Next, referring to fig. 2, the various components of the scanning apparatus 100 according to the present disclosure are described in connection with a scanning process. In fig. 2, the same reference numerals as in fig. 1 denote the same components, and when a component is constituted by a plurality of portions, the reference numerals in fig. 1 are used with suffix 1, 2, 3, etc. added thereto, to denote the respective portions constituting the component, and, for example, reference numerals 1301, 1302 … 1305 denote the respective portions of the sorting device 130. And when a single part, such as 1303, is made up of multiple components, each component is identified with the last three digits of the reference number of that part, plus a suffix numeral, such as 3031 and 3032. The above-described naming convention for reference numerals also applies to subsequent figures.

It should be noted that in the following description, the term "scan object" refers to a carrier on which information can be recorded. Information recorded on a scan object is converted into digital information by a scanning operation of a scanning device. The scan object includes, for example, plain paper, coated paper, plastic sheet, and the like. Further, although in the following description, the present disclosure is described with an example in which a sheet of a book is a scanning target, the scanning target may be, for example, a newspaper, a photograph, and may also be a leaflet material, a stapler bound material, a magazine, or the like.

Further, in the following description, a length direction of the supporting device 110 of the scanning device 100 is defined as an X direction, a direction perpendicular to a plane in which the supporting device 110 is located is defined as a Z direction (not shown), and a direction perpendicular to an XZ plane is defined as a Y direction.

As shown in fig. 2, the scanning apparatus 100 according to the present disclosure includes a supporting device 110, and the supporting device 110 is disposed on a gantry in a fixed and/or movable manner. A book 201 as a scanning object is supported on the supporting device 110. To facilitate subsequent scanning operations, one side of book 2011 (e.g., the spine) may be secured to support device 110 by holding device 120. The holding device 120 is, for example, a holding device that fixes the book 2011 to the surface of the supporting device 110 by, for example, holding the spine of the book 2011.

As shown in fig. 2, the page turning device 140 according to the present disclosure includes a leading structure moving device 1401, a position adjusting device 1402, and a sheet bending suction structure supporting device 1403.

Further, the sorting device 130 according to the present disclosure includes a paper bending suction structure 1301, a non-bending paper suction structure 1302, an air blowing and sheet pressing device 1303, a suction force generating device 1304, and a duct 1305. Wherein the wind blowing paging device 1303 includes a wind generating device 3031 and a wind blowing port 3032. The non-bendable paper suction structure 1302 is a suction structure designed for paper having a large hardness, and for convenience of description, the paper bending suction structure 1301 and the non-bendable paper suction structure 1302 are collectively referred to as a suction structure hereinafter.

As shown in the figure, a paper bending suction structure 1301 and a non-bendable paper suction structure 1302 are provided integrally, and are connected to a leading structure moving device 1401 through a paper bending suction structure support device 1403. Specifically, the suction structures 1301 and 1302 are fixed to the paper bending suction structure support device 1403, the paper bending suction structure support device 1403 is movable along a slide rail provided on the leading structure moving device 1401, the slide rail is set at a predetermined angle with respect to the XY plane, and when the paper bending suction structure support device 1403 moves along the slide rail, the leading suction structures 1301 and 1302 move in the direction of the slide rail. Further, the position of the entire leading structure moving device 1401 in the Z direction can be adjusted by the position adjusting device 1402, thereby adjusting the initial positions of the suction structures 1301 and 1302 in the Z direction.

In addition, for example, the suction force of the negative pressure generated by the suction force generating device 1304 of the separation device 130 is transmitted to the suction structures 1301 and 1302 via the duct 1305, and suction portions are provided on the suction structures 1301 and 1302, and when the suction portions come into contact with the paper, the suction force is generated to the paper.

Specifically, once the book 2011 is moved to the scanning start position along with the supporting device 110, the suction structures 1301 and 1302 move downward along the slide rails on the leading structure moving device 1401 as the paper bends the suction structure supporting device 1403, and when the book is moved to the position of contact with the uppermost paper of the book 2011, the suction force generating device 1304 generates negative pressure suction force, and transmits the negative pressure suction force to the suction portions provided on the suction structures 1301 and 1302 via the pipe 1305, and sucks the uppermost paper by the suction portions.

Once sucked, the sheet bending suction structure support device 1403 moves upward along the slide rail on the drive structure movement device 1401, thereby separating the uppermost sheet from the subsequent sheet by an angle, and when the separated angle reaches a predetermined value, the back surface of the uppermost sheet and the front surface of the subsequent sheet are imaged by the cameras 1501 and 1502 provided, and the captured image is converted into digital information by subsequent processing. In this process, in order to better separate the uppermost paper from the subsequent paper, wind power may be generated by the wind power generating device 3031 of the blowing and pressing device 1303, and the subsequent paper may be pressed by blowing through the blowing port 3032 of the blowing and pressing device 1303, so as to achieve better separation. In the present disclosure, the air blowing paging device 1303 is an example of an auxiliary paging device. It should be noted that although the air-blowing flapper device 1303 is fixedly disposed in the vertical direction in the present exemplary embodiment, the present invention is not limited thereto. For example, the blowing paging device 1303 may be fixedly disposed in a horizontal direction to assist paging by blowing at an initial stage of paging. That is, the auxiliary paging device may not move during paging. Alternatively, the auxiliary sorting device may be mounted on the same component together with the suction portion to perform the sorting work, thereby being capable of providing the auxiliary sorting effect throughout the sorting process.

At the same time as or after the image forming operation, the turned sheets are pressed by the kickback prevention devices 1601 and 1602 provided on both sides of the book 2011 to be prevented from being kicked back, facilitating the next turning of the pages. Specifically, the kickback prevention apparatus 1601 includes a rotation device 6012 and a rotation device position adjustment device 6011, the kickback prevention apparatus 1602 includes a rotation device 6022 and a rotation device position adjustment device 6021, the rotation device 6012/6022 is provided in a "Z" shape, one end thereof is fixed to the rotation device position adjustment device 6011/6021, and the height of the position is adjustable, and the other end thereof can press the turned sheet of paper by rotation of the rotation device 6012/6022, thereby preventing the kickback thereof. Thus, the page turning and image forming operations of the single sheet are completed.

By repeating the above operation processes, continuous page turning and imaging operations of the book 2011 can be realized.

In the above description, although the present disclosure has been described in terms of the specific forms of the supporting device 110, the holding device 120, the paging device 130, the page turning device 140, the image forming device 150, and the kickback prevention device 160, the present disclosure is not limited thereto, but may take various other forms as long as the forms taken can fulfill the functions of the respective components.

For example, although the adsorption force generating device 1304 has been described by taking a vacuum adsorption device as an example, the adsorption force generating device 1304 is not limited thereto, but may include, for example, one or more of a vacuum force generating device, an electrostatic adsorption force generating device, a magnetic adsorption force generating device, an adhesion force generating device, a biomimetic adsorption force generating device, and a nano-stick. The force generated is not limited to the suction force, and may be a pushing force applied to the paper. That is, in the present disclosure, the suction force generating device 1304 is an example of a force generating device configured to generate a force exerted on a scanning object.

Further, the apparatus for assisting the sorting is not limited to the air blowing paging apparatus 1303, but a mechanical paging apparatus, a negative pressure paging apparatus, and the like may be employed as long as they can achieve the effect of assisting the sorting.

The various forms that the supporting device 110, the holding device 120, the paging device 130, the page turning device 140, the imaging device 150, and the kickback prevention device 160 according to the present disclosure may take and their arrangements are specifically described in patent CN 201721385718.2, which is incorporated herein by reference in its entirety.

During the scanning process of the scanning device 100, the top sheet and the next sheet need to be separated to realize the page-by-page scanning. However, since the sheet has a certain air permeability, in the scanner device 100 for separating the sheets by vacuum suction, during suction of the uppermost sheet, the latter sheet may generate a local vacuum region around the suction position due to the air permeability of the sheet. The atmosphere on both sides of the two sheets can apply pressure to the local vacuum area, so that the phenomenon that the latter sheet is jointly adsorbed in the process of adsorbing the uppermost sheet is caused, and the sheets cannot be effectively separated. The term "air permeability" as used herein refers to the average air flow per unit area of paper, expressed in microns/(pascal-seconds), under specified conditions, per unit time and unit pressure differential.

Further, in the configuration of separating the sheets by the vacuum suction device, in order to make the suction force of the sheets sufficient, a plurality of suction cups are generally provided to suck the sheets, and the plurality of suction cups may be arranged in a row, for example. In the process of adsorbing the paper, not all the suction cups are in contact with the paper, so that a phenomenon that part of the suction cups are sucked in an empty state is caused, and large noise is generated. For example, in the case where a plurality of suction cups are provided with a width larger than that of the sheet, opening the suction cups all over causes the suction cups to partially open, resulting in generation of large noise. Therefore, in the present exemplary embodiment, the switching of the plurality of suction cups, that is, the suction force exerted on the sheet by the suction cups, is controllable.

In the present exemplary embodiment, the uppermost sheet and the following sheet are effectively separated by providing a special sorting device 130 to perform a sorting operation, as opposed to directly separating the uppermost sheet and the following sheet by a page turning operation, and in the present exemplary embodiment, the term "separated" means at least partially in a non-fitted state.

Next, the paging device 130 according to the present exemplary embodiment is described with reference to the drawings. In the following description, the suction force generating device 1304 and the duct 1305 included in the paging device 130 may be the same as those described above with reference to fig. 2, and the following description focuses mainly on the page bending suction structure 1301.

Fig. 3 and 4 show views of the page bending suction structure 1301 according to the present exemplary embodiment, in which fig. 3 shows a structural schematic view of the page bending suction structure 1301 viewed from the upper side, and fig. 4 shows a structural schematic view of the page bending suction structure 1301 viewed from the lower side. Wherein the lower side refers to a side in contact with the paper, and the upper side is an opposite side of the lower side.

As shown in fig. 3, the page bending suction structure 1301 according to the present exemplary embodiment includes a suction cup mounting portion 3011, a first slide rail 3012, a side wall 3013, a stopper portion 3014, a spring mounting bar 3015, a pressing plate 3016, a cushion 3017, a second slide rail 3018, a suction cup mounting nut 3019, a limit switch 3020, and a pulling portion 3021. Further, as shown in fig. 4, the page bending suction structure 1301 according to the present exemplary embodiment further includes a suction cup 3022, a contact determination switch 3023, and a stopper portion mounting portion 3024.

The suction pad mounting portion 3011 mounts a suction pad 3022, and the suction pad 3022 applies suction force to the sheet. In the suction process, the suction cup mounting portion 3011 and the lower surface of the pressing plate 3016 may be in the same plane to be in planar contact with the sheet at the initial suction position. Specifically, in the sorting process, the longitudinal direction of the suction cup mounting portion 3011 and the pressing plate 3016 coincides with the longitudinal direction of the sheet (the clamping direction of the sheet), and when the pressing plate 3016 of the page bending suction structure 1301 comes into contact with the sheet, the contact determination switch 3023 provided on the pressing plate 3016 is touched, thereby determining that the current position is the position where the page bending suction structure 1301 comes into contact with the sheet, and setting the current position as the suction initial position.

Here, it is not necessary that both the pressure plate 3016 and the suction cup mounting portion 3011 press the surface of the sheet, and it is sufficient that only the lower surface of the suction cup mounting portion 3011 presses the surface of the sheet. However, it is preferable that the pressing plate 3016 and the suction cup mounting portion 3011 press the surface of the sheet.

A suction cup 3022 or other suction structure is provided on the lower surface of the suction cup mounting portion 3011 to suction a sheet at an initial suction position by, for example, a suction force generated by the suction force generating apparatus 1304. In the present exemplary embodiment, the suction cup 3022 is taken as an example of the force applying device configured to apply the suction force generated by the suction force generation apparatus 1304 to the sheet. Further, the suction cup mounting portion 3011 may be provided with a groove or the like to reduce the weight of the entire page bending suction structure 1301.

The suction cup attachment portion 3011 may be made of a lightweight material such as resin or aluminum alloy, and is preferably capable of withstanding a bending moment. The suction cup 3022 may be, for example, a rubber suction cup, a sponge suction cup, an antistatic suction cup, or the like, and may be a dedicated suction cup (such as a muslim vacuum suction cup PAG-8) that adsorbs a sheet of paper. The suction cup 3022 can be attached to the suction cup attachment portion 3011 by a suction cup attachment nut 3019, for example.

The pressing plate 3016 may be configured to press the sheet before or during the sorting operation to prevent the sheet from being wrinkled or the like. The pressing plate 3016 is connected to the suction pad mounting portion 3011 via a side wall 3013. Specifically, in the present exemplary embodiment, a first slide rail 3012 and a second slide rail 3018 are provided on the side wall 3013, and two slide bearings (sliding portions) are provided at each longitudinal end portion of the suction cup mounting portion 3011, which are respectively mounted in the first slide rail 3012 and the second slide rail 3018, so that the suction cup mounting portion 3011 can move relative to the pressure plate 3016 along a trajectory defined by the first slide rail 3012 and the second slide rail 3018.

Further, in order to enable the suction cup mounting portion 3011 to be reset for the next sorting operation after the current sorting operation is completed, the page bending suction structure 1301 according to the present exemplary embodiment includes a spring mounting rod 3015, one end of the spring mounting rod 3015 is hinged to the suction cup mounting portion 3011, and the other end is mounted in a hole in the stopper portion 3014 via a slide bearing, and the stopper portion 3014 is hinged to the stopper portion mounting portion 3024, and the stopper portion mounting portion 3024 is fixedly connected to the pressure plate 3016. In addition, a spring, not shown, is mounted on the spring mounting bar 3015, and thus, the spring is compressed during movement of the suction cup mounting portion 3011 relative to the pressure plate 3016 along a trajectory defined by the first slide rail 3012 and the second slide rail 3018. After the sorting operation is finished, the suction cup mounting portion 3011 is reset by the resilient force of the spring.

In the present exemplary embodiment, the movement of the suction pad mounting portion 3011 with respect to the pressure plate 3016 is realized by pulling a pulling portion 3021 provided on the suction pad mounting portion 3011 with a pulling rope or the like. The pulling action may be achieved by a motor or the like, for example.

In order to limit the limit position of the movement during the movement of the suction pad mounting portion 3011, the movement may be controlled by a limit switch 3020 provided on the suction pad mounting portion 3011. Specifically, for example, a photoelectric switch is provided on the pressing plate 3016, and when the limit switch 3020 on the suction cup mounting portion 3011 moves to a specific position along with the suction cup mounting portion 3011, the photoelectric switch is turned off, so that the motor that pulls the suction cup mounting portion 3011 stops the pulling operation. On the other hand, the pressing plate 3016 according to the present exemplary embodiment is further provided with a cushion 3017, and when the suction cup mounting portion 3011 moves to a position in contact with the cushion 3017, the movement of the suction cup mounting portion 3011 with respect to the pressing plate 3016 is stopped by means of physical stop.

In this case, as shown in fig. 3, since both ends of the spring-mounting lever are in the hinge state, a large elastic force is required from the spring to return the spring when the next paging operation is performed.

For this, as shown in fig. 5, in the embodiment of the present disclosure, the structure of the spring mounting bar 3015 and the spring mounted on the spring mounting bar 3015 as described above is improved, and the spring assembly of the present disclosure includes a guide bar 300 and a spring mounted on the guide bar 300.

Specifically, the fixing portion 3016 further includes a stopper portion 3014 fixedly connected to the side wall 3013. The spring assembly includes a guide bar 300 and a spring, not shown, mounted on the guide bar 300; one end of the guide rod 300 is hinged to the force applying device mounting portion 3011, and the other end passes through a hole formed in the stopper portion 3014, so that the spring is compressed when the force applying device mounting portion 3011 moves along a track defined by the slide rail. And after the page separation operation is completed, since one end of the compressed spring close to the stopper 3014 is in contact with the stopper 3014 and the other end is in contact with the suction cup mounting portion 3011, when the motor stops the pulling action, the spring will make the suction cup mounting portion 3011 move along the track 3012 due to the resilience force. In comparison with the case shown in fig. 3, since both ends of the guide bar 300 are not all hinged and one end of the spring near the stopper 3014 corresponds to a fixed connection, it is advantageous for the spring to return.

The above describes the case where one end of the guide rod 300 passes through the hole in the stopper 3014, the stopper 3014 is provided to the fixing portion 3016, and the other end of the guide rod 300 is hinged to the suction cup mounting portion 3011. However, the embodiments of the present disclosure are not limited thereto, but may be configured as follows: the suction cup mounting portion 3014 is provided on the suction cup mounting portion 3011, the stopper portion 3014 is fixedly connected to the suction cup mounting portion 3011, one end of the guide rod 300 passes through a hole provided on the stopper portion 3014, and the other end is hinged to the fixing portion 3016.

In the embodiment of the present disclosure, the diameter of the hole formed in the stop portion 3014 is larger than the diameter of the guide rod 300, so that the guide rod 300 and the hole formed in the stop portion 3014 can be prevented from interfering with each other and interfering with the separation process during the movement of the suction cup mounting portion 3011 along the predetermined track.

According to a preferred embodiment, the spring is preferably a cylindrical spring.

In addition, to provide a sustained return force, the spring is required to be in a compressed state at all times. That is, even when the suction cup attachment portion 3011 is in a horizontal state, the spring is required to be always in a compressed state so as to secure the horizontal state of the suction cup attachment portion 3011.

It should be noted that in the above description, the example in which the suction cup mounting portion 3011 is taken as the force applying device mounting portion, the example in which the suction cup 3022 is taken as the force applying device, and the example in which the pressure plate 3016 is taken as the fixing portion have been described, but the forms of these components are not limited thereto, and may take other forms as long as they satisfy the functions described in the present disclosure.

Second embodiment

Hereinafter, a second embodiment according to the present disclosure is described, and in the following description, description is given mainly focusing on differences from the first embodiment, and parts not specifically described may be the same as those in the first embodiment, in order to avoid unnecessarily obscuring the present disclosure.

In the second embodiment according to the present disclosure, the paging device 130 further includes a margin determination device. The margin distance determining apparatus is mainly used to determine the distance of the suction cup 3022 from the edge of the sheet, specifically, the distance of the suction cup 3022 from the edge of the end of the sheet opposite to the nip end.

Specifically, in the present exemplary embodiment, the margin determining device may be configured by a luminance sensor. For example, a brightness sensor may be mounted on the lower surface of the suction cup mounting portion 3011 with a fixed distance from the center position of the suction cup. In the suction operation, the lower surface of the suction cup mounting portion 3011 is first moved in the X direction without contacting the sheet, and for example, when the change in brightness detected by the brightness sensor is larger than a predetermined value, it is determined that the position where the brightness sensor is located has reached the edge of the sheet, and the suction cup position is further moved to a predetermined position by motor control or the like.

In one embodiment, the suction cup mounting portion 3011 may not be movable in the X direction, but the position of the suction cup 3022 on the suction cup mounting portion 3011 may be movable. In this manner, the position of the suction cup 3022 on the sheet can be adjusted by merely adjusting the position of the suction cup 3022 on the suction cup mounting portion 3011.

Although in the above description, the brightness sensor is described as an example of the margin determination device, other sensors or devices are possible as long as they can determine the distance of the suction cup 3022 with respect to the sheet edge.

Third embodiment

Hereinafter, a third embodiment according to the present disclosure is described, and in the following description, description is given mainly focusing on differences from the first and second embodiments, and parts not specifically described may be the same as those in the first and second embodiments, in order to avoid unnecessarily obscuring the present disclosure.

In the above description, the separation operation of the sheet has been described taking the suction of the sheet by the suction cup 3022 as an example, but other suction methods such as electrostatic suction, magnetic suction, bionic suction, and the like may be employed as long as the suction positions of these suction methods and the movement method of the suction cup mounting portion can satisfy the above description with reference to the first and second embodiments.

In the present exemplary embodiment, a nano-stick (also referred to as a sticky note or a removable glue) is used instead of the vacuum chuck to adhere the paper. In the case of using the nano-adhesive, the nano-adhesive is both the adsorption force generating apparatus and the force applying device.

The paper paging operation through the nanometer sticking tool has the advantages of high success rate and low noise. However, since the paper structure is fibrous, fine fibers falling off from the paper may adhere to the surface of the nano-sized binder after a plurality of times of adsorption, resulting in insufficient adhesion, and the paging effect is significantly deteriorated after about 10 paging operations through experimental tests. Therefore, a cleaning device can be arranged for the nanometer sticky tool, and the nanometer sticky tool can be used again after being cleaned and dried by clear water. The paging device designed in this way has high paging success rate, and the noise can be kept between 45dB and 55 dB.

Furthermore, in addition to providing a cleaning device for the nano-adhesive, a cleaning device may also be provided for other types of force-generating devices according to the invention.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
