First embodiment

In the scanning process of the scanning device 100, it is necessary to separate the uppermost paper from the next paper to realize page-by-page scanning. However, because the paper has a certain degree of air permeability, in the scanning device 100 that separates the paper by vacuum suction, the latter paper may be generated around the suction position due to the air permeability of the paper during the adsorption of the uppermost paper. Partial vacuum area. The atmosphere on both sides of the two sheets of paper will exert pressure on the partial vacuum area, which will cause the subsequent sheet to be adsorbed in the process of adsorbing the uppermost sheet, so that the sheets cannot be effectively separated. In this article, the term "air permeability" refers to the average air flow rate per unit area of paper under specified conditions, unit time and unit pressure difference, and its unit is expressed in microns/(Pascal·sec).

In addition, in a configuration where the paper is separated by a vacuum suction device, in order to have sufficient suction force to suck the paper, a plurality of suction cups are usually provided to suck the paper, and the plurality of suction cups may be arranged in a row, for example. In the process of sucking the paper, not all the suction cups will come into contact with the paper, which will cause some suction cups to appear empty, which will generate a lot of noise. For example, in the case where the width of the plurality of suction cups is greater than the width of the paper, opening the suction cups completely will cause the holes of the suction cups to suck, resulting in large noise. Therefore, in this exemplary embodiment, the switches of the plurality of suction cups are controllable, that is, the suction force exerted on the paper by the suction cups is controllable.

In this exemplary embodiment, unlike the direct page turning operation to separate the uppermost paper from the next paper, a special paging device 130 is provided for the paging operation to effectively separate the uppermost paper from the next paper. In the present exemplary embodiment, the term "separated" means at least partially in a non-adhering 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 pipe 1305 included in the paging device 130 may be the same as those described above with reference to FIG. 2, and the following description mainly focuses on the page bending suction structure 1301.

3 and 4 show views of the page bending suction structure 1301 according to this exemplary embodiment, in which FIG. 3 shows a schematic diagram of the page bending suction structure 1301 viewed from the upper side, and FIG. 4 shows The schematic diagram of the page bending suction structure 1301 viewed from the bottom side. 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 this exemplary embodiment includes a suction cup mounting portion 3011, a first slide rail 3012, a side wall 3013, a stop portion 3014, a spring mounting rod 3015, a pressure plate 3016, and a cushion 3017 , The second slide rail 3018, the suction cup mounting nut 3019, the limit switch 3020 and the traction part 3021. In addition, as shown in FIG. 4, the page bending suction structure 1301 according to this exemplary embodiment further includes a suction cup 3022, a contact determination switch 3023, and a stop portion mounting portion 3024.

The suction cup 3011 is installed with a suction cup 3022, and the suction cup 3022 applies suction force to the paper. During the suction process, the suction cup mounting portion 3011 and the lower surface of the pressing plate 3016 may be in the same plane so as to be in contact with the paper plane at the initial suction position. Specifically, in the paging process, the longitudinal direction of the suction cup mounting portion 3011 and the pressing plate 3016 is consistent with the longitudinal direction of the paper (the paper clamping direction), and when the pressing plate 3016 of the page bending suction structure 1301 contacts the paper, the pressing plate 3016 is touched The contact determination switch 3023 is set on the upper side to determine that the current position is the position where the page bending suction structure 1301 contacts the paper, and the current position is set as the suction initial position.

Here, it is not necessary for both the pressing plate 3016 and the suction cup mounting part 3011 to press the surface of the paper, and it is sufficient that the lower surface of the suction cup mounting part 3011 presses the surface of the paper. However, it is preferable that the pressing plate 3016 and the suction cup mounting portion 3011 press the paper surface.

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

The suction cup mounting portion 3011 may be made of, for example, a lightweight material such as resin and aluminum alloy, and preferably can withstand bending moment. The suction cup 3022 may be, for example, a rubber suction cup, a sponge suction cup, an anti-static suction cup, etc., and may be a special suction cup for sucking paper (such as a Magic vacuum suction cup PAG-8). The suction cup 3022 can be mounted on the suction cup mounting portion 3011 through a suction cup mounting nut 3019, for example.

The pressing plate 3016 may be configured to press the paper before or during the paging operation to prevent the paper from wrinkling or the like. The pressing plate 3016 and the suction cup mounting portion 3011 are connected by a side wall 3013. Specifically, in this exemplary embodiment, a first slide rail 3012 and a second slide rail 3018 are provided on the side wall 3013, and two sliding bearings (sliding bearings) are provided at each longitudinal end of the suction cup mounting portion 3011. Section), the two sliding bearings are installed in the first slide rail 3012 and the second slide rail 3018, so that the suction cup mounting portion 3011 can be relative to the track defined by the first slide rail 3012 and the second slide rail 3018 The pressing plate 3016 moves.

In addition, in order to enable the suction cup mounting portion 3011 to be reset to perform the next paging operation after the current paging operation is completed, the page bending suction structure 1301 according to this exemplary embodiment includes a spring mounting rod 3015, one end of the spring mounting rod 3015 and the suction cup The mounting portion 3011 is hinged, and the other end is mounted in a hole in the stop portion 3014 via a sliding bearing, and the stop portion 3014 is hinged with the stop portion mounting portion 3024, and the stop portion mounting portion 3024 is fixedly connected with the pressure plate 3016. In addition, an unshown spring is installed on the spring mounting rod 3015. Thus, when the suction cup mounting portion 3011 moves relative to the pressure plate 3016 along the track defined by the first slide rail 3012 and the second slide rail 3018, the spring Is compressed. After the paging operation is finished, the sucker mounting portion 3011 is reset by using the resilience of the spring.

In this exemplary embodiment, the pulling part 3021 provided on the suction cup mounting part 3011 is pulled by a pulling rope or the like to realize the movement of the suction cup mounting part 3011 relative to the pressing plate 3016. The traction action can be realized by a motor or the like, for example.

During the movement of the suction cup mounting portion 3011, in order to limit the limit position of the movement, 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. When the limit switch 3020 on the suction cup mounting portion 3011 moves to a specific position with the suction cup mounting portion 3011, the photoelectric switch will be cut off, thereby causing the suction cup mounting portion 3011 to be pulled. The motor stops traction. On the other hand, the pressure plate 3016 according to the present exemplary embodiment is also provided with a cushion 3017. When the suction cup mounting portion 3011 is moved to a position in contact with the cushion 3017, the suction cup mounting portion 3011 is physically restricted to be relative to The movement of the pressing plate 3016 stops.

Hereinafter, the position arrangement of the suction cup 3022 of the page bending suction structure 1301 and the movement of the suction cup mounting portion 3011 (ie, the suction cup 3022) in the paging operation according to the present exemplary embodiment are described.

Referring to FIG. 5, it shows a state diagram of the current paper P1 and the next paper P2 during the adsorption of the current paper P1. In FIG. 5, A1 indicates the suction area of the suction cup 3022 on the suction cup mounting portion 3011. Due to the air permeability of the paper, the air existing between the paper P1 and P2 will pass through the paper P1 when adsorbed, thereby causing a partial vacuum between the paper P1 and P2. In FIG. 5, the area A2 indicates the partial vacuum area between the sheets P1 and P2. In this way, in the case of separating the paper P1 and P2 through the usual page turning action (for example, the current paper P1 is adsorbed by the suction cup, and the page bending suction structure supporting device 1403 moves upward along the sliding rail on the driving structure movement device 1401), Since a partial vacuum area A2 is formed between the paper P1 and P2, there is a strong attraction force between the paper P1 and P2. The separation force between P1 and P2 is mainly the weight of the paper P2. Since the weight of the paper P2 is much smaller than the adsorption force between P1 and P2, it is impossible to achieve effective separation between the paper P1 and P2, which will seriously affect the efficiency of scanning. In FIG. 5, although the area of A1 shown is smaller than that of A2, the present invention is not limited to this, and the area of A1 may be equal to or larger than the area of A2.

To this end, the scanning device 100 according to this exemplary embodiment is provided with a paging device 130, which is mainly used to effectively separate the papers P1 and P2 before the page turning device 140 performs a page turning operation. Specifically, in this exemplary embodiment, the paging operation is realized by the page bending suction structure 1301 as 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 realizes the effective separation of the sheets P1 and P2 through a paging action. Specifically, the paging action includes a suction action and a bending action.

In the suction action, the suction cup 3022 of the page bending suction structure 1301 contacts the paper to suck the paper. In the subsequent bending action, in order to provide additional separation force for the separation of the papers P1 and P2, in this exemplary embodiment, the paper itself has a certain rigidity to realize the effective separation of the papers P1 and P2. Specifically, as shown in FIG. 6, it shows a situation in which the paper P1 is bent with a radius, where the point O is the bending point. Due to the presence of the partial vacuum area A1, the paper P2 is also subject to vacuum adsorption force, vacuum adsorption force between the paper itself, and electrostatic adsorption force. The resultant force F1 of these forces can be regarded as acting on the paper P2 in the presence of a partial vacuum area. The resultant force of the adsorption force. In addition, when the paper P2 is sucked and lifted with the paper P1, the paper P2 is also subjected to the gravity G and the rigid resilient force F2 derived from the paper P2. When the gravity G and the resilient force F2 generate a moment M2 greater than the resultant force F1 When the moment M1 is generated, the paper P2 can be separated from the paper P1.

As shown in Figure 6, when the power of the adsorption force generating device 1304 is constant, the magnitude of the resultant force F1 generated remains basically unchanged, and the amount that can affect the magnitude of the moment M1 is the distance L1 between the resultant force F1 and the fulcrum O, that is Bend radius. Specifically, the larger the L1, the larger the moment M1, the smaller the L1, the smaller the M1. Therefore, it can be seen 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 small as possible from the paper bending position.

In addition, if the partial vacuum area A1 can be directly connected to the outside atmosphere, the formation of the partial vacuum area A1 can be destroyed, thereby greatly reducing the force F1. In view of this, the suction position of the suction cup 3022 can be set at the edge of the paper, so that when the paper P1 is sucked by the suction cup 3022, the outside atmosphere may enter the suction cup 3022 through the gap between the paper P1 and P2. The formation of the partial vacuum area A1 between the paper P1 and P2 is destroyed, and the adsorption of the paper P1 and P2 due to the formation of the partial vacuum area is prevented. According to one embodiment, the suction cup 3022 is arranged such that the distance from the edge of the paper is less than 6 cm, for example 5 cm, 3 cm, 1 cm, 0.15 cm, etc.

On the other hand, the greater the weight G and the resilience F2 of the paper, the easier the paper P2 is separated from the paper P1. For a specific paper, its weight is basically the same, so the factor that affects the weight G is the bending position of the paper. Regarding the resilience force F2, the smaller the distance from the fulcrum (point O in this exemplary embodiment) from the force F1 that causes the paper P2 to bend, the greater the resilience force F2. And compared with the resilience F2, the weight G of the paper is basically negligible. That is to say, in this exemplary embodiment, the paper is separated mainly by the resilience F2 of the paper. In order to increase the resilience force F2, the suction position of the suction cup should be as close as possible to the bending position of the paper, that is, the bending radius of the paper should be as small as possible.

For the bending radius, different types of paper have different effective separation threshold radii. In this article, the threshold radius refers to the maximum value of the bending radius when the separation success rate of the paper P1 and P2 is greater than 90%, 95%, 99% or other values. For example, thin paper has a small threshold radius due to its high air permeability. For thicker papers with low air permeability, only a relatively large threshold radius is required to effectively separate the papers P1 and P2. For different types of paper, the effective separation threshold radius can be obtained, for example, through preliminary experiments, and the threshold radius can be stored in the memory in the form of a lookup table, for example. In other words, the threshold radius is based on the paper.

In the above embodiment, the paper is effectively separated by first sucking the paper and then bending the paper with a predetermined radius. In this way, since it is first attached to the paper and then sucked, only a small suction power is required, so noise can be reduced. . In addition, after the suction cup 3022 reaches the position in contact with the paper, the suction cup 3022 in contact with the paper is opened, and the suction cup 3022 not in contact with the paper is closed. In this way, the suction cup 3022 is prevented from being sucked, thereby further reducing the noise of the device. .

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

In this exemplary embodiment, the movement of the suction cup mounting portion 3011 is defined by the first slide rail 3012 and the second slide rail 3018 provided on the side wall 3013. Specifically, refer to FIG. 7, which shows a side view of the side wall 3013. As shown in the figure, on the side wall 3013, a first slide rail 3012 and a second slide rail 3018 are provided, and two rolling bearings installed at both ends of the suction cup mounting portion 3011 are installed on the first slide rail 3012 and the second slide rail respectively. In the rail 3018, in this way, during the paging process, the suction cup mounting portion 3011 moves along the track defined by the first slide rail 3012 and the second slide rail 3018, thereby separating the paper sheets P1 and P2.

According to one embodiment, in order to prevent relative sliding of the suction cup 3022 and the paper, the first slide rail 3012 and the second slide rail 3018 need to meet certain conditions. Further, when the suction cup 3022 and the paper do not slide relative to each other, the movement track of the suction cup 3022 is a rolling relative to a plane parallel to the plane where the paper is located.

In this exemplary embodiment, the rolling motion of the suction cup 3022 is realized by the arrangement of the first slide rail 3012 and the second slide rail 3018. Next, the conditions that the first slide rail 3012 and the second slide rail 3018 should meet are described with reference to FIG. 8. Set the XY coordinate system as shown in FIG. 8, and in this exemplary embodiment, the outer diameter of the sliding bearing is set to b. Thus, the movement trajectory of the suction cup 3022 is relative to the plane at a distance b from the plane of the paper. scroll.

In addition, although the present disclosure has been described by taking the first slide rail 3012 and the second slide rail 3018 to define the turning movement of the suction cup mounting portion 3011 as an example, the present disclosure is not limited thereto. For example, the motor can rotate the suction cup mounting portion 3011 while moving the suction cup mounting portion 3011 in the horizontal direction to ensure the rolling motion of the paper. In addition, although the limitation on 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 to this, for example, it may be one or more slide rails. , As long as the slide rail can realize the rolling motion of the paper.

In addition, other methods can also be used to ensure the rolling of the paper.

In another embodiment, the suction cup 3022 can be made to rotate relative to an axis parallel to the plane where the paper is located, and an effective separation between the paper P1 and P2 can also be achieved, as long as the radius of rotation is smaller than the threshold radius.

Second embodiment

In the following, the second embodiment according to the present disclosure is described. In order to avoid unnecessarily obscuring the present disclosure, in the following description, the description will mainly focus on the differences from the first embodiment, and the parts that are not specifically described may be different from the first embodiment. The same in the embodiment.

In the second embodiment according to the present disclosure, the paging device 130 further includes a margin determination device. The margin determination device is mainly used to determine the distance between the suction cup 3022 and the edge of the paper, specifically, the distance between the suction cup 3022 and the edge of the end of the paper opposite to the clamping 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 area A2. In this exemplary embodiment, the suction position of the suction cup 3022 is set at the edge position of the paper, so that during the suction process, the outside atmosphere can enter the partial vacuum area A2 only through a short stroke, thereby suppressing Adsorption between paper P1 and P2.

Specifically, in this exemplary embodiment, the margin determination device can be configured by a brightness sensor. For example, the brightness sensor may be installed on the lower surface of the suction cup mounting part 3011 with a fixed distance from the center position of the suction cup. During the suction operation, the lower surface of the suction cup mounting portion 3011 does not first contact the paper, but moves along the X direction. For example, when the brightness change detected by the brightness sensor is greater than a predetermined value, the location of the brightness sensor is determined The edge of the paper has been reached, and the suction cup is moved to a predetermined position through motor control.

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

In this exemplary embodiment, the suction cup is placed at a position just inside the paper, that is, the edge of the suction cup is just in contact with the edge of the paper. In this way, the possibility of forming a partial vacuum area A2 between the paper P1 and P2 can be minimized, thereby further improving the efficiency of paging.

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

The third embodiment

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

In the above description, the paper separation operation is described by taking the suction of the suction cup 3022 to the paper as an example, but other suction methods can be used, such as electrostatic, magnetic, bionic, etc., as long as the suction positions of these suction methods and The movement mode 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 static electricity generating device, a magnetic generating device, a bionic force generating device, etc., and the resultant force F1 may be the paper P1 and P2 in the corresponding situation. The attraction between.

In this exemplary embodiment, instead of vacuum suction cups, nano-adhesive tools (also referred to as hand stickers or removable glue) are used to adhere the paper. In the case of using the nano-sticker, the nano-sticker is both an adsorption force generating device and a force applying device.

The paging operation of the paper through the nano-sticker has the advantages of high success rate and low noise. However, because the paper structure is fibrous, after multiple adsorptions, the surface of the nano-adhesive may adhere to the fine fibers that fall off the paper, resulting in insufficient adhesion. After about 10 paging operations in experimental tests, The paging effect is obviously degraded. Therefore, a cleaning device can be provided for the nano-adhesive tool, and the nano-adhesive tool can be reused after being cleaned with water and dried. The paging device designed in this way has a high paging success rate, and the noise can be kept between 45dB-55dB. .

In addition, in addition to providing a cleaning device for the nanosticker, it is also possible to provide a cleaning device for other types of force generating equipment according to the present invention.

Although the present disclosure has been described with reference to example embodiments, it should be understood that the present invention is not limited to the disclosed example embodiments. The scope of the appended claims should be given the broadest interpretation so as to include all such modifications and equivalent structures and functions.
