Description

Technical Field

[0001] The present disclosure relates to the field of scanning technology, and in particular to a page turning device and a scanning device with a smoothing device. Background Art

[0002] For scanners with automatic page turning capabilities, page turning accuracy and scanning efficiency are crucial. During actual page turning scanning, as the number of pages turned increases, bulging can easily appear near the spine of the page. To eliminate this bulging, the scanned object, such as a book, can be rotated along its spine during continuous page turning, thereby reducing the bulging.

[0003] However, during the rotation of the book spine, a bulge may easily appear at the root of the unturned part.

[0004] If the bulging phenomenon that occurs during the scanning process is not eliminated, the following problems will occur:

[0005] 1. The base of the unturned part of the page bulges, causing the edge of the page to move relative to the normal position. The adsorption position of the suction cup installed in the page turning device changes compared to the predetermined position, and it may be adsorbed to the edge of the page being turned, which may cause air leakage and lead to page turning failure.

[0006] 2. Due to the bulging phenomenon, the edge of the book page shifts to the left momentarily relative to the normal state, and the page pressing mechanism used to press the unturned pages is pressed empty, causing the system to receive incorrect information, which further leads to excessive adjustments in subsequent operations such as anti-rebound and spine rotation, thereby causing the entire scanning process to fail.

[0007] 3. The bulging phenomenon will affect the photo effect.

[0008] These resulting issues may ultimately lead to scan failures. Summary of the Invention

[0037] Overall configuration

[0038] First, refer to Figure 1 , describes the overall configuration of the scanning device 100 according to an embodiment of the present disclosure. Figure 1As shown, the scanning device 100 according to an embodiment of the present disclosure includes a supporting device 110, a holding device 120, a paging device 130, a page turning device 140, an imaging device 150, and an anti-rebound device 160. In addition, the scanning device 100 according to the present disclosure also includes a controller 200, and the controller 200 includes a central processing unit (CPU) 201 as a control unit.

[0039] The controller 200 also includes a read-only memory (ROM) 202, a random access memory (RAM) 203, and a hard disk drive (HDD) 204. Furthermore, the controller 200 includes an interface 205. The ROM 202, the RAM 203, the HDD 204, and the interface 205 are connected to the CPU 201 via a bus. A basic program for causing the CPU 201 to operate is stored in the ROM 202. The RAM 203 is a storage device in which various data such as the calculation processing results of the CPU 201 are temporarily stored. The HDD 204 is a storage device in which the calculation processing results of the CPU 201, image data acquired by the imaging device 150, and the like are stored, and is also used to record therein programs for causing the CPU 201 to execute various controls.

[0040] The CPU 201 controls the operations of the supporting device 110 , the gripping device 120 , the sorting device 130 , the page turning device 140 , the imaging device 150 , and the anti-rebound device 160 by following a program recorded in the HDD 204 .

[0041] Next, refer to Figure 2 , the various components of the scanning device 100 according to the present disclosure are described in conjunction with the scanning process. Figure 2 In, with Figure 1 Like reference numerals denote like parts, and when a part is composed of multiple parts, the same reference numerals are used. Figure 1 The reference numerals in the figure are suffixed with numbers 1, 2, 3, etc. to indicate the various parts that constitute the component. For example, reference numerals 1301, 1302, ..., 1305 indicate the various parts of the paging device 130. When a single part, such as 1303, is composed of multiple components, each component is indicated by the last three digits of the reference numeral of the part plus a suffix number, such as 3031 and 3032. The above-mentioned naming convention for reference numerals also applies to the subsequent figures.

[0042] It should be noted that in the following description, the term "scanned object" refers to a medium on which information can be recorded. The information recorded on the scanned object is converted into digital information through the scanning operation of a scanning device. Examples of scanned objects include plain paper, coated paper, plastic sheets, and the like. Furthermore, while the following description uses book pages as an example of a scanned object, the scanned object may also be, for example, a newspaper, a photograph, and the like.

[0043] In addition, in the following description, the length direction of the support device 110 of the scanning device 100 is defined as the X direction, the direction perpendicular to the plane where the support device 110 is located is defined as the Z direction (not shown), and the direction perpendicular to the XZ plane is defined as the Y direction.

[0044] like Figure 2 As shown, the scanning device 100 according to the present disclosure includes a supporting device 110, which is placed on a platform such as a table in a fixed and / or movably manner. A book 180 as a scanning object is supported on the supporting device 110. In order to facilitate subsequent scanning operations, one side (e.g., the spine) of the book 180 can be fixed to the supporting device 110 by a holding device 120. The holding device 110 is, for example, a clamping device, which fixes the book 180 to the surface of the supporting device 110 by, for example, clamping the spine of the book 180. Alternatively, in the case where the book 180 is a non-book document, the holding device 110 can fix the scanning object by aligning the document and clamping one side of the non-book document.

[0045] like Figure 2 As shown, the page turning device 140 according to an embodiment of the present disclosure includes a driving structure movement device 1401, a position adjustment device 1402 and a page bending adsorption structure support device 1403.

[0046] In addition, the paging device 130 according to the embodiment of the present disclosure includes a page bending adsorption structure 1301 , a non-bending page adsorption structure 1302 , an air blowing and pressing device 1303 , an adsorption force generating device 1304 and a pipe 1305 .

[0047] The air blowing and page pressing device 1303 includes a wind generating device 3031 and an air blowing port 3032 .

[0048] The non-bending page adsorption structure 1302 is a adsorption structure designed for paper with relatively high hardness. For the convenience of description, the page bending adsorption structure 1301 and the non-bending page adsorption structure 1302 are collectively referred to as adsorption structures below.

[0049] As shown in the figure, the page bending adsorption structure 1301 and the non-bending page adsorption structure 1302 are set as an integral body and are connected to the driving structure movement device 1401 through the page bending adsorption structure support device 1403. Specifically, the adsorption structures 1301 and 1302 are fixed to the page bending adsorption structure support device 1403, and the page bending adsorption structure support device 1403 can move along the slide rail provided on the driving structure movement device 1401. The slide rail is set at a predetermined angle relative to the XY plane. When the page bending adsorption structure support device 1403 moves along the slide rail, the adsorption structures 1301 and 1302 are driven to move along the direction of the slide rail. In addition, the position of the entire driving structure movement device 1401 in the Z direction can be adjusted by the position adjustment device 1402, thereby adjusting the initial position of the adsorption structures 1301 and 1302 in the Z direction.

[0050] In addition, the suction force generated by the suction force generating device 1304 of the paging device 130, such as negative pressure suction force, is transmitted to the suction structures 1301 and 1302 via the pipe 1305. The suction structures 1301 and 1302 are provided with suction cups. When the suction cups come into contact with the paper, suction force is generated on the paper.

[0051] Specifically, once the book 180 is moved to the scanning starting position along with the support device 110, the adsorption structures 1301 and 1302 bend along the slide rail on the driving structure movement device 1401 as the page bends, and when it moves to the position where it contacts the top layer of paper in the book 180, the adsorption force generating device 1304 generates a negative pressure adsorption force, which is transmitted to the suction cups provided on the adsorption structures 1301 and 1302 via the pipe 1305, and the top layer of paper is adsorbed by the suction cups.

[0052] Once attracted, the page bending adsorption structure support device 1403 moves upward along the slide rail on the driving structure movement device 1401, thereby separating the top sheet of paper from the subsequent sheet of paper by an angle. When the separation angle reaches a predetermined value, the back of the top sheet of paper and the front of the subsequent sheet of paper are simultaneously imaged by the provided cameras 1501 and 1502, and the captured images are converted into digital information through subsequent processing. During this process, in order to better separate the top sheet of paper from the subsequent sheet of paper, the wind force generating device 3031 of the blowing and pressing device 1303 can generate wind force, which is blown through the blowing port 515 of the blowing and pressing device 1303 to press the subsequent sheet of paper, thereby achieving better separation.

[0053] Simultaneously with or after the imaging operation, anti-rebound devices 1601 and 1602, located on either side of the book 180, press down on the turned paper, preventing it from rebounding, thus facilitating the next page turning. Specifically, anti-rebound devices 1601 and 1602 each include a rotating device 6012 / 6022 and a rotating device position adjustment device 6011 / 6021. Rotating devices 6012 / 6022 are arranged in a "Z" shape, with one end fixed to the rotating device position adjustment device 6011 / 6021 at an adjustable height. Rotating devices 6012 / 6022 rotate, allowing their other end to press down on the turned paper, preventing it from rebounding. This completes the page turning and imaging operations for a single sheet of paper.

[0054] By repeating the above operation process, continuous page turning and imaging operations on the book 180 can be achieved.

[0055] In the above description, although the present disclosure is described in terms of a specific form of the supporting device 110, the holding device 120, the paging device 130, the page turning device 140, the imaging device 150 and the anti-rebound device 160, the present disclosure is not limited thereto, but may adopt various other forms as long as the adopted form can realize the functions of the various components.

[0056] For example, while the adsorption force generating device 1304 is described using a vacuum adsorption device as an example, the adsorption force generating device 1304 is not limited to this and may include, for example, one or more of an electrostatic adsorption device, a magnetic adsorption device, or a biomimetic adsorption device. Furthermore, the generated force is not limited to an adsorption force and may also be a thrust applied to the paper. That is, in this disclosure, the adsorption force generating device 1304 is merely an example of a separation force generating device configured to generate a separation force that separates adjacent scanned objects.

[0057] In addition, the equipment for assisting paging is not limited to the air blowing and paging device 1303, but mechanical paging equipment, negative pressure page suction equipment, etc. can also be used, as long as these devices can play the role of assisting paging.

[0058] The various forms and settings of the supporting device 110, holding device 120, paging device 130, page turning device 140, imaging device 150 and anti-rebound device 160 disclosed in the present invention are specifically described in patent CN201721385718.2 owned by the applicant, and the entire content of the patent is incorporated herein by reference.

[0059] In addition, although in the above description, the paging device 130 is described as including the non-bending page adsorption structure 1302 and the air blowing and pressing device 1303, these components can be omitted without affecting the overall function of the scanning device 100.

[0060] In addition, in the reference Figure 2 In the description, the page turning device 140 and the paging device 130 are described as separate components, but it should be understood that the page turning device 140 and the paging device 130 can be Figure 2 The page turning device 140 and the paging device 130 shown in FIG. 1 are included in the category of the page turning device 140 .

[0061] As described above, during the page turning scanning process, a horizontal page may bulge at the base of the unturned portion as the spine rotates. Next, the page turning device 140 equipped with a scan object smoothing portion will be described.

[0062] Page turning device

[0063] refer to Figure 3 , which shows an example of a page turning device 140 equipped with a scan object smoothing unit 200 according to an embodiment of the present disclosure, wherein reference numeral 1001 indicates a motion trajectory of the page turning device 140 during a page turning operation. The page turning device 140 may be, for example, a reference Figure 2 The page turning device 140 performs a page turning operation to separate the first scan object (current page) from the second scan object (next page). In other words, the page turning device 140 performs a page turning operation to separate the first scan object from the second scan object.

[0064] In this case, the page turning device 140 according to an embodiment of the present disclosure may include a page bending adsorption structure 1301 and a non-bending page adsorption structure 1302 as examples of a force applying device (such as a suction cup), a page bending adsorption structure supporting device 1403 as an example of a force applying device mounting part, and a scanning object smoothing part 200.

[0065] In the embodiment of the present disclosure, the force applying device may be, for example, a suction cup configured to apply force to the scanned object. In this case, the page turning device 140 may absorb the top sheet of paper via the suction cup and separate the first scanned object (current page) from the second scanned object (next page) through a subsequent page turning operation.

[0066] The force applying device mounting portion may be, for example, a reference Figure 2 The page bending adsorption structure supporting device 1403. In this case, the force applying device is provided at the force applying device mounting portion, and as Figure 2 As shown in FIG, the force applying device mounting portion can move along a track 1001 set at a predetermined angle (eg, 45°) relative to the XY plane, thereby driving the force applying device to move.

[0067] In an embodiment of the present disclosure, the scanned object smoothing portion 200 may be provided at the force applying device mounting portion, and the scanned object smoothing portion 200 is configured so that when the force applying device mounting portion brings the force applying device close to the scanned object, the scanned object smoothing portion contacts the scanned object before the force applying device.

[0068] The term “the scanned object smoothing portion may be provided on the force applying device mounting portion” may mean that the scanned object smoothing portion is fixed to the force applying device mounting portion or that the scanned object smoothing portion is connected to the force applying device mounting portion via an intermediate structure.

[0069] In the embodiment of the present disclosure, when the force applying device mounting portion brings the force applying device close to the scanned object (for example, along the Figure 3 The scanning object smoothing portion is lower than the force applying device in the Z-axis direction (vertical direction). Figure 3 As shown, the scan object smoothing portion 200 is set to be lower than the force applying device H, so that when the page turning device 140 moves downward along the track 1001, the scan object smoothing portion 200 contacts the scan object 180 before the force applying device.

[0070] Specifically, since the force applying device mounting portion moves along the predetermined track 1001 in the XZ plane (first plane), it can slide on the scanning object during the period from when the scanning object smoothing portion 200 contacts the scanning object to when the force applying device contacts the scanning object, thereby eliminating wrinkles, bulges, etc. on the scanning object.

[0071] In the embodiment of the present disclosure, the scanning object smoothing portion may be, for example, an elastic component. Specifically, the scanning object smoothing portion may be a spring sheet, a metal sheet, and the like.

[0072] In the embodiment of the present disclosure, one end of the elastic member is fixed to the mounting portion of the force applying device (fixed end), and the other end is not constrained (free end), and is arranged in an arc shape in the XZ plane. That is, the elastic member is arranged along the X direction, thereby preventing the elastic member from causing damage to the scanned object due to the difference between the moving direction and the force applying direction during the smoothing operation.

[0073] According to a specific implementation of the embodiment of the present disclosure, multiple scanning object smoothing parts can be set along the Y-axis direction, and each scanning object smoothing part is set in the XZ plane, so that the smoothing effect can be further improved by the multiple scanning object smoothing parts.

[0074] In this case, the projection lengths of the plurality of scanning object smoothing portions in the X direction may be the same. However, it is particularly meaningful to configure the projection lengths of the plurality of scanning object smoothing portions in the X direction to be different, because the scanning device 100 may need to scan books of different sizes (for example, A4 and A5). When the page turning operation starts, the spine position of the A5 paper book is closer to the center than the spine position of the A4 paper book. Figure 2 In this case, if the smoothing portion for A4 paper is used to smooth A5 paper, the free end of the smoothing portion may contact the flipped paper, which is not conducive to smoothing the paper. In this case, the projection of the smoothing portion for A5 paper in the X direction should be shorter than that of the smoothing portion for A4 paper.

[0075] Furthermore, to adapt the object smoothing section to paper sizes of varying sizes, the multiple object smoothing sections can also have different projected lengths in the vertical direction (Z-axis direction). In other words, the multiple object smoothing sections can be positioned at different heights. Thus, for larger (e.g., A4) paper, the lower object smoothing section can be used for smoothing, while for smaller (e.g., A5) paper, the higher object smoothing section can be used for smoothing.

[0076] See also Figure 4 , which shows a schematic diagram of a page turning device 140 according to another embodiment of the present disclosure. In the above description, the scanned object smoothing unit 200 is fixedly mounted on the force applying device mounting portion. Unlike this, in the present embodiment, the page turning device 140 may further include a drive device 2001, which is used to drive the scanned object smoothing unit 200 to rotate within the XZ plane. In other words, the scanned object smoothing unit can rotate about the Y axis. It should be understood that in the present embodiment, the scanned object smoothing unit 200 may also rotate at a certain angle (e.g., in the range of 0 to 30°) relative to the XZ plane.

[0077] Specifically, if Figure 4 As shown, the driving device 2001 may be directly connected to the scanning object smoothing portion 200 to drive the scanning object smoothing portion 200. Alternatively, the driving device 2001 may be connected to the scanning object smoothing portion 200 via a transmission mechanism 2002.

[0078] It should be noted that the driving device 2001 may be, for example, a separate driving motor, but it should be understood that the driving device 2001 may also be a motor for page turning or paging. Figure 4In the example shown, the driving device 2001 is also used to drive the paging device 140 so that before starting to perform the page turning operation, the force applying device moves along a trajectory such as 2003 to separate the first scanning object and the second scanning object by an angle.

[0079] In the case where the driving motor 2001 for driving the scanning object smoothing part 200 is installed, when the force applying device installation part drives the force applying device to approach the scanning object (for example, along the Figure 4 The track 1001 in FIG. 1 moves downward), the scanning object smoothing portion 200 is lower than the force applying device in the Z-axis direction (vertical direction). Specifically, as Figure 4 As shown, the scan object smoothing portion 200 is set to be lower than the force applying device H, so that when the page turning device 140 moves downward along the track 1001, the scan object smoothing portion 200 contacts the scan object 180 before the force applying device.

[0080] After the force applying device installed on the force applying device mounting portion contacts the scanning object and before it starts to move along the predetermined trajectory 1001 to separate the first scanning object from the second scanning object, in order to prevent the scanning object smoothing portion 200 that contacts the scanning object when the force applying device mounting portion approaches the scanning object from affecting the separation operation of the first scanning object from the second scanning object, the scanning object smoothing portion 200 can be driven in advance by the driving device 2001 to separate the scanning object from the scanning object.

[0081] Furthermore, in the disclosed embodiment, the paging device 130 can perform a separate paging operation, which is used to separate the first scanned object from the second scanned object by a certain angle before performing the page turning operation, and then the page turning operation is performed by the paging device. Specifically, before performing the page turning operation, the paging motor (e.g., 2001) can drive the paging device to move along a predetermined trajectory to separate the first scanned object from the second scanned object by a certain angle. In this case, the driving device 2001 drives the scanned object smoothing unit 200 to separate from the scanned object before the paging device 130 performs the paging operation.

[0082] According to a specific implementation of the embodiment of the present disclosure, a flexible material may be provided on the outer surface of the smoothing portion of the scanned object. The flexible material may be, for example, rubber, sponge, cloth, and the like.

[0083] Specifically, a flexible material layer (not shown) is disposed on the outer surface of the object smoothing portion 200. This flexible material layer protects the pages while smoothing them, while also improving the smoothing effect. While wrapping the object smoothing portion 202 with the flexible material layer is preferred, removing the flexible material layer is also within the scope of this disclosure.

[0084] According to one embodiment, the flexible material layer is a rubber layer. The function of the flexible material layer is to protect the pages of the book when smoothing them, and to achieve a better smoothing effect. Obviously, the flexible material layer is not limited to a rubber layer, and other types of flexible materials may also be used, such as a sponge layer or a cloth layer, which can also achieve the same above-mentioned effects.

[0085] In another preferred embodiment, the transmission mechanism 2002 may be a rigid linkage mechanism, with an active end of the rigid linkage mechanism connected to the drive motor 2001 and a driven end connected to the scanned object smoothing unit 200. Driven by the rigid linkage mechanism, the scanned object smoothing unit 200 is configured to contact and smooth the scanned object 180 before the force applying device mounting portion brings the force applying device into contact with the scanned object 180, and to separate from the scanned object 180 before the force applying device mounting portion brings the force applying device out of contact with the scanned object 180.

[0086] In addition, the scanning device according to the present disclosure further includes a controller and a control output device. The control output device can be any mechanical structure, such as a manipulator, a robotic arm, or a connecting rod, as long as it can transmit control operations to the object smoothing unit 200. The controller includes a central processing unit (CPU) serving as a control unit. Specifically, the control output device is connected to the object smoothing unit 200. A control program is programmed in the controller through software to control the object smoothing unit 200 to cooperate with the page turning device 140, ensuring that the object smoothing unit 200 contacts and smoothes the object before the force applying device mounting portion and the force applying device contact the object 180.
