When the signal of the detection result and the signal of the detection result of the sensor 44 are received, an output release signal is sent to the solenoid 57. Here, in the packing member feeding means 2, the output motor 9 continues to output, but the packing member 8 is not fed because the pinching engagement of the packing member 8 of the roller set 11 is released. The opening opening means 3 also does not work.

Subsequently, the central processing unit 47 includes a driver 50
To output the output motor 36 to operate the positioning means 6. Here, the positioning means 6 secures a margin for closing and cutting when the second cam means is driven by the driving output from the output motor 36 to close the rear side in the traveling direction of the packing member 8. As described above, the lift member 42 lifts the corresponding portion of the packing member 8 that stores the article 23 to be packaged.

Further, the output motor 36 continues the rotation output,
The opening / closing means 29 is operated in cooperation with the cam means and the spring member to drive the opening / closing plate members 34 and 35 to the closed state. Here, the closing means 5 is operated to close the opening 24 corresponding to the packing member 8 accommodating the article 23 to be packaged. That is, the heater 38 and the pad body 39 cooperate with each other to
Is welded to close the vicinity of the opening 24 corresponding to the packing member 8 accommodating therein. At the same time, the closing means 4
Operates to close the rear opening 26 corresponding to the packing member 8 accommodating the article 23 to be packaged. That is, the heater 27 and the pad body 28 cooperate to pinch, weld, close, and thermally cut the rear portion to be closed corresponding to the packing member 8 containing the packaged object 23. .

Subsequently, the second cam means is driven by the rotational driving force from the output motor 36 during output, and the opening / closing means 29 operates to shift the opening / closing plate members 34 and 35 to the open state. By the shift of the opening / closing means 29 to the open state, the opening / closing plate members 34 and 35 are separated and moved to the open state,
Heater 27 and pad body 28 and heater 38 and pad body 3
9 are spaced apart. Accordingly, in the packing member 8, the engagement between the heater 27 and the pad body 28 and the engagement between the heater 38 and the pad body 39 are released, and the supply of heat is released.

As the opening / closing means 29 moves in the opening direction, the cam means is driven by the rotational driving force from the output motor 36 during output, and the positioning means 6 is also driven. That is, the lifting member 42 of the positioning means 6 releases the lifting state and becomes substantially in a hanging state. When the lift member 42 is in a substantially hanging state, the packing member 8 that has been lifted and held by the lift member 42 and stores the packaged object 23 and has the openings 24 and 26 closed.
Falls down.

The packaging device 1 repeats the above-described feeding of the packaging member 8 and the opening of the opening 24 to the dropping of the packaging member 8 that is packaging the article to be packaged 23, and the packaging proceeds by the number set by the operator.
