Abstract

PURPOSE:To simpify design and installation of a system and reduce the size of a controller by integrally installing a valve body, position detector, and a control module onto a cylinder body. CONSTITUTION:A valve body 14 for controlling the hydraulic pressure for piston transfer, a position detector 16 for detecting the position of a piston, and a control module 32 which transmits the information detected by the position detector 16 into a controller and controls the valve body 14 on the basis of the control signal transmitted from the controller are installed integrally onto a cylinder body 12. Therefore, the necessity of preparing configuration and installation plans for setting each part into an organic system, etc., piping, wiring, etc. can be obviated. Thus, the design and installation of the system can be simplified, and since the control module 32 can be separated from the controller, the size of the controller can be reduced.

The position of the piston 10 in the cylinder main body 12 is detected based on the position of the screw 1 and screw 22 detected by a and 16b. However, such a conventional cylinder device i''f3L,
- The valve body 14 and the position detector 1G are formed completely separately from the cylinder body 12, and include three J-types, in particular, the position detector 16 and the cylinder head 12.
ffiloo is installed on the equipment side (J), but the device 200 including the valve body 14 is generally installed (A5) at a position quite far away from the installation (I) side, and the cylinder body 12
and the valve body 14 were connected by a hydraulic piping. For this reason, with conventional cylinder devices, it is necessary to create layout drawings and installation diagrams to organically systemize these parts when installing them, and it is also necessary to prepare drawings for the actual installation.

By incorporating it, the entire surface mounting is made smaller. However, the conventional control device 30, as shown in FIG. Therefore, there was a drawback that there was a limit to its miniaturization. In particular, when a plurality of cylinder devices are controlled by one control device 30, the number of these 1-in-1-roll modules 32 corresponding to each cylinder device is required. Is it all good? In order to increase the size to 11 full size, effective countermeasures are needed.
