De 1. of the printing press body to show the arrangement of. ; They are a front view and a side view of the burr.

A stand 62 is provided for the delivery, which is suspended by a chain 6o. In the receiver, a pallet 64 and a board 66 are placed on a stand 62, and printed matter is stacked on the board 66. The chain 6o is moved up and down by a motor (not shown), and as the printed matter is stacked on the board 66, the tray 62 is lowered.

When a predetermined number of printed matter is stacked on the board 66, a new board Oat is inserted between the guide rails 88.7o to switch the board 66, and from then on, the printed matter is stacked on the board 66. are stacked on this new cutting board 661. The limit switch 16 is connected to this guide rail 68.
70, and turns on when a new cutting board 681 is inserted between the guide rails 68.7o.

Corner fittings 72 are placed at the four corners of the cutting board 66 on which printed materials have been stacked. After this, the stand 62 of the receiver is slightly raised and the corner metal fitting 72 is moved to the new cutting board 8B.
+, the guide rails 68, 70 are moved as shown by the broken lines in the figure, and a new cutting board 68i is moved.
is placed on the corner fitting 72.

When a predetermined number of printed materials are stacked on the pallet 64, the cutting board 8B is lowered to the lowest end of the delivery system for replacement of the pallet 64. A limit switch 18 is provided at the lowest end of this delivery, and the receiver is turned on when the platform 62 is lowered to the lowest end. When replacing the pallet, first, a new cutting board 6Bj is inserted between the guide rails 68 and 70. Then, the tray 62 is lowered to the lowest end, the pallet B4 on which the printed matter is stacked is carried out from the tray 62, and a new pallet is placed on the tray 62 in its place.

After this, when the platform 62 of the receiver is raised and the new pallet comes to support the new board 66I, the guide rail B8.70 is moved as shown by the broken line in the figure, and the new board 061 is moved. is placed on a new pallet.

Changing the cutting board and replacing the pallet may be done while the printing press is in operation or not.

Next, the operation recording operation of the printing press according to this embodiment will be explained.

First, in this embodiment, the status signal generated by signal generator 12 is latched into input buffer 46, 48 via relay 20. The number of printed matter is counted by supplying a signal from the printed matter passage detection sensor I4 to the counter IC50. Manual buffer 4G, 48, counter IC
50 data is periodically read by the MPU 30, and the read latch signal is cleared each time. This is performed by an interrupt from the read timer, and its cycle is approximately tssec - Lsec.

The read signal is stored in memory 3B. Each read signal is compared with the previously read signal, and only for signals that have changed, the signal and the time of change are recorded (displayed on the display). Signals that repeatedly turn on and off during the reading period are ignored because they are short-term changes.

An example of the display on the display 38 is shown in FIG.

For work that cannot be determined by only the signals from the signal generator 12, such as "starting", "1st movement", "stop", etc. related to the movement of the printing press, there is a selection display column showing various work contents as examples. 82 is entered manually at the position of the cursor 80 using the numeric keys of the keyboard 40 to confirm the work contents. This manual work is performed only on work that is important in terms of information, and the work is finalized before one pallet is delivered.

Time 84 is the time at which the corresponding signal is generated.

After one pallet is carried out, the printer 44 outputs a quality record for the pile of printed matter on one pallet. Fourth
The figure shows MPU3 when outputting this quality record from a printer.
0 is a flowchart. When the operation starts, it is determined in step s1 whether the printing press is in operation. Whether the printing press is in operation is determined by whether the signal generator 12 outputs a signal related to the rotation of the machine such as "1 movement, slow movement, low speed, high speed". If the printing press is in operation, it is determined in step S2 whether the limit switch 1B is on. The limit switch 16 is turned on when a new cutting board is inserted into the guide rail to change the cutting board. When it is detected that the limit switch 16 is turned on, the current time counted by the timer 34 is stored in the register X, and the count value of the counter IC 50 (total number of printed matter) is stored in the register Y.

If the limit switch 1G is off, step s1 is executed again.

In step S4 following step S3, it is determined whether the limit switch 18 is on. limit switch 18
is turned on because the pallet 64 is replaced.
2 is lowered to the bottom of the delivery. If the limit switch 18 is off, it is determined again in step S5 whether the limit switch 16 is on. If the limit switch 16 is on in step S5, step S1 is executed again. If the limit switch 16 is off in step S5, step S4 is executed again.

If it is determined in step S4 that the limit switch 18 is on, it is time to replace the pallet, so in step S6 the data in register
Let the data be the number of pallets replaced. The number of pallet exchanged sheets indicates the total number of printed matter at the time of pallet exchange, that is, what number of printed matter was printed when the pallet was exchanged.

On the other hand, if it is determined in step S1 that the printing press is not in operation, it is determined in step S7 whether the limit switch 18 is on. If the limit switch 18 is off, step S1 is executed again. When it is detected that the limit switch 18 is turned on, the current time counted by the timer 34 is determined to be the pallet exchange time and the counter IC at step S8.
The count value of 50 is the number of pallets to be replaced.

As described above, in this embodiment, when replacing the pallet while the printing press is in operation, the board for removing the board is inserted and then the tray 62 is lowered to the lowest end of the delivery, so the board for removing the board is not inserted. The current time of the timer 34 and the count value of the counter IC 50 at the time of delivery are stored in registers The pallet exchange time and the number of pallets exchanged are used. As a result, the number of printed materials that are stacked on the new board after the board is inserted and the pallet table descends to the lowest point of delivery will not be included in the number of sheets to be replaced on the pallet. , the number of printed sheets on one pallet is accurately calculated. In addition, when replacing the pallet while the printing press is not in operation, the tray 62 is lowered to the lowest delivery end without inserting the plate receiving plate, so that the timer 34 when the plate receiving plate is inserted is The current time and the counter IC 50 are taken as the pallet exchange time and the number of pallets exchanged.

When the pallet exchange time and the number of pallets to be exchanged are set in steps S6 and S8, in step S9, the number of pallets to be carried out is determined based on the difference between the number of pallets to be exchanged at the previous pallet exchange time and the number of pallets to be exchanged at the current pallet exchange time. The number of prints stacked on one pallet is calculated. Here, the defective printed matter is actually removed by the operator when it is output from the printing machine to the delivery machine.
The number of defective printed matter sampled by the operator is counted and input from the keyboard 40, and this number of sampled sheets is subtracted from the calculation result.

Thereafter, a quality record is printed out from the printer 44 in step SIO.

FIG. 5 shows an example of output from the printer 44. For example, the printing on the first line indicates that the ink key was operated at 8:25, and specifically, the 28th ink key of the third color cylinder is moved in the width direction -1, and the 26th ink key is operated. Indicates that it has been moved by +5 in the width direction. Furthermore, the print on the fourth line indicates that the 26th to 28th ink keys of the third color cylinder were cleaned of dust at 11:11.

As explained above, according to this embodiment, a signal indicating the quality of the printed matter being printed is input while the printing press is in operation, and the change status is displayed on the display, and a pile of printed matter is displayed on the pallet. The printer outputs a quality record summarizing the quality of each pile of printed matter each time it is stacked, so the printer's operation recording device makes it easy to control the quality of each printed matter on the pallet that is taken out from delivery. Realized. Here, the timing of the limit switch 16 is adjusted when the printing press is in operation, and the timing of the limit switch 18 is adjusted when the printing press is not in operation.
Since the timing is set as the pallet exchange timing, it is possible to prevent the number of printed matter on the pallet from being inaccurately counted due to a deviation in the insertion of the cutting board at the time of changeover.

Note that the present invention is not limited to the embodiments described above, and can be modified in various ways, and details such as the print quality to be recorded can be changed.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide a printed matter performance recording device that can record the quality of printed matter.
