[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coolant device, and more particularly, to a coolant device capable of preventing a coolant recovered together with chips from a machined portion of a machine main body from scattering outside.

[0002]

2. Description of the Related Art In a conventional coolant apparatus, a chip bucket is configured to be movable in a horizontal direction on a tank for storing coolant so that chips collected in a chip bucket can be easily taken out, and chips are taken out. Sometimes, the tip bucket can be pulled out. Therefore, the lower end portion of the chip discharge port of the machine body and the chip chip receiving port of the chip bucket are provided with a required gap in the vertical direction.

[0003]

For this reason, when chips and coolant are collected in the chip bucket, the splashes of the coolant hitting on the bottom surface of the chip bucket or the collected chips cause vertical movement between the machine body and the chip bucket. It may be scattered outside through the gap in the direction. There is a problem that there is a danger that the floor surface is stained by the scattered coolant or that the worker slips on the foot with the scattered coolant.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to facilitate the discharge of chips and to prevent the coolant from splashing. It is an object of the present invention to provide a coolant device capable of preventing the occurrence of the coolant.

[0005]

In order to achieve the above object, a coolant device according to the present invention is provided outside a machine main body and stores a coolant to be supplied to a processing section, and the tank is used for processing the coolant. A pump that supplies a coolant to the part, and a coolant device that includes a chip bucket that collects chips discharged from the processing part,
A buoy floating in the coolant is provided in the tank, and the chip bucket is supported by the buoy.

In addition, a valve for switching to two directions is provided at the discharge port of the pump, and a spare tank for temporarily retreating the coolant stored in the tank when lowering the buoy is provided at one discharge port. preferable.

[0007]

After the chip bucket is set on the tank for storing the coolant, the coolant is supplied from the spare tank into the tank to increase the amount of the coolant in the tank. Then, the buoy is levitated by increasing the amount of the coolant.
Then, the chip bucket is pushed upward by the buoy, and the discharge port of the machine body is covered with the receiving port of the chip bucket. By covering the discharge port of the machine body with the receiving port of the chip bucket in this way, it is possible to prevent the coolant from scattering.

[0008] Chips discharged from the machine body fall onto a chip bucket and are collected. Then, when a large amount of chips is collected on the chip bucket, when processing of the machine main body is stopped, the pump is operated to discharge the coolant in the tank to the spare tank. Then, the buoy descends and the tip bucket also descends. Accordingly, a vertical gap is formed between the discharge port of the machine body and the receiving port of the chip bucket, thereby enabling the chip bucket to move in the horizontal direction. Then, the chip bucket is pulled out and the chips are discarded.

Accordingly, the coolant does not scatter from the vertical gap between the machine body and the chip bucket, and the chips can be easily discharged.

[0010]

Embodiments of the present invention will be described below. 1 and 2 show one embodiment of a coolant device according to the present invention.

In FIG. 1, reference numeral 1 denotes a coolant device which is arranged below the machine main body 2. 2 is the machine body,
3 is a chip bucket. The chip bucket 3 serves as a tray for receiving chips 4 generated by cutting the machine body 2 and coolant supplied during cutting. Reference numeral 5 denotes an arm fixed to the chip bucket 3, and a caster 6 is attached to a lower end of the arm 5. The caster 6 is configured to roll on the floor 20. Therefore, the tip bucket 3 can be pulled out by the casters 6 as shown by the arrow A in FIG. Reference numeral 7 denotes a punching metal, and chips 4 generated by cutting the machine body 2.
Drops into the chip bucket 3 in a state of being mixed with the coolant supplied at the time of cutting, so that only the coolant is filtered from the discharge mixed with the chips 4. Reference numeral 8 denotes a tank placed on the floor surface 20 for storing the coolant 9 to be supplied to the processing section. 10
Is a buoy floating on the coolant 9 stored in the tank 8. The buoy 10 has a sealed structure having a capacity to generate a buoyancy larger than the weight of the chip bucket 3 and the chips 4 collected in the chip bucket 3. 11 is
A pump attached to the tank 8, the pump 1
Reference numeral 1 denotes an operation for supplying the coolant 9 stored in the tank 8 to a processing section or a spare tank (not shown), or supplying coolant from the spare tank. 1
Reference numeral 2 denotes a valve attached to a suction / discharge port 13 provided in the pump 11. By switching the valve 12, one is connected to the machine body 2 and the other is connected to a spare tank (not shown).

Next, the operation of this embodiment will be described.
First, move the tip bucket 3 to the upper part of the tank 8,
By operating the pump 11, the coolant 9 is sucked from the spare tank and supplied to the tank 8.
Increase the amount of. Then, the buoy 10 is levitated by increasing the coolant 9. Then, the chip bucket 3 is pushed up by the rise of the buoy 10, and the discharge port of the machine body 2 is covered with the receiving port of the chip bucket 3.
At this time, the discharge port of the machine body 2 and the receiving port of the chip bucket 3 overlap by a distance a in the vertical direction. By covering the discharge port of the machine main body 2 with the receiving port of the chip bucket 3 in this way, it is possible to prevent the coolant 9 from scattering.

The chips 4 discharged from the machine body 2 fall onto the chip bucket 3 and accumulate. When a large amount of chips 4 accumulates on the tip bucket 3, when the machining of the machine body 2 stops, the pump 11 is operated to temporarily discharge the coolant 9 in the tank to the spare tank, The amount of the coolant 9 is reduced. Then, the buoy 10 descends due to the decrease in the coolant 9, and at the same time, the tip bucket 3 descends. Then, the caster 6 attached to the lower end of the arm 5 of the chip bucket 3 comes into contact with the floor surface 20 and the chip bucket 3 is lowered until the caster 6 supports the entire weight of the chip bucket 3. Then, the vertical gap between the machine body 2 and the chip bucket 3 is a distance b at which the upper end of the chip bucket 3 does not contact the lower end of the machine body 2 when the chip bucket 3 is moved in the horizontal direction. Therefore, the chip bucket 3 is pulled out in the horizontal direction as shown by an arrow A shown in FIG.

Therefore, according to the present embodiment, the coolant is not scattered from the vertical gap between the machine main body and the chip bucket during machining of the machine main body, and the chip bucket is pulled out in the horizontal direction and the chips are removed. To take out
Chips can be easily discharged.

[0015]

[Effect of the Invention] The present invention raises and lowers the buoy that floats on the coolant and enters and exits from the upper end of the tank by increasing or decreasing the amount of coolant in the tank that stores the coolant to be supplied to the machine body installed outside. Since the bucket is configured to be movable in the vertical direction, chips can be easily discharged, and splashing of coolant during machining of the machine main body can be prevented. A two-way valve is provided at the discharge port of the pump, and a spare tank that temporarily retracts the coolant stored in the tank when lowering the buoy is provided at one of the discharge ports. Supply can be made.
