Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for manufacturing a desired product such as an automobile door trim, a quarter trim (a trim for covering a panel portion on which a side door on a side of a seat is not provided), or an instrument panel. The present invention relates to a sheet material setting device used for performing sheet material setting work.

[0002]

2. Description of the Related Art As is well known, a door trim of an automobile, for example, often has a structure in which a sheet material made of cloth or the like is attached to a surface of a base member made of a synthetic resin which is a main body of the door trim. With such a configuration, the surface of the base member can be decorated with the skin material, and the grade of the entire door trim can be enhanced.

Conventionally, means for sticking a sheet material to a base member of a door trim is disclosed, for example, in JP-A-2-3056.
There is a means described in Japanese Patent Application Publication No. 26 (1994). According to the means described in the publication, as shown in FIG. 7 of the present application, first, an outer peripheral edge of the sheet material 2e is clamped and supported by a hollow frame-shaped sheet material supporting member 6e, and a door trim is provided above the sheet material 2e. The base member 1e is supported by the upper mold 93 and arranged. Next, the lower die 94 disposed below the sheet material supporting member 6e is raised, whereby the sheet material 2e is pressed upward by the lower die 94.
According to such a means, the sheet material 2 is
e can be pressed against the surface of the base member 1e, and the work of sticking the sheet material 2e can be performed.

[0004]

However, conventionally, there are the following problems to be solved.

[0005] That is, when the sheet material 2e is stuck, the sheet material 2e supported by the sheet material supporting member 6e is brought as close as possible to the surface of the base member 1e, and then the base member 1e is lowered into a lower mold. Pressing with 94 is desirable. Sheet material 2e is base member 1e
If it is pushed upward in a state far away from the surface of
The sheet material 2e separates from the sheet material supporting member 6e at an early stage before the sheet material 2e contacts the surface of the base member 1e, and the tension is lost, and wrinkles are formed on the sheet material 2e. This is because a problem such as a large number of occurrences occurs. Therefore, in order to eliminate such inconvenience, it is necessary to reduce the dimension Lb of the gap between the sheet material supporting member 6e and the upper die 93 as much as possible.

However, in the related art, if the dimension Lb is reduced, it is very difficult and inconvenient to clamp the sheet material 2e on the sheet material supporting member 6e disposed below the upper die 93. Further, by temporarily providing the sheet material supporting member 6e so as to be movable in the left-right horizontal direction, the sheet material supporting member 6e is moved to a position retracted from below the upper mold 93, and then the sheet material 2e is clamped. However, the sheet material supporting member 6e is
In order to move and arrange below 3, a certain gap needs to be provided. Therefore, conventionally, there was a certain limit in reducing the dimension Lb of the gap. As a result, conventionally, when the sheet material 2e is pressed against the surface of the base member 1e, the sheet material 2e cannot be brought sufficiently close to the surface of the base member 1e in advance, and the sheet material 2e is stuck. Was not able to be done in good looks.

Further, in the conventional means, the base member 1e is set on the downward surface of the upper die 93. Therefore, when the operator sets the base member 1e on the upper die 93, the operator has to move the upper member 93 upward. It is necessary to set the base member 1e so as not to fall under the mold 93 or to insert a hand below the upper mold 93 before dropping the base member 1e on its downward surface. Therefore, the setting work of the base member has conventionally been troublesome. In particular, the work of setting the base member 1e on the upper mold 93 needs to be newly performed each time the work of sticking one sheet material 2e is completed, and the number of times of the work is extremely large. Had become. Furthermore, the upper mold 93
Needs to be manufactured in a structure in which the base member 1e does not drop below, and the cost is high.

The present invention has been conceived in view of such circumstances, and can easily perform a setting operation of a sheet material and an object to which the sheet material is stuck. It is an object of the present invention to provide a sheet material sticking device capable of performing a work of sticking a sheet material well.

[0009]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

That is, the present invention provides a sheet material supporting member for clamping an outer peripheral edge of a flexible sheet material to support the sheet material, and a sheet material supported by the sheet material supporting member. A sheet material sticking device comprising: a press die that can be raised and lowered so as to be able to press downward from above, wherein a supporting means for supporting the sheet material support member so as to be able to move up and down, and raising the sheet material support member And a lifting / lowering operation interlocked with the pressing die so that when the pressing die is lowered, the sheet material supporting member is pressed and lowered against the pressing force of the pressing means. And a pressing member.

In the sheet material sticking apparatus according to the present invention, the pressing die is disposed above the sheet material supporting member in a state where an object to be stuck, in which the sheet material is stuck below the sheet material supporting member, is set. Is lowered, and the sheet material supported by the sheet material supporting member is pressed downward using a pressing die, whereby the sheet material can be stuck on the surface of the object to be stuck.
In the present invention, the following specific effects can be obtained.

That is, according to the present invention, the sheet material supporting member can be raised to a predetermined height by the urging force of the urging means in a normal state when the sheet material is not stuck. Therefore, it is possible to secure a relatively large space below the sheet material supporting member, and it is possible to appropriately perform an operation of arranging the object to be stuck below the sheet material supporting member. Also, since the object to be stuck may be set so that the surface thereof faces upward, unlike the case where the object to be stuck is set so as not to drop on the downward surface of the conventional upper die, the The setting operation becomes significantly easier. Further, below the sheet material supporting member, an appropriate mounting table for temporarily mounting the sheet material is arranged, and a flexible sheet material is mounted on the mounting table. After that, it is possible to perform an operation of clamping the outer peripheral edge to the sheet material supporting member. Of course, at this time, by raising the press die above the sheet material, it is possible to appropriately prevent the press die from interfering with the sheet material setting operation. Therefore, according to the present invention, the setting operation of the sheet material and the object on which the sheet material is to be stuck can be performed very easily, and the workability can be improved.

As a further important effect, in the present invention,
When the pressing die is lowered, the sheet material supporting member can be pressed and lowered against the urging force of the urging means. Therefore, when the sheet material is pressed downward by the pressing die, the sheet material is stuck beforehand. It can be close to the surface of the member. Therefore, the sheet material can be appropriately pressed against the surface of the object to be stuck without causing a situation in which the outer peripheral edge of the sheet material detaches from the sheet material support member early and loses its tension. As a result, in the present invention, the sheet material can be stuck in a good appearance.

Further, according to the present invention, since the pressing member for pressing and lowering the sheet material supporting member is capable of moving up and down in conjunction with the pressing die, the sheet material supporting member can be moved when the sheet material is stuck. The advantage that the pressing member can be lowered at an appropriate timing and reliably can be obtained. In addition, since it is not necessary to separately provide a dedicated driving unit for lowering the pressing member, it is possible to minimize the complexity of the entire apparatus.

As described above, according to the present invention, the work space for setting the sheet material and the object to be stuck is secured by raising the sheet material supporting means in the normal state, while the sheet material is stuck. Conventionally, when the work is actually performed, the sheet material supporting means is pressed down by a pressing member which can be interlocked with the pressing die to perform a good-looking work in a state in which the sheet material is brought close to the object to be worked. Are based on a new technical idea that cannot be seen, and exhibit the various special effects described above.

In a preferred embodiment of the present invention, the pressing dies include a first pressing die and a second pressing die which can move up and down relative to the first pressing die. When the sheet material is pressed downward by the first pressing die and the second pressing die, the second pressing die presses a part of the sheet material downward prior to the first pressing die. It can be configured.

According to such a configuration, for example, in the case where a relatively large convex portion or concave portion exists on the surface of the object to which the sheet material is to be pasted, the vicinity of the convex portion or the concave portion may be determined. If a part of the sheet material is pressed in advance of the other part using the second pressing die, the part of the sheet material can be pressed smoothly against the surface of the object to be stuck, and the entire sheet material can be pressed. Thus, the sheet material can be stuck in a better appearance so that many wrinkles do not occur.

The features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention.

[0019]

The air damper 5 corresponds to an example of the urging means according to the present invention. The reciprocally movable rod 5a is connected to the plurality of support rods 40 via a substantially horizontal connecting rod 50. Have been. The rod 5a of the air damper 5 always exerts a biasing force F upward. Therefore, the plurality of support rods 40 and the sheet material support table 6 are also constantly receiving the urging force F.

As best shown in FIG. 2, the two pressing dies 30 and 31 are for pressing the sheet material 2 against the surface of the base member 1. The first pressing die 30
This is for pressing a large area of the sheet material 2 against the surface of the base member 1, and the downward surface thereof is
Is formed in an uneven shape substantially corresponding to the uneven shape of the surface of. On the other hand, the second pressing die 31 is for pressing a predetermined area of the sheet material 2 partially, and its size is considerably smaller than that of the first pressing die 30. The second pressing die 31 is slidably fitted into a hole 30 a formed in the first pressing die 30.

The elevating mechanism 3 comprises a first elevating body 3
2, a second elevating body 34, and a plurality of reciprocating cylinders described below. That is, the first lifting body 32
The rod 84a of the first reciprocating cylinder 84 supported on the ceiling portion of the fixed frame 99 and the elevating guide rod 85,
The first reciprocating cylinder 84 can be moved up and down by driving the first reciprocating cylinder 84. The second elevating body 34 is connected to the lower part of the first elevating body 32 via a plurality of second reciprocating cylinders 86, and can be moved up and down by driving the plurality of second reciprocating cylinders 86. The first pressing die 30 is attached to the second elevating body 34. Therefore, the first pressing die 30
The so-called two-stage lifting operation can be performed by driving the first reciprocating cylinder 84 and the second reciprocating cylinder 86. On the other hand, the second press die 31 is supported by the second elevating body 34 via a third reciprocating cylinder 87. Therefore, the second pressing die 31
By driving the reciprocating cylinder 87, a so-called three-stage elevating operation in which the elevating operation is further performed is possible.

The pressing rods 33 are attached to the first operating body 32 so as to project downward.
The front end of the lower end faces the upper surface of the sheet material support table 6. As a result, when the first operating body 32 is lowered, as shown in FIG. 3, these pressing rods 33, 33 are also lowered and abut on the upper surface of the sheet material supporting table 6, so that this sheet material supporting The table 6 is pressed and lowered against the urging force of the air damper 5.

As best shown in FIG. 2, the cutting device 7 includes one or a plurality of blades 70 formed in a shape surrounding the entire outer peripheral side surface of the first pressing die 30, A fourth reciprocating cylinder 88 for moving the body 70 up and down relative to the first pressing die 30 is provided. The blade body 70 is formed in such a shape and size that the sheet material 2 attached to the surface of the base member 1 can be cut at a position slightly outside the groove 10 for cutting wood. Further, the blade body 70 is a heating blade that can smoothly cut the sheet material 2 even if the sheet material 2 is made of cloth. As means for using the blade body 70 as a heating blade, the blade body 70
Instead of the means for separately attaching an electric heater, a means for directly supplying a current to the metal blade body 70 and causing the blade body 70 itself to generate heat may be used. By adopting such means, unlike the case where an electric heater is separately provided, it is possible to prevent a temperature gradient from being generated at various points of the blade body 70, and it is possible to efficiently increase the temperature of the blade edge portion.

The movable table 91 is shown in FIGS.
As shown in FIG. 1, a jig 90 for supporting the base member 1 is configured to be tiltable at an appropriate angle. FIG.
, The movable table 91 is mounted on a slider 96 that can move on a rail 95. The rail 95 extends from below the sheet support table 6 to the side thereof. For this reason, the movable table 91 can be arranged either below the sheet material support table 6 or on its side.

Next, an operation of attaching the sheet material 2 to the base member 1 using the attaching device A will be described.

First, as shown in FIG. 1, when the base member 1 is set on a jig 90 disposed on the side of the sheet material support table 6, the movable table 9
1 is moved toward the sheet material support table 6. At this time, the sheet material supporting table 6 is raised by the urging force F of the air damper 5, and a relatively large space can be secured below the sheet supporting table 6. Therefore, as shown in FIG. 2, the base member 1 can be appropriately arranged below the sheet material support table 6 from the side thereof.

If the sheet material supporting table 6 is raised, a large space H can be formed between the sheet material supporting table 6 and the base member 1. Therefore, when the sheet material 2 is set on the sheet material support table 6, the receiving plate 89 for receiving the sheet material 2 can be arranged in the space H. That is, the work of setting the sheet material 2 on the sheet material support table 6 is performed, for example, manually.
Since the sheet material supporting table 6 has a hollow frame shape and the sheet material 2 is made of a flexible soft cloth, the sheet material 2 is directly placed on the sheet material supporting table 6 and the outer peripheral edge of the sheet material 2 is formed. It is difficult to perform clamping work. On the other hand, the receiving plate 8 is located below the sheet material support table 6.
When the sheet material 9 is disposed, the sheet material 2 can be placed on the receiving plate 89 until the work of clamping the sheet material 2 to the sheet material supporting table 6 is completed. Work is facilitated. In order to set the sheet material 2, it is necessary to secure a certain space above the sheet material support table 6. You just have to wait quite high.

Next, after the setting of the sheet material 2 is completed, the first reciprocating cylinder 84 is driven to lower the two press dies 30, 31. In this case, the pressing rods 33 are also lowered at the same time, and the sheet material supporting table 6 is pressed and lowered by these pressing rods 33, 33. Thus, as shown in FIGS. 3 and 4, the sheet material 2 can be made to approach the surface of the base member 1 while being supported by the sheet material support table 6. When the sheet material support table 6 is lowered by an appropriate dimension La and approaches so that the sheet material 2 does not contact the base member 1, the first reciprocating cylinder 84 at that time.
Of the sheet material supporting table 6 is stopped.
Not to fall.

Thereafter, the second reciprocating cylinders 86, 86 are operated to lower the press dies 30, 31, and the press dies 30, 31 press the sheet material 2 downward. However, in this case, the second pressing die 31 is set in advance so as to protrude below the first pressing die 30 by the operation of the third reciprocating cylinder 87, and the second pressing die 31 is moved to the second It precedes the one press die 30. Then, as the first pressing die 30 descends, the second pressing die 31 is relatively raised with respect to the first pressing die 30, and finally, as shown in FIG. , Both the pressing dies 30 and 31 press the sheet material 2 against the surface of the base member 1.
For example, as shown in the figure, when a relatively large convex portion 12 serving as an armrest portion is present on the surface of the base member 1, a large wrinkle or the like on the sheet material 2 at a side portion of the convex portion 12. Is likely to occur, but the second pressing die 3
If the part is pressed first by using 1, the sheet material 2 can be prevented from generating large wrinkles or the like in the part.

The movable table 91 is inclined as necessary, and is set at an angle at which the second pressing die 31 can easily press the sheet material 2 against the base member 1. When the sheet material 2 is pressed downward by the pressing dies 30, 31, the outer peripheral edge of the sheet material 2 is
, The sheet material 2 is given a tension. Further, since the clamper 61 can be retracted by the cylinder 63, it is possible to more reliably apply tension to the sheet material 2 by this operation. Therefore, it becomes possible to press the sheet material 2 against the surface of the base member 1 with less wrinkles. When the sheet material 2 is pressed against the surface of the base member 1, the sheet material 2 is applied to the base member 1 via an adhesive previously bonded to the base member 1.
Glued to the surface.

After the sheet material 2 is attached,
As shown in FIG. 6, the blade member 70 of the cutting device 7 is advanced downward to cut the sheet material 2 at a position closer to the outside of the concave groove 10 of the base member 1. In this case, in order to prevent the surface of the base member 1 from being damaged by the blade body 70 which is a hot blade, the sheet material 2 is provided below the portion to be cut of the sheet material 2.
Underlay members such as brass plate members (not shown)
Is provided in advance. Even when the sheet material 2 is cut, a constant tension can be applied to the sheet material 2 by the clamper 61, and the sheet material 2 can be appropriately cut. According to such a cutting operation, a sheet material having a similar shape slightly larger than the contour of the groove 10 can be obtained from the sheet material 2 having a rectangular shape. The end portion of the periphery can be grained into the concave groove 90 of the base member 1.

When the cutting operation of the sheet material 2 is completed,
What is necessary is just to raise the cutting device 7 and the pressing dies 30, 31 to the original positions. If the first operating body 32 is raised to return the press dies 30 and 31 to the up position, the pressing rods 33 and 3 are raised.
3 also rises with this. Then, the sheet material support table 6 rises again by the urging force of the air damper 5, and
A relatively large gap is formed between the base member 1 and the base member 1. Accordingly, the work of moving the movable table 91 to the side from below the sheet material support table 6 can be appropriately performed, and the work of taking out the base member after the sheet material has been stuck can be smoothly performed.

In the above embodiment, the first pressing die 3
0 is raised and lowered in two stages using a plurality of reciprocating cylinders 84 and 88, and the second pressing die 31 is
4, 88, 87 are used to raise and lower in three stages, but the present invention is not limited to this. In the present invention, it is needless to say that a pressing die composed of a single member having neither the first pressing die nor the second pressing die may be used as the pressing die. The vertical movement may be performed by a cylinder or one reciprocating drive means instead of the cylinder. That is, for example, a damper such as an air damper or an oil damper having an extendable rod is used as a pressing member for pressing and lowering the sheet material supporting table 6, and the damper moves up and down together with the pressing die. In such a case, the sheet material supporting table can be downwardly pressed by the damper at the initial stage of the lowering of the pressing die, and thereafter, after the sheet material supporting table has been lowered by an appropriate dimension, the lower surface portion of the sheet material supporting table By using a stopper or the like that mechanically abuts on the sheet material to prevent the sheet material supporting table from lowering further, it is possible to lower only the pressing die while contracting the rod of the damper. .

Further, in the above embodiment, the case of manufacturing the door trim has been described as an example, but the present invention is not limited to this. The setting device according to the present invention is:
The present invention can be applied to various sheet material application other than the application of the sheet material to the base member constituting the door trim. Of course, it is not necessary to provide a cutting device for cutting the sheet material.

In addition, the specific structure of each part of the sheet sticking apparatus according to the present invention can be variously changed in design. For example, instead of the air damper, another kind of damper or a spring may be used as the urging means for exerting the urging force to raise the sheet material supporting member.
