マーキング装置及び板材加工システムMarking device and plate material processing system
　本発明は、板状のワークにマーキングするマーキング装置[marking machine]と、板状のワークを加工する板材加工システム[plate machining system]とに関する。 The present invention relates to a marking device [marking machine] for marking a plate-shaped workpiece and a plate material processing system [plate-machining system] for processing a plate-shaped workpiece.
　例えば、パンチプレスやレーザ加工機などの板材加工機[plate machining machine]によって、板状のワークから複数の加工部品[machined part]を切断分離される。この場合、各加工部品には、その名称などがマーキングされる（特許文献１，２参照）。 For example, a plurality of machined parts are cut and separated from a plate-shaped workpiece by a plate material processing machine [plate machine machining machine] such as a punch press or a laser processing machine. In this case, the name of each processed part is marked (see Patent Documents 1 and 2).

　特許文献１は、板材加工機によって加工された板状のワークをＸ軸方向に搬送する搬送路の上方にＹ軸方向に延在するＹ軸フレームを備え、ワークにマーキングする印字装置[marking device]がＹ軸フレームに往復動自在に設けられている構成が開示されている。 Patent Document 1 discloses a printing apparatus that includes a Y-axis frame extending in the Y-axis direction above a conveyance path for conveying a plate-like workpiece processed by a plate material processing machine in the X-axis direction, and marks the workpiece [marking device Is provided on the Y-axis frame so as to be reciprocally movable.
　前記特許文献２には、板材加工機によって加工された板状のワークをＸ軸方向に搬送する搬送路の上方にＸ軸方向に往復動自在なＹ軸ガイド部材を備え、マーキングヘッドがＹ軸方向に移動自在にＹ軸ガイド部材に設けられている構成が記載されている。 In Patent Document 2, a Y-axis guide member that can reciprocate in the X-axis direction is provided above a conveyance path for conveying a plate-like workpiece processed by a plate material processing machine in the X-axis direction, and the marking head has a Y-axis. A configuration is described in which the Y-axis guide member is movable in the direction.
　特許文献１に開示された構成においては、ワークに対してＹ軸方向にマーキングすることができる。また、特許文献２に開示された構成においては、ワークに対してＸ軸方向及びＹ軸方向の両方向にマーキングすることができる。 In the configuration disclosed in Patent Document 1, the workpiece can be marked in the Y-axis direction. Further, in the configuration disclosed in Patent Document 2, it is possible to mark the workpiece in both the X-axis direction and the Y-axis direction.
　マーキング装置としてインクジェットプリンタを採用すると、ワークに横方向に印字する場合も縦方向に印字する場合も、インクジェットプリンタヘッドの特性として、印字した文字の方向性[orientation of letter(s)]は常に一定である。すなわち、印字した文字の頭部は常に上側である。したがって、例えば「ＸＹＺ」と横方向に印字したときには、文字の方向を一方向（例えば文字の頭部を上側）に保持してＸＹＺの文字が横方向に並べて印字される。ところが、縦方向に印字したときには、文字の方向が横方向の印字の場合と同方向（文字の頭部を上側）に保持して、ＸＹＺの文字が縦方向に並べて印字される。 When an inkjet printer is used as the marking device, the orientation of the printed characters [orientation of letter (s)] is always constant as a characteristic of the inkjet printer head, regardless of whether the workpiece is printed horizontally or vertically. It is. That is, the head of the printed character is always on the upper side. Therefore, for example, when “XYZ” is printed in the horizontal direction, the character direction is held in one direction (for example, the head of the character is on the upper side), and XYZ characters are printed in the horizontal direction. However, when printing in the vertical direction, XYZ characters are printed side by side in the vertical direction while keeping the direction of the characters in the same direction as in the case of printing in the horizontal direction (the head of the character is on the upper side).
　よって、ワークに対する印字方向[printing direction]が横方向の場合と縦方向の場合とで、文字の方向性と文字の配置方向[arrangement direction of letters]（印字方向）との関係が異なる。その結果、印字した文字全体を読む場合、読み難い場合がある。 Therefore, the relationship between the directionality of characters and the direction of arrangement of characters [arrangement direction of letters] (printing direction) differs depending on whether the printing direction [printing direction] for the workpiece is horizontal or vertical. As a result, it may be difficult to read the entire printed character.
　したがって、印字方向が横方向であっても縦方向であっても、文字の方向性と文字の配置方向との関係が常に一定であることが望まれている。 Therefore, it is desired that the relationship between the directionality of characters and the direction of arrangement of characters is always constant regardless of whether the printing direction is horizontal or vertical.

　以下、図面を参照しつつ実施形態について説明する。図１に示されるように、本実施形態の板材加工システムは、パンチプレスやレーザ加工機などの板材加工機１を備えている。板材加工機１のＸ軸方向の一側には、板材加工機１に搬入される、又は、板材加工機１から搬出される板状のワーク[plate-shaped workpiece]Ｗを一時的に支持するワーク支持テーブル３が配置されている。ワーク支持テーブル３のＸ軸方向の一側（板材加工機１の反対側）には、ワーク貯留部[workpiece stocker]５が配置されている。ワーク貯留部５は、板材加工機１によって複数の加工部品が加工された後のワーク、又は、板材加工機１に搬入されるワークを貯留する。 Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG. 1, the plate material processing system of the present embodiment includes a plate material processing machine 1 such as a punch press or a laser processing machine. On one side of the plate material processing machine 1 in the X-axis direction, a plate-shaped workpiece [plate-shaped workpiece] W that is carried into or out of the plate material processing machine 1 is temporarily supported. A work support table 3 is arranged. On one side of the workpiece support table 3 in the X-axis direction (opposite side of the plate material processing machine 1), a workpiece storage section [workpiece stocker] 5 is arranged. The work storage unit 5 stores a work after a plurality of processed parts are processed by the plate material processing machine 1 or a work carried into the plate material processing machine 1.
　板材加工機１とワーク貯留部５との間には、板材加工機１によって加工される加工部品（図１には示されていない）、又は、板材加工機１によって加工された加工部品にマーキングするマーキング装置７が設けられている。即ち、マーキング装置７は、板材加工機１にワークＷを搬入、又は、板材加工機１から搬出するワーク搬送路に設けられている。 Between the plate material processing machine 1 and the workpiece storage part 5, a processed part processed by the plate material processing machine 1 (not shown in FIG. 1) or a processed part processed by the plate material processing machine 1 is marked. A marking device 7 is provided. In other words, the marking device 7 is provided in a workpiece conveyance path that carries the workpiece W into or out of the plate material processing machine 1.
　マーキング装置７は、ワークＷをＸ軸方向に搬送するワーク搬送路におけるパスラインの上方位置に、Ｙ軸方向に延在するＹ軸ガイド部材９を備えている。Ｙ軸ガイド部材９には、Ｙ軸ガイド部材９に沿ってＹ軸方向に往復動自在なＹ軸スライダ１５が設けられている。 The marking device 7 includes a Y-axis guide member 9 extending in the Y-axis direction at a position above the pass line in the work conveyance path for conveying the workpiece W in the X-axis direction. The Y-axis guide member 9 is provided with a Y-axis slider 15 that can reciprocate in the Y-axis direction along the Y-axis guide member 9.
　より詳細には、図２及び図３に示されるように、Ｙ軸ガイド部材９の両端は支柱１１によって支持されている。また、Ｙ軸ガイド部材９は、Ｙ軸方向に水平に延在するガイドレール１３を備えている。ガイドレール１３には、Ｙ軸スライダ１５が往復動自在に支持されている。Ｙ軸スライダ１５を往復動させるために、Ｙ軸ガイド部材９は、Ｙ軸方向に沿ってラック[rack]１７を備えている。ラック１７に噛合したピニオン[pinion]（図示せず）を回転するために、Ｙ軸スライダ１５には、サーボモータなどのＹ軸モータ１９が装着されている。 More specifically, as shown in FIGS. 2 and 3, both ends of the Y-axis guide member 9 are supported by the columns 11. The Y-axis guide member 9 includes a guide rail 13 that extends horizontally in the Y-axis direction. A Y-axis slider 15 is supported on the guide rail 13 so as to reciprocate. In order to reciprocate the Y-axis slider 15, the Y-axis guide member 9 includes a rack 17 along the Y-axis direction. In order to rotate a pinion (not shown) meshed with the rack 17, a Y-axis motor 19 such as a servo motor is mounted on the Y-axis slider 15.
　Ｙ軸モータ１９の回転を制御することにより、Ｙ軸スライダ１５をＹ軸方向に移動して位置決めすることができる。なお、Ｙ軸スライダ１５のＹ軸方向の基準位置からの移動位置は、Ｙ軸モータ１９が備えるロータリーエンコーダなどの位置検出器[position detector]によって検出できる。 By controlling the rotation of the Y-axis motor 19, the Y-axis slider 15 can be moved and positioned in the Y-axis direction. The movement position of the Y-axis slider 15 from the reference position in the Y-axis direction can be detected by a position detector [position の detector] such as a rotary encoder provided in the Y-axis motor 19.
　Ｙ軸スライダ１５は、Ｘ軸方向に長いＸ軸ガイド部材２１を備えている。Ｘ軸ガイド部材２１は、Ｌ字形状に屈曲されたＸ軸スライダ２３（図４参照）が移動自在に支持している。より詳細には、Ｘ軸ガイド部材２１は、Ｙ軸スライダ１５に一体的に設けられた支持ブラケット２５に取付けられている。Ｘ軸ガイド部材２１内に回転自在に設けられたボールネジ（図示せず）には、Ｘ軸スライダ２３に設けられたボールナット（図示せず）が移動自在に螺合している。 The Y-axis slider 15 includes an X-axis guide member 21 that is long in the X-axis direction. The X-axis guide member 21 is movably supported by an X-axis slider 23 (see FIG. 4) bent in an L shape. More specifically, the X-axis guide member 21 is attached to a support bracket 25 provided integrally with the Y-axis slider 15. A ball nut (not shown) provided on the X-axis slider 23 is movably engaged with a ball screw (not shown) provided rotatably in the X-axis guide member 21.
　したがって、Ｘ軸ガイド部材２１上に装着されたサーボモータなどのＸ軸モータ２７の回転をエンドレスチェーン（図示せず）を介してボールネジに伝達してボールネジを回転させると、Ｘ軸スライダ２３がＸ軸方向に移動して位置決めすることができる。なお、Ｘ軸ガイド部材２１に沿ってＸ軸スライダ２３を移動（位置決め）する構成は、前述した構成に限られず、その他の構成（例えば、リニアモータを採用した構成）でもよい。 Therefore, when the rotation of the X-axis motor 27 such as a servo motor mounted on the X-axis guide member 21 is transmitted to the ball screw via an endless chain (not shown) and the ball screw is rotated, the X-axis slider 23 becomes X It can be moved and positioned in the axial direction. The configuration for moving (positioning) the X-axis slider 23 along the X-axis guide member 21 is not limited to the configuration described above, and other configurations (for example, a configuration employing a linear motor) may be used.
　Ｘ軸スライダ２３には、Ｘ軸及びＹ軸方向に直交する垂直方向（Ｚ軸方向）の回転軸（図示せず）を備えたＣ軸モータ２９が装着されている。Ｃ軸モータ２９の垂直な回転軸には、揺動ブラケット３１が一体的に取付けられている。そして、揺動ブラケット３１は、前述した回転軸から水平に僅かに離れた位置（すなわち、回転軸から偏在した位置）に、マーキングヘッド３３を備えている。 The X-axis slider 23 is equipped with a C-axis motor 29 having a rotation axis (not shown) in the vertical direction (Z-axis direction) orthogonal to the X-axis and Y-axis directions. A swing bracket 31 is integrally attached to a vertical rotation shaft of the C-axis motor 29. The swing bracket 31 includes a marking head 33 at a position slightly apart from the above-described rotation axis (that is, a position unevenly distributed from the rotation axis).
　Ｃ軸モータ２９の垂直な回転軸は上下動自在に設けられている。回転軸を上下動するために、Ｃ軸モータ２９には、回転軸の位置を上下方向（Ｚ軸方向）に調節自在なＺ軸モータ３５が装着されている。即ち、Ｚ軸モータ３５によって、マーキングヘッド３３を、（Ｃ軸モータ２９及び揺動ブラケット３１を介して）ワークＷに対して接近離反する方向に位置調節自在である。 The vertical rotation axis of the C-axis motor 29 is provided so as to be movable up and down. In order to move the rotating shaft up and down, the C-axis motor 29 is equipped with a Z-axis motor 35 that can adjust the position of the rotating shaft in the vertical direction (Z-axis direction). That is, the Z-axis motor 35 can adjust the position of the marking head 33 in the direction of approaching and moving away from the workpiece W (via the C-axis motor 29 and the swing bracket 31).
　マーキングヘッド３３は、インクジェットプリンタヘッドで構成されている。ワークＷに印字する文字の方向性と、揺動ブラケット３１の方向性（揺動位置：回動位置）との間には、常に一定の関係がある。したがって、Ｃ軸モータ２９によって揺動ブラケット３１を回動すると、揺動ブラケット３１の回動によって印字する文字の方向性が変わる。本実施形態においては、図２及び図３に示されるように、揺動ブラケット３１を水平に９０°回動することができる。よって、文字の方向性をＸ軸方向及びＹ軸方向（すなわち、縦方向及び横方向）に変更することができる。なお、揺動ブラケット３１の回転角度は９０°に限られず、３６０°に設定することが望ましい。 The marking head 33 is composed of an inkjet printer head. There is always a fixed relationship between the directionality of the characters printed on the workpiece W and the directionality of the swing bracket 31 (swing position: rotation position). Therefore, when the swing bracket 31 is rotated by the C-axis motor 29, the directionality of characters to be printed is changed by the rotation of the swing bracket 31. In the present embodiment, as shown in FIGS. 2 and 3, the swing bracket 31 can be rotated 90 degrees horizontally. Therefore, the directionality of the character can be changed to the X-axis direction and the Y-axis direction (that is, the vertical direction and the horizontal direction). The rotation angle of the swing bracket 31 is not limited to 90 °, and is preferably set to 360 °.
　上述した構成において、図５に示されるように、ワークＷに複数の加工部品３７Ａ，３７Ｂ，３７Ｃ，３７Ｄを配置して（割り付けて）、レーザ加工機によって加工部品３７Ａ～３７ＤをミクロジョイントでワークＷに接続された状態に切断する。そして、マーキング装置７の位置を通過したときに、加工部品３７Ａ～３７Ｄに予め設定されたマーキング開始位置３９から予め設定されたマーキング方向にマーキング４１が行われる。なお、以下、マーキングヘッド３３が垂直な回転軸回りに３６０°回動可能であるものとして説明する。 In the configuration described above, as shown in FIG. 5, a plurality of processed parts 37A, 37B, 37C, and 37D are arranged (assigned) to the work W, and the processed parts 37A to 37D are microjointed by a laser processing machine. Disconnect to connect to W. Then, when passing the position of the marking device 7, the marking 41 is performed in the marking direction set in advance from the marking start position 39 set in advance in the processed parts 37A to 37D. In the following description, it is assumed that the marking head 33 can be rotated 360 ° around a vertical rotation axis.
　より詳細には、マーキング装置７は、ワークＷに対するマーキングヘッド３３の動作を制御する動作制御装置[motion control device]４３を備えている。動作制御装置４３は、移動動作制御部[moving action controller]（動作制御部[motion controller]）４５を備えている。移動動作制御部４５は、ワークＷ上のマーキング開始位置３９（図５参照）及びマーキング方向（例えば、Ｘ軸方向・Ｙ軸方向）に対応して、マーキングヘッド３３の位置及び方向性（指向方向oriented direction）並びにワークＷに対するマーキングヘッド３３の移動方向（例えば、Ｘ軸方向・Ｙ軸方向）を制御する。 More specifically, the marking device 7 includes a motion control device 43 that controls the operation of the marking head 33 with respect to the workpiece W. The motion control device 43 includes a moving motion control unit [moving action controller] (motion control unit [motion） controller]) 45. The movement operation control unit 45 corresponds to the marking start position 39 on the workpiece W (see FIG. 5) and the marking direction (for example, the X-axis direction and the Y-axis direction), and the position and directionality (directing direction) of the marking head 33. oriented direction) and the moving direction of the marking head 33 with respect to the workpiece W (for example, the X axis direction and the Y axis direction) are controlled.
　移動動作制御部４５は、Ｙ軸モータ１９、Ｘ軸モータ２７、Ｃ軸モータ２９及びＺ軸モータ３５の動作[operations]を制御して、マーキングヘッド３３の移動動作を制御する機能を有する。 The movement operation control unit 45 has a function of controlling the movement operation of the marking head 33 by controlling the operations of the Y-axis motor 19, the X-axis motor 27, the C-axis motor 29, and the Z-axis motor 35.
　動作制御装置４３には、ネスティング装置[nesting devise]４７が接続されている。ネスティング装置４７は、コンピュータで構成されている。そして、ネスティング装置４７は、ワークＷに配置する複数の加工部品３７Ａ～３７Ｄの形状データ、ワークＷの基準位置に対する加工部品３７Ａ～３７Ｄの配置位置データ、及び、加工部品３７Ａ～３７Ｄのマーキング開始位置３９の位置データ（マーキング開始位置データ）を格納した位置データメモリ４８を備えている。位置データメモリ４８は、加工部品３７Ａ～３７Ｄの傾斜角データも格納している。 A nesting device [nesting devise] 47 is connected to the operation control device 43. The nesting device 47 is configured by a computer. Then, the nesting device 47 forms the shape data of the plurality of processed parts 37A to 37D arranged on the workpiece W, the arrangement position data of the processed parts 37A to 37D with respect to the reference position of the workpiece W, and the marking start position of the processed parts 37A to 37D. A position data memory 48 storing 39 position data (marking start position data) is provided. The position data memory 48 also stores tilt angle data of the processed parts 37A to 37D.
　マーキング開始位置３９は、加工部品３７Ａ（代表して加工部品３７Ａの場合について説明する）の基準位置４９Ａ（外形の一頂点）から一方の辺４９Ｂに沿って寸法Ａ、かつ、基準位置４９Ａから他方の辺４９Ｃに沿って寸法Ｂの位置に予め設定されている。マーキング開始位置３９からのマーキング方向（印字方向）は、一方の辺４９Ｂに沿った方向に予め設定されている。予め設定された寸法Ａ及びＢ並びに印字方向（マーキング方向）は、ネスティング装置４７のパラメータメモリ５１に格納されている。 The marking start position 39 is a dimension A along one side 49B from the reference position 49A (one vertex of the outer shape) of the processed part 37A (typically described for the case of the processed part 37A), and the other from the reference position 49A. The position of the dimension B is preset along the side 49C. The marking direction (printing direction) from the marking start position 39 is set in advance in a direction along one side 49B. The preset dimensions A and B and the printing direction (marking direction) are stored in the parameter memory 51 of the nesting device 47.
　したがって、複数の加工部品３７Ａ～３７Ｄを配置したワークＷを板材加工機１によって加工する際には、ネスティング装置４７によって作成されたネスティングデータが、板材加工機１の動作を制御するＮＣ装置に伝送される。そして、ネスティングデータに従って、ワークＷが加工される。板材加工機１によって加工された後のワークＷは、ワーク支持テーブル３からマーキング装置７を経てワーク貯留部５に搬送される。 Therefore, when processing the workpiece W on which the plurality of processed parts 37A to 37D are arranged by the plate material processing machine 1, the nesting data created by the nesting device 47 is transmitted to the NC device that controls the operation of the plate material processing machine 1. Is done. Then, the workpiece W is processed according to the nesting data. The workpiece W after being processed by the plate material processing machine 1 is conveyed from the workpiece support table 3 to the workpiece storage unit 5 via the marking device 7.
　マーキング装置７の位置で、ワークＷに加工された複数の加工部品３７Ａ～３７Ｄにマーキングが行われる。この際、ネスティング装置４７から動作制御装置４３のネスティングデータメモリ５３に入力されたネスティングデータに基づいて、動作制御部４５がマーキングヘッド３３の動作を制御する。 At the position of the marking device 7, marking is performed on a plurality of processed parts 37A to 37D processed into the workpiece W. At this time, the operation control unit 45 controls the operation of the marking head 33 based on the nesting data input from the nesting device 47 to the nesting data memory 53 of the operation control device 43.
　すなわち、ワークＷの加工部品３７Ａ～３７Ｄには、加工部品３７Ａ～３７Ｄに予め設定（規定）された基準位置４９から寸法Ａ及びＢの位置であるマーキング開始位置３９から一方の辺（４９Ｂ）に沿ってマーキング（印字）が行われる。 That is, the processed parts 37A to 37D of the workpiece W are moved from the reference position 49 set in advance to the processed parts 37A to 37D to the one side (49B) from the marking start position 39 that is the position of the dimensions A and B. Marking (printing) is performed along.
　この際、マーキングヘッド３３が回動されて印字された文字の方向性は、マーキング（印字）される文字の配置方向に対して常に一定の関係を保持するようにされている。従って、文字の方向性と文字の配置方向との関係は常に一定であり、マーキングした文字が読み難くなることがない。 At this time, the directionality of the characters printed by rotating the marking head 33 always maintains a fixed relationship with the arrangement direction of the characters to be marked (printed). Therefore, the relationship between the directionality of the characters and the character arrangement direction is always constant, and the marked characters do not become difficult to read.
　図６は、第２実施形態に係るマーキング装置７Ａの概略平面図である。上述した第１実施形態のマーキング装置７の構成要素と同一機能を有するマーキング装置７Ａの構成要素には同一符号を付して、それらの重複する説明を省略する。 FIG. 6 is a schematic plan view of a marking device 7A according to the second embodiment. Constituent elements of the marking apparatus 7A having the same functions as those of the marking apparatus 7 of the first embodiment described above are denoted by the same reference numerals, and redundant description thereof is omitted.
　マーキング装置７Ａは、Ｙ軸方向に長いＹ軸ガイド部材９に沿ってＹ軸方向に移動して位置決め自在なＹ軸スライダ１５Ａを備えている。Ｙ軸スライダ１５Ａは、制御装置（図示せず）によって制御されるＹ軸モータ（図示せず）の作動によって移動して位置決めされる。Ｙ軸スライダ１５Ａは、垂直方向（Ｚ軸方向）の軸心回りに回動自在な旋回台[turning base]６１を備えている。旋回台６１は、旋回台６１に設けられたサーボモータなどのモータ６３によって水平に旋回する。 The marking device 7A includes a Y-axis slider 15A that can be positioned by moving in the Y-axis direction along the Y-axis guide member 9 that is long in the Y-axis direction. The Y-axis slider 15A is moved and positioned by the operation of a Y-axis motor (not shown) controlled by a control device (not shown). The Y-axis slider 15 </ b> A includes a turntable 61 that is rotatable about an axis in the vertical direction (Z-axis direction). The swivel base 61 is swung horizontally by a motor 63 such as a servo motor provided on the swivel base 61.
　旋回台６１は、旋回台６１の回動軸心に直交する水平方向に移動して位置決め自在なマーキングヘッド３３を備えている。マーキングヘッド３３の移動及び位置決めは、サーボモータ（図示せず）によって行われる。より詳細には、旋回台６１は、旋回台６１の回転軸心に直交する水平方向に延伸するガイド部材６５を備えている。ガイド部材６５に移動自在に支持されたスライダ６７が、上述したマーキングヘッド３３を備えている。また、本実施形態では、スライダ６７にＺ軸モータ３５が設けられており、Ｚ軸モータ３５によって、マーキングヘッド３３をワークＷに対して接近離反する方向に位置調節自在である。 The swivel base 61 includes a marking head 33 that can be moved and positioned in a horizontal direction perpendicular to the rotational axis of the swivel base 61. The marking head 33 is moved and positioned by a servo motor (not shown). More specifically, the swivel base 61 includes a guide member 65 extending in the horizontal direction perpendicular to the rotation axis of the swivel base 61. A slider 67 movably supported by the guide member 65 includes the marking head 33 described above. In the present embodiment, the slider 67 is provided with a Z-axis motor 35, and the position of the marking head 33 can be adjusted in a direction in which the marking head 33 approaches and separates from the workpiece W by the Z-axis motor 35.
　上述した構成によって、図７（Ａ）～図７（Ｄ）に示されるように、旋回台６１が水平に回動することで、ガイド部材６５を、Ｘ軸方向及びＹ軸方向に対して所望の傾斜角度（回転角度）に傾斜（回転）させることができる。ガイド部材６５に沿ってマーキングヘッド３３を移動させつつワークＷにマーキングすることで、Ｘ軸及びＹ軸に対して傾斜した方向にマーキングできる。したがって、ワークＷ上に加工部品を斜めに（傾斜した状態で）配置しても、容易にマーキングを行うことができる。 With the above-described configuration, as shown in FIGS. 7A to 7D, the swivel base 61 rotates horizontally, so that the guide member 65 is desired in the X-axis direction and the Y-axis direction. Can be tilted (rotated) at a tilt angle (rotation angle). By marking the workpiece W while moving the marking head 33 along the guide member 65, the marking can be performed in a direction inclined with respect to the X axis and the Y axis. Therefore, even if the processed parts are arranged obliquely (in an inclined state) on the workpiece W, marking can be easily performed.
　この場合、図６及び図７に示されるように、ガイド部材６５の長手方向とマーキングヘッド３３の方向性とは常に一定の関係を保持する。したがって、ガイド部材６５の傾斜角が種々変化しても、ガイド部材６５に沿ってマーキングヘッド３３を移動することによる印字方向（文字の配列方向[aligning direction of letters]）と、印字される文字の方向性は常に一定の関係を保持する。 In this case, as shown in FIGS. 6 and 7, the longitudinal direction of the guide member 65 and the directionality of the marking head 33 always maintain a certain relationship. Therefore, even if the inclination angle of the guide member 65 changes variously, the printing direction (character alignment direction [aligning direction of letters]) by moving the marking head 33 along the guide member 65 and the character to be printed Directionality always maintains a certain relationship.
　ところで、上記説明ではガイド部材６５に対してスライダ６７が移動した。しかし、スライダ６７にマーキングヘッド３３を一体的に設けて、旋回台６１に対してガイド部材６５がその長手方向に移動してもよい。 Incidentally, in the above description, the slider 67 has moved relative to the guide member 65. However, the marking head 33 may be provided integrally with the slider 67, and the guide member 65 may move in the longitudinal direction with respect to the swivel base 61.
　本実施形態によれば、インクジェットプリンタヘッドで構成されたマーキングヘッド３３が垂直な軸心回りに回動自在であるので、ワークＷの表面に印字される文字の方向性（例えば、文字の上側）を、文字の配置方向（印字方向）に直交する方向に常に向けることができる。したがって、ワークＷの加工部品に文字を印字した場合、文字の方向性と配置方向との関係は常に一定に保持され、マーキングした文字が読み難くなるようなことがない。 According to the present embodiment, since the marking head 33 constituted by the ink jet printer head is rotatable around a vertical axis, the directionality of characters printed on the surface of the workpiece W (for example, above the characters) Can be always directed in a direction orthogonal to the character arrangement direction (printing direction). Therefore, when a character is printed on a processed part of the workpiece W, the relationship between the directionality of the character and the arrangement direction is always kept constant, and the marked character does not become difficult to read.
　本発明は、上記実施形態に限る限定されず、適宜の変更を行うことで他の形態でも施可能である。上記実施形態では、板材加工機１によって加工されたワークＷの加工部品にマーキングした。しかし、加工部品のワークＷ上の配置位置は、ネスティングデータによって既知である。したがって、板材加工機１にワークＷを搬入する前に、加工部品に相当する位置に予めマーキングを行うことも可能である。 The present invention is not limited to the above embodiment, and can be implemented in other forms by making appropriate changes. In the said embodiment, it marked on the workpiece of the workpiece | work W processed with the board | plate material processing machine 1. FIG. However, the arrangement position of the workpiece on the workpiece W is known from the nesting data. Therefore, before carrying the workpiece W into the plate material processing machine 1, it is also possible to perform marking in advance at a position corresponding to the processed part.
