Description

The present invention relates to a method for manufacturing a top plate for stoves as a component of stoves such as gas stoves and IH stoves.

As a top plate of a gas stove, there is a glass top plate using a glass plate (see Patent Document 1, for example). The glass top plate has a good appearance and can give a sense of luxury, and is also excellent in cleanability when boiling over occurs.

In such a glass top plate, printed layers are often provided on the front and back surfaces of the glass plate forming the main part to further improve the appearance. However, as a means for providing the printed layer, conventionally, a printed layer is provided by directly applying an ink for glass to the surface of a glass plate by screen printing, and this is heated at a high temperature to form a glass plate. A method of baking to the surface is often employed.

However, the prior art still has room for improvement as described below.

That is, conventionally, screen printing is performed as a means of providing a printing layer on a glass plate, so a plate for screen printing is required, and the setup change work when changing the color pattern is complicated. . In addition, since it is necessary to print for each color, the printing work itself is also complicated. For this reason, it lacks speed and flexibility, and is not very suitable for high-mix, low-volume production. As a result, conventionally, when manufacturing a plurality of types of stoves, it is necessary to manufacture and prepare in advance a plurality of types of top plates each having a desired printed layer on a glass plate in an expected quantity. As a result, the inventory quantity of the top plate increases, and the cost burden becomes large.

JP 2014-20646 A Japanese Patent No. 4016730

The present invention has been devised under the circumstances as described above. An object of the present invention is to provide a method for manufacturing a top plate for stoves that eliminates the need to keep a large inventory.

In order to solve the above problems, the present invention takes the following technical measures.

A method for manufacturing a stove top plate provided by the present invention comprises a preparation step of preparing a transfer sheet having a printed layer, and bringing the transfer sheet into contact with one side corresponding to the back surface of a glass plate constituting a stove top plate. a transfer step of transferring the printed layer to the glass plate by allowing the printed layer to be transferred, and a baking step of heating the transferred printed layer and baking it on the glass plate after the transfer step , A method for manufacturing a stovetop top plate, wherein an additional printed layer displaying stove-related information is provided by inkjet printing as an additional transfer sheet separate from the transfer sheet, and the additional printed layer is protected. The step of preparing an additional transfer sheet further provided with a clear layer is further provided, and in the transfer step, the additional transfer sheet is brought into contact with the standing surface of the glass plate, and the standing surface The additional printed layer and the clear layer are transferred to the glass plate, and in the baking step, the transferred printed layer, the additional printed layer, and the clear layer are baked on the glass plate at the same time.
Here, the standing surface is a surface standing upright in the thickness direction of the glass plate, and an example thereof is the outer peripheral side surface of the glass plate.

According to such a configuration, the following effects are obtained.
That is, as a means of providing a printed layer representing a desired pattern on a glass plate, transfer printing means using a transfer sheet is adopted, so when changing the pattern etc., only the transfer sheet is changed. There is little or no need to change the transfer process itself and the printing process itself. Compared to the conventional technology in which a printed layer is provided on a glass plate by screen printing, it is possible to change the pattern easily and quickly, and the productivity is good, making it suitable for high-mix low-volume production.
On the other hand, when manufacturing many types of stoves, prepare multiple types of transfer sheets and flexibly transfer the printed layer to the glass plate according to the manufacturing situation of the stove, and use the top plate for the stove. It should be completed. Therefore, unlike the prior art, it is no longer necessary to keep a large inventory of stove top plates provided with printed layers. For this reason, the manufacturing cost of the stovetop top plate can be reduced.
Since the printed layer is provided on the back surface of the glass plate, the printed layer is not easily damaged.
Furthermore, an additional printed layer can be efficiently provided on the standing surface of the glass plate. In addition, the standing surface of the glass plate can be used to display stove-related information in a space-efficient manner.

In the present invention, preferably, the printed layer of the transfer sheet has a configuration in which a colored pattern printed layer, a white printed layer, and a dark printed layer are laminated in this order, and in the transfer step, the glass The printed layer is transferred so that the colored pattern printed layer adheres to the one side of the plate, and the white printed layer and the dark colored printed layer are sequentially laminated on the colored pattern printed layer. .

According to such a configuration, when the manufactured stove top plate is viewed from above, the white printed layer exists in the background of the colored pattern printed layer, so that the colored pattern printed layer has the originally intended color. It is possible to make it visible. In addition, the dark-colored printed layer plays a role in preventing spilled liquid or oil from being seen from above the stovetop top plate when, for example, boiled over liquid or oil enters the lower part of the stovetop top plate. It plays a role in improving the appearance of the plate.

Other features and advantages of the present invention will become clearer from the following description of embodiments of the invention with reference to the accompanying drawings.

It is a perspective view which shows an example of the top plate for stoves. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1; 2 is a schematic perspective view showing an example of a stove provided with the stove top plate shown in FIG. 1. FIG. 3(a) to 3(d) are cross-sectional views of essential parts showing an example of a method of manufacturing the stove top plate shown in FIG. 2. FIG. (a) is a side view of a main part showing an example of a stovetop top plate manufactured by the manufacturing method of the present invention, and (b) is a cross-sectional view taken along the line Vb-Vb of (a). 6A to 6D are cross-sectional views of essential parts showing an example of a method of manufacturing the stove top plate shown in FIG. 5. FIG.

Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

1 and 2 show a stovetop top plate A to be manufactured. Before describing the method of manufacturing this stove top plate A, the configuration of the stove top plate A will be described below.

The stove top plate A is a component of a stove B such as a gas stove, as shown in FIG. In the figure, reference numeral 51 indicates a trivet.
1 and 2, a stove top plate A includes a transparent glass plate 1 such as borosilicate glass or crystallized glass, and a printed layer 2 provided on the back surface (lower surface) 1a thereof. The glass plate 1 has a substantially rectangular flat plate shape in plan view and has a plurality of stove openings 18 for exposing the stove burners 50 .

The print layer 2 is a transfer print layer provided using a transfer sheet S described later. As shown in FIG. It is the structure laminated|stacked on the back surface 1a of the glass plate 1 in this order.

As shown in FIG. 1, the colored pattern printed layer 20 displays a plurality of dot-like patterns F1 arranged vertically and horizontally at suitable intervals, for example, in a scattered dot pattern. In addition, the stove-related information F2 indicating the manufacturing number of the stove B (eg NR-201) and the stove-related information F3 indicating precautions when handling the stove B (eg Caution XXX) are also displayed. . In addition, in FIGS. 1 and 3, the plurality of dot-like patterns F1 and the stove-related information F2 and F3 should essentially be indicated by dashed lines (hidden lines). It is indicated by a solid line.

The white-based printed layer 21 and the dark-colored printed layer 22 are preferably white and black, respectively. The white printed layer 21 and the dark printed layer 22 are solid printed layers provided without gaps over substantially the entire back surface 1 a of the glass plate 1 . FIG. 2 shows a state in which a gap is formed between the back surface 1a and the white printed layer 21 on the back surface 1a of the glass plate 1 where the colored pattern printed layer 20 is not provided. However, in reality, the white printed layer 21
is in close contact with the back surface 1a, and the gap does not exist (this point is the same in other drawings).

Next, an example of a method for manufacturing the stovetop top plate A will be described with reference to FIG.

First, a transfer sheet S as shown in FIG. 4A is manufactured and prepared (preparation step). The transfer sheet S is a water-sliding type transfer sheet, and has a water-soluble glue layer 31, a printing layer 2 (printing layer for transfer), and a coating layer for temporarily protecting the printing layer 2 on a backing paper 30. 32 are stacked in this order. The printed layer 2 has a configuration in which a colored printed layer 20, a white printed layer 21, and a dark printed layer 22 are laminated. The colored pattern printed layer 20 is an inkjet printed layer printed using an inkjet printer, and displays the above-described multiple dot patterns F1 and stove-related information F2 and F3. The paste layer 31, the white printed layer 21, the dark printed layer 22, and the coat layer 32, excluding the colored pattern printed layer 20, are all solid coatings, and can be easily provided using, for example, a spray coating method. is.

Next, the printed layer 2 of the transfer sheet S is transferred onto one side 1a (corresponding to the back side 1a) of the glass plate 1 (transfer step). As shown in FIG. 4(b), this transfer process is carried out by peeling off the backing paper 30 of the transfer sheet S and contacting the one side 1a of the glass plate 1 with the adhesive layer 31 wetted with water. As a result, the printed layer 2 can be transferred onto the glass plate 1 as shown in FIG. 4(c). The paste layer 31 dissolves in water and disappears.

After the above-described transfer process, the printed layer 2 is heated by using a heating furnace or the like as shown in FIG. At that time, the coat layer 32 is also heated, and the coat layer 32 is burned out by this heating.

Through the series of steps described above, the stove top plate A is manufactured. According to the manufacturing method, the following effects are obtained.

First, in the stovetop top plate A manufactured by the manufacturing method described above, when viewed from above, the colored pattern printed layer 20 with the white printed layer 21 as a background can be seen through the glass plate 1. . Since the colored pattern printed layer 20 displays a plurality of dot-like patterns F1 as described above, the overall appearance of the stovetop top plate A can be improved. In addition, since the color pattern printed layer 20 also displays the stove-related information F2 and F3, it is not necessary to attach a separate label to the glass plate 1 for displaying the stove-related information F2 and F3.

Since the printed layer 2 is provided on the back surface 1a of the glass plate 1, there is no fear that the printed layer 2 will be peeled off or damaged by contact with an article or the like. The bottom layer of the printed layer 2 is a dark-colored printed layer 22. This dark-colored printed layer 22, for example, as indicated by the arrow Na in FIG. When it wraps around, it plays a role in preventing the spilled liquid from looking dirty from above the glass plate 1.例文帳に追加The white-based printed layer 21 plays a role of making the color of the colored pattern printed layer 20 look like the originally intended color.

In the manufacturing method described above, a method of transfer printing using a transfer sheet S is used as means for providing the printed layer 2 on the glass plate 1 . Therefore, when changing the pattern (color pattern) represented by the print layer 2, only the transfer sheet S should be changed. The transfer process itself and the printing process itself do not need to be changed. According to the above-described manufacturing method, compared with the conventional technology in which a printed layer is provided on a glass plate by screen printing, it is possible to easily and quickly change the pattern, and the productivity is good, and a wide variety of products and small quantities are available. Also suitable for production. Therefore, the manufacturing cost of the stove top plate A can be reduced.

On the other hand, when manufacturing many types of stoves B, a plurality of types of transfer sheets S are prepared, and the work of transferring the print layer 2 to the glass plate 1 is performed according to the manufacturing situation of the stoves B. It is only necessary to carry out the steps according to circumstances and complete the top plate A for the stove. Therefore, there is no need to keep a large number of stocks of stove top plates A of a plurality of types, and the economic burden can be further reduced.

The color pattern printed layer 20 of the transfer sheet S is an inkjet printed layer, but this inkjet printed layer can be provided easily and quickly using an inkjet printer, and the specific pattern can be arbitrarily selected. It is possible to change. Therefore, while the white printed layer 21 and the dark printed layer 22 of the transfer sheet S are common, by easily changing the pattern shown by the inkjet printed layer (color pattern printed layer 20), various designs for stoves can be obtained. It also becomes possible to manufacture the top plate A simply and quickly. Therefore, it is more suitable for high-mix low-volume production, and it is easy to change the manufacturing number of the stove B indicated by the stove-related information F2.

This additional transfer sheet Sa has a configuration in which a water-soluble glue layer 31a, a print layer 2A, a clear layer 29, and a coat layer 32a are laminated in this order on a backing paper 30a. The printed layer 2A displays the stove-related information F4 described above, and is an inkjet printed layer provided using an inkjet printer.

Next, the printed layer 2A and the clear layer 29 of the additional transfer sheet Sa are transferred to the standing surface 1b of the glass plate 1. As shown in FIG. As shown in FIG. 6(b), this transfer is performed by peeling off the backing paper 30a of the additional transfer sheet Sa, and contacting the standing surface 1b of the glass plate 1 with the adhesive layer 31a wetted with water. . As a result, the printed layer 2A can be transferred onto the glass plate 1 as shown in FIG. The glue layer 31a dissolves in water and disappears.
After that, the printed layer 2A, the clear layer 29, and the like are heated and baked onto the glass plate 1, as shown in FIG. At that time, the coat layer 32 is burned off. The printing layer 2A and the clear layer 29 are printed at the same time as the printing layer 2 on the back surface 1a of the glass plate 1 is printed.

Through the series of steps described above, the stove top plate Aa is manufactured. According to this manufacturing method, the printed layer 2A (additional printed layer) provided on the standing surface 1b of the glass plate 1 can be used to appropriately display the stove-related information F4.
