Description

【0001】
【発明の属する技術分野】
この発明は、パイプコンベヤべルトの構造にかかわり、更に詳しくは気密性及び密閉性を要求される被搬送物の輸送に適したパイプコンベヤべルトの構造に関するものである。
【0002】
【従来の技術】
一般に、パイプコンベヤのシステムとしては、粉状体や小さい固形物等の被運搬物を運搬する場合に、搬送途中において被運搬物がべルトから落下したり、溢れたりするのを防止させるために、べルトをパイプ状に丸めて被運搬物を包み込むようにして輸送するシステムである。
【0003】
そして、その構成としては、例えば、図4〜図6に示すように、駆動プ−リ1と従動プ−リ2とに上面ゴム層3aと下面ゴム層3bとの間に芯体帆布4を埋設したエンドレス状のべルト5を掛回し、前記駆動プ−リ1と従動プ−リ2との間に、べルト5をパイプ状に丸めて搬送ガイドするための複数のガイドローラ6と、複数の保形ローラ7aを備えた支持板7とを所定の間隔で配設してある。
【0004】
前記支持板7には、図4に示すようにべルト5のキャリア側X(進行方向)が挿通する貫通穴8aと、リターン側Y(戻り側)のべルト5が挿通する貫通穴8bとが形成され、この貫通穴8a,8bの周囲には、べルト5をパイプ状に保持させるための前記複数本(この従来例では6本)の保形ローラ7aが回転自在に配設されている。
【0005】
そして、被運搬物Wの投入は、キャリア側Xの従動プ−リ2側で行われ、また被運搬物Wの排出は、べルト5がキャリア側Xからリターン側Yに反転する駆動プ−リ1側で行われている。
【0006】
前記パイプ状に丸められたべルト5は、図4及び図5に示すように、キャリア側Xにおいて貫通穴8aの上部側で一方のべルト側縁部の外包側内表面5aに他方のベルト側縁部の内包側外表面5bが重ね合わされてパイプ状に構成され、またリターン側Yでは貫通穴8bの下部側において一方のベルト側縁部の外包側内表面5aに内包側外表面5bが重ね合わされてパイプ状に構成され、そしてリータン側Yでは、べルト5の表面に付着した被運搬物Wが下方に落下して周囲を汚すことがないように配慮されている。
【0007】
【発明が解決しようとする課題】
ところで、近年、上記のようなパイプコンベヤにおいて、気密性,密閉性が要求される被運搬物(例えば、粉塵を発生し易い粉体物質や気化しやすい化学物質等)を搬送するためのパイプコンベヤが要求されてきた。
【0008】
然しながら、上記のような従来のパイプコンベヤでは、図5に示すように、べルト5をパイプ状に丸めて被運搬物Wを包み込むようにした構成であって、べルト5の幅方向の両側縁部5x,5yを相互に重ね合わせたものである。
【0009】
即ち、べルト5の幅方向の両側縁部5x,5yを相互に重ね合わせた重合部9の外包側内表面5aと内包側外表面5bとの重ね合わせ面は、べルト5の拡開しようとする弾性力により当接させた簡単な構成であるために、運搬中にべルト5のローリングや旋回時等にべルト5の幅方向の端末重合部から被運搬物Wの一部がこぼれると言う問題があり、上記のような気密性,密閉性が要求される被運搬物Wを搬送するには、必ずしも適切なパイプコンベヤの構成とはなっていなかった。
【0010】
この発明は、かかる従来の問題点に着目して案出されたもので、べルトをパイプ状に丸めた際に、べルト内を気密状態に保持できるように構成することで、既存設備を利用しつつ、被運搬物の飛散や洩れ等を有効に防止出来るパイプコンベヤべルトの構造を提供することを目的とするものである。
【0011】
【課題を解決するための手段】
この発明は、上記目的を達成するため、べルトの幅方向の両側縁部の重合部に、べルトの長手方向に沿って互いに磁着する磁性体を埋設したことを要旨とするものである。
【0012】
前記磁性体を、少なくともべルトの幅方向の両側縁部の重合部の幅に埋設し、またこの磁性体を、べルトの幅方向の両側縁部の少なくとも外包側内表面と内包側外表面との接合面近傍に埋設するものである。
【0013】
また、前記べルトの幅方向の両側縁部の重合部に磁性体ゴムを埋設したり、または固体状の磁性体を所定の間隔で埋設するものである。
【0014】
このように、べルトの両側縁部の重合部に、べルトの長手方向に沿って磁性体を埋設し、べルトの両側縁部の重合部が互いに磁着するように構成することで、べルト内を気密状態に保持させ、これにより被運搬物の輸送時に搬送時に被運搬物が飛散したり、洩れる等の不具合を防止でき、また従来の設備を有効に利用出来ることからコストダウンも図ることが出来るものである。
【0015】
【発明の実施の形態】
以下、添付図面に基づきこの発明の実施の形態を説明する。
【0016】
なお、従来例と同一構成要素は、同一符号を付して説明は省略する。
【0017】
図1は、この発明を実施したパイプコンベヤのキャリア側におけるべルトの幅方向の両側縁部の重合部の一部拡大正面図、図2は一方のべルトの側縁部の内包側端末部と他方のベルトの幅方向の側縁部の外包側端末部との断面図を示し、5はパイプコンベヤを構成するキャリア側Xのべルト、7aはキャリア側Xの保形ローラ、4はべルト5の上面ゴム層3aと下面ゴム層3bとの間に埋設された芯体帆布を示し、べルト5の幅方向の両側縁部5x,5yは、最上部に位置決めする保形ローラ7aの位置で相互に重ね合わせられて重合部9を構成している。
【0018】
この発明の実施形態では、べルト5の幅方向の両側縁部5x,5yの重合部9に、べルト5の長手方向に沿って互いに磁着する磁性体10を埋設して構成してある。
【0019】
前記重合部9に埋設する磁性体10は、この実施形態では、磁性体ゴムを使用しているが、図3に示すように、固体状の磁性体11を所定の間隔でべルト5の長手方向に沿って埋設することも可能である。
【0020】
前記磁性体10及び11の埋設範囲は、埋設する磁性体の種類(磁着力の強弱)に限定されず、少なくともべルト5の幅方向の両側縁部5x,5yの重合部9の幅Hに埋設する。具体的には、べルト5のべルト幅100に対して好ましくは片側で5〜30%の範囲、更に好ましくは5〜20%の範囲で埋設する。
【0021】
その理由として、5%未満ではコンベヤベルトの重合の際に、両側縁部の磁性体の埋設部分同士がうまく重合せず、磁着部分の面積減少により気密性を保つことが出来ない。また30%超では、コンベヤベルトの重合の際に、両側縁部の磁性体の埋設部分同士がうまく重合しない事は起こり難いが、パイプの中空内部の容積が狭くなり、運搬効率が低下すると言う問題があるからである。
【0022】
また磁性体10,11は、磁着力を適正に保つには、べルト5の幅方向の両側縁部5x,5yの少なくとも外包側内表面5aと内包側外表面5bとの接合面近傍に埋設するのが望ましい。
【0023】
このように、べルト5の幅方向の両側縁部5x,5yの重合部9に、べルト5の長手方向に沿って磁性体10を埋設し、べルト5の幅方向の両側縁部5x,5yの重合部9が互いに磁着するように構成することで、べルト5内を気密状態に保持させ、これにより被運搬物Wの運搬時に被運搬物が飛散したり、洩れる等の不具合を防止できる。
【0024】
【発明の効果】
この発明は、上記のようにべルトの幅方向の両側縁部の重合部に、べルトの長手方向に沿って互いに磁着する磁性体を埋設したので、被運搬物の内包する気密性を向上させることが出来る結果、運搬時に被運搬物が飛散したり、洩れる等の不具合を防止でき、また既存設備を有効に利用することが出来るので、設備費用も高くならずに、簡単な構成で被運搬物を安全に運搬することが出来る効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure of a pipe conveyor belt, and more particularly to a structure of a pipe conveyor belt suitable for transporting a conveyed object requiring hermeticity and airtightness.
[0002]
[Prior art]
In general, a pipe conveyor system is used to prevent a conveyed object from falling off or overflowing from the belt during conveyance when conveying conveyed objects such as powders and small solids. This is a system in which the belt is rolled into a pipe shape so as to wrap the transported object and transport it.
[0003]
As a configuration, for example, as shown in FIGS. 4 to 6, the core body canvas 4 is provided between the upper rubber layer 3 a and the lower rubber layer 3 b between the driving pulley 1 and the driven pulley 2. A plurality of guide rollers 6 for rolling the embedded endless belt 5 between the driving pulley 1 and the driven pulley 2 for rolling and conveying the belt 5 in a pipe shape; A support plate 7 having a plurality of shape retaining rollers 7a is arranged at a predetermined interval.
[0004]
As shown in FIG. 4, the support plate 7 has a through hole 8a through which the carrier side X (traveling direction) of the belt 5 is inserted, and a through hole 8b through which the belt 5 on the return side Y (return side) is inserted. Around the through holes 8a and 8b, a plurality of (six in this conventional example) shape retaining rollers 7a for holding the belt 5 in a pipe shape are rotatably arranged. I have.
[0005]
The loading of the transported object W is performed by the driven pulley 2 on the carrier side X, and the discharging of the transported object W is performed by the driving pulley in which the belt 5 reverses from the carrier side X to the return side Y. This is being done on the side of Re1.
[0006]
As shown in FIGS. 4 and 5, the belt 5 which has been rounded into a pipe shape is provided on the carrier side X at the upper side of the through hole 8a and on the outer side inner surface 5a of one belt side edge at the other belt side. On the return side Y, the inner outer surface 5b is overlapped with the outer inner surface 5a of one belt side edge at the lower side of the through hole 8b. Thus, on the return side Y, care is taken so that the conveyed object W attached to the surface of the belt 5 does not fall downward and contaminate the surroundings.
[0007]
[Problems to be solved by the invention]
By the way, in recent years, in a pipe conveyor as described above, a pipe conveyor for transporting a conveyed material (for example, a powdery substance that easily generates dust or a chemical substance that easily vaporizes) that is required to be airtight and airtight. Has been required.
[0008]
However, in the conventional pipe conveyor as described above, as shown in FIG. 5, the belt 5 is rolled into a pipe shape so as to wrap the transported object W, and both sides in the width direction of the belt 5 are provided. The edges 5x and 5y are superimposed on each other.
[0009]
That is, the overlapping surface of the outer side surface 5a and the inner side surface 5b of the overlapping portion 9 where the both side edges 5x and 5y in the width direction of the belt 5 are overlapped with each other is to be expanded. Due to the simple configuration of the contact caused by the elastic force, a part of the transported object W is spilled from the overlapped portion in the width direction of the belt 5 during rolling or turning of the belt 5 during transportation. However, there is a problem that the pipe conveyor is not always suitable for transporting the transported object W requiring the above-described airtightness and airtightness.
[0010]
The present invention has been devised in view of such a conventional problem.When the belt is rolled into a pipe shape, the existing equipment is configured by being configured so that the inside of the belt can be kept airtight. It is an object of the present invention to provide a pipe conveyor belt structure that can effectively prevent a transported object from scattering or leaking while being used.
[0011]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a feature in that magnetic members which are magnetically attached to each other along the longitudinal direction of the belt are embedded in overlapping portions of both side edges in the width direction of the belt. .
[0012]
The magnetic material is embedded in at least the width of the overlapped portion of both sides in the width direction of the belt. And buried in the vicinity of the joint surface with.
[0013]
Further, a magnetic rubber is buried in the overlapping portion on both side edges in the width direction of the belt, or a solid magnetic material is buried at a predetermined interval.
[0014]
In this way, by burying a magnetic material along the longitudinal direction of the belt in the overlapping portion of both sides of the belt, by configuring the overlapping portions of both sides of the belt to be magnetically attached to each other, By keeping the inside of the belt airtight, it is possible to prevent problems such as scattered or leaked objects during transportation when transporting objects, and to reduce costs by effectively using existing equipment. It can be planned.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0016]
The same components as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.
[0017]
FIG. 1 is a partially enlarged front view of an overlapped portion of both side edges in the width direction of a belt on a carrier side of a pipe conveyor embodying the present invention, and FIG. 2 is an inner end portion of a side edge of one belt. 5 is a cross-sectional view of a side edge of the other belt in the width direction and an outer wrapping side end portion, wherein 5 is a belt on the carrier side X constituting the pipe conveyor, 7a is a shape retaining roller on the carrier side X, 9 shows a core canvas buried between the upper rubber layer 3a and the lower rubber layer 3b of the belt 5, and both side edges 5x and 5y of the belt 5 in the width direction are formed by the shape-retaining roller 7a positioned at the top. The overlapping portions 9 are superimposed on each other at the positions to constitute the overlapping portion 9.
[0018]
In the embodiment of the present invention, a magnetic body 10 magnetically attached to each other along the longitudinal direction of the belt 5 is buried in the overlapping portion 9 of both side edges 5x and 5y in the width direction of the belt 5. .
[0019]
In this embodiment, the magnetic material 10 embedded in the overlapping portion 9 is made of a magnetic rubber. However, as shown in FIG. It is also possible to bury it along the direction.
[0020]
The embedding range of the magnetic bodies 10 and 11 is not limited to the type of the magnetic body to be embedded (strength of magnetic force) and is at least equal to the width H of the overlapped portion 9 of both side edges 5x and 5y in the width direction of the belt 5. Buried. Specifically, the belt 5 is buried in a range of 5 to 30%, more preferably 5 to 20%, on one side with respect to the belt width 100 of the belt 5.
[0021]
If the content is less than 5%, when the conveyor belt is polymerized, the buried portions of the magnetic material on both side edges do not polymerize well, and the airtightness cannot be maintained due to the reduced area of the magnetically bonded portion. If it exceeds 30%, it is unlikely that the embedded portions of the magnetic material on both side edges will not polymerize well when the conveyor belt is polymerized, but the volume inside the pipe hollow will be narrowed and the transport efficiency will be reduced. Because there is a problem.
[0022]
In order to keep the magnetic force properly, the magnetic bodies 10 and 11 are embedded at least in the vicinity of the joint surface between the outer side inner surface 5a and the inner side outer surface 5b of both side edges 5x and 5y in the width direction of the belt 5. It is desirable to do.
[0023]
In this manner, the magnetic body 10 is embedded along the longitudinal direction of the belt 5 in the overlapped portion 9 of both sides 5x and 5y of the belt 5 in the width direction, and both sides 5x of the belt 5 in the width direction. , 5y are magnetically adhered to each other, so that the inside of the belt 5 is kept in an airtight state, whereby the transported object W is scattered or leaked when the transported object W is transported. Can be prevented.
[0024]
【The invention's effect】
Since the present invention embeds magnetic materials magnetically attached to each other along the longitudinal direction of the belt in the overlapping portions of both side edges in the width direction of the belt as described above, the airtightness of the carried object is included. As a result, it is possible to prevent the transported object from scattering or leaking during transportation, and it is possible to effectively use existing equipment. There is an effect that the transported object can be transported safely.
