In addition, a partition wall 16 is installed in the middle of the cylinder 12 to form chambers 12a and 12b separated from right and left by the partition wall 16, and air supply pipes 17 and 18 are respectively provided in the chambers 12a and 12b. ) Is piped so that one air supply pipe 17 supplies air to the left chamber 12a among the left and right chambers 12a and 12b, and the other air supply pipe 18 to the right chamber 12b. The air is supplied, and the pistons 19 and 20, which may slide left and right on the left and right chambers 12a and 12b, are connected to the sleeve 21 passing through the center of the partition wall 16.

In addition, the partition wall 16 is alternately pumped through the left and right chambers 12a and 12b through the cutting oil inlet pipe 15 so that check valves 22a and 22b may be intermittently supplied to the cutting oil supply pipe 9. On the partition 16, it is provided so that a supply interruption may be made in the opposite direction to the cutting oil inflow hole 22a 'and the cutting oil supply hole 22b' which are made of a T-shape.

The check valve 22b of the cutting oil supply hole 22b 'is to use a one-way check valve to allow the cutting oil to be discharged from the chambers 12a and 12b.

And the water supply pipe 10 is connected to the tap water supply pipe 23 to supply the water into the cutting oil mixing tank (2), in order to control the supply of the water supply pipe (10) in the middle of the electromagnetic open and close valve (24) In addition, the electromagnetic opening and closing valve 24 automatically cuts off the water supply when the water inside the cutting oil mixing tank 2 becomes full.

The mixed oil supply pipe 25 is connected to the cutting oil mixing tank 2 at the bottom of the cutting oil mixing tank 2 so that the cutting oil and water mixed in the cutting oil mixing tank 2 may be mixed oil and supplied to the mixed oil storage tank 1. The solenoid opening and closing valve 26 is connected to the mixed oil supply pipe 25, and the solenoid opening and closing valve 26 is automatically brought to a minimum level of the mixed oil by a sensing means 7 installed inside the cutting oil mixing tank 2. To be closed.

The detection means 7 is a cutting oil detection sensor 27 that can detect the presence of cutting oil and the cutting oil mixing tank (2) when the cutting oil and water are mixed and discharged into the mixed oil storage tank (1) The mixed oil lowest level sensor 28, which can sense the lowest water level, and the full level sensor 29, which can detect the state of the high level of the mixed oil mixed with the cutting oil and the water, are respectively installed.

The mixed oil supply control means 6 for supplying the cutting oil and water to the cutting oil mixing tank 2 at a predetermined ratio and supplying the mixed oil storage tank 1 using air pressure to supply air to the cutting oil mixing tank 2. The air supply pipe 30 for supplying is installed with the pressure regulating valve 31, and the mixed oil supplied from the cutting oil mixing tank 2 to the mixed oil storage tank 1 through the mixed oil supply pipe 25 by air pressure. Floating valve 32 is installed to automatically shut off the mixed oil supply from the cutting oil mixing tank (2) when the high water level.

In addition, a solenoid valve 33 for intermittently supplying air supplied from a separately installed air compressor (not shown) to the left and right chambers 12a and 12b of the cutting oil pumping means 4 is installed and connected to an air hose to the corresponding part. It becomes piping.

In addition, a control box 34 is installed on the cutting oil mixing tank 2 so that the number and time of pumping can be arbitrarily set when the cutting oil is pumped by the cutting oil pumping means 4 and the cutting oil detecting sensor 27. By interlocking with each other, when the coolant is exhausted in the coolant replenishment tank 3, an abnormality occurs in the coolant supply pipe so that the coolant may be notified when the coolant is not normally supplied.

Reference numeral 35 in the figure shows a safety valve.

The present invention, which can be configured as described above, pumps the cutting oil by the cutting oil pumping means 4 in the cutting oil refilling tank 3 and supplies the cutting oil to the cutting oil mixing tank 2, and then through the water supply pipe 10. Water is supplied to the cutting oil mixing tank (2) to form cutting oil by mixing the cutting oil and the water by the vortex action, and then automatically supply the mixed oil storage tank (1) through the mixing oil supply pipe (25) using air pressure. As a result, its specific action will be described in more detail below.

The operator sets the number and time of pumping the cutting oil pumping means 4 in the control box 34 in advance to set the mixing ratio of cutting oil and water. If the coolant is set to 5 by the volume ratio, since the water is mixed to 100, the coolant pumping means 4 may set the pumping frequency to 5 times assuming that the pumping pump 1 pumps 1 by the volume ratio.

And when the volume ratio of the water mixed with the cutting oil is produced in advance to the volume of the cutting oil mixing tank (2) to supply the water to the water level when the water level is low level sensor 29 detects the water level to cut off the water supply Therefore, the mixing ratio can be automatically adjusted.

When the mixed oil storage tank 1 is initially assumed to be empty, and the mixed oil and the water are mixed to supply the mixed oil to the mixed oil storage tank 1, first, the cutting oil supply pipe piped to the cutting oil supplement tank 3 ( The coolant pumping means 4 on 9) is driven to quantitatively supply the coolant to the coolant mixing tank 2.

That is, the air supplied from the air compressor alternately passes through the air supply pipes 17 and 18 to the chambers 12a and 12b formed to the left and right of the cylinder 12 of the cutting oil pumping means 4 by the operation of the solenoid valve 33. Supply is made.

When air is supplied to the left chamber 12a through the air supply pipe 17, the piston 19 slides to the right by air pressure, and the piston 20 of the right chamber 12b connected to the sleeve 21 also moves to the right. The slide chamber is moved to the right chamber 12b so that a vacuum pressure is generated and the right check valve 22a on the cutting inlet hole 22a 'is opened, and stored in the cutting oil replenishment tank 3 through the cutting inlet pipe 15. When the coolant flows into the right chamber 12b and the air is supplied to the air supply pipe 18 next, the coolant flowed into the right chamber 12b while the piston 20 of the right chamber 12b slides to the left is cut oil. The right check valve 22b on the cutting oil supply hole 22b 'in communication with the supply pipe 9 is opened and is supplied to the cutting oil mixing tank 2 through the cutting oil supply pipe 9.

As such, when the air is alternately supplied to the chambers 12a and 12b formed to the left and right of the cylinder 12 through the air supply pipes 17 and 18, the pistons 19 and 20 are formed together with the sleeve 20. While operating the slide on the 12a, 12b, the vacuum pressure acts alternately on the left and right chambers 12a, 12b while supplying the cutting oil to the cutting oil mixing tank (2) through the suction and the cutting oil supply pipe (9), the cutting oil mixing tank (2) When cutting oil is supplied to the cutting oil), the cutting oil detection sensor 27 detects the presence of the cutting oil and detects the absence of the cutting oil so that the solenoid valve 33 is stopped and the cutting oil supply is automatically stopped.

On the other hand, even when the coolant is exhausted in the coolant replenishment tank 3 in the cutting oil supply process, the coolant pumping means 4 pumps a predetermined number of times, and when the coolant sensor 27 does not detect the coolant, the coolant The control signal is applied to the solenoid valve 33 so that the supply is stopped. As a result, the operation of the coolant pumping means 4 is interrupted and the coolant supply is interrupted and the operator is notified by an alarm sound or the like. ) Is replaced with a new one.

Inside the cutting oil mixing tank (2) through the nozzle 11 of the water supply pipe (10) while the electromagnetic opening and closing valve 24 installed in the water supply pipe (10) connected to the tap water supply pipe (23) for the water supply to the next Water is supplied in an inclined downward direction in the arc direction and is mixed while causing a vortex action together with the coolant supplied in advance.

When the water level is gradually mixed with the water supply and the cutting oil, and reaches the full water level, the full water level sensor 29 is detected to close the electronic open / close valve 24 for supplying water.

And since the mixed oil storage tank (1) is empty as assumed in the electricity, the floating valve 32 is opened, the mixed oil is the cutting oil mixing tank through the air supply pipe 30 while the pressure control valve 31 is opened The cutting oil supplied to (2) and mixed with water by air pressure is supplied to the mixed oil storage tank 1 through the mixed oil supply pipe 25, and floats when the mixed oil reaches the full oil level in the mixed oil storage tank 1 When the valve 32 is angularly moved by buoyancy, the valve is closed and the supply of the mixed oil is automatically terminated. When the mixed oil mixed in the cutting oil mixing tank 2 is supplied to the mixed oil storage tank 1 and reaches the lowest level, the mixed oil is lowest. The water level sensor 28 detects this, and the supply of the mixed oil is stopped regardless of whether the floating valve 32 is opened, and the air supplied to the cutting oil mixing tank 2 is also stopped at the same time.

That is, when the mixed oil lowest level detection sensor 28 detects the lowest level of the mixed oil, the electromagnetic opening and closing valve 26 is closed, so that the mixed oil storage tank through the mixed oil supply pipe 25 in the cutting oil mixing tank 2 is used. The supply of the mixed oil which has been supplied to (1) is stopped, and when the cutting oil pumping means 4 is operated to supply the cutting oil as described above, the process of supplying and mixing the water is repeated, and the mixed mixed oil When the full water level is reached, the mixed oil is supplied to the mixed oil storage tank 1 by air pressure.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the protection scope of the present invention should not be limited to the described embodiments, but should be defined by equivalents as well as the following claims.
