Description

Detailed Description of the Invention (a) Technical Field The present invention relates to a brush cleaning device, and more specifically, to a brush cleaning device for brushes such as painting brushes, roller brushes, and glue brushes for applying coating liquids such as paints and glues. The present invention relates to a brush cleaning device that washes away coating liquid adhering to the brush after use.

(b) Prior art If the used brush is left unattended after painting, etc., the paint remaining on the brush will harden and become unusable. Each bottle was cleaned by hand using a solvent or special cleaning solution placed in an empty paint can or a special cleaning container. However,
Apart from so-called home painting, which is done as a hobby, painting companies have had to carry out this troublesome cleaning work every day after finishing the painting work, which has become a source of trouble for them. In general, personnel costs (labor wages)
There is a tendency to increase, and the labor costs required for the above-mentioned cleaning work are also rising considerably. For example, 30 painting workers (craftsmen) each use one brush and work for 24 days/
Assuming an hourly wage of 1,500 yen per month and 30 minutes of brush cleaning time, labor costs will increase to approximately 540,000 yen per month. In addition, in recent years, with changes in society and economy, workers' awareness of labor has changed, and for example, in painting work,
There is a growing tendency for people to avoid non-essential cleaning work after work is completed. For these reasons, people have come to think that it is unavoidable to stop reusing the brushes, make them disposable, and reduce or eliminate the cleaning work as much as possible. However, in this case, it goes without saying that the cost of brushes that are provided every day is required. Of course, there are differences depending on the scale of the object to be painted and the physical/chemical conditions, etc., but for example, as above, some of the 30 craftsmen reuse brushes during a 24-day workday per month. Even so, 10 to 15 brushes must be provided per day, and assuming that the price of a standard brush is around 4,000 yen, the monthly cost is 960,000 yen to 144 yen.
It will cost about 10,000 yen.

In addition to the economical issues such as the above-mentioned costs, it also helps to improve the quality of the painting, as the more a brush is reused, the more the bristles become even, and the more it blends into the painted surface, the more beautiful the paint finish becomes. It is preferable to reuse the brush.

Furthermore, in the above-mentioned cleaning work for home painting, there was a fear that an inexperienced amateur could cause an accident such as splashing the cleaning liquid or solvent from the container and getting it into the eye.

In addition, in order to return a fixed brush to a state where it can be used again, conventionally, it is necessary to simply soak it in a solvent, etc.
There is no other way than to leave it until it softens and wait, and although it varies depending on the degree of solidification mentioned above, the size of the brush, the nature of the liquid being applied, etc., it takes a much longer time than cleaning it before it dries (hardens). I had the problem of needing it.

(c) Purpose The present invention was made in view of the above circumstances, and
The purpose is to reliably and quickly wash away the liquid to be coated on the brush by simply attaching the brush to the cleaning device and at least starting the cleaning device, allowing the brush to be reused. Reduces the purchase cost and cleaning cost of motsubrush,
Further, it is an object of the present invention to provide a brush cleaning device that can make the finish of painting, etc. more beautiful.

(d) Structure In order to achieve the above-mentioned object, the present invention provides a method for applying coating liquids such as paint and glue after using a brush such as a painting brush, a roller brush, or a glue brush. In the brush cleaning device for washing off the liquid to be coated which has been applied, a cleaning liquid storage part is provided in a lower part in which a cleaning liquid for cleaning the liquid to be applied adhering to the brush is stored, and a handle part of the brush is set up in the upper part. a cleaning chamber provided with a space for cleaning, a drive section having a motor for rotationally driving a drive shaft partially facing the top of the cleaning chamber, a control section for controlling rotation of the motor, and a drive section fixed to the drive shaft for controlling the rotation of the motor; , a brush mounting part that holds the handle part in a suspended manner, and the brush is mounted at a height position where the brush part to which the liquid to be applied is immersed in the cleaning liquid in the cleaning liquid storage part.

Although the configuration of the operation panel 48 is not shown,
It is assumed that this embodiment is almost the same as the first embodiment. However, the third
The rotation direction indicator lights 27 and 28 in the figure are omitted, the speed switching knob 5 and the knob display 26 are moved as a pair to the right and left ends in the figure, and a display window 49 is provided in the center.
A hole is drilled through which it is inserted. Further, the main parts of the circuit section (not shown) are substantially the same as those of the first embodiment.

6 is a partially cutaway side view showing the vicinity of the adapter 50 of FIG. 5. FIG. Incidentally, the same members as those in FIG. 5 are given the same numbers and redundant explanations will be omitted.

In the same figure, 61 and 62 are bent pieces, respectively, and 61a is a shaft hole drilled in the holding substrate 51, which is connected with a pin to the shaft hole drilled at the tips of both the bent pieces 61 and 62. They are connected to form the holding portion 60.

Although not shown, a spring (not shown) is placed between the clamping substrate 51 and the movable clamping plates 58 and 59, so that the clamping parts 58b and 59b are biased toward each other. It is assumed that 6
3 is a human hand, 63a and 63b are a thumb and an index finger, respectively, and 64 is a hole in the brush 52.

The operating procedure of this embodiment configured as described above will be explained. First, a first embodiment shown in FIGS. 1 to 4 will be described. However, it is assumed that the container 10 is already installed in the cleaning chamber 1 with the fixing fittings 10a.

Further, it is assumed that the speed switching knob 5 in FIG. 3 is in the "OFF" position of the knob display 26, and the end switch 35 is in the reset state (closed). First, unlock the locks 18 and 19, open the door 15 (as shown in the first figure), and open the solvent injection line 1.
7 as a guide, and inject the cleaning liquid 11 up to the liquid level 11a. Next, hold between the gripping part 8c and the back side of the clamping board 7 (the back side of the page) with your fingers, and
The holding portion 9 is expanded so that d and 8d are separated.
Then, holding the brush 12 with the other hand, once push the brush part 12c to the bottom of the container 10,
The handle 12a of the brush 12 is inserted into the expanded opening, and the locking pin 7c is inserted into the hole 12b to stop the gripping. As a result, the movable clamping plate 8, whose gripping force has been released, tries to return to its original state due to the biasing force of a spring (not shown), and the intermediate part of the brush 12 is clamped between the clamping parts 7d and 8b. 9 (the state shown in the first diagram). Next, the door 15 is closed and locked using the snap locks 18 and 19.

Next, moving to the operation panel 4 in FIG. 3, the display changeover switch 33 is switched to, for example, the end time display, and the end time set button 29 is pressed (operated). The operator then visually observes the displayed value on the display 32, which is being updated sequentially, and releases the end time set button 29 (stops the operation) when the desired set value is reached. Next, the display changeover switch 33 is switched to the inversion cycle display, and the desired inversion cycle is similarly set by operating the inversion cycle set button 30. In this example, the end time is set to 30 minutes as shown in the third diagram, and the reversal period is set to 1 minute.

Next, the rotation speed of the brush 12 is determined in consideration of the amount of paint remaining on the brush portion 12c, the degree of dryness, the size of the brush portion, and the like. In this example, high speed rotation is selected, and the speed selector knob is turned from the "OFF" position.
Turn it to the "H" position as shown. From this point on, the pilot lamp 25 lights up, the motor 12 starts rotating, and the output shaft 3 starts rotating at a high speed via the gear section 22. That is, the brush 12 held by the holding part 9 rotates, and the remaining paint on the brush part 12c is automatically cleaned with the cleaning liquid 11.

Now, to explain the operation of this embodiment which started operation in this way, in FIG.
5 is closed as described above, and the speed selector switch 3
6 is connected to the H terminal. Reversing switch 3
7 and 38 are connected to the normal rotation terminals 37b and 38b, the motor 21 receives power from the battery 34 and rotates in the normal direction. If this forward rotation corresponds to clockwise rotation of the output shaft 3, the rotation direction indicator light 27 starts blinking at a period corresponding to the rotation speed. When the reversal timer 43 reaches the set value of 1 minute, the reversal switches 37 and 38 are switched to reverse the motor 21. And rotation direction indicator light 2
The blinking number 7 moves to 28. In other words, the brush 12 also changes from normal rotation to reverse rotation. Furthermore, when one minute has passed, the rotation is switched to normal rotation again and the rotation direction indicator light 27 is blinked.
Thereafter, this automatic reversal operation is repeated. On the other hand, when the set value of 30 minutes has elapsed, the end timer 41 opens the end switch 35 to turn off and maintains this state. At this point, the rotation direction indicator lights 27 and 28 stop flashing, and both become off.
The motor 21 is turned off by the termination switch 3 mentioned above.
5, the power will be cut off and it will automatically stop. The operator knows that the cleaning has been completed by turning off the light.

Next, return the speed selector knob 5 to "OFF" and press the reset button 31. The end timer 41 is
Upon receiving an input from the reset button 31 at the reset input terminal 40, the end switch 35 is closed and the pilot lamp 25 is turned off. By turning off the light, the operator knows that the device is ready to start the next operation.

Next, the operator opens the door 15 in the same manner as described above, takes out the brush 12 by performing the opposite operation to that described above, and replaces any unwashed brushes, if any. Further, if the cleaning liquid 11 overflows from the container 10 during the above-mentioned cleaning operation, the drain tank 14 is opened and the cleaning liquid 11 is discharged from the cleaning chamber 1 to the outside.

Next, the operating procedure of the second embodiment shown in FIGS. 5 and 6 will be briefly explained.

The locks 55 and 56 are unlocked, the control/mechanism section 44 is lifted upward by the handle 57, and the cleaning liquid 54 is injected into the cleaning chamber 45. Next, as shown in FIG.
9a is pinched and pressed between the thumb 63a and the index finger 63a, the gripping parts 58b and 59b move away from each other, and the gripping part 60 is expanded. By this expansion, the handles 52a and 53a of the brushes 52 and 53 are inserted into the openings created between the gripping parts 51a and 59b and between the gripping parts 51b and 58b, and further, The locking pins 51c and 51d are inserted into the holes 64 and 53c, respectively, and the pressing is stopped. In this way, the two brushes 52 and 53 are
0, the fitting portion 44a shown in FIG. 5 is fitted into the inner periphery of the upper end of the cleaning chamber 1, and the snap locks 55, 56 are locked.

The operation is almost the same as that of the first embodiment, so a description thereof will be omitted. Since the rotation state indicator 47 is directly connected to the output shaft, the operator can know the rotation direction and rotation speed of the brushes 52 and 53. Furthermore, the completion of cleaning can be known by the rotation of the rotation status indicator 47 being stopped.

As described above, according to the present embodiment, as in the first embodiment, an unwashed brush 12 is attached to the clamping portion 9 directly connected to the output shaft 3 using the motor 21 as the driving force, and the paint on the brush 12 is The remaining brush portion 12c is rotated in the cleaning liquid 11, and is cleaned while being automatically reversed, and the rotation is automatically stopped when a set scheduled time elapses, so the brush 12 can be removed with a simple operation. It can be attached to the holding part 9, and once it is attached, there is no need to monitor it and it can be left alone, which saves time and effort.Compared to the past, the cost of purchasing brushes and brushes is reduced as the brushes are not disposable. Labor costs for cleaning can be reduced.

Furthermore, since the brush 12 can be reused after cleaning, the use of a brush with well-aligned bristles that has been used for a long time provides a beautiful finish for painting, and the resulting effect is that the quality of the painting can be further improved.

Further, since the brush is rotated in the cleaning liquid 11, even when regenerating a brush that has already hardened, there is an advantage that the time can be shortened compared to the conventional method of simply soaking the brush.

Further, since the handle 6 and the hanging metal fitting 6a are provided, it is easy to carry, and the door 15 is attached with a sealing material 16, and the locks 18, 1 are attached.
Since the cleaning liquid 11 is locked at 9, the cleaning liquid 11 does not leak out of the cleaning chamber 1, and for example, cleaning can be continued even during movement, and accidents such as the cleaning liquid 11 being splashed and getting into the eyes of the worker can be prevented. There is.

In addition, the container 10 can be used to reuse empty cans of paint or other materials, so there are advantages in terms of effective use of resources and economy.

Furthermore, since the solvent injection line 17 is provided, the amount of cleaning liquid to be injected, which varies depending on the size of the brush 12, can be determined appropriately, and there is an advantage that unnecessary troubles such as overfilling or underfilling can be avoided. .

Furthermore, since the drain tank 14 is provided, not only can the cleaning liquid 11 overflowing into the cleaning chamber 1 be easily drained to the outside, but also a separate container can be placed inside the leg part 13, that is, below the drain tank 14. For example, there is an advantage that the overflowing cleaning liquid 11 can be easily recovered.

Further, since the rotation direction indicator lights 27 and 28 are provided, there is an advantage that the operation (rotation) state of the brush 12 can be recognized at a glance.

Further, since the control/mechanism section 2 has a so-called explosion-proof structure, there is an advantage that there is no risk of the cleaning liquid such as thinner catching fire.

In addition, since the configuration uses the battery 34 as a power source,
This device has the advantage that it can be used even in places where there is no commercial power supply.

Furthermore, as a second embodiment, a clamping board 51 is connected in the axial direction from an adapter 50 connected to an output shaft, and a clamping part 60 is provided with movable clamping plates disposed on both sides with the clamping board 51 sandwiched therebetween. Since I configured
There is an advantage that a plurality of (two) brushes 52, 53 can be washed at the same time, and furthermore, it is possible to save labor in the washing work.

Further, in the second embodiment, since a part of the cleaning chamber 45 is also used as a container, there is an advantage that the trouble of installing the container can be saved.

Further, since the mechanical rotational state indicator 47 is provided, there is an advantage that the rotational state of the brushes 52, 53 can be easily understood intuitively.

Further, since the control/mechanism section 44 and the cleaning chamber 45 are divided into two vertically, there is an advantage that the brushes 52 and 53 can be attached and detached even if there is no space around the cleaning chamber 45.

It should be noted that the present invention is not limited to the above-described embodiments, and can be modified in various ways without departing from the spirit thereof.

For example, the end of the cleaning operation may be notified by a sound such as a buzzer.

Further, both timers 41 and 43 are not limited to electronic types, and may be electric types.

The speed changeover switch 36 is not just a rotary switch, but is always biased by a spring toward the "OFF" position, that is, in the counterclockwise direction in FIG. If it is set to "H", this "H"
It may be configured so that the lock is released when the end timer 41 reaches the set value. In this case, the speed changeover switch 36 automatically returns to the "OFF" position. The end switch 35 and reset button 30 can be omitted.

In addition, in FIG. 4, by connecting a reverse current prevention diode 65 to the positive electrode of the battery 34 in the forward direction, the output of the rectifier circuit 66 is connected in parallel with the battery 34, and the AC input terminal 67 is connected to the rectifier circuit. A configuration connected to the input end of the 66 may be added, and in this case, not only a battery power source but also an AC power source, such as a commercial power source, etc. can be used, and there is an advantage that it can be used more widely. Further, the battery 34 may be a dry cell, a rechargeable battery, or even an automobile power storage device.

Furthermore, the speed control may be performed by so-called chopper control that controls the time period during which the motor 21 is energized, instead of using the speed control resistors R1 to R3.

For example, T1, T2, and T3 in FIG. 7 are motors 21 that control high speed, medium speed, and low speed, respectively.
The energization waveforms are shown as “H” and “H” in Fig. 3, respectively.
It may be configured to correspond to "M" and "L".
In this case, there are advantages that the power consumed by the speed control resistors R1 to R3 is not wasted and that heat generation can be eliminated.

Further, the holding portion 9 may be configured to be slidable in the axial direction of the output shaft 3. In addition, when configured in this way, after cleaning, once the door 15 is opened,
By raising the brush 12 above the liquid level 11a while holding it between the clamping parts 9, closing the door again, and storing the brush 12, the drained (deliquid) brush part 12c is placed in the volatile atmosphere of the cleaning liquid 11. By being exposed to
There is an advantage that the brush portion 12c is soft and contains almost no cleaning liquid when used next time, and can be stored in a very easy-to-use condition.

Further, in the second embodiment, the adapter 50 and the output shaft may be configured to be detachable. in this case,
This has the advantage that the brushes 52, 53 can be more easily attached and detached.

Additionally, a small ventilation hole may be provided in the upper edge of the door 15.

Also, the brushes 12 attached to the clamping parts 9 and 60
