[0002] Logistics conveying devices play a vital role in supply chain management. Through transportation optimization, logistics can effectively shorten transportation time, reduce the amount of inventory, and achieve the overall goal of speeding up logistics transportation.

[0003] The logistics conveying device makes it very convenient to transport goods, but when there are too many goods, manual screening and sorting are required. The four types of goods, large cartons, large bags, small cartons and small bags, are classified. The large bags are hemp bags, which generally contain luggage mailed by students, such as bedding and pillows. Large cartons generally contain electronics, daily products, etc. Small cartons generally contain jewelry or smaller items. Small bags generally contain clothes such as short-sleeved shirts and pants. Large cartons and large bags are mixed and placed in designated locations, which require manual sorting. The process is more cumbersome and the sorting efficiency is low. When sorting small bags, the small bags are easy to fold together.

[0030] When screening and sorting the four types of goods, namely, large cartons, large bags, small cartons and small bags, the first drive motor 104 is started manually, the output shaft of the first drive motor 104 rotates counterclockwise to drive the first transmission roller 105 to rotate counterclockwise, the first transmission roller 105 can drive the second transmission roller 106 and the third transmission roller 107 to rotate counterclockwise through the pulley and belt of the transmission assembly, the second transmission roller 106 rotates counterclockwise through the first bevel gear to drive the second bevel gear to rotate counterclockwise, the rotation of the second bevel gear drives the first rotating rod 109 to rotate counterclockwise, the first rotating rod 109 drives the second conveyor belt 110 and the second rotating rod 111 to rotate counterclockwise through friction, and then the four types of goods are intermittently placed on the first conveyor belt 108 manually. It is worth noting It is noted that the large bag needs to be placed on the first conveyor belt 108 in a flat state. At this time, the goods move with the first conveyor belt 108. When the goods move and contact one side of the two guide plates 6, the two guide plates 6 move away from each other and squeeze the two fifth springs. The force released by the fifth springs makes the two guide plates 6 close to the two sides of the goods, ensuring that the goods move in the center of the first conveyor belt 108. When the goods leave one side of the two guide plates 6, the two fifth springs are released and drive the two guide plates 6 to reset, and the goods continue to move. When one side of the goods contacts the second conveyor belt 110, it means that the goods are large cartons or large bags. On the contrary, if the goods do not contact the second conveyor belt 110, they are small cartons or small bags, and they will continue to move forward. The large cartons or large bags are in contact with the second conveyor belt 110, and the force of the counterclockwise rotation of the second conveyor belt 110 and the forward movement of the first conveyor belt 108 causes the large cartons or large bags to tilt and rotate, and fit the second conveyor belt 110 and one side of the fourth side plate 203 to move toward the second support plate 201. When the goods reach the top of the second support plate 201 and are away from the second conveyor belt 110, a number of electric rollers rotate to drive the goods to fit one side of the fourth side plate 203 and continue to move. Initially, the first hinge rod 204 and the second hinge rod 205 tilt toward the second rotating rod 111. When the goods are large cartons, one side of the large carton contacts and slides with the contact ball surface of the first hinge rod 204. The fourth hinge rod 208 controls the sealing box 207 to pull the third hinge rod 206, so that the third hinge rod 206 drives the second hinge rod 205 to rotate synchronously. The torsion spring is deformed by force. At this time, the first spring in the sealing box 207 is not compressed. At this time, the first hinge rod 204 and the second hinge rod 205 are in a parallel state. As the large carton moves, the contact ball surface of the second hinge rod 205 contacts and slides with one side of the large carton. The surface of the large carton is flat, so the large carton does not squeeze the second hinge rod 205 when it contacts the second hinge rod 205. The large carton moves along the rotation direction of the electric roller until the large carton is separated from one side of the second support plate 201. The large carton is manually collected and processed. When the second hinge rod 205 is separated from the large carton, the torsion spring is reset and drives the second hinge rod 205 to rotate counterclockwise and reset. The second hinge rod 205 controls the movement of the sealing box 207 through the third hinge rod 206. When the sealing box 207 moves, the fourth hinge rod 208 drives the first hinge rod 204 to rotate counterclockwise and reset. When the cargo is a large bag, the large bag moves in the same manner as the large cardboard box. Since the large bag contains bedding and pillows, the surface of the large bag is uneven. Therefore, the large bag will not slide on the contact ball surface of the second hinge rod 205 like the large cardboard box, but will push the contact ball of the second hinge rod 205 through the protrusion of the large bag, causing the second hinge rod 205 to rotate clockwise, and squeeze the first spring in the sealing box 207 through the third hinge rod 206. The torsion spring is further deformed by force. At this time, the hydraulic oil in the sealing box 207 is squeezed, and the hydraulic oil flows into the sealing tube 210 through the first transmission pipe 209 to push the push rod 211 to move. The push rod 211 moves and drives the gear 213 to rotate through the rack 212. The rotation of the gear 213 brings The movable shaft 214, the first clamping block 216 and the conveying disc 3 rotate synchronously. When the first clamping block 216 rotates, the inclined surface contacts and squeezes the inclined surface of the second clamping block 217. At this time, the second spring is compressed. When the first clamping block 216 passes the second clamping block 217, the first clamping block 216 and the second clamping block 217 are disengaged to release the second spring and drive the second clamping block 217 to reset. Then, the plane of the second clamping block 217 is clamped with the plane of the first clamping block 216 to limit the rotating shaft 214, which can prevent the conveying disc 3 from resetting during the conveying of the large bag. At the same time, after the conveying disc 3 rotates, it will change the conveying direction of the large bag to align it with the third support plate 402, and then the large bag will be conveyed to several electric rollers on the top of the third support plate 402. The large bag continues to move. When When the large bag moves to the inclined surface of the moving block 403, the moving block 403 moves downward under the action of the gravity of the large bag and squeezes the third spring. Then the large bag slides down into the first collecting box 405. The third spring is released to drive the moving block 403 to reset. At the same time, the moving block 403 moves downward and drives the clamping plate 215 to move downward through the connecting rod 404. The movement of the clamping plate 215 drives the first clamping block 216 to move downward. The plane of the first clamping block 216 is no longer in contact with the plane of the second clamping block 217, and the limit of the rotating shaft 214 is released. At this time, the first spring and the torsion spring are released. The release of the first spring pushes the third hinged rod 206 to reset. The third hinged rod 206 resets and extracts the hydraulic oil in the sealing tube 210 through the first transmission tube 209, and cooperates The release of the torsion spring drives the second hinged rod 205 to rotate counterclockwise, and the volume of the hydraulic oil in the sealing tube 210 is reduced, thereby driving the push rod 211 and the rack 212 to move and reset. The rack 212 moves and drives the gear 213 to rotate in the opposite direction. The rotation of the gear 213 drives the rotating shaft 214, the first block 216 and the conveying plate 3 to rotate in the opposite direction and reset synchronously. Then the first spring is released, and the volume in the sealing box 207 is filled with hydraulic oil. The third hinged rod 206 contacts one end of the sealing box 207. At this time, the torsion spring has not been released, and the torsion spring will continue to release and drive the second hinged rod 205 to rotate counterclockwise. At this time, the second hinged rod 205 pulls the sealing box 207 to move through the third hinged rod 206, and the sealing box 207 drives the fourth hinged rod 208 to move.The fourth hinge rod 208 moves to drive the first hinge rod 204 to rotate counterclockwise along the rotating rod as the axis, and then the torsion spring is released, and the first hinge rod 204 and the second hinge rod 205 are reset.

[0031] On the basis of the above, if the goods that do not touch the second conveyor belt 110 are small cartons or small bags, they will continue to move forward. When the small cartons or small bags move to just below the suction cup 510, the electric push rod 507 is started, and the output end of the electric push rod 507 drives the rotating column 508 and the suction cup 510 to descend. It is worth mentioning that the transportation speed of small bags is relatively slow. The vertical groove and spiral groove of the guide groove 509 move downward and squeeze the protrusion in the circular through groove of the second fixed plate 504, so that the rotating column 508 and the suction cup 510 rotate and descend. When the goods are small bags, the inside of the small bags contains clothes and has a certain flexibility. The several support columns 514 at the bottom of the suction cup 510 will preferentially contact and squeeze the top of the small bag, and the surface of the small bag is squeezed. After that, the squeezed part area is sunken downward. It is worth mentioning that the elastic force of several fourth springs is relatively large. When several anti-pillars 514 are sunken downward, several fourth springs will not shrink, and the middle position of the squeezed part area on the top of the small bag will bulge upward, and the raised area of ​​the small bag is more easily contacted and fitted by the suction cup 510. At this time, the air pump 511 is started, and the suction end of the air pump 511 sucks air into the suction cup 510 through the second transmission pipe 512, and several suction holes 515 adsorb the raised area of ​​the small bag. After the adsorption is completed, the output end of the electric push rod 507 drives the rotating column 508 and the suction cup 510 to move upward. When the guide groove 509 moves upward, the vertical groove and the spiral groove of the guide groove 509 squeeze the circular through groove of the second fixed plate 504. The protrusion makes the rotating column 508, the suction cup 510 and the small bag rotate in the opposite direction and rise. At the same time, the second drive motor 5 is started, and the output end of the second drive motor 5 drives the threaded rod 505 to rotate. The threaded rod 505 drives the first adjustment plate 501 and the second adjustment plate 502 to move to the right along the sliding column 506 until the second adjustment plate 502 contacts the second collection box 7. The output shaft of the second drive motor 5 stops rotating. At this time, the protrusion in the circular through groove is located at the vertical groove below the guide groove 509. The output end of the electric push rod 507 is started again, and drives the rotating column 508, the suction cup 510 and the small bag to move downward and rotate again. If the small bag is in a folded state when placed on the first conveyor belt 108, then at this time the small bag moves downward and rotates During the movement, the small bag is affected by its own centrifugal force and is in an expanded state. As the suction cup 510 continues to descend, the protrusion in the circular through groove is located at the vertical groove above the guide groove 509, and the suction cup 510 stops rotating. At this time, the small bag is closer to the bottom of the second collection box 7. Since the small bag is still adsorbed by the suction cup 510, the four corners of the small bag will fall downward and fall on the bottom of the second collection box 7. Then the air pump 511 is turned off, and the several air suction holes 515 of the suction cup 510 stop adsorbing. The small bag falls downward from the adsorbed position, and its four corners are pushed to move and expand during the falling process, so as to avoid the small bag being folded together during sorting to generate extrusion friction, resulting in damage to the small bag, and causing the items in the small bag to be lost or damaged, and then collected manually.

[0032] When the small carton moves to the bottom of the suction cup 510, the output end of the electric push rod 507 drives the rotating column 508 and the suction cup 510 to move downward. It is worth noting that the conveying speed of the small carton is relatively slow. At this time, the electric push rod 507 is started, and the moving steps are consistent with the above. Because the surface of the small carton is relatively hard, when several anti-pillars 514 contact and squeeze the surface of the small carton, several anti-pillars 514 are forced to drive the contact rod 516 to move upward, and the fourth spring is compressed. When the contact rod 516 contacts the sensor, it indicates that there is a small carton under the suction cup 510. The sensor controls the output end of the electric push rod 507 to drive the rotating column 508 and the suction cup 510 to move upward and reset. At this time, the air pump 511 does not work and the suction cup 510 does not adsorb. Then the small carton is conveyed to the tail by the first conveyor belt 108 for manual collection.
