Abstract

PURPOSE:To facilitate installation of fluid pipes and piping work by integrally connecting a multi-piping joint, a speed controller and the like to an actuator in such a manner that they can be turned at a specific angle. CONSTITUTION:Speed controllers 54a-54c are joined to air cylinders 44a-44c, respectively as to turn at specified angle. Double-piping joints 56a-56c are joined to the double-piping joints 56a-56c, respectively. Since the number of pipes which carry air to drive the air cylinders 44a-44c can be reduced significantly, the piping work can be performed easily. In addition, the speed controllers 56a-56c can be turned so that a design modification can be performed freely.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an actuator drive system, and more particularly, the present invention relates to an actuator drive system, in which a pipe joint for multiple pipes, a speed controller, etc. are integrally attached to an actuator operated by fluid pressure, and The present invention relates to an actuator drive system configured such that pipe fittings, speed controllers, etc. can be rotated by a predetermined angle, thereby making it possible to easily arrange a pipe body for fluid to be supplied to the actuator.

BACKGROUND ART Conventionally, systems have been widely used in which a plurality of pipe bodies are connected to a single pressure fluid supply source, and a directional switching valve or the like for driving an actuator is interposed in each pipe body.

In this case, the actuator includes a first port for introducing fluid for driving the actuator in a predetermined direction, and a second port for introducing fluid for driving the actuator in the opposite direction. It is normal that it is formed. Therefore, the tube for the first boat and the tube for the second boat are respectively connected to the actuator. A specific example is shown in FIG.

That is, the system 2 for driving an actuator according to the prior art includes a manifold 4 connected to a pressure fluid supply source (not shown) via a pipe body, and a plurality of actuators driven by the system 2, such as an air The manifold 4 includes solenoid valves 8a-, 8b, 8c corresponding to the number of air cylinders 6a, 6b, and 6c. The solenoid valve 8a is installed on one side of the manifold 4.
Ports 10a and 1Ob are defined which communicate with the
Ports 12a, 12b communicating with the electromagnetic valve 8b and ports 14a, 14b communicating with the electromagnetic valve 8c are formed on one side of the manifold 4.

On the other hand, any one of the air cylinders 6a to 6c
One side of each air cylinder 6a has a speed controller 1 that engages with one port of the air cylinder 6a.
6a and the speed controller 1 that engages with the other port.
6b is attached. The speed controller 15a
, 16b has a pipe joint 18a integrally formed therewith.
, 18b are provided, respectively. Similarly, speed controllers 2Q are also applied to the other air cylinders 6b and 6c, respectively.
a, 20b and 22a, 22b are arranged, and these speed controllers 20a, 20b and 22a, 22b
are provided with pipe joints 24a, 24b and 26a, 26b, respectively. Each port 10a, 10b, 12a, 12b, 14a, 14 formed in the manifold 4
b, and pipe joints 18a, 18b% 24a% 24b, 26a, 26 communicating with the air cylinders 6as6b, 6c.
b are tube bodies 30a and 30b, respectively.

32a, 32b, 34a, and 34b.

In such a configuration, air supplied from a pressure fluid supply source (not shown) connected to the manifold 4 is selected through predetermined flow paths by solenoid valves 8a, 8b, and 8c, and is sent to air cylinders 6a, 6b, and 6c, respectively. Supplied.

In this case, the amount of air supplied is controlled by the speed controller 1.
6a, 16b, 20a, 20b, 22a, 22b can be set in advance to bring the operating speed of the air cylinders 6a, 6b, 6c to a desired value.

However, in the system 2 configured as described above, for example, the speed controllers 16a and 16b and the pipe joint 18 are connected to the two ports of the air cylinder 6a.
A and 18b are provided separately, and accordingly, pipe bodies 30a and 30b for supplying fluid from the manifold 4 to the air cylinder 6a are also provided separately. Therefore, when a plurality of air cylinders 6a s 6b s 6c are arranged as in the system 2, the number of pipe bodies for supplying air to the air cylinders 6a, 6b, 6c increases significantly, and the occupied area will expand all at once.

In other words, the configuration of the system itself becomes more complex,
The work of arranging the tube becomes extremely complicated, and it becomes difficult to effectively utilize the narrow space. Furthermore, when the number of piping steps increases in proportion to the number of pipe bodies as described above, the risk of erroneous connections between ports, so-called erroneous piping, increases. Furthermore, in the system 2, depending on design changes, for example, the port 10a and the pipe fitting 18 may be
b, port 10b, and pipe joint 18a, respectively, the pipe bodies 30a and 30b must be cross-piped, and in some cases, the pipe bodies 3Qa and 30b may be connected to other pipe bodies 3Qa and 30b. The pipe body may have to be replaced and connected, and re-piping work may be required. This manifests itself as an extremely troublesome inconvenience.

The present invention has been made in order to overcome the above-mentioned disadvantages, and provides an actuator operated by fluid pressure, in which a pipe joint for multiple pipes, a speed controller, etc. are integrally disposed in the actuator, and a pipe joint for multiple pipes, a speed controller, etc. The pipe joint and the speed controller are configured to be rotatable by a predetermined angle to ensure ease of installation of fluid pipes that supply fluid to a plurality of ports of the actuator, and also to allow the number of pipes that supply fluid to the actuator to be changed. To provide an actuator drive system that greatly reduces piping work, facilitates piping work, avoids incorrect piping, and can easily accommodate design changes. With the goal.

In order to achieve the above object, the present invention provides a system for driving a plurality of actuators actuated by fluid pressure, wherein at least each of the actuators has a plurality of pipes for connecting multiple pipes forming a plurality of passages. The pipe joint for multiple pipes is configured to be rotatable by a predetermined amount with respect to the actuator, so that the connection between the port of the actuator and the pipe body can be freely selected.

The air introduced into the small chamber 99a from the hole 86a reduces the diameter of the packing member 100a due to its pressure, and the chamber 89a divided by the packing member 100a becomes the small chamber 99a.
It passes through to the small chamber 97a side and is introduced into the recess 82a through the hole 83a.

As shown in FIG. 3, the recess 82a is a passage 76a defined in the cylinder body 64 of the air cylinder 44a.
