In other words, the Zi member 132 is made of The operator presses down with his finger to lower the valve 44 that forms an integral part. It is confirmed that the main yam 74a has entered an operating state and leads to a passage 130, a pilot chamber 152a and a hole 134 are all thinned with each other through the vacuum feed device 24a of the structure described above, and the operation mode will be described later. , The compressed air feed source that is not out of the center, such as a compressor, is energized to guide the compressed air through the Huai feed port 32 of the valve unit 10a and the inside of the valve mechanism 26 Therefore, the third port 82a of the first solenoid valve control pilot valve 64 can be reached. When the solenoid coil control valve 70a is disabled, the third port 82a and the fourth port 84a are connected (refer to Figure 0) . Therefore, the pressurized fluid first passes through the fourth port 84a, and then, through a passage 128, reaches the first pilot chamber 56 of the feed valve 40, and thus, the feed valve 40 is closed (refer to U-page>.

When an operation is attracted by a suction block and fed to a desired position, the solenoid control valve 70a is energized. More specifically, A moving iron or moving member 138 moves upward to a seat 140 in the upward direction. Therefore, it can be separated from a valve seat 142. Therefore, the first passage 136 is composed of a passage 144 and an annular space 146 Connected to the third passage 148 (refer to FIG. 5). As a result, compressed air is sent to the third passage 14 8. Then, the pilot chamber 152a is reached by forming a lower part of the hole 134 and an opening or bore 150 around the control member 132, so that the main hip 74a can be moved in the right M direction in the drawing (reference (Figure 5) "until this time. The air in the pilot chamber 90a of the end plate 76a can go from the hole 92 to the pilot 90b of the second solenoid coil control pilot valve 66.

Displacement (Figure 1). In other words, the valve body 44 is displaced in the direction of the left example, so that the third elastic ring 54 is separated from its valve seat 46, so that the spaces 60, 62 can be guided to communicate with each other, so that the feed Lang 40 can be opened (refer to (Figure 4). Until this time, the air in the first pilot chamber 56 can be introduced into the fourth port 84a through the passage 128, and therefore, can be discharged into the exhaust port 36 through the fifth port 86a (refer to FIGS. 5 and 11) ). Since the feed valve 40 is opened in this manner, the feed port 30 of the valve unit 10a and the ejector 16 are communicated with each other (Figure 3). Therefore, a vacuum is developed in the ejector 16, so that the outlet valve 116 made of a condensable material can be opened to allow a suction block to suck in or oil into the air, so that an operation can be attracted or maintained. In other words, the air on the side of the vacuum port 96 can flow into the filter body 122 for removing dust and pass through the passage 118 to open the ihP valve U6, and thereafter, the air passes through the vacuum generator unit 106 and thus can be used by the diffuser 104 inhaled. At this point, the vacuum opening 110 of the pressure detection unit 18 can measure a vacuum degree developed in the vacuum port 96 through the passage 1 extending from the seizure opening 96 and communicate with the pressure tide detection unit 18 Therefore, an output signal with a vacuum degree can be generated.

The Ministry of Economic Affairs, the Ministry of Economic Affairs, the Ministry of Economic Affairs and the Ministry of Industry and Fisheries cooperated with Du Yin M. The compressed air sprayed or discharged from the nozzle 102 enters the diffuser through the muffler 108 and falls outside (refer to Picture 2). Then, after work After feeding, the work is separated from the suction block as described below. In more detail, the first solenoid coil controls the solenoid valve control valve 70 of the pilot valve 64, and the second solenoid The solenoid control valve 70b of the coil control pilot valve 66 and the solenoid control valve 70c of the third solenoid coil control pilot valve 68 are energized. When the first coil control solenoid valve controls the solenoid valve 64 When 70a is de-energized, the moving iron 1 3 8 is displaced downward. Therefore, the seat on the upper part is brought into contact with the valve seat 142, thus making the second passage 154 and the third passage 148 is connected (refer to FIG. 10). On the other hand, when the solenoid control valve 70b of the second solenoid control pilot valve 66 is energized, it flows from the third port 82a of the valve seat portion 72b The constricted air in a passage 13R arrives through the passage 130 and the piercing hole 34 The three-way 148 is the same as the solenoid control valve 70a (refer to the 12th country U. In addition, compressed air flows into the through hole 88 of the main body 74b through an opening 150, and passes through the hole 92 in the pilot chamber 90b of the end plate 76b The first solenoid coil control pilot valve 64 is reached in the pilot plate 90a of the end plate 76a, so that the main body 74a of the first solenoid coil control pilot valve 64 is displaced in the direction of the left mist (refer to FIG. 10).

Therefore, the first electromagnetic The main valve 74a of the coil-controlled pilot valve 64 is on the left side (displaced in the direction to cause the third port 82a and the fourth port Ma to pass through and allow the second port 80a to communicate with the first port 78a (reference FIG. 10 Therefore, the pressurized fluid supplied to the third port 82a can flow from the fourth port 84a into the first pilot chamber 56 via the passage 128, and thus the feed valve 40 is willing to close (refer to FIG. 1). Up to this time, the air in the second pilot chamber 58 flows into the second port 80a through the passage 160. In addition, the air passes through the first port 78a to reach the discharge port 36 of the valve unit unit. Therefore, it can be discharged from the discharge port. Therefore, compressed air is no longer supplied into the ejector 16, and no vacuum is supplied into the suction block (refer to country 3). When the thunder energy is added to the solenoid control valve 70c of the third solenoid control pilot valve 68, the third port 82c of a valve seat portion 72c flows into the first of the solenoid control valve 70c through a passage 130. The constricted stroke in the passage 136 is similar to the case of the first solenoid control valve 70a, and the third passage 148 can be reached (refer to FIG. 7). In addition, the condensed air can flow into a pilot chamber 152c through an opening 150 of a mixing member 132.

In the above-mentioned manner, the compressed air that reaches the ends of the main body 74c is due to the difference between the two ends of the surface of the main body 74 (in the area of the control member Ϊ 32 «7 on the surface of the end plate 76c Zhen), so the generated S forces are also different from each other. Therefore, the main body 74c of the third electromagnetic coil control pilot Lang 68 is displaced in the right direction of the drawing (refer to FIG. 7). Therefore, as a result of the third solenoid coil controlling the displacement of the main body 74c of the pilot valve 68 in the right steel direction in the figure, the third port 82c communicates with the second port 80c and allows the fourth port 84c and the fifth port 86c to communicate . Therefore, the remaining pressurized flow supplied to the third port 82c can flow from the second port 80c into the second pilot chamber 166 via a passage 164, and thus, the vacuum interrupter valve 42 can be opened (refer to circle 11). Until this time, the pressurized fluid in the first pilot chamber 168 can flow into the fourth port 84c through a passage 170, and then can reach the discharge port 36 through the fifth port 86c, and thus can be discharged from the discharge port. Compressed air flows from the vacuum interrupter 34 of the valve unit 10a through the vacuum interrupter valve 42 into the vacuum port < 6, therefore, the vacuum received by the suction block can be released immediately, so the work piece is removed from the suction block Separation of the upper part (refer to the third circle). After the workpiece has been debris from the suction block, while the workpiece is being sucked by the suction block again, the solenoid control valve 70c of the third solenoid control pilot valve 68 is disabled. In the case of the solenoid control valve 70a, the moving iron 138 of the solenoid control valve 70c moves downward.

Since the "dense member 172 also moves downward in a lower position, The second passage 54 communicates with the third passage 148. Due to the ratio, the compressed air cannot be supplied from the third passage 148 to a pilot chamber 152c through an opening 150. In addition, since the compressed air is from a throat portion 72c The third port 82c flows into the pilot chamber 90c of one end plate 76c through a passage 130, so the main diaphragm 74c is displaced in the left direction of the diaphragm surface (refer to FIG. 14C, the third solenoid coil controls the pilot valve 68 The main body 74c is displaced in the reverse left direction in the figure, causing the third port 82c and the fourth port 84c to drop continuously and causing the second port 80c to communicate with the first port 78c. Therefore, the calender supplied to the third port 82c Fluid flows from the fourth port 84c into the first pilot of the vacuum interrupter valve 42 through the passage 170 168, the main body 74c is displaced in the right planing direction of the drawing, so the vacuum cutoff valve 42 is closed (refer to the first cultivating at this time, the air in the second pilot chamber 166 reaches the air via the passage 1M The second port 80c then passes through the first port 78c to reach the discharge port 36.
