Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method of manufacturing a fabric trim having a generally inverted U-shaped cross section and having a decorative fabric adhered to the outer peripheral surface.

<Prior Art and its Problems> Conventionally, when manufacturing cloth trim, the following procedure has been carried out (see JP-A-62-222834, JP-A-63-78737, etc.).

First, a substantially flat trim body is formed by extrusion-molding rubber or the like around a metal insert.

After vulcanization, a predetermined adhesive is applied to a predetermined position of the trim body using a roller or the like, and the decorative cloth is continuously attached.

Thereafter, the cross section was bent into a substantially inverted U-shape to sequentially manufacture cloth trims of a predetermined shape.

However, in the production of conventional upholstered trims, the decorative fabric is bent after being attached, which causes the decorative fabric to stretch at the corners of the trim cross section. Therefore, the density of the nap of the decorative fabric decreases in the corners of the trim cross section,
There is a risk that the appearance of the trim will be degraded or that the decorative fabric at the corner of the trim cross section will be torn when the trim is bent and attached to a predetermined location.

The present invention solves the above-mentioned problems, and aims to provide a fabric trim manufacturing method that can prevent deterioration in appearance and prevent the decorative fabric from tearing even if it is bent during installation. .

<Means for Solving the Problems> A method for manufacturing a cloth trim according to the present invention is a method for manufacturing a cloth trim having a generally inverted U-shaped cross section and having a decorative cloth adhered to the outer surface, the method comprising: (a) ) A trim body forming step of forming a substantially flat trim body by covering the insert with an elastic polymer material by extrusion molding; (b) A bending process of bending the trim body to form a substantially inverted U-shaped cross section. (C) an adhesive application step of applying an adhesive to a predetermined position of the bent trim body; (d) a cloth covering step of pasting a decorative cloth on the trim body coated with the adhesive. Features.

<Operations and Effects of the Invention> In the fabric trim manufacturing method according to the present invention, before pasting the decorative cloth, the trim body formed into a substantially flat plate shape by extrusion is pre-bent, and its cross section is shaped into a substantially inverted U shape. After shaping, adhesive is applied in place and decorative fabric is applied to produce an upholstered trim.

Therefore, in the fabric trim manufacturing method according to the present invention, the decorative fabric is pasted on the trim body whose cross section has already been bent into a substantially inverted U-shape, whereas the conventional manufacturing method involves bending after pasting the decorative fabric. Compared to this, the decorative fabric of the upholstered trim is not stretched, and there is less change in the density of the nap of the upholstered fabric, which prevents the appearance of the upholstered trim from deteriorating. Also,
Even if the manufactured fabric trim is bent and attached to the specified location,
Since the decorative fabric has little pre-stretching, tearing of the decorative fabric can be prevented.

<Example> Hereinafter, one embodiment of the present invention will be described based on the drawings.

The devices used in the finishing process (2) include a caulking machine 14 that performs fine-adjustment bending on the cross section of the final product shape as shown in Figure 's2, and a cutting machine that cuts to a predetermined length to produce the upholstered trim 1. It is machine 15. These caulking machine 14 and cutting machine 1
5 is a known device.Next, the process of manufacturing the upholstered trim 1 on this manufacturing line will be explained.

First, in the trim body forming process I, the insert 2a
The trim main body 2 having a substantially flat cross-section as shown in FIG. 3 is extruded by the extruder 4 which is drawing in the trim body 2.

Then, in the vulcanization step H, the substantially flat trim body 2 is vulcanized in the vulcanization tank 5 and cooled in the cooling tank 6.

Thereafter, in the bending process (i), the trim body 2 is formed by the bending machine 7 to have a substantially inverted U-shaped cross section as shown in FIG.

Then, in the adhesive application step I11, the brimer P is applied to a predetermined portion by the brimer applicator 8, and after cooling in the air cooling tank 9, the brimer P is applied to the predetermined portion by the brimer applicator 10, as shown in FIG. Adhesive B is applied to the location and dried in a drying oven 11.

At this time, when applying the brimer P, the brimer P is applied to the trim body 2 by the brimer applicator 8 in the following manner (see FIGS. 6 and 7).

In addition, when the trim body 2 is guided and held by the guide blocks 42 and 43 and conveyed, a predetermined start switch of the control device 40 is turned on, and the hose 27 that has been blocked by the presser roller 34 is opened. The brimer P is made to drip onto the trim body 2 from the nozzle 28.

The brimer P dripped from the nozzle 28 of the hose 27 is initially stored in the tank 21 and flows out from the lower cylindrical portion 22 into the saucer 25. At that time, since the tank 21 is sealed and the cylindrical part 22 of the tank 21 is inserted into the saucer 25 which is open at the top, the brimer P in the saucer 25 adjusts the height of the liquid level to the lower end of the cylindrical part 22. It is adjusted so that it approximately matches the position of . Therefore, the hose 27, which has one end disposed below the liquid level of the saucer 25, has a certain amount of brimer P depending on the height difference between the liquid level of the brimer P on the saucer 25 and the nozzle 28 on the other end side of the hose 27. , nozzle 2
Try to drip from 8.

Incidentally, this difference in height can be adjusted by adjusting the height position of the tank 21 and saucer 25 with respect to the holding frames 23 and 26,
The insertion depth of the cylindrical portion 22 into the tank 21 may be adjusted.

A flow rate regulator 29 is disposed at an intermediate portion of the hose 27 to adjust the flow rate of the brimer P by pressing the hose 27 with a presser roller 34.
By this adjustment, the flow rate of the brimer P dripped from the nozzle 28 of the hose 27 is finely adjusted.

Therefore, when applying the primer P, the primer P is applied dropwise, and the amount of the dripping is controlled by adjusting the height of the liquid level of the primer P in the saucer 25 and adjusting the flow rate regulator 29 at the intermediate portion of the hose 27. Since it can be adjusted in two stages and is finely adjusted, it is possible to drip and apply the brimer P accurately onto the trim body 2 without waste, and the yield of the brimer P applied to the trim body 2 can be reduced. can be improved. By the way, in the case of the example, the amount of Braimer P used was reduced by about 17% compared to the dipping method.
I was able to make it to 8.

In the primer coating device 8 of the embodiment, when the viscosity of the primer P changes, for example, when the viscosity becomes high, the control device 40 controls the primer coating to be applied onto the trim body 2 based on the electric signal input from the sensor 38. In other words, the motor shaft 36 is rotated by a predetermined angle in a predetermined direction so as to count the number of drops of Brimer P per unit time and maintain the number of drops of Brimer P dripped from the nozzle 28 per unit time at a predetermined number. Then, the presser roller 3 of the flow rate regulator 29
A predetermined electric signal is output to the servo motor 35 so that the opening shape of the hose 27 at the portion held by the hose 4 can be widened. Therefore, in this brimer application device 8, even if the viscosity of the brimer P changes, it is possible to automatically apply a certain amount of the brimer P to the trim body 2 in accordance with the viscosity.

Furthermore, when applying the adhesive B, the adhesive B is applied to the trim body 2 by the adhesive applicator 10 in the following manner (
(See Figures 8-9).

First, the trim main body 2 which has been bent to some extent by the bending machine 7 is sequentially conveyed by the take-up machine 16 and the take-up roller 56, and in the bending machine 50, the trim body 2 is bent to a certain extent by the guide block 5.
5 and the upper, lower, left and right rollers 51, 52, 5.
It will pass between 3 and 54. At this time, the opening width of the side wall portions 2B, 2C of the trim body 2 is regulated to a predetermined size by the processed surfaces 53a, 54a of the rollers 53, 54.

In the adhesive dripping device 60, the trim body 2 is moved to the positioning guide 7 while maintaining a predetermined cross-sectional shape.
3.74, it will pass through a predetermined trajectory.

At that time, between the positioning guides 73 and 74, each nozzle 63A, 63B, and 6
Adhesive B1/B with predetermined properties dripping from 3C/63D
2, B3, and B4 are automatically applied, and the application work can be performed efficiently.

In addition, the adhesives B1, B2, B3, and B4 dripped from each nozzle 63A, 63B, 63C, and 63D are
3 is arranged around the vicinity of the trim body 2,
It is reliably applied to the trim body 2 and is not wasted.
Furthermore, since the adhesive B is applied immediately after the trim body 2 is bent by the bending machine 50, the cross-sectional shape of the trim body 2 maintains a predetermined shape, and the periphery of the trim body 2 is The adhesive B dripped from each nozzle 63 arranged at a predetermined position is applied to a predetermined position on the outer surface of the trim body 2 accurately without waste, and with a uniform coating. By the way, in the case of the example,
The film thickness of adhesive B is approximately uniform within the range of 15 to 85 microns.
could be applied to. In addition, each adhesive B1-B2
If B3/B4 is spray applied, trim body 2
The consumption amount was 18 g per 111 of the trim body 2, but in the case of the example, the consumption amount was only 6.5 g per 111 of the trim body 2, and the yield could be significantly improved.

After that, in the upholstery step V, as shown in FIG.
The decorative cloth 3 is pasted on the surface of the trim body 2 by a cloth covering device 12, and passed through a curing furnace 13 to complete the pasting state of the decorative cloth 3.

The decorative cloth 3 is sometimes applied to the trim body 2 by the upholstery device 12 in the following manner (see Figures t1 to 14).

In addition, when the trim body 2 is initially sent to the upholstery device 12 through a predetermined production line, each air cylinder 100, 104, 109, and 114 is activated in advance, and those cylinder rods 1o! - Contract or expand rollers 105, 110, and 115 to separate each roller 92 to 96 from the trim body 2; The decorative fabric 3 from 81 is fed out via the feed roller group 82, the pressing member 86, the guide roller 87, and the guide 84, and the pressing is performed on the trim body 2 from the side roller 92 of the device 90 to the auxiliary end roller 96. The cylinder rods 101, 105, 110, and 115 are manually pasted at predetermined positions on the outer circumferential surface of the rods, and then the air cylinders 100, 104, 109, and 114 are sequentially operated to extend and retract each cylinder rod 101, 105, 110, and 115. Each of the rollers 92 to 96 is pressed to a predetermined position on the outer peripheral surface of the trim body 2 with the decorative cloth 3 interposed therebetween. Then, the transportation of the trim body 2 is restarted, and
The motor 83 of the cloth feeding device 80 is started, and the decorative cloth 3 is successively applied to predetermined positions on the outer peripheral surface of the trim body 2.

At this time, in the fabric feeding device 80, the decorative fabric 3 is moved to the trim body 2 by the drive roller 82m of the feeding roller group 82.
The trim body 2 is fed out from the decorative fabric roll 81 in accordance with the conveyance speed of the trim body 2, and arranged along the conveyance direction of the trim body 2 by the guide 84. At this time, the decorative cloth 3 is pressed by the pressing member 86 disposed between the feed roller group 82 and the guide 84, and is placed so as to be prevented from loosening.

Then, the decorative cloth 3 sent from the cloth feeding device 80 is first pressed in the pressing device 90, as shown in FIG.
The trim body 2 is pressed by the horizontal rollers 92 against the surfaces of the horizontal wall portion 2A and the side wall portion 2B of the trim body 2 being conveyed. that time,
Adhesive B is applied in advance to the surfaces of the horizontal wall portion 2A and the side wall portion 2B, and the horizontal roller 92 is rotatable.
Since the decorative cloth 3 has an external shape corresponding to the cross-sectional shape of the trim body 2 from the sponge portion 2C through the side wall portion 2A to the middle of the side wall portion 2B, the decorative cloth 3 is connected to the side wall portion 2A and the side wall portion 2.
It will be neatly attached to the surface of B without any gaps.

Thereafter, as shown in FIG. 13, the decorative cloth 3 is pressed against the surface of the sponge portion 2c of the trim body 2 by the vertical rollers 94. At this time, since the vertical roller 94 is rotatable and has an outer shape corresponding to the cross-sectional shape of the smoothing portion 2c of the trim body 2, even if the sponge portion 2c is soft, the decorative cloth 3 It is neatly pressed onto the surface of the surface without any gaps.

Further, as shown in FIG. 14, the terminal roller 95
As a result, the decorative cloth 3 is pasted from the sponge portion 2c of the trim body 2 to the inner peripheral surface of the side wall portion 2C. At that time, the adhesive B is applied in advance from the sponge portion 2c to the inner circumferential surface side of the side wall portion 2C, and the terminal roller 95 is rotatably attached to the sponge portion 2C in the trim body 2.
Since the decorative cloth 3 has an external shape corresponding to the cross-sectional shape extending from c to the inner circumferential surface of the side wall portion 2C, the decorative cloth 3
It will be neatly attached to the inner circumferential surface of the side wall portion 2C without any gaps.

Furthermore, in the case of the embodiment, a plurality of auxiliary lateral rollers are provided in front of the lateral roller 92 and the terminal roller 95 in the conveying direction of the trim body 2, respectively, and have the same external shape as the lateral roller 92 and the terminal roller 95, respectively, and have the same function. 93 and auxiliary terminal roller 9
6 is arranged, the decorative cloth 3 can be reliably adhered to the outer circumferential surface of the trim body 2 coated with the adhesive B, and the decorative cloth 3 can be more neatly attached to the outer circumferential surface of the trim body 2. Can be pasted.

In addition, in the upholstery device 12 of the embodiment, the pressing is performed by the device 90.
, the horizontal roller 92, the vertical roller 94, and the terminal roller 95 are shown arranged in this order along the conveyance direction of the trim body 2, but it is also possible to rotate the trim body 2 in the cross-sectional circumferential direction to correspond to each part. By arranging the rollers 92, 94, and 95, the arrangement order of the rollers 92, 94, and 95 can be arbitrarily changed.

After that, in the finishing step (■), the caulking machine 14
The cross section is bent into the final product shape as shown in Figure 2,
Thereafter, the fabric trim 1 of a predetermined length is manufactured by cutting with a cutting machine 15.

The fabric trim 1 manufactured in this way is
The decorative fabric 3 is attached to the trim body 2 which has already been bent into a substantially inverted U-shaped cross section through the bending process (■).
Compared to the conventional manufacturing method in which the decorative fabric is pasted and then bent, the decorative fabric 3 of the upholstered trim 1 does not stretch, and the density of the nap of the upholstered fabric 3 changes less.
Can prevent deterioration of appearance. Furthermore, even if the manufactured fabric trim 1 is bent and attached to a predetermined location, the decorative fabric 3 does not stretch much in advance, so tearing of the decorative fabric 3 can be prevented.

In the example, in the finishing step (2) after passing through the upholstery step V, the upholstery trim 1 is bent by the caulking machine 14 for fine adjustment, but since the amount of bending is small, the decorative fabric 3 The effect of elongation is smaller than that of conventional manufacturing methods, and does not reduce the effects of the present invention. If the bending process can be performed into the final product shape, the caulking machine 14 in the finishing step (2) becomes unnecessary.

Further, in the embodiment, the method for manufacturing the rubber upholstered trim 1 has been explained, but of course the present invention can also be applied to the manufacturing of the synthetic resin upholstered trim, and in that case, vulcanization Process ■ becomes unnecessary.

Further, in the embodiment, a method for manufacturing the upholstered trim 1 provided with the sponge portion 2c has been described, but of course, the upholstered trim 1 not provided with the sponge portion 1 as shown in FIG.
The present invention can also be applied to the case of manufacturing 21.
