Become. The raw fabric 51 has a cylindrical shape, is pre-dipped and wound around a reel (not shown), and is intermittently fed out by a feeding device 52 in predetermined amounts.

First, press deaeration will be explained. As shown by solid lines in FIGS. 1 and 3, the swinging side wall 14 is opened with the press plate 6 raised, and the packaged items 12 are inserted into the four side walls 3 through the input hopper 16 and the input port 13. Have them put it in. At this time, the take-out port 18 is closed by the shutter 19, and the passage port 17 is closed by the extruded body 2.
2. Next, with the swing side wall 14 closed, the press plate 6 is lowered to compress the packaged object 12 between it and the bottom plate 4. At this time, a suction force is applied to the four side walls 3 by the suction duct 11 through the suction port 10, and the object to be packaged 1
Deaeration for 2 is promoted. As shown in FIGS. 1 and 3, the shutter 19 is opened with the object to be packaged 12 sufficiently reduced in size, and the extrusion device 21 is operated. As a result, the pushing body 22 moving forward pushes the object 12 to be packaged and pushes it into the guide body 24 through the outlet 18 . The shape of the pushed object 12 to be packaged is maintained by the guide body 24. Then, the second compression degassing is performed in the same way, but during this operation, the guide body
A bag body 27 is fitted onto the outside of the bag 6. That is, as shown in solid lines in FIGS. 1 and 6, the leading end of the original fabric 51 is held between the original fabric supply device 48. In this state, the original fabric supply device 48 is advanced, and the delivery device 52 is operated to pull out the original fabric 51 until its front end is positioned between the suction devices 34 . Next, the seal and cut device 47 is operated to cut the original fabric 5.
The bag body 27 is manufactured at the same time as cutting the bag body 1 to a specified length.
Then, the suction device 34 is moved closer, and the suction device 34 suctions the upper and lower surfaces of the open end of the bag body 27 as shown by the imaginary line in FIG. 1 and the solid line in FIG. Next, the suction device 34 is moved away to widen the opening end as shown by the imaginary lines in FIGS. 5 and 6. At this time, the original fabric supply device 48 has already retreated. Next, movable frame 3
3, the opening end is fitted onto both introduction plates 32 as shown by imaginary lines in FIGS. 44 and 5. At this time, the introduction plate 32 is opened and the front end of the movable frame 33 is in contact with the rear end of the movable member 30. Therefore, as the movable frame 33 advances thereafter, the introduction plate 32 also moves together. Thereby, the guide tube 27 can be fitted onto the outside as shown in FIG. At this time, the next packaged item 12 is being reduced and molded by the parallel operation, and by being extruded, the previous packaged item 12 inside the guide tube 24 is pushed back and pushed out from the guide tube 24. It will be done. At this time, the bag 27 also moves together, and the open package 43 is taken out onto the lift device 40. Then, the opening package 43 is transferred to the cross-feeding device 41 by the downward movement of the lift device 40. At this time, the movable frame 33 is moved backward, and the guide/stopper 37
The movable member 30 is also moved backward together. When the movable member 30 is received by the stopper 36, these backward movements are completed. The suction type deaerator 45 acts on the open package 43 that has reached the end of the cross-feeding device 41 through the opening, and the mouth seal device 46 is activated when the suction deaeration is sufficiently performed. The mouth is closed. The sealed package 44 thus obtained is conveyed by a discharge conveyor 42.

Effects of the Invention According to the present invention having the above-mentioned configuration, the object to be packaged, which has been deaerated and reduced in size by the pressing type deaerator, is pushed into the guide body by the extrusion device, and on the other hand, the bag body is externally fitted onto the guide body by the bag body supply device. By doing so, the bag can be packed with the object to be packaged through the guide body. By backing up the packaged item in the guide body with the next packaged item, the previous packaged item can be pushed out of the guide body and positioned inside the bag, and the opened package can be placed on the lift device. can be taken out. After that, the opening package is separated from the guide body side by the operation of the lift device, and while being sent by the cross-feeding device, the inside of the bag is degassed again by the suction type degassing device, and then
By operating the mouth sealing device, the mouth of the bag can be sealed, and thus a sealed package can be easily and efficiently obtained through a series of flows. Furthermore, when applying a pair of sheets to an object to be packaged to form a sealed package, the equipment becomes complicated and the object cannot be reduced to a sufficiently small size. By means of a simple device, a well-reduced sealed package can be obtained from the insertion.
