Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a plotter for making various drawings on a paper surface on a top plate and for making sewing patterns by a pen that is automatically driven in the X and Y directions. The present invention relates to a device having both a function and a laser cutter function of cutting a sheet-shaped or thin-plate-shaped work on a top plate by a laser beam emitted from a laser nozzle driven similarly to the pen.

(Prior Art) As a plotter device that automatically performs drawing for various drawings and sewing pattern making, an X-direction moving bar that moves in one side direction of the top plate, that is, in the X direction while straddling the top plate. A Y-direction moving body that is movable in the longitudinal direction, that is, the Y direction, is fitted so that the plotter pen attached to the moving body can be set to any position on the top plate according to the positional relationship between the moving bar and the moving body. There is something I did. That is, in such a plotter device, by driving and controlling the moving bar and the moving body by a predetermined program software to move the plotter pen, it is possible to automatically and freely draw on the paper surface arranged on the top plate. . Also, the above Y
In some cases, a plotter pen and a special cutter knife can be attached to and detached from the directional moving body so that the paper sheet can be cut along with drawing.

(Problems to be solved by the invention) However, although the plotter device has a wide top plate and occupies a very large space, it can normally be used only for drawing, and even when a cutter knife is used. The object to be cut is limited to paper of a specific paper quality, and the shape of the cutting line is limited because the paper must be held immovably on the top plate, so that there is a problem that it is not possible to freely cut as in drawing. Therefore, when it is necessary to perform a cutter operation for cutting a flat material such as a sheet of paper, a chemical sheet, a cloth, a leather or a thin metal plate into a predetermined shape in association with the plotter operation depending on the type of business, it is as large as the plotter device. There is a problem that a space-saving cutter device must be installed together, the work space becomes narrow, the space utilization rate deteriorates, and the facility cost becomes very high.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an apparatus having both a plotter function and a laser cutter function, thereby making it possible to improve the space utilization rate and significantly reduce the equipment cost.

(Means for Solving the Problems) As a means for achieving the above object, a plotter device with a laser cutter according to the present invention has a table base provided with a rectangular top plate portion made of a metal honeycomb board that penetrates in a thickness direction. , A pair of guide rails along both opposite edges of the top plate portion, and a sheet-shaped or thin plate-shaped work placed on the honeycomb board is sucked and held in a fixed position by suction from the lower surface side of the honeycomb board. A suction means is provided, and X-direction moving bars that straddle and separate from the top plate are slidably supported by both guide rails at both ends thereof, and the laser nozzle mounting portion and plotter are attached to the X-direction moving bars. A Y-direction moving body having a pen mounting portion is slidably fitted along the longitudinal direction of the X-direction moving bar, and is further detachably mounted on the top plate portion. A configuration including a plate-like plotter board, a laser oscillator for supplying a laser beam to a laser nozzle of a Y-direction moving body through an optical system, and a driving means for the X-direction moving bar and the Y-direction moving body is adopted. To do.

(Operation) Since the X-direction moving bar is movable along the guide rails on both sides of the top plate, and the Y-direction moving body is fitted on the moving bar so as to be movable along the longitudinal direction of the moving bar. , Y
The plotter pen and the laser nozzle attached to the directional moving body can be set at arbitrary positions on the top plate. That is, X
The X coordinate is determined by the direction moving bar, and the Y coordinate is determined by the Y direction moving body. Therefore, by relatively adjusting the moving speeds of the moving bar and the moving body by controlling the respective driving means, the writing point by the plotter pen and the irradiation point of the laser beam by the laser nozzle can be adjusted to straight lines in various directions and various points. It is possible to move so as to draw a curve, and the starting and ending points of these straight lines and curves can be arbitrarily determined.

For plotting with a plotter pen, place a plotter board on the top plate, arrange a sheet of paper or the like to be plotted on the board, and move the moving bar and the moving body according to the program software as in the conventional plotter device. Just drive it.

On the other hand, in order to perform cutting with a laser nozzle, remove the plotter board, place paper, chemical sheet, leather, cloth, and flat work to be cut on a thin metal plate on the honeycomb board, and suck these works. It may be adsorbed and fixed on the honeycomb board by means, and the laser oscillator may be operated to drive the moving bar and the moving body as in the plotter. Note that the program software for the plotter can be used for this cutting as it is. Then,
As the laser oscillator, various types such as a fixed laser, a gas laser, a liquid laser, and a semiconductor laser can be used, and the laser type and output may be selected according to the material and thickness of the workpiece. The honeycomb board can be produced by cutting a metal extruded mold material such as aluminum perpendicular to the extrusion direction, so high flatness can be secured, and due to the high reflectivity peculiar to the metal, the laser beam at the time of cutting processing can be highly efficient. Since it reflects, the board itself is not invaded.
