Abstract

PROBLEM TO BE SOLVED: To prevent sagging from being generated on the drawing part of flexible material. SOLUTION: A flexible batten is produced by feeding flexible material which is drawn by a drawn line head along a drawing part 104 by a prescribed amount. Pinch roller mechanisms 76, 52 which pinch the flexible material with its upper part roller and its lower part roller are formed at the drawing part 104, a main motor 102 is jointed to the roller of one pinch roller mechanism 76, and a DC motor 75 is jointed to the roller of the other pinch roller mechanism 52. When drawing is conducted against the flexible material on the drawing part 104, the excitation of the DC motor 75 is cut of, and a controller feeds the flexible material at a high speed to a position a few centimeter to this side of a targeted value by driving the main motor 102 at a high speed. After that, the flexible material is fed by the targeted value +α by the low-speed driving of the main motor 102. In order to eliminate sagging 126 of the flexible material, the rotation of the main motor 102 is reversed at a low speed to return the flexible material by -Α. When the flexible material is returned by -α, excitation is applied to the DC motor 75 in a flexible material feeding direction.

8) is a drawing area (1) provided on the substrate (2).
It is configured so that the pen can be exchanged with the pen line (114) provided on the side of 12). The board (2) is provided with a keyboard (116) with a display (117). next,
An operation of setting the sini material (8) wound on the supply reel (10) in the sini material transport path on the substrate (2) will be described. When setting the Sinai material (8), the handle (9) of the Sinai material drive (76) is used.
2) Loosen in advance and raise the holder plate (96). In this state, the Shinai material (8) drawn from the supply reel (10) is transferred to the Shinai material regulation guide (3).
6) Between the rollers of (46), the Sinai material drive section (76)
Press roller (80) (82) and drive roller (78)
And between the upper and lower rollers of the guide for regulating shinai material (48), and bring it to the supporting surface of the shinai material of the drawing unit (104).

Further, the Sinai material (8) is pulled out, and the Sinai material regulation guides (50) (52) (54) (38)
And between the upper and lower rollers of the take-up reel (12). next,
The handle (92) is rotated by hand, and the holder plate (9) is rotated.
6) is lowered, and the surfaces of the pressing rollers (80) and (82) are placed on the front and rear positions separated by a predetermined distance from the top (C) of the surface of the driving roller (78). Crimp. The sini material (8) on the drive roller (78) bends in a wave shape by the pressure of the front and rear pressing rollers (82) and (80), and the sini material (8) is driven by the driving roller (78) and the pressing roller (80). ) (82) is brought into surface contact with high frictional force.

In the above configuration, the drawing section (104)
In the Shinai material (8) on the Shinai material supporting surface of (1), marks such as characters, graphics, and symbols are drawn by the image head (108) based on the drawing information of the computer over a predetermined range. When the plotting of the predetermined range is performed,
A predetermined amount of the shinai material (8) is fed in the unwinding direction. When feeding the raw material, take-up motor (34)
And the main motor (102) are simultaneously rotated at high speed. At this time, the DC motor (75) is de-energized and rotates freely. The main motor (102) controls the speed and acceleration, while the take-up motor (34) controls the take-up reel (1).
Since the diameter of the Sinai material in 2) changes and speed control is difficult, a constant voltage is supplied to this. The controller stops the main motor (102) once 5 cm before the target movement amount of the Sinai material (8). Next, the take-up motor (3) is driven at a low speed to remove the slack (126) of the sini material (8) on the drawing section (104) of the substrate (2).
4) Rotate in the winding direction. When the tension of the shinai material (8) increases and the upper roller (40) of the shinai material regulating guide (38) moves against the tensile force of the spring (122), the sensor (124) is turned on and the winding is performed. The take-off motor (34) stops.

Next, the controller controls the Sinai material (8)
The main motor (102) is rotated in the forward direction at a low speed in order to increase the feed accuracy of the main motor (102), and when the Sinai material (8) has been fed by 5 cm + α, the driving of the main motor (102) is stopped. Next, in order to remove the slack of the Sinai material (8), the main motor (102) is driven in the reverse direction to return the Sinai material (8) by α. When tension is applied to the Sinai material (8), the upper roller (40) moves against the force of the spring (122), the sensor (124) is turned on, and the winding motor (34) is stopped. Is to prevent the take-up motor (34) from pulling too much on the shiny material (8), thereby allowing the main motor (10)
2) can be reduced. Sinai material (8)
As shown by the dotted line in FIG. 1, when the paper is fed straight without being attached to the take-up reel (12), the signal of the sensor (41) for detecting the slack of the material (8) of the take-up reel (12) is ignored. I do.

Further, the excitation of the DC motor (75) is turned off, and the controller drives the main motor (102) at a high speed until the Sinai material (8) is 5 cm before the target value of the forward feed amount. . Thereafter, the Sinai material (8) is fed by 5 cm + α with the low speed drive of the main motor (102). Next, to remove the slack (126) of the Sinai material (8), the main motor (102) is reversely rotated at a low speed, and the Sinai material (8) is returned by -α. However, when the Sinai material (8) is fed for several meters and the steel strip (8) is attached to the ground or an external force is applied, the drawing unit (104)
A large slack appears on the upper Sinai material (8). Therefore, when returning the Sinai material (8) by -α, the DC motor (75) is excited in the Sinai material feed direction. When the main motor (102) is stopped, the DC motor (102) is excited to apply a force that does not pull the Sinai material (8). Further, at the time of drawing by the drawing head (108), the DC motor (102) is energized in the position control or the Sinai material feeding direction.

In the case where a shiny material such as a film is used instead of the steel strip, when the shinai material is fed, when the winding portion is stopped, that is, in the above description of the operation, 5 cm is used. Meter + α slowly send-
When returning by α, the DC motor (75) is excited in the feed direction so that the slack of the Sinai material (8) can be removed. Also, the DC motor (7
By applying the excitation in 5), it is possible to prevent the slack of the Sinai material. The feed amount of the Sinai material (8) in the X-axis direction is determined by an encoder (74) provided on a lower guide roller of the Sinai material regulating guide (52).
The signal is converted into a pulse signal and fed back to the controller. The controller recognizes the feed amount of the Sinai material (8) based on the feedback signal. In this way, marks are sequentially drawn on the shinai material (8), and a shinai ruler having a desired length can be created.

[0018]

Since the present invention is constructed as described above, there is an effect that the slack of the Sinai material on the drawing portion can be prevented.
