Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fluid supply device that can supply fluid at any position on a guide rail.

[Prior Art] Known air supply devices supply air through ports fixed to piping installed in the factory, so when one person is working on two processes, it is necessary to use tube reels, etc. Must be used and moved. In addition, even if the work line is changed, the position of the port is fixed, so it is necessary to connect it with a tube.Furthermore, when supplying compressed air to a fluid pressure actuator, the fixed port and the fluid pressure actuator must be connected. Must be connected by tube.

Therefore, there is a problem that the air supply tube becomes tangled or becomes a hindrance to the work, reducing work efficiency.

[Problems to be Solved by the Invention] An object to be solved by the present invention is to provide a fluid supply device with a simple configuration and good workability.

[Means for Solving the Problems] In order to solve the above problems, the fluid supply device of the present invention includes a cylindrical guide rail having a longitudinal slit, and a flow passage whose both ends open inside and outside the guide rail. The device is characterized by comprising a port block that is movable along a slit, and a flexible tube that connects a port provided in the guide rail and an inner opening of the flow path within the guide rail.

Furthermore, in order to solve the same problem, it is preferable to separately connect two ports provided in the guide rail and two flow paths provided in the port block using double spiral tubes.

Furthermore, in order to solve the same problem, it is preferable to individually connect a plurality of port blocks and a plurality of ports on both sides of the guide rail using a plurality of flexible tubes.

In addition, in order to reduce the number of types of guide rails,
A connecting fitting portion may be provided at one end or both ends of the guide rail.

[Operations and Effects of the Invention] By moving the port block along the slit in the longitudinal direction of the guide rail, fluid can be supplied to any position on the guide rail.

In this case, the flexible tube inside the guide rail
It does not interfere with work, and since there is no need to seal the slit, the structure is simple and inexpensive.

In addition, the inner openings of the two ports provided on the guide rail and the two flow paths provided on the port block,
Since they were connected individually with double spiral tubes,
Two types of fluids can be supplied by one fluid supply device, and the two tubes do not become entangled within the guide rail.

Furthermore, since the inner openings of the plurality of port blocks and the plurality of ports on both sides of the guide rail are individually connected by the plurality of flexible tubes, it is possible to supply a plurality of fluids with one fluid supply device, and Desired fluid devices such as fluid pressure actuators and valves can be directly attached to these port blocks regardless of the distance between the ports of the fluid devices.

Further, since a connecting fitting portion is provided at one end or both ends of the guide rail, it is possible to adapt to long lines and curves by connecting, so that the number of parts can be reduced.

[Embodiment] Figures 1 to 6 show a first embodiment of the present invention, and this fluid supply device includes a cylindrical guide rail 1 and a slit 2 opened in the longitudinal direction of the guide rail 1. A movable port block 3, an end block 4 and an end plate 5 that close both ends of the guide rail 1 in the longitudinal direction, and a flow path 6 formed in the port block 3 and the end block 4 with both ends opening inside and outside the guide rail 1. , 7, and a spiral tube 8 connecting these channels 6, 7 within the guide rail 1.

The port block 3 includes an upper part 3a that projects from the slit 2 to the outside of the guide rail 1, a lower part 3b that moves within the guide rail 1, and a narrow connection part that passes through the slit 2. A supply port 11 is formed in the opening, and a so-called one-touch fitting 12, which locks the tube 8 upon insertion, is attached to the inner opening. In addition, the lower part 3
b is provided with concave grooves 13, 13 on both sides, and the concave grooves 13,
13 is loosely fitted into protrusions 14, 14 formed in the longitudinal direction of the inner circumferential surface of the guide rail 1, thereby preventing the port block 3 from rotating.

The spiral tube 8 is made of an elastic material such as a soft synthetic resin, and is configured to be able to expand and contract in the longitudinal direction of the rail 1 by a spiral, and both ends of the spiral tube 8 are attached to the inner openings of the flow channels 6 and 7. Fitting 1

Further, the outer opening of the flow path 7 may be a port 16 into which a pipe is screwed (see FIG. 5) instead of the one-touch fitting 12 into which the fluid supply tube 15 is inserted. , 16 can also be opened in a direction perpendicular to the plane containing the slit 2.

Further, a mounting screw hole 17 may be provided on the opposite side of the guide rail 1 from the slit 2 (see FIG. 6).

In the first embodiment, by moving the port block 3 in the longitudinal direction of the guide rail 1 through the slit 2, pressure fluid can be supplied at any position in the longitudinal direction. Further, since the tube is provided inside the guide rail 1, the tube does not interfere with the work, and there is no need to seal the slit 2, so the structure is simple and inexpensive.

Further, since the rotation of the port block 3 is restricted by the protrusions 14, 14 and the grooves 13, 13, movement is smooth.

Further, since the ports 11 and 16 can be oriented in a desired direction according to the fluid supply direction, connection to a fluid pressure source or fluid pressure equipment is easy. Furthermore, the guide rail 1 can be fixed to a desired object in a factory using the screw holes 17.
