Description

Technical Field

[0001] This application relates to the technical field of self-service equipment and self-service terminals in the financial sector, and in particular to a folding device for turning pages of a passbook. Background Technology

[0002] Currently, medical, pension, and subsidy payments are disbursed through passbook accounts. Passbooks also allow real-time monitoring of deposit and withdrawal amounts, and many elderly people are accustomed to using passbooks for deposits and withdrawals, resulting in a high utilization rate of passbooks. Some passbook refill machines are equipped with passbook page-turning mechanisms, which can be placed in bank lobbies for customers to operate independently. When the current passbook is full or the customer inserts a non-printable page, the device can automatically turn the page to the correct one.

[0003] Currently, some passbook page-turning mechanisms exist, but the curling of the inner pages during the page-turning process takes up space. There are two main approaches: one is to use a fixed pressure plate in the upper channel, but at a certain distance from the page-turning rollers, allowing space for the curled pages to be turned. However, this can cause the passbook to slip through the gap between the pressure plate and the page-turning rollers if the passbook deforms significantly, resulting in jamming. Another approach is to make the page-turning plate rotatable, such as the design in patent application CN118230469A, entitled "A Passbook Inner Page Forward and Reverse Page-Turning Device." When the inner pages are turned, their curling motion pushes up the pressure plate. The advantage of this is that the pressure plate can fill the channel and prevent jamming. The disadvantage is that the weight of the pressure plate acts on the curled pages during page-turning, which may cause page-turning failure. Summary of the Invention

[0004] To improve the success rate of turning pages in a passbook, this application provides a folding device for turning pages in a passbook.

[0005] The folding device for turning pages in a passbook provided in this application adopts the following technical solution:

[0006] A pressure-folding device for turning pages of a passbook is disposed in the upper component of the passbook turning mechanism. The upper component is used to form a transmission channel for the passbook between itself and the lower component. The upper component includes a page-turning shaft and pressure-folding plates symmetrically disposed on both sides of the page-turning shaft. Page-turning wheels are sleeved on the page-turning shaft.

[0007] The folding device for turning pages in a passbook includes a follower structure corresponding to the folding plate, which actively flips the folding plate as the inner pages of the passbook are rolled up. Each follower structure includes a transmission component and a actuating component. The folding plate rests on the actuating component. The transmission component is used to cooperate with the page-turning shaft to drive the actuating component to rotate synchronously. The two actuating components are symmetrically arranged. The folding plate near the passbook entrance is configured to be raised at a certain angle when the page-turning shaft rotates in a first direction. The folding plate away from the passbook entrance is configured to be raised at a certain angle when the page-turning shaft rotates in a second direction. The first direction and the second direction are two opposite directions.

[0008] By adopting the above technical solution and adding a folding device for turning the passbook pages, a connection can be established between the folding plate and the page-turning shaft. During the page-turning process, the folding plate can automatically adjust its lifting angle according to the rotation angle of the page-turning shaft and the page-turning wheel. That is, the folding plate is actively lifted during the page-turning process rather than being passively pushed up by the curled page, thereby avoiding space for page curling. Furthermore, the presence of two folding plates before page turning can ensure the integrity of the passbook transmission channel, flattening any upwardly deformed or warped passbook pages so that they can pass normally through each set of friction wheels, reducing the probability of the passbook getting stuck in the transmission channel.

[0009] Preferably, the actuating element includes a support shaft extending axially along the page-turning axis, and the pressure plate rests on the support shaft. In the initial state, the support shaft is positioned below the horizontal center line of the page-turning wheel so that the pressure plate is arranged horizontally. As the page-turning axis rotates, the support shaft moves from below the horizontal center line of the page-turning wheel to above the horizontal center line of the page-turning wheel.

[0010] By adopting the above technical solution, a support shaft that can be displaced with the rotation of the page-turning shaft is set up. The pressure plate is placed on the support shaft. In the initial state, the support shaft is set below the center horizontal line of the page-turning wheel to ensure that the pressure plate coincides with the center horizontal line of the page-turning wheel. As the page-turning shaft rotates to turn the pages of the passbook, the support shaft gradually moves from below the center horizontal line of the page-turning wheel to above the center horizontal line, so as to turn the pressure plate upward at a certain angle, so that the pressure plate avoids the curled pages. The pressure plate either does not contact the pages of the passbook, or applies gravity to the support shaft to prevent the pages of the passbook from failing to turn due to the gravity of the pressure plate.

[0011] Preferably, the actuating component further includes a pressure roller, which rotates synchronously with the transmission component. The support shaft is eccentrically disposed on the end face of the pressure roller, and the support shaft gradually moves from the end away from the friction wheel to the friction wheel as the pressure roller rotates.

[0012] By adopting the above technical solution, when the page-turning shaft rotates, the pressure plate and the page-turning shaft rotate synchronously with the help of the transmission component. Since the support shaft is eccentrically set on the end face of the pressure plate and below the center horizontal line of the page-turning wheel, as the pressure plate rotates clockwise or counterclockwise, the support shaft gradually moves from the end of the pressure plate away from the friction wheel to the end of the pressure plate closer to the friction wheel, and rotates from below the center horizontal line of the page-turning wheel to above the center horizontal line, so as to smoothly flip the pressure plate upward at a certain angle and avoid the curled pages.

[0013] Preferably, the pressing wheel is a pressing ratchet, and a pressing pawl for engaging with the pressing ratchet is rotatably disposed above the pressing ratchet, and the two pressing ratchets are symmetrically arranged.

[0014] By adopting the above technical solution, it was found in actual use that factors such as its own weight, vibration, and accidental touch by personnel can cause the originally stationary pressure wheel to deviate from its initial position. By designing the pressure wheel as a pressure ratchet and designing a pressure pawl that can lock in one direction with it, the pressure wheel can be prevented from deviating from its initial position under external force.

[0015] Preferably, the transmission component includes a driving gear, a first driven gear, and a second driven gear. The driving gear is arranged at the end of the page-turning shaft, and the first driven gear and the second driven gear are arranged on both sides of the driving gear and mesh with the driving gear.

[0016] The first driven gear, the second driven gear, and the actuating member all rotate coaxially via a transmission shaft. The actuating member is mounted on the transmission shaft by a limiting member. The limiting member and the actuating member are configured to rotate synchronously when the transmission shaft rotates in a first direction and to rotate relative to each other when the transmission shaft rotates in a second direction.

[0017] By adopting the above technical solution, when the page-turning shaft rotates, it drives the drive gear to rotate synchronously. The rotation of the drive gear, in turn, drives the first driven gear and the second driven gear on both sides to rotate, one clockwise and the other counterclockwise. The two actuating parts are subject to the action of the limiting parts. By reasonably setting the limiting parts, when the page-turning shaft rotates in the first direction (clockwise / counterclockwise) to turn the inner page, the actuating part near the passbook entrance is locked to the transmission shaft by the limiting parts, so that the actuating part rotates synchronously with the transmission shaft, thereby making the pressure... The folding plate is flipped upwards at a certain angle by the rotation of the actuating component, actively avoiding the space where the inner pages of the passbook curl. The actuating component and the drive shaft on the side away from the passbook entrance are not locked, and the drive shaft rotates freely within the actuating component, so that the folding plate on the side away from the passbook entrance remains in its initial state (horizontal state). Similarly, when the inner pages of the passbook are flipped up, the page-turning shaft rotates in the opposite direction, that is, it rotates in the second direction, so that the actuating component and the drive shaft on the side away from the passbook entrance are locked. The actuating component rotates with the drive shaft to flip the folding plate on the side away from the passbook entrance upwards at a certain angle.

[0018] Preferably, the limiting component is a one-way bearing, which is mounted on the drive shaft on the side near the passbook entrance in a first end direction, and on the drive shaft on the side away from the passbook entrance in a second end direction.

[0019] By adopting the above technical solution, using a single-row bearing and reasonably setting the installation direction of the one-way bearing, it is easy for the two pressure plates to achieve different actions when the page-turning shaft rotates in different directions, making the follow-up structure simpler and the installation more convenient.

[0020] Preferably, the number of teeth of the first driven gear and the second driven gear is greater than the number of teeth of the driving gear.

[0021] By adopting the above technical solution, there is a transmission ratio between the driving gear and the first driven gear and the second driven gear. When the page turning shaft and the driving gear rotate one revolution, the rotation angle of the first driven gear and the second driven gear is less than one revolution, so that the actuating part also rotates less than one revolution, so as to smoothly lift the pressure plate to a certain angle.

[0022] Preferably, the gear ratio of the first driven gear, the second driven gear and the driving gear is 2:1, and the page-turning shaft is configured to rotate counterclockwise two times and then clockwise two times.

[0023] By adopting the above technical solution, after the page-turning wheel successfully turns one page in one revolution, the ratchet on the right side only rotates half a revolution due to the gear ratio, and the pressure plate jumps to the highest position, completely clearing the curled page. After the channel engagement wheel drives the passbook out of the channel, the page-turning wheel rotates counterclockwise one revolution again, so that the ratchet and pressure plate on the right side return to their initial positions.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The folding device for turning pages of a passbook in this application can establish a connection between the page turning shaft and the folding plate. When the page turning shaft rotates, the transmission component rotates with the page turning shaft and transmits the information to the actuating component. The actuating component drives the folding plate to lift up at a certain angle, so that the folding plate actively avoids the curled pages during the page turning process, reducing the probability of page turning failure.

[0026] 2. A transmission component is installed between the drive shaft and the page-turning shaft to achieve gear transmission. When the page-turning shaft rotates, the rotation directions of the two drive shafts are opposite. One-way bearings are used to install the actuating component on the drive shaft, and the directions of the two one-way bearings are reasonably arranged. When the page-turning shaft rotates in the first or second direction, one actuating component rotates while the other actuating component does not rotate, so that one pressing plate is raised at a certain angle while the other pressing plate remains stationary, so as to fill the channel and avoid jamming.

[0027] 3. By setting the gear ratio of the first driven gear, the second driven gear and the driving gear to 2:1, when the page-turning shaft rotates one revolution to turn the inner page of the passbook, the support shaft rotates from below the central axis of the page-turning wheel to above the central axis of the page-turning wheel, and moves from the end of the pressure plate away from the friction wheel to the end of the pressure plate close to the friction wheel, so that the pressure plate is raised at a certain angle to avoid the space for page curling, avoid the pressure plate affecting the folding of the inner page, and improve the success rate of folding.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses a folding device for turning pages in a passbook. An upper component 01 is disposed in the passbook turning mechanism, forming a transmission channel for the passbook between the upper component 01 and the lower component 02. The upper component 01 includes a rotatably mounted page-turning shaft 011 and folding plates 012 symmetrically arranged on both sides of the page-turning shaft 011. The heads of the folding plates 012 on both sides are arranged opposite to each other. A page-turning wheel 013 is fixedly sleeved on the page-turning shaft 011. (Refer to...) Figures 1-3 The folding device for turning pages in a passbook includes a follower structure 1 provided corresponding to the folding plate 012 for actively turning the folding plate 012 upward during the process of the inner pages of the passbook curling. The follower structure 1 is used to make the folding plate 012 avoid the space of the inner pages of the passbook curling, so as to avoid the failure of turning pages due to the gravity of the folding plate 012 being applied to the curled pages.

[0034] Reference Figures 1-3 Each follower structure 1 includes a transmission component 11 and an actuating component 12. A pressure plate 012 rests on the actuating component 12. The transmission component 11 cooperates with the page-turning shaft 011 to drive the actuating component 12 to rotate synchronously. The two actuating components 12 are symmetrically arranged. The pressure plate 012 near the passbook entrance is configured to lift upwards at a certain angle when the page-turning shaft 011 rotates in a first direction, while the pressure plate 012 away from the passbook entrance remains stationary when the page-turning shaft 011 rotates in the first direction. The pressure plate 012 away from the passbook entrance is configured to lift upwards at a certain angle when the page-turning shaft 011 rotates in a second direction, while the pressure plate 012 near the passbook entrance remains stationary when the page-turning shaft 011 rotates in the second direction. The first direction and the second direction are opposite directions.

[0035] Reference Figure 1 Specifically, the transmission component 11 includes a driving gear 111, a first driven gear 112, and a second driven gear 113. The driving gear 111 is located at the end of the page-turning shaft 011, and the first driven gear 112 and the second driven gear 113 are located on both sides of the driving gear 111 and both mesh with the driving gear 111. The first driven gear 112, the second driven gear, and the actuating component 12 all rotate coaxially via the transmission shaft 114.

[0036] Reference Figure 2 and Figure 3Specifically, the actuating element 12 includes a pressing and folding wheel 121 sleeved on the drive shaft 114 and a support shaft 122 disposed on the end face of the pressing and folding wheel 121 and extending axially along the page-turning shaft 011. The pressing and folding plate 012 rests on the support shaft 122. The support shaft 122 is eccentrically disposed on the end face of the pressing and folding wheel 121. In the initial state, the support shaft 122 is positioned below the center horizontal line of the page-turning wheel 013, so that the pressing and folding plate 012 is arranged horizontally and coincides with the center horizontal line of the page-turning wheel 013. As the page-turning shaft 011 rotates, the support shaft 122 moves from below the center horizontal line of the page-turning wheel 013 to above the center horizontal line of the page-turning wheel 013. The pressure plate 012 is flipped upward at a certain angle so that it avoids the curled pages. The pressure plate 012 either does not contact the inner pages of the passbook, or the gravity is applied to the support shaft 122 to prevent the inner pages of the passbook from failing to turn due to the gravity of the pressure plate 012.

[0037] Preferably, in the initial state, the support shaft 122 is located at the end of the pressure plate 012 away from the friction wheel. As the pressure wheel 121 rotates, the support shaft 122 gradually moves from the end of the pressure plate 012 away from the friction wheel to the end of the pressure plate 012 close to the friction wheel, so as to smoothly flip the pressure plate 012 upward.

[0038] When the drive gear 111 rotates, the first driven gear 112 and the second driven gear 113 rotate in opposite directions. To fill in the gaps in the passage during the folding of the inner pages of the passbook and prevent jamming, the actuating member 12 is mounted on the drive shaft 114 via a limiting member (not shown in the figure). Furthermore, the limiting member and the actuating member 12 are configured to rotate synchronously when the drive shaft 114 rotates in the first direction and to rotate relative to each other when the drive shaft 114 rotates in the second direction. When the page-turning shaft 011 rotates in the first direction (clockwise / counterclockwise) to flip the inner pages, the actuating member 12 near the passbook entrance is locked to the transmission shaft 114 by a limiting member, so that the actuating member 12 rotates synchronously with the transmission shaft 114. This causes the pressure plate 012 to be flipped upwards at a certain angle by the rotation of the actuating member 12, actively avoiding space for the inner pages of the passbook to curl. The actuating member 12 away from the passbook entrance and the transmission shaft 114 are unlocked, and the transmission shaft 114 rotates freely within the actuating member 12, so that the pressure plate 012 away from the passbook entrance remains in its initial state (horizontal state). Similarly, when the inner pages of the passbook are flipped, the page-turning shaft 011 rotates in the opposite direction, that is, in the second direction, so that the actuating member 12 away from the passbook entrance and the transmission shaft 114 are locked. The actuating member 12 rotates with the transmission shaft 114 to flip the pressure plate 012 away from the passbook entrance upwards at a certain angle.

[0039] In this application, the limiting component is a one-way bearing. The one-way bearing is mounted on the drive shaft 114 near the passbook inlet in a first end direction, and on the drive shaft 114 away from the passbook inlet in a second end direction. By appropriately setting the mounting direction of the one-way bearing, it is possible for the two pressure plates 012 to perform different actions when the page-turning shaft 011 rotates in different directions.

[0040] Since the page-turning shaft 011 and page-turning wheel 013 need to rotate one revolution to turn the inner pages of the passbook, in order to ensure that after the page-turning wheel 013 rotates one revolution, the pressure wheel 121 also rotates one revolution with the page-turning shaft 011 to rotate the support shaft 122 to the initial position, thus preventing the pressure plate 012 from being lifted smoothly, it is necessary to set the number of teeth of the first driven gear 112 and the second driven gear 113 to be greater than the number of teeth of the driving gear 111.

[0041] Preferably, the gear ratio of the first driven gear 112, the second driven gear 113, and the driving gear 111 is 2:1, and the page-turning shaft 011 is configured to rotate counterclockwise two revolutions and then clockwise two revolutions. That is, after the page-turning shaft 011 rotates one revolution to turn the inner page of the passbook, the pressure roller 121 and the support shaft 122 only rotate half a revolution, so that the support shaft 122 moves from the end of the pressure plate 012 away from the friction wheel and below the center horizontal line of the page-turning wheel 013 to the end of the pressure plate 012 near the friction wheel and above the center horizontal line of the page-turning wheel 013. At this time, the pressure plate 012 is raised to its highest position, maximizing the avoidance of the curled page and greatly improving the success rate of page turning. After the page is successfully turned, the page-turning shaft 011 continues to rotate one revolution, so that the pressure plate 012 returns to its initial position.

[0042] Reference Figure 2 and Figure 3 Because it was found in actual use that factors such as gravity, vibration, and accidental touch by personnel can cause the originally stationary folding wheel 121 to deviate from its initial position, in order to prevent the folding wheel 121 from deviating from its initial position under external forces and affecting page folding, this application designs the folding wheel 121 as a folding ratchet. A folding pawl 123 is rotatably provided above the folding ratchet for engaging with it. The two folding ratchets are symmetrically arranged. This ensures that the folding ratchets on both sides can only rotate in the standard direction of operation, preventing the folding wheel 121 from deviating from its initial position under external forces.

[0043] The implementation principle of a folding device for turning pages in a passbook according to an embodiment of this application is as follows: During the page turning process, the page turning shaft 011 first rotates in the first direction (taking the counterclockwise direction as an example), driving the page turning wheel 013 and the drive gear 111 to rotate. The rotation of the drive gear 111 drives the first driven gear 112 and the second driven gear 113 on both sides to rotate in opposite directions. Due to the action of the one-way bearing, the actuating member 12 on the side closer to the passbook entrance rotates synchronously with the transmission shaft 114, while the actuating member 12 on the side farther from the passbook entrance rotates relative to the transmission shaft 114. When the page turning shaft 011 rotates one revolution, the folding plate 012 and the support shaft 122 rotate half a revolution, causing the support shaft 122 to move from the end of the folding plate 012 away from the friction wheel and below the center horizontal line of the page turning wheel 013 to the end of the folding plate 012 closer to the friction wheel and above the center horizontal line of the page turning wheel 013. At this time, the folding plate 012 is raised to its highest point, avoiding the curled page, and the page is successfully turned up. Then, the page-turning axis 011 continues to rotate counterclockwise one full turn, causing the support axis 122 to rotate half a full turn and return to its initial position, and the pressure plate 012 also returns to its initial position. Then, the page-turning wheel 013 rotates clockwise one full turn, and the pressure plate 121 and support axis 122 on the side away from the passbook entrance rotate half a full turn to lift the pressure plate 012 to its highest position, avoiding the curled pages, so that the passbook pages can be turned up smoothly.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
