Description

washing machine

The present invention relates to a cleaning machine, for example, a vehicle part formed from a metal material, a plastic material, a ceramic material, and machined or molded as an object to be cleaned (hereinafter also referred to as “work”), The present invention relates to a washing machine for washing various parts such as machine parts and precision parts. The present invention is particularly suitable for a cleaning machine suitable for carrying out an efficient cleaning without leaving a residue on a workpiece having a complicated uneven shape including a step part, a groove part, a hole part, a notch part, a gap, and the like. About.

Generally, even during machining, for example, chips and chips are generated during cutting, and the generated chips and chips adhere to the workpiece if left as it is, causing defective products. . Further, since cutting oil is usually used in the cutting process, chips and chips are likely to adhere to the workpiece by the cutting oil. Therefore, after cutting, it is necessary to clean the workpiece and remove chips and chips together with the cutting oil from the workpiece.
Therefore, conventionally, a cleaning liquid spray nozzle for spraying a cleaning liquid and an air spray nozzle for spraying air are arranged around a work (object to be cleaned) so that the cleaning liquid and air are sprayed toward the work. A so-called injection-type workpiece cleaning apparatus configured as described above is known.

However, with this spray type workpiece cleaning device, cutting oil or cutting is required for workpieces with complex irregularities, including parts with varying shapes such as steps, grooves, holes, notches, and gaps. Foreign matter such as powder could not be sufficiently removed, resulting in problems such as uneven cleaning. In this case, in particular, there is a possibility that the cleaning liquid may not sufficiently enter the boundary portion and the peripheral portion where the shape of the uneven shape changes, and as a result, the foreign matter is sufficiently removed by cleaning every corner of the workpiece. It was difficult to do.

Also, as a prior art that is the background of the present invention, a workpiece cleaning apparatus that removes foreign matters adhering to a workpiece having a complicated uneven shape has been proposed (for example, see Patent Document 1). As shown in FIG. 1 of Patent Document 1, the workpiece cleaning apparatus 10 is configured to apply a cleaning liquid toward a workpiece support base 11 that rotatably supports a blade 30 as a workpiece, and the blade 30 supported by the workpiece support base 11. The nozzle 30 is provided with a nozzle 20 that discharges and applies a rotational force to the blade 30 by the discharge pressure of the cleaning liquid, and the blade 30 is cleaned using a centrifugal force generated by the rotation of the blade 30.

That is, in the workpiece cleaning device 10, as shown in FIG. 3A of Patent Document 1, at least one nozzle 20 is disposed below the blade 30 supported by the workpiece support 11 and exposed from the core 33. The cleaning liquid 21 is discharged toward the surface 34 a of the blade portion 34 that performs the cleaning. The point where the cleaning liquid 21 hits the surface 34 a of the blade portion 34 is the contact point P of the cleaning liquid 21.
As a result, the blade 30 is applied with a rotational force by the discharge pressure of the cleaning liquid 21, and rotates in the direction indicated by the arrow in FIG. As the blade 30 rotates, the cleaning liquid 21 hits the blade portions 34 of the blades 30 arranged in the circumferential direction. Further, a part of the cleaning liquid 21 that hits the surface 34a of the blade part 34 also scatters to the back surface 34b of the adjacent blade part 34 as shown in FIG.
Further, as shown in FIG. 3B, the cleaning liquid 21 that has hit the surface 34a of the blade 34 moves the surface 34a of the blade 34 from the radially outer side (contact point P) toward the radially inner side by the discharge pressure. The foreign matter adhering to the surface 34 a is removed by the physical cleaning power and the chemical cleaning power of the cleaning liquid 21 by the discharge pressure of the cleaning liquid 21. Thereby, the first cleaning is performed.

Further, since the blade 30 is rotating, centrifugal force acts on the cleaning liquid 21 that flows radially inward on the surface 34a of the blade portion 34. Therefore, the cleaning liquid 21 flowing inward in the radial direction is eventually reversed in flow direction, and flows on the surface 34a of the blade 34 from the radially inner side toward the radially outer side as shown in FIG. Foreign matter adhering to the surface 34a is removed. Thereby, the second cleaning is performed.
Further, the cleaning liquid 21 which hits the front surface 34a of the blade portion 34 and scatters on the back surface 34b of the adjacent blade portion 34 causes the back surface 34b of the blade portion 34 to radially inward by the action of centrifugal force, as shown in FIG. The foreign matter that flows toward the outside in the radial direction and adheres to the back surface 34b is removed and cleaned.

According to this conventional workpiece cleaning apparatus 10, the discharged cleaning liquid 21 flows radially inward from the contact point P with the blade 30, and then flows again through the contact point P due to the centrifugal force generated by the rotation of the blade 30. After the first cleaning is performed by the pressure of the cleaning liquid 21, the second cleaning is performed by the cleaning liquid 21 that flows by centrifugal force, and the blade 30 can be cleaned twice. It can be removed well.

On the other hand, there is also known a robot cleaning apparatus in which a spray device for injecting a cleaning liquid is attached to the arm tip. In this robot cleaning device, the nozzle body of the spray device has a plurality of nozzle chips with different spray patterns and spray angles, and each nozzle chip is sprayed with a cleaning liquid from nozzle chips with a desired spray pattern and spray angle. It has means for controlling the opening and closing of the connected liquid supply pipe (for example, see Patent Document 2).
In this conventional robot cleaning apparatus, the robot cleaning apparatus is installed at a predetermined position, the robot cleaning apparatus is operated, and the spray apparatus is positioned at a predetermined washable location according to a preset program. Next, in accordance with the degree and range of dirt, the liquid feed pipe connected to the nozzle tip in a desired jetting pattern and jetting direction is opened, and cleaning is performed by jetting cleaning liquid from the nozzle tip. .
