Description

Decontamination apparatus and method by ink

The present invention relates to a decontamination apparatus and method by ink, and more particularly, to a decontamination apparatus and method for removing the contamination by ink using a decontamination apparatus using a solenoid.

Commonly used inkjet printers generate bubbles like soap bubbles when heat is applied to a heater of a nozzle in an ink cartridge. Ink is sprayed through the nozzle by the bubble generated in this way to form letters to be attached to the printing paper to print.

The printing method shows a font or a picture on a printing paper, and is also called a thermal inkjet method in the sense of using heat.

The number of nozzles used in such an inkjet printer is generally about 56. In addition, the font type can be downloaded by a program (Down Load), it is also possible to print a picture or a picture. The resolution of a font or a picture of such an inkjet printer is generally about 300 DPI (Dot Per Inch), and color printing is also possible depending on the type of ink cartridge to be installed.

The general structure of such a conventional inkjet printer includes a carrier supported on a main frame and moved left and right by a time belt under the guidance of a belt pulley, an ink cartridge mounted on the carrier and ejecting ink while moving together; A nozzle which is installed in the ink cartridge and ejects ink having a predetermined shape and is ejected, a plate rotatably installed on the main frame to transfer printing paper and supporting the paper during printing, and fixed to the main frame And a wiper and cap part for wiping or sealing the nozzle according to the cleaning signal at regular intervals during printing.

The ink will be removed.

When the ink is absorbed through the sponge 10b as described above, the current signal applied to the ink decontamination apparatus 10 is turned off to bring the sponge 10b into the case 10a by the restoring force of the spring 10c. Is pulled up. At this time, the sponge 10b is in close contact with the upper surface of the base frame 70 to remove the ink.

Looking at the circuit for driving such a decontamination apparatus using the accompanying drawings as follows.

As shown, from the CPU 80-1 for processing print data applied from a computer (not shown) and outputting a print control signal and an ink decontamination signal in accordance with the processed data, and from the CPU 80-1. Line feed (hereinafter abbreviated as LF) motor drive device 80-2 for receiving a print control signal outputted and outputting a control signal to supply paper, and is applied from the LF motor drive device 80-2. In response to the control signal, the LF motor 80-3 rotates to feed the paper, and the print control signal applied from the CPU 80-1 to the paper fed by the rotational force of the LF motor 80-3. The nozzle driving device 80-4 for driving the nozzle (not shown) of the ink cartridge (not shown) that ejects the ink, and the nozzle driving device 80-4 completes the printing of one line of paper. Output from the CPU 80-1 to print the next line Carriage Return (hereinafter referred to as CR) motor driving device 80-5 for outputting a control signal for moving the carrier 30 (shown in FIG. 6) according to the print control signal, and the CR motor driving. The CR motor 80-6 rotates according to the control signal output from the device 80-5 to move the carrier 30, and the current signal is received by receiving the ink decontamination signal applied from the CPU 80-1. The solenoid driving device 10-1 for outputting the current and the current signal output from the solenoid driving device 10-1 are applied to be turned on and move in accordance with the rotation of the CR motor 80-6.

Looking at the operation according to such a configuration as follows.

The print data applied from the computer is received by the CPU 80-1. The CPU 80-1 receiving the print data outputs a print control signal according to the print data, and also outputs an ink decontamination signal for ink decontamination. The print control signal output from the CPU 80-1 is applied by the LF motor drive device 80-2 to drive the LF motor 80-3 to feed the paper.

When the sheet is fed by the LF motor 80-3, the nozzle drive device 80-4 controls the nozzle to print control signals applied from the CPU 80-1 to eject ink. When the printing is completed as described above, the LF motor driving device 80-2 receives the print control signal from the CPU 80-1 and transfers a control signal for moving to the next line in order to transfer the paper to the LF motor 80-3. To be applied. The LF motor 80-3, which receives this control signal, rotates to convey the paper.

When printing on one sheet is completed through such an operation, the CPU 80-1 outputs an ink contamination removal signal. The ink decontamination signal is applied to the CR motor 80-6 and the solenoid drive device 10-1. The CR motor 80-6 receiving the ink decontamination signal rotates to move the carrier.

At this time, the solenoid drive device 10-1 applies a current signal to the ink decontamination apparatus 10 according to the applied ink decontamination signal. In the ink decontamination apparatus 10 receiving the current signal, the solenoid 10d is turned on according to the applied current signal so that the sponge 10b comes out of the case 10a and the It is attached to one side of the carrier 30 moving by rotation to absorb the ink to remove the contamination.

Such an ink decontamination method will be described with reference to the accompanying drawings.

In the idle step S10-1, it is determined through a printing determination step S10-2 whether a print command is input in a standby state for removing ink contamination.

If the print command is not inputted as a result of the determination, a return step S10-3 of returning to the printing determination step S10-2 is executed again.

In addition, when a print command is input in the printing determination step S10-2, a printing step S10-4 which executes printing is performed. In the printing step S10-4, it is determined in the printing end determination step S 10-5 whether the print job is finished. As a result of the determination, if the print job is not finished, the return step S10-6 is executed to execute the printing determination step S10-5 again.

On the contrary, when it is detected that the print job is terminated in the printing determination step S10-5, the solenoid is driven in the ink decontamination apparatus 10 (shown in FIG. 8) On step S10-7. Done. When the solenoid is driven, in the ink decontamination step S10-8, the sponge 10b protrudes out of the case 10a (shown in FIG. 4) of the ink decontamination apparatus 10, and at the same time, the CR motor 80-6; ) Is driven to cause the carrier 30 (shown in FIG. 6) to perform one reciprocating motion to remove ink contamination.

As such, when the ink contamination is removed in the ink decontamination step S10-8, the ink decontamination apparatus off step S10-9 is executed to turn off the ink decontamination apparatus 10. When the decontamination apparatus 10 is turned off, a return step S10-10 that returns to the idle step S10-1 is executed and circulated.

As described above, the ink decontamination apparatus of the present invention has the effect of easily removing the ink contamination by the ink cartridge and reducing the jam (Jam) caused by the ink decontamination apparatus to improve the reliability of the product.
