Description

本発明はガラス溶融物からガラス板を成型し、次いで、前記ガラス板の端部において浅いファセット（小面：ガラス板の主面としての上面を補完する面）を研削することによるか、もし必要ならセラミック化を施し、ファセット付ガラス・セラミック板とするか、あるいは予めセラミック化されたガラス・セラミック板の端部において浅いファセットを研削することによって、幅広にファセットを形成されたガラス／ガラス・セラミック板の製造方法に関する。   The present invention is by molding a glass plate from a glass melt and then grinding shallow facets (small surface: a surface that complements the upper surface as the main surface of the glass plate) at the end of the glass plate or if necessary Glass / glass ceramic with wide facets formed by ceramizing and making faceted glass-ceramic plates or grinding shallow facets at the edges of pre-ceramic glass-ceramic plates The present invention relates to a method for manufacturing a plate.

本発明はさらに、前記ファセットの刻まれたガラス/ガラス・セラミック板自体にも関する。   The invention further relates to the faceted glass / glass ceramic plate itself.

今日では、ガラスまたはガラス・セラミック板は調理ホブの据えつけ部分とされており、電熱式ホブの場合にはガラス・セラミック板が主調理板として用いられ、ガス加熱式ホブの場合にはガラス板が主調理板として用いられている。   Today, glass or glass-ceramic plates are used as installation parts for cooking hobs, and glass-ceramic plates are used as main cooking plates in the case of electric heating hobs, and glass plates in the case of gas-heating hobbs. Is used as the main cooking plate.

厨房家具自体等の厨房調度品の一部としてのガラス/ガラス・セラミック調理板は特に美観に関わる流行やデザインの動向に左右される。そのため、今日では、縁が薄く形成されるように縁部分が狭められた特別な縁デザインによるガラス・セラミック調理板、好ましくは浅い表面ファセットを周囲全体に有するガラス／ガラス・セラミック調理板に対する需要が高まっている。   Glass / glass / ceramic cooking plates as part of kitchen furniture such as kitchen furniture itself are particularly affected by fashion trends and design trends. Therefore, today there is a need for a glass / ceramic cooking plate with a special edge design that has a narrowed edge so that the edge is formed thin, preferably a glass / glass ceramic cooking plate with a shallow surface facet all around. It is growing.

ＤＥ１９６４９７６７Ａ１には、縁部分にファセットが形成されたガラス・セラミック調理板が既に開示されている。しかしながら、浅いファセットをガラスまたはガラス・セラミック板中へ研削する際、開始時の前記板の厚さ及び残存厚、さらに最小ファセット角によっても前記浅いファセット幅に制限が生じる。
かかる理由から、前記ドイツ特許明細書に記載された浅いファセットの場合、約３０ｍｍに制限された幅しかもたない。 DE19649767A1 already discloses a glass-ceramic cooking plate with facets formed at the edges. However, when grinding a shallow facet into a glass or glass-ceramic plate, the shallow facet width is also limited by the thickness and residual thickness of the plate at the start and the minimum facet angle.
For this reason, the shallow facets described in the German patent specification have a width limited to about 30 mm.

しかしながら、より幅広なファセットに対する需要に対応するためには、現行の製造方法では、強度上の必要性からガラス・セラミック板を一定の残存厚に保持しなければならないため、前記板全体の厚さを増加させることが必要となる。さらに、こぼれた液体や溢れた食品がファセットを越えて厨房床面あるいは作業面上へ流れ出ることを防止することも必要である。   However, in order to meet the demand for wider facets, the current manufacturing method requires the glass / ceramic plate to be kept at a certain residual thickness due to the need for strength. Need to be increased. In addition, it is necessary to prevent spilled liquid and overflowing food from flowing over the facet onto the kitchen floor or work surface.

本発明は、序文において述べたように、この種のタイプのガラス／ガラス・セラミック調理板の標準的厚さを増加させることを必要とせずに、極めて広い表面ファセットが設けられ、かつ溢出を防止できるガラス／ガラス・セラミック板の製造を可能とする方法を提供する上記目的に基づいて為されたものである。   The present invention, as mentioned in the introduction, provides an extremely wide surface facet and prevents overflow without the need to increase the standard thickness of this type of glass / glass ceramic cooking plate It was made on the basis of the above object to provide a method enabling the production of a glass / glass-ceramic plate that can be produced.

上記目的は、本発明に従ったガラス／ガラス・セラミック板の製造方法、すなわちガラス溶融物からガラス板を成型し、次いで、前記ガラス板の端部において浅いファセットを研削することによるか、必要ならこれらをセラミック化し、ファセット付ガラス・セラミック板となすか、あるいは予めセラミック化されたガラス・セラミック板の端部において浅いファセットを研削することから構成される幅広にファセット形成されたガラス／ガラス・セラミック板の製造方法において、前記ガラス板を成型する第一段階において、前記板の少なくとも一端部に当たる素材に隆起構造を形成し、及び第二段階において、３０ｍｍないし７０ｍｍの幅をもち、かつファセットの内側縁部に前記板の上面よりも高く形成されたフランク（縦になった側面）を有する幅広なファセットが前記板の相当端部に形成されるよう、前記素材の隆起構造を利用して研削することによって達成される。   The above object is achieved by a method for producing a glass / glass ceramic plate according to the invention, i.e. by molding a glass plate from a glass melt and then grinding shallow facets at the edges of said glass plate, if necessary. Widely faceted glass / glass ceramic consisting of ceramicizing them into glass ceramic plates with facets, or grinding shallow facets at the edges of preceramic glass ceramic plates In the plate manufacturing method, in the first step of molding the glass plate, a raised structure is formed on the material that hits at least one end of the plate, and in the second step, it has a width of 30 mm to 70 mm and is inside the facet. Flank formed on the edge higher than the top surface of the plate ) Is wide facet having to be formed on the corresponding end of the plate is achieved by grinding using a raised structure of the material.

本発明は、ガラス／ガラス・セラミック板の全体の厚さを増加させることなく、極めて幅広なファセットが形成されたガラス／ガラス・セラミック板を製造することを可能とする。さらに、ファセットの内側上の隆起したフランクによって所望の溢出防止を行うことが可能である。   The present invention makes it possible to produce a glass / glass ceramic plate with very wide facets formed without increasing the overall thickness of the glass / glass ceramic plate. Furthermore, it is possible to provide the desired overflow prevention with raised flank on the inside of the facet.

従って、本発明はさらに、ガラス／ガラス・セラミック板の少なくとも一方の面上に、幅が３０ｍｍないし７０ｍｍの範囲内であり及び上端が内側において前記板面へさがっているフランクを有する幅広な面ファセットが形成されたガラス／ガラス・セラミック板にも関する。   Accordingly, the present invention further provides a wide facet having at least one flank on at least one surface of a glass / glass ceramic plate having a width in the range of 30 mm to 70 mm and having an upper end inwardly extending to the plate surface. It also relates to a glass / glass-ceramic plate on which is formed.

前記素材の隆起の高く形成された構造は、好ましくは前記ガラス板の対応する成型工程の一部としてロール加工あるいはプレス加工によって形成することが可能である。
前記ガラス板のロール作業中に成型できること自体は周知であるが、適当な場合には、かかる成型も同様にセラミック化されてガラス・セラミック板が形成される。 The structure of the material with high bulges can be formed by roll processing or pressing, preferably as part of the corresponding molding process of the glass plate.
Although it is well known that it can be molded during the roll operation of the glass plate, if appropriate, such molding is also ceramicized to form a glass-ceramic plate.

ところで、ＤＥ１９９０６９１１Ｃ１には、操作用機器を保護するため、段状構造が調理区域と操作パネルとの間の青色ガラスの高さに含まれるようにロール加工された操作パネルと一体の調理板用ガラス・セラミック板が開示されている。また、ＤＥ１９６１００７３Ａ１にも段状化されたガラス・セラミック調理板が開示されている。   By the way, DE19906911C1 discloses a glass for a cooking plate integrated with an operation panel that is rolled so that the stepped structure is included in the height of the blue glass between the cooking area and the operation panel in order to protect the operation equipment. A ceramic plate is disclosed. DE 19610073A1 also discloses a stepped glass / ceramic cooking plate.

ＤＥ１９９０６９６３Ｃ１には、スタッド間にウェブが約０．２ｍｍの間隔で配された、散乱光成分を増大させるためのスタッド様の下面構造をもつガラス・セラミック板が記載されている。   DE 19906963C1 describes a glass-ceramic plate with a stud-like underside structure for increasing the scattered light component, in which webs are arranged between the studs with a spacing of about 0.2 mm.

ＤＥ１９６３３７０６Ａ１においては、蓄電器センサスイッチに対するスタッドの影響を減ずるため、無スタッド型の縁を有するガラス・セラミック調理ホブが開示されている。   In DE 19633706 A1, a glass-ceramic cooking hob with a studless edge is disclosed in order to reduce the influence of the stud on the capacitor sensor switch.

しかしながら、これらの引例によっては、隆起構造がファセット研削に先立って形成された素材を厚くする結果として起こるガラス／ガラス・セラミック板の成型工程中のファセットから溢出を防止する縁部を備えた、幅広にファセット形成されたガラス／ガラス・セラミック板の製造に関しては何らの示唆も当業者に対して与えられていない。   However, in some of these references, a wide structure with edges that prevent spillage from facets during the glass / glass-ceramic plate molding process that occurs as a result of the raised structure thickening the material formed prior to facet grinding. No suggestions are given to the person skilled in the art regarding the production of faceted glass / glass ceramic plates.

本発明の構成は、従属請求項において特徴づけられるとともに、添付図面中に示した例示的実施態様の記載から明らかにされる。   The construction of the invention is characterized in the dependent claims and is made clear from the description of the exemplary embodiments shown in the accompanying drawings.

図１Ａないし図１Ｆは、板端部から２つの異なる間隔でロール方向へロール形成された例示的形状２ａ、２ｂ、２ｃ及び２’ａ、２’ｂ、２’ｃで示される隆起構造を有するガラス／ガラス・セラミック板１をそれぞれ示す図である。この種のガラス／ガラス・セラミック板は一般的にホブ用の調理板として用いられる。板厚は一般的には４ｍｍである。これら板は、公知の方法によって、後に個々の板へと分離されるロール形の連続ガラスリボンから製造される。原則として、これらの板は個々にプレス加工することも可能である。これらガラス板は、最終製品にも相当するが、通常の方法でセラミック化されるガラス・セラミック板用の青色ガラスとして知られる前駆ガラスにも相当するものである。   1A to 1F have raised structures shown as exemplary shapes 2a, 2b, 2c and 2'a, 2'b, 2'c rolled in the roll direction at two different intervals from the plate edge. It is a figure which shows the glass / glass and ceramic board 1, respectively. This type of glass / glass ceramic plate is generally used as a cooking plate for hobbing. The plate thickness is generally 4 mm. These plates are produced from roll-shaped continuous glass ribbons which are later separated into individual plates by known methods. In principle, these plates can also be pressed individually. These glass plates correspond to the final product, but also to the precursor glass known as blue glass for glass-ceramic plates that are ceramicized by conventional methods.

前記隆起構造は、同じくそれ自体公知である方法、例えば先に引用したＤＥ１９９０６９１１Ｃ１に記載された方法によって、ロール中の実質的に直角に折り曲げられるか、斜めか、あるいは凹状に湾曲された転移部による対応工程を経て形成される。但し、原則として、これらの隆起構造はプレス加工によっても形成可能である。   The raised structure is formed by a transition that is also bent at a substantially right angle in the roll, diagonally or concavely, in a manner also known per se, for example as described in DE 199069911 C1 cited above. It is formed through a corresponding process. However, in principle, these raised structures can also be formed by pressing.

図１Ａ及び図１Ｂに薄板形状で示した隆起構造２ａ及び２’ａには実質的に直角の転移部がある一方、図１Ｃ及び図１Ｄの隆起構造２ｂ及び２’ｂは傾斜路様の形状を呈し、図１Ｅ及び図１Ｆの隆起構造２ｃ及び２’ｃは凸面状形状を呈している。構造２を端部からより離れるように位置させればさせるほど、その後ファセットをより浅くかつ幅広に形成することが可能となる。隆起構造の大きさは製造対象であるファセットに必要とされる材料の量に従って選択される。   The raised structures 2a and 2'a shown in thin plate form in FIGS. 1A and 1B have substantially perpendicular transitions, while the raised structures 2b and 2'b in FIGS. 1C and 1D are ramp-like shapes. And the raised structures 2c and 2'c of FIGS. 1E and 1F have a convex shape. The more the structure 2 is located farther from the end, the later the facet can be formed shallower and wider. The size of the raised structure is selected according to the amount of material required for the facet to be manufactured.

図１に例示的に図示され、かつロール加工あるいはプレス加工された隆起構造が設けられた板は、本発明に係る方法の第一工程において形成される中間生成物を表す。次いで第二工程において、公知の方法を用いてファセット３が隆起構造中及び板縁部中に研削形成される。前記研削は、図２に示すように、隆起構造の残余部分３ａが溢出を防止するため適切に配置されて残存するように行われる。図２Ａは一端部のみにファセットが形成された板を示す図であり、図２Ｂは２つの対向する端部にファセットが形成された板を示す図である。ガラス板及び隆起構造がプレス加工によって作られる場合は、前記周囲全体にファセット形成を行うことも可能である。従って、図３Ａ及び図３Ｂは図１に従って端部から異なる間隔で一端部のみに形成された隆起構造２、２’の平面図であり、これらは図２Ａに示すファセット形成された板とされるものであり、一方、図３Ｃ及び図３Ｄは図１に従って同様に端部から異なる間隔で２つの対向する端部に形成された隆起構造２、２’を示す図であり、これらは図２Ｂに示すファセット形成された板とされるものである。   The plate illustrated in FIG. 1 and provided with a rolled or pressed raised structure represents the intermediate product formed in the first step of the method according to the invention. Then, in a second step, the facets 3 are ground and formed in the raised structure and in the plate edge using known methods. As shown in FIG. 2, the grinding is performed so that the remaining portion 3 a of the raised structure is appropriately disposed and remains in order to prevent overflow. 2A is a diagram showing a plate having facets formed only at one end, and FIG. 2B is a diagram showing a plate having facets formed at two opposing ends. When the glass plate and the raised structure are made by press working, it is possible to facet the entire periphery. Accordingly, FIGS. 3A and 3B are plan views of raised structures 2, 2 ′ formed only at one end at different intervals from the end according to FIG. 1, and these are the faceted plates shown in FIG. 2A. 3C and 3D are diagrams showing raised structures 2, 2 'formed at two opposite ends, similarly at different distances from the ends according to FIG. 1, and these are shown in FIG. 2B. The facet-formed plate is shown.

ファセットの幅は７０ｍｍまで可能である。外側の先細に形成された端部におけるガラスの残存厚は少なくとも２．５ｍｍ必要であり、ファセットの内側端部における隆起３ａは約２ｍｍである。   The facet width can be up to 70 mm. The remaining thickness of the glass at the outer tapered end must be at least 2.5 mm and the ridge 3a at the inner end of the facet is about 2 mm.

超幅広のファセットはパネルとして形成する選択肢を与える利点をもち、これにより調理板あるいは付随するホブの操作に必要とされる作動及び表示機器を幅広な傾斜端部へ取り付けることが可能である。   The ultra-wide facet has the advantage of giving the option of forming as a panel, so that the actuation and display equipment required for operation of the cooking plate or associated hob can be attached to the wide inclined end.

ファセット形成されたガラス・セラミック板を製造する場合、青色ガラス板へファセット形成を行った上で、該青色ガラスを公知の熱処理方法によってガラス・セラミック板へ変換させることが可能である。しかしながら、ファセット形成を未だ行っていない青色ガラスをガラス・セラミックへと変換してから該青色ガラス中へファセットを研削形成することも可能である。   When manufacturing a faceted glass / ceramic plate, it is possible to convert the blue glass into a glass / ceramic plate by a known heat treatment method after faceting the blue glass plate. However, it is also possible to convert the blue glass that has not yet undergone faceting into glass-ceramic and then grind and form the facets into the blue glass.

特に素材に隆起（厚くなった部分）が設けられるように形状化されたガラス及び／またはガラス・セラミック板の極めて概略化した断面図である。これら隆起は総じて隆起構造と呼ぶことができ、好ましくは前記板の一端部に配され、それらの形状は図１Ａないし図１Ｆに示すような種々形状に適合させることが可能である。FIG. 2 is a highly schematic cross-sectional view of a glass and / or glass-ceramic plate shaped in particular so that the material is provided with ridges (thickened parts). These ridges can be collectively referred to as a ridge structure, and are preferably disposed at one end of the plate, and their shapes can be adapted to various shapes as shown in FIGS. 1A to 1F. 図１に対応する断面図であり、図１に示した開始時の板を用いて幅広にファセット形成が行われたガラスあるいはガラス・セラミック板を示す図である。図２Ａは一方の端部のみにファセットが形成された板を示す図であり、図２Ｂは２つの対向する端部へファセットが形成された板を示す図である。It is sectional drawing corresponding to FIG. 1, and is a figure which shows the glass or glass-ceramic board by which facet formation was performed widely using the board | plate at the time of the start shown in FIG. 2A is a diagram showing a plate with facets formed only on one end, and FIG. 2B is a diagram showing a plate with facets formed on two opposing ends. 図３Ａ及び図３Ｂは、一方の側の端部にぴったりと、あるいは一方の側の端部から所定間隔をおいてロール形成された図１に従った隆起構造を有する板をそれぞれ示す平面図であり、図３Ｃ及び図３Ｄには双方の側の端部にぴったり、あるいは一方の側の端部から所定間隔をおいてロール形成された隆起構造を有する板をそれぞれ示す平面図である。FIGS. 3A and 3B are plan views respectively showing a plate having a raised structure according to FIG. 1 that is formed on a roll tightly at an end on one side or at a predetermined interval from the end on one side. FIG. 3C and FIG. 3D are plan views each showing a plate having a raised structure that is tightly formed on the ends on both sides or is formed at a predetermined interval from the ends on one side.
