Patent number: 11164303Abstract: Provided is an inspection system that can reduce the burden of inspecting a detector provided on a transport vehicle that travels on a preset transport path. An inspection system 1 includes a projection surface 5F that is disposed at a position located within a detection range IE of a detector 3 in a state in which a transport vehicle 2 is present at an inspection location IP set on a transport path R, and onto which detection light IL projected by the detector 3 is projected, an image capturing device C that captures an image of the projection surface 5F, and a determination unit that determines at least one state selected from a position, a shape, and a light intensity of the detection light IL projected onto the projection surface 5F, based on an image captured by the image capturing device C.Type: GrantFiled: February 4, 2020Date of Patent: November 2, 2021Assignee: Daifuku Co., Ltd.Inventors: Daisuke Ogawa, Tsubasa Yajima

Patent number: 10699925Abstract: Regarding a transfer system that includes a plurality of transfer vehicles that transfer articles, the present invention realizes technology that can alleviate congestion that is caused due to the travel speed of a specific vehicle that performs a specific task being lower than that of the transfer vehicles. The transfer system includes a plurality of transfer vehicles that travel on a transfer path to transfer articles, and the transfer system further includes: a specific vehicle that performs a specific task while travelling on the transfer path at a speed lower than that of the transfer vehicles; and a congestion determination unit that determines whether or not there is congestion behind the specific vehicle. Upon the congestion determination unit determining that there is congestion, the specific vehicle suspends the task and performs evacuation travel to evacuate from a task point at which the specific vehicle was performing the task.Type: GrantFiled: October 10, 2018Date of Patent: June 30, 2020Assignee: Daifuku Co., Ltd.Inventors: Daisuke Ogawa, Tsubasa Yajima, Masahiro Takahara, Tomoaki Nishikawa
