摘要： An angle detection method for a bending machines for detecting a bending angle of a bent workpiece and an angle detection apparatus and an angle sensor thereof are provided.
A detection light is emitted toward a workpiece W from a light source 9 while the angle sensor 3 is rotated in the forward and reverse directions. A plurality of optical sensors 11, 13 arranged at mutually symmetrical positions with the light source 9 being at the center thereof receive the reflection light from the measurement object W. The quantity of received light is stored in relation to the rotation angle of the angle sensor 3 detected by an rotation angle detector 33. A angle calculation portion 35 calculates the angle of the measurement object W based on the peak values of the data of the quantity of the received light and the rotation angles of the angle sensor 3 corresponding to the peak values. Alternatively, the rotation angle detector 3 detects the rotation angles of the angle sensor 3 at the time when the quantities of the received light received by the pair of optical sensors 11, 13 are the same, and the angle calculation portion 33 calculates the angle of the measurement object W based on the rotation angles.

摘要： In order to load and discharge pieces of sheet metal automatically onto and from a machine tool (20) having a horizontal table (26) movable along a first horizontal axis (X), a horizontal discharge table (52) and a horizontal loading table (58) are provided in positions in which the tables are side by side and substantially aligned with the horizontal plane of the table (26) of the machine tool (20). An unprocessed piece of sheet metal to be supplied to the machine tool (20) is placed on the loading table (58). Initially, the piece-holding table (26) of the machine tool (20) is positioned beside the discharge table (52). The piece of sheet metal (30) on the piece-holding table (26) is transferred to the discharge table (52) by being slid on the bearing surfaces of the tables in the direction of a second horizontal axis (Y) perpendicular to the first axis (X). The table (26) of the machine tool (20) is then moved to a position in which it is beside the loading table (58). The unprocessed piece of sheet metal situated on the loading table (58) is then transferred to the piece-holding table (26) by being slid on the bearing surfaces of these tables.
