The determination step S7 is a step in which the results obtained in the detection steps S1, S3, and S6 are compared with each other at the same position on the arrangement of the containers 20 to determine the occurrence of an abnormality.
In the determination step S7, the determination unit 5 receives the detection results transmitted from the detection units 1A, 1B, and 1C, and stores them in combination with the array (P1, P2...) Information of the containers 20. And when the determination means 5 compares the detection result of the same position on the arrangement | sequence of the container 20, and a result changes like "Yes"->"No" (when a result is different), abnormality is said to have occurred. judge.

As shown in FIG. 2, when the detection results of the respective detection means in the arrays P1 and P4 are compared, “none” (the detection result of the upstream detection means 1A) → “no” (the detection result of the intermediate detection means 1B) → “ Since it is “No” (the detection result of the downstream detection unit 1C), the determination unit 5 determines that no abnormality has occurred. Specifically, in the series of processing, the determination unit 5 determines that there is no container 20 in the arrays P1 and P4 and no abnormality such as a broken bottle has occurred.
Further, when the detection results of the respective detection means in the arrays P2, P3, P5, P7, and P9 are compared, “Yes” (the detection result of the upstream detection means 1A) → “Yes” (the detection result of the intermediate detection means 1B) → Since it is “present” (the detection result of the downstream detection unit 1C), the determination unit 5 determines that no abnormality has occurred. Specifically, the determination unit 5 determines that the container 20 is always present in the array P2 and the like in a series of processes, and there is no abnormality such as a broken bottle.

On the other hand, when the detection results of the respective detection means in the array P6 are compared, “Yes” (detection result of the upstream detection means 1A) → “No” (detection result of the intermediate detection means 1B) → “No” (downstream detection means 1C) Therefore, the determination unit 5 determines that an abnormality has occurred. Specifically, the determination unit 5 determines that an abnormality such as a broken bottle has occurred in the section between the upstream detection unit 1A and the intermediate detection unit 1B, that is, in the processing of the gas filling unit 2.
Further, when the detection results of the respective detection means in the array P8 are compared, “Yes” (detection result of the upstream detection means 1A) → “Yes” (detection result of the intermediate detection means 1B) → “No” (downstream detection means 1C) Therefore, the determination unit 5 determines that an abnormality has occurred. Specifically, the determination means 5 determines that an abnormality such as a broken bottle has occurred in the section between the intermediate detection means 1B and the downstream detection means 1C, that is, in the processing of the liquid filling means 3 or the sealing means 4.

[Effects of filling apparatus and filling method according to this embodiment]
Next, effects of the filling device and the filling method according to the present embodiment will be described with reference to FIGS.

Since the filling device 10 according to the present embodiment includes the upstream detection unit 1A and the downstream detection unit 1C, and includes the determination unit 5 that compares and determines the detection results, the upstream detection unit 1A and the downstream detection unit 1C It is possible to determine the occurrence of an abnormality in the processing of the section.
In addition, since the filling device 10 according to the present embodiment further includes the intermediate detection unit 1B, it is determined whether the place where the abnormality has occurred is a section between the upstream detection unit 1A and the intermediate detection unit 1B. And the downstream detection means 1C can be specified.
As a result, for example, when it is specified that the location where the abnormality has occurred is the section between the upstream detection means 1A and the intermediate detection means 1B, it is only necessary to perform operations such as confirmation, cleaning, and processing of the location of the gas filling means 2, Operations such as confirmation of the location of the liquid filling means 3 and the sealing means 4 can be omitted.
Further, in the processing of the gas filling means 2 (section between the upstream detection means 1A and the intermediate detection means 1B) and the processing of the sealing means 4 (section between the intermediate detection means 1B and the downstream detection means 1C), comparison is made with respect to the container 20. However, the filling apparatus 10 according to the present embodiment can appropriately determine the occurrence of abnormality in these processes.

Since the determination means 5 of the filling device 10 according to the present embodiment determines the occurrence of abnormality by comparing the detection results at the same position on the array of the containers 20, the container 20 has a predetermined value on the array. It is possible to avoid erroneously determining that an abnormality has occurred in the case where the position is not originally arranged at the position.
Specifically, when the container 20 immediately after the start of the filling operation is not arranged (P1 in FIG. 2), or when the container 20 is not arranged in the middle of the arrangement for some reason (P4 in FIG. 2), the upstream detection is performed. The detection result “No” from the means 1A, the detection result “No” from the intermediate detection means 1B, and the detection result “No” from the downstream detection means 1C are transmitted to the determination means 5, and the determination means 5 is normal. It is determined that there is no occurrence. Therefore, the filling apparatus 10 according to the present embodiment can appropriately determine whether or not an abnormality has occurred even when the container 20 is intermittently transferred.

The filling method according to the present embodiment includes an upstream detection step S1 and a downstream detection step S6, and also includes a determination step S7 that compares and determines the detection results, so that the upstream detection step S1 and the downstream detection step S6 It is possible to determine the occurrence of an abnormality in the process during.
Moreover, since the filling method according to the present embodiment further includes an intermediate detection step S3, whether the step in which an abnormality has occurred is between the upstream detection step S1 and the intermediate detection step S3, It can also be specified whether it is between downstream detection process S6.
As a result, for example, when it is specified that the process in which the abnormality has occurred is between the upstream detection process S1 and the intermediate detection process S3, it is sufficient to perform operations such as confirmation, cleaning, and processing of the location of the gas filling means 2, Operations such as confirmation of the location of the liquid filling means 3 and the sealing means 4 can be omitted.
Further, in the process of the gas filling process S2 (between the upstream detection process S1 and the intermediate detection process S3) and the process of the sealing process S5 (between the intermediate detection process S3 and the downstream detection process S6), a comparison is made with respect to the container 20. However, according to the filling method according to the present embodiment, the occurrence of abnormality in these processes can be appropriately determined.

  Since the determination step of the filling method according to the present embodiment determines the occurrence of abnormality by comparing the detection results at the same position on the array of the containers 20, the container 20 is similar to the above-described filling device. Even in the case of intermittent transfer, it is possible to appropriately determine whether or not an abnormality has occurred.
