Abstract

PURPOSE:To certainly clean the interior and exterior of an ink head without pushing adhered ink in the ink head, by sliding a cleaning member with the jet surface of the ink head in such a state that an air stream is injected from the air nozzle of the ink head. CONSTITUTION:An air pump 14 is operated during the movement of an ink head 1 to inject an air stream from the air nozzle 10 of the ink head 1 and, in this state, a cleaning member 31 is slid with the jet surface of the ink head 1 to perform cleaning for peeling or wiping off the ink 40 adhered to the jet surface and the ink 41 extruded from an air layer 5. Because the cleaning member 31 is slid with the jet surface while the air stream is injected, the adhered ink is prevented from being pushed in the ink head 1. The air nozzle 10 is blocked and pressure is applied to a direction allowing air to flow in an ink chamber 4 when the cleaning member 31 is slid with the ink head 1 but the inflow of air to the ink chamber 4 can be obstructed by the surface tension of the ink.

FIG. 5 shows the structure of each of the ink heads (1a) to (1d). Such a head (1) itself is well known, and its structure and operation will be briefly explained below. When the piezoelectric vibrator (2) deforms in accordance with the recording signal and pressure is applied to the pressure propagation medium in the horn chamber (3), the thin plate (
4) protrudes toward the ink chamber (5) in contact with it. The ink chamber (5) is always filled with ink via the introduction pipe (12), and therefore, due to the protrusion of the thin plate (4), the ink in front of the protrusion protrudes from the ink nozzle (7), and then A medium ink droplet (9) is ejected from an air nozzle (10) coaxially with the ink nozzle (7).Air is pumped from an air pump (not shown) through an air introduction pipe (15) and flows between the ink nozzle (7) and the air nozzle. The ink droplets (9) gather at the center in the air chamber (8) provided between the ink droplets (10) and then jet out from the air nozzle (10) to form a high-speed air flow. Therefore, the ink droplets (9) follow this flow. With this help, they have sufficient flight speed necessary for high-speed records.

By the way, in this type of inkjet printer, the ink head comes close to the recording paper (18) during the printing operation, so the ink droplets generated when the ink droplets collide with the recording paper (18) bounce back onto the ejection surface and cause the ink droplets to bounce off the ejection surface. contaminate.

The ejection surfaces of the ink heads (1a) to (1d) are contaminated by adsorption of fibers and dust from the recording paper (18). )
This is one of the causes of nozzle clogging. In particular, with on-demand ink heads that eject ink droplets by applying a weak pressure change to the ink near the ink nozzle, as mentioned above, the ink droplets are ejected due to the weak pressurizing force. Despite the fact that only a millimeter gap was formed and there was a lot of ink droplet bouncing,
Once clogging occurs, this clogging cannot be easily recovered by itself.

In the above-mentioned inkjet printer, the intrusion of air bubbles into the inside of the ink head (1) is a problem similar to clogging of the ink head. When air bubbles enter the ink head (1), not only does it cause printing deterioration, but it also sometimes makes it impossible to eject ink droplets.

Conventionally, when cleaning the ink head described above, in order to prevent air from entering the ink chamber (5), the near pump was shut off and the cleaning member ( 31), the ejection surface of the ink head (1) was brought into sliding contact for cleaning. In other words, when the nozzle is closed with air flowing out, the air pressure increases and the ink chamber (1) of the ink head (1) increases.
5) This is because it was normally thought that air bubbles would enter the inside.

(c) Problems to be solved by the invention Ink head (
The purpose of cleaning the ejection surface in step 1) is to remove ink droplets and dust that adhere during printing, and to improve printing deterioration due to interference with dot formation and misdirection of ejected ink droplets. It is done.

However, as described above, when cleaning by sliding the ejection surface of the ink head (1) and the cleaning member (31) into contact, dirt such as ink dust attached to the ejection surface is pushed into the inside of the ink head (1). Sometimes. When dust adheres to the inside of the ink head (1), ink accumulates based on the dust, reducing the diameter of the air nozzle, preventing dot formation, and causing printing defects such as unstable direction.

(d) Means for solving the problem The present invention has an ink nozzle and an air nozzle coaxially arranged with an air layer in between, and ink droplets ejected from the ink nozzle are transferred to the air layer. A head cleaning method for an inkjet printer in which the ejection surface of an ink head that is ejected from an air nozzle through an air flow supplied from an air flow source toward the air nozzle from the outer periphery is cleaned by slidingly contacting with a cleaning member. The present invention is characterized in that the cleaning member slides into contact with the ink head ejection surface while allowing air to be ejected from the air nozzle of the head.

(E) When the working air flow is ejected, the air pressure overcomes the strong pressing force of the cleaning member, and the inflow of dust into the nozzle can be reduced. Furthermore, the ink inside the ink head that is being pushed out by the airflow can be wiped off, thereby maintaining the cleanliness inside and outside the ink head.

Also, since the nozzle is blocked and closed with a cleaning member, the pressure is thought to increase momentarily, but the nozzle diameter of the ink nozzle of the normally used on-demand ink head is small at about 40 fim. The surface tension of the ink in this portion can prevent air from flowing into the ink chamber.

The present invention allows the air pump (14) to operate during such a cleaning operation, that is, while the ink head (1) is moving, and allows air to flow from the air nozzle (10) of the ink head (1).
16), the cleaning member (31) is slid into contact with the ink (40) adhering to the ejection surface and the ink (41) that has been pushed out from the air layer (5) is peeled off or wiped off. Clean.

In addition, the ink head (1) and the cleaning member (31)
When they come into sliding contact, the air nozzle (10) is in a shut off state. Therefore, the air pressure increases momentarily, and the ink chamber (
4) A difference occurs between the pressure from inside and the air pressure from the air chamber (5), and pressure is applied in the direction in which air flows into the ink chamber (4). However, since the nozzle diameter of the ink nozzle (7) of currently used ink heads is small, typically 40 μm, the surface tension of the ink at the boundary between the end face of the ink and the inner wall of the nozzle causes The inventor has confirmed that it is possible to prevent air from entering. Furthermore, the air system and ink system use the same air pump (
14), the pressure between the two sides can be balanced while the cleaning member (31) is blocking the air nozzle (10) surface.

(G) As described in detail, according to the present invention, the air flow ejected from the air nozzle prevents adhered ink, etc. from being pushed into the ink head during cleaning. Since the air flow pushes out the residual ink, etc., the residual ink, etc. can be wiped off, so that the inside and outside of the ink head can be reliably cleaned.
