Description

Technical Field

[0001] The utility model relates to the field of intelligent shelves, and particularly relates to an intelligent shelf for offline orders. Background Technique

[0002] In today's consumption trend of pursuing personalization and customization, intelligent experience production lines have emerged. It not only integrates advanced automation and intelligent technologies, but also cleverly transforms the production process into a unique user experience, allowing users to witness and participate in the birth process of their customized products.

[0003] In the design of intelligent experience production lines, in order to fully meet the diverse needs of users, especially for different scenarios such as self-use and gift-giving, the system also provides flexible ways to pick up goods. That is, users can either choose to experience in person offline and directly pick up customized products, or choose to have them mailed to a designated address to enjoy convenient delivery services.

[0004] Since all customized products originate from the same intelligent production line and are output through a single finished product transportation line, the production line needs to achieve effective diversion of finished products without interfering with the production process. And for orders selected for offline self-pickup, the production line needs to ensure that the whole process from production to the self-pickup station is linear and visual, so that users can witness and enjoy this unique experience. At the same time, the design of this process also needs to ensure that it will not cause any obstruction or delay to the output of finished products selected for mailing to the background collection area.

[0005] However, the existing production lines cannot meet such requirements of flexibility and intelligence. The design purpose of existing production lines is to improve production efficiency, and their production line designs are mainly focused on high efficiency, with poor visualization. Moreover, usually only one type of product can be produced on the same production line, and the finished products are collected in a unified manner, gathering all products in one place and then distributed through subsequent manual or semi-automatic sorting processes. This design not only cannot meet the immediate diversion requirements of intelligent experience production lines, but also cannot provide users with the opportunity to watch the entire production process of products and the unique experience of personally receiving their customized products. Content of the Utility Model

[0006] The utility model aims to provide an intelligent shelf for offline orders to solve the technical problem that the existing production line cannot automatically divert offline self-pickup and mailed orders without interference.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: An intelligent shelf for offline orders includes a transmission mechanism for uniformly outputting goods, a transfer manipulator for transferring self-picked goods, and a buffer shelf for storing self-picked goods; the buffer shelf is installed on one side of the transmission track of the transmission mechanism; the working area of the transfer manipulator spans between the transmission mechanism and the buffer shelf;

[0008] The conveying mechanism includes conveyor belts for transporting goods. There are two conveyor belts, which respectively support both sides of the bottom of the goods.

[0009] The transfer manipulator includes a transfer slide rail, a sliding flat plate, and a gripper assembly for grasping goods. The two ends of the transfer slide rail are respectively located above the conveyor belt and the buffer shelf. The sliding flat plate is slidably connected to the transfer slide rail. The gripper assembly is installed on the sliding flat plate, and a lifting cylinder is further provided between the sliding flat plate and the gripper assembly.

[0010] Below the conveyor belt in the area under the transfer slide rail, there is a blocking cylinder for intercepting goods. The blocking cylinder is located at the center position between the two conveyor belts, and the blocking cylinder extends vertically upward. When the blocking cylinder extends, the end of its telescopic end is higher than the conveyor belt; when the blocking cylinder contracts, the end of its telescopic end is lower than the conveyor belt.

[0011] The principle and advantages of this solution are as follows: In actual application, the intelligent shelf uniformly receives finished products from the production line through the conveying mechanism, that is, the conveyor belt. These finished products are continuously conveyed at a certain interval on the conveyor belt, ready for the next step of sorting; when the target goods to be picked up offline reach the predetermined position, the blocking cylinder located under the conveyor belt will extend, and the end of its telescopic end is higher than the surface of the conveyor belt, thereby intercepting the goods and preventing it from continuing to be conveyed forward to the mailing order collection area.

[0012] At this time, the transfer manipulator slides on the transfer slide rail through the sliding flat plate to the upper part of the intercepted goods, and uses the lifting cylinder to adjust the height of the gripper assembly so that it can accurately grasp the goods; subsequently, the transfer manipulator transfers the grasped goods to the buffer shelf for subsequent users to pick up offline; while the transfer manipulator is operating, the goods not intercepted on the conveyor belt continue to be conveyed forward and finally reach the mailing order collection area, realizing the automatic processing of mailing orders.

[0013] Through the coordinated work of the blocking cylinder and the transfer manipulator, efficient and automatic sorting of offline pick-up and mailing orders is achieved, avoiding the tediousness and inefficiency of manual sorting in traditional production lines; the entire sorting process is carried out on the conveyor belt, and users or staff can clearly see the flow and processing status of the goods, realizing the visualization and transparency of the production process; effectively solving the technical problem that the existing production line cannot achieve automatic sorting of offline pick-up and mailing orders, improving the flexibility and intelligence of the production line, and at the same time providing a more convenient and personalized service experience for users.

[0014] As an improvement, it also includes a pickup platform and a stacker, the cache shelf includes a transfer platform and a storage shelf, the transfer platform and the storage shelf are located on the same side of the stacker's movement track, and the transfer platform and the storage shelf are arranged side by side, the pickup platform is located in front of the storage shelf, and the stacker is located between the storage shelf and the pickup platform; the transfer slide rail is located above the transfer platform.

[0015] The beneficial effects of this improvement are: the pickup table is located in front of the storage shelf, providing users with a convenient and intuitive pickup area; after visiting the entire production process, users can directly pick up their customized products at the end of the process; the entire process of the goods of offline self-pickup orders from the transmission mechanism to the transfer table, then from the transfer table to the storage shelf, and finally from the storage shelf to the pickup table is visualized. This design reduces obstruction, allowing users to clearly see the flow and processing of goods, enhancing transparency and interactivity;

[0016] The compact layout of the transfer station, storage shelves, stacker and pickup station effectively reduces space occupancy, making the entire smart shelf system more compact and efficient; the cooperation of the stacker and the transfer robot significantly shortens the movement path of the transfer robot, thereby increasing the speed of grabbing the target goods from the conveyor belt. This design not only speeds up the processing speed of offline self-pickup orders, but also avoids the normal transmission of mail order goods affected by the long movement distance of the transfer robot.

[0017] As an improvement, a rotating plate is further provided between the lifting cylinder and the gripping assembly, a rotating cylinder is further provided between the rotating plate and the lifting cylinder, the telescopic end of the lifting cylinder is fixedly connected to the fixed end of the rotating cylinder, the rotating plate is fixedly connected to the rotating end of the rotating cylinder, the gripping assembly comprises a clamping slide rail and a gripping clamp, the clamping slide rail is fixedly mounted on the lower surface of the rotating plate, the clamping slide rail is two parallel rails, respectively used to connect two gripping clamps, and the gripping clamp slider is connected to the clamping slide rail;

[0018] A clamping cylinder is also provided between the two grabbing clamps, the fixed end of the clamping cylinder is fixedly installed on the lower surface of the rotating plate, the telescopic end of the clamping cylinder is fixedly connected to the grabbing clamp, and the telescopic track of the clamping cylinder is parallel to the clamping slide rail; the two grabbing clamps are respectively connected to the clamping cylinders, and the telescopic directions of the two clamping cylinders are set in opposite directions.

[0019] The beneficial effects of this improvement are as follows: the lifting cylinder is extended, so that the gripping clamp assembly moves downward, and the two gripping clamps are respectively located on both sides of the target goods, and the clamping cylinder is contracted, and the gripping clamps move horizontally along the clamping slide rail to contact and clamp the target goods; the lifting cylinder is contracted, and the gripping clamps fix the target goods and move upward, so that the target goods are separated from the conveyor belt; the rotating cylinder drives the gripping assembly to rotate 90 degrees to adjust the horizontal posture of the target goods; finally, the gripping clamp assembly moves along the track of the transfer slide rail to the top of the transfer platform;

[0020] By introducing a rotating plate and a rotating cylinder, the transfer robot has the ability to rotate. This allows the robot to adjust its working direction as needed to meet the movement of goods from the conveyor belt direction to the storage shelf direction; the design of the clamping slide and the gripper allows the two grippers to open and close in parallel, thereby clamping the goods steadily; this clamping method is particularly effective for packaged rectangular product boxes of different models and sizes, and can ensure that the box body will not be deformed or damaged during the clamping process;

[0021] Due to the parallel design of the telescopic direction of the clamping cylinder and the clamping slide rail, the transfer robot can be suitable for product boxes of various specifications and shapes; the same production line produces product boxes of different sizes, weights or shapes, and the transfer robot can ensure a stable clamping effect by adjusting the telescopic amount of the clamping cylinder and the opening and closing degree of the gripper.

[0022] As an improvement, the grabbing clamp includes grabbing fingers, and a single grabbing clamp includes multiple grabbing fingers. The multiple grabbing fingers on a single grabbing clamp are arranged linearly, and the clamping ends of the grabbing fingers are "L"-shaped, respectively contacting the side and bottom surfaces of the goods; open grooves for accommodating the grabbing fingers are provided on both sides of the transfer platform.

[0023] The beneficial effects of this improvement are: since the gripping fingers are designed in an "L" shape and are in contact with the sides and bottom of the goods at the same time, this multi-point contact method greatly increases the stability of clamping; in the process of transferring goods, even if encountering bumps or vibrations, the goods can remain relatively stable and are not easy to fall or tilt; when the transfer robot grabs the goods from the transmission mechanism and transfers them to the transfer table, the gripping fingers can be smoothly embedded in these open grooves, thereby achieving stable placement of the goods; the design of multiple gripping fingers enables the transfer robot to clamp goods of different shapes and sizes; whether it is a small or large product box, as long as its size is within the clamping range of the gripping fingers, it can be stably clamped and transferred; this highly adaptable design improves the flexibility and versatility of the intelligent shelf system.

[0024] As an improvement, the stacker includes a guide rail, a stand and a cargo platform, the guide rail is fixedly installed on the ground between the storage layer shelf and the pickup platform, and the guide rail spans the left and right ends of the transfer platform and the storage layer shelf; the stand is slidably connected to the guide rail, the stand includes a vertically arranged column, the frame of the cargo platform is slidably connected to the column, an adsorption component is installed on the frame of the cargo platform, and the adsorption component is located above the cargo platform;

[0025] The suction component includes a negative pressure suction nozzle for sucking goods and a suction slide for driving the negative pressure suction nozzle to approach or move away from the storage shelf. The slide rail of the suction slide is perpendicular to the front end surface of the storage shelf, and the negative pressure suction nozzle is fixedly mounted on the slider of the suction slide.

[0026] The storage rack includes a back panel for closing the rear end face of the storage rack; a convex edge is provided on one side of the transfer table close to the back panel, and the convex edge of the transfer table is higher than the plane of the transfer table for placing goods.

[0027] The beneficial effects of this improvement are as follows: The vertical rack moves horizontally along the guide rail, so that the vertical rack is located in front of the transfer table, and the loading platform moves vertically along the column to make the loading platform flush with the transfer table; The slider of the adsorption slide moves along the slide rail of the adsorption slide, driving the negative pressure suction nozzle to approach the target goods on the transfer table. The negative pressure suction nozzle contacts one side of the target goods, and the convex edge of the transfer table abuts against the other side of the target goods; The negative pressure suction nozzle generates negative pressure to suck the target goods, and the adsorption slide drives the target goods away from the transfer table. The target goods move to the loading platform with the negative pressure suction nozzle;

[0028] The stacker can operate flexibly in the three-dimensional space between the buffer rack and the picking station, and the negative pressure suction nozzle can extend into the rack to directly contact the goods, so that the stacker occupies less space and significantly improves the utilization rate and storage efficiency of the storage space; The combined use of the negative pressure suction nozzle and the adsorption slide ensures the stability of the goods during transfer and stacking. The negative pressure suction nozzle can firmly adsorb the goods to prevent them from slipping or tipping during movement.

[0029] As an improvement, the tabletop of the loading platform is a rolling loading belt, and the loading belt rotates in the direction close to or away from the storage rack; The adsorption assembly further includes an adsorption cylinder for driving the suction nozzle to approach or away from the loading platform. The fixed end of the adsorption cylinder is fixedly installed on the frame of the loading platform, the telescopic end of the adsorption cylinder faces downward, and the adsorption slide is fixedly connected to the telescopic end of the adsorption cylinder.

[0030] The beneficial effects of this improvement are as follows: When the negative pressure suction nozzle generates negative pressure to suck the target goods, the adsorption slide drives the target goods away from the storage rack, and the target goods move to the loading platform with the negative pressure suction nozzle; The loading belt of the loading platform contacts the bottom of the target goods, and the upper surface of the loading belt rotates in the direction away from the storage rack. The loading belt and the negative pressure suction nozzle drive the target goods to move smoothly to the center of the loading platform together;

[0031] After the target goods move to the center of the loading platform, the negative pressure suction nozzle and the loading platform stop working, and the adsorption cylinder contracts to lift the adsorption slide as a whole. The adsorption assembly is located above the goods on the loading platform and does not block the horizontal movement of the goods; After the transfer process of the target goods from the storage rack to the loading platform is completed, the vertical rack moves horizontally along the guide rail, and the loading platform moves vertically along the column to move the loading platform to the corresponding picking station and align the upper surface of the loading belt with the upper end of the slope of the picking station; Then drive the upper surface of the loading belt to continue rotating in the direction away from the storage rack, and push the target goods from the other side of the loading platform to the picking station;

[0032] Goods can be transferred from both the front and rear directions of the stacker, enhancing the mobility of the goods. There is no obstruction on both sides of the front and rear of the loading platform, making the operating state of the stacker and the position of the goods more intuitively visible. Moreover, the structure of the entire stacker is more compact, saving the operating space of the equipment and making the overall layout of the system more reasonable and beautiful.

[0033] As an improvement, the picking platform includes a slope and a QR code scanning window. The slope of the picking platform slopes downward from the end close to the storage shelf towards the end far from the storage shelf, and a horizontal plane is provided at the end of the slope of the picking platform. The QR code scanning window is arranged on the horizontal plane.

[0034] The beneficial effect of this improvement is that when the user aligns the QR code with the QR code scanning window of the picking platform, the control center locks the placement area of the target goods on the storage shelf and drives the stacker to transfer the target goods from the storage shelf to the corresponding picking platform; when the target goods are pushed to the upper end of the picking platform from the other side of the loading platform; after the target goods leave the loading belt, they slide down along the slope of the picking platform due to gravity and finally stay on the plane at the end of the slope for the user to pick up; the user can stand in front of the picking area and see the whole process of their customized goods being transported from the storage shelf to in front of them.

[0035] As an improvement, a blocking sensor is also provided between the two conveyor belts. The blocking sensor is located below the transfer manipulator, the light of the blocking sensor irradiates vertically upward, and the blocking sensor is located behind the blocking cylinder along the transmission direction.

[0036] The beneficial effect of this improvement is that the blocking sensor ensures that there are goods in this area on the conveyor belt when the transfer manipulator grabs the goods. The blocking sensor is also used to detect whether the target goods reach the grabbing position and issue an operation instruction to the blocking cylinder in a timely manner. While effectively intercepting the target goods, it also avoids the premature extension of the blocking cylinder from affecting the movement of other goods.

[0037] As an improvement, the transmission mechanism includes a rolling wall assembly. The rolling wall assembly includes side frames and roller shafts. The side frames are fixedly installed outside the two sides of the conveyor belts, and a plurality of roller shafts are vertically arranged in the side frames; the plurality of roller shafts are horizontally arranged along the transmission direction of the conveyor belt to form a continuous support surface for supporting the side walls of the goods; there is no rolling wall assembly on both sides of the conveyor belt in the area below the transfer slide rail manipulator.

[0038] The beneficial effects of this improvement are as follows: When the conveyor belt drives the goods to move, both sides of the goods come into contact with the roller shafts. The roller shafts rotate to reduce the frictional force with the goods, lower the resistance of the goods during transmission, and prevent the goods on the conveyor belt from tilting or falling from both sides of the conveyor belt; on both sides of the conveyor belt in the area below the transfer slide rail hand, there is no rolling wall assembly; sufficient space is left for the transfer slide rail hand to pick up goods, avoiding interference from the rolling wall assembly to the operation of the transfer manipulator.

[0049] Embodiment

[0050] Basically as shown in the attachedFigure 1 and the attached Figure 2 As shown, an intelligent shelf for offline orders includes a transmission mechanism 1 for uniformly outputting goods, a buffer shelf 2 for storing self-service goods, a transfer manipulator 3 for transferring self-service goods, a pick-up platform 4, and a stacker 5. This intelligent shelf for offline orders is used for transporting and placing rectangular boxed goods of different models, such as gift boxes.

[0051] The buffer shelf 2 is installed on one side of the transmission track of the transmission mechanism 1. The buffer shelf 2 includes a transfer table 6 and a storage rack 7. The transfer table 6 and the storage rack 7 are located on the same side of the movement track of the stacker 5, and the transfer table 6 and the storage rack 7 are arranged side by side; the transfer manipulator 3 is located above the transmission mechanism 1, and the transfer manipulator 3 is used to grab the goods on the transmission mechanism 1 to the transfer table 6; the pick-up platform 4 is installed in front of the storage rack 7, and the stacker 5 is installed between the storage rack 7 and the pick-up platform 4. The stacker 5 transfers the goods on the storage rack 7 to the pick-up platform 4 for users to pick up offline.

[0052] As attached Figure 3 and the attached Figure 4 As shown, the transmission mechanism 1 includes a transmission platform 8 and a conveyor belt 9. The conveyor belt 9 is arranged above the transmission platform 8. Two sets of driving rollers are respectively arranged at the head and tail ends of the transmission platform 8. The conveyor belt 9 is annularly sleeved on the driving rollers at the head and tail ends. The conveyor belt 9 is tensioned by the driving rollers and driven by the motor connected to the driving rollers. The conveyor belt 9 rotates around the transmission platform 8, and the conveyor belt 9 is respectively located above and below the transmission platform 8, with a spacing between the conveyor belt 9 and the transmission platform 8. Both sides of the goods are respectively placed on two conveyor belts 9.

[0053] A rolling wall assembly 10 is installed on the transmission platform 8. The rolling wall assembly 10 includes a side frame and roller shafts. The side frame is fixedly connected to the transmission platform 8, and the side frame is outside the two sides of the two conveyor belts 9. A plurality of roller shafts are vertically arranged in the side frame; the plurality of roller shafts are horizontally arranged along the transmission direction of the conveyor belt 9 to form a continuous support surface for supporting the side walls of the goods. When the conveyor belt 9 drives the goods to move, both sides of the goods contact the roller shafts, and the roller shafts rotate to reduce the friction with the goods, reduce the resistance of the goods during the transmission process, and prevent the goods on the conveyor belt 9 from tilting or falling from both sides of the conveyor belt 9.

[0054] There is a rectangular opening 11 on the transfer platform 8 below the transfer manipulator 3. Below the rectangular opening 11, there are a blocking cylinder 12 and a blocking sensor 13. The blocking cylinder 12 is located at the center position between the two conveyor belts 9. The blocking cylinder 12 extends vertically upward from within the rectangular opening 11, and the end of the telescopic end extends above the transfer platform 8. The infrared light of the blocking sensor 13 irradiates vertically upward and the light passes through the rectangular opening 11. The blocking sensor 13 is located behind the blocking cylinder 12 along the transfer direction. The blocking sensor 13 is used to detect whether there is a goods above the rectangular opening 11. After the blocking cylinder 12 extends, its telescopic end is higher than the conveyor belt 9. The telescopic end of the blocking cylinder 12 contacts the front end of the goods on the conveyor belt 9, intercepting the goods on the conveyor belt 9 and preventing the goods from moving with the conveyor belt 9. The goods stay at the current position. At this time, there is a relative displacement between the goods and the conveyor belt 9. After the blocking cylinder 12 shortens, its telescopic end is lower than the conveyor belt 9, enabling the goods on the conveyor belt 9 to pass smoothly through the rectangular opening 11 area.

[0055] As shown in the Figure 5 attachment, the transfer manipulator 3 includes a transfer slide rail 14, a sliding flat plate 15, a lifting flat plate 16, a rotating flat plate 17 and a gripper 24 assembly 18. The two ends of the transfer slide rail 14 are respectively located above the rectangular opening 11 of the conveyor belt 9 and above the transfer table 6. A slider is fixedly installed on the upper surface of the sliding flat plate 15. The slider on the sliding flat plate 15 is connected with the transfer slide rail 14 in a matching manner. The transfer slide rail 14 supports the sliding flat plate 15 to slide along the track. The relative displacement between the transfer slide rail 14 and the sliding flat plate 15 is driven by belt transmission. Driving wheels for tensioning the belt are respectively provided at the two ends of the transfer slide rail 14. Among them, the driving wheel close to the transfer platform 8 is connected with a driving motor. A belt clip is fixedly installed on the belt, and this belt clip is fixedly connected with the upper surface of the sliding flat plate 15. The rotation of the driving wheel drives the sliding flat plate 15 to reciprocate along the transfer slide rail 14.

[0056] The lifting flat plate 16 is located below the sliding flat plate 15. There is a lifting cylinder 20 between the lifting flat plate 16 and the sliding flat plate 15. The cylinder seat of the lifting cylinder 20 is fixedly installed on the sliding platform, and the telescopic end of the lifting cylinder 20 is fixedly connected to the lifting platform. The vertical movement of the lifting flat plate 16 is realized by the telescopic movement of the lifting cylinder 20. Slide rods are respectively provided at the four corners of the lifting flat plate 16. The upper ends of the four slide rods penetrate through the four corners of the sliding flat plate 15 and are sleeved with the sliding flat plate 15, enabling the sliding flat plate 15 to move relatively along the axial direction of the slide rods.

[0057] The rotating flat plate 17 is located below the lifting flat plate 16. A rotating cylinder 21 is provided between the rotating flat plate 17 and the lifting flat plate 16. The fixed end of the rotating cylinder 21 is fixedly connected to the lower surface of the lifting flat plate 16, and the rotating end of the rotating cylinder 21 is fixedly connected to the lower surface of the rotating flat plate 17. The rotating cylinder 21 drives the rotating flat plate 17 to rotate 90° relative to the lifting flat plate 16.

[0058] As shown in the attached Figure 6 figure, a gripper 24 assembly 18 is installed on the lower surface of the rotating flat plate 17. The gripper 24 assembly 18 includes clamping slide rails 22, clamping cylinders 23 and grippers 24. The clamping slide rails 22 are two parallel tracks and are fixedly installed on the lower surface of the rotating flat plate 17. Sliders are respectively fixedly installed at both ends of the gripper 24, and the sliders at both ends of the gripper 24 are respectively fitted and installed on the two clamping slide rails 22; There are two grippers 24, which are respectively installed at both ends of the clamping slide rails 22. A clamping cylinder 23 is also provided between the two grippers 24. The fixed end of the clamping cylinder 23 is fixedly installed on the lower surface of the rotating flat plate 17, and the telescopic end of the clamping cylinder 23 is fixedly connected to the gripper 24. The telescopic trajectory of the clamping cylinder 23 is parallel to the clamping slide rail 22. There are two clamping cylinders 23, and their telescopic directions are arranged in opposite directions, and their telescopic ends are respectively connected to different grippers 24. The two grippers 24 are driven to move closer to each other along the tracks of the clamping slide rails 22 by the simultaneous contraction of the two clamping cylinders 23.

[0059] The gripper 24 includes gripping fingers 25. A single gripper 24 includes four gripping fingers 25, and the four gripping fingers 25 are linearly arranged. The clamping ends of the gripping fingers 25 are in an "L" shape and are respectively in contact with the side and bottom surfaces of the goods; When the two grippers 24 move closer to each other for clamping, the gripping fingers 25 on the two grippers 24 clamp and fix the goods on the transfer manipulator 3 from the two sides and the bottom of the goods respectively. There is no rolling wall assembly 10 on the transport platform in the area below the transfer slide rail 14, so that the grippers 24 are located on both sides of the conveyor belt 9 and can clamp and fix the goods from both sides of the goods without obstruction. Open slots 27 for accommodating the gripping fingers 25 are provided on both sides of the transfer table 6.

[0060] The process of transferring the goods from the transport mechanism to the transfer table 6 is as follows:

[0061] Both sides of the bottom of the goods are placed on the conveyor belt 9, and the goods move along with the conveyor belt 9 in the transport direction; When the target goods move to the rectangular opening 11 area, the blocking sensor 13 detects the signal that the target goods have reached above the rectangular opening 11, and the blocking cylinder 12 extends and is located at the front end of the goods to block the target goods from continuing to move with the conveyor belt 9. At this time, the conveyor belt 9 still continues to operate, driving the other goods on the conveyor belt 9 to move.

[0062] Thus, all the goods of all orders are uniformly output by the transport mechanism. The target goods for the offline self-pickup order are blocked and waiting to be grabbed and transferred; The remaining goods of the mailing order are not blocked. During the transfer of the target goods, the remaining goods still move with the conveyor belt 9 together. When they move to the end of the transfer platform 8, they then flow into the background and are processed by the background for mailing.

[0063] The belt-driven gripper 24 assembly 18 is located above the target product, and the lifting cylinder 20 extends, causing the gripper 24 assembly 18 to move downward. The two grippers 24 are located on both sides of the target product, and the clamping cylinder 23 contracts, and the gripping fingers 25 contact and clamp the target product. The lifting cylinder 20 contracts, and the gripper 24 fixes the target product and moves upward, so that the target product is separated from the conveyor belt 9. The rotating cylinder 21 drives the gripper assembly to rotate 90 degrees to adjust the horizontal posture of the target product.

[0064] The belt drives the gripper 24 assembly 18 to move along the track of the transfer slide 14 to the top of the transfer platform 6, and the lifting cylinder 20 extends again, and the gripper 24 clamps the target goods and moves down, and the target goods are stably placed on the transfer platform 6, and the gripper fingers 25 are located in the open slots 27 of the transfer platform 6. The clamping cylinder 23 extends, the gripper 24 opens outward, and the gripper fingers 25 withdraw horizontally from the open slots 27, and the target goods are separated from the transfer robot 3. The transfer robot 3 returns to its original position and waits for the next operation instruction; the target goods are temporarily stored on the transfer platform 6, waiting for the transfer of the stacker 5.

[0065] As attached Figure 7 As shown, the stacker 5 includes a guide rail 28, a stand 29, and a loading platform 30. The guide rail 28 is fixedly installed on the ground between the storage shelf 7 and the pickup platform 4. The guide rail 28 spans the left and right ends of the transfer platform 6 and the storage shelf 7. The stand 29 is slidably installed on the guide rail 28. A pulley is provided at the bottom end of the stand 29 to slide along the guide rail 28. The movement of the stand 29 along the guide rail 28 is driven by a belt. Driving wheels for tightening the belt are provided at both ends of the guide rail 28, and the belt clamp on the belt is fixedly connected to the bottom end of the stand 29.

[0066] A vertical rail surface is fixedly provided above the stand 29 and parallel to the guide rail 28. A clamping wheel group is provided on the left and right sides of the upper end of the stand 29. The clamping wheel group includes two clamping wheels with vertically arranged rotating shafts. The two clamping wheels are respectively located on both sides of the vertical rail surface to clamp the vertical rail surface. When the stand 29 moves along the guide rail 28, the clamping wheels above the stand 29 rub against the vertical rail surface, and the clamping wheels rotate to reduce the friction between the clamping wheels and the vertical rail surface, thereby providing support force to prevent the stand 29 from falling over and ensuring the smooth translation of the stand 29.

The slide rail of the adsorption slide table 32 is perpendicular to the front end face of the storage shelf 7, and the slider of the adsorption slide table 32 is fixedly connected to the negative pressure suction nozzle 33. The slider of the adsorption slide table 32 moves along its slide rail to approach the storage shelf 7 until the negative pressure suction nozzle 33 contacts the side of the goods. The negative pressure suction nozzle 33 generates negative pressure to suck the goods, so that the goods move together with the negative pressure suction nozzle 33.

[0069] The tabletop of the loading platform 30 is a rolling loading belt 34. The loading belt 34 rotates in the direction of approaching or moving away from the storage shelf 7. The inner ends of both sides of the loading belt 34 are tightened by the carrier rollers. One of the carrier rollers is belt-driven by a servo drive motor to drive the forward and reverse rotation of the loading belt 34 to achieve.

[0070] The picking platform 4 includes a slope 35 and a QR code scanning window 36.

[0072] The process of transferring the goods from the transfer platform 6 to the storage shelf 7 is as follows:

[0073] The vertical frame 29 moves horizontally along the guide rail 28, so that the vertical frame 29 is located in front of the transfer table 6, and the loading platform 30 moves vertically along the column, making the loading platform 30 flush with the transfer table 6; the telescopic end of the adsorption cylinder 31 extends, driving the adsorption slide 32 to move downward, and the slider of the adsorption slide 32 moves along the slide rail of the adsorption slide 32, driving the negative pressure suction nozzle 33 to approach the target goods on the transfer table 6. The negative pressure suction nozzle 33 contacts one side of the target goods, and the convex edge 26 of the transfer table 6 abuts against the other side of the target goods; the negative pressure suction nozzle 33 generates negative pressure to suck the target goods, and the adsorption slide 32 then drives the target goods away from the transfer table 6. The target goods move with the negative pressure suction nozzle 33 to the loading platform 30. The loading belt 34 of the loading platform 30 contacts the bottom of the target goods, and the upper surface of the loading belt 34 rotates in a direction away from the storage shelf 7. The loading belt 34 and the negative pressure suction nozzle 33 together drive the target goods to move smoothly to the center of the loading platform 30. After the target goods move to the center of the loading platform 30, the negative pressure suction nozzle 33 and the loading platform 30 stop working, and the adsorption assembly returns to its initial position.

[0074] After the transfer process of the target goods from the transfer table 6 to the loading platform 30 is completed, the vertical frame 29 moves horizontally along the guide rail 28, and the loading platform 30 moves vertically along the column, moving the loading platform 30 to the corresponding area of the storage shelf 7, and aligning the upper surface of the loading belt 34 with the corresponding placement surface of the storage shelf 7; then drive the upper surface of the loading belt 34 to rotate in a direction close to the storage shelf 7, and push the target goods from the loading platform 30 to the storage shelf 7.

[0075] The intelligent shelf realizes the automatic storage of the self-service goods completed in production on the storage shelf 7, and the self-service goods correspond to the storage positions, realizing the intelligent management of the goods.

[0076] The process of the goods being transferred from the storage shelf 7 to the picking table 4 is as follows:

[0077] When the user aligns the two-dimensional code with the two-dimensional code scanning window 36 of the picking table 4, the control center locks the placement area of the target goods on the storage shelf 7 and drives the stacker 5 to transfer the target goods from the storage shelf 7 to the corresponding picking table 4.

[0078] The vertical frame 29 moves horizontally along the guide rail 28, and the loading platform 30 moves vertically along the column, moving the loading platform 30 to the corresponding area of the storage shelf 7, and aligning the upper surface of the loading belt 34 with the corresponding placement surface of the storage shelf 7.

[0079] The telescopic end of the adsorption cylinder 31 extends, driving the adsorption slide 32 to move downward, and the slider of the adsorption slide 32 moves along the slide rail of the adsorption slide 32, driving the negative pressure suction nozzle 33 to approach the target goods on the storage rack 7. The negative pressure suction nozzle 33 contacts one side of the target goods, and the back panel of the storage rack 7 presses against the other side of the target goods; the negative pressure suction nozzle 33 generates negative pressure to suck the target goods, and the adsorption slide 32 then drives the target goods away from the storage rack 7. The target goods move to the loading platform 30 with the negative pressure suction nozzle 33. The loading belt 34 of the loading platform 30 contacts the bottom of the target goods, and the upper surface of the loading belt 34 rotates in the direction away from the storage rack 7. The loading belt 34 and the negative pressure suction nozzle 33 together drive the target goods to move smoothly to the center of the loading platform 30. After the target goods move to the center of the loading platform 30, the negative pressure suction nozzle 33 and the loading platform 30 stop working, and the adsorption assembly returns to its original position.

[0080] After returning to its original position, the adsorption assembly is located above the goods on the loading platform 30 and does not obstruct the horizontal movement of the goods.

[0081] After the transfer process of the target goods from the storage rack 7 to the loading platform 30 is completed, the vertical frame 29 moves horizontally along the guide rail 28, and the loading platform 30 moves vertically along the column, moving the loading platform 30 to the corresponding pick-up platform 4 and aligning the upper surface of the loading belt 34 with the upper end of the slope 35 of the pick-up platform 4; then drive the upper surface of the loading belt 34 to continue rotating in the direction away from the storage rack 7, and push the target goods from the other side of the loading platform 30 to the upper end of the pick-up platform 4. After the target goods are separated from the loading belt 34, they slide down along the slope 35 of the pick-up platform 4 by gravity and finally stay on the plane at the end of the slope 35 for the user to pick up.

[0082] It realizes that the user picks up goods without a person offline on the intelligent shelf. The intelligent shelf will obtain the order information by scanning the QR code, lock the storage area of the target goods, and correspond the target goods to the pick-up platform 4 to realize intelligent picking.
