た。 Conventionally, in cloth dryers, the degree of dryness of the cloth is determined by human sensation at the outlet of the dryer, or a moisture meter such as a tactile type is attached to the outlet to measure the moisture content of the cloth. However, since there are individual differences in human sense, it requires skill, and with a moisture meter, the official moisture content at the end of drying differs depending on the material of the cloth, so it must be corrected each time the material is different. There was an inconvenience that the operation was complicated.
本発明はかかる不都合のない乾燥機を提供する

示のような時間的変化を生ずる。 When drying cloth accumulates in the dryer, the surface temperature of the cloth when the humidity inside the dryer is constant is the inside temperature (Ta>Tb
>Tc), a temporal change as shown in the first diagram occurs. Point K of each characteristic curve is the surface temperature of the cloth at the time of completion of drying, which has a moisture content approximately equal to the official moisture content. When the temperature inside the machine is constant, the surface temperature of the cloth changes over time as shown in the second diagram depending on the value of the humidity inside the machine (Ha>Hb>Hc).

Similarly, when the temperature and humidity inside the machine are constant, the surface temperature of the cloth changes over time as shown in Figure 4, depending on the difference in cloth material (official moisture content w) (wg>wh>wi). .

To explain this flowchart, in step, the above-mentioned calculation formula and other necessary items are initially set, in step, the set machine internal temperature TMD , etc. are inputted using keys, and in step, calculations that can be performed by inputting the set input key are performed. , enter the machine status such as the temperature inside the machine and whether the fabric is placed on the machine in a ready state,
At the step, it is determined whether or not production can be started based on the input of the step, and if it is possible, this is notified by a buzzer or the like, and a production start signal is keyed in at the step. Attach the detection piece to the seam of the cloth,
This detection signal may be used as a start signal. Next, in step, the lowest speed signal within the control range of the motor is output, and in step, the cloth movement signal is input.
In the step, it is determined whether the cloth has reached the cloth surface temperature sensor 3. If the cloth has reached the cloth surface temperature sensor 3, in the step, the inside temperature T MD detected by the inside temperature sensor 1, the inside humidity H, and the inside temperature H detected by the cloth surface temperature sensor 3 are determined. Cloth surface temperature T MF and tacho generator 6c
The motor speed detected by is input, and in step the cloth surface temperature data T Mk is calculated based on the above formula, and in step the calculation result T Mk is compared with the temperature T MF detected by the cloth surface temperature sensor 3. . T MF at the step according to the comparison result at the step.
> T Mk , a speed increase signal is output, and T MF < T Mk , a deceleration signal is output, but for this purpose, in the step, when the deviation between T MF and T Mk is a large deviation greater than a predetermined value, outputs an increase (or decrease) speed signal proportional to the deviation, and if the difference between the previously measured T MF and the currently measured T MF is within △T, the increase (or decrease) is performed. Not output to speed signal, △T
If it is above, the calculation is performed so as to output an increase (or decrease) speed signal proportional to the deviation. In step, a cloth movement signal is input, and in step it is determined whether the cloth is at cloth surface temperature sensor 3 (if there is no cloth at sensor 3, it means that production is nearing the end). , if it is determined that there is no cloth 4, the cloth 4 is detected by the cloth surface temperature sensor 3.
Activates a timer set to the time from when the motor passes through to the end of the machine (determined by the current speed), and after that time has elapsed, a deceleration signal is output to stop the motor at the step, and the motor At the step when the motor stops, an off signal for the motor drive circuit is output. A human decides whether or not to produce again at the step, and if it is not produced again, it ends, and if it is produced again, it returns to the step.
