- the controller 94 selects the first allowable range at the time of chucking and release, and selects the second allowable range at the time of normal back-and-forth driving. Specifically, the switching of the allowable range by the control unit 94 is performed when the command output to the bar supply device 50 corresponds to the operation of chucking the bar 200 or the bar 200.

(Angle deviation) deviates from the second allowable range, and the control unit 94 determines that an error has occurred in the operation of the push-button servomotor 74 and stops the operation or causes the display unit 91 to generate an excessive error. May be displayed.
- the control unit 94 selects the first allowable range at the time of chucking or releasing, so that the pusher servo motor 74 is originally driven by driving the air cylinder device 80. Even if the rotational angle to be controlled (second allowable range) deviates, if the above-described positional deviation (angle deviation) is within the first allowable range, the control unit 94 operates the push-arrow servomotor 74. Therefore, the operation is continued without stopping, and the display unit 91 is not caused to display an excessive error error. Thereby, the operation rate of the automatic lathe apparatus 100 can be improved.
- the control unit 94 drives the push-push servomotor 74 to rotate so as to suppress the positional deviation. At this time, the rotational drive current of the push-arrow servomotor 74 increases corresponding to the increase in the position deviation. The control unit 94 stops the operation as an error when the rotational drive current of the pushing arrow servomotor 74 exceeds a predetermined limit value.
- control unit 94 is provided with a current regulating means for regulating the rotational drive current of the pushing servo motor 74 so as not to exceed a predetermined value smaller than a predetermined limit value.
- a current regulating means for regulating the rotational drive current of the pushing servo motor 74 so as not to exceed a predetermined value smaller than a predetermined limit value.
- the automatic lathe device 100 of the present embodiment is an example in which the control device according to the present invention is also used as the NC control device 90 that also controls the automatic lathe body 10, but the present invention is limited to this example. It is not a thing and the control apparatus only for a bar supply apparatus may be sufficient.
- the bar supply device provided with the control device dedicated to the bar supply device as a configuration of the bar supply device is an example of the bar supply device of the present invention.

Abstract
Description
棒材供給装置は、NC工作機械の後方に配置される。
棒材供給装置は、先端にフィンガーチャックを備えた押し矢、この押し矢を前後に駆動するモータを有する。
棒材供給装置は、押し矢が前方に駆動されると、位置が固定された棒材の後端部がフィンガーチャックに差し込まれて、フィンガーチャックは棒材をチャックする(特許文献1)。
棒材供給装置は、フィンガーチャックにチャックされた状態の棒材の位置を固定し、押し矢を後方に移動させることによって、フィンガーチャックから棒材をリリースする。
モータの駆動は、制御装置で制御される。
本発明は上記事情に鑑みなされたものであって、モータの駆動力が足りない場合にも、棒材をチャックすることを可能にした棒材供給装置および棒材供給装置付きのNC工作機械を提供することを目的とする。
本発明に係る棒材供給装置付きのNC工作機械は、本発明に係る棒材供給装置を備えたNC工作機械である。
しかも、本発明に係る棒材供給装置および棒材供給装置付きのNC工作機械は、フィンガーチャックに棒材を抜き差ししたときにシリンダ装置の動作の影響を受けてモータの動作量の誤差が、フィンガーチャックに棒材を抜き差しするとき以外における動作量の誤差の許容範囲よりも大きくなっても、制御装置の誤差許容手段によって、モータの制御のエラーが発生するのを防止乃至抑制することができる。
主軸用サーボモータ30は、図3に示すように、後述するNC制御装置90の命令にしたがって駆動される。
棒材供給装置50は、自動旋盤本体10の後方であって、主軸20と一直線上に配置されている。
棒材供給装置50は、多数の棒材200をストックするとともに、そのストックされた棒材200から1本ずつを順次、自動旋盤本体10に自動的に供給する。
ベース52の内部には、棒材200をベース52に沿って前後方向に押し引きする押し矢60と、接続部材62を介して押し矢60に接続され、前後方向に沿って環状に設けられたチェーン71と、チェーン71を前後方向に駆動する押し矢用サーボモータ74およびエアシリンダ装置80とを備える。
押し矢60の前端には、フィンガーチャック61が設けられている。
フィンガーチャック61は、押し矢60の長尺方向を軸とした円筒状に形成され、その円筒の周壁には軸方向に沿って延びたすり割りが軸回りに複数形成されていて、周壁を外方に弾性変形させながらすり割りが開くことで、円筒の内部に内径よりも太い棒材200を挿入し、棒材200をチャックする。
チェーン71には、接続部材63を介してエアシリンダ装置80も連結されている。
また、エアシリンダ装置80は、フィンガーチャック61から棒材200をリリースする動作の際に、押し矢用サーボモータ74とともに、チェーン71を後方に駆動する。
エアシリンダ装置80は、チェーン71に接続されてチェーン71を前後に駆動可能な状態とチェーン71から離れてチェーン71の動きに影響を与えない状態を採り得る。
フィンガーチャック61によって棒材200をチャックするときは、棒材200がストッパ等の固定部材(図示省略)によってベース52上に固定された状態で、エアシリンダ装置80がチェーン71に接続されて押し矢用サーボモータ74とともにチェーン71を前方に駆動する。
押し矢用サーボモータ74の駆動力にエアシリンダ装置80の駆動力が加わることで、例えば直径40mm以上の太い棒材200であっても、フィンガーチャック61と棒材200との摩擦力およびすり割りを開く弾性力(嵌合抵抗力)に抗して押し矢60が前方に移動し、棒材200の後端にフィンガーチャック61が差し込まれて、フィンガーチャック61が棒材200をチャックすることができる。
回収した棒材200をフィンガーチャック61からリリースするときは、棒材200が固定部材によってベース52上に固定された状態で、エアシリンダ装置80がチェーン71側に接続されて押し矢用サーボモータ74とともにチェーン71を後方に駆動する。
押し矢用サーボモータ74の駆動力にエアシリンダ装置80の駆動力が加わることで、例えば直径40mm以上の太い棒材200であっても、フィンガーチャック61と棒材200との摩擦力(嵌合力)に抗して押し矢60が後方に移動し、フィンガーチャック61が棒材200をリリースすることができる。
棒材200をリリースした後は、固定部材による棒材200の固定は解除され、エアシリンダ装置80はチェーン71側から離れる。
NC制御装置90は、図4に示すように、自動旋盤本体10の一部に設置されており、コード化された命令等を入力する入力部92と、入力された命令等や各種の判定基準等を記憶する記憶部93と、命令等に応じて自動旋盤本体10や棒材供給装置50に対する制御信号を出力する制御部94とを備える。
動作信号により特定された動作量が誤差の許容範囲を逸脱したときは、制御部94は、押し矢用サーボモータ74の動作量の誤差が過大であると判定してその動作を停止させるとともに、表示部91に誤差過大エラーを知らせる表示を行わせる。
動作信号により特定された動作量が誤差の許容範囲を逸脱しなかったときは、制御部94は、押し矢用サーボモータ74の動作量の誤差が過大ではないと判定してその動作を停止させることなく継続させる。
つまり制御部94は、フィンガーチャック61に棒材200を抜き差しするときの押し矢用サーボモータ74の動作量の誤差を許容する誤差許容手段の一例を構成している。
記憶部93には、棒材200のチャック時およびリリース時にそれぞれ対応する押し矢用サーボモータ74の動作量の誤差の許容範囲である第1の許容範囲と、チャック時およびリリース時を除いたとき、すなわち押し矢用サーボモータ74のみによって単にチェーン71を前後に駆動する通常の前後駆動のときに対応する押し矢用サーボモータ74の動作量の誤差の許容範囲である第2の許容範囲とが記憶されている。
第1の許容範囲は第2の許容範囲よりも大きく設定されている。
制御部94によるこの許容範囲の選択の切り替えは、具体的には、棒材供給装置50に対して出力される命令が、棒材200をチャックする動作に対応したものであるときや棒材200をリリースする動作に対応したものであるときに、第1の許容範囲を選択し、命令が、チャックする動作やリリースする動作に対応したもの以外のときに、第2の許容範囲を選択する。
そして、制御部94は、選択した第1の許容範囲または第2の許容範囲と前述した位置偏差(角度偏差)とを比較する。
このため、棒材200のチャック時やリリース時にエアシリンダ装置80がチェーン71を駆動すると、このチェーン71の駆動につられて押し矢用サーボモータ74が必要以上に回転することとなり、前述した位置偏差(角度偏差)が第2の許容範囲を逸脱し、制御部94は、押し矢用サーボモータ74の動作に誤差が生じたと判断して、その動作を停止させたり、表示部91に誤差過大エラーの表示をさせたりするおそれがある。
これにより、自動旋盤装置100の稼働率を向上させることができる。
この際、位置偏差の拡大に対応して押し矢用サーボモータ74の回転駆動電流が増加する。
制御部94は、押し矢用サーボモータ74の回転駆動電流が予め定められた限界値を超えると、エラーとして動作を停止させる。
第1の許容範囲が選択された場合に、電流規制手段を作動させることによって、押し矢用サーボモータ74に対する回転駆動電流は上述した所定値を超えることはない。
なお、前述した位置偏差が第1の許容範囲内となる範囲で押し矢用サーボモータ74が回転する際に、押し矢用サーボモータ74の回転駆動電流が前述の限界値を超えない場合は、必ずしも電流規制手段を作動させる必要はない。
本実施形態の自動旋盤装置100は、本発明における制御装置を、自動旋盤本体10に対する制御も行うNC制御装置90で兼用するものとした例であるが、本発明は、この例に限定されるものではなく、棒材供給装置専用の制御装置であってもよい。
このように棒材供給装置専用の制御装置を、棒材供給装置の構成として備えた棒材供給装置は、本発明の棒材供給装置の一例となる。
