A liquid cleaning area is provided as a cleaning liquid reservoir in which a predetermined height portion of the spiral transfer path can be immersed, and a feeding pipe for the vapor of the cleaning liquid is opened at the upper end opening of the ball. The inside of the bowl where a predetermined height portion of the spiral transfer path above the cleaning area exists is the steam cleaning area, which is the condensation area of the steam, and the inside of the ball where the spiral transfer path portion extending to the opening of the ball above the cleaning area exists. is used as a drying area for the cleaning liquid.

Function Since the present invention has the above-mentioned configuration, the object to be cleaned first undergoes liquid cleaning of oil and fat in the liquid cleaning area, and then is transferred to the steam cleaning area where it comes into contact with the vapor of the cleaning liquid.
The object to be cleaned is cleaned with a liquid that does not contain any oil or fat produced by the condensation of steam on the surface of the object to be cleaned, the remaining oil or fat is removed by dripping the liquid, and then dried in a drying area before being sent out of the vibration cleaning equipment. It can be done.

As a result, oil and fats, etc., are completely removed from the object to be cleaned in one step.

Embodiment FIG. 1 is a longitudinal cross-sectional view of a first embodiment, in which a vibrating parts feeder 1 for small articles such as screws to be cleaned has a vibrating part 2 and a micro-vibration applied by the vibrating part 2. The inner peripheral wall of the ball 3 has a lower bottom portion 4.
A spiral transfer path 6 is formed from the top toward the upper end opening 5.

An inverted truncated conical cylindrical hopper 7 is disposed in a portion of the inner cavity of the ball 3 surrounded by the spiral transfer path 6, and a cooling tank 8 is integrally formed on the peripheral wall of the hopper 7. There is. The hopper 7 is fixed to an outlet interval adjustment knob 9, and by raising and lowering the knob 9 in the direction of the double arrow A and fixing its position, the interval between the outlet 10 and the lower bottom 4 of the ball 3 is adjusted. The height can be adjusted to suit the size of the object to be cleaned.

A cleaning liquid discharge port 11 is opened at a predetermined height H above the lower bottom portion 4 of the ball 3, and a portion between the lower edge of the discharge port 11 and the lower bottom portion 4 is used as a storage portion for the cleaning liquid. A predetermined height of the transfer path 6, that is, a portion corresponding to the height H is immersed in the stored cleaning liquid, and this portion is used as the liquid cleaning area 12 of the object to be cleaned.
It is said that The height H, which is the height of the liquid cleaning area 12, is optimally selected depending on the size of the object to be cleaned, the amount of liquid to be present in the liquid cleaning area 12, the time, etc. The position may be adjusted up and down.

As the above-mentioned cleaning liquid, 1,1,1-trichloroethane is used to clean oils and fats adhering to metal products, but it goes without saying that other cleaning liquids may be used as long as they have a low boiling point. be.

A steam pipe 39 is disposed at the upper end opening 5 of the ball 3, facing the spiral transfer path 6, and for spouting the steam of the cleaning liquid into the ball 3. The steam of the cleaning liquid ejected from the steam pipe 12 into the ball 3 passes downward between the outer peripheral surface of the cooling tank 8 of the hopper 7 and the spiral transfer path 6, as shown by arrows B and C. A predetermined height portion L above a portion corresponding to the height H of the spiral transfer path 6 in the cleaning liquid area 12
It accumulates in the ball 3 where it exists, gradually condenses, and drips toward the bottom 4 of the ball 3.

As mentioned above, since the cooling tank 8 is attached to the hopper 7, the above-mentioned condensation of the vapor is facilitated, and as will be explained later, the vapor rises from the liquid cleaning area 12 along the spiral transfer path 6. Most of the steam is condensed when it comes into contact with the surface of the object to be cleaned, and the steam that condenses on the surface of the object and becomes the cleaning liquid again does not contain any oil or fat. Since it is a pure cleaning liquid, when it is dripped, oils and fats on the surface of the object to be cleaned are completely cleaned and removed.

The predetermined height portion L in the ball 3 described above is
A steam cleaning area 13 is formed by the condensation of the steam and the accompanying cleaning action.

Inside the bowl 3, where the spiral transfer path 6 from the steam cleaning area 13 to the upper end opening 5 of the bowl 3 exists,
This is a drying area 14 where the cleaning liquid adhering to the surface of the object to be cleaned is vaporized. The cleaning solution is the one mentioned above.
If the liquid has a low boiling point of about 74°C, such as 1,1-trichloroethane, the upper end opening 5 of the ball 3 can be adjusted by selecting the length of the spiral transfer path 6 in the drying area 14. The items to be cleaned that come out are completely dry.

In FIG. 1, reference numeral 15 is a cooling water inlet, and reference numeral 16 is a cooling water outlet.

Since the vibration cleaning apparatus according to the present invention has the above-mentioned configuration, the object to be cleaned is washed in the liquid in the liquid cleaning area including the bottom of the ball of the vibrating parts feeder, and the object to be cleaned is washed by the steam in the spiral transfer path above the liquid cleaning area. When the object moves to the cleaning area, it comes into contact with the vapor of the cleaning liquid, condenses on the surface of the object, and is re-cleaned with the liquefied clean condensate, undergoing so-called steam cleaning, and then passing through the liquid cleaning area. The cleaning liquid film containing some oil and fat adhering to the surface of the object transferred to the steam cleaning area is cleaned and removed.

The material is then dried in a drying area with a spiral transfer path above the steam cleaning area.

Therefore, if the vibration cleaning device according to the present invention is placed adjacent to the manufacturing equipment for small items such as screws, the small items will be transferred to the cleaning process that is continuous with the manufacturing process, reducing the equipment area and reducing production. This can improve efficiency.

Effects The present invention has the configuration and operation described above, and the object to be cleaned is cleaned in the liquid cleaning area provided at the lower part of the ball of the vibrating parts feeder.
The object is immersed in the cleaning liquid to undergo liquid cleaning, and is then sent along a spiral transfer path to an upper steam cleaning area, where it comes into contact with clean cleaning liquid vapor, and the surface of the object to be cleaned is condensed and liquefied, resulting in cleaning. By dropping the condensate, the cleaning liquid film adhering to the surface is cleaned and removed when moving from the liquid cleaning area to the steam cleaning area, and the surface is dried in a clean state. This has the effect of completely removing oil and fat from the surface of the object to be cleaned.

Furthermore, since the equipment can be of relatively simple structure, it can be placed so as to be directly connected to the manufacturing equipment for small items, and the installation area of the equipment can be relatively small. It can also be omitted, which has the effect of improving productivity.
