However, the above-described conventional sonic cleaning mechanism has the following problems. (1) Water is hardly generated, and particularly when washing a textile such as clothing, when a solid detergent or a powder detergent is used, the detergent is less likely to be diffused throughout the object to be washed. (2) The mechanical configuration is complicated and maintenance is poor. (3) Noise measures are required. (4) Since it is a batch processing method in which batch washing is performed, it is not suitable for performing a cleaning process corresponding to each object to be cleaned. (5) Washing is possible but not suitable for rinsing since a water flow is unlikely to occur.

[0007] The push-washing and cleaning mechanism has the following problems. (1) Water supply and drainage are required for each washing and rinsing, which requires a large amount of washing water and a large amount of drainage. In particular, when the number of objects to be cleaned is small, the amount of water supply and drainage with respect to the amount of the object to be cleaned increases. (2) Since the BOD and COD of wastewater are high and the amount of wastewater is large,
Requires a large water treatment device. (3) Since it is a batch processing system in which batch washing is performed, it is not suitable for performing a cleaning process in accordance with the properties of individual objects to be cleaned.

Further, the brush cleaning mechanism and the spray cleaning mechanism have the following problems. (1) Water supply and drainage are required for each washing and rinsing, which requires a large amount of washing water and a large amount of drainage.

Further, the cleaning apparatus of the present invention is capable of performing continuous cleaning processing and is excellent in workability when cleaning a large amount of objects to be cleaned.
An object of the present invention is to provide a cleaning apparatus which requires a small amount of water supply and drainage for cleaning, enables continuous processing of cleaning and rinsing, and is excellent in maintainability.

[0011]

In order to solve the above-mentioned problems, a cleaning mechanism according to the present invention comprises a cleaning tank, a buffer chamber disposed in the cleaning tank or at the bottom of the cleaning tank and filled with gas, and a buffer chamber. A diaphragm made of an elastic plate disposed on the upper surface of the buffer chamber and separating the buffer chamber and the washing tank; a vibrating body disposed vertically above the vibrating plate in the washing tank; And an object-to-be-cleaned holding means for holding the object to be cleaned between the vibrator and the vibrating plate in the cleaning tank so that the cleaning liquid can pass therethrough.

[0013]

In order to achieve this object, a cleaning mechanism according to a first aspect of the present invention comprises a cleaning tank and a buffer chamber disposed in or at the bottom of the cleaning tank and filled with gas. When,
A vibrating plate disposed on an upper surface of the buffer chamber and formed of an elastic plate for separating the buffer chamber and the cleaning tank; a vibrating body disposed vertically above the vibrating plate in the cleaning tank; A vibrating means for vertically vibrating the liquid; and a cleaning object holding means for holding the cleaning object between the vibrating body and the vibration plate in the cleaning tank through which the cleaning liquid can pass. With this configuration, the following operation is obtained. (1) The cleaning liquid is stored in the cleaning tank until at least the bottom of the vibrator is submerged. The object to be cleaned is held between the vibrating body and the diaphragm in the cleaning tank while being held by the object-to-be-cleaned holding means. In this state, the vibrator vibrates in the vertical direction, and vibrates the cleaning liquid filled between the vibrator and the diaphragm. (2) When the object to be cleaned has high water permeability, when the vibrating body moves downward, the cleaning liquid below the vibrating body passes through the object to be cleaned held by the object to be cleaned holding means from top to bottom. Move to the upper surface of the diaphragm below the means for holding the object to be cleaned. At this time, the diaphragm bends to the inside of the buffer chamber because the pressure of the cleaning liquid on the upper surface increases. Thus, the water flow of the cleaning liquid flowing out from the lower surface of the vibrating body to the periphery thereof when the vibrating body moves downward is suppressed, and the amount of water flowing directly downward and directly passing through the object to be cleaned is increased. Conversely, when the vibrating body moves upward, the cleaning liquid below the vibrating body passes through the object to be cleaned held by the object-to-be-cleaned holding means from below to above, and passes through the object-to-be-cleaned holding means. Move upward. At this time, the diaphragm bends toward the vibrator because the pressure of the cleaning liquid on the upper surface decreases. Therefore, a water flow of the cleaning liquid that passes through the object to be cleaned held by the object to be cleaned holding means and flows repeatedly in the vertical direction is efficiently formed, and the object to be cleaned is efficiently cleaned by the water flow. (3) Since the object to be cleaned is exposed to the water flow of the cleaning liquid, the updated cleaning liquid is always constantly supplied to the surface of the object to be cleaned, so that the dirt is removed by the cleaning action of the cleaning liquid.
The water flow physically removes dirt. (4) When the object to be cleaned is made of a material having poor water permeability, the vibrating body vertically vibrates due to the vertical vibration of the vibrating body, and the vibrating plate deforms accordingly. However, since the object to be cleaned is exposed to the water flow moving at a high frequency in the vertical direction without causing an excessive power load on the vibration means, a high cleaning effect can be exhibited.

[0014] The objects to be washed include textiles such as clothing, vegetables such as scallop, radish, turnip, Chinese cabbage, leek, spinach, etc., citrus fruits such as tangerine, kumquat, daidai, clams,
It can be used for foods such as clams such as clams, metal or plastic crowns, caps, small parts for medical and food use, and industrial products such as bolts, screws, gears, and small pressed parts. Further, as the object-to-be-cleaned holding means, a mesh-shaped or porous belt or bag, a mesh, a grid, a mesh container or a conveyor made of a punched metal, or the like is used. As the cleaning liquid, water, a detergent aqueous solution, a liquid detergent such as toluene, or the like is used. As the vibration means for vibrating the vibration body up and down, a crank mechanism, a mechanism that vibrates by electromagnetic vibration, a mechanism that vibrates by a cylinder such as an air cylinder, a hydraulic cylinder, a rack and pinion mechanism, a cam and a spring are used. The used mechanism is used.

According to a second aspect of the present invention, there is provided the cleaning mechanism according to the first aspect, wherein one end of the communication pipe is opened at the bottom of the buffer chamber or at a side surface near the bottom to communicate the buffer chamber with the cleaning tank. With this configuration, the following operation can be obtained. (1) Since the buffer chamber is communicated with the washing tank by a communication pipe, in a stationary state (equilibrium state), the air pressure in the buffer chamber is increased due to a difference in height between the upper surface water depth of the diaphragm and the surface water depth in the communication pipe. The pressure is slightly higher than the liquid pressure at the bottom of the cleaning tank. Therefore, in the stationary state (equilibrium state), the pressure in the buffer chamber is slightly higher than the liquid pressure at the bottom of the washing tank, and the diaphragm maintains an equilibrium in a pressurized state. (2) Since the air pressure in the buffer chamber is slightly higher than the water pressure at the bottom of the water tank, a drop in the reactivity of the diaphragm due to the diaphragm hanging down by its own weight is prevented. (3) Since the vibration plate has a slightly pressurized state in the buffer chamber and slightly swells and curves toward the cleaning tank side, the vibration plate can easily follow a high-speed vertical vibration of the vibrator.

Here, it is sufficient that a sufficient amount of air remains in the buffer chamber when water is injected into the washing tank, so that one end of the communication pipe communicates with the bottom of the buffer chamber or a side surface near the bottom. Good.

(2) The pressure in the buffer chamber can be adjusted to an optimum pressure according to the vibration speed of the vibrating body.

Here, when there are N pressure adjusting holes (N> 1), the pressure adjusting hole in the pressure adjusting cap is closed by closing the pressure adjusting hole from the uppermost pressure adjusting hole to the nth (n ≦ N) pressure adjusting hole. The water level can be up to the height of the nth pressure adjustment hole, and the water level adjustment allows the air pressure in the buffer chamber to be adjusted. In addition, even in the case of a single pressure adjusting hole, the pressure adjusting cap itself can be detached and attached, and if a plurality of pressure adjusting caps having the pressure adjusting holes opened at different heights are prepared, similarly, the inside of the buffer chamber can be adjusted. The barometric pressure can be adjusted.

This water flow gradually removes dirt between fibers and details of the machine. Therefore, the water pressure applied to the upper surface of the central part of the diaphragm 4 increases, and the central part of the diaphragm 4 curves toward the buffer chamber 3. On the other hand, the peripheral portion of the diaphragm 4 curves toward the cleaning tank 2. At this time, the vibrator 18 does not contact the pressing belt 16. The buffer chamber 3 is filled with a gas having a high compressibility, and the washing liquid below the vibrator 18 causes the vibrating plate 4 to bend and the buffer chamber 3
Is pushed to the side of. Thereby, the water flow of the cleaning liquid pushed out from the lower part of the vibration body 18 to the periphery is suppressed.

When the vibration body 18 is pulled back upward (FIG. 3
(See (c)), the cleaning liquid below the vibrating body 18 flows upward through the cleaning target 17 through the cleaning target 17. Further, at the same time as the water pressure of the cleaning liquid applied to the upper surface near the central portion of the diaphragm 4 decreases, the elasticity of the diaphragm 4 and the expansion of the gas in the buffer chamber 3 move toward the cleaning tank 2 near the central portion of the diaphragm 4. Bend. It is assumed that the buffer chamber 3 is located below the vibrator 18.
When the vibrating plate 4 is not provided, the washing water below the carry-in roller 8 is pushed out from below the vibrating body 18 to the periphery thereof when the vibrating body 18 is lowered. Therefore, when the vibrating body 18 is lifted, only the negative pressure above the cleaning target 17 causes the cleaning target 1 to be cleaned.
Although a water flow that passes through the object 17 to be cleaned is generated from below to above the nozzle 7, a large negative pressure is generated and the surrounding water is drawn, so that a high cleaning effect is hardly obtained. When the vibrator 18 is vibrated up and down at a high speed, the vibrator 1
A large power is required for rapid displacement and repeated suction of the washing liquid below 8. On the other hand, by disposing the buffer chamber 3 and the vibrating plate 4 below the vibrating body 18, the above operation forms a vertically moving water flow in the cleaning liquid below the vibrating body 18. The water flow extruded at the outlet decreases. At the same time, when the vibrating body 18 is pulled upward, the cleaning object 17
, The flow rate of the cleaning liquid flowing upward through the cleaning target 17 through the cleaning target 17 increases,
The cleaning object 17 below the vibrator 18 is caused by the water flow of the cleaning liquid.
Is effectively washed. Further, since the object 17 to be cleaned is sandwiched between the conveyor belt 13 and the pressing belt 16, it can be prevented from escaping during the cleaning, and the spots of the cleaning can be prevented.
It is also possible to intensively clean a portion to be cleaned.

When the object to be cleaned 17 is made of a material having poor water permeability (for example, industrial products such as bolts or vegetables), the object to be cleaned 1 below the vibrating body 18 due to the vertical vibration of the vibrating body 18.
The vibrating plate 7 is exposed to a violent vertical water flow, but the diaphragm 4 is also deformed in accordance therewith, so that the vibrating body 18 can exert a cleaning effect without causing excessive power load. Since the buffer chamber 3 below the diaphragm 4 is in an atmospheric pressure state when assembled in a closed state, the diaphragm 4 is bent toward the buffer chamber 3 due to the water pressure and the own weight of the cleaning liquid in the buffer chamber 3. The higher the frequency of the vibrator 18, the worse the response. It is also possible to provide an air inlet with a valve in the buffer chamber 3 and pressurize it.
To facilitate management, the bottom of the buffer chamber 3 and the washing tank 2
It is preferable to communicate with the bottom part of the buffer chamber 3 by a communication pipe 5 and pressurize the inside of the buffer chamber 3 using the water pressure of the washing liquid.

In the present embodiment, the vibrating body 18
Is configured to be excited by the crank mechanism,
The vibrating means of the vibrating body 18 is not limited to the crank mechanism, but may be configured to vibrate by electromagnetic vibration, or may be vibrated by a cylinder such as an air cylinder or a hydraulic cylinder, a rack and pinion mechanism, or a cam mechanism. You may comprise so that it may shake. For example, a vibrating means of the vibrating body is supported by a gantry that supports the vibrating body in a vertically movable manner, a spring that is connected to the vibrating body and the gantry and biases the vibrating body upward, and is rotatable by the gantry. And a cam contacting with the upper surface of the vibrating body urged upward by a spring and supported by a spring. Accordingly, the vibrator vibrates vertically in the vertical direction, so that a stable water flow can be formed on the lower surface of the vibrator, and a high cleaning effect can be obtained.
