The servo motor 3 can specifically open a motor slot on the bottom wall of the trough body 2, and then be set in the motor slot. At the same time, a sound-absorbing sponge or other structures with sound-absorbing effect can also be set in the motor slot, so as to absorb the noise generated by the servo motor 3 when it is working to a certain extent.

[0035] In the figure, there are three placement trays 8. The outer placement tray 8 serves as a preliminary placement for documents, and the positions of the other two placement trays 8 are used to distinguish documents of a certain size range. In specific settings, multiple such positions can also be set to perform more detailed sorting of document sizes.

[0036] The setting of the rotating component is used to drive it to rotate through the operation of the servo motor 3 when needed, and when there is no need to rotate, it does not affect the servo motor 3 to provide a power source for the movement of the direction-changing transmission component; the rotating component includes a one-way bearing 5, a turntable 6, and an arc frame 7.

During the specific rotation process, the lower surface of the placement disk 8 is in contact with the lower surface of the trough body 2, which has a certain supporting effect on the placement disk 8.

[0037] The direction-changing transmission component is used to exert a thrust on the document moved to the corresponding position when the rotating component stops rotating, so that the document moves out from the corresponding placement plate 8; the direction-changing transmission component includes a one-way bearing 29, a turntable 210, a column 11, and a support plate 12.

[0038] Reference Figure 1-Figure 8, each of which is slidably mounted with a sliding block 20, and the specific setting method can be as follows: each placement tray 8 is provided with two step slide grooves 19, and each step slide groove 19 is slidably mounted with a step slider, and the upper end of the step slider is fixedly connected to the corresponding sliding block 20; at the same time, a rubber pad 22 is fixedly mounted on one side of the sliding block 20, and the setting of the rubber pad 22 makes the sliding block 20 apply a flexible pushing force when pushing the document to move, and better protects the document when the pushing requirements are met; and a control moving component is installed between the bidirectional screw 13 and the sliding block 20; the control moving component enables the bidirectional screw 13 to apply the required reciprocating motion to the sliding block 20 during the rotation process.

[0039] The control moving component includes a nut 14, a lifting plate 15, a cross block 16, a vertical rod 17, a magnetic block 18, and a magnetic block 21. A magnetic block 21 is fixedly installed on each sliding block 20. The lifting plate 15 is installed on the bidirectional screw 13 through the nut 14. Two cross blocks 16 are fixedly installed on the outer wall of the lifting plate 15. Two magnetic blocks 18 are fixedly installed on one end of the two cross blocks 16 through the vertical rod 17, and the magnetic properties of the corresponding two magnetic blocks 18 on the same side are opposite; the vertical rod 17 can drive the height of the two magnetic blocks 18 to change during the reciprocating movement in the vertical direction, thereby changing the magnetic force relationship of the corresponding magnetic block 21, thereby driving the sliding block 20 to perform the required reciprocating movement in the horizontal direction.

[0040] Reference Figure 1-Figure 8 Two groups of weight sorting components are installed on the trough body 2; the weight sorting components include a circular trough, a material discharge through hole, a sorting plate 42, a short rod 43, an arc-shaped magnetic block 44, and a reset magnetic block 45. Two circular troughs and four material discharge through holes are opened on the sorting seat 1, and the circular trough is connected with the trough body 2 and the corresponding two material discharge through holes. A sorting plate 42 is rotatably installed in each of the two circular troughs; the setting of the weight sorting component allows the document to move into the component under the action of centrifugal force, and the sorting can be automatically realized At the same time, annular grooves are provided on the inner walls on both sides of the two circular grooves, and a plurality of arc-shaped magnetic blocks 44 are fixedly installed on the sorting plate 42 through short rods 43, and reset magnetic blocks 45 matched with the arc-shaped magnetic blocks 44 are symmetrically fixedly installed on the annular grooves. Through the coordinated use of the arc-shaped magnetic blocks 44 and the reset magnetic blocks 45, the sorting plate 42 can be automatically reset after the sorting is completed; a reset spring can also be used to replace the coordinated use of the arc-shaped magnetic blocks 44 and the reset magnetic blocks 45, and the specific selection can be made according to needs.

[0041] Reference Figure 1-Figure 8A support plate 23 is fixedly installed on the outside of the sorting seat 1, and four mounting frames 24 are fixedly installed on the support plate 23. A shaft body 25 is installed between the corresponding two mounting frames 24. A driving motor is fixedly installed on one of the support plates 23, and one end of one of the shaft bodies 25 is fixedly connected to the driving end of the driving motor, and a conveyor belt 26 is sleeved and installed between the two shaft bodies 25; at the same time, a conveyor belt 26 with a plurality of horizontal strips arranged at equal intervals on the surface can be used in the specific setting, so as to better push the document to move to the placement tray 8. This part is the existing technology and will not be elaborated here.

[0042] Reference Figure 1-Figure 8 , an intelligent recognition component is installed between multiple mounting frames 24; the intelligent recognition component includes a support plate 27, a connecting frame 28, a mounting plate 31, a controller 32, and a structure sensor 33. A support plate 27 is fixedly installed between multiple mounting frames 24, a connecting frame 28 is fixedly installed on both sides of the support plate 27, a mounting plate 31 is fixedly installed between the two connecting frames 28, a controller 32 is fixedly installed on the mounting plate 31, and a structure sensor 33 matched with the controller 32 is fixedly installed on the lower surface of the mounting plate 31; the structure sensor 33 is an existing technology, such as Microsoft Kinect and Intel Real Sense, which uses structured light technology to generate a depth image, so that the three-dimensional size of the object can be calculated. At the same time, in conjunction with the use of the controller 32, the calculated three-dimensional size signal can be sent to the controller 32, thereby controlling the position where the placement plate 8 rotates to stop.

[0043] The connecting frame 28 is a damping telescopic setting, and a support plate 29 is fixedly installed at the lower ends of the two connecting frames 28. A wiping sponge 30 that cooperates with the conveyor belt 26 is fixedly installed on the upper surface of the support plate 29; the damping telescopic setting allows the connecting frame 28 to manually control the support plate 29 to move downward when needed, and then the wiping sponge 30 can be dropped for replacement or other required operations. Specifically, the wiping sponge 30 and the support plate 29 can be installed in a detachable fixing manner.

[0044] Reference Figure 1-Figure 8 A plurality of cleaning boxes 36 are fixedly mounted on the support plate 23 through an inclined frame 35, and an air replenishing component is installed between the shaft body 25 and the corresponding cleaning box 36, and a cleaning component cooperating with the intelligent identification component is installed between the corresponding cleaning boxes 36; the setting of the air replenishing component enables the shaft body 25 to continuously replenish air to the cleaning box 36 when rotating, and then deflate it when necessary. During the deflation process, the flow of gas is used to have a blowing and cleaning effect on the documents moved below, which is also convenient for subsequent sorting according to their own weight.

[0045] The air replenishing components include a magnetic block 34, a one-way air inlet pipe 37, a magnetic plate 38, a one-way connecting pipe 39, a square rod, and a sealing slide. The cleaning box 36 is hollow, and a sealing slide is slidably installed in the cleaning box 36. A square rod is fixedly installed on the sealing slide, and the square rod seals and penetrates the corresponding cleaning box 36, and a magnetic plate 38 is fixedly installed on the corresponding square rods. Multiple magnetic blocks 34 are fixedly installed on the two shafts 25, and the outer sides of adjacent magnetic blocks 34 have opposite magnetism. Each cleaning box 36 is fixedly connected to a one-way air inlet pipe 37 and a one-way connecting pipe 39, and the two ends of the one-way connecting pipe 39 are respectively located on both sides of the corresponding sealing sliding, so that the sealing slide can continuously squeeze the gas inhaled on one side to the other side during the movement, so as to facilitate subsequent use.

[0046] The cleaning components include a cleaning main pipe 40, a cleaning branch pipe 41, and an electric valve. A cleaning main pipe 40 is fixedly connected between the two corresponding cleaning boxes 36, and a plurality of cleaning branch pipes 41 are fixedly connected to the cleaning main pipe 40. An electric valve is installed at both ends of the cleaning main pipe 40; the electric valve is also electrically connected to the controller 32, and the controller 32 can be used to intermittently open and close the electric valve, thereby completing the required air blowing cleaning operation.

[0047] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0048] In the present invention, the document is first intermittently placed on the conveyor belt 26, and is transported along with the movement of the conveyor belt 26. During the rotation of the shaft 25, a reciprocating force is generated on the magnetic plate 38. The reciprocating force can generate air pressure in the cleaning box 36 and accumulate continuously. When the document is transported to the bottom of the one-way connecting pipe 39, the corresponding electric valve is opened, so that the cleaning main pipe 40 starts to blow air downward, thereby cleaning the surface of the document.

[0049] The document will continue to move and pass through the structure sensor 33, which measures the size and other information of the document. Then, the controller 32 controls the rotation angle of the servo motor 3 to determine where the placement plate 8 stays. When the document on the conveyor belt 26 is transported to the placement plate 8, the servo motor 3 is used to drive the shaft 4 to rotate. At this time, the shaft 4 drives the placement plate 8 to rotate to the desired position through the one-way bearing 1 5, the turntable 1 6, and the arc frame 7. Then, the shaft 4 is controlled to rotate in the opposite direction. At this time, the one-way bearing 2 9 rotates (the self-locking direction of the one-way bearing 2 9 is opposite to the self-locking direction of the one-way bearing 1 5), and then drives the bidirectional screw 13 to rotate through the column 11 and the support plate 12. The bidirectional screw 13 rotates through the nut 14 and the lifting and lowering screws. The cooperation of the disk 15, the horizontal block 16, and the vertical rod 17 can drive the magnetic block 18 to move back and forth. In this process, the corresponding magnetic block 21 can be subjected to a reciprocating force. When subjected to a repulsive force, the sliding block 20 can move once on the placement disk 8, thereby pushing the document on the placement disk 8. At the same time, due to the different weights of the documents, the positions to which the documents can move when subjected to the thrust are also different, thereby achieving the required sorting according to the weight. The relatively heavy weight will move the sorting disk 42 close to the position of the corresponding placement disk 8, and then make the sorting disk 42 rotate and slide out from the corresponding material discharge hole. On the contrary, the lighter weight will cause the sorting disk 42 to rotate to the other side and slide out from the other material discharge hole.

[0050] 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.
