Definitions
- the present invention relates to printing apparatuses.
- Ink jet printing apparatuses that print images or the like onto a medium such as cotton, silk, or wool by ejecting a liquid such as ink from a head having nozzles have been used for some time.
- a medium such as cotton, silk, or wool
- Such a medium has fluff on its surface, and the fluff or dust stirred up by vertical vortices produced by relative movement between the head and the medium during printing may adhere to the head and lead to ejection malfunctions in the nozzles.
- printing apparatuses having a function for removing the fluff or dust on the surface of the medium (called simply "fluff” hereinafter) before printing have been proposed.
- JP-A-2015-89636 discloses a printing apparatus that removes deposits adhering to a printing surface of a medium by bringing the printing surface into contact with an adhesive roller.
- a printing apparatus includes a medium support unit that transports a medium in a transport direction while supporting the medium, a medium supply unit that supplies the medium to the medium support unit, a printing unit including a head that ejects a liquid onto the medium while moving relative to the medium, and a rotating member provided in a position facing the medium between the medium supply unit and the printing unit.
- the rotating member has a rotating shaft longer in an intersecting direction that is orthogonal to the transport direction, and recesses and protrusions that form a repeating uneven surface in a rotation direction of the rotating member. The rotating member is rotated in a state where a predetermined gap is maintained between the rotating member and the medium.
- the printing apparatus includes the rotating member, which has a rotating shaft longer in the intersecting direction, and the rotating member including recesses and protrusions that form a repeating uneven surface in the rotation direction, the rotating member being located between the medium supply unit and the printing unit.
- the rotating member When the rotating member is rotated in a state where the predetermined gap is maintained between the rotating member and the medium, and one of the protrusions in the rotating member faces the surface of the medium, a gas between the medium and the rotating member is compressed, which causes the atmospheric pressure to rise locally at that area.
- the gas that has been pressurized by the compression decompresses, producing an airflow moving toward the inside of the recess. Accordingly, fluff adhering to the surface of the medium can be caused to rise and can then be removed.
- the printing apparatus according to this application example uses compression and decompression of the gas present between the medium and the rotating member to remove the fluff without making contact with the medium, and thus the aesthetic properties of the medium can be maintained.
- the printing apparatus further includes a suction unit that suctions the rotating member, and the rotating member rotates under a suction force from the suction unit.
- the printing apparatus includes the suction unit that suctions the rotating member, and the rotating member rotates under the suction force from the suction unit. Accordingly, the rotating member can be rotated efficiently. Furthermore, fluff that has risen from the medium can be collected by the suction force of the suction unit.
- the printing apparatus includes a rotating member driving unit that rotates the rotating member, and a suction force is produced by the rotating member driving unit rotating the rotating member.
- the printing apparatus includes the rotating member driving unit that rotates the rotating member, and the rotating member produces a suction force by rotating. Fluff that has risen from the medium can be collected by this suction force.
- the predetermined gap is less than or equal to a gap between the head and the medium, and a relative speed between the rotating member and the medium when the rotating member rotates is greater than or equal to a relative speed between the head and the medium when printing onto the medium.
- the gap between the rotating member and the medium is less than or equal to the gap between the head and the medium, and the rotating member rotates such that the relative speed between the rotating member and the medium is greater than or equal to the relative speed between the head and the medium. Accordingly, fluff that may be stirred up from the surface of the medium and adhere to the head during the relative movement of the head and the medium when printing onto the medium can be removed by the rotating member in advance.
- the printing apparatus includes a rotating member raising/lowering device that raises/lowers the rotating member.
- the printing apparatus includes the rotating member raising/lowering device that raises/lowers the rotating member, and can therefore handle media of different thicknesses.
- the rotating member raising/lowering device changes the predetermined gap in accordance with a type of the medium.
- the rotating member raising/lowering device of the printing apparatus changes the gap between the rotating member and the medium in accordance with the type of the medium, and thus fluff adhering to the surface of the medium can be favorably removed.
- the printing apparatus includes a detection unit that detects a height of the medium, and the rotating member raising/lowering device changes the predetermined gap in accordance with the height of the medium detected by the detection unit.
- the printing apparatus includes the detection unit that detects the height of the medium, and the rotating member raising/lowering device changes the gap between the rotating member and the medium in accordance with the height of the medium detected by the detection unit, and thus fluff adhering to the surface of the medium can be favorably removed.
- the rotating member has the recesses and the protrusions forming a repeating uneven surface in the intersecting direction.
- the rotating member has the recesses and the protrusions forming a repeating uneven surface in the intersecting direction. Accordingly, the recesses are defined by the protrusions formed in the rotation direction and the intersecting direction, and thus the force of the airflow produced when the compressed gas is decompressed by the recesses can be increased.
- the protrusions in the rotating member have chamfered portions in which at least one end portion along the rotation direction is chamfered.
- the protrusions in the rotating member have chamfered portions in which at least one end portion along the rotation direction is chamfered, and thus the effect of the protrusions compressing the gas can be increased. Additionally, damage to the medium can be reduced in situations where fluff having extended threads makes contact with the protrusions.
- the recesses in the rotating member are formed as concave depressions.
- the recesses in the rotating member are formed as concave depressions. Accordingly, a spiral airflow is produced when the compressed gas is decompressed by the recesses, and thus the force of the airflow can be increased.
- the protrusions in the rotating member are formed having a broader surface area than the recesses.
- the protrusions in the rotating member have a broader surface area than the recesses, and thus the effect of the protrusions compressing the gas can be increased.
- Figs. 1 to 3 , 5 , 6 , 10 to 14 , and 16 illustrate an X axis, a Y axis, and a Z axis as three mutually-orthogonal axes for the sake of simplicity, with the tip side of the arrows indicating the axial directions being "+ sides” and the base end sides being "- sides”.

- Fig. 8 is a flowchart illustrating a fluff removal method.
- Fig. 9 is a table illustrating a relationship between a medium type, a head height, and a rotating member height. A method for removing fluff from the medium 95 in the printing operations performed by the printing apparatus 100 will be described next with reference to Figs. 3 and 5 to 9 .
- Step S1 is a print information reception step of receiving print information.
- the controller 1 receives print data, print information, or the like of an image to be recorded on the medium 95, inputted from the input device 6, and stores that data, information, or the like in the storage unit 4.
- Step S2 is a rotating member height determination step of determining the height of the rotating member 73.
- Information of the type of the medium 95 being used is included in the print information received in step S1.
- the storage unit 4 holds, in advance, a table indicating a relationship between the medium type, the head height, and the rotating member height, as indicated in Fig. 9 , for example.
- Types of the medium 95 that can be printed onto by the printing apparatus 100 are registered in the table held in the storage unit 4.
- a head height and a rotating member height are defined for each type of the medium 95.
- “Head height” refers to the height of the head unit 42 relative to the medium 95 (that is, a gap between the head unit 42 and the medium 95)
- “rotating member height” refers to the height of the rotating member 73 relative to the medium 95 (a predetermined gap between the rotating member 73 and the medium 95).
- cotton contains fluff with long hairs, and the height of the fluff varies greatly, and thus if the type of the medium 95 is cotton, the head height is set to a comparatively high 4 mm.
- the rotating member 73 will not damage the medium 95 even if the rotating member 73 makes contact with the ends of the fluff, and thus the rotating member height is set to 3.5 mm, which is slightly lower than the head height.
- Nylon meanwhile, has a lower fluff height, and thus if the type of the medium 95 is nylon, the head height and the rotating member height are both set to the same 2 mm.
- the predetermined gap between the rotating member 73 and the medium 95 is changed in accordance with the type of the medium. Additionally, the predetermined gap between the rotating member 73 and the medium 95 is set to be less than or equal to the gap between the head unit 42 and the medium 95.
- Step S3 is a rotating member raising/lowering step of raising/lowering the rotating member 73.
- the controller 1 raises/lowers and holds the rotating member 73 to the rotating member height (the predetermined gap between the rotating member 73 and the medium 95) determined in step S2 by controlling the rotating member raising/lowering device 75.
- Step S4 is a suction step of suctioning the rotating member 73.
- the controller 1 controls the suction unit 72 to cause the rotating member 73 to rotate under the suction force of the suction unit 72.
- a relative speed between the rotating member 73 and the medium 95 when the rotating member 73 rotates is preferably greater than or equal to a relative speed between the head unit 42 and the medium 95 when the medium 95 is printed onto.
- the rotating member 73 rotates away from the suction port 71a and toward the exhaust port 71b. As illustrated in Fig. 3 , when the rotating member 73 rotates and one of the protrusions 73b approaches the medium 95, a gas present between the rotating member 73 and the medium 95 is compressed by the protrusion 73b toward the medium 95 side such that the atmospheric pressure at that area rises locally.
- the printing apparatus 100 uses compression and decompression of the gas present between the medium 95 and the rotating member 73 to remove the fluff without making contact with the medium 95, and thus the aesthetic properties of the medium 95 can be maintained.
- the rotating member 73 rotates with the predetermined gap between the rotating member 73 and the medium 95 being less than or equal to the gap between the head unit 42 and the medium 95, and with the relative speed between the rotating member 73 and the medium 95 being greater than or equal to the relative speed between the head unit 42 and the medium 95. Accordingly, fluff that may be stirred up from the surface of the medium 95 and adhere to the head unit 42 during the relative movement of the head unit 42 and the medium 95 when printing onto the medium 95 can be removed by the fluff removal section 70 in advance.
- Step S5 is a sub-scanning step in which the transport belt 23 is transported in the transport direction.
- the controller 1 controls the belt driving roller 25 to move in the transport direction.
- the medium 95 facing the rotating member 73 upon the transport roller 22 also moves in the transport direction (the +X-axis direction).
- Step S6 is a main scanning step in which ink is ejected toward the medium 95.
- the controller 1 controls the head unit 42 and the carriage movement section 45 to make a main scan in which ink is ejected toward the medium 95 from the head unit 42 while moving the carriage 43 mounting the head unit 42 in the width direction of the medium 95 (the Y-axis direction) intersecting with the transport direction.
- Step S7 is a step of confirming whether there is a next line of print data.
- the controller 1 determines whether there is a next line of print data by referring to the print data held in the storage unit 4. If there is a next line of print data (step S7: Yes), the process returns to step S5, and steps S5 to S7 are repeated. As a result, the main scan and the sub scan are repeated whilst suction is continued, and an image or the like is printed onto the medium 95. However, if there is not a next line of print data (step S7: No), the controller 1 stops the driving of the suction unit 72 and ends the printing operations of the printing apparatus 100.
- the configuration may be such that the rotating member 73 includes a motor and rotates under the driving of the motor. This makes it possible to easily control the number of rotations of the rotating member 73.
- the embodiment describes a configuration in which the fluff removal section 70 including the rotating member 73 is provided above the transport roller 22 as an example, the configuration may be such that the fluff removal section is provided upstream from the printing unit 40 (above the transport belt 23 serving as the medium support unit, for example).
- the embodiment describes a configuration in which the fluff removal section 70 is provided in a serial head-type printing apparatus 100 that ejects ink onto the medium 95 while moving the head unit 42 in the width direction of the medium 95
- the configuration is not limited thereto.
- the same effects can be achieved by a configuration in which the fluff removal section is provided in a line head-type printing apparatus that ejects ink from a fixed head unit, which is preferably longer than the width of the medium 95, while moving the medium in the transport direction.
- the printing apparatus 100 according to the embodiment can achieve the following effects.
- the printing apparatus 100 includes the rotating shaft 74, which is longer in the intersecting direction (the Y-axis direction), and the rotating member 73, which has the recesses 73a and the protrusions 73b formed along the rotation direction.
- the printing apparatus 100 also includes the suction unit 72 that suctions the rotating member 73 so as to cause the rotating member 73 to rotate. Accordingly, the rotating member 73 is rotated efficiently by the suction unit 72, without needing to be powered. Furthermore, the fluff that has risen from the medium 95 can be collected by the suction force of the suction unit.
- the printing apparatus 100 uses compression and decompression of the gas present between the medium 95 and the rotating member 73 to remove the fluff without making contact with the medium 95, and thus the aesthetic properties of the medium 95 can be maintained.
- the printing apparatus 100 includes the rotating member raising/lowering device 75 that raises/lowers the rotating member 73, and can therefore handle media 95 of different thicknesses.
- the printing apparatus 100 changes the predetermined gap between the rotating member 73 and the medium 95 in accordance with the type of the medium 95, and thus the fluff can be removed from the medium 95 in a favorable manner.
- the rotating member 73 of the printing apparatus 100 rotates with the predetermined gap between the rotating member 73 and the medium 95 being less than or equal to the gap between the head unit 42 and the medium 95, and with the relative speed between the rotating member 73 and the medium 95 being greater than or equal to the relative speed between the head unit 42 and the medium 95. Accordingly, fluff that may be stirred up from the surface of the medium 95 and adhere to the head unit 42 during the relative movement of the head unit 42 and the medium 95 when printing onto the medium 95 can be removed by the fluff removal section 70 in advance.
- Fig. 10 is a schematic diagram illustrating the overall configuration of a printing apparatus according to a second embodiment.
- Fig. 11 is a plan view illustrating the configuration of a detection unit.
- Fig. 12 is a side view illustrating the configuration of the detection unit.
- Fig. 13 is a side view illustrating the configuration of a fluff removal section.
- the printing apparatus 200 includes the medium transport section 20, the medium contact section 60, the printing unit 40, the drying unit 27, a fluff removal section 170, the cleaning unit 50, a detection unit 180, and so on.
- the detection unit 180 is provided between the printing unit 40 and the belt rotation roller 24, and detects the height of the medium 95. As illustrated in Figs. 11 and 12 , the detection unit 180 is constituted by a first detection unit 181, a second detection unit 182, a third detection unit 183, a fourth detection unit 184, and a reflecting portion 185.
- the first to fourth detection units 181, 182, 183, and 184 are localized to one side in the width direction of the transport belt 23 (the -Y-axis side).
- the first detection unit 181, the second detection unit 182, the third detection unit 183, and the fourth detection unit 184 are provided in that order from the upstream to downstream in the transport direction. Additionally, as illustrated in Fig. 12 , the first detection unit 181, the second detection unit 182, the third detection unit 183, and the fourth detection unit 184 are provided so that the installation positions thereof become higher, in that order, upward from the transport belt 23 (the +Z-axis direction).
- the reflecting portion 185 is provided on the other side in the width direction of the transport belt 23 (the +Y-axis side).
- the reflecting portion 185 is arranged facing the first to fourth detection units 181, 182, 183, and 184 with the transport belt 23 located therebetween in the width direction.
- the reflecting portion 185 reflects light L emitted by the first to fourth detection units 181, 182, 183, and 184.
- the first to fourth detection units 181, 182, 183, and 184 are reflective photosensors, each including a light-emitting unit (not illustrated) that emits light and a light-receiving unit (not illustrated) that receives light.
- the first to fourth detection units 181, 182, 183, and 184 receive the light L emitted from the light-emitting units and reflected by the reflecting portion 185, and output voltages based on the received light amounts to the controller 1.
- the detection unit 180 is described as including the first to fourth detection units 181, 182, 183, and 184, the number thereof may be changed for example in accordance with the type of the medium 95. Additionally, the detection unit 180 may be constituted by a plurality of transmissive photosensors.
- the controller 1 can therefore detect the height of the medium 95. For example, if a thick piece of cotton is located on the transport belt 23 as the medium 95, the thickness (height) of the cotton blocks the light L from the first and second detection units 181 and 182, which are installed at a low height, and thus the first and second detection units 181 and 182 do not receive the light L.
- the third detection unit 183 outputs a low voltage value, due to part of the light-receiving unit thereof being blocked, whereas the fourth detection unit 184 outputs a high voltage value, due to the entire light-receiving unit thereof receiving the light L. In this manner, the height of the medium 95 can be detected on the basis of the voltages outputted from the first to fourth detection units 181, 182, 183, and 184.

- a collection unit (not illustrated) that collects fluff is provided in the exhaust port 171b of the housing 171.
- Fig. 17 is an electrical block diagram illustrating the electrical configuration of the printing apparatus. The electrical configuration of the printing apparatus 200 will be described next with reference to Fig. 17 .
- the controller 1 analyzes the voltage values outputted from the first to fourth detection units 181, 182, 183, and 184, and finds the height of the medium 95. Additionally, the controller 1 outputs control signals from the control circuit 5 in accordance with the height of the medium 95 in order to change a predetermined gap between the rotating member 173 and the medium 95, and raises/lowers the rotating member raising/lowering device 75 by controlling the driving of the motor included in the rotating member raising/lowering device 75. Furthermore, the controller 1 causes the rotating member 173 to rotate at a desired rotation number by controlling the rotating member driving unit 176 using control signals outputted from the control circuit 5.
- Fig. 18 is a flowchart illustrating a fluff removal method. A method for removing fluff from the medium 95 in the printing operations performed by the printing apparatus 200 will be described next with reference to Fig. 18 .
- step S101 is the same as step S1 described in the first embodiment and steps S105 to S107 are the same as steps S5 to S7 described in the first embodiment, and thus these steps will not be described.
- Step S102 is a medium height detection step of detecting the height of the medium 95.
- the controller 1 detects the height of the medium 95 from the voltage values outputted from the first to fourth detection units 181, 182, 183, and 184.
- Step S103 is a rotating member raising/lowering step of raising/lowering the rotating member 173.
- the controller 1 changes the predetermined gap between the rotating member 173 and the medium 95 in accordance with the height of the medium 95 detected by the first to fourth detection units 181, 182, 183, and 184, by controlling the rotating member raising/lowering device 75. Accordingly, fluff adhering to the surface of the medium 95 can be favorably removed.
- the controller 1 sets the predetermined gap between the rotating member 173 and the medium 95 to be substantially the same as the gap between the head unit 42 and the medium 95.
- Step S104 is a rotating member driving step of rotationally driving the rotating member 173.
- the controller 1 causes the rotating member 173 to rotate by controlling the rotating member driving unit 176. At this time, the controller sets a relative speed between the rotating member 173 and the medium 95 to greater than or equal to a relative speed between the head unit 42 and the medium 95 when the medium 95 is printed onto.
- the rotating member 173 rotates away from the suction port 171a and toward the exhaust port 171b. As illustrated in Fig. 14 , when the rotating member 173 rotates and one of the protrusions 173b, corresponding to the leading end of one of the vanes 177, approaches the medium 95, a gas present between the rotating member 173 and the medium 95 is compressed by the protrusion 173b toward the medium 95 side such that the atmospheric pressure at that area rises locally.
- the vanes 177 have crescent shapes tracing an arc in the rotation direction, and thus the gas can be favorably compressed at the leading ends thereof.
- the printing apparatus 200 uses the suction force produced by the rotation of the rotating member 173, and the compression and decompression of the gas present between the medium 95 and the rotating member 173, to remove the fluff without making contact with the medium 95, and thus the aesthetic properties of the medium 95 can be maintained.
- the printing apparatus 200 according to the embodiment can achieve the following effects.
- the printing apparatus 200 includes the detection unit 180, which is constituted by the first to fourth detection units 181, 182, 183, and 184 that detect the height of the medium 95.
- the controller 1 changes the predetermined gap between the rotating member 173 and the medium 95 in accordance with the height of the medium 95 detected by the first to fourth detection units 181, 182, 183, and 184. Accordingly, fluff adhering to the surface of the medium 95 can be favorably removed.
- the printing apparatus 200 includes the rotating member driving unit 176 that rotates the rotating member 173. Because the rotating member driving unit 176 rotates the rotating member 173, a suction force moving from the suction port 171a, through the recesses 173a, and toward the exhaust port 171b is produced in the rotating member 173. Accordingly, the fluff that has risen from the medium 95 can be exhausted to the exterior of the fluff removal section 170 and collected.
- the printing apparatus 200 uses the suction force produced by the rotation of the rotating member 173, and the compression and decompression of the gas present between the medium 95 and the rotating member 173, to remove the fluff without making contact with the medium 95, and thus the aesthetic properties of the medium 95 can be maintained.

- the protrusions 373b in the rotating member 373 have chamfered portions in which at least one end portion along the rotation direction is chamfered.
- the end portions of the protrusions 373b on the rotation direction side serve as chamfered portions 373c.
- the chamfered portions may be curved. Accordingly, the effect of compressing the gas by the protrusions 373b can be improved. Additionally, damage to the medium 95 can be reduced in situations where fluff having extended threads makes contact with the protrusions 373b.
- Fig. 21 is a perspective view illustrating a rotating member according to a third variation.
- the configuration of a rotating member 473 that can be used in the fluff removal section 70 according to the first embodiment will be described with reference to Fig. 21 .
- the rotating member 473 has a barrel shape or a circular column shape, and rotates in a circumferential direction. Recesses 473a in the rotating member 473 are formed as concave depressions (dimples) formed along the rotation direction and the intersecting direction.
- the rotating member 473 also has protrusions 473b in the regions aside from the recesses 473a. Accordingly, a spiral airflow is produced when a gas compressed between the protrusions 473b and the medium 95 with the rotation of the rotating member 473 is decompressed by the recesses 473a, and thus the force of the airflow is improved and fluff can be favorably removed from the medium 95.
- Fig. 22 is a perspective view illustrating a rotating member according to a fourth variation.
- the configuration of a rotating member 573 that can be used in the fluff removal section 70 according to the first embodiment will be described with reference to Fig. 22 .
- the rotating member 573 has a barrel shape or a circular column shape, and rotates in a circumferential direction. Recesses 573a in the rotating member 573 are formed as long, rounded depressions that are longer in the intersecting direction.
- the rotating member 573 also has protrusions 573b in the regions aside from the recesses 573a. Furthermore, the protrusions 573b are formed with a broader surface area than the recesses 573a. Setting the surface area of the protrusions 573b in the rotating member 573 to be broader than the surface area of the recesses 573a makes it possible to improve the effect of compressing the gas between the protrusions 573b and the medium 95.
- this variation describes the recesses 573a formed as long, rounded depressions as an example, the recesses are not limited to this shape.
- the recesses may be circular, rectangular, or the like, as in the preceding variation in Fig. 21 .
- Fig. 23 is a perspective view illustrating a rotating member according to a fifth variation.
- the configuration of a rotating member 673 that can be used in the fluff removal section 70 according to the first embodiment will be described with reference to Fig. 23 .
- the rotating member 673 according to this variation includes a motor (not illustrated) that rotationally drives the rotating member 673, and a suction unit 672 in place of the suction unit 72 described in the first embodiment. Note that the basic shape of the rotating member 673 is the same as the rotating member 73, and will thus not be described.
- the rotating member 673 includes a hollow rotating shaft 674. Communication holes 675 that communicate with the hollow rotating shaft 674 are provided in the recesses 73a.
- the suction unit 672 which sucks a gas from the recesses 73a via the hollow rotating shaft 674 and the communication holes 675, is provided at both ends of the rotating shaft 674.
- the suction unit 672 is what is known as a rotating fan. Accordingly, fluff on the surface of the medium 95, which has been caused to rise using the compression and decompression of a gas present between the rotating member 673 and the medium 95, can be exhausted efficiently.
- the hollow rotating shaft including the rotating fan described in this variation may also be applied in the rotating members described in the first to fourth variations.
- any of the rotating members of the variations can also be used in the second embodiment, the rotating member of the second embodiment can also be used in the first embodiment, and the rotating member in the first embodiment can also be used in the second embodiment.
- the detection unit 180 can be used in the first embodiment.
- the height of the rotating member can be set in the same manner as the second embodiment.
- the height of the rotating member in the second embodiment can be set in the same manner as the first embodiment.
