Glass washing machine with broken glass removal system
View Patent ↗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.
1. A glass sheet washing machine, comprising:
a) a support for a glass sheet being washed;
b) a liquid container positioned below said support;
c) a pump coupled to said liquid container;
d) a liquid applicator coupled to said pump for applying a liquid from said liquid container to wash said glass sheet, wherein an excess of said liquid falls into said liquid container; and
e) a moveable web positioned between said support and said liquid container to catch pieces of a broken glass sheet to inhibit said pieces from entering said liquid container and remove the pieces from the glass washing machine.
2. The machine of claim 1 wherein said web is liquid permeable.
3. The glass washing machine of claim 1 wherein said web is supported by first and second rotatable rolls, rotation of said rolls moves said web to remove said broken pieces of glass from a region below said applicator.
4. The glass washing machine of claim 1 wherein a first end of said web is connected to a first rotatable roll and a second end of said web is connected to a second rotatable roll, rotation of said rolls moves said web to remove said broken pieces of glass from a region below said applicator.
5. The glass washing machine of claim 1 wherein said web is belt disposed around first and second rotatable rolls, rotation of said rolls moves said web to remove said broken pieces of glass from a region below said applicator.
6. The glass washing machine of claim 1 further comprising a trough disposed below said web for receiving said broken pieces of glass.
7. The glass washing machine of claim 1 wherein said web is a perforated belt.
8. The glass washing machine of claim 1 wherein said web is a wire mesh belt.
9. The glass washing machine of claim 1 further comprising a float moveably positioned within said liquid container, the float regulating the liquid level in said liquid container by opening an liquid inlet for the flow of fluid into said liquid container when said float moves to a first position below a threshold and said float stopping the flow of fluid through said inlet when said float moves to a second position above said threshold.
10. The glass washing machine of claim 1 wherein said moveable web extends to an outward position of the glass washing machine such that said moveable web covers an entire opening of the liquid container.
11. A glass sheet washing machine, comprising:
a) a support for a glass sheet being washed;
b) a liquid container positioned below said support;
c) a liquid applicator coupled to a pump for applying a liquid to wash said glass sheet, wherein an excess of said liquid falls into said liquid container; and
d) a moveable web positioned between said support and said liquid container to catch pieces of a broken glass sheet to inhibit said pieces from entering said liquid container and remove the pieces from the glass washing machine.
12. A glass sheet washing machine, comprising:
a washing station and a rinsing station for washing and rinsing, respectively glass sheets as the glass sheets pass through the glass sheet washing machine, the washing and rinsing stations each separately comprising:
a support for the glass sheets being washed;
a liquid container positioned below said support;
a pump for supplying liquid to the glass sheets during washing or rinsing in the respective station; and
a liquid applicator coupled to said pump for applying a liquid from a liquid supply to wash or rinse said glass sheet, wherein an excess of said liquid falls into said liquid container;
the glass sheet washing machine further comprising a moveable web positioned to pass through said washing station and said rinsing station at a location between said support and said liquid container of the washing and rinsing stations such that said moveable web catches pieces of a broken glass sheet and inhibits said pieces from entering said liquid containers and remove the pieces from the glass sheet washing machine.
13. The glass sheet washing machine of claim 12 wherein said liquid supply for said washing station is said liquid container of said rinsing station.
14. The glass sheet washing machine of claim 12 wherein said web is liquid permeable.
15. The glass sheet washing machine of claim 12 wherein said web is supported by first and second rotatable rolls, rotation of said rolls moves said web to remove said broken pieces of glass from a region below said applicator.
16. The glass sheet washing machine of claim 12 wherein a first end of said web is connected to a first rotatable roll and a second end of said web is connected to a second rotatable roll, rotation of said rolls moves said web to remove said broken pieces of glass from a region below said applicator.
17. The glass sheet washing machine of claim 12 wherein said web is belt disposed around first and second rotatable rolls, rotation of said rolls moves said web to remove said broken pieces of glass from a region below said applicator.
18. The glass sheet washing machine of claim 12 further comprising a trough disposed below said web for receiving said broken pieces of glass.
19. The glass sheet washing machine of claim 12 wherein said web is a perforated belt.
20. The glass sheet washing machine of claim 12 further comprising a pre-wash station and a final rinse station, the pre-wash and final rinse stations comprising:
a support for the glass sheets being washed;
a liquid container positioned below said support;
a pump for supplying liquid to the glass sheets during washing or rinsing in the respective station; and
a liquid applicator coupled to said pump for applying a liquid from a liquid supply to wash or rinse said glass sheet, wherein an excess of said liquid falls into said liquid container;
wherein said moveable web is positioned to pass through said pre-wash, washing, rinsing, and final washing stations at a location between said support and said liquid container of the pre-wash, washing, rinsing, and final washing stations such that said moveable web catches pieces of a broken glass sheet and inhibits said pieces from entering said liquid containers and remove the pieces from the glass sheet washing machine.
