Description

【0001】
【発明の属する技術分野】
本発明は、無端体の回転により搬送物を搬送する搬送装置に関する。
【0002】
【従来の技術】
従来、無端体の回転により搬送物を搬送する搬送装置としては、例えば、図4に示す構成のものが知られている。
【0003】
そして、この図4に示す搬送装置1は、搬送方向Cに沿って長手状の細長略矩形に形成された支持面2を有した支持体3を備えている。また、この支持面2の搬送方向Cにおける端部には、略平板状に形成されたエッジ体4が取り付けられている。このエッジ体4の搬送方向Cである外方側に位置する端辺部には、この搬送方向Cに向けて円弧状に突出する円弧部5が形成されている。
【0004】
また、この搬送装置1のエッジ体4には、搬送物が載置される無端体6が、このエッジ体4の円弧部5で折返されて回転可能に掛け渡されている。この無端体6は、回転して搬送物を搬送する際に、支持体3の支持面2にて支持され、さらに、エッジ体4に掛け渡された際における張力により、このエッジ体4の円弧部5にて回転時における搬送方向Cに対する無端体6の蛇行を防止している。
【0005】
【発明が解決しようとする課題】
しかしながら、上記搬送装置1では、回転時における搬送方向Cに対する無端体6の蛇行を防止するために、エッジ体4に円弧部5が形成されているが、このように、エッジ体4に円弧部5を形成しただけでは、この円弧部5により無端体6に張力を付加しているだけであるため、無端体6の蛇行を的確に防止できないという問題を有している。
【0006】
本発明は、このような点に鑑みなされたもので、回転時の無端体の蛇行を的確に防止できる搬送装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
請求項1記載の搬送装置は、搬送方向に交差する方向の両端部に、この搬送方向に沿った成分を有してそれぞれ突設された一対の突片を備えた平板状のエッジ体と、このエッジ体の一対の突片間にこのエッジ体で折返されて回転可能に掛け渡され、搬送物が載置される無端体の搬送ベルトと、搬送方向に沿った少なくとも前記搬送ベルトの一部を支持する平面状の支持面を上面側に有し、前記エッジ体が搬送方向の端部に設けられた支持体とを具備し、前記突片は、前記搬送ベルトの接する部分から搬送方向に沿って徐々に外方に向けて突出するテーパ状に形成され、前記エッジ体は、前記突片間の距離の最も狭い距離が前記搬送ベルトの幅寸法と等しく形成されているものである。
【0008】
そして、この構成では、搬送方向に沿った成分を有する一対の突片をエッジ体の搬送方向に交差する方向の両端部にそれぞれ突設し、搬送物が載置される無端体の搬送ベルトをエッジ体の一対の突片間にこのエッジ体で折返して回転可能に掛け渡すことにより、搬送ベルト回転時にこの搬送ベルトが搬送方向に対して蛇行した状態で、エッジ体の一対の突片によって搬送ベルトの移動が規制され、この搬送ベルトの蛇行を的確に防止する。また、支持体の搬送方向における端部にエッジ体を設け、このエッジ体に掛け渡した搬送ベルトの少なくとも一部を支持体の支持面が支持するため、搬送の際に搬送ベルトに載置した搬送物を間接的に支持面が支持するので、搬送物を搬送方向に沿って的確に搬送する。さらに、搬送ベルトを折返して回転可能に掛け渡したエッジ体の一対の突片を、搬送ベルトの接する部分から搬送方向に沿って徐々に外方に向けて突出するテーパ状に形成することにより、搬送方向に対して搬送ベルトが蛇行した状態で、この搬送ベルトの蛇行の大きさに比例した復元力が搬送ベルトに働く。このため、回転時における搬送方向に対する搬送ベルトの蛇行をより的確に防止する。また、エッジ体の突片間の距離の最も狭い距離と等しい幅寸法の搬送ベルトを、エッジ体の一対の突片間に折返して回転可能に掛け渡すことにより、搬送ベルトの移動を規制する幅が搬送ベルトの幅と等しくなるため、搬送ベルトの蛇行する量が小さくなり、搬送ベルトの蛇行をより的確に防止する。
【0009】
請求項2記載の搬送装置は、請求項1記載の搬送装置において、エッジ体の上面側に位置する表面部が、支持体の支持面に対して面一となるように形成されているものである。
【0010】
【発明の実施の形態】
以下、本発明の搬送装置の一実施の形態の構成を図1ないし図3を参照して説明する。
【0011】
図1ないし図3において、11a ,11b は一対のフレームで、これら一対のフレーム11a ,11b は、水平方向に長手方向を有し、互いに平行に離間対向して位置した状態で、図示しない支持脚体にて支持されている。これら一対のフレーム11a ,11b は、例えば金属素材などにて細長平板状に形成されている。また、これら一対のフレーム11a ,11b 間には、水平方向に長手方向、すなわち搬送方向Cを有する平面視細長略矩形の支持体12が掛け渡された状態で取り付けられている。この支持体12は、例えば金属素材にて形成されており、また、この支持体12の上面側に位置する表面部には、平板状の支持面13が形成されている。
【0012】
そして、支持体12の搬送方向Cに対する両端部には、例えばステンレスなどの金属素材にて平板状に成形された一対のエッジ体としてのエッジプレート14a ,14b がそれぞれ取り付けられている。これら一対のエッジプレート14a ,14b は、支持体12に対して図示しない皿ボルトなどが用いられて位置決め固定された後、接着剤などが用いられて固着されている。
【0013】
また、これら一対のエッジプレート14a ,14b の支持体12の支持面13に取り付けられた状態で搬送方向Cと交差する、例えば直交する方向の両端部には、この搬送方向Cに沿った成分を有する方向に向けて突出する突片15a ,15b ,15c ,15d がそれぞれ一体的に形成されている。これら突片15a ,15b ,15c ,15d は、エッジプレート14a ,14b の搬送方向Cに沿ってこの搬送方向Cに交差する方向に向かうに連れて徐々に外方に向けて突出するテーパ状にそれぞれ形成されている。
【0014】
さらに、一対のエッジプレート14a ,14b の上面側に位置する表面部16a ,16b は、これら各エッジプレート14a ,14b を支持体12の支持面13に取り付けた状態で、この支持面13に対して面一となるように形成されている。この表面部16a ,16b は、例えば酸などが用いられて摺動抵抗が少なくなるように研磨されている。ここで、一対のエッジプレート14a ,14b は、エッジプレート14a が有する突片15a ,15b と、エッジプレート14b が有する突片15c ,15d とを互いに離れ合う方向に向けて平行に離間対向して、支持体12の搬送方向Cの両端部に取り付けられている。
【0015】
そして、支持体12の搬送方向Cの両端部に取り付けられた一対のエッジプレート14a ,14b は、一対のフレーム11a ,11b に対して、一対のフレーム片17a ,17b ,17c ,17d にて、例えば各5本のねじ体18が用いられてそれぞれ固着されている。さらに、エッジプレート14a ,14b の下方側には、略円筒状に成形されたローラ体19が一対のフレーム片17a ,17b 間に搬送方向Cに向けて回転可能に掛け渡されている。
【0016】
さらに、エッジプレート14a の一対の突片15a ,15b 間と、エッジプレート14b の一対の突片15c ,15d 間との間には、弾性を有する素材にて略環状に成形された無端体としての搬送ベルト21が、これら一対のエッジプレート14a ,14b で折返されて回転可能に掛け渡されている。この搬送ベルト21は、ローラ体19の下方を通過するように掛け渡されており、掛け渡された際における搬送ベルト21の張力によりローラ体19が搬送ベルト21の回転時に回転する。また、この搬送ベルト21は、この搬送ベルト21上に載置された搬送物を搬送する際に、支持体12の支持面13に支持されている。
【0017】
ここで、突片15a ,15b ,15c ,15d は、搬送ベルト21が掛け渡された状態で、この搬送ベルト21と接する部分から搬送方向Cに沿って徐々に突出するテーパ状にそれぞれ形成されている。
【0018】
また、搬送ベルト21の幅寸法は、エッジプレート14a の突片15a ,15b 間の距離と、エッジプレート14b の突片15c ,15d 間の距離との最も狭い距離と等しく形成されている。さらに、この搬送ベルト21は、この搬送ベルト21上に載置された搬送物をこの搬送ベルト21の回転により搬送方向Cに向けて搬送する。また、この搬送ベルト21は、回転にて搬送物を搬送する際に、エッジプレート14a の突片15a ,15b 間と、エッジプレート14b の突片15c ,15d 間とをそれぞれ摺動する。
【0019】
そして、搬送ベルト21には、この搬送ベルト21を送り出して回転させる図示しない駆動手段が取り付けられている。この駆動手段は、支持体12の下面側に配設されており、例えば、図示しない駆動モータの起動にて図示しないローラが回転し、このローラの回転により搬送ベルト21が回転するように形成されている。
【0020】
次に、上記一実施の形態の作用について説明する。
【0021】
図示しない駆動手段を起動すると、搬送ベルト21が搬送方向Cで回転する。
【0022】
この状態で、搬送ベルト21の搬送方向Cの搬送始端側に搬送物を載置すると、この搬送ベルト21の回転にて搬送物をこの搬送方向Cの搬送終端側へと搬送する。
【0023】
このとき、搬送ベルト21は、エッジプレート14a の突片15a ,15b 間と、エッジプレート14b の突片15c ,15d 間とをそれぞれ摺動するとともに、支持体12の支持面13にて支持されて搬送物を搬送し、さらに、ローラ体19に支持されてこのローラ体19を回転している。
【0024】
上述したように、上記一実施の形態では、搬送物を搬送する際に搬送ベルト21を回転する。このとき、この搬送ベルト21が搬送方向Cに対して蛇行する場合が想定されるが、エッジプレート14a の突片15a ,15c 間およびエッジプレート14b の突片15b ,15d 間を搬送ベルト21が摺動して通過する。このため、突片15a ,15b ,15c ,15d により、この搬送ベルト21が蛇行した状態で、この搬送ベルト21の蛇行した方向側に位置する側部が拡幅して、この側部に復元力および張力が働く。そして、この復元力および張力により搬送ベルト21の移動を規制するので、エッジプレート14a ,14b の外側部が円弧状に形成されている場合に比べると、搬送ベルト21を掛け渡した際における張力以外に復元力にて搬送ベルト21の蛇行を防止するため、搬送ベルト21の蛇行を的確に防止できる。
【0025】
このとき、特に、各突片15a ,15b ,15c ,15d が搬送方向Cに沿って除々に外方に向けて突出するテーパ状に形成されているため、搬送方向Cに対して搬送ベルト21が蛇行した状態では、この搬送ベルト21の蛇行の大きさに比例した復元力が搬送ベルト21に働く。このため、搬送方向Cに対する搬送ベルト21の蛇行をより的確に防止できる。
【0026】
また、搬送ベルト21の幅寸法が、エッジプレート14a の突片15a ,15b 間と、エッジプレート14b の突片15c ,15d 間との距離との最も狭い距離と等しく形成されているため、搬送ベルト21の移動を規制する幅が搬送ベルト21の幅と等しい。このため、搬送方向Cに対して搬送ベルト21が若干蛇行した状態であっても、各エッジプレート14a ,14b の突片15a ,15b ,15c ,15d により搬送ベルト21の蛇行した側に位置する一側部が若干拡幅し、この拡幅により搬送ベルト21の一側部に復元力および張力を的確に付加できる。よって、搬送方向Cに対する搬送ベルト21の蛇行をさらに的確に防止できる。
【0027】
さらに、搬送ベルト21上に載置された搬送物は、支持体12の支持面13に支持されてこの搬送ベルト21の回転にて搬送方向Cに向けて搬送できるので、比較的小さい搬送物および重い搬送物であっても、的確に搬送できる。
【0028】
なお、上記一実施の形態では、エッジプレート14a に突片15a ,15b が形成され、さらにエッジプレート14b にも同様に突片15c ,15d が形成された構成について説明したが、このような構成に限定されることはなく、少なくともいずれか一方のエッジプレート14a ,14bに一対の突片15a ,15b ,15c ,15d が形成されていれば、搬送方向Cに対する搬送ベルト21の蛇行を防止できる。
【0029】
また、上記一実施の形態では、支持体12の搬送方向Cの両端部にエッジプレート14a ,14b がそれぞれ取り付けられ、これらエッジプレート14a ,14b を搬送ベルト21が摺動する、いわゆるナイフエッジ型のベルトコンベヤについて説明した。このため、このベルトコンベヤの搬送方向Cにおける搬送終端側に、別のベルトコンベヤの搬送方向Cにおける搬送始端側を、近接させて向かい合わせた状態で配設することにより、比較的小さな搬送物であっても、これらベルトコンベヤ間を的確に乗り越えさせて搬送することができる。
【0030】
【発明の効果】
本発明によれば、エッジ体の一対の突片間にこのエッジ体で折返して回転可能に無端体の搬送ベルトを掛け渡すことにより、回転時に搬送ベルトが搬送方向に対して蛇行した状態で、エッジ体の各突片によって搬送ベルトの移動を規制するので、搬送ベルトの蛇行を的確に防止できる。また、支持体の搬送方向の端部にエッジ体を設けたことにより、支持面が搬送ベルトの少なくとも一部を支持するので、搬送ベルトに載置された搬送物を搬送方向に沿って的確に搬送できる。さらに、各突片を搬送ベルトの接する部分から搬送方向に沿って徐々に外方に向けて突出するテーパ状に形成したことにより、搬送方向に対して搬送ベルトが蛇行した状態で、この蛇行の大きさに比例した復元力が搬送ベルトに働くので、回転時における搬送ベルトの蛇行をより的確に防止できる。また、エッジ体の突片間の距離の最も狭い距離と等しい幅寸法の搬送ベルトを、突片間に折返して回転可能に掛け渡すことにより、搬送ベルトの移動を規制する幅が搬送ベルトの幅と等しくなるため、搬送ベルトの蛇行量を小さくでき、この搬送ベルトの蛇行をより的確に防止できる。

As shown in FIG. Further, an edge body 4 formed in a substantially flat plate shape is attached to an end portion of the support surface 2 in the transport direction C. An arc portion 5 that protrudes in an arc shape toward the transport direction C is formed at an end portion located on the outer side in the transport direction C of the edge body 4.
[0004]
In addition, an endless body 6 on which a conveyed product is placed is folded around an arc portion 5 of the edge body 4 so as to be rotatable. The endless body 6 is supported by the support surface 2 of the support body 3 when rotating and transporting the transported object, and further, the arc of the edge body 4 is caused by the tension applied to the edge body 4. The portion 5 prevents the endless body 6 from meandering with respect to the conveyance direction C during rotation.
[0005]
[Problems to be solved by the invention]
However, in the transport device 1, the arc body 5 is formed on the edge body 4 in order to prevent the endless body 6 from meandering in the transport direction C during rotation. If only 5 is formed, only the tension is applied to the endless body 6 by the arc portion 5, so that the meandering of the endless body 6 cannot be prevented accurately.
[0006]
This invention is made in view of such a point, and it aims at providing the conveying apparatus which can prevent the meandering of an endless body at the time of rotation exactly.
[0007]
[Means for Solving the Problems]
Conveying apparatus comprising, at both ends in the direction orthogonal to the conveying direction, a flat plate-like edge member having a pair of projecting pieces projecting respectively have a component along this conveying direction An endless transport belt that is folded back and rotatably supported by the edge body between the pair of projecting pieces of the edge body, and at least one of the transport belts along the transport direction. A flat support surface for supporting the portion on the upper surface side, and the edge body is provided with a support body provided at an end portion in the transport direction, and the projecting piece is transported in a transport direction from a portion in contact with the transport belt is tapered protruding gradually outward along the edges are those that the narrowest distance of the distance between the projecting pieces is equal properly formed and the width of the conveyor belt .
[0008]
In this configuration, a pair of projecting pieces having components along the transport direction are respectively provided at both ends in a direction intersecting the transport direction of the edge body, and an endless transport belt on which the transported object is placed is provided. By folding the edge body between the pair of protrusions of the edge body so as to be rotatable, the conveyance belt is meandering with respect to the conveyance direction when the conveyance belt is rotated, and is conveyed by the pair of protrusions of the edge body. The movement of the belt is restricted, and the meandering of the conveyor belt is accurately prevented. Further, an edge body is provided at the end of the support in the transport direction, and the support surface of the support supports at least a part of the transport belt spanned over the edge body. Therefore, the support body is placed on the transport belt during transport. Since a support surface supports a conveyed product indirectly, a conveyed product is conveyed accurately along a conveyance direction. Furthermore, by forming a pair of projecting pieces of the edge body that folds around the conveyor belt so as to be able to rotate, it is formed into a tapered shape that gradually protrudes outward along the conveyance direction from the portion in contact with the conveyance belt, In a state where the conveying belt meanders in the conveying direction, a restoring force proportional to the magnitude of the meandering of the conveying belt acts on the conveying belt. For this reason, the meandering of the conveyance belt with respect to the conveyance direction during rotation is more accurately prevented. Further, the conveyor belt of the narrowest distance and equal Shii width of the distance between the projecting pieces of the edge member, by passing rotatably hung folded between a pair of projecting pieces of the edge member, for restricting the movement of the conveyor belt the width is equal properly the width of the conveyor belt, the amount of meandering of the conveyor belt is reduced, more accurately prevent the meandering of the conveyor belt.
[0009]
According to a second aspect of the present invention, in the conveying device according to the first aspect, the surface portion located on the upper surface side of the edge body is formed to be flush with the supporting surface of the supporting body. is there.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration of an embodiment of the transfer apparatus of the present invention will be described with reference to FIGS. 1 to 3.
[0011]
1 to 3, reference numerals 11a and 11b denote a pair of frames. The pair of frames 11a and 11b have a longitudinal direction in the horizontal direction and are spaced apart from and parallel to each other, and are not shown. Supported by the body. The pair of frames 11a and 11b are formed in an elongated flat plate shape, for example, with a metal material. Further, between the pair of frames 11a and 11b, a support body 12 having an elongated rectangular shape in plan view having a longitudinal direction in the horizontal direction, that is, a conveying direction C, is mounted. The support 12 is made of, for example, a metal material, and a flat support surface 13 is formed on a surface portion located on the upper surface side of the support 12.
[0012]
Then, the both end portions in the conveyance direction C of the support 12, for example, similar metallic material such as stainless steel flat plate-like molded a pair of edge plates 14a as an edge member, 14b are respectively attached. The pair of edge plates 14a and 14b are fixedly fixed to the support 12 using a countersunk bolt or the like (not shown) and then an adhesive or the like.
[0013]
In addition, a component along the transport direction C is applied to both ends of the pair of edge plates 14a and 14b that are attached to the support surface 13 of the support 12 and intersect the transport direction C, for example, in the orthogonal direction. Projection pieces 15a, 15b, 15c, and 15d projecting in the direction in which they are provided are integrally formed. These projecting pieces 15a, 15b, 15c and 15d are tapered so as to gradually protrude outward along the transport direction C of the edge plates 14a and 14b in the direction crossing the transport direction C, respectively. Is formed.
[0014]
Furthermore, the surface portions 16a and 16b located on the upper surface side of the pair of edge plates 14a and 14b are attached to the support surface 13 in a state where the edge plates 14a and 14b are attached to the support surface 13 of the support body 12. It is formed to be flush with each other. The surface portions 16a and 16b are polished so as to reduce sliding resistance using, for example, an acid. Here, the pair of edge plates 14a and 14b are arranged so that the protruding pieces 15a and 15b included in the edge plate 14a and the protruding pieces 15c and 15d included in the edge plate 14b are spaced apart from each other in parallel. The support 12 is attached to both ends in the transport direction C.
[0015]
A pair of edge plates 14a, 14b attached to both ends of the support 12 in the transport direction C is a pair of frame pieces 17a, 17b, 17c, 17d with respect to the pair of frames 11a, 11b. Each of the five screw bodies 18 is used and fixed. Further, on the lower side of the edge plates 14a and 14b, a roller body 19 formed in a substantially cylindrical shape is suspended between a pair of frame pieces 17a and 17b so as to be rotatable in the conveying direction C.
[0016]
Further, between the pair of projecting pieces 15a and 15b of the edge plate 14a and between the pair of projecting pieces 15c and 15d of the edge plate 14b, an endless body formed in a substantially annular shape with an elastic material is used. The conveyor belt 21 is folded around the pair of edge plates 14a and 14b and is rotatably supported. The conveyor belt 21 is stretched so as to pass below the roller body 19, and the roller body 19 rotates when the conveyor belt 21 rotates due to the tension of the conveyor belt 21 when the conveyor belt 21 is stretched. Further, the transport belt 21 is supported on the support surface 13 of the support 12 when transporting a transported object placed on the transport belt 21.
[0017]
Here, each of the projecting pieces 15a, 15b, 15c, 15d is formed in a taper shape that gradually protrudes along the conveying direction C from a portion in contact with the conveying belt 21 in a state where the conveying belt 21 is stretched. Yes.
[0018]
Also, the width of the conveyor belt 21, the projecting pieces 15a of the edge plate 14a, the distance between 15b, protrusion 15c of the edge plate 14b, and is narrowest distance and equal properly formed and the distance between 15d. Further, the transport belt 21 transports the transported object placed on the transport belt 21 in the transport direction C by the rotation of the transport belt 21. Further, when the transport belt 21 transports a transported object by rotation, the transport belt 21 slides between the projecting pieces 15a and 15b of the edge plate 14a and between the projecting pieces 15c and 15d of the edge plate 14b.
[0019]
The conveyor belt 21 is provided with a driving means (not shown) that feeds and rotates the conveyor belt 21. This driving means is disposed on the lower surface side of the support 12 and is formed, for example, such that a roller (not shown) rotates when a driving motor (not shown) is started, and the conveyor belt 21 rotates by the rotation of this roller. ing.
[0020]
Next, the operation of the above embodiment will be described.
[0021]
When a driving unit (not shown) is activated, the transport belt 21 rotates in the transport direction C.
[0022]
In this state, when a transported object is placed on the transport start end side in the transport direction C of the transport belt 21, the transported object is transported to the transport end side in the transport direction C by the rotation of the transport belt 21.
[0023]
At this time, the conveyor belt 21 slides between the protrusions 15a and 15b of the edge plate 14a and between the protrusions 15c and 15d of the edge plate 14b, and is supported by the support surface 13 of the support body 12. The conveyed object is conveyed, and is further supported by the roller body 19 to rotate the roller body 19.
[0024]
As described above, in the above embodiment, the transport belt 21 is rotated when transporting a transported object. At this time, it is assumed that the conveying belt 21 meanders in the conveying direction C. However, the conveying belt 21 slides between the protruding pieces 15a and 15c of the edge plate 14a and between the protruding pieces 15b and 15d of the edge plate 14b. Move and pass. For this reason, the side portions of the conveyor belt 21 located on the meandering direction side are widened by the protrusions 15a, 15b, 15c and 15d in a meandering state, and the restoring force and the side portions are widened. Tension works. Since the movement of the conveyor belt 21 is regulated by this restoring force and tension, the tensions other than the tension when the conveyor belt 21 is stretched are compared with the case where the outer portions of the edge plates 14a, 14b are formed in an arc shape. Further, since the meandering of the conveying belt 21 is prevented by the restoring force, the meandering of the conveying belt 21 can be accurately prevented.
[0025]
At this time, in particular, each of the projecting pieces 15a, 15b, 15c, 15d is formed in a tapered shape that gradually protrudes outward along the transport direction C. In the meandering state, a restoring force proportional to the magnitude of the meandering of the conveyor belt 21 acts on the conveyor belt 21. For this reason, the meandering of the conveyance belt 21 with respect to the conveyance direction C can be prevented more accurately.
[0026]
Further, since the width of the conveyor belt 21, the projecting piece 15a of the edge plate 14a, and between 15b, protrusion 15c of the edge plate 14b, and is narrowest distance and equal properly formed and the distance between the inter-15d, transport etc. arbitrary width for restricting movement of the belt 21 and the width of the conveyor belt 21. For this reason, even if the conveyor belt 21 is slightly meandering with respect to the conveyance direction C, it is located on the meandering side of the conveyor belt 21 by the protruding pieces 15a, 15b, 15c, 15d of the edge plates 14a, 14b. The side portion is slightly widened, and by this widening, restoring force and tension can be accurately applied to one side portion of the conveyor belt 21. Therefore, the meandering of the conveying belt 21 with respect to the conveying direction C can be prevented more accurately.
[0027]
Further, since the transported object placed on the transport belt 21 is supported by the support surface 13 of the support 12 and can be transported in the transport direction C by the rotation of the transport belt 21, relatively small transported objects and Even heavy objects can be conveyed accurately.
[0028]
In the above-described embodiment, the configuration in which the protrusions 15a and 15b are formed on the edge plate 14a and the protrusions 15c and 15d are similarly formed on the edge plate 14b has been described. There is no limitation, and if the pair of projecting pieces 15a, 15b, 15c, 15d is formed on at least one of the edge plates 14a, 14b, the meandering of the transport belt 21 in the transport direction C can be prevented.
[0029]
In the above-described embodiment, edge plates 14a and 14b are attached to both ends of the support 12 in the conveyance direction C, respectively, and the edge belts 14a and 14b slide on the conveyance belt 21, so-called knife edge type. The belt conveyor has been described. For this reason, by arranging the conveying start end side in the conveying direction C of another belt conveyor close to each other on the conveying end side in the conveying direction C of this belt conveyor, Even in such a case, the belt conveyors can be accurately passed over and conveyed.

【The invention's effect】
According to the present invention, by folding the endless transport belt between the pair of protrusions of the edge body and rotating the endless transport belt, the transport belt meanders in the transport direction during rotation. Since the movement of the conveying belt is regulated by the protruding pieces of the edge body, the meandering of the conveying belt can be accurately prevented. In addition, since the edge body is provided at the end of the support in the transport direction, the support surface supports at least a part of the transport belt, so that the transported object placed on the transport belt can be accurately aligned along the transport direction. Can be transported. Further, each of the protruding pieces is formed in a tapered shape that gradually protrudes outward along the conveying direction from the portion where the conveying belt contacts, so that the conveying belt meanders in the conveying direction. Since a restoring force proportional to the size acts on the conveyor belt, meandering of the conveyor belt during rotation can be prevented more accurately. Further, the conveyor belt of the narrowest distance and equal Shii width of the distance between the projecting pieces of the edge member, by passing rotatably hung folded between protrusion width for restricting movement of the conveyor belt of the conveyor belt to become width and equal properly, it is possible to reduce the amount of meandering of the conveyor belt, thereby preventing the meandering of the conveyor belt more accurately.
