Description

Technical Field

[0001] This application relates to the technical field of financial equipment, and in particular to a coin-carrying device, a banknote sorting device, and an application method thereof. Background Technology

[0002] In the financial sector, the core functions of cash processing equipment such as banknote counters and sorting machines heavily rely on the banknote feeding device. This device not only needs to stably and continuously transport banknotes, but also needs to accurately identify foreign objects such as tape attached to the banknote surface to prevent abnormal banknotes from entering subsequent circulation processes or damaging the internal components of the equipment.

[0003] Current mainstream banknote-running devices typically include a fixed wheel assembly and an image recognition module. The fixed wheel assembly facilitates the continuous high-speed movement of banknotes, while image recognition is used to detect foreign objects on the banknote surface, such as glue, oil stains, and ink marks. Specifically, the image recognition module collects visual features such as grayscale and texture on the banknote surface to determine the presence of foreign objects. This solution is effective in identifying non-transparent foreign objects.

[0004] Regarding the aforementioned solutions, the inventors believe that the following defects exist: When the adhesive on the banknote surface is transparent tape, its visual features will be highly integrated with the banknote body when the transparent tape is attached to the banknote surface. The transparent tape will not change the grayscale distribution of the original pattern of the banknote, and the image recognition module will find it difficult to capture its outline through grayscale differences. Even if the tape has slight refraction, it is easily masked by interference signals such as ink reflection and fine creases on the banknote surface, causing the foreign object features to be submerged. Therefore, it is difficult to accurately detect the presence of transparent tape based on the image recognition function. Summary of the Invention

[0005] In order to facilitate the detection of whether there is transparent tape on banknotes, this application provides a banknote feeding device, a banknote sorting device, and an application method.

[0006] This application provides a coin feeding device, including a frame, a first mounting base rotatably connected to the frame, a pressing wheel rotatably connected to the first mounting base, and an elastic pressing mechanism mounted on the frame; the elastic pressing mechanism includes a second mounting base slidably connected to the frame, the second mounting base being slidable and resetting, the second mounting base having a pressing end, the first mounting base having a contact end, and the pressing end abutting against the contact end; the frame is also provided with a displacement detection element.

[0007] By adopting the above technical solution, when a banknote is pressed by the pressing wheel, the pressing wheel will be pressed, the first mounting seat will rotate, and the contact end will press against the pressure end, causing the second mounting seat to move. At this time, the displacement detection component can detect the displacement of the second mounting seat. Specifically, for banknotes without transparent tape on the surface, since the thickness of each banknote is consistent, the displacement of the second mounting seat caused by each banknote passing by is fixed. However, when there is transparent tape on the surface of the banknote, the displacement of the second mounting seat will usually be larger or smaller, and the displacement will deviate from the constant value. Therefore, based on the detection results of the displacement detection component, it is possible to quickly detect whether there is transparent tape on the banknote.

[0008] Preferably, the elastic pressing mechanism further includes a pressing spring sleeved on the second mounting base, with both ends of the pressing spring connected to the second mounting base and the frame, respectively.

[0009] By adopting the above technical solution, the pressing action of the pressing spring can make the pressing wheel press the banknotes that pass by, and the pressing spring can keep the contact end and the pressing end in contact and also make the second mounting base move and reset.

[0010] Preferably, the displacement detection element is one of a Hall sensor, a laser displacement sensor, a grating ruler, a visual displacement sensor, an inductive displacement sensor, a capacitive displacement sensor, or an ultrasonic displacement sensor.

[0011] Preferably, the abutting end includes an arc-shaped abutting portion, which contacts or makes line contact with the pressing end.

[0012] By adopting the above technical solution, the rotation of the first mounting base can facilitate the movement of the second mounting base through the contact between the contact end and the pressing end, and the wear is small due to the line contact or point contact method.

[0013] Preferably, one side of the pressing wheel is the feeding area; the first mounting base includes a rotating ring rotatably connected to the frame, the axis of the rotating ring is in the same direction as the axis of the pressing wheel, and the abutting end is located on the side of the rotating ring away from the feeding area.

[0014] By adopting the above technical solution, banknotes can enter the contact pressing roller from the feeding area. The design of the above structural position makes it easy for the pressing roller and the first mounting base to be slightly rotated by the banknotes.

[0015] Preferably, the first mounting base has a limiting part, and the frame has a mating part, wherein the limiting part is located on the side of the mating part away from the feeding area.

[0016] By adopting the above technical solution, the interaction between the limiting part and the mating part can prevent the first mounting seat from rotating out of position.

[0017] Preferably, the first mounting base, pressing rollers, and elastic pressing mechanism are all provided in multiple ways, and the multiple pressing rollers are distributed in a straight line.

[0018] By adopting the above technical solution, it is easy to detect the coverage area of ​​the transparent tape on the banknote.

[0019] Preferably, the first mounting base is equipped with a measuring element for detecting the number of rotations of the pressing wheel.

[0020] By adopting the above technical solution, the number of rotations of the pressing wheel after each banknote is pressed and circulated is also constant. When the number of rotations is abnormal, it can be combined with the displacement of the second mounting seat to more accurately determine whether there is transparent tape on the banknote surface.

[0021] This application also discloses a banknote sorting device, including the aforementioned banknote feeding device.

[0022] By adopting the above technical solution, the presence of transparent tape on the surface of banknotes can be quickly detected without affecting the rapid circulation of banknotes.

[0023] This application also discloses an application method for the aforementioned coin-operated device, comprising the following steps: S1. The pressing wheel rotates to press the banknote to move. Foreign objects on the banknote surface drive the pressing wheel to make the first mounting base rotate. S2. The rotation of the first mounting base causes the contact end to rotate and press against the contact end, thereby causing the second mounting base to move. S3. The displacement detection component detects the displacement of the second mounting base to determine whether there are foreign objects on the banknote surface. By adopting the above technical solution, the detection results of the displacement detection device can be used to quickly determine whether there are any problems with the banknotes that have been circulated.

[0024] In summary, the present invention has at least one of the following beneficial technical effects: 1. When a banknote is pressed by the pressing wheel, the pressing wheel is pressed down, the first mounting seat rotates, and the contact end presses against the pressure end, causing the second mounting seat to move. At this time, the displacement detection device can detect the displacement of the second mounting seat. Specifically, for banknotes without transparent tape on the surface, since the thickness of each banknote is consistent, the displacement of the second mounting seat caused by each banknote passing by is fixed. However, when there is transparent tape on the surface of the banknote, the displacement of the second mounting seat usually becomes larger or smaller, and the displacement deviates from the constant value. Therefore, based on the detection results of the displacement detection device, it is possible to quickly detect whether there is transparent tape on the banknote. 2. The banknotes can enter the contact pressing roller from the feeding area. The design of the above-mentioned structural position allows the pressing roller and the first mounting base to be easily driven by the banknotes to rotate slightly. 3. This application also facilitates the detection of the coverage area of ​​transparent tape on banknotes; 4. The number of rotations of the pressing wheel after each banknote is pressed and circulated is constant. When the number of rotations is abnormal, the displacement of the second mounting seat can be used to more accurately determine whether there is transparent tape on the banknote surface.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0029] This application discloses a banknote feeding device. It is used to easily detect whether there is transparent tape on the banknote.

[0030] Reference Figure 1 and Figure 2 A coin feeding device includes a frame 1, a first mounting base 2 rotatably connected to the frame 1, a pressing wheel 3 rotatably connected to the first mounting base 2, and an elastic pressing mechanism 4 mounted on the frame 1. The pressing wheel 3 is in contact with the elastic pressing mechanism 4, and the rotation direction of the first mounting base 2 is the same as the rotation direction of the pressing wheel 3.

[0031] Reference Figure 2Specifically, the elastic pressing mechanism 4 includes a second mounting base 41 slidably connected to the frame 1. The second mounting base 41 can slide up and down and return to its original position. The bottom end of the second mounting base 41 has a pressing end 411, and the upper end of the first mounting base 2 has a contact end 21. The pressing end 411 abuts against the contact end 21. A pressing spring 42 is also sleeved on the second mounting base 41, and the two ends of the pressing spring 42 are respectively connected to the second mounting base 41 and the frame 1. The frame 1 is also provided with a displacement detection element 5, which can detect the displacement of the second mounting base 41. The displacement detection element 5 is one of a Hall sensor, a laser displacement sensor, a grating ruler, a visual displacement sensor, an inductive displacement sensor, a capacitive displacement sensor, or an ultrasonic displacement sensor.

[0032] When a banknote passes under the pressing wheel 3 and is pressed down by the pressing wheel 3, the pressing wheel 3 is pressed down, and the first mounting base 2 rotates clockwise. The contact end 21 presses against the pressing end 411, causing the second mounting base 41 to move upward. At this time, the displacement of the second mounting base 41 can be detected by the displacement detection element 5. For banknotes without transparent tape on the surface, since the thickness of each banknote is uniform, the displacement of the second mounting base 41 caused by each banknote passing by is fixed. However, when there is transparent tape on the surface of the banknote, the displacement of the second mounting base 41 usually becomes larger or smaller, and the displacement deviates from the constant value. Therefore, the presence of transparent tape on the banknote can be quickly detected based on the detection result of the displacement detection element 5.

[0033] It should be noted that banknotes covered with transparent tape are usually due to damage to the banknote. The banknote may be composed of multiple fragments glued together by the transparent tape. Typically, the banknote will become thicker after being covered with transparent tape, but there is also the possibility that the joints between the fragments of the damaged banknote will become thinner.

[0034] Reference Figure 2 In order to reduce wear when the contact end 21 comes into contact with the pressing end 411 and to facilitate the contact end 21 to press against the pressing end 411, the contact end 21 includes an arc-shaped contact portion 4111. The arc-shaped contact portion 4111 makes point contact or line contact with the pressing end 411. In this embodiment, the arc-shaped contact portion 4111 makes line contact with the pressing end 411.

[0035] Reference Figure 2 and Figure 3 To prevent the first mounting base 2 from rotating out of position, one side of the pressing wheel 3 is the feeding area 31. The first mounting base 2 has a limiting part 22, and the frame 1 has a mating part 11. The limiting part 22 is located on the side of the mating part 11 away from the feeding area 31.

[0036] Reference Figure 2 and Figure 4To facilitate the synchronous rotation of the pressing wheel 3 and the first mounting base 2 caused by the moving banknotes, the frame 1 includes a connecting shaft 12, and the first mounting base 2 includes a rotating ring 23 rotatably connected to the connecting shaft 12. The axis of the rotating ring 23 is in the same direction as the axis of the pressing wheel 3. The contact end 21 is located on the side of the rotating ring 23 away from the feeding area 31. The axis of the pressing wheel 3 is located between the position where the arc contact part 4111 and the contact end 411 are in contact with the axis of the rotating ring 23.

[0037] Reference Figure 2 and Figure 4 In order to roughly determine the coverage area and general shape of the transparent tape, the first mounting base 2, the pressing wheel 3, the elastic pressing mechanism 4 and the displacement detection element 5 are all provided in multiple ways. The multiple pressing wheels 3 are distributed in a straight line. In this embodiment, the first mounting base 2, the pressing wheel 3, the elastic pressing mechanism 4 and the displacement detection element 5 are all provided in two ways.

[0038] In this embodiment, when the displacement of one pressing roller 3 corresponding to the second mounting base 41 is a constant value, while the displacement of the other pressing roller 3 corresponding to the second mounting base 41 deviates from the constant value, it indicates that the transparent tape is located on the half of the banknote surface where the second mounting base 41 has an offset. Of course, in other embodiments, more pressing rollers 3 and related structures can be provided to more accurately determine the transverse range of the transparent tape on the banknote surface.

[0039] Reference Figure 2 The first mounting base 2 is equipped with a measuring element for detecting the number of rotations of the pressing wheel 3. The measuring element may be a non-contact encoder, a Hall sensor, or the like. A pressure sensor is also provided at the end of the pressing wheel 3.

[0040] Normally, even if there is transparent tape on the surface of the banknote, the rotation of the pressing roller 3 is relatively uniform. Only when the banknote has slight wrinkles or creases will the rotation of the pressing roller 3 change abruptly. However, at this time, the displacement sensor will also detect a non-constant displacement. Therefore, by detecting the number of rotations of the pressing roller 3, the presence of transparent tape can be misjudged. Specifically, even if the displacement of the second mounting base 41 deviates from a constant value, it does not mean that there is transparent tape on the banknote.

[0041] Because the coefficient of friction of the banknote surface is different from that of the transparent tape surface, the pressure roller 3 will press differently when pressing on the banknote surface and when pressing on the transparent tape surface. The lateral pressure or torque of the pressure roller 3 will produce slight fluctuations. These fluctuations will be detected by the pressure sensor, and the detection data of the pressure sensor will help determine the presence of the transparent tape.

[0042] The implementation principle of a banknote feeding device in this embodiment is as follows: When a banknote passes under the pressing wheel 3 and is pressed by the pressing wheel 3, the pressing wheel 3 will be pressed, the first mounting base 2 will rotate, and the contact end 21 will press against the pressing end 411, causing the second mounting base 41 to move upward. At this time, the displacement of the second mounting base 41 can be detected based on the displacement detection element 5. For banknotes without transparent tape on the surface, the displacement of the second mounting base 41 caused by each banknote passing by is fixed. However, when there is transparent tape on the surface of the banknote, the displacement of the second mounting base 41 usually becomes larger or smaller, and the displacement deviates from the constant value. Therefore, the presence of transparent tape on the banknote can be quickly detected based on the detection result of the displacement detection element 5.

[0043] This application also discloses a banknote sorting device including a banknote sorting device body 6, a set of mating wheels 61 inside the banknote sorting device body 6, and a banknote feeding device disposed opposite to the set of mating wheels 61. The banknote feeding device is installed inside the banknote sorting device body 6. The set of mating wheels 61 and the pressing wheel 3 form a banknote feeding gap in diameter, and the set of mating wheels 61 can rotate to help drive the banknotes to flow.

[0044] This application also discloses an application method for a coin-operated device, including the following steps: S1. The pressing wheel 3 rotates to press the banknote to move. Foreign objects on the banknote surface will drive the pressing wheel 3 to move, causing the first mounting base 2 to rotate around the axis of the rotating ring 23. S2. The first mounting base 2 rotates, causing the contact end 21 to rotate and press against the pressing end 411, thereby causing the second mounting base 41 to move upward and the pressing spring 42 to be compressed. S3, the displacement detection component 5 detects the displacement of the second mounting base 41 to determine whether there are foreign objects on the surface of the banknote.

[0045] Specifically, for banknotes without transparent tape on the surface, since each banknote has a uniform thickness, the displacement of the second mounting base 41 caused by each banknote passing by is fixed. However, when there is transparent tape on the surface of the banknote, the displacement of the second mounting base 41 usually becomes larger or smaller, and the displacement deviates from the constant value.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
