Description

Technical Field

[0001] This invention belongs to the field of glass storage and packaging, specifically a method and system for intelligent glass storage and packaging. Background Technology

[0002] In glass manufacturing, due to the wide variety of glass sizes and specifications and the large number of small-batch orders, production is often coordinated according to the size specifications of multiple orders, resulting in mixed production lines for multiple specifications and orders. The produced glass is a mix of glass from different orders and of different specifications.

[0003] A glass sheet sorting warehouse is an automated storage and sorting device in a glass deep-processing production line. It records the information of incoming glass and performs inbound and outbound operations as needed. However, due to space limitations, most companies cannot set up large-area finished glass sheet sorting warehouses and cannot rely entirely on them for the classification, storage, sorting, and packaging of glass. In actual production, glass racks are often used to place finished glass according to processing sequence and specifications. During shipment, the glass on different racks needs to be further selected and packed according to the order. The glass sheet sorting and packing work during shipment is heavy and affects product delivery efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method and system for intelligent glass warehousing and packing, which can use a small glass sorting warehouse and glass racks to automatically sort products for outbound packing according to orders.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a glass intelligent warehousing and packing method, which sets up a rack storage area and a glass sorting and packing area. The rack storage area is used to place glass racks for loading finished glass for warehousing. The glass sorting and packing area is provided with a first glass sorting warehouse and a second glass sorting warehouse. The first glass sorting warehouse is used to receive glass to be packed, and the second glass sorting warehouse is used for buffering redundant glass and returning it to the glass rack for return. The glass on the glass rack for warehousing can be transferred to the first glass sorting warehouse or the second glass sorting warehouse through the warehousing transfer equipment. The first glass sorting warehouse is connected to the glass packing table through the outbound transfer equipment to output glass for packing. The packing method includes the following operations: (1) Obtain the packing task sheet that has completed the required glass production from the manufacturing system, select the packing task sheet that is ready to be packed from the packing task sheet to construct the packing task list, wherein each packing task sheet in the packing task list corresponds to a glass list for a packing task. (2) Based on the glass list of the packing task in the packing task list, conduct an inventory check, remove the glass stored in the first glass sorting warehouse and the second glass sorting warehouse, and generate an inbound demand list. (3) According to the inbound demand list, select the glass rack for inbound storage that contains the glass required for inbound storage in the vehicle frame storage area. Scan and identify the glass on the selected glass rack for inbound storage piece by piece through the inbound transfer equipment. According to the identification results, transfer the glass that exists in the inbound demand list to the first glass sorting warehouse and transfer other redundant glass to the second glass sorting warehouse. (4) After all the glass in the glass list of the packing task has been stored in the first glass storage library and / or the second glass storage library, the glass list of the packing task is converted into the outbound request glass list, and the packing task is removed from the packing task list. (5) According to the outbound request glass list, the glass stored in the first glass handling warehouse and / or the second glass handling warehouse is transferred to the glass packing table for packing in the order of packing through the outbound transfer equipment; (6) Repeat steps (1) to (5) until the packing of the selected packing task is completed.

[0006] When the remaining space in the first glass storage room is below a set threshold, but an inbound operation must be performed, the glass in the inbound demand list can also be temporarily stored in the second glass storage room; when the remaining space in the second glass storage room is below a set threshold, redundant glass can also be stored in the first glass storage room or directly returned to the return glass rack.

[0007] The packing task sheet corresponds to a glass list in an order, or a partial glass list in an order that fulfills a packing task.

[0008] The area within the vehicle frame storage area where each glass rack for inbound storage is placed is coded according to its location. Information about the glass stored on the glass racks is recorded in the manufacturing system. When performing a packing task, the system calculates the action cost based on the inbound demand list, the location of the glass racks, and the information about the glass stored on them, and generates instructions to schedule the glass racks. Based on these instructions, the glass racks that meet the requirements are moved to the inbound transfer equipment for glass storage.

[0009] When placing glass into the first or second glass sorting warehouse, if the glass cannot be placed in the packing order within the same warehouse location, the glass for the same packing task will not be placed in the same warehouse location.

[0010] After the glass list for the packing task is converted into the outbound request glass list, the glass in the glass list is locked in the first glass storage warehouse and the second glass storage warehouse. The inbound and outbound planning of other tasks avoids the locked glass.

[0011] When the remaining space in the second glass shelf is lower than the set threshold, the packing and shipping sequence is predicted, and a return task is initiated. Glasses that are later in the packing and shipping sequence are transferred to a return glass rack via a return transfer device.

[0012] When a return task is initiated, glass that has already been produced but is not on the packing task list will be returned to the warehouse first. Based on the production progress data of the manufacturing execution system, the packing and delivery order will be predicted according to the glass production completion rate of each packing task. Packing tasks with low completion rates will have their glass packed and delivered later.

[0013] A smart glass warehousing and packing system includes a rack storage area, a glass sorting and packing area, and a packing control unit. The rack storage area contains glass racks for loading finished glass products. The glass sorting and packing area includes a first glass sorting warehouse, a second glass sorting warehouse, and inbound transfer equipment. The inbound transfer equipment is used to transfer glass from the glass racks to the first or second glass sorting warehouse, and to transfer glass between the first and second glass sorting warehouses. An outbound transfer device connected to a glass packing table is located on one side of the first glass sorting warehouse. A return transfer device is located on one side of the second glass sorting warehouse. The inbound, outbound, and return transfer devices are scheduled by the packing control unit for glass transfer.

[0014] The first and second glass slide storage units are arranged side-by-side with intervals between them. An inbound transfer device is located between them. The inbound transfer device includes a vertical loading machine and an inbound shuttle transfer vehicle. The running track of the inbound shuttle transfer vehicle is located between the first and second glass slide storage units, and one end of the running track is connected to the vertical loading machine. The vertical loading machine is used to receive glass transferred from the inbound glass rack and scan and identify it. The outbound transfer device includes a vertical unloading machine and an outbound shuttle transfer vehicle. The running track of the outbound shuttle transfer vehicle is located on one side of the second glass slide storage unit, and one end of the running track is connected to the vertical unloading machine.

[0015] The outbound transfer equipment includes an outbound shuttle transfer vehicle, and multiple glass packing platforms are provided on one side of the outbound shuttle transfer vehicle's running track.

[0016] The glass racks for warehousing are moved from the rack storage area to the warehousing transfer equipment via AGV trolleys or glass rack transfer vehicles. The vehicle frame storage area is equipped with storage transfer equipment and storage racks. The storage racks hold incoming glass racks. The storage transfer equipment includes guide rails and a storage shuttle car that moves along the guide rails. The incoming glass racks carrying finished glass can be transferred from the storage racks to the storage shuttle car, and then from the storage shuttle car to the storage transfer equipment.

[0017] It also includes a chassis waiting area, which contains glass racks for loading finished glass for storage, to replenish the glass racks in the chassis storage area.

[0018] The beneficial effects of this invention are: 1. This intelligent packing method can automatically sort out the required products and specifications according to orders, conduct inventory of glass in the warehouse, and determine whether the packing task requirements are met. If the packing task is not completed, products are picked from the glass racks for storage and put into the warehouse. Once the packing task is completed, the products are shipped out. It can also perform a secondary unloading of products that are not yet shipped, sorted by specification. It is particularly suitable for packing loose orders and multi-specification glass produced on mixed production lines.

[0019] 2. A first and second glass sorting warehouse are set up in the glass sorting and packing area, respectively, and work in conjunction with the glass racks for receiving goods in the vehicle frame storage area. This allows for flexible allocation of glass between warehouses based on demand. Glass awaiting packing is prioritized in the first glass sorting warehouse, while redundant glass already stored for retrieval of target glass is prioritized in the second glass sorting warehouse. Furthermore, when storage space is insufficient, glass not scheduled for immediate shipment in the second glass sorting warehouse can be removed first to prevent impacting the subsequent receiving and distribution of glass on the racks. This configuration utilizes two small glass sorting warehouses to handle the sorting and retrieval of glass during the packing process, saving space in the production workshop.

[0020] 3. The first glass sheet sorting warehouse and the second glass sheet sorting warehouse are set up side by side with intervals. The inbound and outbound packing operations of the first glass sheet sorting warehouse and the outbound operations of the second glass sheet sorting warehouse can be carried out simultaneously without interference, maximizing the efficiency of the first glass sheet sorting warehouse in sorting and packing the glass to be packed.

[0021] 4. Set up consolidation rules for glass warehousing. If glass for the same packing task cannot be placed in the packing order, it will not be placed in the same storage location to avoid interference during the packing process and improve packing efficiency and loading rate.

[0022] 5. By encoding the glass racks in the chassis storage area by location, and using the chassis scheduling and warehousing algorithm to calculate the action cost of the packing task warehousing operation based on the location of the glass rack and the information of the glass stored on the glass rack, the scheduling of glass racks can be saved to the greatest extent, and digital management and control of all produced glass and glass racks storing glass can be achieved.

[0023] 6. The first glass sheet handling warehouse connects to multiple glass packing stations through outbound transfer equipment. By combining the incoming glass and packing planning, multiple packing tasks can be generated simultaneously for outbound packing. Attached Figure Description

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. The specific contents listed in the following embodiments are not limited to the technical features necessary to solve the technical problem of the present invention. Furthermore, the listed embodiments are merely a part of the present invention, and not all embodiments.

[0033] Example 1

[0034] The intelligent glass warehousing and packing method of this invention requires, as follows: Figure 2 The factory is divided into a frame storage area 1 and a glass handling and packing area 2. Frame storage area 1 is used to store glass racks 3 for loading finished glass products. Each area within frame storage area 1 is coded according to its location, and information about the glass stored on each rack is recorded in the manufacturing execution system. During packing, the packing control unit can issue instructions to schedule the relevant glass racks based on this information.

[0035] The glass handling and packing area 2 includes a first glass handling warehouse 4 and a second glass handling warehouse 5. The first glass handling warehouse 4 receives glass to be packed, while the second glass handling warehouse 5 serves as a buffer for redundant glass and for returning glass to return racks. The glass transfer route is as follows: Figure 1 As shown, the glass on the glass racks in the vehicle frame storage area 1 can be transferred from the inbound port to the first or second glass rack via the inbound transfer equipment. The first glass rack connects to the glass packing table from the packing and shipping port via the outbound transfer equipment to output glass for packing. The second glass rack can return temporarily unwanted glass to the return glass rack via the return transfer equipment through the return port.

[0036] The packing method of the present invention includes the following operations: (1) Obtain packing task orders with completed glass production from the Manufacturing Execution System (MES). A single packing task order with completed glass production indicates that a portion of the glass in an order that can fulfill one packing task has been produced and can be packed, or that all the glass in an order has been produced and can be packed. The system automatically or the user selects packing task orders from the completed glass production packing task orders to construct a packing task list. Each entry in the packing task list corresponds to a glass list for one packing task, which may include information such as order number, batch number, glass specifications, and quantity.

[0037] The system determines whether the glass production required for the packing task has been completed by querying whether the glass quantity meets the requirements of the packing task order. The method is as follows: Subtract the locked glass (glass required for the currently executing packing task) from the glass unloaded from the racks (including glass racks for storage in the chassis inventory area and buffer glass racks on the production line) and the glass in the warehouse (first glass processing warehouse and second glass processing warehouse). If the result is greater than or equal to the glass quantity required by the packing task order, then the packing task order requirement has been met. If not, production waits.

[0038] (2) When generating the glass list for the packing task, the required glass may already be in the glass storage room in the packing area, or on the glass rack for receiving in the vehicle frame storage area, or it may still be temporarily stored on the production line after production is completed, waiting for its destination to be determined. The packing control unit of the system performs inventory checks and deductions based on the glass list of the packing task in the packing task list, automatically removes the glass stored in the first glass storage room and the second glass storage room, and generates a list of receiving requirements for glass that needs to be transferred from external sources for receiving.

[0039] (3) The packing control unit automatically selects the source of the glass to be dispatched based on the inbound demand list. If the glass is still waiting on the production line, it can directly issue an instruction to send it to the first glass sorting warehouse. If the glass is in the chassis storage area, the packing control unit selects the glass rack to be dispatched based on the inbound demand list and the chassis scheduling inbound algorithm. The algorithm calculates the action cost based on the site layout, the placement of the glass rack, and the information of the glass stored on the glass rack. For example, the glass in the inbound demand list is stored on different glass racks, and there are requirements for the order of glass packing; the outer glass rack blocks the deep glass rack, and the outer glass rack needs to be moved to retrieve the deep glass rack; in addition to the required glass, there are other glasses on the glass rack, and other glasses also need to be retrieved when the required glass is obtained. The packing control unit calculates in real time the number of glass racks to be moved, the moving distance, and the amount of redundant glass occupying the glass sorting warehouse space for different scheduling methods. Then, from different scheduling methods, the method with the lowest cost to achieve the current packing task (less glass rack movement, less storage space occupation) is selected, and a glass rack transfer guidance instruction is generated. This controls the automated equipment or guides the operator to determine which glass rack to pull or which obstructing glass rack to remove (e.g., moving glass rack 12-1 to the inlet, moving glass rack 10-2 to position 11-1). After each action is completed, the system immediately determines the next action based on the latest on-site status.

[0040] The packing control unit selects glass racks containing the required glass for warehousing from the vehicle frame storage area using the method described above, and then moves the selected glass racks to the warehousing transfer equipment for glass warehousing. During warehousing, the glass on the racks is scanned and identified piece by piece by the transfer equipment to determine the specifications, batch, and other information of each piece of glass. Based on the identification results, glass present in the warehousing demand list is transferred to the first glass sorting warehouse, and other redundant glass is transferred to the second glass sorting warehouse.

[0041] When glass is received into the warehouse, the packing control unit uses an inbound flow algorithm to automatically control the process based on the glass identification information obtained from scanning. This determines whether the glass enters the first or second glass sorting warehouse, and whether it needs to be grouped into multiple warehouses upon receipt. The inbound flow algorithm includes grouping rules and glass flow rules.

[0042] The rules for combining data into a single database include: (a) In-box stacking rule: Multiple pieces of glass from the same packing task should preferably not be placed in the same storage location, unless the multiple pieces of glass from the packing task are brought into the same storage location in the packing order. This method can reduce the impact of mutual interference during the packing and unpacking process.

[0043] (b) Stacking of glass of the same batch and specifications: Glass of the same batch and specifications may be stacked in the same storage location. When packing, glass in the same storage location belongs to the same customer and has the same specifications, and is not affected by the packing order.

[0044] (c) Arrange according to packing order: When glass from different packing orders must be mixed and arranged, compare the packing order and put the batches packed first into the storage location first, and the batches packed later into the storage location later.

[0045] Glass flow rules include: (a) Glass currently in the inbound demand list will be given priority to be guided into the first glass processing warehouse.

[0046] (b) Redundant glass that has been stored in the warehouse for the purpose of extracting the target glass is guided into the second glass processing warehouse.

[0047] (c) When the remaining space in the first glass storage warehouse is below a set threshold, but an inbound operation must be performed, the glass in the inbound demand list may be temporarily moved to the second glass storage warehouse, depending on the circumstances. When the remaining space in the second glass storage warehouse is below a set threshold, the glass may also be moved to the first glass storage warehouse, depending on the circumstances. When implementing this rule, it is necessary to predict the packing and shipping order based on the known data in the MES system. The first-packed glass will be moved to the first glass storage warehouse, and the later-packed glass will be moved to the second glass storage warehouse. The remaining space is preferably the number of remaining empty storage locations.

[0048] During system operation, the remaining capacity of the glass shelf can be determined in real time. When the remaining space in the second glass shelf falls below a set threshold, the system issues a warning to the user and requests the initiation of a return task to prevent the shelf from becoming full and halting the warehousing process. When initiating the return task, the packing and shipping sequence is predicted based on known data within the MES system. Glass with a later shipping sequence is transferred to a return glass rack via a return transfer device. Glass in packing orders that have completed the required glass production is considered glass ready for packing and is kept in the shelf as much as possible to minimize unnecessary handling. Glass not in packing orders that have completed the required glass production is returned first. Based on the production progress data from the Manufacturing Execution System, the packing and shipping sequence is predicted according to the glass production completion rate of each packing task. Packing tasks with lower completion rates have a later packing and shipping sequence. For example, if some glass is only 2 pieces short of 10 pieces for a packing task, it is predicted that these 10 pieces will be packed first. The selected unused glass will be removed from the warehouse and placed on the return glass rack in sequence according to the specified sorting rules.

[0049] (4) After all the glass in the glass list of the packing task has been stored in the first glass storage warehouse and the second glass storage warehouse, the user (or the system automatically) assigns the packing task to a specific packing and shipping port. The glass list of the packing task is converted into an outbound request glass list, and the packing task is removed from the packing task list. At the same time, the glass in the glass list is locked in the first glass storage warehouse and the second glass storage warehouse. When other packing tasks take inventory of the glass in the warehouse, these glasses will not be counted, so as to prevent the packing process from affecting the warehousing plan.

[0050] (5) Transfer the glass stored in the second glass handling warehouse in the outbound request glass list to the first glass handling warehouse, and according to the outbound request glass list, transfer the glass from the first glass handling warehouse to the glass packing table for packing through the outbound transfer equipment in the packing order.

[0051] (6) Repeat steps (1) to (5) until all packing tasks are completed.

[0052] When executing the packing procedure, you can select one packing task order to create a packing task list and execute one packing task at a time. Alternatively, you can select multiple packing task orders to create packing tasks simultaneously. Different packing tasks can be assigned to different packing and shipping ports; for example, three packing tasks can be assigned to different shipping ports. Figure 1 The packing and shipping ports 1-3 are shown. When multiple packing tasks are executed simultaneously, the operations are sorted according to the packing progress, and the selection of glass racks for warehousing and the warehousing operation are performed according to the rules mentioned above.

[0053] This packing system allows users to manually add or modify tasks. For example, users can select a packing task order and add it to the packing task list to force priority packing, or adjust the order of the packing tasks. When the contents of the packing task list change, the system will adjust the operation guidance of the glass racks and the glass warehousing plan in real time during the next action calculation. In special circumstances requiring the temporary release of some glass, users can create a custom export request list at any packing and shipping port in the system to release the required glass. Similarly, the return operation also supports users creating custom return lists to handle special situations.

[0054] like Figure 2 As shown, the intelligent glass warehousing and packing system of the present invention includes a frame storage area 1, a glass sorting and packing area 2, and a packing control unit. The frame storage area 1 contains glass racks 3 for loading finished glass products. Multiple glass racks 3 are placed in the frame storage area 1 according to the planned area numbering.

[0055] The glass sorting and packing area 2 includes a first glass sorting warehouse 4 and a second glass sorting warehouse 5. Both warehouses are vertical storage units for vertical glass storage. The first glass sorting warehouse 4 comprises one or more storage units, and the second glass sorting warehouse 5 comprises one or more storage units. Each storage unit includes multiple storage locations, and each location is used for vertical storage of one or more pieces of glass. The glass storage capacity is affected by the number of storage locations in the first and second glass sorting warehouses. Both the first and second glass sorting warehouses include a rack and a movable storage trolley. The movable storage trolley is located at the bottom of the rack and can move along a track to the bottom of the corresponding storage location to output or input glass.

[0056] The first glass storage area 4 and the second glass storage area 5 are arranged side by side at intervals, with an inbound transfer device between them. The inbound transfer device includes a vertical glass loading machine 9 and an inbound shuttle transfer vehicle 7. The vertical glass loading machine 9 is located at the inlet of the loading area 2, connecting to the rack storage area 1, and is used to receive glass transferred from the inbound glass racks and scan and identify it. The running track of the inbound shuttle transfer vehicle 7 is set between the first glass storage area 4 and the second glass storage area 5, with one end of the track connected to the vertical glass loading machine 9. The inbound transfer device can transfer glass from the inbound glass racks in the rack storage area 1 to either the first glass storage area 4 or the second glass storage area 5. The vertical glass loading machine 9 is equipped with a barcode scanner 10, which can scan the codes attached to the glass to identify information such as glass batch and specifications.

[0057] Upon arrival at the warehouse, glass racks for storage in rack storage area 1 can be transferred using AGV trolleys, or manually using glass rack transfer cart 14 according to operating instructions to dispatch glass racks from rack storage area 1 to glass sorting and packing area 2. The inbound transfer equipment is also used for glass transfer between the first glass sorting warehouse and the second glass sorting warehouse.

[0058] One side of the first glass storage warehouse 4 is equipped with outbound transfer equipment that connects to the glass packing platform 12. This outbound transfer equipment includes an outbound shuttle transfer vehicle 6, and multiple glass packing platforms 12 are located on one side of the shuttle transfer vehicle 6's running track. The glass packing platforms 12 are connected to the outbound shuttle transfer vehicle 6 via a conveyor platform 13, enabling the glass to be flipped from upright to flat. The flipped glass is then sent to the glass packing platform 12 for packing and shipping.

[0059] A return and transfer device is installed on one side of the second glass storage compartment 5. This device includes a vertical unloading machine 11 and a return shuttle 8. The running track of the return shuttle 8 is located on one side of the second glass storage compartment 5, and one end of the track connects to the vertical unloading machine 11. The inbound, outbound, and return glass transfer devices are scheduled by the packing control unit. Inbound, outbound, and return operations are performed by independent transfer equipment, resulting in high efficiency.

[0060] One inbound shuttle transfer vehicle 7, one outbound shuttle transfer vehicle 8, and one outbound shuttle transfer vehicle 6 are each provided for the transfer of glass. The number of inbound shuttle transfer vehicles 7, outbound shuttle transfer vehicles 8, and outbound shuttle transfer vehicles 6 can be more than two, mainly determined by the number of storage locations and the designed glass handling capacity of the first glass handling warehouse 4 and the second glass handling warehouse 5.

[0061] Alternatives, such as Figure 4 Two vertical loading machines and two vertical unloading machines can be set up respectively. Two first glass slide storage boxes 4 and two second glass slide storage boxes 5 can also be set up side by side, which can improve the slide handling capacity to a certain extent.

[0062] It should be noted that glass racks carrying excess glass that has been returned to the warehouse can be transferred to the temporary storage area or the vehicle frame storage area 1.

[0063] In the above embodiment, the first glass slide holder and the second glass slide holder are arranged alternately. Alternatively, the first glass slide holder and the second glass slide holder can also be arranged as follows: Figure 5 The parallel design shown can also achieve the intended function. Different layouts are related not only to the expected efficiency of sheet handling and packing, but also to the available space for equipment installation in the factory.

[0064] Furthermore, a waiting area for the chassis can be set up, such as... Figure 3 AGVs or glass rack transfer vehicles are used to move glass racks from the rack waiting area to the rack storage area, ensuring that the racks in the rack storage area are always loaded with glass.

[0065] Example 2

[0066] Unlike the embodiments described above, as Figure 6 The chassis storage area 1 is equipped with storage transfer equipment and storage racks 17. Glass racks 3 for inbound shipments are placed on the storage racks 17. The storage transfer equipment includes guide rails and a storage shuttle 16 that moves along the guide rails. Glass racks 3 carrying finished glass can be transferred from the storage racks 17 to the storage shuttle 16, and then moved by the storage shuttle 16 to the entrance of the storage transfer equipment. The storage transfer equipment then dispatches the glass racks 3 from the chassis storage area 1 to the sheet handling and packing area 2.

[0067] Furthermore, such as Figure 7 A frame waiting area 15 is also provided. The frame waiting area 15 is also equipped with inventory transfer equipment and storage racks, and the inventory transfer equipment is used to dispatch glass frames from the frame waiting area to the frame storage area.

[0068] The glass racks in the chassis waiting area 15 can be dispatched from the chassis waiting area to the chassis storage area through the cooperation of multiple inventory transfer devices and multiple storage racks.

[0069] It should be noted that, alternatively, the first glass storage unit 4 and the second glass storage unit 5 can also be horizontal storage units for horizontal storage of glass. In this case, a liftable platform can be set at the exit and entrance of each storage unit for the input and output of glass at different storage heights.

[0070] The above description of specific embodiments is only for the purpose of helping to understand the technical concept and core idea of ​​the present invention. Although specific preferred embodiments have been used to describe and illustrate the technical solutions, they should not be construed as limiting the present invention itself. Those skilled in the art can make various changes in form and detail without departing from the technical concept of the present invention. These easily conceived changes or substitutions should all be covered within the protection scope of the present invention.
