Method and apparatus for locating and conveying sheet-like body

A method for locating and conveying a sheet-like body, comprising the steps of:

• causing a downstream side end portion of a sheet-like body supported only at an underside thereof and conveyed by a travelling conveying member to abut against a blocking member to correct the attitude of the sheet-like body in such a state that the downstream side end portion of the sheet-like member is perpendicular to the conveying direction of the sheet-like body;
• moving the blocking member to a position where the blocking member does not abut against the sheet-like body;
• and
• moving the conveying member in the direction perpendicular to the conveying direction until one side end of the sheet-like body in the direction perpendicular to the conveying direction reaches a predetermined position.

An apparatus for locating and conveying a sheet-like body, comprising:

• a conveying member which supports a sheet-like body only at an underside thereof and conveys the same in a conveying direction by travelling thereof and which can reciprocate in an X direction perpendicular to the conveying direction;
• a moving mechanism which reciprocates the conveying member in the X direction;
• a blocking member which can reciprocate between a position where the blocking member abuts against the sheet-like body conveyed in the conveying direction by the conveying member to block conveyance of the sheet-like body and a position where the blocking member allows passing of the sheet-like body;
• a first detector which detects whether or not the downstream side end of the sheet-like body is positioned to abut against the blocking member which stands by at a position where the blocking member prevents the conveyance;
• a second detector which detects that one side end of the sheet-like body in the direction perpendicular to the conveying direction of the sheet-like body has reached the predetermined position by movement of the conveying member in the X direction effected by actuation of the moving mechanism;
• a controller which performs such control that both of moving the blocking member at the position where the blocking member allows passing of the sheet-like body and actuating the moving mechanism to move the conveying member in the X direction are simultaneously performed or either one thereof is first performed on the basis of a signal form the first detector which has detected the downward side end of the sheet-like body conveyed by the conveying member in the state where the blocking member stands by at the position where the blocking member prevents the conveyance, and
• the moving mechanism is then stopped on the basis of a signal from the second detector which has detected the sheet-like body.
