Description of the Related Art An automatic filling and packaging machine (apparatus) for automatically filling and packaging (heat-sealing) the above-mentioned powder granules and a film material to continuously produce multiple bags in a row is already known. There are various types, but the multiple bags delivered from this packaging machine are separated into single packages or double packages such as doubles and triples, and they are neatly placed in containers such as boxes and cases. The problem when accumulating is that the granules, which are the contents of the bag, are unevenly distributed in the direction of gravity control during the transportation process (automatic transportation) and form a non-uniform thickness when viewed as the entire bag. Therefore, it is indispensable to evenly and effectively utilize the upper and lower storage spaces. In order to solve this problem, a single packet or a continuous packet (hereinafter, single packet is taken as an example) is used to vertically stack the left and right parts in a vertical space, and the uneven distribution of granules. However, there is an example in which the upper and lower spaces in the container can be effectively utilized evenly between the left and right edges of the bag by superimposing them by mistake, as shown in FIG. 9, for example.

That is, the reference numeral 50 designates a machine body, and the neck portion 5 is provided on the upper portion.

A body portion 52 extending in a lateral direction downwardly connected to this, and a leg portion 53 which is connected to the body portion 52 downwardly in a substantially central portion are integrally formed. It is provided with a pair of left and right drop ports 511, 512 through which the filling and packaging bags A and B can be dropped in a state that they are held vertically.
The slanted passages 5a and 54b are connected to each other from the upper portion of the body portion 52 to the middle portion and are connected to the drop ports 511 and 512.
13 and 514 are formed. A deflecting arm 56 that reciprocally swings in a certain fan-shaped range by a rotating rotor 55 is provided substantially in the middle of the forked portions 54a and 54b of the separator and swings to either side of the passages 513 and 514 through which the falling bag passes. When this is done, the lower part of the side of the bag is hit to deflect it to an inclined state. At the lower left and right sides of the body 52, the rotor 33,
A plurality of rotating arms 31, ..., 41 ... radially provided in one rotation surface area are provided on the peripheral body of 43, and the arms 31, ..., 41 .. Rotate in the same direction at a constant speed and in a period (arrow). In addition, the holders 3 in the tangential direction are attached to the tips of the arms 31 and 41.
2, 42 are provided respectively. Reference numerals 34 and 44 denote rotor shafts connected to one power source (not shown). The container 6 is installed immediately below the machine frame leg portion 53 (see, for example, JP-A-56-106725).

[0004]

However, in the above-described automatic stacking device, the packaging bags A and B that drop through the left and right passages 513 and 514 have a long drop distance and a slow stacking speed, and also the holders 32 and 42. There is a problem that the packing bags A and B that can be received are unstable and it is difficult to collect them when they are arranged properly. In addition, the distance from the holders 32, 42 of the rotating arms 31, ..., 41 to the container 6 is considerably large, and the order in the container 6 is often disturbed. The present invention has been devised in view of the above-mentioned problems of the prior art, and the direction change fall distance in one direction of the packaging bags whose left and right directions are changed during stacking Most of them can be eliminated, and even one time can be used for turning time, even if it is less, the collection speed can be increased more than 1.5 times compared to the conventional one, and after receiving the packaging bag once in the peripheral storage part, An object of the present invention is to provide an automatic stacking device for packaging bags, which can stabilize the stacking posture by being put in the intermediate receiving wheel or the like. In addition, as another purpose, when the packaging bags are dropped from the intermediate receiving wheel onto the container or the conveyor, the packaging bags are sequentially stacked by the openable shutters from the left and right in multiple stages to eliminate the bounds due to the fall and stack the organized packaging bags. Get it.
