Patent number: 11999068Abstract: A control device includes a first statistical processing unit a second statistical processing unit and a movement control unit. The first statistical processing unit acquires relative positions of the object calculated by the visual sensor and performs statistical processing on the acquired relative positions of the object. The second statistical processing unit acquires from the position sensor relative positions of the holding device corresponding to each of the relative positions of the object calculated by the visual sensor, and performs statistical processing on the acquired relative positions of the holding device. The movement control unit performs feedback control of the moving device based on the relative positions of the object and the relative positions of the holding, device and performs alignment of the object with the target position while moving the object closer to the target position.Type: GrantFiled: February 21, 2020Date of Patent: June 4, 2024Assignee: OMRON CORPORATIONInventors: Katsuyuki Kawamata, Kensuke Tarumi

Patent number: 10845776Abstract: A target path is corrected using an imaging result of a workpiece and a moving distance of a control object for each control cycle is kept constant. The PLC generates a connected path for each control cycle so that a length of the corrected path for each control cycle substantially matches a length of a normative path for each control cycle.Type: GrantFiled: June 12, 2018Date of Patent: November 24, 2020Assignee: OMRON CorporationInventor: Katsuyuki Kawamata

Patent number: 10572420Abstract: A control system synchronizes input timing and output timing between functional units, while achieving the contradictory aspect of shortening the communication cycle of data frames transferred on a network. An information processing apparatus calculates parameters for the functional units included in a slave device in accordance with a mode selected from a plurality of available modes. The modes include a first mode in which timing to obtain a status value from the control target and timing to update an output value for the control target are synchronized between all the functional units included in the slave device, and a second mode in which the timing to obtain a status value from the control target and the timing to update an output value for the control target are synchronized between specific functional units included in the slave device.Type: GrantFiled: November 24, 2015Date of Patent: February 25, 2020Assignee: OMRON CorporationInventors: Yoshimi Niwa, Takamasa Ueda, Katsuyuki Kawamata, Yuji Ikeo

Patent number: 9208011Abstract: A clock output unit outputs a synchronous clock signal. A serial data receiving unit receives data representing an absolute position and an encoder sends data in synchronization with the synchronous clock signal. A position conversion unit converts the received absolute position into a current position. The position conversion unit calculates a difference between a last received absolute position and an absolute position received immediately before the last received absolute position. The position conversion unit obtains the latest current position by adding the difference and a current position that was calculated immediately before the latest current position. If the absolute value of the calculated difference is greater than a threshold value, the position conversion unit determines that the last received absolute position has an error.Type: GrantFiled: March 4, 2014Date of Patent: December 8, 2015Assignee: OMRON CorporationInventors: Yoshimi Niwa, Katsuyuki Kawamata
