Description

  The present invention relates to a dry cleaning apparatus that removes deposits such as dust and powder attached to an object to be cleaned using a solid cleaning medium without using a liquid.

  In recent years, in order to meet the demand to realize a resource recycling society, after collecting used product bodies or components of image forming apparatuses such as copying machines, facsimiles, and printers that perform image formation using toner, disassembly, Cleaning, reworking, and reusing as parts, resin materials, etc. are performed.

  In order to reuse the image forming apparatus main body or its component parts, it is necessary to perform a cleaning operation to remove the toner of the adhering fine particle powder. However, reducing the cost and environmental burden required for the cleaning operation is a major issue. It has become.

  For example, in the case of a wet cleaning method using water or a solvent for toner removal, there is a problem that the energy consumption and environmental burden for the treatment of the waste liquid containing deposits and the drying treatment after cleaning are large and costly. It has become.

  Further, in the case of a dry cleaning method using air blow, there is a problem in that a post-process such as manual wiping is further required because the cleaning ability is not sufficient for toner with strong adhesion.

  In addition, the blast cleaning using dry ice has a problem that the running cost is high and the environmental load is large because a large amount of dry ice is consumed.

  To solve this problem, a dry cleaning method that does not use water or solvent is to stir the charged cleaning object together with the elastically deformable contact member in the rotating cylinder, and adhere to the cleaning object while removing electricity. There has been known a technique in which the adhesion force of removed dust is weakened and removed (see, for example, Patent Document 1).

  In addition, a technique is known in which deposits are removed from an object to be cleaned by a blasting apparatus that supplies a granular solid cleaning medium through a transport pipe and mixes it into an air flow (see, for example, Patent Document 2).

In addition, there is known a technique in which an adherent such as dust having a relatively strong adhesive force is separated from an object to be cleaned by contacting and colliding with a cleaning medium accelerated by an air flow ejected from a nozzle (for example, And Patent Document 3).
Japanese Patent No. 3288462 Japanese Patent No. 3468995 JP 2007-029945 A

  However, since the technique described in Patent Document 1 obtains the contact force between the contact member and the object to be cleaned only by stirring, it is difficult to remove dust with strong adhesion, and the cleaning power is not sufficient. there were.

  Moreover, since the technique described in Patent Document 2 uses a granular solid as a cleaning medium, it not only removes the dirt of the cleaning target, but also scrapes the surface of the cleaning target and roughens it into a satin finish. There is a problem that the cleaning object cannot be applied when it is not allowed to be damaged.

  In addition, even if a flaky cleaning medium is used in order not to damage the object to be cleaned, the flaky cleaning medium has poor fluidity compared to a granular solid, and thus a large amount of cleaning medium was used. In this case, there is a problem that the transport pipe is easily blocked, and it is difficult to stably supply the cleaning medium.

  In addition, the technique described in Patent Document 3 is based on the interaction with the airflow (high-speed flight, long dwell time, etc.), the action at the time of contact with or collision with the object to be cleaned (when the flaky cleaning medium is used ( High cleaning quality and cleaning efficiency can be obtained without damaging the object to be cleaned by scraping off the adhering material by the edge of the cleaning medium, rubbing by sliding contact, etc. In addition, since the surface area is large, there is a problem that it easily adheres to the wall surface of the cleaning tank or the like due to electrostatic force or the like.

  In addition, since the cleaning media are likely to be in close contact with each other, there is a problem that they are easily accumulated and accumulated and deposited in a posture along the wall surface of the cleaning tank.

  In addition, since the flaky cleaning medium has a large area, the cleaning medium covers the suction port and the flow path, and is easily clogged.

  In addition, there is a separation means that discharges dust etc. removed from the object to be cleaned to the outside of the cleaning tank even if a large amount of cleaning medium is introduced for the purpose of improving cleaning efficiency by performing cleaning with less energy consumption for a shorter time. The amount of the cleaning medium that contributes to the cleaning (the cleaning medium is the object to be cleaned) because the cleaning medium is blocked and the exhaust from the cleaning tank becomes insufficient, or the cleaning medium accumulates and stays on the bottom of the cleaning tank. The frequency of collisions and contact with the machine may not increase, and there is a limit to improving the cleaning efficiency.

  In addition, when a lamellar cleaning medium is used, both the deposit and the cleaning medium are likely to float in the air, so it is difficult to separate the deposit and the cleaning medium and suck and discharge only the deposit. There was a problem of being.

  The present invention has been made to solve the conventional problems, and prevents the cleaning medium from clogging or staying in the apparatus when dry cleaning is performed using a flaky cleaning medium.

In addition, when general powder, dust, etc. and coatings are targeted as deposits to be removed from the object to be cleaned, the type of cleaning medium and the flow rate of the airflow are appropriately set according to the properties of the object to be cleaned and the deposits. You may choose.

  For example, when the object to be cleaned is easily damaged, if a soft material such as a resin film and a thin material is used as the cleaning medium, the thin piece flexes flexibly so that the object to be cleaned is not damaged.

  In addition, when a strong removal force such as removal of a coating film is required, a strong removal action can be obtained by using a metal flake.

  Next, the configuration will be described.

  As shown in FIG. 1, the cleaning tank 13 surrounds the inner walls 1 a to 1 g for storing the cleaning object 3 and the cleaning medium 5 and the inner walls 1 a to 1 g, and removes adhered substances such as dust removed from the cleaning object 3. It has a double structure including an outer wall 2 confined in a closed space.

  The inner walls 1 a to 1 g are fixed only at a plurality of locations with respect to the outer wall 2 so that they can be freely deformed with respect to the outer wall 2.

  Of the inner walls 1a to 1g, the inner walls 1a and 1b forming the bottom surface are made of a flexible material and can be easily deformed or vibrated.

  For example, the inner walls 1a and 1b formed of a flexible material can be deformed or vibrated by the airflow and wind pressure in the cleaning tank 13 generated by the cleaning medium acceleration nozzle 6.

  By configuring the inner walls 1a and 1b with a flexible material, the cleaning medium 5 attached or deposited on the inner walls 1a and 1b can be easily separated from the inner walls 1a and 1b by deformation or vibration of the inner walls 1a and 1b. it can.

  In addition, it is preferable that the inner walls 1c-1g which form a side surface and an upper surface among the inner walls 1a-1g are also comprised from the flexible material.

  Moreover, it is preferable that the inner walls 1a and 1b have not only flexibility but also stretchability and air permeability.

  Since the inner walls 1a and 1b have air permeability, an air flow can easily enter between the cleaning medium 5 and the inner walls 1a and 1b, and the cleaning medium 5 attached to the inner walls 1a and 1b can be easily separated from the inner walls 1a and 1b. Can do.

  Further, since the inner walls 1a and 1b have elasticity, the deformation amount of the inner walls 1a and 1b can be increased, and the cleaning medium 5 attached to the inner walls 1a and 1b can be reliably separated from the inner walls 1a and 1b. Can do.

  2A and 2B, the dry cleaning apparatus 10 includes a contact member 8, and the contact member 8 collides with or comes into contact with the inner walls 1a and 1b of the cleaning tank 13, whereby the inner walls 1a and 1b. As shown in FIGS. 3 (a) and 3 (b), the dry cleaning apparatus 10 is provided with the airflow injection means 11, and the airflow from the airflow injection means 11 is applied to the inner walls 1a and 1b of the cleaning tank 13. The inner walls 1a and 1b may be deformed or vibrated by collision.

  When configured as described above, the cleaning medium 5 attached or deposited on the inner walls 1a and 1b of the cleaning tank 13 can be more reliably separated from the inner walls 1a and 1b and fluidized.

  When the contact member 8 collides or comes into contact as shown in FIGS. 2A and 2B, the magnitude and speed of deformation or vibration applied to the inner walls 1a and 1b can be set appropriately, and efficient cleaning can be performed. It becomes possible to do.

  On the other hand, as shown in FIGS. 3 (a) and 3 (b), in the case of the collision force of the airflow from the airflow ejecting means 11, the inner walls 1a and 1b can be deformed or vibrated without contact, and the inner walls 1a and 1b are consumed. Can be suppressed.

  It is preferable that the inner walls 1a and 1b are made of nets or nets, or that the inner walls 1a and 1b have air permeability by forming a large number of small holes in the inner walls 1a and 1b. In this case, by providing the inner walls 1a and 1b with air permeability, an air flow easily enters between the cleaning medium 5 and the inner walls 1a and 1b, thereby facilitating separation of the cleaning medium 5 attached or deposited on the inner walls 1a and 1b. be able to.

  By setting the size of the small holes in the inner walls 1a and 1b to such a size that only the cleaning medium 5 and the air flow that have deteriorated and become small can pass, and the normal size cleaning medium 5 cannot pass through, the inner wall 1a, As will be described later, 1b can have a function as a separating unit and a cleaning medium regeneration unit.

  On the other hand, an exhaust port 7 is formed in a part of the outer wall 2 of the cleaning tank 13, and dust and other deposits removed from the object to be cleaned 3 are discharged from the exhaust port 7 to the outside of the cleaning tank 13 together with the air flow. It has become so.

  At the outlet of the exhaust port 7, a filter (not shown) or a suction type dust collector for filtering deposits such as dust is attached. When a suction-type dust collector is attached, the flow velocity inside the exhaust port 7 and the cleaning tank 13 is increased, and the discharge performance of deposits such as dust can be further enhanced.

  The inner walls 1a and 1b of the cleaning tank 13 are made of perforated plates, nets, meshes, etc., and have a large number of openings smaller than the size of the cleaning medium 5, and separation means for separating the cleaning medium 5 and the deposits, and attached It has a function as a cleaning medium regeneration means for regenerating the cleaning medium 5 into a reusable state by separating the kimono. The deposits separated from the cleaning medium 5 are discharged out of the cleaning tank 13.

  A cleaning medium attached or deposited on the inner walls 1a and 1b by making the inner walls 1a and 1b flexible and functioning as a cleaning medium separating means for deforming or vibrating the inner walls 1a and 1b to separate the cleaning medium 5 5 can be easily separated, and even when a large amount of the cleaning medium 5 is used, the inner walls 1a and 1b can be prevented from being blocked.

  A plurality of cleaning medium accelerating nozzles 6 are arranged in a row along the longitudinal direction of the cleaning object 3 below the inner walls 1 a and 1 b of the cleaning tank 13, that is, at the bottom of the cleaning tank 13.

  By disposing the cleaning medium acceleration nozzle 6 at the bottom of the cleaning tank 13, the cleaning medium 5 that has dropped due to gravity automatically gathers at the cleaning medium acceleration nozzle 6, so that efficient cleaning can be performed.

  The cleaning medium acceleration nozzle 6 is supplied with compressed air from a compressed air source such as a compressor, a pressure tank, or a blower (not shown).

  The supply of compressed air to the plurality of cleaning medium acceleration nozzles 6 is automatically opened and closed by an electromagnetic valve or the like controlled by a control device (not shown), so that the airflow of the cleaning medium acceleration nozzles 6 is automatically controlled. You may make it do.

  The cleaning object 3 is held in the cleaning tank 13 by the support member 4.

  The support member 4 holds the cleaning medium 5 freely so that the cleaning target 3 does not fall, and is constituted by, for example, a mesh having a rough mesh.

  In addition, the support member 4 is provided with holding means such as a clamp that holds a part of the cleaning object 3 when the cleaning object 3 is light enough to move under the force of the airflow. Is preferred.

  Further, when the entire surface of the cleaning object 3 is to be cleaned, the support member 4 is preferably configured so that the attitude of the cleaning object 3 can be changed by rotating or the like while holding the cleaning object 3.

  Note that it is preferable to select an appropriate method for the holding means for holding the cleaning object 3 in accordance with the shape and characteristics of the cleaning object 3. Specifically, a screwing method, a pinching and fixing method, or a pin fixing method using a hole of the cleaning object 3 can be used, but the cleaning medium 5 contacts the cleaning object 3. It is desirable to have a structure and shape that do not hinder collision as much as possible.

  Next, the operation will be described.

  Prior to the cleaning operation, the cleaning object 3 is inserted into the cleaning tank 13 through a cleaning medium inlet / outlet (not shown) such as a side surface or an upper surface of the cleaning tank 13, and the cleaning object 3 is supported by the support member 4 as necessary. Then, the cleaning tank 13 is sealed by a holding means such as a clamp (not shown), and the cleaning medium inlet / outlet is closed to seal the inside of the cleaning tank 13. In the case where the cleaning medium inlet / outlet for loading and unloading the cleaning object 3 is provided on the flexible inner walls 1a and 1b, the cleaning medium inlet / outlet is sealed by an appropriate method such as a zipper. 5 can be surely confined in the cleaning tank 13.

  First, compressed air is supplied to the cleaning medium acceleration nozzle 6 to cause the cleaning medium 5 deposited on the upper part of the cleaning medium acceleration nozzle 6 to fly upward and collide with the object to be cleaned 3.

  Next, the flexible inner walls 1a and 1b are deformed and vibrated by the contact member 8 shown in FIGS. 2 (a) and 2 (b), or the air flow injection means 11 shown in FIGS. 3 (a) and 3 (b). Then, the cleaning medium 5 adhered and deposited on the inner walls 1a and 1b is separated and fluidized, and is moved downward by gravity. As a result, a large amount of the cleaning medium 5 is successively supplied to the cleaning medium accelerating nozzle 6 positioned at the lowermost part of the inner walls 1 a and 1 b of the cleaning tank 13 and repeatedly flies toward the cleaning object 3.

  Next, when the cleaning medium 5 contacts or collides with the cleaning object 3 at a high speed, the adhering material adhering to the cleaning object 3 is knocked down. The deposit and the cleaning medium 5 struck down are carried on the air current in the cleaning tank 13 and carried to the inner walls 1a and 1b as cleaning medium regenerating means.

  Next, out of the deposit and the cleaning medium 5 carried in the air current, the deposit passes through the opening holes of the inner walls 1a and 1b as the separating means of the cleaning medium regeneration means and is discharged out of the cleaning tank 13. On the other hand, the deposit transferred from the cleaning object 3 to the cleaning medium 5 is separated from the cleaning medium 5 by the friction when the cleaning medium 5 collides with the inner walls 1a and 1b, and the impact and vibration caused by the collision ( "Regeneration" action of the cleaning medium).

  Next, the cleaning medium 5 falls away from the inner walls 1 a and 1 b and circulates in the cleaning tank 13 again by riding on the air current, or accumulates on the bottom of the inner walls 1 a and 1 b of the cleaning tank 13. When the flexible inner walls 1a and 1b are vibrated or deformed to function as cleaning medium separating means, the cleaning medium 5 can be easily separated from the inner walls 1a and 1b by deformation and vibration of the inner walls 1a and 1b. it can.

  As described above, the cleaning medium 5 is circulated, collided, and regenerated while the flexible inner walls 1a and 1b are deformed and vibrated, so that the cleaning medium 5 is circulated in the cleaning tank 13 to be cleaned. It can be made to collide at high speed and the deposits can be removed.

  Moreover, even if the dust has a relatively strong adhesive force and is difficult to remove by air blow alone, it can be separated from the cleaning object 3 by contact and collision of the cleaning medium 5 flying at high speed.

  In particular, when the flaky cleaning medium 5 is used, high cleaning quality and cleaning efficiency are obtained by the excellent cleaning action of the flaky cleaning medium 5 described above, and the cleaning object 3 is not damaged.

  Further, dust and other deposits transferred from the cleaning object 3 to the cleaning medium 5 are effectively removed by the inner walls 1a and 1b as the cleaning medium regenerating means, and the cleaning medium 5 is always kept clean. The adhering matter transferred to the medium 5 does not adhere again to the cleaning object 3, and high cleaning quality can be obtained.

  As described above, the dry cleaning apparatus 10 according to the present embodiment includes the cleaning object 3 and the inner walls 1a to 1g of the cleaning tank 13 that accommodates the flaky flexible cleaning medium 5 and the cleaning object 3. A cleaning medium accelerating nozzle 6 that jets a high-speed air current to cause the cleaning medium 5 to collide with the object to be cleaned 3 so as to remove the attached deposits, and the inner walls 1a and 1b are made of a flexible material. It is characterized by having.

  With this configuration, the inner walls 1a and 1b that accommodate the cleaning medium 5 and the object to be cleaned 3 are flexible, so that the inner walls 1a and 1b are deformed or vibrated so that the cleaning medium 5 is removed from the inner walls 1a and 1b. Separation is facilitated, and it is possible to prevent the cleaning medium 5 from adhering to and accumulating on the inner walls 1a and 1b and staying therein, thereby preventing the cleaning efficiency from decreasing.

  Therefore, when dry cleaning is performed using the flaky cleaning medium 5, the cleaning medium 5 is prevented from clogging or staying in the apparatus, and more cleaning medium 5 can be cleaned 3. The cleaning efficiency can be improved by making it collide.

  Further, the dry cleaning apparatus 10 according to the present embodiment is characterized in that the inner walls 1a and 1b further have air permeability.

  With this configuration, the inner walls 1a and 1b have flexibility and air permeability, so that an air flow easily enters between the cleaning medium 5 and the inner walls 1a and 1b, and the cleaning medium 5 attached to the inner walls 1a and 1b is removed from the inner wall. It can be easily separated from 1a, 1b.

  Further, the dry cleaning apparatus 10 according to the present embodiment is characterized in that the inner walls 1a and 1b further have elasticity.

  With this configuration, since the inner walls 1a and 1b have flexibility and stretchability, the deformation amount of the inner walls 1a and 1b can be increased, and the cleaning medium 5 attached to the inner walls 1a and 1b can be removed from the inner walls 1a and 1b. Can be reliably separated.

  In addition, the dry cleaning apparatus 10 according to the present embodiment includes a contact member 8 or an airflow ejecting unit 11 that deforms or vibrates the inner walls 1a and 1b to separate the cleaning medium 5 from the inner walls 1a and 1b. .

  With this configuration, the cleaning medium 5 can be separated from the inner walls 1a and 1b by deforming or vibrating the inner walls 1a and 1b. Therefore, the cleaning medium 5 staying on the inner walls 1a and 1b is reduced, and the cleaning medium is accelerated. By increasing the cleaning medium 5 supplied to the nozzle 6, the cleaning medium 5 can be effectively contributed to cleaning, so that cleaning efficiency can be improved.

  Further, the dry cleaning apparatus 10 according to the present embodiment is characterized in that the cleaning medium acceleration nozzle 6 is disposed at the bottom of the inner walls 1a and 1b.

  With this configuration, since the cleaning medium acceleration nozzle 6 is arranged at the bottom of the inner walls 1a and 1b, the cleaning medium 5 separated from the inner walls 1a and 1b naturally gathers near the cleaning medium acceleration nozzle 6 by gravity. A large amount of the cleaning medium 5 can be supplied to the cleaning medium acceleration nozzle 6 while suppressing energy consumption for supplying 5 to the cleaning medium acceleration nozzle 6.

  In addition, even if the inclination angle of the bottom surfaces of the inner walls 1a and 1b is reduced, the cleaning medium 5 is less likely to stay due to deformation and vibration of the inner walls 1a and 1b, so that the distance between the cleaning medium acceleration nozzle 6 and the cleaning object 3 can be reduced. The ability to remove deposits can be improved.

  Further, the dry cleaning apparatus 10 according to the present embodiment has a contact member 8 that deforms or vibrates the inner walls 1a and 1b by contacting the wall surfaces of the inner walls 1a and 1b.

  With this configuration, by having the contact member 8 that deforms or vibrates the inner walls 1a and 1b by contacting the inner walls 1a and 1b, the magnitude and speed of deformation or vibration applied to the inner walls 1a and 1b can be appropriately set. , Efficient cleaning becomes possible.

  In addition, the dry cleaning apparatus 10 according to the present embodiment is characterized by having an airflow ejecting means 11 that deforms or vibrates the inner walls 1a and 1b by injecting an airflow onto the inner walls 1a and 1b.

With this configuration, the inner walls 1a and 1b can be deformed or vibrated in a non-contact manner by deforming or vibrating the inner walls 1a and 1b by injecting an air flow onto the inner walls 1a and 1b, thereby reducing the consumption of the inner walls 1a and 1b. Can be suppressed.
(Second Embodiment)
4 (a) and 4 (b) are cross-sectional views showing the configuration of the dry cleaning apparatus according to the second embodiment of the present invention. 4A is a BB arrow view of FIG. 4B, and FIG. 4B is an AA arrow view of FIG. 4A. In the present embodiment, an example will be described in which the cleaning medium is allowed to fly upward by colliding the contact member, or the high-speed airflow is intermittently ejected in synchronization with the collision. In addition, the same code | symbol is attached | subjected to the structure similar to the above-mentioned embodiment, and description is abbreviate | omitted.

  As shown in FIGS. 4A and 4B, the cleaning tank 13 has a double structure including the outer wall 2 and the flexible inner wall 1a, as in the first embodiment. The flexible inner wall 1a is made of a material such as a net or a porous film so that only the adhering matter such as dust passes and the cleaning medium 5 does not pass.

  The cleaning medium acceleration nozzle 6 is arranged on the side surface of the cleaning tank 13 and blows a high-speed air stream toward the cleaning target 3.

  A contact member 8 that contacts the flexible inner wall 1a and a contact member driving means 9 that drives the contact member 8 are disposed at the bottom of the cleaning tank 13 so as to splash the cleaning medium 5 upward. .

  The contact member driving means 9 is composed of an air cylinder, a spring, a motor, and the like. The contact member 8 collides with the flexible inner wall 1a, and a large amount of the cleaning medium 5 deposited on the bottom of the inner wall 1a is brought into the air. It is supposed to fly.

  The cleaning object 3 is held by a rod-shaped support member 4 inserted into the hole. For this reason, by rotating the support member 4, the cleaning object 3 can be rotated and the entire surface of the cleaning object 3 can be cleaned. Alternatively, the cleaning target 3 may be held rotatably with respect to the rod-shaped support member 4, and the cleaning target 3 may be rotated on the support member 4 by the air current of the cleaning medium acceleration nozzle 6.

  Next, the operation will be described.

  First, the cleaning medium 5 flying into the air by the contact member 8 is accelerated by the air current of the cleaning medium acceleration nozzle 6 and collides with the cleaning object 3 at a high speed. Since the lamellar cleaning medium 5 is lightweight and has a large area, it is easily accelerated by the airflow. Even when a large amount of the cleaning medium 5 is used, the power required for driving the contact member 8 is small because the mass is small.

  Next, the cleaning medium 5 that has collided with the cleaning object 3 separates the adhering material such as dust attached to the cleaning object 3 from the cleaning object 3. The separated deposits ride on the air current, pass through the inner wall 1a of the cleaning tank 13, and are discharged out of the cleaning tank 13 through the exhaust port 7. Also, the deposits transferred from the cleaning object 3 to the cleaning medium 5 are separated from the cleaning medium 5 by contact between the cleaning media 5 and the inner wall 1a of the cleaning tank 13, and are washed from the exhaust port 7 by riding on an air current. It is discharged out of the tank 13.

  As described above, in the dry cleaning apparatus 10 according to the present embodiment, the cleaning medium accelerating nozzle 6 is disposed in the cleaning tank 13 by the contact member 8 colliding with the flexible inner wall 1a and causing the cleaning medium 5 to fly. Even when not disposed near the bottom surface, the cleaning medium 5 can be supplied to the cleaning medium acceleration nozzle 6.

  In addition, since a large amount of the cleaning medium 5 deposited on the bottom of the inner wall 1a of the cleaning tank 13 can be supplied to the cleaning medium acceleration nozzle 6, it is possible to obtain high cleaning efficiency by suppressing the consumption of compressed air, so that compressed air is generated. The energy consumption for doing so is small, and dry cleaning with a smaller environmental load can be performed.

  Note that if the cleaning medium acceleration nozzle 6 is intermittently driven to generate or stop the air flow in accordance with the timing of the cleaning medium 5 flying by the contact member 8, the consumption of compressed air can be further reduced.

  As described above, the dry cleaning apparatus 10 according to the present embodiment is characterized in that the cleaning medium 5 is caused to fly when the contact member 8 collides with the inner walls 1a and 1b.

  With this configuration, the contact member 8 collides with the inner walls 1a and 1b and causes the cleaning medium 5 to fly, so that even when the cleaning medium acceleration nozzle 6 is not near the bottom of the inner walls 1a and 1b, the cleaning medium acceleration nozzle 6 is cleaned. Media can be supplied.

  Further, the dry cleaning apparatus 10 according to the present embodiment is characterized in that the cleaning medium acceleration nozzle 6 intermittently jets a high-speed air flow in synchronization with the collision of the contact member 8 with the inner walls 1a and 1b.

With this configuration, the cleaning medium accelerating nozzle 6 intermittently injects a high-speed air flow in synchronization with the collision of the contact member 8 with the inner walls 1a and 1b, so that cleaning is performed only when a large amount of the cleaning medium 5 is supplied. Since airflow can be supplied to the medium acceleration nozzle 6, the amount of compressed air consumed by the cleaning medium acceleration nozzle 6 can be reduced, and cleaning with energy saving can be achieved.
(Third embodiment)
FIGS. 5A and 5B are cross-sectional views showing the configuration of a dry cleaning apparatus according to the third embodiment of the present invention. FIGS. 6A and 6B are cross-sectional views showing the operation of the dry cleaning apparatus. 7A and 7B are cross-sectional views showing other examples of the operation of the dry cleaning apparatus. 5A is a BB arrow view of FIG. 5B, and FIG. 5B is an AA arrow view of FIG. 5A. In this embodiment, an example in which the flexible inner wall is moved or inclined by moving the cleaning medium acceleration nozzle will be described. In addition, the same code | symbol is attached | subjected to the structure similar to the above-mentioned embodiment, and description is abbreviate | omitted.

  As shown in FIG. 5, the dry cleaning apparatus 10 includes a plurality of cleaning medium acceleration nozzles 6 a to 6 c at the bottom of the cleaning tank 13.

  Moreover, as shown to FIG. 6 (a), (b), FIG. 7 (a), (b), the washing | cleaning tank 13 can change the attitude | position or position.

  As a means for changing the posture or position of the cleaning tank 13, for example, an actuator 6d such as a motor or an air cylinder can be used.

  The cleaning medium acceleration nozzles 6 a to 6 c are configured to be able to change the posture and position, that is, swing (swing) and reciprocate (parallel movement), and cover a wide area of the cleaning object 3. It has become.

  The flexible inner walls 1a and 1b are fixed to the cleaning medium acceleration nozzles 6a to 6c, and the flexible inner walls 1a and 1b are deformed by swinging or reciprocating movement of the cleaning medium acceleration nozzles 6a to 6c. It comes to vibrate.

  When the cleaning medium acceleration nozzles 6a to 6c are swung or moved slowly, the piles of the cleaning medium 5 deposited on the flexible inner walls 1a and 1b can be broken.

  Further, when the cleaning medium accelerating nozzles 6a to 6c are swung or moved at a high speed with a large amplitude, the flexible inner walls 1a and 1b are suddenly deformed, and the ridges of the cleaning medium 5 deposited on the inner walls 1a and 1b. Can be jumped up into the air.

  When the cleaning medium acceleration nozzles 6a to 6c are swung or moved at a high speed with a small amplitude, the inner walls 1a and 1b and the cleaning medium 5 are affected by the vibration generated in the flexible inner walls 1a and 1b. Since the friction between them and the friction between the cleaning media 5 are reduced and the fluidity is increased, the crests of the cleaning media 5 deposited on the inner walls 1a and 1b can be broken and moved.

  Next, the operation will be described.

  First, as shown in FIG. 6A, the cleaning medium acceleration nozzles 6a to 6c are moved, rocked and vibrated, and the flexible inner walls 1a and 1b are deformed and vibrated.

  In the state shown in FIG. 6 (a), the entire cleaning tank 13 is inclined to the lower left and the cleaning medium acceleration nozzle 6c side is lowered, so that the cleaning medium 5 deposited on the flexible inner walls 1a and 1b is The inner wall 1a, 1b is gradually moved to the cleaning medium acceleration nozzle 6c side by deformation, vibration and gravity.

  Next, by supplying the compressed air to the cleaning medium acceleration nozzles 6b and 6c, the cleaning medium 5 is accelerated by the cleaning medium acceleration nozzles 6b and 6c one after another while moving on the inclined surface, and flies toward the cleaning target 3. .

  The cleaning medium 5 that has collided with the cleaning target object 3 falls downward due to gravity, and again flies toward the cleaning target object 3 by the airflow from the cleaning medium acceleration nozzles 6b and 6c. Or the washing | cleaning medium 5 isolate | separates a deposit | attachment on the surface of the air permeable inner walls 1a and 1b which are separation means, and falls below.

  In this way, by causing the flexible inner walls 1a and 1b to function as cleaning medium separating means, the cleaning medium 5 can be separated from the inner wall 1a by deformation and vibration of the inner walls 1a and 1b. It can prevent that it adheres to 1a and 1b and obstruct | occludes the inner wall 1a.

  Since a large amount of the cleaning medium 5 has moved to the cleaning medium acceleration nozzle 6c side after the predetermined time has elapsed, the attitude of the entire cleaning tank 13 is changed to a right-downward attitude as shown in FIG. 6B.

  In this case, since the cleaning medium acceleration nozzle 6a side is lowered, the cleaning medium 5 deposited on the inner walls 1a and 1b is moved to the cleaning medium acceleration nozzle 6a side by the deformation of the inner walls 1a and 1b, the action of vibration and the action of gravity. Moving.

  Next, by supplying compressed air to the cleaning medium acceleration nozzles 6 a and 6 b, the cleaning medium 5 is accelerated by the cleaning medium acceleration nozzles 6 a and 6 b one after another while moving on the inclined surface, and flies toward the cleaning object 3. .

  Thereafter, by repeating the state of lowering right shown in FIG. 6A and the state of lowering left shown in FIG. 6B, a large amount of the cleaning medium 5 is supplied to the cleaning medium acceleration nozzles 6a to 6c one after another. Wash.

  As described above, the bottom surfaces of the flexible inner walls 1a and 1b are inclined surfaces, and a plurality of cleaning medium accelerating nozzles 6a to 6c are arranged in the middle or at the bottom, and the inner walls 1a and 1b are deformed and vibrated, thereby cleaning. Even if the amount of the medium 5 is large, the accumulated cleaning medium 5 can be moved and supplied to the cleaning medium acceleration nozzles 6a to 6c.

  That is, since the cleaning medium 5 staying on the wall surface and the bottom surface can be reduced and effectively contributed to the cleaning, the cleaning efficiency can be improved.

  Moreover, even if the inclination of the bottom surface of the cleaning tank 13 is small, the accumulated cleaning medium 5 can be broken and the stay can be eliminated, so that the height of the cleaning tank 13 can be kept low, and the cleaning medium acceleration nozzles 6a to 6c can be reduced. Since the distance to the cleaning medium 5 can be reduced, a high cleaning ability can be obtained.

  Moreover, since the moving direction of the cleaning medium 5 is switched by reversing the inclination of the cleaning tank 13, the cleaning medium 5 does not stay in one place.

  Therefore, a sufficient amount of the cleaning medium 5 to be supplied to the cleaning medium acceleration nozzles 6a to 6c can be secured, and the cleaning efficiency can be improved.

  Instead of changing the attitude of the entire cleaning tank 13 and switching the inclination of the bottom surface, as shown in FIGS. 7A and 7B, the relative heights of the cleaning medium acceleration nozzles 6a to 6c are set for each nozzle. It is also possible to change the inclination of the bottom surface by changing independently.

  That is, among the cleaning medium acceleration nozzles 6a to 6c, if the relative height of the nozzle to which the cleaning medium 5 is desired to be supplied is reduced, the cleaning medium 5 can be collected toward the nozzle. It is possible to intensively clean a part 3 to be cleaned, and to improve the cleaning efficiency.

  As described above, the dry cleaning apparatus 10 according to the present embodiment attaches the cleaning medium acceleration nozzles 6a to 6c to the inner walls 1a and 1b, and includes the actuator 6d that changes the posture or position of the cleaning medium acceleration nozzles 6a to 6c. It is characterized by providing.

  With this configuration, the inner walls 1a and 1b are deformed or vibrated in the same manner as the contact member 8 and the airflow ejecting means 11 by changing the posture or position of the cleaning medium acceleration nozzles 6a to 6c attached to the inner walls 1a and 1b. Therefore, the cleaning medium can be separated from the inner walls 1a and 1b with a small number of components.

  In addition, the dry cleaning apparatus 10 according to the present embodiment has the cleaning medium acceleration nozzles 6a to 6c attached to the bottom wall surfaces of the inner walls 1a and 1b, and the cleaning medium acceleration nozzles 6a to 6c having different heights. 6d is provided.

With this configuration, the inclination of the wall surfaces of the bottom portions of the inner walls 1a and 1b can be changed by making the heights of the cleaning medium acceleration means attached to the bottom wall surfaces of the inner walls 1a and 1b different. Due to the change, it is possible to concentrate the cleaning medium 5 on the desired cleaning medium acceleration nozzles 6a to 6c and perform cleaning efficiently.
