Further, the air delivery capacity of the cooling coil is several times that of the blower fan 46 disposed in the duct 45.

  A lighting device 72 is disposed outside the lower end of the outer duct 49. The illuminating device 72 is, for example, a fluorescent lamp, and is turned on during operation of the freezer / refrigeration picking system, and can be turned off when the operation is stopped.

  The lighting device 72 is covered with an umbrella 73. A switch (not shown) for turning on or off the lighting device 72 is provided on the front surface of the umbrella body 73. This switch is interlocked with the outer fan 496, and the outer fan 496 is driven when the lighting device 72 is turned on, and the outer fan 496 is stopped when the lighting device 72 is turned off.

  In addition, this switch gives an instruction signal to a temperature adjustment device that adjusts the internal temperature of the freezing / refrigeration warehouse 2 for picking. For example, when the lighting device 72 is turned on, an instruction is given to set the set temperature to -18 degrees Celsius, and when the lighting device 72 is turned off, an instruction is given to set the set temperature to -15 degrees Celsius. .

  When the refrigerant is supplied from the refrigerator to the evaporator 471 in the freezing / refrigeration warehouse 2 for picking, the refrigerant evaporates in the evaporator 471 and cools the air around the evaporator 471.

  In addition, when the cooling coil (cooling device), the blower fan (blower device) 46, the intake fan 52, the circulation fan, and the outer fan 496 are operated, the air that has passed around the cooling coil is cooled to about -25 degrees Celsius, It is sent out toward a vertical wall (step) provided between the storage display area (front area) 4 and the storage conveyance area (rear area) 6. The delivered air is diffused by colliding with a vertical wall (step) provided between the storage display area (front area) 4 and the storage conveyance area (rear area) 6, and is blown from the cooling coil to the blower fan. Compared with the case where air is sent directly to 46, the flow velocity of air becomes slower, and air is evenly supplied to the blower fan 46.

  The air supplied to the blower fan 46 is distributed to the inner duct 47 and the middle duct 48. The air distributed to the inner duct 47 is cooled to about -30 degrees Celsius when passing around the evaporator (evaporator) 471, and flows from the front end opening toward the return grill, whereby the freezer / refrigeration warehouse 2 for picking is used. An air curtain of about -30 degrees Celsius is generated inside the front opening. On the other hand, the air distributed to the middle duct 48 flows from the front end opening toward the return grill 50, thereby generating an air curtain of about −25 degrees Celsius outside the air curtain generated by the inner duct 47.

  On the other hand, by operating the outer fan 496, the air introduced from the building of the distribution center flows along the air curtain described above, and suppresses the turbulence of the air that generates the air curtain.

  On the other hand, the air collected from the return grill 50 is sent to the back by the intake fan 52 and the circulation fan and circulates along the back wall. And the air which circulated along the back wall is supplied to a cooling coil again.

  The air thus circulated and cooled by the cooling coil and the evaporator (evaporator) 471 cools the inside of the freezing / refrigeration warehouse 2 for picking.

  Moreover, goods are carried in from the outside to the freezing / refrigeration warehouse 2 for picking by a goods carrying-in conveyor. The goods carried into the freezing / refrigeration warehouse 2 for picking are temporarily stored in the goods temporary storage shelf, or are put into the slant flow shelf 42 of the display / picking unit 41 by the goods loading / conveying device. Note that the products temporarily stored in the temporary product storage shelf are sequentially put into the slanted flow shelf 42 of the display / picking unit 41 by the product input / conveyance device when the order comes.

  Further, the picking refrigerator / freezer warehouse 2 is controlled by the management device, and the LED display panel 43 at the storage position where the product to be taken out is stored is turned on. Then, the operator identifies whether or not the storage position indicated by the lit LED display panel 43 is a shelf handled, and if the operator identifies that the shelf is a ledge handled by the operator, the storage position indicated by the lit LED display panel 43 is determined. The product will be taken out from.
