An abnormality detecting apparatus for bags with handle. This apparatus comprises a pair of sensors (4) for measuring thickness of a handle portion (13) of each of the bags (2) with handle are provided on the way of a bag transfer unit (3) for transferring the bags (2) with handle in one direction. A detecting controller (6) is in communication with the sensors (4). An abnormality-warning output unit (19) is in communication with the detecting controller (6). Each of the sensors (4) comprises an idle roller (5) provided across the bag transfer unit (3), a detecting roller (11) disposed opposite to the idle roller (5) with the bag transferring unit (3) disposed therebetween, the detecting roller (11) biased toward the idle roller (5), and an access detector (15) for measuring a quantity of movement of the detecting roller (11). The access detector (15) converts a measured value into an electric signal to output the electric signal to the detecting controller (6). The detecting controller (6) compares the received measured value and a set value with each other. In a case where the measured value is out of a permissible range, a signal is sent to an abnormality-warning output unit (19). The abnormality-warning output unit (19) outputs an abnormality warning signal to the outside when the signal is received. <IMAGE> |
