Description

Paging device and scanning device with page detection function

Technical Field

The disclosure relates to the field of scanning technologies, and in particular relates to a paging device and a scanning device with a page detection function.

Background

During scanning, the scanning apparatus performs suction, page turning, and imaging actions on a scanned object to convert pictures, characters, etc. on the scanned object into electronic data. In the scanning process, the scanned objects need to be turned page by page to realize imaging of the scanned objects of each page. If a double page or even a plurality of pages are turned over at a time during the page turning process, the electronic data of the scanned object is lost. It is therefore necessary to measure whether the scanning object is a single page or multiple pages in the scanning process, and in the case of multiple pages, it is necessary to take additional action so that the multiple pages are separated.

For the measurement of whether the scanning object is a single page or a plurality of pages, ultrasonic detection is the mature technology at present, and other technologies are expensive or not mature. The principle of ultrasonic detection is as follows: the ultrasonic wave is transmitted to a scanning object, the ultrasonic wave receiving end can receive the ultrasonic wave information, if the scanning object is a single scanning object, the ultrasonic wave information is weaker than the condition without shielding, if the scanning object is two or more scanning objects, the signal received by the ultrasonic wave receiving end is weaker, and therefore whether the scanning object is a single page or multiple pages can be judged.

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 the book 201 (e.g., the spine) may be secured to the support device 110 by the holding device 120. The holding device 110 is, for example, a clamping device that fixes the book 201 to the surface of the supporting device 110 by, for example, clamping the spine of the book 201.

As shown in FIG. 2, the page turning apparatus 140 according to the present disclosure includes a leading structure movement device 1401, a position adjustment device 1402, and a page bending suction structure support device 1403.

Further, the paging device 130 according to the present disclosure includes a sheet bending suction structure 1301, a non-bending sheet 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 sheet suction structure 1302 is a suction structure designed for a paper sheet having a large hardness, and for convenience of description, the sheet bending suction structure 1301 and the non-bendable sheet suction structure 1302 are collectively referred to as a suction structure hereinafter.

As shown, a page bending suction structure 1301 and a non-bendable page suction structure 1302 are provided as one body, and are connected to the leading structure moving device 1401 through a page bending suction structure support device 1403. Specifically, the suction structures 1301 and 1302 are fixed to the page bending suction structure support device 1403, the page bending suction structure support device 1403 is capable of moving 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 page 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 cups are provided on the suction structures 1301 and 1302 to generate suction force to the paper when the suction cups are brought into contact with the paper.

Specifically, once the book 201 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 along with the page bending suction structure supporting device 1403, and when moving to a position where it contacts the uppermost sheet of the book 201, the suction force generating device 1304 generates a negative pressure suction force, and transmits it to the suction cups provided on the suction structures 1301 and 1302 via the duct 1305, and sucks the uppermost sheet by the suction cups.

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 sheet from the subsequent sheet, wind power may be generated by the wind power generating device 3031 of the blowing and pressing device 1303, and the subsequent sheet may be pressed by blowing air through the blowing port 515 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 page-pressing 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.

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 at both sides of the book 201 to be prevented from being kicked back, facilitating the next page turning. 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, the continuous page turning and imaging operations of the book 201 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 and arrangements that the support 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 are specifically described in applicant's own patent CN 201721385718.2, the entire contents of which are incorporated herein by reference.

Further, although in the above description, the paging device is described as including the non-bendable sheet adsorption structure 1302 and the air blowing and sheet pressing apparatus 1303, these components may be omitted without affecting the overall function of the scanning device 100.

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.

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 the 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.

As described above, during scanning, pages of a scanned object need to be turned page by page to realize imaging of the scanned object per page. If a double page or even a plurality of pages are turned over at a time during the page turning process, the electronic data of the scanned object is lost.

Therefore, the embodiment of the present disclosure provides a paging device 130 with a page detection function, where the paging device 130 is configured to enable the first scan object and the second scan object to be at least partially in a non-bonded state. It can also be said that the paging device 130 is used to separate two adjacent scan objects, thereby achieving the purpose of paging page by page. However, if the first scan object is sucked by the suction cup due to air leakage of the scan object, etc., the first scan object and the second scan object may not be separated normally, and a case where two or more pages are opened at a time may occur.

Therefore, in the embodiment of the disclosure, the paging device 130 includes a force generating device 1304, and the generating device 1304 is, for example, one or more of a vacuum force generating device, an electrostatic attraction force generating device, a magnetic attraction force generating device, an adhesion force generating device, a bionic attraction force generating device, and a nano-adhesive.

In addition, the paging device 130 further includes an adsorption mechanism 1301, the adsorption mechanism 1301 is capable of approaching or separating from the scan object 201 along a predetermined trajectory, and a force applying device 3022 is mounted to the adsorption mechanism 1301, and the force applying device 3022 is configured to apply a force generated by the force generating apparatus (1304) to the scan object 201. Specifically, for example, the suction mechanism 1301 is fixed to the page bending suction structure support device 1403, and the page bending suction structure support device 1403 can move along a slide rail provided on the leading structure moving device 1401 to approach or separate from the scanning object 201.

In addition, referring to fig. 5 and 6, the paging device 130 according to the embodiment of the present disclosure further includes a detection apparatus, wherein fig. 5 and 6 show a split type detection apparatus, and in fig. 5 and 6, 3025 is an ultrasonic wave transmitting device fixing means for fixing an ultrasonic wave transmitting device, 3026 is an ultrasonic wave transmitting device, 3027 is a filter hole, 3028 is an ultrasonic wave receiving device fixing means for fixing an ultrasonic wave receiving device, and 3029 is an ultrasonic wave receiving device. The detection device may be provided to the suction mechanism 1301, for example, and may transmit a signal to a first scan object that has undergone a sorting operation while being at least partially in a non-attached state at the start of page turning to determine whether the first scan object is a single page or a plurality of pages. It should be understood that although fig. 5 and 6 show a separate type of detection apparatus, the detection apparatus may be of an integrated type, i.e., the ultrasonic wave emitting device 3025 and the ultrasonic wave receiving device 3028 are both mounted on the suction mechanism 1301. In addition, it should also be understood that the positions of the ultrasound emitting device and the ultrasound receiving device 3029 may be interchanged 3026 without affecting the operational state of the entire device.

Specifically, for example, the inspection apparatus may be an ultrasonic inspection apparatus, and after the paging operation is performed, ultrasonic waves are emitted to the scanning target that has undergone paging, and whether the scanning target is a single page or a plurality of pages is determined from the received ultrasonic signals.

In the embodiment of the present disclosure, in order to enable the detection apparatus to accurately detect a single or double page or the like of a scanned object, the emitted signal needs to be limited within a predetermined range. Specifically, in the embodiment of the present disclosure, the signal is emitted to a predetermined range of the first scanning object, and the predetermined range is a range in which a distance from an edge of the first scanning object is less than a predetermined value. That is, the emitted signal needs to be close to the edge of the scanned object because during the page turning process, the edge positions of the scanned object are separated first and are not substantially attached together again once separated, while if the middle position of the scanned object is detected, it may need to be detected at an intermediate stage of the page turning process. However, in this case, once the presence of two or more pages is detected, more steps are required or the formation is performed with a longer motion to perform paging again. Therefore, in the disclosed embodiments, the emitted signal needs to be confined to a predetermined range of the scanned object.

According to a specific implementation manner of the embodiment of the present disclosure, the detection device is an ultrasonic device, and the ultrasonic device includes an ultrasonic wave transmitting device and an ultrasonic wave receiving device.

Further, the ultrasonic wave transmitting device and the ultrasonic wave receiving device may be provided separately. Specifically, one of the ultrasonic wave transmitting device and the ultrasonic wave receiving device is fixed to the adsorption structure 1301, and the position of the other is fixed. Specifically, one of the ultrasonic wave emitting device and the ultrasonic wave receiving device may be fixed to the pressing plate 3016 side of the suction structure 1301, so that the ultrasonic wave emitting device or the ultrasonic wave receiving device fixed to the pressing plate 3016 side can emit or receive the ultrasonic wave after the suction plate mounting portion 3011 drives the scanning object to move to a specific position without moving along with the suction plate mounting portion 3011 in the paging process.

Alternatively, the ultrasonic wave transmitting device and the ultrasonic wave receiving device may be provided integrally. Specifically, both the ultrasonic wave emitting device and the ultrasonic wave receiving device are fixed to the suction structure 1301, specifically, to the fixing portion side of the suction structure 1301, that is, the pressing plate 3016 side, so that the detection of the number of pages to be scanned can be performed throughout the page turning process.

According to a specific implementation manner of the embodiment of the present disclosure, in order to be able to distinguish whether the scan target is a single page or multiple pages, the paging device 130 further includes a memory, and the memory stores the following data: an ultrasonic signal received by the ultrasonic wave receiving means when ultrasonic waves are transmitted to the scanning object of a single page or a plurality of pages.

In this manner, when the degree of similarity between the signal detected by the detection device and the signal stored in the memory is greater than a predetermined value, it can be determined that the scan target is a scan target of the corresponding number of pages.

According to a specific implementation manner of the embodiment of the disclosure, in addition to comparing the signal detected by the detection device with the signal stored in the memory, the detection device further sends a signal indicating the number of pages of the scanned object, wherein the signal indicating the number of pages of the scanned object comprises a signal indicating a single page and a signal indicating a non-single page. That is, after comparison with the signal stored in the memory, a conclusion is made as to whether the scanning object is a single page or a plurality of pages based on the comparison, and a signal indicating the number of pages is also directly transmitted. Thus, the judgment can be more conveniently carried out.

According to a specific implementation manner of the embodiment of the present disclosure, the paging device further includes an ultrasonic wave filtering device configured to block an ultrasonic wave having a divergence angle larger than a predetermined threshold value, and disposed between the ultrasonic wave transmitting device and the ultrasonic wave receiving device. And the ultrasonic filtering means may be a filtering hole.

As shown, in the disclosed embodiment, holes 3 (filtering holes) are provided on the adsorption structure, so as to filter out the scattered noise, so as to better utilize the ultrasonic wave.

In addition, the embodiment of the present disclosure also provides a scanning apparatus 100, where the scanning apparatus 100 includes:

the paging device 130 as described above;

a page flipping device 140 configured to separate the first and second scan objects at least partially in the non-contact state by an angle; and

an imaging device 150 configured to image the flipped-open first and second scan objects and convert the captured images into digital information.

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