Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to automatic fixing (6).

[Technical background of the invention and its problems] It was impossible to produce uj++ beyond the conventional automatic drawing machine TI'iAO because of the low precision of winding and the inability to detect positional deviations in the X and Y directions. For this reason, I had no choice but to use a cylindrical drafting machine with free longitudinal direction (Y direction) for automatic drafting.

Since the circular shape can extend up to several tens of meters in the Y direction, it is ideal for drawing long drawings in the Y direction.However, the guide on which the drawing head is placed is placed at a fixed position, and direction)
In order to draw freely, it is important to not move the paper in the Y direction, that is, to draw freely. Therefore, the circle f
The drawback of j rooster 1 shi is that you cannot be sure of the pattern until the -ga:ki is completed.

Drawing paper is used in roll form and is placed in advance on the drawer roll 1 before drawing. A drawing paper 2 is pulled out from a drawer roll 1, pasted on a table 3, and the tip of the pulled out part is fixed to a winding roll 4 using adhesive tape or the like.

After fixing, the drawer roll 1 is fixed, and the winding roll 4 is rotated to take up the slack in the drawing paper. Thereafter, the drawing paper 2 is fixed to the table 3 using a suction mechanism such as a vacuum, and air or the like is removed from between the table 3 and the drawing paper 2 to prevent the drawing paper 2 from being torn by the drawing pen.

After completing the above drawing, drawing data is input to the automatic production section; controller 5. This drawing data contains the winding amount in advance.

Before starting drawing, the drawer roll l can be unlocked and removed freely.

After that, drawing starts, and at the end of one drawing, the suction 777 mechanism is stopped, and the winding roll ljA of 1jlr constant is transferred from the automatic drawing 4 controller 5 to the servo system.
A drive command is issued to the driving motor 6. The winding roll drive motor 6 is equipped with a detector 7 for detecting the amount of weeding, and a signal from the detector 7 drives the winding roll driving motor 6 until a predetermined winding thickness is reached.

As described above, although the conventional system performs control regarding winding and 9i, it does not control the deviation in the XY directions. For this reason, even though it was possible to draw a plurality of drawings with the maximum AO, it was impossible to draw one large-sized picture because the positions of the front and back lines would be shifted.

For this reason, some people are disappointed when they wish to create large-scale drawings on a flatbed type where the progress of drawing can be seen. We decided to reverse the misalignment loss in the XY direction, but
If +ifi correction is performed in the direction, the mechanism becomes +jJ-M+, so the deviation in the X direction is corrected by only the 1- deviation in the Y direction by keeping the drawing paper tension constant.

[Summary of the Invention] The present invention comprises drawing paper stacked in a roll, a drawer for pulling out the drawing paper by dividing it into a winding horn, and a flat plate for drawing out the drawing paper after being rewound from the drawer. , a winding machine that stretches and winds up the drawing paper on this flat board, a drive machine that drives this winding machine, a winding leaf detector that detects the winding amount of the drawing paper, and a predetermined In an automatic drawing device comprising a stop function that stops the driving mode when a set winding amount is reached, a position adjustment device that adjusts the crystalline position of the drawing paper;
In conjunction with this position adjustment device, the height of the drawing paper can be adjusted by adjusting the height of the drawing paper.
A drive machine control function that controls the drive machine (according to the signal from the winder and the winder) and the position signal and the sardine angle.

Automatic fixing equipment equipped with motive 1lIij control device
It is 7. That is, the present invention provides a flatbed type automatic drafting machine that includes a winding mechanism, a winding servo motor, a guide rail between the table and the width roll, an fM detector located on the guide rail, and a torque motor for the drawer roll t (11). This is an automatic drawing device that can keep the tension of the drawing paper constant and wind it up while detecting the winding (i:).

[Embodiments of the Invention] Next, an embodiment of the present invention will be described. Fig. 2 shows a drawer roll 1 for rewinding and pulling out drawing papers 2 and 1 drawing paper a stacked in a roll, and Return and pull out 1st
A table 3 on which the drawn drawing paper 2 is placed, a winding roll 4 that stretches and winds up the drawn drawing paper 2 on the table 3, and a percentage removal roll 4.
A drive motor 6 for driving the 1h drive motor 6, a 1st cut amount detector 7 for detecting the width 1 of the 1st generation 2, and the drive motor In an automatic drawing device consisting of a stop () function that stops the drawing paper 2, a side roll A that makes the height position of the drawing 1 (L, 2 61), and a side roll A that moves the drawing paper 2 in conjunction with the side roll 11.
The motor 6 for the pivot Wdt is activated by the 4-way output device 12 which detects the height position j+''(, and the position 1/( from the detector 12, the signal 12a and the quantity number 7a from the winding M detector 7). Automatic drafting 4t2 controller for sterilization 1 and position signal 12
This figure shows an automatic drafting device equipped with a torque motor 1b system (iIII device) which drives a torque motor 1a for driving a drawer by means of a and quantity number 7a.

The pull-out roll 1 is equipped with a torque motor 1a and a torque motor control device 1b in order to maintain constant tension with respect to the take-up roll 4.

The drawing paper 2 with a pull-out roll 1 is passed over a guide rail 11 and the leading end 1 of the drawing paper 2 is fixed to a winding roll 4. Torque motor jl of drawer roll 1 at the end of fixing
When the i control device filb is turned on, a constant current is applied to the torque motor 1a, and the drawer roll 1 is fried.

At this time, the drawing paper 2 is adjusted in height between the guide roll 11 and the drawer roll 1 to such an extent that the suction device Y+l is not required on the table 3. Thereafter, drawing data is input to the automatic drawing controller 5 to perform drawings 1...1. At the end of the drawing, the automatic drafting machine controller 5 issues a drive command to the torque motor 9j1'' 1b and the motor 6 for driving the winding roll 1 attached to the winding roll 4. In the torque motor control device fkt, 1b, the current value is changed according to No. 46 so that the winding roll driving motor 6 can take up the winding roll and maintain a tension that does not cause the roll to slip in the X direction. Therefore, the winding roll drive motor 6 is driven without being overloaded, and based on the signal from the detector 7 attached to the drive motor 6, the automatic drafting machine controller 5 drives the winding roll until a predetermined winding amount is reached. drive the motor 6.

Upon completion of the predetermined winding l;, the automatic drafting machine controller 5 applies fJJ4 to the guide roll A and the guide roll A.
A comparison is made with the signal from detector B.

If there is one light, the % error chi is corrected for the drawing data in the Y direction of the next drawing/direction, and drawing continues.

[Effects of the Invention] According to the present invention, the Y direction is always corrected, and it becomes possible to draw images of A, O size or larger on a flatbed type drawing machine.
