Description

Technical Field

[0001] The utility model is used in the field of page turning equipment, in particular to a page turning device and self-service equipment. Background Art

[0002] With the advancement of science and technology, self-service devices are becoming increasingly popular. Self-service / semi-automatic devices typically print or scan (photograph) bulky documents (such as passports, household registers, passbooks, and books) for archiving and post-processing. After processing one page, when another needs to be processed, the document is typically ejected, and the user manually turns the page before continuing, resulting in a low level of automation.

[0003] Automated solutions exist in the prior art, utilizing the difference in friction coefficient between pages generated by the rotation of a page-turning roller at the front end of the first page of a book to separate and turn the pages. However, in practice, factors such as damage, dirt, or creases in the pages themselves, or changes in ambient temperature and humidity, can disrupt the prerequisite for different friction coefficients between the pages, resulting in failed or extra pages being turned. This effectively disrupts the effective conditions of the friction wheel principle, making it difficult to guarantee the success rate and accuracy of page turning. Furthermore, in the prior art, the page-turning roller must remain stationary while turning the pages, and continue to transport the book forward after turning is complete, significantly impacting the efficiency of the entire workflow.

[0043] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0044] In the present invention, if there is a description of directions (up, down, left, right, front and back), it is only for the convenience of describing the technical solution of the present invention, and does not indicate or imply that the technical features referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0045] In this utility model, "several" means one or more, "multiple" means more than two, "greater than," "less than," "exceeds," etc. are understood to exclude the number itself; "above," "below," "within," etc. are understood to include the number itself.

[0046] In this utility model, unless otherwise expressly defined, terms such as "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection or electrical connection or mutual communication; and internal connection between two components or interaction between two components. Those skilled in the art can reasonably determine the specific meanings of these terms in this utility model based on the specific content of the technical solution.

[0047] in, Figure 1 The reference direction coordinate system of the embodiment of the present utility model is given below. Figure 1 The embodiment of the present invention is described with reference to the direction shown.

[0048] The embodiment of the present utility model provides a page turning device, which can be used in usage scenarios where pages of books such as passports, household registers, passbooks, and books need to be turned.

[0049] See also Figure 1 、 Figure 2 、 Figure 3The page turning device includes a conveying channel 100 and a page turning assembly 200. The conveying channel 100 extends along the conveying direction. During the page turning action, the book 300 is conveyed along the conveying channel 100, and the page turning is realized by the page turning assembly 200.

[0050] The page turning assembly 200 includes a roller shaft 201 and a page turning roller 202 arranged on the roller shaft 201. One or more page turning rollers 202 are arranged along the roller shaft 201. The page turning assembly 200 is arranged transversely relative to the conveying channel 100. For example, Figure 1 In the embodiment shown, the page turning assembly 200 is located above the conveying channel 100. The roller shaft 201 of the page turning assembly 200 is perpendicular to the conveying direction. The page turning roller 202 has a protrusion 203 that protrudes radially outward. The page turning roller 202 can rotate around the axis of the roller shaft 201 to rotate the protrusion 203 into or out of the conveying channel 100. The protrusion 203 is provided with an adhesive 204 for sticking the pages together. Figure 1 The page turning roller 202 , except for the protruding portion 203 , basically avoids the conveying channel 100 during the rotation process, while the protruding portion 203 rotates into or out of the conveying channel 100 during the rotation process to achieve cooperation with the book 300 in the conveying channel 100 .

[0051] Combine Figure 3 , the working process of the page turning device is as follows:

[0052] 1. The protruding portion 203 of the page turning roller 202 is located outside the conveying passage 100 , for example, in a standby position along the conveying direction of the book 300 ;

[0053] 2. The book 300 reaches the predetermined page turning position along the conveying channel 100, and the page turning roller 202 rotates clockwise to a certain value, such as 90 degrees, and adheres to the surface page 301 of the book 300; at this time, the conveyance of the book 300 does not stop;

[0054] 3. The page turning roller 202 is reset counterclockwise or rotated to a certain angle. At this time, the book 300 is conveyed synchronously, so there will be no problems such as wrinkles or pulling of the book 300.

[0055] 4. The book 300 continues to be conveyed, and the surface page 301 of the book 300 is separated from the page turning roller 202 by the pulling force of the conveying;

[0056] 5. When the surface pages 301 of the book 300 are completely detached, the page turning roller 202 has been reset or the reset action has not affected the efficiency of the entire workflow.

[0057] The present invention's technical solution abandons the prior art's use of a page-turning roller 202 for frictional page turning. Instead, it employs adhesive 204 disposed on the page-turning roller 202. Specifically, as the book 300 travels along the conveyor path 100, the page-turning roller 202 rotates about the axis of the roller shaft 201, and the adhesive 204 adheres to the surface pages 301 of the book 300 and then detaches, thereby achieving page turning. The present invention's technical solution is highly adaptable to paper and environmental conditions, simplifies the structure, and reduces costs. Furthermore, the book 300 does not need to be stopped during page turning; the page turning is accomplished by simply rotating the page-turning roller 202 a certain angle, significantly improving page turning efficiency.

[0058] The protrusion 203 of the page turning roller 202 may be directly formed by the body of the page turning roller 202 , or may be formed by installing a protruding structure on the page turning roller 202 .

[0059] In some embodiments, see Figure 2 The page turning roller 202 is provided with a rubber seat 205. The rubber seat 205 is formed by the radial outward protrusion of the page turning roller 202 to form a protrusion 203. The adhesive 204 is provided on the top of the rubber seat 205. In this embodiment, the rubber seat 205 serves as a mounting seat for the adhesive 204. On the other hand, with the help of the radial outward protrusion of the rubber seat 205, a reverse rubbing pre-page turning function can be realized. That is, before the page is turned, the surface page 301 of the book 300 is rubbed by the rubber seat 205 to better separate it from the second layer of pages. For details, see Figure 4 After the book 300 is transported to the page turning roller 202 , the page turning roller 202 rotates clockwise around the axis of the roller shaft 201 and then counterclockwise, using the rubber seat 205 to rub the surface pages 301 of the book 300 .

[0060] It is understandable that the rubber seat 205 and the adhesive 204 can be manufactured as one piece, or can be manufactured separately and then connected into one piece.

[0061] Further, in some embodiments, see Figure 2 The outer circumference of the page-turning roller 202 is provided with a first mounting groove and a second mounting groove extending axially. The first and second mounting grooves are staggered circumferentially and have a closed axial cross-section. The rubber seat 205 includes a first flange 206 mounted in the first mounting groove and a second flange 207 mounted in the second mounting groove. The first and second flanges 206 and 207 are located on either side of the rubber seat 205, providing stable positioning for the rubber seat 205. Furthermore, the flanges extending to either side gradually extend the rubber seat 205 radially outward, helping it to better perform its anti-rubbing and pre-page-turning function. Furthermore, the flange-and-mounting groove assembly structure provides a simpler structure and facilitates assembly and disassembly.

[0062] It is understandable that the rubber seat 205 can also be connected to the page turning roller 202 by bonding, screws, snaps, etc.

[0063] Further, see Figure 2 The top of the rubber seat 205 is provided with a cavity 208, and the adhesive 204 is disposed in the cavity 208. The adhesive 204 is flush with or protrudes from the top surface of the rubber seat 205. The adhesive 204 is located in the cavity 208, so that the adhesive 204 is effectively separated from the outer wall of the rubber seat 205, thereby preventing the anti-rubbing function of the rubber seat 205 and the adhesion function of the adhesive 204 from interfering with each other.

[0064] Figure 2 In the embodiment, the protrusion 203 is only provided on the rear side of the page-turning roller 202. In some embodiments, the protrusion 203 includes a first protrusion 203 and a second protrusion 203 symmetrically provided on both sides of the page-turning roller 202. For example, the protrusion 203 is provided on both the front and rear sides of the page-turning roller 202. With the help of the first protrusion 203 and the second protrusion 203 symmetrically provided on both sides of the page-turning roller 202, the pages of the book 300 conveyed from front to back in the conveying channel 100 can be turned, and the pages of the book 300 conveyed from back to front in the conveying channel 100 can also be turned, thereby further improving work efficiency.

[0065] In some embodiments, see Figure 1 The page turning device includes a first channel plate 101 and a second channel plate 102. The first channel plate 101 and the second channel plate 102 are arranged along the thickness direction of the book 300. The first channel plate 101 and the second channel plate 102 define a conveying channel 100 therebetween. The first channel plate 101 and the second channel plate 102 ensure that the opened book 300 is conveyed in a flat position, preventing it from flipping over and causing the page turning function to fail. The page turning assembly 200 is arranged on one side of the first channel plate 101. The first channel plate 101 is left empty at the position corresponding to the page turning assembly 200. The protrusion 203 of the page turning roller 202 can rotate into or out of the conveying channel 100 at the empty position, ensuring that the surface pages 301 of the book 300 can be turned at the empty position under the adhesion of the page turning roller 202.

[0066] Further, in some embodiments, see Figure 1The second channel plate 102 has a groove 103 at the position corresponding to the page turning assembly 200. The groove 103 extends perpendicular to the conveying direction. When the book 300 is conveyed to the groove 103, the protrusion 203 rotates into the conveying channel 100. The protrusion 203 of the page turning roller 202 presses the book 300 downward, causing the book 300 to sink into the groove 103, thereby bending at the groove 103. During this bending process, the different pages of the book 300 slip, which better separates the surface pages 301 of the book 300 from the second layer of pages, further improving the page turning success rate.

[0067] It is understandable that the conveying channel 100 can also be defined and formed by conveying rollers arranged in rows.

[0068] In some embodiments, see Figure 1 Along the conveying direction, a front guide plate 104 is provided at the front side of the page turning assembly 200. A front rotation axis 105, perpendicular to the conveying direction, is located at the front edge of the front guide plate 104. A rear guide plate 106 is provided at the rear side of the page turning assembly 200. A rear rotation axis 107, perpendicular to the conveying direction, is located at the rear edge of the rear guide plate 106. The front guide plate 104 and rear guide plate 106 are located at the front and rear sides of the page turning assembly 200, respectively, to prevent the booklet 300 from flipping upward at the vacant position on the first channel plate 101, thereby preventing the page turning function from failing. Furthermore, the front rotation axis 105 and rear rotation axis 107 work in conjunction with the page turning assembly 200 to provide clearance for stuck pages, ensuring smooth page turning.

[0069] In some embodiments, see Figure 1 The page turning device further includes a first conveyor roller 401 and a second conveyor roller 402. The first conveyor roller 401 and the second conveyor roller 402 are spaced a certain distance apart along the extension direction of the conveying passage 100. The spacing between the first conveyor roller 401 and the second conveyor roller 402 is required to ensure that the book 300 can be continuously conveyed therebetween in a relay-like manner. The page turning assembly 200 is disposed between the first conveyor roller 401 and the second conveyor roller 402. The first conveyor roller 401 and the second conveyor roller 402 can both be configured as a driving roller and a driven roller, with the driving roller and the driven roller clamping the book 300 for conveyance. The first conveyor roller 401 and the second conveyor roller 402 can both be configured as a driving roller and another driving roller, with the two driving rollers rotating in opposite directions and clamping the book 300 for conveyance.

[0070] An embodiment of the present utility model further provides a self-service device, comprising the page turning device in any of the above embodiments.

[0071] The embodiment of the present utility model also provides a page turning method, see Figure 3 , using the page turning device in any of the above embodiments, including the following steps:

[0072] The page turning roller 202 is located at the initial position, and the protruding portion 203 of the page turning roller 202 rotates out of the conveying channel 100;

[0073] The book 300 is conveyed along the conveying passage 100. After the book 300 reaches the page turning roller 202, the page turning roller 202 rotates a certain angle in the first direction around the axis of the roller shaft 201, so that the protrusion 203 moves into the conveying passage 100, and the adhesive 204 of the protrusion 203 contacts the surface page 301 of the book 300.

[0074] The page turning roller 202 rotates a certain angle in the second direction around the axis of the roller shaft 201, and the protrusion 203 rotates out of the conveying channel 100 and sticks the surface page 301 of the book 300;

[0075] The album 300 continues to be transported along the transport path 100 , and the surface pages 301 of the album 300 remain adhered to the adhesive 204 until the pulling force of the album 300 being transported causes the surface pages 301 of the album 300 to separate from the adhesive 204 .

[0076] The embodiment of the present invention also provides another method for turning pages. Figure 3 and Figure 4 , using the page turning device in any of the above embodiments, including the following steps:

[0077] The page turning roller 202 is located at the initial position, and the protruding portion 203 of the page turning roller 202 rotates out of the conveying channel 100;

[0078] The book 300 is transported along the transport passage 100. After the book 300 reaches the page turning roller 202, the page turning roller 202 rotates in a first direction and then in a second direction around the axis of the roller shaft 201, and rubs the surface pages 301 of the book 300 using the rubber seat 205.

[0079] The page turning roller 202 rotates around the axis of the roller shaft 201 along a first direction at a certain angle, so that the protrusion 203 moves into the conveying channel 100, and the adhesive 204 of the protrusion 203 contacts the surface page 301 of the book 300;

[0080] The page turning roller 202 rotates a certain angle in the second direction around the axis of the roller shaft 201, and the protrusion 203 rotates out of the conveying channel 100 and sticks the surface page 301 of the book 300;

[0081] The album 300 continues to be transported along the transport path 100 , and the surface pages 301 of the album 300 remain adhered to the adhesive 204 until the pulling force of the album 300 being transported causes the surface pages 301 of the album 300 to separate from the adhesive 204 .

[0082] The page turning method of this embodiment adds a reverse rubbing step, that is, before sticking and turning the pages, the surface pages 301 of the book 300 are rubbed by the rubber seat 205 to better separate them from the second layer of pages, further improving the page turning success rate.

[0083] The embodiment of the present invention also provides another method for turning pages. Figure 3 , using the page turning device in any of the above embodiments, including the following steps:

[0084] The page turning roller 202 is located at the initial position, and the protruding portion 203 of the page turning roller 202 rotates out of the conveying channel 100;

[0085] The book 300 is conveyed along the conveying passage 100. After the book 300 reaches the page turning roller 202, the page turning roller 202 rotates a certain angle in the first direction around the axis of the roller shaft 201, so that the protrusion 203 moves into the conveying passage 100, and the adhesive 204 of the protrusion 203 contacts the surface page 301 of the book 300.

[0086] The page turning roller 202 rotates a certain angle in the second direction around the axis of the roller shaft 201, and the protrusion 203 rotates out of the conveying channel 100 and sticks the surface page 301 of the book 300;

[0087] The book 300 continues to be transported along the transport passage 100 , and the surface pages 301 of the book 300 remain adhered to the adhesive 204 until the pulling force of the book 300 causes the surface pages 301 of the book 300 to separate from the adhesive 204 .

[0088] The page turning roller 202 rotates around the axis of the roller shaft 201 to exchange the positions of the first protruding portion 203 and the second protruding portion 203 .

[0089] The page turning method of this embodiment adds a step of swapping the positions of the first protrusion 203 and the second protrusion 203. That is, when the shapes or states of the adhesive 204 on the first protrusion 203 and the second protrusion 203 are different or one of them is not good, the front and rear protrusions 203 can be swapped after turning a certain number of pages.

[0090] In some embodiments, after the page-turning roller 202 rotates a certain angle in the second direction around the axis of the roller shaft 201, if the glue 204 fails to successfully stick to the surface page 301 of the book 300, the page-turning roller 202 rotates a certain angle in the first direction around the axis of the roller shaft 201 again, so that the protrusion 203 is turned into the conveying channel 100 again, and the glue 204 of the protrusion 203 contacts the surface page 301 of the book 300 again, that is, by detecting and performing the adhesion action multiple times, the page-turning success rate is further improved.

[0091] Throughout this specification, references to terms such as "example," "embodiment," or "some embodiments" indicate that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention.
