On the other hand, if the supply of air from the nozzle 19 is stopped in order to prevent the above problems, the coolant 18 will enter the circuit from the nozzle 19, causing problems such as failure of each detection sensor and clogging of the nozzle 19. arise. In order to prevent the above problem, the supply of coolant 18 is stopped every time the workpiece 17 is removed, but the coolant remaining on the support base 16 becomes atomized and is sprayed up from the nozzle 19, causing a problem.

A pipe line 13 branching from a pipe line 12 connecting the direction control valve 6 and the direction control valve 8 is connected to the low pressure circuit 3. The low pressure circuit 3 is
It is formed from a throttle valve 15 and a check valve 14, and is connected to the filter 9. Therefore, the weak pressure circuit 3 and the air circuit 2
It is placed in parallel with. The low pressure circuit 3 is maintained at a low pressure of, for example, 0.5 kg/cm 2 by adjusting the throttle valve 15 .

力に較べて低圧のため上記機能に影響しない。 First, air supply for checking close contact will be explained. Air passes from the pressure source 1 through the filter 4, and is controlled by the pressure control valve 5 to provide the required high-pressure air (for example, 4 kg/
cm 2 ), and the pressure switch 7 is activated to send it to the pipe 12. The directional control valves 6 and 8 are brought into an air-conducting state by the solenoid, and the high-pressure air is sent through the filter 9 from the pressure control valve 10 to the switch 11. With the switch 11, air is sent to the nozzle 19 of the support base 16 and reaches the contact area 21 where the workpiece 17 is directed. On the other hand, the air that has proceeded from the pipe line 12 to the pipe line 13 passes through the low pressure circuit 3 and is combined with the air circuit from the flow direction control valve 8 at the filter 9. When the workpiece 17 and the support base 16 are in close contact with each other and almost no air leaks from the contact portion 21, the air circuit is kept at a high pressure, and the pressure value confirms the close contact. Note that when the solenoid of the directional control valve 8 is closed, only air from the low pressure circuit 3 flows to the nozzle 19.
Since this air has a lower pressure than the air pressure from the directional control valve 8, it does not affect the above function.

ソレノイドを開にすると弱圧回路３は閉止されな
いためエアは弱圧回路３を通つてノズル１９に達
し、これから排出される。しかしこの排出エアは
弱圧のためクーラント１８は噴霧状態にならな
い。 Next, if the solenoid of the directional control valve 8 is opened before the close contact between the workpiece 17 and the support base 16 is loosened or the workpiece 17 is removed, the low pressure circuit 3 will not be closed, so air will flow through the low pressure circuit 3 and into the nozzle. It has reached 19 and will be discharged from now on. However, since this exhaust air has a low pressure, the coolant 18 is not in a spray state.

口していてもノズル１９の先端から弱圧エアが出

出来る。再び工作物１７が支承台１６に載置され
ると、圧力が上り、圧力スイツチ７により方向制
御弁８がONとなり、所定圧力のエアが供給され
て密着確認が行われる。 Further, even if the workpiece 17 is removed and the nozzle 19 is open, the coolant 18 does not flow into the air circuit 2 because low-pressure air is coming out from the tip of the nozzle 19. Therefore, the equipment in the air circuit 2 is not contaminated with coolant, and clogging and damage to the equipment in the air circuit 2 can be prevented. Furthermore, when machining is not performed, only a small amount of air is supplied, reducing air consumption and reducing power consumption. When the workpiece 17 is placed on the support stand 16 again, the pressure increases, the pressure switch 7 turns on the direction control valve 8, and air at a predetermined pressure is supplied to confirm the close contact.

It is possible to protect air circuit equipment and save power.
