Description

  The present invention relates to a dry cleaning apparatus and a dry cleaning method for removing an adhering matter such as dust or 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 a charged cleaning object together with an elastically deformable contact member in a rotating cylinder, and adhere to the cleaning target member 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 with a blast device (see, for example, Patent Document 2).

In addition, a technique is known in which deposits are removed from an object to be cleaned by a blasting measure in which a granular solid cleaning medium is supplied through a transport pipe and mixed into an air flow (see, for example, Patent Document 3).
Japanese Patent No. 3288462 Japanese Patent No. 2889547 Japanese Patent No. 3468995

  However, since the technique described in Patent Document 1 cannot control the posture of the object to be cleaned because the object to be cleaned is not fixed, the target object of the object to be cleaned cannot be cleaned, Since the contact force between the contact member and the object to be cleaned is obtained only by stirring, there is a problem that the cleaning force is not sufficient.

  Further, since the contact members cannot be forcibly replaced only by stirring, the contact members always interfere with each other, and the contact frequency of the contact members with respect to the object to be cleaned cannot be increased, and the adhesion force is strong. There was a problem that it was difficult to remove dust.

  Furthermore, since the contact member that has been removed by removing dust and stays around the object to be cleaned for a long time, the dust reattaches to the object to be cleaned, and the cleaning speed and quality cannot be increased, resulting in an increase in tact. There was a problem that.

  Further, in the technique described in Patent Document 2, when a flaky cleaning medium is used, both the deposit and the cleaning medium are likely to float in the air. There was a problem that it was difficult to suck and discharge only the adhered matter.

  In addition, since the technique described in Patent Document 3 uses a granular solid as a cleaning medium, it not only removes dirt on the object to be cleaned, but also scrapes the surface of the object to be cleaned and roughens it into a satin finish. It is not suitable when the object to be cleaned is not allowed to be scratched. Even if a flaky cleaning medium is used, the flaky cleaning medium has a poor flowability compared to a granular solid, When the cleaning medium is used, there is a problem that the transport pipe is easily clogged and it is difficult to stably supply the cleaning medium.

  Even if the cleaning medium can be stably supplied, when the flaky cleaning medium is used, the cleaning medium needs to collide with the object to be cleaned at a high speed and with a high frequency in order to improve the cleaning performance. However, there is a problem that the cleaning time and the removal ability are insufficient for the object to be cleaned on which the dirt adheres with strong adhesion.

  In addition, since air flow is generated also in portions other than the cleaning medium that directly contributes to cleaning, there is a problem that excessive compressed air is consumed and reduction of environmental load is insufficient.

  In addition, the flake-like cleaning medium has the property that if it stays once and is laminated, the fluidity is remarkably deteriorated. Therefore, a large amount of air flow is required to move the laminating cleaning medium only by the stirring action by the airflow. There was a problem to do.

  The present invention has been made to solve the conventional problems, and the speed and frequency at which the cleaning medium collides with the object to be cleaned while separating and recycling the flaky cleaning medium to which the deposit has transferred from the deposit.

  Therefore, the flaky cleaning medium to which the deposits have been transferred is separated from the deposits and reused while increasing the speed and frequency at which the cleaning medium collides with the object to be cleaned, and wasteful compressed air consumption is reduced. It is possible to suppress the cleaning quality and cleaning efficiency.

  Further, in the dry cleaning apparatus according to the present invention, the circulating means moves the inner wall of the cleaning tank or a part of the inner wall for storing the object to be cleaned and the cleaning medium, and the cleaning medium is moved to the cleaning medium.

The cleaning medium can be regenerated by separating and removing the deposits such as powder and powder and the deposits transferred to the cleaning medium.

  Further, by keeping the space between the inner wall and the outer wall at a negative pressure, it is possible to prevent the removed deposits such as dust and powder from returning to the inside of the cleaning tank.

  In addition, since the cleaning medium can be regenerated over a wide area using the inner wall of the cleaning tank, the cleaning medium can be regenerated powerfully and reliably.

  The dry cleaning apparatus according to the present invention is characterized in that the cleaning medium accelerating means is disposed outside the inner wall of the cleaning tank.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a perspective view showing a configuration of a dry cleaning apparatus according to a first embodiment of the present invention, and FIGS. 2A to 2C are cross-sectional views showing a cleaning action. FIG. 3 is a cross-sectional view showing the configuration of the dry cleaning apparatus, and FIGS. 4A to 4C are cross-sectional views showing the shapes of protrusions of the dry cleaning apparatus. 5 (a) and 5 (b) are a perspective view and a cross-sectional view showing the configuration of the cleaning medium regeneration means of the dry cleaning apparatus, and FIGS. 6 (a) and 6 (b) are cleaning tanks of the dry cleaning apparatus. It is sectional drawing which shows this structure. FIG. 7 is a cross-sectional view showing the configuration around the side wall of the dry cleaning apparatus.

  First, the configuration will be described.

  As shown in FIG. 1, the dry cleaning apparatus 10 is configured to remove an adhering material 19 made of various dusts such as toner adhering to an object 1 to be cleaned by a cleaning medium 20 that flows by a high-speed air current. A tank 40, a circulation means 22, a cleaning medium acceleration means 12, and a cleaning medium regeneration means 30 are provided.

  The cleaning medium 20 used in the dry cleaning apparatus 10 is a flexible material formed of a metal, ceramics, synthetic resin, sponge, cloth or the like formed into a granular shape, a rod-shaped, cylindrical, fibrous or flaky solid. The material and shape are selected according to the characteristics of the shape and material of the object 1 to be cleaned and the particle size and adhesion strength of the object 19 attached to the object 1 to be cleaned. Can do.

  Further, as the cleaning medium 20, it is preferable that the above-mentioned material is formed into a thin piece having an area of 1 to 1000 square meters and a thickness of about 1 to 500 μm. Hereinafter, the cleaning medium 20 is flexible. It demonstrates as what is comprised from what formed the material in thin piece shape.

  For example, in order to remove the deposit 19 from a synthetic resin or metal component in which toner powder having an average particle diameter of 5 to 10 μm used as an electrophotographic image forming apparatus is deposited as the deposit 19, a resin film piece is used. It is desirable to use a thin piece of cloth, cloth, paper, metal flake or the like as the cleaning medium 20.

  As shown in FIG. 2A to FIG. 2C, when the laminar cleaning medium 20 is used, when the cleaning medium 20 collides with the cleaning object 1 from the end thereof, the contact with the cleaning object 1 occurs. Since the force concentrates on the end portion of the cleaning medium 20, the force necessary for removing the deposit 19 can be obtained even if the mass of the cleaning medium 20 is small.

  Further, when the flaky cleaning medium 20 is used, the cleaning medium 20 is bent and the force is released when the contact force with respect to the cleaning object 1 is increased, so that a general blast shot material or an abrasive for barrel processing is cleaned. Unlike the case where it is used as a medium, an unnecessary force is not applied to the object 1 to be cleaned, and the object 1 to be cleaned is not damaged.

  Furthermore, the flake-like cleaning medium 20 is inelastic when it collides with the object 1 to be cleaned and the viscous resistance received from the air acts on the object, so that it does not easily bounce off the object 1 to be cleaned. In the case of a slanting collision, the object moves while contacting a large area of the object 1 to be cleaned in a single collision, and the adhering substance adhering to the object 1 to be cleaned by the scraping action or the rubbing action due to this contact. A force parallel to the contact surface is applied to 19 and the deposit 19 can be separated from the object to be cleaned 1 with a small force, and the cleaning efficiency can be increased.

  The cleaning tank 40 is configured as a cylindrical hollow body as viewed from the side, and has a cleaning object input port 14 for supplying the cleaning object 1 to the side wall 47, and the cleaning object input port 14 has an openable / closable lid. 50 (see FIG. 7) is provided.

  An opening 40a is formed in a part of the inner wall of the cleaning tank 40 in the circumferential direction, and the cleaning medium regeneration means 30 is provided in the opening 40a.

  Further, the cleaning tank 40 is provided with a circulation means 22 (see FIG. 3), and the circulation means 22 uses the vicinity of the inner surface of the inner wall in the circumferential direction as the circulation path 18 of the cleaning medium 20.

  The shape of the cleaning tank 40 is preferably a rotationally symmetric cylindrical shape, and a cylindrical shape is most ideal.

  As shown in FIG. 3, the circulation means 22 includes a protrusion 42 for preventing the drop when the cleaning medium 20 is conveyed upward, and a rotation motor 15 that rotates the cleaning tank 40.

  As shown in FIGS. 4A to 4C, the protrusion 42 is formed in a shape that allows the cleaning medium 20 to be transported upward without dropping. For example, FIG. 4 can be used, or a fin-like one shown in FIG. 4B, or a fin-like one in which the shielding plate 43 is fixed as shown in FIG. 4C. Among these, the uneven protrusion 42 shown in FIG. 4A and the fin-like protrusion 42 shown in FIG. 4B are preferable because they have a good workability.

  When the cleaning tank 40 is rotated (for example, clockwise as indicated by an arrow A in FIG. 1), the protrusion 42 directly conveys the cleaning medium 20 deposited on the inner lower portion of the inner wall of the cleaning tank 40 upward. ing.

  For this reason, although it changes with the magnitude | sizes of the washing tank 40 compared with the case where compressed air is ejected from an air blow nozzle and it conveys the washing | cleaning medium 20 indirectly, about 10 to 50% of energy can be reduced.

  The cleaning medium accelerating means 12 includes an accelerating nozzle 12a, and jets compressed air supplied from a compressed air source (not shown) such as a compressor or a pressure tank from the accelerating nozzle 12a toward the cleaning target 1, thereby cleaning the cleaning medium 20. Is made to collide with the object 1 to be cleaned.

  As shown in FIGS. 5A and 5B, the cleaning medium regenerating unit 30 has a closed space 30 a formed by a separation member 31 and a hood 32 arranged on a part of the inner wall of the cleaning tank 40 in the circumferential direction. The closed space 30a is connected to a dust collector 16 having a negative pressure generation source by a suction pipe 17 such as a hose, and the inside of the hood 32 is maintained at a negative pressure.

  The separation member 31 has a large number of small holes 31a through which gas or powder can pass but the cleaning medium 20 cannot pass through. For example, the separation member 31 is formed of a porous member made of a metal mesh, a plastic mesh, a mesh, a punch metal plate, a slit plate, or the like. Then, the deposit 19 separated from the cleaning object 1 and the cleaning medium 20 that collides with the cleaning object 1 and wears or chipped or deteriorates in elasticity due to long-term use are discharged to the outside of the cleaning tank 40. It has become. The small hole 31a is not limited to a circular shape, and may be a slit shape.

  As shown in FIGS. 6A and 6B, the cleaning tank 40 has a small hole 45 a similar to the small hole 31 a of the separation member 31 on the inner wall 45 of the circumferential wall surface of the cleaning tank 40. By constructing a multi-layered structure in which a large number of porous members are formed and a closed space 40 b is formed between the outer wall 46 and the outer wall 46, the entire outer periphery of the cleaning tank 40 can be configured as the cleaning medium regeneration means 30.

  In this case, the cleaning medium 20 can always be regenerated while the cleaning medium 20 is being conveyed, and a high dust collection effect and high cleaning quality can be obtained.

  As shown in FIG. 7, the cleaning tank 40 has a shaft 61 through which the cleaning object insertion port 14 of the side wall 47 is inserted, and holds the cleaning object 1 at the center of the cleaning tank 40. Holding means 62 is provided.

  A seal 48 for sealing the inside of the cleaning tank 40 is provided between the lid 50 and the side wall 47 and between the lid 50 and the shaft 61. Further, a bearing 49 is provided between the lid 50 and the shaft 61 to prevent both wear.

  The shaft 61 of the cleaning object holding means 62 is composed of a motor or the like, and is connected to a posture moving means 60 that rotates the shaft 61 and the cleaning object holding means 62. The posture moving means 60 rotates the cleaning object holding means 62 around the axis of the shaft 61 so as to rotate the cleaning object 1 held by the cleaning object holding means 62 and change its attitude. It has become.

  Next, the operation will be described.

  First, in a state where the flaky cleaning medium 20 is put into the cleaning tank 40, the cleaning target 1 held by the cleaning target holding means 62 is supplied from the cleaning target input port 14 of the cleaning tank 40 to the initial position. After positioning, the cleaning object inlet 14 is closed with a lid 50 to seal the cleaning tank 40.

  Next, when the circulation means 22 is operated, the cleaning medium 20 that has fallen to the bottom surface in the cleaning tank 40 in the initial state rises by the protrusions 42 along the wall surface of the cleaning tank 40 that is the circulation path 18, and near the top. , It is dropped by gravity and is carried to the cleaning medium acceleration means 12. That is, a circulation process is performed.

  Next, when compressed air is supplied to the cleaning medium accelerating means 12, the falling cleaning medium 20 is accelerated in the direction of the cleaning object 1 and collides with the cleaning object 1 at a high speed. That is, a cleaning medium acceleration process is performed.

  Next, the cleaning object 1 is rotated by the attitude moving means 60 to change the relative position of the accelerating nozzle 12a of the cleaning object 1 and the cleaning medium accelerating means 12, so that the cleaning medium is uniformly applied to the entire surface of the cleaning object 1. 20 collides.

  Next, when the cleaning medium 20 contacts or collides with the object 1 to be cleaned at a high speed, the deposit 19 attached to the object 1 to be cleaned is knocked down. The deposit 19 and the cleaning medium 20 that have been struck down fall due to gravity and return to the bottom surface of the cleaning tank 40, and then are carried to the cleaning medium regenerating means 30.

  Next, the cleaning medium 20 to which the deposit 19 has been transferred is sucked to the separation member 31 of the cleaning medium regenerating unit 30 on the flow of the air flow toward the dust collector 16. The deposit 19 that has been peeled off from the object to be cleaned 1 passes through the separation member 31 and is discharged from the cleaning tank 40. Also, the deposit 19 transferred from the cleaning object 1 to the cleaning medium 20 is separated from the cleaning medium 20 by the separation member 31 and discharged from the cleaning tank 40. That is, a regeneration process is performed.

  Next, the cleaning medium 20 from which the deposit 19 has been separated after passing through the cleaning medium regeneration means 30 is conveyed again to the cleaning medium acceleration means 12 by the circulation means 22.

  By repeating this cycle with the above series of operations as one cycle, the deposit 19 can be effectively removed from the object 1 to be cleaned while circulating the cleaning medium 20 in the cleaning tank 40.

  Further, according to this configuration, even if the deposit 19 has a relatively strong adhesion and is difficult to remove by air blow alone, the cleaning medium 20 flying at high speed comes into contact with and collides with the object to be cleaned. 1 can be separated.

  In particular, when the lamellar cleaning medium 20 is used, there is an excellent effect that higher cleaning quality and cleaning efficiency can be obtained without damaging the cleaning object 1.

  Furthermore, since the deposit 19 transferred to the cleaning medium 20 is effectively removed by the cleaning medium regeneration means 30 and the cleanliness of the cleaning medium 20 is always maintained, the deposit transferred from the cleaning object 1 to the cleaning medium 20 is maintained. 19 does not reattach to the cleaning object 1, and high cleaning quality can be obtained.

  A plurality of shafts 61 and posture moving means 60 connected to the cleaning object holding means 62 are provided, and a plurality of postures of the cleaning object 1 held by the cleaning object holding means 62 by the plurality of shafts 61 and posture moving means 60 are provided. By repeating the above operation while changing the rotation around the axis, it is possible to further eliminate unevenness in cleaning and obtain high cleaning quality.

  As described above, the dry cleaning apparatus 10 according to the present embodiment includes the cleaning object 40 and the cleaning tank 40 that accommodates the cleaning medium 20 that is formed in a thin piece and has flexibility and cleans the cleaning object 1. The cleaning medium accelerating means 12 that causes the cleaning medium 20 flying in the cleaning tank 40 to collide with the cleaning target object 1 by the high-speed air current so as to remove the dust and the powdered deposits 19 attached to the cleaning target object 1, and the cleaning The adhering matter 19 that has collided with the object 1 and transferred to the cleaning medium 20 is sucked and removed from the cleaning medium 20, so that the cleaning medium regenerating means 30 for regenerating the cleaning medium 20 and the cleaning tank 40 are provided. Circulation means 22 for conveying the accommodated cleaning medium 20 to the cleaning medium acceleration means 12, and the circulation means 22 moves on the wall surface of the cleaning tank 40 that accommodates the cleaning object 1 and the cleaning medium 20, thereby cleaning the cleaning medium. 20 is added to the washing medium It is characterized by conveying to means 12.

  For this reason, a large amount of the cleaning medium 20 deposited in the cleaning tank 40 can be forcibly transported to the cleaning medium accelerating means 12 by moving the wall surface of the cleaning tank 40 that accommodates the cleaning object 1 and the cleaning medium 20. it can.

  In addition, the energy required for transportation is smaller than that of transportation by compressed air current, and the environmental load in the cleaning process can be reduced.

  Accordingly, the flaky cleaning medium 20 to which the deposit 19 has been transferred is separated from the deposit 19 and circulated and reused to increase both the speed and frequency at which the cleaning medium 20 collides with the object 1 to be cleaned, and wasted. The consumption of compressed air can be suppressed and the cleaning quality and cleaning efficiency can be improved.
