Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic cleaning machine and an ultrasonic cleaning system, and more particularly to an ultrasonic cleaning machine and an ultrasonic cleaning system for cleaning while transferring an object to be cleaned.

[0002]

2. Description of the Related Art There are various types of ultrasonic cleaners conventionally. For example, as shown in (a) Japanese Patent Application Laid-Open No. 8-299926, (a) a method in which objects to be washed are stored in a basket randomly or in a stacked state and water-based ultrasonic cleaning or water-based jet cleaning is performed. Then, the objects to be cleaned are arranged in a basket (barrel), and then ultrasonically cleaned while moving them up and down while moving in water. Further, (c) a cylindrical barrel is laid on one side and There is a method in which aqueous ultrasonic cleaning or aqueous jet cleaning is performed while moving to the other side.

[0003] Among them, in the above (c), for example, a rotary basket (barrel) containing objects to be cleaned is placed sideways, and this is placed in a water tank (washing liquid tank) and rotated and transferred, and the inner wall is moved. The shower cleaning is performed while moving the object to be cleaned by the spiral feed mechanism provided in the apparatus.

[0004]

However, in each of the above-mentioned conventional examples, the method of carrying out aqueous ultrasonic cleaning or aqueous jet cleaning by storing the objects to be cleaned (a) randomly or in a stacked state in a basket. However, since the cleaning is performed at a fixed position, there is an inconvenience that cleaning unevenness easily occurs.

The method of (b), in which the objects to be cleaned are arranged in a basket and then moved up and down while moving in water to perform ultrasonic cleaning while moving up and down, is disclosed in, for example, JP-A-8-29992.
As disclosed in Japanese Patent Application Publication No. 6-205, a large water tank is used because the object to be cleaned is stored in a basket (barrel), then submerged in a water tank (cleaning liquid), and then the entire barrel is rotated. (A cleaning liquid tank) is required, which causes an inconvenience of increasing the size of the entire apparatus.

Further, in these two methods, when the object to be cleaned in the basket (barrel) is finished, all the objects to be cleaned are taken out, and then the next object to be cleaned is transferred to the basket (barrel) again. ) Requires a step of storing the cleaning solution, and the cleaning operation is intermittent, which results in inconvenience of poor workability.

[0007] A method in which a water-based ultrasonic cleaning or a water-based jet cleaning is performed while moving the cylindrical bullet from the one side to the other side while developing the cylindrical bullet in the above (c) as an improved type of the above-mentioned two systems, , The cleaning liquid is moved from one side to the other together with the object to be cleaned. For this reason, the dirt removed from the object to be cleaned also moves in the same direction together with the object to be cleaned, which often causes the inconvenience that the dirt adheres to the object to be cleaned again, thereby deteriorating the cleaning quality. Inconvenience had occurred.

[0008]

SUMMARY OF THE INVENTION The object of the present invention is to improve the disadvantages of the prior art, to enable continuous operation and to improve the cleaning quality of the cleaning object, and to provide good durability and maintainability, and to provide a long time. It is an object of the present invention to provide a highly reliable ultrasonic cleaner and an ultrasonic cleaning system that can maintain good cleaning quality even when used.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, the object to be cleaned is washed from one side, which is the side for carrying the object to be cleaned, while rotating the object to be cleaned irregularly. A rotary transfer means for transferring the object to be cleaned obliquely upward toward the other side, an ultrasonic cleaning means for ultrasonically cleaning the object to be cleaned through the cleaning liquid during the transfer of the object to be cleaned, The cleaning object is provided on the other side, which is the object delivery side, and is pushed out of the water surface in the process of being transferred obliquely upward from the cleaning liquid, and thereafter, the cleaning liquid is sprayed on the cleaning object to spray the cleaning object on the water system. A water-based jet cleaning mechanism for jet cleaning. In addition, a configuration is adopted in which a cleaning liquid discharge unit that discharges the cleaning liquid of the above-described ultrasonic cleaning means in an overflow state is disposed on the side of the object to be cleaned.

For this reason, in the invention according to claim 1,
First, the object to be cleaned is rotated in the barrel by rotating, for example, an obliquely disposed cylindrical barrel. By equipping the inner wall of the barrel with, for example, a spiral plate mechanism, the object to be cleaned is transferred from the lower side (one side) to the upper side (the other side) while rotating irregularly by the spiral plate mechanism. In this case, the place where the object to be cleaned has been carried in is submerged in the cleaning liquid in the ultrasonic cleaning tank of the ultrasonic cleaning means. Washed.

When the object to be cleaned is pushed out of the water surface in the process of being transferred obliquely upward, the object to be cleaned is subjected to water jet cleaning by a water jet cleaning mechanism. These series of steps of the ultrasonic cleaning and the water-based jet cleaning are performed in a process in which the object to be cleaned is transferred from obliquely downward to obliquely upward.

In particular, since the water jet cleaning is performed continuously immediately after the ultrasonic cleaning, the cleaning power can be dramatically increased. Further, since these series of cleaning steps are continuously performed, it is possible to significantly improve the efficiency of the cleaning operation of the object to be cleaned.
In addition, during the operation of the series of cleaning steps, the cleaning liquid in the ultrasonic cleaning tank described above is drained at the same time in the form of overflow in the direction opposite to the transfer direction of the object to be cleaned.

[0013] For this reason, dirt particles, removed oil particles, and the like located in the upper layer region of the cleaning liquid in the ultrasonic cleaning tank can be continuously removed from the direction opposite to the transfer direction of the object to be cleaned and removed. The degree to which the oil particles and the like adhere to the object to be cleaned is greatly reduced.

In each of the second to seventh aspects of the present invention, a cylindrical barrel having a through-hole for liquid circulation formed substantially over the entire periphery thereof, and a rotational center axis of the barrel slightly rising with respect to a horizontal plane. It comprises a rotation holding mechanism which is set obliquely and rotatably holds the barrel, and a barrel drive mechanism which drives the barrel to rotate.

The falling side of the barrel is the loading side of the article to be cleaned, and the upper side is open and the lower surface area on the falling side of the barrel is disposed so as to be partially submerged, facing the lower surface side of the entire barrel. Equipped with an ultrasonic cleaning tank. Further, the ultrasonic cleaning tank is equipped with an ultrasonic oscillator for ultrasonic cleaning.

Further, the rising side of the barrel is set as the sending side of the object to be cleaned, and a liquid jet nozzle for water-jet cleaning the object to be cleaned in the barrel is provided at an opening on the rising side of the barrel.

The inner wall of the barrel is provided with a spiral plate mechanism for transferring the object to be cleaned from the falling side to the rising side of the barrel together with the rotating operation of the barrel, and the inside of the ultrasonic cleaning tank. The cleaning liquid discharging section for discharging the cleaning liquid in an overflow state is provided on the falling side of the barrel as the basic configuration.

For this reason, in each of the inventions according to claims 2 to 7, in addition to functioning in the same manner as the invention described in claim 1, a through-hole for liquid circulation is formed in the barrel over the entire periphery. Therefore, the flow of the cleaning liquid at a location submerged in the ultrasonic cleaning tank is freely performed between the inside and the outside of the barrel, and therefore, the rotation operation of the barrel and the exchange of the cleaning liquid are performed smoothly. In this regard, the cleaning effect on the object to be cleaned can be significantly improved.

At the same time, when the cleaning liquid discharge section is operated, the cleaning liquid is discharged in an overflow state. However, suspended matter floating in the cleaning liquid in the barrel is also directly sucked into the cleaning liquid discharge section through the liquid flow through hole. You. Therefore, the suspended matter of the cleaning liquid in the barrel is discharged more quickly and smoothly. In this respect, the cleaning effect can be improved.

Here, in the above-mentioned cylindrical barrel, a part of the opening on the falling side of the barrel is disposed in the liquid in the ultrasonic cleaning tank, and the opening on the rising side of the barrel is superposed. It is preferable to arrange on the ultrasonic cleaning tank so as to be located above the liquid level of the ultrasonic cleaning tank.

With this arrangement, the cleaning liquid is not discharged in the same direction together with the object to be cleaned, and the separated cleaning object can be reliably separated from the cleaning liquid, and the scattering of the cleaning liquid can be prevented. It is possible to reliably prevent dirt from being transferred to a subsequent process.

Further, a predetermined projection may be provided on the entire surface of the spiral plate mechanism (the surface on the side where the object to be cleaned is pushed up). In this case, the protrusion may be an annular protrusion. The protrusion may be a wire-like protrusion formed by continuously applying wires, or a net-like protrusion formed by continuously applying wires.

In this way, even if the object to be cleaned is a flat one such as a washer, it is possible to eliminate the inconvenience that the object to be cleaned adheres to the surface of the spiral plate mechanism and the transfer of the object to be cleaned is hindered. In this respect, there is an advantage that the cleaning transfer of the object to be cleaned can be performed smoothly.

According to an eighth aspect of the present invention, there is provided the ultrasonic cleaner according to the second, third, fourth, fifth, sixth, or seventh aspect, wherein a cover is provided around the barrel and entirely around the barrel. An opening is provided in each of the lower regions on the loading side and the delivery side of the article to be cleaned into the barrel described above.

Therefore, according to the invention of claim 8,
In addition to functioning equivalently to the above-described claims 2, 3, 4, 5, 6 or 7, it is also possible to reliably prevent the cleaning liquid from scattering around, and to use the cleaning liquid repeatedly. There is an advantage that consumption can be reduced.

According to a ninth aspect of the present invention, in the above-described ultrasonic cleaning machine according to the second, third, fourth, fifth, sixth, or seventh aspect, the cleaning is performed by spray cleaning the opening in the barrel on the side where the cleaning object is delivered. An air nozzle unit for injecting air for draining the cleaned object is provided.

Therefore, in the invention according to claim 9,
In addition to functioning equivalently to the invention described in 2, 3, 4, 5, 6, 7 or 8 described above, a forced liquid draining process by jetting air is set immediately after water-based jet cleaning, so that barrels are used for large water droplets. Can be blown into the inside and small water droplets can be made to be in a state close to dry, so that the water adhering to the object to be cleaned is efficiently and continuously drained only by passing through a relatively small space area. In this respect, there is an advantage that the cleaning liquid is not carried over to the next step.

According to the tenth aspect of the present invention, two sets of ultrasonic cleaners which are substantially identical to each other are arranged along the moving direction of the object to be cleaned. And, each ultrasonic cleaning machine, a rotating transfer means for transferring the cleaning liquid obliquely upward from one side to the other side while rotating the object to be cleaned irregularly, and during the transfer of the object to be cleaned. Ultrasonic cleaning means for ultrasonically cleaning the object to be cleaned via the cleaning liquid, and spraying the cleaning liquid onto the object to be cleaned after the object to be cleaned is pushed out from the water surface on the other side of the cleaning liquid; A water-based jet cleaning mechanism for water-based jet cleaning, and a cleaning liquid discharge section for discharging the cleaning liquid of the above-described ultrasonic cleaning means in an overflow state to the side to be cleaned.

In the two sets of ultrasonic cleaners, the ultrasonic cleaner located upstream in the moving direction of the object to be cleaned is referred to as an ultrasonic cleaning machine for cleaning, and the ultrasonic cleaner for cleaning is disposed downstream in the moving direction of the object to be cleaned. The ultrasonic cleaner located on the side is designated as an ultrasonic cleaner for rinsing. Further, between the opening on the downstream side of the barrel of the ultrasonic cleaning machine for cleaning and the opening on the upstream side of the barrel of the ultrasonic cleaning machine for rinsing described above, a cleaning object moving guide mechanism is provided. It has a configuration.

For this reason, the invention according to claim 10 has the same function as that of the invention described in claim 1, and furthermore, the cleaning side and the rinsing side are divided so as to be able to cooperate. The cleaning effect can be remarkably improved without significantly increasing the working time, and the durability and maintainability are good, and good cleaning quality can be maintained even when used for a long time.

For this reason, the thing to be washed which is transported upward in the barrel 2 while being slightly deviated from the central axis can be reliably captured.

Further, an air blow mechanism 35 is provided on the other side of the barrel 2 which is the above-mentioned sending side of the object to be cleaned. The air blow mechanism 35 is for the object to be cleaned, which has been cleaned by the water-based jet cleaning mechanism 31 described above,
This is for draining the liquid by blowing clean and dry air to all of the objects to be cleaned. In FIG. 1, reference numeral 38 denotes a compressor.

The air blow mechanism 35 is provided at a predetermined position in the barrel 2 and has one or more air nozzles 36a for injecting liquid draining air downwardly on the inner surface of the barrel 2. And the air nozzle portion 3 that holds the air nozzle portion 36 and

The barrel 2 is set to be inclined at a predetermined angle toward the downstream side in the rotating direction of the barrel 2 (for example, in a state of rising by β ₁ = 30 ° with respect to a horizontal line at the center of the air nozzle portion 36). The air jet direction is set to be inclined toward the inside by a predetermined angle (for example, γ ₁ = 20 °) with respect to the opening surface on the sending side of the object to be cleaned.

As shown in FIG. 14, for example, γ is rotated clockwise with respect to the opening surface of the barrel 2 on the side of the object to be cleaned.
₂ = set to a state of rotation of 20 °, thereby equipping the spiral plate mechanism 5 so as to be opposed to the inclination angle (spiral angle) of the spiral plate mechanism 5, thereby suppressing the influence of air reversal from the spiral plate mechanism 5. doing.

For this reason, in the process of transporting the ultrasonically cleaned object to be cleaned upward, the whole of the object to be cleaned is easily captured, and air for draining the curtain is sprayed over the entire object to be cleaned. Thus, there is an advantage that the amount of the cleaning liquid that is quickly and uniformly drained over the entirety and brought to the next step can be reduced.

Further, the position of the center of the air nozzle portion 36 is slightly shifted toward the rising side of the side wall when the barrel 2 rotates, based on the above-described vertical plane including the center axis of the barrel 2. (A position approximately the same as the liquid jet nozzle portion 36). For this reason, the whole to-be-cleaned thing is in a state where it is easier to catch.

A cleaning liquid storage layer 40 is provided below the ultrasonic cleaning tank 7 via a pipe (see FIGS. 1 and 2). The cleaning liquid storage layer 40 includes a first recovery pipe 41 for recovering the cleaning liquid in the ultrasonic cleaning tank 7 as needed, and a second recovery pipe for recovering the cleaning liquid overflowing in the ultrasonic cleaning tank 7. And a third recovery pipe 43 for recovering the cleaning liquid that has flowed into the outer region (the space on the right side in FIG. 1) partitioned by the partition plate 7A of the ultrasonic cleaning tank 7.

Further, the cleaning liquid storage layer 40 has a cleaning liquid supply pipe 44 for supplying a cleaning liquid from the outside, a drain pipe 47 for draining the cleaning liquid in the cleaning liquid storage layer 40 to the outside as necessary, and the above-described drain pipe 47.

The above-mentioned cleaning liquid storage layer 40 is provided with a partition plate 40A whose underwater portion is opened, and floating substances (dirt) in the cleaning liquid overflowing and collected in the ultrasonic cleaning tank 7 are disposed on one side. They can be collected intensively. The collected suspended matter (dirt) is removed by an oil skimmer or the like. Further, the cleaning liquid storage layer 40 is equipped with a heater (not shown), and is driven and controlled by the above-described control circuit unit as needed, thereby maintaining a high cleaning ability.

Next, the operation of the first embodiment will be described.

First, an object to be cleaned such as a bolt, a nut or a washer is carried into the cylindrical barrel 2 by the belt conveyor 101. In this case, the belt conveyor 10
1 is that the end of the cleaning object is disposed on the carry-in guide 100A supported by the case main body 100 (see FIGS. 1 and 2), so that the object to be cleaned is brought into the cover 30 by natural fall through the carry-in guide 100A. It is carried into one side (the left end in FIGS. 1 and 2) in the barrel 2 from the side opening 30A.

The cylindrical barrel 2 constitutes a main part of the rotary transfer means 1, and rotates the carried object to be cleaned, and causes the spiral plate mechanism 5 provided therein to act to rotate the cleaning liquid from one side to the other side. Transfer toward. In this case, the location where the object to be cleaned has been carried in is submerged in the cleaning liquid in the ultrasonic cleaning tank 7, and the barrel 2 is provided with a through-hole 2a for liquid circulation on the entire surface thereof. The place where the object to be cleaned is carried in is located in the cleaning liquid in the ultrasonic cleaning tank 7.

Since the barrel 2 rotates in such a state, the object to be cleaned is transported in the rotation direction with the rotation of the barrel 2, and is shifted as a whole in the rotation direction, and with the rotation of the side wall of the barrel 2 rising. It falls under its own weight and rotates irregularly. At the same time, the spiral plate mechanism 5 gradually moves to the right (ie, obliquely above the barrel 2) in FIGS.
Is transported.

In the course of this transfer, the object to be cleaned is ultrasonically cleaned by the ultrasonic cleaning means 6. At the same time, since the object to be cleaned is transferred obliquely through the cleaning liquid in the ultrasonic cleaning means 6, the distance between the object and the ultrasonic oscillator 8 gradually changes. The cleaning residue of the pattern is eliminated, and the entire periphery of the object to be cleaned is ultrasonically and uniformly cleaned.

Then, when the object to be cleaned is pushed out from the water surface on the other side in the cleaning liquid, the object to be cleaned is subjected to water jet cleaning by the water jet cleaning mechanism 31. Subsequently, after the aqueous jet cleaning, the air blow mechanism 35 is used.
As a result, water droplets on the entire object to be cleaned are removed. The used cleaning liquid in this case also moves in the barrel 2 to the falling side in the opposite direction to the transfer direction of the object to be cleaned and is collected in the ultrasonic cleaning tank 7.

Therefore, also at this point, the dirt discharged by the cleaning and the object to be cleaned can be smoothly separated. These series of steps of the ultrasonic cleaning, the water-based jet cleaning, and the liquid removal are performed in a process in which the object to be cleaned is transferred by the barrel 2 from obliquely downward to obliquely upward.

The object to be cleaned after the liquid draining step in the final stage is pushed out of the barrel 2 to the outside through the above-mentioned delivery side opening 30B of the cover by the action of the spiral plate mechanism 5 in the barrel 2. However, since the delivery guide 100B is provided below the fall, the object to be cleaned is guided on the belt conveyor 102 and carried out through the delivery side opening 30B.

Further, since the series of cleaning and draining steps are performed continuously, the efficiency of the cleaning operation of the object to be cleaned is significantly improved. In addition, during the operation of the series of cleaning and draining steps, the ultrasonic cleaning tank 7 described above is simultaneously operated.
The cleaning liquid in the inside is drained in the form of overflow in the direction opposite to the transfer direction of the object to be cleaned.

Therefore, dirt particles, removed oil particles and the like located in the upper layer region of the cleaning liquid in the ultrasonic cleaning tank 7 can be continuously taken out from the direction opposite to the transport direction of the object to be cleaned. There is an advantage that the degree to which the oil particles and the like adhere to the object to be cleaned is greatly reduced.

[0107]

The present invention is constructed and functions as described above. According to the present invention, according to the first aspect of the present invention, the process from the loading of the object to be cleaned to the delivery to the outside through the cleaning process is performed continuously. It can be performed continuously, and the ultrasonic cleaning and the subsequent water-based jet cleaning can be continuously performed. For this reason, even if a normal water-based detergent is used, it is inferior to a conventional chlorine-based petroleum-based solvent. As a result, a series of steps of ultrasonic cleaning and water-based jet cleaning are performed in a process in which an object to be cleaned is transferred from obliquely downward to obliquely upward. Can be planned.

Further, during the operation of the series of cleaning and draining steps, the cleaning liquid in the ultrasonic cleaning tank described above is simultaneously discharged.
Since the drainage is set to overflow in the direction opposite to the transfer direction of the object to be cleaned, dirt particles and removed oil particles located in the upper layer area of the cleaning liquid in the ultrasonic cleaning tank are removed from the object to be cleaned. It can be taken out continuously from the direction opposite to the transfer direction, which greatly reduces the degree of contamination of the object to be cleaned after cleaning. Enables operation and improves the cleaning quality of the cleaning object, and has good durability and maintainability, and maintains good cleaning quality even when used for a long time, even when using a normal water-based detergent. It is possible to provide a highly reliable ultrasonic cleaner capable of performing the above.

In each of the second to seventh aspects of the present invention, in addition to the same operation and effect as the above-described first aspect of the present invention, a through-hole for liquid circulation is formed in the barrel over the entire periphery. Therefore, the flow of the cleaning liquid at a location submerged in the ultrasonic cleaning tank is freely performed between the inside and the outside of the barrel, and therefore, the rotation operation of the barrel and the exchange of the cleaning liquid are performed smoothly. The cleaning liquid can be remarkably improved, and the cleaning liquid is discharged in an overflow state when the cleaning liquid discharge section is activated, but the floating substances floating in the cleaning liquid in the barrel also penetrate through the liquid flow. Since the cleaning liquid is directly sucked into the cleaning liquid discharge section through the hole, the suspended matter of the cleaning liquid in the barrel can be discharged more quickly and smoothly, and the cleaning effect can be further improved.

Further, when the opening on the rising side of the barrel is disposed on the ultrasonic cleaning tank so as to be located above the liquid surface of the ultrasonic cleaning tank, the cleaning liquid is discharged in the same direction together with the object to be cleaned. The cleaning liquid can be reliably separated from the object to be cleaned and the cleaning liquid, the scattering of the cleaning liquid can be prevented, and the dirt can be reliably prevented from being transferred to a subsequent process.

If a predetermined projection is provided on the entire surface of the spiral plate mechanism (the surface on the push-up side with respect to the object to be cleaned), even if the object to be cleaned is a flat one such as a washer, the spiral is formed. Inconvenience that the transfer of the object to be cleaned is hindered by adhering to the surface of the plate mechanism can be eliminated, and in this regard, the cleaning is smoothly and continuously continued efficiently regardless of the shape of the object to be cleaned. can do.

According to the eighth aspect of the present invention, the same effects as those of the second, third, fourth, fifth, sixth or seventh aspect of the present invention are provided, and further, the washing liquid is surely prevented from scattering around. It can be prevented, and when the cleaning liquid is repeatedly used, its consumption can be reduced.

According to the ninth aspect of the present invention, in addition to having the same operational effects as those of the second, third, fourth, fifth, sixth, seventh, and eighth aspects, air is blown immediately after the aqueous jet cleaning. Since the process of forced drainage by spraying is set, large water droplets can be blown into the barrel and small water droplets can be forcibly drained to a state close to drying, so that a relatively small space area is set. By simply passing through, the object to be cleaned can be efficiently and continuously drained, and the steps of washing and draining can be performed smoothly in a short time and with a small space space. Can be significantly improved.

According to the tenth aspect of the present invention, in addition to having the same function as that of the first aspect of the present invention, the cleaning side and the rinsing side are divided so as to be able to cooperate with each other. The cleaning effect can be significantly improved without significantly increasing the time, and the durability and maintainability are good, and good cleaning quality can be maintained even when used for a long time.
