[0114] As Figure 4a to Figure 4d shown, the first lifting support 131 includes a first base 1311, two first support columns 1312 arranged at intervals on the first base 1311, and a first top cross beam 1313.

[0115] The first lifting assembly 132 includes a first driving member 1321 and a first lifting platform 1322, and the lifting conveying layer 140 is installed on the first lifting platform 1322. The first driving member 1321 is used to drive the first lifting platform 1322 and the lifting conveying layer 140 thereon to slide up and down along the height direction of the first support column 1312.

[0116] As Figure 4a to Figure 4eAs shown, between the two first support columns 1312, a second support column 1314 is further arranged.

[0117] The first driving member 1321 comprises a first lifting motor 1321a arranged on the first lifting platform 1322, a first driving gear 1321b connected with the motor output shaft of the first lifting motor 1321a, and a first rack 1321c arranged on the second support column 1314 in the height direction; the first lifting motor 1321a controls the rotation of the first driving gear 1321b to engage with the first rack 1321c, so as to lift or lower the first lifting platform 1322.

[0118] The two first support columns 1312 are each provided with a first sliding rail 1315; the two sides of the first lifting platform 1322 are respectively provided with a first sliding block 1323 for cooperating with the first sliding rail 1315, so as to realize the up-and-down sliding of the first lifting platform 1322 along the first support column 1312 in the height direction.

[0119] For example, when the output shaft of the first lifting motor 1321a drives the first driving gear 1321b to rotate clockwise, the first driving gear 1321b rises along the first rack 1321c, thereby driving the lifting conveying layer 140 to rise through the first lifting platform 1322; when the output shaft of the first lifting motor 1321a drives the first driving gear 1321b to rotate counterclockwise, the first driving gear 1321b descends along the first rack 1321c, thereby driving the lifting conveying layer 140 to descend through the first lifting platform 1322.

[0120] Alternatively, when the output shaft of the first lifting motor 1321a drives the first driving gear 1321b to rotate counterclockwise, the first driving gear 1321b rises along the first rack 1321c, thereby driving the lifting conveying layer 140 to rise through the first lifting platform 1322; when the output shaft of the first lifting motor 1321a drives the first driving gear 1321b to rotate clockwise, the first driving gear 1321b descends along the first rack 1321c, thereby driving the lifting conveying layer 140 to descend through the first lifting platform 1322.

[0121] In the first lifting mechanism in the embodiment, the lifting conveying layer 140 is lifted and lowered through the cooperation of the gear and the rack. The rack is arranged on the second support column 1314, which not only realizes the lifting and lowering, but also further strengthens the stress capacity of the first lifting mechanism, thereby ensuring the stable lifting and lowering of the lifting conveying layer 140.

[0122] Of course, the first lifting mechanism can also drive the lifting conveying layer 140 to rise and descend through the cooperation of the synchronous wheel and the synchronous belt, which is not limited here.

[0123] For example, Figure 4a to 4e and Figure 4bAs shown, the first slider 1323 is also fixedly connected with a first drag chain mounting seat 1324, one end of a first drag chain 1325 is fixedly connected to the first drag chain mounting seat 1324, and the other end of the first drag chain 1325 is fixedly connected to the middle part of the first lifting support 131.

[0124] As shown in the drawings, Figure 4d As shown, the first slider 1323 on the two first support columns 1312 is connected together through a first connecting plate 1326, the first connecting plate 1326 has a U-shaped first groove 1327, the first lifting platform 1322 is placed in the first groove 1327, the first connecting plate 1326 is fixedly connected with the first lifting platform 1322, and the first connecting plate 1326 further extends a first connecting rod 1328 towards both sides of the first groove 1327, the first connecting rod 1328 is fixedly connected with a first mounting plate 1329, and the first lifting motor 1321a is fixed to the first mounting plate 1329.

[0125] The first mounting plate 1329 is also fixedly connected with a first lifting motor controller 1321d, the first lifting motor controller 1321d can control the start or stop of the first lifting motor 1321a, and can also accurately control the rotating speed of the first lifting motor 1321a, so as to control the lifting and lowering of the lifting conveying layer 140 on the first lifting mechanism 130 and the lifting and lowering speed of the lifting conveying layer 140. The first lifting motor controller 1321d can also monitor the running state of the first lifting motor 1321a, and quickly stop the work of the first lifting motor 1321a when an abnormal situation occurs, so as to avoid damage to the first lifting motor 1321a.

[0126] In this embodiment, the lifting conveying layer 140 is fixedly connected with the two first sliders 1323 through the first connecting plate 1326, which can ensure the synchronous lifting and lowering of the two first sliders 1323, and further ensure the stable lifting and lowering of the lifting conveying layer 140.

[0127] As shown in the drawings, Figure 4d As shown, the bottom of the first lifting support 131 is provided with a first zero position sensor 1316, and the top of the first lifting support 131 is provided with a first limit position sensor 1317.

[0128] When the first zero position sensor 1316 detects the lifting conveying layer 140, it indicates that the lifting conveying layer 140 has reached the bottom of the first lifting mechanism 130, at this time, the lifting conveying layer 140 is butt jointed with the empty box conveying layer 150, that is, the lifting conveying layer 140 and the empty box conveying layer 150 are at the same height, so that the empty box 400 on the empty box conveying layer 150 can be successfully conveyed to the lifting conveying layer 140. The accuracy of conveying the empty box 400 between the lifting conveying layer 140 and the empty box conveying layer 150 is ensured.

[0129] When the first limit position sensor 1317 detects the lifting conveying layer 140, it indicates that the lifting conveying layer 140 has reached the topmost part of the first lifting mechanism 130, at this time, the lifting conveying layer 140 is docked with the buffer conveying layer 120, that is, the lifting conveying layer 140 and the buffer conveying layer 120 are at the same height, so that the full cartridge 500 on the lifting conveying layer 140 can be successfully conveyed to the buffer conveying layer 120. The accuracy of conveying the full cartridge 500 between the lifting conveying layer 140 and the buffer conveying layer 120 is ensured.

[0130] Further, the arrangement of the first zero position sensor 1316 and the first limit position sensor 1317 can also prevent the lifting conveying layer 140 from continuing to descend when it has reached the bottommost part of the first lifting mechanism 130, and prevent the lifting conveying layer 140 from continuing to ascend when it has reached the topmost part of the first lifting mechanism 130, thereby improving the safety of the first lifting mechanism.

When the first docking photoelectric sensor 141 receives the light reflected by the first docking reflector plate 123, it indicates that the lifting conveying layer 140 has been lifted into position.

[0132] In other embodiments, the positions of the docking photoelectric sensor and the docking reflector plate can be interchanged, which is not limited here. For example, the two ends of the lifting conveying layer 140 along the conveying direction are provided with a second docking reflector plate, and correspondingly, the left buffer conveying layer 121, the right buffer conveying layer 122, the left empty cartridge conveying layer 151, the right empty cartridge conveying layer 152, the left full cartridge conveying layer 161 and the right full cartridge conveying layer 162 are provided with a second docking photoelectric sensor corresponding to the second docking reflector plate at the end facing the first lifting mechanism 130.

[0134] ​The second interface photoelectric sensor emits light, the second interface reflector 4 is used for receiving and reflecting the light emitted by the second interface photoelectric sensor, and the second interface photoelectric sensor can also be used for receiving the light reflected by the second interface reflector. When the second interface photoelectric sensor receives the light reflected by the second interface reflector, it indicates that the lifting conveying layer 140 is lifted to the position. The accuracy of the interface between the lifting conveying layer 140 on the first lifting mechanism 130 and the empty box conveying layer 150, the full box conveying layer 160 or the buffer conveying layer 120 is ensured.
