Abstract

A glass sheet washing machine with a broken glass removal system includes a support, a liquid container or reservoir, a pump, a liquid applicator, and a liquid permeable member. The support supports a glass sheet being washed. The liquid reservoir is positioned below the support. The pump is coupled to the liquid reservoir. The liquid applicator is coupled to the pump. The liquid applicator applies the liquid from the liquid reservoir to wash the glass sheet. Excess liquid falls into the reservoir. The liquid permeable member is positioned between the support and the liquid reservoir to catch pieces of glass to inhibit the pieces of broken glass from falling into the liquid reservoir and is moved to remove the pieces from the glass washing machine.

Claims

1. A method of removing pieces of a broken glass sheet from a glass sheet washing machine, comprising:

a) applying a fluid to a rotating brush;

b) moving a glass sheet into contact with said rotating brush to wash said glass sheet;

c) placing a fluid permeable belt between said rotating brush and a fluid container of said glass washing machine;

d) communicating excess fluid applied to said brush through said fluid permeable belt to said container;

e) catching pieces of a broken glass sheet with said fluid permeable belt to inhibit said pieces from entering said fluid container;

f) moving by a controlled condition said fluid permeable belt to remove said broken glass pieces from said glass washing machine, the controlled condition comprising;

i) monitoring the glass sheet for breaks during the movement of the glass sheet through the glass sheet washing machine; and

ii) activating the motion of said liquid permeable belt for a prescribed period of time upon detecting a break in the glass sheet during the monitoring operation, the activating the motion of the liquid permeable belt for said prescribed period of time facilitates the removal of the broken glass from the surface of said liquid permeable belt.

2. The method of claim 1 wherein said liquid permeable belt is supported by first and second rotatable rolls, said rolls are rotated to move said liquid permeable belt to remove said broken pieces of glass from said glass washing machine.

3. The method of claim 1 wherein a first end of said liquid permeable belt is connected to a first rotatable roll and a second end of said liquid permeable belt is connected to a second rotatable roll, said rolls are rotated to move said liquid permeable belt and remove said broken pieces of glass from said glass washing machine.

4. The method of claim 1 wherein said liquid permeable belt is disposed around first and second rotatable rolls, said rolls are rotated to move said liquid permeable belt and remove said broken pieces of glass from said glass washing machine.

5. The method of claim 1 further comprising moving said liquid permeable belt to remove said broken pieces of glass and drop said broken pieces of glass into a trough disposed below said liquid permeable belt.

6. The method of claim 1 wherein the step of said moving said liquid permeable belt to remove said broken pieces of glass is achieved by coupling a mechanical assist to said liquid permeable belt.

7. The method of claim 6 wherein mechanical assist is a manual crank.

8. The method of claim 6 wherein the mechanical assist is a motor.

9. The method of claim 8 wherein the liquid permeable belt is continuously looped around first and second rotatable rolls.

10. The method of claim 8 further comprising moving said liquid permeable belt to remove said broken glass occurs only as a result of selectively enabling said motor.

11. A method of removing pieces of a broken glass sheet from a glass sheet washing machine, comprising:

a) applying a fluid to a rotating brush;

b) moving a glass sheet into contact with said rotating brush to wash said glass sheet;

c) placing a fluid permeable belt between said rotating brush and a fluid container of said glass washing machine;

d) communicating excess fluid applied to said brush through said belt to said container;

e) catching pieces of a broken glass sheet with said liquid permeable belt to inhibit said pieces from entering said fluid container;

f) moving said belt to remove said broken glass pieces from said glass washing machine; and

g) providing first and second rotatable rolls that support said liquid permeable belt, said first and second rolls are rotated to move said liquid permeable belt to remove said broken pieces of glass from said glass washing machine, wherein said liquid permeable belt comprises a first end connected to said first rotatable roll and a second end connected to said second rotatable roll, the length of the liquid permeable belt between said first and second ends being longer than the distance between the first rotatable roll and the second rotatable roll and the extra length of said liquid permeable belt can be rolled onto said first or second rotatable roll to remove the broken glass from said glass washing machine.

12. The method of claim 11 further comprising the step of extending said first and second rotatable rolls such that said fluid permeable belt covers an outer perimeter of said fluid container.

13. The method of claim 12 further comprising the step of sensing the occurrence of a breaking of a glass sheet with a sensor.

14. The method of claim 13 wherein the step of moving the liquid permeable belt to remove said broken pieces of glass occurs as a result of said sensing the occurrence of a breaking of a glass sheet with said sensor.

15. The method of claim 11 wherein the step of said moving said liquid permeable belt to remove said broken pieces of glass is achieved by coupling a mechanical assist to said liquid permeable belt.

16. The method of claim 15 wherein the mechanical assist is a motor.

17. A method of removing pieces of a broken glass sheet from a glass sheet washing machine, comprising:

a) applying a fluid to a rotating brush;

b) moving a glass sheet into contact with said rotating brush to wash said glass sheet;

c) placing a fluid permeable belt between said rotating brush and a fluid container of said glass washing machine;

d) communicating excess fluid applied to said brush through said belt to said container;

e) catching pieces of a broken glass sheet with said liquid permeable belt to inhibit said pieces from entering said fluid container;

f) moving said belt to remove said broken glass pieces from said glass washing machine; and

g) sensing an occurrence of a breaking of a glass sheet with a sensor such that said moving said belt to remove said broken glass pieces from said glass washing machine occurs only upon said sensing the occurrence of a breaking of a glass sheet.

18. The method of claim 17 wherein said moving said belt occurs for a prescribed period of time once said sensing an occurrence of a breaking of a glass sheet with a sensor is sensed, the prescribed period of time facilitates the removal of the broken glass from the surface of said belt.

19. The method of claim 18 wherein a first end of said liquid permeable belt is connected to a first rotatable roll and a second end of said liquid permeable belt is connected to a second rotatable roll, said rolls are rotated to move said liquid permeable belt and remove said broken pieces of glass from said glass washing machine.

20. The method of claim 17 wherein a first end of said liquid permeable belt is connected to a first rotatable roll and a second end of said liquid permeable belt is connected to a second rotatable roll, said rolls are rotated to move said liquid permeable belt and remove said broken pieces of glass from said glass washing machine.
