That is, the rubber belt 30 includes a reinforcing rubber layer formed of the reinforcing rubber 6 and a cover rubber layer formed of the cover rubber 4;

コンベヤベルト１の製造方法を説明する。
まず、磁性粉を混入したゴムを未加硫状態で着磁したゴム磁石７（以下、未加硫ゴム磁石７という）を形成しておく。
次に、例えば、図１に示すように、カバーゴム４を巻いた巻枠８から巻き出されたカバーゴム４と補強ゴム６を巻いた巻枠９から巻き出された補強ゴム６とカバーゴム５を巻いた巻枠１０から巻き出されたカバーゴム５とが重ねられた状態で圧着ローラ１１；１１に通された後に、これらカバーゴム４と補強ゴム６とカバーゴム５とが互いに圧着されて形成されたゴムベルトが加硫機１２に送られて加硫されるゴムベルト製造工程において、カバーゴム４と補強ゴム６とカバーゴム５とが圧着ローラ１１；１１により圧着される前に、カバーゴム４、補強ゴム６、カバーゴム５のいずれかの上に未加硫ゴム磁石７が設置された後に、カバーゴム４と補強ゴム６とカバーゴム５とが圧着ローラ１１；１１に通されることによって、図２に示すような、未加硫ゴム磁石７が埋め込まれた状態のゴムベルト２０が形成される。
そして、ゴムベルト２０が加硫機１２に送られ、加硫機１２による加硫加工によって、未加硫ゴム磁石７とゴムベルト２０の未加硫ゴムベルト４０（図２参照）とが一緒に加硫される。
以上により、図３に示すような、加硫によりゴム磁石３とゴムベルト３０とが良好に接着されたゴム磁石付きゴムベルト２が製造される。ゴム磁石付きゴムベルト２は巻枠１６で巻き取られる（図１参照）。
このように形成されたゴム磁石付きゴムベルト２が帯状となるように任意の長さに切断され、その帯状のゴム磁石付きゴムベルト２の一端と他端とが繋なぎ合わされて無端状のコンベヤベルト１が形成される（図４参照）。 A method for manufacturing the conveyor belt 1 will be described.
First, a rubber magnet 7 (hereinafter referred to as an unvulcanized rubber magnet 7) is formed by magnetizing rubber mixed with magnetic powder in an unvulcanized state.
Next, as shown in FIG. 1, for example, the cover rubber 4 unwound from the winding frame 8 wound with the cover rubber 4 and the reinforcing rubber 6 unrolled from the winding frame 9 wound with the reinforcing rubber 6 and the cover rubber. After the cover rubber 5 unwound from the winding frame 10 wound with 5 is passed through the pressure roller 11; 11, the cover rubber 4, the reinforcing rubber 6 and the cover rubber 5 are pressure-bonded to each other. In the rubber belt manufacturing process in which the formed rubber belt is sent to the vulcanizer 12 and vulcanized, before the cover rubber 4, the reinforcing rubber 6 and the cover rubber 5 are pressure-bonded by the pressure rollers 11; 4. After the unvulcanized rubber magnet 7 is installed on any one of the reinforcing rubber 6 and the cover rubber 5, the cover rubber 4, the reinforcing rubber 6 and the cover rubber 5 are passed through the pressure roller 11; 11. Shows in Figure 2 Do, rubber belt 20 in the state unvulcanized rubber magnet 7 is embedded is formed.
Then, the rubber belt 20 is sent to the vulcanizer 12, and the unvulcanized rubber magnet 7 and the unvulcanized rubber belt 40 (see FIG. 2) of the rubber belt 20 are vulcanized together by vulcanization processing by the vulcanizer 12. The
As described above, as shown in FIG. 3, the rubber belt 2 with rubber magnet in which the rubber magnet 3 and the rubber belt 30 are well bonded by vulcanization is manufactured. The rubber belt 2 with a rubber magnet is wound up by a winding frame 16 (see FIG. 1).
The rubber belt 2 with rubber magnets formed in this way is cut to an arbitrary length so as to form a belt shape, and one end and the other end of the rubber belt 2 with the rubber belt magnet are joined to each other, and the endless conveyor belt 1 is connected. Is formed (see FIG. 4).

最良の形態によれば、磁性粉を混入したゴムを未加硫状態で着磁して未加硫ゴム磁石７を形成した後に、未加硫ゴムベルト４０と未加硫ゴム磁石７とを一緒に１回だけ加硫したので、ゴム磁石３とゴムベルト３０との界面での接着状態が良好となり、また、ゴム磁石３のゴムも過加硫状態とならない。従って、ゴム磁石３とゴムベルト３０との界面での剥離の問題やゴム磁石３のゴム物性の低下の問題の少ないコンベヤベルト１を得ることができる。   According to the best mode, after the rubber mixed with magnetic powder is magnetized in an unvulcanized state to form the unvulcanized rubber magnet 7, the unvulcanized rubber belt 40 and the unvulcanized rubber magnet 7 are joined together. Since the vulcanization is performed only once, the adhesion state at the interface between the rubber magnet 3 and the rubber belt 30 is good, and the rubber of the rubber magnet 3 is not overvulcanized. Therefore, it is possible to obtain the conveyor belt 1 with less problems of peeling at the interface between the rubber magnet 3 and the rubber belt 30 and problems of deterioration of the rubber physical properties of the rubber magnet 3.

尚、未加硫ゴム磁石７の設置作業は、専用のロボット、あるいは、作業員による手作業によって行う。
また、ゴム磁石３の配置形態は特に制限されない。例えば、ゴム磁石３がゴムベルト３０の長手方向に所定間隔で配置されたコンベヤベルト１や、ゴム磁石３がゴムベルト３０の幅方向に所定間隔で配置されたコンベヤベルト１とすればよい。 The unvulcanized rubber magnet 7 is installed by a dedicated robot or manually by an operator.
Further, the arrangement form of the rubber magnet 3 is not particularly limited. For example, the conveyor belt 1 in which the rubber magnets 3 are arranged at predetermined intervals in the longitudinal direction of the rubber belt 30 or the conveyor belt 1 in which the rubber magnets 3 are arranged at predetermined intervals in the width direction of the rubber belt 30 may be used.

本発明のコンベヤベルト１は、コンベヤベルト１の磨耗検出、コンベヤベルト１の蛇行検出などのコンベヤベルト１の性状を検出するためのベルトモニタリングシステムに使用される。   The conveyor belt 1 of the present invention is used in a belt monitoring system for detecting the properties of the conveyor belt 1 such as detecting the wear of the conveyor belt 1 and detecting the meandering of the conveyor belt 1.
