The forceps actuator 721 is connected between the lifting actuator 720 and the mask forceps 722 so that the mask forceps hold and release the mask 30 .

The mask clamp 722 is connected to the clamp actuator 721, the middle part of the clamp is bent twice in different axial directions, and it wraps the upper left transfer belt 731 and the left high transfer belt 741 without interference with the transfer belt. Hold only the central part of the mask in the transport direction.

The input air nozzle 723 is attached to the rear inclined surface connected to the mask gripping surface of the mask clamp 722 and sprays air so that the mask 30 and the mask earring are stably mounted in the pouch 20 .

The automatic mask packaging apparatus configured as described above operates as follows.

When the pouch supply unit 500 rotates and brings the pouches one by one directly under the pouch loading box 530, the base bars 110 that move tongs complete the separation from each other, and the shift bar 210 shifts to the left by the pouch work interval. After moving, close to each other to grip the pouch 20.

At this time, the intake operation of the air sucker of the pouch supply unit 500 is stopped so that the shift bar 210 can move the pouch 20 .

Then, when the shift bar 210 moves to the right to move the plurality of pouches to the next process, the fixing bars 310 that move with forceps come close to each other to grip the pouch 20 and fix it. At this time, in the opening portion 600, the air sucker 620 serves as a fixing bar.

In the same process as above, the pouch is moved to each process position.

When the pouch 20 comes to the opening portion 600 position, the air suckers 620 are spaced apart from each other on the left and right sides of the pouch entrance to open the pouch, and when the pouch comes to the mask input portion 700 position, the mask tongs 722 are used for the mask. (30) is put into the pouch (20).

At this time, when the mask is detected by the mask detection sensor 410 at the end of the mask transfer conveyor 400 in a state where the mask is waiting in the mask input unit, the mask transfer conveyor 400 is stopped and standby.

Then, when the pouch 20 with the mask is placed at the camera 800 position, the inside of the pouch is photographed and image processed from the upper side of the pouch.

After the image processing operation, in the process of moving the pouch 20 with a built-in mask to the sealing position, use the wide opening/closing air chuck for the pouch tensioner 240 mounted on the shift bar 210 to move the entrance tail of the pouch from side to side. Close the pouch opening by pulling to prevent wrinkles from forming during sealing.

Then, when the pouch comes to the sealing position, sealing operation is performed with the sealing bar 340, and at the discharge part 900 position, when the gripping force of the shift bar is released, the cylinder 910 push operation from the upper side of the pouch to quickly discharge the pouch.

A detailed operation of the mask input unit 700 is as follows.

Both edges of the mask 30 are driven by the upper left transfer belt 751, the upper left transfer belt 752, the upper right transfer belt 761, and the right upper transfer belt 762 for the mask 30 transferred from the mask transfer conveyor 400. The transfer belt is rotated 90 degrees from horizontal to vertical while being sandwiched between the transfer belts, and when the exit standby photosensor 765 detects the mask, the transfer belt operation is stopped.

Then, the forceps actuator 721 is operated while the earring of the mask is directed downward by the air injection of the input air nozzle 723, so that the mask forceps 722 grips the central part of the mask, and the lowering operation of the lifting actuator 720 Put the mask 30 into the pouch 20.

At this time, during the lowering operation of the lifting actuator 720, the upper left transfer belt, the left high transfer belt, the right upper transfer belt, and the right high transfer belt are driven in synchronization with the lifting actuator speed to smoothly discharge the mask 30 at the outlet side of the mask input unit. do.

Then, while preventing the mask from coming out by the air injection of the input air nozzle 723, the gripping force of the clamp actuator 721 is released to mount the mask in the pouch, and the lifting actuator 720 is raised to raise the mask clamp 722. make it so

By repeating the above operations, the mask input and packaging operation can be continued.
