The code assigning device 70 is configured, for example, to assign a code corresponding to each unit of the second unit group 52 to the pouch. Specifically, for example, for each of the eight units forming the second unit group 52, A, B, C ...
Codes such as G and H are printed. The code may be a number or a symbol. Further, the printing method may be printing or engraving, and its form does not matter.

Next, the operation of the apparatus of this embodiment will be described. First, from the two pouch supply devices 30, the pouches 1 are alternately arranged one by one to each pouch holder 2 of the rotary device 20.
4 are sequentially supplied. At this time, the adsorbent 26 shown in FIG.
Is in the release position, and the pouch 1 is held on one side only by the adsorbent 25 (25A and 25B). As the rotary device 20 rotates, the pouch holder 24
While advancing from the position of the pouch supply device 30 to the position of the spout supply device 40, the other adsorbent 26 returns to the adsorbing position of FIG. 4 and adsorbs the pouch by its adsorbing force to the open position again. The pouch 1 is largely opened by the movement of. With the pouch open, the pouch 1 is brought to the position of the spout supply device 40 and the spout 2 is inserted into the opening of the pouch. Then, the adsorbent 26 returns to the original position again. After that, the sandwiching members 27A2 and 27B2 hold the spout 2 through the pouch 1 with the opposing sandwiching members 27A1 and 27B1 paired with them and the respective V-shaped groove portions. When the pouch 1 held by the pouch holder 24 and the sandwiching members 27A and 27B reaches the reciprocating swivel device 50 that is moving forward at the same speed as the rotary device 20, when the pouch 1 is held by the first unit group 51. The primary edge (for example, heat seal) is applied to the flat edge of the opening, the secondary unit group 52 performs the secondary seal (for example, heat seal), and the third unit group cools the seal portion. That is, each of the pouches 1 held by the eight pouch holders 24 is primary sealed at once by the first unit group 51, and the eight pouch holders are held while the reciprocating and swiveling device 50 moves back and forth again. The body 24 reaches the position of the second unit group 52, where the pouch is secondarily sealed,
While the reciprocating and slewing device 50 returns to the original position and then moves forward, the position of the third unit group 53 is reached and the pouch is cooled. Thus, the pouch is sealed at its opening, which seal holds the spout by the pouch. Thereafter, the spout-equipped pouches whose seals are cooled are taken out one by one by the take-out device 60 and taken out. This pouch with spout is once stored in a stacker or is conveyed to a filling device in a line where the contents are filled. In the above, for the pouch with spout, for example, by visual inspection, defective products are extracted before filling the contents, and only good products are used for filling the contents. The pouch has a unique code corresponding to each unit in the second unit group for sealing, and it is possible to determine which unit has an abnormality simply by looking at the code of the defective product. Further, the contents of the abnormality can be estimated by looking at the form of the defective product. Further, when it is determined that each unit of the second unit group is normal and has no defect despite the occurrence of defective products, it is considered that the holding unit has an error. Although a large number of holding units are provided, the number of holding units and the number of processing units are integer multiples, and there is a fixed relationship between the two, so it corresponds to the processing unit that was initially suspected to be defective. The number of holding units used is limited. That is, there are only the above integer multiples. The response is also clear. Therefore, these processing units are immediately identified and inspected for them.

[0028]

As described above, according to the present invention, the number of holding units and processing units is in an integral multiple relationship, each holding unit is given an identification number, and each processing unit assigns a specific code to a corresponding packaging body. Since it is attached, it is possible to immediately identify the abnormal processing unit and the holding unit to deal with it, and repairs etc. can be handled very quickly, simplifying the work and suppressing the amount of defective products. It will be possible.
