Description

Technical Field

[0001] This utility model relates to banknote sorting machines, and more particularly to a banknote sorting machine that is easy to maintain. Background Technology

[0002] A banknote sorting machine is a financial device specifically designed for the automated identification, classification, counting, and sorting of banknotes in circulation. As shown in Chinese Patent No. CN202020888799.3, "A New Type of Banknote Sorting Machine," a control system sends signals to a drive device that rotates a guide block, thereby changing the direction of the banknotes.

[0003] However, because banknote sorting machines have multiple banknote passages and moving parts, during the high-speed, continuous transmission of banknotes, issues such as folds, sticking, moisture, uneven thickness, or foreign objects inside the banknotes can cause jamming. Forcibly pulling out the banknotes may damage them. In addition, the related control and drive systems may also be damaged during use. In such cases, it is necessary to remove the left or right side panel to inspect the inside of the banknote sorting machine, but it is still difficult to clearly see the inside of the banknote sorting machine and perform the inspection. Therefore, how to make banknote sorting machines easy to inspect has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a banknote sorting machine that is easy to maintain by disengaging the interlocking device and rotating the inspection plate downwards to perform maintenance on the inside of the frame.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a frame with a left side plate and a right side plate on both sides, a banknote feeding plate located above the frame, a banknote dispensing plate located below the front side of the frame, a banknote receiving platform located above the banknote dispensing plate, a banknote passing plate located between the banknote feeding plate and the banknote dispensing plate, a banknote passing channel, a rotatably mounted changing device on the frame, a first passage located above the changing device, a second passage located below the changing device, and a transmission structure for moving banknotes. The banknote passing channel is connected to the first passage or the second passage by rotating the changing device. A left partition is mounted on the right side of the left side plate and a right partition is mounted on the left side of the right side plate on the frame. The model also includes a maintenance plate rotatably mounted on the rear side of the frame and an interlocking device. The interlocking device is located between the maintenance plate and the right partition to enable the maintenance plate to connect with the right partition. A mating plate is provided on the rear side of the frame behind the changing device. The mating plate is rotatably mounted on the frame and linked with the maintenance plate.

[0006] The present invention is further configured to include a torsion spring. Each interlocking device includes a first locking member rotatably mounted on the inspection plate and a second locking member rotatably mounted on the right partition. The second locking member includes a rotating part and a mating part. The mating part is located behind the rotating part, and a guide post located below the mating part and a rotating shaft that drives the rotating part to rotate are installed on the right partition. The mating part is provided with a mating groove for the guide post to be inserted. The first locking member includes a force-applying part located below the mating part. One end of the torsion spring is located on the rotating shaft and the other end is located on the mating part so that the mating part moves downward.

[0007] The present invention is further configured such that: a limiting post is provided on the front side of the right partition plate at the rotating part, the rotating part includes a front abutment piece, and the rear end face of the abutment piece abuts against the circumferential of the limiting post.

[0008] The present invention is further configured such that: the mating part includes a mating surface at the bottom, the mating surface is inclined from front to back and from bottom to top, the force-applying part includes a contact surface at the top front side, the contact surface is inclined from front to back and from bottom to top, and the mating surface is in contact with the contact surface.

[0009] The present invention is further configured such that: a linkage shaft is fixedly installed on the inspection plate and the axial direction of the linkage shaft extends to the left and right; linkage rods are fixedly installed on both the left and right sides of the linkage shaft; and one end of each linkage rod is connected to the mating plate.

[0010] The present invention is further configured such that: the frame is mounted on an mounting plate above the mating plate; the channel changing component is rotatably mounted on the frame and includes a channel changing part on the rear side; the channel changing part abuts against the mounting plate to connect the banknote passage with the second passage, or the channel changing part abuts against the mating plate to connect the banknote passage with the first passage.

[0011] This utility model is further configured such that: the frame is rotatably mounted with a plurality of banknote dispensing wheels on the banknote dispensing plate side; the transmission structure includes a first wheel group rotatably mounted on the frame and located in the banknote passage and a second wheel group rotatably mounted on the frame and located in the first passageway; a first motor and a second motor are provided inside the frame; the second motor is fixedly mounted with a mating wheel; the frame includes a mounting shaft for inserting each banknote dispensing wheel; a first transmission wheel is mounted on the mounting shaft; the first transmission wheel is fixedly connected to the first motor; the first wheel group includes a second transmission wheel, a third transmission wheel, a fourth transmission wheel, a fifth transmission wheel, a sixth transmission wheel, and a... The transmission structure includes a seventh transmission wheel, an eighth transmission wheel located behind the second transmission wheel, a ninth transmission wheel located in front of the fifth transmission wheel, and an eleventh transmission wheel located behind the sixth transmission wheel. The second wheel set includes a tenth transmission wheel. The transmission structure also includes a first synchronous belt for transmission between the first, second, fourth, and ninth transmission wheels, a second synchronous belt for transmission between the eighth, tenth, and third transmission wheels, a third synchronous belt for transmission between the fifth and eleventh transmission wheels, and a fourth synchronous belt for transmission between the sixth, seventh, and mating wheels.

[0012] By adopting the above technical solution, the banknotes to be sorted are placed from the banknote infeed plate into the banknote passage. At this time, the transmission structure is activated to move the banknotes downward. After the required instructions are set, the control system identifies the banknotes. Optical sensors and thickness sensors are installed inside the frame. After identifying the banknotes that need to be sorted, the control system sends a signal to drive the changing mechanism downward, connecting the first passage with the banknote passage (the above is prior art and will not be described in detail here). At this time, the banknotes will move towards the first passage and fall onto the receiving table. The banknotes that do not need to be sorted can pass through the second passage and fall onto the banknote output plate after the changing mechanism is lifted upward. The system also includes a maintenance plate rotatably installed on the rear side of the frame and an interlocking device. The interlocking device is located between the maintenance plate and the right partition plate to enable the maintenance plate to connect with the right partition plate. A mating plate is provided on the rear side of the frame behind the changing mechanism. The mating plate is rotatably installed on the frame and linked with the maintenance plate. Similarly, an interlocking device exists between the inspection plate and the left partition, ensuring that when no maintenance is required, the inspection plate remains stably positioned at the rear of the frame and connected to the left and right partitions. When banknotes become stuck due to folds, adhesion, moisture, uneven thickness, or foreign objects, direct access to the frame's interior is difficult. Applying force to the inspection plate disengages it from the left and right partitions. As the inspection plate moves backward, the rear end of the mating plate moves downward, facilitating the insertion of tools or hands into the banknote passage, the first passage, and the second passage to remove the stuck banknotes. When no maintenance is required, flipping the inspection plate upwards connects the right partition to the inspection plate and the left partition to the inspection plate, ensuring reliable locking during operation, preventing accidental opening, and protecting operator safety.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-8As shown, this utility model discloses a banknote sorting machine that is easy to maintain, including a frame 3 with a left side plate 1 and a right side plate 2 mounted on the left and right sides, a banknote infeed plate 4 located above the frame 3, a banknote output plate 5 located below the front side of the frame 3, a banknote receiving platform 6 located above the banknote output plate 5, a banknote passing plate 7 located between the banknote infeed plate 4 and the banknote output plate 5, a banknote passing channel 8, a changing plate 9 rotatably mounted on the frame 3, a first passageway 10 located above the changing plate 9, a second passageway 11 located below the changing plate 9, and a transmission structure 12 for moving banknotes. The banknote passing channel 8 is connected to the first passageway 10 or the second passageway 11 by rotating the changing plate 9. The frame 3 has a left partition plate 13 mounted on the right side of the left side plate 1 and a left partition plate 13 mounted on the right side plate 2. 2. A right partition 14 is installed on the left side. The banknotes to be sorted are placed from the banknote infeed plate 4 into the banknote passage 8. At this time, the transmission structure is activated to move the banknotes downward. After the required instructions are set, the control system identifies the banknotes. Optical sensors and thickness sensors are installed inside the frame 3. After identifying the banknotes that need to be sorted, the control system sends a signal to drive the changing device 9 to press down, so that the first passage 10 is connected to the banknote passage 8 (the above is prior art and will not be described in detail here and is not shown in the figure). At this time, the banknotes will move towards the first passage 10 and fall onto the banknote receiving table 6. The banknotes that do not need to be sorted can pass through the second passage 11 and fall onto the banknote output plate 5 after the changing device 9 is lifted. It also includes a maintenance plate 15 rotatably mounted on the rear side of the frame 3 and an interlocking device 16. The interlocking device 16 is located between the maintenance plate 15 and the right partition 14 to enable the maintenance plate 15 to connect with the right partition 14. The frame 3 is provided with a mating plate 33 on the rear side of the switching component 9. The mating plate 33 is rotatably mounted on the frame 3 and linked with the maintenance plate 15. Similarly, the interlocking device 16 is also present between the maintenance plate 15 and the left partition 13, so that when no maintenance is required, the maintenance plate 15 can be stably located on the rear side of the frame 3 and remain connected with the left partition 13 and the right partition 14 without separation. This is useful when banknotes are jammed due to folding, sticking, moisture, uneven thickness, or foreign objects inside. When in use, it is difficult to directly access the inside of the frame 3. At this time, by applying force to the inspection plate 15, the inspection plate 15, which is rotatably installed on the rear side of the frame 3, is disconnected from the left and right partitions 14. As the inspection plate 15 moves backward, the rear end of the mating plate 33 can be moved downward, making it easier for operating tools or hands to reach into the banknote passage 8, the first passage and the second passage, so that the stuck banknotes can be completely removed. When no maintenance is needed, the inspection plate 15 is flipped upward so that the interlocking device 16 completes the connection between the right partition 14 and the inspection plate 15, and the left partition 13 and the inspection plate 15, ensuring that the inspection plate 15 is reliably locked during equipment operation, preventing accidental opening and ensuring the safety of operators.

[0017] The device also includes a torsion spring 17. The interlocking device 16 includes a first locking member 18 rotatably mounted on the inspection plate 15 and a second locking member 19 rotatably mounted on the right partition 14. The second locking member 19 includes a rotating part 20 and a mating part 21. The mating part 21 is located behind the rotating part 20, and a guide post 22 located below the mating part 21 and a rotating shaft 23 driving the rotating part 20 to rotate are mounted on the right partition 14. The mating part 21 is provided with a mating groove 24 for the guide post 22 to be inserted. The first locking member 18 includes a first locking member 18 rotatably mounted on the inspection plate 15 and a second locking member 19 rotatably mounted on the right partition 14. The second locking member 19 includes a rotating part 20 and a mating part 21. The force-applying part 25 is located below part 21. One end of the torsion spring 17 is located on the rotating shaft 23, and the other end is located on the mating part 21, so that the mating part 21 can move downward. The interlocking device 16 uses the cooperation of a first locking member 18 mounted on the inspection plate 15 and a second locking member 19 mounted on the right partition 14. When it is necessary to rotate the inspection plate 15 downward, since the force-applying part 25 of the first locking member 18 is located below the mating part 21 of the second locking member 19, the force-applying part 25, which moves backward, can push the mating part 21 forward and compress the torsion spring 17, thereby achieving the application of force. Part 25 moves away from below mating part 21, thereby enabling the inspection plate 15 to rotate downwards. It is noteworthy that after the inspection plate 15 completes its downward rotation, the force on mating part 21 disappears, and the elastic force of torsion spring 17 pushes mating part 21 downwards and backwards to achieve a reset. When the inspection plate 15 needs to be rotated upwards to connect with the frame 3 after maintenance, as the force-applying part 25 on the first locking member 18 approaches mating part 21, it needs to push mating part 21 open, causing mating part 21 to move upwards and forwards to compress torsion spring 17. When the inspection plate 15 is completed... After the upward rotation of 15 releases the force on the inspection plate 15, the torsion spring 17 drives the mating part 21 to reset and position it above the force-applying part 25. At this time, due to the restriction of the mating part 21, the inspection plate 15 will not rotate arbitrarily without the action of external force, thus improving the stability of the cleaning machine. Furthermore, the torsion spring 17 acts directly on the mating part 21, giving it a continuous downward and backward tendency, ensuring a firm locking state. Even if vibration occurs during equipment operation, the first locking member 18 and the second locking member 19 cannot separate, resulting in high safety.

[0018] Preferably, the right partition 14 is provided with a limiting post 26 on the front side of the rotating part 20. The rotating part 20 includes a front abutment piece 27. The rear end face of the abutment piece 27 abuts against the circumferential of the limiting post 26. Since the abutment piece 27 on the rotating part 20 of the second locking member 19 abuts against the limiting post 26 on the right partition 14, the abutment piece 27 cannot cross the limiting post 26, thus restricting the rotation trajectory of the second locking member 19. Therefore, the movement trajectory of the second locking member 19 can only rotate counterclockwise when the torsion spring 17 is squeezed, so that the abutment piece 27 moves forward away from the limiting post 26 and returns to abutting against the two. It can also prevent the torsion spring 17 from failing due to excessive torsion and reduce the jamming or damage caused by excessive swing of the mating part 21 during the unlocking process.

[0019] The inspection plate 15 is equipped with a wrench 30, which provides a clear and easy-to-grip point for the user's fingers or palm, making the opening and closing of the inspection plate 15 smoother and less strenuous. During operation, the user can naturally hook the wrench 30 with their fingers or grasp it with their hand to perform push / pull operations, making the operation intuitive and comfortable.

[0020] The inspection plate 15 is fixedly mounted with a linkage shaft 31, which extends axially to the left and right. Both sides of the linkage shaft 31 are fixedly mounted with linkage rods 32 by welding or other means. One end of each linkage rod 32 is connected to a mating plate 33. Since each linkage rod 32 is fixed to the linkage shaft 31, and the linkage shaft 31 is fixed to the inspection plate 15, the rear side of each linkage rod 32 can rotate synchronously as the inspection plate 15 rotates. Therefore, during the downward rotation of the inspection plate 15, the rear side of each linkage rod 32 can move downward and backward (i.e., clockwise), thereby pulling the rear side of the mating plate 33 backward, which facilitates maintenance.

[0021] The frame 3 is mounted on a mounting plate 34 above the mating plate 33. The switching component 9 is rotatably mounted on the frame 3 and includes a switching section 35 on the rear side. The switching section 35 abuts against the mounting plate 34 to connect the banknote passage 8 with the second passage 11, or the switching section 35 abuts against the mating plate 33 to connect the banknote passage 8 with the first passage 10. The switching component 9 has two states: abutting against the mounting plate 34 or the mating plate 33, corresponding to two working modes: the banknote passage 8 connecting with the first passage 10 or the banknote passage 8 connecting with the second passage 11, respectively. This can be used to distinguish banknotes under different needs.

[0022] The frame 3 is rotatably mounted with a plurality of banknote dispensing wheels 36 on the banknote dispensing plate 5 side. The transmission structure includes a first wheel set rotatably mounted on the frame 3 and located in the banknote passage 8, and a second wheel set rotatably mounted on the frame 3 and located in the first passage 10. A first motor 37 and a second motor 38 are provided inside the frame 3. The second motor 38 is fixedly mounted with a mating wheel 39. The frame 3 includes a mounting shaft 40 for inserting each banknote dispensing wheel 36. A first transmission wheel 41 is mounted on the mounting shaft 40. The first transmission wheel 41 is fixedly connected to the first motor 37. The first wheel set includes... The transmission structure includes a second transmission wheel 42, a third transmission wheel 43, a fourth transmission wheel 44, a fifth transmission wheel 45, a sixth transmission wheel 46, a seventh transmission wheel 47, an eighth transmission wheel 48 located behind the second transmission wheel 42, a ninth transmission wheel 49 located in front of the fifth transmission wheel 45, and an eleventh transmission wheel 51 located behind the sixth transmission wheel 46. The second wheel set includes a tenth transmission wheel 50. The transmission structure also includes a first synchronous belt 52 disposed between the first transmission wheel 41, the second transmission wheel 42, the fourth transmission wheel 44, and the ninth transmission wheel 49, and a transmission belt disposed on the eighth transmission wheel 48. The second synchronous belt 53 between the tenth transmission wheel 50 and the third transmission wheel 43 transmits the third synchronous belt 54 between the fifth transmission wheel 45 and the eleventh transmission wheel 51, and the fourth synchronous belt 55 between the sixth transmission wheel 46, the seventh transmission wheel 47, and the mating wheel 39. The second transmission wheel 42 and the eighth transmission wheel 48 are coaxially arranged, the fifth transmission wheel 45 and the ninth transmission wheel 49 are synchronously arranged, and the sixth transmission wheel 46 and the eleventh transmission wheel 51 are synchronously arranged. 1. Due to the presence of the first motor 37 and the second motor 38, during normal operation, the second motor 37... 8 plays a leading role in driving the rotation of this transmission structure. At the same time, the power can be transmitted through the one-way clutch, i.e., the one-way bearing (located between the sixth transmission wheel 46 and the eleventh transmission wheel 51) in the transmission structure 12, so that all components can operate at the same speed. When the user presets a certain amount, but the amount in the banknote channel 8 exceeds the preset amount, or when there is a banknote jam and it is necessary to stop the banknote feeding and want to empty the banknotes in the second aisle 11, the one-way clutch in the frame 3 located in the transmission structure can cut off the power, so that the banknotes in the second aisle 11 can still move towards the banknote dispensing plate 5; 2.When it is necessary to move the banknotes located on the banknote infeed plate 4 toward the banknote dispensing plate 5 or the banknote receiving table 6, in addition to adjusting the guide mechanism 9, the second motor 38 is started, which causes the output shaft of the second motor 38 to drive the mating wheel 39 to rotate. At this time, the fourth synchronous belt 55, which is located between the mating wheel 39, the sixth transmission wheel 46, and the seventh transmission wheel 47, rotates. Since the sixth transmission wheel 46 and the eleventh transmission wheel 51 are coaxially arranged, the rotation of the sixth transmission wheel 46 drives the eleventh transmission wheel 51 to rotate, causing the third synchronous belt 54, which is located between the eleventh transmission wheel and the fifth transmission wheel 45, to move. At this time, the fifth transmission wheel 54... Wheel 45 and the ninth transmission wheel 49 are coaxially arranged. As the fifth transmission wheel 45 rotates, the ninth transmission wheel 49 rotates accordingly, causing the first synchronous belt 52, which is positioned between the ninth transmission wheel 49, the first transmission wheel 41, the second transmission wheel 42, and the fourth transmission wheel 44, to move. Simultaneously, the rotation of the second transmission wheel 42 drives the coaxial third transmission wheel 43 to rotate, and the third transmission wheel 43 transmits torque to the second synchronous belt 53, causing the eighth, tenth, and third transmission wheels 43, located within the second synchronous belt 53, to rotate. This, in turn, causes the banknotes loaded from the banknote feeding plate 4 to move from the banknote passage 8 towards the first passage 10 or the second passage 11.

[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
