Referring to fig. 1-15, the working principle of the electronic document issuing machine in this embodiment is:
generally, the certificate is opened first to expose the page printed with the relevant identification information, then the certificate is placed in the discharge hopper 1b, one end face of the certificate is attached to the conveying belt 3b, the other end face of the certificate is abutted against the material supporting plate 1-2b, and then the conveying belt 3b drives the certificate to move towards the detection module through the discharge hole 4b under the driving of the feeding driving motor 2 b. When a plurality of certificates are stored in the discharge hopper 1b, the conveyor belt 3b firstly conveys out the certificate which is positioned at the lowest position and is stuck on the conveyor belt 3b under the drive of the feeding drive motor 2b, so that the certificate which is originally positioned at the lowest penultimate is dropped on the conveyor belt 3b, and then the conveyor belt 3b conveys out the certificate which is originally positioned at the lowest penultimate, so that the certificates are sequentially conveyed out from the discharge hopper 1b from bottom to top.
After the certificate is transferred from the discharging hopper, the X-direction conveying mechanism 3c conveys the certificate to the detecting station 5c for detection. After the detection is finished, the certificate is conveyed to a corresponding collecting box; for example, when the content displayed on the certificate corresponds to the content recorded on the chip after the detection is completed, the X-direction conveying mechanism 3c is considered to be in agreement with the information, and conveys the certificate from the detection station 5c to the first collection box 1c; when the content displayed on the certificate does not correspond to the content recorded on the chip, the Y-direction conveying mechanism 4c conveys the certificate from the superimposition area to the second collection box 2c, regarding that the information does not match.
The process of the Y-direction conveying mechanism 4c conveying the certificate from the detection station 5c to the second collecting box 2c is that the avoidance part 4-11c is arranged on the driving wheel 4-1c, so that the certificate does not interfere with the driving wheel 4-1c positioned in the X conveying channel when conveyed to the detection station 5c, but passes through a gap between the avoidance part 4-11c and the driven wheel 4-2 c; when the information of the certificates is inconsistent, the roller driving mechanism drives the driving wheel 4-1c to rotate, the avoiding part 4-11c starts to rotate, so that the rim part on the driving wheel 4-1c acts on the certificates, and the certificates are driven towards the second collection box 2 c. Therefore, the conveying roller in the X conveying channel can not obstruct the conveying of the certificate in the X conveying channel, can convey the certificate to the Y conveying channel, has compact and ingenious structure, and can reduce the volume of the equipment.
The foregoing is illustrative of the present invention, and is not to be construed as limiting thereof, but rather as various changes, modifications, substitutions, combinations, and simplifications which may be made without departing from the spirit and principles of the invention are intended to be included within the scope of the invention.
