Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 is a view showing a machine tool 100 equipped with a chip collection device 10 according to an embodiment of the present invention. First, the machine tool 100 on which the chip collection device 10 is mounted will be described, and then the chip collection device 10 will be described.
The machine tool 100 includes a processing means 110 for cutting the work W in order to process the work W made of metal, a driving means 120 for driving the processing means 110, and a main body case 130 containing the driving means 120. It is equipped with.

加工手段110は、例えば金型等のワークWの切削加工を行なう装置であって図に示すように切刃111などの切削工具を備えている。この加工手段110によって切削加工が施されるワークWは、例えば加工手段110の下方に配置されたテーブル140に載置される。   The processing means 110 is a device for cutting a workpiece W such as a die, for example, and includes a cutting tool such as a cutting edge 111 as shown in the drawing. The workpiece W to be cut by the processing means 110 is placed on a table 140 disposed below the processing means 110, for example.

駆動手段120は、例えばモータであって、このモータの回転力を切刃111に伝達して切刃111を回転させる。   The driving means 120 is, for example, a motor, and transmits the rotational force of the motor to the cutting blade 111 to rotate the cutting blade 111.

本体ケース130は、上記のテーブル140の上方で駆動手段120の全体を覆う筐体であり、ケース底面には例えばモータの回転軸(図示省略)がテーブル側へ向けて突出するように貫通穴(図示省略)が形成されている。この貫通穴から突き出た回転軸に加工手段110の切刃111が直接或いは他の部材を介して取り付けられている。

In addition, the machine tool 100 may be one in which the position of the processing means 110 is fixed. In this case, the work W is moved and the work W is cut.

次に、切粉回収装置10について説明する。
この切粉回収装置10は、工作機械100におけるワーク加工時に生ずる切粉D(図2参照)を回収するものであり、切粉Dを吸着する磁気手段20と、磁気手段20に付着した切粉を吸引する吸引手段30と、磁気手段20を加工手段110の傍らから吸引手段30まで移動させる移動手段40と、を備えている。
Next, the chip collection device 10 will be described.
The chip collection device 10 collects the chip D (see FIG. 2) generated when the workpiece is machined in the machine tool 100. The chip 20 adsorbs the chip D and the chip adhered to the magnetic unit 20. And a moving means 40 for moving the magnetic means 20 from the side of the processing means 110 to the attraction means 30.

磁気手段20は、ワークWを切削して生ずる金属の切粉Dを吸着するものであり、例えば、磁石21とこの磁石21を保持する非磁性体で成るホルダー22とから構成される。ホルダー22は、磁石21の一部が露呈するように磁石21を把持し或いは磁石21の全体を覆うようにボックス状に形成されてもよい。本発明において、磁気手段20はホルダー22を用いずに構成されてもよい。   The magnetic means 20 attracts metal chips D generated by cutting the workpiece W, and includes, for example, a magnet 21 and a holder 22 made of a non-magnetic material that holds the magnet 21. The holder 22 may be formed in a box shape so as to hold the magnet 21 so that a part of the magnet 21 is exposed or to cover the entire magnet 21. In the present invention, the magnetic means 20 may be configured without using the holder 22.

吸引手段30は、磁気手段20に付着した切粉Dを吸引するものであり、切粉Dを輸送する切粉用管31と、切粉用管31内に負圧を発生させる負圧発生装置(図示省略)と、を備えている。なお、図面では切粉用管31を断面形状で表している。
切粉用管31は、例えばバキュームホースであり、先端の吸引口に磁気手段20を囲繞するカップ状の囲繞部材32が設けられている。この囲繞部材32は、切粉用管31と一体に製造されたものや、別体で作られたものを切粉用管31に取り付けて一体にしたものでもよい。なお、本実施形態では、この囲繞部材32は、図1に示すように、工作機械100の本体ケース130の側面に設けたガイド部材131に固定されている。具体的には、本体ケース130の側面から水平方向へ突出した、例えばブロック状のガイド部材131の底面に、囲繞部材32は下方のテーブル140側に開口32Aが臨むように取り付けられている。また、この囲繞部材32で囲われるカップ内部S1と切粉用管の内部S2とは、囲繞部材32の側面に開設した穴32Bを介して連通している。なお、図面では囲繞部材32を断面形状で表している。
The suction means 30 sucks the chips D adhering to the magnetic means 20, and includes a chip 31 for transporting the chips D, and a negative pressure generator for generating a negative pressure in the chip 31. (Not shown). In the drawings, the chip tube 31 is represented by a cross-sectional shape.
The chip tube 31 is, for example, a vacuum hose, and a cup-shaped surrounding member 32 that surrounds the magnetic means 20 is provided at the suction port at the tip. The surrounding member 32 may be manufactured integrally with the chip 31 or may be integrally formed by attaching a separate one to the chip 31. In the present embodiment, the surrounding member 32 is fixed to a guide member 131 provided on the side surface of the main body case 130 of the machine tool 100 as shown in FIG. Specifically, the surrounding member 32 is attached to the bottom surface of, for example, a block-shaped guide member 131 protruding from the side surface of the main body case 130 so that the opening 32A faces the lower table 140 side. In addition, the cup interior S1 surrounded by the surrounding member 32 and the interior S2 of the chip for chips are communicated with each other through a hole 32B opened on the side surface of the surrounding member 32. In the drawing, the surrounding member 32 is represented by a cross-sectional shape.

移動手段40は、ワークWの加工を施す加工手段110の傍ら、図示例の切刃111では刃先の近傍(位置P1)から前述の囲繞部材32内(位置P2)へ磁気手段20を移動させるものである。
ここで、本発明におけるワークWの加工を施す加工手段110の傍ら(近傍)とは、例えば、加工手段110がワークWに接触するポイント(位置P0)を中心として、切削加工によって生じる切粉Dが集中してテーブル面上及びワーク面上に落ちる半径R(R=0mm〜300mm程度)の水平な領域であって、切刃111の場合刃先を基準に上下方向の高さH(H=−300mm〜300mm程度)の領域を言い、この領域内の所定の位置、具体的には本実施形態では位置P1で磁気手段20は切粉Dを収集する。即ち、磁気手段20は、移動手段40によって切粉Dが集中してテーブル面上及びワーク面上に落ちる加工手段の近傍(位置P1)の位置に保持された状態で、切粉Dを吸着させることを特徴としている。
The moving means 40 moves the magnetic means 20 from the vicinity of the cutting edge 111 (position P1) to the inside of the surrounding member 32 (position P2) in the illustrated cutting blade 111 in addition to the processing means 110 that processes the workpiece W. It is.
Here, the side (near) of the processing means 110 that performs the processing of the workpiece W in the present invention is, for example, a chip D generated by cutting processing around a point (position P0) at which the processing means 110 contacts the workpiece W. Is a horizontal region having a radius R (R = 0 to 300 mm) that concentrates on the table surface and the workpiece surface, and in the case of the cutting blade 111, the height H (H = − The magnetic means 20 collects the chips D at a predetermined position in this area, specifically, at the position P1 in this embodiment. That is, the magnetic means 20 attracts the chips D while the chips D are held by the moving means 40 at a position (position P1) in the vicinity of the processing means that falls on the table surface and the work surface. It is characterized by that.

このため、移動手段40は、例えば本体ケース130に添設されたシリンダー装置で成り、シリンダー本体41と、シリンダー本体41に進退可能なロッド42と、を備えている。このロッド42の先端部に、前述の磁気手段20が取り付けられている。そして、磁気手段20を位置P1から位置P2へ移動させるために、ロッド42が囲繞部材32及びガイド部材131を貫通して鉛直方向に沿ってストロークするように、移動手段40は本体ケース130に取り付けられている。なお、シリンダー本体41から引き出されるロッド42のストロークをガイドするように、シリンダー本体41の下面にはテーブル方向へ延出した筒状のガイド43が設けられている。   For this reason, the moving means 40 is composed of, for example, a cylinder device attached to the main body case 130, and includes a cylinder main body 41 and a rod 42 that can move forward and backward with respect to the cylinder main body 41. The magnetic means 20 is attached to the tip of the rod 42. Then, in order to move the magnetic means 20 from the position P1 to the position P2, the moving means 40 is attached to the main body case 130 so that the rod 42 strokes along the vertical direction through the surrounding member 32 and the guide member 131. It has been. A cylindrical guide 43 extending in the table direction is provided on the lower surface of the cylinder body 41 so as to guide the stroke of the rod 42 drawn from the cylinder body 41.

このように構成された本発明の切粉回収装置10を搭載した工作機械100によれば、ワークWの加工処理時には、図2(A)に示すように、移動手段40によって磁気手段20を位置P1に保持した状態で、工作機械100を動作させてワークWを加工する。
この切削加工の際、ワークWを切削して生じる切粉Dは、磁石21の磁力によって磁気手段20の表面に付着する。
According to the machine tool 100 equipped with the chip recovery apparatus 10 of the present invention configured as described above, when the workpiece W is processed, the magnetic means 20 is positioned by the moving means 40 as shown in FIG. In a state where it is held at P1, the machine tool 100 is operated to process the workpiece W.
In this cutting process, the chips D generated by cutting the workpiece W adhere to the surface of the magnetic means 20 by the magnetic force of the magnet 21.

そして、移動手段40によってロッド42をストロークさせて、図2(B)に示すように磁気手段20を位置P2へ移動させる。磁気手段20が囲繞部材32で覆われた状態で、吸引手段30によって切粉用管31内に負圧を発生させると、囲繞部材32内の空気が切粉用管31内に引き込まれる。この吸引力が、切粉Dを磁気部材表面で保持する磁力より強くなると、切粉Dが磁気部材表面から外れて切粉用管31内に吸収され、この切粉用管31によって例えば図示省略する回収ボックスへ案内される。   Then, the rod 42 is stroked by the moving means 40, and the magnetic means 20 is moved to the position P2 as shown in FIG. When negative pressure is generated in the chip 31 by the suction means 30 in a state where the magnetic unit 20 is covered with the surrounding member 32, the air in the surrounding member 32 is drawn into the chip 31. When this suction force becomes stronger than the magnetic force that holds the chip D on the surface of the magnetic member, the chip D is detached from the surface of the magnetic member and absorbed into the chip tube 31. To the collection box.

このように、本発明の実施形態に係る切粉回収装置10によれば、ワークWから切粉Dが生ずる発生源(前述の位置P0)に近接した位置P1で切粉Dを収集し、工作機械100から離れた位置に設けられた回収ボックス(図示省略)へ通じる切粉用管31の先端口付近へ収集した切粉Dを移動手段40によって移動させて、切粉用管31内の負圧で吸引して、回収ボックスに移動させる。
従って、本実施形態の切粉回収装置10は、工作機械100を大型化させることなく、切削加工によって生じた切粉Dを回収することができる。また、ワークWの一部だけを加工する場合に生じる切粉Dも、大掛かりな構成を必要とせずに効果的に回収することができる。
Thus, according to the chip recovery apparatus 10 according to the embodiment of the present invention, the chip D is collected at the position P1 close to the generation source (the above-described position P0) where the chip D is generated from the workpiece W, The chips D collected near the tip of the chip tube 31 leading to a collection box (not shown) provided at a position away from the machine 100 are moved by the moving means 40, and the negative in the chip tube 31 is moved. Aspirate with pressure and move to collection box.
Therefore, the chip collection device 10 of the present embodiment can collect the chip D generated by the cutting process without increasing the size of the machine tool 100. Further, the chips D generated when only a part of the workpiece W is processed can be effectively recovered without requiring a large-scale configuration.

次に、図3(A)及び(B)は、本発明の他の実施形態に係る切粉回収装置10Aを示すもので、この切粉回収装置10Aは、前述の切粉回収装置10と異なり、磁気手段20Aは、移動手段40のロッド42の直径と同じ直径の円柱形状に形成されていることを特徴としている。このような構成により、ロッド42の先端部に磁気手段20Aが取り付けられた状態では、ロッド42は、本来の長さより磁気手段20Aの長さ分だけ延長した、長さ方向全体に亘って一定の断面を有する棒の形態を成す。ガイド部材131の貫通孔131Aはこのロッド42を摺動させるようにその穴の大きさが選定されており、さらに移動手段40によって磁気手段20Aが持ち上げられた状態で磁気手段20Aがガイド部材131の貫通孔131A内に位置するように、ロッド42の長さが選定されている。
このような切粉回収装置10Aによれば、位置P1で磁気手段20Aに付着した切粉Dは、移動手段40によってロッド42が持ち上げられて磁気手段20Aがガイド部材131内に入り込む際、貫通孔131Aの縁によってそぎ落とされる。このようにして、切粉Dが磁気手段20Aから外れた際に切粉用管31内に負圧を発生させることで、切粉Dを切粉用管31内に吸引して、図示省略する回収ボックスへ移動させることができる。したがって、切粉回収装置10Aは、切粉回収装置10に比べて、磁石で収集した切粉Dを確実に回収することができる。
Next, FIGS. 3A and 3B show a chip collection apparatus 10A according to another embodiment of the present invention. This chip collection apparatus 10A is different from the chip collection apparatus 10 described above. The magnetic means 20A is characterized by being formed in a cylindrical shape having the same diameter as the diameter of the rod 42 of the moving means 40. With such a configuration, in a state in which the magnetic means 20A is attached to the tip of the rod 42, the rod 42 has a certain length over the entire length direction, which is extended from the original length by the length of the magnetic means 20A. In the form of a bar with a cross section. The size of the hole of the through hole 131A of the guide member 131 is selected so that the rod 42 is slid, and the magnetic means 20A is lifted by the moving means 40 while the magnetic means 20A is lifted by the guide member 131. The length of the rod 42 is selected so as to be located in the through hole 131A.
According to such a chip recovery apparatus 10A, the chip D adhering to the magnetic means 20A at the position P1 passes through the hole when the rod 42 is lifted by the moving means 40 and the magnetic means 20A enters the guide member 131. It is scraped off by the edge of 131A. In this way, when the chip D is removed from the magnetic means 20A, a negative pressure is generated in the chip tube 31 so that the chip D is sucked into the chip tube 31 and is not shown. It can be moved to the collection box. Therefore, the chip collection device 10 </ b> A can reliably collect the chip D collected by the magnet as compared with the chip collection device 10.

次に、図4(A)〜(C)は、本発明のさらに他の実施形態に係る切粉回収装置10Bを示すもので、この切粉回収装置10Bは、前述の切粉回収装置10Aと異なり、磁気手段20Bが磁気手段20Aより長い棒状磁石で構成されていることを特徴としている。この実施形態に係る切粉回収装置10Bでは、前述の実施形態の移動手段40に代えて、移動手段40Aを備えている。この移動手段40Aは、シリンダー本体41と、シリンダー本体41に進退可能なロッド42Aと、を備えている。   Next, FIGS. 4A to 4C show a chip collection apparatus 10B according to still another embodiment of the present invention. This chip collection apparatus 10B includes the above-described chip collection apparatus 10A. Unlike the magnetic means 20B, the magnetic means 20B is composed of a bar magnet longer than the magnetic means 20A. The chip collection apparatus 10B according to this embodiment includes a moving unit 40A instead of the moving unit 40 of the above-described embodiment. The moving means 40 </ b> A includes a cylinder body 41 and a rod 42 </ b> A that can move forward and backward with respect to the cylinder body 41.

この実施形態では、図4(A)に示すように、ロッド42Aがシリンダー本体41から最も引き出された状態でロッド42Aの先端部421はガイド部材131の上方に位置し、このロッド先端部421に棒磁石で成る磁気手段20Bがガイド部材131の貫通孔131A及び囲繞部材32の貫通孔32Cを通過して、加工手段110の傍らで上下方向へ延出するように、磁気手段20Bの長さは選定されて、ロッド42Aに取り付けられている。この場合、例えば、前述した『加工手段110の傍ら』の領域を上下に亘って棒状の磁石、即ち磁気手段20Bが、切粉回収時に配置されるように、その寸法を設定するのが望ましい。また、磁気手段20Bがロッド42Aによって最上位置へ持ち上げられた状態で、図4(C)に示すように、磁気手段20Bの下端、即ち棒磁石の下端がガイド部材131の貫通孔131A内に位置するように長さなどを調節する。   In this embodiment, as shown in FIG. 4 (A), the rod 42A is located at the uppermost position of the guide member 131 in a state in which the rod 42A is most pulled out from the cylinder body 41. The length of the magnetic means 20B is such that the magnetic means 20B made of a bar magnet passes through the through hole 131A of the guide member 131 and the through hole 32C of the surrounding member 32 and extends vertically by the processing means 110. Selected and attached to rod 42A. In this case, for example, it is desirable to set the dimensions so that the bar-like magnet, that is, the magnetic means 20B is arranged at the time of chip collection over the above-mentioned "beside the processing means 110" region. Further, in a state where the magnetic means 20B is lifted to the uppermost position by the rod 42A, the lower end of the magnetic means 20B, that is, the lower end of the bar magnet is positioned in the through hole 131A of the guide member 131 as shown in FIG. Adjust the length and so on.

この磁気手段20Bの断面形状は、円形及び四角形に限るものではなく、この磁気手段20Bが貫通するガイド部材131の貫通孔131A及び囲繞部材32の貫通孔32Cと同形であればよい。より好ましくは、磁気手段20Bがガイド部材131の貫通孔131A及び囲繞部材32の貫通孔32Cに対して摺動するように、磁気手段20Bの断面形状がガイド部材131の貫通孔131A及び囲繞部材32の貫通孔32Cの穴の形状とほぼ一致するのが望ましい。   The cross-sectional shape of the magnetic means 20B is not limited to a circle and a quadrangle, and may be the same shape as the through hole 131A of the guide member 131 and the through hole 32C of the surrounding member 32 through which the magnetic means 20B passes. More preferably, the cross-sectional shape of the magnetic means 20B is such that the magnetic means 20B slides with respect to the through hole 131A of the guide member 131 and the through hole 32C of the surrounding member 32. It is desirable to substantially match the shape of the through-hole 32C.

このような切粉回収装置10Bによれば、切粉回収装置10Aと同様に、図4(B)に示すように切粉回収時に加工手段110の傍らに配置された磁気手段20Bによって収集した切粉Dは、移動手段40によってロッド42Aが持ち上げられて磁気手段20Bがガイド部材131内に入り込む際、ガイド部材131や囲繞部材32の貫通孔131A、32Cの縁に棒磁石(即ち磁気手段20B)の表面からそぎ落とされる。このようにして、切粉Dが磁気手段20Bから外れた際に切粉用管31内に負圧を発生させることで、切粉Dを切粉用管31内に吸引して、図示省略する回収ボックスへ回収させることができる。   According to such a chip recovery apparatus 10B, as with the chip recovery apparatus 10A, the chips collected by the magnetic means 20B disposed beside the processing means 110 during chip recovery as shown in FIG. 4B. When the rod 42A is lifted by the moving means 40 and the magnetic means 20B enters the guide member 131, the powder D is a bar magnet (that is, the magnetic means 20B) at the edges of the through holes 131A and 32C of the guide member 131 and the surrounding member 32. It is scraped off from the surface. In this way, when the chip D is removed from the magnetic means 20B, negative pressure is generated in the chip 31 to suck the chip D into the chip 31 and the illustration is omitted. It can be collected in a collection box.

したがって、切粉回収装置10Bは、切粉回収装置10Aに比べて、工作機械100で生ずる大量の切粉Dを確実に回収することができる。即ち、切粉回収装置10Bによれば、磁気手段20Bが『加工手段110の傍ら』の領域を上下に亘って配置された状態で切粉Dを回収するため切粉回収装置10Aに比べて切粉Dの回収率を格段に向上することができる。よって、本実施形態の切粉回収装置10Bによれば、前述の切粉回収装置10,10Aよりも効果的に切粉Dを回収できる。   Therefore, the chip collection device 10B can reliably collect a large amount of the chips D generated in the machine tool 100 as compared with the chip collection device 10A. That is, according to the chip collection device 10B, the magnetic means 20B collects the chip D in a state where the magnetic means 20B is arranged in the upper and lower regions, and cuts the chip D compared with the chip collection device 10A. The recovery rate of the powder D can be significantly improved. Therefore, according to the chip collection apparatus 10B of this embodiment, the chip D can be collected more effectively than the above-described chip collection apparatuses 10 and 10A.
