Sheet-laminating device and sheet-laminating method

A sheet-laminating device comprising:

• a first conveyance handler which can move between a standby position located above a stage and a retracted position retracted from the standby position, and can move vertically to the stage, and is capable of holding a sheet with at least a portion of a periphery thereof protruding;
• a first clamping device movable between a first pressing position where a first side of the sheet laminate on the stage is pressed toward the stage, and a first upper position that is above the first pressing position, and is adjacent to the standby position;
• a second clamping device movable between a second pressing position where a second side different from the first side of the sheet laminate on the stage is pressed toward the stage and a second upper position that is above the second pressing position, and is adjacent to the standby position;
• and
• a control unit causing:
• the first clamping device to move to the first upper position while the second side of the sheet laminate on the stage is being pressed with the second clamping device;
• the first conveyance handler, which is holding a first sheet, to move to the standby position above the stage from the direction opposite to the first clamping device with the stage therebetween;
• the first conveyance handler to be descended toward the stage to laminate the first sheet on the sheet laminate, which is being pressed by the second clamping device;
• and the first clamping device to be descended toward the stage to press the periphery of the first sheet, which is protruding from the first conveyance handler, toward the stage.

A sheet-laminating method using a sheet conveying device which comprises:

• a first conveyance handler which can move between a standby position located above the stage and a retracted position retracted from the standby position, and can move vertically to the stage, and is capable of holding a sheet with at least a portion of a periphery thereof protruding;
• a first clamping device movable between a first pressing position where a first side of the sheet laminate on the stage is pressed toward the stage, and a first upper position that is above the first pressing position, and is adjacent to the standby position;
• and a second clamping device movable between a second pressing position where a second side different from the first side of the sheet laminate on the stage is pressed toward the stage and a second upper position that is above the second pressing position, and is adjacent to the standby position, the method comprising:
• moving the first clamping device to the first upper position while the second side of the sheet laminate on the stage is being pressed with the second clamping device;
• moving the first conveyance handler, which is holding a first sheet, to the standby position above the stage from the direction opposite to the first clamping device with the stage therebetween;
• descending the first conveyance handler toward the stage, and laminating the first sheet on the sheet laminate, which is being pressed by the second clamping device;
• and
• descending the first clamping device toward the stage, and pressing the periphery of the first sheet, which is protruding from the first conveyance handler, toward the stage.
