Description

Technical Field

[0001] The present invention belongs to the technical field of goods sorting, and in particular relates to a goods sorting device based on barcode recognition technology. Background Art

[0002] In modern logistics, warehousing, and production processes, an efficient goods sorting and transmission system is the core of automated operations. Currently, the forms of goods in logistics and warehousing are diverse, including regular boxes, irregular objects, and flexible materials.

[0003] In the prior art, a disc sorter with the publication number CN115870218A mainly includes a conveyor belt frame, a conveyor belt driving shaft, a conveyor belt, a sorting conveyor belt, a rotating disc, a sorting box, and a scanner. The scanner is installed on the conveyor belt through a bracket. The rotating disc rotates, and the conveyor belt releases the sorted items after scanning into the sorting box through the sorting conveyor belt. This disc sorter requires manual placement of the barcode facing up for scanning, which not only has low efficiency but is also prone to errors.

[0004] A fast sorting device based on warehousing logistics with the publication number CN119387162A mainly includes a conveying frame, a return material frame, a tracking mechanism, a reverse recording mechanism, a flipping mechanism, a main conveyor belt, a reverse recording conveyor belt, and a scanning mechanism. During operation, the main conveyor belt drives the goods into the scanning area of the scanning mechanism for barcode scanning. The goods that are not recognized are conveyed to the reverse recording conveyor belt on one side through the reverse recording mechanism, and the goods are flipped on the reverse recording conveyor belt through the flipping mechanism. After flipping, they enter the main conveyor belt again, and the scanning mechanism performs secondary barcode scanning. The flipping mechanism of this device is only applicable to flipping non-fragile goods, and has high requirements for the types and shape structures of goods. Summary of the Invention

[0005] The purpose of the present invention is to provide a goods sorting device based on barcode recognition technology that can flip various sorted goods that fail to be scanned.

[0006] The goods sorting device based on barcode recognition technology includes a rotatable rotating disc. One side of the rotating disc is provided with a conveyor for conveying goods onto it. Above the rotating disc is provided a scanning mechanism for scanning the goods after they are conveyed onto it. The rotating disc has an annular structure, and a plurality of sorting and conveying mechanisms for sorting and conveying are evenly distributed along the circumference thereon. One end of the sorting and conveying mechanism facing the outside can swing towards the inside of the rotating disc. Inside the rotating disc is installed a flipping mechanism for flipping the goods on the sorting and conveying mechanism. The flipping mechanism includes a first rotating frame whose lower end can swing upwards. An elevating conveying component is installed on the first rotating frame. After the first rotating frame swings upwards, the conveying component flips above the sorting and conveying mechanism.

[0007] During use, the conveyor transports the goods to the sorting and conveying mechanism corresponding to the rotating disk. The scanning mechanism scans the barcodes of the goods transported to the sorting and conveying mechanism. When the barcode is at the bottom of the goods and the scanning fails, since the barcode is at the bottom of the goods, the goods need to be flipped. The lower end of the first rotating frame swings upward, the conveying component flips above the sorting and conveying mechanism, the conveying component moves down to the top of the goods, the sorting and conveying mechanism swings inward, and at the same time the first rotating frame swings downward, the goods are flipped onto the conveying component. The conveying component starts to convey and transports the flipped goods to the sorting and conveying mechanism. The barcode located at the bottom of the goods is at the top of the goods after flipping. The scanning mechanism scans the goods again. When the sorting personnel sort the goods, they only need to place the goods at the input end of the conveyor, without considering the orientation of the barcodes on the goods, saving sorting time and improving sorting efficiency.

[0008] Further, the cross-section of the first rotating frame is in an "L" shape. The conveying component is installed on the horizontal part of the first rotating frame. The horizontal part of the first rotating frame can swing upward. After swinging upward, the conveying component flips above the sorting and conveying mechanism.

[0009] The first rotating frame with an "L" shape facilitates the conveying component to flip above the sorting and conveying mechanism after the horizontal part swings upward, and can also prevent the goods from falling out from below during the flipping process. Both regular and irregular goods can be flipped, with a wide range of applications.

[0010] Further, the sorting and conveying mechanism includes a conveyor belt that conveys in the inner and outer directions of the rotating disk. The conveyor belt is installed on the rotating disk through a mounting frame. The mounting frame includes a fixed frame fixed on the rotating disk. A second rotating frame that can swing toward the inner side of the rotating disk is hinged on the fixed frame. One end of the second rotating frame facing the inner side of the rotating disk is hinged to the fixed frame. A second gear is fixed on the second rotating frame at the hinged end. The conveyor belt is fixed on the second rotating frame; The flipping mechanism further includes a mounting frame. A second power output component for driving the second gear to rotate is installed on the mounting frame. The upper end of the first rotating frame is hinged on the mounting frame. A first gear is fixed on the first rotating frame at this hinged end. A third power output component for driving the first gear to rotate is installed on the mounting frame.

[0011] When the goods need to be flipped, the third power output component drives the first gear to rotate, driving the first rotating frame to swing upward. The horizontal part of the first rotating frame swings above the conveyor belt. The conveying component moves down to the top of the goods. The second power output component drives the second gear to rotate, and the outer end of the second rotating frame swings inward, driving the conveyor belt to swing inward. At the same time, the third power output component drives the first gear to rotate in the reverse direction, and the first rotating frame swings downward. The goods are flipped onto the conveying component, saving time and effort.

[0012] Further, a linear movement mechanism is provided at the bottom of the mounting frame. The mounting frame is fixed on the moving platform of the linear movement mechanism, and the bottom of the linear movement mechanism is connected to an inner casing, and the inner casing is rotatably mounted in a rotating disk.

[0013] The inner casing rotates to drive the flipping mechanism to rotate inside the rotating disk. When the scanning mechanism fails to scan the code, the rotating disk rotates first, and the goods with failed code scanning rotate with the rotating disk on the conveyor belt. When the scanning mechanism scans the goods on the next conveyor belt, the flipping mechanism flips the goods with failed code scanning and rotates and stops synchronously with the rotating disk. The goods can be flipped during the normal operation of the rotating disk. After the goods are successfully flipped, under the drive of the rotation of the inner casing and the linear movement mechanism, the flipping mechanism is moved to the sorting conveyor mechanism below the scanning mechanism, the conveying assembly is lifted, and the flipped goods are conveyed back onto the conveyor belt. The scanning mechanism scans the flipped goods, thereby not affecting the normal sorting work of the rotating disk and improving work efficiency.

[0014] Further, fixing plates are respectively provided on both sides parallel to the conveying direction of the conveyor belt. A mounting frame is fixed between the two fixing plates inside the conveyor belt. A support assembly and a tensioning roller capable of moving up and down are respectively mounted on the mounting frame. A guiding member cooperating with the support assembly is fixed on the conveyor belt corresponding to the support assembly, and is used to drive the conveying area of the conveyor belt to move up and down with the support assembly. The lower end of the tensioning roller contacts the inner bottom of the conveyor belt. When the support assembly moves down, the tensioning roller moves up, driving the middle conveying area of the conveyor belt to be recessed inward.

[0015] The guiding member can be used for guiding during the conveying of the conveyor belt and at the same time drive the conveyor belt to move up and down with the support assembly. When the conveyor belt is conveying normally, the upper goods conveying area is horizontal. The support assembly plays a role in guiding and supporting. The tensioning roller moves down to tension the conveyor belt to ensure the normal operation of the conveyor belt. The goods barcode is located at the bottom. When the scanning mechanism fails to scan the code, the support assembly moves down, driving the middle conveying area on the upper side of the conveyor belt to move down. The tensioning roller moves up, and the support assembly drives the lower conveyor belt to move up to be horizontal. The middle conveying area of the upper conveyor belt is recessed inward and is in a tensioned state at the same time. The conveyor belt is started. When the goods conveyed from the conveyor are in a columnar structure, the goods rotate on their own in the recessed conveying area of the conveyor belt, exposing their bottom barcode and being scanned by the scanning mechanism, reducing the flipping of the goods by the flipping mechanism and improving work efficiency.

[0016] Further, an adjusting rod capable of rotating about its own axis is installed on the mounting frame. On both sides of the adjusting rod, a first adjusting plate and a second adjusting plate capable of moving up and down are respectively provided on the mounting frame. The supporting assembly is installed on the first adjusting plate, and the tensioning roller is installed on the second adjusting plate. On the sides of the first adjusting plate and the second adjusting plate facing the adjusting rod, racks are fixed respectively. On the adjusting rod, gears meshing with the racks are installed respectively. The power input end of the adjusting rod is connected with a first power output assembly for driving its rotation.

[0017] The first power output assembly drives the adjusting rod to rotate, driving the supporting assembly to move downward and the tensioning roller to move upward; when the adjusting rod rotates in the reverse direction, it drives the supporting assembly to move upward and the tensioning roller to move downward, which is convenient for adjustment.

[0018] Further, the first adjusting plate is perpendicular to the conveying direction of the conveyor belt. The supporting assembly is installed at the middle position on the top of the first adjusting plate. On the first adjusting plates on both sides of the supporting assembly, auxiliary supporting assemblies are respectively installed. Both the supporting assembly and the auxiliary supporting assembly include rotating shafts rotatably installed on the first adjusting plate. On the rotating shafts, rollers cooperating with the guiding members are fixed respectively. The cross-section of the guiding member is arranged in an "L" - shaped structure, and the end of the roller is located on the upper side of the horizontal part of the guiding member.

[0019] The end of the roller is located on the upper side of the horizontal part of the guiding member, which neither hinders the conveying of the conveyor belt. At the same time, moving the roller up and down can drive the conveying area of the conveyor belt to sink downward or level upward; the supporting assembly and the auxiliary supporting assembly make the conveyor belt more stable during the up - and - down movement and the conveying process.

[0020] Further, the scanning mechanism includes a fixing frame in an inverted "L" - shaped structure. Its vertical part is fixed on the side wall of the conveyor, and its horizontal part is located above the rotating disc. And a barcode scanner and a protection plate capable of moving along the inner and outer sides of the rotating disc are installed at the bottom of the horizontal part.

[0021] When the conveyor conveys goods to the conveyor belt on the rotating disc, the protection plate is located inside the rotating disc to prevent the goods from being thrown into the inner area of the rotating disc. When the flipping mechanism conveys goods to the conveyor belt under the barcode scanner, the protection plate is located outside the rotating disc, which neither hinders the conveyance of the goods nor can prevent the goods from being thrown out.

[0022] Further, the conveying assembly is a belt - type conveyor.

[0023] The belt - type conveyor can not only convey the flipped goods back to the conveyor belt, but also when it descends to the top of the goods above the conveyor belt, the belt makes flexible contact with the goods, making the goods more stable during flipping.

[0024] Further, the linear moving mechanism is a linear motor installed on the inner machine shell.

[0025] Linear motors accelerate quickly and are convenient for automatic control, facilitating the rapid flipping of goods during the normal sorting process of the rotating disk and improving work efficiency.

[0026] Compared with the prior art, the present invention has the following beneficial effects: When the barcode is at the bottom of the goods and the barcode scanning fails, the goods can be flipped. After flipping, the barcode originally at the bottom of the goods is at the top. When sorting personnel sort the goods, they do not need to consider the orientation of the barcode on the goods, saving sorting time and improving sorting efficiency. The goods of various types can be flipped, including regular and irregular goods, and the applicable range is wide. BRIEF DESCRIPTION OF THE DRAWINGS

An installation bracket 1.8 is provided inside the two fixing plates 1.1, and the installation bracket 1.8 is fixedly connected to the fixing plates 1.1. As Figure 3 and Figure 4 shown, the mounting bracket 1.8 has an inverted "convex" shape structure. Through holes are opened in its upper half and the adjusting rod 1.7 is independently inserted. The two ends of the adjusting rod 1.7 face the two fixing plates 1.1 respectively. As Figure 3 and Figure 5As shown, a notch is opened at the vertical center of the mounting bracket 1.8. The notch communicates with the through hole for passing through the adjusting rod 1.7, and gears are sleeved on the adjusting rod 1.7 at the notch and at both ends of the adjusting rod 1.7. As Figure 3 shown, a first power output component 1.6 is installed at the bottom of the mounting bracket 1.8. The motor of the first power output component 1.6 is installed at the bottom of the mounting bracket 1.8, and the driving gear meshes with the gear at the center notch of the mounting bracket 1.8, so as to drive the adjusting rod 1.7 to rotate by the first power output component 1.6. Specifically, the motor of the first power output component 1.6 rotates to drive the driving gear to rotate, and then drives the adjusting rod 1.7 to rotate.

[0034] As Figure 4 shown, on one side of the mounting bracket 1.8, a first adjusting plate 1.9 with a square structure is installed through a slide rail. The track of the slide rail is vertically fixed on the mounting bracket 1.8, and the slider of the slide rail is fixed to the first adjusting plate 1.9. At the middle and both ends of the top of the first adjusting plate 1.9, there are semi-circular mounting seats. Mounting holes are horizontally opened on the semi-circular mounting seats. There are two mounting seats at the middle position, and a support component 1.5 is installed thereon. The support component 1.5 consists of a roller sleeved at both ends of a rotating shaft, and the rotating shaft rotates through the two mounting holes of the mounting seat at the middle position of the first adjusting plate 1.9. Auxiliary support components 1.10 are installed on the mounting seats at both ends of the top of the first adjusting plate 1.9. The auxiliary support component 1.10 consists of a rotating shaft and a roller sleeved on one side of the rotating shaft. The rotating shaft rotates through the mounting hole of the mounting seat at both ends of the top of the first adjusting plate 1.9, and the rollers of the auxiliary support component 1.10 are respectively located outside the mounting bracket 1.8. On the first adjusting plate 1.9, racks are vertically installed in meshing fit with the gears at both ends of the adjusting rod 1.7, so as to drive the first adjusting plate 1.9 to move up and down by the adjusting rod 1.7.

[0035] On the other side of the mounting bracket 1.8, a second adjusting plate 1.11 is installed through a slide rail. The track of the slide rail is vertically installed on the adjusting rod 1.7, and the slider of the slide rail is fixed to the second adjusting plate 1.11. The second adjusting plate 1.11 is of a rectangular plate structure, and fixing rings are installed on its left and right sides, and a tension roller 1.3 is installed between the two fixing rings. On the side of the second adjusting plate 1.11 facing the adjusting rod 1.7, a rack is vertically fixed, and the rack meshes with the gears at both ends of the adjusting rod 1.7, so as to drive the second adjusting plate 1.11 to move up and down by the adjusting rod 1.7.

[0036] As Figure 5 shown in the direction, rotating rollers 1.4 are installed on both the left and right sides inside the two fixing plates 1.1. The rotating shafts thereof are connected to the fixing plates 1.1 through bearing seats, or through holes can be opened on the fixing plates 1.1, and the rotating rollers 1.4 are installed through bearings at the through holes. As Figure 4 and Figure 5As shown, one side of the mounting bracket 1.8 is connected to the mounting plate 1.12 of the rectangular block through a "7"-shaped connecting piece. A driving assembly 1.13 is mounted on the mounting plate 1.12. The assembly consists of a motor, a pulley and a belt. The pulleys are respectively sleeved on the rotating shafts of the rotating rollers 1.4 and the motor shaft of the driving assembly 1.13, and the two are connected by a belt, so as to realize the driving assembly 1.13 driving the rotating rollers 1.4 to rotate.

[0037] As Figure 1 , Figure 3 and Figure 4 shown, a conveyor belt 1.2 is sleeved on the two rotating rollers 1.4. As Figure 3 shown, guide members are fixed on both side edges and the middle part of the conveyor belt 1.2. The guide members are provided with limiting grooves having an "L"-shaped cross section, and their horizontal parts all face inwards. The outer ends of the rollers of the two auxiliary support assemblies 1.10 are both located in the limiting grooves, and the two ends of the rollers of the support assembly 1.5 are located in the middle limiting groove of the conveyor belt 1.2, which can be used for guiding the conveyor belt 1.2 during transportation, and at the same time the conveyor belt 1.2 can move up and down with the support assembly 1.5.

[0038] As Figure 1 and Figure 7 shown, an inner housing 3 is assembled inside the outer housing 2. The main body of the inner housing 3 is disk-shaped, and a horizontal groove is provided at the horizontal center. A linear movement mechanism 5 is embedded in the groove. The linear movement mechanism 5 is a prior art and can be selected in the form of a screw drive or a linear motor. The mounting bracket 4.4 is fixed on the moving platform of the linear movement mechanism 5; when a screw drive is selected, its base is fixedly installed with the inner housing 3; when a linear motor is selected, its slide rail is fixedly installed with the inner housing 3. A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and unfolded into a plane. A linear motor is also called a linear motor, a linear motor, a linear motor, a push rod motor. The most commonly used types of linear motors are flat type, U-groove type and tubular type. A linear motor has a guided slide rail and a slider, and the slider is a moving platform for fixedly installing the mounting bracket 4.4.

[0039] As Figure 6 shown, a fourth gear 13 is assembled between the bottom of the outer wall of the inner housing 3 and the bottom of the inner wall of the outer housing 2. The fourth gear 13 is fixedly connected to the bottom of the inner wall of the outer housing 2. A cylindrical convex block is fixed at the center of the bottom outer wall of the inner housing 3, and the convex block is rotatably installed in the inner hole of the fourth gear 13. As Figure 7 shown, a fifth power output assembly 14 is assembled on the side wall of the inner housing 3, and its driving gear meshes with the fourth gear 13, so as to realize the fifth power output assembly 14 driving the inner housing 3 to rotate around the center of the fourth gear 13.

[0040] As Figure 6 andFigure 7 As shown in the figure, a turnover mechanism 4 is installed on the slider of the linear movement mechanism 5. The mechanism includes a second power output component 4.1, a first gear 4.2, a third power output component 4.3, a mounting bracket 4.4, a first rotating bracket 4.5, a conveying component 4.6, a lifting component 4.7, and a hinge block 4.8. Among them, the cross-section of the mounting bracket 4.4 is in the shape of an "L", with baffles on both sides. The third power output component 4.3 is installed in the center of the top of the mounting bracket 4.4. The motor of the third power output component 4.3 is fixed on the top of the third power output component 4.3, and the driving gear is located at the center position of the mounting bracket 4.4 in the front-back direction. Two "L"-shaped hinge blocks 4.8 are installed on the top of the mounting bracket 4.4 at intervals and symmetrically. A pivot is used to hinge the two hinge blocks 4.8 to the "L"-shaped first rotating bracket 4.5. A groove is opened at the center position of the top of the first rotating bracket 4.5 in the front-back direction, and the first gear 4.2 is installed. The first gear 4.2 is fixed to the first rotating bracket 4.5 and meshes with the driving gear of the third power output component 4.3. Thus, the third power output component 4.3 can drive the first rotating bracket 4.5 to rotate around the first gear 4.2 as the center.

[0041] As Figure 6 shown, the lifting component 4.7 is installed on the top of the horizontal part of the first rotating bracket 4.5. The base of the lifting component 4.7 is fixedly connected to the horizontal part of the first rotating bracket 4.5, and the conveying component 4.6 is fixedly installed on the lifting platform. The conveying component 4.6 is a belt conveyor, that is, a belt conveyor in the prior art, also called a belt conveyor, which is fixed on the lifting platform of the lifting component 4.7. The top is the conveying area, and a pressure sensor is installed on the belt.

[0042] As Figure 2 and Figure 7 shown, two second power output components 4.1 are symmetrically assembled on the front and back sides of the top of the mounting bracket 4.4, and the axes of their driving gears are at the same horizontal height as the axis of the second gear 9.1. When the linear movement mechanism 5 drives the mounting bracket 4.4 to move leftward until the centers of the first gear 4.2 and the second gear 9.1 are aligned, the driving gears of the second power output components 4.1 respectively mesh with the second gear 9.1, and then the second rotating bracket 9.2 can be driven to rotate around the center of the second gear 9.1.

[0043] As Figure 1 shown, a conveyor 6 is installed on the right side of the outer casing 2, and a scanning mechanism 7 is connected to its left end. The scanning mechanism 7 includes an inverted "L"-shaped fixing bracket 7.1, a rotating table 7.2, and a barcode scanner 7.3. The fixing bracket 7.1 is fixed on the conveyor 6, the rotating table 7.2 is installed on the horizontal part of the top of the fixing bracket 7.1, which is composed of a motor and a turntable. The barcode scanner 7.3 is fixed on the turntable, and the rotating table 7.2 can drive the barcode scanner 7.3 to achieve 360-degree rotation. As Figure 1 and Figure 2As shown, a protective plate 8 is vertically installed below the fixing frame 7.1 by a linear motor. The linear motor is a prior art. Slide rails are installed on the front and rear sides of the fixing frame 7.1. The slider cooperates with the slide rails and its side wall is connected to the protective plate 8. The linear motor can drive the protective plate 8 to slide left and right.

[0044] The usage instructions of the above technical solution are as follows: Before use, as Figure 2 shown, the inner casing 3 rotates and adjusts the flipping mechanism 4 to wait at the position to be flipped. For example, it can be adjacent to a sorting and conveying mechanism 1 corresponding to the scanning mechanism 7. When encountering goods to be flipped, the rotating disk 10 continues to rotate. When the scanning mechanism 7 scans the next goods, the flipping mechanism 4 flips the goods to be flipped on the rotating sorting and conveying mechanism 1, and sorting boxes or sorting conveyor belts are placed at each sorting and conveying mechanism 1 outside the outer casing 2.

[0045] When the goods are scanned, as Figure 1 shown, the goods are conveyed by the conveyor 6 to the sorting and conveying mechanism 1 below the scanning mechanism 7. At this time, the barcode scanner 7.3 of the scanning mechanism 7 identifies the barcode information, and the protective plate 8 can effectively prevent the goods from rushing out of the scanning area due to inertia. As Figures 3 to 5 shown, start the first power output component 1.6, the adjusting rod 1.7 rotates, drives the first adjusting plate 1.9 to move down, and the second adjusting plate 1.11 moves up. With the coordinated action of the support component 1.5, the auxiliary support component 1.10 and the tensioning roller 1.3, the top conveying area of the conveyor belt 1.2 sinks downward and is tensioned. If encountering cylindrical goods, start the driving component 1.13, the rotating roller 1.4 drives the conveyor belt 1.2 to operate, prompting the cylindrical goods to rotate on their own in the sunken area of the conveyor belt 1.2 to ensure that the surface information is scanned comprehensively. Then start the first power output component 1.6 again. At this time, the first adjusting plate 1.9 moves up, the second adjusting plate 1.11 moves down, the conveying area of the goods on the upper conveyor belt 1.2 is horizontal, the support component 1.5 plays a guiding and supporting role, and the tensioning roller 1.3 moves down to tension the conveyor belt 1.2 to ensure the normal operation of the conveyor belt 1.2.

[0046] In the goods sorting link, after the scanning is completed, as Figure 5 shown, start the fourth power output component 12, and the fourth power output component 12 drives the rotating disk 10 to rotate, moving the rear sorting and conveying mechanism 1 below the scanning mechanism 7 to prepare for receiving the next goods to be scanned. After the scanned goods are conveyed to the designated area by the rotating disk 10, the conveyor belt 1.2 is tensioned downward by the tensioning roller 1.3, and its top is in a horizontal state. Then start the driving component 1.13, the conveyor belt 1.2 operates, and the goods smoothly fall into the sorting box or the sorting conveyor belt to complete the sorting process.

[0047] When the goods barcode is located at the bottom of the goods and the scanning mechanism 7 fails to scan the code, the goods first rotate with the rotating disk 10. When the next conveyor belt 1.2 is located below the scanning mechanism 7, as Figure 8 shown, start the linear movement mechanism 5, translate the flipping mechanism 4 to the conveyor belt 1.2 corresponding to the goods with scanning failure, and align the centers of the first gear 4.2 and the second gear 9.1. During the movement, simultaneously start the third power output component 4.3, drive the first rotating frame 4.5 to rotate with the axis of the first gear 4.2 as the rotation axis, and swing 180 degrees. Then start the lifting component 4.7, move the conveying component 4.6 to the top of the goods, clamp the goods between the conveying component 4.6 and the conveyor belt 1.2, and set the downward pressure of the conveying component 4.6 according to the pressure sensor on the conveying component 4.6 to facilitate clamping of the goods. Subsequently, start the second power output component 4.1 and the third power output component 4.3. The second power output component 4.1 drives the second rotating frame 9.2 to flip the sorting and conveying mechanism 1, and the third power output component 4.3 drives the first rotating frame 4.5 to drive the conveying component 4.6 to flip 180 degrees synchronously, realizing complete flipping of the goods. After the sorting and conveying mechanism 1 returns to its original position with the help of the second power output component 4.1, after the inner casing 3 rotates, the linear movement mechanism 5 drives the flipping mechanism 4 to move to the sorting and conveying mechanism 1 corresponding to below the scanning mechanism 7 and wait. At the same time, the lifting component 4.7 is started, and the position of the goods is flexibly adjusted according to the height of the sorting and conveying mechanism 1 to ensure that the goods are smoothly transferred to the sorting and conveying mechanism 1 corresponding to below the scanning mechanism 7. Re-enter the scanning area of the scanning mechanism 7 to complete the scanning operation. When the conveying component 4.6 conveys the flipped goods to the sorting and conveying mechanism 1 below the scanning mechanism 7, the conveyor 6 pauses the transmission on this side and waits for the next cycle, and moves the protection plate 8 to the right side of the scanning mechanism 7 through the linear motor to avoid interference and prevent the goods from being thrown out. During the operation of the device, starting the fifth power output component 14 can realize the synchronous rotation of the inner casing 3 and the rotating disk 10, so that the goods flipping operation of the flipping mechanism 4 and the sorting and conveying mechanism 1 is completed synchronously during the rotation of the rotating disk 10, avoiding the time waste of the scanning mechanism 7 waiting for the flipping process and improving the overall operation efficiency.

[0048] The flipping mechanism 4 and the sorting and conveying mechanism 1 work together, clamp and then flip; the flexible flipping method ensures the stability of the goods during the flipping process. Effectively avoids knocking and damaging the goods. It can also flip irregular and thinner goods, improving the adaptability and versatility of the equipment.

[0049] In the sorting and conveying mechanism 1, the conveyor belt 1.2 is sunken downward to form a groove. When encountering cylindrical barrel-shaped goods, the drive assembly 1.13 is activated, and the rotating roller 1.4 drives the conveyor belt 1.2 to operate, prompting the cylindrical barrel-shaped goods to rotate within the depression of the conveyor belt 1.2 to ensure that the surface information thereof is comprehensively scanned. The cylindrical barrel-shaped goods can be directly scanned without being flipped, which improves the scanning efficiency, reduces unnecessary operation steps, and enhances the overall operating efficiency of the equipment.
