Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a filling device for filling a container such as a bottle with liquid, and more particularly to an improvement in a lifting table for lifting and lowering the container.

``Prior Art'' Conventionally, a filling device for filling a container with a filling liquid has a plurality of filling mechanisms arranged at a certain pitch and transported together with the container to fill each container with the filling liquid. A device is known that includes a plurality of lifting tables, each of which is disposed below a filling mechanism and lifts a placed container toward each filling mechanism.

By the way, the maximum size of containers that can be placed on a lift table arranged at the same pitch is one whose outer diameter in the transport direction is slightly smaller than the pitch. For this reason, in a dual-purpose filling device, by supplying every other container to each lifting table, it is possible to fill a large container with filling liquid even if the outside diameter is larger than the above-mentioned outside diameter. ing. In this case, the size of the container is limited to a size that does not allow the container to come into contact with an adjacent empty lifting table.

``Problem to be solved by the invention'' However, when filling larger containers with liquid, each lifting table should be made smaller so that the large container does not come into contact with an adjacent empty lifting table. However, as mentioned above, in the past, the width of each lifting table in the transport direction was set to be the same, so if all lifting tables were made smaller, stability would deteriorate when large containers were fed onto the lifting table. .

"Means for Solving the Problems" In view of such circumstances, the present invention provides the above-mentioned conventional filling device in which the widths of the lifting tables in the conveying direction are alternately made different.

``Function'' With such a configuration, not only can small containers be stably placed on all lifting tables, but also large containers can be fed onto a large lifting table with a large width. This also allows for stable placement.

"Example" The present invention will be described below with reference to the illustrated example.
In FIG. 3, the filling device 1 is equipped with a filling liquid tank 2 in which filling liquid is stored, and this filling liquid tank 2 is fixed to a rotary table 4 by a plurality of supports 3. This rotary table 4 is rotationally driven by a drive motor (not shown) to rotate the filling liquid tank 2 in the counterclockwise direction in FIGS. 1a and 1b. The filling liquid can be supplied through the

As shown in FIGS. 2a and 2b, a plurality of filling mechanisms 6 are arranged concentrically at the same pitch p on the outer periphery of the lower surface of the filling liquid tank 2, and each filling mechanism 6 fills It has a filling nozzle 6a that can communicate with the inside of the liquid tank 2. Each filling nozzle 6a is normally closed, and is opened by the container 8 which is raised by the lifting tables 7a, 7b to fill the container 8 with a predetermined amount of filling liquid.

Further, the elevating tables 7a, 7b are provided on the outer periphery of the rotary table 4 so as to be able to rise and fall freely. Pituchi p
is also the same as the pitch p between each filling mechanism 6.

As shown in FIGS. 1a and 1b, the elevating tables 7a and 7b are a large elevating table 7a and a small elevating table 7b having different widths in the transport direction.
They are arranged alternately in the circumferential direction, and the intervals between the large lifting tables 7a and the small lifting tables 7b in the circumferential direction are set small. Further, a ring-shaped cam 9 for raising and lowering the lifting tables 7a, 7b is fixedly arranged below each lifting table 7a, 7b, and each lifting table 7a, 7b is engaged with the cam 9 (FIG. 3).

Furthermore, a supply side star foil 10a and a discharge side star foil 10b are respectively disposed outside the rotary table 4 in close proximity thereto, and empty containers 8 conveyed by the conveyor 11 are placed on a guide member 12. Lifting tables 7a, 7 along the sides of
b, and the filled containers 8 are conveyed from the top of the lifting tables 7a, 7b to the conveyor 11 by the star foil 10b on the discharge side.
It is made so that it can be carried upstairs.

In the above configuration, when the container 8 to be filled is a small container, as shown in FIG. 1b and FIG. Similar to the device, a small container can be filled with filling liquid.

On the other hand, as shown in Figures 1a and 2a,
When the container 8 to be filled is a large container, the large container can be supplied and filled with the filling liquid only onto the large lifting table 7a. At this time, the supply side star foil 10a and the discharge side star foil 1
Of course, 0b is replaced from one for small containers to one for large containers (No. 1a).
(see Figure 1b).

The operation of filling the large container 8 with liquid will be described below. In FIG. Every other one is sequentially supplied and placed only on the lifting table 7a. When the filling liquid tank 2 and the rotary table 4 are rotated together in the counterclockwise direction in FIG. 1 by the above-mentioned drive motor, the filling mechanism 6
The lifting tables 7a, 7b are also rotated counterclockwise, and each lifting table 7a, 7b is raised by the cam 9 mentioned above.

As shown in FIG. 2a, a large lifting table 7a
The small elevating table 7b located before and after the large elevating table 7a will rise before and after the large elevating table 7a. Since they do not come into contact with each other, and the large container 8 is placed on the large lifting table 7a, it will not be in an unstable state.

When the large container 8 is raised and a predetermined amount of filling liquid is filled into the large container 8 from the filling nozzle 6a, the filled large container 8 is lowered as the large lifting table 7a descends and is discharged. It is carried out onto the conveyor 11 from the lifting table 7a by the side star wheel 10b.

"Effects of the Invention" As described above, according to the present invention, a larger container can be stably placed on a lifting table than in the past.
