Description

Storage device

The present disclosure relates to a storage device.

Conventionally, storage devices are known that are installed in stores, outdoors, etc., and are used to deliver goods such as food (see Patent Document 1, for example).

The food terminal (storage device) of Patent Document 1 has two zones with different set temperatures. One zone is set at −18° C. for frozen food storage and another zone is set at +2° C. for storage of dairy products and the like. Each area has a transport box for storing frozen foods, dairy products, and the like. These zones with different set temperatures are lined up in the front-to-rear direction as seen by the delivery company (user of the grocery terminal). Of the two zones, the zone with the higher temperature setting is located closer to the inner console than the zone with the lower temperature setting. A loader for unloading a tote from each zone is located to the left of each zone as viewed from the carrier. The loader, by moving back and forth, picks up the tote box into which the carrier puts the item and moves it to the internal console. Once the carrier has loaded the items into the tote on the inner console, the loader moves the tote back to its original position by moving backwards.

Japanese Patent Application Laid-Open No. 2020-193107

In the grocery terminal of Patent Document 1, the loader is configured to horizontally reciprocate between positions facing two areas. Therefore, the loader does not have to pass in front of the area with the lower temperature setting when putting the articles into the transport box in the area with the higher temperature setting. However, when putting an article into a transport box in a zone with a low temperature setting, it is necessary to pass in front of a zone with a high temperature setting. For this reason, the length of the loader of the grocery terminal in the moving direction becomes long.

An object of the present disclosure is to solve the above problems, and to provide a storage device capable of suppressing an increase in size of the storage device.

The storage apparatus of the present disclosure partitions a housing and the interior of the housing into a first article storage space and a second article storage space, and generates an air curtain that is sucked into the first article storage space. an air curtain generating device for generating air curtains, a temperature adjusting device for adjusting the temperature of the air forming the air curtain, and a conveying device for conveying articles between the first article storage space and the second article storage space. , provided.

A second air curtain C2 is generated by the second cooling air A2 forwarded by the second fan 312 .

The air in the second air curtain C2 flows into the freezer storage 22. The air flowing into the freezer storage 22 adjusts the temperature inside the freezer storage 22 to a freezing temperature (-20° C., for example). The air that has flowed into the freezer storage 22 passes through the through portion 222A of the back plate 222 and flows into the second flow path 33, that is, the second duct D2.

When the air in the second air curtain C2 passes in front of the freezer storage 22, heat is exchanged between the air in the second air curtain C2 and the air in the first air curtain C1. This heat exchange lowers the temperature of the air in the first air curtain C1 to the refrigerating temperature. Part of the air that has passed in front of the freezer storage 22 is guided rearward by the intermediate plate member 223 and flows into the second flow path 33, that is, the second duct D2. At this time, the extending portion 223A separates the two air curtains that flow down in parallel into two again, and prevents the relatively low-temperature air on the rear side from flowing into the portion that has reached the refrigerating temperature on the front side. . The air that has flowed into the second flow path 33 is guided to the rear opening of the lower duct 311 together with the air that has passed through the through portion 222A of the back plate 222, and is again subjected to heat exchange in the second heat exchanger 417. used.

The air of the first air curtain C1 that has undergone heat exchange with the air of the second air curtain C2 flows into the cold storage 23 . The temperature inside the cold storage 23 is adjusted to the refrigerating temperature (for example, +3° C.) by the air that has flowed into the cold storage 23 . The air that has flowed into the refrigerator storage 23 passes through the through portion 232A of the back plate 232 and flows into the first flow path 34, that is, the first duct D1.

After passing in front of the refrigerator storage 23, part of the air in the first air curtain C1 is guided rearward by the lower plate member 233 and flows into the first flow path 34, that is, the first duct D1. . The air that has flowed into the first flow path 34 passes between the second flow path 33 and the rear wall portion 214 together with the air that has passed through the through portion 232A of the back plate 232, and reaches the rear side of the upper duct 321. and is reused for heat exchange in the first heat exchanger 415 .

(Incoming/outgoing operation)
Next, the operation of loading and unloading the article Z will be described. A person (for example, a store clerk, a delivery person) who stores the article Z operates the operation panel 25 when storing the article Z in the storage device 1, and the storage temperature (normal temperature, refrigeration temperature, freezing temperature) of the article Z, Enter information about the recipient of item Z; Information such as the storage temperature of the article Z may be acquired by the storage device 1 through a communication line. The information to be input when the article Z is received may be optically or electromagnetically input by a two-dimensional code or wireless tag attached to the article Z. may be optically or electromagnetically transferred to

The operation control unit determines the storage position of the item Z based on the storage temperature of the item Z input by the warehousing person. For example, when the storage temperature of the article Z is the refrigeration temperature, the operation control unit determines a position where the article Z is not stored in the refrigerator storage 23 as the storage position. The article holding section 51 conveys the storage box 20 at the storage position determined by the operation control section to the placement section 262 of the loading/unloading section 26 . When the warehousing person puts the article Z into the storage box 20 placed on the placement section 262, the article holding section 51 returns the storage box 20 placed on the placement section 262 to the original storage position. The operation control unit transmits the receiver's identification information (for example, password) to the receiver's terminal device based on the receiver's information input by the warehousing person, for example.

On the other hand, when the recipient of the article Z (for example, the purchaser of the article Z) receives the article Z from the storage device 1, he operates the operation panel 25 and inputs the identification information. The operation control unit identifies the storage position of the article Z of the recipient based on the identification information input by the recipient. The article holding unit 51 transports the storage box 20 at the storage position specified by the operation control unit to the placing unit 262 of the loading/unloading unit 26 . The recipient takes out the article Z from the storage box 20 transported to the loading/unloading section 26 . When the warehousing person takes out the article Z from the storage box 20, the article holding section 51 returns the storage box 20 placed on the placement section 262 to the original storage position.

<Effects of the first embodiment>
The storage device 1 uses the transport device 5 to transport the articles Z between the first article storage space R1 whose temperature is adjusted by the air curtain and the second article storage space R2 whose temperature is not adjusted. do. Therefore, the conveying device 5 can be positioned at a position facing both the storage position of the article Z in the first article storage space R1 and the storage position of the article Z in the second article storage space R2. Therefore, as in the configuration described in Patent Document 1, the storage position of the article Z in the first article storage space R1 and the storage position of the article Z in the second article storage space R2 are arranged horizontally, and these storage positions Compared to the configuration in which the transport device 5 is provided in front of the storage device 1, the transport space R3 for the articles Z can be made smaller, and the increase in size of the storage device 1 can be suppressed. In addition, the storage device 1 can be installed in a narrow space such as an aisle in a store.

The storage device 1 includes a freezer 22 that stores the goods Z at a freezing temperature, a cold storage 23 that stores the goods Z at a refrigerating temperature, and a normal temperature warehouse 24 that stores the goods Z at room temperature. Therefore, it is possible to provide the storage device 1 that can store the articles Z in three temperature zones and that can suppress an increase in size.

The freezer storage 22 is configured to be kept at a freezing temperature by closing the opening 22A with the second air curtain C2. In this way, by omitting a mechanical opening/closing mechanism for opening/closing the opening 22A of the freezer storage 22, there is no need to provide a heater or the like for preventing freezing of the mechanical opening/closing mechanism, thereby reducing power consumption. The storage temperature of the article Z can be maintained at an appropriate temperature while suppressing the temperature.

The refrigerating storage 23 is provided below the freezing storage 22, that is, downstream of the first and second air curtains C1 and C2 in the direction of air flow. The first air curtain generation unit 32 generates the first air curtain C1 so that the first air curtain C1 is positioned closer to the second article storage space R2 than the second air curtain C2. . Therefore, the first air curtain C1 can prevent the air in the second air curtain C2 having a temperature close to the freezing temperature from coming into contact with the air in the second article storage space R2 having a temperature close to the normal temperature. Inflow of moisture and heat into the warehouse 22 can be suppressed. As a result, the cooling load of the refrigerator 4 can be reduced. Further, since the first air curtain generating section 32 and the second air curtain generating section 31 are provided on the upper side of the housing 21, the first air curtain generating section 32 is separated from the freezer 22 and the refrigerator 23. and to generate the first and second air curtains C1 and C2 so that the positions of the first air curtain C1 and the second air curtain C2 in the front-rear direction are the same. In comparison, the housing 21 can be lowered.

The freezer storage 22 is configured such that a portion of the air forming the second air curtain C2 flows into the freezer storage 22 and is discharged from the through portion 222A of the back plate 222. Refrigerating storage 23 is configured such that part of the air forming first air curtain C 1 flows into refrigerating storage 23 and is discharged from back plate 232 through penetration portion 232A. Therefore, variations in the temperature inside the freezer storage 22 and inside the cold storage 23 can be suppressed.

The air of the second air curtain C2 that has passed in front of the freezer storage 22 flows through the second flow path 33 and returns to the second air curtain generator 31. Therefore, air having a temperature close to the freezing temperature can be caused to flow into the second air curtain generating section 31 . Therefore, it is possible to reduce the extent to which the temperature of the air in the second heat exchanger 417 decreases when the second air curtain C2 is generated.

The duct having the first flow path 34 is arranged between the duct having the second flow path 33 and the space on the rear side of the housing 21, and directs the air of the first air curtain C1 to the first air curtain. It is configured to be returned to the generator 32 . Therefore, the air of the second air curtain C2 having a temperature close to the freezing temperature can be prevented from coming into contact with the rear wall portion 214 of the housing 21, and the temperature rise of the air flowing into the second air curtain generator 31 can be suppressed. can.

The upper duct 321 forming the first duct D1 is arranged between the lower duct 311 forming the second duct D2 and the upper space of the housing 21 . In this way, by interposing the first cooling air A1 having a higher temperature than the second cooling air A2 between the air outside the housing 21 and the second cooling air A2, the second cooling air A rise in temperature of A2 can be suppressed.

A refrigerator 44 including a compressor 411 and a radiation heat exchanger 412 is provided above the second article storage space R2. A cooler 45 including first and

second heat exchangers

415 and 417 is provided above the first article storage space R1. In this way, the heat insulating material of the housing 21 can be thickened by providing the freezer 44 that reaches a high temperature at a position away from the first article storage space R1 in which the article Z is stored at the freezing temperature or the refrigerating temperature. Therefore, the temperature rise in the first article storage space R1 can be suppressed.

The second article storage space R2 is located closer to the opening 213A than the first article storage space R1. For this reason, for example, under operating conditions in summer, both the temperature and the absolute humidity of the air in the second article storage space R2 are higher than the cooled air in the first article storage space R1. The specific enthalpy difference between the ambient air taken into the storage device 1 as the opening 213A is opened and the air in the second article storage space R2 is greater than the specific enthalpy difference between the ambient air and the air in the first article storage space R1. become smaller. As a result, it is possible to suppress the temperature rise in the first article storage space R1 when the opening 213A is opened and the article Z is put in or taken out.

[Second embodiment]
Next, a second embodiment of the present disclosure will be described.

<Structure of storage device>
First, the configuration of the storage device will be described. FIG. 5 is a longitudinal sectional view of the storage device. FIG. 6 is a schematic diagram showing a fully closed state, a first half-open state, and a second half-open state of the partition.

A storage device 1A shown in FIG. 5 differs from the storage device 1 of the first embodiment in that it includes a partition portion 27A and a partition driving mechanism (not shown).

The partition section 27A includes a first door 271A and a second door 272A. The first and second doors 271A, 272A are supported by guides so as to be slidable in the horizontal direction. The first door 271A is provided in front of the second door 272A. The rear surface of the second door 272A is located closer to the second article storage space R2 than the front end of the upper duct 321 is. With such a configuration, it is possible to prevent the second door 272A from obstructing the flow of air through the first air curtain C1.

The partition drive mechanism moves the first and second doors 271A and 272A based on the control of the operation control unit, thereby setting the partition unit 27A to the fully closed state, the first half-open state, or the first half-open state shown in FIG. 2 to the half-open state. The fully closed state is an example of the first state. The first half-open state and the second half-open state are examples of the second state.

The fully closed state is a state in which the first article storage space R1 and the second article storage space R2 are separated. In the fully closed state, since the

openings

22A and 23A are entirely blocked by the partition 27A, the article Z cannot be put into or taken out of the freezer 22 or the refrigerator 23. FIG. The first half-open state is a state in which the left halves of the first article storage space R1 and the second article storage space R2 are partitioned and the right halves are not partitioned. In the first half-opened state, the left halves of the

openings

22A and 23A are closed by the partition 27A. can be done. The second half-open state is a state in which the right halves of the first article storage space R1 and the second article storage space R2 are partitioned and the left halves are not partitioned. In the second half-open state, since the right halves of the

openings

22A and 23A are closed by the partition 27A, the goods Z can be put into and taken out of only the left half area of the freezer 22 or the refrigerated storage 23. can be done.

<Operation of storage device>
Next, the operation of the storage device 1A will be described. The cooling operation in the freezer storage 22 and the cold storage 23 is the same as in the first embodiment, so the explanation is omitted. Also, the operation of loading and unloading the article Z will be described, focusing on the differences from the first embodiment.

The partition 27A is in a fully closed state when the goods Z are not being moved into or out of the warehouse. When the operation control unit determines a predetermined position in the freezer storage 22 or the refrigerated storage 23 as the storage position for the article Z based on the operation of the person entering the warehouse, the partition drive mechanism moves the transport space R3 to the determined storage position. The partition 27A is switched from the fully closed state to the first half-open state or the second half-open state so that the article Z can be taken in and out from the side. The article holding section 51 conveys the storage box 20 at the storage position determined by the operation control section to the placement section 262 of the loading/unloading section 26 . When the warehousing person puts the article Z into the storage box 20 placed on the placement section 262, the article holding section 51 returns the storage box 20 placed on the placement section 262 to the original storage position. When the storage box 20 containing the article Z is returned to the original storage position, the partition driving mechanism returns the partition section 27A to the fully closed state.

When the operation control unit specifies that a predetermined position in the freezer 22 or the refrigerated storage 23 is the storage position of the article Z based on the operation of the recipient, the partition driving mechanism controls the storage position specified by the operation control unit. The partition part 27A is switched from the fully closed state to the first half-open state or the second half-open state so that the article Z can be taken in and out from the transfer space R3 side. The article holding unit 51 transports the storage box 20 at the storage position specified by the operation control unit to the placing unit 262 of the loading/unloading unit 26 . The recipient takes out the article Z from the storage box 20 transported to the loading/unloading section 26 . When the warehousing person takes out the article Z from the storage box 20, the article holding section 51 returns the storage box 20 placed on the placement section 262 to the original storage position. When the storage box 20 from which the article Z has been taken out is returned to the original storage position, the partition drive mechanism returns the partition section 27A to the fully closed state.

<Effects of Second Embodiment>
The storage device 1A has a fully closed state that separates the entire range of the

openings

22A and 23A from the transfer space R3, a first half-open state that separates the left half of the

openings

22A and 23A from the transfer space R3, and an opening 22A. , 23A and a second half-open state for separating the transfer space R3 from the right half of the transfer space R3. Therefore, by fully closing the partitioning portion 27A in a state in which the goods Z are not being moved into and out of the warehouse, the partitioning portion 27A suppresses the air from the air curtain from flowing into the transfer space R3. It is possible to suppress the temperature rise of the freezer storage 22 and the cold storage 23 and the temperature drop of the normal temperature storage 24 . In particular, since the first air curtain C1 having a temperature higher than the refrigerating temperature is in contact with the partition 27A, even if the first and second doors 271A and 272A are made of metal or plastic with low heat insulation, the freezer storage can be maintained. 22 temperature rise can be suppressed. Moreover, it is not necessary to provide a heater or the like to prevent freezing of the partition driving mechanism.

[Modification of Embodiment]
It goes without saying that the present disclosure is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the present disclosure. Moreover, the above embodiments and modifications shown below may be combined in any way as long as they function normally.

For example, only the freezer 22 or the refrigerated storage 23 may be placed in the first article storage space R1. In the first article storage space R1, articles Z may be stored at three or more temperatures including a freezing temperature, a refrigerating temperature, and a temperature lower than the freezing temperature. Instead of the freezer 22 and the refrigerator 23, an article storage for storing the article Z at a heated temperature may be provided in the first article storage space R1.

The freezer 22 may not be provided with the penetration part 222A, and the cold storage 23 may not be provided with the penetration part 232A.

The opening 213A may be provided on the right side, left side, or rear side of the first item storage space R1, or on the right side or left side of the second item storage space R2.

Although the storage box 20 containing the article Z is placed in the freezer 22, the refrigerated storage 23, and the normal temperature storage 24, the article Z can be directly stored in the freezer 22 and the refrigerated storage without using the storage box 20. You may put it in the storage 23 and the normal temperature storage 24.

As shown in FIG. 7, the storage device 1, the storage device 1B, and the storage device 1C of the first embodiment may be connected in the horizontal direction to configure the article storage system 10. FIG. The storage device 1B connected to the right side of the storage device 1 differs from the storage device 1 in that it does not have the side wall portion 215, the opening 213A, the operation panel 25, the loading/unloading portion 26, and the article holding portion 51 on the left side. A storage device 1C connected to the left side of the storage device 1 includes a right side wall portion 215, an opening 213A, an operation panel 25, a loading/unloading portion 26, an air curtain generating device 3, a freezing device 4, and an article holding portion 51. First, it differs from the storage device 1 in that a room-temperature storage 24 is provided instead of the freezer 22 and the cold storage 23 . 7, illustration of the storage box 20 is omitted.

In such an article storage system 10, one article holding section 51 moves in the transport space R3 of the

storage apparatuses

1, 1B, 1C, and the freezer 22 or the refrigerator storage 23 of each of the

storage apparatuses
