[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method of filling a caulking material in a glass top plate for a stove comprising a glass plate and an outer frame surrounding the glass plate, and a glass top plate for a stove.
[0002]
[Prior art]
Conventionally, in this type of glass top plate, a concave receiving edge is formed on the outer frame to receive the back surface of the peripheral portion of the glass plate, and the caulking material is formed in the gap between the rising portion of the outer periphery of the receiving edge and the glass plate. Filled.
[0003]
When filling the caulking material, the discharge nozzle of the caulking material is moved by the automatic machine so as to make one round of the glass plate along the gap, and the caulking material is automatically filled in the gap over the entire circumference.
[0004]
[Problems to be solved by the invention]
By the way, when the discharge of the caulking material from the discharge nozzle is started, the caulking material swells into a large droplet shape from the tip of the nozzle due to the surface tension, and this droplet-shaped caulking material moves to the filling start point of the caulking material to fill it. The starting point is filled with caulking material excessively, and the caulking material rises compared to other parts. Here, the filling portion of the caulking material is a gap between the rising portion of the outer periphery of the receiving edge of the outer frame and the glass plate, and appears on the appearance. Therefore, if the caulking material rises at the filling start point, the appearance is impaired. For this reason, it is necessary to level the rise of the caulking material after filling, which is a problem in improving productivity.
[0005]
In view of the above points, the main object of the present invention is to provide a method for filling a caulking material in a glass top plate for a stove so that the caulking material can be filled without causing a rise at the filling start point.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention is a method for filling a caulking material in a glass top plate for a stove comprising a glass plate and an outer frame surrounding the glass plate, and is formed on the outer frame, and the rear surface of the peripheral portion of the glass plate The caulking material is filled with the caulking material by moving the discharge nozzle of the caulking material so as to make one round of the glass plate along the clearance in the gap between the rising edge of the outer periphery of the receiving edge of the recessed shape receiving the glass plate and the glass plate , A volume increasing portion in which the volume of the gap is made larger than that of the other portion is formed in a part in the circumferential direction of the gap, and filling of the caulking material is started from this volume increasing portion.
[0007]
At the starting point for filling the caulking material, the caulking material that swells in the form of droplets moves to the tip of the nozzle and the amount of filling of the caulking material increases. In the present invention, the starting point for filling is the volume increasing portion. Therefore, the increase in the filling amount is offset by the increase in the volume of the gap, and the caulking material does not rise at the filling start point. This eliminates the need for leveling work after filling and improves productivity.
[0008]
By the way, each corner around the glass plate is generally formed in a rounded shape in order to avoid cracking of the glass plate due to stress concentration. On the other hand, when the outer frame is configured by combining a straight frame material such as an aluminum extrusion molding material, each corner around the rising portion is formed in a rounded shape, and the width of the gap is the corner. Becomes larger and the volume of the gap becomes larger. Therefore, by starting the filling of the caulking material with the gap portion at any one of the corners as the volume increasing portion, the rising of the caulking material at the filling start point can be prevented. When the discharge nozzle is moved at a constant speed over the entire circumference of the gap, the filling amount of the caulking material is insufficient with respect to the volume of the gap in the corner portion other than the corner portion where the filling of the caulking material is started. Causes caulking dents. Therefore, in the corner portion other than the corner portion where the filling of the caulking material is started, the moving speed of the discharge nozzle is reduced to increase the filling amount of the caulking material so that the caulking material is not dented at the corner portion. It is desirable.
[0009]
In addition, when the gap is substantially the same width over the entire circumference, the recess depth is set from the other part so that the caulking material filled in the gap flows into a part of the circumferential direction of the receiving edge. A deepened depression is formed, and this depression is used as the volume increasing portion, and filling of the caulking material may be started from here.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, reference numeral 1 denotes a glass top plate for a built-in stove. The glass top plate 1 is composed of a rectangular glass plate 2 made of ceramic glass and an outer frame 3 surrounding the glass plate 2, and is supported by a counter top (not shown) via the outer frame 3. The glass plate 2 has three stove openings 2a that allow the stove burner to face. The corners at the four corners of the periphery of the glass plate 2 are formed in a rounded shape in order to avoid cracking of the glass plate 2 due to stress concentration.
[0011]
The outer frame 3 is configured by combining a plurality of straight frame members made of an extruded aluminum material into a frame shape. That is, a rectangular frame is assembled with the frame material 30 for the front side, the frame materials 31 and 31 for the left and right sides, and the frame material 32 for the rear side, and further in front of the frame material 32 for the rear side. In parallel with this, a partition frame member 33 is assembled, and an outer frame 3 is formed by defining a grill exhaust port 34 between the rear frame member 32 and the partition frame member 33, and the front frame 3 is formed. The glass plate 2 is mounted in a square space surrounded by the side frame member 30, the left and right side frame members 31, 31 and the partition frame member 33.
[0012]
As shown in FIG. 2, the front side frame member 30, the left and right side side frame members 31, 31, and the partition frame member 33 have recessed receiving edges 3 a that receive the rear surface of the peripheral portion of the glass plate 2. The caulking material 4 is filled in the gap between the rising portion 3 b on the outer periphery of the receiving edge 3 a and the glass plate 2. A plurality of spacers 5 are attached to the receiving edge 3a at intervals in the circumferential direction, and the spacer 5 secures a gap between the receiving edge 3a and the back surface of the glass plate 2, and this gap Also, the caulking material 4 flows in. As the caulking material 4, for example, silicone rubber containing an adhesive is used, and the gap is filled by filling the caulking material 4, and the glass plate 2 is fixed to the outer frame 3.
[0013]
As shown in FIG. 3, the caulking material 4 is filled in a movable rail 102 that is movable in the X-axis direction along the guide rail 101, and a caulking material discharge nozzle 103 is movable in the Y-axis direction via a slider 104. Using the two-axis orthogonal coordinate automatic machine 100 that is supported, the discharge nozzle 103 is moved along the gap between the rising portion 3b of the outer frame 3 and the glass plate 2 so as to make one round of the glass plate 2. To do. By the way, at the filling start point, the caulking material that swells in the form of droplets due to surface tension from the nozzle tip at the beginning of discharge moves, and the amount of filling of the caulking material becomes excessive, and the caulking material 4 rises as compared with other parts. It becomes easy.
[0014]
Here, each corner around the glass plate 2 is formed in a rounded shape as described above, but each corner around the rising portion 3b is formed by combining the outer frame 3 with a straight frame material. As a result of the configuration, it is formed in a shape having no rounded shape, the width of the gap between the rising portion 3b and the glass plate 2 becomes wider at these corners, and the volume of the gap becomes a larger volume increasing portion than the other portions. Therefore, in the present embodiment, the caulking material 4 is filled with the gap portion a in one of these corners, for example, the right rear corner, as a filling start point. According to this, the increase in the filling amount at the filling start point is offset by the increase in the gap volume, and the caulking material 4 does not rise at the filling start point. Further, in the remaining gap portion, that is, the gap portion b in the right front corner portion, the gap portion c in the left front corner portion, and the gap portion d in the left rear corner portion, the discharge nozzle 103. And the filling amount of the caulking material 4 in these portions b, c, d is increased so that the caulking material 4 is not dented in these portions b, c, d.
[0015]
FIG. 4 shows another embodiment of the stove glass top plate 1, and the outer frame 3 is formed of a stamped press molded product of a metal plate such as stainless steel. In this case as well, as shown in FIG. 5, the outer frame 3 is formed with recessed receiving edges 3a for receiving the rear surface of the peripheral portion of the glass plate 2 through spacers 5 at a plurality of positions in the circumferential direction, and the outer periphery of the receiving edge 3a. The caulking material 4 is filled in the gap between the rising portion 3b and the glass plate 2 by the automatic machine 100 shown in FIG. An intermediate grill exhaust port 34 and hot air exhaust ports 35 in the stove on both the left and right sides thereof are opened at the rear side of the outer frame 3.
[0016]
In this embodiment, each corner around the rising portion 3b is rounded with each corner of the glass plate 2, and the gap between the rising portion 3b and the glass plate 2 extends over the entire circumference. It is almost equal. Therefore, as shown in FIG. 6, a recess 3c having a deeper insertion depth than the other part is formed at a part in the circumferential direction of the receiving edge 3a, for example, at the center of the rear side of the receiving edge 3a, and the rising part 3b. The caulking material filled in the gap between the glass plate 2 and the glass plate 2 flows into the recess 3c. Accordingly, the gap portion that coincides with the recess 3c becomes a volume increasing portion having a larger volume than the other portions. Then, the caulking material 4 is filled using this portion as a filling start point so that the caulking material 4 does not rise at the filling start point. In this case, the discharge nozzle 103 is moved at a constant speed over the entire circumference.
[0017]
In this embodiment, the recess 3c extends from the portion of the receiving edge 3a facing the gap between the rising portion 3b and the peripheral edge of the glass plate 2 to the portion of the receiving edge 3a facing the back surface of the glass plate 2. It is formed in size. According to this, even if the dent depth is made shallower than when the dent portion 3c is formed only in the portion of the receiving edge 3a facing the gap between the rising portion 3b and the peripheral edge of the glass plate 2, the required volume can be reduced. It can be secured and processing becomes easy. Further, in this embodiment, as in the previous embodiment, the caulking material is also allowed to flow into the gap between the receiving edge 3 a secured by the spacer 5 and the back surface of the glass plate 2. In this case, you may form the hollow part 3c only in the site | part of the receiving edge 3a facing the back surface of the glass plate 2. FIG.
