Abstract

PURPOSE:To engrave a large number of seals and other sealing materials precisely at a time by replacing the movement of a profiling section, to which a detector profiling a sample on a master plate is mounted, with an electric signal and driving and controlling a driving table to which the sealing material is set. CONSTITUTION:Printing materials are set to each chuck for a driving table first, and a cutter is held on the driving table at regular intervals so as to correspond to a large number of the chucks on the upper surface of the driving table. A scaled-up sample is placed on a master plate for a profiling section under the state, and a skilled labor profiles the shape of the scaled-up sample by operating a detector such as a manual pen. The movement of the detector is replaced with an electric signal. The driving table to which the sealing materials are set operates an X-axis motor, a Y-axis motor and a Z-axis motor by the electric signal, and is driven in the horizontal and vertical directions. The sealing materials on the driving table are shifted so as to reproduce profiling operation by driving the driving table, and the surfaces of sealing are engraved accurately by a cutter.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a new seal engraving machine,
``It is an object of the present invention to provide a seal engraving machine that can engrave a material to be engraved, such as a seal, by making use of the engraving skills of the operator.

[Conventional technology]

Conventionally, as a means of mass-producing seals that are allowed to have similar seal surfaces, such as ceremonial seals, seals have been formed from plastic by injection molding. It is undesirable that stamps with exactly the same stamp surface are molded, and it cannot be applied to stamp materials made of wooden materials.

[Problems to be solved by the invention] ゛Therefore, in recent years, many cutters have been used to engrave many seals,
I! A seal engraving machine that can produce stamps has now been developed. However, such seal engraving and engraving machines use a system in which the movement of the indicator rod is transmitted to the cutter using a pantograph.

That is, the movement of the cutter is performed by mechanically transmitting the movement of an indicator rod that moves over the sample to the cutter via a pantograph. On the other hand, the area of the stamp surface is small and requires accurate positioning when operating the cutter.
Ru. When a stamp engraving machine as described above is applied to such a stamp surface, the cutting resistance increases rapidly as the number of stamps increases, making it extremely difficult to increase the number of stamps that can be engraved at one time.

[Means for solving problems]

The seal engraving machine of this invention was developed in consideration of these circumstances.

This eliminates the above-mentioned drawbacks of the conventional example by making it possible to accurately engrave a large number of stamps and other stamp materials at once. That is, a tracing section equipped with a detector for tracing the sample on the master plate, a means for converting the movement of the tracing section into an electric signal, a driving table on which the stamp material is set, and a drive control of the driving table from the electric signal number. This is a seal engraving machine characterized by having means for engraving the surface of a stamp material set on a drive table.

[Embodiment] An embodiment of the seal engraving machine of the present invention will be described below based on the drawings.

In this invention, the tracing section includes a master plate provided on which an enlarged sample can be placed at a location separate from the drive table on which the stamp material is set, and a detector provided on the master plate. A detector consisting of a manual pen or the like is supported so as to hang from a post erected adjacent to the master plate. The movement of the tracing section is converted into an electrical signal by a means such as a linear scale or an encoder that converts the movement of the tracing section into an electrical signal.

In other words, the movement of the manual pen in the X, Y, and Z axis directions is reduced to actual size with a pantograph, etc., and the movement is read on the X scale, Y scale, and Z scale, which measure in each direction of XY2, and the tracing section described above is measured. It replaces movement with electrical signals.

The drive table on which the stamp material is set is driven by operating the X-axis motor, Y-axis motor, and two-axis motor in response to the electric signal. The means for driving and controlling the drive table is a positioner and a servo amplifier.

It is composed of the above-mentioned X-axis motor, Y-axis motor, and two-axis motor. The above-mentioned command pulse as an electric signal is input to a positioner, and while the position is controlled by this positioner, it is amplified and outputted by a servo amplifier.

Drives the X-axis motor, Y-axis motor 2, and z-axis motor. X
A feedback unit connected to the axis motor, Y-axis motor, and two-axis motor re-inputs current position information of the drive table to the positioner as a feedback pulse.

The CPU connected to each scale and positioner surface has the function of returning the profiling section and drive table to their origin and controlling their positions, ensuring accurate engraving over a long period of time. Furthermore, by attaching a memory to this CPU (in that case, it is necessary to connect the CPU to each scale and each body), it is possible to automate the engraving work.

A large number of chucks are built into the upper surface of the driving table, and the driving table is driven with the stamp material set on the chucks. In conventional seal engraving machines, the drive table was fixed and the cutter was driven, but in this invention, the drive table is driven, which simplifies the drive control of the entire device and increases accuracy. It is possible to make beautiful carvings.

The means for engraving the stamp surface of the stamp material set on the drive table includes holding cutters at predetermined intervals on the drive table in advance;
This corresponds to a large number of chucks on the top surface of the drive table. I! The material to be engraved, such as a stamp material set on the drive table, can be engraved to a predetermined depth by driving the drive table with the stamp material set on the drive table and raising the drive table in the Z-axis direction. can.

[Effect]

The operation of the seal engraving machine of this invention will be explained.

First, a stamp material is set on each chuck on the drive table, and cutters are held on the drive table at predetermined intervals so as to correspond to a large number of chucks on the top surface of the drive table. In this state, the enlarged sample is placed on a master plate provided with a part number, which is separate from the drive table. A skilled person operates a detector such as a manual pen and traces the shape of the enlarged sample. This movement is translated into an electrical signal by means such as a linear scale.

The drive table on which the stamp material is set is driven in the horizontal and vertical directions by operating the X-axis motor, Y-axis motor, and Z-axis motor in response to the electric signal.

By driving the drive table, the stamp material on the drive table moves as if reproducing the tracing operation described above.

The cutter accurately engraves the stamp surface.

If a memory such as a magnetic disk is attached to the means for driving and controlling the drive table, the engraving technique of the above-mentioned expert can be easily reused by retrieving this memory as needed.

It is preferable that the drive table moves under the cutter in a sliding manner, and by using a plurality of drive tables, it is possible to eliminate the idle time required for attaching and removing the stamp material to the chuck.

〔Effect of the invention〕

Since the seal engraving machine of the present invention is configured as described above, it is possible to accurately reproduce the movement on the sample. Moreover, even if the number of stamps increases and the cutting resistance increases, the five-drive table is driven in a system separate from the movement of the detector, so the number of stamps that can be engraved at one time can be greatly increased.

In addition, the structure is simple and easy to operate, making it possible to automate the process to a large extent.
