Description
本発明は、異なる磁極が螺旋状に形成された複数の磁性体を有するローラコンベヤに関する。 The present invention relates Carlo Rakonbeya which having a plurality of magnetic bodies different magnetic poles are formed in a spiral shape.
従来、磁気的な引力あるいは反発力を利用した駆動装置としては、周方向に向けてＮ極およびＳ極とが交互に形成された外周面を有する円筒状の第１磁性体を備えている。そして、外周面にＮ極およびＳ極が交互に軸方向に向けて螺旋状に形成された円筒状の第２磁性体の回転軸方向を、第１磁性体の回転軸方向に直交させた状態で、この第１磁性体の下方に非接触な状態で第２磁性体が回転可能に取り付けられている。この第２磁性体の外周面に形成されているＮ極およびＳ極は、第１磁性体の外周面に形成されたＮ極およびＳ極のピッチに対応した螺旋ピッチで設けられている。 Conventionally, a drive device using magnetic attraction or repulsion includes a cylindrical first magnetic body having an outer peripheral surface in which N and S poles are alternately formed in the circumferential direction. A state in which the rotation axis direction of the cylindrical second magnetic body in which the N pole and the S pole are alternately formed in the axial direction on the outer peripheral surface is orthogonal to the rotation axis direction of the first magnetic body Thus, the second magnetic body is rotatably attached below the first magnetic body in a non-contact state. The N pole and S pole formed on the outer peripheral surface of the second magnetic body are provided at a helical pitch corresponding to the pitch of the N pole and S pole formed on the outer peripheral surface of the first magnetic body.
そして、この第２磁性体を回転させることにより、この第２磁性体の外周面に設けられているＮ極およびＳ極と、第１磁性体の外周面に設けられているＮ極およびＳ極との間の磁気的な引力および反発力、すなわちこれら第１磁性体と第２磁性体とのＮ極とＳ極とが最も近接した状態で引き合う状態を維持しようとする作用によって、この第２磁性体の回転に伴って第１回転体が回転する構成が記載されている(例えば、特許文献１参照。)。 And by rotating this 2nd magnetic body, the N pole and S pole provided in the outer peripheral surface of this 2nd magnetic body, and the N pole and S pole provided in the outer peripheral surface of the 1st magnetic body The magnetic attractive force and the repulsive force between the first magnetic body and the second magnetic body, that is, the action of trying to maintain the state in which the N pole and the S pole of the first magnetic body and the second magnetic body are attracted in the closest state. A configuration is described in which the first rotating body rotates as the magnetic body rotates (see, for example, Patent Document 1).
ところが、この駆動装置では、第１磁性体あるいは従動磁気車の回転軸と、第２磁性体あるいは内側磁気車の回転軸とを直交させており、これら第１磁性体あるいは従動磁気車と、第２磁性体あるいは内側磁気車とが最も近接した状態で引き合う状態を維持しようとする場合であっても、第２磁性体あるいは内側磁気車の外周面にＮ極およびＳ極が螺旋状に形成されている。このため、これら第１磁性体あるいは従動磁気車と、第２磁性体あるいは内側磁気車との間でわずかな反発力が発生してしまうから、この反発力によって第２磁性体あるいは内側磁気車の回転に伴う第１磁性体あるいは従動磁気車の回転力が劣ってしまう。さらに、第２磁性体あるいは内側磁気車の外周面にＮ極およびＳ極を螺旋状に形成させているため、この第２磁性体あるいは内側磁気車の構造が複雑である。 However, in this drive device, the rotation axis of the first magnetic body or the driven magnetic wheel and the rotation axis of the second magnetic body or the inner magnetic wheel are orthogonal to each other. Even when trying to maintain the state of attracting the two magnetic bodies or the inner magnetic wheel in the closest state, the N pole and the S pole are spirally formed on the outer peripheral surface of the second magnetic body or the inner magnetic wheel. ing. For this reason, a slight repulsive force is generated between the first magnetic body or the driven magnetic wheel and the second magnetic body or the inner magnetic wheel. Therefore, the repulsive force causes the second magnetic body or the inner magnetic wheel to move. The rotational force of the first magnetic body or the driven magnetic wheel accompanying the rotation is inferior. Further, since the N pole and the S pole are spirally formed on the outer peripheral surface of the second magnetic body or the inner magnetic wheel, the structure of the second magnetic body or the inner magnetic wheel is complicated.
そこで、この種の駆動装置を備えた磁力駆動コンベヤとしては、Ｎ極およびＳ極が交互に軸方向に向けて螺旋状に形成された外周面を有する円筒状の伝達用磁気車を複数備えている。そして、これら伝達用磁気車それぞれは、これら伝達用磁気車それぞれの外周面を平行に対向させた状態で、これら伝達用磁気車のそれぞれを搬送物を搬送する搬送方向に向けて等間隔に離間させて並設させている。さらに、これら伝達用磁気車は、これら伝達用磁石の外周面間に形成される磁力によって、いずれか一の伝達用磁気車を回転させると、このいずれか一の伝達用磁気車に並設されている他の伝達用磁気車が、いずれか一の伝達用磁気車を追従するように、このいずれか一の伝達用磁気車と同じ方向に回転する構成が知られている(例えば、特許文献２参照。)。
しかしながら、上述した磁気駆動コンベヤでは、各伝達用磁気車の外周面に同様の磁極を螺旋状に形成させているため、これら各伝達用磁気車それぞれを連動させて回転させた際に、これら各伝達用磁気車のそれぞれに軸方向に沿った力が作用してしまう。したがって、これら伝達用磁気車それぞれを連動させて回転させた際に、これら伝達用磁気車のそれぞれが軸方向に向けて移動してしまうという問題を有している。 However, in the magnetically driven conveyor described above, the same magnetic poles are spirally formed on the outer peripheral surface of each transmission magnetic wheel. Therefore, when each of these transmission magnetic wheels is rotated in conjunction with each other, A force along the axial direction acts on each of the transmission magnetic wheels. Therefore, when the transmission magnetic wheels are rotated in conjunction with each other, there is a problem in that each of the transmission magnetic wheels moves in the axial direction.
本発明は、このような点に鑑みなされたもので、各磁性体が移動しにくいローラコンベヤを提供することを目的とする。 The present invention has been made in view of the above problems, and an object thereof is the magnetic body to provide a mobile and difficulty Iro Rakonbeya.
請求項１記載のローラコンベヤは、一方の軸方向に向けて異なる磁極が交互に螺旋状に形成された外周面を有し、中心軸を中心として回転可能な筒状の第１の磁性体と、この第１の磁性体の外周面に形成されている磁極とは逆の方向である他方の軸方向に向けて異なる磁極が交互に螺旋状に形成された外周面を有し、この第１の磁性体の軸方向に沿った一端面に一端面を同心状に対向させた状態で、この第１の磁性体と同軸に固定され、中心軸を中心として回転可能な筒状の第２の磁性体と、前記第１の磁性体の外周面に形成されている磁極と同様の磁極が形成された外周面を有し、この外周面を前記第１の磁性体の外周面に略平行に対向させた状態で、前記第１の磁性体の回転方向と同じ方向に中心軸を中心として回転可能な筒状の第３の磁性体と、前記第２の磁性体の外周面に形成されている磁極と同様の磁極が形成された外周面を有し、この外周面を前記第２の磁性体の外周面に略平行に対向させ、かつ前記第３の磁性体の軸方向に沿った一端面に一端面を同心状に対向させた状態で、この第３の磁性体と同軸に固定され、前記第２の磁性体の回転方向と同じ方向に中心軸を中心として回転可能な筒状の第４の磁性体と、前記第２の磁性体および前記第４の磁性体に同心状に取り付けられ、搬送方向に沿って並設され、搬送物を搬送方向に搬送する複数の搬送ローラとを具備したものである。 The roller conveyor according to claim 1 has a cylindrical first magnetic body that has an outer peripheral surface in which different magnetic poles are alternately formed spirally in one axial direction, and is rotatable about a central axis. The first magnetic body has an outer peripheral surface in which different magnetic poles are alternately formed in a spiral direction toward the other axial direction that is opposite to the magnetic pole formed on the outer peripheral surface of the first magnetic body. A second cylindrical member fixed coaxially with the first magnetic body and rotatable about the central axis with one end face concentrically opposed to one end face along the axial direction of the magnetic body. A magnetic body and an outer peripheral surface on which a magnetic pole similar to the magnetic pole formed on the outer peripheral surface of the first magnetic body is formed. The outer peripheral surface is substantially parallel to the outer peripheral surface of the first magnetic body. while being opposed, said rotatable cylindrical third in the same direction as the rotation direction of the first magnetic body about a central axis And an outer peripheral surface on which a magnetic pole similar to the magnetic pole formed on the outer peripheral surface of the second magnetic body is formed. The outer peripheral surface is substantially parallel to the outer peripheral surface of the second magnetic body. With the one end face concentrically opposed to the one end face along the axial direction of the third magnetic body, the first magnetic body is fixed coaxially with the third magnetic body, A cylindrical fourth magnetic body that is rotatable about the central axis in the same direction as the rotation direction, and is attached concentrically to the second magnetic body and the fourth magnetic body, and arranged in parallel along the transport direction. And a plurality of transport rollers for transporting the transported object in the transport direction .
そして、一方の軸方向に向けて異なる磁極が交互に螺旋状に形成された外周面を有する第１の磁性体を回転させることにより、この第１の磁性体の外周面に形成されている磁極と同様の磁極が形成された外周面を有する第３の磁性体が、第１の磁性体の回転方向と同じ方向に回転する。このとき、これら第１の磁性体の外周面と第３の磁性体の外周面との間に作用する磁力によって、これら第１の磁性体および第３の磁性体のそれぞれに対して、これら第１の磁性体および第３の磁性体の一方の軸方向に向う力が作用する。さらに、この第１の磁性体の外周面に形成されている磁極とは逆の方向である他方の軸方向に向けて異なる磁極が交互に螺旋状に形成された外周面を有する第２の磁性体を回転させることにより、この第２の磁性体の外周面に形成されている磁極と同様の磁極が形成された外周面を有する第４の磁性体が、第２の磁性体の回転方向と同じ方向に回転する。このとき、これら第２の磁性体の外周面と第４の磁性体の外周面との間に作用する磁力によって、これら第２の磁性体および第４の磁性体のそれぞれに対して、これら第２の磁性体および第４の磁性体の他方の軸方向に向う力が作用する。ここで、これら第１の磁性体の一端面に第２の磁性体の一端面を同心状に対向させた状態で、これら第１の磁性体および第２の磁性体を同軸に固定するとともに、第３の磁性体の一端面に第４の磁性体の一端面を同心状に対向させた状態で、これら第３の磁性体および第４の磁性体を同軸に固定した。この結果、これら第１の磁性体および第２の磁性体のそれぞれを同じ方向に回転させた際に、第１の磁性体と第３の磁性体との間の磁力にて作用する一方の軸方向に向う力と、第２の磁性体と第４の磁性体との間の磁力にて作用する他方の軸方向に向う力とが打ち消し合うように作用する。このため、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体のそれぞれを連動させて同じ方向に回転させた際に、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体が軸方向に移動しにくくなる。 And the magnetic pole formed in the outer peripheral surface of this 1st magnetic body is rotated by rotating the 1st magnetic body which has the outer peripheral surface in which the different magnetic pole was formed in the spiral shape alternately toward one axial direction. The third magnetic body having the outer peripheral surface on which the same magnetic pole is formed rotates in the same direction as the rotation direction of the first magnetic body. At this time, each of the first magnetic body and the third magnetic body is caused by the magnetic force acting between the outer peripheral surface of the first magnetic body and the outer peripheral surface of the third magnetic body. A force directed in one axial direction of the first magnetic body and the third magnetic body acts. Further, the second magnetic material having an outer peripheral surface in which different magnetic poles are alternately formed in a spiral shape toward the other axial direction which is the opposite direction to the magnetic pole formed on the outer peripheral surface of the first magnetic body. By rotating the body, a fourth magnetic body having an outer peripheral surface on which a magnetic pole similar to the magnetic pole formed on the outer peripheral surface of the second magnetic body is formed becomes the rotational direction of the second magnetic body. Rotate in the same direction. At this time, the second magnetic body and the fourth magnetic body are respectively affected by the magnetic force acting between the outer peripheral surface of the second magnetic body and the outer peripheral surface of the fourth magnetic body. A force directed in the other axial direction of the second magnetic body and the fourth magnetic body acts. Here, in a state where one end surface of the second magnetic body is concentrically opposed to one end surface of the first magnetic body, the first magnetic body and the second magnetic body are fixed coaxially, The third magnetic body and the fourth magnetic body were coaxially fixed with one end face of the fourth magnetic body concentrically opposed to one end face of the third magnetic body. As a result, when the first magnetic body and the second magnetic body are rotated in the same direction, one shaft acting by the magnetic force between the first magnetic body and the third magnetic body. The force acting in the direction and the force acting in the other axial direction acting by the magnetic force between the second magnetic body and the fourth magnetic body act so as to cancel each other. Therefore, when the first magnetic body, the second magnetic body, the third magnetic body, and the fourth magnetic body are interlocked and rotated in the same direction, the first magnetic body, the second magnetic body, The second magnetic body, the third magnetic body, and the fourth magnetic body are less likely to move in the axial direction.
請求項２記載のローラコンベヤは、請求項１記載のローラコンベヤにおいて、第１の磁性体の外周面と第３の磁性体の外周面との間の磁力は、第２の磁性体の外周面と第４の磁性体の外周面との間の磁力に等しいものである。 Roller conveyor according to claim 2, wherein, in the roller conveyor of claim 1, wherein, the magnetic force between the outer peripheral surface and the outer peripheral surface of the third magnetic body of the first magnetic body, the outer peripheral surface of the second magnetic body And the magnetic force between the outer peripheral surface of the fourth magnetic body.
そして、第１の磁性体の外周面と第３の磁性体の外周面との間の磁力を、第２の磁性体の外周面と第４の磁性体の外周面との間の磁力に等しくした。この結果、これら第１の磁性体および第２の磁性体のそれぞれを同じ方向に回転させた際に、第１の磁性体と第３の磁性体との間の磁力にて作用する一方の軸方向に向う力と、第２の磁性体と第４の磁性体との間の磁力にて作用する他方の軸方向に向う力とが同じになる。このため、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体のそれぞれを連動させて同じ方向に回転させた際に、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体が軸方向に移動しなくなる。 The magnetic force between the outer peripheral surface of the first magnetic body and the outer peripheral surface of the third magnetic body is equal to the magnetic force between the outer peripheral surface of the second magnetic body and the outer peripheral surface of the fourth magnetic body. did. As a result, when the first magnetic body and the second magnetic body are rotated in the same direction, one shaft acting by the magnetic force between the first magnetic body and the third magnetic body. The force directed in the direction and the force directed in the other axial direction acting by the magnetic force between the second magnetic body and the fourth magnetic body are the same. Therefore, when the first magnetic body, the second magnetic body, the third magnetic body, and the fourth magnetic body are interlocked and rotated in the same direction, the first magnetic body, the second magnetic body, The second magnetic body, the third magnetic body, and the fourth magnetic body do not move in the axial direction.
請求項３記載のローラコンベヤは、請求項１または２記載のローラコンベヤにおいて、第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体のそれぞれは、等しい大きさの円筒状に形成され、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体それぞれの外周面には、異なる磁極が等間隔に形成されているものである。 Roller conveyor according to claim 3, wherein, in the roller conveyor of claim 1, wherein the first magnetic body, second magnetic body, each of the third magnetic body and the fourth magnetic equal size The magnetic poles are formed at equal intervals on the outer peripheral surfaces of the first magnetic body, the second magnetic body, the third magnetic body, and the fourth magnetic body. is there.
そして、第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体のそれぞれを等しい大きさの円筒状に形成し、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体それぞれの外周面に異なる磁極を等間隔に形成した。この結果、第１の磁性体と第３の磁性体との間の磁力が、第２の磁性体と第４の磁性体との間の磁力に等しくなる。よって、これら第１の磁性体および第２の磁性体のそれぞれを同じ方向に回転させた際に、第１の磁性体および第３の磁性体に作用する一方の軸方向に向う力が、第２の磁性体および第４の磁性体に作用する他方の軸方向に向う力と同じになる。このため、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体のそれぞれを連動させて同じ方向に回転させた際に、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体が軸方向に移動しなくなる。 Each of the first magnetic body, the second magnetic body, the third magnetic body, and the fourth magnetic body is formed into a cylindrical shape having the same size, and the first magnetic body and the second magnetic body are formed. Different magnetic poles were formed at equal intervals on the outer peripheral surfaces of the third magnetic body and the fourth magnetic body. As a result, the magnetic force between the first magnetic body and the third magnetic body is equal to the magnetic force between the second magnetic body and the fourth magnetic body. Accordingly, when each of the first magnetic body and the second magnetic body is rotated in the same direction, the force in one axial direction acting on the first magnetic body and the third magnetic body is This is the same as the other axial force acting on the second magnetic body and the fourth magnetic body. Therefore, when the first magnetic body, the second magnetic body, the third magnetic body, and the fourth magnetic body are interlocked and rotated in the same direction, the first magnetic body, the second magnetic body, The second magnetic body, the third magnetic body, and the fourth magnetic body do not move in the axial direction.
請求項４記載のローラコンベヤは、請求項１または２記載のローラコンベヤにおいて、互いに離間対向する一対のコンベヤフレームを具備し、搬送ローラ、第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体のそれぞれは、等しい大きさの円筒状に形成され、前記両コンベヤフレーム間に配設されているものである。According to a fourth aspect of the present invention, there is provided the roller conveyor according to the first or second aspect, wherein the roller conveyor includes a pair of conveyor frames that are spaced apart from each other, and includes a transport roller, a first magnetic body, a second magnetic body, and a third Each of the magnetic body and the fourth magnetic body is formed in a cylindrical shape having the same size, and is disposed between the two conveyor frames.
本発明によれば、第１の磁性体および第２の磁性体のそれぞれを同じ方向に回転させた際に、第１の磁性体と第３の磁性体との間の磁力にて作用する一方の軸方向に向う力と、第２の磁性体と第４の磁性体との間の磁力にて作用する他方の軸方向に向う力とが打ち消し合うように作用するので、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体のそれぞれを連動させて同じ方向に回転させた際に、これら第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体を軸方向に移動しにくくでき、また、第１の磁性体、第２の磁性体、第３の磁性体および第４の磁性体を同一方向に連動させて回転できるから、これら第２の磁性体および第４の磁性体それぞれに取り付けられている搬送ローラのそれぞれを搬送方向に回転できる。 According to the present invention , when each of the first magnetic body and the second magnetic body is rotated in the same direction, it acts by the magnetic force between the first magnetic body and the third magnetic body. Since the force directed in the axial direction of the second magnetic body and the force directed in the other axial direction acting by the magnetic force between the second magnetic body and the fourth magnetic body act to cancel each other, these first magnetic When the body, the second magnetic body, the third magnetic body, and the fourth magnetic body are rotated in the same direction in conjunction with each other, the first magnetic body, the second magnetic body, the third magnetic body, The magnetic body and the fourth magnetic body can be made difficult to move in the axial direction, and the first magnetic body, the second magnetic body, the third magnetic body, and the fourth magnetic body are rotated in the same direction. Since each of the transport rollers attached to the second magnetic body and the fourth magnetic body can be moved in the transport direction. It can be rolling.
以下、本発明の一実施の形態を図面を参照して説明する。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
図１ないし図５において、１はローラコンベヤで、このローラコンベヤ１は、磁性連動装置としての駆動伝達装置である。そして、このローラコンベヤ１は、磁気的な引力あるいは反発力にて複数の搬送ローラ２のそれぞれを同一方向である搬送方向Ｆに向けて回転させる磁気駆動コンベヤとしてのマグネット駆動コンベヤである。また、このローラコンベヤ１は、細長略矩形状のコンベヤ本体３を有している。このコンベヤ本体３には、物品などの搬送物を搬送する搬送方向Ｆに沿って平坦な搬送面４が形成されている。 1 to 5, reference numeral 1 denotes a roller conveyor. The roller conveyor 1 is a drive transmission device as a magnetic interlocking device. And this roller conveyor 1 is a magnet drive conveyor as a magnetic drive conveyor which rotates each of the some conveyance roller 2 toward the conveyance direction F which is the same direction with a magnetic attractive force or a repulsive force. The roller conveyor 1 has an elongated, substantially rectangular conveyor body 3. A flat conveyance surface 4 is formed on the conveyor main body 3 along a conveyance direction F in which a conveyance object such as an article is conveyed.
そして、このコンベヤ本体３は、平行に対向して配設された一対のコンベヤフレーム５,６を備えている。これら一対のコンベヤフレーム５,６間は、所定間隔毎に図示しない横継部材にて接続されて連結されている。さらに、これら一対のコンベヤフレーム５,６には、脚体８などが取り付けられ所定の高さに位置するように形成されている。 The conveyor body 3 includes a pair of conveyor frames 5 and 6 disposed in parallel to face each other. The pair of conveyor frames 5 and 6 are connected and connected by a connecting member (not shown) at predetermined intervals. Further, the pair of conveyor frames 5 and 6 are formed with legs 8 and the like so as to be positioned at a predetermined height.
また、これら一対のコンベヤフレーム５,６の間には、細長円筒状のローラである複数の搬送ローラ２が周方向に向けて回転可能に橋し渡された状態で取り付けられている。これら搬送ローラ２は、コンベヤ本体３の搬送方向Ｆに直交する幅方向に軸方向を沿わせた状態でそれぞれが回転可能に取り付けられている。さらに、これら搬送ローラ２は、コンベヤ本体３の搬送方向Ｆに向けて等間隔に離間された状態で、このコンベヤ本体３の搬送面４の搬送方向Ｆに沿って並設されている。言い換えると、これら搬送ローラ２は、搬送方向Ｆに直交する自身の軸周りに回転自在とされている。 Between the pair of conveyor frames 5 and 6, a plurality of conveying rollers 2, which are elongated cylindrical rollers, are attached in a state of being bridged so as to be rotatable in the circumferential direction. Each of these transport rollers 2 is rotatably attached in a state where the axial direction is along the width direction orthogonal to the transport direction F of the conveyor body 3. Further, the transport rollers 2 are arranged side by side along the transport direction F of the transport surface 4 of the conveyor body 3 while being spaced apart at equal intervals toward the transport direction F of the conveyor body 3. In other words, the transport rollers 2 are rotatable around their own axes orthogonal to the transport direction F.
ここで、これら搬送ローラ２には、中心軸Ｃとしての回転中心となる軸体７が中心軸方向に沿った同心状に摺動可能に挿通されて取り付けられている。これら軸体７は、搬送ローラ２の中心に挿通されて、一対のコンベヤフレーム５,６それぞれの内側面に両端部がそれぞれ回転可能に軸支されて取り付けられている。 Here, a shaft body 7 serving as a center of rotation as the central axis C is inserted into and attached to the transport rollers 2 so as to be slidable concentrically along the central axis direction. These shaft bodies 7 are inserted through the center of the conveying roller 2 and attached to the inner side surfaces of the pair of conveyor frames 5 and 6 so that both end portions thereof are rotatably supported.
そして、これら搬送ローラ２の軸方向に沿った側面部である一端面2aのそれぞれには、短軸状の内側磁気車11が同心状に取り付けられている。これら内側磁気車11は、第２の磁性体としての第２磁気車12、あるいは第４の磁性体としての第４磁気車13として機能する。ここで、これら内側磁気車11は、これら内側磁気車11の周囲を構成する外周面11aに異なる磁極が交互に螺旋状に形成された円筒状の永久磁石である。さらに、これら内側磁気車11は、搬送ローラ２の外径寸法に等しい外径寸法を有している。また、これら内側磁気車11は、これら内側磁気車11の軸方向に沿った一端面である内側面11bを搬送ローラ２の一端面2aに同軸状に対向させた状態で、これら搬送ローラ２に固定されて一体構造とされている。 A short-axis inner magnetic wheel 11 is concentrically attached to each of the one end surface 2a which is a side surface portion along the axial direction of the transport roller 2. These inner magnetic wheels 11 function as a second magnetic wheel 12 as a second magnetic body or a fourth magnetic wheel 13 as a fourth magnetic body. Here, the inner magnetic wheels 11 are cylindrical permanent magnets in which different magnetic poles are alternately formed in a spiral shape on the outer peripheral surface 11a constituting the periphery of the inner magnetic wheels 11. Further, these inner magnetic wheels 11 have an outer diameter dimension equal to the outer diameter dimension of the transport roller 2. The inner magnetic wheels 11 are disposed on the conveying rollers 2 with the inner surface 11b, which is one end surface along the axial direction of the inner magnetic wheels 11, facing the one end surface 2a of the conveying roller 2 coaxially. It is fixed and has a single structure.
よって、これら内側磁気車11にもまた、軸体７が中心軸方向に沿って同心状に挿通された状態で固定されている。このため、これら内側磁気車11は、軸体７の同一軸芯として取り付けられており、この軸体７の中心軸Ｃを回転中心として回転可能とされている。すなわち、これら内側磁気車11は、これら内側磁気車11の内側面11bを、各搬送ローラ２の一端面2aに同心状に当接させた状態で、これら搬送ローラ２それぞれに軸体７を介して固定されている。したがって、これら内側磁気車11は、これら内側磁気車11の回転によって各搬送ローラ２が回転する。 Therefore, the shaft body 7 is also fixed to these inner magnetic wheels 11 in a state of being inserted concentrically along the central axis direction. For this reason, these inner magnetic wheels 11 are attached as the same axis of the shaft body 7, and are rotatable around the central axis C of the shaft body 7. In other words, these inner magnetic wheels 11 have the inner side surfaces 11b of these inner magnetic wheels 11 in contact with one end surface 2a of each conveying roller 2 concentrically with each conveying roller 2 via the shaft 7. Is fixed. Accordingly, in the inner magnetic wheels 11, the transport rollers 2 are rotated by the rotation of the inner magnetic wheels 11.
また、これら内側磁気車11は、これら内側磁気車11の互いの外周面11a間を非接触な状態、すなわち所定の間隙を介した状態で対向させており、搬送方向Ｆに向けて直線状に並べられている。言い換えると、これら内側磁気車11は、これら内側磁気車11の軸方向である軸芯を互いに平行にした状態で、搬送方向Ｆに沿って並設されている。さらに、これら内側磁気車11は、これら内側磁気車11にて形成される磁界によって、これら内側磁気車11に近接して設置されている内側磁気車11を連動させて回転できる程度に、これら内側磁気車11間が離間されて軸間距離が設定されている。 The inner magnetic wheels 11 are opposed to each other in a non-contact state, that is, with a predetermined gap between the outer peripheral surfaces 11a of the inner magnetic wheels 11, and are linearly directed toward the transport direction F. Are lined up. In other words, the inner magnetic wheels 11 are arranged side by side along the transport direction F in a state where the axial cores that are the axial directions of the inner magnetic wheels 11 are parallel to each other. Further, the inner magnetic wheels 11 are rotated so that the inner magnetic wheels 11 installed in the vicinity of the inner magnetic wheels 11 can be rotated by a magnetic field formed by the inner magnetic wheels 11. A distance between the axes is set by separating the magnetic wheels 11 from each other.
さらに、これら内側磁気車11の外周面11aには、図１および図２に示すように、これら内側磁気車11の周方向に向けて異なる磁性であるＳ極の磁束を形成させるＳ極帯14とＮ極の磁束を形成させるＮ極帯15とが交互に等間隔に螺旋状に形成されている。具体的に、これら内側磁気車11の外周面11aには、これら内側磁気車11の内側面11bに向う一方の軸方向である螺旋方向に向けて時計回りとしての右回りに螺旋状に巻回したＳ極帯14とＮ極帯15とが交互に等しい螺旋ピッチで形成されている。 Further, as shown in FIG. 1 and FIG. 2, an S pole band 14 is formed on the outer peripheral surface 11a of the inner magnetic wheel 11 so as to form an S magnetic flux different in the circumferential direction of the inner magnetic wheel 11. And N-pole bands 15 for forming N-pole magnetic flux are alternately formed in a spiral shape at equal intervals. Specifically, the outer peripheral surface 11a of the inner magnetic wheel 11 is spirally wound clockwise in the clockwise direction toward the spiral direction that is one axial direction toward the inner surface 11b of the inner magnetic wheel 11. The south pole band 14 and the north pole band 15 are alternately formed at the same helical pitch.
このとき、これら内側磁気車11は、これら内側磁気車11それぞれの外周面11aを、これら内側磁気車11の内側面11bに向う一方の軸方向に向けて等間隔に複数個、例えば２個に均等に螺旋状に分割し、これら２個に均等に分割した各領域が互いに磁性の異なるＳ極帯14とＮ極帯15とされている。言い換えると、これら内側磁気車11の外周面11aには、これら内側磁気車11の軸方向に向けてＳ極帯14およびＮ極帯15それぞれであるＳＮ両極帯が交互に等しい螺旋ピッチで形成されている。 At this time, the inner magnetic wheels 11 have a plurality of, for example, two outer peripheral surfaces 11a of the inner magnetic wheels 11 at equal intervals in one axial direction toward the inner surface 11b of the inner magnetic wheels 11. The regions are equally divided into a spiral, and each of the two regions is divided into a south pole zone 14 and a north pole zone 15 having different magnetic properties. In other words, on the outer peripheral surface 11a of these inner magnetic wheels 11, the SN bipolar zones, which are the S pole zone 14 and the N pole zone 15, respectively, are formed at equal helical pitches in the axial direction of the inner magnetic wheels 11. ing.
ここで、これら２個に均等に分割したＳ極帯14およびＮ極帯15のそれぞれは、内側磁気車11の内側面11bに向う一方の軸方向に進むに連れて右回りに巻回した螺旋状に分割されて形成されている。したがって、これら内側磁気車11の外周面11aには、Ｓ極帯14とＮ極帯15とが軸方向に沿って交互に等間隔に形成されている。すなわち、これら内側磁気車11の外周面11aには、これら内側磁気車11の軸方向に向けてＳ極帯14とＮ極帯15とが交互に形成されている。このとき、これら内側磁気車11の内側面11bと、この内側面11bの反対側に位置する他端面である外側面11cとのそれぞれには、Ｓ極帯14あるいはＮ極帯15にて構成された磁極が形成されていない。 Here, each of the S pole zone 14 and the N pole zone 15 equally divided into two is a spiral wound clockwise as it advances in one axial direction toward the inner side surface 11b of the inner magnetic wheel 11. It is divided and formed into a shape. Accordingly, on the outer peripheral surface 11a of these inner magnetic wheels 11, S pole bands 14 and N pole bands 15 are alternately formed at equal intervals along the axial direction. That is, on the outer peripheral surface 11a of these inner magnetic wheels 11, S-pole bands 14 and N-pole bands 15 are alternately formed in the axial direction of these inner magnetic wheels 11. At this time, each of the inner side surface 11b of the inner magnetic wheel 11 and the outer side surface 11c, which is the other end surface located on the opposite side of the inner side surface 11b, is constituted by the S pole zone 14 or the N pole zone 15. Magnetic poles are not formed.
したがって、これら内側磁気車11は、これら内側磁気車11のいずれか一の内側磁気車11である第２磁気車12の外周面11aと、この第２磁気車12に近接されたいずれか他の内側磁気車11である第４磁気車13の外周面11aとのそれぞれを平行に対向させた状態で、搬送方向Ｆに向けて並設されている。さらに、これら内側磁気車11は、第２磁気車12の外周面11aに形成されているＳ極帯14およびＮ極帯15と、第４磁気車13の外周面11aに形成されているＳ極帯14およびＮ極帯15との間の磁気的な引力あるいは反発力である磁力Ｐ１によって、この第２磁気車12の回転に伴って第４磁気車13を回転させる。 Accordingly, the inner magnetic wheel 11 includes the outer peripheral surface 11a of the second magnetic wheel 12 which is any one of the inner magnetic wheels 11 and any other magnetic wheel 11 which is close to the second magnetic wheel 12. The first magnetic wheel 13 that is the inner magnetic wheel 11 and the outer peripheral surface 11a of the fourth magnetic wheel 13 face each other in parallel, and are arranged in parallel in the transport direction F. Further, these inner magnetic wheels 11 include an S pole zone 14 and an N pole zone 15 formed on the outer peripheral surface 11a of the second magnetic wheel 12, and an S pole formed on the outer peripheral surface 11a of the fourth magnetic wheel 13. The fourth magnetic wheel 13 is rotated with the rotation of the second magnetic wheel 12 by the magnetic force P 1 which is a magnetic attractive force or repulsive force between the belt 14 and the N pole belt 15.
よって、これら内側磁気車11は、これら内側磁気車11同士の連動した搬送方向Ｆへの回転によって、これら内側磁気車11が取り付けられている搬送ローラ２のそれぞれを同一の方向である搬送方向Ｆに向けて回転させる。このとき、これら内側磁気車11の外周面11aに形成されているＳ極帯14およびＮ極帯15のそれぞれを、これら内側磁気車11の内側面11bに向う方向である一方の軸方向に向けて右回りに巻回した螺旋状に形成させたことにより、これら内側磁気車11同士の連動した搬送方向Ｆへの回転によって、図１および図２に示すように、これら内側磁気車11それぞれに、これら内側磁気車11を外側面11c側に向けて移動させる軸力ｆ１が生じる。 Therefore, these inner magnetic wheels 11 are rotated in the conveying direction F in which the inner magnetic wheels 11 are linked to each other, so that the conveying rollers 2 to which the inner magnetic wheels 11 are attached are in the same direction. Rotate toward At this time, each of the S pole band 14 and the N pole band 15 formed on the outer peripheral surface 11a of the inner magnetic wheel 11 is directed to one axial direction that is a direction toward the inner side surface 11b of the inner magnetic wheel 11. As shown in FIG. 1 and FIG. 2, each of the inner magnetic wheels 11 is caused to rotate by rotating the inner magnetic wheels 11 in the transporting direction F. An axial force f 1 is generated that moves the inner magnetic wheel 11 toward the outer surface 11c.
さらに、これら内側磁気車11の外側面11cに対向した位置には、短軸状の外側磁気車21が取り付けられている。これら外側磁気車21は、第１の磁性体としての第１磁気車22と第３の磁性体としての第３磁気車23として機能する。具体的に、これら外側磁気車21のそれぞれは、各内側磁気車11に挿通されている軸体７に挿通された状態で、この軸体７に固定されている。すなわち、これら外側磁気車21それぞれは、軸体７の中心軸を回転中心として取り付けられて固定されている。よって、これら外側磁気車21は、軸体７を介して内側磁気車11の同軸に固定され、この内側磁気車11の同心状に周方向に回転可能に同一軸芯として取り付けられている。 Further, a short-axis outer magnetic wheel 21 is attached at a position facing the outer surface 11c of the inner magnetic wheel 11. These outer magnetic wheels 21 function as a first magnetic wheel 22 as a first magnetic body and a third magnetic wheel 23 as a third magnetic body. Specifically, each of the outer magnetic wheels 21 is fixed to the shaft body 7 while being inserted into the shaft bodies 7 inserted into the inner magnetic wheels 11. That is, each of the outer magnetic wheels 21 is attached and fixed with the central axis of the shaft body 7 as the rotation center. Therefore, these outer magnetic wheels 21 are fixed coaxially with the inner magnetic wheel 11 via the shaft body 7, and are attached as the same axis core so as to be rotatable in the circumferential direction concentrically with the inner magnetic wheel 11.
また、これら外側磁気車21は、内側磁気車11の外側面11cに対して所定の間隔を介した状態で取り付けられている。さらに、これら外側磁気車21は、これら外側磁気車21の軸方向に沿った一端面である内側面21bを内側磁気車11の外側面11cに同心状に向かい合わせて対向されて近接されている。言い換えると、これら外側磁気車21は、これら外側磁気車21の内側面21bを、これら外側磁気車21が取り付けられている軸体７に挿通された内側磁気車11の外側面11cに対して非接触な状態で、この軸体７に回転可能に軸支されている。 The outer magnetic wheels 21 are attached to the outer surface 11c of the inner magnetic wheel 11 with a predetermined distance therebetween. Further, these outer magnetic wheels 21 are close to each other so that the inner surface 21b, which is one end surface along the axial direction of these outer magnetic wheels 21, faces the outer surface 11c of the inner magnetic wheel 11 concentrically. . In other words, the outer magnetic wheels 21 are configured such that the inner side surfaces 21b of the outer magnetic wheels 21 are not in contact with the outer surface 11c of the inner magnetic wheel 11 inserted through the shaft body 7 to which the outer magnetic wheels 21 are attached. The shaft body 7 is rotatably supported in a contact state.
ここで、これら外側磁気車21は、内側磁気車11と同一形状であるとともに、この内側磁気車11の外周面11aに形成されている磁極とは正反対の磁極が外周面21aに形成された円筒状の永久磁石である。すなわち、これら外側磁気車21は、内側磁気車11に等しい大きさの円筒状に形成されている。言い換えると、これら外側磁気車21は、各搬送ローラ２および内側磁気車11それぞれの外径寸法に等しい外径寸法を有する円筒状に形成されている。 Here, the outer magnetic wheel 21 has the same shape as the inner magnetic wheel 11, and a cylinder in which a magnetic pole diametrically opposite to the magnetic pole formed on the outer peripheral surface 11a of the inner magnetic wheel 11 is formed on the outer peripheral surface 21a. Shaped permanent magnet. That is, these outer magnetic wheels 21 are formed in a cylindrical shape having the same size as the inner magnetic wheel 11. In other words, these outer magnetic wheels 21 are formed in a cylindrical shape having outer diameter dimensions equal to the outer diameter dimensions of the respective transport rollers 2 and inner magnetic wheels 11.
さらに、これら外側磁気車21は、これら外側磁気車21の周方向に向けてＳ極帯14とＮ極帯15とが交互に等間隔に螺旋状に形成された外周面21aを有している。具体的に、これら外側磁気車21の外周面21aには、これら外側磁気車21の内側面21bに向う軸方向に向けて反時計回りとしての左回りに螺旋状に巻回したＳ極帯14とＮ極帯15とが交互に等しい螺旋ピッチで形成されている。 Further, these outer magnetic wheels 21 have outer peripheral surfaces 21a in which S-pole bands 14 and N-pole bands 15 are alternately spirally formed in the circumferential direction of these outer magnetic wheels 21. . Specifically, on the outer peripheral surface 21a of these outer magnetic wheels 21, a south pole band 14 spirally wound counterclockwise in the axial direction toward the inner surface 21b of these outer magnetic wheels 21 is provided. And N pole bands 15 are alternately formed with the same helical pitch.
すなわち、これら外側磁気車21の外周面21aには、これら外側磁気車21の外側面21cに向う他方の軸方向である螺旋方向に向けて時計回りとしての右回りに螺旋状に巻回したＳ極帯14とＮ極帯15とが交互に等しい螺旋ピッチで形成されている。さらに、これら外側磁気車21の外周面21aに形成されているＳ極帯14およびＮ極帯15と、各内側磁気車11の外周面11aに形成されているＳ極帯14およびＮ極帯15とは、等しい角度で傾斜した螺旋状に形成されているとともに、これらＳ極帯14およびＮ極帯15のそれぞれが等しい幅寸法を有している。 That is, the outer circumferential surfaces 21a of the outer magnetic wheels 21 are spirally wound clockwise in the clockwise direction toward the spiral direction that is the other axial direction toward the outer surface 21c of the outer magnetic wheels 21. Polar zones 14 and N-pole zones 15 are alternately formed at the same helical pitch. Further, the S pole zone 14 and the N pole zone 15 formed on the outer peripheral surface 21 a of the outer magnetic wheel 21, and the S pole zone 14 and the N pole zone 15 formed on the outer peripheral surface 11 a of each inner magnetic wheel 11. Is formed in a spiral shape inclined at an equal angle, and each of the S pole zone 14 and the N pole zone 15 has an equal width dimension.
ここで、これら外側磁気車21の外周面21aには、内側磁気車11の外周面11aに形成されている磁極、すなわちＳ極帯14およびＮ極帯15の間隔である螺旋ピッチに対応した螺旋ピッチで、これらＳ極帯14およびＮ極帯15それぞれが軸方向に向けて交互に等間隔に形成されている。このとき、これら外側磁気車21の内側面21bと、この内側面21bの反対側に位置する外側面21cとには、Ｓ極帯14あるいはＮ極帯15などの磁極が形成されていない。 Here, the outer peripheral surface 21a of the outer magnetic wheel 21 has a spiral corresponding to the magnetic pole formed on the outer peripheral surface 11a of the inner magnetic wheel 11, that is, the spiral pitch that is the interval between the S pole band 14 and the N pole band 15. At the pitch, the S pole band 14 and the N pole band 15 are alternately formed at equal intervals in the axial direction. At this time, magnetic poles such as the S pole zone 14 or the N pole zone 15 are not formed on the inner side surface 21b of the outer magnetic wheel 21 and the outer side surface 21c located on the opposite side of the inner side surface 21b.
また、これら外側磁気車21は、これら外側磁気車21の互いの外周面21aを非接触な状態、すなわち所定の間隙を介した状態で対向させており、搬送方向Ｆに向けて直線状に並べられている。言い換えると、これら外側磁気車21は、これら外側磁気車21の軸方向である軸芯を互いに平行にした状態で、搬送方向Ｆに沿って並設されている。さらに、これら外側磁気車21は、これら外側磁気車21にて形成される磁界によって、これら外側磁気車21に近接して設置されている外側磁気車21を連動させて回転できる程度に、これら外側磁気車21間が離間されて設置されている。 Further, these outer magnetic wheels 21 have their outer peripheral surfaces 21a opposed to each other in a non-contact state, that is, through a predetermined gap, and are arranged in a straight line toward the transport direction F. It has been. In other words, the outer magnetic wheels 21 are arranged side by side along the transport direction F in a state where the axial cores that are the axial directions of the outer magnetic wheels 21 are parallel to each other. Further, the outer magnetic wheels 21 are rotated so that the outer magnetic wheels 21 installed in the vicinity of the outer magnetic wheels 21 can be rotated by a magnetic field formed by the outer magnetic wheels 21. The magnetic wheels 21 are separated from each other.
したがって、これら外側磁気車21は、これら外側磁気車21のいずれか一の外側磁気車21である第１磁気車22の外周面21aと、この第１磁気車22に近接されたいずれか他の外側磁気車21である第３磁気車23の外周面21aとのそれぞれを平行に対向させた状態で、搬送方向Ｆに向けて並設されている。さらに、これら外側磁気車21は、第１磁気車22の外周面21aに形成されているＳ極帯14およびＮ極帯15と、第３磁気車23の外周面21aに形成されているＳ極帯14およびＮ極帯15との間の磁力Ｐ２によって、この第１磁気車22の回転に伴って第３磁気車23を回転させる。 Therefore, these outer magnetic wheels 21 are the outer magnetic surface 21a of the first magnetic wheel 22 which is one of the outer magnetic wheels 21 and any other magnetic wheel 21 close to the first magnetic wheel 22. In the state where the outer peripheral surface 21a of the third magnetic wheel 23 that is the outer magnetic wheel 21 is opposed to each other in parallel, they are arranged in parallel in the transport direction F. Further, the outer magnetic wheel 21 includes an S pole zone 14 and an N pole zone 15 formed on the outer peripheral surface 21a of the first magnetic wheel 22, and an S pole formed on the outer peripheral surface 21a of the third magnetic wheel 23. The third magnetic wheel 23 is rotated by the rotation of the first magnetic wheel 22 by the magnetic force P 2 between the band 14 and the N pole band 15.
よって、これら外側磁気車21は、これら外側磁気車21同士の連動した搬送方向Ｆへの回転によって、これら外側磁気車21が取り付けられている搬送ローラ２のそれぞれを同一の方向である搬送方向Ｆに向けて回転させる。このとき、これら外側磁気車21の外周面21aに形成されているＳ極帯14およびＮ極帯15のそれぞれを、これら外側磁気車21の外側面21cに向う方向である他方の軸方向に向けて右回りに巻回した螺旋状に形成させたことにより、これら外側磁気車21同士の連動した搬送方向Ｆへの回転によって、図１および図２に示すように、これら外側磁気車21それぞれに、これら外側磁気車21を内側面21b側に向けて移動させる軸力ｆ２が生じる。 Therefore, these outer magnetic wheels 21 are rotated in the conveying direction F in which these outer magnetic wheels 21 are linked to each other so that the conveying rollers 2 to which the outer magnetic wheels 21 are attached are in the same direction. Rotate toward At this time, each of the S pole band 14 and the N pole band 15 formed on the outer peripheral surface 21a of the outer magnetic wheel 21 is directed to the other axial direction, which is the direction toward the outer surface 21c of the outer magnetic wheel 21. As shown in FIG. 1 and FIG. 2, each outer magnetic wheel 21 is caused to rotate by rotating the outer magnetic wheels 21 in the conveying direction F. , the axial force f 2 that moves towards these outer magnetic wheel 21 on the inner surface 21b side occurs.
このとき、これら外側磁気車21は、これら外側磁気車21の外周面21a間に作用する磁力が、内側磁気車11の外周面11a間に作用する磁力と等しくなるように、これら外側磁気車21の外周面21a間の離間距離が設置されている。言い換えると、これら外側磁気車21は、これら外側磁気車21の外周面21a間の距離が、内側磁気車11の外周面11a間の距離と等しくされている。したがって、これら外側磁気車21は、これら外側磁気車21および内側磁気車11のそれぞれを連動させた際に生じる、各外側磁気車21の内側面21b側に向かう力と、各内側磁気車11の外側面11c側に向う力とが等しくなるように構成されている。 At this time, the outer magnetic wheels 21 are arranged so that the magnetic force acting between the outer peripheral surfaces 21a of the outer magnetic wheels 21 is equal to the magnetic force acting between the outer peripheral surfaces 11a of the inner magnetic wheels 11. The distance between the outer peripheral surfaces 21a is set. In other words, in these outer magnetic wheels 21, the distance between the outer peripheral surfaces 21a of these outer magnetic wheels 21 is equal to the distance between the outer peripheral surfaces 11a of the inner magnetic wheels 11. Therefore, these outer magnetic wheels 21 are generated when the outer magnetic wheels 21 and the inner magnetic wheels 11 are interlocked with each other, and the forces toward the inner side surfaces 21b of the outer magnetic wheels 21 and the inner magnetic wheels 11 The force directed toward the outer side surface 11c is configured to be equal.
そして、複数の搬送ローラ２にて構成された搬送面４の最も搬送下流側に位置する内側磁気車11および外側磁気車21には、これら内側磁気車11および外側磁気車21を周方向に向けて連動させて回転駆動させる駆動手段としての駆動モータ31が軸体７を介して取り付けられている。この駆動モータ31は、搬送方向Ｆに沿った一端部である搬送下流側に設けられている。さらに、この駆動モータ31は、搬送面４の搬送下流側よりも、この搬送面４の搬送方向Ｆに沿った外側に取り付けられている。 The inner magnetic wheel 11 and the outer magnetic wheel 21 that are located on the most downstream side of the conveying surface 4 constituted by the plurality of conveying rollers 2 are directed to the inner magnetic wheel 11 and the outer magnetic wheel 21 in the circumferential direction. A drive motor 31 is attached via a shaft body 7 as a drive means for rotationally driving in conjunction with each other. The drive motor 31 is provided on the downstream side of conveyance, which is one end along the conveyance direction F. Further, the drive motor 31 is attached to the outer side of the transport surface 4 along the transport direction F from the transport downstream side of the transport surface 4.
すなわち、この駆動モータ31は、この駆動モータ31に取り付けられた内側磁気車11および外側磁気車21を連動させて回転駆動させることにより、これら内側磁気車11の外周面11a間に作用する磁力Ｐ１と、これら外側磁気車21の外周面21a間に作用する磁力Ｐ２とによって、これら内側磁気車11および外側磁気車21のそれぞれを同一方向である搬送方向Ｆに向けて回転駆動させる。したがって、この駆動モータ31は、これら内側磁気車11および外側磁気車21の連動した搬送方向Ｆへの回転によって、これら内側磁気車11および外側磁気車21を軸方向に沿って移動させようとする軸力ｆ１,ｆ２を打ち消しつつ、これら内側磁気車11および外側磁気車21が取り付けられている各搬送ローラ２のそれぞれを同一方向である搬送方向Ｆに回転駆動させる。 That is, the drive motor 31 rotates and drives the inner magnetic wheel 11 and the outer magnetic wheel 21 attached to the drive motor 31 so as to act between the outer peripheral surfaces 11a of the inner magnetic wheel 11. 1 and the magnetic force P 2 acting between the outer peripheral surfaces 21a of the outer magnetic wheels 21 cause the inner magnetic wheel 11 and the outer magnetic wheel 21 to be driven to rotate in the transport direction F, which is the same direction. Therefore, the drive motor 31 tries to move the inner magnetic wheel 11 and the outer magnetic wheel 21 along the axial direction by the rotation of the inner magnetic wheel 11 and the outer magnetic wheel 21 in the interlocked conveyance direction F. While canceling the axial forces f 1 and f 2 , the respective conveying rollers 2 to which the inner magnetic wheel 11 and the outer magnetic wheel 21 are attached are rotated in the conveying direction F, which is the same direction.
次に、上記一実施の形態の動作である駆動伝達方法について説明する。 Next, the drive transmission method which is the operation of the above embodiment will be described.
まず、駆動モータ31を駆動させて、図２に示すように、最も搬送下流側に位置する内側磁気車11と外側磁気車21とを連動させて搬送方向Ｆ側である正方向としての側面視右回りCWに回転させる。 First, the drive motor 31 is driven, and as shown in FIG. 2, the inner magnetic wheel 11 and the outer magnetic wheel 21 that are located on the most downstream side of the conveyance are interlocked to each other as viewed from the side as the forward direction that is the conveyance direction F side. Rotate clockwise CW.
このとき、この駆動モータ31にて回転駆動される内側磁気車11としての第２磁気車12の外周面11aに形成されているＳ極帯14あるいはＮ極帯15と、この第２磁気車12の搬送上流側に位置する内側磁気車11としての第４磁気車13の外周面11aに形成されているＮ極帯15あるいはＳ極帯14との間の磁力Ｐ１によって、これら第２磁気車12と第４磁気車13との互いに異なるＳ極帯14とＮ極帯15とが最も近接した状態で磁気的に引き合い、この磁気的に引き合う状態を維持しようとする。 At this time, the S pole band 14 or the N pole band 15 formed on the outer peripheral surface 11a of the second magnetic wheel 12 as the inner magnetic wheel 11 rotated by the drive motor 31, and the second magnetic wheel 12 These second magnetic wheels are generated by the magnetic force P 1 between the N pole zone 15 and the S pole zone 14 formed on the outer peripheral surface 11a of the fourth magnetic wheel 13 as the inner magnetic wheel 11 positioned on the upstream side of the transfer. The different S-pole band 14 and N-pole band 15 of 12 and the fourth magnetic wheel 13 are magnetically attracted in the closest state, and this magnetically attracted state is to be maintained.
したがって、この第２磁気車12の側面視右回りCWの回転に伴って、この第２磁気車12を追うように第４磁気車13が同一方向である側面視右回りCWに回転する。 Accordingly, with the rotation of the second magnetic wheel 12 in the side view clockwise CW, the fourth magnetic wheel 13 rotates in the same direction in the side view clockwise CW so as to follow the second magnetic wheel 12.
さらに、これら第２磁気車12および第４磁気車13それぞれの外周面11aに形成したＳ極帯14およびＮ極帯15のそれぞれが、これら第２磁気車12および第４磁気車13の内側面11b側に向けて右回りに巻回した螺旋状である。 Furthermore, each of the S pole zone 14 and the N pole zone 15 formed on the outer peripheral surface 11a of the second magnetic wheel 12 and the fourth magnetic wheel 13 is the inner surface of the second magnetic wheel 12 and the fourth magnetic wheel 13, respectively. It is a spiral shape wound clockwise toward the 11b side.
このため、この第２磁気車12の側面視右回りCWへの回転によって、この第２磁気車12の外周面11aに形成されている螺旋状のＳ極帯14およびＮ極帯15のそれぞれが、この第２磁気車12の外側面11c側に向けて移動する。 For this reason, each of the spiral S-pole band 14 and N-pole band 15 formed on the outer peripheral surface 11a of the second magnetic wheel 12 by rotation of the second magnetic wheel 12 in the clockwise direction CW when viewed from the side is The second magnetic wheel 12 moves toward the outer surface 11c side.
この結果、この第２磁気車12の外周面11aに形成されている螺旋状のＳ極帯14およびＮ極帯15を、第４磁気車13の外周面11aに形成されている螺旋状のＮ極帯15およびＳ極帯14が追うように、この第４磁気車13が第２磁気車12を追従して回転する。 As a result, the spiral S-pole band 14 and N-pole band 15 formed on the outer peripheral surface 11a of the second magnetic wheel 12 are replaced with the spiral N pole formed on the outer peripheral surface 11a of the fourth magnetic wheel 13. The fourth magnetic wheel 13 rotates following the second magnetic wheel 12 so that the polar zone 15 and the south pole zone 14 follow.
よって、図１および図２に示すように、これら第２磁気車12および第４磁気車13のそれぞれに、これら第２磁気車12および第４磁気車13の軸方向に沿って、これら第２磁気車12および第４磁気車13それぞれの外側面11c側に向う軸力ｆ１が作用する。 Therefore, as shown in FIGS. 1 and 2, the second magnetic wheel 12 and the fourth magnetic wheel 13 are respectively connected to the second magnetic wheel 12 and the fourth magnetic wheel 13 along the axial direction of the second magnetic wheel 12 and the fourth magnetic wheel 13. An axial force f 1 directed toward the outer surface 11c of each of the magnetic wheel 12 and the fourth magnetic wheel 13 acts.
一方、駆動モータ31にて回転駆動される外側磁気車21としての第１磁気車22の外周面21aに形成されているＳ極帯14あるいはＮ極帯15と、この第１磁気車22の搬送上流側に位置する外側磁気車21としての第３磁気車23の外周面21aに形成されているＮ極帯15あるいはＳ極帯14との間の磁力Ｐ２によって、これら第１磁気車22と第３磁気車23との互いに異なるＳ極帯14とＮ極帯15とが最も近接した状態で磁気的に引き合い、この磁気的に引き合う状態を維持しようとする。 On the other hand, the S pole zone 14 or the N pole zone 15 formed on the outer peripheral surface 21a of the first magnetic wheel 22 as the outer magnetic wheel 21 driven to rotate by the drive motor 31, and the conveyance of the first magnetic wheel 22 by the magnetic force P 2 between the N Kyokutai 15 or S Kyokutai 14 formed on the outer circumferential surface 21a of the third magnetic wheel 23 as an outer magnetic wheel 21 located on the upstream side, these first magnetic wheel 22 The S magnetic pole zone 14 and the N magnetic pole zone 15 which are different from each other with the third magnetic wheel 23 are magnetically attracted to each other and try to maintain this magnetically attractive state.
したがって、この第１磁気車22の側面視右回りCWの回転に伴って、この第１磁気車22を追うように第３磁気車23が側面視右回りCWに回転する。 Accordingly, with the rotation of the first magnetic wheel 22 in the clockwise direction CW in the side view, the third magnetic wheel 23 rotates in the clockwise direction CW in the side view so as to follow the first magnetic wheel 22.
さらに、これら第１磁気車22および第３磁気車23それぞれの外周面21aに形成したＳ極帯14およびＮ極帯15のそれぞれが、これら第１磁気車22および第３磁気車23の内側面21b側に向けて左回りに巻回した螺旋状である。 Further, each of the S pole zone 14 and the N pole zone 15 formed on the outer peripheral surface 21a of each of the first magnetic wheel 22 and the third magnetic wheel 23 is the inner surface of the first magnetic wheel 22 and the third magnetic wheel 23. A spiral wound counterclockwise toward the 21b side.
このため、この第１磁気車22の側面視右回りCWへの回転によって、この第１磁気車22の外周面21aに形成されている螺旋状のＳ極帯14およびＮ極帯15のそれぞれが、この第１磁気車22の内側面21b側に向けて移動する。 For this reason, each of the spiral S-pole band 14 and N-pole band 15 formed on the outer peripheral surface 21a of the first magnetic wheel 22 is rotated by the clockwise rotation of the first magnetic wheel 22 in the clockwise direction CW. The first magnetic wheel 22 moves toward the inner side surface 21b.
この結果、この第１磁気車22の外周面21aに形成されている螺旋状のＳ極帯14およびＮ極帯15を、第３磁気車23の外周面21aに形成されている螺旋状のＮ極帯15およびＳ極帯14が追うように、この第３磁気車23が第１の磁性体22を追従して回転する。 As a result, the spiral S-pole band 14 and N-pole band 15 formed on the outer peripheral surface 21a of the first magnetic wheel 22 are replaced with the spiral N pole formed on the outer peripheral surface 21a of the third magnetic wheel 23. The third magnetic wheel 23 rotates following the first magnetic body 22 so that the polar zone 15 and the south pole zone 14 follow.
よって、図１および図２に示すように、これら第１磁気車22および第３磁気車23のそれぞれに、これら第１磁気車22および第３磁気車23の軸方向に沿って、これら第１磁気車22および第３磁気車23それぞれの内側面21b側に向う軸力ｆ２が作用する。 Therefore, as shown in FIGS. 1 and 2, the first magnetic wheel 22 and the third magnetic wheel 23 are respectively disposed along the axial direction of the first magnetic wheel 22 and the third magnetic wheel 23. axial force f 2 towards the magnetic wheel 22 and the third magnetic wheel 23 inner surface 21b side of the respective acts.
このとき、これら第１磁気車22および第３磁気車23に作用する内側面21b側への軸力ｆ２が、第２磁気車12および第４磁気車13に作用する外側面11c側への軸力ｆ１と等しいことによって、これら第１磁気車22、第２磁気車12、第３磁気車23および第４磁気車13それぞれに作用する軸力ｆ１,ｆ２が互いに打ち消し合う。 In this case, the axial force f 2 to the inner surface 21b side acting on these first magnetic wheel 22 and the third magnetic wheel 23, the outward surface 11c side acting on the second magnetic wheel 12 and the fourth magnetic wheel 13 by equal axial forces f 1, these first magnetic wheel 22, the second magnetic wheel 12, the axial force f 1 acting on each third magnetic wheel 23 and the fourth magnetic wheel 13, f 2 cancel each other.
この結果、これら第１磁気車22、第２磁気車12、第３磁気車23および第４磁気車13のそれぞれを軸方向に移動させることなく、これら第１磁気車22、第２磁気車12、第３磁気車23および第４磁気車13のそれぞれが搬送方向Ｆに沿った側面視右回りCWに連動して回転する。 As a result, the first magnetic wheel 22, the second magnetic wheel 12, the third magnetic wheel 23, and the fourth magnetic wheel 13 are not moved in the axial direction, and the first magnetic wheel 22, the second magnetic wheel 12 are moved. Each of the third magnetic wheel 23 and the fourth magnetic wheel 13 rotates in conjunction with the clockwise CW in side view along the conveyance direction F.
したがって、これら第１磁気車22、第２磁気車12、第３磁気車23および第４磁気車13それぞれの側面視右回りCWの回転に伴って、これら第１磁気車22、第２磁気車12、第３磁気車23および第４磁気車13が取り付けられている搬送ローラ２のそれぞれが側面視右回りCWに回転する。 Accordingly, as the first magnetic wheel 22, the second magnetic wheel 12, the third magnetic wheel 23, and the fourth magnetic wheel 13 rotate in the clockwise direction CW, the first magnetic wheel 22 and the second magnetic wheel respectively. 12, Each of the conveyance rollers 2 to which the third magnetic wheel 23 and the fourth magnetic wheel 13 are attached rotates clockwise CW as viewed from the side.
このため、これら搬送ローラ２それぞれの側面視右回りCWへの回転によって、これら搬送ローラ２上の搬送面４へと搬送された搬送物が、これら搬送ローラ２の回転によって搬送上流側から搬送下流側へと搬送方向Ｆに沿って搬送される。 For this reason, the conveyed product conveyed to the conveying surface 4 on the conveying roller 2 by the rotation of the conveying rollers 2 in the clockwise direction CW in the side view is conveyed from the conveying upstream side to the conveying downstream by the rotation of the conveying rollers 2. It is conveyed along the conveyance direction F to the side.
上述したように、上記一実施の形態によれば、搬送ローラ２に固定されている軸体７に固定された内側磁気車11の外周面11aに螺旋状に形成したＳ極帯14およびＮ極帯15と、この内側磁気車11と同じ軸体７に取り付けられた外側磁気車21の外周面21aに螺旋状に形成したＳ極帯14およびＮ極帯15とを正反対に構成した。この結果、これら内側磁気車11および外側磁気車21のそれぞれを連動させて回転させた際に生じる、これら内側磁気車11に作用する軸力ｆ１と、これら外側磁気車21に作用する軸力ｆ２とが正反対の力となる。このため、これら内側磁気車11および外側磁気車21を連動させた際に生じる、これら内側磁気車11に作用する軸力ｆ１を、これら外側磁気車21に作用する軸力ｆ２で吸収できる。 As described above, according to the above-described embodiment, the S pole band 14 and the N pole formed spirally on the outer peripheral surface 11a of the inner magnetic wheel 11 fixed to the shaft body 7 fixed to the transport roller 2. The band 15 and the S pole band 14 and the N pole band 15 formed in a spiral shape on the outer peripheral surface 21a of the outer magnetic wheel 21 attached to the same shaft body 7 as the inner magnetic wheel 11 are configured to be opposite to each other. As a result, the axial force f 1 acting on the inner magnetic wheel 11 and the axial force acting on the outer magnetic wheel 21 generated when the inner magnetic wheel 11 and the outer magnetic wheel 21 are rotated in conjunction with each other. and f 2 is the opposite of power. Therefore, the axial force f 1 acting on the inner magnetic wheel 11 generated when the inner magnetic wheel 11 and the outer magnetic wheel 21 are interlocked can be absorbed by the axial force f 2 acting on the outer magnetic wheel 21. .
さらに、これら内側磁気車11および外側磁気車21のそれぞれを等しい大きさの円筒状とし、これら内側磁気車11および外側磁気車21の外周面11a,21aに形成されているＳ極帯14とＮ極帯15の螺旋ピッチを等しくして、これら内側磁気車11の外周面11a間に作用する磁力Ｐ１と、これら外側磁気車21の外周面21a間に作用する磁力Ｐ２とを等しくした。この結果、これら内側磁気車11および外側磁気車21のそれぞれを連動させて回転させた際に生じる、これら内側磁気車11に作用する軸力ｆ１の大きさと、これら外側磁気車21に作用する軸力ｆ２の大きさとが等しくなる。 Further, each of the inner magnetic wheel 11 and the outer magnetic wheel 21 is formed into a cylindrical shape having the same size, and the S pole bands 14 and N formed on the outer peripheral surfaces 11a and 21a of the inner magnetic wheel 11 and the outer magnetic wheel 21 are formed. The magnetic pitch P 1 acting between the outer peripheral surfaces 11 a of the inner magnetic wheels 11 and the magnetic force P 2 acting between the outer peripheral surfaces 21 a of the outer magnetic wheels 21 are made equal by making the spiral pitches of the pole bands 15 equal. As a result, the magnitude of the axial force f 1 acting on the inner magnetic wheel 11 and the outer magnetic wheel 21 that are generated when the inner magnetic wheel 11 and the outer magnetic wheel 21 are rotated in conjunction with each other. the magnitude of the axial force f 2 and are equal.
したがって、これら内側磁気車11および外側磁気車21を連動させた際に生じる、これら内側磁気車11に作用する軸力ｆ１と、これら外側磁気車21に作用する軸力ｆ２とを打ち消し合うことができる。このため、これら内側磁気車11および外側磁気車21のそれぞれを連動させて同じ方向である搬送方向Ｆに回転させた際に、これら内側磁気車11および外側磁気車21が軸方向に向けて移動しなくなる。この結果、これら内側磁気車11および外側磁気車21のそれぞれが軸方向に沿って移動しないようにコンベヤフレーム５,６に強固に固定させる必要が無くなる。よって、これら内側磁気車11および外側磁気車21が取り付けられている軸体７を回転可能に軸支する構成を簡略化できるから、これら軸体７を軸支するコンベヤフレーム５,６の構成を簡略化できる。 Therefore, the axial force f 1 acting on the inner magnetic wheel 11 and the axial force f 2 acting on the outer magnetic wheel 21 generated when the inner magnetic wheel 11 and the outer magnetic wheel 21 are interlocked cancel each other. be able to. Therefore, when the inner magnetic wheel 11 and the outer magnetic wheel 21 are interlocked and rotated in the transport direction F, which is the same direction, the inner magnetic wheel 11 and the outer magnetic wheel 21 move in the axial direction. No longer. As a result, it is not necessary to firmly fix the inner magnetic wheel 11 and the outer magnetic wheel 21 to the conveyor frames 5 and 6 so as not to move in the axial direction. Therefore, since the structure which rotatably supports the shaft body 7 to which the inner magnetic wheel 11 and the outer magnetic wheel 21 are attached can be simplified, the structure of the conveyor frames 5 and 6 which support the shaft body 7 can be simplified. It can be simplified.
また、外周面11aにＳ極帯14およびＮ極帯15とが同様に構成された複数の内側磁気車11の外周面11a同士を非接触な状態で、平行に対向させて回転可能に軸支させた。この結果、これら内側磁気車11の外周面11a同士が線状に対向するから、これら内側磁気車11の外周面11a同士が磁気的に引き合っている際に、これら内側磁気車11の外周面11a間に軸方向に沿った反発磁力が生じなくなる。したがって、いずれか一の内側磁気車11の外周面11aに形成される磁界を、この内側磁気車11に隣接されたいずれか他の内側磁気車11の外周面11aの軸方向に沿った全体に効率良く届かせることができる。 Further, the outer peripheral surfaces 11a of the plurality of inner magnetic wheels 11 in which the S pole zone 14 and the N pole zone 15 are similarly configured on the outer peripheral surface 11a are rotatably supported while facing each other in a non-contact state. I let you. As a result, since the outer peripheral surfaces 11a of these inner magnetic wheels 11 are linearly opposed to each other, when the outer peripheral surfaces 11a of these inner magnetic wheels 11 are magnetically attracted to each other, the outer peripheral surfaces 11a of these inner magnetic wheels 11 are No repulsive magnetic force is generated along the axial direction. Therefore, the magnetic field formed on the outer peripheral surface 11a of any one of the inner magnetic wheels 11 is applied to the whole along the axial direction of the outer peripheral surface 11a of any other inner magnetic wheel 11 adjacent to the inner magnetic wheel 11. It can be delivered efficiently.
このため、これら内側磁気車11の外周面11a間に作用する磁力Ｐ１が、これら内側磁気車11の外周面11a間の軸方向に沿った全体に亘って作用する。したがって、これら内側磁気車11の外周面11a間の磁力Ｐ１がより効率良く作用するから、これら内側磁気車11の外周面11a間に生じる磁力Ｐ１をより大きくできる。よって、これら内側磁気車11の外周面11aの互いに異なるＳ極帯14およびＮ極帯15間が最も接近して引き合う状態を常に維持しようとする磁力Ｐ１を最大限に利用できる。このため、これら内側磁気車11間の磁力Ｐ１の損失を最小限にできるから、これら内側磁気車11の回転を効率良く伝達できる。したがって、これら内側磁気車11をより確実に連動させて回転できるので、これら内側磁気車11が取り付けられている搬送ローラ２それぞれを効率良く回転駆動できる。 For this reason, the magnetic force P 1 acting between the outer peripheral surfaces 11 a of these inner magnetic wheels 11 acts on the whole along the axial direction between the outer peripheral surfaces 11 a of these inner magnetic wheels 11. Therefore, the magnetic force P 1 between the outer peripheral surfaces 11a of the inner magnetic wheels 11 acts more efficiently, and therefore the magnetic force P 1 generated between the outer peripheral surfaces 11a of the inner magnetic wheels 11 can be further increased. Therefore, it is possible to make maximum use of the magnetic force P 1 that always maintains the state in which the different S pole bands 14 and N pole bands 15 of the outer peripheral surface 11a of the inner magnetic wheel 11 are most closely attracted to each other. Thus, since the loss of the magnetic force P 1 between these inner magnetic wheel 11 can be minimized, it can efficiently transmit the rotation of the inner magnetic wheel 11. Therefore, since these inner magnetic wheels 11 can be rotated in a more reliable manner, each of the transport rollers 2 to which these inner magnetic wheels 11 are attached can be efficiently rotated.
このとき、これら内側磁気車11の外周面11aに形成されている螺旋状のＳ極帯14およびＮ極帯15と正反対の磁極を複数の外側磁気車21それぞれの外周面21aに形成し、これら複数の外側磁気車21の外周面21a同士を非接触な状態で、平行に対向させて回転可能に軸支させた。この結果、これら外側磁気車21それぞれも、上述した内側磁気車11と同様の作用効果を奏することができる。 At this time, the magnetic poles opposite to the spiral S-pole band 14 and N-pole band 15 formed on the outer peripheral surface 11a of the inner magnetic wheel 11 are formed on the outer peripheral surfaces 21a of the plurality of outer magnetic wheels 21, respectively. The outer peripheral surfaces 21a of the plurality of outer magnetic wheels 21 are pivotally supported so as to face each other in parallel without being in contact with each other. As a result, each of these outer magnetic wheels 21 can also exhibit the same effects as the above-described inner magnetic wheel 11.
さらに、最も搬送下流側に位置する内側磁気車11および外側磁気車21それぞれを駆動モータ31にて搬送方向側である側面視右回りCWに回転駆動させる。すると、これら内側磁気車11間および外側磁気車21間の磁力Ｐ１,Ｐ２によって、これら内側磁気車11および外側磁気車21のそれぞれが同じ方向である搬送方向Ｆに沿った側面視右回りCWに回転する。したがって、駆動モータ31にて内側磁気車11および外側磁気車21のいずれか一つを回転させるだけで、これら内側磁気車11および外側磁気車21のそれぞれを連動させて搬送方向Ｆに沿った側面視右回りCWに回転できる。 Further, each of the inner magnetic wheel 11 and the outer magnetic wheel 21 positioned on the most downstream side of the conveyance is rotationally driven by the drive motor 31 in the clockwise direction CW as viewed from the side, which is the conveyance direction side. Then, due to the magnetic forces P 1 and P 2 between the inner magnetic wheels 11 and the outer magnetic wheels 21, the inner magnetic wheels 11 and the outer magnetic wheels 21 are clockwise in a side view along the conveyance direction F, which is the same direction. Rotate to CW. Therefore, only one of the inner magnetic wheel 11 and the outer magnetic wheel 21 is rotated by the drive motor 31, and the side surfaces along the transport direction F are interlocked with each other. Can rotate clockwise CW.
このため、これら内側磁気車11および外側磁気車21の連動した回転に伴って、これら内側磁気車11および外側磁気車21が取り付けられている複数の搬送ローラ２のそれぞれを搬送方向Ｆに回転できる。よって、これら搬送ローラ２のそれぞれを駆動モータ31などにて回転駆動させる構成に比べ、これら搬送ローラ２の回転にて搬送物を搬送させる構造を簡単にできるとともに薄型化できる。したがって、ローラコンベヤ１の構成を簡単にでき、より小型化できる。 Therefore, each of the plurality of transport rollers 2 to which the inner magnetic wheel 11 and the outer magnetic wheel 21 are attached can be rotated in the transport direction F along with the interlocking rotation of the inner magnetic wheel 11 and the outer magnetic wheel 21. . Therefore, as compared with the configuration in which each of the transport rollers 2 is rotationally driven by the drive motor 31 or the like, the structure for transporting the transported object by the rotation of the transport rollers 2 can be simplified and thinned. Therefore, the configuration of the roller conveyor 1 can be simplified and the size can be further reduced.
また、駆動モータ31による内側磁気車11および外側磁気車21の回転駆動を、これら内側磁気車11および外側磁気車21それぞれによる磁力Ｐ１,Ｐ２を利用して、これら内側磁気車11および外側磁気車21のそれぞれを搬送方向Ｆに回転させて、各搬送ローラ２を搬送方向Ｆに回転駆動させる構成とした。この結果、ローラコンベヤ１の機械的な摩擦や発塵、衝撃や大トルクなどによる破損が少なく、多軸駆動を支障なくできる。さらに、このローラコンベヤ１の構成が簡略化されて、騒音を小さくでき、高速化を図ることができるとともに、このローラコンベヤ１のトラブルの発生を減少できる。 Further, the rotation of the inner magnetic wheel 11 and the outer magnetic wheel 21 by the drive motor 31 is used to utilize the magnetic forces P 1 and P 2 of the inner magnetic wheel 11 and the outer magnetic wheel 21, respectively. Each of the magnetic wheels 21 is rotated in the transport direction F, and each transport roller 2 is rotationally driven in the transport direction F. As a result, the roller conveyor 1 is hardly damaged due to mechanical friction, dust generation, impact, large torque, etc., and multi-axis driving can be performed without any problem. Furthermore, the configuration of the roller conveyor 1 is simplified, noise can be reduced, the speed can be increased, and the occurrence of troubles in the roller conveyor 1 can be reduced.
さらに、駆動モータ31による内側磁気車11および外側磁気車21の連動させた回転によって、これら内側磁気車11および外側磁気車21が取り付けられている各搬送ローラ２を回転駆動させる構成とした。この結果、これら搬送ローラ２に巻回させて、これら搬送ローラ２を連動させて回転駆動させるチェーンやベルトなどの機構を無くすことができる。このため、コンベヤ本体３の下面に突出するチェーンやベルトなどの突出物を無くすことができるから、コンベヤ本体３の構成をより簡略化できる。 In addition, the transport roller 2 to which the inner magnetic wheel 11 and the outer magnetic wheel 21 are attached is driven to rotate by the interlocking rotation of the inner magnetic wheel 11 and the outer magnetic wheel 21 by the drive motor 31. As a result, it is possible to eliminate a mechanism such as a chain or a belt that is wound around the transport rollers 2 and is driven to rotate in conjunction with the transport rollers 2. For this reason, since protrusions, such as a chain and a belt which protrude on the lower surface of the conveyor body 3, can be eliminated, the configuration of the conveyor body 3 can be further simplified.
なお、上記一実施の形態では、内側磁気車11および外側磁気車21のそれぞれを一体的に構成された一体型の永久磁石としたが、これら内側磁気車11および外側磁気車21のそれぞれを、複数の永久磁石を組み合わせて構成することもできる。
また、ローラコンベヤ１の各搬送ローラ２の最も搬送下流側に駆動モータ31を取り付けたが、この駆動モータ31を各搬送ローラ２の搬送上流側や中央部などに取り付けて、これら搬送ローラ２のそれぞれを連動させることもできる。
In the above-described embodiment, each of the inner magnetic wheel 11 and the outer magnetic wheel 21 is formed as an integrated permanent magnet, but each of the inner magnetic wheel 11 and the outer magnetic wheel 21 is A plurality of permanent magnets may be combined .
In addition, the drive motor 31 is attached to the most downstream side of each conveyance roller 2 of the roller conveyor 1, but this drive motor 31 is attached to the conveyance upstream side of each conveyance roller 2, the central portion, etc. Each can be linked.
さらに、図２に示すように、内側磁気車11のＮ極帯15と、外側磁気車21のＮ極帯15とを向い合わせた状態で、これら内側磁気車11および外側磁気者21のそれぞれを同一の軸体７に軸止めさせたが、これら内側磁気車11および外側磁気車21の互いに異なる磁極、すなわちＳ極帯14とＮ極帯15とを向かい合わせた状態で、これら内側磁気車11および外側磁気車21を同一の軸体７に軸止めさせることもできる。 Further, as shown in FIG. 2, the inner magnetic wheel 11 and the outer magnetist 21 are respectively placed in a state where the north pole 15 of the inner magnetic wheel 11 and the north pole 15 of the outer magnetic wheel 21 face each other. Although the same shaft body 7 is fixed to the shaft, the inner magnetic wheel 11 and the outer magnetic wheel 21 are different from each other, that is, with the S pole zone 14 and the N pole zone 15 facing each other. The outer magnetic wheel 21 can be fixed to the same shaft body 7.
この場合、これら内側磁気車11および外側磁気車21の互いに異なる磁極同士を向かい合わせることにより、これら内側磁気車11と外側磁気車21との間に軸方向に沿って磁気的に引き合う力が生じるから、これら内側磁気車11および外側磁気車21のそれぞれがより容易に同一の軸体７により固定しやすくなる。 In this case, by causing the different magnetic poles of the inner magnetic wheel 11 and the outer magnetic wheel 21 to face each other, a magnetically attractive force is generated between the inner magnetic wheel 11 and the outer magnetic wheel 21 along the axial direction. Therefore, each of the inner magnetic wheel 11 and the outer magnetic wheel 21 can be more easily fixed by the same shaft body 7.
また、図２に示すように、これら内側磁気車11および外側磁気車21の外周面11a,21aに形成されているＳ極帯14およびＮ極帯15のそれぞれが搬送方向Ｆに向けて逆ハの字状に広がるように螺旋状に巻回させたが、これら内側磁気車11および外側磁気車21の外周面11a,21aに形成されているＳ極帯14およびＮ極帯15のそれぞれを逆向きに巻回させて、これらＳ極帯14およびＮ極帯15を搬送方向Ｆに向けてハの字状に狭まるように螺旋状に巻回させた構成とすることもできる。 Further, as shown in FIG. 2, each of the S pole band 14 and the N pole band 15 formed on the outer peripheral surfaces 11a and 21a of the inner magnetic wheel 11 and the outer magnetic wheel 21 is reversed toward the transport direction F. The S pole band 14 and the N pole band 15 formed on the outer peripheral surfaces 11a and 21a of the inner magnetic wheel 11 and the outer magnetic wheel 21 are reversed. The S-pole band 14 and the N-pole band 15 may be wound in a spiral direction so that the S-pole band 14 and the N-pole band 15 are narrowed in a C shape toward the transport direction F.
この場合、これら内側磁気車11および外側磁気車21のＳ極帯14およびＮ極帯15を搬送方向Ｆに向けてハの字状に狭まるように螺旋状に巻回させることにより、これら内側磁気車11の外周面11a同士に作用する磁力、および外側磁気車21の外周面21a同士に作用する磁力のそれぞれをより大きくできるので、これら内側磁気車11および外側磁気車21をより確実に連動できる。 In this case, the S magnetic pole 11 and the N magnetic pole 15 of the inner magnetic wheel 11 and the outer magnetic wheel 21 are spirally wound toward the conveying direction F so as to be narrowed in a letter C shape. Since the magnetic force acting between the outer peripheral surfaces 11a of the vehicle 11 and the magnetic force acting between the outer peripheral surfaces 21a of the outer magnetic wheels 21 can be increased, the inner magnetic wheel 11 and the outer magnetic wheel 21 can be linked more reliably. .
