The goods storage and retrieval efficiency is high, and the demand for large-scale storage and retrieval of goods is met.

[0032] like Figure 5As shown, specifically, the cargo hanging mechanism includes a first circulating cargo hanging component 3, a second circulating cargo hanging component 4 and a first driving mechanism 5, the first circulating cargo hanging component 3 and the second circulating cargo hanging component 4 are respectively arranged on both sides of the elastic pushing mechanism, and the first circulating cargo hanging component 3 and the second circulating cargo hanging component 4 cooperate with each other to suspend and support the cargo, and the first driving mechanism 5 is used to drive the first circulating cargo hanging component 3 and the second circulating cargo hanging component 4 to rotate synchronously and cyclically.

[0033] The goods are arranged between the first circulation cargo hanging assembly 3 and the second circulation cargo hanging assembly 4. A flange is arranged around the top of the goods. The first circulation cargo hanging assembly 3 and the second circulation cargo hanging assembly 4 cooperate with each other to support the flange of the goods, thereby hanging the goods above the elastic push mechanism. The first driving mechanism 5 drives the first circulation cargo hanging assembly 3 and the second circulation cargo hanging assembly 4 to rotate synchronously, so that the first circulation cargo hanging assembly 3 and the second circulation cargo hanging assembly 4 move up and down with the goods.

[0034] Preferably, the first circulating cargo hanging assembly 3 includes a first circulating conveyor belt 6, on which a plurality of first suspension supports are arranged at intervals; the second circulating cargo hanging assembly 4 includes a second circulating conveyor belt 7, on which a plurality of second suspension supports are arranged at intervals, and the second suspension supports correspond to the first suspension supports one by one to support the flange of the cargo. A plurality of first suspension supports can be arranged on the first circulating conveyor belt 6, and a plurality of second suspension supports can be arranged on the second circulating conveyor belt 7. The second suspension supports cooperate with the first suspension supports to form a multi-layer structure, and each layer of the structure can hang cargo, so as to facilitate the up and down movement of cargo.

[0035] like Figure 3 As shown, the first suspension support and the second suspension support both include a suspension support bar 8, the end of the suspension support bar 8 is provided with a slider 9, and the frame 1 is provided with a limit slide rail 10 adapted to the slider 9. The suspension support bar 8 is installed on the first circulating conveyor belt 6 and the second circulating conveyor belt 7, and the suspension support bar 8 has a certain length. A pair of suspension support bars 8 can be provided with multiple goods. In specific use, for the suspension support bar 8 installed on the first circulating conveyor belt 6, both ends of the suspension support bar 8 can be connected to a first circulating conveyor belt 6, and the two first circulating conveyor belts 6 rotate synchronously, and the first driving mechanism 5 only needs to directly drive one of the first circulating conveyor belts 6 to rotate; for the suspension support bar 8 installed on the second circulating conveyor belt 7, both ends of the suspension support bar 8 can be connected to a second circulating conveyor belt 7, and the two second circulating conveyor belts 7 rotate synchronously, and the first driving mechanism 5 only needs to directly drive one of the second circulating conveyor belts 7 to rotate, so as to ensure the stability of the goods.

[0036] A limit slide rail 10 is arranged on the frame 1, and the slider 9 at the end of the suspension support bar 8 cooperates with the limit slide rail 10 to prevent the first circulating conveyor belt 6 and the second circulating conveyor belt 7 from running off, so that the goods can be stably moved up and down. The limit slide rail 10 is in a strip shape, and both ends of the limit slide rail 10 are open. Both ends of the limit slide rail 10 are provided with guide parts, and the guide parts are V-shaped, which can make the first circulating conveyor belt 6 and the second circulating conveyor belt 7 work more stably.

[0037] The first driving mechanism 5 includes a first driving motor 11, which is mounted on the frame 1. A worm 12 is provided at the output end of the first driving motor 11. The two sides of the worm 12 are respectively connected to the first turbine 13 and the second turbine 14. The first turbine 13 is connected to the first circulating conveyor belt 6, and the second turbine 14 is connected to the second circulating conveyor belt 7. Specifically, the first turbine 13 is connected to the first gear, the first circulating conveyor belt 6 is provided with a second gear, the second gear is coaxial with the first gear, and the second gear rotates synchronously with the first gear. The second turbine 14 is connected to the third gear, the second circulating conveyor belt 7 is provided with a fourth gear, the fourth gear is coaxial with the third gear, and the fourth gear rotates synchronously with the third gear. A first infrared sensor is provided on the frame 1. The first infrared sensor is used to detect the position of the suspension support bar 8. When the suspension support bar 8 moves to a certain position above the push plate 15, the first infrared sensor detects the suspension support bar 8, and then the first driving motor 11 stops running, so that the first circulating conveyor belt 6 and the second circulating conveyor belt 7 stop rotating.

[0038] like Figure 6 and Figure 7As shown, the elastic pushing mechanism includes a pushing plate 15 and a second driving mechanism 16. The pushing plate 15 is slidably arranged on the frame body 1. The pushing plate 15 is provided with a restoring spring 17 for pushing the goods. The second driving mechanism 16 is used to drive the pushing plate 15 to slide on the frame body 1. The restoring spring 17 is tiltedly arranged on the pushing plate 15, and the middle part of the restoring spring 17 is rotatably connected to the pushing plate 15. The top of the restoring spring 17 is tilted to the right. The restoring spring 17 can rotate within a certain angle range. The bottom end of the restoring spring 17 is provided with a counterweight block, so that the restoring spring 17 automatically returns to the tilted state; in addition, the restoring spring 17 can also be connected to the pushing plate 15 by a torsion spring to ensure that the restoring spring 17 can automatically return to the tilted state. When a force is applied to the top surface of the top of the restoring spring sheet 17, the restoring spring sheet 17 is pressed to rotate downward, and when the force is eliminated, the restoring spring sheet 17 automatically returns to its original position; when a force is applied to the bottom surface of the top of the restoring spring sheet 17, the restoring spring sheet 17 does not rotate. When the second driving mechanism 16 drives the push plate 15 to slide to the right, the bottom surface of the top of the restoring spring sheet 17 contacts the goods, and the restoring spring sheet 17 pushes the goods to slide on the suspension support bar 8; when the second driving mechanism 16 drives the push plate 15 to slide to the left and return to its original position, the top surface of the top of the restoring spring sheet 17 contacts the goods. Since the goods have a certain mass, the restoring spring sheet 17 is pressed to rotate downward, and the restoring spring sheet 17 cannot push the goods to slide on the suspension support bar 8. A second infrared sensor is set at the right end of the push plate 15, and the second infrared sensor is used to detect the sliding distance of the push plate 15 to the right, ensuring that the goods at the rightmost end can be shipped smoothly; a third infrared sensor is set at the left end of the push plate 15, and the third infrared sensor is used to detect the sliding distance of the push plate 15 to the left, ensuring that the push plate 15 can return to its original position.

[0039] Preferably, the push plate 15 is provided with a plurality of recovery springs 17, and the number of the recovery springs 17 matches the number of goods above it. There are a plurality of goods on a pair of suspension support bars 8, and there is a gap between adjacent goods. The recovery springs 17 can extend into the gap to apply thrust to the goods. When the push plate 15 slides to the right, each recovery spring 17 pushes a piece of goods to slide on the suspension support bar 8, and all the goods slide to the right. The goods at the rightmost end slide off the suspension support bar 8 to complete the shipment, and the goods next to the rightmost end fill the rightmost position; then the push plate 15 slides to the left, and the recovery spring 17 rotates downward under pressure, and cannot push the goods to slide, that is, the position of the goods remains unchanged, and the push plate 15 and the recovery spring 17 return to their original positions. After the goods are shipped, the goods are added from the left end of the suspension support bar 8. This method can ensure that the goods are shipped one by one and improve the shipping efficiency.

[0040] The second driving mechanism 16 includes a second driving motor 18, and a synchronous belt assembly 19 is provided at the output end of the second driving motor 18, and the synchronous belt assembly 19 is connected to the push plate 15. The synchronous belt assembly 19 includes a toothed belt, a first pulley and a second pulley, the toothed belt is connected to the first pulley and the second pulley, the first pulley is connected to the second driving motor 18, and the toothed belt is fixedly connected to the push plate 15 to ensure that the push plate 15 can slide smoothly.

[0041] like Figure 4 As shown, the end of the elastic pushing mechanism is provided with a check block 20 for blocking the return of the goods. The check block 20 is located above the right end of the pushing plate 15. The check block 20 can be set on both sides above the pushing plate 15, or can be set directly above the pushing plate 15. The right end of the pushing plate 15 can be shorter than the right end of the suspension support bar 8, which can directly push the goods out of the goods. Preferably, the right end of the pushing plate 15 is flush with the right end of the suspension support bar 8. The pushing plate 15 slides to the right to make the goods slide off the suspension support bar 8, and the goods fall onto the pushing plate 15. Then the second driving mechanism 16 drives the pushing plate 15 to slide to the left. The check block 20 can resist the goods, so that the goods slide off the pushing plate 15 to complete the shipment, and prevent the goods from moving to the left with the pushing plate 15. The check block 20 is rotatably arranged on the frame 1, and the check block 20 is provided with an inclined guide surface 21. The guide surface 21 can make the goods fall slowly onto the push plate 15, improving the safety of the goods. The goods on the storage shelf are shipped layer by layer from bottom to top, and the goods are replenished through the left end of the hanging support bar 8. The edge of the push plate 15 is provided with a limit edge, which can prevent the goods from falling from the edge of the push plate 15.

[0042] The working method of the storage rack of the present invention is as follows: the first driving mechanism 5 drives the first circulating conveyor belt 6 and the second circulating conveyor belt 7 to rotate synchronously, and the hanging support strips 8 on the first circulating conveyor belt 6 and the second circulating conveyor belt 7 move downward with the goods. When the goods move to a certain position above the push plate 15, the first circulating conveyor belt 6 and the second circulating conveyor belt 7 stop rotating, and the second driving mechanism 16 drives the push plate 15 to slide to the right, and each return spring sheet 17 pushes a good to slide on the hanging support strip 8, so that all the goods slide to the right, and the good at the rightmost end gradually slides off the hanging support strip 8 and slowly The goods at the rightmost end slowly fall onto the push plate 15, and the goods next to the rightmost end fill the empty space at the rightmost end; after the goods at the rightmost end completely slide off the suspension support bar 8 and fall onto the push plate 15, the second drive mechanism 16 drives the push plate 15 to slide leftward and return to its original position, and the check block 20 resists the goods, so that the goods gradually slide off the push plate 15, and at the same time, the return spring sheet 17 moves leftward with the push plate 15, and the return spring sheet 17 rotates downward under the pressure of the goods, and it cannot push the goods to slide, and finally the return spring sheet 17 returns to its original position, and the goods completely slide off the push plate 15, thereby completing the shipment. The present invention has a simple structure, can effectively protect the safety of goods, and realizes the rapid shipment of goods.

[0043] The present invention is not limited to the above optional implementations, and anyone can derive other various forms of products under the enlightenment of the present invention.
