DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved hydraulic transfer printing method for printing on a non-planar surface such as a curved surface or an irregularly-shaped surface, or on a surface to be transferred mainly composed of a flat surface. . In particular, the present invention relates to a method which is effective for a large-sized transfer member whose transfer surface has a large stop.

[0002]

2. Description of the Related Art In recent years, there has been a high demand for higher design of plastic molded articles and the like, and surface decoration has been performed by various methods such as attaching a decorative sheet, but the surface to be decorative is non-planar. In the case or when a continuous pattern is applied to a plurality of planes such as a plane like a peripheral surface of a box-shaped transfer object, a hydraulic transfer printing method has been used as one of them. Was.

However, in the conventional hydraulic transfer printing method, for example, according to the method disclosed in Japanese Patent Publication No. Sho 60-50597, a liquid in a liquid tank is caused to flow to generate a liquid flow. The transfer film is floated along with the transfer film, and is lowered while moving the transfer object at the same speed as the transfer film so as to have a relatively stationary relationship with the moving transfer film. The transfer film is brought into contact with the liquid and allowed to settle in the liquid, and the transfer film is applied to the transfer surface of the transfer object by using the liquid pressure, and then the transfer object is lifted up. The transfer film support on the surface is removed, and the pattern formed on the transfer film is transferred to the transfer surface. When the transfer film floats on the liquid surface, it swells with the liquid and is stretched.Therefore, the speed obtained by adding the stretching speed to the transfer film movement speed is the actual transfer film movement speed. By adjusting to the actual moving speed, when the transfer film on the liquid surface comes into contact with the transfer surface of the transfer object, the transfer film is not pulled or pressed against the liquid flow direction to generate wrinkles or the like. Like that.

Further, in the method disclosed in Japanese Patent Publication No. 60-58718, a pattern to be transferred on a transfer film floating on a liquid surface is easily adhered to a transfer surface of a transfer object. There is provided a method for maintaining a wet state of a picture when a transfer surface and a transfer film come into contact with each other. That is, when the transfer film comes into contact with the object to be transferred, the ink constituting the picture is swelled by using the activator as the swelling liquid, thereby exhibiting the tackiness. By such a method, when the transfer film floating on the liquid surface and the transfer surface come into contact with each other, the transfer film is cleanly attached to and transferred to the transfer surface.

In the above method, the transfer film is transferred onto the transfer surface by the up and down movement of the transfer object. When the transfer object has a substantially columnar shape, the cross section of the column is reduced. There is also a method in which the transfer film is transferred to the transfer surface on the side surface of the transfer object by contacting and sinking with the transfer film on the liquid surface while rotating the central axis as a support and rotation axis of the transfer object. According to this method, even if the size is large,
When the surface to be transferred is a side surface of a substantially cylindrical object, there is an advantage that a pattern with substantially uniform elongation can be transferred regardless of the location of the surface to be transferred.

[0006]

However, in the conventional hydraulic transfer printing method described above, it is impossible to apply a picture in a shape in which the transfer surface of the transfer object is large and the aperture is deep. The problem was that adaptation was extremely difficult. However, in recent years, there has been an increasing demand for decoratively decorating the surface of large molded articles such as television cabinets so that the articles have higher designs. These products do not have complicated irregularities and simple ones are box-shaped mainly with flat surfaces, but if you want to make a continuous pattern on both sides and the top surface, It is not possible at all with the method of transferring the transferred object vertically up and down with the top surface facing down on the transfer sheet that has a very deep drawing shape and simply floats the transferred object on the liquid surface. there were. That is, for example, when the shape of the transfer object is transferred to the side surface of an object on a circular cylinder having a circular cross section, if the transfer object is small and short, the longitudinal direction of the transfer object is substantially upright or sideways. If the transfer film floats on the liquid surface while it is lying down, the transfer film adheres and transfers to the transfer target even if the transfer film is partially stretched. Transfer is possible for a while. However, if the size of the transfer film becomes large even with a shape similar to the above, the transfer film wrapping around the transfer surface of the transfer target is transferred while the transfer film is extremely stretched, that is, the aperture is deepened, and the transfer is deepened. At the same time, even if it gets entangled, the transfer film is stretched too much, and the pattern of the original pattern formed on the transfer film is greatly collapsed, and the expected design effect is no longer exhibited It was impossible to do it.

In the case where the shape of the transfer object is a square or a simple shape in which the corner is rounded, there is a method in which the molded product is rotated by a roll transfer method while rotating. However, this method cannot cope with a three-dimensional shape on the side surface. Accordingly, an object of the present invention is to provide an improved method of a hydraulic transfer printing method suitable for producing a three-dimensional molded article with a picture, which enables painting on a molded article having a large and deep drawing.

[0008]

In order to achieve the above-mentioned object, a liquid pressure transfer printing method according to the present invention comprises a step of swelling or dissolving a liquid stored in a liquid tank on the surface of the liquid. After applying the activator to the pattern forming surface of the transfer film having an arbitrary pattern formed on the support, the transfer film is floated with the pattern forming surface facing upward, and then the transferred object is parallel to the liquid surface. The transfer film was lowered into the liquid by contacting while rotating about the rotation axis to cause a part or all of the transfer object to settle in the liquid, and the part or the whole was settled below the liquid level. Thereafter, the transfer object is removed from the liquid, the transfer film is applied to the transfer surface of the transfer object, the support constituting the transfer film is removed from the transfer surface, and the pattern is transferred to the transfer object. A method for producing a three-dimensional molded article with a picture, characterized by that A. Further, in the above method, the operation of the rotation axis of the object to be transferred is performed by combining the vertical movement in the vertical direction and the horizontal advance operation in the rotation direction, so that the sedimentation of the transfer surface that is settled in the liquid tank is the highest. The transfer surface of the object to be transferred with respect to the surface assuming that the transfer film surface floating on the liquid surface is uniform at the position of the settling depth so that the settling depth of the set surface is substantially constant. The present invention provides a method for producing a three-dimensional molded article with a picture, characterized in that the object to be transferred is rotated about the rotation axis so that the object rolls without slipping.
In addition, a three-dimensional molded article with a picture obtained by the above manufacturing method is provided.

The present invention will be described below in detail with reference to the drawings. FIGS. 1 and 2 are explanatory views of a hydraulic transfer printing method suitable for manufacturing a three-dimensional molded article with pictures, showing an embodiment according to the present invention. FIG. 1A shows a state before transfer. In the method for manufacturing a three-dimensional molded article with a picture according to the present invention, the transfer film 1 having the picture 3 formed on the support 2 is floated on the liquid surface of the liquid tank 5 storing the liquid 6. The transfer film 1 floating on the liquid surface swells with the liquid. Further, in order to stably impart the adhesiveness to the transferred object 4 to the pattern 3 of the transfer film 1 floating on the liquid surface,
The activator has been applied.

On the other hand, the transfer object 4 illustrated in FIGS.
Has a substantially rectangular shape, and has a slight uneven portion 41 on a side surface thereof. The transfer object 4 is supported in a space by an appropriate support 7. In the figure, a joint 71 that bends freely.
However, the shape and mechanism of the support 7 are not particularly limited, and any suitable means may be selected as appropriate from the manufacturing apparatus and the shape of the object to be transferred. The simplest support means is a human hand, but for industrially efficient transfer, a support tool that moves along a continuous rail is generally used. The manufacturing method according to the present invention is characterized in that the object to be transferred is rotated so as to satisfy a certain condition. As means for realizing the rotation,
For example, a spatial transition trajectory in which a preferable rotation axis moves is determined in advance from the outer shape of the transfer surface of the transfer object, and a hanging rail of a support and a rotation mechanism of the transfer object along the transition trajectory are provided. It is good to keep it.

In the transfer process, the transfer object 4 is lowered into the liquid 6, and the transfer surface (side surface in the figure) is transferred to the transfer film 1.
FIG. 1B shows a state in which the contact is made. The transfer film is sufficiently wrapped around and transferred to the uneven portion 41 on the side surface of the object to be transferred since the aperture of the unevenness is not deep. At this time, the depth at which the transfer target is settled in the liquid 6 is as shown in FIG.
If the concave and convex portions 41 on the side surface of the transferred object 4 as shown in the above state are irregularities of a sufficiently curved surface if the transferred object is lowered in the vertical direction, it is assumed that there is no unevenness on the side surface. It can be settling depth. If the uneven portion 41 is convex enough to be considered, the uneven portion 41 is treated as a separate transfer surface, and the sedimentation depth of the convex portion and the sedimentation of the surface having the uneven portion 41 other than the uneven portion 41 are determined. The object to be transferred is rotated so that each of the depths is substantially the same. In the next operation, the transferred object 4 is box-shaped in this case, and the next transfer surface is perpendicular to the previous transfer surface.
Is rotated by 90 ° to reach the state shown in FIG. In this case, as a point of the present invention, the rotation of the rotation axis of the transferred body 4 is performed while vertically moving the rotation axis, and the rotation axis is also rotated so as to advance in the horizontal direction in the rotation direction.
The surface of the transfer film 1 floating on the liquid surface is positioned at the above-mentioned settling depth such that the settling depth of the most settled surface among the surfaces of the transfer object 4 settling in the liquid tank is substantially constant. The transfer object 4 is rotated so that the transfer surface of the transfer object 4 rolls without slipping with respect to the surface assumed to be uniform. Thereafter, the transfer object 4 is rotated to transfer the remaining transfer surface to the state shown in FIG. 2D, and then the transfer object 4 is lifted, and the transfer surface of the transfer object 4 is transferred. The support 2 is removed with an appropriate liquid such as water while leaving only the pattern 3 from FIG.
A three-dimensional molded product 8 with a picture as shown in FIG. Normally, the pattern 3 transferred to the transfer surface of the transfer object 4 is liable to fall off because the surface strength is insufficient as it is, and therefore, a paint or the like is overcoated according to an ordinary method.

In the present invention, the rotation axis of the object to be transferred may be regarded as the rotation axis with the joint 71 if the support for actually supporting the object to transfer has the joint 71 described above. Can also. However, in the cross-sectional shape of the transfer-receiving surface of the transfer-receiving member as shown in FIGS. 1 and 2, the axis passing through the center coordinates of the figure shown by the cross-section may be used as the rotation axis. Since this is only a hypothetical definition, the center coordinates need not be exactly the center. In some cases, the support axis may be a support axis that supports the object to be transferred in accordance with the rotation axis that passes through the center coordinates of the figure. On the other hand, when it is difficult to provide a support shaft at the position of the rotation shaft due to the shape of the transfer object, the rotation shaft and the support shaft are different. As described above, basically, the rotation axis of the support means the center coordinates of the cross-sectional figures of the plurality of transfer surfaces of the transfer object, but is a hypothetical hypothesis, and is actually an actual machine. It does not need to coincide with the rotation axis of the general support. In short, as described above, the operation of the rotation axis of the transfer target is performed by combining the vertical movement in the vertical direction and the horizontal forward movement in the rotation direction, and the transfer surface settling in the liquid tank. The transfer film is transferred to the surface assuming that the transfer film surface floating on the liquid surface is uniform at the position of the settled depth so that the settled depth of the most settled surface is substantially constant. As the rolling surface of the body rolls without slipping,
The object is to rotate the transfer object about a rotation axis.

1 and 2, the liquid 6 in the liquid tank 5 has been statically described. However, when the liquid 6 flows in the liquid tank 5 to form a liquid flow, the liquid 6 The transfer surface is relative to the swelling speed of the transfer film 1 flowing along with the flow, or more specifically, the swelling speed of the transfer film 1 swelling and expanding in contact with the liquid 6 and the speed of the liquid flow. When the object to be transferred is rotated while being moved so as to be in a stationary position, good results suitable for continuous production can be obtained while preventing excessive elongation and wrinkling of the transfer film.

[0020]

According to the structure of the method for producing a three-dimensional molded article with a picture according to the present invention, the surfaces to be transferred of the object to be transferred do not slip on the transfer film surface floating on the liquid surface. As described above, the transfer is performed while the transfer target is being rotated while being rolled on the transfer film. As a result, the transfer target film is not extremely stretched depending on the position of the transfer surface of the transfer target.

<< Embodiment >> A description will be given below with reference to FIGS. 1 and 2. First, the following materials were prepared as transfer materials. Transfer film: Polyvinyl alcohol resin film (Hi-Selon C-
300 with a thickness of 40 μm)
A total of 15 parts by weight of nitrocellulose and an alkyd resin, 5 to 13 parts by weight of a pigment, and the rest were gravure-printed with an ink containing toluene as a solvent component to form a multicolored pattern 3 to obtain a transfer film 1. . Activator: 21 parts by weight of sedimentable barium, 27 parts by weight of butyl cellosolve, 27 parts by weight of butyl carbitol acetate, and 10 parts by weight of dibutyl phthalate were mixed with 15 parts by weight of the above resin. Transfer object: A box-shaped television cabinet was used as the transfer object 4. The material is made of ABS (acrylonitrile-butadiene-styrene copolymer) resin, the size is 60cm in height,
It is 80 cm wide and 35 cm deep.

A solution prepared by applying the activator at 13 g / m ² on the printing surface side of the pattern 3 of the transfer film 1 and storing water 6 adjusted to 30 ° C. so that the pattern printing surface is on the upper side. It floated on the water surface of the tank 5 (FIG. 1A). On the other hand, the transfer target 1
Was held by the support 7 having the joint 71 that bends freely. After one minute, first, the transfer-receiving body 4 was set down below the liquid surface by contacting the transfer film 1 floating on the water surface with the side surface of the transfer object 4 facing down [FIG. 1 (b)]. Next, in order to bring the top surface into contact with the transfer film 1, the object to be transferred was rotated by 90 ° about a rotation axis parallel to the water surface. At that time, the edge of the boundary portion between the side surface and the top surface is set to be substantially the same as the sedimentation depth when the side surface was previously settled below the liquid surface, that is, it does not sink deeper. In this way, the support 7 of the transferred object 4 is moved upward,
Was rotated while bending. Further, the support 7 of the transferred object 4 was rotated while being moved forward along the rotation direction so that the horizontal position of the edge was not substantially changed in the rotation direction. In this way, the top surface of the transferred object 4 was gradually brought into contact with the transfer film 1 floating on the water surface from the side close to the side surface and settled below the liquid surface [FIG. 2 (c)]. Next, the transferred object 4 was rotated by 90 ° to transfer the side surface opposite to the side surface.
At this time, the transfer member 4 was rotated in the same manner as the method of rotating the transfer-receiving member 4 from the side surface to the top surface (FIG. 2D). Next, the transfer object 4 was taken out of the liquid, and thereafter, the support 2 of the transfer film 1 attached to the transfer surface was removed by water washing according to a known conventional method. In this way, a three-dimensional molded product 8 having a picture transferred to the three sides, that is, both sides and the top side, was obtained (FIG. 3). In the three-dimensional molded article 8 obtained, the pattern 3 is clearly transferred on all three sides, and the pattern 3 of the transfer film 1 is not excessively stretched or wrinkled, and the transfer film 1 is not formed. Thus, a uniform and uniform pattern 3 almost similar to the pattern 3 printed on the image was transferred.

Comparative Example 1 Using the same transfer material as in the example, only the transfer was performed in the following manner. On the printing surface side of the pattern 2 of the transfer film 1, the activator is applied at 13 g / m ² , and a liquid tank 5 storing water 6 adjusted to 30 ° C. so that the pattern printing surface is on the upper side. Floated on the water. One minute later,
The top surface of the transfer-receiving body 4 was lowered downward, and was brought into contact with the transfer film 1 floating vertically above the water surface from the top surface and settled below the liquid surface. The sedimentation was continuously performed until the side surface of the object to be transferred also entered the water, and thus the transfer film 1 was also brought into contact with the side surface and transferred. Next, the transfer object 4 was taken out of the liquid, and thereafter, the support 2 of the transfer film 1 attached to the transfer surface was removed by water washing according to a known conventional method. In this way, a three-dimensional molded article with a picture intended to transfer a picture pattern to three sides, that is, both sides and a top face was obtained. However, the obtained three-dimensional molded product with a picture has a particularly large elongation of the pattern on the side surface, the elongation is not constant as a whole, and the design feeling of the pattern formed on the original transfer film has been impaired. .

Comparative Example 2 Using the same transfer material as in the example, transfer was performed in the following manner. On the printing surface side of the pattern 2 of the transfer film 1, the activator is applied at 13 g / m ² , and a liquid tank 5 storing water 6 adjusted to 30 ° C. so that the pattern printing surface is on the upper side. Floated on the water. On the other hand, the transferred object 1 was held by a support such that the center of the transferred object 1 was used as a support axis and a rotation axis so that the rotation axis was horizontal.
One minute later, first, the transfer-receiving body 4 was set down on the liquid surface by contacting the transfer film 1 floating on the water surface with the side surface of the transfer-object 4 facing down. Next, in order to bring the top surface into contact with the transfer film 1, the transfer object was rotated 90 ° about a rotation axis parallel to the liquid surface. At this time, the transfer member 4 was rotated so that the vertical position of the support shaft of the support member became constant. The horizontal position of the support shaft was rotated while being moved forward along the rotation direction. In this way, the top surface of the transfer-receiving body 4 was gradually brought into contact with the transfer film 1 floating on the water surface from the side close to the above-mentioned side surface and settled below the liquid surface. Next, the transferred object 4 was rotated by 90 ° to transfer the side surface opposite to the side surface. At this time, the transfer target 4 from the side surface to the top surface is also used.
Was rotated in the same manner as in the above method. Next, the transfer-receiving member 4 was taken out of the liquid, and the support 2 of the transfer film 1 attached to the transfer-receiving surface was removed by washing with water according to a known conventional method. In this way, a three-dimensional molded article with a picture intended to transfer a picture pattern to three sides, that is, both sides and a top face was obtained. However, the obtained three-dimensional molded product with a picture had a large pattern elongation at the end, and the elongation was not constant as a whole, and the design feeling of the pattern formed on the original transfer film was impaired. .

[0025]

Since the present invention is configured as described above, it has the following effects. ADVANTAGE OF THE INVENTION According to the manufacturing method of the three-dimensional molded article with a picture according to the present invention, there is an advantage that painting can be performed even on a large and deeply drawn molded article. In addition, the pattern transferred to the molded product is less likely to be partially stretched, cut off, or wrinkled, and a pattern similar to the pattern formed on the original transfer film that is uniform and uniform. Since it is possible, it is possible to provide a high-quality and high-designed painting, which has never existed before. Accordingly, a three-dimensional molded article with a high design feeling can be obtained.
