The ATM cash-out module is generally composed of upper and lower two-layer functional modules: the upper layer is a banknote inspection, banknote delivery and waste bank recovery module; the lower layer is a banknote box and a banknote diversion module (composed of 1 to 4 identical banknote recovery units) .
The function of the banknote inspection and banknote delivery module is to detect the height, thickness and inclination of each banknote dug out by the banknote supply module, and control the sorter to send the banknotes that are not qualified to the banknote reject box, and the banknotes are qualified banknotes. Then it is sent to the stacker. Finally, the banknote transfer robot sends the banknotes to the banknote outlet to complete the banknote dispensing operation. If the customer does not withdraw the funds over time, the banknotes are taken back into the banknote return box.
The role of the banknote digging module is to place the cashboxes and dig out the banknotes one by one from the cashboxes according to the instructions. There are two ways to dig the banknotes: vacuum sucking money and rubbing out of the banknotes. Both methods have their own merits, vacuum suction is accurate and reliable, easy to maintain, but the cash out speed is slow (1~2 sheets/second), only NCR company is currently used, and the advantage of friction and banknote dispensing technology is that it is fast (5 ~7 frames per second, used by most ATM vendors.
