Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] 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, the present invention relates to a plotter capable of drawing with a pencil lead using a pencil pen.

[Conventional technology]

Plotters are often used by being connected to an external control device, such as a CAD device, and are widely used because they enable precise plotting.

Conventionally, this type of plotter generally uses an ink pen for drafting. However, since this ink pen cannot be erased and corrections are difficult, there is a strong desire for a pen that uses an erasable pen. For this reason,
Recently, an increasing number of plotters of this type are equipped with erasable pencil pens.

By the way, as such a pencil pen, there is a conventional type of cloth type. That is, it had a chuck mechanism for gripping and releasing the pencil lead, similar to a pencil pen as a writing instrument, and a knock mechanism for opening the chuck portion of this chuck mechanism.

[Problem that the invention seeks to solve]

However, such pencil pens had the following drawbacks. First, in this pencil pen, it is impossible to use the pencil lead until its end due to its structure, so when the pencil lead wears out, it has to be removed.

Furthermore, in such pencil pens, those equipped with a single pencil lead have the disadvantage that when the pencil lead is used up, a new one must be replenished.

For this reason, the conventional plotter using a pencil pen has the disadvantage that automatic plotting cannot be performed when plotting requires a long overall writing distance.

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

[Means for solving problems]

Therefore, in the present invention, the plotter is provided with a lead supply/discharge holder for supplying/discharging pencil leads.

[Effect]

A special holder is provided for supplying and discharging pencil lead to and from the pencil pen, so when the pencil lead of the pencil pen wears out,
A pencil pen is held in this dedicated holder, the worn out pencil lead is removed, and a new pencil lead is supplied.

In this case, the plotter is equipped with another pencil pen, and when one pencil pen becomes unable to write due to consumption of its lead, the other pencil pen is used to write, and the previous pencil pen is used to write. During this time, the used pencil lead is removed by the lead supply/discharge holder and a new pencil lead is supplied. With this configuration, the interruption time for drawing can be minimized. In addition, by using a plurality of pencil pens in this way, the rotation of the use of the non-writable pencil pen and the writable pencil pen is stored in advance in the form of a program in the controller built into the plotter. In some cases, automatic drawing can be performed.

〔Example〕

1 to 4 are configuration explanatory diagrams showing one embodiment of the present invention, respectively. FIG. 1 is a front view showing an example of the overall structure of the device of the present invention, and FIGS. A first embodiment diagram showing a core discharging holder, and FIG. 4 are diagrams showing a second embodiment of this core supply/discharge holder.

In the figure, 1 is an XY plotter, 2 is a recording surface, and 3 is an XY plotter.
A moving mechanism, 4 a carriage, 5 a moving part pen holder, 6
is a storage pen holder, °7 is a wandering lead holder, and 8 is a pencil pen.

First, an overview of the present invention will be explained with reference to FIG.

This XY Bronta l is a so-called flatbed type plotter, but a recording pen such as a pencil pen 8 is held in a movable pen holder 5 attached to a carriage 4.
A figure is created on a recording medium (not shown) that is freely moved by the XY moving mechanism 3 and placed on the recording surface 2. The recording pen held in the movable pen holder 5 is stored in a plurality of pen holders 61, 62, . . . provided in the storage pen holder 6.
, 69 are automatically exchanged, making it possible to record with a large number of recording pens.

Now, for example, assume that the recording pen 8 is held in the ninth pen holder 69 of the storage pen holder 6.

The pencil pen 8 is taken into the movable pen holder 5 and recording is performed using the pencil pen 8. When this pencil pen 8 becomes unable to write due to consumption of its pencil lead, drawing is temporarily interrupted and this pencil pen 8 is transferred to the lead supply/discharge holder 7. The lead supply/discharge holder 7 removes the worn out pencil lead of the pencil pen 8.
Replenish new pencil lead. In this way, the pencil pen 8 which has become capable of writing is taken into the movable pen holder 5 again, and the pencil recording is continued.

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

The pencil pen 8 is supplied to and discharged from the lead holder 7 by the movable pen holder 5.
is maintained. The core supply/discharge holder 7 includes a pen holding member 71,
It has a solenoid 72, a knock pushing member 73, a sensor support member 74, and a core receiver 75.

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

Now, in the state shown in FIG. 2, the solenoid 72 is energized multiple times by commands from an internal electric circuit (not shown). As a result, the knock pushing member 73 moves the knocking mechanism of the pencil pen 8 up and down multiple times. As a result, a new built-in pencil lead 82 is fed out.

Therefore, the worn out pencil lead 82 is pushed out by a new pencil lead 82 and falls into the lead receptacle 75.

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

In place of the optical sensor 741, the lead supply/discharge holder 7 in FIG. In addition to providing an electrode 762, the distal tip 84 of the pencil pen 8 is formed of a conductive material, and the removal of the lead is confirmed by conducting and discharging the current.

Note that the core receptacle 75 in the devices shown in FIGS. 2 and 3 is configured to be able to be pulled out of the device.

FIG. 4 shows a lead supply/discharge holder for a pencil pen 8 having only one pencil lead 82, instead of using the pencil pen 8 that incorporates a plurality of pencil leads 82 as shown in FIGS. 2 and 3. 7 and shows its main parts.

When the pencil pen 8 whose pencil lead 82 has worn out and is no longer able to write is held in the pen holding member 71 of the lead supply/discharge holder 7, the pencil lead holder 78 positioned at the top of the pencil pen 1 is moved at a predetermined angle by the pulse motor 77. Rotate. Then, the pencil lead holding part 781 of the pencil lead holder 78 matches the pencil lead drop hole 121 provided in the device housing 12 that holds the pencil lead holder 78 and the pulse motor 77, and the pencil lead 82 is inserted into the pencil pen 8. will be replenished. The solenoid 72 is energized a predetermined number of times, the knock mechanism 83 of the pencil pen 8 moves up and down a predetermined number of times, and the worn-out pencil lead 82 is removed by this new pencil lead 82.

By the way, when the pencil pen 8 is made to be unable to write due to the consumed pencil lead 82, the compensating operation is performed each time in the lead supply/discharge holder 7, during which the recording operation is interrupted. As a result, the overall recording time increases. In this case, by preparing a plurality of pencil pens 8, for example two, and using another pencil pen 8 when one pencil pen cannot write, it is possible to minimize the recording interruption time. can.

〔Effect of the invention〕

As described above, according to the present invention, since the pencil lead supply/discharge holder is provided in the profiler, the pencil lead can be replaced automatically, and thus automatic drawing can be performed for a long time.
