in the process of clockwise rotation of the gear 9, the rack 16 is driven to move leftwards under the action of the guide sleeve 15 due to the meshing transmission action of teeth between the gear 9 and the rack 16, and in the process of leftward movement of the rack 16, as shown in fig. 1, 2 and 6, the outer ring of the ratchet wheel I7 is driven to rotate clockwise, so that the inner ring is driven to rotate through the pawl, the second roller 4 is driven to rotate, the conveyor belt 5 is driven to run by rotation of the second roller 4, and the next express parcel is shifted to the right end of the conveyor belt 5, so that the next express parcel can be transported by the clamping mechanism 12;

in the process of anticlockwise rotating of the gear 9, the rack 16 is driven to move rightwards under the action of the guide sleeve 15 due to the meshing transmission action of teeth between the gear 9 and the rack 16, and in the process of rightwards movement of the rack 16, as shown in fig. 1, 2 and 6, the outer ring of the ratchet wheel I7 is driven to rotate anticlockwise, so that the inner ring cannot be driven to rotate through the pawl, the second roller 4 cannot be driven to rotate, the conveyor belt 5 cannot be driven to run, the express package is prevented from being dislocated with the clamping mechanism 12 due to running of the conveyor belt 5 when the clamping mechanism 12 clamps and transports the express package, and the clamping stability and accuracy of the clamping mechanism 12 to the express package are improved;

step two: in the process of clockwise rotation of the gear 9, the rack 16 is driven to move leftwards under the action of the guide sleeve 15 by the meshing transmission action of teeth between the gear 9 and the rack 16, and in the process of leftward movement of the rack 16, as shown in fig. 1, 2, 3 and 7, the outer ring of the ratchet wheel II 32 is driven to rotate clockwise, so that the inner ring cannot be driven to rotate by the pawl, the rotating shaft II 19 cannot be driven to rotate, the chain 23 cannot be driven to rotate by the chain wheel I21, the sorting frame 24 is kept stationary, when the express packages are clamped and transported by the clamping mechanism 12, the express packages can be accurately and reliably placed on the turnover plate 27 of the sorting frame 24, and the phenomenon that the turnover plate 27 and the clamping mechanism 12 are dislocated due to movement of the sorting frame when the clamping mechanism 12 clamps and transports the express packages is avoided;

in the process of anticlockwise rotation of the gear 9, the rack 16 is driven to move rightwards under the action of the guide sleeve 15 by the meshing transmission action of teeth between the gear 9 and the rack 16, in the process of rightward movement of the rack 16, as shown in fig. 1, 2, 3 and 7, the outer ring of the ratchet wheel II 32 is driven to rotate anticlockwise, so that the inner ring is driven to rotate by the pawl, the rotating shaft II 19 is driven to rotate anticlockwise, the rotating shaft II 19 synchronously drives the chain wheel I21 to rotate anticlockwise, so that the chain 23 is driven to operate anticlockwise, the anticlockwise operation of the chain 23 synchronously drives each sorting rack 24 on the chain 23 to operate anticlockwise along with the chain 23, so that each sorting rack 24 passes under each hanging plate 26 one by one, a scanner on the lower surface of each hanging plate 26 is convenient to scan and identify packages passing under the scanner, and express packages are convenient to be sorted one by one, manpower participation is not needed, so that the manpower output is greatly reduced, and the sorting accuracy is improved;

therefore, in the process that the clamping mechanism 12 conveys the express packages from the conveyor belt 5 to the sorting frame 24, the sorting mechanism is kept still, the conveyor belt 5 runs and conveys the next express package, the clamping mechanism 12 puts the express packages down on the sorting frame 24, and in the process that the conveying frame 24 moves to the conveyor belt 5, the conveyor belt 5 is kept still, the sorting mechanism runs and drives the conveying frame to run, so that the conveyor belt 5 and the sorting mechanism run alternately, and the stability and the reliability of the transfer mechanism in the process of conveying are improved;

step three: as shown in fig. 1, 2, 3 and 4, the chains 23 drive the sorting racks 24 to intermittently operate, so that the sorting racks 24 sequentially correspond to the hanging plates 26 at the material guide plates 25 along the chains 23, and thus the scanner under each hanging plate 26 can scan the express parcel information on the turnover plate 27 and transmit the scanned and read information to the controller, the controller determines whether the express parcel information belongs to the target destination corresponding to the material guide plate 25, if so, the corresponding cylinder 28 is controlled to work for a complete stroke, i.e., the piston rod is extended and contracted, when the piston rod is extended upwards and exerts an upward thrust on the corresponding turnover plate 27, so that the turnover plate 27 is turned over to the corresponding material guide plate 25, so that the express parcel on the turnover plate 27 is turned over onto the material guide plate 2, and sorting is completed, no article is on the turnover plate 27 at the leftmost side of fig. 1, and an article is on the turnover plate 27 at the rightmost side, the spring 30 is stretched in the process of overturning the overturning plate 27 to obtain a restoring force, when the piston rod is contracted, no force is applied to the corresponding overturning plate 27, the overturning plate 27 is automatically reset under the action of the restoring force of the spring 30, and the thrust applied to the overturning plate 27 by the piston rod of the first air cylinder 28 can overcome the gravity of the express package and the elastic force of the spring 30, so that the overturning plate 27 can be ensured to be overturned, and the express package is overturned to the material guide plate 2;

if the controller judges that the express parcels do not belong to the target destination corresponding to the material guide plate 25 or the information cannot be read by the scanner (namely, the express parcels on the turnover plate 27 are sorted in front), the corresponding cylinder I28 is not controlled to work, so that the sorting error rate can be greatly reduced, and the working efficiency is improved;

in the time interval when the sorting mechanism does not operate, the sorting frame 24 stays below the corresponding scanner to provide time for scanning, so that the response time of the scanner is adapted, the phenomenon of omission is avoided, and the length of the time interval when the sorting mechanism does not operate is longer than the sum of the response time of the scanner and the time of one complete stroke when the first cylinder 28 works, so that the accuracy of scanning information reading and the sorting stability can be ensured.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
