Abstract

(57) [Summary] [Purpose] To be able to easily perform pen pressure correction work for all cuts and half cuts. [Structure] The controller of the cutting plotter includes a writing pressure setting changing unit 52, and the setting writing pressure of the writing pressure setting changing unit 52 can be corrected by operating a switch of an input device such as the operation panel 28. The full-cut and half-cut writing pressures set by the writing pressure setting changing unit 52 are displayed on the display unit 56 of the operation panel 28. After the writing pressure setting changing unit 52 enters the writing pressure changing mode by operating the switch of the operation panel 28, the writing pressure of full cut and half cut is changed every time the writing pressure increasing switch of the operation panel 28 is pushed. Both are incremented by a predetermined value, for example 10 g. On the contrary, when the writing pressure down switch is pushed, the writing pressures of the full cut and the half cut are simultaneously reduced by a predetermined value, for example, 10 g.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutting plotter with a writing pressure correction function.

[0002]

[Prior art]

 In this type of cutting plotter, the required writing pressure, that is, the pressure of the cutting edge 6 against the sheet material 2 or the platen 4 is always constant, as shown in FIG. 3, depending on the wear state of the cutting edge and the thickness and rigidity of the sheet material. is not. Further, in the cutting operation, two types of cuts, that is, all cuts shown in FIG. 3A and half cuts shown in FIG. 3B are required. Therefore, when the writing pressure is corrected by the actual cutting result, it is necessary to simultaneously correct the two types of writing pressure, that is, full cut and half cut. There is also one that sets the writing pressure on the CAD (computer-aided drafting system) side, but in this case, if the CAD host computer and plotter are close and directly connected to each other, the writing pressure is corrected. Can be done easily. The cutting plotter is designed so that one cutter pen can perform all cutting and half cutting. In this case, mechanical pen pressure adjustment is performed.

[0003]

[Problems to be solved by the device]

 In the above conventional cutting plotter, the pen pressure is set / changed by the panel operation for each pen number, so even if the pen pressure of one cutter pen is changed, the pen pressure for all cuts and half cuts is changed at the same time. I couldn't. That is, it is necessary to change the writing pressure for the full-cutting cutter and the half-cutting cutter. Therefore, there is a problem that the writing pressure correction work is troublesome. Further, when the writing pressure is set on the CAD side, normally one plotter is shared by a plurality of CADs. Therefore, the CAD data is transferred to the personal computer and then transferred to the plotter controller. Therefore, if the writing pressure is to be changed due to a poor cutting result, the CAD data must be called again to change the writing pressure setting, which causes a problem that the working time, that is, the occupation time of the CAD becomes very long. Existed. Further, the mechanical writing pressure adjustment in the cutting plotter is troublesome and time-consuming. The present invention is intended to solve the above problems.

[0004]

[Means for solving problems]

 To achieve the above object, the present invention provides a data buffer for storing drawing data from CAD or the like, a data analysis unit for converting the drawing data stored in the data buffer into drawing data for a plotter, and the data analysis. The sorting buffer that sorts the drawing data analyzed by the section, the writing pressure setting change unit that sets the writing pressure data for the cutter lift drive device built in the head, and the sorting buffer and writing pressure setting change unit. The sheet member outputs a control signal for an XY driving device that drives the head relative to the cutting member in the XY axis directions based on the output data, and a writing pressure signal and a pen lifting signal for the cutter lifting / lowering driving device. And a CPU adapted to perform all-cut or half-cut processing. Connected to an input device such as a panel, and the switch signal of the input device corrects the full-cut writing pressure data and the half-cut writing pressure data set in the writing pressure setting change section at the same time by a predetermined value in the up and down directions. It was made to be done.

[0005]

[Action]

 Pen pressure change for all cuts The pen pressure for half cut can be changed at the same time by operating the panel.

[0006]

【Example】

 Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. A sheet drive type cutting plotter 10 grips the sheet member 2 on the platen 4 by a pinch roller mechanism 14 driven by an X motor 12.

The sheet member 2 is configured to be fed on the platen 4 in the front-rear direction (X axis) by rotation of a drive roller (not shown) of the pinch roller mechanism 14. A Y rail 16 is arranged on the platen 4, and both ends of the Y rail 16 are fixed to boxes 22 and 24 supported by legs 18 and 20, respectively. A controller 26 of the plotter 10 is installed in the box 24, and an operation panel 28 of the controller 26 is provided on the upper surface of the box 24.

A head 30 is movably attached to the Y rail 16. The holding portion provided on the head 30 holds the pen 34 and the cutter 32, and each holding portion is connected to a lifting drive device built in the head 30. The elevating / lowering device is composed of known moving coil devices, and the pressure (writing pressure) of the pen 34 or the cutter 32 on the platen 4 is determined by the amount of current to these moving coil devices.

The plurality of elevation drive devices constitute a head drive mechanism 36, and are connected to the CPU 38 of the controller 26 via a driver. The head 30 is linked to a Y motor 40, and the movement of the head 30 is controlled along the Y rail 16 by driving the Y motor 40. A disk drive 44 for a floppy disk 42 is mounted on the leg 20, and the drive 44 is connected to the controller 26. The controller 26 has a data buffer 48 for storing data from the CAD 46 or the floppy disk 42.

A data analysis unit 50 converts data stored in the data buffer 48 into data for plotter. Reference numeral 52 is a writing pressure setting changing unit for correcting writing pressure according to a signal from an input device such as the operation panel 28. The writing pressure setting changing unit 52 receives writing pressure setting data from the CAD 46 or the floppy disk 42, and the writing pressure data is displayed on the display unit 56 of the operation panel 28.

For example, the display unit 56 displays a full cut 80 g and a half cut 30 g. The writing pressure setting changing unit 52 may store the writing pressure patterns of all cuts and half cuts in advance and operate the switch 58 of the operation panel 28 to call out a desired writing pressure pattern. . The writing pressure pattern may be automatically selected according to the type of the sheet member 2, for example, the thickness.

When the writing pressure setting changing section 52 is set to the writing pressure changing mode by the operation panel 28, the setting writing pressure is changed by a signal from the writing pressure changing + -switch of the operation panel 28. Is configured. When the current writing pressure is set to, for example, 80 g for full cut and 30 g for half cut, each time the writing pressure change + switch is pressed, 10 g of writing pressure is added for both full cut and half cut. That is, when the writing pressure change + switch is pressed once, the writing pressure is 90 g for full cut and 40 g for half cut.

When the switch is pressed once more, the writing pressure becomes 100 g for the full cut and 50 g for the half cut. Conversely, when the writing pressure change-switch is pushed, the writing pressure for full cut and half cut is reduced by 10g. That is, when the writing pressure change-switch is pressed once, the writing pressure becomes 70 g for all cuts and 20 g for half cuts. Change the writing pressure once more-press the switch and the writing pressure will be 60g for full cut and 10g for half cut.

Reference numeral 54 is a sort buffer, which reads the data from the data analysis unit 50, and based on the read data, the CPU 38 drives and controls each driver of the X motor 12 and the Y motor 40, and The driver of the drive mechanism 36 is drive-controlled to perform predetermined drawing or cutting on the sheet member 2. The operation of the above controller will be described below with reference to the flowchart shown in FIG.

When the process moves to the writing pressure setting changing unit 52 in step 1, the CPU 38 determines in step 2 whether a writing pressure changing command is input to the writing pressure setting changing unit 52 from the operation panel 28. If there is a command for changing the writing pressure, the CPU 38 proceeds to step 3 and determines here whether all the cuts have been made.

This judgment is confirmed by the flag of each line segment data transferred from the host computer of the CAD 46 or the floppy disk 42. That is, if a flag for all cuts is set before or after the line segment data, all cuts are processed.

When an affirmative decision is made in step 3, the CPU 38 sets a specified writing pressure for all cuts in step 4, and the cutter 32 descends with this writing pressure. Further, the CPU 38 raises the cutter 32 in step 4.

By the up / down operation of the cutter 32, the movement of the sheet member 2 in the X-axis direction, and the movement of the head 30 in the Y-axis direction along the Y-rail 16, a predetermined total cutting process is performed on the sheet member 2. Done. When the CPU 38 makes a negative decision in step 3, it sets a specified writing pressure for half-cutting in step 5, and with this writing pressure, the cutter 32 is lowered and the cutter 32 is controlled to be raised.

Further, in step 7, the CPU 38 controls the movement of the sheet member 2 in the X-axis direction and also controls the movement of the head 30 in the Y-axis direction to perform a half cut on the sheet member 2. When it is confirmed in step 2 that there is no command for changing the writing pressure, the CPU 38 next determines in step 8 whether or not all cuts have been made. When the determination in step 8 is affirmative, the CPU 38 performs processing in step 9. When a negative determination is made in step 8, the CPU 38 proceeds to step 10 and performs half cut processing here.

Switching between the full cut and the half cut is performed by changing the amount of electricity supplied to the moving coil device of the head drive mechanism 36.
