    • The invention relates to a method for monitoring a continuous revolving conveyor belt (4) having a connecting region (8). The connecting region (8) is monitored with the aid of two transponders (12) and (14). One of the transponders is arranged forward of the connecting region (8) and the other transponder is connected rearward of the connecting region (8). Both transponders (12) and (14) transmit respective signals to an external transmitter/receiver unit 16 wherein a conclusion is drawn as to the spacing of the two transponders (12) and (14) on the basis of the time-dependent spacing of the two signals. If the spacing s of the transponders (12) and (14) exceeds a pregiven amount, then a conclusion is drawn by the external transmitter/receiver unit (16) as to a critical change in length of the connecting region (8) and corresponding measures are initiated.
    • 本发明涉及一种用于监测具有连接区域(8)的连续旋转传送带(4)的方法。 借助于两个转发器(12)和(14)来监视连接区域(8)。 一个应答器布置在连接区域(8)的前方,另一个应答器连接在连接区域(8)的后方。 两个应答器(12)和(14)将相应的信号发送到外部发射机/接收机单元16,其中根据时间依赖的间隔对两个应答器(12)和(14)的间隔作出结论 两个信号。 如果应答器(12)和(14)的间隔超过预定量,则外部发射器/接收器单元(16)得出关于连接区域(8)的长度的临界变化和相应的 开始采取措施。

    • The invention relates to a system for monitoring a layer (8), which is subjected to wear, of a composite structure (2) and relates especially to a system for monitoring the cover layer (8) of a conveyor belt (2). The monitoring system includes a transmitter/receiver device (4) which continuously generates an electromagnetic field. A ferromagnetic layer (16) of high permeability is embedded in the cover layer (8) and shields a transponder (6), which is embedded in the conveyor belt (2), from the electromagnetic field as long as it is not damaged by wear. The transmitter/receiver device (4) recognizes the wear of the cover layer (8) in that it receives data from the transponder (6) because, in this case, the ferromagnetic layer (16) is damaged over a large area. The invention also relates to a method for monitoring a composite structure (2) having a layer (8) subjected to wear. The invention relates especially to a method for monitoring the cover layer (8) of a conveyor belt (2).
    • 本发明涉及一种用于监测复合结构(2)磨损的层(8)的系统,特别涉及用于监测传送带(2)的覆盖层(8)的系统。 监控系统包括连续产生电磁场的发射机/接收机设备(4)。 高导磁率的铁磁层(16)嵌入在覆盖层(8)中,并且屏蔽了埋入输送带(2)中的应答器(6),只要它不被磨损而损坏电磁场 。 发射机/接收机设备(4)识别覆盖层(8)的磨损,因为它接收来自应答器(6)的数据,因为在这种情况下,铁磁层(16)在大面积上被损坏。 本发明还涉及一种用于监测具有经受磨损的层(8)的复合结构(2)的方法。 本发明尤其涉及用于监测传送带(2)的覆盖层(8)的方法。

    • A tubular belt conveyor system includes a conveyor belt having a cross-sectionally closed, curvilinear, tubular configuration including a zone of overlapping edge portions. A plurality of support and guide assemblies for the conveyor are situated along the conveyor path. Each assembly includes a plurality of support and guide rollers held about the cross-sectionally closed conveyor belt in a contacting relationship therewith. In each assembly one roller is in engagement with the cross-sectionally closed conveyor belt at the edge overlap. The closed tubular configuration in each length portion of the conveying path has an oval cross section. The support and guide rollers force the conveyor belt into the closed tubular configuration of oval cross section. The first support and guide roller of each assembly is settable onto the zone of overlapping edge portions.
