Description

Technical Field

[0001] This invention relates to the field of archival digitization equipment technology, specifically to an automatic page-turning scanning method for bound documents. Background Technology

[0002] With the advancement of digitalization in tobacco monopoly management, the scanning and conversion of massive amounts of paper monopoly files has become a fundamental step in digital review and auditing, leading to an increasingly urgent need for batch and efficient scanning of bound paper documents. In this process, enabling automatic page turning during scanning is a core technological step that replaces manual labor and improves overall operational efficiency and continuity.

[0003] Currently, automatic page turning mainly relies on two methods: one is completely manual operation, where operators manually turn each page, which is inefficient and has high labor costs; the other is the use of mechanical automatic page turning devices, which usually use mechanisms such as hard paddles, rollers or friction wheels to force page turning by directly contacting and scraping the edges of the page, which can easily cause page damage.

[0004] Therefore, existing technologies lack a solution that can easily integrate with conventional scanning equipment and achieve accurate, gentle, and reliable automatic page turning during the scanning process, thus overcoming a key bottleneck in the automated scanning workflow. To address the above issues, the applicant has designed an automatic page turning device, the specific structure of which is detailed in the specification and accompanying drawings.

[0005] However, although the device achieves automatic page turning in its structure, in practical applications, how to more effectively control the automatic page turning scanning method, optimize the coordination process between the page turning action and the scanning equipment, and improve the accuracy, stability and overall continuity of page turning are still technical problems that urgently need to be solved.

[0006] Therefore, this application aims to provide a highly efficient control method that matches the aforementioned automatic page-turning device, so as to further leverage its structural advantages and achieve truly automated, non-destructive, and highly efficient scanning of bound documents.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] To address the aforementioned technical problems, embodiments of the present invention provide an automatic page-turning scanning method for bound documents, thereby resolving the issues raised in the background section.

[0009] This invention provides the following technical solution: an automatic page-turning scanning method for bound documents, applied to an automatic page-turning device for bound documents; its specific steps include: S1: Place the bound document to be scanned flat under the automatic page-turning device, with the bound side of the document facing the side frame; initialize the control device and drive the sliding platform, along with the lifting unit and page-turning assembly, to move to the initial position away from the bound side; S2: Control the lifting unit to drive the page-turning component to descend, so that the suction cup is adjusted to a preset height close to the page to be turned; start the vacuum generator and open the solenoid valve to generate negative pressure in the suction cup and adsorb the page to be turned; S3: Control the lifting unit to drive the page turning component to rise, thereby lifting the page to be turned vertically and completely separating the page to be turned from the lower page. S4: Start the horizontal cylinder, its drive rod extends and drives the lifting unit and sliding platform to slide along the crossbeam, thereby driving the adsorbed pages to be turned to move horizontally towards the document binding side. S5: When the sliding platform moves to the preset position on the binding side, close the solenoid valve and stop the vacuum generator, so that the suction cup releases the page to be turned, completing a single page turn; then control the horizontal cylinder drive rod to retract, driving the sliding platform, lifting unit and page turning assembly to return to the initial position horizontally, while controlling the lifting unit to drive the page turning assembly to descend to the preset height for the next suction, completing one page turning cycle.

[0010] Preferably, after completing a single page turn in step S5, the method further includes step S6: controlling the scanning device to start and scanning the page exposed after the page turn; after the scan is completed, sending a feedback signal to the control system, and the control system triggering the next page turn action after receiving the signal, thereby realizing an automated collaborative cycle of page turn-scanning.

[0011] Preferably, the procedure also includes step S0, which is performed before step S1: fixing the bound documents to the scanning station using a magnetic book clip; and during page turning, flattening and fixing the paper using a left-side flattening device and / or a right-side fixing device to prevent the paper from shifting or curling.

[0012] Preferably, the left flattening device and / or right fixing device have the same structure, each including a flattening servo and a pressure plate that can be connected to the flattening servo, the flattening servo driving the pressure plate to rotate.

[0013] Preferably, the paper paging step is performed before step S2: the adhered or overlapping pages are pneumatically or vibratoryly separated by a suction cup to ensure that only a single page is suctioned at a time.

[0014] Preferably, the method also includes a paper flipping step after single-sided scanning: the bound documents are flipped over as a whole by a paper flipping device, and steps S1-S5 are repeated to achieve double-sided automatic scanning.

[0015] Preferably, the control system integrates a parameter preset module, allowing users to preset parameters such as adsorption time, lifting height, and sliding speed according to paper type, thickness, and size. The system then automatically calls the corresponding parameter combination to execute the page turning process.

[0016] The automatic page-turning scanning method for bound documents provided in this invention has the following beneficial effects: (1) The automatic page-turning and scanning method for bound documents provided by the present invention integrates the page-turning component with the slide rail mechanism, thereby realizing the automatic, accurate and non-destructive page turning of bound documents.

[0017] (2) The present invention adopts an automated timing control that includes adsorption, lifting, horizontal flipping, release and reset in sequence, which effectively replaces inefficient manual operation and significantly improves the continuity and overall efficiency of scanning operation.

[0018] (3) The present invention uses non-contact or micro-contact adsorption methods such as Bernoulli suction cups to avoid physical damage to paper and multi-page adhesion problems caused by traditional mechanical page turning.

[0019] (4) The present invention has a compact structure and strong adaptability. It can be easily integrated with conventional scanning equipment, which meets the urgent need of the field of archive digitization for efficient and reliable processing of large amounts of data.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The crossbeam 1-3 includes two parallel and spaced support beams 1-31 and 1-32; the gap between support beams 1-31 and 1-32 forms an assembly space. Both support beam 1-31 and support beam 2-32 are fixedly connected to guide rail 1-2 along their length; sliding platform 3 is slidably connected to the two guide rails 1-2 by a slider. The lifting unit is located in the assembly space between support beam 1-31 and support beam 2-32, and is fixedly connected to the bottom of the sliding platform 3; The horizontal cylinder 4 is fixed to one side of one of the side frames 1-1, and the drive rod of the horizontal cylinder 4 passes through the side frame 1-1 and is connected to the lifting unit for drive. The page-turning assembly includes a fixing plate 5-1 fixed to the lifting unit, and a suction cup 5-2 disposed on the fixing plate 5-1; The suction cup 5-2 is connected to the vacuum generator via a hose, and a solenoid valve is connected in series between the suction cup 5-2 and the vacuum generator.

[0023] In this embodiment, the lifting unit includes a lifting assembly 7 and a vertical cylinder 6 that drives the lifting assembly 7 to lift.
