A medium aggregation and separation device, comprising: a box body; the box body comprises at least two stacking parts and at least one reversing block; at least two stacking part channels are formed between an entrance of the box body and the stacking parts; the reversing block is disposed at the fork of the stacking part channels, the reversing block being a component that rotates about a fixed rotary shaft; when the reversing block rotates to a preset position, one stacking part channel is in communication while the remaining stacking part channel is closed such that a medium enters into a corresponding stacking part by means of the entrance of the boxy body and one stacking part channel. By means of dividing the box body into at least to stacking parts, the present invention may, according to the type of a medium, further convey the medium into a corresponding stacking part by means of the steering of the reversing block, and may increase the type of stacked media manifold such that one box body may be used for at least two media, thereby expanding the adaptability of existing machine core modules to medium type, and solving the technical problem wherein traditional financial tools cannot simultaneously support multiple currencies.
