The driven pulley 64 and the driving pulley 66 are arranged below the chain 55. The drive pulley 66 is disposed on the downstream side in the transport direction of the paper P with respect to the driven pulley 64. A conveyor belt 62 is wound around the driven pulley 64 and the driving pulley 66. The drive unit 68 drives the drive pulley 66 to rotate in the counterclockwise direction in FIG. 2, so that the transport belt 62 rotates in the counterclockwise direction in FIG. That is, the conveyor belt 62 circulates in the counterclockwise direction in FIG.
そして、搬送ベルト62は、搬送機構53で搬送されている用紙Pの非画像面PBを吸着した状態で、自らの循環移動(移動の一例)により、用紙Pを搬送する。すなわち、搬送装置50では、用紙Pは、先端部が搬送機構53で把持され、その把持された先端部よりも後端側において非画像面PBが搬送ベルト62に吸着された状態で、搬送機構53及び搬送ベルト62によって搬送される。
Then, the transport belt 62 transports the paper P by its own circular movement (an example of movement) while adsorbing the non-image surface PB of the paper P transported by the transport mechanism 53. That is, in the transport device 50, the transport mechanism 50 is configured such that the front end portion of the paper P is gripped by the transport mechanism 53 and the non-image surface PB is adsorbed to the transport belt 62 on the rear end side of the gripped front end portion. 53 and the conveyor belt 62.
吸引装置70は、図2に示されるように、装置本体72と、支持体90と、ブロア76と、を有している。装置本体72は、搬送ベルト62の内周側に配置されている。この装置本体72は、内部が空洞とされた箱体で構成されている。装置本体72の上面には、吸引孔73が複数形成されている。装置本体72に対してブロア76が接続されている。これにより、ブロア76と装置本体72の内部とが連通している。
As shown in FIG. 2, the suction device 70 includes a device main body 72, a support 90, and a blower 76. The apparatus main body 72 is disposed on the inner peripheral side of the conveyance belt 62. This apparatus main body 72 is comprised by the box body by which the inside was hollow. A plurality of suction holes 73 are formed on the upper surface of the apparatus main body 72. A blower 76 is connected to the apparatus main body 72. Thereby, the blower 76 and the inside of the apparatus main body 72 are communicated.
支持体90は、上下方向(搬送ベルト62の厚み方向)を厚み方向とする板状に形成されている。この支持体90は、装置本体72の上面に固定されている。さらに、支持体90は、多孔質体で構成されている。具体的には、支持体90は、ポリエチレン(PE)などの樹脂材料で形成された発泡体で構成されている。支持体90は、多孔質体で構成されることで、厚み方向に通気可能となっている。なお、支持体90は、搬送ベルト62から荷重を受けても形状を維持しつつ、搬送ベルト62の荷重を支持可能な剛性を有している。
The support 90 is formed in a plate shape whose vertical direction (thickness direction of the conveyor belt 62) is the thickness direction. The support 90 is fixed to the upper surface of the apparatus main body 72. Furthermore, the support body 90 is comprised with the porous body. Specifically, the support 90 is made of a foam formed of a resin material such as polyethylene (PE). The support 90 is made of a porous material, and can be ventilated in the thickness direction. The support 90 has a rigidity capable of supporting the load of the conveyor belt 62 while maintaining the shape even when a load is received from the conveyor belt 62.
支持体90の上面は、図3に示されるように、搬送ベルト62を支持する支持面92とされている。具体的には、支持面92は、搬送ベルト62の吸着面62Aとは反対側において、すなわち、搬送ベルト62の内周面62Bにおいて、搬送ベルト62を支持している。
The upper surface of the support 90 is a support surface 92 that supports the conveyor belt 62 as shown in FIG. Specifically, the support surface 92 supports the conveyance belt 62 on the side opposite to the suction surface 62 </ b> A of the conveyance belt 62, that is, on the inner peripheral surface 62 </ b> B of the conveyance belt 62.
さらに、支持面92は、凹凸を有している。支持面92の凹凸は、例えば、研磨機等で表面を削り出すことで形成されている。支持面92に形成された凸部92A及び凹部92Bは、搬送ベルト62の移動方向(図3の矢印X方向)に沿って交互に並んで配置されている。したがって、支持面92は、搬送ベルト62の幅方向(図3の紙面の奥行方向)に見て、凹凸を有している。各凸部92A及び各凹部92Bは、搬送ベルト62の幅方向に延びており、搬送ベルト62の幅方向に長さを有している。なお、搬送ベルト62の幅方向は、搬送ベルト62の移動方向に直交し且つ支持面92に沿った直交方向の一例である。また、搬送ベルト62の幅方向は、用紙Pの厚み方向に直交し且つ搬送方向に直交する直交方向の一例である。ここで、搬送ベルト62の移動方向は、用紙Pの搬送方向と同一である。また、用紙Pの厚み方向は、搬送ベルト62の厚み方向と同一である。
Furthermore, the support surface 92 has irregularities. The unevenness of the support surface 92 is formed, for example, by scraping the surface with a polishing machine or the like. The convex portions 92 </ b> A and the concave portions 92 </ b> B formed on the support surface 92 are alternately arranged along the moving direction of the conveying belt 62 (the arrow X direction in FIG. 3). Therefore, the support surface 92 has irregularities when viewed in the width direction of the transport belt 62 (the depth direction of the paper surface of FIG. 3). Each convex portion 92 </ b> A and each concave portion 92 </ b> B extends in the width direction of the transport belt 62, and has a length in the width direction of the transport belt 62. The width direction of the transport belt 62 is an example of a direction orthogonal to the moving direction of the transport belt 62 and along the support surface 92. Further, the width direction of the conveyance belt 62 is an example of an orthogonal direction that is orthogonal to the thickness direction of the paper P and orthogonal to the conveyance direction. Here, the moving direction of the transport belt 62 is the same as the transport direction of the paper P. The thickness direction of the paper P is the same as the thickness direction of the transport belt 62.
そして、支持体90は、凹凸を有する支持面92にて搬送ベルト62を支持することで、搬送ベルト62を厚み方向に凹凸に変形させる。すなわち、本実施形態では、凹凸を有する支持面92が搬送ベルト62に接触して搬送ベルト62の荷重を支えることで、支持面92の凹凸に倣った凹凸形状に、搬送ベルト62が変形する。
The support 90 supports the transport belt 62 by the support surface 92 having unevenness, thereby deforming the transport belt 62 into unevenness in the thickness direction. That is, in this embodiment, the support surface 92 having unevenness comes into contact with the transport belt 62 and supports the load of the transport belt 62, so that the transport belt 62 is deformed into an uneven shape that follows the unevenness of the support surface 92.
なお、支持面92の凹凸の高さは、一例として、1mm以下とされている。ここでの凹凸の高さは、凹部92Bにおける最下の位置から凸部92Aにおける最上の位置までの高さである。
In addition, the height of the unevenness of the support surface 92 is set to 1 mm or less as an example. The height of the unevenness here is the height from the lowest position in the concave portion 92B to the uppermost position in the convex portion 92A.
支持面92の凹凸は、一例として、搬送ベルト62の移動方向に周期的に配置されている。この場合の凹凸のピッチは、一例として、20mm以上40mm以下とされている。凹凸のピッチは、凸部92Aの最上の位置における搬送ベルト62の移動方向に沿った間隔である。
The unevenness of the support surface 92 is periodically arranged in the moving direction of the conveyor belt 62 as an example. In this case, the uneven pitch is, for example, 20 mm or more and 40 mm or less. The uneven pitch is an interval along the moving direction of the conveyor belt 62 at the uppermost position of the convex portion 92A.
さらに、搬送ベルト62は、駆動プーリ66の回転駆動により周回することで、支持面92の凹凸に沿って移動する。これにより、搬送ベルト62の移動に伴って、搬送ベルト62の各部が厚み方向へ凹と凸とに交互に形状が変化する。
Furthermore, the conveyor belt 62 moves along the unevenness of the support surface 92 by rotating around the drive pulley 66. Thereby, with the movement of the conveyance belt 62, the shape of each part of the conveyance belt 62 alternately changes from concave to convex in the thickness direction.
ブロア76(図2参照)は、稼働されることで、装置本体72の内部から吸気して、装置本体72の内部を負圧にする。これにより、装置本体72の吸引孔73、支持体90の孔、及び搬送ベルト62の吸着孔(図示省略)を通じて、用紙Pが吸引されて用紙Pが搬送ベルト62に吸着される。なお、搬送ベルト62に対しても支持体90へ引き寄せられる吸引力が作用する。
When the blower 76 (see FIG. 2) is operated, the blower 76 sucks air from the inside of the apparatus main body 72 and makes the inside of the apparatus main body 72 have a negative pressure. Thus, the paper P is sucked through the suction holes 73 of the apparatus main body 72, the holes of the support 90, and the suction holes (not shown) of the transport belt 62, and the paper P is sucked by the transport belt 62. Note that a suction force attracted to the support 90 also acts on the transport belt 62.
このように、用紙Pが、搬送ベルト62に吸着されるので、形状が変化する搬送ベルト62による搬送に伴って、用紙Pの各部が厚み方向へ凹と凸とに交互に形状が変化する。すなわち、搬送部60は、用紙Pの搬送に伴って用紙Pの各部を厚み方向へ凹と凸とに交互に形状を変化させる。
As described above, since the paper P is attracted to the transport belt 62, the shape of each part of the paper P is alternately changed from a concave shape to a convex shape in the thickness direction with the transport by the transport belt 62 whose shape changes. In other words, the conveyance unit 60 changes the shape of each part of the paper P alternately to be concave and convex in the thickness direction as the paper P is conveyed.
乾燥部42は、図2に示されるように、搬送ベルト62の上側に配置されている。この乾燥部42は、搬送装置50によって搬送されている用紙Pを乾燥させる。乾燥部42は、一例として、熱風を送る送風部及び赤外線ヒータの少なくとも一方を有している。そして、乾燥部42では、熱風及び赤外線の少なくとも一方により用紙Pを加熱して、用紙Pの水分を蒸発させることで用紙Pを乾燥する。
The drying unit 42 is disposed on the upper side of the conveyor belt 62 as shown in FIG. The drying unit 42 dries the paper P being transported by the transport device 50. As an example, the drying unit 42 includes at least one of a blowing unit that sends hot air and an infrared heater. In the drying unit 42, the paper P is dried by heating the paper P with at least one of hot air and infrared rays to evaporate the moisture of the paper P.
(排紙部18)
排紙部18(図1参照)は、画像形成部20で画像が形成された後、乾燥装置40で乾燥された用紙Pが排出される排出部である。排紙部18は、図1に示されるように、用紙Pが積載された状態で、用紙Pを収容する。 (Discharge unit 18)
The paper discharge unit 18 (see FIG. 1) is a discharge unit that discharges the paper P dried by the dryingdevice 40 after an image is formed by the image forming unit 20. As shown in FIG. 1, the paper discharge unit 18 accommodates the paper P in a state where the paper P is stacked.
排紙部18(図1参照)は、画像形成部20で画像が形成された後、乾燥装置40で乾燥された用紙Pが排出される排出部である。排紙部18は、図1に示されるように、用紙Pが積載された状態で、用紙Pを収容する。 (Discharge unit 18)
The paper discharge unit 18 (see FIG. 1) is a discharge unit that discharges the paper P dried by the drying
(第一実施形態の作用効果)
画像形成装置10(図1参照)では、供給部(図示省略)から供給された用紙Pが、搬送ドラム30の外周面に吸着された状態で搬送ドラム30によって搬送される。搬送ドラム30によって搬送される用紙Pに対して、吐出ヘッド22C、22M、22Y及び22Kから、シアン(C)、マゼンタ(M)、イエロー(Y)及びブラック(K)の各色の水性インクが吐出される。これにより、用紙Pに画像が形成される。 (Operational effects of the first embodiment)
In the image forming apparatus 10 (see FIG. 1), the paper P supplied from a supply unit (not shown) is transported by thetransport drum 30 while being attracted to the outer peripheral surface of the transport drum 30. Cyan (C), magenta (M), yellow (Y), and black (K) water-based inks are ejected from the ejection heads 22C, 22M, 22Y, and 22K onto the paper P that is transported by the transport drum 30. Is done. As a result, an image is formed on the paper P.
画像形成装置10(図1参照)では、供給部(図示省略)から供給された用紙Pが、搬送ドラム30の外周面に吸着された状態で搬送ドラム30によって搬送される。搬送ドラム30によって搬送される用紙Pに対して、吐出ヘッド22C、22M、22Y及び22Kから、シアン(C)、マゼンタ(M)、イエロー(Y)及びブラック(K)の各色の水性インクが吐出される。これにより、用紙Pに画像が形成される。 (Operational effects of the first embodiment)
In the image forming apparatus 10 (see FIG. 1), the paper P supplied from a supply unit (not shown) is transported by the
吐出された水性インクを含んだ用紙Pは、搬送機構53のグリッパ57で先端部が把持されて搬送される。搬送機構53で搬送されている用紙Pは、第一ガイド80で搬送方向下流側へ案内された後、非画像面PBが搬送ベルト62に吸着される。これにより、用紙Pは、搬送機構53と搬送ベルト62とによって搬送される。
The paper P containing the discharged water-based ink is transported with its leading end gripped by the gripper 57 of the transport mechanism 53. The paper P being conveyed by the conveyance mechanism 53 is guided downstream in the conveyance direction by the first guide 80, and then the non-image surface PB is adsorbed to the conveyance belt 62. Thereby, the paper P is transported by the transport mechanism 53 and the transport belt 62.
搬送機構53と搬送ベルト62とによって搬送される用紙Pは、乾燥部42によって乾燥される。そして、用紙Pは、乾燥部42で乾燥されると、第二ガイド52で搬送方向下流側へ案内された後、排紙部18に収容される。
The paper P transported by the transport mechanism 53 and the transport belt 62 is dried by the drying unit 42. When the paper P is dried by the drying unit 42, the paper P is guided to the downstream side in the transport direction by the second guide 52 and then stored in the paper discharge unit 18.
ここで、支持体90が、凹凸を有する支持面92により搬送ベルト62を支持することで、搬送ベルト62を凹凸に変形させる。この搬送ベルト62は、支持面92の凹凸に沿って移動するので、搬送ベルト62の各部は、搬送ベルト62の移動に伴って、凹と凸とに交互に形状が変化する。
Here, the support 90 supports the transport belt 62 by the support surface 92 having unevenness, thereby deforming the transport belt 62 into unevenness. Since the transport belt 62 moves along the unevenness of the support surface 92, the shape of each part of the transport belt 62 changes alternately to a concave shape and a convex shape as the transport belt 62 moves.
そして、用紙Pは、この搬送ベルト62に吸着されているので、搬送ベルト62の移動によって用紙Pが搬送されると、用紙Pの各部が厚み方向へ凹と凸とに交互に形状が変化する。すなわち、搬送部60は、支持面92に支持された搬送ベルト62によって用紙Pを搬送することで、用紙Pの搬送に伴って、用紙Pの各部を厚み方向へ凹と凸とに交互に形状を変化させる。このため、用紙Pが上方及び下方(厚み方向の一方側及び他方側の一例)に交互に延ばされた状態で乾燥される。これにより、用紙Pを乾燥する際における用紙Pのしわの発生を抑制できる。また、用紙Pを乾燥する際における用紙Pのコックリング(波打ち)の発生も抑制できる。このため、用紙Pに形成される画像の画質の劣化を抑制できる。特に、この第一実施形態では、搬送部60は、搬送方向に直交する直交方向に見て、用紙Pの各部を厚み方向へ凹と凸とに交互に形状を変化させる。このため、用紙Pは、搬送方向に直交する直交方向において、上方及び下方(厚み方向の一方側及び他方側の一例)に交互に延ばされた状態で乾燥される。これにより、用紙Pを乾燥する際において用紙Pのしわが直交方向に発生するのを抑制できる。
Since the paper P is attracted to the transport belt 62, when the paper P is transported by the movement of the transport belt 62, the shape of each part of the paper P changes alternately to concave and convex in the thickness direction. . That is, the transport unit 60 transports the paper P by the transport belt 62 supported by the support surface 92, so that as the paper P is transported, each part of the paper P is alternately formed into a concave shape and a convex shape in the thickness direction. To change. For this reason, the paper P is dried in a state where the paper P is alternately extended upward and downward (an example of one side and the other side in the thickness direction). Thereby, generation | occurrence | production of the wrinkle of the paper P at the time of drying the paper P can be suppressed. Further, the occurrence of cockling (waving) of the paper P when the paper P is dried can be suppressed. For this reason, deterioration of the image quality of the image formed on the paper P can be suppressed. In particular, in the first embodiment, the transport unit 60 changes the shape of each part of the paper P alternately to be concave and convex in the thickness direction when viewed in the orthogonal direction orthogonal to the transport direction. For this reason, the paper P is dried in a state where the paper P is alternately extended upward and downward (an example of one side and the other side in the thickness direction) in the orthogonal direction orthogonal to the transport direction. Thereby, when the paper P is dried, wrinkles of the paper P can be suppressed from occurring in the orthogonal direction.
(第一実施形態の変形例)
第一実施形態では、支持面92の凹凸は、表面を削り出すことで形成されていたが、これに限られない。例えば、図4に示されるように、高さの異なる複数のブロック190を組み合わせることで、支持面92の凹凸を形成してもよい。この場合でも、凸部92A及び凹部92Bは、搬送ベルト62の移動方向(矢印X方向)に沿って交互に並んで配置されている。各凸部92A及び各凹部92Bは、搬送ベルト62の幅方向(図4の紙面の奥行方向)に延びており、搬送ベルト62の幅方向に長さを有している。さらに、図4に示す構成では、ブロック190を高さ方向(搬送ベルト62の移動方向に直交し、且つ、搬送ベルト62の幅方向に直交する方向)に移動可能な可動式、又は、高さが異なるブロック190に変更可能な構成としてもよい。この構成とすることで、用紙Pのしわの発生を抑制するだけでなく、用紙Pのヨレを補正することができる。 (Modification of the first embodiment)
In 1st embodiment, although the unevenness | corrugation of thesupport surface 92 was formed by carving out the surface, it is not restricted to this. For example, as shown in FIG. 4, the unevenness of the support surface 92 may be formed by combining a plurality of blocks 190 having different heights. Even in this case, the convex portions 92 </ b> A and the concave portions 92 </ b> B are alternately arranged along the moving direction (arrow X direction) of the conveyor belt 62. Each convex portion 92 </ b> A and each concave portion 92 </ b> B extends in the width direction of the transport belt 62 (the depth direction of the paper surface of FIG. 4), and has a length in the width direction of the transport belt 62. Furthermore, in the configuration shown in FIG. 4, the block 190 can be moved in the height direction (a direction perpendicular to the movement direction of the conveyance belt 62 and a direction perpendicular to the width direction of the conveyance belt 62), or a height that can be moved. It is good also as a structure which can be changed into the different block 190. With this configuration, not only the generation of wrinkles on the paper P but also the correction of the paper P can be corrected.
第一実施形態では、支持面92の凹凸は、表面を削り出すことで形成されていたが、これに限られない。例えば、図4に示されるように、高さの異なる複数のブロック190を組み合わせることで、支持面92の凹凸を形成してもよい。この場合でも、凸部92A及び凹部92Bは、搬送ベルト62の移動方向(矢印X方向)に沿って交互に並んで配置されている。各凸部92A及び各凹部92Bは、搬送ベルト62の幅方向(図4の紙面の奥行方向)に延びており、搬送ベルト62の幅方向に長さを有している。さらに、図4に示す構成では、ブロック190を高さ方向(搬送ベルト62の移動方向に直交し、且つ、搬送ベルト62の幅方向に直交する方向)に移動可能な可動式、又は、高さが異なるブロック190に変更可能な構成としてもよい。この構成とすることで、用紙Pのしわの発生を抑制するだけでなく、用紙Pのヨレを補正することができる。 (Modification of the first embodiment)
In 1st embodiment, although the unevenness | corrugation of the
また、図5に示されるように、搬送ベルト62の幅方向に延びるワイヤ180(線状の部材の一例)を支持体90の表面に設けることで、支持面92の凹凸を形成してもよい。この場合でも、凸部92A及び凹部92Bは、搬送ベルト62の移動方向(矢印X方向)に沿って交互に並んで配置されている。この構成によれば、支持体90の表面を削る等の加工をせずに、支持面92に凹凸を付与できるので、支持体90の製造が容易である。なお、支持体90の表面に設けられて支持面92の凹凸を形成する構造物としては、ワイヤ180に限られず、他の構造物を用いてもよい。
Further, as shown in FIG. 5, unevenness of the support surface 92 may be formed by providing a wire 180 (an example of a linear member) extending in the width direction of the transport belt 62 on the surface of the support 90. . Even in this case, the convex portions 92 </ b> A and the concave portions 92 </ b> B are alternately arranged along the moving direction (arrow X direction) of the conveyor belt 62. According to this configuration, since the unevenness can be imparted to the support surface 92 without processing such as cutting the surface of the support 90, the support 90 can be easily manufactured. The structure provided on the surface of the support 90 to form the unevenness of the support surface 92 is not limited to the wire 180, and other structures may be used.
〈第二実施形態〉
次に、図6及び図7を用いて、第二実施形態に係る画像形成装置200について説明する。前述の第一実施形態と同一機能を有する部分については、適宜、同一符号を付して、説明を適宜省略する。 <Second embodiment>
Next, theimage forming apparatus 200 according to the second embodiment will be described with reference to FIGS. 6 and 7. Portions having the same functions as those of the first embodiment described above are appropriately given the same reference numerals, and description thereof is omitted as appropriate.
次に、図6及び図7を用いて、第二実施形態に係る画像形成装置200について説明する。前述の第一実施形態と同一機能を有する部分については、適宜、同一符号を付して、説明を適宜省略する。 <Second embodiment>
Next, the
前述の画像形成装置10では、支持体90の支持面92は、搬送ベルト62の幅方向に見て、凹凸を有していた。これに対し、第二実施形態に係る画像形成装置200では、支持体90の支持面92は、搬送ベルト62の幅方向に見て、凹凸を有するのに加えて、図6に示されるように、搬送ベルト62の移動方向(図6の紙面の奥行方向)に見て、凹凸を有している。すなわち、画像形成装置200における支持面92には、搬送ベルト62の移動方向及び幅方向の各方向に見て、凹凸が形成されている。具体的には、支持面92に形成された凸部92A及び凹部92Bは、搬送ベルト62の移動方向及び幅方向において、互い違いに並んで配置されている。図6におけるY方向は、搬送ベルト62の幅方向を示す。
In the above-described image forming apparatus 10, the support surface 92 of the support 90 has irregularities when viewed in the width direction of the transport belt 62. On the other hand, in the image forming apparatus 200 according to the second embodiment, the support surface 92 of the support 90 is uneven as seen in the width direction of the transport belt 62, as shown in FIG. As seen in the moving direction of the conveying belt 62 (the depth direction of the paper surface of FIG. 6), the belt has irregularities. In other words, the support surface 92 in the image forming apparatus 200 has irregularities as viewed in the moving direction and the width direction of the transport belt 62. Specifically, the convex portions 92 </ b> A and the concave portions 92 </ b> B formed on the support surface 92 are alternately arranged in the moving direction and the width direction of the transport belt 62. The Y direction in FIG. 6 indicates the width direction of the conveyor belt 62.
なお、画像形成装置200は、支持面92の形状以外の構成については、画像形成装置10と同様とされている。
The configuration of the image forming apparatus 200 is the same as that of the image forming apparatus 10 except for the shape of the support surface 92.
画像形成装置200によれば、搬送ベルト62が支持面92の凹凸に沿って移動するので、搬送ベルト62の各部は、搬送ベルト62の移動に伴って、搬送ベルト62の移動方向(搬送方向)及び幅方向の各方向に見て、凹と凸とに交互に形状が変化する。そして、用紙Pは、この搬送ベルト62に吸着されているので、搬送ベルト62の移動によって用紙Pが搬送されると、用紙Pの搬送方向及び幅方向の各方向に見て、用紙Pの各部が厚み方向へ凹と凸とに交互に形状が変化する。すなわち、搬送部60は、支持面92により支持された搬送ベルト62により用紙Pを搬送することで、用紙Pの搬送方向及び幅方向の各方向に見て、用紙Pの各部を厚み方向へ凹と凸とに交互に形状を変化させる。このため、用紙Pが、搬送方向及び幅方向に延ばされた状態で乾燥される。これにより、用紙Pを乾燥する際において用紙Pのしわが搬送方向及び幅方向で発生するのを抑制できる。また、用紙Pを乾燥する際において用紙Pのコックリング(波打ち)が搬送方向及び幅方向で発生するのを抑制できる。なお、用紙Pの幅方向は、用紙Pの厚み方向に直交し且つ搬送方向に直交する直交方向の一例である。
According to the image forming apparatus 200, the conveyance belt 62 moves along the unevenness of the support surface 92, so that each part of the conveyance belt 62 moves in the movement direction (conveyance direction) of the conveyance belt 62 as the conveyance belt 62 moves. When viewed in the width direction, the shape changes alternately between concave and convex. Since the paper P is attracted to the transport belt 62, when the paper P is transported by the movement of the transport belt 62, each part of the paper P is viewed in each direction of the transport direction and the width direction of the paper P. However, the shape changes alternately to concave and convex in the thickness direction. In other words, the transport unit 60 transports the paper P by the transport belt 62 supported by the support surface 92, so that each part of the paper P is recessed in the thickness direction when viewed in the transport direction and the width direction of the paper P. The shape is changed alternately between convex and convex. For this reason, the paper P is dried in the state extended in the conveyance direction and the width direction. Thereby, when the paper P is dried, wrinkles of the paper P can be suppressed from occurring in the transport direction and the width direction. Further, when the paper P is dried, the occurrence of cockling (waving) of the paper P in the transport direction and the width direction can be suppressed. The width direction of the paper P is an example of an orthogonal direction orthogonal to the thickness direction of the paper P and orthogonal to the transport direction.
(第二実施形態の変形例)
第二実施形態においても、支持面92の凹凸は、高さの異なる複数のブロック190を組み合わせることで、支持面92の凹凸を形成してもよい(図4参照)。この場合でも、凸部92A及び凹部92Bは、搬送ベルト62の移動方向及び幅方向において、互い違いに並んで配置される。 (Modification of the second embodiment)
Also in the second embodiment, the unevenness of thesupport surface 92 may be formed by combining the plurality of blocks 190 having different heights (see FIG. 4). Even in this case, the convex portions 92 </ b> A and the concave portions 92 </ b> B are alternately arranged in the moving direction and the width direction of the transport belt 62.
第二実施形態においても、支持面92の凹凸は、高さの異なる複数のブロック190を組み合わせることで、支持面92の凹凸を形成してもよい(図4参照)。この場合でも、凸部92A及び凹部92Bは、搬送ベルト62の移動方向及び幅方向において、互い違いに並んで配置される。 (Modification of the second embodiment)
Also in the second embodiment, the unevenness of the
また、支持体90を平面視した図7に示されるように、ワイヤ180(直交方向に延びる線状の部材の一例)と、ワイヤ220(移動方向に延びる線状の部材の一例)と、を支持体90の表面に設けることで、支持面92の凹凸を形成してもよい(図5も参照のこと)。ワイヤ180は、搬送ベルト62の幅方向(Y方向)に延びるワイヤである。ワイヤ220は、搬送ベルト62の移動方向(X方向)に延びるワイヤである。
Further, as shown in FIG. 7 in plan view of the support 90, a wire 180 (an example of a linear member extending in the orthogonal direction) and a wire 220 (an example of a linear member extending in the movement direction) are provided. The unevenness of the support surface 92 may be formed by providing it on the surface of the support 90 (see also FIG. 5). The wire 180 is a wire extending in the width direction (Y direction) of the transport belt 62. The wire 220 is a wire extending in the moving direction (X direction) of the transport belt 62.
この構成においても、凸部92A及び凹部92Bは、搬送ベルト62の移動方向及び幅方向において、互い違いに並んで配置される。この構成によれば、支持体90の表面を削る等の加工をせずに、支持面92に凹凸を付与できるので、支持体90の製造が容易である。なお、支持体90の表面に設けられて支持面92の凹凸を形成する構造物としては、ワイヤ180及び220に限られず、他の構造物を用いてもよい。
Also in this configuration, the convex portions 92A and the concave portions 92B are alternately arranged in the moving direction and the width direction of the transport belt 62. According to this configuration, since the unevenness can be imparted to the support surface 92 without processing such as cutting the surface of the support 90, the support 90 can be easily manufactured. Note that the structure provided on the surface of the support 90 to form the unevenness of the support surface 92 is not limited to the wires 180 and 220, and other structures may be used.
さらに、第二実施形態では、凸部92A及び凹部92Bは、搬送ベルト62の移動方向及び幅方向において、不規則(ランダム)に配置されていてもよい。
Furthermore, in the second embodiment, the convex portions 92A and the concave portions 92B may be irregularly (randomly) arranged in the moving direction and the width direction of the transport belt 62.
