2. Description of the Related Art Conventionally, when a packing box in which the above-mentioned products are packed in a box is stored until the time of shipment, for example, a large number of packing boxes brought in from a producer side are sorted and sorted by product type and grade. After stacking a predetermined number of boxes on the pallet, the pallets are sequentially loaded into a cold storage warehouse cooled to a predetermined storage temperature (for example, about 5 ° C.) and stored until shipping, and the cooling means is driven. The cool air in the cold storage is circulated to cool each packing box stacked on the pallet. At the time of shipping, pallets in which a predetermined number of boxes are stacked are sequentially loaded from a cold storage warehouse and are shipped by type and class.

However, as described above, since a predetermined number of boxes are loaded or unloaded while being stacked on the pallet, if the pallet is loaded without stopping the cooling means, Because of the circulation of cold air inside the cold storage warehouse, the outside warm air is actively sucked in on this circulating airflow, and the internal temperature of the entire cold storage warehouse rapidly rises above the predetermined storage temperature of the cargo, The product packed in the packing box ripens early by self-breathing, and the freshness of the product is impaired by the time of shipment. Therefore, it is necessary to rapidly cool the atmosphere in the cold storage warehouse with cooling means to keep the atmosphere in the warehouse cool at a predetermined temperature.However, since the temperature rise due to the inflow of warm air is greater, the atmosphere in the warehouse must be maintained at a predetermined temperature. It takes a long time to cool to the storage temperature of
Since the temperature inside the cold storage warehouse is higher than the storage temperature, there is a problem that it is not a solution for decreasing freshness.

According to the present invention, when loading or unloading a predetermined number of boxes into or out of any one of the divided storage chambers constituting the load storage chamber, the cooling means of the divided storage chamber is stopped. And
The shutter provided on the entrance side of the divided storage chamber is opened, and each cargo box carried in by the loading conveyer is sequentially transferred onto each of the cargo storage conveyors inside the same compartment. Alternatively, the shutter provided on the exit side of the divided storage chamber is opened, and each of the boxes placed on each of the load storage conveyors in the same chamber is sequentially transferred to the loading conveyor and unloaded. Warm outdoor air can be prevented from being sucked into the divided storage chamber. In addition, when loading or unloading a cargo box into or from one divided storage chamber, each divided storage chamber is not affected by outside air because it is kept cool by cooling means with shutters provided in the other divided storage chambers closed. The storage room is maintained at a predetermined load storage temperature. Thereafter, the cooling unit is loaded or unloaded with a predetermined number of boxes to any one of the divided storage chambers constituting the load storage room, and then the cooling unit of the divided storage room is driven. Since each cargo box placed on each cargo storage conveyor in the same room is cooled, the room temperature in each of the divided storage chambers constituting the cargo storage room can be constantly kept at a predetermined cargo storage temperature.

According to the present invention, any one of the cooling means in each of the divided storage chambers constituting the load storage chamber is stopped, and each of the divided storage chambers has a predetermined number of boxes in which the product is packed. Since the packing boxes are loaded or unloaded, warm air outside the room can be prevented from being sucked into the divided storage chambers, and a predetermined number of boxes are loaded or unloaded into the plurality of divided storage chambers. Therefore, it is only necessary to cool the atmosphere in the divided storage room where the room temperature has risen by the cooling means, and the atmosphere in the divided storage room is rapidly cooled in a short time so that the room temperature in each of the divided storage rooms constituting the load storage room is reduced to a predetermined value. It can always be kept cool at the storage temperature. In addition, since each divided storage room is kept cool at an appropriate temperature at the same time, the room temperature in each divided storage room is kept cool to a temperature at which ripening of the product by self-respiration stops, and during the storage period, the product is kept cool. It is possible to positively prevent the freshness from being impaired.

When a predetermined number of boxes A are stored in the divided storage chambers 3a and 3b constituting the load storage chamber 3 as described above, the circulation provided in the divided storage chambers 3a and 3b is provided. The driving of the blower 19 and the refrigerating device 21 is stopped to load or unload a predetermined number of packing boxes A in which the products are packed into these divided storage chambers 3a and 3b. Since it is possible to prevent the outside warm air from being sucked into the chambers 3a and 3b, and to carry in or carry out a predetermined number of boxes A to each of the divided storage chambers 3a and 3b.
It is only necessary to cool the atmosphere in each of the divided storage chambers 3a and 3b whose room temperature has risen, and the atmosphere in each of the divided storage chambers 3a and 3b is rapidly cooled in a short time, so that each of the divided storage chambers 3 is constituted. The room temperature in the storage chambers 3a and 3b can always be kept at a predetermined storage temperature. Moreover, when a predetermined number of boxes A are loaded or unloaded to or from one of the divided storage chambers 3b, the room temperature in the other divided storage chamber 3a is kept at an appropriate temperature. Each divided storage room 3a, 3b
By keeping the room temperature at a temperature at which ripening of the product by self-respiration stops, freshness of the product during storage can be positively prevented from being impaired.
