Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention prevents hair from being thermally damaged by controlling a hair iron with a computer when performing hairdressing and beauty treatment of the hair using the hair iron. The present invention relates to a computer-assisted ironing and barber beauty method capable of easily creating a hair design including various curls or waves.

[Prior Art] Generally, when forming a hair design including various curls and waves with a hair iron, the practitioner operates the hair iron while considering the temperature and the number of rotations of the rod.

Recently, various techniques have been proposed for automatically maintaining the temperature of the rod at a temperature at which hair is not thermally damaged and for automatically rotating the rod with a motor.

[Problems to be Solved by the Invention] Conventionally, automatic control of the temperature of the rod and automatic rotation of the rod by a motor have been developed separately. For this reason, no technology has emerged that controls the rod temperature and the motor rotation speed in a rational relationship, and for this reason, the condition in which heat damage to the hair often occurs is a problem for the user. Can occur even with sufficient caution. The reason is that, in order to make the heat energy that the hair receives from the rod proper, for example, adjusting the number of revolutions of the motor to the optimum number of revolutions per second with respect to the current rod temperature does not affect human attention or attention. This is because the limit of judgment is exceeded.

The present invention aims to reduce mental and physical fatigue of a practitioner of a barber beauty technique using this type of hair iron, and at the same time, provides a computer-aided iron barber beauty treatment method that can give the subject a sense of security and reliability. Is intended to provide.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a rod having a built-in heater for heating hair and a hair provided between the rod and the rod so as to open and close so as to face the rod. In the barber-cosmetic method of ironing the hair using a hair iron in the form of ironing the hair by rotating the rod with a motor equipped with a glove for sandwiching the rod temperature and motor rotation for each hair style A computer in which a plurality of hair style action programs are optimally set in a range that does not cause heat damage to hair, a program changer for selecting a plurality of hair style action programs in the computer, and an iron Of the combination data of the rod temperature and the motor rotation speed in which the degree of ironing (ironing effect) is stored in the computer. Using an ironing effect changer that searches from inside and changes the setting, the temperature controller and rotation control of the rod temperature and the motor rotation speed of the hair iron by a computer under the conditions set by the program changer and the ironing effect changer. The hair is automatically controlled through a device to shape the hair into a desired hairstyle.

[Operation] A hairstyle creation program corresponding to the hairstyle desired by the subject is set by the program switching device, and the iron effect switching device is set so as to meet the wishes of the subject, and the hair iron is operated. The hair temperature of the surgeon is accurately controlled by a computer in real time every second to control the rod temperature and the number of rotations of the motor for each bundle, and the hair is formed into a desired hair shape without causing thermal damage to the hair. If the hair is not in the desired shape, change the setting of the iron effect selector to make it appropriate.

[Example] The hair iron used in the example of this method is the patent application No. 5918 (Japanese Patent Publication No. 4-58324) filed by the present applicant in 1986.
No.), the structural function of the automatic hair iron is described in detail in Japanese Patent Publication No. 4-58324 relating to the above-mentioned patent application, so only a brief description will be given here.

FIG. 1 shows the device used in this method, the upper half of which is the above-mentioned automatic hair iron, and the lower half of which is a controller incorporating a computer. In the drawings, (1) is an iron body, (2) is a rod, (3) is a glove,
(4) is a roller that opens and closes together with the glove and is forcibly rotated in the opposite direction to the rod at a peripheral speed almost equal to the peripheral speed of the rod, and (5) is a handle for opening and closing the glove. Can be opened from the A position to the A'position to pinch the hair between the rod and the glove returns to the A position by the force of the spring (8) and presses the hair against the rod when the handle is released. (7) is a power source for rotating and driving the rod by a DC motor with a speed reducer.

The hair iron is connected to the controller through an electric wire and an iron plug (14) extending to the right in the figure,
When the operation switch (6) is turned on, the motor rotates according to the program of the computer to perform the ironing work. When the operation switch is turned off, the motor stops and the ironing work is stopped, but only the heater keeps a predetermined temperature. Controlled as. (10) is the controller body, and the iron effect switching device (12) and the program switching device (1
3) There is a knob for operating, and turn it to give an instruction by aligning the index with an arbitrary scale. (11) is a power switch for driving the controller and iron, and (15) is a power plug for inserting into an outlet.

The ironing effect is represented by the ratio of the radius r of the rod to the radius of curvature R of the treated hair.

The relation of the above equation can also be expressed as follows.

Therefore, the greater the ironing effect, the smaller the radius of curvature R of the treated hair, and if the ironing effect becomes infinitely smaller, the radius of curvature of the treated hair becomes infinite (straight line).

Next, the factors that influence the ironing effect will be described.

3 and 4, (2) is a rod, (9) is a heater, (3) is a glove, (4) is a roller, the rod rotates counterclockwise at a peripheral speed V, and the roller rotates clockwise. When forced to rotate at the same circumferential speed to, the untreated hair (17) is heated from the rod at temperature T while being fed at speed V from position P to position Q.

At this time, as the temperature of the rod is higher and the rotation of the rod (the rotation of the motor) is slower, the thermal energy that the hair receives from the rod receives a larger amount of thermal energy.

When the hair receives heat energy, the chemical structure of keratin, which is the main component of the hair, changes and the elasticity temporarily decreases.As a result, the plastic is deformed so that it approaches the curve of the rod surface, and then it is discharged from the iron and exposed to the outside air. The original amount of plastic deformation increases as the amount of thermal energy received by the hair increases, and the radius of curvature R of the discharged hair decreases. Become.
In other words, the greater the amount of heat energy the hair receives, the greater the ironing effect.

In summary of what has been described above, the higher the temperature of the rod and the slower the rotation of the motor, the greater the ironing effect and the smaller the radius of curvature of the treated hair.

Therefore, the hair in FIG. 3 is an example in which the temperature of the rod is relatively high or the rotation of the motor is slow, and the hair in FIG. 4 is an example in the opposite case. Curvature radius R of treated hair
Can be said to be smaller in FIG. 3 and the ironing effect to be greater in FIG. As a result of actually changing the ironing effect and examining the radius of curvature of the hair after the treatment, the ironing effect is 0.9 by properly selecting the temperature of the rod and the rotation speed of the motor.
It turns out that it can be arbitrarily changed from to infinity. The data that caused heat damage to the hair was deleted from the large number of combination data of rod temperature and motor rotation speed, and the data was put into practical order.

Even if a combination of rod temperature and motor speed is randomly extracted from the data set obtained in this way and is put into practice, the result gives the hair an ironing effect corresponding to that data. Since no data that causes heat damage to the hair is included, it is possible to eliminate the heat damage to the hair by the iron by using the above data in the control system.

The above-mentioned practical data group is stored in the read-only memory of the computer and is referred to each time the control is performed.

FIG. 2 is a block diagram for easy understanding of the control function. Corresponding to FIG. 1, the heater (9), the motor (7), and the operation switch (6) belong to the iron, and the iron effect switching is performed. Device (12), program selector (1
3) is on the surface of the controller body (10), and is a computer such as a microprocessor (19), a read-only memory (20), a read / write memory (21), an input / output device (22), a power supply device (23), etc. The part (24), the rotation controller (25), the temperature controller (26), and the temperature detecting part (27) are built in the controller body (10).

(A) A microprocessor (19) is a central processing unit that controls the entire computer, and is a read-only memory (RO
M) (20), read / write memory (RAM) (21), and input / output device (I / O) (22) are connected to each other by signal lines and execute programs, manage memory, input / output data, etc. Do.

(B) The read-only memory (20) stores the above-mentioned data group and a plurality of user programs for determining the hairstyle.

(C) The read / write memory (21) is used for temporary storage of data and the like during program execution.

(D) The input / output device (22) is for inputting / outputting signals between the microprocessor (19) and external equipment.
A temperature command is issued to the temperature controller (26), and a rotation control signal is output to the rotation controller (25).

Iron effect switching device (12) and program switching device (13)
A signal for identifying which graduation the user has designated by turning the knob is input from, and a signal for determining whether it is ON or OFF is input from the operation switch (6).

(E) When the user selects a desired ironing effect and adjusts the knob to the scale, the ironing effect selector (12) outputs a signal specific to the scale through the input / output device (22) to the microprocessor (19). Send to the microprocessor (19)
While interpreting the signal as a specific ironing effect, a pair of data of the rod temperature and the motor speed corresponding to this is searched for from the data group stored in the read-only memory (20) and found. The data of the rod temperature is output to the temperature controller (26) via the input / output device.

(F) The temperature controller (26) functions to control the temperature of the heater (9). The heater (9) heats the rod (2) by generating resistance heat by an electric current, but the resistance value changes depending on the temperature, so that the temperature detecting section (27) constantly monitors the resistance value of the heater (9). When the resistance value monitored by interpreting the rod temperature data received in (e) as a resistance value command of the heater (9) corresponding to the temperature is smaller than the commanded resistance value, a large current is supplied to the heater (9). )
To rapidly heat the rod (2), and when the monitored resistance value is equal to or higher than the commanded resistance value, a small current is passed to the heater (9) to prevent the temperature of the rod (2) from further increasing. To do so.

(G) The rotation controller (25) functions to control the rotation speed of the motor (7). The rotation speed of the motor (7) is controlled by a pulse width control method. That is, for each constant cycle time (cycle constant), a pulse current is applied to the motor for an ON time (ON constant) shorter than the cycle period, By increasing / decreasing the duty ratio represented by, the average current supplied to the motor (7) is increased / decreased to control the rotation speed.

The rotation speed data of the motor (7) retrieved in the previous section (e) is interpreted as an ON constant by the arithmetic unit of the microprocessor (19), and rotation control is performed via the input / output device (22) at the same time as the start of the cycle. The motor is controlled to the number of revolutions according to the data by sending an ON signal to the device (25) and sending an OFF signal at the end of the ON time.

In the iron of the embodiment, since the load of the motor (7) hardly changes, it is necessary to measure the actual rotation speed of the motor (7) and feed back the result to the microprocessor (19) to control the rotation speed to be accurate. Sufficient control is possible without using the regular control method.

(H) When the user selects a desired user program on the program switch (13) and adjusts the knob to the scale,
A signal specific to the scale is input to the microprocessor (19) via the input / output device. The microprocessor (19) selects and executes a program corresponding to the above signal from a plurality of user programs for hairstyle creation stored in the read-only memory (20).

(I) When the operation switch (6) is turned off, the computer executes only the system program, and when turned on, it executes both the system program and the user program described in (h) above.

The system program is a program for controlling the iron effect switching device (12), the temperature controller (26), the heater (9), and the temperature detection unit (27). In the event of a hardware failure that causes the temperature in (9) to become higher than the indicated temperature, interrupt the microprocessor (19) and cause the temperature controller (26) to shut off the heater circuit. , Is a program for managing the overall system. The system program cannot be modified by the user.

When the operation switch (6) is turned on, the user program for the hairstyle creation action selected by the user is executed together with the above system program, and the motor is rotated to iron-form the hairstyle as specified by the program.

The user program can be changed freely as desired by the user.

Next, an embodiment of the computer-aided ironing work of the present invention will be described with reference to FIGS.

In FIGS. 5 and 6, (16) shows a cross section of the hair iron, (17) shows untreated hair, and (18) shows treated hair.

When the power plug (15) of FIG. 1 is plugged into a power outlet and the power switch (11) of the controller body (10) is turned on, the computer starts up.

When the knob of the ironing effect selector (12) is adjusted to the desired ironing effect scale, the heater (9) is heated to a predetermined temperature by the action described in (e) above.

When the knob of the program changer (13) is adjusted to the scale of the desired hairstyle, the user program for creating the designated hairstyle by the action described in (h) above is selected and ready for execution.

When the handle (5) of the hair iron is pushed to open the glove (3), the sliced hair is pinched, the handle (5) is released, and the glove (3) is closed to obtain the state shown in FIG.

Immediately after this, when the operation switch (6) in FIG. 1 is turned on, the motor (7) rotates as described in (i) above, and the sixth
As shown in the figure, the untreated hair (17) is fed and the treated hair (18) is discharged, but at this time, the treated hair is not loosened and the iron (10) is kept taut as shown in FIG. 16) should be kept away from your head.

FIG. 7 shows a case where a user program is executed to keep the ironing effect constant all the time, and the hair (18) after passing through the iron is curled with a constant radius of curvature as shown in the figure.

FIG. 8 shows a case where a user program is executed in which the ironing effect is increased or decreased at a constant distance along with the progress of hair, and the hair after treatment after passing through the iron ( In 18), the part where the ironing effect was large was strongly curled and remained convex, and the part where the ironing effect was small was curled weakly, so the hair was stretched by its own weight, and as a result, as shown in the figure. It has the same shape as a wave made by intermittently ironing.

In the above two embodiments, the iron effect switching device (12)
And the ironing effect is made smaller than that of the embodiment.
When the user program shown in the figure is executed, the radius of curvature of the curl becomes larger than that in the figure, and the curl feels soft.

When the ironing effect selector (12) is switched to make the ironing effect larger than that of the embodiment and the user program shown in FIG. 8 is executed, the convex portions are emphasized more than in the drawing, so that the wave feels harder. .

As described above, in the hair iron having a structure in which the rod (2) heated by the heater (9) is rotated by the motor (7) to iron the hair, the iron is of the type shown in the embodiment. Not only the iron but also a mechanical difference such as a type in which the rod (2) and the glove (3) both rotate in the same direction, or a type in which the rod (2) and the glove (3) rotate in opposite directions. Regardless of the temperature of the rod (2) and rotation of the motor (7)
It is extremely difficult to control the large elements in relation to each other, reasonably, precisely and in real time without computer assistance. With the conventional control method in which the two factors of the rod temperature and the motor rotation are separately controlled without being rationally related, a condition in which heat damage to the hair often occurs may occur even if the user is careful. Of. The reason is to adjust the rotation of the motor (7) to an optimum number of revolutions per second for the current rod temperature in order to optimize the heat energy the hair receives from the rod (2): This is because it exceeds the limits of human attention and judgment.

For the same reason, irregularities in the ironed curls or waves also result from the disparity in the thermal energy received by the hair.

As is apparent from the above reasons and the results described in the examples, a computer was used to control the hair iron in which the motor (7) rotates the rod (2) heated by the heater (9). Ideally, a control device should be used in combination, which increases the reliability of the iron barber and iron beauty methods, and brings good news to many people including the practitioner and the subject.

[Effect of the Invention] According to the present invention, the rod temperature and the motor rotation number of the subject's hair are accurately controlled in association with the computer in real time every second to prevent heat damage to the hair. It can be shaped into the desired hairstyle without giving it, and it does not force the practitioner to have excessive attention, concentration and skill, and also reduces the labor, and at the same time, it is safe and reliable for customers. There is an advantage that can be improved.
