Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing press management device that manages the production status of a printing press.

Conventionally, as a system for managing the production status of printing presses, there has been a system that connects a tachometer to the main motor and records the operating and stopping status of the printing press.
This system handles only a small amount of information and does not monitor recorded information in real time.
It was not possible to adjust the operation of the printing press according to the production situation.

This invention has been made to address the above-mentioned circumstances, and provides a printing press management device that processes various information regarding printing presses online and in real time, and enables the printing press to be operated according to the production status. is its purpose.

Hereinafter, an embodiment of a printing press management apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of this embodiment. This device is
A CPU 10, an interface 11, and a magnetic card reader/writer 12 that receive and process signals from various sensors installed in the printing press.
, keyboard 14, and CRT display 16
, a floppy disk unit 18, a printer 20, etc. Although the type of printing press to be managed by this apparatus is not limited, as an example, the flow of data when connected to an offset rotary press will be explained with reference to the block diagram shown in FIG.
The CPU 10 has a sensor group 22 connected to the printing machine.
A signal indicating the operating status of each part of the printing press is supplied from the printer via a totalizing circuit 24 and an integrating circuit 26. The CPU 10 also has a calendar clock generator 28.
Also supplied are signals from In Figure 2, the first
Elements corresponding to those in the figure are given the same reference numerals as in FIG. 1, and their explanation will be omitted. The worker first inputs the work rod from the keyboard 14. This input may be performed using the magnetic card reader/writer 12. This work rod is information that is known in advance, such as the name of the work item, the lot amount, and the reserve margin. When the printing press starts operating, the CPU 10 enters a production status processing mode, and displays the current production status on the CRT display 16 based on input signals from the sensor group 22. Here, the sensor input signals include a rotation synchronization pulse of a printing press, a cylinder attachment/detachment signal, a swimmer attachment/detachment signal, an ink attachment/detachment signal, and the like. This results in
The production status of the printing press, ie, the number of good sheets printed, the number of waste sheets printed, the target production number, etc., is displayed online in real time, and the operator can adjust the rotation of the printing press according to this display.

Next, when a printing press stop signal and an autopaser signal are input, the CPU 10 enters the paper use mode. Here, the reason for the stop and the reason for wasted paper are input from the keyboard 14. The CPU 10 detects the passage of time based on the signal from the calendar clock generator 28, and causes the CRT display 16 to display the paper usage status and machine stop status for each paper roll.

When the work is completed, the CPU 10 shifts to the aggregation mode and displays the production status for each work lot or worker.
Calculates (displays and prints out) paper usage status. In this case, usage of resources such as water, gas, electricity, ink, etc. may also be totaled.

An example of the sensor group 22 is shown in FIG. This example shows a circuit for distinguishing between genuine and waste paper. AND gate 3 conducts only when paper feeding is normal
2 is supplied with a rotational pulse representing the rotational speed of the printing press. The output signal of the AND gate 32 is connected to the first input terminal of the AND gates 34 and 36 and to the total number counter 3.
8. AND gate 40 to which a discrimination signal is supplied and rendered non-conductive by a signal representing waste paper;
An output terminal of is connected to a second input terminal of AND gate 34 and an input terminal of inverter 42 . An output terminal of inverter 42 is connected to a second input terminal of AND gate 36. The output signals of the AND gates 34 and 36 are supplied to a correct paper counter 44 and a waste paper counter 46, respectively. Here, the discrimination signals include a signal indicating that swimmer loading/unloading, body loading/unloading, and ink loading/unloading are performed normally, a signal indicating that the dryer is operating at an appropriate temperature, folding machine tension, cut-off range, and edge guide range. A signal indicating that the paper is appropriate, a signal supplied from the keyboard when waste paper occurs, etc. are used. As a result, the total number of sheets is counted by the counter 38 according to the rotation of the rotary machine, and if there is no reason for wasted paper,
When the AND gate 40 becomes conductive, the correct paper sheet number counter 44 is operated, and if there is even one reason for wasted paper, the AND gate 40 becomes non-conductive and the waste paper sheet number counter 46 is operated.

As described above, according to this embodiment, since it is possible to perform aggregation for each good paper and waste paper, and to aggregate and manage resources, it is possible to improve the operating efficiency of the printing press and to save energy.

Note that the present invention is not limited to the embodiments described above, and the location where the sensor is installed can be changed as appropriate depending on the type of printing press and the object of management. Furthermore, by connecting several printing presses to one management device, overall management such as work distribution is possible.
