Description

【0001】
【発明の属する技術分野】
この発明は、セラミックグリーンシート等、薄板状ワークを切断(ハーフカットを含む)するシート切断機に係るものであり、詳しくは、カッターの清掃装置に関する。
【0002】
【従来の技術】
上記のような切断機として特許文献1には、前後方向に移動する回転テーブル上にシート状ワークを載せ、そのシート状ワークの上方からリニアモータ駆動などで昇降するようにしたカッターを昇降させて前後方向に所望のピッチで送って、シート状ワークに平行な切れ目を所望数形成し、次いで回転テーブルを90度旋回して、ワークの方向を90度変え、同様の切断作業を行なって先に形成された切れ目と直交する切れ目を入れ、シート状ワークを矩形に切断(またはハーフカット)するようにしているものが開示されると共に、カッタが昇降する貫通孔を有する中間フレームを設け、その中間フレームに設けたリニアガイド機構によりカッタ刃先のクリーナ部をカッタ長手に沿って移動可能に案内し、そのクリーナ部を中間フレームに設けた周回ベルトに接続してクリーナ部をカッタに沿って移動させてカッタ刃先を清掃する清掃装置が開示されている。
また特許文献2には、カッタの一側面に沿ってガイドシャフトと走行シャフトとを上下に並設し、走行シャフトに沿って移動するロッドレスシリンダにクリーナ部(払拭部)を設けてカッタを清掃するものが開示されている。なお、分野を異にするが、カッタ清掃装置としては特許文献3、4のものもある。
また、カッタを前後一対設けたシート切断装置としては、例えば株式会社堀鉄工所製のK−NC切断機が知られている。

【発明が解決しようとする課題】
上記特許文献1のものでは、カッタが貫通する中間フレームに清掃装置を備えている。そのため、カッタの前後に中間フレームが配置されていて、カッタ交換や刃先点検の際に中間フレーム(およびリニアガイド機構など)が邪魔になり、作業しづらい問題がある。特許文献2のものでも、カッタの一方の側面に面してガイドシャフトや走行シャフトが設けてあるので、このガイドシャフトなどの設けてある側からのカッタに対する接近性は良いとはいえない問題がある。本願の課題は、カッタ前後側から清掃装置を無くすことのできるカッタ刃先の清掃装置を提供するものである。また本願の他の課題は、構成を簡易とする前記清掃装置を提供するものである。
【0005】
【課題を解決するための手段】
上記課題解決のため、本願シート切断機のカッタ清掃装置では、テーブル上の薄板状ワークに対して昇降するカッタの刃面を清掃する清掃具をカッタ刃面の長手に沿って移動するようにしたシート切断機のカッタ清掃装置において、カッタの長手端外側に、先端に清掃具を備えた保持杆をカッタの長手に沿って進退可能に設け、前記保持杆を前進させて清掃具をカッタ長手外側となる退避位置からカッタ刃先に沿って移動して刃先を清掃した後、保持杆を後退して清掃具を前記退避位置に戻すように構成したことを特徴とする。これによれば、刃先清掃時のみ清掃具がカッタの長手内側に入り込み、清掃が終わるとカッタの長手端面の外側の退避位置に戻るので、清掃しないときにはカッタの前後側に清掃装置が無く、カッタ交換や刃先確認が容易となる。
【0006】
保持杆をカッタの長手端の両外側に夫々配置し、清掃具がカッタ両側から進入してくるようにすると良い。これによれば、退避位置に戻るまでの時間は、カッタ長手の一方のみに保持杆を配置した場合に比べて半分にできる。
シート切断機がカッタを前後一対備えている場合、一方のカッタの刃先を清掃する清掃具を備えた保持杆と他方のカッタの刃先を清掃する清掃具を備えた保持杆とを、共通の駆動源で一体に進退するようにすると好適である。これによれば、駆動源を保持杆ごとに設ける場合に比べて構成が簡易となる。
【0007】
【発明の実施の形態】
本願発明を実施するシート切断機1において、フレーム2の支持板3には、前後方向に送りねじ機構4で所定ピッチずつ送られるように送りテーブル5が案内されている。その送りテーブル5には、垂直軸線回りに90度回転割出される割出テーブル6が備えてある。割出テーブル6上には、セラミックグリーンシートのごとき薄板状ワークWが吸着保持される。割出テーブル6に刃先を下向きとしたカッタ7,8は前後2枚ある。各カッタ7,8は、夫々カッタホルダ9,10に着脱可能に保持されている。カッタホルダ9,10は、それぞれ送りモータ11,12を駆動することで夫々個別に送りねじ機構13,14を介して昇降するようになっている。長方形の薄板状ワークWを切断するため、カッタ7,8の刃渡りは長短2種類となっている。短いカッタ7で、長辺方向に所定ピッチで前後方向の切れ目を入れ、その後、割出テーブル6を90度旋回してワークWの方向を90度変え、今度は長いカッタ8で短辺方向に所定ピッチで切れ目を入れ、長方形の薄板状ワークWを小さな矩形片に切断(もしくはハーフカット)するようにしてある。2つのカッタ7,8は同時に昇降することはなく、一方が昇降して切断作業を行なっている時、他方はワークWから大きく離れた待機位置P1に停止、保持されている。切断作業が終わったカッタ7(8)は待機位置P1に上昇して停止されるようにしてある。
【0008】
送りテーブル5の左右両側には、フレーム2の支持板3から左右フレーム15,16が立設されている。左右フレーム15,16の上端には、前記待機位置P1にある前後の各カッタ7,8に対して、カッタ7,8の長手方向の両端外側となる位置に、ガイド部材17が取り付けてある。ガイド部材17は各カッタ7,8の夫々刃厚方向外側となる位置に、カッタ長手に平行な水平方向のガイド孔18が設けてある。ガイド孔18には夫々保持杆19がカッタ7,8長手方向に進退自在に案内されている。カッタ7の前側、カッタ8の後側において、各保持杆19の互いに向かい合う先端には清掃具20が取り付けてある。清掃具20は、保持杆19先端に固着されるブラケット21先端に、ニトリルゴム等の弾性材やスポンジなどから成り、互いに圧接する一対のクリーニング部材22を取り付けて構成されている。清掃時、カッタ刃先はクリーニング部材22の圧接している部分に挟まれるが、カッタ刃先を挟んでクリーニング部材22がカッタ長手に移動しても、クリーニング部材22は回転することはない。図5に示すように、ブラケット21は、カッタ7(8)が進入するためのスリット23が前後壁21a,21bに形成された上側が開放した箱形状となっており、内側がゴミ受け24となっている。
【0009】
前後のカッタ7,8の長手方向の右側と左側においては、それぞれ対応する左右フレーム15,16にブラケット25が固着してある。ブラケット25には中間軸26が回転自在に支持してある。中間軸26の一端には短レバー27の一端が固着され、短レバー27他端は駆動シリンダ28のピストンロッド29に回動可能に軸着してある。中間軸26には更に、前記前後の保持杆19と対応した位置に2つの長レバー30の一端が固定されている。長レバー30の他端には長孔31が設けてあり、その長孔31は、対応する保持杆19とピン連結してある。カッタ7,8の右側において、前記シリンダ28のピストンロッド29が前進端(上昇端)に突出した時、前後のカッタ7,8の右側の2つの清掃具20はカッタ7,8の長手端面7e,8eより外側の退避位置S1に位置し、その状態から前記シリンダ28のピストンロッド29が後退端(下降端)に向けて引き込まれると、清掃具20は退避位置S1からカッタ7,8の長手に沿ってカッタ7,8内側に向けて進入し、清掃具20の一対のクリーニング部材22が互いに接している間に刃先を挟んでカッタ7,8長手の中央まで入り込み、その後、再びピストンロッド29が前進端に向けて突出して清掃具20を退避位置S1に位置させるようにしてある。カッタ7,8の左側でも同様の構造であり、こうして前後のカッタ7,8に対して、対応する清掃具20は左右両側から進入するようになっている。
【0010】
以上の構成によれば、回転テーブル6上の薄板状ワークWに対して、図1の状態で短カッタ7を待機位置P1から下降させて、ワークWの上面近傍で昇降させつつ前後方向送りをして切断加工を行なった後、短カッタ7が待機位置P1に戻ると、左右のシリンダ28のピストンロッド29が引き込まれて、短レバー27、中間軸26、長レバー30を介して前後のカッタ7,8の左右長手端7e,8e側方の退避位置S1にあった清掃具20が、右側と左側から同時に長、短カッタ7,8内側に進入し、クリーニング部材22の間にカッタ7,8刃先を挟んで刃先を清掃しつつ中央まで入り込む。その後、シリンダ28のピストンロッド29が突出して、各清掃具20はカッタ刃先を清掃しつつ退避位置S1に戻る。この間にワークWが90度旋回され、今度は長カッタ8が待機位置P1から下降してワークWの上面近傍で昇降されて切断下降を行なう。なお、35はカッタ7(8)が待機位置P1から下降することに連動して下降し、切断加工中、ワークWの上面を押さえ込む浮き上がり防止板であり、カッタ7(8)の下方にあってカッタ7(8)が通過するための細長いスリットを有している。
【0011】
清掃時以外では、カッタ7,8の前後には清掃具20を含めた清掃装置はなく、刃先の確認やカッタ7,8の交換を邪魔するものがないので都合がよい。また、このように清掃時以外ではカッタ7,8の前後側に清掃装置がないので、保持杆19の進入経路の真上位置に、薄板状ワークWの端に設けた切断位置を示す基準線M(図1)を読み取るための左右一対のカメラCを配置することもできる。カッタ7(または8)による切断の際には、カメラCで切断すべき位置の左右の基準線Mを読み取り、2つのカメラCに正しく左右の基準線Mが読まれるように割出テーブル6を僅かに回転してアライメントし、その後、先程読んだ基準線Mがカッタ7(または8)を含む鉛直面内にくるように送りテーブル5を送り、その位置でカッタ7(または8)を降下させて切断する、という動作を繰り返すようになっている。
この実施形態では、前後一対のカッタ7,8の右側と左側で、夫々前後の清掃具20を夫々共通の1つのシリンダ28で一体に駆動するようにしているので、清掃具20夫々に駆動源を持つ場合に比べて駆動源の数を少なくできる。
【0012】
【発明の効果】
以上のように本願では、清掃時のみ、カッタの前後に清掃具が進入して清掃時以外ではカッタ前後には清掃装置が存在しないので、カッタに対する接近性が良く、カッタ交換や刃先確認が容易である。また、カッタ左右から清掃具が進入するようにしたので、カッタの一端から他端まで清掃具が移動してその後退避位置に戻るものと比べて、清掃時間が短くできる。また、前後のカッタに対する複数の清掃具を共通の駆動源で一体駆動するようにしたので、駆動源の数を少なくできる。

[Problems to be solved by the invention]
In Patent Document 1, a cleaning device is provided in an intermediate frame through which a cutter penetrates. Therefore, there is a problem that the intermediate frame is disposed before and after the cutter, and the intermediate frame (and the linear guide mechanism, etc.) hinders the operation when replacing the cutter or inspecting the cutting edge. Even in the case of Patent Document 2, since a guide shaft and a traveling shaft are provided facing one side surface of the cutter, there is a problem that the accessibility to the cutter from the side where the guide shaft is provided is not good. is there. An object of the present application is to provide a cleaning device for a cutter blade that can eliminate the cleaning device from the front and rear sides of the cutter. Another object of the present invention is to provide the cleaning device having a simple configuration.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, in the cutter cleaning device of the sheet cutting machine of the present application, a cleaning tool for cleaning the blade surface of the cutter that moves up and down on the thin work on the table is moved along the length of the cutter blade surface. In a cutter cleaning device of a sheet cutting machine, a holding rod provided with a cleaning tool at a tip is provided so as to be able to advance and retreat along a longitudinal direction of the cutter at a longitudinal end outside the cutter, and the cleaning tool is advanced by moving the holding rod forward and outside the cutter longitudinally. After moving along the cutter blade from the retracted position to clean the blade, the holding rod is retracted to return the cleaning tool to the retracted position. According to this, the cleaning tool enters the longitudinal inside of the cutter only at the time of blade edge cleaning, and returns to the retracted position outside the longitudinal end surface of the cutter when cleaning is completed. It is easy to replace and check the cutting edge.
[0006]
It is preferable that the holding rods are respectively arranged on both outer sides of the longitudinal end of the cutter so that the cleaning tool enters from both sides of the cutter. According to this, the time required to return to the retracted position can be reduced to half as compared with the case where the holding rod is disposed on only one of the longitudinal sides of the cutter.
When the sheet cutting machine includes a pair of front and rear cutters, a holding rod having a cleaning tool for cleaning the blade edge of one cutter and a holding rod including a cleaning tool for cleaning the blade edge of the other cutter are commonly driven. It is preferable to move forward and backward together at the source. According to this, the configuration is simplified as compared with the case where the driving source is provided for each holding rod.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
In the sheet cutting machine 1 embodying the present invention, a feed table 5 is guided on a support plate 3 of a frame 2 so as to be fed by a feed screw mechanism 4 at a predetermined pitch in a front-rear direction. The feed table 5 is provided with an indexing table 6 which is rotated 90 degrees around a vertical axis. On the indexing table 6, a thin work W such as a ceramic green sheet is held by suction. The indexing table 6 has two front and rear cutters 7 and 8 with the cutting edges facing downward. The cutters 7, 8 are detachably held by cutter holders 9, 10, respectively. The cutter holders 9 and 10 are individually moved up and down via feed screw mechanisms 13 and 14 by driving feed motors 11 and 12, respectively. In order to cut the rectangular thin plate-shaped workpiece W, the blades of the cutters 7 and 8 are of two types, long and short. With the short cutter 7, a cut is made in the longitudinal direction at a predetermined pitch in the long side direction. Then, the indexing table 6 is turned by 90 degrees to change the direction of the work W by 90 degrees. Cuts are made at a predetermined pitch, and the rectangular thin work W is cut (or half-cut) into small rectangular pieces. The two cutters 7 and 8 do not move up and down at the same time, and when one is up and down performing a cutting operation, the other is stopped and held at a standby position P1 far away from the work W. The cutter 7 (8) after the cutting operation is lifted to the standby position P1 and stopped.
[0008]
On both left and right sides of the feed table 5, left and right frames 15 and 16 are erected from the support plate 3 of the frame 2. Guide members 17 are attached to the upper ends of the left and right frames 15, 16 at positions outside the longitudinal ends of the cutters 7, 8 with respect to the front and rear cutters 7, 8 at the standby position P1. The guide member 17 has a guide hole 18 in the horizontal direction parallel to the longitudinal direction of the cutter, at a position outside each of the cutters 7 and 8 in the blade thickness direction. A holding rod 19 is guided in the guide hole 18 so as to be able to advance and retreat in the longitudinal direction of the cutters 7 and 8, respectively. On the front side of the cutter 7 and on the rear side of the cutter 8, a cleaning tool 20 is attached to the front ends of the holding rods 19 facing each other. The cleaning tool 20 is configured by attaching a pair of cleaning members 22 made of an elastic material such as nitrile rubber or sponge to the tip of a bracket 21 fixed to the tip of the holding rod 19 and pressed against each other. At the time of cleaning, the cutter blade is sandwiched between the portions of the cleaning member 22 that are pressed against each other. However, even if the cleaning member 22 moves in the longitudinal direction of the cutter across the cutter blade, the cleaning member 22 does not rotate. As shown in FIG. 5, the bracket 21 has a box-like shape in which the slit 23 for the cutter 7 (8) to enter is formed in the front and rear walls 21a and 21b, and the upper side is open. Has become.
[0009]
On the right and left sides of the front and rear cutters 7 and 8 in the longitudinal direction, brackets 25 are fixed to the corresponding left and right frames 15 and 16 respectively. An intermediate shaft 26 is rotatably supported by the bracket 25. One end of a short lever 27 is fixed to one end of the intermediate shaft 26, and the other end of the short lever 27 is pivotally mounted on a piston rod 29 of a drive cylinder 28. One ends of two long levers 30 are further fixed to the intermediate shaft 26 at positions corresponding to the front and rear holding rods 19. A long hole 31 is provided at the other end of the long lever 30, and the long hole 31 is connected to the corresponding holding rod 19 with a pin. When the piston rod 29 of the cylinder 28 projects to the forward end (upward end) on the right side of the cutters 7 and 8, the two cleaning tools 20 on the right side of the front and rear cutters 7 and 8 are moved to the longitudinal end faces 7e of the cutters 7 and 8. When the piston rod 29 of the cylinder 28 is retracted toward the retracted end (downward end) from that state, the cleaning tool 20 moves from the retracted position S1 to the longitudinal direction of the cutters 7, 8. Along the inside of the cutters 7 and 8, and while the pair of cleaning members 22 of the cleaning tool 20 are in contact with each other, enters the center of the longitudinal direction of the cutters 7 and 8 with the cutting edge interposed therebetween, and then returns to the piston rod 29 again. Protrudes toward the forward end and positions the cleaning tool 20 at the retracted position S1. The same structure is applied to the left side of the cutters 7 and 8, so that the corresponding cleaning tools 20 enter the front and rear cutters 7 and 8 from both left and right sides.
[0010]
According to the above-described configuration, the short cutter 7 is lowered from the standby position P1 in the state of FIG. When the short cutter 7 returns to the standby position P1 after the cutting process, the piston rods 29 of the left and right cylinders 28 are retracted, and the front and rear cutters are moved through the short lever 27, the intermediate shaft 26, and the long lever 30. The cleaning tool 20 located at the retreat position S1 on the left and right longitudinal ends 7e and 8e of the right and left longitudinal ends 7 and 8 simultaneously enters the inside of the long and short cutters 7 and 8 from the right side and the left side. Insert into the center while cleaning the cutting edge across the eight cutting edges. Thereafter, the piston rod 29 of the cylinder 28 projects, and each cleaning tool 20 returns to the retracted position S1 while cleaning the cutter blade. During this time, the work W is turned by 90 degrees, and the long cutter 8 descends from the standby position P1 and moves up and down near the upper surface of the work W to perform cutting and lowering. Reference numeral 35 denotes a lifting prevention plate which lowers in conjunction with the lowering of the cutter 7 (8) from the standby position P1 and presses the upper surface of the work W during cutting, and is located below the cutter 7 (8). It has an elongated slit through which the cutter 7 (8) passes.
[0011]
Except during cleaning, there is no cleaning device including the cleaning tool 20 before and after the cutters 7 and 8, which is convenient because there is no obstacle to confirming the cutting edge and replacing the cutters 7 and 8. In addition, since there is no cleaning device on the front and rear sides of the cutters 7 and 8 except during cleaning, a reference line indicating a cutting position provided at an end of the thin plate-shaped work W is provided immediately above the entry path of the holding rod 19. A pair of left and right cameras C for reading M (FIG. 1) can also be arranged. At the time of cutting by the cutter 7 (or 8), the index table 6 is read so that the left and right reference lines M at the position to be cut by the camera C are read correctly by the two cameras C. The feed table 5 is fed so that the reference line M read earlier is in the vertical plane including the cutter 7 (or 8), and the cutter 7 (or 8) is lowered at that position. The operation of cutting and cutting is repeated.
In this embodiment, the front and rear cleaning tools 20 are driven integrally by one common cylinder 28 on the right and left sides of the pair of front and rear cutters 7 and 8, respectively. , The number of drive sources can be reduced.
[0012]
【The invention's effect】
As described above, in the present application, the cleaning tool enters the front and rear of the cutter only at the time of cleaning, and since there is no cleaning device before and after the cutter except at the time of cleaning, the accessibility to the cutter is good, and it is easy to replace the cutter and check the blade edge. It is. In addition, since the cleaning tool enters from the left and right sides of the cutter, the cleaning time can be reduced as compared with the case where the cleaning tool moves from one end to the other end of the cutter and then returns to the retracted position. Further, since a plurality of cleaning tools for the front and rear cutters are driven integrally by a common drive source, the number of drive sources can be reduced.
