Considering that sometimes passengers may insert multiple banknotes or multiple coins at a time to cause congestion, at least one roller is connected with a compression spring. If there is a lot of money, the two rollers can slide to the two sides and move separately. The two rollers return to their original positions under the action of the compressed spring. After the coin insertion is over, if no input signal is detected within 10 seconds, the control system sends a signal to stop the operation of the motor.

2. The present invention is provided with a sorting mechanism for separating banknotes and coins. The mechanism is equipped with thimbles at the lower end of the coin slot. The minimum horizontal distance between the thimbles is greater than the diameter of a one-yuan coin and less than the width of a dime banknote, so the coins fall The coins will fall into the coin storage area below; since the minimum horizontal distance between the thimbles is less than the width of a dime banknote, the banknotes will slide along the downward slope of the free ends of the thimbles into the banknote pre-storage box below to realize the storage of banknotes. Keep it separate from coins.

3. When the coin insertion is over, the cam under the banknote pre-storage box rotates, making the banknote storage box vibrate around the hinge connected with the nut, and the banknotes are aligned along the baffle. After a period of time after no one inserts coins and the car starts, the system starts to prepare to sort the banknotes in the banknote pre-storage box into the corresponding banknote boxes, and the upper banknote validator starts to detect the denomination of the top banknote, and then the controller controls The banknote pre-storage box moves to the corresponding position along the screw, and then the banknote sorter dials the topmost banknote into the corresponding box. And the system accumulates the currency value, and the overall data can be called out through the query button on the control panel, and displayed on the liquid crystal display.

4. After the money is released, the rotation of cam Ⅰ and cam Ⅲ drives the movement of the coin storage cylinder so that the banknotes in the currency storage cylinder are arranged neatly along the direction of the banknote roll, which is convenient for change later.

5. If the passenger clicks the change button module, the banknote detection device will send the face value of the banknote to the control system, and the control system will start the dial mechanism on the top of the corresponding coin storage cylinder according to the banknotes that need to be changed, and the motor on the top will drive the dial The mechanism lowers, and at the same time pushes the cam Ⅰ close to the banknote roll to rotate an angle, so that the banknote storage tube is raised by an angle to facilitate the coin output, and the rubber wheel rotates an angle, and a banknote is sent into the banknote roll and sent out to the exit.
