本発明の一実施の形態について図面を参照して説明する。 An embodiment of the present invention will be described with reference to the drawings.

図８および図９において、１は搬送装置で、この搬送装置１は、例えば物品Ｗを搬送方向に向けて搬送するマグネット駆動式のアキュームローラコンベヤである。 8 and 9, reference numeral 1 denotes a transport device, and the transport device 1 is, for example, a magnet-driven accumulator roller conveyor that transports the article W in the transport direction.

搬送装置１は、図８および図９に示されるように、コンベヤフレーム２を備え、このコンベヤフレーム２には、所定方向に回転しながら物品Ｗを搬送方向に向けて搬送する複数の搬送ローラ３が回転可能に設けられている。 As shown in FIGS. 8 and 9, the transport device 1 includes a conveyor frame 2, and the conveyor frame 2 includes a plurality of transport rollers 3 that transport the articles W in the transport direction while rotating in a predetermined direction. Is rotatably provided.

各搬送ローラ３は、平面視で搬送方向と直交する方向に長手状をなす丸軸状のローラ軸部４と、このローラ軸部４の外周側に回転可能に装着されその軸方向に並ぶ短筒状の複数のローラ円筒部５とを有している。ローラ軸部４の軸方向端部近傍の外周側には、このローラ軸部４と一体となって回転する短筒状をなす円筒状の従動磁石体（従動マグネット）６がローラ軸部４と同心状に取り付けられている。 Each of the transport rollers 3 has a round shaft-shaped roller shaft portion 4 that is elongated in a direction orthogonal to the transport direction in plan view, and a short shaft that is rotatably mounted on the outer peripheral side of the roller shaft portion 4 and aligned in the axial direction. A plurality of cylindrical roller cylindrical portions 5 are provided. On the outer peripheral side in the vicinity of the axial end of the roller shaft 4, a cylindrical driven magnet body (driven magnet) 6 having a short cylindrical shape that rotates integrally with the roller shaft 4 is connected to the roller shaft 4. It is attached concentrically.

また、搬送装置１は、コンベヤフレーム２の軸受部８にて回転可能に支持された断面円形で丸軸状の軸体であるドライブシャフト10を備え、このドライブシャフト10は、搬送方向に長手状をなすもので、平面視で搬送ローラ３のローラ軸部４と直交するように配設されている。ドライブシャフト10は、軸方向一端部から軸方向他端部にわたって等径状のもので、その外周面が円筒面状に形成されている。 Further, the transport device 1 includes a drive shaft 10 which is a circular shaft having a circular cross section and is rotatably supported by the bearing portion 8 of the conveyor frame 2, and the drive shaft 10 is long in the transport direction. And is arranged so as to be orthogonal to the roller shaft portion 4 of the transport roller 3 in plan view. The drive shaft 10 has an equal diameter from one end in the axial direction to the other end in the axial direction, and an outer peripheral surface thereof is formed in a cylindrical shape.

ドライブシャフト10における軸方向に等間隔をおいた複数箇所の外周側には、このドライブシャフト10と一体となって回転する短筒状をなす円筒状の被取付物としての磁石体である駆動磁石体（駆動マグネット）11がドライブシャフト10と同心状に取り付けられている。 A drive magnet which is a magnet body as a cylindrical attached object having a short cylindrical shape which rotates integrally with the drive shaft 10 on the outer peripheral side of a plurality of locations at equal intervals in the axial direction of the drive shaft 10 A body (drive magnet) 11 is mounted concentrically with the drive shaft 10.

つまり、ドライブシャフト10の外周面のうち各搬送ローラ３と対応する箇所には、軸方向両端面が開口した円筒状の駆動磁石体11が２部材からなる円筒状のカラー体である取付体13のみによって脱着可能に取り付けられている。なお、駆動磁石体11は、所定以上の手動力によりドライブシャフト10に対してその軸方向に沿って移動調整可能となっている。 In other words, in the portion corresponding to each of the conveying rollers 3 on the outer peripheral surface of the drive shaft 10, a cylindrical driving magnet body 11 having both axial end surfaces opened is a mounting body 13 which is a cylindrical collar body composed of two members. Removably attached only by. The drive magnet body 11 can be moved and adjusted along the axial direction with respect to the drive shaft 10 by a predetermined manual force.

駆動磁石体11は、対応する従動磁石体６の下方にその従動磁石体６と近接状に位置しているが、これら駆動磁石体11の外周面と従動磁石体６の外周面とは非接触である。駆動磁石体11の外周面には永久磁石のＮ極帯とＳ極帯とが交互に螺旋状に設けられ、これに対応して従動磁石体６の外周面にも永久磁石のＮ極帯とＳ極帯とが交互に螺旋状に設けられている。 The drive magnet body 11 is positioned below the corresponding driven magnet body 6 in proximity to the driven magnet body 6, but the outer peripheral surface of the drive magnet body 11 and the outer peripheral surface of the driven magnet body 6 are not in contact with each other. It is. On the outer peripheral surface of the drive magnet body 11, the N pole band and the S pole band of the permanent magnet are alternately provided in a spiral shape, and the N pole band of the permanent magnet is also provided on the outer peripheral surface of the driven magnet body 6 correspondingly. S poles are alternately provided in a spiral shape.

そして、ドライブシャフト10が、モータ15等にて構成された駆動手段14の動力により駆動磁石体11と一体となって回転すると、従動磁石体６が駆動磁石体11からの磁力によりローラ軸部４と一体となって回転し、その結果、搬送ローラ３のローラ円筒部５が所定方向に回転しながら物品Ｗを搬送方向に向けて搬送する。 When the drive shaft 10 is rotated integrally with the drive magnet body 11 by the power of the drive means 14 constituted by the motor 15 and the like, the driven magnet body 6 is rotated by the magnetic force from the drive magnet body 11 to the roller shaft portion 4. As a result, the roller cylindrical portion 5 of the transport roller 3 transports the article W in the transport direction while rotating in a predetermined direction.

また、図１および図２にも示されるように、駆動磁石体11は、その外周面が円筒面状に形成され、その内周面が略円筒面状に形成されている。つまり、駆動磁石体11の外周面は円筒面状の円筒面部分21のみで構成され、駆動磁石体11の内周面は、空回り防止用の矩形状の平面部分22と、軸方向視で略Ｃ字状をなす円弧面部分23とにて構成されている。 As shown in FIGS. 1 and 2, the drive magnet body 11 has an outer peripheral surface formed in a cylindrical surface, and an inner peripheral surface formed in a substantially cylindrical surface. That is, the outer peripheral surface of the drive magnet body 11 is composed only of the cylindrical surface portion 21 having a cylindrical surface, and the inner peripheral surface of the drive magnet body 11 is substantially the same as the rectangular planar portion 22 for preventing idling and viewed in the axial direction. It is comprised by the circular arc surface part 23 which makes | forms C shape.

取付体13は、図１および図２等に示されるように、例えば軸方向両端面が開口した短筒状で円筒状（略円筒状を含む）をなす同一形状の合成樹脂製の２つの筒状部材、すなわち互いに同一形状に形成された第１筒状部材31および第２筒状部材32によって構成されている。 As shown in FIGS. 1 and 2, etc., the attachment body 13 is, for example, a short cylindrical shape having both ends in the axial direction opened, and two cylindrical tubes made of synthetic resin having the same shape (including a substantially cylindrical shape). It is comprised by the 1st cylindrical member 31 and the 2nd cylindrical member 32 which were formed in the shape member, ie, the mutually same shape.

つまり、取付体13は、内周側がドライブシャフト10の外周面に所定の圧着力によって圧着固定されかつ外周側に駆動磁石体11の軸方向一端側が嵌合配設される円筒状の第１筒状部材31と、この第１筒状部材31と同一形状に形成されこの第１筒状部材31にこの第１筒状部材31の向きとは反対の向きで脱着可能に嵌合装着され内周側がドライブシャフト10の外周面に所定の圧着力によって圧着固定されかつ外周側に駆動磁石体11の軸方向他端側が嵌合配設される円筒状の第２筒状部材32とを備えている。 In other words, the mounting body 13 is a cylindrical first cylinder whose inner peripheral side is crimped and fixed to the outer peripheral surface of the drive shaft 10 by a predetermined pressing force and one axial end side of the drive magnet body 11 is fitted and disposed on the outer peripheral side. The first cylindrical member 31 is formed in the same shape as the first cylindrical member 31, and is fitted and detachably attached to the first cylindrical member 31 in a direction opposite to the direction of the first cylindrical member 31. A cylindrical second cylindrical member 32 whose side is crimped and fixed to the outer circumferential surface of the drive shaft 10 by a predetermined crimping force and whose other axial end side of the drive magnet body 11 is fitted and disposed on the outer circumferential side. .

なお、これら２つの筒状部材31，32は、互いに嵌合装着されることによりそれらの各内周面の一部が金属製のドライブシャフト10の外周面に所定の圧着力によって圧着固定されるが、所定の圧着力以上の手動力によって両筒状部材31，32を互いに嵌合装着した状態のままドライブシャフト10の外周面に沿ってその軸方向にスライド移動させることが可能となっている。 The two cylindrical members 31 and 32 are fitted and mounted to each other so that a part of their inner peripheral surfaces is fixed to the outer peripheral surface of the metal drive shaft 10 by a predetermined pressing force. However, the cylindrical members 31 and 32 can be slid in the axial direction along the outer peripheral surface of the drive shaft 10 while being fitted and attached to each other by a manual force equal to or greater than a predetermined pressure. .

ここで、筒状部材31，32の具体的な形状について説明すると、図１ないし図４に示されるように、筒状部材31，32は、外周側に駆動磁石体11が回転不能に嵌合配設され内周側がドライブシャフト10の外周面から離間して位置する筒状部35を有している。 Here, the specific shape of the cylindrical members 31 and 32 will be described. As shown in FIGS. 1 to 4, the cylindrical members 31 and 32 are fitted on the outer peripheral side so that the drive magnet body 11 cannot rotate. It has a cylindrical portion 35 that is disposed and whose inner peripheral side is located away from the outer peripheral surface of the drive shaft 10.

筒状部35は、軸方向両端面が開口した円筒状（略円筒状を含む）に形成されている。筒状部35の内周面における周方向に間隔をおいた複数箇所、すなわち例えば周方向に等間隔をおいた３箇所には、内面の一部である先端側がドライブシャフト10の外周面に圧着固定される円弧板状の板状部36がその先端側が筒状部35の軸方向一端部から突出するように一体に突設されている。なお、周方向に互いに隣り合う弾性変形可能な板状部36間には、板状部36が入り込む板状部嵌入用の空間部40が存在する。 The cylindrical portion 35 is formed in a cylindrical shape (including a substantially cylindrical shape) in which both axial end surfaces are open. At a plurality of locations spaced in the circumferential direction on the inner circumferential surface of the cylindrical portion 35, that is, for example, at three locations spaced equally in the circumferential direction, the tip side that is a part of the inner surface is crimped to the outer circumferential surface of the drive shaft 10 A fixed arcuate plate-like plate-like portion 36 is integrally projected so that the tip end side thereof protrudes from one axial end portion of the cylindrical portion 35. Between the elastically deformable plate-like portions 36 adjacent to each other in the circumferential direction, there is a space portion 40 for inserting the plate-like portion into which the plate-like portion 36 is inserted.

また、筒状部35の外周面における軸方向他端部には、駆動磁石体11の軸方向端面との当接によりこの駆動磁石体11の軸方向に沿った移動を規制する鍔状の移動規制部37が筒状部35の径方向外方に突出するように一体に突設されている。 Further, the other end in the axial direction on the outer peripheral surface of the cylindrical portion 35 is a saddle-like movement that restricts the movement of the drive magnet body 11 along the axial direction by contact with the axial end face of the drive magnet body 11. The restricting portion 37 is integrally projected so as to protrude outward in the radial direction of the cylindrical portion 35.

筒状部35の外周面は、駆動磁石体11の内周面の平面部分22と面接触して駆動磁石体11の筒状部35に対する回転を不能にする空回り防止用の矩形状の平面部分（背切り）41を有している。また、筒状部35の外周面は、駆動磁石体11の内周面の円弧面部分23と隙間なく嵌合する軸方向視略Ｃ字状の円弧面部分42を有している。つまり、この筒状部35の外周面は、平面部分41と、円弧面部分42とにて構成されている。 The outer peripheral surface of the cylindrical portion 35 is in rectangular contact with the flat portion 22 of the inner peripheral surface of the drive magnet body 11 to prevent rotation of the drive magnet body 11 with respect to the cylindrical portion 35 to prevent idling. (Back-cut) 41 is provided. Further, the outer peripheral surface of the cylindrical portion 35 has a substantially C-shaped arcuate surface portion 42 in the axial direction that fits with the arcuate surface portion 23 of the inner peripheral surface of the drive magnet body 11 without a gap. That is, the outer peripheral surface of the cylindrical portion 35 is configured by the flat surface portion 41 and the arc surface portion 42.

筒状部35の円筒状の内周面のうち板状部36が設けられていない部分には、この筒状部35の周方向に長手方向を有する長手状で断面矩形状の凸部分43が形成されている。つまり、筒状部35は、周方向に等間隔をおいた複数、例えば３つの長手状の凸部分43を軸方向一部の内周面に有し、この各凸部分43の長手方向一端部が互いに隣り合う板状部36のうちの一方の板状部36に近接し、その長手方向他端部が互いに隣り合う板状部36のうちの他方の板状部36に近接している。 A portion of the cylindrical inner surface of the cylindrical portion 35 where the plate-like portion 36 is not provided has a convex portion 43 having a longitudinal shape and a rectangular section having a longitudinal direction in the circumferential direction of the cylindrical portion 35. Is formed. That is, the cylindrical portion 35 has a plurality of, for example, three longitudinal convex portions 43 that are equally spaced in the circumferential direction on the inner circumferential surface of a part in the axial direction, and one longitudinal end portion of each convex portion 43. Is adjacent to one plate-like portion 36 of the plate-like portions 36 adjacent to each other, and the other longitudinal end portion is close to the other plate-like portion 36 of the plate-like portions 36 adjacent to each other.

また、板状部36は、円筒状の筒状部35と同心状の円弧板状に形成されており、この板状部36の基端側部分36aが筒状部35の内周面に一体に設けられ、この板状部36の先端側部分36bが筒状部35の軸方向一端部から軸方向一方に向かって突出している。板状部36の内面は、ドライブシャフト10の外周面の一部と面接触するように円弧面状に形成されている。 Further, the plate-like portion 36 is formed in a circular arc plate shape concentric with the cylindrical tubular portion 35, and the base end side portion 36 a of the plate-like portion 36 is integrated with the inner peripheral surface of the tubular portion 35. The distal end portion 36b of the plate-like portion 36 protrudes from one axial end portion of the cylindrical portion 35 toward one axial direction. The inner surface of the plate-like portion 36 is formed in a circular arc shape so as to come into surface contact with a part of the outer peripheral surface of the drive shaft 10.

板状部36の外面には、筒状部35の周方向に長手方向を有する長手状の凹部分44が形成されている。つまり、３つの各板状部36は、筒状部35の凸部分43が入り込んでこの凸部分43と係脱可能に係合する長手状の凹部分44を外面に有している。 On the outer surface of the plate-like portion 36, a longitudinal concave portion 44 having a longitudinal direction in the circumferential direction of the tubular portion 35 is formed. That is, each of the three plate-like portions 36 has a longitudinal concave portion 44 on the outer surface thereof, into which the convex portion 43 of the cylindrical portion 35 enters and is detachably engaged with the convex portion 43.

また、板状部36の外面のうち凹部分44よりも先端側に位置する部分が、先端に向かって徐々に縮径する先細テーパ状である傾斜面状の案内面45となっており、この案内面45は凸部分43を凹部分44に向けて案内するものである。なお、板状部36の圧着部である先端側部分36bの板厚寸法は、先端ほど小さくなっている。 Further, a portion of the outer surface of the plate-like portion 36 that is located on the tip side of the concave portion 44 is an inclined guide surface 45 that is a tapered shape that gradually decreases in diameter toward the tip. The guide surface 45 guides the convex portion 43 toward the concave portion 44. It should be noted that the plate thickness dimension of the distal end side portion 36b, which is the pressure-bonding portion of the plate-like portion 36, is smaller toward the distal end.

そして、図２および図５に示すように、外周側に駆動磁石体11が嵌合配設されかつ内周側にドライブシャフト10が嵌合挿入された第１筒状部材31側に向けて、その第１筒状部材31とは反対の向きの第２筒状部材32をドライブシャフト10の外周面に沿ってスライド移動させると、第２筒状部材32の板状部36が第１筒状部材31の空間部40に入り込むとともに、第１筒状部材31の板状部36が第２筒状部材32の空間部40に入り込む。 Then, as shown in FIGS. 2 and 5, toward the first cylindrical member 31 side in which the drive magnet body 11 is fitted and disposed on the outer peripheral side and the drive shaft 10 is fitted and inserted on the inner peripheral side, When the second cylindrical member 32 opposite to the first cylindrical member 31 is slid along the outer peripheral surface of the drive shaft 10, the plate-like portion 36 of the second cylindrical member 32 is in the first cylindrical shape. While entering the space portion 40 of the member 31, the plate-like portion 36 of the first cylindrical member 31 enters the space portion 40 of the second cylindrical member 32.

すると、図６に示すように、筒状部35の凸部分43が、案内面45上を摺動して板状部36の凹部分44に入り込んでこの凹部分44と係合する。 Then, as shown in FIG. 6, the convex portion 43 of the cylindrical portion 35 slides on the guide surface 45 and enters the concave portion 44 of the plate-like portion 36 to engage with the concave portion 44.

その結果、両筒状部材31，32の６つの板状部36の先端側部分36bが凸部分43によって径方向内方に押圧され、この押圧により各先端側部分36bの内面がドライブシャフト10の外周面にその全周にわたって圧着固定される。 As a result, the tip side portions 36b of the six plate-like portions 36 of both the cylindrical members 31 and 32 are pressed radially inward by the convex portions 43, and the inner surfaces of the tip side portions 36b of the drive shaft 10 are thereby pressed. It is crimped and fixed to the outer peripheral surface over its entire circumference.

なお、この状態のまま所定以上の手動力によって先端側部分36bの内面をドライブシャフト10の外周面に沿ってその軸方向にスライド移動させることが可能である。また、この圧着固定時において、板状部36の先端側部分36bの外面と筒状部35の内面との間には、若干の隙間46がある。 In this state, the inner surface of the tip end portion 36b can be slid in the axial direction along the outer peripheral surface of the drive shaft 10 by a predetermined manual force or more. In addition, there is a slight gap 46 between the outer surface of the distal end side portion 36b of the plate-like portion 36 and the inner surface of the cylindrical portion 35 at the time of this crimping and fixing.

また、駆動磁石体11の移動を規制する鍔状の移動規制部37のうち平面部分41に近接して位置する部分には、駆動磁石体11の平面部分22と筒状部材31，32の平面部分41との位置合わせを容易にするための位置確認部である凹部50が形成されている。 Further, in the portion of the bowl-shaped movement restricting portion 37 that restricts the movement of the drive magnet body 11 and located near the plane portion 41, the plane portion 22 of the drive magnet body 11 and the planes of the cylindrical members 31, 32 are provided. A concave portion 50 is formed as a position confirmation portion for facilitating alignment with the portion 41.

なお、両筒状部材31，32が互いに嵌合装着、つまり嵌着された状態で、第１筒状部材31の移動規制部37と第２筒状部材32の移動規制部37との間の距離は、駆動磁石体11の軸方向長さ寸法と同じ（略同じを含む）である。また、取付体13の内径寸法はドライブシャフト10の外径寸法よりも若干小さい。 In addition, in a state in which both the cylindrical members 31 and 32 are fitted and attached to each other, that is, in a fitted state, between the movement restricting portion 37 of the first tubular member 31 and the movement restricting portion 37 of the second tubular member 32. The distance is the same as the axial length of the drive magnet body 11 (including substantially the same). Further, the inner diameter dimension of the mounting body 13 is slightly smaller than the outer diameter dimension of the drive shaft 10.

次に、上記取付体13の作用等を説明する。 Next, the operation and the like of the mounting body 13 will be described.

磁石取付具である取付体13を用いて、駆動磁石体11をドライブシャフト10に固定的に取り付ける場合には、まず、作業者は、両筒状部材31，32のうちのいずれか一方、例えば第１筒状部材31の筒状部35を駆動磁石体11内に嵌合挿入し、移動規制部37を駆動磁石体11の端面に当接させる。つまり、駆動磁石体11の平面部分22と第１筒状部材31の平面部分41との位置合わせをしてから、第１筒状部材31の筒状部35の外周側に、駆動磁石体11をその筒状部35に対して回転不能に取り付ける。 When the drive magnet body 11 is fixedly attached to the drive shaft 10 using the attachment body 13 which is a magnet attachment tool, first, the operator first selects either one of the cylindrical members 31, 32, for example, The tubular portion 35 of the first tubular member 31 is fitted and inserted into the drive magnet body 11, and the movement restricting portion 37 is brought into contact with the end surface of the drive magnet body 11. That is, after aligning the flat portion 22 of the drive magnet body 11 and the flat portion 41 of the first cylindrical member 31, the drive magnet body 11 is disposed on the outer peripheral side of the cylindrical portion 35 of the first cylindrical member 31. Is attached to the cylindrical portion 35 in a non-rotatable manner.

次いで、作業者は、例えば図２に示すように、駆動磁石体11が取り付けられた第１筒状部材31の筒状部35内にドライブシャフト10を嵌合挿入するとともに、駆動磁石体11が取り付けられていない第２筒状部材32の筒状部35内にドライブシャフト10を嵌合挿入する。 Next, for example, as shown in FIG. 2, the operator fits and inserts the drive shaft 10 into the cylindrical portion 35 of the first cylindrical member 31 to which the drive magnet body 11 is attached. The drive shaft 10 is fitted and inserted into the cylindrical portion 35 of the second cylindrical member 32 that is not attached.

そして、第１筒状部材31を所望位置に位置決めした後、第２筒状部材32をドライブシャフト10の外周面に沿ってスライド移動させ、これら第１筒状部材31と第２筒状部材32とを互いに嵌合させる。 And after positioning the 1st cylindrical member 31 in a desired position, the 2nd cylindrical member 32 is slid along the outer peripheral surface of the drive shaft 10, and these 1st cylindrical member 31 and the 2nd cylindrical member 32 are moved. And mate with each other.

すると、板状部36の凹部分44と筒状部35の凸部分43とが互いに嵌合して係合し、その結果、両筒状部材31，32の板状部36の先端側部分36bが凸部分43にて押され、この先端側部分36bの内面がドライブシャフト10の外周面に圧着固定され、また同時に、駆動磁石体11が両筒状部材31，32の鍔状の移動規制部37にて両側から挟持固定される（図６参照）。 Then, the concave portion 44 of the plate-like portion 36 and the convex portion 43 of the tubular portion 35 are fitted and engaged with each other, and as a result, the distal end side portion 36b of the plate-like portion 36 of both the cylindrical members 31, 32. Is pushed by the convex portion 43, and the inner surface of the tip side portion 36b is crimped and fixed to the outer peripheral surface of the drive shaft 10, and at the same time, the drive magnet body 11 is a saddle-like movement restricting portion of both the cylindrical members 31, 32. It is clamped and fixed from both sides at 37 (see FIG. 6).

なお、この図６に示す状態のまま所定以上の手動力を加えることでドライブシャフト10の外周面に対する両筒状部材31，32の圧着固定位置を調整できるが、両筒状部材31，32同士の嵌合を一旦解除すれば両筒状部材31，32の位置調整を容易に行うことができる。 In addition, by applying a manual force of a predetermined level or more in the state shown in FIG. 6, the crimping fixing positions of the two cylindrical members 31, 32 with respect to the outer peripheral surface of the drive shaft 10 can be adjusted. Once the fitting is released, the positions of both cylindrical members 31 and 32 can be easily adjusted.

また一方、作業者は、例えば図７に示すように、駆動磁石体11が取り付けられた第１筒状部材31に対して第２筒状部材32を嵌着してから、これら両筒状部材31，32内にドライブシャフト10を押し込むように嵌合挿入してもよい。 On the other hand, as shown in FIG. 7, for example, the operator fits the second cylindrical member 32 to the first cylindrical member 31 to which the drive magnet body 11 is attached, and then both these cylindrical members. The drive shaft 10 may be fitted and inserted into 31 and 32.

このように同一形状の両筒状部材31，32を用いて複数個の駆動磁石体11を１本のドライブシャフト10の各所望位置に取り付ける等して、搬送装置１を組み立てる。 In this way, the conveying device 1 is assembled by attaching a plurality of drive magnet bodies 11 to each desired position of one drive shaft 10 by using both cylindrical members 31 and 32 having the same shape.

そして、搬送装置１による物品Ｗの搬送時には、ドライブシャフト10が駆動手段14の動力により複数個の駆動磁石体11と一体となって回転する。 When the article W is conveyed by the conveying device 1, the drive shaft 10 rotates integrally with the plurality of drive magnet bodies 11 by the power of the driving means 14.

すると、対応した従動磁石体６が駆動磁石体11からの磁力を受けてローラ軸部４と一体となって回転し、その結果、物品Ｗが搬送ローラ３のローラ円筒部５にて搬送方向へ搬送される。 Then, the corresponding driven magnet body 6 receives the magnetic force from the drive magnet body 11 and rotates integrally with the roller shaft portion 4, and as a result, the article W moves in the transport direction at the roller cylindrical portion 5 of the transport roller 3. Be transported.

そして、上記搬送装置１の取付体13によれば、その取付体13を構成する第１筒状部材31と第２筒状部材32とが互いに同一形状に形成されているため、これら第１筒状部材31と第２筒状部材32とを区別して管理する必要がなく、部品管理が容易であり、組み立て性も良好である。 And according to the attachment body 13 of the said conveying apparatus 1, since the 1st cylindrical member 31 and the 2nd cylindrical member 32 which comprise the attachment body 13 are mutually formed in the same shape, these 1st cylinders It is not necessary to distinguish and manage the cylindrical member 31 and the second cylindrical member 32, the parts management is easy, and the assemblability is also good.

また、１種類の金型によって両筒状部材31，32を成形できるから、金型費用を安くでき、製造コストの低減を図ることができる。 Moreover, since both the cylindrical members 31 and 32 can be molded by one type of mold, the mold cost can be reduced and the manufacturing cost can be reduced.

さらに、両筒状部材31，32の凹部分44と凸部分43との係合により第１筒状部材31の内周側および第２筒状部材32の内周側がドライブシャフト10の外周面に圧着固定されるため、第１筒状部材31および第２筒状部材32の両方をドライブシャフト10の外周面に対して所定の圧着力（締め付け力）で適切に圧着固定できる。 Furthermore, the inner peripheral side of the first cylindrical member 31 and the inner peripheral side of the second cylindrical member 32 are brought to the outer peripheral surface of the drive shaft 10 by the engagement of the concave portions 44 and the convex portions 43 of both the cylindrical members 31 and 32. Since the first and second cylindrical members 31 and 32 are fixed by crimping, both the first and second cylindrical members 31 and 32 can be appropriately crimped and fixed to the outer peripheral surface of the drive shaft 10 with a predetermined crimping force (tightening force).

また、両筒状部材31，32は、抜止め用の移動規制部37および空回り防止用の平面部分（背切り）41を有するため、両筒状部材31，32同士の嵌合装着により駆動磁石体11の両筒状部材31，32に対する空回りを適切に防止できるとともに駆動磁石体11の抜けを適切に防止できる。 Moreover, since both the cylindrical members 31 and 32 have a movement restricting portion 37 for retaining and a flat surface portion (back cut) 41 for preventing idling, the drive magnets are fitted by fitting the both cylindrical members 31 and 32 together. The idle rotation of the body 11 with respect to both the cylindrical members 31 and 32 can be prevented appropriately, and the drive magnet body 11 can be prevented from coming off properly.

さらに、両筒状部材31，32内にドライブシャフト10を挿通した状態で、両筒状部材31，32同士を互いに嵌合させることができるため、ドライブシャフト10に対する駆動磁石体11の位置調整を容易に行うことができる。 Furthermore, since the cylindrical members 31 and 32 can be fitted to each other with the drive shaft 10 inserted into the cylindrical members 31 and 32, the position of the drive magnet body 11 relative to the drive shaft 10 can be adjusted. It can be done easily.

なお、上記実施の形態では、筒状部35が凸部分43を内周面に有しかつ板状部36が凹部分44を外面に有する構成について説明したが、例えば筒状部35が凹部分44を内周面に有しかつ板状部36が凸部分43を外面に有する構成等でもよい。 In the above-described embodiment, the configuration in which the cylindrical portion 35 has the convex portion 43 on the inner peripheral surface and the plate-like portion 36 has the concave portion 44 on the outer surface has been described. For example, the cylindrical portion 35 has the concave portion. The structure etc. which have 44 on the inner peripheral surface and plate-like part 36 has the convex part 43 on the outer surface may be sufficient.

また、例えば凸部分43が凹部分44に対して隙間なく嵌合するようにしてもよく、また、凸部分43および凹部分44の形状は長手状には限定されず、例えば円形状等でもよい。 Further, for example, the convex portion 43 may be fitted to the concave portion 44 without a gap, and the shape of the convex portion 43 and the concave portion 44 is not limited to the longitudinal shape, and may be, for example, a circular shape. .

さらに、筒状部材31，32がそれぞれ有する板状部36の数は、３つには限定されず、例えば１つでもよく、２つや４つ以上でもよい。 Furthermore, the number of the plate-like portions 36 included in each of the cylindrical members 31 and 32 is not limited to three, and may be one, for example, two or four or more.

また、例えば上記搬送装置１において、駆動磁石体11のみでなく、取付体13を用いて筒状の従動磁石体（被取付物）６を搬送ローラ３の丸軸状のローラ軸部（軸体）４に取り付けるようにしてもよい。 Further, for example, in the transport device 1, not only the drive magnet body 11 but also the mounting body 13 is used to connect the cylindrical driven magnet body (attachment) 6 to the round shaft roller shaft portion (shaft body) of the transport roller 3. ) You may make it attach to 4.

さらに、取付体13によって軸体に取り付けられる被取付物は、駆動磁石体や従動磁石体等の磁石体（永久磁石）以外に、例えばプーリやスプロケット等でもよい。 Furthermore, the attachment object attached to the shaft body by the attachment body 13 may be, for example, a pulley or a sprocket other than a magnet body (permanent magnet) such as a drive magnet body or a driven magnet body.

さらに、取付体13は、アキューム機能を有しない通常のローラコンベヤにも適用でき、またローラコンベヤ等の搬送装置以外の他の装置にも適用可能である。 Furthermore, the attachment 13 can be applied to a normal roller conveyor that does not have an accumulating function, and can also be applied to devices other than a conveying device such as a roller conveyor.
