Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for draining water droplets remaining on an edge of a glass sheet used in the electronic industry and various other applications when the glass sheet is washed.

[0002]

2. Description of the Related Art In the conventional cleaning of a flat glass, cleaning water is sprayed from a nozzle onto the plate surface of the running flat glass while the flat glass is running, thereby performing cleaning.

A high-pressure air for drying is sprayed from a nozzle onto the surface of the glass sheet onto which the washing water has been blown, and then the glass is dried.

[0004]

According to the above-described cleaning method for plate glass, the cleaning water sprayed on the plate surface of the plate glass is scattered by high-pressure air jetted from a nozzle so that water droplets remain (dry state). ). That is, draining can be performed.

[0005] However, the opposite side (rear side) of the sheet glass in the running direction is in an air pocket state, so that the washing water adhering to the surface on the opposite side edge in the running direction is not scattered but remains.

[0006] For this reason, complete drainage cannot be performed. In other words, residual washing water causes stains during the next processing or during temporary stock before being supplied to the next processing,
There were problems such as defective products.

SUMMARY OF THE INVENTION It is an object of the present invention to perform drainage in which cleaning water does not remain on the side opposite to the running direction of a sheet glass (a peripheral surface or the like).

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a transfer device provided to transfer a sheet glass, and sprays washing water onto a plate surface of the plate glass transferred by the transfer device. In the cleaning of the plate glass composed of the washing nozzle provided as described above and the drying nozzle provided so as to dry the cleaning surface by jetting air, a downstream end of the traveling plate glass from one end on the opposite side in the running direction is provided downstream of the drying nozzle. A configuration is employed in which a water draining nozzle for jetting air that moves sequentially along one end direction and moves forward and backward by appropriate traveling means is provided.

Embodiments of the present invention will be described with reference to the accompanying drawings.

In the embodiment of the present invention, FIGS.
As shown in FIG. 1, reference numeral 1 denotes a sheet glass A transport device.

In the drawing, the conveying device 1 has a roller conveyor 2 with a drive function for receiving the lower edge of the plate glass A in the upright position, and the stable position of the plate glass A to be transported in the upright position. Plate glass A to maintain
And a plurality of upper and lower free-rotating rotors 3 supporting the plate surface.

The roller conveyor having a drive function may be performed by a method in which a sprocket is provided on each roller shaft and an endless chain running by a motor is engaged with each sprocket (not shown).

A cleaning water is sprayed (sprayed) from the cleaning nozzle 4 onto the plate surface of the plate glass A to be transferred by the transfer device 1 to wash the plate surface of the plate glass A.
The high-pressure air from the drying nozzle 5 disposed on the downstream side of the nozzle is blown (sprayed) to dry the cleaning plate surface of the plate glass A.

The cleaning nozzle 4 uses a single closed pipe that crosses the glass sheet A in the case shown in the figure, and feeds the cleaning water to the beginning of the pipe through a hose.

Then, washing water is jetted from the slit of the pipe.

The drying nozzle 5 uses a single closed-end pipe across the glass sheet A in the case shown in the figure, and supplies high-pressure air to the beginning of the pipe via a hose.

Then, air is injected from the slit of the pipe.

Further, on the downstream side of the drying nozzle 5, it sequentially moves from one end opposite to the running direction of the running sheet glass A to the other end (from the upper end to the lower end in FIG. 1), and moves forward and backward. A running drainer nozzle 6 for draining air is provided.

The advancing / retreating direction of the nozzle 6 is such that, in the case shown in the drawing, the injection surface of the nozzle 6 always coincides with the edge on the opposite side of the running direction of the glass sheet A, and is sequentially moved from the upper end to the lower end. A guide rail 7 that crosses the rail at an angle and a traveling body 8 to which the nozzle 6 is attached are supported.
And a belt 11 having both ends connected to the traveling body 8 and a driving reversible motor 12 for the sprocket 10 while rolling over a trochanter 9 embracing both side edges of the rail 7 and pulleys 10 provided at both ends of the rail 7. It is.

High pressure air is supplied from a hose (not shown) connected to the inlet 13 of the nozzle 6.

The transport of the plate glass A is not limited to the upright position shown in the figure, and the plate glass may be transported in a horizontal position.

With the above configuration, the cleaning surface is washed by spraying the washing water from the nozzle 4 onto the plate surface of the sheet glass A being transferred by the transfer device 1.

Next, high-pressure air is blown from the nozzles 5 onto the washed plate surface of the plate glass A being conveyed from the nozzle 5 to dry the plate surface while scattering attached moisture.

When the opposite side edge of the dry plate glass A in the running direction reaches the standby nozzle 6, the motor 12 drives the running body 8 in the forward direction.

Then, the nozzle 6 of the traveling body 8 is
Travels from one end to the other end of the opposite side of the running direction while always maintaining the matching of the nozzle 6 and the edge, and at the same time, high-pressure drainage air is jetted from the nozzle 6 so that the nozzle 6 wraps around the edge and adheres The remaining (remaining) washing water is scattered and draining is performed reliably.

When the nozzle 6 reaches the other end of the periphery, the traveling body 8 is returned to the original position by the reverse rotation operation of the motor 12, and is ready for the next draining.

In the illustrated case, the nozzles 4 and 5 are arranged on both plate sides of the sheet glass A. However, the nozzles are not limited to both sides, and the nozzles 4 and 5 may be arranged on one side.

Of course, the nozzle 6 also has a step on one side in the case of the sheet glass A shown in FIG.
Nozzles 6 on both sides of sheet glass A for draining the two-step surface on the edge
May be placed.

[0029]

According to the washing plate glass draining device according to the present invention, the washing water remaining on the opposite side edge of the plate glass in the running direction of the washing and drying can be reliably drained. Can eliminate various inconveniences.
