Description

Flat plate punching system for corrugated cardboard with printing means capable of digital control {thomson press system with printing device by digital control.}

The present invention relates to a flat plate punching system for a corrugated cardboard having a printing means capable of digital control, and more particularly, to corrugated cardboard supplied by forming a sheet conveying means and a printing means between an automatic paper feeding means and a pressing means. Corrugated cardboard with digital control means capable of automatically printing the printing ink to the desired position by operating the printing means at the printing position set by the printer, and automatically printing the printing ink to the desired pattern by digital control. It relates to a flat plate punching system.

The general thomson press machine (flat plate punching machine) is a device that specializes in cutting and punching corrugated cardboard and manila paper according to the development of packaging materials, and is a core device of the packaging machinery industry.

If the conventional thomson press machine does not have a printing function and wants to display information about the producers, etc. for each orderer on the wrapping paper, the packaging material is first sent to the printing machine for printing, and then the thomson press machine is punched according to the developed view.

However, even if the size and development of the cardboard box are the same, the contents of printing are different for each ordering lot, so the machine should be shut down and ready for work whenever the ordering lot is replaced.

As a result, it takes a lot of time to prepare the work, so the actual uptime of the machine is less than one third.

In other words, the printing process and the Thomson press machine are divided into two parts, which leads to an increase in labor and production logistics costs, which resulted in deterioration in profitability of packaging material producers and an increase in consumer purchase price of packaging materials.

Therefore, packaging companies producing paper processing boxes are urgently needed to develop thompson presses with printing functions in order to enhance their competitiveness.

On the other hand, the conventional printing system used in the corrugated cardboard box manufacturing industry was using a method of contacting the printed object by supplying ink to the printing plate by mounting a predetermined printing plate on the printing plate roller roller mechanically rotated.

In addition, in the manufacturing process of a general packaging box, the finished product is produced through a corrugated cardboard process, a printing process, a lamination process, a Thompson press process, a packaging process, and the like.

However, in recent years, packaging materials have also come to the age of small quantity production of various kinds of products due to shortening of product life cycle, diversification of consumer's desire, purchasing pattern, and increasing social demand for real name of producer.

As a result, whenever a small amount of production lot was replaced, regardless of the production speed, precision, or durability of the packaging material production machine, the machine had to be stopped for a day to prepare for replacement of the printing plate.

As a result, the profitability of the conventional production method is lowered, so that sustainable growth and development is difficult under the global competitive environment.

The print section is transmitted to the print control means and analyzed by the print control means so as not to deviate from the print position.

Since the configuration and operation principle of the print length analysis encoder are well known to those skilled in the art, a detailed description thereof will be omitted.

When the operator issues a job command with the keyboard, the print related program executes the job according to the command of the stored print control means.

The print length analysis encoder provides a signal to the print control means as a pulse to the print speed and print section (pattern size) in conjunction with the print means even if the speed of the press portion is variable.

The ink spray nozzle can be freely moved within the range of corrugated cardboard standard that can be produced in a direction perpendicular to the corrugated cardboard moving direction, and is used after stopping at a necessary position.

This is to cope with this when the printing position is moved in the direction perpendicular to the advancing direction.

To eliminate clogging of nozzles due to ink during printing, a highly concentrated liquid ink storage container and a solvent container for ink are separately provided for quick drying (instantaneous drying), so that ink can be ejected properly every moment when spraying ink. The ink and the material are stored separately so as to have a function of doing so.

It is equipped with a monitor which can see the printing progress data in real time, and information about the change of work order for each lot entered, lot addition, deletion, unproduced quantity, production quantity, etc. is recorded even while the machine is running.
