(Embodiment 1)
[Outline of logistics cycle]
First, the outline | summary of the physical distribution cycle using the transport box which the cooling apparatus which is Embodiment 1 of this invention makes the object of cooling is demonstrated. FIG. 1 is a schematic diagram showing an outline of a physical distribution cycle using a transport box targeted for cooling by the cooling apparatus according to the embodiment of the present invention. As shown in FIG. 1, between a plurality of distribution centers 110 to which products 101 are delivered and a store 120 that displays the products, the products 101 are stored in a plurality of transport boxes 1 that are reused by trucks 111. The transport box 1 that has been delivered to the store 120 and emptied is returned to the delivery center 110 by the truck 112. Note that the transport box 1 emptied at the store 120 may be returned to another distribution center 110.

  First, in the delivery center 110, the product 101 is delivered from the delivery source. The delivery center 110 receives the product 101 and sorts it by store. The sorted products 101 are stored in the transport box 1 sent to the delivery destination store 120. The inside of the transport box 1 is empty in the cold insulation heat space in which the product 101 is stored, and is kept at a desired temperature by the cold heat material. The truck 111 loads the transport box 1 storing the product 101 and delivers it to the delivery destination store 120. At the delivery destination store 120, the transport box 1 is unloaded from the truck 111, and the product 101 in the transport box 1 is taken out. The taken product 101 is displayed in a showcase or the like. The empty transport box 1 is temporarily held in the store 120. The delivered truck 111 loads the transport box 1 temporarily held as the truck 112 last time, and returns the transport box 1 to the distribution center 110.

  Here, the information collection device 30 is arranged in the store 120. The transport box 1 that is empty after the product 101 is taken out is communicatively connected to the information collecting device 30. The information collecting apparatus 30 sends the transport box history information such as the temperature history acquired by the transport box 1 at the time of delivery together with the transport box identification information to the upper information management apparatus 130 via the network N.

  On the other hand, the information collection device 30 and the cooling / heating device 40 are arranged in the distribution center 110. When the empty transport box 1 returned by the truck 112 is lowered from the truck 112, it is connected to the information collecting device 30 and the cooling / heating device 40. The information collection device 30 sends the transport box history information including the temperature history from when the product 101 is stored to the present to the upper information management device 130 via the network N together with the transport box identification information. The refrigeration apparatus 40 flows a chilled medium into the connected transport box 1 to store the refrigerated heat storage material in a cold state, and brings the cool heat storage space to a desired temperature. The empty transport box 1 set to the desired temperature is reused as the transport box 1 for delivering the product 101 again.

  The host information management device 130 connected to the network N uses the transport box history information and the transport box identification information sent from the information collection device 30 of the distribution center 110 or the store 120 to manage the temperature management state of the transported product 101. Analyze etc.

[Cooling device and transport box]
FIG. 2 is a block diagram showing a connection state and configuration between the cooling / heating device 40 and the transport box 1 in the distribution center 110. As shown in FIG. 2, the cooling / heating device 40 includes two cooling / heating units 40 a and 40 b and a control unit C, each of which is connected to a power source via a power cable 46. Each of the cooling / heating units 40a and 40b includes cooling / cooling circuits 41a and 41b and cooling / cooling control units 43a and 43b, respectively.

  The cooling / heating circuit 41a of the cooling / heating unit 40a is connected to the two transport boxes 1 via the cooling / heating pipes L2a and L2b and the pipe connector C2a, respectively. Further, the cooling / heating circuit 41b of the cooling / heating unit 40b is connected to the two transport boxes 1 via the cooling / heating pipes L2c and L2d and the pipe connector C2a, respectively.

  Each of the cooling / heating circuits 41a and 41b is a known refrigeration cycle apparatus including a compressor, a condenser, an expansion valve, an evaporator, and the like (not shown). The compressor (compressor) includes compressor motors 42a and 42b in the cooling circuits 41a and 41b. Each of the cooling circuits 41a and 41b, for example, rapidly cools the cooling medium to a desired temperature range under the control of the cooling control units 43a and 43b, and the rapidly cooled cooling medium is supplied to each of the cooling pipes L2a, L2b, It supplies to each cooler 21 of each carrying box 1 via L2c and L2d. Each cooling / heating pipe L2a, L2b, L2c, L2d is connected via a pipe connector C2b. Each cooler / heater 21 performs livestock cooling with respect to the regenerator heat material 22 by heat exchange between the cool medium and each cooler / heater material 22, and the cool heat storage space 23 is maintained at a desired temperature by each livestock cooler / heater 22. Each cooling circuit 41a, 41b is provided with a circulation pump (not shown) for circulating a cooling medium. The cold medium is a so-called brine medium such as water or antifreeze.

  A part of the control communication lines L3a, L3b, L3c, and L3d is integrated with each of the cooling pipes L2a, L2b, L2c, and L2d. The control communication lines L3a, L3b, L3c, and L3d are each connected to the control connector C3b on the transport box 1 side via the control connector C3a.

  Each of the cooling control units 43a and 43b has operation mode switches 44a and 44b. The operation mode is, for example, a cold heat treatment mode in which a cold medium is circulated to the cooler 21 by the cooler circuits 41a and 41b to cool the regenerator material 22 to cool the heat storage space 22 to a desired temperature, and the cooler 21 is maintained. This is a cooling medium recovery processing mode for recovering the cooling medium to perform the above. The operation mode switches 44a and 44b are slide switches that switch between ON and OFF, for example. When the operation mode switches 44a and 44b are OFF, the cooling heat treatment mode is selected and set. When the operation mode switches 44a and 44b are ON, the cooling medium recovery processing mode is selected and set. The operation mode switches 44a and 44b are preferably switches that are mechanically held in a selected state, such as slide switches. Therefore, the operation mode switches 44a and 44b may be rotary switches or seesaw switches. Further, the operation mode switches 44a and 44b may be multipoint switches instead of two points of ON and OFF. In the case of a multipoint switch, other processing modes can be selected and set.

  The controller C controls the cooling circuits 41a and 41b via the cooling control units 43a and 43b. Control communication lines L3a, L3b, L3c, and L3d are connected to the control unit C. For example, when the operation mode switches 44a and 44b are set in the cold heat treatment mode, the control unit C performs the cold heat treatment on the connected transport box 1, and the operation mode switches 44a and 44b are in the cold medium recovery processing mode. If it is set, the cold medium recovery process for the connected transport box 1 is executed. When performing this heat treatment, the control unit C connects based on the temperature information transmitted from the transport box 1 on the condition that one of the control communication lines L3a, L3b, L3c, and L3d is connected to the transport box. Control is performed to start the cold heat treatment via the cooler 21 so that the cold insulation heat space of the transport box 1 is in the desired temperature range. In addition, you may provide the control part C in each cooling-heat control part 43a, 43b separately.

  On the other hand, the transport box 1 is a heat insulating box body in which a cold heat storage space 23 for storing cold heat storage objects such as fresh foods and medicines is formed. The transport box 1 is provided with an open / close door 24 having heat insulating performance that opens and closes the front opening of the cold insulation heat space 23. Opening / closing of the open / close door 24 is detected by an open / close sensor 27. A plurality of temperature sensors 25 for detecting the temperature in the cold insulation heat space 23 are arranged in the cold insulation heat space 23. Further, a caster 28 is provided at the lower part of the transport box 1 to facilitate the transport of the transport box 1.

  The above-described cooler 21 and the regenerator material 22 are disposed in the heat insulation box. The cooler 21 cools / freezes or stores heat in the regenerator material 22. The chiller 21 has a metal pipe such as a copper pipe through which a chilling medium circulates in a meandering shape or a spiral shape and is in close contact with a flat inner surface such as a top wall or a side surface.

  The cold storage heat material 22 cools or stores heat in the box. The cold storage heat material 22 may be a known material in which water, a gelling agent, and the like are sealed in a resin case such as polyethylene, and is formed in a flat plate shape, for example.

  FIG. 3 is a cross-sectional view showing a cross-sectional structure of the heat insulating box. As shown in FIG. 3, a heat insulating material 51, a vacuum heat insulating material 52, a cooler / heater 21, a cold storage heat material 22, and a metal plate 53 are sequentially stacked from the outside of the box toward the inside of the box. The heat insulating material 51 is formed of, for example, foamed polystyrene or foamed urethane. As the vacuum heat insulating material 52, for example, a known material in which a core material is covered with a laminate film and the inside is reduced in vacuum to be sealed may be used. The vacuum heat insulating material 52 has extremely high heat insulating performance as compared with the general heat insulating materials such as the above-mentioned expanded polystyrene. The metal plate 53 defines the cold insulation heat space 23 and is disposed so as to contact the cold storage heat material 22. The metal plate 53 is formed of, for example, a stainless plate. Although not shown, it is preferable to provide a metal plate in which one surface is closely attached to the outer surface side of the regenerator material 22 and the other surface is closely attached to the inner surface side of the cooler 21. This metal plate is formed of a metal having a good thermal conductivity, for example, a plate material of aluminum or copper, and the cold heat from the cooler 21 can be efficiently transmitted to the cool storage heat material 22.

  The information management unit 10 of the transport box 1 is connected to the information collecting device 30 via the communication connector C1a and the communication line L1 including the power supply line. The communication connector C1a is connected to the communication connector C1b of the transport box 1. When the information management unit 10 is connected to the information collection device 30, the information management unit 10 charges the battery 11 via the power line. The information management unit 10 includes a control unit 13 and a storage unit 14. The control unit 13 sequentially holds the temperature history information that records the temperature detected by the temperature sensor 25 over time as one of the transport box history information 16, and the opening / closing history that records the open / closed state of the opening / closing sensor 27 over time. When information is held as one of the transport box history information 16 and the information collection device 30 is connected, the transport box identification information 15 and the stored transport box history information 16 are sent to the information collection device 30.

  Further, when the control connector C3a is connected to the control connector C3b, the control unit 13 transmits connection information indicating that the control communication lines L3a, L3b, L3c, and L3d are connected to the cooling / heating device 40 side. In addition, when the control connector C3a is connected to the control connector C3b, a structure for turning back an electrical signal to the control connector C3b side may be provided. In this case, even if the control unit 13 does not transmit connection information indicating that the control communication lines L3a, L3b, L3c, and L3d are connected to the cooling device 40 side, the control communication lines L3a and L3b on the cooling device 40 side. , L3c, L3d can be confirmed.

  Moreover, the control part 13 transmits the temperature information in the cold insulation heat | fever space 23 to the cooler 40 side via the control communication line L3a, L3b, L3c, L3d. Further, the control unit 13 performs control to open the solenoid valve 26 when the pipe connector C2a is connected to the pipe connector C2b, and close the solenoid valve 26 when the pipe connector C2a is removed.

  The transport box 1 has a display unit 12 such as an LED or a liquid crystal. For example, the control unit 13 lights the LED in green when the temperature in the cold insulation heat space 23 holds a desired temperature for a predetermined time. When the desired temperature is not maintained, the LED is lit red.

[Cooling control process by control unit C]
Here, with reference to the flowchart shown in FIG. 4, the cooling-heat control processing procedure by the control part C of this Embodiment 1 is demonstrated. As shown in FIG. 4, on the assumption that a power switch (not shown) is turned on, the control unit C first determines that the control connector C3a is a control connector based on connection information transmitted from the transport box 1 side. It is determined whether it is connected to C3b, that is, it is ON (step S101). Note that the connection information transmitted from the transport box 1 side may be whether or not the return signal is received by the control connector C3b. When the control connector C3a is ON (step S101, Yes), the control unit C, based on the received temperature information, passes through the cooling control units 43a and 43b so that the cold insulation heat space 23 is in a desired temperature range. Then, the cooling circuits 41a and 41b are driven to perform a control for starting the cooling heat treatment via the cooling device 21 (step S102), and this processing is finished. On the other hand, if the control connector C3a is not ON (step S101, No), this determination process is repeated.

  In the first embodiment, on the condition that the control communication lines L3a, L3b, L3c, and L3d are connected to the transport box 1, the cold heat treatment via the cooler 21 is performed so that the cold insulation heat space 23 becomes a desired temperature range. Control to start is performed. Therefore, since optimal cooling control is performed using the temperature information received from the transport box 1 side, a short cooling period is sufficient and the occurrence of a cooling failure or the like can be prevented. Moreover, the state of the refrigerator 21 etc. can be managed.

(Embodiment 2)
In the second embodiment, when cooling control is performed by the control unit C, the cooling heat treatment is started on the condition that the opening / closing door 24 of the cold insulation heat space 23 is closed.

[Cooling control process by control unit C]
FIG. 5 is a flowchart illustrating a cooling control process procedure by the control unit C according to the second embodiment. As shown in FIG. 5, the control unit C assumes that a power switch (not shown) is turned on. First, based on connection information transmitted from the transport box 1, the control connector C3a is turned on. It is determined whether or not there is (step S201). When the control connector C3a is ON (step S201, Yes), it is further determined whether or not the open / close sensor 27 detects the close (step S202). When the open / close sensor 27 detects the close (step S202, Yes), the control unit C, based on the received temperature information, the cooling control unit 43a, The cooling circuits 41a and 41b are driven through 43b, and the control for starting the cooling heat treatment through the cooling device 21 is performed (step S203), and this processing is finished. On the other hand, when the control connector C3a is not ON (step S201, No) and when the open / close sensor 27 is not detected to be closed (step S202, No), the process proceeds to step S201 and the above-described processing is repeated.

  In the second embodiment, on the condition that the control communication lines L3a, L3b, L3c, and L3d are connected to the transport box 1 and the open / close door 24 is closed, the cold insulation heat space 23 is in a desired temperature range. In addition, control for starting the cooling heat treatment via the cooler 21 is performed. Therefore, since optimal cooling control is performed using the temperature information received from the transport box 1 side, a short cooling period is sufficient and the occurrence of a cooling failure or the like can be prevented. In particular, since the cooling control is not performed with the open / close door 24 open, wasteful power consumption can be suppressed and the occurrence of a cooling failure or the like can be prevented. Moreover, the state of the refrigerator 21 etc. can be managed.
