Detailed Description of the Invention

[0001]

The present invention relates to relates to cleaning apparatus for cleaning industrial products and tableware of any object to be cleaned such as metal processing parts and plastics moldings.

[0002]

2. Description of the Related Art For example, metal working parts formed by press working have oil adhered thereto after press molding,
In order to remove the oil, it is immersed in a cleaning solution for cleaning. Conventionally, a rotating drum type cleaning device has been developed for automatically cleaning such metal-worked parts. In this cleaning device, a large number of metal-working parts (workpieces) to be cleaned are put into a cylindrical rotary drum, and the rotary drum for cleaning is immersed in a cleaning liquid and rotated to clean the workpiece. .

Further, in this type of metalworking component cleaning apparatus, a draining process and a drying process are usually additionally provided for drying the work after the cleaning process. In order to process these series of steps, a cleaning device has been developed, which is provided with a cleaning, draining and drying section continuously so that a work is sequentially sent to each section. According to this apparatus, the work is fed to the next process while washing the work by the work feeding means or mechanism provided in the rotary drum, whereby the washing and the drying can be collectively performed.

[0004]

By the way, in the conventional cleaning apparatus, in order to shift from the cleaning step to the drying step,
For example, a rotating drum for cleaning is particularly arranged so as to be inclined upward so that the work is floated from the cleaning tank while being fed in the rotating drum. However, when the floated work is processed in the next draining and drying section, the arrangement angle of the device is different between the cleaning process and the drying process, which complicates the connection structure between the processes and makes the entire device larger. There was a problem such as no.

In the conventional cleaning device, depending on the shape of the work, such as a complicated or irregular concavo-convex shape, it may not be possible to perform sufficient cleaning while the work is fed by the work feeding means in the rotary drum. The detergency was lowered and it was practically difficult to perform precision cleaning .

In view of the above points, an object of the present invention is to provide a cleaning device that achieves a high cleaning effect with a compact structure.
