Description

本発明は切削盤で削られた切粉や研削盤で削られた鉄粉をタンクから排出する切粉・鉄粉の搬送装置及び分離搬送システムに関する。   The present invention relates to a chip / iron powder transfer device and a separation transfer system for discharging chips cut by a cutting machine or iron powder cut by a grinding machine from a tank.

切削盤又は研削盤等の成形機械で削られた切粉・鉄粉等は、循環する冷却水によってタンクに回収される。タンク内の冷却水は循環されることから、通常、切粉や鉄粉を含まないように、切粉・鉄粉を分離して排出するようにしている。従来においては、図１０〜１１に示すように、切粉・鉄粉分離除去装置５０は、回転可能な吸着ドラム型のオイルセパレータ５５と呼ばれるものを使用して行われていた。このオイルセパレータ５５は、特許文献１によっても示されているように、吸着ドラム５６の周壁内に沿って、多数の鉄板５７を設置し、吸着ドラム５５の周壁内面位置側に対向して永久磁石５８を鉄板の回転移動時に追従できるように設置している。また、吸着ドラム５６の内面の他側には鉄板５７の消磁装置として電磁石５９を設置して構成されている。   Chips, iron powder, and the like shaved by a molding machine such as a cutting machine or a grinding machine are collected in a tank by circulating cooling water. Since the cooling water in the tank is circulated, the chips and iron powder are usually separated and discharged so as not to contain chips and iron powder. Conventionally, as shown in FIGS. 10 to 11, the chip / iron powder separation / removal device 50 is performed using a so-called rotatable adsorption drum type oil separator 55. As shown in Patent Document 1, the oil separator 55 is provided with a large number of iron plates 57 along the peripheral wall of the suction drum 56, and is opposed to the inner surface position side of the peripheral surface of the suction drum 55. 58 is installed so that it can follow when the iron plate rotates. Further, an electromagnet 59 is installed on the other side of the suction drum 56 as a demagnetizing device for the iron plate 57.

図１１に示すように、このオイルセパレータ５５を使用する切粉・鉄粉分離除去装置５０は、タンク５１内を切粉・鉄粉回収部５２と冷却水送給部５３とに２分割するとともに、オイルセパレータ５５を切粉・鉄粉回収部５２側に配置していた。切削盤又は研削盤等の成形機械５４から、循環する冷却水とともにタンク５１内に回収された切粉・鉄粉は、オイルセパレータ５５によって永久磁石５８で吸着ドラム５６に吸着され、シュートの部位において手で剥ぎ取られることによって排出されていた。   As shown in FIG. 11, the chip / iron powder separation / removal device 50 using the oil separator 55 divides the tank 51 into a chip / iron powder recovery unit 52 and a cooling water supply unit 53. The oil separator 55 is disposed on the chip / iron powder collecting unit 52 side. The chips and iron powder collected in the tank 51 together with the circulating cooling water from the molding machine 54 such as a cutting machine or a grinding machine are adsorbed to the adsorption drum 56 by the permanent magnet 58 by the oil separator 55, and at the chute site. It was discharged by being peeled off by hand.

これによって、切粉・鉄粉が除去された冷却水は冷却水送給部５３に流入され、冷却水がタンク５１から成形機械５４内に循環できることとなっていた。
特開平５−５７２１１号公報（２〜３頁、図１参照） As a result, the cooling water from which the chips and iron powder have been removed flows into the cooling water feeding unit 53, and the cooling water can be circulated from the tank 51 into the molding machine 54.
Japanese Patent Laid-Open No. 5-57211 (see pages 2-3 and FIG. 1)

しかし、特許文献１に記載されているオイルセパレータ５５は、希土類の磁石を使用しているため磁力が大きく、また複雑に構成されていることからコストが高くなっていた。しかもこのオイルセパレータ５５を使用する切粉・鉄粉分離除去装置５０は、タンク５１を２分割に構成するとともに切粉・鉄粉を切削盤５４からタンクに戻すためのポンプ６０と、タンク５１内の切粉・鉄粉をオイルセパレータ５５に吸引するポンプ６１とを備えることになるから、部品点数を多くしてコストを上昇させることとなっていた。しかも、吸着ドラム５６内に可動部を有していることからメンテナンスの必要が生じて手間のかかることとなっていた。   However, since the oil separator 55 described in Patent Document 1 uses a rare earth magnet, the oil separator 55 has a high magnetic force and has a complicated structure, which increases the cost. Moreover, the chip / iron powder separation / removal device 50 using the oil separator 55 is configured to divide the tank 51 into two parts and return the chip / iron powder from the cutting board 54 to the tank, The pump 61 for sucking the chips and iron powder into the oil separator 55 is provided, which increases the number of parts and increases the cost. Moreover, since the movable part is provided in the suction drum 56, it is necessary to perform maintenance, which is troublesome.

本発明は、上述の課題を解決するものであり、簡単な構成でしかも廉価に構成するとともにメンテナンスフリーで行なうことのできる切粉・鉄粉の搬送装置及び分離搬送システムを提供することを目的とする。そのため、本発明に係る切粉・鉄粉の搬送装置は、

この発明によれば、切粉・鉄粉搬送装置は、鉄芯に巻回されたコイルに位相の異なる交流電流、例えば、二相又は三相交流の電流を流すことによって合成磁界を発生させる。合成磁界は時間とともに移動する移動磁界を形成することから、搬送面の一端に移動した切粉・鉄粉は吸引されて搬送面上を磁力で移動することとなり、搬送装置の他端から外部に排出される。従って、搬送装置の一端を、例えば、冷却水とともに循環された切粉・鉄粉が流入されているタンク内に配置し、他端をタンク外に配置すれば、タンク内の切粉・鉄粉は外部に排出されて冷却水を機内に送給することができる。このように、切粉・鉄粉搬送装置は、鉄芯とコイル及び搬送面だけの構成で切粉や鉄粉を搬送できることから高価なオイルセパレータを使用することなく簡単で廉価に構成することができる。しかも、この搬送装置はオイルセパレータのメンテナンスを必要としないことから手間がかかることもない。   According to the present invention, the chip / iron powder conveying device generates a combined magnetic field by flowing alternating currents having different phases, for example, two-phase or three-phase alternating currents, through a coil wound around an iron core. Since the combined magnetic field forms a moving magnetic field that moves with time, the chips and iron powder that have moved to one end of the transfer surface are attracted and moved on the transfer surface by magnetic force. From the other end of the transfer device to the outside Discharged. Therefore, if one end of the transfer device is placed in, for example, a tank into which chips / iron powder circulated with cooling water is introduced and the other end is placed outside the tank, the chips / iron powder in the tank Can be discharged to the outside and feed cooling water into the machine. In this way, the chip / iron powder conveying device can be configured simply and inexpensively without using an expensive oil separator because it can convey chips and iron powder with a configuration of only an iron core, a coil and a conveying surface. it can. Moreover, since this transport device does not require maintenance of the oil separator, it does not take time.

なお、搬送面が、非磁性材であれば切粉・鉄粉の搬送を良好にするものであるが、それに限らず、透磁率が１．０１〜５５００の弱磁性材、あるいは３．５ｍｍ以内の厚みの薄い鉄板であってもよい。   In addition, if a conveyance surface is a nonmagnetic material, it will improve the conveyance of chips and iron powder, but not limited thereto, a weak magnetic material with a magnetic permeability of 1.01 to 5500, or within 3.5 mm A thin iron plate may be used.

また、この発明によれば、鉄芯の溝に挿通する第１の巻線、第２の巻線又は第３の巻線は、位相の異なる交流電流、例えば、二相又は三相交流の電流が流れることによって位相をずらして合成磁界を発生させ、この合成磁界が時間とともに移動する移動磁界を形成することになるから、切粉・鉄粉は搬送面に沿って搬送される。これによって、簡単な構造で切粉・鉄粉を外部に排出させることができる。   Further, according to the present invention, the first winding, the second winding, or the third winding that is inserted into the groove of the iron core has an alternating current having a different phase, for example, a two-phase or three-phase alternating current. As a result, the resultant magnetic field is generated by shifting the phase, and the resultant magnetic field forms a moving magnetic field that moves with time, so that the chips and iron powder are transported along the transport surface. This makes it possible to discharge the chips and iron powder to the outside with a simple structure.

また、この発明によれば、成形機械によって切削される切粉は、その切削物しだいによりその大きさが変化する。大きさが異なる切粉に対して、第１の巻線ピッチ、第２の巻線ピッチ、又は第３の巻線ピッチを可変とすれば、つまり、各巻線を各巻線が挿通する溝の位置をずらして巻回すれば、切粉の大きさにバラツキがあっても１個の搬送装置で切粉を最適の速度で搬送することができる。   In addition, according to the present invention, the size of the chips cut by the molding machine changes depending on the cut material. If the first winding pitch, the second winding pitch, or the third winding pitch is variable for chips of different sizes, that is, the position of the groove through which each winding passes. If the windings are shifted, the chips can be conveyed at an optimum speed with a single conveying device even if the sizes of the chips vary.

さらに、この発明の切粉・鉄粉搬送装置は、前記鉄芯の切粉搬送方向に沿って、順に、吸入部、搬送部、排出部が形成されている。吸入部に直流電流を流し、搬送部に交流電流を流すことによって、吸入部においては、その磁力によって切粉を集めることができ、搬送部においては移動磁界によって切粉や鉄粉を順に搬送させることができる。この際、吸入部には所定のタイミングで交流電流を流すように回路構成することによって、吸入部に集められた切粉や鉄粉は移動磁界によって搬送され、その後搬送部によって排出部に向かって搬送されることとなる。   Furthermore, in the chip / iron powder conveying device of the present invention, a suction part, a conveying part, and a discharging part are formed in this order along the iron chip's chip conveying direction. By flowing a direct current through the suction unit and an alternating current through the transport unit, the suction unit can collect chips by its magnetic force, and the transport unit sequentially transports chips and iron powder by a moving magnetic field. be able to. At this time, by configuring the circuit so that an alternating current flows through the suction portion at a predetermined timing, the chips and iron powder collected in the suction portion are transported by the moving magnetic field, and then toward the discharge portion by the transport portion. It will be transported.

また、排出部に搬送された切粉や鉄粉は、一旦排出部に溜められることとなるが、排出部が消磁されることによって簡単に外部に排出させることができる。   Moreover, although the chip | tip and iron powder conveyed by the discharge part will be once stored in a discharge part, they can be easily discharged | emitted by demagnetizing a discharge part.

この発明の切粉・鉄粉分離搬送システムによれば、成形機械で削られた切粉・鉄粉は、冷却水とともにポンプによってタンク内に回収される。タンク内では、切粉・鉄粉は切粉・鉄粉搬送装置によって搬送されて外部に排出される。この搬送装置は、請求項１に記載した構成と同様であり、位相の異なる交流電流を流すことによって発生する移動磁界で、タンク内の切粉・鉄粉をすべて吸引して搬送することから、タンク内を２分割に形成する必要はなく簡単に構成できる。また、高価なセパレータを使用することなく切粉・鉄粉を分離することができることから、切粉・鉄粉搬送装置も請求項１と同様の効果を達成することができる。   According to the chip / iron powder separating and conveying system of the present invention, the chip / iron powder shaved by the molding machine is collected in the tank by the pump together with the cooling water. In the tank, the chips and iron powder are transported by the chip and iron powder transport device and discharged to the outside. This transport device is the same as the configuration described in claim 1, and in the moving magnetic field generated by flowing alternating currents having different phases, all the chips and iron powder in the tank are sucked and transported, The tank does not need to be divided into two parts and can be configured easily. Further, since the chips and iron powder can be separated without using an expensive separator, the chip and iron powder conveying device can also achieve the same effect as that of the first aspect.

次に、一形態の切粉・鉄粉分離搬送システム及び切粉・鉄粉搬送装置の詳細を図面に基づいて説明する。   Next, details of one embodiment of the chip / iron powder separating and conveying system and the chip / iron powder conveying device will be described with reference to the drawings.

In the embodiment, a combined magnetic field is generated in the coil 13 by flowing a three-phase alternating current. That is, as shown in FIG. 2, the grooves 111 a, 111 b, 111 c, 111 ′ a, 111 ′ b, 111 ′ c... Formed in the iron core 11 have a first winding 131 a and a second winding, respectively.

The second winding 131b is, for example, a three-phase alternating current W-phase coil 13W, and the third winding 131c is, for example, a three-phase alternating current V-phase coil 13V, and is similar to the W-phase and V-phase. They are arranged sequentially.

なお、図４における右側から順に１個のＵ相コイル１３Ｕ、１個のＷ相コイル１３Ｗ、１個のＶ相コイル１３Ｖを配置してコイル組１４を構成する。隣接するコイル組１４どうしにおける各相のコイルは、各相におけるコイル１３の巻き方向をそれぞれ逆にして順に配置されている。さらに、端末のコイル組１４におけるＵ相とＶ相における巻き始め側は電源Ｅ側に接続するとともに、Ｗ相における巻き終わり側が電源Ｅ側に接続されている。また、左端のコイル組１４は中点結線されている。   In addition, one U-phase coil 13U, one W-phase coil 13W, and one V-phase coil 13V are arranged in order from the right side in FIG. The coils of each phase in the adjacent coil sets 14 are arranged in order with the winding direction of the coil 13 in each phase reversed. Further, the winding start side in the U phase and the V phase in the coil set 14 of the terminal is connected to the power supply E side, and the winding end side in the W phase is connected to the power supply E side. Further, the leftmost coil set 14 is connected at a midpoint.

コイル１３を巻回した鉄芯１１は、図２に示すように、角筒状に形成されたケース体１５内に挿入されて鉄粉搬送装置１０を構成する。ケース体１５は、電気抵抗の高い非磁性材、例えば、ステンレス製で形成され、図２における鉄芯１１の上方に位置する面を搬送面１５１として形成する。   As shown in FIG. 2, the iron core 11 around which the coil 13 is wound is inserted into a case body 15 formed in a rectangular tube shape to constitute the iron powder conveying device 10. The case body 15 is formed of a non-magnetic material having high electrical resistance, for example, stainless steel, and forms a surface located above the iron core 11 in FIG.

このケース体１５は、非磁性材以外に、弱磁性材、あるいは、磁性材であれば薄い厚みの鉄板であってもよい。弱磁性材の場合、透磁率１．０１〜５５００（望ましくは、１．０１〜１０００）の範囲であればよく、この範囲は、例えば、ステンレス製のケース体の表面を研削加工して磁性を帯びることを含むものである。   The case body 15 may be a weak magnetic material or a thin iron plate as long as it is a magnetic material, in addition to a non-magnetic material. In the case of a weak magnetic material, the magnetic permeability may be in the range of 1.01 to 5500 (preferably 1.01 to 1000). For example, this range is obtained by grinding the surface of a stainless steel case body to obtain magnetism. Includes tingling.

また、薄板状の鉄板の場合は、その厚みが３．５ｍｍ以下のものであれば、切粉が留まらず搬送可能となる結果が実験により示されている。   In addition, in the case of a thin plate-like iron plate, an experiment has shown that the chips can be conveyed without remaining if the thickness is 3.5 mm or less.

さらに、ケース体１５は、角筒状でなくても平板であってもよい。   Furthermore, the case body 15 may not be a rectangular tube shape but may be a flat plate.

次に、上記のように構成された鉄粉搬送装置１０及び分離搬送システム１の作用について説明する。   Next, the operation of the iron powder transfer device 10 and the separation transfer system 1 configured as described above will be described.

コイル１３に三相交流電流を流すと、図５に示すように、第１の巻線１３１ａ（Ｕ相コイル１３Ｕ）と第２の巻線１３１ｂ（Ｗ相コイル１３Ｗ）及び第３の巻線１３１ｃ（Ｖ相コイル１３Ｖ）は、それぞれ１２０度位相がずれた正弦波形を描くこととなる。例えば、図５において時間ｔとともに経過する３位置を選択し、それぞれの位置を時点Ｐ１、Ｐ２、Ｐ３とすると、時点Ｐ１、Ｐ２、Ｐ３における合成磁界は、図６に示すように表される。つまり、それぞれの時点Ｐ１、Ｐ２、Ｐ３における最大磁力がずれることとなるから、これが時間とともに移動する移動磁界となって鉄粉搬送装置１０の搬送面１５１に載った鉄粉は搬送されることとなる。搬送された鉄粉は鉄粉搬送装置１０の他端で外部に配置された図示しない鉄粉受け皿に落下される。   When a three-phase alternating current is passed through the coil 13, as shown in FIG. 5, the first winding 131a (U-phase coil 13U), the second winding 131b (W-phase coil 13W), and the third winding 131c. (V-phase coil 13V) draws sinusoidal waveforms that are 120 degrees out of phase. For example, if three positions that elapse with time t in FIG. 5 are selected and the respective positions are designated as time points P1, P2, and P3, the combined magnetic fields at time points P1, P2, and P3 are represented as shown in FIG. That is, since the maximum magnetic force at each time point P1, P2, and P3 is shifted, this becomes a moving magnetic field that moves with time, and the iron powder placed on the conveying surface 151 of the iron powder conveying apparatus 10 is conveyed. Become. The conveyed iron powder is dropped to an iron powder tray (not shown) disposed outside at the other end of the iron powder conveying device 10.

一方、実施形態においては、鉄粉搬送装置１０は、図７に示すように、３部位を形成している。例えば、タンク７内に位置する部位の一端を吸引部１０１とし、吸引部１０１に連接する鉄粉搬送路を搬送部１０２とし、他端に配置して鉄粉を外部に排出する部位を排出部１０３とする。   On the other hand, in embodiment, the iron powder conveying apparatus 10 forms 3 site | parts, as shown in FIG. For example, one end of the part located in the tank 7 is the suction part 101, the iron powder transport path connected to the suction part 101 is the transport part 102, and the part that is disposed at the other end and discharges the iron powder to the outside is the discharge part. 103.

吸入部１０１と排出部１０３とはそれぞれ短路に形成され、搬送部１０２は吸入部１０１と排出部１０３との間で長路に形成されている。そして、吸入部１０１には直流電流を流し、搬送部１０２、排出部１０３には三相の交流電流を流しておく。   The suction part 101 and the discharge part 103 are each formed in a short path, and the transport part 102 is formed in a long path between the suction part 101 and the discharge part 103. Then, a direct current is passed through the suction part 101, and a three-phase alternating current is passed through the transport part 102 and the discharge part 103.

そして、吸入部１０１に鉄粉が集められると、直流電流を三相交流電流に切り換えて吸入部１０１に溜められた鉄粉を搬送部１０２に向けて搬送させる。搬送部１０２では、三相交流電流が流れていることからやはり移動磁界によって鉄粉を排出部１０３に向かって搬送することとなる。排出部１０３では、当初、三相交流電流が流れていることから搬送された鉄粉は排出部１０３の端部まで搬送され、端部で一旦溜められる。そして、排出部１０３に流れている交流電流を次第に弱めることによって排出部１０３を消磁状態にする。これによって、排出部１０３の端部に溜められていた鉄粉を外部に落下させて排出することになる。   When the iron powder is collected in the suction unit 101, the direct current is switched to a three-phase alternating current, and the iron powder stored in the suction unit 101 is transported toward the transport unit 102. In the conveyance part 102, since the three-phase alternating current flows, iron powder will also be conveyed toward the discharge part 103 by a moving magnetic field. In the discharge part 103, since the three-phase alternating current flows initially, the conveyed iron powder is conveyed to the edge part of the discharge part 103, and is temporarily collected by the edge part. And the discharge part 103 is made into a demagnetization state by weakening the alternating current which is flowing into the discharge part 103 gradually. As a result, the iron powder stored at the end of the discharge portion 103 is dropped and discharged.

なお、吸引部１０１と搬送部１０２との間には、例えば、リレーを配置させて、所定のタイミングで直流電流から三相交流電流に回路を切り換えるようにしておく。そして直流電流を流すことによって、磁力を増大できることから、タンク７内の多量の鉄粉を搬送部１０２に移動しやすくし、三相交流電流に切り換えることによって移動磁界を発生させて鉄粉を搬送することとなる。   Note that, for example, a relay is disposed between the suction unit 101 and the transport unit 102, and the circuit is switched from a direct current to a three-phase alternating current at a predetermined timing. Since the magnetic force can be increased by flowing a direct current, a large amount of iron powder in the tank 7 can be easily moved to the transport unit 102, and the magnetic field is generated by switching to a three-phase alternating current to transport the iron powder. Will be.

この際、吸引部１０１は、鉄粉を搬送部１０２上に、容易に移動させやすいように、傾斜面１０１ａに形成することが望ましい。また、排出部１０３は、消磁することによって鉄粉を落下しやすいように搬送部１０２に対して下方に傾斜して形成することが望ましい。   At this time, the suction unit 101 is desirably formed on the inclined surface 101 a so that the iron powder can be easily moved onto the transport unit 102. Further, it is desirable that the discharge unit 103 is formed to be inclined downward with respect to the transport unit 102 so that the iron powder can easily fall by demagnetization.

さらに、図８に示すように、搬送装置１０Ａの排出部１０３Ａ部位を折り返して略「つ」字状に形成するとともに、排出部１０３Ａを上方から下方にむけるように、鉄粉搬送装置１０Ａを縦長状に配置してもよい。この場合、搬送された鉄粉は吸入部１０１Ａから搬送部１０２Ａを通り、排出部１０３Ａに進入した後、排出部１０３Ａを消磁状態にすることによって吸引力がなくなるから、自重で落下しやすくなる。   Further, as shown in FIG. 8, the discharge portion 103 </ b> A portion of the transfer device 10 </ b> A is folded back to be formed in a substantially “T” shape, and the iron powder transfer device 10 </ b> A is vertically long so that the discharge portion 103 </ b> A is directed downward from above. You may arrange in a shape. In this case, the transported iron powder passes from the suction unit 101A through the transport unit 102A and enters the discharge unit 103A, and then the discharge unit 103A is demagnetized so that the suction force is lost.

なお、実施形態では吸入部１０１（１０１Ａ）に直流電流を流して、所定のタイミングで三相交流電流に切り換えるようにしているが、吸入部１０１（１０１Ａ）に三相交流電流を流したままにしておいてもよく、また、直流電流と三相交流電流とを切り換えることなく直流電流で鉄粉を搬送させるようにしてもよい。   In the embodiment, a direct current is passed through the suction part 101 (101A) and switched to a three-phase alternating current at a predetermined timing. However, the three-phase alternating current is kept flowing through the suction part 101 (101A). Alternatively, the iron powder may be conveyed by a direct current without switching between the direct current and the three-phase alternating current.

また、成形機械が切削機であって、切削される切粉に大きさの相異がある場合、鉄芯１１の溝部１１１を挿通する巻線のピッチを変えることができる。例えば、図９に示すように、鉄芯１１の溝部には、２種類のコイル１３の巻線１３１、１３２を交互に挿通する。つまり、鉄芯１１の溝部１１１には、順次、Ａ種の第１の巻線１３１ａ、Ｂ種の第１の巻線１３２ａ、Ａ種の第２の巻線１３１ｂ、Ｂ種の第２の巻線１３２ｂ、Ａ種の第３の巻線１３１ｃ、Ｂ種の第３の巻線１３２ｃ、…を挿通させて巻回する。これによって、巻線１３１の溝部挿入間ピッチを変えることができ、切粉の大きさに合わせることができる。   Moreover, when the molding machine is a cutting machine and the chips to be cut have different sizes, the pitch of the windings that pass through the groove 111 of the iron core 11 can be changed. For example, as shown in FIG. 9, windings 131 and 132 of two types of coils 13 are alternately inserted into the groove portion of the iron core 11. That is, in the groove portion 111 of the iron core 11, the A type first winding 131 a, the B type first winding 132 a, the A type second winding 131 b, and the B type second winding are sequentially provided. The wire 132b, the A type third winding 131c, the B type third winding 132c,... Are inserted and wound. Thereby, the pitch between the groove portions of the winding 131 can be changed, and the size of the chips can be adjusted.

上述のように、実施形態の鉄粉搬送装置１０は、細長状の鉄芯１１に搬送方向に沿って溝部１１１を並設して形成し、溝部１１１に挿通したコイル１３に三相交流電流を流すことによって移動磁界を発生させることができることから、非磁性材で形成された搬送面１５１上で鉄粉を搬送させることができる。これによって高価なオイルセパレータを使用しないで鉄粉を分離除去できることから廉価でメンテナンスフリーの鉄粉搬送装置１０及び鉄板分離搬送システム１を提供することができる。   As described above, the iron powder transfer device 10 of the embodiment is formed by arranging the groove portion 111 side by side along the transfer direction in the elongated iron core 11, and applying a three-phase alternating current to the coil 13 inserted through the groove portion 111. Since a moving magnetic field can be generated by flowing, iron powder can be conveyed on the conveyance surface 151 formed of a nonmagnetic material. As a result, the iron powder can be separated and removed without using an expensive oil separator, so that it is possible to provide an inexpensive and maintenance-free iron powder conveyance device 10 and the iron plate separation and conveyance system 1.

なお、本発明の切粉・鉄粉の搬送装置及び分離搬送システムは、上記の形態に限定するものではない。例えば、コイルに流す電流を三相交流電流でなく二相の交流電流を流すようにしてもよい。この場合、二相交流は単相交流にコンデンサを入れて作り出すことができる。   Note that the chip / iron powder conveying device and the separation conveying system of the present invention are not limited to the above-described embodiments. For example, the current flowing through the coil may be a two-phase AC current instead of a three-phase AC current. In this case, a two-phase alternating current can be created by inserting a capacitor into the single-phase alternating current.

さらに、搬送面を形成する非磁性材のケース体は、電気抵抗の高い材料であれば、ステンレス材に限定するものではない。   Furthermore, the case body of the non-magnetic material that forms the transport surface is not limited to a stainless steel material as long as it has a high electrical resistance.

また、コイルに流す交流電流は、位相の異なる交流電流であれば、二相交流電流や三相交流電流以外でもよい。   Further, the alternating current that flows through the coil may be other than the two-phase alternating current or the three-phase alternating current as long as the alternating current has a different phase.
