Patent number: 10836035Abstract: A drive control device activates at least one of a plurality of operation regions and restricts operations by a robot such that the robot operates within the activated operation region. With a plurality of operation regions such as an operation region 1 and an operation region 2 being activated, when the drive control device predicts that the robot will be included in a range of any of the operation region 1 and the operation region 2, the drive control device does not cut off supply of electric power to a servo amplifier, whereas when the drive control device predicts that the robot will be included in a range of neither of the operation region 1 and the operation region 2, the drive control device cuts off supply of electric power to the servo amplifier.Type: GrantFiled: October 7, 2015Date of Patent: November 17, 2020Assignee: OKURA YUSOKI KABUSHIKI KAISHAInventors: Hideki Sawada, Toshiyuki Sato, Tatsuo Onoyama, Ryoichi Okura, Mugen Kawazu

Publication number: 20200254631Abstract: An abnormal condition determination system includes a detection device which detects rotation of each rotation shaft of a robot and an abnormal condition determination device which detects an encoder abnormal condition based on an absolute signal and an incremental signal from the detection device. The abnormal condition determination device calculates an absolute angle of the rotation shaft based on an amount of variation in angle of rotation of the rotation shaft indicated by an incremental signal from an incremental encoder. The abnormal condition determination device determines the detection device as abnormal when a difference between the absolute angle of the rotation shaft calculated based on the incremental signal and the absolute angle of the rotation shaft indicated by the absolute signal from an absolute encoder is out of an allowable range.Type: ApplicationFiled: November 12, 2015Publication date: August 13, 2020Inventors: Hideki Sawada, Toshiyuki Sato, Tatsuo Onoyama, Ryoichi Okura, Mugen Kawazu

Publication number: 20070272357Abstract: A plurality of liquid chemicals are fed onto a substrate to be treated, which is held and spinned, and the liquid chemicals scattered from the substrate to be treated by a rotator are separately recovered in respective recovery tanks (16 to 19) by each chemical. A lifting mechanism controls lifting operation of respective fences (3a to 3s) which form respective recovery tanks (16 to 19) so as to recover the liquid chemical into a certain recovery tank, while at the time, inlets of the other recovery tanks are closed at that time. Such a lifting mechanism includes a fence lifting plate provided with a cams portions 29a engaging with the respective fences (3a to 3d) to lift the corresponding fence, and performs lifting operation of the respective fences (3a to 3d) by rotating the fence lifting plate (29) around the shaft of the fence lifting plate (29) by a motor (34) so that the liquid chemical to be recovered is prevented from mixing in other recovery tanks.Type: ApplicationFiled: March 7, 2005Publication date: November 29, 2007Applicant: SIPEC CORPORATIONInventors: Tamio Endo, Ryoichi Okura, Tatsuro Yoshida, Yoshishige Takikawa

Patent number: 5829939Abstract: A treatment apparatus comprises a treatment chamber for performing a treatment for a workpiece W, a loading chamber connected to the treatment chamber, for loading and unloading a holding member which contains the workpiece into and from the treatment chamber, and an input/output chamber for inputting and outputting the workpiece to and from the loading chamber. The input/output chamber includes a cassette accommodating vessel port which holds a cassette accommodating vessel. The vessel is filled with clean air or an inert gas, and is airtightly closed. A cassette receiving mechanism is disposed below the port and lowers only the cassette of the vessel so as to receive the cassette. Thus, when the cassette is input and output to and from the outside of the treatment apparatus, the workpiece contained within the cassette is not exposed to the atmosphere in a working region. Consequently, it is not necessary to improve the cleanliness level of the atmosphere in the working region.Type: GrantFiled: June 24, 1996Date of Patent: November 3, 1998Assignee: Tokyo Electron Kabushiki KaishaInventors: Hiroyuki Iwai, Tamotsu Tanifuji, Takanobu Asano, Ryoichi Okura

Patent number: 5772392Abstract: An object picking system includes a plurality of object storage and discharge devices. Each object storage and discharge device includes an object storage section housing a stack of objects and an object discharge mechanism for discharging the bottommost object of the stack of objects. Each object discharge device is inclined so that part of the weight of the objects rests on the sides of the object storage sections. Each object storage section accommodates a support between a top and bottom of the object storage section to support an upper stack of objects in the object storage section. The support reduces the load on the bottommost object when the stack of objects in the object storage section is large. An auxiliary panel along one side of the object storage section has an adjustable position so that different size objects can be securely held in the object storage section. A horizontal plate is a predetermined height above a bottom surface of the object storage section.Type: GrantFiled: August 20, 1996Date of Patent: June 30, 1998Assignee: Okura Yusoki Kabushiki KaishaInventors: Ryoichi Okura, Yutaka Saeki

Patent number: 5713718Abstract: An object discharge mechanism of an object picking device for discharging a bottommost object from a stack of objects includes a bottom platform on which the bottommost object of the stack of objects rests. The platform has a longitudinal slot running along an object discharge direction. The upper portion of a belt, stretched between two vertically mounted pulleys, runs through the longitudinal slot parallel to the upper surface of the bottom platform. Discharge projections are mounted periodically on an outer surface of the belt. The discharge projections push objects across the bottom platform in the object discharge direction when the belt is rotated. The object discharge mechanism also includes a lifting member for lifting all objects above the bottommost object in the stack of objects. The lifting member reduces the frictional force created by the weight of the stack of objects on the bottommost object during discharge of the bottommost object.Type: GrantFiled: August 19, 1996Date of Patent: February 3, 1998Assignee: Okura Yusoki Kabushiki KaishaInventors: Ryoichi Okura, Yutaka Saeki
