In this cleaning device 2, a pair of manifolds 3 are connected to a pipe 4 for supplying cleaning liquid or water, and the manifolds 3 are provided with a cleaning nozzle 5.

This cleaning nozzle 5 is inserted into the opening 1b of the cavity 1a of the box component 1, and the cleaning nozzle 5 is inserted into the pipe 4. The cleaning liquid that has flowed in through the manifold 3 is forced into the cavity la so that foreign matter inside the cavity la is discharged to the outside.

[Problems to be Solved by the Invention] However, in such a conventional method, if the shape inside the cavity 1a becomes compound, it takes time to spread the cleaning liquid and suspend the foreign matter. . ■Cavity part la
There are problems in that it is difficult to create a large flow inside, and there are parts where foreign matter gets stagnant, resulting in poor discharge performance.

Therefore, it is an object of the present invention to provide a method for cleaning box parts that solves the above-mentioned problems.

[Means for Solving the Problem] In order to solve the problem, the present invention provides a cleaning method for cleaning foreign matter in a hollow part of a box part having a hollow part, in which the box part is stored in a tank. In the cleaning solution,
Fill the cavity with cleaning liquid by submerging it in water in an inverted position so that the longitudinal direction of the cavity faces the vertical direction, and then attach an air nozzle to the opening formed at the bottom of the cavity of the box part. The box component is repeatedly supplied and stopped with compressed air into the cavity to forcibly discharge and clean the foreign matter in the cavity, and then the box component is pulled up from the cleaning liquid while applying air pressure inside the cavity. The cleaning method is characterized by:

[Function] According to this method, even if the box part has a complicated shape, it can be easily cleaned by simply submerging the box part in the cleaning liquid.
Moreover, the cleaning liquid can be reliably spread within the cavity.

In addition, the longitudinal direction of the cavity is oriented vertically, and compressed air is supplied from the opening formed at the bottom of this cavity, so in addition to the pressure of the air, buoyancy forces the air to flow upward. A large flow can be created. Therefore, foreign matter within the cavity can be removed more effectively.

[Example] Hereinafter, this invention will be explained based on examples.

FIG. 1 is a diagram showing a first embodiment of the invention.

First, to explain the configuration, the cleaning device 1 used in this invention
1 is configured as follows.

That is, this cleaning device 11 includes a water tank 12 for storing cleaning liquid E, a conveying device 13 for conveying the box component 1 as a box component, and a supply means for supplying compressed air to the cavity 1a of the box component. ] 4.

The water tank 12 has a drain Jl' at the bottom [15 is the hinge 1]
6, and an opening/closing cylinder 17 for opening and closing the water door 15 is also provided.

In addition, the code|symbol 29 is a cleaning liquid E water supply port.

Further, the conveying device 13 has a lifting cylinder 1 mounted on the base 18.
9 is arranged along the vertical direction, and this lifting cylinder 1
A gripping device 21 for gripping the box part 1 is provided at the lower end of the cylinder rod 20 of 9. This gripping device 21 has upper guides 23. Lower guide 2
4 are provided, and a clamper 25 for clamping the box part 1 is disposed therebetween.

Further, the supply means 26 is configured such that a cleaning nozzle 27 is disposed on the lower side of the jig base 22, and a movable tube 28 extending from the outside of the water tank 12 and sending compressed air is connected to the cleaning nozzle 27. has been done.

Using such a cleaning device 11, the cavity 1a of the box part 1 is cleaned.
Clean the inside as follows.

That is, first, the upper and lower guides 23 and 24 of the conveying device 13
With the box part 1 being guided, the box part 1 is held in an inverted state by a clamper 25. In this state, the box part 1 is lowered by the lifting cylinder 19 of the transport device 13, and the box part 1 is completely submerged in the cleaning liquid E. In this state, the box part 1 is turned upside down so that the longitudinal direction of the cavity 1a is directed in the vertical direction. Then, the cavity la of the box part 1 is completely filled with the cleaning liquid E. By submerging the box part l in the cleaning liquid E in this way, the cleaning liquid E is spread throughout the cavity part 1a in a short time. .

After that, compressed air is supplied from the cleaning nozzle 27 via the movable tube 28 to the opening 1b provided on the lower side of the cavity 1a.
The cleaning liquid E is sent into the cavity la through the vacuum cleaner, and air pressure is applied inside the cavity la to forcibly discharge the cleaning liquid E.

After repeatedly supplying and stopping the compressed air, the end part 1 is moved by the lifting cylinder 18 while the air pressure is applied.
At the same time, the jig base 22 is pulled up from the cleaning liquid E and the supply of compressed air is stopped.

In this case, by orienting the longitudinal direction of the cavity 1a in the vertical direction and sending compressed air from the opening 1b provided at the bottom of the cavity 1a, in addition to the pressure of the air, buoyancy causes the cavity to be directed upward. A large flow can be created. Therefore, due to this strong flow, foreign matter in the cavity 1a can be more efficiently discharged.

Next, the drainage group 15 is opened by the opening/closing cylinder 17,
The dirty cleaning liquid E is discharged to the outside of the water tank 12, and after discharge, the drain group 15 is closed.

In such a cleaning device 11, in order to supply the cleaning liquid E, the end part l is simply submerged in the cleaning liquid E. Therefore, as in the past, a complex device for supplying the cleaning liquid E is required. is not necessary.

FIG. 2 shows a second embodiment of the invention.

This embodiment differs from the first embodiment in the configuration of the gripping device 21.

That is, a jig base 31 is attached to the lower end of the cylinder iron 20 of the conveyance device 13 via a stay 30 so as to be rotatable about a shaft 32 . This jig base 3
A spring 33 is interposed between the jig base 31 and the stay 30, which normally biases the jig base 31 into a substantially upright state. Further, a movable rod 34 is protruded from the jig base 31, and the movable rod 34 is provided on the inner wall of the water tank 12.
a fixed rod 3 that makes contact with the jig base 31 and swings the jig base 31;
5 is provided protrudingly.

The other configurations are the same as in the first embodiment.

According to this embodiment, by moving the jig base 22 up and down with the lifting cylinder 19, the movable rod 34 comes into contact with the fixed rod 35, and the end piece 1 swings about the shaft 32. During this rocking, compressed air is repeatedly supplied and stopped from the cleaning nozzle 27 into the cavity la. In this way, foreign matter can be more effectively discharged from the cavity la.

Other operations are the same as those in the first embodiment, so explanations will be omitted.

[Effects of the Invention] As explained above, according to the present invention, since the end parts are submerged in the cleaning liquid, the cleaning liquid is reliably spread within the cavity, and foreign matter can be removed quickly and reliably. be able to. In addition, by orienting the longitudinal direction of the cavity in the vertical direction and sending compressed air from the opening at the bottom of the cavity, the cleaning liquid is directed upward in the longitudinal direction by the buoyancy in addition to the air pressure. Since a powerful flow is generated, the cleaning ability can be further improved, which is a beneficial effect in practical terms.
