In general, plate glass is cut into the application and is made of tempered glass by the reinforcing process for safety in use.

Such a tempered glass plate is produced by the washing step, drying step, marking step, the heat treatment step by the heating furnace, quenching step while producing a tempered glass 4 to 6 times more resistant to impact than ordinary glass.

At this time, due to the concentration of stress on the sharp edges cut during the heat treatment of the plate glass, to prevent damage to the plate glass, such as cracking or breakage of the plate glass as a pre-treatment, the edges of the sharp four sides by rotating the processing wheel of the diamond material is chamfered.

The use of the apparatus for processing the edges of the panes used in the reinforcement pretreatment of the panes is already well known in the art.

The processing apparatus of the conventional plate glass edge is called the linear chamfering machine, and several head apparatus is applied.

The head device is provided with a rotary machining head and a straight machining head that moves straight along the guide rail, each of which moves while rotating a machining wheel of a diamond material assembled to a driving motor, thereby connecting the end face of the plate glass, which is a rotational workpiece, to a seam.

Move the rotary machining head 100 from the left to the right with respect to the conveying direction of the plate glass (P / G) while completing the chamfering of the corners, and return to the original position by the control of the pneumatic cylinder 260 to move the motor Return 130 and at the same time, the straight processing head 110 is also reversed and returned to its original position, and at the same time, the movable motor 130 is also moved backward by the control of the pneumatic cylinder 260 (see FIGS. 32 and 33).

After the chamfering is completed, the plate glass (P / G) is transferred by the conveyer 10 after processing, and at the same time, the plate glass (P / G) to be newly processed is conveyed by the conveyer 10 before the transfer and the rotary head is processed. 100 is rotated 90 degrees (see Fig. 34), the plate glass (P / G) to be processed continues to advance to the plate glass (P / G) on the guide bar 230 of the rotary processing head 100 as shown in FIG. Positioning the front side of the) and repeating the process of Fig. 21 to 34 is provided chamfering of the four sides of the pane (P / G).

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below but also by the equivalents of the claims.

100: rotary machining head 110: weaving
200: height adjustment buffer means 250: processing close contact means
