Description

Technology Field

[0001] The present invention relates to a logistics center system. More specifically, it relates to a logistics center system in which a cold storage warehouse and a cold storage warehouse are arranged on the same floor, and a conveyor belt is provided to pass between the cold storage warehouse and the cold storage warehouse. Background Technology

[0002] Generally, logistics centers handling fresh goods consist of frozen warehouses where the internal temperature is maintained below freezing and refrigerated warehouses (or ambient temperature warehouses) where the internal temperature is maintained above freezing. Nowadays, to improve logistics loading efficiency, systems are being used where frozen and refrigerated warehouses (or ambient temperature warehouses) are located within the same building.

[0003] In conventional logistics centers, a system was used in which the freezer warehouse and the cold warehouse (or ambient temperature warehouse) were configured on different floors to prevent damage to goods from freezing and to minimize heat loss occurring between the freezer warehouse and the cold warehouse (or ambient temperature warehouse). However, in the case of such a system, when moving goods between the two warehouse spaces, the movement of goods was not smooth, resulting in reduced logistics loading efficiency and increased costs.

[0004] Therefore, recently, logistics center systems in which a cold storage warehouse and a cold storage warehouse (or ambient temperature warehouse) are configured on the same floor are being introduced. In this case, in order to minimize heat loss caused by the temperature difference between the cold storage warehouse and the cold storage warehouse (or ambient temperature warehouse), it may be an important task to properly insulate the two warehouse spaces.

[0005] In the case of a logistics center where a cold storage warehouse and a cold storage warehouse (or ambient temperature warehouse) are provided adjacent to each other on the same floor, a conveyor belt is provided to cross the two warehouse spaces. Logistics can be effectively moved between the two warehouse spaces via the conveyor belt.

[0006] However, in these conventional logistics center systems, there was a problem where significant condensation occurred on the goods and the conveyor belt due to the rapid temperature change between the two warehouse spaces when goods moved between the frozen warehouse and the cold warehouse (or ambient temperature warehouse) on the conveyor belt.

[0007] In addition, there was also a problem where moisture caused by condensation penetrated the goods and conveyor belt, causing damage to the goods and conveyor belt.

[0008] In addition, there was a problem where the conveyor belt froze as it entered the cold storage with moisture accumulated on it due to condensation. The problem to be solved

[0009] The problem that this specification aims to solve is to provide a logistics center system capable of minimizing condensation on goods and conveyor belts caused by rapid temperature changes between a cold storage warehouse and a cold storage warehouse (or, an ambient temperature warehouse).

[0010] In addition, it provides a logistics center system capable of preventing the problem of damage to goods and conveyor belts caused by moisture from condensation penetrating them.

[0013] This allows for the minimization of condensation that may occur due to rapid temperature changes between the freezer warehouse and the cold storage (or ambient temperature) warehouse.

[0014] In addition, it can prevent the problem of damage to goods and conveyor belts caused by moisture penetration due to condensation.

[0018] In addition, on the transfer path of the logistics, a first buffer space formed between the first space and the control space may be included.

[0019] Additionally, the first buffer space may be formed on the control space side based on the wall partitioning the first space and the control space.

[0024] Additionally, the second buffer space may be formed on the side of the control space based on the wall partitioning the control space and the second space.

[0025] Additionally, a third through hole is formed in the wall on the control space side of the second buffer space through which logistics pass by the transfer means, and a fourth through hole is formed in the wall on the second space side of the second buffer space through which logistics pass by the transfer means, and a second air curtain unit may be included that is positioned adjacent to the third through hole to form an air curtain in the third through hole.

[0026] In addition, the second air curtain unit may be positioned on the side of the control space from the wall on the side of the control space of the second buffer space.

[0027] Additionally, it may include a third air curtain unit positioned adjacent to the fourth through hole to form an air curtain in the fourth through hole.

[0042] Embodiments of the present disclosure are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present disclosure may be embodied in various different forms and is not limited to the embodiments described herein.

[0043] Embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0044] FIGS. 1 and FIGS. 2 are plan views of a logistics center system according to one embodiment of the present specification.

[0045] FIG. 1 illustrates a configuration in which a temperature control device (130) is placed in a control space (103), and FIG. 2 illustrates a configuration in which a dehumidification device (140) is placed in a control space (103).

[0046] A logistics center system (100) according to one embodiment of the present specification may include a first space (101), a second space (102), a control space (103), and a transfer means (110), but may be implemented with some of these omitted, and additional configurations other than these are not excluded.

[0047] Referring to FIGS. 1 and 2, a logistics center system (100) may include a first space (101). The internal temperature of the first space (101) may be set to a first temperature. In a logistics center system (100) according to one embodiment of the present specification, the first temperature is below zero, and the first space (101) may be understood as a frozen storage space. For example, the first temperature may be approximately -25°C to -18°C.

[0048] A logistics center system (100) may include a second space (102). The second space (102) may be positioned adjacent to the first space (101). The internal temperature of the second space (102) may be set to a second temperature. The second temperature may be a higher temperature than the first temperature. In a logistics center system (100) according to one embodiment of the present specification, the second temperature may be understood as a zero temperature, and the second space (102) may be understood as a refrigerated storage space. For example, the second temperature may be approximately zero 10°C.

[0049] Alternatively, the internal temperature of the second space (102) may be maintained at room temperature. In this case, the second space (102) may be understood as a general storage space maintained at room temperature, and a temperature control means such as a unit cooler may not be separately provided.

[0050] Referring to FIGS. 1 and 2, a first space (101) and a second space (102) may be partitioned by a wall (W1). In FIGS. 1 and 2, with respect to the wall (W1), the first space (101) may be the left area and the second space (102) may be the right area. The wall (W1) may be provided with insulation to minimize heat loss due to the internal temperature difference between the first space (101) and the second space (102).

[0051] The logistics center system (100) may include a control space (103). The control space (103) may be formed between the first space (101) and the second space (102). The control space (103) may be placed on the path of a transport means (110) passing through the first space (101) and the second space (102).

[0052] The internal temperature of the control space (103) can be set to a third temperature. The third temperature may be a temperature between the first temperature and the second temperature. For example, if the first temperature is minus 18°C ​​and the second temperature is plus 10°C, the third temperature may be approximately plus 0°C to 5°C. However, it is not limited thereto, and the third temperature may be set to various values ​​within the range of the first temperature and the second temperature.

[0053] A logistics center system (100) may include a conveying means (110). The conveying means (110) may extend across a first space (101), a control space (103), and a second space (102). Logistics may be conveyed between the first space (101), the control space (103), and the second space (102) through the conveying means (110). For example, in a logistics center system (100) according to one embodiment of the present specification, the conveying means (110) may be a conveyor belt.

[0054] The transfer means (110) can be separated based on the fourth through hole (O4). Specifically, the fourth through hole (O4) may be equipped with a gate (not shown) for opening and closing it, and it may be preferable for the transfer means (110) to be separated based on the fourth through hole (O4) so ​​that the fourth through hole (O4) is completely closed by the gate (not shown).

[0055] The portion formed on the side of the first space (101) and / or the control space (103) relative to the fourth through hole (O4) of the conveying means (110) may be manufactured from stainless steel. For example, the conveying means (110) may be manufactured from STS304 material, which has good durability against temperature changes. Through this, even if a power outage occurs in the logistics sensor system (100) and the temperature of the first space (101) and the control space (103) rises to room temperature, failure of the conveying means (110) due to temperature changes can be prevented.

[0056] The control space (103) can serve to prevent damage to the goods and / or the transport means (110) during the process of the transport means (110) moving from the first space (101) to the second space (102). Specifically, since the temperature can be changed stepwise through the control space (103) during the process of the goods or the transport means (110) moving from the first space (101) to the second space (102), the phenomenon of condensation occurring on the goods or the transport means (110) can be reduced. In addition, as condensation decreases, moisture is reduced, thereby preventing damage to the goods and / or the transport means (110) caused by moisture penetration, and preventing the problem of the transport means (110) freezing in the first space (101) due to moisture caused by condensation.

[0057] Referring to FIG. 1, the logistics center system (100) may include a first unit cooler (121). The internal temperature of the first space (101) may be maintained by the first unit cooler (121). Depending on the size of the first space (101), the first unit cooler (121) may be provided as a single unit or as a plurality.

[0058] The logistics center system (100) may include a second unit cooler (122). The internal temperature of the second space (102) may be maintained by the second unit cooler (122). Depending on the size of the second space (102), only one second unit cooler (122) may be provided, or multiple second unit coolers may be provided.

[0059] A logistics center system (100) may include a temperature control device (130). The temperature control device (130) may be placed inside the control space (103). The temperature control device (130) may maintain the internal temperature of the control space (103) at a third temperature. Various air conditioning equipment may be used as the temperature control device (130) to maintain the indoor temperature at an appropriate temperature. For example, in a logistics center system (100) according to one embodiment of the present specification, the temperature control device (130) may be a unit cooler. Referring to FIG. 1, one temperature control device (130) may be provided in the control space (103). However, it is not limited thereto, and may be provided in multiple numbers depending on the size of the control space (103).

[0060] In contrast, the temperature control device (130) may be an air conditioning unit built-in during the design phase of the logistics center system (100). For example, the logistics sensor system (100) may have a separate air conditioning room where an air conditioner is placed, and the air in the control space (103) may flow to the air conditioner through a duct, thereby controlling the temperature of the control space (103).

[0061] Referring to FIG. 2, the logistics center system (100) may include a dehumidifying device (140). The dehumidifying device (140) may be placed inside the control space (103). The dehumidifying device (140) may be provided in a manner that is suspended from the ceiling. If the dehumidifying device (140) is provided in a manner that is suspended from the ceiling, the control space (103) can be utilized more efficiently.

[0062] Specifically, the dehumidification device (140) may include a main body (141), a duct (142), and a ventilation port (143). The main body (141), the duct (142), and the ventilation port (143) may each be installed on the ceiling. The duct (142) may be connected to the main body (141). The ventilation port (143) may be provided at the end of the duct (142).

[0063] Alternatively, the dehumidification device (140) may be provided in a stand-type configuration that is independently set up on the floor. In this case, the dehumidification device (140) can be freely positioned according to the structure of the control space (103).

[0064] The dehumidification device (140) can remove moisture from the control space (103). Specifically, when a logistics or transport means (110) moves from a first space (101), which is a frozen storage space, to a second space (102), which is a cold storage space, moisture in the air may form on its surface and cause condensation. The dehumidification device (140) can remove moisture from the control space (103), which is formed between the first space (101) and the second space (102) and through which the logistics or transport means (110) passes, thereby minimizing the occurrence of condensation on the surface of the logistics or transport means (110). Through this, it is possible to prevent moisture caused by condensation from penetrating into the logistics or transport means (110) and causing damage to them. In addition, since moisture formed on the transport means (110) can be removed through the dehumidification device (140), the problem of the transport means (110) freezing inside the first space (101) can be prevented.

[0065] Referring to FIGS. 1 and 2, the logistics center system (100) may include a first buffer space (104). The first buffer space (104) may be formed between the first space (101) and the control space (103) on the logistics transfer path. That is, logistics may pass through the first buffer space (104) during the process of moving from the first space (101) to the control space (103).

[0066] The internal temperature of the first buffer space (104) can be maintained at a temperature between the first temperature, which is the internal temperature of the first space (101), and the third temperature, which is the internal temperature of the control space (103). Unlike the first space (101) or the control space (103), where the internal temperature of the first buffer space (104) is actively controlled through the first unit cooler (121) or the temperature control device (130), the internal temperature of the first buffer space (104) can be maintained passively due to the temperature gradient between the internal temperature of the first space (101) and the internal temperature of the control space (103).

[0067] As the logistics move from the first space (101) to the control space (103) via the transport means (110), the temperature of the space can change in stages by passing through the first buffer space (104), so that condensation on the logistics or the transport means (110) can be prevented more effectively.

[0068] The first buffer space (104) can be formed on the side of the control space (103) based on the wall (W1) that separates the first space (101) and the control space (103). This improves the space utilization of the first space (101) and allows a worker to easily manage the first buffer space (104) and the first air curtain unit (151) from the control space (103).

[0069] The logistics center system (100) may include a second buffer space (105). The second buffer space (105) may be formed between the control space (103) and the second space (102) on the logistics transfer path. That is, the logistics or transfer means (110) may pass through the second buffer space (105) during the process of moving from the control space (103) to the second space (102).

[0070] The internal temperature of the second buffer space (105) can be maintained at a temperature between the third temperature, which is the internal temperature of the control space (103), and the second temperature, which is the internal temperature of the second space (102). Unlike the control space (103) or the second space (102), where the internal temperature of the second buffer space (105) is actively controlled through a temperature control device (130) or a second unit cooler (122), the internal temperature of the second buffer space (105) can be maintained passively due to a temperature gradient between the internal temperature of the control space (103) and the internal temperature of the second space (102).

[0071] As the logistics move from the control space (103) to the second space (102) via the transport means (110), the temperature of the space can change in stages by passing through the second buffer space (105), so that condensation on the logistics or the transport means (110) can be prevented more effectively.

[0072] The second buffer space (105) can be formed on the side of the control space (103) based on the wall (W4) that separates the control space (103) and the second space (102). This improves the space utilization of the second space (102) and allows a worker to easily manage the second buffer space (105) and the second air curtain unit (152) from the control space (103).

[0073] The logistics center system (100) may include a first through hole (O1). The first through hole (O1) may be formed on the side wall (W1) of the first space (101) of the first buffer space (104). Logistics may pass through the first through hole (O1) by a conveying means (110).

[0074] The logistics center system (100) may include a second through hole (O2). The second through hole (O2) may be formed on the side wall (W2) of the control space (103) of the first buffer space (104). Logistics may pass through the second through hole (O2) by a transport means (110).

[0075] The logistics center system (100) may include a third through hole (O3). The third through hole (O3) may be formed on the side wall (W3) of the control space (103) of the second buffer space (105). Logistics may pass through the third through hole by means of a transport means (110).

[0076] The logistics center system (100) may include a fourth through hole (O4). The fourth through hole (O4) may be formed on the side wall (W4) of the second space (102) of the second buffer space (105). Logistics may pass through the fourth through hole (O4) by means of a transport means (110).

[0077] The logistics center system (100) may include a first air curtain unit (151). The first air curtain unit (151) may be positioned adjacent to the second penetration (O2). The first air curtain unit (151) may form an air curtain at the second penetration (O2). By doing so, air flow between the control space (103) and the first buffer space (104) can be prevented, thereby reducing heat loss through the second penetration (O2) and effectively maintaining the temperature gradient between the first buffer space (104) and the control space (103). Additionally, during the process of a logistics or transport means (110) entering the control space (103) from the first buffer space (104), the strong wind blowing from the first air curtain unit (151) can blow away moisture formed on the surface of the logistics or transport means (110), thereby effectively reducing the occurrence of condensation.

[0078] The first air curtain unit (151) can be positioned on the side wall (W2) of the control space (103) of the first buffer space (104) to the side of the control space (103). This prevents the first air curtain unit (151) from being damaged by the cold air of the first space (101) or the first buffer space (104), and allows a worker to easily maintain the first air curtain unit (151) from the inside of the control space (103).

[0079] The logistics center system (100) may include a second air curtain unit (152). The second air curtain unit (152) may be positioned adjacent to the third penetration (O3). The second air curtain unit (152) may form an air curtain at the third penetration (O3). By doing so, air flow between the control space (103) and the second buffer space (105) can be prevented, thereby reducing heat loss through the third penetration (O3) and effectively maintaining the temperature gradient between the control space (103) and the second buffer space (105). Additionally, during the process of a logistics or transport means (110) entering the second buffer space (105) from the control space (103), the strong wind blowing from the second air curtain unit (152) can blow away moisture formed on the surface of the logistics or transport means (110), thereby effectively reducing the occurrence of condensation.

[0080] The second air curtain unit (152) can be positioned on the side wall (W3) of the control space (103) of the second buffer space (105) to the side of the control space (103). This allows the operator to easily maintain the second air curtain unit (152) from the inside of the control space (103).

[0081] Alternatively, the second air curtain unit (152) may be positioned on the side of the second buffer space (105) from the side wall (W3) of the control space (103) of the second buffer space (105). In this case, the operator can maintain the second air curtain unit (152) from the inside of the second buffer space (105).

[0082] The logistics center system (100) may include a third air curtain unit (153). The third air curtain unit (153) may be positioned adjacent to the fourth penetration (O4). The third air curtain unit (153) may form an air curtain at the fourth penetration (O4). By doing so, air flow between the second buffer space (105) and the second space (102) can be prevented, thereby reducing heat loss through the fourth penetration (O4) and effectively maintaining the temperature gradient between the second buffer space (105) and the second space (102). Additionally, during the process of a logistics or transport means (110) entering the second space (102) from the second buffer space (105), the strong wind blowing from the third air curtain unit (153) can blow away moisture formed on the surface of the logistics or transport means (110), thereby effectively reducing the occurrence of condensation.

[0083] Alternatively, the third air curtain unit (153) may not be provided in the fourth penetration hole (O4). That is, the third air curtain unit (153) performs the additional auxiliary role of the first air curtain unit (151) and the second air curtain unit (152), and may not be provided if it interferes with the operation of the gate (not shown) or the movement of logistics.

[0084] The logistics center system (100) may include a vinyl curtain (not shown). The vinyl curtain (not shown) may be formed in the first penetration (O1). The vinyl curtain (not shown) may cover the first penetration (O1). The vinyl curtain (not shown) may prevent air from flowing through the first penetration (O1) between the first space (101) and the first buffer space (104), and may help improve thermal efficiency.

[0085] Alternatively, if an air curtain unit with durability capable of operating even at a low temperature, such as the first temperature which is the internal temperature of the first space (101), is provided, this air curtain unit may be placed in the first penetration hole (O1). In this case, an air curtain is formed in the first penetration hole (O1) to more effectively block the air flow between the first space (101) and the first buffer space (104).

[0086] The logistics center system (100) may include a gate (not shown). The gate (not shown) may be positioned in a fourth through hole (O4). The gate (not shown) may open and close the fourth through hole (O4). Specifically, when the transfer means (110) is not in operation, the fourth through hole (O4) may be closed by the gate (not shown) to block air flow between the first space (101) and the second space (102). On the other hand, when logistics need to be transferred from the first space (101) to the second space (102), the gate (not shown) may be opened.

[0087] Alternatively, a gate (not shown) may be provided in a first penetration hole (O1), a second penetration hole (O2), or a third penetration hole (O3). In this case, the transfer means (110) may be separated based on the penetration hole where the gate (not shown) is placed.

[0088] Referring to the structure described above, a stepwise temperature gradient is formed between the internal temperature of the first space (101) and the internal temperature of the second space (102) through the control space (103), the first buffer space (104), and the second buffer space (105), thereby reducing heat loss due to abrupt temperature differences. Additionally, air flow between the first space (101) and the second space (102) is effectively blocked through the first air curtain unit (151), the second air curtain unit (152), the third air curtain unit (153), and a vinyl curtain (not shown), thereby reducing heat loss due to air flow.

[0089] FIG. 3 is a plan view of a logistics center system according to another embodiment of the present specification.

[0090] The detailed configuration of a logistics center system (200) according to another embodiment of the present specification that is not described below can be understood as being the same as the detailed configuration of a logistics center system (100) according to one embodiment of the present specification described in relation to FIGS. 1 and FIGS. 2.

[0091] Referring to FIG. 3, the logistics center system (200) may include a third buffer space (206). The third buffer space (206) may be formed between the second buffer space (205) and the second space (202) on the logistics transfer path. That is, logistics may pass through the third buffer space (206) during the process of moving from the second buffer space (205) to the second space (202).

[0092] The internal temperature of the third buffer space (206) can be maintained at a temperature between the internal temperature of the second buffer space (205) and the internal temperature of the second space (202). Unlike the control space (203) or the second space (202), where the internal temperature of the third buffer space (206) is actively controlled through a temperature control device (230) or a second unit cooler (222), the internal temperature of the third buffer space (206) can be maintained passively due to a temperature gradient between the internal temperature of the second buffer space (205) and the internal temperature of the second space (202).

[0093] As the logistics move from the control space (203) to the second space (202) via the transport means (210), the second buffer space (205) and the third buffer space (206) are passed sequentially, so that the temperature of the space can change in stages, thereby effectively preventing condensation from occurring on the logistics or the transport means (210).

[0094] The third buffer space (206) may be formed on the side of the second space (202) based on the wall (W4) that partitions the control space (203) and the second space (202). The third buffer space (206) may be understood as a buffer space additionally formed on the side of the second space (202) based on a gate (not shown) to more effectively prevent condensation from occurring compared to the logistics center system (100) according to one embodiment of the present specification.

[0095] The logistics center system (200) may include a fifth through hole (O5). The fifth through hole (O5) may be formed on the side wall (O5) of the second space (202) of the third buffer space (206). Logistics may pass through the fifth through hole (O5) through a transport means (210).

[0096] The logistics center system (200) may include a fourth air curtain unit (254). The fourth air curtain unit (254) may be positioned adjacent to the fifth through hole (O5). The fourth air curtain unit (254) may form an air curtain at the fifth through hole (O5). By doing so, air flow between the third buffer space (206) and the second space (202) can be prevented, thereby reducing heat loss through the fifth through hole (O5) and effectively maintaining the temperature gradient between the third buffer space (206) and the second space (202). Additionally, during the process of a logistics or transport means (210) entering the second space (202) from the third buffer space (206), the strong wind blowing from the fourth air curtain unit (254) can blow away moisture formed on the surface of the logistics or transport means (210), thereby effectively reducing the occurrence of condensation.

[0097] The fourth air curtain unit (254) may be placed on the side of the second space (202) from the side wall (W5) of the second space (202) of the third buffer space (206). A worker can easily maintain the fourth air curtain unit (254) in the wide second space (202). However, if it interferes with the logistics loading of the second space (202), the fourth air curtain unit (254) may be placed on the side of the third buffer space (206) from the side wall (W5) of the second space (202) of the third buffer space (206). In this case, a worker can maintain the fourth air curtain unit (254) in the third buffer space (206).

[0098] Some or other embodiments of this specification described above are not exclusive or distinct from one another. Some or other embodiments of this specification described above may be used in combination or combined, with their respective configurations or functions.

[0099] For example, this means that configuration A described in a specific embodiment and / or drawing and configuration B described in another embodiment and / or drawing can be combined. That is, it means that even if the combination between configurations is not directly described, combination is possible except in cases where it is described that combination is impossible.

[0100] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of this specification shall be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of this specification are included within the scope of this specification.
