  As shown in FIGS. 4A to 4C, the surface gripping step is a step of gripping the plate-like body S by moving the gripping portion 3 of the reversing device 1 shown in FIGS. . As shown in the initial state of FIG. 4A, the plate-like body S is placed on the pedestal T, and a predetermined process is applied to the surface side of the plate-like body S. At this time, the grip portion 3 of the reversing device 1 is retracted on both sides of the support column 2 so as not to contact the processing machine 7. Moreover, the stopper 35 of the grip part 3 is retracted to the back surface of the grip part 3 so as not to get in the way when the grip part 3 moves. First, one grip part 3 is moved to grip the surface of the plate S. Specifically, as shown in the movement state of FIG. 4B, the carriage 5 is moved on the rail 2r to move the grip portion 3 onto the plate-like body S, and the lifting device 6 is operated. The grip part 3 is moved down by operating the actuator 42 of the arm part 4 to rotate the grip part 3. With this process, the grip portion 3 can be moved onto the plate-like body S so that the grip portion 3 faces the surface of the plate-like body S.

FIG. 5B shows a state in which the upright plate-like body S is moved to a substantially central portion of the reversing device 1, but the carriage 5 is fixed at the position shown in FIG. Then, the plate-like body S may be in an upright state.

  As shown in FIG. 5C, the back surface gripping step is a step of holding the plate-like body S with the other gripping portion 3. As shown in the back surface gripping step in FIG. 5C, the other gripping portion 3 that has been retracted is moved, and the exposed back surface of the upright plate-like body S is gripped by the gripping portion 3. At this time, the carriage 5, the lifting device 6, and the actuator 42 of the arm portion 4 are controlled so that the grip portion 3 faces the back surface of the plate-like body S. And after arrange | positioning the other holding part 3 so as to oppose the back surface of the plate-shaped body S, the magnetic force is generated in the electromagnet 33, the plate-shaped body S is gripped, and the stopper 35 which was retracted is driven to drive the plate. The side surface portion and the surface of the shaped body S are supported. Then, the stopper 35 of the gripping part 3 that grips the surface of the plate-like body S is moved to the back of the gripping part 3 and retracted, the magnetic force of the electromagnet 33 is released, and the plate-like body S is detached from the gripping part 3. It can be so. By this processing, the back surface of the plate-like body S can be held and changed by the other gripping part 3, and the surface of the plate-like body S can be exposed.

  The previous placing step is a step of placing the changed plate-like body S on the pedestal T as shown in FIGS. As shown in the preparation state of FIG. 6A, the grip portion 3 that has gripped the surface of the plate-like body S is retracted by the carriage 5. Subsequently, as shown in the movement state of FIG. 6B, the carriage 5 is moved on the rail 2r to move the plate-like body S to a position where it does not contact the pedestal T, and the lifting device 6 is operated. The grip part 3 is moved down by operating the actuator 42 of the arm part 4 to rotate the grip part 3. 6C, the plate-like body S is lowered onto the pedestal T in a substantially horizontal state, and the stopper 35 is moved to the back surface of the grip portion 3 so as to be retracted. The magnetic force is released so that the plate-like body S can be detached from the grip portion 3. By such processing, the surface of the plate-like body S that has been subjected to the predetermined processing can be placed on the pedestal T with the surface thereof facing down.

  As shown in FIGS. 7A and 7B, the retracting process is a process of retracting the grip portion 3 that is the inverted plate-like body S. As shown in the movement state of FIG. 7A, the carriage 5 is moved on the rail 2r to move the plate-like body S to a position where it does not come into contact with the base T, and the lifting device 6 is operated to hold the gripping portion. 3 is raised to a position where it does not come into contact with the pedestal T, and the actuator 42 of the arm 4 is operated to rotate the grip 3. Finally, as shown in the retracted state of FIG. 7B, the grip portion 3 is moved to a position that does not interfere with the processing of the back surface of the plate S.

And inversion processing can be performed efficiently.

  Here, FIG. 8 is a diagram showing a modified example of the back surface gripping process, where (A) shows a back surface grip standby state, and (B) shows a back surface grip completion state. In this modified example, the plate-like body S is reduced by reducing the burden on the gripping section 3 in view of the fact that the standing state of the plate-like body S is likely to continue for a long time because the gripping section 3 waits for the approach or separation in the back surface gripping process. Is a process to make it difficult to fall.

  As shown in FIG. 8A, the grip portion 3 that grips the surface of the plate-like body S is tilted by an angle α with respect to the vertical axis so as to be rotated by 90 ° or more. A part of the weight of S is supported by the contact surface of the grip portion 3. The angle α is, for example, about 5 ° to 10 °. And it waits for the other holding part 3 holding the back surface of the plate-shaped body S to approach. FIG. 8A shows a state where the other gripping portion 3 has reached the back surface of the plate-like body S. In this state, a magnetic force is generated in the electromagnet 33 of the other gripping portion 3 to grip the plate-like body S, and the retracted stopper 35 is driven to support the side surface and the surface of the plate-like body S. Thereafter, both gripping portions 3 and 3 are rotated in the same direction by an angle 2α, so that the plate-like body S is tilted to the other gripping portion 3 side by an angle α with respect to the vertical axis. Then, the stopper 35 of the gripping part 3 that grips the surface of the plate-like body S is moved to the back of the gripping part 3 and retracted, the magnetic force of the electromagnet 33 is released, and the plate-like body S is detached from the gripping part 3. It can be so. This state is the back surface gripping completion state shown in FIG. With this process, a part of the weight of the plate-like body S can be supported by the contact surface of the gripping section 3 until the gripping section 3 that has grasped the surface of the plate-like body S is retracted. Here, the plate-like body S is tilted while holding the plate-like body S by both gripping portions 3, 3, but the plate-like body S is tilted while being held by either one of the gripping portions 3. You may make it make it.

On the other hand, the parts indicated by the solid lines of the parts A to D are parts that require chamfering and are parts cut by the processing machine 7. The surface cutting part chamfering process of FIG. 9B is a process of chamfering the cutting parts of the parts A to D. For example, a portion indicated by a broken line in FIG. 9B is chamfered. The reversing step in FIG. 9C is a step of reversing the front and back of the plate-like body S whose surface portion has been processed. For reversing the plate S, the reversing device 1 and the reversing method described above are used. FIG. 9C shows a state where the plate S is inverted. The back surface cutting part chamfering process of FIG.9 (D) is a process of chamfering the cutting part in each components AD of the plate-shaped object S inverted. For example, a portion indicated by a broken line in FIG. 9D is chamfered. By such a procedure, necessary processing can be efficiently performed on the front and back of the plate-like body S. In addition, as a chamfering method, there are a method of machining with a chamfering cutting tool attached to the processing machine 7, a method of melting an edge using a torch when the processing machine 7 is a plasma cutting machine, and the like. Though conceivable, it is not limited to these methods.

  Subsequently, a modified example of the grip portion 3 will be described. Here, FIGS. 10A and 10B are diagrams showing a modification of the gripper, where FIG. 10A is a first modification and FIG. 10B is a second modification.
