Abstract
PURPOSE: To introduce and transfer a large quantity of semiconductor parts into low temperature atmosphere continuously without disturbing the atmosphere within the apparatus, by providing a means to prevent disturbance of the low temperature atmosphere due to ambient atmosphere.
CONSTITUTION: Entrance and exit gate units 2, 3 are furnished with double doors 9 to 12, which prevent the internal low temperature atmosphere from being disturbed when charging or discharging products, and the frost from depositing of the inner wall due to air flowing inside from the outside. When a product approaches the unit 2, the door 9 is opened. When the product is placed completely inside the unit 2, the door 9 is closed, and the inside of the unit 2 is decompressed to a negative pressure by a duct 13 and the door 10 is opened to permit the product to enter a low temperature unit 1. Thus, the atmosphere in the unit 1 is maintained. When a product leaves the unit 1, the doors 11, 12 of the unit 3 are opened and closed similarly, so that the atmosphere in the unit 1 may be also maintained. Consisting of separated low temperature, gate conveyors 6, 7, 8, this system permit continuous introduction and conveyance into low temperature atmosphere.
