[0024] A buffer bin inside a nitrogen bin, comprising a box body 1, at least two induction doors 2, at least two induction door driving components 3, and a roller conveyor line 4. Through openings 10 are provided on both the front side and the rear side of the box body 1.
[0025] The roller conveyor line 4 enters from the through opening 10 on the front side of the box body 1, passes through the inside of the box body 1, and exits from the through opening 10 on the rear side of the box body 1. The roller conveyor line 4 is arranged in the front-rear direction. The two induction doors 2 are respectively arranged to be movable up and down at their respective through openings 10. The two induction door driving components 3 are respectively arranged on the front side and the rear side of the box body 1, and both of the two induction door driving components 3 are used to drive the induction doors 2 to move up and down.
[0026] In the present solution, there are two such buffer bins inside the nitrogen bin, which are respectively arranged in the incoming goods area and the outgoing goods area inside the nitrogen bin. In this embodiment, taking the buffer bin arranged in the incoming goods area inside the nitrogen bin as an example, as Figure 1As shown in the figure, there are two induction doors 2 and two induction door drive assemblies 3. The currency inlet 10 on the front side of the box body 1 serves as the inlet for the nitrogen storage. In the initial state, the induction doors 2 corresponding to the currency inlet 10 on the front side of the box body 1 and the induction doors 2 corresponding to the currency inlet 10 on the rear side of the box body 1 are both in the closed state. When goods need to enter the interior of the nitrogen storage, the staff first place the goods on the roller conveyor line 4. Under the action of the roller conveyor line 4, the goods are transported to the currency inlet 10 on the front side of the box body 1. At this time, the induction door drive assembly 3 arranged on the front side of the box body 1 drives the corresponding induction door 2 to move upward to an open state. The goods can be transported into the interior of the box body 1 under the action of the roller conveyor line 4. During the process of the goods entering the interior of the box body 1, since the induction door 2 corresponding to the currency inlet 10 on the rear side of the box body 1 is in the closed state, the nitrogen in the nitrogen storage cannot leak into the external environment, and the humidity in the external environment cannot enter the nitrogen storage either. When the goods are transported to the currency inlet 10 on the rear side of the box body 1 under the action of the roller conveyor line 4, at this time, the induction door drive assembly 3 arranged on the front side of the box body 1 drives the corresponding induction door 2 to move downward to a closed state, and the induction door drive assembly 3 arranged on the rear side of the box body 1 drives the corresponding induction door 2 to move upward to an open state. The goods can be transported into the interior of the nitrogen storage under the action of the roller conveyor line 4, which is beneficial to subsequent storage tasks. During the process of the goods entering the interior of the nitrogen storage, since the induction door 2 corresponding to the currency inlet 10 on the front side of the box body 1 is in the closed state, the nitrogen in the nitrogen storage cannot leak into the external environment, and the humidity in the external environment cannot enter the nitrogen storage either.
[0027] In this solution, a buffer bin is arranged in the nitrogen storage, and automatic lifting induction doors 2 are arranged at the currency inlets 10 on the front side and the rear side of the box body 1 of the buffer bin. When goods need to pass through the currency inlet 10 on the front side of the box body 1, the induction door 2 corresponding to the currency inlet 10 on the front side of the box body 1 opens, and the induction door 2 corresponding to the currency inlet 10 on the rear side of the box body 1 closes; when goods need to pass through the currency inlet 10 on the rear side of the box body 1, the induction door 2 corresponding to the currency inlet 10 on the front side of the box body 1 closes, and the induction door 2 corresponding to the currency inlet 10 on the rear side of the box body 1 opens. In this way, it can be ensured that the nitrogen in the nitrogen storage will not leak into the external environment, reducing the loss of nitrogen. At the same time, the humidity in the external environment cannot enter the nitrogen storage, affecting the storage conditions of the items in the bin.
