Description

Automatic grinding device for finishing side of cut part of plate glass{AUTOMATIC GRINDING APPARATUS FOR FINISHING SIDE OF CUTTING PART OF PLATE GLASS}

The present invention relates to an automatic polishing apparatus for finishing by automatically polishing the cut surface of a plate glass, and more specifically, to improve the function and performance through the improvement of the structure of a conventional conveyor type automatic polishing machine. Finishing the side of the cut glass to enable shorter cycle times and to improve productivity, and to set the cut glass to the correct mounting position at the stage before the polishing process starts when the cut glass is put into the automatic polishing machine. It relates to an automatic polishing machine for dragons.

In general, plate glass (Plate Glass) is mainly produced by the demand of construction companies and furniture companies, it is a constant cutting of large plate glass.

Looking at the manufacturing process of the plate glass, a large plate glass is put into a table, cut into a finished product standard in a rectangular shape, polished by polishing the side of the cut portion of the plate glass, and then cleaned and inspected.

At this time, the cutting part side polishing process of polishing the side of the cut part of the plate glass to finish is a process of finishing the sharp side of the cut part of the rectangular plate glass with a polishing machine. Conventionally, both sides of the cut part of the plate glass are simultaneously polished through a conveyor type automatic polishing machine. have.

Here, as a polishing operation using a conveyor type automatic grinder used in the side surface polishing process of a conventional plate glass, the cut glass is conveyed through a conveyor for standardization, and the side of the cut portion is vertical to the plate glass conveyed through the conveyor. Direction) and the upper chamfer (45˚ direction) and the lower chamfer (45˚ direction), each of the three parts on each side is polished to be continuously polished.

In addition, the conveyor type automatic polishing machine for the side surface polishing process of the cutting portion of the plate glass is driven at a constant speed when the plate glass is put into the equipment to be inserted and mounted at the correct processing position by a conveyor having a transport movement. It is configured to include an operating mechanism.

Incidentally, in the conventional conveyor type automatic polishing machine, two stoppers for driving downward are provided on the input side of the equipment, and when the plate glass is put into the equipment, on both sides of the input side of the equipment through the control system of the controller. The two stoppers provided are driven downward to support the plate glass for 3 seconds, and are accurately inserted and mounted at the abrasive machining position in the equipment by the movement of the conveyor conveyed while being supported by the stopper.

That is, by supporting the plate glass that is input through the stopper, the plate glass is prevented from being twisted into the equipment, and product defects are prevented.

Subsequently, while continuously processing the plate glass by a conveyor, a polishing operation is performed to automatically perform finishing operations such as cutting side and upper chamfering and lower chamfering continuously.

By the way, the conveyor type automatic polishing machine for the side surface polishing process of the cutting portion of the conventional plate glass having the stopper operation mechanism as described above is provided with a stopper on the input side of the equipment and the dwell time in which the operation is temporarily delayed due to the mechanism for operating it when the plate glass is input. There was a problem in that (dwell time) occurs, and due to such dwell time, there are significant difficulties in shortening the cycle time for production, and there are difficulties in improving productivity.

In addition, since it is difficult to continuously input the plate glass due to the occurrence of the dwell time, and the plate glass must be re-inserted after the dwell time of 3 seconds, the working time becomes longer and the cycle time for production is inevitably increased.

Furthermore, there is a problem in that it is difficult to meet the delivery date due to a decrease in production volume, and the worker's fatigue is also increased, such as the worker's working time increases in order to cope with the production volume.

In addition, an attempt is made to increase the moving speed of the conveyor in order to make up for the above-mentioned problems, but rather, problems such as quality defects caused by abrasive work and damage to the abrasive wheel occur.

On the other hand, when looking at the prior art literature related to the automatic polishing apparatus for finishing the side of the cut portion of the plate glass, Korean Patent Publication No. 10-2009-0070523 proposes and discloses a plate glass polishing apparatus using a plate glass conveying method. When two adsorption transfer units are adsorbed and transported, one adsorption transfer unit polishes the n-th plate glass, and another adsorption transfer unit prepares to polish the n+1th plate glass, thereby reducing production time. Regarding the transfer type polishing apparatus, it can be said that it has a considerable technical difference from the technology of the present invention to be proposed below.
