Abstract
A method for implementing a correct winding of a wire on a spool. The method is characterized in that it comprises a step for calculating the angular speed of a motor displacing a wire dispensing device according to the wire winding pitch and according to the pulling error, detected in relation to a given pre-set set-point and to a tolerance value, in order to determine the presence of a possible “valley error”, or of a possible “peak error”. Furthermore, if during the spool winding a “valley error” or a “peak error” is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device with the aim of filling the valley or of skipping the peak.
Claims7
A method for implementing a correct winding of a wire on a spool of a wire winding machine, the method comprising the following steps:
- (f1) setting main geometrical data of the spool on an operation panel of an electronic control unit;
- (f2) loading a spool on said wire winding machine;
- (f3) acquiring positions of the spool flanges by means of at least one sensor;
- (f4) calculating the actual spool position and comparing it with spool data stored in advance in the electronic control unit in order to check whether the spool loading was successful and whether the spool is consistent with expected parameters;
- (f5) continuing with the process if the check indicates successful spool loading;
- or stopping the process and reporting the problem by means of an alarm signal, if the check indicates unsuccessful spool loading;
- (f6) binding the wire to the spool;
- an operator starts the production by activating a specific command;
- (f7) reading a starting measure of the wire pulling action according to shape and construction geometry of a support/load cell assembly;
- (f8) calculating a servodiameter of the spool according to said spool data, production data, and the reading of said starting measure;
- and
- (f9) calculating the speed of a spool motor according to said servodiameter with the aim of maintaining a constant winding pulling action;
- and
- said method characterized in that it includes a further step for calculating the angular speed of a motor displacing a wire dispensing device according to a wire winding pitch and according to a pulling error, which is detected in relation to a given pre-set set-point and to a tolerance value, in order to determine the presence of a possible valley error, or of a possible peak error;
- and in that if during the spool winding a valley error or a peak error is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device with the aim of filling the valley or skipping the peak.
