Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can provide an appropriate engraving depth and can be easily engraved without requiring an auxiliary jig, an interval adjusting mechanism, a cutter edge sensor and its control circuit.
The present invention relates to a stamp material, particularly a stamp engraving method and a stamp engraving machine.

[0002]

2. Description of the Related Art Conventionally, with the development of the electronic control field,
Various automatic stamp engraving machines have been put to practical use.
Some of them apply laser processing or the like capable of non-contact processing, but they have a disadvantage that they are expensive.

[0003] In the case of a stamp engraving machine by cutting using a cutter, a work such as a stamping material to be processed is fixed,
Alternatively, the cutter is moved in the X-axis and Y-axis directions, while the cutter is rotated while sliding on the vertical axis in the Z-axis direction, thereby engraving characters, figures and patterns on the work stamp surface in three dimensions. . In this case, engraving on a plane can be easily performed by causing the control unit to store and calculate the diameter and area of the work such as a stamping material and the distance from the mechanical origin of the stamping material holding mechanism.

[0004] However, in order to realize the depth to be engraved with the calculated width, complicated mechanisms and auxiliary jigs have been required. Because the length of the stamp material is not constant, the depth to be engraved may change and adjustment work may be required.In addition, the cutter may be removed from the cutter holding mechanism due to wear or breakage of the cutter, and polishing may be performed. It is necessary to change the length of the cutter, but the length of the cutter changes during re-insertion, so that an adjustment work is indispensable.

For example, since the length of the stamping material is not constant, the engraving surface of the stamping material is brought into contact with the engraving reference surface of the stamping material holding mechanism. Although there is an auxiliary jig for pulling out and positioning the printing surface of the printing material inserted into the mechanism, the adjustment requires a considerable amount of time and skill, and has a problem that an error occurs.

When the length of the cutter changes, the tip of the cutter, which is covered by the cutter holding mechanism and inserted into the cutter holding mechanism to its inner end face, is pulled out so that the cutter can be pulled out to the engraving reference surface of the cutter holding mechanism. Although there is an auxiliary jig for positioning by adjusting the position, there is a problem that the adjustment requires a considerable amount of time and skill, and an error occurs.

[0007] Alternatively, there is an interval adjusting mechanism in which an adjusting screw is provided in the cutter holding mechanism or the printing material holding mechanism to adjust the distance between the printing surface of the printing material and the cutting edge of the cutter. Furthermore, there is a method of detecting the blade edge of the cutter using a sensor and adjusting the distance between the stamp surface of the stamping material and the blade edge of the cutter. However, all of these methods have a complicated structure and are expensive. was there.

[0008]

According to the present invention, an appropriate engraving depth can be obtained without using these auxiliary jigs, a gap adjusting mechanism, a sensor and a control circuit therefor, and a stamp material having a special size can be obtained. It is an object of the present invention to provide a stamp engraving method and a stamp engraving machine which can be easily engraved and inexpensive, and can be used.

[0009]

The present inventor has made intensive studies to solve the above-mentioned problems, and as a result, basically, a cutter holding mechanism automatically controlled to slide in the Z-axis direction, an X-axis and a It consists of a printing material holding mechanism that is automatically controlled to move in the Y-axis direction. The cutter holding mechanism and the printing material holding mechanism are preliminarily controlled by a control circuit. The relative movement is automatically made to the calculated position, and the stamp material is inserted into the stamp material holding mechanism, and the stamp material is held and fixed with the blade edge of the cutter lightly abutting on the engraved surface. Invention of a means for engraving a stamp material by retreating once by a predetermined width in the Z-axis direction and then feeding the cutter to the stamp material side to a distance calculated by the control circuit. It was.

The Z-axis direction of the cutter holding mechanism and the insertion direction of the stamp material of the stamp material holding mechanism are both horizontal, so that the manual insertion of the stamp material and the abutment of the cutter against the cutting edge are facilitated. Is preferable.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a stamp engraving machine according to an embodiment of the present invention. It should be noted that the technical scope of the present invention is not limited to the words described in the claims, but also extends to equivalent ranges having replaceability and ease of replacement. FIG. 1 is a perspective view showing an embodiment of a stamp engraving machine according to the present invention, and FIG. 2 is a schematic front view illustrating an embodiment of the present invention.

As shown in FIG. 1, a cutter holding mechanism 2, which is automatically controlled so as to protrude from the apparatus main body 1 and slide in the Z-axis direction, holds an appropriately positioned cutter 3 at its end, and rotates as a whole. Exists.

The cutter 3 inserted and held at the end of the cutter holding mechanism 2 is fixed by screws 12 in FIG. Although the fixing method is not limited, since the cutter 2 rotates at a high speed, it is necessary to prevent the cutter 2 from easily loosening or detaching from the cutter holding mechanism 2. The length of the cutter 3 established from the end of the cutter holding mechanism 2 is not particularly limited. The cutter 3 itself has a shape and strength suitable for engraving the stamp material 10. The cutter holding mechanism 2 slides in the direction of the arrow Z in FIG. 1, and the sliding width is controlled by a computer program stored in the apparatus main body 1. As described above, the cutter holding mechanism 2 slides in the Z-axis direction, and the stamp material holding mechanism 5 slides in the X-axis and Y-axis directions. These X-axis, Y-axis, and Z-axis expressions are used. Is a relative concept for three-dimensional engraving, so that the cutter holding mechanism 2 is
This does not exclude the case where the robot has a function of moving the axis.

Next, as shown in FIG. 1, the apparatus body 1 is automatically controlled to move in the X-axis and Y-axis directions via a holding shaft 5 and has a U-shape. A receiving groove 9 is provided.
There is a printing material holding mechanism 5 provided with a pressing portion 6 for holding and fixing the printing material.

The structure of the stamp holding mechanism 5 is not particularly limited. In the embodiment, as described above, the stamp material 10 is sandwiched from above and below. However, a method of sandwiching the stamp material 10 from left and right, a method of fitting it into a cylindrical member and fixing it with screws or the like can be considered. Also,
It is assumed that the sheet is manually sandwiched between the stamp holding mechanisms 5 in the direction of arrow B shown in FIG. By the way, in the present invention, the stamp engraving method and the stamp engraving machine are also adopted as the title of the invention, but it is natural that the object to be engraved can be applied to other than the stamp material, for example, In the case of a flat plate, it has a structure of a holding mechanism capable of holding it.

Incidentally, the Z-axis direction of the cutter holding mechanism 2 and
The direction in which the stamping material 10 is inserted into the stamping material holding mechanism 5 must be parallel in relation to the engraving work. However, in order to facilitate the manual insertion of the stamping material 10 and the abutment of the cutter 3 with the blade edge, It is preferable that the horizontal direction also be formed. However, it may be in a vertical state or an inclined state.

In the apparatus body 1, the data to be engraved on the object to be engraved, the cutter holding mechanism 2 and the printing material holding mechanism 5 are automatically and relatively moved to positions calculated by a control circuit in advance. After holding the stamping material 10 in a state where the cutter 3 is lightly abutted on the engraving surface of the stamping material 10, the cutter 3 is first retracted once in the Z-axis direction by a predetermined width α at the start of engraving. Let
The control circuit has a built-in data for sending the cutter 3 to the printing material 10 to the calculated distance thereafter. The object to be engraved is intended for a stamp material, but is not limited to a character but may be a figure or a pattern. Although the present invention is applied to a seal, it can be applied to other objects to be engraved as described above.

First, with the cutter 3 held at the end of the cutter holding mechanism 2, the cutter holding mechanism 2 and the printing material holding mechanism 5 are relatively moved to a position calculated by a control circuit in advance. However, there is no limitation on the moving direction. As shown in FIG. 2, it moves in the direction of arrow A from the position represented by the dashed line. In this case, the movement of only the cutter holding mechanism 2, the movement of only the printing material holding mechanism 5, or the movement of both at the same time may be used. The cutting edge of the cutter 3 is near the center of the stamp surface of the stamp material to be fitted into the stamp material holding mechanism 5. However, depending on the engraved character, the engraved figure, or the like, as long as it is the stamped surface portion of the stamp material, it is not limited to the center portion, and may be near the outer peripheral surface.

Next, the stamping material 10 is transferred to the receiving stand 8 of the stamping material holding mechanism 5.
And pressing the opposite side of the printing surface of the printing material 10 with fingers or the like moves the printing material 10 rightward in FIG. Then, the cutter is lightly brought into contact with the cutting edge of the cutter 3, positioned at the contact point 11, and the pressing portion 6 is lowered by the adjusting screw 7 to be held by the printing material holding mechanism 5. This operation can be performed without skill. In this state, the positioning of the cutter 3 and the printing material 10 is completed, and the engraving preparation operation is completed.

At the start of the engraving operation, the cutter 3 is first retracted in the Z-axis direction. The receding width is a preset width, which is indicated by α in FIG. 2, but is not limited thereto. In short, if the cutter 3 is moved in the X-axis or Y-axis direction and the engraving operation is started while the cutting edge of the cutter 3 is in contact with the imprint surface of the imprint material 10, the engraving operation will fail due to scratching the imprint surface. There is a possibility that the width may be reduced. Then, after that, the cutter 3 is sent to the printing material 10 to the distance calculated by the control circuit, and three-dimensional engraving is performed on the object to be engraved in accordance with the input data to be engraved.

When the object to be engraved is a fixed form such as a character, a personal name code, a typeface, a size, etc. are determined in advance, and if necessary information is input, a program capable of engraving according to the information is installed. The engraving can be performed only by inputting numbers to the control panel 13 or the like.

[0022]

As is apparent from the above description, in the stamp engraving method and the stamp engraving machine according to the present invention, the cutter 3 is held at the end of the cutter holding mechanism 2.
The cutter holding mechanism 2 and the printing material holding mechanism 5 are relatively moved to a position calculated by a control circuit in advance, and the printing material 10 is placed on the receiving table 8 of the printing material holding mechanism 5 and lightly abuts against the cutting edge of the cutter 3 to be fixed. As a result, the position becomes the reference surface of the engraving depth at the time of engraving work, so that the appropriate engraving depth can be obtained regardless of the length of the cutter or the length of the stamping material, etc. Not only that, there is no need for a conventional auxiliary jig, interval adjusting mechanism, sensor and its control circuit, etc., and it is possible to provide an easily engravable and inexpensive stamp engraving method and a stamp engraving machine. It exerts an objective effect.
