Hereinafter, an embodiment of a connecting device embodying the present invention will be described with reference to FIGS.
First, the pneumatic control device unit using the connection device will be described. As shown in FIG. 1, the pneumatic control device unit 11 constitutes a part of a pneumatic circuit. On the upstream side of the pneumatic control device unit 11, a regulator 12 is provided as a first fluid pressure device that is connected to an air supply source (not shown) and depressurizes the pressure fluid. On the downstream side, a solenoid valve manifold 13 is provided as a second fluid pressure device. The regulator 12 and the solenoid valve manifold 13 are connected to each other via a connection device 14.

  The regulator 12 functions as a fluid pressure device that reduces the pressure of the pressure fluid supplied from the outside to a desired pressure and outputs the pressure fluid to the outside freely. The regulator 12 is formed with a supply port (not shown) to which pressure fluid is supplied from the outside and a discharge port 15 for discharging pressure fluid to the outside. The supply port and the discharge port 15 are communicated by a fluid passage 12 a formed in the regulator 12. A pair of upper and lower first protrusions 17A and second protrusions 17B are formed on the outer edge of the downstream end face 16 of the regulator 12 where the discharge port 15 is open. A female thread is threaded on the inner peripheral surface of the supply port and the discharge port 15.

  On the other hand, the solenoid valve manifold 13 is configured by attaching a plurality of solenoid valves 19 to a manifold block 18. The electromagnetic valve 19 has a function of switching a flow state of the pressure fluid by exciting a current source to displace a valve body (not shown). The manifold block 18 has a plurality of output ports (not shown) on one side surface 18a. A joint 20 is connected to each output port, and a pneumatic actuator such as an air cylinder is connected via a pipe connected to the joint 20. As shown in FIG. 2, the manifold block 18 is formed with one supply port 22 and a pair of screw holes 23 on the upstream end surface 21 extending at right angles to the one side surface 18 a.

  Each of the supply port 22 and the port 23 is internally threaded with an internal thread. The pair of ports 23 are located on both sides of the supply port 22 and below the supply port 22. The port 23 is an exhaust port, and similarly, a pair of exhaust ports is formed on the downstream end surface 16 (see FIG. 1) located on the opposite side of the upstream end surface 21 of the manifold block 18. The port 23 on the upstream end face 21 and the exhaust port on the downstream end face 16 communicate with each other. A supply port (not shown) is formed on the downstream end face 16. The supply port is closed by a plug (not shown). As shown in FIG. 1, the supply port 22 that opens to the upstream end face 21 of the manifold block 18 and the exhaust port that opens to the downstream end face 16 communicate with each other via the fluid passage 13 a of the solenoid valve manifold 13. The port 23 communicates with the exhaust port on the downstream end face 16. The first attachment surface 26 of the block-like body 25 constituting the connection device 14 is in contact with the upstream end surface 21 of the manifold block 18.

  As shown in FIG. 3, an insertion hole 27 is formed in the body 25 at a lower portion thereof and corresponding to the port 23. A connection plug 28 is inserted through the insertion hole 27. In the connection plug 28, a male screw that can be screwed with a female screw of the port 23 is threaded on the outer periphery of the shaft portion 28 a. The connection plug 28 is screwed into the port 23 while being inserted into the insertion hole 27. Therefore, the body 25 is connected to the manifold block 18 by the connection plug 28 in a state where the first mounting surface 26 is in contact with the upstream end surface 21 of the manifold block 18. The first attachment surface 26 is a plane parallel to the upstream end surface 21. As shown in FIG. 4, a bottomed tool hole 29 is formed in the head portion 28 b of each connection plug 28. The tool hole 29 is a hole into which a tool for rotating the connection plug 28 (for example, a hexagon wrench) is inserted. The body 25 is formed with a planar second mounting surface 30 that is in contact with the downstream end surface 16 (see FIG. 1) of the regulator 12 on the side opposite to the first mounting surface 26 (see FIG. 1). Yes.

  A pair of upper and lower first protrusions 31 </ b> A and a second protrusion 31 </ b> B are formed on the outer edge of the second mounting surface 30 of the body 25. The second mounting surface 30 is formed with a pair of grooves 32 extending linearly and parallel to each other on both sides of the first protrusion 31A and the second protrusion 31B.

  As shown in FIG. 5A, the body 25 is connected to the regulator 12 by the first connection member 33, the second connection member 34, and the attachment screw 35. The first protrusion 17A and the second protrusion 17B are formed in a symmetrical shape with the first protrusion 31A and the second protrusion 31B of the body 25, respectively.

  As shown in FIG. 5B, the first connecting member 33 has insertion holes 36 formed on both sides in the length direction. Further, a bottomed tapered hole 37 is provided at a position sandwiched between the insertion holes 36 on one surface of the first connection member 33. As shown in FIG. 5A, the tapered hole 37 is formed so that the opening width in the short side direction of the first connecting member 33 becomes smaller from the opening side of the tapered hole 37 toward the bottom side. As with the first connection member 33, the second connection member 34 is formed with a pair of attachment holes 38 on both sides in the length direction. A female screw is threaded on the peripheral surface of the mounting hole 38. A bottomed tapered hole 39 having the same shape as the tapered hole 37 is provided at a position sandwiched between the mounting holes 38.

  Here, as shown in FIG. 1, the second mounting surface 30 of the body 25 and the downstream end surface 16 of the regulator 12 are in contact with each other, and the first projecting portion 31 </ b> A and the second projecting portion 31 </ b> B of the body 25 are connected to the regulator 12. The first protrusions 17A and the second protrusions 17B coincide with each other. Both first protrusions 17 </ b> A and 31 </ b> A are inserted into the tapered hole 37 of the first connection member 33. The first connection member 33 engages both the first protrusions 17A and 31A. Further, both the second protrusions 17B and 31B are inserted into the tapered hole 37 of the second connection member 34. The second connection member 34 engages both the second protrusions 17B and 31B. As shown in FIG. 5B, a mounting screw 35 is inserted into the insertion hole 36 of the first connection member 33. The attachment screw 35 is inserted into each of the groove 32 and a groove (not shown) formed in the downstream end face 16 of the regulator 12. Further, the attachment screw 35 is screwed into the attachment hole 38 of the second connection member 34.

  On the other hand, as shown in FIG. 1, a communication passage 40 that connects the discharge port 15 of the regulator 12 and the supply port 22 of the solenoid valve manifold 13 is formed in the body 25. The communication passage 40 extends linearly from the discharge port 15 toward the solenoid valve manifold 13, then bends at a right angle, and once extends downward. Further, thereafter, the communication passage 40 is bent at a right angle and extends toward the solenoid valve manifold 13 to reach the supply port 22 of the manifold block 18. Therefore, even if the center of the discharge port 15 of the regulator 12 and the center of the supply port 22 of the solenoid valve manifold 13 do not exist in a straight line, both ports 15 and 22 can be communicated by the communication passage 40. Further, the communication passage 40 extends so as not to cross the connection plug 28 (see FIG. 3).

  The communication passage 40 has an upstream end 41 and a downstream end 42 that are expanded in diameter. The intermediate portion 43 of the communication passage 40 extends with a constant diameter and has a larger diameter than the fluid passage 13a of the solenoid valve manifold 13. Therefore, the flow passage cross-sectional area of the communication passage 40 is larger than the flow passage cross-sectional area of the fluid passage 13 a of the solenoid valve manifold 13. An annular seal member 44 is attached to the downstream end 42 of the communication passage 40. The seal member 44 is sandwiched between the body 25 and the upstream end face 21 of the solenoid valve manifold 13. The seal member 44 has a function of suppressing leakage of compressed air from between the upstream end surface 21 of the manifold block 18 and the first attachment surface 26.

Next, a method for connecting the regulator 12 and the solenoid valve manifold 13 by the connecting device 14 will be described.
First, the first attachment surface 26 of the body 25 is brought into contact with the upstream end surface 21 of the manifold block 18 of the solenoid valve manifold 13, and in this state, the connection plug 28 is inserted into the insertion hole 27 of the body 25. Then, by inserting a tool into the tool hole 29 and rotating the connection plug 28, the connection plug 28 is screwed into the port 23 of the manifold block 18 and the body 25 is connected to the solenoid valve manifold 13. Since a seal member 44 is interposed between the solenoid valve manifold 13 and the body 25, leakage of compressed air from between the upstream end surface 21 of the manifold block 18 and the first mounting surface 26 is suppressed. Is done.

  Further, the downstream end surface 16 of the regulator 12 is brought into contact with the second mounting surface 30 of the body 25, and in this state, the tapered hole 37 of the first connection member 33 is formed in both the body 25 and the regulator 12. The first protrusions 17A and 31A are inserted, and the second protrusions 17B and 31B formed on both the body 25 and the regulator 12 are inserted into the tapered holes 37 of the second connection member 34. In this state, the first connecting member 33 engages the first protrusions 17A and 31A formed on the body 25 and the regulator 12, while the second connecting member 34 is the second protrusion formed on the body 25 and the regulator 12. The parts 17B and 31B are engaged. Then, the attachment screw 35 is inserted into the insertion hole 36 of the first connection member 33 and is inserted into the groove 32 (not shown) formed in the groove 32 of the second attachment surface 30 and the downstream end surface 16 of the regulator 12. Then, the regulator 12 is connected to the body 25 by screwing the attachment screw 35 into the pair of attachment holes 38 of the second connection member 34. As a result, the regulator 12 in which the first protrusion 17A and the second protrusion 17B are formed and the solenoid valve manifold 13 in which no protrusion is formed are connected in a state where the fluid passages 12a and 13a are in communication with each other. Connected via the device 14.

  In the pneumatic control device unit 11 configured as described above, when compressed air as a fluid is supplied from an air supply source (not shown), the pressure is adjusted to a predetermined pressure by the regulator 12, and then the discharge port of the regulator 12. 15 is discharged. The compressed air discharged from the discharge port 15 flows into the communication passage 40 of the body 25, flows through the communication passage 40, and then flows into the supply port 22 of the solenoid valve manifold 13. The compressed air is supplied to a pneumatic actuator (not shown) (for example, an air cylinder) via the solenoid valve manifold 13 so that the pneumatic actuator is activated.

According to this embodiment, the following effects can be obtained.
(1) The body 25 and the regulator 12 are connected using the first connection member 33 and the second connection member 34. The connection plug 28 is inserted through the insertion hole 27 of the body 25 and then screwed into the port 23 to connect the body 25 and the solenoid valve manifold 13. Therefore, even if the projecting portion is not formed on the solenoid valve manifold 13, the regulator 12 and the solenoid valve manifold 13 are connected after the fluid passage 12a of the regulator 12 and the fluid passage 13a of the solenoid valve manifold 13 are connected. be able to. In addition, since the connection plug 28 is not screwed into the supply port 22 of the manifold block 18, even if fluid flows into the supply port 22 of the manifold block 18 from the communication passage 40, the constriction of the connection plug 28 can be seen as in the past. An adverse effect such as a decrease in the flow rate of the fluid more than necessary due to the action can be suppressed.

  (2) In addition to the function of connecting the body 25 to the solenoid valve manifold 13, the connection plug 28 closes the port 23 of the solenoid valve manifold 13, so that a member for closing the port 23 is provided separately from the connection plug 28. It is not necessary to provide it. Therefore, the configuration can be simplified.

  (3) By extending the communication passage 40 so as to be bent, the discharge port 15 of the fluid passage 12a of the regulator 12 and the electromagnetic contact regardless of the positional relationship between the discharge port 15 of the regulator 12 and the supply port 22 of the solenoid valve manifold 13. The supply port 22 of the fluid passage 13a of the valve manifold 13 can be communicated with each other.

(4) Since the seal member 44 is mounted, it is possible to suppress leakage of fluid flowing into the supply port 22 of the solenoid valve manifold 13 from the communication passage 40 to the outside.
(5) Conventionally, the regulator 12 and the solenoid valve manifold 13 are connected using a tube or the like in a state of being separated from each other. However, if the connecting device 14 is used, the regulator 12 and the solenoid valve manifold 13 are connected close to each other. Can do.

The embodiment described above can also be carried out in a form appropriately modified as follows.
A sound deadening material may be provided on the connection plug 28. For example, as shown in FIG. 6, the connection plug 28 may be formed with a hole 51 extending along the axis thereof and penetrating the connection plug 28, and the sound deadening material 50 may be provided in the hole 51. Here, if the sound deadening material 50 is attached to the port 23, the air sound at the time of driving the solenoid valve manifold 13 can be silenced, but when the connection plug 28 is screwed to the port 23, There is a concern that the sound deadening material 50 cannot be mounted and a large air noise is generated from the solenoid valve manifold 13. In this regard, if the connection plug 28 accommodates the silencer 50, the silencer 50 can reduce the volume of air sound generated when the electromagnetic valve 19 is driven.

  The fastening member may be any member that can be screwed into the port 23 and connect the body 25 to the solenoid valve manifold 13, and is not limited to the connection plug 28. For example, as shown in FIG. 7 (a), a cylindrical screw member 60 having a male screw threaded on its outer peripheral surface and a female screw threaded on its inner peripheral surface, and screwed inside the screw member 60. A fastening member may be constituted by the bolt 61. In this case, the body 25 can be connected to the manifold block 18 by the screw-in member 60 and the bolt 61. If the standard of the male screw of the bolt 61 and the standard of the female screw formed in the port 23 are different, a bottomed cylindrical adapter (a plug for closing) is prepared instead of the screw-in member 60. The body 25 may be connected to the manifold block 18 by: In this case, the external thread of the same standard as the female thread of the port 23 is threaded on the outer periphery of the adapter, while the female thread of the same standard as the male thread of the bolt 61 is threaded on the inner periphery. If comprised in this way, even if the specification of the screw of the bolt 61 and the specification of the screw of the port 23 are different, the bolt 61 and the port 23 can be screwed together. Further, as shown in FIG. 7B, the fastening member may be constituted by a nipple 62 in which male screws are screwed into both end portions 62 a and 62 b and a nut 63 that can be screwed into the nipple 62. In this case, first, the nipple 62 is inserted into the insertion hole 27 of the body 25, and then one end 62 a is screwed into the port 23. In addition, the body 25 may be connected to the manifold block 18 by screwing the nut 63 into the other end 62 b protruding from the insertion hole 27.

  The number of fluid pressure devices connected to the body 25 is not limited to two. Three or more fluid pressure devices may be connected to the body 25. For example, as shown in FIG. 8A, a side surface of the body 25 different from the first mounting surface 26 and the second mounting surface 30 is provided. A connection hole 70 may be formed in 25a, and a fluid pressure device different from the regulator 12 and the solenoid valve manifold 13 may be connected to the body 25 via an adapter having a passage. In this case, the connection hole 70 and the port of the fluid pressure device are communicated by the passage of the adapter. When the port of the fluid pressure device is communicated with the communication passage 40 via the branch passage 71 extending from the connection hole 70, the discharge port 15 of the regulator 12, the supply port 22 of the solenoid valve manifold 13, and the port of the fluid pressure device Will communicate with each other.

  ○ The structure of the body 25 may be changed. For example, as shown in FIG. 8B, a detent portion 80 that protrudes from the first mounting surface 26 of the body 25 toward the manifold block 18 may be provided. The detent portion 80 is formed so as to be engageable with the side surface 81 of the manifold block 18. Then, the rotation preventing portion 80 is engaged with the manifold block 18, thereby suppressing the body 25 from rotating relative to the manifold block 18. Therefore, when the connection plug 28 is rotated and screwed into the port 23, it is possible to suppress the body 25 from rotating together with the rotation of the connection plug 28. Therefore, when the connection plug 28 is rotated, the connection plug 28 can be easily screwed into the port 23.

  ○ The cross-sectional area of the communication passage 40 may be changed. For example, the flow passage cross-sectional area of the communication passage 40 may be formed larger than the flow passage cross-sectional area of the fluid passage 12 a of the regulator 12. Further, the flow passage cross-sectional area of the communication passage 40 may be formed smaller than the flow passage cross-sectional area of the fluid passage 13a of the solenoid valve manifold 13.

  ○ The flow path configuration of the communication path 40 may be changed. For example, a communication passage 40 may be formed that extends in an arc and communicates the discharge port 15 of the regulator 12 and the supply port 22 of the solenoid valve manifold 13. Further, for example, if the center of the discharge port 15 of the regulator 12 and the center of the supply port 22 of the solenoid valve manifold 13 are on the same straight line, the outlet port 15 of the regulator 12 and the solenoid valve extend in a straight line. A communication passage 40 that communicates with the supply port 22 of the manifold 13 may be formed.

  The positions of the regulator 12 and the solenoid valve manifold 13 are not particularly limited and may be changed as appropriate. In this case, if the configuration of the communication passage 40 formed in the body 25 is changed according to the change in the positions of the regulator 12 and the solenoid valve manifold 13, the discharge port 15 of the regulator 12 and the supply port of the solenoid valve manifold 13 are changed. 22 can be communicated.

  A fluid pressure device other than the solenoid valve manifold 13 may be connected to the first mounting surface 26 of the body 25. In the case of a fluid pressure device in which a screw hole that can be screwed with the connection plug 28 is formed, for example, a filter may be connected to the first mounting surface 26 or a lubricator may be connected.

  A fluid pressure device other than the regulator 12 may be connected to the second mounting surface 30 of the body 25. In the case of a fluid pressure device having a projection, for example, a filter or a lubricator may be connected to the second mounting surface 30.

  The connecting device 14 can be used not only when connecting the regulator 12 arranged on the upstream side and the solenoid valve manifold 13 arranged on the downstream side. For example, even when the solenoid valve manifold 13 is located upstream and the regulator 12 is located downstream, they can be connected. In this case, the solenoid valve manifold 13 can be connected to the first mounting surface 26 of the body 25 by screwing the connection plug 28 into the port formed on the downstream end face 16 of the solenoid valve manifold 13.

  The number of solenoid valves 19 provided in the solenoid valve manifold 13 is not particularly limited. If the configuration of the fluid passage 13a is changed according to the number of solenoid valves 19 provided in the solenoid valve manifold 13, the number of solenoid valves 19 provided in the solenoid valve manifold 13 may be any number. For example, the number of solenoid valves 19 may be One may be sufficient.

  The first fluid pressure device and the body 25 are not limited to those in which the protrusions are connected by connecting members. Even if the first fluid pressure device does not have a protrusion, for example, when the first fluid pressure device has a port configuration similar to that of the second fluid pressure device, a plug having the same configuration as the connection plug 28 is used. One fluid pressure device can be connected to the body 25.

  The present invention can be applied to, for example, a hydraulic control device unit that constitutes a part of a liquid circuit that circulates liquid, in addition to the pneumatic control device unit.
