2. Description of the Related Art In a conventional printing machine or copying machine, a sheet conveying means for printing sheets is provided inside the printing machine or copying machine. FIG. 14 is an external view of a printing apparatus showing a conventional technique. That is, as shown in FIG. 14, the paper supply is performed by pulling out the tray 101 housed in the printing apparatus 100, housing a predetermined amount of paper in the tray 101, and then housing the tray 101 in the printing apparatus 100. Was done manually. On the other hand, the printed sheets are sequentially discharged onto the mounting plate 102 provided in the printing apparatus 100. The discharged sheets are sequentially conveyed by hand.

In such a printing apparatus, the number of sheets that can be stored in the tray and the number of sheets that can be discharged to the mounting plate can be set to several thousands on the tray 101 or the mounting plate 102 for high speed and large volume. The print processing time for this number of sheets is about 20 to 30 minutes. Further, in supplementing the paper, it is necessary to interrupt the printing state, pull out the tray again, and store a predetermined amount of paper in the tray 101. Then, it is necessary to restore the printing apparatus 100 to the printing state again.

As described above, particularly in high-speed and large-volume printing processing, when the processing time for printing alone requires, for example, 12 hours, paper replenishment is required about 30 times, and this time loss is large. Further, it is necessary for a person to always carry the paper discharged from the printing apparatus to a predetermined place. Therefore, as a means for performing a large amount of printing processing in a short time, means for performing night driving can be considered.

In FIG. 6B, when the printed sheets are stored in the stocker 55, the sheets are sequentially stored in the stocker 55 which has finished supplying the sheets to the tray 41.
At this time, the sheet conveyance control unit 60 controls so that the sheets are stored for each print type. Since the sheets are stored according to the print type, there are places where the stocker 55 does not correspond to the divided sheet storage capacity. In this case, increase the paper storage capacity of the stocker 55 sorted in advance, or do not set the paper before printing on the stocker 55.
This is dealt with by providing.

Next, details of the paper supply unit of the printing unit will be described. FIG. 8 is a schematic diagram of the paper supply unit according to the first embodiment of the present invention. In the figure, the printing unit 40 is provided with four trays 41a to 41d. The trays 41a and 41b are used as the sheet conveying means (1) 56a shown in FIG. 4, and the trays 41c and 41d are used as the sheet conveying means (2) 56b. When a paper replenishment or a paper jam occurs, the operation of the paper transportation from the tray 41a and the tray 41b, and the paper transportation from the tray 41c and the tray 41d is switched in the paper transportation control unit 60 in response to the notification from the detection means 61. Control to continue automatically.

When replenishing the sheet, for example, when the tray 41a that is empty of the sheet is detected, the operation of the sheet conveying mechanism (not shown) of the tray 41a is stopped and the operation of the sheet conveying mechanism of the alternative tray 41b that stores the sheet is performed. To start.
Then, the series of operations from step S13 to step S18 in FIG. 6 described above is performed to complete the paper supply.

A rotation fulcrum portion 73 for finely adjusting the direction of the arm 76 and a rotation fulcrum portion 74 for opening and closing the robot arm 76a so that the robot arm 76a can move on the paper when holding the paper are provided. The rotation fulcrum portion 72 may be provided so as to rotate the vertical movement mechanism portion 77.

The operation of the robot arm 76 will be described with reference to FIG. A indicates the position when holding the unprinted paper stored in the stocker 55 or the position when the printed paper is stored in the stocker, and B indicates the tray 41.
2 shows the position when the paper is stored, and C shows the position when the printed paper stacked on the mounting plate 42 is held. The vertical movement mechanism section 77 is regulated by the sheet conveyance control section 60 to a height corresponding to each of the stocker 55, the tray 41, and the mounting plate 42.

Next, details of paper discharge will be described.
FIG. 13 is an explanatory diagram of paper ejection according to the first embodiment of the present invention.
In FIG. 9A, a paper table 90 is provided on the top of the mounting plate 42 via a rotation mechanism section 92. The paper tray 90 is provided with a paper guide 91 that regulates the position of the printed paper 93 discharged from the printing unit 40. The rotation mechanism section 92 changes the stacking direction of the printed paper 93 each time a part of the printed paper 93 is stacked on the mounting plate 42 so that the printed paper 93 can be sorted for each part. Is.

FIG. 13B is a schematic diagram of the sheet discharge to the sheet tray 90. In the figure, the first printed sheet 93
After "a" is loaded on the paper table 90, the paper table 90 is rotated clockwise by 90 degrees by the rotation mechanism section 92. Then, the second printed sheet 93b to be ejected next is stacked and then returned to the original position by the rotation mechanism section 92. By repeating this operation in sequence, it is possible to sort the printed paper 93 for each part. It should be noted that by setting the operation timing of the rotation mechanism section 92 in a timely manner, the rotation mechanism section 92 can be divided into predetermined copies. Further, the rotation mechanism section 92 may be provided in the printing section 40.

The embodiments of the present invention have been described above.
The present invention is not limited to this embodiment. For example, the paper is supplied to the tray only without using the paper tray. The print processing unit and the bookbinding processing unit are also duplicated. The stocker group and the paper transport robot should be a slide movement mechanism instead of a rotation movement mechanism. The present invention can also be applied to a document supply type printing device that does not store print data, or an integrated type printing device in which a stocker group or a paper transport robot is provided in the printing unit.
