Patent number: 10991606Abstract: A purge stocker has a plurality of shelf zones each including a plurality of purge shelves each configured to purge inside of a storage container placed thereon with purge gas. The purge stocker includes: a flow-rate adjusting unit configured to adjust the flow rate of purge gas supplied to the purge shelves for each shelf zone; a conveying device configured to convey the storage container; and a control unit configured to control conveyance of the storage container by the conveying device. When the number of scattered empty shelves is equal to or larger than a predetermined shelf count that is the number of the purge shelves included in each shelf zone, the control unit performs shelf-changing control of causing the conveying device to transfer the storage container such that an empty shelf zone in which all of the purge shelves included therein are empty is newly formed.Type: GrantFiled: December 8, 2017Date of Patent: April 27, 2021Assignee: Murata Machinery, Ltd.Inventors: Yoshiaki Fujiwara, Koichi Sano, Mitsuya Tokumoto

Patent number: 10239101Abstract: A purge device includes an internal space defined by a chassis, and performs a purge process where an inside of a storage container in the internal space with an article being accommodated is purged with a purge gas. The purge device includes an air blower that is located outside the chassis, and sends air to an area where a gas including the purge gas in the internal space leaks through an opening in the chassis so as to diffuse the gas including the purge gas leaking from the opening.Type: GrantFiled: December 17, 2014Date of Patent: March 26, 2019Assignee: MURATA MACHINERY, LTD.Inventors: Masanao Murata, Mitsuya Tokumoto, Takashi Yamaji

Patent number: 9779973Abstract: The safety of a worker is ensured, and the area in which purging is halted is limited to the minimum. The inner space of a device is divided into a working area and a non-working area, and purging of articles in the working area is halted and the purging of the articles in the non-working area is continued. The oxygen concentration in the working area is measured, and if the oxygen concentration of the working area decreases to a predetermined value or less, the purging of the articles in the non-working area is halted.Type: GrantFiled: July 17, 2014Date of Patent: October 3, 2017Assignee: MURATA MACHINERY, LTD.Inventors: Masanao Murata, Mitsuya Tokumoto, Takashi Yamaji, Naruto Adachi
