The first type shown in FIGS. 6 and 7 has a drain hole 5 on the side surface of the conveyor machine frame 4 of the chip conveyor 3 which is installed on the punching plate 2 of the cutting water tank 1. The chip is punched and collected in the chip bucket 6 from the discharge port of the conveyor machine frame 4, and the chips dropped on the conveyor are discharged on the conveyor. The cutting water passes through the gap of the hinge and is discharged from the drain hole 5 and collected in the cutting water tank 1. However, the fine chips that are not discharged by the hinge plate conveyor flow into the cutting water tank 1 together with the cutting water and form a sludge. Maintenance is very troublesome because the tank must be collected and cleaned regularly.

The second type shown in FIG. 8 is a hinge plate type chip conveyor 3 having a drainage hole 5 on the side surface of the conveyor frame 4.
The cutting water placed on the shooter 8 and passing through the gap between the hinges and flowing out from the drain hole 5 flows on the shooter 8 and flows into the sub-chip bucket 10 in the cutting fluid tank 1 provided outside the machine. Further, a pipe 9 branched from a part of the cutting water sent from the cutting water pump 7 to the cutting site is supplied to the chip flow on the shooter 8. For this reason, there is an inconvenience that minute chips are deposited on the shooter 8 to impair the flow of cutting water and leak to the floor surface to be contaminated. Also, since the amount of chips discharged to the sub-chip bucket is large, the sub-chip bucket 1
There is a problem that maintenance is required to remove sludge and chips, which is 0, and the burden on the operator increases. The present invention has been made in view of the above problems of the prior art, and an object thereof is a chip treatment capable of easily discharging from minute chips to large curled chips and sludge. It is intended to provide a device.

[0005]

In order to achieve the above-mentioned object, the present invention provides a hinge plate type chip conveyor in which a drainage hole is formed in the bottom of a frame before the conveyor rises, and a chip under the drainage hole. A scraper type chip conveyor having a receiving port, and a guide member which is provided in the scraper type chip conveyor upper portion and causes cutting water to flow out of the frame through a filter,
The sludge receiving box provided in the cutting water tank, and a chip bucket that collects the chips conveyed by the hinge plate type chip conveyor and the scraper type chip conveyor are included, and large chips are fine chips with the hinge plate type chip conveyor. The scraper type chip conveyor is used for discharge processing.

[0006]

[Function] Although large chips are removed by the hinge plate type chip conveyor that circulates in the clockwise direction, small chips adhering to the hinge plate and minute chips that have passed through the gap are not removed here, and the cutting chips are used together with the cutting water to convey the frame. Of the scraper type chip conveyor placed below the water drain hole on the bottom of the
The cutting water is stored in the conveyor frame, and the cutting water that has passed through the filter provided on the upper part of the conveyor flows down into the sludge box to deposit sludge. Overflowing cutting water is returned to the tank. On the other hand, a scraper type conveyor that circulates counterclockwise scrapes off the fine chips adhering to the back surface of the filter and scrapes up the fine chips accumulated at the bottom and discharges them to the chip bucket.

[0007]

Embodiments of the present invention will be described below with reference to FIGS. A lathe is a machine tool that now produces cutting chips. Lathe Lathe 21 is provided with a chip 22 which is attached to a main shaft of the main machine 21 and is provided with a chuck 22 below a machining position of a workpiece to be held.
A known hinge plate type chip conveyor 23 having a chip receiving portion surrounded by and discharging the chips to the outside of the bed is installed. The hinge plate chip conveyor 23 is supported by high legs 24 in a high-floor type, and is supported on the sprocket supported above the chip discharge port 29 of the conveyor machine frame 25 and on the inflection parts of the other end and the middle part. Endless hinge plate conveyor 27 hung on a step by a sprocket
Is rotated by a motor in the clockwise direction in FIGS. 1 and 3.

A drain hole 28 is formed in the bottom of the hinge plate conveyor 27 before the rising portion.
