Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forming an embossed pattern such as a picture on a leather member used for a leather product such as a wallet, a regular bag, a handbag and the like.

 Alternatively, the present invention relates to a method for manufacturing the device.

[Prior art and its problems]

2. Description of the Related Art A commercial method of giving a prominent character or a specific design or character to a leather product such as a wallet or a handbag to stimulate a consumer's purchasing mind is generally performed.

Conventionally, as a means for forming a pattern such as a character on a leather product, a method of simply attaching a third member such as an emblem, a method of manually forming a pattern for each leather product, or a method shown in FIG. As described above, a pattern is engraved on one metal (copper, zinc, brass, etc.) plate and the other metal flat plate 8 is engraved.
There was one that pressed against the leather member 5 placed on top.

However, when a third member such as an emblem is stuck, the adhesive is easily peeled off, and the adhesive remains after peeling, which is not preferable in terms of aesthetics.

Further, when a hand-made pattern is formed, there is a disadvantage that mass production is not possible and the cost increases.

Furthermore, when a metal flat plate is used, there is a disadvantage that if the pattern becomes complicated (the relief of the relief pattern becomes finer), it is not possible to provide sufficient relief. That is, since the fine and rough portions 7b and the rough portions 7a of the relief pattern are pressed by the metal plate 8 at the same pressure (FIG. 5 (b)), the leather member 5 corresponds to the fine portion 7b of the relief pattern. However, they could not be sufficiently represented in three dimensions (FIG. 5 (c)).

Therefore, an object of the present invention is to provide an embossed pattern forming apparatus for a leather member that can set the state in which the leather member is most easily deformed and can accurately form the unevenness of the embossed pattern.

Another object of the present invention is to provide a method for manufacturing an embossed pattern forming apparatus that can manufacture the above apparatus most simply and surely.

[Means for solving the problem]

In order to solve the above problems, the present invention relates to an apparatus for forming an embossed pattern on a leather member by pressing the leather member with a predetermined pressure to form an embossed pattern on the leather member. The intaglio plate is provided with a relief that is provided with a pattern substantially the same as the relief pattern, and has a heating means on at least one of the relief and the relief. Is characterized in that the interval between the intaglio plate and the relief plate in the portion where the density of the surface is fine is smaller than the interval in the portion where the density of the unevenness is low.

Alternatively, a leather member is placed between the intaglio and the letterpress, and a method of manufacturing an embossed pattern forming apparatus that forms an embossed pattern by pressing the intaglio against the letterpress is used. A plate making step, an intaglio setting step of setting an intaglio on a pressing member pressed on the fixed base, and when pressing the pressing member on the fixed base, setting the resin member on the fixed base at a position corresponding to the intaglio. The resin member setting step, the plate setting step of pressing the intaglio plate and the resin member to determine the overlaid portion, and attaching the third member to the overlaid portion to reduce the density of the unevenness in the relief pattern to the fine portion. It is characterized in that it is provided with a build-up step of providing a build-up and forming a relief plate.

[Action]

Since the present invention is configured as described above, it is possible to accurately form the relief of the relief pattern by the action of the intaglio and letterpress having a special structure.

Or, by the action of the third member attached to the letterpress,
The embossing pattern forming device can be manufactured most simply and reliably.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the description, the same elements will be denoted by the same reference symbols, without redundant description.

FIG. 1 is a side view showing an embodiment of an embossed pattern forming apparatus for a leather member according to the present invention. The device for forming an embossed pattern of a leather member is basically composed of a relief plate 2 and an intaglio 1. The relief plate 2 is attached to a fixed base 3 and the intaglio 1 is attached to a pressing member 4. These are mounted with screws or the like, but may be mounted so that they can be moved to some extent by double-sided tape or rail connection. Alternatively, one may be attached as a magnetic material and the other as a magnet.

One end 4a of the pressing member 4 is pin-connected to the fixed base 3 so as to be rotatable about the fulcrum 3a as a central axis. At the other end of the pressing member 4, a handle 4b is formed. Therefore, when the handle 4b is pushed in the direction of the arrow as shown in FIG. 1 (b), the pressing member 4 is rotated around the fulcrum 3a, and the intaglio 1 is pressed against the relief 2 by a large force. Note that a heating means 4c such as a heating wire is embedded in the pressing member 4, and the intaglio 1 can be heated to a constant temperature by a heat conduction effect.

The intaglio 1 is engraved with the same pattern as the relief pattern to be formed on the leather member 5, and the relief pattern 2 is provided with the same pattern as the relief. The important thing here is that
When the intaglio 1 and the letterpress 2 are overlapped as shown in FIG. 1 (b), there is a difference in the distance between the intaglio 1 and the letterpress 2 (see FIG. 2). That is, among the highlights pattern, unevenness of density is coarse portion 1a, 2a and fine portions 1b, to distinguish the 2b, the intaglio and letterpress in rough areas the distance d ₂ between the intaglio and letterpress in fine parts It constitutes less than the distance d _1.

This is because a relatively high pressure cannot be applied to a complicated portion of the pattern (a portion having a high density of irregularities) to sufficiently provide a relief effect (three-dimensional effect). The degree of difference between d ₂ and d _1, but is intended to change the density or material of the unevenness is defined by an experiment or empirical rule or the like. It is needless to say that some gaps are provided when the intaglio 1 and the relief 2 are overlapped in consideration of the thickness of the leather member.

Hereinafter, the operation of this device will be described. First, the leather member 5 is placed on the letterpress 2 with the intaglio 1 opened (FIG. 1A).

Next, the power switch of the heating means 4c attached to the pressing member 4 is turned on, and the heating means 4c is heated to about 100 ° C to 120 ° C. Therefore, the intaglio 1 is heated to the above temperature.

Next, the handle 4b is pressed in the direction of the fixed base 3 and the leather member 5 is pressed by the intaglio 1 and the relief 2. 100 ° C ~ 120 for intaglio 1
C., and the embossed pattern is formed in a state where the leather member 5 is most easily deformed. According to the experiment, 100 ° C for camel in cowskin, 1 for dark brown
10 ° C and 120 ° C for black are desirable.

In this embodiment, the heating means 4c is mounted on the intaglio 1 side, but it may be on the intaglio 2 side. Further, the letterpress 2 is attached to the pressing member 4 and the intaglio 1 is
May be mounted on top.

In this embodiment, the lever is used as the pressing means. However, a pressure type (hydraulic, hydraulic) jack or the like may be used so that a constant pressure can always be applied. By configuring so that a constant pressure can be constantly applied, the accuracy and reliability of the device can be improved.

Next, an embodiment of a method for manufacturing an embossed pattern forming apparatus for a skin member will be described with reference to FIGS. 3 and 4. FIG.

In step 11, a predetermined pattern or the like is made on an intaglio by hand engraving or the like based on the original image.

Next, the completed intaglio 1 is attached to the pressing member 4 (step 12).

In step 13, as shown in FIG. 4 (a), the synthetic resin 2 mainly composed of polyamide is placed on the fixing base 3.
The synthetic resin 2 is finished to a shape close to a relief pattern, and particularly, a complicated portion of the pattern (a portion having a high density of irregularities) is supplemented by a third member described later. The material of the synthetic resin is not particularly limited to a polyamide resin, and may be a plastic, a ceramic, or the like as long as the material has a strength capable of deforming the leather member.

In Step 14, the intaglio plate is pressed against the synthetic resin 2 (FIG. 4 (b)), and the necessary portion of the overlay and the extent of the overlay are checked. The exact degree of overlay is determined by trial-pressing the leather member while comparing it with the original image.

In step 15, based on the information obtained in the plate matching step 14, the relief printing of the letterpress is performed by the third member 6 (FIG. 4 (c)). Specifically, a piece of paper or the like having a certain thickness is cut and pasted to form a fine overlay. The material used for the cladding is not particularly limited to paper, has a certain thickness, has a strength enough to deform the leather member in the state of being adhered, and has a temperature of 100 ° C to 120 ° C. Any material that does not deform even when subjected to heat of ° C may be used. Thus, a predetermined relief is formed by repeating the build-up (FIG. 4 (d)).

〔The invention's effect〕

Since the present invention is configured as described above, the pressing force can be made different depending on the density of the unevenness in the relief pattern, and the precision of the relief pattern can be improved. Therefore, the present invention can be applied to a particularly complicated character, and a sufficient three-dimensional effect can be exhibited.

In addition, the method for manufacturing a plate according to the present invention has a configuration in which a rough relief plate shape is formed by a synthetic resin or the like, and particularly a portion having a fine density of unevenness is supplemented by a third member.
High-accuracy plates can be reliably manufactured in a short time.
