As shown in fig. 2, it is a three-coordinate conveying device part, which includes two L-shaped asymmetric angle aluminum supports 13, an L-shaped doctor blade 14 mounted on a hard synchronous belt, a driving synchronous belt gear 15, an edge turning passive synchronous belt gear 16, a hard open synchronous belt 17, and two middle turning passive synchronous smooth wheels 18; the distance between the flanges of the two L-shaped asymmetric angle aluminum brackets 13 is about 10mm more than the length of the long edge of A4 paper, so that the L-shaped doctor blade is prevented from being clamped due to too small distance between the edges in the paper transportation process to cause the paper to tilt, and the supporting edges of the angle aluminum brackets 13 are adhered with glass to reduce the resistance in the paper transportation process; the synchronous belt is made of a harder hard rubber material so as to prevent the L-shaped scraper 14 arranged on the hard synchronous belt from toppling when pushing paper; the distance between the driven synchronous smooth surface wheels 18 for the two turns in the middle part is smaller than the radius of the driving synchronous belt gear 15 so as to increase the wrap angle and prevent the phenomena of tooth climbing and slipping when paper is conveyed.

As shown in fig. 3, the part of the rotary tray butt-joint device of the printer comprises a stepping motor 19 with a worm gear box, two support rods 20, two channel aluminum installation flange brackets 21, a support rod connecting block 22 and a cylindrical through hole coupler 23; it should be noted that, because the length of the long edge of the A3 paper is large, when the paper exceeds a certain number, because the center of gravity of the A3 paper is behind, the support rod of the rotating tray needs a large locking force to be balanced, and in consideration of the problem of limited installation space, the step motor with the turbine worm box is adopted, so that the installation space can be saved, self-locking is realized, and the problem of insufficient locking torque of a common step motor is also solved; adopt cylindrical through-hole shaft coupling 23 couples together drive shaft and output polished rod, adjusts the locking force through the housing screw, can avoid when automatic conveying device trouble, if the platform interferes with rotatory tray, the rotatory tray that is connected with the printer body damages, because transshipping this moment can make shaft coupling and polished rod coupling part idle running skid to protected tray and printing all-in-one body can not damaged by external force.

As shown in fig. 4, a three-coordinate based print job automated storage and pickup system includes the following steps:

1) a user issues a printing task through desktop printing software installed in each work computer, when the user clicks a button for submitting any printing, system software automatically detects whether an empty box body is available in a storage cabinet, if the empty box body is not available, the printing user is informed of the fact that no available box body exists, the corresponding user is informed of taking a piece in time, and a system maintenance manager is informed of cleaning the box in time;

2) if the box body is available, the printing operation submitted by the user is sent to a server directly connected with the printer for scheduling, the server is provided with a printer matching driver, and a whole set of software for transportation interaction and printing task queue scheduling of the automatic conveying platform is arranged. The printing operation is inserted into a database and a printer queue according to the priority, when the printer is idle, software firstly detects whether each state of the printer is normal, such as whether paper is sufficient or not, whether paper is available or not, whether an ink box of the printer is available or not, whether the in-place state of the printer is normal or not, whether other alarm faults such as paper jam and the like occur or not, if no fault exists, the operation is scheduled according to the printing queue for printing, if the fault exists, relevant fields of the database are marked, alarm information is thrown out, an administrator is informed to carry out treatment in the future, and the user is informed of printing failure;

3) the printer prints the job submitted by the user smoothly, and at the moment, the job paper is prepared and put in order on the printer rotating tray. At the moment, the software judges whether the platform is ready, if the platform is ready, the software issues a command of transporting the printing paper to a specified box, and the automatic conveying system starts to send the printing paper to the box for storage;

4) if the paper is conveyed into the box completely normally in the step 3, and at the moment, the designated mark field of the database is set to be three-coordinate transportation completion, the software sends a pickup code and a two-dimensional code through the WeChat platform to prompt a user to pick up the paper in time;

5) after the user receives the pickup code, the user should go to the storage cabinet to pick up the piece within 24 hours in time, the system is provided with two modes of inputting the pickup code type pickup and scanning the code two-dimensional code pickup, and the user can select the pickup mode by himself. When the user finishes taking the file, the file taking box is closed, the file taking record of the database is eliminated at the moment, and meanwhile, a historical data record is inserted, so that tracking statistics are facilitated.
