Abstract

PURPOSE:To permit to keep the insides of a clean air chamber and a conveying box as well as an article to be conveyed clean by a method wherein a cleaning process mechanism, replacing the inside air of connecting section between the carrying box and the clean air chamber with glean gas, is provided in the title device. CONSTITUTION:When an article 8 is transferred between a conveying box 4 and a clean air chamber 1, the conveying box 4 is carried at first under a condition that both of doors 2, 5 are being closed and the opening 6 of the carrying box 4 is connected to the opening 3 of the clean air chamber 1 through a connecting section 7. Subsequently, a cleaning process mechanism 10 is operated to discharge air in a space 9 enclosed by the doors 2, 5 and the connecting section 7 through an air discharging port 11 and clean a circumstance in the space 9. Thereafter, the doors 2, 5 are opened to transfer the article 8. According to this method, adhesion of dust to the article 8 in case of delivering it from the conveying box 4 into the clean air chamber 1 may be precluded.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for transporting articles that must be protected from dust.

[Conventional technology]

Conventionally, when transporting items that need to be transported in clean conditions, they are transported in a transport box that maintains cleanliness. The transport box is carried into a clean air chamber with the articles still in it, and after the outer surface of the transport box is cleaned, the transport box is opened and the articles are taken out. In addition, in recent years, as shown in Figure 3,
The opening 3 with the door 2 of the clean air chamber 1 and the opening 6 with the door 5 of the transport box 4 are connected by a connecting part 7, and the doors 2 and 5 are opened while being isolated from the outside space. , the article 8 is also transferred.

[Problem that the invention seeks to solve]

In the above-mentioned conventional transportation device, the clean air chamber may be contaminated by bringing the transportation box with dust on it into the clean air chamber. In addition, in the transport device shown in FIG. 3, dust in the unclean air in the closed space 9 surrounded by the doors 2, 5, and the connecting part 7 may adhere to the goods 8 and the inside of the transport box 4, and the clean air chamber It had the disadvantage of being inside 1.

The present invention solves the above-mentioned problems and provides a transport device that prevents dust from adhering to articles when they are transported from a transport chamber to a clean air chamber.

[Means for solving problems]

The present invention provides a transportation device that transports articles stored in a transportation box to a clean air chamber, communicates the transportation box and the clean air chamber through a connecting portion, and transports the articles from the transportation box into the clean air chamber. The transportation device is characterized in that it has a purification mechanism that replaces the internal air of the connecting portion with clean gas.

〔Example〕

Next, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, an opening 3 of a clean air chamber 1 is provided with a door 2, and an opening 6 of a transport box 4 is provided with a door 5. The connecting part 7 provided at the opening 3 of the clean air chamber l has a
A purification processing mechanism IO for replacing the gas with clean gas is connected, and an air outlet 11 is provided at the bottom of the connecting portion 7.

In this embodiment, when transferring the article 8 between the transport box 4 and the clean air chamber l, the transport box 4 is first transported with both doors 2 and 5 closed, and then transported by the connecting part 7. The opening 6 of the box 4 and the opening 3 of the clean air chamber 1 are connected. Next, the purification processing mechanism 10 is activated to discharge the air in the space 9 surrounded by the doors 2, 5, and the connecting portion 7 from the air outlet 11, thereby purifying the atmosphere in the space 9. After that, the door 2 and the door 5 are opened and the article 8 is transferred.

FIG. 2 is a cross-sectional view of another embodiment of the invention.

In this embodiment, the connecting portion 17 is connected to the opening 6 of the transport box 4.
It has a flexible structure.

Furthermore, the door 2 provided at the opening 3 of the clean air chamber 1 can be controlled so as to remain partially open, rather than fully opened. In this embodiment, a clean air chamber 1 is used as the purification processing mechanism 10. That is, in this embodiment, when transporting the article 8, with both doors 2 and 5 closed,
The transport box 4 is fixed in a position where both openings 3 and 6 face each other, and then the connecting part 17 is extended and connected to the opening 3, and the door 2 is partially opened to drain the air in the clean air chamber 1 into the space 9. The non-clean air in the space 9 is discharged from the outlet 11, and after the atmosphere in the space 9 has been purified, both doors 2 and 5 are opened, and the articles 8 are placed in the clean air chamber 1 and the transport box 4. Transfer between.

In the first embodiment of the present invention, the purification processing mechanism 10 may be a device that removes dust from the air and pumps the air.
Obviously, pipes supplying clean dry air or dry nitrogen are also possible. Further, in the second embodiment, the door 2 was partially opened to exhaust the air in the space 9, but a small door that can be opened and closed may be provided in a part of the door 2, or the door 2 may be A small door may be separately provided to connect the clean air chamber 1 and the space 9.

〔Effect of the invention〕

As explained above, the present invention cleans the atmosphere in the space between the clean air chamber and the transport box before transferring the goods, thereby keeping the clean air chamber, the inside of the transport box, and the goods clean. This has the effect that it can be transferred without any change.
