Description

  The present invention relates to a rotary filling device that fills containers such as bottles and cans with liquids such as beverages.

  In a rotary filling device that fills containers such as bottles and cans with liquids such as beverages, in order to increase the filling capacity, a filling valve that is generally provided on a rotating body of the filling device and correspondingly corresponds to the filling valve. This is achieved by increasing the number of container holding means provided, that is, by increasing the diameter of the rotating body. Further, the empty containers supplied from upstream are divided into two rows and arranged in parallel. In many cases, two filling devices are used for filling. In addition, a technique for increasing the filling time of the container as much as possible while the rotating body is rotating, and when supplying empty containers to the container holding means, two empty container supply devices are used, and one filling device is used. A filling technique is disclosed. (Patent Documents 1 and 2)

  In addition, the filling element (filling valve) and the container support (container holding means) provided in the circumferential equal part in the rotary filling device are provided in two upper and lower stages to improve the filling capacity. (Patent Document 3)

JP 2000-335689 A (FIG. 1) Japanese Patent Laid-Open No. 7-41088 (FIG. 1) JP-T 2009-543739 (FIGS. 1 and 2)

According to Patent Document 1, in a rotary filling device in which a solenoid valve is used to open and close a filling valve provided on a circumferentially equal portion of a rotating body, and the timing of filling start is electrically controlled, A rotational position detecting means for detecting the absolute rotational position and a speed detecting means for detecting the rotational speed of the rotating body are provided. When the rotational speed of the rotating body is increased, the rotational position for outputting an opening command to the filling valve. Is changed to the upstream side in the rotation direction.
However, in the technique of the above-mentioned Patent Document 1, the filling position can be improved by extending the rotational position that becomes the filling section of the filling apparatus to the upstream side and ensuring a time effective for filling, There is a fear that the effect is limited.

Next, the cap is tightened on the container mouth by the cap tightening device 11 after being delivered from the star wheel device 10 to the cap tightening device (container capping device) 11, and then passed through the outlet star wheel device 12. Then, it is discharged in the direction of arrow h in the next process.

In addition, the positions of the upper filling valve 22a group and the lower filling valve 22b group of the filler 2 are shifted on the plane, and the height positions of the filling valve 22a and the filling valve 22b are as shown in FIG. The height of the filler 2 is lowered by being partially wrapped.
Further, the leakage prevention guard 29 prevents the leaked liquid from contaminating the lower filling valve 22a or the container when the liquid leaks from the upper filling valve 22b or the container corresponding thereto.

As described above, the upper and lower two-stage filling apparatus according to the present invention distributes and conveys the containers P conveyed in one row from the upstream to the upper and lower two stages by the container distributing apparatus 4, and thereafter, in the filler 2, the upper and lower two stages. After the liquid is filled with the filling valve 22a and the filling valve 22b, the container collecting device 9 collects the liquid from the second stage to the first stage.
Further, by providing the container interval reduction conversion device 5a and the container interval reduction conversion device 5b after the container distribution device 4 to reduce the conveyance interval of the containers P, the filler 2 can be made compact.
