Patent number: 8973452Abstract: In a body of an electric actuator, dust collecting pipes are disposed as a pair along an axial direction of a hole portion of the body. The dust collecting pipes are connected respectively to negative pressure supply ports provided in an end block, and include plural first through fifth suction holes separated mutually along an axial direction of the dust collecting pipes. Distances between the first through fifth suction holes are formed so as to become smaller stepwise from one end side of the dust collection pipes, on the side of the negative pressure supply ports, to the other end side thereof.Type: GrantFiled: November 29, 2012Date of Patent: March 10, 2015Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shoichi Makado, Hiroyuki Shiomi

Patent number: 8708131Abstract: A stopper cylinder is equipped with a body having a drive unit, a piston mechanism being displaceable along an axial direction in the interior of a tube connected to the body, and a stopper lever connected to the piston mechanism for stopping conveyance of a workpiece. Displacement of the piston mechanism is restricted by an electromagnetic lock mechanism, which is disposed on the body and is excited by supply of electric power. After approaching the workpiece, by releasing a locked state of the electromagnetic lock mechanism, the piston mechanism is displaced to a position facing the workpiece by an elastic force of a spring.Type: GrantFiled: December 19, 2012Date of Patent: April 29, 2014Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shoichi Makado, Masaki Miyahara

Patent number: 8622365Abstract: A pinch valve includes a spring disposed between a movable iron core of a solenoid and an end cover thereof, and which urges the movable iron core toward the side of a tube provided in a body. An elastic force of the spring is set to be smaller than a reactive force of the tube that is applied to a valve plug. In a non-excited state of the solenoid, the valve plug is pressed toward the solenoid by the reactive force of the tube, so as to enable a fluid to flow through a flow passage of the tube. Conversely, in an excited state of the solenoid, since an attractive force of the movable iron core toward the tube is added to the elastic force of the spring, the valve plug is pressed in opposition to the reactive force of the tube for thereby blocking the flow passage.Type: GrantFiled: May 16, 2012Date of Patent: January 7, 2014Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shoichi Makado, Yasuhiro Ushijima

Publication number: 20130150193Abstract: A tooth-skipping prevention mechanism includes a block, which is inserted displaceably into a first end block in an electric actuator. A cavity having a semicircular shape in cross section is formed in one end of the block facing toward an outer circumferential side of a drive pulley and recessed toward another end side of the block. In addition, the cavity is arranged at a predetermined distance with respect to an outer circumferential surface of a timing belt that is enmeshed with the drive pulley. When the timing belt is moved in a radial outward direction so as to separate away from the drive pulley, movement of the timing belt is restricted, whereby the enmeshed condition of the timing belt and the drive pulley is maintained.Type: ApplicationFiled: February 28, 2012Publication date: June 13, 2013Applicant: SMC Kabushiki KaishaInventors: Yoshihiro FUKANO, Shoichi Makado, Masaki Imamura

Patent number: 8303007Abstract: A drive mechanism and a gripper mechanism equipped with the drive mechanism are provided. An electrical gripper includes a drive mechanism equipped with a motor, a feed screw that transmits a rotary drive force from the motor to a feed nut capable of displacement in an axial direction, and a gripper section that grips a workpiece by coupling to the feed nut and being displaced thereby. The drive mechanism further is constituted by a self-locking mechanism, which prevents the feed nut from being retracted as a result of a reactive force received in the event that the feed nut is advanced and the workpiece is gripped by the gripper section.Type: GrantFiled: October 30, 2008Date of Patent: November 6, 2012Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shoichi Makado

Patent number: 8030813Abstract: A servo motor is equipped with a rotary shaft, a rotor rotated integrally with the rotary shaft, a stator that is separated a predetermined distance from and disposed in confronting relation to the rotor, and an angle detecting device that detects an angle of rotation of the rotary shaft. On a counter-load side end, which is opposite to a load side end of the rotary shaft, an operating member is provided, which enables the rotary shaft to be rotated manually from an exterior location.Type: GrantFiled: October 22, 2008Date of Patent: October 4, 2011Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shoichi Makado

Patent number: 7753167Abstract: A silencer includes a cylindrical member held between a body connected to an exhaust side of a fluid pressure device and a disk-shaped retaining member. A net-shaped sound absorber is disposed around an outer circumference of the cylindrical member. A pressure fluid flows from the body into the interior of the cylindrical member and is discharged toward the sound absorber through a plurality of first through fifth exhaust holes formed in the cylindrical member. Accordingly, dust in the pressure fluid is removed by the sound absorber, which is formed of a plurality of stacked filters, and further, the pressure fluid is discharged to the outside after exhaust noises have been absorbed by the sound absorber.Type: GrantFiled: January 12, 2006Date of Patent: July 13, 2010Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shoichi Makado

Patent number: 7712484Abstract: A piston, which is displaceable by pilot air, is provided in a main body. A valve plug, which is composed of a resin material, is connected to an end of a shaft connected to the piston. The valve plug is seated on a valve seat section of a sub-body connected to the main body, and thus the flow of the paint to a flow passage is cut off. A seating section of the valve plug, which is to be seated on the valve seat section, is formed to be substantially spherical. Further, the surface of the valve seat section is recessed and substantially spherical corresponding to the seating section.Type: GrantFiled: July 8, 2005Date of Patent: May 11, 2010Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shoichi Makado
