Description

Technical Field

[0001] The invention belongs to the technical field of fertilizer storage automation management, and in particular relates to an automatic material in-and-out warehouse detection system based on RFID tag management. Background Art

[0002] In the process of fertilizer logistics warehousing management, in order to improve the efficiency of warehousing management, RFID tags with cargo information are also pasted on the cargo and pallets, so that when entering and leaving the warehouse, the cargo information can be quickly and accurately collected by scanning the paper RFID tags, thereby improving management efficiency; this process usually includes coding or labeling the cargo, and then reading the cargo information by manual scanning or visual recognition at each link to determine the cargo entry and exit status. However, when these traditional detection methods are used in working environments with poor environmental conditions such as workshops, such as large storage places such as fertilizers, there will be problems with detection accuracy, resulting in large errors. In particular, when dealing with stacked cargo, manual single scanning and identification are still used, which is not only inefficient, but also requires a lot of manual operations. Therefore, problems such as misreading, missed reading, repeated reading and misjudgment occur frequently, which directly affects the accuracy of cargo entry and exit statistics.

[0003] On the other hand, in order to solve the problem of paper RFID tags being easily damaged, plastic shell RFID tag cards are used to be pasted on goods and pallets, and then the pallets and goods are scanned and registered respectively. At present, RFID tag cards are basically affixed to pallets manually, which requires manual adjustment one by one, finding the labeling area on the pallet and goods, and then gluing and labeling, and then taking the pallet away. Moreover, in large-scale warehousing, the number of pallets required for transit and storage is large, and labeling is relatively frequent. The long hours of work of the staff lead to high labor intensity and inevitable mistakes. It is not only time-consuming and labor-intensive, but also causes increased labor costs and low work efficiency. Therefore, the development of a management and detection equipment that can replace manual labor and perform automatic labeling and code scanning is the key to solving the problem. Summary of the invention

[0004] The present invention provides a material automatic in-and-out warehouse detection system based on RFID tag management.

[0005] The present invention is achieved through the following technical solutions: It includes a roller conveyor, a goods rectifying mechanism, an automatic card pasting mechanism, an in-warehouse code scanning and detection device, an orientation adjusting mechanism, an out-warehouse code scanning and detection device, and a universal ball roller conveyor. Roller conveyors are respectively arranged at the in-warehouse entrance and the out-warehouse entrance of the warehouse. The ends of each roller conveyor are connected to the universal ball roller conveyor. The goods rectifying mechanism, the automatic card pasting mechanism, and the in-warehouse code scanning and detection device are sequentially arranged on the roller conveyor at the in-warehouse entrance. The orientation adjusting mechanism and the out-warehouse code scanning and detection device are sequentially arranged on the roller conveyor at the out-warehouse entrance. Among them, both the in-warehouse code scanning and detection device and the out-warehouse code scanning and detection device include a dust removal mechanism, an equipment frame, a scanner group, a supplementary light group, an RFID reader / writer, a camera group, a driving member, a lifting carrier plate, and a dust removal mechanism. The equipment frame is arranged in a U-shaped structure and straddles the roller conveyor. On the two side walls of the equipment frame straddle, the supplementary light group, the scanner group, the RFID reader / writer, and the camera group are sequentially arranged from the feeding end to the discharging end. The supplementary light group, the scanner group, and the camera group are arranged vertically. The driving member is arranged at the middle section of the equipment frame and is directly below the roller conveyor. A lifting carrier plate is arranged on the top of the driving member. A small weighing scale is arranged on the top of the lifting carrier plate, or a small weighing scale is arranged between the driving member and the lifting carrier plate. A lifting window for the free lifting of the lifting carrier plate is arranged on the roller conveyor. A dust removal mechanism is arranged at the feeding end of the equipment frame, and the dust removal mechanism straddles the roller conveyor.

[0006] The beneficial effects of the present invention are as follows: 1. It has the function of automatically transporting goods, and automatically regularizes pallets and goods to ensure the consistency of transportation, so as to facilitate the labeling operation; it can weigh the weight of goods, eliminate unqualified goods, can check the labeling situation, eliminate goods and pallets with missing RFID label cards, and can automatically, quickly, and accurately collect goods and pallet information, further improving management standardization; 2. It uses automated equipment to replace the operations of manually taking cards, applying glue, and pasting. Each time an RFID label card is issued, effectively solving the problem of the large labor intensity caused by the long-term labor of staff, saving time and effort, and having strong practicability; it greatly improves the card issuing and pasting efficiency of RFID label cards, not only applicable to the labeling requirements of a large number of pallets and goods, but also meeting the labeling requirements of a small number of pallets, reducing labeling errors and labor costs while also improving work efficiency; 3. It can automatically identify and scan the RFID tags and RFID tag cards on the pallets and goods entering and leaving the warehouse, and weigh the total weight of the goods on the pallet at the same time. It adopts a combination of a scanner group, an RFID reader and a camera group to make the scanning more complete, improve the fault tolerance rate, and accurately obtain the actual cargo information of the cargo unit. In addition, when the actual cargo information is inconsistent with the target cargo information, it will suspend instructing the handling mechanism to enter and exit the warehouse. By automatically identifying whether the actual cargo information is consistent with the target cargo information, the cargo units with inconsistent actual cargo information and target cargo information can be screened out, thereby avoiding the entry and exit of goods with inconsistent actual cargo information and target cargo information, ensuring the accuracy and traceability of the goods entering and leaving the warehouse, and improving the accuracy of entering and leaving the warehouse and cargo transportation.

[0027] The working method of the warehousing detection of the present invention is as follows: 1. According to the thickness of a single RFID tag card, the size of the RFID tag card mentioned in the technical solution of the present application is 5~10cm×3~10cm×0.1~3cm, and the automatic card issuing machine 13 is adjusted to make the card outlet 22 of the automatic card issuing machine 13 match the thickness of the single RFID tag card to prevent multiple cards from being issued at one time or card issuance failure. The RFID tag cards are stacked in the card storage box with the front side facing down and the back side facing up according to certain requirements, and then the automatic card issuing machine 13 is started to automatically issue only one RFID tag card each time; 2. After the RFID tag card discharged from the card outlet 22 of the automatic card issuing machine 13 enters the card guide slot 15, its lower end will automatically adjust to a vertical posture under the guidance of the front wall of the card guide slot 15 and the guide plate 16, and then automatically fall along the card guide slot 15 to the bottom of the card guide slot 15; at this time, the driving member 3 controls the baffle 18 to enter the window 21 upward along the card guide slot 15 to ensure that the RFID tag card is in a vertical state and prevent the RFID tag card from sliding out of the window 21 under the action of gravity; then, the driving member 3 first controls the adsorption plate to enter the through hole 20 to adsorb the RFID tag card, and the driving member 3 controls the baffle 18 to exit the window 21 downward along the card guide slot 15, and the driving member 3 continues to control the adsorption plate adsorbed with the RFID tag card to pass through the window 21; 3. The driving member 3 of the automatic glue coating mechanism starts to perform lifting movement, and controls the glue dispensing port of the automatic glue dispensing machine 14 to be flush with the RFID tag card. The driving motor 26 drives the telescopic driving member 3 to move horizontally on the guide rail 24 through the driving rack 25, so that the glue dispensing port of the glue dispensing machine is aligned with the RFID tag card. The telescopic driving member 3 performs a telescopic movement, so that the glue dispensing port of the glue dispensing machine contacts the back of the RFID tag card, and the glue dispensing machine starts to perform glue coating work; Fourth, according to the gluing requirements, the driving member 3 starts to move up and down, and the driving motor 26 drives the telescopic driving member 3 to move horizontally on the guide rail 24, so that the glue of the glue dispenser is evenly applied on the back of the RFID tag card, waiting for the RFID tag card to be attached. At this time, the gluing work has been completed, the glue dispenser is controlled to stop, and the driving member 3 and the telescopic driving member 3 are reset; 5. The goods to be labeled or the pallets with goods on them are moved from the feeding end to the discharging end of the roller conveyor 1 in a certain order. First, under the action of the primary correction mechanism, the direction of the oblique goods or the pallets with goods on them is automatically adjusted during the conveying process, and then they are moved with the roller conveyor 1 to the position of the carrier plate 10 behind the correction rear plate 7; Sixth, after the goods or the pallet with goods on it reaches the position of the carrier plate 10 of the goods correction mechanism 4, the driving member 3 is lifted, so that the carrier plate 10 holds up the goods or the pallet with goods on it, and the weight sensor 11 performs weight detection on the goods in the pallet or box frame to achieve the purpose of weighing. When the labeling area of ​​the goods or the pallet with goods on it is not on the same side as the automatic card issuing machine 13, the hollow rotating platform 9 rotates to adjust the labeling area of ​​the goods or the pallet with goods on it to be not on the same side as the automatic card issuing machine 13, so as to facilitate subsequent labeling; after the adjustment is completed, the driving member 3 descends and resets, so that the goods or the pallet with goods on it descends and continues to move with the roller conveyor 1 to the position of the automatic card issuing machine 13; 7. When the labeling area of ​​the goods or the pallet on which the goods are placed is opposite to the RFID tag card coated with glue on the automatic card sticking mechanism 12, the roller conveyor 1 stops, and the pushing mechanism pushes on the side of the goods or the pallet on which the goods are placed to control the driving member 3 to continue to extend and contact the goods, so that the RFID tag card on the vacuum adsorption plate 17 is attached to the goods, and then the vacuum adsorption plate 17 is controlled to exhaust and remove the adsorption force, thereby realizing the automatic card issuance and labeling of the RFID tag card, and finally the driving member 3 is controlled to exit the window 21 and the through hole 20 to reset, and the driving member 3 controls the baffle 18 to enter the window 21 upward along the card guide groove 15, and the pushing mechanism is reset to wait for the next card issuance and labeling, while the roller conveyor 1 continues to drive the goods or the pallet on which the goods are placed to move, and finally the universal ball roller conveyor 2 distributes it to each conveying branch line; 8. During the card issuance process, if the RFID tag is stuck in the card guide slot 15 and cannot fall automatically, the driving member 3 behind the guide plate 16 is started, and the driving member 3 pushes the guide plate 16 to rotate, thereby pushing down the RFID tag to solve the problem of the RFID tag being stuck; before sticking the RFID tag, the carrier plate 10 and the weight sensor 11 cooperate to weigh the goods or the pallet with the goods, and when the weight of the goods or the pallet with the goods does not meet the requirements, an alarm is sounded, and when the unqualified goods or the pallet with the goods are transported to the automatic card sticking mechanism 12, the automatic card sticking mechanism 12 does not perform the labeling operation, but directly transports the unqualified goods or the pallet with the goods to the universal ball roller conveyor 2, and the universal ball roller conveyor 2 distributes and transports them to the unqualified product conveying branch line; 9. The labeled goods or pallets with goods are transported to the warehouse entry scanning detection device 27, which scans and identifies the RFID tag card information on the goods or pallets with goods, and uploads the information one by one to the pallet management control center for management. Finally, the goods or pallets with goods are placed in an orderly manner at the designated location of the warehouse for storage.

[0028] The outbound detection working method of the present invention is as follows: 1. The pallet with stacked goods is taken out from the shelf or the designated position by a forklift or other handling equipment and placed on the roller conveyor 1; it should be noted that the goods on the pallet must be stacked in order, and the RFID tags of each goods are facing outward and unobstructed; the roller conveyor 1 transports the pallet and the goods to the feeding end of the adjustment mechanism 44, and the calibration camera 51 set at the station takes pictures of the goods, and the background manually or by using an automatic control system checks the photographed goods information to check whether the RFID tag on the goods is photographed; Second, if the RFID tag is not photographed, the direction adjustment mechanism 44 needs to be activated to adjust the direction of the pallet to ensure that the RFID tag on the goods can be scanned or photographed at the scanner group 30 station; if the RFID tag is photographed, there is no need to activate the direction adjustment mechanism 44 to adjust the direction of the pallet, but directly transport the pallet to the scanner group 30 station for scanning and detection; the specific method of the direction adjustment mechanism 44 to adjust the direction of the pallet is as follows: Before conveying the pallet, the driving member 3 controls the steering arm claw 48 to descend, and the lower end of the steering arm claw 48 passes under the roller of the roller conveyor 1 and is close to the edge of the roller conveyor 1; when the pallet runs to the bottom of the steering mechanism 44, it is detected by the position detection sensor 50 there, the roller conveyor 1 stops, and each driving motor 26 drives each cantilever 47 to move close to the pallet through the screw rod 49 and finally touches the pallet. At this time, the driving member 3 is started to control the steering arm claw 48 to rise, so that the lower part of the steering arm claw 48 supports the pallet. The bottom of the pallet is then controlled to continue to rise, and the pallet is lifted from the roller conveyor 1. The hollow rotating platform 9 is then started to rotate 90 degrees or 180 degrees, so that the RFID tag on the goods faces the scanner group 30. Finally, the driving member 3 controls the arm claw 48 to descend, and the pallet is unloaded on the roller conveyor 1. Each drive motor 26 drives each cantilever 47 to move the principle pallet in the opposite direction through the screw rod 49, and the roller conveyor 1 continues to run, and the pallet and the goods are transported to the scanner group 30 for scanning and identification; 3. When the pallet moves to the bottom of the dust removal mechanism 36, that is, when it is in the inner shield 38 of the dust removal mechanism 36, it is detected by the position detection sensor 50 there, the roller conveyor 1 stops, and the end cover plates 43 at the front and rear ends of the dust removal mechanism 36 fall, so that the inner shield 38 and the end cover plates 43 become a closed space, and the compression fan 41 blows air to the pallet and the goods through the nozzle 39 to remove dust, blows off the dust on the pallet and the goods, and the dust is sucked out by the exhaust fan 42 through the exhaust port 40, thereby solving the problem that the RFID tag on the goods cannot be scanned due to dust blocking; when the dust removal is completed, the end cover plate 43 rises, and the roller conveyor 1 transports the pallet and the goods to the scanner group 30 and the RFID reader 32 for scanning and detection. After the dust removal mechanism 36 removes dust from the goods and then scans and detects the goods, it can avoid the phenomenon of data misidentification or non-recognition caused by dust factors in workshops and warehouses, and at the same time realizes continuous detection and improves detection efficiency.

[0029] 4. When the pallet runs to the bottom of the equipment frame 29 and is directly above the lifting plate 34, it is detected by the position detection sensor 50 there, the roller conveyor 1 stops, the driving member 3 lifts the lifting plate 34, and the lifting plate 34 lifts the pallet. The small floor scale 35 weighs the weight of the goods on the pallet to facilitate the grasp of the weight information of the outbound goods and compare the information at the time of entry to ensure that the previous and subsequent information are consistent. When any differences are found, they can be discovered and checked in time; when the weighing is completed, the driving member 3 descends to unload the pallet onto the roller conveyor 1, and the roller conveyor 1 continues to convey it.

[0030] 5. In the process of conveying the above-mentioned pallet from entering the equipment frame 29 to leaving, the scanner group 30 on both sides of the equipment frame 29 first scans the RFID tags on the first entering goods one by one. When the first half of the goods are scanned, the pallet is directly above the lifting plate 34, and the weighing operation is performed at this time. During this process, the RFID reader 32 reads and writes and identifies the RFID tag card on the pallet. After the weighing is completed, the pallet moves with the roller conveyor 1, and finally the camera group 33 photographs the RFID tags on the goods one by one until they are conveyed out of the scanning detection device. In the above process, when any of the scanner group 30, the RFID reader 32, and the camera group 33 has a scanning error, an alarm can be issued to prompt the management personnel to check the situation in time to avoid the occurrence of errors in the delivery of goods.

[0031] 6. During the transportation process of the above-mentioned pallet from entering the equipment frame 29 to leaving, the scanner group 30 and the camera group 33 can fully scan each RFID tag and upload the RFID tag information to the background data management center, which is analyzed by the system to achieve double verification, avoid missed scanning and wrong scanning, and ensure the accuracy of information obtained by scanning; on the other hand, through the camera group 33 shooting, it can be timely known that the RFID tag is blocked or damaged, so as to facilitate timely decontamination or replacement. When the goods are set with an RFID tag card, there is no need to start the scanner group 30 to scan the code, but directly read and write through the RFID reader 32, and then shoot with the camera group 33 to timely know whether the RFID tag card is damaged, so as to facilitate replacement.
