  Further, the cross section of the air flow passage of the air blowing means 20 is gradually reduced as it goes downwind from the air blowing means 20. As this form, as shown in FIG. 11 and FIG. 12, the air flow channel side walls 21 provided on the left and right may be parallel, and the packaging bag placement table 3b may be inclined downward according to the downstream side of air flow. The air supply flow path side wall 21 provided on the left and right may be narrowed gradually in accordance with the downstream side of air supply to make the packaging bag placement table 3b horizontal (not shown), or the air flow provided on the left and right The passage side wall 21 may be gradually narrowed according to the downstream side of the air flow, and the packaging bag placement table 3b may be obliquely installed downward according to the downstream side of the air (not shown).

  Next, the packaging bag placement table 3b will be described. The packaging bag placement table 3b is substantially flat and mounted on the lower box 4 as shown in FIG. As shown in FIG. 21A, the packaging bag placement table 3b has a columnar locking pin 31 erected on the upper surface thereof, and a flat surface 32 on which the packaging bag 5 is placed is formed. And as shown in FIG.21 (b), there exists a form by which the air blower which is the ventilation means 20 is hungly provided by the lower surface.

  Next, the upper cover 2b will be described. As shown in FIG. 27A, the upper lid portion 2b covers the upper side of the lip portion 41 from the vicinity of the cutout portion 46 of the packaging bag 5 in the mounted state in plan view. The bag portion 45 has a left and right end vicinity 52 so as to cover the upper side of the range corresponding to the left and right ends of the bag 45 from the vicinity of the cutout 46 and the bag between the left and right end 52 It has a substantially U-shaped form in which an opening 60 from which the portion 45 can be taken out is formed. The peripheral state of the opening 60 makes the pulling direction open in order to separate the bag portion 45 from the lip portion 41, thereby facilitating or facilitating the separating operation.

  And as shown in FIG. 7, the left-right end vicinity of the bag part 45 is covered by the upper cover part 2a. As a result, the stacked bag portion 45 can be kept in an orderly stacked state without being flipped by the air flow from the fan or the air conditioner, and something held by the person in operation can be the packaging bag 5 Even if accidentally touching the side of a group or the like, the bag 45 is not directly hit and thus does not break.

  And as shown in FIG. 27 (b), the lower surface of the upper lid portion 2b is positioned downward at the position of the locking pin 31 of the columnar body inserted in the locking hole 42 of the lip portion 41 in plan view. There is a form in which the protruding projection 51 is provided vertically or a form in which the projection 51 is not provided (not shown). In either form, the upper end surface of the locking pin 31 of the columnar body inserted into the locking hole 42 of the lip portion 41 protrudes downward from the lower surface of the upper lid portion 2b or the upper lid portion 2b. The lower surface of the provided protrusion 51 is substantially abutted. The substantially contact means a close contact state or a state having a slight gap, and for example, a thin flexible portion, for example, a vinyl lip portion 41 can be pulled out of the locking pin 31 even when air is blown. It is sufficient if it can be prevented.

  Then, as shown in FIGS. 14, 15, and 29, a pressing means 10 for pressing the lip portion 41 from above is provided so as to hang downward from the upper lid portion 2b. This prevents separation of the lip portions 41 stacked in the vertical direction due to air flow. As another form of the pressing means, for example, there is a pressing means 11 as shown in FIG. 19, FIG. 20, and FIG. However, since the pressing means only needs to be capable of pressing the lip portion 41 of the packaging bag body 5 from above, it does not care about the form of FIG. 28 or FIG.

  Further, as shown in FIG. 28 or 29, the pressing means 10, 11 are provided with a baffle plate-like turbulent flow generating means 13 and a hole-like turbulent flow generating means 14 for generating turbulent flow in air flow. . Thereby, the locking hole 31 is inserted into the locking pin 31 to lock the packaging bag body 5 and the lip portion 41 is pressed by any one of the pressing means 10 and 11. Turbulent flow from the air blowing means 20 is generated toward the opening 47 of the bag portion 45 placed on the packaging bag placement table 3b. This turbulent flow has an effect of causing the surface portion 44 of the bag portion 45 having a thin thickness and flexibility, for example, to be instantaneously separated from the back surface portion 43 to open the bag portion 45. There is a problem that when the air flow is laminar flow, it may be difficult to separate the surface portion 44 of the bag portion 45 from the back surface portion 43. However, the surface of the bag portion 45 is changed by changing the air flow from laminar flow S to turbulent flow R. The portion 44 could be instantly separated from the back surface portion 43 to open the bag portion 45.

  The turbulent flow generation means may be provided in the air flow path so as to interrupt the laminar flow S, such as baffles or holes, which provide a discontinuous flow velocity or pressure, for example, as shown in FIGS. As shown in FIG. 28, a form of plate-like turbulent flow generation means 13 in which a part of the bottom wall of the substantially U-shaped pressing means 10 installed in the air flow path is cut and erected; As shown in FIG. 19, FIG. 20, and FIG. 28, the form of the turbulent flow generation means 14 of the hole provided in the pressing means 11 installed in the air flow channel, and further not the pressing means as shown in FIG. There is a form of the turbulent flow generation means 15 of the square bar provided at the tip of the packaging bag placement table 3b which forms the flow path of the air flow. However, since the turbulent flow generation means may be any means capable of generating a flow velocity or pressure discontinuity in the air flow to generate laminar flow, the above exemplified embodiment is not concerned.

  The generation of the turbulent flow R will be described. As shown in FIGS. 18 and 20, the air flow generated by the air blowing means 20 passes through the flow separation surrounded by the air flow path side wall 21 and becomes a laminar flow S while being changed in direction by the air flow path conversion wall 22 It will flow. When the laminar flow generation means 13 or the turbulent flow generation means 14 hits or passes the turbulent flow generation means 14 in FIG. 18 or the turbulent flow generation means 14 in FIG. The Karman vortices are generated and changed to turbulence R due to the generation of pressure discontinuities due to the generation of pressure discontinuities and the generation of pressure discontinuities. The turbulent flow R readily and easily realizes the separation between the surface portion 43 and the back surface portion 44 of the bag portion 45 having a thin thickness and flexibility, for example.

  When using the bagging apparatus 1b according to the present invention in the case of the second embodiment, as shown in FIG. 11, the power switch of the blower 20 is turned on immediately before holding the container 6 such as a pan by hand. The surface portion 44 of the uppermost packaging bag body 5 of the packaging bag bodies 5 stacked as shown in FIG. 14 is instantaneously separated from the back surface portion 43 by the turbulent air flow, and as shown in FIG. The opening 47 in the close contact state is opened widely. Then, as shown in FIG. 16, the storage item 6 such as bread is inserted into the opened bag portion 45 and pulled as it is from the lip portion 41 as it is cut off by the cutting portion 46 to store the storage matter 6 such as bread. It is possible to remove only the bag portion 45 in the state as described above. Then, the opening 47 of the bag portion 45 is closed to make a bag-packed product.
