Description

Head cleaning device for a label printer

The present invention relates to a head cleaning apparatus for a label printer, and more particularly, to a head cleaning apparatus for a label printer which can clean a plurality of heads mounted on a printer while a label printing paper is mounted.

With the development of printers or printers, it is possible to output not only paper or thin plastic paper, which is a conventional general output medium, but also various output media such as wooden boards, glass plates, and slabs.

Such technological advances have been made by using UV ink in printers or printers. UV ink does not cover the target output medium because it is fixed on the output medium and irradiated with ultraviolet light.

In particular, the UV inkjet technology is an eco-friendly technology that does not emit VOC (Volatile Organic Compounds), and it is already replacing the existing solvent printing market in developed countries such as Europe and the United States, and its demand is rapidly increasing.

In addition, recently, a UV label printer for printing a desired image on a label using a UV printer has been developed and in use. UV label printers are emerging as an alternative to the label printing method using the offset method as well as environmentally friendly advantages. The advantages are various data changes and a small amount of high quality output.

In the case of such label printers, only a few colors, such as yellow and red, tend to be mainly used to attract attention. Therefore, a color head which is not frequently used among the heads of the printer often causes the nozzles to be clogged or the amount of ink ejected by the ink residue on the nozzle wall is less than the standard value. At this time, if all the nozzles of the printer head are cleaned, the discharged by forced suction of ink must be discharged even for the head that is not clogged, and thus there is a problem that ink is wasted.

In addition, in the case of a label printer, the label printing paper is provided in a roll type, and the image is output by the print head while the label printing paper is continuously transferred by the rotation of the supply roll mounted on the input side and the recovery roll mounted on the output side. do. Therefore, when the head is closed when the label printing paper is already loaded, the print head is not easy to clean due to the label printing paper, so the head is cleaned after removing the label printing paper from the printer, and the label again. Printing paper is connected to the supply roll and the recovery roll is inconvenient to start the output operation. In particular, in the case of a label printer, since the position is fixed so that the print head is output at a predetermined position with respect to the label printing paper, the head cleaning through the transfer of the print head is also difficult.

An object of the present invention devised to solve the above problems is to provide a head cleaning apparatus for a label printer which can clean a plurality of heads mounted on a printer while a label printing paper is mounted.

The present invention for achieving the above object, the housing having a space therein; A negative pressure device connected to the housing to provide a negative pressure; A plurality of actuators installed inside the housing; An actuation rod that is forward and backward by the actuator and protrudes from the housing and communicates with the housing inner space; And a suction finger installed at an end of the operating rod of the actuator outside the housing, wherein the suction finger has an upper tip formed to be inserted into a space between the label printing paper and the head, and an upper portion of the upper tip. It is a head cleaning device for a label printer formed in and having a suction groove in communication with the operation rod.

The lower tip is formed integrally with the lower tip formed in the bottom of the upper tip to avoid the printing label paper can be avoided.

In addition, the operating rod is characterized in that the through-hole is formed only in the inner space of the housing.

According to the present invention, when a part of the plurality of heads of the label printer is occluded, only the heads are cleaned, and thus waste of ink can be prevented. In addition, since the cleaning can be performed while the label printing paper is mounted, the cleaning time can be reduced and the inconvenience caused by the reinstallation of the label printing paper can be eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In adding reference numerals to components of the following drawings, it is determined that the same components have the same reference numerals as much as possible even if displayed on different drawings, and it is determined that they may unnecessarily obscure the subject matter of the present invention. Detailed descriptions of well-known functions and configurations will be omitted.

Reference numeral 100 shown in FIG. 1 indicates a head cleaning apparatus 100 for a label printer according to an exemplary embodiment of the present invention.

The label printer head cleaning apparatus 100 includes a plurality of heads 12 formed below the head assembly 10 without disturbing the label printing paper 20 under the fixed head assembly 10. It is configured to allow individual cleaning. The cleaning method of the head printer 100 for label printers is performed by forcible ink suction from the head 12 by underpressure.

The label printer head cleaning apparatus 100 includes a housing 120 having a space therein, a negative pressure device 110 connected to the housing 120 to provide a negative pressure, and inside the housing 120. A plurality of actuators 130 to be installed, an actuating rod 132 which is moved forward and backward by the actuator 130, protrudes from the housing, and communicates with an inner space of the housing 120, and the housing 120 of the actuator 120. It includes a suction finger 140 is installed on the end of the operating rod 132 of the actuator 130 from the outside.

The housing 120 has a working hole through which the operating rod 132 penetrates in a front surface thereof, and the other end of the negative pressure supply pipe 112 having one end connected to the negative pressure device 110 is connected thereto. The operation hole formed in the operation rod 132 and the housing 120 should be sealed to prevent air from mixing. In addition, a drain pipe 122 is formed in the housing 120 to discharge the ink collected in the housing 120 to the outside. The drain pipe 122 may be provided with a separate drain valve (not shown) for discharging. In addition, when the ink is discharged from the housing 120, the negative pressure device 110 is turned off to prevent negative pressure from being applied.

Since the negative pressure device 110 may use a known device, detailed description thereof will be omitted here.

The actuator 130 may use a cylinder or a linear motor operated by pneumatic or hydraulic pressure. The number of excavator actuators 130 matches the number of heads 12. The output tube of the actuator 130 is integral with the operation rod 132.

The actuating rod 132 is connected to the actuator 130 and the actuating rod stays only inside the housing 120 during the movement of the actuating rod 132 in order to transmit a negative pressure inside the housing 120. One or more through-holes 134 are formed on the outer circumferential surface of a portion of 132 as shown in FIG. 1. Therefore, the negative pressure of the negative pressure device 110 is transmitted through the through hole 134, and it is possible to recover the ink sucked from the head 12 into the housing 120.

The suction finger 140 has a shape that can be inserted into the space between the label printing paper 20 and the head 12, in the embodiment of the present invention is formed in a thin plate shape. The suction finger 140 has an upper tip 146 formed to be inserted into the space between the label printing paper 20 and the head 12, and formed on the upper tip 146 and the operation rod ( And a suction groove 142 in communication with 132.

The upper tip 146 penetrates into the space between the label printing paper 20 and the head 12, and the edge is sharp to push down the label printing paper 20 and becomes thicker toward the rear side. Is thickened. Since the label printing paper 20 has a considerable length and elasticity of the material itself, deformation caused when the upper tip 146 is pushed down by the insertion of the upper tip 146 is caused by the evaporation of the upper tip 146. Can be restored.

An upper side of the upper tip 146 is formed with a suction groove 142 having a cross-sectional area equal to or greater than the shape and cross-sectional area of the head 12. The suction groove 142 is formed to deepen the ink toward the back side, that is, toward the operation rod 132 so that the ink flows according to the suction, the negative pressure is not disturbed by the sucked ink.

The lower tip 148 may be integrally formed at the lower portion of the upper tip 146 to form the avoidance groove 150 through which the label printing paper 20 may be avoided. Therefore, it is possible to prevent the label printing paper 20 from being damaged by the head printer 100 for label printers.

As shown in FIG. 3, the evacuation groove 150 is opened on only one side to prevent the label printing paper 20 from being separated, and the label printing paper 20 rather than the label printing paper 20. By allowing a margin in the width direction of the label, the contact with the edges of the label printing paper 20 can be reduced to minimize damage caused by the folding of the label printing paper 20.

Label printer head cleaning device 100 according to an embodiment of the present invention is basically formed as described above. Hereinafter, the operation of the head printer 100 for label printers will be described.

When the head 12 is closed and the output image is not clear or the required color is lacking, the cleaning operation by the head printer 100 for label printer is started.

First, the transfer of the label printing paper 20 supplied to the printer is stopped, and the operation of the head assembly 10 is also stopped. Then, the negative pressure device 110 is turned on to form an inside of the housing 120 as a negative pressure atmosphere. In this state, the finger 140 corresponding to the occluded head 12 is transferred below the head 12. The movement of the pinker 140 is driven by the corresponding actuator 130.

Accordingly, the label printing paper 20 is inserted into the evacuation groove 150 by the upper tip 146 and the lower tip 148 of the pinker 140, and the upper tip 146 of the finger 140. Negative pressure is applied to the head 12 by the suction groove 142 formed in the) to forcibly suck the ink.

The sucked ink drops into the suction groove 142 and passes through the working rod 132 to be collected into the inner space of the housing 120 through the through hole 134.

When the finger 140 is returned to its original position by the actuator 130, the label printing paper 20 emerges from the evacuation groove 150 of the finger 140, and the head 12 is similar to the cleaning start. Will be located underneath. At this time, not only the elasticity of the label printing paper 20 itself, but also a supply roll and a recovery roll for supplying the label printing paper 20, the label printing paper 20 is returned to the state before cleaning starts. And no deformation occurs.

When the ink collected in the housing 120 is accumulated in a predetermined amount or more, the ink is discharged to the outside through the drain pipe 122.

As described above, it has been described with reference to the preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.
