Description

本発明は、コンベヤの始端側に整列して搬入されたワークをコンベヤの終端側に向けて搬送しながら、該ワークを終端側における幅方向に沿った複数個所に仕分ける、或いはコンベヤの始端側に幅方向複数列から搬入されるワークをコンベヤの終端側に向けて搬送しながら、該ワークを終端側における幅方向の一箇所に合流させる仕分けコンベヤに係り、更に詳しくはベルトコンベヤタイプの仕分けコンベヤに関する。   The present invention sorts the workpieces arranged in a line at the start side of the conveyor toward a terminal end side of the conveyor while sorting the workpieces at a plurality of locations along the width direction on the terminal end side, or at the start end side of the conveyor. The present invention relates to a sorting conveyor that transports workpieces loaded from a plurality of rows in the width direction toward the end side of the conveyor and joins the workpieces to one place in the width direction on the end side, and more particularly to a belt conveyor type sorting conveyor. .

ワークをコンベヤ始端部から終端部に向けて搬送しながら、前記ワークを終端部においてコンベヤ搬送路の幅方向に沿って複数個所、例えば、左側、中央、右側の３箇所に仕分ける仕分けコンベヤとして特許文献１が提案されている。   Patent document as a sorting conveyor that sorts the workpieces into multiple locations along the width of the conveyor transport path, for example, left side, center, and right side, while conveying the workpieces from the conveyor starting end to the terminal end 1 has been proposed.

特許文献１に記載のものは、無端回動する一対のチェーン間に平行棒が横架され、その平行棒に物品搬送板（スラット）が摺動可能に取り付けられ、更に該物品搬送板の下面に突出棒が突出形成され、その突出棒は、前記チェーンの回動方向始端側から終端側に向けて搬送路の幅方向を１箇所（中央）から３箇所（左側、中央、右側）に仕分ける上側ガイドレールと下側ガイドレールと係合して、前記物品搬送板が平行棒に沿って左右方向に摺動するように構成されている。そして、コンベヤの始端部に搬入されたワークは複数本の物品搬送板に亘って載り、チェーンの無端回動により搬送される。   In the device described in Patent Document 1, a parallel bar is horizontally mounted between a pair of endlessly rotating chains, and an article conveying plate (slat) is slidably attached to the parallel bar, and further protrudes from the lower surface of the article conveying plate. A bar is formed in a protruding manner, and the protruding bar separates the width direction of the conveyance path from one place (center) to three places (left side, center, right side) from the start side to the end side in the rotational direction of the chain. The article conveying plate is configured to slide in the left-right direction along the parallel bars by engaging with the rail and the lower guide rail. And the workpiece | work carried in to the start end part of a conveyor is mounted over several articles | goods conveyance board, and is conveyed by the endless rotation of a chain.

しかし、上記スラット搬送方式のコンベヤはチェーンの無端回動によって搬送する為、始端部及び終端部にはチェーンスプロケットが配置され、この両チェーンスプロケットに亘ってチェーンが掛け回されている。その為に、コンベヤの始端部及び終端部における折り返し部材の径は大きくなり、該コンベヤ上流側又は下流側に連設配置するコンベヤや装置等との間隔（乗り移り間隔）が広くなるという問題点を有する。乗り移り間隔が広くなれば、小さいサイズのワークは、前記間隔（隙間）に落下するという危険も生じ、その為に落下を防止する棒等を前記間隔内に配置するなどの補助設備が必要となる、或いは該コンベヤで仕分け搬送できるワークのサイズが限定される等の不具合が生じる。更に、コンベヤはチェーンスプロケットとチェーンの噛合によって走行する為、チェーンスプロケットとチェーンの摩擦音による騒音が発生し、作業環境の改善が求められている。   However, since the conveyor of the slat transport system is transported by endless rotation of the chain, chain sprockets are arranged at the start and end portions, and the chain is wound around both the chain sprockets. For this reason, the diameter of the folding member at the beginning and end of the conveyor is increased, and the distance (transfer interval) between the conveyor and the device arranged continuously on the upstream side or downstream side of the conveyor is increased. Have. If the transfer interval becomes wide, there is a risk that a small-sized work will fall into the interval (gap), and therefore, auxiliary equipment such as arranging a rod or the like for preventing the fall within the interval is required. Alternatively, there is a problem that the size of the work that can be sorted and conveyed by the conveyor is limited. Furthermore, since the conveyor runs by meshing the chain sprocket and the chain, noise is generated due to frictional noise between the chain sprocket and the chain, and improvement of the working environment is required.

又、ワークは複数本の物品搬送板（スラット）に亘って載り、その複数本の物品搬送板はチェーンの回動によって回動方向に移動しながらガイドレールによって順次幅方向に移動され、それによりワークが仕分けられる。しかし、ワークを載せる複数本の物品搬送板が平行棒に沿って軸方向に水平移動する時、ワークを一緒に移動させる。
即ち、ワークを載せた複数本の物品搬送板は、ワークが載った投入時は各物品搬送板の幅方向が揃った平面視略矩形を維持するが、ガイドレールによって強制的に幅方向に移動される仕分け過程では平面視略菱形（平行四辺形）に変形する。
その結果、ガイドレールによって平面視略階段状に横移動された物品搬送板の上に載るワークは、姿勢が傾いた状態で仕分け排出される。この姿勢の傾きは、特に小型軽量のワークに生じやすい。
そして、搬入時の姿勢に対し、仕分け排出時の姿勢が変わった場合、仕分け後の次の処理作業によっては、再度搬入時の姿勢に戻すなどの作業が必要になる場合もある。
従って、出来るだけ搬入時の姿勢のままで仕分け排出されるのが好ましい。 The workpiece is placed on a plurality of article conveying plates (slats), and the plurality of article conveying plates are sequentially moved in the width direction by the guide rail while moving in the rotating direction by the rotation of the chain. Work is sorted. However, when the plurality of article transport plates on which the workpiece is placed horizontally moves in the axial direction along the parallel bars, the workpiece is moved together.
That is, the plurality of article transport plates on which the workpieces are placed maintain a substantially rectangular shape in plan view in which the width direction of each article transport plate is aligned when the workpieces are loaded, but are forcibly moved in the width direction by the guide rails. In the sorting process, it is deformed into a substantially rhombus (parallelogram) in plan view.
As a result, the workpieces placed on the article transport plate that has been laterally moved by the guide rails in a substantially staircase pattern in plan view are sorted and discharged in a state where the posture is inclined. This inclination of the posture tends to occur particularly in a small and light workpiece.
If the posture at the time of sorting and discharging changes with respect to the posture at the time of carry-in, depending on the next processing operation after sorting, a work such as returning to the posture at the time of carry-in may be required again.
Therefore, it is preferable to sort and discharge as much as possible while keeping the posture at the time of loading.

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、その目的とするところは、コンベヤの搬入及び搬出両側での折り返し部の径が小さく、ワークの搬入及び仕分け搬出の乗り移りが安定し、更に搬入時の姿勢と仕分け搬出時の姿勢が変化しない仕分けコンベヤを提供する。又、騒音の発生を軽減する仕分けコンベヤを提供する。   The present invention has been made in view of the above-described problems of the prior art. The object of the present invention is to change the diameter of the folded portion on both the carry-in and carry-out sides of the conveyor, and transfer of the work carry-in and sort-out. And a sorting conveyor in which the posture at the time of carrying in and the posture at the time of carrying out sorting do not change. Also, a sorting conveyor that reduces noise generation is provided.

上記目的を達成する為に本発明の仕分けコンベヤは、ワークを搬送するコンベヤをベルトコンベヤとし、更にそのベルトコンベヤの搬送面上に、ワークを載承して該ベルトの幅方向にスライドするワーク支持部材を配置すると共に、前記ワーク支持部材を単一部材で構成したことを特徴とする。
本発明で言う「仕分け」とは、コンベヤの始端側にワークが搬入され、そのワークを終端側に向かって搬送しながら終端部でベルト幅方向の複数の仕分け方向に分岐仕分けるタイプと、コンベヤの始端側にワークがベルト幅方向の複数列から搬入され、その複数列のワークを終端側に向かって搬送しながら終端部で整列合流させるタイプの両方を含むものとする。
又、上記分岐仕分けタイプの場合の始端側におけるワークの搬入は、幅方向１箇所に限らず、複数個所（複数列）でもよく、複数個所の場合は各列のワークを分岐仕分ける。同様に、合流タイプの場合も、終端部において整列合流させる箇所は、幅方向１箇所とは限らず、少なくとも搬入時の列数より少ない数列に整列合流させる形態も含んでいる。 In order to achieve the above object, the sorting conveyor according to the present invention uses a belt conveyor as a conveyor for conveying workpieces, and further supports a workpiece supported on the conveying surface of the belt conveyor and slid in the width direction of the belt. A member is arranged, and the workpiece support member is constituted by a single member.
The “sorting” as used in the present invention refers to a type in which a work is loaded into the start end side of the conveyor and the work is transported toward the end side, and is branched and sorted in a plurality of sorting directions in the belt width direction at the end portion. It includes both types in which workpieces are carried in from the plurality of rows in the belt width direction to the starting end side, and the plurality of rows of workpieces are aligned and joined at the end portion while being conveyed toward the end side.
In the case of the above-mentioned branch sorting type, the work loading on the starting end side is not limited to one place in the width direction, and may be carried out at a plurality of places (a plurality of rows). Similarly, in the case of the merging type, the position where the merging is performed at the end portion is not limited to one position in the width direction, and includes a form where the merging is performed at least in several rows less than the number of rows at the time of loading.

即ち、フレームの機長方向両側に配置した折り返し部材に亘って無端状の搬送用ベルトを掛け回し、その搬送用ベルトの外表面に、ワークを載承支持するワーク支持部材を前記搬送用ベルトの回動方向と交差する方向にスライド可能に取り付け、更に、ベルトの往路側において前記ワーク支持部材を、搬送路の始端部側における幅方向の原点位置から終端部側の幅方向の仕分け位置に向けて仕分け案内する仕分け案内手段と、ベルトの復路側において幅方向に仕分けられたワーク支持部材を始端部の原点位置に案内復帰させる原点復帰案内手段を配置し、搬送用ベルトの回動によりワーク支持部材を回動方向始端部から終端部に移動させながら前記仕分け案内手段によって仕分け位置に向けて移動させ、ワークを仕分け搬出後は始端部に移動しながら原点位置に復帰させることを特徴とする（請求項１）。
前記フレームに架設する折り返し部材としては、ベルトコンベヤにおいて一般的に用いられているローラ（テールローラ）、平板（ナイフエッジ）等が挙げられる。
前記折り返し部材に亘って掛け回す搬送用ベルトとしては、今日一般的に使用されている樹脂製ベルト、ゴム製ベルト、或いはプラスチックモジュールベルト等が挙げられる。 That is, an endless conveying belt is hung over the folding members disposed on both sides in the machine length direction of the frame, and a work supporting member for supporting the work is placed on the outer surface of the conveying belt. The workpiece support member is slidably mounted in a direction crossing the moving direction, and further, the work support member is moved toward the sorting position in the width direction on the end side from the origin position in the width direction on the start end side of the conveyance path. Sorting guidance means for sorting guidance and origin return guiding means for guiding and returning the workpiece support member sorted in the width direction on the return path side of the belt to the origin position of the start end are arranged, and the workpiece support member is rotated by rotating the conveying belt Is moved toward the sorting position by the sorting guidance means while moving the workpiece from the start end to the end in the rotation direction, and the workpiece is moved to the start end after carrying out sorting. While wherein the to return to the origin position (claim 1).
Examples of the folding member provided on the frame include a roller (tail roller), a flat plate (knife edge) and the like generally used in a belt conveyor.
Examples of the conveying belt that wraps around the folded member include a resin belt, a rubber belt, or a plastic module belt that are generally used today.

前記ワーク支持部材は、搬送用ベルトの回動と一緒に回動し得るよう屈曲可撓性を有した部材、例えば、合成樹脂製シート、布地、網地、プラスチックモジュールベルト等で構成され、その形態は一枚もの、或いは複数の片を連結して一枚もの様に形成したもの等、何れでもよい。
そして、前記ワーク支持部材は、屈曲可能なシート片で、そのシート片の少なくとも搬送方向前側を前記搬送用ベルトにスライド手段を介してスライド可能に支持する（請求項２）。
前記スライド手段は、搬送用ベルトの外表面に回動方向と直交状に固着したガイドと、そのガイドに対してスライド可能に係合するワーク支持部材に固着したスライダーで構成されている（請求項３）。
前記ガイドとスライダーの形態は、スライダーがガイドに沿ってスライドする構成であればよく、例えば、スライドファスナーの形態、雄部材（凸部材）と雌部材（凹部材）の噛み合い形態等が挙げられ、スライダーはガイドに対して着脱可能になっている。 The workpiece support member is composed of a member having bending flexibility so as to be able to rotate together with the rotation of the conveying belt, for example, a synthetic resin sheet, fabric, netting, plastic module belt, etc. The form may be any one, or a single piece formed by connecting a plurality of pieces.
The workpiece support member is a bendable sheet piece, and at least the front side in the conveyance direction of the sheet piece is slidably supported by the conveyance belt via a slide unit.
The slide means is composed of a guide fixed to the outer surface of the conveying belt in a direction orthogonal to the rotation direction, and a slider fixed to a work support member that slidably engages with the guide (claim). 3).
The form of the guide and the slider may be any structure as long as the slider slides along the guide, for example, the form of a slide fastener, the engagement form of a male member (convex member) and a female member (concave material), etc. The slider is detachable from the guide.

上記手段によれば、コンベヤの始端部側の原点位置においてワーク支持部材にワークが載ると、該ワーク支持部材はワークを載せたまま搬送用ベルトの回動によって終端部側に向けて一緒に移動する。そして、ワーク支持部材は搬送用ベルトに対して該ベルトの回動方向と交差する方向にスライド可能に取り付けられ、且つ、原点位置から終端部側の幅方向の仕分け位置に向けて仕分け案内する仕分け案内手段との作用により、前記ワーク支持部材は終端部に向けて移動しながら案内手段によって横移動（幅方向に移動）され、仕分け位置に移動される。しかも、前記ワーク支持部材の横移動は、一体化したワーク支持部材全体が水平移動する為、ワーク支持部材に載承されたワークの姿勢は、ワーク支持部材に載った時の姿勢のままで仕分け位置に搬送され、そのまま搬出される。即ち、ワークを搬入時と搬出時の姿勢を変化させずに仕分け搬送することができる。そして、ワーク支持部材を取り付けたスライダーはガイドに対して着脱可能であるため、ワーク支持部材を含めたスライダーのメンテナンスを容易に行うことができる。   According to the above means, when a workpiece is placed on the workpiece support member at the origin position on the start end side of the conveyor, the workpiece support member moves together toward the end portion side by rotation of the conveying belt while the workpiece is placed. To do. The work support member is slidably attached to the transport belt in a direction crossing the rotation direction of the belt, and sorts and guides the work support member from the origin position to the sort position in the width direction on the terminal end side. By the action with the guide means, the work support member is moved laterally (moved in the width direction) by the guide means while moving toward the terminal portion, and is moved to the sorting position. In addition, the lateral movement of the workpiece support member causes the entire workpiece support member to move horizontally, so that the posture of the workpiece placed on the workpiece support member remains the same as the posture on the workpiece support member. It is transported to the position and unloaded as it is. That is, the workpieces can be sorted and conveyed without changing the posture at the time of loading and unloading. And since the slider to which the work supporting member is attached is detachable from the guide, maintenance of the slider including the work supporting member can be easily performed.

前記仕分け案内手段及び原点復帰案内手段としては、例えば、磁石の吸着作用を用いた方式、機械的なガイド方式等が挙げられる。
磁石を用いた吸着方式の具体例は、前記ワーク支持部材のスライダーに固着した磁石若しくは磁性体と、前記搬送用ベルトの往路側と復路側の間に配置したトラフに固着配設した磁石若しくは磁性体とからなり、磁石の吸着作用によりワーク支持部材が搬送用ベルトの回動により該ベルトの幅方向の仕分け位置に横移動、及び原点位置に横移動するようにする（請求項４）。
前記トラフは、搬送用ベルトの往路側、復路側と接近対応させて上下に配置される。
スライダー及びトラフに固着する磁石若しくは磁性体は、両者が吸着作用を生じるものであればよく、例えば、一方をＮ極の磁石、他方をＳ極の磁石とする。或いは、一方を磁石、他方を磁石と吸着する金属板とする。 Examples of the sorting guide means and the origin return guide means include a method using a magnet attracting action and a mechanical guide method.
Specific examples of the adsorption method using magnets include a magnet or magnetic material fixed to the slider of the work support member, and a magnet or magnetic fixedly disposed on a trough disposed between the forward path side and the return path side of the conveyance belt. The workpiece supporting member is moved laterally to the sorting position in the width direction of the belt and moved to the origin position by the rotation of the conveying belt by the attracting action of the magnet.
The troughs are arranged up and down in close proximity to the forward side and the return side of the conveyance belt.
The magnet or the magnetic body fixed to the slider and the trough may be any one that causes an adsorption action. For example, one is an N-pole magnet and the other is an S-pole magnet. Alternatively, one is a magnet and the other is a metal plate that adsorbs the magnet.

上記仕分け案内手段は、搬送用ベルトの往路側と対向するトラフの表面側に、前記搬送用ベルトの回動方向始端側から終端側に向かって磁石を配設した分岐仕分け又は合流仕分けの仕分け軌条と、該仕分け軌条が分岐仕分けである場合、その仕分け軌条の手前側に配置した磁石で構成した仕分け切替軌条とで構成する。又、原点復帰案内手段は、搬送用ベルトの復路側と対向するトラフの表面側に、前記搬送用ベルトの回動方向終端側から始端側に向かって磁石を配設した原点復帰軌条と、前記仕分け軌条が合流仕分けである場合、前記原点復帰軌条の手前側に配置した磁石で構成した仕分け切替軌条とで構成する（請求項５）。
上記仕分け軌条の配設本数は、複数本（二本以上）で、例えば三本であれば左側，中央，右側、四本であれば左外，左中，右中，右外等とする。
又、仕分け軌条と仕分け切替軌条とからなる仕分け案内手段は、トラフの表面に一組だけ配設する形態に限定されず、複数組配設してもよい。例えば、回動方向始端側から中程位置まで三分岐とし、その三分岐の左側と右側を更に仕分け切替軌条と仕分け軌条によって二本に分岐させ、回動方向終端側において最終的に五本分岐（左外，左中，真中，右中，右外）とする等、任意である。
原点復帰案内手段は、終端側で仕分けたワーク支持部材を始端側の原点位置（幅方向の略中央位置）に戻すもので、三分岐であれば左側と右側を原点位置に案内するよう平面視略ハ字型に配置される。分岐路の中央位置に仕分けられたワーク支持部材は、仕分けられえた時の位置に保持されたまま搬送用ベルトの回動で原点位置に復帰する為、不要である。 The sorting guide means is a branching or merging sorting rail in which magnets are arranged on the surface side of the trough facing the forward side of the transport belt from the start end side to the end side in the rotational direction of the transport belt. And when this sort rail is a branch sort, it comprises with the sort change rail constituted with the magnet arranged on the near side of the sort rail. In addition, the origin return guide means includes an origin return rail in which a magnet is disposed on the surface side of the trough facing the return path side of the conveyor belt from the rotation direction end side to the start end side of the conveyor belt, When the sorting rail is a merging sorting, the sorting rail is constituted by a sorting switching rail constituted by a magnet arranged on the front side of the origin return rail (Claim 5).
The number of the above-mentioned sorting rails is a plurality (two or more). For example, three are left side, center, right side, four are left outside, left middle, right middle, right outside, etc.
In addition, the sorting guide means including the sorting rail and the sorting switching rail is not limited to a mode in which only one set is provided on the surface of the trough, and a plurality of sets may be provided. For example, there are three branches from the start side in the rotation direction to the middle position, and the left and right sides of the three branches are further branched into two by the sorting switching rail and the sorting rail, and finally five branches at the end in the rotation direction (Outside left, left middle, middle, right middle, right outside) are optional.
The origin return guide means returns the workpiece support member sorted on the end side to the origin position (substantially the center position in the width direction) on the start end side, and in a plan view to guide the left and right sides to the origin position if there are three branches. It is arranged in a roughly C shape. The work supporting members sorted at the center position of the branch path are unnecessary because they are returned to the original position by the rotation of the conveying belt while being held at the sorted position.

そして、上記仕分け軌条及び仕分け切替軌条をＮ極の磁石を一列に配置して構成した場合は、ワーク支持部材のスライダーに固着する磁石はＳ極とする。勿論、その逆の形態でもよい。或いは、トラフに磁石を配列し、スライダーには前記磁石と吸着作用を生じる金属板を固着してもよい。   When the sorting rail and the sorting switching rail are configured by arranging N-pole magnets in a line, the magnet fixed to the slider of the workpiece support member is the S pole. Of course, the reverse configuration may be used. Alternatively, magnets may be arranged in the trough, and a metal plate that generates an attracting action with the magnets may be fixed to the slider.

機械的なガイド方式の具体例としては、例えば、前記ワーク支持部材のスライダーに固着した案内ピンと、前記搬送用ベルトの往路側上方と復路側下方に配設した案内桟とからなり、前記案内ピンが前記案内桟に当接係合することでワーク支持部材が搬送用ベルトの回動により前記案内桟によって該ベルトの幅方向の仕分け方向、及び原点位置に横移動するように構成する（請求項６）。
前記案内ピンは、スライダーの上面に、長手方向中央位置から左右対称の位置に１本ずつ起立固定する形態、或いは長手方向の一方端部又は略中央位置に１本を起立固定する形態等、何れでもよい。
前記案内桟は、前記ワーク支持部材の案内ピンを搬送用ベルトの幅方向に案内するもので、「分岐仕分け」の場合の往路側は始端側から終端側に向かって末広がり状に配置し、その案内桟の外側面に前記案内ピンを当接させる、復路側は終端側から始端側に向かって先細り状に配置し、その案内桟の内側面に前記案内ピンを当接させる。
又、「合流」の場合は前記「分岐仕分け」の場合の逆、即ち、分岐仕分けタイプの復路側の形態を往路側に、往路側の形態を復路側に配置する。更に、前記案内ピンの取付形態（本数と位置）に応じて案内桟を設置する位置を適宜変更する。尚、案内ピンが１本の場合は、仕分けの方向によっては案内桟がワークの搬送に障害となる場合もあり、従って、案内桟は固定式でなく可動式とする。 Specific examples of the mechanical guide system include, for example, a guide pin fixed to a slider of the work support member, and guide bars disposed on the forward side and the return side of the conveyor belt. Is in contact with and engages with the guide bar, so that the work support member is moved laterally by the guide bar to the sorting direction in the width direction of the belt and the origin position by the rotation of the conveying belt. 6).
The guide pins stand upright and fixed to the upper surface of the slider one by one from the longitudinal center position to the left-right symmetrical position, or one of the guide pins stand upright and fixed at one end or approximately the center position in the longitudinal direction. But you can.
The guide bar guides the guide pin of the work support member in the width direction of the conveying belt. In the case of "branch sorting", the forward path side is arranged so as to widen from the start side to the end side, The guide pin is brought into contact with the outer surface of the guide bar, the return path side is tapered from the end side to the start side, and the guide pin is brought into contact with the inner side surface of the guide bar.
In the case of “joining”, the reverse of the “branch sorting” case, that is, the branch sorting type return path configuration is arranged on the forward path side, and the forward path configuration is arranged on the return path side. Furthermore, the position where the guide bar is installed is appropriately changed according to the mounting form (number and position) of the guide pins. If there is only one guide pin, the guide bar may obstruct the transfer of the workpiece depending on the sorting direction. Therefore, the guide bar is not fixed but movable.

前記仕分け案内手段は、搬送用ベルトの往路側表面と離間して該搬送用ベルトの回動方向始端側から終端側に向かって配設した分岐仕分け又は合流仕分けの仕分け用案内桟と、該仕分け用案内桟が分岐仕分けである場合、その仕分け用案内桟の手前側に配置した仕分け切替手段とから成り、原点復帰案内手段は、前記搬送用ベルトの復路側表面と離間して該搬送用ベルトの回動方向終端側から始端側に向かって配設した原点復帰用案内桟と、前記仕分け用案内桟が合流仕分けである場合、前記原点復帰用案内桟の手前側に配置した仕分け切替手段とで構成する（請求項７）。
そして、原点復帰案内手段は、「合流」タイプの場合、原点復帰用案内桟を終端側から始端側に向かって平面視略末広がり状に拡開配置するため、原点復帰用案内桟の手前（終端）側には仕分け切替手段を配置する。 The sorting guidance means includes a sorting guide for branch sorting or merging sorting arranged away from the surface on the forward path side of the conveyor belt and arranged from the start end side to the end end side in the rotational direction of the conveyor belt, When the guide rail is for branch sorting, it comprises sorting switching means arranged on the front side of the sorting guide rail, and the origin return guide means is separated from the return path surface of the conveyor belt and the conveyor belt When the origin return guide bar arranged from the end side to the start end side of the rotation direction and the sorting guide bar are merging sorting, sorting switching means arranged on the front side of the origin return guide bar; (Claim 7).
In the case of the “merging” type, the origin return guide means is arranged in such a manner that the origin return guide bar is widened from the terminal end side to the start end side so as to be substantially widened in the plan view. ) Side is provided with sorting switching means.

前記仕分け切替手段は、「分岐仕分け」の場合、ワーク毎に設定された仕分け情報を検出する検出センサと、その検出センサが検出したワークを載承するワーク支持部材を、前記検出信号に基づいて仕分け方向に移動する移動手段と、ワーク支持部材が所定位置を通過したことを検出して前記移動手段を作動させる制御手段とで構成され、搬送用ベルトの往路側に配置される。
又、「合流」の場合は、ワーク毎に設定された仕分け情報を検出する検出センサと、その検出センサが検出したワークを載承するワーク支持部材を、前記検出信号に基づいて原点位置に移動する移動手段と、ワーク支持部材が所定位置を通過したことを検出して前記移動手段を作動させる制御手段とで構成され、搬送用ベルトの復路側に配置される。
前記検出センサは、本仕分けコンベヤにワークを搬入する搬入コンベヤの終端寄り若しくは本仕分けコンベヤの搬入部に配置される。又、制御手段はワークの移動速度とワーク支持部材（搬送用ベルト）の移動速度によりタイミングを合わせて、ワーク支持部材にワークを載せる。 In the case of “branch sorting”, the sorting switching means includes a detection sensor for detecting sorting information set for each workpiece and a workpiece support member for mounting the workpiece detected by the detection sensor based on the detection signal. The moving means that moves in the sorting direction and the control means that detects that the work supporting member has passed a predetermined position and operates the moving means are arranged on the forward path side of the conveying belt.
In the case of “joining”, a detection sensor for detecting sorting information set for each workpiece and a workpiece support member for mounting the workpiece detected by the detection sensor are moved to the origin position based on the detection signal. And a control means for operating the moving means by detecting that the work supporting member has passed a predetermined position, and is disposed on the return path side of the conveying belt.
The detection sensor is arranged near the end of the carry-in conveyor that loads the work into the main sorting conveyor or in the carry-in portion of the main sorting conveyor. The control means places the work on the work support member in synchronism with the movement speed of the work and the movement speed of the work support member (conveying belt).

そして、仕分け切替軌条の水平揺動は、ワーク毎に設定された仕分け情報の検出信号に基づいて自動的に作動する自動切替えとする（請求項８）。それにより、効率よく仕分け作業を行うことができる。勿論、作業者がワークを見て手動でレバーやハンドルを操作して切り替える手動切替えとしてもよいものである。 The sorting switching rail and the sorting switching means are configured to switch the transition direction toward the branch sorting direction or the origin position of the workpiece support member according to the workpiece to be loaded, and open toward the branch sorting opening angle or the origin position. Swing horizontally within the corner range.
The horizontal swing of the sorting switching rail is automatically switched based on a sorting information detection signal set for each workpiece (claim 8). Thereby, the sorting operation can be performed efficiently. Of course, it is also possible to perform manual switching in which the operator manually switches the lever and handle while looking at the workpiece.

又、磁石を用いた吸着方式による「合流」タイプの仕分け案内手段及び原点復帰案内手段は、「分岐仕分け」タイプの原点復帰案内手段を仕分け案内手段に、「分岐仕分け」タイプの仕分け案内手段を原点復帰案内手段に置き換えた構成とする。即ち、「合流」タイプの場合は、原点復帰案内手段側に切替軌条を配置する。   In addition, the “joining” type sorting guidance means and the origin return guidance means by the magnet type attracting method are the “branch sorting” type origin return guidance means as the sorting guidance means, and the “branch sorting” type sorting guidance means. The home position return guide means is used. That is, in the case of the “merging” type, the switching rail is arranged on the origin return guide means side.

前記搬送用ベルトは、一般的なベルトコンベヤの摩擦駆動方式であるヘッドドライブ方式で駆動してもよいが、搬送用ベルトの幅方向の両側部、即ち、搬送用ベルトの表面側に配設するスライド手段より外側のベルト部分を利用し、該部分をベルトの上下に配置した駆動回転体で挟持して搬送する駆動方式としてもよい（請求項９）。その場合、機長方向両側の折り返し部材は、小径のローラ又はナイフエッジとする。本発明で言う小径とは、搬送用ベルトを折り返すために必要な最小プーリ径である。

A driving method may be employed in which a belt portion outside the sliding means is used, and the portion is sandwiched and transported by driving rotating bodies disposed above and below the belt. In this case, the folding members on both sides in the machine length direction are small diameter rollers or knife edges. The small diameter referred to in the present invention is the minimum pulley diameter necessary for folding the conveyor belt.
The installation position of the drive rotator that pinches and conveys the conveyance belt may be on either the forward path side or the return path side of the conveyance belt, but when taking into consideration the attachment / detachment of the conveyance belt or the use of the full width in the width direction Is more effective when installed on the return path side of the conveyor belt.

In addition, since the conveyor for transportation is constituted by a belt conveyor, the radius of the folded portion of the belt can be made smaller than the radius of the chain sprocket of the conventional slat conveyor, thereby connecting to the carry-in side and the carry-out side of the sorting conveyor. The gap between the conveyor and the apparatus can be reduced, the transfer can be performed stably, and a quiet sorting conveyor can be provided.

以下、本発明に係る仕分けコンベヤの実施の形態を図面に基づいて説明する。   Embodiments of a sorting conveyor according to the present invention will be described below with reference to the drawings.

図１乃至図１１は、ワーク支持部材を、搬送用ベルトの幅方向（搬送用ベルトの回動方向に対し直交する方向）にスライドさせる手段を、磁石の吸着作用を利用して行うように構成した実施例で、且つ分岐仕分けタイプの仕分けコンベヤである。
図１は仕分けコンベヤの平面図で、図中、１はコンベヤフレーム、２は前記コンベヤフレーム１に無端回動可能に掛け回した搬送用ベルト、３は前記搬送用ベルト２の外表面に該ベルトの幅方向にスライド可能に配置したワーク支持部材、４は前記ワーク支持部材３を前記搬送用ベルト２に対してスライド可能に支持するスライド手段、５は前記ワーク支持部材３を、搬送用ベルト２の始端側所定位置（ベルト幅方向の略中央位置）から終端側の幅方向における複数の仕分け位置に向けて仕分け案内する仕分け案内手段、６は前記複数の仕分け方向に仕分けられたワーク支持部材３を始端側の原点位置に案内復帰させる原点復帰案内手段、７は前記搬送用ベルト２を回動させる駆動手段である。 1 to 11 are configured so that the means for sliding the work supporting member in the width direction of the conveying belt (the direction perpendicular to the rotation direction of the conveying belt) is performed by using the attracting action of the magnet. In this embodiment, the sorting conveyor is of the branch sorting type.
FIG. 1 is a plan view of a sorting conveyor. In the figure, 1 is a conveyor frame, 2 is a conveyor belt wound around the conveyor frame 1 in an endlessly rotatable manner, and 3 is a belt on the outer surface of the conveyor belt 2. 4 is a slide means for slidably supporting the work support member 3 with respect to the transport belt 2, and 5 is a slide means for supporting the work support member 3 with respect to the transport belt 2. A sorting guide means for sorting and guiding a plurality of sorting positions in a width direction on the end side from a predetermined position on the leading end side (substantially the center position in the belt width direction), and a work support member 3 sorted in the plurality of sorting directions. An origin return guide means for guiding the guide to the origin position on the start end side, and 7 a drive means for rotating the conveyor belt 2.

前記コンベヤフレーム１は、所定の間隔をおいて対向配置した側枠１ａ，１ａ’の上端間に、搬送用ベルトの搬送面（往路面）を下側から支える上トラフ１ｂが一体に構成されており、その上トラフ１ｂの表面側（搬送用ベルト２の往路側と対向する面）に仕分け案内手段５が配置され、側枠１ａ，１ａ’の機長方向（長手方向）の両側部にはテールブラケット８を介してテールローラ（折り返し部材）９，９’が上下方向に段差を付けて回転可能に横架され、その両側のテールローラ９，９’、９，９’に亘って搬送用ベルト２が掛け回されている。
上記テールブラケット８の一方（図面では左側）はコンベヤフレーム１に対して起伏回動可能に取り付けられ、搬送用ベルト２をコンベヤフレーム１から取り外す時は該テールブラケット８を上方に回動して搬送用ベルト２に弛みを作り、ベルトの着脱を容易に行うことができるようにしてある。
又、機長方向両側のテールブラケット８，８に亘って下トラフ１ｂ’が水平に架設され、その下トラフ１ｂ’の下面（搬送用ベルトの復路面と対向する面）に原点復帰案内手段６が配置されている。
更に、前記側枠１ａ，１ａ’には脚部材１０が垂下固定されて、コンベヤフレーム１が所定の高さに支持されるように構成されている。
尚、上トラフ１ｂは、側枠１ａ，１ａ’と一体構造に限らず、側枠１ａ，１ａ’と別体で両者をボルト・ナット等で連結固定する構成としてもよい。 In the conveyor frame 1, an upper trough 1b is integrally formed between the upper ends of the side frames 1a and 1a 'opposed to each other at a predetermined interval to support the conveying surface (forward path surface) of the conveying belt from below. In addition, sorting guide means 5 is arranged on the surface side of the trough 1b (the surface facing the forward path side of the conveyor belt 2), and tails are provided on both sides in the machine length direction (longitudinal direction) of the side frames 1a and 1a '. Tail rollers (folding members) 9 and 9 ′ are horizontally mounted with a step in the vertical direction via the bracket 8, and can be rotated across the tail rollers 9, 9 ′, 9 and 9 ′ on both sides thereof. 2 is hung around.
One of the tail brackets 8 (the left side in the drawing) is attached to the conveyor frame 1 so as to be able to turn up and down, and when removing the conveyor belt 2 from the conveyor frame 1, the tail bracket 8 is rotated upward to convey it. The belt 2 is slack so that the belt can be easily attached and detached.
Further, a lower trough 1b 'is installed horizontally across the tail brackets 8 on both sides in the machine length direction, and origin return guide means 6 is provided on the lower surface of the lower trough 1b' (the surface facing the return path surface of the conveying belt). Is arranged.
Furthermore, leg members 10 are suspended and fixed to the side frames 1a and 1a 'so that the conveyor frame 1 is supported at a predetermined height.
The upper trough 1b is not limited to the one-piece structure with the side frames 1a and 1a ', and may be configured to be connected and fixed by bolts, nuts and the like separately from the side frames 1a and 1a'.

前記下トラフ１ｂ’は、上トラフ１ｂに比較して機長方向と直交する方向の寸法が幅狭く構成され、その下トラフ１ｂ’が幅方向の中央位置に配置固定されている。それにより、前記下トラフ１ｂ’の幅方向外側位置に、下トラフ１ｂ’の下面側を走行する搬送用ベルト２の復路側の側部を挟持して搬送する駆動手段７が配置されている。   The lower trough 1b 'has a narrower dimension in the direction perpendicular to the longitudinal direction than the upper trough 1b, and the lower trough 1b' is arranged and fixed at the center position in the width direction. As a result, driving means 7 is disposed at the outer side in the width direction of the lower trough 1b 'so as to sandwich and convey the side portion on the return path side of the conveying belt 2 traveling on the lower surface side of the lower trough 1b'.

搬送用ベルト２は、周方向及び周方向と直交する幅方向の伸びを抑制し、且つベルトの上下に配置される磁石同士の吸着作用を妨げない素材、例えば内部に芯材を埋設した合成樹脂製のベルトで、このベルトの外表面に、スライド手段４が周方向に一定の間隔をおいて平行に固着されている。そして、その各スライド手段４にワーク支持部材３がスライド可能に取り付けられている。尚、搬送用ベルト２は一般的な一枚もののベルトに限らず、プラスチックモジュールベルト等でもよい。   The conveying belt 2 is a material that suppresses the elongation in the circumferential direction and the width direction orthogonal to the circumferential direction and does not hinder the adsorption action between magnets arranged above and below the belt, for example, a synthetic resin in which a core material is embedded. A sliding belt 4 is fixed to the outer surface of the belt in parallel at a constant interval in the circumferential direction. The work support member 3 is slidably attached to each slide means 4. The conveying belt 2 is not limited to a general one, but may be a plastic module belt or the like.

前記スライド手段４は、スライド可能に噛み合うガイド４ａとスライダー４ｂとからなり、前記ガイド４ａは合成樹脂材によって棒状に構成されると共に、該ガイド４ａの長手方向に沿って前記搬送用ベルト２への取付片１１が一体に形成されている。尚、取付片１１は、ガイド４ａと別体の構造とし、縫着或いは接着等によって一体化してもよい。その場合、取付片１１の素材としては、合成樹脂製シート、或いは布地等、何れでもよい。
又、前記ガイド４ａにおける長手方向と直交する方向の幅は極力幅狭く形成し、フレーム両側のテールローラの外周面に沿って移動する時、搬送用ベルト２の搬送面から立ち上がらず、ワークＷがスムーズに乗り移るようにする。更に、ガイド４ａの長さは、搬送用ベルト２の幅方向における仕分け幅より多少長く形成し、ワーク支持部材が仕分け動作中にスライド手段から外れたりすることがないようにしてある。 The slide means 4 includes a guide 4a and a slider 4b that are slidably engaged with each other. The guide 4a is formed in a rod shape by a synthetic resin material, and is connected to the transport belt 2 along the longitudinal direction of the guide 4a. The attachment piece 11 is integrally formed. The attachment piece 11 may be a separate structure from the guide 4a and may be integrated by sewing or bonding. In that case, the material of the attachment piece 11 may be either a synthetic resin sheet or a fabric.
The width of the guide 4a in the direction perpendicular to the longitudinal direction is made as narrow as possible. When the guide 4a moves along the outer peripheral surface of the tail roller on both sides of the frame, it does not stand up from the conveying surface of the conveying belt 2 and the workpiece W Try to get on smoothly. Further, the length of the guide 4a is formed to be slightly longer than the sorting width in the width direction of the conveying belt 2, so that the work support member does not come off the slide means during the sorting operation.

上記ガイド４ａを備えた取付片１１は、搬送用ベルト２の外表面に該ベルトの周方向（回動方向）と直交させて略中央位置に配置固定されている。搬送用ベルト２に対する取付片１１の固定は、縫着或いは接着、熱溶着等何れでもよい。尚、ガイド４ａを搬送用ベルト２に固着する為の取付片１１は、図示するように搬送用ベルト２の回動方向に沿った前側のみが固着され、後側が開放された片支持構造に限らず、ガイド４ａの前後縁に取付片を取り付け、その前後の取付片を搬送用ベルト２に固定する両支持構造としてもよいものである。   The mounting piece 11 provided with the guide 4a is arranged and fixed at a substantially central position on the outer surface of the conveying belt 2 so as to be orthogonal to the circumferential direction (rotating direction) of the belt. The attachment piece 11 may be fixed to the conveyor belt 2 by any method such as sewing, adhesion, or heat welding. The attachment piece 11 for fixing the guide 4a to the transport belt 2 is limited to a single support structure in which only the front side along the rotation direction of the transport belt 2 is fixed and the rear side is opened as shown in the figure. Instead, it is good also as a both support structure which attaches an attachment piece to the front-and-rear edge of the guide 4a, and fixes the attachment piece before and behind that to the belt 2 for conveyance.

前記ガイド４ａと係合するスライダー４ｂは、ガイド４ａと同様、合成樹脂材或いは金属材によって短尺の棒状に構成され、ガイド４ａの長手方向の端部より嵌合装着し、ガイドの長手方向に沿ってスライド可能に構成されている。尚、スライダー４ｂをガイド４ａに対してスライド可能に装着する方法は、上記したガイド４ａの端部から嵌着する方法に限らず、ガイド４ａの長さの範囲内のどの位置からでも嵌着し得るように構成してもよい。
又、スライダー４ｂは、上面の一側部にワーク支持部材３を取り付け、且つ下面には凹部１２が切欠され、その凹部１２に仕分け案内手段５及び原点復帰案内手段６の構成部材の一方である磁石(磁性体)１３が該スライダー４ｂの下面と面一に収容固着されている。
更に、スライダー４ｂは、相対するガイド４ａに合わせて極力幅狭く形成し、フレーム両側のテールローラの外周面に沿って移動する時、搬送用ベルト２の搬送面から立ち上がらず、ワークがスムーズに乗り移るようにする。 Like the guide 4a, the slider 4b that engages with the guide 4a is formed into a short rod shape by a synthetic resin material or a metal material, and is fitted and attached from the longitudinal end portion of the guide 4a, along the longitudinal direction of the guide. And is slidable. Note that the method of slidably mounting the slider 4b on the guide 4a is not limited to the above-described method of fitting from the end of the guide 4a, and the slider 4b is fitted from any position within the length of the guide 4a. You may comprise so that it may obtain.
The slider 4b has a workpiece support member 3 attached to one side of the upper surface, and a recess 12 cut out in the lower surface. The recess 12 is one of constituent members of the sorting guide means 5 and the origin return guide means 6. A magnet (magnetic body) 13 is housed and fixed flush with the lower surface of the slider 4b.
Further, the slider 4b is formed to be as narrow as possible in accordance with the opposing guide 4a. When the slider 4b moves along the outer peripheral surface of the tail roller on both sides of the frame, the slider 4b does not stand up from the conveying surface of the conveying belt 2 and the workpiece smoothly moves. Like that.

ワーク支持部材３は、ワークＷを載承し得る大きさのシートで、スライド手段４の一方の構成部材であるスライダー４ｂと、磁石１３が固着されている。
前記シートは、搬送用ベルト２と同様、フレーム両側のテールローラの外周面に沿って折り返す時、搬送用ベルトに追従して折り返すことができる屈曲性、可撓性を有した部材、例えば、合成樹脂製シート、布地、網地、プラスチックモジュールベルト等の一枚物、或いは前記部材からなる小片を連結して一枚物としたもの等、何れでもよい。そして、これら部材によって形成されるワーク支持部材３の平面視形状は、長方形、正方形、円形、楕円形等、何れでもよい。 The work support member 3 is a sheet having a size capable of mounting the work W, and a slider 4b, which is one constituent member of the slide means 4, and a magnet 13 are fixed thereto.
Similar to the conveyance belt 2, the sheet is a flexible or flexible member that can be folded back following the conveyance belt when folded along the outer peripheral surface of the tail roller on both sides of the frame, for example, a synthetic material. It may be a single sheet such as a resin sheet, fabric, mesh, plastic module belt, or a single piece formed by connecting small pieces made of the above members. The planar shape of the work support member 3 formed by these members may be any of a rectangle, a square, a circle, an ellipse, and the like.

前記ワーク支持部材３の一側部は、前記スライダー４ｂの上面に載置され、その上に押え材１４が載置され、止ネジ１５で固定されている。従って、仮にワーク支持部材３が損傷した場合は、止ネジ１５を緩めて押え材１４を外せばワーク支持部材３はスライダー４ｂから分離でき、新しいワーク支持部材３に交換することができる。   One side portion of the work support member 3 is placed on the upper surface of the slider 4 b, and a presser material 14 is placed thereon and fixed with a set screw 15. Therefore, if the work support member 3 is damaged, the work support member 3 can be separated from the slider 4b and replaced with a new work support member 3 by loosening the set screw 15 and removing the presser material 14.

搬送用ベルト２の外表面に前記スライド手段４で該ベルトの幅方向にスライド可能に支持されたワーク支持部材３を、搬送用ベルト２の始端側における幅方向の中央位置から終端側における幅方向複数の仕分け位置（図面では左側、中央、右側の３方向）に案内する仕分け案内手段５は、前記上トラフ１ｂの表面に、搬送用ベルトの回動方向始端側から終端側に向かって分岐配設した仕分け軌条１６と、その仕分け軌条１６の手前側に配置した仕分け切替軌条１７とで構成されている。そして、仕分け軌条１６及び仕分け切替軌条１７は、磁石を直線状に配置して形成されている。   The work supporting member 3 supported on the outer surface of the conveying belt 2 by the slide means 4 so as to be slidable in the width direction of the belt is moved from the center position in the width direction on the start end side to the end direction in the width direction on the end side. The sorting guide means 5 for guiding to a plurality of sorting positions (three directions on the left side, the center, and the right side in the drawing) is branched on the surface of the upper trough 1b from the start side toward the end side in the rotation direction of the transport belt. The sorting rail 16 is provided, and the sorting switching rail 17 is arranged on the front side of the sorting rail 16. The sorting rail 16 and the sorting switching rail 17 are formed by linearly arranging magnets.

前記仕分け軌条１６は、図２に示すようにトラフ１ｂの始端寄りの幅方向における略中央位置から終端側に向かって左側軌条１６ａ、中央軌条１６ｂ、右側軌条１６ｃの三方向に分岐配設され、その各軌条１６ａ，１６ｂ，１６ｃは磁石を直線状に並べて構成されている。図示の実施例では、左側軌条１６ａと右側軌条１６ｃは中心線に対しそれぞれ等角度の開き角で構成されている。
前記左側軌条１６ａ、中央軌条１６ｂ、右側軌条１６ｃは、前記上トラフ１ｂが磁石に対して吸着作用を生じる金属平板で構成されている場合、該上トラフ１ｂの軌条線上に開設した溝に非磁性体からなる台枠１８を嵌着固定し、その台枠１８にブロック状をしたＮ極又はＳ極の磁石１９を密着させて一直線状に並べて構成されている。尚、一直線状に並べる磁石１９相互の間隔は、磁石の吸着作用が寸断されず、搬送用ベルト２の回動により軌条に沿って案内動作が連続的に行われる間隔とする。
又、トラフ１ｂが非磁性体の平板で構成されている場合も前記台枠１８を使用することで磁石１９の配列固定を容易に行うことができる。勿論、上トラフ１ｂに直接磁石１９を並べ固定してもよい。そして、前記磁石１９の表面は上トラフ１ｂの表面と面一に仕上げられている。
前記磁石１９はブロック状に限らず、軌条の長さを有した長尺一本ものであってもよい。
そして、前記左側軌条１６ａと右側軌条１６ｃの始端側の手前位置には、左側軌条１６ａ及び右側軌条１６ｃの略延長線が交差する点を回転中心として回動する仕分け切替軌条１７が配置されている。 As shown in FIG. 2, the sorting rail 16 is branched and arranged in three directions, that is, a left rail 16a, a central rail 16b, and a right rail 16c from the approximate center position in the width direction near the start end of the trough 1b toward the end side. Each of the rails 16a, 16b, and 16c is configured by arranging magnets in a straight line. In the illustrated embodiment, the left rail 16a and the right rail 16c are each configured with an opening angle that is equiangular with respect to the center line.
The left rail 16a, the central rail 16b, and the right rail 16c are non-magnetic in the groove formed on the rail line of the upper trough 1b when the upper trough 1b is formed of a metal flat plate that generates an attracting action on the magnet. A frame 18 made of a body is fitted and fixed, and a block-shaped N pole or S pole magnet 19 is brought into close contact with the frame 18 and arranged in a straight line. The interval between the magnets 19 arranged in a straight line is an interval at which the attracting action of the magnets is not interrupted and the guiding operation is continuously performed along the rails by the rotation of the conveying belt 2.
Further, even when the trough 1b is formed of a non-magnetic flat plate, the arrangement of the magnets 19 can be easily fixed by using the frame 18. Of course, the magnets 19 may be arranged and fixed directly on the upper trough 1b. The surface of the magnet 19 is finished flush with the surface of the upper trough 1b.
The magnet 19 is not limited to a block shape, and may be a single long piece having a rail length.
A sorting switching rail 17 that rotates around a point where the substantially extended lines of the left rail 16a and the right rail 16c intersect is disposed at a position near the start end of the left rail 16a and the right rail 16c. .

前記仕分け切替軌条１７は、コンベヤの始端側において搬送用ベルト２の幅方向中央位置（原点位置）に位置するワーク支持部材３を、三方向に分岐する仕分け軌条１６（左側軌条１６ａ、中央軌条１６ｂ、右側軌条１６ｃ）の何れかに乗り移るように切り替えるもので、所定の角度範囲（中心線に対し左右等角度）内を揺動するように構成されている。
その構成は、トラフ１ｂに上記角度の揺動を可能とする平面視略扇形の窓孔２０が開口され、その窓孔２０内に仕分け切替軌条１７が、前記左側軌条１６ａと右側軌条１６ｃの略延長線が交差する交差点（Ｏ）上を回転中心として揺動可能に軸支されている。
また、仕分け切替軌条１７は、前記仕分け軌条１６と同様、非磁性体からなる帯状台枠２２に仕分け軌条１６に配列したと同じ極の磁石２３を一列に配列固定して構成されている。該磁石２３は、ブロック状、長尺一本ものの何れでもよい。 The sorting switching rail 17 is a sorting rail 16 (left rail 16a, central rail 16b) that branches the work support member 3 positioned at the center position (origin position) in the width direction of the conveying belt 2 on the start end side of the conveyor in three directions. The right rail 16c) is switched so as to be transferred to any one of the right rails 16c), and is configured to swing within a predetermined angle range (equal left and right angles with respect to the center line).
The configuration is such that a trough 1b is provided with a substantially fan-shaped window hole 20 in plan view that enables the angle to be swung, and a sorting switching rail 17 is provided in the window hole 20 for the left rail 16a and the right rail 16c. It is pivotally supported so that it can swing around the intersection (O) where the extension lines intersect.
Similarly to the sorting rail 16, the sorting switching rail 17 is configured by arranging and fixing magnets 23 having the same poles as the sorting rail 16 on a strip-like frame 22 made of a non-magnetic material in a row. The magnet 23 may be either a block shape or a long one.

そして、前記仕分け切替軌条１７を左右方向に揺動する機構は、前記トラフ１ｂに開設した窓孔２０の略真中を横切るように作動杆２１を搬送用ベルト幅方向にスライド可能に横架し、その作動杆２１と前記仕分け切替軌条１７とをピンで連結する。
それにより、作動杆２１をスライドすることにより仕分け切替軌条１７はＯ点を中心として左右方向に揺動する。左に揺動すれば、仕分け切替軌条１７は左側軌条１６ａの延長線上に並び、右側に揺動すれば仕分け切替軌条１７は右側軌条１６ｃの延長線上に並び、左右何れの方向にも揺動させず中心線上に位置させれば中央軌条１６ｂの延長線上に並ぶ。
尚、前記作動杆２１のスライドは、手動操作でもよいが、仕分け作業の効率化を図る場合は、シリンダや電磁ソレノイド、モータ等の動力手段を用い、その動力手段をワークＷ毎に設定された仕分け情報を検出する検出センサの検出信号に基づいて自動的に作動するように構成する。 The mechanism for swinging the sorting switching rail 17 in the left-right direction lays the operating rod 21 so as to be slidable in the conveying belt width direction so as to cross substantially the middle of the window hole 20 established in the trough 1b. The operating rod 21 and the sorting switching rail 17 are connected by a pin.
As a result, by sliding the operating rod 21, the sorting switching rail 17 swings in the left-right direction around the point O. If it is swung to the left, the sorting switching rail 17 is arranged on the extension line of the left side rail 16a, and if it is swung to the right side, the sorting switching rail 17 is arranged on the extension line of the right rail 16c, and is swung in either direction. If they are positioned on the center line, they are aligned on the extension line of the central rail 16b.
The slide of the operating rod 21 may be manually operated. However, in order to increase the efficiency of sorting work, power means such as a cylinder, an electromagnetic solenoid, and a motor are used, and the power means is set for each work W. It is configured to automatically operate based on a detection signal of a detection sensor for detecting sorting information.

原点復帰案内手段６は、搬送用ベルト２の回動と前記仕分け案内手段５の働きで該搬送用ベルト２の終端側における複数の仕分け位置に分岐仕分けられたワーク支持部材３を、搬送用ベルト２の始端側の原点位置（幅方向の略中央位置）に戻すもので、図４に示すように、搬送用ベルト２の復路側より上方に架設配置した下トラフ１ｂ’の裏面（搬送用ベルトの復路側と対向する面）に、前記搬送用ベルト２の回動方向終端側の中央位置を除いた左側と右側の二方向から始端側の原点位置の手前位置に向かって原点復帰軌条２４ａ，２４ｂが配設され、その原点復帰軌条２４ａ，２４ｂは磁石２６を一直線状に並べて構成されている。   The origin return guide means 6 is configured to feed the work support member 3 branched and divided into a plurality of sorting positions on the terminal end side of the conveyor belt 2 by the rotation of the conveyor belt 2 and the function of the sorting guide means 5. 2 is returned to the origin position (substantially central position in the width direction) on the start end side, and as shown in FIG. 4, the back surface (conveying belt) of the lower trough 1b 'laid and arranged above the return path side of the conveying belt 2 On the return path side), the origin return rail 24a from the two directions on the left and right sides excluding the central position on the end side in the rotational direction of the conveyor belt 2 toward the position just before the origin position on the start end side. The origin return rails 24a and 24b are configured by arranging magnets 26 in a straight line.

前記原点復帰軌条２４ａ，２４ｂを構成する磁石２６の配置は、前記仕分け軌条１６及び仕分け切替軌条１７と同様、前記トラフ１ｂ’の軌条線上に開設した溝に非磁性体からなる台枠２５を嵌着固定し、その台枠２５に、仕分け軌条１６及び仕分け切替軌条１７に固着したと同じ極の磁石２６を一直線状に並べて構成されている。   The arrangement of the magnets 26 constituting the origin return rails 24a and 24b is similar to the sorting rail 16 and the sorting switching rail 17 in that a base frame 25 made of a non-magnetic material is fitted in a groove formed on the rail line of the trough 1b '. The magnet 26 having the same polarity as that fixed to the sorting rail 16 and the sorting switching rail 17 is arranged in a straight line on the underframe 25.

又、上記原点復帰軌条２４ａ，２４ｂは、前記上トラフ１ｂに配設した仕分け軌条１６の左側軌条１６ａと右側軌条１６ｃを下トラフ１ｂ’にそのまま投影した状態で形成してもよいが、図４に示すように往路の中心線に対する左側軌条１６ａ、右側軌条１６ｃの開き角より僅か大きい開き角で配置し、始端寄りの先端部は機長方向にずらして中心線上に配置されている。
それにより、仕分け完了後のワーク支持部材３は分岐仕分けの位置に保持されたまま搬送用ベルト２の回動で復路側に折り返され、搬送用ベルト２の回動で始端側に移動される。その移動の途中にワーク支持部材３のスライダー４ｂに固着された磁石１３は、原点復帰軌条２４ａ，２４ｂと交差する。交差後は、スライダー４ｂの磁石１３と、原点復帰軌条２４ａ，２４ｂの磁石２６が吸着しあい、搬送用ベルト２の回動により始端側に一緒に搬送されながら該搬送用ベルト２上を幅方向に移動し、搬送用ベルト２の幅方向所定位置に設定された原点位置に移動復帰される。そして、原点復帰軌条２４ａ，２４ｂの開き角が仕分け軌条の開き角より大きくしてあることで、ワーク支持部材３のスライダー４ｂに固着した磁石１３が確実に原点復帰軌条２４ａ，２４ｂと交差し、磁石の吸着作用による案内動作が確実に行われる。 The origin return rails 24a and 24b may be formed in a state in which the left rail 16a and the right rail 16c of the sorting rail 16 disposed on the upper trough 1b are projected as they are onto the lower trough 1b ′. As shown in FIG. 2, the left rail 16a and the right rail 16c are arranged at an opening angle slightly larger than the opening angle of the right rail 16c with respect to the center line of the forward path, and the tip end closer to the start end is shifted on the center line and arranged on the center line.
Thereby, the work support member 3 after completion of sorting is folded back to the return path side by the rotation of the transport belt 2 while being held at the branch sorting position, and moved to the start end side by the rotation of the transport belt 2. The magnet 13 fixed to the slider 4b of the workpiece support member 3 during the movement intersects the origin return rails 24a and 24b. After the crossing, the magnet 13 of the slider 4b and the magnets 26 of the origin return rails 24a and 24b are attracted to each other, and are transported together to the start end side by the rotation of the transport belt 2 while moving on the transport belt 2 in the width direction. It moves and returns to the origin position set at a predetermined position in the width direction of the conveyor belt 2. And since the opening angle of the origin return rails 24a and 24b is larger than the opening angle of the sorting rail, the magnet 13 fixed to the slider 4b of the workpiece support member 3 surely intersects the origin return rails 24a and 24b, Guide operation by the magnet's attracting action is reliably performed.

搬送用ベルト２を駆動回動する駆動手段７は、搬送用ベルト２の外表面に配設したガイド手段４のガイドの幅方向端部より幅方向外方に延びる該ベルトの側部を上下より挟持する上下一対の駆動回転帯２７,２７’で構成され、その上下一対の駆動回転帯２７，２７’は、搬送用ベルト２の復路側の中程位置に位置させて該ベルトの幅方向両側に配置されている。   The driving means 7 for driving and rotating the conveying belt 2 has a side portion of the belt extending outward in the width direction from the width direction end of the guide of the guide means 4 disposed on the outer surface of the conveying belt 2 from above and below. The pair of upper and lower drive rotation bands 27 and 27 ′ is sandwiched between the upper and lower drive rotation bands 27 and 27 ′. Is arranged.

上下一対の駆動回転帯２７，２７’は図３（ｂ）に示すように、機長方向に所定の間隔をおいて回転可能に軸支した歯付きプーリ２７ａとプーリ２７ａ’、プーリ２７ａ’とプーリ２７ａ’に亘って歯付きベルト２７ｂが巻回され、その歯付きベルト２７ｂの平滑な外周面に磁石２７ｃが該ベルトの周方向に一定ピッチで取り付けられている。
歯付きベルト２７ｂに対する磁石２７ｃの取付は、矩形平板状の磁石２７ｃを樹脂製の磁石ホルダ２７ｄに内蔵し、その磁石ホルダ２７ｄは固定ブラケットを用いて歯付きベルト２７ｂに定着固定する。
又、上下の駆動回転帯２７，２７’に装備する磁石２７ｃは、搬送用ベルト２を挟んで対向した時、両方の磁石２７ｃが吸着し合うように、Ｎ極とＳ極が対応するように配置されている。その配置は、例えば、上側の駆動回転帯２７の磁石２７ｃの磁極をＳ極とした場合、下側の駆動回転帯２７’の磁石２７ｃの磁極はＮ極とする。又、上下の駆動回転帯２７，２７’の磁石２７ｃを、Ｓ極とＮ極が交互となるように配列するなど、何れでもよい。 As shown in FIG. 3 (b), the pair of upper and lower drive rotation bands 27 and 27 'are toothed pulley 27a and pulley 27a' rotatably supported at a predetermined interval in the machine length direction, and pulley 27a 'and pulley A toothed belt 27b is wound around 27a ', and magnets 27c are attached to the smooth outer peripheral surface of the toothed belt 27b at a constant pitch in the circumferential direction of the belt.
To attach the magnet 27c to the toothed belt 27b, a rectangular flat magnet 27c is built in a resin magnet holder 27d, and the magnet holder 27d is fixedly fixed to the toothed belt 27b using a fixing bracket.
Further, the magnets 27c provided in the upper and lower drive rotation bands 27 and 27 'are arranged so that the N pole and the S pole correspond so that both the magnets 27c are attracted to each other when opposed to each other with the conveying belt 2 interposed therebetween. Is arranged. For example, when the magnetic pole of the magnet 27c of the upper drive rotation band 27 is an S pole, the magnetic pole of the magnet 27c of the lower drive rotation band 27 ′ is an N pole. Further, the magnets 27c of the upper and lower drive rotation bands 27 and 27 ′ may be arranged so that the S poles and the N poles are alternately arranged.

そして、上記した上下一対の駆動回転帯２７，２７’は、搬送用ベルト２の復路側の上側に配置した駆動回転帯２７をモータ２８で駆動回転し、搬送用ベルト２の復路側の下側に配置した駆動回転帯２７’は前記上側の駆動回転帯２７との吸着により従動回転するように構成されている。又、モータ２８の回転力は、搬送用ベルト２の幅方向両側に配置した駆動手段７の何れか一方（図面では搬送用ベルトの左側）に伝達し、両駆動手段７の歯付きプーリ２７ａを軸３２で連結し、両方の駆動手段の歯付きプーリ２７ａが駆動回転するように構成されている。
尚、駆動手段７を構成する上下一対の駆動回転帯２７，２７’のうち、搬送用ベルト２の下側に配置する駆動回転帯２７’は、搬送用ベルトに対して接離切替可能に構成することで、該搬送用ベルト２の交換を容易に行うことが可能となる。 The above-described pair of upper and lower drive rotation bands 27 and 27 ′ are driven and rotated by the motor 28 with respect to the drive rotation band 27 disposed on the upper side of the return path side of the transport belt 2, and the lower side of the return path side of the transport belt 2. The drive rotation band 27 ′ arranged in the above is configured to be driven and rotated by suction with the upper drive rotation band 27. Further, the rotational force of the motor 28 is transmitted to one of the drive means 7 disposed on both sides in the width direction of the transport belt 2 (on the left side of the transport belt in the drawing), and the toothed pulley 27a of both drive means 7 is transmitted. The shafts 32 are connected so that the toothed pulleys 27a of both driving means are driven to rotate.
Of the pair of upper and lower drive rotation bands 27 and 27 ′ constituting the drive means 7, the drive rotation band 27 ′ disposed on the lower side of the conveyance belt 2 is configured to be able to be switched to and away from the conveyance belt. As a result, the transfer belt 2 can be easily replaced.

また、搬送用ベルト２の復路側の下方には、該搬送用ベルト２の外表面にスライド手段４を介して取り付けたワーク支持部材３が、復路側を移動するとき垂直下方に垂れ下がるのを防止する垂れ防止部材２９が搬送用ベルト２の復路側と僅少間隔をおいて略平行に架設されている。
その垂れ防止部材２９は図５に示すように、分岐仕分けタイプの場合、復路側の始端部においてベルト幅の略全域を通過移動するワーク支持部材３を支え、復路側の終端部（原点位置）に向かってベルト幅方向の略中央位置に移動するワーク支持部材を支えるよう、パイプ材（図面では角パイ）２９ａを組んで構成されている。尚、垂れ防止部材２９の枠組みの形態は、図示の形態に限定されず、要はワーク支持部材３が復路側を移動する時、シート部分が下方に垂れ下がるのを防止できればよく、従って、平板を水平に架設してもよいものである。 In addition, the work support member 3 attached to the outer surface of the conveyor belt 2 via the slide means 4 is prevented from drooping vertically downward when moving on the return path side. A drooping prevention member 29 is installed substantially parallel to the return path side of the conveying belt 2 with a slight gap.
As shown in FIG. 5, in the case of the branch sorting type, the sagging prevention member 29 supports the work supporting member 3 that moves and moves through substantially the entire belt width at the start end on the return path side, and ends on the return path side (origin position). A pipe material (square pie in the drawing) 29a is assembled so as to support the work supporting member that moves to the substantially central position in the belt width direction. The form of the frame of the sag prevention member 29 is not limited to the form shown in the figure. In short, it is only necessary to prevent the sheet portion from hanging down when the work support member 3 moves on the return path side. It can be installed horizontally.

次に、上記磁石の吸着作用を利用した分岐仕分けタイプの仕分けコンベヤの仕分け動作を図８〜図１０に基づいて説明する。
仕分けコンベヤの始端側に配置した搬入コンベヤ３０から該仕分けコンベヤへのワークＷの乗り移りは図８（ａ）〜図８（ｄ）に示すように、搬送用ベルト２の外表面にスライド手段４を介して取り付けられたワーク支持部材３が、搬送用ベルト２の回動によって復路側から往路側に戻り、ワーク支持部材３が始端部の原点位置に現れたときに搬入コンベヤ３０からワークＷが該ワーク支持部材３に乗り移り、仕分けコンベヤの終端方向に向けて搬送される。 Next, the sorting operation of the branch sorting type sorting conveyor using the magnet attracting action will be described with reference to FIGS.
As shown in FIGS. 8 (a) to 8 (d), the transfer of the work W from the carry-in conveyor 30 arranged on the start end side of the sorting conveyor to the sorting conveyor is performed by placing the sliding means 4 on the outer surface of the conveying belt 2. The workpiece support member 3 attached via the conveyor belt 2 returns from the return path side to the forward path side by the rotation of the conveying belt 2, and when the workpiece support member 3 appears at the origin position of the start end, the workpiece W is transferred from the carry-in conveyor 30. It transfers to the workpiece support member 3 and is conveyed toward the end direction of the sorting conveyor.

そして、ワークＷを載せたワーク支持部材３は図９（ａ）に示すようにスライド手段４でベルト幅方向の略中央位置に保持されたまま該搬送用ベルト２の回動と一緒に移動し、ワーク支持部材３を連結するスライダー４ｂが仕分け案内手段５の仕分け切替軌条１７の直上に位置する。それにより、該スライダー４ｂに固着した磁石１３と、前記仕分け切替軌条１７の磁石２３が吸着し合い、ワーク支持部材３は仕分け切替軌条１７の方向に案内される。この時、仕分け切替軌条１７は、搬入コンベヤの終端近傍に配置した検出センサ４４（図１参照）で、ワークＷ毎に設定された仕分け情報（例えば、色彩）を検知し、その検出した情報に基づいて前記仕分け切替軌条１７が揺動切り替えられる。図示は、三方向に分岐仕分ける場合、右側に仕分けるワークを示す。   Then, the work supporting member 3 on which the work W is placed is moved together with the rotation of the conveying belt 2 while being held at a substantially central position in the belt width direction by the sliding means 4 as shown in FIG. 9A. The slider 4b for connecting the workpiece support member 3 is located immediately above the sorting switching rail 17 of the sorting guide means 5. As a result, the magnet 13 fixed to the slider 4 b and the magnet 23 of the sorting switching rail 17 are attracted to each other, and the workpiece support member 3 is guided in the direction of the sorting switching rail 17. At this time, the sorting switching rail 17 detects sorting information (for example, color) set for each workpiece W by the detection sensor 44 (see FIG. 1) arranged near the end of the carry-in conveyor, and uses the detected information. Based on this, the sorting switching rail 17 is switched over. The figure shows a work to be sorted on the right side when branching in three directions.

ワーク支持部材３に載ったワークＷが右側に仕分けるワークである場合、図９（ｂ）に示すように前記仕分け切替軌条１７は中立の位置から右側に揺動される。この仕分け切替軌条１７の揺動によりワーク支持部材３は、スライド手段４によって搬送用ベルト２の幅方向右側に移動する。前記仕分け切替軌条１７は右側軌条１６ｃの略延長線上に並び、図９（ｃ）及び図１０（ａ）に示すようにワーク支持部材３は搬送用ベルト２の回動により仕分け軌条１６の右側軌条１６ｃに沿って案内され、ワークＷは所定の仕分け位置（右側）に仕分けられる。
即ち、搬送用ベルト２にスライド手段４で幅方向に移動可能に支持されたワーク支持部材３は、該搬送用ベルト２の回動によって一緒に終端側に移動するが、ワーク支持部材３を固着したスライダー４ｂの磁石１３は搬送用ベルト２の往路側の下に位置する上トラフ１ｂに配設した仕分け軌条１６に沿って固着した磁石１９と対応吸着する。それにより、搬送用ベルト２の回動によりワーク支持部材３は終端側に向けて移動しながら、仕分け軌条１６の磁石１９に沿ってベルトの幅方向に移動され、所定の仕分け位置に仕分けられ、仕分けコンベヤの終端側に連設配置した搬出コンベヤ３１に搬出される。
尚、図１において、ワークＷ（丸）は右側、ワークＷ（四角）は左側、ワークＷ（三角）は中央の仕分けを示す。 When the workpiece W placed on the workpiece support member 3 is a workpiece sorted to the right side, as shown in FIG. 9B, the sorting switching rail 17 is swung to the right from the neutral position. The workpiece support member 3 is moved to the right in the width direction of the conveying belt 2 by the slide means 4 by the swing of the sorting switching rail 17. The sorting switching rails 17 are arranged on a substantially extended line of the right rail 16c, and the work support member 3 is rotated by the conveyor belt 2 as shown in FIGS. 9 (c) and 10 (a). Guided along 16c, the workpiece W is sorted into a predetermined sorting position (right side).
That is, the work support member 3 supported by the transfer belt 2 so as to be movable in the width direction by the slide means 4 moves together with the rotation of the transfer belt 2, but the work support member 3 is fixed. The magnet 13 of the slider 4b adsorbed correspondingly to the magnet 19 fixed along the sorting rail 16 disposed on the upper trough 1b located below the forward path side of the conveying belt 2. Thereby, the workpiece support member 3 is moved in the belt width direction along the magnet 19 of the sorting rail 16 while moving toward the end side by the rotation of the conveying belt 2, and is sorted into a predetermined sorting position. It is carried out to the carry-out conveyor 31 arranged continuously at the terminal end side of the sorting conveyor.
In FIG. 1, the workpiece W (circle) indicates the right side, the workpiece W (square) indicates the left side, and the workpiece W (triangle) indicates the center sorting.

ワークＷを仕分け搬出したワーク支持部材３は、図１０（ｂ）に示すように仕分け終了時の位置に保持されたまま搬送用ベルト２の回動によって復路側に移動する。そして、搬送用ベルト２の回動により始端側に向かって移動するが、その移動途中に搬送用ベルト２の復路側の内側（上方）に位置する下トラフ１ｂ’に配設した原点復帰案内手段６の原点復帰軌条２４ｂとワーク支持部材３を固着したスライダー４ｂとが交差し、該スライダー４ｂに固着した磁石１３が前記原点復帰軌条２４ｂに固着した磁石２６と吸着し合う。それにより、ワーク支持部材３のスライダー４ｂは、原点復帰軌条２４ｂと吸着状態を維持するよう該軌条に沿って案内される。その結果、ワーク支持部材３は搬送用ベルト２の復路側の終端部では該ベルトの幅方向略中央位置に移動し、原点位置に復帰し、次のワークを載承する体制が整う。   As shown in FIG. 10B, the work support member 3 that has sorted and unloaded the work W moves to the return path side by the rotation of the conveying belt 2 while being held at the position at the end of sorting. Then, the carrier belt 2 moves toward the starting end side by the rotation of the conveyor belt 2, and the origin return guide means disposed on the lower trough 1b 'located on the inner side (upper side) of the conveyor belt 2 on the return path side during the movement. 6 and the slider 4b to which the workpiece support member 3 is fixed cross each other, and the magnet 13 fixed to the slider 4b is attracted to the magnet 26 fixed to the origin return rail 24b. Thereby, the slider 4b of the workpiece support member 3 is guided along the rail so as to maintain the attracting state with the origin return rail 24b. As a result, the workpiece support member 3 moves to the substantially central position in the width direction of the belt at the return path end of the conveying belt 2, returns to the origin position, and a system for mounting the next workpiece is prepared.

図１１は分岐仕分けの変形例を示し、仕分けコンベヤの始端側に縦一列で供給されたワークを、コンベヤの終端側で幅方向５箇所に分岐仕分けする例である。コンベヤの終端側で幅方向５箇所に分岐仕分ける場合、前示実施例のように始端側中央位置から終端側５箇所に向けて５本の軌条を配設してもよいが、その場合、始端側の各軌条相互は接近し、確実に分岐仕分けることが困難となる。そこで、図１１に示すように二段階に分けて分岐仕分けることで、軌条相互を吸着作用が安定して行われるだけの間隔をあけて配置することができる。即ち、一段目で前示実施例で示した三方向（左側、中央、右側）の分岐を行い、二段目で左側と右側を更に二つに分岐させることで、五方向に分岐することができる。尚、図示例は五方向の分岐仕分けであるが、前示実施例の仕分け案内手段を複数組み合わせることで並列多方向の分岐仕分けが可能となる。   FIG. 11 shows a modified example of branch sorting, in which workpieces supplied in a vertical line to the starting end side of the sorting conveyor are branched and sorted into five places in the width direction on the terminal end side of the conveyor. In the case of branching and sorting at five locations in the width direction on the end side of the conveyor, five rails may be arranged from the center position on the start end side toward the five locations on the end side as in the previous embodiment. The rails on the side approach each other and it is difficult to reliably branch and sort them. Therefore, as shown in FIG. 11, by dividing the branch into two stages, it is possible to arrange the rails with an interval enough to stably perform the adsorption action. That is, branching in three directions (left side, center, right side) shown in the previous embodiment is performed in the first stage, and branching in five directions is performed by further branching the left side and right side into two in the second stage. it can. Although the illustrated example shows five-way branch sorting, parallel multi-way branch sorting is possible by combining a plurality of sorting guide means of the previous embodiment.

図１２乃至図１６は、ワーク支持部材を、搬送用ベルトの幅方向（搬送用ベルトの回動方向に対し直交する方向）にスライドさせ仕分ける方式を、ピン案内方式とした実施例で、且つ分岐仕分けタイプの仕分けコンベヤである。尚、本実施例において、搬送用ベルト２の駆動機構及び該搬送用ベルト２に対するワーク支持部材３の取付構造（スライド手段４）は前示実施例１と同じである為、同じ部材は同一符号を付し説明を省略する。
以下、ピン案内方式による仕分け案内手段及び原点復帰案内手段について説明する。
仕分け案内手段３３は、搬送用ベルト２にスライド可能に支持されるワーク支持部材３のスライダー４ｂの長手方向の両端部上面に起立固定した案内ピン３４，３４’と、前記搬送用ベルト２の往路側上方に平面視略ハ字型に配設した仕分け用案内桟３５，３５’と、該仕分け用案内桟３５の手前側に配置した仕分け切替手段３６とで構成されている。 FIGS. 12 to 16 show an embodiment in which the work supporting member is slid in the width direction of the conveying belt (direction perpendicular to the rotation direction of the conveying belt) and the sorting method is a pin guide method and is branched. This is a sorting type sorting conveyor. In the present embodiment, the driving mechanism of the conveying belt 2 and the structure for mounting the work support member 3 to the conveying belt 2 (sliding means 4) are the same as those in the first embodiment. The description is omitted.
Hereinafter, the sorting guidance means and the origin return guidance means by the pin guidance method will be described.
The sorting guide means 33 includes guide pins 34 and 34 ′ that are erected and fixed to the upper surfaces of both longitudinal ends of the slider 4 b of the work support member 3 slidably supported by the transport belt 2, and the forward path of the transport belt 2. A sorting guide bar 35, 35 ′ arranged in a substantially C shape in plan view on the upper side, and a sorting switching means 36 arranged on the front side of the sorting guide bar 35.

前記案内ピン３４，３４’は、ワーク支持部材３の搬送方向前側に固着したスライダー４ｂに支軸３４ａを起立固着し、その支軸３４ａにローラ３４ｂを回転可能に嵌着して構成されている。このローラ３４ｂを取り付けることで案内桟との接触時に該ローラ３４ｂが回転し、摩擦抵抗が少なくスムーズに案内される。   The guide pins 34 and 34 'are configured such that a support shaft 34a is erected and fixed to a slider 4b fixed to the front side of the work supporting member 3 in the conveying direction, and a roller 34b is rotatably fitted to the support shaft 34a. . By attaching the roller 34b, the roller 34b rotates at the time of contact with the guide bar, and is smoothly guided with less frictional resistance.

前記案内ピン３４,３４’を案内する仕分け用案内桟３５，３５’は、直線状の金属製棒材或いは金属製帯板等を、搬送用ベルト２の往路側上方に、始端側が狭く終端側が拡開する平面視略ハ字型に配置して構成され、その仕分け用案内桟３５，３５’はコンベヤフレーム１に支柱やブラケット等４０を介して搬送用ベルト２上空に宙吊りされている。尚、図示の三方向に分岐仕分ける場合、案内桟３５と案内桟３５’の始端側の間隔はワーク支持部材３のスライダー４ｂの長手方向幅より僅か広い間隔とし、原点位置から中央仕分け位置にそのまま直進する場合、スライダー４ｂが案内桟３５，３５’に接触することなく通過し得るように構成されている。   The sorting guide bars 35, 35 ′ for guiding the guide pins 34, 34 ′ include a straight metal bar or a metal strip, etc., on the forward side of the transport belt 2, the start side is narrow and the end side is The guide rails 35 and 35 ′ for sorting are suspended in the air over the conveyor belt 2 via support columns, brackets 40, and the like. In the case of branching and sorting in the three directions shown in the figure, the gap between the guide bar 35 and the guide bar 35 'on the start end side is slightly wider than the longitudinal width of the slider 4b of the work support member 3, and is directly from the origin position to the center sorting position. When going straight, the slider 4b can pass without contacting the guide bars 35 and 35 '.

そして、原点位置に位置するワーク支持部材３を終端側の３箇所の仕分け位置に仕分ける場合、中央仕分け位置は上記したように仕分け用案内桟３５，３５’にワーク支持部材３の案内ピン３４，３４’が当接することなく通過することで仕分けられるが、左側への仕分けは案内ピン３４を仕分け用案内桟３５の外側に、右側への仕分けは反対側の案内ピン３４’を仕分け用案内桟３５’の外側に当接させる必要がある。
従って、ワークＷ毎に設定された仕分け情報に基づいてワークＷを載せたワーク支持部材３を仕分け用案内桟３５の手前位置で仕分ける。それを行うのが仕分け切替手段３６である。 When the work support member 3 located at the origin position is sorted into the three sorting positions on the end side, the center sorting position is arranged on the sorting guide bars 35, 35 ′ as described above, the guide pins 34 of the work support member 3, 34 'can be sorted by passing without contact, but sorting on the left side guide pins 34 on the outside of the sorting guide bar 35, and sorting on the right side on the opposite guide pin 34' for sorting on the right side. It is necessary to contact the outside of 35 '.
Therefore, based on the sorting information set for each workpiece W, the workpiece support member 3 on which the workpiece W is placed is sorted at a position before the sorting guide bar 35. The sorting switching means 36 performs this.

前記仕分け切替手段３６は、図１３（ａ），（ｂ）に示すようにワーク支持部材３のスライダー４ｂに起立固着された案内ピン３４が嵌入するだけの幅を有した断面略コ字型の案内枠３６ａと、その案内枠３６ａの長手方向の一方端（図面では右側）を回転可能に支持するブラケット３６ｂと、該ブラケット３６ｂに取り付けたステッピングモータ３６ｃと、そのモータ３６ｃの回転で前記案内枠３６ａを左右方向に水平揺動するカム３６ｄとで構成されている。
そして、前記案内枠３６ａの回転中心側は末広がり状に拡開させて、案内ピン３４が案内枠３６ａにスムーズに嵌入するように構成されている。
更に、前記仕分け切替手段３６の作動は、ワーク支持部材３の案内ピン３４が案内枠３６ａに嵌入した後に作動するが、その作動タイミングは仕分け切替手段３６より上流側に配置した位置検出センサ４５がワーク支持部材３の通過（実施例は案内ピンの通過）を検出した検出信号を受けて作動するように構成されている。 As shown in FIGS. 13 (a) and 13 (b), the sorting switching means 36 has a substantially U-shaped cross section having a width sufficient to fit the guide pin 34 that is erected and fixed to the slider 4b of the work supporting member 3. A guide frame 36a, a bracket 36b that rotatably supports one end of the guide frame 36a in the longitudinal direction (right side in the drawing), a stepping motor 36c attached to the bracket 36b, and rotation of the motor 36c results in the guide frame 36b. The cam 36d horizontally swings in the left-right direction.
The rotation center side of the guide frame 36a is widened so that the guide pin 34 fits smoothly into the guide frame 36a.
Further, the sort switching means 36 is actuated after the guide pins 34 of the work support member 3 are fitted into the guide frame 36a, but the timing of the action is determined by the position detection sensor 45 arranged upstream of the sort switching means 36. It is configured to operate in response to a detection signal that detects the passage of the work support member 3 (the passage of the guide pin in the embodiment).

図１４は前記仕分け切替手段３６における案内枠３６ａを水平揺動させる動力源にエアーシリンダ３７を用いた構成を示し、該エアーシリンダ３７の伸縮動作で案内枠３６ａを水平揺動し、案内ピン３４を介してワーク支持部材３をガイド４ａに沿って搬送用ベルトの幅方向に横移動させる。
尚、案内枠３６ａを水平揺動させる振れ幅は、左側の案内ピン３４が仕分け用案内桟３５の外側に当接する位置から右側の案内ピン３４’が仕分け用案内桟３５’の外側に当接する位置までの移動量である。 FIG. 14 shows a configuration in which an air cylinder 37 is used as a power source for horizontally swinging the guide frame 36a in the sorting switching means 36. The guide frame 36a is horizontally swung by the expansion and contraction of the air cylinder 37, and the guide pin 34 is moved. The workpiece support member 3 is moved laterally in the width direction of the conveying belt along the guide 4a.
The swing width for horizontally swinging the guide frame 36a is such that the right guide pin 34 'contacts the outside of the sorting guide bar 35' from the position where the left guide pin 34 contacts the outside of the sorting guide bar 35 '. The amount of movement to the position.

又、分岐仕分けタイプの原点復帰案内手段３８は、搬送用ベルト２の終端側で該ベルトの幅方向複数個所（３箇所）に仕分けたワーク支持部材３を始端側の原点位置（ベルト幅方向の略中央位置）に戻すもので、中央仕分けのものはそのまま変化させずに戻すことで原点位置に戻る為、左側と右側に仕分けられたワーク支持部材を原点位置に案内するように構成されている。
その構成は、搬送用ベルト２の復路側の下方位置に、仕分け用案内桟の構成部材と同様の部材からなる原点復帰用案内桟３９，３９’を、前記仕分け案内手段３３の仕分け用案内桟３５，３５’を投影した位置より僅か外側に移動させて配置する。
何故ならば、搬送用ベルト２の幅方向外側に位置するワーク支持部材３を幅方向略中央の原点位置に移動させる場合、スライダー４ｂに固着した案内ピン３４，３４’は仕分け時とは逆に、搬送用ベルト２の回動方向に向かって幅狭くなるように配置した原点復帰用案内桟３９,３９’の内側に当接させて案内しなければならない。そして、原点復帰用案内桟３９，３９’を仕分け用案内桟３５，３５’より外側に位置させることで、多少のずれが生じても案内ピン３４，３４’は間違いなく原点復帰用案内桟３９，３９’の内側に当接させることができる。そして、上記原点復帰用案内桟３９，３９’は仕分け用案内桟３５，３５’の取り付けと同様、コンベヤフレーム１に支柱やブラケット等を介して支持されている。 Further, the branch sorting type origin return guide means 38 has the work support members 3 sorted at a plurality of locations (three locations) in the width direction of the belt 2 on the end side of the conveying belt 2 and the origin position (in the belt width direction) of the start end side. It is configured to guide the workpiece support members sorted on the left side and the right side to the origin position because the center sorting type returns to the origin position by returning without change. .
The configuration is such that origin return guide bars 39, 39 ′ made of the same members as the constituent members of the sorting guide bars are arranged at the lower position on the return path side of the conveying belt 2 and the sorting guide bars of the sorting guide means 33. 35 and 35 'are moved slightly outside the projected position.
This is because when the work supporting member 3 positioned outside the conveying belt 2 in the width direction is moved to the origin position at the substantially center in the width direction, the guide pins 34 and 34 'fixed to the slider 4b are opposite to the sorting. The guide belt 39 must be brought into contact with the inner sides of the origin return guide bars 39, 39 ′ arranged so as to become narrower in the rotation direction of the conveying belt 2. The origin return guide bars 39, 39 ′ are positioned outside the sorting guide bars 35, 35 ′, so that the guide pins 34, 34 ′ are definitely positioned at the origin return guide bars 39 even if a slight deviation occurs. , 39 '. The origin return guide bars 39, 39 ′ are supported on the conveyor frame 1 via columns, brackets, and the like, as with the attachment of the sorting guide bars 35, 35 ′.

又、図１２に示すように、搬送用ベルト２の折り返し部に、該ベルトの外表面に取り付けられたワーク支持部材３が往路側から復路側に、復路側から往路側に折り返す時、ワーク支持部材が跳ね返るのを防止する跳ね返り防止手段Ｘが配置されている。以下、その具体的な構成を図面に基づいて説明する。
搬送用ベルト２の回動方向始端側と終端側の外側には、該ベルト２の外表面に取り付けられるワーク支持部材３が往路側から復路側に、復路側から往路側にそれぞれ折り返す時、ワーク支持部材３が跳ね返るのを防止する跳ね返り防止杆４１が取り付けられている。
前記跳ね返り防止杆４１は、図１６に示すようにパイプ又は棒杆を略Ｌ字型に屈曲し、これを始端側と終端側のワーク支持部材３が通過する位置に、ワーク支持部材３の横幅より僅か幅狭い間隔をおき、且つ搬送用ベルト２の外表面と所定の間隔（ワーク支持部材が通過し得る間隔）をおいて平行に配置されている。
この跳ね返り防止杆４１の存在により、搬送用ベルト２の回動と共にワーク支持部材３が往路側から復路側へ、又復路側から往路側に折り返す時、搬送用ベルト２の外表面に重なった状態で移動される。それにより、終端側においては仕分けコンベヤから搬出コンベヤに搬出したワークＷがワーク支持部材の跳ね返りで姿勢（方向）を変え、始端側においては搬入コンベヤからワーク支持部材に乗り移る動作に支障をきたすといった問題を解消できる。 Further, as shown in FIG. 12, when the work support member 3 attached to the outer surface of the conveyor belt 2 is folded back from the forward path side to the return path side and from the return path side to the forward path side, A rebound preventing means X for preventing the member from rebounding is disposed. Hereinafter, the specific structure is demonstrated based on drawing.
When the work supporting member 3 attached to the outer surface of the belt 2 is turned from the forward path side to the return path side and from the return path side to the forward path side, the A rebound prevention bar 41 for preventing the support member 3 from rebounding is attached.
As shown in FIG. 16, the bounce prevention rod 41 is formed by bending a pipe or a rod rod into a substantially L shape, and at the position where the work support member 3 on the start side and the end side passes through this, The gap is slightly narrower and is arranged in parallel with the outer surface of the conveying belt 2 with a predetermined gap (interval through which the work support member can pass).
Due to the presence of the bounce prevention rod 41, the work support member 3 is overlapped with the outer surface of the conveyor belt 2 when the workpiece support member 3 is turned from the forward path side to the return path side and from the return path side to the forward path side as the transport belt 2 rotates. It is moved with. As a result, the work W carried out from the sorting conveyor to the carry-out conveyor changes its posture (direction) due to the rebound of the work support member at the end side, and the operation of transferring from the carry-in conveyor to the work support member is hindered at the start end side. Can be eliminated.

前記跳ね返り防止杆４１は、ブラケット８の起伏動に対応できるよう上下方向に移動調節可能に支持されている。
尚、この跳ね返り防止杆４１は、前示実施例１において図示を省略したが、実施例１においても有効に作用するものである。又、前示実施例１に示した復路側の垂れ防止部材は本実施例２において図示を省略したが、実施例１と同様に設置して同様の効果を期待することができる。 The rebound preventing rod 41 is supported so as to be movable in the vertical direction so that it can cope with the up-and-down movement of the bracket 8.
The bounce prevention rod 41 is not shown in the first embodiment, but also works effectively in the first embodiment. Further, although the illustration of the anti-sagging member on the return path shown in the first embodiment is omitted in the second embodiment, the same effect can be expected by installing the same as in the first embodiment.

図１７乃至図２０は、前記跳ね返り防止手段Ｘを、磁石の吸着作用を利用して構成した形態を示す。
その構成は図１２に示したと同様、コンベヤの始端側及び終端側におけるワーク支持部材３が通過する位置、即ち、図示の分岐仕分けタイプの場合、始端側は搬送用ベルトの幅方向略中央位置に、終端側は分岐仕分けされる各仕分け路の幅方向略中央位置に、磁石を配置し、他方、ワーク支持部材３の搬送方向に沿った後半部の幅方向略中央線上に前記磁石と吸着作用を生じる磁性体（例えば、鉄板）が直線状に取り付けられて構成されている。 FIGS. 17 to 20 show a configuration in which the rebound preventing means X is configured using a magnet attracting action.
The configuration is the same as shown in FIG. 12, the position where the workpiece support member 3 passes on the start end side and the end end side of the conveyor, that is, in the case of the illustrated branch sorting type, the start end side is at a substantially central position in the width direction of the conveyor belt. On the other hand, a magnet is arranged at a substantially central position in the width direction of each sorting path to be branched and sorted, and on the other hand, the magnet and the attracting action on the substantially center line in the width direction of the second half along the conveying direction of the work support member 3 The magnetic body (for example, iron plate) which produces is linearly attached and comprised.

折り返し部材を構成する上側のテールローラ９は、短尺のローラを搬送用ベルトの幅方向に所定間隔をおいて並列配置して構成し、その短尺の各テールローラはそれぞれホルダに軸受を介して回転可能に支持し、テールローラ間には、前記テールローラの外径と略同径で、外周にマグネットリング４４がブラケット４５を介して回転可能に取り付けられている。そして、前記マグネットリング４４はテールローラ９と略同芯上に配置されている。   The upper tail roller 9 constituting the folding member is configured by arranging short rollers in parallel at a predetermined interval in the width direction of the conveying belt, and each of the short tail rollers is rotated by a holder via a bearing. Between the tail rollers, a magnet ring 44 is rotatably attached via a bracket 45 between the tail rollers so as to have substantially the same diameter as the outer diameter of the tail rollers. The magnet ring 44 is disposed substantially concentrically with the tail roller 9.

そして、始端側には前記マグネットリング４４の手前側位置、即ち、マグネットリング４４と下側のテールローラ９’との間に磁石を内蔵したマグネットプレート４６が配置され、終端側にはマグネットリング４４の手前側に位置する上トラフ１ｂ上に磁石を内蔵したマグネットプレート４７及びマグネットリング４４と下側のテールローラ９’との間には磁石を内蔵したマグネットプレート４６’が配置されている。   A magnet plate 46 containing a magnet is disposed on the front end side, that is, on the front side of the magnet ring 44, that is, between the magnet ring 44 and the lower tail roller 9 ', and on the end side, the magnet ring 44 is disposed. On the upper trough 1b located on the near side, a magnet plate 47 containing magnets and a magnet plate 46 'containing magnets are arranged between the magnet ring 44 and the lower tail roller 9'.

前記マグネットプレート４６，４６’は、矩形平板状の磁石４６ｂを適宜数、搬送方向に並べて構成されている。そして、マグネットプレート４６，４６’は、その外表面（搬送用ベルトの内表面と対向する面）が前記マグネットリング４４と下側のテールローラ９’の共通の接線と略面一となるように傾斜させて配置されている。   The magnet plates 46 and 46 'are configured by arranging an appropriate number of rectangular flat magnets 46b in the transport direction. The outer surfaces of the magnet plates 46 and 46 '(the surface facing the inner surface of the conveyor belt) are substantially flush with the common tangent line between the magnet ring 44 and the lower tail roller 9'. It is inclined and arranged.

前記マグネットプレート４７は、前記マグネットプレート４６，４６’と同様、矩形平板状の磁石４７ｂを適宜数、搬送方向に並べて構成されている。そして、そのマグネットプレート４７の長さ（ワーク支持部材の移動方向に沿った長さ）は、ワーク支持部材３を吸着保持する距離に応じて決定され、その長さに応じて内蔵する磁石の個数も決定される。   Similar to the magnet plates 46 and 46 ′, the magnet plate 47 is configured by arranging an appropriate number of rectangular flat-plate magnets 47 b in the transport direction. The length of the magnet plate 47 (the length along the moving direction of the work support member) is determined according to the distance at which the work support member 3 is attracted and held, and the number of built-in magnets according to the length. Is also determined.

他方、ワーク支持部材３における幅方向の略中央線上には、前記マグネットリング４４、マグネットプレート４６，４６’、マグネットプレート４７の各磁石と吸着作用を生じる磁性体（例えば、鉄板）４８が、該ワーク支持部材３の後端側（搬送用ベルトに係着された側と反対側）から前端側に向かって所定範囲（少なくとも、ワーク支持部材の全長の略１／３〜１／２）に取り付けられている。
又、ワーク支持部材３に取り付ける磁性体４８の形態は、該ワーク支持部材３がプラスチックモジュールベルトである場合、その構成部材（モジュール）を連結する樹脂製軸４９に嵌着し得る金属製短尺パイプで構成する。尚、ワーク支持部材３が一枚もののシートである場合、磁性体４８は矩形平板状とし、ワーク支持部材３の長手方向に沿い間隔をおいて直線状に固着する。固着の方法は、磁性体を直接、接着剤を用いて固着する方法、或いは磁性体４８に取付片を取り付け、その取付片を介して間接的に固着する等、何れでもよい。磁性体４８を間隔をおいて取り付けたのは、ワーク支持部材３が折り返し部材を通過する時、搬送用ベルト２の屈曲に追従して屈曲が確保されるようにするもので、ワーク支持部材の屈曲性が確保されるのであれば短冊状の金属製薄板でもよい。 On the other hand, on a substantially center line in the width direction of the work support member 3, a magnetic body (for example, an iron plate) 48 that generates an attracting action with the magnets of the magnet ring 44, the magnet plates 46 and 46 ', and the magnet plate 47, Mounted in a predetermined range (at least approximately 1/3 to 1/2 of the total length of the work support member) from the rear end side (the side opposite to the side engaged with the conveyor belt) to the front end side. It has been.
The magnetic body 48 attached to the work support member 3 is a metal short pipe that can be fitted to a resin shaft 49 that connects the component members (modules) when the work support member 3 is a plastic module belt. Consists of. When the work support member 3 is a single sheet, the magnetic body 48 has a rectangular flat plate shape, and is fixed in a straight line at intervals along the longitudinal direction of the work support member 3. The fixing method may be either a method in which the magnetic body is directly fixed using an adhesive, or an attachment piece is attached to the magnetic body 48 and is indirectly fixed through the attachment piece. The magnetic body 48 is attached at intervals so that when the work support member 3 passes through the folding member, the bending is ensured by following the bending of the conveying belt 2. A strip-shaped metal thin plate may be used as long as flexibility is ensured.

磁石の吸着作用を利用した跳ね返り防止手段Ｘは上記構成により、ワーク支持部材３が分岐仕分けされて終端側の折り返し部を往路側から復路側に通過する時、ワーク支持部材３に取り付けた磁性体４８は搬送用ベルト２に載った状態でマグネットプレート４７上→マグネットリング４４上→マグネットプレート４６’上を、搬送用ベルト２の回動と一緒に移動する。この時、ワーク支持部材３の磁性体４８は、マグネットプレート４７の磁石４７ｂ、マグネットリング４４、及びマグネットプレート４６’の磁石４６ｂとの吸着作用によって搬送用ベルト２の外表面側に引き寄せられ、搬送用ベルト２の外表面に密着積層した状態で折り返し部を通過する。それにより、ワーク支持部材３が往路側から復路側に移動する時、該ワーク支持部材３が反転し跳ね返るのを確実に防止できる（図２０（ａ）、（ｂ）参照）。   The rebound preventing means X using the magnet attracting action has a magnetic body attached to the work supporting member 3 when the work supporting member 3 is branched and passes through the folded portion on the end side from the forward path side to the return path side. 48 moves on the conveyor belt 2 along the rotation of the conveyor belt 2 on the magnet plate 47 → the magnet ring 44 → the magnet plate 46 ′. At this time, the magnetic body 48 of the work support member 3 is attracted to the outer surface side of the conveying belt 2 by the attracting action of the magnet 47b of the magnet plate 47, the magnet ring 44, and the magnet 46b of the magnet plate 46 ′, and is conveyed. Passes through the folded portion in a state of being closely laminated on the outer surface of the belt 2 for use. Thereby, when the work support member 3 moves from the forward path side to the return path side, the work support member 3 can be reliably prevented from being reversed and bounced (see FIGS. 20A and 20B).

又、分岐仕分けされ、往路側から復路側に移動したワーク支持部材３は、始端側の折り返し部を復路側から往路側に通過するが、ワーク支持部材３は原点位置に移動復帰され、原点位置（ベルト幅方向の略中央位置）に配置したマグネットプレート４６上、マグネットリング４４上を通過する。この時、ワーク支持部材３の磁性体４８は、前記終端側の折り返し部を通過する時と同様、マグネットプレート４６の磁石４６ｂ、マグネットリング４４との吸着作用によって搬送用ベルト２の外表面側に引き寄せられ、搬送用ベルト２の外表面に密着積層した状態で折り返し部を通過する。それにより、ワーク支持部材３が復路側から往路側に移動する時、該ワーク支持部材３の搬送方向後側（開放端側）が搬送用ベルト２の外表面から離れて浮き上がり、バタつくのを防止することができる（図１９参照）。尚、始端側の折り返しは、下（復路側）から上（往路側）に移動するため、終端側の折り返しで生じるワーク支持部材３の反転という動作はなく、ワーク支持部材３の搬送方向後側が搬送用ベルト２の外表面から離れ、浮き上がる動作となる。その為に、始端側においては前記動作が発生する範囲内に磁石が配置されている。   Further, the work support member 3 which has been branched and moved from the forward path side to the return path side passes through the folded portion on the starting end side from the return path side to the forward path side, but the work support member 3 is moved and returned to the origin position to return to the origin position. It passes over the magnet plate 46 and the magnet ring 44 arranged at (substantially the center position in the belt width direction). At this time, the magnetic body 48 of the work support member 3 is moved to the outer surface side of the conveying belt 2 by the adsorbing action with the magnet 46b and the magnet ring 44 of the magnet plate 46 in the same manner as when passing through the folded portion on the end side. It is attracted and passes through the folded portion in a state of being closely laminated on the outer surface of the conveying belt 2. Thereby, when the work support member 3 moves from the return path side to the forward path side, the rear side in the transport direction (open end side) of the work support member 3 is lifted away from the outer surface of the transport belt 2 and flutters. This can be prevented (see FIG. 19). In addition, since the return on the start side moves from the lower side (return path side) to the upper side (the forward path side), there is no operation of reversing the work support member 3 caused by the return on the end side, and the rear side in the transport direction of the work support member 3 is It moves away from the outer surface of the conveyor belt 2 and floats. For this purpose, a magnet is arranged in a range where the above operation occurs on the start end side.

終端側の折り返し部におけるワーク支持部材の跳ね返り防止は、前記した磁石の吸着作用によって殆ど問題ないが、支えプレート５０を配置してもよい。その支えプレート５０は、ワーク支持部材３が折り返し部を通過する位置より僅か外側位置に、搬送用ベルト２表面と略平行なるようにコンベヤフレーム１に取り付け、終端側の折り返し部を通過するワーク支持部材３の膨らみを抑えるようにする。その場合、支えプレート５０はワーク支持部材３の幅方向の両側部を支えるよう２個一組で配置するが、ワーク支持部材のサイズ（横幅）に応じて２個一組の間隔を調整し得るように、テールローラの軸方向（搬送用ベルトの幅方向）に移動可能に取り付けてもよい。   Although prevention of the workpiece support member from rebounding at the folded portion on the end side is almost no problem due to the above-described magnet attracting action, a support plate 50 may be disposed. The support plate 50 is attached to the conveyor frame 1 at a position slightly outside the position where the workpiece support member 3 passes through the folded portion so as to be substantially parallel to the surface of the conveyor belt 2 and supports the workpiece passing through the folded portion on the terminal side. The swelling of the member 3 is suppressed. In this case, the support plates 50 are arranged in pairs so as to support both sides in the width direction of the work support member 3, but the distance between the sets can be adjusted according to the size (lateral width) of the work support members. In this way, the tail roller may be attached so as to be movable in the axial direction of the tail roller (width direction of the conveying belt).

跳ね返り防止手段を磁石の吸着作用を利用した上記構成とした場合、ワーク支持部材は装置、部材に接触しないで折り返し部に沿ってスムーズに回動することにより、騒音が発生するのを防止することができる。   When the rebound preventing means is configured as described above using the magnet's attracting action, the work support member smoothly rotates along the folded portion without contacting the device and the member, thereby preventing noise from being generated. Can do.
