Abstract: A chuck apparatus includes a pair of grip members driven by a piston via a pair of levers, and the levers are rotatably supported by a body via lever shafts. A lever shaft protrudes from the attachment surface of the body to the transport device, and positioning with respect to the transport device is performed by using the protruding portion.

Abstract: A piezoelectric valve includes a housing provided with an inflow hole and an outflow hole for air, and a valve element disposed in the housing and configured to open and close the inflow hole. The valve element is configured by a piezoelectric unit including a plate-shaped piezoelectric element and a diaphragm on which the piezoelectric element is stacked. The inflow hole does not overlap the piezoelectric element but overlaps only the diaphragm when viewed from a stacking direction of the piezoelectric element in the piezoelectric unit.

Abstract: A piezoelectric valve is a piezoelectric valve driven by a DC component, and includes a plurality of piezoelectric elements electrically connected in parallel via electrodes made of a metal-plated film; a conductive diaphragm joined to the plurality of piezoelectric elements via the electrodes; and a resistor electrically connected to the plurality of piezoelectric elements, and an electric resistance value of the resistor is less than an insulation resistance value of each of the piezoelectric elements.

Abstract: A plurality of vacuum suction cylinders are connected to each other by using tie rods inserted into insertion holes penetrating side walls of a cylinder tube of each vacuum suction cylinder, insertion holes provided in a first flow path block, and insertion holes provided in a second flow path block, and sandwiching between the first flow path block and the second flow path block.

Abstract: A hydraulic cylinder includes a cylinder housing having an accommodation chamber, and a cylinder unit. The cylinder housing has a first securing portion. The cylinder unit has a piston, a piston rod with which the piston is provided, a sleeve for accommodating the piston and a second securing portion. The cylinder unit is accommodated in the accommodation chamber. The cylinder unit can be detachably attached to the cylinder housing due to engagement of the first securing portion with the second securing portion.

Abstract: A magnet gripper includes a piston assembly that includes a permanent magnet. An indicator sheet including a print medium in which a photonic crystal is used is attached to a side surface of a cylinder tube.

Abstract: A fitting nut made of a resin material includes: a hollow, large-diameter tube portion having a female thread formed on its inner peripheral wall; and a small-diameter tube portion that is continuous to the large-diameter tube portion and having a hollow cylindrical shape with a smaller diameter than the large-diameter tube portion. The small-diameter tube portion includes, in the outer peripheral wall thereof, a plurality of engagement grooves that are depressed inwardly in the diameter direction of the small-diameter tube portion and extend along the longitudinal direction that is orthogonal to the diameter direction.

Abstract: A position detecting switch detects the position of a movable body that is capable of moving in a predetermined direction, based on a magnet attached to the movable body. The position detecting switch is equipped with a magnetic sensor that detects the magnetism of the magnet, and outputs a detected value in accordance with the magnetism, a determination unit that determines whether or not the detected value lies within a predetermined range, and a setting unit that sets the predetermined range centrally around the detected value at a specified position which is a position of the movable body specified by an operator.

Abstract: A chuck unit includes a first pressure chamber and a second pressure chamber disposed on both sides of a piston for driving fingers. A valve unit includes a first output air flow path connected to one of the first and second pressure chambers, a second output air flow path connected to the other thereof, a first solenoid valve connected to the first output air flow path, and a second solenoid valve connected to the second output air flow path. The first solenoid valve connects the first output air flow path to an air supply source when energized and opens the first output air flow path to atmosphere when de-energized, and the second solenoid valve opens the second output air flow path to atmosphere when energized and connects the second output air flow path to the air supply source when de-energized.

The small-diameter tube portion includes, in the outer peripheral wall thereof, a plurality of engagement grooves that are depressed inwardly in the diameter direction of the small-diameter tube portion and extend along the longitudinal direction that is orthogonal to the diameter direction.

Abstract: [Object] To make it possible to detect, with a single pressure sensor, a malfunction of two solenoid valves for switching flow paths and to quickly and reliably exhaust residual pressure in an air device through a solenoid valve. [Solution] A residual pressure exhaust air circuit 1 includes: a main flow path 9 through which air from an air source 2 is supplied to an air cylinder 100; an exhaust flow path 10 through which air in the air cylinder 100 is exhausted; a first sensor 8 for detecting a malfunction of solenoid valves 12, 13; a detection flow path 11 through which air from the air source 2 is supplied to the first sensor 8; and the two solenoid valves 12, 13 that switch communication states among the main flow path 9, the exhaust flow path 10, and the detection flow path 11. The two solenoid valves 12, 13 are formed of two-position valves having first positions 12a, 13a at the time of OFF and second positions 12b, 13b at the time of ON and are synchronously ON/OFF controlled.

Abstract: A remote wireless device transmits and receives signals to and from a base wireless device in a transmission/reception period, and includes a transmission/reception processing unit that performs a transmission process of a signal in each of a plurality of continuous transmission/reception periods until transmission to the base wireless device is made successfully. A counting unit counts a number of times the transmission processes is performed. A transmission selection unit selects whether to perform the transmission process or stand by in a next transmission/reception period in accordance with a predetermined rule in a case that a count value by the counting unit is equal to or greater than a predetermined number. A transmission prohibition unit prohibits the transmission process by the transmission/reception processing unit in a case that standby is selected by the transmission selection unit.

Abstract: A vacuum pad includes a support member that includes a vacuum passage and a bellows that is attached to the support member, and the cover body includes a cylindrical body portion, an attaching portion projecting from one end of the body portion, and a flange portion projecting radially outward from another end of the body portion. The cover body covers the outside of the bellows when the bellows contracts and holds a workpiece by suction.
