Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to parts that will be consumed in maintenance of a printing press, such that the inspection time and replacement time can be determined in advance based on the expected life of the parts and the cumulative operation of the printing press. The present invention relates to a printing press maintenance management system configured to calculate, print out on a display or a list, set an ordering point for parts, and place an order for parts.

[Conventional technology]

Since the number of consumable parts of a rotary printing press is very large and it is composed of various parts, the management of parts is extremely complicated. In addition, newspaper production must be intensively produced in a short time, so maintenance and management of rotary printing presses is one of the most important things. The current situation is that a lot of work must be done to maintain these.

[Problems to be solved by the invention]

The "Newspaper Printing / Shipment Automation System" completed at the Osaki Plant (Chiyoda Sogyo) of Nihon Keizai Shimbun in 1973 is an NPC system (Newspaper Plant Computerized Sy) that is a system that controls the process from printing to shipping by computer.
stem), the automation of the system is from "line" to "face"
In recent years, a total systemization is being considered for "three-dimensional".

The total system as described above includes a group of high-speed real-time processing units such as a rotary printing press management unit, a plate transport management unit, a shipping sorting management unit, a truck yard bundle integration management unit, a paper stock management unit, and a shipping material supply management. Departments, etc., comparatively low-speed processing group, materials and maintenance management department, so-called offline processing-capable group, commanding information processing group such as sales quantity increase / decrease management unit, high-speed real-time processing required group, relatively low-speed processing The production process management department that manages the possible group etc.
Either the processor or the intelligent input / output control device executes each given individual process.

In order to complete the above total system, it is essential to incorporate the maintenance management system into the total system.

[Means for solving problems]

The present invention is intended to solve the above-mentioned problems, and includes a start and stop signal of a rotary press, a rotation pulse signal of a main shaft, a rotation pulse signal of a brush roller, a paster operation signal, an ON / OFF signal of a slitter, and a dampening water. The PH detection signal etc. is taken into the computer, the operating time, the number of times of operation, and the total of the number of prints are accumulated, and the total is subtracted from the predicted life (represented by time, the number of times of operation, the number of prints) that has been input in advance. ，
The remaining service life is calculated, and the remaining service life is divided from the average daily operating time, number of operations, and the number of printed copies, so that the number of durable days of the component can be known and the replacement date of the component can be calculated.

The schedule of the inspection work is to input into the computer the importance of each part and the frequency of operation, frequency rate, and strength rate based on statistical data. Output and reference.

FIG. 1 shows the principle configuration of the present invention. In the figure, reference numeral 1 is a production process management unit, which manages the entire total system.
A rotary printing press management unit 2 controls and manages the operation status of the rotary printing press. 100 represents a rotary printing press. The present invention is directly related to the illustrated material and maintenance management unit 8, 201 is a maintenance management processor, 202 is a display, 203 is a printer, and 204 is a disk memory, which is information relating to material management and maintenance management. Stored in, 2
05 represents the interface part.

The life of materials and parts used for printing is generally expressed as a function of the number of copies printed, expressed as a function of the number of prints, expressed as a function of the printing press operating time, or the number of copies printed. , A number of times of printing, and a function expressed as a composite of 2 to 3 of the printing press operating time. Therefore, the information necessary for predicting the life is supplied from the rotary printing press 100 or the rotary printing press management unit 2 and managed by the maintenance management processor 201.

[Action]

From the rotary printing press management unit 2, a reset signal, a start signal, a stop signal, a spindle rotation pulse signal regarding the rotary printing press 100,
Brush roller rotation pulse signal, paster signal, slitter
ON / OFF signal, PH detection signal, etc. are supplied. These signals have different operation timings and operation times of corresponding parts depending on the operation sequence of the rotary printing press 100.

Alternatively, a warning is output to the display 202 or the printer 203 so that the maintenance can be performed in advance. For example, if the bearing temperature of the cylinder can be detected in advance, it will be possible to avoid a bearing burning accident and repair it during normal maintenance work.

From the production process control section 1 shown, the printing unit number used,
Cylinder of the printing unit used, plate mounting position data, folder number, slitter number used, compensator roll number used, cutoff roll number used, etc. are coded and transmitted to the processor 201 for maintenance management. To be done. These pieces of information are used as building pages and as data for selecting parts to be used and parts not to be used by threading the paper. In the figure, one set of rotary printing press 100
However, it is needless to say that the interface unit 205 shown in the figure is added in proportion to the number of sets, since a rotary printing machine of several sets to several sets is generally used.
