従来例として、特開平１０−２６３９８３号公報によればワークを搬入出する際にワークを案内する案内部を開閉カバーの一側面に設けたものが開示されている。カバーを開いた状態でワークシフト装置のアームの往復動作により、ワークをローラコンベアと加工機への搬送を行なう。このようにワークを搬入出するための専用のワークシフト装置を設け、大掛かりなワーク搬入出装置を必要としている。
特開平１０−２６３９８３号公報 As a conventional example, Japanese Patent Application Laid-Open No. 10-263993 discloses a structure in which a guide portion for guiding a workpiece when the workpiece is carried in and out is provided on one side surface of the opening / closing cover. The workpiece is transferred to the roller conveyor and the processing machine by the reciprocating motion of the arm of the workpiece shift device with the cover open. Thus, a dedicated work shift device for loading and unloading a workpiece is provided, and a large workpiece loading and unloading device is required.

その目的は、ワークをコンベア上から加工テーブルに搬入出する際には特別なワーク搬入出装置を設ける必要がなく、直接ワークをチャック機構で保持して開閉カバー装置を動作することでワークの搬入出を行なうことのできるようにするものである。 This invention was made paying attention to such problems existing in the prior art,
The purpose is that there is no need to install a special workpiece loading / unloading device when loading / unloading workpieces onto / from the processing table from the conveyor. It allows you to go out.

請求項１に記載の発明は、前方にワークを搬送する搬送装置を設けると共に、加工領域を囲う遮蔽カバーの一角にワークの搬出入を許容する開口部を設け、その開口部を塞ぐように開閉カバーが設けられた工作機械において、前記開閉カバーの加工領域側の側面に、ワークを保持するチャック機構を設け、開閉カバーを開いた時にコンベア上のワークを前記チャック機構でワークを保持して、前記開閉カバーを閉じることでワークを工作機械の加工テーブルに移動することを特徴とする工作機械の開閉カバー装置。 According to the first aspect of the present invention, a transport device that transports the workpiece is provided in the front, and an opening that allows the workpiece to be carried in and out is provided at one corner of the shielding cover that surrounds the processing area, and is opened and closed so as to close the opening. In a machine tool provided with a cover, a chuck mechanism for holding a workpiece is provided on the side of the opening / closing cover on the processing region side, and when the opening / closing cover is opened, the workpiece on the conveyor is held by the chuck mechanism, An opening / closing cover device for a machine tool, wherein the workpiece is moved to a machining table of a machine tool by closing the opening / closing cover.

請求項２に記載の発明は、前記工作機械のチャック機構を備えた開閉カバー装置は、前記搬送装置から未加工ワークを受け取り、前記加工テーブルへ移動する時は９０度回転して、加工済みワークを前記搬送装置に戻す時は１８０度回転することを要旨とする工作機械の開閉カバー装置。 According to a second aspect of the present invention, the open / close cover device including the chuck mechanism of the machine tool receives an unmachined workpiece from the transfer device, and rotates 90 degrees when moving to the machining table. An opening / closing cover device for a machine tool, which is rotated by 180 degrees when returning to the conveying device.

ワークを搬入出するための開口部に設けられた開閉カバーの加工領域側の側面に、ワークを保持するチャック機構を設け、ワークをチャック機構で保持した状態で、開閉カバーを開閉することでワークをコンベアから加工テーブルに移動できるから、ワークを搬入出するための専用のワーク搬入出装置が不要となりワーク搬入出装置が簡素化できる。 A chuck mechanism that holds the workpiece is provided on the side of the opening / closing cover provided in the opening for loading and unloading the workpiece, and the workpiece is opened and closed while the workpiece is held by the chuck mechanism. Can be moved from the conveyor to the processing table, a dedicated workpiece loading / unloading device for loading / unloading the workpiece is not required, and the workpiece loading / unloading device can be simplified.

請求項２によればワークをコンベアから加工テーブルに搬入する場合は、カバーを９０度回転して、ワークを搬出してコンベアに戻す場合は１８０度回転することで容易にワークの搬入出が可能となる。 According to claim 2, when the work is carried from the conveyor to the processing table, the cover is rotated 90 degrees, and when the work is carried out and returned to the conveyor, the work can be easily carried in and out by rotating 180 degrees. It becomes.

以下、本発明を以下に図面に基づいて説明する。
図１は工作機械１の同様な装置を３台並べた生産ラインとしての一例を示している。
夫々の工作機械１に備えた工具２により加工テーブル３に固定されたワークＷを加工するようになっている。
工作機械１は加工中の切屑の飛散を防止するための全体を取り囲む全体カバー４を夫々備えている。
その全体カバー４の右手前にはワークＷを加工テーブル３へ出し入れするための開口部５が設けられ、その一角にカバーの開閉を行なう開閉カバー６を設けている。
図２に開閉カバーの動作を説明している。開閉カバー６は直角を保ち二辺で構成して、加工領域側の側面にワークを保持するためのチャック機構としてのストッパ８とチャック機構９を備えている。二辺で構成したカバーの交点に回転支軸７を備え図示しないモータの駆動によって回転するようになっている。
工作機械１の手前には左右にわたりワークＷを搬送するためのコンベア装置１０を備えている。
未加工ワークを図１の左側から搬送されて、最初に左側に配置した工作機械１による加工がなされ、次いで順に中央に配置した工作機械１により順次加工するようになっている。 The present invention will be described below with reference to the drawings.
FIG. 1 shows an example of a production line in which three similar devices of a machine tool 1 are arranged.
The workpiece W fixed to the machining table 3 is machined by a tool 2 provided in each machine tool 1.
The machine tool 1 is provided with a whole cover 4 that surrounds the whole for preventing scattering of chips during machining.
An opening 5 for taking the workpiece W into and out of the processing table 3 is provided in front of the entire cover 4, and an opening / closing cover 6 for opening and closing the cover is provided at one corner.
FIG. 2 illustrates the operation of the opening / closing cover. The opening / closing cover 6 is formed of two sides while maintaining a right angle, and is provided with a stopper 8 and a chuck mechanism 9 as a chuck mechanism for holding the workpiece on the side surface on the processing area side. A rotation support shaft 7 is provided at the intersection of the cover constituted by two sides and is rotated by driving a motor (not shown).
In front of the machine tool 1, a conveyor device 10 for conveying the workpiece W across the left and right is provided.
An unmachined workpiece is conveyed from the left side of FIG. 1 and is first processed by the machine tool 1 arranged on the left side, and then sequentially processed by the machine tool 1 arranged in the center in order.

次ぎにワークＷの搬入作用について図２で説明する。
未加工ワークＷがコンベア装置１０の左側から搬入されることになるが、ワークの加工中の開閉カバー６は図（ａ）の状態となっている。続いて開閉カバー６が図示しないモータを駆動源にして９０度開いた状態にして待機する。次いでコンベア装置１０に搬送されてくるワークＷを図（ｂ）のようにストッパ８で受けとめチャック機構９で図略のチャック駆動機構によりワークを挟み込み図（ｃ）のように保持するようになっている。
次ぎに開閉カバー６は閉じて図（ｄ）のようにしてワークＷを加工テーブル３上に移載される。加工テーブル３上の公知のワーク固定治具によりワークＷ固定して加工が開始される。
加工が完了すると加工テーブル３上のワークＷは再び図（ｄ）の右下の所定の受渡し位置に移動する。ワークＷは開閉カバー６に取り付けられたチャック機構９により保持される。
次ぎに開閉カバー６が開き１８０度回転して、図（ｅ）のようにワークＷをコンベア１０上に移動搬出して、チャック機構９がワークを開放する。 Next, the loading operation of the workpiece W will be described with reference to FIG.
Although the unprocessed workpiece W is carried in from the left side of the conveyor apparatus 10, the open / close cover 6 during processing of the workpiece is in the state shown in FIG. Subsequently, the open / close cover 6 is opened by 90 degrees using a motor (not shown) as a drive source and waits. Next, the workpiece W conveyed to the conveyor device 10 is received by the stopper 8 as shown in FIG. 2B, and the workpiece is sandwiched by the chuck drive mechanism 9 (not shown) and held as shown in FIG. Yes.
Next, the opening / closing cover 6 is closed and the workpiece W is transferred onto the processing table 3 as shown in FIG. Processing is started by fixing the workpiece W by a known workpiece fixing jig on the processing table 3.
When the machining is completed, the workpiece W on the machining table 3 moves again to the predetermined delivery position at the lower right in FIG. The workpiece W is held by a chuck mechanism 9 attached to the opening / closing cover 6.
Next, the opening / closing cover 6 is opened and rotated 180 degrees to move and carry the workpiece W onto the conveyor 10 as shown in FIG. 5E, and the chuck mechanism 9 releases the workpiece.

本発明では工作機械１をワーク搬送するコンベアの正面に配置したが、図３のように複数の工作機械１をコンベアの横向きに配置しても同様な効果を得ることができる。 In the present invention, the machine tool 1 is arranged in front of the conveyor that conveys the workpiece, but the same effect can be obtained even if a plurality of machine tools 1 are arranged in the lateral direction of the conveyor as shown in FIG.
