Accordingly, the slide block 151 is moved forward and backward by the first actuator 150 along the first guide rail 123. As the slide block 151 moves along the two first guide rails 123, the moving direction of the nozzle 120 may be maintained constant. If the slide block 151 has a non-uniform traveling direction, the nozzle 120 fixed to the slide block 151 also has a non-uniform traveling direction, so that the air is injected into the buffer packaging bag 1 positioned in the clamp 163. It is not inserted correctly into the conduit 3.

On the other hand, the nozzle 120 is a tubular structure having a length longer than the width and the hollow is formed, it is fixed in the state penetrating the slide block 151. A first coupler 121 for connecting a hose is fixed to the rear end of the nozzle 120 extending backward of the slide block 151, and the tip of the nozzle 120 is positioned toward the clamp 163.

On the other hand, the nozzle 120 penetrates the fixing block 130 and extends from the slide block 151 toward the clamp 163 and passes through the stopper 140 located in front of the fixing block 130.

The stopper 140 is fixed to the front end of the second guide rail 142, the second guide rail 142 is located through the fixing block 130. And the screw 143 is fastened to the side of the fixing block 130 to press the second guide rail 142, the second guide rail 142 is free to move in the longitudinal direction in the state in which the screw 143 is released. However, when the screw 143 is fastened, the movement of the second guide rail 142 is fixed. Therefore, the stopper 140 fixed to the front end of the second guide rail 142 is determined according to the fixed position of the second guide rail 142.

Meanwhile, the clamp 163 is mounted at the front end of the first lever 161 and moves downward to press the fixed block 130 according to the turning of the first lever 161 or moves upward to the fixed block 130. Falls from.

More specifically, the fixing block 130 is fixed to the first base 165 at a position corresponding to the clamp 163, the groove in the width direction so that the nozzle 120 passes through the bottom of the clamp 163 163h is formed.

In addition, the heater 173 is mounted at the front end of the second lever 172 and moves downward to press the second support 175 fixed to the fixing block 130 according to the turning of the second lever 172. Move to and fall off the fixed block (130). In the state where the air injection is completed in the buffer packaging bag (1), the heater 173 pivots downward to seal the inlet of the air inlet pipe (3) located on the second support (175).

Meanwhile, a wire is connected to the heater 173 to heat the heater 173, and the wire is connected to a power supply unit 180 mounted at the rear of the main body 110. The power supply unit 180 generates heat from the heater 173 by supplying external power to the heater 173.

On the other hand, as shown in Figures 7 to 9, the suction module 200 is the suction pad 210 and the suction port (Suction port 210) for sucking the air in order to suck and fix the two vinyl sheets (3v) of the air injection pipe (3) It is connected to the 220, the air is sucked through the suction pad 210 and the suction port 220 toward the suction module.

More specifically, the suction pad 210 is mounted in the groove 163h of the clamp 163, and the suction pad 210 is formed to suck air through the suction port 211. In addition, an adsorption port 220 is formed in the first pedestal 165. The suction port 220 formed in the suction port 211 and the first pedestal 165 of the suction pad 210 is connected to the suction module 200, and when the suction module 200 is operated, air is respectively suction port 211 and the suction port 211. Suction through the suction port (220).

Therefore, when the suction module 200 is operated while the air inlet pipe 3 is positioned between the clamp 163 and the first support 165, the upper part of the upper and lower vinyl sheets 3v forming the air inlet pipe 3 are formed. The outer surface of the vinyl sheet is located in close contact with the adsorption pad 210, the outer surface of the vinyl sheet located at the bottom is attached to the first base 165, the adsorption port 220 is formed.

At this time, when the clamp 163 is operated, the upper vinyl sheet 3v attached to the clamp 163 moves upward, and the inlet of the air injection pipe 3 opens. In such a structure, the suction port 211 and the suction port 220 formed on the suction pad 210 do not correspond to each other. The reason is that the suction port 211 and the suction port 220 are located correspondingly, and the attached vinyl sheet 3v may fall by mutual suction force.

Meanwhile, as shown in FIG. 10, the rear surface of the main body 110 includes a connector 181, which is a component of the power supply unit 180, and compressed air blown from the compressor so that an external power cable is connected. A second coupler 182 connected to an end of the hose and a third coupler 183 connected to an end of the hose for supplying air to the actuators 150, 160, and 170 and the suction module 200 are mounted to be blown.

And the control unit 190 for controlling the operation of the air injection device according to the invention is configured as shown in FIG.

As shown in FIG. 11, the control unit 190 presses the pressure gauge 191 indicating the pressure of the air blowing through the nozzle 120 and the time for pressing the inlet of the air injection pipe line 3 to the heater 173. Timer 193 for setting a, a start button 195 for inputting a signal to operate the main body 110 once, and a reset button 197 for resetting the function of the controller 190.

The following describes the operation relationship of the air injection device configured as described above.

First, the operator dismantles the angle adjusting bolt 115 from the female threaded hole 107 of the hinge bracket 103, and then tilts or maintains the main body 110 to its height, and then the angle adjusting bolt 115 ) Is inserted into any one of the angle adjusting holes 114 and fastened to the female screw hole 107. As such, the body 110 is tilted or leveled so that the operator can conveniently inflate the air.

Then, the screw 143 is released to set the position of the stopper 140 and fix the position of the stopper 140. At this time, the stopper 140 is set in consideration of the size of the buffer packaging bag (1).

After adjusting the inclination of the main body 110 and the position of the stopper 140 to be convenient for the worker to work in this way, the operator grips the buffer bag (1) and the air inlet pipe (3) and the nozzle 120 and It is located to correspond.

When a signal is input through the start button 195 of the controller 190, the compressed air is supplied to the second actuator 160 and the suction module 200 is supplied by the compressed air supplied while the second actuator 160 operates. ) Works. Then, the air is sucked through the suction port 211 and the suction port 220 of the suction pad 210, and the clamp 163 is moved downward toward the first support 165 by the second actuator 160. At this time, the lower vinyl sheet of the air inlet pipe 3 placed on the first support 165 is fixed to the adsorption port 220, and the upper vinyl sheet of the air inlet pipe 3 is adsorbed to the adsorption pad 210. It is fixed to the clamp 163 in a state.

In this state, the second actuator 160 is operated to move the clamp 163 upward. Then, the upper and lower two vinyl sheets 3v of the air injection pipe 3 are opened.

Next, the air blown from the compressor flows into the nozzle 120 and is discharged through the nozzle 120 into the air injection pipe 3 located at the front, and the air injection pipe path 3 formed by stacking two sheets of vinyl 3v. ) Is opened by the discharged air.

And while the first actuator 150 operates, the slide block 151 is pushed forward. Then, the nozzle 120 fixed to the slide block 151 is also advanced. Then, the air injection pipe path 3 is opened by the discharged compressed air, and the operator checks the nozzle 120 located forward and stops the buffer packaging bag 1 so that the nozzle 120 is inserted into the air injection pipe path 3. Push to 140.

In this state, the worker raises his hand from the start button 195 held down. Then, the controller 190 operates the second actuator 160. As the second actuator 160 is extended, the first lever 161 is pivoted and the clamp 163 fixed to the tip of the first lever 161 moves downward. The clamp 163 moved downward fixes the vinyl sheet 3v of the air injection pipe 3 while pressing the nozzle 120 inserted into the air injection pipe path 3. At this time, a groove 163h is formed in the clamp 163, and two sheets of vinyl sheet 3v are inserted into the clamp 163 and the first support 165 as the nozzle 120 is fitted into the groove 162h. The air injected into the conduit 3 is not leaked.

As the air flows into the air inlet pipe 3, the buffer packaging bag 1 expands, and the pressure is increased while the air is almost filled, and the inside of the buffer packaging bag 1 corresponds to the pressure value set in the controller 190. When the pressure increases, the controller 190 blocks the air injection.

When the air injection is blocked, the control unit 190 operates the third actuator 170, the power is supplied to the heater 173 before operating the third actuator 170, the heater 173 is the air injection pipe (3) The temperature of the vinyl sheets (3v) of the) to be thermally bonded to each other is maintained. When the third actuator 170 is operated while the heater 173 is heated, the second lever 172 is turned and the heater 173 mounted at the tip of the second lever 172 moves downward. Here, the nozzle 120 is located at a point that will not interfere with the heater 173.

On the other hand, while the heater 173 moves downward, the two sheets of vinyl sheet 3v held by the clamp 163 are thermally fused at the point where the heater 173 is in contact with each other, and the air injection pipe path 3 is caused by the thermal fusion. The inlet of is sealed. Here, the time for the heater 173 to press the two sheets of vinyl 3v is set by the timer 193 of the controller 190.

As the inlet of the air injection pipe passage 3 is closed in this way, the air injected into the buffer packaging bag 1 does not leak, even if the air of the buffer packaging bag 1 leaks and is filled in the air injection pipe passage 3. By increasing the internal pressure of the air injection pipe (3), not only suppresses the air discharge of the air column, the expanded air injection pipe (3) can perform a buffer function.

On the other hand, if the air inlet pipe 3 is sealed by the heater 173, while the operation of the suction module is stopped, the first actuator 150, the second actuator 160 and the third actuator 170 are restored to their original state. Accordingly, the nozzle 120 moves rearward and is drawn out of the air inlet pipe 3, and the first lever 161 and the second lever 172 are pivoted so that the clamp 163 and the heater 173 are upward. Move.

On the other hand, the start button 195 has been described as being installed in the control unit 190, but shown in Figure 8, it can be configured to replace the start button with a foot switch (foot switch) for convenient signal input.

In addition, the air injection device 100 described above is configured to operate by pressing and releasing the pressurization of the start button 195 once, but the process of closing the air injection pipe line 3 with the heater 173 after the pressure check The third actuator 170 may be configured to be operated by the signal input of the start button 195 so that the operator can check it as important.

In addition, although the air injection device 100 described above is described as having the second support 175 positioned in correspondence with the heater 173, the air injection pipe path 3 is formed up and down by configuring the second support 175 as a heater. Pressurized thermal fusion can be carried out at.

In addition, although the suction module 200 described above is configured to open the air inlet pipe 3 by the suction force generated while the compressed air passes through the venturi tube, it may be replaced by another vacuum pump or other various devices.
