[0022] Preferably, a special loading and unloading method for IoT-controlled smart logistics is as follows:

[0023] S1: Multiple parcels are transported via a conveyor belt mechanism, and an external camera is used to observe the parcels on the conveyor belt mechanism to determine whether the parcels are fragile items or ordinary items;

[0024] S2: Use the shovel head to push the express off the conveyor belt mechanism;

[0025] S3: The first motor drives the first swing arm to swing, so that the first swing arm moves the rods on both sides of the rectangular box to move along the slide grooves on both sides of the rectangular frame, thereby driving the rectangular box to move out of the rectangular frame, and at the same time, driving the cylindrical gear to move. When the cylindrical gear moves to engage with the spur rack, the first motor drives the first swing arm to continue to swing, thereby driving the cylindrical gear to continue to move, thereby causing the cylindrical gear to rotate, and then driving the rectangular box to rotate, so that the rectangular box is tilted at a certain angle. At this time, the opening above the rectangular box is more convenient for the express on the conveyor belt mechanism to fall into the interior of the rectangular box;

[0026] S4: The motor on the connecting bracket drives the small conveyor belt mechanism to rotate, thereby tilting the small conveyor belt mechanism at a certain angle, making it easier for the express to fall into storage boxes at different heights; at the same time, the motor on the supporting bottom plate drives the screw D of the first screw moving mechanism to rotate, thereby driving the slider D of the first screw moving mechanism to move, thereby driving the connecting bracket and the small conveyor belt mechanism to move, thereby facilitating more orderly storage of the express inside the storage box and better utilizing the storage space inside the storage box;

[0027] S5: When it is necessary to place a larger object, first, the third swing rod is driven to swing by the motor on the supporting square plate, thereby driving the connecting block to descend, and then driving the suction cup to be adsorbed on the square support plate to prevent the supporting square plate from moving; the motor on one of the third screw moving mechanisms drives the screws C of the two third screw moving mechanisms to rotate, and then drives the sliders C of the two third screw moving mechanisms to move, thereby driving the square plate and the square bottom plate to move in opposite directions to each other, thereby increasing the space between the square plate and the square bottom plate, thereby making it easier for people to lift and place larger objects on the equipment; if the object is too large and more space is needed, the second motor drives the rectangular frame to rotate along the arc-shaped slide groove on the square plate, and at the same time, the fourth motor drives the rectangular frame to rotate along the arc-shaped slide groove on the square bottom plate, thereby expanding the space between the rectangular frame and the rectangular frame, thereby making it easier to place larger objects;

[0028] S6: The connecting plate is extended and retracted to push the square support plate upward, so that the equipment on the square support plate is lifted as a whole to a position where it can be moved to a loading truck. Subsequently, the motor D of the second screw moving mechanism drives the screw B of the second screw moving mechanism to rotate, thereby driving the two sliders B of the second screw moving mechanism to move, thereby driving the two sliding rods to release the second electric wheel, so that the second electric wheel can drive the supporting square plate and other equipment on the supporting square plate to move to the loading and unloading truck, thereby reducing the labor of manual handling;

[0029] S7: The express is then removed from the device manually.

[0030] The beneficial effects of the present invention compared with the prior art are:

[0031] 1. The present invention can improve storage efficiency and protect fragile items by differentiating between them. At the same time, the present invention can increase storage space by deformation, so as to place large express items and reduce labor. The present invention can also directly transport express items into the loading vehicle, making it convenient for people to load express items.

[0032] 2. One of the second swing rods drives the third motor to swing, thereby pushing a storage box at the corresponding position to move out of the rectangular frame, so as to facilitate the fragile express delivery on the small conveyor belt mechanism to fall into the storage box. Since a support plate is slidably installed inside the storage box, and a spring is fixedly connected to the lower end surface of the support plate, the spring and the support plate are used to absorb shock to the express delivery placed in the storage box to prevent damage to the express delivery.

[0033] 3. The motor D of the second screw moving mechanism drives the screw B of the second screw moving mechanism to rotate, thereby driving the two sliders B of the second screw moving mechanism to move, thereby driving the two sliding rods to release the second electric wheel, so that the second electric wheel can drive the supporting square plate and other equipment on the supporting square plate to move to the loading and unloading vehicle, thereby reducing the labor of manual handling.

[0069] The present invention also provides a special loading and unloading method for IoT-controlled smart logistics, as follows:

[0070] S1: Multiple parcels are conveyed via the conveyor belt mechanism 1, and the parcels on the conveyor belt mechanism 1 are observed by an external camera to determine whether the parcels are fragile items or ordinary items;

[0071] S2: Use the shovel head 317 to push the express off the conveyor belt mechanism 1;

[0072] S3: The first motor 207 drives the first swinging rod 205 to swing, so that the first swinging rod 205 moves the rods on both sides of the rectangular box 201 along the slide grooves on both sides of the rectangular frame 202, thereby driving the rectangular box 201 to move out of the rectangular frame 202, and at the same time, driving the cylindrical gear 204 to move. When the cylindrical gear 204 moves to engage with the spur rack 203, the first motor 207 drives the first swinging rod 205 to continue to swing, thereby driving the cylindrical gear 204 to continue to move, thereby causing the cylindrical gear 204 to rotate, and then driving the rectangular box 201 to rotate, so that the rectangular box 201 is tilted at a certain angle.

[0073] S4: The motor on the connecting bracket 212 drives the small conveyor belt mechanism 213 to rotate, thereby tilting the small conveyor belt mechanism 213 at a certain angle, which facilitates the dropping of express packages into the storage boxes 218 at different heights; at the same time, the motor on the supporting base plate 210 drives the screw D of the first screw moving mechanism 211 to rotate, thereby driving the slider D of the first screw moving mechanism 211 to move, thereby driving the connecting bracket 212 and the small conveyor belt mechanism 213 to move, thereby facilitating the more orderly storage of express packages into the storage box 218, and better utilizing the storage space inside the storage box 218;

[0074] S5: When it is necessary to place a larger object, first, the motor on the supporting square plate 308 drives the third swing rod 310 to swing, thereby driving the connecting block 311 to descend, and then driving the suction cup 312 to be adsorbed on the square support plate 301 to prevent the supporting square plate 308 from moving; the motor on one of the third screw moving mechanisms 309 drives the screws C of the two third screw moving mechanisms 309 to rotate, thereby driving the sliders C of the two third screw moving mechanisms 309 to move, thereby driving the square plate 208 and the square bottom plate 221 to move toward each other.

[0076] S7: The express is then removed from the device manually.

[0077] Working principle:

[0078] The present invention can improve storage efficiency and protect fragile items by distinguishing between fragile items and ordinary items. At the same time, the present invention can increase storage space by deformation, so that large express items can be placed, reducing labor. In addition, the present invention can directly transport express items to the inside of the loading vehicle, making it convenient for people to load express items.

[0079] Multiple parcels are conveyed via the conveyor belt mechanism 1, and the parcels on the conveyor belt mechanism 1 are observed by an external camera to determine whether the parcels are fragile items or ordinary items;

[0080] When the express is pushed, the fourth screw moving mechanism 315, the telescopic frame 316 and the shovel head 317 are driven up and down by the extension and contraction of the second electric cylinder 314, so that the shovel head 317 can push the express at different heights; the servo motor B of the fourth screw moving mechanism 315 drives the screw D of the fourth screw moving mechanism 315 to rotate, thereby driving the slider D of the fourth screw moving mechanism 315 to move, thereby driving the telescopic frame 316 and the shovel head 317 to move to the express at the corresponding position, and then the telescopic frame 316 is extended to drive the shovel head 317 to move to the side of the express, and then the motor on the telescopic frame 316 drives the shovel head 317 to rotate, so that the shovel head 317 contacts the express, and then the telescopic frame 316 is extended to drive the shovel head 317 to move, so that the shovel head 317 drives the express to move to the vicinity of the equipment, so that the express is stored conveniently;

[0081] When it is necessary to load ordinary express from the conveyor belt mechanism 1 onto the device, first, the first swing arm 205 is driven to swing by the first motor 207, so that the first swing arm 205 moves the rods on both sides of the rectangular box body 201 along the slide grooves on both sides of the rectangular frame body 202, thereby driving the rectangular box body 201 to move out of the rectangular frame body 202. At the same time, it drives the cylindrical gear 204 to move. When the cylindrical gear 204 moves to mesh with the spur rack 203, the first swing arm 205 is driven by the first motor 207 to continue to swing, thereby driving the cylindrical gear 204 to continue to move, thereby causing the cylindrical gear 204 to rotate, and then driving the rectangular box body 201 to rotate, so that the rectangular box body 201 is tilted at a certain angle. At this time, the opening above the rectangular box body 201 is more convenient for the express on the conveyor belt mechanism 1 to fall into the interior of the rectangular box body 201;

[0082] In order to better preserve the fragile express items, it is necessary to place the fragile express items neatly inside different storage boxes 218. After the express items are moved to the small conveyor belt mechanism 213, the motor on the connecting bracket 212 drives the small conveyor belt mechanism 213 to rotate, thereby tilting the small conveyor belt mechanism 213 to a certain angle, which facilitates the express items to fall into the storage boxes 218 at different heights. At the same time, the motor on the supporting base plate 210 drives the screw D of the first screw moving mechanism 211 to rotate, thereby driving the slider D of the first screw moving mechanism 211 to move, thereby driving the connecting bracket 212 and the small conveyor belt mechanism 213 to move, thereby facilitating the neat storage of the express items inside the storage box 218 and making better use of the storage space inside the storage box 218.

[0083] The third motor 217 is driven to swing by one of the second swinging rods 216, thereby pushing a storage box 218 at the corresponding position to move out of the rectangular frame 214, so as to facilitate the fragile express delivery on the small conveyor belt mechanism 213 to fall into the storage box 218. Since a support plate 219 is slidably installed inside the storage box 218, and a spring 220 is fixedly connected to the lower end surface of the support plate 219, the spring 220 and the support plate 219 can reduce the shock of the express delivery placed in the storage box 218 to prevent the express delivery from being damaged.

[0084] If a larger object needs to be placed, first, the motor on the supporting square plate 308 drives the third swing rod 310 to swing, thereby driving the connecting block 311 to descend, and then driving the suction cup 312 to be adsorbed on the square support plate 301 to prevent the supporting square plate 308 from moving; the motor on one of the third screw moving mechanisms 309 drives the screws C of the two third screw moving mechanisms 309 to rotate, thereby driving the sliders C of the two third screw moving mechanisms 309 to move, thereby driving the square plate 208 and the square bottom plate 221 to move in opposite directions, thereby increasing the space between the square plate 208 and the square bottom plate 221, thereby making it easier for people to lift and place larger objects on the device;

[0085] If the item is too large and more space is needed, the second motor 209 drives the rectangular frame 202 to rotate along the arc-shaped slide groove on the square plate 208. At the same time, the fourth motor 222 drives the rectangular frame 214 to rotate along the arc-shaped slide groove on the square bottom plate 221, thereby expanding the space between the rectangular frame 202 and the rectangular frame 214, making it easier to place larger items.

[0086] When assembling goods, at this moment, because the loading truck bucket is too long, under normal circumstances, it is necessary to manually use a cart to pick up the express from the ground, then push the cart to the loading truck, and then manually take the express from the cart and put it on the loading truck. The present invention uses the first electric wheel 302 to drive the entire device to move; when it is necessary to unload goods, at this moment the first electric wheel 302 is in a fixed state, and the connecting plate 303 is extended and retracted to push the square support plate 301 to lift the entire device on the square support plate 301 to a position where it can be moved to the loading truck. Subsequently, the motor D of the second screw moving mechanism 305 drives the screw B of the second screw moving mechanism 305 to rotate, thereby driving the two sliders B of the second screw moving mechanism 305 to move, thereby driving the two sliding rods 306 to release the second electric wheel 307, so that the second electric wheel 307 can drive the supporting square plate 308 and other equipment on the supporting square plate 308 to move to the loading and unloading truck, thereby reducing the labor of manual handling;

[0087] When unloading fragile items from the storage box 218, the opening and closing door 215 is opened manually, and the second swing rod 216 drives the third motor 217 to swing, so that the third motor 217 drives the storage box 218 to move out of the rectangular frame 214 from the end of the opening and closing door 215, making it convenient for manual removal of the express delivery from the storage box 218.

[0088] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

At this moment, the opening above the rectangular box (201) is more convenient for the express on the conveyor belt mechanism (1) to fall into the interior of the rectangular box (201); S4: The small conveyor belt mechanism (213) is driven to rotate by the motor on the connecting bracket (212), so that the small conveyor belt mechanism (213) is tilted at a certain angle, so that the express delivery can be dropped into the storage box (218) at different heights; at the same time, the motor on the supporting bottom plate (210) drives the screw D of the first screw moving mechanism (211) to rotate, thereby driving the slider D of the first screw moving mechanism (211) to move, thereby driving the connecting bracket (212) and the small conveyor belt mechanism (213) to move, thereby facilitating the more orderly storage of the express delivery into the storage box (218), and better utilizing the storage space inside the storage box (218); S5: When a larger object needs to be placed, first, the motor on the supporting square plate (308) drives the third swing rod (310) to swing, thereby driving the connecting block (311) to descend, thereby driving the suction cup (312) to be adsorbed on the square support plate (301) to prevent the supporting square plate (308) from moving; the motor on one of the third screw moving mechanisms (309) drives the screws C of the two third screw moving mechanisms (309) to rotate, thereby driving the sliders C of the two third screw moving mechanisms (309) to move, thereby driving the square plate (208) and the square bottom plate (221) toward each other. The rectangular frame (202) is moved in opposite directions, thereby increasing the space between the square plate (208) and the square bottom plate (221), thereby making it easier for people to lift and place larger items on the device; if the item is too large and further space is required, the second motor (209) drives the rectangular frame (202) to rotate along the arc-shaped sliding groove on the square plate (208), and at the same time, the fourth motor (222) drives the rectangular frame (214) to rotate along the arc-shaped sliding groove on the square bottom plate (221), thereby expanding the space between the rectangular frame (202) and the rectangular frame (214), thereby making it easier to place larger items; S6: The connecting plate (303) is extended and retracted to push the square support plate (301) to lift the equipment on the square support plate (301) so that the equipment on the square support plate (301) is lifted as a whole to a position where it can be moved to a loading vehicle. Subsequently, the motor D of the second screw moving mechanism (305) drives the screw B of the second screw moving mechanism (305) to rotate, thereby driving the two sliders B of the second screw moving mechanism (305) to move, thereby driving the two sliding rods (306) to release the second electric wheel (307), thereby facilitating the second electric wheel (307) to drive the supporting square plate (308) and other equipment on the supporting square plate (308) to move to the loading and unloading vehicle, thereby reducing the labor of manual handling; S7: The express is then removed from the device manually.
