Further, a spout holder portion 142d, which is a means for holding the spout portion of the flexible bag, is lowered in a direction indicated by an arrow 61 on a side surface facing the opened side surface 142c-4, that is, a part of the upper end of the side surface 142c-2. An open portion 142c-2a is provided. Further, the bottom surface 142b is provided with an insertion port 142b-1a for raising the fixed base 142e for pressing the spout of the flexible bag from below in the direction indicated by the arrow 62. The retainer 142 can be used without modifying the conventional rotary filling machine for the can of the can by matching the outer shape and size of the can of the can. However, the present invention is not limited to this.

  FIG. 12 is a diagram showing a case where an empty flexible bag 141 is set on the retainer 142. A flexible bag connected in a strip shape (not shown) is separated into one flexible bag 141 and then supplied to the retainer 142 (FIG. 12 ( a)). In this case, if the cap is sealed on the spout 141b of the flexible bag 141, the cap is removed.

  On the other hand, in the retainer 142, the spout holder part 142d is lowered in the direction of the arrow 61 at the opening part 142c-2a, and the fixed base 142e is raised in the direction of the arrow 62 at the insertion port 142b-1a.

  Next, the empty flexible bag 141 is set on the retainer 142. When the empty flexible bag 141 is set on the retainer 142, the flexible bag 141 is set while being held by the spout holder portion 142d (FIG. 12B).

  When a funnel can filling machine is used as the filling machine, the position where the flexible bag 141 is set in the spout holder part 142d is the position of the content outlet of the funnel can, so that the funnel can filling machine There is no need to remodel.

  FIG. 13 is a view for explaining a state in which the flexible bag 141 is held and set by the spout holder portion 142d. FIG. 13A is a top view of the spout holder part 142d and the spout 141b. The spout 141b of the flexible bag is pushed in the direction of the arrow 80, and the spout connection part 141b-4 of the spout 141b is a recess of the spout holder part 142d. 142d-1 (FIG. 13B). In this case, the size (D1) of the concave portion of the spout holder portion 142d is slightly smaller than the diameter (D2) of the spout connection portion 141b-4 of the spout 141b, so that the spout holder portion 142d can be easily held.

  FIG. 14 shows an example of a method for holding the spout 141d of the flexible bag 141 on the spout holder 142d. A spout pusher 155 which is a flexible bag setting means is inserted between the hinges 141b-2 and 141b-3 of the spout 141b of the flexible bag 141 (FIG. 14A). FIG. 14B is a view as seen from the direction of the arrow 81 in FIG. Further, the spout pusher 155 is inserted between the hinges 141b-2 and 141b-3 of the spout 141b and moved in the horizontal direction to push the spout connection part 141b-4 of the spout 141b into the recess of the spout holder part 142d (FIG. 14). (C)). In this way, the empty flexible bag 141 is set on the retainer 142.

In this case, since the flexible bag 141 is suspended from above, the contents can easily spread in the bag-shaped bag body 141a, and a prescribed amount can be filled.

  After filling, the filling nozzle 144b is retracted, and then the fixed base 142e is further raised in the direction of the arrow 63 as shown in FIG. 16 to press down the spout 141b of the flexible bag from below. In this state, as shown in FIG. 17, the cap holder 153 is lowered in the direction indicated by the arrow 64, and the cap 154 is plugged into the spout 141b. In this case, the spout 141b is held by the spout holder portion 142d, and the spout 141b is pushed by the fixed base 142e, so that the cap is not plugged obliquely, and the cap can be securely fitted. Further, since the fixed base 142e presses the spout 141b of the flexible bag from below, it can serve as a so-called airless fill used when filling the flexible bag, so that the air remaining directly under the spout 141b can be eliminated.

  In the above description, the spout holder portion 142d and the fixed base 142e are examples, and the present invention is not limited thereto.

  In the flexible bag filled with the liquid contents and capped in this manner, the spout held by the spout holder portion 142d is released from the spout holder portion 142d (for example, the spout is reversed in the direction opposite to that during setting). 9), the spout holder 142d rises above the retainer, and after the fixed base 142e descends and retracts to the lower side of the retainer, it is transferred to the transfer device 149 by the carry-out conveyor 146 shown in FIG. Then, it is transferred to a cardboard 147.

  As the cardboard box making apparatus 148 for making the cardboard box 147 for storing the flexible bag filled with the liquid contents, a generally used cardboard box making apparatus can be adopted.

  The transfer device 149 is a device for transferring and storing the flexible bag filled with the liquid content from the carried retainer into the boxed cardboard, and after the retainer is conveyed onto the opened cardboard, the cardboard As shown in FIG. 18, the retainer bottom 142b rotates and opens in the direction of arrow 82, so that the flexible bag 141 filled with the liquid content falls in the direction indicated by arrow 83 and is stored in the cardboard. Is done. The method for storing the flexible bag 141 in the cardboard is not limited to the above-described dropping method.

  As the cardboard sealing device 150 for sealing the cardboard in which the flexible bag filled with the liquid content is stored, a generally used sealing device can be adopted.

  On the other hand, the empty retainer 142 is conveyed to the flexible bag setting device 143 by the collection conveyor 151, and then the empty flexible bag 141 is set again. Thus, the retainer 142 is used in a circulating manner. In addition, the retainer 142 can be folded so that the storage location can be suppressed.

  In the above description, the rotary type filling machine is exemplified, but a vertical type filling machine may be used. FIG. 19 is a schematic diagram showing a schematic configuration of a bag-in-box manufacturing apparatus using a vertical filling machine. A bag-in-box manufacturing apparatus using a vertical filling machine includes a retainer 142, a flexible bag setting means 143, a filling machine 55, a cardboard box making means 148, a flexible bag transfer means 149, and a cardboard sealing means 150. Empty retainer collecting means 151.

In the case of a bag-in-box manufacturing apparatus using a vertical filling machine, the flexible bag 141 is set on the retainer 142 by the flexible bag setting means 143. As the retainer 142, the same retainer as that of the rotary type filling machine can be used. The retainer 172 in which the flexible bag 141 is set is carried into the retainer stop 171 by the carry-in conveyor 145. The carried-in retainer 172 is once fastened to the retainer stop 171 and (in the case of FIG. 18), when three retainers are aligned, it is carried into the filling unit 175 by the carry-in conveyor 152. Thereafter, the liquid content is filled by the filling unit 174 of the filling unit 175.

  As each processing means after filling, the same processing means as in the case of the rotary filling machine can be used.

  As described above, according to the bag-in-box manufacturing apparatus and method of the present invention, the rotary filling machine can be set so that the flexible bag can be accurately held in the retainer, and further filled into the existing funnel can. In addition, since it can be filled using a vertical filling machine, a large amount of equipment costs and installation space are not required, high speed filling is possible, a specified amount can be filled, and a stable cap can be plugged. In addition, it is possible to prevent the liquid content from adhering to the outer box and the paper powder foreign matter from the outer box from being mixed into the liquid content. Furthermore, there is an advantage that the retainer can be used in a circulating manner.
