Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerial underwater cleaning apparatus belonging to a type for performing cleaning by rotating a cleaning object.

[0002]

2. Description of the Related Art When a metal product is finished by machining, it is necessary to remove the chips and cutting oil generated by the processing because the product adheres to the product. For example, a cylinder head or a cylinder block of an engine corresponds to the above products. There is a problem that it is not always easy to completely remove the swarf because the swarf adheres to each part formed in the product or enters a hole.

[0003] In particular, in the case of aluminum products, since the specific gravity is lighter than the swarf coming out of the cast iron block, it is difficult to sink and the handling is troublesome. As a result, extra cleaning time is required, and the amount of power used and the amount of cleaning liquid used also increase. In the case of the aforementioned engine block, the time required for cleaning directly affects the speed of the production line.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to quickly and surely remove chips, cutting oil and other deposits generated in cutting and the like from a cleaning object. To be removed.

Another object of the present invention is to prevent foreign substances of a previous cleaning object from re-adhering to a subsequent cleaning object by eliminating residues in the cleaning liquid.

[0006]

Means for Solving the Problems] to resolve the above problems
Because the onset Ming, injection of the cleaning liquid against the cleaned washing was held at both longitudinal ends Te by rotating arm, and a holding means for moving from the outside of the cleaning chamber to the inside of the cleaning position, the cleaning chamber performs air cleaning by morphism, its
The washed product meets the cleaning chamber by the rear the washing solution and submerged state, if row water washed by morphism injection of cleaning fluid
A cleaning nozzle and a drain port for discharging all the cleaning liquid from the cleaning chamber
In this case, a means of having a configuration having the following is taken.

Further, the cleaning object moved from the cleaning chamber to the drying chamber is rotated by a rotating arm of another holding means to drain water, and the cleaning object is dried by injecting a drying gas from a nozzle. Can be added.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A cleaning object rotating type underwater washing apparatus according to the present invention means an apparatus having a type and a structure for rotating and cleaning a cleaning object.

By rotating the cleaning object, the cleaning liquid can be effectively sprayed on the entire surface even when the cleaning nozzle is fixed. In addition, a centrifugal force can be expected in order to constantly discharge, for example, cutting chips, cutting oil, dust, and other foreign substances adhering to the cleaning object outside the cleaning object by the rotation of the cleaning object.
Further, since the cleaning object itself is rotated, the cleaning liquid to be sprayed collides with the cleaning object from various angles, and the cleaning liquid has a complicated effect, so that the cleaning power is enhanced.

In the above, the air washing and the underwater washing are defined as
It is performed one after another in the same washing room. In the early stage of the air cleaning, the cleaning liquid is discharged without being stored, and the cleaning liquid is stored when it is possible to shift from the air cleaning to the underwater cleaning.
The cleaning object is immersed in the liquid. In the underwater cleaning, the cleaning liquid is sprayed from the cleaning nozzle to clean the cleaning object. At that time, since a large amount of air bubbles can be carried to the target position together with the cleaning liquid, a remarkable cleaning effect is exerted by cavitation, shot blast action accompanying the burst of air bubbles, and the like.

The cleaning object is transported to the cleaning chamber by the transport means, which is held at both ends in the longitudinal direction by the rotating arms of the holding means. In order to rotate the cleaning object, the cleaning object is held at both ends in the longitudinal direction, so that the radius of rotation of the cleaning object and therefore the rotational moment can be small.
Also, the power required for rotation may be relatively small, and the washing liquid is not agitated more than necessary in the case of submerged washing.

[0012] The holding means is means for holding the cleaning object and moving it to the cleaning position in the cleaning chamber. The rotating arm of the holding means is openable and closable for holding the washing object, and is capable of holding and moving the washing object to the washing position, and is also capable of rotating the washing object.

The cleaning object held rotatably by the holding means is cleaned by jetting a cleaning liquid at a high pressure and a low pressure from each cleaning nozzle. In the present invention, the cleaning that receives the injection of the cleaning liquid in the air is referred to as air cleaning. The cleaning nozzle sprays the cleaning liquid on the cleaning object.
The nozzle may be movable or fixed. In the case of the movable type, an even more complicated action occurs with the rotating cleaning object. Further, by blowing air bubbles from below on the cleaning object in the liquid by the aeration nozzle, the cleaning power is further enhanced.

The washing liquid is preferably water or a washing liquid mainly composed of water. By using water or a cleaning solution mainly composed of water, a harmful cleaning agent such as an organic solvent is not required, and no special wastewater treatment is required, and the working environment can be suitably maintained. In the case of a cleaning solution mainly composed of water, a rust preventive or a non-hazardous clearing agent such as an alkaline detergent can be used as necessary to prevent the generation of rust due to water cleaning.

The cleaning nozzle simply jets a cleaning liquid at a high or low pressure, creates a negative pressure by high-pressure water injection, sucks an air flow or a low-pressure water flow by the negative pressure, and mixes bubbles in the high-pressure water flow. What ejects a fluid is used.

Such a washing nozzle is disclosed in Japanese Patent No. 27070.
No. 90, etc., are used in a series of inventions of the present inventor, and have obtained remarkable effects. This nozzle also works effectively in the present invention.

In the cleaning room where the air cleaning has been performed, extraneous matter that has already been washed away is discharged, and the cleaning room is filled with a cleaning liquid, and the cleaning material is brought into a submerged state. In the submerged state, the cleaning liquid is sprayed from the cleaning nozzle onto the cleaning object, thereby performing underwater cleaning. Therefore, a relatively large amount of the cleaning liquid is used for the residue of the dirt washed off by the air cleaning, and the ideal cleaning is completed after the completion of the cleaning step of discharging the entire cleaning liquid from the cleaning chamber.

First and second two sets are prepared for the holding means.
The first holding means can be applied to handling (holding, moving, rotating) of the cleaning object in the washing chamber, and the second holding means can be applied to similar handling in the drying chamber.

The second holding means is a means for applying a rotation to the cleaning object moved from the cleaning chamber to the drying chamber to drain the water. This draining is also performed by the centrifugal force caused by the rotation of the cleaning object, and at the same time, the drying gas is jetted from the nozzle to the cleaning object, whereby the drying of the cleaning object is quickly completed. For this reason, even if there is a portion where water is likely to remain on the cleaning object, such as a screwed portion, the moisture is effectively removed, so that there is no rust.

In order to transport the cleaning object 10, transporting means 17 and 18, which are roller conveyors, are provided at the loading section 11 and the transporting section 16, respectively.
3, a main transport unit 19 including a chain (or an endless belt) and other annular transport belts is provided up to the drying chamber 14 and the rear deflection unit 15.

The front and rear transport means 17 and 18 are means for carrying the cleaning object 10 into and out of the apparatus, but if the same purpose can be achieved, a different conveyor line from the apparatus. May be used. Main transport means 1
Numeral 9 denotes a means for transporting the cleaning object 10 between the front and rear deflection parts, and has a width capable of mounting the cleaning object 10 that has been turned sideways.

The cleaning object 10 is transferred from the carry-in section 11 to the front turning section 12.
A turning conveyor 20 is installed in order to change the direction and transfer. The illustrated diverting conveyor 20 is of a hanging type that holds the cleaning object 10, lifts it by an elevator 21, and changes its direction around a vertical axis 22. The conveyer 20 reciprocates between the two sections by a guide mechanism installed from the loading section 11 to the front turning section 12.

The cleaning object 10 whose direction has been changed is the front turning portion 1.
2 to the cleaning chamber 13 by the main transport means 19.
The drying chamber 14 adjacent to the cleaning chamber 13 is a closed space in which the cleaning liquid and its splash do not leak to the outside. Each room 1
The doors 3 and 14 are opened and closed by doors 23, 24 and 25, respectively. The bottom is provided with an inclined drainage structure capable of quickly discharging a large amount of drainage. Reference numerals 26, 27, 28 denote switches for each door, and 29a denotes a large-diameter drain port. Reference numeral 29b denotes the inclined bottom surface for guiding drainage to a drain outlet 29a. See FIG.

The first holding means 30 having a rotating arm for holding the cleaning object 10 is provided with an elevator 31 above the cleaning chamber 13.
It is installed so that it can go up and down. The first holding means 30 has a frame 32 suspended from an elevator 31 and has a pair of rotating arms for holding the cleaning object 10 at both ends in the longitudinal direction. The rotating arm has a pair of hanging arms 33, 34 provided downward at a required interval, and clamps 35 capable of holding the cleaning object 10 are coaxially provided at the distal ends of the arms 33, 34, respectively. It is provided rotatably. See FIG. 5 and FIG.

A rotation source 36 for driving the clamps 35, 35 is mounted on the frame 32, and has a transmission shaft comprising a clamp shaft 37, a sprocket, a chain, and belts via a relay shaft 38 whose interval can be adjusted on the same shaft. Mechanism 39a, 39
b. 39c and 39d are cylinder devices for adjusting the distance between the suspension arms 33 and 34, and 39e is a sprocket for tensioning chains and belts (39b) in the transmission mechanism. It is pivotally supported and is operated by the adjuster 39g to maintain the above-mentioned degree of tension appropriately.

A cleaning nozzle 40 for injecting a cleaning liquid to the cleaning object 10 set at the cleaning position by the elevator 31 is installed in the cleaning chamber 13. Cleaning nozzle 40
For example, as shown in FIG. 4, by injecting high-pressure water into a cylinder 41 having one end closed and the other end opened, a negative pressure is formed, and the negative pressure causes low-pressure water and gas (air). Good) can be sucked, and a fluid (high-pressure jet water) in which a cleaning liquid and a gas are mixed in a high-pressure water stream can be jetted to the cleaning object. In FIG. 4, reference numeral 42 denotes a high-pressure water injection port, 43 denotes a low-pressure water inlet, and 44 denotes a gas inlet.

With such a nozzle 40, low-pressure water and gas are entrained in high-pressure water, and are jetted as high-pressure jet water having a high kinetic energy onto a cleaning object. When the high-pressure jet stream collides with the object to be cleaned, a peripheral cleaning area is formed around the center wash area where the flow of the liquid containing a large amount of air bubbles separates the adhered substance due to the high-pressure diffuse reflection of the high-pressure jet stream. In addition, a fluid in which a cleaning liquid and a gas are mixed travels along the surface of the cleaning object to cause an interfacial flow, thereby performing a strong cleaning action.

The cleaning liquid jetted from the cleaning nozzle and the like is circulated and used, and its circuit configuration is exemplified as shown in FIG. The cleaning liquid pipe is composed of pipes 45 and 46 of each system having a high-pressure pump and a low-pressure pump. The high-pressure pipe is mainly used for cleaning the cleaning object 10, and the low-pressure pipe is used for introducing the low-pressure water and cleaning the cleaning chamber 13. Supply the cleaning liquid to be used. 4
Reference numeral 0 'denotes a nozzle for aiming a hole for high pressure, which intensively cleans a hole of the cleaning object 10, that is, a through hole or a concave portion.

The cleaning liquid after the cleaning is returned to the circulation tank 1 from the circulation pipe 47. It is assumed that fresh water is automatically supplied to the circulation tank 2. Reference numeral 48 denotes a low-pressure nozzle, and reference numeral 49 denotes an aeration nozzle for cleaning, which blows air from below on a cleaning object in the liquid.

Therefore, the cleaning nozzles 40 and 40 'are of a fixed type which are installed so as to face the cleaning object 10 set at the cleaning position. However, it is of course possible to change the installation positions of the cleaning nozzles 40 and 40 ', and the term "fixed" means that no rotational movement is performed.

After the cleaning, the cleaning object 10 is dehydrated and dried in the adjacent drying room 14. Also in this case, the cleaning object 10 is set to the drying position by the elevator 51, and the second holding means 50
In the state of being rotated and held, the air is received from the drying nozzle 52 and the like. The drying air supplied from the air source is supplied to the drying nozzle 52, and the drying nozzle 52 is used for the whole cleaning object and the partially concentrated work by the hole aiming nozzle 52 'similar to the above.

The second holding means 50 may have exactly the same configuration as that of the first holding means 30 (FIG. 5,
See FIG. ). That is, the cleaning object 10 is raised to the drying position by the second holding means provided in the drying chamber 14 and held by the clamps 35 at the tips of the suspension arms 33 and 34 provided on the frame 32, and the transmission mechanism is provided. The rotation is performed by the transmission of the rotation source 36 connected by 39a and 39b, the droplets are blown off by centrifugal force, and are quickly dried by the dryers sprayed from the drying nozzles 52 and 52 '. Reference numeral 53 denotes a drain port at the bottom of the drying chamber, and the collected cleaning liquid is returned to the circulation pipe 47.

The washed article 10 after drying is conveyed to the rear turning section 15 by the rear turning conveyor 54, and the orientation of the washed article 10 is returned from the horizontal direction to the vertical direction. The rear deflection conveyor 54 has a lift 55 for holding the cleaning object 10 and is of a hanging type that changes its direction around a vertical axis 56. The role and function required of the rear diverter 54 may be the same as those of the front diverter 20.

An inspection unit 57 for taking out the cleaning object 10 to inspect the cleaning quality is provided in the turning unit 15. This is because there is no need to stop the work flow, and it is possible to observe the cleaning state immediately after.

The cleaning object 10 is returned to the vertical position, and is placed on the transporting means 18 of the unloading section 16 by the rear deflection conveyor 54. This transporting means 18 is opposite to that of the loading section 11,
This is for sending the washed object 10 to the next step. Therefore, it is of course possible to use the end of the conveyor line different from the present apparatus as the conveying means 18. In this way, the present apparatus can be arranged at any place on the existing conveyor line.

[0037]
