Description

Detailed Description of the Invention [Industrial Field of Application] The present invention controls the driving of an image head on a paper placement surface in the X and Y directions of the paper placement surface, and The present invention relates to a method for controlling an automatic drafting machine so as to draw a predetermined diagram.

[Conventional technology]

This type of automatic drafting machine has a paper placement surface, guide rails arranged parallel to each other on both sides of the paper placement surface, and a guide rail that is perpendicular to the guide rail. a movable rail suspended movably; a print head movably attached to the movable rail; a first motor that drives the print head along the movable rail; and a first motor that drives the movable rail along the movable rail. It is composed of a second motor that is driven along a rail, and a controller that controls the motor, and the controller controls the movement of the printing head in a predetermined XY direction on the paper placement surface. A predetermined pattern is automatically drawn on the paper.

[Problem that the invention seeks to solve]

When the drawing work is completed or when the drawing work is interrupted, the moving rail stops on the paper placement surface and maintains its stopped state until the next movement command is given. Therefore, when the paper is to be replaced on the paper placement surface, the moving rail becomes an obstacle, making it difficult to perform the paper replacement operation.

The present invention aims to eliminate the above-mentioned defects.

[Means to solve problems]

In order to achieve the above object, the present invention includes a paper placement surface, a guide rail disposed on the side of the paper placement surface, and a paper placement surface that moves toward the guide rail in a perpendicular relationship to the guide rail. a movable rail 4 movably connected to the movable rail 4; a double line head 6 movably mounted on the movable rail 4; a first motor 16 for driving the print head 6 along the movable rail 4; a second drive for driving the rail 4 along the guide rail;
a motor 18, and a controller 2 that controls the motor.
0, the controller 2
0, program control information for moving the moving rail 4 to a predetermined position away from the paper placement surface in the direction opposite to the printing head mounting side and making it standby, and using the program control information, the moving rail 4 is moved to the predetermined standby position.

[Effect]

Therefore, when plotting is completed or when plotting is interrupted to replace paper, the controller is provided with program control information that allows the controller to move the moving rail to a predetermined position away from the paper placement surface in the opposite direction from the print head installation side and wait. This control information automatically moves the moving rail to the above-mentioned predetermined position.
Wait at that position.

〔Example〕

The structure of the present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

2 is the body of the X-Y automatic drafting machine, and both sides 2a of this
, 2b are provided with guide rails (not shown), to which both ends of the moving rail 4 are slidably attached via an X cursor (not shown). A Y cursor (not shown) is slidably attached to the moving rail 4, and a printing head 6 is fixedly attached to the Y cursor.

A pen support arm 8 is supported on an elevating plate (not shown) of the drawing head 6, and a writing pen 10 is supported on the pen support arm 8.
is supported. The elevating plate of the print head 6 is linked to the output shaft of a solenoid 12 fixed to the substrate of the single print head 6. When the solenoid 12 is energized and its output shaft is driven in one direction, the elevating plate is lowered and the tip of the writing pen 10 touches the paper on the table 14 with a brush determined by the excitation force of the solenoid 12. Contact with pressure.

When the power supply to the solenoid 12 is cut off, its output shaft is driven in the other direction by the return spring, whereby the elevating plate rises to a predetermined position and the tip of the writing pen 10 touches the paper on the table 14. It is configured so that it separates from the When the X motor 16 built into the fuselage 2 is driven by a controller consisting of a microcomputer 20, the Y rail 4 moves along the X rail,
The Y cursor is configured to move along the Y rail 4 when a Y motor 8 built into the body 2 is driven.

The aircraft body 2 has a built-in microcomputer 20,
A keyboard 26 for operating the microcomputer 20 is arranged on a panel of the aircraft body 2. The panel is provided with a remote switch 28 for outputting a drawing start signal and a local switch 30 for moving the Y rail 4 to a predetermined position where it is removed from the paper placement surface. 32 is a host computer connected to the controller 20.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

First, when the microcomputer 20 is powered on, initial settings are performed (steps 1 and 2). The drawing information from the host computer 32 is input to the buffer of the microcomputer 20, and when the level of the mode terminal is in the remote mode (step 6.7),
The above drawing information is supplied to the motor control means of the microcomputer 20. As a result, the motor control means
Outputs forward and reverse drive pulses to drive the motor 16°18.

On the other hand, the pen up/down signal is supplied from the buffer to the solenoid control means of the microcomputer 20, which in turn outputs a signal for energizing or de-energizing the solenoid 12. The above microcomputer 20
The XY motors 16 and 18 and the solenoid 12 are driven by drive control signals from the motor control means and the solenoid control means, and a predetermined drawing is performed on the paper on the paper placement surface of the table 14 (step 10). When one step of drawing is completed, a moving rail removal signal is sent from the host computer 32 to the microcomputer 2 in order to replace the paper.
0, and the buffer shifts to a local mode, that is, a state in which data is received but not outputted (step 3).Meanwhile, a pen-up signal is input to the input terminal of the solenoid control means. As a result, the solenoid control means outputs a pen-up signal (zero current) to the solenoid 12.
The pen support arm 8 of the drawing head 6 rises, and the pen is in the pen-up state. Next, the pulse signal of the unidirectional high-speed pulse oscillation means of the microcomputer 20 is applied to the X and Y motors 1 by the moving rail removal signal of the host computer 32.
6, 18 drivers, X-, Y motor 16
, 18 rotate at high speed in the forward direction, and the moving rail 4 moves at high speed in the +Y coordinate direction in FIG.

The moving rail 4 moves to a predetermined position separated from the paper placement surface on the table 14 in the +Y direction, and the printing head 6 is moved on the moving rail 4 in FIG.

When it moves to the right end, the X and Y motors 16 and 18 stop. The operator replaces the paper on the table 14 while the moving rail 4 is waiting at the set position separated from the paper placement surface. Next, when a remote command signal is input from the host computer 32 (step 6),
The microcomputer 2o drives the X and Y motors 16 and 18 to move the drawing head 6 to the origin position, and then, based on various plotting commands supplied from the host computer 32, the microcomputer 2o drives the X, Y motors 16 and 18. Y
The motors 16, 18 and the solenoid 12 are controlled to draw a predetermined drawing.

Note that even when the 1st drawing operation is interrupted, the moving rail moves to the paper surface release position and the 1st drawing start signal causes the head to
A program is installed in the host computer to move to a position where drawing can be continued.

〔effect〕

As described above, the present invention automatically moves the moving rail to a predetermined paper placement surface release position and waits at that position, so that the work of re-pasting the paper on the paper placement surface can be quickly performed. This has the effect of increasing drawing work efficiency.
