Description

Inkjet Marking Device {Inkjet Marking Device}

The present invention relates to an inkjet marking device, and more particularly, to improve the reliability of printing by arranging the surface of an object to be printed once again immediately before performing printing, and printing any type of fixed type or handgun type. The present invention relates to an inkjet marking apparatus capable of maximizing the reliability of printing by maintaining a constant separation distance between an object and a head portion performing printing.

In the case of food, the standards for labeling food, food additives, utensils, containers, and packaging are established in accordance with Article 10 of the Food Sanitation Act, and Article 10-2 (1) of the Act requires matters necessary for nutrition labeling for food subject to nutritional labeling. Is defined. Through this, it aims to promote hygienic handling of food, etc., provide accurate information to consumers, and establish a fair trade order.

In addition, in the case of livestock products, by stipulating the standards for labeling livestock products in accordance with Article 6 (1) of the Livestock Hygiene Management Act, it aims to promote hygienic management of livestock products, provide accurate information to consumers, and ensure fair trade.

The marking machine is an equipment for printing barcodes, manufacturing dates, logos, etc. on the surface of food packaging or livestock products according to these laws.

These inkjet markers use the principle of an inkjet printer, but inkjet printers print on paper, whereas inkjet markers print on surfaces such as vinyl, plastic, metal, and glass. In addition, inkjet printers perform printing by moving the head, but in the inkjet marking machine, the subject to be marked is moved by a conveyor belt and printing is in progress, and depending on the usage mode, the head of the inkjet marking machine is user-friendly using a handgun type. Is directly grasped and moved along the object to be printed, and printing can proceed.

In this case, the ink jetting method of the inkjet marker includes a valve type, a continuous jet, and a piezo jet.

The valve method is a method of spraying ink using the opening and closing of the valve, and it is easy to mark characters larger than 10mm. However, the valve method has the disadvantage of slow valve operation.

Circulation method is a method in which ink passes through a charge tunnel and is projected into fine droplets at regular intervals, and marks using the difference in reaction height of ink according to the intensity of the high voltage applied from the high-voltage tunnel. to be. This circulation method enables rapid marking, but there are problems such as frequent failure of the complicated ink circulation module and clogging of nozzles or ink lines, and the cost of consumables because consumables that keep the concentration of circulating ink constant are required. There is a downside to this increase. In addition, since it is composed of one or a plurality of nozzles, there is a disadvantage in that the resolution is deteriorated by composing a character or graphic in units of dots during marking.

The piezo method is a method that compresses and sorts ink from a cartridge when a current flows and the nozzle expands, minimizing the ink drop size, enabling high-quality, high-speed marking. In addition, the problem of ink clogging in nozzles and ink lines hardly occurs. Therefore, the piezo method is widely used as a jetting method of the head in the inkjet marking machine.

Since printing is performed on a printing object such as vinyl, plastic, metal, or glass using a conventional inkjet marking machine, there is a problem in that printing is not performed smoothly when there are foreign substances such as dust or stains on the surface of the printing object. In addition, even if printing is in progress, foreign substances are removed during management, and the print contents are separated together, making it difficult to check the print contents.

In addition, in the case of a handgun type that is directly grasped and used by a user, it is difficult to maintain a constant distance between the object to be printed and the inkjet marker, so that the print size is changed or printing is not performed clearly.

Do.

In addition, the inkjet marking apparatus according to the exemplary embodiment of the present specification may further include an operation control unit for controlling the operation of the space maintaining unit and the surface arranging unit during the printing operation.

The type of material of the printing object to be marked is also very diverse, and the kind of ink accordingly is also very diverse. Accordingly, fragments of ink or fragments of a printing object may be formed on the surface of the printing surface during printing. Such debris can be a factor that deteriorates printing quality due to foreign matter.

Accordingly, the operation control unit includes a detection unit that detects a foreign substance on a surface of a printing surface of an object to be printed during printing, and a transmission unit that transmits an operation signal to the gap maintaining unit and the surface arranging unit when the foreign substance exceeds a set value. .

The detection unit may detect a reference area of the surface of the printing surface of the object to be printed. The reference width may vary depending on the type and type of content to be printed. For example, it may be 2cm X 1cm in case of horizontal printing, and 1cm X 2cm in case of vertical printing. In addition, when the characters are long horizontally, the horizontal specific gravity may increase, and when the characters are long vertically, the vertical specific gravity may increase.

The detection unit may measure the amount and size of foreign substances included in the reference area. The user can set an acceptable foreign matter measurement value according to the type of printing.

When the measurement value of the foreign matter set by the user is exceeded, a signal is transmitted to the interval maintaining unit through the transmission unit. Accordingly, the spacing maintaining unit adjusts the spacing so that the surface arranging unit may organize the printing surface surface.

Thereafter, the transmitting unit transmits a signal to the surface arranging unit, and the surface arranging unit cleans the printing surface using the air injection unit 610 or the brush unit 620. After the surface arrangement is complete, the gap maintaining unit adjusts the gap to enable printing again. During printing, the process may be continuously repeated.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, the above-described embodiments are illustrative in all respects and should be understood as non-limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included in the scope of the present invention.
