Description

この発明は、外壁パネルの外壁面材等となる窯業系、天然石系、木質系、樹脂系等の面状建材の裏面等に、パネルフレームへの取付穴等となる穴の加工や切断加工等を行う面状建材加工装置に関する。   This invention is a process for cutting or cutting holes for mounting holes on panel frames, etc. on the back surface of planar building materials such as ceramics, natural stones, woods, and resins that serve as outer wall materials for outer wall panels, etc. The present invention relates to a planar building material processing apparatus.

戸建住宅や、集合住宅、事務所ビル等の建物の外壁パネルとして、窯業系の外壁面材が用いられる。この外壁面材は、通常、屋外面となる化粧面から、裏側の鋼製のパネルフレームにビスを打つことで取付けるか、またはサネ加工により金物で取付ける。サネ加工による場合は、現場施工のみになり、生産性が悪く品質管理が難しいため、工業化生産の面からは、前者の方法が好ましい。しかし、化粧面からビスを打った構造では、ビス打ち箇所の痕跡を隠す再塗装（タッチアップ）等の化粧直し処理が必要となる。この化粧直しの処理は、現場施工となって手間がかかる上、品質管理が難しく、工業化生産を阻害する要因となる。
このような後処理が不要な外壁面材の取付構造として、外壁面材の裏面に掛け金物を係合させる取付穴を設け、この取付穴を、掛け金物の頭部を挿入させる挿入部と、この挿入部に続く蟻溝状のスライド部とでなる形状としたものが提案されている（例えば、特許文献１）。これによれば、パネルフレームに設けられた各掛け金物に、外壁面材の取付穴が挿入部で挿入されるように外壁面材を配置し、掛け金物が取付穴のスライド部に係合するようにスライドさせることで、外壁面材の取付けが行え、従来の多数のビス穴の後処理が不要となる。 Ceramic outer wall materials are used as outer wall panels of detached houses, apartment houses, office buildings and the like. This outer wall surface material is usually attached by hitting a screw to a steel panel frame on the back side from a decorative surface serving as an outdoor surface, or is attached with a metal object by sane processing. In the case of sane processing, only the on-site construction is performed, and the productivity is poor and quality control is difficult. Therefore, the former method is preferable from the viewpoint of industrial production. However, in the structure in which a screw is struck from the decorative surface, a makeup retouching process such as repainting (touch-up) that hides the traces of the screwed part is required. This re-dressing process is an on-site construction and takes time and is difficult to control the quality, which impedes industrialized production.
As an attachment structure of the outer wall surface material that does not require such post-processing, an attachment hole for engaging the latch on the back surface of the outer wall surface material is provided, and this attachment hole is an insertion portion for inserting the head of the latch, The thing made into the shape which consists of a dovetail-shaped slide part following this insertion part is proposed (for example, patent document 1). According to this, the outer wall surface material is arranged so that the mounting hole of the outer wall surface material is inserted into the latch provided on the panel frame at the insertion portion, and the latch is engaged with the slide portion of the mounting hole. By sliding in such a manner, the outer wall surface material can be attached, and post-processing of a number of conventional screw holes becomes unnecessary.

このような引っ掛け構造の外壁面材の例を、図１１〜図１４と共に説明する。図１１に示すように、外壁面材７１の裏面に、パネルフレームの配列にピッチに応じて、取付穴７２が複数列（Ｌ１〜Ｌ３）に並べて設けられる。各取付穴７２は、図１２，図１３に拡大して示すように、掛け金物７３の拡径した頭部７３ａが挿入可能な円形の挿入部７２ａと、この挿入部７２ａに続いて形成されて掛け金物７３の軸部７３ｂのみが挿入可能な開口部幅のスライド部７２ｂとでなる。スライド部７２ｂは、穴底部が広がった蟻溝状に形成され、その広がった穴内空間に、掛け金物７３の頭部７３ａが進入する（図１３（Ｂ））。   An example of the outer wall surface material having such a hook structure will be described with reference to FIGS. As shown in FIG. 11, mounting holes 72 are provided on the back surface of the outer wall surface material 71 in a plurality of rows (L1 to L3) in accordance with the pitch of the arrangement of the panel frames. As shown in FIGS. 12 and 13 in an enlarged manner, each mounting hole 72 is formed following a circular insertion portion 72a into which the head portion 73a having a diameter of the latch 73 can be inserted, and the insertion portion 72a. Only the shaft portion 73b of the latch 73 has a slide portion 72b having an opening width that can be inserted. The slide part 72b is formed in a dovetail shape with the bottom of the hole widened, and the head 73a of the latch 73 enters the widened space in the hole (FIG. 13B).

図１４は、外壁パネル７０における外壁面材７１とパネルフレーム７４の関係を示す。鋼製のパネルフレーム７４に、グラスウールボード等の断熱材７５と、ポリスチレンボード等の下地材７６を介して、掛け金物７３を取付ける。掛け金物７３は、ドリル付きタッピンねじ等からなり、下地材７６および断熱材７５を貫通してパネルフレーム７４にねじ込まれる。掛け金物７３は、拡径した頭部７３ａが皿形に形成されており、下地材７６の表面から一定高さだけ突出させておく。掛け金物７３は、図示の例では頭部７３ａが軸部７３ｂとは別体の部品で形成されているが、軸部７３ｂと一体であってもよい。このように掛け金物７３を取付けたパネルフレーム７４上に、前述のように外壁面材７１を、各取付穴７２の挿入部７２ａ（図１３）に掛け金物７３が挿入されるように配置し、掛け金物７３の頭部７３ａが取付穴７２のスライド部７２ｂに係合するように外壁面材７１をスライドさせることで、外壁面材７１の取付けが行える。このように、外壁面材７１は裏面で固定されるため、屋外面に貫通したビス穴が生じず、後処理が不要となる。   FIG. 14 shows the relationship between the outer wall surface material 71 and the panel frame 74 in the outer wall panel 70. A latch 73 is attached to a steel panel frame 74 via a heat insulating material 75 such as glass wool board and a base material 76 such as polystyrene board. The latch 73 includes a tapping screw with a drill or the like and penetrates the base material 76 and the heat insulating material 75 and is screwed into the panel frame 74. The latch 73 has a head 73 a having an enlarged diameter and is formed in a dish shape, and protrudes from the surface of the base material 76 by a certain height. In the illustrated example, the head 73a is formed as a separate component from the shaft portion 73b, but the latch 73 may be integrated with the shaft portion 73b. As described above, the outer wall surface material 71 is arranged on the panel frame 74 to which the latch 73 is attached in this manner so that the latch 73 is inserted into the insertion portion 72a (FIG. 13) of each attachment hole 72. The outer wall surface material 71 can be attached by sliding the outer wall surface material 71 so that the head portion 73 a of the latch 73 is engaged with the slide portion 72 b of the attachment hole 72. Thus, since the outer wall surface material 71 is fixed on the back surface, a screw hole penetrating the outdoor surface does not occur, and post-processing is not required.

外壁面材７１への取付穴７２の加工は、図１５（Ａ）のようにルータ７７を用いて行われる。ルータ７７は、穴加工用の回転工具７８を下向きに有するものである。外壁面材７１は、加工テーブル７９上に表裏反転させて配置し、穴加工を行う。ルータ７７には、複数の回転工具７８を持つ多軸ルータが用いられ、また数値制御式のものが用いられる（例えば、特許文献２）。   The processing of the mounting hole 72 in the outer wall surface material 71 is performed using a router 77 as shown in FIG. The router 77 has a rotary tool 78 for drilling downward. The outer wall surface material 71 is disposed on the processing table 79 so as to be turned upside down and drilled. As the router 77, a multi-axis router having a plurality of rotary tools 78 is used, and a numerical control type is used (for example, Patent Document 2).

特開２００９−２４９８９９号公報JP 2009-249899 A 特開平１１−３２０５４９号公報JP-A-11-320549

図１５に示すように、外壁面材７１は、加工テーブル７９上に表裏反転させて配置し、穴加工を行う。ルータ７７は数値制御式のものであり、取付穴７２の底面加工時には、加工テーブル７９の上面を基準として、プログラムで定められ高さに位置するように、精度良く制御される。
しかし、建材である外壁面材７１は、一般的に厚みの誤差が１０％程度まで許容されており、その範囲で種々バラツキの板厚のものが用いられる。また、外壁面材７１の各部によって板厚にばらつきがある。そのため、ルータ７７の高さを加工テーブル７９の上面を基準として制御した場合、取付穴７２の深さＤ０や、取付穴７２のスライド部７２ｂにおける奥広がり部分から面材裏面までの深さＤａが、外壁面材７１の板厚のバラツキ分ａだけ、ばらつく。外壁面材７１の反り等による裏面位置の不陸によっても、上記深さＤａ，Ｄ０のばらつきが生じる。 As shown in FIG. 15, the outer wall surface material 71 is disposed on the processing table 79 so as to be turned upside down and performs hole processing. The router 77 is of a numerical control type, and when the bottom surface of the mounting hole 72 is processed, the router 77 is controlled with high accuracy so as to be positioned at a height determined by a program with reference to the upper surface of the processing table 79.
However, the outer wall surface material 71 which is a building material is generally allowed to have a thickness error of about 10%, and various thicknesses are used within this range. In addition, the thickness of each part of the outer wall surface material 71 varies. Therefore, when the height of the router 77 is controlled on the basis of the upper surface of the processing table 79, the depth D0 of the mounting hole 72 and the depth Da from the deepened portion in the slide portion 72b of the mounting hole 72 to the back surface of the face material are determined. The outer wall surface material 71 varies by the variation a of the plate thickness. Variations in the depths Da and D0 also occur due to unevenness of the back surface position due to warpage of the outer wall surface 71 or the like.

建材系では、一般的に誤差の許容範囲が大きいが、図１４のように取付穴７２に掛け金物７３を係合させる構造では、取付穴７２の上記深さＤａ，Ｄ０にばらつきがあると、掛け金物７３による外壁面材７１のフレーム７４への固定の緩みや、取付不能につながる。例えば、奥広がり部分までの深さＤａが浅過ぎると、掛け金物７３の頭部７３ａと取付穴７２の奥広がり部分を構成する頭部接触面７２ｂａ（図１４）との間に隙間が生じて、外壁面材７１を安定して固定できなくなる。また、上記深さＤａが深過ぎると、取付穴７２の挿入部７２ａに入った頭部７３ａが、頭部接触面７２ｂａよりも浅い位置となってスライド部７２ｂへ移動できなくなる。そのため、図１４のような優れた取付構造が提案されているが、従来の加工技術では実施することができなかった。
また、外壁面材７１を表裏反転させて加工するため、外壁パネルの生産ラインで、外壁面材７１を表裏反転させる工程、および再度表裏反転させて元に戻す工程が必要となり、外壁パネルの生産ラインが複雑になるという問題があった。 In the building material system, generally, the tolerance of error is large, but in the structure in which the latch 73 is engaged with the mounting hole 72 as shown in FIG. This leads to loose fixing of the outer wall surface 71 to the frame 74 by the latch 73 and inability to attach. For example, if the depth Da to the deepened portion is too shallow, a gap is generated between the head 73a of the latch 73 and the head contact surface 72ba (FIG. 14) constituting the deepened portion of the mounting hole 72. The outer wall material 71 cannot be stably fixed. If the depth Da is too deep, the head 73a that has entered the insertion portion 72a of the mounting hole 72 becomes shallower than the head contact surface 72ba and cannot move to the slide portion 72b. For this reason, an excellent mounting structure as shown in FIG. 14 has been proposed, but it could not be implemented by the conventional processing technique.
In addition, in order to process the outer wall material 71 by reversing the front and back, it is necessary to perform a process of reversing the outer wall surface material 71 on the outer wall panel production line and a process of reversing the front and back again and returning to the original state. There was a problem that the line was complicated.

この発明の目的は、建材となる面材に対して、板厚等のばらつきに係わらず、裏面を精度良く加工することができる面状建材加工装置を提供することである。   An object of the present invention is to provide a planar building material processing apparatus that can accurately process the back surface of a surface material to be a building material regardless of variations in sheet thickness or the like.

この発明の面状建材加工装置は、外壁パネルの外壁面材である面材の裏面に、穴底部が広がった蟻溝状の部分を有する取付穴を複数個並べて切削加工する装置であって、上下に貫通したカッタ挿通窓を有し前記面材を載せる加工テーブルと、この加工テーブル上の面材を上面から前記加工テーブル上に押し付ける上面押付け機構と、前記カッタ挿通窓に挿通可能な回転工具を上下方向に延びる主軸の上端に有し前記主軸を回転駆動して前記面材の下面を加工する主軸ヘッドと、この主軸ヘッドを直交３軸方向に移動させる主軸移動機構とを備える。 The planar building material processing apparatus of the present invention is an apparatus that performs cutting by arranging a plurality of mounting holes having dovetail-shaped portions with the hole bottoms widened on the back surface of the surface material that is the outer wall surface material of the outer wall panel , A processing table having a cutter insertion window penetrating vertically and placing the face material thereon, an upper surface pressing mechanism for pressing the surface material on the processing table onto the processing table from the upper surface, and a rotary tool that can be inserted into the cutter insertion window and a spindle head that the spindle has at the upper end of the main shaft extending vertically driven to rotate for processing the lower surface of the surface material, Ru and a spindle moving mechanism for moving the spindle head in three orthogonal directions.

この構成によると、面材を加工テーブル上に押し付け、その押し付けられた裏面側から回転工具による加工が行われる。そのため、被加工物である面材の加工基準面と、加工装置の基準面を合わせる形態で面材を配置し、かつ押し付けて密着させ、この加工基準面と装置基準面が密着した状態で加工が行われることになる。そのため、面材に板厚のばらつきや反り等が生じていても、この面材の加工基準面に対して精度良く加工することができ、穴加工においては、加工基準面に対する深さを高精度に加工することができる。前記面材は外壁パネルの外壁面材であるが、裏面に取付用の穴加工を行うにつき、反転させる必要がないため、外壁パネルの生産ラインの簡素化にもつながる。 According to this configuration, the face material is pressed onto the processing table, and processing with the rotary tool is performed from the pressed back side. Therefore, the face material is placed in a form that matches the processing reference surface of the face material that is the workpiece and the reference surface of the processing equipment, and pressed to bring it into close contact, and the processing reference surface and the equipment reference surface are in close contact with each other. Will be done. For this reason, even if the thickness of the face material varies or warps, it can be processed with high accuracy with respect to the processing reference surface of this face material. Can be processed. The face material is an outer wall surface material of the outer wall panel, but it is not necessary to reverse the holes when mounting holes on the back surface, so that the production line of the outer wall panel can be simplified.

前記主軸ヘッドは１列に並べて可動ベッドに複数台設置し、前記主軸移動機構は、前記可動ベッドを移動させることで前記主軸ヘッドを移動させるものとする。このように可動ベッドに主軸ヘッドを複数設けた場合、面材に対して複数箇所に同じ形状の加工を同時に行えて、加工時間が短縮される。外壁パネルの外壁面材では、取付穴を、パネルフレームに沿って複数並べて設けるが、このような１列に並ぶ複数箇所の同時加工が効率的に行える。
前記上面押付け機構は、前記主軸ヘッドのび方向に延びる昇降枠を、両端で昇降ガイドを介して昇降自在に支持し、前記昇降枠に主軸ヘッド並び方向に沿って複数の個別押し付け機構を設けた構成であっても良く、前記外壁面材は、窯業系面材、天然石系面材、または樹脂系面材であっても良い。 Prior Symbol spindle head arranged in a row placed multiple to the movable bed, the spindle moving mechanism, and for moving said spindle head by moving said movable bed. When a plurality of spindle heads are provided on the movable bed in this way, the same shape can be simultaneously processed in a plurality of locations on the face material, and the processing time is shortened. In the outer wall surface material of the outer wall panel, the mounting hole, multiple side by side provided along the panel frames, simultaneous machining of a plurality of locations arranged in such a row is Ru performed efficiently.
The upper surface pressing mechanism is configured to support an elevating frame extending in the extending direction of the spindle head so that the elevating frame can be raised and lowered at both ends via an elevating guide, and a plurality of individual pressing mechanisms are provided on the elevating frame along the alignment direction of the spindle heads. The outer wall surface material may be a ceramic surface material, a natural stone surface material, or a resin surface material.

このように複数の主軸ヘッドを設ける場合に、前記加工テーブルに対して、前記主軸ヘッドの並び方向と直交する方向に前記面材の搬入および搬出を行うと共に、前記加工テーブル上で前記面材を移動させる搬入搬出機構を設け、この搬入搬出機構に、前記加工テーブル上の面材の搬入方向の位置決めを行う面材搬入方向位置決め機構部、および前記搬入方向と直交する方向の位置決めを行う面材直交方向位置決め機構部を設けても良い。
上記搬入搬出機構を設け、面材搬入方向位置決め機構部、および面材直交方向位置決め機構部を設けた場合、面材の搬入搬出が効率的に行え、また面材の加工テーブルに対する直交２軸方向の位置決めが精度良く行える。そのため、面材の加工基準面に対する深さだけでなく、加工基準面に沿う方向の寸法についても精度良く加工することができる。 When a plurality of spindle heads are provided in this way, the face material is carried in and out of the machining table in a direction perpendicular to the direction in which the spindle heads are arranged, and the face material is placed on the machining table. A loading / unloading mechanism to be moved is provided, and in this loading / unloading mechanism, a surface material loading direction positioning mechanism for positioning the surface material on the processing table in the loading direction, and a surface material for positioning in a direction orthogonal to the loading direction An orthogonal direction positioning mechanism may be provided.
When the loading / unloading mechanism is provided and the face material loading direction positioning mechanism part and the face material orthogonal direction positioning mechanism part are provided, the loading and unloading of the face material can be performed efficiently, and the two orthogonal directions of the face material with respect to the processing table Can be accurately positioned. Therefore, not only the depth of the face material with respect to the processing reference surface, but also the dimension in the direction along the processing reference surface can be processed with high accuracy.

前記面材搬入方向位置決め機構部は、それぞれ前記面材の搬入側の端面を当接させる基準面を有しこの基準面に当接した面材の端部を把持する複数のチャックと、これら複数のチャックを前記主軸ヘッドの並び方向に並べて設置したチャック取付台と、このチャック取付台を前記面材の搬入方向に進退させるチャック進退機構と、前記面材を前記複数のチャックの基準面に対向して移動させて前記基準面に押し付ける面材押し込み機構とでなるものとしても良い。
この構成の場合、面材を上記チャックで把持して進退させるため、面材の移動が、滑り等を生じることなく確実に行える。このチャックに面材の搬入側の端面を当接させる基準面を設け、面材押し込み機構で面材をチャックの基準面に押し付けるため、面材の平面方向の移動や位置決めが、より精度良く行える。 The face material carry-in direction positioning mechanism section has a reference surface that abuts the end face on the carry-in side of the face material, and a plurality of chucks that grip the end portions of the face material in contact with the reference surface, The chuck mounting base in which the chuck heads are arranged in the alignment direction of the spindle head, a chuck advancing / retreating mechanism for moving the chuck mounting base back and forth in the loading direction of the face material, and the face material facing the reference surfaces of the plurality of chucks It is good also as what consists of a face material pushing mechanism which is moved and pressed against the above-mentioned reference plane.
In this configuration, since the face material is held by the chuck and moved forward and backward, the face material can be reliably moved without causing a slip or the like. This chuck is provided with a reference surface that abuts the end face of the face material on the carry-in side, and the face material is pressed against the reference surface of the chuck by the face material pushing mechanism, so that the movement and positioning of the face material in the planar direction can be performed with higher accuracy. .

この発明において、前記主軸ヘッドに、前記回転工具の近傍で工具先端側へ圧縮空気を吹き付けるノズルを設けても良い。
穴加工の場合、工具上に切削粉塵等が溜まり易いが、圧縮空気を吹き付けることにより、切削粉塵を外部に強制飛散させ、集塵回収することで、切削粉塵の残留量を大幅に低減させることができ、残留粉塵による加工効率や加工品質の低を回避することができる。 In this invention, you may provide the nozzle which blows compressed air to the tool front end side in the vicinity of the said rotary tool in the said spindle head.
In the case of drilling, cutting dust etc. tends to accumulate on the tool, but by blowing compressed air, cutting dust is forcibly scattered to the outside, and dust collection is collected to greatly reduce the residual amount of cutting dust. Therefore, it is possible to avoid low processing efficiency and processing quality due to residual dust.

なお、被加工物である面材Ｗは、例えば図１１〜図１４に示した外壁パネル５０の外壁面材７１となる板材であり、窯業系面材、大理石や御影石などの天然石系面材、木材やコンクリートパネル等と呼ばれる合板等の木質系面材、樹脂系面材等である。また、上記各材質の面材Ｗは、例えば表面に塗装や凹凸模様等の化粧が施されたものであっても良い。 また、この面状建材加工装置は、数値制御装置（図示せず）を備えていて、加工プログラムに従って次の各動作を行う。   In addition, the face material W which is a to-be-processed object is a board | plate material used as the outer wall surface material 71 of the outer wall panel 50 shown in FIGS. 11-14, for example, ceramic-based face materials, natural stone type face materials, such as marble and granite, These are wood-based face materials such as plywood called wood and concrete panels, and resin-based face materials. Further, the face material W made of each of the above materials may be, for example, a surface with a makeup such as painting or an uneven pattern. Moreover, this planar building material processing apparatus is provided with the numerical control apparatus (not shown), and performs each following operation | movement according to a processing program.

次に、上記構成の動作を説明する。面材Ｗは、搬入コンベヤ７によって加工テーブル２の付近まで搬入される。このとき、図８（Ａ）のように、各チャック５２はチッャク取付台５１と共に、チャック５２の基準面Ｓが、定められた位置に来るまで、加工テーブル２上に進出して待機している。このときチャック５２は開き状態とする。搬入コンベヤ７上の面材Ｗは、面材押し込み機構５４によって、同図のようにチャック５２の基準面Ｓに押し付ける。この押し付けによって、面材搬入方向（Ｙ軸方向）位置決めが成される。この押し付けの後、面材押し込み機構５４による押し付けを解除し、図４の直交方向押し付け機構６６により、面材Ｗを横位置決め定規６５に押し付ける。これにより面材Ｗは、面材搬入方向（Ｙ軸方向）およびその直交方向（Ｘ軸方向）に位置決め状態となる。この位置決め状態で、各チャック５２により面材Ｗを把持し、この把持の後、直交方向押し付け機構６６による押し付けを解除する。   Next, the operation of the above configuration will be described. The face material W is carried into the vicinity of the processing table 2 by the carry-in conveyor 7. At this time, as shown in FIG. 8 (A), each chuck 52, together with the chuck mounting base 51, advances and stands by on the processing table 2 until the reference surface S of the chuck 52 reaches a predetermined position. . At this time, the chuck 52 is opened. The face material W on the carry-in conveyor 7 is pressed against the reference surface S of the chuck 52 by the face material pushing mechanism 54 as shown in FIG. Positioning in the face material loading direction (Y-axis direction) is performed by this pressing. After this pressing, the pressing by the face material pressing mechanism 54 is released, and the face material W is pressed against the lateral positioning ruler 65 by the orthogonal direction pressing mechanism 66 of FIG. Thereby, the face material W will be in a positioning state in a face material carrying-in direction (Y-axis direction) and the orthogonal direction (X-axis direction). In this positioning state, each chuck 52 grips the face material W, and after this gripping, the pressing by the orthogonal direction pressing mechanism 66 is released.

このように、各チャック５２により面材Ｗを位置決め状態に把持した後、チャック取付台５１と共にチャック５２を移動させ、面材Ｗの加工しようとする部位が、加工テーブル２のカッタ挿通窓２２の所定位置に来るように、面材Ｗを移動させる。
ついで図８（Ｂ）のように、上面押付け機構３の昇降枠１７を下降位置とし、昇降枠１７に設置された各個別押し付け機構１９の押し板１９ｂによって、面材Ｗを上面から加工テーブル２の上面に押し付ける。個別押し付け機構１９は、面材Ｗの左右幅に応じて、面材Ｗの上方に位置するものだけを押し付け動作させる。
このように、面材Ｗを加工テーブル２に押し付けた状態で、各主軸ヘッド４の回転工具９により、面材Ｗの裏面に加工を施す。この加工は、例えば図１２に示したような取付穴７２の加工である。加工のための回転工具９の直交３軸方向の移動は、主軸移動機構５により可動ベッド１０を移動させることで行う。したがって、図１１のような各列Ｌ１〜Ｌ３の列内の複数の取付穴７２は、複数の主軸ヘッド４によって同時に、かつ同じ形状に加工される。加工を行う間は、図９のノズル６２から回転工具９に対して圧縮空気を吹きつける。 In this way, after gripping the face material W in the positioning state by each chuck 52, the chuck 52 is moved together with the chuck mounting base 51, and the part to be machined of the face material W becomes the cutter insertion window 22 of the machining table 2. The face material W is moved so as to come to a predetermined position.
Next, as shown in FIG. 8B, the elevating frame 17 of the upper surface pressing mechanism 3 is set at the lowered position, and the face material W is removed from the upper surface by the pressing plate 19b of each individual pressing mechanism 19 installed on the elevating frame 17. Press on the top of the. The individual pressing mechanism 19 presses only the one located above the face material W according to the left-right width of the face material W.
In this manner, the back surface of the face material W is processed by the rotary tool 9 of each spindle head 4 while the face material W is pressed against the processing table 2. This processing is, for example, processing of the attachment hole 72 as shown in FIG. The rotation tool 9 for machining is moved in the directions of the three orthogonal axes by moving the movable bed 10 by the spindle moving mechanism 5. Therefore, the plurality of mounting holes 72 in each of the rows L1 to L3 as shown in FIG. 11 are simultaneously processed into the same shape by the plurality of spindle heads 4. During the processing, compressed air is blown from the nozzle 62 in FIG.

上記のようにして一列（例えば図１１の列Ｌ１）の加工が終了すると、主軸ヘッド４を下方へ退避させ、上面押付け機構３の個別押し付け機構１９による面材Ｗの押し付けを解除した後、チャック取付台５１と共にチャック５２を移動させ、面材Ｗの加工しようとする列（例えば図１１の列Ｌ２）の部位が加工テーブル２のカッタ挿通窓２２の所定位置に来るように、面材Ｗを移動させる。この移動の後、上面押付け機構３の個別押し付け機構１９による押し付けを再度行い、主軸ヘッド４による面材Ｗの裏面の加工を上記と同様に行う。   When processing of one row (for example, row L1 in FIG. 11) is completed as described above, the spindle head 4 is retracted downward, the pressing of the face material W by the individual pressing mechanism 19 of the upper surface pressing mechanism 3 is released, and then the chuck The chuck 52 is moved together with the mounting base 51, and the face material W is moved so that the part of the row (for example, row L2 in FIG. 11) to be machined of the face material W comes to a predetermined position of the cutter insertion window 22 of the machining table 2. Move. After this movement, pressing by the individual pressing mechanism 19 of the upper surface pressing mechanism 3 is performed again, and the processing of the back surface of the face material W by the spindle head 4 is performed in the same manner as described above.

このようにして全ての列の加工が終了すると、主軸ヘッド４を下方へ退避させ、上面押付け機構３の個別押し付け機構１９による面材Ｗの押し付けを解除し、かつ昇降枠１７を上方退避位置へ上昇させる。また、チャック５２を図９の上方退避位置に上昇させる。この状態で、搬出機構部４４（図４）の払い出し機構４９におけるチェーン４９ａを回動させて、係合片４９ｂにより、搬出コンベヤ４４上の面材Ｗを搬出ストッパ５７ｂ（図８）に当たる搬出位置まで払い出す。搬出位置まで払い出された板材Ｗは、人手により、またはこの面状建材加工装置に付設される搬出装置（図示せず）によって、この面状建材加工装置から搬出する。   When machining of all the rows is completed in this way, the spindle head 4 is retracted downward, the pressing of the face material W by the individual pressing mechanism 19 of the upper surface pressing mechanism 3 is released, and the lifting frame 17 is moved to the upper retracted position. Raise. Further, the chuck 52 is raised to the upper retracted position in FIG. In this state, the chain 49a in the discharging mechanism 49 of the unloading mechanism 44 (FIG. 4) is rotated, and the unloading position where the face material W on the unloading conveyor 44 hits the unloading stopper 57b (FIG. 8) by the engagement piece 49b. Pay out. The board | plate material W paid out to the carrying-out position is carried out from this planar building material processing apparatus manually or by the carrying-out apparatus (not shown) attached to this planar building material processing apparatus.

この構成の面状建材加工装置によると、上記のように、面材Ｗを加工テーブル２上に押し付け、その押し付けられた裏面側から回転工具９による加工が行われる。そのため、被加工物である面材Ｗの加工基準面と、加工装置の加工テーブル上面である装置基準面を合わせる形態で面材Ｗを配置し、かつ密着させ、この加工基準面と装置基準面が密着した状態で加工が行われることになる。そのため、面材Ｗに板厚のばらつきや反り等が生じていても、この面材Ｗの加工基準面に対して精度良く加工することができ、図１２のような取付穴５２の加工においては、加工基準面に対する深さＤａ，Ｄ０（図７（Ｂ））を高精度に加工することができる。面材Ｗは外壁パネルの外壁面材であるが、裏面に取付用の穴加工を行うにつき、反転させる必要がないため、外壁パネルの生産ラインの簡素化にもつながる。
According to the planar building material processing apparatus having this configuration, the surface material W is pressed onto the processing table 2 as described above, and processing by the rotary tool 9 is performed from the pressed back side. Therefore, the face material W is arranged and brought into close contact with the processing reference surface of the face material W that is a workpiece and the device reference surface that is the upper surface of the processing table of the processing apparatus. The processing is performed in a state where the two are in close contact with each other. Therefore, even if the thickness or warpage of the face material W is generated, it can be processed with high accuracy with respect to the processing reference surface of the face material W. In the processing of the mounting hole 52 as shown in FIG. The depths Da and D0 (FIG. 7B) with respect to the processing reference surface can be processed with high accuracy. Although the surface material W is the outer wall surface material of the outer wall panel, per perform drilling for mounting on the back, since it is not necessary to reverse, leading to simplification of the production line of the outer wall panel.

また、主軸ヘッド４を１列に並べて可動ベッド１０に複数台設置し、可動ベッド１０を移動させることで主軸ヘッ４ドを移動させるようにしたため、面材Ｗに対して複数箇所の同じ形状の加工が同時に行えて、加工時間が短縮される。外壁パネルの外壁面材等の場合は、取付穴７２を、パネルフレーム７４に沿って複数並べて設けるが、このような１列に並ぶ複数箇所の同時加工が効率的に行える。各主軸ヘッド４は、可動ベッド１０に対して個々に位置調整可能としたため、加工穴７２の配列ピッチが種々異なる面材Ｗについても、複数箇所の加工穴７２の同時加工が行える。   Further, since the spindle heads 4 are arranged in a row and installed in the movable bed 10, and the spindle head 4 is moved by moving the movable bed 10, the spindle head 4 has the same shape at a plurality of locations with respect to the face material W. Processing can be performed at the same time and processing time is shortened. In the case of an outer wall material or the like of the outer wall panel, a plurality of mounting holes 72 are provided side by side along the panel frame 74, and such simultaneous processing of a plurality of locations arranged in one row can be performed efficiently. Since each spindle head 4 can be individually adjusted with respect to the movable bed 10, the machining holes 72 at a plurality of locations can be simultaneously machined even with respect to the face material W having different arrangement pitches of the machining holes 72.

また、上記搬入搬出機構６を設け、面材搬入方向位置決め機構部４２、および面材直交方向位置決め機構部４３を設けたため、面材Ｗの搬入搬出が効率的に行え、かつ面材Ｗの加工テーブル２に対する直交２軸方向の位置決めが精度良く行える。そのため、面材Ｗの加工基準面に対する深さだけでなく、加工基準面に沿う方向の寸法についても精度良く加工することができる。   Further, since the carry-in / carry-out mechanism 6 is provided, and the face material loading direction positioning mechanism portion 42 and the face material orthogonal direction positioning mechanism portion 43 are provided, the loading and unloading of the face material W can be performed efficiently and the processing of the face material W is performed. Positioning with respect to the table 2 in two orthogonal axes can be performed with high accuracy. Therefore, not only the depth of the face material W with respect to the processing reference surface, but also the dimension in the direction along the processing reference surface can be processed with high accuracy.

面材搬入方向位置決め機構部４２は、面材Ｗをチャック５２で把持して進退させるため、面材Ｗの移動が、滑り等を生じることなく確実に行える。このチャック５２に面材Ｗの搬入側の端面を当接させる基準面Ｓを設け、面材押し込み機構５４で面材Ｗをチャック５２の基準面Ｓに押し付けるため、面材Ｗの平面方向の移動や位置決めが、より精度良く行える。また、主軸ヘッド４には、回転工具９の近傍で工具先端側へ圧縮空気を吹き付けるノズル６２を設けたため、加工穴中の切削粉塵を外部に強制飛散させることができる。そのため、残留粉塵による加工効率や加工品質の低を回避することができる。   Since the face material carrying-in direction positioning mechanism portion 42 holds the face material W with the chuck 52 and moves it forward and backward, the face material W can be reliably moved without causing a slip or the like. A reference surface S for bringing the end face on the carry-in side of the face material W into contact with the chuck 52 is provided, and the face material W is pressed against the reference surface S of the chuck 52 by the face material pushing mechanism 54. And positioning can be performed with higher accuracy. In addition, since the spindle head 4 is provided with the nozzle 62 that blows compressed air toward the tool tip in the vicinity of the rotary tool 9, the cutting dust in the machining hole can be forcibly scattered outside. Therefore, it is possible to avoid low processing efficiency and processing quality due to residual dust.

なお、上記実施形態は、穴加工を行う場合につき説明したが、この面状建材加工装置は三次元での加工のみではなく、二次元での加工、切削や、切断加工等を行うこともできる。   In addition, although the said embodiment demonstrated about the case where hole processing was performed, this planar building material processing apparatus can also perform not only three-dimensional processing but two-dimensional processing, cutting, cutting processing, etc. .
