4th embodiment
Fig. 8 and 9 illustrate that NC controls cutting equipment 60, and it is also the glass plate streaking device for implementing fourth embodiment of the invention that this NC controls cutting equipment 60。
In this glass plate cutting equipment 60, the load seat 62 being provided with cutting wheel 61 is subject to NC control and moves in plane coordinate system。Thus, cutting wheel 61 is subject to NC control and moves in orthogonal coordinate system。
As shown in Figure 8, pair of guide rails 64 is arranged on base portion 63 along X-axis line, and motion base 65 is moved along X-direction by guide rail 64。Additionally, the pair of guide rails 66 along Y-axis extension is arranged on this motion base 65。Above-mentioned load seat 62 can be moved along Y direction by these guide rails 66。Motion base 65 controls motor 67 and pinion rack device or feed screw by X-axis and lower moves along X-direction digital control。
Load seat 62 on motion base 65 controls motor 68 and pinion rack device or feed screw by Y-axis and lower moves along Y direction digital control。
Thus, the position of load seat 62 is controlled along X-direction and Y direction, and the cutting wheel 61 being arranged on load seat 62 moves along pre-programmed movement locus。As it is shown in figure 9, the cutting head 69 also serving as cut head is arranged on the front surface of load seat 62。
Cutting head 69 includes: splined shaft 71, and this splined shaft 71 has cutting wheel keeper 70 at its lower end；Rotating spline unit 72, this rotation spline unit 72 is for being maintained at center by this splined shaft 71 so that splined shaft 71 can vertically move and also rotatable；And piston-cylinder unit 74, this piston-cylinder unit 74 is connected to the upper end of splined shaft 71 by freely rotatable joint 73。The main body of piston-cylinder unit 74 is arranged on load seat 62 certainly, and the freely rotatable joint 73 of piston rod 75 above is connected to splined shaft 71。
Cutting wheel 61 is arranged in above-mentioned cutting wheel keeper 70。The axis of cutting wheel 61 arranges (relative to direct of travel backward) relative to the eccentric axis of splined shaft 71 certainly。
It is maintained at the splined shaft 71 rotated in spline unit 72 to be vertically moved along Z-direction (being perpendicular to the surface of glass plate 2) in rotation spline unit 72 by piston-cylinder unit 74。
Additionally, during cut, cutting wheel 61 is applied air pressure by the orthogonal direction along glass plate 2 surface。Additionally, splined shaft 71 is driven rotationally by rotating spline unit 72。Angle ambiguity motor 76 is arranged on the side rotating spline unit 72。
Rotate spline unit 72 and there is the driving gear 77 for making splined shaft 71 rotate。When this driving gear 77 engages cooperation with the gear 78 being arranged on Angle ambiguity motor 76, splined shaft 71 and therefore cutting wheel 61 rotate under the Angle ambiguity of this Angle ambiguity motor 76。
That is, the cutting edge surface of cutting wheel 61 is subject to Angle ambiguity with towards cut direction。Glass plate 2 is placed on the tables 79 being arranged on base portion 63, and is held on request and fix。
Hereafter, this streaking device 1 will be given by implement the description of cut method of the present invention。
Every time beginning through scroll-diced wheel 61 while to cutting wheel 61 applying air pressure and before operation that cut forms score line at once, first cutting is taken turns 61 drops to cut starting point A, and makes cutting wheel 61 and glass plate 2 forceful contact。When forceful contact, cutting wheel 61 fine rotates or swings, thus to form indenture B at this starting point A place。Then, from this indenture B, cutting wheel 61 is made to start cut when forceful contact, to be consequently formed from the indenture B continuous score line C started。
The method is every time formation score line C, at starting point A place cut formation indenture B, and from the method that this indenture B starts cut。
Therefore, when from when passing through to carry out cut in the indenture B that starting point A cut is formed, it is possible to produce continuous print vertical crack from indenture (starting point A), without occurring cutting wheel from the slip of starting point A, thus can realize good bending and fracture。
Additionally, due to cutting wheel 61 is from indenture B, so the center of indenture B and score line C are mutually aligned。
