Utilization of an air amplifier to remove sheets of paper from glass in an automated glass handler
View Patent ↗A method for removing a sheet of paper from a substrate includes providing an air exhaust stream from an outlet of an air amplifier to the sheet of paper on the substrate to perturb the sheet of paper and lifting the perturbed sheet of paper from the substrate using a sub-atmospheric intake of the air amplifier.
1. A method for removing a sheet of paper from a substrate, comprising:
providing an air exhaust stream from an outlet of an air amplifier to the sheet of paper on the substrate to perturb the sheet of paper;
lifting the perturbed sheet of paper from the substrate using a sub-atmospheric intake of the air amplifier; and
moving the air amplifier in relation to the sheet of paper on the substrate such that the air exhaust stream perturbs a first portion of the sheet of paper before the sub-atmospheric intake of the air amplifier passes over the first portion of the sheet of paper to lift the first portion of the sheet of paper from the substrate.
2. The method of claim 1 , wherein the sub-atmospheric intake generates a pressure below one atmosphere to lift the perturbed sheet of paper from the substrate.
3. The method of claim 2 , wherein the substrate comprises a glass plate.
4. The method of claim 3 , wherein the glass plate comprises a cover plate of a photovoltaic device.
5. The method of claim 4 , wherein the air amplifier moves in relation to the sheet of paper located on a stack of glass plates in which adjacent glass plates are separated by a respective sheet of paper.
6. The method of claim 1 , further comprising providing a high pressure air stream having a pressure above one atmosphere into a second inlet of the air amplifier, and directing the air exhaust stream in a direction that is 0 to 45 degrees from the horizontal direction to the sheet of paper.
7. The method of claim 1 , wherein the air amplifier is an impulse principle air amplifier or a Coanda effect air amplifier.
8. The method of claim 1 , wherein the air amplifier is suspended from at least one rail or a robot arm such that the air amplifier moves in the horizontal direction.
9. The method of claim 8 , further comprising a plurality of air amplifiers which move in tandem in the horizontal direction.
10. The method of claim 1 , wherein the air amplifier is suspended from at least one rail or a robot arm such that the air amplifier moves in the vertical direction.
11. The method of claim 10 , further comprising a plurality of air amplifiers which move in tandem in the vertical direction.
