Description

  The present invention relates to a dust-free garment and a dust monitoring system.

  Conventional dust-free garments were white or light blue. This is to express a sense of cleanliness, and was not required in terms of function, particularly to improve the cleanliness.

  The conventional white or light blue dust-free garment does not show the dust attached to it, but it feels clean, but it cannot be confirmed with eyes. Therefore, they entered the clean room with dirt and brought dust into the clean room to contaminate the clean atmosphere.

  Accordingly, an object of the present invention is to provide a dust-free garment that allows easy confirmation of attached dust.

  Another object of the present invention is to provide a dust monitoring system using a dust-free garment.

  In order to achieve the above-mentioned object, the present invention is a dust-free garment characterized in that at least a part thereof is black, and the present invention also includes a cleaning room for removing dust from the dust-free garment, and dust. A dust monitoring system comprising: a dark room equipped with a light source and a camera disposed in front of a clean room in order to observe the degree of residual dust adhering to the dust-free garment after being paid.

  ADVANTAGE OF THE INVENTION According to this invention, the dustless clothing which can confirm the adhering dust easily can be obtained. In addition, a dust monitoring system using dust-free clothing can be obtained.

  The dust-free garment of the present invention is at least partially black, and the dust monitoring system of the present invention is attached to the dust-free garment after the dust is removed from the cleaning room for dust removal from the dust-free garment. It has a dark room equipped with a light source and a camera arranged in front of a clean room in order to observe the degree of residual dust.

Example 1
FIG. 1 is a front view showing the entire dust-free garment of Embodiment 1 of the present invention. In FIG. 1, the dust-free garment 10 is one in which the entire dust-free garment is colored black, and thus it can be seen that dust is clearly attached to both human eyes and machine eyes.
(Example 2)
FIG. 2 is a front view showing the entire dust-free garment of Embodiment 2 of the present invention. As shown in FIG. 2, not only the dust-free garment 10 as a whole, but also only the part where dust is likely to adhere and the part where the dust is easy to read with the human eye or camera are partially colored black. Moreover, in addition to the current dust-free garments (white, light blue), a black cloth 12 having a predetermined size can be partially attached.

  In any of the above-described embodiments, it is preferable that the surface of the black portion has less unevenness so that the dust adhering to the surface can be clearly read even on the day of the camera or on the human eye. It is preferable that rough unevenness, that is, there are few wrinkles of clothes and fine unevenness of the fiber, and the attached dust comes out on the surface without being shadowed and can be easily read.

It is preferable to reduce reflection on the surface of the black portion described above so that dust adhering to the surface can be clearly read by both human eyes and camera eyes. If the clothing fibers are glossy and reflect light, the attached dust will be difficult to read. The clothing fabric itself absorbs the light so that only the attached dust reflects and reflects the light it shines.
(Example 3)
FIG. 3 is a block diagram illustrating a dust monitoring system according to a third embodiment that uses the dust-free clothing according to the first and second embodiments. In FIG. 3, using the above-described black dust-free garment 10, before entering the clean room 18, the dust adhered in the cleaning room 14 that dusts with an air shower is removed, and then the dust-free garment 10 is still adhered or remains. In order to observe the degree of dust, a dark room 16 is provided to suppress disturbance light that interferes with observation. The dark room 16 may have a low light blocking rate and may be of a size that does not interfere with dust observation. In general, a front room for cleaning is used in front of the clean room. However, in the present invention, the function of the dark room 16 is also provided as the front room or between the front room and the clean room.

  In the dark room 16, black light is used as the light source 22 in order to make the adhering dust rise. Of course, various types of light sources are used to make any dust stand out. However, the dust of clothes that easily contains a fluorescent agent in the detergent shines very efficiently when exposed to black light, thus improving the dust detection rate.

  Use of the infrared light source 22 and the infrared camera 20 makes it easy to see dust adhering to the dust-free garment 10. The light source 22 or the camera 20 is equipped with various optical filters (not shown) that make it easy to see dust, and can cope with various dusts. By combining the light source 22 and the filter, dust that is not normally visible can be visualized, so that advanced dust monitoring is possible.

  In the present invention, the dust adhering to the black portion of the surface of the dust-free garment 10 is imaged by the camera 20, the degree of dust adhesion is displayed, and / or compared with a predetermined degree of dust adhesion. If you have a dust alarm system that will alert you.

Conventionally, since dust is only removed for a predetermined time with an air shower, the clean room 18 is often contaminated. According to the present invention, the carrying-in of human dust, which has been conventionally taken up as a problem, is reliably suppressed.
Example 4
FIG. 4 is a block diagram showing a control flow of the dust monitoring system. As shown in FIG. 4, in the dark room 16, dust attached to the dust-free garment 10 is imaged by the camera 20. Next, the imaged data is subjected to signal processing (30), and dust counting (32) is performed. Next, the number of dust adhesion tolerances (34) is compared with the dust count, and pass / fail judgment (36) is performed. The result is displayed (38), and the opening / closing of the door 28 is controlled by the door opening / closing control (40).

  As a result of the pass / fail determination, when the degree of residual dust is large, entry into the clean room 18 can be refused. Specifically, it refuses to open the door 28 and refuses to move forward. Thereby, complete dust carrying-in can be prevented and cleanliness, such as a clean room, can be maintained.

It is a front view which shows the whole dust-free garment of Example 1 of this invention. It is a front view which shows the whole dust-free garment of Example 2 of this invention. It is a block diagram which shows the dust monitoring system of Example 3 using the dust-free clothes of Examples 1 and 2. It is a block diagram which shows the flow of control of a dust monitoring system.
