Description

Technical Field

[0001] This disclosure relates to the field of tobacco automatic control, and in particular to a method, system, and computer-readable storage medium for scheduling empty filter rod cartridges. Background Technology

[0002] Figure 1 This is a schematic plan view of a filter rod storage area device according to some embodiments of the present disclosure.

[0003] like Figure 1 As shown, the process for conveying empty filter cartridges in the filter cartridge library is as follows: the transmitter consumes filter cartridges to generate empty cartridges. The number of empty cartridges is obtained through the emission counting phototube 102 in the emission area 11. When the number reaches a certain set value, an empty cartridge storage request is generated, creating a stacker crane task for empty cartridge storage, which is then executed by the stacker crane 103. The emission area 11 includes an emission conveying station 105. This emission conveying station 105 includes an emission area storage station 1051 and an emission area production station 1052. Figure 1 The image also shows the filter rod empty box assembly 106.

[0004] Furthermore, such as Figure 1 As shown, the molding machine consumes empty boxes to produce filter rods for packaging. When the molding detection photocell 101 on the outer side of the shelf does not detect an empty box, it indicates that the empty box needs to be replenished. An empty box outbound request is initiated, generating an empty box outbound stacker crane task. The stacker crane 103 executes the empty box outbound operation. Figure 1 As shown, the molding area 12 includes a molding conveyor station 107. This molding conveyor station 107 includes a molding area outbound station 1071 and a molding area production station 1072. Additionally, Figure 1 The image also shows a molded counting phototube 104.

[0005] In related technologies, the consumption and replenishment of empty filter rod boxes are accomplished through the aforementioned scheduling process. Summary of the Invention

[0019] In some embodiments, when no filter rod empty box warehousing request is received, scheduling the filter rod empty boxes based on the time for each group of empty boxes to be grouped and stored at the launch area warehousing station and the time consumed by each group of empty boxes at the molding area warehousing station includes: calculating the waiting time for triggering the filter rod empty box warehousing request based on the time for each group of empty boxes to be grouped and stored at the launch area warehousing station, and calculating the minimum waiting time for warehousing based on the time consumed by each group of empty boxes at the molding area warehousing station; if the waiting time for triggering the filter rod empty box warehousing request is less than the minimum waiting time for warehousing, pre-binding the filter rod empty box warehousing request from the molding area warehousing station with the filter rod empty box warehousing request that will be generated by the launch area warehousing station and starting a timer, denoted as the second timer, and scheduling the filter rod empty boxes based on the second timer; and if the waiting time for triggering the filter rod empty box warehousing request is greater than or equal to the minimum waiting time for warehousing, generating an empty box warehousing task for the stacker crane, so that the stacker crane can transport the filter rod empty boxes in the high-bay warehouse to the molding area warehousing station.

[0020] In some embodiments, scheduling the empty filter cartridges according to the second timing includes: if the launch area receiving station generates an empty filter cartridge receiving request before the second timing reaches the time for waiting to trigger the empty filter cartridge receiving request, then the pre-binding of the empty filter cartridge receiving request and the upcoming empty filter cartridge receiving request from the launch area receiving station is changed to a direct scheduling task for a stacker crane, so that the stacker crane directly transports the empty filter cartridges from the launch area receiving station to the forming area receiving station; if the launch area receiving station has not generated an empty filter cartridge receiving request before the second timing reaches the time for waiting to trigger the empty filter cartridge receiving request, then the pre-binding of the empty filter cartridge receiving request and the upcoming empty filter cartridge receiving request from the launch area receiving station is canceled, and an empty cartridge receiving task for a stacker crane is generated, so that the stacker crane transports the empty filter cartridges in the high-bay warehouse to the forming area receiving station.

[0021] In some embodiments, the relationship between the time for waiting to trigger the empty filter rod box storage request and the time for group storage of each group of empty boxes at the launch area storage station is as follows:

[0022]

[0023] Among them, T rd M is the time for waiting to trigger the request to put empty filter rod boxes into storage. r M represents the number of empty filter rod boxes that have arrived at the launch area storage station. a T represents the maximum number of empty boxes per filter rod group. r This refers to the time required for each group of empty boxes to be stored in the launch area's storage station.

[0024] In some embodiments, the formula for calculating the minimum waiting time for outbound shipment based on the time consumed by each group of empty boxes at the outbound station in the forming area is as follows:

[0025] T cmin =(T c -T x )×a,

[0028] In some embodiments, the average grouping time T for empty filter rod boxes of each group is calculated. r The relation is: T r =(T m +T m-1 ) / 2,

[0029] Among them, T m-1 This is the time for the last accumulated empty filter cartridge supply.

[0031] In some embodiments, the average consumption time T of each set of filter rod empty boxes is calculated. c The relation is: T c =(T n +T n-1 ) / 2,

[0032] Among them, T n-1 This is the time consumed by the previously accumulated empty filter cartridge.

[0049] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0050] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0051] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0052] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0053] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0055] The inventors of this disclosure have discovered that the empty box scheduling strategy in related technologies has certain drawbacks. For example... Figure 1 As shown, the launch area's receiving station sends a receiving request, the system generates a receiving task and sorts it for the stacker crane. After receiving the task, the stacker crane 103 transports the empty boxes to the high-bay warehouse (not shown) for storage. Subsequently, if the molding machine needs empty boxes immediately, the molding area's outgoing station sends an empty box outgoing request to the system. The system generates an empty box outgoing task and sorts it for the stacker crane. After receiving the task, the stacker crane 103 transports the empty boxes from the high-bay warehouse to the molding area's outgoing station. Because the empty box receiving and outgoing tasks need to be sorted by the stacker crane, sometimes there is a shortage of empty boxes. Furthermore, if the launcher's empty boxes are full and the molding machine needs them immediately, an immediate outgoing task is required, significantly increasing the stacker crane's workload. Moreover, the immediate outgoing of empty boxes after receiving them also significantly impacts the time occupied and allocated in the high-bay warehouse, affecting the conveying efficiency of the filter rod warehouse. Therefore, in this related technology, the system's flexible scheduling capability is low.

[0056] In view of this, this disclosure provides a scheduling method for empty filter rod boxes to improve the system's flexible scheduling capability.

[0057] Figure 2 This is a flowchart illustrating a method for scheduling empty filter rod cartridges according to some embodiments of the present disclosure. Figure 2 As shown, the scheduling method includes steps S202 to S204.

[0058] In step S202, at least one of the following is obtained: a filter rod empty box warehousing request from the launch area warehousing station and a filter rod empty box outgoing request from the molding area warehousing station. The time for each group of empty boxes to be warehoused at the launch area warehousing station and the time consumed by each group of empty boxes at the molding area warehousing station are also obtained. Here, "time" refers to duration, and the same applies below.

[0059] In step S204, the filter rod empty boxes are scheduled according to at least one of the filter rod empty box storage request and the filter rod empty box release request, the time for each group of empty boxes to be stored in the launch area storage station, and the time consumed by each group of empty boxes at the forming area release station.

[0060] Here, scheduling of empty filter rod boxes includes: binding the empty filter rod box outbound task and the empty filter rod box inbound task to generate a direct scheduling task for the stacker crane so that the stacker crane can directly transport the empty filter rod boxes from the launch area inbound station to the molding area outbound station; or, generating an empty box inbound task for the stacker crane so that the stacker crane can perform the empty filter rod box inbound operation (i.e., transport the empty filter rod boxes from the launch area inbound station to the high-bay warehouse), or generating an empty box outbound task for the stacker crane so that the stacker crane can perform the empty filter rod box outbound operation (i.e., transport the empty filter rod boxes from the high-bay warehouse to the molding area outbound station).

[0061] For example, after obtaining the filter rod empty box entry request from the launch area entry station and the filter rod empty box exit request from the molding area exit station, the system then obtains the time for each group of empty boxes to be entered into the launch area and the time consumed for each group of empty boxes at each molding area station. Then, based on the filter rod empty box entry and exit requests, the system performs judgment, binding, and processing to generate a stacker crane scheduling task; the stacker crane executes the corresponding entry and exit tasks, completing the empty box entry and exit responses for the launch area entry station and the molding area exit station. For example, when generating the inbound / outbound request for empty filter rod boxes, two situations are judged: (1) If there are corresponding empty boxes that need to be inbound / outbound within the set time, then the outbound and inbound tasks are bound together, and a stacker crane transportation task is generated to directly transport the empty boxes from the inbound station to the outbound station, thus completing the empty box inbound / outbound response of the inbound station and the outbound station; (2) If there are no corresponding empty boxes that need to be inbound / outbound within the set time, then a stacker crane empty box inbound task is generated to transport the empty filter rod boxes from the inbound station to the high-bay warehouse, or a stacker crane empty box outbound task is generated to transport the empty filter rod boxes from the high-bay warehouse to the outbound station, thus completing the empty box inbound / outbound response of the inbound station and the outbound station.

[0062] In the example above, the stacker crane directly transports the empty filter rod boxes from the launch area's inbound station to the forming area's outbound station instead of storing them in the high-bay warehouse. This improves the system's flexible scheduling capabilities, increases the conveying efficiency of the filter rod warehouse, and reduces the time that empty boxes occupy in the high-bay warehouse.

[0063] Thus, a method for scheduling empty filter rod boxes according to some embodiments of the present disclosure is provided. The method includes: acquiring at least one of a filter rod empty box warehousing request from the launch area warehousing station and a filter rod empty box outgoing request from the molding area outgoing station; acquiring the time for each group of empty boxes to be warehoused at the launch area warehousing station and the time consumed by each group of empty boxes at the molding area outgoing station; and scheduling the filter rod empty boxes according to at least one of the filter rod empty box warehousing request and the filter rod empty box outgoing request, the time for each group of empty boxes to be warehoused at the launch area warehousing station and the time consumed by each group of empty boxes at the molding area outgoing station, wherein scheduling the filter rod empty boxes includes: binding the filter rod empty box outgoing task and the filter rod empty box warehousing task to generate a direct scheduling task for the stacker crane so that the stacker crane can directly transport the filter rod empty boxes from the launch area warehousing station to the molding area outgoing station; or, generating an empty box warehousing task for the stacker crane so that the stacker crane can perform the filter rod empty box warehousing operation, or generating an empty box outgoing task for the stacker crane so that the stacker crane can perform the filter rod empty box outgoing operation. This method can improve the system's flexible scheduling capability, increase the conveying efficiency of the filter rod library, and reduce the time that empty boxes are occupied in the high-bay warehouse.

[0064] In some embodiments, obtaining the time consumed by each group of empty boxes at the forming area outbound station includes: after receiving the empty box group arrival signal, initializing the filter rod empty box consumption time to 0, assigning the consumption quantity of filter rod empty boxes to a predetermined value, starting the timer, and accumulating the filter rod empty box consumption time every second, wherein the predetermined value is the maximum number of filter rod empty boxes per group; detecting and counting the consumption quantity of filter rod empty boxes, the count is decremented one by one, and when the consumption quantity of filter rod empty boxes is equal to 0, it indicates that the production and consumption of filter rod empty boxes is completed, and recording the currently accumulated filter rod empty box consumption time T. n And based on the accumulated consumption time of the empty filter cartridges obtained multiple times corresponding to each group of empty filter cartridges, calculate the average consumption time T of each group of empty filter cartridges. c This refers to the time consumed by each group of empty boxes at the forming area's outbound station. This achieves the goal of obtaining the time consumed by each group of empty boxes at the forming area's outbound station, enabling scheduling of the filter rod empty boxes.

[0065] It should be noted that, in the embodiments of this disclosure, the maximum number of filter rod empty boxes per group refers to the maximum number of filter rod empty boxes contained in each filter rod empty box group (i.e., the filter rod empty boxes that make up a group).

[0066] In some embodiments, the average consumption time T of each set of filter rod empty boxes is calculated. c The relation is:

[0067] T c = (T) n +T n-1 ) / twenty one)

[0068] Among them, T n-1This represents the time consumed by the previously accumulated empty filter rod box. Here, n ≥ 2, where n is a positive integer.

[0069] In this embodiment, the average consumption time of a certain group of filter rod empty boxes in the two most recent times is used as the average consumption time of that group of filter rod empty boxes. The consumption time of a certain group of empty boxes at the forming area outbound station can be updated in real time, and then the consumption time of each group of empty boxes at the forming area outbound station can be updated. In this way, the real-time updated empty box consumption time data can be used for subsequent judgment and processing, which can better improve the scheduling capability of the system.

[0070] It should be noted that the above embodiments describe using the average of the two most recent empty cartridge consumption times of a certain group of filter rods as the average consumption time of that group of filter rods, but the scope of this disclosure is not limited thereto. For example, the average of more than one empty cartridge consumption time of a certain group of filter rods can be used as the average consumption time of that group of filter rods.

[0071] Figure 3 This is a flowchart illustrating a method for obtaining the time consumed by each group of empty boxes at the forming area outbound station according to some embodiments of this disclosure. Figure 3 As shown, the method includes steps S302 to S316.

[0072] In step S302, an empty box group arrival signal is received. For example, when the forming area outbound station requests an empty box, the stacker crane transports the empty box to the outbound station, the detection phototube 101 illuminates the empty box group with goods, thereby triggering the empty box group arrival signal, and the system receives the empty box group arrival signal.

[0073] In step S304, the initial empty filter cartridge consumption time is 0, and the empty filter cartridge consumption quantity Mc is assigned a predetermined value.

[0074] This predetermined value is the total number of empty filter cartridges in each group (e.g., a set). For example, the predetermined value is 13. It should be noted that this predetermined value can be set according to actual needs or circumstances, and is not limited to the specific values ​​listed here.

[0075] In step S306, the empty box consumption time is accumulated. That is, timing begins, and the empty box consumption time is accumulated every second.

[0076] In step S308, empty cell consumption is detected. For example, the number of empty cells consumed, Mc, is detected and counted by the forming counting phototube 104.

[0077] In step S310, the number of empty cells consumed is decremented by Mc. For example, when the detection and counting are performed by the forming counting phototube 104, after the forming counting phototube 104 illuminates the empty cells, the number of empty cells is decremented one by one by the falling edge, that is, Mc-1, and Mc-1 is stored in Mc.

[0078] In step S312, it is determined whether the empty box consumption is complete. If yes, the process proceeds to step S314; otherwise, the process returns to steps S306 and S308, that is, the empty box consumption time accumulation and empty box consumption detection continue.

[0079] In step S314, the cumulative time Tn is recorded. That is, when the number of empty boxes consumed Mc equals 0, it indicates that the production and consumption of empty boxes is completed, and the current cumulative empty box consumption time Tn is recorded.

[0080] It should be noted that whenever the number of empty filter rod boxes consumed equals 0, the accumulated time T for consuming empty filter rod boxes is recorded. n To obtain a T n If you need to obtain multiple T n Then, steps S302 to S314 will be executed repeatedly.

[0081] In step S316, the cumulative consumption time of the filter rod empty boxes in the two most recent times is obtained, and the average consumption time Tc of each group of empty boxes is calculated using the following formula: T c =(T n +T n-1 ) / 2.

[0082] This provides a method for obtaining the time consumed by each group of empty boxes at the forming area outbound station according to some embodiments of the present disclosure. This method can update the time consumed by each group of empty boxes at the forming area outbound station in real time, allowing for subsequent judgment and processing using the real-time updated empty box consumption time data, thus improving the system's scheduling capabilities.

[0083] In some embodiments, obtaining the time for each group of empty boxes to be stored in the launch area storage station includes: after receiving the empty box group clearing signal, initializing the filter rod empty box supply time to 0, setting the number of empty filter rod boxes stored to 0, and starting a timer to accumulate the filter rod empty box supply time every second; detecting the number of empty filter rod boxes stored, which is incremented one by one, and when the number of empty filter rod boxes stored equals a predetermined value, it indicates that the number of empty filter rod boxes stored has been reached, and recording the currently accumulated filter rod empty box supply time T. m The predetermined value is the maximum number of empty filter rod boxes per group; the average group entry time T for each group of empty filter rod boxes is calculated based on the cumulative supply time of multiple empty filter rod boxes corresponding to each group of empty filter rod boxes. r This refers to the time when each group of empty boxes is grouped and stored at the launch area storage station. This achieves the goal of obtaining the time when each group of empty boxes is grouped and stored at the launch area storage station, enabling scheduling of the filter rod empty boxes.

[0084] In some embodiments, the average grouping time T for empty filter rod boxes of each group is calculated. r The relation is: T r =(Tm +T m-1 ) / 2,(2)

[0085] Among them, T m-1 This is the supply time for the previously accumulated empty filter rod box. Here, m ≥ 2, where m is a positive integer.

[0086] In this embodiment, the average of the cumulative supply times of a certain group of empty filter rod boxes from the two most recent times is used as the average group entry time of that group of empty filter rod boxes. This allows for real-time updates of the group entry time of that group of empty boxes at the launch area entry station, and further updates of the group entry time of each group of empty boxes at the launch area entry station. This enables subsequent judgment and processing using the real-time updated group entry time data of empty boxes, thereby improving the system's scheduling capabilities.

[0087] It should be noted that the above embodiment describes using the average of the cumulative supply times of the two most recent batches of empty filter rod boxes as the average group warehousing time for that batch of empty filter rod boxes, but the scope of this disclosure is not limited thereto. For example, the average of the cumulative supply times of more batches of empty filter rod boxes can be used as the average group warehousing time for that batch of empty filter rod boxes.

[0088] Figure 4 This is a flowchart illustrating a method for obtaining the time of grouped storage of each set of empty boxes at the launch area storage station according to some embodiments of this disclosure. For example... Figure 4 As shown, the method includes steps S402 to S416.

[0089] In step S402, an empty box group clearing signal is received. For example, when the stacker crane takes away the empty box from the receiving station after a request from the launch area storage station, the launch probe photocell successfully emits an empty box group clearing signal, and the system receives the empty box group clearing signal.

[0090] In step S404, the filter rod empty box supply time is initialized to 0, and the number of filter rod empty boxes Mr entering the warehouse is assigned a value of 0.

[0091] In step S406, the empty box supply time is accumulated. That is, timing begins, and the empty box supply time is accumulated every second.

[0092] In step S408, empty box entry detection is performed. For example, the number of empty boxes Mr is detected and counted by the emission counting phototube 102.

[0093] In step S410, the number of empty boxes stored is incremented by Mr. For example, when the detection and counting are performed by the emission counting phototube 102, after the emission counting phototube 102 illuminates the empty box, the number of empty boxes is incremented one by one by the falling edge, that is, Mr+1, and Mr+1 is stored in Mr.

[0094] In step S412, it is determined whether the number of empty filter rod boxes received is equal to a predetermined value. If yes, the process proceeds to step S414; otherwise, the process returns to steps S406 and S408, that is, the accumulation of empty box supply time and empty box receipt detection continue.

[0095] In step S414, the cumulative time Tm is recorded. That is, when the number of empty boxes Mr in the warehouse equals the predetermined value, it means that the number of empty boxes in the warehouse has been reached, and the current cumulative empty box supply time Tm is recorded.

[0096] This predetermined value is the total number of empty filter cartridges in each group (e.g., a set). For example, the predetermined value is 13. It should be noted that this predetermined value can be set according to actual needs or circumstances, and is not limited to the specific values ​​listed here.

[0097] It should be noted that whenever the number of empty boxes Mr in the warehouse equals the predetermined value, the accumulated empty box supply time Tm is recorded as one Tm is obtained; if multiple Tm needs to be obtained, steps S402 to S414 are repeated multiple times.

[0098] In step S416, the supply times of the two most recent accumulated empty filter cartridges are obtained, and the average group entry time Tr for each group of empty cartridges is calculated using the following formula: T r =(T m +T m-1 ) / 2.

[0099] This provides a method for obtaining the time of grouped empty boxes being stored at the launch area storage station according to some embodiments of the present disclosure. This method can update the time of grouped empty boxes being stored at the launch area storage station in real time, allowing for subsequent judgment and processing using the real-time updated data, thus improving the system's scheduling capabilities.

[0100] In some embodiments, obtaining at least one of the filter rod empty box inbound request and filter rod empty box outbound request includes: obtaining the filter rod empty box inbound request.

[0101] In some embodiments, step S204 includes: if a filter rod empty box inbound request is received, determining whether a filter rod empty box outbound request is received; if a filter rod empty box outbound request is received, binding the filter rod empty box inbound request with the filter rod empty box outbound request to generate a direct scheduling task for the stacker crane, so that the stacker crane can directly transport the filter rod empty boxes from the launch area inbound station to the forming area outbound station; and if no filter rod empty box outbound request is received, scheduling the filter rod empty boxes according to the time for each group of empty boxes to be inbound at the launch area inbound station and the time consumed by each group of empty boxes at the forming area outbound station. This can improve the system's flexible scheduling capability, improve the conveying efficiency of the filter rod warehouse, and reduce the time occupied by empty box storage locations in the high-bay warehouse.

[0102] In some embodiments, when no filter rod empty box outbound request is obtained, scheduling filter rod empty boxes based on the time for each group of empty boxes to be grouped and stored at the launch area inbound station and the time consumed by each group of empty boxes at the molding area outbound station includes: calculating the waiting time for triggering the filter rod empty box outbound request based on the time consumed by each group of empty boxes at the molding area outbound station, and calculating the minimum waiting time for inbound storage based on the time for each group of empty boxes to be grouped and stored at the launch area inbound station; if the waiting time for triggering the filter rod empty box outbound request is less than the minimum waiting time for inbound storage, pre-binding the filter rod empty box inbound request of the launch area inbound station with the filter rod empty box outbound request that will be generated by the molding area outbound station and starting the timing, denoted as the first timing, and scheduling the filter rod empty boxes based on the first timing; and if the waiting time for triggering the filter rod empty box outbound request is greater than or equal to the minimum waiting time for inbound storage, generating an empty box inbound task for the stacker crane, so that the stacker crane can transport the filter rod empty boxes of the launch area inbound station to the high-bay warehouse for storage.

[0103] It should be noted that in the above embodiments, since the filter rod empty box release request has not yet been generated at the molding area release station, the filter rod empty box release request that is about to be generated at the molding area release station can be an assumed filter rod empty box release request event for the convenience of method execution, so as to pre-bind the filter rod empty box entry request of the launch area entry station with the filter rod empty box release request that is about to be generated at the molding area release station. This upcoming filter rod empty box release request can be a filter rod empty box release request generated within a first predetermined time period.

[0104] In some embodiments, scheduling the empty filter cartridges according to the first timing includes: if the forming area outbound station generates an empty filter cartridge outbound request before the first timing has elapsed and the time for waiting to trigger the empty filter cartridge outbound request has been reached, then the pre-binding of the empty filter cartridge inbound request and the empty filter cartridge outbound request to be generated by the forming area outbound station is changed to a direct scheduling task of the stacker crane, so that the stacker crane directly transports the empty filter cartridges from the launch area inbound station to the forming area outbound station; if the forming area outbound station has not generated an empty filter cartridge outbound request before the first timing has elapsed and the time for waiting to trigger the empty filter cartridge outbound request has been reached, then the pre-binding of the empty filter cartridge inbound request and the empty filter cartridge outbound request to be generated by the forming area outbound station is canceled, and an empty cartridge inbound task of the stacker crane is generated, so that the stacker crane transports the empty filter cartridges from the launch area inbound station to the high-bay warehouse for storage.

[0105] The above embodiments can improve the system's flexible scheduling capability, increase the conveying efficiency of the filter rod library, and reduce the time occupied by empty boxes in the high-bay warehouse.

[0106] In some embodiments, the formula for calculating the waiting time for triggering the filter rod empty box dispatch request based on the time consumed by each group of empty boxes at the forming area dispatch station is as follows:

[0107]

[0108] Among them, T cd M is the time to wait for the triggering of the empty filter rod box outbound request. c M represents the number of remaining empty boxes at the production station in the molding area corresponding to the outbound station in the molding area. a T represents the maximum number of empty boxes per filter rod group. c The time consumed for each group of empty boxes at the forming area's outbound platform.

[0109] For example, M a The maximum number of empty filter rod boxes M per set is 13. Of course, those skilled in the art will understand that the maximum number M of empty boxes per set of filter rods in this disclosure is... c The values ​​can be set according to the actual situation and are not limited to the specific values ​​shown here.

[0110] In some embodiments, the formula for calculating the minimum waiting time for storage based on the time it takes for each group of empty boxes to be stored in the launch area storage station is as follows:

[0111] T rmin =(T r +T x )×a, (4)

[0112] Among them, T rmin T is the minimum waiting time for warehousing. r T is the time for each group of empty boxes to be stored in the launch area storage station. x Let T be the average time for the stacker crane to perform a task, 'a' be the task scheduling coefficient, and 'T' be the average time for the stacker crane to perform a task. x And 'a' are known quantities. For example, T x 'a' and 'a' can be obtained through measurement or testing.

[0113] It should be noted that because the stacker crane task scheduling is affected by location and the number of tasks, the time for transporting goods to the platform is unpredictable. Therefore, a task scheduling coefficient 'a' was determined through testing. For example, the task scheduling coefficient 'a' ranges from 0.5 to 0.7. Specifically, when the number of tasks scheduled by the stacker crane is less than 4, the task scheduling coefficient 'a' is 0.5; when the number of tasks scheduled by the stacker crane is between 4 and 6, the task scheduling coefficient 'a' is 0.6; and when the number of tasks scheduled by the stacker crane is greater than 6, the task scheduling coefficient 'a' is 0.7.

[0114] Figure 5 This is a flowchart illustrating a control method for requesting empty filter rod cartridges to be stored, according to some embodiments of this disclosure. Figure 5 As shown, the method includes steps S502 to S528.

[0115] In step 502, a request for empty filter rod cartridges to be stored in the emission area is obtained.

[0116] In step 504, it is detected whether there is a request for empty filter rod boxes to be shipped out in the forming area. That is, it is determined whether a request for empty filter rod boxes to be shipped out has been received. If yes, the process proceeds to step S522; otherwise, the process proceeds to step S506.

[0117] In step 506, the waiting time T for triggering the empty filter rod box release request at each outbound station in the molding area is detected. cd .

[0118] In step S508, determine T cd Is it less than T? rmin T rmin The minimum waiting time for warehousing. If so, the process proceeds to step S510; otherwise, the process proceeds to step S518.

[0119] In step S510, the empty box entry request in the launch area is pre-bound to the empty box exit request that will be generated in the forming area.

[0120] In step S512, wait for the timing △T1, which is the first timing.

[0121] In step S514, determine whether △T1 is greater than or equal to T. cd If yes, the process proceeds to step S518; otherwise, the process proceeds to step S516.

[0122] In step S516, it is detected whether the pre-bound station in the forming area has generated an empty box outbound request. If so, the process proceeds to step S522; otherwise, the process returns to step S514.

[0123] In step S518, a task for storing empty filter rod boxes in the high-bay warehouse is generated.

[0124] In step S520, the stacker crane is dispatched to retrieve empty boxes from the launch area storage station and place them in the elevated warehouse for storage.

[0125] In step S522, the request for empty cartridges to be stored in the launch area is bound to the request for empty cartridges to be released from the molding area.

[0126] In step S524, a stacker crane scheduling task is generated.

[0127] In step S526, the dispatch stacker crane directly delivers the empty boxes from the launch area's inbound station to the forming area's outbound station.

[0128] In step S528, the empty cartridge of the emission area filter rod is put into storage.

[0129] Thus, a control method for filter rod empty box warehousing requests according to some embodiments of this disclosure is provided. In this method, when the system obtains a warehousing request for filter rod empty boxes in the launch area, it determines and detects two situations: (1) if there is a request for filter rod empty box warehousing in the molding area, the warehousing request for empty boxes in the launch area is bound to the request for empty boxes warehousing in the molding area, and then the system generates a stacker crane scheduling task, scheduling the stacker crane to directly transport the empty boxes from the launch area warehousing station to the molding area warehousing station; (2) if there is no request for filter rod empty box warehousing in the molding area, the system will detect each warehousing station T in the molding area. cd Is the time (waiting for a request to release empty filter cartridges) less than T? rmin (Minimum waiting time for warehousing).

[0130] When T cd <T rmin When, it indicates that the empty box consumption flow in the forming area is within the minimum waiting time T for warehousing. rmin An outbound request will be generated. The system will pre-bind the filter rod empty box inbound request from the launch area storage station with the empty box outbound request that will be generated from the molding area and start timing, denoted as the first timing △T1: If the waiting time T for triggering the filter rod empty box outbound request is not reached in the first timing △T1: cd When the filter rod empty box outbound request is generated at the molding area outbound station, the pre-binding of the filter rod empty box inbound request at the launch area inbound station and the filter rod empty box outbound request to be generated at the molding area outbound station is changed to a direct scheduling task for the stacker crane, so that the stacker crane can directly transport the filter rod empty box from the launch area inbound station to the molding area outbound station; if the first timer △T1 reaches the waiting time T for triggering the filter rod empty box outbound request... cd If the filter rod empty box outbound request has not yet been generated at the molding area outbound station, the pre-binding of the filter rod empty box inbound request at the launch area inbound station with the filter rod empty box outbound request that will be generated at the molding area outbound station will be canceled, and an empty box inbound task for the stacker crane will be generated. That is, an empty box inbound task for the high-bay warehouse will be generated directly, so that the stacker crane can directly transport the filter rod empty box at the launch area inbound station to the high-bay warehouse for storage.

[0131] When T cd ≥T rmin When, it indicates that the empty box consumption flow in the forming area is within the minimum waiting time T for warehousing. rmin No outbound request will be generated. Instead, an empty box inbound task will be generated directly in the high-bay warehouse. The stacker crane will directly deliver the empty boxes from the launch area inbound station to the high-bay warehouse for storage.

[0132] The above methods can improve the system's flexible scheduling capabilities, increase the conveying efficiency of the filter rod storage, and reduce the time that empty boxes are occupied in the high-bay storage.

[0133] In some embodiments, obtaining at least one of the filter rod empty box inbound request and filter rod empty box outbound request includes: obtaining the filter rod empty box outbound request.

[0134] In some embodiments, step S204 includes: if a filter rod empty box outbound request is received, determining whether a filter rod empty box inbound request is received; if a filter rod empty box inbound request is received, binding the filter rod empty box inbound request with the filter rod empty box outbound request to generate a direct scheduling task for the stacker crane, so that the stacker crane can directly transport the filter rod empty boxes from the launch area inbound station to the forming area outbound station; and if no filter rod empty box inbound request is received, scheduling the filter rod empty boxes according to the time for each group of empty boxes to be grouped and stored at the launch area inbound station and the time consumed by each group of empty boxes at the forming area outbound station. This can improve the system's flexible scheduling capability, improve the conveying efficiency of the filter rod warehouse, and reduce the time the empty box storage space in the high-bay warehouse is occupied.

[0135] In some embodiments, when no filter rod empty box warehousing request is received, scheduling filter rod empty boxes based on the time for each group of empty boxes to be grouped and stored at the launch area warehousing station and the time consumed by each group of empty boxes at the molding area warehousing station includes: calculating the waiting time for triggering a filter rod empty box warehousing request based on the time for each group of empty boxes to be grouped and stored at the launch area warehousing station, and calculating the minimum waiting time for warehousing based on the time consumed by each group of empty boxes at the molding area warehousing station; if the waiting time for triggering a filter rod empty box warehousing request is less than the minimum waiting time for warehousing, pre-binding the filter rod empty box warehousing request from the molding area warehousing station with the filter rod empty box warehousing request that will be generated by the launch area warehousing station and starting a timer, denoted as the second timer, and scheduling filter rod empty boxes based on the second timer; and if the waiting time for triggering a filter rod empty box warehousing request is greater than or equal to the minimum waiting time for warehousing, generating an empty box warehousing task for the stacker crane so that the stacker crane can transport the filter rod empty boxes in the high-bay warehouse to the molding area warehousing station.

[0136] It should be noted that in the above embodiments, since the launch area receiving station has not yet generated a filter rod empty box receiving request, the filter rod empty box receiving request that the launch area receiving station is about to generate can be an assumed filter rod empty box receiving request event for the convenience of method execution, so as to pre-bind the filter rod empty box outgoing request of the molding area outgoing station with the filter rod empty box receiving request that the launch area receiving station is about to generate. This upcoming filter rod empty box receiving request can be a filter rod empty box receiving request generated within a second predetermined time period.

[0137] In some embodiments, scheduling the empty filter cartridges according to the second timing includes: if the launch area receiving station generates an empty filter cartridge receiving request before the second timing has elapsed and the time for waiting to trigger the empty filter cartridge receiving request has been reached, then the pre-binding of the empty filter cartridge outgoing request and the empty filter cartridge receiving request to be generated by the launch area receiving station is changed to a direct scheduling task of the stacker crane, so that the stacker crane directly transports the empty filter cartridges from the launch area receiving station to the forming area outgoing station; if the launch area receiving station has not generated an empty filter cartridge receiving request before the second timing has elapsed and the time for waiting to trigger the empty filter cartridge receiving request has been reached, then the pre-binding of the empty filter cartridge outgoing request and the empty filter cartridge receiving request to be generated by the launch area receiving station is canceled, and an empty cartridge outgoing task of the stacker crane is generated, so that the stacker crane transports the empty filter cartridges in the high-bay warehouse to the forming area outgoing station.

[0138] The above embodiments can improve the system's flexible scheduling capability, increase the conveying efficiency of the filter rod library, and reduce the time occupied by empty boxes in the high-bay warehouse.

[0139] In some embodiments, the formula for calculating the waiting time for triggering the filter rod empty box storage request based on the time for each group of empty boxes to be stored in the launch area storage station is as follows:

[0140]

[0141] Among them, T rd M is the time to wait for the triggering of the empty filter rod box storage request. r M represents the number of empty filter rod boxes that have arrived at the launch area storage station. a T represents the maximum number of empty boxes per filter rod group. r This refers to the time required for each group of empty boxes to be stored in the launch area's storage station.

[0142] For example, M a The maximum number of empty filter rod boxes M per set is 13. Of course, those skilled in the art will understand that the maximum number M of empty boxes per set of filter rods in this disclosure is... c The values ​​can be set according to the actual situation and are not limited to the specific values ​​shown here.

[0143] In some embodiments, the formula for calculating the minimum waiting time for outbound delivery based on the time consumed by each group of empty boxes at the outbound station in the forming area is as follows:

[0144] T cmin =(T c -T x )×a, (6)

[0145] Among them, T cmin T is the minimum waiting time for outbound shipment. c T represents the time consumed by each group of empty boxes at the forming area's outbound platform. xLet T be the average time for the stacker crane to perform a task, 'a' be the task scheduling coefficient, and 'T' be the average time for the stacker crane to perform a task. x And 'a' are known quantities. For example, T x 'a' and 'a' can be obtained through measurement or testing.

[0146] It should be noted that because the stacker crane task scheduling is affected by location and the number of tasks, the time for transporting goods to the platform is unpredictable. Therefore, a task scheduling coefficient 'a' was determined through testing. For example, the task scheduling coefficient 'a' ranges from 0.5 to 0.7. Specifically, when the number of tasks scheduled by the stacker crane is less than 4, the task scheduling coefficient 'a' is 0.5; when the number of tasks scheduled by the stacker crane is between 4 and 6, the task scheduling coefficient 'a' is 0.6; and when the number of tasks scheduled by the stacker crane is greater than 6, the task scheduling coefficient 'a' is 0.7.

[0147] Figure 6 This is a flowchart illustrating a control method for requesting the release of empty filter rod cartridges according to some embodiments of the present disclosure. Figure 6 As shown, the method includes steps S602 to S628.

[0148] In step S602, a request to release empty filter rod boxes from the forming area is obtained.

[0149] In step S604, it is detected whether there is a request for empty filter rod cartridges to be stored in the emission area. That is, it is determined whether a request for empty filter rod cartridges to be stored has been obtained. If yes, the process proceeds to step S622; otherwise, the process proceeds to step S606.

[0150] In step S606, the time T for each storage station in the launch area to wait for the triggering of the filter rod empty box storage request is detected. rd .

[0151] In step S608, determine T rd Is it less than T? cmin T cmin The minimum waiting time for outbound shipment is set. If so, the process proceeds to step S610; otherwise, the process proceeds to step S618.

[0152] In step S610, the empty box outbound request from the forming area is pre-bound with the empty box inbound request that will be generated in the launch area.

[0153] In step S612, wait for the timing △T2, which is the second timing.

[0154] In step S614, determine whether △T2 is greater than or equal to T. rd If yes, the process proceeds to step S618; otherwise, the process proceeds to step S616.

[0155] In step S616, it is detected whether the pre-bound station in the launch area has generated an empty box storage request. If so, the process proceeds to step S622; otherwise, the process returns to step S614.

[0156] In step S618, a task for storing empty filter rod boxes in the high-bay warehouse is generated.

[0157] In step S620, the stacker crane is dispatched to retrieve empty boxes from the launch area storage station and place them in the elevated warehouse for storage.

[0158] In step S622, the empty box outbound request from the molding area is bound to the empty box inbound request from the launch area.

[0159] In step S624, a stacker crane scheduling task is generated.

[0160] In step S626, the dispatch stacker crane directly delivers the empty boxes from the launch area receiving station to the forming area delivery station.

[0161] In step S628, the empty filter rod box in the forming area is supplied.

[0162] Thus, a control method for filter rod empty box outbound requests according to some embodiments of the present disclosure is provided. In this method, when the system obtains an outbound request for filter rod empty boxes from the molding area, it determines and detects two situations: (1) if there is a request for filter rod empty box inbound from the launch area, the launch area empty box inbound request is bound to the molding area empty box outbound request, and then the system generates a stacker crane scheduling task, scheduling the stacker crane to directly transport the empty boxes from the launch area inbound station to the molding area outbound station; (2) if there is no request for filter rod empty box inbound from the launch area, the system will detect each inbound station T in the launch area. rd Is the time (waiting for the triggering of the filter rod empty box inbound request) less than T? cmin (Minimum waiting time for outbound shipment).

[0163] When T rd <T cmin When, it indicates that the empty box generated flow rate in the launch area is within the minimum waiting time T before leaving the warehouse. cmin An inbound request will be generated. The system will pre-bind the filter rod empty box outbound request from the molding area's outbound station with the empty box inbound request that will be generated in the launch area and start timing, which is the second timing △T2: If the waiting time T for triggering the filter rod empty box inbound request has not been reached in the second timing △T2... rd When an empty box warehousing request is generated in the launch area, the pre-binding of the filter rod empty box warehousing request at the molding area's outbound station with the upcoming empty box warehousing request in the launch area is changed to a binding to generate a stacker crane scheduling task, so that the stacker crane can directly deliver the empty boxes from the launch area's inbound station to the molding area's outbound station; if the second timer △T2 reaches the waiting time T for triggering the filter rod empty box warehousing request... rdIf no empty box warehousing request has been generated in the launch area, the pre-binding of the filter rod empty box warehousing request from the molding area warehousing station with the empty box warehousing request that will be generated in the launch area will be canceled, and an empty box warehousing task for the stacker crane will be generated. That is, an empty box warehousing task for the high-bay warehouse will be generated directly so that the stacker crane can transport the filter rod empty boxes in the high-bay warehouse to the molding area warehousing station.

[0164] When T rd ≥T cmin At that time, the launch area will not generate an inbound request within the minimum waiting time for outbound, and will directly generate an empty box outbound task from the high-bay warehouse. The stacker crane will directly deliver the empty boxes in the high-bay warehouse to the outbound station in the forming area.

[0165] The above methods can improve the system's flexible scheduling capabilities, increase the conveying efficiency of the filter rod storage, and reduce the time that empty boxes are occupied in the high-bay storage.

[0166] In the filter rod empty box scheduling method of this disclosure embodiment, the filter rod library system automatically adjusts the allocation of tasks based on the empty box supply, empty box consumption flow and time of the demand objects (transmitter and molding machine). When the empty boxes are full, it determines whether to send the empty boxes directly from the transmitter to the molding machine to replenish the empty boxes or to put the empty boxes of the transmitter into the library. This improves the system's flexible scheduling capability, improves the conveying efficiency of the filter rod library, and reduces the time occupied by the empty box storage space in the high-bay warehouse.

[0167] By adopting the above-mentioned empty filter rod box scheduling method, the workload of the filter rod storage stacker crane is reduced, thus decreasing the time that empty boxes spend in the high-bay storage and improving the conveying efficiency of the filter rod storage. Furthermore, it also reduces the risk of material shortages due to excessive task execution to some extent.

[0168] Figure 7 This is a schematic structural diagram illustrating a scheduling system for empty filter rod cartridges according to some embodiments of the present disclosure. Figure 7 As shown, the scheduling system includes an acquisition unit 710 and a scheduling unit 720.

[0169] The acquisition unit 710 is used to acquire at least one of the filter rod empty box entry request from the launch area entry station and the filter rod empty box exit request from the molding area exit station, and to acquire the time for each group of empty boxes to be entered into the launch area entry station and the time consumed for each group of empty boxes at the molding area exit station.

[0170] The scheduling unit 720 is used to schedule the filter rod empty boxes based on at least one of the filter rod empty box inbound request and the filter rod empty box outbound request, the time for each group of empty boxes to be inbound at the launch area inbound station, and the time consumed by each group of empty boxes at the molding area outbound station. The scheduling of the filter rod empty boxes includes: binding the filter rod empty box outbound task and the filter rod empty box inbound task to generate a direct scheduling task for the stacker crane so that the stacker crane directly transports the filter rod empty boxes from the launch area inbound station to the molding area outbound station; or, generating an empty box inbound task for the stacker crane so that the stacker crane performs the filter rod empty box inbound operation, or generating an empty box outbound task for the stacker crane so that the stacker crane performs the filter rod empty box outbound operation.

[0171] Thus, a scheduling system for empty filter rod boxes according to some embodiments of this disclosure is provided. This can improve the system's flexible scheduling capability, increase the conveying efficiency of the filter rod storage, and reduce the time that empty boxes are occupied in the high-bay storage.
