Description

Technical Field

[0001] This application relates to the field of banknote counting equipment technology, and more particularly to a banknote counting machine for the blind. Background Technology

[0002] To facilitate quick and accurate money counting for blind people, Chinese patent publication number CN221884330U, filed on January 19, 2024, discloses a money counting machine for the blind. By adding a blind-friendly switch and voice prompts to a conventional money counting machine, blind people can use the machine through touch and voice, thus solving the problem of blind people being unable to use money counting machines.

[0003] However, when counting large amounts of banknotes, the banknote counting machine can only hold a limited number of banknotes at a time. Since blind people cannot see the money, it is inconvenient to place the banknotes in batches before and after counting, which is not conducive to blind people counting banknotes when there are many banknotes. Utility Model Content

[0004] This application provides a banknote counting machine for the blind, which solves the problem of not being able to store a large amount of money.

[0005] This application provides a banknote counting machine for the blind, including a banknote counting machine body, a voice broadcasting component, rotating shafts, and a rotating plate. The top of the banknote counting machine body has a coin slot and a coin dispensing slot. The side of the banknote counting machine body closer to the coin slot is the front side, and the side of the banknote counting machine body closer to the coin dispensing slot is the rear side. The voice broadcasting component is disposed on the banknote counting machine body. The rotating shafts are configured in two sets, with the two sets of rotating shafts respectively disposed at the bottom front side and the bottom rear side of the banknote counting machine body. The rotating shafts are horizontally disposed along a direction perpendicular to the front and rear direction of the banknote counting machine body. The banknote counter body has two rotating plates, each corresponding to one of the two rotating shafts. One end of each rotating plate is rotatably mounted on the corresponding rotating shaft, and a snap-fit ​​protrusion is formed at the end of the rotating plate. A receiving groove facing the banknote counter body is formed between the rotating shaft and the snap-fit ​​protrusion. Snap-fit ​​grooves are provided on both the front and rear side walls of the banknote counter body. These grooves are located on the upper side of the rotating shaft, and each of the two snap-fit ​​grooves corresponds to one of the two snap-fit ​​protrusions on the two rotating plates. The snap-fit ​​protrusions extend into the snap-fit ​​grooves.

[0006] In addition to the voice broadcast component that helps blind people know the amount of banknotes, the banknote counter for the blind described in this application can also place coins separately on two rotating plates. When a group of coins is too large to be inserted into the coin slot at once, the group of coins can be placed in the receiving slot of the rotating plate near the coin slot, and the counted coins can be placed in the receiving slot of the rotating plate near the coin outlet, making it easier for the blind to count the banknotes. The rotating plates can be rotated and snapped onto the main body of the banknote counter for easy storage and unfolding, and for easy carrying and transporting of the banknote counter.

[0007] In some embodiments of this application, the receiving slot is square, and the area of ​​the receiving slot is larger than the area of ​​the coin. Having a larger area for the receiving slot facilitates the placement of the coin.

[0008] In some embodiments of this application, the edges of the rotating plate are rounded. The rounded corners prevent scratches when touched by blind people, improving safety.

[0009] In some embodiments of this application, the rotating plate further includes a flexible layer, which is fixedly disposed on the snap-fit ​​protrusion and pressed between the inner walls of the snap-fit ​​protrusion and the snap-fit ​​groove. The flexible layer allows the snap-fit ​​protrusion and the snap-fit ​​groove to be relatively fixed, improving the connection stability between the snap-fit ​​protrusion and the snap-fit ​​groove.

[0010] In some embodiments of this application, each rotating plate has two locking protrusions, which are spaced apart along an axis parallel to the rotating shaft. The front and rear sides of the banknote counter body each have two locking slots, so that each locking protrusion engages within one locking slot. The two locking protrusions and two locking slots correspond to each other, further improving the locking stability between the banknote counter body and the rotating plate.

[0011] In some embodiments of this application, the banknote counter for the blind also includes a counterfeit currency receiving area and a counterfeit currency plate. The counterfeit currency plate is fixedly mounted on a side wall of the banknote counter body perpendicular to the front-back direction. An opening is provided at the top of the counterfeit currency plate, forming a counterfeit currency receiving area between the counterfeit currency plate and the banknote counter body. The counterfeit currency receiving area formed between the counterfeit currency plate and the banknote counter body facilitates the storage of counterfeit currency.

[0012] In some embodiments of this application, the cross-sectional area of ​​the counterfeit currency receiving area gradually increases along the height direction. This gradual increase in the cross-sectional area makes it easier to insert and remove counterfeit currency.

[0013] In some embodiments of this application, the banknote counter for the blind also includes elastic plastic rivets and a Braille writing pen. The elastic plastic rivets are detachably mounted on the side wall of the banknote counter body, and the elastic plastic rivets and the counterfeit money receiving area are located on two opposite side walls of the banknote counter body. The Braille writing pen is hung on the elastic plastic rivets. The Braille writing pen facilitates recording for blind people when there are many banknotes, thus facilitating the banknote counting process.

[0014] In some embodiments of this application, the Braille writing pen includes Braille paper, a Braille board, a Braille pen, and a pen cap. The Braille paper, Braille board, and Braille pen facilitate writing for blind people, and the pen cap prevents the Braille pen from pricking the user. Attached Figure Description

[0025] To facilitate quick and accurate money counting for blind people, Chinese patent publication number CN221884330U, filed on January 19, 2024, discloses a money counting machine for the blind. By adding a blind-friendly switch and voice prompts to a conventional money counting machine, blind people can use the machine through touch and voice, thus solving the problem of blind people being unable to use money counting machines.

[0026] However, when counting large amounts of banknotes, the banknote counting machine can only hold a limited number of banknotes at a time. Since blind people cannot see the money, it is inconvenient to place the banknotes in batches before and after counting, which is not conducive to blind people counting banknotes when there are many banknotes.

[0027] Therefore, please refer to Figure 1 This application provides a banknote counting machine for the blind, including a banknote counting machine body 1, a voice broadcast component 2, a rotating shaft 3, and a rotating plate 4.

[0028] Please refer to Figure 1 The top of the banknote counter body 1 has a coin slot 11 and a coin outlet 12. The side of the banknote counter body 1 closest to the coin slot 11 is the front side, and the side of the banknote counter body 1 closest to the coin outlet 12 is the rear side. The banknote counter may have a banknote counting mechanism, a vibration prompt device, a banknote authenticity recognition module, and a blind operation panel. The coin slot 11 and the coin outlet 12 are simply openings on the banknote counter body 1 for placing and taking out banknotes.

[0029] Please refer to Figure 1The banknote counting mechanism can be composed of commonly used banknote feeding wheels, twisting wheels, and counting sensors found in existing banknote counting machines, enabling fast and accurate counting of banknotes one by one. The materials and friction of the feeding and twisting wheels are specially designed to ensure stable and smooth banknote transport, avoiding malfunctions such as paper jams. The counting sensor uses a high-precision model, accurately recording the number of banknotes that pass through.

[0030] The vibration feedback device provides tactile feedback to blind users through vibration while simultaneously announcing the number of banknotes counted. The device is installed on the control panel of the banknote counter for easy tactile feedback by blind users. The intensity and frequency of the vibration can be adjusted according to user needs; for example, the vibration intensity can be reduced for users who are more sensitive to vibration, while the intensity and frequency can be increased for users who require stronger feedback.

[0031] The banknote authenticity detection module can use a combination of technologies such as fluorescence detection, magnetic detection, and infrared detection to identify the authenticity of banknotes. When counterfeit banknotes are detected, the banknote counter not only stops counting banknotes, but the voice broadcast module will also issue a voice prompt saying "Counterfeit banknote detected." At the same time, the vibration prompt device will also emit a strong vibration different from that during normal banknote counting to attract the attention of blind users.

[0032] The control panel for the visually impaired features raised buttons, each with a unique shape and tactile feel, allowing blind users to operate the device by touch. The buttons include function keys such as start, stop, reset, and settings. For example, the start button is a round raised button, and the stop button is a square raised button, allowing users to quickly identify their function by touching the shape. The control panel also includes Braille labels that provide detailed explanations of the functions of each button, further facilitating operation for visually impaired users.

[0033] Please refer to Figure 1 The voice broadcast component 2 is installed on the main body 1 of the banknote counter. Connected to the counting sensor, the voice broadcast component 2 announces the current number of banknotes counted each time the counting sensor detects a banknote passing by. The voice broadcast component 2 uses clear and standard speech synthesis technology and can be set to multiple languages ​​and speaking speeds to meet the needs of different blind users. For example, users can choose to hear the banknotes in Mandarin, dialects, or other languages ​​according to their preferences, and can also adjust the speaking speed.

[0034] Please refer to Figure 1The rotating shaft 3 is configured in two sets, one on the front bottom side and the other on the rear bottom side of the banknote counter body 1. The rotating shaft 3 is horizontally mounted on the banknote counter body 1 along a direction perpendicular to its front-rear orientation. The rotating shaft 3 can be made of plastic or metal. It can be fixedly connected to the banknote counter body 1 via an ear plate or connecting post, ensuring a certain gap between the rotating shaft 3 and the body.

[0035] Please refer to Figure 1 The two rotating shafts 3 can have the same height and the same length, and the connection between the two rotating shafts 3 and the main body 1 of the banknote counter can be exactly the same.

[0036] Please refer to Figure 1 Two rotating plates 4 are provided, and the two rotating plates 4 correspond one-to-one with the two rotating shafts 3 respectively. One end of the rotating plate 4 is rotatably mounted on the corresponding rotating shaft 3. A snap-fit ​​protrusion 41 is formed at the end of the rotating plate 4. A receiving groove 42 facing the body 1 of the banknote counter is formed between the rotating shaft 3 and the snap-fit ​​protrusion 41.

[0037] Please refer to Figure 1 and Figure 2 The rotating plate 4 can be made of a non-metallic hard material. The rotating shaft 3 can pass through the hole inside the rotating plate 4 so that the rotating plate 4 can rotate around the rotating shaft 3. The rotating plate 4 can be made of plastic or wood. The two rotating plates 4 can be exactly the same, or the size of the rotating plate 4 near the front of the banknote counter can be larger than the size of the rotating plate 4 near the rear of the banknote counter.

[0038] The shape and size of the receiving grooves 42 in the two rotating plates 4 can be exactly the same. The receiving grooves 42 can be square grooves, and the edges of the receiving grooves 42 can also be rounded.

[0039] Please refer to Figure 1 The banknote counter body 1 has locking grooves 13 on both its front and rear side walls. These grooves 13 are located on the upper side of the rotating shaft 3, and each groove 13 corresponds to a locking protrusion 41 on one of the two rotating plates 4. The locking protrusions 41 extend into the locking grooves 13. The interlocking locking grooves 13 and locking protrusions 41 form a common mechanical connection structure, primarily used to achieve a secure assembly of the two components.

[0040] Please refer to Figure 1 The latching protrusion 41 and the latching groove 13 should cooperate with each other. They can be mutually cooperating structures. For example, the latching groove 13 and the latching protrusion 41 can both be cylindrical, annular, prismatic, or other irregular shapes. The latching protrusion 41 can extend completely into the latching groove 13 so that the rotating plate 4 can abut against the banknote counter body 1.

[0041] Please refer to Figure 1 In addition to the voice broadcast component 2, the banknote counter for the blind in this application can also place coins on two rotating plates 4. When a group of coins is too large to be put into the coin slot 11 at once, the group of coins can be placed in the receiving slot 42 of the rotating plate 4 on the side closer to the coin slot 11, and the counted coins can be placed in the receiving slot 42 of the rotating plate 4 on the side closer to the coin outlet 12, which makes it easier for the blind to count the money. The rotating plate 4 can be rotated and locked onto the banknote counter body 1, which makes it easy to store and unfold, and easy to carry and transport the banknote counter.

[0042] In some examples, the main body 1 of the banknote counter can be set with corresponding Braille for different parts so that blind people can know the name and location of each part.

[0043] Please refer to Figure 1 In some examples, the receiving slot 42 is square, and the area of ​​the receiving slot 42 is larger than the area of ​​the coin. The larger area of ​​the receiving slot 42 makes it easier to place the coin.

[0044] In some examples, the area of ​​the receiving slot 42 can be between 1.25 and 2 times the area of ​​the coin to facilitate the insertion and removal of the coin; the number of receiving slots 42 on each rotating plate 4 can be 1, 2 or 3.

[0045] In some examples, the edges of the rotating plate 4 are rounded. The rounded corners prevent blind people from being scratched when touching it, thus improving safety.

[0046] In some examples, each edge of the rotating plate 4 can be rounded to improve the safety of the rotating plate 4.

[0047] Additionally, in some examples, a support protrusion may be formed on the side wall of the rotating plate 4 opposite to the receiving groove 42, and the support protrusion may be supported on the table so that the receiving groove 42 on the rotating plate 4 is horizontal.

[0048] Please refer to Figure 1 In some examples, the rotating plate 4 also includes a flexible layer 43, which is fixedly disposed on the snap-fit ​​protrusion 41 and pressed between the snap-fit ​​protrusion 41 and the inner wall of the snap-fit ​​groove 13. The flexible layer 43 can fix the snap-fit ​​protrusion 41 and the snap-fit ​​groove 13 relatively, thereby improving the connection stability between the snap-fit ​​protrusion 41 and the snap-fit ​​groove 13.

[0049] In some examples, the flexible layer 43 can be a rubber layer, or the snap-fit ​​protrusion 41 can be made of a flexible material so that the snap-fit ​​protrusion 41 can be tightly connected to the snap-fit ​​groove 13, which facilitates the relative stability of the rotating plate 4 and the banknote counter body 1.

[0050] In some examples, each rotating plate 4 has two locking protrusions 41, which are spaced apart along an axis parallel to the rotating shaft 3. The front and rear sides of the banknote counter body 1 each have two locking slots 13, so that each locking protrusion 41 engages within one locking slot 13. The two locking protrusions 41 and the two locking slots 13 correspond to each other, further improving the engagement stability between the banknote counter body 1 and the rotating plate 4.

[0051] In some examples, the two snap-fit ​​protrusions 41 may be located at opposite ends of the rotating plate 4, or they may be spaced apart in other ways. All the snap-fit ​​protrusions 41 may be identical.

[0052] Please refer to Figure 3 In some examples, the banknote counter for the blind also includes a counterfeit money storage area 51 and a counterfeit money plate 5. The counterfeit money plate 5 is fixedly mounted on one side wall of the banknote counter body 1 perpendicular to the front-back direction. The top of the counterfeit money plate 5 has an opening, and the counterfeit money plate 5 and the banknote counter body 1 form the counterfeit money storage area 51. The counterfeit money storage area 51 formed between the counterfeit money plate 5 and the banknote counter body 1 facilitates the storage of counterfeit money.

[0053] In some examples, the counterfeit currency plate 5 can be fixed to the banknote counter body 1 by means of adhesive, snap-fit, bolt connection, etc. The counterfeit currency plate 5 can be partially funnel-shaped, and the bottom wall of the counterfeit currency plate 5 is fixedly connected to the banknote counter body 1 to prevent the banknotes from slipping off the bottom and being lost.

[0054] The depth of the counterfeit money receiving area 51 can be greater than the width of the banknote so that the banknote can be completely placed within the counterfeit money receiving area 51.

[0055] Please refer to Figure 3 In some examples, the cross-sectional area of ​​the counterfeit coin receiving area 51 gradually increases along the height direction. This gradual increase in the cross-sectional area of ​​the counterfeit coin receiving area 51 makes it easier to insert and remove counterfeit coins.

[0056] In some examples, the side wall of the counterfeit coin plate 5 away from the banknote counter body 1 can be sloped to facilitate the removal of banknotes.

[0057] Please refer to Figure 3 In some examples, the banknote counter for the blind also includes a flexible plastic rivet 6 and a Braille writing pen 61. The flexible plastic rivet 6 is detachably mounted on the side wall of the banknote counter body 1. The flexible plastic rivet 6 and the counterfeit money receiving area 51 are located on two opposite side walls of the banknote counter body 1. The Braille writing pen 61 is hung on the flexible plastic rivet 6. The Braille writing pen 61 facilitates the blind person's recording when there are many banknotes, thus facilitating the banknote counting process.

[0058] In some examples, the resilient plastic rivet 6 may be made of nylon and typically consists of a plastic male rivet and a female rivet that expands and locks in place after installation. The resilient plastic rivet 6 may be one or more, thereby securing different parts of the Braille writing pen 61 separately.

[0059] Please return to the reference. Figure 1 and Figure 2 In some examples, the Braille writing pen 61 includes Braille paper, a Braille board, a Braille pen, and a pen cap. The Braille paper, Braille board, and Braille pen facilitate writing for blind people, and the pen cap prevents the Braille pen from pricking the user.

[0060] Braille paper is a type of paper specifically designed for blind people to write and read Braille. It is typically thicker and more durable than regular paper to withstand the pressure of the pen tip when writing Braille, while maintaining the paper's shape and preventing ink from seeping through or the paper from tearing and affecting the appearance of the Braille.

[0061] Braille paper is typically made from special acid-free paper to extend its shelf life and ensure the longevity of the Braille content. It is commonly available in A4 size or larger, with equidistant shallow dotted lines pre-printed on it. These dots serve as a positioning reference when writing Braille, helping blind people accurately press and write the raised Braille characters in the corresponding positions, thus enabling text recording and communication.

[0062] The Braille paper in this solution can be easy-tear paper, that is, the fixed part is connected to the elastic plastic rivet 6, and the rest can be torn off directly for use.

[0063] A Braille board is an important tool to help blind people write Braille. It is made of durable plastic or metal and is rectangular in shape. The board has rows of small holes that correspond to the dots pre-printed on the Braille paper. To use it, the Braille paper is laid flat on the board, and the tip of a Braille pen is aligned with the holes to press down, creating raised Braille dots on the paper.

[0064] Braille boards typically have a raised border to prevent the Braille paper from shifting during writing and to allow blind people to easily feel the paper's boundaries, ensuring the writing area remains within the paper. Some Braille boards also feature adjustable pressure levers, allowing users to adjust the pressure to suit different thicknesses of Braille paper, resulting in clearer and more regular Braille characters.

[0065] A Braille pen is a writing instrument specifically designed for writing Braille on Braille paper. Its tip is a sharp, conical shape made of a hard material that easily penetrates the Braille paper and creates clear, raised Braille dots. The pen body typically features a non-slip design, such as a textured surface or a rubber coating, to facilitate gripping by blind people and ensure stable and accurate writing.

[0066] Braille pens are carefully designed in terms of length and thickness, conforming to ergonomic principles to allow blind people to hold and write comfortably for extended periods. In addition to protecting the nib, some caps also feature Braille markings to help blind people identify the pen's type or brand.

[0067] A pen cap is an accessory that protects a Braille pen. It is generally made of a soft but resilient material, such as silicone or soft plastic. The pen cap tightly wraps around the outside of the Braille pen, preventing the pen tip from being damaged by impacts during carrying or storage, and also preventing the pen tip from puncturing the user or other objects.

[0068] Some pen caps can have special designs added to their surface, such as raised stripes or patterns, allowing blind people to identify the Braille pen by touch without opening the cap, thus improving ease of use. Pen caps are typically precisely matched to the size of the Braille pen, ensuring a snug fit that won't easily fall off, while also not interfering with the blind person's ability to hold the pen and write.

[0069] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0070] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
