Abstract

A sheet transfer apparatus and a method for transferring a sheet using a sheet transfer apparatus are provided. A sheet transfer apparatus includes: a table on which two or more sheets, which are continuously laminated, are configured to be seated; a sheet adsorbing part on the table to adsorb a first sheet, which is at an uppermost portion, of the two or more laminated sheets at a pressure; and an air discharge part on the table and adjacent to the sheet adsorbing part, and the air discharge part is configured to discharge air to a surface of the first sheet adsorbed to the sheet adsorbing part.

First claim

What is claimed is:

1. A sheet transfer apparatus comprising:
a table on which two or more sheets, which are laminated, are configured to be seated;
a sheet adsorbing part over the table to adsorb a first sheet, which is at an uppermost portion, of the two or more laminated sheets at a pressure;
an air discharge part over the table and adjacent to the sheet adsorbing part; and
an elevation unit configured to elevate the sheet adsorbing part and the air discharge part,
wherein the elevation unit comprises:
a support part; and
an elevation part configured to elevate the support part,
wherein the air discharge part is configured to discharge air in a downward direction onto a surface of the first sheet adsorbed to the sheet adsorbing part.

2. The sheet transfer apparatus of claim 1 , wherein the support part comprises a long side extending in a first direction and a short side extending in a second direction crossing the first direction.

3. The sheet transfer apparatus of claim 2 , wherein the sheet adsorbing part comprises a first sheet adsorbing part and a second sheet adsorbing part, which are connected to the support part, spaced apart from each other in the first direction, and respectively arranged on outer portions of the support part in the long side first direction.

4. The sheet transfer apparatus of claim 3 ,
wherein the air discharge part comprises:
first and second air discharge parts arranged in parallel with the first sheet adsorbing part therebetween in the second direction; and
third and fourth air discharge parts arranged in parallel with the second sheet adsorbing part therebetween in the second direction.

5. The sheet transfer apparatus of claim 1 , wherein a metal sheet is configured to be further seated on the table, and
the metal sheet on the table, the second sheet on the metal sheet, and the first sheet on the second sheet are sequentially laminated.

6. The sheet transfer apparatus of claim 5 , further comprising a metal sheet adsorbing part configured to adsorb the metal sheet and disposed on an inner portion of the support part in a long side direction.

7. The sheet transfer apparatus of claim 6 , wherein the metal sheet adsorbing part comprises a first metal sheet adsorbing part and a second metal sheet adsorbing part, which are spaced apart from each other.

8. The sheet transfer apparatus of claim 7 , further comprising an auxiliary air discharge part adjacent to the metal sheet adsorbing part,
wherein the auxiliary air discharge part comprises:
fifth and sixth air discharge parts arranged in parallel with the first metal sheet adsorbing part therebetween in a second direction; and
seventh and eighth air discharge parts arranged in parallel with the second metal sheet adsorbing part therebetween in the second direction.

9. The sheet transfer apparatus of claim 6 , wherein the sheet adsorbing part and the metal sheet adsorbing part are spaced from each other by a distance of about 25 cm to about 30 cm.

10. The sheet transfer apparatus of claim 1 , wherein the sheet adsorbing part and the air discharge part are spaced from each other by a distance of about 40 mm to about 60 mm.
