Problems solved by technology

Therefore, it is impossible to adopt a structure in which only a part of the fluid pressure cylinders is connected with a check valve and a throttle valve.
As a result, it is difficult to construct a cylinder drive device that meets the user's application

Embodiment Construction

[0023] Hereinafter, preferred embodiments of the cylinder drive device and the flow path unit according to the present invention will be described in detail with reference to the drawings.

[0024] [1. Structure of this embodiment]

[0025] like figure 1 As shown, the cylinder driving device 10 according to this embodiment is used to drive a plurality of fluid pressure cylinders 12 . The fluid pressure cylinder 12 is, for example, an air cylinder, and has a cylinder portion 14 and a piston 16 . The piston 16 divides the inside of the cylinder part 14 into a first cylinder chamber 18 and a second cylinder chamber 20 , and can reciprocate and slide inside the cylinder part 14 by the action of fluid pressure. A piston rod 22 is connected to the piston 16 . One end of the piston rod 22 is connected to the piston 16 , and the other end extends from the cylinder 14 to the outside.

[0026] The fluid pressure cylinder 12 performs operations such as positioning of a workpiece (not...

Abstract

In a cylinder drive device (10), a throttle valve (70) and a second check valve (74) are provided between a switch valve (28A) and a first cylinder chamber (18) of a fluid pressure cylinder (12A). The cylinder drive device (10) has a flow channel unit (30) which is interposed between a manifold (26) and the switch valve (28A), which allows communication between the throttle valve (70) and the second check valve (74) and switch valve (28A), and which communicates with a plurality of holes in the manifold (26) to allow a fluid to flow to the switch valve (28A).

Description

technical field [0001] The present invention relates to a cylinder driving device and a flow path unit for the cylinder driving device, the cylinder driving device uses a plurality of switching valves installed in a manifold to supply fluid pressure to first cylinder chambers and second cylinder chambers of a plurality of fluid pressure cylinders The fluid is supplied alternately. Background technique [0002] In the past, for example, Japanese Patent Application Laid-Open No. 2001-311404 discloses a cylinder driving device in which, for one fluid pressure cylinder, a fluid such as air is alternately supplied to a first cylinder chamber and a second cylinder chamber divided by a piston. Drive the fluid pressure cylinder. [0003] In addition, when driving a plurality of fluid pressure cylinders, it is preferable to attach a plurality of switching valves to a manifold formed with a plurality of holes through which fluid flows. In this case, the fluid is supplied from the fl...
