BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing brush used for a plotter for painting ceramics.

[0002]

2. Description of the Related Art Conventionally, a person skilled in the art paints ceramics directly by hand-painting directly on the unglazed or baked ceramics while manually attaching a paint in which a pigment for ceramics is appropriately dissolved with water or oil to a brush.

On the other hand, a plotter for automatically writing characters with a writing brush has already been provided. As shown in FIG. 5, the writing brush accommodates a black ink accommodating body 21 in which felt is impregnated with ink in the brush shaft 1. This black ink collecting body 21 and the tip 3 are connected by a black ink guiding core 22 made of a bundle of fibers.

[0004]

The inventor of the present invention is considering automatically painting ceramics using the plotter, but the ceramics paints are pigment-based and are usually water-soluble. Although it is often used, the paint is likely to settle because it is finely granular, and the above-mentioned conventional plotter writing brush cannot settle the paint because it is settled and clogged. Moreover, it is necessary to change the amount of paint to be attached to the tip of the brush according to the design for painting ceramics, but the amount of paint cannot be adjusted with the above-described brush for a plotter.

Further, when the plotter automatically tries to paint, it is not possible to attach paint to the tip of the brush one by one, so it is premised that the paint is guided from the paint tank to the tip of the brush with a pipe or the like.

The present invention has been made in view of such a situation, and an object thereof is to prevent the settling of the paint and to surely apply the paint to the brush tip when the painting of the ceramics is automatically performed by the plotter. It is an object of the present invention to provide a writing brush for a plotter that can be supplied and can freely adjust the supply amount of paint.

[0007]

In order to achieve the above-mentioned object, the brush for a plotter with a ceramic painting of the present invention has a brush shaft with a brush tip attached to the tip and a paint supply tank provided separately from the brush shaft. Inserted in the brush axis,
It is inserted in the axial direction and the tip is in the axial midway part of the brush tip.

The apparatus is provided with a paint stirring device for stirring and a paint flow rate adjusting valve which is provided in the middle of the paint supply pipe and variably adjusts the flow passage area of the pipe by manual operation.

[0008]

[Function] In the brush for a plotter with a ceramic paint constructed as described above, the paint is directly supplied from the paint tank to the tips through the pipe-shaped supply pipe so that the paint does not settle. Agitated during the flow of the feed line. In addition, the flow rate of the paint supplied to the tip of the brush is adjusted by manually operating the paint flow rate adjusting valve.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments. In the figure, reference numeral 1 is a brush shaft, which is a hollow cylindrical shaft and has a number of fibers aligned at an appropriate length at one end thereof aligned in the axial direction and passed through a tip guide cylinder 2 to form a brush tip 3 Are attached in a connected manner.

A silicone tube 5 constituting a paint supply conduit 4 is axially inserted in the brush shaft 1, and the tube 5 has a tube support whose inner end is provided adjacent to the base of the tip 3. and reach the axially intermediate portion of the brush tip 3 through the plate 6, the outer end is equipped with plotter body a
It is connected to the paint tank not shown and.

In addition, a flexible wire rod 7 is provided at the center of the paint supply pipe line 4 constituted by the silicon tube 5.
Is rotatably held by the center fixing member 8 and is provided in an insertion shape. The inner end of the wire rod 7 reaches the same position as the front end of the paint supply conduit 4 , and the outer end of the wire rod 7 is provided on the plotter body A. It is in contact with a motor (not shown) and is driven by the motor to rotate.

An outer cylinder for forming a valve chamber, in which a sliding inner cylinder 9 having a bottomed cylindrical shape is rotatably and slidably fitted and housed in a middle portion of the paint supply conduit 4 in the brush shaft 1. A knob 11 provided on the side peripheral surface of the sliding inner cylinder 9 has a slot 12 extending in the circumferential direction formed on the side peripheral surface of the valve chamber forming outer cylinder 10 and the brush shaft 1, It penetrates 13 and projects outside the brush shaft 1.

The outer cylinder 10 for forming the valve chamber is formed to have substantially the same diameter as the inner diameter of the brush shaft 1, and the inner sleeve 9 for sliding is formed to have the same diameter as the inner diameter of the outer cylinder 10 for forming the valve chamber. And a bottom part of the sliding inner cylinder 9 and a valve chamber forming outer cylinder for supporting the sliding inner cylinder 9.
Flow control cut holes 15, 16 in the partition-shaped support plate 14 provided in 10.
Have been pierced respectively. Flow rate control notch holes on both cylinders
15, 16 are formed in an arc shape along the circumference of a circle drawn with the same diameter with the center of each cylinder 9, 10 as the center, and by the rotation of the sliding inner cylinder 9, The mutual matching area is variable.

On the other hand, the wire 7 is an outer cylinder 10 for forming a valve chamber.
The wing pieces 17 and 18 are attached and fixed respectively above and below the partition-shaped support plate 14. A sealing rubber ring 20 fixed by a vertical movement prevention ring 19 is attached to the penetrating portion of the partition rod-shaped support plate 14 of the wire 7 to seal the penetrating portion.

Thus, in the brush for a ceramic painter plotter of the present invention constructed as described above, the paint is directly guided and supplied from the paint tank of the plotter body A to the brush tip 3 through the paint supply pipe 4. However, at that time, the wire rod 7 is rotationally driven by the motor of the plotter body A in the paint supply pipe line 4.
Accordingly, the winglets 17 and 18 are rotated accordingly, so that the paint is agitated to prevent the precipitation of the pigment and is reliably supplied to the brush tip 3.

Further, if the knob 11 is operated to move left and right as necessary, the matching area of the flow rate adjusting cut holes 15 and 16 is changed. Therefore, the paint supplied to the tip 3 through the cut holes 15 and 16 is supplied. The flow rate of changes.

[0017]

[Effect] Since the present invention is configured as described above, the following effects can be obtained. (1). From the paint tank provided separately from the brush axis,
Through the paint supply line for inserting axially the paint on the brush tip
So as to directly induce, moreover, is provided with the paint stirrer for mechanically stirring paint in the paint supply line can be induced to reliably brush tip to prevent precipitation of the paint pigment. (2). Moreover, the paint stirring device is a flexible line.
Insert the material into the paint supply line and the tip of the line is the end of the line.
The pipe in the axial direction until it reaches
The paint in the paint supply pipe is agitated by rotating the paint
Since it was done, everything along the entire length of the paint supply pipeline
It is possible to stir the paint on the
It can be continuously agitated continuously by the motor drive.
Therefore, even if you stop stirring for a while, a face that will settle
Reliable and continuous even with paints that do not get clogged
Then it can be supplied to the tip of the brush. (3). At the tip of the brush, a paint supply tank provided separately from the brush axis
Since the paint is supplied from the paint via the paint supply pipe,
A large amount of painting can be performed continuously. (4). Since a flow rate adjustment valve that changes the flow passage area of the pipeline by manual operation was installed in the middle of the paint supply pipeline, operate this according to the pattern to freely adjust the amount of paint supplied to the brush tip. You can
