Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass plate cleaning apparatus, and more particularly to a cleaning apparatus for physically cleaning a thin glass plate used for a liquid crystal display panel or the like after processing it into a predetermined shape.

[0002]

2. Description of the Related Art For example, as a glass plate used for a liquid crystal display panel or the like, a thin glass plate having a thickness of about 1 mm is used. This type of glass plate is required to be in a clean state in which no foreign matter such as dust is attached, because a fine thin film electric circuit pattern is formed on the surface thereof.

When dirt such as cutting chips adheres strongly to the surface of the glass plate during processing of the glass plate, brush cleaning has been conventionally used as cleaning of the glass plate, which is performed as follows. Was there.

First, as shown in FIG. 6, a rotatable cleaning brush 3 provided with a large number of brush bristles 1 on a base 2 is arranged to face each other vertically, and the brush of the cleaning brush 3 located above is arranged. The glass plate 4 is horizontally transferred between the bristles 1 and the brush bristles 1 of the cleaning brush 3 located below.

Another cleaning device is shown in FIG. Also in this cleaning device, a rotatable cleaning brush 3 having a large number of brush bristles 1 provided in a dense state on a base 2 is used as in the cleaning device. In this cleaning device, as shown in FIG. Are arranged in a zigzag pattern at the top and bottom, and the glass plate 4 is transferred horizontally between the brush bristles 1 of the cleaning brush 3 located above and the brush bristles 1 of the cleaning brush 3 located below.

In the cleaning device shown in FIGS. 6 and 7, a plurality of cleaning brushes 3 located above and below the glass plate 4 are used.
Although not shown, they are arranged in a plane in the front-rear direction and the left-right direction with respect to the feeding direction of the glass plate 4 at predetermined intervals. Although not shown, the glass plate 4 is horizontally transferred between the cleaning brushes 3 by a feed roller rotatably arranged above and below the glass plate 4.

[0007]

By the way, the glass plate 4
If dirt or the like is strongly attached to the surface of the cleaning brush, or if the cleaning effect is to be improved, it is necessary to strongly press the bristles of the cleaning brush against the glass plate.

In such a case, in the cleaning device shown in FIG. 6, even if the brush bristles 1 of the cleaning brushes 3 positioned above and below are strongly pressed against the surface of the glass plate 4, the cleaning brush 3
Since the brush bristles 1 of the above are in a dense state, it is difficult to form the overlapped state by making the brush bristles 1 of the upper and lower cleaning brushes 3 bite into each other. As a result, as shown in FIG. 8, there is almost no overlap between the brush bristles 1 of the upper and lower cleaning brushes 3, and it is difficult to press the brush bristles 1 strongly against the glass plate 4, which improves the cleaning effect. difficult.

Even if the brush bristles 1 of the upper and lower cleaning brushes 3 are forced to bite into each other to form an overlapping state, the glass plate 4 is attempted to be inserted horizontally between the upper and lower cleaning brushes 3. In that case, the insertion resistance is large when the brush bristles 1 bite into each other,
It becomes difficult to insert the glass plate 4 between the cleaning brushes 3.

In the latter cleaning device shown in FIG. 7, since the cleaning brushes 3 are arranged in a zigzag pattern at the top and bottom, the brush bristles 1 of the cleaning brushes 3 at the top and bottom can be strongly pressed against the glass plate 4. is there. Further, since the bristles 1 of the upper and lower cleaning brushes 3 do not bite into each other, it is possible to insert the glass plate 4 between the upper and lower cleaning brushes 3.

However, when the brush bristles 1 of the upper and lower cleaning brushes 3 are strongly pressed against the glass plate 4, the glass plate 4 is transferred in a wavy curve as shown in FIG. Bending stress is applied to the thin glass plate 4, and in particular, in the case of the thin glass plate 4, the bending becomes remarkable and the damage may occur. When compared with the former cleaning device shown in FIG. 6, when the same number of cleaning brushes 3 located above and the cleaning brushes 3 located below are arranged to obtain the same cleaning effect, the latter shown in FIG. In the above cleaning device, the length of the glass plate 4 along the transfer direction needs to be doubled, which makes it difficult to effectively use the installation space.

Therefore, the present invention has been proposed in view of the above problems, and an object thereof is to achieve a good cleaning effect and to easily insert a glass plate between cleaning brushes. An object of the present invention is to provide a glass plate cleaning device capable of smoothly transferring a glass plate between cleaning brushes.

[0013]

As a technical means for achieving the above object, the present invention arranges rotatable cleaning brushes having a flocked portion composed of a large number of brush bristles vertically and positions them vertically. In a cleaning device for cleaning both front and back surfaces of a glass plate that is horizontally transferred between bristling parts of a cleaning brush while scraping the bristling part by rotation of the cleaning brush, annular flocking parts are concentrically formed at predetermined intervals. One cleaning brush arranged in a pair, and the other cleaning brush paired with the one cleaning brush, and the other cleaning brush concentrically arranging the annular bristling part so as to be located between the annular bristling parts of the one cleaning brush. And the annular bristles of one of the cleaning brushes are arranged so as to face each other in an overlapped state in which the annular bristles of the other cleaning brush enter each other between the annular bristles of the other cleaning brush.

Further, in the present invention, a large number of one cleaning brush and the other cleaning brush, which are arranged above and below the glass plate and make a pair, are arranged at predetermined intervals in the width direction and the transfer direction of the glass plate, In addition, it is desirable that the positional relationship between one cleaning brush and the other cleaning brush of the cleaning brush pair that are adjacent to each other in the width direction is vertically inverted.

[0015]

According to the present invention, one cleaning brush in which annular bristle-implanted portions are concentrically arranged at a predetermined interval and a pair of the cleaning brushes are paired with each other and are positioned between the annular bristle-implanted portions of the one cleaning brush. Since it is composed of the other cleaning brush in which the ring-shaped bristles are arranged concentrically, when both cleaning brushes are arranged facing each other, the ring-shaped bristled part of one cleaning brush is the ring-shaped bristled part of the other cleaning brush. It is possible to easily form an overlapped state by interposing each other. This makes it possible to strongly press the brush bristles of the cleaning brush against the glass plate that is horizontally transferred between both cleaning brushes.

Further, since the cleaning brushes are arranged so as to face each other in a state where the bristle-implanted portions are overlapped with each other, and the ring-shaped bristle-implanted portions are inserted, the resistance when inserting the glass plate between the bristle-implanted portions of the cleaning brush is small, Since the glass plate can be easily inserted and no bending stress is applied to the glass plate, there is no risk of breaking the glass plate.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The same parts as those in FIGS. 6 to 9 are designated by the same reference numerals, and a duplicate description will be omitted.

As shown in FIG. 1, the cleaning apparatus of the present invention has one brush brush 13a in which annular bristle portions 14a composed of a large number of brush bristles 11a are concentrically arranged on a base 12a at predetermined intervals (see FIG. 2).

The glass plate 4 horizontally transferred between the plurality of pairs of bristles 14a, 14b of b does not have a non-contact surface with the bristles 14a, 14b of the cleaning brushes 13a, 13b.

Further, it is preferable that the one cleaning brush 13a and the other cleaning brush 13b of the cleaning brush pair which are adjacent to each other in the width direction of the glass plate 4 are arranged upside down. As a result, the contact area between the flocked portions 14a, 14b of the cleaning brushes 13a, 13b and the surface of the glass plate 4 and the flocked portions 14a, 1 of the cleaning brushes 13a, 13b.
The pressure exerted by 4b on the surface of the glass plate 4 is washed so as to be even over the entire front and back surfaces of the glass plate 4.

Although the thin glass plate 4 used for a liquid crystal display panel or the like has been described in the above embodiment, the present invention is not limited to this and is applicable to other glass plate cleaning devices. Of course it is possible.

[0025]

According to the present invention, when the one cleaning brush and the other cleaning brush are vertically opposed to each other, the flocked portions mutually form an overlapped state, so that the glass plate inserted between them is disposed. The flocked portion can be strongly pressed, and a good cleaning effect can be exhibited. Further, since the resistance when inserting the glass plate between the upper and lower cleaning brushes in the overlapped flocked portion is small, the glass plate can be easily inserted. Further, since the cleaning brushes are vertically opposed to each other, bending stress is not applied to the glass plates and the glass plates are not damaged, and the glass plates can be smoothly transferred in the horizontal direction between the cleaning brushes. It is possible to provide an improved, compact and highly practical cleaning device.
