Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compact cleaning device for cleaning the corotron wire and corotron shield of a corona discharger.

Conventional cleaning methods for corona discharge devices can be broadly classified into two types.

The first method is to first clean the corotron shield and wire with a brush or the like, and in the second cleaning, wipe with alcohol or wipe with cloth or paper.

The second method is to place the cleaning member inside the corotron shield, and when cleaning, pull or push the cleaning knob 7 shown in Figure 1 to connect the corotron wire 2 and corotron shield 1 to the cleaning pad. Cleaning was done by sliding 5.

'6 3fl Corotron block, 4 Corotron block
The cleaner 6 is a connecting member.

Furthermore, in the past, as shown in FIG. 2, a cleaning pad 5 was provided on a support member 8 to clean the corotron shield 1 and the corotron wire 2.

Although the first method has good cleaning performance, it takes time to clean and has the disadvantage that the corotron wire 2 is cut during operation.

In addition, there were many cleaning tools, which made storage difficult.

Further, although the second method has the advantage of good operability, it has disadvantages in that it leaves residue on the corners of the corotron shield 1 and that the device itself is large and expensive.

The application example shown in FIG. 2 has the advantage of being compact and inexpensive, but when this cleaning device is attached to and detached from the corona discharger, the corotron wire 2 is attached to the cleaning pad 5.
There was a risk that the corotron wire 2 would be cut due to being pressed in between. Also, similar to the one in Figure 2, there is also the problem that there is some residue left on the corner of the corotron shield, that is, point B and %β'7? -0 Also, there was a drawback that the means for fixing the cleaning pad 5 at point A was difficult and the number of assembly steps increased.

In order to improve these 71 drawbacks, the present applicant has previously proposed a cleaning device shown in FIG.

That is, cleaning pads 5 are attached to both ends of the support member 9, and this cleaning device cleans the corotron.
When cleaning the wire 2, remove the support member 9, Ii
The cleaning pad 5 had to be slid in the longitudinal direction of the corona discharger while being pressed in the i direction.

The present invention was made in view of the above circumstances, and its purpose is to press the cleaning elastic member, which is a cleaning pad, against the corotron wire by simply pressing the cleaning elastic member against the corotron shield. To provide a cleaning device for a corona discharger that can wipe the device evenly, reduce cleaning time without cutting the corotron wire during attachment and detachment, is inexpensive, has good storage properties, and can be cleaned even by an amateur. be.

An introduction member 10 is formed on the outer side of both pieces 9a+9b of the support plate 90 serving as the support member F, and a slope 13 is formed on the introduction member 10.

Cleaning pads 5 as cleaning elastic members G are attached to the ends of both members 9a19b of the support plate 9, respectively.

Thus, if the corotron shield 1 or the corotron wire 2 of the corona discharger becomes contaminated with toner or the like, a cleaning pad 5 is inserted into the corotron shield 1.

Since the cleaning pad 5 is larger than the width of the corotron shield 1 before being inserted, it will press against the corotron shield 1 when it is inserted. However, during insertion, the cleaning pad 5 is designed so that it does not touch or only lightly contacts the corotron wire 2, so the corotron wire 2 is not cut by pushing it.

Sei NI is basically divided into two parts.

First, when cleaning, use the cleaning pad 5 as Corotron Shield 1.
The cleaning pad 5 is inserted into the interior of the corotron shield 1 as shown in FIG. 4, and the pressing contact surface between the cleaning pad 5 and the corotron shield 1 is cleaned by moving it along the longitudinal direction in this state. It is suitable for the cleaning pad 51 to be made of wool-based felt or urethane foam.

Next, by applying a force to the support plate 9 from above as shown by the arrow in FIG. Cleaning of the central portion of the corotron wire 2 and corotron shield 1, that is, the zero point, is completed by sandwiching the corotron wire 2 with both cleaning pads 5 and moving it along the longitudinal direction in this state.

After cleaning, the cleaning pad 5 is pulled out from the corotron shield 1.

What is shown in FIG. 6 is another embodiment of the present invention, in which a tooth-shaped pressing force setting guide member 11 is provided on the slope 13 of the leading member 10, and one part 9a of the support plate 9 is provided with a tooth-shaped pressing force setting guide member 11. It differs from the above embodiment in that a protruding pressing force regulating member 12 is provided on the other piece 9b1111, and when a force is applied to the support plate 9 in the direction of the arrow, the pressing force setting guide member 11 closes to the corotron shield. The corotron wire 2 can be cleaned along the corotron shield 1 with a constant pressure applied by the cleaning pad 5 to the corotron wire 2 by engaging with the upper side wall of the cleaning pad 5. When the pressure is large, the pressing force regulating member 12 comes into contact with the other part 9b of the support plate 9 to regulate this pressing force, thereby preventing the corotron wire from breaking.

Since the present invention has been described in detail above, the cleaning elastic member G'lz can be pressed against the corotron wire 2 by simply pressing it against the cleaning elastic member Gi corotron shield 1, and this corotron wire 2 can be cut. The elastic member for cleaning can be attached to and detached from the Gi corotron shield 1 without any trouble. In addition, there is no uneven wiping (unwiped residue), and the cleaning time can be shortened, and the cost is low.Not only is it easy to store, but even an amateur can clean the corona discharger.
