Description

Method and apparatus for forming sheet glass {Casting Method of Art Sheet Glass and Apparatus therefor}

The present invention relates to a method and apparatus for forming a piece of plate glass on one or both sides of the plate glass and to enable continuous production of the plate glass, and more specifically, by a single process in a conventional furnace (Furnace) The present invention relates to a plate glass forming method and apparatus for forming a piece of glass on both sides of the continuous and conventional glass plate production process, which was inevitably produced, and only one side of the glass plate.

In order to protect privacy and enhance the aesthetics of the building, the glass plate with one or two sides is carved in various ways as a building material for interior and exterior of buildings, and demand is increasing rapidly. It is well known that producers are also trying various methods to increase production efficiency in order to meet the changing needs of consumers as well as the increase in demand.

In the case of the conventionally used method to explain by way of example, in the case of patterned glass in general, when the glass passes through the forming roller in the process of extruding the glass into a predetermined shape and shape in a liquid state, various patterns are formed or predetermined The method of forming a pattern through post-processing on the plate glass solidified to the specification has been used. However, such patterned glass can be produced through an automated process using a roller, etc., but it is possible to produce relatively large quantities, but most of them have to form small patterns repeatedly. Along with this, there has been a lack of provision for the unique piece of glass that consumers demand.

In addition, with reference to the accompanying Figures 6 to 8 of the conventional method and apparatus used to provide such sculpted panes, a heating panel (1) inside the furnace (910), which is not movable or limited in movement only, is first described. 930 is combined and mounted. In addition, after the molding mold 940 is formed on the heating panel 930 by molding with a plaster, clay or metal, and a predetermined pattern 941 is formed thereon, the upper part of the molding mold 940 is formed of flake plate glass. The plate glass 920 which becomes a raw material is put up. In addition, the temperature of the inside of the furnace 910 is increased by the heating action of the heater device 911 provided in the furnace 910 and the temperature of the plate glass 920 is also increased. Normally, the temperature is gradually increased to the strain point (strain point: dir 490 degrees) when the plate glass starts to deform, and the temperature at which the plate glass is brought into close contact with the forming mold 940 by dissolving action is reached. It will quickly rise to the slumping point (about 650 to 800 degrees). In this case, the plate glass 920 fills the pattern 941 of the forming mold 940 in the stretched state as shown in FIG. 8B. Thereafter, after rapidly cooling the temperature to an annealing point (about 575 degrees to about 480 degrees), the temperature is gradually lowered to room temperature. The glass sheet thus produced is bent from the forming mold 940 as shown in FIG. 8C and then packaged into a product through a process of being commercialized in the state as shown in FIG. 8D or being cut or further processed by an operator. The furnace 910 is capable of raising and lowering the temperature by using various electric devices. For example, in the case of the furnace 910 using electricity, a heating wire 931 or the like is provided on the bottom or side of the heating panel 930. In some cases, the switch 950 and the temperature controller 960 are inserted and formed to further open and close electricity.

Hereinafter, the main terms used in the present specification will be described.

The strain point refers to the temperature at which the pane begins to deform due to heating and is usually about 490 degrees Celsius. Slumping point (Slumping Point) refers to the temperature at which the plate glass started to deform at the strain point is in close contact with the forming mold while sagging by gravity or weight, and generally corresponds to about 650 to 800 degrees Celsius . The softening point means the starting temperature for reaching the slumping point and sagging by gravity or weight, and the plate glass adhered to the molding frame again to solidify, which is generally about 575 degrees Celsius. . Lastly, annealing point means a temperature of about 480 degrees from the softening point. In general, in the forming process of plate glass, the slumping point to the softening point is quenched, and then the quenching process is performed. It is unstable enough to maintain the transparency of the glass and maintain its strength through a slow cooling process that slowly lowers the temperature from annealing point to room temperature without removing the glass from the furnace. . In addition, the temperature of each point or point specified above is a general light oil, it will be possible to vary the temperature according to the material or size of the glass plate.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a block diagram illustrating a slice plate glass forming apparatus according to the present invention, Figure 2 is a flow chart illustrating a method for forming a slice plate glass according to the present invention, Figure 3 is to complement the heating panel and the molding frame according to the design It is sectional drawing explaining. When the present invention is described in detail with reference to the drawings, firstly, a producer forms a lower molded mold 120 and a sculpture in which a three-dimensional pattern 121 that is to operate the lower surface of the sliced plate glass is formed in order to produce a desired sliced plate glass. After manufacturing the upper molding die 200 is formed in the three-dimensional pattern to sculpt the upper surface of the plate glass (s111), and after combining the manufactured lower forming die 120 to be fixed to the heating panel 110 In order to produce a desired piece of plate glass, the size and thickness is calculated and cut the plate glass 130 is mounted on the upper portion of the lower mold (120) (s112).

The heating panel 110 generally has a rectangular shape corresponding to the shape of the plate glass 130. When the heating wire 111 is provided on the bottom or side thereof, the heating panel 110 receives electricity and generates heat directly. If possible, if heat is generated in other heater devices 311 and 321, it will be possible to conduct it and transfer it to the plate glass 130. Thereafter, the heating panel 110 on which the plate glass 130 is mounted is placed on the conveyor apparatus 400a provided outside the furnace 300 and transferred to the inside of the first furnace 310 by the rotation of the conveyor apparatus 400a. To be drawn (s121).

In this case, the first furnace 310 operates a heater device 311 provided separately in the first furnace 310 or supplies electricity to the heating wire 111 provided in the heating panel 110. It generates heat by raising the temperature of the plate glass 130, and the temperature of the plate glass 130 is gradually raised (s122) to the strain point (s122) of about 490 degrees Celsius, which causes the plate glass 130 to deform. When the temperature of the plate glass 130 rises to the point of distortion and the plate glass starts to deform, the temperature of the plate glass 130 is quickly increased to the slumping point of about 650 degrees Celsius to 800 degrees Celsius. The plate glass 130 is struck by its own weight so that the lower piece is formed (s123). At this time, the inside of the first furnace 310 is also provided with a conveyor device (400b) to gradually move the heating panel 110 on which the plate glass 130 is mounted at a time and speed and direction specified by the user or the control device, etc. Let's go. When the temperature rises to such a slumping point and the plate glass 130 comes into close contact with the lower upper mold 120, the heating panel 110 on which the plate glass 130 is mounted is located inside the first furnace 310. The conveyor apparatus 400b is transferred to the conveyor apparatus 400c of the second furnace 320 and transferred to the inside of the second furnace 320 (s131). In this case, the second furnace 320 operates a heater device 321 provided separately in the second furnace 320 or supplies electricity to the heating wire 111 provided in the heating panel 110. The heat is generated by the heat to maintain the temperature of the plate glass 130 in a desired state, the temperature of the plate glass 130 is rapidly lowered (s132) to a softening point (s132) of about 575 degrees Celsius, the second furnace ( Lowering the upper molding frame 200 provided at one side end of the upper portion of the 320 to compress the plate glass 130 in a softening state to form the upper piece (s133). At this time, the power for the lowering and raising of the upper mold 200 of the porcelain will be able to be supplied from the pressure pump 210, etc. formed on the outside of the second furnace 320, the device structure of the pressure pump 210 And the principle of operation is conventional and will not be described in detail herein. When the upper surface of the plate glass 130 is manipulated by the upper mold 200, the upper mold 200 is raised and restored to its original position, wherein the heating panel 110 is inside the second furnace 320. By the conveyor device 400c provided in the user or the control device is moved in the specified direction. At this time, the temperature of the plate glass 130 with the upper mold 200 removed is about 575 degrees Celsius, which is still a softening point, or 480 degrees Celsius, at a temperature of about 575 degrees Celsius, which is the temperature of the slow cooling point, inside the second furnace 320. Although it is maintained to a degree, in order to maintain the transparency and strength of the glass, the temperature is gradually lowered to a temperature close to or close to room temperature, thereby slowly cooling (s134). The plate glass 130 and the heating panel 110 in which the slow cooling is completed are transferred from the conveyor apparatus 400c in the inside of the second furnace 320 to the conveyor apparatus 400d in the outside of the second furnace 320 and thus outside. And the user is to be separated (s141) from the lower forming mold 120, which is coupled to the heating panel 110, the plate glass 130, the lower and the top of the carved state.

4 and 5 are cross-sectional views illustrating the process of forming the shaping plate glass according to the present invention, by dividing the code of the plate glass 130 by the code of 131 to 134 to separate the process of forming the plate glass Explain.

4A is a state in which the plate glass, which is a raw material for shaping the plate glass, maintains its original shape 131, and is generally in the process of increasing in temperature to the strain point (about 490 degrees Celsius) inside the first furnace. It is a shape. 4B is a shape 132 in which the pane is struck by gravity or its own weight and is in close contact with the lower forming mold, typically in the interior of the first furnace to a slumping point of about 650 degrees Celsius to 800 degrees Celsius. Appears when temperature rises. FIG. 4C is a view in which the upper forming mold 200 descends to form an upper pattern on the plate glass having a shape 132 in close contact with the lower forming mold, and FIG. 4D shows the lower forming mold by the upper forming mold 200. The plate glass is in close contact with the shape 133 is pressed. After this process, the shape of the plate glass 134 in which the pattern is finally manipulated on the lower part and the upper part is shown in FIG. 4D. The upper pattern of the plate glass can be changed depending on the shape of the upper mold 200, as shown in Figure 5a, if the shape of the upper mold 200 is formed of an ellipse of a semicircle the upper pattern of the glass also Corresponding to the shape is a piece 134 into a semi-circular ellipse shape, which is shown in Figure 5b.

The shape of each furnace described above and the shape of the conveyor apparatus may be changed or added according to the size and application. For example, the process of sculpting the upper surface of the plate glass by dividing the second furnace into the second furnace and the third furnace and the plate glass. It may be possible to separate the process into a slow cooling process, and in the case of the conveyor apparatus, at least one inside each furnace may be interconnected, or the first furnace, the second furnace, and the external conveyor apparatus may be configured as one large conveyor apparatus. It would be possible to do so. In addition, it is also possible that the user can proceed manually by using a shelf or the like by omitting the conveyor device outside each furnace (Furnace) of these conveyor devices.

In addition, the conveyor apparatus 400 may include only the conveyor roller 401 without the conveyor belt 402. In this case, the heating panel 110 may be directly mounted on the conveyor roller 401.

So far we looked at the preferred embodiment according to the present invention in detail. The scope of the present invention is not limited to the above-exemplified embodiments, and if the technical idea of the present invention is applied, all will be said to belong to the scope of the present invention.

The present invention relates to a method and apparatus for forming a piece of plate glass on one or both sides of the plate glass and to enable continuous production of the plate glass, and more specifically, by a single process in a conventional furnace (Furnace) The present invention relates to a plate glass forming method and apparatus for forming a piece of glass on both sides of the continuous and conventional glass plate production process, which was inevitably produced, and only one side of the glass plate.

It can be produced through automated processes using rollers, so it is possible to produce relatively large quantities, but most have no choice but to repeatedly form small patterns, and because the depth of the patterns is limited, consumers have various disadvantages as well as disadvantages in the three-dimensional pattern. The problem of the conventional patterned glass which could not cope with an original request,

The disadvantage of the fact that the pattern can be formed on only one side, and the opposite side with the pattern is that the surface is not smooth and uneven and has to be finished by a separate process of the producer, and in one furnace According to the present invention, which solves the problems of the conventional patterned cages and sculpted plate glass, in which only a slate plate can be produced, such that a continuous production plant is impossible and its production efficiency is significantly reduced.

Both the continuous production process of the sliced glass and the two-side molding process of the sliced glass is possible, so that it is possible to produce and supply various sliced glass faster and cheaper.
