A bolt screw 97 is screwed into the screw hole 96 in the joint element 91 on the right side. Further, the joint elements 91 are connected in series by engaging the head of the bolt screw 97 with the side piece 94 of one joint element 91. Then, the through holes 92 of the joint element 91 are connected in series to form a main circulation circuit for compressed air. Further, the control element 90 is connected to another joint surface 91 a of each joint element 91. Then, each control element 90 is communicated with the through hole 92 of each joint element 91, and the compressed air is branched to each control element 90.

However, in the connection unit U described in Patent Document 1, in order to connect the joint elements 91 to each other, the joint surface 91a in which the meniscal window 95 in one joint element 91 is formed, and the screw hole 96 in the other joint element 91. It is necessary to join the joint surface 91a on which is formed. For this reason, when the bolt screw 97 is screwed into the screw hole 96, the bolt screw 97 must be screwed inside the recessed portion 93, and the coupling elements 91 are hardly connected to each other. It was a thing.

The fluid control device block 20 and the joint block 30 can be connected by screwing into the fixing holes 40 a of the two connecting members 40. That is, the screwing operation of the fixing member 43 into the fixing hole 40 a is performed outside the fluid control device block 20 and the joint block 30. Therefore, the fluid control device block 20 and the joint block 30 can be easily connected as compared to the case of performing the connecting operation by screwing the bolt screw inside the block as in the background art. As a result, the fluid control device block 20 and the joint block 30 can be reliably connected, and leakage of compressed air due to poor connection can be prevented.

(2) The components of the pneumatic control device unit 10 are directly connected using the connecting member 40 and the fixing member 43. For this reason, for example, a fluid control device, for example, a fluid control device such as a case where a regulator and a control valve are connected using a tube, a joint, etc., due to mixing of a sealant into the pneumatic circuit at the time of connection, etc. Air leakage due to malfunction or insufficient tightening force at the time of connection can be prevented. Furthermore, since no tube is interposed between the components, the number of locations where the passage cross-sectional area of the flow path changes in the pneumatic circuit can be reduced, and the pressure loss can be reduced.

(3) The components of the pneumatic control device unit 10 are coupled with the connecting

surfaces

24 and 34 in contact with each other using the coupling member 40 and the fixing member 43. For this reason, compared with the case where a tube, a joint, etc. interpose between components, the size reduction of the whole pneumatic circuit can be aimed at, and it arranges pneumatic control equipment unit 10 in the limited installation space.

For this reason, the replacement | exchange operation | work of the needle valve 13 can be performed easily.

(5) The compressed air from the air supply source P can be branched and supplied by the joint block 30 in two directions. Therefore, compressed air can be supplied to each pneumatic circuit from one air supply source P even if two pneumatic circuits are provided in the pneumatic control device unit 10. Therefore, the installation space of the pneumatic control device unit 10 can be reduced as compared with the case where each pneumatic circuit is provided with the air supply source P.

(6) While it is possible to connect the components only by using the connecting member 40 and the fixing member 43, it is possible to release the connection between the components simply by screwing the fixing member 43 from the connecting member 40. . Therefore, the components can be disassembled from the pneumatic control device unit 10 and can be easily maintained and replaced.

(7) When the connection surface 24 of the connection portion 22 in the fluid control device block 20 and the connection surface 34 of the connection portion 32 in the joint block 30 are matched, the groove portion 25 of the fluid control device block 20 and the joint block 30 The groove portion 35 is combined to form a hole through which the fixing member 43 can be inserted. Then, when the fixing member 43 is inserted from the fixing hole 40a of the one fixing member 43 into the hole formed by the

groove portions

25 and 35, the tip of the fixing member 43 is directed to the fixing hole 40a of the other connecting member 40 by the hole. I can guide you. Therefore, by forming the

groove portions

25 and 35 in the connecting

portions

22 and 32, the fixing member 43 can be easily screwed.

More specifically, as shown in FIG. 16, the fluid control device block 82 of the third embodiment has a check valve unit C built in the connection block main body 83. Further, in the connection block main body 83, connection portions 85 projecting in a substantially rectangular plate shape are formed on three side surfaces where the fluid passage 84 opens.

In the connection block main body 83, the direction in which the fluid passage 84 penetrates the connection block main body 83 is the axial direction of the connection block main body 83. In the fluid control device block 82 of this embodiment, the fluid passage 84 extends in the axial direction. On the other hand, a fluid passage 84 is also opened in a direction perpendicular to the direction. That is, the fluid passage 84 is formed to extend in a T shape.

As shown in FIG. 15, in the connection block main body 83, each connection portion 85 is provided on a side surface adjacent to and intersecting (orthogonal) the rear surface 83a and the front surface 83b. Similar to the embodiment, a connection surface 85a, a groove 85b, and a pair of connection projections 85c are formed. Further, a display portion N displaying an “arrow” indicating the flow direction of the compressed air in the fluid control device block 82 is provided on the front surface 83 b of the connection block main body 83.

In addition, as shown in FIG. 16, a part of the fluid passage 84 along the axial direction of the connection block main body 83 is formed in a circular hole shape whose diameter is larger than that of other portions in the fluid passage 84, and the diameter is increased. A valve chamber 79 is defined in the region. The valve chamber 79 is formed to extend in a circular shape along the axial direction of the connection block main body 83. A valve seat 78 is formed on the inner surface of the connection block main body 83 that forms the valve chamber 79, and on the peripheral edge of the fluid passage 84 that opens toward the valve chamber 79.

A check valve unit C is accommodated in the valve chamber 79. The check valve unit C is configured to hold the valve body 73 and the valve body 73 integrally, and to position the valve guide 74 in the valve chamber 79. The cap 75 is mounted in the fluid passage 84, and a biasing member 76 that biases the valve guide 74 toward the valve seat 78. A cylindrical guide portion 74 a is formed on the outer periphery of the valve guide 74. The guide portion 74 a is in sliding contact with the inner peripheral surface of the valve chamber 79 and guides the valve guide 74, that is, the valve body 73 so as to move along the axial direction of the connection block main body 83. Further, the valve guide 74 is formed with a communication hole (not shown) that allows the inside of the valve chamber 79 and the inside of the valve guide 74 to communicate with each other.

The urging member 76 is formed of a coil spring, and the urging member 76 is disposed inside the guide portion 74 a in the valve guide 74. The biasing member 76 has one end in contact with the valve guide 74 and the other end in contact with the inner end surface of the cap 75, and the biasing member 76 is in contact with the valve body 73 until a fluid pressure higher than a predetermined pressure is applied. The valve body 73 is seated on the valve seat 78 by the biasing.

As shown in FIG. 17, an engagement groove 75 a is recessed in the outer peripheral surface of the cap 75 over the entire circumference of the cap 75. Further, in the connection block main body 83, an insertion hole 83c extending in the vertical direction so as to sandwich the fluid passage 84 is formed on the opening side of the fluid passage 84 from the valve chamber 79. In a state where the cap 75 is accommodated in the fluid passage 84, both sides in the radial direction and the insertion holes 83 c of the connection block main body 83 communicate with each other in the engagement groove 75 a of the cap 75. When the U-shaped retaining pin 70 is inserted into the insertion hole 83 c of the connection block main body 83, the prevention pin 70 is inserted into the engagement groove 75 a of the cap 75 and the insertion hole 83 c of the connection block main body 83. As a result, the cap 75 is prevented from coming off in the fluid passage 84, so that the cap 75 is mounted in the fluid passage 84.

Further, as shown in FIG. 16, in a state where the cap 75 is prevented from coming off in the fluid passage 84, an O-ring 77 is disposed between the outer peripheral surface of the cap 75 and the inner peripheral surface of the fluid passage 84. The O-ring 77 suppresses fluid leakage from between the outer peripheral surface of the cap 75 and the inner peripheral surface of the fluid passage 84.

Then, in the fluid control device block 82 of the present embodiment, when compressed air is supplied from one of the two openings of the fluid passage 84 facing in the axial direction (left side in FIG. 16), the fluid pressure is equal to or higher than a predetermined pressure. Until the valve element 73 acts on the valve element 73, the valve element 73 is seated on the valve seat 78. For this reason, compressed air is not supplied to the other side of the fluid passage 84 (to the right in FIG. 16), and fluid is supplied to the fluid passage 84 extending in a direction orthogonal to the axial direction of the connection block main body 83. ing. When a predetermined fluid pressure is applied to the valve body 73, the valve guide 74 moves and the valve body 73 is separated from the valve seat 78. Then, the compressed air flows into the valve chamber 79, and the compressed air flows into the valve guide 74 from the communication hole of the valve guide 74. The compressed air is supplied from one opening of the fluid passage 84 to the other opening.

In the fluid control device block 82, when compressed air flows backward from the other of the two openings (the right side in FIG. 16) of the fluid passages 84 facing in the axial direction of the connection block body 83, the valve guide 74 receives the fluid pressure. Moves toward the valve seat 78, and the valve body 73 is seated on the valve seat 78. For this reason, the backflow of the compressed air to one opening side of the fluid passage 84 is prevented.

As shown in FIG. 18, in the fluid control device block 82 including the check valve unit C shown in FIGS. 15 to 17, even if the pressure indicator 72 for displaying the fluid pressure in the fluid passage 84 is provided integrally. Good.
