Abstract
The invention relates to a monitoring means (1) for an end of a thread-like material (2) wound on a storage coil (3), in particular an electrical conductor provided with an electrically insulating coating for a processing machine, comprising a computer unit (24) and a memory location (25, 26) for a desired residual quantity of the thread-like material (2). A weighing device (17 to 22) is provided for at least intermittently receiving the storage coil (3), the measured value transducer of which is connected to the computer unit (24) and a further memory location (25, 26) is provided for the tare weight at least of the storage coil (3).
Claims36
Monitoring means for an end of a thread-shaped material wound on a storage coil, the monitoring means forming part of a processing machine and comprising
- (a) a computer unit including
- (1) a first memory location for storing a predetermined desired value for a desired residual quantity of the thread-shaped material and
- (2) a further memory location for storing the tare weight of the storage coil;
- and
- (b) a weighing device including a measured value transducer, the weighing device at least intermittently receiving the storage coil for measuring the actual value of weight, and the meassured value transducer being coupled to the computer unit, the computer unit determining when the sum of the desired value of the desired residual quantity and the tare weight of the storage coil correspond to the actual value.
A process for monitoring an end of a thread-shaped material unwinding from a storage coil during processing of the unwound thread-shaped material, which comprises the steps of weighing the storage coil, continuously measuring values of the weight, feeding the measured values to a computer unit, and comparing the measured values with a predetermined value of a residual quantity of the thread-shaped material on the storage coil.
