The embodiments described below with reference to the drawings are exemplary only for explaining the present utility model and should not be construed as a limitation to the present utility model.

[0047] Please refer to Figure 1 and Figure 2, this embodiment provides a cash recycling processing device. The cash recycling processing device includes a frame 10 and a cash box 20. The cash box 20 is detachably mounted on the frame 10. An optoelectronic sensor (not shown in the drawings) is mounted on the frame 10. The light guide member 2 of the cash box 20 cooperates with the light emitter and the light receiver of the optoelectronic sensor. For the cash recycling processing device provided in this embodiment, when the cash box 20 is mounted on the frame 10, the light guide member 2 of the cash box 20 cooperates with the light emitter and the light receiver of the optoelectronic sensor on the frame 10 to detect the banknote capacity in the cash box. Then, when the cash box is full of banknotes, the maintenance personnel can timely take out the banknotes in the cash box 20, or when the number of banknotes in the cash box is insufficient, the maintenance personnel can timely load banknotes into the cash box 20. Since the optoelectronic sensor is arranged outside the cash box 20, there is no need for an electrical connection between the optoelectronic sensor and the cash box 20. Compared with the prior art, there is no need to disassemble and assemble the optoelectronic sensor when disassembling and assembling the cash box 20, and thus there is no need to plug and unplug the connecting wire of the optoelectronic sensor, which simplifies the operation steps of disassembling and assembling the cash box 20 and improves the efficiency of disassembling or installing the cash box 20.

[0048] Optionally, please continue to refer to Figure 1 , the cash recycling processing device further includes a banknote input device 30, a banknote output device 40 and a reading device 50. The banknote input device 30 is used to receive banknotes put in by users. The reading device 50 is used to collect information of banknotes. The banknote output device 40 is used to output banknotes to users.

[0049] Optionally, please continue to refer to Figure 1 , the cash recycling processing device further includes a counterfeit money box 210, a recycling box 220, a storage box 230 and a loading box 240. Among them, the counterfeit money box 210 is used to receive counterfeit money input by the banknote input device 30 during deposit; the recycling box 220 is used to receive banknotes input by the banknote input device 30 during deposit and output banknotes during withdrawal; the storage box 230 is used to receive large-denomination banknotes during deposit, receive abnormal banknotes identified by the reading device 50 during withdrawal and loading, and receive banknotes output by the recycling box 220 during cash clearing; the loading box 240 is used to load banknotes into the recycling box 220. Among them, at least one of the counterfeit money box 210, the recycling box 220, the storage box 230 and the loading box 240 includes the above-mentioned cash box 20.

[0050] Optionally, please refer to Figure 3The banknote box 20 includes a box body 1, a light guide 2 and a detection member 3. The box body 1 includes a receiving cavity 11 for receiving banknotes, and the receiving cavity 11 has a bottom wall 111 for stacking banknotes; the light guide 2 is arranged on the box body 1, and the light guide 2 is configured to cooperate with the light emitter and the light receiver of the photoelectric sensor; the detection member 3 is movably connected to the box body 1, and the detection member 3 includes a linked force-bearing part 31 and a blocking part 32, and the force-bearing part 31 can pass through the bottom wall 111 to enter the receiving cavity 11 and abut against the banknotes stacked on the bottom wall 111, and the force-bearing part 31 always has a force-bearing part 31 along the receiving cavity 11. When the number of banknotes stacked in the accommodating cavity 11 reaches a set value, the force-bearing portion 31 moves to a preset position under the action of an external force, and drives the blocking portion 32 to switch from one of the blocking state and the avoidance state to the other of the two. When the blocking portion 32 is in the avoidance state, the light guide 2 can transmit the light emitted by the light emitter to the light receiver. When the blocking portion 32 is in the blocking state, the blocking portion 32 prevents the light guide 2 from transmitting the light emitted by the light emitter to the light receiver.

[0051] The banknote box 20 provided in this embodiment is installed on the frame 10. When the light receiver of the photoelectric sensor receives the light emitted by the light transmitter, the photoelectric sensor outputs a first signal (e.g., a high level). When the light receiver cannot receive the light emitted by the light transmitter, the photoelectric sensor outputs a second signal (e.g., a low level). Thus, when the force-bearing portion 31 drives the blocking portion 32 to change from one of the blocking state and the avoidance state to the other of the two, the output signal of the photoelectric sensor switches synchronously between the first signal and the second signal. Since the photoelectric sensor is arranged outside the banknote box 20, there is no need for electrical connection between the photoelectric sensor and the banknote box 20. When disassembling the banknote box 20, there is no need to disassemble the photoelectric sensor, and there is no need to plug and unplug the connecting wire of the photoelectric sensor. This simplifies the operation steps of disassembling the banknote box 20 and improves the efficiency of disassembling or installing the banknote box 20.

[0052] Optionally, the force-bearing portion 31 has an initial position entering the accommodating cavity 11, and the force-bearing portion 31 always has a tendency to move to the initial position along the direction of entering the accommodating cavity 11 under the action of the reset force, and the reset force enables the force-bearing portion 31 to remain in the initial position. Specifically, the banknote box 20 provided in this embodiment is only used for collecting banknotes or only for outputting banknotes. Among them, when the banknote box 20 is only used to collect banknotes, as the number of banknotes stacked on the bottom wall 111 increases, the gravity of the banknotes stacked on the bottom wall 111 also increases. When the number of banknotes stacked in the accommodating chamber 11 reaches a set value, the number of banknotes in the banknote box 20 is already sufficient (for example, the banknote box 20 is already full or about to be full), and the force-bearing part 31 overcomes the reset force under the action of the gravity of the banknotes (that is, the external force is the gravity of the banknotes) and moves to a preset position in the direction of exiting the accommodating chamber 11, and the force-bearing part 31 drives the blocking part 32 to switch from one of the blocking state and the avoidance state to the other of the two. At the same time, the output signal of the photoelectric sensor switches synchronously between the first signal and the second signal. According to the change of the output signal of the photoelectric sensor, it can be judged that the number of banknotes in the banknote box 20 is already sufficient, so that the maintenance personnel can take out the banknotes in the banknote box 20 in time; when the banknote box 20 is only used to output banknotes When the number of banknotes stacked on the bottom wall 111 decreases, the gravity of the banknotes stacked on the bottom wall 111 also decreases. When the number of banknotes stacked in the accommodating chamber 11 reaches the set value, the number of banknotes in the banknote box 20 is insufficient (for example, the banknotes in the banknote box 20 have been emptied or are about to be emptied). The force-bearing portion 31 moves to the preset position along the direction of entering the accommodating chamber 11 under the action of the reset force (that is, the external force is the reset force), and the force-bearing portion 31 drives the blocking portion 32 to change from one of the blocking state and the avoidance state to the other of the two. At the same time, the output signal of the photoelectric sensor switches synchronously between the first signal and the second signal. According to the change of the output signal of the photoelectric sensor, it can be judged that the number of banknotes in the banknote box 20 is insufficient, so that the maintenance personnel can fill the banknotes into the banknote box 20 in time. It should be noted that when the banknotes in the banknote box 20 have been emptied, that is, when the set value is zero, the preset position coincides with the initial position. Therefore, the cash box 20 provided in this embodiment, through the cooperation of the light guide 2, the detection component 3 and the photoelectric sensor, can be used to detect whether the number of banknotes in the cash box 20 is sufficient, so as to promptly remind the operator to clean the cash box 20, and can also be used to detect whether the number of banknotes in the cash box 20 is insufficient, so as to promptly remind the operator to fill the banknotes into the cash box 20.

[0053] Optionally, the frame 10 is provided with a main control unit (not shown in the drawings), and the photoelectric sensor is electrically connected to the main control unit via a connecting line. The main control unit is used to receive a first signal or a second signal output by the photoelectric sensor, and judge the banknote capacity status in the cash box 20 according to the first signal or the second signal and issue a prompt message to prompt the maintenance personnel to maintain the cash box 20.

[0054] Optionally, see Figure 3 and Figure 4 , the detection member 3 further includes a connecting portion 33 connected between the force-bearing portion 31 and the blocking portion 32, the connecting portion 33 is rotatably connected to the box body 1 through the rotating shaft 34, the force-bearing portion 31 can rotate around the axis of the rotating shaft 34 and drive the blocking portion 32 to rotate synchronously around the axis of the rotating shaft 34, so that the blocking portion 32 can switch between the blocking state and the avoidance state; under the gravity of the blocking portion 32, the force-bearing portion 31 always has a tendency to rotate in the direction of entering the accommodating chamber 11; or, the banknote box 20 further includes a first elastic member (not shown in the drawings), the first elastic member is connected between the detection member 3 and the box body 1, and under the elastic force of the first elastic member, the force-bearing portion 31 always has a tendency to rotate in the direction of entering the accommodating chamber 11. It should be understood that in this embodiment, the reset force is the gravity of the blocking portion 32, the force of the first elastic member, or the combined force of the two. In this way, under the action of the gravity of the blocking part 32 and / or the elastic force of the first elastic member, the force-bearing part 31 can enter the accommodating chamber 11 and stably abut against the banknotes stacked on the bottom wall 111, wherein the rotation direction of the rotating shaft 34 is determined by comparing two torques, one of which is the product of the gravity of the banknotes borne by the force-bearing part 31 and the arm of force between the force-bearing part 31 and the rotating shaft 34; the other torque is the product of the gravity of the blocking part 32 itself or the elastic force of the first elastic member borne by the blocking part 32 and the arm of force between the blocking part 32 and the rotating shaft 34. By comparing the two torques, it is determined whether the blocking part 32 is in a blocking state or an avoidance state, thereby ensuring the reliability of the switching of the blocking part 32 between the blocking state and the avoidance state. Preferably, please refer to Figure 4 In this embodiment, the housing 1 is provided with a mounting groove 15, the shaft 34 is fixed to the connecting portion 33, and the shaft 34 is rotatably inserted into the mounting groove 15. In other embodiments, the shaft 34 may be fixed to the housing 1, the connecting portion 33 is provided with a mounting groove 15, and the shaft 34 is rotatably inserted into the mounting groove 15.

[0055] As an alternative solution, the detection member 3 also includes a connecting portion 33 connected between the force-bearing portion 31 and the blocking portion 32, the connecting portion 33 is slidably connected to the box body 1, the force-bearing portion 31 can translate relative to the box body 1 in the direction of entering the accommodating chamber 11 and drive the blocking portion 32 to translate synchronously in the direction of entering the accommodating chamber 11, so that the blocking portion 32 can switch to a blocking state or an avoidance state; the banknote box 20 also includes a second elastic member (not shown in the drawings), the second elastic member is connected between the connecting portion 33 and the box body 1, and under the action of the elastic force of the second elastic member, the force-bearing portion 31 always has a tendency to translate in the direction of entering the accommodating chamber 11. It should be understood that in this embodiment, the reset force is the force of the second elastic member. With such a configuration, under the action of the elastic force of the second elastic member, the force-bearing portion 31 can enter the accommodating cavity 11 and stably abut against the banknotes stacked on the bottom wall 111, wherein the comparison between the weight of the banknotes borne by the force-bearing portion 31 and the elastic force of the second elastic member borne by the blocking portion 32 determines whether the blocking portion 32 is in a blocking state or an avoidance state, and can also ensure the reliability of the switching between the blocking state and the avoidance state of the blocking portion 32. Preferably, the direction in which the force-bearing portion 31 enters the accommodating cavity 11 is parallel to the stacking direction of the banknotes.

[0056] Please refer to Figure 4 and Figure 5 In this embodiment, the light guide 2 includes a light input column 21 and a light output column 22 that are spaced apart, and a light guiding portion 23 connected between the light input column 21 and the light output column 22. The light input column 21 is used to receive light emitted by the light transmitter, and the light guiding portion 23 is used to propagate the light from the light input column 21 to the light output column 22. The light output column 22 is used to propagate the light to the light receiver; when the blocking portion 32 is in a blocking state, the blocking portion 32 blocks between the light output column 22 and the light receiver, and when the blocking portion 32 is in an avoidance state, the blocking portion 32 withdraws from between the light output column 22 and the light receiver. Among them, when the blocking part 32 withdraws from between the light output column 22 and the light receiver, the light emitted by the light emitter enters the light guide 2 from the light input column 21, and is emitted from the light output column 22 through the light guide 23, and is received by the light receiver, and the photoelectric sensor outputs a first signal; when the blocking part 32 blocks between the light output column 22 and the light receiver, the light emitted by the light emitter enters the light guide 2 from the light input column 21, and is emitted from the light output column 22 through the light guide 23, and the emitted light is blocked by the blocking part 32 and cannot be received by the light receiver, and the photoelectric sensor outputs a second signal, thereby realizing that when the blocking part 32 changes from one of the blocking state and the avoidance state to the other of the two, the output signal of the photoelectric sensor switches synchronously between the first signal and the second signal. Preferably, the blocking part 32 includes a light shielding plate, and when the blocking part 32 is in the blocking state, the light shielding plate blocks between the light output column 22 and the light receiver. Further preferably, please refer to Figure 5The light guide portion 23 includes a first reflecting surface 24 and a second reflecting surface 25 . The light received by the incident light column 21 is reflected by the first reflecting surface 24 and the second reflecting surface 25 to the light output column 22 in sequence.

[0057] As an alternative solution, when the blocking portion 32 is in the blocking state, the blocking portion 32 blocks between the light emitter and the light incident column 21, and when the blocking portion 32 is in the avoidance state, the blocking portion 32 withdraws from between the light emitter and the light incident column 21; or, when the blocking portion 32 is in the blocking state, the blocking portion 32 simultaneously blocks between the light output column 22 and the light receiver and between the light incident column 21 and the light emitter, and when the blocking portion 32 is in the avoidance state, the blocking portion 32 simultaneously withdraws from between the light output column 22 and the light receiver and between the light incident column 21 and the light emitter; or, when the blocking portion 32 is in the blocking state, the blocking portion 32 blocks between the first reflecting surface 24 and the second reflecting surface 25, and when the blocking portion 32 is in the avoidance state, the blocking portion 32 withdraws from between the first reflecting surface 24 and the second reflecting surface 25. It is also possible to achieve that when the blocking portion 32 changes from one of the blocking state and the avoidance state to the other, the output signal of the photoelectric sensor switches synchronously between the first signal and the second signal.

[0058] Optionally, in this embodiment, the light input column 21, the light output column 22, and the light guide 23 are integrally formed, which can reduce the number of components and facilitate the installation efficiency of the light guide 2. Further optionally, the light guide 2 is made of a light guide material such as acrylic, glass or PC.

[0059] Optionally, see Figure 2 , Figure 3 and Figure 6 The housing 1 further includes an installation cavity 12, and a first light-transmitting hole 13 and a second light-transmitting hole 14 both connected to the installation cavity 12. The detection member 3 and the light-guiding member 2 are both installed in the installation cavity 12. The first light-transmitting hole 13 is opposite to the light incident column 21 and is arranged at intervals, and the second light-transmitting hole 14 is opposite to the light exit column 22 and is arranged at intervals; when the blocking portion 32 is in a blocking state and the blocking portion 32 blocks between the light emitter and the light incident column 21, the blocking portion 32 blocks between the light incident column 21 and the first light-transmitting hole 13; or, when the blocking portion 32 is in a blocking state and the blocking portion 32 blocks between the light exit column 22 and the light receiver, the blocking portion 32 blocks between the light exit column 22 and the second light-transmitting hole 14. With such arrangement, the light emitted by the optical transmitter can enter the mounting cavity 12 through the first light-transmitting hole 13 and propagate to the light-incoming column 21, and the light emitted by the light-exiting column 22 can propagate to the optical receiver through the second light-transmitting hole 14. By installing both the detection component 3 and the light guide component 2 in the mounting cavity 12, the influence of external interference light on the detection accuracy is avoided, and dust falling on the light guide component 2 can be reduced, thereby further improving the detection accuracy.

[0060] Optionally, please refer to Figure 6 , the size of the first light-transmitting hole 13 is larger than that of the second light-transmitting hole 14. When the blocking portion 32 is in the blocking state, the blocking portion 32 blocks between the light-emitting column 22 and the second light-transmitting hole 14. By making the size of the first light-transmitting hole 13 larger than that of the second light-transmitting hole 14, the light incident amount of the light guide member 2 is increased, thereby reducing the influence of the propagation loss of light between the light-incident column 21 and the light-emitting column 22 on the detection accuracy; at the same time, when the blocking portion 32 is in the blocking state, the blocking portion 32 can reliably block the light propagation between the light-emitting column 22 and the light receiver, reducing the requirement for the movement accuracy of the detecting member 3.

[0061] Optionally, please refer to Figure 5 and Figure 6 , the cross-sections of the light-incident column 21 and the light-emitting column 22 are both circular and their diameters are equal. The first light-transmitting hole 13 is a circular hole, the diameter of the first light-transmitting hole 13 is greater than or equal to the diameter of the light-incident column 21, the dimension of the second light-transmitting hole 14 in the direction in which the force-receiving portion 31 enters the accommodating cavity 11 is smaller than the diameter of the light-emitting column 22, and the first light-transmitting hole 13 is centered with the light-incident column 21, and the second light-transmitting hole 14 is centered with the light-emitting column 22. With such a setting, the accuracy requirement for the movement stroke of the blocking portion 32 in the direction in which the force-receiving portion 31 enters the accommodating cavity 11 is reduced, and the detection sensitivity of the banknote capacity in the accommodating cavity 11 is improved; and further, when the blocking portion 32 is in the blocking state, the reliability of the blocking portion 32 to block the light propagation between the light-emitting column 22 and the light receiver is enhanced.

[0062] In other embodiments, the cross-sections of the light-incident column 21 and the light-emitting column 22 are both circular and their diameters are equal. The first light-transmitting hole 13 is a first square hole, the side length of the first square hole is equal to the diameter of the light-incident column 21, the second light-transmitting hole 14 is a second square hole, and the side length of the second square hole is smaller than the diameter of the light-emitting column 22.

[0063] Optionally, please refer to Figure 7, the cash box 20 further includes a pressing plate 4. The pressing plate 4 is disposed opposite to the bottom wall 111 along the stacking direction of the banknotes. The pressing plate 4 is movably connected to the box body 1, and the pressing plate 4 can approach or move away from the bottom wall 111 relative to the box body 1. The pressing plate 4 is used to press the banknotes in the accommodating cavity 11 towards the force receiving portion 31; the pressing plate 4 is provided with an avoidance groove 41. When there are no banknotes in the accommodating cavity 11, the force receiving portion 31 passes through the bottom wall 111 and enters the accommodating cavity 11 and extends into the avoidance groove 41. Such a setting enables the detection member 3 to detect whether there are banknotes in the accommodating cavity 11. As long as there are banknotes in the accommodating cavity 11, and even if there is only one banknote, the banknotes can be stacked on the bottom wall 111 under the action of the pressing plate 4 and simultaneously press against the force receiving portion 31, so that the banknotes can reliably apply a pressure to the force receiving portion 31 in the direction of exiting the accommodating cavity 11; when there are no banknotes in the accommodating cavity 11, that is, when the set value is zero, the force receiving portion 31 moves in the direction of entering the accommodating cavity 11 to the preset position where it is inserted into the avoidance groove 41 under the action of the restoring force, so that the force receiving portion 31 is not under the pressure of the pressing plate 4, ensuring that the blocking portion 32 can reliably switch between the blocking state and the avoidance state, and improving the reliability of detecting the presence or absence of banknotes in the accommodating cavity 11.

[0064] Optionally, please refer to Figure 8 , the cash box 20 further includes a conveying assembly 5. The conveying assembly 5 is used to drive the banknotes in the accommodating cavity 11 to move along the banknote discharging direction. Along the banknote discharging direction, the force receiving portion 31 is located upstream of the conveying assembly 5; along the banknote discharging direction, the force receiving portion 31 has a first end portion and a second end portion, and the first end portion is located upstream of the second end portion. The first end portion is lower than the bottom wall 111, or the first end portion is flush with the bottom wall 111, and the second end portion extends obliquely from the first end portion towards the pressing plate 4. Such a setting makes the first end portion and the second end portion of the force receiving portion 31 be obliquely arranged to form a guiding surface. When the conveying assembly 5 drives the banknotes in the accommodating cavity 11 to be discharged, the guiding surface can guide the banknotes to smoothly pass through the force receiving portion 31, and can prevent the damaged banknotes from being scratched when passing through the end portion of the force receiving portion 31, resulting in jamming.

[0065] Optionally, please continue to refer to Figure 8 , the conveying assembly 5 includes a banknote taking roller 51, a banknote separating roller 52 and a banknote blocking roller 53. The banknote taking roller 51 and the banknote separating roller 52 are both disposed on the bottom wall 111, and along the banknote discharging direction, the banknote taking roller 51 is located upstream of the banknote separating roller 52. The banknote taking roller 51 and the banknote separating roller 52 are both used to drive the banknotes to move. The banknote blocking roller 53 cooperates with the banknote separating roller 52 to prevent the overlapping banknotes from passing between the banknote separating roller 52 and the banknote blocking roller 53.

[0066] Optionally, please refer to Figure 3, the accommodating cavity 11 has a first side wall 112 and a second side wall 113 that are parallel and spaced apart along the width direction of the banknote. The distance between the first side wall 112 and the second side wall 113 is adapted to the width of the banknote, and the force-receiving part 31 is disposed centrally relative to the first side wall 112 and the second side wall 113. With such a setting, the banknotes in the accommodating cavity 11 can reliably press against the force-receiving part 31, improving the reliability of detecting the number of banknotes in the accommodating cavity 11.
