Description

Technical Field

[0001] This invention relates to a roll packing production line, and more particularly to an RFID-based roll sorting and packing production line. Background Technology

[0002] When packaging yarn rolls, manufacturers need to classify and box them based on their quality and specifications to achieve standardized production. Currently, the classification and boxing method for yarn rolls involves setting up a corresponding number of packaging conveyor lines based on the packaging type. Each packaging conveyor line corresponds to one type of yarn roll, thus utilizing different packaging conveyor lines to individually box various types of yarn rolls, ensuring effective classification and boxing.

[0003] However, the difference between silk rolls and other rolled materials lies in the fact that silk rolls require a single thread to be wound into shape during the winding process. If a thread breakage occurs during winding, the silk roll is directly removed from the roll as a finished product. This results in inconsistent weight and outer diameter after processing. The longer the thread wrapped around the surface of the silk roll, the larger its outer diameter and weight; conversely, the shorter the thread, the smaller its outer diameter and weight. Furthermore, these outer diameter and weight can vary arbitrarily within a certain range and are not under the manufacturer's control. For this type of silk roll, the current packaging method has a drawback: as the market increasingly demands higher quality and specifications for silk rolls, there are now three to six different quality levels, and each quality is further classified based on weight or outer diameter to meet market packaging requirements. For example, it's difficult to control the total weight of each box of silk rolls within a certain range, or to maintain a relatively consistent outer diameter within the same box. This classification method results in more than a dozen different packaging types for the yarn rolls during the initial sorting process, with significant differences in the quantity of each type. For example, yarn rolls of the same packaging type might account for more than 50% of the total, while the remaining rolls are distributed among other packaging types. This makes it impossible for manufacturers to either set up a separate conveyor line for each packaging type or to use the same conveyor line to mix and pack yarn rolls of different packaging types, thus greatly increasing the difficulty of packaging the yarn rolls for manufacturers.

[0004] Secondly, during the processing of a batch of yarn rolls, manufacturers often encounter situations where several repackaged yarn rolls cannot be fully packed into cartons. This means that the remaining quantity of that repackaged type of yarn roll is insufficient to fill a single carton, or the number of cartons on a pallet does not meet the shipping requirements. This makes it difficult for manufacturers to handle these stranded yarn rolls. Furthermore, when the next batch of yarn rolls is produced and cartons or pallets can be replenished, it is difficult for manufacturers to complete the packing process for these remaining yarn rolls using a production line. Instead, manual replenishment and sealing of the cartons are required, further increasing the difficulty of packing the yarn rolls for the manufacturer.

[0005] Therefore, existing packing lines cannot pack and repack various types of spools. Summary of the Invention

[0006] The purpose of this invention is to provide an RFID-based roll material sorting and packing production line. It can pack and replenish roll materials of different packaging types, effectively improving the packing efficiency and quality of the roll materials.

[0007] The technical solution of the present invention is: an RFID-based roll material sorting and packing production line, including a conveyor line, on which several rolls are distributed, each roll being provided with a first identification code, and the outside of the conveyor line is provided with a weighing and diameter measuring station, an inspection station, a film suction and film covering station, a sorting station and a packing station in sequence along the conveying direction.

[0008] The coil is used to support and transport the coiled material;

[0009] The weighing and diameter measuring station is used to detect the outer diameter and / or weight of the roll material, and the detection result is entered into the control system as the roll material specification through the first identification code;

[0010] The inspection station is used to identify or inspect the quality of the rolled material and to enter the results into the control system via the first identification code.

[0011] The film suction and wrapping station is used to wrap packaging film on the outside of the roll material;

[0012] The sorting station includes a feeding conveyor belt located in the middle of the conveyor line. Multiple circulating discharge components are connected to one side of the feeding conveyor belt. The circulating discharge components include a forward circulating conveyor belt, one end of which is connected to the feeding conveyor belt, and the other end of which is connected to a first discharge conveyor belt. A reverse circulating conveyor belt is provided on one side of the forward circulating conveyor belt. Both ends of the reverse circulating conveyor belt are connected to the forward circulating conveyor belt via a turning conveyor belt. The forward circulating conveyor belt, the turning conveyor belt, and the reverse circulating conveyor belt form a circular circulation line.

[0013] The feeding conveyor belt is used to identify the quality of the roll material via the first identification code and to feed the roll material into the corresponding circulating discharge assembly according to the quality of the roll material.

[0014] The circulating discharge assembly is used to identify the quality and specifications of the roll material via the first identification code, and to control the roll material to enter the first discharge conveyor belt or move continuously along the circulating line according to the quality and specifications of the roll material.

[0015] The packing station includes a packing mechanism. A packaging conveyor belt is located outside the conveyor line on one side of the packing mechanism. At least one packing conveyor belt is located between the packaging conveyor belt and the sorting station. One end of the packing conveyor belt is connected to the packaging conveyor belt, and the other end of the packing conveyor belt is connected to a transfer conveyor belt located in the middle of the conveyor line. The outside of the transfer conveyor belt is connected to the first discharge conveyor belt. A sealing mechanism is located in the middle of the packaging conveyor belt. A transfer station is formed at the end of the packaging conveyor belt. A transfer mechanism is located on one side of the transfer station. A return conveyor belt and multiple buffer conveyor belts are respectively located outside the transfer mechanism. The end of the return conveyor belt is connected to the packaging conveyor belt. A manual box replenishment station is formed on one side of the return conveyor belt or the packaging conveyor belt.

[0016] The first discharge conveyor belt is used to feed the roll material into the transfer conveyor belt;

[0017] The transfer conveyor belt is used to identify the quality and specifications of the roll material via the first identification code, and the packing mechanism packs the roll material into boxes according to the identification result.

[0018] The packaging conveyor belt is used to seal the cartons after they have been packed and transport them to the transfer station.

[0019] The transfer station is used to identify the quality and specifications of the roll material by the first identification code, and the transfer mechanism transfers the carton to the pallet of the corresponding buffer conveyor belt according to the identification result, or transfers the unfilled carton on the top of the pallet to the return conveyor belt.

[0020] The return conveyor belt is used to transport cartons that are not fully loaded with material to the packaging conveyor belt;

[0021] The manual refill station is used to manually place rolls of material into cardboard boxes that are not fully filled.

[0022] In the aforementioned RFID-based roll material sorting and packing production line, a first guide component is provided at the connection between the forward circulating conveyor belt and the first discharge conveyor belt. Multiple second guide components that cooperate with the circulating discharge component are distributed at intervals on the feeding conveyor belt. Each first guide component has a first RFID reader / writer that cooperates with the first identification code on one side. Each second guide component has a second RFID reader / writer that cooperates with the first identification code on one side. Both the first RFID reader / writer and the second RFID reader / writer are used to read the quality and specifications of the roll material on the roll tube through the first identification code.

[0023] In the aforementioned RFID-based roll sorting and packing production line, at least one second discharge conveyor belt is connected to one side of the feeding conveyor belt. The circulating discharge component and the second discharge conveyor belt are arranged at intervals along the conveying direction of the feeding conveyor belt. A third guide component is provided on the feeding conveyor belt to cooperate with the second discharge conveyor belt. The end of the second discharge conveyor belt is connected to a transfer conveyor belt.

[0024] The aforementioned RFID-based roll sorting and packing production line also includes a carton conveyor belt located between the transfer conveyor belt and the packing conveyor belt. The front end of the carton conveyor belt along the conveying direction is equipped with an opening mechanism, and the packing conveyor belt is connected to the carton conveyor belt at the end away from the sealing conveyor belt.

[0025] In the aforementioned RFID-based roll sorting and packing production line, the packing conveyor belt forms a packing position near one end of the carton conveyor belt. A top rod and a baffle are respectively provided on both sides of the packing position. The lower ends of the top rod and the baffle are connected to telescopic components. The baffle is used to limit one end of the carton during packing, and the top rod is used to push the other end of the carton during packing, so that the carton remains tilted during the packing process.

[0026] In the aforementioned RFID-based roll material sorting and packing production line, the carton is equipped with a second identification code, the packing conveyor belt is equipped with a third RFID reader that works in conjunction with the second identification code, and the transfer station is equipped with a fourth RFID reader that works in conjunction with the second identification code. The third RFID reader is used to input the quality and specifications of the packed roll material into the control system via the second identification code, so that the content of each second identification code includes the quality and specifications of all roll materials in the carton. The fourth RFID reader is used to read the quality and specifications of the roll material in the carton via the second identification code, and to input the stacking information of the carton into the control system via the second identification code, so that the information of each carton on each pallet is interconnected.

[0027] In the aforementioned RFID-based roll material sorting and packing production line, when a batch of roll materials is packed, if the number of cartons on any pallet or the number of roll materials in any carton does not meet the requirements, the sorting station and packing station directly complete the packing process of the roll materials and put the carton and pallet together into the temporary storage area for temporary storage; when the next batch of roll materials is packed, the operator first puts the pallet in the temporary storage area together with the carton into the buffer conveyor belt, and the buffer conveyor belt reads the second identification code of any carton on the pallet and then replenishes the pallet through the packing station until the pallet is packed.

[0028] In the aforementioned RFID-based roll sorting and packing production line, the transfer conveyor belt is equipped with a fifth RFID reader that matches the first identification code, and the buffer conveyor belt is equipped with a sixth RFID reader that matches the second identification code.

[0029] In the aforementioned RFID-based roll sorting and packing production line, the roll specification refers to the roll outer diameter. The control system is manually set by the operator based on the roll outer diameter range to determine the packing type. When the roll continuously moves within the circulation line, the control system judges the quality and specifications of the roll within the current circulation line based on the packing type. If the number of rolls in the current circulation line that meet the same packing type reaches the packing quantity, the control system controls the circulating discharge component to send all the corresponding rolls into the first discharge conveyor belt. Otherwise, the roll continues to move within the circulation line.

[0030] In the aforementioned RFID-based roll sorting and packing production line, the roll specification is the roll weight. The control system is manually set to determine the total weight of the rolls in the carton. When the rolls move continuously in the circulation line, the control system judges and filters the quality and specifications of the rolls in the current circulation line based on the remaining packing weight of the carton during the packing process, thereby selecting the rolls that meet the remaining packing weight and sending them into the first discharge conveyor belt.

[0031] Compared with the prior art, the present invention has the following characteristics:

[0032] (1) By limiting the structure of the sorting station, the present invention enables the roll material to circulate along the circulation line within the circulation discharge assembly after entering the circulation discharge assembly. The circulation discharge assembly identifies the quality and specifications of each roll material during the movement of the roll material. If the specifications of the roll material meet the current packing requirements, the roll material is controlled to leave the circulation line and enter the first discharge conveyor belt, thereby realizing the discharge and packing process of the roll material. If the specifications of the roll material do not meet the current packing requirements, the roll material continues to move within the circulation line, thereby realizing the temporary storage of roll materials of various different packaging types. With the above combination, the present invention can realize the temporary storage and screening of multiple roll materials of different specifications, thereby effectively reducing the number of circulation discharge assemblies while meeting their packing requirements. It can also prevent other roll materials from interfering with the current packing specifications of the roll material, and avoid the long-term occupation of the packing station due to the inability to quickly complete the packing of a certain type of carton.

[0033] (2) By limiting the cooperation between the circulating discharge component and the second discharge conveyor belt, the manufacturer can also set up a corresponding number of discharge facilities based on the quality of the roll material, so that each discharge facility can pack a roll material of a certain quality, thereby improving the manufacturer's packing efficiency; on the other hand, the present invention can also select the type of discharge facility according to the specifications of the roll material, that is, when there are multiple specifications in the roll material of the same quality, the circulating discharge component is selected for screening and discharge; when there is only one specification in the roll material of the same quality, the second discharge conveyor belt is selected for direct discharge, which improves the functionality and discharge effect of the present invention.

[0034] (3) Through the cooperation of the return conveyor belt, transfer station, manual box replenishment station and box packing mechanism, when the roll material cannot be filled into the carton normally due to insufficient remaining material, the carton can be sealed and stored in the conventional way first; after the next batch of roll material is produced, the operator puts the carton and the pallet back on the buffer conveyor belt, and the transfer mechanism grabs the unfilled carton on the top of the pallet and places it separately on the return conveyor belt, so that the unfilled carton enters the manual box replenishment station and the sealing conveyor belt along the return conveyor belt; when the unfilled carton enters the manual box replenishment station, the operator can open the carton again, and the box packing mechanism puts the corresponding roll material on the production line into the manual box replenishment station, so as to complete the box packing work manually; after the box packing is completed, the carton is resealed by the sealing conveyor belt, and the transfer mechanism puts the carton back on the original pallet in the conventional way, so as to realize the repacking of the carton and reduce the workload of the operator in the repacking process;

[0035] (4) Through the cooperation of the top rod and the baffle, the carton can be tilted during the packing process, so that after the packing mechanism puts the roll into the carton, the roll can be stacked along the inner wall of one side of the carton as a support surface; and when the bottom cardboard of the carton is tilted, the roll can also be tilted and stacked after being placed, which effectively prevents the roll from being overturned by force and improves the packing stability of the roll.

[0036] (5) By setting identification codes on cartons and yarn rolls, and by setting RFID readers on sorting and packing lines, the present invention can record the roll material information into the identification code of the cartons during packing, so that the cartons and the inner roll materials are bound together; when the transfer mechanism transfers the cartons, the transfer mechanism can read the packing type of the cartons through the identification code, and place the cartons on the corresponding buffer conveyor belt based on the packing type, so as to achieve the effect of classifying and storing the cartons; on the other hand, when the present invention repacks the cartons that are not full, the sixth RFID reader can read the identification code of the cartons that are not full, and the packing mechanism can grab the roll materials on the production line according to the roll material information corresponding to the identification code, so that the type of the grabbed roll materials and the roll materials in the cartons that are not full can be consistent, thus ensuring the stability of the present invention during repacking;

[0037] Therefore, the present invention can realize the packing and replenishment of rolls of different packaging types, effectively improving the packing efficiency and packing effect of yarn rolls. Attached Figure Description

Detailed Implementation

[0046] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0047] Example. An RFID-based roll material sorting and packing production line is configured as follows: Figure 1 As shown, it includes a conveyor line 1, on which several rolls 2 are distributed. Each roll 2 is equipped with a first identification code. The outside of the conveyor line 1 is provided with a weighing and diameter measuring station 3, an inspection station 4, a film suction and film covering station 5, a sorting station 6 and a boxing station 7 in sequence along the conveying direction.

[0048] The roll 2 is used to support and transport the roll material;

[0049] The weighing and diameter measuring station 3 is used to detect the outer diameter and / or weight of the roll material, and the detection result is entered into the control system as the roll material specification through the first identification code;

[0050] The inspection station 4 is where the quality of the roll material is assessed or inspected manually, and the results are entered into the control system via the first identification code, so that subsequent stations can directly read the quality and specifications of the roll material corresponding to the roll material 2 via the first identification code.

[0051] The film suction and wrapping station 5 is used to wrap the outer packaging film of the roll material;

[0052] The sorting station 6 includes a feeding conveyor belt 8 located in the middle of the conveyor line 1. Three circulating discharge components are connected to one side of the feeding conveyor belt 8. The three circulating discharge components are arranged at intervals along the conveying direction of the feeding conveyor belt 1. Each circulating discharge component corresponds to a roll of material of a certain quality.

[0053] The circulating discharge assembly includes a forward circulating conveyor belt 9, which is perpendicular to the feed conveyor belt 8. One end of the forward circulating conveyor belt 9 is connected to the feed conveyor belt 8, and the other end of the forward circulating conveyor belt 9 is connected to a first discharge conveyor belt 10. A reverse circulating conveyor belt 11 is provided on one side of the forward circulating conveyor belt 9. The reverse circulating conveyor belt 11 and the forward circulating conveyor belt 9 have opposite conveying directions. Both ends of the reverse circulating conveyor belt 11 are connected to the forward circulating conveyor belt 9 via a turning conveyor belt 12. The forward circulating conveyor belt 9, the turning conveyor belt 12 and the reverse circulating conveyor belt 11 form a circular circulation line after being connected end to end.

[0054] The feeding conveyor belt 8 is used to identify the quality of the roll material via the first identification code, and to feed the roll material into the corresponding circulating discharge assembly according to the quality of the roll material.

[0055] The circulating discharge assembly is used to identify the quality and specifications of the roll material via the first identification code, and to control the roll material to enter the first discharge conveyor belt 10 or move continuously along the circulating line according to the quality and specifications of the roll material.

[0056] The packing station 7 includes a packing mechanism 13, which is a conventional mechanical gripper used for clamping and moving roll materials. During use, the mechanical gripper can pick up the roll material from the external conveyor belt and place it sequentially into the carton. A packaging conveyor belt 14 is located on one side of the packing mechanism 13, outside the conveyor line 1. Two packing conveyor belts 15 are located between the packaging conveyor belt 14 and the sorting station 6. Each packing conveyor belt 15 has a packing mechanism 13 on one side. One end of the packing conveyor belt 15 is connected to the packaging conveyor belt 14, and the other end is connected to a transfer conveyor belt 16 located in the middle of the conveyor line 1. The transfer conveyor belt 16 is externally connected to the first discharge conveyor belt 1. 0. A sealing mechanism 17 is provided in the middle of the sealing conveyor belt 14. The sealing mechanism 17 is a conventional sealing facility used to close the top cover of the carton and seal it with tape. The end of the sealing conveyor belt 14 forms a transfer station 18. A transfer mechanism 19 is provided on one side of the transfer station 18. The transfer mechanism 19 is a conventional transfer robot used to clamp and move the carton. When in use, the transfer robot can pick up the carton and stack it on the pallet. A return conveyor belt 20 and multiple buffer conveyor belts 21 are provided on the outside of the transfer mechanism 19. The end of the return conveyor belt 20 is connected to the sealing conveyor belt 14. A manual carton replenishment station 22 is formed on one side of the return conveyor belt 20 or the sealing conveyor belt 14.

[0057] The first discharge conveyor belt 10 is used to feed the roll material into the transfer conveyor belt 16;

[0058] The transfer conveyor belt 16 is used to identify the quality and specifications of the roll material by the first identification code, and the packing mechanism 13 packs the roll material into boxes according to the identification result.

[0059] The packaging conveyor belt 14 is used to package the cartons after they have been packed and transport them to the transfer station 18.

[0060] The transfer station 18 is used to identify the quality and specifications of the roll material by the first identification code, and the transfer mechanism 19 transfers the carton to the pallet of the corresponding buffer conveyor belt 21 according to the identification result, or transfers the unfilled carton on the top of the pallet to the return conveyor belt 20.

[0061] The return conveyor belt 20 is used to transport cartons that are not fully loaded with material to the packaging conveyor belt 14;

[0062] The manual refill station 22 is used to manually place rolls of material into cartons that are not fully filled with rolls of material.

[0063] The turning conveyor belt 12 is provided with a guide plate that cooperates with the roll 2. The guide plate is used to guide the roll 2 so that the roll 2 moves into or out of the turning conveyor belt 12 along the guide plate.

[0064] A first guide component 23 is provided at the connection between the forward circulating conveyor belt 9 and the first discharge conveyor belt 10. Three second guide components 24, which cooperate with the circulating discharge component, are distributed at intervals on the feeding conveyor belt 8. Both the first guide component 23 and the second guide component 24 are used to control the conveying direction of the roll 2, so that the roll continues to be conveyed forward or turns. Each first guide component 23 is provided with a first RFID reader 25 that cooperates with the first identification code on one side. Each second guide component 24 is provided with a second RFID reader 26 that cooperates with the first identification code on one side. Both the first RFID reader 25 and the second RFID reader 26 are used to read the quality and specifications of the rolled material on the roll 2 through the first identification code.

[0065] The first guide assembly 23 and the second guide assembly 24 have the same structure, both including a swing frame. One end of the swing frame is rotatably connected to the feed conveyor belt 8 or the first discharge conveyor belt 10. One side of the swing frame forms a guide surface for guiding the conveying direction of the roll 2. A drive component is connected to the outside of the swing frame. The drive component can be a telescopic rod. When the telescopic rod is in the retracted state, the guide surface does not change the conveying direction of the roll 2, so that the roll 2 continues to be conveyed forward along the current conveyor belt. When the telescopic rod is in the extended state, the guide surface intercepts and guides the roll 2, so that the roll 2 turns and enters another conveyor belt.

[0066] Two second discharge conveyor belts 27 are connected to one side of the feeding conveyor belt 8. The second discharge conveyor belts 27 correspond to rolls of material of the same quality and specification, so that the roll specifications do not need to be screened during later packing. The circulating discharge component and the second discharge conveyor belts 27 are arranged at intervals along the conveying direction of the feeding conveyor belt 8. The feeding conveyor belt 8 is provided with a third guide component 28 that cooperates with the second discharge conveyor belts 27. The structure and function of the third guide component 28 are the same as those of the first guide component 23. A second RFID reader 26 that cooperates with the identification code is also provided on one side of the third guide component 28. The end of the second discharge conveyor belt 27 is connected to the transfer conveyor belt 16.

[0067] The number of transfer conveyor belts 16 is two sets, and the two sets of transfer conveyor belts 16 are arranged side by side. One set of transfer conveyor belts 16 corresponds to the second discharge conveyor belt 27, and the other set of transfer conveyor belts 16 corresponds to the first discharge conveyor belt.

[0068] It also includes a carton conveyor belt 29 located between the transfer conveyor belt 16 and the packing conveyor belt 15. The carton conveyor belt 29 and the packing conveyor belt 15 are arranged perpendicular to each other. The front end of the carton conveyor belt 29 along the conveying direction is provided with an opening mechanism. This opening mechanism is a conventional carton opening mechanism, which is used to open the folded carton and send it into the carton conveyor belt 29. The packing conveyor belt 15 is connected to the carton conveyor belt 29 at the end away from the sealing conveyor belt 14.

[0069] A lifting and traversing mechanism is provided on the carton conveyor belt 29 on one side of the packing conveyor belt 15. The lifting and traversing mechanism is used to lift the carton and transport it into the packing conveyor belt 15 after the carton has moved into place. A lifting and traversing mechanism is provided on the sealing conveyor belt 14 on the other side of the packing conveyor belt 15. The lifting and traversing mechanism is used to lift the carton and transport it into the sealing conveyor belt 14 after the carton has moved into place.

[0070] The packing conveyor belt 15 forms a packing position at one end near the carton conveyor belt 29. A top rod 30 and a baffle 31 are respectively provided on both sides of the packing position. The lower ends of the top rod 30 and the baffle 31 are connected to telescopic components. The baffle 31 is used to limit one end of the carton during packing, and the top rod 30 is used to push the other end of the carton during packing, so that the carton remains tilted during the packing process. When the carton is tilted, the roll material will be stacked with the inner wall of one side of the carton as the support surface after packing, thereby preventing the roll material from tipping over after packing.

[0071] Each packaging conveyor belt 14 is equipped with a photoelectric switch on one side of each packing conveyor belt 15. The photoelectric switch is used to detect whether there is a carton on the packaging conveyor belt 14 before the packing conveyor belt 15 sends the carton into the packaging conveyor belt 14, thereby avoiding collisions of the carton during the alternating conveying process.

[0072] The cardboard box is equipped with a second identification code, and both the first and second identification codes are RFID tags. The packing conveyor belt 15 is equipped with a third RFID reader 32 that works in conjunction with the second identification code, and the transfer station 18 is equipped with a fourth RFID reader 33 that also works in conjunction with the second identification code. The third RFID reader 32 is used to input the quality and specifications of the packed rolls into the control system via the second identification code, ensuring that each second identification code contains the quality and specifications of all rolls within the cardboard box. The fourth RFID reader 33 is used to read the quality and specifications of the rolls within the cardboard box via the second identification code and input the cardboard box's stacking information into the control system via the second identification code, thus linking the information of each cardboard box on each pallet. Specifically, this linking method involves numbering the cardboard boxes on a pallet basis, so that each cardboard box on any pallet is associated with a specific number. This allows the RFID reader to obtain the quantity of cardboard boxes on the corresponding pallet by reading the second identification code of any cardboard box.

[0073] When a batch of roll material is packed, if the number of cartons on any pallet or the number of rolls in any carton does not meet the requirements, the sorting station 6 and the packing station 7 directly complete the packing process of the roll material and put the carton and the pallet into the temporary storage area for temporary storage. When the next batch of roll material is packed, the operator first puts the pallet in the temporary storage area together with the carton into the buffer conveyor belt 21. After reading the second identification code of any carton on the pallet, the buffer conveyor belt 21 replenishes the pallet through the packing station 7 until the pallet is packed.

[0074] The transfer conveyor belt 16 is equipped with a fifth RFID reader 34 that works with the first identification code. The buffer conveyor belt 21 has a bidirectional conveying function and is equipped with a sixth RFID reader 35 that works with the second identification code. When the operator puts the unpacked pallet into the buffer conveyor belt 21, the sixth RFID reader 35 reads any second identification code on the pallet and obtains the carton information corresponding to the pallet. Then, the buffer conveyor belt 21 transports the pallet to the clamping position, and the transfer mechanism 19 picks up the carton that is not fully loaded on the top of the pallet and sends it into the return conveyor belt 20, so that the carton can be repacked at the packing station 7.

[0075] The specifications of the roll material are the outer diameter or weight of the roll material. When the specifications of the roll material are the outer diameter, the control system is manually set according to the range of the outer diameter of the roll material to determine the packaging type. When the roll material moves continuously in the circulation line, the control system judges the quality and specifications of the roll material in the current circulation line according to the packaging type. If the number of roll materials in the current circulation line that meet the same packaging type reaches the box quantity, the control system controls the circulation discharge component to send all the corresponding roll materials into the first discharge conveyor belt 10. Otherwise, the roll material continues to move in the circulation line.

[0076] When the roll material specification is the roll material weight, the control system is manually set to the total weight of the roll material in the carton. When the roll material moves continuously in the circulation line, the control system judges and filters the quality and specifications of the roll material in the current circulation line according to the remaining carton weight in the carton during the packing process, so as to select the roll material that meets the remaining carton weight and send it into the first discharge conveyor belt 10.

[0077] The manual box replenishment station 22 is equipped with a seventh RFID reader 36 that works with the second identification code. When in use, the operator reads the second identification code on the carton through the seventh RFID reader to obtain the roll material information inside the carton. Then, the sorting station 6 transports the corresponding roll material to the transfer conveyor belt 16 according to the roll material information. The boxing mechanism 13 then clamps the roll material from the sorting station 6 to the carton conveyor belt 29 or other positions that can be reached by the operator. Finally, the operator puts the roll material into the carton and then reseals the carton and places it on the pallet in the same way.

[0078] In this embodiment, after the roll material is loaded, the roll 2 is conveyed forward via the conveyor line 1. During the conveying process, the outer diameter and weight of the roll material are first detected at the weighing and diameter measuring station 3. Then, the operator at the inspection station 4 visually inspects the surface of the roll material for defects such as fading, uneven thickness, and surface stains, and verifies the quality of the roll material based on the observation results. After inspection, the roll material is then fitted with packaging film at the film suction and film covering station 5, and then enters the feeding conveyor belt 8 via the conveyor line 1.

[0079] After the roll 2 enters the feeding conveyor belt 8, it is driven forward by the feeding conveyor belt 8. Each time the roll 2 moves to the position of the second guide component 24 or the third guide component 28, the corresponding second RFID reader 26 reads the roll information through the first identification code at the bottom of the roll 2. If the quality of the roll corresponds to the current circulating discharge component or the second discharge conveyor belt 27, the second guide component 24 or the third guide component 28 will move to drive the roll 2 into the current circulating discharge component or the second discharge conveyor belt 27. If the quality of the roll does not correspond, the feeding conveyor belt 8 will continue to drive the roll 2 forward.

[0080] When the roll 2 enters the second discharge conveyor belt 27, it is directly driven by the second discharge conveyor belt 27 into the subsequent transfer conveyor belt 16 to complete the boxing operation. When the roll 2 enters the circulating discharge assembly, it is first driven by the forward circulating conveyor belt 9 to move to the first guide assembly 23, and the first RFID reader 25 on one side of the first guide assembly 23 reads the roll information. If the roll information meets the boxing requirements, the first guide assembly 23 switches to the open state so that the roll 2 directly enters the first discharge conveyor belt 10 and enters the subsequent transfer conveyor belt 16 along the first discharge conveyor belt 10 to complete the boxing operation. If the roll information does not meet the packing requirements, the first guide component 23 switches to the closed state, so that the roll 2 is driven by the forward circulating conveyor belt 9 and enters the turning conveyor belt 12 along the guide surface. Then, through the cooperation of the turning conveyor belt 12 and the guide plate, it enters the reverse circulating conveyor belt 11. The reverse circulating conveyor belt 11 drives the roll 2 back to the front end of the forward circulating conveyor belt 9, waiting for the next recognition.

[0081] With the above coordination, the circulating discharge component can sequentially read the information of each roll and input it into the control system. The control system then filters and conveys the rolls in the sorting station 6 based on the packing requirements of the subsequent packing station 7. Rolls that cannot be packed quickly can continue to move and wait in the circulating discharge component until the quantity of the rolls of that type reaches the packing requirements, or the specifications of the rolls meet the current packing requirements, and then they are conveyed to the next stage, thereby achieving rapid packing at the subsequent packing station 7.

[0082] After the roll material enters the transfer conveyor belt 16 via the first discharge conveyor belt 10, the fifth RFID reader 34 first verifies the roll material information to confirm that the roll material matches the carton to be packed. Then, the packing mechanism 13 clamps the roll material and places it on the carton to complete the packing function. During the packing process, the carton is tilted by the push rod 30, which allows the roll material to maintain its tilted position with the carton and be stacked vertically along the height direction, thereby preventing the roll material from tipping over after being pushed by the cardboard.

[0083] After the carton is packed, the top rod 30 retracts and the baffle 31 descends to a low position, causing the carton to fall back onto the packing conveyor belt 15. Then, the packing conveyor belt 15 carries the carton into the sealing conveyor belt 14, and the sealing conveyor belt 14 transports the carton to the transfer station 18. During the transport process, the carton is sealed by the sealing mechanism 17, which closes the top cardboard of the carton and seals it with tape.

[0084] Once the cartons are moved to transfer station 18, the fourth RFID reader 33 reads the second identification code on the cartons to obtain the roll material information. Then, the transfer mechanism 19 transfers the cartons to the corresponding buffer conveyor belt 21 according to the roll material information, and stacks the cartons on pallets. When the number of cartons on a pallet reaches a threshold, the buffer conveyor belt 21 transports the pallet to the location to be handled, and then a forklift removes the pallet and sends it to the warehouse for storage. At the same time, the operators put new pallets back into the buffer conveyor belt 21 for subsequent packing operations.

[0085] When a batch of roll material is completed, if the remaining roll material of a certain packaging type cannot meet the requirements for one packing, or if the number of cartons on the pallet does not reach the threshold, the sorting station 6 and packing station 7 will first pack the roll material in the same way and stack it on the pallet. Then, a forklift will place the pallet into the designated storage area. When the next batch of roll material starts production, the operator will first use a forklift to put the pallet along with the cartons back to the corresponding buffer conveyor belt 21 and read the packing information of the cartons corresponding to the pallet using the sixth RFID reader 35. The buffer conveyor belt 21 will then transport the pallet to the operating position of the transfer mechanism 19. The transfer mechanism 19 will then remove the top cartons from the pallet and place them into the return conveyor belt 20, allowing the unfilled cartons to enter the manual replenishment station 22 along the return conveyor belt 20.

[0086] When an incomplete carton enters the manual replenishment station 22, it is opened manually. Simultaneously, the seventh RFID reader 36 reads the second identification code on the carton to obtain the corresponding roll material information. Then, the packing mechanism 13 places the corresponding quantity and type of roll material into the manual replenishment station 22 or other locations accessible to operators based on this roll material information, and the manual packing is completed. After the operator fills the carton, the carton undergoes subsequent sealing and stacking operations according to the normal process. The pallet, once full, is then sent to the warehouse in the usual manner, thus completing the reuse of each incomplete carton in sequence.
