[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manifold valve having a plurality of manifold bases on which valves are installed.

[0002]

2. Description of the Related Art A manifold valve in which a plurality of manifold bases on which valves are installed in order to centrally manage a plurality of valves is already known. In this known manifold valve, since one valve corresponds to one fluid pressure device, the size and speed of the fluid pressure device such as a fluid pressure actuator corresponding to the flow rate of the pressure fluid flowing through the valve are determined. Therefore, when a desired amount of pressure fluid is supplied to many types of hydraulic equipment having different sizes and speeds, many types of valves and manifold bases corresponding to each hydraulic equipment must be used. However, using many types of valves and manifold bases not only increases the cost, but also increases the number of parts and makes inventory management cumbersome.

[0003]

A problem to be solved by the present invention is to provide a manifold valve having a wide range of usable hydraulic devices.

[0004]

In order to solve the above-mentioned problems, a manifold valve having a piping cassette according to the present invention is provided with a manifold base having a pressure fluid output port and a valve for outputting a pressure fluid at the output port. A plurality of manifold valves connected in series, wherein a piping cassette attached to the output port has a plurality of insertion portions which have input ports for pressure fluid and are individually inserted into output ports of a plurality of adjacent manifold bases. , A tube mounting portion having an output port, and a communication path for collecting a plurality of input ports and communicating with the output port. Also, in order to facilitate replacement of the piping cassette, the manifold base has a substantially U-shaped mounting groove,
It is characterized in that it is detachably attached to the manifold base by an elastic clip inserted into the attachment groove.
Furthermore, in order to facilitate the molding of the piping cassette, each insertion portion of the piping cassette is provided with a locking flange that locks to the elastic clip, an O-ring that seals the output port, and a flange that prevents the O-ring from falling off. And each of the locking flanges and the flanges,
Each is characterized by having a notch for facilitating die cutting.

[0005]

The pressure fluids output from the plurality of valves can be collected and output from the output port of the piping cassette. Therefore, the supply amount of the pressurized fluid can be increased by the piping cassette, so that the range of usable hydraulic equipment can be expanded. Further, since the piping cassette can be easily attached to and detached from the manifold base by the elastic clip, the change of the tube diameter and the maintenance are easy. Furthermore, the notch part is formed in the locking flange part and the flange part provided in each insertion part of the piping cassette, so that the piping cassette having the flange part and having a plurality of closely arranged insertion parts. Can be integrally formed by a mold having a simple configuration, so that the piping cassette can be made inexpensive.

(In the illustrated example, two insertion ports 16a,... And 16b, which are densely inserted into each of the output ports 4a and 4b.)
And input ports 18a, 18a and 18b, 18b opened in the insertion sections 16a, 16a, 16b, 16b, and output ports 19a, 1 opened in the tube mounting sections 17a, 17b.
9b is communicated with each other by communication paths 20a and 20b. Therefore, compressed air that is a collection of the compressed air output from the two valves 3 and 3 is output from the output ports 19a and 19b of the piping cassette 5. Also,
Each of the insertion portions 16a and 16b has an elastic clip 1
3, an O-ring 23 fitted in the O-ring groove 22, sealing the output ports 4a and 4b, and a flange 24 for preventing the O-ring 23 from dropping off. These locking collars 21,... And collars 24,... Are formed by notches 21a,.
a,... (see FIG. 6), and a so-called one-touch fitting 25 is attached to each tube attachment portion (see FIG. 1). However, the pipe joint of the present invention is not limited to the above-mentioned joint, and a pipe joint having another configuration may be attached, or a thread for directly connecting a pipe may be provided at each output port.

In this embodiment, a desired number of manifold bases 2, on which valves 3 are installed, are connected by connecting surfaces 2b, and end plates 26, 26 are attached to both ends thereof. The connection is made by an appropriate connection means (see FIG. 8).

Can be collected and output from the output ports 19a and 19b provided in the tube mounting portions 17a and 17b of the pipe cassette 5, so that the same Even if the manifold base 2 and the valve 3 are connected in series, the required amount of compressed air can be supplied to a plurality of types of fluid pressure devices (not shown) such as fluid pressure actuators having different sizes and speeds. it can. Therefore, since a single type of manifold base 2 and valve 3 can be used, the overall cost can be reduced, and parts management is easy. When the pipe cassette 5 is pulled out from the valves 3 for maintenance or the like, the O-rings 23,.
・ ・ Since work can be prevented from falling off or damaged, work is simple. Furthermore, the locking flanges 21,...
The notch 21
, 24a,... and the shape of each of these flanges is substantially semicircular, so that each of the insertion portions disposed close to each other has a flange.
