The prime mover 50 and the motor unit 55 operate in cooperation with the first and second valve bodies 20A and 20B, thereby enabling the removal of the remaining top and curing agent described later.

The conventional first and second valve bodies are not limited to the above-described prior arts. The first and second valve bodies may include a prime mover unit 50 and a motor unit 55 for various types of valve bodies using a piston and a valve pin The related configurations including the above are applicable.

Hereinafter, each component will be described in detail. For the sake of convenience of explanation, other configurations other than the core configuration of the present invention will be described as an example of the configurations of the prior arts, but they can be implemented as various types of devices.

That is, the structure in which the lifting and lowering motion of the piston in the housing 21 is controlled via the air hose 21a and the subject and the curing agent independently supply through the respective inflow pipes 24a are the same as those of the prior art. The first valve body 20A is connected to the first tank 41 by a hose and the first valve body 20A is connected to the main body of the paint supplied by the operation of the first pump 41a, To the inside of the first flow passage (10A) of the main body (10).

3 and 4, a protection unit according to an embodiment will be described. FIG. 3 is a perspective view illustrating a protection unit according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view illustrating a protection unit having a protection unit according to an embodiment.

Referring to FIG. 3 (a), the protective portion 60 is essentially provided with the side plate 61. The side plates 61 are located on both sides of the direction of travel of the vehicle and serve to block wind from the side surfaces of the side plates 61. The side plates 61 are formed to have a narrow gap between the side plates 61 do.

Accordingly, the inner space between the side plates 61 is formed to become narrower toward the running direction side and wider toward the opposite direction. As a result, the air inlet space 619 on the traveling direction side is relatively narrow while the air outlet space 615 on the opposite side is formed relatively wide. In this case, the direction from the front is moved through any one of the first path that flows along the inside of the protective portion 60 and the second path that flows along both sides of the protective portion 60. When a certain amount of wind is blown, when the wind is introduced through the air inlet space 619, the space is expanded to increase the pressure, so that the wind speed decelerates. As a result, the influence of the external wind is reduced, and the phenomenon that the injection path of the curing agent and the subject injected to the inside of the protection portion 60 is minimized is minimized.

On the other hand, the second side plate 611 can be provided at the front end portion of the side plate 61, that is, on the traveling direction side of the vehicle. The second side plate 611 is formed so that the distance between the side plate 61 and the side plate 61 is reduced. In other words, the distance between the second side plates 611 is reduced toward the running direction at a larger ratio than the width between the side plates 61. The second side plate 611 is provided to increase the pressure of the air at the first inflow point of the air introduced from the air inflow space 619 to increase the amount of decrease in the air speed.

The upper plate 611 fixes the side plates 61 therebetween. The upper plate 611 is fixed to the lower end of the branch body 10 directly or by using a separate member. The first nozzle 30A and the second nozzle 30B pass through the upper plate 611 and are positioned between the side plates 61 or between the first nozzle 30A and the second nozzle 30B A through hole (621) is formed through the through hole so as to form a path so that the sprayed subject and the curing agent can pass downward.

3 (b), a lower plate 613 connecting the side plates 61a is formed at the lower end of the plate 61a in the traveling direction side. The lower plate 613 may be formed to be inclined upward toward the traveling direction side. The lower plate 613 enlarges the inner space from the air inflow space 619 toward the inside, thereby greatly reducing the air velocity of the air introduced from the air inflow space 619.

On the other hand, the position of the protective portion 60 in the vertical direction or may be variously formed. For example, it is also possible that the upper end surface of the protecting portion 60 is directly positioned at the lower end of the first and second nozzles 30A and 30B as shown in Figs. 3 and 4, 30A) 30B so that the protective portion 60 can be attached to the lower end of the branch body 10. [0054] A separate member for connecting the protection unit 60 and the branch body 10 can be implemented in various ways, and a detailed description thereof will be omitted.

In addition, the vertical length of the protective portion 60 can be variously formed. The entirety of the injection path of the subject and the curing agent may be protected, or it may be formed to be shorter than this.

That is, it is essential that the protective portion 60 includes the path of the upper part of the injection route of the main body and the hardener. The length of the protective portion 60 in the vertical direction may be various have. When protecting the upper path from the external wind pressure in the course of the subject and hardener, the extent to which the wind has already formed is not changed enough.

With reference to Figs. 5 to 8, the related constitution including the valve body 20A and the branch body 10 according to the embodiment of the present invention will be described. FIG. 5 is a cross-sectional view showing a two-part type vehicle paint painting apparatus according to an embodiment, and FIGS. 6 to 8 are an exploded perspective view, a first state sectional view, and a second state sectional view showing a state of a valve body according to an embodiment .

The basic configuration and operation are similar to the above-described prior art.

Specifically, the configuration of the first and second nozzles 30A and 30B is as follows. The connection pipe 11 is coupled to the lower outlet of the first and second flow passages 10A and 10B and integrally fixed to the lower portion of the branch body 10 by welding, The nut 32 is inserted into the nut 31 and is supported by the washer.

The first and second nozzles 30A and 30B are installed close to each other in the lower portion of the distributor 10 and the first and second nozzles 30A and 30B are mounted with an inner inclination, The nozzle 2 is configured such that the nozzle 2 is mixed with the curing agent sprayed through the nozzles 30A and 30B to paint the lane 2 on the road 1.

The first and second valve bodies 20A and 20B and the first and second flow passages 10A and 10B are injected through the first and second nozzles 30A and 30B, And the lane 2 is formed on the road 1.

The first valve body 20A and the second valve body 20B open and close the internal flow path by the operation of the valve pin 23 that is raised and lowered by the operation of the pneumatic cylinder to intermittently As shown in Fig. The first and second valve bodies 20A and 20B are formed in the same structure. That is, the piston 22 inserted into the housing 21 of the cylinder is lowered by the elastic force of the spring 22a mounted on the upper portion, and the air introduced through the air hose 21a connected to the lower portion of the housing 21 The cemented carbide interrupter pipe 25 is coupled to the inside of the valve tube 24 mounted on the lower portion of the housing 21 and the valve pin 24 coupled to the rod of the piston 22 When the fluid flows through the inflow pipe 24a coupled to one side of the valve tube 24, the lower ball 23a of the valve pin 23 is opened and closed, And the spiral portion formed on the valve tube 24 is screwed to the spiral portion formed on the inlet side of the first and second flow passages 10A and 10B so as to be discharged through the intermittent pipe 25, It is a structure to be combined.

The two-liquid paint lane painting apparatus according to the present invention differs from the construction of the piston rod 221, the valve pin 23, the follower motor unit 223, the prime mover unit 50 and the motor unit 55 in particular.

The piston rod 221 has a vertical control pipe 226 formed in a hollow shape from the lower end and connected to the through hole 239 of the valve pin 23 and a vertical control pipe 226 radially extending from the upper portion of the vertical control pipe 226 toward the outer peripheral surface At least one connection control tube 225 is formed. The piston rod 221 is exposed to the lower portion of the housing 21 at the lower end of the piston 22 when the piston 22 is lowered as shown in FIG.

A valve pin (23) is connected to a lower portion of the piston rod (221). The valve pin (23) is provided with a through hole (239) penetrating in the central axis direction. As described above, the ball 23a at the lower end of the piston rod 221 closes the intermittent pipe 25 when the piston 22 is lowered. In this case, the through hole 239 of the valve pin 23 is connected to the intermittent pipe (25).

A vertical control pipe 226 is formed upward from the lower end center of the piston rod 221 and a connection control pipe 225 is formed radially from the upper end of the vertical control pipe 226.

The prime mover part (50) rotates in engagement with the longitudinal synchronizer (223) when exposed to the follower synchronizer (223). At this time, the motor section 55 provides rotational force to the prime mover section 50.

On the other hand, the branch pipe 217 is formed as a channel through which air is supplied to the branch body 10. At this time, the branch pipe 217 may be formed in the form of a pipe branched from the air supply pipe 21a. When the piston 22 is lifted, the branch pipe 217 is separated from the connection control pipe 225 and is closed. When the piston 22 is lowered, And is opened / closed through a process of being communicated with or separated from the connection control pipe 225.

On the other hand, a follower synchronizer 230 is formed at the lower end of the piston rod 221. The maximum outer diameter of the follower female part 223 is formed to be smaller than or equal to the outer diameter of the piston rod 221.

Further, the motor unit 55 can control the position and rotation of the rotation phase of the connection control pipe 225 using a step motor or the like. The piston rod 225 is rotated by the motor unit 55 so that the air supplied through the branch pipe 217 can be continuously or discontinuously transmitted to the interrupting pipe 25 through the valve pin 23 . For example, when the piston rod rotates in a descending state, air supplied from the branch pipe 217 is supplied to the lower end of the intermittent pipe 25 in a point-by-point manner in which supply and interception are repeated, When the branch pipe 217 and the vertical control pipe 225 are controlled to communicate with each other, the air is continuously supplied to the lower side through the interrupting pipe 25. The air supplied in this manner can act to efficiently remove the subject or curing agent remaining in the first and second flow paths 10A, 10B.

A downward restricting portion 218 is formed on the inner circumferential surface of the housing 21 so as to protrude in the direction of the central axis to limit the maximum lowering position of the piston 22. The connection control pipe 225 can be positioned so as to be able to communicate with the branch pipe 217 by rotating the piston rod 221 when the piston 218 contacts the downward restricting portion 218. [ Further, a packing portion 219 may be provided on the upper portion of the lowering restricting portion 218. The packing portion 219 serves to reduce the friction with the downward restricting portion 218 when the piston 22 rotates.
