[0035] Embodiment 1

[0036] See also Figure 1-Figure 7, this embodiment proposes a sorting device for express logistics, which can effectively clean the attachments on the surface of express items and ensure the subsequent scanning and identification effect. The express sorting device has a main conveying structure 1 and a scanning control system 2 for collecting express information. A plurality of branch conveying structures 3 arranged front and back are installed on one side of the main conveying structure 1. A plurality of unloading structures 4 for pushing the express after information scanning to the branch conveying structure 3 are installed on the main conveying structure 1. A cleaning mechanism 5 for cleaning the barcode area on the surface of the express is arranged on the front side of the scanning control system 2. By placing the express items on the main conveying structure 1 in an orderly manner, with the side with the barcode on the express items facing upwards, as the main conveying structure 1 transports the express items from front to back, the scanning control system 2 is used to scan the barcode information on the passing express items, and the branch conveying structure 3 and the unloading structure 4 at the corresponding position are started in the corresponding time period according to the scanned information. After scanning, the express items are transported to the corresponding branch conveying structure 3 via the main conveying structure 1, and the corresponding unloading structure 4 is used to push the express items onto the branch conveying structure 3, and the express items are transported to other locations via the operated branch conveying structure 3. In this way, express items can be transported in different categories.

[0037] When the express delivery is input into the express delivery area information through the scanning control system 2, if the barcode on the surface of the express delivery is blocked by dust or other attachments, it will affect the accuracy of the scanning of the express delivery information, and thus affect the sorting efficiency. Figure 2-Figure 6As shown, in order to improve the accuracy of information scanning during express delivery sorting. The cleaning mechanism 5 equipped in this embodiment includes a lifting frame 501 installed on the main conveying structure 1, and a sensor for detecting the height of the express delivery passing through is installed on the lifting frame 501. The lifting frame 501 is composed of a frame plate and at least two groups of hydraulic cylinders, and the hydraulic cylinders are electrically connected to the sensors. After a group of express delivery passes under the sensor from front to back, the sensor detects the distance between itself and the top surface of the express delivery below, and feeds back the spacing information to the hydraulic cylinder of the lifting frame 501, prompting the hydraulic cylinder to subsequently adjust the height of the frame plate according to the height of the express delivery, so that the cleaning part on the frame plate can fit with the top surface of the express delivery passing through, thereby ensuring the effectiveness of the cleaning mechanism 5 in cleaning the bar code area on the top of the express delivery and the adaptability to express delivery of different heights. The lifting frame 501 is detachably provided with a plate-type soft-bristle brush 502 for brushing the upper surface of the express item when the express item moves from front to back following the main conveying structure 1. Two roller shafts 503 are rotatably provided on the lifting frame 501, which are respectively located at the front and rear sides of the plate-type soft-bristle brush 502. A driving assembly 504 for driving the roller shaft 503 to rotate at the same speed as the main conveying structure 1 is provided on the top of the lifting frame 501. A dust collection assembly 505 for transferring the attachments on the upper surface of the express item and having the suction end extending to the inside of the two roller shafts 503 is provided on one side of the main conveying structure 1. In the initial state, the thrust amount of the hydraulic cylinder in the lifting frame 501 is at the maximum value. After the main conveying structure 1 delivers the express item into the sensor ranging sensing range, the lifting frame 501 descends to a set height to ensure that the bottom surfaces of the roller shaft 503 and the plate-type soft-bristle brush 502 are in close contact with the top surface of the express item. As the main conveying structure 1 continues to operate, the courier is gradually transported to the area below the frame plate. With the help of the plate-type soft brush 502, the top surface of the courier is cleaned to remove the attachments on the barcode on the top of the courier, thereby effectively improving the accuracy of the subsequent scanning control system 2 in scanning the barcode information of the courier. Figure 4 As shown, the front side of the plate-type soft-bristle brush 502 is inclined downward from top to bottom, which can effectively reduce the resistance generated by the plate-type soft-bristle brush 502 to the express item when it passes through the cleaning mechanism 5.

[0038] Within the range of the express plate soft brush 502, the friction force generated by the plate soft brush 502 when cleaning the top surface of the express item is relatively large, which will affect the normal movement of this type of express item. In order to effectively solve this problem, Figure 3-Figure 4As the express item enters the pushing range of the front roller shaft 503, the driving assembly 504 is coordinated to drive the front and rear roller shafts 503 to rotate at the same speed and in the same direction. At the same time, the driving assembly 504 is set to the same speed as the main conveying structure 1 and rotates in the opposite direction to the main conveying structure 1, thereby achieving an effective pushing effect on the express items between the two, ensuring that the express items move normally while cleaning the top bar code area.

[0039] Specifically, the driving assembly 504 includes a transmission structure 1 5041 installed at one end of the two cylindrical structures 5031 away from the hole slot plate 5032, a driving motor 5042 is installed on the top surface of the lifting frame 501, and a transmission structure 2 5043 is installed between the output end of the driving motor 5042 and one end of one of the cylindrical structures 5031. The driving motor 5042 serves as a driving source for driving the cylindrical structures 5031 to rotate, and cooperates with the transmission structure 2 5043 to drive one of the cylindrical structures 5031 to rotate, and then cooperates with the transmission structure 1 5041 to transmit the rotational force to the other cylindrical structure 5031, thereby controlling the two cylindrical structures 5031 to rotate at the same speed and in the same direction.

[0040] Embodiment 2

[0041] Most express parcels are assembled from paper boxes, the top surface of which is usually flat, and the contact area between the roller shaft 503 and the top surface of the express parcel is usually linear. Therefore, when conveying paper box-shaped express parcels, slippage is likely to occur, thereby affecting the pushing effect of the express parcels. In order to further improve the pushing effect of the express parcels, such as Figure 3-Figure 5 The roller shaft 503 includes a cylindrical structure 5031 rotatably mounted on one side of the lifting frame 501, a hole groove plate 5032 rotatably connected to the other side of the lifting frame 501 is mounted on one side of the cylindrical structure 5031, a plurality of strip grooves 5033 are provided on the outer surface of the cylindrical structure 5031, which are used as the suction end of the dust collecting component 505 to suck the attachments on the top surface of the express items along the roller shaft 503, and the outer surface of the cylindrical structure 5031 is provided with the same number of raised rubber strips 5034 as the strip grooves 5033, and the raised rubber strips 5034 are arranged at intervals from the strip grooves 5033, and the outer surface of the raised rubber strips 5034 is provided with an inner groove for forming an uneven surface.

[0042] Specifically, by using the arrangement of the strip groove 5033 and the raised rubber strip 5034, the outer surface of the roller shaft 503 is formed into an uneven shape, thereby increasing the friction between the roller shaft 503 and the box-shaped express item to prevent slipping. And when the height of the lifting frame 501 is adjusted in actual application, the roller shaft 503 and the plate-type soft brush 502 meet the condition that the bottom surface is slightly lower than the height of the top surface of the express item. Under this premise, when the raised rubber strip 5034 in the roller shaft 503 contacts the top surface of the express item, it will be subjected to a certain extrusion force. As the roller shaft 503 continues to rotate, the extrusion force on the raised rubber strip 5034 is transformed into a reaction force on the express item, that is, a driving force, and at the same time, the contact area of ​​the raised rubber strip 5034 with the top surface of the express item is increased, thereby ensuring the effective and stable pushing of the express item.

[0043] More specifically, the width of the strip groove 5033 gradually increases from the inside to the outside of the cylindrical structure 5031, which can enhance the suction capability of the dust collection assembly 505 for objects attached to the top surface of the express item. The inclination angle of the side of the raised rubber strip 5034 is consistent with the inclination angle of the inner wall of the strip groove 5033, thereby ensuring the smoothness of the strip groove 5033 from the outside to the inside.

[0044] Embodiment 3

[0045] In order to further remove the attachments in the barcode area on the top of the express item, such as Figure 3 and Figure 6 As shown, the dust collection assembly 505 includes a suction pipe head 5051 arranged inside the cylindrical structure 5031, a guide pipe 5052 is fixedly connected to the middle of the top surface of the suction pipe head 5051, a dust collector 5053 is on one side of the main conveying structure 1, and the suction end of the dust collector 5053 is connected to a telescopic pipe 5054, and a branch suction pipe 5055 is installed at one end of the telescopic pipe 5054, which passes through the hole groove plate 5032 and is fixedly connected to the two guide pipes 5052. The guide pipe 5052 and one end of the branch suction pipe 5055 are coaxial with the cylindrical structure 5031 and the hole groove plate 5032. The vacuum cleaner 5053 is activated, so that the suction pipe head 5051 sucks air along the lowest strip groove 5033 on the cylindrical structure 5031, so that the attachments on the upper surface of the express item passing through the cleaning mechanism 5 are sucked into the body along the suction pipe head 5051, the guide pipe 5052, the branch suction pipe 5055 and the telescopic pipe 5054, so as to achieve the effect of cleaning the upper surface of the express item. And by arranging the plate-type soft-bristle brush 502 between the two dust suction areas, when the express item passes through the front dust suction area, the loose attachments on the top surface of the express item are first sucked away, and the remaining stubborn attachments are reduced by the friction of the bristles when the express item passes through the plate-type soft-bristle brush 502 area, and then the remaining attachments are sucked away when passing through the rear dust suction area, thereby effectively improving the effectiveness and thoroughness of removing the attachments on the top surface of the express item.

[0046] Embodiment 4

[0047] When the express parcel is pushed by the unloading structure 4 to the branch conveying structure 3 at the corresponding position, the inclined section of the branch conveying structure 3 itself will increase the sliding speed of the express parcel, which may easily cause the express parcel to be hit hard during the sliding process, thus causing damage. Figure 2 and Figure 7 As shown, the branch conveying structure 3 is composed of an inclined downward section close to the main conveying structure 1 and a flat section integrally connected to the inclined downward section. A protective mechanism 6 is installed on the inclined downward section, which is used to slow down the downward speed of the express when it is transferred from the main conveying structure 1 to the branch conveying structure 3. The protective mechanism 6 is electrically connected to the scanning control system 2, the unloading structure 4, and the branch conveying structure 3, which facilitates the coordinated operation of the protective mechanism 6 and the unloading structure 4. The protective mechanism 6 includes positioning rods 601 rotatably plugged on both sides of the inclined downward section, and fixed on the outer surface of the positioning rod 601. A side protection plate 602 is sleeved with an inclination angle consistent with the inclined sliding section, and an anti-collision structure 603 is inserted on the side protection plate 602. The material of the anti-collision structure 603 is any one of rubber, sponge, and airbag. The bottoms of the two positioning rods 601 are fixedly sleeved with a bevel gear 1 604, and a long shaft 605 is rotatably installed at the bottom of the inclined sliding section. Both ends of the long shaft 605 are fixedly sleeved with a bevel gear 2 606 meshing with the bevel gear 1 604, and a stepper motor 607 for driving the long shaft 605 to rotate at a low speed is also installed at the bottom of the inclined sliding section.

[0048] In the initial state of the protection mechanism 6, the two side protection plates 602 are arranged at an angle of 15°-45° with the inclined downward section of the branch conveying structure 3 as the bottom surface, so that the two side protection plates 602 are gradually retracted from top to bottom. On this basis, the unloading structure 4 is coordinated to push the express items from the main conveying structure 1 to the branch conveying structure 3 on one side, and the express items first fall into the range of the two side protection plates 602 to stop the express items from sliding down. At the same time, with the application of the anti-collision structure 603, when the express items slide down and hit the side protection plates 602, the effect of buffering and shock absorption can be achieved, thereby reducing the damage to the express items themselves and the side protection plates 602. Then, the stepper motor 607 is operated to control the long shaft 605 to rotate to a set angle, and the bevel gear 2 606 is used to transmit the rotational force to the bevel gear 1 604, so that the two positioning rods 601 drive the side protection plates 602 and the anti-collision structure 603 to rotate at a low speed to a set angle, so that the two originally retracted side protection plates 602 are gradually unfolded, and then the intercepted express items gradually slide down as the two side protection plates 602 are gradually unfolded, thereby effectively reducing the impact force generated when the express items are transferred from the main transmission structure 1 to the branch transmission structure 3, thereby effectively ensuring the integrity of the express items.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
