Description

[Detailed Description of the Invention] This invention relates to a device for separating cutting oil and cutting waste in a bandsaw machine.

In a conventional separation device, an outflow hole for overflowing cutting oil to flow outward is provided in a conveyor case equipped with a screw conveyor that can freely transfer and discharge cutting waste. A storage container for storing chips was removably attached.

However, in order to remove this storage container, it is necessary to first remove the cover and then directly pull out the storage container, which has the drawback that the operation of attaching and removing the container is cumbersome and the work performance during maintenance and replacement work is extremely low.

This invention was devised in view of the above-mentioned drawbacks of the conventional technology, and its purpose is to provide a separation device in which a storage container and a cover are integrated, in order to simplify the operation of attaching and removing the storage container. It is something.

Hereinafter, one embodiment of this invention will be described in detail using the drawings.

FIG. 1 shows a front view of a general horizontal bandsaw machine, in which a saw blade housing 5 is mounted on a base 3 so as to be able to be raised and lowered via a lifting actuator 7, and a loop-shaped saw blade is installed inside the saw blade housing 5. Blade 9
is installed so that it can be rotated freely.

In FIG. 2, a cutting oil tank 11 is provided in the lower part of the interior of the base 3, and a cutout hole 13 is provided at the top of the base 3 through which cutting oil and chips (chips) fall, and directly below the cutout hole 13. There is a chute 14 attached to the.

A so-called cutting waste discharge device 15 is installed between this notch hole 13 and the cutting oil tank 11.

The cutting waste discharge device 15 includes a screw conveyor 17 for transferring cutting waste, a drive device 19 for driving the screw conveyor 17, a conveyor case 21 that rotatably supports the screw conveyor 17, and the like.

The screw conveyor 17 is defined by a screw shaft 23 and screw blades 25, and is inclined so that the height gradually increases from the transfer start end to the transfer end.

As shown in FIG. 4, the bottom surface portion 30 of the conveyor case 21 is formed to have a semicircular cross section, and upwardly inclined inclined walls 39 are provided on both sides of the circular arc cross section.

The bottom part 30 has a discharge hole 29 through which only cutting oil can pass.
．． 29. ... are drilled multiple times.

The conveyor case 21 is attached to the inner wall of the cutting oil tank 11 with a fixing member 35 such as a bolt, with the screw conveyor 17 installed therein.

A long hole 37 is provided in the inclined wall 39 of the conveyor case 21 in a direction parallel to the screw shaft 23, and a discharge guide member 4 is formed so as to cover the inside thereof with an appropriate gap.
1 is provided.

The gap formed between the discharge guide member 41 and the inclined wall 39 forms a communication passage 43 that communicates with the hollow interior of the conveyor case 21, and the communication passage 43 communicates with the outside through the elongated hole 37.

A chute member 45 is provided on the outer side surface of the conveyor case 21 at a lower position of the elongated hole 37 .

A cover 49 integral with a handle 47 is removably provided on the front wall of the cutting oil tank 11, and a plurality of substantially rectangular support members 53, 55 are secured to the cover 49 by fastening members 51 such as bolts. The support members 53 and 55 are tilted and fixed toward the conveyor case 21.
The container 64 is fixed to the outer surface of the conveyor case 21 below the chute member 45 by fastening members 57, 59, 61, and 63 such as bolts.

Inside the storage container 64, a filter member 65 such as a screen is removably housed.

Next, as shown in FIGS. 2 and 5, a rectangular cutting waste removal member 71 is attached perpendicularly to the screw shaft 23 to the screw shaft upper part 67 by a fixing member 69 such as a pin.

With the above configuration, the operation of this embodiment will be explained.

The material to be cut is cut by the saw blade 9, and cutting waste generated during cutting flows into the conveyor case 21 through the notch hole 13 and the chute 14 together with cutting oil.

Among the cutting chips and cutting oil that have flowed into the conveyor case 21, relatively large cutting chips are transferred to the outside of the base 3 via the screw conveyor 17 and are discharged. 29.29. . . flows into the cutting oil tank 11.

At this time, the cutting waste that is wound around the screw shaft upper part 67 and remains in the direction of the drive unit is removed by the cutting waste removing member 71 so as to be brushed off.

Cutting waste and cutting oil pass through the chute 14 to the conveyor case 2
1, due to the action of the discharge guide member 41,
Cutting debris and cutting oil that flow in do not flow outward from the elongated hole 37.

When cutting oil accumulates in the conveyor case 21, relatively small cutting debris floats on the oil level of the accumulated cutting oil, and when the oil level becomes higher than the position of the elongated hole 37, the oil Cutting oil and cutting debris near the surface are discharged into the storage container 64 through the communication path 43, the elongated hole 37, and the chute member 45.

The cutting oil and cutting debris that have leaked into the storage container 64 are filtered and separated by a filter member 65.

Since the storage container 64 is integrally attached to the cover 49, cutting debris that has been filtered and adhered to the filter member 65 can be discharged to the outside very easily.

As can be understood from the above description of the embodiments, the present invention provides the following effects although it is a device for separating cutting oil and cutting waste as described in the claims.

■ The storage container and cover are integrated into one unit, making it easy to attach and remove the storage container.

Furthermore, this invention is not limited to the above-mentioned embodiments, but can be implemented in other forms other than the above-mentioned embodiments.
