[0056] Embodiment 2:

[0057] like Figure 6 As shown, the difference between this embodiment and the vertical warehouse conveying and weighing device provided in Embodiment 1 is that two material level openings are provided, and the feed conveying line 41 extends to the material level opening away from the weighing platform 5, and the conveying mechanism 4 also includes a second lifting conveying line 44 that is slidably connected to the bracket along the Z-axis direction and can receive the waiting position conveying line 43 and convey along the X-axis direction, and a discharge conveying line 45 that is provided at the second lifting conveying line 44 along the Y-axis direction and can convey the powder box to the material level opening, and the second lifting conveying line 44 is located at the weighing end.

[0058] The unloading end of the discharging conveying line 45 is also provided with a discharging limiting plate 47 capable of abutting against the side wall of the powder box and limiting guide plates 46 arranged on both sides of the discharging conveying line 45 .

[0060] When in use, the worker inputs the recipe through the human-machine interface 51, and the system automatically grabs the powder box required on the recipe, and transports it to the second lifting conveyor line 44 via the U-shaped conveyor line for weighing. According to the required weight on the recipe, choose to use a large scale or a small scale to weigh the material.

[0061] The stacker 1 is responsible for taking out the powder boxes on the shelf 3 and conveying them to the feeding conveyor line 41. At this time, the feeding conveyor line is started to convey the powder boxes to the position of the lifting conveyor line. Through the lifting function of the lifting conveyor line, the powder boxes are lifted to the same position as the waiting conveyor line. Then the lifting conveyor line and the waiting conveyor line are started to transport the powder boxes to the waiting conveyor line. At this time, if the powder boxes are weighed at the second lifting conveyor line 44, the second lifting conveyor line 44 is raised, and the waiting conveyor line 43 and the second lifting conveyor line 44 are started to convey the powder boxes to the second lifting conveyor line 44. At this time, the second lifting conveyor line 44 descends, and the workers weigh the powder. After the weighing is completed, the discharging conveyor line 45 is started to convey the powder boxes to the discharging limit plate 47 and stop. At this time, the stacker 1 takes out the powder boxes and puts them into the corresponding shelf 3.

[0062] To sum up, the utility model can convey the powder boxes that need to be weighed to the material level port through the stacker 1, and then receive the powder boxes at the material level port through the conveying mechanism 4, so that the powder boxes are arranged one by one on the conveying mechanism 4, and conveyed to the weighing platform 5, thereby realizing automatic transportation of the powder boxes, eliminating the need for manual long-distance transportation, thereby improving the weighing efficiency of the powder boxes, and can reduce manpower, making weighing more convenient.
