Description

Technical Field

[0001] The present application relates to the technical field of page turning devices, and in particular to an automatic page turning device for certificates. Background Art

[0002] Currently, banks, hospitals, and real estate bureaus all use supplementary boarding to print related business documents. However, during the supplementary boarding process, if the current page of the certificate is fully printed, the certificate will be exited, and the staff or customer will need to manually turn the page and put it into the supplementary boarding.

[0003] If the staff or customers manually turn the pages of the certificate and put it into the supplementary boarding box, it will interrupt the business being conducted and reduce work efficiency. Utility Model Content

[0004] In order to improve the efficiency of certificate supplementary registration, the present application provides a device for automatically turning pages of certificates.

[0005] The automatic page turning device for certificates provided in this application adopts the following technical solution:

[0006] A device for automatically turning pages of a certificate comprises a mounting frame, and a transmission component and a page turning component simultaneously mounted on the mounting frame, the transmission component being capable of transmitting a certificate exiting a supplementary boarding machine to the page turning component, after the page turning component successfully turns pages of the certificate, the transmission component again transmits the certificate to the supplementary boarding machine, the page turning component comprising a page turning shaft rotatably connected to the mounting frame and a page turning wheel fixedly connected to the page turning shaft, a main wheel group for providing moving power for the certificate is provided below the page turning shaft, a guide plate fixedly connected to the mounting frame and capable of carrying the certificate is also provided below the page turning shaft, the page turning shaft passes through the center of the page turning wheel, a rubber column is fixedly connected to the page turning wheel, the main wheel group enables the certificate to move on the guide plate while the rubber column can turn pages of the certificate under the rotation of the page turning wheel, after the certificate page is successfully turned, the page turning shaft stops rotating.

[0007] By adopting the above technical solution, the automatic page turning device is installed at the back of the supplementary boarding machine. When the certificate of the supplementary boarding machine enters the installation frame from the rear exit, the transmission component will start immediately to transmit the certificate along the guide plate to the bottom of the page turning shaft. When the main wheel group drives the certificate to move forward on the guide plate, the rubber column will turn the pages of the certificate under the rotation of the page turning wheel. Once the certificate is turned successfully, the page turning shaft will stop rotating and the transmission component will start again to transmit the turned certificate back to the supplementary boarding machine, and the supplementary boarding machine will continue to make up for the certificate. During the whole process, no manual operation is required by staff or customers, which greatly improves work efficiency.

[0008] Optionally, the vertical cross-section of the page turning wheel is an equilateral triangle, and rubber columns are embedded on at most two corners of the page turning wheel, and the side walls of the rubber columns are flush with the side walls of the page turning wheel.

[0009] By adopting the above technical solution, the corners of the page turning wheel inlaid with rubber columns can turn the pages of the certificate, and the other corners of the page turning wheel not inlaid with rubber columns can guide the certificate.

[0010] Optionally, the transmission assembly includes an engaging wheel group, which includes an upper wheel group and a lower wheel group engaged with the upper wheel group, and the upper wheel group and the lower wheel group are both rotatably connected to the mounting frame. The certificate can be squeezed into the channel between the upper wheel group and the lower wheel group and reach under the page turning shaft through the cooperation of the upper wheel group and the lower wheel group.

[0011] By adopting the above technical solution, the upper wheel group and the lower wheel group are meshed, and the certificate can be squeezed into the channel between the upper wheel group and the lower wheel group. The upper wheel group and the lower wheel group jointly provide power for the transportation of the certificate, and at the same time can flatten the warped certificate pages on the certificate, thereby improving the stability of the certificate page turning process.

[0012] Optionally, the transmission assembly also includes a booster wheel group that can further assist the certificate in moving below the page turning shaft. The booster wheel group is connected to the mounting frame and is arranged between the meshing wheel group and the main wheel group. The guide plate is arranged above the main wheel group and extends to below the booster wheel group and further extends to below the upper wheel group.

[0013] By adopting the above technical solution, the power-assist wheel group can provide additional assistance during the certificate transmission process, ensuring that the certificate can reach the bottom of the page-turning axis more smoothly. It can also flatten certificates with pages warped upward to avoid jamming and folding. Tests have found that the presence of the power-assist wheel can greatly reduce the probability of the page-turning wheel turning over multiple pages.

[0014] Optionally, the conveying assembly is configured as two groups, which are symmetrically distributed on both sides of the page turning axis. At the same time, the guide plate extends to the bottom of the power-assisting wheel group on the other side, and further extends to the bottom of the upper wheel group on the other side, so that the certificate can be turned in two different directions along the guide plate.

[0015] By adopting the above technical solution and designing two sets of transmission components, which are symmetrically distributed on both sides of the page turning axis, the requirement of bidirectional page turning of certificates can be met, thus meeting the requirements of a wider range of application scenarios.

[0016] Optionally, the main wheel group, upper wheel group, lower wheel group and power-assisted wheel group all include a rotating shaft and a rotating wheel connected to the rotating shaft, the rotating wheels are all covered with elastic rubber rings, and a plurality of through holes are provided on the guide plate, and the rotating wheel under the guide plate can directly assist the certificate through the through holes.

[0017] Optionally, the wheels in the two lower wheel groups and the main wheel group are fixedly connected to the corresponding rotating shafts, and their rotating shafts rotate simultaneously and in the same direction. The connection between the wheel in the power-assisted wheel group and the rotating shaft is a rotating connection. The wheel in the power-assisted wheel rotates passively, and the page-turning wheel has the same rotation direction as the wheel in the main wheel group.

[0018] By adopting the above technical solution, when the certificate is transmitted from the supplementary boarding plane, two sets of meshing wheel groups and one set of main wheel groups are turned on at the same time, and the power-assisting wheel group rotates passively to transmit the certificate to the end of the installation frame away from the supplementary boarding plane, and then the rotation direction of the meshing wheel group and the main wheel group is adjusted to make the certificate move in the direction of the supplementary boarding plane. When the certificate moves below the page turning shaft, the page turning shaft rotates. After the rubber column successfully turns the page, the page turning shaft stops rotating, and the main wheel group, the power-assisting wheel group and the meshing wheel group continue to transmit the certificate to the supplementary boarding plane.

[0019] Optionally, both ends of the page-turning shaft are also rotatably connected to fixed frames, and the end of the fixed frame away from the page-turning shaft is socketed with the rotating shaft of one of the upper wheel groups. The mounting frame is provided with a movable groove that can accommodate the up and down movement of the page-turning shaft. The fixed frame can rotate around the rotating shaft on the upper wheel group, and the page-turning wheel relies on the weight of the fixed frame, the rotating shaft, and the page-turning wheel to provide friction for turning pages, so that the rubber column can only turn over one page of the certificate.

[0020] Optionally, the motor is mounted on the mounting frame, the output shaft of the motor is fixedly connected to the first gear, the end of the rotating shaft mounted on the fixed frame is fixedly connected to the second gear, the first gear and the second gear are connected by a conveyor belt, the end of the page turning shaft close to the second gear is fixedly connected to the third gear, the third gear and the second gear are connected by a conveyor belt, the page turning shaft moves up and down in the movable groove with the second gear as the center and the conveyor belt between the third gear and the second gear as the radius, and the movable groove is arranged in an arc shape.

[0021] By adopting the above technical solution, the page turning wheel needs to apply a certain pressure on the surface of the certificate during the page turning process, so as to form a friction force sufficient to turn the page. However, in the actual process, if the pressure is too large, it is easy to turn over multiple pages, and if the pressure is too small, it is not enough to turn over the page, so the accuracy of the pressure setting is required to be high. At this time, if an adaptive device such as a compression spring is used, the pressure of the compression spring will inevitably change over time, causing a change in friction. Therefore, in this application, the page turning shaft is fixed on the page turning fixed frame, and the other end of the page turning fixed frame is sleeved on the upper wheel group shaft and can rotate around the shaft. The other end provides friction for turning the page by relying on the weight of the fixed frame, the shaft, and the page turning wheel, thereby ensuring that the friction does not change due to changes in time, and after a jam occurs, the fixed frame can be lifted to expose the channel, so that the jammed certificate can be easily removed.

[0022] Optionally, a main sensor and a sub-sensor are connected to the mounting frame, and when the main sensor and the sub-sensor are blocked by the certificate at the same time, the certificate page is turned successfully.

[0023] By adopting the above technical solution, through precise sensing and control of the main and auxiliary sensors, the control system can ensure the accuracy and stability of the certificate during the automatic page turning process.

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

[0025] 1. Install the automatic page turning device behind the supplementary boarding machine. When the certificate for supplementary boarding enters the installation frame from the rear exit, the transmission component will start immediately and transmit the certificate along the guide plate to the bottom of the page turning shaft. When the main wheel group drives the certificate to move forward on the guide plate, the rubber column will turn the page of the certificate under the rotation of the page turning wheel. Once the certificate page is turned successfully, the page turning shaft will stop rotating and the transmission component will start again to transmit the turned page certificate back to the supplementary boarding machine, and the supplementary boarding machine will continue to make up for the certificate. During the whole process, no manual operation is required by the staff or customers, which greatly improves the work efficiency;

[0026] 2. The vertical section of the page turning wheel is an equilateral triangle. The corners of the page turning wheel inlaid with rubber columns can turn the pages of the certificate, and the other corners of the page turning wheel not inlaid with rubber columns can guide the certificate.

[0027] 3. In the present application, the page turning shaft is fixed on the page turning fixing frame, and the other end of the page turning fixing frame is sleeved on the rotating shaft of the upper wheel group and can rotate around the rotating shaft. The other end provides friction for turning pages by relying on the weight of the fixing frame, the rotating shaft and the page turning wheel, thereby ensuring that the friction does not change with the change of time, and after a jam occurs, the fixing frame can be lifted to expose the channel, so as to facilitate the removal of the jammed certificate.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The embodiment of the present application discloses a device for automatically turning pages of certificates.

[0037] like Figure 1 and Figure 2 As shown, a certificate automatic page turning device includes a mounting frame 1 and a transmission component 2 and a page turning component 3 installed on the mounting frame 1 at the same time. The transmission component 2 is responsible for transmitting the certificate for supplementary boarding to the page turning component 3, and the page turning component 3 is responsible for turning the pages of the certificate. Once the certificate page is turned successfully, the transmission component 2 will transmit the certificate back to the supplementary boarding again, thereby completing the entire automatic page turning process.

[0038] like Figure 1 and Figure 2 As shown, specifically, the page turning assembly 3 is the core part of the device, which includes a page turning shaft 31 rotatably connected to the mounting frame 1 and a page turning wheel 32 fixedly connected to the page turning shaft 31. A main wheel group 4 is also provided below the page turning shaft 31 to provide moving power for the certificate. A guide plate 11 is also provided below the page turning shaft 31 to be fixedly connected to the mounting frame 1. The guide plate 11 can carry the certificate and ensure the stability of the certificate during the page turning process. Figure 1 and Figure 3 As shown, the page turning shaft 31 passes through the center of the page turning wheel 32, and a rubber column 321 is fixedly connected to the page turning wheel 32. When the main wheel group 4 drives the certificate to move on the guide plate 11, the rubber column 321 will turn the pages of the certificate under the rotation of the page turning wheel 32. Once the certificate page is turned successfully, the page turning shaft 31 will stop rotating, and the transmission component 2 will transmit the certificate back to the boarding.

[0039] The automatic page turning device is installed at the back of the supplementary boarding machine. When the certificate of the supplementary boarding machine enters the installation frame 1 from the rear exit, the transmission component 2 will start immediately and transmit the certificate along the guide plate 11 to the bottom of the page turning shaft 31. When the main wheel group 4 drives the certificate to move forward on the guide plate 11, the rubber column 321 will turn the pages of the certificate under the rotation of the page turning wheel 32. The turned certificate page rests on the page turning wheel 32, the page turning shaft 31 will stop rotating, and the transmission component 2 will transmit the turned certificate back to the supplementary boarding machine, and the supplementary boarding machine will continue to make up for the certificate. During the whole process, no manual operation is required by the staff or customers, which greatly improves the work efficiency.

[0040] like Figure 2 As shown, the vertical section of the page turning wheel 32 is an equilateral triangle, and rubber columns 321 are embedded on at most two corners of the page turning wheel 32. The side walls of the rubber columns 321 are flush with the side walls of the page turning wheel 32, so that the rubber columns 321 do not protrude from the equilateral triangle.

[0041] This design allows the corners of the page turning wheel 32 inlaid with the rubber column 321 to turn the pages of the certificate, and the other corners of the page turning wheel 32 not inlaid with the rubber column 321 can guide the certificate.

[0042] like Figure 1 and Figure 2 As shown, the transmission assembly 2 includes a meshing wheel set 21, which is composed of an upper wheel set 211 and a lower wheel set 212 meshed up and down. The upper wheel set 211 and the lower wheel set 212 are both rotatably connected to the mounting frame 1, and the certificate can be smoothly squeezed into the channel between the upper wheel set 211 and the lower wheel set 212, and the certificate is transmitted to the bottom of the page turning shaft 31 through their cooperation; the transmission assembly 2 also includes a booster wheel set 22 that can further assist the certificate to move below the page turning shaft 31, the booster wheel set 22 is connected to the mounting frame 1, and is arranged between the meshing wheel set 21 and the main wheel set 4, and the guide plate 11 is arranged above the main wheel set 4, and extends parallel to the bottom of the booster wheel set 22, and further extends to the bottom of the upper wheel set 211.

[0043] The upper wheel group 211 and the lower wheel group 212 jointly provide power for the transportation of the certificate, and can also flatten the warped certificate pages on the certificate, thereby improving the stability of the certificate page turning process. The power-assisted wheel group 22 can provide additional assistance during the certificate transmission process, ensuring that the certificate can reach the bottom of the page turning shaft 31 more smoothly, and can also further flatten the certificates with pages warped upward to avoid jamming and folding. It has been found through testing that the presence of the power-assisted wheel can greatly reduce the probability of the page turning wheel 32 turning over multiple pages.

[0044] like Figure 1 and Figure 2As shown, the transmission component 2 is configured as two groups, which are symmetrically distributed on both sides of the page turning shaft 31. At the same time, the guide plate 11 extends parallel to the bottom of the power-assisting wheel group 22 on the other side, and further extends to the bottom of the upper wheel group 211 on the other side, so that the certificate can be turned in two different directions along the guide plate 11 to meet the needs of a wider range of application scenarios.

[0045] like Figure 1 and Figure 2 As shown, the main wheel group 4, the upper wheel group 211, the lower wheel group 212 and the auxiliary wheel group 22 all include a rotating shaft 5 and a rotating wheel 51 connected to the rotating shaft 5, and the rotating wheel 51 is sleeved with an elastic rubber ring 511. A plurality of through holes 111 are provided on the guide plate 11, and the rotating wheel 51 under the guide plate 11 can directly contact the certificate through the through holes 111.

[0046] like Figure 1 and Figure 2 As shown, the two lower wheel groups 212 and the rotating wheel 51 in the main wheel group 4 are fixedly connected to the corresponding rotating shaft 5, as shown in FIG. Figure 2 and Figure 4 As shown, the two lower wheel groups 212 and the main wheel group 4 rotate synchronously with the same motor through three groups of conveyor belt assemblies. Specifically, one of the lower wheel groups 212 rotates synchronously with the motor through the conveyor belt assembly, and this lower wheel group 212 also rotates synchronously with the main wheel group 4 through the conveyor belt assembly. The main wheel group 4 rotates synchronously with the other lower wheel group 212 through the conveyor belt assembly. Therefore, the two lower wheel groups 212 and the wheels 51 in the main wheel group 4 rotate simultaneously and in the same direction. The connection between the power-assisted wheel group 22 and the wheels 51 in the two upper wheel groups 211 and the rotating shaft 5 is a rotating connection. Therefore, the two upper wheel groups 211 and the wheels 51 in the power-assisted wheel all rotate passively, and the page-turning wheel 32 has the same rotation direction as the wheel 51 in the main wheel group 4 to achieve the purpose of turning pages.

[0047] When the certificate is transmitted from the supplementary boarding, two sets of meshing wheel groups 21 and one set of main wheel group 4 are turned on at the same time, and the auxiliary wheel group 22 rotates passively to transmit the certificate to the end of the installation frame 1 away from the supplementary boarding, and then the rotation direction of the meshing wheel group 21 and the main wheel group 4 is adjusted to make the certificate move in the opposite direction of the supplementary boarding. When the certificate moves below the page turning shaft 31, the page turning shaft 31 rotates. After the rubber column 321 successfully turns the page, the page turning shaft 31 stops rotating, and the main wheel group 4, the auxiliary wheel group 22 and the meshing wheel group 21 continue to transmit the certificate to the supplementary boarding.

[0048] like Figure 4 and Figure 5As shown, both ends of the page turning shaft 31 are also rotatably connected to the fixing frame 6, and the end of the fixing frame 6 away from the page turning shaft 31 is sleeved with the rotating shaft 5 of one of the upper wheel groups 211. A pair of movable grooves 12 that can accommodate the up and down movement of the page turning shaft 31 are provided on the mounting frame 1. The fixing frame 6 can rotate around the rotating shaft 5 of the upper wheel group 211, and the page turning wheel 32 relies on the weight of the fixing frame 6, the rotating shaft 5, and the page turning wheel 32 itself to provide friction for turning pages, so that the rubber column 321 can only turn over one page of the certificate.

[0049] like Figure 4 and Figure 6 As shown, a first gear 13 is provided on the outside of the side wall of the mounting frame 1, and the motor is installed inside the mounting frame. The first gear 13 is fixedly connected to the output shaft of the motor, and the end of the rotating shaft 5 which is sleeved with the fixing frame 6 is fixedly connected to the second gear 14. The first gear 13 and the second gear 14 realize synchronous rotation through a conveyor belt. The end of the page turning shaft 31 close to the second gear 14 is fixedly connected to the third gear 15, and the third gear 15 and the second gear 14 are connected through a conveyor belt. The first gear 13, the second gear 14 and the third gear 15 are all arranged on the outside of the outer wall of the mounting frame 1, and the page turning shaft 31 moves up and down in the movable groove 12 with the second gear 14 as the center and the conveyor belt between the third gear 15 and the second gear 14 as the radius, and the movable groove 12 is arranged in an arc shape.

[0050] The page turning wheel 32 needs to apply a certain pressure on the surface of the certificate during the page turning process, so as to form a friction force sufficient to turn the page. However, in the actual process, if the pressure is too large, it is easy to turn over multiple pages, and if the pressure is too small, it is not enough to turn over the page, so the accuracy of the pressure setting is required to be high. At this time, if an adaptive device such as a compression spring is used, the pressure of the compression spring will inevitably change over time, causing a change in friction. Therefore, in this application, the page turning shaft 31 is fixed on the page turning fixed frame 6, and the other end of the page turning fixed frame 6 is sleeved on the upper wheel group 211 shaft 5, which can rotate around the shaft 5. The other end provides friction for turning the page by relying on the weight of the fixed frame 6, the shaft 5, and the page turning wheel 32, thereby ensuring that the friction does not change due to changes in time, and after a jam occurs, the fixed frame 6 can be lifted to expose the channel, so that the jammed certificate can be easily removed.

[0051] The fixing frame 6 is connected with a main sensor 7, and the guide plate 11 is connected with a sub-sensor 8. When the page is turned successfully, the turned page can block the main sensor 7. At the same time, the certificate blocks the sub-sensor 8. Therefore, when the main sensor 7 and the sub-sensor 8 are blocked by the certificate at the same time, the certificate is turned successfully. The main sensor 7 and the sub-sensor 8 improve the accuracy and stability of the certificate during the automatic page turning process.

[0052] The implementation principle of an automatic page turning device for a certificate in an embodiment of the present application is as follows: when the certificate is transmitted after supplementary boarding, two sets of meshing wheel groups 21 and one set of main wheel group 4 are turned on at the same time, and the power-assisting wheel group 22 rotates passively to transmit the certificate to the end of the installation frame 1 away from the supplementary boarding, and then the rotation direction of the meshing wheel group 21 and the main wheel group 4 is adjusted to make the certificate move in the opposite direction of the supplementary boarding. When the certificate moves below the page turning shaft 31, the page turning shaft 31 rotates. After the rubber column 321 successfully turns the page, the page turning shaft 31 stops rotating, and the main wheel group 4, the power-assisting wheel group 22 and the meshing wheel group 21 continue to transmit the certificate to the supplementary boarding.

[0053] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
