Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for cleaning objects to be cleaned such as industrial products such as metal processed parts and molded plastics, tableware, and foods such as fruits and grains.

[0002]

2. Description of the Related Art For example, oil is adhered to a metal work part formed by press working or the like after press forming.
In order to remove the oil, it is immersed in a cleaning solution for cleaning. Conventionally, a rotating drum type cleaning apparatus has been developed to automatically clean such metal processing parts. In this cleaning apparatus, a large number of metal processing parts (works) to be cleaned are put into a cylindrical rotary drum, and the workpiece is cleaned by immersing the cleaning rotary drum in a cleaning liquid and rotating the cleaning drum. .

[0003] Further, in this type of cleaning apparatus for metal working parts, a draining step and a drying step are usually added to dry the work after the cleaning step. In order to process these series of processes, a cleaning apparatus has been developed which is continuously provided with a cleaning, draining and drying section, and is configured to sequentially feed a work to each section. According to this apparatus, the work is sent to the next step while washing the work by the work sending means or mechanism provided in the rotary drum, whereby the washing and drying can be performed collectively.

[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 to be inclined upward, so that the work floats from the washing tank while being fed in the rotating drum. However, when the floated workpiece is processed in the next draining and drying section, the arrangement angle of the apparatus is different between the washing step and the drying step, so that the connection structure between the steps is complicated, and the entire apparatus must be enlarged. There was no problem.

[0005] Further, in the conventional cleaning device, depending on the shape of the work, for example, complicated or irregular uneven shape, etc., it may not be possible to sufficiently clean the work while being sent by the work feeding means in the rotary drum. Detergency deteriorated and precision cleaning was substantially difficult. In the above description, an example was given in the case of cleaning a metal work part (work), but in addition, cleaning for disinfecting fruits and grains, removing disinfectants, or cleaning tableware and other articles. The above-mentioned cleaning apparatus is widely used for such as,
There are exactly the same problems when cleaning these various objects to be cleaned.

[0006] In view of the above, an object of the present invention is to provide a cleaning apparatus which achieves a high cleaning effect with a compact configuration.

[0007]

According to a first aspect of the present invention, there is provided a cleaning apparatus comprising: a cleaning rotary drum; and a draining rotary drum connected to the cleaning drum. A spiral feed fin is formed on the inner peripheral surface, and the washing rotary drum and the draining rotary drum are arranged along a horizontal coaxial axis.

[0008] The cleaning device according to the second aspect of the present invention integrally includes a cleaning unit having a rotating drum having a sequentially reduced diameter, a draining unit, and a drying unit, and has a spiral feed fin that is continuous on the inner peripheral surface of each rotating drum. The washing unit, the draining unit, and the drying unit are horizontally arranged along a horizontal coaxial axis. Further, in the cleaning apparatus of the present invention, the large-diameter rotary drum for cleaning and the small-diameter rotary drum for drying are connected via a rotary drum for draining, and only the rotary drum for cleaning is immersed in the cleaning liquid. It is characterized by. In the cleaning device of the present invention, the rotating drum for draining is tapered toward the drying section. Further, in the cleaning device of the present invention, preferably or as necessary, a plurality of small projections may be provided on each of the inner peripheral surface of each rotating drum and the side surface of the feed fin. Further, in the cleaning device of the present invention, an ultrasonic oscillator may be installed at an appropriate position below the cleaning rotary drum. Further, a shower device can be provided in the washing rotary drum.

According to the first aspect of the present invention, the draining rotary drum connected to the cleaning rotary drum is formed to have a tapered diameter, and a spiral feed fin is formed on the inner peripheral surface thereof. The rotating drum for washing and the rotating drum for draining are arranged along a horizontal coaxial axis, so that the rotating drums integrated in series are operated in a horizontal state without tilting. According to the second aspect of the present invention, the diameters of the washing, draining and drying rotary drums respectively arranged in the washing section, the draining section and the drying section are sequentially set to be smaller, and each of these rotary drums is set. Are arranged along a horizontal coaxial axis, so that the washing, draining and drying rotary drums integrated in series are operated in a horizontal state without tilting. In this manner, the large-diameter washing rotary drum and the small-diameter drying rotary drum are connected via the tapered draining rotary drum having a large diameter at the base end and a small diameter at the distal end, thereby reducing the time between processes. The entire apparatus including the washing process to the drying process can be horizontally arranged without requiring a complicated connection structure. Therefore, according to the present invention, a series of processes can be collectively processed while the device is configured compactly. Therefore, since the devices are horizontally arranged in-line, it is easy to connect with subsequent processes. Can be done.

[0010] When the cleaning drum, the draining drum and the drying drum are integrally fed, the object to be cleaned such as a work is turned upside down by a small projection provided in the drum. Is transported repeatedly. As a result, objects to be cleaned such as workpieces can be uniformly cleaned, cleaning performance can be improved, and precision cleaning can be performed.
