Description

  The present invention relates to a garment finishing method and apparatus for press finishing textile garments such as washed shirts, suits, and trousers.

  Patent Documents 1 and 2 can be cited as examples of clothing finishing methods and apparatuses therefor.

  In Patent Document 1, a pair of hot plates are disposed opposite to the front and back surfaces of a trunk on which a shirt is placed. The trunk is composed of a suction passage formed in a container shape by a core plate that is a perforated plate, and an exterior body that covers the outside of the core plate. The exterior body is provided with a breathable pad material that covers the periphery of the core plate, and is formed so that air can freely communicate with each other through a cavity between the pad material and the core plate. An air suction device is connected to the suction passage of the trunk.

  Therefore, when a shirt is set on the trunk and the air suction device is operated, the suction passage is sucked, the cavity of the exterior body becomes negative pressure, and the surface of the trunk is sucked by air. Thereby, the shirt is held on the trunk. When the start button is pressed, the pair of hot plates move forward to press finish the shirt.

  In Patent Document 2, a hot plate is installed above an iron support that is provided so as to be movable up and down. On the iron support base, there is provided an iron base comprising an iron base for finishing the shirt collar and an iron base for finishing the sleeve. A hollow portion is formed inside the iron support base, and this hollow portion is connected to an air suction device. . In the ironing table for finishing the buttock and the sleeve, the surface of the crimping plate is covered with a breathable pad material. The top plate of the crimping plate has a large number of air holes formed on the surface.

  Therefore, when the shirt is set on the ironing board and the air suction device is operated, the inside of the ironing support board is sucked in air, and the shirt is sucked in air through the vent hole of the pressing board of the ironing board and the air-permeable pad material. Thereby, the shirt is held on the ironing board. Pressing the start button raises the ironing board and presses the shirt with a hot plate.

  Although not disclosed in Patent Documents 1 and 2, in such a garment finishing apparatus, when a shirt is pressed with a torso and a hot plate (Patent Document 1) or a shirt is pressed with an ironing board and a hot plate (Patent Document 2). At the same time, the air suction unit is activated.

  In the above-described garment finishing apparatus, improvement in production efficiency has been desired. As a result of repeated experiments and studies, the present applicant has found that production efficiency can be improved by improving the relationship between clothing press and air suction.

  An object of the present invention is to provide a garment finishing method and apparatus capable of improving production efficiency.

Claim 1 of the present invention for solving the above-mentioned problems is a clothing finishing method in which clothing is air sucked with an air sucker and held on an ironing board, and the clothing is pressed with a heated hot plate. Press with a plate, detect the temperature at which the temperature of the clothing changes from a sudden rise to a substantially constant temperature within the temperature range of 97 ° C to 99 ° C, turn on the air suction device to suck in air , and wear the clothing at a temperature of 100 ° C or higher The air sucker detects a temperature at which the temperature suddenly rises from a substantially constant temperature due to drying , releases the press by the hot plate, and after a predetermined time after detecting the temperature at which the temperature suddenly rises from the constant temperature It is characterized by turning off.

According to a second aspect of the present invention for solving the above-mentioned problems, in the garment finishing apparatus , the garment finishing apparatus includes an air suction device that sucks the garment in air and holds the garment on the ironing board, and a hot plate that presses the garment.

[Background to the Present Invention]
First, the background to the present invention will be described. Experiments and investigations were performed using a double color cuff press machine (YPS-502A) manufactured by YAC Corporation that implemented the structure of Patent Document 2.

  As an experiment, tests 1, 2, and 3 were performed as shown in [Table 1]. In this case, the test was performed under the conditions of a pressing force (air pressure) to the shirt of 0.7 MPa and a vapor pressure of 0.5 MPa (temperature of the hot plate 154 ° C.) for blowing steam into the hot plate. Here, the saturated water vapor pressure is a pressure of 0.54333 MPa at a temperature of 155 ° C. according to the “Steam Table” of the Japan Society of Mechanical Engineers. In Table 1, the fabric Po represents polyester fiber, and Co represents cotton fiber. Tests 1, 2 and 3 were washed under a single washing machine and dehydrated in the same time to keep the same conditions. Test 1 shows a case where the air suction device is always turned on, and Test 2 shows a case where the air suction device is always turned off. Therefore, tests 1 and 2 were performed on seven shirts. In order to eliminate measurement errors, the average values of tests 1, 2, and 3 indicate the average value of five shirts by omitting one of the maximum and minimum values of the seven shirts. For example, test 1 omits shirt 3 49 and shirt 7 21. As apparent from the results of Tests 1 and 2, the average value of the drying time TM was 37.4 seconds for Test 1 and 22.2 seconds for Test 2.

  Considering the cause, it was speculated that when the air suction device was always turned on as in Test 1, the hot plate was cooled by the air suction device, and the drying time TM was prolonged. Therefore, the present inventor conducted an experiment of Test 3 shown in [Table 1] in which the air aspirator is turned on after a certain time based on the hypothesis.

  In test 3, the air aspirator was turned on 5 seconds after the start of the apparatus. As a result, the average value of the drying time TM was 21.2 seconds, and it was possible to shorten the drying time TM from Test 2 as well as from Test 1. Therefore, if the time for turning on the air suction device is changed in various ways to find a preferable time and the air suction device is set to be turned on at that time, the drying time TM can be shortened. However, since the drying time TM varies depending on the wetness of the shirt, the material, the device usage environment, etc., it is difficult to set the best time.

The present invention examined the relationship between temperature rise and time when performing tests 1, 2, and 3. As a result, a temperature rise characteristic was obtained as shown in FIG. Immediately after the start of pressing, as indicated by the temperature rise line 1, the temperature rises rapidly and reaches 97 to 99 ° C. This rising time is TM1. Thereafter, the horizontal temperature line 2 is maintained while maintaining a substantially constant temperature, and the temperature becomes 100 ° C. This horizontal temperature time is defined as TM2. When the temperature reaches 100 ° C., the shirt is dried, and thereafter, the temperature rise line 3 increases rapidly. That is, the temperature changes at points A and B. Hereinafter, the point A is called the first temperature change point, and the point B is called the next temperature change point. The sum of the rising time TM1 and the horizontal temperature time TM2 is the drying time TM. It has been found that this temperature rise characteristic is the same regardless of the timing when the air suction device is always on or always off or on. However, the drying time TM, particularly the rising time TM1, varies depending on the timing of the air suction device being turned on or always off or on.

From the results of tests 1, 2, and 3 in [Table 1] and the rising characteristics shown in FIG. 3, the time for turning on the air suction device is the first temperature change point A, and the time for turning off the air suction device is as follows. It has been found that the temperature change point B is preferably used as a reference.

[Embodiment]
An embodiment of a clothing finishing method and apparatus of the present invention will be described with reference to FIGS. The present embodiment shows a case where the present invention is applied to the clothing finishing apparatus of Patent Document 2. FIG. 1 is a block diagram of a clothing finishing apparatus including a control unit according to the present embodiment.

  In the garment finishing apparatus 10, a hot plate 12 is disposed above an ironing board 11 on which clothing is set. The ironing table 11 is provided on an iron support table provided so as to be movable up and down, and includes an ironing table for finishing the buttock of the shirt and an ironing table for finishing the sleeve. A hollow portion is formed in the iron support base, and this hollow portion is connected to the air suction device 13, and the air suction device 13 is driven by the air suction device motor 14. In the ironing table for finishing the buttock and the sleeve, the surface of the crimping plate is covered with a breathable pad material. The top plate of the crimping plate has a large number of air holes formed on the surface. The above configuration is the same as that of the prior art. In FIG. 1, 15 is an on / off switch of the air suction motor 14, and 16 is a start button of the apparatus.

  The air suction motor 14 is controlled by the control unit 20. The control unit 20 has a temperature measurement sensor 21, and the tip of the detection unit of the temperature measurement sensor 21 measures the temperature of clothes from the inside of the ironing board 11 of the clothing finishing apparatus 10. The temperature measured by the temperature measurement sensor 21 is input to the temperature change detection circuit 22. The temperature change detection circuit 22 is configured to output when the temperature changes.

  As described with reference to FIG. 3, when the temperature changes at the first temperature change point A and the temperature change point A is detected 23, the ON signal 23a is output and the air suction device 13 is driven. When the temperature change detection circuit 22 detects 24 the next temperature change point B, an off signal 24a is output. The off signal 24a acts as a signal for separating the heat plate 12 from the clothing and a signal for turning off the air suction motor 14. The signal for turning off the air suction motor 14 turns off the air suction motor 14 after a time preset in the timer 25.

  Here, as in Patent Document 2, when the ironing board 11 is alternately reversed at an angle of 180 degrees and positioned at the press position and the dressing position, the shirt after the press finish is rotated to the dressing position. The timer 25 is set so that the off signal 24b is input to the air suction motor 14 after a certain time (about 2 to 3 seconds) so as not to drop due to centrifugal force. In the garment finishing apparatus in which the press position and the dressing position are the same, the timer 25 may be set not to operate, but the timer 25 may be operated to cool the garment.

Next, the operation will be described with reference to FIG. In the present embodiment, clothing such as a shirt is set on the ironing board 11 of the clothing finishing apparatus 10 (step 30). Next, the on / off switch 15 of the air suction motor 14 is turned on (step 31). As a result, the clothes are held on the ironing board 11. Subsequently, when the start button 16 is pressed, the clothing finishing apparatus 10 starts (step 32). Thereby, the ironing board 11 raises and presses clothing against the hot platen 12 with a pressing force (air pressure) (step 33). The above process is the same as the conventional process.

  In the present embodiment, the on / off switch 15 of the air suction motor 14 is turned off (step 34). When the temperature measurement sensor 21 measures the temperature of the clothes (step 35) and the temperature change detection circuit 22 detects the temperature change point A 23 (step 36), an on signal 23a for turning on the air suction motor 14 is output. (Step 37). As a result, the air suction motor 14 is driven to operate the air suction unit 13 to suck the suction passage (step 38). And the hollow part of an iron support stand becomes a negative pressure, the surface of the iron stand 11 is air-sucked, and the water | moisture content of the clothing set on the iron stand 11 is sucked.

  When the temperature reaches 100 ° C. or higher and the temperature is dried, and the next temperature change point B is detected 24 (step 39) by the temperature change detection circuit 22, an off signal 24a is output (step 40). By this off signal 24a, the ironing board 11 of the clothing finishing apparatus 10 is lowered and the hot plate 12 is separated from the clothing (step 41). When the off signal 24a is output, the off signal 24b of the air suction motor 14 is output (step 43) after the set time of the timer 25 (step 42), and the air suction motor 14 is stopped (step 44). Thereafter, the shirt is removed from the ironing board 11 to complete the series of steps.

  Table 2 shows the results of experiments performed with the clothing finishing apparatus 10 provided with the control unit 20 shown in the present embodiment. Test 4 has the same conditions as those of Tests 1, 2, and 3, that is, a pressing force (air pressure) to the shirt of 0.7 MPa, a steam pressure of 0.5 MPa for blowing steam into the hot plate 12 (temperature of the hot plate 12 is 154 ° C.) The test was conducted under the conditions. Moreover, in order to make it the same conditions as Tests 1, 2, and 3, it was washed with one washing machine and dehydration was handled in the same time. Similarly to the average values of tests 1, 2, and 3, in order to eliminate measurement errors, one of the maximum value and the minimum value of the seven shirts is omitted, and the average value of the five shirts is shown. As apparent from [Table 2], the average value of the drying time TM in Test 4 was 17.8 seconds, and the drying time TM was significantly shortened compared with Tests 1, 2, and 3.

As described above, when the clothes are pressed with the heated hot plate 12, the temperature of the clothes rises from the start of the press, and when the temperature reaches a temperature within the temperature range of 97 ° C to 99 ° C (point A), the air suction device 13 is turned on and air is sucked, and then the press by the hot plate 12 is released at the temperature change point B where the temperature has changed , and the air suction device 13 is turned off based on this temperature change point B. Significantly shortened and improved production efficiency. That is, since the air suction device 13 does not operate until the detection 23 when the temperature is in the temperature range of 97 ° C. to 99 ° C. (point A) , the clothing is not cooled by the air suction device 13. The temperature of the garment reaches a temperature near drying of 97 to 99 ° C. with a rise time TM1 (about 10 seconds). Thereafter, the air suction unit 13 is turned on and drying is performed, so that the drying time is remarkably shortened and the production efficiency is improved. Further, since the press is released at the next temperature change point B, heat is not applied to clothing more than necessary, and buttons and fabrics are not damaged.
