Description

Technical Field

[0001] This invention relates to the field of automated logistics technology, specifically to a method for controlling the shipment of finished cigarette packages with multiple orders and sorting requirements. Background Technology

[0002] In the tobacco industry, the delivery of finished cigarette cartons not only needs to meet time constraints but also adhere to specific sequencing requirements to ensure that orders from different customers are delivered on time and in the correct order. Traditional delivery models involve a pallet of cigarettes leaving the warehouse via various conveying equipment such as stacker cranes, four-way vehicles, conveyors, and AGVs. This results in long transportation routes and extended transit times, leading to lengthy coordination between orders when multiple shipping manifests are processed through the same route. Furthermore, if each shipping manifest contains multiple brands and requires unloading at different locations, strict brand loading order is required during warehouse dispatch, further contributing to excessively long coordination times between different brand shipment details. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems by providing a method for controlling the shipment of finished cigarette packages with multiple orders and sorting requirements. This method is applicable to automated three-dimensional warehouses for finished products in the tobacco industry, reducing the connection time between orders and between shipment details within an order, and improving the shipment efficiency of finished cigarette packages.

[0004] The technical solution of the present invention is as follows:

[0005] A method for controlling the shipment of finished cigarette packages with multiple orders and sorting requirements, comprising the following steps:

[0006] Input parameters are taken from order management, platform management, buffer platform management, depalletizing platform management, and parameter settings.

[0007] In the comprehensive calculation management, the details of the current shipment documents, the details of the current inventory preparation documents, the available depalletizing stations for the documents, the available inventory preparation stations for the documents, and the relative distance between the stations are calculated separately to form an uninterrupted shipment control process and inventory preparation control process.

[0008] The shipment control process includes:

[0009] Retrieve documents in the "Confirmed" status at the current shipping platform, and retrieve details of documents that are currently being shipped out.

[0010] The available destacking stations are calculated based on the destacking stations corresponding to the platform.

[0011] Check if the cache station already has a pallet with goods prepared. If so, generate a task from the cache station to the depalletizing station. If not, check if there is a goods preparation task. If there is a goods preparation task, do not generate a task. Wait for the goods preparation task to be completed before generating a task from the cache station to the depalletizing station. If there is no goods preparation task, a task from the automated warehouse to the depalletizing station can be generated.

[0012] After the task at the depalletizing station is completed, the pallet is depalletized to complete the pallet shipping process.

[0013] Furthermore, the inventory control process includes:

[0014] Query the documents currently in the "confirmed" and "pre-confirmed" status at the platform and calculate the inventory preparation details;

[0015] Check if the cache station has a pallet for the document. If not, and there is no preparation task but there is an available depalletizing station, generate a task from the automated warehouse to the depalletizing station, and do not generate a preparation task.

[0016] If the cached station already has a prepared pallet or a prepared task, or if there is no available depalletizing station, then a prepared task is generated.

[0017] By setting parameters, the number of cacheable stations and the number of cached stations already occupied by the documents can be calculated to obtain the number of cached stations that can be stocked for the documents of the current platform.

[0018] Calculate the relative distance by the associated distance between the available buffer station and the corresponding depalletizing station of the platform, and sort them in ascending order of relative distance;

[0019] After the stockable caching stations are sorted by relative distance, tasks are generated from the automated warehouse to the caching stations.

[0020] Furthermore, the order management includes order status and order detail line attributes. Order status includes: new, pre-confirmed, confirmed, and completed; order detail line attributes include: shipping sequence, planned quantity, actual quantity, delisted quantity, and ready-to-stock quantity; the order management process includes:

[0021] Check if there are any documents in the "pre-confirmed" status in each shipping channel. If so, sort the documents in the "pre-confirmed" status in ascending order by time.

[0022] Check if there are any documents in the "Confirmed" status. If so, proceed with the shipment; otherwise, change the status of the first-ranked document in the "Pre-Confirmed" status to "Confirmed" and proceed with the shipment.

[0023] Furthermore, the platform management system sets the correspondence between platforms and depalletizing stations. After document confirmation, the target depalletizing station for generating outbound tasks is the depalletizing station corresponding to the platform.

[0024] Furthermore, both the cache station management and depalletizing station management include storage status and usage status. Storage status includes: idle, moved in, removed, and loaded; usage status includes: used and not used. The cache station and depalletizing station are set with associated distance according to the planar layout. The corresponding depalletizing stations of the same shipping platform are connected to each other. The associated distance of the depalletizing stations of the same shipping platform can be set to be the same. The associated distance is used to calculate the relative distance between the two stations.

[0025] Furthermore, the parameter settings include the current number of shipping platforms and the number of cache platforms. Based on the number of shipping platforms, the number of cache platforms that each shipping document can use is set.

[0026] Furthermore, the calculation of the current shipment document details includes: documents in the current "confirmed" status for each shipment channel, with document details ordered in ascending order by "shipping sequence", and detail rows where "planned quantity" is greater than "removed quantity";

[0027] The calculation of the current inventory preparation document details includes: document details in the "Confirmed" status are sorted in ascending order by "Shipping Order" to calculate the "Current Shipped Document Details". Then, it is checked whether there are any document details whose shipping order is after the "Current Shipped Document Details" and whose "Planned Quantity" is greater than the "Inventory Quantity". If so, this document detail is the "Current Inventory Preparation Document Details". Otherwise, the document details in the "Pre-Confirmed" status are queried, sorted in ascending order by "Shipping Order" and whose "Planned Quantity" is greater than the "Inventory Quantity" are the "Current Inventory Preparation Document Details".

[0028] Furthermore, the calculation of available depalletizing stations for the documents includes: finding the corresponding depalletizing station through the document platform, and filtering out depalletizing stations with a usage status of "in use" and a storage status of "idle".

[0029] Furthermore, the calculation document can be used at the preparation station, including:

[0030] Q: "Number of available stocking stations for the document";

[0031] The query filters out the "number of available storage stations" Q1 that are in use or idle;

[0032] Query the number of cached platforms currently occupied by shipping documents (Q2);

[0033] Query parameter settings to obtain the "Quantity of Goods Available for the Platform" for the current order shipment (Q3);

[0034] "Quantity available for stock preparation based on documents" Q4 = Q3 - Q2;

[0035] If Q4 <= 0, then Q = 0;

[0036] When Q4 > 0 and Q4 >= Q1, then Q = Q1;

[0037] When Q4 > 0 and Q4 < Q1, then Q = Q4.

[0038] Furthermore, the calculation of the relative distance between the platforms includes:

[0039] During the stock preparation stage, after querying the available buffer platforms, calculate the relative distance from the buffer platform to the depalletizing platform according to the associated distance between the depalletizing platform and the buffer platform, and sort them in ascending order according to the relative distance.

[0040] Compared with the existing technology, the beneficial effects of the present invention are:

[0041] A method for controlling the shipment of finished cigarette pieces with sorting requirements for multiple orders, which is used in the automated stereoscopic warehouse for finished products in the tobacco industry. In the case where the transportation path of the cigarette piece pallets to the shipping passage is long, there are many shipping orders, each order has many details, and the details within the order have strict shipping sequences, it reduces the connection time between orders and between the shipping details within the order, and improves the shipping efficiency of finished cigarette pieces.

[0049] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0050] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0051] Please see Figure 1-7 A method for controlling the shipment of finished cigarette packages with multiple orders and sorting requirements, such as... Figure 1 As shown, it includes the following steps:

[0052] Input parameters are taken from order management, platform management, buffer platform management, depalletizing platform management, and parameter settings.

[0053] In the comprehensive calculation management, the details of the current shipment documents, the details of the current inventory preparation documents, the available depalletizing stations for the documents, the available inventory preparation stations for the documents, and the relative distance between the stations are calculated separately to form an uninterrupted shipment control process and inventory preparation control process.

[0054] like Figure 6 As shown, the shipment control process includes:

[0055] Retrieve documents in the "Confirmed" status at the current shipping platform, and retrieve details of documents that are currently being shipped out.

[0056] The available destacking stations are calculated based on the destacking stations corresponding to the platform.

[0057] Check if the cache station already has a pallet with goods prepared. If so, generate a task from the cache station to the depalletizing station. If not, check if there is a goods preparation task. If there is a goods preparation task, do not generate a task. Wait for the goods preparation task to be completed before generating a task from the cache station to the depalletizing station. If there is no goods preparation task, a task from the automated warehouse to the depalletizing station can be generated.

[0058] After the task at the depalletizing station is completed, the pallet is depalletized to complete the pallet shipping process.

[0059] like Figure 7 As shown, the inventory control process includes:

[0060] Query the documents currently in the "confirmed" and "pre-confirmed" status at the platform and calculate the inventory preparation details;

[0061] Check if the cache station has a pallet for the document. If not, and there is no preparation task but there is an available depalletizing station, generate a task from the automated warehouse to the depalletizing station, and do not generate a preparation task.

[0062] If the cached station already has a prepared pallet or a prepared task, or if there is no available depalletizing station, then a prepared task is generated.

[0063] By setting parameters, the number of cacheable stations and the number of cached stations already occupied by the documents can be calculated to obtain the number of cached stations that can be stocked for the documents of the current platform.

[0064] Calculate the relative distance by the associated distance between the available buffer station and the corresponding depalletizing station of the platform, and sort them in ascending order of relative distance;

[0065] After the stockable caching stations are sorted by relative distance, tasks are generated from the automated warehouse to the caching stations.

[0066] Order management includes order status and order detail line attributes. Order status includes:

[0067] Added: Receive the initial status of documents created by external systems or manually;

[0068] Pre-confirmation: Waiting in the queue for shipment;

[0069] Confirmation: Shipment has commenced;

[0070] Completed: Shipment completed;

[0071] Order details line attributes include: Delivery sequence: the order in which materials are loaded onto the vehicle;

[0072] Planned quantity: The quantity of orders to be shipped;

[0073] Actual quantity: The actual quantity shipped;

[0074] Quantity removed from shelves: The quantity that has generated an outbound task but has not yet reached the shipping port;

[0075] Inventory quantity: The inventory quantity generated for the buffer station (if the task is generated directly for the depalletizing station, the inventory quantity in the document details after the task is generated needs to be added to the outbound quantity).

[0076] like Figure 2 As shown, the order management process includes:

[0077] Check if there are any documents in the "pre-confirmed" status in each shipping channel. If so, sort the documents in the "pre-confirmed" status in ascending order by time.

[0078] Check if there are any documents in the "Confirmed" status. If so, proceed with the shipment; otherwise, change the status of the first-ranked document in the "Pre-Confirmed" status to "Confirmed" and proceed with the shipment.

[0079] The platform management system sets up a correspondence between platforms and depalletizing stations. After document confirmation, the target depalletizing station for generating outbound tasks is the depalletizing station corresponding to the platform.

[0080] Both cache station management and depalletizing station management include storage status and usage status. Storage status includes:

[0081] Idle: The current platform is idle;

[0082] Move In: There is a task to move a pallet to the current platform;

[0083] Remove: The task of moving the pallet from the current platform to another location;

[0084] Cargo loading: The platform is currently occupied by pallets;

[0085] Usage status includes: in use and not in use;

[0086] The associated distance between the buffer station and the depalletizing station is set according to the floor plan. The corresponding depalletizing stations of the same shipping platform are connected to each other. The associated distance between the depalletizing stations of the same shipping platform can be set to the same. The associated distance is used to calculate the relative distance between the two stations.

[0087] The parameter settings include the current number of shipping platforms and the number of cached platforms. Based on the number of shipping platforms, the number of cached platforms that can be used for each shipping document can be set.

[0088] The current shipment document details include: documents in the current "confirmed" status for each shipment channel, with document details sorted in ascending order by "shipping sequence", and detail rows where "planned quantity" is greater than "removed quantity";

[0089] The calculation of the current inventory preparation document details includes: document details in the "Confirmed" status are sorted in ascending order by "Shipping Order" to calculate the "Current Shipped Document Details". Then, it is checked whether there are any document details whose shipping order is after the "Current Shipped Document Details" and whose "Planned Quantity" is greater than the "Inventory Quantity". If so, this document detail is the "Current Inventory Preparation Document Details". Otherwise, the document details in the "Pre-Confirmed" status are queried, sorted in ascending order by "Shipping Order" and whose "Planned Quantity" is greater than the "Inventory Quantity" are the "Current Inventory Preparation Document Details".

[0090] The available depalletizing stations for the documents are calculated as follows: the corresponding depalletizing stations are found through the document platform, and depalletizing stations with a usage status of "in use" and a storage status of "idle" are filtered out.

[0091] The available stock preparation platforms for calculation documents include:

[0092] "Quantity of available stock preparation platforms for documents" Q;

[0093] Query and filter out "Quantity of available stock preparation platforms" Q1 with the usage status of "In use" and the storage status of "Idle";

[0094] Query the "Quantity of buffer platforms occupied by shipping documents" Q2 of the current platform;

[0095] Query the parameter settings to obtain the "Quantity of available stock preparation on the platform" Q3 for the current document shipment;

[0096] "Quantity of available stock preparation for documents" Q4 = Q3 - Q2;

[0097] When Q4 <= 0, then Q = 0;

[0098] When Q4 > 0 and Q4 >= Q1, then Q = Q1;

[0099] When Q4 > 0 and Q4 < Q1, then Q = Q4.

[0100] Calculating the relative distance of platforms includes:

[0101] After querying the available buffer platforms during the stock preparation stage, according to the associated distance between the depalletizing platform and the buffer platform, calculate the relative distance from the buffer platform to the depalletizing platform, and sort it in ascending order according to the relative distance.

[0102] In another specific embodiment, as Figure 3 shown, the first floor includes a four-way vehicle automated storage and retrieval system, 28 buffer platforms, 5 robotic arms, 6 depalletizing channels, and 15 depalletizing platforms, and 5 sorting and shipping platforms; Figure 4 Shown are the dense warehouses with the same layout on the second, third, and fourth floors. These floors use elevators to achieve pallet handling between different floors. Each floor uses AGVs to achieve pallet handling between platforms.

[0103] It can be analyzed from the floor plan that the pallets in the four-way garage on the first floor need to be transported by four-way vehicles, conveyors, and AGVs from the automated storage and retrieval system to the depalletizing platform for depalletizing. The pallets in the dense warehouses on the second, third, and fourth floors need to be transported by AGVs, floor elevators, and AGVs from the automated storage and retrieval system to the depalletizing platform; the time for pallets to reach the depalletizing platform is relatively long, especially for the second, third, and fourth floors. If shipping is done one document at a time, it will cause too long connection time between document details and between documents, seriously affecting the shipping efficiency.

[0104] This method fully utilizes the cache station through the "input parameters" and "comprehensive calculation management" in the technical solution to achieve seamless connection between document details and between documents, thereby improving the efficiency of cigarette sorting and delivery.

[0105] Relevant correspondences and parameter settings:

[0106] Correspondence between platforms and destacking platforms:

[0107] A corresponding relationship can be set between a shipping platform and the depalletizing station of the robot arm located in the depalletizing channel connected to the logistics path. The corresponding relationship between the shipping platform and which depalletizing stations can be set according to the shipping needs.

[0108] For example Figure 3 The top shipping channel #1 can be bound to three depalletizing stations of robot #1 and three depalletizing stations of robot #2. The actual setting is that shipping channel #1 is bound to three depalletizing stations of robot #1 and one depalletizing station of robot #2.

[0109] Association distance settings;

[0110] The associated distance of the destacking station is according to Figure 3 From top to bottom, the distance between the three depalletizing stations of robot arm 1 is 1, that of robot arm 2 is 2, and so on.

[0111] The association distance of cached sites, set from top to bottom and from right to left, is as follows: Figure 5 As shown,

[0112] Current shipping platform quantity and buffer platform quantity settings:

[0113] Based on the actual situation, the maximum number of platforms that can ship goods at the same time is 3, and the parameters are set as follows.

[0114] One platform can handle shipments, and the platform has a cacheable number of 12 stations.

[0115] Two platforms are used for shipping, and the number of platforms that can be cached is 12.

[0116] For shipments made from 3 or more platforms, the number of platforms that can be buffered is 10.

[0117] Usage status settings for the cache / depalletizing station.

[0118] The usage status of a station can be set based on its specific fault status, or the usage status of a station can be manually set.

[0119] like Figure 6 As shown, the shipment control process includes:

[0120] Retrieve documents in the "Confirmed" status at the current shipping platform, and retrieve details of documents that are currently being shipped out.

[0121] The available destacking stations are calculated based on the destacking stations corresponding to the platform.

[0122] Check if the cache station already has a pallet with goods prepared. If so, generate a task from the cache station to the depalletizing station. If not, check if there is a goods preparation task. If there is a goods preparation task, do not generate a task. Wait for the goods preparation task to be completed before generating a task from the cache station to the depalletizing station. If there is no goods preparation task, a task from the automated warehouse to the depalletizing station can be generated.

[0123] After the task at the depalletizing station is completed, the pallet is depalletized to complete the pallet shipping process.

[0124] like Figure 7 As shown, the inventory control process includes:

[0125] Query the documents currently in the "confirmed" and "pre-confirmed" status at the platform and calculate the inventory preparation details;

[0126] Check if the cache station has a pallet for the document. If not, and there is no preparation task but there is an available depalletizing station, generate a task from the automated warehouse to the depalletizing station, and do not generate a preparation task.

[0127] If the cached station already has a prepared pallet or a prepared task, or if there is no available depalletizing station, then a prepared task is generated.

[0128] By setting parameters, the number of cacheable stations and the number of cached stations already occupied by the documents can be calculated to obtain the number of cached stations that can be stocked for the documents of the current platform.

[0129] Calculate the relative distance by the associated distance between the available buffer station and the corresponding depalletizing station of the platform, and sort them in ascending order of relative distance;

[0130] After the stockable caching stations are sorted by relative distance, tasks are generated from the automated warehouse to the caching stations.

[0131] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
