2. Description of the Related Art For example, in the case of tangerines, so-called coloring (preparation) processing, which is heated to about 40 ° C. before shipping and stored and aged in an atmosphere containing ethylene gas for a required period, is performed. It is known to do. On the other hand, when fruits and fresh vegetables are stored for a long period of time, it is also known that the temperature of the atmosphere is lowered, and if necessary, a gas that suppresses respiration is mixed in, and stored in a so-called hibernation state. Have been.

[0003] In order to store fruits and fresh vegetables, it is essential to adjust the atmosphere.
When using a ventilated container to perform an automatic warehouse that can automatically perform entry and exit operations mechanically, that is, an automatic warehouse that has shelves and traveling cranes for entry and exit, the atmosphere of the large space in the warehouse is reduced. Even if the air conditioner adjusts the storage according to the purpose of storage and also uses a means for forcibly circulating the atmosphere in the warehouse, the atmosphere is surely passed through the container stored in the shelf, It is almost impossible to make the atmosphere evenly contact the fruits and the like.

[0004] In other words, it is practically impossible to utilize the automatic warehouse as described above for storing fruits and fresh vegetables whose atmosphere needs to be adjusted. It was usual to use a room.

Each of the shielding walls 13 and 14 can be formed by stretching a flexible sheet such as vinyl, in addition to a hard plate made of metal, wood, plastic, or the like. In this embodiment, the shielding wall 12 on the back side is formed by stretching the above-mentioned sheet.

The curtain 15 is suspended by a guide rail 16 erected above the front side of the shelf 3 and is moved horizontally along the crane travel path 4 to open and close. In a state corresponding to each of the load storage sections 11, a net-shaped material 17 is stretched and a rectangular ventilation portion 19 vertically connected by a reinforcing hanging strip 18 is formed. The curtain 15 is mounted on the shelf 3 as shown in FIG.
End (opposite side of crane 5 home position side)
Is folded and stored in a curtain storage section 20 provided adjacent to the crane traveling path direction.

That is, as shown in FIG. 4, hanging members 21 attached to the upper end of the curtain 15 at equal intervals are slidably engaged with the guide rails 16, and the leading hanging member 21a
Is locked by a curtain opening / closing drive cable 22 hung along the guide rail 16, and by rotating the curtain opening / closing drive cable 22 in the curtain pull-out direction, the curtain opening / closing drive cable 22 is sequentially moved from the leading end side to the curtain storage section 20. It is pulled out and shields the front of the shelf 3, and the curtain opening / closing drive cable 22 is rotated in the curtain storage direction in the reverse direction to be sequentially folded in a zigzag shape from the front side and stored in the curtain storage section 20. Reference numerals 23a to 23d denote guide wheels for hanging the curtain opening / closing drive rope 22, and reference numeral 24 denotes a motor with a speed reducer for driving one guide wheel 23a to rotate forward and reverse through a chain transmission means 25.

Reference numeral 26 denotes an atmosphere forced circulation means, which comprises an air intake duct 27 with a fan and an air supply duct 28. The intake duct 27 with a fan is disposed on the back side of the shelf 3, and the intake duct 29 connected to the opening provided corresponding to each load storage unit 11 on the shielding wall 12 on the back side of the shelf 3. Have. In addition, the shielding wall 12 on the back side of the shelf 3 may be shared by the intake duct 27 with a fan. The fan-equipped intake duct 27 can be configured so as to be continuous over the entire length of the shelf 3. However, as shown in FIG. Motor drive fan 30 for each 27
It is desirable to arrange. This motor drive fan 30
Although the air conditioner is disposed in a direction of sending air toward the ceiling, it may be disposed laterally in a direction in which the air conditioner 32 is located.

The air supply duct 28 is disposed along the crane traveling path at the lowermost part of the shelf 3, that is, below the shielding wall 14 on the bottom side of the shelf 3, and is an air supply opening opened on the crane traveling path 4 side. 31 and as shown in FIG.
Inside, the adjusted atmosphere sent from the air conditioner 32 installed on the side opposite to the home position side of the crane 5 is distributed to the lower part of the crane traveling passage. The air supply duct 28 can also serve as the bottom-side shield wall 14 of the shelf 3.

At the side of the crane 5 at the home position, there are provided an incoming conveyor 33 for carrying in the container C and an outgoing conveyor 34 for carrying out the container C. Reference numeral 35 denotes an entrance provided with a door 36.

In the automatic warehouse having the above configuration, when the air conditioner 32 and the motor drive fan 30 of the air intake duct 27 with the fan are operated in a state where the front of the shelf 3 is shielded by the curtain 15, the temperature is adjusted by the air conditioner 32 and The air in the closed space 1 to which necessary gas is added as required, that is, the adjusted atmosphere is supplied to the air supply duct 28 below the shelf, and from the air supply port 31 of the air supply duct 28 to the lower part in the crane traveling passage 4. Sent to At this time, since the inside of the shelf 3 is at a negative pressure due to the suction action of the motor drive fan 30 of the suction duct 27 with a fan, the adjusted atmosphere sent to the lower part of the crane traveling passage 4 is transmitted from the respective ventilation portions 19 of the curtain 15. The air enters the load storage unit 11 of the shelf 3 and is sucked into the air intake duct 27 with a fan from the air inlet 29 on the rear side of the shelf 3. Then, the air is sent toward the ceiling in the closed space 1 by the motor drive fan 30. By the above-mentioned operation, the atmosphere in the closed space 1 is forcibly circulated and flowed in the closed space 1 in a state adjusted by the air conditioner 32. The adjustment atmosphere flows individually from the front side to the back side in the inside of the chamber 11.

Accordingly, by storing the permeable container C containing fruits and fresh vegetables in each load storage section 11 of the shelf 3 by the traveling crane 5 for loading and unloading, using a conventionally well-known method. The crane traveling passage 4 in the load storage unit 11
The adjusted atmosphere flowing from the side to the back side passes through the container C and comes into contact with stored fruits and the like, and the desired action of the adjusted atmosphere on the fruits and the like, for example, a coloring action by warm air and ethylene gas is performed.

A container C containing fruits and the like
Means that the front (the crane traveling passage 4 side) is a curtain 15
It is desirable to support the load-bearing arm 10 in the load storage unit 11 at a position where it comes into contact with the arm. In addition, if there is an empty load storage unit 11 in which the container C is not stored, the atmosphere tends to concentrate and flow at that location. It is preferable that an empty container having no air permeability is stored in the load storage unit 11 so that the atmosphere is prevented from flowing in the load storage unit 11 as much as possible. Of course, as the container C for storing fruits and the like, it is desirable that only the front and rear side walls have air permeability and the left and right side walls and the bottom have no air permeability.

Container C by the traveling crane 5 for loading and unloading
The curtain 15 is opened at the time of the loading / unloading operation of the above.
That is, the curtain 15 is folded in a zigzag shape and stored in the curtain storage section 20 by reversing the curtain opening / closing drive cable 22 in the curtain storage direction by the motor 24 with a speed reducer shown in FIG. In this way, the crane traveling passage 4 side of the shelf 3 is opened, and the container C is transferred to the load storage unit 11 by the lifting carriage 8 of the crane 5 and the transfer means 9 such as a running fork. You can transfer the goods from In this case, it is possible to open only the curtain 15 of the shelf 3 to be moved in and out. In addition, during the loading / unloading operation, the air conditioner 32 and the motor drive fan 30 of the intake duct 27 with a fan can be stopped.

The air supply duct 28 serves to distribute the conditioned atmosphere to the entire area inside the crane travel path 4.
When the crane traveling passage 4 (the length of the shelf 3) is relatively short, the air supply duct 28 may not be basically provided. In this case, the adjusted atmosphere is supplied from the air conditioner 32 to the crane traveling passage 4.
What is necessary is just to feed inside from one end. Further, even when the air supply duct 28 is used in combination, the air supply duct 28 may be provided, for example, on the ceiling of the crane travel path 4 to send out the adjusted atmosphere downward.

The periphery of the shelf 3 except for the front side is a shielding wall 1.
The air inlet 2 in the air intake duct 27 with a fan of the atmosphere forced circulation means 26 is enclosed by
9 is opened, but the shielding walls 12 to 14 are basically unnecessary, and the ventilation section 19 of the curtain 15 and the intake port 29 of the intake duct 27 with a fan are arranged before and after each load storage section 11 of the shelf 3. By doing so, it is possible to create a flow of an atmosphere that flows across the inside of the load storage unit 11.

The openable and closable curtain for shielding the front side of the shelf 3 is a vertically moving curtain 3 as shown in FIG.
7 can also be set. In this case, a curtain storage section 38 is provided at the upper portion of the shelf 3 for winding and storing the curtain 37. Reference numeral 39 denotes a curtain winding drum, which is driven by a motor 40 to rotate forward and backward. Of course, a motor-driven curtain opening / closing drive cable that forcibly raises / lowers the curtain 37 may be used in combination.

The openable and closable curtain 15 (or curtain 37) for shielding the front side of the shelf 3 can be divided into a plurality of pieces in the direction of the crane traveling passage and can be individually opened and closed. In this case, as shown in FIGS. 1 to 4, the curtain 15 that opens and closes and moves horizontally along the crane traveling path 4.
6, the shelf 3 can also be divided for each curtain 15, and a curtain storage section 20 can be provided at one end of each shelf 3, as shown in FIG. The air supply duct 28 can be continuously integrated without being divided.
