摘要： The rodless cylinder includes at least a cylinder tube and a piston, but it has no piston rod that is indispensable in the conventional cylinders. The article carrier is connected via the piston yoke to the piston and movable with parts and jigs placed thereon as the piston moves along the cylinder. At least one rod is fixed relative to the cylinder tube to extend in parallel with the direction in which the piston and hence the carrier moves. The sensor is provided to be movable along the rod as the piston moves. The sensor has a moving member movable along the rod as the piston moves within the cylinder tube, for detecting a current position of the piston in accordance with relative positional relation between the moving member and the rod. With such arrangements, the rodless cylinder as a whole has a higher rigidity against heavy load, and also the piston can be accurately positioned to stop at a desired position in its stroke.

摘要翻译： 无杆气缸至少包括气缸管和活塞，但是在传统气缸中不具有活塞杆。 当活塞沿着气缸移动时，物品载体通过活塞轭连接到活塞并且可随着部件和夹具放置在其上而移动。 至少一个杆相对于缸筒固定成平行于活塞和因此的载体移动的方向延伸。 当活塞移动时，传感器被设置成可沿杆移动。 当活塞在缸筒内移动时，传感器具有可沿杆移动的移动构件，用于根据移动构件和杆之间的相对位置关系检测活塞的当前位置。 通过这样的布置，无杆气缸整体上具有较高的抵抗重负荷的刚性，并且活塞也可以被准确地定位成在行程中停止在期望的位置。
