DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embossed pattern engraving apparatus for embossing a so-called embossed pattern on a sheet-shaped object.

[0002]

2. Description of the Related Art An embossed pattern engraving apparatus of this type is disclosed in Japanese Patent Application Laid-Open Nos. 6-305294 and 6-79814. In the embossed pattern engraving device disclosed in these prior art documents, a stamped female die, a sheet-shaped engraved object such as a paper leaf is inserted between the engraved male die, and then the engraved female die and the engraved male die. During this time, a pressing force is applied to transfer the engraved marks applied to both molds to the sheet-shaped engraved object. The pressing force for engraving can be obtained by operating a lever provided on one of the engraved male type and engraved female type.

According to the conventional embossed pattern engraving,
Only one embossed pattern can be obtained by one engraving operation. When a plurality of embossed patterns are to be provided on the same sheet-shaped engraved object, the positions of the sheet-shaped engraved object with respect to the engraved female die and the engraved male die are changed by manual operation, and then the stamping for engraving is performed. It is necessary to repeat the operation of applying pressure. For this reason, it is not suitable for continuously embossing a large number of embossed patterns at the same pitch interval.

Further, since the pressing force for engraving is obtained by operating the lever, it is necessary to apply a large force to the lever.
It becomes difficult to imprint a clear embossed pattern. This problem becomes more prominent as the area of the raised pattern increases.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an embossing pattern marking device suitable for successively marking a number of embossing patterns at the same pitch.

Another object of the present invention is to provide an embossed pattern engraving apparatus which can easily emboss an embossed pattern having a clear contour even for a weak woman, child or the like.

Still another object of the present invention is to provide an embossed pattern marking device capable of marking an embossed pattern having a clear contour without being influenced by the effective area of the embossed pattern.

[0008]

In order to solve the above-mentioned problems, an embossed pattern engraving apparatus according to the present invention is used for embossing an embossed pattern on a sheet-shaped object to be embossed. , Receiving part. The rolling roller has an embossed pattern engraving die on a circular outer peripheral surface, or has a mounting portion for attaching the embossed pattern engraving die. The rolling roller has a rotating shaft supported at a fixed position, and is rotated by a rotational driving force applied from the outside. The receiving portion is opposed to the outer peripheral surface of the pressure roller, and the opposed surface is a flat surface, a convex surface, or a concave surface having a radius larger than the radius of the pressure roller, and has a sheet-like shape with the outer peripheral surface. An interval for inserting the object to be stamped is formed.

As described above, the receiving portion is opposed to the outer peripheral surface of the pressure roller, and the opposed surface forms a gap between the roller and the pressure roller for inserting a sheet-shaped object to be stamped. The sheet-shaped engraved object can be inserted between the roller and the facing surface of the receiving portion.

The pressure roller has a circular outer peripheral surface, and the receiving portion has a flat surface, a convex surface, or a concave surface having a radius larger than the radius of the pressure roller. A linear rolling pressure along the axial direction of the outer peripheral surface of the pressure roller can be applied to the sheet-shaped object to be stamped inserted between the roller and the roller. This linear rolling pressure is substantially constant without being affected by the size of the effective area of the raised pattern. Therefore, an embossed pattern having a clear contour can be stamped without being affected by the size of the effective area of the embossed pattern.

[0011] Since the rotating shaft of the pressure roller is supported at a fixed position and is rotated by an externally applied rotational driving force, a line along the axial direction of the outer peripheral surface of the pressure roller is formed on the sheet-shaped engraved object. In the state where the state rolling pressure is applied, the rolling roller can be rotated around the shaft to feed the sheet-shaped object to be marked. At the time of the engraving operation, it is only necessary to give the rolling roller a shaft rotation. For this reason, unlike the prior art in which a pressing load is applied by a lever, the force required for engraving is significantly reduced, and even a weak woman, child, etc. can easily create an embossed pattern with a clear contour. Can be engraved.

The rolling roller has an embossed pattern engraving die on the outer peripheral surface of the circular shape or has a mounting portion for mounting the embossed pattern engraving die. A large number of embossed patterns can be continuously imprinted at the same pitch interval.

The embossed pattern engraving device according to the present invention is not limited to a case in which an embossed pattern due to the surface irregularities of the sheet itself is provided on the sheet, and a metal foil pattern or the like is formed on the sheet or other sheet-shaped engraved objects. It can also be applied to so-called foil stamping technology.

Other objects, configurations and effects of the present invention will be described in more detail with reference to the accompanying drawings as embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view showing the configuration of an embossed pattern marking device according to the present invention. The embossing pattern marking device according to the present invention is used for marking an embossing pattern on a sheet-shaped to-be-marked object X.
And a receiving part 2. The roller 1 has an embossed pattern engraving die 31 on a circular outer peripheral surface. The embossed pattern engraving die 31 may be formed directly on the outer peripheral surface of the pressure roller 1 or a mounting portion for attaching the embossed pattern engraving die 31 on the outer peripheral surface of the pressure roller 1 may be provided. By utilizing, a structure in which an embossed pattern engraving die 31 which is a separate member from the pressure roller 1 may be attached. FIG. 2 is a cross-sectional view of an embossed pattern stamping die 31 prepared as a separate part, and has an embossed pattern 311 on the surface. The embossed pattern 311 is formed according to the pattern to be obtained. The embossed pattern engraving die 31 can be formed using an arbitrary material such as plastic or metal. The rolling roller 1 is supported by the rotating shaft 101 at a fixed position, and is rotated by an externally applied rotational driving force as shown by an arrow a1.

The receiving portion 2 is opposed to the outer peripheral surface of the pressure roller 1 and has a flat or convex surface facing the outer peripheral surface of the pressure roller 1. Has formed.

As described above, the receiving portion 2 is provided with the pressure roller 1.
Of the pressure roller 1, and the facing surface forms an interval 4 for inserting the sheet-shaped engraved object X between the outer surface of the roller 1 and the outer surface of the roller 1. The sheet-shaped engraved object X can be inserted between the opposed surface of the portion 2.

Since the pressure roller 1 has a circular outer peripheral surface and the receiving portion 2 has a flat or convex facing surface, the receiving portion 2 is located between the facing surface of the receiving portion 2 and the outer peripheral surface of the pressure roller 1. In the above, a linear rolling pressure F1 along the axial direction of the outer peripheral surface of the pressure roller 1 can be applied to the sheet-shaped to-be-marked object X. The linear rolling pressure F1 is substantially constant without being affected by the size of the effective area of the embossed pattern 311. For this reason, an embossed pattern having a clear contour can be imprinted on the sheet-shaped to-be-marked object X without depending on the effective area of the embossed pattern 311.

Since the rotary shaft 101 is supported at a fixed position and is rotated by an externally applied rotational driving force, the roller 1 is attached to the sheet-shaped stamped object X.
With a linear rolling pressure F1 along the axial direction of the outer peripheral surface of
By rotating the roller 1 in the direction of the arrow a1, the sheet-shaped engraved object X can be fed. In performing the engraving operation, it is only necessary to give the roller 1 a shaft rotation. For this reason, unlike the prior art in which a pressing load is applied by a lever, the force required for engraving is significantly reduced, and even a weak woman, child, etc. can easily create an embossed pattern with a clear contour. Can be engraved.

The pressure roller 1 has an embossed pattern engraving die 31 on the outer peripheral surface of a circular shape, or has a mounting portion for attaching the embossed pattern engraving die 31, so that it is provided on the outer peripheral surface of the pressure roller 1. With the embossed pattern marking die 31, a large number of embossed patterns 311 can be continuously stamped on the sheet-shaped to-be-marked object X at the same pitch interval. The number, pitch, and the like of the raised patterns 311 are determined according to the number of rotations of the pressure roller 1 and the number of raised patterns 311 in one rotation.

In the embodiment shown in FIG. 1, the receiving portion 2 is a rotating roller. The receiving portion 2 composed of the rotating roller follows the pressure roller 1 and rotates in the direction of arrow a2. Therefore, the engraved object X can be sent out smoothly in the direction of the arrow b1. The outer peripheral surface of the rotating roller constituting the receiving portion 2 is provided with an embossed pattern engraving die 32 that is paired with the embossed pattern engraving die 31 provided on the pressure roller 1. When the embossed pattern engraving die 31 is a male type, the embossed pattern engraving die 32
Is female. FIG. 3 shows such an embossed pattern engraving type 3.
2 shows an example.

In this case, it is necessary to select the diameter D2 of the rotating roller constituting the receiving portion 2 so as to be equal to the diameter D1 of the pressure roller 1. Thereby, the embossed pattern engraving die 31 can be surely matched with the embossed pattern engraving die 32 at a predetermined mold position. In addition, when such a configuration is adopted, a rotation synchronization mechanism is included, and the rotation of the rotation roller forming the receiving unit 2 is synchronized with the rotation of the pressure roller 1 by the rotation synchronization mechanism. By having such a synchronization mechanism, the embossed pattern engraving die 32 can be surely matched with the embossed pattern engraving die 31 at a predetermined mold position.

FIG. 1 shows a case where the receiving portion 2 is constituted by a rotating roller. However, as shown in FIG. 4, the receiving portion 2 may have a flat surface. Or Figure 5
As shown in (1), the opposing surface may be a concave surface having a radius larger than the radius of the pressure roller 1.

Next, more specific embodiments of the present invention will be described. 6 is a perspective view showing the internal structure of the embossed pattern engraving device according to the embodiment of the present invention in an easy-to-understand manner, FIG. 7 is another perspective view of the embossed pattern engraving device shown in FIG. 6, and FIG. 6 is a right side sectional view of the embossed pattern marking device shown in FIG. 6 and FIG. 7, and FIG. 9 is a right side sectional view seen at a position further inside than FIG. Rolling roller 1

Both ends are supported in fixed positions by a case 5 (see FIGS. 8 and 9). The rotating shaft 101 has a knob 108 at one end thereof, and a rotational driving force is manually applied to the knob 108 from the outside. As a result, the roller 1 is rotated in the direction of arrow a1.

The receiving section 2 is a rotating roller. The rotating roller constituting the receiving portion 2 has attachment portions 202 to 205 for attaching the embossed pattern engraving die 32 on the outer peripheral surface of the circular shape. Hereinafter, for the sake of simplicity, the receiving portion 2 will be described as having the same meaning as a rotating roller.

It can be superimposed on the part with the embossed pattern.

Further, a rotary roller control mechanism 7 is provided. The rotating roller control mechanism 7 controls the position of the rotating shaft of the rotating roller 2, thereby controlling the distance 4 between the pressure roller 1 and the rotating roller 2. The illustrated rotating roller control mechanism 7 includes:
It has arms 71, 72, eccentric cams 73, 74, a shaft 75, and a knob 76. The arms 71 and 72 are arranged at intervals on both sides in the axial direction of the rotating roller 2, and rotatably support the rotating shaft 201 of the rotating roller 2.
Windows 711 and 721 are provided on the upper portions of the arms 71 and 72.

The eccentric cams 72, 73 are arranged in the windows 711, 721 and are connected by a shaft 75. The shaft 75 is rotatably supported by the case 5. Knob 7
6 is rotated by the eccentric cams 72 and 73.
1, 72 move in the vertical direction Y1, Y2, whereby the distance 4 between the compacting roll 1 and the rotating roll 2 changes.

Further, a rotation position deviation prevention mechanism 8 is included. The rotation position deviation prevention mechanism 8 prevents the rotation position deviation of the rotation roller 2 with respect to the pressure roller 1. The rotational position deviation prevention mechanism 8 shown in the embodiment includes a ring-shaped gear 107 formed on one axial end surface of the pressure roller 1 and a rotating roller 2.
A ring-shaped gear 207 formed on one end surface in the axial direction of
One gear 81 meshing with the two ring gears 107 and 207 is included. When the rotating roller 2 is moved in the vertical directions Y1 and Y2 by the rotating roller 2 mechanism 7, the rotating roller 2 moves in the same position of the gear 81 in the vertical directions Y1 and Y2. Position shift is prevented.

Next, a method of using the embossed pattern marking device shown in FIGS. 6 to 9 will be described. When the eccentric cams 73 and 74 of the rotating roller control mechanism 7 are at the positions shown in FIGS. 6 to 9, the side of the eccentric cams 73 and 74 where the radius of rotation is large corresponds to the windows 711 and 721 provided on the arms 71 and 72. Located on the lower side. In this position, the arms 71 and 72 are pushed down, and the position of the rotating shaft 201 of the rotating roller 2 is set to the lowest position. In the rolling roller 1 and the rotating roller 2, a gear 106 and a gear 206 provided respectively are meshed with each other.

Next, from the state shown in FIGS.
Is rotated in the direction of the arrow C1 (or in the opposite direction), and the rotating shaft 75 is rotated in the same direction. When the eccentric cams 73 and 74 have large rotation radii, the windows 7 provided in the arms 71 and 72
Move to the upper side of 11,721. Since the position of the rotation shaft 75 is not changed, the arms 71 and 72 are pushed upward,
The position of the rotating shaft 201 of the rotating roller 2 supported by the arms 71 and 72 also moves upward by ΔY (see FIG. 11). As a result, as shown in FIGS. 10 and 11, the interval 4 between the pressure roller 1 and the rotating roller 2 is enlarged.

When the rotating roller 2 is moved in the upward direction Y1, the gear 206 provided on the rotating roller 2 is separated from the gear 106 provided on the pressure roller 1, but since the gear 206 provided on the rolling roller 1 includes the rotation position deviation prevention mechanism 8, it is included. In addition, the rotational position of the rotary roller 2 with respect to the pressure roller 1 does not shift. More specifically, the rotation roller 2 is controlled by the rotation roller control mechanism 7.
Moves in the upward direction Y1, the gear provided on the rotating roller 2 moves in the same direction of the gear 81 in the upward direction Y1, so that the rotational position of the rotating roller 2 with respect to the pressure roller 1 is prevented from shifting.

Next, as shown in FIG. 11, the embossed pattern engraving die 3 passes through the space 4 enlarged as described above.
1 and the embossed pattern engraving die 32 are inserted and wound around the outer peripheral surface of the pressure roller 1 and the outer peripheral surface of the rotating roller 2. FIG. 12 shows a state where the embossed pattern engraving die 31 and the embossed pattern engraving mold 32 are wound around the outer peripheral surface of the pressure roller 1 and the outer peripheral surface of the rotating roller 2.

Next, as shown in FIG.
And through the gap 4 formed between the rotating roller 2 and
The sheet-shaped engraved object X is inserted.

Next, the knob 76 (see FIGS. 6 and 7) provided in the rotary roller control mechanism 7 is rotated in the direction of the arrow C1 or in the reverse direction C2 to move the rotary roller 2 in the downward direction Y2. As a result, the state returns to the state illustrated in FIGS. 6 to 9, and a printing pressure for marking is applied to the sheet-shaped marking object X between the pressure roller 1 and the rotating roller 2. When the rotating roller 2 moves in the downward direction Y2, the rotating roller 2
Move in the same direction in the downward direction Y2,
, The rotational position of the rotating roller 2 is prevented from being shifted.

In this state, the knob 108 provided on the roller 1 is rotated in the direction of arrow a1. The rotation roller 2 follows the pressure roller 1 and rotates in the direction of arrow a2. As a result, the embossed patterns of the embossed pattern engraving dies 31 and 32 are engraved on the sheet-shaped engraved object X.

Here, since the pressure roller 1 has a circular outer peripheral surface and the receiving portion 2 has a convex surface, the opposing surface of the receiving portion 2 and the outer peripheral surface of the pressure roller 1 are different from each other. In between,
A linear rolling pressure F1 along the axial direction of the outer peripheral surface of the pressure roller 1 can be applied to the sheet-shaped stamped object X. The linear rolling pressure F1 is substantially constant without being affected by the size of the effective area of the embossed pattern 311. Therefore, an embossed pattern having a clear contour can be imprinted without depending on the size of the effective area of the embossed pattern 311.

Since the rotary shaft 101 is supported at a fixed position and is rotated by a rotational driving force applied from the outside, the roller 1 is attached to the sheet-shaped stamped object X.
With a linear rolling pressure F1 along the axial direction of the outer peripheral surface of
By rotating the roller 1 in the direction of the arrow a1, the sheet-shaped engraved object X can be fed. In performing the engraving operation, it is only necessary to give the roller 1 a shaft rotation. For this reason, unlike the prior art in which a pressing load is applied by a lever, the force required for engraving is significantly reduced, and even a weak woman, child, etc. can easily create an embossed pattern with a clear contour. Can be engraved.

Since the pressure roller 1 has an embossed pattern engraving die 31 on the outer peripheral surface of a circular shape, or has a mounting portion for attaching the embossed pattern engraving die 31, it is provided on the outer peripheral surface of the pressure roller 1. With the embossed pattern engraving die 31, a large number of embossed patterns can be imprinted continuously on the sheet-shaped engraved object X at the same pitch interval. The number and pitch of the raised patterns are determined according to the number of rotations of the pressure roller 1 and the number of raised patterns within one rotation.
