The goods 7 are lifted and lowered in the lifting bin 11 under the drive of the lifting structure 3. The lifting structure 3 is positioned and connected to the lifting bin 11 through a mounting plate 113 provided on the upper side of the lifting bin 11. The pickup cage 37 is connected to a positioning lifting structure 4, a lateral clamping structure 5 and a pushing structure 6.

The first motor 31 drives the first synchronous pulley 33, and then drives the first synchronous belt 34, the drive shaft 32 and the spiral column 35. There are four spiral columns 35, which are arranged in the height direction of the lifting warehouse 11. There are four spiral blocks 36, which are respectively installed on the top four corners of the cargo cage 37. The spiral columns 35 drive the cargo cage 37 to perform lifting movements through the spiral blocks 36.

[0032] The limiting structure of the lifting compartment 11 includes a first limiting plate 111 and a second limiting plate 112. Figure 4 As shown, the side of the locking and lifting structure 4 has a first locking frame 41 and a second locking frame 42. When the cargo cage 37 descends to the bottom of the lifting bin 11, the first locking frame 41 abuts against the first limit plate 111, and the second locking frame 42 abuts against the second limit plate 112. The locking and lifting structure 4 also includes a vertical slide rail 43, a connecting plate 45, a guide post 46, a first spring 47, and a vertical rack and pinion assembly 48. The lateral clamping structure 5 includes a horizontal rack and pinion assembly 51. The second locking frame 42 is slidably connected to the side of the cargo cage 37 via the vertical slide rail 43. The guide post 46 and the first spring 47 are connected between the connecting plate 45 and the first locking frame 41. The connecting plate 45 is disposed in the second locking frame 42 and drives the connecting clamp 56 via the vertical rack and pinion assembly 48 and the horizontal rack and pinion assembly 51. Preferably, the length of the first spring 47 is less than the distance between the first locking frame 41 and the second locking frame 42. Further preferably, the present invention also includes a horizontal conveying structure 2, comprising a first roller 21 on the underside of the lift 11. The first roller 21 is rotatably connected to the underside of the lift 11 via a roller bracket 22. Furthermore, a second roller 373 is connected to the underside of the cargo cage 37. A U-shaped groove 372 is defined between adjacent second rollers 373. The shape of the U-shaped groove 372 matches that of the first roller 21, allowing the first roller 21 to extend from the U-shaped groove 372 when the cargo cage 37 falls to the underside of the lift 11. The provision of the horizontal conveying structure 2 facilitates the sliding conveyance of the cargo 7.

[0033] like Figure 5As shown, the vertical gear rack assembly 48 includes a vertical slide bar 481, a first vertical slide rail 482, a vertical rack 483, a vertical gear 484, and a gear shaft 485. The vertical slide bar 481 is arranged parallel to the guide column 46 and the first spring 47. One side of the first vertical slide rail 482 is fixedly connected to the connecting plate 45, and the other side is slidably connected to the vertical slide bar 481. The vertical rack 483 is arranged parallel to the upper part of the vertical slide bar 481. The vertical gear 484 is meshed with the vertical rack 483, and the gear shaft 485 is fixedly connected to the vertical gear 484. A first horizontal slide rail 53 is provided on the connecting plate 45. A first push plate 52 is slidably connected to the first horizontal slide rail 53. The first push plate 52 drives the connecting clamping plate 56, as shown in FIG. Figure 7 As shown, the clamping plate 56 is connected to the chute plate 55, and the first push plate 52 is connected to the chute plate 55 through the U-shaped connecting plate 54. The forward and backward movement of the first push plate 52 can drive the clamping plate 56 to move forward and backward synchronously. Figure 6 As shown, the side wall of the cargo cage 37 has a lifting slot 371 that cooperates with the U-shaped connecting plate 54. The U-shaped connecting plate 54 can pass through the lifting slot 371 and move up and down under the drive of the first push plate 52, thereby driving the clamping plate 56 to move up and down. The horizontal gear rack assembly 51 includes a horizontal slide bar 511, a horizontal slide rail 512, a horizontal rack 513, and a horizontal gear 514. The horizontal slide bar 511 is fixedly connected to the first push plate 52, and the horizontal slide rail 512 is fixedly connected to the connecting plate 45. The horizontal slide bar 511 and the horizontal slide rail 512 are both connected to the first push plate 52. The outer end of the horizontal slide bar 511 has a horizontal rack 513. The gear shaft 485 has a horizontal gear 514 at a position corresponding to the horizontal rack 513. The horizontal gear 514 meshes with the horizontal rack 513.

[0034] At the same time, if Figure 6 As shown, the side wall of the cargo cage 37 is provided with a lifting slide 371 that cooperates with the U-shaped connecting plate 54 to ensure that the clamping plate 56 can move up and down under the drive of the U-shaped connecting plate 54.

[0035] like Figure 4 As shown, the pushing structure 6 includes a mounting plate 61, a second motor 62, a driving shaft 63, a driven shaft 64, a second synchronous pulley 65 and a second synchronous belt 66. The mounting plate 61 is connected to the cargo cage 37, and the driving shaft 63 and the driven shaft 64 are connected between the mounting plates 61. The second motor 62 drives the pushing plate 67 fixedly connected to the second synchronous belt 66 through the driving shaft 63, the driven shaft 64, the second synchronous pulley 65 and the second synchronous belt 66.

[0036] The embodiment of the present invention further includes a pop-up retraction assembly 57, such as Figure 8 and Figure 9As shown, the pop-up retraction assembly 57 includes a slide column 571, a slider 572, a second guide column 573, a second spring 574, a first magnet 575, a pressure rod 576, a second magnet 577, and a third spring 578. The slide column 571 is connected to the inner side of the pickup cage 37 and is located on both sides of the slide plate 55. The slide plate 55 is telescopically connected to the slide column 571 through the second guide column 573. The pressure rod 576 is telescopically connected to the slide column 571 and faces one side of the push plate 67. The second guide column 573 is sleeved with the second spring 574, and its end facing the pressure rod 576 is connected to the first magnet 575. The pressure rod 576 is sleeved with the third spring 578, and a second magnet 577 is provided at a position corresponding to the second guide column 573. The magnetic poles of the first magnet 575 and the second magnet 577 on the side close to the storage bin 12 attract each other, while the magnetic poles of the first magnet 575 and the second magnet 577 on the side away from the storage bin 12 repel each other. Preferably, the slide column 571 is provided with a connecting groove 5711 and a pressure rod groove 5712. The mounting plate 61 is fixedly connected to the slider 572 through the connecting groove 5711. The pressure rod 576 extends through the pressure rod groove 5712. The mounting plate 61 is connected to the pickup cage 37 through the slider 572.

[0037] like Figure 7 As shown, the U-shaped connecting plate 54 is connected to the clamping plate 56 via a slide plate 55. The slide plate 55 has a rectangular opening 551 and a horizontal slide 552. The clamping plate 56 is slidably connected to the horizontal slide 552. The two ends of the push plate 67 pass through the rectangular opening 551 and are clamped in the slide plate 55. Preferably, the two ends of the push plate 67 have clamping slides 671. The clamping slides 671 are slidably connected to the second slider 68, and the second slider 68 is fixedly connected to the clamping plate 56.

[0038] In a specific embodiment of the present invention, in the initial state, the cargo cage 37 is located in the upper half of the lifting warehouse 11, the first spring 47 bears the weight of the lateral clamping structure 5, the pushing structure 6 and part of the positioning lifting structure and is in a compressed state, the distance between the first positioning frame 41 and the second positioning frame 42 is small, the slide plate 55 and the clamping plate 56 in the lateral clamping structure 5 are in the pushing state, the U-shaped connecting plate 54 is at the lower part of the lifting slide 371, and the pressure rod 576 is in the extended state.

[0039] When a cargo cage is needed to pick up goods, the first motor 31 is started, and through the drive shaft 32, the first synchronous pulley 33 and the first synchronous belt 34, the four spiral columns 35 fixedly connected to the drive shaft 32 are driven to rotate synchronously. The spiral columns 35 are engaged with the threads of the threaded block 36, driving the cargo cage 37 fixedly connected to the threaded block 36 to move downward.

[0040] The first locking frame 41 is fixedly connected to the side of the picking cage 37 and the second limiting plate 112 is stopped. At this time, the first locking frame 41 fixedly connected to the side of the picking cage 37 continues to move downward with the rotation of the spiral column. The guide column 46 fixedly connected to the second locking frame 42 through the connecting plate 45 slides upward relative to the first locking frame 41. The first spring 47 recovers from the compressed state and gradually extends. The vertical rack 483 fixedly connected to the first locking frame 41 through the vertical slide bar 481 moves downward in the vertical direction relative to the vertical gear 484. The vertical rack 483 drives the vertical gear 484 to rotate through the gear rack meshing, and then drives the gear shaft 485 to rotate synchronously, and meshes with the second rack 513 through the second gear 514, driving the horizontal slide bar 511 and the first push plate 52 fixedly connected thereto to retract, thereby driving the U-shaped connecting plate 54, the slide plate 55 and the clamping plate 56 to gradually retract.

[0041] When the first retaining frame 41 descends to abut the first stop plate 111 in the lift compartment 11, the first motor 31 stops. Due to the U-shaped groove 372 on the lower side of the cargo cage 37, the second roller 373 at the bottom of the cargo cage 37 is able to pass through the gap between the first roller 21 in the horizontal conveying structure and sink to the bottom of the first roller 21. The clamping plate 56 is now fully retracted. As the distance between the first retaining frame 41 and the second retaining frame 42 increases, the U-shaped connecting plate 54 moves to the upper portion of the cargo cage 37 via the lifting chute 371. The chute plate 55 and the clamping plate 56 then move upward relative to the cargo cage 37. The chute plate 55, via the slider 572, drives the mounting plate 61 upward, and the push plate 67 also moves upward. At this point, the push plate 67, the chute plate 55, and the clamping plate 56 will not interfere with the entry of goods.

[0042] At this time, the goods are transported to the first roller 21 by the previous conveyor line, the first motor 31 reverses, the picking cage 37 rises, the first positioning frame 41 rises synchronously, and the distance between the first positioning frame 41 and the second positioning frame 42 is reduced. Since the first spring 47 is still in an extended state at this time, the second positioning frame 42 is still in contact with the second limit plate 112 under the tension of the first spring 47, and the push plate 67 and the clamping plate 56 maintain the same height as the second positioning frame 42. As the picking cage 37 and the goods rise, the push plate 67 and the clamping plate 56 enter the front and side of the goods respectively. Since the distance between the first positioning frame 41 and the second positioning frame 42 is reduced, gear 1 484 and the second gear 514 rotate in opposite directions, the U-shaped connecting plate 54, the slide plate 55 and the clamping plate 56 are pushed out, and the clamping plate 56 gradually approaches and abuts against the side of the goods to clamp the goods. Gear 1 484 and the second gear 514 stop rotating, and the distance between the first positioning frame 41 and the second positioning frame 42 remains constant. As the cargo cage continues to rise, the first positioning frame 41 and the second positioning frame 42 rise synchronously, and the cargo is lifted stably.

[0043] When the goods are lifted to the corresponding cargo warehouse height, the first motor 31 stops and the second motor 62 starts, and drives the push plate 67 fixedly connected to the second synchronous belt 66 to move toward the storage warehouse 12 through the driving shaft 63, the second synchronous pulley 65, the second synchronous belt 66 and the driven shaft 64, thereby driving the second slider 68 slidingly connected to the push plate 67 and the splint 56 fixedly connected to the second slider 68 to be pushed outward. The goods clamped by the splint 56 are synchronously pushed out to the corresponding cargo grid, and the second roller 373 at the bottom of the cargo cage 37 makes it easier to push the goods out.

[0044] After the cargo is fully ejected, the push plate 67 passes over the rectangular opening 551 on the chute plate 55 and abuts against the pressure rod 576 in the pop-up retraction assembly near one end of the storage bin 12. The pressure rod 576 compresses the third spring 578 and enters the interior of the slider 572. The second magnet 577 on the pressure rod 576 faces the first magnet 575 fixedly connected to the second guide post 573. The magnetic force attracts the first magnet 575 and the second guide post 574, and the chute plate 55 fixedly connected to the second guide post 573 retracts synchronously. The clamping plates 56 loosen to both sides, releasing the cargo. The second motor 62 rotates in reverse, driving the push plate 67 and clamping plates 56 to retract, and the cargo is transported to the storage bin 12. During the retraction process of the splint 56, the first magnet 575 and the second magnet 577 near one end of the storage bin 12 are always attracted, and the splint 56 is always in a retracted state. When the push plate 67 is fully retracted, the other end face of the push plate 67 abuts and compresses the pressure rod 576 in the pop-up retraction assembly away from the end of the storage bin 12, and the second magnet 577 away from the end of the storage bin 12 enters the interior of the slider with the pressure rod 576. The second magnet 577 at this end has opposite polarity to the first magnet 575, and the slide plate 55 and the splint 56 are pushed out, and the pressure rod 576 is extended again under the action of the third spring 578.

[0045] By providing a positioning lifting structure 4 and a lateral clamping structure 5, the present invention achieves unpowered switching of the clamping state for goods 7 at different heights, saving energy. To address the cumbersome and inefficient lifting and placing operations in existing line-side warehouses, the present invention provides a pop-up retraction assembly 57 that controls the retraction of the clamping plate to achieve rapid placement of goods, effectively improving work efficiency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
