  • Publication number: 20230002115
    Abstract: The present invention aims at providing a low-temperature storage container that is highly insulated and can therefore reduce the amount of cooling medium consumption. The low-temperature storage container of the present invention includes a cylindrical container body having an opening and a storage compartment, and a plurality of holding shelves provided in the storage compartment, on which storage trays for holding storage objects are placed. The storage compartment includes a plurality of holding zones arranged in a circumferential direction of the container body, where the storage trays are held, and at least one passage zone where the storage trays pass. The holding shelves are configured as parts of a plurality of rack units that are sections arranged in a circumferential direction of the container body.

  • Publication number: 20230003754
    Abstract: To provide a simple-structured low-temperature storage system capable of carrying storage objects to a full capacity on a tray and of reliably transferring storage objects without the necessity for a camera to check the positions of a rack or storage objects. The low-temperature storage system includes a storage area inside a low-temperature storage chamber for storing storage objects, and a picking area where a positioning device is disposed to allow storage objects to be carried in and out. The positioning device includes a rack fixing unit that fixes a rack, a tray fixing unit, and a drive mechanism. The rack fixing unit includes a rack pressing member that presses the rack, and a rack motion restricting member that restricts movements of the rack. The tray fixing unit includes a tray pressing member that presses the tray, and a tray motion restricting member that restricts movements of the tray.

  • Patent number: 10661988
    Abstract: A low temperature storage system, a transport mechanism, and a low temperature storage vessel are provided, which enable downsizing and simplification of the transport mechanism, as well as stable transport of stored objects. A low temperature storage system (1) includes a low temperature storage vessel (10) and a transport mechanism (20). The transport mechanism (20) includes a reciprocating part (30) that has a holding part (35) and that is capable of reciprocating along a transfer direction, and guide unit (40). The guide unit (40) include an in-vessel guide (50) fixedly placed inside the low temperature storage vessel (10), and a telescopic guide (60) configured to be able to extend and contract along the transfer direction. The telescopic guide (60) is provided independently of the in-vessel guide (50) so as to be connectable to the in-vessel guide (50).

  • Patent number: 7378610
    Abstract: A mail sorting and distributing transfer system, which smoothly conveys mail on a mail sorting line having a compound curve whose line is not in a plane, but is three-dimensional, whereby the mail can be reliably transferred to a conveyor basket and conveying power savings are achieved. The system 100 receives mail in a transfer basket 120 hung at an outer circumferential edge of a mail sorting and distributing turn table 110 and transfers the mail through a transfer port 122 to a conveyor basket 130, which circulates on a mail sorting line O. The conveyor basket 130 includes an inner circumferential side carriage 131 and an outer circumferential side carriage 132, which respectively travel on an inner circumferential side rail 142 and an outer circumferential side rail 143 of the mail sorting line O while hanging a basket body 133 by both sides in a carried state.
