Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, a schematic structural diagram of a banknote sorting mechanism according to an embodiment of the present invention is shown, which is detailed as follows:
at present, most of automatic cash equipment comprises a cash distribution mechanism, the cash distribution mechanism generally comprises a cash distribution wheel 1 and a separation wheel 2 which are arranged in a pair of rollers, a pair of roller gap is formed between the cash distribution wheel 1 and the separation wheel 2, and the cash distribution wheel 1 and the separation wheel 2 can rotate in opposite directions under the drive of a motor so as to convey the paper money entering the pair of roller gap to a preset cash outlet direction.
In the embodiment of the invention, the separating wheel 2 adopts a torsion limiter which is used for preventing the paper money contacting with the torsion limiter in the double-roller gap of the paper money separating wheel 1 and the torsion limiter (the separating wheel 2) from moving to the appointed paper money outputting direction when the paper money is the double-roller gap paper money.
Specifically, when the paper money entering the double-roller gap is the double-piece paper money, the double-roller gap is fixed, and the thickness of the double-piece paper money is larger than that of a single paper money, so that the pressure of the paper money separating wheel and the torsion limiter on the double-piece paper money in the double-roller gap is increased, and correspondingly, the rolling friction force between the paper money contacting with the torsion limiter in the double-piece paper money in the double-roller gap and the torsion limiter is also increased; by selecting a suitable torsion limiter such that the rolling friction is greater than the torsion limit of the torsion limiter, the torsion limiter in this case prevents the banknotes coming into contact with the torsion limiter from moving in the intended dispensing direction in a slipping manner (stop or reverse rotation).
It should be noted that a torque limiter, also called a torque limiter, can provide overload protection; the torque limiter limits the torque (or torque) transmitted by the transmission system in a slip fashion when it is overloaded, i.e. when it is applied with a torque (or torque) that exceeds its limit torque (or torque).
In addition, the limiting torque value of the torque limiter is an inherent parameter, and the limiting torque of the torque limiter is equal to the rated torque of the torque limiter divided by the vertical distance from the rotation axis of the torque limiter to the contact surface of the torque limiter and the paper money; in the embodiment of the invention, the torsion limiter with proper parameters is selected and used as the separating wheel in the banknote separating mechanism, when the double-roller gap enters the double-roller banknote, the banknote contacting with the torsion limiter is prevented from moving, and only the banknote contacting with the banknote separating wheel moves towards the banknote outlet direction, so that the separation of the double-roller gap entering the double-roller gap is realized. When the paper money in the double-roller gap is single paper money after the paper money in the double-piece paper money contacted with the paper money separating wheel is sent out of the double-roller gap, the pressure between the paper money separating wheel and the torsion limiter is reduced, the rolling friction force between the paper money and the torsion limiter is correspondingly reduced, the torsion limiter restores to a normal working state and synchronously rotates opposite to the paper money separating wheel, and the single paper money in the double-roller gap is conveyed towards the paper money outlet direction.
In addition, in the embodiment of the present invention, the torsion limiter is used as the separating wheel in the banknote separating mechanism, other parts may not be changed, and the specific fixing manner and connection relationship of the torsion limiter may refer to the fixing and connection relationship between the banknote separating wheel and the separating wheel in the prior art, which is not described herein again.
As a preferred embodiment, the torque limiter of the present invention is specifically described as follows: referring to fig. 2, a schematic structural diagram of a torque limiter provided by an embodiment of the present invention is shown, where the torque limiter includes an inner rotating body 21 and an outer rotating body 22;
the inner rotor 21 is used to output a rated torque to the outer rotor 22;
the outer rotating body 22 is used for rotating in the same direction as the inner rotating body 21 when the torque applied to the outer rotating body 22 by the paper money contacted with the torque limiter is not more than the rated torque; and, when the torque applied to the outer rotating body 22 by the paper money contacting the torque limiter is greater than the rated torque, the paper money rotates in opposite direction to the inner rotating body 21.
In the embodiment of the invention, the outer rotor 22 and the inner rotor 21 are coaxially arranged, the outer rotor 22 and the banknote separating wheel are arranged in a pair roller way, when the banknote separating wheel works, the motor drives the banknote separating wheel and the inner rotor 21 to rotate oppositely, and the inner rotor 21 outputs rated torque to the outer rotor 22; when the paper money fed into the gap between the double rollers is single paper money, the outer rotating body also rotates oppositely to the paper money separating wheel under the action of the rated torque, so that the single paper money in the gap between the double rollers is conveyed towards the paper money outputting direction; when the paper money fed into the double-roller gap is the overlapped paper money, the pressure in the double-roller gap is increased, the torque applied to the outer rotating body by the paper money is increased, so that the outer rotating body stops rotating or rotates reversely (rotates in the same direction as the paper money separating wheel), and the paper money in the double-roller gap and contacted with the outer rotating body is prevented from moving towards the paper money outputting direction.
As a further example, the torque limiter is a magnetic torque limiter, as shown in fig. 2, the outer rotor 22 includes a magnetic plate 220, the inner rotor 21 includes a magnet 210, and when the torque applied to the outer rotor 22 by the bills contacting the torque limiter is greater than the rated torque, the outer rotor 22 and the inner rotor 21 rotate in opposite directions under hysteresis.
In the embodiment of the present invention, when the magnetic plate 220 and the magnet 210 rotate relative to each other (when a double note enters the gap between the pair rollers), a torque is generated by the hysteresis (phase difference) of the magnetic plate, using the hysteresis of the magnetic plate 220 (for example, a magnetic coil) and the magnetic force of the magnet 210 (for example, a permanent magnet with multiple poles). The torque generated in this embodiment is a non-contact torque, and the torque generating portion is not damaged, so that the stability and durability are good, and the magnitude of the generated torque is determined by the magnetic field characteristics of the magnetic plate 220.
To further illustrate the operation of the torque limiter in the embodiments of the present invention, the following detailed description is provided with reference to fig. 3-a and 3-b:
referring to fig. 3-a, which shows an operation schematic diagram of the banknote sorting mechanism provided in the embodiment of the present invention, for explaining operation states of the banknote sorting wheel and the torsion limiter when the banknote entering the double-roller gap is a single banknote, as shown in the figure, the banknote 41 enters the double-roller gap formed by the banknote sorting wheel 1 and the torsion limiter 2, the banknote sorting wheel 1 and the torsion limiter 2 rotate in opposite directions under the driving of the motor, wherein the inner rotor 21 and the outer rotor 22 of the torsion limiter rotate coaxially and in the same direction, and the banknote moves to the banknote output direction through the double-roller gap.
Referring to fig. 3-b, another operation diagram of the banknote sorting mechanism according to the embodiment of the invention is shown, which illustrates the operation states of the banknote sorting wheel and the torque limiter when the banknote entering the gap between the two rollers is a double-banknote, as shown in the figure, the banknote 41 and the banknote 42 form a double-banknote and enter the gap between the two rollers, at this time, due to the increase of the pressure in the gap between the two rollers, the torque applied to the outer rotor 22 of the torque limiter by the banknote 42 increases, and the torque is greater than the limited torque of the torque limiter, the outer rotor 22 and the inner rotor 21 rotate relatively, the magnetic plate of the outer rotor 22 generates a torque due to hysteresis, the outer rotor 22 and the banknote sorting wheel rotate in the same direction (the outer rotor 22 and the inner rotor 21 rotate in opposite directions), and the banknote 42 is prevented from moving in the banknote dispensing direction. The paper money 41 is conveyed to the paper money outlet direction under the action of the paper money separating wheel, after the paper money 41 is conveyed out of the double-roller gap, a single paper money 42 is remained in the double-roller gap, the pressure in the double-roller gap is reduced, the torsion force applied to the outer rotating body 22 of the torsion limiter by the paper money 42 is reduced, the torsion force is not more than the limited torsion force of the torsion limiter, and the torsion limiter restores the working state of processing the single paper money.
As an optional embodiment, the torque limiter may also be a spring-type torque limiter, which can further reduce the cost.
As a preferred embodiment, the coefficient of friction μ between the outer rotor 22 and the banknote in contact therewith satisfies the following relationship:
μ1>μ>μ2
wherein, mu1Indicating the coefficient of friction, mu, between the separating wheel and the bank notes in contact therewith2Indicating the coefficient of friction between the notes of a double note.
In the embodiment of the invention, the rubber sleeve can be arranged on the outer side of the torsion limiter, and the friction coefficient between the rubber sleeve and the paper money is larger than that between two pieces of paper money of the overlapped paper money and smaller than that between the paper money separating wheel and the paper money, so that the overlapped paper money can be separated in a sliding manner.
As a preferred embodiment, the rated torque T of the torque limiter satisfies the following formula:
N*μ1>T/L>N*μ2
wherein N represents the pressure between the banknote separating wheel and the torsion limiter, L represents the rotation of the torsion limiterDistance (perpendicular distance) from axis to torsion limiter and contact surface of paper money1Indicating the frictional force between the separator and the banknote in contact with the separator (i.e. the force which moves the banknote in the dispensing direction), N x μ2Indicating the friction between two contacting notes of a double note.
As a preferred embodiment, the banknote sorting mechanism further comprises a banknote digging wheel 3 (see fig. 1), and the banknote digging wheel 3 is used for digging banknotes from the stacked banknotes 4 and sending the dug banknotes to the double-roller gap between the banknote sorting wheel 1 and the torsion limiter 2.
According to the invention, the torsion limiter is used as the separating wheel, and is used for preventing the paper money in contact with the torsion limiter in the double-fed paper money from moving to the appointed paper money outputting direction when the paper money fed into the paper money separating wheel and the double-roller gap of the torsion limiter is the double-fed paper money; it can be seen that when the paper money entering the double-roller gap between the paper money separating wheel and the torsion limiter is the double-fed paper money, the pressure applied to the paper money in the double-roller gap by the paper money separating wheel and the torsion limiter is increased, correspondingly, the torsion applied to the torsion limiter by the paper money is also increased, and when the torsion is greater than the limiting torsion of the torsion limiter, the torsion limiter can change the rotation direction of the torsion limiter so as to prevent the paper money contacting with the torsion limiter in the double-fed paper money from moving to the appointed paper money outputting direction. According to the invention, the separation of the heavy paper money can be realized by replacing the separation wheel with the torque limiter, the accuracy of separating the paper money is improved, and compared with the mode of accurately controlling the gap between the pair rollers between the paper money separating wheel and the separation wheel in the prior art, the method is easy to realize and is beneficial to later maintenance.
