JP-A-2015-040122A

In such a picking facility, it is conceivable to include a picking unit for picking work by an operator in addition to a picking unit for picking work by a transfer robot. By increasing the number of such picking units, it is possible to increase the number of picking operations that can be performed in parallel. However, depending on the location conditions of the picking equipment, the space for arranging many picking parts may be limited.

Therefore, it is desired to realize a picking facility that can easily secure the degree of freedom in the arrangement of each device when many picking portions are provided.

In view of the above, the characteristic configuration of the picking equipment is installed in one building, and includes a first picking unit in which the transfer robot performs the picking work and a second picking unit in which the operator performs the picking work. The first picking unit includes, as the transfer robot, a lower layer transfer robot and an upper layer transfer robot arranged above the lower layer transfer robot, and the first lower layer in which the lower layer transfer robot performs picking work. The building is provided with a first lower layer conveyor that conveys articles to the picking section and a first upper layer conveyor that conveys articles to the first upper layer picking section where the upper layer transfer robot performs picking work. A lower floor portion where the robot can walk and an upper floor portion which is installed above the lower floor portion and where the worker can walk are provided, and the second picking portion is above the lower floor portion. A second lower layer conveyor that conveys an article to a second lower layer picking section where the worker performs picking work, and a second upper layer picking section that conveys the article to a second upper layer picking section where the worker performs picking work on the upper floor portion. The loading device provided with the two upper layer conveyors and carrying articles into each of the first lower layer conveyor, the first upper layer conveyor, the second lower layer conveyor, and the second upper layer conveyor is common to these four conveyors. The first upper layer conveyor is installed above the first lower layer conveyor, the second upper layer conveyor is installed above the second lower layer conveyor, and the lower layer transfer robot and the robot are provided. The upper layer transfer robot, the first lower layer conveyor, and the first upper layer conveyor are supported by a reference floor provided in the building, and the lower floor portion and the upper floor portion are supported by the building. At least a part of the second lower layer conveyor is supported by the lower floor portion, and at least a part of the second upper layer conveyor is supported by the upper floor portion.

According to this feature configuration, since the upper layer transfer robot is arranged above the lower layer transfer robot, it is not necessary to arrange the upper layer transfer robot and the lower layer transfer robot so as not to overlap each other in the vertical direction. Further, since the first upper layer conveyor is arranged above the first lower layer conveyor, it is not necessary to arrange the first upper layer conveyor and the first lower layer conveyor so as not to overlap each other in the vertical direction. Therefore, the degree of freedom of these arrangements can be increased. Therefore, for example, by shifting these arrangement spaces in the vertical direction and overlapping them in a plan view, it is possible to reduce these arrangement spaces in the horizontal direction. Further, since the lower layer transfer robot, the upper layer transfer robot, the first lower layer conveyor, and the first upper layer conveyor are supported by the same reference floor provided in the building, the lower layer transfer robot, the upper layer transfer robot, the first lower layer conveyor, and the first upper layer conveyor are supported by the same reference floor provided in the building. The configuration is simplified as compared with the configuration in which the upper floor portion is installed, the lower layer transfer robot and the first lower layer conveyor are supported by the lower floor portion, and the upper layer transfer robot and the first upper layer conveyor are supported by the upper floor portion. At the same time, it becomes easy to keep the installation space in the vertical direction of the equipment small.

On the other hand, according to this configuration, the worker performs the picking work on the lower floor portion or the upper floor portion. Since these lower floors and upper floors are floors provided in the building, picking work can be performed in a more stable state than when working on a stand or the like separately installed on the reference floor. This makes it easier for workers to perform picking work. Further, these lower floors and upper floors can be small floors because it is not necessary to support the lower transfer robot, the upper transfer robot, the first lower layer conveyor, and the first upper layer conveyor. Therefore, when installing the lower layer transfer robot, the upper layer transfer robot, the first lower layer conveyor, and the first upper layer conveyor, the lower layer floor portion and the upper layer floor portion are less likely to get in the way, and the arrangement is free when these are installed. The degree can be increased.
