Description
本考案は、主として工作機械の保護カバー、その他一般産業機械の保護カバーとして活用するものに関する。 The present invention mainly relates to a protective cover for machine tools and other industrial industrial machines.
直動する機械の動きに追従させ、回転ドラム2に巻き付けたシート1を巻き付けたり引き出したりしてストロークさせて使用する巻取りカバーに於いて、回転ドラムが回転しようとする力は、これまで回転ドラム内に設置したコイルバネ及びゼンマイバネをバネの巻き方向と同じ方向に回転させて捩る又は絞ることで回転させた方向とは逆方向に回転しようとする力を利用する事で回転ドラムが回転する力を得ていた。
巻取りカバーの主な用途である工作機械の保護カバーは、近年の著しい工作機械の大型化と高い稼働率に伴い、ロングストローク、高耐久性が必要とされる。回転ドラム内に施工したバネを用いた巻取りカバーのロングストロークの使用においては、バネの耐久性の問題で条件によっては早期に破損するといった問題があった。
The force that the rotating drum tries to rotate in the take-up cover that is used by following the movement of the linear machine and making the stroke by winding or pulling the sheet 1 wound around the rotating drum 2 rotates until now. The force to rotate the rotating drum by using the force to rotate the coil spring and the main spring installed in the drum in the opposite direction to the direction rotated by twisting or squeezing by rotating in the same direction as the winding direction of the spring Was getting.
Protective covers for machine tools, which are the main uses of winding covers, are required to have long strokes and high durability due to the recent significant increase in machine tool size and high operating rate. In the use of the long stroke of the winding cover using the spring installed in the rotating drum, there is a problem that the spring is damaged early due to a problem of durability of the spring.
近年の著しい工作機械の大型化と高い稼働率に伴い、巻取りカバーの主な用途である工作機械の保護カバーは、ロングストローク、高耐久性が必要とされる。その為、ロングストロークの使用に於いても高耐久性を持ったバネ或いはその他の方法で高い耐久性を有する巻取りカバーの開発が必要であった。 With the recent significant increase in machine tool size and high operating rate, the protection cover for machine tools, which is the main application of the winding cover, requires long strokes and high durability. Therefore, it has been necessary to develop a highly durable winding cover by using a spring having high durability or other methods even when using a long stroke.
本考案はかかる問題を解決するため鋭意研究し得られたもので、機械ドリブン式巻取りカバーに関するものであり、機械移動体8にボルト等で固定したシート3-1を回転ドラム5に巻きつけ、シート3-1とは逆回転でテンションシート3-2（シート状或いはひも状）を回転ドラム5に巻きつけ、更にシート3-1と対称になるように、同じく機械移動体8にボルト等で固定したシート4-1を回転ドラム6に巻きつけ、シート4-1とは逆回転でテンションシート4-2（シート状或いはひも状）を回転ドラム6に巻き付けると共にテンションシート3-2とテンションシート4-2の端部を張力部材7（金属又は樹脂或いは両者からなるバネ等）で連結することにより、回転ドラム5にE方向、回転ドラム6にF方向に回転する力を発生させてシート3-1,4-1に引っ張り力（テンション）を与えることで、機械移動体8の動きに追従してシート3-1,4-1を撓むことなく巻き付けたり引き出したりさせることで問題を解決している。 The present invention has been obtained through extensive research to solve such problems, and relates to a machine-driven winding cover. A sheet 3-1 fixed to a machine moving body 8 with a bolt or the like is wound around a rotating drum 5. The tension sheet 3-2 (sheet-like or string-like) is wound around the rotating drum 5 in the reverse direction to the sheet 3-1, and the machine moving body 8 is similarly bolted to be symmetrical with the sheet 3-1. The sheet 4-1 fixed in step 1 is wound around the rotating drum 6, and the tension sheet 4-2 (sheet-like or string-like) is wound around the rotating drum 6 in the reverse direction to the sheet 4-1, and the tension sheet 3-2 and tension are wound. By connecting the ends of the sheet 4-2 with a tension member 7 (metal or resin, or a spring made of both), the rotating drum 5 generates a force that rotates in the E direction and the rotating drum 6 rotates in the F direction. Apply tension to 3-1,4-1 In Rukoto, it solves the problem be to and withdraw or wound without flexing the sheet 3-1 and 4-1 to follow the movement of the machine moving body 8.
従来のバネの捻りによる力を利用した巻取りカバーでは回転ドラム2からシート1を引き出したり巻き戻したりしてストロークさせる際に、引き出すストロークが長くなるにつれて回転トルクが大きくなる為、回転トルクの原動力となるバネの疲労はストローク回数増加と共に大きくなり、やがて疲労限界に達するとバネは破損し巻取りカバーとして機能しなくなる。一方、本考案による巻取りカバー図4に於いては、機械が稼動する際の動力を利用して 機械移動体8がA方向へ移動した場合、シート3-1が回転ドラム5から引き出され回転ドラム5はB方向へ回転、そのときテンションシート3-2が回転ドラム5に巻取られC方向へ移動し。そのことによりテンションシート4-2が回転ドラム6から引き出され回転ドラム6はD方向へ回転、更にそのことでシート4-1が回転ドラム6に巻き取られ、従来のバネの捻りによる力を利用せずとも直動する機械の動きに追従する巻取りカバーとして機能した。
そのため、ストロークする際に、どの位置に於いてもほぼ同じ回転トルクを得ることができ、ロングストロークの使用に於いても安定した耐久性を得ることが可能となった。
In the conventional take-up cover that uses the force of spring twisting, when the sheet 1 is pulled out or rewound from the rotating drum 2 and stroked, the rotational torque increases as the pulling stroke becomes longer. The fatigue of the spring increases as the number of strokes increases, and when the fatigue limit is reached, the spring breaks and does not function as a winding cover. On the other hand, in the winding cover in FIG. 4 according to the present invention, when the machine moving body 8 moves in the direction A using the power when the machine is operated, the sheet 3-1 is pulled out from the rotating drum 5 and rotated. The drum 5 rotates in the B direction. At that time, the tension sheet 3-2 is wound around the rotating drum 5 and moves in the C direction. As a result, the tension sheet 4-2 is pulled out from the rotating drum 6, and the rotating drum 6 rotates in the D direction. Further, the sheet 4-1 is wound around the rotating drum 6 and uses the conventional spring twisting force. It functioned as a take-up cover that followed the movement of the machine that moved directly without it.
Therefore, it is possible to obtain substantially the same rotational torque at any position during a stroke, and it is possible to obtain a stable durability even when using a long stroke.
請求項1に記載の一般的な巻取りカバーに関する断面図を図1に示す。図2に本考案の主体となす機械ドリブン式巻取りカバーの斜視図を示す。 FIG. 1 shows a cross-sectional view of the general winding cover according to the first aspect. FIG. 2 shows a perspective view of a machine-driven wind-up cover that is the main body of the present invention.
図2の斜視図は請求項1に関するものであり、機械移動体8にボルト等で固定したシート3-1を回転ドラム5に巻きつけ、シート3-1とは逆回転でテンションシート3-2（シート状或いはひも状）を回転ドラム5に巻きつけ、更にシート3-1と対称になるように、同じく機械移動体8にボルト等で固定したシート4-1を回転ドラム6に巻きつけ、シート4-1とは逆回転でテンションシート4-2（シート状或いはひも状）を回転ドラム6に巻き付けると共にテンションシート3-2とテンションシート4-2の端部を張力部材7（金属又は樹脂或いは両者からなるバネ等）で連結することで機械ドリブン式巻取りカバーは構成される。 The perspective view of FIG. 2 relates to claim 1, and a sheet 3-1 fixed to the machine moving body 8 with a bolt or the like is wound around the rotating drum 5, and the tension sheet 3-2 is rotated in the reverse direction to the sheet 3-1. (Sheet or string) is wound around the rotating drum 5, and the sheet 4-1 fixed to the machine moving body 8 with a bolt or the like is also wound around the rotating drum 6 so as to be symmetrical with the sheet 3-1. The tension sheet 4-2 (sheet-like or string-like) is wound around the rotating drum 6 in the reverse direction to the sheet 4-1, and the end of the tension sheet 3-2 and the tension sheet 4-2 is attached to the tension member 7 (metal or resin). Alternatively, the mechanically driven winding cover is configured by connecting with a spring or the like comprising both.
テンションシート3-2とテンションシート4-2の端部に連結された張力部材7（金属又は樹脂或いは両者からなるバネ等）が回転ドラム5にE方向、回転ドラム6にF方向に回転する力を発生させてシート3-1,4-1に引っ張り力（テンション）を与え、機械移動体8の動きに追従してシート3-1,4-1を撓むことなく巻き付けたり引き出したりさせることにより、直動する機械の動きに追従する巻取りカバーとして機能する。 Force that tension member 7 (spring made of metal or resin or both) connected to the ends of tension sheet 3-2 and tension sheet 4-2 rotates in the E direction on rotating drum 5 and in the F direction on rotating drum 6 To generate a tension and apply tension to the sheets 3-1, 4-1 and follow the movement of the machine moving body 8 to wind or pull the sheets 3-1, 4-1 without bending. Thus, it functions as a winding cover that follows the movement of the machine that moves linearly.
