Detailed ways

Further description will be made below in conjunction with drawings and embodiments.

Embodiment 1: An infrared weighing machine for banknote change, controller and display screen 2, stepping motor one 5, stepping motor two 6, banknote identification device 1, electronic scale 7 are electrically connected; The shape of the device is a groove, and the side wall of the groove slightly tightens the coin so that the coin will not fall naturally on the groove. The middle part of the coin output device is a transmission belt 4, and the stepping motor drives the transmission belt to move; one end of the coin output device is adjacent to The transmission belt opens the leaking coin hole 10, and the electronic scale is below the coin output device. A slide rail is arranged between the coin leaking hole and the electronic scale, and there is a gap in the middle of the slide rail. Axis turns left and right, and the lower left side of the electronic claim is the waste coin slot 13, and the lower right side of the electronic claim is the coin output slot 8. An infrared emitter 12 and an infrared receiver 11 opposite to each other are arranged on both sides of the coin leaking hole under the coin dispensing device, and the infrared emitter and the infrared receiver are respectively electrically connected to the controller.

The banknote changing machine is powered by dry batteries, rechargeable batteries or low-voltage DC power supply. The machine can be installed at bus stops, transportation hubs or crowd gathering places. At this time, dry batteries and rechargeable batteries are used for power supply; the machine can also be installed with buses and used by cars. DC low voltage power supply inside.

The banknote identification device is a small denomination banknote identification device used in ordinary vending machines, which can identify 1 yuan, 5 yuan, 10 yuan, and 20 yuan banknotes. The controller is a general-purpose programmable chip. According to the thickness of the coin, the machine sets the displacement of a coin on the conveyor belt in advance and saves it as the initial value. When the user feeds the banknote into the banknote recognition device, the machine recognizes its denomination. The system is only set to recognize coins with denominations of 5, 10, and 20) The display screen displays relevant prompt information, and the relevant operations are completed by touching the display screen. When exchanging coins of the same value, the controller obtains the amount information of the banknotes, multiplies the initial value set in advance by the denomination of the banknotes to obtain the actual displacement that needs to be moved, and further sends a command to the stepping motor 1 to control its rotation to move the coins at a corresponding angle.

The coin moves on the conveyor belt, passes through the coin hole, and passes through the slide rail between the coin hole and the electronic scale, and the coin slides onto the electronic scale. There is a gap in the middle of the slide rail, and the infrared transmitter 12 and the infrared receiver 11 are installed therein. During this time, the infrared ray counts the falling coins through the gap in the middle of the slide rail, and feeds back to the controller.

The coin is weighed by an electronic scale after it falls. There are two kinds of one-yuan coins in circulation. The weight of the peony one-yuan coin is 6.05 grams, and the weight of the chrysanthemum one-yuan coin is 6.1 grams. Set a reasonable error space. In this example, take the 5-yuan coin as an example. The minimum value of the theoretical quality is 30.25 and the maximum value is 30.5, and the range is set between 28-32. The value of the electronic scale is within this range, and the infrared count is 5, it is considered to be 5 coins, the controller starts the stepper motor 2 to drive the electronic scale to rotate to the right, the coin falls into the coin slot, and the operation is completed; the value of the electronic scale is not above the above Interval, when the infrared count is not 5 at the same time, error handling is performed: if the two errors are consistent, for example, the infrared count is 4, and the electronic weighing is 24 grams (22-26 interval, 4 coin range) determined as 4 coin control The device starts the stepper motor to transmit the distance of a coin thickness, and fills in a coin to complete the exchange.

If the infrared counting is inconsistent with the counting of the electronic scale, it is considered that the processing is wrong, and the controller reversely starts the stepper motor 2 to drive the electronic scale to rotate to the left, the coin falls into the waste coin slot, and the coin exchange operation is restarted.

There are baffles around the electronic scale, and the front and rear baffles are fixed, (the front and rear baffles can also be acted by the shell of the machine itself, so that the distance between the electronic scale and the shell is less than the thickness of a coin), the left and right baffles are connected by springs and can be turned outwards . The structure of the optical drive out box in the computer case can be adopted, and the coin slides down to make it open due to its own gravity, and it will be closed automatically when there are no coins; it can also be reversed to fix the lower opening.

The whole banknote exchange machine also includes a coin storage box 9. The coin storage box is composed of multiple sets of partitions to form an independent space and tilts towards the direction of the coin output device. The capacity of each space is equal to the capacity of the coin output device. The partitions can be lifted separately. The coin storage box and the coin output device are connected by an inclined plane. When the coins in the coin output device are empty, the coin storage box can transport the stored coins to the coin output device: the bottom partition of the coin output device is opened, and because the coin storage box is inclined, the coins slide down to the coin output device through the slope as a whole. Then, the lowermost dividing plate is closed, and the upper level dividing plate is opened successively, and the coins in multiple groups of spaces in the coin storage box move down one space successively. Each set of space in the coin storage box has an elastic tightening device to ensure that the coins are close to each other and vertical. Until all coins are exchanged, the display screen prompts the user to process.
