Description

Technical Field

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

[0002] With the development of science and technology, self-service equipment is increasingly widely used. Self-service / semi-automatic equipment usually needs to print or scan (photograph) some book-type documents (such as passports, household registers, passbooks, books, etc.) for archiving and post-processing. After one page is processed, when another page needs to be processed, the file usually needs to be exited, and the user manually turns the page before continuing to process the next page. The degree of automation is low.

[0003] There are also automated solutions in the prior art, which use the difference in friction coefficient between pages generated when the page-turning roller rotates at the front end of the first page of the book to separate the first page and turn the page. However, in actual applications, the paper itself is damaged, dirty, creased, or the temperature and humidity of the environment change, which destroys the prerequisite of different friction coefficients between the papers, resulting in failure to turn the page or multiple pages being turned. That is, the effective conditions of the friction wheel principle are easily destroyed, and the success rate and accuracy of page turning cannot be effectively guaranteed. Moreover, in the prior art, when the page-turning roller performs the page turning action, the book needs to remain stationary and continue to be transported forward after the page turning is completed, which greatly affects the efficiency of the entire workflow.

[0043] in, Figure 1 The reference direction coordinate system of the embodiment of the present invention is given. Figure 1 The embodiment of the present invention is described with reference to the direction shown.

[0044] The embodiment of the present invention 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.

[0045] See also Figure 1 , Figure 2 , Figure 3 The 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.

[0046] The page turning assembly 200 includes a roller shaft 201 and a page turning roller 202 disposed on the roller shaft 201. One or more page turning rollers 202 are disposed along the roller shaft 201. The page turning assembly 200 is disposed transversely relative to the conveying channel 100. Figure 1 In the illustrated embodiment, the page turning assembly 200 is located above the conveying passage 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 protruding outward in the radial direction, the page turning roller 202 can rotate around the axis of the roller shaft 201, so that the protrusion 203 is rotated into or out of the conveying passage 100, and the protrusion 203 is provided with an adhesive 204 for sticking pages together. Figure 1The page turning roller 202 , except for the protruding portion 203 , basically avoids the conveying passage 100 during the rotation process, while the protruding portion 203 rotates into or out of the conveying passage 100 during the rotation process to achieve cooperation with the book 300 in the conveying passage 100 .

[0047] Combination Figure 3 , the working process of the page turning device is as follows:

[0048] 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 ;

[0049] 2. The book 300 reaches the predetermined page turning position along the conveying passage 100, and the page turning roller 202 rotates clockwise to a certain value, such as 90°, and adheres to the surface page 301 of the book 300; at this time, the conveying of the book 300 does not stop;

[0050] 3. The page turning roller 202 is reset counterclockwise or to a certain angle, and the book 300 is conveyed synchronously, so the book 300 will not be wrinkled or pulled;

[0051] 4. The book 300 continues to be transported, and the surface page 301 of the book 300 is separated from the page turning roller 202 by the pulling force of the transport;

[0052] 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.

[0053] In the technical solution of the present invention, the technical solution of turning pages by friction of the page-turning roller 202 in the prior art is abandoned, and the technical solution of setting the adhesive 204 on the page-turning roller 202 is adopted, that is, when the book 300 is conveyed along the conveying channel 100, the page-turning roller 202 rotates around the axis of the roller shaft 201, and the surface pages 301 of the book 300 are further adhered by the adhesive 204 and then separated, so as to realize the page-turning function. The technical solution of the present invention has strong adaptability to the conditions of paper and environment, simplifies the structure, reduces the cost, and the book 300 does not need to stop conveying during the page-turning process, and the page-turning roller 202 only needs to rotate a certain angle to complete the page-turning, which greatly improves the efficiency of page-turning.

[0054] 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 protrusion structure on the page turning roller 202 .

[0055] In some embodiments, see Figure 2The 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 arranged on the top of the rubber seat 205. In this embodiment, the rubber seat 205 is used as a mounting seat for the adhesive 204 on the one hand. On the other hand, with the help of the radial outward protrusion of the rubber seat 205, the reverse rubbing pre-page turning function can also be realized, that is, before the adhesion and page turning, the surface page 301 of the book 300 is first rubbed by the rubber seat 205 to make it better pre-separated 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, and rubs the surface pages 301 of the book 300 using the rubber seat 205 .

[0056] 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 as one piece.

[0057] Further, in some embodiments, see Figure 2 The outer peripheral surface of the page turning roller 202 is provided with a first mounting groove and a second mounting groove extending in the axial direction, the first mounting groove and the second mounting groove are staggered in the circumferential direction, and the first mounting groove and the second mounting groove have a closed axial cross section, and the rubber seat 205 has a first flange 206 assembled in the first mounting groove and a second flange 207 assembled in the second mounting groove. The first flange 206 and the second flange 207 are located on the two side edges of the rubber seat 205, which can provide stable positioning for the rubber seat 205, and by means of the flanges extending to both sides, the rubber seat 205 gradually extends radially outward, which helps the rubber seat 205 to better play the anti-rubbing pre-page turning function. At the same time, the assembly structure of the flange and the mounting groove is adopted, and the structure is simpler and the disassembly and assembly are more convenient.

[0058] It is understandable that the rubber seat 205 can also be connected to the page turning roller 202 by bonding, screws, buckles, etc.

[0059] Further, see Figure 2 The top of the rubber seat 205 is provided with a cavity 208, and the adhesive 204 is arranged in the cavity 208, and the adhesive 204 is flush with the top surface of the rubber seat 205 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 surface of the rubber seat 205, avoiding the anti-rubbing function of the rubber seat 205 and the adhesion function of the adhesive 204 from interfering with each other.

[0060] Figure 2In 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 the work efficiency.

[0061] In some embodiments, see Figure 1 The page turning device includes a first channel plate 101 and a second channel plate 102, which are arranged along the thickness direction of the book 300, and define a conveying channel 100 between the first channel plate 101 and the second channel plate 102. The first channel plate 101 and the second channel plate 102 can ensure that the opened book 300 is conveyed in a flat posture, so as to avoid the page turning function being invalid due to opening to the top. The page turning assembly 200 is arranged on the side where the first channel plate 101 is located, and the first channel plate 101 is left empty at the position corresponding to the page turning assembly 200, and the protrusion 203 of the page turning roller 202 can be turned into or out of the conveying channel 100 at the empty position, so as to ensure that the surface page 301 of the book 300 can be turned at the empty position under the adhesion of the page turning roller 202.

[0062] Further, in some embodiments, see Figure 1 The second channel plate 102 is provided with a groove 103 at a position corresponding to the page turning assembly 200, and the groove 103 extends in a direction perpendicular to the conveying direction. When the book 300 is conveyed to the position of the groove 103, the protrusion 203 turns into the conveying channel 100, and the protrusion 203 of the page turning roller 202 presses the book 300 downward, and makes the book 300 sink into the groove 103, so that it bends at the groove 103. During the bending process, different pages of the book 300 slip, so that the surface page 301 of the book 300 is better pre-separated from the second layer page, further improving the page turning success rate.

[0063] It is understandable that the conveying channel 100 can also be defined and formed by conveying rollers arranged in rows.

[0064] In some embodiments, see Figure 1A front guide plate 104 is provided at the front side of the page turning assembly 200 along the conveying direction, a front rotating shaft 105 perpendicular to the conveying direction is provided at the front edge of the front guide plate 104, and a rear guide plate 106 is provided at the rear side of the page turning assembly 200, and a rear rotating shaft 107 perpendicular to the conveying direction is provided at the rear edge of the rear guide plate 106. The front guide plate 104 and the rear guide plate 106 are respectively located at the front and rear sides of the page turning assembly 200, and are used to prevent the book 300 from turning to the top at the empty position of the first channel plate 101, which causes the page turning function to fail. At the same time, with the help of the front rotating shaft 105 and the rear rotating shaft 107, it can cooperate with the page turning assembly 200 to provide avoidance for the adhered pages, so as to ensure that the page turning function can be carried out smoothly.

[0065] In some embodiments, see Figure 1 The page turning device also includes a first conveying roller 401 and a second conveying roller 402. The first conveying roller 401 and the second conveying roller 402 are spaced a certain distance apart along the extension direction of the conveying passage 100. The spacing between the first conveying roller 401 and the second conveying roller 402 needs to ensure that the book 300 can be continuously conveyed in a relay manner therebetween. The page turning assembly 200 is disposed between the first conveying roller 401 and the second conveying roller 402. The first conveying roller 401 and the second conveying roller 402 can both use an active roller and a driven roller, and the active roller and the driven roller clamp the book 300 for conveying. The first conveying roller 401 and the second conveying roller 402 can both use an active roller and another active roller, and the two active rollers rotate in opposite directions and clamp the book 300 for conveying.

[0066] An embodiment of the present invention further provides a self-service device, comprising the page turning device in any of the above embodiments.

[0067] The embodiment of the present invention also provides a page turning method, see Figure 3 , using the page turning device in any of the above embodiments, including the following steps:

[0068] 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 passage 100;

[0069] The book 300 is transported along the transport passage 100. After the book 300 is transported to the page turning roller 202, the page turning roller 202 rotates a certain angle along the first direction around the axis of the roller shaft 201, so that the protrusion 203 is transferred into the transport passage 100, and the adhesive 204 of the protrusion 203 contacts the surface page 301 of the book 300.

[0070] The page turning roller 202 rotates a certain angle along 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;

[0071] 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 transport of the book 300 causes the surface pages 301 of the book 300 to separate from the adhesive 204 .

[0072] The embodiment of the present invention also provides another page turning method, see Figure 3 and Figure 4 , using the page turning device in any of the above embodiments, including the following steps:

[0073] 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 passage 100;

[0074] The book 300 is transported along the transport passage 100. After the book 300 is transported to the page turning roller 202, the page turning roller 202 rotates along the first direction and then along the second direction around the axis of the roller shaft 201, and rubs the surface pages 301 of the book 300 by using the rubber seat 205.

[0075] The page turning roller 202 rotates a certain angle along the first direction around the axis of the roller shaft 201, so that the protrusion 203 turns into the conveying channel 100, and the adhesive 204 of the protrusion 203 contacts the surface page 301 of the book 300;

[0076] The page turning roller 202 rotates a certain angle along 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;

[0077] 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 transport of the book 300 causes the surface pages 301 of the book 300 to separate from the adhesive 204 .

[0078] 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.

[0079] The embodiment of the present invention also provides another page turning method, see Figure 3 , using the page turning device in any of the above embodiments, including the following steps:

[0080] 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 passage 100;

[0081] The book 300 is transported along the transport passage 100. After the book 300 is transported to the page turning roller 202, the page turning roller 202 rotates a certain angle along the first direction around the axis of the roller shaft 201, so that the protrusion 203 is transferred into the transport passage 100, and the adhesive 204 of the protrusion 203 contacts the surface page 301 of the book 300.

[0082] The page turning roller 202 rotates a certain angle along 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;

[0083] 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 being transported causes the surface pages 301 of the book 300 to separate from the adhesive 204 ;

[0084] 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 .

[0085] The page turning method of this embodiment adds a step of exchanging the positions of the first protrusion 203 and the second protrusion 203, that is, when the shapes or states of the adhesive 204 of 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.

[0086] In some embodiments, after the page turning roller 202 rotates a certain angle along 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 along the first direction around the axis of the roller shaft 201 again, so that the protrusion 203 is transferred 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.
