[0002]

2. Description of the Related Art A conventional chip processing apparatus used in a cutting machine such as a saw machine will be briefly described.

A chip storage case for storing chips is provided in an oil tank of the cutting machine, and the chip storage case has a chip intake section and a chip discharge section. Here, the bottom side of the chip storage case is configured to be vertically inclined, and the chip discharge section is configured to protrude outside the oil tank. or,
A plurality of communication holes communicating with the oil tank are provided at a lower portion of the chip storage case.

[0004] A screw conveyor is provided in the chip storage case for transporting chips from the chip intake section to the chip discharge section. The screw conveyor includes a rotary shaft rotatably provided in a chip storage case, a spiral spiral provided on the rotary shaft, and a drive motor for rotating the rotary shaft.

[0005] Therefore, the chips generated by the cutting process by the processing section are taken in from the chip intake section and stored in the chip storage case. Then, the chips stored in the chip storage case are transported from the chip intake section to the chip discharge section by the rotating spirals driven by the drive motor, and the chip is discharged from the chip discharge section. It is carried out of the storage case. Here, even if the cutting oil attached to the chips is stored in the chip storage case, the cutting oil is collected in the oil tank through the communication hole.

[0006]

However, when the chips are transported, the cutting oil adhering to the chips may be carried out of the chip storage case together with the chips. As a result, the cutting oil cannot be sufficiently collected, the consumption of the cutting oil increases, and much time and labor is required to separate the cutting oil and the cutting oil carried out of the chip storage case. There is a problem of spending.

[0007]

In order to solve the conventional problems as described above, in the present invention, as a first means, chips generated by work processing by a processing section of a work processing machine are processed. A chip storage case provided with a chip intake section and a chip discharge section, and the bottom side of the chip storage case is configured to be inclined up and down. A communication hole communicating with an oil tank of the work processing machine is provided at a lower portion of the work processing machine, and a screw conveyor for conveying chips from a chip intake portion to a chip discharge portion side is provided, and the screw conveyor is provided with the chip storage case. A spiral motor provided in the inside of the screw conveyor, and a driving motor for rotating the spiral. A screw is formed so that a through hole is formed at the center of the spiral of the spiral when viewed from the tip side of the screw conveyor. The conveyor is configured in a shaftless shape, and a defoaming nozzle that sprays cutting oil into the chip storage case is provided to eliminate bubbles of the cutting oil accumulated in the chip storage case. And

As a second means, in addition to the invention-specifying means of the first means, the defoaming nozzle is branched and connected in the middle of a cutting supply circuit for supplying cutting oil to the processing portion. And

As a third means, in addition to the invention-specifying items of the first or second means, the chip storage case is provided in the oil tank, and the chip discharge portion projects out of the oil tank. The defoaming nozzle is configured to be positioned above the level of the oil in the oil tank.

[0010] By the above means, chips generated by the work processing by the processing section are taken in by the chip intake section and stored in the chip storage case. Then, the stored chips are conveyed from the chip intake section side to the chip discharge section side by the rotating spirals driven by the drive motor,
It is carried out of the chip storage case from the chip discharge section.

Here, even if the cutting oil adhering to the chips is stored in the chip storage case, the cutting oil is collected in the oil tank through the communication hole. In addition, the cutting oil tends to be carried out of the chip storage case together with the chips from the chip discharge side due to the conveyance of the chips, but the cutting oil passes through a through hole formed in the center of the spiral of the spiral. As a result, the cutting oil flows to the lower side in the storage case (the side opposite to the chip discharge side), so that the cutting oil can be suppressed from being carried out of the chip storage case.

Further, when the cutting oil is foamy, the cutting oil is difficult to pass through the through-hole, so that the cutting oil is more likely to be carried out of the chip storage case together with the chip from the chip discharge side. Become stronger. However, when the cutting oil is jetted into the storage case by the defoaming nozzle, the bubbles of the cutting oil are eliminated, and the foamed cutting oil is changed to a liquid cutting oil. Since the liquid cutting oil flows to the lower side in the storage case through the through hole, it is possible to suppress the cutting oil from being carried out of the chip storage case.

[0013] In the case where the second aspect of the present invention is provided, the cutting oil supply circuit can be used as a hydraulic circuit for operating the defoaming nozzle. Can be simplified.
