Description

Flat Glass Embossing Machine for Groove Simultaneous Molding {FLAT GLASS EDGE AND GROOVE SIMULTANEOUS FORMING MACHINE}

The present invention relates to a plate glass embossing machine capable of simultaneously forming a plate glass groove, and more particularly, in the process of forming an angled surface perpendicular to the upper and lower plate surfaces of the plate glass by polishing and polishing a cut surface of the plate glass. The present invention relates to a flat glass double-sided face machine capable of forming a groove simultaneously with forming a groove along the longitudinal direction of each face at the center of each face.

When cutting wide panes to make several small panes, the cut surface is not smooth, does not form an exact right angle with the upper and lower surfaces, and partially sharp portions remain. Therefore, after cutting the plate glass, the cut surface is ground by a certain amount with a diamond wheel, and then polished smoothly, thereby forming a smooth angled surface at right angles with the upper and lower plate surfaces of the plate glass. In general, diamond wheels are sintered using diamond powder as a cutting material and metal powder such as copper (for rough polishing) or resin (for fine polishing) as a binder.

Although each side may be molded one by one, Korean Patent No. 10-897750 discloses a flat glass embossing machine for processing opposing embossed surfaces at a time.

Each face formed in this way forms a right angle with the upper and lower plate faces, and thus, the edge between each face and the upper and lower plate faces is fragile, and this may cause damage to the body due to this edge during the handling of the operator. (An inclined plane) may be formed. Diamond wheels are also used for shaping this ear canal. In general, the shaping of each face and the ear canal is made by separate polishing equipment, and the most commonly used plate glass chamfer for ear canal shaping is described in Korean Utility Model Publication No. 1999-0022831.

In recent years, the use of glass panes as door panels, wall panels, partition panels, furniture panels, etc., the use is spreading. When the pane is used for this purpose, the assemblability between the pane and the assemblage between the pane and the adjacent parts are critically required. When grooves (grooves) are formed along the longitudinal direction at the center of each side of the pane, not only the assemblability between the panes but also the assemblability between the pane and the adjacent parts is greatly improved.

Groove shaping for each side of the pane is now done by hand. However, it is very difficult to form grooves along each side by hand using a grinder.

The planar rectangular plate glass has a very large upper and lower plate surface (surface area), while each surface has a very narrow straight band shape. In case of manual process, each side should be processed one by one. In addition, the plated glass on each facet of the facet machine must be transported to another place for shaping the grooves by hand. In addition, a separate jig, a transfer device, a fixing device, etc. should be provided for groove forming by hand.

Therefore, when the groove is formed by hand, it is difficult to form a groove that proceeds straight to a certain width and depth, and when the groove is formed on one side surface and the groove is formed on the opposite side surface, the pressing force and The impact is likely to damage the grooves and facets already formed, and it is difficult to form grooves of the same depth on both facets. In addition, there is a problem that may damage the part or the whole of the glass plate during conveying the plate glass of the face-face processing for the groove manually or during the groove manually forming process on the grinder. In addition, when molding the grooves by hand, too much time is required to form one groove of the plate glass, there is a problem that the productivity is lowered.

The present invention has been made in order to solve the above-mentioned problems in forming grooves on each side of the plate glass, the first problem to be solved by the present invention is to form each side of the plate glass, double-sided molding and groove forming between the molding equipment And a flat glass embossing machine capable of simultaneously forming grooves which can be finished in one process without moving in place.

The second problem to be solved by the present invention is to provide a flat glass embossing machine capable of simultaneously forming grooves that can quickly form grooves that proceed straight along a length and width of each side.

The third problem to be solved by the present invention is to provide a flat plate glass embossing machine capable of co-molding the groove can be easily formed in the groove edge.

The first and second objects of the present invention described above are provided on both sides of the plate glass conveyor belt for conveying the horizontally laid plate glass in a straight direction, and are provided with a face grinding wheel capable of polishing both cut surfaces of the plate glass, and the rear end of the face polishing wheel. In (iii), a pair of braid shank type diamond saws capable of forming grooves smaller than the thickness of each surface along the longitudinal direction of each surface processed by the surface polishing wheels are fixedly installed on both sides of the conveyor. Thus, the pair of diamond saws are achieved by forming grooves while simultaneously pressing both sides of the pane at the same pressure.

The third object of the present invention described above is an ear canal polishing wheel which can form an ear canal by simultaneously chamfering both side edges of the plate glass at the rear end of the diamond saw in the up and down slope direction, and an ear canal formed by the two ear polishing wheels. This is achieved by sequentially installing more two-way polishing wheels to smooth out the ridges.

A rear surface polishing wheel may be further installed at the rear end of the two-sided polishing wheel to smoothly smooth each surface on which the groove and the two-sided surface are formed.

A groove two-sided wheel may be further installed at the rear end of each of the polishing wheels, wherein the grooved two-wheeled wheel has a disc-shaped core inserted into the groove, and a disc-shaped tapered abrasive wheel attached symmetrically to the upper and lower surfaces of the core and having an inclined outer circumferential surface. It is preferable that it consists of.

According to the above-described configuration, the present invention can not only collectively finish faceting, double-faced shaping, and groove shaping of the plate glass in one process without the movement between the molding equipment and place, but also straightening along the longitudinal direction of each face. It is possible to quickly form a groove that proceeds to a constant width and depth, there is an effect that can easily form the ear canal in the groove edge. Moreover, according to this invention, there exists an effect which can form the depth of the groove formed in each surface of both sides of plate glass equally and uniformly.
