The rotating arm 20 is formed of a tube radially disposed about a drive shaft. The rotating arm 20 is arranged to be spaced apart from the upper portion of the leather, so that the paint can be sprayed on the leather while rotating 180 degrees to the left and right.

At this time, the driving unit 120 is in charge of rotation of the rotation arm 20. The drive unit 120 is connected to the axis of the rotary arm 20 by a chain or line, and when the drive unit 120 starts mechanical movement, the axis of the rotary arm 20 connected by a chain or line is also connected to the chain or line. As a result, rotation starts in engagement with the mechanical movement of the driving unit 120.

For example, referring to FIG. 5, the sensing unit 110 may include a module that recognizes the shape of the leather, and may transmit and receive the recognized data to the central control unit. When the shape of the leather to be sprayed is acquired and transmitted to the central control unit, the system controls the driving unit 120 according to the shape of the leather.

The driving unit 120 may receive energy from the system, and a motor that converts into mechanical motion may be mainly used, and the form of the supplied energy may be electricity, heat, pressure, elasticity, etc., but is not limited thereto.

As the rotating arm 20 is started to be controlled by the driving unit 120, high-pressure air (transport air, open air) is also started to be prepared inside the chamber unit 130, respectively. The chamber unit 130 is provided with a first air tube 131 and a second air tube 132.

The first air pipe can be prepared in a state in which transport air is supplied from the air tank 20 and mixed with paint to receive and store transport air for spraying paint, and the second air pipe is opened and closed from the air tank 20. It can be prepared in a state in which the opening/closing air that controls whether the spray unit 160 is turned on/off is received and stored.

The supply unit 140 is composed of a first supply unit 131 supplying transport air to the first air pipe 131 and a second supply unit 132 supplying opening and closing air to the second air pipe 132. In addition, the first supply unit 131 and the second supply unit 132 may receive high-pressure air (transport air, opening/closing air) from the air tank 20.

The fluid control module 150 needs to be controlled in order for the system to spray the paint onto the leather in a state in which the transport air and the paint are prepared inside the chamber unit 130. The fluid control module 150 may receive the open/close air of the air tank 20 from the second air pipe 132 and introduce the open/close air to the spray unit 160. On/off of the spray unit 160 receiving the opening/closing air from the fluid control module 150 may be determined. When the fluid control module 150 receives an electrical signal from the outside, the opening and closing air starts to flow into the spray unit 160 and the paint starts to be sprayed on the upper portion of the leather. If the electrical signal is released while the paint is being sprayed, the opening and closing air does not flow into the spray unit 160 and the entrance of the spray unit 160 is blocked, and the spraying of the paint is stopped.

The injection air control system having an air chamber function of a radial arm according to the present invention includes a chamber unit 130 and a supply unit 140, and a fluid control module 150 and a spray unit 160, as shown in FIG. ) Can be included.

Referring to FIG. 2, one chamber unit 130 may be formed of a plurality of independent tubes, and the chamber unit 130 of FIG. 2 is provided with a first air tube 131 and a second air tube 132. have. The supply unit 140 is composed of a first supply unit 131 supplying transport air to the first air pipe 131 and a second supply unit 132 supplying opening and closing air to the second air pipe 132. In addition, the first supply unit 131 and the second supply unit 132 may receive high-pressure air (transport air, opening/closing air) from the air tank 20.

The first air pipe 131 may receive and store transport air for spraying paint sprayed by mixing with the paint supplied to the spray unit 160.

The second air pipe 132 may accommodate and store open/close air that controls whether or not the spray unit 160 is turned on/off.

The fluid control module 150 is disposed between the second air pipe 132 and the spray unit 160 to manage the opening and closing air flowing into the spray unit 160 to manage the opening and closing of the inlet of the spray unit 160. I can.

When current flows in from the outside, an electromagnetic force is generated in the magnetic portion 152 inside the fluid control module 150, and the magnetic force between the magnetic portion 152 and the blocking portion 153 is attracted by the electromagnetic force generated in the magnetic portion 152. Will occur. The blocking part 153 rises in the direction of the magnetic part 152 where manpower is generated, so that the open/closed air may flow through the pipeline inside the fluid control module 150.

As the opening and closing air circulating in the pipeline flows into the spray unit 160, the pressure inside the spray unit 160 increases. When the pressure inside the spray unit 160 increases due to the introduced high-pressure opening and closing air, the needle elastic member 165 inside the spray unit 160 rises, and as the needle elastic member 165 rises, the flow plate ( 166 also rises, and the needle 163 connected by standing upright with the flow plate 166 rises, so that the inlet of the spray unit 160 may be opened.

When the inlet is opened and the transport air of the first air tube 131 is mixed with the paint and exits to the open inlet, the transport air mixed with the paint may be ejected and the paint may be sprayed onto the leather.

When current does not flow into the fluid control module 150, the opening and closing air no longer flows into the spray unit 160.

When no current flows into the fluid control module 150, the magnetic part 152 inside the fluid control module 150 no longer generates electromagnetic force.

When no electromagnetic force is generated in the magnetic portion 152, the elastic portion 154 is pressed downward by the elastic force, and the blocking portion 153 attached to the elastic portion 154 descends to close the pipeline. When the pipeline is closed, since the opening and closing air is no longer circulating from the outside, the opening and closing air cannot be supplied to the interior of the spray unit 160. If the opening/closing air does not flow into the spray unit 160, the pressure gradually decreases inside the spray unit 160. As a result, the flow plate 166 descends due to the nature of the needle elastic member 165 to return to its original state. Since the needle 163 coupled with the plate 166 also vertically descends downward, the needle 163 blocks the entrance of the nozzle 162 and the spraying of the paint is stopped.

In the spray air control system having the air chamber function of the radial arm according to the present invention, as shown in FIG. 3, the spray part 160 for controlling the spraying of paint by controlling the opening and closing air includes a spray body part 161, A nozzle 162, a needle 163, an air cap 164, a needle elastic member 165, a flow plate 166, and an entrance pipe 167 may be included.

Referring to the drawing (a) of FIG. 3, it can be seen that the paint is sprayed.

When opening/closing air flows into the entrance pipe 167 disposed below the flow plate 166 among one side of the spray body 161, the pressure inside the spray unit 160 increases. When the pressure inside the spray unit 160 increases, the needle elastic member 165 coupled with the spray body unit 161 starts to contract in the direction of the spray body unit 161. When the needle elastic member 165 contracts, the flow plate 166 fixedly attached to the lower end of the needle elastic member 165 also rises vertically. When the flow plate 166 rises vertically, the needle 163 that is vertically standing and fixed on the lower surface of the flow plate 166 also rises vertically, and the needle 163 blocking the inlet of the nozzle 162 By vertically rising, the inlet of the nozzle 162 can be opened.

As the transport air of the first air tube mixed with the paint in the spray unit 160 exits through the open inlet, the paint is sprayed on the upper portion of the leather.

Referring to the drawing (b) of FIG. 3, it can be seen that the injection of the paint is stopped by blocking the inlet of the nozzle 162 by the needle 163.

When opening and closing air does not flow into the entrance pipe 167 disposed under the flow plate 166 among one side of the spray body 161 and the air gradually begins to escape, the pressure inside the spray unit 160 gradually decreases. It is done. When the pressure inside the spray unit 160 decreases, the needle elastic member 165 coupled to the spray body unit 161 returns to its original state and starts to pressurize down.

When the needle elastic member 165 is pressed down and returned to its original state, the flow plate 166 fixedly attached to the lower end of the needle elastic member 165 is also vertically lowered. When the flow plate 166 descends vertically, the needle 163 that is vertically standing and fixed on the lower surface of the flow plate 166 also descends vertically, and the needle 163 that was opening the inlet of the nozzle 162 By vertically descending, the inlet of the nozzle 162 can be blocked.

The spraying of the paint may be stopped while the transport air of the first air pipe mixed with the paint from the inside of the spray unit 160 cannot escape to the blocked inlet.

In the injection air control system having the air chamber function of the radial arm according to the present invention, as shown in FIG. 4, the fluid control module 150 includes a module body part 151, a magnetic part 152, and a blocking part 153. ), may include an elastic portion 154 and a sealing portion 155.

Referring to the drawing (b) of FIG. 4, it can be seen that the blocking part 153 rises and the opening and closing air flows through the pipeline inside the fluid control module 150.

When current flows from the outside, the current flows into the fluid control module 150. Electromagnetic force is generated in the magnetic portion 152 inside the fluid control module 150 due to the current. An attractive force is generated between the magnetic portion 152 and the blocking portion 153 by the electromagnetic force generated by the magnetic portion 152. The blocking part 153 rises in the direction in which the manpower is generated, and thus, the opening and closing air may be circulated in the pipe passage inside the fluid control module 150 as it is opened to the pipe passage inside the fluid control module 150.

The opening/closing air circulating through the pipeline may be introduced into the spray unit 160 to control the on/off of the spray unit 160.

Conversely, if electromagnetic force is not generated in the magnetic portion 152 inside the fluid control module 150, the attractive force is not generated between the magnetic portion 152 and the blocking portion 153. If no attraction is generated, the elastic portion 154 attached to the module body portion 151 is vertically lowered, and the blocking portion 153 attached to the lower end of the elastic portion 154 is lowered. A sealing part 155 is attached to the lower part of the falling blocking part 153 to completely block the pipeline inside the fluid control module 150 to block the circulation of open/closed air, and open and close inside the spray part 160 Since air does not flow in, the inlet of the spray unit 160 is blocked, and the spraying of the paint is stopped.

In addition, the fluid control module 150 may be adjusted by adjusting the electrical signal.

When the opening/closing air circulated through the fluid control module 150 is controlled by controlling an electrical signal and the opening/closing air circulated in the second air pipe 132 is controlled to flow the adjusted opening/closing air into the spray unit 160, the spray unit (160) It is also possible to adjust the internal flow plate 166 and the needle 163 which is vertically standing and fixed to the lower surface of the flow plate 166. By controlling the movement of the needle 163, the spraying cross-sectional area of the paint can be adjusted, and when the pressure of the opening and closing air introduced from the second air pipe is adjusted, the paint sprayed from the spray unit 160 is sprayed in a straight line or diffused. Since it can be sprayed in a form, efficient and precise work can be possible.
