The basic composition of

The banknote machine consists of six parts, such as twirling, issuing, receiving, rack and electronic circuit.

Twist notes section

It is mainly composed of the slip board, the banknote, the resistance eraser, the drop board, the adjusting screw, the twister ring, etc. Will be

It is the premise of ensuring the counting accurately that the counting of banknotes is turned out. The machine USES face out of the bank note for grading: twist chao aprons walk twist in the surface of a dollar bill, the bill was resistance rubber sticks, make money is separated from the bill, on the surface of the say good bye. This process is repeated until the last note is finished.

Due to the change of the problem, the rubber ring and the friction of the friction rubber have been the two major problems that have perplexed people. To solve this problem, it is: 1. 2. Convenient replacement. To twist chao aprons, we can use increased diameter, outer circle in the middle a ring groove, to raise the wearability of twisting chao aprons, and the aprons to the cross section axial sawtooth instead, make the contact area of tooth surfaces of synthetic relative notes, improve the adhesion of the tooth face of synthetic notes. For the attached drawing eraser, the simple method is to use the resistance rubber to change the structure, and the back end of the slide plate can be easily removed.

The money part

It mainly consists of the issuing rubber wheel and the turning wheel. Its effect is out of money aprons to twist chao aprons twice the linear velocity of money sent straight to the first with the back of the bill effectively separated, sent to the counter with the sensor to count and scrutiny.

Note: the money leaves the ring and enters the ring. TD series paper money machine due to twist shaft lift distance between shaft and the bill (60 mm) are less than the width of the counting money (maximum 77 mm), the remaining width of money can lead to twist chao aprons and the relative friction between money, reduce the twist notes the service life of aprons. It is possible to avoid the occurrence of friction by widening the distance between the bill and the axis of the twister (the distance between the axis of the banknote and the axis of the twister is 80mm). Due to twist chao axis and the distance between the axis widened the bill, in order to ensure smooth movement of money from the twisting chao to round out the money, add a right wheel, a wheel linear velocity is equal to the twist of the outside of the linear velocity of the outside of the chao aprons, the linear velocity of the outside of the chao aprons is double that of outer twisting chao aprons and linear velocity. When the outer chao aprons and twist to the money, money that is twice the original speed movement, so that it will twist chao wear aprons transferred to the wheel, and the wheel adopts wear-resisting material, junior high school has been proved that twist notes the service life of aprons improved several times.

Although adding a pair of wheels can improve the service life of the twister ring, the problem is that the cost increases, the structure is complex, and the maintenance is inconvenient. If without any increase in the right wheel, and use the twist of chao an overrunning clutch shaft jacket (commonly known as a one-way bearing), can have the same effect, principle is as follows: one-way bearing is installed within the twisting money driving wheel, can relative to twist money turn counter-clockwise. Twist twist chao, chao driving wheel clockwise, one-way bearing rotation, transfer dynamic role, when the money to go to a bank note lugs, namely movement at twice the original speed, under the drag of money, as a result of the action of the one-way bearing, twist chao aprons rim with the same speed and money, money, and there is no relative sliding between twisting chao aprons, and thus can prolong the service life of twisting chao aprons.

Pick up money part

It is mainly composed of the bill claw wheel, the withdrawal board, the bankroll and so on. After the inspection, the bills are drawn into the different claws of the claw wheel, and the banknotes are removed and stacked neatly. The phenomenon of flying banknotes is more common in the counting machine. To solve this problem, it is necessary to pay attention to three aspects: first, the center position of the impeller, the shape of the blade claw, and the rotation speed of the impeller.

(1) determining the chao impeller center position: the chao impeller center should be close to the chao axis, as far as possible when the money leave the chao aprons, must try to card into the claws of the deep, so it can guarantee money from flying money because of the card into the light.

(2) the shape of the blade's claw: the curve should be inserted into a bending deformation after the banknote is inserted, and the larger the deformation of the banknote, the more difficult it will be to get out.

(3) impeller speed: the faster the impeller speed is, the more likely it is to fly, but too slow the bill will hit the bottom of the blade. The impeller speed is related to the speed of counting and the number of leaves.

The transmission part

The transmission part can be driven by a single motor or a dual motor. The motor is transmitted to each transmission shaft through the transmission belt and the transmission wheel. Dual motor drive is easy to realize preset function. The motor can be used ac or dc motor, because of the importance of the motor and transformer, such as the use of dc motor with switching power supply, it can greatly reduce the weight of the whole machine.

Rack components

It is proved by practice that the effect of edge plate is better. Using this kind of design has the advantage of the left and the right of frame corresponding to the high precision part can use the same mold finish in one time and improve the assembly precision of the machine frame, reduces the cost, also provides the movement of money to effectively identify the required location accuracy.

Electronic circuit

A master control part, sensor part, flooding chy-tech pieces, power panel consists of a single-chip microcomputer control system, such as purple light through multiple interfaces, magnetic, infrared transmission, counting signal is introduced into the host controller. Statistical sampling, identification and storage of the normal banknotes in the normal inventory of the signals received by each sensor are used as the basis for testing. When counting the notes, the received signal in each channel interface parameters comparing with the original signal parameters of registering, judgment, if there are significant differences, but immediately send out alarm signal and stop the motor, send the corresponding signals at the same time.
