ABSTRACT:
A monitoring system for a wire handling machine, comprising a measuring unit for measuring an amount of wire consumption by the wire handling machine, and a control unit including memory for storing an expected amount of wire consumption for each of steps carried out by the wire handling machine, and a CPU having the functions of comparing an actual amount of wire consumption as detected by the measuring unit with a corresponding value stored in the memory, and producing an output indicative of a fault in the wire handling machine when any deviation exceeding a certain limit is detected between the actual amount of wire consumption and the corresponding value stored in the memory. Thus, the operating condition of the wire handling machine such as a motor armature coil winding machine can be accurately evaluated by the amount of wire consumption which can be easily measured with a simple device for measurement, for instance by using a rotary encoder coupled with a pulley around which the wire is passed. Furthermore, since a failure in the wire winding machine can be detected as soon as it occurs, a costly system down and waste of coil wire can be minimized by equipping the control unit with an arrangement for stopping the operation of the wire handling machine upon detection of the output indicative of a failure in the wire handling machine.
