  The air supply means 70 having such a configuration is such that the dry air supplied to the casing 30 having an internal space that is blocked from the outside except the upper surface cylindrical opening 32 and the pipe to be connected is between the upper surface cylindrical opening 32 and the turntable 22. It is discharged to the outside only from the gap.

[Action]
The operation of the rotary positioning device having the above configuration will be described below.
FIG. 5 is a flowchart of rotational positioning. FIG. 6 is an explanatory diagram of the operation of the lifting means. FIG. 7 is an explanatory view of the operation of the rotation positioning means. The rotation positioning of the container 11 is performed as follows. First, the container 11 is carried in (step 1). The container 11 held by the holder 62 of the transport means 60 is intermittently transported onto the rotary table 22 and temporarily stopped. At this time, as shown in FIG. 6 (1), a predetermined gap is generated between the bottom surface of the container 11 and the mounting surface of the rotary table 22.

  Raise the container (step 2). As shown in FIG. 6B, the entire casing 30 is moved upward by a predetermined distance by the lifting means 50. When the container 11 is placed on the mounting surface of the rotary table 22 and raised to a predetermined height, the container 11 is separated from the holder 62 and the contact is released.

  The container 11 is rotationally positioned (step 3). A control signal for rotating the rotary table 22 is sent from the control unit 28 to the drive unit 24, and the container rotates. At this time, even if the filling of the container 11 spills on the turntable 22 and falls onto the casing 30, the container is transferred to the drive unit 24 in the casing 30 due to the overlapping of the upper cylindrical opening 32 and the side surfaces of the lid-like turntable 22. Thus, the waterproofness of the entire apparatus can be improved without intrusion of the 11 filler.

  In addition, when moisture or moisture is generated in the manufacturing factory, it is preferable to supply dry air to the inside of the casing 30 by the air supply means 70. The dry air in the casing 30 continues to be discharged to the outside through the gap between the upper cylindrical opening 32 and the rotary table 22, so that the internal space of the casing 30 is kept in a dry state. It can be effectively prevented.

  Then, the marker printed on the side surface of the container 11 is detected by the detection unit 26. As illustrated in FIG. 7A, when a marker is detected, a detection value is transmitted to the control unit 28, and the control unit 28 transmits a control signal for rotating a predetermined angle from the detection position to the drive unit 24. This completes the positioning for aligning the printed display of the lid and the side surface of the container 11.

  The container 11 is lowered (step 4). The entire casing 30 is moved downward by a predetermined distance by the lifting means 50. The upper side of the container 11 is held by the opening periphery of the holder 62, and the contact between the mounting surface of the rotary table 22 and the bottom surface of the container 11 is released.

The container 11 is carried out (step 5). The container 11 held by the holder 62 of the conveying means 60 is moved from the rotary table 22 toward the subsequent sealing processing means.
In addition, even if cleaning water scatters during the cleaning of the apparatus, the filling material in the container 11 enters the drive unit 24 in the casing 30 due to the overlapping of the upper cylindrical opening 32 and the side surfaces of the lid-like rotary table 22. The waterproofness of the entire device can be improved.
Further, when the apparatus is steam sterilized, an increase in humidity or condensation may occur. In such a case, the air supply means 70 supplies dry air to the inside of the casing 30 to keep the internal space of the casing 30 in a dry state, thereby effectively preventing a malfunction of the drive unit due to moisture, moisture, and the like.

According to such a rotational positioning device of the present invention, moisture such as the filling material of the container and the cleaning water at the time of cleaning the device is supplied to the drive unit in the casing due to the overlapping of the upper cylindrical opening and the side surfaces of the lid-like rotary table. The waterproof property of the whole apparatus can be improved without invading.
Moreover, the drive part of a rotation positioning means can be easily attached or detached from the upper surface cylindrical opening of a casing. For this reason, by exchanging or repairing only the defective drive unit, it is possible to improve maintainability and increase the operating efficiency of the entire apparatus.

  The present invention has industrial applicability particularly in the field of manufacturing foods, medicines and the like.
