Background

For scanning, the scanning efficiency and the mute effect are important evaluation indexes. Whether paper can be efficiently adsorbed during scanning is important for improving scanning efficiency. The adsorption of paper involves, on the one hand, the time spent on the adsorption itself and, on the other hand, the success rate of the adsorption. Particularly with respect to the success rate of adsorption, a phenomenon in which two or more sheets are adsorbed in one adsorption process due to air permeability of the sheets, vacuum adsorption between the sheets, and electrostatic adsorption easily occurs, which may lead to the need for additional operations such as manual separation, or even to the loss of the contents of the scan results.

Further, although in the above description, the paging device is described as including the inflexible page suction structure 1302 and the air blowing and page pressing device 1303, these components may be omitted without affecting the overall functions of the scanner device 100.

Hereinafter, the present disclosure will be described centering on the paging device 130.

First embodiment

In the scanning process of the scanning apparatus 100, the uppermost sheet and the succeeding sheet need to be separated to realize page-by-page scanning. However, since there is a certain air permeability of the sheet, in the scanner 100 that separates the sheets by vacuum suction, the latter sheet may generate a partial vacuum region around the suction position due to the air permeability of the sheet during suction of the uppermost sheet. The atmospheric air on both sides of the two sheets applies pressure to the partial vacuum area, thereby causing a phenomenon that the latter sheet is absorbed in association with the process of absorbing the uppermost sheet, and thus the sheets cannot be effectively separated. As used herein, the term "air permeability" refers to the average air flow per unit area of paper passing under specified conditions per unit time and per unit pressure differential, expressed in microns/(pascal seconds).

Further, in a configuration in which sheets are separated by a vacuum suction device, in order to have a sufficient suction force to suck the sheets, 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 paper, not all the suckers are contacted with the paper, so that the phenomenon of suction of part of the suckers is caused, and larger noise is generated. For example, in the case where a plurality of suction cups are provided having a width larger than the width of the sheet, the suction cups are all turned on, which results in the suction of a part of the suction cups through holes, resulting in the generation of large noise. Thus, in the present exemplary embodiment, the opening and closing 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 succeeding sheet are effectively separated by providing the dedicated paging device 130 for the paging operation, unlike the uppermost sheet and the succeeding sheet being separated directly by the page turning operation, in the present exemplary embodiment, the term "separated" means at least partially in a non-bonded 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 line 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 schematic structural view of the page-bending suction structure 1301 as viewed from the upper side, and fig. 4 shows a schematic structural view of the page-bending suction structure 1301 as viewed from the lower side. Wherein the lower side refers to the side in contact with the paper and the upper side is the 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 lever 3015, a pressing plate 3016, a cushion pad 3017, a second slide rail 3018, a suction cup mounting nut 3019, a limit switch 3020, and a traction 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 mounting portion 3024.

The suction cup mounting portion 3011 mounts a suction cup 3022, and the suction cup 3022 applies suction force to the sheet. During suction, the lower surfaces of the suction cup mounting portion 3011 and the pressure plate 3016 may lie in the same plane to be in contact with the plane of the paper sheet at the initial suction position. Specifically, during paging, the longitudinal direction of the suction cup mounting portion 3011 and the pressure plate 3016 coincides with the longitudinal direction of the sheet (the gripping direction of the sheet), and when the pressure plate 3016 of the page bending suction structure 1301 is in contact with the sheet, the contact determination switch 3023 provided on the pressure plate 3016 is touched, whereby the current position is determined to be the position where the page bending suction structure 1301 is in contact with the sheet, and the current position is set as the suction initial position.

Here, it is not necessary that both the pressing 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 paper.

A suction cup 3022 or other suction structure is provided on the lower surface of the suction cup mounting portion 3011 to suck the sheet at the initial suction position by suction force generated by, for example, the suction force generating device 1304. In the present exemplary embodiment, the suction cup 3022 is taken as an example of a force applying means configured to apply the suction force generated by the suction force generating 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 whole page bending suction structure 1301.

The suction cup mounting portion 3011 may be made of a lightweight material such as resin, aluminum alloy, or the like, and is preferably capable of withstanding bending moments. 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 that sucks paper (such as a Miaode vacuum suction cup PAG-8). Suction cup 3022 may be mounted on suction cup mounting portion 3011 by suction cup mounting nut 3019, for example.

The press plate 3016 may be configured to press the paper before or during the paging operation to prevent wrinkling of the paper, etc. The pressure plate 3016 is connected to the suction cup mounting portion 3011 by 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 walls 3013, and two slide bearings (sliding portions) are provided at each longitudinal end of the suction cup mounting portion 3011, which are mounted in the first slide rail 3012 and the second slide rail 3018, respectively, so that the suction cup mounting portion 3011 can move relative to the pressing plate 3016 along a trajectory defined by the first slide rail 3012 and the second slide rail 3018.

Further, in order to enable resetting of the suction cup mounting portion 3011 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 lever 3015, one end of the spring mounting lever 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 pressing plate 3016. In addition, a spring, not shown, is mounted on the spring mounting rod 3015, and thus, the spring is compressed during movement of the suction cup mounting portion 3011 relative to the press plate 3016 along a trajectory defined by the first slide rail 3012 and the second slide rail 3018. When the paging operation is finished, the suction cup mounting portion 3011 is reset by the resilience of the spring.

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

In order to limit the limit position of movement during the movement of the suction cup mounting portion 3011, on the one hand, it can be controlled by a limit switch 3020 provided on the suction cup mounting portion 3011. Specifically, for example, a photoelectric switch is provided on the pressure 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 action. On the other hand, the pressing plate 3016 according to the present exemplary embodiment is further provided with a cushion pad 3017, and when the suction cup mounting portion 3011 is moved to a position contacting the cushion pad 3017, the movement of the suction cup mounting portion 3011 relative to the pressing plate 3016 is stopped by means of physical limitation.

Hereinafter, the positional arrangement of the suction pads 3022 of the page bending suction structure 1301 and the movement of the suction pad mounting portion 3011 (i.e., the suction pads 3022) in the paging operation according to the present exemplary embodiment are described.

Referring to fig. 5, a state diagram of the current sheet P1 and the subsequent sheet P2 during adsorption of the current sheet P1 is shown. In fig. 5, A1 indicates a suction area of the suction cup 3022 on the suction cup mounting portion 3011. Since the paper has air permeability, air existing between the paper P1 and P2 is permeated through the paper P1 upon adsorption, thereby creating a partial vacuum between the paper P1 and P2. In fig. 5, a region A2 indicates a partial vacuum region between the sheets P1 and P2. In this manner, in the case where the sheets P1 and P2 are separated by a usual page turning action (for example, the current sheet P1 is sucked by a suction cup and moved upward along a slide rail on the driving structure moving device 1401 by the page bending suction structure supporting device 1403), there is a strong attraction force between the sheets P1 and P2 because the partial vacuum area A2 is formed between the sheets P1 and P2. And the separating force existing between P1 and P2 is mainly the self weight of the paper P2. Since the self weight of the paper P2 is much smaller than the adsorption force between P1 and P2, effective separation between the paper P1 and P2 cannot be achieved, which seriously affects the scanning efficiency. In fig. 5, although the area of A1 is shown to be smaller than A2, the present invention is not limited thereto, and the area of A1 may be equal to or larger than the area of A2.

For this reason, the scanner apparatus 100 according to the present exemplary embodiment is provided with the paging apparatus 130, and the paging apparatus 130 is mainly used to effectively separate the sheets P1 and P2 before the page turning operation is performed by the page turning apparatus 140. Specifically, in the present exemplary embodiment, the paging operation is realized by the page-bending adsorption structure 1301 described above.

In the case where the sheets P1 and P2 are sucked together due to the partial vacuum area A1 as shown in fig. 5, the paging device 130 according to the present exemplary embodiment achieves effective separation of the sheets P1 and P2 by the paging action. Specifically, the paging action includes an adsorption action and a bending action.

In the suction action, the suction cup 3022 of the page bending suction structure 1301 contacts with the sheet to suck the sheet. In the following bending action, in order to provide an additional separating force to separate the sheets P1 and P2, in the present exemplary embodiment, effective separation of the sheets P1 and P2 is achieved by the sheets themselves having a certain rigidity. Specifically, as shown in fig. 6, it shows a case where the sheet P1 is bent at a radius, where the point O is a bending point. Due to the presence of the partial vacuum region A1, the sheet P2 is also subjected to vacuum suction force, vacuum suction force and electrostatic suction force between the sheets themselves, and the like, and the resultant force F1 of these forces can be regarded as the resultant force of suction forces acting on the sheet P2 in the presence of the partial vacuum region. Further, in the process in which the sheet P2 is lifted by suction with the sheet P1, the sheet P2 is also subjected to the gravity G and the repulsive force F2 derived from the rigidity of the sheet P2, and when the moment M2 generated by the gravity G and the repulsive force F2 is larger than the moment M1 generated by the resultant force F1, the sheet P2 can be separated from the sheet P1.

As shown in fig. 6, in the case where the power of the suction force generating device 1304 is constant, the magnitude of the resultant force F1 generated remains substantially unchanged, and the magnitude of the moment M1 can be influenced by the distance L1 of the resultant force F1 from the fulcrum O, that is, the bending radius. Specifically, the larger L1, the larger the moment M1, the smaller L1, and the smaller M1. It follows that the value of the distance L1 is desirably as small as possible, that is, the suction position of the suction cup 3022 provided on the suction cup mounting portion 3011 is as low as possible from the sheet bending position.

Further, if the partial vacuum region A1 can be made to communicate directly with the outside atmosphere, the formation of the partial vacuum region A1 can be broken, thereby greatly reducing the force F1. In view of this, it is possible to prevent the suction between the sheets P1 and P2 due to the formation of the partial vacuum area A1 by setting the suction position of the suction cup 3022 at the edge of the sheet so that in the case of sucking the sheet P1 by the suction cup 3022, the outside atmosphere may enter the suction cup 3022 through the gap between the sheets P1 and P2, so that the formation of the partial vacuum area A1 between the sheets P1 and P2 can be destroyed. According to one embodiment, suction cup 3022 is arranged such that the distance from the edge of the paper is less than 6cm, for example 5cm, 3cm, 1cm, 0.15cm, etc.

On the other hand, the greater the weight G and the repulsive force F2 of the sheet, the more easily the sheet P2 is separated from the sheet P1. The grammage remains substantially uniform for a particular sheet, and thus the factor affecting weight G is the sheet bending position. As for the repulsive force F2, the smaller the distance of the force F1 that deflects the sheet P2 from the fulcrum (point O in the present exemplary embodiment), the larger the repulsive force F2. And the weight G of the paper is substantially negligible compared to the rebound force F2. That is, in the present exemplary embodiment, the sheets are separated mainly by the repulsive force F2 of the sheets. In order to increase the repulsive force F2, the suction position of the suction cup should be as close to the sheet bending position as possible, that is, the bending radius of the sheet should be as small as possible.

The threshold radius for effective separation of different types of paper is different for the bend radius. In this context, the threshold radius refers to the maximum value of the bending radius at which the paper sheets P1 and P2 are separated by more than 90%, 95%, 99%, or other value. For example, the threshold radius is small for tissue paper because of its high air permeability. For thicker papers, which have a small air permeability, only a relatively large threshold radius is required to effectively separate papers P1 and P2. The threshold radius for the effective separation for different types of paper may be obtained, for example, by a preliminary experiment, and may be stored in memory, for example, in the form of a look-up table. That is, the threshold radius is paper-based.

In the above embodiment, the sheet is effectively separated by first adsorbing the sheet and then bending the sheet at a predetermined radius, and thus, since the sheet is first attached to the sheet and then adsorbed, only a small adsorption power is required, noise can be reduced. In addition, after the suction cup 3022 reaches the position of contact with the sheet, the suction cup 3022 in contact with the sheet is turned on, and the suction cup 3022 not in contact with the sheet is turned off, so that suction of the suction cup 3022 is avoided, thereby further reducing noise of the apparatus.

Next, the movement of the suction cup mounting portion 3011 (i.e., suction cup 3022) during paging will be mainly described.

In the present exemplary embodiment, the movement of the suction cup mounting portion 3011 is defined by a first slide rail 3012 and a second slide rail 3018 provided on the side wall 3013. In particular, referring to FIG. 7, a side view of side wall 3013 is shown. As shown in the drawing, on the side walls 3013, a first slide 3012 and a second slide 3018 are provided, and two rolling bearings mounted at both ends of the suction cup mounting portion 3011 are mounted in the first slide 3012 and the second slide 3018, respectively, so that during paging, the suction cup mounting portion 3011 moves along a track defined by the first slide 3012 and the second slide 3018, thereby separating the sheets P1 and P2.

According to one embodiment, to prevent the suction cup 3022 and the sheet from sliding relatively, the first slide 3012 and the second slide 3018 need to satisfy a specific condition. Further, in the case where the suction cup 3022 and the sheet do not slide relatively, the movement locus of the suction cup 3022 is rolling with respect to a plane parallel to the plane of the sheet.

In the present exemplary embodiment, the rolling movement of the suction cup 3022 is achieved by the arrangement of the first slide 3012 and the second slide 3018. The conditions that the first and

second slide rails

3012 and 3018 should satisfy are described next with reference to fig. 8. An XY coordinate system as shown in fig. 8 is set, and in the present exemplary embodiment, the outer diameter of the slide bearing is set to b, so that the movement locus of the suction cup 3022 is rolling with respect to a plane at a distance b from the plane of the sheet.

Further, although the present disclosure is described taking an example in which the tilting movement of the suction cup mounting portion 3011 is defined by the first slide rail 3012 and the second slide rail 3018, the present invention is not limited thereto. For example, rolling movement of the sheet can be ensured by rotating the suction cup mounting portion 3011 while moving the suction cup mounting portion 3011 in the horizontal direction by a motor. Further, although the limitation of the movement of the suction cup 3022 is described in the form of two slide rails of the first slide rail 3012 and the second slide rail 3018, the number of slide rails is not limited thereto, and may be one or more slide rails, for example, as long as the slide rails can realize the rolling movement of the sheet.

In addition, the rolling of the paper can be ensured by adopting other modes.

In another embodiment, suction cup 3022 may be rotated relative to an axis parallel to the plane of the sheets, and effective separation between sheets P1 and P2 may be achieved as long as the radius of rotation is less than the threshold radius.

Second embodiment

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

In a second embodiment according to the present disclosure, the paging apparatus 130 further includes a margin determination device. The margin determination 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 gripping end.

As described above, in order to improve the paging efficiency, the suction force between the sheets P1 and P2 can be reduced by suppressing the formation of the partial vacuum region A2. In the present exemplary embodiment, the suction position of the suction cup 3022 is set at the edge position of the sheet, and thus, during suction, the outside atmosphere can enter the partial vacuum area A2 only by a short stroke, thereby suppressing suction between the sheets P1 and P2.

Specifically, in the present exemplary embodiment, the margin determination device may be configured by a luminance sensor. For example, a luminance sensor may be mounted on the lower surface of the suction cup mounting portion 3011, and a distance from the center position of the suction cup is fixed. In the suction operation, the lower surface of the suction cup mounting portion 3011 is first not in contact with the sheet, but is moved in the X direction, for example, in the case where the change in luminance detected by the luminance sensor is greater than a predetermined value, it is determined that the position where the luminance sensor is located has reached the edge of the sheet, and then the suction cup position is moved to a predetermined position by motor control or the like.

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

In the present exemplary embodiment, the suction cup is placed at a position just inside the sheet, i.e., the edge of the suction cup just contacts the edge of the sheet. In this way, the possibility of forming the partial vacuum area A2 between the sheets P1 and P2 can be reduced to the maximum, thereby further improving the efficiency of the paging.

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

Third embodiment

In the following, description is made mainly focusing on differences from the first and second embodiments in order to avoid unnecessarily obscuring the present disclosure, and parts not specifically described may be the same as in the first and second embodiments.

In the above description, the separation operation of the sheet is described taking the suction of the suction cup 3022 as an example, but other suction means such as electrostatic suction, magnetic suction, bionic suction, or the like may be employed as long as the suction position of these suction means and the movement means of the suction cup mounting portion can satisfy the above description with reference to the first embodiment and the second embodiment.

In the case of adsorbing the paper by other means, the adsorption force generating device 1304 may be, for example, a corresponding electrostatic generating device, magnetic generating device, bionic force generating device, or the like, and the resultant force F1 may be the attractive force between the paper P1 and P2 in the corresponding case.

In the present exemplary embodiment, a nanosticker (also referred to as a hand-held sticker or a removable adhesive) is used instead of a vacuum chuck to adhere paper. In the case of using the nanoadhesive, the nanoadhesive is both an adsorption force generating device and a force applying device.

The paging operation of the paper by the nano adhesive has the advantages of high success rate and low noise. However, since the paper structure is fibrous, the surface of the nanosticker may adhere to fine fibers detached from the paper after multiple adsorption, resulting in insufficient adhesion, and the paging effect is remarkably deteriorated after about 10 paging operations through experimental test. Therefore, the nano-adhesive tool can be provided with the cleaning device, and can be put into use again after being cleaned by clean water and dried. 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 nanosticker, a cleaning device may be provided for other types of force generating devices according to the invention.

Although the present disclosure has been described with reference to example embodiments, it is to be understood that the invention is not limited to the disclosed example embodiments.
