Embodiment

[0028] Figure 1~Figure 8 Examples and modifications thereof are shown. Figure 1~Figure 3 Representing the initial embodiment, 2 in the figure is an automatic warehouse for a clean room, for example, a pair of left and right shelves 4, 4 are provided, and the shelves are divided into a plurality of warehouse openings 6 along the length direction and the up and down direction of the automatic warehouse 2 . For example, a ventilation space 8 is provided on the back of the shelves 4 , 4 , for example, a fan filter unit (FFU) 9 is provided at each bin 6 . exist figure 2 In , although it is shown that one FFU9 is provided at each port, multiple FFU9s may be provided at each port 6, or one FFU9 may be provided with respect to a plurality of port 6. In the case of picking and unloading items such as boxes 18 from the back of the hatch 6, the FFU 9 is provided, for example, on the side, upper surface, etc. of the hatch. A shelf support 20 is provided at each port 6 to support th...

Abstract

The present invention provides an automatic warehouse for a clean room, which can reduce power consumption of a fan filtering unit through simple control. The automatic warehouse for the clean room is provided with the following components: shelves; a plurality of fan filtering units which blast clean air to openings of the shelves; an in-warehouse conveying device; and a controller which controls the fan filtering units and the in-warehouse conveying device. The controller divide each shelf to a clean area which comprises warehouse entering positions of the objects and an energy saving area, thereby controlling the plurality of fan filtering units in a manner of larger blast volume of the clean air than the clean area.

Description

technical field [0001] The present invention relates to an automated warehouse for clean rooms. Background technique [0002] In automatic warehouses for clean rooms, fan filter units are installed on the back of the shelves, etc., to supply clean air to the warehouse opening. The supply of clean air requires a large amount of power, and in order to reduce operating costs and CO 2 Discharge volume, need to reduce power consumption. Here, if referring to related prior art, Patent Document 1: JP2009-184794A discloses that the supply amount of clean air is changed according to the speed of a stacker crane. However, only the rotation speed of the fan in the fan filter unit can be slowed down, and it is difficult to change the rotation speed following the speed of the stacking crane. Therefore, it is necessary to reduce the power consumption of the fan filter unit through simpler control. [0003] Patent Document 1: JP2009-184794A Contents of the invention [0004] The sub...
