[0002] In the book printing and binding process, a page feeding device is used to transport stacks of pages with the same page number and distribute them into individual pages for subsequent page binding processes. However, in related technologies, the page feeding device has the problem of not being able to repeatedly break up and reshape the stacks of pages during the feeding process. This can lead to delays in the subsequent collating process due to misaligned pages. Furthermore, current page feeding devices are single conveyor lines, which can only transport a single page number. When multiple page numbers need to be transported, multiple page feeding devices are required, which occupies a significant amount of space. Summary of the Invention

Detailed Implementation

[0021] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

[0022] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0024] When a component is said to be "connected to" another component, it can be directly connected to the other component or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0028] Please refer to the following: Figures 1 to 7 The following describes a page feeding device provided in an embodiment of this application.

[0029] It is understood that the page feeding device described in the embodiments of this application includes at least one set of page feeding lines 10. The page feeding line 10 is connected to the page stack conveying device and the collating line, and is used to break up several pages with the same content on the page stack so that only a single page enters the collating line at a time, thereby avoiding misaligned and disordered pages during the collating process.

[0030] refer to Figure 1 , Figure 2 and Figure 4 It is understood that each conveying line 10 includes a first conveying section 11, a second conveying section 12, and a third conveying section 13 that are disposed on the frame and connected sequentially at least in the length direction. The infeed section of the third conveying section 13 is inclined upward relative to the discharge section of the second conveying section 12, and the conveying speed of adjacent two conveying sections is equal or increases sequentially in the direction of conveying. Preferably, the conveying speed of each conveying section increases sequentially in the direction of conveying.

[0031] The first conveying section 11 is used to convey stacks of pages, the second conveying section 12 is used to disperse the stacks of pages along the conveying direction, and the third conveying section 13 is used to convey each page in the dispersed stacks of pages to the collating conveying line.

[0032] By sequentially increasing the conveying speeds of the first conveying section 11, the second conveying section 12, and the third conveying section 13 in the direction of conveying, the sheets at the bottom of the stack can be pulled off the stack at a higher speed during the transition from the first conveying section 11 to the second conveying section 12. This allows each sheet of paper on the stack to enter the second conveying section 12 at an angle. During the transition from the second conveying section 12 to the third conveying section 13, the angled arrangement of the third conveying section 13 allows the sheets at the bottom of the inclined stack to be fully pulled off the stack and enter the third conveying section 13 individually. This avoids situations where sheets are incomplete, the machine stops, or the stack cannot be bound or is missing from binding in subsequent collating processes.

[0033] The first conveyor section 11 can be a conveyor belt plane, the second conveyor belt 141 can be a conveyor belt plane, and the third conveyor section 13 can also be a conveyor belt plane.

[0034] Each conveyor section is connected to a motor 16 on the frame via a first synchronous belt mechanism 15 and is driven by the motor 16. It can be understood that each conveyor section can be driven by a separate motor 16 to achieve paper conveying; that is, each first synchronous belt mechanism 15 is driven by a single motor 16. Alternatively, only one motor 16 can be provided, which synchronously drives each first synchronous belt mechanism 15 to enable paper conveying in each conveyor section.

[0035] In some embodiments, the page feed line 10 in the page feed device is arranged in at least two sets side by side in the width or length direction. By arranging the page feed lines 10 in this way, the footprint of the page feed device can be minimized while increasing the number of page types, thereby improving the site adaptability of the equipment.

[0036] In the first embodiment, the page feed line 10 is provided with at least two sets in the height direction.

[0037] In the second embodiment, the page feed line 10 is provided with at least two sets in the width direction.

[0038] refer to Figures 1 to 7 In the third embodiment, the page feed lines 10 are arranged side by side in both the width and height directions. For example, two sets are arranged side by side in the width direction and three sets are arranged side by side in the height direction, that is, six sets of page feed lines 10 are provided in the same page feed device.

[0039] Furthermore, in a further embodiment, the aforementioned first synchronous belt mechanism 15 may have the following several implementations.

[0040] refer to Figure 3 , Figure 5 and Figure 6The first embodiment is adapted to the first embodiment of the aforementioned page feeding line 10. Specifically, each conveying segment in different page feeding lines 10 and located in the same height direction is connected to the motor 16 through the same first synchronous belt mechanism 15 for synchronous linkage. It can be understood that in this embodiment, there may be only one motor 16 or multiple motors 16. In the case of multiple motors 16, the number of motors 16 is the same as the number of first synchronous belt mechanisms 15. Each motor 16 drives each first synchronous belt mechanism 15 to transmit power, thereby enabling the same conveying segment at different height levels to be conveyed synchronously.

[0041] refer to Figure 3 , Figure 5 and Figure 6 The second implementation method is adapted to the second implementation method of the aforementioned page feeding line 10. Specifically, in two adjacent sets of page feeding lines 10 arranged side by side in the width direction, each conveying section is individually connected to the motor 16 with a first synchronous belt mechanism 15, wherein each first synchronous belt mechanism 15 connected to each conveying section is linked together.

[0042] refer to Figure 3 , Figure 5 and Figure 6 The third implementation method is adapted to the third implementation method of the aforementioned page feeder 10. That is, in different page feeders 10, each conveying segment located in the same height direction is connected to the motor 16 through the same first synchronous belt mechanism 15 for synchronous linkage; and in two adjacent sets of page feeders 10 arranged side by side in the width direction, each conveying segment is individually connected to the motor 16 with a first synchronous belt mechanism 15, wherein each first synchronous belt mechanism 15 connected to each conveying segment is linked. That is, for each page feeder 10, each identical conveying segment (e.g., the first conveying segment 11, the second conveying segment 12, or the third conveying segment 13) in different page feeders 10 only needs one motor 16 to drive multiple identical conveying segments (e.g., the first conveying segment 11, the second conveying segment 12, or the third conveying segment 13) to achieve synchronous transmission. Specifically, taking this application as an example, when the page feeder 10 includes three conveying segments, only three motors 16 are needed to drive the transmission of all conveying segments in each page feeder 10.

[0043] Understandably, reference Figure 3 , Figure 5 and Figure 6The first synchronous belt mechanism 15 in each of the aforementioned embodiments includes a driving pulley 171, a driven pulley 172, a tensioning pulley 173, and a synchronous belt 174 wound between each driving pulley 171, driven pulley 172, and tensioning pulley 173. The driving pulley 171 is connected to the output shaft of the motor 16; the number of driven pulleys 172 is the same as the number of conveyor lines 10 arranged in the height direction, and the driven pulleys 172 are connected to the conveyor rollers of each conveyor line via rotating shafts to drive the conveyor rollers to rotate; the number of tensioning pulleys 173 depends on the specific situation, and the tensioning pulleys 173 are used to keep the synchronous belt 174 taut.

[0044] It is understood that, based on the foregoing embodiments, the first synchronous belt mechanism 15 may have the following further embodiments. This embodiment applies to the foregoing embodiment in which the feed lines 10 are arranged side by side in the width direction.

[0045] Specifically, in the width direction, an electromagnetic clutch 175 is connected between two adjacent sets of first synchronous belt mechanisms 15. For example, the electromagnetic clutch 175 is disposed in the drive pulley 171 of each first synchronous belt mechanism 15 so that two first synchronous belt mechanisms 15 arranged side by side in the width direction can be driven synchronously or asynchronously.

[0046] Or, refer to Figure 6 An electromagnetic clutch 175 is connected between each pair of adjacent first synchronous belt mechanisms 15 and at each corresponding height position of the conveying section; that is, in the same first synchronous belt mechanism 15, the electromagnetic clutch 175 is connected between the driven wheel 172 and the conveying roller to control the conveying roller in each conveying section to rotate synchronously or asynchronously with the first synchronous belt 174.

[0047] By setting an electromagnetic clutch 175 in the first synchronous belt mechanism 15, two first synchronous belt mechanisms 15 arranged side by side in the width direction, or the same conveying sections at different height positions in the same height direction, can be driven synchronously or asynchronously. For a type of conveying section, only one motor 16 is needed to achieve synchronous or asynchronous transmission of each conveying section.

[0048] refer to Figures 1 to 6 In some embodiments, the page feeding device further includes a fourth conveying section 14, which is horizontally arranged and connected to the discharge section of the third conveying section 13. A baffle mechanism is provided on the fourth conveying section 14, and the fourth conveying section 14 is connected to the collating line. By providing a baffle mechanism on the fourth conveying section 14, it can be ensured that only one sheet of paper enters the collating line each time, thereby further avoiding the occurrence of duplicate or incorrect page numbers during collating.

[0049] Specifically, the third conveyor section 13 and the fourth conveyor section 14 are configured to operate at the same speed and in conjunction with each other. A second synchronous belt mechanism 17 is connected between the first synchronous belt mechanism 15 of the third conveyor section 13 and the first synchronous belt mechanism 15 of the fourth conveyor section 14. It is understood that an electromagnetic clutch 175 can also be provided in the second synchronous belt mechanism 17, and the specific arrangement is consistent with the arrangement of the electromagnetic clutch 175 in the first synchronous belt mechanism 15.

[0050] Specifically, refer to Figure 5 and Figure 6 The fourth conveying section 14 includes several conveyor belts 141 arranged side-by-side and spaced apart in the width direction of the conveying plane; the blocking mechanism includes a pushing mechanism 142 mounted on the frame and a blocking plate 143 mounted on the driving end of the pushing mechanism 142, the blocking plate 143 passing through the gap between two adjacent conveyor belts 141; wherein, the pushing mechanism 142 may be a cylinder. When it is necessary to convey the paper to the collating line, the pushing mechanism 142 drives the blocking plate 143 to retract below the conveying plane of the fourth conveying section 14; when it is necessary to block the conveying of the paper, the pushing mechanism 142 drives the blocking plate 143 to move above the conveying plane of the fourth conveying section 14.

[0051] refer to Figure 5 In some embodiments, an air blowing mechanism 18 is provided between the second conveying section 12 and the third conveying section 13. The air blowing mechanism 18 is used to blow air into the gap between the second conveying section 12 and the third conveying section 13. The air blowing mechanism 18 includes several nozzles connected to a compressed air source. By providing the air blowing mechanism 18, the sheets of paper entering the third conveying section 13 from the second conveying section 12 can be fully separated from the stack under the action of airflow, so as to ensure that only one sheet of paper enters the third conveying section 13 at a time.

[0052] Furthermore, each air nozzle is located at the bottom of the second conveying section 12 and blows air towards the conveying plane of the third conveying section 13. Under the guidance of the conveying plane of the third conveying section 13, the airflow can be blown from bottom to top through the gap between the second conveying section 12 and the third conveying section 13 to achieve a better paper separation effect.

[0053] refer to Figure 1 In some embodiments, the second conveying section 12 includes a first segment 121 and a second segment 122 that are synchronously arranged. One end of the second segment 122 is rotatably arranged so that its height is adjustable so that it is close to one end of the third conveying section 13. Since the second segment 122 is connected to the third conveying section 13, by rotating the second segment 122, the height position at the connection between the second conveying section 12 and the third conveying section 13 can be adjusted so that the paper can be separated from the stack more smoothly.

[0054] Specifically, the second conveying section 12 includes a rotating frame rotatably mounted on the frame body. A first roller 1201 and several second rollers 1202 are respectively mounted at both ends of the rotating frame. The rotating frame can rotate relative to the first roller 1201. A first synchronous belt mechanism 15 driving the second conveying section 12 is connected to the first roller 1201. A third roller 1203 is rotatably mounted on the frame body. The conveyor belt on the first section 121 is wound between the third roller 1203 and the first roller 1201. The conveyor belt on the second section 122 is wound between the first roller 1201 and each of the second rollers 1202, and the conveyor belts on the first section 121 and the second section 122 are staggered. It is understood that the width of each conveyor belt on the first section 121 and the second section 122 is smaller than the width of each conveyor belt on the first conveying section 11 and the third conveying section 13. By configuring the second conveyor section 12 in this way, only a single first synchronous belt mechanism 15 is needed to achieve synchronous drive of the first section 121 and the second section 122. Furthermore, configuring the conveyor belts of the first section 121 and the second section 122 in this way also allows the airflow of the air blowing mechanism 18 on the frame to be better guided from the gap between the second conveyor section 12 and the third conveyor section 13 to the area above the connection between the second conveyor section 12 and the third conveyor section 13.

[0055] refer to Figure 2 In some embodiments, a pressing assembly 19 is provided on the third conveying section 13. The pressing assembly 19 includes a pressing frame 191 arranged parallel to the third conveying section 13 and a pressing wheel 192 rotatably arranged on the pressing frame 191. By providing the pressing assembly 19, when a single sheet of paper is conveyed at an angle upward on the transmission plane of the third conveying section 13, the pressing wheel 192 can prevent the paper from sliding backward on the conveying plane due to gravity.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
