Abstract

In a magnetism separation/recovery device, a moving body (120) is rotated by movement of a magnetic substance-containing liquid (1) introduced into an annular flow path (110) from a flow path (112) for introducing the magnetic substance-containing liquid. Swarf (1B) in the magnetic substance-containing liquid (1) is attracted to the circular cylinder-like drum (122) side by a permanent magnet (130) provided in a predetermined region on the inner peripheral surface of the moving body (120) and carried in that state as the moving body (120) rotates. A cutting fluid (1A) from which the swarf (1B) is separated is discharged outside from a cutting liquid- discharging flow path (114). Because the swarf (1B) carried with the rotation of the moving body (120) passes through a magnetic region (MA), a magnetic force from a magnetic member (130) does not act on the swarf (1B) and the swarf (1B) passes a magnetic substance-discharging flow path (116) by free fall and is recovered into a magnetic body recovery box (118). The magnetism separation/recovery device can separate and recover magnetic substances such as swarf and metal powder contained in a liquid without drive power or with reduced power, and with magnetism.

発明の効果  The invention's effect
[0020] この発明に基づいた磁気分離回収装置のある局面によれば、回転運動に基づき、 磁力を用 ヽて液体中に含まれる磁性体を所定方向に移動させることにより磁性体を 回収して、液体中から磁性体を分離するための分離手段を備えるが、上記回転運動 は、磁性体含有液体の移動によるエネルギを回転エネルギに変換する変換手段によ り得ることを可能とする構成を備えることにより、従来のような、電動機等による駆動装 置を不要とするか、または、補助駆動装置のみによる駆動を可能にする。これにより、 搬送機構および装置の複雑化、並びに、装置の大型化を回避することが可能となる  According to one aspect of the magnetic separation and recovery apparatus based on the present invention, the magnetic material is recovered by moving the magnetic material contained in the liquid in a predetermined direction using a magnetic force based on the rotational motion. And a separating means for separating the magnetic substance from the liquid, but a structure is provided in which the rotational motion can be obtained by a converting means for converting energy due to the movement of the magnetic substance-containing liquid into rotational energy. This eliminates the need for a conventional driving device such as an electric motor, or enables driving using only an auxiliary driving device. This makes it possible to avoid complication of the transport mechanism and the device and increase in the size of the device.
[0021] また、この発明に基づいた磁気分離回収装置の他の形態によれば、流路内に磁性 体含有液体を流すことにより、まず、磁性体含有液体に含まれる磁性体は、磁気領 域において、磁気部材力 の磁力に引付けられる。ここで、流路の内側には移動体 が設けられているため、磁性体は磁気部材カもの磁力の着磁力に基づき、見かけ上 移動体上に磁着された状態となる。磁気領域には、流路から分岐する液体流路が設 けられて ヽることから、磁性体含有液体から磁性体が分離された液体はこの液体流 路から、外部に排出される。 Further, according to another embodiment of the magnetic separation and recovery apparatus based on the present invention, the magnetic substance contained in the magnetic substance-containing liquid is first removed by flowing the magnetic substance-containing liquid in the flow path. In the region, it is attracted to the magnetic force of the magnetic member force. Here, since the moving body is provided inside the flow path, the magnetic body is apparently magnetized on the moving body based on the magnetizing force of the magnetic force of the magnetic member. Since the liquid flow path branched from the flow path is provided in the magnetic region, the liquid in which the magnetic substance is separated from the magnetic substance-containing liquid is discharged to the outside from this liquid flow path.
[0022] 一方、磁性体は移動体とともに移動するが、磁気領域を通過した後には、磁性体に は、磁気部材からの磁力が及ばなくなる。磁気領域を通過した領域（下流側）には、 磁性体回収領域が設けられていることから、磁力が及ばなくなった磁性体は、この磁 性体回収領域に集められることになる。このようにして、磁気部材からの磁力を用い て、液体と磁性体とを分離するとともに、磁気部材からの磁力が及ばなくなることを積 極的に利用して、磁性体を所定位置に回収することを可能として 、る。 On the other hand, the magnetic body moves together with the moving body, but after passing through the magnetic region, the magnetic force from the magnetic member does not reach the magnetic body. In the area (downstream side) that has passed the magnetic area, Since the magnetic material recovery region is provided, the magnetic material that has stopped reaching the magnetic force is collected in the magnetic material recovery region. In this manner, the liquid and the magnetic material are separated by using the magnetic force from the magnetic member, and the magnetic material is recovered to a predetermined position by actively utilizing the fact that the magnetic force from the magnetic member does not reach. As possible.
[0023] また、上記流路を環状流路とし、上記移動体を磁性体含有液体が流れる方向に沿 つて回転可能に設け、上記環状流路の最頂部から回転方向にずれた位置に導入流 路を設けることにより、磁性体含有液体の移動によるエネルギを用いて、移動体を回 転させることができる。その結果、分離された磁性体を磁性体回収領域に導く場合に おいても、外部動力を必要とせず、装置構成の簡略化、および小型化を図ることを可 能とする。  [0023] Further, the flow path is an annular flow path, and the moving body is provided rotatably in a direction in which the magnetic substance-containing liquid flows, and the introduction flow is shifted from the top of the annular flow path in the rotational direction. By providing the path, the moving body can be rotated using the energy generated by the movement of the magnetic substance-containing liquid. As a result, even when the separated magnetic material is guided to the magnetic material collection area, external power is not required, and the configuration of the device can be simplified and the size can be reduced.
[0024] また、この発明に基づ 、た磁気分離回収装置の他の形態によれば、マグネットカバ 一の表面に螺旋磁気部材からの磁力により磁着した磁性体は、螺旋状に配置される 螺旋磁気部材とマグネットカバーとを相対的に軸周りに回転させることにより、螺旋状 に所定の軸方向に搬送されることになる。その結果、送り方向の先端部においては、 最終的には、螺旋磁気部材力 の磁力が及ばなくなる結果、マグネットカバーの表面 から磁性体が剥がれ、分離手段の軸方向先端側に、磁性体含有液体から分離され た磁性体を回収することが可能となる。その結果、上下方向への磁性体含有液体の 落下距離を小さくすることが可能となるため、磁気分離回収装置の高さ方向の小型 化を図ることが可能になる。  According to another aspect of the magnetic separation and recovery apparatus based on the present invention, the magnetic body magnetically attached to the surface of the magnet cover by the magnetic force from the spiral magnetic member is arranged in a spiral shape. By rotating the spiral magnetic member and the magnet cover relatively around the axis, the spiral magnetic member is spirally conveyed in a predetermined axial direction. As a result, at the leading end in the feed direction, the magnetic force of the helical magnetic member force eventually stops reaching, so that the magnetic body is peeled off from the surface of the magnet cover, and the magnetic body-containing liquid is placed on the leading end side in the axial direction of the separating means. It is possible to recover the magnetic material separated from the magnetic material. As a result, it is possible to reduce the falling distance of the magnetic substance-containing liquid in the vertical direction, so that the height of the magnetic separation and recovery apparatus can be reduced.
[0025] この発明に基づいた磁気分離回収装置の他の局面によれば、簡易な機構により、 磁気を用いて流体中に含まれる切屑等の磁性体を流体中から積極的に分離回収す るとともに、装置構成と磁力との関係を最適化することで効果的に磁性体を流体中か ら分離回収することを可能とする。  [0025] According to another aspect of the magnetic separation and recovery device based on the present invention, a magnetic material such as chips contained in the fluid is positively separated and recovered from the fluid by using a simple magnetism. In addition, by optimizing the relationship between the device configuration and the magnetic force, it becomes possible to effectively separate and collect the magnetic material from the fluid.

[0029] (実施の形態 1)  (Embodiment 1)
まず、図 1から図 4A, Bを参照して、実施の形態 1における磁気分離回収装置につ いて説明する。  First, a magnetic separation and recovery apparatus according to Embodiment 1 will be described with reference to FIGS. 1 to 4A and 4B.
[0030] (装置構成）  [0030] (Device configuration)
まず、図 1を参照して、本実施の形態における磁気分離回収装置 100の装置構成 について説明する。この磁気分離回収装置 100は、循環させて用いられる切削液に 切屑等の磁性体が含まれた磁性体含有液体 1から、磁性体を分離回収するためのも のであり、側面から見た場合円形の環状流路 110を有している。この環状流路 110 は、ドラム形状の筐体 113の内周面と、この筐体 113の内部において、回転可能に 配設される円筒状ドラム 122の外周面とによって規定される。円筒状ドラム 122は、そ の軸を中心として回転するように筐体 113に係合される。円筒状ドラム 122の外周面 には、環状流路 110内において放射状に延びる水受羽根 124が、所定のピッチで複 数配置されている。本実施の形態においては、円筒状ドラム 122および水受羽根 12 4により移動体 120を構成し、また、円筒状ドラム 122の外周面力 環状流路 110の 内側壁を構成する。また、円筒状ドラム 122および水受羽根 124は、榭脂材料その 他の非磁性体物質から構成される。なお、水受羽根 124の詳細構造については後 述する。 First, the configuration of the magnetic separation and recovery apparatus 100 according to the present embodiment will be described with reference to FIG. This magnetic separation and recovery device 100 is used to circulate cutting fluid. This is for separating and recovering a magnetic substance from the magnetic substance-containing liquid 1 containing a magnetic substance such as chips, and has a circular annular flow channel 110 when viewed from the side. The annular flow passage 110 is defined by an inner peripheral surface of a drum-shaped housing 113 and an outer peripheral surface of a cylindrical drum 122 rotatably disposed inside the housing 113. The cylindrical drum 122 is engaged with the housing 113 so as to rotate about its axis. On the outer peripheral surface of the cylindrical drum 122, a plurality of water receiving blades 124 extending radially in the annular flow path 110 are arranged at a predetermined pitch. In the present embodiment, the moving body 120 is constituted by the cylindrical drum 122 and the water receiving blade 124, and the inner wall of the annular flow path 110 is formed by the outer peripheral surface force of the cylindrical drum 122. The cylindrical drum 122 and the water receiving blade 124 are made of a resin material or other non-magnetic substance. The detailed structure of the water receiving blade 124 will be described later.
[0031] 環状流路 110の最頂部から円筒状ドラム 122の回転方向（図中の時計回転方向） にずれた位置には、環状流路 110に磁性体含有液体 1を導入するための磁性体含 有液体導入流路 112が連結されている。ここで、磁性体含有液体導入流路 112を環 状流路 110の最頂部力もずれた位置に設けているのは、円筒状ドラム 122の回転方 向を一定方向にするためである。したがって、他の手段により円筒状ドラム 122の回 転方向を一方向に規制する場合には、磁性体含有液体導入流路 112を環状流路 1 10の最頂部を含むように設けることも可能である。  A magnetic substance for introducing the magnetic substance-containing liquid 1 into the annular flow path 110 is provided at a position shifted from the top of the annular flow path 110 in the rotation direction of the cylindrical drum 122 (clockwise direction in the figure). The containing liquid introduction channel 112 is connected. Here, the reason why the magnetic substance-containing liquid introduction flow channel 112 is provided at a position where the highest force of the annular flow channel 110 is also shifted is to make the rotation direction of the cylindrical drum 122 constant. Therefore, in the case where the rotation direction of the cylindrical drum 122 is restricted to one direction by other means, the magnetic substance-containing liquid introduction flow path 112 may be provided so as to include the top of the annular flow path 110. is there.
[0032] 環状流路 110の最下端部を含む領域には、磁性体含有液体 1から切屑（磁性体） 1 Bが分離された切削液 (液体） 1Aを導くための切削液排出流路 (液体流路） 114が連 結されている。また、環状流路 110において、切削液排出流路 114の下流側には、 切屑 1Bを回収するための、磁性体排出流路 116および磁性体回収 BOX118が設 けられている。本実施の形態においては、磁性体排出流路 116および磁性体回収 B OX118により、磁性体回収領域を構成する。  [0032] In a region including the lowermost end of the annular flow path 110, a cutting fluid discharge flow path (C) for guiding a cutting fluid (liquid) 1A in which chips (magnetic substances) 1B are separated from the magnetic substance-containing liquid 1 ( Liquid passage) 114 is connected. In the annular flow path 110, a magnetic substance discharge flow path 116 and a magnetic substance recovery BOX 118 for collecting the chips 1B are provided downstream of the cutting fluid discharge flow path 114. In the present embodiment, the magnetic substance recovery area is constituted by the magnetic substance discharge flow path 116 and the magnetic substance recovery BOX 118.
[0033] (永久磁石 130)  [0033] (Permanent magnet 130)
円筒状ドラム 122の内周面の所定領域には、永久磁石 130が複数配列され、磁気 領域 MAを形成している。本実施の形態において、この磁気領域 MAは、環状流路 1 10の磁性体含有液体導入流路 112の上流側から、切削液排出流路 (液体流路） 11 4を超え、磁性体排出流路 116が設けられる手前までの間の領域となるように、永久 磁石 130が配列されている。この永久磁石 130は、円筒状ドラム 122の回転には追 従せず、配列位置において固定される。 A plurality of permanent magnets 130 are arranged in a predetermined area on the inner peripheral surface of the cylindrical drum 122 to form a magnetic area MA. In the present embodiment, the magnetic region MA is formed in the annular flow passage 110 from the upstream side of the magnetic substance-containing liquid introduction flow passage 112 by the cutting fluid discharge flow passage (liquid flow passage) 11. Permanent magnets 130 are arranged so as to be in a region exceeding 4 and before the magnetic substance discharge channel 116 is provided. The permanent magnet 130 does not follow the rotation of the cylindrical drum 122 and is fixed at the arrangement position.
[0034] 永久磁石 130は、図 2に示すように、それぞれ棒状の形態を有し、円筒状ドラム 12 2の軸方向に沿って配置されている。また、端部の極性が交互に反対となるように配 置されている（N極→S極→N極→S極 · · ·）。永久磁石 130のそれぞれは、図 3に示 すように、小型の棒状磁石 130bを軸方向に沿って複数配置し、各々の棒状磁石 13 Obは、極性が対向するように配置されている。また、棒状磁石 130b同士の間には、 スペイサ一 130cが配置されている。各々の棒状磁石 130bは全体として、被膜 130a により覆われ、全体として 1つの永久磁石 130を構成する。  As shown in FIG. 2, the permanent magnets 130 each have a rod shape, and are arranged along the axial direction of the cylindrical drum 122. The polarities at the ends are alternately opposite (N-pole → S-pole → N-pole → S-pole). As shown in FIG. 3, each of the permanent magnets 130 has a plurality of small bar-shaped magnets 130b arranged in the axial direction, and the bar-shaped magnets 13 Ob are arranged so that their polarities are opposed to each other. Further, a spacer 130c is arranged between the bar-shaped magnets 130b. Each of the bar-shaped magnets 130b is entirely covered with a coating 130a to form one permanent magnet 130 as a whole.
[0035] 永久磁石 130としては、比較的強力な磁力を発生させることが要求されるため棒状 磁石 130bの材質としては、希土類 (Nd、 Fe、 B)磁石を用いることが好ましい。  Since the permanent magnet 130 is required to generate a relatively strong magnetic force, it is preferable to use a rare earth (Nd, Fe, B) magnet as the material of the bar-shaped magnet 130b.
[0036] (水受羽根 124の構造）  (Structure of water receiving blade 124)
次に、水受羽根 124の構造について図 4Aおよび図 4Bを参照して説明する。水受 羽根 124は磁性体含有液体 1を受けて、磁性体含有液体 1の持つ位置エネルギを円 筒状ドラム 122の回転エネルギに変換する役割を有している。したがって、磁性体含 有液体 1の位置エネルギを効率良く回収する観点からは、水受羽根 124に穴を設け ¾V、ほう力 S好まし 、と 、える。  Next, the structure of the water receiving blade 124 will be described with reference to FIGS. 4A and 4B. The water receiving blade 124 has a role of receiving the magnetic substance-containing liquid 1 and converting the potential energy of the magnetic substance-containing liquid 1 into rotational energy of the cylindrical drum 122. Therefore, from the viewpoint of efficiently recovering the potential energy of the magnetic substance-containing liquid 1, a hole is provided in the water receiving blade 124, and ΔV and a force S are preferred.
[0037] 一方、本磁気分離回収装置 100の本質的な目的は、磁力を用いて磁性体含有液 体 1から切屑 1Bを分離する点にある。したがって、環状流路 110を通過する磁性体 含有液体 1は、磁気領域 MAにおいて、なるべく永久磁石 130に近い領域を通過さ せた方が好ましいと考えられる。そこで、本実施の形態における水受羽根 124におい ては、円筒状ドラム 122への付根領域に、磁性体含有液体 1を通過させるための開 口部を設けるようにしている。たとえば、図 4Aに示す水受羽根 124Aにおいては、本 体羽根 125の付根領域に横方向に延びる 1つの開口部 126が設けられる場合を示 し、また、図 4Bに示す水受羽根 124Bにおいては、本体羽根 125の付根領域に複数 の開口部 126が設けられる場合を示している。これらの開口部を設ける形状は、あく までも一例であり、様々な開口部位置、および開口部形状を選択することが可能であ る。 On the other hand, the essential purpose of the present magnetic separation and recovery apparatus 100 is to separate chips 1 B from the magnetic substance-containing liquid 1 by using magnetic force. Therefore, it is considered preferable that the magnetic substance-containing liquid 1 passing through the annular flow channel 110 pass through a region as close to the permanent magnet 130 as possible in the magnetic region MA. Therefore, in the water receiving blade 124 according to the present embodiment, an opening for allowing the magnetic substance-containing liquid 1 to pass therethrough is provided in the root region of the cylindrical drum 122. For example, in the water receiving blade 124A shown in FIG. 4A, a case where one opening 126 extending in the lateral direction is provided in the root region of the main blade 125 is shown, and in the water receiving blade 124B shown in FIG. Also, a case is shown in which a plurality of openings 126 are provided in the root region of the main body blade 125. The shapes in which these openings are provided are merely examples, and various opening positions and opening shapes can be selected. The
[0038] また、この開口部 126を通過させることにより、磁性体含有液体 1から切屑 1Bを効 果的に分離するため、永久磁石 130をこの開口部 126の近傍に集中的に配置させる 構成の採用も可能である。  In order to effectively separate the chips 1 B from the magnetic substance-containing liquid 1 by passing through the opening 126, the permanent magnets 130 are intensively arranged near the opening 126. Recruitment is also possible.
[0039] (動作）  [0039] (Operation)
次に、上記構成からなる磁気分離回収装置 100の動作について、再び図 1を参照 して説明する。工作機械中を循環し、切削屑を含む磁性体含有液体 1は、磁性体含 有液体導入流路 112から、環状流路 110に導入される。環状流路 110に導入された 磁性体含有液体 1は水受羽根 124によって受けられるとともに、磁性体含有液体 1の 自然落下による位置エネルギにより、移動体 120を回転させる。また、磁性体含有液 体 1は、抵抗の少ない開口部 126側を通過することにより、永久磁石 130側に案内さ れ、永久磁石 130からの磁力により、磁性体含有液体 1は、切削液 (液体） 1Aと切屑 1Bとに分離される。  Next, the operation of the magnetic separation and recovery apparatus 100 having the above configuration will be described with reference to FIG. 1 again. The magnetic substance-containing liquid 1 circulating in the machine tool and containing cutting chips is introduced into the annular flow path 110 from the magnetic substance-containing liquid introduction flow path 112. The magnetic substance-containing liquid 1 introduced into the annular flow path 110 is received by the water receiving blade 124, and the movable body 120 is rotated by potential energy due to the natural fall of the magnetic substance-containing liquid 1. Further, the magnetic substance-containing liquid 1 is guided to the permanent magnet 130 side by passing through the opening portion 126 having a small resistance, and the magnetic substance-containing liquid 1 is converted into the cutting liquid ( Liquid) separated into 1A and chips 1B.
[0040] 分離された切削液 (液体） 1Aは、そのまま自然落下により、切削液排出流路 114に 導かれ、再び、工作機械において再利用される。一方、永久磁石 130からの磁力に より吸着された切屑 1 Bは、移動体 120の回転とともに回転方向の下流側に搬送され る。その後、磁気領域 MAを超えた領域において、永久磁石 130からの磁力が切屑 1Bには及ばなくなるため、切屑 1Bは自然落下することになる。切屑 1Bが自然落下 する領域には、磁性体排出流路 116が設けられていることから、この磁性体排出流 路 116を通じて、磁性体回収 BOX118に切屑 1Bが回収されることになる。  [0040] The separated cutting fluid (liquid) 1A is guided to the cutting fluid discharge channel 114 by natural fall as it is, and is reused again in the machine tool. On the other hand, the chips 1 B attracted by the magnetic force from the permanent magnet 130 are conveyed to the downstream side in the rotation direction as the moving body 120 rotates. Thereafter, in a region beyond the magnetic region MA, the magnetic force from the permanent magnet 130 does not reach the chips 1B, and the chips 1B naturally fall. Since the magnetic material discharge channel 116 is provided in the area where the chips 1B naturally fall, the chips 1B are collected in the magnetic material collection BOX 118 through the magnetic material discharge channel 116.
[0041] (作用'効果）  (Action / effect)
以上、本実施の形態における磁気分離回収装置 100によれば、永久磁石 130から の磁力を用いて、切削液 1Aと切屑 1Bとに分離する。また、切屑 1Bは移動体 120とと もに移動する力 磁気領域 MAを通過した後には、永久磁石 130からの磁力が及ば なくなることを積極的に利用して、切屑 1Bを所定位置に回収することを可能としてい る。  As described above, according to magnetic separation and recovery apparatus 100 of the present embodiment, cutting fluid 1A and chips 1B are separated using the magnetic force from permanent magnet 130. Further, after passing the magnetic field MA, the chip 1B moves along with the moving body 120, and actively collects the chip 1B at a predetermined position by actively utilizing the fact that the magnetic force from the permanent magnet 130 does not reach. Is possible.
[0042] また、流路 110を環状流路とし、移動体 120を磁性体含有液体 1が流れる方向に沿 つて回転可能に設け、環状流路 110の最頂部から回転方向にずれた位置に磁性体 含有液体導入流路 112を設けることにより、磁性体含有液体 1の自然落下による位 置エネルギを用いて、移動体 120を回転させることができる。その結果、分離された 切屑 1Bを、磁性体排出流路 116を経由して磁性体回収 BOX118に導く場合にぉ ヽ ても、外部動力を必要とせず、または、補助駆動動力を用いて、装置構成の簡略化、 および小型化を図ることができる。 [0042] Further, the flow path 110 is an annular flow path, and the moving body 120 is provided rotatably along the direction in which the magnetic substance-containing liquid 1 flows, and the magnetic body is located at a position shifted in the rotational direction from the top of the annular flow path 110. body By providing the containing liquid introduction flow channel 112, the moving body 120 can be rotated using the potential energy due to the spontaneous drop of the magnetic substance containing liquid 1. As a result, even when the separated chips 1B are guided to the magnetic material recovery BOX 118 via the magnetic material discharge flow path 116, no external power is required, or the device is operated by using the auxiliary driving power. The configuration can be simplified and the size can be reduced.
[0043] (実施の形態 2) (Embodiment 2)
次に、図 5を参照して、実施の形態 2における磁気分離回収装置について説明する  Next, a magnetic separation and recovery apparatus according to Embodiment 2 will be described with reference to FIG.
[0044] (装置構成） (Device Configuration)
本実施の形態における磁気分離回収装置 200は、側面側から見た場合、略楕円 形状の環状流路 210を有している。この環状流路 210は、斜め上下方向に配置され たプーリ 221に捲きかけられた無端ベルト状部材 222の内周面と、筐体 213の内部 において規定される。無端ベルト状部材 222は、プーリ 221に捲きかけられた状態で 回転可能に設けられている。無端ベルト状部材 222の外周面には、環状流路 210内 において放射状に延びる水受羽根 224が、所定のピッチで複数配置されている。本 実施の形態においては、無端ベルト状部材 222および水受羽根 224により移動体 2 20を構成する。また、無端ベルト状部材 222および水受羽根 224は、榭脂材料その 他の非磁性体物質から構成される。なお、水受羽根 224の詳細構造は、上記実施の 形態 1において述べた水受羽根 124と同様であるため、重複する説明は繰り返さな 、こととする。  The magnetic separation and recovery apparatus 200 according to the present embodiment has a substantially elliptical annular flow path 210 when viewed from the side. The annular flow path 210 is defined on the inner peripheral surface of the endless belt-shaped member 222 wound around the pulley 221 disposed obliquely in the vertical direction and inside the housing 213. The endless belt-shaped member 222 is rotatably provided around the pulley 221. On the outer peripheral surface of the endless belt-shaped member 222, a plurality of water receiving blades 224 extending radially in the annular flow path 210 are arranged at a predetermined pitch. In the present embodiment, the moving body 220 is constituted by the endless belt-shaped member 222 and the water receiving blade 224. The endless belt-shaped member 222 and the water receiving blade 224 are made of a resin material or other non-magnetic substance. Note that the detailed structure of the water receiving blade 224 is the same as that of the water receiving blade 124 described in the first embodiment, and therefore, the description thereof will not be repeated.
[0045] 環状流路 210の最頂部から無端ベルト状部材 222の回転方向（図中の反時計回 転方向）にずれた位置において、上側に位置する無端ベルト状部材 222に対して磁 性体含有液体 1を導入するための磁性体含有液体導入流路 212が、環状流路 210 に設けられている。ここで、磁性体含有液体導入流路 212を環状流路 210の最頂部 力もずれた位置に設けているのは、無端ベルト状部材 222の回転方向を一定方向に するためである。したがって、他の手段により無端ベルト状部材 222の回転方向を一 方向に規制する場合には、磁性体含有液体導入流路 212を環状流路 210の最頂部 を含むように設けることも可能である。 [0046] 環状流路 210の最下端部を含む領域には、磁性体含有液体 1から切屑 IBが分離 された切削液 1Aを導くための切削液排出流路 214が連結されている。また、切削液 排出流路 214の下流側には、切屑 1Bを回収するための、磁性体排出流路 216およ び磁性体回収 BOX218が設けられている。本実施の形態においては、磁性体排出 流路 216および磁性体回収 BOX218により、磁性体回収領域を構成する。 At a position displaced from the top of the annular flow path 210 in the rotation direction of the endless belt-shaped member 222 (counterclockwise rotation in the figure), the magnetic material is positioned relative to the endless belt-shaped member 222 located on the upper side. A magnetic substance-containing liquid introduction channel 212 for introducing the content liquid 1 is provided in the annular channel 210. Here, the reason that the magnetic substance-containing liquid introduction flow path 212 is provided at a position where the top force of the annular flow path 210 is also shifted is to make the rotation direction of the endless belt-shaped member 222 fixed. Therefore, when the rotation direction of the endless belt-shaped member 222 is regulated in one direction by another means, the magnetic substance-containing liquid introduction channel 212 can be provided so as to include the top of the annular channel 210. .

[0047] (永久磁石 230)  [0047] (Permanent magnet 230)
プーリ 221および無端ベルト状部材 222の内周面の所定領域には、永久磁石 230 が複数配列され、磁気領域 MAを形成している。本実施の形態において、この磁気 領域 MAは、環状流路 210の磁性体含有液体導入流路 212の上流側から、切削液 排出流路 (液体流路） 214を超え、磁性体排出流路 216が設けられる手前までの間 の領域となるように、永久磁石 230が配列されている。プーリ 221に配置される永久 磁石 230は、プーリ 221とともに回転し、無端ベルト状部材 222の直線状部分の背面 側には、固定的に配列されている。なお、永久磁石 230の形態および配置条件は、 上記実施の形態 1における永久磁石 130とおなじであるため、重複する説明は繰り 返さないこととする。  A plurality of permanent magnets 230 are arranged in a predetermined area on the inner peripheral surface of the pulley 221 and the endless belt-shaped member 222 to form a magnetic area MA. In the present embodiment, the magnetic region MA extends from the upstream side of the magnetic substance-containing liquid introduction flow path 212 of the annular flow path 210, beyond the cutting fluid discharge flow path (liquid flow path) 214, to the magnetic substance discharge flow path 216. Permanent magnets 230 are arranged so as to be in a region up to the point where is provided. The permanent magnet 230 arranged on the pulley 221 rotates together with the pulley 221 and is fixedly arranged on the back side of the linear portion of the endless belt-shaped member 222. Note that the form and arrangement conditions of permanent magnet 230 are the same as those of permanent magnet 130 in Embodiment 1 described above, and therefore, redundant description will not be repeated.
[0048] (動作）  [0048] (Operation)
次に、上記構成力もなる磁気分離回収装置 200の動作について、図 5を参照して 説明する。工作機械中を循環し、切削屑を含む磁性体含有液体 1は、磁性体含有液 体導入流路 212から、環状流路 210に導入される。環状流路 210に導入された磁性 体含有液体 1は水受羽根 224によって受けられるとともに、磁性体含有液体 1の自然 落下による位置エネルギにより、移動体 220を回転させる。また、磁性体含有液体 1 は、上記実施の形態 1の場合と同様に、抵抗の少ない開口部側を通過することにより 、永久磁石 230側に案内され、永久磁石 230からの磁力により、磁性体含有液体 1 は、切削液 (液体） 1Aと切屑 1Bとに分離される。  Next, the operation of the magnetic separation and recovery apparatus 200 having the above-described configuration will be described with reference to FIG. The magnetic substance-containing liquid 1 circulating in the machine tool and containing cutting chips is introduced into the annular flow path 210 from the magnetic substance-containing liquid introduction path 212. The magnetic substance-containing liquid 1 introduced into the annular flow path 210 is received by the water receiving blades 224, and the movable body 220 is rotated by potential energy due to the natural drop of the magnetic substance-containing liquid 1. Further, the magnetic substance-containing liquid 1 is guided to the permanent magnet 230 side by passing through the opening having a low resistance as in the case of the first embodiment, and is guided by the magnetic force from the permanent magnet 230. Liquid 1 is separated into cutting fluid (liquid) 1A and chips 1B.
[0049] また、本実施の形態の構成によれば、 2つのプーリ 221の間に無端ベルト状部材 2 22を捲きかけて、直線部分を設ける構成を採用していることから、磁性体含有液体 1 を、磁気領域 MAの間に長く存在させることができ、切屑 1Bの分離能力を高めること を可能としている。特に、大きな切屑だけでなぐ微粒子状の切屑であっても、十分に 分離することができる。 Further, according to the configuration of the present embodiment, since the endless belt-shaped member 222 is wound between the two pulleys 221 to provide a linear portion, the magnetic substance-containing liquid is provided. 1 can be present for a long time between the magnetic regions MA, which makes it possible to increase the separation ability of the chip 1B. In particular, even fine-grained chips that can be Can be separated.
[0050] 分離された切削液 (液体） 1Aは、そのまま自然落下により、切削液排出流路 214に 導かれ、再び、工作機械において再利用される。一方、永久磁石 230からの磁力に より、吸着された切屑 1Bは移動体 220の回転とともに、回転方向の下流側（プーリ 22 2側）に搬送される。その後、磁気領域 MAを超えた領域においては、永久磁石 230 力もの磁力が切屑 1Bには及ばなくなるため、切屑 1Bは自然落下することになる。切 屑 1Bが自然落下する領域には、磁性体排出流路 216が設けられていることから、こ の磁性体排出流路 216を通じて、磁性体回収 BOX218に切屑 1Bが回収されること になる。  [0050] The separated cutting fluid (liquid) 1A is guided to the cutting fluid discharge channel 214 by natural fall as it is, and is reused again in the machine tool. On the other hand, the attracted chips 1B are conveyed to the downstream side (the pulley 222 side) in the rotation direction along with the rotation of the moving body 220 by the magnetic force from the permanent magnet 230. Thereafter, in a region beyond the magnetic region MA, the magnetic force of the permanent magnet 230 does not reach the chip 1B, and the chip 1B falls naturally. Since the magnetic substance discharge channel 216 is provided in the area where the chips 1B naturally fall, the chips 1B are collected in the magnetic substance collection BOX 218 through the magnetic substance discharge channel 216.
[0051] (作用'効果）  [0051] (effect)
以上、本実施の形態における磁気分離回収装置 200によっても、上記実施の形態 1における磁気分離回収装置 100と略同様の作用効果を得ることができる。また、 2 つのプーリ 221の間に無端ベルト状部材 222を捲きかけて、直線部分を設ける構成 を採用していることから、磁気領域 MAにおいて、大きな切屑だけでなぐ微粒子状 の切屑であっても、十分に分離することができる。  As described above, the magnetic separation and recovery apparatus 200 according to the present embodiment can also provide substantially the same operation and effect as the magnetic separation and recovery apparatus 100 according to the first embodiment. In addition, since the endless belt-shaped member 222 is wound between the two pulleys 221 to provide a straight portion, even in the magnetic area MA, even fine chips that cannot be replaced only by large chips are used. , Can be sufficiently separated.
[0052] なお、上記実施の形態 1および 2においては、磁性体含有液体 1から切屑 1Bを分 離するための磁力を発生させるものとして、棒形状の永久磁石 130, 230を複数配列 させる構成を採用しているが、棒形状の永久磁石に限らず、シート形状の永久磁石 を用いることも可能である。また、永久磁石に限らず、電磁石を用いることも可能であ る。  In the first and second embodiments, a configuration in which a plurality of bar-shaped permanent magnets 130 and 230 are arranged to generate magnetic force for separating chips 1B from magnetic substance-containing liquid 1 is described. Although it is adopted, it is possible to use not only bar-shaped permanent magnets but also sheet-shaped permanent magnets. In addition, not only permanent magnets but also electromagnets can be used.
[0053] (実施の形態 3)  (Embodiment 3)
次に、図 6から図 8を参照して、実施の形態 3における磁気分離回収装置について 説明する。  Next, a magnetic separation and recovery apparatus according to the third embodiment will be described with reference to FIGS.
[0054] (装置構成） (Device Configuration)
まず、図 6を参照して、本実施の形態における磁気分離回収装置 300は、回転ドラ ム 302と、この回転ドラム 302の回転軸を構成するように、螺旋マグネット部材 305お よびこの螺旋マグネット部材 305を包むように覆うマグネットカバー 306を備えて!/ヽる 。本実施の形態においては、回転ドラム 302の回転軸は、水平方向に配置されてい る力 必要に応じて傾斜させることも可能である。 First, referring to FIG. 6, a magnetic separation and recovery apparatus 300 according to the present embodiment includes a rotating drum 302, a spiral magnet member 305, and a spiral magnet member 305 so as to constitute a rotating shaft of the rotating drum 302. It is equipped with a magnet cover 306 that covers the 305! In the present embodiment, the rotating shaft of rotating drum 302 is disposed in a horizontal direction. It can be tilted as needed.
[0055] ここで、図 9および図 10を参照して、螺旋マグネット部材 305およびマグネットカバ 一 306の構成、およびその機能について説明する。  Here, with reference to FIG. 9 and FIG. 10, the configurations and functions of the spiral magnet member 305 and the magnet cover 306 will be described.
[0056] まず、図 9を参照して、この螺旋マグネット部材 305は、マグネット固定筒 305cの外 周面に、円弧形状の半円マグネット部材 305mを複数個スパイラル型に接合したもの 力もなる。個々の半円マグネット部材 305mは、本実施の形態においては、円弧の内 側に S極、外側に N極を配置させ、突合せ部においては、同極同士で反発させた状 態において、強力接着剤等を用いて接合される。その結果、螺旋マグネット部材 305 の外表面においては、同極の配列となる。なお、本実施の形態では、外表面に N極 を配列させた状態である力 S極を配列させることも可能である。螺旋マグネット部材 305の磁力は、好ましくは、全体にわたって同じ磁力とするのではなぐ一方端側から 他方端側に向力つて徐々に磁力が強くなるように、半円マグネット部材 305mの磁力 が調節される。半円マグネット部材 305mの外表面には、筒状のマグネットカバー 30 6が配設され、螺旋マグネット部材 305 (マグネット固定筒 305c,半円マグネット部材 305m)とマグネットカバー 306とは軸周りに相対的に回転可能な構成となる。  First, referring to FIG. 9, this spiral magnet member 305 is formed by joining a plurality of arc-shaped semi-circular magnet members 305m to the outer peripheral surface of a magnet fixing cylinder 305c in a spiral shape. In the present embodiment, the individual semicircular magnet members 305m are provided with S poles inside the arc and N poles outside the arc, and at the abutting portion, are strongly bonded in a state where the same poles repel each other. It is joined using an agent or the like. As a result, the outer surface of the spiral magnet member 305 has the same polarity arrangement. In the present embodiment, it is also possible to arrange force S poles in a state where N poles are arranged on the outer surface. The magnetic force of the spiral magnet member 305 is preferably adjusted such that the magnetic force gradually increases from one end to the other end, instead of being the same throughout. You. A cylindrical magnet cover 306 is provided on the outer surface of the semicircular magnet member 305m. It becomes a configuration that can be rotated.
[0057] 次に、図 10を参照して、螺旋マグネット部材 305 (マグネット固定筒 305c,半円マ グネット部材 305m)とマグネットカバー 306とを軸周りに相対的に回転させた場合の 、マグネットカバー 306の表面に磁着される切屑 1Bの搬送状態について説明する。 磁性体含有液体 1内に含まれる切屑 1Bは、螺旋マグネット部材 305による磁力に応 じて、螺旋形状にマグネットカバー 306の外表面に付着する。また、一方端側から他 方端側に向力つて徐々に磁力が強くなるように、半円マグネット部材 305mの磁力が 調節されていることから、マグネットカバー 306の一方端側（図 10中右側）の方から、 他方端側に向力 にしたがって徐々に、切屑 1Bの付着量が少なくなつている。  Next, referring to FIG. 10, the magnet cover when the spiral magnet member 305 (magnet fixing cylinder 305c, semicircular magnet member 305m) and the magnet cover 306 are relatively rotated around the axis is described. The transport state of the chips 1B magnetically attached to the surface of the 306 will be described. The chips 1B contained in the magnetic substance-containing liquid 1 adhere to the outer surface of the magnet cover 306 in a spiral shape according to the magnetic force of the spiral magnet member 305. Also, since the magnetic force of the semicircular magnet member 305m is adjusted so that the magnetic force gradually increases from one end to the other end, one end of the magnet cover 306 (right side in FIG. 10) ), The amount of chips 1B deposited gradually decreases toward the other end.
[0058] この状態で、螺旋マグネット部材 305とマグネットカバー 306とを軸周りに相対的に 回転させた場合（半円マグネット部材 305mを右ねじ方向に沿って配列させ、螺旋マ グネット部材 305を右方向側力も見た場合に、螺旋マグネット部材 305を時計回転方 向に回転、マグネットカバー 306が反時計回転方向に回転）、マグネットカバー 306 の表面に付着した切屑 1Bは、磁力の強い側から弱い側に向けて徐々に搬送される ことになる（図中矢印 A方向）。最終的には、螺旋マグネット部材 305の磁力が及ばな くなる領域において、切屑 1Bがマグネットカバー 306の表面から自然落下して、螺旋 マグネット部材 305の一方端側に、切屑 1Bが集められることになる。 In this state, when the spiral magnet member 305 and the magnet cover 306 are relatively rotated around the axis (the semicircular magnet member 305m is arranged along the right-hand thread direction, and the spiral magnet member 305 is When the direction side force is also observed, the spiral magnet member 305 is rotated clockwise, and the magnet cover 306 is rotated counterclockwise.) The chips 1B attached to the surface of the magnet cover 306 are weaker from the side with the stronger magnetic force. Is gradually conveyed toward (The direction of arrow A in the figure). Eventually, in the region where the magnetic force of the spiral magnet member 305 cannot reach, the chips 1B naturally fall from the surface of the magnet cover 306, and the chips 1B are collected on one end side of the spiral magnet member 305. Become.

The rotating drum 302 in the present embodiment has a side plate 302a and a body plate 302b forming an outer surface. The body plate 302b serves to prevent the passage of the magnetic substance-containing liquid 1 into the inside of the rotating drum 302. A plurality of opening holes 302c having a predetermined opening area force for preventing the large chips 1C from invading are provided. Further, a plurality of water receiving blades 304 are provided on the inner surface of the body plate 302b so as to extend radially from the rotation axis. Outside the lower area of the rotating drum 302, a scraper 310 is provided for removing large chips 1C attached to the surface of the body plate 302b, and an area for collecting the large chips 1C is also provided. I have.
[0060] 図 7に示すように、回転ドラム 302の中心部分には、螺旋マグネット部材 305および マグネットカバー 306を取囲むように内筒 307が設けられ、この内筒 307の所定領域 には、軸方向に沿って延び、胴板 302bを通過してきた磁性体含有液体 1を螺旋マグ ネット部材 305およびマグネットカバー 306側に通過させるための切削液出口 308力 S 設けられている。  As shown in FIG. 7, an inner cylinder 307 is provided at the center of the rotating drum 302 so as to surround the spiral magnet member 305 and the magnet cover 306, and a predetermined region of the inner cylinder 307 has a shaft. A cutting fluid outlet 308 is provided to allow the magnetic substance-containing liquid 1 extending along the direction and passing through the body plate 302b to pass to the spiral magnet member 305 and the magnet cover 306 side.
[0061] 螺旋マグネット部材 305は、軸方向には回転せず固定状態に取付けられ、マグネッ トカバー 306がー方端側の側板 302aに固定されることにより、回転ドラム 302の回転 にともなって、マグネットカバー 306が回転する構成が採用されている。切屑 1Bの搬 送側である側板 302aには、切屑 1Bを通過させるために、マグネットカバー 306と側 板 302aとの間には、図 8に示すように、所定間隔の隙間 303が設けられている。  [0061] The spiral magnet member 305 is fixed in a fixed state without rotating in the axial direction, and the magnet cover 306 is fixed to the side plate 302a on the negative end side. A configuration in which the cover 306 rotates is employed. As shown in FIG. 8, a gap 303 at a predetermined interval is provided between the magnet cover 306 and the side plate 302a on the side plate 302a on the side of transporting the chip 1B, in order to allow the chip 1B to pass therethrough.

Tied. Further, a magnetic material recovery BOX 118 is provided in a tip side region of the spiral magnet member 305.
[0063] なお、本実施の形態においては、少なくとも、噴射ノズル 301、回転ドラム 302の内 部、および内筒 307とマグネットカバー 306との隙間力 磁性体含有液体 1を通過さ せるための流路を構成する。 [0063] In the present embodiment, at least the gap force between the injection nozzle 301, the inner portion of the rotary drum 302, and the gap between the inner cylinder 307 and the magnet cover 306 passes through the magnetic substance-containing liquid 1. To form a flow path.
[0064] (動作）  [0064] (Operation)
次に、上記構成からなる磁気分離回収装置 300の磁性体含有液体 1から、切屑を 分離する動作について、図 6を参照しながら説明する。まず、噴射ノズル 301内に磁 性体含有液体 1を供給する。これにより、回転ドラム 302の軸方向長さに沿って、回 転ドラム 302に磁性体含有液体 1が送り込まれる。磁性体含有液体 1に含まれる大型 切屑 1Cは、胴板 302bにより選別され、所定の大きさ以下の切屑を含む磁性体含有 液体 1のみが、回転ドラム 302内に送り込まれる。  Next, an operation of separating chips from the magnetic substance-containing liquid 1 of the magnetic separation and recovery apparatus 300 having the above configuration will be described with reference to FIG. First, the magnetic substance-containing liquid 1 is supplied into the injection nozzle 301. Thus, the magnetic substance-containing liquid 1 is fed into the rotating drum 302 along the axial length of the rotating drum 302. Large chips 1C contained in the magnetic substance-containing liquid 1 are sorted out by the body plate 302b, and only the magnetic substance-containing liquid 1 containing chips having a predetermined size or less is fed into the rotating drum 302.
[0065] 回転ドラム 302内に送り込まれた磁性体含有液体 1は、水受羽根 304に当接 '落下 して、回転ドラム 302を回転させる。回転ドラム 302が回転することにとり、回転ドラム 3 02の外周面に捕獲された大型切屑 1Cは、スクレーバ 310により剥ぎ取られ、所定の 回収領域に集められる。一方、回転ドラム 302内に送り込まれた磁性体含有液体 1は 、回転ドラム 302の回転にともない、マグネットカバー 306の表面に、切屑 1Bが螺旋 状に磁着されるとともに、回収側に序所に搬送される。切屑 1Bが分離された切削液 1 Aは、内筒 307とマグネットカバー 306との隙間力 切削液出口 308に達して、切削 液排出流路 114に送り出される。  [0065] The magnetic substance-containing liquid 1 sent into the rotating drum 302 abuts on the water receiving blade 304 and falls, causing the rotating drum 302 to rotate. With the rotation of the rotating drum 302, the large chips 1C captured on the outer peripheral surface of the rotating drum 302 are peeled off by the scraper 310 and collected in a predetermined collecting area. On the other hand, with the rotation of the rotating drum 302, the magnetic substance-containing liquid 1 sent into the rotating drum 302 causes the chips 1B to be spirally magnetized on the surface of the magnet cover 306, and to the recovery side at the beginning. Conveyed. The cutting fluid 1A from which the chips 1B are separated reaches the gap force between the inner cylinder 307 and the magnet cover 306, reaches the cutting fluid outlet 308, and is sent out to the cutting fluid discharge channel 114.
[0066] マグネットカバー 306の表面に磁着した切屑 1Bは、マグネットカバー 306と側板 30 2aとの隙間 303を通過し、螺旋マグネット部材 305の磁力が及ばなくなる先端部領 域において、切屑 1Bがマグネットカバー 306の表面から自然落下して、磁性体回収 BOXに集められることになる。  The chips 1B magnetically attached to the surface of the magnet cover 306 pass through the gap 303 between the magnet cover 306 and the side plate 302a, and the chips 1B become magnetized in the tip region where the magnetic force of the spiral magnet member 305 does not reach. It falls naturally from the surface of the cover 306 and is collected in the magnetic material recovery box.
[0067] (作用'効果）  (Effect)
以上、本実施の形態における磁気分離回収装置 300によっても、上記実施の形態 1における磁気分離回収装置 100と略同様の作用効果を得ることができる。また、本 実施の形態においては、マグネットカバー 306の表面に螺旋磁気部材 305からの磁 力により磁着した磁性体 1Bは、螺旋状に配置される螺旋磁気部材 305に対するマグ ネットカバー 306の軸周り回転により、螺旋状に所定の軸方向に搬送されることにな る。その結果、送り方向の先端部においては、最終的には、螺旋マグネット部材 305 からの磁力が及ばなくなり、マグネットカバー 306の表面力も磁性体 1Bが剥がれ、分 離手段の軸方向先端側に、磁性体含有液体 1から分離された磁性体 1Bを回収する ことが可能となる。その結果、上下方向での磁性体含有液体 1の落下距離を小さくす ることが可能となるため、磁気分離回収装置 300の高さ方向の小型化を図ることが可 會 になる。 As described above, the magnetic separation and recovery apparatus 300 according to the present embodiment can also provide substantially the same operation and effect as the magnetic separation and recovery apparatus 100 according to the first embodiment. Further, in the present embodiment, the magnetic body 1B magnetically attached to the surface of the magnet cover 306 by the magnetic force from the spiral magnetic member 305 is disposed around the axis of the magnet cover 306 with respect to the spiral magnetic member 305 arranged in a spiral shape. Due to the rotation, the sheet is conveyed spirally in a predetermined axial direction. As a result, at the leading end in the feed direction, the magnetic force from the helical magnet member 305 finally stops, and the surface force of the magnet cover 306 also peels off the magnetic body 1B. The magnetic substance 1B separated from the magnetic substance-containing liquid 1 can be collected at the tip end in the axial direction of the separating means. As a result, the falling distance of the magnetic substance-containing liquid 1 in the vertical direction can be reduced, so that the magnetic separation and recovery apparatus 300 can be downsized in the height direction.
[0068] (実施の形態 4)  (Embodiment 4)
次に、図 11および図 12を参照して、実施の形態 4における磁気分離回収装置につ いて説明する。  Next, a magnetic separation and recovery apparatus according to Embodiment 4 will be described with reference to FIG. 11 and FIG.

次に、図 44および図 45を参照して、螺旋マグネット部材 2200の詳細構造につい て説明する。両図を参照して、この螺旋マグネット部材 2200は、回転軸 2201と、こ の回転軸 2201に固定されるマグネット固定筒 2202とを有している。このマグネット固 定筒 2202には鋼管が用いられ、外径 (L2)は約 70mm程度である。マグネット固定 筒 2202の外表面には、ブロック型の永久磁石 2203が、全体として螺旋形状となるよ うに所定のピッチで配置されて 、る。  Next, the detailed structure of the spiral magnet member 2200 will be described with reference to FIGS. 44 and 45. Referring to both figures, the spiral magnet member 2200 has a rotating shaft 2201 and a magnet fixing cylinder 2202 fixed to the rotating shaft 2201. A steel pipe is used for the magnet fixing cylinder 2202, and the outer diameter (L2) is about 70 mm. On the outer surface of the magnet fixing cylinder 2202, block-shaped permanent magnets 2203 are arranged at a predetermined pitch so as to form a spiral shape as a whole.
[0114] 永久磁石 2203の形状は、図 45Aの正面図および図 45Bの左側面図に示すように 、断面が扇型の形状を有し、底面 2203aは平面であり、表面 2203bは上方に吐出す る湾曲形状を有し、長さ ）は約 50mm、高さは約 15mm、幅は約 30mmである。ま た、表面 2203bの曲率半径は、約 48. 5mmである。永久磁石 2203の材質としては 、比較的強力な磁力を発生させることが要求されるため、希土類 (Nd、 Fe、 B)磁石を 用いることが好ましい。本実施の形態においては、ネオジム製の永久磁石を用いて いる。永久磁石 2203の配置は、図 44に示すように、永久磁石 2203の長さ（P)の半 分のピッチである 25mm (PZ2)のピッチで、永久磁石 2203の表面の磁性が交互に 反対となるように配置されている（N極→S極→N極→S極 · ' 。 [0114] As shown in the front view of Fig. 45A and the left side view of Fig. 45B, the shape of the permanent magnet 2203 has a fan-shaped cross section, the bottom surface 2203a is flat, and the surface 2203b is discharged upward. It has a curved shape with a length of about 50 mm, a height of about 15 mm and a width of about 30 mm. The radius of curvature of the surface 2203b is about 48.5 mm. As a material of the permanent magnet 2203, it is required to generate a relatively strong magnetic force, and therefore, it is preferable to use a rare earth (Nd, Fe, B) magnet. In the present embodiment, a permanent magnet made of neodymium is used. As shown in Fig. 44, the permanent magnet 2203 is arranged at a pitch of 25mm (PZ2), which is half the pitch (P) of the length of the permanent magnet 2203, and the magnetism on the surface of the permanent magnet 2203 alternates. They are arranged to be opposite (N pole → S pole → N pole → S pole · '.
[0115] さらに、螺旋状に配置された永久磁石 2203の外表面には、永久磁石 2203が取り 付けられたマグネット固定筒 2202に対して、軸周りに相対的に回転可能な筒状のマ グネットカバー 2204が設けられている。本実施の形態においては、マグネットカバー 2204には、ステンレス製のパイプが用いられ、外径は約 105mmであり、マグネット力 バー 2204の内周面と永久磁石 2203の表面とのクリアランスは約 lmm— 2mm程度 である。本実施の形態においては、マグネット固定筒 2202を回転軸 2201に連結さ せていることから、マグネットカバー 2204は、フレーム 2101に固定的に設けられてい る。なお、マグネットカバー 2204を回転軸 2201に連結させ、マグネット固定筒 2202 をフレーム 2101に固定的に設ける構成の採用も可能である。 [0115] Further, the outer surface of the spirally arranged permanent magnet 2203 has a cylindrical magnet rotatable around an axis relative to the magnet fixed cylinder 2202 to which the permanent magnet 2203 is attached. A cover 2204 is provided. In the present embodiment, a stainless steel pipe is used for the magnet cover 2204, the outer diameter is about 105 mm, and the clearance between the inner peripheral surface of the magnet force bar 2204 and the surface of the permanent magnet 2203 is about lmm— It is about 2mm. In the present embodiment, since magnet fixing cylinder 2202 is connected to rotating shaft 2201, magnet cover 2204 is fixedly provided on frame 2101. Note that a configuration in which the magnet cover 2204 is connected to the rotating shaft 2201 and the magnet fixing cylinder 2202 is fixedly provided on the frame 2101 is also possible.
[0116] 上記構成力もなる螺旋マグネット部材 2200において、図 46に示すように、マグネッ トカバー 2204と筒状管 2210との間において切屑含有切削油 2001を流すための流 路が形成され、切屑含有切削油 2001に含まれる切屑 2001B力 永久磁石 2203の 磁力に基づき、マグネットカバー 2204の表面に着磁することになる。さらに、永久磁 石 2203は螺旋状に配置されて軸周りに回転していることから (本実施の形態の場合 、図 46の右側から見て、マグネット固定筒 2202を反時計回転方向に回転）、見かけ 上マグネットカバー 2204の表面に生じる磁界 Mは、図 47に示すように、右側から左 側に向力つて移動することとなり、切屑含有切削油 2001を流す方向と同じ方向に切 屑 2001Bを搬送することが可能となる。 As shown in FIG. 46, in the spiral magnet member 2200 having the above-described constitutional force, a flow path for flowing the chip-containing cutting oil 2001 is formed between the magnet cover 2204 and the cylindrical tube 2210, and the chip-containing cutting The chip 2001B force contained in the oil 2001 is magnetized on the surface of the magnet cover 2204 based on the magnetic force of the permanent magnet 2203. Further, since the permanent magnet 2203 is spirally arranged and rotates around the axis (in the case of the present embodiment, the magnet fixed cylinder 2202 is rotated in the counterclockwise direction as viewed from the right side in FIG. 46). As shown in FIG. 47, the magnetic field M generated on the surface of the magnet cover 2204 apparently moves from the right side to the left side to move the chip 2001B in the same direction as the direction in which the chip-containing cutting oil 2001 flows. It can be transported.
[0117] ここで、切屑 2001Bを吸引するための永久磁石 2203の磁力について説明する。 [0117] Here, the magnetic force of the permanent magnet 2203 for attracting the chips 2001B will be described.
図 48は、永久磁石 2203と切屑 2001Bとの距離の関係を示す図であり、切屑含有切 削油 2001に最も含まれる含有確の高い、大きさが約 0. 5mm— 1. Ommを切屑 200 1Bとして配置した。様々な磁力を有する永久磁石 2203を用いて実験した結果、永 久磁石 2203と切屑 2001Bとの距離 Wに関係なぐ切屑 2001Bに及ぶ磁力が 200 ガウス（2 X 10—2テスラ (T) )以上であれば、切屑 2001Bを永久磁石 2203により磁着 できることがわかった。 Fig. 48 is a diagram showing the relationship between the distance between the permanent magnet 2203 and the chip 2001B. The chip-containing cutting oil 2001 contains the most probable content of 0.5 mm-1. Placed as 1B. In various magnetic force results of experiments using permanent magnet 2203 having a magnetic force of 200 gauss spanning relationship Nag chips 2001B to the distance W between the permanent magnet 2203 and the chip 2001B (2 X 10- 2 tesla (T)) or If there was, it was found that the chips 2001B could be magnetized by the permanent magnet 2203.
[0118] そこで、図 49Aに示すように、本実施の形態における螺旋マグネット部材 2200に おいて、まず、表面磁力が、約 5600ガウス（X 10—4テスラ (T) )の範囲ある各永久磁 石 2203 (磁石 A— Iと標記）において、各永久磁石 2203の表面中心位置から半径 方向に遠ざかった各距離位置（3mm位置（マグネットカバー 2204の外表面位置）か ら、 5mm間隔で 53mmまで)での磁力を測定した。測定結果を表に表わしたものが 図 49Bであり、縦軸にガウス（10— 2テスラ (T) )、横軸に永久磁石 2203の表面からの 距離をとつて、グラフに表わしたもの力 図 49Cである。永久磁石 2203からの磁力が 200ガウス（2 X 10— 2テスラ（T) )以上となるのは、図 49B力 、少なくと 43mm以下で あれば良いことが分力る。 [0118] Therefore, as shown in FIG. 49A, Oite helically magnet member 2200 in the present embodiment, first, the surface magnetic force, the permanent magnetic in the range of about 5600 gauss (X 10- 4 Tesla (T)) On the stone 2203 (marked with magnets A–I), each distance position (from the 3 mm position (the outer surface position of the magnet cover 2204) away from the center of the surface of each permanent magnet 2203 in the radial direction, to 53 mm at 5 mm intervals) The magnetic force at was measured. That the measurement results were expressed in Table is a diagram 49B, Gaussian vertical axis (10-2 tesla (T)), the horizontal axis and the distance from the surface of the permanent magnet 2203 connexion, a force diagram that represents the graph 49C. The magnetic force from the permanent magnet 2203 is 200 gauss (2 X 10- 2 tesla (T)) above, FIG 49B force, be sufficient if 43mm or less and less Bunryokuru.
[0119] 本実施の形態においては、再び図 46を参照して、永久磁石 2203の表面と筒状管 2210の内面との距離 (W)を 43mmに設定している。これにより、永久磁石 2203に 対向する筒状管 2210の内面領域の磁力を 2 X 10— 2テスラ (T)以上にすることができ 、切屑含有切削油 2001に含まれる切屑 2001Bを確実に捕獲することが可能となる。 なお、永久磁石 2203の表面と筒状管 2210の内面との距離 (W)は 43mmに限定さ れず、 43mm以下で、切屑含有切削油 2001の流れに悪影響を与えない範囲で設 定されるちのである。 In the present embodiment, referring to FIG. 46 again, the distance (W) between the surface of permanent magnet 2203 and the inner surface of cylindrical tube 2210 is set to 43 mm. As a result, the magnetic force in the inner surface region of the cylindrical tube 2210 facing the permanent magnet 2203 can be made 2 × 10-2 Tesla (T) or more, and the chips 2001B contained in the chip-containing cutting oil 2001 can be reliably captured. It becomes possible. The distance (W) between the surface of the permanent magnet 2203 and the inner surface of the cylindrical tube 2210 is not limited to 43 mm, but is set to be 43 mm or less and within a range that does not adversely affect the flow of the chip-containing cutting oil 2001. It is.
[0120] なお、他の形態として、マグネット固定筒 2202の外表面に配置した永久磁石 (ネオ ジム磁石） 2203の表面での磁力が 0. 56テスラ（T)、永久磁石 2203の表面とマグネ ットカバー 2204の内表面との間の距離が 7. 5mmの場合であっても、永久磁石 220 3に対向する筒状管 2210の内面領域の磁力を 2 X 10— 2テスラ (T)以上にすることが できることが分力つた。なお、この場合のマグネットカバー 2204の外表面での磁力は 、約 0. 2テスラ (T)である。 [0120] As another form, the magnetic force on the surface of the permanent magnet (neodymium magnet) 2203 disposed on the outer surface of the magnet fixing cylinder 2202 is 0.56 Tesla (T), and the surface of the permanent magnet 2203 and the magnet cover the distance between the inner surface of the 2204 even for 7. 5 mm, that the magnetic force of the inner surface area of the cylindrical tube 2210 that faces the permanent magnet 220 3 to 2 X 10- 2 tesla (T) or higher What I could do was help. In this case, the magnetic force on the outer surface of the magnet cover 2204 is about 0.2 Tesla (T).

次に、回転ドラム 2300内に設けられる水受羽根 2303の詳細形状について、図 50 および図 51を参照して説明する。この水受羽根 2303においては、切削油 2001Aの 有するエネルギを回転エネルギに効率良く変換する観点から、羽根部 2303aの先端 部分に、回転方向に向力つて凹む溝状の凹部領域 2303bが設けられている。また、 回転軸 2302よりも上方に位置する羽根部 2303aの外周部と受槽 2301の内壁との 間は、水密性 (シール性)を確保する処理が施されている。なお、本実施の形態にお ける水受羽根 2303の長さは約 125mm、幅約 300mmである。このように、水受羽根 2303に凹部領域 2303bを設けることで、切削油 2001Aがー且この凹部領域 2303 bに蓄えられるため、凹部領域 2303bに蓄えられた切削油 2001Aの位置エネルギを 、回転軸 2302を回転させるための回転エネルギに効率良く変換することができる。 Next, the detailed shape of the water receiving blade 2303 provided in the rotating drum 2300 will be described with reference to FIG. 50 and FIG. In the water receiving blade 2303, from the viewpoint of efficiently converting the energy of the cutting oil 2001A into rotational energy, a groove-shaped concave region 2303b is provided at the tip portion of the blade portion 2303a so as to be concave in the rotational direction. I have. Further, between the outer peripheral portion of the blade portion 2303a located above the rotary shaft 2302 and the inner wall of the receiving tank 2301, a process for ensuring watertightness (sealing property) is performed. The length of the water receiving blade 2303 in this embodiment is about 125 mm and the width is about 300 mm. Thus, the water receiving blade By providing the recessed area 2303b in 2303, the cutting oil 2001A is stored in the recessed area 2303b, and the potential energy of the cutting oil 2001A stored in the recessed area 2303b is used to rotate the rotary shaft 2302. It can be efficiently converted to energy.

次に、図 52を参照して、実施の形態 15における磁気分離回収装置 2100Aの構造 について説明する。この実施の形態 15における磁気分離回収装置 2100Aの構造 的特長は、筒状管の形状、および、切屑 2001Bの搬出方向に対する切屑含有切削 油 2001の流れ方向にある。まず、本実施の形態における切屑含有切削油 2001の 流れ方向は、実施の形態 14とは異なり、切屑 2001Bの搬出方向とは反対方向に流 れるように設けられている。したがって、切削油導入管 2211は、筒状管 2210のガイ ドボックス 2110側に設けられ、また、切削油 2001Aを排出するための切削油出口 2 210dは、プーリ 2103側に設けられ、切削油出口 2210dと切削油導入管 2301aとを 連結するための流路が形成されることになる。  Next, the structure of a magnetic separation and recovery apparatus 2100A according to Embodiment 15 will be described with reference to FIG. The structural features of the magnetic separation and recovery apparatus 2100A in the fifteenth embodiment are in the shape of the cylindrical tube and the flow direction of the chip-containing cutting oil 2001 with respect to the direction in which the chips 2001B are carried out. First, unlike Embodiment 14, the flow direction of the chip-containing cutting oil 2001 in the present embodiment is provided so as to flow in the direction opposite to the direction in which the chip 2001B is carried out. Accordingly, the cutting oil introduction pipe 2211 is provided on the guide box 2110 side of the tubular pipe 2210, and the cutting oil outlet 2 210d for discharging the cutting oil 2001A is provided on the pulley 2103 side, and the cutting oil outlet is provided. A flow path for connecting 2210d and the cutting oil introduction pipe 2301a is formed.
[0124] 次に、筒状管の形状について説明する。本実施の形態における筒状管 2210Aは 、切屑含有切削油 2001の流れの最も下流側（最もプーリ 2103側）に、永久磁石 22 03の表面からの距離 (W1)が 43mmに設定される第 1内径領域 2210aと、この第 1 内径領域 2210aよりも上流側にぉ 、て、第 1内径領域 2210aよりも内径が大き!/、第 2 内径領域 2210b (W2>Wl)と、さらに、この第 2内径領域 2210bよりも上流側にお V、て、第 2内径領域 2210bよりも内径が大き 、第 3内径領域 2210c (W3 >W2)とを 備えている。 [0124] Next, the shape of the cylindrical tube will be described. The cylindrical pipe 2210A in the present embodiment is the first pipe in which the distance (W1) from the surface of the permanent magnet 2203 is set to 43 mm at the most downstream side (most pulley 2103 side) of the flow of the chip-containing cutting oil 2001. The inner diameter region 2210a and the upstream side of the first inner diameter region 2210a have a larger inner diameter than the first inner diameter region 2210a! Inner diameter region 2210b (W2> Wl), and furthermore, V on the upstream side of the second inner diameter region 2210b, the inner diameter is larger than the second inner diameter region 2210b, and the third inner diameter region 2210c (W3> W2) Is provided.
[0125] このように、第 3内径領域 2210c側から切屑含有切削油 1を流すことにより、第 1内 径領域 2210aを通過しないような大きな径の切屑 2001Bが流れてきた場合には、切 屑含有切削油 2001の流れの早い段階である上流側で切屑 2001Bを永久磁石 220 3の磁力により着磁させることが可能となる。ここで、切屑 2001Bの大きさが大きい程 、切屑 2001Bに及ぶ磁力の吸引力は大きくなることが知られている。よって、永久磁 石 2203の表面から 43mm以上の距離であっても、外径が 1. Omm以上であれば、こ の領域または、次の第 2内径領域 2210bにおいて、切屑 2001Bを着磁させることが できる。その後、外径が 1. Omm以下の切屑 2001Bの切屑 2001Bは、第 3内径領域 2210cにおいて切屑 2001Bを着磁させることができる。このようにして、実施の形態 14の場合、全ての領域力 3mmに設けられることで、大きな切屑の固まりが流れてき た場合、流路の一部を塞ぎ、これにより切屑含有切削油 2001の流れ抵抗が大きくな ることが考えられたが、本実施の形態においては、段階的に流路の内径を小さくし、 最も小さい内径部分を、実施の形態 14の場合と同様にし、切屑含有切削油 2001の 流れ方向を、切屑 2001Bの搬送方向とは逆方向にすることで、切屑 2001Bによる流 路の一部閉塞を未然に防止することを可能としている。  [0125] As described above, when the chip-containing cutting oil 1 flows from the third inner diameter region 2210c side, when the chips 2001B having a large diameter that does not pass through the first inner diameter region 2210a flow, the chips are removed. The chips 2001B can be magnetized by the magnetic force of the permanent magnet 2203 on the upstream side, which is an early stage of the flow of the cutting oil 2001. Here, it is known that the larger the size of the chip 2001B, the greater the magnetic attraction force exerted on the chip 2001B. Therefore, even if the outer diameter is 1.Omm or more, even if the distance is 43 mm or more from the surface of the permanent magnet 2203, the chips 2001B should be magnetized in this area or the next second inner diameter area 2210b. Can be done. Thereafter, the chips 2001B having the outer diameter of 1. Omm or less can be magnetized in the third inner diameter region 2210c. In this way, in the case of the fourteenth embodiment, by setting the entire area force to 3 mm, when a large lump of chips is flowing, a part of the flow path is blocked, thereby the flow of the chip-containing cutting oil 2001. Although it was considered that the resistance increased, in the present embodiment, the inner diameter of the flow path was gradually reduced, and the smallest inner diameter portion was made the same as in the case of Embodiment 14, and the chip-containing cutting oil was used. By setting the flow direction of 2001 to be opposite to the direction in which the chips 2001B are transported, it is possible to prevent partial blockage of the flow path by the chips 2001B.
[0126] (実施の形態 16)  (Embodiment 16)
次に、図 53および図 54を参照して、実施の形態 16における磁気分離回収装置 21 00Bの構造について説明する。この実施の形態 16における磁気分離回収装置 210 0Bの構造的特長は、磁気分離回収装置 2200に用いられるマグネットカバーの形状 に特徴を有している。本実施の形態におけるマグネットカバー 2204Aにおいては、 永久磁石 2203の螺旋配置に沿って、螺旋状のガイド立壁 2220が設けられて 、る。 このようにマグネットカバー 2204Aの表面にガイド立壁 2220を設けることにより、ガイ ド立壁 2220の沿って切屑 2001Bを搬送させることが可能となり、切屑 2001Bの搬出 効率を向上させることが可能となる。  Next, the structure of the magnetic separation and recovery apparatus 2100B in the sixteenth embodiment will be described with reference to FIG. 53 and FIG. The structural feature of the magnetic separation and recovery device 2100B in the sixteenth embodiment is characterized by the shape of the magnet cover used in the magnetic separation and recovery device 2200. In the magnet cover 2204A according to the present embodiment, a spiral guide standing wall 2220 is provided along the spiral arrangement of the permanent magnet 2203. By providing the guide standing wall 2220 on the surface of the magnet cover 2204A in this manner, the chips 2001B can be transported along the guide standing walls 2220, and the efficiency of carrying out the chips 2001B can be improved.
[0127] なお、上記各実施の形態において、マグネットカバー 2204の外表面での磁力は約 0. 2Tとなるように設定している力 永久磁石 2203の表面とマグネットカバー 2204の 内表面との距離が小さいと、マグネットカバー 2204の外表面での磁力は大きくなり、 マグネットカバー 2204の外表面での磁性体の搬送速度は遅くなる。一方、永久磁石 2203の表面とマグネットカバー 2204の内表面との距離を大きくすると、マグネット力 バー 2204の外表面での磁力は小さくなり、マグネットカバー 2204の外表面での磁 性体の搬送速度は早くなる。したがって、磁気分離回収装置の規模、回収能力に応 じて、永久磁石 2203の表面とマグネットカバー 2204の内表面との距離が設定される [0127] In each of the above embodiments, the magnetic force on the outer surface of the magnet cover 2204 is approximately Force set to be 2T When the distance between the surface of the permanent magnet 2203 and the inner surface of the magnet cover 2204 is small, the magnetic force on the outer surface of the magnet cover 2204 increases, and the outer surface of the magnet cover 2204 The transport speed of the magnetic material at the time becomes slow. On the other hand, when the distance between the surface of the permanent magnet 2203 and the inner surface of the magnet cover 2204 is increased, the magnetic force on the outer surface of the magnet force bar 2204 decreases, and the speed of transport of the magnetic material on the outer surface of the magnet cover 2204 decreases. Be faster. Therefore, the distance between the surface of the permanent magnet 2203 and the inner surface of the magnet cover 2204 is set according to the size and recovery capacity of the magnetic separation and recovery device.
[0128] また、上記各実施の形態において、永久磁石 2203に対向する筒状管 2210の内 面領域の磁力を 2 X 10— 2テスラ (Τ)以上であるように磁力の最適化を図って!/、るが、 この磁力の最適化に関しては、本実施の形態の装置に示す構成に限定されず、螺 旋マグネット部材 2200の回転軸 2201の回転に、駆動モータ等を用いる構成であつ ても構わない。 In each of the above embodiments, the magnetic force was optimized such that the magnetic force in the inner surface area of the cylindrical tube 2210 facing the permanent magnet 2203 was 2 × 10 −2 Tesla (Τ) or more. ! / However, the optimization of the magnetic force is not limited to the configuration shown in the apparatus of the present embodiment, but is a configuration in which a drive motor or the like is used to rotate the rotation shaft 2201 of the spiral magnet member 2200. No problem.
[0129] また、上記実施の形態の特徴を部分的に適宜組み合わせて用いることも可能であ る。したがって、今回開示した上記実施の形態はすべての点で例示であって、限定 的な解釈の根拠となるものではない。したがって、本発明の技術的範囲は、上記した 実施の形態のみによって解釈されるのではなぐ請求の範囲の記載に基づいて画定 される。また、請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。  [0129] Further, the features of the above-described embodiment can be partially combined as appropriate.
