Description

Technical Field

[0001] The invention relates to a raw cigarette proportioning packaging and formula library logistics system and a transportation method, belonging to the technical field of logistics. Background Art

[0002] The traditional redrying raw tobacco formula work adopts a direct feeding mode of manual leaf laying and mixing, which is rigidly connected to the leaf threshing and redrying production section. Leaf laying and feeding are carried out simultaneously with leaf threshing and redrying, resulting in long working hours and high labor intensity for workers in the material preparation section. After laying the leaves, there is no packing system and formula library logistics system. The tobacco leaves are not stored in tobacco boxes as units, chemical value balance cannot be achieved, formula management and scheduling are difficult, production efficiency is low, and it is not easy to achieve flexible and fine formula leaf threshing production. In addition, due to the simple routes and single functions of the existing high-rise warehouses, there is no efficient processing mechanism for equipment failures and calibration anomalies. It is impossible to ensure that the order of tobacco boxes leaving the warehouse remains unchanged and the accuracy of the tobacco leaf formula ratio cannot be ensured. It is mostly used as a temporary storage warehouse, which loses the function of formula production and homogenization processing of the high-rise warehouse.

[0003] Therefore, a raw cigarette proportioning packaging and formula library logistics system and transportation method are proposed. Through the raw cigarette proportioning packaging system, formula library logistics system and formula library logistics transportation method, the production batch is guaranteed to meet the formula and homogenization requirements, and the efficiency of cigarette box transportation is improved. Summary of the Invention

[0004] In order to overcome the problems existing in the background technology, the present invention completes the production tasks such as raw cigarette proportioning and packing, formula outbound feeding, vacuum rehumidification processing, and direct delivery from the warehouse through the raw cigarette proportioning and packing system, the formula warehouse logistics system and the formula warehouse logistics transportation method. It has multiple processing modes such as multi-grade formula processing of raw cigarettes, offline cutting of raw cigarettes, single-grade raw cigarette warehousing and formula outbound delivery, improves the degree of automation of raw cigarette proportioning and packing and formula warehouse logistics transportation, and improves the efficiency of cigarette box transportation.

[0005] In order to overcome the problems existing in the background technology and solve the above problems, the present invention is implemented through the following technical solutions:

[0006] The raw cigarette proportioning and packing system comprises an empty box buffer line, a packing station, a belt conveyor, a dual-channel slitting machine, a leaf laying line, and a cigarette box conveying line. The leaf laying line is connected to the feed port of the dual-channel slitting machine, and the discharge port of the dual-channel slitting machine is connected to the packing station via a belt conveyor. The empty box buffer line is arranged at the front end below the packing station, and the cigarette box conveying line is arranged at the rear end below the packing station. The cigarette box conveying line is connected to the formula three-dimensional warehouse.

[0007] The formula warehouse logistics system includes a box turning and feeding area, a manual processing area, an initialization loading and unloading platform, a formula three-dimensional warehouse, a vertical conveyor, a cache station, a vacuum rehumidification machine, and a return warehouse route. The vertical conveyor is installed at the front end of the formula three-dimensional warehouse and is used to lift and transport cigarette boxes to solve the problem of terrain height. The cigarette box conveyor line is connected to the vertical conveyor. Four cigarette box conveyor lines are set at the front end of the formula three-dimensional warehouse, two of which are connected to the vacuum rehumidification machine, and the other two conveyor lines are connected to the return warehouse route. Cache stations are set at the front and rear ends of the vacuum rehumidification machine. The cache station at the rear end of the vacuum rehumidification machine is connected to the box turning and feeding area. A cache station is also set in front of the box turning and feeding area. A return warehouse route is set in the box turning and feeding area. The return warehouse route is connected to the empty box cache line and the conveyor line of the formula three-dimensional warehouse respectively. The return warehouse route is provided with an initialization loading and unloading platform for loading and unloading empty cigarette boxes. A manual processing area for handling abnormal cigarette boxes is set next to the initialization loading and unloading platform.

[0008] Preferably, a scanning and detection device is provided at the outlet of the vertical conveyor at the front end of the formula stereoscopic warehouse. The scanning and detection device includes an RFID scanner and a camera, which can read and write RFID chips and scan and identify the QR codes of cigarette boxes to verify the information of cigarette boxes; a scanning and detection device is also provided at the front end buffer station of the box turning feeding area to check the information of cigarette boxes again; a weighing detection device is provided at the connection between the return route and the empty box cleaning platform. The weighing detection device includes a weighing sensor and a camera to detect whether there are any tobacco leaves remaining in the empty box.

[0009] Preferably, the formula three-dimensional warehouse includes two levels of entry and exit platforms, the first level is for full box entry, empty box entry and exit, and queue-jumping full box exit, and the second level is for full box exit.

[0010] A method for packing raw cigarettes into boxes and transporting them from a formula library comprises the following steps:

[0011] S1. When the system is first put into production, the control system is initialized, the basic RFID information and box number of the empty box are written, and the box is transported to the formula storage system for storage;

[0012] S2. Process the tobacco leaves before packing and transfer the empty boxes to the empty box cache line according to the system planning order to wait for packing;

[0013] S3. The tobacco leaves are packed into boxes, their information is written, and the leaves are transported via the box conveyor line to the first-floor loading station of the formula warehouse. A check is performed to determine whether the leaves will be loaded into the warehouse from another warehouse. If not, they are directly loaded into the warehouse for storage. If they are loaded into another warehouse from another warehouse, they are transported to a vacuum rehumidifier or a box feeding area.

[0014] S4. Based on the delivery strategy generated by the proportion packing and homogenization formula management system, the aisle stacker crane retrieves the cigarette case from the designated location and transports it to the front conveyor channel of the formula three-dimensional warehouse via the second-level delivery platform and the vertical conveyor in the order required by the delivery strategy. Before delivery, the RFID information is checked at the conveyor channel of the vertical conveyor exit. If the check passes, the cigarette case is transported to the vacuum rehumidification machine or directly to the buffer station in the box turning feeding area. If the information is incorrect, the delivery is stopped and the correct cigarette case is transferred from the vertical conveyor at the empty box inlet of the formula three-dimensional warehouse to jump the queue. The incorrect cigarette case is returned to the inlet channel.

[0015] S5. Vacuum conditioning: The tobacco boxes shipped from the formula storage are sent to the buffer station in front of the vacuum conditioning machine, waiting to enter the conditioning machine for processing. The vacuum conditioning-completed tobacco boxes are sent to the corresponding buffer station in the feeding area via the conveyor system.

[0016] S6. Cigarette cases that do not require vacuum conditioning are directly delivered by the conveyor system to the corresponding buffer station in the box turning and feeding area;

[0017] S7. When cigarette cases are at the buffer station in the case-turning feeding area, the RFID information is secondary checked. If the check is correct, the case-turning feeder will turn the cigarette case into the feeder for production use. If an abnormal cigarette case is secondary detected, the system stops the case-turning feeding, analyzes the error, and takes appropriate measures.

[0018] S8. After the empty boxes are turned over and fed, they are processed and returned via the return route. During the return transport, they undergo inspection. Empty boxes that pass the inspection and are clean are first sent to the buffer station in front of the packing station for packing. Empty boxes that fail the inspection are sent to the manual cleaning station and, after cleaning, are returned for re-inspection.

[0019] S9. Empty boxes on the empty box buffer line are returned to the warehouse in a centralized manner. When production is completed, the empty boxes on the empty box buffer line and the buffer stations in the packing area can be collectively transported to the formula three-dimensional warehouse for storage through the cigarette box conveyor line.

[0020] Preferably, the S2 and S8 empty boxes are first mobilized from the return route to reduce the in-and-out flow of empty boxes. When the empty box buffer station is full, they are stored in the formula three-dimensional warehouse. When the system flow cannot be met during the peak production period, empty cigarette boxes are then mobilized from the formula three-dimensional warehouse.

[0021] Preferably, before the S3 tobacco leaves are packed, the empty boxes are weighed and image inspected again before entering the packing station. If an abnormality is detected, the empty boxes will not be packed. After being marked, they will be transported to the abnormality processing station for processing, and empty boxes will be mobilized for replenishment. After the packing is completed, the full boxes enter the information writing station, and the tobacco grade, batch, weight, specification, time, and chemical composition value information are written into the RFID and then put into storage.

[0022] Preferably, the S4 detects an abnormal smoke box in the following situations:

[0023] S4.1, if the RFID information cannot be read, but the box number information on the nameplate is consistent with the system prompt, mark the abnormal cigarette box and resume transportation. After the box turning and feeding are completed, it will be transported to the manual station for RFID replacement and then put into storage, or put into storage first and then shipped out for replacement;

[0024] S4.2, if the box number information on the RFID is inconsistent with the system prompt, but the box number information on the nameplate is consistent with the system prompt, the abnormal cigarette box will be marked and the conveying will be resumed. After the box turning and feeding are completed, it will be conveyed to the manual station for RFID information update and then put into storage;

[0025] S4.3: When the box number information detected by RFID is consistent with the nameplate, but inconsistent with the information of the cigarette boxes of the batch to be shipped prompted by the system, it is a shipping error. After recalculation, the system immediately calls out the required cigarette boxes from the warehouse through the vertical conveyor at the empty box entrance on the first floor of the formula three-dimensional warehouse. After inserting it to the original position of the abnormal cigarette box through the conveying channel, the vertical conveyor resumes the conveyance of the next cigarette box to ensure that the shipment of this batch meets the formula and homogenization requirements. The cigarette boxes with incorrect shipment are returned to the warehouse to update the inventory information and re-added to the calculation queue to ensure that the shipment of subsequent batches meets the formula and homogenization requirements.

[0026] Preferably, when the S7 detects an abnormal cigarette box for the second time, when it is detected that the RFID information cannot be read and the box number information of the RFID is inconsistent with the system prompt but the box number information on the nameplate is consistent with the system prompt, the processing is the same as S4.1 and S4.2. When an outbound error is detected, the system will recalculate and immediately call out the required cigarette box from the warehouse and take it off the line from the initialization up and down line platform. The correct cigarette box will be transported to the up-line platform of the box turning feeding area by a forklift, and then inserted into the position of the original wrong cigarette box and the box turning feeding will be resumed to ensure that the outbound of this batch meets the formula and homogenization requirements, and the wrong cigarettes are shipped out. The box is returned to the warehouse to update the inventory information and re-join the calculation queue to ensure that the subsequent batches of goods are shipped in accordance with the formula and homogenization requirements; when the box number information detected by RFID is consistent with the nameplate and the shipping batch information is also consistent, but inconsistent with the box turning feeding channel specified by the system, it is a box turning error. The cigarette box is not transported to the designated box turning feeder. The cigarette box is taken off the line through the box turning feeding area offline platform, and is moved to the box turning feeding area online platform by a forklift, and then transported to the correct box turning feeder channel and the box turning feeding is resumed to ensure that the box turning feeding of this batch meets the formula and homogenization requirements.

[0027] The beneficial effects of the present invention are:

[0028] The present invention uses the original cigarette box to directly carry out single-level storage and formula outbound storage, reduces the process of taking tobacco leaves out of the frame for leaf laying and boxing, and reduces crushing; utilizes vertical conveyors for multi-level height transportation, and the formula three-dimensional warehouse adopts the method of outbound storage on the second floor and storage on the first floor, which is convenient for formula three-dimensional warehouse management and does not cause confusion; according to the homogenized formula outbound storage requirements, the queue of each batch of outbound cigarette boxes is shipped out in a fixed order. When the outbound verification finds that there is an error in the cigarette box, the wrong cigarette box returns to the warehouse through a bypass, and the system automatically finds the correct cigarette box, uses the vertical conveyor to cross the next box of tobacco leaves from the first floor cross-warehouse channel, and queues up to the location of the original wrong cigarette box, keeps the outbound queue unchanged, and ensures that each production batch meets the formula and homogenization requirements; before turning the box and unloading the material, a second verification is required to ensure that the production batch meets the formula and homogenization requirements, thereby improving the degree of automation of raw cigarette proportioning packing and formula warehouse logistics transportation; by setting multiple conveying channels with different functions, the cigarette box transportation is more orderly, and the cigarette box transportation efficiency is improved.

DETAILED DESCRIPTION

[0036] In order to make the objectives, technical solutions and beneficial effects of the present invention more clear, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0037] like Figure 2 、 3 As shown, a raw tobacco proportioning and packing system includes an empty box buffer line 5, a packing station 6, a raw tobacco frame loading station 6.1, a raw tobacco frame unloading station 6.2, a belt conveyor 7, a dual-channel slitting machine 8, a leaf laying line 9, a tobacco box conveying line 10, and an abnormality handling station 10.1. The leaf laying line 9 is connected to two dual-channel slitting machines 8 respectively. The discharge port of the dual-channel slitting machine 8 is connected to the two packing stations 6 respectively through four belt conveyors 7. The dual-channel slitting machine 8 cuts tobacco leaves according to different production requirements into leaf base and non-leaf base. The cut tobacco leaves are mixed by the multi-mode belt conveyor group of the dual-channel slitting machine 8. Or diversion, it can also be transported without cutting, the empty box buffer line 5 is set at the front end below the packing station 6, and the empty box buffer line 5 is provided with 61 buffer stations. After the cigarette frame is packed, the full box enters the information writing station, and the relevant information such as tobacco grade, batch, weight, specification, time, chemical composition value, etc. is written into the RFID. The cigarette box conveyor line 10 is set at the rear end below the packing station 6, and the cigarette box conveyor line 10 is connected to the formula three-dimensional library 12. The middle section of the cigarette box conveyor line 10 is provided with an abnormality processing station 10.1 for handling RFID abnormality processing after packing, cigarette frame abnormality processing and packed tobacco abnormality processing;

[0038] A raw tobacco proportioning and packing system can be used for offline cutting and framing of raw tobacco. The leaf laying and cutting line and a corresponding set of packing systems simultaneously have the functions of online packing of cigarette boxes from the formula library and offline packing of raw tobacco. Under the packing station 6, there is a raw tobacco frame loading station 6.1, a logistics route, and a raw tobacco frame unloading station 6.2. When using cigarette frame packing, empty cigarette frames are loaded onto the line from the raw tobacco frame loading station 6.1 by a forklift. After packing, the cigarette frames do not enter the production line or the formula three-dimensional warehouse, but are transported to a designated storage location by a forklift via the raw tobacco frame unloading station 6.2. While this set of packing station 6 is performing offline packing of raw tobacco, the other three sets of packing systems can continue to perform their cutting, packing, and storage functions normally without interfering with each other.

[0039] The formula warehouse logistics system includes a box turning feeding area 1, a manual processing area 2, an initialization loading and unloading platform 3, an empty box cleaning platform 3.1, an aisle stacker 11, a formula three-dimensional warehouse 12, a vertical conveyor 13, a buffer station 14, a box turning feeding area loading and unloading platform 14.1, a vacuum rehumidification machine 15, a return route 16, and a box turning feeding area loading and unloading platform 16.1. Four vertical conveyors 13 are installed at the front end of the formula three-dimensional warehouse 12. The two vertical conveyors 13 near the packing station 6 are used to transport empty cigarette boxes, returned cigarette boxes, and cigarette boxes that need to be queued out due to abnormal box turning. The two at the rear are used for cigarette box outbound. During normal inbound and outbound operation, the vertical conveyors work in pairs. If one of them fails, the other will be responsible for all outbound tasks. If a cigarette box stays in the faulty conveyor, it will be handled according to the outbound abnormality process, and new cigarette boxes will be recalculated and dispatched to replace it. The cigarette box staying in the faulty conveyor will be returned to the warehouse after the fault is repaired and re-added to the homogenization calculation. The cigarette box conveyor line 10 is connected to the vertical conveyor 13. The first floor of the formula three-dimensional warehouse 12 is used for full box storage and empty box storage, and the second floor is used for full box storage. A plurality of aisle stackers 11 are set in the formula three-dimensional warehouse 12 for stacking and taking out full cigarette boxes. A scanning detection device is set at the lower end outlet of the vertical conveyor 13 at the exit of the formula three-dimensional warehouse 12. The scanning detection device includes an RFID scanner and a camera, which can read and write RFID chips, scan and identify the two-dimensional code of the cigarette box, and verify the information of the cigarette box. The camera is used for real-time monitoring and box number shooting to compare and verify the scanned information. When leaving the warehouse, the next cigarette box will enter the vertical conveyor only after the verification is normal, so as to avoid cigarette boxes occupying the channel when the queue needs to be cut in due to abnormality in leaving the warehouse; four cigarette box conveyor lines are set at the front end of the formula three-dimensional warehouse 12, such as Figure 2As shown, two conveyor lines HK are connected to the vacuum conditioning machine 15, and the other two conveyor lines MG and MJF are connected to the box turning feeder and the initialization loading and unloading platform 3 respectively, which are used for the storage of empty frames, the return of incorrect cigarette boxes, and the transportation of cigarette boxes that jump the queue. Five buffer stations 14 are respectively set up on the front and rear entry and exit lines of the vacuum conditioning machine 15. The buffer station 14 at the rear end of the vacuum conditioning machine 15 is connected to the box turning feeding area 1. Three buffer stations 14 are set up in front of each box turning station in front of the box turning feeding area 1. Scanning detection devices are also set up on the buffer station 14 in the box turning feeding area 1 to check the cigarette box information again. If it is wrong, the exception processing is carried out. If it is correct, the box turning feeding continues. The box turning feeding area 1 is provided with the loading and unloading platform 14.1 and the box turning feeding area offline platform 16.1 at the left and right ends respectively for the loading and unloading of cigarette boxes. A return route 16 is set on the right side of the box turning and feeding area 1, and the return route 16 connects the empty box cache line 5 and the formula three-dimensional warehouse 12 respectively; an initialization loading and unloading platform 3 and an empty box cleaning platform 3.1 are set on the return route 16, and the initialization loading and unloading platform 3 is used for loading and unloading empty cigarette boxes and transporting queue-jumping cigarette boxes; a weighing detection device is set at the connection between the empty box cleaning platform 3.1 and the return route 16, and the weighing detection device includes a weighing sensor and a camera, which is used to detect whether there are residual tobacco leaves in the empty box. A manual processing area 2 for handling abnormal cigarette boxes is set next to the empty box cleaning platform 3.1.

[0040] A raw tobacco proportioning, boxing, and formula warehouse logistics system can handle single-grade storage and formula-based outbound storage of raw tobacco frames. After being palletized, the raw tobacco frames can be transported on a cigarette box conveyor line 10 and stored in a formula-based three-dimensional warehouse 12. When raw tobacco frames are put into storage, they are taken online by a forklift from the raw tobacco frame bar loading station 6.1, transported via the cigarette box conveyor line 10 to the cigarette box loading and unloading station, and then enter the formula-based three-dimensional warehouse 12. When tobacco frames are outbound, according to the outbound storage strategy generated by the proportioning, boxing, and homogenization formula management system, the aisle stacker 11 retrieves the tobacco frames from the designated cargo location and outbound storage in the planned sequence through the second-floor outbound platform. They are then transported via a vertical conveyor to the first floor of the formula-based three-dimensional warehouse 12, and then transported via the outbound transport line to a vacuum rehumidifier 15 or directly to the box turning feeding area 1 for feeding. This can reduce the process of removing tobacco leaves from the bars, laying them out, and boxing them, thereby reducing tobacco leaf breakage.

[0041] The aisle stacker 11 is configured with two modes: ordered and disordered delivery. When the stacker 11 is operating normally, ordered delivery is used, and each box of tobacco leaves is delivered strictly in the delivery order. The boxes of tobacco leaves from the next stacker can only be delivered after the boxes of tobacco leaves from the previous stacker have been delivered. When the stacker fails, it can be switched to disordered delivery. The system automatically sorts the boxes of tobacco leaves from the failed aisle to the last box of the batch to be delivered. However, the matching relationship between the boxes and the corresponding box feeders remains unchanged. Under the premise of ensuring that the delivery formula meets the requirements, the system can avoid the obstruction of tobacco boxes affecting delivery, maximize delivery efficiency, and ensure smooth production.

[0042] The central control room 4 is arranged on the left side of the empty box buffer line 5, and performs real-time control and monitoring of the raw cigarette proportioning and boxing and the formula library logistics transportation.

[0043] Figure 2 Among them, ABC line is the offline cutting and framing conveyor line for raw cigarettes, A is the empty cigarette frame online platform, B is the packing position, and C is the cigarette box offline platform; point D is the unqualified and abnormal cigarette box offline platform; cigarette box conveyor line 10 routes are CDF and CDG, F and G are cigarette box storage and pickup platforms; GE and MOE are empty box conveyor lines, point O is the empty box cleaning platform, HIK line is the outbound vacuum rehumidification transportation route, HIM is the cigarette box transportation route that does not require vacuum rehumidification; KM is the vacuum rehumidification cigarette line transportation route; FJL is the queue-jumping cigarette box transportation route, and JL is the forklift transportation route.

[0044] like Figure 1 、 3 As shown in FIG4 , a method for packing raw cigarettes into boxes and transporting the raw cigarettes from a formula library comprises the following steps:

[0045] S1. When the system goes online for the first time and production begins, the control system is initialized. An RFID maintenance device for cigarette cases is installed at the initial loading and unloading stations. RFID chips and case nameplates are manually installed, and empty cases are transported to the initial loading and unloading stations using a forklift. After an appearance inspection and weighing, the empty cases are loaded onto the RFID reader, which then writes basic information such as the weight and case number onto the RFID. The empty cases are then transported to the formula storage system via the empty case inbound channel JG.

[0046] S2. Process the tobacco leaves before packing, and transfer the empty boxes to the empty box cache line GE according to the system planning sequence to wait for packing. The empty box scheduling gives priority to the empty boxes returned by the return route NE, which can reduce the in-and-out flow of empty boxes. When the system flow cannot be met during the peak production period, empty tobacco boxes will be transferred from the formula three-dimensional warehouse.

[0047] S3. Tobacco packing. Before tobacco is packed, empty boxes are weighed and image inspected again before entering the packing station. If an abnormality is detected, the empty box will not be packed. After being marked, it will be transported to the manual station for processing, and empty boxes will be re-mobilized for replenishment. After packing is completed, the full box enters the information writing station, and the tobacco grade, batch, weight, specification, time, and chemical composition value information are written into the RFID before being put into storage. If a batch of tobacco leaves is packed, if the material loaded in the last tail box does not meet the packing accuracy requirements, the tail box will not be included in the homogenization formula and will be stored until the end of the batch for unified processing. If the RFID information cannot be written, the tobacco box will be transported to the abnormal processing station for processing. If the RFID is damaged, it will be manually replaced and the information will be rewritten before being put into storage. If it is due to other reasons, manual processing will be selected according to the specific situation or returned to the warehouse for unified outbound processing. The cigarette boxes are transported to the first-floor storage platform of the formula warehouse through the cigarette box conveyor line CF. Before storage, it is determined whether to cross the warehouse. If not, they are directly stored in the warehouse. If they need to cross the warehouse, they are transported to the vacuum rehumidification machine or the box turning feeding area through the vertical conveyor. The tobacco boxes that do not need to be transported to the first-floor pickup platform G of the formula warehouse are transported to the designated storage location according to the storage location information allocated by the upper management system.

[0048] S4. The system generates an outbound strategy based on the proportion packing and homogenization formula management system. The aisle stacker will call out the cigarette boxes on the designated cargo position and outbound them through the second-floor outbound platform in the planned order. They will be transported to the feeding area via the vertical conveyor. RFID information detection will be carried out in the feeding area before outbound. If the detection is passed, the cigarette boxes will be transported to the vacuum rehumidification machine through the outbound transport line or directly enter the cache station in the box turning and feeding area. If the RFID information cannot be read, but the box number information on the nameplate is consistent with the system prompt, the abnormal cigarette box will be marked and the transportation will be resumed. After the box turning and feeding is completed, it will be transported to the manual station to replace the RFID and then put into storage, or it will be put into storage first and then uniformly outbound for replacement; if the box number information on the RFID is inconsistent with the system prompt, but the box number information on the nameplate is consistent with the system prompt If the RFID box number is consistent with the nameplate, but inconsistent with the system prompts that the batch of cigarette boxes have been shipped out, it is an outbound error. After recalculation, the system will immediately call out the required cigarette boxes from the warehouse and insert the correct cigarette box into the original position of the abnormal cigarette box from the first-floor queue-jumping channel GI. Then, the vertical conveyor will resume the transportation of the next cigarette box to ensure that the outbound shipment of this batch meets the formula and homogenization requirements. The cigarette box with the wrong outbound shipment will be returned to the warehouse to update the inventory information and re-join the calculation queue to ensure that the outbound shipment of subsequent batches meets the formula and homogenization requirements. Only after the verification is normal will the next cigarette box enter the vertical conveyor to avoid cigarette boxes occupying the channel when the outbound shipment is abnormal and queue-jumping is required. During outbound delivery, if an anomaly on the second floor prevents delivery, delivery can be made through the first-floor cross-dock passage. During normal delivery, the two vertical conveyors work in conjunction. If one fails, the other takes over all delivery tasks. If a cigarette case remains on the faulty conveyor, it will be handled according to the outbound delivery abnormality process. Depending on production requirements, outbound delivery operations have two routes: one that undergoes vacuum rehumidification treatment and the other that does not. The vacuum rehumidification route is HIKM, and the non-vacuum rehumidification route is HIM.

[0049] S5. Vacuum conditioning: Tobacco cartons leaving the formula storage are sent to a buffer station in front of the vacuum conditioning machine, where they await entry into the machine. After vacuum conditioning, tobacco cartons are sent via conveyor line KM to the corresponding buffer station in the box turning and feeding area. After a secondary verification of RFID information, they are transferred to the feeder via the box turning feeder for production use.

[0050] S6. Cigarette cases that do not require vacuum conditioning are directly delivered by the HIM conveyor line to the buffer station in front of the corresponding case turning feeding area. After a second verification of the RFID information, they are turned into the feeder through the case turning feeder for production use.

[0051] S7. When the cigarette box is at the buffer station in front of the box turning and feeding area, the RFID information is secondary detected. After the detection is correct, it is turned into the feeder through the box turning feeder for production use; when an abnormal cigarette box is detected during the information verification before box turning and feeding, the system stops box turning and feeding, and automatically scans and identifies the cigarette box QR code through the camera. The frame cigarette image can also be transmitted to the management terminal monitoring interface for manual verification and corresponding situation processing; if the RFID information cannot be read, but the box number information on the nameplate is consistent with the system prompt, the abnormal cigarette box will be marked and the box turning and feeding will be resumed. After the box turning and feeding is completed, it will be transported to the manual station for RFID replacement and then put into storage, or it will be put into storage first and then uniformly shipped out for replacement; if the box number information of the RFID is inconsistent with the system prompt, but the box number information on the nameplate is consistent with the system prompt, the abnormal cigarette box will be marked and the transportation will be resumed. After the box turning and feeding is completed, it will be transported to the manual station for RFID information update and then put into storage, or it will be put into storage first and then uniformly shipped out for update; if the box number information of the RFID is consistent with the nameplate prompt, the abnormal cigarette box will be marked and the transportation will be resumed. If the number of cigarette boxes is consistent, but inconsistent with the system prompt, it is an outbound error. After recalculation, the system will immediately call out the required cigarette boxes from the warehouse and transport the correct cigarette boxes from the first-floor cross-warehouse channel FJ to the initialization up and down line platform J. The correct cigarette boxes are transported to the up-and-down line platform L in the box turning feeding area by forklift along route JL, and then inserted into the position of the original wrong cigarette box and resume box turning feeding to ensure that the outbound of this batch meets the formula and homogenization requirements. The wrong cigarette boxes are returned to the warehouse for processing to update the inventory information and re-enter the calculation queue to ensure the subsequent batches The outbound delivery meets the formula and homogenization requirements; when the box number information detected by RFID is consistent with the nameplate and the outbound batch information is also consistent, but inconsistent with the box turning feeding channel specified by the system, it is a box turning error, that is, the cigarette box is not conveyed to the designated box turning feeder. The cigarette box is taken off the line through the box turning feeding area offline station N, and is transported to the box turning feeding area online station L by a forklift along route NL. It is then conveyed to the correct box turning feeder channel and the box turning feeding is resumed to ensure that the box turning feeding of this batch meets the formula and homogenization requirements;

[0052] S8. After the box is turned over and fed, the empty box is processed and returned through the empty box return route NOE or NOF. The return route transportation process needs to undergo empty box inspection and cleaning. The cleanliness is automatically detected through image recognition. The empty boxes that pass the inspection are first sent to the cache station of the empty box cache line in front of the packing station for packing. When the cache station queue is full, it is transported to the first floor of the formula three-dimensional warehouse for storage; the empty boxes that fail the inspection are transported to the automatic turning equipment, and after turning, they are manually cleaned at the platform (O platform). After cleaning, the empty boxes are returned for re-inspection. After passing the inspection, they are transported to the cache station of the empty box cache line in front of the packing station or put into storage.

[0053] S9. Empty boxes on the empty box buffer line are returned to the warehouse in a centralized manner. When production is completed, the empty boxes on the empty box buffer line and the buffer stations in the packing area can be transported to the formula three-dimensional warehouse for storage through the cigarette box conveyor line.

[0054] The described method for offline slitting and framing raw cigarettes involves a leaf-laying and cutting line and a corresponding set of cartoning systems that simultaneously perform both online case packing from a recipe library and offline case packing of raw cigarettes. These systems are equipped with platforms A and C for entering and exiting raw cigarette frames, along with logistics routes. When using case packing, empty cigarette frames are brought online by a forklift from platform A. Completed frames at point B do not enter the production line or the recipe library, but are transported by a forklift to a designated storage location via platform C. While this cartoning station is performing offline case packing of raw cigarettes, the other three cartoning systems can continue their normal slitting, case packing, and warehousing functions without interfering with each other.

[0055] The method for single-grade warehousing of raw cigarette frames and outgoing warehousing of formula is as follows: the logistics line, stacker and shelf have the functions of conveying and storing the formula warehouse cigarette boxes and raw cigarette frames at the same time, and are provided with raw cigarette frame entry and exit platforms A and J and logistics routes. When cigarette frames are put into warehousing, the real cigarette frames and cigarette frame pallets are taken online by a forklift from the online platform A, and transported to the cigarette box entry and pickup platforms F and G through the cigarette box conveyor lines CF and CG, and enter the formula three-dimensional warehouse. When the cigarette frames are out of the warehouse, according to the outgoing warehousing strategy generated by the ratio packing and homogenization formula management system, the aisle stacker will call out the cigarette frames on the designated cargo position, and out of the warehouse through the second-floor outgoing platform H in the planned order, and transported to the first floor of the formula three-dimensional warehouse via the vertical conveyor, and transported to the vacuum rehumidification machine through the outgoing transport line GIKM or directly into the box turning feeding area through GIM for feeding. The process of taking tobacco leaves out of the frame for laying leaves and packing is reduced, and crushing is reduced.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.

A method for packing and transporting raw cigarettes in a proportioned manner and a formula library, applied to the raw cigarette packing and formula library logistics system according to claim 1, characterized in that: The method for packing raw cigarettes into boxes and transporting the formula library logistics comprises the following steps: S1. When the system is first put into production, the control system is initialized, the basic RFID information and box number of the empty box are written, and the box is transported to the formula storage system for storage; S2. Process the tobacco leaves before packing and transfer the empty boxes to the empty box cache line according to the system planning order to wait for packing; S3. The tobacco leaves are packed into boxes, their information is written, and the leaves are transported via the box conveyor line to the first-floor loading station of the formula warehouse. A check is performed to determine whether the leaves will be loaded into the warehouse from another warehouse. If not, they are directly loaded into the warehouse for storage. If they are loaded into another warehouse from another warehouse, they are transported to a vacuum rehumidifier or a box feeding area. S4. Based on the delivery strategy generated by the proportion packing and homogenization formula management system, the aisle stacker crane retrieves the cigarette case from the designated location and transports it to the front conveyor channel of the formula three-dimensional warehouse via the second-level delivery platform and the vertical conveyor in the order required by the delivery strategy. Before delivery, the RFID information is detected at the conveyor channel of the vertical conveyor exit. If the detection is passed, the case is transported to the vacuum rehumidification machine or directly to the buffer station in the box turning feeding area. If the information is incorrect, the delivery is stopped and the correct cigarette case is transferred from the vertical conveyor at the empty box inlet of the formula three-dimensional warehouse to jump the queue. The incorrect cigarette case is returned to the inlet channel. The information errors include the following: S4.1, if the RFID information cannot be read, but the box number information on the nameplate is consistent with the system prompt, mark the abnormal cigarette box and resume transportation. After the box turning and feeding are completed, it will be transported to the manual station for RFID replacement and then put into storage, or put into storage first and then shipped out for replacement; S4.2, if the box number information on the RFID is inconsistent with the system prompt, but the box number information on the nameplate is consistent with the system prompt, the abnormal cigarette box will be marked and the conveying will be resumed. After the box turning and feeding are completed, it will be conveyed to the manual station for RFID information update and then put into storage; S4.3: When the box number information detected by RFID is consistent with the nameplate, but inconsistent with the information of the cigarette boxes of the batch to be shipped prompted by the system, it is a shipping error. After recalculation, the system immediately calls out the required cigarette boxes from the warehouse through the vertical conveyor at the empty box entrance on the first floor of the formula three-dimensional warehouse. After inserting it to the original position of the abnormal cigarette box through the conveying channel, the vertical conveyor resumes the conveyance of the next cigarette box to ensure that the shipment of this batch meets the formula and homogenization requirements. The cigarette boxes with incorrect shipment are returned to the warehouse to update the inventory information and re-added to the calculation queue to ensure that the shipment of subsequent batches meets the formula and homogenization requirements. S5. Vacuum conditioning: The tobacco boxes shipped from the formula storage are sent to the buffer station in front of the vacuum conditioning machine, waiting to enter the conditioning machine for processing. The vacuum conditioning-completed tobacco boxes are sent to the corresponding buffer station in the feeding area via the conveyor system. S6. Cigarette cases that do not require vacuum conditioning are directly delivered by the conveyor system to the corresponding buffer station in the box turning and feeding area; S7. When cigarette cases are at the buffer station in the case-turning feeding area, the RFID information is secondary checked. If the check is correct, the case-turning feeder will turn the cigarette case into the feeder for production use. If an abnormal cigarette case is secondary detected, the system stops the case-turning feeding, analyzes the error, and takes appropriate measures. Among them, the secondary detection of abnormal cigarette boxes includes, when it is detected that the RFID information cannot be read and the box number information of the RFID is inconsistent with the system prompt, but the box number information on the nameplate is consistent with the system prompt, the processing is the same as S4.1 and S4.

2. When an outbound error is detected, the system will recalculate and immediately call out the required cigarette boxes from the warehouse and go offline from the initialization up and down line platform. The correct cigarette box is transported to the up-line platform of the box turning feeding area by a forklift, and then inserted into the position of the original wrong cigarette box and the box turning feeding is resumed to ensure that the outbound of this batch meets the formula and homogenization requirements, and the wrong cigarette box is shipped out. Do the return processing to update the inventory information, re-add it to the calculation queue, and ensure that the subsequent batches of goods are shipped in accordance with the formula and homogenization requirements; when the box number information detected by RFID is consistent with the nameplate and the outbound batch information is also consistent, but it is inconsistent with the box turning feeding channel specified by the system, it is a box turning error. The cigarette box has not been delivered to the designated box turning feeder. The cigarette box is taken off the line through the box turning feeding area offline station, and is moved to the box turning feeding area online station by a forklift. It is then transported to the correct box turning feeder channel and the box turning feeding is resumed to ensure that the box turning feeding of this batch meets the formula and homogenization requirements; S8. After the empty boxes are turned over and fed, they are processed and returned via the return route. During the return transport, they undergo inspection. Empty boxes that pass the inspection and are clean are first sent to the buffer station in front of the packing station for packing. Empty boxes that fail the inspection are sent to the manual cleaning station and, after cleaning, are returned for re-inspection. S9. Empty boxes on the empty box buffer line are returned to the warehouse in a centralized manner. When production is completed, the empty boxes on the empty box buffer line and the buffer stations in the packing area can be collectively transported to the formula three-dimensional warehouse for storage through the cigarette box conveyor line.

3. The method for packing raw cigarettes in proportions and transporting them in a formula library according to claim 2, characterized in that: The S2 and S8 empty boxes are preferentially mobilized from the return route to reduce the in-and-out flow of empty boxes. When the empty box buffer station is full, they are stored in the formula three-dimensional warehouse. When the system flow cannot be met during the peak production period, empty cigarette boxes are transferred from the formula three-dimensional warehouse.

4. The method for packing raw cigarettes and transporting them in a formula library according to claim 2, characterized in that: Before the S3 tobacco leaves are packed, the empty boxes are weighed and image-checked again before entering the packing station. If an abnormality is detected, the empty boxes will not be packed. After being marked, they will be transported to the abnormality processing station for processing, and empty boxes will be mobilized for replenishment. After the packing is completed, the full boxes enter the information writing station, and the tobacco grade, batch, weight, specification, time, and chemical composition value information are written into the RFID and then put into storage.
