Description

[Detailed Description of the Invention] <Industrial Technical Field> The present invention relates to a cleaning machine for cleaning screen plates used for printing, etc., and the present invention relates to a cleaning machine that cleans screen plates used for printing, etc., and is capable of reliably discharging residues deposited on the bottom of the cleaning tank from the tank. It is related to washing machines.

<Prior Art> Conventionally, a washing machine used for washing a screen plate was equipped with a drainage mechanism as shown in FIG.

In the figure, reference numeral 14 denotes a cleaning tank for cleaning the screen plate, and a drain valve 15 is provided at the bottom of the cleaning tank 14.

And 16a and 16b are vibrators,
The vibrators 16a and 16b are connected to the cleaning tank 14.
Apply mechanical vibration to the bottom plate of the

As shown in the figure, the bottom surface of the cleaning tank 14 is formed in an inclined shape, and the drain valve 15 is provided at the lowest point of the slope. The precipitated ink (residue) (not shown) then slides down to the lower part of the bottom plate.

As a result, when the drain valve 15 is opened, the ink is discharged to the outside of the cleaning tank 14 together with the cleaning liquid.

<Problems to be Solved by the Invention> In the conventional method, even if the ink is drained while applying mechanical vibration, most of the ink does not fall toward the drain valve 15, and the ink does not fall into the cleaning tank. It will remain within 14.

Moreover, since the ink is in the form of sludge, it is difficult to pass through the pipe, and it may become clogged midway through, preventing it from flowing out from the drain valve 15.

<Means for Solving the Problems> The present invention provides a cleaning machine having a cleaning tank for cleaning screen plates, which includes a drive motor at the top of the first side surface inside the cleaning tank and one roller at the bottom. , two rollers are provided above and below a second side surface parallel to the first side surface,
a wire cross-linking device in which the drive motor and three rollers are cross-linked with a wire in parallel to a third side surface perpendicular to the first and second side surfaces; A residue accumulation member includes a spatula and an urging member that presses the spatula against the bottom surface of the cleaning tank with a constant force, a wire fixing member that connects the residue accumulation member to the wire, and a wire fixing member that connects the residue accumulation member to the wire; The third guide rail for regulating the movement of the wire fixing member
a residue accumulation member provided on a side surface of the cleaning tank and a guide support portion into which the guide rail is to be inserted; A discharge device is provided, which includes a discharge port for discharging the residue collected as the tools move, and a pump for discharging the residue from the discharge port to the outside of the cleaning tank.

<Function> With such a configuration, the cleaning machine according to the present invention can easily accumulate the residue precipitated on the bottom of the cleaning tank, and by exerting a discharge action on the accumulated residue, Residues can be reliably removed to the outside of the cleaning tank without clogging the pipes.

<Example> Hereinafter, the configuration of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of a cleaning mechanism according to an embodiment of the present invention.

In the figure, 1 is a cleaning tank, and the cleaning tank 1 is used to clean a screen plate (not shown).
The screen plate is used when printing characters, etc.
Ink is applied.

When the screen plate is cleaned, ink (residue) accumulates on the bottom surface (bottom plate) 1a of the cleaning tank 1, so in this embodiment, a residue accumulation member (schema) 2 is provided to accumulate the accumulated ink.

The accumulation member 2 is located on the bottom surface 1a of the cleaning tank 1.
By moving the spatula 3, ink (not shown) is scraped into the drain port 4, and the collected ink is drained into the drain port 4 by the action of the drain pump 5. is forcibly discharged to the outside of the cleaning tank 1.

The spatula 3 is moved by motor drive. That is, the spatula 3 is attached to the wire fixture 7 by a spatula attachment fitting 6. The wire fixture 7 is connected to and deviates from the drive wire 8,
Furthermore, the structure is such that the rotational force of the drive motor 9 is transmitted to the drive wire 8.

As shown in the figure, the drive wire 8, together with the drive motor 9, connects three rollers 10a and 10.
b, 10c, the drive wire 8 is operated by the rotation of the drive motor 9, and the wire fixture 7 is moved accordingly.

The spatula 3 is applied to the bottom surface 1 of the cleaning tank 1 under a constant load by a tension spring (biasing member) 11.
It is pressed against a.

Further, a portion 12 of the stacking member 2 is fitted into a guide portion (guide rail) 13, and movement of the wire fixture 7 is regulated by the guide portion 13.

With the above-described structure, when the drive motor 9 operates, the accumulating member 2 moves along the guide portion 13 at the bottom of the cleaning tank 1. Along with this, the spatula 3 of the accumulating member 2 moves while being in contact with the bottom surface 1a of the cleaning tank 1 under a constant load, and removes the ink (not shown) precipitated on the bottom surface 1a of the cleaning tank 1. Collect the liquid near the drain port 4.

As described above, the ink collected near the drain port 4 is discharged from the drain port 4 to the outside of the cleaning tank 1 by the draining action of the drain pump 5.

In the above embodiment, the liquid drain port 4 is provided at the left end of the cleaning tank 1, but the position of the liquid drain port 4 can be changed depending on the side on which the collecting member 2 collects ink. .

Further, the driving device for moving the accumulating member 2 may be manually operated instead of being driven by a motor.

<Effects> As described above, according to the cleaning machine according to the present invention, the precipitated residue is easily accumulated on the bottom of the cleaning tank, and the accumulated residue is discharged, so that the residue does not reach the middle of the piping. It can be reliably discharged and removed to the outside of the cleaning tank without clogging. For example, if a wire bridging device is installed above the level of the cleaning liquid in the cleaning tank, it is possible to prevent the drive motor, wires, etc. from getting wet with the cleaning liquid.
