Description

Item storage device and item storage method

[0001] The embodiments disclosed in this document relate to an item storage device and a method for storing an item, and more specifically, to an item storage device and a method for storing an item capable of maintaining an internal air composition.

[0002] When fresh food is stored in a standard refrigerated warehouse, oxidation can occur over time, potentially affecting the quality of the food. Conventional fresh food storage methods utilize a Controlled Atmosphere (CA) system, which prevents food oxidation by lowering the oxygen content and increasing the nitrogen and carbon dioxide content within the warehouse.

[0003] However, conventional fresh food storage methods have drawbacks, such as the need to adjust internal concentration ratios in real time, which incurs a cost burden, and the low internal oxygen density that can cause oxygen deficiency among workers during shipping and internal operations. Furthermore, the larger the warehouse, the greater the cost and time required to maintain the internal concentration. Accordingly, there is a need for a system that maintains the air composition inside the storage unit during product entry and exit, while allowing workers to frequently manage the inbound and outbound processes from the outside.

[0004] In this regard, prior art documents such as KR100359829B1 or KR100379488B1 may be referenced.

[0005] According to the method of the present disclosure, an item storage device and an item storage method capable of receiving and releasing items while maintaining the internal air composition may be provided.

[0041] FIG. 2 shows a cross-sectional view of an item storage device according to one embodiment.

[0042] Referring to FIG. 2, the item storage device (100) may include a port (210), a first chamber (220), and a second chamber (230). The item storage device (100) may include a first door (240) provided between the port (210) and the first chamber (220), and a second door (250) provided between the first chamber (220) and the second chamber (230). The item storage device (100) may include a first air moving device (260) connected between the port (210) and the first chamber (220), and a second air moving device (270) connected between the first chamber (220) and the second chamber (230). At this time, the second chamber (230) may include a first up-down line (231), at least one movable item storage line (233), and a second up-down line (235).

[0043] According to one embodiment, items being received and shipped may be placed in the port (210). The composition of the air measured in the port corresponds to the composition of the outside air, which may correspond to the composition of normal atmospheric air (about 78% nitrogen, about 21% oxygen, and 1% other (argon, carbon dioxide, neon, helium, etc.)). The first chamber (220) may be shielded from the outside of the item storage device (100) where the port (210) is located by the first door (240), and the second chamber (230) may be shielded from the first chamber (220) by the second door (250). The port (210) and the second chamber (230) may be connected with the first chamber (220) in between, but may have different atmospheric compositions by being shielded by at least one of the first door (240) and the second door (250). In one embodiment, the air composition of the second chamber (230) may have a lower oxygen specific gravity compared to the general atmospheric air composition. Items may be received from the port (210) into the second chamber (230) or released from the second chamber (230) to the port (210).

[0044] According to one embodiment, the first air transfer device (260) can move air inside the first chamber (220) to the outside of the item storage device (100) or move air outside the item storage device (100) to the inside of the first chamber (220). The first air transfer device (260) may include an air transfer device such as a pump or a valve. Additionally, although not shown in FIG. 2, the item storage device (100) may further include a first item transfer device controlled by a processor (110) that can move items from the port (210) to the first chamber (220) and from the first chamber (220) to the port (210). An incoming item may be located in the port (210). When an incoming item is detected in the port (210), the processor (110) may open the first door (240) and control the first item transfer device to move the incoming item from the port (210) to the first chamber (220). At this time, since the second door (250) is closed, the air composition inside the second chamber (230) can be maintained. When an incoming item is placed in the first chamber (220), the processor (110) can close the first door (240) and control the first air transfer device (260) to discharge the air inside the first chamber (220) to the outside of the item storage device (100). In one embodiment, the first air transfer device (260) can discharge the air inside the first chamber (220) until the inside of the first chamber (220) corresponds to a vacuum state. Afterward, when the air composition inside the first chamber (220) corresponds to a set condition, the second door (250) can be opened while the first door (240) is closed.

[0045] According to one embodiment, the second air transfer device (270) can transfer air from inside the first chamber (220) into the second chamber (230) or transfer air from inside the second chamber (230) into the first chamber (220). The second air transfer device (270) may include an air transfer device such as a pump or a valve. The processor (110) can control the second air transfer device (270) to transfer air from inside the second chamber (230) into the first chamber (220) in response to the discharge of air from inside the first chamber (220). In one embodiment, the second air transfer device (270) can transfer air after the discharge of air from inside the first chamber (220), and in another embodiment, the second air transfer device (270) can transfer air from inside the second chamber (230) into the first chamber (220) together with the discharge of air from inside the first chamber (220).

[0046] According to one embodiment, although not illustrated in FIG. 2, the item storage device (100) may further include a second item moving device controlled by a processor (110) that can move items from the first chamber (220) to the second chamber (230) and from the second chamber (230) to the first chamber (220). When a set condition is satisfied and the second door (250) is opened, the processor (110) can control the second item moving device to move incoming items from the first chamber (220) to the second chamber (230).

[0047] According to one embodiment, the second door (250) may be opened when an item is placed in the first chamber (220) and the air composition of the first chamber (220) satisfies a set condition. The set condition may be satisfied when the air composition inside the first chamber (220) corresponds to the composition of the item preservation gas. The composition of the item preservation gas may correspond to the air composition inside the second chamber (230), which may correspond to an air composition having a lower oxygen specific gravity compared to the general atmospheric air composition. For example, the composition of the item preservation gas may correspond to an air composition having a specific gravity of 97% nitrogen and 3% oxygen. At this time, since the first door (240) is closed, the air composition inside the second chamber (230) may be maintained.

[0048] According to one embodiment, although not illustrated in FIG. 2, the item storage device (100) may further include a preservation gas supply device that supplies an item preservation gas into the second chamber (230) to maintain the air composition inside the second chamber (230). The item preservation gas may include nitrogen gas. The air composition inside the second chamber (230) may correspond to an air composition of 3% oxygen and 97% nitrogen.

[0049] According to one embodiment, the second chamber (230) may include a first up-down line (231), at least one movable item storage line (233), and a second up-down line (235). Incoming items introduced from the first chamber (220) into the second chamber (230) may be located on the first up-down line (231). The first up-down line (231) may include a lift system and a ball screw and a linear shaft included in the lift system. The processor (110) may move the incoming items in an up-and-down direction through the first up-down line (231). The processor (110) may move the incoming items to at least one movable storage line (233) connected to the first up-down line (231) for loading. The processor (110) may move the incoming items in a left-and-right direction through at least one movable storage line (233).

[0050] According to one embodiment, the processor (110) can match information about an incoming item with a location on at least one movable item storage line (233) where the incoming item is placed. Based on the matching result, the processor (110) can control a first up-down line (231) and at least one movable item storage line (233) to proceed with the item incoming process. The processor (110) can further control a second up-down line (235) to proceed with the item incoming process.

[0051] According to one embodiment, the processor (110) can match information about an incoming item with a location on at least one mobile item storage line (233) where the incoming item is placed, based on a sensor. The sensor may include a camera sensor. The sensor may be included in a port (210). In one embodiment, the processor (110) can identify the location on at least one mobile item storage line (233) where the incoming item is placed through the sensor based on a barcode attached to the incoming item. Although the description in the embodiment is based on a barcode, the incoming item may be identified using a different type of tag attached to the incoming item, and the location of the corresponding item on at least one mobile item storage line (233) may be mapped to the identified item to proceed with the shipment.

[0052] According to one embodiment, each movable item storage line included in at least one movable item storage line (233) can be connected to a first up-down line (231) through one end and connected to a second up-down line (235) through the other end to be controlled.

[0053] According to one embodiment, the processor (110) can proceed with the item dispatch process based on the matching result. Based on the matching result and the dispatch item information, the processor (110) can proceed with the item dispatch process by controlling the first up-down line (231), at least one movable item storage line (233), and the second up-down line (235) according to the location of the item.

[0054] According to one embodiment, although not illustrated in FIG. 2, the item storage device (100) may further include an output interface that displays the air composition inside the first chamber (220). The processor (110) may control the first door (240) and the second door (250) to maintain the air composition inside the second chamber (230) during the item receiving and receiving process. To this end, the processor (110) may control the first door (240) and the second door (250) only when the air composition inside the first chamber (220) satisfies certain conditions. The processor (110) may display the air composition inside the first chamber (220) through the output interface for user safety or to maintain the air composition of the second chamber (230). The processor (110) may provide a warning through the output interface if the second door (250) is opened when the air composition inside the first chamber (220) does not satisfy the set conditions. The set condition can be satisfied if the air composition inside the first chamber (220) corresponds to the air composition inside the second chamber (230).

[0055] According to one embodiment, the processor (110) can proceed with the outgoing item outgoing process. The processor (110) can obtain an outgoing request including outgoing item information. Based on the outgoing request, the processor (110) can control the first air moving device (260) to discharge air inside the first chamber (220) to the outside of the item storage device (100), and control the second air moving device (270) to move air inside the second chamber (230) into the first chamber (220). After the discharge of air inside the first chamber (220), the processor (110) can move air inside the second chamber (230) into the first chamber (220). In another embodiment, the discharge of air inside the first chamber (220) and the movement of air inside the second chamber (230) into the first chamber (220) may occur simultaneously. The processor (110) can open the second door (250) when the air composition inside the first chamber (220) corresponds to a set condition. The set condition can be satisfied when the air composition of the first chamber (220) corresponds to the air composition of the second chamber (230). At this time, the first door (240) may be closed, and accordingly, the air composition inside the second chamber (230) may be maintained.

[0056] According to one embodiment, the processor (110) can control the first up-down line (231), at least one movable item storage line (233), and the second up-down line (235) based on the outgoing item information to move the outgoing item to the first up-down line (231). When the second door (250) is opened because a set condition is satisfied, the processor (110) can control the second item moving device to move the outgoing item from the second chamber (230) to the first chamber (220).

[0057] According to one embodiment, when the outgoing item is located in the first chamber (220), the processor (110) can close the second door (250) and control the second air moving device (270) to move the air inside the first chamber (220) into the second chamber (230). Afterward, the processor (110) can control the first air moving device (260) to move the air outside the item storage device (100) into the first chamber (220) and open the first door (240). At this time, the second door (250) may remain closed, and accordingly, the air composition inside the second chamber (230) may be maintained. When the first door is opened, the processor (110) can control the first item moving device to move the outgoing item from the first chamber (220) to the port (210) and close the first door (240).

[0058] FIG. 3 shows a plan view of an item storage device according to one embodiment.

[0059] Referring to FIG. 3, the processor (110) can carry out the receiving and shipping process of items based on a conveyor structure (310) included in the port (210), a conveyor structure (320) included in the first chamber (220), and a conveyor structure (330, 341, 343, 345, 347, and 350) included in the second chamber (230). The processor (110) can carry out the receiving and shipping process of items based on a tote in conjunction with the conveyor structure (310, 320, 330, 341, 343, 345, 347, and 350), although not shown in FIG. 3. A tote may refer to an open container used for storing and transporting items.

[0060] In one embodiment, the processor (110) can move items in the left-right direction through conveyor structures (310, 320, 341, 343, 345, and 347) and move items in the up-down direction through conveyor structures (330 and 350). The conveyor structures (310, 320, 330, 341, 343, 345, 347, and 350) may correspond to segmented conveyor structures. The segmented conveyor structures are controlled independently and can move items. For example, conveyor structures (343) and conveyor structures (345) may be controlled so that multiple items move in different directions at the same time.

[0061] Figure 4 shows the process of receiving an item according to one embodiment.

[0062] In step S410, the processor (110) can detect an incoming item located at the port (210).

[0063] In step S420, the processor (110) can open the first door (240) and control the first item moving device to move the incoming item from the port (210) to the first chamber (220).

[0064] In step S430, when an incoming item is located in the first chamber (220), the processor (110) can close the first door (240), control the first air moving device (260) to discharge the air inside the first chamber (220) to the outside of the item storage device (100), and control the second air moving device (270) to move the air inside the second chamber (230) into the first chamber (220).

[0065] In step S440, the processor (110) can determine whether the air composition inside the first chamber (220) satisfies a set condition. The set condition may be satisfied if the air composition inside the first chamber (220) corresponds to the air composition inside the second chamber (230).
