When each pair of bills is printed, the number wheel rotates to reduce the number of the bills by one.

After the number printer prints the bill, the conveyer belt will drive the bill to move towards the export until the bill falls into the bill. Before cutting the bill and ordering, need sort the branch pile according to appointed page number with the bill earlier, but because the bill pile has several hundreds of thousands bills usually, the manual work is checked one by one in the bill pile and is very inconvenient.

Disclosure of Invention

The invention aims to provide a bill inserting device which has the advantage of improving the efficiency of manually sorting bill piles.

The technical purpose of the invention is realized by the following technical scheme:

a bill inserting device comprises a number printer, wherein the number printer comprises a number wheel for printing bills, and the side surface of the number wheel is provided with a clamping block and a shading wheel arranged on the clamping block; a plurality of light through holes corresponding to the numbers are formed in the side face of each number wheel in a penetrating mode, the light through holes are equidistant to the axis of the number wheel and are uniformly arranged around the axis of the number wheel, and a plurality of light aligning holes used for being communicated with the light through holes and light blocking blocks detachably mounted in the light aligning holes are formed in the side face of each light blocking wheel in a penetrating mode;

the number printer is characterized by further comprising a photoelectric sensor, wherein the photoelectric sensor comprises a transmitting end and a receiving end which are respectively arranged on two sides of the number printer, an extension part of a detection light beam emitted by the transmitting end in the propagation direction is an optical channel, the distance from the optical channel to the axis of the number wheel is matched with the distance from the light through hole to the axis of the number wheel, the transmitting end transmits detection light to the receiving end through the optical channel, the number printer is connected or disconnected through rotating the number wheel, and the photoelectric sensor outputs a photoelectric detection signal based on the connection or disconnection of the optical channel;

the control module is electrically connected with the photoelectric sensor and outputs a label inserting control signal based on the photoelectric detection signal;

the note stack mark inserting device comprises a note stack, and is characterized by further comprising an execution module, wherein the execution module comprises a mark inserting machine, and the execution module controls the mark inserting machine to insert marks into the note stack based on a mark inserting control signal.

By adopting the technical scheme, when the number printer is used, every time the number printer passes through one bill, the number on the number printer will retreat by 1, the number will carry when the number printer is full of 10, and the like, the corresponding number wheel will rotate and drive the shading wheel to rotate together. Because the light aligning holes on the shading wheel and the light through holes on the number wheel are correspondingly arranged, the number wheel can be displaced together when rotating. The shading wheels are arranged side by side, and part of the shading wheels are provided with light blocking blocks, so whether the light channel is communicated or not is determined by the arrangement condition of the light blocking blocks on the shading wheels and the rotation of the shading wheels.

When the light blocking block is positioned on the light channel, the light channel is disconnected; when each number wheel has a light through hole positioned on the light channel and no light blocking block is arranged in the light through hole positioned on the light channel, the light channels are communicated, and the receiving end of the photoelectric sensor receives the detection light beam emitted by the emitting end and outputs a corresponding photoelectric detection signal. The control module outputs a label inserting control signal based on the photoelectric detection signal to control the label inserting machine to insert labels into the bill pile.

Different gobo wheels will correspond to different frequencies of light channel communication. For example, when fifty bills are required to be used as an interval output label insertion control signal, the light shielding wheel corresponding to the hundreds digit and the higher digits is not provided with the light shielding block, the light shielding wheel corresponding to the tens digit is provided with eight light shielding blocks, two light focusing holes without the light shielding blocks on the light shielding wheel are positioned on the same diameter of the light shielding wheel, and the light shielding wheel corresponding to the units digit is not provided with the light shielding block.

Therefore, the device can insert the mark to the bill pile of production as required, improves the efficiency that people sorted the bill pile.
