〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the cleaning method of the present invention for cleaning tableware, bucket-shaped food cans with lids for storing cooked food, tableware, baskets for storing spoons, etc. will be further disclosed with reference to the accompanying drawings.

FIG. 1 shows an example of a cleaning apparatus for cleaning objects to be cleaned, such as tableware, food cans, baskets, etc., used in the method of the present invention.

In the storage body 1, in order to form the carrying-in means and the carrying-out means as continuous, one end is a carrying-in port 2, and the other end is a carrying-in port 3.
A continuous transfer path 4 for the object to be cleaned B is formed between the carry-in port 2 and the carry-out port 3 for 6 seconds.

The transfer path 4 has an inclined surface 5 formed downward from the carrying-in port 2, and an upper conveyor 6' ascends toward the method of transferring the object to be cleaned B between the vicinity of the lower end of the inclined surface 5 and the vicinity of the carrying-out port 3. It consists of an endless rotary conveyor 6, such as a chain conveyor, net conveyor, belt conveyor, etc., installed as shown in FIG.

Here, when the inclined surface 5 and the whole or a part of the conveyor 6 are completely located inside, and the object B to be cleaned is placed on the upper conveyor 6 as shown in the figure, at least at the lowermost position of the conveyor 6, An immersion tank 8 containing the cleaning liquid 7 is formed in the interior with a depth that allows the object to be cleaned B to completely settle, and a immersion tank 8 is placed above the immersion tank 8 and at a suitable location in the storage body 1 to the immersion tank 8. The shower nozzle 9 is positioned toward the camera.

Here, in the illustrated apparatus A, when the object to be cleaned B is transferred by the conveyor 6, the object to be cleaned is placed near the transfer route of the conveyor, for example, in the case of the illustrated apparatus, on the side of the outlet 3 of the dipping tank 8. A limit switch may be provided at a suitable position on the vertical wall 8' where the object to be cleaned B that is being transferred contacts.Also, the nozzle or bipup tip is positioned toward the immersion tank 8, and the liquid or gas is It is also possible to forcibly generate a water flow in the cleaning liquid 7 in the immersion tank 8 by spraying water, and to provide waterproof curtains (not shown) at the entrance 2 and the exit 3.

Furthermore, in the illustrated example, the shower nozzle 9 is installed over the entire upper surface of the immersion tank 8;
The shower nozzle 9 is arranged so that the cleaning water is sprayed only on the upper surface of the area that has a depth that allows the object to be cleaned B to completely settle therein.
The cleaning liquid 7 overflowing from the immersion tank 8 may be filtered through a filter and injected from the shower nozzle 9, or a gas such as compressed air may be injected from the nozzle 9.

In this way, a limit switch is provided so that the object B to be cleaned is 8
If the drive of the conveyor 6 is stopped when it comes into contact with the wafer, even if a trouble occurs in the immersion tank 8, damage to the device A and the items to be cleaned B can be prevented. If a separate means for forcibly generating a water flow is provided in the dipping tank 8, it will be more effective in washing away the residue of the object B to be washed.

In addition, if a waterproof curtain is provided, when using mainly hot water for cleaning, hot air containing a large amount of water vapor will flow out of the storage body 1, which will deteriorate the working environment at the location where the device A is installed. If this is prevented, the overflowing cleaning liquid 7 is filtered and sprayed from the shower nozzle 9, and the cleaning water is circulated, the amount of water used can be reduced and the operating cost of the device A can be estimated at a lower cost.

Using such a cleaning device A, tableware 10 made of synthetic resin, such as polypropylene, which has a specific gravity smaller than that of water, as the object to be cleaned B with residue attached thereto, is carried into a Konkure basket 11 through the loading port 2. An example of when this is done will be explained below.

When the basket 11 containing the tableware 10 is carried in from the entrance 2 by an automatic conveyor such as a heald conveyor (not shown) or manually, the basket 11 falls down the slope 5 and onto the upper conveyor 6' at the lowest position of the conveyor 6. It is placed in a completely settled state. At this time, the tableware 10 is removed from the basket 11, and items floating on the surface of the cleaning liquid are washed away.

While the basket 11 is being transported by the conveyor 6 toward the outlet 3, the water flow generated in the cleaning liquid 7 of the dipping tank 8 by the cleaning water sprayed from the shower nozzle 9, or the above-mentioned water flow that is separately provided in the dipping tank 8. It is washed by a water stream generated by a suitable water stream generating means.

In addition, the tableware 10 floating on the surface of the cleaning liquid 7 is forcibly settled in the cleaning liquid 7 by the cleaning water jetted from the shower nozzle 9, and while being washed by the water flow, the basket 11 which settles due to its own weight is The liquid to be cleaned 7 moves to the general outlet 3 side near the surface by the water flow as it is transferred to the outlet 3 by the conveyor 6, and is placed on the conveyor 6 rising in the transfer direction or on the upper conveyor 6'. While being caught in the basket 11, the vehicle is guided toward the three general exits.

Then, the cleaned basket 1 is generally taken out from the carry-out port 3.
] and tableware 10 are suitably subjected to a main washing process, finished washing, dried, and used again.

If the cleaning device A is used as described above, when tableware, food cans, baskets, etc. are simultaneously carried into the dipping tank 8 containing the cleaning liquid 7,
Cleaning liquid can also be used when the opening side of a bowl-shaped food can is facing downward, when the storage side of plate-shaped tableware is facing upward, or when using tableware made of polypropylene, which has a specific gravity lower than that of water. 7, and a good cleaning effect can be obtained.

Furthermore, for example, as a conventional cleaning apparatus having this type of infiltration tank a, there is a cleaning apparatus as shown in FIG.
In this device, there is an inlet side lift (f) for carrying the object to be cleaned into the cleaning liquid d in the immersion tank a near the carry-in port C, and a lift for carrying the object to be cleaned from the cleaning liquid d near the carry-out port g. Not only is the exit side lift (h) required separately in addition to the net conveyor i as a transfer means, but also the lifts f and h move up and down, which has the disadvantage that loading and unloading operations are intermittent. According to the device A of the invention, such a lift f,
h is also unnecessary, and furthermore, the cleaning work can be carried out efficiently because the work can be done continuously.

〔Effect of the invention〕

According to the method for washing tableware, food cans, baskets, etc. of the present invention as described above, the objects to be washed having different shapes and the objects to be washed made of materials with different specific gravity are simultaneously filled with cleaning liquid using the carrying means. ? -x? Even if there is something floating on the surface of the cleaning solution when it is carried into tank B, it will be forcibly settled into the liquid by spraying liquid or gas from above the immersion tank. The cleaning effect is sufficiently exerted even on the parts of the object to be cleaned that protrude from the surface of the cleaning liquid.

Furthermore, since the liquid or gas is injected onto the surface of the cleaning liquid, the surface of the liquid vibrates, and the object to be cleaned can be cleaned without using a separate means for generating a water flow within the cleaning liquid.
