Abstract

The invention discloses a banknote sorting machine. Existing banknote sorting and statistical work are basically completed manually. The invention includes a banknote temporary storage mechanism, a banknote separation mechanism, a banknote stretching and identification mechanism, a banknote collection and sorting mechanism, and a peripheral support; the banknotes to be separated are put into the banknote temporary storage mechanism, and enter the banknote stretching and recognition mechanism one by one through the banknote separation mechanism. The upper and lower rows of nylon rollers with constant rotation speed can distinguish the denomination of banknotes by using the different lengths of banknotes of different denominations and the different shading time when they pass through the photoelectric sensor; The banknotes are stretched at different speeds; banknotes of different denominations are output by the banknote stretching and identification mechanism into the corresponding collection boxes of the collection and sorting mechanism. The invention can realize the sorting and sorting of a large number of banknotes of different denominations.

The operation principle of the paper currency sorter：

The first step, bottom baffle 1-2 and paper money temporary case 1-1 is in and fits closely state when paper currency sorter starts, will Multiple bank note are put into simultaneously in paper money temporary case 1-1, and electric rotating machine 1-3 starts automatically after a period of time, control cabinet bottom baffle 1-2 It is rotated down until being bonded with the upper surfaces V-type groove baffle 2-1.

Second step, driving motor 2-6 drive twist wheel 2-2, brush wheel 2-3 to rotate by belt transmission, and twist wheel 2-2 and V-type are recessed Multiple bank note are twisted by the sizeable groove cooperation in the upper surfaces slot baffle 2-1 one by one, before being transported to brush wheel.Brush wheel 2-3 and hinge Bank note is input to the two rows of bank note stretching, extension and identification mechanism 3 by two driven auxiliary wheel cooperations being connected on horizontal supporting plate 2-7 Between nylon roller 3-1.

Third walks, and starts driving motor 3-6 and drives driving gear 3-5 and two driven gear 3-7 rotations, and then by same It walks belt wheel 3-3 and synchronous belt 3-4 drives two rows nylon roller 3-1 to relatively rotate.Nylon roller is carried out in preliminary installation Horizontal adjustment ensures to shift because of the grinding pressure difference of width direction after bank note enters nylon roller 3-1.Bank note It is clipped between nylon roller 3-1 and continues to transmit, the synchronous pulley diameter of input terminal is more than the synchronous pulley of output end, two before institute Speed discrepancy is had between nylon roller 3-1 and rear three pairs of nylon rollers 3-1, rear three pairs of nylon roller relative velocity is very fast, institute With bank note by when have larger stretching action, bank note is in the state of full extension.It is installed on to penetrating photoelectric sensor 3-2 Second pair and third between nylon roller 3-1, when bank note is by penetrating photoelectric sensor 3-2 in extended configuration and speed it is permanent Fixed, then the length of paper currency difference of different denominations causes to experience the different shading time to penetrating photoelectric sensor；Because nylon rolls Adjustment is had already passed through before cylinder, so bank note will not shift, thus the time that is blocked of photoelectric sensor is accurate paper Coin long side by time rather than the time of catercorner length, ensure the accuracy of identification；It will be blocked to penetrating photoelectric sensor Time signal feedback is handled in control system.

4th step, control system control corresponding collection motor 4-3 according to the time signal that is blocked and rotate forward certain angle, from And the collecting board 4-4 of different length is driven to rotate up, so that the bank note of different denominations is transported out from two rows of nylon roller 3-1 It drops on the collecting board of corresponding length, to slide into different collecting boxs.Then control system sends out reversion letter in time Number, the motor reversal for just having had rotating forward to act restPoses.After all bank note have all been collected, power supply, electric rotating machine are closed 1-3 drives bottom baffle 1-2 to reset to original state.
