Abstract

Provided is a glass winding system configured to switch between a breaking mode and a winding mode in which glass is wound with an interleaf to form the glass roll. Furthermore, a system for forming glass rolls includes a glass ribbon supply system (100), a cutting system (200) configured to cut the initial glass ribbon into a first glass ribbon and a second glass ribbon, a first glass winding system (400) configured to wind the first glass ribbon to form a first glass roll, and a second glass winding system (300) configured to switch between a breaking mode and a winding mode.

First claim

1 . A glass winding system comprising:
a glass winder configured to wind glass with an interleaf to form a glass roll; an interleaf unwinder configured to unwind the interleaf from an interleaf roll; and a breaking unit configured to break the glass, wherein the glass winding system is configured to switch between a breaking mode in which the glass is broken and a winding mode in which the glass is wound with the interleaf to form the glass roll.

2 . The glass winding system of claim 1 , wherein the breaking unit is further configured to rotate with respect to a rotation axis to allow the glass winding system to switch between the breaking mode and the winding mode.

3 . The glass winding system of claim 1 , further comprising a first roller used at a first position in the winding mode,
wherein the first roller is removed from the first position in the breaking mode.

4 . The glass winding system of claim 1 , further comprising:
a second roller used at a second position in the winding mode, wherein the second roller is removed from the second position in the breaking mode; and a roller holder configured to hold the second roller in the breaking mode.

5 . The glass winding system of claim 1 , being arranged on a floor, wherein the glass winder is arranged between the floor and the interleaf unwinder.

6 . The glass winding system of claim 1 , wherein the glass winder is configured to switch between a clockwise mode in which the glass is wound clockwise with the interleaf and a counterclockwise mode in which the glass is wound counterclockwise with the interleaf.

7 . The glass winding system of claim 6 , further comprising:
a third roller used in the clockwise mode and not used in the counterclockwise mode; and a fourth roller used in the counterclockwise mode and not used in the clockwise mode.

8 . The glass winding system of claim 1 , further comprising:
a first diameter sensor configured to measure a diameter of the glass roll; and a first sensor moving unit configured to move the first diameter sensor in a direction parallel to a rotation axis of the glass roll.

9 . The glass winding system of claim 8 , being configured to control a tension of the glass according to the diameter of the glass roll.

10 . The glass winding system of claim 1 , further comprising a load cell roller configured to sense a tension of the glass.

11 . The glass winding system of claim 1 , further comprising a dancer roller configured to control a tension of the glass.

12 . The glass winding system of claim 1 , further comprising:
a second diameter sensor configured to measure a diameter of the interleaf roll; and a second sensor moving unit configured to move the second diameter sensor in a direction parallel to a rotation axis of the interleaf roll.

13 . The glass winding system of claim 1 , further comprising:
a position sensor configured to sense a position of the glass in a direction parallel to a rotation axis of the glass roll; and a moving device configured to move the glass winder according to a position of the glass.

14 . A system for forming glass rolls, the system comprising:
a glass ribbon supply system configured to supply an initial glass ribbon; a cutting system configured to cut the initial glass ribbon into a first glass ribbon and a second glass ribbon; a first glass winding system configured to wind the first glass ribbon to form a first glass roll; and a second glass winding system configured to switch between a breaking mode in which the second glass ribbon is broken and a winding mode in which the second glass ribbon is wound to form a second glass roll.

15 . The system of claim 14 , wherein the glass ribbon supply system comprises a glass unwinder configured to unwind the initial glass ribbon from an initial glass roll.

16 . The system of claim 14 , wherein the second glass winding system comprises:
a glass winder configured to wind the second glass ribbon to form the second glass roll; and a breaking unit configured to break the second glass ribbon, wherein the breaking unit is rotatable with respect to a rotation axis to allow the second glass winding system to switch between the breaking mode and the winding mode.

17 . The system of claim 16 , wherein the second glass winding system further comprises a first roller used at a first position in the winding mode, and
the first roller is removed from the first position in the breaking mode.

18 . The system of claim 16 , wherein the second glass winding system further comprises:
a second roller used at a second position in the winding mode, the second roller is removed from the second position in the breaking mode; and a roller holder configured to hold the second roller in the breaking mode.

19 . The system of claim 16 , wherein the second glass winding system further comprises an interleaf unwinder configured to unwind an interleaf from an interleaf roll,
the second glass winding system is arranged on a floor, and the glass winder is arranged between the floor and the interleaf unwinder.

20 . The system of claim 16 , wherein the glass winder is configured to switch between a clockwise mode in which the second glass ribbon is wound clockwise and a counterclockwise mode in which the second glass ribbon is wound counterclockwise.
