Therefore, a loss occurs in the primary cleaning region having a preset length, and it becomes impossible to carry out cleaning as set time. Further, when a plurality of types of fluids are sequentially ejected for cleaning, the order of the cleaning fluids to be ejected is determined in order to perform efficient cleaning. If the container is processed by injecting the secondary cleaning fluid before the cleaning fluid, there is a problem in that the cleaning process may be distorted.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and a plurality of kinds of cleaning fluids are sequentially supplied by spraying them to a container by switching and connecting a nozzle and respective supply sources. In a rotary rinser, before injecting the primary cleaning fluid, drain the fluid remaining inside the nozzle and piping, replace the interior with the primary cleaning fluid, or empty the interior. It is an object of the present invention to provide a rotary type cleaning device in which the fluid for primary cleaning can be immediately jetted when it reaches the primary cleaning region by keeping the above state.

According to a second aspect of the present invention, an air supply source for supplying air to the nozzle is provided, and a passage connecting the air supply source and the nozzle is provided between the container discharge means and the container supply means. It was formed.

[0010]

In the rotary cleaning apparatus according to the first aspect of the present invention, the passages between the plurality of fluid supply sources and the nozzles are switched and connected by the switching means, so that a plurality of kinds of fluids are stored in the container in the processing area. After spraying sequentially and after cleaning, in the idle region until the bottle gripper discharges this container and receives the next container, of the above-mentioned multiple types of fluid, the fluid that is first injected in the processing region is nozzled. Send to. Then, the fluid that was ejected at the end of the processing region and remained in the passage from the switching means to the nozzle is replaced with the first fluid. Therefore, when the fluid is ejected to the next container, the fluid to be ejected first is immediately ejected without delay.

Further, in the rotary type cleaning device according to the second aspect of the present invention, after the cleaning is completed and the container is discharged, air is blown into the nozzle in the idle region so that it is injected at the end of the processing region and the switching means. The fluid remaining in the passage from the switching means to the nozzle is emptied in the passage from the switching means to the nozzle. As a result, the last fluid is not jetted to the next container before the first fluid is jetted.

Although the secondary cleaning fluid remains, the residual secondary cleaning fluid is discharged from the nozzle 22 by the primary cleaning fluid being sent in the idle region F, and the remaining inside of the nozzle 22 and the nozzle pipe 24. Are replaced by the primary cleaning fluid.

By thus discharging the secondary cleaning fluid from the nozzle 22 and the nozzle pipe 24 and replacing it with the primary cleaning fluid, the container 20 is cleaned when the next container 20 is cleaned. Upon entering the primary cleaning area B, the primary cleaning fluid is immediately discharged. Therefore, it is possible to reliably secure the predetermined cleaning section. In addition, since the secondary cleaning fluid is not sprayed onto the container 20 before the primary cleaning, the cleaning process is not disturbed,
It is possible to accurately carry out a given cleaning process.

In the above embodiment, a supply source of the primary cleaning fluid is connected to the small hole 32f of the fixed plate 32 arranged in the idle running region F so that the nozzle 22 and the nozzle pipe 24 remain. Although the secondary cleaning fluid was replaced with the primary cleaning fluid, the small hole 32f of the fixed plate 32 may be connected to the air supply source. In this case, the air is fed in the idle running region F to discharge the secondary cleaning fluid remaining in the nozzle 22 and the nozzle pipe 24 to empty the inside,
It is possible to perform a predetermined cleaning process without injecting the secondary cleaning fluid onto the container 20 before the primary cleaning fluid is sprayed in the next primary cleaning region B.

The cleaning fluid supplied to the nozzle 22 in the above-mentioned primary cleaning and secondary cleaning may be different kinds of fluids, and various combinations are possible.

For example, a. Hypochlorous water is used as the primary cleaning fluid, pure water is used as the secondary cleaning fluid, and the primary cleaning fluid is supplied to the nozzle 22 in the idle running region F where the container 20 is supplied and discharged. Pipe 24
The pure water inside is replaced with hypochlorous water. In this way, by replacing the fluid used in the previous secondary cleaning with the primary cleaning fluid before performing the primary cleaning, hypochlorous water is added to the next container 20 in the primary cleaning at the same time when the cleaning is started. Since it can be sprayed, no loss occurs in the cleaning time, and effective and reliable cleaning can be performed. Further, unlike the case of the conventional device, since the pure water that is the secondary cleaning fluid is not sprayed before the cleaning with the hypochlorous water that is the primary cleaning fluid, the desired accurate cleaning is possible. The process can be executed.

B. Similar to the above a, hypochlorous water is used as the primary cleaning fluid, pure water is used as the secondary cleaning fluid, and in the idle running region F for supplying and discharging the container 20, it is connected to an air supply source. Make sure to blow out air. In this case, since the pure water remaining in the nozzle 22 and the nozzle pipe 24 after the secondary cleaning is blown out by the air, at the start of the primary cleaning of the next container 20, the inside of the nozzle 22 and the nozzle pipe 24 is It's empty. Therefore, the secondary cleaning fluid is not sprayed before the primary cleaning fluid is sprayed, and the accurate cleaning process can be executed. Further, when the nozzle pipe 24 is empty, a slight time lag occurs before the primary cleaning fluid is ejected from the nozzle 22, but this can be compensated for by adjusting the length of the primary cleaning region. Is.

C. Air is used as the primary cleaning fluid instead of liquid, and water is used as the secondary cleaning fluid. In this case, air is used as the replacement fluid in the idle running region F to discharge the water remaining in the nozzle 22 and the nozzle pipe 24 to empty it. When performing such a cleaning process, air is jetted to the container 20 in the primary cleaning area B to blow away dust and dirt, and then the secondary cleaning area C is used.
In the conventional device, the remaining water is sprayed on the container before the air is sprayed in the primary cleaning area, so that dust and dirt adhere to the container 20. Therefore, there is a problem that it is impossible to be blown away by the air, but according to the present invention, water is not sprayed before the air is blown out, so dust and the like are always blown by the air. After being blown off, cleaning is performed with water, and an excellent cleaning effect can be achieved.

D. 50 ° C-60 as primary cleaning fluid
Circulating water at a temperature of C and hot water for finishing at 85 ° C are used as a secondary cleaning fluid. Then, in the idle running region F, circulating water having a temperature of 50 ° C. to 60 ° C. which is the primary cleaning fluid is sent to 85 ° as the secondary cleaning fluid remaining in the nozzle 22 and the nozzle pipe 24. The warm water for finishing of C is replaced. Alternatively, by feeding air in the idle region F, the secondary cleaning fluid remaining in the nozzle 22 and the nozzle pipe 24 is discharged to empty the inside thereof.

E. Steam is used as the primary cleaning fluid, and hot air is used as the secondary cleaning fluid. Also, the container 20
In the idle running region F where the air is supplied and discharged, steam that is a primary cleaning fluid is supplied to the nozzle 22 and the nozzle pipe 2.
The hot air remaining in 4 was replaced with steam. Also in this case, in the primary cleaning region B for the next container 20, steam can be sprayed onto the container 20 at the same time as the start of cleaning.

As another embodiment, as in the conventional cleaning device described in the above publication (Japanese Patent Publication No. 5-85227), the circulating water recovered after being sprayed into the container 20 as the primary cleaning fluid is used. And using clear water as the secondary cleaning fluid. Further, the fixed plate 32 and the intermediate plate 30
In addition, the first and second elongated holes 32a, 32b and the first, second
In addition to the second arc-shaped through passages 30a and 30b, another third long hole and a third through passage are formed in a portion located in the drainage region D (see FIG. 1). Draining is performed by blowing air through the through passage. Then, in the idle running region F, the primary cleaning fluid is fed. With this configuration, by sending air to the nozzle 22 and the nozzle pipe 24 in the draining region D,
After completion of the secondary cleaning, the remaining clean water is discharged and the nozzle 2
After the nozzle 2 and the nozzle pipe 24 are emptied, the nozzle 22 and the nozzle pipe 24 are filled with the primary cleaning fluid, so that an accurate cleaning region is secured in the primary cleaning region B for the next cleaning. be able to.
