Under the limit of the guide shaft, the rectangular push plate 49 moves horizontally.

[0028] In order to prevent the cargo on both sides from falling during the material collection process, the following features are also set: The anti-falling assembly includes a rotating shaft 25, and mounting holes are provided on the opposite inner walls of the square cavity. The rotating shaft 25 is installed in two mounting holes for rotation together. A flip gear 30 is fixedly sleeved on the rotating shaft 25. A mounting groove 28 is provided on the top of the vertical rack 24. A flip rack 29 is fixedly installed on the bottom inner wall of the mounting groove 28. The flip rack 29 is meshed and installed with the flip gear 30. Specifically, the number of teeth provided on the flip rack 29 is equal to one-fourth of the number of teeth provided on the flip gear 30.

The peripheral outer wall of the mounting shaft 33 is sleeved with a compression spring 34. When the vertical rack 24 moves, it drives the flip rack 29 to move synchronously, so that it can engage with the flip gear 30, thereby driving the rotating shaft 25 and the two flip plates 31 to rotate synchronously by ninety degrees, so that the two extrusion sleeves 32 and the two extrusion rods 35 rotate synchronously by ninety degrees, and the extrusion rods 35 are used to squeeze and limit the goods to prevent them from falling.

[0029] In order to switch between the pickup and inventory functions, the following features are also set: The switching assembly includes a mounting plate 55, which is fixedly sleeved on the outer wall of the circumference of the piston sleeve 56. An active cavity 36 is provided in the mounting plate 55. Two pin holes are provided at the top of the active cavity 36. Pins 37 are slidably installed in the two pin holes. Lifting blocks 39 are fixedly installed at the bottom ends of the two pins 37. Reset springs 38 are sleeved on the outer walls of the circumference of the two pins 37. An extrusion screw 42 is rotatably installed on the inner wall of the side of the active cavity 36. The other end of the extrusion screw 42 extends to the outside of the mounting plate 55 and is fixedly installed with a knob 40. Two ladder screws are threadedly installed on the extrusion screw 42. The two trapezoidal extrusion blocks 41 are respectively matched with the two lifting blocks 39. The side of the mounting plate 55 is provided with an avoidance hole, and the support shaft 13 is slidably installed in the avoidance hole. By arranging two pins 37 in the mounting plate 55, the two trapezoidal extrusion blocks 41 can squeeze one of the pins 37 when they move, so that it moves upward and engages with one of the pin grooves. Therefore, when the mounting plate 55 moves, only one of the first slider 17 and the second slider 26 will be driven to move, thereby realizing the switching of the picking or storage function, which is more convenient to use.

[0030] The working principle and use process of the present invention are as follows: when placing goods, place the goods on the top of the transport plate 9, rotate the knob 40 counterclockwise to drive the extrusion screw 42 to rotate, and drive the two trapezoidal extrusion blocks 41 to move synchronously in the direction of the knob 40 through the action of the thread, and squeeze one of the lifting blocks 39 to drive the pin 37 to move upward and insert it into the pin groove at the bottom of the first slider 17.

[0031] The two lifting motors 7 are started synchronously to drive the two lifting screw rods 8 to rotate synchronously. Through the action of the threads, the two lifting plates 5 are synchronously moved upward to a suitable position, so that the transport plate 9 is horizontally aligned with one of the upper plates 2. At this time, the transport plate 9 is clamped with the two clamping plates 43, and then the moving motor 10 drives the moving screw rod 11 to rotate, so that the slide plate 14 and the transport plate 9 can achieve horizontal movement. Through the clamping action of the two clamping plates 43, the L-shaped slide plate 59 is driven to achieve the synchronous movement function. When the transport plate 9 moves to the specified position, the solenoid valve 58 is closed. At this time, the slide plate 14 continues to move under the action of the thread, and the transport plate 9 remains stationary. The slide plate 14, the piston sleeve 56, and the mounting plate 55 move horizontally synchronously. The first slider 17 is driven to move horizontally through the engagement of the pin 37 with the pin groove. When the first slider 17 moves horizontally, the transverse rack 19 is driven to move synchronously. Through the meshing action of the transverse rack 19 and the transverse gear 20, the conveying screw 16 is driven to rotate synchronously, so that the square slider 21 and the first push plate 22 move horizontally synchronously, and the goods are pushed from the top of the transport plate 9 to the top of the upper placement plate 2, thereby realizing the function of placing goods.

[0032] When taking down the goods, by turning the knob 40 clockwise, one of the pins 37 is driven to engage with the pin groove at the bottom of the second slider 26, and the above steps are repeated to make the transport plate 9 and the L-shaped slide plate 59 move synchronously to a suitable position. When the transport plate 9 remains stationary, the slide plate 14 drives the mounting plate 55 and the second slider 26 to move, thereby driving the vertical rack 24 to realize the movement function under the action of the connecting rod 27. When the vertical rack 24 moves, it drives the flip rack 29 to move synchronously. Through the meshing action of the flip gear 30, the rotating shaft 25, the two flip plates 31, and the two squeezing rods 35 are synchronously flipped 90 degrees to squeeze the goods on both sides of the goods to be taken to prevent them from falling. In the squeezing process, the squeezing rod 35 can automatically adapt to the size of the goods through its telescopic function in the squeezing sleeve 32, and squeeze goods of different sizes, thereby improving safety performance. When the vertical rack 24 enters the L-shaped cavity along the insertion hole, it drives the circular shaft 44 and the large sprocket 46 to rotate through the meshing action with the vertical gear 45. The meshing of the large sprocket 46, the small sprocket 51 and the chain 47 accelerates the rotation of the rotating rod 50, and under the meshing action of the active bevel gear 52 and the driven bevel gear 53, the screw guide sleeve 48 is rotated, thereby driving the screw 54 and the rectangular push plate 49 to move horizontally under the action of the guide shaft, pushing the goods to the top of the transport plate 9, and in the pushing process, the two flip plates 31 can be used to limit the position to prevent the goods from falling.
