Description

The present invention relates to a plotter that uses a pen to create a predetermined drawing based on a drawing signal from an external control device. More specifically, it relates to a plotter capable of drawing with a pencil lead by using a pencil pen.

[Conventional technology]

The plotter is often used by being connected to an external control device, for example, a CAD device, and is widely adopted because it enables precise drawing.

Conventionally, in this type of plotter, one using a drawing ink pen has been generally used. However, since this ink pen cannot be erased and correction is difficult, it is strongly desired to use an erasable pen. For that reason,
In recent plotters of this type, an increasing number of devices are equipped with erasable pencil pens.

By the way, as such a pencil pen, there has been a conventional one as follows. That is, it has a chuck mechanism for gripping and releasing the pencil lead, and a knock mechanism for releasing the chuck portion of the chuck mechanism, similar to a pencil pen as a writing tool.

[Problems to be solved by the invention]

However, such a pencil pen has the following drawbacks. First, in this pencil pen, it is impossible to use the pencil lead to the end because of its structure, and therefore, there is a drawback that it has to be removed when the pencil lead is consumed.

Further, in such a pencil pen having one pencil lead, there is a drawback that the pencil lead must be newly replenished when it is consumed.

Therefore, in the conventional plotter using the pencil pen, there is a drawback in that the automatic drawing cannot be performed when the drawing with a long writing distance is performed comprehensively.

The present invention has been made with the object of eliminating this drawback.

[Means for solving problems]

Therefore, in the present invention, a dedicated supply / discharge core holder for supplying / discharging the pencil lead to / from the plotter,
Knocking means for operating the knocking mechanism of the unrecordable pencil pen held by the supply / discharge core holder is provided.

Further, a core lead receiver for holding a pencil lead to be removed from a non-recordable pencil pen is provided below the supply / discharge lead holder.

In addition, a discharge lead confirmation sensor for confirming that the pencil lead has been removed from the unrecordable pencil pen is provided below the supply / discharge lead holder.

[Action]

Since a dedicated holder for supplying and discharging the pencil lead to the pencil pen is provided, if the pencil lead of the pencil pen is exhausted,
A pencil pen is held in this dedicated holder, the consumed pencil lead is removed, and a new pencil lead is supplied.

In this case, another pencil pen is provided on the plotter, and when one pencil pen becomes unable to write due to the consumption of its pencil lead, write with the other pencil pen. In the meantime, the supply and discharge core holder removes the consumed pencil lead and supplies a new pencil lead.
In such a case, the interruption time of drawing can be minimized. In addition, using multiple pencil pens in this way, the rotation of the use of the unreadable and unwritable pencil pens is stored in advance in the controller built into the plotter in the form of a program. When configured, it is possible to perform an automatic diagram.

In addition, the pencil lead removed from the pencil pen that cannot be written is held in the lead-out receptacle, and the lead-out confirmation sensor provided in the lower part of the feed / feed core holder is an unnecessary pencil that is removed from the pencil pen. Detect the core.

This XY plotter 1 is a flatbed type plotter, but a recording pen such as a pencil pen 8 is a carriage 4.
A rectangular shape is created on a recording medium (not shown) held on a moving portion pen holder 5 attached to the recording medium and freely moved by an XY moving mechanism 3 and placed on the recording surface 2. The recording pens held by the moving portion pen holder 5 are automatically exchanged with the recording pens held by a plurality of pen holding portions 61, 62, ... Is possible.

Now, for example, it is assumed that the recording pen 8 is held by the ninth pen holding portion 69 of the storage pen holder 6. The pencil pen 8 is taken into the moving portion pen holder 5 and recording is performed by the pencil pen 8. When the pencil pen 8 cannot be written due to the consumption of the pencil lead, the drawing is temporarily stopped and the pencil pen 8 is moved to the supply / discharge core holder 7. The supply / discharge core holder 7 removes the worn pencil lead of the pencil pen 8 and supplies a new pencil lead. In this way, the pencil pen 8 is ready for writing.
Is again taken into the moving unit pen holder 5, and pencil recording is continued.

FIG. 2 shows an example of the supply / discharge core holder 7.

The pencil pen 8 is fed by the moving part pen holder 5
Held in. The supply / discharge core holder 7 includes a pen holding member 71, a solenoid 72, a knock pushing member 73, and a sensor support member 74.
And, it has an exhaust core receiver 75.

The apparatus shown in FIG. 2 has a plurality of pencil leads built in the pencil pen 8 itself.

Now, in the state of FIG. 2, the solenoid 72 is excited a plurality of times by the command of the internal electric circuit (not shown). As a result, the knock pushing member 73 moves the knock mechanism of the pencil pen 8 up and down a plurality of times. This enables a new built-in pencil lead
82 is rolled out. For this reason, the consumed pencil lead 82 is pushed out by the new pencil lead 82, and falls onto the core discharge receiver 75.

At this time, in order to detect whether or not the consumed pencil lead 82 is completely removed, the supply / discharge core holder 7 is provided with an optical sensor 741 held by the sensor support member 74.

In order to confirm the removal of the pencil lead 82, the supply / discharge core holder 7 of FIG. 3 is provided with a first electrode 761 and a second electrode 761 each having a carbon brush or a carbon fiber 763 attached to the tip thereof instead of the optical sensor 741.
