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 structure of a conventional automatic winding device is shown in the alternate long and short dash line, and a wire tension device, a motor system, a mechanical system, an electrical system, a sensor system, which is a control target during winding of the winding device body, Although the sequencer was controlled by an internal microprocessor, the present invention is an automatic winding machine in which a fuzzy control function unit indicated by a chain double-dashed line is added to the microprocessor for controlling each system. The fuzzy control function unit is based on fuzzy reasoning based on membership functions by recording the measured values of the conventional control rules based on the rule creation, rule modification and rule confirmation for each control item compiled by experts and experts. The fuzzy control is performed, and the calculation result based on the membership function of each control item is input to the fuzzy control function unit, and the program by the fuzzy control is input to the microprocessor. Fuzzy control is applied to all sequence control, PID control, optimum control, data processing, network, and man-machine functions. FIG. 2 shows a winding program flowchart of the automatic winding device.
When winding a coil bobbin such as a transformer or a coil, it is necessary for an operator, especially in an automatic winding machine, to have programming man-hours. It is a control value for each control item such as speed, number of windings, winding direction, winding speed, tension on / off, etc. Mainly the pin terminal diameter at the time of tangling work, the winding to the bobbin is the bobbin shape. In the past, however, in the past, each transformer and coil had different specifications, and they were created by completely independent programs. Therefore, it is generally difficult to share a program. Therefore, when a trouble occurs in the facility, it takes time to deal with it, and it takes a lot of trouble to maintain the operation of the automatic winding machine. Therefore, fuzzy inference is performed for each detailed portion command instruction such as the above-mentioned winding and winding instruction, for example, for winding the bobbin, in consideration of the bobbin shape. It is configured to control the condition of the control value decided for each winding item using the membership function of the above, based on the composite calculation, and it is automatic only by inputting the setting conditions of multiple winding items. Automatic winding is performed under optimum conditions. Therefore, the number of programming steps can be shortened and omitted, and the quality of the transformer and choke coil can be improved.

As an embodiment of the present invention, an automatic winding device to which the fuzzy theory is applied will be described with reference to FIG. 3A is a diagram in which the wire rod 1 is wound around the pin terminal 2 of the coil bobbin 4 attached to the bobbin winding jig 5 through the nozzle 3, and FIG. It is the figure which has wound the wire around the coil bobbin after entanglement.
If the wire 1 is a little thin and the pin terminal 2 is thick, the twisting speed is increased. Figure 4 shows the theory of wire entanglement on pin terminals. In FIG. 4A, the horizontal axis indicates the wire diameter (m
m), the vertical axis indicates the grade value indicating the value of fuzzy control, and indicates 1.0 at the maximum control condition. Therefore, the optimum control curve A with respect to the wire diameter is a control curve with grade 1.0 and a constant polygonal line. FIG. 4B shows the relationship between the pin diameter of the pin terminal and the grade, 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. To determine the wire diameter and the grade for the pin diameter of the pin terminal, as shown in Fig. 1, accumulated values of data by experts, experts, rule making by analysis, rule correction, rule confirmation, etc. By the calculation using the ship function, the control regulation input is determined and the fuzzy control program is input. Curve D in FIG. 4 (c)
Shows the relationship between the rotational 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 is the pin when the pin diameter is specified. The relationship between the terminal rotation speed and the grade indicating the estimated speed is shown, and the intersection E of the curves C and D shows the optimum pin terminal rotation speed. The velocity of the point E can also be obtained by calculating the center of gravity. Therefore, in the diagram shown in FIG. 4, the y-axis is the membership function, which numerically shows the degree of the x-axis component due to the estimated speed depending on the thickness of the pin diameter, the thinness of the wire diameter, and the like. Depending on the degree, each function is programmed, that is, regularized. By programming the function of the rotation speed corresponding to the rule, the center of gravity E of each rotation speed function, that is, FIG.
Then, by obtaining the membership functions for the wire diameter and the pin terminal diameter, it is possible to select an appropriate rotation speed (rotation speed) of the pin terminal that does not cause disconnection. In other words, by adding a fuzzy control function to the automatic winding device that was controlled by the conventional microprocessor, by inputting the speed data for the wire diameter data and the speed data for the pin diameter, By simply inputting the diameter value, the wire rod can be twisted to the pin terminal at an appropriate speed. For the winding, the wire rod can be wound at an appropriate speed simply by inputting the circumference of the bobbin diameter, the wire diameter of the wire rod, and the like in the same procedure.

[0009]

The fuzzy control by the fuzzy inference in which the control rule is newly input to the microprocessor for controlling the tension device for the wire rod, the motor system, the mechanical system, the electrical system and the sequencer in the conventional automatic winding device is described above. By adding it to the processor, even if the specifications of the coil bobbin are changed, it is possible to provide an automatic winding device that automatically performs optimum control simply by inputting constants of control items.
