BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling device, and more particularly to a filling device for filling a wide-mouthed container such as a can.

[0002]

2. Description of the Related Art FIG. 5 is a view showing a filling process by a conventional wide-mouth container filling device, in which a container 100 is conveyed horizontally (to the left in the drawing) by a conveying means. The nozzle 102 of the filling valve is lowered and inserted into the inside of the can, and while moving at that height, the liquid is filled into the can through the outer surface side of the nozzle 102. When the required amount of liquid has been filled (leftmost figure), the nozzle 102 is raised at a constant speed, and the nozzle rises above the can (rightmost figure) to complete filling. The filling valve is moved up and down by a cam or the like. For example, a linearly rising cam 104 as shown in FIG. 6 is used.

[0003]

However, in the above-described conventional wide-mouth container filling device, the can 100 and the nozzle 102 are provided.
Since and are moving at high speed, there is a problem that centrifugal force acts and the liquid 106 adhering to the outer surface of the tip of the nozzle 102 spills out of the can (see the second diagram from the right). It was

The present invention has been made in order to eliminate the above-mentioned drawbacks, and provides a filling apparatus for a wide-mouthed container which does not spill liquid even at high speed operation.

[0005]

SUMMARY OF THE INVENTION A filling device for a wide-mouthed container according to the present invention comprises a conveying means for horizontally conveying a wide-mouthed container, and a filling valve for moving together with each container to be conveyed. , Elevating means for elevating and lowering the filling valve, inserting the tip of the nozzle of the filling valve into the moving container to perform filling, and then raising the filling valve to bring the nozzle out of the container to complete the filling. And especially,
When the tip of the nozzle reaches a position higher than the liquid level and lower than the container port in the process of raising the filling valve, the raising of the filling valve is temporarily stopped and moved horizontally.

The second invention comprises a container base for carrying and carrying a wide-mouthed container, a filling valve located above each container to be carried and moving together, and an elevating means for elevating and lowering the container base. Provided, the moving container base is raised to insert the nozzle tip of the filling valve into the container for filling, and then the container base is lowered to bring the nozzle out of the container to complete the filling, Particularly, in the descending process of the container table, when the tip of the nozzle reaches a position higher than the liquid level and lower than the container port, the descending of the container table is temporarily stopped and moved horizontally.

[0007]

According to the above-mentioned invention, after the filling, the nozzle tip is stopped at a position higher than the liquid level and lower than the container mouth, and both are moved horizontally, so that they are attached to the outer surface of the nozzle. Since the liquid drops into the container, there is no risk that the surroundings will become dirty or that the content will not be sufficient.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments.
FIG. 3 is a plan view showing a filling device for a wide-mouthed container according to an embodiment of the present invention in a simplified manner. The wide-mouthed container conveyed by the conveyer 2 is introduced into the filling device 6 by an introduction means such as a star wheel 4. be introduced. The filling device 6 is provided with a container carrier such as a container stand, and each container is rotatably carried by this carrier while maintaining the same height. A filling valve is arranged above each container to be transported, and the container is rotated and moved at the same speed as the movement of the container. The filling valve is provided with an elevating means, which descends during rotational movement to insert the tip of the nozzle into the container and open the valve for filling. After the container is filled with a predetermined amount of liquid, the filling valve rises and the nozzle is taken out of the container to complete the filling, and then the container is discharged to the outside of the filling device 6 and passed through the conveyor 8 to the can seamer (sealing). 10 cans).

Next, the filling process will be described. Figure 1
[Fig. 2] is a diagram for explaining the operation of the filling device for a wide-mouthed container, and Fig. 2 is a diagram showing a cam for moving the filling valve up and down. In the figure, 12 is a can which is conveyed in a horizontal direction by a conveying means (not shown), 14 is a nozzle of a filling valve which is arranged above each can 12 on the conveying means, and is rotated and moved together with the can 12. Is filled into the can 12 through the outer surface of the nozzle 14. The cam 16 for moving the nozzle 14 up and down is, as shown in FIG.
The cam follower mounted on the filling valve 18 is designed to rise at a certain angle between the positions B and C, maintain a constant height between the positions B and C, and rise again between the positions C and D. Moves along the cam 16 and moves the filling valve nozzle 14 up and down.

In the filling device 6, after the can 12 is introduced, the nozzle 14 of the filling valve descends to the lowest position and is inserted into the can 12 to start filling. Filling is performed while the can 12 and the nozzle 14 rotate, and when a predetermined amount is reached (see the leftmost diagram in FIG. 1), the filling valve is closed and the nozzle 14 of the filling valve rises from point A (see FIGS. 2 and 3). Start. When the can 12 and the nozzle 14 reach the point B, the ascending of the cam follower 18 is temporarily stopped, and the nozzle 1
4 progresses while maintaining a constant height. At this time, the height of the nozzle is higher than the height of the liquid surface 20 in the can and is lower than the height of the can mouth 22 (see the two figures in the center of FIG. 1). The nozzle 14 starts rising again from the point C,
At the highest point D, the nozzle 14 is completely above the can 12 and the filling is completed (see the rightmost diagram in FIG. 1). afterwards,
This container is discharged to the outside of the filling device and sent to the can seamer 10. In the apparatus of this embodiment, when the nozzle 14 is raised after filling, the rise is temporarily stopped inside the can 12, so there is no risk of the liquid adhering to the tip of the nozzle scattering outside the can. In FIG. 1, the liquid level 20 in the can 12 is higher on the rear side in the traveling direction of the can due to centrifugal force.

In the above-mentioned embodiment, the filling device of the type in which the filling valve is moved up and down has been described, but it is needless to say that it can be applied to the type of filling device in which the container is placed on the container base and moved up and down. In this case, the same effect as that of the above-described embodiment can be obtained by first lowering the cam for raising and lowering the container base, then temporarily moving it in a horizontal state, and then lowering it again.

[0012]

As described above, according to the present invention, after the container is filled, when the nozzle is raised, the nozzle is temporarily stopped at a position above the liquid level and below the can mouth. , The liquid that has adhered to the nozzle does not splash outside the can due to centrifugal force. Further, when the container is lowered after filling, the same effect can be obtained by temporarily stopping when the nozzle reaches the same position.
