Description

本発明はローラタイプの振り分けコンベヤに係り、更に詳しくは搬送ローラが磁力を利用した非接触型の動力伝達方式で駆動回転され、大型で比較的重量の重い搬送物を振り分け搬送するのに適した振り分けコンベヤに関する。   The present invention relates to a roller-type sorting conveyor, and more specifically, the conveyance roller is driven and rotated by a non-contact type power transmission system using magnetic force, and is suitable for sorting and conveying a large and relatively heavy conveyance object. It relates to a sorting conveyor.

平面視方形の枠体内に、平面視略円形の筒枠を回転可能に支持し、その筒枠の内側に磁石を内蔵した搬送ローラを複数本平行に横架して搬送面を構成し、前記搬送ローラを磁力を利用した非接触型の動力伝達方式で回転すると共に、前記筒枠を回転機構で水平旋回するようにしたローラ式搬送装置は、本件出願人が提案済みである(特許文献1参照)。   In a rectangular frame in plan view, a substantially circular cylindrical frame in plan view is rotatably supported, and a plurality of conveyance rollers containing magnets are installed in parallel inside the cylindrical frame to form a conveyance surface, The applicant of the present invention has proposed a roller-type transfer device in which the transfer roller is rotated by a non-contact type power transmission method using magnetic force and the cylindrical frame is horizontally rotated by a rotation mechanism (Patent Document 1). reference).

その特許文献1に記載のローラ式搬送装置は、比較的軽量で小型の搬送物、例えば箱入の菓子等が対象であり、その為に筒枠内に横架された搬送ローラを駆動する磁力を利用した非接触型の動力伝達を行う駆動磁気車は1本で、しかも該駆動磁気車の外径も小さいもの(例えば、φ20前後)で十分であった。   The roller-type conveying device described in Patent Document 1 is intended for relatively light and small conveyed items, such as boxed confectionery, and for that purpose, a magnetic force that drives a conveying roller horizontally mounted in a cylindrical frame. A single drive magnetic wheel that performs non-contact power transmission using the motor and that has a small outer diameter (for example, around φ20) is sufficient.

しかし、大型で比較的重量の重い(例えば、30〜35kg程度)搬送物を搬送しようとした場合、前記した小径の駆動磁気車1本では搬送に必要な十分なトルク(動力)を得ることは困難であり、そのために駆動磁気車の外径を大きくすることで搬送に必要なトルクを得る方策も考えられる。その場合、駆動磁気車の外径を大きくするということは、その動力伝達に関係する部分も大きくなり、動力伝達部分が大型化するという問題点を有する。   However, when trying to transport a large and relatively heavy (for example, about 30 to 35 kg) transported object, it is not possible to obtain sufficient torque (power) necessary for transport with one small-diameter driving magnetic wheel. For this reason, it is conceivable to increase the outer diameter of the drive magnetic wheel so as to obtain torque necessary for conveyance. In that case, increasing the outer diameter of the drive magnetic wheel has a problem that the portion related to the power transmission becomes larger and the power transmission portion becomes larger.

特開2005−272102号公報JP 2005-272102 A

本発明は上記した従来の技術が有する問題点に鑑みてなされたもので、その課題とするところは、磁力を利用した非接触型の動力伝達機構を備えたローラタイプの振り分けコンベヤであって、コンパクトな動力伝達機構でありながら大型大重量の搬送物に対応可能な振り分けコンベヤを提供することにある。   The present invention has been made in view of the above-described problems of the prior art, and the subject is a roller type sorting conveyor provided with a non-contact power transmission mechanism using magnetic force, An object of the present invention is to provide a sorting conveyor capable of handling a large and heavy transported object while being a compact power transmission mechanism.

上記課題を達成する為に本発明が講じた技術的手段は、非磁性体からなる筒状体の内部に、永久磁石のリングを該筒状体の軸芯方向に沿って複数個を嵌合固定し、筒状体の軸方向の両側内側には軸受を嵌着固定し、その両側の軸受に亘って支軸を嵌装して前記筒状体を回転自在とした搬送ローラを、平面視円形叉は円形に近似した筒枠状のフレームの内側に、該フレームの略中心を通る位置から直交するフレームの周壁方向に向かって、漸次ローラ長に変化を付け、所定間隔を置いて並列に配置して平面視略円形の搬送面を構成すると共に、その並列配置した各搬送ローラに内蔵する複数の永久磁石は同一線上に並ぶように配置し、更に前記各搬送ローラの各列の永久磁石と対応する位置に駆動磁気車を該ローラの外周面と非接触で且つ交差させて回転自在に接近配置し、前記各駆動磁気車を直接叉は間接的に同期回転して前記搬送ローラを回転させ、更に前記搬送ローラを備えたフレームを回転機構によって水平旋回自在としたことを特徴とする(請求項1)。   The technical means taken by the present invention to achieve the above object is to fit a plurality of permanent magnet rings inside the cylindrical body made of a non-magnetic material along the axial direction of the cylindrical body. A transport roller that is fixed and has bearings fitted and fixed inside both sides in the axial direction of the cylindrical body, and a support shaft is fitted over the bearings on both sides to make the cylindrical body rotatable. Inside the cylindrical frame that approximates a circle or circular shape, the length of the roller is gradually changed from the position passing through the approximate center of the frame toward the direction of the peripheral wall of the frame, and in parallel at a predetermined interval. A plurality of permanent magnets built in each of the conveyance rollers arranged in parallel are arranged so as to be aligned on the same line, and the permanent magnets in each row of the respective conveyance rollers are arranged. And the drive magnetic wheel at a position corresponding to the non-contact with the outer peripheral surface of the roller The drive magnetic wheels are rotated in close proximity, and each of the drive magnetic wheels is directly or indirectly synchronously rotated to rotate the transport roller, and the frame having the transport roller is horizontally rotatable by a rotation mechanism. (Claim 1).

上記筒状体内に嵌合固定する永久磁石のリングは、リングの外周面にN極とS極を螺旋状に着磁したもの、或いはリングの外周面にN極とS極を周方向に沿って交互に直線状に着磁したものなど、何れでもよい。そして、この永久磁石のリングは各搬送ローラに複数個嵌合固定するが、その内蔵するリングの位置は、駆動源から各搬送ローラへの動力伝達を考慮した場合、バラバラに配置するよりは整列配置するのが有効である。そして、各搬送ローラに複数個のリングを配置することで、各搬送ローラへの磁力による動力伝達経路を少なくとも2系統以上確保することができる。
筒状体に対する永久磁石のリングを嵌合する方法は、筒状体の周壁内側に嵌合する方式、或いは筒状体の周壁へリングの厚さの一部或いは全部を食い込ませて嵌合する方式など何れでもよい。
また、上記駆動磁気車は、長尺一本物であっても、或いは長尺の軸の外周に搬送ローラの並設ピッチと同じピッチで短尺筒状の磁気車を嵌着固定して構成したものなど何れでもよい。
更に、上記駆動磁気車を直接回転とは、モータの回転をベルト、チェーン、歯車等の動力伝達手段を介して直接回転させることを意味し、間接的回転とは回転を非接触で駆動磁気車に伝達することを意味し、例えば磁力を利用した非接触の動力伝達が挙げられる。
The ring of the permanent magnet fitted and fixed in the cylindrical body is one in which the N pole and S pole are spirally magnetized on the outer peripheral surface of the ring, or the N pole and S pole are arranged in the circumferential direction on the outer peripheral surface of the ring. Any of them may be alternately magnetized in a straight line. A plurality of rings of this permanent magnet are fitted and fixed to each conveyance roller, but the position of the built-in ring is aligned rather than disposing separately when considering the power transmission from the drive source to each conveyance roller. It is effective to arrange. By disposing a plurality of rings on each conveyance roller, it is possible to secure at least two or more power transmission paths by magnetic force to each conveyance roller.
The method of fitting the ring of the permanent magnet to the cylindrical body is a method of fitting inside the peripheral wall of the cylindrical body, or by fitting a part or all of the thickness of the ring into the peripheral wall of the cylindrical body. Any method may be used.
The drive magnetic wheel may be a single long one, or a short cylindrical magnetic wheel fitted and fixed on the outer periphery of a long shaft at the same pitch as that of the conveying rollers. Any may be sufficient.
Further, the direct rotation of the driving magnetic wheel means that the rotation of the motor is directly rotated through power transmission means such as a belt, a chain, and a gear, and the indirect rotation means that the rotation of the driving magnetic wheel is non-contact. For example, non-contact power transmission using magnetic force.

又、搬送ローラが平行に横架支持されたフレームを水平旋回させる回転機構は、前記搬送ローラを備えたフレームを固定架台に軸受を介して水平旋回可能に支持し、そのフレームを、固定架台に設置固定したモータの回転によって回転させる方式、或いはロータリーアクチュエータで回転させる方式等が挙げられる。
モータによってフレームを回転する場合の具体例としては、例えばモータの回転をタイミングプーリとタイミングベルトによるベルト伝達方式(請求項2)、或いはチェーン伝達方式、歯車伝達方式等の構成が挙げられる。
In addition, the rotation mechanism for horizontally turning the frame in which the conveyance roller is horizontally supported in parallel supports the frame provided with the conveyance roller so that the frame can be horizontally rotated through a bearing on the fixed frame, and the frame is supported on the fixed frame. Examples of the method include a method of rotating by rotating a fixed motor, a method of rotating by a rotary actuator, and the like.
Specific examples of the case in which the frame is rotated by a motor include, for example, a belt transmission system (rotation 2) using a timing pulley and a timing belt, or a chain transmission system, a gear transmission system, and the like.

前記搬送ローラに内蔵する永久磁石のリングは、各搬送ローラとも複数個で、その内蔵位置はバラバラでもよいが、該永久磁石のリングと対応配置する駆動磁気車の本数を考慮した場合は、内蔵位置を特定することが有効である。即ち、ローラ長の略中心位置から軸方向略対称位置に配置することで、各搬送ローラに内蔵された永久磁石のリングは同一線上に並び、その略対称位置の永久磁石が配列された線上真下に駆動磁気車を平行ならしめ回転可能に配置すると共に、その2本の駆動磁気車間に単一の駆動回転体を配置し、該駆動回転体の回転を動力伝達機構を介して前記駆動磁気車に伝達し、搬送ローラを回転するようにする(請求項3)。   There are a plurality of permanent magnet rings built in the transport roller, and the positions of the built-in magnets may vary, but if the number of drive magnetic wheels arranged corresponding to the permanent magnet ring is taken into account, the built-in ring It is effective to specify the position. In other words, by arranging the roller length from the approximate center position in the axial direction to the substantially symmetrical position in the axial direction, the rings of the permanent magnets built in the respective transport rollers are aligned on the same line and directly below the line where the permanent magnets at the approximately symmetrical position are arranged. The drive magnetic wheel is arranged so as to be parallel and rotatable, and a single drive rotator is arranged between the two drive magnetic wheels, and the rotation of the drive rotator is transmitted through the power transmission mechanism to the drive magnetic wheel. And the conveying roller is rotated (claim 3).

前記駆動回転体の回転を平行に配置した両駆動磁気車へ伝達する動力伝達機構としては、磁石による非接触型の動力伝達方式(請求項4)、或いは歯車の組み合わせによるもの(請求項5)など、何れでもよい。従って、駆動回転体は動力伝達機構の形態によって変わり、磁力による非接触型の動力伝達機構の場合は短筒状の磁気車(元駆動磁気車)を使用し、歯車の組み合わせによる伝達機構の場合は歯車(例えば、はすば歯車、ねじ歯車等)を使用する。   As a power transmission mechanism for transmitting the rotation of the drive rotator to both drive magnetic wheels arranged in parallel, a non-contact power transmission system using magnets (Claim 4) or a combination of gears (Claim 5) Any of these may be used. Therefore, the drive rotating body varies depending on the form of the power transmission mechanism. In the case of a non-contact power transmission mechanism using magnetic force, a short cylindrical magnetic wheel (former driving magnetic wheel) is used, and in the case of a transmission mechanism using a combination of gears. Uses gears (for example, helical gears, screw gears, etc.).

上記手段によれば、永久磁石のリングを内蔵した搬送ローラは、駆動磁気車の回転による磁極の移動により回転され、それによりフレームに横架された各搬送ローラは支軸を中心として駆動回転される。そして、その回転は、1個の駆動回転体によって駆動される複数本(2本)の駆動磁気車からの動力伝達によって駆動回転できる。即ち、駆動磁気車の外径を大きくすることなく、重量物の搬送に必要なトルクアップをコンパクトな構成で達成できる。
しかも、搬送ローラを取り付けたフレームを所定角度水平旋回することで、搬送ローラの駆動回転による搬送方向(搬送ローラの軸芯と直交する方向)を、該フレームの中心を旋回中心として周方向に自由に変更することができる。
そして、振り分けコンベヤの周囲(前後)に、一般的なローラコンベヤ等を組み合わせ配置し、フレームの水平旋回の角度を変更することで、二方向、三方向への振り分け、方向転換、搬送方向は同じで搬送物の向きを180度転換させる等、幅広い搬送システムを簡単に構成することができる。
According to the above means, the transport roller incorporating the ring of the permanent magnet is rotated by the movement of the magnetic pole by the rotation of the drive magnetic wheel, so that each transport roller mounted on the frame is driven to rotate about the support shaft. The The rotation can be driven and rotated by power transmission from a plurality (two) of driving magnetic wheels driven by one driving rotating body. That is, it is possible to achieve a torque increase necessary for transporting heavy objects with a compact configuration without increasing the outer diameter of the drive magnetic wheel.
In addition, by rotating the frame with the conveyance roller horizontally by a predetermined angle, the conveyance direction (direction perpendicular to the axis of the conveyance roller) by the rotation of the conveyance roller can be freely set in the circumferential direction with the center of the frame as the rotation center. Can be changed.
And, by arranging and arranging general roller conveyors around the sorting conveyor (front and rear) and changing the horizontal turning angle of the frame, sorting in two directions, three directions, direction change, and conveying direction are the same Thus, a wide transport system can be easily configured, for example, by changing the direction of the transported object by 180 degrees.

本発明の振り分けコンベヤは、磁力を利用した非接触型の動力伝達を大型化することなくコンパクトな構成で、重量物の搬送物に対応できるコンベヤを提供できる。
そして、請求項3〜5記載の構成により、単一の駆動回転体の回転力を2本の駆動磁気車に効率よく伝達でき、動力伝達機構をコンパクトに構成することができる。
更に、駆動回転体から駆動磁気車への動力伝達を請求項4記載の構成とした場合は、従来のような伝達に必要なベルト、チェーン等がないので、それらの制約を受けることなく搬送ローラを配置することができる。よって、メンテナンスフリーも勿論であるが、摩耗や発塵、接触による騒音の発生がない振り分けコンベヤを実現できる。
従って、本振り分けコンベヤを直線ローラコンベヤの間に配置し、該振り分けコンベヤの水平旋回の角度を調整することで、搬送物を複数方向(二方向、三方向等)に振り分けることができる。又、直角搬送路の交差部に本振り分けコンベヤを配置することで方向転換、及び搬送物の向きを転換して搬送するなど、幅広く活用することができる。
The sorting conveyor according to the present invention can provide a conveyor capable of handling a heavy load with a compact configuration without increasing the size of non-contact power transmission using magnetic force.
Further, according to the configurations of claims 3 to 5, the rotational force of a single drive rotating body can be efficiently transmitted to the two drive magnetic wheels, and the power transmission mechanism can be configured in a compact manner.
Further, when the power transmission from the drive rotating body to the drive magnetic wheel is configured as claimed in claim 4, there are no belts, chains, etc. necessary for transmission as in the prior art, so the conveying roller is not subject to these restrictions. Can be arranged. Therefore, it is possible to realize a sorting conveyor that is free from maintenance, but does not generate noise due to wear, dust generation, or contact.
Accordingly, by arranging the present distribution conveyor between the linear roller conveyors and adjusting the horizontal turning angle of the distribution conveyor, the conveyed product can be distributed in a plurality of directions (two directions, three directions, etc.). In addition, it can be widely used such as changing the direction by changing the direction of the conveyed object by conveying the sorting conveyor at the intersection of the right-angle conveying path.

以下、本発明に係る振り分けコンベヤの実施の一例を図面に基づいて説明する。
図1は、平面視略円形のフレーム内に複数本の搬送ローラを並列配置した振り分けコンベヤを示し、その振り分けコンベヤAは、フレームA1と、そのフレームA1内に取り付けた搬送ローラA2と、その搬送ローラA2を駆動回転する磁力を利用した非接触型の動力伝達機構A3と、前記フレームA1を水平旋回可能に支持する固定架台A4と、フレームA1を水平旋回する回転機構A5とで構成されている。
Hereinafter, an example of the implementation of the sorting conveyor according to the present invention will be described with reference to the drawings.
FIG. 1 shows a sorting conveyor in which a plurality of conveying rollers are arranged in parallel in a substantially circular frame in plan view. The sorting conveyor A includes a frame A1, a conveying roller A2 attached in the frame A1, and its conveying A non-contact type power transmission mechanism A3 using a magnetic force for driving and rotating the roller A2, a fixed gantry A4 that supports the frame A1 so as to be horizontally rotatable, and a rotation mechanism A5 that horizontally rotates the frame A1. .

フレームA1は、金属材叉は合成樹脂材で平面視略円形の筒枠1に構成され、その筒枠1の内側に、搬送ローラA2を、該筒枠1の略中心を通る位置(直径線上)からそれと直交する筒枠1の周壁方向に向かって漸次ローラ長に変化をつけて並列に配列して搬送面が構成されている。
前記筒枠1は、搬送ローラを並列配置する開口2を開設した上板1aと、前記上板1aと外径を略同じくする下板1bと、前記上板1aと下板1bとを所定間隔をおいて連結する連結側板1cとで構成されている。
上板1aに開設する開口2は、その開口2の内部に並列配置する搬送ローラA2の外周面との間に余分な隙間が生じないように平面視略階段状に形成されている。
下板1bは、略円形の平板で、その略中心に搬送ローラを駆動回転する動力源の回転軸を挿通する通孔3が開設されている。
連結側板1cは、上板1aと下板1bとの間に、搬送ローラA2を駆動回転する動力伝達機構A3を収容する空間(高さ)を区画形成すると共に、搬送ローラA2の支軸を支持する軸受となるもので、金属平板を断面略コの字型に折り曲げて構成され、前記上板1aに開口2における搬送ローラA2の軸端が対応する位置に対峙して取り付けられる。
The frame A1 is formed of a metal material or a synthetic resin material into a substantially circular cylindrical frame 1 in a plan view. Inside the cylindrical frame 1, a conveyance roller A2 is disposed at a position (on the diameter line) passing through the approximate center of the cylindrical frame 1. ) To the circumferential wall direction of the cylindrical frame 1 orthogonal thereto, the length of the rollers is gradually changed and arranged in parallel to constitute the conveying surface.
The cylindrical frame 1 has a predetermined interval between an upper plate 1a having an opening 2 in which conveying rollers are arranged in parallel, a lower plate 1b having substantially the same outer diameter as the upper plate 1a, and the upper plate 1a and the lower plate 1b. It is comprised with the connection side board 1c connected after a gap.
The opening 2 opened in the upper plate 1a is formed in a substantially step shape in plan view so as not to generate an extra gap between the opening 2 and the outer peripheral surface of the conveying roller A2 arranged in parallel.
The lower plate 1b is a substantially circular flat plate, and a through hole 3 is formed at a substantially center of the lower plate 1b through which a rotation shaft of a power source that drives and rotates the transport roller is inserted.
The connecting side plate 1c defines a space (height) for accommodating the power transmission mechanism A3 that drives and rotates the transport roller A2 between the upper plate 1a and the lower plate 1b, and supports the support shaft of the transport roller A2. The metal plate is bent in a substantially U-shaped cross section, and is attached to the upper plate 1a so that the shaft end of the transport roller A2 in the opening 2 faces the corresponding position.

搬送ローラA2は、アルミニウム材,ステンレス材,或いは合成樹脂材等、非磁性体で円筒に形成した筒状体4の内部に永久磁石のリング5、5’を嵌合すると共に、接着剤等で該筒状体4の内面に接着固定し、筒状体4の軸方向の両側端部には軸受6が嵌着固定され、更にその両側の軸受6に亘って支軸7を嵌装して構成されており、筒状体4が支軸7を中心として回転自在となるように構成されている。   The transport roller A2 is made of a non-magnetic material such as an aluminum material, a stainless steel material, or a synthetic resin material. The cylindrical body 4 is bonded and fixed to the inner surface, and the bearings 6 are fitted and fixed to both end portions in the axial direction of the cylindrical body 4, and the support shaft 7 is fitted over the bearings 6 on both sides. The cylindrical body 4 is configured to be rotatable about the support shaft 7.

前記搬送ローラA2を構成する筒状体4内に嵌合固定する永久磁石のリング5、5’は、図5に示すように、N極とS極を螺旋状に着磁したもので、そのリングの内径は該筒状体4の軸芯に沿って挿通される支軸7の外径より大径とし、支軸7に対し非接触状態となるように構成されている。
そして、各搬送ローラA2の筒状体4内に内蔵する永久磁石のリング5、5’は、搬送ローラA2をフレームA1の筒枠1に架設した時、各搬送ローラA2に装着した複数個(図面では2個)の永久磁石のリング5、5’がそれぞれ平行な2本の直線上に位置するように配置する。
The permanent magnet rings 5 and 5 'fitted and fixed in the cylindrical body 4 constituting the transport roller A2 are formed by spirally magnetizing the N pole and the S pole as shown in FIG. The inner diameter of the ring is larger than the outer diameter of the support shaft 7 inserted along the axis of the cylindrical body 4, and is configured to be in a non-contact state with respect to the support shaft 7.
A plurality of permanent magnet rings 5 and 5 ′ built in the cylindrical body 4 of each conveyance roller A 2 are attached to each conveyance roller A 2 when the conveyance roller A 2 is installed on the cylinder frame 1 of the frame A 1 ( The two permanent magnet rings 5, 5 ′ are arranged on two parallel lines.

即ち、各搬送ローラA2に内蔵する2個の永久磁石のリング5、5’は、搬送ローラA2の軸方向の中心位置から両軸端方向に同じ寸法離れた位置(対称位置)に配置する。それにより、各搬送ローラA2に内蔵される一方の永久磁石のリング5は仮想直線L1上に、他方の永久磁石5’は仮想直線L2上に並ぶことになる。   That is, the two permanent magnet rings 5 and 5 ′ built in each transport roller A 2 are arranged at positions (symmetric positions) that are separated from the center position in the axial direction of the transport roller A 2 by the same dimension in both end directions. Thereby, one permanent magnet ring 5 built in each conveyance roller A2 is arranged on the virtual straight line L1, and the other permanent magnet 5 'is arranged on the virtual straight line L2.

上記搬送ローラA2を前記フレームA1の筒枠1に対する軸支は、該搬送ローラA2における支軸7の軸端の一方を、筒枠1を構成する連結側板1cに対して回り止めして架設固定するよう、軸の外周面の一部叉は対向する二面を摺り割りなどして非円形に形成し、それにより筒枠1の連結側板1cに回り止めして取り付け、且つ連結側板1cより外方に突出する軸部に軸芯と直交してピン23を差し込んで抜止固定されている。これにより、搬送ローラA2は、永久磁石のリング5、5’を固着した筒状体4が支軸7を中心として回転自在となる。   The shaft of the transport roller A2 with respect to the cylindrical frame 1 of the frame A1 is fixed by suspending one of the shaft ends of the support shaft 7 of the transport roller A2 with respect to the connecting side plate 1c constituting the cylindrical frame 1. Thus, a part of the outer peripheral surface of the shaft or two opposing surfaces are formed in a non-circular shape by cutting, etc., so that they are attached to the connecting side plate 1c of the cylindrical frame 1 by being prevented from rotating, and outside the connecting side plate 1c. A pin 23 is inserted into a shaft portion projecting in the direction perpendicular to the shaft core and fixed to the shaft portion. As a result, in the transport roller A2, the cylindrical body 4 to which the permanent magnet rings 5, 5 'are fixed is rotatable about the support shaft 7.

上記搬送ローラA2を駆動回転させる動力伝達機構A3は、各搬送ローラA2に内蔵した永久磁石のリング5が並ぶ仮想直線L1と、永久磁石のリング5’が並ぶ仮想直線L2の位置に、該搬送ローラA2の外周面と非接触状態で且つ略直交状に交差させて回転自在に配置した2本の駆動磁気車8、8’と、その駆動磁気車8、8’へ駆動用モータ9の回転を伝達する磁気利用の非接触の動力伝達手段10とで構成されている。   The power transmission mechanism A3 for driving and rotating the transport roller A2 is arranged so that the transport is performed at the position of the virtual straight line L1 in which the permanent magnet rings 5 are arranged in the transport rollers A2 and the virtual straight line L2 in which the permanent magnet rings 5 ′ are aligned. Two drive magnetic wheels 8 and 8 'which are arranged in a non-contact state and substantially orthogonally intersecting with the outer peripheral surface of the roller A2, and the drive motor 9 is rotated to the drive magnetic wheels 8 and 8'. It is comprised with the non-contact power transmission means 10 of the magnetic utilization which transmits.

前記駆動磁気車8、8’は、前記搬送ローラA2の並設によって構成される搬送方向の長さと略同じ長さを有した軸8aの外側に、永久磁石で短筒状に形成した磁気車8bを軸方向に所定の間隔をおいて複数個嵌合固定して構成されている。
軸8aに嵌合固定する磁気車8bは、外周面にN極とS極が螺旋状に着磁されて構成されており、磁極とピッチは対向配置される前記搬送ローラA2に内蔵した永久磁石のリング5又は5’の磁極とピッチに対応して設定する。
又、軸8aに対する短筒状の磁気車8bの取付間隔は、前記搬送ローラA2の並設間隔によって決定され、それにより駆動磁気車8、8’の磁気車8bが、並設された全ての搬送ローラA2の永久磁石のリング5又は5’と対応するように構成されている。
The drive magnetic wheels 8 and 8 'are magnetic wheels formed in a short cylindrical shape with permanent magnets on the outside of a shaft 8a having a length substantially the same as the length in the transport direction constituted by the parallel arrangement of the transport rollers A2. A plurality of 8b are fitted and fixed at predetermined intervals in the axial direction.
The magnetic wheel 8b fitted and fixed to the shaft 8a is configured by helically magnetizing the N pole and the S pole on the outer peripheral surface, and the permanent magnet built in the transport roller A2 arranged to face the magnetic pole. It is set corresponding to the magnetic pole and pitch of the ring 5 or 5 '.
Further, the mounting interval of the short cylindrical magnetic wheel 8b with respect to the shaft 8a is determined by the parallel interval of the conveying roller A2, and accordingly, the magnetic wheels 8b of the driving magnetic wheels 8 and 8 'are all aligned. It is configured to correspond to the ring 5 or 5 'of the permanent magnet of the transport roller A2.

又、軸8aの外周面に軸方向に沿って磁気車8bを固着した駆動磁気車8と8’は、前記フレームA1における筒枠1の下板1b上に起立固定した取付片11’に軸受ユニット11を介して回転自在に支持されている。そして、その駆動磁気車8と8’は、下板1bに開設した通孔3を挟む位置で、且つ搬送ローラA2の軸芯と略直交する位置に配置される。
それにより、前記通孔3を貫通して配置される駆動用モータ9の回転を、動力伝達手段10を介して前記駆動磁気車8、8’に伝達するように構成されている。
Further, the drive magnetic wheels 8 and 8 ', in which the magnetic wheel 8b is fixed to the outer peripheral surface of the shaft 8a along the axial direction, are supported by a mounting piece 11' which is fixed upright on the lower plate 1b of the cylindrical frame 1 in the frame A1. The unit 11 is rotatably supported. The drive magnetic wheels 8 and 8 'are arranged at a position sandwiching the through hole 3 formed in the lower plate 1b and at a position substantially orthogonal to the axis of the transport roller A2.
Thereby, the rotation of the drive motor 9 disposed through the through hole 3 is transmitted to the drive magnetic wheels 8 and 8 ′ via the power transmission means 10.

Intermediate transmission magnetic wheels 10b, 10c, 10b ', 10c' are configured to transmit the rotation of the magnetic wheel 10a to the both driving magnetic wheels 8, 8 '. The intermediate transmission magnetic wheels 10b, 10b' are the original driving magnetic wheels 10a. The intermediate transmission magnetic wheels 10c and 10c ′ are fitted and fixed to the shaft 8a constituting the drive magnetic wheels 8 and 8 ′. Power transmission by non-contact magnetic force is possible between the original drive magnetic wheel 10a and the intermediate transmission magnetic wheels 10b and 10b ′, and between the intermediate transmission magnetic wheels 10b and 10b ′ and the intermediate transmission magnetic wheels 10c and 10c ′. A small gap is provided.
Accordingly, the rotation of the original drive magnetic wheel 10a is determined by the intermediate transmission magnetic wheel 10b → the intermediate transmission magnetic wheel 10c → the shaft 8a → the drive magnetic wheel 8 and the intermediate transmission magnetic wheel 10b ′ → the intermediate transmission magnetic wheel 10c ′ → the shaft 8a → It is transmitted to the drive magnetic wheel 8 ′.

動力伝達手段10を構成する元駆動磁気車10a、中間伝達磁気車10b,10b’、10c,10c’は、前記駆動磁気車8,8’の磁気車8bと同様、永久磁石で短筒状に構成され、その外周面にN極とS極が螺旋状に着磁されて構成されている。   The original drive magnetic wheel 10a and the intermediate transmission magnetic wheels 10b, 10b ′, 10c, 10c ′ constituting the power transmission means 10 are in the form of a short cylinder with permanent magnets, like the magnetic wheel 8b of the drive magnetic wheel 8, 8 ′.

上記構成により、元駆動磁気車10aが駆動用モータ9で回転されると、元駆動磁気車10aは中間伝達磁気車10b,10b’、及び中間伝達磁気車10c,10c’を介して2本の駆動磁気車8,8’へ回転を伝達し、その駆動磁気車8,8’の回転でフレームA1の筒枠1内に取り付けられた搬送ローラA2がそれぞれ駆動回転される。そして、搬送ローラA2の駆動回転により、被搬送物を搬送ローラA2の軸芯と直交する方向に搬送することができるが、フレームA1を水平旋回させることで搬送方向(搬送ローラの軸芯と直交する方向)を自由に変更することができる。
以下、その回転機構A5について説明する。
The frame A1 having the conveying roller A2 arranged in parallel and the power transmission means 10 for driving the conveying roller A2 therein is installed in the fixed base A4 so that the conveying surface constituted by the conveying roller A2 is horizontal.

In addition, the fixed base A4 is provided with a leg seat 35 whose height can be adjusted at the lower portion so that it can be installed at a level.
With the above configuration, when the original drive magnetic wheel 10a is rotated by the drive motor 9, the original drive magnetic wheel 10a is separated into two via the intermediate transmission magnetic wheels 10b and 10b ′ and the intermediate transmission magnetic wheels 10c and 10c ′. The rotation is transmitted to the drive magnetic wheels 8 and 8 ′, and the rotation of the drive magnetic wheels 8 and 8 ′ drives and rotates the transport rollers A2 attached in the cylindrical frame 1 of the frame A1. The transported object can be transported in a direction orthogonal to the axis of the transport roller A2 by driving rotation of the transport roller A2, but the transport direction (perpendicular to the axis of the transport roller) can be achieved by horizontally turning the frame A1. Direction) can be freely changed.
Hereinafter, the rotation mechanism A5 will be described.

回転機構A5は、図2に示すように、前記固定架台A4に固着した水平旋回用の駆動用モータ(サーボモータ)16と、その出力を減速する減速機17と、該減速機17の出力軸に固着したタイミングプーリ18と、前記フレームA1に固着された中空回転軸15に固着したタイミングプーリ19と、前記タイミングプーリ18とタイミングプーリ19とに亘って巻回したタイミングベルト20とで構成されている。これにより、駆動用モータ16の出力が減速機で減速され、その減速された回転力はタイミングプーリ18からタイミングプーリ19にタイミングベルト20を介して伝達され、フレームA1が水平旋回する。   As shown in FIG. 2, the rotation mechanism A5 includes a horizontal turning drive motor (servomotor) 16 fixed to the fixed base A4, a reduction gear 17 for reducing the output thereof, and an output shaft of the reduction gear 17.

A sensor 22a and overrun sensors 22b and 22c are installed, and thereby the angle control of the horizontal turning is performed. It should be noted that the arrangement of the flag and the sensor is not limited to the illustrated form, and can be appropriately performed such as changing the arrangement form in order to prevent interference between the sensors. The turning angle of the frame A1 may be controlled by an encoder.

又、上記フレームA1を囲む固定架台A4の上面には、前記フレームA1に取り付けた搬送ローラA2による搬送面と面一にフリーローラ24が配置されている。これにより、本振り分けコンベヤAに接続配置したローラコンベヤ等への乗り移り時、振り分けコンベヤAの搬送面と接続したローラコンベヤの搬送面との間にフリーローラ24が存在することで、被搬送物を水平に支持し、被搬送物が傾くのを防止できる。   A free roller 24 is arranged on the upper surface of the fixed base A4 surrounding the frame A1 so as to be flush with the conveying surface of the conveying roller A2 attached to the frame A1. As a result, when transferring to a roller conveyor or the like connected to the main distribution conveyor A, the free roller 24 exists between the conveyance surface of the distribution conveyor A and the conveyance surface of the roller conveyor connected thereto, thereby It can be supported horizontally to prevent the conveyed object from tilting.
