摘要： PURPOSE: To strengthen a locking force between both units and to make it difficult to separate by incorporating in a combining device a cam which is turned around a turning shaft, an engaging pin with which the cam engages and a cylinder for driving the cam. CONSTITUTION: When the unit 2 is brought into contact with the unit 3, a control valve is operated, air is fed to respective air cylinders 17 in the direction opposite until then, and a piston rod 24 is synchronously protruded. Whereupon, three cams 15 are turned around a supporting pin 16 as the center, and an arc-like engaging part 15a is brought into contact with an engaging pin 46 of a second unit 3. Since a distance between the engaging part 15a of the cam 15 and the supporting pin 16 is minimum at a place near the engaging pin 46, and it is gradually increased as the engaging part leaves the engaging pin 46, a force for pressurizing the engaging pin 46 is increased as a turning angle is increased. Thus, the combination between both units 2, 3 is locked and held.

摘要： PURPOSE: To enlarge a combining force and to prevent defective operation by turning a cam, bring its engaging part into contact with an engaging pin and pressurizing them to combine both units. CONSTITUTION: When the cam 15 is turned toward the engaging pin 46 with a cylinder 17 in a state that contacting surfaces of both units 2, 3 are brought into contact, the engaging part 15a of the cam 15 is brought into contact with the engaging pin 46 in a part wherein a distance from a turning shaft is equal to a distance between the engaging pin 46 and the turning shaft. Further, when the cam 15 is turned, since the engaging pin 46 is pressurized with the engaging part 15a in a part wherein the distance from the turning shaft is larger than a distance between the engaging pin 46 and the turning shaft in a combining state, both units 2, 3 are combined and locked.

摘要： PURPOSE: To provide an overload detection device being good at durability, flexibility, repeatability, and maintainability and responding quickly. CONSTITUTION: This overload detection device 100 mounted between the end of a robot arm and tool includes a pneumatic chamber subassembly 1 and a stemmed plate 2 pneumatically secured in a unique 'engaging registration' relationship under normal loading conditions, in which case the elevated sealing surface 56 of an annular metal bearing member 16 fixed to the pneumatic chamber subassembly 1 sets an airtight sealed condition. In the event of an excessive load, the engaging registration relationship is upset to allow air to immediately escape and a normally rigid direct coupling set by the overload detection device 100 to become compliant. At the same time, a pressure sensor 3 senses a reduction in pressure and a piston not shown in the figure actuates a switch in the pressure sensor 3. An electrical output signal thereof halts the robot arm.

摘要： PURPOSE: To connect both units to each other always in a suitable contact state so as to prevent fallout of the tool side unit by providing one of both units with a proximity switch operated when mating surfaces of both units approach, and recognizing the contact state of the mating surfaces of both units according to the operation of the switch. CONSTITUTION: When mating surfaces 2a, 3a of both units 2, 3 of an automatic tool replacing device approach, a change in electrostatic capacity or a magnetic field is sensed so that a proximity switch 12 is operated. Accordingly, an electric signal from the proximity switch 12 is transmitted to an operating means such as a robot or the like, and in response to the signal, two engagement levers 10 provided in the first unit 2 of the automatic tool replacing device are pivoted upward to be open, and engaged with two engagement pins 11 provided in the second unit 3. Thus, both units 2, 3 are connected to each other and locked. Accordingly, the engagement levers 10 are not quite pivoted in the condition where the mating surfaces 2a, 3a of both units 2, 3 are not suitably in contact with each other.

摘要： PURPOSE: To eliminate sliding so as to reduce wear by providing first, second and third sealing members respectively between a body and a valve element, between the valve element and a valve guard, and between the body and a male coupling in the cylindrical body of a female coupling, and making the third sealing member replaceable. CONSTITUTION: A cylindrical coupler body 11 has a valve opened/closed by insertion/detachment of a nipple 30. The valve is composed of a valve guard 12, a valve element 16 and a compression spring 22. The valve guard 12 comprises a seal part 12a and a bar-like support part 12b and has a second sealing member 13. A first sealing member 21 is fitted to the outer periphery of the valve element 16. A third sealing member 26 is detachably fitted into the vicinity of an insert port 27 of the inner surface of the coupler body 11. When a nipple body 31 is inserted, an abutting surface 43 moves the valve element 16, and s seal face 20 is separated from the second sealing member 13 to open a passage of a coupler 10. There is no sliding of each sealing member, so that there is hardly wear.
