[0002] For example, JP-A-2007-15319 discloses a transportation device including a transportation belt for transporting a medium while supporting the medium, a reservoir tank capable of storing a cleaning fluid for cleaning the transportation belt, and a washing section for cleaning the transportation belt by using the cleaning fluid stored in the reservoir tank. The reservoir tank is provided with a discharge port for discharging the cleaning fluid.

[0003] In such a transportation device, as the transportation belt is cleaned, the cleaning fluid containing the foreign matter that has adhered to the transportation belt is returned to the reservoir tank. Therefore, in order to prevent the foreign matter contained in the cleaning fluid from a clogging the discharge port, the reservoir tank is provided with a partition wall surrounding the outlet.

[0004] However, in such a transportation device, when a predetermined amount or more of foreign matter is accumulated, the foreign matter flows into the drain port through the hole provided in the partition wall. As a result, foreign matter contained in the cleaning fluid may clog the discharge port.

[0005] KR 2016 0108147 discloses a system to clean an image receiving surface in an inkjet printer with a surface processing material. A printer cleaning apparatus includes a roller cleaning an image receiving surface with a surface processing material and having a cylindrical perforated wall surrounded by a foamed material.

[0009] Hereinafter, an embodiment of a transportation device and a recording device will be described. In the following description, a direction intersecting the vertical direction Z is referred to as a width direction X, and a direction intersecting the vertical direction Z and the width direction X is referred to as a length direction Y. The upward direction in the vertical direction Z is referred to as an upward direction Z1, and the downward direction in the vertical direction Z is referred to as a downward direction Z2.Recording device 11 and transportation device 14

[0010] As shown in FIG. 1, a recording device 11 may be an inkjet printer that performs recording on a medium 99 by ejecting ink, which is an example of liquid, onto the medium 99. The medium 99 is fabric, but may be, for example, paper.

[0011] The recording device 11 includes a recording section 12. The recording section 12 is configured to perform recording on the medium 99 by ejecting liquid onto the medium 99. The recording section 12 performs the recording on the medium 99, which is transported by a transportation belt 17 (described later). The recording section 12 may be a head. The recording section 12 may be a serial head or a line head. The serial head is the head that scans the medium 99 in the width direction X. The line head is the head that records all at once in the width direction X.

[0012] The recording section 12 includes a plurality of nozzles 13. Each of the plurality of nozzles 13 is configured to open in the downward direction Z2. Each of the plurality of nozzles 13 is configured to eject liquid.

The transportation direction D may be along the length direction Y. The transportation device 14 may include a first roller 15 and a second roller 16. The first roller 15 is located upstream of the second roller 16 in the transportation direction D. The first roller 15 is located upstream of the recording section 12 in the transportation direction D. The second roller 16 is located downstream of the recording section 12 in the transportation direction D.

[0014] The transportation device 14 includes the transportation belt 17. The transportation belt 17 is configured to transport the medium 99 in a state of supporting the medium 99. The transportation belt 17 is wound around a plurality of rollers. The transportation belt 17 is wound around the first roller 15 and the second roller 16. When the first roller 15 rotates, the transportation belt 17 moves along the first roller 15 and the second roller 16.

[0015] The transportation belt 17 includes a support surface 18 that supports the medium 99. The support surface 18 is an outer peripheral surface of the transportation belt 17. The transportation belt 17 is, for example, a belt in which an adhesive is applied to the support surface 18. The medium 99 is adhered to the support surface 18 by an adhesive. Thus, the posture of the medium 99 is stabilized. The medium 99 may be adhered to the support surface 18 not only by the adhesive but also by, for example, an attraction force, an electrostatic force, an intermolecular force, or the like. In this way, the transportation belt 17 transports the medium 99 supported on the support surface 18 by moving along the first roller 15 and the second roller 16.

[0016] The transportation belt 17 may be soiled by transporting the medium 99. In particular, the support surface 18 tends to become dirty. For example, powder or fluff generated from the medium 99, dust in the air, a recording material from the recording section 12, or the like may adhere to the support surface 18. As a result, the support surface 18 is contaminated. When the support surface 18 is contaminated, there is a risk that the contamination may be attached to the medium 99.

The receiver section 66 is provided outside the reservoir tank 32. The receiver section 66 may be located below the removal section 65 in downward direction Z2. The receiver section 66 may be configured to open toward the upward direction Z1.

[0066] As shown in FIG. 4, the filter section 60 may include a detector section 67. That is, the transportation device 14 may include the detector section 67. Further, the recording device 11 may include the detector section 67. The detector section 67 detects the foreign matter 97 collected by the filter 61.

[0067] The detector section 67 may be an optical sensor. The detector section 67 may include a light projection section 67A and a light receiver section 67B. The light projection section 67A may be provided in the reservoir tank 32. The light receiver section 67B may be provided in the third discharge pipe 41. The light receiver section 67B is provided such that the third outlet 53 is located between the light receiver section 67B and the light projection section 67A. The light receiver section 67B is provided such that the filter 61 covering the third outlet 53 is positioned between the light projection section 67A and the light receiver section 67B. As described above, the light receiver section 67B may detect the foreign matter 97 when the light projected from the light projection section 67A is blocked by the foreign matter 97 collected by the filter 61.Filter control process

[0068] Here, the filter control process will be described with reference to FIG. 5. The filter control process is a process executed by the control section 22 at predetermined intervals.

[0069] As shown in FIG. 5, in Step S10, the control section 22 executes the collection amount detection processing. In this processing, the control section 22 detects the collection amount of the foreign matter 97 at the position of the filter 61 covering the third outlet 53 based on the detection signal from the detector section 67. When step S10 ends, the control section 22 changes the processing to step S11.

[0070] In step S11, the control section 22 determines whether or not the collection amount has exceeded a threshold value. The threshold value may correspond to a collection amount suitable for the movement of the filter 61. That is, the threshold value may correspond to a collection amount suitable for the movement of the filter 61. The threshold value may correspond to the collection amount when the detection signal is received from the detector section 67. When the control section 22 determines that the collection amount does not exceed the threshold value, it shifts the processing to step S13 without executing step S12. When the control section 22 determines that the collection amount exceeds the threshold value, it shifts the processing to step S12.

[0071] In step S12, the control section 22 executes a filter moving process. In this process, the control section 22 controls the filter moving section 62 so as to move the filter 61 by a predetermined distance along the moving path. In particular, the control section 22 moves the filter 61 from a position where a predetermined region of the filter 61 covers the third outlet 53 to a position where the predetermined region of the filter 61 does not cover the third outlet 53. The control section 22 moves the filter 61 from a position where a predetermined region of the filter 61 covers the third outlet 53 to a position where the predetermined region of the filter 61 does not touch the cleaning fluid 98. In this manner, the movement condition of the filter 61 may include the detection result detected by the detector section 67. That is, when it is determined that the collection amount exceeds the threshold value based on the detection result detected by the detector section 67, the control section 22 causes the filter moving section 62 to move the filter 61. When step S12 is completed, the control section 22 shifts the processing to step S13.

[0072] In step S13, the control section 22 determines whether or not the predetermined time has elapsed. In this process, the control section 22 determines that the predetermined time has elapsed when a predetermined date and time is reached. In a case where the control section 22 determines that the predetermined time has not elapsed, the control section 22 ends the filter control process without executing step S14. When the control section 22 determines that the predetermined time has elapsed, it shifts the process to step S14.

[0073] In step S14, the control section 22 executes the filter moving process as in step S12. As described above, the movement condition of the filter 61 may include a predetermined date and time. That is, the control section 22 causes the filter moving section 62 to move the filter 61 when a predetermined date and time is reached. When step S14 is completed, the control section 22 ends the filter control processing.

[0074] In this way, the control section 22 controls the filter moving section 62. In particular, the control section 22 causes the filter moving section 62 to move the filter 61 based on the detection result detected by the detector section 67. In addition, the control section 22 causes the filter moving section 62 to move the filter 61 when a predetermined time has elapsed.Operations of first embodiment

[0075] The operation of the first embodiment will be described.

[0076] As shown in FIG. 3, the filter 61 covers the third outlet 53 in the reservoir tank 32. Thus, the filter 61 can collect the foreign matter 97 contained in the cleaning fluid 98 stored in the reservoir tank 32 without discharging the foreign matter 97 to the third discharge pipe 41 via the third outlet 53.

[0077] When the movement condition of the filter 61 is satisfied, it moves by a predetermined distance along the movement path. As a result, the predetermined region of the filter 61 covering the third outlet 53 moves to a position outside the reservoir tank 32 where the predetermined region does not cover the third outlet 53 and does not touch the cleaning fluid 98. On the other hand, a partial region of the filter 61 that does not cover the third outlet 53 moves to a position that covers the third outlet 53.

[0078] Thereafter, as shown in FIG. 6, while the filter 61 is moving, the foreign matter 97 collected by the filter 61 is removed by the removal section 65 outside the reservoir tank 32. Then, the foreign matter 97 removed from the filter 61 by the removal section 65 is received in the receiver section 66 outside the reservoir tank 32. As a result, the foreign matter 97 received by the receiver section 66 can be discarded without being mixed with the cleaning fluid 98.Effects of first embodiment

[0079] Effects of the first embodiment will be described.

[0080] (1-1) It is possible to move the filter 61 so that the positional relationship between the predetermined region of the filter 61 and the third outlet 53 changes. Thus, the region where the foreign matter 97 is collected by the filter 61 can be moved with respect to the third outlet 53. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98.

[0081] (1-2) The transportation device 14 includes the removal section 65 that removes the foreign matter 97 collected by the filter 61. According to this configuration, the foreign matter 97 collected by the filter 61 can be removed from the filter 61 by the removal section 65. Accordingly, even when the filter 61 is reused, the foreign matter 97 can be appropriately collected by the filter 61. Accordingly, it is possible to increase the degree of contribution to the environment while reducing the frequency of replacement of the filter 61. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98, and it is possible to improve convenience for the user.

[0082] (1-3) The transportation device 14 includes the receiver section 66 for receiving the foreign matter 97 removed by the removal section 65. According to this configuration, the foreign matter 97 removed from the filter 61 can be received in the receiver section 66. Accordingly, it is possible to improve the certainty of receiving the foreign matter 97 removed from the filter 61 and to easily discard the foreign matter 97 removed from the filter 61. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98, and it is possible to improve convenience for the user.

[0083] (1-4) The filter 61 is movable while covering the third outlet 53. According to this configuration, even in a case where the filter 61 is moved such that the positional relationship between the predetermined region of the filter 61 and the third outlet 53 changes, the third outlet 53 is covered by the filter 61. Accordingly, it is possible to suppress the foreign matter 97 from flowing out from the third outlet 53 while maintaining a state in which the cleaning fluid 98 can be discharged from the third outlet 53. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98, and it is possible to improve convenience for the user.

[0084] (1-5) The control section 22 causes the filter moving section 62 to move the filter 61 based on the detection result detected by the detector section 67. According to this configuration, it is possible to move the filter 61 on the basis of the detection result of the foreign matter 97 collected by the filter 61. Accordingly, it is possible to move the filter 61 in consideration of the detection result. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98.

[0085] (1-6) The control section 22 causes the filter moving section 62 to move the filter 61 when a predetermined time has elapsed. According to this configuration, it is possible to move the filter 61 when the predetermined time elapses. Accordingly, it is possible to move the filter 61 in consideration of the elapse of time. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98.

[0086] (1-7) The filter moving section 62 can move the filter 61 such that the predetermined region of the filter 61 changes from a position covering the third outlet 53 to a position not covering the third outlet 53. According to this configuration, even in a case where the foreign matter 97 is collected in the predetermined region of the filter 61 that covers the third outlet 53, it is possible to move the filter 61 such that the predetermined region changes to a position that does not cover the third outlet 53. For this reason, it is possible to increase the certainty of collecting the foreign matter 97 by the filter 61. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98.

[0087] (1-8) The third outlet 53 discharges the cleaning fluid 98 to the recirculation section 40 that circulates the cleaning fluid 98 stored in the reservoir tank 32. According to this configuration, even when the cleaning fluid 98 stored in the reservoir tank 32 is circulated, the foreign matter 97 can be collected from the cleaning fluid 98 circulated by the filter 61. Thus, it is possible to suppress the foreign matter 97 from being contained in the circulated cleaning fluid 98. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98, and it is possible to improve convenience for the user.

[0088] The discharge frequency of the cleaning fluid 98 from the third outlet 53 tends to be higher than the discharge frequency of the cleaning fluid 98 from the first outlet 50, and tends to be higher than the discharge frequency of the cleaning fluid 98 from the second outlet 52. For this reason, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 included in the cleaning fluid 98 by moving the filter 61 which covers the third outlet 53 in which the discharge frequency of the cleaning fluid 98 is high.

[0089] (1-9) The third outlet 53 is provided in the bottom section 32A of the reservoir tank 32. Therefore, the filter 61 can collect not only the floating matter in the reservoir tank 32 but also the deposited matter in the reservoir tank 32. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98.SECOND EMBODIMENT

[0090] Next, a second embodiment will be described. In the second embodiment, the filter may be moved by rotation of the filter. The third outlet 53 may extend in a direction intersecting the vertical direction Z. In the following description, the same components as those of the above-described embodiment will be denoted by the same reference numerals and overlapping description thereof will be omitted or simplified, and components different from those of the above-described embodiment will be mainly described.Configuration of filter section 70

[0091] As shown in FIG. 7, the third outlet 53 is provided in a side section of the reservoir tank 32. It is configured to open in the horizontal direction. The third outlet 53 is configured to open in the horizontal direction. The third outlet 53 is positioned in a downward direction Z2 than the height of the liquid level of the cleaning fluid 98. The third discharge pipe 41 extends in the horizontal direction. That is, the discharge direction of the cleaning fluid 98 discharged from the third outlet 53 is the horizontal direction.

[0092] The cleaning fluid feeder 30 includes a filter section 70. The filter section 70 includes a filter 71 and a filter moving section 72. The filter 71 may be circular. The filter 71 is provided such that a top end 71A is higher than the liquid level of the cleaning fluid 98 stored in the reservoir tank 32 and a bottom edge 71B is lower than the liquid level of the cleaning fluid 98 stored in the reservoir tank 32 in the vertical direction Z. The filter 71 is configured to be movable by rotation. The filter 71 is movable in the state of covering the third outlet 53.

[0093] In this way, the filter 71 is movable so that the predetermined region changes from the position covering the third outlet 53 to the position not covering the third outlet 53. The filter 71 is movable from a position where the predetermined region does not cover the third outlet 53 to a position where the predetermined region covers the third outlet 53. That is, the filter 71 is movable so as to change the positional relationship between the predetermined region and the third outlet 53.

[0094] The filter moving section 72 may include a filter rotation shaft 73 and a drive section 74. The filter rotation shaft 73 extends in the horizontal direction. The filter rotation shaft 73 extends along a direction in which the third outlet 53 opens. The filter 71 is rotatably attached to the filter rotation shaft 73.

[0095] The drive section 74 rotates the filter rotation shaft 73. Therefore, when the filter rotation shaft 73 is rotated by the drive section 74, the filter 71 is rotated together with the filter rotation shaft 73. That is, the filter 71 is rotatable about an axis that is a rotation shaft along the discharge direction in which the cleaning fluid 98 is discharged from the third outlet 53.

[0096] In this manner, the filter moving section 72 can move the filter 71. The filter moving section 72 can move the filter 71 so that a predetermined region of the filter 71 changes from a position covering the third outlet 53 to a position not covering the third outlet 53. That is, the filter moving section 72 can move the filter 71 so as to change the positional relationship between the predetermined region of the filter 71 and the third outlet 53.

[0097] The filter section 70 may be provided with a removal section 75. The removal section 75 is provided at a position higher than the liquid level of the cleaning fluid 98 stored in the reservoir tank 32. The removal section 75 may or may not be housed in the reservoir tank 32. The removal section 75 is provided along the filter 71. The removal section 75 may be provided so as to be inclined in a direction opposite to the rotation direction of the filter 71.

[0098] The filter section 70 may includes a receiver section 76. The receiver section 76 is provided at a position higher than the liquid level of the cleaning fluid 98 stored in the reservoir tank 32. The receiver section 76 may or may not be housed in the reservoir tank 32.Effects of second embodiment

[0099] Effects of the second embodiment will be described.

[0100] (2-1) The filter 71 is rotatable about the rotation shaft that is an axis along the discharge direction in which the cleaning fluid 98 is discharged from the third outlet 53. According to this configuration, the filter 71 can be moved by a simple configuration, and the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98 can be suppressed.

[0101] (2-2) The discharge direction in which the cleaning fluid 98 is discharged from the third outlet 53 is a direction intersecting the vertical direction Z. The filter 71 is rotatable about the rotation shaft that is an axis along the discharge direction in which the cleaning fluid 98 is discharged from the third outlet 53. The filter 71 is provided such that the top end 71A is higher than the liquid level of the cleaning fluid 98 stored in the reservoir tank 32 and the bottom edge 71B is lower than the liquid level of the cleaning fluid 98 stored in the reservoir tank 32 in the vertical direction Z. According to this configuration, it is possible to remove the foreign matter 97 collected by the filter 71 at a position higher than the liquid level of the cleaning fluid 98 stored in the reservoir tank 32. Thus, it is possible to prevent the foreign matter 97 removed from the filter 71 from touching with the cleaning fluid 98 stored in the reservoir tank 32. Therefore, it is possible to increase the certainty of removing the foreign matter 97 collected by the filter 71. Therefore, it is possible to suppress the clogging of the third outlet 53 due to the foreign matter 97 contained in the cleaning fluid 98, and it is possible to improve convenience for the user.MODIFICATIONS

[0102] The present embodiment can be modified as follows. The present embodiment and the following modifications can be implemented in combination with each other within a range that is not technically contradictory. In the first embodiment, for example, the discharge direction of the cleaning fluid 98 discharged from the third outlet 53 may be a horizontal direction. Also in this case, the filter 61 is provided so as to cover the third outlet 53. In the second embodiment, for example, the discharge direction of the cleaning fluid 98 discharged from the third outlet 53 may be the vertical direction Z, and the filter section 70 may be configured such that the filter 71 rotates about the rotation shaft that is an axis along the discharge direction. That is, the filter 71 may be rotatable about the rotation shaft that is an axis along the vertical direction Z. The filters 61 and 71 may not always cover the third outlet 53. In other words, there may be a period in which the third outlet 53 are covered by the filters 61 and 71 and a period in which the third outlet 53 are not covered by the filters 61 and 71. The filters 61 and 71 may not cover the entire region of the third outlet 53 or may cover a part of the region of the third outlet 53. In other words, the third outlet 53 may be partially or entirely covered by the filters 61 and 71. Although the filters 61 and 71 are moved from the position where the predetermined area covers the third outlet 53 to the position where the predetermined area does not cover the third outlet 53, the predetermined area may be moved from the position where the predetermined area covers the entire area of the third outlet 53 to the position where the predetermined area covers a part of the area of the third outlet 53. That is, the positional relationship between the predetermined region of the filter 61 or 71 and the third outlet 53 may be changed. The third outlet 53 is an example of the discharge port, but is not limited thereto. The first outlet 50 may be an example of a discharge port. The second outlet 52 may be an example of the discharge port. At least one of the first outlet 50, the second outlet 52, and the third outlet 53 may be an example of the discharge port. In such a case, the filters 61 and 71 may be provided so as to cover both the second outlet 52 and the third outlet 53, or the filters may be provided so as to cover the second outlet 52 and the third outlet 53, respectively. The support tank 31 is configured not to be included in the reservoir tank 32, but may be configured to be included in the reservoir tank 32. In such a case, the reservoir tank 32 may correspond to the first reservoir tank, and the support tank 31 may correspond to the second reservoir tank. The support tank 31 and the reservoir tank 32 may be integrally provided. The detector section 67 outputs the detection signal to the control section 22 when the collection amount of the foreign matter 97 collected in the filters 61 and 71 exceeds the threshold value, but is not limited thereto. For example, the detector section 67 may output a detection signal corresponding to the collection amount of the foreign matter 97 collected in the filters 61 and 71 to the control section 22. In this case, the control section 22 may specify the collection amount of the foreign matter 97 corresponding to the detection signal based on the detection signal from the detector section 67, and determine whether or not the collection amount of the foreign matter 97 exceeds a threshold value. The detector section 67 may be, for example, an imaging capture section that captures images. In this case, the control section 22 may analyze the image data captured by the detector section 67 and detect the collection amount of the foreign matter 97 collected by the filters 61 and 71 based on the analysis result. The detector section 67 may be, for example, a pressure sensor. The detector section 67 may be provided in the third discharge pipe 41. When the fluid pressure of the cleaning fluid 98 flowing through the third discharge pipe 41 becomes higher than the reference fluid pressure, the control section 22 may determine that the collection amount of the foreign matter 97 collected by the filters 61 and 71 exceeds the threshold value. The control section 22 may compare the collection amount of the foreign matter 97 collected by the filters 61 and 71 with a plurality of threshold values. Specifically, the control section 22 may move the filters 61 and 71 when the collection amount of the foreign matter 97 collected in the filters 61 and 71 exceeds a first threshold value, and may perform the error notification when the collection amount of the foreign matter 97 exceeds a second threshold value larger than the first threshold value. The control section 22 may store a determination date and time when it is determined that the collection amount of the foreign matter 97 collected in the filters 61 and 71 exceeds the threshold value in the memory, and may perform an error notification when it is determined that the collection amount of the foreign matter 97 exceeds the threshold value before a predetermined time elapses from the previous determination date and time. The control section 22 may store the date and time of the previous movement of the filters 61 and 71 in the memory, and may determine that the predetermined time has elapsed when a predetermined time has elapsed from the date and time of the previous movement of the filters 61 and 71. That is, the control section 22 may cause the filter moving sections 62 and 72 to move the filters 61 and 71 when a predetermined time has elapsed. The cleaning fluid feeder 30 may be configured to supply the cleaning fluid 98 to the cleaning roller 24 and the brush roller 27 by spraying or dropping the cleaning fluid 98 toward the cleaning roller 24 and the brush roller 27. The liquid ejected by the recording section 12 is not limited to ink, and may be, for example, a liquid material in which particles of a functional material are dispersed or mixed in a liquid. For example, the recording section 12 may eject a liquid body containing a material such as an electrode material or a pixel material used for manufacturing a liquid crystal display, an electroluminescence display, a surface emitting display, or the like in a dispersed or dissolved form. As used herein, the phrase "at least one of" means one or more of the desired options. As an example, the phrase "at least one of" as used herein means only one option if the number of options is two, or both of the two options. As another example, the expression "at least any" as used herein means only one option or a combination of any two or more options when the number of options is three or more.
