Description

【０００１】
【発明の属する技術分野】
本発明は、ベルト背面に突起が設けられた突起付きベルトに関する。
【０００２】
【従来の技術】
ベルト背面に突起が設けられた突起付きベルトが広く用いられている。この突起は、ベルト背面で物品を搬送する場合の物品間の仕切りとなったり、ベルトの走行位置を検知するセンサーを作動させたり、物品を押して移動させたり等する機能を果たすものである。
【０００３】
そして、このような突起は、ゴムベルトの場合ではベルト背面の研削加工によって形成され、また、注型タイプの熱硬化性ウレタンベルトの場合ではかかる突起が形成されるようにされた注型用金型にウレタンプレポリマー組成物を注入して硬化させることによって形成される。すなわち、いずれの場合にも突起はベルト本体と一体に設けられているものである。
【０００４】
ところで、突起が他の物品と接触する搬送等の用途においては、突起がベルト長さ方向に外力を受けて損傷を受けるという問題がある。これに対し、突起のベルト長さ方向の厚さを厚くして突起の耐荷重性を向上させる、という解決手段が考えられる。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記の如く突起はベルト本体と一体に設けられているので、突起の厚さを厚くすると、突起部分のベルト剛性が大きいものとなってしまい、小径のプーリにはベルトを適正に巻き掛けることができない、という問題がある。特に、ベルト本体が歯付ベルトである場合、ベルト歯のプーリ溝への噛み合い不良を起こす可能性がある。
【０００６】
また、注型タイプの熱硬化性ウレタンベルトの場合、ベルト背面に大きい突起が形成されると注型用金型からの脱型が困難となって加工性が悪い、という問題もある。
【０００７】
本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、ベルト背面の突起の強度を高めるために突起のベルト長さ方向の厚さを厚くした場合でも小径のプーリに適正な巻き掛けが可能となり、且つ注型タイプの熱硬化性ウレタンベルトの場合でも加工性に優れる突起付きベルトを提供することにある。
【０００８】
【課題を解決するための手段】
本発明は、突起付きベルトにおいて、ベルト背面に板状支持部を立設し、これを覆うように突起部材を設け、この突起部材を板状支持部にのみ固定することとしたものである。
【０００９】
具体的には、本出願の発明は、ベルト背面に突起が設けられた突起付きベルトであって、
ベルト背面に一体に設けられ、板面がベルト長さ方向を向くように立設された板状支持部と、
上記板状支持部を覆うように設けられた突起部材とを備え、
上記板状支持部には、その厚さ方向に貫通して両側に突出した状態に棒状部材が取り付けられ、
上記突起部材は、上記棒状部材が取り付けられた上記板状支持部を埋設するように熱可塑性樹脂で形成されていることにより上記板状支持部にのみ固定されていることを特徴とする。
【００１０】
上記の構成によれば、突起をベルト長さ方向に厚くして耐荷重性を向上させても、突起を形成する突起部材は板状支持部にのみ固定されている、すなわち、ベルト背面に固定されていないので、突起によってベルト剛性が高くなるということはなく、小径のプーリにも適正な巻き掛けが可能となる。
【００１１】
また、注型タイプの熱硬化性ウレタンベルトを製造する場合でも、ベルト背面に板状支持部が設けられたベルト本体を成型すればよく、加工性にも優れるものとなる。
【００１２】
さらに、突起が損傷を受けた場合には、突起部材のみの交換による補修をすることができ、突起部材の形成材料の種類によっては摩耗部位または欠損部位にその形成材料を補充する補修も可能となる。
【００１３】
また、棒状部材が板状支持部に、その厚さ方向に貫通して両側に突出した状態に取り付けられているので、突起部材は棒状部材を介して板状支持部に強固に固定されることとなり、突起部材が板状支持部から抜けるのが防止される。加えて、板状支持部を単に突起部材に設けた挿入孔に挿入する場合、またはその挿入孔内で接着剤によって板状支持部に突起部材を接着固定する場合に比べて、固定度のバラツキが少ないものとなる。
【００１４】
【発明の効果】
以上説明したように、本発明によれば、突起をベルト長さ方向に厚くして耐荷重性を向上させても、突起を形成する突起部材は板状支持部にのみ固定されている、すなわち、ベルト背面には固定されていないので、突起によってベルト剛性が高くなるということはなく、小径のプーリにも適正な巻き掛けが可能となる。また、注型タイプの熱硬化性ウレタンベルトを製造する場合でも、ベルト背面に板状支持部が設けられたベルト本体を成型すればよく、加工性にも優れるものとなる。さらに、突起が損傷を受けた場合には、突起部材のみの交換による補修をすることができ、突起部材の形成材料の種類によっては摩耗部位または欠損部位にその形成材料を補充する補修も可能となる。
【００１５】
また、棒状部材が板状支持部に、その厚さ方向に貫通して両側に突出した状態に取り付けられているので、突起部材は棒状部材を介して板状支持部に強固に固定されることとなり、突起部材が板状支持部から抜けるのが防止される。加えて、板状支持部を単に突起部材に設けた挿入孔に挿入する場合、またはその挿入孔内で接着剤によって板状支持部に突起部材を接着固定する場合に比べて、固定度のバラツキが少ないものとなる。
【００１６】
【発明の実施の形態】
本発明の実施形態を図面に基づいて詳細に説明する。
【００１７】
図１は本発明の実施形態に係るベルトＢを示す。このベルトＢは、歯付ベルトの一種であって、内面に所定ピッチの歯部２，２，…を有するポリウレタン組成物からなるベルト本体１を備え、そのベルト本体の各歯部２の底部に沿って抗張体としてのアラミド繊維からなる心線３が埋設されている。
【００１８】
そして、本発明の特徴として、ベルト背面には板面がベルト長さ方向を向いた板状支持部４がベルト本体１と一体に立設されており、また、その板状支持部４には棒状部材としてのステンレス（ＳＵＳ）製ピン５が貫通状態で取り付けられている。さらに、板状支持部４とピン５とを覆うようにアセタール樹脂（ＰＯＭ）製の突起部材６が設けられており、この突起部材６がベルト背面にベルト歯約２つ分の突起を形成している。ここで、突起部材６は、ピン５を介して板状支持部４に固定されることとなるが、突起部材６の底面はベルト背面に固定されていない。
【００１９】
以上の構成の突起付きベルトＢにおいては、突起部材６によって形成された突起はベルト歯約２つ分の厚さを有し、耐荷重性の向上が図られているが、突起部材６は板状支持部４にピン５を介して固定されているだけであり、突起部材６の底面はベルト背面に固定されていないため、突起部材６によってベルト剛性が高くなるということはなく、突起付きベルトＢは小径のプーリにも適正な巻き掛けが可能である。
【００２０】
また、熱硬化性ウレタンの注型加工によって、ベルト背面に板状支持部４が立設されたベルト本体１を成型すればよいので、大型の突起を成型する必要がなく、容易に脱型でき、加工性にも優れている。
【００２１】
さらに、突起が損傷を受けた場合、突起部材６のみを取り除き、下記に示すベルトの製造方法に準じ、新しい突起部材６を設ける補修も可能である。また、突起部材６表面の摩耗または欠損といった軽微な損傷の場合には、突起部材６を取り除くことなく、突起部材６を再度射出金型にセットし、樹脂を射出して摩耗部位または欠損部位に樹脂を補充する補修も可能である。
【００２２】
また、突起部材６は、板状支持部４を貫通した状態で埋設されたピン５によって板状支持部４に固定されているので、突起部材６は強固に板状支持部４に固定されることとなり、突起部材６が板状支持部４から抜けるのが防止される。加えて、板状支持部を単に突起部材に設けた挿入孔に挿入する場合、またはその挿入孔内で接着剤によって板状支持部に突起部材を接着固定する場合に比べて、固定度のバラツキが少ない。
【００２３】
そして、上記突起付きベルトＢは以下のようにして製造される。
【００２４】
＜ベルト本体形成工程＞
ベルト背面に板状支持部が立設された歯付ベルト本体が形成されるようにされた注型用金型にウレタンプレポリマー組成物を注入し、加熱して硬化させる。これによって、板状支持部がベルト背面に一体に立設されたベルト本体が形成されることとなる。なお、注型用金型には上記組成物の注入前に予め心線を緊張状態でセットしておき、ベルトに心線が埋設されるようにしておく。
【００２５】
＜ピン装着工程（棒状部材取付工程）＞
板状支持部の中央部に穴を開け、これに棒状部材としてのステンレス（ＳＵＳ）製ピンを通し、ピンが板状支持部の厚さ方向に貫通して両側に突出した状態に保持された状態とする。
【００２６】
＜射出金型セット工程＞
突起部材を成型するための射出金型内にピンが貫通した板状支持部のみをインサートし、所定位置にセットする。
【００２７】
＜樹脂射出工程（突起部材形成工程）＞
射出金型内に溶融したアセタール樹脂（ＰＯＭ）を射出する。これによって板状支持部にピンが貫通した状態で、それらが樹脂で形成された突起部材に埋設されることとなる。
【００２８】
＜脱型工程＞
射出金型からベルトに取り付けられた突起部材を取り出す。
【００２９】
以上の突起付きベルトの製造方法によれば、板状支持部が熱可塑性樹脂によって形成された突起部材に覆われ、しかも棒状部材が板状支持部を貫通した状態で突起部材に埋設された構成が容易に得られることとなる。
【００３０】
（その他の実施形態）
上記実施形態では、ベルト本体１を歯付ベルトとしたが、これに限定されるものではなく、平ベルト、Ｖベルト等であってもよい。
【００３１】
また、上記実施形態では、ベルト本体１を熱硬化性ポリウレタンで形成したものとしたが、これに限定されるものではなく、ゴムで形成されたものであってもよい。
【００３２】
また、上記実施形態では、棒状部材としてピン５を用いたが、特にこれに限定されるものではなく、ボルト等の棒状のものであればよい。また、棒状部材はステンレス（ＳＵＳ）、砲金材（ＢＳＢＭ）、アルミニウム等の金属製の他、樹脂製等であってもよい。
【００３３】
また、上記実施形態では、板状支持部４に棒状部材としてのピン５を１本だけ取り付けたが、これを複数本取り付けてもよい。このようにすることにより、突起部材の板状支持部への固定がより強固なものとすることができる。
【００３４】
また、上記実施形態では、突起部材６をアセタール樹脂（ＰＯＭ）製としたが、特にこれに限定されるものではなく、ポリアミド樹脂（ＰＡ）、ポリカーボネート樹脂（ＰＣ）、アクリロノトリル−ブタジエン−スチレン樹脂（ＡＢＳ）等であってもよい。
【００３５】
また、上記実施形態では、板状支持部４に貫通したピン５により、突起部材６が板状支持部４に固定された構成としたが、特にこれに限定されるものではなく、例えば板状支持部を挿入できる挿入孔を設けた突起部材を予め形成し、その挿入孔に接着剤を流し込み、それに板状支持部を挿入して接着剤を硬化させる等の構成であってもよい。

BACKGROUND OF THE INVENTION
The present invention relates to a belt with protrusions provided with protrusions on the back surface of the belt.
[0002]
[Prior art]
A belt with a protrusion having a protrusion provided on the back surface of the belt is widely used. This protrusion serves as a partition between articles when the article is conveyed on the back of the belt, activates a sensor for detecting the belt running position, or pushes and moves the article.
[0003]
In the case of a rubber belt, such a protrusion is formed by grinding the back surface of the belt, and in the case of a casting type thermosetting urethane belt, such a protrusion is formed. It is formed by injecting and curing a urethane prepolymer composition. That is, in any case, the protrusion is provided integrally with the belt body.
[0004]
By the way, in applications such as conveyance in which the protrusions come into contact with other articles, there is a problem that the protrusions are damaged by receiving an external force in the belt length direction. On the other hand, there can be considered a solution to increase the load resistance of the protrusion by increasing the thickness of the protrusion in the belt length direction.
[0005]
[Problems to be solved by the invention]
However, since the protrusion is provided integrally with the belt body as described above, increasing the thickness of the protrusion increases the belt rigidity of the protrusion, so that the belt is properly wound around a small-diameter pulley. There is a problem that can not be. In particular, when the belt body is a toothed belt, there is a possibility that the meshing failure of the belt teeth with the pulley groove may occur.
[0006]
In addition, in the case of a casting type thermosetting urethane belt, if a large protrusion is formed on the back surface of the belt, it is difficult to remove from the casting mold, resulting in poor workability.
[0007]
The present invention has been made in view of the above points, and the object of the present invention is to make a pulley with a small diameter even when the thickness of the protrusion in the belt length direction is increased in order to increase the strength of the protrusion on the back surface of the belt. An object of the present invention is to provide a protrusion-provided belt that can be properly wound and is excellent in workability even in the case of a cast-type thermosetting urethane belt.
[0008]
[Means for Solving the Problems]
In the belt with protrusions, the present invention is such that a plate-like support portion is erected on the back surface of the belt, a protrusion member is provided so as to cover it, and the protrusion member is fixed only to the plate-like support portion.
[0009]
Specifically, the invention of the present application is a belt with a protrusion provided with a protrusion on the back surface of the belt,
A plate-like support portion that is integrally provided on the back surface of the belt and is erected so that the plate surface faces the belt length direction;
A projection member provided so as to cover the plate-like support portion,
A rod-like member is attached to the plate-like support portion in a state of penetrating in the thickness direction and protruding to both sides,
The protrusion member is fixed only to the plate-like support portion by being formed of a thermoplastic resin so as to embed the plate-like support portion to which the rod-like member is attached .
[0010]
According to the above configuration, even if the protrusion is thickened in the belt length direction to improve the load resistance, the protrusion member forming the protrusion is fixed only to the plate-like support portion, that is, fixed to the back surface of the belt. As a result, the belt rigidity is not increased by the protrusions, and appropriate winding is possible even on a small-diameter pulley.
[0011]
Further, even when a cast type thermosetting urethane belt is manufactured, a belt main body provided with a plate-like support portion on the back surface of the belt may be molded, and the processability is excellent.
[0012]
In addition, if the projection is damaged, it can be repaired by replacing only the projection member, and depending on the type of projection member forming material, it is also possible to repair by replenishing the forming material to the worn part or defective part Become.
[0013]
Further, since the rod-like member is attached to the plate-like support portion so as to penetrate in the thickness direction and protrude on both sides, the protruding member is firmly fixed to the plate-like support portion via the rod-like member. Thus, the protruding member is prevented from coming off from the plate-like support portion. In addition, when the plate-like support portion is simply inserted into the insertion hole provided in the projection member, or when the projection member is bonded and fixed to the plate-like support portion with an adhesive in the insertion hole, the degree of fixation is different. Will be less.
[0014]
【The invention's effect】
As described above, according to the present invention, even if the protrusion is thickened in the belt length direction to improve the load resistance, the protrusion member that forms the protrusion is fixed only to the plate-like support portion. Since the belt is not fixed to the back surface of the belt, the protrusion does not increase the rigidity of the belt, and it is possible to appropriately wind a pulley having a small diameter. Further, even when a cast type thermosetting urethane belt is manufactured, a belt main body provided with a plate-like support portion on the back surface of the belt may be molded, and the processability is excellent. In addition, if the projection is damaged, it can be repaired by replacing only the projection member, and depending on the type of projection member forming material, it is also possible to repair by replenishing the forming material to the worn part or defective part Become.
[0015]
Further, since the rod-like member is attached to the plate-like support portion so as to penetrate in the thickness direction and protrude on both sides, the protruding member is firmly fixed to the plate-like support portion via the rod-like member. Thus, the protruding member is prevented from coming off from the plate-like support portion. In addition, when the plate-like support portion is simply inserted into the insertion hole provided in the projection member, or when the projection member is bonded and fixed to the plate-like support portion with an adhesive in the insertion hole, the degree of fixation is different. Will be less.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in detail with reference to the drawings.
[0017]
FIG. 1 shows a belt B according to an embodiment of the present invention. The belt B is a kind of toothed belt, and includes a belt body 1 made of a polyurethane composition having teeth 2, 2,... With a predetermined pitch on the inner surface, and is provided at the bottom of each tooth 2 of the belt body. A cord 3 made of an aramid fiber as a tensile body is embedded along the line.
