Description

  The present invention relates to residual deposits such as metal scraps and resin scraps, glass powder, organic oils and fats adhering to the surface of an object to be cleaned, such as machined parts and machined products (made of metal, resin, etc.) More particularly, the present invention relates to a cleaning device suitable for cleaning an object to be cleaned having a complicated internal structure.

  Conventionally, when cleaning an object to be cleaned having a complicated internal structure, for example, a hole is formed in a circuit shape, a cleaning nozzle is directed toward the inlet of the hole in order to reliably remove the residual foreign matter inside the object. Cleaning was performed by adjusting the position, angle, etc., so that the cleaning liquid could be fed deep into the object to be cleaned. As such a cleaning apparatus that can freely move the cleaning nozzle, there is one disclosed in Patent Document 1.

  On the other hand, as in Patent Document 2, a cleaning device that covers a cylindrical body on a base on which an object to be cleaned is placed and injects a cleaning liquid while rotating a cleaning nozzle member in which a large number of cleaning nozzles are arranged inside the cylindrical body There is also.

JP 2009-275265 A JP 2006-122811 A

  In the case of an object to be cleaned having a complicated structure, 20 to 30 cleaning nozzles may be required in a conventional cleaning apparatus. Further, when cleaning is performed by freely changing the position of the nozzle as in the cleaning device of Patent Document 1, each of as many as 20 to 30 cleaning nozzles depending on the shape of the object to be cleaned (the position of the hole). About the position and angle must be adjusted. If the structures of the objects to be cleaned are different, this operation is performed for each object to be cleaned. Therefore, adjustment of the position and angle of the cleaning nozzle not only requires the skill of the operator, but is also inefficient, and there is a problem that a certain cleaning effect cannot be achieved.

  Further, in the cleaning device of Patent Document 2, it is not necessary to adjust the position and angle of a large number of cleaning nozzles arranged on the cleaning nozzle member rotating inside the cylinder, but the cleaning liquid ejected from one cleaning nozzle is No matter how many rotations it hits the same line on the object to be cleaned. Therefore, depending on the structure of the object to be cleaned, there is a possibility that the cleaning liquid is not sufficiently jetted to a necessary portion. On the other hand, if the number of cleaning nozzles is increased to avoid this, the pressure of the cleaning liquid will decrease, or a large pump will be introduced to maintain the pressure, which may lead to a rise in equipment costs and operating costs. Absent.

  The present invention has been made in view of the above points, and provides a cleaning apparatus that can effectively clean an object to be cleaned with various internal structures with a small number of cleaning nozzles that do not require position and angle adjustment. With the goal.

In order to solve the above problems, a cleaning apparatus according to the present invention is a cleaning apparatus for cleaning an object to be cleaned with a cleaning fluid ejected from a cleaning nozzle,
A cylinder that holds an object to be cleaned and has a size that surrounds the base and the object to be cleaned from above, and a cylinder that can be moved up and down by an elevating drive, A cylindrical container, and a cleaning nozzle fixed toward the inside of the cylindrical body or the side surface of the cylindrical container, and between the peripheral portion of the base and the side wall of the cylindrical body or the cylindrical container And the cylinder or the cylindrical container can move up and down with a predetermined amplitude, and at least one of the rotational speed of the base and the vertical speed of the cylinder or cylindrical container is: It is adjustable.

  Here, the “cylindrical container or cylindrical container” refers to a “cylindrical container” in which both ends of the cylinder are open on the base side (lower side) and not open on the upper side. "" Means that both ends of the cylinder are open.

  According to this configuration, it is possible to simultaneously perform the rotation of the base and the up-and-down movement of the cylindrical body or cylindrical container to which the cleaning nozzle is fixed. As a result, the cleaning fluid (cleaning liquid such as water, air, or a mixed fluid thereof) received by the object to be cleaned from the cleaning nozzle draws a wavy nozzle injection pattern that vibrates with a predetermined amplitude W up and down. (See, for example, FIGS. 4 and 5).

  Therefore, the entire object to be cleaned can be cleaned even with a small number of cleaning nozzles. Adjust the setting of at least one of the rotation speed of the base and the lifting speed of the cylindrical container so that the nozzle injection pattern does not overlap with that of the first round when the base rotates and enters the second round Then, as the base repeats rotating, the position where the cleaning fluid hits gradually shifts, so even if there is a part where the cleaning fluid did not hit on the first round, the whole object to be cleaned The cleaning fluid is sprayed on the surface. Therefore, the cleaning apparatus of the present invention does not require strict adjustment of the position and angle of the cleaning nozzle even if the structure is different for each object to be cleaned, and can perform efficient cleaning with a small number of cleaning nozzles. In addition, since the nozzle injection pattern can be determined by numerical values such as speed (rotation speed of the base, lifting speed of the cylindrical container), it is reproducible with respect to how the cleaning fluid hits the cleaning nozzle, and the skill of the operator Even if it is not worn, it is possible to stably obtain a highly accurate cleaning effect.

Furthermore, the cleaning device of the present invention is configured to move up and down while the cylindrical body or cylindrical container covers the base, so that the cylindrical body or the amount of cleaning liquid ejected from the cleaning nozzle can be reduced. If the setting is such that the gap between the cylindrical container and the base is larger than the amount of the cleaning liquid that flows out, it will be an air cleaning suitable for cleaning the object to be cleaned with a smooth surface.
On the other hand, if the amount of the cleaning liquid ejected from the cleaning nozzle is set to be smaller than the amount of the cleaning liquid flowing out of the gap between the cylindrical body or the cylindrical container and the base, the cleaning liquid gradually becomes cylindrical. Alternatively, it is possible to perform cleaning (immersion) in a liquid suitable for cleaning an object to be cleaned that has accumulated in a cylindrical container and has a complicated internal structure.

  As described above, this cleaning apparatus has an advantage that various types of objects to be cleaned can be efficiently cleaned at a high level and exhibit a certain effect.

  In the cleaning apparatus according to a second aspect of the present invention, at least two cleaning nozzles are disposed at equal intervals in the height direction.

  According to this configuration, since the object to be cleaned is cleaned so that each cleaning nozzle is assigned according to its height, the cylindrical body or the cylinder is compared with the case where the number of cleaning nozzles is one. The amplitude of the vertical reciprocating motion of the container can be reduced, and the cleaning time is shortened.

  As an example, two cleaning nozzles are arranged with a height of 80 mm each, as in the cleaning apparatus of FIG. 5A, and the top and bottom are directed toward a cylindrical object to be cleaned having a height of 150 mm and a diameter of 200 mm. When the cleaning fluid is ejected while moving the cylindrical container up and down with an amplitude W of 85 mm, the position of the cleaning fluid that hits the object to be cleaned is, for example, a nozzle ejection pattern drawn by two lines in the developed view of FIG. become. At this time, the cleaning nozzle 151 is provided at one place at a height of 0 mm at 90 ° and at one place at a height of 80 mm at 270 ° (dotted circles in the figure). The solid line portion of the nozzle ejection pattern indicates the position where the fluid from each cleaning nozzle hits the first round, and the broken line portion shows the position where the fluid hits the second round. In FIG. 5B, the cleaning fluid is moved while the cylindrical container is moved up and down while the rotational speed of the base is 7.5 rpm, the vertical speed of the cylindrical container is 145.9 mm / sec, and the vertical amplitude W is 85 mm. It is a nozzle injection pattern when.

  Further, as an example, as shown in FIG. 1, three cleaning nozzles are arranged with a height of 50 mm each, and when the cleaning fluid is ejected while moving the cylindrical container up and down with an upper and lower amplitude W of 68 mm, 4A to 4C show the position of the cleaning fluid that hits the cleaning object. The three lines in each development view are nozzle ejection patterns.

  At this time, the values of the rotational speed of the base and the lifting speed of the cylindrical container are (rotating speed of the base, lifting speed of the cylindrical container) = ((a): 4.5 rpm, 145.9 mm / sec), ((b) 7.5 rpm, 145.9 mm / sec), ((c): 4.5 rpm, 38.9 mm / sec). The cleaning nozzle is provided at two locations of 0 mm and 100 mm in height at 90 ° and one location at 50 mm in height at 270 ° (dotted circles in the figure). The solid line portion of the nozzle ejection pattern indicates the position where the fluid from each cleaning nozzle hits the first round, and the broken line portion shows the position where the fluid hits the second round.

  Thus, if the number of cleaning nozzles is increased to 4, 5, 6, 7, or 8, the amount of the cleaning nozzle for cleaning the object to be cleaned decreases, and the cylinder or The amplitude of the vertical reciprocation of the cylindrical container can be reduced, and the cleaning time can be shortened.

  However, as the number of cleaning nozzles increases, the cleaning level can be increased, but the weight and cost of the cleaning device increase. Therefore, in order to reduce the weight and cost of the cleaning apparatus while maintaining a constant cleaning level, the number of cleaning nozzles is preferably about 2 to 24, more preferably 2 to 12.

  In the cleaning apparatus according to a third aspect, there are at least two cleaning nozzles, and the cleaning nozzles are arranged at equal intervals in the circumferential direction.

  Here, “equally spaced in the circumferential direction” means, for example, that two cleaning nozzles are arranged at positions facing each other by 180 degrees, four cleaning nozzles are arranged every 90 degrees, or six cleaning nozzles Is arranged every 60 degrees. Alternatively, a plurality of cleaning nozzles may be arranged at equal intervals in the circumferential direction, for example, two cleaning nozzles are installed at every 180 degrees.

  According to this configuration, the cleaning liquid can be efficiently ejected onto the object to be cleaned, the fine setting of the cleaning nozzle can be performed, and various objects to be cleaned can be handled.

  In the cleaning apparatus according to a fourth aspect, a water supply port capable of supplying a liquid toward the inside thereof is provided at an upper portion of the cylindrical body or the cylindrical container.

  Here, as the “liquid”, the cleaning liquid may be used, or a dipping liquid (for example, water) may be used separately.

  According to this configuration, in addition to the cleaning liquid sprayed from the cleaning nozzle, liquid (cleaning liquid or immersion liquid) can be supplied from the water supply port into the cylinder or the cylindrical container. In addition, the object to be cleaned can be quickly immersed in the liquid, so that efficient cleaning in the liquid can be performed. Therefore, the operator can easily switch between liquid cleaning and air cleaning by appropriately setting the presence or absence of liquid water supply from the water supply port.

  In the cleaning apparatus according to claim 5, an elastic member is provided on a peripheral edge portion of the base.

  According to this configuration, even if the gap between the base and the cylinder or the cylindrical container is wide, the gap can be reduced by the elastic member such as a rubber seal, and the outflow of the cleaning liquid from the gap can be reduced. Accordingly, the object to be cleaned can be immersed in the liquid more quickly, and cleaning in the liquid can be performed efficiently.

  In addition, it is good also as a structure which contact | abuts the elastic member of a base outer edge part, and a cylinder or a cylindrical container inner wall, and in that case, a rubber seal outer edge and a cylinder or by making a notch in the outer edge of a rubber seal at a fixed space | interval Damage to the rubber seal due to friction with the inner wall of the cylindrical container can be mitigated.

  In the cleaning apparatus according to a sixth aspect, an upper drainage port is provided at an upper side surface of the cylindrical body or the cylindrical container.

  According to this configuration, when cleaning in liquid, light residual foreign matter floating on the surface in the liquid can be removed together with the cleaning liquid overflowing from the upper drainage port. Conversely, heavy residual foreign matter that sinks to the bottom can flow out together with the cleaning liquid from the gap between the base and the cylinder. As a result, the replacement rate of the cleaning liquid in the container is improved, re-adhesion of residual foreign matters to the object to be cleaned can be prevented, and effective cleaning can be performed.

  In the cleaning apparatus according to claim 7, a drainage hole is provided in the base.

  According to this configuration, the heavy residual foreign matter that sinks to the bottom can be discharged together with the cleaning liquid from the drain hole in addition to the gap between the base and the cylinder, and the replacement rate of the cleaning liquid in the container is further improved. Thus, the reattachment of the remaining foreign matter to the object to be cleaned can be prevented more efficiently.

  In the cleaning apparatus according to claim 8, the cleaning nozzle is a two-fluid nozzle.

  According to this configuration, it is possible to eject different fluids concentrically from the cleaning nozzle, and it is possible to eject the cleaning liquid from the central portion of the cleaning nozzle and air from the periphery thereof. As a result, particularly in liquid cleaning, compared with the case where only the cleaning liquid is ejected from the cleaning nozzle, the fluid reaches the interior of the object to be cleaned more securely, for example, to the back of the hole, so that the cleaning effect is enhanced.

  The cleaning fluid ejected from the two-fluid nozzle is preferably a multiphase fluid composed of cleaning liquid and gas ejected with straightness, and the cleaning liquid and gas constituting the multiphase fluid. If the cleaning liquid and the gas are mixed immediately after the injection, there is no problem that the speed reduction of the multiphase fluid is remarkably reduced, and the multiphase fluid is covered. It can be efficiently fed to the washed product. Thereby, especially in the submerged cleaning, since it is possible to improve the jetting force of the cleaning fluid to the object to be cleaned, the cleaning efficiency and the cleaning ability can be improved.

  As described above, according to the cleaning device of the present invention, even a cleaning object having a complicated internal structure such as a circuit-shaped hole can be efficiently and efficiently adjusted without strict adjustment of the position and angle of the cleaning nozzle. It can be cleaned effectively. In addition, since the number of cleaning nozzles can be reduced, a compact configuration can be achieved, and air cleaning and liquid cleaning can be appropriately performed with a single cleaning apparatus, leading to reduction in equipment cost and operation cost.

The cup 4 is arranged with the opening facing downward so as to cover the base 3 and the object to be cleaned 10 from above. Yes. A disk-shaped rubber seal 34 for closing a gap between the peripheral edge of the base 3 and the inner peripheral surface of the cup 4 is provided on the base 3. The outer edge of the rubber seal 34 is cut along the diameter at approximately 45 ° intervals.

  Three cleaning nozzles 5 (51, 52, 53) are arranged at equal intervals D in the height direction, and are fixed to penetrate the side surface of the cup 4. Two of the cleaning nozzles 51 and 53 are fixed to the same position in the circumferential direction of the cup 4 with an interval of 100 mm, and the remaining one cleaning nozzle 52 is positioned so as to oppose them in the circumferential direction ( It is fixed at an intermediate height (positions spaced by 180 degrees) (see FIGS. 2 and 3). The arrangement of the cleaning nozzles 5 may be other than that. For example, three cleaning nozzles 5 may be installed at intervals of 120 degrees in the circumferential direction. The number may be four and 90 degrees apart from each other in the circumferential direction.

  The cleaning nozzle 5 is a two-fluid nozzle. This may be a known one, for example, as shown in FIG. 2, provided with an injection port 5a for the cleaning liquid at the center and an injection port 5b for injecting air around it. In addition, when not performing in-liquid washing | cleaning, you may use a common 1 fluid nozzle.

  An air cylinder 6 is provided vertically in the center of the upper surface portion 21 of the main body 2. The air cylinder 6 incorporates a rod 62 that can be raised and lowered by air pressure sent from an air supply pump (not shown). The rod 62 penetrates the upper surface portion 21 of the main body 2 and extends downward, and its tip is fixed to the center of the upper surface portion 41 of the cup 4. Accordingly, the cup 4 is suspended from the rod 62 in the main body 2 and can be moved up and down together with the rod 62 by air pressure. The three cleaning nozzles 5 fixed to the cup 4 also perform the same up-and-down movement.

  The air cylinder 6 has a stroke of a maximum of 300 mm, and the cup 4 descends to a position where the lower end of the cup 4 is lowered by 60 mm from the bottom of the base 3. If the cup 4 is pulled up to the top, the height of the main body 2 is set so that the turntable 31 can be pulled out of the main body 2 and stored in the main body 2 while the object to be cleaned 10 is placed on the base 3. ing. The air cylinder 6 may be an electric cylinder or a robot cylinder.

  The upper surface portion 41 of the cup 4 is provided with a large flow rate water supply port 42 for injecting a cleaning liquid and immersing the object 10 to be cleaned. In addition, an upper drainage port 43 is provided at the upper part of the side surface of the cup 4, and the cleaning liquid containing the remaining heavy foreign matter overflows from the cup 4. Further, a waterproof pan 22 and a lower drainage port 23 are provided below the turntable 31, and the cleaning liquid overflowed from the upper drainage port 43 and heavy residual foreign matter discharged from the gap between the cup 4 and the base 3 are included. The cleaning liquid is discharged from the lower drainage port 23.

  The supply of the cleaning liquid to the cleaning nozzle 5 and the water supply port 42 is performed by the cleaning liquid pump connected to the outside of the main body 2 as described above. Further, the cleaning liquid containing residual foreign matter discharged from the lower drainage port 23 is sent to a cleaning liquid pump and circulated after the residual foreign matter is removed by a filter. In addition, when supplying the water for immersion separately from the water supply port instead of the cleaning liquid, a dedicated pump for the immersion water may be separately provided in addition to the cleaning liquid pump.

  The positional relationship between the cup 4 and the object to be cleaned 10 when the cylindrical object 10 having a diameter of 200 mm and a height of 150 mm is cleaned with the cleaning device 1 configured as described above is shown in FIG. Shown in (b). Here, the amplitude W of the elevating motion of the cup 4 is set to 68 mm. At this time, the position where the fluid (cleaning liquid and air) from each cleaning nozzle 51, 52, 53 hits the surface of the object to be cleaned 10 is determined by the rotational speed of the base 3 and the ascending / descending speed of the cup 4. 4A to 4C show the respective nozzle ejection patterns in the combinations of the rotation speed and the elevation speed shown in the table below.

Rotational speed of the base Lifting speed of the cylindrical container (a) 4.5rpm 145.9mm / sec
(B) 7.5 rpm 145.9 mm / sec
(C) 4.5 rpm 38.9 mm / sec

  The horizontal axis in FIG. 4 represents the position (angle) developed in the circumferential direction on the surface of the article 10 to be cleaned, and the vertical axis represents the position in the height direction. Broken circles in the figure are the projections of the positions of the respective cleaning nozzles 51, 52, 53 fixed to the side surface of the cup 4 and the spray diameters of the nozzles on the surface of the object to be cleaned 10. The two cleaning nozzles 51 and 53 are at the same position (90 °) in the circumferential direction, and the heights with respect to the object to be cleaned 10 are 100 mm and 0 mm, respectively. Another cleaning nozzle 52 is in a position (270 °) opposite to them, and the same height is 50 mm. Note that the upper, middle, and lower broken lines in FIG. 4 correspond to the cleaning nozzles 51, 52, and 53, respectively, and the solid line represents the first turn and the long broken line represents the second turn.

  It can be seen that the upper, middle, and lower three broken lines in each figure of FIG. 4 overlap each other and shift from the position of the previous circumference when entering the second round. Thus, the entire surface of the object to be cleaned 10 can be cleaned by repeating the rotation after adjusting the rotation speed of the base 3 and the elevation speed of the cup 4.

  Using the cleaning apparatus 1 described above, the water pump with the remaining foreign matter adhered as the object to be cleaned 10 was cleaned, and the cleaning accuracy was tested. Hereinafter, the cleaning conditions and results will be described.
