Many elderly people are accustomed to using passbooks to deposit and withdraw money, so the utilization rate of passbooks is still very high. However, various banks, rural cooperatives and other financial enterprises currently need to use passbook re-boarding to manually print passbook reconciliation information when handling passbook business. After the current page of the passbook is filled with content, the passbook needs to be exited, and the bank staff manually turns the page and inserts the passbook again for re-boarding, which is inefficient.

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

[0014] The beneficial effect of adopting the above further scheme is: 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, the second-level passive friction wheel and the passbook drive the passbook to move 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, and the first-level passive friction wheel axle, the page-turning axle and the second-level passive friction wheel axle are arranged compactly, thereby ensuring the continuity of passbook transportation.

[0016] Page hook pieces extend from both sides of the base body in a direction away from the base body, and the page hook pieces are used to abut against and hook the inner pages of the article to be turned;

[0017] The base body extends an arc-shaped portion in a radial direction away from the base body, the arc-shaped portion is arranged 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 further scheme are: the rubber ring of the friction wheel is fixed to the outer wall of the arc-shaped part, which increases the friction between the page-turning wheel and the pages of the passbook, making the page-turning process smoother; during the rotation of the page-turning wheel, the page-hooking piece abuts against the inner page to be turned over and hooks up the inner page of the object to be turned over; the setting of the page-hooking piece can prevent the passbook from being unable to reach the top of the page-turning wheel due to deformation and other reasons when it is turned over. The page-hooking piece hooks up the tail end of the turned inner page and can place it above the page-turning wheel, which can adapt to the passbooks in different storage states in the hands of customers to the greatest extent and increase the success rate of page turning.

[0019] Furthermore, a page turning passive wheel is arranged on the page turning shaft between the adjacent page turning wheels, and the outer diameter of the base body where the friction wheel rubber ring is arranged>the outer diameter of the page turning passive wheel>the outer diameter of the base body;

[0020] The first-level passive friction wheel shaft and the second-level passive friction wheel shaft are also provided with a folding plate, respectively, and the folding plate is connected to the first-level passive friction wheel shaft where the first-level passive friction wheel is not provided or the second-level passive shaft where the second-level passive friction wheel is not provided;

[0021] The side of the folding plate close to the page turning wheel is arranged in a sawtooth shape corresponding to the position of the page turning wheel and the page turning passive wheel.

[0022] The beneficial effect of adopting the above further scheme is that by arranging the page turning wheel and the passive page turning wheel at intervals on the page turning shaft, it can be ensured that the pages of the passbook can be subjected to continuous and stable driving force during the page turning process. The folding plate and the page turning wheel are helpful to realize the page turning operation. The existence of the two folding plates can ensure the integrity of the passbook transmission channel, flatten the passbook pages that are deformed or tilted upward, so that they can pass through each group of friction wheels normally, such as the primary friction wheel assembly and the secondary friction wheel assembly, eliminating the probability of the passbook being stuck and folded in the transmission channel.

[0023] Further, the lower assembly comprises: a lower box, a passbook top plate and a friction wheel shaft, wherein the passbook top plate and the friction wheel shaft are arranged in parallel with each other in the lower box along the length direction of the lower box;

[0025] The beneficial effects of adopting the above further scheme are as follows: the top plate shaft and the friction wheel shaft are both arranged in the lower box body and are arranged close to the upper component, ensuring a close fit with the upper component, while making the entire page turning device structure more compact and reducing unnecessary space occupation; multiple friction wheels are evenly spaced on the friction wheel shaft, and the friction wheels rotate synchronously with the friction wheel shaft, providing a stable driving force for the passbook. A passbook top plate is arranged on the top plate shaft, and the passbook top plate rotates synchronously with the top plate shaft. The passbook top plate is used to lift the thick pages of the passbook, so that the thick pages of the passbook can minimize the adhesion between the pages to be turned and the pages below them in such a lifted free state, and the page turning wheel is used to realize the page turning of the inner pages of the passbook, which greatly improves the success rate of page turning and reduces the probability of turning double pages.

[0026] Furthermore, three friction axles are arranged at intervals in the lower box body, and a passbook top plate is respectively arranged on both sides below the friction axle in the middle;

[0027] The friction axle on the side away from the connection between the upper component and the lower component is defined as a primary friction axle, the friction axle on the side close to the connection between the upper component and the lower component is defined as a secondary friction axle, and the friction axle in the middle is defined as a tertiary friction axle;

[0028] One end of a pair of passbook top plates close to the three-stage friction wheel shaft is tilted downward and abuts against the side wall of the three-stage friction wheel shaft, and one side of the passbook top plate close to the friction wheel shaft is hollowed out corresponding to the position of the friction wheel;

[0029] An outer convex portion is protrudingly provided on the upper end surface of the top plate of the passbook corresponding to the position where the third-stage friction wheel is not provided with the friction wheel, and a plurality of the outer convex portions are provided at intervals.

[0030] The beneficial effects of adopting the above further scheme are: by driving the three friction axles, the three friction axles and the passbook can be driven by friction to move the passbook from the primary friction axle to the secondary friction axle or from the secondary friction axle to the primary friction axle, so that the passbook can be driven smoothly, and the occurrence of jamming and folding can be effectively reduced; and the three friction axles are arranged at intervals on the side of the lower box body close to the upper box body, the layout is more compact, the space utilization is optimized, and the continuity of the passbook transportation is ensured. The setting of the outer convex part ensures that during the transmission of the passbook, even if the passbook is deformed downward, the outer convex part will block it and prevent the passbook from entering under the third friction axle and causing jamming and folding.

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

[0033] The top-folding cam is rotated to press down or move 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 effect of adopting the above further scheme is: when the top folding cam rotates from the proximal end to the distal end, the top folding cam presses down the top folding moving shaft, and when the top folding cam rotates from the distal end to the proximal end, the top folding cam deviates 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-level friction wheel shaft moves with the top folding moving shaft through the top folding frame, thereby realizing the downward pressure on the top plate of the passbook, changing the angle of the top plate of the passbook, so that the thick pages of the passbook are lifted up and deformed. The thick pages of the passbook can minimize the adhesion between the pages to be turned over and the pages below them in the lifted free state, which greatly improves the success rate of page turning and reduces the probability of turning over double pages.

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

[0036] A torsion spring is sleeved on both ends of the three-stage friction wheel shaft close to the side plate of the lower box body, and two movable ends of the torsion spring are placed on the top plate shaft;

[0037] When the top folding cam rotates to the initial position, the items to be turned are 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 a pair of passbook top plates move to the initial position along with the three-stage friction wheel shaft.

[0038] The beneficial effect of adopting the above further scheme is that when the three-stage friction wheel axis moves downward, the friction wheel thereon can press down one end of the top plate of the passbook, thereby driving the top plate of the passbook to rotate around the top plate axis, ensuring that the passbook can be effectively lifted up and deformed during the page turning process, so that the adhesion between the page to be turned up and the page below it is greatly reduced, making the page turning process smoother, thereby improving the success rate of page turning. Therefore, the probability of turning over two pages is greatly reduced, thereby significantly improving the operating efficiency. It is suitable for passbooks of different thicknesses and materials and has strong adaptability.

[0039] Furthermore, a group of channel detection sensors are respectively arranged above the upper component and below the lower component. The channel detection sensors are arranged one by one above and below, and the channel detection sensors located above and below are respectively located on both sides of the page turning wheel component, for detecting the starting point of turning the pages of the passbook;

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

[0041] A page-turning wheel sensor is also provided at the compression fit corresponding to the page-turning wheel assembly. The page-turning wheel sensor is provided on one side of the lower box body corresponding to the page-turning shaft, and is used to detect whether the page-turning wheel is located at an initial position;

[0042] A self-reflection sensor is respectively arranged on one side of a pair of folding plates close to the upper box body, for detecting whether the page of the passbook is turned successfully.

[0043] The beneficial effects of adopting the above further scheme are: detecting the starting point of turning the pages of the passbook by means of the channel detection sensor; judging whether the page turning wheel is located at the initial position by means of the page turning wheel sensor; opening or closing the entrance by means of the gate, thereby controlling whether the passbook enters the passbook transmission channel; judging whether the page turning is successful by means of the self-reflection sensor.

[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 effect of adopting the above further scheme is: through the cooperation of 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, the passbook can be adjusted to the correct page, the efficiency can be improved, the error rate can be reduced, human intervention can be reduced, and it has wide applicability and greater market potential and application prospects.

DETAILED DESCRIPTION

[0055] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0056] like Figure 1 As shown, the utility model provides a device for turning pages of the inner pages of a passbook in both positive and negative directions, which is used in conjunction with the bank's supplementary boarding service, and the passbook is automatically turned through the page turning device; it can be imagined that this page turning device is not limited to the automatic page turning of the passbook for bank supplementary boarding and counter services, but can also be expanded to the page turning operations of other items in multiple fields such as self-service terminals, financial audits, archives, teaching and research institutions, etc., to provide efficient and convenient page turning operations for various users, and no further limitations are made here.

[0057] Specifically, it comprises: 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 when the page turning device is folded, the upper component 1 can be opened to facilitate the handling of the folding. At the same time, an entrance 9 is also provided on the side away from the connection between the upper component 1 and the lower component 2, and the entrance 9 is opened between the upper component 1 and the lower component 2. The object to be turned is inserted into the page turning device through the entrance 9. In this embodiment, the object to be turned is a passbook.

[0058] Specifically, a passbook transmission channel is formed between the upper component 1 and the lower component 2, and the passbook transmission channel is connected to the entrance 9. A first-level friction wheel assembly 3, a page-turning wheel assembly 4 and a second-level friction wheel assembly 5 that are tightly fitted are sequentially arranged in pairs along the passbook transmission channel in a direction away from the entrance 9, and a passbook transmission channel is formed between the first-level friction wheel assemblies 3, the page-turning wheel assemblies 4 and the second-level friction wheel assemblies 5 that are tightly fitted.

[0059] In the specific working process, when the current page of the passbook is fully printed or the passbook inserted by the customer is not a printable page, the passbook in the open state enters the page turning device through the entrance 9 of the page turning device from the supplementary boarding machine, and moves along the passbook transmission channel driven by the primary friction wheel assembly 3, the page turning wheel assembly 4 and the secondary friction wheel assembly 5, and completes the page turning of the passbook by rotating the page turning wheel assembly 4.

[0060] In the above scheme, the device can be placed in the bank hall and the customer can 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 turn the page and adjust to the correct page, thereby improving efficiency, reducing error rate, reducing human intervention, and having wide applicability, greater market potential and application prospects. It solves the problem that the current passbook needs to be exited after the current page is full, and bank staff manually turn the page and insert the passbook again for boarding, which is inefficient. It makes the passbook page turning process faster and more efficient, reduces customer waiting time, and improves service quality. At the same time, the upper component 1 and the lower component 2 are rotatably connected, so that when a jam occurs, the upper component 1 can be easily opened, which is convenient for handling the jam problem, simplifies the jam handling process, and reduces the maintenance cost of the equipment. The moving path of the passbook in the page turning device is limited by the passbook transmission channel.

[0061] like Figure 1As shown, in the preferred solution, the upper component 1 includes: an upper housing, a page-turning shaft 11 and a passive friction wheel shaft 12. The page-turning shaft 11 and the passive friction wheel shaft 12 are both arranged in the upper housing. Specifically, the page-turning shaft 11 and the passive friction wheel shaft 12 are arranged along the length direction of the upper housing and parallel to each other. At the same time, in order to cooperate with the lower component 2, the page-turning shaft 11 and the passive friction wheel are arranged on the side of the upper housing close to the lower component 2, and the axis of the page-turning shaft 11 and the passive friction wheel are located 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, the end of the page-turning shaft 11 extending out of the upper housing is connected to a synchronous pulley. At the same time, a driving motor is also arranged in the upper housing, and a synchronous pulley is also arranged on the driving motor shaft. The driving motor drives the page-turning shaft 11 to rotate through a synchronous belt.

[0062] like Figure 1-2 As shown, a passive friction wheel shaft 12 is respectively arranged on both sides of the page turning shaft 11, and the passive friction wheel shaft 12 away from the side where the upper component 1 and the lower component 2 are connected is defined as the primary passive friction wheel shaft 13, and the passive friction wheel shaft 12 close to the side where the upper component 1 and the lower component 2 are connected is defined as the secondary passive friction wheel shaft 14. Specifically, a plurality of page turning wheels 111 are evenly spaced on the page turning shaft 11, and the plurality of page turning wheels 111 rotate synchronously with the page turning shaft 11; a plurality of primary passive friction wheels 131 are evenly spaced on the primary passive friction wheel shaft 13, and the plurality of primary passive friction wheels 131 rotate synchronously with the primary passive friction wheel shaft 13; a plurality of secondary passive friction wheels 141 are evenly spaced on the secondary passive friction wheel shaft 14, and the plurality of secondary passive friction wheels 141 rotate synchronously with the secondary passive friction wheel shaft 14.

[0063] In the above scheme, by driving the primary passive friction wheel 131, the page turning wheel 111 and the secondary passive friction wheel 141 to rotate, the primary passive friction wheel 131 and the secondary passive friction wheel 141 drive the passbook through friction, so that the passbook can be moved from the primary passive friction wheel 131 to the secondary passive friction wheel 141 or from the secondary passive friction wheel 141 to the primary passive friction wheel 131, and the primary passive friction wheel shaft 13, the page turning shaft 11 and the secondary passive friction wheel shaft 14 are arranged compactly, thereby ensuring the continuity of the 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, so as to realize driving the page turning shaft 11 to rotate and drive the page turning wheel 111 to rotate; the base 1111 is annular, and a page hook piece 1113 is arranged on both sides of the base 1111. The page hook piece 1113 is a plate-like structure extending from the outer wall of the base 1111 in a direction away from the base 1111, and is located on the base 1111. The two hook pieces 1113 on both sides are arranged in a colinear manner, wherein the thickness of the hook piece 1113 gradually increases in the direction away from the base 1111, thereby improving the strength of the hook piece 1113; an arc portion is also arranged 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, and the outer wall of the arc portion is covered with a friction wheel rubber ring 1112, wherein the arc portion and the base 1111 are an integrated structure.

[0065] In this embodiment, the page turning wheel 111 is composed of two parts. The base 1111 adopts a plastic base 1111, and the friction wheel rubber ring 1112 is fixed to the outer wall of the arc portion, which increases the friction between the page turning wheel 111 and the pages of the passbook, making the page turning process smoother; during the rotation of the page turning wheel 111, the page hook piece 1113 abuts against the inner page to be turned and hooks up the inner page of the object to be turned over; the setting of the page hook piece 1113 can prevent the passbook from being unable to reach the top of the page turning wheel 111 due to deformation and other reasons when it is turned over. The page hook piece 1113 hooks up the tail end of the turned inner page and can place it above the page turning wheel 111, which can adapt to the passbooks in different storage states in the hands of customers to the greatest extent and increase the success rate of page turning.

[0066] like Figure 1-2 As shown, in a further solution, a page-turning passive wheel 112 is arranged on the page-turning shaft 11 between adjacent page-turning wheels 111. In this embodiment, the page-turning passive wheel 112 adopts a bearing, so that the page-turning wheel 111 and the page-turning passive wheel 112 are arranged on the page-turning shaft 11 at intervals, and the outer diameter of the base 1111 after the friction wheel rubber ring 1112 is arranged is greater than the outer diameter of the page-turning passive wheel 112> the outer diameter of the base 1111, so that when the page is turned in the forward direction, the passbook is turned from the primary passive friction wheel 131 to the secondary 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 to the point where the friction wheel rubber ring 1112 is provided to contact the passbook, thereby relying on the friction force in conjunction with the page hook piece 1113 to achieve forward page turning of the passbook; when turning pages in the reverse direction, the passbook moves in the opposite direction, and the passbook is also driven to move by the page turning passive wheel 112, contacting the passbook via the friction wheel rubber ring 1112, thereby relying on the friction force in conjunction with the page hook piece 1113 to achieve reverse page turning of the passbook.

[0067] A folding plate 132 is also provided on the primary passive friction wheel shaft 13 and the secondary passive friction wheel shaft 14, respectively. Specifically, the folding plate 132 is connected to the primary passive friction wheel shaft 13 where the primary passive friction wheel 131 is not provided or to the secondary passive friction wheel shaft 14 where the secondary passive friction wheel 141 is provided, that is, the connection between adjacent primary passive friction wheels 131 and between the primary passive friction wheel 131 and the inner wall of the upper box is the connection between the folding plate 132 and the primary passive friction wheel shaft 13, and the connection between adjacent secondary passive friction wheels 141 and between the secondary passive friction wheel 141 and the inner wall of the upper box is the connection between the folding plate 132 and the secondary passive friction wheel shaft 14; it can be imagined that a hollow portion is provided on the side where the folding plate 132 is connected to the primary passive friction wheel shaft 13 or the secondary passive friction wheel shaft 14 to avoid motion interference between the folding plate 132 and the primary passive friction wheel 131 or the secondary passive friction wheel 141.

[0068] Similarly, in order to avoid motion interference between the folding plate 132 and the page turning wheel 111 and the page turning passive wheel 112, the folding plate 132 is arranged in a sawtooth shape at the side close to the page turning wheel 111 corresponding to the page turning wheel 111 and the page turning passive wheel 112. In this embodiment, the thickness of the folding plate 132 gradually decreases towards the page turning shaft 11.

[0069] In the above scheme, by arranging the page turning wheel 111 and the page turning passive wheel 112 at intervals on the page turning shaft 11, it can be ensured that the pages of the passbook can be subjected to continuous and stable driving force during the page turning process. The folding plate 132 cooperates with the page turning wheel 111 to help realize the page turning operation. The existence of the two folding plates 132 can ensure the integrity of the passbook transmission channel, flatten the passbook pages that are deformed or tilted upward, so that they can pass through each group of friction wheels 231 normally, such as: the primary friction wheel assembly 3 and the secondary friction wheel assembly 5, eliminating the probability of the passbook being stuck and folded in the transmission channel.

[0070] like Figure 1 As shown, in the preferred scheme, the lower component 2 includes: a lower box body, a passbook top plate 211 and a friction wheel shaft 22. In order to achieve the snap fit between the upper box body and the lower box body, a clamping column is respectively provided on both sides of the upper box body, and the clamping column is provided on the upper component 1 close to the lower component 2. Correspondingly, a claw is provided on the lower box body. The clamping column can be snapped into the claw to achieve the snap fit between the upper component 1 and the lower component 2.

[0071] like Figure 1As shown, the top plate 211 of the passbook and the friction wheel shaft 22 are both arranged in the lower box body. Specifically, the top plate 211 of the passbook and the friction wheel shaft 22 are arranged along the length direction of the lower box body and parallel to each other. At the same time, in order to cooperate with the upper component 1, the top plate 211 of the passbook and the friction wheel shaft 22 are arranged on the side of the lower box body close to the upper component 1; specifically, a top plate shaft 21 is respectively passed through the two ends of the top plate 211 of the passbook, and is connected to the side plate of the lower box body through the top plate shaft 21. The two ends of the top plate shaft 21 are fixed to the two side frames of the lower box body through bearings and can rotate relatively. At the same time, the top plate 211 of the passbook rotates synchronously with the top plate shaft 21. The friction wheel shaft 22 is rotatably connected to the side plate of the lower box body.

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

[0073] In the above scheme, the top plate shaft 21 and the friction wheel shaft 22 are both arranged in the lower box body and are arranged close to the upper component 1, ensuring a close fit with the upper component 1, while making the entire page turning device structure more compact and reducing unnecessary space occupation; 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, providing a stable driving force for the passbook. A passbook top plate 211 is arranged on the top plate shaft 21, and the passbook top plate 211 rotates synchronously with the top plate shaft 21. The passbook top plate 211 lifts the passbook thick page 20, so that the passbook thick page 20 can minimize the adhesion between the page to be turned and the page below it in such a lifted free state, and cooperates with the page turning wheel 111 to realize the page turning of the inner page of the passbook, which greatly improves the success rate of page turning and reduces the probability of turning double pages.

[0074] like Figure 1-2As shown, in the present embodiment, three friction wheel axles 22 are arranged at intervals in the lower box body, the axes of the three friction wheel axles 22 are located on the same horizontal plane, and a passbook top plate 211 is respectively arranged on both sides below the middle friction wheel axle 22, that is, in the present embodiment, there are two passbook top plates 211 below the middle friction wheel axle 22. The friction wheel shaft 22 that is away from the side where the upper component 1 and the lower component 2 are connected is defined as the primary friction wheel shaft 23, the friction wheel shaft 22 that is close to the side where the upper component 1 and the lower component 2 are connected is defined as the secondary friction wheel shaft 24, and the friction wheel shaft 22 located in the middle is defined as the tertiary friction wheel shaft 25; one side of the three friction wheel shafts 22 all extend out of the side plate of the lower box body. In order to drive the friction wheel shafts 22, in this embodiment, the end of each friction wheel shaft 22 extending out of the lower box body is sleeved with a synchronous pulley, and the synchronous pulley on the primary friction wheel shaft 23 is connected to the synchronous pulley on the tertiary friction wheel shaft 25 through a synchronous belt, and at the same time, the synchronous pulley on the secondary friction wheel shaft 24 is connected to another synchronous pulley on the tertiary friction wheel shaft 25 through a synchronous belt, and another synchronous pulley on the secondary friction wheel shaft 24 is connected to the synchronous pulley at the shaft end of the driving motor in the lower box body through a synchronous belt, and the primary friction wheel shaft 23, the secondary friction wheel shaft 24 and the tertiary friction wheel shaft 25 are driven to rotate by the driving motor.

[0075] Specifically, a pair of passbook top plates 211 are arranged at an angle downward near one end of the tertiary friction wheel shaft 25 and abut against the side wall of the tertiary friction wheel shaft 25. An outer convex portion is also arranged on the upper end surface of the passbook top plate 211. A plurality of outer convex portions are arranged at intervals corresponding to positions on the tertiary friction wheel shaft 25 where no friction wheel 231 is arranged, so as to avoid motion interference with the friction wheel 231 on the tertiary friction wheel shaft 25.

[0076] In the above scheme, by driving the three friction axles 22, the three friction axles 22 and the passbook can be driven by friction to move the passbook from the primary friction axle 23 to the secondary friction axle 24 or from the secondary friction axle 24 to the primary friction axle 23, so as to achieve a smooth drive of the passbook and effectively reduce the occurrence of jamming and folding. The three friction axles 22 are arranged at intervals on the side of the lower box body close to the upper box body, and the layout is more compact, optimizing the space utilization and ensuring the continuity of the passbook transportation. The setting of the convex part ensures that even if the passbook is deformed downward during the transmission process, the convex part will prevent the passbook from entering the lower part of the third friction axle 25 and causing jamming and folding.

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

[0078] Specifically, one end of the top-folding movable shaft 27 extending out of the lower component 2 is connected to the tertiary friction wheel shaft 25 through the top-folding frame 28. It can be imagined that connecting holes for installing the tertiary friction wheel shaft 25 and the top-folding movable shaft 27 are respectively provided on the top-folding frame 28, and a groove structure is also provided on the side panel of the lower box body to facilitate the movement of the tertiary friction wheel shaft 25 and the top-folding movable shaft 27, and the end of the tertiary friction wheel shaft 25 is rotatably connected to the top-folding frame 28; specifically, the shaft end of the tertiary friction wheel shaft 25 is provided with a bearing, which is connected to the top-folding frame 28 through the bearing and can rotate relative to each other; at the same time, the top-folding frame 28 fixes the top-folding movable shaft 27 and the tertiary friction wheel shaft 25 as a whole, so that they can be the same above and below.

[0079] In a specific working process, when the passbook enters the page turning device through the entrance 9, the top folding cam 26 starts to rotate 90°, that is, the top folding cam 26 rotates from the proximal end to the distal end, pressing down the top folding moving shaft 27. Therefore, the rotation of the top folding cam 26 can also drive the three-stage friction wheel shaft 25 to move downward. The cam shaft 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 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. The top folding cam 26 rotates to press down or move away from the top folding moving shaft 27. At this time, the three-level friction wheel shaft 25 moves with the top folding moving shaft 27 through the top folding frame 28, thereby realizing the downward pressure on the passbook top plate 211, changing the angle of the passbook top plate 211, so that the passbook thick page 20 is lifted up and deformed. The passbook thick page 20 can minimize the adhesion between the page to be turned over and the page below it in the lifted free state, which greatly improves the success rate of page turning and reduces the probability of turning over double sheets.

[0081] like Figure 2 As shown, when the third-level friction wheel shaft 25 moves downward, the third-level friction wheel shaft 25 presses down a pair of passbook top plates 211 close to one end of the third-level friction wheel 231, thereby driving a pair of passbook top plates 211 to rotate around the top plate shaft 21 respectively, and finally forming Figure 5 When the passbook is in this position, the passbook thick page 20 is lifted up and deformed, and at the same time loses the clamping of the three-level friction wheel shaft 25 and the page turning passive wheel 112 on the page turning shaft 11, and becomes a free state. The passbook thick page 20 in such a lifted free state can minimize the adhesion between the page to be turned up and the page below it. Moreover, through experiments, this structure and setting method greatly improve the page turning success rate and reduce the probability of turning double pages. It is defined that when the passbook is in the open state, the passbook thick page 20 is formed with the passbook inner page with the turned-up page and the passbook inner page below it.

[0082] In order to realize the reset of the three-stage friction wheel shaft 25, a torsion spring is respectively sleeved on both ends of the three-stage friction wheel shaft 25 near the lower box side plate, and the torsion spring has two extended movable ends, and the two movable ends of the torsion spring are mounted on the top plate shaft 21. When the top folding cam 26 rotates to the initial position of the top folding cam 26, the top folding cam 26 does not contact the top folding moving shaft 27 at the initial position, and the page turning object is transmitted between the three-stage friction wheel shaft 25 and the page turning shaft 11, and the torsion spring drives the three-stage friction wheel shaft 25 to the initial position of the three-stage friction wheel shaft 25, and at the same time, a pair of passbook top plates 211 rotate around the top plate shaft 21 to the initial position under the action of gravity. In this embodiment, when the proximal end of the top folding cam 26 is closest to the top folding moving shaft 27, this position is the initial position of the top folding cam 26; the initial position of the tertiary friction wheel shaft 25 is the position where the friction wheel rubber ring 1112 on the friction wheel 231 is facing upward; the initial position of the tertiary friction wheel shaft 25 is the position when it is not driven 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 thereon can press down one end of the top plate 211 of the passbook, thereby driving the top plate 211 of the passbook to rotate around the top plate shaft 21, ensuring that the passbook can be effectively lifted and deformed during the page turning process, so that the adhesion between the page to be turned and the page below it is greatly reduced, making the page turning process smoother, thereby improving the success rate of page turning. Therefore, the probability of turning over two pages is greatly reduced, thereby significantly improving the operating efficiency. It is suitable for passbooks of different thicknesses and materials and has strong adaptability.

[0084] like Figure 1 , Figure 4 As shown, a group 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 one by one, and the channel detection sensors 6 located at the upper and lower sides are respectively located on both sides of the page turning wheel component 4. In some feasible embodiments, the channel detection sensor 6 adopts a through-beam photoelectric sensor to detect the starting point of the page turning of the passbook. When the page is turned forward, the passbook is transmitted to the Figure 4 In the position shown, at this time, the upper and lower channel detection sensors 6 close to one side of 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 provided near the entrance 9. The gate 7 is connected to the lower box body through a gate shaft provided along the length direction of the lower box body. A driving device is provided on one side of the gate 7. The gate 7 is driven by the driving device to rotate to open or close the entrance 9, thereby controlling the passbook to enter the passbook transmission channel. In some feasible embodiments, the driving device adopts an electric push rod, and an "L"-shaped frame is provided at the shaft 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 page does not need to be turned, the electric push rod pushes the "L"-shaped frame, thereby driving the gate shaft to rotate, the gate 7 is lifted up to close the entrance 9, and the passbook does not enter the passbook transmission channel. At this time, 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 can be imagined that the driving method of the gate 7 can be, but not limited to, driven by the electric push rod, and other methods that can realize the rotation of the gate 7 are all possible, and no limitation is made here.

[0086] A page-turning wheel sensor 8 is also provided at the compression fit corresponding to the page-turning wheel assembly 4. The page-turning wheel sensor 8 is provided on one side of the corresponding page-turning shaft 11 outside the lower box body. In this embodiment, the page-turning wheel sensor 8 adopts an infrared self-reflection sensor 15. A detection sheet is provided at the end of one side of the page-turning shaft 11. The detection sheet is located at the center of the end of the page-turning shaft 11, and the detection sheet also extends outwardly with a long end. The detection sheet 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, and this position can be set as the initial position of the page-turning wheel 111. At this position, the position where the friction wheel rubber ring 1112 is provided on 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, a self-reflection sensor 15 is respectively provided on one side of a pair of folding plates 132 close to the upper box body, that is, the self-reflection sensor 15 is fixed above the folding plates 132. In some feasible embodiments, the self-reflection sensor 15 is an infrared self-reflection sensor 15, which can be detected when the passbook enters the passbook transmission channel. When the inner page of the passbook lifts the folding plate 132, the self-reflection sensor 15 cannot detect the object. As the deformation of the inner page of the passbook increases, the self-reflection sensor 15 detects the object again. That is, when the passbook can be captured in the passbook transmission channel all the time, it proves that the inner page of the passbook has not been lifted by the passbook top plate 211. When the self-reflection sensor 15 detects something after failing to detect the object, it proves that the soft page has not been lifted. If the object is detected again after the object is not detected, it proves that the passbook has been turned over successfully. During the specific working process, when the page hooking piece 1113 hooks the tail end of the turned inner page and places it above the page turning wheel 111, the self-reflection sensor 15 on the folding plate 132 can detect the turned inner page of the passbook, so that it can be determined that the page turning is successful.

[0088] In the above scheme, the starting point of turning the page of the passbook 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 primary passive friction wheel 131 and the friction wheel 231 located on the primary friction wheel shaft 23 are pressed together to form a primary friction wheel assembly 3, the page turning wheel 111 and the page turning passive wheel 112 and the friction wheel 231 located on the tertiary friction wheel shaft 25 are pressed together to form a page turning wheel assembly 4, and the secondary passive friction wheel 141 and the friction wheel 231 located on the primary friction wheel shaft 23 are pressed together to form a secondary friction wheel assembly 5.

[0090] In the above scheme, the primary friction wheel assembly 3, the page turning wheel assembly 4 and the secondary friction wheel assembly 5 cooperate with each other to realize automatic page turning of the passbook and adjust it to the correct page, thereby improving efficiency, reducing error rate, reducing human intervention, and having wide applicability and greater market potential and application prospects.

[0091] The specific working process is as follows: the positions of all parts of the page turning device in the initial state are as follows: Figure 4 As shown, the passbook enters the boarding machine through the entrance 9 of the page turning device and stops at the channel detection sensor 6. Figure 4 The position shown in the figure, at this time, the front page 10 of the passbook extends through the opening on the upper box body; then Figure 2The top folding cam 26 starts to rotate 90 degrees, and the top folding moving shaft 27 starts to press down. The rotation of the top folding cam 26 can also drive the middle friction wheel shaft 22 to move downward. When the middle friction wheel shaft 22 moves downward, it drives the two passbook top plates 211 to rotate around the top plate shaft 21, and finally forms Figure 5 At this time, the passbook thick page 20 is lifted and deformed, and at the same time loses the clamping of the middle friction wheel 231 and the bearing on the page turning shaft 11, and becomes a free state.

[0092] Combined with the setting of the page turning wheel 111, when the tail end of the thick page 20 of the passbook is transmitted between the page turning shaft 11 and the secondary passive friction wheel shaft 14, the page turning shaft 11 then 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 over the inner page to be turned through friction. The turned inner page will push up the folding plate 132 during the upward warping process. When the page turning wheel 111 rotates to Figure 5 When the page is in the position shown, the turned inner page 30 is exactly at the position of the hook piece 1113 of the page turning wheel 111. As the page turning wheel 111 continues to rotate, the hook piece 1113 hooks the tail end of the turned inner page to the top of the page turning wheel 111. At this time, the self-reflection sensor 15 on the folding plate 132 can detect the turned inner page of the passbook, so that it can be determined that the page is turned successfully. After the page turning wheel 111 rotates one circle, it returns to the initial position. Figure 6 At this time, the top folding cam 26 rotates in the opposite direction to return to the initial position, and the passbook returns to the clamping state of the third-level friction wheel 231 and the page-turning passive wheel 112, and the top plate 211 of the passbook also returns to the initial position. Figure 6 The passbook moves forward to the entrance 9 driven by the primary friction wheel assembly 3 and the secondary friction wheel assembly 5, and the turned inner pages are flattened by the page turning passive wheel 112 on the page turning shaft 11 during the movement, completing the entire turning action.

[0093] If the passbook is judged to have been turned over two pages by the OCR (Optical Character Recognition) page recognition during supplementary boarding, the passbook will be returned to the page turning device from the entrance 9 again, and will stay at the position shown in the figure to complete the turning back of the wrongly turned page in the mirror image of the last page turning, that is, the reverse page turning. Figure 7 .

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
