FIG. 1 is a system diagram of an automatic winding device with a fuzzy control function unit according to the present invention. In FIG. 1, the configuration of the conventional automatic winding device is shown in the dashed line, and the wire tension device, the motor system, the mechanical system, the electrical system, the sensor system, The sequencer is controlled by an internal microprocessor. In the present invention, the sequencer is an automatic winding machine in which a fuzzy control function unit indicated by a two-dot chain line is added to the microprocessor for controlling each system. The fuzzy control function unit is based on fuzzy inference by membership function by creating rules for each control item compiled by experts and experts, modifying rules, checking rules, and recording conventional measurement values. The fuzzy control is performed. The calculation results based on the membership functions of the respective control items are respectively input to the fuzzy control function unit, and the program by the fuzzy control is input to the microprocessor. The fuzzy control is applied over the entire sequence control, PID control, optimal control, data processing, network, and man-machine functions. FIG. 2 shows a flowchart of the winding program of the automatic winding device.
When performing winding on a coil bobbin such as a transformer or a coil, in an automatic winding machine, particularly, an operator needs programming man-hours in connection with a lashing command, the number of lashes, a lashing direction, and a lashing in a winding command. These are control values for each control item such as speed, number of windings, winding direction, winding speed, tension on / off, etc. For this reason, conventionally, each time the specifications of each transformer and coil are different, they are created by completely independent programs. For this reason, it is generally difficult to share programs, so that when trouble occurs in equipment, it takes time to deal with the trouble, and much trouble is required to maintain the operation of the automatic winding machine. Therefore, each detailed part command instruction such as the karage and winding instruction, etc., for example, in the case of winding on a bobbin, taking into account the bobbin shape, each detailed part command instruction indicating the winding item is performed by fuzzy inference. The control value condition that was determined for each winding item using the membership function is controlled based on a composite calculation. Automatic winding under optimum conditions. Therefore, it leads to shortening and elimination of the man-hour for programming, and improvement of the quality of the transformer and the choke coil.

As an embodiment of the present invention, an automatic winding apparatus to which fuzzy logic is applied will be described with reference to FIG. FIG. 3A is a diagram in which a wire 1 is wound around a pin terminal 2 of a coil bobbin 4 attached to a bobbin winding jig 5 via a nozzle 3, and FIG. FIG. 7 is a diagram in which a wire is wound around a coil bobbin after the wire is wound.
If the wire 1 is slightly thinner and the pin terminal 2 is thicker, the speed is increased. FIG. 4 shows the theory of the tying of the wire to the pin terminal. FIG. 4A shows the wire diameter (m) of the wire on the horizontal axis.
m), the vertical axis indicates the grade value indicating the value of the fuzzy control, and indicates 1.0 when the control condition is the maximum. Therefore, the optimal control curve A for the wire diameter is a control curve that is a constant polygonal line at grade 1.0. FIG. 4B shows the relationship between the pin diameter and the grade of the pin terminal, and the control curve showing the relationship between the pin diameter and the grade is a polygonal line B at the maximum control condition grade 1.0. As shown in Fig. 1, when determining the grade for the wire diameter and the pin diameter of the pin terminal, as shown in Fig. 1, data accumulated by experts and specialists, rules created by analysis, rule correction, rules confirmation, etc. The control restriction input is determined by calculation using the ship function, and a fuzzy control program is input. Curve D in FIG. 4 (c)
Indicates the relationship between the rotation speed of the pin terminal when the wire diameter is specified and the grade of the estimated speed in the relationship between the wire diameter of the wire and the grade indicating the estimated speed, and the curve C indicates the pin when the pin diameter is specified. The relationship between the rotational speed of the terminal and the grade indicating the estimated speed is shown, and the intersection E of the curves C and D indicates the optimal rotational speed of the pin terminal. The speed of the point E can also be obtained from the center-of-gravity point calculation. Accordingly, in the diagram shown in FIG. 4, the y-axis is a membership function, which numerically shows the degree of the x-axis component based on the estimated speed based on the pin diameter, the wire diameter, and the like. Depending on the degree, each function is programmed, that is, regularized. The function of the number of revolutions corresponding to the rule is programmed, and the center of gravity E of each function of the number of revolutions, that is, FIG.
By calculating the membership function for the wire diameter and the pin terminal diameter, an appropriate pin terminal rotation speed (rotation speed) that does not cause disconnection can be selected. That is, by adding a fuzzy control function to the automatic winding device controlled by the conventional microprocessor, the speed for the wire diameter data and the speed data for the pin diameter are input, so that the wire diameter and pin Just by inputting the value of the diameter, the wire can be wrapped around the pin terminal at an appropriate speed. The winding of the wire can be performed at an appropriate speed only by inputting the circumference of the bobbin diameter, the wire diameter of the wire, and the like in the same procedure.

[0009]

The fuzzy control based on fuzzy inference in which a new control rule is input to a microprocessor for controlling a wire tensioning device, a motor system, a mechanical system, an electrical system, and a sequencer in a conventional automatic winding device is performed by the micro-processor. By adding to the processor, it is possible to provide an automatic winding device that automatically performs optimal control only by inputting constants of control items even when the specifications of the coil bobbin are changed.
