[0063] The turning unit box 12 of the bidirectional rotating conveying mechanism 1 and the certificate self-service storing and taking equipment of the utility model, after receiving the certificate vertically, first, the second rotating motor 132 acts, drives the turning unit box 12 to rotate around the vertical direction 90 DEG, in this action process, the certificate rotates around the vertical direction 90 DEG in the vertical posture, that is, changes from Figure 2 to Figure 3 Then, the first rotating motor 131 acts, drives the turning unit box 12 to rotate around the longitudinal direction 90 DEG, in this action process, the certificate rotates around the longitudinal direction 90 DEG, changes from vertical to horizontal, that is, changes from Figure 3 to Figure 4 So that one end of the certificate is opposite the entrance of the text module 4. Of course, the first rotating motor 131 can act first, drives the turning unit box 12 to rotate around the transverse direction 90 DEG, in this action process, the certificate rotates around the transverse direction 90 DEG, changes from vertical to horizontal, then the second rotating motor 132 acts, drives the turning unit box 12 to rotate around the vertical direction 90 DEG, in this action process, the certificate rotates around the vertical direction 90 DEG in the horizontal posture. When the certificate is a passport, the bidirectional rotating conveying mechanism 1 and the certificate self-service storing and taking equipment of the utility model can realize the bidirectional turning conveying of the passport, to convey one end of the passport to the entrance of the text module 4.

[0064] Please refer to Figure 2 and Figure 11 One side of the turning unit box 12 is connected with the rotating power source 13, and the opposite side of the turning unit box 12 is provided with an insertion opening 121 for inserting the certificate into the turning unit box 12. By adopting the above structure, the turning unit box 12 is convenient for receiving the certificate.

[0065] Please refer to Figure 4 and Figure 11The opposite ends of the turnover unit box 12 are provided with openings 122, and the insertion opening 121 is located between the two openings 122. The bidirectional rotating conveying mechanism 1 further comprises a pushing mechanism 14, which comprises a pushing rod 141 and a pushing driving assembly 142. The pushing rod 141 is arranged to move in the transverse direction. When the turnover unit box 12 is in a horizontal posture, the pushing rod 141 can extend into one of the openings 122 and push the passport out of the other opening 122, so that the passport is located in the text module 4.

When the turnover unit box 12 is in a horizontal posture, the bearing 126 of the movable baffle 123 away from the push rod 141 abuts against the limiting block 15, so as to push the connecting rod 125 and the corresponding movable baffle 123 to rotate, so as to open the movable baffle 123. When the turnover unit box 12 is in a vertical posture, the bearing 126 on the movable baffle 123 is not subjected to external force, and the movable baffle 123 is automatically closed by the action of the torsional spring 124. When the turnover unit box 12 is rotated to a horizontal posture, the bearing 126 of the movable baffle 123 away from the push rod 141 abuts against the limiting block 15, and the limiting block 15 applies external force to the bearing 126, so that the movable baffle 123 is rotated and opened. By adopting the above structure, the movable baffle 123 away from the push rod 141 can be automatically opened, and the passport can be conveniently taken out of the turnover unit box 12. In other embodiments, the second rotating motor 132 can be arranged on the first rotating motor 131, and the first rotating motor 131 drives the second rotating motor 132 to rotate. The position of the limiting block 15 can be flexibly arranged, such as on the rack 11.

[0069] The turnover unit box 12 is provided with a shooting port 127 for exposing the certificate. The bidirectional rotating conveying mechanism 1 further comprises a photographing mechanism 17 arranged on the rack 11. When the turnover unit box 12 is in a horizontal posture, the photographing mechanism 17 is located above the shooting port 127 and is used for photographing the certificate.

Taking the passport as an example, the photographing mechanism 17 photographs the passport in the turnover unit box 12 through the shooting port 127. If the photographing mechanism 17 does not photograph the cover of the passport, the first rotating motor 131 drives the turnover unit box 12 to rotate by 180°. If the photographing mechanism 17 photographs the cover of the passport, the first rotating motor 131 does not need to act. Through the cooperation of the photographing mechanism 17 and the first rotating motor 131, the cover of the passport can be placed upwards when the passport is located in the text module 4, so as to meet the requirements.

[0070] Please refer to Figure 6 , Figure 7 , Figure 8 and Figure 11The two sides of the turnover unit box 12 are provided with a shooting port 127, and the two shooting ports 127 are in communication with the insertion port 121. The bidirectional rotating conveying mechanism 1 further comprises a guide mechanism 16, and the guide mechanism 16 comprises a guide block 161 and a guide driving element 162. The guide block 161 is movably arranged. The guide driving element 162 is arranged on the rack 11 and is connected to the guide block 161, and is used for driving the guide block 161 to move, so that the guide block 161 abuts against the passport, and then the position of the passport in the turnover unit box 12 is corrected. The guide block 161 is close to the turnover unit box 12 and abuts against the passport, so that the passport does not deviate when leaving the turnover unit box 12, and is smoothly pushed out. In the embodiment, the guide block 161 is movably arranged in the longitudinal direction, and when the turnover unit box 12 is in a horizontal posture, the guide block 161 is located on the longitudinal side of the insertion port 121, and the guide driving element 162 is used for driving the guide block 161 to move in the longitudinal direction, so that the guide block 161 abuts against the passport. In other embodiments, the position of the guide block 161 can be adjusted, and the direction in which the guide driving element 162 drives the guide block 161 to move also needs to be adjusted.

[0071] Please refer to Figure 13 The guide block 161 is provided with a limiting groove 1611, three sides of the limiting groove 1611 are open, and the limiting groove 1611 is used for accommodating the edge of the passport. By limiting the passport through the limiting groove 1611, when the passport is corrected, the passport can be prevented from being displaced in the vertical direction, so that the passport can be more smoothly pushed out.

[0072] The working principle of the passport self-service storage and taking equipment in the preferred embodiment of the utility model:

[0073] The longitudinal moving trolley 51 conveys the passport on the base library 3 in the longitudinal direction to the vertical moving trolley 52, and the vertical moving trolley 52 conveys the passport in the vertical direction. The passport is conveyed into the vertical turnover unit box 12 through the insertion port 121.

[0074] After the turnover unit box 12 receives the passport in the vertical posture, first, the second rotating motor 132 acts to drive the turnover unit box 12 to rotate 90° around the vertical direction, and in this action process, the passport rotates 90° around the vertical direction in the vertical posture, then the first rotating motor 131 acts to drive the turnover unit box 12 to rotate 90° around the longitudinal direction, and in this action process, the passport rotates 90° around the longitudinal direction, and changes from the vertical posture to the horizontal posture, so that one end of the passport faces the entrance of the text extraction module 4.

[0075] When the turnover unit box 12 is in the vertical posture, the bearing 126 on the movable baffle 123 is not subjected to external force, and the movable baffle 123 is automatically closed by the action of the torsional spring 124. When the turnover unit box 12 rotates to the horizontal posture, the bearing 126 of the movable baffle 123 away from the passport pushing rod 141 is in contact with the limiting block 15, the limiting block 15 applies external force to the bearing 126, so that the movable baffle 123 rotates to be opened.

[0076] The photographing mechanism 17 photographs the passport in the turnover unit box 12 through the photographing port 127, and if the photographing mechanism 17 photographs the cover of the passport, the first rotating motor 131 drives the turnover unit box 12 to rotate 180°. If the photographing mechanism 17 photographs the cover of the passport, the first rotating motor 131 does not need to act.

[0077] The guide block 161 is close to the turnover unit box 12 and abuts against the passport. The push base rod 141 acts and is inserted into the turnover unit box 12 through the avoiding hole 1231, pushes the passport in the turnover unit box 12, and the pushed passport enters the passport text module.

[0078] The above is the working principle of the certificate self-service access equipment of the preferred embodiment.

[0079] The bidirectional rotating conveying mechanism and the certificate self-service access equipment, the turnover unit box is received to the passport in the vertical posture, first, the second rotating motor acts to drive the turnover unit box to rotate 90° around the vertical direction, in the action process, the passport rotates 90° around the vertical direction in the vertical posture, then the first rotating motor acts to drive the turnover unit box to rotate 90° around the longitudinal direction, in the action process, the passport rotates 90° around the longitudinal direction and changes from the vertical posture to the horizontal posture, so that one end of the passport faces the entrance of the passport text module. Of course, the first rotating motor can act first to drive the turnover unit box to rotate 90° around the horizontal direction, in the action process, the passport rotates 90° around the horizontal direction and changes from the vertical posture to the horizontal posture, then the second rotating motor acts to drive the turnover unit box to rotate 90° around the vertical direction, in the action process, the passport rotates 90° around the vertical direction in the horizontal posture. The bidirectional rotating conveying mechanism and the certificate self-service access equipment can realize the bidirectional rotation and conveying of the passport, so that one end of the passport is conveyed to the entrance of the passport text module.

[0080] In conclusion, although the utility model has disclosed the above-mentioned preferred embodiment, the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
