Abstract
An expanding machine for expanding a sheet having a workpiece bonded on the sheet. The expanding machine includes an expansion mechanism configured to expand the sheet, a cooling unit that cools the workpiece bonded on the sheet, and a temperature distribution detection unit that, before expanding the sheet by the expansion mechanism, detects a temperature distribution of the workpiece cooled by the cooling unit. A method for expanding a sheet having a workpiece bonded on the sheet is also disclosed.
Claims9
An expanding machine for expanding a sheet having a workpiece bonded thereon, comprising:
- an expansion mechanism configured to expand the sheet;
- a cooling unit that cools the workpiece bonded on the sheet;
- and
- a temperature distribution detection unit that, before expanding the sheet by the expansion mechanism, detects a temperature distribution of the workpiece cooled by the cooling unit, and
- a controller that controls at least the expansion mechanism,
- wherein the controller has a determination section configured to determine whether the temperature distribution of the workpiece as detected by the temperature distribution detection unit is abnormal or normal,
- wherein a specified temperature is set within the controller, and when a temperature of the workpiece is higher than the specified temperature, the determination section determines the temperature distribution to be abnormal, and
- wherein expansion of the sheet is performed only when the temperature distribution detected is determined to be normal.
