Abstract

A transfer system 1 comprising: a conveying/positioning device 3 configured to convey and position a flat sheet-shaped mold MA in a predetermined direction, on which a fine transfer pattern M 1 is formed; a transfer device 5 configured to transfer the fine transfer pattern M 1 to a molding target W, the transfer device 5 being provided on an upstream side in the conveying direction of the sheet-shaped mold MA; and a peeling device 7 configured to peel off the sheet-shaped mold MA and the molding target from those mutually clinging to each other, after the transfer by the transfer device 5 is performed and the conveyance by the conveying/positioning device 3 is performed, the peeling device 7 being provided on a downstream side in the conveying direction of the sheet-shaped mold MA.

First claim

The invention claimed is:

1. A transfer system comprising:
a conveying/positioning device configured to convey and position a flat sheet-shaped mold in a predetermined direction, on which a fine transfer pattern is formed;
a transfer device configured to transfer the fine transfer pattern to a molding target, the transfer device being provided at a position in the conveying direction of the conveying/positioning device, the transfer device comprising a press body and a molding target placing body configured to place the molding target thereon, the transfer device being configured to sandwich the molding target and the flat sheet-shaped mold between the press body and the molding target placing body to perform the transfer, the press body comprising:
a base material comprising a highly rigid material;
shock-absorbing material provided in a layer covering the base material and configured to sandwich the molding target and the flat sheet-shaped mold between the press body and the molding target placing body; and
a mold contact material provided in a layer covering the shock-absorbing material; and

a peeling device configured to peel off the sheet-shaped mold and the molding target from those mutually clinging to each other, after the transfer by the transfer device is performed and the conveyance by the conveying/positioning device is performed, the peeling device being provided on a downstream side from the transfer device in the conveying direction of the conveying/positioning device,
wherein the conveying/positioning device stops conveyance of the flat sheet-shaped mold when the transfer device performs the transfer or the peeling device performs the peeling.

2. The transfer system according to claim 1 , further comprising:
a sheet-shaped mold production device configured to form a fine transfer pattern on a sheet-shaped raw material to produce the sheet-shaped mold,
wherein, a plurality of unit sets are provided with respect to the one sheet-shaped mold production device, and each unit set includes the one conveying/positioning device, the one transfer device and the one peeling device.

3. The transfer system according to claim 1 ,
wherein the flat sheet-shaped mold is a sheet-shaped mold pulled out from a rolled mold in which the sheet-shaped mold is wound, and
the fine transfer pattern is formed on a transfer pattern forming area as a part of the sheet-shaped mold, and a laminate film is provided on a region of the sheet-shaped mold, the region being other than the transfer pattern forming area.

4. A transfer method to the molding target,
wherein the transfer method is performed by using the transfer system according to claim 1 .

5. A transfer method to the molding target,
wherein the transfer method is performed by using the transfer system according to claim 2 .

6. A transfer method to the molding target,
wherein the transfer method is performed by using the transfer system according to claim 3 .

7. The transfer system according to claim 2 ,
wherein the flat sheet-shaped mold is a sheet-shaped mold pulled out from a rolled mold in which the sheet-shaped mold is wound, and
the fine transfer pattern is formed on a transfer pattern forming area as a part of the sheet-shaped mold, and a laminate film is provided on a region of the sheet-shaped mold, the region being other than the transfer pattern forming area.

8. A transfer system comprising:
a flat sheet-shaped mold on which a fine transfer pattern is formed;
a conveying/positioning device configured to convey and position the flat sheet-shaped mold in a predetermined direction;
a transfer device configured to transfer the fine transfer pattern to a molding target, the transfer device being provided at a position in the conveying direction of the conveying/positioning device; and
a peeling device configured to peel off the sheet-shaped mold and the molding target from those mutually clinging to each other, after the transfer by the transfer device is performed and the conveyance by the conveying/positioning device is performed, the peeling device being provided on a downstream side from the transfer device in the conveying direction of the conveying/positioning device,
wherein the conveying/positioning device stops conveyance of the flat sheet-shaped mold when the transfer device performs the transfer or the peeling device performs the peeling.

9. A transfer method to the molding target,
wherein the transfer method is performed by using the transfer system according to claim 8 .

10. The transfer system according to claim 8 , further comprising:
a sheet-shaped mold production device configured to form a fine transfer pattern on a sheet-shaped raw material to produce the sheet-shaped mold,
wherein, a plurality of unit sets are provided with respect to the one sheet-shaped mold production device, and each unit set includes the one conveying/positioning device, the one transfer device and the one peeling device.

11. The transfer system according to claim 8 ,
wherein the transfer device comprises a press body and a molding target placing body configured to place the molding target thereon,
the transfer device is configured to sandwich the molding target and the flat sheet-shaped mold by the press body and the molding target placing body to perform the transfer, and
the press body is configured to perform the sandwiching by a shock-absorbing material.

12. A transfer method to the molding target,
wherein the transfer method is performed by using the transfer system according to claim 10 .

13. The transfer system according to claim 11 ,
wherein the press body includes: a base material composed of a highly rigid material; the shock-absorbing material provided in a layer shape so as to cover the base material; and a mold contact material provided in a layer shape so as to cover the shock-absorbing material.

14. The transfer system according to claim 8 ,
wherein the flat sheet-shaped mold is a sheet-shaped mold pulled out from a rolled mold in which the sheet-shaped mold is wound, and
the fine transfer pattern is formed on a transfer pattern forming area as a part of the sheet-shaped mold, and a laminate film is provided on a region of the sheet-shaped mold, the region being other than the transfer pattern forming area.

15. The transfer system according to claim 10 ,
wherein the transfer device comprises a press body and a molding target placing body configured to place the molding target thereon,
the transfer device is configured to sandwich the molding target and the flat sheet-shaped mold by the press body and the molding target placing body to perform the transfer, and
