Description

Logistics center system

The present invention relates to a logistics center system. More specifically, it relates to a logistics center system in which a freezer and a cold storage warehouse are arranged on the same floor and a conveyor belt runs through the freezer and the cold storage warehouse.

Usually, logistics centers that handle fresh goods have freezers with internal temperatures maintained at below zero and refrigerated warehouses (or normal temperature warehouses) with internal temperatures maintained at above zero. Nowadays, in order to improve logistics loading efficiency, a system is being used that combines freezers and refrigerated warehouses (or normal temperature warehouses) in the same building.

In order to prevent cold damage to goods and minimize heat loss between the freezer and the cold storage (or room temperature warehouse), the previous logistics center used a system with a freezer and a cold storage (or room temperature warehouse) on different floors. However, this system caused the following problems when moving logistics between the two warehouse spaces: due to the unsmooth movement of logistics, the logistics loading efficiency was reduced, resulting in increased costs.

Therefore, a logistics center system that consists of a freezer and a cold storage warehouse (or a normal temperature warehouse) on the same floor has recently been introduced. In this case, the important issue is to do a good job of heat insulation between the two warehouse spaces in order to minimize the heat loss caused by the temperature difference between the freezer and the cold storage warehouse (or a normal temperature warehouse).

When a frozen warehouse and a cold storage warehouse (or a normal temperature warehouse) are located adjacent to each other on the same floor of a logistics center, a conveyor belt is provided across the two warehouse spaces. Logistics can be effectively moved between the two warehouse spaces via the conveyor belt.

However, this previous logistics center system has the following problem: when the items move between the freezer warehouse and the refrigerated warehouse (or normal temperature warehouse) along the conveyor belt, the temperature between the two warehouse spaces changes rapidly, causing a large amount of condensation on the items and the conveyor belt.

In addition, there is also the following problem: the moisture generated by condensation penetrates into the objects and the conveyor belt, causing damage to the objects and the conveyor belt.

In addition, there is also the following problem: the conveyor belt enters the cold storage in a state where moisture is generated on the conveyor belt due to condensation, causing the conveyor belt to freeze.

The problem that this manual aims to solve is to provide a logistics center system that can minimize the phenomenon of condensation on items and conveyor belts caused by rapid temperature changes between freezer warehouses and refrigerated warehouses (or normal temperature warehouses).

In addition, a logistics center system is provided that can prevent moisture generated by condensation from penetrating into the goods and conveyor belts, thereby causing damage to the goods and conveyor belts.

In addition, a logistics center system is provided that can prevent the problem of conveyor belts freezing due to moisture generated by condensation.

In order to achieve the above-mentioned problem, the logistics center system of one aspect of the present invention may include: a first space, whose internal temperature is set to a first temperature; a second space, whose internal temperature is set to a temperature higher than the first temperature, i.e., a second temperature; a control space, which is formed between the first space and the second space; and a transfer mechanism, which transfers logistics between the first space, the control space, and the second space; the internal temperature of the control space is set to a temperature between the first temperature and the second temperature, i.e., a third temperature.

This can minimize condensation caused by rapid temperature changes between freezer warehouses and cold storage warehouses (or normal temperature warehouses).

In addition, it can prevent moisture penetration caused by condensation from causing damage to items and conveyor belts.

In addition, it can solve the problem of conveyor belt freezing caused by moisture generated by condensation.

Furthermore, it may include a temperature regulating mechanism disposed inside the above-mentioned control space, and the above-mentioned temperature regulating mechanism maintains the internal temperature of the above-mentioned control space at the above-mentioned third temperature.

Furthermore, it may include a dehumidification device, which is arranged inside the above-mentioned control space to remove moisture from the above-mentioned control space.

Furthermore, it may include a first buffer space, which is formed between the first space and the control space on the transfer path of the logistics.

Furthermore, the first buffer space can be formed on the side of the control space based on the wall that divides the first space and the control space.

Furthermore, a first through-hole for allowing logistics to pass through the above-mentioned transfer mechanism may be formed on the above-mentioned first space side wall of the above-mentioned first buffer space, and a second through-hole for allowing logistics to pass through the above-mentioned transfer mechanism may be formed on the above-mentioned control space side wall of the above-mentioned first buffer space, including a first air curtain unit arranged adjacent to the above-mentioned second through-hole to form an air curtain at the above-mentioned second through-hole.

Furthermore, the first air curtain unit can be arranged on the wall of the first buffer space on the side of the control space.

Furthermore, it may include a vinyl curtain formed at the first through opening.

Furthermore, a second buffer space may be included, and the second buffer space is formed between the control space and the second space on the transfer path of the logistics.

Furthermore, the second buffer space can be formed on the side of the control space based on the wall that divides the control space and the second space.

Furthermore, a third through-hole for allowing logistics to pass through the transfer mechanism may be formed on the side wall of the control space of the second buffer space, and a fourth through-hole for allowing logistics to pass through the transfer mechanism may be formed on the side wall of the second space of the second buffer space, including a second air curtain unit arranged adjacent to the third through-hole to form an air curtain at the third through-hole.

Furthermore, the second air curtain unit can be arranged on the wall of the second buffer space on the side of the control space.

Furthermore, it may include a third air curtain unit arranged adjacent to the fourth through-hole to form an air curtain at the fourth through-hole.

Furthermore, a third buffer space may be included, and the third buffer space is formed between the second buffer space and the second space on the transfer path of the logistics.

Furthermore, the third buffer space can be formed on the side of the second space based on the wall that divides the control space and the second space.

Furthermore, a fifth through-hole for allowing logistics to pass through the transfer mechanism may be formed on the side wall of the second space of the third buffer space, including a fourth air curtain unit arranged adjacent to the fifth through-hole to form an air curtain at the fifth through-hole.

According to this manual, the condensation caused by the rapid temperature change between the freezer and the refrigerated warehouse (or normal temperature warehouse) can be minimized.

In addition, it can prevent moisture penetration caused by condensation, which may cause damage to items and conveyor belts.

In addition, it can solve the problem of conveyor belt freezing caused by moisture generated by condensation.

Below, with reference to the accompanying drawings, the embodiments of the present invention are described in detail so that those with common sense in the technical field to which the present invention belongs can easily implement it. However, the present invention can be implemented in many different forms and is not limited to the embodiments described here.

Below, with reference to the drawings, the embodiments of the present invention are described in detail.

Figures 1 and 2 are top views of a logistics center system of one embodiment of this specification.

FIG. 1 shows a case where a temperature control device 130 is installed in the control space 103, and FIG. 2 shows a case where a dehumidification device 140 is installed in the control space 103.

The logistics center system 100 of one embodiment of this specification may include a first space 101, a second space 102, a control space 103 and a transfer mechanism 110, but some of them may be omitted for implementation, and additional structures other than these are not excluded.

Referring to FIG. 1 and FIG. 2 , the 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 the logistics center system 100 of one embodiment of the present specification, the first temperature is below zero, so the first space 101 may be understood as a refrigerated storage space. For example, the first temperature may be approximately between minus 25°C and minus 18°C.

The logistics center system 100 may include a second space 102. The second space 102 may be arranged 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 temperature higher than the first temperature. In the logistics center system 100 of one embodiment of the present specification, the second temperature is above zero, so the second space 102 may be understood as a refrigerated storage space. For example, the second temperature may be approximately 10°C above zero.

Different from this, the internal temperature of the second space 102 can also be maintained at room temperature. In this case, the second space 102 can be understood as a common storage space maintained at room temperature, and does not need to be equipped with a temperature control mechanism such as a unit cooler.

Referring to FIG. 1 and FIG. 2 , the first space 101 and the second space 102 may be divided by a wall W1. In FIG. 1 and FIG. 2 , based on 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 have a heat insulating material for minimizing heat loss caused by the internal temperature difference between the first space 101 and the second space 102.

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 arranged on a path of the transfer mechanism 110 passing through the first space 101 and the second space 102.

The internal temperature of the control space 103 can be set to the third temperature. The third temperature can be a temperature between the first temperature and the second temperature. For example, when the first temperature is -18°C and the second temperature is 10°C, the third temperature can be approximately 0°C to 5°C. However, it is not limited thereto, and the third temperature can be set in various ways within the range of the first temperature and the second temperature.

The logistics center system 100 may include a transfer mechanism 110. The transfer mechanism 110 may extend across the first space 101, the control space 103, and the second space 102. Logistics may be transferred between the first space 101, the control space 103, and the second space 102 by the transfer mechanism 110. For example, in the logistics center system 100 of one embodiment of the present specification, the transfer mechanism 110 may be a conveyor belt.

The transfer mechanism 110 can be separated based on the 4th through-port O4. Specifically, the 4th through-port O4 can be equipped with a gate (not shown) for opening and closing it. In order to completely close the 4th through-port O4 by the gate (not shown), it is preferred that the transfer mechanism 110 is separated based on the 4th through-port O4.

In the transfer mechanism 110, the portion formed on the side of the first space 101 and/or the control space 103 based on the fourth through port O4 can be made of stainless steel. For example, the transfer mechanism 110 can be made of STS304 material that has good durability against temperature changes. In this way, even if the logistics sensor system 100 has a power outage and the temperature of the first space 101 and the control space 103 rises to normal temperature, malfunctions caused by temperature changes in the transfer mechanism 110 can be prevented.

The control space 103 can play the following role: in the process of the transfer mechanism 110 moving from the first space 101 to the second space 102, it can prevent the damage of the items and/or the transfer mechanism 110. Specifically, in the process of the items or the transfer mechanism 110 moving from the first space 101 to the second space 102, the temperature can be changed in stages by the control space 103, thereby reducing the phenomenon of condensation on the items or the transfer mechanism 110. In addition, as the condensation is reduced, the humidity is reduced, thereby preventing the damage of the items and/or the transfer mechanism 110 caused by the penetration of moisture, and preventing the transfer mechanism 110 from freezing in the first space 101 due to the moisture generated by condensation.

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. One or more first unit coolers 121 may be provided according to the size of the first space 101.

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. One or more second unit coolers 122 may be provided according to the size of the second space 102.

The logistics center system 100 may include a temperature control device 130. The temperature control device 130 may be arranged inside the control space 103. The temperature control device 130 may maintain the internal temperature of the control space 103 at the third temperature. The temperature control device 130 may use various air-conditioning equipment that maintains the indoor temperature at an appropriate temperature. For example, in the logistics center system 100 of 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 a plurality of temperature control devices may be provided according to the size of the control space 103.

In contrast, the temperature control device 130 may be an air-conditioning device built-in during the design of the logistics center system 100. For example, the logistics sensor system 100 may be equipped with an air-conditioning room for the air-conditioner, and the air in the control space 103 may flow to the air-conditioner through a pipeline to adjust the temperature of the control space 103.

Referring to FIG. 2 , the logistics center system 100 may include a dehumidifier 140. The dehumidifier 140 may be disposed inside the control space 103. The dehumidifier 140 may be installed by being suspended from the ceiling. If the dehumidifier 140 is installed by being suspended from the ceiling, the control space 103 may be used more efficiently.

Specifically, the dehumidification device 140 may include a body 141, a pipe 142, and a ventilation port 143. The body 141, the pipe 142, and the ventilation port 143 may be installed on the ceiling respectively. The pipe 142 may be connected to the body 141. The ventilation port 143 may be provided at the end of the pipe 142.

Different from this, the dehumidifier 140 can also be installed in a standing manner independently standing on the floor. In this case, the dehumidifier 140 can be freely configured according to the structure of the control space 103.

The dehumidifier 140 can remove moisture from the control space 103. Specifically, when the logistics or transfer mechanism 110 moves from the first space 101, which is a refrigerated storage space, to the second space 102, which is a cold storage space, the moisture in the air will condense on its surface to produce condensation. The dehumidifier 140 is formed between the first space 101 and the second space 102 to remove moisture from the control space 103 through which the logistics and transfer mechanism 110 passes, thereby minimizing the phenomenon of condensation on the surface of the logistics or transfer mechanism 110. In this way, moisture generated by condensation can be prevented from penetrating into the logistics or transfer mechanism 110 and damaging it. Furthermore, since the moisture condensed on the transfer mechanism 110 can be removed by the dehumidification device 140, the problem of the transfer mechanism 110 freezing inside the first space 101 can be prevented.

Referring to FIG. 1 and FIG. 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 transfer path of the logistics. That is, the logistics may pass through the first buffer space 104 during the process of moving from the first space 101 to the control space 103.

The internal temperature of the first buffer space 104 can be maintained at a temperature between the internal temperature of the first space 101, i.e., the first temperature, and the internal temperature of the control space 103, i.e., the third temperature. Unlike the first space 101 or the control space 103 whose internal temperature is actively adjusted by the first unit cooler 121 or the temperature adjustment device 130, etc., the internal temperature of the first buffer space 104 can be maintained automatically due to the temperature gradient between the internal temperature of the first space 101 and the internal temperature of the control space 103.

The logistics passes through the first buffer space 104 during the process of moving from the first space 101 to the control space 103 via the transfer mechanism 110, whereby the temperature of the space can change in stages, thereby more effectively preventing condensation in the logistics or transfer mechanism 110.

The first buffer space 104 can be formed on the side of the control space 103 based on the wall W1 that divides the first space 101 and the control space 103. In this way, the space utilization rate of the first space 101 can be improved, and the operator can easily manage the first buffer space 104 and the first air curtain unit 151 in the control space 103.

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 transfer path of the logistics. That is, the logistics or transfer mechanism 110 may pass through the second buffer space 105 during the process of moving from the control space 103 to the second space 102.

The internal temperature of the second buffer space 105 can be maintained at a temperature between the internal temperature of the control space 103, i.e., the third temperature, and the internal temperature of the second space 102, i.e., the second temperature. Unlike the control space 103 or the second space 102 whose internal temperature is actively adjusted by the temperature adjustment device 130 or the second unit cooler 122, etc., the internal temperature of the second buffer space 105 can be maintained automatically due to the temperature gradient between the internal temperature of the control space 103 and the internal temperature of the second space 102.

The logistics passes through the second buffer space 105 during the process of moving from the control space 103 to the second space 102 via the transfer mechanism 110, whereby the temperature of the space can change in stages, thereby more effectively preventing condensation in the logistics or transfer mechanism 110.

The second buffer space 105 can be formed on the side of the control space 103 based on the wall W4 that divides the control space 103 and the second space 102. In this way, the space utilization rate of the second space 102 can be improved, and the operator can easily manage the second buffer space 105 and the second air curtain unit 152 in the control space 103.

The logistics center system 100 may include a first through-port O1. The first through-port O1 may be formed on a side wall W1 of the first space 101 of the first buffer space 104. Logistics may pass through the first through-port O1 via a transfer mechanism 110.

The logistics center system 100 may include a second through-port O2. The second through-port O2 may be formed on a wall W2 on the side of the control space 103 of the first buffer space 104. Logistics may pass through the second through-port O2 via the transfer mechanism 110.

The logistics center system 100 may include a third through-port O3. The third through-port O3 may be formed on a wall W3 on the side of the control space 103 of the second buffer space 105. Logistics may pass through the third through-port via the transfer mechanism 110.

The logistics center system 100 may include a fourth through-port O4. The fourth through-port O4 may be formed on a wall W4 on the side of the second space 102 of the second buffer space 105. Logistics may pass through the fourth through-port O4 via a transfer mechanism 110.

The logistics center system 100 may include a first air curtain unit 151. The first air curtain unit 151 may be disposed adjacent to the second through port O2. The first air curtain unit 151 may form an air curtain at the second through port O2. This prevents air from flowing between the control space 103 and the first buffer space 104, thereby reducing heat loss generated through the second through port O2, and effectively maintaining a temperature gradient between the first buffer space 104 and the control space 103. In addition, when the logistics or transfer mechanism 110 enters the control space 103 from the first buffer space 104, the strong wind from the first air curtain unit 151 can eliminate the moisture condensed on the surface of the logistics or transfer mechanism 110, thereby effectively reducing the generation of condensation.

The first air curtain unit 151 can be arranged on the side surface of the control space 103 on the wall W2 of the control space 103 of the first buffer space 104. In this way, the problem of the first air curtain unit 151 being damaged by the cold air of the first space 101 or the first buffer space 104 can be prevented, and the operator can easily maintain and manage the first air curtain unit 151 inside the control space 103.

The logistics center system 100 may include a second air curtain unit 152. The second air curtain unit 152 may be disposed adjacent to the third through port O3. The second air curtain unit 152 may form an air curtain at the third through port O3. Thus, air may be prevented from flowing between the control space 103 and the second buffer space 105, thereby reducing heat loss generated through the third through port O3 and effectively maintaining a temperature gradient between the control space 103 and the second buffer space 105. In addition, when the logistics or transfer mechanism 110 enters the second buffer space 105 from the control space 103, the strong wind blown out from the second air curtain unit 152 can eliminate the moisture condensed on the surface of the logistics or transfer mechanism 110, thereby effectively reducing the generation of condensation.

The second air curtain unit 152 can be arranged on the wall W3 on the side of the control space 103 of the second buffer space 105 on the side of the control space 103. In this way, the operator can easily maintain and manage the second air curtain unit 152 inside the control space 103.

Different from this, the second air curtain unit 152 can also be arranged on the side surface of the second buffer space 105 on the wall W3 on the side of the control space 103 of the second buffer space 105. In this case, the operator can maintain and manage the second air curtain unit 152 on the inner side of the second buffer space 105.

The logistics center system 100 may include a third air curtain unit 153. The third air curtain unit 153 may be disposed adjacent to the fourth through port O4. The third air curtain unit 153 may form an air curtain at the fourth through port O4. This prevents air from flowing between the second buffer space 105 and the second space 102, thereby reducing heat loss generated through the fourth through port O4, and effectively maintaining the temperature gradient between the second buffer space 105 and the second space 102. Furthermore, when the logistics or transfer mechanism 110 enters the second space 102 from the second buffer space 105, the strong wind blown out from the third air curtain unit 153 can eliminate the moisture condensed on the surface of the logistics or transfer mechanism 110, thereby effectively reducing the generation of condensation.

Different from this, the 4th through-port O4 may not be provided with the 3rd air curtain unit 153. That is, the function of the 3rd air curtain unit 153 is to further assist the functions of the 1st air curtain unit 151 and the 2nd air curtain unit 152, so it may not be provided in the case of obstructing the movement of the gate (not shown) or the movement of logistics.

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

In contrast, if a durable air curtain unit is provided that can operate even at a low temperature such as the internal temperature of the first space 101, that is, the first temperature, the air curtain unit can be disposed at the first through-port O1. In this case, an air curtain can be formed at the first through-port O1 to more effectively block the flow of air between the first space 101 and the first buffer space 104.

The logistics center system 100 may include a gate (not shown). The gate (not shown) may be disposed at the fourth through port O4. The gate (not shown) may open and close the fourth through port O4. Specifically, when the transfer mechanism 110 is not operating, the gate (not shown) may close the fourth through port O4 to block the flow of air between the first space 101 and the second space 102. On the contrary, when the logistics is transferred from the first space 101 to the second space 102, the gate (not shown) will be opened.

Different from this, the gate (not shown) can also be set at the first through-port O1, the second through-port O2 or the third through-port O3. In this case, the transfer mechanism 110 can be separated based on the through-port where the gate (not shown) is configured.

Referring to the above structure, a staged temperature gradient is formed between the internal temperature of the first space 101 and the internal temperature of the second space 102 by controlling the space 103, the first buffer space 104 and the second buffer space 105, thereby reducing the heat loss caused by the rapid temperature difference. In addition, the first curtain unit 151, the second curtain unit 152, the third curtain unit 153 and the vinyl curtain (not shown) effectively block the air flow between the first space 101 and the second space 102, thereby reducing the heat loss caused by the air flow.

Figure 3 is a top view of the logistics center system of another embodiment of this specification.

Below, the detailed structure of the logistics center system 200 of other embodiments of this specification that are not described can be understood as the same as the detailed structure of the logistics center system 100 of one embodiment of this specification described in Figures 1 and 2.

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 transfer path of the logistics. That is, the 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.

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, i.e., the second temperature. Unlike the control space 203 or the second space 202, which actively adjusts the internal temperature by the temperature adjustment device 230 or the second unit cooler 222, the internal temperature of the third buffer space 206 can be maintained automatically due to the temperature gradient between the internal temperature of the second buffer space 205 and the internal temperature of the second space 202.

When the logistics moves from the control space 203 to the second space 202 via the transfer mechanism 210, it passes through the second buffer space 205 and the third buffer space 206 in sequence, so that the temperature of the space can change in stages, thereby effectively preventing condensation from occurring in the logistics or transfer mechanism 210.

The third buffer space 206 can be formed on the side of the second space 202 based on the wall W4 that divides the control space 203 and the second space 202. The third buffer space 206 can be understood as the following buffer space: Compared with the logistics center system 100 of one embodiment of this specification, it is further formed on the side of the second space 202 based on the gate (not shown) to more effectively prevent the generation of condensation.

The logistics center system 200 may include a fifth through-port O5. The fifth through-port O5 may be formed on a side wall O5 of the second space 202 of the third buffer space 206. Logistics may pass through the fifth through-port O5 via a transfer mechanism 210.

The logistics center system 200 may include a fourth air curtain unit 254. The fourth air curtain unit 254 may be disposed adjacent to the fifth through-port O5. The fourth air curtain unit 254 may form an air curtain at the fifth through-port O5. This prevents air from flowing between the third buffer space 206 and the second space 202, thereby reducing heat loss generated through the fifth through-port O5, and effectively maintaining a temperature gradient between the third buffer space 206 and the second space 202. In addition, when the logistics or transfer mechanism 210 enters the second space 202 from the third buffer space 206, the strong wind blown out from the fourth curtain unit 254 can eliminate the moisture condensed on the surface of the logistics or transfer mechanism 210, thereby effectively reducing the generation of condensation.

The 4th air curtain unit 254 can be arranged on the side surface of the 2nd space 202 on the wall W5 on the side of the 2nd space 202 of the 3rd buffer space 206. The operator can easily maintain and manage the 4th air curtain unit 254 in the spacious 2nd space 202. However, if the logistics loading of the 2nd space 202 is obstructed, the 4th air curtain unit 254 can also be arranged on the side surface of the 3rd buffer space 206 on the wall W5 on the side of the 2nd space 202 of the 3rd buffer space 206. In this case, the operator can maintain and manage the 4th air curtain unit 254 in the 3rd buffer space 206.
