DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, the configuration of an image forming apparatus that uses a roll brush will be described.
[0009]
FIG. 5 conceptually shows the image forming apparatus. In the image forming apparatus, the photosensitive drum 11 as a movable body is rotatably supported by a support shaft 11a, and the surface thereof can be charged. Around the photosensitive drum 11, a charging unit 12, an exposure unit 13, a developing unit 14, a transfer unit 16, and a cleaning unit 18 are arranged in order from the upper position toward the rotation direction. The charging unit 12, the developing unit 14, and the cleaning unit 18 are respectively provided with a charging brush 12a, a developing brush 14a, and a cleaning brush 18a formed from a roll brush. The charging brush 12a, the developing brush 14a, and the cleaning brush 18a are supported in each portion so as to be able to rotate while their respective surfaces are in sliding contact with the surface of the photosensitive drum 11.
[0010]
The surface of the photosensitive drum 11 is charged by the charging brush 12a and an electrostatic latent image is formed by the exposure unit 13, and then toner 15 as fine powder is supplied from the developing brush 14a. Then, after the visible image by the toner 15 is transferred to the recording paper 17 supplied between the photosensitive drum 11 and the transfer unit 16 by the transfer unit 16, the toner 15 remaining on the surface of the photosensitive drum 11 is removed by the cleaning brush 18a. At the same time, the remaining charge is erased and the charge is eliminated. That is, the charging brush 12a, the developing brush 14a, and the cleaning brush 18a formed from a roll-shaped brush exhibit their specific functions such as charging of the photosensitive drum 11, supply of the toner 15, removal of the toner 15, and charge removal. It has become.
[0011]
Next, the configuration of the roll brush will be described.
As shown in FIGS. 3 and 4, the roll-shaped brush 20 (hereinafter also simply referred to as the brush 20) includes a support shaft 21 made of a metal round bar such as aluminum, stainless steel, or nickel-plated iron. It is comprised from the velor material 22 which makes the strip | belt shape joined to the surface of the spindle 21. As shown in FIG. The velor material 22 includes a base fabric 23 made of a woven fabric and a plurality of pile yarns 24 woven by a pile weave so as to be raised on the surface of the base fabric 23. The base fabric 23 and the pile yarn 24 of the velor material 22 have a low coefficient of dynamic friction and have wear resistance and appropriate heat resistance, for example, synthetic fibers made of polyolefin resin, polyamide resin, polyester resin, fluororesin, etc. Semi-synthetic fibers made of rayon or the like are used. In particular, when the brush 20 requires a charging function, a charge removal function, and the like, such as the charging brush 12a and the cleaning brush 18a, a conductive fiber provided with conductivity is used. In addition, a coating layer 25 formed of a synthetic resin coating agent is provided on the back surface of the base fabric 23. And the said brush 20 is formed in the roll shape by apply | coating an adhesive agent on the surface of the spindle 21, and winding the velor material 22 on it so that a spiral shape may be made.
[0012]
The brush 20 exhibits the specific functions as described above by rotating while the tip of the pile yarn 24 of the velor material 22 is in sliding contact with the surface of the photosensitive drum 11. In the brush 20, the pile yarn 24 functions as a result of the pile yarn 24 falling down or the toner 15 adhering to the pile yarn 24 due to the sliding contact with the photosensitive drum 11 for a long time. It will not be able to fully demonstrate. For this reason, the brush 20 is periodically replaced with a new one. The used brush 20 collected from the inside of the image forming apparatus is reused in order to produce a regenerated roll brush, and the regenerated roll brush is used as a new brush 20 in the image forming apparatus.
[0013]
Next, a method for producing the regenerated roll brush will be described.
The regenerated roll brush is manufactured by subjecting the used brush 20 to a regenerating process. The regeneration process includes a process of removing the used brush 20, a process of raising the used brush 20, and a shearing process on the brush 20 after the removal process and the raised process. And a process of applying.
[0014]
The removal treatment is performed using an air blow device or a vacuum suction device. This air blow device is for blowing air of a predetermined pressure onto the used brush 20. On the contrary, the vacuum suction device is for performing vacuum suction on the used brush 20. Then, fine powder particles adhering to the velor material 22 are removed from the used brush 20 which has been subjected to air blowing or vacuum suction by an air blow device or a vacuum suction device.
[0015]
When performing a removal process using the said air blow apparatus, the method of spraying air on the whole brush 20 and the method of spraying air on a part of brush 20 are selected as needed. For example, since the developing brush 14a and the cleaning brush 18a mentioned above are always in contact with the toner 15, a method of spraying air over the entire brush 20 is preferable, and the charging brush 12a is less likely to come into contact with the toner 15. A method of spraying air on a part is preferable. The direction in which the air is blown is preferably a direction along the axial direction of the brush 20. This is because, when air is blown from the radial direction of the brush 20, the blown-off fine particles may enter from the surface layer of the velor material 22 into the inner depth.
[0016]
The air to be sprayed may be either cold air or hot air. In particular, it is preferable to use warm air when not only the fine particles are removed in the removal process but also the pile yarn 24 is raised. In this case, the temperature of the air is preferably 60 to 100 ° C. If the temperature is lower than 60 ° C., the pile yarn 24 may not be raised sufficiently. If the temperature is higher than 100 ° C., the pile yarn 24 may be thermally deformed. On the contrary, the pile yarn 24 may be arranged in an uneven manner or the hair may fall down. There is a possibility of reattaching to the thread 24.
[0017]
The pressure of the sprayed air is preferably 0.098 to 0.5 MPa. When the pressure is less than 0.098 MPa, the fine particles cannot be sufficiently removed, and even if the pressure is higher than 0.5 MPa, the ability to remove the fine particles is not improved any more. May cause inconveniences such as uneven arrangement of the yarns or the pile yarns 24 coming off. The time for blowing air is preferably 5 to 200 seconds. When the time is less than 5 seconds, the fine particles cannot be sufficiently removed, and even if the time is longer than 200 seconds, the ability to remove the fine particles is not improved any more, and the manufacturing time is longer. As a result, there is a possibility that the production amount may be reduced, and problems such as an increase in manufacturing cost may occur.
[0018]
In addition to the toner 15 listed above, fine powder particles removed by the removal treatment include abrasives made of paper powder, zinc stearate, etc., dust, fluff generated from the velor material 22, particularly the pile yarn 24, etc. Is also included. In the image forming apparatus, these fine powder particles are charged with a high rate of static electricity, and there is a possibility that the fine powder particles cannot be sufficiently removed only by air blowing and vacuum suction. For this reason, it is preferable to perform a removal process in a static elimination atmosphere. As a method of performing the removal treatment in a static elimination atmosphere, there are a method of charging the brush 20 positively or negatively so that the fine particles have a polarity different from the charged polarity, and an air ionizer for ionizing air. And the like, and a method of neutralizing the inside of the apparatus and the work table for performing the removal process. In particular, when the removal treatment is performed by blowing air, a method of ionizing the air blown so that the fine particles have a polarity different from the charged polarity and imparting a static elimination effect may also be mentioned.
[0019]
The raising process is performed on the used brush 20 after the removing process, and is performed to raise the pile yarn 24 that has fallen. The raising process includes a step of performing a primary raising process for scratching the pile yarn 24 with a needle-like body and roughly raising the pile yarn 24 using the heat and pressure of water vapor, And a step of performing secondary raising treatment for raising the hair while arranging the shape and the like. In this embodiment, the used brush 20 is subjected to the primary raising process and then the secondary raising process.
[0020]
FIG. 1A and FIG. 1B are schematic views showing a raising roller 31 as a needle-like body used in the primary raising process. The raising roller 31 includes a cylindrical drum 33 that is rotatably supported by a rotating shaft 32, and a plurality of needles 34 that protrude from the outer peripheral surface of the drum 33. The needle 34 may be formed using a metal such as iron, copper, or stainless steel, or may be formed using a synthetic resin such as polyamide, polyester, polypropylene, or acrylic. The raising roller 31 is configured to be rotatable about a rotation shaft 32 at a predetermined rotation speed by a driving mechanism (not shown). A rotary moving device 35 is disposed in front of both side portions of the raising roller 31, and a used brush 20 is supported between the rotary moving devices 35. These rotational movement devices 35 are provided with a drive mechanism (not shown), and rotate the used brush 20 in a certain direction (clockwise in FIG. 1B).
[0021]
Both the rotational movement devices 35 are configured to be able to approach and separate the used brush 20 from the raised roller 31. The used brush 20 is disposed so that the pile yarn 24 can be brought into contact with the tip of the needle 34 of the raising roller 31 in a state where the raising roller 31 is approached by the rotary moving device 35. Then, when the used brush 20 rotates with respect to the raising roller 31 that rotates in this state, the pile yarn 24 is scratched and raised by the needle 34 of the raising roller 31.
[0022]
In the raising roller 31, the wire diameter of the needle 34 is preferably 0.02 to 2 mm. If the wire diameter is less than 0.02 mm, the strength of the needle 34 is not sufficient, and the pile yarn 24 may be broken, and if it is thicker than 2 mm, the pile yarn 24 may not be able to be scratched. The height of the needle 34 from the outer peripheral surface of the drum 33 is preferably 2 mm or more. When the height is less than 2 mm, there is a possibility that the pile yarn 24 cannot be sufficiently scratched and raised. The density of the needles 34 on the outer peripheral surface of the drum 33 is preferably 10 to 10,000 / cm.²It is. Density is 10 / cm²If it is less than 10,000, the pile yarn 24 cannot be scratched sufficiently and 10,000 pieces / cm²If the number is larger, there is a risk that problems such as the pile yarn 24 coming off or being cut may occur.
[0023]
When performing the primary raising process, the raising roller 31 is switched to rotate in the same direction as the used brush 20 or in a different direction as necessary. For example, when the used brush 20 rotates in the direction in which the pile yarn 24 has fallen, if the used brush 20 has been severely fallen, the raising roller 31 has been used so that the pile yarn 24 is fluffed. It is rotated in the same direction as the brush 20. On the contrary, if the used brush 20 has fallen to some extent, the raising roller 31 is rotated in a direction different from that of the used brush 20 so as to apply the pile yarn 24 with a scissors.
[0024]
The number of rotations of the raising roller 31 is preferably 3000 rpm or less. If the rotational speed is higher than 3000 rpm, there is a risk of problems such as the pile yarn 24 coming off or being cut. The number of rotations of the raising roller 31 is adjusted according to the degree of fall of the hair, and the lower limit thereof is not particularly defined, but it is possible to perform the primary raising process even when the raising roller 31 is stopped and only the brush 20 is rotated. Therefore, it is 0 rpm.
[0025]
In the used brush 20 subjected to the primary raising process, not all the pile yarns 24 fall down along the rotation direction of the brush 20, and some pile yarns 24 are in the axial direction of the brush 20. There is a possibility that the hair has fallen along. In such a case, a portion where the pile yarn 24 is not sufficiently raised occurs, and the portion may be defective. For this reason, the used brush 20 is configured to be able to reciprocate along the axial direction by the rotational movement device 35. Then, when the used brush 20 is rotated and reciprocated and brought into sliding contact with the raising roller 31, it is possible to raise the pile yarn 24 so that the entire pile yarn 24 extends in a substantially constant direction.
[0026]
FIG. 2A is a schematic diagram showing a state in which the secondary brushing process is performed on the used brush 20. In the secondary raising process, the used brush 20 is supported between the pair of rotational movement devices 35 mentioned above, and water vapor having a predetermined pressure is supplied from the nozzle 36 to the surface of the brush 20 while rotating the brush 20 in a certain direction. It is given by spraying. The used brush 20 sprayed with water vapor removes the entanglement of the pile yarn 24 when it is rolled, and the direction, alignment, shape, etc. of the pile yarn 24 are adjusted by the external force and heat energy of the water vapor. , Brushed.
[0027]
When the secondary raising process is performed, there are a method of spraying water vapor on the entire brush 20 and a method of spraying water vapor on a part of the brush 20, which are selected according to the state of the pile yarn 24 falling down. . The direction in which the water vapor is sprayed is preferably a direction along the axial direction of the brush 20. This is because when the steam is sprayed from the radial direction of the brush 20, the pile yarn 24 may fall over. The rotation speed of the brush 20 is preferably 3000 to 10,000 rpm. If the rotational speed is less than 3000 rpm, the pile yarn 24 cannot be raised sufficiently, and if it exceeds 10000 rpm, the pile yarns 24 may not be lined up and may cause problems such as hair fall.
[0028]
The temperature of the water vapor sprayed is preferably 80 to 100 ° C. If the temperature is lower than 80 ° C., the pile yarn 24 cannot be raised sufficiently. If the temperature is higher than 100 ° C., the pile yarn 24 may be thermally deformed. There is a possibility that problems such as falling will occur. The pressure of water vapor is preferably 0.098 to 0.5 MPa. When the pressure is less than 0.098 MPa, the pile yarn 24 cannot be raised sufficiently. When the pressure is higher than 0.5 MPa, the pile yarns 24 are unevenly arranged or the pile yarns 24 come off. May cause problems. The time for spraying water vapor is preferably 10 to 120 seconds. If the time is less than 10 seconds, the pile yarn 24 cannot be raised sufficiently. If the time is longer than 120 seconds, the effect of raising the pile yarn 24 is not improved. There is a possibility that problems such as a decrease in the amount and an increase in manufacturing cost may occur.
[0029]
The used brush 20 after performing the above-described raising process may have uneven piles of pile yarns 24 and rising from the surface of the base fabric 23. In such a case, the tip of the pile yarn 24 protrudes from the surface of the brush 20 in a part of the portion, and the contact of the entire brush 20 with the photosensitive drum 11 becomes uneven due to the protruding pile yarn 24. There is a risk that. And in order to eliminate the pile yarn 24 which protrudes from the surface of this brush 20, a shearing process is given.
[0030]
FIG. 2B is a schematic diagram showing a state in which the used brush 20 is subjected to shearing. The shearing apparatus includes a rotary blade 44 having a substantially cylindrical shape. The brush 20 is rotatably supported between the pair of rotational movement devices 35 mentioned above, and is configured to be able to approach and separate from the rotary blade 44. With the brush 20 approaching the rotary blade 44, the tip of the pile yarn 24 protruding from the surface of the brush 20 is cut by contacting the rotary blade 44, and the tip of the pile yarn 24 is trimmed. The shearing process may be performed not only for the purpose of cutting and aligning the ends of the pile yarn 24 but also for the purpose of removing a deteriorated portion at the tip of the pile yarn 24 due to a change with time. In this case, the pile tip of the pile yarn 24 is trimmed so that the deteriorated portion at the tip of the pile yarn 24 comes into contact with the rotary blade 44 and is cut. The used brush 20 subjected to the shearing process is regenerated as a regenerated roll brush, and the regenerated roll brush is installed in the image forming apparatus as a new brush 20 at the time of replacement.
[0031]
When shearing is performed, the rotation speed of the brush 20 is preferably 10 to 500 rpm, and the rotation speed of the rotary blade 44 is preferably 50 to 1000 rpm. If the number of rotations is less than 10 rpm and less than 50 rpm, the ends of the pile yarn 24 cannot be sufficiently cut, and if the number of rotations exceeds 500 rpm and 1000 rpm, problems such as unevenness of the ends of the pile yarn 24 may occur. .
[0032]
The effects exhibited by the above embodiment will be described below.
-The reproduction | regeneration roll-shaped brush of embodiment is manufactured by performing the reproduction | regeneration process to the used brush 20 using the used brush 20 collect | recovered at the time of replacement | exchange. This regeneration process comprises a removal process for removing fine particles such as toner 15 adhering to the used brush 20, and a raising process for raising the fallen pile yarn 24 of the used brush 20. ing. Then, by performing the removal process and the raising process, it is possible to cause the used brush 20 to exhibit substantially the same function as the new brush 20. Therefore, the used brush 20 can be reused as a material for the regenerated roll brush, and resources can be effectively used. In addition, the raw material of the regenerated roll brush is the used brush 20, and it is not necessary to newly manufacture the velor material 22, the support shaft 21, and the like, so that the manufacturing cost can be reduced accordingly. In addition, by reusing the used brush 20, it is possible to reduce the amount of used brush 20 discarded, and to reduce the processing cost that increases when it is discarded.
[0033]
The brush 20 after the removal process and the raising process is subjected to a shearing process. For this reason, even when the pile yarns 24 are lined up and the rise from the surface of the base fabric 23 is not uniform in the removal process and the raising process, the ends of the pile yarns 24 of the brush 20 are aligned with the photosensitive drum. 11 surfaces can be contacted uniformly. Further, at this time, a deteriorated portion at the tip of the pile yarn 24 due to a change with time can be removed. Therefore, it is possible to improve the transfer image obtained when the reproduction roll brush is used.
[0034]
Further, the removal process is performed in a static elimination atmosphere so as to erase static electricity charged in the fine powder particles attached to the brush 20. For this reason, the fine granular material adhering to the pile yarn 24 of the brush 20 can be favorably and efficiently removed without being affected by static electricity.
[0035]
-The primary raising process of the raising process is performed by bringing the rotating brush 20 into sliding contact with the raising roller 31 as a needle-like body having needles or comb teeth, and scratching the pile yarn 24 with the needles or comb teeth to raise. Is called. In this primary raising process, when the pile yarn 24 is scratched, the pile yarn 24 is squeezed from its root portion to the hair tip by a needle or comb teeth. Then, when the pile yarn 24 is squeezed, it becomes possible to scrape the fine powder particles that have entered the inner portion of the velor material 22 by the needles or comb teeth onto the surface of the velor material 22. Therefore, in the primary raising treatment removal processing, the pile yarn 24 that has fallen down can be raised, and in addition to this, fine particles that have entered the inner part of the velor material 22 are scraped out, and the cleanliness of the brush 20 is improved. be able to.
[0036]
In addition, this embodiment can also be changed and embodied as follows.
For example, the needle 34 may be heated by, for example, installing a heating device having a heater or the like in the drum 33 constituting the raising roller 31, and the primary raising process may be performed in this state. When configured in this way, the pile yarn 24 is thermally deformed by being heated via the needle 34, so that the pile yarn 24 can be raised efficiently and reliably. In this case, the heating temperature is preferably 80 ° C. or lower. If the heating temperature is higher than 80 ° C., the pile yarn 24 may be thermally deformed more than necessary, and on the contrary, the state of falling over the hair may be deteriorated. Although the minimum in particular of heating temperature is not prescribed | regulated, since it may perform a primary raising process without heating, it is room temperature, Preferably it is 10-20 degreeC.
[0037]
In the embodiment, the primary brushing process is performed on the used brush 20 and then the secondary brushing process is performed. However, the present invention is not limited thereto, and the primary brushing process and the secondary brushing process are performed on the used brush 20. You may perform a process simultaneously. That is, the used brush 20 may be brought into sliding contact with the raising roller 31 and water vapor may be sprayed from the nozzle 36 onto the surface of the brush 20 while scratching the pile yarn 24 with the needle 34. When comprised in this way, the manufacturing time of a reproduction | regeneration roll-shaped brush can be shortened, and the improvement of a production amount and the reduction of manufacturing cost can be aimed at.
[0038]
For example, the used brush 20 such as the charging brush 12a, in which the pile yarn 24 is in very small contact with the photosensitive drum 11 at the time of use, and the pile yarn 24 is hardly fallen after use. Is also present. In this way, when the regeneration process is performed on the used brush 20 in which the pile yarn 24 hardly falls down, the primary raising process is omitted in the raising process, and only the secondary raising process is performed. Also good. In the case of such a configuration, the production amount can be improved and the manufacturing cost can be reduced by simplifying the process.
[0039]
In the embodiment, the brushing process is performed after the removal process on the used brush 20, but the present invention is not limited to this, and the brushing process and the brushing process may be performed simultaneously. For example, the pile yarn 24 may be raised by performing vacuum suction or air blowing while the brush 20 is in sliding contact with the raising roller 31, and the fine particles adhering thereto may be removed. Alternatively, vacuum suction or air blowing is performed while the brush 20 is in sliding contact with the raising roller 31, and water vapor is blown onto the surface of the brush 20, thereby raising and cleaning the pile yarn 24 and removing fine particles. You may comprise so that it may perform.
[0040]
-For example, if the pile ends of the pile yarn 24 are aligned after the raising process and are hardly protruding from the surface of the brush 20 or the tip portion is hardly deteriorated, the shearing process is omitted. The brush 20 after the raising treatment may be a regenerated roll brush. When configured in this manner, the manufacturing time can be shortened and the production amount can be improved by the amount of omitting the shearing process.
[0041]
The roll brush is not limited to the charging brush 12a, the developing brush 14a, and the cleaning brush 18a described in the embodiment, and may be a transfer roller (not shown) provided in the transfer unit 16 as long as it is built in the image forming apparatus. It is good. When the roll-shaped brush is a transfer roller, the movable body corresponding to this is a transfer belt (not shown).
[0042]
The needle-like body is not limited to the raised roller 31, and may be a needle cloth 31 a in which a plurality of needles 34 are planted on a sheet-like base material 33 a as shown in FIG. 6, for example. In addition to this, for example, a comb body in which a plurality of comb teeth are extended from a long side edge of a plate-like body having a rectangular shape when viewed from the plane so as to extend in a short direction of the plate-like body may be used.
[0043]
