The present invention relates to a method of counting and printing ink using offset printing machines and a production management system using the same. More specifically, the number of printed matters, the number of genuine printed matters, and the wastes are reduced by using a sample balance, a main scale, and a sensor. It is possible to calculate the number of copies, and to check the amount of ink used in each work unit in real time, and the counting data and ink consumption data of the measured materials as described above are recorded, statistics, and reported through the control unit to implement automation of production management. It is about the management system of the rotary press.

A rotary press is a method of printing a sheet of paper between a printing unit consisting of a plate and a blanket, and a printing sheet passes through the printing unit, and a printing plate is mainly composed of a flat plate method.

The paper used in the offset rotary press is a rolled paper (winding paper), most of which is equipped with a folding machine folding paper at the rear of the rotary press line, and is normally folded and discharged into 16 sections. Such an offset rotary press is used for high-speed printing of about 60,000 million revolutions per hour. Because it is a machine, it is used for many copies of printing, such as newspapers, magazines, weekly, textbooks, and telephone books.

All of the offset rotary presses are premised on both sides printing and printing from one color on both sides to as many as six colors on both sides. In addition, since the grounding work is performed immediately after printing, the ink uses fast-drying ink when there is no dryer and heat-drying ink when there is a dryer.

However, due to the high speed of the printing press, the initial printing amount of the offset printing press typically reaches 3,000 to 5,000 sheets, but the exact number of used sheets is not yet known. No attempt was made to calculate the extension length of the roll paper, nor was accurate counting of net prints.

In addition, in recent years, the use of ink has been increasing with the advancement of printed materials, but there is no way to accurately determine the ink usage by unit of work. It was impossible.

Therefore, due to the inaccurate print count value and lack of data on ink usage, there are many problems in the cost and production control of printed matters, and in addition to the difficulty of computerized printing factory management, friction between each printing process occurs. there was.

Accordingly, the present invention is to solve the problems described above, by measuring the total paper coefficient, the poor paper coefficient, the genuine paper coefficient of the printed matter without error, the respective counting data of the measured data, statistics, reports, etc. In addition to providing to the producers or managers, it is possible to implement the automation and computerization of production management, and to improve the production efficiency by enabling the real-time check of the use of ink per unit of work.

The object of the present invention is to provide a paper counter comprising a sample balance indicator, a main scale indicator, a paper count sensor, and a total count of counting count sensor, a web press including a rotary down circuit and an ink flow meter; A control system unit including a control card, a control unit, a monitor and an output device; It is achieved by a print counting method and an ink usage measuring method of the offset web printing machine consisting of another rotary press and a head office program for transmitting and receiving data from the control unit and a production management system using the same.

And another rotational and head office program for transmitting and receiving data from the network switch connected to the control unit.

Hereinafter, a counting method of a genuine printed matter according to the present invention will be described with reference to the following examples.

(Example 1)

In order to measure the weight of one printed matter, put up to 5, 10, 20, 30, 40 sheets of ground water on the sample balance, measure the weight, and operate the sample 1 key on the control unit to ground. The weight of water is divided by the number of copies of the print to calculate the average weight of one print.

(Example 2)

In order to calculate the coefficient value for a bundle of grounded materials, the weight of one printed matter calculated by the method of Example 1 is generally composed of 250 sheets or 500 sheets, and PP (polypropylene: polypropylene) Put the bundle of grounded materials bounded by the band on the sample balance or the main scale and measure the weight, and then operate the 'Sample 2' key on the control unit to divide the weight of the grounded material by the weight of one printed sheet to calculate the coefficient of printed matter. Way. At this time, the control unit is set to ignore the weight of the PP band.

(Example 3)

In order to calculate the coefficient value for a large amount of ground material loaded on the pallet, put the pallet loaded with the ground material on the main scale, measure the weight, and operate the 'sample 3' key on the controller to load the ground material. It is a method of calculating the count value of a printed matter by dividing the weight of the pallet by the number of bundles of ground materials calculated in Example 2. At this time, the control unit is set to ignore the weight of the PP band binding the weight of the pallet and the ground.

(Example 4)

In order to measure the number of prints using the sensor, as shown in Figure 2, by installing a paper count sensor on the upper surface of the conveyor belt for transporting the prints in the folding machine to calculate the total number of the transported prints, as shown in Figure 3 As described above, the total number of operating counting sensors is installed on one side of the printing cylinder or the grounding bin of the grounding machine to detect the rotational speed of the machine.

On the other hand, the control unit calculates the number of handwriting by subtracting the count value of the genuine printed product calculated as described above from the total number of sheets.

When one pallet is completed, the operator operates the 'Pallet Complete' key of the control unit to print out the transfer slip from the printer and notify the production management department of the result automatically.

Next, an ink usage measuring method according to the present invention will be described.

A plurality of ink supply valves connected to the printing unit of the web press are provided with an ink flow meter and a level sensor, and an indicator for displaying data provided therefrom is further provided.

The ink flow meter and the level sensor are connected to the control unit through a control card, and configured to transmit data to the control unit.

The control unit corrects the volume of the ink using the volume change coefficient according to the temperature change of the flow rate data of the ink transmitted from the ink flowmeter, and multiplies by the specific gravity of the ink to obtain the weight of the used ink.

By such a configuration, the controller can display the ink usage amount per work unit to the driver in real time, so that the driver can take appropriate measures accordingly, and the ink consumption can be checked at a glance.

The controller processes and reports the data result according to the operation of the web press as follows.

1) Print register: The number of genuine copies produced by each printer and the number of papers produced by each type of paper, the number of sheets of paper, the time required, and the total number of revolutions of the machine rotated for genuine production and the working efficiency of each group.
