Description

Technical Field

[0001] This invention relates to the field of self-service equipment and self-service terminals in the financial sector, and particularly to a device for turning pages in both directions on a passbook. Background Technology

[0002] Currently, medical, pension, and subsidy payments are disbursed through passbook accounts, and the passbook allows for real-time monitoring of deposit and withdrawal amounts. Many elderly people are accustomed to using passbooks for deposits and withdrawals, resulting in a high utilization rate. However, various banks, rural cooperatives, and other financial institutions currently require manual printing of passbook reconciliation information using a passbook reconciliation machine. Once the current page is full, the passbook needs to be ejected, and bank staff must manually flip through the pages and reinsert the passbook into the machine, which is inefficient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a passbook page turning device that enables passbook page turning. This device aims to overcome the shortcomings of existing devices in terms of functionality, effectively turning pages. Furthermore, the device is ingeniously designed and can greatly reduce the failure rate of existing page turning devices on the market, such as turning multiple pages or page turning failure.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A passbook inner page forward and reverse page turning device, comprising: an upper component and a lower component, wherein the upper component and the lower component are rotatably connected, and an entrance is provided on the side opposite to the connection between the upper component and the lower component, wherein the entrance is opened between the upper component and the lower component;

[0005] A passbook transmission channel is formed between the upper component and the lower component. The passbook transmission channel is connected to the entrance and is used to restrict the movement path of the item to be turned.

[0006] Along the passbook transmission channel in the direction away from the entrance, a primary friction wheel assembly, a page-turning wheel assembly, and a secondary friction wheel assembly are arranged in pairs and pressed together, forming the passbook transmission channel between the pressed-together primary friction wheel assembly, the page-turning wheel assembly, and the secondary friction wheel assembly; the page-turning wheel assembly is used for forward or reverse page turning.

[0007] The beneficial effects of this invention are as follows: The device can be placed in a bank lobby, allowing customers to operate it independently. When the current page of the passbook is full or the passbook inserted by the customer is not a printable page, the device can automatically flip the page and adjust to the correct page, improving efficiency, reducing error rates, minimizing human intervention, and offering wide applicability with greater market potential and application prospects. It solves the problem of slow efficiency where, after the current page of the passbook is full, bank staff must manually flip the page and reinsert the passbook into the registration machine. This makes the passbook flipping process faster and more efficient, reducing customer waiting time and improving service quality. Simultaneously, the rotating connection between the upper and lower components allows for easy opening of the upper component in case of a passbook jam, facilitating the handling of jammed passbooks, simplifying the process, and reducing equipment maintenance costs. The passbook transmission channel limits the movement path of the passbook within the flipping device.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the upper component includes: an upper housing, a page-turning shaft, and a passive friction wheel shaft, wherein the page-turning shaft and the passive friction wheel shaft are arranged parallel to each other within the upper housing along the length direction of the upper housing; a passive friction wheel is respectively provided on both sides of the page-turning shaft;

[0010] The passive friction wheel shaft on the side opposite to the connection between the upper component and the lower component is defined as the first-level passive friction wheel shaft, and the passive friction wheel shaft on the side closer to the connection between the upper component and the lower component is defined as the second-level passive friction wheel shaft.

[0011] Multiple page-turning wheels are evenly spaced on the page-turning shaft, and the multiple page-turning wheels rotate synchronously with the page-turning shaft;

[0012] Multiple primary passive friction wheels are evenly spaced on the primary passive friction wheel shaft, and the multiple primary passive friction wheels rotate synchronously with the primary passive friction wheel shaft.

[0013] Multiple secondary passive friction wheels are evenly spaced on the secondary passive friction wheel shaft, and the multiple secondary passive friction wheels rotate synchronously with the secondary passive friction wheel shaft.

[0014] The beneficial effects of adopting the above-mentioned further scheme are as follows: by driving the first-level passive friction wheel, the page-turning wheel and the second-level passive friction wheel to rotate, the first-level passive friction wheel and the second-level passive friction wheel and the passbook can move the passbook from the first-level passive friction wheel to the second-level passive friction wheel or from the second-level passive friction wheel to the first-level passive friction wheel through friction. Moreover, the first-level passive friction wheel shaft, the page-turning shaft and the second-level passive friction wheel shaft are arranged compactly, which ensures the continuity of passbook transportation.

[0015] Furthermore, the page-turning wheel includes: a base and a friction wheel rubber ring, wherein the base is sleeved on the page-turning shaft;

[0016] Hook-shaped tabs extend from both sides of the base in a direction away from the base, and the hook-shaped tabs are used to abut and hook up the inner pages of the item to be turned.

[0017] The substrate extends radially away from the substrate in an arc-shaped portion, which is disposed between the two hook pieces, and the outer wall of the arc-shaped portion is covered with the friction wheel rubber ring.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: the friction wheel rubber ring is fixed to the outer wall of the arc-shaped part, which increases the friction between the page-turning wheel and the passbook pages, making the page-turning process smoother; during the rotation of the page-turning wheel, the page hook abuts against and hooks the inner page of the item to be turned; the setting of the page hook can prevent the passbook from failing to reach the top of the page-turning wheel due to deformation or other reasons when it is turned up. The page hook hooks the end of the already turned inner page and can place it above the page-turning wheel, which can maximize the adaptability to passbooks in different storage conditions in the hands of customers and increase the success rate of page turning.

[0019] Furthermore, a page-turning passive wheel is provided on the page-turning shaft between adjacent page-turning wheels, and the outer diameter of the base at the position of the friction wheel rubber ring is greater than the outer diameter of the page-turning passive wheel, which is greater than the outer diameter of the base.

[0020] The primary passive friction wheel shaft and the secondary passive friction wheel shaft are respectively provided with pressure and folding plates, which are connected to the location where the primary passive friction wheel shaft is not provided with the primary passive friction wheel or the location where the secondary passive shaft is not provided with the secondary passive friction wheel;

[0021] The pressure plate is serrated on the side near the page-turning wheel, corresponding to the positions of the page-turning wheel and the passive page-turning wheel.

[0022] The beneficial effects of adopting the above-mentioned further solution are as follows: by arranging page-turning wheels and passive page-turning wheels at intervals on the page-turning axis, it can be ensured that the passbook pages receive a continuous and stable driving force during the page-turning process. The pressure plates, in conjunction with the page-turning wheels, facilitate the page-turning operation. The presence of two pressure plates ensures the integrity of the passbook transmission channel, flattening any upwardly deformed or warped passbook pages, allowing them to pass normally through the various friction wheel assemblies, such as the primary and secondary friction wheel assemblies, eliminating the probability of the passbook getting stuck in the transmission channel.

[0023] Furthermore, the lower assembly includes: a lower box, a passbook top plate, and a friction wheel shaft, wherein the passbook top plate and the friction wheel shaft are arranged parallel to each other within the lower box along the length direction of the lower box;

[0024] Multiple friction wheels are evenly spaced on the friction wheel shaft, and the friction wheels rotate synchronously with the friction wheel shaft; the two ends of the passbook top plate are respectively connected to the side plate of the lower box through a top plate shaft, and the passbook top plate rotates synchronously with the top plate shaft.

[0025] The beneficial effects of adopting the above-mentioned further solution are as follows: Both the top plate shaft and the friction wheel shaft are located within the lower housing and close to the upper components, ensuring a tight fit with the upper components. This also makes the entire page-turning device structure more compact, reducing unnecessary space occupation. Multiple friction wheels are evenly spaced on the friction wheel shaft, rotating synchronously with the shaft, providing a stable driving force for the passbook. A passbook top plate is installed on the top plate shaft, rotating synchronously with it. This top plate lifts the thick pages of the passbook, minimizing adhesion between the page to be turned and the pages below it. Combined with the page-turning wheels, this significantly improves the success rate of page turning and reduces the probability of turning two pages at once.

[0026] Furthermore, three friction wheel shafts are spaced apart inside the lower box, and a passbook top plate is provided on each side below the friction wheel shaft in the middle.

[0027] The friction wheel shaft on the side opposite to the connection between the upper component and the lower component is defined as the first-level friction wheel shaft, the friction wheel shaft on the side closer to the connection between the upper component and the lower component is defined as the second-level friction wheel shaft, and the friction wheel shaft located in the middle is defined as the third-level friction wheel shaft.

[0028] The top plate of the passbook is inclined downward at one end near the shaft of the third-level friction wheel and abuts against the side wall of the shaft of the third-level friction wheel. The side of the passbook top plate near the shaft of the friction wheel is hollowed out corresponding to the position of the friction wheel.

[0029] The upper end of the passbook top plate has an outward protrusion corresponding to the location where the friction wheel is not installed on the three-stage friction wheel, and multiple outward protrusions are spaced apart.

[0030] The beneficial effects of adopting the above-mentioned further solution are as follows: By driving three friction wheel shafts, the passbook can be moved smoothly from the primary friction wheel shaft to the secondary friction wheel shaft or vice versa through friction between the three friction wheel shafts and the passbook. This achieves stable driving of the passbook and effectively reduces the occurrence of jamming. Furthermore, the three friction wheel shafts are spaced apart on the side of the lower box near the upper box, resulting in a more compact layout, optimized space utilization, and ensuring the continuity of passbook transportation. The protruding part prevents the passbook from getting stuck under the tertiary friction wheel shaft during transport, even if it deforms downwards.

[0031] Furthermore, the lower component also includes: a folding cam and a folding moving shaft, wherein the folding cam is arranged perpendicular to the three-stage friction wheel shaft, the folding moving shaft is arranged below the folding cam, and the folding moving shaft is arranged parallel to the three-stage friction wheel shaft;

[0032] One end of the top-folding movable shaft extending out of the lower housing is connected to the third-stage friction wheel shaft via a top-folding frame, and the end of the third-stage friction wheel shaft is rotatably connected to the top-folding frame;

[0033] After the top-folding cam rotates, it presses down or moves away from the top-folding moving shaft, and the three-stage friction wheel shaft moves with the top-folding moving shaft through the top-folding frame.

[0034] The beneficial effects of adopting the above-mentioned further scheme are as follows: When the top-folding cam rotates from the proximal end to the distal end, the top-folding cam presses down on the top-folding moving shaft. When the top-folding cam rotates from the distal end to the proximal end, the top-folding cam moves away from the top-folding moving shaft. After the top-folding cam rotates, it presses down or moves away from the top-folding moving shaft. At this time, the three-stage friction wheel shaft moves with the top-folding moving shaft through the top-folding frame, thereby pressing down on the top plate of the passbook and changing the angle of the top plate of the passbook. This causes the thick pages of the passbook to be lifted and deformed. In the free state of being lifted, the thick pages of the passbook can minimize the adhesion between the page to be turned and the page below it, greatly improving the success rate of turning pages and reducing the probability of turning up two pages.

[0035] Furthermore, when the three-stage friction wheel shaft moves downward, the friction wheel on the three-stage friction wheel shaft presses down on one end of a pair of passbook top plates near the three-stage friction wheel shaft, and the pair of passbook top plates rotate around the top plate shaft respectively;

[0036] A torsion spring is fitted at each end of the three-stage friction wheel shaft near the lower box side plate, and the two movable ends of the torsion spring rest on the top plate shaft;

[0037] When the top folding cam rotates to the initial position, the item to be turned is transferred between the three-stage friction wheel shaft and the page-turning shaft. The torsion spring drives the three-stage friction wheel shaft to the initial position, and the pair of passbook top plates move to the initial position along with the three-stage friction wheel shaft.

[0038] The beneficial effects of adopting the above-mentioned further solution are as follows: When the three-stage friction wheel moves downward, the upper friction wheel can press down on one end of the passbook's top plate, thereby driving the passbook's top plate to rotate around the top plate axis. This ensures that the passbook can be effectively lifted and deformed during page turning, greatly reducing the adhesion between the page to be turned and the page below it, making the page turning process smoother and thus improving the success rate of page turning. Therefore, it greatly reduces the probability of turning two pages, thereby significantly improving operational efficiency. It is suitable for passbooks of different thicknesses and materials, and has strong adaptability.

[0039] Furthermore, a set of channel detection sensors is respectively provided above the upper component and below the lower component. The channel detection sensors are arranged in a one-to-one correspondence between the upper and lower components. The upper and lower channel detection sensors are respectively located on both sides of the page-turning wheel assembly and are used to detect the starting point of the passbook page turning.

[0040] A gate is also provided near the entrance. The gate is connected to the lower box body by a gate shaft provided along the length of the lower box body. A drive device is provided at one end of the gate shaft, and the gate is driven to rotate by the drive device.

[0041] A page-turning wheel sensor is also provided at the pressing and fitting point of the page-turning wheel assembly. The page-turning wheel sensor is located on the side of the lower housing corresponding to the page-turning shaft and is used to detect whether the page-turning wheel is in the initial position.

[0042] A self-reflective sensor is provided on one side of each of the pressure plates near the upper box body to detect whether the passbook has been successfully turned.

[0043] The beneficial effects of adopting the above-mentioned further solution are: the starting point of the passbook page turning is detected by the channel detection sensor; the page turning wheel sensor determines whether the page turning wheel is in the initial position; the gate opens or closes the entrance, thereby controlling whether the passbook enters the passbook transmission channel; and the self-reflection sensor determines whether the page turning is successful.

[0044] Furthermore, the first-stage passive friction wheel and the friction wheel located on the first-stage friction wheel shaft are pressed together to form the first-stage friction wheel assembly; the page-turning wheel and the friction wheel located on the third-stage friction wheel shaft are pressed together to form the page-turning wheel assembly; and the second-stage passive friction wheel and the friction wheel located on the first-stage friction wheel shaft are pressed together to form the second-stage friction wheel assembly.

[0045] The beneficial effects of adopting the above-mentioned further solution are: by cooperating with the primary friction wheel assembly, the page-turning wheel assembly, and the secondary friction wheel assembly, the passbook can be automatically turned to the correct page, improving efficiency, reducing error rate, reducing human intervention, and having wide applicability, with greater market potential and application prospects.

[0055] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0056] like Figure 1 As shown, this invention provides a passbook page turning device that allows for forward and reverse page turning. It is designed for use with bank bookkeeping machines, enabling automatic page turning of the passbook. It is conceivable that this device is not limited to automatic page turning of passbooks in bank bookkeeping machines and counter services; it can also be extended to page turning operations in self-service terminals, financial auditing, archives, teaching and research institutions, and other fields, providing efficient and convenient page turning operations for various users. Further limitations are not specified here.

[0057] Specifically, it includes an upper component 1 and a lower component 2. One end of the upper component 1 is rotatably connected to one end of the lower component 2, so that the upper component 1 can be opened when the page-turning device is jammed, making it easier to handle the jamming. At the same time, an inlet 9 is provided on the side opposite to the connection between the upper component 1 and the lower component 2. The inlet 9 is located between the upper component 1 and the lower component 2. An item to be turned is inserted into the page-turning device through the inlet 9. In this embodiment, the item to be turned is a passbook.

[0058] Specifically, a passbook transmission channel is formed between the upper component 1 and the lower component 2. The passbook transmission channel is connected to the inlet 9. Along the passbook transmission channel in the direction away from the inlet 9, a pair of pressing and cooperating primary friction wheel assembly 3, page turning wheel assembly 4 and secondary friction wheel assembly 5 are arranged sequentially. The pressing and cooperating primary friction wheel assembly 3, page turning wheel assembly 4 and secondary friction wheel assembly 5 form the passbook transmission channel.

[0059] In the actual operation, when the current page of the passbook is full or the passbook inserted by the customer is not a printable page, the passbook in the open state is entered into the page-turning device by the registration machine through the inlet 9 of the page-turning device. Driven by the first-level friction wheel assembly 3, the page-turning wheel assembly 4 and the second-level friction wheel assembly 5, it moves along the passbook transmission channel and the page-turning is completed by the rotating page-turning wheel assembly 4.

[0060] In the above solution, the device can be placed in the bank lobby, allowing customers to operate it independently. When the current page of the passbook is full or the passbook inserted by the customer is not a printable page, the device can automatically flip the page and adjust to the correct page, improving efficiency, reducing error rate, minimizing human intervention, and having wide applicability with greater market potential and application prospects. It solves the problem that currently, when the current page of the passbook is full, bank staff need to manually flip the page and insert the passbook back into the registration machine, which is inefficient. This makes the passbook flipping process faster and more efficient, reducing customer waiting time and improving service quality. At the same time, the upper component 1 and the lower component 2 are rotatably connected, so that in the event of a passbook jam, the upper component 1 can be easily opened, facilitating the handling of the jammed passbook problem, simplifying the passbook handling process, and reducing equipment maintenance costs. The passbook transmission channel limits the movement path of the passbook in the page-flipping device.

[0061] like Figure 1As shown, in a preferred embodiment, the upper component 1 includes an upper housing, a page-turning shaft 11, and a passive friction wheel shaft 12. Both the page-turning shaft 11 and the passive friction wheel shaft are housed within the upper housing. Specifically, the page-turning shaft 11 and the passive friction wheel shaft 12 are arranged parallel to each other along the length of the upper housing. To cooperate with the lower component 2, the page-turning shaft 11 and the passive friction wheel are positioned on the side of the upper housing closer to the lower component 2, and their axes are on the same horizontal plane. The page-turning shaft 11 and the passive friction wheel are rotatably connected to the side plate of the upper housing, and one end of the page-turning shaft 11 extends out of the upper housing. In this embodiment, a synchronous pulley is connected to the end of the page-turning shaft 11 extending out of the upper housing. A drive motor is also housed within the upper housing, and a synchronous pulley is also mounted on the drive motor shaft. The drive motor drives the page-turning shaft 11 to rotate via a synchronous belt.

[0062] like Figure 1-2 As shown, a passive friction wheel shaft 12 is provided on each side of the page-turning shaft 11. The passive friction wheel shaft 12 facing away from the connection between the upper component 1 and the lower component 2 is defined as the first-level passive friction wheel shaft 13, and the passive friction wheel shaft 12 closer to the connection between the upper component 1 and the lower component 2 is defined as the second-level passive friction wheel shaft 14. Specifically, multiple page-turning wheels 111 are evenly spaced on the page-turning shaft 11, and the multiple page-turning wheels 111 rotate synchronously with the page-turning shaft 11; multiple first-level passive friction wheels 131 are evenly spaced on the first-level passive friction wheel shaft 13, and the multiple first-level passive friction wheels 131 rotate synchronously with the first-level passive friction wheel shaft 13; multiple second-level passive friction wheels 141 are evenly spaced on the second-level passive friction wheel shaft 14, and the multiple second-level passive friction wheels 141 rotate synchronously with the second-level passive friction wheel shaft 14.

[0063] In the above scheme, by driving the first-stage passive friction wheel 131, the page-turning wheel 111 and the second-stage passive friction wheel 141 to rotate, the first-stage passive friction wheel 131 and the second-stage passive friction wheel 141, through friction with the passbook, can move the passbook from the first-stage passive friction wheel 131 towards the second-stage passive friction wheel 141 or from the second-stage passive friction wheel 141 towards the first-stage passive friction wheel 131. Moreover, the first-stage passive friction wheel shaft 13, the page-turning shaft 11 and the second-stage passive friction wheel shaft 14 are arranged compactly, ensuring the continuity of passbook transportation.

[0064] like Figure 3As shown, the page-turning wheel 111 includes a base 1111 and a friction wheel rubber ring 1112. The base 1111 is sleeved on the page-turning shaft 11, thereby driving the page-turning shaft 11 to rotate and thus driving the page-turning wheel 111 to rotate. The base 1111 is annular in shape, and a page-hook piece 1113 is provided on each side of the base 1111. The page-hook piece 1113 is a plate-like structure that extends from the outer wall of the base 1111 in a direction away from the base 1111. The two hook pieces 1113 on both sides are arranged collinearly, and the thickness of the hook piece 1113 gradually increases in the direction away from the base 1111, which improves the strength of the hook piece 1113; an arc-shaped part is also provided on the base 1111 between the two hook pieces 1113, so that the radii of the page turning wheels 111 on both sides of the hook piece 1113 are different. The outer wall of the arc-shaped part is covered with a friction wheel rubber ring 1112, and the arc-shaped part and the base 1111 are an integral structure.

[0065] In this embodiment, the page-turning wheel 111 consists of two parts: a base 1111 made of plastic and a friction wheel rubber ring 1112 fixed to the outer wall of the arc-shaped part, which increases the friction between the page-turning wheel 111 and the passbook pages, making the page-turning process smoother. During the rotation of the page-turning wheel 111, the page hook 1113 abuts against and hooks the inner page of the item to be turned. The page hook 1113 can prevent the passbook from not reaching the top of the page-turning wheel 111 when it is turned up due to deformation or other reasons. The page hook 1113 hooks the end of the already turned inner page and can place it above the page-turning wheel 111, which can maximize the adaptability to passbooks in different storage states in the hands of customers and increase the success rate of page turning.

[0066] like Figure 1-2 As shown, in a further embodiment, a page-turning passive wheel 112 is provided on the page-turning shaft 11 between adjacent page-turning wheels 111. In this embodiment, the page-turning passive wheel 112 is a bearing. Thus, the page-turning wheels 111 and the page-turning passive wheels 112 are spaced apart on the page-turning shaft 11. The outer diameter of the base 1111 after the friction wheel rubber ring 1112 is provided is greater than the outer diameter of the page-turning passive wheel 112, which is greater than the outer diameter of the base 1111. This ensures that when turning pages in the forward direction, the passbook moves from the first-level passive friction wheel 131 to the second-level passive friction wheel 141. During transmission, the page-turning wheel assembly 4 drives the passbook to move via the page-turning passive wheel 112. When turning pages, the page-turning wheel 111 rotates until it contacts the passbook at the location where the friction wheel rubber ring 1112 is located, thereby relying on friction to cooperate with the page hook 1113 to achieve forward page turning of the passbook. When turning pages in the opposite direction, the passbook moves in the opposite direction, and the passbook is also driven to move by the page-turning passive wheel 112. It contacts the passbook at the location where the friction wheel rubber ring 1112 is located, thereby relying on friction to cooperate with the page hook 1113 to achieve reverse page turning of the passbook.

[0067] Pressure plates 132 are respectively provided on the primary passive friction wheel shaft 13 and the secondary passive friction wheel shaft 14. Specifically, the pressure plates 132 are connected to the primary passive friction wheel shaft 13 where there is no primary passive friction wheel 131 or the secondary passive friction wheel shaft 14 where there is a secondary passive friction wheel 141. That is, the connection between the pressure plates 132 and the primary passive friction wheel shaft 13 is between adjacent primary passive friction wheels 131 and between the primary passive friction wheel 131 and the inner wall of the upper box. The connection between the pressure plates 132 and the secondary passive friction wheel shaft 14 is between adjacent secondary passive friction wheels 141 and between the secondary passive friction wheel 141 and the inner wall of the upper box. It is conceivable that a hollow part is provided on the side where the pressure plates 132 are connected to the primary passive friction wheel shaft 13 or the secondary passive friction wheel shaft 14 to avoid motion interference between the pressure plates 132 and the primary passive friction wheel 131 or the secondary passive friction wheel 141.

[0068] Similarly, to avoid motion interference between the pressure plate 132 and the page-turning roller 111 and the page-turning driven roller 112, the side of the pressure plate 132 near the page-turning roller 111 is serrated, corresponding to the positions of the page-turning roller 111 and the page-turning driven roller 112. In this embodiment, the thickness of the pressure plate 132 gradually decreases towards the page-turning axis 11.

[0069] In the above scheme, by arranging page-turning wheels 111 and page-turning passive wheels 112 at intervals on the page-turning axis 11, it can be ensured that the passbook pages can be subjected to a continuous and stable driving force during the page-turning process. The pressure plate 132, in conjunction with the page-turning wheels 111, helps to realize the page-turning operation. The presence of two pressure plates 132 can ensure the integrity of the passbook transmission channel, flattening upturned or warped passbook pages, allowing them to pass normally through each set of friction wheels 231, such as the primary friction wheel assembly 3 and the secondary friction wheel assembly 5, eliminating the probability of the passbook getting stuck in the transmission channel.

[0070] like Figure 1 As shown, in the preferred embodiment, the lower component 2 includes a lower box, a passbook top plate 211, and a friction wheel shaft 22. In order to achieve the fastening of the upper box and the lower box, a locking post is provided on each side of the upper box, and the locking post is located near the lower component 2 of the upper component 1. Correspondingly, a locking claw is provided on the lower box. By locking the locking post into the locking claw, the fastening of the upper component 1 and the lower component 2 is achieved.

[0071] like Figure 1As shown, the passbook top plate 211 and the friction wheel shaft 22 are both located inside the lower housing. Specifically, the passbook top plate 211 and the friction wheel shaft 22 are arranged parallel to each other along the length of the lower housing. To cooperate with the upper component 1, the passbook top plate 211 and the friction wheel shaft 22 are located on the side of the lower housing closer to the upper component 1. Specifically, a top plate shaft 21 passes through each end of the passbook top plate 21, connecting it to the side plate of the lower housing. The two ends of the top plate shaft 21 are fixed to the two side frames of the lower housing by bearings and can rotate relative to each other. Simultaneously, the passbook top plate 211 rotates synchronously with the top plate shaft 21. The friction wheel shaft 22 is rotatably connected to the side plate of the lower housing.

[0072] like Figure 1-2 As shown, multiple friction wheels 231 are evenly spaced on the friction wheel shaft 22, and the friction wheels 231 rotate synchronously with the friction wheel shaft 22.

[0073] In the above scheme, both the top plate shaft 21 and the friction wheel shaft 22 are located in the lower housing and close to the upper component 1, ensuring a tight fit with the upper component 1 and making the entire page-turning device structure more compact, reducing unnecessary space occupation. Multiple friction wheels 231 are evenly spaced on the friction wheel shaft 22, rotating synchronously with the friction wheel shaft 22, providing a stable driving force for the passbook. A passbook top plate 211 is set on the top plate shaft 21, rotating synchronously with the top plate shaft 21. The passbook top plate 211 lifts the thick pages 20 of the passbook, minimizing adhesion between the page to be turned and the pages below it in this free, lifted state. Combined with the page-turning wheel 111, this enables the page turning of the passbook's inner pages, greatly improving the success rate of page turning and reducing the probability of turning two pages at once.

[0074] like Figure 1-2As shown, in this embodiment, three friction wheel shafts 22 are spaced apart in the lower box. The axes of the three friction wheel shafts 22 are located on the same horizontal plane. A passbook top plate 211 is provided on both sides below the friction wheel shaft 22 in the middle. That is, in this embodiment, there are two passbook top plates 211 below the friction wheel shaft 22 in the middle. The friction wheel shaft 22 facing away from the connection between the upper component 1 and the lower component 2 is defined as the first-stage friction wheel shaft 23, the friction wheel shaft 22 closer to the connection between the upper component 1 and the lower component 2 is defined as the second-stage friction wheel shaft 24, and the friction wheel shaft 22 located in the middle is defined as the third-stage friction wheel shaft 25. One side of each of the three friction wheel shafts 22 extends out of the side plate of the lower housing. In order to drive the friction wheel shafts 22, in this embodiment, a synchronous pulley is fitted on the end of each friction wheel shaft 22 that extends out of the lower housing. The synchronous pulley on the first-stage friction wheel shaft 23 is connected to the synchronous pulley on the third-stage friction wheel shaft 25 by a synchronous belt. At the same time, the synchronous pulley on the second-stage friction wheel shaft 24 is connected to another synchronous pulley on the third-stage friction wheel shaft 25 by a synchronous belt. The other synchronous pulley on the second-stage friction wheel shaft 24 is connected to the synchronous pulley on the end of the drive motor shaft in the lower housing by a synchronous belt. The drive motor drives the first-stage friction wheel shaft 23, the second-stage friction wheel shaft 24, and the third-stage friction wheel shaft 25 to rotate.

[0075] Specifically, a pair of passbook top plates 211 are inclined downwards at one end near the third-level friction wheel shaft 25 and abut against the side wall of the third-level friction wheel shaft 25. An outward protrusion is also provided on the upper end surface of the passbook top plate 211. Multiple outward protrusions are provided at intervals corresponding to the positions on the third-level friction wheel shaft 25 where no friction wheel 231 is provided, so as to avoid motion interference with the friction wheel 231 on the third-level friction wheel shaft 25.

[0076] In the above scheme, by driving three friction wheel shafts 22, the passbook can be moved smoothly from the first-stage friction wheel shaft 23 to the second-stage friction wheel shaft 24 or from the second-stage friction wheel shaft 24 to the first-stage friction wheel shaft 23 through friction between the three friction wheel shafts 22 and the passbook. This effectively reduces the occurrence of jamming. Furthermore, the three friction wheel shafts 22 are spaced apart on the side of the lower box near the upper box, resulting in a more compact layout, optimized space utilization, and ensuring the continuity of passbook transportation. The protruding part prevents the passbook from getting stuck under the third-stage friction wheel shaft 25 during transportation, even if it deforms downwards.

[0077] like Figure 2 As shown, the lower component 2 also includes a top-bending cam 26 and a top-bending moving shaft 27. The top-bending cam 26 is arranged in a direction perpendicular to the three-stage friction wheel shaft 25, and the top-bending moving shaft 27 is arranged in a direction parallel to the three-stage friction wheel shaft 25, and the top-bending moving shaft 27 is located below the top-bending cam 26.

[0078] Specifically, one end of the top-folding movable shaft 27 extending out of the lower component 2 is connected to the third-stage friction wheel shaft 25 via the top-folding frame 28. It is conceivable that the top-folding frame 28 has connection holes for mounting the third-stage friction wheel shaft 25 and the top-folding movable shaft 27. The side plate of the lower housing also has a groove structure to facilitate the movement of the third-stage friction wheel shaft 25 and the top-folding movable shaft 27. The end of the third-stage friction wheel shaft 25 is rotatably connected to the top-folding frame 28. Specifically, the shaft end of the third-stage friction wheel shaft 25 is equipped with a bearing, which connects to the top-folding frame 28, allowing for relative rotation. Simultaneously, the top-folding frame 28 fixes the top-folding movable shaft 27 and the third-stage friction wheel shaft 25 as a single unit, allowing them to move simultaneously up and down.

[0079] In the specific operation process, when the passbook enters the page-turning device through inlet 9, the top-folding cam 26 begins to rotate 90°. That is, as the top-folding cam 26 rotates from the proximal end to the distal end, it presses down the top-folding moving shaft 27. Therefore, the rotation of the top-folding cam 26 can also simultaneously drive the three-stage friction wheel shaft 25 to move downward. The camshaft of the top-folding cam 26 can be driven to rotate by a DC motor, thereby driving the top-folding cam 26 to rotate.

[0080] When the top-folding cam 26 rotates from the proximal end to the distal end, the top-folding cam 26 presses down on the top-folding moving shaft 27. When the top-folding cam 26 rotates from the distal end to the proximal end, the top-folding cam 26 moves away from the top-folding moving shaft 27. After the top-folding cam 26 rotates and presses down or moves away from the top-folding moving shaft 27, the three-stage friction wheel shaft 25 moves with the top-folding moving shaft 27 through the top-folding frame 28, thereby pressing down on the passbook top plate 211 and changing the angle of the passbook top plate 211. This causes the passbook thick page 20 to be lifted and deformed. In the free state of being lifted, the passbook thick page 20 can minimize the adhesion between the page to be turned and the page below it, greatly improving the success rate of turning pages and reducing the probability of turning up two pages.

[0081] like Figure 2 As shown, when the third-stage friction wheel shaft 25 moves downward, the third-stage friction wheel shaft 25 presses down on one end of a pair of passbook top plates 211 near the third-stage friction wheel 231, thereby causing the pair of passbook top plates 211 to rotate around the top plate shaft 21 respectively, ultimately forming Figure 5 In this position, the passbook's thick page 20 is lifted and deformed, losing the clamping force of the page-turning passive wheel 112 on the three-stage friction wheel shaft 25 and the page-turning shaft 11, becoming a free state. In this lifted, free state, the thick page 20 minimizes adhesion between the page to be turned and the page below it. Furthermore, experiments have shown that this structure and setting significantly improves the success rate of page turning and reduces the probability of turning two pages. Specifically, when the passbook is open, the thick page 20 is defined as the passbook's inner pages, including the page to be turned and the inner pages below it.

[0082] To achieve the reset of the three-stage friction wheel shaft 25, a torsion spring is fitted at each end of the three-stage friction wheel shaft 25 near the lower side panel of the box. The torsion spring has two protruding movable ends, which rest on the top plate shaft 21. When the top folding cam 26 rotates to its initial position, the top folding cam 26 is not in contact with the top folding moving shaft 27 in the initial position. After the page-turning item is transferred between the three-stage friction wheel shaft 25 and the page-turning shaft 11, the torsion spring drives the three-stage friction wheel shaft 25 to its initial position. At the same time, the pair of passbook top plates 211 rotate around the top plate shaft 21 to their initial position under the action of gravity. In this embodiment, the initial position of the top-folding cam 26 is when the proximal end of the top-folding cam 26 is closest to the top-folding moving shaft 27; the initial position of the third-stage friction wheel shaft 25 is the position where the friction wheel rubber ring 1112 on the friction wheel 231 faces upward; the initial position of the third-stage friction wheel shaft 25 is the position it is in when it is not moved downward by the top-folding frame 28.

[0083] In the above scheme, when the three-stage friction wheel shaft 25 moves downward, the friction wheel 231 on it can press down on one end of the passbook top plate 211, thereby driving the passbook top plate 211 to rotate around the top plate shaft 21. This ensures that the passbook can be effectively lifted and deformed during page turning, greatly reducing the adhesion between the page to be turned and the page below it, making the page turning process smoother and thus improving the success rate of page turning. Therefore, the probability of turning two pages is greatly reduced, thereby significantly improving operational efficiency. It is suitable for passbooks of different thicknesses and materials, and has strong adaptability.

[0084] like Figure 1 , Figure 4 As shown, a set of channel detection sensors 6 are respectively arranged above the upper component 1 and below the lower component 2. The channel detection sensors 6 are arranged in a one-to-one correspondence, with the upper and lower channel detection sensors 6 located on both sides of the page-turning wheel assembly 4. In some feasible embodiments, the channel detection sensors 6 are through-beam photoelectric sensors used to detect the starting point of the passbook page turning. When turning pages forward, the passbook transmits data to the sensor... Figure 4 At the position shown, the pair of upper and lower channel detection sensors 6 on the side near the secondary friction wheel assembly 5 are blocked by the passbook and cannot receive signals, and the passbook is in the position to be turned.

[0085] A gate 7 is also installed near the entrance 9. The gate 7 is connected to the lower housing via a gate shaft that runs along the length of the lower housing. A drive device is installed on one side of the gate 7. The drive device drives the gate 7 to rotate, thereby opening or closing the entrance 9 and controlling the entry of the passbook into the passbook transmission channel. In some feasible embodiments, the drive device is an electric actuator. An "L"-shaped frame is installed at the end of the gate shaft. When the passbook needs to be turned, the gate 7 is in a horizontal position, and the passbook can enter the passbook transmission channel through the entrance 9. When the passbook does not need to be turned, the electric actuator pushes the "L"-shaped frame, thereby driving the gate shaft to rotate. The gate 7 is raised to close the entrance 9, and the passbook does not enter the passbook transmission channel. In this case, it is not necessary to drive the primary friction wheel assembly 3, the page-turning wheel assembly 4, and the secondary friction wheel assembly 5 to rotate. It is conceivable that the gate 7 can be driven by, but is not limited to, an electric actuator. Other methods that can achieve the rotation of the gate 7 are also acceptable, and no further limitations are made here.

[0086] A page-turning wheel sensor 8 is also provided at the clamping engagement point of the page-turning wheel assembly 4. The page-turning wheel sensor 8 is located on one side of the lower housing corresponding to the page-turning shaft 11. In this embodiment, the page-turning wheel sensor 8 is an infrared self-reflection sensor 15. A detection plate is provided at the end of one side of the page-turning shaft 11. The detection plate is located at the center of the end of the page-turning shaft 11 and extends outward with a long end. The detection plate rotates with the page-turning shaft 11. When the long end rotates out of the position of the page-turning wheel sensor 8, the page-turning wheel sensor 8 cannot detect the long end. When the long end rotates to the position of the page-turning wheel sensor 8, the long end can be detected by the page-turning wheel sensor 8. This position can be set as the initial position of the page-turning wheel 111. At this position, the position of the friction wheel rubber ring 1112 of the page-turning wheel 111 is located at the top. The page-turning wheel sensor 8 determines whether the page-turning wheel 111 is in the initial position. Each time the page-turning action is completed, the page-turning wheel 111 is rotated to the initial position.

[0087] like Figure 4As shown, self-reflective sensors 15 are respectively provided on one side of a pair of pressure plates 132 near the upper housing, that is, the self-reflective sensors 15 are fixed above the pressure plates 132. In some feasible embodiments, the self-reflective sensors 15 are infrared self-reflective sensors 15. When the passbook enters the passbook transmission channel, it can be detected. When the inner pages of the passbook push up the pressure plates 132, the self-reflective sensors 15 cannot detect the item. As the deformation of the inner pages of the passbook increases, the self-reflective sensors 15 detect the item again. That is, if the passbook is always detected in the passbook transmission channel, it proves that the inner pages of the passbook have not been lifted by the top plate 211. If the self-reflective sensors 15 detect something after not detecting it, it proves that the soft pages have not been lifted. If something is detected again after not detecting it, it proves that the passbook has been successfully turned. In the specific operation, when the hook 1113 hooks up the end of the flipped inner page and places it above the page turning wheel 111, the self-reflection sensor 15 on the pressure plate 132 can detect the flipped inner page of the passbook, thus determining that the page turning is successful.

[0088] In the above scheme, the starting point of the passbook page turning is detected by the channel detection sensor 6; the page turning wheel sensor 8 determines whether the page turning wheel 111 is in the initial position; the gate 7 opens or closes the entrance 9 to control whether the passbook enters the passbook transmission channel; and the self-reflection sensor 15 determines whether the page turning is successful.

[0089] In this embodiment, the first-stage passive friction wheel 131 and the friction wheel 231 located on the first-stage friction wheel shaft 23 are pressed together to form the first-stage friction wheel assembly 3. The page-turning wheel 111 and the page-turning passive wheel 112 and the friction wheel 231 located on the third-stage friction wheel shaft 25 are pressed together to form the page-turning wheel assembly 4. The second-stage passive friction wheel 141 and the friction wheel 231 located on the first-stage friction wheel shaft 23 are pressed together to form the second-stage friction wheel assembly 5.

[0090] In the above solution, the primary friction wheel assembly 3, the page-turning wheel assembly 4, and the secondary friction wheel assembly 5 work together to achieve automatic page turning of the passbook, adjusting it to the correct page, improving efficiency, reducing error rate, reducing human intervention, and having wide applicability, with greater market potential and application prospects.

[0091] The specific working process is as follows: In the initial state, the positions of all components of the page-turning device are as follows: Figure 4 As shown, the passbook enters through entrance 9 of the page-turning device at the passbook counter, and stops at the channel detection sensor 6. Figure 4 At the position shown, the passbook cover 10 extends through the opening in the upper box; then Figure 2The top-folding cam 26 begins to rotate 90°, pressing down the top-folding moving shaft 27. The rotation of the top-folding cam 26 also simultaneously drives the intermediate friction wheel shaft 22 to move downwards. As the intermediate friction wheel shaft 22 moves downwards, it drives the two passbook top plates 211 to rotate around the top plate shaft 21, ultimately forming... Figure 5 The passbook's thick page 20 is now in a free state. At this point, the thick page 20 is lifted and deformed, and loses the clamping of the intermediate friction wheel 231 and the bearing on the page-turning shaft 11.

[0092] With the page-turning wheel 111 in place, when the end of the passbook's thick page 20 is transferred between the page-turning shaft 11 and the secondary passive friction wheel shaft 14, the page-turning shaft 11 rotates clockwise, driving the page-turning wheel 111 to rotate. Since the page-turning wheel 111 and the page-turning shaft 11 are relatively fixed, they rotate synchronously. The friction wheel rubber ring 1112 of the page-turning wheel 111 begins to turn the inner page to be turned through friction. As the turned inner page warps upward, it pushes up the pressure plate 132. When the page-turning wheel 111 rotates to... Figure 5 When the page is in the position shown, the flipped inner page 30 is positioned precisely at the hook 1113 of the page-turning wheel 111. As the page-turning wheel 111 continues to rotate, the hook 1113 hooks the end of the flipped inner page, placing it above the page-turning wheel 111. At this time, the self-reflective sensor 15 on the folding plate 132 can detect the flipped inner page of the passbook, thus determining that the page turning was successful. After the page-turning wheel 111 completes one revolution, it returns to its initial position, as shown. Figure 6 The page turning is complete. At this point, the top folding cam 26 rotates in the opposite direction to return to its initial position, and the passbook returns to the clamping state of the three-stage friction wheel 231 and the page-turning passive wheel 112. Simultaneously, the passbook top plate 211 also returns to its initial position. Figure 6 As shown. Driven by the primary friction wheel assembly 3 and the secondary friction wheel assembly 5, the passbook moves towards the entrance 9. The flipped inner pages are smoothed out by the page-turning passive wheel 112 on the page-turning shaft 11 as it moves forward, completing the entire flipping action.

[0093] If the OCR (Optical Character Recognition) page recognition system determines that the passbook has two pages flipped, the passbook will return to the page-turning device from entrance 9 and stop at the position shown in the figure, completing the reverse page turn by mirroring the previous page turn. Figure 7 .

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
