is used to indicate switching from the first batch of materials to the second batch of materials for material processing. The first status of the material handling equipment corresponding to the second storage unit is used to indicate whether the material handling equipment corresponding to the second storage unit has completed the processing of the first batch of materials.

[0022] A material batch switching request can refer to an instruction to switch the processing of materials in a tobacco production line from the first batch to the second batch. In response to the material batch switching request, the tobacco production line stops feeding the first batch of materials. Each material handling device in the tobacco production line continues to process the existing first batch of materials. As each material handling device continues to process the first batch of materials, along the production sequence of the tobacco production line, each material handling device completes the processing of all the first batches of materials in the tobacco production line. Optionally, the material batch switching request can be initiated manually, pre-timed, or automatically in response to the initial storage unit of the tobacco production line becoming empty.

[0023] The level status of the second storage unit is used to indicate the material stored in the second storage unit. Optionally, the level status of the second storage unit can be determined by a level gauge built into the second storage unit. The level gauge is an instrument suitable for real-time detection of changes in the material height inside the container.

[0024] The first state of the material handling equipment corresponding to the second storage unit comprises various status information that the material handling equipment corresponding to the second storage unit can use to indicate whether the first batch of material processing has been completed. For example, the first state may include the operating state of the material handling equipment corresponding to the second storage unit and / or the processing state of the material in the material handling equipment corresponding to the second storage unit; wherein, the operating state of the material handling equipment may refer to whether the material handling equipment is running, such as running or dormant, or it may refer to the current processing operation stage of the material handling equipment.

[0025] Upon receiving a material batch switching request from the tobacco production line, based on the material level status of the second storage unit and the first status of the corresponding material handling equipment, it can determine whether the second storage unit and the corresponding material handling equipment have completed the processing of the first batch of materials. This allows the material handling equipment corresponding to the second storage unit, which has completed the processing of the first batch of materials, to perform a material batch switching operation. It also enables the material handling equipment corresponding to the second storage unit to perform preparations for processing the second batch of materials to ensure that it can receive and process the second batch of materials at any time.

[0026] Based on the material level status of the second storage unit and the completion status of the first batch of materials by the corresponding material handling equipment, the processing progress of the first batch of materials by the corresponding material handling equipment can be accurately determined. This ensures that the material handling equipment of the second storage unit can perform material batch switching operations in a timely manner after completing the processing of the first batch of materials, avoiding the blind adoption of conservative and time-consuming control methods such as delaying and waiting, reducing unnecessary waiting time of material handling equipment in the tobacco production line, and thus improving the execution efficiency of material batch switching in the tobacco production line.

[0027] As an optional but not limited implementation, based on the material level of at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, the material handling equipment corresponding to the at least one second storage unit is controlled to perform a material batch switching operation, including: Based on the material level status of at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, a plurality of sixth storage units and the material handling equipment corresponding to the sixth storage units are determined from at least one second storage unit. The plurality of sixth storage units are a plurality of second storage units that are sequentially adjacent to each other in the production sequence of the tobacco production line. The production sequence of the plurality of sixth storage units is located before the second storage units other than the sixth storage units in at least one second storage unit. The material level status of the plurality of sixth storage units is lower than a preset first threshold and the first state of the material handling equipment corresponding to the sixth storage unit meets a preset first condition. The preset first condition is used to indicate the first state of the material handling equipment after completing the first batch of material handling. Material batch switching instructions are sent simultaneously to the material handling devices corresponding to multiple sixth storage units, so that the material handling devices corresponding to multiple sixth storage units can perform material batch switching operations.

[0028] The preset first threshold is a pre-defined upper limit value for the material level status, used to determine whether the material storage inside the second storage unit can instruct the corresponding material handling equipment to perform a material batch switching operation. When the material level status of the second storage unit is lower than the preset first threshold, it indicates that the material storage inside the second storage unit is empty or at an extremely low safety level, meaning that the first batch of materials is not present in the second storage unit.

[0029] The preset first condition is a pre-defined set of material handling equipment status requirements used to determine whether the material handling equipment corresponding to the second storage unit has completed the processing of the first batch of materials. When the first status of the material handling equipment corresponding to the second storage unit meets the preset first condition, it means that the material handling equipment corresponding to the second storage unit has no more first batch of materials being processed.

[0030] When the material level in the second storage unit is lower than the preset first threshold and the first state of the material processing equipment corresponding to the second storage unit meets the preset first condition, and the fifth storage unit adjacent to the second storage unit upstream is determined to have completed all the first batch of material processing, it can be determined that the material processing equipment corresponding to the second storage unit will no longer have the first batch of material input, nor will it have the first batch of material being processed, and there will be no newly generated or yet input first batch of material into the downstream process in the second storage unit. That is, the material processing equipment corresponding to the second storage unit has completed the first batch of material processing, and the material batch switching operation conditions are met.

[0031] If the amount of material to be processed and the amount being processed in the first batch of the tobacco production line is small, or if the tobacco production line has stopped feeding the first batch of material for a period of time before initiating the material batch switching request, then after the material batch switching request is initiated, multiple material handling devices will quickly appear along the production sequence of the tobacco production line to have completed the processing of all the first batch of material. Therefore, based on the material level status of at least one second storage unit and the first state of the material handling device corresponding to the second storage unit, multiple sixth storage units and their corresponding material handling devices can be determined from at least one second storage unit. These multiple sixth storage units are multiple consecutive second storage units whose material level status is below a preset first threshold and whose first state of the corresponding material handling device meets a preset first condition, starting from the initial storage unit of the tobacco production line. Material batch switching instructions are simultaneously sent to the material handling devices corresponding to the determined multiple sixth storage units to cause the material handling devices corresponding to the multiple sixth storage units to perform the material batch switching operation.

[0032] By batch-identifying multiple sixth storage units and their corresponding material processing equipment that meet the conditions for material batch switching operations, centralized and unified control of multiple sets of material processing equipment can be achieved, enabling multiple devices to carry out material batch switching simultaneously, improving the overall execution efficiency of batch switching, and avoiding the cumbersome process and time consumption caused by switching individual devices one by one.

[0033] As an optional but not limited implementation, the first preset condition includes at least the instantaneous material flow rate of the material metering device adjacent to the storage unit along the production sequence of the tobacco production line in the material handling equipment corresponding to the storage unit being zero, and the preset delay processing triggered by the material processing equipment in the material handling equipment corresponding to the storage unit having completed the tail material program or the emptying program. The preset delay processing is used to ensure that all residual materials on the material processing equipment and the material processing equipment outlet conveying equipment are sent to the downstream storage unit.

[0034] When the material handling equipment corresponding to the storage unit is processing material, there will be a continuous flow of material conveyed along the production sequence of the tobacco production line between the material handling equipment corresponding to the storage unit; however, when the material handling equipment corresponding to the storage unit is no longer processing material, the instantaneous material flow rate of the monitored material handling equipment should be 0. The material metering equipment can measure the material, thus accurately obtaining the instantaneous material flow rate. For example, for a metering belt, the weight of the material per unit length can be monitored by the included weighing components, and the belt speed can be monitored by the speed measuring device, thereby allowing the instantaneous material flow rate to be calculated in real time based on the material weight and belt speed.

[0035] The first condition is that the instantaneous material flow rate of the material metering device adjacent to the storage unit along the production sequence of the tobacco production line in the material handling equipment corresponding to the storage unit is zero. This allows the determination, based on the accurate instantaneous material flow rate provided by the material metering device, whether the material handling equipment arranged before the material metering device along the production sequence of the tobacco production line is processing the first batch of materials.

[0036] When the material handling equipment stops feeding the first batch of materials, there is usually still some unprocessed material from the first batch remaining inside. At this point, the equipment will enter either a tailings or emptying procedure. The tailings procedure refers to the final processing operation after feeding stops, where the existing material in the equipment is processed and transported to the downstream process. The emptying procedure refers to the rapid emptying, purging, and other cleaning operations performed after the tailings procedure to ensure no residual material remains. After the material handling equipment corresponding to the storage unit enters the tailings or emptying procedure, a preset delay is automatically triggered. The delay duration can be pre-configured. This preset delay ensures that the material handling equipment corresponding to the storage unit can execute the tailings or emptying procedure for a sufficient duration, ensuring that the first batch of materials is emptied. This reduces the probability of material mixing during batch switching operations, thereby improving the quality of the produced products.

[0037] In this embodiment, the preset delay is triggered by monitoring the material processing equipment entering the tailings or emptying process because some tobacco production lines do not use the emptying process. When only the tailings process is used, the preset delay is triggered when the material processing equipment enters the tailings process. When both the tailings and emptying processes are used, the preset delay is triggered when the material processing equipment enters the emptying process. For example, since frequent execution of the emptying process increases energy consumption and equipment wear, some tobacco production lines do not use the emptying process unless necessary. For small-batch material production, when frequent material batch switching is performed or when the material process parameters between different batches are similar, some tobacco production lines do not use the emptying process unless necessary to ensure production efficiency.

[0038] The preset first condition, by requiring the material processing equipment in the material handling equipment corresponding to the storage unit to complete the tail material program or emptying program, triggers a preset delay process, which can reduce the possibility of residual materials in the material processing equipment, thereby reducing the probability of material mixing during the material batch switching operation. It can also re-verify and ensure that the material handling equipment corresponding to the storage unit no longer has the first batch of materials being processed.

[0039] In this implementation scheme, the first preset condition is achieved by simultaneously requiring the instantaneous material flow of the material metering device adjacent to the storage unit along the production sequence of the tobacco production line in the material handling equipment corresponding to the storage unit to be zero, and the preset delay processing triggered by the material processing equipment in the material handling equipment corresponding to the storage unit having completed the tail material program or emptying program. This provides a precise and executable judgment basis for determining whether the material handling equipment corresponding to the storage unit has completed the first batch of material processing. It can accurately determine the material processing status of the material handling equipment corresponding to the storage unit, thereby providing status support for subsequent material batch switching operations, reducing the risk of mixing of different batches of materials, and avoiding reliance on overly conservative delay strategies, thus reducing unnecessary time waste.

[0040] As an optional but not limited implementation, the method further includes the following steps before simultaneously sending material batch switching instructions to the material handling devices corresponding to multiple sixth storage units: The inlet and outlet conveying devices of the tenth storage unit among the multiple sixth storage units are locked, while the inlet and outlet conveying devices of the sixth storage units other than the tenth storage unit are kept unlocked. The tenth storage unit is the last sixth storage unit in the production sequence along the tobacco production line among the multiple sixth storage units.

[0041] The inlet conveyor is used to transport materials to the storage unit, while the outlet conveyor is used to transport materials from the storage unit to downstream processes. Locking refers to restricting the operation of the conveyor, causing it to stop material transport; unlocking refers to the conveyor remaining in normal operation and capable of performing material transport.

[0042] Before simultaneously sending material batch switching instructions to the material handling equipment corresponding to multiple sixth storage units, the inlet and outlet conveying equipment of the tenth storage unit, which is the last in the production sequence among the multiple sixth storage units, are locked. At the same time, the inlet and outlet conveying equipment of the other sixth storage units (excluding the tenth storage unit) within the multiple sixth storage units are kept in normal operation. This forms a control boundary for material conveying during the material batch switching process with the tenth storage unit as the boundary. Since there is no material in the tenth storage unit and its inlet and outlet conveying equipment are locked, the tenth storage unit is equivalent to an empty isolation area, isolating the multiple sixth storage units from the other second storage units. This effectively prevents the second batch of material from entering the equipment area where the material batch switching operation has not yet been performed, avoiding mixing of different batches of material. It ensures that the sixth storage units can perform the material batch switching operation and are ready to process or immediately process the second batch of material. At the same time, it also ensures the normal processing and emptying of the first batch of material in the other second storage units (excluding the multiple sixth storage units). While ensuring the reliability of batch switching, it maintains the smooth flow of material on the production line.

[0043] Figure 2 This is an example diagram of a tobacco production line structure provided according to an embodiment of the present invention. In this embodiment, the tobacco production line includes multiple storage units, and adjacent storage units along the production sequence of the tobacco production line include material processing equipment and material metering equipment. Figure 2 This is an example of a tobacco production line structure, showing only the case where adjacent storage units include one material processing device and one material metering device. In a real tobacco production line, adjacent storage units can include multiple material processing devices and / or multiple material metering devices. Furthermore, in a real tobacco production line, adjacent storage units may also include one or more storage units between them. See also... Figure 2 Storage unit 201 is the starting storage unit of the tobacco production line. The material supply for the entire tobacco production line is achieved by continuously feeding the raw materials of the tobacco production line into storage unit 201.

[0044] For example, suppose the entire tobacco production line is processing the first batch of materials, and the tobacco production line has stopped feeding the first batch of materials for a period of time before initiating the material batch changeover request, see [link to relevant documentation]. Figure 2If the material level status of storage units 201, 204, and 207 is detected to be below the preset material level status threshold, and it is detected that material processing equipment 202 and 205 have completed the preset delay processing triggered by the tail material program, and the instantaneous material flow rate of material metering equipment 203 and 206 is zero, then it is considered that material processing equipment 202, 205, 203, and 206 all meet the material batch switching operation conditions. At this time, the inlet and outlet conveying devices of storage unit 207 are locked to prevent the subsequent second batch of material from mixing with the first batch of material being processed downstream; the inlet and outlet conveying devices of storage units 201 and 204 remain unlocked, that is, material processing equipment 202, 205, and 206 meet the material batch switching operation conditions. 3. Material metering equipment 206 allows the receipt of a second batch of materials, wherein the inlet conveyor of storage unit 201 remains unlocked, indicating that the second batch of materials can be fed into storage unit 201; since both the inlet and outlet conveyors of storage unit 207 are locked, the production line downstream of storage unit 207 along the production sequence of the tobacco production line can continue to process the remaining first batch of materials, while the material processing equipment 202, material processing equipment 205, material metering equipment 203 and material metering equipment 206 of the upstream production line of storage unit 207 can start to execute the second batch of material processing in response to the initiation of the second batch of material processing work order. Storage unit 207 isolates the production line that processes the first batch of materials and the production line that processes the second batch of materials, thereby avoiding the mixing of different batches of materials and realizing seamless connection between batch switching operation and upstream material conveying.

[0045] The technical solution of this invention, by determining at least one second storage unit from multiple first storage units in a tobacco production line, clarifies the control object and management boundary of material batch switching. Based on the material level status of the second storage unit and the first state of the corresponding material handling equipment, the processing completion status of the first batch of materials by the corresponding material handling equipment can be determined. This avoids relying on conservative and time-consuming control methods such as extending emptying time or adding fixed delays, reducing the risk of material mixing between different batches, ensuring that the material handling equipment can promptly start preparations for processing the next batch of materials, and reducing unnecessary downtime of material handling equipment in the tobacco production line. This improves the execution efficiency of material batch switching in the tobacco production line. Based on the above technical solution, by using the storage unit as the management boundary for material batch switching operations in the tobacco production line, and controlling the material batch switching operations of the material handling equipment in the tobacco production line according to the material level status of the storage unit and the first state of the corresponding material handling equipment, the control logic for material batch switching can be optimized. This improves the continuous operation capability and equipment utilization rate of the tobacco production line, thereby enhancing the stability and production efficiency of tobacco production.

[0046] Figure 3 This is a flowchart of another material batch switching control method for a tobacco production line provided by an embodiment of the present invention. This embodiment further refines the process in the above embodiment of controlling the material processing equipment corresponding to at least one second storage unit to perform a material batch switching operation based on the material level of at least one second storage unit and the first state of the material processing equipment corresponding to the second storage unit. For example... Figure 3 As shown in the figure, another material batch switching control method for a tobacco production line provided by an embodiment of the present invention may include: S310. At least one second storage unit is determined from a plurality of first storage units in the tobacco production line. A material handling device is configured between the third and fourth storage units in the plurality of first storage units. The material handling device includes at least a material processing device and a material metering device. The third and fourth storage units are adjacent first storage units in the plurality of first storage units along the production sequence of the tobacco production line. The second storage unit is used to receive the first material and output the first material. The first material is the material obtained after being processed by the material handling device corresponding to the second storage unit. The material handling device corresponding to the second storage unit is the material handling device between the fifth storage unit and the second storage unit in the tobacco production line. The fifth storage unit is a first storage unit located upstream and adjacent to the second storage unit in the tobacco production line.

Based on the material level of at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, detect the material level state of the seventh storage unit in at least one second storage unit and the first state of the material handling equipment corresponding to the seventh storage unit; the seventh storage unit is the first second storage unit in the production sequence of the tobacco production line in at least one second storage unit; or the seventh storage unit is not the first second storage unit in the production sequence of the tobacco production line in at least one second storage unit, and the material storage equipment corresponding to the eighth storage unit is in operation and has completed the material batch switching operation, the eighth storage unit is the second storage unit in the production sequence of the tobacco production line that is before the seventh storage unit and adjacent to the seventh storage unit.

[0048] Whether the material handling equipment corresponding to the second storage unit has completed the processing of all the first batch of materials depends on whether the first batch of materials remains in the second storage unit, whether the material handling equipment corresponding to the second storage unit is still processing the first batch of materials, and whether there is still any first batch of materials being input into the material handling equipment corresponding to the second storage unit. Therefore, in addition to detecting the material level status of the second storage unit and the first state of the material handling equipment corresponding to the second storage unit, it is also necessary to determine whether the material handling equipment corresponding to the adjacent storage unit upstream of the second storage unit along the production sequence of the tobacco production line has completed the processing of all the first batch of materials, in order to determine whether there is still any first batch of materials being input into the material handling equipment corresponding to the second storage unit. When the adjacent storage unit upstream of the second storage unit is the first second storage unit along the production sequence of the tobacco production line, there is no corresponding material handling equipment for the adjacent storage unit upstream of the second storage unit. Therefore, it is only necessary to determine whether there is still any first batch of materials in the adjacent storage unit upstream of the second storage unit.

[0049] In this embodiment, based on the material level of at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, the material level state of the seventh storage unit and the first state of the material handling equipment corresponding to the seventh storage unit are detected to provide a status basis for subsequent material batch switching. If the seventh storage unit is the first second storage unit in the production sequence of the tobacco production line among at least one second storage unit, then the seventh storage unit does not have an upstream storage unit or a corresponding material handling equipment, so only the material level state of the seventh storage unit needs to be detected. If the seventh storage unit is not the first second storage unit in the production sequence of the tobacco production line among at least one second storage unit, then the seventh storage unit has an upstream adjacent eighth storage unit. To ensure that the processing status of the material handling equipment corresponding to the seventh storage unit for the first batch of materials can be determined by detecting the material level state of the seventh storage unit and the first state of the material handling equipment corresponding to the seventh storage unit, it is necessary to ensure that the material handling equipment corresponding to the eighth storage unit is in operation and has completed the material batch switching operation, that is, the material handling equipment corresponding to the eighth storage unit has completed the processing of all the first batch of materials and will no longer process the first batch of materials and transport them to the material handling equipment corresponding to the seventh storage unit.

[0050] S330. In response to the material level status of the seventh storage unit being lower than a preset first threshold and the first state of the material handling equipment corresponding to the seventh storage unit meeting a preset first condition, a material batch switching instruction is sent to the material handling equipment corresponding to the seventh storage unit to cause the material handling equipment corresponding to the seventh storage unit to perform a material batch switching operation. The process then returns to detecting the material level status of the ninth storage unit in at least one second storage unit and the first state of the material handling equipment corresponding to the ninth storage unit until the material level status of the ninth storage unit is not lower than the preset first threshold and the first state of the material handling equipment corresponding to the ninth storage unit does not meet the preset first condition, or the ninth storage unit is the last second storage unit in the production sequence along the tobacco production line in at least one second storage unit, and the ninth storage unit is the second storage unit in the production sequence along the tobacco production line that is after the seventh storage unit and adjacent to the seventh storage unit.

[0051] When the material level of the seventh storage unit is lower than a preset first threshold and the first state of the material handling equipment corresponding to the seventh storage unit meets a preset first condition, a material batch switching command is sent to the material handling equipment corresponding to the seventh storage unit to enable the material handling equipment corresponding to the seventh storage unit to perform a material batch switching operation. Then, the system continues to monitor the material level of the ninth storage unit, which is located downstream of the seventh storage unit along the production sequence of the tobacco production line, and the first state of the material handling equipment corresponding to the ninth storage unit, until the material level of the ninth storage unit is not lower than the preset first threshold and the first state of the material handling equipment corresponding to the ninth storage unit does not meet the preset first condition, or the ninth storage unit is the last second storage unit in the production sequence of at least one second storage unit along the tobacco production line. Each time the material level of the ninth storage unit is detected to be lower than the preset first threshold and the first state of the material handling equipment corresponding to the ninth storage unit meets the preset first condition, a material batch switching command is sent to the material handling equipment corresponding to the ninth storage unit to enable the material handling equipment corresponding to the ninth storage unit to perform a material batch switching operation.

[0052] Based on the above steps, the material batch switching operation conditions of each second storage unit and its corresponding material handling equipment can be determined one by one according to the production sequence, so as to realize the orderly advancement of material batch switching operation control. By determining that the material batch switching operation conditions of the second storage unit and its corresponding material handling equipment are met, the material handling equipment corresponding to the second storage unit is controlled to perform the material batch switching operation. By cyclically and sequentially checking the subsequent second storage units of the tobacco production line, a progressive material batch switching along the production sequence of the tobacco production line can be realized. This ensures that each second storage unit and its corresponding material handling equipment performs the switching only after all the first batch of material processing has been completed. This can improve the accuracy and continuity of material batch switching control and avoid the risks of invalid switching and material mixing.

[0053] As an optional but not limited implementation, the method further includes the following steps before sending the material batch switching instruction to the material handling device corresponding to the seventh storage unit: In response to the material level status of the seventh storage unit not being lower than a preset first threshold or the first status of the material handling equipment corresponding to the seventh storage unit not meeting the preset first condition, the inlet conveying equipment and outlet conveying equipment of the eighth storage unit are locked. In response to the material level of the seventh storage unit being lower than a preset first threshold and the first state of the material handling equipment corresponding to the seventh storage unit meeting a preset first condition, the lock of the outlet conveying equipment of the eighth storage unit is released, and a material discharge confirmation operation is performed on the seventh storage unit and the material handling equipment corresponding to the seventh storage unit.

[0054] Among them, unlocking refers to restoring the operation control of the conveying equipment, so that the conveying equipment can perform material conveying actions normally; material emptying confirmation operation can refer to the operation of verifying whether the material in the storage unit and the corresponding material handling equipment has been completely emptied.

[0055] When the material level in the seventh storage unit is not lower than a preset first threshold or the first state of the material handling equipment corresponding to the seventh storage unit does not meet a preset first condition, it indicates that the material handling equipment corresponding to the seventh storage unit is still processing the first batch of materials. At this time, the material handling equipment corresponding to the seventh storage unit does not meet the material batch switching condition, and the input of the second batch of materials into the material handling equipment corresponding to the seventh storage unit should be prohibited to avoid mixing of different batches of materials. Therefore, the inlet conveying equipment and outlet conveying equipment of the eighth storage unit adjacent upstream of the seventh storage unit are locked to ensure that the second batch of materials cannot be input into the material handling equipment corresponding to the seventh storage unit.

[0056] Since the material handling equipment corresponding to the adjacent eighth storage unit upstream of the seventh storage unit has completed the material batch switching operation, there will be no more first batch of material input into the material handling equipment corresponding to the seventh storage unit. When the material level of the seventh storage unit is lower than the preset first threshold and the first state of the material handling equipment corresponding to the seventh storage unit meets the preset first condition, it indicates that the material handling equipment corresponding to the seventh storage unit has met the material batch switching condition, allowing the second batch of material to be input into the material handling equipment corresponding to the seventh storage unit. Therefore, the lock of the outlet conveyor of the eighth storage unit is released, indicating that the material handling equipment corresponding to the seventh storage unit can receive the second batch of material; and a material emptying confirmation operation is performed on the seventh storage unit and the material handling equipment corresponding to the seventh storage unit to reconfirm whether the first batch of material exists in the seventh storage unit and the material handling equipment corresponding to the seventh storage unit, further reducing the risk of mixing.

[0057] As an optional but not limited implementation, after the seventh storage unit and the corresponding material handling equipment complete the material emptying confirmation operation, a material batch switching instruction is sent to the corresponding material handling equipment of the seventh storage unit and the locking of the inlet conveying equipment of the eighth storage unit is released.

[0058] After the material emptying confirmation operation is completed in the seventh storage unit and the corresponding material handling equipment, it can be confirmed that there is no longer any material in the first batch in the material handling equipment corresponding to the seventh storage unit and that all materials in the first batch have been processed. At this time, a material batch switching command can be issued to the material handling equipment corresponding to the seventh storage unit. In response to the material batch switching command, the material handling equipment corresponding to the seventh storage unit prepares to process or immediately processes the second batch of materials. At the same time, the lock of the inlet conveyor of the eighth storage unit is released, allowing the second batch of materials to enter the material handling equipment corresponding to the seventh storage unit.

[0059] After confirming the material evacuation, a batch switching command is sent simultaneously, and the inlet conveyor of the upstream storage unit is unlocked. This ensures that there is no residual material in the seventh storage unit and its corresponding equipment before batch switching is performed, reducing the risk of mixing materials from different batches at the source. It also achieves seamless connection between batch switching operation and upstream material conveying, avoiding production interruptions or time waste caused by poor connection between switching operation and material conveying. This ensures the continuity of material flow and the reliability of batch switching on the production line, further improving the overall coordination and execution efficiency of batch switching of materials in the tobacco production line.

[0060] For example, suppose the entire tobacco production line is processing the first batch of materials, see [link to relevant documentation]. Figure 2When a material batch switching request is issued, requesting a switch to the second batch of materials, the feeding of the first batch of materials into storage unit 201 is stopped. The remaining materials in storage unit 201 continue to be conveyed to the downstream production line. When the level gauge built into storage unit 201 detects that the material level in storage unit 201 is lower than the preset level threshold, it is considered that there are no more first batch materials in storage unit 201. The inlet conveying equipment and outlet conveying equipment of storage unit 201 are locked to prevent the second batch of materials to be fed in later from mixing with the first batch of materials being processed downstream. Since storage unit 201 is the first storage unit of the tobacco production line, locking the inlet conveying equipment of storage unit 201 can mean prohibiting the feeding of the second batch of materials into storage unit 201. When it is determined that there is no more material in the first batch in storage unit 201, the instantaneous material flow rate at the material metering device 203 is continuously monitored, and the material level status in storage unit 204 is detected by the level gauge built into storage unit 204. In addition, when material processing equipment 202 enters the tailings process, a preset delay is triggered. When the material level in storage unit 204 is lower than the preset material level threshold, the instantaneous material flow rate at material metering device 203 is zero, and material processing equipment 202 completes the preset delay, it is considered that both material processing equipment 202 and material metering device 203 have completed the processing of all materials in the first batch. At this time, the inlet and outlet conveying devices of storage unit 204 are locked to prevent the subsequent second batch of material from mixing with the downstream material. The first batch of materials being processed is mixed; subsequently, the outlet conveyor of storage unit 201 is unlocked, and a material emptying confirmation operation is performed on material processing equipment 202 and material metering equipment 203, indicating that both equipment have completed processing of the first batch of materials, allowing the second batch to be processed. A further confirmation is made as to whether any first batch material remains in material processing equipment 202 and material metering equipment 203. After the material processing equipment 202 and material metering equipment 203 have completed the material emptying confirmation operation, the inlet conveyor of storage unit 201 is unlocked, allowing the second batch of materials to be fed into storage unit 201, since the outlet conveyor of storage unit 201 has also been unlocked. Therefore, the second batch of materials can be conveyed to the material processing equipment 202 and the material metering equipment 203. Since the inlet and outlet conveying equipment of the storage unit 204 are locked, the production line downstream of the storage unit 204 along the production sequence of the tobacco production line can continue to process the remaining first batch of materials, while the material processing equipment 202 and the material metering equipment 203 of the production line upstream of the storage unit 204 can respond to the start of the second batch of material processing work order and start to execute the second batch of material processing. The storage unit 204 isolates the production line that processes the first batch of materials and the production line that processes the second batch of materials, thereby avoiding the mixing of different batches of materials and realizing seamless connection between batch switching operation and upstream material conveying.Subsequently, the status of material processing equipment 205, material metering equipment 206 and storage unit 207 are checked in sequence to determine whether material processing equipment 205 and material metering equipment 206 are allowed to perform material batch switching operations; the checks are performed sequentially along the production sequence of the tobacco production line until the entire tobacco production line is checked and all material processing equipment and material metering equipment in the entire tobacco production line have completed their material batch switching operations.

[0061] The technical solution of this invention involves detecting the material level status of a seventh storage unit and the first state of the material processing equipment corresponding to the seventh storage unit, based on the material level of at least one second storage unit and the first state of the material processing equipment corresponding to the seventh storage unit. In response to a material level status of the seventh storage unit being lower than a preset first threshold and the first state of the material processing equipment corresponding to the seventh storage unit satisfying a preset first condition, a material batch switching instruction is sent to the material processing equipment corresponding to the seventh storage unit to enable the material processing equipment corresponding to the seventh storage unit to perform a material batch switching operation. The process then returns to detecting the material level status of a ninth storage unit and the first state of the material processing equipment corresponding to the ninth storage unit, until the material level status of the ninth storage unit is not lower than the preset first threshold and the first state of the material processing equipment corresponding to the ninth storage unit does not satisfy the preset first condition, or the ninth storage unit is the last second storage unit in the production sequence along the tobacco production line among the at least one second storage units. Based on the above technical solution, the material batch switching operation conditions of each second storage unit and its corresponding material handling equipment can be determined sequentially according to the production sequence, thus realizing the orderly advancement of material batch switching operation control. By determining that the material batch switching operation conditions of the second storage unit and its corresponding material handling equipment are met, the material handling equipment corresponding to the second storage unit is controlled to perform the material batch switching operation. This process is repeated sequentially to detect subsequent second storage units on the tobacco production line, achieving a step-by-step progressive material batch switching along the production sequence of the tobacco production line. This ensures that each second storage unit and its corresponding material handling equipment only performs the switching after all the first batch of material processing has been completed, improving the accuracy and continuity of material batch switching control and avoiding the risks of invalid switching and material mixing.

[0062] Figure 4 This is a schematic diagram of a material batch switching control device for a tobacco production line according to an embodiment of the present invention. This embodiment is applicable to situations where batch switching operations are performed on materials processed in a tobacco processing production line. The material batch switching control device for the tobacco production line can be implemented in hardware and / or software, and can be configured in any electronic device with network communication capabilities. Figure 4As shown, the material batch switching control device for a tobacco production line provided in this embodiment of the invention may include the following: Storage unit determination module 410 is used to determine at least one second storage unit from a plurality of first storage units in a tobacco production line. A material handling device is configured between the third and fourth storage units in the plurality of first storage units. The material handling device includes at least a material processing device and a material metering device. The third and fourth storage units are respectively adjacent first storage units in the plurality of first storage units along the production sequence of the tobacco production line. The second storage unit is used to receive first material and output the first material. The first material is the material obtained after being processed by the material handling device corresponding to the second storage unit. The material handling device corresponding to the second storage unit is the material handling device between the fifth storage unit and the second storage unit in the tobacco production line. The fifth storage unit is a first storage unit located upstream and adjacent to the second storage unit in the tobacco production line. The material batch switching module 420 is used to respond to the material batch switching request of the tobacco production line, and control the material processing equipment corresponding to the at least one second storage unit to perform a material batch switching operation based on the material level status of the at least one second storage unit and the first status of the material processing equipment corresponding to the second storage unit. The material batch switching operation is used to indicate switching from the first batch of materials to the second batch of materials for material processing, and the first status of the material processing equipment corresponding to the second storage unit is used to indicate whether the material processing equipment corresponding to the second storage unit has completed the processing of the first batch of materials.

[0063] Based on the above embodiments, optionally, according to the material level of the at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, the material handling equipment corresponding to the at least one second storage unit is controlled to perform a material batch switching operation, including: Based on the material level status of the at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, a plurality of sixth storage units and the material handling equipment corresponding to the sixth storage units are determined from the at least one second storage unit. The plurality of sixth storage units are a plurality of second storage units that are sequentially adjacent along the production sequence of the tobacco production line. The production sequence of the plurality of sixth storage units is located before the second storage units other than the sixth storage unit in the at least one second storage unit. The material level status of the plurality of sixth storage units is lower than a preset first threshold and the first state of the material handling equipment corresponding to the sixth storage unit meets a preset first condition. The preset first condition is used to indicate the first state of the material handling equipment after completing the first batch of material processing. Simultaneously send material batch switching instructions to the material handling devices corresponding to the plurality of sixth storage units, so that the material handling devices corresponding to the plurality of sixth storage units can perform material batch switching operations.

[0064] Based on the above embodiments, optionally, according to the material level of the at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, the material handling equipment corresponding to the at least one second storage unit is controlled to perform a material batch switching operation, including: Based on the material level of the at least one second storage unit and the first state of the material handling equipment corresponding to the second storage unit, the material level state of the seventh storage unit in the at least one second storage unit and the first state of the material handling equipment corresponding to the seventh storage unit are detected; the seventh storage unit is the first second storage unit in the production sequence along the tobacco production line among the at least one second storage units; or the seventh storage unit is not the first second storage unit in the production sequence along the tobacco production line among the at least one second storage units, and the material storage equipment corresponding to the eighth storage unit is in operation and has completed the material batch switching operation, the eighth storage unit is the second storage unit in the production sequence along the tobacco production line that is before the seventh storage unit and adjacent to the seventh storage unit; In response to the material level status of the seventh storage unit being lower than a preset first threshold and the first state of the material handling equipment corresponding to the seventh storage unit meeting a preset first condition, a material batch switching instruction is sent to the material handling equipment corresponding to the seventh storage unit to cause the material handling equipment corresponding to the seventh storage unit to perform a material batch switching operation. The process then returns to detecting the material level status of the ninth storage unit in at least one second storage unit and the first state of the material handling equipment corresponding to the ninth storage unit until the material level status of the ninth storage unit is not lower than the preset first threshold and the first state of the material handling equipment corresponding to the ninth storage unit does not meet the preset first condition, or the ninth storage unit is the last second storage unit in the production sequence along the tobacco production line among the at least one second storage units, and the ninth storage unit is the second storage unit in the production sequence along the tobacco production line that is after the seventh storage unit and adjacent to the seventh storage unit.

[0065] Based on the above embodiments, optionally, the preset first condition includes at least the instantaneous material flow rate of the material metering device adjacent to the storage unit along the production sequence of the tobacco production line in the material handling equipment corresponding to the storage unit being zero, and the preset delay processing triggered by the material processing equipment in the material handling equipment corresponding to the storage unit having completed the tail material program or emptying program. The preset delay processing is used to ensure that all residual materials on the material processing equipment and the material processing equipment outlet conveying equipment are sent to the downstream storage unit.

[0066] Based on the above embodiments, optionally, before sending a material batch switching instruction to the material handling device corresponding to the seventh storage unit, the method further includes: In response to the material level status of the seventh storage unit being not lower than a preset first threshold or the first state of the material handling equipment corresponding to the seventh storage unit not meeting a preset first condition, the inlet conveying equipment and outlet conveying equipment of the eighth storage unit are locked. In response to the material level of the seventh storage unit being lower than a preset first threshold and the first state of the material handling equipment corresponding to the seventh storage unit meeting a preset first condition, the lock of the outlet conveying equipment of the eighth storage unit is released, and a material emptying confirmation operation is performed on the seventh storage unit and the material handling equipment corresponding to the seventh storage unit.

[0067] Optionally, based on the above embodiments, after the seventh storage unit and the material handling equipment corresponding to the seventh storage unit complete the material emptying confirmation operation, a material batch switching instruction is sent to the material handling equipment corresponding to the seventh storage unit and the lock of the inlet conveying equipment of the eighth storage unit is released.

[0068] Based on the above embodiments, optionally, before simultaneously sending material batch switching instructions to the material handling devices corresponding to the plurality of sixth storage units, the method further includes: The inlet and outlet conveying devices of the tenth storage unit among the plurality of sixth storage units are locked, while the inlet and outlet conveying devices of the sixth storage units other than the tenth storage unit are kept unlocked. The tenth storage unit is the last sixth storage unit in the production sequence along the tobacco production line among the plurality of sixth storage units.

[0069] The technical solution of this invention, by determining at least one second storage unit from multiple first storage units in a tobacco production line, clarifies the control object and management boundary of material batch switching. Based on the material level status of the second storage unit and the first state of the corresponding material handling equipment, the processing completion status of the first batch of materials by the corresponding material handling equipment can be determined. This avoids relying on conservative and time-consuming control methods such as extending emptying time or adding fixed delays, reducing the risk of material mixing between different batches, ensuring that the material handling equipment can promptly start preparations for processing the next batch of materials, and reducing unnecessary downtime of material handling equipment in the tobacco production line. This improves the execution efficiency of material batch switching in the tobacco production line. Based on the above technical solution, by using the storage unit as the management boundary for material batch switching operations in the tobacco production line, and controlling the material batch switching operations of the material handling equipment in the tobacco production line according to the material level status of the storage unit and the first state of the corresponding material handling equipment, the control logic for material batch switching can be optimized. This improves the continuous operation capability and equipment utilization rate of the tobacco production line, thereby enhancing the stability and production efficiency of tobacco production.

[0070] The material batch switching control device for the tobacco production line provided in this embodiment of the invention can execute the material batch switching control method for the tobacco production line provided in any embodiment of the invention, and has the corresponding functional modules and beneficial effects of the method.
