Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a glass cutting device having a function of printing fixed point marks on two or more positions of cutting coordinates on the glass when the glass to be chamfered or engraved is cut in a post-step of cutting the glass. It is a thing.

[0002]

[Prior art]

 Conventionally, when chamfering the left and right or top and bottom of the cutting line of flat glass cut with a glass cutting device, chamfering is performed simultaneously with the cutting of glass with a Y-type cutter, or it is continuous after chamfering by combining V-type and I-type cutter And then disconnect. However, when chamfering only one side outside or inside the cutting line of the sheet glass cut by the glass cutting device, the cut sheet glass is transferred to the chamfering device, and the chamfering device is not contacted with the chamfering device in advance. The chamfering grinder runs the simulation along the cutting coordinates of the cutting plate glass stored in the NC control unit, and repeats this trial until the cutting line of the cutting glass and the trajectory of the simulation run match, and when it matches, the chamfering Work is starting. On the other hand, also in the case of engraving, similarly, the engraving grinder is made to run along the cutting coordinates of the cutting plate glass stored in the NC controller of the engraving device in advance, and the cutting line of the cutting glass and the trajectory of the simulation match. This trial is repeated until the same time, and when they match, the engraving work is started.

Usually, it takes about 2 hours for the cut surface of the cut glass and the trajectory of the simulation run of the processing device in the subsequent process to coincide with each other. In general, the productivity of chamfering or engraving work is about 1/10 times the productivity of cutting work on average, and in addition, if a waiting time of about 2 hours occurs in the chamfering or engraving alignment step, This difference in productivity is further widened, and more than 10 chamfering devices or engraving devices are required for each cutting device, and an increase in equipment cost is unavoidable, and chamfering glass and engraving are inevitable. The current situation is that glass prices are soaring.

[0004]

[Problems to be solved by the device]

 It is an object of the present invention to provide a glass cutting device that efficiently and economically solves the above-mentioned problems of the prior art.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a glass cutting device provided with a printing device for providing fixed point marks at two or more positions of the cutting coordinates on the surface of the glass to be cut.

[0006]

[Action]

 Since the present invention uses the above means, it is possible to make fixed point marks on the surface of the glass to be cut on the surface of the glass to be cut at two or more positions of the cutting coordinates of the cutting glass. If a print mark reading device is installed at a position corresponding to the print mark at a fixed point on the cutting coordinates of the glass to be cut, the print chamfering device or the engraving device will perform the print mark reading on the print mark reading device. By manually moving the glass chamfering device or engraving device to the position where it can be read, the cutting coordinates of the glass to be cut and the processing coordinates of the processing glass can be matched in about 15 minutes without performing the simulation run. it can. The chamfering device or the NC control device of the engraving device stores in advance the glass cutting coordinates of the glass cutting device, the positions of two or more fixed point marks made on the cutting coordinates, and the tracking traveling control software of the fixed point mark. Then, just turning on the NC processing start signal of the processing device will complete the setting of the device to the processing start position such as chamfering or engraving in 5 minutes or less, and then the setting operation Is automatically implemented. The productivity of the line chamfering device or engraving device is dramatically improved by about 8 times or more. Therefore, the required number of line chamfering device or engraving device can be reduced and labor can be saved. The processing cost for chamfering or engraving glass products will be greatly reduced.
