The inner edge of the bottom wall is airtightly attached to the outer peripheral surface of the table 11, and the upper edge of the outer wall of the gutter 18 is
, Which protrudes greatly above the upper surface of the
Then, as the water level rises, the upper surface of the plate glass A submerges.

Thereafter, the valve 21 is closed to stop the supply from the water supply pipe 19, and then the valve 22 is opened to discharge the washing water from the drain pipe 20.

Then, the upper washing water of the glass sheet A is directed to the edge of the glass sheet A and flows into the gutter 18.

At this time, glass chips and glass powder which are formed during the processing of the cutting line by the water flow toward the edge on the plate glass A and remain on the plate glass A are washed away and flow down into the gutter 18.

For this reason, the upper surface of the glass sheet A is washed,
No glass chips or glass powder remains on the upper surface.

The flow rate of the drainage for better (reliably) washing out the glass pieces and powder on the plate glass A may be determined by the diameter and the number of the drainage pipes 20.

A tank 23 is provided as shown in FIG.
And the washing water of the drain pipe 20 is allowed to flow into the tank 23, so that the washing water can be effectively used.

At this time, small glass pieces and glass powder in the tank 23 are prevented from being directed into the gutter 18 by the filter device 25.

Further, when water is supplied into the hollow table 11 through the branch pipe 26 as shown in the figure, the sheet glass A floats due to the water jetted onto the table 11 from the small holes.
It becomes easy to take out the sheet glass A after processing.

Of course, the unnecessary water in the tank 23 is
It flows into the tank 23 from a pipe 27 with a valve 28.

When the cutting line is cut by the cutter 16, the upper surface of the sheet glass A may be submerged.

The nozzle 31 is provided with the cutter 1 in the illustrated case.
6 and one on the rear side in the forward traveling direction.
Although the cleaning water is sprayed toward the cut portion 6, the position and the number of the nozzles 31 are not limited. In short, it is sufficient to wash the small glass pieces and glass powder generated by the cutting by the cutter 16 from the cutting start side edge of the plate glass A to the cutting end side edge.

Of course, similarly to the first embodiment, the flushed water flows into the gutter 18 and returns to the tank from the drain pipe, and is supplied from the tank to the nozzle 31 via a pump and a flexible hose. If you leave it, water can be used effectively.

In the third embodiment of the present invention, diffusion preventing plates 41 are provided on both sides in the running direction of the cutter 16 as shown in FIGS.

As the diffusion preventing plate 41, a soft rubber, resin plate, sponge sheet or the like which does not damage the surface of the glass sheet A is used. As shown in FIG. If the diffusion preventing plate 41 is brought into contact with the upper surface of the sheet glass A when the cutting line is cut by the cutter 16, the lower edge of the diffusion preventing plate 41 is released from the upper surface of the sheet glass A when the traveling body 12 goes back. (Floating).

With the above construction, the cutting line is cut by the cutter 16 and the water flow of the washing by the nozzle 31 is prevented from spreading by the diffusion preventing plates 41 on both sides.
In addition, good flushing becomes possible by increasing the momentum of the water flow.

Of course, scattering of glass pieces and glass powder can also be stopped by the diffusion preventing plate 41.
