Description

Page turning device with smoothing device and scanning device

Technical Field

The present disclosure relates to the field of scanning technologies, and in particular, to a page turning device with a smoothing device and a scanning device.

Background

For a scanning device with an automatic page turning function, the page turning accuracy and the scanning efficiency are important indexes. In the actual page turning scanning process, as the number of pages to be turned increases, bulges are easy to appear at the position of the page close to the spine, and in order to eliminate the bulges, a scanned object such as a book can rotate along the spine in the continuous page turning process, so that the bulge phenomenon is reduced.

However, during the rotation of the spine, a bulge phenomenon is easily caused at the root of the non-turned page portion.

If the bulge phenomenon occurring in the scanning process is not eliminated, the following problems can occur:

1. the root of the part without page turning bulges to cause the edge of the page to move relatively to the normal condition, and the adsorption position of the sucker arranged on the page turning device is changed compared with the preset position, so that the edge of the page being turned can be adsorbed, and the page turning failure can be caused by air leakage.

2. Due to the bulging phenomenon, the edges of the pages move leftwards in a transient manner relative to a normal condition, and the page pressing mechanism for pressing the pages which are not turned is empty, so that the system receives wrong information, and further excessive adjustment occurs in the subsequent operation processes such as anti-rebound and spine rotation, and the whole scanning process fails.

3. The swelling phenomenon affects the photographing effect.

These resulting problems may eventually lead to scan failures.

The ROM 202, RAM 203, HDD 204, and 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 calculation processing results of the CPU 201 are temporarily stored. The HDD 204 is a storage device in which results of calculation processing by the CPU 201, image data acquired by the imaging apparatus 150, and the like are stored, and is also used to record therein programs for causing the CPU 201 to execute various controls.

The CPU 201 controls the operations of the supporting device 110, the holding device 120, the paging device 130, the page flipping device 140, the imaging device 150, and the anti-bounce device 160 by according to a program recorded in the HDD 204.

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 a paper of a book as an example of a scanning object, the scanning object may be, for example, a newspaper, a photograph, 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 placed on a platform such as a table in a fixed and/or movable manner. A book 180 as a scanning object is supported on the supporting device 110. To facilitate subsequent scanning operations, one side of the book 180 (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 180 to the surface of the supporting device 110, for example, by clamping the spine of the book 180. Alternatively, in the case where the book 180 is a non-registered material, the holding device 110 may fix the scan target by aligning the material and holding one side of the non-registered material.

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

Further, the paging device 130 according to the embodiment of 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.

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 180 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 page bending suction structure supporting device 1403 moves to the position where it contacts the uppermost sheet of the book 180, and when it moves to the position where it contacts the uppermost sheet of the book 180, 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 of the book 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 simultaneously 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.

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 180 to prevent them from being kicked back, facilitating the next page turning. Specifically, each of the

kickback prevention apparatuses

1601 and 1602 includes a rotary device 6012/6022 and a rotary device position adjustment device 6011/6021, the rotary device 6012/6022 is provided in a "Z" shape, one end thereof is fixed to the rotary device position adjustment device 6011/6021, and the height of the fixed position is adjustable, and the other end thereof can press the turned sheets of paper by rotation of the rotary device 6012/6022, thereby preventing the turned sheets from being kicked back. 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 180 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 to but may include, for example, one or more of an electrostatic adsorption device, a magnetic adsorption device, and a biomimetic adsorption device. 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 adsorption force generating device 1304 is merely an example of a separation force generating device configured to generate a separation force that separates adjacent scan objects.

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

In addition, in the description made with reference to fig. 2, 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 shown in fig. 2 may be included in the scope of the page turning device 140.

As described above, during the page-turning scanning process, a phenomenon may occur in which the horizontal page rotates along with the spine of the book and bulges at the root of the non-turned portion. Next, description will be made around the page flipping device 140 to which the scan object flattening portion is attached.

Page turning device

Referring to fig. 3, which shows an example of the page turning device 140 mounted with the scan object flattening portion 200 according to an embodiment of the present disclosure, reference numeral 1001 in the figure indicates a motion trace of the page turning device 140 during performing a page turning operation. The page flipping device 140 may be, for example, the page flipping device described with reference to fig. 2, and the page flipping device 140 performs a page flipping operation to separate a first scanned object (a current page) from a second scanned object (a next page). In other words, the page flipping unit 140 performs a page flipping operation to separate the first scan object from the second scan object.

In this case, the page turning device 140 according to an embodiment of the present disclosure may include a page bending suction structure 1301 and a non-bending page suction structure 1302 as examples of a force applying device (e.g., a suction cup), a page bending suction structure supporting apparatus 1403 as an example of a force applying device mounting part, and a scan object leveling part 200.

In an embodiment of the present disclosure, the force applying device may be, for example, a suction cup and is configured to apply a force to the scan object. In this case, the sheet turning device 140 may suck the uppermost sheet through the suction cup and separate the first scan object (current page) from the second scan object (next page) through a subsequent sheet turning operation.

The force applicator mounting portion may be, for example, the page bending suction structure support device 1403 described with reference to fig. 2. In this case, the force applying device is provided to the force applying device mounting portion, and as shown in fig. 2, the force applying device mounting portion is movable along a trajectory 1001 that is set at a predetermined angle (e.g., 45 °) with respect to the XY plane, thereby moving the power applying device.

In the embodiment of the present disclosure, the scanning object flattening portion 200 may be provided to the force application device mounting portion, and the scanning object flattening portion 200 is provided so as to contact the scanning object prior to the force application device when the force application device mounting portion brings the power application device close to the scanning object.

The term "the scanning object flattening portion may be provided to the force application device mounting portion" may mean either that the scanning object flattening portion is fixed to the force application device mounting portion or that the scanning object flattening portion is connected to the force application device mounting portion via an intermediate structure.

In the disclosed embodiment, when the force-applying device mounting portion brings the force-applying device close to the scanning object (e.g., moves downward along the trajectory in fig. 3), the scanning-object flattening portion is lower than the force-applying device in the Z-axis direction (vertical direction). Specifically, as shown in fig. 3, the scanning object flattening portion 200 is set to be lower H than the force applying device, so that the scanning object flattening portion 200 comes into contact with the scanning object 180 prior to the force applying device in the process of moving the page flipping device 140 downward along the trajectory 1001.

Specifically, since the force application device mounting portion moves along the predetermined trajectory 1001 within the XZ plane (first plane), it is possible to slide on the scanning object during the time when the scanning object flattening portion 200 contacts the scanning object to the time when the force application device contacts the scanning object, thereby eliminating wrinkles, bulges, and the like of the scanning object.

In the embodiment of the present disclosure, the scan object leveling portion may be, for example, an elastic member, and specifically, the scan object leveling portion may be an elastic sheet, a metal sheet, or the like.

In the embodiment of the present disclosure, one end of the elastic member is fixed to the force-applying-device mounting portion (fixed end), and the other end is not constrained (free end), and is disposed in an arc shape in the XZ plane, that is, the elastic member is arranged in the X direction, thereby preventing the elastic member from causing damage to the scanning object due to a difference in the moving direction and the force applying direction during the execution of the leveling operation.

According to a specific implementation manner of the embodiment of the present disclosure, a plurality of scanning object flattening portions may be provided along the Y axis direction, and each scanning object flattening portion is provided in the XZ plane, so that the flattening effect can be further improved by the plurality of scanning object flattening portions.

In this case, the projection lengths of the plurality of scanning target flattening portions in the X direction may be the same. However, it is particularly significant that the projection length devices of the plurality of scan object smoothing parts in the X direction are different, because the scanning apparatus 100 may need to scan books of different sizes (e.g., a4, a5), and the spine position of the a5 paper book is closer to the right side in fig. 2 than the spine position of the a4 paper book when the page turning operation is started, so that if the scan object smoothing part of the a4 paper is used to smooth the a5 paper, the free end of the scan object smoothing part may contact the turned paper, which is not favorable for the smoothing of the paper. In this case, it is required to make the projection in the X direction of the scanning object flattening portion for the a5 sheet shorter than that of the a4 sheet.

Further, in order to adapt the scanning object flattening portions to different sizes of paper, the lengths of projections of the plurality of scanning object flattening portions in the vertical direction (Z-axis direction) may be different. That is, the plurality of scanning object flattening portions are different in height position, and thus, for a large (e.g., a4) sheet, flattening can be performed using a lower scanning object flattening portion, and for a small (e.g., a5) sheet, flattening can be performed using a higher scanning object flattening portion.

Referring to FIG. 4, a schematic view of a page turning device 140 according to another embodiment of the present disclosure is shown. In the above description, the scanning object flattening portion 200 is fixedly mounted to the force application device mounting portion, unlike this, in the embodiment of the present disclosure, the page turning device 140 may further include a driving device 2001 for driving the scanning object flattening portion 200 so that the scanning object flattening portion rotates in the XZ plane, in other words, the scanning object flattening portion is rotatable about the Y axis. At that time, it should be understood that, in the embodiment of the present disclosure, the scanning object flattening portion 200 may also be rotated at an angle (for example, in a range of 0 to 30 °) to the XZ plane.

Specifically, as shown in fig. 4, the driving device 2001 may be directly connected with the scanning object flattening portion 200 to drive the scanning object flattening portion 200. Alternatively, the driving device 2001 may be connected with the scanning object flattening portion 200 via the transmission mechanism 2002.

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

In the case where the driving motor 2001 for driving the scanning object flattening portion 200 is mounted, when the force applying device mounting portion brings the power applying device close to the scanning object (for example, moves downward along a trajectory 1001 in fig. 4), the scanning object flattening portion 200 is lower than the force applying device in the Z-axis direction (vertical direction). Specifically, as shown in fig. 4, the scanning object flattening portion 200 is set to be lower H than the force applying device, so that the scanning object flattening portion 200 comes into contact with the scanning object 180 prior to the force applying device in the process of moving the page flipping device 140 downward along the trajectory 1001.

After the force applying device mounted on the force applying device mounting portion is brought into contact with the scanning object and before the movement along the predetermined trajectory 1001 is started to separate the first scanning object from the second scanning object, in order to prevent the scanning object flattening portion 200 brought into contact with the scanning object when the force applying device mounting portion is brought close to the scanning object at this time from affecting the operation of separating the first scanning object from the second scanning object, the scanning object flattening portion 200 may be driven in advance by the driving apparatus 2001 to separate the scanning object flattening portion 200 from the scanning object.

In addition, in the embodiment of the present disclosure, the paging device 130 may perform a separate paging operation for separating the first scan object from the second scan object by an angle before performing the page turning operation, and then perform the page turning operation by the page turning device. Specifically, before performing a page flipping operation, a paging motor (e.g., 2001) may drive a paging device to move along a predetermined trajectory so that a first scan object is separated from a second scan object by an angle. In this case, the driving device 2001 drives the scanning target flattening section 200 to be separated from the scanning target before the paging device 130 performs the paging operation.

According to a specific implementation manner of the embodiment of the present disclosure, a flexible material may be disposed on an outer surface of the scan object smoothing portion, and the flexible material may be, for example, rubber, sponge, cloth, or the like.

Specifically, a flexible material layer, not shown, is provided on the outer surface of the scanning object leveling portion 200, so that the flexible material layer provided on the outer surface of the scanning object leveling portion 200 can play a role of protecting the pages when leveling the pages, and can make the leveling effect better. In addition, it is preferable that the scan object flattening portion 202 is wrapped with a flexible material layer, but it is also within the scope of the present disclosure to remove the flexible material layer.

According to an embodiment, the flexible material layer is a rubber layer, and the flexible material layer has the functions of protecting the pages on one hand and enabling the page flattening effect to be better when the pages are flattened.

In another preferred embodiment, the transmission mechanism 2002 may be a rigid link mechanism having a driving end connected to the driving motor 2001 and a driven end connected to the scan target flattening portion 200. With the linkage of the rigid link mechanism, the scanning object flattening unit 200 is caused to contact and flatten the scanning object 180 before the force applying device attached portion with the power applying device contacts the scanning object 180, and is caused to separate from the scanning object 180 before the force applying device attached portion with the power applying device separates from the scanning object 180.

In addition, the scanning apparatus according to the present disclosure may further include a controller and a control output device, and the control output device may be any mechanical structure such as a robot arm, a link, or the like, and may be configured to transmit a control operation to the scanning target flattening unit 200. The controller includes a Central Processing Unit (CPU) as a control unit, and specifically, the control output device is connected to the scan object leveling unit 200, a control program is set in the controller through software programming, the scan object leveling unit 200 is controlled to cooperate with the operation of the page turning device 140, the scan object 180 is contacted and leveled before the force applying device is contacted with the scan object 180, and the scan object 180 is detached before the force applying device is detached from the scan object 180. The chip model of the controller can adopt a conventional model, such as 80C51 or 89C 51.

For the purpose of simple design, the above-mentioned scan object flattening portion 200 may be an elastic cushion or a rigid pressing plate, and when the scan object flattening portion 200 is in contact with the scan object 180, the flattening may be achieved. Further, a rigid platen may be used as the scanning target flattening section 200.

In a second aspect, an embodiment of the present disclosure further provides a scanning apparatus, including:

the page turning device according to one or more aspects above; and
