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.

Specifically, in this exemplary embodiment, the first slide rail 3012 and the second slide rail 3018 are arranged such that the movement of the suction cup mounting portion 3011 enables the suction cup 3022 to move in the direction of the suction force of the suction cup 3022 on the paper. That is, the suction cup 3022 moves in a direction perpendicular to the suction position.

Although it is described above that the suction cup 3022 is moved in the direction perpendicular to the suction position through the first slide rail 3012 and the second slide rail 3018, the present invention is not limited to this, but for example, the suction cup mounting portion 3011 can be driven to rotate by controlling The motor to make the suction cup 3022 move in a direction perpendicular to the suction position.

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 paper 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, so that the suction cup mounting portion 3011 is 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.

Auxiliary paging device 1303

In FIG. 2, the blowing and pressing device 1303 as an auxiliary paging device is fixedly arranged in the vertical direction, but the present invention is not limited to this. In this exemplary embodiment, the auxiliary paging device is installed on the suction cup mounting part 3011 together with the suction cup to follow the suction cup 3022 to move during the entire paging process, so as to be able to blow between the current paper and the next paper during the entire paging process. Gas, thereby increasing the success rate of paging.

Specifically, in this exemplary embodiment, the wind generating device 3031 of the blowing page pressing device 1303 may be fixedly installed on the suction cup mounting part 3011 or the rack of the scanning device, and the blowing port 3032 is fixedly installed on the suction cup mounting part. On 3011, when the suction cup 3022 moves along the sliding rail set on the driving structure movement device 1401 with the suction cup 3022 as the paper bends, the suction structure support device 1403 moves along with the air blowing port 3032, so that during the entire movement process (the paging process), The air flow from the blowing port 3032 can be guided between the current paper and the next paper.

Further, in this exemplary embodiment, the blowing port 3032 and the suction cup 3022 are both fixedly installed on the suction cup mounting portion 3011, and the blowing port 3032 is fixed relative to the suction cup 3022, and in the process of separating the current sheet from the next sheet , The air blowing port 3032 follows the movement of the suction cup 3022, and then follows the movement of the paper sucked by the suction cup 3022, so as to blow air between the current paper and the next paper during the entire paging process, thereby improving the success rate of paging.

In this exemplary embodiment, the air blowing port 3032 may be set to directly blow air between the current paper and the next paper. In this case, the air blowing port 3032 is set to be opposite to the edges of both the current paper and the next paper (as shown in FIG. 6). In another embodiment, the air blowing port 3032 may not be opposed to the edges of both the current paper and the next paper, but the air flow from the air blowing port is guided between the current paper and the next paper through the air guide part. It can blow air between the current paper and the next paper when the air outlet does not exceed the scope of the paper, thereby saving the internal space of the scanning device and reducing the possibility of interference between the air outlet 3032 and other components provided in the scanning device Sex.

The air flow guide may be, for example, a baffle provided on one side of the suction cup mounting part 3011, and the air flow from the blowing port 3032 is guided by the baffle between the current paper and the next paper. In this way, the setting of the blowing port 3032 is realized. The effect of directing the airflow between the current paper and the next paper when it is within the range of the paper.

In the present invention, the term "blowing device" may individually indicate the blowing port 3032 installed on the suction cup mounting portion 3011, or may indicate both the wind generating device 3031 and the blowing port 3032. As long as the blowing device can follow the movement of the current paper during the entire scanning process, so as to supply airflow between the current paper and the next paper.

In this exemplary embodiment, since the blowing port 3032 follows the current paper movement during the paging process, the blowing port 3032 is fixed relative to the position of the current paper that is sucked by the suction cup 3022. Specifically, in the present exemplary embodiment, the suction position of the suction cup 3022 is set at a position close to the edge of the paper, so that the blowing port 3032 is substantially fixed with respect to the edge of the paper.

In this case, the air flowing out from the blowing port 3032 flows between the current paper and the next paper in the direction opposite to the edge of the paper (the direction from the outside of the book 201 to the edge of the paper and pointing into the book 201). Since the blowing port 3032 is basically fixed relative to the edge of the paper, the direction of the airflow is also basically fixed relative to the edge of the paper.

As shown in FIG. 5, it shows the blowing direction of the air flow out of the blowing port 3032. As shown on the right side of Figure 5, when the blowing direction and the plane of the current paper are within ±90°, the airflow can flow between the current paper and the next paper, thereby increasing the success rate of separation between the two . Preferably, the angle between the air flow out of the air outlet of the blowing device and the plane of the current paper is within the range of ±60°, ±30°, or ±10°. More preferably, the air flow from the air outlet of the blowing device is parallel to the plane where the current paper is located.

When the airflow is guided by the airflow guide, the angle when the airflow contacts the current paper is within the range of ±90°, ±60°, ±30°, or ±10°, or the airflow is parallel to the plane of the current paper.

In this exemplary embodiment, the airflow generated by the blowing device may be one or more of direct current wind, ion wind, hot air, and turbulence. In addition, the power and/or switch of the blowing device can be adjusted to adjust the size of the air flow out of the blowing port 3032 and/or start/stop the flow of the air flow.

The direct current wind may be, for example, an air flow generated by collecting compressed air by a wind generating device 3031 and then spraying it through a blowing port 3032. The air flow thus generated is guided between the current paper and the next paper as described above during the entire paging process, thereby improving the effect of paging.

However, the air flow blown out from the blowing port 3032 is not limited to the direct current wind, but may also be ion wind, hot air, turbulence, and the like.

For example, for paper with a film-coated material, a large amount of static electricity is generated during production and use, so that it is difficult to separate the current paper from the next paper due to the electrostatic force during the page turning process. In this case, by blowing the charged ion wind from the blowing port 3032, the charge on the paper can be neutralized, the electrostatic adsorption force can be reduced, and the page separation effect can be improved.

In this case, the air blowing device can use, for example, an ion wind rod, which can generate a large number of positive and negative charge air masses, and can neutralize the charge on the objects passing through the ion radiation area.

In addition, it may happen that books are wet due to high humidity in the air and rain. In this case, it is particularly useful to generate hot air from the blowing port 3032. On the one hand, it can dry the paper page by page, greatly improving the paper drying effect, and because the paper will be deformed due to heating during the drying process, which destroys the vacuum area between the current paper and the next paper , Which is more conducive to the effective separation between the two. The hot air can be realized by installing heating resistance wires in the wind generating device 3031, for example.

Although in the above description, the gas flowing out from the blowing port 3032 is described in the form of hot air, the present invention is not limited thereto. The gas flowing out from the blowing port 3032 may also be cold air or gas whose temperature can be changed or adjusted.

The turbulence causes the gas flowing out of the blowing port 3032 to be disturbed, thereby destroying the vacuum area formed between the current paper and the following paper. On the one hand, turbulence can be achieved by controlling the power of the wind generating device 3031, for example, to make its power randomly vary within a certain range. Alternatively, the turbulence can also be realized by moving the blowing port 3032 (for example, random swing) or the air flow guide (for example, random swing).

The ion wind, hot air and turbulence described above can further improve the separation effect of the paper.

In addition, according to an embodiment, the paging device may further include an ultraviolet lamp configured to emit ultraviolet light to the paper during the paging process, thereby achieving the effect of page-by-page disinfection. The ultraviolet lamp according to the present disclosure sterilizes the paper page by page by emitting ultraviolet light, so that the purpose of sterilization can be achieved more effectively.

Margin determination device

For the continuous paging process, the blowing port or the air guide part installed on the suction cup mounting part 3011 needs to be in a relatively fixed position relative to the current paper each time, so that the air current can be directed to the current paper at approximately the same angle and position And the next paper.

Therefore, in an 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.

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.

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.

After determining the distance of the suction cup 3022 relative to the edge of the paper, that is, the position and angle of the blower opening 3032 fixedly installed relative to the suction cup 3022 relative to the edge of the paper is determined, so that it can ensure that each sheet of paper can be roughly the same effect Implement paging.

In this exemplary embodiment, the margin determining device is configured such that the distance from the airflow generated by the blowing device to the edge of the paper is within a predetermined threshold, for example, 2cm, 1cm or other suitable values.

In addition, in the above description, one blowing port 3032 is taken as an example to describe the present invention, but the present invention is not limited to this. The blowing device according to the present invention may include multiple outlets, and the power and/or power of each outlet The switch is adjustable.

Specifically, as shown in FIG. 6, it shows a schematic diagram of the blowing port 3032 blowing toward the paper. As shown in the figure, two suction cups X1 and X2 are included on the paper, and multiple air outlets are shown as B1, B2, B3, B4, B5, and B6, where the air outlets B3 and B4 are exactly the same as the suction cups X1 and X2. The positions are relative, and B1, B2, B5, and B6 are relatively far away from the air outlet. In this case, due to the strong vacuum bonding force between the current paper and the next paper at the suction positions of the suction cups X1 and X2, the corresponding air outlets B3 and B4 are required to have greater power to destroy the current paper and The vacuum area between the latter sheets. On the contrary, at the position far from the suction cups X1 and X2, the vacuum suction force between the current paper and the next paper is relatively weak, and a relatively small applied power is required to achieve a better separation effect.

Based on this, in this exemplary embodiment, in order to reduce noise and improve the effect of paging, more power is applied to the air outlet of the suction cup along the edge of the paper, and less power is applied to the air outlet close to the suction cup. That is, as the distance from the suction cup in the paper edge direction increases, the power of the air outlet also increases. In this way, the separation of the current paper from the next paper can be achieved by gradually reducing the vacuum area from the periphery, which can better realize the separation of the paper compared with blowing directly against the vacuum area.

The distance of the air outlet from the suction cup in the direction of the paper edge may be predetermined, because the suction cup and the blowing port are relatively fixedly mounted on the suction cup mounting part. Alternatively, the relative position between the suction cup and the blowing port may be detected by a sensor or the like. By setting the power of the blowing port according to the relative position between the suction cup and the blowing port, the success rate of paging can be further improved while saving power.

Experimental verification

In this part, paging operations were performed 100 times on the same book under different circumstances, and the success rate of paging was counted. In the following description, the experimental conditions not specified in each case are the same as in case 1.

Case 1: The blowing and pressing device 1303 is vertically and fixedly installed on the frame (as shown in Figure 2), the air flow from the blowing port 3032 is direct current, the suction cups and blowing ports are arranged as shown in Figure 6, and each blowing The power of the mouth is the same;

Case 2: Hot air is blown out from the blowing port 3032;

Situation 3: Turbulent flow is blown from the blowing port 3032;

Case 4: The blowing device is installed on the suction cup mounting part 3011;

Case 5: The blowing device is installed on the suction cup mounting part 3011, and the power of each blowing port is different, the farther away from the suction cup, the lower the power;

Case 6: The blowing device is installed on the suction cup mounting part 3011, and the power of each blowing port is different, and the farther away from the suction cup, the greater the power.

Table 1 shows the data of the paging success rate under various experimental conditions:

Table 1

Situation 1	100	80	80%
Situation 2	100	86	86%
Situation 3	100	90	90%
Situation 4	100	96	96%
Situation 5	100	92	92%

As shown in Table 1, the blowing device is installed on the suction cup mounting part 3011 so that the blowing device follows the movement of the suction cup during the paging process, and then follows the movement of the current paper to blow air between the current paper and the next paper during the entire paging process. It can greatly improve the success rate of paper sorting, which has been increased from 80% to 96%.

In addition, turbulence and hot air flow can improve the success rate of paging to a certain extent, but turbulence is more conducive to the separation of paper than hot air flow.

In addition, compared to blowing against the suction cup installation position, applying more power to the blowing port at a position far from the suction cup installation position can improve the success rate of paging.

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.
