Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trim cover for covering a seat surface, and more particularly to a trim cover for a seat which has a leather portion and a non-leather portion and is sewn in a bag shape. It relates to a method and an apparatus for removing.

[0002]

2. Description of the Related Art At present, in automobile seats, a cushion pad base made of a synthetic resin foam such as molded urethane is cut according to its shape and covered with a bag-shaped sewn trim cover, and is manufactured. There are many things. There are various types of trim covers, some of which are sewn fabric and leather.

FIG. 6 is a view schematically showing an example of an automobile seat using the trim cover. The seat back 1 shown in FIG. 1 has a structure in which a cushion pad base (not shown) is disposed inside and a trim cover 2 covers the outside. As shown in FIG. 7 as an enlarged schematic cross-sectional view of a portion A in FIG. 6, the trim cover 2 has a leather portion 3 made of pure leather and a non-woven fabric made of, for example, a fabric such as a fabric in accordance with the shape of the base of the cushion pad. The leather part 4 is cut and sewn at a part 5. Note that a backing material 6 such as a backing fabric is integrally formed on the back surface (inside) of the leather portion 3 and the non-leather portion 4, respectively.

[0004] Such trim cover 2 is usually liable to generate large and small wrinkles during sewing processing or in the process of being conveyed to an assembly line. If wrinkles are formed, not only the appearance of the product after seat assembly is impaired, but also the seating comfort is reduced. May also have an effect. Therefore, conventionally, the trim cover 2 is inspected in a sheet assembling process or the like, and an operation of removing wrinkles is performed as necessary. However, in this wrinkle removal work,
In the trim cover 2 in which the leather portion 3 and the non-leather portion 4 are mixed, steam press cannot be performed while injecting steam as in a normal steam iron. This is because the quality of the leather portion 3 is easily deteriorated by the steam. Accordingly, in the conventional method, for example, in an assembly line, wrinkles formed on the leather portion 3 are rubbed while hot air is blown by a dryer 7 as shown in FIG. The wrinkles generated in 4 are dealt with by applying a small steam iron 8 for exclusive use. This wrinkle removing method is the same for the seat cushion 9. Usually, this kind of trim cover 2 is handled in a state where both the sewing and the transporting steps are turned upside down, and the trim cover 2 is put into the sheet assembling process while being turned upside down, and is turned upside down in the process of assembling to the cushion pad base. Is arranged in a normal state while being inverted from the other.

[0005]

As described above, in the trim cover 2 in which the leather portion 3 and the non-leather portion 4 are mixed, the conventional operation of removing wrinkles after sewing in a bag shape is performed individually. It depends on the manual work performed in the current situation. The wrinkles of the leather portion 3 are time-consuming, cumbersome, and require a lot of power because the operator rubs the wrinkles while applying hot air to each of the wrinkles. Also,
If wrinkles occur in both the non-leather part 4 and the leather part 3,
Since the wrinkle portion of the non-leather portion 4 must be dealt with by using the steam iron 8 and the wrinkle portion of the leather portion 3 has to be dealt with by the dryer 7 without steam, there is a problem that workability is poor. .

[0006] The present invention has been developed in view of the above problems. An object of the present invention is to provide a method and an apparatus for removing wrinkles in a sheet trim cover which can eliminate the above-mentioned problems, have a relatively simple structure, and can remove optimal wrinkles. Still other objects will be sequentially clarified in the contents described below.

Therefore, based on the flowchart of FIG. 3, the operation of the present embodiment will be described with reference to FIGS.
This will be described next.

First, before setting the trim cover 2 for removing wrinkles, the pressing pad 13 is attached to the air cylinder 26.
Is located at the “non-press position”, and is largely separated from the corresponding hanger members 12s, 12m. Also,
The hanger member 12m is disposed at the “temporary holding position” by the air cylinder 20, and the hanger member 12s
And approaching. In this state, the two hanger members 12s, 12m can be inserted into the bag shape of the trim cover 2 turned over, and the trim cover 2 can be set on each hanger member 12s, 12m. FIG. 1 shows the trim cover 2 having a pair of hanger members 12s and 12m.
FIG. 4 shows a state in which the trim cover 2 is set on the hanger members 12s and 12m and temporarily held.

After the trim cover 2 has been set in this way (step ST1), when the start switch (not shown) is turned on by depressing the switch pedal 10, the air cylinder 20 is driven via the cylinder drive unit 33. . Then, the hanger member 12m is moved from the “temporary holding state position” to the “holding state position”, and the bag-shaped trim cover 2 is strongly stretched from the inside to the outside with the pair of hanger members 12s and 12m (step ST2). ). That is, in this state, the hanger members 12s and 12m hit the non-leather portions 4 on both sides, and the leather portions 3 are strongly pulled together with the non-leather portions 4 in the width direction. Next, hot air is sent into the trim cover 2 from the hot air blower 23 through the hot air duct 22 via the hot air supply means control unit 36. Further, when the leather portion 3 under a predetermined tension is heated by hot air, the wrinkles in the portion mainly including the leather portion 3 ((This is theoretically not limited to the wrinkles of the leather portion 3 but non-wrinkles. (This means that small wrinkles or the like of the leather portion 4 may be included.) (Step ST3) In addition, the discharge position of the warm air duct 22 is, for example, a forward and backward movement in the trim cover 2, that is, the leather. It is more preferable that the leather portion 3 can be adjusted so that hot air can be blown onto the leather portion 3 while moving in the trim cover 2 in accordance with the position of the portion 3.

At the same time, the air cylinders 26 are respectively driven via the cylinder driving units 34, and the respective pressing pads 13 are moved from the "non-press position" to the "press position".

The steam is blown out from the steam discharge hole 27, and a steam press is performed between the steam and the pressing pad 13 to remove wrinkles in the non-leather portion 4 (step ST5). In this regard, in terms of the steam discharge mode here, for example, the steam is not discharged from all of the large number of steam discharge holes 27 at the same time, but is discharged only from the steam discharge holes 27 at a partial position.
It is more preferable that the position is also switched so that discharge can be performed according to an arbitrary portion of the non-leather portion 4.

The supply of the hot air and the supply of the steam are performed for a predetermined time (usually several seconds). When the set time has elapsed, the supply of hot air and the supply of steam are stopped via the hot air supply means control unit 36 and the steam supply means control unit 37 (steps ST6 and ST7). Next, the air cylinders 26 are driven via the cylinder driving units 34, respectively, and the pressing pad 13 is moved from the "press position" to the "non-press position" to release the pressing (step ST8). The air cylinder 20 is driven via the portion 33 to move and return the hanger member 12m from the “holding position” to the “temporary holding position” to return to the trim cover 2.
Is released (step ST9). Thereafter, the trim cover 2 is removed from the hanger members 12s, 12m.
Thereby, the trim cover 2 from which wrinkles in the leather portion 3 and the non-leather portion 4 have been removed is obtained. By setting a new trim cover 2 on which the next wrinkle removal process has not been completed on the hanger members 12s, 12m, the wrinkle removal process can be performed in the same manner.

Therefore, according to the above embodiment, the pair of hanger members 12 s and 12
m, the trim cover 2 is temporarily held on the hanger members 12a, 12b, and then the hanger members 12a, 12b
