Assume that the loader configured in this manner is carried into a diaphragm chuck of a grinding machine, for example, with the reference surface of the chuck set at 20a and the chuck's claw set at 20b.
shall be. The loader arm 1, which inserts and grips the gear W into the cylindrical portion 13a of the workpiece gripping body 13, is positioned so that the gripper axis coincides with the chuck axis.
The gear W is inserted into the chuck where the loader arm 1 moves in the axial direction and the claw 20a is in an open state. Then, the loader arm 1 is at a position where the side surface of the gear W is in contact with the chuck reference surface 20a and the spring 6 is compressed and crimped.
stops moving. In this state, the solenoid valve 17
When switched to the position, pressurized air is supplied from the flow path 16 to the cylinder 2c, pushes the piston 10, and the piston shaft 8 further presses the gear W against the chuck reference surface 20a through the spherical hand. At this time, if the axis is not inclined, the end face of the flange 13b of the workpiece gripping body 13 and the end face of the sleeve 5 remain in close contact with each other, and almost no air is ejected from the nozzle 14. Therefore, the pressure switch 18 outputs a high pressure signal to confirm that the seating surface is normal.

If a workpiece is carried in and tilted after being chucked, a gap will be created between the end face of the flange 13b and the end face of the sleeve 5, regardless of the direction, and pressurized air will be ejected from the nozzle 14 and the air in the flow path 15 will be The pressure decreases, and the pressure switch 18 outputs a low pressure signal due to the decrease in pressure, thereby detecting that the workpiece is incorrectly seated. Therefore, the installation of the workpiece must be adjusted and reworked before starting machining.

Effects As detailed above, the present invention is provided with a gripper body that is capable of adjusting the axis perpendicular to the loader arm and has a cylinder on the axis so as to be able to slide a predetermined amount on the axis. The piston shaft is slidably inserted into the constantly energized sleeve, connected to the piston fitted in the cylinder, and the spherical hand at the tip receives the flanged workpiece grip, creating a gap between the sleeve surface and the sleeve surface due to the inclination of the flange surface. Since this is detected using an air nozzle, the seating state of the workpiece can be detected accurately and quickly during the loading operation of the loader, making loading more efficient and obtaining workpieces of normal and stable quality. It has the characteristics of being able to handle unmanned operations.
