Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to decorative emblems, plaques, and similar products (hereinafter collectively referred to as "decoration bodies") having a crosslinked plastic layer on the decorative surface. The present invention relates to a manufacturing method, and particularly to a method for punching out a plurality of decorative bodies having a plastic coating without damaging the plastic coating or deforming the decorative bodies during die cutting.

(Prior Art) In U.S. Patent Application No. 54,548 filed on July 5, 1979, the present applicant has applied a series of decorative designs in the form of an emblem or plaque and provided an adhesive layer on the back side. Flow coating a foil-like substrate with a polyurethane composition that is crosslinked by radiation.
A method for mass production of decorations having a smooth coating is disclosed.

In this method, for example, a cutting die shown in FIG. 3 is used, and individual decorative bodies are punched out from the base by pressing the decorative body with a male die into a female die in accordance with the decorative design. However, this method tends to make decorative emblems etc. dome-shaped. Although this dome shape has aesthetic value in some cases, it is difficult to control the depth of the dome shape, it is difficult to adapt the decoration to a flat surface, and it is difficult to Generally speaking, it has the disadvantage that it is difficult to adapt to a surface with a curvature different from that of a dome shape. Furthermore, if the decorative body is shaped like a dome when the decorative body is die-cut, sharp cutting edges cannot be obtained, and the decorative body may sometimes peel, catch, or chip, or the edges may become deformed and the base body may be damaged. The foil may oxidize and turn silvery white. Additionally, the adhesive tends to ooze out from the base and contaminate the mold when it is cut out.

All of these drawbacks reduce the weather resistance of the die cut decoration.

A typical decoration produced in accordance with the present invention and the aforementioned U.S. patent application consists of a sheet of aluminum coated with a decorative insignia or graphic painted or silkscreened on one side and coated with a cross-linked polyurethane on the other side with an adhesive composition. Obtained by punching out a laminate with objects attached.

The adhesive layer is coated with release paper. An example of the laminate is shown in FIG.

(Problem to be Solved by the Invention) When this laminated structure is punched out with a mold, the plastic-coated substrate is removed from the mold because the polyurethane and adhesive composition are relatively soft compared to the aluminum sheet. It moves slightly as it is pulled by the cutting blade.

This causes the base body to flex below the male surface. This deflection causes the disadvantages mentioned above, in particular it gives the decoration an irreversible dome shape, imparts unfavorable properties to the edges of the decoration, causes peeling and impairs weather resistance.

This method of cutting out the decorative body does not cause the decorative body to form a dome or peel off, and as a result, the plastic coating has sharply cut edges and has good weather resistance and durability. There is a need for a method for cutting out decorative objects that have a body.

SUMMARY OF THE INVENTION The present invention provides a method for obtaining substantially flat decorative emblems, plaques and the like with sharp edges. According to the invention, the individual decorations are -L of the base.
A series of decorative designs are applied to the laminate, which is then stamped out of the laminate with a layer of cross-linked plastic on top.

In the die-cutting press device used in this invention, a pressure support is elastically attached within the female mold, and by sandwiching the decoration between the male mold and the pressure support, the base of the decoration can be removed from the male mold. This is to prevent the mold from sagging downward.

In accordance with the invention, when the die-cutting press is lowered onto the substrate, the pressure support supports the substrate with sufficient pressure against the male die to prevent the substrate from sagging against the male die surface. When the press is fully closed, the male mold depresses the pressure support and forces the substrate into the female mold. The pressure support is mounted with appropriate elasticity and has sufficient resistance to prevent the substrate from deflecting and to prevent the plastic sheath from being damaged or deformed.

Once the die-cutting operation has completed one cycle, the press opens to free the substrate. Owing to the resilient attachment of the pressure support, the pressure support returns to its original position, so that the decoration which has been pulled out of the basic body can be reinserted into the basic body and transported to the ejection device.

There, the decoration is extruded from the base and collected.

In one embodiment of the invention, two sets of workstations (
A die-cutting device with a working 5tation is used, in which the decoration is cut from the substrate and reinserted into it at one workstation, and at the same time the decoration is ejected and collected from the substrate at the other workstation. A preferred embodiment is that both the die-cutting decoration and the protruding base body are supported on a resiliently mounted table-L during the operation.

In another embodiment of the invention, the mouth of the female mold is provided with a steel ruler-like blade. The blade minimizes punching force and potential for delamination, reduces burrs from punching aluminum, and creates sharp longitudinal edges. Furthermore, the adhesive layer and release paper can also be cut cleanly.

Objects and advantages of the tub of the present invention will become apparent from the following description, the accompanying drawings, and the claims.

Figures 5a and 5b are schematic cross-sectional views of a punching die press device and a sectional view for explaining how to use the same; FIGS. FIG.

The present invention relates to a method of forming a decorative body, the cross section of which is shown in FIG. A typical decorative body has an adhesive layer 12
It consists of a base body 10 with a material attached to its back surface. In order to prevent the adhesive layer from accidentally adhering to the surface of other objects, or from getting flakes or lint on the decorative body, and to facilitate handling, a release paper 14 is attached to the adhesive as shown in the figure. layer 1
2 are laminated.

A primer layer or an undercoat layer 16 is provided on the upper surface or design surface 13 side of the substrate 10, and a decorative design or insignia 18 is applied to the second layer by painting or silk screen printing.
is being carried out. This design is coated with a transparent plastic layer 20, which gives it an aesthetic appearance and makes the article durable and weather resistant. plastic covering 2
0 is optionally further covered with a protective film 22 such as a polyethylene film.

The construction for producing these ornaments is shown in FIG. There is a design 24 on the drawing surface 25 of the base 26.
are arranged in a formation. The design part represents a laminated structure as shown in FIG. 1, but the plastic coating 28 is shown separately for simplicity. The laminated base is 2
6, it should be understood that it has a laminated structure as shown in FIG.

The local portions of the substrate may be covered with plastic over the entire substrate or only individual design portions 24 may be covered. To cover only the design area and not cover the adjacent areas, the design may be provided with a dyke or other peripheral edge to stop the flow of plastic at the edge of the design. However, it is easier to design-L
The process is to completely cover the design by placing a certain amount of plastic on it. If the area is small, it will be covered immediately as shown in FIG.

A systematic description of each layer to make the above laminate, as well as the coating techniques used to process it, are disclosed in detail in the aforementioned US patent application Ser. No. 54,548.

The substrate coated with liquid plastic may be plastic or metal foil. Preferably O,075mm
(0,003 inch) to 0.5 mm (0,020 inch) thick aluminum foil.

The foil-like substrate is decorated by adding an appropriate design or several types of designs. A series of designs, usually in the form of emblems or plaques on the sides, are applied to the foil. In order to add a series of designs to the metal foil, it is preferable to use silk screen printing or lithographic printing. By doing so, the design can be emphasized by the unevenness added to the intended part. However, it goes without saying that other means can be used to add the decorative design. The foil or emblem may be embossed to give a three-dimensional effect.

It is preferable to treat the −L side of the substrate with a primer before printing. Any suitable primer can be used, for example a silane-based primer.

The primed and decorated substrate is then placed on a vacuum mat held on a horizontal table with vacuum suction available. The technology is US 4 yen permit No. 4,03
No. 4,708. A vacuum suction is then applied through the mat to the underside of the foil to hold the substrate flat and horizontal. The flow characteristics of the liquid plastic and the wetting characteristics of the substrate are used to control the spread of the plastic. As a result, the liquid plastic is coated with a uniform thickness on a predetermined portion of the foil and adjacent portions thereof.

Control of plastic flow can also be achieved by using sharply defined edges around the substrate periphery or by using defined sections of the substrate as disclosed in U.S. Pat. No. 54,548.

Flow coating is a pathwise deposit coating.
ion). That is, a number of orifices (or nozzles) coat the primed and decorated foil while moving at a constant speed while it is held stationary. The number of orifices used will vary depending on the width of what is being laid. The required thickness is approximately 0.5mm
(0,02 inches) to 10゜mm (0,04 inches)
It is between.

The plastic is preferably a liquid polyurethane consisting of two components (polyol and isocyanate), which are mixed immediately before coating and crosslinked by heating. This type of polyurethane is disclosed in U.S. Patent No. 4,100,01
It is disclosed in No. 0.

Basically, the mixture consists of a polyether polyol component (component A) such as a trifunctional, trifunctional and/or tetrafunctional polypropylene glycol containing a suitable catalyst and a diisocyanate component (component B) such as an aliphatic diisocyanate. It consists of For example, lead or mercury compounds are used as catalysts. It retards crosslinking at room temperature and
It functions to adjust the time so that the liquid polyurethane is completely spread before it hardens. Examples of diisocyanates include those manufactured by DuPont de Nemoursan, as described in U.S. Pat. No. 4,100,010, which is specifically incorporated herein by reference.
``Hylena W'' by d Co,)
Polyether polyols include compositions such as P-410 and TP-440 sold as PIuracol J (registered trademark) by BASF Wyandotte. It may also be a combination of polyether and polyester polyol, and the use of polyester polyol makes the polyurethane more flexible after crosslinking. The ratio of component A to component B is preferably between 50 and 60:40 and 50.

Polyester polyols or polylactone polyols may be used in place of polyether polyols.

When formulating certain plastic compositions from among the compounds disclosed in the aforementioned US patents, it is important to use catalysts that slow down the crosslinking time to some extent. The reason for this is that when the liquid plastic is coated, it is sufficiently cast to the sharply defined periphery before the crosslinking is completed. Otherwise, a uniform thickness and smooth coating may not be obtained.

Thus, polyurethanes may be formulated from among the compounds described in the aforementioned US patents which disclose providing more flexible crosslinked plastics. As long as the adhesion to the substrate remains strong, a somewhat flexible plastic covering is preferable, so that the emblem,
Decals, etc. will be easier to attach. For example, even if the decorative panel for an automobile according to the present invention is attached to a curved surface, it can be adapted to the curved surface.

Most types of plastics available can be crosslinked by irradiation with infrared or ultraviolet light. Since the polyurethane composition series is capable of thermal crosslinking, infrared lamps may be used, or other heat sources may be used. Note that it is desirable to heat the plastic-coated foil from both sides to complete the crosslinking.

The vacuum suctionable table device described in US Pat. No. 4,034,708 is a preferred device because it has heating and cooling capabilities and makes this possible. However, it is preferable to use an infrared lamp as the heat source for heating both the upper and lower surfaces. This can also be accomplished by using an infrared absorbing mat as the vacuum mat. That is, the mat receives heat from the irradiated infrared rays and transfers the heat from its lower surface to the plastic-covered foil.

After crosslinking, the plastic coated substrate is cooled and removed from the table, after which the respective emblem or plaque is stamped with a cutting die into the shape of the particular emblem or plaque.

It has been found that by preventing the plastic-coated substrate from sagging during die-cutting of the decorative body, it is possible to obtain an article that is substantially flat and has sharp, right-angled edges. However, this is not the case for articles that have a decorative pattern with concavities and convexities in advance. and,
This has made it possible to provide a decorative body that does not peel off and has good weather resistance and durability.

According to the invention, the decorative body is cut and punched from a plastic-coated laminate base using a mold press shown in FIG. 4 or 5.

The mold press shown in FIGS. 4 and 5 has two sets of workstations, and the plastic coated substrates are moved from right to left in the figures.

It will be appreciated that the use of separate die presses for the die cutting operations and for the ejection operations described below is equivalent to the illustrated die press having two sets of workstations. It will also be clear that the ejection operation may also be carried out by hand, without the use of a die pressing device.

For purposes of background, a conventional die press apparatus is shown in FIG. 3a. This die pressing device has a male die holder 40 which is connected to a lower die holder 42 which cooperates with it to perform die cutting. The male mold holder 40 is connected to a press drive (not shown) by a shaft 43, and the lower mold holder 42 is secured to the press base at its ears 45 by clamps or other means. The male mold holder 40 and the lower mold holder 42 are aligned by a plurality of guide shafts and guide tubes (both not shown).

This press device is usually mechanically operated, but a hydraulic press may also be used.

The male die 46 is attached to the male die holder 40 with a stripper plate 44 surrounding it. The stripper plate 44 is assembled closely around the male die 46 and includes a shoulder bolt or stopper bolt 48,50 and a spring 49.
．． It is attached to a spring device consisting of 51 and is able to reciprocate elastically. Only two sets of spring devices are shown in FIGS. 3a and 3b; the other spring devices are omitted from this schematic cross-sectional view because they are located behind them.

The protrusion of the shoulder pad 48.50 and the stripper plate 44 are screwed together. This stripper plate 44 is used to hold the substrate in a predetermined position during die cutting and to prevent the cut edge from sticking to the male die 46. The position of the stripper plate can be adjusted up or down by inserting a filler under the head of the shoulder bolt or at the bottom of the body of the shoulder bolt. To increase the pressure of the spring, a filler can be installed at the lower end of the spring. Also, stronger springs may be used.

A female mold 54 having a cutting blade 56 , a mold surface 58 and a female mold cavity 60 is supported by the lower mold holder 42 , and the female mold cavity 60 is disposed on a discharge passage 62 formed in the lower mold holder 42 . It is open to

In order to obtain a decorative body having a laminated structure as shown in FIG. 1, the base body 26 is placed on a mold surface 58 with the decorative surface 25 of the base body 26 facing downward and the decorative portion aligned with the opening or cutting blade 56 of the female mold. It is obtained by punching out the base material. When the press is closed, as shown in FIG. 3b, the base body 26 is pressed against the stripper plate 44 and the male mold 46, and as the male mold 46 descends into the female mold cavity 60, the second spring 49 .51 is compressed,
A portion of the base body close to the decorative design is fixed by a stripper plate 44.

However, at this time, since the layers on each side of the base body 26 are relatively soft, the base body is pulled into the female mold cavity and the male mold 4
6 is deflected downward as shown in FIG. 3b, giving a deflection 68 to the decorative body. By completely lowering the male mold, the base body 26 is punched out along the vicinity of the design to obtain the decorative body 70.

This decoration falls and is collected from the female mold cavity 60 via the discharge channel 62 of the lower mold holder. Due to the deflection, the decorative body 70 consisting of the press of FIG. 3b
is dome-shaped.

In the present invention, the pressure support is elastically fixed to the female mold and the substrate is held flat on the surface of the male mold to prevent deflection.

Furthermore, the separation operation in which the stamped decoration is no longer collected from the base opening of the female mold cavity, and the decoration is reinserted into the cut edge of the basic body after punching by means of a pressure support and then ejected from the mold press Done on another workstation on the device.

As shown in FIG. 4a, the mold press apparatus has a male mold holder 80, a lower female mold holder 82, a work station 84 on the right and a work station 86 on the left. At the right-hand workstation the decoration is stamped from the base and reinserted into the base, and at the left-hand workstation 86 the stamped decoration is ejected from the base by a male die. A die press device is connected to the press drive by a shaft 85 and fastened to the base of the press at a lug 87.

The right workstation 84 has a lower mold holding section 82.
It has a female mold attached to it. The female mold has a mold cavity 92 in which a pressure support 94 is resiliently mounted on an assembly L consisting of a spring 96 and a shoulder bolt 98. Here, a plurality of spring and shoulder bolt assemblies may be used to support the pressure support, which is determined by the dimensions of the decoration to be stamped. The shoulder bolt 98 is threaded and its tip is screwed into the pressure support. The pressure support in the mold cavity can be adjusted in its resiliency using methods similar to those described above with respect to stripper plate 44 in FIG. 3, thereby providing sufficient repulsion to cause the substrate to deflect. This prevents the plastic covering from deforming.

At the head of the mold press, a male mold 102 is mounted in a male mold holder 80, which is also surrounded by an adjacent stripper plate 104. Third, the stripper plate 104 is attached to a spring and shoulder bolt assembly, of which there are four sets, but only two are shown. As shown in the figure, the spring 106 is attached to the shoulder pad) 1
08, and the shoulder bolt is attached to the stripper plate (104) with a screw cut at the bottom. The attachment of the stripper plate can be adjusted as described above.

The workstation 86 on the left has a second male mold attached to the male mold holder 80 and a female mold 112 attached to the lower mold holder 82 and having a mold surface 114, with a mold cavity 116 of the female mold attached to the lower mold holder 82. Collection path 1 formed in the mold holding part 82 of
It opens at 20.

The male type 86 is an assembly 115 of a spring and a shoulder bolt.
a, surrounded by a stripper plate 115 reciprocably mounted on 115b.

The stripper plate 115 acts similarly to the stripper plate 104 previously described and the stamped decoration is projected and flattens the substrate as it leaves the edge of the male mold.

The operation of the embodiment of the present invention will now be substantially explained, with reference to the illustrated pressure support 94 being elastically attached to the spring and shoulder bolt assembly -1-.
Those skilled in the art will readily recognize that other elastic devices may be used in place of the spring and shoulder bolt assembly shown, such as rubber bodies, compressed air, or hydraulic cylinders. .

The operation of the die press is shown in Figure 4b. In that figure, a substrate with an array of cross-linked plastic coated designs as shown in FIG. It is placed close to the cutting blade 100 of. The spacing between each design on the substrate I- is the same as the first design (the design on the right workstation) and the second design (the design on the left workstation).
1), it is preferable that when the first design is punched out, the second design is located at the second position of the female die 112 at the same time. The sizes of the molds of the left and right workstations -1- are normally set so that when the first and second designs are in the punching and ejection process, the third design is located between the left and right workstations.

To explain the punching operation, when the male die holder 80 is closed, the male die 102 comes into contact with the base body and presses the base body against the pressure support. The resiliency of the spring 96 is such that the pressure support 94 resists the pressure when the male mold 102 is lowered, thereby preventing deflection of the base body.
It also prevents the decoration or its transparent plastic covering from being scratched, crushed, or deformed. The elasticity of the spring 96 and pressure support can be adjusted using fillers or by selecting the spring. As a result, the base body is not distorted by punching.

The punched parts are returned to their original edges and sent to the workstation for the next ejection. If the elasticity of the spring is too strong, the punched portion will be distorted, and if it is too weak, the cut edge will not return to its original shape.

When the male mold holder 80 is completely lowered, the pressure support 94 sinks under the cutting edge of the cutting blade 100 due to the pressure of the male mold 102 and the base 2
6 will be pressed against the blade 100. Decorative body 126 is then stamped from the base body and pushed into female cavity 92. Stripper plate 1 when press closes
04 clamps the base part around the decorative body, and the core part is the blade 100
Avoid bending around to help get sharp vertical cutting edges.

After stamping the decoration 126 from the base body 26, the press opens and the male die 102 separates from the base body. Then the pressure support 94
Since the pressure applied to the cutter is released, the pressure support returns to its original position slightly above the cutting edge of the cutting blade. The ornament 126 is then reinserted into the base body. At this time, since the stripper plate 104 is still in pressure contact with the base, the base does not stick to the male mold 102. The pressure support also does not push the substrate away from the female mold surface when reinserting the ornament 126 into the substrate.

On the other hand, since the decorative body previously reinserted into the base body has been moved to the left workstation 86, the left workstation 86 is punched out at the same time as the decorative body is punched out at the right workstation. Now the press mold is closed. Thereby, the decorative body 126 punched by the second male die 110
protrudes from the base body 88 into the cavity 116 of the female mold 112.

The decorative body 126 then falls under its own weight and leaves the press in the passage 1.
20 can be collected. Figure 4 shows a fully automated system in which decorations are punched out in succession at the right workstation and ejected at the left workstation each time the die press is operated; The ejection operation may be performed manually. In this case, a mold press with only a right-hand workstation is used, in which the decoration cut from the base body is manually ejected.

Figures 5a and 5b show another embodiment of the invention.

In contrast to the previous embodiment, in this embodiment the female type is the male type! There are four holes on three sides, which fit into the male mold when it is placed still.

Referring to FIG. 15a, the mold press has two sets of workstations as in the previous embodiment, with a punching workstation on the right side and an ejection workstation on the left side.

The ejection workstation may be replaced by an equivalent manual operation. The punching workstation 140 and the ejection workstation 142 share an upper mold holder 144. In a punching workstation, a female die 146 mounted on an upper die holder 144 is in a relationship with a male die 148 attached to a lower die holder 150 to enable die cutting. - Upper mold holding part 1
44 is connected to a mechanical press drive shaft (not shown) by a shaft 152, and the lower mold holder 150 is fixed to the press base.

- The lower mold holder is aligned by a guide shaft (not shown). The male mold 146 has a mold cavity 154 within which a pressure support is resiliently attached to a spring and shoulder bolt assembly.

The spring of the assembly is fitted into a shoulder bolt, which is threaded onto the pressure support 156. It goes without saying that a plurality of spring and shoulder bolt assemblies may be used depending on the design of the decorative body.

A table 162 is attached to and resiliently supported by an assembly consisting of a spring 166 and a shoulder bolt 168 similar to the assembly described above in the lower mold holding section. The height y of the table 162 and the elasticity of the springs can be adjusted by using padding as described above. table 162
The number of spring and shoulder bolt assemblies supporting the can be changed depending on the size and design of the emblem or plaque to be cut, and in the illustrated embodiment six wooden shoulder bolts are used. However, the three pieces of wood are on the rear side of the shoulder bolt shown.

The male die 148 is attached to the lower die holder 150 and its top is located within the opening 147 of the table 162.

As a result, the table 162 is able to move back and forth (downward), and the base body resting on the male mold 148 is peeled off after punching.

The substrate is mounted in the workstation 140 for stamping with its design side 25 facing the male mold 14B and the plastic coated design aligned with the blade 176 of the male mold. Female blade 176 is preferably a steel blade as shown. '' A part of the mold holder 144 descends and presses the female mold 14B against the base body 26 and the male mold 14B. At this time, since a pressure support is located within the female mold, the pressure support comes into contact with the base of the male mold to prevent the base from deflecting.

When the female mold 146 further descends and fits into the male mold 148, the table 16 elastically held by the mold holding part 15LI-
2 is pushed down slightly. At this time, the pressure support 156 appears as if it is being pushed down from the female mold surface. The decorative body is then punched out from the base body.

When the pressure is released, the table 162 uses its elasticity to restore the base body 26 while keeping it in contact with the mold surface of the female mold 146.
As a result, the pressure support acts as if to restore itself to its original position, reinserting the decoration into the base.

The workstation 142 on the left is the upper mold holder 14
4, a resiliently held table 162 and a guide groove 188. Guide groove 18
8 is defined by a guide wall 178 which is slidably received in a passage 180 formed in the lower mold holding part 150. When the upper mold holder is lowered at the left workstation, the substrate is held elastically between the table 162 and the stripper plate 182.

Stripper plate 182 surrounds male die 174 and spring and shoulder bolt assembly 18
It goes without saying that it is elastically and adjustably mounted on 4.

The male mold 174 then projects the decoration 82 being cut through the opening 176 of the table 162 and into the guide groove formed by the guide wall 178 . The decoration is thereby ejected from the press through a passage 180 provided in the lower mold holder.

(Effect) In the method shown in Figure 4, the decorative body is punched out from the base,
Although there is a tendency for the edge to be slightly chipped when it is protruded, this tendency is extremely small and hardly reduces the commercial value of the decoration, and in the example shown in Fig. 5, the edge is almost never chipped. It does not occur.

It has been found that the plastic sheath shown in FIG. 2 is compressed into a spherical shape when it is stamped, and when the compression is removed it expands so that its edges bulge out slightly. However, in the embodiment shown in Fig. 5, when the decorative body does not protrude, the side surface presses against the plastic covering.
Edge chipping rarely occurs.

Although the methods listed here are preferred embodiments of the present invention, it is understood that the present invention is not limited thereto and that various changes may be made without departing from the scope of the claims of the present invention. There will be.
