DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to punching of a base paper such as cardboard, corrugated cardboard, plastic sheet material, laminated material, etc., by pressing a die with a press machine such as a punching machine so that a contour line is formed and penetrated. The present invention relates to a paper product, a method for producing the paper product, and a die used directly for carrying out the method.

[0002]

2. Description of the Related Art Conventionally, when characters or figures are displayed on a paper product such as a box or a carton for the purpose of discriminating contents or advertising, the printing is generally performed on base paper. . On the other hand, printing for the purpose of discriminating contents, advertising, and the like is too general and hardly left to a customer's impression, and the use of ink not only causes environmental pollution but also makes recycling difficult. As a result, the product image of the paper product may not match the corporate image of the provider of the product, and in order to solve such a problem, a natural display method instead of printing is demanded.

[0003]

However, in such a conventional method for producing paper products, since the base paper on which characters and graphics are already displayed by printing is punched out by a die, the process of displaying characters and graphics is performed. The punching process is required and it is time-consuming, and in general, the display process of these characters and figures and the punching process are often performed in different places. There is a problem that it becomes high. In addition, when characters or figures are displayed by engraving instead of printing, if the portion corresponding to the engraving and the extraction blade are integrally formed by corrosion, there is a problem that the manufacturing cost of the die becomes extremely high.

An object of the present invention is to provide an engraved paper product simply and in a shortest time. A fourth aspect of the present invention has the object of clearly displaying the entire engraving without manufacturing the entire template with metal, in addition to the object of the third aspect of the present invention.

[0005]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, a material different from a cutting blade is used at a position not overlapping with a contour line punched by the cutting blade. A paper product characterized in that a mark, such as a character or a figure, formed by pressing the formed corroded plate is recessed at the same time as the cutting timing of the contour line by the extraction blade. According to the second aspect of the present invention, in accordance with the pressing of the template against the base paper, the leading edge of the extraction blade is pressed against the base paper to start cutting of the contour line. Press the tip of the corroded plate, on which letters and graphics are projected and formed with a different material, against the surface of the base paper, and then move the tip of the cutting blade to the back of the base paper to complete the cutting of the contour line. A method of manufacturing a paper product, wherein the leading end reaches an intermediate position in the thickness direction of the base paper, and pressing of the template against the base paper is completed in this state. According to a third aspect of the present invention, a corroded plate having characters and / or graphics formed of a different material is protruded from the surface of the template at a position not overlapping with the cutting blade, and the tip of the corroded plate is formed from the surface of the template. The protrusion amount from the surface of the template to the tip position of the blade is slightly lower than the protrusion amount. According to a fourth aspect of the present invention, in the configuration of the third aspect of the present invention, a metal table is vertically penetrated through the template, and a corroded plate having a smaller area is placed on the upper surface of the metal table. It is characterized in that a configuration in which the upper surface of the metal base and the corroded plate are fixed is added.

[0006]

According to the first, second and third aspects of the present invention, simultaneously with the cutting of the contour line by the cutting blade, the corroded plate is pressed to form a mark such as a character or a figure, so that the die cutting and the mark can be performed at one time. Is what is done. According to a fourth aspect of the present invention, in addition to the configuration of the third aspect, a metal table is vertically penetrated on the template, and a corroded plate having a smaller area is placed on the upper surface of the metal table. Since the configuration in which the upper surface of the base and the corroded plate are fixed to each other is added, the pressing force against the base paper from a press machine such as a punching machine is uniformly transmitted to the entire surface of the corroded plate via the metal base.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, as shown in FIGS. 1 to 3, a paper product A is a box-mounting board constituting a box or a carton, for example. An extraction blade B1 for forming the line A1,
The drawing shows a case in which a pressing rule B2 having a substantially U-shaped cross section for forming the folding line A2 is separately provided, and the base paper P used in the method of manufacturing the paper product A is a thick paper having a plain surface.

[0008] The punching die plate B is formed into a flat plate having a conventionally well-known structure such as a plywood or a metal plate, and is detachably attached to a lift table of a press machine such as an automatic flat-sheet punching machine, a big press, and a staple. It is attached. As shown in FIG. 2, the template B has a corroded plate in which characters and figures are formed of a different material at positions not overlapping with the extraction blade B1 for the contour line A1 and the pressing rule B2 for the bending line A2. 1 is protruded, and the amount of protrusion from the surface of the template B to the tip 1a of the corrosion plate 1 is made slightly lower than the amount of protrusion from the surface of the template B to the tip of the extraction blade B1. Specifically, for factors such as the material of the base paper P,
The amount of protrusion from the surface of the template B to the tip 1a of the erosion plate 1 is delicately adjusted so that the stamp A3 at the time of completion is a desired amount of dent. The amount of protrusion to the front end position of B2 is made lower, higher, or substantially the same.

The corroded plate 1 is formed by corroding an untreated metal such as a copper plate or a steel plate with, for example, dilute nitric acid or another corrosive agent, or by etching by electrolysis to remove portions other than the engraved portions. It is a conventionally well-known one manufactured. In the illustrated example, one in which only characters protrude and one in which only figures protrude are separately formed. However, the present invention is not limited to this, and a combination of characters and figures may be used.

Further, in the case of the present embodiment, a metal base 2 made of, for example, aluminum is penetrated up and down on the template B, and a corrosive plate 1 having a smaller area is provided on the upper surface of the metal base 2. Put the upper surface of the metal table 2 and the corrosion plate 1
For example, it is fixed by a fixing means 3 such as a double-sided tape or an adhesive.

Next, a method for producing the paper product A will be described. The above-described punching template B is attached to a lift of a press machine such as a punching machine, and a base paper P is set.
As shown by an arrow in FIG.
, The pressing blade B1, the pressing rule B2, and the corroded plate 1 protruding from the base paper P start to be pressed.

Along with this pressing, first, the tip of the extraction blade B1 is pressed against the base paper P, and the cutting of the contour line A1 into the base paper P is started. Slightly behind this, pressing rule B
2 and the tip 1a of the corroded plate 1 are pressed against the base paper P.

Thereafter, as shown by a two-dot chain line in FIG. 3, the leading end of the extraction blade B1 reaches the back surface of the base paper P, and the cutting of the outline A1 is completed. At this time, as shown in FIG.
If the rebound members B3 formed of a material that can be elastically deformed are provided along the extraction blade B1, the rebound members B3 are elastically deformed by contact with the base paper P as shown in FIG. Is pressed against the base paper P for which the cutting has been completed.

At the same time, the leading end of the pressing rule B2 and the leading end 1a of the corroded plate 1 reach the middle position in the thickness direction of the base paper P, and in this state, the pressing of the template B against the base paper P is completed, The plate B is returned to the original position and separated from the base paper P.

As a result, as shown in FIG. 1, the paper product A is punched along the contour line A1 without being clogged by the repulsive materials B3... The paper product A has a folding line A2 formed by a folding line A2. At the same time, the stamp A3 such as a character or a figure is depressed by the pressing of the corroding plate 1, so that the die cutting, creasing and stamping are performed at once. as a result,
The paper product A with the stamp A3 can be easily provided in the shortest time.

[0016] Therefore, compared with paper products in which characters and figures are displayed by printing, they are more likely to remain in the impression of customers, and because they do not use ink, they do not cause environmental pollution and are easy to recycle. The product image of the product and the corporate image of the provider of the product become natural, and the effect of giving a good feeling can be obtained.

Furthermore, in comparison with a method of producing a paper product in which a base paper on which characters and figures are already displayed by printing is punched out by punching, characters and figures etc. can be obtained simply by pressing the die B against the base paper P by a press machine such as a punching machine. The display step and the punching step can be performed at the same time, and no labor is required, and the manufacturing time of the paper product A can be reduced, and the manufacturing cost can be significantly reduced.

Further, a portion corresponding to the marking A3 and the extraction blade A1
As compared with a die that is integrally formed by corrosion, only the portion corresponding to the stamp A3 may be partially formed by corrosion, so that the manufacturing cost of the die can be significantly reduced.

Further, in the case of the present embodiment, a metal base 2 is vertically penetrated on the template B, and the corroded plate 1 having a smaller area is placed on the upper surface of the metal base 2 and these metal bases are placed. Since the upper surface of the base 2 is fixed to the corroded plate 1, the pressing force against the base paper P from a press machine such as a punching machine is uniformly transmitted to the entire surface of the corroded plate 1 via the metal base 2.

As a result, the entire stamp A3 can be clearly displayed without manufacturing the entire template B with metal. Therefore, inexpensive plywood or plastic can be used as the material of the template B,
The template B can be manufactured at a lower cost than when the entire template B is made of metal.

In the above-described method of manufacturing the paper product A, a colored engraving A3 is recessed by interposing a coloring material such as a ribbon between the corroding plate 1 and the base paper P (not shown). Alternatively, the stamp A3 may be colored using, for example, hot stamping, offset printing, UV printing, or the like.

FIG. 4 shows another embodiment of the present invention. This product is used without folding the paper product A in the unfolded state. Further, the configuration using a plain paper cardboard as the base paper P is shown in FIGS.
Unlike the embodiment shown in FIG. 3, the other configuration is the same as the embodiment shown in FIGS.

Although not shown, the punching template used in the method of manufacturing the paper product A is provided only with a cutting blade for the contour line A1, and there is no need to provide a pressing rule for a folding line. Further, in the case of the illustrated example, the paper product A is covered with a cup, and only the figure engraving A3 is recessed in the paper product A. However, the present invention is not limited to this, and it is not limited to this. It may be recessed.

Therefore, in the case shown in FIG. 4, since the base paper P is a corrugated cardboard, the corrugated paper P1 constituting the intermediate layer thereof is crushed by the corroded plate, and these are embossed on the entire bottom surface of the inscription A3 to form a stripe pattern. There is an advantage that the decorative effect is further improved.

In the above-described embodiment, the case where the paper product A is used without being folded, for example, in the unfolded state such as a box-mounting paperboard constituting a box or a carton or a cup-laying, for example, has been described. However, the present invention is not limited to this, and any other paper product may be used as long as it is a paper product produced by punching with the extraction blade A1.

Further, the case where the base paper P used in the method of manufacturing the paper product A is a cardboard or a corrugated cardboard is shown, but the present invention is not limited to this. Any other sheet material may be used as long as the stamp A3 such as a character or a figure by the pressing of the corroding plate 1 is hardly elastically restored. Still further, the base paper P is not limited to a plain paper having a front surface, and the base paper P having a front surface printed in advance by the above-described manufacturing method.
The erosion plate 1 may be pressed to form a mark A3 such as a character or a figure.

[0027]

As described above, according to the first, second and third aspects of the present invention, at the same time as the cutting of the contour line by the cutting blade, the corroded plate is pressed to mark the characters and figures. By forming the recess, the stamping and engraving are performed at once, so that the paper product with the engraving can be easily provided in the shortest time.
Therefore, compared to conventional paper products that display characters and graphics by printing, they are more likely to remain in the customer's impression, and because they do not use ink, they do not cause environmental pollution and are easier to recycle. The effect that the product image and the corporate image of the provider of the product become natural and give a good feeling can be obtained. Furthermore, in comparison with the conventional paper product production method of punching out base paper on which characters and graphics have already been displayed by printing, the stamping machine and other press machines simply press the die on the base paper to display characters and graphics. And the punching process can be performed at the same time, so that no labor is required, the production time of the paper product can be shortened, and the production cost can be greatly reduced. In addition, compared to a die where the part corresponding to the stamp and the punching blade are integrally formed by corrosion, only the part corresponding to the stamp needs to be partially formed by corrosion. is there.

According to a fourth aspect of the present invention, in addition to the effect of the third aspect of the present invention, the pressing force against the base paper from a press machine such as a punching machine is evenly transmitted to the entire surface of the corroded plate via a metal table. The entire stamp can be clearly displayed without making the entire template with metal. Therefore, inexpensive plywood, plastic, or the like can be used as the material of the template, and the template can be manufactured at a lower cost than when the entire template is made of metal.
