Abstract

PURPOSE:To shorten the time of sending ink under pressure as well as reduce the amount of unnecessary ink by a method in which the ink of an ink pipe is flowed in a dripping manner in small amounts through an outside ink chamber and an air chamber after being pressurized, and then unnecessary ink near the nozzle is discharged. CONSTITUTION:A solenoid valve 46 is closed, a solenoid valve 47 is opened, an air supply pump 45 is turned on for about 3 seconds, and a pump pressure is applied only to an ink pipe 40. Ink pushed out of the pipe 40 fills up an air chamber 41 through an outside ink chamber 39 and then begings to flow in a dripping manner only in small amounts from the nozzle 38 by pushing out nearly dried ink near the nozzle 38. Immediately thereafter, the pump 45 is turned off, the solenoid valve 46 is opened, the solenoid valve 47 is closed, the pump 45 is turned on, and unnecessary ink near the nozzle 38 is pushed out of the nozzle 38 to the outside. The ink is recovered in a discharged ink tank 43 through an ink gutter 32.

The inkjet chives F (17Y) to (17B) to which the clogging prevention method of this invention is applied will be described below. As shown in Figures 5 and 6, the Foundation increases the internal ink pressure in the inner ink chamber in response to Electrician @E3 GIC. In the inner ink layer O4, when a voltage pulse SG is applied to the piezo vibrator composed of a piezo element and a diaphragm, the vibrator contracts in the radial direction, and a bending moment is generated in the vibrations vJIfi and f361. 2. The central part of the piezo vibrator is curved into the inner ink chamber. As a result, the volume of the ink chamber c34) decreases, and the pressure of the ink liquid in the ink chamber ← increases, so that the ink acid that cannot remain in the ink mc34) is pushed out. <qn is an ink outflow passage interposed between the inner ink chamber l34) and the nozzle (to), ■ is an outer ink chamber communicating with the ink outflow passage C3D, and ink is supplied through the ink pipe (4).

In the device, inkjet heads (17Y) to (1
7B) is not used for more than one hour and there is a risk of ink clumping 9, a clogging prevention operation is performed. Specifically, when the feed operation or standby state continues for more than one hour, the clogging prevention operation is performed. When preventing clogging, the device described above uses an inkjet head (
Immediately before 17Y) to (17B) enter the idle state, the first electromagnetic pulp 616) fr: close, the second electromagnetic pulp (4 force open), and turn on the air supply pump (koma) for about 3 seconds. As shown in Figure 5, a bong pressure of about 1500 mH20 is applied only to the ink pipe (4 (1+), and the ink pipe (
The ink pushed out from 4o) is transferred to the outer ink chamber (g).
After filling the air chamber (41) to a small extent, the ink that was drying near the nozzle (to) is pushed out, and the nozzle (to) begins to flow only at sunset. Immediately after the ink begins to drip, the air supply pump is turned off, thereby minimizing unnecessary ink dripping. In this state, the ink near the nozzle C1 mark is replaced with new ink. Therefore, the nozzle (to) will not be clogged even if the printer is left for more than an hour. □ After that, when the left-to-read state is finished, the rfrI marking device will print the first print as in the normal printing state. Solenoid valve (46
1yt open, the second @magnetic pulp (4'0 is closed, and the air supply pump (451 is turned on.) Then, as shown in Figure 6, the unnecessary ink marked with nozzle C1l is pushed out from the nozzle (to). The liquid is discharged out of the bed, and then passed through the ink gutter (3 hot water) and collected in the drainage tank (43).
