Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a plotter for tape materials,
In particular, the present invention relates to a tape material plotter (hereinafter referred to as a plotter) for writing or engraving characters, symbols or diagrams on the surface of the tape material.

[0002]

2. Description of the Related Art As the plotter, a metal tape material called Sinai material used for processing steel structures such as bridges, steel frames, and towers is dimensioned, and characters, symbols or diagrams for work procedures are written or stamped. There is a plotter to do.

In this plotter, a long tape material is wound on a reel in a roll shape, the tape material wound on the reel is fed out on a recording surface by a predetermined length, and the tape is fed onto the recording surface. Characters, symbols or diagrams are entered or engraved on the surface of the material. More specifically, a carriage holding a pen or a cutter is moved in the XY directions by computer control on the surface of the tape material that is fed onto the recording surface. Characters, symbols or diagrams are written or marked on the surface of the tape material with a pen or a cutter held by the carriage. The tape material on which characters, symbols or diagrams are written or engraved is wound from the recording surface to a reel outside the recording surface.
Hereinafter, the above operation is sequentially repeated to write or engrave characters, symbols, or diagrams on the surface of the long tape material at predetermined lengths. Then, by forming or engraving letters, symbols, or diagrams over the entire length of the surface of the long tape material, called a Sinai ruler, to form an original size ruler for steel material such as steel frame dimensioning, drilling, welding work, etc. There is.

While some tape materials for forming the Sinai ruler have a total length of several tens of meters, letters on the surface of the tape material called Sinai ruler used for dimensioning, drilling, welding, etc. of steel materials such as steel frames, The accuracy of the entry or marking position of the symbol or diagram is required. For example, the dimensional accuracy of a Sinai ruler used for steel frame dimensioning is 12
High precision of ± 1 mm or less per m is required.

[0005]

However, in the above-mentioned conventional plotter, when the tape material wound on the reel is fed by the feeding means to the recording surface by a predetermined length, the feeding length accuracy is poor, and it is difficult to put the tape material on the recording surface. Even if characters, symbols, or diagrams were accurately written or marked on the surface of the fed tape material, the positions of the characters, symbols, or diagrams plotted or marked with respect to the entire length of the tape material were incorrect.

The present invention has been made in view of the above problems, and it is possible to accurately and accurately feed a tape material wound in a roll on a reel or the like onto a recording surface by a predetermined length using a feeding means. The purpose is to provide a plotter that can.

[0007]

In order to achieve the above object, the plotter of the present invention has a tape material wound in a roll shape, which is fed to a recording surface by a predetermined length by using a feeding means, and the recording surface In a tape material plotter for writing or marking characters, symbols or diagrams on the surface of the tape material that has been fed out, a marking means for writing or marking a positioning mark on the lower surface of the tape material fed onto the recording surface, and the marking means. A sensor for detecting a positioning mark on the lower surface of the tape material, which is filled in or engraved with, and which is provided by being separated from the marking means in the feeding direction of the tape material by the unrolling length of the tape material which is unrolled on the recording surface by the predetermined length. And a stop means for stopping the feeding means when the sensor detects the positioning mark. There.

In the plotter of the present invention, the stop means detects the ambient temperature of the tape material, and based on the detected temperature, from the moment the sensor detects the positioning mark until the feeding means is stopped. It is preferable to provide a temperature correction mechanism that adjusts the time length.

[0009]

In the plotter having the above construction, when the tape material wound in a roll shape is fed onto the recording surface by using the feeding means, the marking means writes or marks a positioning mark on the lower surface of the tape material fed onto the recording surface.

Next, the tape material wound in a roll shape is continuously fed onto the recording surface by using the feeding means, and the tape material is fed onto the recording surface by a predetermined length and is fed onto the recording surface. Then, when the positioning mark written or engraved on the lower surface of the tape material reaches the upper side of the sensor which is separated from the marking means by the feeding length of the tape material in the feeding direction of the tape material, the positioning mark written on the lower surface of the tape material or A sensor detects the engraved positioning mark. Then, when the sensor detects the positioning mark on the lower surface of the tape material, the stopping means is used to stop the feeding means,
The feeding of the tape material wound into a roll onto the recording surface by the feeding means is stopped.

Hereinafter, the above operation is repeated in sequence.

Then, the tape material wound in a roll shape is recorded by the feeding means by the length of separation between the portion having the marking means and the portion having the sensor, which corresponds to the feeding length of the tape material. It is possible to pay out precisely on the surface.

Further, the stop means detects the ambient temperature of the tape material, and the time from the moment when the sensor detects the positioning mark to the time when the stop means stops the feeding means based on the detected temperature. With a plotter equipped with a temperature correction mechanism that adjusts lengthwise, even if the tape material expands or contracts due to the ambient temperature where the tape material is placed, the expansion and contraction amount is detected by the temperature correction mechanism and Adjust the length of time from the moment when the written or engraved positioning mark is detected by the sensor until the feeding means is stopped by the stopping means, and the feeding length that the tape material wound in a roll is fed onto the recording surface using the feeding means. You can fine-tune the height. Then, even if the tape material expands and contracts due to the ambient temperature in which the tape material is placed, the tape material is accurately and sequentially delivered onto the recording surface by the same delivery length as the delivery length of the tape material at a steady temperature, for example, 20 ° C. It is possible to continue.

When the feeding length of the tape material fed onto the recording surface is adjusted by using the temperature correction mechanism, characters, symbols, or characters to be written or marked on the surface of the tape material with a pen or a cutter held by the carriage are used. Also in the line drawing, if the vertical and horizontal lengths, entry or engraving position, etc. are not finely adjusted according to the ambient temperature where the tape material is placed, write the letters, symbols or line drawings on the tape material surface with high accuracy or Needless to say, it cannot be engraved.
