  However, the conventional brush device shown in FIG. 11 has a grip portion 105 extending substantially perpendicular to the paint supply body 100, and grips the grip portion 105 to perform a painting operation. An operator holding the wrist cannot sufficiently move the wrist in any direction including the up / down direction, the left / right direction, and the oblique direction with the wrist fixed.

  Therefore, in order to change the direction of the brush when painting the inner side or back side of the member, it is necessary to perform the painting work while moving the entire elbow and arm including the wrist. Was very bad, and there was a problem that the efficiency of painting work was lacking.

  In addition, since the gripping force lever 103 has a one-finger pulling or two-finger pulling structure, when the spring strength of the trigger is strong, there is a possibility that the operator may feel tired. there were.

  Furthermore, the conventional brush apparatus is configured such that, when the painting operation is interrupted, the coating material hardens inside the coating material supply body, and the coating material supply body is clogged. There was also a situation where they could not be sent.

  In addition, many of the current paints generally use double-mixed paints in which a solution called a main agent and a curing agent are mixed and used because of their anticorrosive properties. The chemical reaction is started and cured by mixing and stirring the main agent and the curing agent. Therefore, once the main agent and the curing agent are mixed, there is a restriction on the usable time, so it is important to stir and mix only the required amount immediately before applying the paint. In reality, the apparatus does not take into consideration such a point.

  Therefore, the present invention was created in view of the existing circumstances as described above, and in an operator who has a paint supply body with a brush attached to the tip, in the vertical direction, the horizontal direction, or the diagonal direction. Fully move the wrist back in all directions, including the above, and apply the brush to the inner and rear sides of the member without difficulty to perform efficient painting work. Provided an automatic paint supply type brush device that can operate the lever with less feeling of fatigue when discharging into the brush, and prevents the remaining paint from hardening inside the paint supply body. The purpose is to reduce waste.

The present invention relates to an automatic paint supply type brush apparatus including a paint supply body that discharges pressurized paint from a nozzle disposed inside a brush and supplies the paint to the entire brush from the inside of the brush.
Attach a brush to the tip of the paint supply body at an angle of about 5 ° to 45 °,
The coating material supply body is configured such that the nozzle is removed from the supply pipe portion by a pressing operation of a push-down lever that is supported at one end so as to face the front nozzle side and swingable with respect to the coating material supply body. Equipped with a paint jetting mechanism that feeds paint into
Hold the paint supply body with your thumb, middle finger, and index finger so that the base end is on the back of the hand so that you can freely change the direction of the brush by turning your wrist back, and press the push lever with your index finger. ,
The paint jetting mechanism includes a front cylinder disposed at the front and back through an open part recessed to dispose the push-down lever at a substantially center of a paint supply body arranged above a supply pipe part for feeding paint to the nozzle, and The rear cylinder and the front opening of the supply pipe are in communication with the front cylinder, and the needle valve is arranged so as to be slidable in the front-rear direction within the front cylinder, and the rear end opening facing the open side of the front cylinder. A packing screw sealed in a state in which the needle valve is slidably inserted, a needle spring disposed in the rear cylinder, and a front cylinder leading to the nozzle are provided at the tip of the front cylinder so as to be always closed via the needle spring. An opening-shaped valve seat that is urged, a plunger that is fitted into the rear end of the needle valve, and a paint adjustment screw that is attached to the rear end of the rear cylinder And parts, the formed,
The plunger is inserted into the rear cylinder from the open side, and the needle spring is disposed between the paint adjusting screw portion at the rear end and the plunger, and the plunger is expanded by the pressure expansion elastic force of the needle spring. Always energized forward with the needle valve,
The push-type lever is pivotally mounted in the opening portion so as to be swingable via a support pin so as to face the front nozzle side, and is extended downward from the position of the support pin. However, the problem mentioned above was solved by contact | abutting to the said plunger which has inserted the needle spring .

  Moreover, the problem mentioned above was solved by attaching the brush at an angle of about 30 ° to the tip of the paint supply body.

  Furthermore, the problem mentioned above was solved because the attachment angle of the brush with respect to the coating material supply body is adjustable.

Moreover, the problem mentioned above was solved by providing the supply pipe part with a plurality of hose connection pipes .

  In addition, the problem mentioned above was solved by providing two hose connection pipes in the supply pipe part.

  Moreover, the one above-mentioned subject was similarly solved because one hose connection pipe is arrange | positioned linearly with respect to a supply pipe part.

  In addition, the other hose connecting pipe is arranged in a crossing manner with respect to the supply pipe portion, thereby solving the above-described problem.

  Moreover, the supply pipe part is provided with a stirring tank containing a mixing blade, thereby solving the above-described problem.

  Furthermore, the above-mentioned problem was solved by connecting two paint supply hoses for feeding paints of different colors to the supply pipe section.

  Moreover, the problem mentioned above was solved by connecting the paint supply hose and the solvent supply hose for washing to the supply pipe part.

  According to the present invention, in an automatic paint supply type brush device that discharges pressurized paint from a nozzle disposed inside a brush and supplies the paint to the entire brush from the inside of the brush, Since the brush is attached to the tip portion at an angle of about 5 ° to 45 °, and preferably about 30 °, among these, the operator freely moves the wrist in the operator holding the paint supply body. It is possible to perform efficient painting work by applying the brush to the inner side and back side of the member with sufficient motion to return the wrist in all directions including vertical direction, horizontal direction, diagonal direction etc. It can be carried out.

  Therefore, according to the present invention, in order to change the direction of the brush when painting the inner side surface and the back side surface of the member, the painting work was performed while largely moving the elbow and the arm including the wrist each time. Compared with a conventional brush apparatus, the efficiency of the painting work can be dramatically improved.

  Moreover, since the attachment angle of the brush with respect to the paint supply body can be adjusted, the preferred attachment angle of the brush to the paint supply body can be appropriately selected according to the position and angle of the member to be painted, and the paint supply An operator holding the body can freely move the wrist, fully move the wrist back in all directions including vertical direction, left and right direction, diagonal direction, etc. Efficient painting work can be performed by applying the brush to the back side without difficulty.

  Furthermore, since the paint supply body includes a supply pipe portion that feeds the paint to the nozzle, and the supply pipe portion is provided with a plurality of (for example, two) hose connection pipes, A paint supply hose that feeds red (white) paint is connected, and a paint supply hose that feeds white (red) paint is connected to the other hose connection pipe. A painting operation using a color paint can be performed.

  In addition, since one of the hose connection pipes is arranged in a straight line with respect to the supply pipe part, the supply pipe part and the hose connection pipe are almost integrated to realize a downsizing of the paint supply body. The painting work is made easy.

  In addition, since the other hose connection pipe is arranged so as to intersect with the supply pipe section, the two hose connection pipes overlap in the vertical direction, and the whole is not bulky. The work is made easy.

  In addition, when a paint supply hose is connected to one hose connection pipe and a solvent supply hose for cleaning is connected to the other hose connection pipe, the paint will remain inside the paint supply body when the painting operation is interrupted. Even when it is cured, the solvent can be sent to the coating material supply body, the cured coating material can be dissolved, and the painting operation can be resumed immediately. Further, the solvent can be fed into the paint supply body and the paint supply hose connected thereto, and the paint supply hose can be easily cleaned.

  In addition, by sending a solvent to the paint supply body at the end of the painting operation, it is possible to prevent the paint from being cured inside the paint supply body or the brush.

  And since the supply pipe | tube part is equipped with the stirring tank which incorporated the blade body for mixing, when two types of paints from which a color differs are sent into the supply pipe | tube part, for example, each coating material is a mixing blade | wing. By passing through the agitation tank while in contact with the body, the two color paints are immediately agitated to form a mixed state without any spots, and the mixed paint can be discharged from the nozzle.

  Furthermore, the automatic paint supply brush device according to the present invention is compatible with a change in the paint used (change from a paint using an organic solvent to a water-soluble paint not using an organic solvent).

  That is, in the current paints, paints (mixed liquid mixture type paints) in which a plurality of types of liquids are mixed and used are mainly used due to their anticorrosive performance. At this time, for example, when two kinds of solutions are mixed, a chemical reaction starts, and particularly in summer when the temperature is high, these mixed paints are hardened in a very short time. Therefore, in such a multi-liquid mixed type paint, it is desirable to mix just before applying a necessary amount of paint.

  Specifically, many of the current multi-component mixed paints are mainly made of two-components that use the main agent and the curing agent with stirring because of their anticorrosive properties.

  The paint is agitated and mixed with the main agent and the curing agent to start a chemical reaction and harden.

  Therefore, when the main agent and the curing agent are mixed while being stirred, the usable time is restricted. In other words, the paint does not cure unless the main agent and the curing agent are mixed. Therefore, in order to use it efficiently, it is wasteful to stir and mix only the required amount immediately before applying the paint. Will not.

  The paint automatic supply type coating device according to the present invention has a function of feeding the main agent and the curing agent separately and mixing them in a stirring tank. Therefore, when two kinds of paints are fed, each paint passes through the stirring tank while being in contact with the mixing blade, so that the paint is forcibly and complicatedly mixed in a very short time without any spots. A mixed state can be created.

  As a result, the occurrence of a situation where the paint is hardened by the chemical reaction when the two kinds of paints are mixed can be reliably prevented, and a smooth painting operation can be realized without wasting the paint. In particular, even when paint is sent through a long hose during work at high places such as a steel tower, the chemical reaction does not start in the process of feeding, and it is possible to prevent the paint from clumping in the hose. .

  That is, a smooth coating operation is realized by making the state of the paint when the two types of paint are mixed and the state of the paint when ejected from the nozzle exactly the same. Also, since the two types of paint are mixed and the paint is immediately discharged from the nozzle, a smooth painting operation is also realized in this respect.

  Furthermore, the paint supply body includes a paint ejection mechanism that feeds the paint to the nozzle by a pressing operation of a push-down lever that is pivotally supported at one end and is swingable with respect to the paint supply body. When the pressurized paint is discharged from the nozzle into the brush, the operator can operate the lever with less fatigue.

  In addition, since the paint supply body is gripped by the thumb, middle finger, and index finger so that the base end is located on the back side of the hand, it is possible for the operator holding the paint supply body to move the wrist freely. The direction of the brush can be changed freely by turning the wrist back in any direction including the vertical direction, the horizontal direction, and the diagonal direction. be able to.
