Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning system for a rotary filling machine, and more particularly to a cleaning system for supplying a cleaning cup below a filling valve to clean each filling valve.

[0002]

2. Description of the Related Art Conventionally, the following is known as a cleaning system for a rotary type filling device. That is, a rotatable body, a plurality of elevating tables that are placed at equal intervals in the circumferential direction of the rotating body to mount and elevate a container, and a rotating body that is provided on the rotating body to store a filling liquid. And a plurality of filling valves communicating with the filling liquid tank and arranged above the respective lifting tables to fill the containers placed on the lifting tables with the filling liquid. A rotary filling device is provided, and a washing cup is supplied to the rotary filling device at a predetermined delivery position, or a delivery device is provided to discharge the washing cup from the rotary filling device. It is known that the filling valves are washed directly under the respective filling valves (for example, JP-A-6-1397). When cleaning the filling valve with such a conventional device, the cleaning cup is engaged with the filling valve as follows. That is, first, the cleaning cup is supplied to the lower side of the filling valve stopped at the delivery position by the arm of the delivery device.
Next, the washing cup is raised by the arm, and the washing cup is engaged with and connected to the lower end of the filling valve. Then, the rotary filling device and the delivery device are rotated in synchronization. As a result, the filling valve connected to the cleaning cup moves from the delivery position to the adjacent position, and the arm holding the cleaning cup also moves to the adjacent position. As a result, the next filling valve stops at the delivery position, and the cleaning cup held by the new arm is supplied to the position below the filling valve stopped at the delivery position. And
After that, the arm is lifted, so that the cleaning cup is connected to the filling valve stopped at the delivery position. In this way, all the filling valves provided in the rotary filling device are sequentially stopped at the delivery position, and the arm holding the washing cup is raised to engage the washing cup with each filling valve. Then, as described above, when all the filling valves are engaged with the washing cups, the washing liquid is circulated through the filling valves and the washing cups in that state to wash each filling valve. Further, when the cleaning operation of each filling valve is completed in this way, the filling valve and the cleaning cup engaged with it are sequentially stopped at the delivery position, and the filling valve is reversed in the reverse order of the engagement described above. The cleaning cup was separated from the container and discharged.

[0003]

As described above, conventionally, when the cleaning cup is attached to and detached from each filling valve, the arm is moved up and down for each filling valve at the delivery position. However, there is a drawback that it takes a long time to complete the cleaning work.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, according to the present invention, a rotatably provided rotating body and a container placed at equal intervals in the circumferential direction of the rotating body to mount and elevate a container. A plurality of lifting tables, a filling liquid tank provided in the rotating body for storing a filling liquid, and communicating with the filling liquid tank,
In addition, the rotary filling device is provided at a position above each lifting table and configured with a plurality of filling valves for filling the filling liquid into the container placed on the lifting table, and at the predetermined delivery position, It is equipped with a delivery device that supplies the cleaning cup to the rotary filling device, or discharges the cleaning cup from the rotary filling device, and fills them while the cleaning cup is positioned directly below each filling valve of the rotary filling device. In a cleaning system of a rotary filling device for cleaning valves, a supporting member is provided on the rotating body so as to be able to move up and down, and a holding unit for holding a cleaning cup corresponding to the number of the filling valves on the supporting member. And an elevating mechanism for elevating and lowering the support member,
The delivery device is configured to supply the cleaning cup to each holding portion at the delivery position or to discharge the cleaning cup from each holding portion located at the delivery position.

[0005]

According to this structure, when the filling valve is washed, the rotary member is rotated by the required amount to sequentially stop each holding portion at the delivery position and at the delivery position by the delivery device. A washing cup is sequentially supplied to each of the holding parts. Next, when the washing cups are held by all the holding portions, the supporting member is raised, whereby the washing cups are simultaneously engaged with the filling valves from the lower side. Then, in this state, a cleaning liquid is circulated through each filling valve for cleaning. When the cleaning operation of each filling valve is completed in this way, all the cleaning cups can be simultaneously separated from each filling valve by lowering the support member. Then, after that, the rotating body is rotated by a required amount to stop each holding portion at the delivery position, and the cleaning cup is sequentially discharged from the holding portion stopped at the delivery position by the delivery device. As described above, in the present invention, when the cleaning cup is attached to and detached from the filling valve, it is possible to simultaneously attach and detach all the filling valves. Therefore, the time required for the cleaning work can be shortened and the speed of the cleaning work can be increased as compared with the conventional case where the cleaning cup is moved up and down for each filling valve stopped at the delivery position to perform the mounting and demounting work.
