DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign maker using a pre-applying tool, such as a cutting plotter for cutting a cutting sheet or pattern into a desired shape, an engraving machine for engraving characters or figures on a name plate or a nameplate. The present invention relates to a blade tip projection amount adjusting mechanism of a first-aid tool for adjusting the cutting or cutting depth of a processing material such as a cutting sheet, a pattern, a name plate or a nameplate.

[0002]

2. Description of the Related Art Conventionally, as a sign maker using a pre-applying tool, as shown in FIG. 5, for example, a bed 1 on which a processing material is placed and a pre-applying tool 2 can freely contact the processing material. Sign maker provided with a tool holder 3 having an up-down function to make the tool holder move, a carriage 4 having the tool holder 3 movable in the Y-axis direction, and a Y rail 5 having the carriage 4 movable in the X-axis direction. There are six.

As shown in FIG. 6, the tool holder 3 has a flange portion 2a of the pre-applying tool 2 at a holder portion 3a.
By driving the solenoid 3b engaged with the holder portion 3a while holding the tool, the pre-applying tool 2 can be brought into contact with or separated from the work material 7.

[0004] As shown in FIG. 7, the tip contact tool 2 has a threaded portion 2 g formed on the outer periphery of a blade holder 2 d for rotatably holding a blade 2 c having a blade edge 2 b at a lower end thereof along a central axis. It is engraved. Further, a screw portion 2h is engraved on an inner periphery of a front contact portion 2f provided at the bottom with a protruding hole 2e through which the cutting edge 2b can advance and retreat. The threaded portions are screwed together to form the leading tool 2. Therefore, the amount of protrusion of the blade edge 2b can be adjusted by rotating the front contact portion 2f.

[0005] The sign maker 6 is a so-called cutting plotter for cutting a sheet-like processing material. In an engraving machine for cutting an engraving processing material, the cutting edge is formed in a V-shape. It is necessary to have a configuration for forcibly rotating the blade. However, in any case, there is no change in the basic configuration in which the cutting portion or the cutting depth is adjusted by manually rotating the front contact portion of the first contact tool and adjusting the protrusion amount of the cutting edge. Also, as a different type of pre-applying tool, a flange is formed on the pre-applied part, and there is a tool that adjusts the protruding amount of the blade by rotating the blade holder by hand, but this is also manually performed. You still have to adjust the volume.

[0006]

By the way, such a sign maker 6 stops the operation of the apparatus once every time the cutting or the cutting depth is changed, and manually moves the pre-applying portion 2f of the pre-applying tool 2. To adjust the protruding amount of the blade edge. In particular, when using a multi-colored multi-layer cutting sheet or multi-colored laminated plate to express colorful figures or characters, or to express engraved lines with different thicknesses due to differences in cutting depth, the cutting or cutting depth Since the change of the cutting edge is frequently performed, the number of times of adjusting the amount of protrusion of the blade edge is increased, and the processing of the material takes much time. In addition, since the adjustment of the blade tip protrusion amount must be performed by a person, a person must always be present near the apparatus.

[0007] The adjustment of the protruding amount of the cutting edge is performed either by removing the pre-applied tool 2 from the tool holder 3 or while holding the tool in the tool holder 3. If the pre-applying tool 2 is detached from the tool holder 3 each time, there is a problem that the working time increases. In order to adjust the amount of protrusion of the cutting edge while holding the contact tool 2 in the tool holder 3, the line of sight must be horizontal to the bed, and the contact portion 2f is manually rotated. When doing so, there is a problem that workability is poor, for example, the tool holder 3, the carriage 4, and the Y rail 5 are in the way.

Further, since the adjustment of the blade tip protrusion amount is performed by manually rotating the front contact portion 2f of the front contact tool 2, it is difficult to accurately adjust the blade tip protrusion amount. And it is difficult to obtain an accurate cutting or cutting depth.

Furthermore, when rotating the contact portion 2f by hand, there is a risk that the hand may touch the blade edge 2b and cause injury.

[0010] The present invention has been made in view of such circumstances, and a purpose thereof is to automatically and accurately and safely control the amount of protrusion of a blade of a pre-applied tool when necessary. An object of the present invention is to provide a mechanism for adjusting the amount of protrusion of a front end tool of a sign maker, which adjusts the amount of protrusion of a blade.

[0011]

SUMMARY OF THE INVENTION According to the present invention, there is provided a blade holder which holds a blade having a cutting edge formed at a lower end portion rotatably along a central axis. A pinion gear is fixedly mounted on an outer periphery of the blade holder or an outer periphery of the abutment portion in an abutment tool formed by screwing an abutment portion having a bottom formed with a protruding hole at the bottom portion. In addition, a rack rail meshable with the pinion gear is provided within the movement range of the leading tool.
Further, in a state where the pinion gear is meshed with the rack rail, the tip contact tool is relatively moved along the rack rail, so that the pinion gear is rotated by the rack rail to adjust the blade tip protrusion amount. The control unit is provided.

According to this means, when it is desired to change the cutting or the cutting depth of the work material, the pinion gear is first engaged with the rack rail while holding the contact tool in the tool tool holder. By moving the contact tool relatively and further along the rack rail in that state, the blade holder or the leading contact portion is rotated. At this time, the protruding amount of the cutting edge from the protruding hole is adjusted according to the moving amount of the pre-applying tool.
