[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pneumatic device, and more particularly, to a structure for fixing a manifold constituted by a plurality of flow path switching valves.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, pneumatic devices have been used in various industries because they can be labor-saving and automated at low cost. In addition, air pressure has recently been used in semiconductor production lines to keep the environment clean. In addition, in order to save piping and reduce the size, a flow passage switching valve of multiple stations is integrated and used as a manifold.
The manifold is connected to a pneumatic device or the like to control its operation. Since the shorter the connection line between the manifold and the pneumatic actuator can be controlled more accurately, the manifold is installed near the pneumatic actuator. Therefore, it is required to accumulate and fix many manifolds in a limited installation space.
[0003]
Therefore, a conventional manifold fixing structure is shown in FIGS. FIG. 6 is a perspective view of the manifold, and FIG. 7 is a side view of the same. The manifold fixing structure shown in FIGS. 6 and 7 has a structure in which bolts are passed through mounting holes 44 in the height direction provided at four corners of the manifold base 43 and are fixed to the mounting surface 42. That is, as shown in FIG. 7, the manifold 40 is mounted on the mounting surface 42 in the same direction as the mounting direction of the flow path switching valves 41a and 41b.
[0004]
When the manifolds 40 are integrated and fixed in parallel, a manifold base provided with an output port cannot be used. This is because, when the output port is provided on the manifold base, the output pipe is in the direction of integration of the manifold. Therefore, since the output pipe is routed upward, in such a mounting structure, as shown in FIG. 7, the manifold is configured using a switching valve that can connect the output pipe to the flow path switching valves 41a and 41b themselves. are doing.
[0005]
As shown in FIG. 6, the manifold 40 includes a single solenoid type solenoid valve 41a having a solenoid disposed on one side of a main valve body, and a double solenoid type solenoid valve 41b having solenoids disposed on both sides of the main valve body. It is configured to be mounted on the base 43. At four corners of the manifold base 43, mounting holes 44 for fixing are formed. Then, a bolt is passed through the mounting hole 44, and the manifold 40 is fixed to the manifold fixing surface 42 with the bolt.
[0006]
[Problems to be solved by the invention]
However, the conventional manifold fixing structure has the following problems. That is, since the mounting holes 44 in the height direction provided at the four corners of the manifold base 43 are used to fix the manifold 40 to the manifold fixing surface 42 with bolts, the manifold 40 is connected to the manifold fixing surface mounting surface 42 by the flow path switching valve 41a. , 41b can be fixed only in the same direction as the mounting direction. Therefore, there is no flexibility in the installation posture of the manifold 40. Therefore, there is a problem that the manifold 40 cannot be fixed in a limited installation space, and the installation space width L increases.
[0007]
Therefore, the present invention has been made to solve the above problems, and has an object to provide a manifold fixing structure that can increase the degree of freedom of an installation posture of a manifold and can be fixed in a limited installation space. Aim.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, according to the first aspect, a substantially rectangular parallelepiped in which a common air supply channel and an exhaust channel are formed, and a mounting hole is orthogonal to the air supply channel and the exhaust channel. A manifold base formed in the direction in which the air flows, and one or more flow path switching valves that are attached to the manifold base in parallel adjacent to each other and communicate with the air supply flow path and the exhaust flow path, respectively. In a manifold fixing structure for fixing a manifold to a manifold fixing surface, the fluid control valve includes at least one of a single solenoid type and a double solenoid type having different overall lengths, has a substantially L-shape, and one surface is the manifold. The base is mounted on the mounting surface of the flow path switching valve using the mounting hole so that another surface is located outside the fluid switching valve, Be those utilizing surface to secure the manifold to the manifold fixing surface, the surface attached to the mounting surface of the manifold base, in a direction orthogonal to the inlet channel and exhaust channel, the single A first position for adjusting the mounting height of the manifold in accordance with the solenoid type fluid control valve and a second position for adjusting the mounting height of the manifold in accordance with the double solenoid type fluid control valve are long. It is characterized by having a manifold fixing bracket having an elongated hole that opens .
[0009]
According to the fixing structure of the manifold having an upper Symbol configuration, since it has been attached to both ends of the mounting surface of the manifold base of the flow path switching valve, the manifold fixing bracket L-shaped manifold flow path switching valve Since the manifold can be fixed in a direction perpendicular to the direction in which it is mounted on the base, the installation space in the direction perpendicular to the piping direction can be reduced, and the space can be saved.
Further, since the manifold fixing bracket has a long hole, the mounting position of the manifold fixing bracket with respect to the manifold base can be optimally determined in accordance with the size of the flow path switching valve mounted on the manifold base. . Therefore, the installation space can be further optimized.
[0010]
Here, the fixing bracket for the manifold other metals may also be molded in engineering plastics or the like.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a manifold fixing structure according to the present invention will be described in detail with reference to the drawings, taking specific embodiments.
FIG. 1 shows a manifold fixing structure according to a first embodiment of the present invention. FIG. 1 is a perspective view showing a fixing structure of the manifold. In FIG. 1, the manifold base 2 has a rectangular parallelepiped shape, and an air supply passage 6 and exhaust passages 7 and 8 are formed in the longitudinal direction so as to pass through the inside of the manifold base 2. Further, the output flow path 9 communicating with the output ports of the switching valves 1a and 1b in a direction perpendicular to the longitudinal direction does not intersect with the air supply flow path 6 and the exhaust flow paths 7 and 8, and the end face of the manifold base 2 Is formed.
[0012]
Then, a one-touch joint is attached to the opening of the output flow passage 9 and connected to a pneumatic device or the like via a connection tube. The one-touch type joint is an easily attachable / detachable joint in which the connection tube is locked when the connection tube is inserted, the connection tube can be unlocked by pressing the release ring, and the connection tube can be removed.
[0013]
Also, L-shaped manifold fixing brackets 3 are attached to both longitudinal ends of the manifold base 2. The manifold fixing bracket 3 has slots 4 and 5 formed in a portion fixed to the manifold base 2 and a portion fixed to the manifold fixing surface. The mounting height of the manifold 10 can be adjusted by the elongated holes 4, and the mounting position of the manifold 10 can be adjusted by the elongated holes 5. For example, as shown in FIG. 2, in the case of a manifold composed of only a single solenoid type solenoid valve 1a, if the manifold fixing bracket 3 is adjusted to the position shown by the dotted line in FIG. 2 and attached to the manifold base, The manifold can be fixed to the manifold fixing surface in the optimal installation space. In addition, for a manifold including a double solenoid type solenoid valve 1b, the manifold fixing bracket 3 is adjusted to a position shown by a solid line in FIG. 2 and attached to the manifold base, and the manifold is fixed to the manifold fixing surface. good. That is, the manifold can be installed in an optimum space in accordance with the size of the flow path switching valve constituting the manifold.
[0014]
However, in FIG. 2, when the manifold fixing surface side of the manifold fixing bracket 3 is attached to the solenoid side of the single solenoid type, the projection size of the solenoid is the same for both the single type and the double type. There is no merit of adjustment. However, in such a case, when the manifold is fixed, the output pipe is directed upward, and when viewed from the manifold including the pipe, the space saving in the height direction has little significance. Therefore, even if there is no merit of height adjustment, there is almost no problem in actual use.
[0015]
The manifold fixing bracket 3 is attached to the manifold base 2 with bolts 13 by using an attachment hole provided in the manifold base 2. Therefore, the manifold 2 can be fixed in the same direction as the mounting direction of the fluid switching valves 1a and 1b as in the conventional example. At this time, if the manifold fixing bracket 3 is in the way, it can be removed.
[0016]
A method of fixing the manifold will be described with reference to FIG. First, with the one-touch type joint 11 attached to the manifold 10 facing upward, the fitting 3 for the manifold is temporarily fixed to both ends of the manifold base 2 with bolts 13 in the direction in which the L-shape stands. This is because the mounting height is adjusted after the manifold 10 is fixed. Next, the manifold 10 is fixed to the manifold fixing surface 12 with the fixing bolts using the elongated holes 5 of the metal fittings 3 for manifold fixing. Finally, depending on the type of the flow path switching valve mounted on the manifold base, the mounting position of the manifold fixing bracket 3 with respect to the manifold base is optimized by using the elongated hole 4 formed in the manifold fixing bracket 3. And fixed with bolts 13. In FIG. 3, since a double solenoid type solenoid valve 1b is mounted as a flow path switching valve on the manifold base 2, the manifold fixing bracket 3 is fixed at a position indicated by a solid line in FIG.
[0017]
The upward piping manifold fixed as described above can reduce the installation space width L in a direction orthogonal to the piping direction as compared with the conventional example (upward piping), and can be integrated in a space-saving manner. Although only two manifolds are installed in FIG. 3, if the number of installed manifolds increases, the installation space width L can be further reduced. In addition, the installation space in the height direction is smaller in the conventional example, but since the piping tube is attached in the height direction, saving space in the height direction does not make much sense when viewed from the manifold including piping. do not have. In fact, in most cases, there is an empty space in the height direction even when used. Therefore, there is not much problem due to an increase in the installation space in the height direction.
[0018]
Further, as shown in FIG. 3, the present invention can be applied not only to the case where the manifold is installed on the manifold fixing surface parallel to the ground but also to the case where the manifold is installed on the manifold fixing surface perpendicular to the ground. In this case, the pipe direction is parallel to the ground, and the stacking direction is perpendicular to the ground. Therefore, when this embodiment is applied to the case where the manifold is installed on the manifold fixing surface perpendicular to the ground, the installation space in the vertical direction with respect to the ground can be reduced, and a large number of manifolds can be vertically integrated with a small space. Can be fixed.
[0019]
FIG. 4 shows a second embodiment according to the present invention. FIG. 4 shows a case where a manifold on which only a single solenoid type solenoid valve is mounted is fixed with an output pipe directed downward.
Based on FIG. 4, a method of fixing a manifold on which only a single solenoid type solenoid valve is mounted will be described. First, with the instant fitting 11 attached to the manifold base 2 facing downward, the metal fittings for manifold fixing 3 are temporarily fixed to both ends of the manifold base 2 with bolts 13 in the direction in which the L-shape stands. This is for adjusting the mounting height after fixing the manifold 20 to the manifold fixing surface 22. Next, the manifold 20 is fixed to the manifold fixing surface 22 with fixing bolts using the elongated holes 5 of the metal fittings 3 for fixing the manifold. Finally, in accordance with the size of the single solenoid type solenoid valve 1a mounted on the manifold base 2, the mounting position of the manifold fixing bracket 3 with respect to the manifold base 2 is determined by the length of the manifold fixing bracket 3. The hole 4 is used to determine and fix it to be optimum.
[0020]
As described above, according to the manifold fixing structure of the second embodiment, the manifold can be fixed even when the output pipe is directed downward. In the conventional example, in order to lower the output pipe, the manifold cannot be fixed with the output pipe facing downward unless an elbow is provided in the middle of the pipe and the pipe direction is changed. In addition, when an elbow is provided in the middle of the pipe, a problem such as a pressure loss of the output fluid occurs.
Further, since the pipe is located downward, in a manifold in which only a single solenoid type solenoid valve is mounted, the installation space in the height direction can be reduced.
[0021]
In addition, the effect of the height adjustment described above is not limited to a manifold equipped with only a single solenoid type solenoid valve. Even when the valve and the form of the electrical connection are different (difference in the direction of the connector and the specification), the effect of the height adjustment is obtained, and the installation space in the height direction can be reduced.
[0022]
FIG. 5 shows a third embodiment according to the present invention. FIG. 5 shows a case where a manifold on which a double solenoid type solenoid valve is mounted is fixed with an output pipe directed downward.
Based on FIG. 5, a method of fixing a manifold on which a double solenoid type solenoid valve is mounted will be described. First, with the one-touch joint 11 attached to the manifold base 2 facing downward, the metal fittings for manifold fixing 3 are temporarily fixed to both ends of the manifold base 2 with bolts 13 in the direction in which the L-shape stands. This is for adjusting the mounting height after fixing the manifold 30 to the manifold fixing surface 22. Next, the manifold 30 is fixed to the manifold fixing surface 22 with fixing bolts by using the elongated holes 5 of the manifold fixing metal fitting 3. Finally, according to the size of the double solenoid type electromagnetic valve 1 b mounted on the manifold base 2, the mounting position of the manifold fixing bracket 3 with respect to the manifold base 2 is changed to the elongated hole 4 formed in the bracket 3. Utilize and determine and fix to be optimal.
As described above, according to the manifold fixing structure of the third embodiment, similarly to the second embodiment in which the manifold in which only the solenoid valve of the single solenoid type is mounted, the output pipe is directed downward. In such a case, the manifold can be fixed.
[0023]
As described above, according to the manifold fixing structure of the present invention, since the L-shaped manifold fixing metal fittings are attached to both ends of the mounting surface of the manifold base flow path switching valve, the flow path switching valve is provided. Since the manifold can be fixed in a direction orthogonal to the direction in which is mounted on the manifold base, the installation space in the direction orthogonal to the direction of the output pipe can be reduced, and can be integrated and fixed in a space-saving manner.
Further, since the manifold fixing bracket has a long hole, the mounting position of the manifold fixing bracket with respect to the manifold base can be optimally determined in accordance with the size of the flow path switching valve mounted on the manifold base. . Therefore, the installation space can be further optimized.
Further, even when the output pipe is directed downward, the manifold can be fixed without providing an elbow or the like in the middle of the pipe.
[0024]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various applications are possible.
That is, for example, in the present embodiment, a manifold in which a plurality of flow passage switching valves are mounted on a metal-integrated manifold base is used, but the present invention can also be applied to a manifold composed of a resin-based split base.
In addition, if the portion of the L-shaped manifold fixing bracket fixed to the manifold fixing surface is elongated in the longitudinal direction of the manifold and a long hole is formed in the longitudinal direction, the degree of freedom of position adjustment in the longitudinal direction of the manifold can be improved. Spreads.
