Abstract

<P>PROBLEM TO BE SOLVED: To finish a shirt beautifully so that a sleeve is not creased unnecessarily, in a technique for finishing the shirt, such as a technique for finishing it three-dimensionally. <P>SOLUTION: A shirt finishing device 1 is provided with a body model 5 whereon the body portion of the shirt 4 is put and hot air is blown into the sleeve 4b of the shirt 4 to finish the sleeve 4b. In this device, support arms 10 standing upward are provided on both the right and left sides of the body model 5 and sliders 11 holding the end parts of the sleeves 4b and sliding in the direction of stretching the sleeves 4b are provided at the upper end parts of the support arms 10, while stretching means 19, 21, 22 and 24 pulling the sleeves 4b by a force equaling the tension of the sleeves 4b stretched by the strike of hot air blown inside the sleeves are connected to the sliders 11. Since the force giving a stretch to the sleeves 4b on the occasion of finishing equals to the tension stretched by the strike of the hot air as stated above, the shirt is prevented from being creased by the usual predominance of the force giving the stretch. Since there is an allowance for generation of the tension even by the strike of the hot air, a pretty finish free from an unnatural crease due to the stretch can be attained and the work for small adjustment becomes unnecessary. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a shirt finishing technique for, for example, three-dimensional finishing of a shirt, and more particularly, to a shirt finishing method and apparatus capable of finishing a shirt sleeve more beautifully.
[0002]
[Prior art]
As shown in FIG. 9, the three-dimensional finishing device for a shirt has a human body 101 corresponding to the torso of a human body standing on a base 102 and pulling sleeves 103 on both left and right sides of the human body 101. The pull arm 104 is provided and configured. The human body 101 is press-finished with a trowel and, on both sides, hot air is blown into the pulled sleeve 103 to dry-finish the sleeve 103.
[0003]
By the way, in such an apparatus, the pulling arm 104 is formed in a branch shape extending obliquely upward from the base 102, and its base end is rotatably supported in the base 102 (for example, see Patent Reference 1).
[0004]
That is, the pulling arm 104 moves in a fan shape, and the sleeve 103 is pulled by instigating the pulling arm 104 in a direction in which the pulling arm 104 is tilted.
[0005]
According to this configuration, the sleeve 103 can be reliably pulled. However, in addition to the force of the mechanism for instigating the pull arm 104, the sleeve 103 is fully pulled using the weight of the pull arm 104 itself. As shown in FIG. 9, wrinkles are formed on the sleeve 103 of the shirt, particularly on the base end.
[0006]
Since the finishing process is performed in a state where the wrinkles are formed, wrinkles remain in the finished shirt. For this reason, it has to be corrected later.
[0007]
Further, since the sleeve 103 is pulled more than necessary, the shirt may be damaged.
[0008]
Further, since the pull arm 104 pivots in a fan shape, there is a great difference in the angle of the pulled sleeve 103 between the long shirt and the short shirt having the sleeve 103. That is, if the sleeve 103 is long, it is pulled downward, so the angle between the sleeve 103 and the body part is small, but if the sleeve 103 is short, it is not pulled much, so the angle between the sleeve 103 and the body part is large. Considering that the length of the sleeve 103 of the shirt is various, it is easy to imagine that considerable variation occurs, and pulling the 103 easily causes the wrinkles as described above. It also causes a poor looking finish.
[0009]

[0010]
[Problems to be solved by the invention]
Therefore, it is a main object of the present invention to provide a more beautiful finish.
[0011]
[Means for Solving the Problems]
Means for this is a shirt finishing method of applying tension to the sleeve of the shirt and performing finishing by applying hot air, wherein the tension is applied with a force that opposes the tension of the sleeve that is stretched against hot air. The method is characterized by:
[0012]
In other words, when hot air is applied to the sleeve while tension is applied to the sleeve, or when hot air is applied to the sleeve to apply tension to the sleeve, the tension generated by the hot air stretching the sleeve and the pulling force applied to apply tension to the sleeve are opposed. In other words, they are almost equal and compete with each other. For this reason, the force for imparting tension to the sleeve exceeds the tension generated in the sleeve, so that no extra wrinkles are formed, and finishing can be performed without such wrinkles.
[0013]
The force that antagonizes the tension of the sleeve is applied by extending the sleeve once to the maximum length and then contracting it.The application of force that antagonizes the tension of the sleeve is performed by the operation of the fluid cylinder, and the sleeve is once extended to the maximum length. After the expansion, the fluid cylinder may be set in a non-pressurized state. By stretching it to its maximum length and then shrinking, you can make room for the sleeve with hot air.
[0014]
Further, the application of a force that antagonizes the tension of the sleeve may be performed with a strength corresponding to the properties of the cloth constituting the sleeve. The properties of the dough are, for example, the thickness and constituent fibers of the dough, properties and conditions such as the amount of ventilation, and, for example, the thinner and coarser the dough is such that even when hot air is blown, the hot air is immediately discharged through the dough. Apply tension with weak force.
[0015]
In this case, as described above, after the sleeve is once extended to the maximum length, the sleeve may be contracted, or the fluid cylinder for applying the tension may be in a non-pressurized state.
[0016]
Another means is a shirt finishing apparatus for providing a human figure for wearing a torso part of a shirt, and blowing hot air into a sleeve of the shirt worn on the human figure to finish the sleeve. A support arm that rises upward, and a slider that slides in the direction in which the sleeve is extended while holding the end of the sleeve is provided at the upper end of the support arm. The present invention is characterized in that the shirt finishing device is connected to an extension means for pulling the sleeve with a force opposing the tension of the sleeve to be stretched.
[0017]
That is, the end of the sleeve of the shirt worn in a human body shape is held by a slider provided at the upper end of the support arm, and this slider is slid by an extension means to pull the sleeve to give tension to the sleeve and to apply hot air. Blow out into the sleeve. Then, the tension generated when the sleeve is stretched by the hot air and the pulling force by the stretching means antagonize, that is, substantially equal, and the sleeves are stuck to each other. For this reason, the force for imparting tension to the sleeve exceeds the tension generated in the sleeve, so that no extra wrinkles are formed, and finishing can be performed without such wrinkles.
[0018]
In addition, a slide rail inclined at a predetermined angle may be provided at an upper end of the support arm so that the slider slides at an angle at which the sleeve of the shirt worn in a human body shape naturally extends. The pulling (tensioning) of the sleeve can be performed very naturally irrespective of the length of the sleeve.
[0019]
The stretching means for applying the tension may be constituted by a fluid cylinder, and the fluid cylinder may be controlled so as to extend the sleeve once to a maximum length and then contract. For example, control is performed using a sequencer, or a sensor is incorporated and configured. Further, it is also possible to realize the fluid cylinder by controlling the fluid cylinder so that the sleeve is once expanded to the maximum length and then put in a non-pressurized state without actively contracting.
[0020]
Furthermore, a pressure adjusting means and a pressure changeover switch are connected to the stretching means for applying a force opposing the tension of the sleeve, and can be selectively switched so as to stretch with a strength according to the properties of the fabric constituting the sleeve. It may be. The properties of the dough are, for example, the thickness and constituent fibers of the dough, properties and conditions such as the amount of ventilation, and, for example, the thinner and coarser the dough is such that even when hot air is blown, the hot air is immediately discharged through the dough. Apply tension with weak force.
[0021]
In this case, it is also possible to additionally provide a structure in which the sleeve is contracted once or stretched to the maximum length, and then the fluid cylinder for applying the tension is put in a non-pressurized state.
[0022]
【The invention's effect】
As described above, according to the present invention, the force for applying tension to the sleeve at the time of finishing is a force that antagonizes the tension of the sleeve that is applied by hot air. No wrinkles are formed. Since there is room for tension to be generated even by contact with hot air, a beautiful finish free from unnatural pull wrinkles can be achieved, and the necessity of rework is eliminated.
[0023]
The application of a force that opposes the tension of the sleeve stretched by the hot air can be performed by expanding the sleeve once to its maximum length and then contracting or receiving the force of the hot air blow to allow the sleeve to slide freely (no pressure applied). The configuration is simple and no special device is required, so that effects such as cost reduction can be obtained.
[0024]
In addition, if the force is applied with a strength according to the properties of the fabric constituting the sleeve, the sleeve will not be pulled as much as possible, so there is no risk of damaging the shirt as in the past, and a beautiful finished state can be obtained So good.
[0025]
By applying such a force in accordance with the properties of the dough in combination with the above-described configuration in which the fabric is contracted or set in a free state, a better finished state can be obtained.
[0026]
Furthermore, if the slider that slides to give tension to the sleeve is slid at an angle at which the sleeve of the shirt naturally extends, both the long and short sleeves can be stretched at a natural angle as well, so that a more complete A beautiful finish is possible.
[0027]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a front view of the shirt finishing apparatus 1, and FIG. 2 is a side view thereof. As shown in these figures, the shirt finishing apparatus 1 has a shirt 4 (FIG. (See FIG. 3), a body part 5 for wearing the body part 4a is erected, and stretching mechanisms 6 and 6 for extending the sleeve 4b of the shirt 4 are arranged on both left and right sides of the body part 5. That is, the torso part 4a of the shirt 4 is press-finished using the human body 5, and the sleeve 4b is stretched using the stretching mechanism 6, and is dried and finished with hot air blown through the human body 5 to the inside.
[0028]
The torso 5 is erected on the front side of the base 3, a back side iron 7 is provided on the back side of the torso 5 to approach and separate from the torso 5, and on the front side of the torso 5, A front-side iron 8 that comes in contact with and separates from the front of the human body 5 is provided. The front-side iron 8 is mounted via a left-right movement mechanism 9 so as to slide in the left-right direction. The left and right mechanism 9 may be configured using two slide rails 9a and an air cylinder 9b as shown.
[0029]
On the back side of the human figure 5, supporting arms 10 and 10 are provided, which stand upright on both the left and right sides of the human figure 5 when viewed from the front, and a part of the extension mechanism 6 is provided at the upper end of these supporting arms 10. A constituent slider 11 is provided.
[0030]
As shown in FIG. 3, the slider 11 is provided with an extension portion 12 extending horizontally forward, and an end of the sleeve 4b, that is, a cuff portion, is provided at the tip of the tip of the extension portion 12. The holding portion 13 for holding 4c is continuously provided. The holding portion 13 includes a narrow plate-shaped connecting portion 13a that is long in the left-right direction, a plate-shaped pressing table 13b that is arranged in parallel with the connecting portion 13a at appropriate intervals, and an outer end of the pressing table 13b. And the clamp 13c provided. That is, a clamp 13c is provided at the base of the press table 13b having a free end formed in an arc shape in a plan view to hold and hold the cuff portion 4c of the shirt 4. The press table 13b is formed by covering a cloth or the like, and the clamp 13c is composed of a pair of pressing members 13e provided with a gripping air cylinder 13d to enable pressing and opening.
[0031]
Further, the extension portion 12 is provided with an upper iron 14 and a lower iron 15 for pressing and finishing the tack near the cuff portion 4c of the sleeve 4b using the clamp 13c. The upper iron 14 and the lower iron 15 are provided with heaters 14a and 15a, and are configured to be brought into contact with and separated from both front and back surfaces of the press table 13b. The opening and closing operation for contact and separation is performed by the press air cylinder 16.
[0032]
The slide plate 17 at the base end of the slider 11 having such a configuration is slidably supported on a slide rail 18 as shown in FIG. The extension means forming a part of the extension mechanism 6 for driving the slide plate 17 to slide to pull the sleeve 4b is constituted by an extension air cylinder 19. The base of the extension air cylinder 19 is fixed to a support member 20 having the slide rail 18, and the piston rod 19a of the extension air cylinder 19 is fixed to the slide plate 19a.
[0033]
The support member 20 is integrally attached to the upper end of the support arm 10, and is attached such that the sleeve 4b of the shirt 4 is inclined so as to extend naturally. The angle may be, for example, about 15 degrees.
[0034]
The extension air cylinder 19 is a three-position cylinder having a built-in intermediate stop mechanism. That is, as shown in FIG. 3, there are three types of positions: a full stroke position where the piston rod 19a is pushed out most, an intermediate stroke position where the piston rod 19a is slightly pulled out from the pushed position, and an initial (retracted) position. Is driven. The retracted length to the above-mentioned intermediate stroke position is a length that can provide a margin for stretching the sleeve 4b extended to the maximum length by blowing hot air, and may be, for example, about 1 to 2 cm.
[0035]
The drive control of each unit including the extension air cylinder 19 is performed by a sequencer.
[0036]
Next, this control operation will be described.
When the cuff portion 4c at the end of the sleeve 4b is held by the clamp 13c and the operation switch is turned on, the sequencer expansion / contraction air cylinder 19 is driven, and the piston rod 19a is moved toward the full stroke position at a predetermined pressure. Extrude. After the sleeve 4b is extended to the maximum length and the piston rod 19a stops, the air from the blower 2 is superheated by a heater (not shown) to generate hot air, which is blown into the sleeve 4b through the human body mold 5. Then, in synchronization with the blowing of the hot air, the extension air cylinder 19 is driven to retreat the piston rod 19a to the intermediate stroke position. At the time of the retreat, the force for applying tension to the sleeve 4b by the extension air cylinder 19 is opposed to the tension of the sleeve 4b which is stretched by hot air.
[0037]
On the other hand, for the tack near the cuff portion 4c of the sleeve 4b, the press air cylinder 16 is driven to perform press finishing with the upper iron 14 and the lower iron 15.
[0038]
After blowing the hot air for a predetermined time, the blowing of the hot air is stopped, the press air cylinder 16 is returned to the initial state, and the piston rod 19a of the expansion air cylinder 19 is returned to the initial position. Also, the gripping air cylinder 13d is returned to the initial state, and the cuff portion 4 is opened.
[0039]
In this way, when the sleeve 4b is finished, the sleeve 4b is once extended to the maximum extent and then temporarily contracted, so that the force for applying tension to the sleeve 4b and the force for applying the hot air are opposed to each other to make room for expansion by the hot air. Therefore, it is possible to suppress the occurrence of tension wrinkles due to excessive stretching. Then, since the finishing can be performed in this state, it is possible to perform the finishing which is beautiful and does not require any rework.
[0040]
In addition, since the provision of the allowance is performed after the sleeve 4b is once pulled to the maximum length, the overall shrinkage can be increased, fine wrinkles can be easily extended, and the drive control can be easily performed. .
[0041]
Further, since the slider 11 slides on the slide rail 18 inclined at a predetermined angle, as shown in FIG. 5, even if the shirt 4 is long or short, The finishing can be performed by extending the angle to the correct natural angle as the shirt 4. This also gives a beautiful finish without wrinkles.
[0042]
FIG. 6 shows another example of the expansion means. As shown in this figure, expansion is not performed by one air cylinder as described above, but is performed by two return air cylinders (first expansion air cylinder). 21, the second extension air cylinder 22) may be combined to be driven to the three types of positions as described above.
[0043]
That is, the first extension air cylinder 21 is attached to the base of the support member 20, and the second extension air cylinder 22 is connected to the piston rod 21 a of the first extension air cylinder 21. The slide plate 17 is attached to the piston rod 22a of the cylinder 22. Then, the retracted length of the first extension air cylinder 21 is set to be a length necessary for contracting the sleeve 4b.
[0044]
Note that the same components as those in the previous example are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0045]
Alternatively, the extension of the sleeve 4b to the maximum length may be detected using the sensor 23 as shown in FIG. 7, and based on this detection, control may be performed to retract the piston rod of the air cylinder for extension. . The sensor 23 is provided, for example, at an appropriate position on the press table 13b so as to detect the longitudinal end portion of the set cuff portion 4c. The sensor 23 may be constituted by appropriate means such as a photoelectric sensor. The operation switch is set to be turned on when the sensor 23 is outputting a signal indicating that the cuff portion 4c is present, and the press table 13b is moved by the driving of the device to extend the sleeve 4b to the maximum length. When the portion 4c is displaced in the direction of coming off from the press table 13b and the signal from the sensor 23 outputs a cuffless signal, the piston rod of the air cylinder for extension is moved to the intermediate position for allowing room for tension by hot air. Control is performed to retreat to the stroke position.
[0046]
Furthermore, without retracting the piston rod of the air cylinder for extension as in each of the above-mentioned examples, without supplying pressurized air to the air cylinder for extension, that is, in a non-pressurized state, to blow out hot air. Accordingly, a state in which the piston rod can be retracted may be created.
[0047]
Further, it is also possible to configure so that the tensile strength can be appropriately selected according to the properties of the cloth constituting the sleeve 4b. That is, as shown in FIG. 8, a pressure regulator 26 is connected to a switching valve 25 that supplies pressurized air to the extension air cylinder 24, and a pressure switch 27 is connected to the pressure regulator 26. Connected and configured so that the force to stretch the sleeve 4b can be applied by the force that opposes the tension of the sleeve 4b stretched by hot air according to the thickness of the fabric, the roughness of the eye, the quality of the fiber, the air permeability, etc. I do.
[0048]
With this configuration, tension can be applied to the sleeve 4b with more appropriate force, and a beautiful finish can be expected. In addition, inconvenience such as damaging the shirt 4 can be avoided.
[0049]
In addition, by incorporating the configuration of the tensile strength selection into the configuration of retracting or applying no pressure as in the above-described example, a synergistic effect of these is created, and a gentler finish is possible, and a beautiful finish is obtained. realizable.
[0050]
Each of the above examples is an embodiment of the present invention,
The extension air cylinders 19 and 24, and the first extension air cylinder 21 and the second extension air cylinder 22 correspond to the extension means of the present invention.
The present invention is not limited only to the above-described configuration.
For example, it can also be finished in a plane without the human figure 5.
