Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liner material dust removing device, and more particularly to a liner material dust removing device for removing dust adhering to a liner material such as a disk cartridge which is not sensitive to dust and the like.

[0002]

2. Description of the Related Art Generally, for the purpose of removing dust generated from a magnetic disk and protecting the magnetic disk, a sheet-like liner is provided on the inner surfaces of the upper and lower shells constituting the cartridge body. Such a liner is generally made of a breathable non-woven fabric and cut into a predetermined shape. Also, the liner material is applied to the disc cartridge after removing dust etc. sufficiently.
Since the disk cartridge extremely dislikes dust and the like, strict conditions are imposed for removing and cleaning the dust. Conventionally, it has been considered that such a dust removal of the liner material is performed by a general dust removing device, and for example, Japanese Patent Laid-Open No. 1-28433.
As disclosed in Japanese Patent No. 78, it has been proposed to provide a suction means on a belt-shaped traveling body surface and adjust a delicate space between the suction surfaces to sufficiently remove dust.

[0003]

However, in the conventional dust removing device, it is difficult to finely adjust the suction state and the suction head of a breathable non-woven fabric, etc., and it is difficult to remove sufficient dust only by the suction means. Met. Therefore, an object of the present invention is to provide a dust removing device that can efficiently and reliably remove dust from a breathable liner material used for a disc cartridge or the like.

[0004]

SUMMARY OF THE INVENTION The present invention is a dust removing device for removing dust or the like from a breathable belt-like traveling body, and a supporting means for transferring and supporting the belt-like traveling body on a support surface having a groove. (A supporting roll), an ultrasonic wave generating head that opposes the supporting surface of the supporting means via the traveling body, and strikes the traveling body with ultrasonic waves, and the supporting surface of the supporting means via the traveling body. The above object is achieved by providing a dust removing device having a suction head that faces each other and that sucks dust generated by the ultrasonic hitting. It is desirable to dispose an electrostatic eliminating device for eliminating static electricity of the traveling body in front of the both heads, and to provide a cleaning means for cleaning the inside of the groove portion of the supporting surface of the supporting means. Further, it is preferable that the belt-shaped running body is a liner material for cleaning the magnetic disk on the inner surface of the disk cartridge body.

[0005]

The ultrasonic wave generating head of the above dust removing device not only hits the facing surface of the liner material, which is a running body, but also generates ultrasonic waves from the groove formed in the support surface of the support means on the non-opposing surface of the liner material. There is an action of reflecting and hitting, and by such ultrasonic hitting, dust from the liner material can be efficiently sucked into the suction head.

The roll surface (support surface) 3A on which the
A backup roll (supporting means) 3 for transferring and supporting
An ultrasonic wave generation head 4 that opposes the roll surface 3A of the backup roll 3 with the liner material 2 interposed therebetween and hits the liner material 2 with ultrasonic waves, and the roll surface 3A of the backup roll 3.
And a suction head 5 which faces the liner material 2 and sucks dust generated by ultrasonic hitting.

The dust removing device 1 according to the present invention will be further described. The liner material 2 is not particularly limited as long as it is a breathable belt-shaped running body, but here, the magnetic disk is cleaned on the inner surface of the disk cartridge body. It is a liner material. Before the liner material 2 is cut and applied to a disk cartridge, it is wound in a sheet shape around a supply roll or the like so that it can be run or conveyed in a belt shape. The liner material 2 is generally a breathable non-woven fabric,
A woven fabric, or a film in some cases, may be used without any particular limitation, but a nonwoven fabric is preferably used. Liner material 2
The material of can be conventionally known synthetic fiber,
Examples thereof include polyester synthetic fibers, polyamide synthetic fibers, polyacrylic fibers, polypropylene fibers, cellulose and other known resin fibers, and these can be used alone or as a mixture thereof.

As shown in FIG. 1, the cleaner head 6 faces the backup roll 3 with the liner material 2 interposed therebetween, and has an ultrasonic wave generating head 4 and a suction head 5. The ultrasonic wave generation head 4 is composed of a cylindrical body 11 having a substantially C-shaped cross section with a part cut away, and an ultrasonic wave generator 12 arranged in the cylindrical body 11. Then, the ultrasonic wave generation unit 1 of the ultrasonic wave generation head 4
3 is formed in the transverse direction of transfer of the liner material 2. The suction head 5 is composed of a tubular body 14 having a substantially C-shaped cross-section with a part cut away, and a suction device (not shown) that suctions the inside of the tubular body 14, and the suction portion 15 of the suction head 5 includes a liner material. It is formed in two transfer transverse directions.

As shown in FIG. 2, groove portions 10 are formed on the roll surface 3A of the backup roll 3. In this embodiment, the groove portions 10 are liner material 2 as shown in FIG. 2 (a).
However, as shown in FIG. 2B, the groove portions 10 may be formed to cross each other.
In FIG. 2, the groove portion 10 is drawn linearly for the sake of simplicity, but actually has a constant width and depth. Further, an electrostatic eliminator 7 is arranged in front of the cleaner head 6 so as to face the liner material 2. Such an electrostatic remover 7 removes static electricity on the surface of the liner material 2 in advance so that dust can be efficiently sucked in the subsequent stage.

According to the dust removing device for liner material according to the present embodiment constructed as described above, the liner material 2 is moved to the position of the static eliminating device 7 and the static electricity is eliminated first. Next, the liner material 2 is transferred to the position of the cleaner head 6, and the ultrasonic wave generation head 4 and the suction head 5 suction and remove dust generated by hitting the surface of the liner material 2 with ultrasonic waves. In this case, the ultrasonic wave generation head 4 not only hits the facing surface of the liner material 2 which is a running body, but also reflects ultrasonic waves from the inside of the groove portion 10 formed on the roll surface 3A on the non-facing surface of the liner material 2. Dust generated from the liner material 2 is sufficiently sucked into the suction head 5 by being hit and hit.
