Description

Technical Field

[0001] The present invention relates to the technical field of warehousing cigarette auxiliary materials, and more specifically, to a method and system for warehousing single-variety cigarette auxiliary materials. Background Art

[0002] At present, the storage of single-variety auxiliary materials in some cigarette factories in the tobacco industry is mainly done manually. First, it is necessary to manually drive a forklift close to the truck and move the single-variety auxiliary materials on the truck to the auxiliary material storage platform. In this process, factors such as the proficiency of manual forklift operation and the accuracy of operation will affect the handling efficiency and safety. Then, the forklift is manually driven again to transfer the auxiliary materials temporarily stored on the platform to the location designated by the custodian in the warehouse for storage. When transporting inside the warehouse, due to factors such as warehouse layout and shelf location, manual labor needs to rely on experience and familiarity with the warehouse environment to determine the driving route and placement location, which may lead to less optimized path selection and increase the handling time and forklift energy consumption. For key information such as the brand and quantity of auxiliary materials, it is completely dependent on manual verification, statistics and recording. The staff needs to check the packaging label of the auxiliary materials to determine the brand, and then count the quantity one by one. In this process, it is easy to be interfered by human factors.

[0003] The entire warehousing process almost relies on manual operation, lacking the intervention of automated equipment and systems. It is impossible to achieve 24-hour uninterrupted operation, and the operation speed is relatively slow, which limits the overall efficiency of warehousing. Due to manual verification of statistical data, the accuracy of the data is difficult to guarantee. Once the data statistics are wrong, it will have a chain reaction on subsequent production planning, inventory management and other links. For example, if the number of auxiliary materials is counted incorrectly, it may lead to a shortage of auxiliary materials in the production process, affecting the progress of cigarette production; or inaccurate inventory data makes it impossible for enterprises to accurately grasp the inventory level, affecting procurement decisions and cost control. Summary of the invention

[0004] One purpose of the present invention is to provide a method and system for warehousing single-variety cigarette auxiliary materials to solve the aforementioned problems of being unable to achieve 24-hour uninterrupted operation, relatively slow operation speed, difficulty in ensuring data accuracy, and affecting procurement decisions and cost control.

[0005] According to a first aspect of the present invention, a method for warehousing single-variety auxiliary materials of cigarettes is provided, comprising the following steps:

[0006] Step 1: Move the single-variety auxiliary materials from the auxiliary materials storage platform to the empty pallet at the storage receiving station;

[0007] Step 2: Use the RFID reader to identify the information of a single variety of auxiliary materials, associate it with the empty pallet, and enter it into the warehouse management system;

[0008] Step 3: When a certain storage receiving station is empty, the empty pallets that have been split from the pallet splitter are moved and added to the storage receiving station;

[0009] Step 4: The warehouse management system automatically calculates and allocates cargo locations, and the latent AGV transports the single-variety auxiliary material pallet to the designated location in the single-variety auxiliary material storage area for storage. After the warehouse management system receives the confirmation signal that the transportation task is completed, it updates the internal cargo location database in real time.

[0010] Optionally, after step 4, a random inspection step is further included, and the random inspection step includes:

[0011] Obtaining sampling information, including but not limited to the type of sampled auxiliary materials, supplier name, storage time of the sampled auxiliary materials, and the number of samples sampled;

[0012] Automatically allocate a sampling inspection location based on the sampling inspection information, and use the latent AGV to take out the auxiliary material pallet from the sampling inspection location and transport it to the sampling inspection station;

[0013] Judge based on the test result notification. If the sampling result is normal, the products will be officially put into storage, and the batch of auxiliary materials will be unlocked and arranged for delivery from the warehouse.

[0014] Optionally, before step 1, the method further includes:

[0015] Unload single-variety auxiliary materials to the auxiliary materials storage platform according to the storage plan;

[0016] Single-variety auxiliary materials will be counted and preliminarily inspected, and those that fail the count and preliminarily inspection will be rejected and returned.

[0017] Optionally, in step 3, after the latent AGV takes away the last empty pallet from the pallet splitter, a group of empty pallet groups is transported from the empty pallet group temporary storage area to the pallet splitter.

[0018] Optionally, in step 3, the number of empty pallets currently split is monitored and recorded in real time by the pallet splitter. When the number of empty pallets reaches below a preset threshold, the pallet splitter automatically sends a replenishment signal to the latent AGV. The replenishment signal includes but is not limited to information on insufficient number of empty pallets, the number of empty pallets that need to be replenished, and replenishment location information.

[0019] Optionally, in step 4, the warehouse management system locks the auxiliary materials after they are put into storage but before they are officially put into storage, so that the auxiliary materials of this batch cannot be used for palletizing, outbound transportation or any other operation temporarily.

[0020] Optionally, in step 4, the warehouse management system automatically calculates and allocates storage space by comprehensively considering the category, quantity, storage requirements of the single-variety auxiliary materials and the current usage of the storage space in the warehouse.

[0021] According to the second aspect of the present invention, a cigarette single-variety auxiliary material warehousing system is provided, comprising an auxiliary material warehousing platform, a forklift AGV, a lurking AGV, a pallet splitter and an RFID reader / writer, wherein the single-variety auxiliary material is transported from the auxiliary material warehousing platform to an empty pallet at an incoming warehousing receiving station by the forklift AGV, the single-variety auxiliary material information is identified by the RFID reader / writer, associated and bound with the empty pallet, and entered into a warehouse management system; when a certain incoming warehousing receiving station is empty, the lurking AGV takes the split empty pallet from the pallet splitter and replenishes it to the incoming warehousing receiving station; the warehouse management system automatically calculates and allocates cargo locations, and the lurking AGV transports the single-variety auxiliary material pallet to a designated location in the single-variety auxiliary material storage area for storage, and updates the cargo location information in real time.

[0022] The method and system for warehousing single-variety cigarette auxiliary materials disclosed in the present invention have the following technical effects:

[0023] There are various single-variety auxiliary materials on the auxiliary material storage platform of the present invention. The forklift AGV lifts these auxiliary materials smoothly through its own mechanical structure and transports them to the empty pallets prepared in advance at the storage receiving station. The name, specification, batch, production date and other information of the single-variety auxiliary materials are bound to the unique identification of the pallet to form a data association relationship. After the auxiliary material information is bound to the pallet, it is synchronized to the warehouse management system, and then the lurking AGV transports the auxiliary material pallet at the storage receiving station to the single-variety auxiliary material storage area automatically allocated by the system, and is officially put into storage after passing the random inspection.

[0024] The entire process is completed by forklift AGV and lurking AGV, which reduces the dependence on manual forklift drivers and porters, and realizes the automated handling process from the auxiliary material storage platform to the storage area. It not only improves work efficiency, but also can operate stably in some harsh environments (such as high temperature, low temperature, toxic and harmful, etc.) or high-intensity labor scenes.

[0025] By binding auxiliary material information with pallets and synchronizing them to the warehouse management system, real-time update and accurate management of inventory information is achieved. Enterprises can grasp information such as inventory quantity, location, quality status, etc. at any time, avoiding errors and data lags that may occur in manual recording.

[0026] The sampling inspection link is closely integrated with the entire warehousing process, which can timely detect and deal with unqualified auxiliary materials and prevent unqualified products from being mixed into inventory, thereby ensuring the quality stability of auxiliary materials used in the company's production.

[0027] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] The present invention proposes an embodiment of a method for storing a single type of cigarette auxiliary materials. Specifically, Figure 1 As shown, the following steps are included:

[0038] Step 1: Move the single-variety auxiliary materials from the auxiliary materials storage platform to the empty pallet at the storage receiving station; various single-variety auxiliary materials such as paper, filter materials, etc., use forklifts, AGVs and other automated handling equipment to accurately move the single-variety auxiliary materials from the platform and place them on the empty pallet prepared in advance at the storage receiving station.

[0039] Step 2: Use the RFID (Radio Frequency Identification) reader to identify the information of a single variety of auxiliary materials, associate it with an empty pallet, and enter it into the warehouse management system (WMS); when a single variety of auxiliary materials is placed on a pallet, the RFID reader will emit a radio frequency signal to read the RFID tag information attached to the auxiliary material packaging. The RFID tag information includes the detailed name of the auxiliary material, specification model, production batch, supplier information, etc. The auxiliary material information is associated and bound with the pallet information through the system software to form a complete logistics data unit. Afterwards, these bound data are accurately entered into the warehouse management system (WMS) through a wired or wireless data transmission network, avoiding the errors and inefficiencies that may occur when manually scanning and entering the code one by one.

[0040] Step 3: When a certain warehouse receiving station is empty, the empty pallets split from the pallet splitter are moved and added to the warehouse receiving station; the pallet splitter splits the whole stack of empty pallets for the transportation and use of individual pallets. The latent AGV moves the split empty pallets from the pallet splitter and adds them to the empty warehouse receiving station along the preset path. This ensures that there are always available empty pallets at the warehouse receiving station, so that the entire warehouse process can be carried out continuously and efficiently.

[0041] Step 4: The warehouse management system automatically calculates and allocates cargo locations, and the latent AGV moves the single-variety auxiliary material pallet to the designated location in the single-variety auxiliary material storage area for storage. After the warehouse management system receives the confirmation signal of the completion of the handling task, it updates the internal cargo location database in real time. Specifically, the warehouse management system automatically calculates and allocates the most suitable cargo location to the single-variety auxiliary material pallet that is about to enter the warehouse based on the warehouse layout, inventory status and preset storage strategies (such as factors such as the type of auxiliary materials, frequency of entry and exit, and shelf life), generates a single-variety auxiliary material entry task, including the warehouse receiving station for picking up goods, the brand and quantity of auxiliary materials, and the location of the single-variety auxiliary material storage area for releasing goods. The task information is forwarded to the warehouse control system, and the warehouse control system issues instructions to the latent AGV. After receiving the system instructions, the latent AGV lifts the pallet from the warehouse receiving station and moves it to the designated single-variety auxiliary material storage area. When the latent AGV arrives at the designated cargo location and completes the placement of the pallet, it will send a confirmation signal to the warehouse management system to complete the handling task. After receiving the confirmation signal, the warehouse management system immediately updates the internal cargo location database in real time and accurately records the current location information of the pallet so that subsequent inventory query, inventory counting, outbound delivery and other operations can proceed smoothly.

[0042] The entire warehousing process, from the platform to the warehousing receiving station and then to the single-variety auxiliary material storage area, is completed by a variety of automated equipment (AGV, pallet splitter, etc.), reducing manual intervention and realizing the automation and intelligence of the logistics process.

[0043] In the embodiment of the present invention, a sampling step is further included after step 4, and the sampling step includes:

[0044] Obtain sampling information, which includes but is not limited to the type of sampling auxiliary materials, supplier name, storage area time of the single type auxiliary materials, and sampling quantity; for large quantities of cigarette packaging paper auxiliary materials, a certain number of samples are taken for testing according to a certain ratio (such as one thousandth or one ten-thousandth), and the sampling information is stored in the quality inspection management system, or is associated with the warehouse management system.

[0045] Based on the sampling information, the sampling location is automatically allocated, and the latent AGV goes to the sampling location to take out the auxiliary material pallet and transport it to the sampling station 7; specifically, based on the sampling information, the location where the auxiliary material pallet that needs to be sampled is located is automatically determined in the warehouse management system, and the warehouse layout, storage status of the location, and the current operation of the latent AGV are comprehensively considered in the process of automatic allocation of the location. For example, if there are multiple pallets of the same type of auxiliary materials distributed in different locations, the location that is closer to the current location of the latent AGV or located in a more convenient position in the passage will be given priority to improve the handling efficiency. Then, after receiving the instruction, the latent AGV will accurately drive to the designated sampling location based on its built-in navigation system and map information.

[0046] According to the test result notification, if the sampling results are normal, the auxiliary materials will be officially put into storage, and the batch of auxiliary materials will be unlocked and arranged for pallet delivery. The sampling results include but are not limited to the strength, thickness uniformity, and appearance quality of the paper. If the sampling results are normal, the auxiliary materials can be officially put into storage. In the warehouse management system, the status of the batch of auxiliary materials will be updated to the formal storage status. At the same time, the restrictions set by the sampling inspection (such as locking the inventory and not being able to be used for pallet delivery) will be lifted, that is, the batch of auxiliary materials will be unlocked. Then, the system will arrange for the pallet delivery according to production needs. For example, according to the requirements of the cigarette production order, different varieties of auxiliary materials will be combined into pallets for supply to the production line. If the sampling results are abnormal, the corresponding unqualified product processing process will be initiated, including isolating unqualified auxiliary materials, notifying suppliers to return and exchange goods, and expanding sampling of other auxiliary materials in the same batch, etc., to ensure that unqualified auxiliary materials will not be put into cigarette production and ensure product quality.

[0047] In the embodiment of the present invention, before step 1, it also includes: unloading the single-variety auxiliary materials to the auxiliary material storage platform according to the storage plan; counting and preliminarily inspecting the single-variety auxiliary materials, and rejecting and returning the single-variety auxiliary materials that fail the counting and preliminarily inspection.

[0048] In the embodiment of the present invention, in step 3, after the latent AGV takes the last empty pallet from the pallet splitter, a group of empty pallet groups is transported from the empty pallet group temporary storage area to the pallet splitter. It should be noted that during the storage of cigarette auxiliary materials, if there are not enough empty pallets, the single-variety auxiliary materials transported from the auxiliary material storage platform will not be placed on a suitable pallet for subsequent information binding and storage operations. Set 5 or 10 empty pallets to form a group.

[0049] It should be noted that after the latent AGV takes the last empty pallet from the pallet splitter, the electronic control system sends a signal to the warehouse management system, the warehouse management system generates a task to replenish the empty pallet group and sends it to the warehouse control system, the warehouse control system issues instructions to the latent AGV, dispatching the latent AGV to the empty pallet group temporary storage area to transport a group of empty pallets and replenish them to the pallet splitter.

[0050] In an embodiment of the present invention, in step 3, the number of empty pallets currently split is monitored and recorded in real time by the pallet splitter. When the number of empty pallets reaches below the preset threshold, the pallet splitter automatically sends a supplementary signal to the latent AGV, and the supplementary signal includes but is not limited to information about the insufficient number of empty pallets, the number of empty pallets that need to be supplemented, and the supplementary position information. Specifically, in the cigarette auxiliary material warehouse, the pallet splitter uses a photoelectric sensor. When the empty pallet is separated from the whole stack and passes through a specific detection area, the photoelectric sensor generates a signal, and the control system of the pallet splitter processes and counts these signals, so as to grasp the number of empty pallets that have been split in real time. When the pallet splitter monitors that the number of empty pallets currently split reaches below this preset threshold, the supplement mechanism will be automatically triggered. For example, if the preset threshold is set to 10 empty pallets, when only 5 empty pallets are left after the splitter is split, the supplementary condition is met. At this time, the pallet splitter automatically sends a supplementary signal to the latent AGV. The signal transmission between the pallet splitter and the latent AGV is carried out through a wireless communication network, and the wireless communication network can be built based on Wi-Fi, Bluetooth or a special industrial Internet of Things communication protocol. Through real-time monitoring of the pallet splitter and the setting of preset thresholds, precise control of empty pallet inventory is achieved. The automatic signal interaction and collaborative operation between the pallet splitter and the latent AGV greatly improves the efficiency of warehouse logistics operations.

[0051] In an embodiment of the present invention, in step 4, the warehouse management system locks the auxiliary materials after they are put into storage and before they are formally put into storage, so that the auxiliary materials of this batch cannot be used for pallet distribution or any other operation temporarily. It should be noted that in the cigarette auxiliary materials warehouse, although a batch of newly arrived paper auxiliary materials has been placed in the designated cargo position, due to the need for subsequent processes such as random inspection, the warehouse management system will set a specific locking mark for this batch of auxiliary materials in the database at this time. This locking mark will be associated with all information records of this batch of auxiliary materials, including its cargo position, quantity, variety and other information. The locked auxiliary materials cannot be used for pallet distribution temporarily, that is, when there is a cigarette production order on the production line that requires auxiliary materials to be distributed, the auxiliary materials in the locked state are automatically skipped and will not be included in the optional range of distribution. By locking the auxiliary materials before they are formally put into storage, the unverified auxiliary materials are effectively isolated from the production link. Unqualified auxiliary materials are prevented from entering the production process, thereby ensuring the quality stability of cigarette products.

[0052] In the embodiment of the present invention, in step 4, the warehouse management system automatically calculates and allocates cargo spaces, taking into account the category, quantity, storage requirements of the single-variety auxiliary materials, and the current usage of the cargo spaces in the warehouse. Among them, the cargo spaces are accurately allocated according to the category and storage requirements of the auxiliary materials, creating a suitable storage environment for various auxiliary materials, effectively reducing the occurrence of deterioration and damage of auxiliary materials caused by poor storage conditions. The location is allocated considering the quantity of auxiliary materials and the current usage of the cargo spaces, so that the auxiliary materials can be quickly and accurately placed in the appropriate cargo spaces when entering the warehouse, reducing the detours and confusion of transportation.

[0053] The present invention also provides an embodiment of a system for storing single-variety auxiliary materials of cigarettes, such as Figure 2 As shown, it includes an auxiliary material storage platform 1, a forklift AGV 2, a latent AGV 4, a pallet splitter 5 and an RFID reader / writer, wherein the forklift AGV transports the single-variety auxiliary material from the auxiliary material storage platform 1 to the empty pallet at the storage receiving station 3, and the RFID reader / writer identifies the single-variety auxiliary material information, associates and binds it with the empty pallet in the empty pallet group temporary storage area 8, and enters it into the warehouse management system; when a certain storage receiving station is empty, the latent AGV takes the split empty pallet from the pallet splitter 5 and replenishes it to the storage receiving station 3; the warehouse management system automatically calculates and allocates the cargo location, and the latent AGV4 transports the single-variety auxiliary material pallet to the designated position of the single-variety auxiliary material storage area 6 for storage, and updates the cargo location information in real time.

[0054] It should be noted that the information interaction, execution process and other contents between the above-mentioned devices are based on the same concept as the method embodiment of the present application, and are devices corresponding to the above-mentioned method for storing single-variety auxiliary materials of cigarettes. All implementation methods in the above-mentioned method embodiment are applicable to the embodiment of the device. Its specific functions and technical effects brought about can be found in the method embodiment part, which will not be repeated here.

[0055] The entire cigarette single-variety auxiliary material storage system integrates automated equipment such as forklift AGV and lurking AGV, realizing the automated handling of auxiliary materials from their initial position on the storage platform to their final storage in the single-variety auxiliary material storage area. When there is a vacancy at the storage receiving station, the lurking AGV can automatically take the split empty pallets from the pallet splitter to replenish them, ensuring that there are always available pallets at the storage receiving station, so that the auxiliary material handling process will not be interrupted due to pallet shortages. The RFID reader is used to identify the information of single-variety auxiliary materials, and then associated and bound with the empty pallets and entered into the warehouse management system, avoiding possible errors in manual information recording. The inventory location data stored in the system is always the latest, and warehouse managers can efficiently perform inventory counting, search for specific auxiliary materials, and arrange outbound operations based on accurate cargo location information, reducing management confusion and operation delays caused by inaccurate cargo location information, and improving the overall accuracy of warehouse management. Through intelligent cargo location allocation, unreasonable occupation and waste of warehouse space can be avoided. When facing the demand for auxiliary material storage in different time periods and different scales, the system can flexibly adjust its operation.

[0056] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
