Patent number: 5774355Abstract: In a programmable controller system, a sequence program, an operation sequence control program module and a plurality of I/O control program modules including interlock control are independently provided. In the interlock control of the start condition and the operation end condition of an actuator, an interlock condition set program is separated from the operation sequence control program, and the interlock condition is described in a table, thereby easily setting the interlock condition in the form of a table. As described above, when the operation sequence control program executed by a programmable controller and the input/output control program including the interlock control are independently provided, the number of steps in programming can be decreased, and reliability and maintenance performance of the program can be improved.Type: GrantFiled: December 9, 1996Date of Patent: June 30, 1998Assignee: Canon Kabushiki KaishaInventors: Yoshihiro Mizuno, Ryohei Inaba, Hideki Yamaguchi

Patent number: 5498122Abstract: This invention discloses a method for supplying a robot for assembling or working on works or component parts, with the works contained in pallets through a supply apparatus. The pallets in stacked state, containing the works, are delivered to an elevator in the supply apparatus, then moved to a work supply position by the elevator, and maintained in this position for effecting the pick-up operation of the works by the robot. When a pallet is emptied, the empty pallet is moved from the work supply position to a discharge position, and the empty pallets are circulated to an empty pallet discharge position.Type: GrantFiled: June 29, 1994Date of Patent: March 12, 1996Assignee: Canon Kabushiki KaishaInventors: Toshihiko Miura, Ryohei Inaba

Patent number: 5143736Abstract: An injection molding apparatus includes a screw housed in a heating cylinder, a rotator for rotating the screw, a linear mover for moving the screw linearly, a motor for driving the rotator, a driver for driving the linear mover, and a base member for supporting the screw, the rotator, the linear mover, the motor and the driver. The screw, the linear mover and the rotator are supported by the base member along a vertical line against the ground. In the injection molding apparatus is a nozzle touch mechanism which includes a support member mounted on the base member, and a member for mounting a die member mounted on the support member to support the die member. The die member is mounted by the member for mounting the die member so that a molding material entrance port of the die member engages an injection port of the heating cylinder.Type: GrantFiled: June 1, 1990Date of Patent: September 1, 1992Assignee: Canon Kabushiki KaishaInventors: Masaaki Kumamura, Ryohei Inaba, Shojiro Danmoto, Mitsuo Arai

Patent number: 5102587Abstract: An injection molding apparatus includes an electrically driven injection apparatus in which a screw accommodated in a heating cylinder is driven by a motor. The injection apparatus includes a pressure detection device for detecting an injection pressure of the screw and a device for detecting a stroke of the screw. Speed control is first conducted until the preset packing rate which represents that a dwell process is almost started is obtained, and the remaining injection process and the dwell process are conducted using an output of the pressure detection device. If a volume of resin in the cylinder which is required to fill the cavity is obtained beforehand, a packing rate of the molding material in the cavity is obtained by detecting the screw stroke. A packing rate which represents that the dwell process is nearly started is preset, and speed control of the screw is conducted and the resin is thereby packed at a fixed injection rate until when that preset packing rate is obtained.Type: GrantFiled: July 24, 1990Date of Patent: April 7, 1992Assignee: Canon Kabushiki KaishaInventors: Masaaki Kumamura, Ryohei Inaba, Yozo Tobo, Hirofumi Sugawara, Tadanobu Miyazaki
