Hereinafter, the operation from filling the liquid to capping in the beverage filling line 1 having the above configuration will be described. Here, the operation when the container 2 which has been filled with the contents is mainly delivered from the intermediate wheel 4 to the capping device 6 will be described.
Here, the beverage filling line 1 of this embodiment is capable of so-called high-speed filling, for example, can process a container 2 of about 1000 bottles per minute, and the first and second intermediate wheels 4 and the capping device 6 are capable of processing. The rotating bodies R1 and R2 transport the container 2 while rotating at a high speed.
A container 2 filled with a content portion is supplied to the intermediate wheel 4, and the first gripper G1 of the intermediate wheel 4 is conveyed while gripping the neck portion 2b of the container 2.
At this time, a centrifugal force due to the rotation of the first rotating body R1 acts on the container 2, and since the first gripper G1 grips the neck portion 2b of the container 2, the container 2 is a container with the neck portion 2b as a fulcrum. The bottom portion of 2 is moved to the outer peripheral side and is in an inclined state.
When the container 2 is conveyed by the intermediate wheel 4 in this state, the container 2 is then delivered from the first gripper G1 to the second gripper G2 at the delivery position P with the capping device 6.
Centrifugal force toward the outer peripheral side of the first rotating body R1 acts on the container 2 until the delivery position P is reached, but when the container 2 is delivered to the second rotating body R2 at the delivery position P, the container 2 is then delivered. A centrifugal force directed toward the outer peripheral side of the second rotating body R2 acts on the second rotating body R2.
As a result, the inclination of the container 2 changes in the opposite direction at the delivery position P, and since the first and second rotating bodies R1 and R2 are rotating at high speed, the change in posture is abrupt. Become.

If there is such a sudden change in posture of the container 2, the liquid level of the contents bounces inside the container 2, and the bounced contents adhere to the outside of the neck portion 2b, or the container 2 It may pop out upward.
If the popped-out contents adhere to the inside of the cap 5 or the outside of the neck portion 2b of the container 2, if the cap 5 is attached to the container 2 as it is, the contents will be attached to the inside of the cap 5 and the container 2. It will remain between the outside of the neck portion 2b of the.
For example, when the content contains sugar, the sugar causes the cap 5 to stick to the neck 2b of the container 2, making it difficult to open the cap 5, or the content comes into contact with air, causing quality deterioration. There was a problem such as.

Therefore, in this embodiment, the cap cleaning means 13 and the neck cleaning means 14 are provided at the delivery position P of the capping device 6 to solve the problem caused by the liquid splashing from the container 2 described above.
First, when the container 2 is delivered at the delivery position P between the intermediate wheel 4 and the capping device 6, the capping head 11 holds the cap 5 above the second gripper G2 of the capping device 6. It is on standby and is located in an ascending position where the cap 5 is held upward as shown in FIG.
After that, the container 2 moves along the second rotating body R2 while being gripped by the second gripper G2, and the cap 5 held by the capping head 11 moves in synchronization with this.

By wetting the inside of the cap 5 with the cleaning liquid in this way, even if the contents of the container 2 adhere to the outside of the neck portion 2b, when the cap 5 is attached to the container 2, the contents are concerned. The concentration of the substance can be diluted by the cleaning liquid adhering to the inside of the cap 5. This makes it possible to prevent the above-mentioned problems as much as possible.
Further, the cleaning liquid sprayed on the cap 5 falls downward from the cap 5, but since this cleaning liquid falls on the partition plate 32 provided below the cap cleaning nozzle 31, it is prevented from entering the inside of the container 2. It has become like.
Further, since the partition plate 32 has a chevron cross section and the direction of the inclined surface intersects the movement locus of the container 2, the dropped cleaning liquid is collected by the partition plate 32 on the inner peripheral side of the movement locus of the container 2. And it is designed to fall to the outer peripheral side.

When the container 2 and the cap 5 pass through the cap cleaning means 13 in this way, the neck portion 2b of the container 2 is then cleaned by the neck cleaning means 14 with the cleaning liquid.
When the container 2 enters the neck cleaning section B, cleaning liquid is ejected from a plurality of neck cleaning nozzles 33 constituting the neck cleaning means 14, whereby the outside of the neck 2b of the container 2 gripped by the second gripper G2 is cleaned by the cleaning liquid. It will be washed.
At this time, since the neck cleaning nozzle 33 injects the cleaning liquid from diagonally above toward the neck 2b, it is possible to prevent the cleaning liquid from entering the container 2, and the plurality of neck cleaning nozzles 33 are provided at various angles. Therefore, it is possible to clean the entire outside of the neck portion 2b.

It is possible to prevent such problems as much as possible.
Further, when the cleaning liquid collides with the neck portion 2b of the container 2, the cleaning liquid is scattered at the neck portion 2b, but the cleaning liquid scattered upward is blocked by the partition plate 32, so that the cleaning liquid adheres to the cap located above. There is nothing to do.
As a result, when the content portion adhering to the neck portion 2b is removed by the cleaning liquid, even if the cleaning liquid contains the content, the component of the content is prevented from adhering to the cap 5, as described above. Problems are prevented.

Then, as shown in FIG. 4, the cap 5 held by the capping head 11 is waiting at the raised position in the neck cleaning section B, whereby the cap 5 interferes with the partition plate 32. It is designed not to be done.
Then, when the cap 5 passes through the neck cleaning section B, the elevating means 12 lowers the capping head 11, and when the cap 5 comes into contact with the neck 2b of the container 2 at the mounting position, the cap 5 is mounted on the neck 2b. It has become like.
Then, the container 2 to which the cap 5 is attached is then handed over from the capping device 6 to the discharge wheel 7, and further discharged to the subsequent process via the discharge conveyor 8.

In the above description, the reason and effect of wetting the inside of the cap 5 with the cap cleaning means 13 and cleaning the outside of the neck 2b of the container 2 with the neck cleaning means 14 have been described, but the shape of the container 2 is changed as another reason. There is.
That is, the neck portion 2b of the container 2 has a vertical slit formed in the screw portion in consideration of the discharge property of the adhered contents, but the one in which this is omitted is adopted for the reason of cost cutting or the like. It has become.
By omitting this vertical slit, it becomes difficult for the contents adhering to the screw portion to be discharged, and there is a problem that the contents are more likely to remain between the cap 5 and the neck portion 2b as compared with the conventional case. rice field.
According to the configuration of this embodiment, the contents remaining on the threaded portion on the outside of the neck portion can be sufficiently diluted with the cleaning liquid adhered to the inside of the cap 5 by the cap cleaning means 13. The neck cleaning means 14 makes it possible to remove the contents adhering to the outside of the neck 2b.

The capping device 6 of the above embodiment includes a cap cleaning means 13 for injecting a cleaning liquid onto the cap 5, and a neck cleaning means 14 for injecting a cleaning liquid onto the neck portion 2b of the container 2. It is also possible to omit one of them.
If only the cap cleaning means 13 is provided, the contents between the cap 5 and the neck 2b can be diluted by wetting the cap 5 with the cleaning liquid as described above, and the above-mentioned problems can be solved. can do.
Further, in such a configuration, the partition plate 32 may be provided only at the position where the cap cleaning nozzle 31 of the cap cleaning means 13 is provided.
