apparatus and method for measuring the extension of the chain orbiting endlessly in the device

摘要

Apparatus equipped with a chain (1) which are arranged in circumferential to the endless (2) in the device (2) is provided with measuring apparatus for measuring elongation or stretching of (1) and (3) the chain weaving, the measuring device (3), (5) an second signal pickup unit (4) first signal pickup portion that is spaced intervals (D) relative to each other, the distance (D) is and extends in the running direction over several chain links of the chain (1) to (6). Signal should be generated as soon as passing the first signal pickup section (4) in the chain (1) to be orbiting, the first chain link signal generation for the first element (7), (6.1) above and disposed. (8), further signals are generated as soon as it passes the second signal pickup section (5) in the chain (1) each of the element (8) further the circulates signal generation for further elements of multiple so that, they are arranged second chain link (6.2) on. During one orbit of the chain (1), the number of signals to the second signal pickup section in (5) (NS2) is counted, the signal is the first signal of the first signal pickup unit (4) is generated before it is generated.
