no. 1 approach
[0030] Such as figure 1 As shown, the end face processing device 1 according to the first embodiment includes: a motor 3 that drives and rotates a grinding wheel 2 as a processing tool; an arm member 4 that supports the grinding wheel 2 in a rotatable manner; a servo motor 5 that It acts as an actuator to generate a driving force for swinging the arm member 4 (for making the grinding wheel 2 press the end face E of the glass plate G); the link mechanism 6 transmits the driving force of the servo motor 5 to the arm member 4; The urging device 7 energizes the arm member 4 .
[0031] The motor 3 driving the grinding wheel 2 can use a synchronous motor, an induction motor, a servo motor, etc., but is not limited to these motors.
[0032] The arm member 4 is rotatably supported by a support shaft member 8 and is capable of swinging around the support shaft member 8 . The direction in which the arm member 4 swings includes both the direction in which the grindstone 2 separates fro...
no. 2 approach
[0053] Such as image 3 As shown, the end face processing device 1 according to the second embodiment differs from the end face processing device 1 according to the first embodiment in that the biasing device 7 includes a compression spring 7b instead of the tension spring 7a, and the compression spring 7b generates a force to The arm member 4 is biased in the direction in which the arm member 4 is swung by the driving force of the servo motor 5 .
[0054] In this embodiment, the compression spring 7b generates biasing|biasing so that the arm member 4 may be pressed in the direction which separates the grindstone 2 from the end surface E of the glass plate G. As shown in FIG.
no. 3 approach
[0056] Such as Figure 4 As shown, the end face processing device 1 related to the third embodiment is different from the end face processing devices 1 related to the first and second embodiments in that the force applying device 7 has a cylinder 7c instead of the springs 7a, 7b, and the cylinder 7c generates a biasing force in the direction in which the arm member 4 is swung by the driving force of the servo motor 5 .
[0057] In the present embodiment, the working cylinder 7c is configured to generate a force so as to pull the arm member 4 in a direction to separate the grinding wheel 2 from the end surface E of the glass plate G, but it may also be configured to move the grinding wheel 2 away from the glass plate G. A structure that generates force by pressing the arm member 4 in the direction of the end surface E of the arm. Using the hydraulic cylinder 7c in this way has an advantage that, compared with a spring, even if the swing angle changes due to the swing motion of...
