Abstract

PURPOSE:To stick accurately a thin film to a molded body and insert automatically a fringe part of the thin film in to a groove, by a method wherein the title device is made into constitution where a top force into which an annular groove is formed, a bottom inner and outer forces held elastically and an insertion blade are combined with one another. CONSTITUTION:A thin film S cut into a desired form, to the rear of which an adhesive agent is applied, is inserted into a spatial part surrounded by a plurality of guide plates 10A by turning the surface of the same downward and put the same on a fixed position of a bottom inner force 6. Then a molded body W where a groove U is formed in the fringe part to which the thin film S is to be stuck is put on the upper part of a bottom outer force 10 by turning the groove U to the lower part and causing the same to correspond to an insertion blade 9 which is in a gap between the bottom inner and outer forces 6, 10. Then a top force fitting plate 1 is lowered and the molded body W is stuck to the undersurface of a top force 2. When the lowering is kept on further, the bottom outer and inner forces 10, 6 are lowered against coil springs 12, 7 at the same time and an end part of the circumference of the thin film is inserted into the groove U of the molded body W with the insertion blade 9 and the lowering is stopped. Then at a point of time when lamination between the molded body W and thin film becomes sufficient, a press machine performs reverse action.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is directed to attaching a thin film made of cloth or the like to a grooved molded body, such as an automobile door trim, and attaching the peripheral edge of the thin film to the groove of the molded body. This invention relates to a thin film pasting device that can be inserted into a computer.

(Prior art and problems) In recent years, thin film materials such as cloth or plastic sheets are pasted onto molded parts to partially create interior parts for automobiles, decorative building materials, exterior parts of household electrical appliances, etc. There are many ways to make the exterior look luxurious by using different materials, colors, and patterns.

In addition, various efforts have been made to improve the appearance of the peripheral edge of the thin film material, and the most attractive structure is to create a groove in the part of the molded product where the peripheral edge of the thin film is located. A groove is provided, and the peripheral edge of the thin film is inserted into this groove.

By adopting this structure, the peripheral edge of the thin film is hidden in the groove, and the connection area between the precept form and the thin film is finished with an extremely clean line, resulting in an even better appearance.

However, in order to realize such a structure, there was no suitable equipment and the peripheral end of the thin film had to be inserted into the groove of the precept by hand, which was a cumbersome process.

(Objective) The present invention was developed in view of the above-mentioned problems, and it is an object of the present invention to provide a device that can attach a thin film to a molded body and automatically insert the peripheral edge of the thin film into the groove of the molded body. This is the purpose.

(Example) Embodiments of the present invention will be described in detail below based on the drawings.

First, the configuration will be explained with reference to FIG. 1. The molded body (W) has an annular groove (U) formed on the lower surface of the upper die mounting plate (1) which is attached to a press machine (not shown) and is movable up and down. The upper mold (2) has a mold surface that is almost the same as the back shape of
) is installed.

Below the upper die mounting plate (1), there is a support frame (5) (not shown) with a fixing plate (4) having the same outer peripheral shape.
5), and is fixedly supported at a corresponding position inside the groove formed in the upper mold (2).

A lower inner mold (6) having a mold surface corresponding to the inner shape of the groove forming part of the upper mold (2) is mounted on the upper part of the fixing plate (4) via a plurality of coil springs (7) (7). Elastically supported. The lower inner mold (6) is prevented from swinging in the lateral direction by a guide pin (8) that is attached to the lower surface of the lower inner mold (6) and passes through the fixing plate (4) so that it can move up and down. It is designed to go up and down.

Further, an insertion blade (9) corresponding to the uneven shape of the groove formed in the upper mold (2) is erected on the peripheral edge of the fixed plate (4). The insertion blade (9) is normally located slightly below the surface of the lower inner mold (6). Further, on the outside of the lower inner mold (6), a perforated lower outer mold (10) having a mold surface that is almost the same as the outer mold surface of the groove formed in the upper mold (2) is provided on a movable plate. (1 1
) and a plurality of coil springs (1 2) (1 2) are elastically supported on the lower mold mounting plate (3) with a slight gap between the lower inner mold (6) and the lower outer mold. (l
O) is normally supported so as to protrude slightly above the surface of the lower inner mold (6).

In addition, a plurality of L-shaped guide plates (10A) are attached to the inner peripheral edge of the upper end of the lower outer mold (10) through bolts (10C) in the holes (10B) so that their positions can be adjusted in the horizontal direction. ing. Note that the lower outer mold (10), like the lower inner mold (6), is moved up and down guided by guide pins (13) so as to prevent it from swinging in the lateral direction.

Furthermore, in the figure (1 4) (1 4) are guide pins provided on the lower die mounting plate (3), (1 5) (
1 5) is a guide tube attached to the upper mold mounting plate (1), and when both are fitted, the upper mold (2) and the lower mold (6) are connected.
) (10). (S) is a thinner film than cloth.

The structure constructed in this way is in the state shown in Figure 1.
A thin film (S) that has been cut into a desired shape and coated with adhesive on the back is inserted with the surface facing downward into a space surrounded by a plurality of guide plates (10A) to form a lower inner mold (6). Place it in place. At this time, the thin film (S) is guided by the guide plate (10A) and positioned accurately.

Next, grooves (
A precept shape body (W) shaped like U) is placed on the upper part of the lower outer mold (10) with the groove (U) facing downward, and the lower inner mold (6) and the lower outer mold (10
) and place it in correspondence with the insert blade (9) in the gap between the two. At this time, an adhesive is applied to the portion to which the thin film (S) is attached and the groove (U) portion, if necessary.

Next, a press machine (not shown) is operated to lower the upper die mounting plate (1). By this lowering operation, the upper mold (2) first pinches the precept-shaped object (W) with the lower outer mold (lO), bringing the precept-shaped object (W) into close contact with the lower surface of the upper mold (2).

If the lowering continues in this state, the lower outer mold (10) will be lowered against the coil springs (1 2) (1 2), and the thin film (S) will be brought into close contact with the lower surface of the compact (W) and the soil will be removed. Type (
2) and the lower molds (6) and (10), the precept-shaped body (W) and the thin film (S) are sandwiched. As the lower outer mold (10) and lower inner mold (6) continue to descend in this state, they simultaneously descend against the coil springs (1 2) (1 2) (7) (7), and the thin film The peripheral edge of (S) is the insertion blade (9
) is inserted into the groove (U) of the molded body (W) as shown in FIG. 2 (A), and its descent is stopped.

This state continues for a predetermined period of time, and when the molded body (W) and the thin film are sufficiently bonded, a press machine (not shown) operates in reverse. Due to this operation, the thin film (S) is stuck to the molded body (W), and the peripheral end of the thin film (S) is inserted into the groove (U) (see Figure 2 (B)). The lower outer mold (lO
) is placed on top. (Fig. 1) This is removed manually and the same operation as described above is repeated.

(Effects) As is clear from the above description, the present invention has a structure in which an upper mold having an annular groove, a lower inner mold and a lower outer mold that are elastically supported, and an insertion blade are skillfully combined. , the thin film can be accurately attached to the molded body, and the peripheral edge of the thin film can be automatically inserted into the groove of the molded body, which is a great advantage.
