Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a parts cleaning device used in the process of cleaning and air blowing parts such as gears after shaving.

(Prior Art) On a production line, parts such as gears that have been shaved are cleaned and blown with air before being sent to the next process. Generally, cleaning and air blowing are performed in separate cleaning stations and air blowing stations. In that case, there was a problem in that the space occupied by the device was inevitably large, which became a problem in line design.

(Purpose of the invention) The purpose of the invention is to reduce the space occupied by the apparatus by allowing cleaning and air blowing to be performed at the same station.

(Structure of the invention) The present invention is capable of storing various parts to be cleaned, such as gears after shaving processing, at the bottom of a cleaning chamber that has a cleaning nozzle on the inner wall, and in the cleaning chamber, the inside of the cleaning nozzle A partition cover having an air blow nozzle is provided, and the partition cover is movable up and down between a position above the cleaning nozzle and a position where the object to be cleaned can be covered with a gap interposed between the bottom surface and the cleaning nozzle. The feature is that after cleaning various parts, air can be blown at the same position.

(Example) Hereinafter, a parts cleaning apparatus according to an example of the present invention will be described with reference to the attached drawings.

A cleaning chamber 3 having an opening 4 on the front surface is provided on a base 1 which also serves as a tank 2 for storing a cleaning liquid (for example, an alkaline liquid) L. The opening 4 is provided with an opening/closing door 5.

In the middle of the inner wall 6 of the cleaning chamber 3, cleaning nozzles 7, 7, . . . arranged in an annular manner are provided. The cleaning liquid L is supplied to these cleaning nozzles 7, 7, . . . from the tank 2 through the cleaning pump 8 and filter 9. Reference numeral 10 indicates piping.

An object to be cleaned, for example a gear 12 after being shaved, is housed at the bottom of the cleaning chamber 3 while being placed on a receiver 11 . The receiver 11
can be taken in and out of the cleaning chamber 3 through the opening 4 by means of a transport air cylinder 13.

Further, in the cleaning chamber 3, an air blow nozzle 1 is installed inside the cleaning nozzles 7, 7...
A partition cover 15 having 4, 14, . . . is arranged so as to be able to move up and down.

The partition cover 15 has an air cylinder 16 for lifting and lowering.
Accordingly, it can be raised and lowered between the upper part of the cleaning nozzles 7, 7, .

The descending operation of the partition cover 15 is regulated so that a slight gap S is formed between its lower end and the bottom surface of the cleaning chamber 3 when the partition cover 15 is in its lowest position.

In the drawings, reference numeral 17 is an air pipe, and 18 is a chain conveyor that conveys the object 12 to be cleaned.

The illustrated parts cleaning device operates as follows.

After setting the shaved gear 12 conveyed by the chain conveyor 18 on the receiver 11 and storing it in the inner bottom of the cleaning chamber 3 by the conveying air cylinder 13, first, the cleaning nozzles 7, 7 Cleaning is performed by the cleaning liquid L spouted from . At this time, the partition cover 15 is positioned above the cleaning nozzles 7, 7, . . . as shown by the solid line. After cleaning is completed, the lifting air cylinder 16 is operated to lower the partition cover 15 as shown by the dotted line to cover the gear 12, and in this state, the air blowing nozzle 14, 14... Blow off water droplets attached to gear 12. At this time, the air containing the blown water droplets is discharged outward from the gap S at the bottom of the partition cover 15, so that it does not adhere to the gear 12 again.

After the air blow is finished, the partition cover 15 is raised, and the gear 12 is moved by the conveying air cylinder 13.
Take it out and finish the work.

(Effects of the invention) Next, the effects of the parts cleaning device of the invention will be described.

According to the present invention, a partition cover having an air blow nozzle is provided inside the cleaning nozzle in the cleaning chamber so that it can be raised and lowered, so that cleaning and air blowing can be performed at the same position, which is different from the conventional separate Compared to what would be done at a station, the space occupied by the equipment can be greatly reduced, which has the practical effect of making production line design easier.

In addition, the partition cover is designed to cover the object to be cleaned with a gap between it and the bottom of the cleaning chamber when it is lowered, so that when air is blown, air containing water droplets will flow out of the partition cover. There is also the advantage that re-adhesion to the object to be cleaned can be effectively prevented.
