Patent number: 9592965Abstract: A conveying apparatus that increases the conveying speed of a conveyance object, and improves reliability and conveyance efficiency at low cost. Acceleration/deceleration sections, each of which includes a plurality of variable-speed conveyance sections, are provided among constant-speed conveyance sections. The conveying speed of a conveyance object is continuously accelerated or decelerated while the conveyance object passes through the acceleration/deceleration sections. This changes the conveying speed from the conveying speed of the upstream constant-speed conveyance section to the conveying speed of the downstream constant-speed conveyance section. Thus, it is controlled that the conveying speed and the conveyance acceleration/deceleration is identical between the upstream conveyance section and the downstream conveyance section when the conveyance object is transferred from the upstream conveyance section to the downstream conveyance section.Type: GrantFiled: March 15, 2016Date of Patent: March 14, 2017Assignee: Daifuku Co., Ltd.Inventors: Kazushi Tsujimoto, Shinji Inatomi

Patent number: 8607911Abstract: A movable rack system able to carry out a widthwise shift control of a movable rack without using a sheet rail member to be detected. The system is so configured, that magnets are placed at stop positions of the movable rack on the floor surface as members to be detected, while the movable rack is equipped with magnetic sensors to detect the magnets. When the movable rack stops traveling, the magnetic sensors detect the magnets and compares the detected magnetic intensity to the magnetic intensity detected at the previous stop. If the change exceeds a pre-determined value, namely the widthwise shift exceeding a pre-determined value is detected, a travel route of the movable rack to eliminate the widthwise shift is determined. In the next travel of the movable rack the rotation speeds of the respective driving motors are controlled so that the movable rack follows the travel route.Type: GrantFiled: March 27, 2009Date of Patent: December 17, 2013Assignee: Daifuku Co., Ltd.Inventors: Kazushi Tsujimoto, Natsuo Takagawa, Syouji Yokoyama
